Abstract
The incidence and prevalence of youth-onset type 2 diabetes mellitus (T2DM) are increasing. The rise in frequency and severity of childhood obesity, inclination to sedentary lifestyle, and epigenetic risks related to prenatal hyperglycemia exposure are important drivers of the youth-onset T2DM epidemic and might as well be responsible for the early onset of diabetes complications. Indeed, youth-onset T2DM has a more extreme metabolic phenotype than adult-onset T2DM, with greater insulin resistance and more rapid deterioration of beta cell function. Therefore, intermediate complications such as microalbuminuria develop in late childhood or early adulthood, while end-stage complications develop in mid-life. Due to the lack of efficacy and safety data, several drugs available for the treatment of adults with T2DM have not been approved in youth, reducing the pharmacological treatment options. In this mini review, we will try to address the present challenges and pitfalls related to youth-onset T2DM and summarize the available interventions to mitigate the risk of microvascular and macrovascular complications.

Irregular Cycles, Ovulatory Disorders, and Cardiometabolic Conditions in a US-Based Digital Cohort. JAMA Netw Open 2024; 7:e249657. [PMID: 38700861 PMCID: PMC11069087 DOI: 10.1001/jamanetworkopen.2024.9657] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/31/2023] [Accepted: 03/05/2024] [Indexed: 05/06/2024] Open
Abstract
Importance Polycystic ovary syndrome (PCOS), characterized by irregular menstrual cycles and hyperandrogenism, is a common ovulatory disorder. Having an irregular cycle is a potential marker for cardiometabolic conditions, but data are limited on whether the associations differ by PCOS status or potential interventions. Objective To evaluate the association of PCOS, time to regularity since menarche (adolescence), and irregular cycles (adulthood) with cardiometabolic conditions. Design, Setting, and Participants This cross-sectional study used a large, US-based digital cohort of users of the Apple Research application on their iPhone. Eligibility criteria were having ever menstruated, living in the US, being at age of consent of at least 18 years (or 19 years in Alabama and Nebraska or 21 years in Puerto Rico), and being able to communicate in English. Participants were enrolled between November 14, 2019, and December 13, 2022, and completed relevant surveys. Exposures Self-reported PCOS diagnosis, prolonged time to regularity (not spontaneously establishing regularity within 5 years of menarche), and irregular cycles. Main Outcomes and Measures The primary outcome was self-reported cardiometabolic conditions, including obesity, prediabetes, type 1 and 2 diabetes, high cholesterol, hypertension, metabolic syndrome, arrhythmia, congestive heart failure, coronary artery disease, heart attack, heart valve disease, stroke, transient ischemic attack (TIA), deep vein thrombosis, and pulmonary embolism measured using descriptive statistics and logistic regression to estimate prevalence odds ratios (PORs) and 95% CIs. Effect modification by lifestyle factors was also estimated. Results The study sample (N = 60 789) had a mean (SD) age of 34.5 (11.1) years, with 12.3% having PCOS and 26.3% having prolonged time to regularity. Among a subset of 25 399 participants who completed the hormonal symptoms survey, 25.6% reported irregular cycles. In covariate-adjusted logistic regression models, PCOS was associated with a higher prevalence of all metabolic and several cardiovascular conditions, eg, arrhythmia (POR, 1.37; 95% CI, 1.20-1.55), coronary artery disease (POR, 2.92; 95% CI, 1.95-4.29), heart attack (POR, 1.79; 95% CI, 1.23-2.54), and stroke (POR, 1.66; 95% CI, 1.21-2.24). Among participants without PCOS, prolonged time to regularity was associated with type 2 diabetes (POR, 1.24; 95% CI, 1.05-1.46), hypertension (POR, 1.09; 95% CI, 1.01-1.19), arrhythmia (POR, 1.20; 95% CI, 1.06-1.35), and TIA (POR, 1.33; 95% CI, 1.01-1.73), and having irregular cycles was associated with type 2 diabetes (POR, 1.36; 95% CI, 1.08-1.69), high cholesterol (POR, 1.17; 95% CI, 1.05-1.30), arrhythmia (POR, 1.21; 95% CI, 1.02-1.43), and TIA (POR, 1.56; 95% CI, 1.06-2.26). Some of these associations were modified by high vs low body mass index or low vs high physical activity. Conclusions and Relevance These findings suggest that PCOS and irregular cycles may be independent markers for cardiometabolic conditions. Early screening and intervention among individuals with irregular menstrual cycles may be beneficial.

Abstract
Background Polycystic ovary syndrome (PCOS) is the most common metabolic-endocrine disorder impacting the health and quality of life of women over the lifespan. Evidence-based data on the scope of adverse health outcomes in those affected by PCOS is critical to improve healthcare and quality of life in this population. The aim of this study was to determine the prevalence of adverse health outcomes in those with PCOS compared to age-matched controls. Methods We conducted a retrospective observational case-control study in those diagnosed with PCOS and age-matched controls using the Alberta Health Services Health Analytics database and the International Classification of Diseases, for the period from 2002-2018 in Alberta, Canada. Results The cohort consisted of n = 16,531 exposed PCOS cases and n = 49,335 age-matched un-exposed controls. The prevalences of hypertension, renal disease, gastrointestinal disease, eating disorders, mental illness, depression-anxiety, rheumatoid arthritis, respiratory infections, and all malignancies were 20%-40% (P < 0.0001) higher in those with PCOS, compared to controls. The prevalence of obesity, dyslipidemia, nonalcoholic fatty liver disease, and type 2 diabetes was 2-3 fold higher in those with PCOS (P < 0.001). Cardiovascular, cerebrovascular, and peripheral vascular disease were 30%-50% higher, and they occurred 3-4 years earlier in those with PCOS (P < 0.0001); a 2-fold higher prevalence of dementia occurred in those with PCOS, compared to controls. Conclusion These findings provide evidence that PCOS is associated with a higher prevalence of morbidities over the lifespan, and the potential scope of the healthcare burden in women affected by PCOS.

Abstract
Cesarean section in a mother with a sextuplet pregnancy is challenging for an anesthesiologist. Several perioperative complications are likely because of the overdistended uterus and associated changes in the mother. We are reporting the case of a woman with a sextuplet pregnancy who came for an emergency cesarean. She also had a background history of polycystic ovarian syndrome (PCOS) and ovulation induction for conception. Early pregnancy was complicated by ovarian hyperstimulation syndrome. She required cervical cerclage in early pregnancy. The emergency cesarean was done as she went into preterm labor and six premature babies were delivered at 29 weeks of gestation. Cesarean was done under spinal anesthesia. Preeclampsia and postpartum hemorrhage complicated the perioperative period.

Abstract
OBJECTIVE To investigate associations between maternal testosterone status and offspring birth anthropometrics. DESIGN Population-based prospective cohort study. SETTING University Hospital. POPULATION 1486 mother-child dyads from Odense Child Cohort. METHODS Maternal blood samples were collected at gestational weeks 27-30 and free testosterone (FT) levels were calculated using the Vermeulen equation from total testosterone (TT) analysed by mass spectrometry and sex hormone binding globulin. Associations between FT or TT levels and birth anthropometrics were analysed with multiple linear regression models according to offspring sex with adjustment for maternal age, parity, smoking and educational level. Analyses were repeated with polycystic ovary syndrome as exposure for offspring birth anthropometrics. MAIN OUTCOME MEASURES Offspring birth weight (BW), birth length, abdominal and head circumferences. RESULTS Maternal mean (SD) age was 30.2 (4.5) years and pre-pregnancy body mass index was 23.5 (5.3) kg/m2 . In boys (n = 787), higher FT was associated with lower birth weight (adjusted doubling constant = -65.53, P = 0.010), shorter birth length (adjusted doubling constant = -0.43, P < 0.001), and lower abdominal circumference (adjusted doubling constant = -0.39, P < 0.001); Higher TT was associated with lower abdominal circumference (adjusted doubling constant = -0.25, P = 0.028). In girls, no associations were found between maternal FT or TT and offspring anthropometrics. CONCLUSIONS Higher maternal free testosterone exposure was linked to reduced birth weight, length and abdominal circumference in boys, whereas girls were not susceptible to maternal testosterone exposure.

Abstract
OBJECTIVE We aimed to compare pregnancy and neonatal outcomes in the phenotypic subtypes of patients with polycystic ovary syndrome (PCOS). METHODS This prospective cohort included the patients with PCOS (n = 121) diagnosed according to the presence of androgen excess, ovulatory dysfunction, and/or polycystic ovary morphology and healthy controls (n = 125). We stratified PCOS as phenotype A (n = 45), phenotype B (n = 8), phenotype C (n = 32) and phenotype D (n = 35) and followed throughout pregnancy, comparing their outcomes. RESULTS The study population had a mean age of 28.7 ± 4.9 years and a mean BMI of 31.6 kg/m2 with no difference between the groups. Primary cesarean deliveries were significantly more common in PCOS patients (23.3%) than in the control group (17.6%, P = 0.021). The phenotype A group had significantly higher rates of gestational diabetes mellitus (GDM) (42.2%, P < 0.001) and fetal macrosomia (14.6%, P = 0.002) compared with the control group (4.8% and 0.8%m respectively). We detected a significantly lower rate of normal risk score on the double screening test in the PCOS group (59.0%) than in the control group (75.4%) and in the other groups (P = 0.001). CONCLUSION The rates of GDM, fetal macrosomia, and cesarean section were higher in the PCOS group, depending on the phenotype. We observed changes in risk calculation according to phenotypic types at aneuploidy screening.

Abstract
Gestational diabetes mellitus (GDM) is the most common complication of pregnancy that arises in the 2nd and 3rd trimesters, leading to significant complications for the mother and her neonates, such as an increased rate of pregnancy-induced hypertension and miscarriages, while neonates may have a large birth weight, hypoglycemia, or macrosomnia. Numerous risk factors can lead to GDM; however, a significant one is polycystic ovarian syndrome (PCOS). PCOS is the most common endocrine pathology beginning before puberty, and due to significant hormonal changes, it is not diagnosed until after puberty. PCOS requires at least three of the following symptoms: hyperandrogenism, menstrual irregularities, or polycystic ovary morphology. While it is agreed that women with PCOS are at a significantly increased risk of GDM, no publication to our knowledge has evaluated the full relationship of GDM in the setting of PCOS. This paper aimed to assess this relationship and determine how it may differ for pregnant women with only GDM by determining the prevalence of GDM, the variations within phenotypes, the influence of fertilization methods, specific risk factors, maternal outcomes, and neonatal outcomes. The prevalence of GDM was significantly increased in women with PCOS compared to healthy controls, and some studies have found that phenotype A may be more likely to lead to GDM. Risk factors were similar to pregnant women with only GDM, but with GDM and PCOS specifically, preconception low sex hormone-binding globulin, increased BMI > 25 kg/m2, and preconception impaired glucose tolerance were specific. While maternal outcomes were similar to pregnant women with only GDM, women with GDM and PCOS were even more likely to develop pregnancy-induced hypertension and early miscarriage. Neonates from mothers with GDM and PCOS were more likely to have low birth weights compared to mothers with just GDM who had high birth weights. The evaluation of the relationship between GDM and PCOS allows for illumination of the need to evaluate influences that currently lack research, such as phenotype variation and influences of fertilization method. This also promotes the need to develop predictive algorithms based on risk factors to prevent these adverse outcomes for mothers and neonates.

Abstract
OBJECTIVE To systematically assess the efficacy of ω-3 polyunsaturated fatty acids (PUFAs) when treating polycystic ovary syndrome (PCOS). METHODS This meta-analysis follows Preferred Reporting Items for Systematic Reviews and Meta-Analyses criteria. We searched PubMed, EMBASE, ScienceDirect, Cochrane Library, China journal full-text database, VIP full-text Database, Wanfang Database, and Chinese Biomedical Literature Data for clinical trials on ω-3 PUFAs' efficacy in treating PCOS. Two independent reviewers examined and analyzed studies, resolving inconsistencies through discussion. RevMan5.3 software performed heterogeneity-based fixed and random-effects meta-analysis. We assessed bias using the Cochrane bias risk assessment tool. RESULTS Our meta-analysis included 7 clinical control studies comprising 574 samples to evaluate the impact of ω-3 PUFAs on various metabolic markers in PCOS patients. We observed a significant reduction in total cholesterol (TC) and triglyceride (TG) levels (P < .05), along with a decrease in insulin resistance as measured by the Homeostatic Model Assessment for Insulin Resistance (HOMA-IR) (P < .05). Testosterone (T) levels were also lowered in the study group post-treatment (P < .05). However, no notable effects were found on body mass index (BMI), fasting blood sugar (FBS), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), and Ferriman-Gallwey (mFG) scores (P > .05). Publication bias was not detected, enhancing the robustness of our results. Our study suggests that ω-3 PUFAs could be beneficial in managing specific metabolic markers in PCOS, although the results showed marked heterogeneity. CONCLUSION In PCOS patients, PUFAs can enhance reproductive endocrine, glucose, and lipid levels. However, additional research and extended follow-up are required to confirm this.

Abstract
Objective Sex steroid hormones may play a role in insulin resistance and glucose dysregulation. However, evidence regarding associations between early-pregnancy sex steroid hormones and hyperglycemia during pregnancy is limited. The primary objective of this study was to assess the relationships between first trimester sex steroid hormones and the subsequent development of hyperglycemia during pregnancy; with secondary evaluation of sex steroid hormones levels in mid-late pregnancy, concurrent with and subsequent to diagnosis of gestational diabetes. Methods Retrospective analysis of a prospective pregnancy cohort study was conducted. Medically low-risk participants with no known major endocrine disorders were recruited in the first trimester of pregnancy (n=319). Sex steroid hormones in each trimester, including total testosterone, free testosterone, estrone, estradiol, and estriol, were assessed using high-performance liquid chromatography and tandem mass spectrometry. Glucose levels of the 1-hour oral glucose tolerance test and gestational diabetes diagnosis were abstracted from medical records. Multivariable linear regression models were fitted to assess the associations of individual first trimester sex steroids and glucose levels. Results In adjusted models, first trimester total testosterone (β=5.24, 95% CI: 0.01, 10.46, p=0.05) and free testosterone (β=5.98, 95% CI: 0.97, 10.98, p=0.02) were positively associated with subsequent glucose concentrations and gestational diabetes diagnosis (total testosterone: OR=3.63, 95% CI: 1.50, 8.78; free testosterone: OR=3.69; 95% CI: 1.56, 8.73). First trimester estrone was also positively associated with gestational diabetes (OR=3.66, 95% CI: 1.56, 8.55). In mid-late pregnancy, pregnant people with gestational diabetes had lower total testosterone levels (β=-0.19, 95% CI: -0.36, -0.02) after adjustment for first trimester total testosterone. Conclusion Early-pregnancy sex steroid hormones, including total testosterone, free testosterone, and estrone, were positively associated with glucose levels and gestational diabetes in mid-late pregnancy. These hormones may serve as early predictors of gestational diabetes in combination with other risk factors.

Objectives: To apply a case definition to a Northern Alberta-based primary care practice population and to assess the sex-specific characteristics of young-onset metabolic syndrome (MetS). Design: We carried out a cross-sectional study to identify and estimate the prevalence of MetS using electronic medical record (EMR) data and perform descriptive comparative analyses of demographic and clinical characteristics between males and females. Setting: Northern Alberta Primary Care Research Network (NAPCReN) consists of EMR patient data from 77 physicians among 18 clinics. Participants: Patients with one or more clinic visit between 2015 and 2018, between 18 and 40 years old, residing in Northern Alberta. Main Outcome Measures: Comparison of prevalence in MetS between sexes as well as sex-specific distribution of MetS characteristics [body mass index (BMI), fasting blood glucose, glycated hemoglobin, triglycerides, and high-density lipoprotein cholesterol (HDL-C), presence of hypertension, and presence of diabetes]. Results: Of 15,766 patients, 4.4% (n = 700) had young-onset MetS based on recorded data, prevalence was nearly twice as high in males (6.1%, n = 354) compared with females (3.5%, n = 346). The most prevalent risk factor for MetS consisted of having an elevated BMI for both females (90.9%) and males (91.5%). In the presence of MetS, more females had lower HDL-C [68.2% females (F) vs. 52.5% males (M)], and higher prevalence of diabetes (21.4% F vs. 9.0% M), whereas more males had hypertriglyceridemia (60.4% F vs. 79.7% M) and hypertension (12.4% F vs. 15.8% M). Females also had consistently higher percentages of absent laboratory data compared with males when identified as having MetS and BMI ≥25 kg/m2. Conclusions: Males have nearly twice the prevalence of young-onset MetS compared with females, with notable sex-specific differences in the manifestation of MetS, although we suspect that this is partially due to underreporting where the absence of anthropomorphic and laboratory investigations point to a lack of testing. Sex-specific screening for MetS, especially among young females of childbearing years, is important for downstream prevention.

J Clin Endocrinol Metab 2022; 108:114-123. [PMID: 36125321 DOI: 10.1210/clinem/dgac538] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/30/2022] [Revised: 09/10/2022] [Indexed: 02/03/2023]
Abstract
BACKGROUND A limited number of studies have investigated the impact of idiopathic hirsutism (IH) on cardiometabolic parameters with contradictory and inconclusive results. This study aimed to explore the effect of IH on metabolic outcomes. METHOD In this population-based prospective study, 334 women with IH and 1226 women as healthy controls were selected from Tehran Lipid and Glucose Study. The generalized estimation equations method was applied to investigate the secular longitudinal trends of metabolic indices, including fasting blood sugar (FBS), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL), non-HDL, triglyceride (TG), systolic blood pressure (SBP), diastolic blood pressure (DBP), and waist circumference (WC) in both groups. Unadjusted and adjusted Cox regression models were applied to assess the hazard ratios (HR) and 95% CIs for the association between IH and metabolic disorders. Potential confounding factors such as age, body mass index, smoking, physical activity, history of hypertension (HTN), and family history of diabetes were included in the adjusted model. RESULTS This study showed that compared with healthy controls, women with IH had lower SHBG and higher total testosterone (median [interquartile ratio; IQR]: 0.37 [0.16-0.70] vs 0.33 [0.14-0.58]; P = 0.01), free androgen index (median [IQR]: 0.85 [0.38-1.54] vs 0.54 [0.26-0.97]; P = 0.001), androstenedione (median [IQR]: 1.60 [1.00-2.25] vs 1.10 [0.90-1.70]; P = 0.001), and dehydroepiandrosterone sulfate (median [IQR]: 168.5 [91.1-227.8] vs 125.2 [66.3-181]; P = 0.001). Over time, mean changes of FBS, HDL-C, LDL-C, non-HDL-C, TG, SBP, DBP, and WC were not significantly different in women with IH, compared with healthy controls. According to the unadjusted Cox regression model, except for type 2 diabetes mellitus (T2DM) (HR [95% CI]: 1.45 [1.00-2.11]) P = 0.05; there was no statistically significant difference in hazard of metabolic disorders (ie, HTN, pre-HTN, pre-T2DM, and metabolic syndrome) in IH, compared with healthy controls. Besides, the adjusted Cox regression model showed no significant differences in the hazard of these outcomes. CONCLUSION This study showed no significant difference in overtime mean changes of metabolic risk factors and cardiometabolic outcomes in women with IH, compared with the healthy control group, except marginally significant difference on T2DM, which disappeared after further adjustment for potential confounders. Accordingly, routine screening of women for these metabolic outcomes should not recommend.

Abstract
OBJECTIVE To evaluate and compare pregnancy outcomes between letrozole ovulation induction, natural, and programmed frozen-thawed embryo transfer (FET) cycles in a population based in the United States. DESIGN Retrospective cohort study. SETTING Single university-affiliated infertility practice. PATIENT(S) A total of 3,148 FET cycles consisting of patients aged ≤45 years transferring blastocysts that were created from autologous oocytes between January 2015 and July 2021. INTERVENTION(S) None. MAIN OUTCOME MEASURE(S) The primary outcome was the ongoing pregnancy rate (OPR) or live birth rate (LBR). The secondary outcomes included clinical pregnancy and clinical loss rates (CLRs). RESULT(S) The OPR/LBR was higher among letrozole FETs than among programmed FETs (adjusted risk ratio [aRR] 1.11, 95% confidence interval [CI] 1.02-1.21) but comparable to natural FETs (aRR 1.05, 95% CI 0.96-1.14). The OPR/LBR was comparable between natural and programmed FETs (aRR 1.06, 95% CI 0.99-1.13). The CLR was lower in the natural FET group than in the programmed FET group (aRR 0.62, 95% CI 0.46-0.84). There were no differences in CLRs between letrozole and programmed FETs and between letrozole and natural FETs. Among ovulatory women, the OPR/LBR among letrozole FETs was higher than that among programmed FETs (aRR 1.16, 95% CI 1.05-1.28). The CLR among ovulatory women was significantly lower in both letrozole FETs (aRR 0.44, 95% CI 0.22-0.87) and natural FETs (aRR 0.59, 95% CI 0.43-0.80) than in programmed FETs. Among anovulatory women, the OPR/LBR in the letrozole FET group was similar to that in the programmed FET group (aRR 0.95, 95% CI 0.79-1.13). CONCLUSION(S) Letrozole and natural FET clinical outcomes were improved compared with programmed FET outcomes.

Abstract
OBJECTIVES The results of studies regarding the association between polycystic ovary syndrome (PCOS) and gestational diabetes mellitus (GDM) are controversial. DESIGN This meta-analysis was conducted to evaluate the relationship between PCOS and GDM. METHODS English language articles published before July 2021 were included by searching in databases: PubMed, EMBASE, Web of Science, Medline and Google Scholar. All these results were computed using STATA 12.0 software. The random-effects models were used to calculate summary odds ratio (OR) or relative risk (RR) and 95% confidence interval (CI) when the heterogeneity was high; Inversely, the fixed-effects models were used to calculate summary OR/RR and 95% CI when the heterogeneity was low. RESULTS The present study showed that PCOS was significantly associated with an increased risk of GDM with a random effects model (OR/RR = 2.02, 95% CI 1.74 to 2.34, I2 = 79.5%, p < 0.0001). Subgroup analysis indicated an elevated risk of GDM in PCOS patients in both retrospective and prospective studies (retrospective studies: OR = 1.89, 95% CI 1.62 to 2.20; prospective studies: RR = 2.85, 95% CI 1.77 to 4.60). In addition, subgroup analysis indicated an elevated risk of GDM in PCOS patients in both Caucasian and Asian populations (Caucasian populations: OR/RR = 2.47, 95% CI 1.99 to 3.07; prospective studies: OR/RR = 1.58, 95% CI 1.23 to 2.02). CONCLUSION Overall, findings of the meta-analysis showed that women with PCOS have an elevated risk of GDM compared to women without PCOS. LIMITATIONS First, on account of sources of information, the role of several variables including BMI, the severity of GDM and serum lipid level in the association between PCOS and GDM can not be evaluated. Second, only studies published in English and Chinese were included, and the publish bias is impossible to avoid.

Abstract
During pregnancy, the fetoplacental unit is key in the pronounced physiological endocrine changes which support pregnancy, fetal development and survival, birth and lactation. In healthy women, pregnancy is characterized by changes in insulin sensitivity and increased maternal androgen levels. These are accompanied by a suite of mechanisms that support fetal growth, maintain glucose homeostasis and protect both mother and fetus from adverse effects of pregnancy induced insulin and androgen excess. In pregnancies affected by endocrine, metabolic disorders such as polycystic ovary syndrome (PCOS), diabetes and obesity, there is an imbalance of beneficial and adverse impacts of pregnancy induced endocrine changes. These inter-related conditions are characterized by an interplay of hyperinsulinemia and hyperandrogenism which influence fetoplacental function and are associated with adverse pregnancy outcomes including hypertensive disorders of pregnancy, macrosomia, preterm delivery and caesarean section. However, the exact underlying mechanisms and relationships of the endocrine and metabolic milieu in these disorders and the impact they have on the prenatal endocrine environment and developing fetus remain poorly understood. Here we aim to review the complex endocrine and metabolic interactions in healthy women during normal pregnancies and those in pregnancies complicated by hyperinsulinemic disorders (PCOS, diabetes and obesity). We also explore the relationships between these endocrine and metabolic differences and the fetoplacental unit, pregnancy outcomes and the developing fetus.

Abstract
PURPOSE OF REVIEW Cardiovascular disease (CVD) complications constitute about 50-70% of mortality in people with diabetes. However, there remains a persistently greater relative increase in CVD morbidity and mortality in women with diabetes than in their male counterparts. This review presents recent evidence for the risks, outcomes, and management implications for women with diabetes. RECENT FINDINGS Compared to men, women have higher BMI and more adverse cardiovascular risk profile at time of diabetes diagnosis with greater risk for coronary heart disease, stroke, vascular dementia, and heart failure. Pregnancy-specific risk factors of gestational diabetes and pre-eclampsia are associated with future type 2 diabetes (T2D) and CVD. Women with T2D may experience greater benefits than men from GLP-1 receptor agonists. Women with diabetes are at greater relative risk for CVD complications than men, with poorer outcomes, superimposed on preexisting gender disparities in social determinants of health, lower likelihood of being offered cardioprotective interventions, and enrollment in trials. Further research and the utilization of SGLT-2 inhibitors, GLP-1 receptor agonists, and other CVD prevention strategies will help reduce morbidity and mortality.

Abstract
Polycystic ovary syndrome (PCOS) is the most common endocrine condition affecting women. It has traditionally been viewed as a primarily reproductive disorder; however, it is increasingly recognized as a lifelong metabolic disease. Women with PCOS are at increased risk of insulin resistance (IR), type 2 diabetes mellitus, non-alcoholic fatty liver disease and cardiovascular disease. Although not currently a diagnostic criterion, IR is a cardinal pathophysiological feature and highly prevalent in women with PCOS. Androgens play a bidirectional role in the pathogenesis of IR, and there is a complex interplay between IR and androgen excess in women with PCOS. Skeletal muscle has a key role in maintaining metabolic homeostasis and is also a metabolic target organ of androgen action. Skeletal muscle is the organ responsible for the majority of insulin-mediated glucose disposal. There is growing interest in the relationship between skeletal muscle, androgen excess and mitochondrial dysfunction in the pathogenesis of metabolic disease in PCOS. Molecular mechanisms underpinning defects in skeletal muscle dysfunction in PCOS remain to be elucidated, but may represent promising targets for future therapeutic intervention. In this review, we aim to explore the role of skeletal muscle in metabolism, focusing particularly on perturbations in skeletal muscle specific to PCOS as observed in recent molecular and in vivo human studies. We review the possible role of androgens in the pathophysiology of skeletal muscle abnormalities in PCOS, and identify knowledge gaps, areas for future research and potential therapeutic implications. Despite increasing interest in the area of skeletal muscle dysfunction in women with PCOS, significant challenges and unanswered questions remain, and going forward, novel innovative approaches will be required to dissect the underlying mechanisms.

Abstract
PURPOSE The risk of hypertensive disorders of pregnancy (HDP) in women with polycystic ovary syndrome (PCOS) is inconsistent in some studies. The aim of this meta-analysis was to examine the evidence regarding the strength of the association between PCOS and HDP. METHODS PubMed, Web of Science, Embase, and the Cochrane Library were systematically searched to identify observational studies investigating HDP in patients with PCOS. The primary outcome was the pooled odds ratio (OR) of HDP, including pregnancy-induced hypertension (PIH) and pre-eclampsia (PE), in women with PCOS compared with the non-PCOS population. RESULTS A total of 30 studies were eligible for meta-analysis. PCOS was associated with a higher risk of HDP (OR 2.02, 95CI% 1.83-2.22), including PIH (OR 1.94, 95CI% 1.70-2.21), and PE (OR 2.07, 95CI% 1.91-2.24). The association remained significant after adjusting for age, body mass index (BMI), and nulliparity (HDP: OR 1.48, 95CI% 1.48-1.60; PIH: OR 1.42, 95%CI 1.29-1.57; PE: OR 2.07, and 95%CI 1.91-2.24). The increased risk of HDP for the PCOS group remained significant in subgroups of BMI, Age, singleton pregnancy, multiple pregnancy, gestational diabetes mellitus (GDM), hyperandrogenism, and nulliparity, while the finding was not observed in subgroups of nonhyperandrogenic and non-GDM. In the meta-regression, BMI contributed significantly to the heterogeneity in the prevalence of HDP. CONCLUSIONS PCOS is independently associated with a significantly increased risk of HDP. To prevent HDP during pregnancy, our findings highlight the importance of establishing supervision guidelines for PCOS patients, especially in the population with hyperandrogenism and GDM.

Abstract
PURPOSE The exact risk of type 2 diabetes mellitus (T2DM) in women with polycystic ovary syndrome (PCOS) is unknown. It is also unclear if obesity independently increases T2DM risk in this population. The aim of this study was to systematically review and synthesize the best available evidence regarding the association between PCOS and T2DM, stratified according to obesity status. METHODS A comprehensive search was conducted in PubMed, CENTRAL and Scopus databases up to October 31, 2020. Data are expressed as relative risk (RR) with 95% confidence interval (CI). The I2 index was employed for heterogeneity. RESULTS The eligibility criteria were fulfilled by 23 studies (319,780 participants; 60,336 PCOS and 8847 type 2 diabetes cases). Women with PCOS demonstrated a higher risk of T2DM than those without PCOS (RR 3.45, 95% CI, 2.95-4.05, p < 0.001; I2 81.6%). This risk remained significant both in studies matched or unmatched for participants' age. With regard to body mass index (BMI), the RR for developing T2DM in obese and non-obese PCOS women compared with their non-PCOS counterparts was 3.24 (95% CI 2.25-4.65; p < 0.001; I2 30.9%) and 1.62 (95% CI 0.14-18.50; p = 0.70; I2 89.9%), respectively. The RR for developing T2DM was 3.85 (95% CI 1.99-7.43; p < 0.001; I2 46.2%) in obese compared with non-obese women with PCOS. This was also the case for overweight compared with lean women with PCOS. CONCLUSIONS Women with PCOS present an increased risk of T2DM compared with non-PCOS women only if they are obese/overweight.

Abstract
Polycystic ovary syndrome (PCOS) is the most common endocrinopathy in women, affecting up to 15% of the female population. The natural history of the syndrome is complex, including both androgen exposure in early life and adiposity-driven dysfunction involving also dysregulated, also involving altered hypothalamus-ovarian crosstalk. The manifestations can arise as early as childhood or puberty onward, suggesting that genetic susceptibility is an important etiological factor. In adulthood, women with PCOS present with reproductive, metabolic, and psychological health issues at a population-based level. Epidemiological studies on large datasets offer an excellent opportunity to evaluate health effects and costs related to the syndrome. Hospital or insurance-based datasets are also available; however, the results are not representative of the female population in the community. More longitudinal studies spanning from early childhood to late adulthood are needed to assess the long-term health impact and early manifestations of PCOS. Moreover, the identification of women with PCOS from large datasets can be expensive. Self-reported symptoms or PCOS diagnosis may offer a feasible approach.

Abstract
OBJECTIVES A higher risk of hypertensive disorders in pregnancy (HDP) is frequently reported in women with polycystic ovary syndrome (PCOS). These women, however, have a higher risk profile for HDP compared with women without PCOS. The aim of this study was to elucidate the impact of PCOS per se on the incidence of HDP through post hoc subgroup analyses of the Australian Longitudinal Study on Women's Health by level of risk. DESIGN Longitudinal study. PATIENTS Of a total of 14,247 participants, 5838 women met the inclusion criteria. Eligible women were required to report PCOS and HDP status in at least one pregnancy within the study. MEASUREMENTS Included risk factors were age, body mass index, country of birth, parity, multiple pregnancy, subfertility, infertility treatment (hormonal vs. in vitro fertilization), gestational diabetes (GDM), family history of GDM and socioeconomic status. Longitudinal association between PCOS and HDP was assessed the using Cox proportional hazard regression with Efron's method. RESULTS While PCOS was associated with a higher incidence of HDP in a univariate model [hazard ratio (HR): 1.34, 95% confidence interval (CI): 1.05, 1.72], the significance was not retained after adjustment for risk factors [HR: 1.19, 95% CI: 0.79, 1.79]. However in multivariate analysis of subgroups, PCOS remained significantly associated with higher risk of HDP in non-obese women only [HR: 1.77, 95% CI: 1.11, 2.82]. CONCLUSIONS Higher risk of HDP in PCOS is likely related to risk factors other than PCOS.

Abstract
STUDY QUESTION Is there is an association between smoking and pregnancy complications in pregnant women with polycystic ovarian syndrome (PCOS)? SUMMARY ANSWER There is an increased risk of developing gestational diabetes mellitus (GDM) among women with PCOS who smoke. WHAT IS KNOWN ALREADY Smokers are at increased risk of developing Type 2 Diabetes Mellitus (DM). Given the common pathophysiology and shared risk factors between type 2 DM and GDM, we sought to assess whether an association between smoking and the development of GDM exists. STUDY DESIGN, SIZE, DURATION This is a retrospective population-based study utilizing data from the HCUP-NIS over 11 years from 2004 to 2014. Pregnant women with PCOS who did smoke were compared to pregnant women with PCOS who did not smoke. A second comparison was made between pregnant smokers with and without PCOS. Of the 443 590 women who smoked during pregnancy and the 14 882 women with PCOS, 631 women were both smokers and diagnosed with PCOS. PARTICIPANTS/MATERIALS, SETTING, METHODS The Healthcare Cost and Utilization Project-Nationwide Inpatient Sample (HCUP-NIS) is the largest inpatient sample database in the USA and is composed of hospital inpatient stays submitted by hospitals throughout the entire country. Each year, the database provides information relating to 7 million inpatient stays, including patient characteristics, diagnosis and procedures. The data are representative of ∼20% of admissions to US hospitals across 48 states and the District of Columbia. MAIN RESULTS AND THE ROLE OF CHANCE There were no differences in the risks of preterm delivery (aOR1.2; CI 0.8-1.9), placental abruption (aOR1.1; CI 0.4-3.2), pregnancy induced hypertension (aOR1.0; CI 0.7-1.5), rate of operative vaginal delivery (aOR1.5; CI 0.9-2.5) and rates of cesarean section (C/S) (aOR1.0; CI 0.7-1.3) between smoking and non-smoking women with PCOS. A significant association between smoking and GDM was observed in women with PCOS (aOR1.5; CI1.01-2.1). LIMITATIONS, REASONS FOR CAUTION The limitations of our study are its retrospective nature and the fact that it relies on an administrative database. Data regarding smoking and PCOS diagnosis could be skewed due to patients' underreporting, lack of documentation and documentation differences. WIDER IMPLICATIONS OF THE FINDINGS The public health implications of confirming smoking as a risk for GDM among women with PCOS are many. This can lead to earlier screening in pregnancy of smokers for GDM. Earlier initiation of interventions could decrease fetal complications and possibly have an impact on the life and long-term health of the offspring. Future studies are needed in order to assess whether smoking cessation during pregnancy decreases the risk of GDM in that gestation. STUDY FUNDING/COMPETING INTEREST(S) No external funding was used. The authors report no competing interests. TRIAL REGISTRATION NUMBER N/A.

Abstract
OBJECTIVES Given the adverse effects of either polycystic ovary syndrome (PCOS) or overweight/obesity, one could speculate that patients with both would fare worse than others. We sought to evaluate the relationship between pregravid BMI and pregnancy complications in PCOS patients conceived by assisted reproductive techniques (ART). METHODS Maternal and fetal/neonatal outcomes of singleton pregnancies after assisted reproduction in women with and without PCOS were compared by pregravid body mass index (BMI, <24.9 vs. ≥25 kg/cm2). RESULTS The study population comprised 185 with a BMI <24.9 kg/cm2 including 39 (21%) with PCOS and 146 (79%) without. We also included 84 patients with BMI ≥25 kg/cm2, involving 34 (40.5%) with PCOS and 50 (59.5%) without. PCOS (total 73 patients) was significantly more common among overweight/obese patients, OR 2.5 (95% CI 1.4, 4.4). Neonates >4,000 g were born only to the overweight/obese mothers in the PCOS group. A higher incidence of gestational diabetes, chronic hypertension, and gestational hypertension was related to pregravid overweight/obesity rather than PCOS. CONCLUSIONS In this specific subgroup of patients conceived after assisted reproduction, pregravid BMI>25 kg/cm2 rather than PCOS itself appears to be associated with GDM and hypertensive disorders.

Abstract
CONTEXT There are limited studies in large population-based settings examining the relationship between polycystic ovary syndrome (PCOS) and hypertension. OBJECTIVE To evaluate incidence of hypertension among women with and without PCOS over a 15-year period. DESIGN Secondary analysis of longitudinal data from the Australian Longitudinal Study on Women's Health. SETTING General community. PARTICIPANTS Women were randomly selected from the national health insurance database. 9508 women, aged 21-42 years, were followed up from 2000 to 2015. METHODS We conducted survival analysis using Cox proportional hazards model to identify predictors of hypertension and person-time analysis to calculate incidence rates of hypertension. RESULTS 9508 women were followed for 145 159 person years (PY), and 1556 (16.37%) women developed hypertension during follow-up. The incidence of hypertension was significantly higher (P = 0.001) among women with PCOS (17/1000 PY) compared to women without (10/1000 PY). Women with known PCOS status totaled 8223, of which 681 women (8.3%) had self-reported physician-diagnosed PCOS. Incidence rate difference of hypertension (cases attributable to PCOS) was 4-fold higher (15.8/1000 PY vs 4.3/1000 PY) among obese women with PCOS compared to age-matched lean women with PCOS. PCOS was independently associated with 37% greater risk of hypertension (hazard ratio 1.37, 95% confidence interval 1.14-1.65), adjusting for body mass index (BMI), family history of hypertension, occupation, and comorbidity with type 2 diabetes. CONCLUSIONS Women with PCOS are more likely to develop hypertension from early adulthood, independent of BMI, which is further exacerbated by obesity. Including PCOS in hypertension risk stratification assessments may aid efforts in early identification of the disorder.

Abstract
This review describes the relationship between obesity and the most common reproductive (infertility) and metabolic (gestational diabetes mellitus [GDM] and type 2 diabetes mellitus [T2DM]) consequences in polycystic ovary syndrome (PCOS). It also describes the vital role of lifestyle management for PCOS. PCOS is a heterogeneous endocrine disorder common in reproductive-age women. Consensus on the exact etiological mechanisms of PCOS is unreached. Overweight or obesity is present in at least 60% of the PCOS population, but the condition occurs irrespective of BMI, with excess BMI increasing both the prevalence and severity of clinical features. Use of lifestyle therapies (nutrition, physical activity, and/or behavioral) for the prevention and management of excess weight gain, infertility, GDM, and T2DM is a vital component of best-practice PCOS care. Lifestyle management is recommended for all women with PCOS as the first-line treatment with or without medications. Due to a lack of high-quality trials demonstrating the efficacy of specific lifestyle approaches, PCOS lifestyle recommendations are as those for the general population. This review summarizes current knowledge relating to obesity and its impact on fertility, GDM, and T2DM. It also summarizes the lifestyle recommendations to best manage these conditions in women with PCOS and obesity.

Abstract
BACKGROUND Girls with obesity and polycystic ovary syndrome (PCOS) and women with PCOS have altered gut microbiota. OBJECTIVE To study the gut microbiota composition of girls with PCOS without obesity (age, 15.8 years; body mass index [BMI] 25 kg/m2 ) and the effects of randomized treatments with an oral contraceptive (OC, N = 15) or with spironolactone-pioglitazone-metformin (SPIOMET, N = 15) for 1 year. Thirty-one age-matched girls served as controls. METHODS 16S ribosomal subunit gene amplicon sequencing was performed in stool samples from all subjects; samples from 23 out of 30 girls with PCOS (OC, N = 12; SPIOMET, N = 11) were available for analysis post-treatment. Clinical and endocrine-metabolic variables were measured before and after intervention. RESULTS Girls with PCOS had decreased diversity alpha, altered microbiota pattern and taxonomic profile with more abundance of Family XI (P = .002), and less abundance of family Prevotellaceae (P = .0006) the genus Prevotella (P = .0001) and Senegalimassilia (P < .0001), as compared to controls. Family XI abundance related positively to hepato-visceral fat (R = 0.453; P = .0003). SPIOMET treatment, but not OC, normalized the abundance of Family XI. Prevotellaceae, Prevotella and Senegalimassilia abundance remained unchanged after either treatment. CONCLUSION SPIOMET's spectrum of normalizing effects in girls with PCOS is herewith broadened as to include Family XI abundance in gut microbiota.

Abstract
OBJECTIVE To investigate the effects of acupuncture on ovary morphology and function in dehydroepiandrosterone (DHEA)-induced polycystic ovary syndrome (PCOS) model rats. METHODS A total of 40 adult female Wistar rats were randomly allocated to 4 groups by a random number table, including control, model, metformin and acupuncture groups, 10 rats in each group. PCOS rat model was developed by injecting with DHEA (6 mg/100 g body weight) in 0.2 mL of oil subcutaneously. Electrical stimulation (2 Hz, 3 mA) was applied to Guanyuan (CV 4), Zigong (EX-CA1) and Qihai (CV 6) acupoints for 30 min daily in the acupuncture group, and metformin (200 mg/kg) was given to rats in the metformin group, both once per day for 21 consecutive days, and rats in the normal group was fed with normal saline and fed regularly. After 21 days of administration, the rat blood samples were collected for detecting the reproductive hormonal levels [luteinizing hormone (LH), follicle stimulating hormone (FSH), estradiol (E2), progesterone (P), testosterone (T)] and inflammatory factors (visfatin, IL-6) analysis. Ovary tissue was used for histopathological analysis. RESULTS Compared with the model group, rats in the acupuncture and metformin groups were significantly lower in weight gain, FSH, LH and T levels, and E2 and P levels significantly increased (alll P<0.05). Meanwhile, LH and FSH levels were significantly decreased, and P, T and E2 levels significantly increased in the acupuncture group, compared with the metformin group (P<0.05). Compared with the model group, IL-6 and visfatin levels were significantly decreased in the acupuncture and metformin groups (P<0.05). There were no significant differences in IL-6 and visfatin levels between the acupuncture and metformin groups (P>0.05). Ovarian diameter in the acupuncture and metformin groups were smaller than the model group (P<0.05). However, there were no significant differences in ovarian diameters between the acupuncture and metformin groups (P>0.05). CONCLUSION Acupuncture might improve ovary morphology and its function in DHEA-induced PCOS model rats.

Abstract
OBJECTIVE To investigate the relationship between polycystic ovary syndrome (PCOS) and type 2 diabetes mellitus (T2DM) in Korean women. DESIGN Longitudinal case-control study. SETTING Not applicable. PATIENT(S) PCOS patients aged 15 to 44 years (n = 1,136) and control individuals (n = 5,675), matched 1:5 by age group, income, and region of residence. INTERVENTION(S) Not applicable. MAIN OUTCOME MEASURE(S) The occurrence of T2DM. RESULT(S) In the PCOS and control groups, 15.7% and 14.4%, respectively, were obese (body mass index ≥25 kg/m2). The incidence rate of T2DM was 15.84/1,000 and 5.80/1,000 person-years in the PCOS and control groups, respectively. The unadjusted hazard ratio (HR) of T2DM in women with PCOS was 2.6-fold higher than that in control individuals. Women with PCOS still had a higher HR of T2DM than did control individuals after adjustment for body mass index, family history of T2DM, physical exercise level, and total cholesterol. PCOS was significantly associated with T2DM in women both with and without obesity. CONCLUSION(S) PCOS is independently associated with an increased incidence of T2DM in both obese and nonobese women. Screening for T2DM should be considered for both obese and nonobese women with PCOS in Korea.

Are Dietary Indices Associated with Polycystic Ovary Syndrome and Its Phenotypes? A Preliminary Study. Nutrients 2021; 13:nu13020313. [PMID: 33499268 PMCID: PMC7911683 DOI: 10.3390/nu13020313] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/30/2020] [Revised: 01/13/2021] [Accepted: 01/20/2021] [Indexed: 12/25/2022] Open
Abstract
Polycystic ovary syndrome (PCOS) is a complex hormonal disorder which impairs ovarian function. The adherence to healthy dietary patterns and physical exercise are the first line of recommended treatment for PCOS patients, but it is yet unclear what type of diet is more adequate. In this case-control study, we explored associations between adherence to five dietary quality indices and the presence of PCOS. We enrolled 126 cases of PCOS and 159 controls living in Murcia (Spain). Diagnostic of PCOS and its phenotypes were established following the Rotterdam criteria (hyperandrogenism (H), oligoanovulation (O), polycystic ovaries morphology (POM)). We used a validated food frequency questionnaires to calculate the scores of five dietary indices: alternate Healthy Eating index (AHEI), AHEI-2010, relative Mediterranean Dietary Score (rMED), alternate Mediterranean Dietary Score (aMED) and Dietary Approaches to Stop Hypertension (DASH). We used multivariable logistic regression to estimate adjusted odds ratios and confidence intervals. In the multivariable analysis, AHEI-2010 index was inversely associated with Hyperandrogenism + Oligoanovulation PCOS phenotype (ORQ3 vs. Q1 = 0.1; 95% CI: (0.0; 0.9); Pfor trend = 0.02). We did not find any statistical significant association between dietary indices and total anovulatory or ovulatory PCOS. However, further studies with higher sample sizes exploring these associations among the diverse phenotypes of PCOS are highly warranted.

Maternal Overweight vs. Polycystic Ovary Syndrome: Disentangling Their Impact on Insulin Action in Pregnancy—A Prospective Study. J Clin Med 2020; 10:jcm10010035. [PMID: 33374430 PMCID: PMC7795887 DOI: 10.3390/jcm10010035] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/01/2020] [Revised: 12/20/2020] [Accepted: 12/21/2020] [Indexed: 11/16/2022] Open
Abstract
Background: To investigate insulin sensitivity and glucose metabolism in pregnant lean and overweight polycystic ovary syndrome (PCOS) patients vs. lean and overweight controls without PCOS. Methods: Prospective cohort study on 67 pregnant women (31 with PCOS and 36 controls, subdivided into overweight or obese and normal weight). All women underwent a 2h-OGTT including glucose, insulin, and C-peptide in early- and mid-gestation and were followed-up until delivery. Results: Insulin sensitivity and glucometabolic parameters were comparable between PCOS patients and controls, whereas marked differences were observed between overweight/obese and lean mothers. Impaired whole-body insulin sensitivity at early pregnancy is mainly a consequence of higher BMI (body mass index; p < 0.001) compared to PCOS (p = 0.216), whereby no interaction between overweight/obesity and PCOS was observed (p = 0.194). Moreover, overweight was significantly associated with gestational diabetes (p = 0.0003), whereas there were no differences between women with and without PCOS (p = 0.51). Birth weight was inversely related to whole-body insulin sensitivity (rho = −0.33, p = 0.014) and positively associated with higher pregestational BMI (rho = 0.33, p = 0.012), whereas there was no association with PCOS. Conclusions: Impaired insulin action was mainly a consequence of overweight rather than PCOS. Our data suggest that overweight is more relevant than PCOS for the effects on insulin sensitivity and impaired glucose metabolism.

Abstract
BACKGROUND This study estimated the cost-effectiveness of metformin to reduce the risk of gestational diabetes mellitus (GDM) in pregnant women with polycystic ovary syndrome (PCOS) from the US health-care payer perspective. METHODS A decision tree was developed to simulate the progression of PCOS in a hypothetical cohort of 10,000 pregnant women diagnosed with PCOS and two scenarios were tested. Normal glucose regulation without developing GDM, average cost-effectiveness ratios (ACER), and the incremental cost-effectiveness ratios (ICERs) were the outcome measures assessed through pregnancy. Evidence from randomized clinical trials and other published literature were used to assess disease progression and its associated health-care costs. Sensitivity analyses that varied key model parameters were conducted. RESULTS Management of PCOS with metformin was associated with lowest ACER ($669.78 per normal glucose regulation without GDM) as compared to 'no intervention' strategy. Metformin use is the most cost-effective strategy to manage PCOS during pregnancy with average cost savings of $7,593,372.97 and an average effect gain of 2271 of normal glucose regulation without GDM among pregnant women with PCOS. Sensitivity analyses determined that the results are robust. CONCLUSIONS Management of PCOS during pregnancy may be a cost-effective strategy to reduce GDM risk and its associated complications.

Abstract
BACKGROUND AND AIMS Metabolic syndrome (MetS) and polycystic ovary syndrome (PCOS) are two interrelated but distinct endocrine problems with several health consequences secondary to insulin resistance. This study aimed to determine the prevalence of MetS in women with PCOS. METHODS This was a cross sectional study carried out from May 2017 to October 2017 at the gynecology outpatient clinic of a tertiary care private hospital in Hyderabad, India. Eligible women diagnosed with PCOS according to Rotterdam criteria were enrolled. The primary outcome was the prevalence of MetS diagnosed by the modified NCEP ATP III criteria. RESULTS The study comprised 382 patients with a mean age of 26.8 ± 5.3 years. MetS was present in 147 (38.5%) women with PCOS. The most frequently observed individual components of MetS were increased waist circumference and decreased HDL cholesterol. When predictors for MetS were analyzed by multivariate regression, BMI (aOR 1.14; 1.06-1.23; p ≪0.001) and age (aOR 1.12; 1.06-1.17; p ≪0.001) were significantly associated with MetS; however, the effect size was modest. CONCLUSION A high prevalence of MetS was observed in women with PCOS at this tertiary center in Hyderabad, with abdominal obesity and low HDL cholesterol as predominant components. We believe that universal screening of all PCOS women is a reasonable option.

Abstract
OBJECTIVE Polycystic ovary syndrome (PCOS) is associated with an increased prevalence of dysglycaemia, which includes impaired glucose tolerance and type 2 diabetes mellitus (T2DM). Patients with PCOS demonstrate abnormal patterns of steroid hormones. Here, we analyse the correlation between glucose metabolism and serum steroid hormones in PCOS. DESIGN Observational double-centre study. PATIENTS 914 patients with PCOS. MEASUREMENTS We assessed the glucose metabolism status of all patients according to the 1999 WHO criteria. Serum steroid hormones were measured by liquid chromatography-tandem mass spectrometry. RESULTS The median age of the patients was 26 years (interquartile range: 21-30), and 40.6% (371/914) had abnormal glucose metabolism: 29.3% (268/914) had prediabetes, and 11.3% (103/914) had T2DM. Correlation analysis not adjusting for confounding factors revealed that serum aldosterone, androstenedione, oestrone, pregnenolone and the free androgen index were positively correlated, while progesterone was negatively correlated with the risk of abnormal glucose metabolism. After adjusting for age, body mass index and fasting insulin levels in the logistic regression model, only aldosterone (P = .013), androstenedione (P = .046) and oestrone (P = .014; in quartiles) were correlated with the risk of abnormal glucose metabolism. CONCLUSIONS This study indicates a high prevalence of prediabetes and T2DM in patients with PCOS. Furthermore, there were positive correlations of serum aldosterone, androstenedione and oestrone with the risk of abnormal glucose metabolism after adjusting for confounding factors.

Abstract
Reproductive dysfunction is a common but little studied complication of diabetes. The spectrum of reproductive health problems in diabetes is broad, and encompasses delayed puberty and menarche, menstrual cycle abnormalities, subfertility, adverse pregnancy outcomes, and potentially early menopause. Depending on the age at diagnosis of diabetes, reproductive problems can manifest early on in puberty, emerge later when fertility is desired, or occur during the climacteric period. Historically, women with type 1 diabetes have frequently had amenorrhoea and infertility, due to central hypogonadism. With the intensification of insulin therapy and improved metabolic control, these problems have declined, but do persist. Additional reproductive implications of contemporary diabetes management are now emerging, including polycystic ovary syndrome and hyperandrogenism, which are underpinned by insulin action on the ovary. The sharp rise in type 2 diabetes incidence in youth suggests that more women of reproductive age will encounter diabetes-related reproductive problems in their lifetimes. With an ever increasing number of young women living with diabetes, clinicians need to be aware of and equipped for the challenges of navigating reproductive health concerns across the lifespan.

Abstract
Polycystic ovary syndrome (PCOS) has been traditionally perceived as a reproductive disorder due to its most common presentation with menstrual dysfunction and infertility. However, it is now clear that women with PCOS are at increased risk of metabolic dysfunction, from impaired glucose tolerance and type 2 diabetes mellitus to nonalcoholic fatty liver disease and cardiovascular disease. PCOS is characterised by androgen excess, with cross-sectional data showing that hyperandrogenism is directly complicit in the development of metabolic complications. Recent studies have also shown that C11-oxy C19 androgens are emerging to be clinically and biochemically significant in PCOS, thus emphasising the importance of understanding the impact of both classic and C11-oxy C19 androgens on women's health. Here we discuss androgen metabolism in the context of PCOS, and dissect the role played by androgens in the development of metabolic disease through their effects on metabolic target tissues in women.

Abstract
RESEARCH QUESTION Polycystic ovary syndrome (PCOS) is a complex endocrine disorder with diverse clinical implications, such as infertility, metabolic disorders, cardiovascular diseases and psychological problems among others. The heterogeneity of conditions found in PCOS contribute to its various phenotypes, leading to difficulties in identifying proteins involved in this abnormality. Several studies, however, have shown the feasibility in identifying molecular evidence underlying other diseases using graph cluster analysis. Therefore, is it possible to identify proteins and pathways related to PCOS using the same approach? METHODS Known PCOS-related proteins (PCOSrp) from PCOSBase and DisGeNET were integrated with protein-protein interactions (PPI) information from Human Integrated Protein-Protein Interaction reference to construct a PCOS PPI network. The network was clustered with DPClusO algorithm to generate clusters, which were evaluated using Fisher's exact test. Pathway enrichment analysis using gProfileR was conducted to identify significant pathways. RESULTS The statistical significance of the identified clusters has successfully predicted 138 novel PCOSrp with 61.5% reliability and, based on Cronbach's alpha, this prediction is acceptable. Androgen signalling pathway and leptin signalling pathway were among the significant PCOS-related pathways corroborating the information obtained from the clinical observation, where androgen signalling pathway is responsible in producing male hormones in women with PCOS, whereas leptin signalling pathway is involved in insulin sensitivity. CONCLUSIONS These results show that graph cluster analysis can provide additional insight into the pathobiology of PCOS, as the pathways identified as statistically significant correspond to earlier biological studies. Therefore, integrative analysis can reveal unknown mechanisms, which may enable the development of accurate diagnosis and effective treatment in PCOS.

Progression of glucose intolerance and cardiometabolic risk factors over a decade in Chinese women with polycystic ovary syndrome: A case-control study. PLoS Med 2019; 16:e1002953. [PMID: 31652273 PMCID: PMC6814217 DOI: 10.1371/journal.pmed.1002953] [Citation(s) in RCA: 31] [Impact Index Per Article: 6.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/28/2019] [Accepted: 09/25/2019] [Indexed: 12/21/2022] Open
Abstract
BACKGROUND Polycystic ovary syndrome (PCOS) is associated with increased metabolic risk, though data on long-term follow-up of cardiometabolic traits are limited. We postulated that Chinese women with PCOS would have higher risk of incident diabetes and cardiometabolic abnormalities than those without PCOS during long-term follow-up. METHODS AND FINDINGS One hundred ninety-nine Chinese women with PCOS diagnosed by the Rotterdam criteria and with a mean age of 41.2 years (SD = 6.4) completed a follow-up evaluation after an average of 10.6 ± 1.3 years. Two hundred twenty-five women without PCOS (mean age: 54.1 ± 6.7 years) who underwent baseline and follow-up evaluation over the same period were used for comparison. Progression of glycaemic status of women both with and without PCOS was assessed by using 75-g oral glucose tolerance test (OGTT) screening with the adoption of 2009 American Diabetes Association diagnostic criteria. The frequency of impaired glucose regulation, hypertension, and hyperlipidaemia of women with PCOS at follow-up has increased from 31.7% (95% CI 25.2%-38.1%) to 47.2% (95% CI 40.3%-54.2%), 16.1% (95% CI 11.0%-21.2%) to 34.7% (95% CI 28.1%-41.3%), and 52.3% (95% CI 45.3%-59.2%) to 64.3% (95% CI 57.7%-71.0%), respectively. The cumulative incidence of diabetes mellitus (DM) in follow-up women with PCOS is 26.1% (95% CI 20.0%-32.2%), almost double that in the cohort of women without PCOS (p < 0.001). Age-standardised incidence of diabetes among women with PCOS was 22.12 per 1,000 person-years (95% CI 10.86-33.37) compared with the local female population incidence rate of 8.76 per 1,000 person-years (95% CI 8.72-8.80) and 10.09 per 1,000 person-years (95% CI 4.92-15.26, p < 0.001) for women without PCOS in our study. Incidence rate for women with PCOS aged 30-39 years was 20.56 per 1,000 person-years (95% CI 12.57-31.87), which is approximately 10-fold higher than that of the age-matched general female population in Hong Kong (1.88 per 1,000 person-years, [95% CI 1.85-1.92]). The incidence rate of type 2 DM (T2DM) of both normal-weight and overweight women with PCOS was around double that of corresponding control groups (normal weight: 8.96 [95% CI 3.92-17.72] versus 4.86 per 1,000 person-years [95% CI 2.13-9.62], p > 0.05; overweight/obese: 28.64 [95% CI 19.55-40.60] versus 14.1 per 1,000 person-years [95% CI 8.20-22.76], p < 0.05). Logistic regression analysis identified that baseline waist-to-hip ratio (odds ratio [OR] = 1.71 [95% CI 1.08-2.69], p < 0.05) and elevated triglyceride (OR = 6.63 [95% CI 1.23-35.69], p < 0.05) are associated with the progression to T2DM in PCOS. Limitations of this study include moderate sample size with limited number of incident diabetes during follow-up period and potential selection bias. CONCLUSIONS High risk of diabetes and increased cardiovascular disease risk factors among Chinese women with PCOS are highlighted in this long-term follow-up study. Diabetes onset was, on average, 10 years earlier among women with PCOS than in women without PCOS.

Abstract
Based on clinical observations, women with polycystic ovarian syndrome (PCOS) are prone to developing several other diseases, such as metabolic and cardiovascular diseases. However, the molecular association between PCOS and these diseases remains poorly understood. Recent studies showed that the information from protein-protein interaction (PPI) network analysis are useful in understanding the disease association in detail. This study utilized this approach to deepen the knowledge on the association between PCOS and other diseases. A PPI network for PCOS was constructed using PCOS-related proteins (PCOSrp) obtained from PCOSBase. MCODE was used to identify highly connected regions in the PCOS network, known as subnetworks. These subnetworks represent protein families, where their molecular information is used to explain the association between PCOS and other diseases. Fisher's exact test and comorbidity data were used to identify PCOS-disease subnetworks. Pathway enrichment analysis was performed on the PCOS-disease subnetworks to identify significant pathways that are highly involved in the PCOS-disease associations. Migraine, schizophrenia, depressive disorder, obesity, and hypertension, along with twelve other diseases, were identified to be highly associated with PCOS. The identification of significant pathways, such as ribosome biogenesis, antigen processing and presentation, and mitophagy, suggest their involvement in the association between PCOS and migraine, schizophrenia, and hypertension.

Abstract
Background To assess the extent to which multiple gestations mediate risk of pregnancy complications from fertility treatment and to address possible confounding by the underlying infertility. Methods From the nearly 1.8 million pregnancies recorded in the Swedish Medical Birth Register between 1996 and 2013, we selected the 9.9% (N = 174 067) that occurred to couples with known trouble conceiving (clinical infertility). Fertility treatment was identified from self-reports, medical records and procedural information from fertility clinics. We used logistic regression to estimate odds ratios (ORs) and their 95% confidence intervals (CIs), and decomposed the total effect into direct and mediated effects to estimate the proportion mediated by multiple gestations. Results Compared with pregnancies achieved without any assistance, those having received some treatment had higher odds of all studied complications except gestational diabetes. Associations with placenta previa (OR 2.17, 95% CI 1.95-2.40) and placental abruption (OR 1.77, 95% CI 1.54-2.03) were almost entirely independent of multiple gestations. In contrast, the majority of the associations with preterm birth (OR 1.69, 95% CI 1.62-1.77), caesarean delivery (RR 1.15, 95% CI 1.13-1.17) and pre-eclampsia (OR 1.17, 95% CI 1.11-1.22) were mediated by multiple gestations (87%, 62% and 91% of the effect mediated, respectively). Both direct and mediated pathways contributed to the remaining positive associations with chorioamnionitis, labour induction and postpartum haemorrhage. Results were similar when considering primi- and multi-parous women separately, and after restriction to assisted reproductive technologies only. Conclusion Multiple gestations are responsible for a large proportion of pregnancy complications associated with fertility treatment, suggesting that interventions to restrict the occurrence of multiples could reduce excess risk of pre-eclampsia, preterm birth and caesarean delivery after fertility treatment. However, the elevated risk of serious placental complications after fertility treatment appears to be largely independent of multiple gestations.

Abstract
Maternal PCOS status may negatively influence offspring infant and childhood growth, cardiometabolic health, reproductive health, and neurodevelopment. Current findings across studies are divergent, often because of small numbers of subjects, as well as heterogeneous selection criteria, ethnicities, and definitions of control groups. Coexisting maternal obesity, pregnancy complications, and comorbidity make it difficult to identify the contribution of maternal PCOS. Large, prospective, international, multiethnic studies with standardized investigation protocols and questionnaires on PCOS offspring health and development are needed.

Abstract
S100A4 is a marker of subcutaneous adipose tissue dysfunction. Polycystic ovary syndrome (PCOS) is often driven by hepato-visceral adiposity. PCOS phenotypes are normalized more by reduction of central fat with spironolactone/pioglitazone/metformin (SPIOMET) than by oral contraceptive (OC) treatment. We studied whether circulating S100A4 concentrations are high in adolescents with PCOS and, if so, whether they normalize more with OC or SPIOMET. Assessments included circulating S100A4, endocrine markers, body composition, abdominal fat partitioning in controls (n = 12) and girls with PCOS (n = 51; age 15.8 y; body mass index [BMI] 24.5 kg/m2 ), and 1-year changes in girls with PCOS randomized for OC (n = 27) or SPIOMET (n = 24) treatment. Mean S100A4 concentrations were 71% higher (P < 0.001) in girls with PCOS than in controls and associated with hepato-visceral adiposity (r = 0.47; P = 0.001); S100A4 concentrations decreased more (P < 0.01) with SPIOMET, those decreases associating to hepato-visceral fat loss (r = 0.50; P < 0.0001). S100A4 may become a circulating marker of hepato-visceral fat excess in adolescents with PCOS.

Abstract
Polycystic ovary syndrome (PCOS) is associated with an increased risk of maternal pregnancy and delivery complications. However, the impact of clinical features of PCOS and other potential risk factors in PCOS is still unknown. We aimed to investigate the association of PCOS with maternal pregnancy and delivery complications with consideration of risk factors and potential confounders. The meta-analysis included 63 studies. PCOS was associated with higher miscarriage, gestational diabetes mellitus, gestational hypertension, pre-eclampsia, induction of labour, and caesarean section. The association of PCOS with these outcomes varied by geographic continent, PCOS phenotypes, and study quality. Pre-eclampsia and induction of labour were not associated with PCOS on body mass index-matched studies. No outcome was associated with PCOS on assisted pregnancies. Age was significantly associated with higher miscarriage on meta-regression. There were no studies assessing perinatal depression. We confirm that PCOS is associated with an increased risk of maternal pregnancy and delivery complications. The association of PCOS with the outcomes is worsened in hyperandrogenic PCOS phenotypes, in specific geographic continents, and in the highest quality studies but disappears in assisted pregnancies. Future studies in PCOS are warranted to investigate proper timing for screening and prevention of maternal pregnancy and delivery complications with consideration of clinical features of PCOS.

Abstract
OBJECTIVE The nature of the independent relationship between polycystic ovary syndrome (PCOS) and type 2 diabetes remains unclear. Few studies have aimed to clarify this relationship independent of obesity in longitudinal population-based cohorts. RESEARCH DESIGN AND METHODS We used the Australian Longitudinal Study on Women's Health (ALSWH) (2000-2015) database to estimate nationwide incidence rates and predictors of type 2 diabetes among women aged 18-42 using person-time and survival analysis. RESULTS Over a follow-up of 1,919 person-years (PYs), 186 women developed type 2 diabetes. The incidence rate was 4.19/1,000 PYs and 1.02/1,000 PYs (P < 0.001) in PCOS and control subjects. On subgroup analyses across healthy-weight, overweight, and obese categories of women, the incidence rates for type 2 diabetes were 3.21, 4.67, and 8.80, whereas incidence rate ratios were 4.68, 3.52, and 2.36 (P < 0.005) in PCOS versus age-matched control subjects. PCOS was one of the most influential predictors for type 2 diabetes in the entire cohort (hazard ratio 3.23, 95% CI 2.07-5.05, P < 0.001) adjusting for BMI, education, area of residence, and family history of type 2 diabetes. CONCLUSIONS Women with PCOS are at an increased risk of type 2 diabetes, irrespective of age and BMI. The incidence of type 2 diabetes increases substantially with increasing obesity; yet, PCOS adds a greater relative risk in lean women. Based on the overall moderate absolute clinical risk demonstrated here, guideline recommendations suggest type 2 diabetes screening every 1-3 years in all women with PCOS, across BMI categories and age ranges, with frequency influenced by additional type 2 diabetes risk factors.

Diagnosis of disorders of glucose tolerance in women with polycystic ovary syndrome (PCOS) at a tertiary care center: fasting plasma glucose or oral glucose tolerance test? Metabolism 2019; 93:86-92. [PMID: 30710572 DOI: 10.1016/j.metabol.2019.01.015] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/06/2018] [Revised: 01/22/2019] [Accepted: 01/26/2019] [Indexed: 12/18/2022]
Abstract
BACKGROUND The risk of developing prediabetes and type 2 diabetes (dysglycemia) may be increased in women with PCOS. Whether an oral glucose tolerance test (OGTT) should be performed routinely in all PCOS women at presentation or should be recommended only to a selected subset of patients is still controversial. BASIC PROCEDURES At a tertiary care center, we conducted a retrospective, observational study including 400 women with PCOS submitted to an OGTT. Our primary objective was to assess the diagnostic agreement between two algorithms commonly used for the screening of dysglycemia in these women: i) relying only on fasting plasma glucose (FPG) or ii) considering both fasting and/or 120-min plasma glucose concentrations during an OGTT. We conducted the analysis considering all patients as a whole, and also after stratifying them by body weight, androgen concentrations and age. MAIN FINDINGS The OGTT detected dysglycemia in 24.5% of patients, whereas only 14.3% women would have been diagnosed using FPG levels alone. The latter missed as many as 40% of women with dysglycemia in our series, including all cases of diabetes. Diagnostic agreement between both algorithms was only 0.55 (κ = 0.103; 95% CI: 0.05-0.16). Areas under the receiver operating characteristic curve for dysglycemia were 0.86 (95%CI: 0.81-0.91) for FPG and 0.91 (95%CI = 0.87-0.95) for 120-min plasma glucose during the OGTT. FPG was not accurate in predicting dysglycemia in women with PCOS regardless of the presence of insulin resistance, weight excess, hyperandrogenemia and age. PRINCIPAL CONCLUSIONS Relying on FPG alone is not adequate for the screening of disorders of glucose tolerance in women with PCOS; such diagnosis should rely on the results of an OGTT regardless of age, weight and/or androgen concentrations.

Abstract
OBJECTIVE Many complex diseases exhibit co-morbidities often requiring management by more than one health specialist. We examined cross-speciality issues that ultimately affect the health and wellbeing of patients with polycystic ovary syndrome (PCOS). PCOS was originally described as a reproductive condition but is now recognised to also be a metabolic and psychological condition affecting 8-13% of women of reproductive age. With a four-fold increased risk of type 2 diabetes (DM2), the Population Attributable Risk of DM2 that could be avoided if PCOS were eliminated is a substantial 19-28% of women of reproductive age. To determine the extent to which PCOS is an important consideration in diabetes development, we examined publications, funding, guidelines and predictors of risk of developing DM2. RESULTS We found that the topic of PCOS appeared in specialist diabetes journals at only 10% the rate seen in endocrinology journals - about 1 in 500 articles. We found research funding to be substantially less than for diabetes and found that diabetes guidelines and predictive tools for DM2 risk mostly ignore PCOS. This is surprising since insulin resistance in women with PCOS has a different aetiology and additionally women with PCOS are at increased risk of becoming overweight or obese - high risk factors for DM2. CONCLUSIONS We consider the causes of these concerning anomalies and discuss current activities to address the co-morbidities of PCOS, including the recent development of international guidelines, an international PCOS awareness program and potentially changing the name of PCOS to better reflect its metabolic consequences.

Abstract
Data on the effects of magnesium and vitamin E co-supplementation on glycemic control and markers of cardio-metabolic risk of patients with polycystic ovary syndrome (PCOS) were collected. This investigation was conducted to evaluate the effects of magnesium and vitamin E co-supplementation on glycemic control and markers of cardio-metabolic risk in women with PCOS. This randomized, double-blind, placebo-controlled trial was carried out on 60 women with PCOS, aged 18-40 years old. Participants were randomly divided into two groups to receive 250 mg/day magnesium plus 400 mg/day vitamin E supplements or placebo (n=30 each group) for 12 weeks. Fasting blood samples were taken at baseline and after the 12-week intervention to quantify related variables. After the 12-week intervention, compared with the placebo, magnesium and vitamin E co-supplementation led to a significant reduction in serum insulin levels (-1.1±3.0 vs. +1.6±3.7 μIU/ml, p=0.003) and homeostatic model of assessment for insulin resistance (-0.2±0.7 vs. +0.4±0.9, p=0.002), and a significant increase in the quantitative insulin sensitivity check index (+0.01±0.01 vs. -0.009±0.02, p=0.003). Furthermore, magnesium plus vitamin E supplementation significantly decreased serum triglycerides (-15.0±24.4 vs. +6.7±22.2 mg/dl, p=0.001) and VLDL-cholesterol concentrations (-3.0±4.9 vs. +0.6±2.4 mg/dl, P=0.01) compared with the placebo. A trend toward a greater decrease in total cholesterol levels was observed in magnesium plus vitamin E group compared to placebo group (-7.0±32.6 vs. +8.1±26.6 mg/dl, p=0.05). In conclusion, magnesium and vitamin E co-supplementation for 12 weeks to PCOS women had beneficial effects on parameters of insulin metabolism and few markers of cardio-metabolic risk.
