Purpose: This study aimed to examine the medicating effect of resilience on the relationship between academic burnout and psychological well-being of medical students. Methods: The participants were a group of 97 medical students. Scales measuring Maslach Burnout Inventory-Student Survey, Ryff’s Psychological Well-Being, and Korean Resilience Quotient-53 were utilized. The data were analyzed by descriptive statistics, correlation analysis, t-test, and multiple regression analyses using IBM SPSS ver. 22.0 (IBM Corp., Armonk, USA). Results: According to the study results, the medical students’ psychological well-being was negatively correlated with their academic burnout and positively correlated with their resilience; the degree of academic burnout experienced by the first and second year preclinical students was greater than that experienced by the third and fourth year clinical students; the male students’ average score for cynicism was higher than that of the female students; and the significant effects of academic burnout on the medical students’ psychological well-being were mediated by resilience. Conclusion It was confirmed that medical students’ academic burnout and resilience are significant factors that explain their psychological well-being; resilience is also an important variable in improving psychological well-being. This suggests that education and counseling support are needed to increase medical students’ resilience in order to increase their psychological well-being.

Two miniature Schnauzer dogs with chronic pancreatitis were investigated. Both dogs showed systemic hypertension and increased concentrations of triglycerides and C-reactive protein. Abdominal radiography revealed cylindrical calcification in the retroperitoneum, and computed tomography (CT) showed extensive calcification of the abdominal and peripheral arteries in both dogs. Metastases and other dystrophic conditions that can cause arterial calcification were excluded based on the laboratory tests, and the dogs were diagnosed with atherosclerosis ante mortem. Atherosclerosis should be considered when extensive arterial calcification is observed on abdominal radiography or CT in miniature Schnauzers.

Purpose: The COVID-19 (coronavirus disease 2019) pandemic led to significant changes in clinical clerkships, including reduced ward rounds. We aimed to determine how the pandemic–induced changes in the clinical practice environment affect the clinical performance of medical students. Methods: We analyzed objective structured clinical examination scores of third- and fourth-year medical students from 2019–2020 and 2020–2021 across six stations by the Seoul–Gyeonggi Consortium. Clinical, communication, and ability scores were measured and analyzed using repeated-measures multivariate analysis of variance. Results: The interaction between clinical practice progress and pandemic-induced changes significantly affected physical examination and medical history scores, though the differences were not substantial. Patient-physician interaction significance varied by measurement period. Clinical communication ability also showed significant differences based on the measurement period and practical experience. Conclusion During the pandemic, alternative learning methods, including self–learning, simulation/practice, and peer role–play, helped improve medical competency in areas such as history–taking and physical examination. However, these were less effective in improving patient–physician interactions or clinical communication efficacy. Alternative learning methods have limitations, and they cannot replace direct patient encounters in clinical practice.

The objectives of this study were to investigate the status of vitamin D in Korean adolescents and to determine the association between serum 25-hydroxyvitamin D (25(OH)D) concentration and consumption frequencies of vitamin D food sources by season (June to November and December to May). The subjects were 1,579 adolescents aged 12-18 years participating in the 2008-2009 Korean National Health and Nutrition Examination Survey (KNHANES). Consumption frequencies of vitamin D food sources were estimated by using a qualitative food frequency questionnaire (FFQ). Thirteen food items were selected as vitamin D food sources including beef, egg, mackerel, tuna, yellow corvine, pollack, anchovy, mushroom, milk, yoghurt, ice cream, all fish and dairy products from the FFQ based on previous research. The data was analyzed using proc survey procedures. The deficiency (5.25-12 ng/mL), inadequacy (12-20 ng/mL) and sufficiency (> 20 ng/mL) proportions of serum 25(OH)D from June to November and December to May were 9.9%, 51.4%, 38.7%, and 39.4%, 51.4%, 9.2%, respectively. Mean serum 25(OH)D concentration was positively related to the consumption frequencies of mackerel, anchovy, all fish and milk. These results suggest high proportion (> 61%) of Korean adolescents were vitamin D deficiency or inadequacy, and serum 25(OH)D was associated with the consumption of vitamin D food sources including fish and milk.

OBJECTIVES: This study was conducted to investigate the vitamin D status and to determine the association between serum 25-hydroxyvitamin D [25(OH)D] concentrations and consumption frequencies of vitamin D rich foods in Korean adults and older adults. METHODS: Subjects were 10,374 adults and 2,792 older adults participating in the 2008-2009 Korea National Health and Nutrition Examination Survey (KNHANES). Consumption frequencies of vitamin D rich foods were estimated by using a qualitative food frequency questionnaire (FFQ). Eleven food items such as beef, egg, mackerel, tuna, yellow corvina, pollack, anchovy, mushroom, milk, yogurt, and ice cream were selected as vitamin D rich foods based on previous research. RESULTS: The proportions of deficiency (< 12 ng/mL), inadequacy (12-20 ng/mL) and sufficiency (> or = 20 ng/mL) of serum 25(OH)D concentrations from June to November and December to May in adults were 8.8%, 42.3%, 48.8%, and 28.2%, 52.8%, 19.1%, respectively. The proportions of deficiency, inadequacy and sufficiency of serum 25 (OH)D concentrations from June to November and December to May in older adults were 10.1%, 32.4%, 57.5%, and 24.1%, 45.4%, 30.5%, respectively. The mean serum 25(OH)D concentrations in adults were positively related to the consumption frequencies of mackerel, anchovy, all fish, milk and milk.dairy products. The mean serum 25(OH)D concentrations in older adults were positively related to the consumption frequencies of yellow corvina and negatively related to the consumption frequencies of ice cream. CONCLUSIONS: Our results suggest that Korean adults were more deficient in serum 25(OH)D concentrations than older adults. The consumption of vitamin D rich foods may affect vitamin D status in Korean adults. Further studies are required to confirm these findings.

Bacillus cereus is a widespread organism in nature and a member of the B. cereus group of catalasepositive, aerobic, spore-forming, Gram-positive bacilli. B. cereus found in blood is often dismissed as a contaminant in the absence of repeated isolation from multiple cultures. Soft tissue and bone infection due to B. cereus have been associated with trauma, intravenous drug use, and an immunocompromised state. We report a very late prosthetic joint infection of the hip joint and consequent bacteremia caused by B. cereus, which occurred 13 years after total hip replacement surgery in the absence of recent trauma or intervention.

Siewert–Kartagener’s syndrome, a type of primary ciliary dyskinesia, is a complex disease comprising situs inversus, rhinosinusitis, and bronchiectasis. Situs inversus totalis is a condition in which all organs in the thoracic and abdominal cavities are reversed.Furthermore, primary ciliary dyskinesia, an autosomal genetic disease, may coexist with situs inversus totalis. Reports on Siewert–Kartagener’s syndrome in veterinary medicine are limited. We report a rare case of primary ciliary dyskinesia with Siewert-Kartagener’s syndrome in a dog, concurrently infected with canine distemper virus and type-2 adenovirus.This case highlights that situs inversus totalis can cause primary ciliary dyskinesia, and concurrent infections are possible.
