Abstract
Gestational diabetes mellitus (GDM) is a common metabolic disorder that often develops during pregnancy, characterized by glucose intolerance and insulin resistance (IR). To ensure the well-being of both the mother and the fetus, the body undergoes multiple metabolic and immunological changes that result in peripheral IR and, under certain hereditary or acquired abnormalities, GDM in predisposed women. The adverse short- and long-term effects of GDM impact both the mother and the fetus. Nutrition seems to play an important role to prevent GDM or improve its evolution. An emphasis has been given to the proportion of carbohydrates (CHO) relative to protein and lipids, as well as dietary patterns, in GDM. The effects of CHO on postprandial glucose concentrations are reflected in the glycemic index (GI) and glycemic load (GL). Diets rich in GI and GL may induce or exacerbate IR, whereas diets low in GI and GL appear to enhance insulin sensitivity and improve glycemic control. These positive outcomes may be attributed to direct interactions with insulin and glucose homeostasis or indirect effects through improved body composition and weight management. This comprehensive narrative review aims to explore the significance of nutrition, with a focus on the critical evaluation of GI and GL in the dietary management of women with GDM.

Abstract
Polycystic ovary syndrome is a common endocrine disorder characterized by hormonal imbalances and various metabolic abnormalities linked to insulin resistance via a vicious cycle. Genetic and environmental factors underlie its pathogenesis and evolution. Nutrition, in terms of nutrient composition, dietary patterns, endocrine-disrupting chemicals, and food processing and preparation, has gained significant attention in the pathogenesis and the therapeutic approach of polycystic ovary syndrome. Carbohydrate intake seems to be a critical point in the diet assignment. Glycemic index and glycemic load constitute indexes of the impacts of dietary carbohydrates on postprandial glucose levels. Numerous studies have indicated that a high glycemic index and glycemic load diet may exacerbate insulin resistance, a key feature of the syndrome, and offer a risk for its development and its complications. Conversely, low-glycemic index and low-glycemic load diets seem to improve insulin sensitivity, regulate menstrual cycles, and mitigate the risk of comorbidities associated with polycystic ovary syndrome, such as obesity, alterations in body composition, type 2 diabetes, cardiovascular disease, and quality of life. This comprehensive review aims to explore the relevance of nutrition and more specifically, the association of glycemic index and glycemic load with the various aspects of polycystic ovary syndrome, as well as to assess the potential benefits of manipulating those indexes in the dietary approach for the syndrome.

Abstract
OBJECTIVE To better characterize the metabolic alterations in various phenotypes of polycystic ovary syndrome (PCOS) in a large homogeneous (Sicilian) Mediterranean population with a low prevalence of obesity. DESIGN Retrospective study. PATIENTS A total of 1215 consecutively evaluated women with PCOS divided into four Rotterdam phenotypes (A, B, C and D) and in 108 matched ovulatory, nonhyperandrogenic women. MEASUREMENTS BMI, fasting glucose, total cholesterol, HDL cholesterol, triglycerides, LDL cholesterol and an oral glucose tolerance test. RESULTS The overall prevalence of obesity was 31%, metabolic syndrome 6.6%, diabetes 2.1%, altered glucose metabolism 13.1%, and abnormal lipid profile 60%. Phenotype B had the highest prevalence of obesity, metabolic syndrome, altered glucose metabolism and lipid abnormalities compared to other PCOS phenotypes and controls. Phenotype A was more obese and more women had metabolic syndrome compared to phenotypes C and D but phenotype C had a similar prevalence of altered glucose metabolism and lipid abnormalities compared to phenotype A which had a higher BMI. These metabolic abnormalities in A and C were higher compared to phenotype D and controls. Multivariate analysis showed that BMI predicts only abnormalities in fasting glucose and triglycerides, while there was no association with androgens. CONCLUSIONS In Mediterranean women with PCOS from Sicily with a lower prevalence of obesity, the prevalence of diabetes, altered glucose metabolism and metabolic syndrome were much lower than reported in US studies. Phenotype B was the most metabolically affected phenotype, followed by phenotype A. Phenotype C had an intermediate disorder but with a high prevalence of altered glucose metabolism and lipid alterations. Only the normoandrogenic phenotype D had no metabolic abnormalities.

Abstract
BACKGROUND/OBJECTIVES The aim of the study was to compare the effect of two-meal patterns (three vs six meals per day) on glucose and insulin levels in women with polycystic ovary syndrome (PCOS). SUBJECTS/METHODS In a randomised, crossover, 24-week study, 40 women with PCOS, aged 27±6 years, body mass index 27±6 kg/m(2), followed a weight maintenance diet (% carbohydrates:protein:fat, 40:25:35), consumed either as a three- or a six-meal pattern, with each intervention lasting for 12 weeks. Anthropometric measurements, diet compliance and subjective hunger, satiety and desire to eat were assessed biweekly. All women underwent an oral glucose tolerance test (OGTT) with 75 g glucose for measurement of plasma glucose and insulin at the beginning and end of each intervention. HaemoglobinA1c (HbA1c), blood lipids and hepatic enzymes were measured at the beginning and end of each intervention. RESULTS Body weight remained stable throughout the study. Six meals decreased significantly fasting insulin (P=0.014) and post-OGTT insulin sensitivity (Matsuda index, P=0.039) vs three meals. After incorporation of individual changes over time, with adjustment for potential confounders, the only variable that remained significant was the Matsuda index, which was then used in multivariate analysis and general linear models. Six meals improved post-OGTT insulin sensitivity independently of age and body weight vs three meals (P=0.012). No significant differences were found between six and three meals for glucose, HbA1c, blood lipids, hepatic enzymes, subjective desire to eat and satiety. CONCLUSIONS Six meals had a more favourable effect on post-OGTT insulin sensitivity in women with PCOS compared with isocaloric three meals.

Abstract
Women with polycystic ovary syndrome (PCOS) are often characterized by adiposity and insulin resistance (IR). Recent studies in patients with obesity and diabetes mellitus type 2 (DMt2) indicate that adiponectin and resistin may play a role in the pathophysiology of IR. The aim of this study was to identify a possible correlation between the plasma levels of adiponectin and resistin and IR in patients with PCOS. Thirty-one women of reproductive age were enrolled in this prospective study after being diagnosed with PCOS and IR according to Rotterdam and American Diabetes Association (ADA) criteria, respectively. Every patient was treated with a daily dose of 1275 mg metformin for 6 months. Adiponectin, resistin, and the primary hormonal and metabolic parameters of the syndrome were evaluated at entry and endpoint of treatment. Adiponectin plasma levels were reduced after metformin treatment, but resistin levels were not significantly affected. Our study suggests that circulating levels of adiponectin should be evaluated with skepticism in patients with PCOS. The adipokine's role in the manifestation of IR in PCOS remains unclear and needs further investigation.

Abstract
Women with polycystic ovary syndrome (PCOS), the most common endocrine disorder among women of reproductive age, exhibit an adverse cardiovascular risk profile characteristic of the cardiometabolic syndrome. These women, compared with age- and body mass index-matched women without PCOS, appear to present a higher risk of insulin resistance, glucose intolerance, and dyslipidemia, and possibly a higher rate of type 2 diabetes mellitus and cardiovascular disease. However, despite the presence of cardiovascular risk factors and increased surrogate markers of cardiovascular disease, it is unclear whether they have accelerated atherosclerosis and greater mortality, the latter mainly because of a lack of endpoint studies. This article addresses, summarizes, and discusses salient data from the existing literature, including gaps and uncertainties, aspects, and mechanisms related to the spectrum of adverse cardiometabolic profile factors in women with PCOS.

Abstract
The polycystic ovary syndrome (PCOS), the most common hyperandrogenic disorder affecting 4-7% of women, is often associated with metabolic alterations, chiefly insulin resistance and obesity. Based on available scientific evidence, PCOS should be regarded as an independent risk for the development of glucose intolerance states. This short review summarizes the available literature on the prevalence and incidence of impaired glucose tolerance and Type 2 diabetes in this disorder. In addition, some insights on potential factors responsible for individual susceptibility are discussed. Targeted intervention studies focused on prevention and treatment of glucose intolerance states in PCOS are warranted.

Abstract
AIM In the current study, we aimed to investigate whether serum orexin-A (OXA) levels are different in polycystic ovary syndrome (PCOS) subjects. MATERIALS AND METHODS Thirty-six women with PCOS and 40 healthy, age and body mass index-matched controls were included in the prospective cross-sectional study. All subjects underwent venous blood draws during the early follicular phase after overnight fasting. Serum OXA levels were measured with an enzyme immunoassay (EIA). The relationships between the serum OXA levels and the anthropometric and metabolic parameters were also assessed. RESULTS The serum OXA levels were lower in the women with PCOS compared to the control group. The serum OXA levels were correlated negatively with systolic blood pressure, the Ferriman-Gallway score and LH and free testosterone levels. CONCLUSION Our results indicate that serum OXA levels decrease in the serum of women with PCOS.
