Purpose: Psychiatric conditions are common in children and adolescents with diabetes and can hinder disease management. In this study, we examined whether mental health status at diagnosis predicts glycemic control at 1 year. Methods: We included 57 patients aged 6–18 years diagnosed with type 1 or type 2 diabetes between 2019 and 2023 at Seoul National University Bundang Hospital. Mental health was assessed within 3 months of diagnosis using the Eating Disorder Inventory-2, Children’s Depression Inventory, and Child Behavior Checklist (CBCL) for ages 6–18. Poor glycemic control was defined as glycated hemoglobin >6.5% at 1 year. Associations between screening results and glycemic control were analyzed using Fisher exact test and multivariate logistic regression. Results: Of the 57 patients, 32 (56.1%) had type 1 diabetes, and the mean age at diagnosis was 12.9±3.1 years; 31 (54.4%) were male. Poor glycemic control at 1 year was observed in 16 patients (28.1%). Although individual subscale positivity was not significantly associated with glycemic control, borderline somatic complaints on the CBCL were significantly associated with poor control (p=0.022). In multivariate analysis, having 2 or more positive CBCL subscales showed a trend toward association with poor glycemic control (adjusted odds ratio=21.47, p=0.054). Conclusion Early psychological screening, especially for somatic symptoms or multiple psychological problems, may help identify those at risk for poor glycemic control in pediatric diabetes. These findings underscore the importance of early detection and intervention in optimizing diabetes management.

Purpose: Endoscopic submucosal dissection (ESD) has become a standard minimally invasive treatment for selected patients with early gastric cancer (EGC). This study presents the first nationwide survey of patients with EGC treated with ESD in 2023, conducted by the Korean College of Helicobacter and Upper Gastrointestinal Research. Materials and Methods: Data were retrospectively collected from participating referral centers across Korea using a standardized case report form covering patient characteristics, tumor features, procedural details, histopathological findings, and clinical outcomes.Descriptive and comparative analyses were conducted to summarize nationwide ESD practice patterns and outcomes. Results: Data from 5,460 ESD cases from 5,250 patients across 27 institutions were analyzed. The mean age was 67.4 years, with 74.1% males. Multiple synchronous lesions were identified in 3.7%. Most lesions were located in the lower third of the stomach (64.0%), and differentiated-type adenocarcinomas accounted for 87.8%. The en bloc and complete resection rates were 99.2% and 91.4%, respectively. Curative resection was achieved in 80.5%, whereas local non-curative resection (L-NCR) and surgical non-curative resection (S-NCR) were identified in 2.8% and 16.7%, respectively. Additional surgery was performed more frequently in patients with S-NCR than in those with L-NCR (59.3% vs. 24.7%). The bleeding and perforation rates were 3.6% and 0.9%, respectively, and were mostly managed conservatively or endoscopically. The median length of hospitalization was 4.0 days. Conclusions This first nationwide survey provides a comprehensive overview of the current practice of EGC treatment using ESD in Korea, demonstrating high technical success and safety, and establishing a baseline dataset for future longitudinal research.

Purpose: This study examined the levels of end-of-life care preparedness, importance, performance, and educational needs among community-based home care workers and identified factors influencing end-of-life care performance to inform hospice/end-of-life care education programs. Methods: This study used a descriptive, correlational design. The participants were 152 community-based home care workers with at least 6 months of work experience. Data were collected using structured questionnaires that assessed end-of-life care preparedness, importance, performance, and educational needs. Data were analyzed using descriptive statistics, correlation analysis, importance-performance analysis (IPA), and hierarchical multiple regression analysis using SPSS version 29.0. Results: Overall, end-oflife care performance was significantly lower than its perceived importance (t=14.41, P＜ 0.001), with the largest gaps observed in the caregiving support and emotional support domains. In the IPA, multiple items related to death preparation for patients/families, spiritual/ emotional support, and care around the time of death fell into the low-importance/lowperformance quadrant. Educational needs positively correlated with importance, intention,confidence, preparedness, and performance. In hierarchical regression, preparedness (β =0.21, P=0.03) and importance (β=0.26, P＜0.001) significantly predicted performance, explaining 15% of variance. Conclusion End-of-life care performance among home care workers was influenced by psychological factors, including preparedness, importance, and confidence in end-of-life care, as well as institutional and environmental factors. Standardized educational programs and organizational support are required to improve the quality of community-based end-of-life care.

Purpose: This study aimed to identify the factors influencing end-of-life care performance among community-based care workers prior to the implementation of the Integrated Care Support Act in South Korea. Methods: A cross-sectional survey was conducted among 153 community care workers who provided home-based services. Data were collected using structured questionnaires that assessed perceptions of a good death, attitudes toward end-of-life care, end-of-life care stress, and end-of-life care performance. Data analysis included descriptive statistics, independent t tests, Pearson correlation coefficients, and hierarchical multiple regression using SPSS version 29.0. Results: End-of-life care performance demonstrated a significant positive correlation with end-of-life care stress (r=0.43,P＜0.001). Hierarchical regression analysis identified end-of-life care stress (β=0.32, P＜ 0.001), gender (female; β=–0.20, P=0.01), and intention to participate in end-of-life care education (β=–0.20, P=0.01) as significant predictors. The final model explained 25%of the variance in end-of-life care performance. Conclusion End-of-life care stress was the strongest predictor of performance among community-based care workers, along with gender and intention to participate in end-of-life care education. These findings suggest that, when appropriately managed and supported, end-of-life care stress may function as a motivating factor rather than solely a burden. Therefore, structured education and emotional support interventions—such as debriefing and peer-based supervision—are recommended. Additionally, the implementation of the Integrated Care Support Act should be accompanied by institutional systems that facilitate effective end-of-life care practices.

Objective: Unilateral biportal endoscopic transforaminal lumbar interbody fusion (UBE-TLIF) has emerged as an alternative to open TLIF. However, limited evidence is available regarding the application of 3-dimensional (3D)-printed titanium cages in UBE-TLIF. We aimed to compare the clinical outcomes and fusion rates of UBE-TLIF and open TLIF using 3D-printed titanium cages. Methods: We retrospectively reviewed patients who underwent single-level TLIF with 3D-printed titanium cages between 2021 and 2023. The inclusion criterion was degenerative lumbar stenosis, while the exclusion criteria were trauma, infection, and multilevel surgery. Clinical and radiologic outcomes were compared between the UBE-TLIF and open TLIF groups. Results: Twenty-one patients underwent UBE-TLIF, and 21 underwent open TLIF. The visual analogue scale (VAS) for back (p=0.987) and leg pain (p=0.731) did not significantly differ between the groups at 1-year follow-up. However, VAS back pain at postoperative day 2 was significantly lower in the UBE-TLIF group than in the open TLIF group (p<0.001). Solid fusion was achieved in 21 patients (100%) in the open TLIF group and in 20 (95.2%) in the UBE-TLIF group (p=1.000). In multivariable logistic regression analysis, body mass index was the only factor that exhibited a significant relationship (odds ratio [OR], 0.70; 95% confidence interval [CI], 0.53–0.92; p=0.011) with interbody fusion. In contrast, the surgical method (UBE vs. open TLIF) was not a significant factor (OR, 0.47; 95% CI, 0.10–2.21; p=0.337). Conclusion Using a 3D-printed titanium cage for UBE-TLIF may yield comparable fusion rates to those of open TLIF.

Radical cholecystectomy is the standard procedure for gallbladder (GB) cancer, offering the possibility of cure. Many surgeons have increasingly expanded surgical indications following the growing trend of robotic surgery in hepatobiliary and pancreatic surgery. This study presents our experience with several robotic single-port (SP) plus one-port radical cholecystectomies using the da Vinci system (Intuitive Surgical). Data from five patients who underwent robotic SP radical cholecystectomy for GB cancer between April 2024 and December 2024 were retrospectively reviewed. All patients presented with imaging findings suggestive of localized GB cancer (T2 or lower). The median operative time was 145 minutes (range, 121–153 minutes), and the median number of harvested lymph nodes was five (range, five to eight). The median hospital stay after surgery was 6 days (range, 6–7 days), with no major complications reported. Robotic SP radical cholecystectomy is a safe and feasible option for GB cancer.

Gastroesophageal reflux disease (GERD) is a chronic and relapsing gastrointestinal disorder characterized by the reflux of gastric contents into the esophagus, leading to troublesome symptoms and/or complications. Since the publication of the 2020 Seoul Consensus on GERD, significant new evidence has emerged, particularly regarding acid-suppressive therapies and diagnostic approaches. This 2025 focused update aims to refine GERD management strategies by incorporating the latest evidence on acid suppressive therapies and regional considerations in Asian populations. This study builds on the 2020 Seoul Consensus by integrating systematic reviews, meta-analyses, and expert consensuses to offer updated recommendations for the definition and medical treatment of GERD. These guidelines incorporate recent advances in acid-suppressive therapies, particularly potassium-competitive acid blockers, and adopt updated diagnostic frameworks in accordance with the Lyon Consensus 2.0. Key clinical questions were identified and structured using the following format: Population, Intervention, Comparator, Outcome. The resulting recommendations address the initial treatment, long-term maintenance strategies, and role of personalized therapy based on disease severity, such as the grade of reflux esophagitis. Six key statements are presented: updated definition and classification of GERD (Statement 1); initial and long-term treatment strategies tailored to GERD phenotypes, such as non-erosive reflux disease, mild erosive esophagitis, and severe erosive esophagitis (Statements 2-5); and dose optimization strategies for long-term safety (Statement 6). These guidelines aim to support gastroenterologists and general healthcare providers in making individualized evidence-based decisions for GERD management.

Purpose: This study examined the awareness and knowledge levels regarding food additives among single-person adult households. Methods: An online survey was conducted with 715 single-person households aged between 19 and 64 years, residing in urban areas across 17 metropolitan cities and provinces nationwide. The questionnaire included items on the demographic characteristics, nutrition quotient, awareness of food additives and sources of information, trust in information sources, and knowledge related to food additives. Awareness and knowledge of food additives were analyzed according to the participants’ gender, age group, nutrition quotient grade, and reported awareness of food additives. Results: The proportion of respondents who reported an awareness of food additives was 53.0%, with significantly higher awareness among women and those classified in the medium or high nutrition quotient categories. Participants who were aware of food additives obtained information primarily from the internet, television, or radio. By contrast, those who were unaware attributed this to insufficient promotion and information, or to difficulty understanding the content related to food additives. The information provided by physicians, pharmacists, and professional literature was considered trustworthy, while trust in information disseminated by government agencies was notably low (< 20%). The perceived health risk score of food additives was 3.32, and significantly higher scores were observed among the subjects aged 50–64 years and those with medium or high nutrition quotient grades. The knowledge levels regarding food additives were significantly greater among older subjects, those with medium or high nutrition quotient grades, and those who reported awareness of food additives. Conclusion This study provides baseline data for developing food additive education tailored to single-person adult households, supporting educational media, program design, and promotional strategies, and extending its relevance from academic research to practical contributions in public health and consumer awareness.

The recent approval of trastuzumab deruxtecan for human epidermal growth factor receptor 2 (HER2)–low and HER2-ultralow breast cancer mandates an adequate assessment of these categories. Methods: Seven breast pathologists from the Breast Pathology Study Group of the Korean Society of Pathologists held an on-site expert consensus meeting. Fifteen sets of virtual whole slide images (WSI) of hematoxylin and eosin stain and HER2 immunohistochemistry were provided. The pathologists were given 60 minutes to submit their diagnosis of HER2 expression into null, ultralow, 1+, 2+, or 3+. Afterwards, in-depth discussion and consensus diagnoses were made by real-time visualization of the WSI. Results: After the consensus meeting, unanimous 100% agreements were seen only in five (33.3%) of the examined cases, which consisted of three 1+ cases and two 2+ cases. Two cases (13.3%) had mild disagreement, with only one pathologist’s disagreement. Of note, eight cases (53.3%) showed significant disagreement, defined by more than two pathologists’ disagreement. All HER2-null cases were reclassified as ultralow after consensus review, suggesting potential widespread underclassification of ultralow cases in clinical practice. Conclusions: Experts had significant discrepancies in interpreting HER2-low/ultralow status. It is important to assess if the distinction between HER2-low and ultralow is strictly required and if HER2-null breast cancer exists in reality.
