Abstract
Purpose Type 2 diabetes mellitus (T2DM) is associated with ectopic fat deposition, especially in the liver and pancreas.Therefore, this study aimed to evaluate the relationship between liver fat fraction (LFF), pancreatic fat fraction (PFF), and new-onset T2DM in metabolic dysfunction-associated fatty liver disease (MAFLD) by magnetic resonance imaging (MRI).
Methods This is a retrospective study of patients with MAFLD who underwent abdominal MRI between 2022 and July 2024. LFF and PFF were measured using an axial multi-echo Dixon-based sequence. All participants underwent routine medical history, anthropometric measurements, and laboratory tests. Multivariable stepwise selection models were con-structed to predict PFF and T2DM status based on variables of clinical interest.
Results This study included 80 MAFLD patients with 40 untreated new-onset T2DM and 40 non-T2DM controls. LFF, PFF, and homeostasis model assessment of insulin resistance (HOMA-IR) index were higher in the T2DM group than in the control group. In the new-onset T2DM group, PFF was linearly positively correlated with LFF (rs=0.321, P=0.04) and HOMA-IR (rs=0.350, P=0.03). After adjustment for several metabolic variables, PFF remained an independent risk factor for incident T2DM in MAFLD patients (all P<0.05). The area under the receiver operating characteristic curve for PFF and LFF to predict T2DM was 0.889 and 0.633 (P<0.001 and P=0.03), respectively.
Conclusion In MAFLD patients, PFF, and LFF play a prominent role in new-onset T2DM with high predictive and diag-nostic value.

Aims To characterize switching among GLP-1 receptor agonists (GLP-1 RAs) in a large private-sector cohort in Poland and to quantify therapy- and patient-level associations with switching while accounting for switching opportunity and calendar-time dynamics.
Methods We conducted a retrospective analysis of GLP-1 RA prescription records from the LUX MED network (2018–2025). Switching was defined as any change in agent between consecutive prescriptions. Patients with more than one pre-scription were included (n=42,423). The primary analysis used a transition-level discrete-time hazard model in which each prescription-to-prescription interval contributed one observation, and the outcome was switching at that interval. Current-therapy contrasts were reported relative to subcutaneous semaglutide. Sensitivity analyses examined alternative temporal parameterizations and additional adjustment for elapsed time.
Results Overall, 29.7% of patients switched at least once and 14.3% switched two or more times. In the transition-level analysis, 12,620 patients contributed 27,095 transitions. After adjustment for opportunity and calendar time, liraglutide was associated with substantially lower odds of switching compared with subcutaneous semaglutide (OR, 0.02; 95% CI, 0.01–0.03), whereas oral semaglutide (OR, 1.30; 95% CI, 0.78–2.17) and dulaglutide (OR, 1.70; 95% CI, 0.95–3.04) did not differ significantly. Temporal analyses revealed peaks consistent with episodic substitution and accelerated tirzepatide uptake after market entry. The principal associations remained directionally consistent in sensitivity analyses.
Conclusions Switching among GLP-1 RAs is common and time-dependent. Time-aware modelling identified therapy-spe-cific switching patterns and pronounced temporal variation; reasons for switching remain unmeasured, and the observed associations should be interpreted as hypothesis-generating.
