Background: Studies report high levels of inflammatory markers in women with polycystic ovary syndrome (PCOS), reflecting chronic low-grade inflammation. This inflammation is thought to be associated with insulin resistance. We aim to evaluate inflammatory markers [high sensitivity C reactive protein (CRP) and interleukin 6] and insulin resistance in women with PCOS in Yaoundé, Cameroon.
Methods: We conducted a comparative cross-sectional study including 32 women with PCOS aged between 18 and 44 years and 32 controls matched for age and body mass index (BMI). Homeostasis model assessment of insulin resistance (HOMA-IR) index calculated using C peptide levels was used to evaluate insulin resistance. Serum levels of high sensitivity CRP (hsCRP) and interleukin 6 (IL-6) were measured. Comparisons were made using the Student's -test and non-parametric tests (Mann-Whitney -test, Kruskal-Wallis test).
Results: We found that the median [25th-75th percentile] level of hsCRP was significantly higher in women with PCOS compared to the controls (0.63 [0.32-3.81] mg/L 0.47 [0.15-1.04] mg/L; =0.01), while IL-6 levels were not different (8.61 [4.1-33.79] pg/mL for PCOS 8.80 [5.28-38.85] pg/mL for controls; =0.51). We noted that women with PCOS had a higher HOMA-IR index (1.15±0.90 0.77±0.38; =0.03). However, there was no correlation between hsCRP level and the HOMA-IR index (Spearman correlation coefficient=0.10; =0.62).
Conclusion: PCOS is associated with an increased level of hsCRP and insulin resistance in Cameroonian women. This exploratory study provides baseline evidence for larger-scale studies.

Background/objectives: Obesity is associated with numerous metabolic complications including insulin resistance, dyslipidemia, and a reduced capacity for physical activity. Whole-body ablation of liver fatty acid-binding protein (LFABP) in mice was shown to alleviate several of these metabolic complications; high fat (HF) fed LFABP knockout (LFABP ) mice developed higher fat mass than their wild-type (WT) counterparts but displayed a metabolically healthy obese (MHO) phenotype with normoglycemia, normoinsulinemia, and reduced hepatic steatosis compared with WT. LFABP is expressed in both liver and intestine, thus in the present study, LFABP conditional knockout (cKO) mice were generated to determine the contributions of LFABP specifically within the liver or the intestine to the whole body phenotype of the global knockout.

Nevertheless, the causal correlation between SP and serum metabolites, and the biological signaling pathways involved, is still not well understood. We performed a bidirectional two-sample Mendelian randomization (MR) analysis to examine the causal relationships between 1091 levels and 309 ratios of metabolites with SP traits, alongside investigating the relevant biological signaling pathways.

Microgreens of Brassica plants have attracted increasing research interest in the management of the prevailing epidemic of Type 2 diabetes mellitus (T2DM) because of their high nutritional value. This study evaluated the antidiabetic effects of Microgreens Ethanolic Extract (BMEE) in type-2 diabetic rats. For the normoglycemic assay, rats were divided into five groups and received a single oral dose of 100, 250, and 500 mg/kg of BMEE while the control groups received distilled water and Glibenclamide.

The purpose of this study is to examine the pregestational BMI value that results in insulin use in Japanese patients with gestational diabetes mellitus (GDM) and to assess whether the type of GDM treatment affects postpartum glucose tolerance. This retrospective study included 21 GDM patients treated until parturition at our department from 2013 to 2017. We calculated the pregestational BMI related to insulin treatment and the significant elevation in homeostasis model assessment of insulin resistance (HOMA-IR) by receiver operating characteristics curve (ROC) analysis.

Background Polycystic ovary syndrome (PCOS) poses a significant health concern among reproductive-aged women and is characterized by ovarian dysfunction, hyperandrogenism, and insulin resistance. This study aims to assess the efficacy and safety of metformin and myo-inositol combination therapy compared to metformin monotherapy in patients with PCOS. Materials and methods This was a phase III, double-blind, randomized controlled clinical trial.
