Introduction: Patients with systemic lupus erythematosus (SLE) have a higher prevalence of insulin resistance (IR) and metabolic syndrome (MetS) than controls.
Objective: To evaluate IR in non-diabetic women with SLE by means of biomarkers using high-throughput metabolomic techniques.
Method: Cross-sectional study in patients with SLE. A metabolomic approach was employed using ultra-high performance liquid chromatography coupled with high-resolution mass spectrometry. MetS was evaluated according to NCEP-ATP III criteria.
Results: Seventy patients with SLE were included, out of whom 45 (64.2%) and 27 (38.5%) had IR and MetS, respectively. Patients with IR had a higher body mass index and hypertension more often than those without IR. Chronic damage and disease activity were not related to IR. A Quantose-IR score ≥ 63 was more common in patients with MetS (81.5 vs. 53.5%; p = 0.02). Quantose-IR score was also correlated with the number of criteria for MetS (r: 0.35; p = 0.003).
Conclusions: In non-diabetic women with SLE, the prevalence of IR based on Quantose-IR score was 64.2%.

Introduction: Gut microbiota (GM) has been implicated in gestational diabetes mellitus (GDM), yet longitudinal changes across trimesters remain insufficiently explored.
Methods: This nested cohort study aimed to investigate GM alterations before 24 weeks of gestation and their association with GDM. Ninety-three Chinese participants provided fecal samples during the first and second trimesters.
Association between endogenous estradiol, testosterone, and long-term mortality in adults with prediabetes and diabetes: Evidence from NHANES database.

Aim And Introduction: Diabetes and prediabetes pose significant global public health challenges. Sex steroids, particularly testosterone and estradiol, play crucial roles in various metabolic processes. This study investigates the relationship between sex hormone levels and long-term mortality in adults with prediabetes and diabetes, as well as those without glucose intolerance.

Background And Aim: Cardiovascular disease progresses after menopause. Conventional risk factors, particularly diabetes, for atherosclerosis are well-established predictors of phenotypic arterial disease. The aim of this study is to assess the predictors of subclinical atherosclerosis in asymptomatic non-diabetic postmenopausal women.

Background: A comprehensive evaluation of potential living kidney donors is crucial to ensure their short and long-term safety. We explored differences in kidney biochemical indicators, blood pressure measurements, and glucose control pre- and post-kidney donation between women with pre-diabetes and those with normal glucose levels.
Methods: We performed a prospective cohort study at West Bank and Gaza University hospitals between 2016 and 2022.

Prediabetes is a serious metabolic disorder that is often overlooked and 70% of individuals with prediabetes would eventually develop type 2 diabetes. The diabetogenic effects of pesticides have been reported in toxicological studies but their association with prediabetes is rarely investigated. We aimed to evaluate the association between pesticide exposure and impaired glucose regulation (IGR), including prediabetes (defined as impaired fasting glucose [IFG] and/or impaired glucose tolerance [IGT]) and insulin resistance, in a general U.
