Abstract Fine particulate matters less than 2.5 µm (PM ) in the ambient atmosphere are strongly associated with adverse health effects. However, it is unlikely that all fine particles equally toxic view of their different sizes and chemical components. Toxicity produced from various combustion sources (diesel engine, gasoline biomass burning (rice straw pine stem burning), coal combustion) non-combustion (road dust including sea spray aerosols, ammonium sulfate, nitrate, secondary organic...
In order to control the spread of COVID-19, social distancing measures were implemented in many countries. This study investigated changes air pollution during after COVID-19 outbreak Korea. Ambient PM
Background:The coronavirus disease 2019 (COVID-19) pandemic is an emerging threat worldwide.It remains unclear how comorbidities affect the risk of infection and severity COVID-19.Methods: This a nationwide retrospective case-control study 219,961 individuals, aged 18 years or older, whose medical costs for COVID-19 testing were claimed until May 15, 2020.COVID-19 diagnosis identified from reimbursement data using codes on basis respiratory support use, respectively.Odds ratios (ORs)...
Air pollution is an important public health concern and the ocular surface continuously exposed to pollutants in outdoor air. Ocular abnormalities related air are thought be a subtype of dry eye disease (DED). However, date, there no large-scale study evaluating association between DED that includes multiple pollutants.To investigate associations Korean population.A population-based cross-sectional using data on 16 824 participants fifth Korea National Health Nutrition Examination Survey was...
Purpose To determine the preoperative magnetic resonance (MR) imaging findings potentially most useful for predicting cytokeratin 19 (CK19)-positive hepatocellular carcinoma (HCC) and to evaluate prognosis after curative resection in patients with a single HCC lesion positive CK19 compared who are negative CK19. Materials Methods The institutional review board approved this study waived requirement informed consent. Two hundred four CK19-negative 38 CK19-positive underwent gadoxetic...
Although cadmium and lead are known risk factors for hearing loss in animal models, few epidemiologic studies have been conducted on their associations with ability the general population.We investigated between blood exposure U.S. population while controlling noise other major contributing to loss.We analyzed data from 3,698 adults 20-69 years of age who had randomly assigned National Health Nutrition Examination Survey (NHANES) 1999-2004 Audiometry Component. Pure-tone averages (PTA)...

The prevalence of hearing loss increases rapidly with aging. Hearing is common in all age groups, even young adults and adolescents. A growing body evidence has suggested that heavy metals have ototoxic effects, yet few epidemiological studies investigated the association between a general population includes adolescents.We examined environmental exposures to lead, mercury, cadmium risk adolescents while controlling for potential confounding factors, including noise clinical factors.We...
Despite evidence indicating the presence of per- and poly-fluoroalkyl substances (PFAS) in contact lenses (CL), it remains unclear whether CL use increases PFAS exposure general population. We aimed to determine users have higher serum concentrations than non-users, using data 1660 adults aged 20-39 years participating National Health Nutrition Examination Survey 1999-2000 2003-2008. classified individuals into non-users record vision correction types during a test. Serum six individual were...
Noise exposure is a well-known contributor to work-related hearing loss. Recent biological evidence suggests that ototoxic chemicals such as organic solvents and heavy metals may be additional contributors However, in industrial settings, it difficult determine the risks of loss due these workplaces accompanied by excessive noise exposure. A few studies suggest effect enhanced chemicals. Therefore, this study investigated whether co-exposure and/or workplace modifies risk on background...
Purpose This study aimed to report a case of microplastics (MPs) detection in pterygium patient's tissue. Case A specimen was obtained from the right eye 43-year-old woman by surgical removal recurred pterygium. The number, morphology, and material type MPs were identified using Raman microscopy scanning electron microscopy. Ten detected pterygium, which corresponded polyethylene (PE) (n = 7), polystyrene (PS) 2), polypropylene (PP) 1). size ranged 5–9 µm 5, PE or PS), 10–19 4, PE), 50–99 1,...
Purpose To investigate the association between dry eye disease (DED) and intraocular pressure (IOP) in general adult population of South Korea. Methods We enrolled 13,194 adults (age ≥19 years) who had participated fifth Korea National Health Nutrition Examination Survey conducted from 2010 to 2012. IOP was measured using Goldman applanation tonometry. DED defined as presence self-reported symptoms along with a diagnosis by an ophthalmologist. As correlation left right eyes high ( r =...
Objectives Although occupational noise is a well known risk factor for hearing loss, little epidemiological evidence has been reported on its association with loss in the general population, part, because of difficulty exposure assessment. This study introduced quantitative assessment tool using Occupational Information Network (O*NET) database and evaluated applicability research data from National Health Nutrition Examination Survey (NHANES) 1999–2004. Methods The O*NET were assessed by...
Although biologically plausible, few studies have linked cadmium exposure to depression or muscle strength. Herein, we hypothesized that blood concentrations are associated with and lower handgrip strength in a community-dwelling elderly population.Data from 983 participants who completed up 3 surveys between 2012 2015 were analyzed. At every survey, assessed depressive status using the Korean version of Geriatric Depression Scale-Short Form (SGDS-K) measured levels (mean, 1.24 μg/L). We...
Although previous studies have suggested that meteorological factors and air pollutants can cause dry eye disease (DED), few clinical cohort determined the individual combined effects of these on DED. We investigated (humidity temperature) [particles with a diameter ≤ 2.5 $$\upmu$$ m (PM2.5), ozone (O3), nitrogen dioxide (NO2), carbon monoxide (CO)] A retrospective study was conducted 53 DED patients. evaluated by Symptom Assessment in Dry Eye (SANDE), tear secretion, film break-up time...
