Rates of obesity and diabetes have risen significantly in recent years and are projected to increase even further in the coming decades. Obesity and diabetes are associated with increased risk of certain tumours, with the strongest relationships demonstrated for colorectal, post-menopausal breast, and endometrial cancer. Another important risk factor for cancer development is aging. Aging is characterized by chronic inflammation and immunosenescence, and accelerated by obesity, which may further stimulate the development of cancer. In this review, we summarize recent literature on the complex interactions between obesity, diabetes, aging, and cancer risk and mortality. We will also provide an overview of both epidemiological as well as pathophysiologic data and their clinical implications. In the context of an aging population and anticipated rise in rates of obesity and diabetes, a better understanding of how these factors interact and impact on cancer risk and prognosis will be important in helping to guide therapeutic interventions.

Glucagon-like peptide-1 receptor agonists (GLP-1 RAs) are emerging as an important class of drugs in the management of Type 2 Diabetes Mellitus (T2DM) and obesity. There are rising concerns of pulmonary aspiration with these medications due to drug-induced gastroparesis. While definitive association is uncertain, it is essential to be prudent and manage these patients as per the current evidence and recommendations.

Premature Coronary Artery Disease Presenting as STEMI in a Teenager.

J Investig Med High Impact Case Rep

January 2025

LSU Health Shreveport, LA, USA.

An 18-year-old teenager with significant atherosclerotic cardiovascular disease (ASCVD) risk factors developed acute chest pain. His electrocardiogram showed inferior ST-segment elevations. Emergent coronary angiogram revealed complete thrombotic occlusion of the right coronary artery.

This study investigates the potential synergistic effects of extracts from (turmeric), (Arabica coffee beans), and (chili peppers) in reducing oxidative stress and inflammation, which are associated with metabolic disorders such as obesity, diabetes, and cardiovascular diseases. Using a systematic design of experiment (DoE) optimization approach, an optimal extract ratio of 1:3:4 (turmeric: coffee: chili) was identified. The efficacy of the extract combination was assessed through various antioxidant assays, inhibition of inflammation-related gene expression, and safety testing via the 3-(4,5-dimethylthazolk-2-yl)-2,5-diphenyl tetrazolium bromide (MTT) assay.

Effects of the Mediterranean Diet on the Components of Metabolic Syndrome Concerning the Cardiometabolic Risk.

Nutrients

Internal Medicine and Stroke Care Ward, Department of Promoting Health, Maternal-Infant, Excellence and Internal and Specialized Medicine (Promise) G. D'Alessandro, University of Palermo, 90127 Palermo, Italy.

Metabolic syndrome is a cluster of risk factors, including abdominal obesity, insulin resistance, hypertension, dyslipidemia (intended as an increase in triglyceride levels and a reduction in HDL cholesterol levels), and elevated fasting glucose, that increase the risk of cardiovascular disease and type 2 diabetes. With the rising prevalence of metabolic syndrome, effective dietary interventions are essential in reducing these health risks. The Mediterranean diet, rich in fruits, vegetables, whole grains, legumes, nuts, and olive oil and moderate in fish and poultry, has shown promise in addressing metabolic syndrome and its associated components.

Beneficial Effects of a Moderately High-Protein Diet on Telomere Length in Subjects with Overweight or Obesity.

Nutrients

January 2025

Department of Nutrition, Food Sciences and Physiology, Center for Nutrition and Research, University of Navarra, 31008 Pamplona, Spain.

Background And Aim: Telomere length (TL) is a key biomarker of cellular aging, with shorter telomeres associated with age-related diseases. Lifestyle interventions mitigating telomere shortening are essential for preventing such conditions. This study aimed to examine the effects of two weight loss dietary strategies, based on a moderately high-protein (MHP) diet and a low-fat (LF) diet on TL in individuals with overweight or obesity.
