Psychiatry Investigation

OBJECTIVE: This study aimed to examine the changes in serum nesfatin-1, leptin, orexin-A, and total ghrelin levels of patients diagnosed with drug-naive panic disorder (PD) before and after six weeks of the treatment and to compare the findings with the healthy subjects. METHODS: The neuropeptides were measured in venous blood samples taken from 32 patients and 32 healthy subjects. The blood samples of the patients who used paroxetine 20 mg/day plus alprazolam 0...

OBJECTIVE: Second-generation antipsychotics (SGAs) have revolutionized the treatment of psychiatric disorders, but are associated with significant metabolic risks, including diabetes and hyperglycemic crises. This review explores the complex interplay between antipsychotics, diabetes, and hyperglycemic crises, highlighting the mechanisms underlying SGA-induced diabetes. METHODS: We present the case of a patient with schizophrenia who was taking antipsychotic medication and was admitted to the emergency room due to the sudden onset of diabetic ketoacidosis (DKA) without any history of diabetes...

OBJECTIVE: Our study hypothesizes that the interaction between depression, alcohol intake, and smoking status can significantly influence the risk of acute coronary syndrome (ACS). We aim to investigate the magnitude of the association between depression and ACS risk and explore how alcohol intake and smoking status affect this association. METHODS: We used data from the Korean Genome and Epidemiology Study. The primary exposure of interest was the presence of depression, as measured using the Beck Depression Inventory score at baseline...

OBJECTIVE: We aim to explore the effects of transcranial direct current stimulation (tDCS) on food craving improvement and changes in brain function associated with craving by conducting a total of 10 sessions of tDCS over a period of 2 weeks on overweight and obese subjects. METHODS: A total of 15 patients who were overweight or obese (body mass index [BMI] ≥23 kg/m2) were included. Weight, BMI, neuropsychological variables, and food craving-related variables were assessed...

OBJECTIVE: Recently, burnout and mental health issues regarding nurses are reported increasingly. This study aimed to investigate the prevalence of anxiety symptoms among hospital nurses and determine their association with psychological and job-related factors. METHODS: Data on demographics, job-related characteristics, burnout, Type A behavior patterns, self-esteem, and happiness were collected from 515 nurses working at a university hospital in Korea. Anxiety symptoms were assessed using the anxiety subscale of the Hospital Anxiety and Depression Scale, with scores of 8 or higher indicating the presence of anxiety symptoms...

OBJECTIVE: To evaluate the association between atopic dermatitis (AD) and suicidal behaviors in adolescent defectors among residents who escaped from North Korean (adolescent defectors, n=423) and adolescents with South Korean parents (Korean adolescents, n=540,265). METHODS: The study used data from the Korea Youth Risk Behavior Survey conducted from 2011 to 2019. Differences in general characteristics, health behaviors, suicidal ideation, suicide plans, suicide attempts, and AD between adolescent defectors and Korean adolescents were examined...

OBJECTIVE: This study aims to determine the effects of online mindful somatic psychoeducation program (o-MSP) on mental health in female university students during the coronavirus disease-2019 (COVID-19). METHODS: Thirty-eight female university students were randomly assigned to an intervention group (IG, n=19) or a control group (CG, n=19). IG received o-MSP for 2-hours per session, twice weekly for 4-weeks; CG maintained their usual daily routine for 4-weeks. Measurements were performed pre- and post-intervention to assess stress, anxiety, and social connectedness using Perceived Stress Scale, State-Trait Anxiety Inventory, and Social Connectedness Scale...

OBJECTIVE: The relationship between screen use and problematic internet use (PIU; i.e., internet addiction) amongst adolescents has not been sufficiently explored. Further, there is even less research on how gender is associated with this relationship. The goal of the study was to examine adolescent screen use, PIU, and its impact on day-to-day routines of adolescents. METHODS: Participants were recruited from an outpatient pediatric clinic in São Paulo, Brazil...

OBJECTIVE: Non-Suicidal Self-Injury (NSSI) scars are common in individuals with NSSI experiences. However, little is known about NSSI scars because related tools are limited. This study aimed to develop and validate the Korean version of the multidimensional Non-Suicidal Self-Injury Scar Scale (K-NSSI-ScarS), consisting of three components: NSSI scar measurement, NSSI scar cognition, and NSSI scar concealment. METHODS: A total of 333 Korean adults with at least one NSSI scar and history of NSSI within the last 5 years (age: 18 to 39 years) completed the online survey...

OBJECTIVE: Sibling relationships in early childhood can have a positive impact on children's social interaction and communication skills. Similarly, autistic children can benefit from interactions with their siblings, who can serve as readily available partners for social interaction. However, there is a lack of research on the effects of siblings based on specific characteristics of the sibling. Therefore, the aim of this study is to compare social interactions and communication skills of autistic children based on sibling status and characteristics...

OBJECTIVE: We aimed to create an efficient and valid predicting model which can estimate individuals' brain age by quantifying their regional brain volumes. METHODS: A total of 2,560 structural brain magnetic resonance imaging (MRI) scans, along with demographic and clinical data, were obtained. Pretrained deep-learning models were employed to automatically segment the MRI data, which enabled fast calculation of regional brain volumes. Brain age gaps for each subject were estimated using volumetric values from predefined 12 regions of interest (ROIs): bilateral frontal, parietal, occipital, and temporal lobes, as well as bilateral hippocampus and lateral ventricles...

OBJECTIVE: The aim of this study was to explore the psychometric properties of the Insomnia Severity Index (ISI) based on modern test theory, such as item response theory (IRT) and Rasch analysis, with shortened versions of the ISI among the general population. METHODS: We conducted two studies to evaluate the reliability and validity of the shortened versions of the ISI in a Korean population. In Study I, conducted via online survey, we performed an exploratory factor analysis (n=400)...

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. The survey consisted of 12 questions about demographic variables and opinions on their expectations for medication, important medical decision-makers, and preferred drug type...

OBJECTIVE: Early trauma significantly affects the severity of panic disorder (PD) symptoms and suicidal ideation. However, few studies have explored the specific effects of different early trauma subtypes on PD. This study analyzed how childhood trauma subtypes, including general, physical, emotional, and sexual, influence panic and phobia levels and suicidal ideation in adults with PD and healthy controls (HCs). METHODS: In total, 455 adults with PD and 149 HCs participated in this study...

OBJECTIVE: A deep learning-based classification system (DLCS) which uses structural brain magnetic resonance imaging (MRI) to diagnose Alzheimer's disease (AD) was developed in a previous recent study. Here, we evaluate its performance by conducting a single-center, case-control clinical trial. METHODS: We retrospectively collected T1-weighted brain MRI scans of subjects who had an accompanying measure of amyloid-beta (Aβ) positivity based on a 18F-florbetaben positron emission tomography scan...

OBJECTIVE: Given the high suicide risk among people with schizophrenia and other mental disorders and the significance of intervention in the daily life setting, tailored gatekeeper training is necessary for families of people with mental disorders. This study evaluated the effectiveness of a suicide prevention education program for families of people with mental disorders (SPEM-F), developed by the Korea Foundation for Suicide Prevention. METHODS: Fifty-nine family members of people with mental disorders were recruited from eight community psychiatric rehabilitation centers in Korea and enrolled in a cluster randomized controlled trial...
