MicroRNAs as Biomarkers for Metabolic Disorders in Polycystic Ovary Syndrome (PCOS): A Review.

Polycystic ovary syndrome (PCOS) is associated with several mild metabolic disorders, including insulin resistance (IR), obesity, and dyslipidemia, as well as with some more severe ones, including type 2 diabetes mellitus, non-alcoholic fatty liver disease (NAFLD), and cardiovascular disease. Clinically, mild metabolic complications of PCOS such as IR or lipid metabolism disorders are the predictors of these more severe ones. So far, there is no reliable single marker that enables defining metabolic risk in patients with PCOS.

Obesity and Polycystic Ovary Syndrome.

The core pathophysiology of polycystic ovary syndrome involves an overproduction of androgens primarily originating from ovarian thecal cells. Two major external triggers promote androgen overproduction in the ovaries: the increased secretion of luteinizing hormone, a consequence of aberrant hypothalamic gonadotropin-releasing hormone secretion dynamics, and compensatory hyperinsulinemia resulting from insulin resistance. Obesity interacts with polycystic ovary syndrome in multiple ways, but a major role of obesity in its pathophysiology is the exacerbation of insulin resistance.

The rising prevalence of metabolic diseases is a significant global health concern. Beyond lifestyle management, targeting key molecules involved in metabolic regulation is essential. C1q/TNF-related protein 6 (CTRP6) is notably associated with glucose and lipid metabolism, with numerous studies highlighting its regulatory functions in metabolic diseases.

Is vitamin D deficiency a more frequent finding in hirsutism or not?

Evidence shows that vitamin D (Vit D) insufficiency is associated with some hormonal disorders. Hirsutism is a prevalent hormonal condition, which is usually associated with excess of androgenic hormones. Disturbance of Vit D level affects the regulation of these hormones and may be associated with hirsutism.

Pretreatment with oral contraceptive pills in women with PCOS scheduled for IVF: a randomized clinical trial.

Study Question: What is the effect of pretreatment with oral contraceptive pills (OCPs) on oocyte and embryo quality and pregnancy rates in women with polycystic ovary syndrome (PCOS) scheduled for IVF/ICSI cycles?

Summary Answer: In women with PCOS who underwent a first or second IVF/ICSI cycle with a GnRH antagonist protocol and were randomized to start ovarian stimulation immediately, the quality of cleavage-stage embryos was non-inferior to pretreatment with OCP.

What Is Known Already: PCOS in Asian populations is characterized by high levels of circulating LH in the early follicular phase. Previous studies indicated that inappropriately high LH levels might affect oocyte maturation and fertilization rates, and impaired embryo quality, consequently resulting in higher rates of impaired pregnancy and miscarriage in women with PCOS.

Insight into metabolic dysregulation of polycystic ovary syndrome utilizing metabolomic signatures: a narrative review.

Polycystic ovary syndrome (PCOS) is a complex multifactorial endocrinopathy affecting reproductive aged women globally, whose presentation is strongly influenced by genetic makeup, ethnic, and geographic diversity leaving these affected women substantially predisposed to reproductive and metabolic perturbations. Sophisticated techniques spanning genomics, proteomics, epigenomics, and transcriptomics have been harnessed to comprehensively understand the enigmatic pathophysiology of PCOS, however, conclusive markers for PCOS are still lacking today. Metabolomics represents a paradigm shift in biotechnological advances enabling the simultaneous identification and quantification of metabolites and the use of this approach has added yet another dimension to help unravel the strong metabolic component of PCOS.

Molecular Imaging of Ovarian Follicles and Tumors With Near-Infrared II Bioconjugates.

Follicular tracking is typically conducted using ultrasound technology, but its effectiveness is constrained by limited resolution. High-resolution imaging of deep tissues can be accomplished using luminescence imaging in the near-infrared II window (NIR-II, 1000-1700 nm); however, the contrast agents that are used lack specificity. Here, it is reported that the FDA-approved indocyanine green (ICG)-conjugated recombinant human chorionic gonadotropin (hCG) protein can target early follicles with long-term effectiveness.
