Discussion on the Clinical Course of Adverse Effects after COVID-19 Vaccination: A Retrospective Analysis of Case Series in an Outpatient Department.

Background: A total of 8,303 individuals (4.3%) with adverse reactions (n=191,860) after vaccination developed serious conditions or died. Such health developments could cause people not vaccinated yet or waiting for a booster shot to become fearful of the vaccination.

Smoking and Diabetes as Predictive Factors of Accelerated Loss of Muscle Mass in Middle-Aged and Older Women: A Six-Year Retrospective Cohort Study.

Preservation of muscle mass during aging reduces the risk of frailty and age-related chronic diseases. We investigated the lifestyle, psychological factors, and common cardiometabolic diseases associated with accelerated muscle loss in middle-aged and older women. A total of 881 women aged 40 years and older who underwent regular health checkup at a tertiary care hospital in Korea in 2010-2011 and underwent a 6-year follow-up were included in this study.

Association of Lung Function with Serum 25-Hydroxyvitamin D Level according to the Presence of Past Pulmonary Tuberculosis in Korean Adults.

Background: Vitamin D deficiency is associated with an increased risk of pulmonary tuberculosis (PTB) infection and the treatment outcome. The aim of this study was to examine the relationship between the serum 25-hydroxyvitamin D (25[OH]D) level and lung function in Korean adults according to whether or not there is a history of PTB.

Methods: The data for subjects aged 19 years or older from the Korea National Health and Nutrition Examination Survey 2008-2012 who underwent spirometry, chest radiography, and serum 25(OH)D level measurement were analyzed.

Risk of Sarcopenia and Osteoporosis in Male Tuberculosis Survivors: Korea National Health and Nutrition Examination Survey.

Short-term prospective studies have suggested that pulmonary tuberculosis (TB) preludes permanent loss of lean tissue and fat mass even when TB treatment is effective. The aim of this study was to estimate the risk of sarcopenia and osteoporosis among Korean male TB survivors. Data of the population-based, Korea National Health and Nutrition Examination Survey (KNHANES) (2008-2011) were analyzed, including 3,228 males aged 50 years or older who underwent chest X-ray (CXR) and dual-energy x-ray absorptiometry (DEXA).

The Definition of Past Tuberculosis Affects the Magnitude of Association between Pulmonary Tuberculosis and Respiratory Dysfunction: Korea National Health and Nutrition Examination Survey, 2008-2012.

Tuberculosis (TB) is associated with an increased risk of chronic lung impairment. The aim of this study was to compare the clinical characteristics and lung functions according to definition of past TB. We used the population-based, Korea National Health and Nutrition Examination Survey (KNHANES) (2008-2012) to analyze 13,522 subjects age 40 years or older who underwent spirometry and chest X-ray (CXR).

Medical students' and patients' perceptions of patient-centred attitude.

Purpose: Patient-centred care can increase patient satisfaction and lead to better clinical outcomes for them, such as improved physical status and higher health-related quality of life. However, doctors' and patients' views on patient-centred attitude might differ and could be affected by culture and the community environment. To clarify the differences in primary care patients' and senior medical students' perceptions of medical students' patient-centred attitude.

Changes in medical students' patient-centeredness attitudes by implementation of clinical performance examination.

Purpose: From 2009, the Korean Medical Licensure Exam implemented a clinical performance examination (CPX) that highlighted the importance of good patient-physician relationships in medical education. This study aimed to examine changes in medical students' attitudes before and after implementation of the CPX in their medical education curriculum.

Methods: In 2006 and 2009, 236 fourth-year medial students of C College of Medicine took the Patient Practitioner Orientation Scale (PPOS) by Krupet et al.

Changes in the degree of patient expectations for patient-centered care in a primary care setting.

Background: To date, the medical environment has been undergoing continual changes. It is therefore imperative that clinicians recognize the changing trends in the degree of patient expectations for patient-centered care. We conducted this study to examine changes in the degree of patient expectations for patient-centered care and the related socio-demographic factors in a primary care setting over a 5-year period.

Relationship between breast-feeding and bone mineral density among Korean women in the 2010 Korea National Health and Nutrition Examination Survey.

Breast-feeding has the deleterious effect of hypoestrogenemia coupled with loss of calcium in the maternal bone mass. It is not clear whether changes in bone metabolism in lactating women lead to changes in maternal bone mineral density (BMD) over a longer period. The aim of the present study was to investigate the relationship between the duration of breast-feeding and BMD in healthy South Korean women.

Relationship between serum 25-hydroxyvitamin D and lung function among Korean adults in Korea National Health and Nutrition Examination Survey (KNHANES), 2008-2010.

Context: The relationship between vitamin D status and pulmonary function has not been investigated for an East Asian population.

Objective: The aim of the present study was to examine the relationship of serum 25-hydroxyvitamin D [25(OH)D] with lung function in Korean adults.

Design And Setting: The analysis used data from the Korea National Health and Nutrition Examination Survey (KNHANES), a cross-sectional survey of Korean civilians, conducted from 2008 to 2010.

Reactivity of heart rate variability after exposure to colored lights in healthy adults with symptoms of anxiety and depression.

Studies on human psychological domains associated with color specific light effects have been reported. The heart rate variability (HRV) has been suggested to be a useful tool for the detection of short-term effects of light on the autonomic nervous system (ANS). The emotional state of an individual has an independent effect on the HRV.

Extraintestinal migration of Centrorhynchus sp. (Acanthocephala: Centrorhynchidae) in experimentally infected rats.

Reptiles were known to serve as paratenic hosts for Centrorhynchus (Acanthocephala: Centrorhynchidae) in Korea, but the infection course in experimental animals was not elucidated yet. In this study, the tiger keelback snakes (Rhabdophis tigrinus) were collected and digested with artificial pepsin solution, and the larvae of Centrorhynchus were recovered from them. Then, the collected larvae were orally infected to rats for developmental observations.

Are medical students satisfied with their medical professionalism education?

Purpose: This study aims to examine the satisfaction of undergraduate medical students with their medical professionalism education.

Methods: Two hundred and one premedical students and 1,287 medical students (from year 1 to 4) participated in a five-point Likert scale survey. There were 27 items in the premedical students' survey and 31 items in the medical students' questionnaire.

To compare the efficacy and safety of nifedipine sustained release with Ginkgo biloba extract to treat patients with primary Raynaud's phenomenon in South Korea; Korean Raynaud study (KOARA study).

This study examined the efficacy and safety of nifedipine sustained release (nifedipine SR) compared with Ginkgo biloba extract as treatment for primary Raynaud's phenomenon (RP) in Korea. Primary RP were screened and assigned to either the nifedipine SR group (Group N) or the Ginkgo biloba extract group (Group G) in the ratio of 2:1. After a run-in period of 2 weeks, patients received treatment for 8 weeks.

Cut-off values of visceral fat area and waist circumference: diagnostic criteria for abdominal obesity in a Korean population.

The aim of this study was to determine the appropriate cut-off values for visceral fat area and waist circumference (WC) associated with an increase in risk for obesity-related disorder, and to validate diagnostic criteria for abdominal obesity and the metabolic syndrome in a Korean adult population. We included 413 subjects (174 men and 239 women) for this study. Subjects were selected among Korean adults who visited the obesity clinic at St.
