Clinical Utility of Impact of Event Scale-Revised for Diagnostic and Statistical Manual of Mental Disorders-Fifth Edition Posttraumatic Stress Disorder.

Objective: The Impact of Event Scale-Revised (IES-R) is a widely used self-report for assessing posttraumatic stress disorder (PTSD), originally aligned with Diagnostic and Statistical Manual of Mental Disorders (DSM)-IV diagnostic criteria. This study aimed to evaluate the applicability of the IES-R under the DSM-5 guidelines and establish a cutoff point for DSM-5 PTSD diagnosis.

Methods: A total of 238 participants recruited from multiple psychiatric centers, including 67 patients with PTSD, 72 patients with psychiatric controls, and 99 healthy controls, were included in the study.

Investigation of bismuth-based metal-organic frameworks for effective capture and immobilization of radioiodine gas.

In this study, we investigated the use of Bi-mna, a specific type of bismuth metal organic framework (MOF) for the capture and disposal of iodine, a key nuclide of concern in nuclear fuel reprocessing plants and nuclear power plants. To find the suitable form of Bi-mna for the purpose, experiments were performed by synthesizing four different Bi-mna with varying reagent ratios and connecting iodine adsorption and conversion for immobilization. After iodine adsorption and characterization to investigate their adsorption mechanisms, the Bi-mna samples went through conversion for immobilization to fix captured iodine into the adsorbents.

Objective: We aimed to identify the expectations and preferences for medication and medical decision-making in patients with major psychiatric disorders.

Methods: A survey was conducted among patients with major psychiatric disorders who visited psychiatric outpatient clinics at 15 hospitals between 2016 and 2018 in Korea.

Association between discrepancy in objective and subjective cognitive abilities and treatment response in patients with major depressive disorder: A CAN-BIND-1 study report.

Background: Major Depressive Disorder (MDD) is characterized by objective and subjective cognitive deficits. Discrepancies between objective and subjective cognitive performance can reflect under- to over-estimations of cognitive abilities, and these discrepancies are referred to as cognitive self-appraisals. Despite evidence that low self-appraisals are associated with depression, the modifiability of self-appraisals and their association with treatment outcome remains unclear.

Factors Associated With Health-Related Quality of Life Among Older People Exposed to the Jeju 4·3 Incident.

Objective: We explored factors associated with health-related quality of life (HRQOL), including socio-demographic and clinical characteristics, in among older people exposed to the Jeju 4·3 incident, and aimed to determine the effects of depression, posttraumatic stress disorder (PTSD) and perceived social support on HRQOL.

Methods: We obtained data from 110 survivors and 1,011 immediate family members of the victims of the Jeju April 3 incident (mean age, 75.1 years), and evaluated the relationships of HRQOL with sociodemographic and clinical characteristics including posttraumatic and depressive symptoms, and perceived social support.

Characteristics Associated with High Resilience among Aged People Exposed to the Jeju 4·3 Incident.

The purpose of this study was to identify characteristics related to high resilience among older people exposed to the Jeju 4·3 incident. A total of 1,121 aged adults were assigned to low, medium, and high resilience groups, and factors associated with low and high resilience were investigated. High resilience was significantly associated with a low prevalence of depression and high levels of life satisfaction and psychosocial support, as well as with younger age, being a man, higher education level, and current employment.

Association between Maternal Adverse Childhood Experiences and Risk of Post-traumatic Stress Disorder in the Offspring.

Objectives: Adverse childhood experiences (ACEs) of mothers may negatively affect the mental health of their offspring. Little is known about the intergenerational effect of maternal ACE on post-traumatic stress disorder (PTSD) in the offspring. This study inves-tigated the impact of maternal ACEs on PTSD in the offspring.

Background: The psychological consequences of the Jeju April 3 incident, which occurred almost 70 years ago, may be long-lasting. Thus, the present study investigated the prevalence and impact of comorbid post-traumatic stress disorder (PTSD) and depression among older people exposed to this incident.

Methods: A total of 110 survivors and 1,011 immediate family members of the victims of the Jeju April 3 incident completed a questionnaire that collected demographic information, the Center for Epidemiologic Studies Depression Scale (CES-D), and the PTSD Checklist-Civilian Version (PCL-C).

"Choosing Wisely": Apolipoprotein E Genetic Testing for the Diagnosis of Alzheimer's Disease in Dementia Clinics.

Background: Apolipoprotein E (APOE) ɛ4 allele carriers have an increased risk of late-onset Alzheimer's disease (AD). However, in the "Choosing Wisely" campaign for avoiding unnecessary medical tests, treatments, and procedures, APOE genetic testing is not recommended as a predictive test for AD.

Objective: The aim of this study was to investigate the potential value of APOE genetic testing in a specific clinical context.

Mediation Effects of Compassion Satisfaction and Compassion Fatigue in the Relationships Between Resilience and Anxiety or Depression Among Hospice Volunteers.

Hospice volunteers are a high-risk group for anxiety and depression owing to their frequent exposure to patients at the end of life and their subsequent deaths. Resilience is known to be a powerful factor that affects the occurrence of anxiety and depression; however, research on this subject is scarce. We investigated the relationship of resilience with anxiety or depression in hospice volunteers.

The Influence of Current Mood States on Screening Accuracy of the Mood Disorder Questionnaire.

Objective: In this study we investigated whether current mood states of patients with bipolar disorder have an influence on the screening accuracy of the Mood Disorder Questionnaire (MDQ).

Methods: A total of 452 patients with mood disorder (including 192 with major depressive disorder and 260 with bipolar disorder completed the Korean version of the MDQ. Patients with bipolar disorder were subdivided into three groups (bipolar depressed only, bipolar euthymic only, bipolar manic/hypomanic only) according to current mood states.

Clinical correlates associated with the long-term response of bipolar disorder patients to lithium, valproate or lamotrigine: A retrospective study.

Background: Although mood stabilizers such as lithium (LIT), valproate (VAL), and lamotrigine (LMT) appear to be efficacious treatments for bipolar disorder (BD) in research settings, the long-term response to these mood stabilizers in clinical practice is highly variable among individuals. Thus, the present study examined the characteristics associated with good or insufficient responses to long-term treatment with LIT, VAL, or LMT for BD.

Methods: This study retrospectively analyzed the medical records of patients who visited an outpatient clinic with a diagnosis of BD I or II.

Light Therapy for Patients With Bipolar Depression: Systematic Review and Meta-Analysis of Randomized Controlled Trials.

Objective: Bipolar disorder (BD) is challenging to treat, and fewer treatments are available for depressive episodes compared to mania. Light therapy is an evidence-based nonpharmacological treatment for seasonal and nonseasonal major depression, but fewer studies have examined its efficacy for patients with BD. Hence, we reviewed the evidence for adjunctive light therapy as a treatment for bipolar depression.

Association between subclinical hypothyroidism and metabolic syndrome among individuals with depression.

Background: Although the connection among low thyroid function, metabolic abnormalities, and depression is well documented, the relationship between subclinical hypothyroidism (SCH) and metabolic syndrome (MetS) in depression remains unclear. This study examined the association between SCH and MetS in a large sample with depression.

Methods: The study analyzed 370 individuals with depression who participated in the 2014 Korea National Health and Nutrition Examination Survey.
