Purpose: Studies suggest that patients with type two diabetes mellitus (T2D) may be at increased risk of post-colonoscopy colorectal cancer (PCCRC). We investigated clinical and molecular characteristics and survival of T2D patients with PCCRC to elucidate how T2D-related PCCRC may arise.
Methods: We identified T2D patients with colorectal cancer (CRC) from 1995 to 2015 and computed prevalence ratios (PRs) comparing clinical and molecular characteristics of CRC in T2D patients with PCCRC vs. in T2D patients with colonoscopy-detected CRC (dCRC). We also followed T2D patients from the diagnosis of PCCRC/dCRC until death, emigration, or study end and compared mortality using Cox-proportional hazards regression models adjusted for sex, age, year of CRC diagnosis, and CRC stage.
Results: Compared with dCRC, PCCRC was associated with a higher prevalence of proximal CRCs (54% vs. 40%; PR: 1.43, 95% confidence interval [CI] 1.27-1.62) in T2D patients. We found no difference between PCCRC vs. dCRC for CRC stage, histology, and mismatch repair status. The proportion of CRCs that could be categorized as PCCRC decreased over time. Within one year after CRC, 63% of PCCRC vs. 78% of dCRC patients were alive (hazard ratio [HR] 1.85 [95% CI 1.47-2.31]). Within five years after CRC, 44% of PCCRC vs. 54% of dCRC patients were still alive (HR 1.44 [95% CI 1.11-1.87]).
Conclusion: The increased prevalence of proximally located PCCRCs and the poorer survival may suggest overlooked colorectal lesions as a predominant explanation for T2D-related PCCRC, although altered tumor progression cannot be ruled out.

Background: The microvasculature of the central nervous system (CNS), which delivers oxygen and nutrients and forms a critical barrier protecting the CNS, is deleteriously affected by both Alzheimer's Disease (AD) and Type 2 Diabetes (T2D). Previous studies have shown pericyte dropout and vessel constriction in brain capillaries in AD, while other studies have shown pericyte bridging and dropout in retinal capillaries in T2D. T2D patients have increased risk of AD, suggesting potentially related microvascular pathological mechanisms.

Tirzepatide is a first-in-class dual agonist at receptors for glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic polypeptide (GIP) for the treatment of T2D and obesity with unprecedented efficacy for glycaemic control and reductions in body weight as well as improvements in blood pressure and lipid profile compared with placebo and GLP-1 receptor agonists. To date, clinical trials of tirzepatide have fulfilled the requirement by regulatory authorities of demonstrated cardiovascular safety in high-risk patients. Whether cardiovascular benefits will be found with dual GLP-1/GIP receptor agonists remains uncertain, and the contribution of GIP receptor activation to cardiovascular risk has not been established.

Background: Adipose tissue distribution plays a crucial role in the development of cardiovascular complications. In particular, visceral adipose tissue (VAT) has been linked to insulin resistance (IR) and cardiovascular disease (CVD). However, the relationship between VAT, cardiac dysfunction and the meditation capacity of VAT related to IR has not been fully characterized.

Chronic kidney disease (CKD) in type 2 diabetes (T2D) patients is associated with end-stage renal disease and significant economic burden. While sodium glucose cotransporter-2 inhibitors (SGLT2i) show renal benefits in randomized controlled trials (RCTs), their cost-effectiveness in Thailand remains unclear. This study evaluates the cost-utility of adding SGLT2i (dapagliflozin, empagliflozin, and canagliflozin) to standard of care therapy (SoCT) for T2D patients with CKD in Thailand.

Aims: The aim of this study was to systematically review recommendations on physical activity for adults with type 2 diabetes (T2D).
Methods: Online databases were searched for clinical practice guidelines (CPG), statements, and recommendations. Two authors screened the guidelines based on eligibility criteria.
