Proteinuria and the risk of Incident atrial fibrillation according to glycemic stages: a nationwide population-based cohort study.

Background: Diabetes mellitus (DM) and proteinuria each independently raise the risk of atrial fibrillation (AF). We aimed to investigate the relationship between proteinuria and the risk of incident AF across glycemic stages.

Methods: A cohort of 4,044,524 individuals without prior AF and type 1 DM was selected from the 2009 Korean National Health Insurance Service health checkup data.

Socioeconomic disparities in influenza vaccination uptake: impact of the COVID-19 pandemic in South Korea.

Background: This study aimed to investigate the sociodemographic and behavioral factors related to increased influenza vaccination uptake during the COVID-19 pandemic in South Korea, particularly among adults not eligible for free vaccination.

Methods: Analyzing data from 78,815 participants in the Korea National Health and Nutrition Examination Survey (2010-2021), we assessed trends in influenza vaccination coverage. Various sociodemographic factors, behavioral aspects, and psychological stress levels were assessed using multivariable logistic regression to evaluate the difference in vaccination response during pre-/post-COVID-19 periods.

Plasma apixaban concentrations and thrombin generation assay parameters in response to dose reduction for atrial fibrillation.

Aims: To investigate plasma apixaban concentrations and thrombin generation assay (TGA) parameters across different apixaban doses in atrial fibrillation patients who had dose-reduction criteria for apixaban.

Methods: This observational study included 374 patients (mean age 75.6 ± 7.

The impact of the COVID-19 pandemic and the expansion of free vaccination policy on influenza vaccination coverage: An analysis of vaccination behavior in South Korea.

Background: Annual vaccination for influenza is globally recommended for some prioritized groups due to its high morbidity and mortality. Until 2019, South Korea has provided free influenza vaccination to children aged ≤12, adults aged ≥65, and pregnant women to enhance vaccination coverage. In 2020, with the COVID-19 pandemic, free flu vaccination was temporarily broadened to adults aged 62-64 and children aged 13-18.
