Background Studies have shown that long‐term exposure to air pollution such as fine particulate matter (≤2.5 μm in aerodynamic diameter [ PM 2.5 ]) increases the risk of all‐cause and cardiovascular mortality. To date, however, there are limited data on the impact of air pollution on specific cardiovascular diseases. This study aimed to evaluate cardiovascular effects of long‐term exposure to air pollution among residents of Seoul, Korea. Methods and Results Healthy participants with no previous

This study was performed to evaluate the association of monocyte counts with mortality, the rate of bacteremia, and organ dysfunction and to evaluate whether the change in monocyte counts from the premorbid state to sepsis would differ between survivors and non-survivors in patients with severe sepsis including septic shock. A retrospective analysis of patients with severe sepsis including septic shock was performed. Monocyte counts were categorized into <250, 250-500, 500-750, and ≥750 cells/μL

OBJECTIVE: To investigate the epidemiology of sepsis in Korea and identify risk factors for death in sepsis. METHODS: We conducted a longitudinal, population-based epidemiological study of sepsis in Korea from 2005 to 2012 using the National Health Insurance Service-National Sample Cohort, a population-based cohort representing 2.2% of the Korean population. The primary objective was to assess the incidence, mortality and cost of sepsis. The secondary objective was to identify the risk factors f

It is not easy to ensure optimal prevention of hospital-acquired pressure ulcer (HAPU) in crowded emergency departments (EDs). We hypothesised that a prolonged ED length of stay (LOS) is associated with an increased risk of HAPU. This is a single-centre observational study. Prospectively collected HAPU surveillance data were analysed. Adult (aged ≥20 years) patients admitted through the ED from April 1, 2013 to December 31, 2016 were included. The primary outcome was the development of HAPU with

STUDY DESIGN: Retrospective large population-based study. OBJECTIVE: The aim of this study is to elucidate the association between vertebral compression fractures (VCFs) and pneumonia. SUMMARY OF BACKGROUND DATA: VCF is known to be associated with impaired pulmonary function. However, the risk of developing pneumonia after new-onset VCF has not been evaluated. METHODS: The data source was the National Health Screening Program Cohort, a population-based sample cohort of national health screening
