The aims of this study were to assess the biodiversity of periphytic diatom assemblages in fresh, brackish and marine waterbodies of Korea, and to assess the effect of environmental and anthropogenic factors on parameters such as the quantity and biovolume of lipid bodies and deformations of diatoms as early warning measures of anthropogenic impact. Diatom samples were collected from 31 sites (14 freshwater, 10 brackish and 7 marine), which included less impacted (upstream) and impacted (downstream) sites in each water type...

The most recent version of the European Society for Medical Oncology (ESMO) consensus guidelines for the treatment of patients with metastatic colorectal cancer (mCRC) was published in 2016, identifying both a more strategic approach to the administration of the available systemic therapy choices, and a greater emphasis on the use of ablative techniques, including surgery. At the 2016 ESMO Asia Meeting, in December 2016, it was decided by both ESMO and the Japanese Society of Medical Oncology (JSMO) to convene a special guidelines meeting, endorsed by both ESMO and JSMO, immediately after the JSMO 2017 Annual Meeting...

Rickettsiae are associated with a diverse range of invertebrate hosts. Of these, mosquitoes could emerge as one of the most important vectors because of their ability to transmit significant numbers of pathogens and parasites throughout the world. Recent studies have implicated Anopheles gambiae as a potential vector of Rickettsia felis. Herein we report that a metagenome sequencing study identified rickettsial sequence reads in culicine mosquitoes from the Republic of Korea. The detected rickettsiae were characterized by a genus-specific quantitative real-time PCR assay and sequencing of rrs, gltA, 17kDa, ompB, and sca4 genes...

Laboratory Response Network (LRN) laboratories help protect populations from biological and chemical public health threats. We examined the role of LRN biological laboratories in enhancing capacity to detect and respond to public health infectious disease emergencies in South Korea. The model for responding to infectious disease emergencies leverages standardized laboratory testing procedures, a repository of standardized testing reagents, laboratory testing cooperation among hospital sentinel laboratories and reference laboratories, and maintenance of a trained workforce through traditional and on-demand training...

CONTEXT: Attrition is common in longitudinal observational studies in palliative care. Few studies have examined predictors of attrition. OBJECTIVES: To identify patient characteristics at enrollment associated with attrition in palliative oncology outpatient setting. METHODS: In this longitudinal observational study, advanced cancer patients [ACP] enrolled in an outpatient multicenter study were assessed at baseline and 2-5 weeks later. We compared baseline characteristics between patients who returned for follow-up and those who dropped out...

BACKGROUND: Sickness absence has been regarded as an important indicator of workers' health and work productivity. This study is aimed to evaluate the association between depressive symptoms and sickness absence in workers of South Korea. METHODS: We used nationwide cross-sectional survey data from 2889 individuals in the working population aged over 19 years in South Korea. Depressive symptoms were measured using Patient Health Questionnaire-9 (PHQ-9). Those respondents who scored above 10 on PHQ-9 were regarded as having depressive symptoms...

The objective of this study was to determine whether the water effect ratio (WER) or biotic ligand model (BLM) could be applied to efficiently develop water quality criteria (WQC) in Korea. Samples were collected from 12 specific sites along the Yeongsan River (YSR), Korea, including two sewage treatment plants and one estuary lake. A copper toxicity test using Daphnia magna was performed to determine the WER and to compare to the BLM prediction. The results of the WER from YSR samples also indicated significantly different copper toxicities in all sites...

BACKGROUND: Alirocumab, a fully human monoclonal antibody to proprotein convertase subtilisin/kexin type 9, has been shown to provide significant reductions in low-density lipoprotein cholesterol (LDL-C). Data about its efficacy and safety in patients from South Korea and Taiwan are limited. OBJECTIVE: ODYSSEY KT assessed the efficacy and safety of alirocumab in patients from South Korea and Taiwan. METHODS: Patients with hypercholesterolemia at high cardiovascular risk who were on maximally tolerated statin were randomized (1:1) to alirocumab (75 mg every 2 weeks, with dose increase to 150 mg every 2 weeks at week 12 if LDL-C ≥70 mg/dL at week 8) or placebo for 24 weeks...

BACKGROUND: Transmission of Middle East respiratory syndrome (MERS) to health care personnel (HCP) is a major concern. This study aimed to review cases of MERS-related events, such as development of MERS-like symptoms or exposure to patients. METHODS: A MERS screening clinic (MSC) for HCP was setup in the National Medical Center during the MERS outbreak in 2015. Clinical and laboratory data from HCP who visited the MSC were retrospectively reviewed. Additionally, these data were compared with the results of postoutbreak questionnaire surveys and interviews about MERS-related symptoms and risk-related events...

Prenatal exposure to volatile organic compounds may restrict fetal development and adversely influence infants' life. Therefore, we investigated the relationship between prenatal exposure to total volatile organic compounds (TVOC) and postnatal neurobehavioral development. A subsample of 383 pregnant participants was chosen from the prospective birth cohort study of Mother and Children's Environmental Health Study; MOCEH (N=1,751) from three regions of the Republic of Korea (Seoul, Cheon-an, and Ulsan). Participants were enrolled during their first trimester with informed consent...

We analyzed the population genetic structure and demographic history of 20 Lymantria dispar populations from Far East Asia using microsatellite loci and mitochondrial genes. In the microsatellite analysis, the genetic distances based on pairwise FST values ranged from 0.0087 to 0.1171. A NeighborNet network based on pairwise FST genetic distances showed that the 20 regional populations were divided into five groups. Bayesian clustering analysis (K = 3) demonstrated the same groupings. The populations in the Korean Peninsula and adjacent regions, in particular, showed a mixed genetic pattern...

BACKGROUND: Implantable cardioverter defibrillators (ICDs) are lifesaving devices for patients with heart failure (HF) and reduced ejection fraction. However, utilization and determinants of ICD insertion in Asia are poorly defined. We determined the utilization, associations of ICD uptake, patient-perceived barriers to device therapy and, impact of ICDs on mortality in Asian patients with HF. METHODS AND RESULTS: Using the prospective ASIAN-HF (Asian Sudden Cardiac Death in Heart Failure) registry, 5276 patients with symptomatic HF and reduced ejection fraction (HFrEF) from 11 Asian regions and across 3 income regions (high: Hong Kong, Japan, Korea, Singapore, and Taiwan; middle: China, Malaysia, and Thailand; and low: India, Indonesia, and Philippines) were studied...

OBJECTIVE: De novo cancers of head and neck area in solid organ transplantation recipients show standardized incidence ratio (SIR) of 3.8. Immunosuppression following transplantation is suggested to play as a crucial factor in pathogenesis of secondary malignancy. Prognosis of head and neck cancer arising in solid organ transplantation recipients is proven to have poor prognosis. The incidence, risk, prognosis, and survival of de novo malignancy of head and neck area in solid organ transplantation recipients in single-tertiary medical center followed up for 20 years...

BACKGROUND & AIMS: Little is known about the association between non-alcoholic fatty liver disease (NAFLD) and cancer development. This study investigated the cancer incidence rates in NAFLD and analysed the association between NAFLD and cancer development. METHODS: This historical cohort study included subjects who were followed up for >1 year after having a heath checkup at a tertiary hospital in Korea from September 1, 2004 to December 31, 2005. NAFLD was diagnosed by ultrasonographic detection of hepatic steatosis in the absence of other known liver disease, including alcoholic or viral hepatitis...
