Objective: Despite lower depression rates in men than in women, men’s suicide rates are significantly higher, suggesting potential gaps in depression screening. Rutz et al. developed the Gotland Male Depression Scale (GMDS), which includes symptoms commonly associated with male depression. This study was conducted to validate the Korean version of the GMDS (K-GMDS). Methods: The K-GMDS, Patient Health Questionnaire-9 (PHQ-9), and outpatient records of 233 new patients at the outpatient psychiatry department of Catholic University Hospital in Daegu from February and May 2022 were retrospectively reviewed. Internal consistency was measured using Cronbach’s α, and external validity was tested by analyzing the scale’s correlation with the PHQ-9. The screening capacity of the K-GMDS was tested based on the receiver operating characteristic (ROC) curve, sensitivity, specificity, and overall accuracy. Results: Of 233 patients, 42.6% (n=98) were classified to the depression group. Cronbach’s α was 0.92, and external validity was established with a Pearson’s correlation coefficient of 0.83 between the total score of the K-GMDS and the PHQ-9. While there were no significant differences in the area under the ROC curve between the K-GMDS and the PHQ-9, the K-GMDS had better sensitivity, specificity, and overall accuracy in screening depressive symptoms among men compared to the PHQ-9. Conclusion The K-GMDS exhibits satisfactory reliability and validity in psychiatric outpatient settings and outperforms the PHQ-9 in screening for depression among men. This study will be useful in developing male depression scales that are currently unavailable in South Korea.

Background: Posttransplant diabetes mellitus (PTDM) complicates kidney transplant recipients (KTRs) in morbidity and mortality. This study aimed to predict PTDM risk in KTRs using machine learning and deep learning models. Methods: Data were obtained from the Korea Organ Transplantation Registry, a nationwide cohort study of KTRs. Four machine learning algorithms, including eXtreme Gradient Boosting (XGBoost), CatBoost, light gradient boosting machine and logistic regression, and deep learning were implemented on 41 pretransplant and 31 posttransplant variables to predict PTDM. Model performance was assessed using the area under the curve (AUC) of the receiver operating characteristic curve, accuracy, precision, recall, and F1 score. Results: Among 3,213 KTRs, 497 patients (15.5%) developed PTDM within 1 year. The PTDM group had higher age, body mass index (BMI), triglyceride level, and prevalence of hypertension and cardiovascular disease, and lower total cholesterol level at baseline than the No-PTDM group. The XGBoost model showed the highest AUC (0.738) and F1 score (0.42), and modest accuracy (0.86), while the CatBoost model exhibited the highest accuracy (0.87) and precision (0.79). Feature importance in XGBoost was highest for recipient age, followed by baseline BMI, triglyceride level at posttransplant 6 months, baseline glycated hemoglobin and high-density lipoprotein cholesterol level, white blood cell (WBC) count and serum uric acid level at 6 months, baseline WBC count, and tacrolimus trough level at discharge. Conclusion The XGBoost model demonstrated the best performance for predicting PTDM within 1 year, offering an accurate tool for early identification and personalized care of high-risk KTRs for PTDM.

Depressive disorders are prevalent worldwide. Despite the availability of various antidepressants, treatment responses remain suboptimal, with disappointing remission rates. Recent advancements in antidepressant development have shifted focus to mechanisms beyond traditional monoamine neurotransmitters, such as serotonin and norepinephrine. Allopregnanolone, a neurosteroid, acts as a positive allosteric modulator of GABA A receptors, playing a significant role in regulating mood and anxiety. Fluctuations in allopregnanolone levels during reproductive cycles contribute to mood disorders such as premenstrual dysphoric disorder, postpartum depression (PPD), and menopausal depression. Recently, the Food and Drug Administration approved two novel antidepressants, brexanolone (IV) and zuranolone (oral). These synthetic analogs of allopregnanolone offer fast-acting relief for PPD by enhancing GABAergic inhibition. Additionally, these neurosteroid-based therapies provide new hope for patients with depression beyond PPD, due to their rapid onset of action. However, concerns regarding long-term safety and the potential for misuse remain, necessitating further research.This review explores the relationship between neurosteroids and depression, with a focus on the mechanisms and clinical applications of brexanolone and zuranolone in treating mood disorders.

Objectives: Recent advances in brain age prediction models reveal accelerated brain aging in major depressive disorder (MDD) patients. This review investigates the complex relationship between brain aging and biological age gap (BAG) in MDD, emphasizing the influences of clinical characteristics, treatment responses, and various neuroimaging techniques on this dynamic interplay. Methods: A systematic review of the existing literature was conducted, focusing on 18 studies that analyze brain aging patterns in MDD patients. Key factors such as age, clinical features, and lifestyle choices were examined to assess their impact on BAG and the overall neurobiological health of individuals with MDD. Results: The findings indicate that MDD patients frequently experience accelerated brain aging, particularly in elderly populations, with BAG serving as a valuable biomarker for assessing biological aging rates. The review highlights the urgent need for more granular approaches, considering variables such as age, gender, and socioeconomic status. Specific local brain aging patterns were observed in regions related to emotional regulation, suggesting that localized BAG changes may provide critical insights into the pathophysiology of MDD and its neurobiological underpinnings. Conclusions BAG is a significant biomarker for evaluating accelerated brain aging in MDD, informing personalized treatment strategies. Future research should incorporate diverse clinical characteristics and advanced neuroimaging techniques in representative samples to enhance the clinical applicability of BAG and deepen the understanding of its role in depression and biological aging.

BACKGROUND/OBJECTIVES: This study investigated the relationship between adolescent food-related lifestyles and food-related media use and eating behavior in Korea. SUBJECTS/METHODS: Participants were 392 Korean adolescents, ranging in age from 12 to 18, recruited via convenience sampling. They completed a self-report questionnaire survey consisting of questions about food-related lifestyle, food-related media use, food consumption behavior, food literacy, and nutrition quotient. Data analysis was conducted using SPSS 29.0. (IBM Co., Armonk, NY, USA). RESULTS: The factor analysis of food-related lifestyles identified four factors. Based on the cluster analysis results, participants were classified into three clusters reflecting different levels of interest: high interest in food, moderate interest in food, and low interest in food. The analysis revealed significant differences between groups in food-related liestyle factors (P < 0.05). Notably, the high-interest group demonstrated proactive engagement with food-related content, a willingness to explore diverse culinary experiences, and a conscientious consideration of nutritional labeling during food purchases. In contrast, the low-interest group reported tendencies toward overeating or succumbing to stimulating food consumption post-exposure to food-related content, coupled with a disregard for nutritional labeling when making food choices. A stronger inclination toward a food-related lifestyle was positively correlated with higher levels of food literacy and nutrition quotient. CONCLUSION This study proposes that the implementation of a nutrition education program using media could effectively promote a healthy diet among adolescents with a high level of interest in their dietary habits. For adolescents with low interest in their dietary habits, it suggests that introducing an education program with a primary focus on enhancing food literacy could be beneficial in fostering a healthy diet. Our research findings provide insight for the development of tailored nutritional education programs and establishment of effective nutrition policies.
