Background: Circadian rhythms have gained importance in the field of psychiatry because of their involvement in overall body functions and their association with mental health. This study investigated the relationship between circadian rhythms, depressive symptoms, anxiety symptoms, and chronotype. Methods: Circadian rhythms, depression and anxiety symptoms, hypomanic symptoms, quality of life, hopelessness, and chronotype were evaluated in 30 healthy adults. Results: Multiple linear regression analysis revealed statistically significant correlations between Biological Rhythms Interview of Assessment in Neuropsychiatry (BRIAN) scores and certain factors. Particularly, Quick Inventory of Depressive Symptomatology (p=0.009), Beck Anxiety Inventory (p=0.03), and Morningness-Eveningness Questionnaire (p<0.001) were found to be significant predictors of the degree of circadian rhythm disruption, as measured by BRIAN. The results showed that irregularity in circadian rhythms was associated with depression and anxiety symptoms, and no significant correlation was observed between chronotype and irregularity in the circadian rhythms. The findings indicated that misalignment between an individual’s chronotype and societal norms, such as work schedules and meal times, could contribute to circadian rhythm disruption, particularly in individuals with an evening chronotype. In contrast, this disruption was associated with an increased risk of anxiety and depression. Conclusion These findings provide important information to better understand the impact of circadian rhythms on mental health.

BACKGROUND: Physical activity is an important factor for preventing osteoporosis. This study aimed to investigate the association of work- and leisure-time physical activities with osteoporosis in postmenopausal women.METHODS: Data were obtained from the Korea National Health and Nutritional Examination Survey 2015–2016. A total of 2,885 postmenopausal women were included in the analysis. The subjects were divided into 3 groups according to the intensity of the work- and leisure-time physical activities. T-test, chi-square test, and multivariable logistic regression analysis were used.RESULTS: No association was found between work-time physical activity and osteoporosis prevalence. However, a dose-response relationship was found in case of leisure-time physical activity. People with leisure-time physical activity of at least >1,000 MET-min/week showed lower prevalence of osteoporosis.CONCLUSION: An appropriate level of leisure-time physical activity should be recommended to prevent and treat osteoporosis.

Objective: More recently, attention has turned to the linkage between childhood trauma and emotional dysregulation, but the evidence in bipolar disorder (BD) is limited. To determine neurobiological relationships between childhood trauma, current anxiety, and impulsivity, we investigated cortical volumetric correlates of these clinical factors in BD. Methods: We studied 36 patients with DSM-5 BD and 29 healthy controls. Childhood trauma, coexisting anxiety, and impulsivity were evaluated with the Korean version-Childhood Trauma Questionnaire (CTQ), the Korean version-Beck Anxiety Inventory (BAI), and the Korean version-Barratt Impulsiveness Scale (BIS). Voxel-based morphometry (VBM) was used to assess gray matter volume (GMV) alterations on the brain magnetic resonance imaging (MRI). Partial correlation analyses were conducted to examine associations between the GMV and each scale in the BD group. Results: Childhood trauma, anxiety, and impulsivity were interrelated in BD. BD patients revealed significant inverse correlations between the GMV in the right precentral gyrus and CTQ scores (r=-0.609, p<0.0003); between the GMV in the left middle frontal gyrus and BAI scores (r=-0.363, p=0.044). Moreover, patients showed similar tendency of negative correlations between the GMV in the right precentral gyrus and BIS scores; between the GMV in the left middle frontal gyrus and CTQ scores. Conclusion The present study provides evidence for a neural basis between childhood trauma and affect regulations in BD. The GMV alterations in multiple frontal lobe areas may represent neurobiological markers for anticipating the course of BD.

Objective: To report our experience with management of fetuses with congenital high airway obstruction syndrome (CHAOS). Methods: We retrospectively reviewed the cases of fetuses who were prenatally diagnosed and postnatally confirmed with CHAOS between 2010 and 2019 at Asan Medical Center, Seoul, Korea. Results: Of 13 fetuses prenatally diagnosed with CHAOS, 7 were lost to follow-up and 6 were postnatally confirmed as having CHAOS. All fetuses, except one were delivered via cesarean section with an ex utero intrapartum treatment (EXIT) procedure. Two patients had coexisting congenital heart diseases requiring several cardiac surgeries following birth. Both of these patients demonstrated developmental delay; however, the remaining 4 had a normal development except for expressive language. Two infants died of respiratory complications, and the remaining 4 were alive at the end of the follow-up period. All 4 live patients underwent tracheostomy with planned reconstruction surgery. Three children are now able to phonate, and 1 can maintain a conservation. Conclusion The proper management of CHAOS using the EXIT procedure results in high survival and low hypoxemia-induced complication rates. Therefore, an accurate prenatal diagnosis is necessary for an appropriate perinatal management.
