Forkhead box O (FOXO) transcription factors have been implicated in the development and differentiation of the immune cells. FOXO3 plays a crucial role in physiologic and pathologic immune response. FOXO3, cooperatively with FOXO1, control the development and function of Foxp3 regulatory T cells (T). Since the lack of T-mediated control has fundamental impact on type 1 diabetes mellitus (T1DM) development, we investigated expression in patients with T1DM. expression was estimated in peripheral blood mononuclear cells (PBMCs) from newly diagnosed T1DM pediatric patients ( = 28) and age-matched healthy donors ( = 27) by reahavel-time PCR and TaqMan gene expression assays. Expression analysis revealed significant upregulation of in T1DM ( = 0.0005). Stratification of the T1DM group according to the presence of initial diabetic ketoacidosis (DKA) did not indicate differences in expression in patients with DKA compared to a mild T1DM onset ( > 0.05). In conclusion, overexpression of is correlated with the ongoing islet autoimmune destruction and might suggest a potential role for this gene in the pathogenesis of type 1 diabetes mellitus.

Use of SGLT2 Inhibitors in Frail Older Adults is Associated with Increased Survival: A Retrospective Study.

Curr Pharm Des

January 2025

Department of Health Promotion, Mother and Child Care, Internal Medicine and Medical Specialties, University of Palermo, Palermo, Italy.

Background: In recent years, sodium-glucose co-transporter 2 inhibitors (SGLT2i) have emerged as a valuable treatment for type 2 diabetes (T2D) and heart failure. Despite these medications seeming to be safe in older people, the literature about SGLT2i and frailty is still limited. This study aims to evaluate whether SGLT2i use is associated with increased survival in older adults and if frailty can affect the findings.

Current Perspectives of Diabetic Dyslipidemia and Treatment Modalities.

Curr Med Chem

January 2025

Cukurova University, Faculty of Medicine, Division of Endocrinology, Adana, Turkey.

Introduction: Diabetes mellitus is associated with an increased risk of atherosclerosis related to dyslipidemia. Although the terms hyperlipidemia and Diabetes Mellitus [DM] or diabetic dyslipidemia are interrelated to each other, these two conditions have some differences.

Aim: This study aimed to highlight possible mechanisms of hyperlipidemia and/or dyslipidemia in diabetic patients, which can be treated with available and newer hypolipidemic drugs.

Glucagon-like peptide-1 receptor agonists (GLP-1RAs), also known as incretin mimetics, have significantly revolutionized the treatment of type 2 diabetes mellitus (T2DM) and obesity worldwide, far exceeding initial expectations regarding their global prescription. This class of medications has demonstrated weight losses of up to 20 % of baseline body weight. Beyond their proven benefits in T2DM and obesity, GLP-1RAs, as well as dual and triple agonists (GLP-1/GIP/glucagon), are being investigated for their effects on conditions such as metabolic-associated steatotic liver disease, various cardiovascular disorders, neurocognitive impairments, and certain addictions.

Background: Diabetes mellitus and periodontitis are two common chronic diseases with bidirectional relationship. Considering the role of oxidative stress in the pathogenesis of these two diseases, the use of nutritional supplements with antioxidant properties can be useful. The purpose of this study was to determine the effectiveness of daily synbiotic supplement in the management of patients with type 2 diabetes mellitus (T2DM) and periodontal disease (PD) under non-surgical periodontal therapy (NSPT).
