Abstract
It is unclear whether polycystic ovary syndrome (PCOS) is an independent risk factor for adverse birth outcomes in the offspring of affected women. Here, we investigate the association of PCOS with birth outcomes in the offspring of women with PCOS overall and by potential confounders. This systematic review and meta-analysis included 73 studies and 92,881 offspring of women with and without PCOS from inception until 13th July 2022. We report that mothers with PCOS are younger and have higher body mass index (BMI) around conception and have greater gestational weight gain. The odds of preterm birth, fetal growth restriction and low birth weight are higher and mean birthweight is lower in PCOS of which a lower mean birthweight and a higher small for gestational age are probably independent of BMI. This work informed the recommendations from the 2023 international evidence-based guideline for the assessment and management of polycystic ovary syndrome, emphasizing that PCOS status should be captured at pregnancy to identify risk and improve birth outcomes in the offspring.

Abstract
Screening for polycystic ovary syndrome (PCOS) in antenatal care is inadequate, largely owing to the lack of clarity around whether PCOS is an independent risk factor for pregnancy complications. This systematic review and meta-analysis include 104 studies and 106,690 pregnancies in women with and without PCOS from inception until 13th July 2022. We report that women with PCOS are younger and have higher body mass index (BMI) around conception and have greater gestational weight gain. The odds of miscarriage, gestational diabetes mellitus, gestational hypertension, pre-eclampsia and cesarean section are higher in women with PCOS. The increased odds of adverse outcomes in PCOS remain significant when age and BMI are matched and when analyses are restricted to high-quality studies. This work informed the recommendations from the 2023 international evidence-based guideline for the assessment and management of polycystic ovary syndrome, emphasizing that PCOS status should be captured in all women who are planning to, or have recently become pregnant to facilitate prevention of adverse outcomes and improve pregnancy outcomes.

Abstract
INTRODUCTION Polycystic ovary syndrome (PCOS) is a globally prevalent endocrinological disorder and has been associated with poor pregnancy outcomes, including a higher rate of gestational diabetes and miscarriage. Metformin is among the drugs investigated to improve the prognosis of pregnant women with PCOS. OBJECTIVE To conduct an overview of systematic reviews examining the effects of metformin versus placebo or no intervention throughout pregnancy among pregnant women with a preconception PCOS diagnosis to reduce the incidence of miscarriage and gestational diabetes. METHODS AND ANALYSIS We will perform an overview of systematic reviews by searching Embase, PubMed, Virtual Health Library, Cochrane Central Register of Controlled Trials, Trip Database, Scopus, Web of Science and Cumulative Index to Nursing and Allied Health Literature from inception to 17 August 2023. Language, publication status and year indexed or published filters will not be applied. Two reviewers will independently screen and select papers, assess their quality, evaluate their risk of bias and collect the data. The included reviews will be summarised narratively. The quality and risk of bias of the systematic review and meta-analysis studies included will be assessed using AMSTAR 2 (A Measurement Tool to Assess Systematic Reviews, Second Version) and ROBIS (Risk of Bias in Systematic Reviews), respectively. ETHICS AND DISSEMINATION This overview of reviews will analyse data from systematic reviews on the use of metformin for prepregnancy diagnosis of PCOS to reduce adverse outcomes. As there will be no primary data collection, a formal ethical analysis is unnecessary. The study outcomes will be submitted to a peer-reviewed journal and presented at conferences. PROSPERO REGISTRATION NUMBER CRD42023441488.

Investigating the causal impact of polycystic ovary syndrome on gestational diabetes mellitus: a two-sample Mendelian randomization study. Front Endocrinol (Lausanne) 2024; 15:1337562. [PMID: 38375192 PMCID: PMC10875069 DOI: 10.3389/fendo.2024.1337562] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/13/2023] [Accepted: 01/16/2024] [Indexed: 02/21/2024] Open
Abstract
Introduction Determining the causal relationship between polycystic ovary syndrome (PCOS) and gestational diabetes mellitus (GDM) holds significant implications for GDM prevention and treatment. Despite numerous observational studies suggesting an association between PCOS and GDM, it remains unclear whether a definitive causal relationship exists between these two conditions and which specific features of PCOS contribute to increased incidence of GDM. Methods The causal relationship between polycystic ovary syndrome (PCOS), its characteristic indices, and gestational diabetes mellitus (GDM) was investigated using a two-sample Mendelian randomization study based on publicly available statistics from genome-wide association studies (GWAS). The inverse-variance weighted method was employed as the primary analytical approach to examine the association between PCOS, its characteristic indices, and GDM. MR Egger intercept was used to assess pleiotropy, while Q values and their corresponding P values were utilized to evaluate heterogeneity. It is important to note that this study adopts a two-sample MR design where PCOS and its characteristic indices are considered as exposures, while GDM is treated as an outcome. Results The study results indicate that there is no causal relationship between PCOS and GDM (all methods P > 0.05, 95% CI of OR values passed 1). The IVW OR value was 1.007 with a 95% CI of 0.906 to 1.119 and a P value of 0.904. Moreover, the MR Egger Q value was 8.141 with a P value of 0.701, while the IVW Q value was also 8.141 with a P value of 0.774, indicating no significant heterogeneity. Additionally, the MR Egger intercept was 0.0004, which was close to zero with a P value of 0.988, suggesting no pleiotropy. However, the study did find a causal relationship between several other factors such as testosterone, high-density lipoprotein, sex hormone-binding globulin, body mass index, waist-hip ratio, apolipoprotein A-I, number of children, diabetes illnesses of mother, father and siblings, hemoglobin A1c, fasting insulin, fasting blood glucose, years of schooling, and GDM based on the IVW method. Conclusion We observed no association between genetically predicted PCOS and the risk of GDM, implying that PCOS itself does not confer an increased susceptibility to GDM. The presence of other PCOS-related factors such as testosterone, high-density lipoprotein, and sex hormone-binding globulin may elucidate the link between PCOS and GDM. Based on these findings, efforts aimed at preventing GDM in individuals with PCOS should prioritize those exhibiting high-risk features rather than encompassing all women with PCOS.

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.

Role of Beta Cell Function and Insulin Resistance in the Development of Gestational Diabetes Mellitus. Nutrients 2022; 14:nu14122444.

Abstract
Background: Gestational diabetes mellitus (GDM) is a pregnancy complication characterized by second trimester hyperglycemia. Untreated, GDM is related to an increased risk for adverse pregnancy outcomes. Both beta cell dysfunction and insulin resistance underlie impaired glucose tolerance. Understanding the dominant mechanism predisposing to GDM may be important to provide effective treatment in order to improve perinatal outcomes. We hypothesize that insulin resistance rather that beta cell dysfunction predisposes to GDM. Methods: A 75g oral glucose tolerance test (OGTT) was performed on 2112 second-trimester pregnant women to determine the relationship between insulin resistance (HOMA-IR), beta cell function (HOMA-β), and the prevalence of abnormal glucose handling. Results: High insulin resistance raised the risk of GDM (relative risk (RR) 6.1, 95% confidence interval (CI) (4.4–8.5)), as did beta cell dysfunction (RR 3.8, 95% CI (2.7–5.4)). High insulin resistance, but not beta cell function, enhances the necessity for additional glucose lowering medication on top of a low carbohydrate diet in women diagnosed with GDM. Conclusions: Both high insulin resistance and beta cell dysfunction increase the risk of GDM. As increased insulin resistance, rather than beta cell function, is related to an insufficient response to a low carbohydrate diet, we speculate that insulin sensitizers rather than insulin therapy may be the most targeted therapeutic modality in diet-insensitive GDM.

Abstract
OBJECTIVE To correlate the distinct diagnostic criteria of polycystic ovary syndrome (PCOS) with the development of maternal and neonatal complications. DESIGN Systematic review and meta-analysis. SETTING Not applicable. PATIENT(S) Pregnant women with PCOS. INTERVENTION(S) Maternal and neonatal complications were compared among women with PCOS diagnosed with different criteria. MAIN OUTCOME MEASURE(S) The primary outcomes of gestational diabetes mellitus and preeclampsia (PE) were assessed for every diagnostic criterion. RESULT(S) Seventy-nine studies were included. Regarding gestational diabetes, the overall pooled prevalence was 14% (95% confidence interval [CI], 11%-18%; I2, 97%), reaching the highest level when polycystic ovarian morphology on ultrasound and 1 of the remaining 2 Rotterdam criteria (1/2 Rotterdam criteria) were used (18%; 95% CI, 13%-24%; I2, 20%) and the lowest when polycystic morphology on ultrasound and hyperandrogenism were used (3%; 95% CI, 0%-19%; I2, not applicable). Regarding PE, the overall pooled prevalence was 5% (95% CI, 4%-7%; I2, 82%). The highest PE prevalence was reported when the National Institutes of Health criteria were used (14%; 95% CI, 5%-33%; I2, 90%) and the lowest when menstrual irregularities and 1 of the 2 Rotterdam criteria were used (2%; 95% CI, 1%-3%; I2, not applicable). CONCLUSION(S) The prevalence of gestational diabetes mellitus in pregnant women with PCOS does not differ according to the criteria used; however, women diagnosed with PCOS per the National Institutes of Health criteria are at higher risk of PE.

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
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
Polycystic ovarian syndrome (PCOS) is the most common endocrinological disease of reproductive-aged women, with an estimated incidence ranging from 5% to 15%. The clinical manifestations of PCOS are heterogeneous and vary according to the age of the patient. Insulin resistance (IR), hyperandrogenism, and obesity are widely assumed to play a pivotal role in the pathophysiological mechanism of PCOS. As previously stated by many conducted meta-analyses, PCOS can cause a rising risk of pregnancy complications, including maternal, fetal, and neonatal complications. Pregnancy-induced hypertension (PIH), preeclampsia (PE), gestational diabetes mellitus (GDM), spontaneous preterm birth (PTB), and an increased necessity for a cesarean section (CS) are the most documented maternal implications. Regarding fetal outcomes, PCOS has also been correlated with elevated neonatal morbidity, prematurity, fetal growth restriction (FGR), birth weight variations (large for gestational age (LGA) and small for gestational age (SGA), and transfer to the neonatal intensive care unit (NICU). Owing to the variability of the studies performed, the association of PCOS with an elevated risk of adverse pregnancy outcomes is still controversial. This variability is found in the diagnosis and clinical presentations of PCOS, and can be influenced by pre-pregnancy circumstances and therapies as well as particular population and environmental features. The Amsterdam consensus guidelines confirm that obesity and IR can worsen maternal and fetal complications; thus, a closer follow-up should be offered to PCOS women during pregnancy.

Abstract
The purpose of this prospective, population-based cohort study was to evaluate the roles of polycystic ovary syndrome (PCOS), obesity, weight gain, and hyperandrogenemia in the development of hypertensive disorders of pregnancy (HDP) through fertile age both in PCOS and in non-PCOS women. The study population-NFBC1966 (Northern Finland Birth Cohort 1966)-allowed a long-term follow-up of women from age 14 until 46 years who developed HDP (n=408) or did not (n=3373). HDP diagnosis was confirmed by combining hospital discharge records, data from Finnish Medical Birth Registers, and the questionnaire data at age 46. Women with self-reported PCOS (srPCOS; n=279), defined by both oligo-amenorrhea and hirsutism at age 31 or with PCOS diagnosis by age 46, were compared with women without reported PCOS (n=1577). Women with srPCOS had an increased HDP risk (odds ratio, 1.56 [95% CI, 1.03-2.37]), but the association disappeared after adjustment for body mass index. In women with srPCOS and HDP, body mass index increased from age 14 to 46 significantly more than in srPCOS women without HDP (median [interquartile range], 9.82 [6.23-14.6] and 7.21 [4.16-10.5] kg/m2, respectively; P<0.001). Also, in non-PCOS women, the increase was higher in women with (7.54 [5.32-11.62] kg/m2; P<0.001) than without HDP (6.33 [3.90-9.33] kg/m2; P<0.001). Increase in waist circumference between ages 31 and 46 years was associated with HDP but not with PCOS. Hyperandrogenemia at 31 or 46 years did not associate with HDP (1.44 [0.98-2.11]). In conclusion, obesity, especially abdominal obesity, and weight gain from adolescence to age 46, but not srPCOS or hyperandrogenemia, were associated with an increased risk of HDP.

Abstract
Gestational diabetes mellitus (GDM) has become an epidemic and has caused a tremendous healthy and economic burden in China, especially after the "two-child policy" put into effect on October 2015. The prevalence of GDM has continued to increase during the past few decades and is likely to see a further rise in the future. The public health impact of GDM is becoming more apparent in China and it might lead to the development of chronic non-communicable diseases in the long-term for both mothers and their children. Early identification of high-risk individuals could help to take preventive and intervention measures to reduce the risk of GDM and adverse perinatal outcomes. Therefore, a focus on prevention and intervention of GDM in China is of great importance. Lifestyle interventions, including dietary and physical exercise intervention, are effective and first-line preventive strategies for GDM prevention and intervention. The GDM One-day Care Clinic established in 2011, which educates GDM patients on the basic knowledge of GDM, dietary intervention, physical exercise, weight management, and blood glucose self-monitoring methods, sets a good model for group management of GDM and has been implemented throughout the hospitals as well as maternal and child health centers in China. The current review focus on the prevalence, risk factors, as well as prevention and lifestyle intervention of GDM in China for better understanding of the latest epidemiology of GDM in China and help to improve maternal and neonatal pregnancy outcomes and promote long-term health for women with GDM.

Abstract
Polycystic ovary syndrome (PCOS), characterized by hormonal imbalance and ovarian dysfunction, often starts during adolescence. Inconsistent diagnostic criteria, variable provider knowledge, and lack of consensus pose specific challenges for the care of women with PCOS. These factors encourage inaccurate diagnosis with both under and overdiagnosis. This unfavorable diagnostic experience exasperates affected women and limits timely opportunities for intervention to minimize associated comorbidities, especially during the transition from pediatric to adult care. Recognition of these issues in the care of adolescents and women with PCOS inspired the development of the International Evidence-Based PCOS Guidelines, which emphasize the prevention, screening, and treatment of PCOS across the reproductive lifespan. The Guidelines and accompanying meta-analyses focus on three major categories of associated comorbidities: (1) reproductive; (2) metabolic; and (3) psychological. With the exception of infertility, this article considers common manifestations and comorbidities associated with PCOS throughout the lifecycle. Healthy lifestyle interventions with prevention of excess weight gain comprise the primary intervention for all comorbidities. Hence, early identification of girls "at risk" for PCOS and those with PCOS is a priority. Extensive guidelines for provider and patient education aim to decrease the medical, psychosocial, and economic burdens attributable to PCOS and its associated comorbidities.

Abstract
Polycystic ovary syndrome (PCOS) is associated with worsened pregnancy and infant outcomes, higher body mass index (BMI), and longitudinal weight gain. Despite most of the clinical features of PCOS being risk factors for worsened infant outcomes in the general population, their impact on infant outcomes in PCOS is unknown. We aimed to investigate the association of PCOS with infant outcomes considering maternal adiposity, other known risk factors, and potential confounders. The meta-analyses included 42 studies in 7041 women with PCOS and 63 722 women without PCOS. PCOS was associated with higher gestational weight gain (GWG) and with higher preterm birth and large for gestational age and with lower birth weight with this association varying by geographic continent, PCOS phenotypes, and study quality. However, PCOS was associated with none of these outcomes on BMI-matched studies. Gestational diabetes was significantly associated with an increased preterm birth on meta-regression. We report for the first time that GWG is higher in PCOS. Infant outcomes vary by geographic continent and study quality but are similar in BMI-matched women with and without PCOS. This suggests that infant outcomes in PCOS may be related to maternal obesity. These novel findings warrant future studies in PCOS investigating screening and management of infant outcomes with consideration of maternal obesity.

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
The results of studies that assessed the impact of metformin treatments on gestational diabetes mellitus (GDM) in patients with polycystic ovary syndrome (PCOS) are inconclusive. In addition, the impact of time and duration of metformin therapy for an optimum reduction of GDM has not been reported in these studies. This study aimed to summarize current knowledge regarding the effect of metformin-therapy before conception versus throughout pregnancy on the risk of GDM in women with PCOS. PubMed, Scopus, Google Scholar and ScienceDirect databases were searched to identify relevant studies. Both fixed and random effect models were used. Subgroup analyses were performed based on the on the study methodology. The association between the PCOS status and GDM was assessed using the univariate and multiple meta-regression analysis adjusted by the BMI and metformin therapy. Forty-eight of 1397 identified studies were included involving 5711 PCOS patients and 20,296 controls. Regardless of metformin therapy, the prevalence of GDM diagnosed in the second trimester among women with PCOS was significantly higher than healthy controls that was independent of obesity. Including all studies, the increased risk of GDM among women with PCOS, compared to healthy controls, disappeared after the adjustment of metformin-therapy (β = 0.08, 95% CI 0.04, 0.2; p = 0.624). By excluding observational studies as a source of bias, the prevalence of GDM among women with PCOS treated using metformin before conception till the end of pregnancy did not differ from treated just before conception (β = - 0.09, 95% CI - 0.2, 0.02; p = 0.092) or those without metformin therapy (β = - 0.05, 95% CI - 0.07, 0.04; p = 0.301). The results remained unchanged after the subgroup analysis based on the methodology of RCTs and non-RCTs studies. The main body of literature in the current meta-analysis was observational, which may be mixed with some sources of bias. Also, a lack of well-designed and high quality interventional studies means that the findings should be interpreted with cautious. In this respect, decisions regarding the continuation or discontinuation of metformin therapy in women with PCOS are somewhat arbitrary and can be made individually based on the patient's condition given the presence or absence of other GDM risk factors. Additional well-designed RCTs still need for precise recommendation.

Grieger JA, Bianco-Miotto T, Grzeskowiak LE, Leemaqz SY, Poston L, McCowan LM, Kenny LC, Myers JE, Walker JJ, Dekker GA, Roberts CT. Metabolic syndrome in pregnancy and risk for adverse pregnancy outcomes: A prospective cohort of nulliparous women. PLoS Med 2018; 15:e1002710. [PMID: 30513077 PMCID: PMC6279018 DOI: 10.1371/journal.pmed.1002710] [Citation(s) in RCA: 95] [Impact Index Per Article: 15.8] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/23/2017] [Accepted: 11/02/2018] [Indexed: 12/22/2022] Open
Abstract
BACKGROUND Obesity increases the risk for developing gestational diabetes mellitus (GDM) and preeclampsia (PE), which both associate with increased risk for type 2 diabetes mellitus (T2DM) and cardiovascular disease (CVD) in women in later life. In the general population, metabolic syndrome (MetS) associates with T2DM and CVD. The impact of maternal MetS on pregnancy outcomes, in nulliparous pregnant women, has not been investigated. METHODS AND FINDINGS Low-risk, nulliparous women were recruited to the multi-centre, international prospective Screening for Pregnancy Endpoints (SCOPE) cohort between 11 November 2004 and 28 February 2011. Women were assessed for a range of demographic, lifestyle, and metabolic health variables at 15 ± 1 weeks' gestation. MetS was defined according to International Diabetes Federation (IDF) criteria for adults: waist circumference ≥80 cm, along with any 2 of the following: raised trigycerides (≥1.70 mmol/l [≥150 mg/dl]), reduced high-density lipoprotein cholesterol (<1.29 mmol/l [<50 mg/dl]), raised blood pressure (BP) (i.e., systolic BP ≥130 mm Hg or diastolic BP ≥85 mm Hg), or raised plasma glucose (≥5.6 mmol/l). Log-binomial regression analyses were used to examine the risk for each pregnancy outcome (GDM, PE, large for gestational age [LGA], small for gestational age [SGA], and spontaneous preterm birth [sPTB]) with each of the 5 individual components for MetS and as a composite measure (i.e., MetS, as defined by the IDF). The relative risks, adjusted for maternal BMI, age, study centre, ethnicity, socioeconomic index, physical activity, smoking status, depression status, and fetal sex, are reported. A total of 5,530 women were included, and 12.3% (n = 684) had MetS. Women with MetS were at an increased risk for PE by a factor of 1.63 (95% CI 1.23 to 2.15) and for GDM by 3.71 (95% CI 2.42 to 5.67). In absolute terms, for PE, women with MetS had an adjusted excess risk of 2.52% (95% CI 1.51% to 4.11%) and, for GDM, had an adjusted excess risk of 8.66% (95% CI 5.38% to 13.94%). Diagnosis of MetS was not associated with increased risk for LGA, SGA, or sPTB. Increasing BMI in combination with MetS increased the estimated probability for GDM and decreased the probability of an uncomplicated pregnancy. Limitations of this study are that there are several different definitions for MetS in the adult population, and as there are none for pregnancy, we cannot be sure that the IDF criteria are the most appropriate definition for pregnancy. Furthermore, MetS was assessed in the first trimester and may not reflect pre-pregnancy metabolic health status. CONCLUSIONS We did not compare the impact of individual metabolic components with that of MetS as a composite, and therefore cannot conclude that MetS is better at identifying women at risk. However, more than half of the women who had MetS in early pregnancy developed a pregnancy complication compared with just over a third of women who did not have MetS. Furthermore, while increasing BMI increases the probability of GDM, the addition of MetS exacerbates this probability. Further studies are required to determine if individual MetS components act synergistically or independently.

Abstract
BACKGROUND Insulin resistance is common in polycystic ovary syndrome (PCOS). PCOS may be associated with increased risk of gestational diabetes mellitus (GDM). OBJECTIVES To (1) review literature regarding PCOS and hyperglycaemia in pregnancy and (2) present original data from Odense Child Cohort (OCC) regarding GDM in PCOS. METHODS Literature search including original studies from 2000-18. OCC included 2548 pregnant women, 9.5% (n = 241) had PCOS. Fasting plasma glucose was measured in 1519 and 659 oral glucose tolerance tests were performed (with risk factor for GDM, n = 384, without risk factors, n = 275), applying two different GDM criteria. RESULTS 30 studies were eligible using 12 different sets of diagnostic criteria for GDM. Ten studies included n > 50, control group, assessment of GDM and BMI. Results were not uniform, but supported that higher BMI, higher age, Asian ethnicity, and fertility treatment increased the risk of GDM in PCOS. In OCC, women with PCOS and controls had similar prevalences of GDM independent of different sets of criteria for GDM. CONCLUSION PCOS may not be an individual risk factor for GDM. Pregnancies in PCOS are characterized by factors known to increase risk of GDM, especially high BMI and fertility treatment.

Abstract
Although there is a growing body of literature reporting that pregnancies in women with polycystic ovary syndrome (PCOS) are associated with greater complications than those without PCOS, methodological differences across studies make these results difficult to consolidate. This narrative review outlines potential mechanisms involved in adverse pregnancy outcomes in PCOS and the nature of the complications. It covers limitations of current evidence and future research directions. Future research should include prospective studies with phenotypic stratification of PCOS and matching or consideration of specific PCOS manifestations and risk factors specific to each pregnancy complication. This review also emphasizes the importance of following a healthy lifestyle for women with PCOS and of individualized care according to overall risk factors for pregnancy complications.

Abstract
Polycystic ovary syndrome (PCOS) is a heterogenous endocrine disorder with typical symptoms of oligomenorrhoea, hyperandrogenism, hirsutism, obesity, insulin resistance and increased risk of type 2 diabetes mellitus. Extensive evidence indicates that PCOS is a genetic disease and numerous biochemical pathways have been linked with its pathogenesis. A number of genes from these pathways have been investigated, which include those involved with steroid hormone biosynthesis and metabolism, action of gonadotropin and gonadal hormones, folliculogenesis, obesity and energy regulation, insulin secretion and action and many others. In this review, we summarize the historical and recent findings in genetic polymorphisms of PCOS from the relevant publications and outline some genetic polymorphisms that are potentially associated with the risk of PCOS. This information could uncover candidate genes associating with PCOS, which will be valuable for the development of novel diagnostic and treatment platforms for PCOS patients.

Abstract
OBJECTIVE To evaluate the prevalence of adverse pregnancy outcomes in healthy Chinese women and to investigate whether these outcomes could be decreased in patients with polycystic ovary syndrome (PCOS) by ethinylestradiol/cyproterone acetate (EE/CPA) pretreatment. DESIGN Retrospective study. SETTING Medical university. PATIENT(S) Six thousand healthy women (group A) were selected from 24,566 pregnant women by randomized sampling. Four hundred forty-eight patients with PCOS without EE/CPA pretreatment were assigned to group B, and 222 patients with PCOS with 3 months of pretreatment to group C. All patients with PCOS had biochemical and/or clinical hyperandrogenism and conceived within 3 monthly ovulation inductions using clomiphene. INTERVENTION(S) None. MAIN OUTCOME MEASURE(S) Gestational diabetes mellitus (GDM), pregnancy-induced hypertension (PIH), premature delivery (PD), and neonatal birth weight. RESULT(S) The prevalence of GDM, PIH, and PD was higher in group B than in groups A and C (A vs. B vs. C: GDM, 21.2% vs. 35.0% vs. 22.5%; PIH, 6.5% vs. 14.1% vs. 7.7%; PD, 5.4% vs. 8.6% vs. 6.8%). No significant difference was found in neonatal birth weight. After adjusting for age, pregestational body mass index, education level, and employment status, PCOS without pretreatment increased the risk of GDM (adjusted odds ratio [aOR] = 1.666; 95% confidence interval [CI], 1.340-2.072), PIH (aOR = 1.487; 95% CI, 1.093-2.023), and PD (aOR = 1.522; 95% CI 1.051-2.205), compared with healthy women. No increased risk was found in group C. CONCLUSION(S) In our highly selected study population, patients with PCOS are more likely to develop GDM, PIH, and PD. Pretreatment with EE/CPA was associated with a lower risk of GDM, PIH, and PD.

Abstract
This retrospective, cohort study examined the association between maternal pre-pregnancy body mass index (BMI), independent of glucose tolerance and adverse pregnancy outcomes in women with polycystic ovary syndrome (PCOS), for which there are few previous studies. Medical records from 2012 to 2015 at Guangzhou Women and Children's Medical Center, China were reviewed for women previously diagnosed with PCOS with normal 2-h 75-g oral glucose tolerance test (OGTT) results (n = 1249). The separate and joint effects of maternal BMI and glucose levels on pregnancy outcomes were assessed. Maternal pre-pregnancy BMI was associated with hypertensive disorders of pregnancy (HDP) (OR: 1.22, 95% CI: 1.02-1.45), preterm birth (OR: 1.49, 95% CI: 1.08-2.17), and large for gestational age (LGA) (OR: 1.69, 95% CI: 1.16-2.20). Elevated fasting glucose and maternal pre-pregnancy BMI were jointly associated with increased risks of HDP, preterm birth, and LGA. Therefore, among women with PCOS and normal glucose tolerance, maternal pre-pregnancy BMI is an independent risk factor of adverse pregnancy outcomes.

Abstract
BACKGROUND Polycystic ovary syndrome (PCOS) is inconsistently associated with increased risk of adverse pregnancy outcomes. The purpose of this meta-analysis was to summarize the evidence regarding the strength of the association between pregnancy in women with PCOS and pregnancy complications. METHODS We systematically searched PubMed, EmBase, and the Cochrane Library to identify observational studies up to January 2016. The primary focus was pregnancy outcomes, including gestational diabetes mellitus (GDM), preeclampsia, pregnancy-induced hypertension (PIH), preterm delivery, cesarean delivery, oligohydramnios, and polyhydramnios. Effect estimates were pooled using the random-effects model. The analysis was further stratified by factors that could affect these associations. RESULTS We included 40 observational studies that reported data on a total of 17,816 pregnancies with PCOS and 123,756 pregnancies without PCOS. Overall, PCOS in pregnancy was associated with greater risk of GDM, preeclampsia, PIH, preterm delivery, cesarean delivery, miscarriage, hypoglycemia, and perinatal death. However, PCOS in pregnancy had little or no effect on oligohydramnios, polyhydramnios, large-for-gestational age (LGA), small-for-gestational-age (SGA), fetal growth restriction (FGR), preterm premature membrane rupture, fasting blood glucose (FBG), high-density lipoprotein (HDL), low-density lipoprotein (LDL), triglyceride, total cholesterol, congenital malformation, macrosomia, and respiratory distress syndrome. Subgroup analysis suggested that these associations might be influenced by study design and pre-BMI. CONCLUSION PCOS in pregnancy is associated with a significantly increased risk of adverse pregnancy, fetal, and neonatal outcomes.

Abstract
PURPOSE Gestational diabetes mellitus (GDM) continues to be a significant health disorder triggering harmful complications in pregnant women and fetuses. Our knowledge of GDM epidemiology in Yemen is largely based on very limited data. The aim of this study was, therefore, to determine the prevalence and risk factors of GDM among pregnant women in Dhamar governorate, Yemen. PATIENTS AND METHODS A total of 311 subjects were randomly selected for this cross sectional survey. Health history data and blood samples were collected using a pretested questionnaire. To determine the prevalence of GDM, the fasting and random blood glucose techniques were applied according to the recommendations of the American Diabetes Association, using alternative methods that are more convenient to the targeted population. Poisson's regression model incorporating robust sandwich variance was utilized to assess the association of potential risk factors in developing GDM. RESULTS The prevalence of GDM was found to be 5.1% among the study population. Multivariate analysis confirmed age ≥30 years, previous GDM, family history of diabetes, and history of polycystic ovary syndrome as independent risk factors for GDM prevalence. However, body mass index ≥30 kg/m(2) and previous macrosomic baby were found to be dependent risk factors. CONCLUSION This study reports new epidemiological information about the prevalence and risk factors of GDM in Yemen. Introduction of proper maternal and neonatal medical care and health education are important in order to save the mother and the baby.

Abstract
Gestational exposure to excess T leads to intrauterine growth restriction, low birth weight, and adult metabolic/reproductive disorders in female sheep. We hypothesized that as early mediators of such disruptions, gestational T disrupts steroidal and metabolic homeostasis in both the mother and fetus by both androgenic and metabolic pathways. Maternal blood samples were measured weekly for levels of insulin, glucose, and progesterone from four groups of animals: control; gestational T (twice weekly im injections of 100 mg of T propionate from d 30 to d 90 of gestation); T plus an androgen antagonist, flutamide (15 mg/kg·d oral; T-Flutamide); and T plus the insulin sensitizer, rosiglitazone (0.11 mg/kg·d oral; T-Rosi) (n = 10-12/group). On day 90 of gestation, maternal and umbilical cord samples were collected after a 48-hour fast from a subset (n = 6/group) for the measurement of steroids, free fatty acids, amino acids, and acylcarnitines. Gestational T decreased maternal progesterone levels by 36.5% (P < .05), which was prevented by flutamide showing direct androgenic mediation. Gestational T also augmented maternal insulin levels and decreased medium chained acylcarnitines, suggesting increased mitochondrial fatty acid oxidation. These changes were prevented by rosiglitazone, suggesting alterations in maternal fuel use. Gestational T-induced increases in fetal estradiol were not prevented by either cotreatment. Gestational T disrupted associations of steroids with metabolites and progesterone with acylcarnitines, which was prevented either by androgen antagonist or insulin sensitizer cotreatment. These findings suggest a future combination of these treatments might be required to prevent alteration in maternal/fetal steroidal and metabolic milieu(s).
