Additionally, a comparison of FFR-guided percutaneous coronary intervention versus coronary artery bypass grafting in patients with diabetes indicated similar relative benefits, highlighting the need for tailored revascularization strategies (ref: Takahashi doi.org/10.1001/jamacardio.2025.0095/). These findings collectively emphasize the critical need for integrated care approaches that address both diabetes and cardiovascular health.

Research on diabetes and obesity has increasingly focused on the efficacy of anti-obesity medications (AOMs) in patients who do not respond to behavioral treatment. A recent randomized controlled trial demonstrated that AOMs can significantly aid weight loss in early nonresponders, suggesting a need for their inclusion in treatment guidelines (ref: Tronieri doi.org/10.1038/s41591-025-03556-3/). Furthermore, global trends indicate a dramatic rise in adult and childhood obesity rates, with forecasts predicting substantial increases in countries like Nigeria by 2050, which could exacerbate the diabetes epidemic (ref: doi.org/10.1016/S0140-6736(25)00355-1/; doi.org/10.1016/S0140-6736(25)00397-6/). The role of GLP-1 receptor agonists in improving metabolic outcomes for kidney transplant recipients with diabetes has also been highlighted, showing better graft survival rates compared to non-users (ref: Orandi doi.org/10.1016/S2213-8587(24)00371-1/). These findings underscore the multifaceted relationship between obesity and diabetes, necessitating comprehensive strategies for management.

Recent advancements in understanding the genetic underpinnings of metabolic disorders related to diabetes have revealed significant insights.
