N° 820 Topic: Association of Age at Onset of Menopause and Time Since Onset of Menopause With Cardiovascular Outcomes, Intermediate Vascular Traits, and All-Cause Mortality: A Systematic Review and Meta-analysis.
Muka T et al JAMA Cardiol. 2016 Sep 14. doi: 10.1001/jamacardio.2016.2415. [Epub ahead of print] conducted a systematical review and meta-analyze studies evaluating the effect of age at onset of menopause and duration since onset of menopause on intermediate CVD end points, CVD outcomes, and all-cause mortality.

Of the initially identified references, 32 studies were selected that included 310 329 non-overlapping women. Outcomes were compared between women who experienced menopause younger than 45 years and women 45 years or older at onset;

the RR  (95% CIs) were 1.50 (1.28-1.76) for overall CHD, 1.11 (1.03-1.20) for fatal CHD, 1.23 (0.98-1.53) for overall stroke, 0.99 (0.92-1.07) for stroke mortality, 1.19 (1.08-1.31) for CVD mortality, and 1.12 (1.03-1.21) for all-cause mortality.

Outcomes were also compared between women between 50 and 54 years at onset of menopause and women younger than 50 years at onset; there was a decreased risk of fatal CHD (relative risk, 0.87; 95% CI, 0.80-0.96) and no effect on stroke.

 Time since onset of menopause in relation to risk of developing intermediate cardiovascular traits or CVD outcomes was reported in 4 observational studies with inconsistent results.
Conclusions and Relevance:

The findings of this review indicate a higher risk of CHD, CVD mortality, and overall mortality in women who experience premature or early-onset menopause.

Background
The 70-gene signature test (MammaPrint) has been shown to improve prediction of clinical outcome in women with early-stage breast cancer.
They sought to provide prospective evidence of the clinical utility of the addition of the 70-gene signature to standard clinical–pathological criteria in selecting patients for adjuvant chemotherapy.
Methods
In this randomized, phase 3 study, they enrolled 6693 women with early-stage breast cancer and determined their genomic risk (using the 70-gene signature) and their clinical risk (using a modified version of Adjuvant! Online). Women at low clinical and genomic risk did not receive chemotherapy, whereas those at high clinical and genomic risk did receive such therapy. In patients with discordant risk results, either the genomic risk or the clinical risk was used to determine the use of chemotherapy. The primary goal was to assess whether, among patients with high-risk clinical features and a low-risk gene-expression profile who did not receive chemotherapy, the lower boundary of the 95% confidence interval for the rate of 5-year survival without distant metastasis would be 92% (i.e., the noninferiority boundary) or higher.
Results
A total of 1550 patients (23.2%) were deemed to be at high clinical risk and low genomic risk. At 5 years, the rate of survival without distant metastasis in this group was 94.7% (95% confidence interval, 92.5 to 96.2) among those not receiving chemotherapy. The absolute difference in this survival rate between these patients and those who received chemotherapy was 1.5 percentage points, with the rate being lower without chemotherapy. Similar rates of survival without distant metastasis were reported in the subgroup of patients who had estrogen-receptor–positive, human epidermal growth factor receptor 2–negative, and either node-negative or node-positive disease.
Conclusions
Among women with early-stage breast cancer who were at high clinical risk and low genomic risk for recurrence, the receipt of no chemotherapy on the basis of the 70-gene signature led to a 5-year rate of survival without distant metastasis that was 1.5 percentage points lower than the rate with chemotherapy. Given these findings, approximately 46% of women with breast cancer who are at high clinical risk might not require chemotherapy.

N° 818 Topic: Extending Aromatase-Inhibitor Adjuvant Therapy to 10 Years
Treatment with an aromatase inhibitor for 5 years as up-front monotherapy or after tamoxifen therapy is the treatment of choice for hormone-receptor–positive early breast cancer in postmenopausal women. Extending treatment with an aromatase inhibitor to 10 years may further reduce the risk of breast-cancer recurrence.
Paul E. Goss, et al (N Engl J Med 2016; 375:209-219July 21, 2016DOI: 10.1056/NEJMoa1604700) published the results of a double-blind, placebo-controlled trial, involving 1918 women, to assess the effect of the extended use of letrozole for an additional 5 years, evaluating disease-free survival.. After a median follow-up of 6.3 years, there were 165 events involving disease recurrence or the occurrence of contralateral breast cancer (67 with letrozole and 98 with placebo) and 200 deaths (100 in each group). The 5-year disease-free survival rate was 95% (95% [CI], 93 to 96) with letrozole and 91% (95% CI; 89 to 93) with placebo (HR, 0.66; P=0.01). The rate of 5-year overall survival was not different. The annual incidence rate of contralateral breast cancer in the letrozole group was 0.21% (95% CI, 0.10 to 0.32), and the rate in the placebo group was 0.49% (95% CI, 0.32 to 0.67) (HR, 0.42; P=0.007). Bone-related toxic effects occurred more frequently among patients receiving letrozole than among those receiving placebo, including a higher incidence of bone pain, bone fractures, and new-onset osteoporosis. No significant differences between letrozole and placebo were observed in scores on most subscales measuring quality of life.
Conclusions
The extension of treatment with an adjuvant aromatase inhibitor to 10 years resulted in significantly higher rates of disease-free survival and a lower incidence of contralateral breast cancer than those with placebo, but the rate of overall survival was not higher with the aromatase inhibitor than with placebo.


N° 817 Topic: Danazol Treatment for Telomere Diseases
BACKGROUND
Genetic defects in telomere maintenance and repair cause bone marrow failure, liver cirrhosis, and pulmonary fibrosis, and they increase susceptibility to cancer. Historically, androgens have been useful as treatment for marrow failure syndromes. In tissue culture and animal models, sex hormones regulate expression of the telomerase gene. Danielle M. Townsley et al (N Engl J Med 2016; 374:1922-1931May 19, 2016DOI: 10.1056/NEJMoa1515319) administered the synthetic sex hormone danazol orally at a dose of 800 mg per day for a total of 24 months in a phase 1–2 prospective study involving patients with telomere diseases. The goal of treatment was the attenuation of accelerated telomere attrition, After 27 patients were enrolled, the study was halted early, because telomere attrition was reduced in all 12 patients who could be evaluated for the primary end point; in the intention-to-treat analysis, 12 of 27 patients (44%; 95% [CI], 26 to 64) met the primary efficacy end point. Unexpectedly, almost all the patients (11 of 12, 92%) had a gain in telomere length at 24 months as compared with baseline (mean increase, 386 bp [95% CI, 178 to 593]); in exploratory analyses, similar increases were observed at 6 months (16 of 21 patients; mean increase, 175 bp [95% CI, 79 to 271]) and 12 months (16 of 18 patients; mean increase, 360 bp [95% CI, 209 to 512]). Hematologic responses occurred in 19 of 24 patients (79%) who could be evaluated at 3 months and in 10 of 12 patients (83%) who could be evaluated at 24 months. Known adverse effects of danazol — elevated liver-enzyme levels and muscle cramps — of grade 2 or less occurred in 41% and 33% of the patients, respectively.
CONCLUSIONS
In this study, treatment with danazol led to telomere elongation in patients with telomere diseases.


N° 816 Topic: Dietary Patterns and Fractures in Postmenopausal Women Results From the Women’s Health Initiative
Bernhard Haring, et al
JAMA Intern Med. Published online March 28, 2016. doi:10.1001/jamainternmed.2016.0482
A Post hoc analysis was conducted of longitudinal data from the Women’s Health Initiative (WHI) observational study. Participants included 93 676 women who were eligible for the WHI if they were aged 50 to 79 years. The WHI food frequency questionnaire was used to derive nutrient and food intake at baseline. Diet quality and adherence were assessed by scores on the alternate Mediterranean Diet (aMED), a 9-category measure of adherence to a Mediterranean dietary pattern; the Healthy Eating Index 2010 (HEI-2010), a 100-point measure of 12 food components; the 11-item Alternate Healthy Eating Index 2010 (AHEI-2010); or the 8-component Dietary Approaches to Stop Hypertension (DASH) diet score.
Of the 93 676 participants, 90 014 were included in the analysis (mean [SD] age, 63.6 [7.4]) years. During a median follow-up time of 15.9 years, there were 2121 cases of hip fractures and 28 718 cases of total fractures. Women scoring in the highest quintile (Q5) of the aMED index had a lower risk for hip fractures (HR, 0.80; 95% CI, 0.66-0.97), with an absolute risk reduction of 0.29% and a number needed to treat of 342 (95% CI, 249-502). No association between the aMED score and total fractures was observed (Q5 HR, 1.01; 95% CI, 0.95-1.07). Higher HEI-2010 or DASH scores tended to be inversely related to hip fracture risk, but the results were nonsignificant (Q5 HR, 0.87; 95% CI, 0.75-1.02; and Q5 HR, 0.89; 95% CI, 0.75-1.06, respectively). The AHEI-2010 score was associated with neither hip nor total fractures.

N° 815 Topic: Vascular Effects of Early versus Late Postmenopausal Treatment with Estradiol
Howard N. Hodis et al report the ¡°Vascular Effects of Early versus Late Postmenopausal Treatment with Estradiol¡±( N Engl J Med 2016; 374:1221-1231March 31, 2016DOI: 10.1056/NEJMoa1505241). A total of 643 healthy postmenopausal women were stratified according to time since menopause (<6 years [early postmenopause] or ¡Ý10 years [late postmenopause]) and were randomly assigned to receive either oral 17ŠÂ-estradiol (1 mg per day, plus progesterone [45 mg] vaginal gel administered sequentially [i.e., once daily for 10 days of each 30-day cycle] for women with a uterus) or placebo (plus sequential placebo vaginal gel for women with a uterus). The primary outcome was the rate of change in carotid-artery intimašCmedia thickness (CIMT), which was measured every 6 months. Secondary outcomes included an assessment of coronary atherosclerosis by cardiac computed tomography (CT), which was performed when participants completed the randomly assigned regimen.
Results: After a median of 5 years, the effect of estradiol, with or without progesterone, on CIMT progression differed between the early and late postmenopause strata (P=0.007 for the interaction). Among women who were less than 6 years past menopause at the time of randomization, the mean CIMT increased by 0.0078 mm per year in the placebo group versus 0.0044 mm per year in the estradiol group (P=0.008). Among women who were 10 or more years past menopause at the time of randomization, the rates of CIMT progression in the placebo and estradiol groups were similar (0.0088 and 0.0100 mm per year, respectively; P=0.29). CT measures of coronary-artery calcium, total stenosis, and plaque did not differ significantly between the placebo group and the estradiol group in either postmenopause stratum.
Conclusions
Oral estradiol therapy was associated with less progression of subclinical atherosclerosis (measured as CIMT) than was placebo when therapy was initiated within 6 years after menopause but not when it was initiated 10 or more years after menopause. Estradiol had no significant effect on cardiac CT measures of atherosclerosis in either postmenopause stratum.



N° 814 Topic: Active commuting and obesity in mid-life: cross-sectional, observational evidence from UK Biobank
E Flint &S Cummins, (Lancet http://dx.doi.org/10.1016/S2213-8587(16)00053-X) examined the relation between active commuting and obesity in mid-life using objectively measured anthropometric data a Cross-sectional, observational study in the UK. Final complete case sample sizes were 72 999 men and 83 667 women for the BMI outcome and 72 139 men and 82 788 women for the percentage body fat outcome. Active commuting was significantly and independently associated with reduced BMI and percentage body fat for both sexes, with a graded pattern apparent across the seven commuting categories. In fully adjusted models, compared with their car-only counterparts, mixed public and active transport commuters had significantly lower BMI and lower percentage body fat.
 These findings support the case for interventions to promote active travel as a population-level policy response for prevention of obesity in mid-life.


N° 813 Topic: A Randomized Trial of a Cervical Pessary to Prevent Preterm Singleton Birth
Kypros H. Nicolaides, et al (N Engl J Med 2016; 374:1044-1052March 17, 2016DOI: 10.1056/NEJMoa1511014) conducted a multicenter, randomized, controlled trial comparing pessary placement with expectant management (control) in girls and women who were pregnant with singletons (singleton pregnancies) and who had a cervical length of 25 mm or less at 20 weeks 0 days to 24 weeks 6 days of gestation. Participants in either group who had a cervical length of 15 mm or less, at randomization or at subsequent visits, received treatment with vaginal progesterone. The primary outcome was spontaneous delivery before 34 weeks of gestation. In an intention-to-treat analysis, there was no significant difference between the pessary group (465 participants) and the control group (467 participants) in the rate of spontaneous delivery before 34 weeks (12.0% and 10.8%, respectively; OR in the pessary group, 1.12; 95%CI, 0.75 to 1.69; P=0.57). There were no significant differences in the rates of perinatal death (3.2% in the pessary group and 2.4% in the control group, P=0.42), adverse neonatal outcome (6.7% and 5.7%, respectively; P=0.55), or neonatal special care (11.6% and 12.9%, respectively; P=0.59). The incidence of new or increased vaginal discharge was significantly higher in the pessary group than in the control group.


N° 812 Topic: A Randomized Trial of a Cervical Pessary to Prevent Preterm Singleton Birth
JoAnn E. Manson and Andrew M. Kaunitz report in a paper entitled “PERSPECTIVE of Menopause Management — Getting Clinical Care Back on Track” (NEJM 3.3.16) that the use of systemic hormone therapy has decreased by as much as 80% among U.S. women since the initial findings of the WHI in 2002, leading to anxiety and confusion. The results of this trial are being used inappropriately in making decisions about treatment for women in their 40s and 50s who have distressing vasomotor symptoms. Moreover, the new generation of medical graduates and primary care providers often lacks training and competence in management of menopausal patients.





N° 811 Topic: The ACOG Committee Opinion about the Use of Vaginal Estrogen in Women With a History of Estrogen-Dependent Breast Cancer
The ACOG Committee Opinion about the Use of Vaginal Estrogen in Women With a History of Estrogen-Dependent Breast Cancer has been published (Obstet Gynecol. 2016 Mar;127(3):e93-6. doi: 10.1097/AOG.0000000000001351.)
They suggest to use first nonhormonal approaches, vaginal estrogen should be reserved for those patients who are unresponsive to nonhormonal remedies. The decision to use vaginal estrogen may be made in coordination with a woman's oncologist. Additionally, it should be preceded by an informed decision-making and consent process in which the woman has the information and resources to consider the benefits and potential risks of low-dose vaginal estrogen.
They write, however, that data do not show an increased risk of cancer recurrence among women currently undergoing treatment for breast cancer or those with a personal history of breast cancer who use vaginal estrogen to relieve urogenital symptoms.

N° 810 Topic: The ACOG Committee Opinion about the Use of Vaginal Estrogen in Women With a History of Estrogen-Dependent Breast Cancer
Vaginal progesterone prophylaxis for preterm birth (the OPPTIMUM study): a multicentre, randomised, double-blind trial
Jane Elizabeth Norman for the OPPTIMUM study group
DOI: http://dx.doi.org/10.1016/S0140-6736(16)00350-0
did a double-blind, randomised, placebo-controlled trial of vaginal progesterone, 200 mg daily taken from 22šC24 to 34 weeks of gestation, on pregnancy and infant outcomes in women at risk of preterm birth (because of previous spontaneous birth at ¡Ü34 weeks and 0 days of gestation, or a cervical length ¡Ü25 mm, or because of a positive fetal fibronectin test combined with other clinical risk factors for preterm birth [any one of a history in a previous pregnancy of preterm birth, second trimester loss, preterm premature fetal membrane rupture, or a history of a cervical procedure to treat abnormal smears]).
The objective of the study was to determine whether vaginal progesterone prophylaxis given to reduce the risk of preterm birth affects neonatal and childhood outcomes.
They randomly assigned 1228 women to the placebo group (n=610) and the progesterone group (n=618). After correction for multiple outcomes, progesterone had no significant effect on the primary obstetric outcome (OR adjusted for multiple comparisons  0,86, 95% CI 0,61šC1,22) or neonatal outcome (OR 0,62, 0,38šC1,03), nor on the childhood outcome Maternal or child serious adverse events were reported in 70 (11%) of 610 patients in the placebo group and 59 (10%) of 616 patients in the progesterone group (p=0¡€27).
Interpretation
Vaginal progesterone was not associated with reduced risk of preterm birth or composite neonatal adverse outcomes, and had no long-term benefit or harm on outcomes in children at 2 years of age.


N° 809 Topic: PERSPECTIVE of Menopause Management — Getting Clinical Care Back on Track
Jiangrong Wang, et al (BMJ 2016; 352 doi: http://dx.doi.org/10.1136/bmj.i276 (Published 11 February 2016) Cite this as: BMJ 2016;352:i276) investigated the risks of invasive cervical cancer after detection of atypical glandular cells (AGC) during cervical screening using a Nationwide population based cohort study in Sweden between 1 January 1980 and 1 July 2011 who had any record of cervical cytological testing at ages 23-59. They found that the prevalence of cervical cancer was 1.4% for women with AGC, which was lower than for women with HSIL (2.5%) but higher than for women with LSIL (0.2%); adenocarcinoma accounted for 73.2% of the prevalent cases associated with AGC. The incidence rate of invasive cervical cancer after AGC was significantly higher than for women with normal results on cytology for up to 15.5 years and higher than HSIL and LSIL for up to 6.5 years. The incidence rate of adenocarcinoma was 61 times higher than for women with normal results on cytology in the first screening round after AGC, and remained nine times higher for up to 15.5 years. Incidence and prevalence of invasive cervical cancer was highest when AGC was found at ages 30-39. Only 54% of women with AGC underwent histology assessment within six months, much less than after HSIL (86%). Among women with histology assessment within six months, the incidence rate of cervical cancer after AGC was significantly higher than that after HSIL for up to 6.5 years.
Conclusions AGC found at cervical screening is associated with a high and persistent risk of cervical cancer for up to 15 years, particularly for cervical adenocarcinoma and women with AGC at age 30-39. Compared with the reduction in risk of cancer seen after HSIL management, management of AGC seems to have been suboptimal in preventing cervical cancer. Research to optimise management is needed, and a more aggressive assessment strategy is warranted.

N° 808 Topic: Predicting the risk of malignancy in adnexal masses based on the Simple Rules from the International Ovarian Tumor Analysis (IOTA) group
Accurate methods to preoperatively characterize adnexal tumors are pivotal for optimal patient management. A recent meta-analysis concluded that the International Ovarian Tumor Analysis (IOTA) algorithms such as the Simple Rules are the best approaches to preoperatively classify adnexal masses as benign or malignant.
Dirk Timmerman et al (2016) (DOI: http://dx.doi.org/10.1016/j.ajog.2016.01.007 article in press) developed and validated a model to predict the risk of malignancy in adnexal masses using the ultrasound features in the Simple Rules using International cross-sectional cohort study involving 22 oncology centers, They included consecutive patients with an adnexal tumor who underwent a standardized transvaginal ultrasound examination and were selected for surgery. Data on 5020 patients were recorded in three phases between 2002 and 2012. The five Simple Rules features indicative of a benign tumor (B-features) and the five features indicative of malignancy (M-features) are based on the presence of ascites, tumor morphology, and degree of vascularity at ultrasonography. Gold standard was the histopathologic diagnosis of the adnexal mass (pathologist blinded to ultrasound findings). Logistic regression analysis was used to estimate the risk of malignancy based on the ten ultrasound features and type of center. The diagnostic performance was evaluated by area under the receiver operating characteristic curve (AUC), sensitivity, specificity, positive and negative likelihood ratios (LR+, LR-), positive and negative predictive values (PPV, NPV) and calibration curves.
Results
Data on 4848 patients were analyzed. The malignancy rate was 43% (1402/3263) in oncology centers and 17% (263/1585) in other centers. The AUC on validation data was very similar in oncology centers (0.917, 95% CI 0.901 to 0.931) and other centers (0.916, 95% CI 0.873 to 0.945). Risk estimates showed good calibration. 23% of patients in the validation data set had a very low estimated risk (<1%), 48% had a high estimated risk (≥30%). For the 1% risk cutoff, sensitivity was 99.7%, specificity 33.7%, LR+ 1.5, LR- 0.010, PPV 44.8% and NPV 98.9%. For the 30% risk cutoff, sensitivity was 89.0%, specificity 84.7%, LR+ 5.8, LR- 0.13, PPV 75.4% and NPV 93.9%.
Conclusion
Quantification of the risk of malignancy based on the Simple Rules has good diagnostic performance both in oncology centers and other centers. A simple classification based on these risk estimates may form the basis of a clinical management system. Patients with a high risk may benefit from surgery by a gynecological oncologist, while patients with a lower risk may be managed locally.


N° 807 Topic: A novel intravaginal ring to prevent HIV-1, HSV-2, HPV, and unintended pregnancy.
Ugaonkar SR et al ( J Control Release. 2015 Jun 17;213:57-68. doi: 10.1016/j.jconrel.2015.06.018. [Epub ahead of print]) described a novel core-matrix intravaginal ring (IVR), the MZCL IVR. The results demonstrated proof-of-concept of a novel core-matrix IVR for sustained and simultaneous delivery of diverse molecules for the prevention of HIV, HSV-2 and HPV acquisition, as well as unintended pregnancy.

N° 806 Topic: Metformin versus Placebo in Obese Pregnant Women without Diabetes Mellitus
Argyro Syngelaki, et al (N Engl J Med 2016; 374:434-443February 4, 2016DOI: 10.1056/NEJMoa1509819) randomized in this double-blind, placebo-controlled trial, ipregnant women with a BMI of more than 35 to receive metformin, (3.0 g per day, or placebo (225 women in each group) from 12 to 18 weeks of gestation until delivery. There was no significant between-group difference in the median neonatal birth-weight z score . The median maternal gestational weight gain was lower in the metformin group than in the placebo group (4.6 kg [interquartile range, 1.3 to 7.2] vs. 6.3 kg [interquartile range, 2.9 to 9.2], P<0.001), as was the incidence of preeclampsia (3.0% vs. 11.3%; OR, 0.24; 95%CI, 0.10 to 0.61; P=0.001). The incidence of side effects was higher in the metformin group than in the placebo group. There were no significant between-group differences in the incidence of gestational diabetes, large-for-gestational-age neonates, or adverse neonatal outcomes.
Conclusions
Among women without diabetes who had a BMI of more than 35, the antenatal administration of metformin reduced maternal weight gain but not neonatal birth weight.


N° 805 Topic: Acupuncture for Menopausal Hot Flashes: A Randomized Trial
Carolyn Ee, et al (Ann Intern Med. Published online 19 January 2016 doi:10.7326/M15-1380) assessed the efficacy of Chinese medicine acupuncture against sham acupuncture for menopausal HFs in a stratified, blind (participants, outcome assessors, and investigators, but not treating acupuncturists), parallel, randomized, sham-controlled trial with equal allocation in women, meeting criteria for Chinese medicine diagnosis of kidney yin deficiency. 327 women older than 40 years in the late menopausal transition or postmenopause with at least 7 moderate HFs daily, were randomly assigned to acupuncture (n = 163) or sham acupuncture (n = 164) and treated for 8 weeks (10 sessions). At the end of treatment, 16% of participants in the acupuncture group and 13% in the sham group were lost to follow-up. Mean HF scores at the end of treatment were 15.36 in the acupuncture group and 15.04 in the sham group (mean difference, 0.33 [95% CI, −1.87 to 2.52]; P = 0.77). No serious adverse events were reported.

Conclusion: Chinese medicine acupuncture was not superior to noninsertive sham acupuncture for women with moderately severe menopausal HFs.

N° 804 Topic: Maternal Immunization With an Investigational Trivalent Group B Streptococcal Vaccine: A Randomized Controlled Trial.

Donders, Gilbert et al (Obstetrics & Gynecology:
Post Author Corrections: January 07, 2016
doi: 10.1097/AOG.0000000000001190) evaluated the safety and immunogenicity of an investigational trivalent group B streptococcal vaccine in pregnant women and antibody transfer to their newborns using an observer-blind, randomized study.

Published Ahead-of-Print

From September 2011 to October 2013, 86 pregnant women were allocated in a 3:2 ratio to receive an investigational group B streptococcal vaccine containing glycoconjugates of serotypes Ia, Ib, and III or placebo. Demographics were similar across groups. Transfer ratios were 66-79% and maternal geometric mean concentrations increased 16-, 23-, and 20-fold by delivery against serotypes Ia, Ib, and III, respectively, Women with no detectable antibodies at inclusion had lower responses than those with detectable antibodies. Three months after birth, infant antibody concentrations were 22-25% of birth levels. Antidiphtheria geometric mean concentrations were similar across groups. In the vaccine and placebo groups, 32 of 51 women (63%) and 26 of 35 women (74%) reported adverse effects, respectively.

CONCLUSION: The investigational vaccine was well-tolerated without safety signals in recipients and their infants or interference with routine infant diphtheria vaccination, although further studies on safety and effectiveness are needed. The investigational vaccine was immunogenic for all serotypes, particularly among women with detectable antibody levels at baseline. Antibody transfer to neonates was at similar levels to other maternally administered polysaccharide vaccines.

N° 803 Topic: Predictive Value of the sFlt-1:PlGF Ratio in Women with Suspected Preeclampsia
The ratio of soluble fms-like tyrosine kinase 1 (sFlt-1) to placental growth factor (PlGF) is elevated in pregnant women before the clinical onset of preeclampsia, but its predictive value in women with suspected preeclampsia is unclear.

Harald Zeisler, et al (N Engl J Med 2016; 374:13-22January 7, 2016DOI: 10.1056/NEJMoa1414838) performed a prospective, multicenter, observational study to derive and validate a ratio of serum sFlt-1 to PlGF that would be predictive of the absence or presence of preeclampsia in the short term in women with singleton pregnancies in whom preeclampsia was suspected (24 weeks 0 days - 36 weeks 6 days).

In the development cohort (500 women), theyidentified an sFlt-1:PlGF ratio cutoff of 38 as having important predictive value. In a subsequent validation study among an additional 550 women, an sFlt-1:PlGF ratio of 38 or lower had a negative predictive value (i.e., no preeclampsia in the subsequent week) of 99.3% (95%CI, 97.9-99.9), with 80.0% sensitivity (95% CI, 51.9- 95.7) and 78.3% specificity (95% CI, 74.6- 81.7). The positive predictive value of an sFlt-1:PlGF ratio above 38 for a diagnosis of preeclampsia within 4 weeks was 36.7% (95% CI, 28.4 to 45.7), with 66.2% sensitivity (95% CI, 54.0 to 77.0) and 83.1% specificity (95% CI, 79.4 to 86.3).

Conclusions

An sFlt-1:PlGF ratio of 38 or lower can be used to predict the short-term absence of preeclampsia in women in whom the syndrome is suspected clinically.

N° 802 Topic: Association Between Use of Oral Fluconazole During Pregnancy and Risk of Spontaneous Abortion and Stillbirth
Ditte Mølgaard-Nielsen, et al (JAMA. 2016;315(1):58-67. doi:10.1001/jama.2015.17844) studied the association between oral fluconazole exposure during pregnancy and the risk of spontaneous abortion and stillbirth using nationwide register-based cohort in Denmark (n=1 405 663 pregnancies), oral fluconazole–exposed pregnancies were compared with up to 4 unexposed pregnancies matched on propensity score, maternal age, calendar year, and gestational age (based on gestational age at first day of treatment with eligible controls surviving through this date). To test for confounding by indication, pregnancies exposed to intravaginal formulations of topical azoles were used as an additional comparator group. Among 3315 women exposed to oral fluconazole from 7 through 22 weeks’ gestation, 147 experienced a spontaneous abortion, compared with 563 among 13 246 unexposed matched women. There was a significantly increased risk of spontaneous abortion associated with fluconazole exposure (HR, 1.48; 95% CI, 1.23-1.77). Among 5382 women exposed to fluconazole from gestational week 7 to birth, 21 experienced a stillbirth, compared with 77 among 21 506 unexposed matched women. There was no significant association between fluconazole exposure and stillbirth (HR, 1.32 [95% CI, 0.82-2.14]). Using topical azole exposure as the comparison, 130 of 2823 women exposed to fluconazole vs 118 of 2823 exposed to topical azoles had a spontaneous abortion (HR, 1.62 [95% CI, 1.26-2.07]); 20 of 4301 women exposed to fluconazole vs 22 of 4301 exposed to topical azoles had a stillbirth (HR, 1.18 [95% CI, 0.64-2.16]).
Conclusions and Relevance In this nationwide cohort study in Denmark, use of oral fluconazole in pregnancy was associated with a statistically significant increased risk of spontaneous abortion compared with risk among unexposed women and women with topical azole exposure in pregnancy. Until more data on the association are available, cautious prescribing of fluconazole in pregnancy may be advisable. Although the risk of stillbirth was not significantly increased, this outcome should be investigated further.

N° 801 Topic: Ovarian Suppression With Triptorelin During Adjuvant Breast Cancer Chemotherapy and Long-term Ovarian Function, Pregnancies, and Disease-Free Survival: A RCT
Matteo Lambertini, et al; for the GIM Study Group (JAMA. 2015;314(24):2632-2640. doi:10.1001/jama.2015.17291) evaluated long-term results of LHRHa-induced ovarian suppression during breast cancer chemotherapy in premenopausal women with stage I to III hormone receptor–positive or hormone receptor–negative breast cancer . Patients were randomized to receive adjuvant or neoadjuvant chemotherapy alone (control group) or chemotherapy plus triptorelin (LHRHa group).
A total of 281 women (median age, 39 [range, 24-45] years) were randomized. Median follow-up was 7.3 years (interquartile range, 6.3-8.2 years). The 5-year cumulative incidence estimate of menstrual resumption was 72.6% (95% CI, 65.7%-80.3%) among the 148 patients in the LHRHa group and 64.0% (95% CI, 56.2%-72.8%) among the 133 patients in the control group (hazard ratio [HR], 1.28 [95% CI, 0.98-1.68]; P = .07; age-adjusted HR, 1.48 [95% CI, 1.12-1.95]; P = .006). Eight pregnancies (5-year cumulative incidence estimate of pregnancy, 2.1% [95% CI, 0.7%-6.3%]) occurred in the LHRHa group and 3 (5-year cumulative incidence estimate of pregnancy, 1.6% [95% CI, 0.4%-6.2%]) in the control group (HR, 2.56 [95% CI, 0.68-9.60]; P = .14; age-adjusted HR, 2.40 [95% CI, 0.62-9.22]; P = .20). Five-year DFS was 80.5% (95% CI, 73.1%-86.1%) in the LHRHa group and 83.7% (95% CI, 76.1%-89.1%) in the control group (LHRHa vs control: HR, 1.17 [95% CI, 0.72-1.92]; P = .52).

Conclusions and Relevance Among premenopausal women with either hormone receptor–positive or hormone receptor–negative breast cancer, concurrent administration of triptorelin and chemotherapy, compared with chemotherapy alone, was associated with higher long-term probability of ovarian function recovery, without a statistically significant difference in pregnancy rate. There was no statistically significant difference in DFS for women assigned to triptorelin and those assigned to chemotherapy alone, although study power was limited.


N° 800 Topic: Azithromycin versus Doxycycline for Urogenital Chlamydia trachomatis Infection
William M. Geisler et al N Engl J Med 2015; 373:2512-2521December 24, 2015DOI: 10.1056/NEJMoa1502599

Urogenital Chlamydia trachomatis infection remains prevalent and causes substantial reproductive morbidity. Recent studies have raised concern about the efficacy of azithromycin for the treatment of chlamydia infection.

The authors conducted a RCT (n=567) using oral azithromycin vs doxycycline for the treatment of urogenital chlamydia infection among adolescents in youth correctional facilities, to evaluate the noninferiority of azithromycin (1 g in one dose) to doxycycline (100 mg twice daily for 7 days). The primary end point was treatment failure at 28 days after treatment initiation, with treatment failure determined on the basis of nucleic acid amplification testing, sexual history, and outer membrane protein A (OmpA) genotyping of C. trachomatis strains.

There were no treatment failures in the doxycycline group. In the azithromycin group, treatment failure occurred in 5 participants (3.2%; 95% CI, 0.4 - 7.4%). The observed difference in failure rates between the treatment groups was 3.2 % points, with an upper boundary of the 90%CI of 5.9 % points, which exceeded the prespecified absolute 5-%-point cutoff for establishing the noninferiority of azithromycin.

Conclusions
In the context of a closed population receiving directly observed treatment for urogenital chlamydia infection, the efficacy of azithromycin was 97%, and the efficacy of doxycycline was 100%. The noninferiority of azithromycin was not established in this setting.


N° 799 Topic: Ovarian cancer screening and mortality in the UK Collaborative Trial of Ovarian Cancer Screening (UKCTOCS): a randomised controlled trial
Prof Ian J Jacobs et al (Lancet Published Online: 17 December 2015) designed a trial (n=202 638) women to establish the effect of early detection by screening on ovarian cancer mortality. Exclusion criteria were previous bilateral oophorectomy or ovarian malignancy, increased risk of familial ovarian cancer, and active non-ovarian malignancy. The RCT randomly allocated participants to annual multimodal screening (MMS) (n=50 640; 25·0%) with serum CA125 interpreted with use of the risk of ovarian cancer algorithm, annual transvaginal ultrasound screening (USS, n=50 639; 25·0%)), or no screening, (101 359 ; 50·0%). The primary outcome was death due to ovarian cancer.
they diagnosed ovarian cancer in 1282 (0·6%) women: 338 (0·7%) in the MMS group, 314 (0·6%) in the USS group, and 630 (0·6%) in the no screening group. Of these women, 148 (0·29%) women in the MMS group, 154 (0·30%) in the USS group, and 347 (0·34%) in the no screening group had died of ovarian cancer.
The primary analysis using a Cox proportional hazards model gave a mortality reduction over years 0–14 of 15% (95% CI −3 to 30; p=0·10) with MMS and 11% (−7 to 27; p=0·21) with USS. The Royston-Parmar flexible parametric model showed that in the MMS group, this mortality effect was made up of 8% (−20 to 31) in years 0–7 and 23% (1–46) in years 7–14, and in the USS group, of 2% (−27 to 26) in years 0–7 and 21% (−2 to 42) in years 7–14. A prespecified analysis of death from ovarian cancer of MMS versus no screening with exclusion of prevalent cases showed significantly different death rates (p=0·021), with an overall average mortality reduction of 20% (−2 to 40) and a reduction of 8% (−27 to 43) in years 0–7 and 28% (−3 to 49) in years 7–14 in favour of MMS.
Interpretation
Although the mortality reduction was not significant in the primary analysis, they noted a significant mortality reduction with MMS when prevalent cases were excluded. The authors noted encouraging evidence of a mortality reduction in years 7–14, but further follow-up is needed before firm conclusions can be reached on the efficacy and cost-effectiveness of ovarian cancer screening.


N° 798 Topic: Anastrozole versus tamoxifen for the prevention of locoregional and contralateral breast cancer in postmenopausal women with locally excised ductal carcinoma in situ (IBIS-II DCIS): a double-blind, randomised controlled trial
Third-generation aromatase inhibitors are more effective than tamoxifen for preventing recurrence in postmenopausal women with hormone-receptor-positive invasive breast cancer. However, it is not known whether anastrozole is more effective than tamoxifen for women with hormone-receptor-positive ductal carcinoma in situ (DCIS). JF Forbes et al on behalf of the IBIS-II investigators (Lancet 14.12.15 DOI: http://dx.doi.org/10.1016/S0140-6736(15)01129-0) compared the efficacy of anastrozole with that of tamoxifen in postmenopausal women with hormone-receptor-positive DCIS using a double-blind, multicentre, RCT (n=2980 postmenopausal women. Median follow-up was 7·2 years (IQR 5·6–8·9), and 144 breast cancer recurrences were recorded. There were no statistically significant differences in overall recurrence, deaths, adverse events: the side-effect profiles of the two drugs differed, with more fractures, musculoskeletal events, hypercholesterolaemia, and strokes with anastrozole and more muscle spasm, gynaecological cancers and symptoms, vasomotor symptoms, and deep vein thromboses with tamoxifen.

N° 797 Topic: A Randomized Trial of Progesterone in Women with Recurrent Miscarriages
Arri Coomarasamy et al N Engl J Med 2015; 373:2141-2148November 26, 2015DOI: 10.1056/NEJMoa1504927 conducted a RCT (n=836 women) to investigate whether treatment with progesterone (2 X daily vaginal suppositories 400 mg micronized progesterone vs placebo) would increase the rates of live births and newborn survival among women with unexplained recurrent miscarriage, starting from a time soon after a positive urinary pregnancy test (and no later than 6 weeks of gestation) through 12 weeks of gestation. The primary outcome was live birth after 24 weeks of gestation. In an intention-to-treat analysis, the rate of live births was 65.8% (262 of 398 women) in the progesterone group and 63.3% (271 of 428 women) in the placebo group (RR, 1.04; 95% confidence interval [CI], 0.94 to 1.15; rate difference, 2.5 %; 95% CI, −4.0 to 9.0). There were no significant between-group differences in the rate of adverse events.

Sensitivity and specificity of mammography and adjunctive ultrasonography to screen for breast cancer in the Japan Strategic Anti-cancer Randomized Trial (J-START): a randomised controlled trial (Lancet 4/11/15 http://dx.doi.org/10.1016/S0140-6736(15)00774-6)

Noriaki Ohuchi, et al for the J-START investigator groups investigated the efficacy of adjunctive ultrasonography with
mammography for breast cancer screening in 72 998 young women or women aged 40–49 years at 42 study sites in Japan. Eligible women had no history of any cancer in the previous 5 years and were expected to live for more than 5 years. Participants were randomly assigned in 1:1 ratio to undergo mammography and ultrasonography (intervention group) or mammography alone (control group) twice in 2 years. The primary outcome was sensitivity, specificity, cancer detection rate, and stage distribution at the first round of screening. Analysis was by intention to treat.

Sensitivity was significantly higher in the intervention group than in the control group (91·1%, 95% CI 87·2–95·0 vs 77·0%, 70·3–83·7; p=0·0004), whereas specificity was significantly lower (87·7%, 87·3–88·0 vs 91·4%, 91·1–91·7; p<0·0001). More cancers were detected in the intervention group than in the control group (184 [0·50%] vs 117 [0·32%], p=0·0003) and were more frequently stage 0 and I (144 [71·3%] vs 79 [52·0%], p=0·0194). 18 (0·05%) interval cancers were detected in the intervention group compared with 35 (0·10%) in the control group (p=0·034).

Interpretation
Adjunctive ultrasonography increases sensitivity and detection rate of early cancers.


N° 795 Topic: Breast Cancer
Prospective Validation of a 21-Gene Expression Assay in Breast Cancer
Joseph A. Sparano et al (NEJM September 28, 2015DOI: 10.1056/NEJMoa1510764) performed a prospective trial involving women with hormone-receptor–positive, human epidermal growth factor receptor type 2 (HER2)–negative, axillary node–negative breast cancer with tumors of 1.1 to 5.0 cm in the greatest dimension (or 0.6 to 1.0 cm in the greatest dimension and intermediate or high tumor grade) who met established guidelines for the consideration of adjuvant chemotherapy on the basis of clinicopathologic features. A reverse-transcriptase–polymerase-chain-reaction assay of 21 genes was performed on the paraffin-embedded tumor tissue, and the results were used to calculate a score indicating the risk of breast-cancer recurrence; patients were assigned to receive endocrine therapy without chemotherapy if they had a recurrence score of 0 to 10, indicating a very low risk of recurrence (on a scale of 0 to 100, with higher scores indicating a greater risk of recurrence).

Of the 10,253 eligible women enrolled, 1626 women (15.9%) who had a recurrence score of 0 to 10 were assigned to receive endocrine therapy alone without chemotherapy. At 5 years, in this patient population, the rate of invasive disease–free survival was 93.8% (95% CI, 92.4 - 94.9), the rate of freedom from recurrence of breast cancer at a distant site was 99.3% (95% CI, 98.7 - 99.6), the rate of freedom from recurrence of breast cancer at a distant or local–regional site was 98.7% (95% CI, 97.9 - 99.2), and the rate of overall survival was 98.0% (95% CI, 97.1 - 98.6).
Conclusions

Among patients with hormone-receptor–positive, HER2-negative, axillary node–negative breast cancer who met established guidelines for the recommendation of adjuvant chemotherapy on the basis of clinicopathologic features, those with tumors that had a favorable gene-expression profile had very low rates of recurrence at 5 years with endocrine therapy alone.

Frédéric Amant for the International Network on Cancer, Infertility, and Pregnancy (INCIP)( NEJM September 28, 2015DOI: 10.1056/NEJMoa1508913) reported the “Pediatric Outcome after Maternal Cancer Diagnosed during Pregnancy”, a multicenter case–control study, comparing children whose mothers received a diagnosis of cancer during the pregnancy with matched children of women without a cancer diagnosis with a follow up at 18 months, 36 months, or both and a cardiac assessment at 36 months. A total of 129 children (median age, 22 months; range, 12 to 42) whose mother had cancer were compared to the control group. During pregnancy, 96 children (74.4%) were exposed to chemotherapy (alone or in combination with other treatments), 11 (8.5%) to radiotherapy (alone or in combination), 13 (10.1%) to surgery alone, 2 (1.6%) to other drug treatments, and 14 (10.9%) to no treatment. Birth weight was below the 10th percentile in 28 of 127 children (22.0%) in the prenatal-exposure group and in 19 of 125 children (15.2%) in the control group (P=0.16). There was no significant between-group difference in cognitive development on the basis of the Bayley score (P=0.08) or in subgroup analyses. The gestational age at birth was correlated with the cognitive outcome in the two study groups. Cardiologic evaluation among 47 children at 36 months of age showed normal cardiac findings.

The authors concluded that Prenatal exposure to maternal cancer with or without treatment did not impair the cognitive, cardiac, or general development of children in early childhood. Prematurity was correlated with a worse cognitive outcome, but this effect was independent of cancer treatment.

Internal Mammary and Medial Supraclavicular Irradiation in Breast Cancer. Poortmans PM et al (N Engl J Med. 2015 Jul 23;373(4):317-27. doi: 10.1056/NEJMoa1415369.)

The authors randomly assigned women who had a centrally or medially located primary tumor, irrespective of axillary involvement, or an externally located tumor with axillary involvement to undergo either whole-breast or thoracic-wall irradiation in addition to regional nodal irradiation (nodal-irradiation group) or whole-breast or thoracic-wall irradiation alone (control group). The primary end point was overall survival. Secondary end points were the rates of disease-free survival, survival free from distant disease, and death from breast cancer.

A total of 4004 patients underwent randomization. The majority of patients (76.1%) underwent breast-conserving surgery. After mastectomy, 73.4% of the patients in both groups underwent chest-wall irradiation. Nearly all patients with node-positive disease (99.0%) and 66.3% of patients with node-negative disease received adjuvant systemic treatment. At a median follow-up of 10.9 years, 811 patients had died. At 10 years, overall survival was 82.3% in the nodal-irradiation group and 80.7% in the control group (hazard ratio for death with nodal irradiation, 0.87; 95% confidence interval [CI], 0.76 to 1.00; P=0.06).

The rate of disease-free survival was 72.1% in the nodal-irradiation group and 69.1% in the control group (hazard ratio for disease progression or death, 0.89; 95% CI, 0.80 to 1.00; P=0.04), the rate of distant disease-free survival was 78.0% versus 75.0% (hazard ratio, 0.86; 95% CI, 0.76 to 0.98; P=0.02), and breast-cancer mortality was 12.5% versus 14.4% (hazard ratio, 0.82; 95% CI, 0.70 to 0.97; P=0.02). Acute side effects of regional nodal irradiation were modest.
CONCLUSIONS:

In patients with early-stage breast cancer, irradiation of the regional nodes had a marginal effect on overall survival. Disease-free survival and distant disease-free survival were improved, and breast-cancer mortality was reduced.

Protecting Ovaries During Chemotherapy Through Gonad Suppression: A Systematic Review and Meta-analysis

Elgindy, et al (Obstetrics and Gynecology July 2015)

estimated whether gonadotropin-releasing hormone (GnRH) analog administration during chemotherapy can protect against development of ovarian toxicity.

Gonadotropin-releasing hormone analog co treatment did not significantly increase ovarian function resumption. No protective effect existed after subgroup analyses (type of malignancy [P=.31], age [P=.14], and GnRH analog type [P=.44]). Gonadotropin-releasing hormone analogs did not protect any of ovarian reserve parameters, whether follicle-stimulating hormone (mean difference −2.63, 95% CI −7.33 to 2.07), antral follicle count (mean difference 1.66, 95% CI −0.69 to 4.01), or anti-Müllerian hormone (mean difference 0.31, 95% CI −0.41 to 1.03). Spontaneous pregnancy was also comparable (risk ratio 1.63, 95% CI 0.94–2.82).

CONCLUSION: Gonadotropin-releasing hormone analog administration during chemotherapy does not appear to protect the ovaries from gonadal toxicity. It is not a reliable method for fertility preservation.

Whole–genome characterization of chemoresistant ovarian cancer

Ann-Marie Patch et al Nature 521,489–494 (28 May 2015) doi:10.1038/nature14410

Patients with high-grade serous ovarian cancer (HGSC) have experienced little improvement in overall survival, and standard treatment has not advanced beyond platinum-based combination chemotherapy, during the past 30 years. To understand the drivers of clinical phenotypes better, the authors used whole-genome sequencing of tumour and germline DNA samples from 92 patients with primary refractory, resistant, sensitive and matched acquired resistant disease. They observed that gene breakage commonly inactivates the tumour suppressors RB1, NF1, RAD51B and PTEN in HGSC, and contributes to acquired chemotherapy resistance. CCNE1 amplification was common in primary resistant and refractory disease. They observed several molecular events associated with acquired resistance, including multiple independent reversions of germline BRCA1 or BRCA2mutations in individual patients, loss of BRCA1 promoter methylation, an alteration in molecular subtype, and recurrent promoter fusion associated with overexpression of the drug efflux pump MDR1.

EvideSubclinical Thyroid Dysfunction and Fracture RiskA Meta-analysis

Manuel R. Blum et al (; for the Thyroid Studies Collaboration JAMA. 2015;313(20):2055-2065. doi:10.1001/jama.2015.5161) assed the association of subclinical thyroid dysfunction with hip, nonspine, spine, or any fractures using a Meta-analysis. Individual participant data were obtained from 13 prospective cohorts.
Among 70 298 participants, 4092 (5.8%) had subclinical hypothyroidism and 2219 (3.2%) had subclinical hyperthyroidism. During 762 401 person-years of follow-up, hip fracture occurred in 2975 participants (4.6%; 12 studies), any fracture in 2528 participants (9.0%; 8 studies), nonspine fracture in 2018 participants (8.4%; 8 studies), and spine fracture in 296 participants (1.3%; 6 studies).

In age- and sex-adjusted analyses, the hazard ratio (HR) for subclinical hyperthyroidism vs euthyroidism was 1.36 for hip fracture (95% CI, 1.13-1.64); for any fracture, HR was 1.28 (95% CI, 1.06-1.53); for nonspine fracture, HR was 1.16 (95% CI, 0.95-1.41); and for spine fracture, HR was 1.51 (95% CI, 0.93-2.45).

Lower TSH was associated with higher fracture rates: for TSH of less than 0.10 mIU/L, HR was 1.61 for hip fracture (95% CI, 1.21-2.15); for any fracture, HR was 1.98 (95% CI, 1.41-2.7); for nonspine fracture, HR was 1.61 (95% CI, 0.96-2.71); and for spine fracture, HR was 3.57 (95% CI, 1.88-6.78).

Endogenous subclinical hyperthyroidism (excluding thyroid medication users) was associated with HRs of 1.52 (95% CI, 1.19-1.93) for hip fracture, 1.42 (95% CI, 1.16-1.74) for any fracture, and 1.74 (95% CI, 1.01-2.99) for spine fracture. No association was found between subclinical hypothyroidism and fracture risk.

Conclusions and Relevance Subclinical hyperthyroidism was associated with an increased risk of hip and other fractures, particularly among those with TSH levels of less than 0.10 mIU/L and those with endogenous subclinical hyperthyroidism. Further study is needed to determine whether treating subclinical hyperthyroidism can prevent fractures.

Palbociclib in Hormone-Receptor–Positive Advanced Breast Cancer
Growth of hormone-receptor–positive breast cancer is dependent on cyclin-dependent kinases 4 and 6 (CDK4 and CDK6), which promote progression from the G1 phase to the S phase of the cell cycle.
Nicholas C. Turner, et al ( NEJM 1.6.15) reported the efficacy of palbociclib (an inhibitor of CDK4 and CDK6) and fulvestrant in advanced breast cancer during a phase 3 study (n=521 patients with advanced hormone-receptor–positive, human epidermal growth factor receptor 2–negative breast cancer) that had relapsed or progressed during prior endocrine therapy.
Patients were treated in a 2:1 ratio with palbociclib and fulvestrant or placebo and fulvestrant. Premenopausal or perimenopausal women also received goserelin.
The median progression-free survival was 9.2 months (95% [CI], 7.5 to not estimable) with palbociclib–fulvestrant and 3.8 months (95% CI, 3.5 to 5.5) with placebo–fulvestrant (HR for disease progression or death, 0.42; 95% CI, 0.32 to 0.56; P 0.42; 95% CI, 0.32 to 0.56).
The most common grade 3 or 4 adverse events in the palbociclib–fulvestrant group were neutropenia (62.0%, vs. 0.6% in the placebo–fulvestrant group), leukopenia (25.2% vs. 0.6%), anemia (2.6% vs. 1.7%), thrombocytopenia (2.3% vs. 0%), and fatigue (2.0% vs. 1.2%). Febrile neutropenia was reported in 0.6% of palbociclib-treated patients and 0.6% of placebo-treated patients. The rate of discontinuation due to adverse events was 2.6% with palbociclib and 1.7% with placebo. CONCLUSIONS Among patients with hormone-receptor–positive metastatic breast cancer who had progression of disease during prior endocrine therapy, palbociclib combined with fulvestrant resulted in longer progression-free survival than fulvestrant alone.

Llarena, Natalia C. et al Obstetrics & Gynecology:
June 2015 - Volume 125 - Issue 6 - p 1407–1417 evaluated the incidence of bowel injury in gynecologic laparoscopy and determined the presentation, mortality, cause, and location of injury within the gastrointestinal tract using a systematic review.
Ninety studies published between 1972 and 2014 met eligibility criteria, representing 474,063 gynecologic laparoscopies. Six hundred four bowel injuries were reported for an incidence of 1 in 769 (0.13%, 95% [CI] 0.12–0.14%). The rate of bowel injury varied by procedure, ranging from 1 in 3,333 (0.03%, 95% CI 0.01–0.03%) for sterilization to 1 in 256 (0.39%, 95% CI 0.34–0.45%) for hysterectomy. The small intestine was the most frequently damaged region of the gastrointestinal tract, representing 166 of 354 (47%) injuries. The majority of bowel injuries occurred during abdominal access and insufflation obtained using a Veress needle or trocar placement (201/366, 55% of injuries). Although most bowel injuries were recognized intraoperatively, diagnosis was delayed by more than 1 day in 154 of 375 cases (41%, 95% CI 36–46%). Bowel injuries were managed primarily by laparotomy (80%). Mortality occurred after bowel injury in 5 of 604, or 1 of 125 (0.8%, 95% CI 0.36–1.9%) cases. All deaths occurred as a result of delayed recognition of bowel injury (n=154), making the mortality rate for unrecognized bowel injury 5 in 154 or 1 in 31 (3.2%, 95% CI 1–7%). There were no deaths associated with intraoperatively diagnosed bowel injury.

Innovative Technique for Enclosed Morcellation Using a Surgical Glove

Akdemir, Ali et al (Obstetrics and Gynecology May 2015)

described an innovative approach for enclosed morcellation using a surgical glove in multiport laparoscopic surgery.

METHODS: Power morcellation was performed within an insufflated surgical glove in a completely enclosed manner between January and May 2014. The specimen was placed into the glove within the abdomen. The glove opening and thumb were exteriorized through the umbilical and left lower abdominal trocar incisions, respectively. The optical trocar and optic were inserted into the glove, which was then insufflated. The thumb tip was cut, and a power morcellator was inserted through this finger. The morcellation was accomplished within the completely enclosed glove. The thumb tip was closed, and the glove, containing residual specimens and bloody fluid, was removed from the abdomen through the umbilical incision. Thus, the risks of bag piercing and leakage during contained power morcellation were eliminated. Demographic and operative data were collected and analyzed for all cases.

RESULTS: Thirty multiport laparoscopic myomectomy and morcellation procedures were performed during the study period. The median operative time was 85 minutes (range 60–140 minutes). The median morcellation preparation time, total morcellation time, and withdrawal time were 6 (range 4.5–14), 32 (range 15–55), and 1.2 (range 1–1.5) minutes, respectively. No intraoperative complications or bag ruptures were recorded.

February 13, 2015 http://dx.doi.org/10.1016/ S0140-6736(14)61687-1) assessed the effects of hormone therapy on ovarian cancer risk using Individual participant datasets from 52 epidemiological studies. During prospective follow-up, 12 110 postmenopausal women, 55% (6601) of whom had used hormone
therapy, developed ovarian cancer. Among women last recorded as current users, risk was increased even with <5 yearsof use (RR 1·43, 95% CI 1·31–1·56; p<0·0001). Combining current-or-recent use (any duration, but stopped<5 years before diagnosis) resulted in an RR of 1·37 (95% CI 1·29–1·46; p<0·0001);
Women who use hormone therapy for 5 years from around age 50 years have about one extra ovarian cancer per 1000 users.

Duration of Menopausal Vasomotor Symptoms Over the Menopause Transition ONLINE FIRST
Nancy E. Avis, et al ; for the Study of Women’s Health Across the Nation (SWAN) (JAMA Intern Med. Published online February 16, 2015. doi:10.1001/jamainternmed.2014.8063 ) determined total duration of frequent menopausal vasomotor symptoms (VMS) (≥6 days in the previous 2 weeks) (hereafter total VMS duration) during the menopausal transition, to quantify how long frequent VMS persist after the final menstrual period (FMP) (hereafter post-FMP persistence), and to identify risk factors for longer total VMS duration and longer post-FMP persistence. They used the The Study of Women’s Health Across the Nation (SWAN), a multiracial/multiethnic observational study of the menopausal transition among 3302 women enrolled (from February 1996 -April 2013). Analyses included 1449 women with frequent VMS.
The median total VMS duration was 7.4 years. Among 881 women who experienced an observable FMP, the median post-FMP persistence was 4.5 years. Women who were premenopausal or early perimenopausal when they first reported frequent VMS had the longest total VMS duration (median, >11.8 years) and post-FMP persistence (median, 9.4 years). Women who were postmenopausal at the onset of VMS had the shortest total VMS duration (median, 3.4 years). Compared with women of other racial/ethnic groups, African American women reported the longest total VMS duration (median, 10.1 years). Additional factors related to longer duration of VMS (total VMS duration or post-FMP persistence) were younger age, lower educational level, greater perceived stress and symptom sensitivity, and higher depressive symptoms and anxiety at first report of VMS.
Conclusions and Relevance Frequent VMS lasted more than 7 years during the menopausal transition for more than half of the women and persisted for 4.5 years after the FMP. Individual characteristics (eg, being premenopausal and having greater negative affective factors when first experiencing VMS) were related to longer-lasting VMS. Health care professionals should counsel women to expect that frequent VMS could last more than 7 years, and they may last longer for African American women.

Association Between Sauna Bathing and Fatal Cardiovascular and All-Cause Mortality Events ONLINE FIRST
Tanjaniina Laukkanen, et al (JAMA Intern Med. Published online February 23, 2015. doi:10.1001/jamainternmed.2014.8187 ) investigated the association of frequency and duration of sauna bathing with the risk of sudden cardiac death (SCD), fatal coronary heart disease (CHD), fatal cardiovascular disease (CVD), and all-cause mortality using a prospective cohort study (Finnish Kuopio Ischemic Heart Disease Risk Factor Study) of a population-based sample of 2315 middle-aged (age range, 42-60 years) men from Eastern Finland. Baseline examinations were conducted from March 1, 1984, through December 31, 1989.
During a median follow-up of 20.7 years, 190 SCDs, 281 fatal CHDs, 407 fatal CVDs, and 929 all-cause mortality events occurred. A total of 601, 1513, and 201 participants reported having a sauna bathing session 1 time per week, 2 to 3 times per week, and 4 to 7 times per week, respectively. After adjustment for CVD risk factors, compared with men with 1 sauna bathing session per week, the hazard ratio of SCD was 0.78 (95% CI, 0.57-1.07) for 2 to 3 sauna bathing sessions per week and 0.37 (95% CI, 0.18-0.75) for 4- 7 sauna bathing sessions per week (P for trend = .005). Similar associations were found with CHD, CVD, and all-cause mortality (P for trend ≤.005). Compared with men having a sauna bathing session of less than 11 minutes, the adjusted hazard ratio for SCD was 0.93 (95% CI, 0.67-1.28) for sauna bathing sessions of 11 to 19 minutes and 0.48 (95% CI, 0.31-0.75) for sessions lasting more than 19 minutes (P for trend = .002); significant inverse associations were also observed for fatal CHDs and fatal CVDs (P for trend ≤.03) but not for all-cause mortality events.
Conclusions and Relevance Increased frequency of sauna bathing is associated with a reduced risk of SCD, CHD, CVD, and all-cause mortality. Further studies are warranted to establish the potential mechanism that links sauna bathing and cardiovascular health.

G Protein-coupled Estrogen Receptor Protects from Atherosclerosis
Matthias R. Meyer et al (Scientific Reports 4, Article number: 7564 doi:10.1038/srep07564)

Coronary atherosclerosis and myocardial infarction in postmenopausal women have been linked to inflammation and reduced nitric oxide (NO) formation. Natural estrogen exerts protective effects on both processes, yet also displays uterotrophic activity. Here, we used genetic and pharmacologic approaches to investigate the role of the G protein-coupled estrogen receptor (GPER) in atherosclerosis. In ovary-intact mice, deletion of gper increased atherosclerosis progression, total and LDL cholesterol levels and inflammation while reducing vascular NO bioactivity, effects that were in some cases aggravated by surgical menopause. In human endothelial cells, GPER was expressed on intracellular membranes and mediated eNOS activation and NO formation, partially accounting for estrogen-mediated effects. Chronic treatment with G-1, a synthetic, highly selective small molecule agonist of GPER, reduced postmenopausal atherosclerosis and inflammation without uterotrophic effects. In summary, this study reveals an atheroprotective function of GPER and introduces selective GPER activation as a novel therapeutic approach to inhibit postmenopausal atherosclerosis and inflammation in the absence of uterotrophic activity.

A Clinical Trial of Progesterone for Severe Traumatic Brain Injury
Brett E. Skolnick, et al. for the SYNAPSE Trial Investigators (NEJM December 10, 2014DOI: 10.1056/NEJMoa1411090)

Progesterone has been associated with positive effects in animal models of traumatic brain injury (TBI) and with clinical benefits in two phase 2 randomized, controlled trials. The authors investigated the efficacy and safety of progesterone in a large, prospective, phase 3 randomized clinical trial.
Proportional-odds analysis with covariate adjustment showed no treatment effect of progesterone as compared with placebo (odds ratio, 0.96; confidence interval, 0.77 to 1.18). The proportion of patients with a favorable outcome on the Glasgow Outcome Scale (good recovery or moderate disability) was 50.4% with progesterone, as compared with 50.5% with placebo. Mortality was similar in the two groups. No relevant safety differences were noted between progesterone and placebo.


N° 777 Topic: Breast Cancer
Adjuvant Ovarian Suppression in Premenopausal Breast Cancer
Prudence A. Francis, for the SOFT Investigators and the International Breast Cancer Study Group (NEJM December 11, 2014DOI: 10.1056/NEJMoa1412379) randomly assigned 3066 premenopausal women, stratified according to prior receipt or nonreceipt of chemotherapy, to receive 5 years of tamoxifen, tamoxifen plus ovarian suppression, or exemestane plus ovarian suppression. The primary analysis tested the hypothesis that tamoxifen plus ovarian suppression would improve disease-free survival, as compared with tamoxifen alone. In the primary analysis, 46.7% of the patients had not received chemotherapy previously, and 53.3% had received chemotherapy and remained premenopausal. After a median follow-up of 67 months, the estimated disease-free survival rate at 5 years was 86.6% in the tamoxifen–ovarian suppression group and 84.7% in the tamoxifen group (hazard ratio for disease recurrence, second invasive cancer, or death, 0.83; 95% confidence interval [CI], 0.66 to 1.04; P=0.10). Multivariable allowance for prognostic factors suggested a greater treatment effect with tamoxifen plus ovarian suppression than with tamoxifen alone (hazard ratio, 0.78; 95% CI, 0.62 to 0.98). Most recurrences occurred in patients who had received prior chemotherapy, among whom the rate of freedom from breast cancer at 5 years was 82.5% in the tamoxifen–ovarian suppression group and 78.0% in the tamoxifen group (hazard ratio for recurrence, 0.78; 95% CI, 0.60 to 1.02). At 5 years, the rate of freedom from breast cancer was 85.7% in the exemestane–ovarian suppression group (hazard ratio for recurrence vs. tamoxifen, 0.65; 95% CI, 0.49 to 0.87).

Conclusions
Adding ovarian suppression to tamoxifen did not provide a significant benefit in the overall study population. However, for women who were at sufficient risk for recurrence to warrant adjuvant chemotherapy and who remained premenopausal, the addition of ovarian suppression improved disease outcomes. Further improvement was seen with the use of exemestane plus ovarian suppression.

N° 776 Topic: Statin Therapy and Risk of Fracture: Results From the JUPITER Randomized Clinical Trial
Jessica M. Peña, et al

determined whether statin therapy reduces the risk of fracture and, in a secondary analysis, whether baseline levels of the inflammatory biomarker high-sensitivity C-reactive protein (hs-CRP) are associated with the risk of fracture.The JUPITER (Justification for the Use of Statins in Prevention: an Intervention Trial Evaluating Rosuvastatin) trial was an international, randomized, double-blind, placebo-controlled study enrolling 17 802 men older than 50 years and women older than 60 years with hs-CRP level of at least 2 mg/L. Participants were screened from 2003 to 2006 and observed prospectively for up to 5 years (median follow-up, 1.9 years) and treated with Rosuvastatin calcium, 20 mg daily, or placebo.

During the study, 431 incident fractures were reported and confirmed. Among participants allocated to rosuvastatin, 221 fractures were confirmed, compared with 210 among those allocated to placebo, such that the incidence of fracture in the rosuvastatin and placebo groups was 1.20 and 1.14 per 100 person-years, respectively (adjusted HR, 1.06 [95% CI, 0.88-1.28]; P = .53). Overall, increasing baseline hs-CRP level was not associated with an increased risk of fractures (adjusted HR for each unit increase in hs-CRP tertile, 1.06 [95% CI, 0.94-1.20]; P for trend, .34).

Conclusions and Relevance Among men and women with elevated hs-CRP level enrolled in a large trial of rosuvastatin therapy for cardiovascular disease, statin therapy did not reduce the risk of fracture. Higher baseline hs-CRP level was not associated with an increased risk of incident fracture.

Lipid profiles and ovarian reserve status: a longitudinal study
Fahimeh Ramezani Tehrani et al Hum. Reprod. (2014)
doi: 10.1093/humrep/deu249) analysed the relation between ovarian reserve status and lipid profile changes. A longitudinal study was conducted on 1015 participants of Tehran Lipid and Glucose Study, an ongoing population based cohort study with 12 years follow-up. The ovarian reserve status of 1015 women aged 20-50, was identified according to their age-specific AMH levels, calculated using the exponential–normal 3-parameter model. Total cholesterol (TC) net changes per year were incremental in the first AMH quartile but not in the fourth quartile (P < 0.001). According to the generalized estimating equation (GEE), after adjustment for age, BMI, time interaction and menopause status, the changes across time in TC, LDL and HDL were varied according to the age-specific AMH status.

The authors suggest that women with lower ovarian reserve might be susceptible to developing cardiovascular risk factors, particularly lipid disturbances, even during their reproductive life span.

N° 773 Topic: Obesity and Age at Diagnosis of Endometrial Cancer
Nevadunsky, et al (Obstetrics & Gynecology. 124(2, PART 1):300-306, August 2014.) reported using a retrospective chart review of all cases of endometrial cancer diagnosed from 1999 to 2009 at a large medical center in New York City that the mean age at endometrial cancer diagnosis was 67.1 years (±11.9 SD) in women with a normal BMI, whereas it was 56.3 years (±10.3 SD) in women with a BMI greater than 50. Age at diagnosis of endometrioid-type cancer decreased linearly with increasing BMI. This association persisted after multivariable adjustment (R2=0.181, P<.02). A linear association between BMI and age of nonendometrioid cancers was not found. There were no differences in overall survival by BMI category.

Arterial Imaging Outcomes and Cardiovascular Risk Factors in Recently Menopausal Women: A Randomized Trial Cardiovascular Disease and Menopausal Hormone Therapy

SM Harman, et al (Ann Intern Med. Published online 29 July 2014 doi:10.7326/M14-0353 ) assessed atherosclerosis progression and CVD risk factors after MHT initiated in early menopause using an RCT. Healthy menopausal women aged 42 to 58 years between 6 and 36 months from last menses without prior CVD events who had a coronary artery calcium (CAC) score less than 50 Agatston units and had not received estrogen or lipid-lowering therapy for at least 90 days were treated with oral conjugated equine estrogens (o-CEE), 0.45 mg/d, or transdermal 17β-estradiol (t-E2), 50 mcg/d, each with 200 mg of oral progesterone for 12 days per month, or placebo for 48 months.
Primary end point was annual change in carotid artery intima–media thickness (CIMT). Secondary end points included changes in markers of CVD risk.
Results: Of 727 randomly assigned women, 89.3% had at least 1 follow-up CIMT and 79.8% had CIMT at 48 months. Mean CIMT increases of 0.007 mm/y were similar across groups. The percentages of participants in whom CAC score increased did not differ significantly across groups. No changes in blood pressure were observed with o-CEE or t-E2. Low- and high-density lipoprotein cholesterol levels improved and levels of C-reactive protein and sex hormone–binding globulin but not interleukin-6 increased with o-CEE. Insulin resistance decreased with t-E2. Serious adverse events did not differ by treatment.
Although the power to compare clinical events was insufficient, the authors concluded that 4 years of early MHT did not affect progression of atherosclerosis despite improving some markers of CVD risk.

N° 770 Topic: Breast Cancer : Risk in Families with Mutations in PALM2
AC. Antoniou, et al (N Engl J Med 2014; 371:497-506August 7, 2014DOI: 10.1056/NEJMoa1400382) analyzed the risk of breast cancer among 362 members of 154 families who had deleterious truncating, splice, or deletion mutations in PALB2. The age-specific breast-cancer risk for mutation carriers was estimated with the use of a modified segregation-analysis approach that allowed for the effects of PALB2 genotype and residual familial aggregation.

The risk of breast cancer for female PALB2 mutation carriers, as compared with the general population, was eight to nine times as high among those younger than 40 years of age, six to eight times as high among those 40 to 60 years of age, and five times as high among those older than 60 years of age. The estimated cumulative risk of breast cancer among female mutation carriers was 14% (95% confidence interval [CI], 9 to 20) by 50 years of age and 35% (95% CI, 26 to 46) by 70 years of age. Breast-cancer risk was also significantly influenced by birth cohort (P<0.001) and by other familial factors (P=0.04). The absolute breast-cancer risk for PALB2 female mutation carriers by 70 years of age ranged from 33% (95% CI, 25 to 44) for those with no family history of breast cancer to 58% (95% CI, 50 to 66) for those with two or more first-degree relatives with breast cancer at 50 years of age.

Conclusions

The authors concluded that loss-of-function mutations in PALB2 are an important cause of hereditary breast cancer, with respect both to the frequency of cancer-predisposing mutations and to the risk associated with them. They suggest that the breast-cancer risk for PALB2 mutation carriers may overlap with that for BRCA2 mutation carriers.

Lale Say et al (Lancet Glob Health 2014; 2: e323–33 Published Online May 6, 2014 http://dx.doi.org/10.1016/) developed and analysed global, regional, and subregional estimates of the causes of maternal death during 2003–09, updating the previous WHO systematic review. They identified 23 eligible studies including 417 datasets from 115 countries and comprising 60 799 deaths in the analysis. About 73% of all maternal deaths were due to direct obstetric causes and deaths due to indirect causes accounted for 27·5% of all deaths. Haemorrhage accounted for 27·1%, hypertensive disorders 14·0% , and sepsis 10·7% of maternal deaths. The rest of deaths were due to abortion (7·9%), embolism (3·2%), and all other direct causes of death (9·6%, ). Regional estimates varied substantially.
Interpretation Between 2003 and 2009, haemorrhage, hypertensive disorders, and sepsis were responsible for more than half of maternal deaths worldwide. More than a quarter of deaths were attributable to indirect causes.

In January 2013, the Swiss Medical Board, an independent health technology assessment initiative under the auspices of the Conference of Health Ministers of the Swiss Cantons, the Swiss Medical Association, and the Swiss Academy of Medical Sciences, was mandated to prepare a review of mammography screening.
In February, 2014 (www.medical-board.ch), the board recommended that no new systematic mammography screening programs be introduced and that a time limit be placed on existing programs. In addition, it stipulated that the quality of all forms of mammography screening should be evaluated and that clear and balanced information should be provided to women regarding the benefits and harms of screening.
Two of the participants of that board express their view in a commentary in the latest NEJM issue (Nikola Biller-Andorno, M.D., Ph.D., and Peter Jüni, M.D. N Engl J Med 2014; 370:1965-1967May 22, 2014DOI: 10.1056/NEJMp1401875) (http://www.nejm.org/d oi/pdf/10.1056/NEJMp1401875)

Impact of a premature menopause on cognitive function in later life. Ryan et al (JBJOG. 2014 May 7. doi: 10.1111/1471-0528.12828. ) These authors observed that menopause at or before the age of 40 years, both premature bilateral ovariectomy and premature ovarian failure (non-surgical loss of ovarian function), was associated with worse verbal fluency (OR 1.56, 95%CI 1.12-1.87, P = 0.004) and visual memory (OR 1.39, 95%CI 1.09-1.77, P = 0.007) in later life. HT at the time of premature menopause appeared beneficial for later-life visual memory but increased the risk of poor verbal fluency. Type of menopause was not significantly associated with cognitive function. Premature menopause was associated with a 30% increased risk of decline in psychomotor speed and global cognitive function over 7 years.

The FDA decided, despite a negative vote from an advisory committee, to approve Brisdelle for Menopausal Hot Flushes

First nonhormonal option to women who cannot or do not want to use hormonal medications to treat their menopausal vasomotor symptoms. Brisdelle contains 7.5 mg of paroxetine, a selective serotonin-reuptake inhibitor, and is taken at bedtime. The efficacy of Brisdelle was established in two RCT but shows a modest effect, but clinical relevant, over placebo.

It has a known interaction with tamoxifen use, and it can decrease plasma concentrations of endoxifen. There have been also concerns about suicidal ideation with this class of medication.

McClung, et al (NEJM January 1, 2014DOI: 10.1056/NEJMoa1305224) reported the effect of Romosozumab in Postmenopausal Women with Low Bone Mineral Density. Sclerostin is an osteocyte-derived inhibitor of osteoblast activity. The monoclonal antibody romosozumab binds to sclerostin and increases bone formation. They conducted a phase 2, multicenter, international, RCT over a 12-month period in 419 postmenopausal women, 55 to 85 years of age, who had low bone mineral density. Participants were randomly assigned to receive subcutaneous romosozumab monthly (at a dose of 70 mg, 140 mg, or 210 mg) or every 3 months (140 mg or 210 mg), subcutaneous placebo, or an open-label active comparator — oral alendronate (70 mg weekly) or subcutaneous teriparatide (20 μg daily). The primary end point was the percentage change from baseline in bone mineral density at the lumbar spine at 12 months. Secondary end points included percentage changes in bone mineral density at other sites and in markers of bone turnover. All dose levels of romosozumab were associated with significant increases in bone mineral density at the lumbar spine, including an increase of 11.3% with the 210-mg monthly dose, as compared with a decrease of 0.1% with placebo and increases of 4.1% with alendronate and 7.1% with teriparatide. Romosozumab was also associated with large increases in bone mineral density at the total hip and femoral neck, as well as transitory increases in bone-formation markers and sustained decreases in a bone-resorption marker. Except for mild, generally nonrecurring injection-site reactions with romosozumab, adverse events were similar among groups.

Introduction
Three of the authors are general practitioners who see many patients and couples who lead unnecessarily stressful lives by wanting to be right rather than happy. Mathieu encourages her psychotherapy clients “to try to live in the gray. There are a million shades of gray” (although a recent erotic novel suggests there are only 50) “on the spectrum of white to black, and each provides a much richer telling of a story that is hardly ever as clear as this or that. So, when we looked a bit more closely, we saw that ‘right versus happy’ was not so much about getting crowned the winner or loser, a genius or fool; it was more about flawed thinking and a desire to want to feel being in control.”1 This might be the first study to systematically assess whether it is better to be right than happy; a Medline search in May 2013 found no similar articles. Our null hypothesis was that it is better to be right than happy.
Participants, setting, and design
To be eligible participants had to be part of a couple and willing to take part in the study. We carried out a parallel trial with one man and one woman in their own home. It was decided without consultation that the female participant would prefer to be right and the male, being somewhat passive, would prefer to be happy.
The male was informed of the intervention while the female participant was not (this form of pre-randomisation is known as the Zelen method2). The female participant was blind to the hypothesis being tested, other than being asked to record her quality of life.
Intervention
The intervention was for the male to agree with his wife’s every opinion and request without complaint. Even if he believed the female participant was wrong, the male was to bow and scrape.
Main outcome measure
We measured quality of life with a Likert score of 1 to 10 (10 being the best possible quality of life). Although our tool was unvalidated, it was thought to have face validity. It was justified on the grounds that brevity was essential, given that the intervention was administered in a potentially complex domestic environment.
Results
Two participants were eligible and both (100%) were randomised. All participants received the treatment and were analysed for the primary outcome with an intention to treat analysis. Several baseline characteristics differed between the subjects (see appendix).
The data safety monitoring committee stopped the study because of severe adverse outcomes after 12 days. By then the male participant found the female participant to be increasingly critical of everything he did. The situation had become intolerable by day 12. He sat on the end of their bed, made her a cup of tea, and said as much; explained the trial and then contacted the Data Safety Monitoring committee who terminated the trial immediately.
There were three data points in the intervention group and two in the control group (the control participant had become hostile to recording her quality of life).
The man’s quality of life score had fallen from 7 out of 10 at baseline to 3 at 12 days; the women’s had increased slightly from 8 to 8.5 at six days. The difference between the two participants’ QOL scores over time is significantly different (P=0.004, calculated with a repeated measures generalised linear model). We should treat the results cautiously because we cannot discount causes other than treatment reducing the male participant’s score. It seems that being right, however, is a cause of happiness, and agreeing with what one disagrees with is a cause of unhappiness. We cannot discount that the difference in results might be caused by differences between the two treatment groups, which unfortunately we were unable to match by possible confounders such as sex.

Quality of life by duration of intervention
The harms were estimated as 100% as all participants who received the intervention reported a serious adverse event.
Discussion
The results of this trial show that the availability of unbridled power adversely affects the quality of life of those on the receiving end.
Strengths and weaknesses
The study has some limitations. There was no trial registration, no ethics committee approval, no informed consent, no proper randomisation, no validated test instrument, and questionable statistical assessment. We used the eyeball technique for single patient trials which, as Sackett says, “more closely matches the way we think as clinicians.”3
Generalisability
Many people in the world live as couples, and we believe that it could be harmful for one partner to always have to agree with the other. However, more research is needed to see whether our results hold if it is the male who is always right.

Vitamin D status and ill health: a systematic review
Low serum concentrations of 25-hydroxyvitamin D (25[OH]D) have been associated with many non-skeletal disorders. However, whether low 25(OH)D is the cause or result of ill health is not known. Philippe Autier et al (The Lancet Diabetes & Endocrinology, Volume 2, Issue 1, Pages 76 - 89, January 2014 ) conducted a systematic search of prospective and intervention studies that assessed the effect of 25(OH)D concentrations on non-skeletal health outcomes in individuals aged 18 years or older. They identified 290 prospective cohort studies (279 on disease occurrence or mortality, and 11 on cancer characteristics or survival), and 172 randomised trials of major health outcomes and of physiological parameters related to disease risk or inflammatory status. Investigators of most prospective studies reported moderate to strong inverse associations between 25(OH)D concentrations and cardiovascular diseases, serum lipid concentrations, inflammation, glucose metabolism disorders, weight gain, infectious diseases, multiple sclerosis, mood disorders, declining cognitive function, impaired physical functioning, and all-cause mortality. High 25(OH)D concentrations were not associated with a lower risk of cancer, except colorectal cancer.
Results from intervention studies did not show an effect of vitamin D supplementation on disease occurrence, including colorectal cancer. In 34 intervention studies including 2805 individuals with mean 25(OH)D concentration lower than 50 nmol/L at baseline supplementation with 50 μg per day or more did not show better results. Supplementation in elderly people (mainly women) with 20 μg vitamin D per day seemed to slightly reduce all-cause mortality.
The discrepancy between observational and intervention studies suggests that low 25(OH)D is a marker of ill health. Inflammatory processes involved in disease occurrence and clinical course would reduce 25(OH)D, which would explain why low vitamin D status is reported in a wide range of disorders.
In elderly people, restoration of vitamin D deficits due to ageing and lifestyle changes induced by ill health could explain why low-dose supplementation leads to slight gains in survival.

Anastrozole for prevention of breast cancer in high-risk postmenopausal women (IBIS-II): an international, double-blind, randomised placebo-controlled trial
Jack Cuzick, et al on behalf of the IBIS-II investigators (Lancet December 12, 2013) assessed the efficacy and safety of the aromatase inhibitor anastrozole for the prevention of breast cancer in postmenopausal women who are at high risk of the disease, using a double-blind, randomised placebo-controlled trial. 1920 women were randomly assigned to receive anastrozole and 1944 to placebo. After a median follow-up of
5·0 years (IQR 3·0–7·1), 40 women in the anastrozole group (2%) and 85 in the placebo group (4%) had developed breast cancer (HR 0·47, 95% CI 0·32–0·68, p<0·0001). The predicted cumulative incidence of all breast cancers after 7 years was 5·6% in the placebo group and 2·8% in the anastrozole group. 18 deaths were reported in the anastrozole group and 17 in the placebo group, and no specific causes were more common in one group than the other (p=0·836).
Interpretation Anastrozole effectively reduces incidence of breast cancer in high-risk postmenopausal women. This finding, along with the fact that most of the side-effects associated with oestrogen deprivation were not attributable to treatment, provides support for the use of anastrozole in postmenopausal women at high risk of breast cancer.

Guglielmo Ronco et al for the International HPV screening working group analysed Efficacy of HPV-based screening for prevention of invasive cervical cancer using a follow-up of four European randomised controlled trials. The studies involved 176 464 women aged 20—64 years, randomly assigned to HPV-based (experimental arm) or cytology-based (control arm) screening in Sweden (Swedescreen), the Netherlands (POBASCAM), England (ARTISTIC), and Italy (NTCC). The median followed up was 6·5 years (1 214 415 person-years). 107 invasive cervical carcinomas were identified by linkage with screening, pathology, and cancer registries, by masked review of histological specimens, or from reports. Cumulative and study-adjusted rate ratios (experimental vs control) were calculated for incidence of invasive cervical carcinoma. They found that HPV-based screening provides 60—70% greater protection against invasive cervical carcinomas compared with cytology. Data of large-scale randomised trials support initiation of HPV-based screening from age 30 years and extension of screening intervals to at least 5 years.

Benefits and harms of adhesion barriers for abdominal surgery: a systematic review and meta-analysis
Formation of adhesions after peritoneal surgery results in high morbidity. Barriers to prevent adhesion are seldom applied, despite their ability to reduce the severity of adhesion formation.
Findings
This search returned 1840 results, from which 28 trials (5191 patients) were included in the meta-analysis. The risks of systematic and random errors were low. No trials reported data for the effect of oxidised regenerated cellulose or polyethylene glycol on reoperations for adhesive small bowel obstruction. Oxidised regenerated cellulose reduced the incidence of adhesions (relative risk [RR] 0·51, 95% CI 0·31—0·86). Some evidence suggests that hyaluronate carboxymethylcellulose reduces the incidence of reoperations for adhesive small bowel obstruction (RR 0·49, 95% CI 0·28—0·88). For icodextrin, reoperation for adhesive small bowel obstruction did not differ significantly between groups (RR 0·33, 95% CI 0·03—3·11). No barriers were associated with an increase in serious adverse events.
Interpretation
Oxidised regenerated cellulose and hyaluronate carboxymethylcellulose can safely reduce clinically relevant consequences of adhesions.

PLS3 Mutations in X-Linked Osteoporosis with Fractures
Plastin 3 (PLS3), a protein involved in the formation of filamentous actin (F-actin) bundles, appears to be important in human bone health, on the basis of pathogenic variants in PLS3 in five families with X-linked osteoporosis and osteoporotic fractures that we report here. The bone-regulatory properties of PLS3 were supported by in vivo analyses in zebrafish. Furthermore, in an additional five families (described in less detail) referred for diagnosis or ruling out of osteogenesis imperfecta type I, a rare variant (rs140121121) in PLS3 was found. This variant was also associated with a risk of fracture among elderly heterozygous women that was two times as high as that among noncarriers, which indicates that genetic variation in PLS3 is a novel etiologic factor involved in common, multifactorial osteoporosis.

Obstetrics & Gynecology. 122(4):737-744, October 2013) report Effects of Gefitinib, an Epidermal Growth Factor Receptor Inhibitor, on Human Placental Cell Growth. Placenta has the highest expression of epidermal growth factor (EGF) receptor of all tissues, a cell signaling pathway promoting survival and growth. Therefore, EGF receptor inhibition could potentially treat ectopic pregnancy. These authors examined whether gefitinib (orally available EGF receptor inhibitor) with or without methotrexate inhibits placental cell growth. Gefitinib and methotrexate were added to placental cells and their ability inhibit cell growth, block EGF receptor signaling, and induce apoptosis (programmed cell death) was examined. They were also administered to two animal mouse models to examine their effects on placental tissue in vivo. Epidermal growth factor receptor was highly expressed in placental tissue from ectopic pregnancies. Combining gefitinib with methotrexate potently inhibited growth of placental cells, including placental cell lines (JEG3, BeWo cells) and cells isolated from first-trimester placenta. These drugs were additive in blocking EGF receptor signaling and inducing apoptosis. Gefitinib and methotrexate administered together were more potent in decreasing the volume of human placental cells xenografted subcutaneously onto mice compared with either alone. Combining gefitinib with methotrexate potently inhibits placental cell growth in vitro and in mouse models. The combination may have potential in treating ectopic pregnancies.
Skubisz, Monika et al (Obstetrics & Gynecology. 122(4):745-751, October 2013) evaluated Combination Gefitinib and Methotrexate Compared With Methotrexate Alone to Treat Ectopic Pregnancy in a a phase I, single-arm (nonrandomized), open-label study in 12 women with ectopic pregnancies (methotrexate (50 mg/m2,IM) and 250 mg PO gefitinib in a dose-escalation protocol: one dose (day 1) n=3; three doses (days 1–3) n=3; seven doses (days 1–7) n=6. Efficacy was examined by comparing human chorionic gonadotrophin (hCG) decline and time to resolution with historic controls administered methotrexate only. Common side effects were transient acneiform rash in 67% (8/12) and diarrhea in 42% (5/12) of participants. There was no clinical or biochemical evidence of serious pulmonary, renal, hepatic, or hematologic toxicity. Of six participants with a pretreatment serum hCG level between 1,000 and 3,000 international units/L, hCG levels declined significantly faster than in the control group. Median serum hCG levels by day 7 after treatment were less than one fifth of levels observed among 71 historic controls treated with methotrexate alone (median [interquartile range] hCG in participants 261 [55–1,445] international units/L compared with controls 1,426 [940–2,573]; P=.008). Median time for the ectopic pregnancies to resolve with combination therapy was 34% shorter compared with methotrexate alone (21 days compared with 32 days; P=.018). Combination gefitinib and methotrexate has potential as a treatment for ectopic pregnancy but is commonly associated with minor side effects such as transient rash and diarrhea. The treatment requires validation of safety and efficacy in a larger trial.

Leclair, Catherine et al (Obstetrics & Gynecology. 122(4):787-793, October 2013) assessed whether premenopausal and postmenopausal vestibulodynia have different histologic features. They conducted a retrospective analysis of vestibulectomy specimens from 21 women with postmenopausal vestibulodynia and compared them with 88 premenopausal patients (42 primary, 46 secondary).
Seventy-one percent (15/21) of postmenopausal women reported vestibular dyspareunia related to a drop in estrogen either with menopause (13/21) or previously, postpartum (2/21). Eighty-six percent (18/21) of postmenopausal patients were using local or systemic estrogen but pain persisted. Compared with premenopausal primary and secondary vestibular biopsies, postmenopausal tissues had more lymphocytes (unadjusted odds ratio [OR] 9.0, 95% confidence interval [CI] 2.8–33.3; adjusted OR for parity and duration of symptoms 9.1, 95% CI 2.6–31.9; unadjusted OR 6.2, 95% CI 1.9–20.0; adjusted OR 6.6, 95% CI 2.0–21.9, respectively) and mast cells (mean 36 compared with 28 and 36 compared with 26, respectively). There was significantly less neural hyperplasia and progesterone receptor expression in postmenopausal biopsies compared with primary cases but less progesterone receptor and similar neural hyperplasia compared with premenopausal secondary cases. Estrogen receptor α did not vary among groups.
CONCLUSION: Premenopausal and postmenopausal vestibulodynia share histologic features of neurogenic inflammation but differ strikingly in degree. When estrogen supplement does not alleviate symptoms of postmenopausal dyspareunia, vestibulodynia should be considered.

Ju-Sheng Zheng, et al (BMJ 2013;346:f3706 ) investigated the association between intake of fish and n-3 polyunsaturated fatty acids (n-3 PUFA) and the risk of breast cancer using a meta-analysis and systematic review of prospective cohort studies.
Marine n-3 PUFA was associated with 14% reduction of risk of breast cancer (RR for highest v lowest category 0.86 (95% CI 0.78-0.94), I2=54), risk was more evident in studies that did not adjust for body mass index (BMI) (0.74, 0.64- 0.86, I2=0). Dose-response analysis indicated that risk of breast cancer was reduced by 5% per 0.1g/day (0.95, 0.90 to 1.00, I2=52%) or 0.1% energy/day (0.95, 0.90 to 1.00, I2=79%) increment of dietary marine n-3 PUFA intake. No significant association was observed for fish intake or exposure to alpha linolenic acid.
Higher consumption of dietary marine n-3 PUFA is associated with a lower risk of breast cancer. The associations of fish and alpha linolenic acid intake with risk warrant further investigation of prospective cohort studies. These findings could have public health implications with regard to prevention of breast cancer through dietary and lifestyle interventions.

Selective Estrogen Receptor Modulators and Pharmacogenomic Variation in ZNF423 Regulation of BRCA1 Expression: Individualized Breast Cancer Prevention

The selective estrogen receptor modulators (SERM) tamoxifen and raloxifene can
reduce the occurrence of breast cancer in high-risk women by 50%, but this prevention therapy is not often used.

James N. Ingle, et al. (June 13, 2013. Cancer Discovery ) attempted to identify genetic factors that contribute to variation in SERM breast cancer prevention, using DNA from the NSABP P-1 and P-2 breast cancer prevention trials.


An initial discovery genome-wide association study identified common single nucleotide polymorphisms (SNP) in or near the ZNF423 and CTSO genes that
were associated with breast cancer risk during SERM therapy. The authors then showed that both ZNF423 and CTSO participated in the estrogen-dependent induction of BRCA1 expression, in both cases with SNP-dependent variation in induction. ZNF423 appeared to be an estrogen-inducible BRCA1 transcription
factor. The OR for differences in breast cancer risk during SERM therapy for subjects homozygous for both protective or both risk alleles for ZNF423 and CTSO was 5.71.

SIGNIFICANCE:
This study identified novel, functionally polymorphic genes involved in the estrogen-
dependent regulation of BRCA1 expression, as well as a novel mechanism for genetic variation in SERM therapeutic effect. These observations, and definition of their underlying mechanisms, represent steps toward pharmacogenomically individualized SERM breast cancer prevention.

Among 1 599 551 deliveries with information on early pregnancy BMI, 3082 were extremely preterm, 6893 were very preterm, and 67 059 were moderately preterm.

Risks of extremely, very, and moderately preterm deliveries increased with BMI and the overweight and obesity-related risks were highest for extremely preterm delivery. Among normal-weight women (BMI 18.5-<25), the rate of extremely preterm delivery was 0.17%. As compared with normal-weight women, rates (%) and adjusted odds ratios (ORs [95% CIs]) of extremely preterm delivery were as follows: BMI 25 to less than 30 (0.21%; OR, 1.26; 95% CI, 1.15-1.37), BMI 30 to less than 35 (0.27%; OR, 1.58; 95% CI, 1.39-1.79), BMI 35 to less than 40 (0.35%; OR, 2.01; 95% CI, 1.66-2.45), and BMI of 40 or greater (0.52%; OR, 2.99; 95% CI, 2.28-3.92). Risk of spontaneous extremely preterm delivery increased with BMI among obese women (BMI≥30). Risks of medically indicated preterm deliveries increased with BMI among overweight and obese women.

Conclusions and Relevance In Sweden, maternal overweight and obesity during pregnancy were associated with increased risks of preterm delivery, especially extremely preterm delivery. These associations should be assessed in other populations.

SENTINA is a four-arm, prospective, multicentre cohort study (103 institutions in Germany and Austria, 1737 breast cancer patients scheduled for neoadjuvant chemotherapy). clinically node-negative disease (cN0) Patients underwent sentinel-lymph-node biopsy before neoadjuvant chemotherapy (arm A). If the sentinel node was positive (pN1), a second sentinel-lymph-node biopsy procedure was done after neoadjuvant chemotherapy (arm B). Women with clinically node-positive disease (cN+) received neoadjuvant chemotherapy. Those who converted to clinically node-negative disease after chemotherapy (ycN0; arm C) were treated with sentinel-lymph-node biopsy and axillary dissection. Only patients whose clinical nodal status remained positive (ycN1) underwent axillary dissection without sentinel-lymph-node biopsy (arm D). The primary endpoint was accuracy (false-negative rate) of sentinel-lymph-node biopsy after neoadjuvant chemotherapy for patients who converted from cN1 to ycN0 disease during neoadjuvant chemotherapy (arm C). Secondary endpoints included comparison of the detection rate of sentinel-lymph-node biopsy before and after neoadjuvant chemotherapy, and also the false-negative rate and detection rate of sentinel-lymph-node biopsy after removal of the sentinel lymph node. Analyses were done according to treatment received (per protocol).

Findings
Of 1737 patients who received treatment, 1022 women underwent sentinel-lymph-node biopsy before neoadjuvant chemotherapy (arms A and B), with a detection rate of 99·1% (95% CI 98·3—99·6; 1013 of 1022). In patients who converted after neoadjuvant chemotherapy from cN+ to ycN0 (arm C), the detection rate was 80·1% (95% CI 76·6—83·2; 474 of 592) and false-negative rate was 14·2% (95% CI 9·9—19·4; 32 of 226). The false-negative rate was 24·3% (17 of 70) for women who had one node removed and 18·5% (10 of 54) for those who had two sentinel nodes removed (arm C). In patients who had a second sentinel-lymph-node biopsy procedure after neoadjuvant chemotherapy (arm B), the detection rate was 60·8% (95% CI 55·6—65·9; 219 of 360) and the false-negative rate was 51·6% (95% CI 38·7—64·2; 33 of 64).

Interpretation
Sentinel-lymph-node biopsy is a reliable diagnostic method before neoadjuvant chemotherapy. After systemic treatment or early sentinel-lymph-node biopsy, the procedure has a lower detection rate and a higher false-negative rate compared with sentinel-lymph-node biopsy done before neoadjuvant chemotherapy. These limitations should be considered if biopsy is planned after neoadjuvant chemotherapy.

Prediction of Regression and Relapse of Endometrial Hyperplasia With Conservative Therapy

Gallos et al (Obstetrics & Gynecology. 121(6):1165-1171, June 2013. doi: 10.1097/AOG.0b013e31828cb563) identified predictors for regression and relapse of endometrial hyperplasia treated with levonorgestrel-releasing intrauterine system or oral progestogens using a cohort study of women treated with levonorgestrel-releasing intrauterine system or oral progestogens for complex hyperplasia or atypical complex hyperplasia.

Regression was evaluated in 344 women over a 12-year period, with a median follow-up of 58.8 months for levonorgestrel-releasing intrauterine system compared with 95.1 months for oral progestogens. In women treated with levonorgestrel-releasing intrauterine system for complex hyperplasia, 221 women regressed (96.5%, 221/229) and BMI 35 or higher was associated with 5 fold higher failure to regress. Relapse was evaluated in 219 women over a 9-year period, with median follow-up of 67 months for levonorgestrel-releasing intrauterine system and 96.8 months for oral progestogens. In women treated with levonorgestrel-releasing intrauterine system for complex hyperplasia, 18 women experienced relapse (12.7%, 18/142) and BMI 35 or higher was found to be a strong independent predictor of relapsed endometrial hyperplasia (HR 18.93, 95% CI 3.93–91.15; P<.001). Only 3.3% of women with complex hyperplasia treated with levonorgestrel-releasing intrauterine system and with BMI less than 35 experienced relapse during long-term follow-up compared with 32.6% of women with BMI 35 or higher.

CONCLUSION: Body mass index 35 or higher is strongly associated with failure to regress and relapse of complex hyperplasia treated with levonorgestrel-releasing intrauterine system.

Challenges to the Measurement of Estradiol: An Endocrine Society Position Statement concluded that The measurement of estradiol in biological fluids is important in human biology from cradle to grave. In addition to its centrality in sexual development, it has significant effects on skin, blood vessels, bone, muscle, coagulation, hepatic cells, adipose tissue, the kidney, the gastrointestinal tract, brain, lung, and pancreas. Alterations in its plasma concentration have been implicated in coronary artery disease, stroke, and breast cancer. Although modern immunoassays and liquid chromatography/tandem mass spectrometry-based methods for estradiol are reasonably well suited to the diagnosis and management of infertility (nonetheless, imprecision and method-to-method differences remain problematic), the very low concentrations that appear to be crucial in nonreproductive tissues are a separate and more difficult issue. Such levels of estradiol are too low to be routinely measured accurately or precisely, and further evolution of analytical methods and the way in which estradiol is standardized is needed.

They conducted a Cluster-randomized controlled trial in 31 Belarusian maternity hospitals and their affiliated clinics, randomized into 1 of 2 groups: breastfeeding promotion intervention (n = 16) or usual practices (n = 15). Participants were 17 046 breastfeeding mother-infant pairs enrolled in 1996 and 1997, of whom 13 879 (81.4%) were followed up between January 2008 and December 2010 at a median age of 11.5 years. The intervention was the Breastfeeding promotion intervention modeled on the WHO/UNICEF Baby-Friendly Hospital Initiative (World Health Organization/United Nations Children's Fund).
The experimental intervention substantially increased breastfeeding duration and exclusivity when compared with the control (43% vs 6% exclusively breastfed at 3 months and 7.9% vs 0.6% at 6 months) but did not prevent overweight or obesity, nor did it affect IGF-I levels at age 11.5 years.
Breastfeeding may have many advantages but population strategies to increase the duration and exclusivity of breastfeeding are unlikely to curb the obesity epidemic.

Circulating Tumor DNA to Monitor Metastatic Breast Cancer
Sarah-Jane Dawson et al (N Engl J Med 2013. DOI: 10.1056/NEJMoa1213261) analysed the use of Circulating Tumor DNA to Monitor Metastatic Breast Cancer. They compared the radiographic imaging of tumors with the assay of circulating tumor DNA, CA 15-3, and circulating tumor cells in 30 women with metastatic breast cancer who were receiving systemic therapy. They used targeted or whole-genome sequencing to identify somatic genomic alterations and designed personalized assays to quantify circulating tumor DNA in serially collected plasma specimens. CA 15-3 levels and numbers of circulating tumor cells were measured at identical time points. Circulating tumor DNA was successfully detected in 29 of the 30 women (97%) in whom somatic genomic alterations were identified; CA 15-3 and circulating tumor cells were detected in 21 of 27 women (78%) and 26 of 30 women (87%), respectively. Circulating tumor DNA levels showed a greater dynamic range, and greater correlation with changes in tumor burden, than did CA 15-3 or circulating tumor cells. Among the measures tested, circulating tumor DNA provided the earliest measure of treatment response in 10 of 19 women (53%).

Risk of Ischemic Heart Disease in Women after Radiotherapy for Breast Cancer
Sarah C. Darby, et al N Engl J Med 2013; 368:987-998March 14, 2013 conducted a population-based case–control study of major coronary events (i.e., myocardial infarction, coronary revascularization, or death from ischemic heart disease) in 2168 women who underwent radiotherapy for breast cancer between 1958 and 2001 in Sweden and Denmark; the study included 963 women with major coronary events and 1205 controls. For each woman, the mean radiation doses to the whole heart and to the left anterior descending coronary artery were estimated from her radiotherapy chart. The overall average of the mean doses to the whole heart was 4.9 Gy (range, 0.03 to 27.72). Rates of major coronary events increased linearly with the mean dose to the heart by 7.4% per gray (95%CI, 2.9- 14.5; P<0.001), with no apparent threshold. The increase started within the first 5 years after radiotherapy and continued into the third decade after radiotherapy. The proportional increase in the rate of major coronary events per gray was similar in women with and women without cardiac risk factors at the time of radiotherapy.

Cox et al (BMJ 2013;346:f441 ) studied in Flanders the cohort of live born singleton births delivered at 24–44 weeks of gestation (n=606 877, with n=448 520 spontaneous deliveries). They found reductions in the risk of preterm birth after the introduction of each phase of the smoking ban. A step change in the risk of spontaneous preterm delivery of −3.13% (95% CI −4.37% to −1.87%; P<0.01) occurred on 1 January 2007 (ban on smoking in restaurants), and an annual slope change of −2.65% (−5.11% to −0.13%; P=0.04) after 1 January 2010 (ban on smoking in bars serving food). The analysis for all births gave similar results: a step change of −3.18% (−5.38% to −0.94%; P<0.01) on 1 January 2007, and an annual slope change of −3.50% (−6.35% to −0.57%; P=0.02) after 1 January 2010. These changes could not be explained by personal factors (infant sex, maternal age, parity, socioeconomic status, national origin, level of urbanisation); time related factors (underlying trends, month of the year, day of the week); or population related factors (public holidays, influenza epidemics, and short term changes in apparent temperature and particulate air pollution).
This study shows a consistent pattern of reduction in the risk of preterm delivery with successive population interventions to restrict smoking.

Work stress and risk of cancer: meta-analysis of 5700 incident cancer events in 116 000 European men and women (BMJ 2013;346:f165)
Katriina Heikkilä et al investigated whether work related stress, measured and defined as job strain, is associated with the overall risk of cancer and the risk of colorectal, lung, breast, or prostate cancers.
They conducted a Meta-analysis of pooled prospective individual participant data from 12 European cohort studies including 116 056 men and women aged 17-70 who were free from cancer at study baseline and were followed-up for a median of 12 years. Work stress was measured and defined as job strain, which was self reported at baseline. Incident cancers (all n=5765, colorectal cancer n=522, lung cancer n=374, breast cancer n=1010, prostate cancer n=865) were ascertained from cancer, hospital admission, and death registers. Data were analysed in each study with Cox regression and the study specific estimates pooled in meta-analyses. Models were adjusted for age, sex, socioeconomic position, body mass index (BMI), smoking, and alcohol intake There was no clear evidence for an association between the categories of job strain and the risk of cancer.

Exposure to bisphosphonates and risk of gastrointestinal cancers: series of nested case-control studies with QResearch and CPRD data
Vinogradova et al (BMJ 2013; 346 doi: http://dx.doi.org/10.1136/bmj.f114 (Published 16 January 2013) Cite this as: BMJ 2013;346:f114 ) investigated the association between use of bisphosphonates estimated from prescription information and risk of gastrointestinal cancers using a series of nested case-control studies based on general practices in the United Kingdom contributing to the QResearch primary care database (660) and the Clinical Practice Research Datalink (CPRD) (643).
Patients aged ≥50 with a diagnosis of a primary gastrointestinal cancer in 1997-2011 were each matched with up to five controls by age, sex, practice, and calendar year.
Odds ratios for incident gastrointestinal cancers (colorectal, oesophageal, gastric) and use of bisphosphonates were calculated, adjusted for smoking status, ethnicity, comorbidities, and use of other drugs.
20 106 and 19 035 cases of colorectal cancer cases, 5364 and 5135 cases of oesophageal cancer cases, and 3155 and 3157 cases of gastric cancer were identified from QResearch and CPRD, respectively. Overall bisphosphonate use (at least one prescription) was not associated with risk of colorectal, oesophageal, or gastric cancers in either database. Adjusted OR (95%CI) for QResearch and CPRD were 0.97 (0.79- 1.18) and 1.18 (0.97 - 1.43) for oesophageal cancer; 1.12 (0.87 - 1.44) and 0.79 (0.62 -1.01) for gastric cancer; and 1.03 (0.94 - 1.14) and 1.10 (1.00 - 1.22) for colorectal cancer. Additional analyses showed no difference between types of bisphosphonate for risk of oesophageal and colorectal cancers. For gastric cancer, alendronate use was associated with an increased risk (1.47, 1.11- 1.95; P=0.008), but only in data from the QResearch database and without any association with duration and with no definitive confirmation from sensitivity analysis.
Conclusions In this series of population based case-control studies in two large primary care databases, exposure to bisphosphonates was not associated with an increased risk of common gastrointestinal cancers.

Incidence of pulmonary and venous thromboembolism in pregnancies after in vitro fertilisation: cross sectional study
Henriksson et al ( BMJ 2013; 346 doi: http://dx.doi.org/10.1136/bmj.e8632 (Published 15 January 2013) Cite this as: BMJ 2013;346:e8632) estimated the risk of pulmonary embolism and venous thromboembolism in pregnant women after in vitro fertilization using a cross sectional study in Sweden. 23 498 women who had given birth after in vitro fertilisation between 1990 and 2008 were matched to 116 960 individually women with natural pregnancies. Venous thromboembolism occurred in 4.2/1000 women (n=99) after in vitro fertilisation compared with 2.5/1000 (n=291) in women with natural pregnancies (HR 1.77, 95% CI 1.41 - 2.23). The risk of venous thromboembolism was increased during the whole pregnancy (P<0.001) and differed between the trimesters (P=0.002). The risk was particularly increased during the first trimester, at 1.5/1000 after in vitro fertilisation versus 0.3/1000 (HR 4.22, 2.46- 7.26). The proportion of women experiencing pulmonary embolism during the first trimester was 3.0/10 000 after in vitro fertilisation versus 0.4/10 000 (HR 6.97, 2.21- 21.96).

Levonorgestrel Intrauterine System versus Medical Therapy for Menorrhagia
Janesh Gupta et al (N Engl J Med 2013; 368:128-137January 10, 2013DOI: 10.1056/NEJMoa1204724) randomly assigned 571 women with menorrhagia to treatment with levonorgestrel-IUS or usual medical treatment (tranexamic acid, mefenamic acid, combined estrogenâprogestogen, or progesterone alone). The primary outcome was the patient-reported score on the Menorrhagia Multi-Attribute Scale (MMAS) (ranging from 0 to 100, with lower scores indicating greater severity), assessed over a 2-year period. Secondary outcomes included general quality-of-life and sexual-activity scores and surgical intervention.
MMAS scores improved from baseline to 6 months in both the levonorgestrel-IUS group and the usual-treatment group (mean increase, 32.7 and 21.4 points, respectively; P<0.001 for both comparisons). The improvements were maintained over a 2-year period but were significantly greater in the levonorgestrel-IUS group than in the usual-treatment group (mean between-group difference, 13.4 points; 95% confidence interval, 9.9 to 16.9; P<0.001). Improvements in all MMAS domains (practical difficulties, social life, family life, work and daily routine, psychological well-being, and physical health) were significantly greater in the levonorgestrel-IUS group than in the usual-treatment group, and this was also true for seven of the eight quality-of-life domains. At 2 years, more of the women were still using the levonorgestrel-IUS than were undergoing the usual medical treatment (64% vs. 38%, P<0.001). There were no significant between-group differences in the rates of surgical intervention or sexual-activity scores. There were no significant differences in serious adverse events between groups.
The authors concluded that in women with menorrhagia who presented to primary care providers, the levonorgestrel-IUS was more effective than usual medical treatment in reducing the effect of heavy menstrual bleeding on quality of life.

Gonadatrophin Suppression to Prevent Chemotherapy-Induced Ovarian Damage: A Randomized Controlled Trial
Elgindy, et al (Obstetrics & Gynecology: January 2013 - Volume 121 - Issue 1 - p 78–86
doi: http://10.1097/AOG.0b013e31827374e2) estimated the effectiveness of gonadotropin-releasing hormone (GnRH) analogues cotreatment in preventing chemotherapy-induced amenorrhea in young breast cancer patients undergoing cyclophosphamide-based chemotherapy in 100 hormone-insensitive breast cancer participants (aged 18-40 years) in Egypt. Fifty women ready for early chemotherapy were randomized to receive either chemotherapy alone (arm I) or chemotherapy after downregulation (estradiol less than 50 pg/mL) by GnRH antagonist and agonist (arm II). Then, GnRH antagonist was discontinued and agonist was continued until the end of chemotherapy. When chemotherapy was to start later than 10 days after study inclusion, 50 women were randomized to receive either chemotherapy alone (arm III) or chemotherapy after downregulation with GnRH agonist (arm IV). Resumption of menstruation at 12 months after end of chemotherapy was the primary outcome. Postchemotherapy hormonal and ultrasound changes were secondary outcomes.
Twelve months after termination of chemotherapy, there were no differences in menstruation resumption rates between GnRH-treated patients and control group individuals in either early (80% in arms I and II, risk ratio 1, 95% confidence interval 0.7-.32; P=1.00) or delayed chemotherapy groups (80% and 84% in arms III and IV, risk ratio 0.95, 95% confidence interval 0.73-1.235; P=.71).
There were no differences in hormonal and ultrasound markers between GnRH analogue users and control group individuals. The use of GnRH analogue cotreatment did not predict independently the odds of menstruating at 12 months.

Risk-Reducing Salpingo-oophorectomy (RRSO) and Ovarian Cancer Screening in 1077 Women After BRCA Testing
Gabriel N. Mannis, et al (Arch Intern Med. 2012;():1-8. doi:10.1001/2013.jamainternmed.962. ) surveyed a large cohort of women after BRCA testing to identify the prevalence and posttest predictors of risk-reducing and screening interventions, a median of 3.7 years after BRCA testing, in 1447 women who received genetic counseling and BRCA testing. Among the respondents (77.6% response rate), 201 women (18.7%) received positive test results for a deleterious mutation, 103 women (9.6%) received true-negative results, and 773 women (71.8%) received uninformative results. Overall, 19.1% of eligible women underwent RRSO and 39.6% used screening procedures. A positive BRCA result predicted RRSO (odds ratio [OR], 28.1; 95% CI, 16.2-48.6), TVUS (9.5 [4.3-21.0]), and serum CA-125 (13.0 [5.5-29.0]). Similarly, a true-negative BRCA result reduced the OR for RRSO (0.1 [0.0-0.6]), TVUS (0.2 [0.1-0.5]), and serum CA-125 (0.3 [0.1-0.7]). Of the 71.8% of women who received uninformative results after BRCA testing, 12.3% subsequently underwent RRSO, 33.8% reported ever having undergone screening serum CA-125 since BRCA testing, and 37.3% reported ever having undergone screening TVUS since BRCA testing.
Conclusions Results of BRCA testing strongly predict RRSO and ovarian cancer screening. Use of RRSO and ovarian screening was reported in a sizable percentage of non- BRCA carriers despite insufficient data to determine the effectiveness of these interventions.

Long-term effects of continuing adjuvant tamoxifen to 10 years versus stopping at 5 years after diagnosis of oestrogen receptor-positive breast cancer: ATLAS, a randomised trial
Davis et al (lancet h ttp://ww w.th elanc et.co m/po pup ? fileName=cite- using- doi) report that Interpretation
For women with ER-positive disease, continuing tamoxifen to 10 years rather than stopping at 5 years produces a further reduction in recurrence and mortality, particularly after year 10. These results, taken together with results from previous trials of 5 years of tamoxifen treatment versus none, suggest that 10 years of tamoxifen treatment can approximately halve breast cancer mortality during the second decade after diagnosis.

Extracts from Intimate-Partner Violence (IPV) — What Physicians Can Do Jane M. Liebschutz, M.D., M.P.H., and Emily F. Rothman, Sc.D.
NEJM 2012

All health care providers should be alert to aspects of patients’ histories or symptoms that could suggest IPV and then should follow up with specific questions.
. …all primary care physicians should now be screening female patients 12 years of age or older for IPV. Specialty professional organizations recommend that obstetricians and pediatricians also consider performing regular IPV screening.
Numerous IPV screening instruments may be used to begin a dialogue with the patient; one of them (known as HITS) is shown in the table. Another question that may be used to start a discussion about safety at home is
simply, “Are you afraid of your partner or anyone else?”
There are several steps doctors should take when patients report potential IPV.
First, clinicians should acknowledge the patient’s admission of abuse: we advise thanking the patient for trusting the provider with the information and expressing concern about the patient’s safety.
Second, we suggest asking the patient if he or she would like to be connected to IPV advocacy services.
If patients do want legal assistance, counseling, shelter, or other services, local domestic violence agencies affiliated with the state coalition are likely to be the most reliable resources (see box).
Third, clinicians should offer the patient the National Domestic Violence hotline number (see box);
Fourth, clinicians should consider whether child protective services are required.
Fifth, they should screen the patient for coexisting depression, anxiety, and substance abuse.
Use caution when prescribing sedatives, since the sedating action may diminish patients’ physical or mental ability to defend themselves.
Even if a patient screen negative, we would encourage the provider to state that many patients do experience IPV at some point and that there are many resources to help people who feel unsafe in their relationships.

Effect of Three Decades of Screening Mammography on Breast-Cancer Incidence
Archie Bleyer, et al (N Engl J Med 2012; 367:1998-2005November 22, 2012DOI: 10.1056/NEJMoa1206809) used Surveillance, Epidemiology, and End Results data to examine trends from 1976 through 2008 in the incidence of early-stage breast cancer (ductal carcinoma in situ and localized disease) and late-stage breast cancer (regional and distant disease) among women 40 years of age or older.
The introduction of screening mammography in the United States has been associated with a doubling in the number of cases of early-stage breast cancer that are detected each year, from 112 to 234 cases per 100,000 women — an absolute increase of 122 cases per 100,000 women. Concomitantly, the rate at which women present with late-stage cancer has decreased by 8%, from 102 to 94 cases per 100,000 women — an absolute decrease of 8 cases per 100,000 women. With the assumption of a constant underlying disease burden, only 8 of the 122 additional early-stage cancers diagnosed were expected to progress to advanced disease. After excluding the transient excess incidence associated with hormone-replacement therapy and adjusting for trends in the incidence of breast cancer among women younger than 40 years of age, they estimated that breast cancer was overdiagnosed (i.e., tumors were detected on screening that would never have led to clinical symptoms) in 1.3 million U.S. women in the past 30 years. The authors estimated that in 2008, breast cancer was overdiagnosed in more than 70,000 women; this accounted for 31% of all breast cancers diagnosed.
Conclusions:
Despite substantial increases in the number of cases of early-stage breast cancer detected, screening mammography has only marginally reduced the rate at which women present with advanced cancer. Although it is not certain which women have been affected, the imbalance suggests that there is substantial overdiagnosis, accounting for nearly a third of all newly diagnosed breast cancers, and that screening is having, at best, only a small effect on the rate of death from breast cancer.

Among patients 40 years of age or older, 18,721 had used statins regularly before the cancer diagnosis and 277,204 had never used statins. Multivariable-adjusted HR for statin users, as compared with patients who had never used statins, were 0.85 (95% CI, 0.83 to 0.87) for death from any cause and 0.85 (95% CI, 0.82 to 0.87) for death from cancer. The reduced cancer-related mortality among statin users as compared with those who had never used statins was observed for each of 13 cancer types.

The rate of any new morphometric vertebral fracture was 1.6% in the zoledronic acid group and 4.9% in the placebo group over the 24-month period, representing a 67% risk reduction with zoledronic acid (RR, 0.33; 95% CI, 0.16- 0.70; P=0.002). As compared with men who received placebo, men who received zoledronic acid had fewer moderate-to-severe vertebral fractures (P=0.03) and less height loss (P=0.002). Fewer participants who received zoledronic acid had clinical vertebral or nonvertebral fractures, although this difference did not reach significance because of the small number of fractures. Bone mineral density was higher and bone-turnover markers were lower in the men who received zoledronic acid (P<0.05 for both comparisons). Results were similar in men with low serum levels of total testosterone. The zoledronic acid and placebo groups did not differ significantly with respect to the incidence of death (2.6% and 2.9%, respectively) or serious adverse events (25.3% and 25.2%).

Rita S. Mehta, et al (N Engl J Med 2012; 367:435-444August 2, 2012) tested whether the Combination of Anastrozole and Fulvestrant would be more effective than anastrozole alone in patients with hormone-receptor (HR)–positive metastatic breast cancer
Postmenopausal women with previously untreated metastatic disease were randomly assigned, in a 1:1 ratio, to receive either 1 mg of anastrozole orally every day (group 1), with crossover to fulvestrant alone strongly encouraged if the disease progressed, or anastrozole and fulvestrant in combination (group 2). Patients were stratified according to prior or no prior receipt of adjuvant tamoxifen therapy. Fulvestrant was administered intramuscularly at a dose of 500 mg on day 1 and 250 mg on days 14 and 28 and monthly thereafter. The primary end point was progression-free survival, with overall survival designated as a prespecified secondary outcome. The median progression-free survival was 13.5 months in group 1 and 15.0 months in group 2 (HR for progression or death with combination therapy, 0.80; 95% [CI], 0.68 to 0.94; P=0.007 by the log-rank test). The combination therapy was generally more effective than anastrozole alone in all subgroups, with no significant interactions. Overall survival was also longer with combination therapy (median, 41.3 months in group 1 and 47.7 months in group 2; HR for death, 0.81; 95% CI, 0.65 to 1.00; P=0.05 by the log-rank test), despite the fact that 41% of the patients in group 1 crossed over to fulvestrant after progression. Three deaths that were possibly associated with treatment occurred in group 2. The rates of grade 3 to 5 toxic effects did not differ significantly between the two groups.
Conclusions
The combination of anastrozole and fulvestrant was superior to anastrozole alone or sequential anastrozole and fulvestrant for the treatment of HR-positive metastatic breast cancer, despite the use of a dose of fulvestrant that was below the current standard.

N° 729 TOPIC: MENOPAUSE
A decade after the Women's Health Initiative—the experts do agree
Stuenkel et al Fertil & Steril 9.07.12 in press
Overview: ,Systemic hormone therapy is an acceptable option for relatively young (up to age 59 or within 10 years of menopause) and healthy women who are bothered by moderate to severe menopausal symptoms. Individualization is key in the decision to use hormone therapy. Consideration should be given to the woman's quality-of-life priorities as well as her personal risk factors such as age, time since menopause, and her risk of blood clots, heart disease, stroke, and breast cancer.
Symptom Relief Benefits
Systemic hormone therapy is the most effective treatment for most menopausal symptoms, including vasomotor symptoms and vaginal atrophy. Estrogen therapy as a single agent is sufficient in women who have undergone hysterectomy.
Progestogen therapy is required to prevent endometrial cancer when estrogen is used systemically in women with a uterus.
Local estrogen therapy is effective and preferred for women whose symptoms are limited to vaginal dryness or discomfort with intercourse; low-dose vaginal estrogen therapy is recommended in this setting.
Hormone therapy risks
Vascular Risks
Both estrogen therapy and estrogen with progestogen therapy increase the risk of venous thromboembolic events—deep vein thrombosis and pulmonary emboli. Although the risks of venous thromboembolic events and ischemic stroke increase with either estrogen therapy or estrogen and progestogen therapy, the risk is rare in the 50- to 59-year-old age group.
Breast Cancer
An increased risk of breast cancer is seen with 5 years or more of continuous estrogen with progestogen therapy, possibly earlier with continuous use since menopause. The risk is real but not great, and the risk decreases after hormone therapy is discontinued. Use of estrogen alone for a mean of 7 years in the Women's Health Initiative did not increase the risk of breast cancer.
Duration of therapy
The lowest dose of hormone therapy should be used for the shortest amount of time to manage menopausal symptoms. Although fewer than 5 years is recommended for estrogen with progestogen therapy, duration should be individualized.
For estrogen therapy alone, more flexibility in duration of therapy may be possible. There are reports of increased risk of breast cancer after 10 to 15 years of use in large observational studies with estrogen alone.
Additional information
In observational studies, both transdermal estrogen therapy and low-dose oral estrogen therapy have been associated with lower risks of venous thromboembolic events and stroke than standard doses of oral estrogen, but comparison randomized clinical trials are not yet available.
Many options for Food and Drug Administration–approved bioidentical hormone therapy (estradiol and progesterone) are available. Evidence is lacking that custom compounded bioidentical hormone therapy is safe or effective. Many medical organizations and societies agree in recommending against the use of custom compounded hormone therapy for menopause management, particularly given concerns regarding content, purity, and labeling. There is a lack of safety data supporting the use of estrogen or estrogen with progestogen therapy in breast cancer survivors. Nonhormonal therapies should be the first approach in managing menopausal symptoms in breast cancer survivors.
Conclusion
Leading medical societies devoted to the care of menopausal women agree that the decision to initiate hormone therapy should be for the indication of treatment of menopause-related symptoms. Although research is ongoing and these recommendations may be modified over time, there is no question that hormone therapy has an important role in managing symptoms for women during the menopausal transition and in early menopause.

I to K, Blinde r VS, Elkin EB (J Clin Oncol. 2012 May 1;30(13):1468-75. Epub 2012 Feb 27.)
Evaluated the "Cost effectiveness of fracture prevention in postmenopausal women who receive aromatase inhibitors for early breast cancer, using a Markov state transition model to simulate clinical practice and outcomes in a hypothetical cohort of women age 60 years with HR-positive EBC starting a 5-year course of AI therapy after primary surgery for breast cancer. Outcomes were quality-adjusted life-years (QALYs), lifetime cost, and incremental cost-effectiveness ratio (ICER). They compared the following strategies: no intervention; one-time bone mineral density (BMD) screening and selective bisphosphonate therapy in women with osteoporosis or osteopenia; annual BMD screening and selective bisphosphonate therapy in women with osteoporosis or osteopenia; and universal bisphosphonate therapy.
RESULTS:
ICERs for annual BMD screening followed by oral bisphosphonates for those with osteoporosis, annual BMD screening followed by oral bisphosphonates for those with osteopenia, and universal treatment with oral bisphosphonates were $87,300, $129,300, and $283,600 per QALY gained, respectively. One-time BMD screening followed by oral bisphosphonates for those with osteoporosis or osteopenia was dominated. These results were sensitive to age at the initiation of AI therapy, type of bisphosphonates, post-treatment residual effect of bisphosphonates, and a potential adjuvant benefit of intravenous bisphosphonates.
CONCLUSION:
In postmenopausal women receiving adjuvant AIs for HR-positive EBC, a policy of baseline and annual BMD screening followed by selective treatment with oral bisphosphonates for those diagnosed with osteoporosis is a cost-effective use of societal resources.

A meta-analyses of five comparative studies showed an increased risk of EC in women with an odds ratio of 2.89 with a 95% confidence interval of 1.52–5.48. This translates into a 9% lifetime risk of EC in Caucasian women with PCOS compared with 3% in women without it.

The genomic and transcriptomic architecture of 2,000 breast tumours reveals novel subgroups
C hri stina Curtis et al (Nature (2012) doi:10.1038/nature10983) presented an integrated analysis of copy number and gene expression in a discovery and validation set of 997 and 995 primary breast tumours, respectively, with long-term clinical follow-up.
They identified putative cancer genes, including deletions in PPP2R2A, MTAP and MAP2K4. Unsupervised analysis of paired DNA–RNA profiles revealed novel subgroups with distinct clinical outcomes, which reproduced in the validation cohort. These include a high-risk, oestrogen-receptor-positive 11q13/14 cis-acting subgroup and a favourable prognosis subgroup devoid of CNAs. Trans-acting aberration hotspots were found to modulate subgroup-specific gene networks, including a TCR deletion-mediated adaptive immune response in the ‘CNA-devoid’ subgroup and a basal-specific chromosome 5 deletion-associated mitotic network.
These results provide a novel molecular stratification of the breast cancer population, derived from the impact of somatic CNAs on the transcriptome.
A more simple explanation is provided in the BMJ 2012;344:e2829
“Before this study breast cancer was basically classified into four types according to whether the tumour was positive for receptors for oestrogen (Er+), human epidermal growth factor receptor 2 (Her2+), and progesterone (Pr+). Er+ tumours may respond to tamoxifen or aromatase inhibitors, whereas Her2+ tumours may respond to trastuzumab (Herceptin). Tumours that are negative for all these receptors are known as triple negative: they are very aggressive, the only treatment is chemotherapy, and there is no targeted therapy.
Seventy per cent of women have breast cancer that is Er+ and Her2−, and the researchers have now subdivided this group into seven subtypes. The likelihood that a woman with a high proliferation Er+ and Her2− tumour would be alive after 10 years is 75%, but when these tumours are subdivided into the seven new types the researchers found that survival varied from less than 40% to more than 80% after 15 years.
Of the other three new subtypes, one “robustly identifies” the Her2+ tumours, Caldas said. “All previous molecular tests have failed to do that properly.” The second contains most of the triple negative tumours, which have a very poor prognosis.
The third and final subtype contains a subset of Er+ tumours, a subset of Er− tumours, and a subset of triple negative tumours. What this group have in common is significant infiltration of inflammatory cells and lymphocytes. “This subset of breast cancer is a very important one for us to have recognised,” said Caldas, “because it looks like in this subset the immune system is playing a very active role in improving the prognosis of these women.”
Subsequent studies will try to understand why in this group the immune system seems to be particularly engaged and fighting against the tumour, giving the woman a better prognosis, Caldas predicted. “The fact that we know that breast cancer is not one disease but 10 different types of disease will allow us to go forward and look within these groups and see if we can detect differential responses.””

Tat yan a Shamliyan, et al (Annals of Internal Medicine April 3, 2012, 156 (7)) report a systematic Review on Benefits and Harms of Pharmacologic Treatment for Urinary Incontinence in Women. 94 RCTs were eligible. Pooled analyses showed that among drugs for urgency UI, per 1000 treated, continence was achieved in 130 with fesoterodine (CI, 58- 202), 85 with tolterodine (CI, 40-129), 114 with oxybutynin (CI, 64-163), 107 with solifenacin (CI, 58- 156), and 114 with trospium (CI, 83- 144). Rates of treatment discontinuation due to adverse effects were 31 per 1000 treated with fesoterodine (CI, 10- 56), 63 with oxybutynin (CI, 12- 127), 18 with trospium (CI, 4- 33), and 13 with solifenacin (CI, 1- 26). The studies' inconsistent definitions of improvement in UI and quality of life hampered synthesis of evidence.
Conclusion: Overall, drugs for urgency UI showed similar small benefit. Therapeutic choices should consider the harms profile. Evidence for long-term adherence and safety of treatments is lacking.

Anderson et al (WHI study) reported in the Lancet Oncol. 2012 Mar 6. [Epub ahead of print]) that after a median follow-up of 11·8 years (IQR 9·1-12·9), the use of oestrogen for a median of 5·9 years (2·5-7·3) was associated with lower incidence of invasive breast cancer (151 cases, 0·27% per year) compared with placebo (199 cases, 0·35% per year; HR 0·77, 95% CI 0·62-0·95; p=0·02) with no difference (p=0·76) between intervention phase (0·79, 0·61-1·02) and post-intervention phase effects (0·75, 0·51-1·09). In subgroup analyses, they noted that the breast cancer risk reduction with oestrogen use was concentrated in women without benign breast disease (p=0·01) or a family history of breast cancer (p=0·02). In the oestrogen group, fewer women died from breast cancer (six deaths, 0·009% per year) compared with controls (16 deaths, 0·024% per year; HR 0·37, 95% CI 0·13-0·91; p=0·03). Fewer women in the oestrogen group died from any cause after a breast cancer diagnosis (30 deaths, 0·046% per year) than did controls (50 deaths, 0·076%; HR 0·62, 95% CI 0·39-0·97; p=0·04).
The authors noted that these findings provide reassurance for women with hysterectomy seeking relief of climacteric symptoms in terms of the effects of oestrogen use for about 5 years on breast cancer incidence and mortality. However, their data do not support use of oestrogen for breast cancer risk reduction because any noted benefit probably does not apply to populations at increased risk of such cancer.

N° 722 TOPIC: MENOPAUSE
Mishra GD Kuh D (BMJ. 2012 Feb 8;344:e402. doi: 10.1136/bmj.e402) reported Health symptoms during midlife in relation to menopausal transition in a British prospective cohort study of 695 women followed-up since birth in 1946 and annually from age 47 to 54 who experienced natural menopause and reported on 20 common health symptoms. A small proportion of women (10%, n=63) had a severe psychological symptom profile that peaked at or in the year after menopause. For vasomotor symptoms, 14% of women (n=83) had the early severe profile that also peaked around early postmenopause and then declined noticeably; 11% (n=67) had the late severe profile of bothersome symptoms that increased rapidly in perimenopause and remained high for four years or more after menopause. Women were less likely to have a profile for severe vasomotor symptoms if they were from a non-manual social class (odds ratio 0.79, 95%CI 0.57 to 1.01) or had degree level qualifications (0.37, 0.18 to 0.77). The 14% of women (n=85) who had the late severe profile for sexual discomfort showed a similar increase in symptoms until menopause, with symptoms persisting after menopause. Married women were more likely to have the late severe or late moderate profile than women of other marital status (2.40, 1.30 to 4.41). Four profiles each were identified for somatic symptoms (mild, moderate, severe, and very severe), although these did not vary by chronological age or age at menopause.

N° 721 TOPIC: TVT, WOMEN’S HEALTH
The efficacy of tension-free vaginal tape (TVT) to transobturator tape in the treatment of women with stress urinary incontinence (SUI) and intrinsic sphincter deficiency at 3-year follow-up was studied in 164 women who were randomized to either treatment after diagnosis of urodynamic stress incontinence and intrinsic sphincter deficiency. Concomitant pelvic organ prolapse surgery was not an exclusion criterion. The primary outcome assessed at 3-year follow-up was symptomatic stress incontinence requiring repeat surgery. Secondary outcomes were quality-of-life parameters assessed by validated questionnaires and numerical success score.
At 3 years, 15 of the 75 (20%) women in the transobturator tape group underwent repeat surgery to correct SUI compared with one of the 72 (1.4%) in the TVT group. In other words, if TVT had been used exclusively, repeat surgery would have been avoided in one in six patients. The risk ratio of repeat surgery was 15 (95% CI: 2–113; P<.001) times greater in the transobturator tape group. In the transobturator tape group, the median time to repeat surgery was 15.6 months compared with 43.7 months for TVT (P<.001). The quality-of-life outcomes did show an improvement in both groups before and after surgery but no difference between the two slings in the Urogenital Distress Inventory short form, the Incontinence Impact Questionnaire short form, and a patient-rated numerical success score.
CONCLUSION: The long-term cure rates for retropubic TVT are significantly greater than for transobturator tape in women with urodynamic stress incontinence and intrinsic sphincter deficiency. Urethral functions tests such as urethral closure pressure and Valsalva leak point pressures are of value in determining what surgery to perform.

Bone-Density Testing Interval and Transition to Osteoporosis in Older Women
Gourlay et al (N Engl J Med 2012; 366:225-233January 19, 2012) studied 4957 women, 67 years of age or older, with normal BMD (T score at the femoral neck and total hip, −1.00 or higher) or osteopenia (T score, −1.01 to −2.49) and with no history of hip or clinical vertebral fracture or of treatment for osteoporosis, and followed prospectively for up to 15 years. The BMD testing interval was defined as the estimated time for 10% of women to make the transition to osteoporosis before having a hip or clinical vertebral fracture, with adjustment for estrogen use and clinical risk factors. Transitions from normal BMD and from three subgroups of osteopenia (mild, moderate, and advanced) were analyzed with the use of parametric cumulative incidence models. Incident hip and clinical vertebral fractures and initiation of treatment with bisphosphonates, calcitonin, or raloxifene were treated as competing risks.
The estimated BMD testing interval was 16.8 years (95% CI, 11.5- 24.6) for women with normal BMD, 17.3 years (95% CI, 13.9 to 21.5) for women with mild osteopenia, 4.7 years (95% CI, 4.2 to 5.2) for women with moderate osteopenia, and 1.1 years (95% CI, 1.0 to 1.3) for women with advanced osteopenia.
The authors concluded that osteoporosis would develop in less than 10% of older, postmenopausal women during rescreening intervals of approximately 15 years for women with normal bone density or mild osteopenia, 5 years for women with moderate osteopenia, and 1 year for women with advanced osteopenia.

Association between bisphosphonate use and implant survival after primary total arthroplasty of the knee or hip: population based retrospective cohort study
Daniel Prieto-Alhambra, et al (BMJ 2011; 343 doi: 10.1136/bmj.d7222 (Published 6 December 2011)
Cite this as: BMJ 2011;343:d7222 ) tested whether bisphosphonate use is related to improved implant survival after total arthroplasty of the knee or hip using a Population based retrospective cohort study involving all patients undergoing primary total arthroplasty of the knee (n=18 726) or hip (n=23 269) in 1986-2006 within the United Kingdom’s General Practice Research Database, after excluding patients with a history of hip fracture before surgery or rheumatoid arthritis, and individuals younger than 40 years at surgery. Of 41 995 patients undergoing primary hip or knee arthroplasty, they identified 1912 bisphosphonate users, who had a lower rate of revision at five years than non-users (0.93% (95% CI 0.52% to 1.68%) v 1.96% (1.80% to 2.14%)). Implant survival was significantly longer in bisphosphonate users than in non-users in propensity adjusted models (hazard ratio 0.54 (0.29 to 0.99); P=0.047) and had an almost twofold increase in time to revision after hip or knee arthroplasty (time ratio 1.96 (1.01 to 3.82)). Assuming 2% failure over five years, we estimated that the number to treat to avoid one revision was 107 for oral bisphosphonates. In patients undergoing lower limb arthroplasty, bisphosphonate use was associated with an almost twofold increase in implant survival time. These findings require replication and testing in experimental studies for confirmation.

Association of Antenatal Corticosteroids With Mortality and Neurodevelopmental Outcomes Among Infants Born at 22 to 25 Weeks' Gestation
W alde mar A. Carlo, et al (JAMA. 2011;306(21):2348-2358. doi: 10.1001/jama.2011.1752 ) determined if use of antenatal corticosteroids is associated with improvement in major outcomes for infants born at 22 and 23 weeks' gestation They analysed data collected prospectively on inborn infants with a birth weight between 401 g and 1000 g (N = 10 541) born at 22 to 25 weeks' gestation between I/ 1993, and XII/ 2009, at 23 academic perinatal centers in the United States. Certified examiners unaware of exposure to antenatal corticosteroids performed follow-up examinations on 4924 (86.5%) of the infants born between 1993 and 2008 who survived to 18 to 22 months. Death or neurodevelopmental impairment at 18 to 22 months was significantly lower for infants who had been exposed to antenatal corticosteroids and were born at 23 weeks' gestation (83.4% with exposure to antenatal corticosteroids vs 90.5% without exposure; AOR, 0.58 [95% CI, 0.42-0.80]), at 24 weeks' gestation (68.4% with exposure to antenatal corticosteroids vs 80.3% without exposure; AOR, 0.62 [95% CI, 0.49-0.78]), and at 25 weeks' gestation (52.7% with exposure to antenatal corticosteroids vs 67.9% without exposure; AOR, 0.61 [95% CI, 0.50-0.74]) but not in those infants born at 22 weeks' gestation (90.2% with exposure to antenatal corticosteroids vs 93.1% without exposure; AOR, 0.80 [95% CI, 0.29-2.21]). If the mothers had received antenatal corticosteroids, the following events occurred significantly less in infants born at 23, 24, and 25 weeks' gestation: death by 18 to 22 months; hospital death; death, intraventricular hemorrhage, or periventricular leukomalacia; and death or necrotizing enterocolitis. For infants born at 22 weeks' gestation, the only outcome that occurred significantly less was death or necrotizing enterocolitis (73.5% with exposure to antenatal corticosteroids vs 84.5% without exposure; AOR, 0.54 [95% CI, 0.30-0.97]).
Conclusion Among infants born at 23 to 25 weeks' gestation, antenatal exposure to corticosteroids compared with nonexposure was associated with a lower rate of death or neurodevelopmental impairment at 18 to 22 months.

Statin prescriptions and breast cancer recurrence risk: a danish nationwide prospective cohort study.
Ahern TP, et al (J Natl Cancer Inst. 2011 Oct 5;103(19):1461-8. Epub 2011 Aug 2) conducted a nationwide, population-based prospective cohort study of all female residents in Denmark diagnosed with stage I-III invasive breast carcinoma who were reported to the Danish Breast Cancer Cooperative Group registry between 1996 and 2003 (n = 18 769). Women were followed for a median of 6.8 years after diagnosis. Prescriptions for lipophilic and hydrophilic statins were ascertained from the national electronic pharmacy database. Associations between statin prescriptions and breast cancer recurrence were estimated with generalized linear models and Cox proportional hazards regression with adjustment for age and menopausal status at diagnosis; histological grade; estrogen receptor status; receipt of adjuvant therapy; type of primary surgery received; pre-diagnosis hormone replacement therapy; and co-prescriptions of aspirin, angiotensin-converting enzyme inhibitors, nonsteroidal anti-inflammatory drugs, or anticoagulants. Most prescriptions for lipophilic statins in the study population were for simvastatin. Exclusive simvastatin users experienced approximately 10 fewer breast cancer recurrences per 100 women after 10 years of follow-up (adjusted 10-year risk difference = -0.10, 95% confidence interval = -0.11 to -0.08), compared with women who were not prescribed a statin. Exclusive hydrophilic statin users had approximately the same risk of breast cancer recurrence as women not prescribed a statin over follow-up (adjusted 10-year risk difference = 0.05, 95% confidence interval = -0.01 to 0.11). Conclusions Simvastatin, a highly lipophilic statin, was associated with a reduced risk of breast cancer recurrence among Danish women diagnosed with stage I-III breast carcinoma, whereas no association between hydrophilic statin use and breast cancer recurrence was observed.

Adherence to a Low-Risk, Healthy Lifestyle and Risk of Sudden Cardiac Death (SCD) Among Women...
Chiuve, et al (JAMA. 2011;306(1):62-69. doi: 10.1001/jama.2011.907) estimated the degree to which adherence to a healthy lifestyle may lower the risk of SCD among women using a prospective cohort study of 81 722 US women in the Nurses' Health Study from June 1984 to June 2010. Lifestyle factors were assessed via questionnaires every 2 to 4 years. A low-risk lifestyle was defined as not smoking, body mass index of less than 25, exercise duration of 30 minutes/day or longer, and top 40% of the alternate Mediterranean diet score, which emphasizes high intake of vegetables, fruits, nuts, legumes, whole grains, and fish and moderate intake of alcohol. There were 321 cases of SCD (defined as death occurring within 1 hour after symptom onset without evidence of circulatory collapse) during 26 years of follow-up. Women were a mean age of 72 years at the time of the SCD event. Compared with women with 0 low-risk factors, the multivariable relative risk of SCD was 0.54 (95% CI, 0.34-0.86) for women with 1 low-risk factor, 0.41 (95% CI, 0.25-0.65) for 2 low-risk factors, 0.33 (95% CI, 0.20-0.54) for 3 low-risk factors, and 0.08 (95% CI, 0.03-0.23) for 4 low-risk factors. The proportion of SCD attributable to smoking, inactivity, overweight, and poor diet was 81% (95% CI, 52%-93%). Among women without clinically diagnosed coronary heart disease, the percentage of population attributable risk was 79% (95% CI, 40%-93%).

A total of 4560 women (median age 62.5 years, median Gail risk score was 2.3%) were randomly assigned to either exemestane or placebo. At a median follow-up of 35 months, 11 invasive breast cancers were detected in those given exemestane and in 32 of those given placebo, with a 65% relative reduction in the annual incidence of invasive breast cancer (0.19% vs. 0.55%; HR, 0.35; 95% [CI], 0.18 to 0.70; P=0.002). The annual incidence of invasive plus noninvasive (ductal carcinoma in situ) breast cancers was 0.35% on exemestane and 0.77% on placebo (HR, 0.47; 95% CI, 0.27 to 0.79; P=0.004). Adverse events occurred in 88% of the exemestane group and 85% of the placebo group (P=0.003), with no significant differences between the two groups in terms of skeletal fractures, cardiovascular events, other cancers, or treatment-related deaths. Minimal quality-of-life differences were observed.
Conclusions: Exemestane significantly reduced invasive breast cancers in postmenopausal women who were at moderately increased risk for breast cancer.

Freeman, et al. estimated the duration of moderate-to-severe menopausal hot flushes and identified potential risk factors for hot flush duration using “The Penn Ovarian Aging Study cohort”, which was monitored for 13 years. Hot flushes were evaluated at 9-month to 12-month intervals through in-person interviews. The primary outcome was the duration of moderate-to-severe hot flushes estimated by survival analysis (n=259). Potential risk factors included menopausal stage, age, race, reproductive hormone levels, body mass index (BMI), and current smoking. A secondary analysis included women who reported any hot flushes (n=349). The median duration of moderate-to-severe hot flushes was 10.2 years and was strongly associated with menopausal stage at onset. Hot flushes that started near entry into the menopause transition had a median duration greater than 11.57 years; onset in the early transition stage had a median duration of 7.35 years (95% CI 4.94–8.89; P<.001); and onset in the late transition to postmenopausal stages had a median duration of 3.84 years (95% CI 1.77–5.52; P<.001). The most common ages at onset of moderate-to-severe hot flushes were 45–49 years (median duration, 8.1 years; 95% CI 5.12–9.28). African American women had a longer duration of hot flushes than white women in adjusted analysis. They concluded that median duration of hot flushes considerably exceeded the timeframe that is generally accepted in clinical practice. The identified risk factors, particularly menopausal stage, race, and BMI, are important to consider in individualizing treatment and evaluating the risk-to-benefit ratio of hormones and other therapies.

Anterior Colporrhaphy versus Transvaginal Mesh for Pelvic-Organ Prolapse
Daniel Altman, et al for the Nordic Transvaginal Mesh Group (N Engl J Med 2011; 364:1826-1836May 12, 2011)
Daniel Altman, et al. conducted a multicenter, parallel-group, randomized, controlled trial, comparing the use of a trocar-guided, transvaginal polypropylene-mesh repair kit with traditional colporrhaphy in women with prolapse of the anterior vaginal wall (cystocele). The primary outcome was a composite of the objective anatomical designation of stage 0 (no prolapse) or 1 (position of the anterior vaginal wall more than 1 cm above the hymen), according to the Pelvic Organ Prolapse Quantification system, and the subjective absence of symptoms of vaginal bulging 12 months after the surgery. Of 389 women who were randomly assigned to a study treatment, 200 underwent prolapse repair with the transvaginal mesh kit and 189 underwent traditional colporrhaphy. At 1 year, the primary outcome was significantly more common in the women treated with transvaginal mesh repair (60.8%) than in those who underwent colporrhaphy (34.5%) (absolute difference, 26.3 percentage points; 95% confidence interval, 15.6 to 37.0). The surgery lasted longer and the rates of intraoperative hemorrhage were higher in the mesh-repair group than in the colporrhaphy group (P<0.001 for both comparisons). Rates of bladder perforation were 3.5% in the mesh-repair group and 0.5% in the colporrhaphy group (P=0.07), and the respective rates of new stress urinary incontinence after surgery were 12.3% and 6.3% (P=0.05). Surgical reintervention to correct mesh exposure during follow-up occurred in 3.2% of 186 patients in the mesh-repair group. As compared with anterior colporrhaphy, use of a standardized, trocar-guided mesh kit for cystocele repair resulted in higher short-term rates of successful treatment but also in higher rates of surgical complications and postoperative adverse events.

Bisphosphonate Use and Atypical Fractures of the Femoral Shaft
Jörg Schilcher, et al (N Engl J Med 2011; 364:1728-1737May 5, 2011)
Jörg Schilcher, et al reviewed radiographs of 1234 of the 1271 women who had a subtrochanteric or shaft fracture and identified 59 patients with atypical fractures. Data on medications and coexisting conditions were obtained from national registries. The relative and absolute risk of atypical fractures associated with bisphosphonate use was estimated by means of a nationwide cohort analysis. The 59 case patients were also compared with 263 control patients who had ordinary subtrochanteric or shaft fractures The age-adjusted relative risk of atypical fracture was 47.3 (95% CI, 25.6 to 87.3) in the cohort analysis. The increase in absolute risk was 5 cases per 10,000 patient-years (95% CI, 4 to 7). A total of 78% of the case patients and 10% of the controls had received bisphosphonates, corresponding to a multivariable-adjusted odds ratio of 33.3 (95% CI, 14.3 to 77.8). The risk was independent of coexisting conditions and of concurrent use of other drugs with known effects on bone. The duration of use influenced the risk (odds ratio per 100 daily doses, 1.3; 95% CI, 1.1 to 1.6). After drug withdrawal, the risk diminished by 70% per year since the last use (odds ratio, 0.28; 95% CI, 0.21 to 0.38). The authors concluded that these population-based nationwide analyses may be reassuring for patients who receive bisphosphonates. Although there was a high prevalence of current bisphosphonate use among patients with atypical fractures, the absolute risk was small. (Funded by the Swedish Research Council.)

The postintervention risk (annualized rate) for coronary hearth disease (CHD) among women assigned to CEE was 0.64% compared with 0.67% in the placebo group (HR, 0.97; 95%CI, 0.75-1.25), 0.26% vs 0.34%, respectively, for breast cancer (HR, 0.75; 95% CI, 0.51-1.09), and 1.47% vs 1.48%, respectively, for total mortality (HR, 1.00; 95% CI, 0.84-1.18). The risk of stroke was no longer elevated during the postintervention follow-up period and was 0.36% among women receiving CEE compared with 0.41% in the placebo group (HR, 0.89; 95% CI, 0.64-1.24), the risk of deep vein thrombosis was lower at 0.17% vs 0.27%, respectively (HR, 0.63; 95% CI, 0.41-0.98), and the risk of hip fracture did not differ significantly and was 0.36% vs 0.28%, respectively (HR, 1.27; 95% CI, 0.88-1.82). Over the entire follow-up, lower breast cancer incidence in the CEE group persisted and was 0.27% compared with 0.35% in the placebo group (HR, 0.77; 95% CI, 0.62-0.95). Health outcomes were more favorable for younger compared with older women for CHD (P = .05 for interaction), total myocardial infarction (P = .007 for interaction), colorectal cancer (P = .04 for interaction), total mortality (P = .04 for interaction), and global index of chronic diseases (P = .009 for interaction).
Conclusions: Among postmenopausal women with prior hysterectomy followed up for 10.7 years, CEE use for a median of 5.9 years was not associated with an increased or decreased risk of CHD, deep vein thrombosis, stroke, hip fracture, colorectal cancer, or total mortality. A decreased risk of breast cancer persisted.

Preventive therapy for breast cancer: a consensus statement (Jack Cuzick et al The Lancet Oncology, Early Online Publication, 28 March 2011 doi:10.1016/S1470-2045(11)70030-4)(doi:10.1016/S0140-6736(08)61345-8)
A group of breast cancer experts met to develop a consensus statement on breast cancer prevention. They agreed that the term chemoprevention is inappropriate and suggested that the term preventive therapy better represents this feature of management. Two selective oestrogen-receptor modulators—tamoxifen and raloxifene—are so far the only medical options approved by the US Food and Drug Administration for preventive therapy. Of these tamoxifen has greater efficacy and can be used in premenopausal women, but raloxifene has fewer side-effects. Two newer drugs in this class, lasofoxifene and arzoxifene, also show efficacy and possibly a better overall risk-benefit profile, but need further assessment. Aromatase inhibitors might be more efficacious, and results of prevention trials are eagerly awaited. Newer agents, notably bisphosphonates and metformin, have shown promise in observational studies and need to be assessed in randomised prevention trials. Other agents, such as aspirin, other non-steroidal anti-inflammatory drugs, COX-2 inhibitors, retinoids, rexinoids, and dietary components have limited effects or are in the early phases of investigation. New contralateral tumours in women with breast cancer might be generally useful as a model for prevention, as has been seen for tamoxifen. If valid such a model would facilitate the design of simpler, cheaper, and better-focused trials for assessing new agents.

N° 701 TOPIC: VITAMIN D AND WOMEN’S HEALTH
Vitamin D and Prevention of Cancer — Ready for Prime Time? (JE. Manson, ST. Mayne, SK. Clinton. March 23, 2011 (10.1056/NEJMp1102022)
Despite biologic plausibility and widespread enthusiasm, the American Institute of Medicine (IOM) committee found that the evidence that vitamin D reduces cancer incidence and related mortality was inconsistent and inconclusive as to causality. Indeed, for instance 3 vitamin D trials, including one trial comparing a combination of vitamin D with calcium to calcium alone, have assessed the occurrence of newly diagnosed cancers or cancer mortality as secondary outcomes, but the results were null. New trials assessing moderate-to-high-dose vitamin D supplementation for cancer prevention are in progress and should provide additional information within 5 to 6 years. Although future research may demonstrate clear benefits of vitamin D related to cancer and other nonskeletal health outcomes, and possibly support higher intake requirements, the existing evidence falls short.

Cigarette Smoking and the Incidence of Breast Cancer
Fei Xue, et al ( Arch Intern Med. 2011;171(2):125-133. doi:10.1001/archinternmed.2010.503) evaluated the effect of smoking on breast cancer (BC) incidence in the prospective cohort study of 111 140 participants of the Nurses' Health Study from 1976 to 2006 for active smoking and 36 017 women from 1982 to 2006 for passive smoking. During 3 005 863 person-years of follow-up, 8772 incident cases of invasive BC were reported. After adjustment for potential confounders, the HR of BC was 1.06% (95%CI, 1.01%-1.10%) for ever smokers relative to never smokers. Breast cancer incidence was associated with a higher quantity of current (P for trend = .02) and past (P for trend = .003) smoking, younger age at smoking initiation (P for trend = .01), longer duration of smoking (P for trend = .01), and more pack-years of smoking (P for trend = .005). Premenopausal smoking was associated with a slightly higher incidence of BC (HR, 1.11; 95% CI, 1.07-1.15 for every increase of 20 pack-years), especially smoking before first birth (1.18; 1.10-1.27 for every increase of 20 pack-years). Conversely, the direction of the association between postmenopausal smoking and BC was inverse (0.93; 0.85-1.02 for every increase of 20 pack-years). Passive smoking in childhood or adulthood was not associated with BC risk.
Conclusion Active smoking, especially smoking before the first birth, may be associated with a modest increase in the risk of BC.

Axillary Dissection vs No Axillary Dissection in Women With Invasive Breast Cancer and Sentinel Node Metastasis: A Randomized Clinical Trial
Giuliano, et al (JAMA. 2011;305(6):569-575. doi: 10.1001/jama.2011.90) determined the effects of complete axillary lymph node dissection (ALND) on survival of patients with sentinel lymph node (SLN) metastasis of breast cancer in a phase 3 noninferiority multicenter involving women with clinical T1-T2 invasive breast cancer, no palpable adenopathy, and 1 to 2 SLNs containing metastases identified by frozen section, touch preparation, or hematoxylin-eosin staining on permanent section. All patients underwent lumpectomy and tangential whole-breast irradiation. Those with SLN metastases identified by SLND were randomized to undergo ALND or no further axillary treatment. Those randomized to ALND underwent dissection of 10 or more nodes. Clinical and tumor characteristics were similar between 445 patients randomized to ALND and 446 randomized to SLND alone. However, the median number of nodes removed was 17 with ALND and 2 with SLND alone. At a median follow-up of 6.3 years (last follow-up, March 4, 2010), 5-year overall survival was 91.8% (95% CI, 89.1%-94.5%) with ALND and 92.5% (95% CI, 90.0%-95.1%) with SLND alone; 5-year disease-free survival was 82.2% (95% CI, 78.3%-86.3%) with ALND and 83.9% (95% CI, 80.2%-87.9%) with SLND alone. The hazard ratio for treatment-related overall survival was 0.79 (90% CI, 0.56-1.11) without adjustment and 0.87 (90% CI, 0.62-1.23) after adjusting for age and adjuvant therapy.
The authors concluded that among patients with limited SLN metastatic breast cancer treated with breast conservation and systemic therapy, the use of SLND alone compared with ALND did not result in inferior survival.

Gulisa Turashvili et al (Modern Pathology (2011) 24, 64–81; doi:10.1038/modpathol.2010.189; published online 17 September 2010) http://www.nature.com/modpathol/journal/v24/n1/full/modpathol2010189a.html reported an analysis of P-cadherin expression as a prognostic biomarker in a 3992 case tissue microarray series of breast cancer. P-cadherin expression was evaluated using immunohistochemistry. Median follow-up was 12.5 years. P-cadherin was expressed in 34.8% of cases. P-cadherin staining was strongly associated with HER2+ and basal carcinoma subtypes (P<0.0005). P-cadherin-positive patients showed significantly poorer short-term (0–10 years) overall survival, disease-specific survival, distant relapse-free interval, and locoregional relapse-free interval in univariable models (P<0.05). In multivariable Cox models containing standard clinical covariates and cancer subtypes, P-cadherin did not show independent prognostic value. P-cadherin expression was positively associated with histological grade, chemotherapy, Ki-67, EGFR, CK5/6, p53, YB-1, and HER2 expression (P<0.002), and negatively associated with age at diagnosis, ER, PR, and Bcl-2 expression (P<0.0005). This study shows the value of P-cadherin as a marker of poor prognosis. The large sample size of this series clarifies contradictory findings of many smaller studies. P-cadherin positivity is associated with high-grade tumor subtypes and well-established markers of poor prognosis, and may represent a promising antibody therapeutic target.

Sensitivity of transvaginal ultrasound screening for endometrial cancer in postmenopausal women: a case-control study within the UKCTOCS cohort
In this paper, Ian Jacobs et al from United Kingdom Collaborative Trial of Ovarian Cancer Screening (UKCTOCS) (The Lancet Oncology, Early Online Publication, 13 December 2010 doi:10.1016/S1470-2045(10)70268-0) analysed whether Transvaginal ultrasound (TVS) is a possible screening test for endometrial cancer. They did a nested case-control study of postmenopausal women who underwent (TVS) between April 17, 2001, and Sept 29, 2005. Endometrial thickness and endometrial abnormalities were recorded, and follow-up, through national registries and a postal questionnaire, documented the diagnosis of endometrial cancer. The primary outcome measure was endometrial cancer and atypical endometrial hyperplasia (AEH). Performance characteristics of endometrial thickness and abnormalities for detection of endometrial cancer within 1 year of TVS were calculated. Epidemiological variables were used to develop a logistic regression model and assess a screening strategy for women at higher risk. 48 230 women underwent TVS in the UKCTOCS prevalence screen. 9078 women were ineligible because they had undergone a hysterectomy and 2271 because their endometrial thickness had not been recorded; however, 157 of these women had an endometrial abnormality on TVS and were included in the analysis. Median follow-up was 5•11 years (IQR 4•05—5•95). 136 women with endometrial cancer or AEH within 1 year of TVS were included in the primary analysis. The optimum endometrial thickness cutoff for endometrial cancer or AEH was 5•15 mm, with sensitivity of 80•5% (95% CI 72•7—86•8) and specificity of 86•2% (85•8—86•6). Sensitivity and specificity at a 5 mm or greater cutoff were 80•5% (72•7—86•8) and 85•7% (85•4—86•2); for women with a 5 mm or greater cutoff plus endometrial abnormalities, the sensitivity and specificity were 85•3% (78•2—90•8) and 80•4% (80•0—80•8), respectively. For a cutoff of 10 mm or greater, sensitivity and specificity were 54•1% (45•3—62•8) and 97•2% (97•0—97•4). When our analysis was restricted to the 96 women with endometrial cancer or AEH who reported no symptoms of postmenopausal bleeding at the UKCTOCS scan before diagnosis and had an endometrial thickness measurement available, a cutoff of 5 mm achieved a sensitivity of 77•1% (67•8—84•3) and specificity of 85•8% (85•7—85•9). The logistic regression model identified 25% of the population as at high risk and 39•5% of endometrial cancer or AEH cases were identified within this high risk group. In this high-risk population, a cutoff at 6•75 mm achieved sensitivity of 84•3% (71•4—93•0) and specificity of 89•9% (89•3—90•5).
Interpretation
These findings show that TVS screening for endometrial cancer has good sensitivity in postmenopausal women. The burden of diagnostic procedures and false-positive results can be reduced by limiting screening to a higher-risk group. The role of population screening for endometrial cancer remains uncertain, but these findings are of immediate value in the management of increased endometrial thickness in postmenopausal women undergoing pelvic scans for reasons other than vaginal bleeding.

Detection of lung, breast, colorectal, and prostate cancers from exhaled breath using a single array of nanosensors
G Peng et al (British Journal of Cancer (2010) 103, 542–551. doi:10.1038/sj.bjc.6605810 www.bjcancer.com) investigated the ability of a nanosensor array to discriminate between the emission of volatile organic compounds (VOCs) (breath VOCs) that characterise healthy states and the most widespread cancer states in the developed world: lung, breast, colorectal, and prostate cancers. Exhaled alveolar breath was collected from 177 volunteers aged 20–75 years (patients with lung, colon, breast, and prostate cancers and healthy controls). The healthy population was healthy according to subjective patient's data. The breath of volunteers was examined by a tailor-made array of cross-reactive nanosensors based on organically functionalised gold nanoparticles and gas chromatography linked to the mass spectrometry technique (GC-MS). The results showed that the nanosensor array could differentiate between ‘healthy’ and ‘cancerous’ breath, and, furthermore, between the breath of patients having different cancer types. Moreover, the nanosensor array could distinguish between the breath patterns of different cancers in the same statistical analysis, irrespective of age, gender, lifestyle, and other confounding factors. The GC-MS results showed that each cancer could have a unique pattern of VOCs, when compared with healthy states, but not when compared with other cancer types.

Baer et al Am J Epidemiol. 2010 Dec 6. [Epub ahead of print] examined associations of lifestyle and dietary factors with all-cause and cause-specific mortality among 50,112 participants in the Nurses' Health Study. There were 4,893 deaths between 1986 and 2004: 1,026 from cardiovascular disease, 931 from smoking-related cancers, 1,430 from cancers not related to smoking, and 1,506 from all other causes. Age, body mass index at age 18 years, weight change, height, current smoking and pack-years of smoking, glycemic load, cholesterol intake, systolic blood pressure and use of blood pressure medications, diabetes, parental myocardial infarction before age 60 years, and time since menopause were directly related to all-cause mortality, whereas there were inverse associations for physical activity and intakes of nuts, polyunsaturated fat, and cereal fiber. Moderate alcohol consumption was associated with decreased mortality. A model that incorporated differences in the associations of some risk factors with specific causes of death had a significantly better fit compared with a model in which all risk factors had common associations across all causes. In the future, this new model may be used to identify individuals at increased risk of mortality.

N° 693 TOPIC: OSTEOPOROSIS AND BREAST CANCER
Two studies published today in Nature show how progestin can cause breast cancer in mice by activating the protein RANKL. The studies highlight a potential role for RANKL inhibition in the management of proliferative breast disease.
Daniel Schramek et al (Nature 468, 98-102, 4 November 2010) observed that the in vivo administration of MPA triggers massive induction of the key osteoclast differentiation factor RANKL (receptor activator of NF-κB ligand) in mammary-gland epithelial cells. Genetic inactivation of the RANKL receptor RANK in mammary-gland epithelial cells prevents MPA-induced epithelial proliferation, impairs expansion of the CD49fhi stem-cell-enriched population, and sensitizes these cells to DNA-damage-induced cell death. Deletion of RANK from the mammary epithelium results in a markedly decreased incidence and delayed onset of MPA-driven mammary cancer. These data show that the RANKL/RANK system controls the incidence and onset of progestin-driven breast cancer.
Eva Gonzalez-Suarez (Nature 468, 103-107 (4 November 2010) | doi:10.1038/nature09495) showed that RANK and RANKL are expressed within normal, pre-malignant and neoplastic mammary epithelium, and using complementary gain-of-function (mouse mammary tumour virus (MMTV)-RANK transgenic mice) and loss-of function (pharmacological inhibition of RANKL) approaches, define a direct contribution of this pathway in mammary tumorigenesis. Accelerated pre-neoplasias and increased mammary tumour formation were observed in MMTV-RANK transgenic mice after multiparity or treatment with carcinogen and hormone (progesterone). Reciprocally, selective pharmacological inhibition of RANKL attenuated mammary tumour development not only in hormone- and carcinogen-treated MMTV-RANK and wild-type mice, but also in the MMTV-neu transgenic spontaneous tumour model. The reduction in tumorigenesis upon RANKL inhibition was preceded by a reduction in pre-neoplasias as well as rapid and sustained reductions in hormone- and carcinogen-induced mammary epithelial proliferation and cyclin D1 levels. Collectively, these results indicate that RANKL inhibition is acting directly on hormone-induced mammary epithelium at early stages in tumorigenesis, and the permissive contribution of progesterone to increased mammary cancer incidence is due to RANKL-dependent proliferative changes in the mammary epithelium.

Effect of Music-Based Multitask Training on Gait, Balance, and Fall Risk in Elderly People
Andrea Trombetti, et al (Arch Intern Med. Published online November 22, 2010. doi:10.1001/archinternmed.2010.446) conducted a 12-month RCT involving 134 community-dwelling individuals older than 65 years, who are at increased risk of falling. They were randomly assigned to an intervention group (n = 66) or a delayed intervention control group scheduled to start the program 6 months later (n = 68). The intervention was a 6-month multitask exercise program performed to the rhythm of piano music. Change in gait variability under dual-task condition from baseline to 6 months was the primary end point. Secondary outcomes included changes in balance, functional performances, and fall risk.
At 6 months, Balance and functional tests improved compared with the control group. And there were fewer falls in the intervention group (incidence rate ratio, 0.46; 95%CI, 0.27-0.79) and a lower risk of falling (RR, 0.61; 95% CI, 0.39-0.96). Similar changes occurred in the delayed intervention control group during the second 6-month period with intervention. The benefit of the intervention on gait variability persisted 6 months later.

Cuzick et al (The Lancet Oncology, Early Online Publication, 17 November 2010
doi:10.1016/S1470-2045(10)70257-6) report the long-term outcomes after a median follow-up of 120 months of the The Arimidex, Tamoxifen, Alone or in Combination (ATAC) trial comparing the efficacy and safety of anastrozole (1 mg) with tamoxifen (20 mg), both given orally every day for 5 years, as adjuvant treatment for postmenopausal women with early-stage breast cancer.
The primary endpoints were the disease-free survival, and the secondary endpoints: time to recurrence, time to distant recurrence, incidence of new contralateral breast cancer, overall survival, and death with or without recurrence in all randomised patients (anastrozole n=3125, tamoxifen n=3116) and hormone-receptor-positive patients (anastrozole n=2618, tamoxifen n=2598). After treatment completion, they continued to collect data on fractures and serious adverse events in a masked fashion (safety population: anastrozole n=3092, tamoxifen n=3094).
There were 24 522 woman-years of follow-up in the anastrozole group and 23 950 woman-years in the tamoxifen group. In the full study population, there were significant improvements in the anastrozole group compared with the tamoxifen group for disease-free survival (HR] 0•91, 95% CI 0•83—0•99; p=0•04), time to recurrence (0•84, 0•75—0•93; p=0•001), and time to distant recurrence (0•87, 0•77—0•99; p=0•03). For hormone-receptor-positive patients, the results were also significantly in favour of the anastrozole group for disease-free survival (HR 0•86, 95% CI 0•78—0•95; p=0•003), time to recurrence (0•79, 0•70—0•89; p=0•0002), and time to distant recurrence (0•85, 0•73—0•98; p=0•02). In hormone-receptor-positive patients, absolute differences in time to recurrence between anastrozole and tamoxifen increased over time (2•7% at 5 years and 4•3% at 10 years) and recurrence rates remained significantly lower on anastrozole than tamoxifen after treatment completion (HR 0•81, 95% CI 0•67—0•98; p=0•03), although the carryover benefit was smaller after 8 years. There was weak evidence of fewer deaths after recurrence with anastrozole compared with tamoxifen treatment in the hormone-receptor-positive subgroup (HR 0•87, 95% CI 0•74—1•02; p=0•09), but there was little difference in overall mortality (0•95, 95% CI 0•84—1•06; p=0•4).
Fractures were more frequent during active treatment in patients receiving anastrozole than those receiving tamoxifen (451 vs 351; OR 1•33, 95% CI 1•15—1•55; p<0•0001), but were similar in the post-treatment follow-up period (110 vs 112; OR 0•98, 95% CI 0•74—1•30; p=0•9). Treatment-related serious adverse events were less common in the anastrozole group than the tamoxifen group (223 anastrozole vs 369 tamoxifen; OR 0•57, 95% CI 0•48—0•69; p<0•0001), but were similar after treatment completion (66 vs 78; OR 0•84, 95% CI 0•60—1•19; p=0•3). No differences in non-breast cancer causes of death were apparent and the incidence of other cancers was similar between groups (425 vs 431) and continue to be higher with anastrozole for colorectal (66 vs 44) and lung cancer (51 vs 34), and lower for endometrial cancer (six vs 24), melanoma (eight vs 19), and ovarian cancer (17 vs 28). No new safety concerns were reported.

Interpretation
These data confirm the long-term superior efficacy and safety of anastrozole over tamoxifen as initial adjuvant therapy for postmenopausal women with hormone-sensitive early breast cancer.

Epub 2010 Jun 21) evaluated the association between oral bisphosphonate use and invasive breast cancer was in postmenopausal women enrolled onto the WHI. Of the 154,768 participants, 2,816 were oral bisphosphonate users at entry (90% alendronate, 10% etidronate). As calculated hip fracture risk score was significantly associated with both BMD (regression line = 0.79 to 0.0478 log predicted fracture; P < .001; r = 0.43) and breast cancer incidence (P = .03), this variable was incorporated into regression analyses to adjust for BMD difference between users and nonusers of bisphopshonate. After 7.8 mean years of follow-up (standard deviation, 1.7), invasive breast cancer incidence was lower in bisphosphonate users (hazard ratio [HR], 0.68; 95% CI, 0.52 to 0.88; P < .01) as was incidence of estrogen receptor (ER) -positive invasive cancers (HR, 0.70; 95% CI, 0.52 to 0.94, P = .02). A similar but not significant trend was seen for ER-negative invasive cancers. The incidence of ductal carcinoma in situ was higher in bisphosphonate users (HR, 1.58; 95% CI, 1.08 to 2.31; P = .02).

Leslie, et al (Ann Intern Med November 2, 2010 vol. 153 no. 9 580-586) assessed the changes in physician prescribing behavior after introduction of absolute 10-year fracture risk reporting in Manitoba, Canada. Absolute fracture risk reporting reclassified more women (32.7%) into lower-risk categories than into higher-risk categories (10%). This effect was more prominent in women younger than 65 years. Fewer women per physician were prescribed osteoporosis drugs after introduction of absolute fracture risk reporting. The absolute fracture risk reporting system was associated with an overall reduction in osteoporosis medications dispensed (adjusted absolute reduction, 9.0 percentage points [95% CI, 3.9 to 14.2 percentage points]; relative reduction, 21.3% [CI, 9.2% to 33.5%]; P < 0.001). The reduction was attributed to fewer drugs dispensed to women at low and moderate risk for fracture.

N° 688 TOPIC: POI
Schmidt et al J Clin Endocrinol Metab.2010 Nov 3. [Epub ahead of print] characterized the prevalence of psychiatric disorders and the timing of onset of clinically significant depression relative to both the diagnosis of primary ovarian insufficiency (POI) and the onset of menstrual irregularity in women with POI. They conducted a cross-sectional clinic-based study: A total of 174 women with spontaneous 46, XX POI and 100 women with Turner syndrome participated in the study. Lifetime histories of depression in POI exceeded rates of depression reported in women with Turner syndrome and community-based samples of women (P < 0.001). The onset of depression frequently preceded the diagnosis of POI but occurred after the onset of menstrual irregularity. Analyses standardizing the periods of risk for depression showed that similar numbers of depressions occurred before and after these events. The authors concluded that POI is associated with an increased lifetime risk for major depression. Attention to the presence of depression in POI should become an important part of the care for these women. The onset of depression frequently occurs after signs of altered ovarian function but before the diagnosis of POI. Thus, in some women the association between POI and depression suggests an overlapping pathophysiology rather than a causal relationship.
