Racing thought, when patients incessantly shift from one word or sentence to another while pending previous ones unfinished, is a symptom of (hypo)mania in bipolar disorders received less attention hitherto. Here, based on few evidence, we aim to unfold our hypothetical viewpoint that the frontopolar cortex that is believed to play a part in multitasking and management of competing goals might be dysfunctional in bipolar patients and may contribute in induction of flight of ideas. We then address new avenues for future research and try to encourage researchers to design more comprehensive studies to either accept or decline this proposed conjecture.
psychological and neurophysiological predictors of social functioning. Methods Twenty-seven patients with schizophrenia and thirty patients with bipolar disorder, as well as twenty-five healthy controls, completed measures of social functioning (questionnaire of social functioning), neurocognition (Verbal fluency, Korean-Auditory Verbal Learning Test), and social cognition (basic empathy scale and Social Attribution Task-Multiple Choice), and the childhood trauma questionnaire (CTQ). For neurophysiological measurements, mismatch negativity and heart rate variability (HRV) were recorded from all participants. Multiple hierarchical regression was performed to explore the impact of factors on social functioning. Results The results showed that CTQ-emotional neglect significantly predicted social functioning in schizophrenia group, while HRVhigh frequency significantly predicted social functioning in bipolar disorder patients. Furthermore, emotional neglect and HRV-HF still predicted social functioning in all of the subjects after controlling for the diagnostic criteria. Conclusion Our results implicated that even though each group has different predictors of social functioning, early traumatic events and HRV could be important indicators of functional outcome irrespective of what group they are.
Objective Many depressed adolescents do not seek professional help despite there being evidence-based treatments for depression, such as cognitive behavioral therapy or computer-based therapy. To increase professional help-seeking behavior in depressed adolescents, it is necessary to positively change help-seeking attitudes. This study aimed to explore the effect of sub-groups of help-seeking attitudes, gender, and depression level on adolescents’ help-seeking intentions and their perceptions of computer-based psychotherapy. Methods Participants were 246 adolescents aged 13–18 years recruited from six middle and high schools in South Korea. Measures were self-administered questionnaires, and included the Patient Health Questionnaire-9, the Attitudes Toward Seeking Professional Psychological Help Scale, the Intention to Seek Counseling Inventory, Preferences for Depression Treatment, and the Perceptions of Computerized Therapy Questionnaire. Results Help-seeking intentions were positively related with female gender and the recognition of the need for help. A higher level of confidence in therapists was related to high preference for computer-based therapy and face-to-face therapy. Adolescents with more severe depression were more likely to prefer pharmacotherapy. The perceptions of computer-based therapy were more positive in male adolescents, and in adolescents with a higher level of confidence in therapists yet a lower level of interpersonal openness. Conclusion To promote adolescents’ help-seeking behavior, improvement of the recognition of the need for help is required, especially among male adolescents. Computer-based therapy provides an alternative for male adolescents with high confidence in therapists yet low interpersonal openness. Consideration of the help-seeking attitudes and gender is needed when providing therapeutic intervention to depressed adolescents
Objective Previous studies have shown that there is a correlation between lipid levels and depressive mood, and that lipids could be useful biomarkers for depression. We conducted this study to clarify the association between lipid levels and depressive mood in adolescents, especially in community samples. Methods We analyzed data from the Korea National Health and Nutrition Examination Survey (KNHANES) that was conducted from 2013 to 2016. A total of 2,454 adolescents aged 12–18 years (1,273 boys, 1,181 girls) participated in the Survey. We conducted a cross-sectional study using multiple logistic regression, adjusting for age, household income, daily energy intake, daily fat intake, and daily cholesterol intake, to assess the association between depressive mood and serum lipid levels. Results Depressive mood was found in 8.7% of those included in the study. Borderline (110–129 mg/dL) and high (≥130 mg/dL) levels of low-density lipoprotein cholesterol (LDL-C) were significantly associated with depressive mood [Borderline level: odds ratio (OR)=5.55, 95% confidence interval (CI) 1.56–19.81, p=0.01; High level: OR=5.73, 95% CI 1.06–31.08, p=0.04]. However, this association was not found in girls. Conclusion Our findings indicate that depressive mood in boys is associated with higher LDL-C levels. Further investigation regarding this relationship and the underlying biological mechanisms is needed.

Objective This study aimed to assess the anxiety and depression in patients undergoing hematopoietic stem cell transplantation (HSCT). Methods Eighty-seven adult patients with various hematologic diseases, who were scheduled to receive autologous or allogeneic HSCT, were enrolled. The M.D. Anderson Symptom Inventory and the Hospital Anxiety Depression Scale were applied prospectively at hospital admission (D-14), on the day of transplantation (D day), and at 7 (D7) and 14 days (D14) after transplantation. Results The severity of both anxiety and depressive symptoms increased over time, with a peak at D7, and then showed a downturn at D14. Physical distresses also started with mild intensity at base line, which were continuously aggravated until D7, and then a partial recovery afterwards. Approximately, 52% of the participants had significantly high anxiety or depression before the start of HSCT. The occurrence of aggravation of pain, nausea, shortness of breath, and lack of appetite was associated with the development of anxiety during isolation period. The patients with significant baseline anxiety had higher scores on fatigue and shortness of breath items at D7 compared to those without. Conclusion Our finding suggests the importance of psychiatric approaches, including preventive measures, for the patients undergoing HSCT.
Objective Cyanidin-3-glucoside (C3G), is a component of anthocyanin, have been considered to positively influence cognition and be beneficial for the prevention and treatment of dementia. We aimed to assess the safety and efficacy of cyanidin-3-glucoside-rich Oryza sativa L. (black rice) extract on cognitive function. Methods A 12-weeks double-blind randomized, placebo controlled trial assessed safety and cognitive outcomes in participants with subjective memory impairment (n=48) following consumption of 6 black rice extract capsules or a placebo. Cognitive function was assessed using the ADAS-cog and the CERAD-K. Subjective memory impairment also assessed. Safety was assessed by hematologic blood test, urine analysis, and participant reports of adverse events. Results There was significant improvement on subjective memory in intervention group. There was no statistically significant difference in objective cognitive outcomes following 12 weeks of consuming black rice extract. ADAS-cog scores, however, trended toward improvement in the intervention group compared to the placebo group. There was no adverse event. Conclusion Although significant improvement in objective cognitive function was not proved, we found that C3G-rich Oryza sativa L. extract improves subjective memory in this study. Therefore the results may be informative of the possible effectiveness of the C3G-rich Oryza sativa L. on cognitive function.

Objective Empathy is important in the education of medical students. Many psychosocial variables are related to empathy. The aim of the study was to investigate the relationship between empathy and psychosocial factors such as burnout, personality, self-esteem, and resilience. Methods The participants completed a set of self-reporting questionnaires, including questions related to socio-demographic characteristics, the Korean edition of the Jefferson Scale of Empathy, student version (JSE-S-K), Maslach Burnout Inventory General Survey (MBIGS), NEO Five-Factor Inventory (NEO-FFI), Rosenberg Self-esteem Scale (R-SES), and Connor-Davidson Resilience Scale (CD-RISC). Partial correlation and regression analyses were performed. Results In male students, there were positive correlations between JSE-S-K and R-SES (r=0.229, p=0.002); conscientiousness of the NEO-FFI (r=0.153, p=0.037) and negative correlations, specifically between JSE-S-K and depersonalization of MBI (r=-0.206, p=0.005). In female students, there was positive correlations between JSE-S-K and personal accomplishment of MBI (r=0.384, p=0.004). In the multiple regression model, the JSE-S-K was affected by conscientiousness of the NEO-FFI (adjusted R2=0.245, β=0.201, p=0.001); depersonalization, personal accomplishment of the MBI-GS (β=-0.188, p=0.001, β=0.143, p=0.017); R-SES (β=0.176, p=0.004); sex (β=0.117, p=0.029). Conclusion The present findings suggested that conscientiousness, depersonalization, personal accomplishment, self-esteem and sex have an influence on empathy. Therefore, these must be considered in medical education and can be helpful to nurture more empathetic doctors.

Objective Resilience and impulsivity have opposite effects on depression in stressful situations. This study aimed to investigate the association among resilience, impulsivity, and depression in young males. Methods The participants consisted of 429 conscripts who underwent military training over 5 weeks. The surveys included the Connors- Davidson Resilience Scale-Korean version, the Barratt Impulsiveness Scale-11-Revised, and the Center for Epidemiological Studies- Depression Scale. The surveys were administered both before and after training. Results When simultaneously considering impulsivity and resilience, resilience was not associated with depression. Impulsivity had a complete negative mediating effect on resilience and depressive symptoms. Impulsivity is a significant negative mediating factor for the protective effect of resilience on depression. Conclusion This study recommends considering impulsivity when evaluating the protective role of resilience against depression.

Objective The suicide rate in South Korea was the second highest among the Organization for Economic Cooperation and Development countries in 2017. The purpose of this study is to understand the characteristics of people who died by suicide in Korea from 2013– 2017 and to better prevent suicide. Methods This study was performed by the Korea Psychological Autopsy Center (KPAC), an affiliate of the Korea Ministry of Health and Welfare. According to the Korea National Statistical Office, the number of suicide victims nationwide was estimated to reach about 70,000 from 2013 to 2017. Comprehensive suicide records from all 254 police stations in South Korea were evaluated by 32 investigators who completed a 14-day didactic training program. Then, we evaluated the characteristics of suicide victims in association with disease data from the National Health Insurance Database (NHID), which is anonymously linked to personal information of suicide victims. Results Thirty-one of 254 police stations in the Seoul metropolitan area were analyzed by August 10, 2018. Findings showed that the characteristics of suicide victims differed according to the nature of the region. Conclusion Our results suggest that different strategies and methods are needed to prevent suicide by regional groups.
