AI Article Synopsis
- The study examines the effects of different treatments on metabolic parameters and body composition in obese women with PCOS.
- Treatments included exenatide, dapagliflozin, their combination, extended-release metformin, and phentermine-topiramate, with significant evaluations at the start and after 24 weeks.
- Results showed that the combo therapy (exenatide and dapagliflozin) and phentermine-topiramate led to the greatest weight loss and fat reduction, with combo therapy providing the most substantial improvements in glucose control and insulin sensitivity.
Article Abstract
Context: Glucagon-like peptide-1 receptor agonists and sodium-glucose cotransporter-2 inhibitors reduce weight and improve insulin sensitivity via different mechanisms.
Objective: The efficacy of once-weekly exenatide (EQW) and dapagliflozin (DAPA) alone and coadministered (EQW/DAPA), DAPA/extended-release (ER) metformin (DAPA/MET), and phentermine topiramate extended release (PHEN/TPM) on metabolic parameters, body composition, and sex hormones were examined in obese women with PCOS.
Methods: Nondiabetic women (n = 119; aged 18-45 years) with a body mass index (BMI) greater than 30 and less than 45 and polycystic ovary syndrome (National Institutes of Health criteria) were randomly assigned in a single-blinded fashion to EQW (2 mg weekly); DAPA (10 mg daily), EQW/DAPA (2 mg weekly/10 mg daily), DAPA (10 mg)/MET (2000 mg XR daily), or PHEN (7.5 mg)/TPM (46 mg ER daily) treatment for 24 weeks. Study visits at baseline and 24 weeks included weight, blood pressure (BP), waist (WC) measures, and body composition evaluated by dual-energy x-ray absorptiometry (DXA). Oral glucose tolerance tests were conducted to assess glycemia and mean blood glucose (MBG), and compute insulin sensitivity (SI) and secretion (IS) measures. Sex steroids, free androgen index (FAI), and lipid profiles were measured in the fasting sample.
Results: EQW/DAPA and PHEN/TPM resulted in the most loss of weight and total body fat by DXA, and WC. Despite equivalent reductions in BMI and WC with PHEN/TPM, only EQW/DAPA and EQW resulted in significant improvements in MBG, SI, and IS. Reductions in fasting glucose, testosterone, FAI, and BP were seen with all drugs.
Conclusion: Dual therapy with EQW/DAPA was superior to either alone, DAPA/MET and PHEN/TPM in terms of clinical and metabolic benefits in this patient population.

Polycystic ovary syndrome (PCOS) is a primary endocrine disorder affecting premenopausal women involving metabolic dysregulation. We aimed to screen serum biomarkers in PCOS patients using untargeted lipidomics and ensemble machine learning. Serum from PCOS patients and non-PCOS subjects were collected for untargeted lipidomics analysis.

Purpose Of Review: To evaluate the role of hypothalamic inflammation and gliosis in human obesity pathogenesis and other disease processes influenced by obesity.
Recent Findings: Recent studies using established and novel magnetic resonance imaging (MRI) techniques to assess alterations in hypothalamic microarchitecture in humans support the presence of hypothalamic inflammation and gliosis in adults and children with obesity. Studies also identify prenatal exposure to maternal obesity or diabetes as a risk factor for hypothalamic inflammation and gliosis and increased obesity risk in offspring.
Enhancing repeatability of follicle counting with deep learning reconstruction high-resolution MRI in PCOS patients.

Follicle count, a pivotal metric in the adjunct diagnosis of polycystic ovary syndrome (PCOS), is often underestimated when assessed via transvaginal ultrasonography compared to MRI. Nevertheless, the repeatability of follicle counting using traditional MR images is still compromised by motion artifacts or inadequate spatial resolution. In this prospective study involving 22 PCOS patients, we employed periodically rotated overlapping parallel lines with enhanced reconstruction (PROPELLER) and single-shot fast spin-echo (SSFSE) T2-weighted sequences to suppress motion artifacts in high-resolution ovarian MRI.
View Article and Find Full Text PDFPurpose: Polycystic Ovary Syndrome (PCOS) and Adrenal hyperplasia (CAH) are two pathologic conditions sharing several clinical features (hirsutism, acne, polycystic ovary morphology, metabolic alterations, ovulatory dysfunctions) and especially hyperandrogenism as a common clinical hallmark. Therefore, making a differential diagnosis of the two conditions still remains a great medical challenge.
Methods: In particular, the comparison discussed in this review referred to non-classical form of adrenal hyperplasia (NCAH), which regards the adult population, and the Endocrine Metabolic Syndrome (EMS), following the new set of PCOS diagnostic criteria proposed by the Experts Group on Inositol and Clinical Research, and on PCOS (EGOI-PCOS).

Objective: Polycystic ovary syndrome (PCOS) is a reproductive endocrine disease characterized by reproductive dysfunction and metabolic abnormalities. The purpose of this study was to explore the expression characteristics of coding and non-coding RNAs in granulosa cells of PCOS, and to provide data support for understanding the pathogenesis of PCOS.
Methods: Three patients with PCOS (according to the 2003 Rotterdam diagnostic criteria) and three normal controls were selected.
