This study compared the prevalence of metabolic syndrome (MetS), its risk factors, and obesity in adolescents in the United States (US) and Korea. Data were obtained from 2003-2004 US National Health and Nutrition Examination Survey (NHANES) and 2005 Korea NHANES for adolescents aged 12-19 yr in the US (n=734) and in Korea (n=664). The 2007 International Diabetes Federation (IDF) pediatric definition for diagnosis of MetS and the 2000 US Growth Charts and 2007 Korea Growth Charts for assessment

AIM: The aim of this study was to evaluate the accuracy of the clock drawing test and to compare its scoring methods. BACKGROUND: Dementia refers to a symptom where an adult demonstrates memory disorder and cognitive impairment. Early diagnosis of dementia is very important for medication management and prognosis. The clock drawing test is one of the most used cognitive screening tools for dementia. However, due to its scoring system, the accuracy of the clock drawing test remains a topic of deb

BACKGROUND: Extremely low frequency magnetic fields (ELF-MFs) are classified as a possible carcinogenic factor (Group 2B). This study assessed the association between ELF-MFs and childhood cancer through a systematic review and meta-analysis. METHODS: Three databases were searched in January 2020. We conducted a meta-analysis for the association between the ELF-MFs exposure level and childhood cancer. RESULTS: A total of 33 studies were identified. Thirty studies with 186,223 participants were i

Large scale for small size: We report a large-scale synthetic method to produce uniform and ultra-small-sized Ag nanoparticles (see picture) with good productivity. This method is simple and efficient. It produces Ag nanoparticles within 20 min by heating a reaction mixture containing only three chemicals. The size of the nanoparticles is controlled by varying the heating rate. Detailed facts of importance to specialist readers are published as ”Supporting Information”. Such documents are peer-r

Precise control over the size and shape of ice crystals is a key factor to consider in designing antifreezing and cryoprotecting molecules for cryopreservation of cells. Here, we report that a poly(ethylene glycol)-poly(l-alanine) (PEG-PA) block copolymer exhibits excellent cryoprotecting properties for stem cells and antifreezing properties for water. As the molecular weight of PA increased from 500, 760, and 1750 Da (P1, P2, and P3) at the same PEG molecular weight of 5000 Da, the β-sheet cont

Major depressive disorder in adolescents is closely linked to poor social, cognitive, and academic outcomes, including suicidality. The Beck Depression Inventory (BDI), a screening tool, is one of the most widely used instruments for detecting depression; however, its diagnostic test accuracy has not yet been thoroughly examined. This study, therefore, aimed to systematically review and perform a meta-analysis to evaluate the accuracy of the BDI for detecting depression in adolescents. In August

Phase-III vaccine efficacy trials typically employ individually randomized designs intended to ensure that measurements of vaccine protective efficacy reflect only direct vaccine effects. As a result, decisions about introducing newly licensed vaccines into public health programmes often fail to consider the substantially greater protection that may occur when a vaccine is deployed in public health programmes, due to the combination of direct plus indirect vaccine protective effects. Vaccine tot

Nurses are the most important health care personnel for medication safety. A scale to measure nurse medication competency, such as the Medication Safety Competence Scale (MSCS), would move research forward. Preliminary items were developed through a literature review and in-depth interviews. Content validity was established by ten experts. Nurses (n = 607) participated in a survey to evaluate the validity and reliability of the scale. Exploratory and confirmatory factor analyses and correlation

This study estimated and compared the prevalence of the Metabolic Syndrome and its individual components in young adults (ages 20-39 years) in the US and Korea using 2003-2004 US and 2005 Korean National Health and Nutrition Examination Survey data. The mean body mass index and rate of metabolic abnormalities in the US were significantly higher than in Korea. The prevalence of the Metabolic Syndrome in the US was nearly three times higher than in Korea using National Cholesterol Education Progra

Delirium is a reversible impairment of metabolism in the human brain. Early detection is important, and an effective screening tool for nurses is crucial. The Delirium Observation Screening (DOS) scale is one such screening tool; however, its diagnostic test accuracy has not yet been thoroughly examined. This study, therefore, aimed to evaluate the accuracy of the scale through a systematic review and meta-analysis. In July 2019, a search was conducted in the MEDLINE, CINAHL, Embase, and PsycART

We synthesized a series of [( l -Ala) x - co -( l -Thr succinate) y ] (PATs), which are analogous to natural antifreezing glycoprotein with the structure of [ l -Ala- l -Ala- l -Thr disaccharide] n, by varying the composition and degree of succinylation while fixing their molecular weight ( M n ) and Ala/Thr ratio at approximately 10–12 kDa and 2:1, respectively. We investigated their ice recrystallization inhibition (IRI), ice nucleation inhibition (INI), dynamic ice shaping (DIS), thermal hyst

This paper explores the history of the biomedical construction of women's bodies as social bodies in the formation of colonial modernity in Korea. To do so, I engage with Michel Foucault's concepts of governmentality and biopolitics and the postcolonial history of medicine that has critically revisited these Foucauldian notions. These offer critical insights into the modern calculation of population and the biomedical gaze on female bodies on the Korean Peninsula under Japan's colonial rule (191
