Filter by:Polycystic Ovary Syndrome (PCOS) affects 10% of all women, and it usually co-exists with high levels of male pattern hormones (also termed androgens). Women with PCOS are at increased risk of metabolic complications such as diabetes, non-alcoholic fatty liver disease, high blood pressure and heart disease. However, very little is understood about how androgen excess results in increased metabolic complications observed in women with PCOS. The main aims of the REFUEL PCOS study are to compare markers of energy metabolism in women with PCOS to those without PCOS. This will allow the investigators to better understand metabolic risk by examining the relationship between androgen excess and energy metabolism. Skeletal muscle is an important site of energy metabolism, and emerging theories are that androgen excess impairs skeletal muscle energy balance and increases the risk of complications. Based on these emerging theories, the investigators want to investigate the effects of androgens on muscle energy metabolism. The investigators will also examine whether certain blood and urine result patterns can help identify differences in muscles energy metabolism and which women are at the highest risk of metabolic complications. This research will give insight into the metabolic risk associated with PCOS and treat and, where possible, prevent the development of metabolic disease in affected women.
The Study aims to determine the proposed positive influence of Sitagliptin in manipulating hormonal , metabolic and inflammatory parameters in the treatment of Polycystic ovary syndrome and subsequent infertility
The goal of this study is to assess response to kisspeptin as well as the baseline patterns of luteinizing hormone (LH) secretion in individuals with polycystic ovarian syndrome (PCOS).
Chronic inflammation is the core of Polycystic ovary syndrome (PCOS), and obesity and overweight further exacerbate the level of inflammation in the peripheral circulation and ovarian tissue in PCOS patients. Metformin is a classic endocrine drug for the treatment of PCOS, but its clinical response rate is only about 40%. Our previous published study (Diabetes Obes Metab, 2022) observed that the new hypoglycemic drug SGLT-2 inhibitor can significantly improve the clinical symptoms of patients with insulin resistance PCOS, and the clinical efficacy is not inferior to metformin, but its specific mechanism of action is not clear. Recent studies have shown that SGLT-2 significantly attenuates the activation of the Nod-like receptor protein 3 (NLRP3) inflammasomes and the secretion of IL-1β in patients with type 2 diabetes mellitus at high risk of cardiovascular disease. Based on the above research background, this project will combine clinical research and mechanism exploration to solve the following two problems: 1. whether SGLT2 inhibitor can further improve the clinical efficacy of PCOS patients compared to metformin; 2. mechanistic studies further clarify whether SGLT2 inhibitors improve inflammatory symptoms by modulating NLRP3 inflammosomes in the treatment of polycystic ovary syndrome;
Polycystic Ovary Syndrome (PCOS) is a complex endocrine disorder characterized by hyperandrogenism, insulin resistance, and ovulatory dysfunction. One of the diagnostic criteria for PCOS is the presence of polycystic ovaries, which are enlarged ovaries with multiple follicles on ultrasound. However, the mechanisms that lead to the development of polycystic ovaries in PCOS are not completely understood. One potential area of investigation is the role of ovarian innervation in the pathophysiology of PCOS. Therefore, the aim of this study is to evaluate the ovarian innervation in PCOS patients through ovarian biopsy sampling.
The aim of this study is to compare the hormonal, metabolic and clinical effects of metformin and liraglutide in infertile women with PCOs.
Polycystic ovary syndrome (PCOS) is the most common endocrine disorder in women of reproductive age and one of the leading causes of infertility. PCOS and obesity affect up to 12.5% - 48.3% Asian women, increase incidence of impaired glucose tolerance, type 2 diabetes and aggravate insulin resistance, cause ovulatory dysfunction and menstrual disorders, and negatively impact outcomes of Assited Reproductive Technology (ART), with higher miscarriage rate when receiving ART. Weight loss decrease insulin resistance and hyperandrogenism, improve ovulation rate and menstrual cycle, significantly higher conception and live birth rates. Weight loss prior to IVF procedures has been associated with significantly improved pregnancy rates (PR) and live birth rates. Furthermore, a decreased number of IVF cycles required to achieve a pregnancy has also been reported after weight loss interventions. Based on the principles of fetal programming, improving a lifestyle before conception might lead to improved longterm health of the offspring. Studies on the effect of anti-obesity medication combined with lifestyle changes on body weight and composition and metabolic - endocrine parameters and pregnancy rate in obese women diagnosed with PCOS are lacking. There is a growing need to develop pharmacologic interventions to improve metabolic function in women with polycystic ovary syndrome (PCOS).
The study aims to investigate the relationship between fasting insulin and Homeostatic Model Assessment of Insulin Resistance (HOMA-IR) across various demographic factors, including age, sex, race/ethnicity, BMI, and polycystic ovary syndrome (PCOS) diagnosis. By analyzing these variables, the study seeks to identify potential variations in insulin levels, which could provide valuable insights into the impact of different factors on metabolic health and the development of insulin-related conditions.
According to World Health Organization (WHO), in 2010, Polycystic Ovarian Syndrome (PCOS) affected approximately 116 million women worldwide (3.4% of the population). It has been considered one of the most common causes of female infertility and the most common endocrine disorder. The standard diagnosis for the syndrome dates back to international conferences organized by the National Institutes of Health (NIH) in 1990 and the Rotterdam European Society of Human Reproduction and Embryology/ American Society for Reproductive Medicine (ESHRE/ASRM) sponsored PCOS consensus workshop group in 2003 and 2004. Clinical manifestations of the disease may include menstrual irregularities, amenorrhea, ovulation-related infertility, polycystic ovaries, and signs of androgen excess such as acne and hirsutism. This condition may also lead to chronic diseases such as obesity, type 2 diabetes (T2D), dyslipidaemia, and cardiovascular events. Despite the increasing knowledge concerning PCOS, the global picture of the disorder is deficient in a number of geographic regions. Understanding the global prevalence will help to better assess the public health and economic implications of PCOS in Trinidad, allow for improved screening methods, help elucidate the underlying factors and foster improved understanding of the molecular mechanisms in improving the evolutionary process.
The Quantum Menstrual Health Monitoring Study will measure four key reproductive hormones in the urine to characterize patterns that predict and confirm ovulation, referenced to serum hormones and the gold-standard of the ultrasound day of ovulation in participants with regular cycles. These normal cycles will provide a reference for comparison to irregular cycles in polycystic ovarian syndrome (PCOS) and athletes. Clinical signs in the menstrual cycle (e.g. menstrual bleeding, temperature) as well as vital sign and sleep patterns will also be referenced to hormonal changes.
