The global rise of obesity has increased the prevalence of type 2 diabetes mellitus (T2DM) and the risk ofAlzheimer’s disease (AD). The obesity, a key risk factor of T2DM, leads to insulin resistance, which contributesto cognitive decline and potentially AD through shared metabolic pathways. This Commentary highlights theconnection between obesity, T2DM, and AD, suggesting that lifestyle changes like weight loss anddiscontinuation of sugar consumption may help to prevent these conditions. Comprehensive public healthstrategies focusing on diet, exercise, and education are essential to reduce the growing health crisis and improvemetabolic and cognitive health globally.

Assessing the Association between Anti-Diabetic Medication Adherence and Glycemic Control in Type 2 Diabetes

Sun, 01 Jun 2025 08:43:34 +0000

Objective: Adherence to anti-diabetic medications in diabetic patients plays a considerable role in glycemic control, prevention of short-term and long-term morbidities, and diabetes-related mortality. The current study aims to evaluate the factors associated with adherence to medications among patients with type 2 diabetes.

Materials and Methods: The current study was conducted on 366 diabetic patients who were referred to the Institute of Endocrinology and Metabolism. The HbA1C was measured at baseline and then after six months. The validated questionnaire on adherence to refills and medication scale (ARMS) was filled, and factors associated with medication adherence were assessed. The higher ARMS scores represented poorer adherence to the medication.

Results: Diabetic patients with adherence to anti-diabetic agents represented significantly lower levels of HbA1C both at baseline (P< 0.001) and the six-month follow-up (P< 0.001) compared to the non-adherent group. In the correlation analyses, the ARMS score was significantly correlated with the A1C levels measured at the baseline (rs= 0.37, P< 0.001) and after 6 months (rs= 0.40, P< 0.001) as well as the duration of diabetes (rs= 0.16, P= 0.003). The subsequent logistic regression analysis highlighted the use of insulin as the main determinant of adherence to medications (OR: 0.59; 95%CI: 0.35-0.99), after controlling for age, gender, diabetes duration and number of medications.

Conclusion: The current study revealed that adherence to the anti-diabetic medication is associated with remarkably improved glycemic control. Diabetes duration and insulin use were inversely correlated with adherence to medication, while there was no association with age, gender, numbers of drugs.

Tamer A. Addissouky — Sun, 01 Jun 2025 09:10:21 +0000

Metabolic disorders, including obesity and type 2 diabetes, have reached epidemic proportions globally, necessitating novel therapeutic approaches. The gut-brain axis, particularly gut hormones, plays a crucial role in metabolic regulation, offering promising targets for intervention. This review aims to synthesize current knowledge on gut hormone-based therapies for metabolic disorders, focusing on their mechanisms of action and therapeutic potential. Gut hormones, including GLP-1, GIP, PYY, ghrelin, and oxyntomodulin, orchestrate complex physiological responses to nutrient intake, influencing insulin secretion, appetite, and energy expenditure. Recent advancements in incretin-based therapies, particularly GLP-1 receptor agonists and dual GLP-1/GIP agonists, have shown remarkable efficacy in improving glycemic control and promoting weight loss. These therapies exploit the synergistic actions of multiple gut hormones, offering a more comprehensive approach to metabolic regulation. Emerging research on PYY analogs and ghrelin antagonists further expands the therapeutic landscape. However, challenges remain in optimizing delivery methods, ensuring long-term efficacy, and mitigating potential side effects. Gut hormone-based therapies represent a paradigm shift in the management of metabolic disorders. By harnessing the intricate signaling networks of the gut-brain axis, these innovative approaches offer the potential for more effective and targeted interventions in obesity and type 2 diabetes, paving the way for personalized treatment strategies in metabolic medicine.
