A three-year retrospective cohort study of 3,819 participants found that prediabetes subtypes follow distinct trajectories and carry differing risks for early kidney filtration impairment. The work emphasizes heterogeneity within prediabetes rather than treating it as a single uniform risk state. In a separate context, a modeling and clinical biomarker item tied aqueous cytokines in diabetic macular edema to predicting anti-VEGF response, reinforcing the broader theme of stratification by biological signals. Collectively, the research supports a move toward subtype- and biomarker-informed risk prediction across metabolic and organ-specific complications.
