Background: Only a limited number of neuroimaging studies have explored the effects ambient air pollution in adults. The prior investigated only cortical volume, and they reported mixed findings, particularly for gray matter. Furthermore, association between nitrogen dioxide (NO2) markers has been little studied Objectives: We long-term exposure to pollutants (NO2, particulate matter (PM) with aerodynamic diameters ≤10μm (PM10) ≤2.5μm (PM2.5), markers. Methods: study included 427 men 530...
The goal of this study was to investigate the short-term effect ambient air pollution on emergency department (ED) visits in Seoul for asthma according patients' prior history allergic diseases.Data ED from 2005 2009 were obtained Health Insurance Review and Assessment Service. To evaluate risk related pollutants (carbon monoxide [CO], nitrogen dioxide [NO2], ozone [O3], sulfur [SO2], particulate matter with an aerodynamic diameter <10 μm [PM10]), a generalized additive model Poisson...
Little is known about the effect of air pollution on Alzheimer's disease (AD)-specific brain structural pathologies. There also a lack evidence whether this leads to poorer cognitive function. We investigated whether, and extent which, AD-like cortical atrophy mediated association between exposures function in dementia-free adults. used cross-sectional data from 640 participants who underwent magnetic resonance imaging Montreal Cognitive Assessment (MoCA). Mean thickness (as measure global...
Objectives Many epidemiological studies have suggested that a variety of medical illnesses are associated with suicide. Investigating the time-varying pattern care utilization prior to death in suicides motivated by physical would be helpful for developing suicide prevention programs patients illnesses. Methods Suicides were identified investigator's note from National Police Agency, which was linked data Health Insurance Review and Assessment. We investigated patterns during 1 year using...
Evidence suggests that long-term air pollution exposures may induce depression; however, the influence of physical activity on this effect is unclear. We investigated modification associations between and depression by intensity activity.
Several cross-sectional studies have shown that long-term exposures to air pollutants are associated with smaller brain cortical volume or thickness. Here, we investigated longitudinal associations of pollution thickness and subcortical volume.
Epidemiological studies have revealed associations between the fine particle (PM2.5; aerodynamic diameter <2.5 μm) exposure and cardiovascular disease. Researchers also recently begun investigating association PM2.5 hemorrhagic stroke (HS) identifying subpopulations vulnerable to exposure. Long-term cumulative average may affect risk of HS, these effects be modified by factors.This retrospective study evaluated on time-to-first-diagnosis HS among 62,676 Seoul metropolitan city residents with...
Evidence suggests that technological innovations and reimbursement schemes of the National Health Insurance Service may have impacted management coronary artery disease. Thus, we investigated changes in practice patterns revascularization. Revascularization in-hospital mortality among Koreans ≥20 years old were identified from medical claims filed between 2006 2010. The age- sex-standardized procedure rate per 100,000 person-years was calculated directly distribution 2008 Korean population....
Geographical variations and influential factors of disease prevalence are crucial information enabling optimal allocation limited medical resources prioritization appropriate treatments for each regional unit. The purpose this study was to explore the geographical cardiometabolic with respect 230 administrative districts in South Korea. Global Moran's I calculated determine whether standardized prevalences diseases (hypertension, stroke, diabetes mellitus) were spatially clustered. CART...
Purpose: Inconsistent findings have been reported regarding the effect of ambient temperature on ischemic stroke.Furthermore, little is known about how underlying disease and low socioeconomic status influence association.We, therefore, investigated relationship between emergency department (ED) visits for stroke, aimed to identify susceptible populations.Materials Methods: Using medical claims data, we identified ED stroke during 2005-2009 in Seoul, Korea.We conducted piecewise linear...
The general population is exposed to numerous environmental pollutants, and it remains unclear which pollutants affect the brain, accelerating brain aging increasing risk of dementia. Environmental-Pollution-Induced Neurological Effects study a multi-city prospective cohort aiming comprehensively investigate effect different on structures, neuropsychological function, development dementia in adults. baseline data 3,775 healthy elderly people were collected from August 2014 March 2018....
A positive association between air pollution and both the incidence prevalence of diabetes mellitus (DM) has been reported in some epidemiologic animal studies, but little research evaluated relationship diabetic coma. Diabetic coma is an acute complication DM caused by ketoacidosis or hyperosmolar hyperglycemic state, which characterized extreme hyperglycemia accompanied We conducted a time-series study with generalized additive model using distributed-lag non-linear to assess ambient...
Purpose:The association between liver enzymes and death from external causes has not been examined.We investigated the serum aminotransferase levels external-cause mortality in a large prospective cohort study.Materials Methods: A total of 142322 subjects 35-59 years age who completed baseline examinations 1990 1992 were enrolled.Mortalities identified using certificates.Serum alanine (ALT) aspartate (AST) categorized into quintiles.Sub-distribution hazards ratios 95% confidence intervals...
Background: Since 2015, the national health insurance supporting policy for smoking cessation treatment is implemented, in Korea.We investigated abstinence rate of and factors associated with inpatient program.Methods: The study subjects were 228 participants who admitted to program a local medical center Daegu, Korea, between October, 2015 September, 2016.Participants completed questionnaire, which composed habits, sociodemographic factors, others.The success evaluated by urine cotinine...
