OBJECTIVES: This study was aimed to investigate the associations of childhood trauma with psychopathology and clinical characteristics in patients with schizophrenia. METHODS: This study enrolled 66 inpatients with schizophrenia. Korean Childhood Trauma Questionnaire (K-CTQ) and Life Event Questionnaire (LEQ) were administered to assess childhood trauma. Psychopatholgy and clinical characteristics were assessed with the Positive and Negative Syndrome Scale (PANSS), Beck Depression Inventory (BDI), Korean Version of Internalized Stigma of Mental Illness (K-ISMI), Perceived Stress Scale (PSS), and visual analogue scale of EuroQoL-5 Dimension Index (EQ-5D). RESULTS: Total scores on K-CTQ were positively associated with scores on the BDI, K-ISMI, PSS, and PANSS and negatively associated with the score on the EQ-5D. Among subscales of K-CTQ, emotional abuse was significantly associated with all measures for psychopathology and clinical characteristics. Patients with physical abuse (36.5%), emotional abuse (30.2%), or bullying (30.6%) according to the LEQ showed sighificanlty higher the ISMI score and lower EQ-5D score. Emotional abuse and bullying were also significantly associated with higher scores on BDI and/or PSS. CONCLUSION: Our results suggest that childhood trauma negatively influences on internalized stigma, depression, perceived stress and quality of life in patients with schizophrenia. Clinicians should carefully evalute and manage childhood traumatic experience of patients with schizophrenia.

Mineral trioxide aggregate (MTA), which was originally developed for repair of root perforations, is a biocompatible material with numerous clinical applications in endodontics. MTA must be allowed to set in the presence of moisture to optimize the material's physical and chemical properties. In the clinic, occasionally unset MTA has been detected after application of MTA on the tooth, and the reason has been unclear. This case report presents MTA washed-out for several years after placement at the root apex as an apical plug, and discusses the reason and things to consider in clinics.

Background: In this study, the relationship between depression and stress-coping strategies among public enterprise workers whose workplaces were relocated to a newly-built innovation city was investigated. Methods: This study included a total of 922 public enterprise workers living in Naju Innovation City. Along with their sociodemographic data, each subject was assessed concerning depression, occupational stress, and stress-coping strategies using the Center for Epidemiologic Studies Depression Scale(CES-D), Korean Occupational Stress Scale (KOSS), and stress-coping scale (SCS), respectively. Logistic regression was performed to investigate the impact of the relevant factors on depressive symptoms. Results: The overall prevalence of depressive symptoms was 14%. Some sociodemographic variables, the total scores of the KOSS, and four subscales of the SCS revealed significant differences between the depressed and normal groups. Multivariate regression analysis revealed that the KOSS (odds ratio [OR], 1.17; p<0.001) and SCS, such as problem-solving-focused (OR, 0.75; p<0.001), emotion-focused (OR, 1.15; p<0.05), and wishful-thinking-focused (OR, 1.10; p<0.05), were significantly associated with depression. Conclusion The results indicated that depressive symptoms were highly prevalent among workers whose workplaces were relocated. In addition, these symptoms were found to be related with occupational stress and stress-coping strategies. Our findings also suggest that promoting healthy stress-coping strategies and reducing occupational stress may help in preventing the occurrence of depression and managing depressed workers.

Background: This study aimed to examine the influence of the coronavirus disease pandemic 2019 (COVID-19) by comparing the incidences of depression, suicidal ideation, and suicidal attempts before and after the outbreak of the pandemic among community-dwelling older adults. Methods: In total, 9,784 older adults were recruited from 22 counties in Jeollanam-do between 2019 and 2022. Selfreported questionnaires, including sociodemographic factors, suicidal ideation, suicidal attempt, and Geriatric Depression Scale-Short Form Korean version, were used. Results: The proportion of the depression high-risk group tended to increase since the COVID-19 outbreak, increasing to 16.3%, 23.1%, and 25.7% in 2019, 2020, and 2021, respectively; however, decreased to 21.8% in 2022. The incidence of suicidal ideation showed a similar pattern. The incidence of suicidal attempts showed a different pattern, rising to 1.3% and 2.6% in 2019 and 2020, respectively and then falling to 1.1% and 0.8% in 2021 and 2022, respectively. Conclusion This study examined community-dwelling older adults and their mental states during the COVID-19 pandemic, and found that the risk of depression among older adults increased 1.708-fold in 2020, 1.877-fold in 2021, and 1.599-fold in 2022 compared to that in 2019, the year before the pandemic. Similarly, the risk of suicidal ideation increased by 1.582-fold in 2020, 1.913-fold in 2021, and 1.623-fold in 2022 compared with 2019 data. As the pandemic extended, mental health states improved; however, not to prepandemic levels. Suggesting that older people need continued support to alleviate the negative effects of the COVID-19 pandemic.

The Pfizer-BioNTech COVID-19 vaccine has shown excellent clinical effectiveness; however, adverse events of the vaccine remain a concern in Korea. We surveyed adverse events in 2498 healthcare workers vaccinated with the Pfizer-BioNTech COVID-19 vaccine at a university hospital. The survey was conducted using a diary card for 7 days following each injection. The questionnaire response rate was 75.1% (1876/2498) for the first dose and 73.8% (1840/2493) for the second dose. Among local reactions, pain was the most commonly reported (84.9% after the first dose and 90.4% after the second dose). After the second dose, two people visited the emergency room due to severe local pain, but no hospitalization or skin necrosis occurred. Among systemic reactions, fatigue was most frequently reported (52.8% after the first dose and 77.0% after the second dose), followed by myalgia (49.0% and 76.1%), headache (28.7% and 59.2%), chills (16.7% and 54.0%), and arthralgia (11.4% and 39.2%). One or more critical adverse events occurred in 0.2% and 0.7% of the vaccinees. Except for urticaria, more adverse events were reported after the second dose than after the first dose. In the future, adverse events should be investigated in older adults, and a future study with a longer observation period should be conducted.
