Aim: Obesity is a well-established risk factor for type 2 diabetes mellitus (T2DM), with specific anthropometric indices offering even greater predictive value. This study aimed to systematically examine the associations between 17 anthropometric indices and T2DM risk, as well as the predictive value of these indices for T2DM.
Methods: Data from the Shanghai Men's and Women's Health Studies were used. Cox regression models estimated hazard ratios (HRs). Receiver operating characteristic (ROC) curves assessed the predictive performance, with subgroup and sensitivity analyses conducted to evaluate robustness.
Results: The study included 71 356 women and 56 288 men, with a mean follow-up of 17.42 and 12.35 years, respectively. Relative fat mass (RFM) had the highest HR in women (HR per SD = 2.42, 95% CI: 2.34-2.49) and men (HR per SD = 2.22, 95% CI: 2.13-2.31). Abdominal adiposity indices (e.g., WC, waist-to-height ratio [WHtR], body roundness index [BRI]) outperformed general adiposity indices (e.g., BMI) in predicting T2DM risk.
Conclusions: Abdominal adiposity indices have significant value in predicting T2DM risk, with notable sex-specific differences. Among these, RFM were better predictors in both women and men. These findings suggest that abdominal obesity indices could be used to inform prevention strategies.
Aims: To compare the risk of infections between GLP-1 receptor agonists (GLP-1 RAs) and SGLT2 inhibitors (SGLT2i) in patients with type 2 diabetes mellitus (T2DM) and advanced chronic kidney disease (CKD).
Methods: Using the TriNetX U.S. Collaborative Network, we conducted a retrospective cohort study of adults with T2DM and eGFR ≤ 45 mL/min/1.73 m2 from 2016 to 2023. After 1:1 propensity score matching, 22,393 new users of GLP-1 RAs and SGLT2i were compared. Infection outcomes were analyzed over a 4-year follow-up using Cox models and Kaplan-Meier analysis.
Results: GLP-1 RA use was associated with a modest increase in overall infection risk compared to SGLT2i (HR 1.04, 95% CI: 1.00-1.07; P = 0.044). Notably, higher risks were observed for biliary tract infections (HR 1.37), catheter-related infections (HR 1.34), and infective endocarditis (HR 1.31). No differences were seen in pneumonia, sepsis, or urinary tract infections. Subgroup analyses showed consistent trends across age, sex, BMI, and cardiovascular status.
Conclusions: In patients with T2DM and advanced CKD, GLP-1 RAs were associated with higher risks of select infections compared to SGLT2i. These findings highlight the need for careful infection monitoring in this vulnerable population.
Aims: Glucagon-like peptide-1 receptor agonists (GLP-1 RA) have demonstrated cardioprotective effects; however, their association with cardiomyopathy remains unclear among patients with cancer and type 2 diabetes mellitus (T2D) treated with chemotherapy, radiation, or immunotherapy. We evaluated whether GLP-1 RA initiation reduces cardiomyopathy risk compared with metformin.
Methods: We conducted a retrospective cohort study using a target trial emulation framework within a large global electronic health record database. Adults aged 18-75 years with cancer and T2D, and prior exposure to chemotherapy, radiation, or immunotherapy were included. Treatment strategies were initiation of GLP-1 RA or metformin between January 2006 and July 2024. The primary outcome was incident cardiomyopathy. A 1:1 propensity score-matched cohort was created, and risk differences (RD) and hazard ratios (HR) were estimated.
Results: Among 10,382 matched patients, cardiomyopathy risk at 18.5 years was lower among GLP-1 RA initiators than metformin initiators (0.31% vs 0.94%; RD - 0.64%, 95% CI - 0.90 to - 0.30; HR 0.43, 95% CI 0.24-0.76). Results were consistent across high-risk subgroups.
Conclusions: GLP-1 RA initiation was associated with a lower risk of cardiomyopathy compared with metformin among patients with cancer and T2D, supporting a potential role for GLP-1 RA in cardio-oncology prevention strategies.
Aims: This study examines the incidence of anxiety, depression, and suicidality after treatment initiation with antihyperglycemic mediations in patients with type 2 diabetes (T2D) which take metformin as first-line treatment.
Methods: A large cohort study was conducted using TriNetX electronic health records andincluded adults (≥18 years) with T2D who used metformin and initiated GLP-1 RAs, SGLT2i, DPP4i, or SU between 1 April 2013 and 31 December 2019.
Results: Among 100,500 patients, 16,424 started using GLP-1 RAs, 13,855 SGLT2i, 27,614 DPP4i, and 42,607 SU. In a median follow-up of 5.5 years, GLP-1 RAs were associated with a higher risk of depression compared to SGLT2i (HR 1.19, 95% CI 1.11-1.28), and DPP4i (HR 1.06, 95% CI 1.00-1.13) but not SU. Anxiety disorder risk was also higher for GLP-1 RAs versus SGLT2i (HR 1.09, 95% CI 1.02- 1.16) and DPP4i (HR 1.07, 95% CI 1.02-1.13) but not SU. On the contrary, GLP-1 RAs were associated with a lower risk for suicidal ideation in comparison with SU (HR 0.62, 95% CI 0.44-0.87).
Conclusions: GLP-1 RAs are associated with higher risk of anxiety and depression but no difference in suicidality and self-harm in comparison to SGLT2i, DPP4i, and lower suicidality risk compared to SU.
