Background: The discovery and evaluation of reliable biomarkers of vitiligo are important;however, no clinically established serological markers exist for predicting the clinical prognosis of vitiligo. Objective: To investigate the levels of SOX10 and lamin A/C antibodies in the serum of patients diagnosed with vitiligo. Methods: In this multicenter prospective study, blood serum samples were collected from adult vitiligo patients. The levels of SOX10 and lamin A/C antibodies were analyzed by direct sandwich enzyme-linked immunosorbent assay. Antibody levels between the groups were compared according to disease activity and subtype. Results: A total of 80 patients (46 females; median age 60 years) were enrolled, including 56 (70%) with nonsegmental vitiligo and 27 (33.7%) with active disease. Positivity for SOX10 and lamin A/C antibodies was observed in 35.0% and 71.3% of patients, respectively. SOX10 positivity was significantly higher in active vitiligo than in stable vitiligo (59.3% vs. 24.5%; p=0.003), whereas lamin A/C positivity did not show significant difference (77.8% vs. 69.8%; p=0.60).No significant associations were found between SOX10 or lamin A/C status and the subtype, extent, or the presence of antinuclear antibody, anti-thyroid peroxidase, or anti-thyroglobulin (all p>0.05). Conclusion SOX10 antibody could be a potential marker for assessing disease activity in vitiligo. The increased production of SOX10 antibodies in the serum may be due to the underlying death or turnover of SOX10 containing cells under active autoimmune response.

Purpose: Pediatric surgery in Korea has historically been undervalued under the national fee system. Since 2021, the government has progressively expanded surgical add-on reimbursement for pediatric surgeries, yet their real-world impact remains unclear. Methods: We retrospectively analyzed pediatric surgeries (<19 years) performed at 4 tertiary institutions from 2020 to 2025. Surgeries were divided into 4 periods based on major policy changes. Variables included the number of surgeries, claimed surgical fees, patient age and weight, and eligibility for add-on reimbursement. Trends over time and variations among hospitals were examined. Results: A total of 1,959 surgeries were analyzed. Surgical volume did not significantly change across periods (P = 0.342).In contrast, total claimed surgical fees increased 1.66-fold in Period 2, 3.26-fold in Period 3, and 3.42-fold in Period 4 compared with Period 1. The proportion of surgeries eligible for add-on reimbursement rose to 76.6% in Period 4. The average claimed fee per case increased from 973,446 Korean won in Period 1 to 3,463,428 in Period 4. Patients <1,500g demonstrated the largest increase (471%). Across hospitals, the magnitude of claimed fee increases varied, but all institutions showed substantial growth in claimed surgical fees. Conclusion Stepwise expansion of pediatric surgical add-on reimbursement substantially increased claimed surgical fees across institutions without inflating surgical volume. These reforms improved financial reimbursement and may support future improvements in workforce sustainability, training, and care equity. Continuous policy monitoring will be essential to ensure long-term effectiveness and fiscal balance.

Objective: This study aimed to develop a reliable and valid Mixed State Severity Index (MSSI) to assess mood instability in patients with mood disorders and determine cutoff scores. Methods: Twenty-one items were selected based on Koukopoulos’ criteria for mixed depressive episode, historically referred to as agitated depression, and Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, Text Revision mixed features criteria. The MSSI was administered to 242 patients (major depressive disorder [n=92], bipolar disorder [BD] I [n=78], and BD II [n=72]) and 726 controls. Results: The MSSI demonstrated high internal consistency (α=0.78–0.90). Exploratory factor analysis revealed a stable four-factor structure. Based on receiver operating characteristic analysis, optimal cutoff scores were identified to distinguish mood disorder groups from controls, ranging from 19.5 to 27.5 depending on diagnosis. Conclusion The MSSI is a reliable and valid instrument for assessing the severity of mixed features in patients with mood disorders. The established cutoff scores enhance its clinical utility, providing robust diagnosis and treatment planning support.

Background: s/Aims: While large-for-size syndrome is uncommon in liver transplantation (LT), it can result in fatal outcome. To prevent such fatality, we manufactured 3D-printed intra-abdominal cavity replicas to provide intuitive understanding of the sizes of the graft and the patient’s abdomen in patients with small body size between July 2020 and February 2022. Methods: Clinical outcomes were compared between patients using our 3D model during LT, and patients who underwent LT without 3D model by using 1 : 5 ratio propensity score-matched analysis. Results: After matching, a total of 20 patients using 3D-printed abdominal cavity model and 100 patients of the control group were included in this study. There were no significant differences in 30-day postoperative complication (50.0% vs. 64.0%, p = 0.356) and the incidence of large-for-size syndrome (0% vs. 7%, p = 0.599). Overall survival of the 3D-printed group was similar to that of the control group (p = 0.665), but graft survival was significantly superior in the 3D-printed group, compared to the control group (p = 0.034). Conclusions Since it showed better graft survival, as well as low cost and short production time, our 3D-printing protocol can be a feasible option for patients with small abdominal cavity to prevent large-for-size syndrome after LT.

Purpose: Dorsal comminution is widely accepted as a prognostic factor for reduction loss in the nonoperative treatment of distal radius fractures. However, the reliability of measuring dorsal comminution in simple radiographs has not been adequately studied. This study investigated the reliability of dorsal comminution measurements from simple radiographs, based on inter- and intra-rater reliability indices. Methods: We included 40 patients with distal radius fractures who underwent operative treatment from March 2016 to March 2017. We established three definitions for dorsal comminution: first, the rater’s subjective judgment; second, the presence of a free-floating piece of dorsal cortex; and third, the presence of a dorsal cortical defect of 5 mm or greater. Reliability was measured using Fleiss’ or Cohen’s kappa. Results: Based on Cohen’s kappa values, the intra-rater reliability of dorsal comminution assessment demonstrated fair to good agreement. In contrast, inter-rater reliability was generally poor to fair, and subgroup analysis by rater experience revealed poor agreement among less experienced surgeons. Conclusion The radiological predictors of dorsal comminution exhibited overall low reliability, limiting their usefulness in predicting reduction loss in distal radius fractures. A more precise definition of dorsal comminution is necessary, and additional methods, such as computed tomography and artificial intelligence, should be considered to increase reliability.

Objective: Objective of this study is to evaluate the association between high risk of depression and metabolic diseases such as hypertension, diabetes, and dyslipidemia in Korean cervical cancer patients. Methods: A total of 330 women with cervical cancer were included in this study, using data from the Korea National Health and Nutrition Examination Survey from 2010 to 2021. Participants were categorized into two groups—high risk of depression and non-depression—based on their answers to survey items related to depression. A multivariate logistic regression analysis was used to evaluate the influence of metabolic diseases on high risk of depression in patients with cervical cancer. Results: A total of 78 (23.64%) and 252 (76.36%) women were classified into the high risk of depression and non-depression groups, respectively. In multivariate logistic regression analysis adjusting for age, menopausal status, and smoking status, diabetes was associated with an odds ratio of 2.47 (95% confidence interval: 1.205, 5.071) for high risk of depression in cervical cancer patients. However, among the metabolic diseases, hypertension, and dyslipidemia were not associated with high risk of depression in patients with cervical cancer. Conclusion This study suggests that diabetes may be associated with a increased risk of high risk of depression in cervical cancer patients. Therefore, appropriate treatment of diabetes in cervical cancer patients may contribute to lowering the risk of depression in the future.
