Article Abstract
Previous studies implicate immune dysregulation in the metabolic changes accompanying obesity and type 2 diabetes. This study investigated the interplay between metabolic and immunological parameters during the progression of type 2 diabetes in an obese Mexican American cohort from Starr County, Texas. Individuals matched for age, gender, and BMI were stratified into five categories: diabetes-free, isolated impaired glucose tolerance, combined glucose impairment (fasting or post-load), type 2 diabetes without complications, and type 2 diabetes with lower extremity complications. Buffy samples were analyzed via Luminex Multiplex Assay for IL-4, IL-17A, MCP-1, and HMGB1. HMGB1 levels were significantly elevated in individuals with prediabetes and the combined glucose intolerance group compared to the diabetes-free group and those with diabetes. Elevated HMGB1 levels positively correlated with Homeostatic Model Assessment (HOMA) for insulin resistance (p = 0.03) and showed a moderate negative correlation with insulin sensitivity (p = 0.060). IL-17A levels were elevated in the diabetes group without complications compared to those with combined glucose impairment. The combined diabetes group exhibited the poorest glycemic control. In summary, HMGB1 is a potential early marker of insulin resistance and diabetes progression in Mexican Americans from an underserved community.

Objective: This study aimed to evaluate the diabetic eye disease screening continuum at two academic centers and identify its barriers.
Research Design And Methods: We analyzed health records from the University of California, San Francisco and University of California, Irvine to identify primary care patients needing diabetic eye screening. We tracked referrals, screenings, diagnoses, and treatments to evaluate predictors and the impact of an automated referral system.

Background: Visceral adipose tissue (VAT) is associated with several cardiometabolic risk factors, particularly metabolic syndrome and insulin resistance. Reference values for VAT vary across populations, genders, and ages. Data on visceral fat in the Algerian population are lacking.

Objective: This study investigates the mechanisms behind exercise capacity in adults with type 2 diabetes mellitus (T2DM), focusing on central and peripheral components, as described by the Fick equation.
Methods: A cross-sectional study of 141 adults with T2DM was conducted, using cardiopulmonary exercise testing, near-infrared spectroscopy (NIRS) and exercise echocardiography. Participants with sufficient-quality NIRS data were stratified into tertiles based on percentage predicted VO₂peak.

There is a lack of longitudinal data on type 2 diabetes (T2D) in low- and middle-income countries. We leveraged the electronic health records (EHR) system of a publicly funded academic institution to establish a retrospective cohort with longitudinal data to facilitate benchmarking, surveillance, and resource planning of a multi-ethnic T2D population in Malaysia. This cohort included 15,702 adults aged ≥ 18 years with T2D who received outpatient care (January 2002-December 2020) from Universiti Malaya Medical Centre (UMMC), Kuala Lumpur, Malaysia.

Importance: As obesity rates rise in the US, managing associated metabolic comorbidities presents a growing burden to the health care system. While bariatric surgery has shown promise in mitigating established metabolic conditions, no large studies have quantified the risk of developing major obesity-related comorbidities after bariatric surgery.
Objective: To identify common metabolic phenotypes for patients eligible for bariatric surgery and to estimate crude and adjusted incidence rates of additional metabolic comorbidities associated with bariatric surgery compared with weight management program (WMP) alone.
