ABSTRACT

SUMMARY: COVID-19 has forced anatomists to perform non-face-to-face education using lecture videos. A Korean anatomist has given (white and black) board lectures and distributed lecture videos to the public for many years. This study was to verify the effects of open board lecture videos in the anatomy field. A questionnaire survey was carried out with the help of medical students who were exposed to the board lecture videos. The video provider uploaded the lecture videos on YouTube, where the viewing numbers were counted. At a medical school where the video provider belonged, the students mainly watched the lecture videos before the anatomy class. The watching hours of the lecture videos were related to the written examination scores. Students gave positive and negative comments on the board lectures. At the other two medical schools, students partly watched the lecture videos regardless of the teacher who delivered the lectures. The results suggested that students understood the board lectures themselves. On YouTube, the lecture videos were viewed by approximately 1,000 students. This paper introduces the desirable aspects of open board lecture videos on anatomy. The videos could enhance the quality of both students and teacher.


RESUMEN: COVID-19 ha obligado a los anatomistas a realizar una enseñanza no presencial mediante videos de conferencias. Un anatomista coreano ha impartido conferencias (en blanco y negro) y ha distribuido videos de conferencias al público durante muchos años. El objetivo de este estudio fue verificar los efectos de los videos de conferencias de pizarra abierta en el campo de la anatomía. Se llevó a cabo una encuesta con la ayuda de estudiantes de medicina que habían sido expuestos a los videos de conferencias de la pizarra. El proveedor de videos subió los videos de las conferencias a YouTube, donde se contabilizó el número de visualizaciones. En una facultad de medicina a la que pertenecía el proveedor de videos, los estudiantes vieron principalmente los videos de conferencias antes de la clase de anatomía. Las horas de revisión de los vídeos de las conferencias se relacionaron con las puntuaciones de los exámenes escritos. Los estudiantes dieron comentarios positivos y negativos sobre las conferencias de la pizarra. En las otras dos facultades de medicina, los estudiantes vieron parcialmente los videos de las clases, independientemente del profesor que las impartiera. Los resultados sugerían que los estudiantes entendieron las conferencias de la pizarra por sí mismos. En YouTube, los videos de las conferencias fueron vistos por aproximadamente 1000 estudiantes. Este artículo presenta los aspectos deseables de los videos de conferencias abiertas sobre anatomía. Los videos podrían mejorar la calidad tanto de los estudiantes como del profesor.

ABSTRACT

Resumo: Os estudos publicados sobre a resposta da Coreia do Sul à COVID-19 apontam para distintos motivos para seu êxito. Não foram identificadas revisões sobre a Coreia do Sul entre janeiro de 2020 e abril de 2021 ou que analisassem o recrudescimento da pandemia. Visando melhor sistematização sobre o seu sucesso no controle da epidemia, desenvolveu-se uma revisão integrativa para analisar a experiência daquele país no enfrentamento da pandemia de COVID-19, buscando identificar a relação entre as medidas adotadas, as características do sistema de saúde e a evolução de indicadores selecionados. Utilizaram-se distintas bases de dados, além dos boletins epidemiológicos e conferências de imprensa do Centro Sul-coreano de Prevenção e Controle de Doenças (KCDC). Adicionalmente, analisaram-se relatórios da Organização Mundial da Saúde (OMS), do Observatório Europeu de Políticas e Sistemas de Saúde. Os resultados do presente estudo permitem identificar um conjunto de lições com base na experiência sul-coreana visando o controle e manejo da doença. A resposta da Coreia do Sul foi bem-sucedida devido às ações no controle de riscos e danos, atuação sobre determinantes sociais para mitigar os efeitos socioeconômicos da crise sanitária, a experiência prévia em outras epidemias respiratórias e a coordenação nacional expressiva.

Abstract: The studies published on the South Korean response to COVID-19 point to different reasons for the country's success. No reviews were identified on South Korea from January 2020 to April 2021 or that analyzed the pandemic's recrudescence. Aimed at better systematization of South Korea's success in controlling the epidemic, we conducted an integrative review to analyze that country´s experience with the COVID-19 pandemic, seeking to identify the relationship between the measures adopted, the health system's characteristics, and evolution of the selected indicators. Various databases were used, beside epidemiological bulletins and press conferences of the Korea Centers for Disease Control and Prevention (KCDC). We also analyzed reports by the World Health Organization (WHO) and the European Observatory on Health Systems and Policies. The study's results allow identifying a set of lessons based on the South Korean experience with control and management of the disease. The response by South Korea was successful, due to action in the control of risks and harms, action on social determinants to mitigate the socioeconomic effects of the health crisis, prior experience with other respiratory disease epidemics, and effective national coordination.

ABSTRACT

BACKGROUND@#Nonalcoholic fatty liver disease (NAFLD) is becoming a global health problem. Bisphenol A (BPA), one of most widely used environmental chemicals, is suspected to be a contributor to the development NAFLD. This study was performed to examine the relationship between human BPA levels and risk of NAFLD.@*METHODS@#The data (n = 3476 adults: 1474 men and 2002 women) used in this study were obtained from the Korean National Environmental Health Survey III (2015-2017). BPA levels were measured in urine samples. NAFLD was defined using hepatic steatosis index after exclusion of other causes of hepatic diseases.@*RESULTS@#There was a significant linear relationship between the elevated urinary BPA concentrations and risk of NAFLD. In a univariate analysis, odds ratio (OR) of the highest quartile of urinary BPA level was 1.47 [95% confidence interval (CI) 1.11-1.94] compared to the lowest quartile. After adjusted with covariates, the ORs for NAFLD in the third and fourth quartiles were 1.31 [95% CI 1.03-1.67] and 1.32 [95% CI 1.03-1.70], respectively.@*CONCLUSIONS@#Urinary BPA levels are positively associated with the risk of NAFLD in adults. Further experimental studies are needed to understand the molecular mechanisms of BPA on NAFLD prevalence.

ABSTRACT

BACKGROUND@#An acute upper respiratory tract infection (URI) is the most common disease worldwide, irrespective of age or sex. This study aimed to evaluate the short-term effect of diurnal temperature range (DTR) on emergency room (ER) visits for URI in Seoul, Korea, between 2009 and 2013.@*METHODS@#Daily ER visits for URI were selected from the National Emergency Department Information System, which is a nationwide daily reporting system for ER visits in Korea. URI cases were defined according to International Classification of Diseases, 10@*RESULTS@#There were 529,527 ER visits for URI during the study period, with a daily mean of 290 visits (range, 74-1942 visits). The mean daily DTR was 8.05 °C (range, 1.1-17.6 °C). The cumulative day (lag 02) effect of DTR above 6.57 °C per 1 °C increment was associated with a 1.42% (95% confidence interval [CI] 0.04-2.82) increase in total URI. Children (≤ 5 years of age) were affected by DTR above 6.57 °C per 1 °C, with 1.45% (95% CI 0.32-2.60) at lag 02, adults (19-64 years) with 2.77% (95% CI 0.39-5.20) at lag 07. When the DTR (lag02) was 6.57 °C to 11.03 °C, the relative risk was significant at 6.01% (95% CI 2.45-9.69) for every 1 °C increase in youth subjects aged for 6 to 18 years.@*CONCLUSIONS@#DTR was associated with a higher risk for ER visits for URI. In addition, the results suggested that the lag effects and relative risks of DTR on URI were quite different according to age.

ABSTRACT

BACKGROUND@#One effective way to improve return-to-work (RTW) performance may be to convince the employer that the worker has the necessary skills. The aim of this paper is to investigate the effect of having a professional certification among workers injured in occupational injuries on their return to work.@*METHODS@#The Panel Study of Workers' Compensation Insurance (PSWCI) targets workers who completed medical care in 2012 after an occupational injury. The study population (n = 2000) was stratified by gender, age, region, disability grade, and rehabilitation service use. A total of 1458 workers were finally selected for this study. The effect of having a certification on RTW status was calculated with an odds ratio and 95% confidence intervals using binomial and multinomial logistic regression analyses. In the binomial logistic regression analysis, the RTW group was made up as a combination of the return to original work and the reemployment groups.@*RESULTS@#The ORs of RTW among those with a certification compared to those without certification were 1.38 (1.16-1.65) in Model 1, 1.25 (1.05-1.50) in Model 2, and 1.22 (1.01-1.47) in Model 3. Among female workers with a certification, the OR of RTW was 4.60 (2.68-7.91), that of return to original work was 3.21 (1.74-5.91), and that of reemployment was 5.85 (3.34-10.27). Among daily workers with a certification, the OR of RTW was 1.32 (1.03-1.69) and that of reemployment was 1.37 (1.07-1.76).@*CONCLUSION@#In conclusion, injured workers with a certification generally had a higher RTW rate. In particular, the RTW rate was higher among female workers and daily workers with a certification than among those without.

ABSTRACT

In Southern Medical University, China, 1,200 medical students study neuroanatomy every year, whereas in Ajou University, Korea, only 45 medical students study neuroanatomy. The considerable difference of student numbers results in differences in educational situations. The purpose of this study was to investigate desirable neuroanatomy education methods for large and small numbers of students. The situations of neuroanatomy education in China and Korea were compared systematically. With a questionnaire survey, positive comments and recommendations for their counterparts were collected from the medical students (168 Chinese and 41 Koreans) and anatomists (6 Chinese and 3 Koreans). By reviewing the opinions, the Chinese and Korean anatomists could learn from each other to improve their strong points and make up for the weak points. The results also disclosed the common problems of neuroanatomy education, which could be relieved by developing the fitting book and the self-learning tools, such as lecture videos and stereoscopic computer models.


En la Universidad de Medicina del Sur, China, 1.200 estudiantes de medicina estudian la neuroanatomía cada año, mientras que en la Universidad de Ajou, Corea, solo 45 estudiantes de medicina estudian neuroanatomía. Esta considerable variable del número de estudiantes resulta en diferencias en las situaciones educativas. El propósito de este estudio fue investigar métodos de educación en neuroanatomía deseables para cantidades mayores y menores de estudiantes. Se compararon sistemáticamente las situaciones de educación en neuroanatomía en China y Corea. Por medio de una encuesta por cuestionario, se obtuvieron comentarios positivos y recomendaciones para sus contrapartes de los estudiantes de medicina (168 chinos y 41 coreanos) y anatomistas (6 chinos y 3 coreanos). Al revisar las opiniones, los anatomistas chinos y coreanos podrían aprender unos de otros para mejorar sus puntos de fortaleza y compensar los aspectos débiles. Los resultados también revelaron los problemas comunes de la educación en neuroanatomía, que podrían aliviarse desarrollando el libro de adaptación y las herramientas de autoaprendizaje, como videos de conferencias y modelos de computadora estereoscópica.

ABSTRACT

Abstract Introduction: Age-related hearing impairment is the most common sensory dysfunction in older adults. In osteoporosis, the mass of the ossicles will be decreased, affecting the bone density of the cochlea, and interfering with the sound transmission to the cochlea. Age related hearing loss might be closely related to osteoporosis. Objective: To determine the relationship between age-related hearing impairment and osteoporosis by investigating the relationship between hearing loss and cortical bone density evaluated from femur neck bone mineral density. Methods: We used data from the Korea National Health and Nutrition Examination Survey to examine the associations between osteoporosis and age-related hearing impairment from 2009 to 2011. Total number of participants was 4861 including 2273 men and 2588 women aged 50 years or older. Osteoporosis was defined as a bone mineral density 2.5 standard deviations below according to the World Health Organization diagnostic classification. Age-related hearing impairment was defined as the pure-tone averages of test frequencies 0.5, 1, 2, and 4 kHz at a threshold of 40 dB or higher on the more impaired hearing side. Results: Total femur T-score (p < 0.001), lumbar-spine T-score (p < 0.001) and, femur neck T-score (p < 0.001) were significantly lower in the osteoporosis group compared to the normal group. Thresholds of pure-tone averages were significantly different in normal compared to osteopenia, and osteoporosis groups. In addition, there were significantly higher pure-tone averages thresholds in the osteoporosis group compared to other groups (p < 0.001). After adjusting for all covariates, the odds ratio for hearing loss was significantly increased by 1.7 fold with reduced femur neck bone mineral density (p < 0.01). However, lumbar spine bone mineral density was not statistically associated with hearing loss (p = 0.22). Conclusion: Our results suggest that osteoporosis is significantly associated with a risk of hearing loss. In addition, femur neck bone mineral density was significantly correlated with hearing loss, but lumbar spine bone mineral density was not.


Resumo Introdução: A perda auditiva associada ao envelhecimento é a disfunção sensorial mais comum em idosos. Na osteoporose, a massa dos ossículos diminui e afeta a densidade óssea da cóclea, o que irá interferir na transmissão do som para a mesma. A perda auditiva associada à idade pode estar intimamente relacionada à osteoporose. Objetivo: Determinar a relação entre deficiência auditiva relacionada à idade e osteoporose, investigar a relação entre perda auditiva e densidade óssea cortical avaliada a partir da densidade mineral óssea do colo do fêmur. Método: Utilizamos dados da Korea National Health and Nutrition Examination Survey para examinar as associações entre osteoporose e perda auditiva associada ao envelhecimento de 2009 a 2011. O número total de participantes foi de 4.861, incluiu 2.273 homens e 2.588 mulheres com 50 anos ou mais. A osteoporose foi definida como densidade mineral óssea com 2,5 desvios-padrão abaixo da média, de acordo com a classificação diagnóstica da Organização Mundial da Saúde. A perda auditiva associada ao envelhecimento foi definida como as médias de tom puro das frequências de teste de 0,5, 1, 2 e 4 kHz a um limiar de 40 dB ou superior no lado da audição mais afetado. Resultados: O T-score total do fêmur (p < 0,001), o T-score da coluna lombar (p < 0,001) e o T-score do colo do fêmur (p < 0,001) foram significantemente menores no grupo com osteoporose em comparação ao grupo normal. Os limiares de médias de tom puro foram significantemente diferentes nos grupos normais em comparação com aqueles com osteopenia e osteoporose. Além disso, houve limiares significantemente maiores de médias de tom puro no grupo com osteoporose em comparação com os outros grupos (p < 0,001). Após o ajuste para todas as covariáveis, a odds ratio da perda auditiva mostrou estar significantemente aumentada em 1,7 vez com densidade mineral óssea reduzida no colo do fêmur (p < 0,01). No entanto, a densidade mineral óssea da coluna L não se associou estatisticamente à perda auditiva (p = 0,22). Conclusão: Nossos resultados sugerem que a osteoporose está significantemente associada ao risco de perda auditiva. Além disso, a densidade mineral óssea da coluna lombar não se correlacionou com a perda auditiva, apenas a densidade mineral óssea do colo do fêmur foi significantemente correlacionada.

ABSTRACT

ABSTRACT Objectives The aim of this study was to evaluate the association between nutritional intake and metabolic syndrome in otherwise healthy middle-aged Korean women. Subjects and methods Retrospectively, medical records were reviewed for nutritional intake of 2,182 Korean women who had undergone routine medical check-ups from 2010 to 2016 at Pusan National University Hospital. The patients who met diagnostic criteria for metabolic syndrome based on NCEP-ATPIII were included, and each of the patients was assessed through self-report questionnaires and individual interview with a health care provider. The recommended dietary allowance (RDA) for women in Republic of Korea was based on 2015 criteria discussed in Dietary Reference Intake for Koreans, organized by the Ministry of Health and Welfare. Results Through univariate analysis, daily calorie, protein, fat, and carbohydrate consumption were significantly higher and exceeded RDA in the patients with metabolic syndrome; other than major nutrients, iron, vitamin B2, and niacin were also consumed in excess of the RDA in these patients. Multivariate analysis showed that carbohydrate consumption, along with protein and vitamin B2, were significantly higher in the patients with metabolic syndrome. Conclusion In middle-aged Korean women, high consumption of carbohydrates, along with protein and vitamin B2, was found to have a statistically significant association with the presence of metabolic syndrome.

ABSTRACT

PURPOSE: To report a case of corneal collagen cross-linking for corneal ulcer caused by the Moraxella group.CASE SUMMARY: A 77-year-old male had decreased visual acuity for several days in his right eye. The patient showed severe stromal ring infiltrates with a corneal epithelial defect measuring (5.0 × 7.0 mm), a corneal endothelial plaque, and a hypopyon measuring less than 1.0 mm in height in the anterior chamber of the right eye. There was no abnormal finding in the right eye using B-scan ultrasonography. Before starting treatment, a corneal culture was conducted. The culture tests showed the presence of the Moraxella group. Because the patient was diagnosed with a corneal ulcer caused by the Moraxella group, corneal collagen cross-linking (CXL) was performed. The antimicrobial susceptibility test confirmed that this Moraxella group was sensitive to ceftazidime, so the patient was treated with 5% ceftazidime eye drops and 0.5% moxifloxacin eye drops every 2 hours for 9 months after corneal collagen CXL. The uncorrected visual acuity was 0.1 in the right eye, and there was almost no corneal stromal melting on anterior segment optical coherence tomography.CONCLUSIONS: This is the first known case of a corneal ulcer, in the Republic of Korea, caused by the Moraxella group and treated with corneal collagen CXL. Corneal collagen CXL should be considered as a surgical treatment for patients who have an impending corneal perforation due to a corneal ulcer because it is a simple procedure and causes fewer serious complications than other treatments.

ABSTRACT

PURPOSE: We determined whether elevated serum alkaline phosphatase (ALP) was related to prevalence, location, type, length, and recurrence of pterygium in a population from the Republic of Korea.METHODS: A nationwide cross-sectional dataset, the Korean National Health and Nutrition Examination Survey (2008–2011), was used in this study. All participants were > 30 years of age and underwent the ALP test and ophthalmic evaluation (n = 22,359). One-way analysis of variance, the chi-square test, and Fisher's exact test were used to compare characteristics and outcomes among participants. Multivariable logistic regression was used to examine the possible associations between serum ALP levels and various types of pterygium. Data were adjusted for known risk factors for development of pterygium and ALP elevation (age, sex, residence, sunlight exposure, drinking, smoking, hypertension, diabetes, BMI, AST, ALT, vitamin D, and HDL).RESULTS: The overall prevalence of pterygium was 8.1%, and participants with pterygium had higher levels of serum ALP (p < 0.001). Participants with higher serum ALP had a significantly higher prevalence of all types of pterygium than those in the lower serum ALP quartiles. After adjusting for potential confounding factors, multivariate logistic regression analysis revealed that ALP was associated with the prevalence of pterygium (odds ratio [OR], 1.001; p = 0.038). Trend analysis between the OR and ALP quartiles revealed a linear trend in overall prevalence and in the intermediate type of pterygium. Subgroup analysis revealed a stronger correlation in participants > 50 years of age. One-way analysis of variance revealed an association between the size of pterygium and serum ALP quartile levels. Serum ALP was not associated with recurrence of pterygium.CONCLUSIONS: Increased serum ALP was associated with the prevalence and size of pterygium.

ABSTRACT

@#<![CDATA[Mumps is contagious disease and maintaining immunity to mumps in healthcare worker (HCW) is important for preventing transmission in the hospital. We evaluated the seroprevalence of mumps in HCWs in a tertiary care hospital in Republic of Korea. A total of 6,055 HCWs born between 1950 and 1995 underwent antibody testing. The overall seropositivity rate of mumps was 87% (95% confidence interval, 86%–87%). Our data indicates that, in Korean HCWs, testing for mumps antibody followed by mumps vaccination is more appropriate than routine mumps vaccination without testing for mumps antibody.]]>

ABSTRACT

OBJECTIVE@#To investigate the effect of hydrogen-rich Korean Red Ginseng (KRG) water (HRGW) mixture on the spermatogenesis and sperm motility of mice of different ages.@*METHODS@#Eighty young (3 month-old) and aged (12 month-old) male mice were randomly assigned to 4 groups (n =10 per group) including control group, hydrogen-rich water (HRW) group (10 mL/kg daily), KRG group (50 mg/kg daily) and HRGW group (10 mL/kg and 50 mg/kg daily) by an oral zoned needle for 4 weeks. Sperm count and motility were measured using sperm suspension released from cauda epididymis. Serum follicle stimulating hormone (FSH), luteinizing hormone (LH), testosterone, and reactive oxygen species (ROS) in serum have also been estimated. Tubular changes were examined through histological hematoxylin and eosin staining. Expression of antioxidation (PPx3, PPx4, GSTm5 and GPx4), spermatogenesis (inhibin-a, neptin-2 and CREM), antiaging (SIRT1 and SIRT2), and angiogenesis [visfatin and vascular endothelial growth factor (VEGF)] related genes were examined through real-time polymerase chain reaction.@*RESULTS@#HRW and KRG treatment stimulated spermatogenesis followed by increasing sperm production and sperm motility (P <0.05). These effects were strengthened synergistically by a HRGW mixture (P <0.05 or P <0.01). HRGW greatly increased the expressions of antioxidation, antiaging, spermatogenesis related genes and VEGF especially in aged mice (P <0.05). Serum testosterone and FSH levels also increased, while serum ROS level decreased (all P <0.05).@*CONCLUSION@#HRGW increases sperm production and motility by enhancing antioxidation and stimulating spermatogenesis and sex hormone production, particularly in aged mice.

ABSTRACT

BACKGROUND@#This study aims to understand the extent of adolescents' attempts to quit using tobacco and the factors influencing such attempts in Korea, using a descriptive, cross-sectional design and secondary data analysis with the 2019 Youth Health Behavior Survey.@*METHODS@#The participants were 4028 adolescent tobacco users who had used tobacco for 1 day or more in the past 30 days. The data analysis was performed using IBM SPSS/WIN 26.0 program, and multivariable logistic regression analysis was conducted using the complex sampling method module.@*RESULTS@#A total of 68.2% of the participants attempted to quit using tobacco. We analyzed the factors for adolescents' attempts to quit using tobacco by dividing them into psychological, physical, behavioral, and environmental dimensions. The factors influencing adolescents' attempts to quit using tobacco, identified through multivariable logistic regression analysis, are as follows: participation in sports activities (OR = 1.20, 95% CI 1.01-1.41), vigorous physical activity (OR = 1.24, 95% CI 1.06-1.46), and type of tobacco product used (OR = 1.65, 95% CI 1.24-2.21) in the behavioral dimension; pictorial cigarette pack warnings (perceived smoking as unhealthy) (OR = 1.91, 95% CI 1.56-2.36), and the presence of secondhand smoking at home (OR = 1.18, 95% CI 1.01-1.38) in the environmental dimension.@*CONCLUSIONS@#Schools and public healthcare providers must consider multidimensional factors when providing support for successful tobacco cessation in adolescents and focus particularly on elements relating to physical activity and environmental factors.
