RESUMO
RESEARCH QUESTION: What is the influence of ethnicity on the outcome of ovulation induction with clomifene citrate in women with polycystic ovary syndrome (PCOS)? DESIGN: This was a retrospective cohort study. In total, 420 women diagnosed with PCOS who were of Northern European, Mediterranean, African, South-East Asian or South American descent, and who started ovulation induction treatment with clomifene citrate, were included. All women were treated with clomifene citrate according to a standardized treatment regimen. The minimal effective dose of clomifene citrate and prevalence of clomifene resistance (CRA) were assessed, and the chance of becoming ovulatory was predicted. RESULTS: Differences were observed in body mass index (Pâ¯=â¯0.008), waist circumference (P = 0.036) and serum LH, insulin and androgen concentrations (all P < 0.001) in women of different ethnicities with PCOS. Compared with women of Northern European descent, the minimal effective dose of clomifene citrate in women of other ethnic groups was not significantly different. The prevalence of CRA (P = 0.574) was similar in all ethnic groups A similar chance of ovulation (P = 0.504) was predicted for the different ethnic groups. CONCLUSIONS: This is the first study aiming to link ethnicity to ovulation induction outcome in PCOS. Although women of different ethnicities who have PCOS exhibit a variation in phenotypic expression, there do not appear to be differences in the prevalence of clomifene-resistant anovulation or the minimal effective dose of clomifene citrate. Furthermore, a prediction model revealed no significant differences in the predicted chance of ovulation. A larger cohort is needed to validate these findings.

RESUMO
Polycystic ovary syndrome (PCOS) is a disorder characterized by hyperandrogenism, ovulatory dysfunction and polycystic ovarian morphology. Affected women frequently have metabolic disturbances including insulin resistance and dysregulation of glucose homeostasis. PCOS is diagnosed with two different sets of diagnostic criteria, resulting in a phenotypic spectrum of PCOS cases. The genetic similarities between cases diagnosed based on the two criteria have been largely unknown. Previous studies in Chinese and European subjects have identified 16 loci associated with risk of PCOS. We report a fixed-effect, inverse-weighted-variance meta-analysis from 10,074 PCOS cases and 103,164 controls of European ancestry and characterisation of PCOS related traits. We identified 3 novel loci (near PLGRKT, ZBTB16 and MAPRE1), and provide replication of 11 previously reported loci. Only one locus differed significantly in its association by diagnostic criteria; otherwise the genetic architecture was similar between PCOS diagnosed by self-report and PCOS diagnosed by NIH or non-NIH Rotterdam criteria across common variants at 13 loci. Identified variants were associated with hyperandrogenism, gonadotropin regulation and testosterone levels in affected women. Linkage disequilibrium score regression analysis revealed genetic correlations with obesity, fasting insulin, type 2 diabetes, lipid levels and coronary artery disease, indicating shared genetic architecture between metabolic traits and PCOS. Mendelian randomization analyses suggested variants associated with body mass index, fasting insulin, menopause timing, depression and male-pattern balding play a causal role in PCOS. The data thus demonstrate 3 novel loci associated with PCOS and similar genetic architecture for all diagnostic criteria. The data also provide the first genetic evidence for a male phenotype for PCOS and a causal link to depression, a previously hypothesized comorbid disease. Thus, the genetics provide a comprehensive view of PCOS that encompasses multiple diagnostic criteria, gender, reproductive potential and mental health.

OBJECTIVES: Contradictory results have been reported regarding the association between polycystic ovary syndrome (PCOS) and cardiovascular disease (CVD). We assessed the cardiometabolic phenotype and prevalence of CVD in middle-aged women with PCOS, compared with age-matched controls from the general population, and estimated 10-year CVD risk and cardiovascular health score. DESIGN: A cross-sectional study. PARTICIPANTS: 200 women aged >45 with PCOS, and 200 age-matched controls. MEASUREMENTS: Anthropometrics, insulin, lipid levels, prevalence of metabolic syndrome and type II diabetes. Ten-year Framingham risk score and the cardiovascular health score were calculated, and carotid intima-media thickness (cIMT) was measured. RESULTS: Mean age was 50.5 years (SD = 5.5) in women with PCOS and 51.0 years (SD = 5.2) in controls. Increased waist circumference, body mass index and hypertension were more often observed in women with PCOS (P < .001). In women with PCOS, the prevalence of type II diabetes and metabolic syndrome was not significantly increased and lipid levels were not different from controls. cIMT was lower in women with PCOS (P < .001). Calculated cardiovascular health and 10-year CVD risk were similar in women with PCOS and controls. CONCLUSIONS: Middle-aged women with PCOS exhibit only a moderately unfavourable cardiometabolic profile compared to age-matched controls, even though they present with an increased BMI and waist circumference. Furthermore, we found no evidence for increased (10-year) CVD risk or more severe atherosclerosis compared with controls from the general population. Long-term follow-up of women with PCOS is necessary to provide a definitive answer concerning long-term risk for CVD.

OBJECTIVE: Women with premature ovarian insufficiency (POI) enter menopause before age 40. Early menopause was associated with increased risk for coronary artery disease (CAD), death from cardiovascular disease and all-cause mortality. We compared the prevalence of CAD between middle-aged women on average 10 years following the initial POI diagnosis, with a population-based cohort. DESIGN: Cross-sectional case-control study. PARTICIPANTS: Women from two Dutch University Medical Centers above 45 years of age previously diagnosed with POI (n = 98) were selected and compared with age- and race-matched controls from the Multi-Ethnic Study of Atherosclerosis (MESA). MEASUREMENTS: The primary outcome was detectable coronary artery calcium (CAC) determined by coronary computed tomography (CCT). RESULTS: Women with POI had significantly higher blood pressure, cholesterol and glucose, despite lower BMI compared to controls. Similar proportions of detectable CAC (CAC score >0 Agatston Units) were observed in women with POI and controls (POI n = 16 (16%), controls n = 52 (18%), P = 0.40 and Padj = 0.93). In women with POI separately, we were not able to identify associations between CVD risk factors and CAC. The following CVD risk factors in controls were positively associated with CAC: age, diabetes mellitus, hypertension and LDL cholesterol. HRT use was negatively associated with CAC in controls. CONCLUSIONS: The presence of CAC did not differ significantly in women with POI around 50 years of age, compared to an age- and race-matched control group. We observe no increased calcified coronary disease in POI patients, despite the presence of unfavourable cardiovascular risk factors in these women.

BACKGROUND: Reproductive disorders, such as polycystic ovary syndrome (PCOS), primary ovarian insufficiency (POI) and hypertensive pregnancy disorders (HPD) like pre-eclampsia (PE), are associated with an increased risk of cardiovascular disease (CVD). Detection of early signs of cardiovascular disease (CVD), as well as identification of risk factors among women of reproductive age which improve cardiovascular risk prediction, is a challenge and current models might underestimate long-term health risks. The aim of this study is to assess cardiovascular disease in patients with a history of a reproductive disorder by low-dose computed tomography (CT). METHODS: Women of 45 - 55 years, who experienced a reproductive disorder (PCOS, POI, HPD), are invited to participate in this multicenter, prospective, cohort study. Women will be recruited after regular cardiovascular screening, including assessment of classical cardiovascular risk factors. CT of the coronary arteries (both coronary artery calcium scoring (CACS), and contrast-enhanced coronary CT angiography (CCTA)) and carotid siphon calcium scoring (CSC) is planned in 300 women with HPD and 300 women with PCOS or POI. In addition, arterial stiffness (non-invasive pulse wave velocity (PWV)) measurement and cell-based biomarkers (inflammatory circulating cells) will be obtained. DISCUSSION: Initial inclusion is focused on women of 45 - 55 years. However, the age range (40 - 45 years and/or ≥ 55 years) and group composition may be adjusted based on the findings of the interim analysis. Participants can potentially benefit from information obtained in this study concerning their current cardiovascular health and expected future risk of cardiovascular events. The results of this study will provide insights in the development of CVD in women with a history of reproductive disorders. Ultimately, this study may lead to improved cardiovascular prediction models and will provide an opportunity for timely adjustment of preventive strategies. Limitations of this study include the possibility of overdiagnosis and the average radiation dose of 3.5 mSv during coronary and carotid siphon CT, although the increased lifetime malignancy risk is negligible.

BACKGROUND AND AIMS: To understand pathophysiological mechanisms underlying migraine as a cardiovascular risk factor, we studied neuropeptide action and endothelial function as measures of peripheral microvascular function in middle-aged women with or without migraine. METHODS: We included women with the endocrine disorder polycystic ovary syndrome (PCOS), a population with supposed elevated cardiovascular risk, with and without comorbid migraine. In 26 women without and 23 women with migraine in the interictal phase (mean age 50.8 ± 2.9 years) local thermal hyperemia (LTH) of the skin of the volar forearm was measured cross-sectionally under control conditions, after inhibition of neuropeptide release by 5% lidocaine/prilocaine (EMLA) cream application, and after inhibition of nitric oxide formation by iontophoresis of NG-monomethyl-l-arginine (L-NMMA). Hereafter, changes in the natural logarithm of the reactive hyperemia index (lnRHI) and augmentation index (AI) during reperfusion after occlusion-derived ischemia were measured. RESULTS: While mean values under control conditions and L-NMMA conditions were similar, migraine patients had a significantly higher mean area of the curve (AUC) of the total LTH response after EMLA application than those without (86.7 ± 26.5% versus 67.9 ± 24.2%; p = 0.014). This was also reflected by a higher median AUC of the plateau phase under similar conditions in women with migraine compared to those without (83.2% (IQR[73.2-109.5]) versus 73.2% (IQR[54.3-92.0]); p = 0.039). Mean changes in lnRHI and AI scores were similar in both groups. CONCLUSIONS: In PCOS patients with migraine, neuropeptide action was lower compared with those without migraine. While larger studies are warranted, these findings provide a potential mechanism supporting previous findings that migraine may be independent from traditional risk factors, including atherosclerosis.

BACKGROUND: Some patients develop troublesome dysphagia after laparoscopic antireflux surgery, and a proportion require further intervention. The management of this problem was evaluated. METHODS: Patients who underwent intervention for dysphagia after laparoscopic fundoplication were identified from a database. Outcomes were prospectively determined from a standardized questionnaire that evaluated symptoms scores for dysphagia for solids and liquids, as well as patient satisfaction with the overall outcome. Outcomes 1 year after reintervention, and at the most recent follow-up were evaluated. RESULTS: From 1994 to 2009, 121 (6.6%) of 1,821 patients who underwent laparoscopic fundoplication for gastroesophageal reflux also underwent endoscopic or surgical reintervention for dysphagia. Of these 121 patients, 56 underwent endoscopic dilatation, and 24 were satisfied with the outcome of dilatation; 18 progressed to surgery, and dysphagia persisted in 14 of them. Overall, 83 patients underwent revisional surgery, and 47 (62.7%) were satisfied with the outcome. Compared to patients who did not undergo any intervention for dysphagia, patients who underwent reintervention had lower satisfaction scores and higher dysphagia scores. CONCLUSIONS: Approximately two thirds of patients with troublesome post-fundoplication dysphagia have a satisfactory outcome following either endoscopic dilatation or revisional surgery. However, approximately one third continue to be troubled by symptoms, despite further intervention.

OBJECTIVE: To determine a cutoff for the Elecsys AMH Plus immunoassay (Roche Diagnostics International Ltd, Rotkreuz, Switzerland) to identify polycystic ovarian morphology (PCOM), a polycystic ovary syndrome (PCOS) criterion. DESIGN: The AMH Protein in Humans for polycystic ovaRian mOrphology DIagnostic TEsting (APHRODITE) study was a retrospective, multicenter, case-control study. The serum antimüllerian hormone (AMH) level was measured using the Elecsys AMH Plus immunoassay. The antral follicle count was determined using transvaginal ultrasound. An AMH cutoff was derived and validated in separate cohorts with cases of PCOS with full phenotype A (oligo/anovulation, hyperandrogenism, and PCOM) versus that with controls. Exploratory analyses of age and PCOS phenotype were performed. SETTING: Not applicable. PATIENT(S): Polycystic ovary syndrome-positive (PCOS A-D per the Rotterdam criteria) and PCOS-negative women aged 25-45 years. INTERVENTION(S): None. MAIN OUTCOME MEASURE(S): A validated cutoff for AMH using the Elecsys AMH Plus assay for PCOM. RESULT(S): In the validation cohort (455 cases and 500 controls), an AMH cutoff of 3.2 ng/mL (23 pmol/L) resulted in a sensitivity of 88.6% (95% confidence interval [CI] 85.3-91.3) and specificity of 84.6% (95% CI 81.1-87.7) for PCOM diagnosis as well as an area under the receiver-operator characteristic curve of 93.6% (95% CI 92.2-95.1). In women aged 25-35 years, the sensitivity and specificity for the cutoff were 88.5% and 80.3%, respectively, versus 77.8% and 90.1%, respectively, in women aged 36-45 years. The results were consistent across PCOS phenotypes A-D. CONCLUSION(S): The Elecsys AMH Plus immunoassay, with a cutoff of 3.2 ng/mL (23 pmol/L), is a robust method for identifying PCOM to aid in PCOS diagnosis.

BACKGROUND: Cardiovascular disease (CVD) is the leading cause of death in women worldwide. The cardiovascular risk profile deteriorates after women enter menopause. By definition, women diagnosed with premature ovarian insufficiency (POI) experience menopause before 40 years of age, which may render these women even more susceptible to develop CVD later in life. However, prospective long-term follow up data of well phenotyped women with POI are scarce. In the current study we compare the CVD profile and risk of middle aged women previously diagnosed with POI, to a population based reference group matched for age and BMI. METHODS AND FINDINGS: We compared 123 women (age 49.0 (± 4.3) years) and diagnosed with POI 8.1 (IQR: 6.8-9.6) years earlier, with 123 population controls (age 49.4 (± 3.9) years). All women underwent an extensive standardized cardiovascular screening. We assessed CVD risk factors including waist circumference, BMI, blood pressure, lipid profile, pulse wave velocity (PWV), and the prevalence of diabetes mellitus, metabolic syndrome (MetS) and carotid intima media thickness (cIMT), in both women with POI and controls. We calculated the 10-year CVD Framingham Risk Score (FRS) and the American Heart Association's suggested cardiovascular health score (CHS). Waist circumference (90.0 (IQR: 83.0-98.0) versus 80.7 (IQR: 75.1-86.8), p < 0.01), waist-to-hip ratio (0.90 (IQR: 0.85-0.93) versus 0.79 (IQR: 0.75-0.83), p < 0.01), systolic blood pressure (124 (IQR 112-135) versus 120 (IQR109-131), p < 0.04) and diastolic blood pressure (81 (IQR: 76-89) versus 78 (IQR: 71-86), p < 0.01), prevalence of hypertension (45 (37%) versus 21 (17%), p < 0.01) and MetS (19 (16%) versus 4 (3%), p < 0.01) were all significantly increased in women with POI compared to healthy controls. Other risk factors, however, such as lipids, glucose levels and prevalence of diabetes were similar comparing women with POI versus controls. The arterial stiffness assessed by PWV was also similar in both populations (8.1 (IQR: 7.1-9.4) versus 7.9 (IQR: 7.1-8.4), p = 0.21). In addition, cIMT was lower in women with POI compared to controls (550 µm (500-615) versus 684 µm (618-737), p < 0.01). The calculated 10-year CVD risk was 5.9% (IQR: 3.7-10.6) versus 6.0% (IQR: 3.9-9.0) (p = 0.31) and current CHS was 6.1 (1.9) versus 6.5 (1.6) (p = 0.07), respectively in POI versus controls. CONCLUSIONS: Middle age women with POI presented with more unfavorable cardiovascular risk factors (increased waist circumference and a higher prevalence of hypertension and MetS) compared to age and BMI matched population controls. In contrast, the current study reveals a lower cIMT and similar 10-year cardiovascular disease risk and cardiovascular health score. In summary, neither signs of premature atherosclerosis nor a worse cardiovascular disease risk or health score were observed among middle age women with POI compared to population controls. Longer-term follow-up studies of women of more advanced age are warranted to establish whether women with POI are truly at increased risk of developing CVD events later in life.

BACKGROUND: Preeclampsia, coronary artery calcification (CAC), and atherosclerotic plaque are risk factors for the development of cardiovascular disease. We determined at what age CAC becomes apparent on coronary computed tomography after preeclampsia and to what extent modifiable cardiovascular risk factors were associated. METHODS: We measured cardiovascular risk factors, CAC by coronary computed tomography, and coronary plaque by coronary computed tomography angiography in 258 previously preeclamptic women aged 40-63. Results were compared to 644 age- and ethnicity-equivalent women from the Framingham Heart Study with previous normotensive pregnancies. RESULTS: Any CAC was more prevalent after preeclampsia than after a normotensive pregnancy (20% versus 13%). However, this difference was greatest and statistically significant only in women ages 45 to 50 (23% versus 10%). The degree of CAC advanced 4× faster between the ages of 40 to 45 and ages 45 to 50 in women with a history of preeclampsia (odds ratio, 4.3 [95% CI, 1.5-12.2] versus odds ratio, 1.2 [95% CI, 0.6-2.3]). Women with a preeclampsia history maintained greater advancement of CAC with age into their early 60s, although this difference declined after the perimenopausal years. Women with a previous normotensive pregnancy were 4.9 years (95% CI, 1.8-8.0) older when they had similar CAC scores as previously preeclamptic women. These observations were not explained by the greater prevalence of cardiovascular disease risk factors, and the higher Framingham Risk Scores also observed in women with a history of preeclampsia. CONCLUSIONS: Previously preeclamptic women have more modifiable cardiovascular risk factors and develop CAC ≈5 years earlier from the age of 45 years onwards compared to women with normotensive pregnancies. Therefore, women who experienced preeclampsia might benefit from regular cardiovascular screening and intervention before this age.

CONTEXT: As many as 75% of patients with polycystic ovary syndrome (PCOS) are estimated to be unidentified in clinical practice. OBJECTIVE: Utilizing polygenic risk prediction, we aim to identify the phenome-wide comorbidity patterns characteristic of PCOS to improve accurate diagnosis and preventive treatment. DESIGN, PATIENTS, AND METHODS: Leveraging the electronic health records (EHRs) of 124â 852 individuals, we developed a PCOS risk prediction algorithm by combining polygenic risk scores (PRS) with PCOS component phenotypes into a polygenic and phenotypic risk score (PPRS). We evaluated its predictive capability across different ancestries and perform a PRS-based phenome-wide association study (PheWAS) to assess the phenomic expression of the heightened risk of PCOS. RESULTS: The integrated polygenic prediction improved the average performance (pseudo-R2) for PCOS detection by 0.228 (61.5-fold), 0.224 (58.8-fold), 0.211 (57.0-fold) over the null model across European, African, and multi-ancestry participants respectively. The subsequent PRS-powered PheWAS identified a high level of shared biology between PCOS and a range of metabolic and endocrine outcomes, especially with obesity and diabetes: "morbid obesity", "type 2 diabetes", "hypercholesterolemia", "disorders of lipid metabolism", "hypertension", and "sleep apnea" reaching phenome-wide significance. CONCLUSIONS: Our study has expanded the methodological utility of PRS in patient stratification and risk prediction, especially in a multifactorial condition like PCOS, across different genetic origins. By utilizing the individual genome-phenome data available from the EHR, our approach also demonstrates that polygenic prediction by PRS can provide valuable opportunities to discover the pleiotropic phenomic network associated with PCOS pathogenesis.

Context: Women with polycystic ovary syndrome (PCOS) are at increased risk for obstetric and perinatal complications. At present, it is unknown how characteristics of PCOS relate to the likelihood of these complications. Objective: To evaluate which preconception features are associated with obstetric and perinatal disease among infertile women with PCOS. Design: Data from two prospective cohort studies completed from January 2004 until January 2014 were linked to Dutch Perinatal national registry outcomes. Setting: Two Dutch university medical centers. Participants: 2768 women diagnosed with PCOS were included. Participants underwent an extensive standardized preconception screening. Exclusion criteria included: age <18 years or >45 years, language barrier, or failure to meet PCOS criteria. Interventions: None. Main Outcome Measures: Outcome measures were obtained from the Dutch Perinatal national registry and included: preeclampsia, preterm delivery, small for gestational age (SGA), low Apgar score, and any adverse outcome. Results: 1715 (62% of participants) women with PCOS were identified as undergoing a pregnancy with live birth after screening. In fully adjusted models, prepregnancy free androgen index was associated with subsequent preeclampsia [OR (95% CI), 1.1 (1.0 to 1.1)]. Fasting glucose [1.4 (1.2 to 1.7)] and testosterone [1.5 (1.2 to 1.7)] predicted preterm delivery. Fasting insulin [1.003 (1.001 to 1.005)], and testosterone [1.2 (1.1 to 1.4)] predicted any adverse outcome. SGA was only predicted by features nonspecific to PCOS. Conclusions: Primary disease characteristics of PCOS, chiefly hyperandrogenism and impaired glucose tolerance, predict suboptimal obstetric and neonatal outcomes. Increased surveillance during pregnancy should focus on women with PCOS and these features to help mitigate disease risk.

Context: Polycystic ovary syndrome (PCOS) is closely linked to hyperandrogenism (HA). In PCOS, HA has been associated with metabolic disturbances that increase the risk for cardiovascular disease (CVD). Objective: To assess the association of high serum androgen levels, as a postmenopausal remnant of PCOS, with the prevalence of atherosclerosis and incidence of CVD in postmenopausal women. Design: The Rotterdam Study, a prospective population-based cohort study. Median follow-up was 11.36 years. Setting: General community. Participants: A total of 2578 women aged >55 years. Exclusion criteria were missing informed consent or follow-up data, perimenopausal status, and menopause by surgical intervention or at an unnatural age (age <40 or >62). Intervention: None. Main Outcomes and Measures: Linear, logistic, and Cox regression models assessed the association of top quartiles (P75) of serum testosterone, free androgen index (FAI), dehydroepiandrosterone, and androstenedione and sex hormone-binding globulin with coronary artery calcium, carotid intima-media thickness (IMT), pulse wave velocity, peripheral artery disease, and incidence of coronary heart disease (CHD), stroke, and CVD. Results: Mean age (standard deviation) was 70.19 (8.71) years, and average time since menopause was 19.85 (9.94) years. Highest quartile FAI was associated with higher pulse wave velocity (ß [95% confidence interval (CI)], 0.009 [0.000 to 0.018]). Highest quartile dehydroepiandrosterone [ß (95% CI), -0.008 (-0.015 to -0.001)] and androstenedione [ß (95% CI), -0.010 (-0.017 to -0.003)] levels were associated with a lower IMT. We found no association between high androgen levels and incident stroke, CHD, or CVD. Conclusion: Postmenopausal high androgen levels were not associated with an elevated risk for CVD. Cardiovascular health in women with PCOS might be better than was anticipated.

It remains unclear whether endogenous sex hormones (ESH) are associated with risk of type 2 diabetes (T2D) in women. Data of 3,117 postmenopausal women participants of the Rotterdam Study were analyzed to examine whether ESH and sex hormone-binding globulin (SHBG) were associated with the risk of incident T2D. Additionally, we performed a systematic review and meta-analysis of studies assessing the prospective association of ESH and SHBG with T2D in women. During a median follow-up of 11.1 years, we identified 384 incident cases of T2D in the Rotterdam Study. No association was observed between total testosterone (TT) or bioavailable testosterone (BT) with T2D. SHBG was inversely associated with the risk of T2D, whereas total estradiol (TE) was associated with increased risk of T2D. Similarly, in the meta-analysis of 13 population-based prospective studies involving more than 1,912 incident T2D cases, low levels of SHBG and high levels of TE were associated with increased risk of T2D, whereas no associations were found for other hormones. The association of SHBG with T2D did not change by menopause status, whereas the associations of ESH and T2D were based only in postmenopausal women. SHBG and TE are independent risk factors for the development of T2D in women.

CONTEXT: The concept of cardiovascular health was recently introduced. Sex steroids and sex hormone-binding globulin (SHBG) influence different health domains, but no studies assessed their role in cardiovascular health. OBJECTIVE: To assess the association between estradiol (E2), testosterone (T), SHBG, and free androgen index (FAI) with cardiovascular health. DESIGN, SETTING, AND PARTICIPANTS: Analyses included 1647 men (68.6 y) and 1564 naturally postmenopausal women (69.6 y) with available data on sex steroids and cardiovascular health from the population-based Rotterdam Study. EXPOSURES: E2, T, SHBG, and FAI. OUTCOME: To define cardiovascular health, 7 metrics including 3 health factors (total cholesterol, fasting glucose, and blood pressure) and 4 health behaviors (physical activity, smoking, body mass index, and diet) were adopted. Three category levels of each metric were added up to a total score ranged 0-14. Logistic regression was performed to explore the association between E2, T, SHBG, and FAI and optimal cardiovascular health (OCH) (score of 11-14). RESULTS: OCH was reached by 153 men (9.3%) and 162 women (10.4%). The prevalence of OCH was higher in the lowest tertile of E2 (38.9%), and of T (43.8%), and the highest tertile of SHBG (48.1%) in women, and the highest tertile of T (43.1%) and SHBG (47.1%) in men. After adjustment for confounders, OCH was associated with lower T (odds ratio and 95% confidence interval, 0.69 [0.48-1.00]) and lower FAI (0.43 [0.32-0.57]) and higher levels of SHBG (4.55 [2.99-6.94]) among women and with higher levels of SHBG (2.56 [1.45-4.49]) in men. CONCLUSIONS: OCH was associated with sex steroids and with SHBG in both men and women. The complexity and temporality of the interrelation between sex steroids, SHBG, and cardiovascular health requires further investigation.

CONTEXT: A young age at menopause has been associated with increased cardiovascular disease (CVD) risk. OBJECTIVE: To compare the cardiovascular risk profile between women with premature ovarian insufficiency (POI) and premenopausal controls of comparable age. DESIGN: Cross-sectional case control study. SETTING: Two university medical centers. PARTICIPANTS: Women above 45 years of age who were previously diagnosed with POI (n = 83) and premenopausal population controls of comparable age (n = 266). MAIN OUTCOME MEASURES: Blood pressure, body mass index, waist circumference, electrocardiogram, bilateral carotid intima media thickness, estradiol, T, androstenedione, dehydroepiandrosterone sulfate, SHBG, insulin, glucose, lipids, TSH, free T4, N-terminal pro-B-type natriuretic peptide, C-reactive protein, uric acid, creatinine, and homocysteine were measured. Potential associations between POI status and subclinical atherosclerosis were assessed. RESULTS: Women with POI exhibited an increased waist circumference (ß = 5.7; 95% confidence interval [CI], 1.6, 9.9), C-reactive protein (ß = 0.75; 95% CI, 0.43, 1.08), free T4 levels (ß = 1.5; 95% CI, 0.6, 2.4), and lower N-terminal pro-B-type natriuretic peptide (ß = -0.35; 95% CI, -0.62, -0.08), estradiol (ß = -1.98; 95% CI, -2.48, -1.48), T (ß = -0.21; 95% CI, -0.37, -0.06), and androstenedione (ß = -0.54; 95% CI, -0.71, -0.38) concentrations compared to controls, after adjusting for confounders. After adjustment, a trend toward increased hypertension (odds ratio = 2.1; 95% CI, 0.99; 4.56) and decreased kidney function was observed in women with POI (creatinine ß = 3.5; 95% CI, -0.05, 7.1; glomerular filtration rate ß = -3.5; 95% CI, -7.5, 0.46). Women with POI exhibited a lower mean carotid intima media thickness (ß = -0.17; 95% CI, -0.21, -0.13) and decreased odds of plaque presence compared to controls (odds ratio = 0.08; 95% CI, 0.03; 0.26). CONCLUSIONS: Women with POI exhibited an unfavorable cardiovascular risk profile, including higher abdominal fat, elevated chronic inflammatory factors, and a trend toward increased hypertension and impaired kidney function compared to controls. However, we observed no signs of increased subclinical atherosclerosis in women with POI. Additional studies are required to identify specific determinants of long-term CVD risk in women with POI.

Middle-aged and elderly women constitute a large and growing proportion of the population. The peri and postmenopausal period constitutes a challenging transition time for women's health, and menopausal health is a crucial aspect in healthy and successful aging. Currently, no framework for the concept of healthy menopause exists, despite its recognized importance. Therefore, we aimed to: (i) characterize healthy menopause; (ii) identify aspects that contribute to it; and (iii) explore potential approaches to measure it. We propose healthy menopause as a dynamic state, following the permanent loss of ovarian function, which is characterized by self-perceived satisfactory physical, psychological and social functioning, incorporating disease and disability, allowing the attainment of a woman's desired ability to adapt and capacity to self-manage. The concept of healthy menopause applies to all women from the moment they enter the menopausal transition, up until they reach early and late postmenopause and includes women with spontaneous, iatrogenic, and premature menopause. This conceptualization can be considered as a further step in the maintenance and improvement of health in menopausal women from different perspectives, foremost the woman's own perspective, followed by the clinical, public health, and societal perspectives, and can be seen as a further step in delineating lines for future research. Furthermore, it could facilitate the improvement of adequate preventive and treatment strategies, guide scientific efforts, and aid education and communication to health care practitioners and the general public, allowing women the achievement of their potential and the fulfillment of their fundamental role in society.

Polycystic ovary syndrome (PCOS) is the most common reproductive disorder in women, yet there is little consensus regarding its aetiology. Here we perform a genome-wide association study of PCOS in up to 5,184 self-reported cases of White European ancestry and 82,759 controls, with follow-up in a further â¼2,000 clinically validated cases and â¼100,000 controls. We identify six signals for PCOS at genome-wide statistical significance (P<5 × 10(-8)), in/near genes ERBB4/HER4, YAP1, THADA, FSHB, RAD50 and KRR1. Variants in/near three of the four epidermal growth factor receptor genes (ERBB2/HER2, ERBB3/HER3 and ERBB4/HER4) are associated with PCOS at or near genome-wide significance. Mendelian randomization analyses indicate causal roles in PCOS aetiology for higher BMI (P=2.5 × 10(-9)), higher insulin resistance (P=6 × 10(-4)) and lower serum sex hormone binding globulin concentrations (P=5 × 10(-4)). Furthermore, genetic susceptibility to later menopause is associated with higher PCOS risk (P=1.6 × 10(-8)) and PCOS-susceptibility alleles are associated with higher serum anti-Müllerian hormone concentrations in girls (P=8.9 × 10(-5)). This large-scale study implicates an aetiological role of the epidermal growth factor receptors, infers causal mechanisms relevant to clinical management and prevention, and suggests balancing selection mechanisms involved in PCOS risk.
