Background:
F-18-fluorodeoxyglucose positron emission tomography (FDG-PET)/computed tomography (CT) can be used to measure bone mineral density (BMD), cross-sectional muscle area (CSMA), Hounsfield units (HU) of liver and muscle, subcutaneous adipose tissue (SAT), abdominal visceral adipose tissue (VAT), and glucose metabolism. The present study aimed to identify age-related changes in body composition and glucose metabolism in Korean using opportunistic FDG-PET/CT imaging.
Methods:
We analyzed FDG-PET/CT, clinical history, and laboratory data abstracted from the medical records of patients who underwent health screening at a single institute between 2017 and 2022.
Results:
In total, 278 patients were included in the analysis (male:female=140:138). Age and body mass index were positively correlated in female, but negatively correlated in male. BMD decreased with age more in female, and CSMA decreased with age more in male. Muscle HU decreased with age for both sexes. In female, SAT and VAT increased with age; and in male, SAT decreased slightly while VAT remained stable. Muscle glucose metabolism showed no association with age in male but increased with age in female. CSMA correlated positively with BMD overall; and positively correlated with VAT and SAT in male only. In female only, both SAT and VAT showed negative correlations with glucose metabolism and correlated positively with muscle glucose metabolism. Liver HU values were inversely correlated with VAT, especially in female; and positively correlated with muscle glucose metabolism in female only.
Conclusion
FDG-PET/CT demonstrated distinct patterns of age-related changes in body composition and glucose metabolism, with significant differences between sexes.

PURPOSE: The purpose of this study was to develop and implement the Hospice Smart Patient Program and to evaluate its effectiveness. METHODS: It was quasi-experimental non-equivalent pre-post study. Breast cancer patients who underwent surgery, chemotherapy or radiotherapy, or who needed palliative care, participated in the study. Participants were divided into two groups, experimental and control groups based on their preferences. The program was developed after literature review and discussion among experts on hospice and palliative care. Participants who were in the experimental group received either face-to-face or phone "Hospice Smart Patient" Service at least once a week for 5 months. RESULTS: There was a significant difference in quality of life and communication skill between the two groups after the service was provided. In addition, participants in experimental group showed improved decision making skills, mastery sense, and understanding of hospice and palliative care, which would be beneficial in improving their quality of life. CONCLUSION: We have concluded that the "Hospice Smart Patient" Program is useful for cancer patients in decision making, improving self-control and choosing hospice care to improve their quality of life.

OBJECTIVE: The purpose of this study was to investigate physical and ultrasonographic (US) imaging findings in pain-free shoulders of high school baseball players. METHOD: Physical examination including range of motion (ROM) and several pain provocative tests and US examination on both shoulders in forty-one high school baseball players were performed. The findings of these examinations were classified according to the dominance of shoulders and position of the players and described. RESULTS: Neer, Jobe, Hawkins test, and acromioclavicular tenderness were positive in 33.3%, 4.8%, 28.6%, and 38.3% respectively. Dominant shoulders had larger ROM of external rotation and internal rotation than non-dominant shoulders (p <0.05). Dominant shoulders of pitchers group had larger ROM of external rotation and smaller ROM of internal rotation than those of non-pitchers group (p <0.05). Dominant supraspinatus tendons of pitchers group were thicker than those of non-pitchers group (p <0.05). CONCLUSION: About one third of pain-free shoulders of baseball players showed positive in pain provocative tests. There were several differences in shoulder ROM and ultrasonographic thickness of supraspinatus tendon according to the dominance of shoulders and position of players.

BACKGROUND/AIMS: The changes in an Electrogastrography (EGG) in uremic patients on maintenance hemodialysis with dyspeptic complaints are not well known. The aim of this study was to investigate the EGG findings in uremic patients with dyspeptic complaints and note the difference of EGG findings between uremic patients with dyspeptic complaints and patients with functional dyspepsia. METHODS: Fifty two subjects were enrolled. They were assigned to: group I, healthy volunteers without dyspeptic complaints (n=15); group II, patients with dysmotility-like dyspepsia (n=22); or group III, uremic patients undergoing hemodialysis with dysmotility-like dyspepsia (n=15). The data was compared among groups. RESULTS: There was no difference in the percentage of normal slow wave frequency, and fed to fasting power ratio among the groups. However, frequencies of abnormal EGG findings were 4 (27%) in group I, 10 (40%) group II and 9 (60%) in group III. Therefore the frequency was marginally different among group I, group II or group III (p=0.06). CONCLUSIONS: Impaired gastric myoelectric activity was more frequently observed in uremic patients or patients with dysmotility-like dyspepsia than normal controls. However frequencies of abnormal EGG findings between uremic patients and patients with dysmotility-like dyspepsia were not significantly different.

Journal of the Korean Academy of Child and Adolescent Psychiatry 2021;32(3):104-111
Objectives:
Adolescent suicide is a serious national issue in Korea. Recently, life satisfaction has been recognized as a major factor related to this issue. The main purpose of this study was to identify the domains of life satisfaction that affect suicidal behavior in adolescence.
Methods:
Data were collected from eight middle schools in Incheon, Korea. A total of 1297 students answered questions regarding their demographic characteristics, happiness, self-related life satisfaction domains (appearance, leisure time, physical health, and mental health), depressive symptoms, and suicidal behavior.
Results:
In the Spearman correlation analysis, female sex, perceived socioeconomic status (SES), happiness, and all four self-related satisfaction scores showed significant correlations with depression and suicidality. Multivariate regression analysis suggested that suicidality was significantly affected by perceived SES, satisfaction with appearance, mental health satisfaction, and depression. Finally, depression was identified as a partial mediator of the association between mental health satisfaction and suicidality, and a complete mediator of the association between female sex and suicidality.
Conclusion
Perceived SES, satisfaction with appearance, and mental health satisfaction significantly affected students’ suicidality, with or without the effect of depression. Health authorities, educators, and family members must be aware of this to identify adolescents at suicide risk earlier.

Journal of the Korean Society of Biological Psychiatry 2020;27(2):84-93
Objectives:
The purpose of the present study was to examine the relationship between the chronotype and the burnout, so we investigated the mediating effects of the mediators such as perceived stress, stress response, and depression.
Methods:
Employees working at Incheon Customs conducted a mental health self-examination through the internet. Among them, 174 people who agreed to the mental health survey participated in the study. Participants completed questionnaires including Composite Scale of Morningness (CSM), Center for Epidemiological Studies-Depression Scale (CES-D), Perceived Stress Scale (PSS), Stress Response Inventory (SRI), Maslach Burnout Inventory-General Survey (MBI-GS).
Results:
Our results showed a higher degree of CES-D, SRI, exhaustion, and cynicism in evening and intermediate type compared to morning type, and a higher degree of professional efficacy in morning type compared to intermediate type. CSM was shown to have a direct effect on exhaustion and indirect effect through CES-D and SRI. CSM also had a direct effect on professional efficacy and had an indirect effect through the CES-D. However, CSM was found to have only indirect effects through the SRI for Cynicism.
Conclusions
In this study, individuals with evening type tend to experience a high degree of burnout (exhaustion, cynicism and professional efficacy) through the mediation effect of depression and stress response. Further study is necessary to reveal the effect of management of the depression and stress response in the employee with evening type.
