METS-IR combined with four body shape indices and progression to diabetes or reversion to normoglycemia in middle-aged and older adults with prediabetes: a longitudinal analysis of the China Health and Retirement Longitudinal Study

This longitudinal study of Chinese adults with prediabetes demonstrates that combining the metabolic score for insulin resistance (METS-IR) with four body shape indices effectively characterizes the heterogeneous trajectories of glycemic control, where higher baseline products are significantly associated with an increased risk of progressing to diabetes and a decreased likelihood of reverting to normoglycemia.

Lung Cancer Incidence and Mortality in a Nationwide 45-year Prospective Cohort of Persons with Opioid Use Disorder

This nationwide 45-year prospective cohort study reveals that individuals with opioid use disorder face a two-fold increased risk of lung cancer incidence and mortality compared to the general population, with elevated risks observed even among those with low smoking histories, suggesting that current screening criteria may be insufficient for this high-risk group.

Clinical and economic assessments of a personalized support plan to improve adherence to positive airway pressure therapy in patients with obstructive sleep apnea: a randomized controlled trial in Portugal

This randomized controlled trial in Portugal found that while a personalized support plan did not significantly increase mean daily PAP usage over the first three months compared to standard care, it significantly improved long-term adherence rates and symptom control, suggesting potential direct and indirect annual cost savings for the healthcare system.

Metformin use and the risk of gastric cancer: a systematic review and meta-analysis

This systematic review and meta-analysis of nine retrospective cohort studies suggests that metformin use, particularly long-term use of three years or more, is associated with a significantly reduced risk of gastric cancer in patients with type 2 diabetes, although further high-quality prospective studies are needed to confirm these findings due to observed heterogeneity.
