Polycystic ovary syndrome (PCOS) is characterized by the association of androgen excess with chronic oligoovulation and/or polycystic ovarian morphology, yet metabolic disorders and classic and nonclassic cardiovascular risk factors cluster in these women from very early in life. This chapter focuses on the mechanisms underlying the association of PCOS with metabolic dysfunction, focusing on the role of androgen excess on the development of visceral adiposity and adipose tissue dysfunction.

The prevalence of PCOS was investigated in many studies in different continents. However, there is no established prevalence of PCOS for distinct ethnic groups. In the current analysis, we conducted searches in PubMed, The Cochrane Library, EMBASE, CINAHL up to Jan. 2017 to identify studies reporting prevalence of PCOS in the general female population. Forty-two studies were identified, with 13 eligible for evidence synthesis. The prevalence among different ethnicity was estimated using random effect modelling...

PURPOSE: To determine whether ovarian morphology imaged using transabdominal ultrasonography reflects clinical and metabolic features in adolescents with polycystic ovary syndrome (PCOS). METHODS: A retrospective pilot study was conducted in 33 adolescents (12-18 years) with PCOS as defined by hyperandrogenism and irregular cycles. Adolescents underwent the following assessments at a random time during the menstrual cycle: transabdominal ultrasonography, physical examination (height, weight, and systolic and diastolic blood pressure), fasting hormonal tests (free, percent free, and total testosterone, androstenedione, follicle stimulating hormone, luteinizing hormone), and metabolic tests (including an oral glucose tolerance test, fasting and 2-hour insulin and glucose, homeostatic model assessment of insulin resistance, and whole-body insulin sensitivity index)...

There is growing interest in exploring circulating (plasma/serum) irisin in polycystic ovary syndrome (PCOS) patients. This meta-analysis aimed to summarize the evidence assessing circulating irisin changes in this population. A systematic search was conducted in three databases: PubMed, Cochrane Library and Web of Science, for studies reporting irisin in PCOS patients compared with healthy controls or stratified by body mass index (BMI), or assessing irisin response to hyperinsulinemia. Effect sizes (Cohen's d with 95% confidence intervals [CI]) were calculated using random-effects models...

Sebastião Freitas de Medeiros
BACKGROUND: Polycystic ovary syndrome (PCOS) is a complex condition with high risk for dyslipidemia, dysglycemia, venous thromboembolism, cardiovascular disease and metabolic syndrome. Because the combined oral contraceptive (COC) use has also been associated with impaired fasting glucose, insulin resistance and increased risk of thromboembolism disease, it is rationale to think that the combination of oral contraceptive and PCOS could make it worse or increase the risks. OBJECTIVE: To examine the current data regarding potential additional risks and benefits of contraceptive use, highlights the major gap in knowledge for designing future studies and, when possible, suggests an adequate COC formulation for a determined PCOS phenotype...

Background: Hirsutism is frequently expressed in women affected by polycystic ovary syndrome (PCOS). The efficacy of oral contraceptive pill (OC) plus anti-androgens in the treatment of its severe expression is controversial due to the lack of randomized double-blind long-term studies. Aim: The primary outcome was the reduction of hirsutism in PCOS women objectively measured by videodermoscopy (VD) on the androgen-sensitive skin areas assessed by the modified Ferriman&Gallwey (mF&G) total score, after 12 months of therapy with OC+Bicalutamide (BC) versus OC plus placebo (P)...

Large childhood body size has been consistently shown to be associated with decreased breast cancer risk. However, it is important to consider the effects of a large childhood body size on other adult diseases. It is not clear if the associations between childhood body size and adult diseases will persist if they later attain healthy weight. The associations between body size at age 7 and 17 adverse outcomes in adulthood were examined using Cox models in a Swedish study of 65,057 women. Large body size at age 7, when compared to small body size, was associated with decreased risk for breast cancer (HR [95% CI]: 0...

Studies indicate that Polycystic Ovarian Syndrome (PCOS) features (e.g. insulin instability, food cravings, overproduction of androgens and menstrual irregularities) associate with increased appetite, impaired impulse control and feelings of body dissatisfaction. Counter intuitively, binge eating behaviors have been shown to reinforce PCOS symptomatology, precipitating concurrently body dissatisfaction, weight gain, insulin instability and overproduction of androgens. The present systematic literature review aspires to investigate the relationship between binge eating, in the broader context of eating disorder behaviors, and Polycystic Ovarian Syndrome (PCOS), taking into account shared characteristics between EDs (Eating Disorders) and PCOS...

Glucagon, produced by islet α cells, functions to increase blood glucose. Abnormal glucose levels are often seen in cystic fibrosis (CF), a systematic disease caused by mutations of the CF transmembrane conductance regulator (CFTR), and in polycystic ovarian syndrome (PCOS), an endocrine disorder featured with hyperandrogenism affecting 5-10% women of reproductive age. Here, we explored the role of CFTR in glucagon production in α cells and its possible contribution to glucagon disturbance in CF and PCOS...
