Background: Under-carboxylated osteocalcin (ucOC), the precursor substrate of bone biomarker OC is a potent regulator of energy metabolism by promoting insulin production and adiponectin synthesis and decreasing fat stores. The aim of the present study was to point out the potential role of ucOC in the physiopathology of polycystic ovary syndrome (PCOS), a common disorder defined by the constellation of anovulation, insulinresistance, hyperinsulinemia, obesity and androgen excess.
Methods: In this prospective case-control investigation, 78 young premenopausal women, i.e. 52 PCOS patients and 26 age- and body mass index (BMI)-matched healthy controls, were successively enrolled. Recruitment of PCOS patients was performed according to Androgen Excess-Polycystic Ovary Syndrome (AE-PCOS) Society 2006 criteria. All study participants were subjected to clinical examination, whole-body composition assessment and measurements of serum ucOC, OC (1-49), glucose and lipids, insulin, total testosterone (TT), estradiol, sex-hormone binding globulin (SHBG), high-sensitivity C-reactive protein (Hs-CRP) and β-CrossLaps.
Results: BMI-stratified multivariate analysis revealed significantly higher ucOC levels in PCOS vs. controls in lean (p = 0.001) but not overweight and obese study participants (p = 0.456). Notably, a positive correlation between ucOC and TT (p = 0.018), calculated free testosterone (cFT, p = 0.028) and serum insulin (p = 0.036), respectively, was found to be confined to the lean analysis subgroup. Furthermore, in stepwise multiple regression models, β-CrossLaps and cFT were able to predict 46.71% of serum ucOC variability. (1-43/49)OC failed to be significantly associated to any PCOS trait.
Conclusions: Circulating ucOC concentration is related to key endocrine PCOS characteristics in a weight-dependent manner. Within the bone-pancreas loop, high ucOC may favor insulin release in lean hyperandrogenic women to compensate for impaired insulin sensitivity.

This study aimed to identify shared gene expression related to circadian rhythm disruption in polycystic ovary syndrome (PCOS) and non-alcoholic fatty liver disease (NAFLD) to discover common diagnostic biomarkers. Visceral fat RNA samples were collected from 12 PCOS and 14 non-PCOS patients, a sample size representing the clinical situation and sufficient to capture PCOS gene expression profiles. Along with liver transcriptome profiles from NAFLD patients, these data were analyzed to identify crosstalk circadian rhythm-related genes (CRRGs) between the diseases.

Objectives: To evaluate the association between polycystic ovary syndrome (PCOS) and the risk of differentiated and papillary thyroid cancer.
Methods: We included all individuals assigned female at birth and born during 1962-1996 in Denmark. Information on vital status, PCOS- and cancer diagnoses, and covariates were attained from various Danish nationwide registers.

Background: Polycystic ovary syndrome (PCOS) commonly co-occurs with obesity, medical comorbidities, and psychiatric symptoms. Bariatric surgery is an effective treatment for co-occurring obesity and PCOS. While the incidence of PCOS declines substantially after bariatric surgery, the condition is still present for a subset of women.

Women's health is related to several factors that include physical, mental, and reproductive health. Additionally, the vaginal microbiota modulation performs a fundamental role in the regulation of physiological homeostasis and dysbiosis, which provides us a potential overview of the use of different biotic agents and their implications for female health. The objective of this work was propitiated insights and conception about the influence of probiotics, prebiotics, synbiotics, and postbiotics as adjuvants for prevention/treatment on the main infections that can affect women's health.

Purpose: To explore the impact of high body mass index (BMI) on the embryo quality and clinical outcomes of polycystic ovary syndrome (PCOS) patients, and the possible genes involved.
Methods: Patients who underwent in-vitro fertilization (IVF) treatment and embryo transfer in our center from November 2014 to September 2023, were divided into low BMI PCOS (LBP) group, high BMI PCOS (HBP) group, and high BMI control (HBC) group. Transcriptome sequencing was performed in eight PCOS patients' granulosa cells (GCs).
