The COVID-19 pandemic substantially disrupted healthcare utilization patterns, globally. South Korea had been praised widely in its efforts to contain the spread of pandemic, which may have contributed a significantly smaller reduction compared neighboring countries. However, it remains unknown how impacted patterns across population sub-groups, particularly vulnerable patient groups Korea. This paper quantifies changes attributable and vaccination by sub-groups.
Although conventional topical approaches for treating psoriasis have been offered as an alternative, there are still unmet medical needs such low skin-penetrating efficacy and off-target adverse effects. A hyaluronic acid nanoparticle (HA-NP) formed by self-assembly of HA-hydrophobic moiety conjugates has broadly studied a nanocarrier long-term target-specific delivery drugs, owing to their excellent physicochemical biological characteristics. Here, we identify HA-NPs therapeutics using in...
The link between long-term exposure to tropospheric ozone (O3) and risk of lung cancer mortality remains uncertain. We aimed provide new insights into the association O3 in Korea. A nested case-control study was conducted within a cancer-free cohort 1,731,513 individuals who underwent health screenings provided by National Health Insurance Service 2006-2007. total 7,133 deaths that occurred from January 1, 2012, December 31, 2021, were matched 28,532 controls at 1:4 ratio based on propensity...
Throughout the COVID-19 pandemic, pregnant women have been classified as a vulnerable population. However, evidence on effect of infection during pregnancy maternal and neonatal outcomes is still uncertain, related research comprising large population in Asian countries limited. We constructed national cohort including mothers children (369,887 pairs) registered Prevention Agency-COVID-19-National Health Insurance Service (COV-N), from January 1, 2020 to March 31, 2022. performed propensity...
Exposure to heavy metals such as lead, cadmium, and mercury poses serious health risks pregnant women because of their high toxicity. In this study, we investigated the associations metal exposure with birth outcomes Korean infants. Data 5,215 between 2015 2019 were analyzed. This study was part Children's Environmental Health (Ko-CHENS) study. Linear regression logistic analyses used examine effects concentrations on weight, small for gestational age, large age after adjusting maternal...
Bisphenols are endocrine disruptors that may be associated with altered fetal growth in humans, and they have similar biological functions to mimic hormones. In addition, aggregated chemicals showed an adverse effect although individual concentration was at a low level. However, most studies between bisphenols birth outcomes focused on the of bisphenol. Thus, we explored associations urinary bisphenol mixtures outcomes. We conducted prospective cohort study South Korea. One hundred eighty...
Hypertension is a major cause of end-stage renal disease, and blood pressure (BP) control crucial in patients with chronic kidney disease (CKD). However, it generally inadequately controlled CKD patients. We investigated the prevalence inadequate BP its related factors, based on stage.We analyzed health examination sample cohort database, which consisted randomly selected participants among all citizens who received provided by National Health Insurance Service Korea 2012 2013.There were...
Background: The effects of each blood pressure index [systolic and diastolic (SBP, DBP), pulse (PP), mean arterial (MAP)] on the occurrence mortality cardiovascular (CV) events have not yet been investigated in prehypertensive populations.Methods: A total 30,258 Korean participants underwent periodic health examination between 2003 2004 were enrolled, associations BP components with CV investigated. Moreover, based DBP [80 ≤ <90 mmHg (N = 21,323) <80 8,935)], also evaluated.Results:...
Abstract Background To prevent tobacco use in Korea, the national quitline number was added to packages December 2012, prices were raised by 80% January 2015, and graphic health warning labels placed on 2016. This study evaluated association of these packaging pricing policies with suicide mortality Korea. Methods Monthly from obtained Cause-of-Death Statistics Korea 2007 2019. Interrupted time-series analysis performed using segmented Poisson regression models. Relative risks (RRs) 95%...
Environmental phenols have been suggested as diabetogens but evidence from prospective cohort studies is limited. We examined associations between urinary concentrations of and parabens, assessed at two time-points, incident diabetes in the Study Women's Health Across Nation (SWAN).We 1,299 women, aged 45-56 years, who were diabetes-free baseline SWAN Multi-Pollutant (MPS) (1999-2000) followed through January 2017. Urinary bisphenol-A, bisphenol-F, triclosan, 2,4-dichlorophenol,...
Background: The COVID-19 pandemic substantially disrupted the normal patterns of healthcare utilization globally. South Korea had been praised widely in its efforts to contain spread pandemic, which possibly contributed a significantly smaller reduction compared neighboring countries. However, it remains unknown how impacted on pattern across population sub-groups, particularly vulnerable patient groups Korea. This paper quantifies changes attributable and vaccination by...
Abstract The time at which hypertension treatment should be initiated for different age groups and sexes remains controversial. We aimed to determine whether the association between blood pressure (BP) major adverse cardiovascular events (MACE) varies with sex. This study enrolled 327,328 subjects who had not taken antihypertensive medication in Korean National Health Service-National Screening Cohort 2002 2003. Participants were categorized into four according 2017 American College of...
Abstract There is no known study regarding the usefulness of each blood pressure (BP) component based on stratification by age and sex for predicting cardiovascular (CV) events among hypertensive populations without chronic kidney disease (CKD) or diabetes mellitus (DM). This was performed to investigate association BP components CV in a Korean population according sex. A total 22,853 participants CKD DM were stratified into six groups [40–49, 50–59, 60 years older] In group, multivariate...
대학교의 한 강의동에 있는 16개 강의실에 비치되어 의자 1,000개를 피전사체(potential recipient)로 선정해 미세증거물의 종류인 글리터의 분포를 연구하였다. 비치된 의자의 인체와 접촉하는 표면을 테이프로 전사하고 테이프를 현미경으로 관찰한 결과 조사 대상으로 삼은 강의실의 68.8 %에 해당하는 11개 의자에서 12점의 글리터가 발견되었다. 이는 1,000개 1.1%에 발견되었다고도 해석할 수 결과로서 이런 결과를 볼 때 글리터는 다른 사건현장에서도 나타날 가능성이 높은 미세증거물인 것을 알 있다. 발견된 각각의 육안 및 모양, 크기, 두께, 색상, 홀로그램 존재여부를 검사하였고 검사가 끝난 적외선분광광도계로 옮겨서 양쪽 면의 코팅성분을 화학적으로 분석함으로서 글리터 중 서로 동일한 있는지 확인하였다. 확인 2점은 동일시기에 동일물체에서 탈락된 특성이, 생산라인에서 만들어진 종류의 글리터로 특징이 나타났고, 8점은 밝혀졌다. 두 개의 강의실 해석하기 위해...
For better understanding of carbon cycle dynamics an agro-ecosystem, accurate assessment seasonal and daily <TEX>$CO_2$</TEX> flux is essential to understand the relationship between various environmental factors crop productivity. We developed automatic sliding canopy chamber (ASCC) system that measured continuous net ecosystem productivity (NEP) over whole growing season under natural meteorological rhythm. The ASCC was composed two main parts which were part for measuring NEP, opening...
Fire can affect microbial community structure of soil through altered environmental conditions, nutrient availability, and biotic source for re-colonization. We examined the influence fire on chemical properties enzyme activities 10 months. also characterized ester-linked fatty acid analysis(EL-FAME). For this study, we established five burned plots(1*1 m) 5 unburned plots outside margin fire. Soil was sampled three cores in a each composited analysis at 1, 3, 5, 8, month after The caused an...
