This prospective ex vivo and in vitro pharmacodynamic (PD)/pharmacokinetic investigation was conducted in patients with diabetes mellitus with (n = 31) and without chronic kidney disease (n = 30). PD assessments included platelet reactivity index, maximum platelet aggregation, and P2Y reaction units. Ex vivo pharmacokinetic assessments included plasma levels of clopidogrel and its active metabolite. In vitro PD assessments were conducted on baseline samples incubated with escalating concentrations of clopidogrel and its active metabolite. Among patients with diabetes mellitus treated with clopidogrel, impaired renal function was associated with increased maximum platelet aggregation. This finding could be attributed partially to upregulation of the P2Y activity without differences in drug absorption or metabolism.

Characterization of glucagon-like peptide-1 (GLP-1) agonist exposures reported to a single United States poison center.

Rocky Mountain Poison and Drug Safety Center, Denver, CO, USA.
Introduction: Glucagon-like peptide-1 agonists have gained attention in recent years due to their efficacy in managing type II diabetes mellitus and their emerging role in weight management. The purpose of this study was to characterize glucagon-like peptide-1 agonist exposures reported to a single United States regional poison center over nine years, including causes of exposure, associated clinical effects, and potential areas for improving patient education and safety.
Methods: This retrospective cohort study analyzed all poison center calls involving glucagon-like peptide-1 agonists submitted to a single United States regional poison center from 14 January 2014 to 1 May 2023.
Thirty-day unplanned readmissions following hospitalization for atrial fibrillation in a tertiary Syrian center: A real-world observational cohort study.

Department of Cardiovascular Sciences, University of Leicester, Leicester, United Kingdom.
Background: Atrial fibrillation (AF) is the most common arrhythmia worldwide. Data regarding 30-day readmission following index admission for AF in the developing world are poorly described.
Objectives: The study aimed to assess the rate, predictors, and trends of 30-day readmission after index admission for AF in Syria.
Application of adipose tissue-derived stem cell therapy with a clinically relevant dose does not significantly affect atherosclerotic plaque characteristics in a streptozotocin-induced hyperglycaemia mouse model.

Department of Pathology, Amsterdam University Medical Centres (AUMC), Location VUmc, Amsterdam, the Netherlands.
Aims: Diabetes mellitus (DM) induces increased inflammation of atherosclerotic plaques, resulting in elevated plaque instability. Mesenchymal stem cell (MSC) therapy was shown to decrease plaque size and increase stability in non-DM animal models. We now studied the effect of MSC therapy in a streptozotocin-induced hyperglycaemia mouse model using a clinically relevant dose of adipose tissue-derived MSCs (ASCs).

Purpose: This study aimed to evaluate serum cystatin C as a potential biomarker for diabetic retinopathy (DR) in a rural Indian population, addressing the urgent need for effective screening tools amidst rising diabetes prevalence.
Materials And Methods: A cross-sectional study recruited 112 patients with diabetes mellitus from Sambalpur, Odisha, India, categorized into groups with and without DR. Serum cystatin C levels were measured alongside clinical and demographic parameters, using established diagnostic methods.
