Article Synopsis
  • The study looked at how different types of fatty liver disease affect the risk of getting diabetes in adults over about 5 years.
  • It involved 21,178 adults and found that people with certain types of fatty liver were more likely to develop diabetes than those without liver issues.
  • Specifically, those with metabolic dysfunction-associated fatty liver disease (MAFLD) had the highest risk, especially when combined with factors like heavy drinking or certain viral infections.

Article Synopsis
  • - The study investigates whether metabolic dysfunction-associated fatty liver disease (MAFLD) is a better predictor of chronic kidney disease (CKD) risk than nonalcoholic fatty liver disease (NAFLD) based on data from 21,713 adults over 5.3 years.
  • - Results show that MAFLD, along with other groups with metabolic dysregulation, significantly increases the risk of developing CKD, unlike the NAFLD-only group, which showed no increased risk.
  • - The findings suggest that adopting MAFLD criteria could help identify more individuals at risk for CKD, especially those with overweight/obesity, diabetes, excessive alcohol intake, or viral hepatitis.

Background: Pulse transit time and pulse wave velocity (PWV) are related to blood pressure (BP), and there were continuous attempts to use these to predict BP through wearable devices. However, previous studies were conducted on a small scale and could not confirm the relative importance of each variable in predicting BP.

Objective: This study aims to predict systolic blood pressure and diastolic blood pressure based on PWV and to evaluate the relative importance of each clinical variable used in BP prediction models.

Objective: We aimed to determine the mean glucose thresholds to increase the risk of left ventricular diastolic dysfunction (LVDD) and whether visit-to-visit variability of fasting plasma glucose (FPG) and glycated hemoglobin (A1C) could independently increase the risk in a cohort with serial echocardiography.

Methods: This was a 3.5-year (range, 0.
