Central venous catheters (CVCs) are regularly used in intensive care units, and catheter-related bloodstream infection (CRBSI) remains a leading cause of healthcare-associated infections, particularly in preterm infants. Increased survival rate of extremely-low-birth-weight infants can be partly attributed to routine practice of CVC placement. The most common types of CVCs used in neonatal intensive care units (NICUs) include umbilical venous catheters, peripherally inserted central catheters, a

BACKGROUND: Several studies have examined tracking pattern of blood lipids level during long follow-up periods in Western countries. However, there have been few such studies in Asian populations. METHODS: The Kangwha Study is a community-based prospective cohort study that started in 1986 on Kangwha Island, South Korea. A total of 432 participants (47% men) were enrolled in the study, during which serum total cholesterol, triglycerides, and high-density lipoprotein (HDL) cholesterol levels were

Kimura disease has been known as a chronic inflammatory disease of unknown etiology, since the first report in 1937 and characterized by an increased eosinophil fraction in peripheral blood, increased serum immunoglobulin E (IgE) levels, and lymphoid granuloma with eosinophilic infiltration on histopathological examination. The authors present a 30-year-old man who visited their clinic with a 3-month history of protrusion and conjunctival injection of the right eye. Surgical mass resection was p

Purpose: The purpose of the present study was to examine the validity and reliability of the Korean version of the Eating Disorder Inventory-2 (EDI-2) in Korean patients with eating disorders and healthy controls, and to investigate cultural differences of EDI-2 between a Korean group and a North American standardization sample. Materials and Methods: The Korean version of the EDI-2 was prepared after comprehensive clinical assessment of Korean patients with eating disorders (n=327) as well as f

Higher CRP concentrations were associated with higher mortality in a rural Korean population, and this association was more prominent in men than in women.

Posttraumatic stress disorder (PTSD) is an anxiety-related disorder that occurs after an exposure to an emotionally traumatic event, such as a lifethreatening experience, and that persists with intrusive and distressing emotion-laden memories. It can trigger further mental health problems, such as depression, bipolar disorder, mania and so on. As a large population suffers from these complex diseases, its treatment results in massive secondary costs to society. Recent diagnosis and treatment of

Objectives: Carotid intima-media thickness (CIMT) and the presence of carotid artery plaque are widely used as preclinical markers of atherosclerosis. Due to operator dependency in measuring CIMT, it is important to evaluate the reliability of measuring CIMT and plaque between centers in a multicenter study. The purpose of this study is to evaluate the inter-rater reliability of CIMT and plaque presence among three clinical centers of the Cardiovascular and Metabolic Disease Etiology Research Ce

ABSTRACT This study investigated the effects of N ‐vinyl‐2‐pyrrolidone (NVP) and methacrylic acid (MA) comonomers on the curing characteristics and properties of poly(2‐hydroxyethyl methacrylate) (PHEMA) hydrogel for soft contact lenses. A real‐time temperature measurement system was devised and the exothermic behaviors of hydrogel contact lenses comprising PHEMA, P(HEMA/NVP), and P(HEMA/MA) during oven‐curing condition were analyzed. The results of the real‐time temperature measurement were com

PURPOSE: This study aimed to identify the association between physical activity and health-related quality of life (HRQoL) in middle-aged and elderly individuals with musculoskeletal disorders. METHODS: This study used data from the 2016-2020 Korea National Health and Nutrition Examination Survey (KNHANES). We included only those over 40 years of age diagnosed with one or more of the following: osteoarthritis, rheumatism, and osteoporosis. In total, 4,731 participants (783 men and 3,948 women) w

Introduction: Obesity has been an important issue for global health. The use of the smartphone application might contribute to weight loss. However, there is still little evidence for the effectiveness among people without overt metabolic disorder. Hypothesis: We assessed the weight loss for people who used the smartphone application with and without personal coaching, with respect to people who did not use any. Methods: A total of 129 participants (aged 30-59 years; 63 men; 66 women) were recru

In the transportation design-build (DB) industry, the responsibility of the design is transferred to the design-build team from the owner. One of the critical issues for state departments of transportation (DOTs) is design professional liability. To cover designers’ professional negligence, design professional liability insurance (DPLI) should ensure satisfactory coverages in DB projects for state DOTs. The objective of this study is to identify the variability of the DPLI policy requirements th

본 연구는 전장유전체 분석(Whole Genome Sequencing, WGS)에서 이차적으로 발견된 의미있는 유전자 결과를 환자에게 고지하는 임상 제도의 도입과 관련된 법적·윤리적 쟁점을 고찰하고, 임상 단계별 권고사항을 도출하는 것을 목적으로 한다. 이차발견은 의료적 유용성을 제공함과 동시에 환자의 심리적 부담, 가족 고지, 개인정보 보호, 취약집단 동의 등 복합적 쟁점을 수반한다. 또한 이차발견 결과 반환 관련 제도화를 위한 법제의 적용가능성을 분석할 필요가 있다. 이를 위하여, 본 연구는 문헌 분석을 통해 이차발견의 개념과 유형을 체계화하고, 비교법적 연구방법을 통해 미국, 유럽 학회 및 영국 보건기관의 권고사항을 중심으로 환자의 자기결정권, 알 권리와 모를 권리의 균형, 미성년자 보호와 관련된 윤리적 쟁점을 검토한다. 또한, 주요 쟁점 별 국내 법령을 비판적으로 분석하여 해결방안을 모색한다. 본 연구는 임상에서 이차발견 유전자 검사 결과를 환자에게 반환하는 절차를 세 단계로
