Treatment Effect of Psychoeducation and Training Program Using Virtual Reality Technique in the Patients with Depressive Symptoms / 신경정신의학

OBJECTIVES: To compare the clinical effectiveness of the virtual reality (VR) programs in assessing psychosocial problems, improving symptoms, and reducing suicide risk in depressive patients with those of pharmacotherapy.METHODS: Thirty-six patients were recruited with depression in the treatment group and 22 participants in the healthy control group through internet advertisements between November 2018 and March 2019. Participants in the treatment group were allocated randomly at a 1:1 ratio to either the VR group or pharmacotherapy group. At the baseline, all participants were assessed with a comprehensive battery for their psychological characteristics by structured scales using VR technologies. Assessments of patients in the treatment group were repeated four weeks after therapeutic intervention. The primary outcome measures were the Korean Version of Quick Inventory of Depressive Symptomatology-Self-Report and suicidality scales of the Korean Mini International Neuropsychiatric interview. The borderline personality (Personality Assessment Inventory-Borderline Features Scale) and resilience (Korean Resilience Questionnaire) were also evaluated.RESULTS: Twenty-four depressive patients completed the treatment, and the final assessment was conducted after four weeks of treatment. In the initial assessment, the patient group showed significantly higher depressive symptoms, suicidality, borderline personality trait, and lower resilience than healthy control group. After the four-week therapeutic interventions, the VR group showed significant improvement in depression, suicidality, borderline personality trait, and resilience. In addition, there was no significant difference in the treatment efficacy between the VR group and the pharmacotherapy group.CONCLUSION: In this study, the VR treatment program has clear benefits for emotional distress and reducing suicidality in depressive patients. Evidence-based VR treatments may show new clinical potential for depressive disorder.

Effects of Air Purifiers on Patients with Allergic Rhinitis: a Multicenter, Randomized, Double-Blind, and Placebo-Controlled Study

Purpose@#Exposure to particulate matter (PM) is a well-known risk factor in the triggering and exacerbation of allergic airway disease. Indoor environments, where people spend most of their time, are of utmost importance. To assess the effects of air purifiers [equipped with high-efficiency particulate air (HEPA) filters] on allergic rhinitis (AR) in adult patients, we performed a multicenter, randomized, double-blind, and placebo-controlled study. @*Materials and Methods@#Patients with house dust mite (HDM)-induced AR were randomly assigned to either active or mockup (placebo) air-purification groups. Two air purifiers (placed in living room and bedroom) were operated for 6 weeks in each home environment. The primary study endpoint was to achieve improvement in AR symptoms and medication scores. Secondary endpoints were to achieve improvement in the quality of life (QoL) and visual analog scale (VAS) scores, as well as in the indoor (bedroom and living room) concentrations of PM2.5 and PM10. @*Results@#After 6 weeks of air purifier use, medication scores improved significantly in the active (vs. placebo) group, although subjective measures (symptoms, VAS, and QoL scores) did not differ. Bedroom PM2.5 concentrations initially exceeded living room or outdoor levels, but declined (by up to 51.8%) following active purifier operation. Concentrations of PM2.5 in living room and PM10 in bedroom and living room were also significantly reduced through active purification. @*Conclusion@#The use of air purifiers with HEPA filters significantly reduced medication requirements for patients with HDM-induced AR and significantly lowered indoor PM2.5 concentrations, regardless of room placement. Active intervention to reduce household air pollutants may help improve allergic airway disease (clinicaltrials.gov NCT03313453).

Contents Analysis of Textbook Related to Safety Education in Elementary School

PURPOSE: The purpose of this study was to provide basic data to develop safety education programs in elementary school. METHOD: Analysis is made based on textbooks for 1st-6th-grade elementary school students published by Korea Ministry of Education & Human Resources Development. RESULTS: 1) Among the textbooks. only , , , and courses dealt with safety education. 2) The contents of safety education included traffic safety, water safety, indoor and outdoor safety, fire, emergency measures, misuse and abuse of drug, smoking, toy safety, sports safety, leasure safety and disasters. However, the contents were theoretical, fragmentary, local and limited. CONCLUSION: These results suggest that the consents of safety education must be strengthened, and more practical and more behavior-oriented in consideration of activities.
