Abstract Context Polycystic ovary syndrome (PCOS) is the most common endocrine disorder of women in reproductive age and is associated with reproductive, endocrine, metabolic, cardiovascular, and psychological outcomes. All these disorders are thought to be affected by central mechanisms which could be a major contributor in pathogenesis of PCOS. Evidence Acquisition This mini-review discusses the relevance of central nervous system imaging modalities in understanding the neuroendocrine origins of PCOS as well as their relevance to understanding its comorbidities. Evidence Synthesis Current data suggest that central nervous system plays a key role in development of PCOS. Decreased global and regional brain volumes and altered white matter microstructure in women with PCOS is shown by structural imaging modalities. Functional studies show diminished reward response in corticolimbic areas, brain glucose hypometabolism, and greater opioid receptor availability in reward-related regions in insulin-resistant patients with PCOS. These structural and functional disturbances are associated with nonhomeostatic eating, diminished appetitive responses, as well as cognitive dysfunction and mood disorders in women with PCOS. Conclusion Structural and functional brain imaging is an emerging modality in understanding pathophysiology of metabolic disorders such as diabetes and obesity as well as PCOS. Neuroimaging can help researchers and clinicians for better understanding the pathophysiology of PCOS and related comorbidities as well as better phenotyping PCOS.

New Evidence

: Polycystic ovary syndrome (PCOS) is a condition that affects about 15% of women of reproductive age and is correlated with infertility, insulin resistance, and obesity. The etiology of PCOS is multifactorial and genetic, endocrine, and metabolic causes were involved. New evidence suggests a link between microorganisms residing in the digestive tracts of humans and the development of PCOS. Moreover, an imbalance in the gut microbial community could be a possible factor for the onset of insulin resistance and obesity. Hyperandrogenism, a key feature of PCOS, could also play a critical role in shaping the microbiome community. Probiotics could modify the gut microbiota and serve as a potential treatment for PCOS. Here we disclose the association between PCOS and intestinal microbiota and the possible role of probiotics as a new treatment approach.

Ovary Syndrome

Abstract Context Polycystic ovary syndrome (PCOS) is a common endocrine condition affecting 8% to 13% of women across the lifespan. PCOS affects reproductive, metabolic, and mental health, generating a considerable health burden. Advances in treatment of women with PCOS has been hampered by evolving diagnostic criteria and poor recognition by clinicians. This has resulted in limited clinical and basic research. In this study, we provide insights into the current and future research on the metabolic features of PCOS, specifically as they relate to PCOS-specific insulin resistance (IR), that may affect the most metabolically active tissue, skeletal muscle. Current Knowledge PCOS is a highly heritable condition, yet it is phenotypically heterogeneous in both reproductive and metabolic features. Human studies thus far have not identified molecular mechanisms of PCOS-specific IR in skeletal muscle. However, recent research has provided new insights that implicate energy-sensing pathways regulated via epigenomic and resultant transcriptomic changes. Animal models, while in existence, have been underused in exploring molecular mechanisms of IR in PCOS and specifically in skeletal muscle. Future Directions Based on the latest evidence synthesis and technologies, researchers exploring molecular mechanisms of IR in PCOS, specifically in muscle, will likely need to generate new hypothesis to be tested in human and animal studies. Conclusion Investigations to elucidate the molecular mechanisms driving IR in PCOS are in their early stages, yet remarkable advances have been made in skeletal muscle. Overall, investigations have thus far created more questions than answers, which provide new opportunities to study complex endocrine conditions.

Abstract Context Polycystic ovary syndrome (PCOS) is the most common endocrine disorder of reproductive-aged women, affecting approximately 5-20% of women of reproductive age. A previous estimate noted that the economic burden of PCOS approximates $3.7 billion annually in 2020 USD when considering only the costs of the initial diagnosis and of reproductive endocrine morbidities, not considering the costs of pregnancy-related and long-term morbidities. Objective To estimate the excess prevalence and economic burden of pregnancy-related and long-term health morbidities attributable to PCOS. Data Sources PubMed, EmBase and Cochrane Library. Study Selection Studies in which the diagnosis of PCOS was consistent with the Rotterdam, National Institutes of Health (NIH), or Androgen Excess & PCOS (AE-PCOS) Society criteria, or that used electronic medical record diagnosis codes, or diagnosis based on histopathologic sampling were eligible for inclusion. Studies that included an outcome of interest and a control group of non-PCOS patients who were matched or controlled for body mass index (BMI) were included. Data Extraction Two investigators working independently extracted data on study characteristics and outcomes. Data Synthesis Data was pooled using random-effects meta-analysis. The I 2statistic was used to assess inter-study heterogeneity. The quality of selected studies was assessed using the Newcastle-Ottawa Scale. Results The additional total healthcare-related economic burden due to pregnancy-related and long-term morbidities associated with PCOS in the United States is estimated to be $4.3 billion annually in 2020 USD. Conclusions Together with our prior analysis, the economic burden of PCOS is estimated at $8 billion annually in 2020 USD.

Treatment Of Obesity

Polycystic ovary syndrome (PCOS) is a common disorder affecting women of reproductive age and it is associated with increased cardiovascular risk. Obesity plays an important role in the pathogenesis of PCOS, and the majority of patients with PCOS are obese. Over the last 20 years, the prevalence of obesity has dramatically increased, with probable associated increase in PCOS. Weight reduction plays an integral part in the management of women with PCOS. In this paper, current available weight reduction therapies in the management of PCOS are discussed.

Vitamin D3 Deficiency

Background: Polycystic ovary syndrome (PCOS) is enigma faced by young females since the onset of urbanization. As on day, PCOS is the most common endocrine disorder in the women of reproductive age affecting 4-10%. This study done to measure serum vitamin D3 levels of PCOS patients and to identify its association with factors associated with various symptoms and signs in PCOS.Methods: Institutional based prospective observational study conducted on 70 patients of PCOS, both suspected and already diagnosed, attending gynecology OPD of Department of obstetrics and gynecology of NSCB Medical College Jabalpur from 1 March 2015 to 31 August 2016. Diagnosis of PCOS was made by Rotterdam 2003 criteria. A detailed assessment was done and preformed proforma was filled. Serum Vitamin D3 levels were estimated by standard lab technique ‘Liquid Chromatography Tandem Mass Spectrometry’ and categorized into vitamin D3 sufficient >30ng/dl, insufficient 20-29ng/dl and deficient <20ng/dl. Categorical data was coded numerically before the analysis. For comparison of frequency distribution chi square test or fisher’s exact test were applied as appropriate.Results: Prevalence of Vitamin D3 deficiency in patients of PCOS was found to be 84.3%.Conclusions: The present study concludes that there is correlation between vitamin D3 and PCOS, screening and correction of vitamin D3 deficiency may prevent PCOS and its manifestations. Hence, it is speculated that improvement of vitamin D3 levels at a younger age can contribute to prevention of PCOS.
