The prevalence of chronic diseases including osteoporosis and sarcopenia increases as the population ages. Osteoporosis and sarcopenia are commonly associated with genetics, mechanical factors, and hormonal factors and primarily associated with aging. Many older populations, particularly those with frailty, are likely to have concurrent osteoporosis and sarcopenia, further increasing their risk of disease-related complications. Because bones and muscles are closely interconnected by anatomy, metabolic profile, and chemical components, a diagnosis should be considered for both sarcopenia and osteoporosis, which may be treated with optimal therapeutic interventions eliciting pleiotropic effects on both bones and muscles. Exercise training has been recommended as a promising therapeutic strategy to encounter the loss of bone and muscle mass due to osteosarcopenia. To stimulate the osteogenic effects for bone mass accretion, bone tissues must be exposed to mechanical load exceeding those experienced during daily living activities. Of the several exercise training programs, resistance exercise (RE) is known to be highly beneficial for the preservation of bone and muscle mass. This review summarizes the mechanisms of RE for the preservation of bone and muscle mass and supports the clinical evidences for the use of RE as a therapeutic option in osteosarcopenia.

Thyroid hormones play an important physiological role in maintaining adult bone structure and strength. Consequently, thyroid dysfunction is related to skeletal outcomes. Overt hyperthyroidism is an established cause of high bone turnover with accelerated bone loss, leading to osteoporosis and increased fracture risk. Hyperthyroidism induced by thyroid-stimulating hormone-suppressive therapy in patients with differentiated thyroid cancer is a cause of secondary osteoporosis. In contrast, there is a lack of evidence on the negative impact of hypothyroidism on bone health. Considering the clinical updates on the importance of bone health in thyroid dysfunction, the Task Force from the Clinical Practice Guidelines Development Committee of the Korean Thyroid Association recently developed a position statement on the evaluation and management of bone health of patients with thyroid diseases, particularly focused on endogenous hyperthyroidism and thyroid-stimulating hormone-suppressive therapy-associated hyperthyroidism in patients with differentiated thyroid cancer. Herein, we review the Korean Thyroid Association’s position statement on the evaluation and management of bone health associated with thyroid diseases.

OBJECTIVES: As a preliminary study on the prevalence of mental disorders in Korean children and adolescents, we investigated the diagnosis distribution of mental disorders in people under 19 years of age using the health insurance data. METHODS: From the 2011 health insurance data of 1,375,842 people, the data of 286,465 people under 19 years old were extracted. Among them, we selected 10,778 with psychiatric diagnoses; male 6,453 (59.9%) and female 4,325 (40.1%). The frequency of psychiatric diagnoses in the males was 10,140 (62.7%) cases, which was significantly higher than that (6,031; 37.3%) in the females. We categorized the groups into 3 year intervals. RESULTS: In the males under 3 years old, F80 was the most prevalent diagnosis, followed by F98. F90 and F41 were the most prevalent in the 4-15 and above 16 years old groups, respectively. In the females, F98 was the most prevalent in the children up to 3 years old, while F80 was the second most prevalent. In the 4-6 years of age group, F98 was the most prevalent, followed by F93. F90 and F41 were predominant in the 7-12 and above 12 years old groups, respectively. CONCLUSION: In the analysis of the frequency of diagnosis of mental disorders in the population under 19 years old, there were significant differences in the distribution based on age and gender.

The BRAF(V600E) mutation is the most common genetic alteration and presents in 40~80% of all papillary thyroid cancer (PTC), showing the highest prevalence in the Korean population, close to 80%. Previous studies published in the past 10 years showed a significant correlation between BRAF(V600E) mutation and poor prognostic outcomes of PTC, including recurrence and mortality. Therefore, its clinical application for the diagnosis of thyroid nodule or for decisions regarding the management policy by prediction of the prognosis of thyroid cancer has been proposed. However, some recent studies have reported conflict results, and there appear to be growing concerns regard to the cost-benefit of tests for detection of the BRAF(V600E) mutation. In this paper, we reviewed previous studies regarding the BRAF(V600E) mutation and attempted to evaluate the clinical implication of the BRAF(V600E) mutation in clinical practice.

Purpose: Despite advances in diagnostic and imaging technologies, the diagnosis of traumatic hollow viscus injury (HVI) remains a great challenge in clinical practice. This study aimed to determine the accuracy of computed tomography (CT) in the diagnosis of HVI in emergent blunt trauma patients. Methods: The study was conducted on patients with abdominal trauma who were admitted to our center, regional emergency center, Kyung Hee University Medical Center, between January 2008 and December 2018. The clinical data of patients with abdominal trauma who underwent CT and abdominal surgery within 24 hours of hospitalization were analyzed to determine the diagnostic capacity of CT. Results: In total, 156 patients were included in the study. There were 88 cases of blunt trauma. Among these patients, 27 were diagnosed with HVI using CT, and 38 patients were diagnosed with HVI in the operating room. The median injury severity score for these patients was 10.0, the revised trauma score was 7.841, and the trauma injury severity score was 0.96. The sensitivity and specificity of CT in predicting HVI in these patients were 65.8%, and 96.0%, respectively. The positive and negative predictive values were 92.6%, and 78.7%, respectively. Conclusion In urgent situations, CT findings alone are insufficient for diagnosing HVI. Further research on the HVI diagnostic capacity of CT is required.

The objective of the present study was to determine the relationship between serum uric acid (SUA) level and the presence of nonalcoholic fatty liver disease (NAFLD). We analyzed data of 9,019 Koreans who visited a health check up center. The SUA levels of all of these subjects were within the normal range. The participants were divided into 4 groups according to the quartiles of the SUA levels for both sexes. Hepatic steatosis was diagnosed on the basis of ultrasonographic findings. Multivariate logistic regression modeling was performed across the SUA quartiles. The presence of NAFLD and metabolic abnormalities were found significantly in subjects with high-normal SUA levels. After adjustment for age, metabolic components, and the liver-function test, the adjusted odds ratio (OR, 95% CIs) for the presence of NAFLD in the subjects with the highest SUA level was 1.46 (1.17-1.82) for men and 2.13 (1.42-3.18) for women, as compared to the subjects with the lowest SUA level. Our results suggest that increased SUA concentrations, even within the normal range, are independently associated with the presence of NAFLD.

OBJECTIVES: We wanted to investigate the relationship between job stress and liver dysfunction in Korean male white collar workers. METHODS: A total of 700 male white collar workers who worked at one electronic institute and who participated in an annual surveillance program were recruited: 664(94.9%) workers were initially recruited and the data for 36 workers was excluded due to poor responses and a past history of liver disease. The questionnaire survey included the participants' general characteristics, the job-related factors, the health-related behaviors and job stress. Job stress was assessed using the Korean Occupational Stress Scale-Short Form (KOSS-SF). We merged the job stress data with the individual liver function results by conducting annual surveillance. Multiple logistic regression analysis with adjusting it for the confounding variables, including alcohol drinking and the body mass index (BMI), was used to evaluate the relationship between job stress and liver dysfunction. RESULTS: After adjustment for the confounding variables, the proportion of liver dysfunction cases was significantly higher in the groups with a high level of job stress, as assessed by the 'job demands and total score'. After conducting a stratified analysis with considering alcohol drinking and the BMI, the prevalence odds ratio of liver dysfunction was higher in the groups with a high level of job stress, as assessed by the 'job demands and total score'. CONCLUSIONS: The results of this study suggest that the level of job stress (and especially that assessed by the job demands and total score) is related to liver dysfunction. Thus, further preventive efforts and studies are needed to reduce job stress and address liver dysfunction.
