The sixth edition of the Korean Medication Algorithm Project for Depressive Disorder (KMAP-DD) was published in 2025. This review compared KMAP-DD 2025 with four major international clinical practice guidelines: Canadian Network for Mood and Anxiety Treatments Clinical Guidelines for the Management of Major Depressive Disorders, National Institute for Health and Care Excellence Depression Guideline, Royal Australian and New Zealand College of Psychiatrists Clinical Practice Guidelines for Mood Disorders, and British Association for Psychopharmacology Guideline. While KMAP-DD is based on expert consensus, and others on evidence-based methods, overall treatment strategies for depressive episodes were fairly consistent. Especially, KMAP-DD 2025 offers more structured recommendations in areas lacking strong evidence, such as premenstrual dysphoric disorder, perinatal depression, and depression with medical comorbidities. KMAP-DD 2025 also reflected Korean clinical practice patterns emphasizing rapid symptom relief and early use of combination strategies. Despite limitations as a consensus-based guideline, KMAP-DD 2025 complements evidence-based approaches and provides practical, situation-specific guidance for real-world clinical decision-making in Korea.

Purpose: This study aimed to develop and implement an antimicrobial stewardship education program for physician assistant nurses and to evaluate its effects on their knowledge and clinical performance. Methods: A quasi-experimental, single-group pre-post design was conducted with 50 physician assistant nurses at a university hospital in Seoul, Republic of Korea. The antimicrobial stewardship education program, developed using the ADDIE model, consisted of 12 sessions including lectures and case-based learning (CBL)-based discussions.Knowledge was measured before and immediately after the intervention, while performance was assessed pre-intervention and four weeks post-program. Data were analyzed using paired t-tests, Wilcoxon signed-rank tests, and analysis of covariance (ANCOVA). Results: Knowledge scores significantly improved from 44.65±7.45 to 58.50±10.11 (p<.001), and all subdomains showed significant increases (p<.001). Performance scores increased from 3.68±0.77 to 4.28±0.68 (p<.001). Knowledge gain did not differ significantly between the medical and surgical departments (p=.710). Likewise, after adjusting for pre-test scores, no significant difference in performance improvement was observed between the two departments (ANCOVA, p=.170). These results indicate that the program was effective across both departments regardless of their characteristics. Conclusion The antimicrobial stewardship education program improved both knowledge and performance among physician assistant nurses. This program may contribute to the standardization of antimicrobial stewardship education and to appropriate antimicrobial use and the reduction of antimicrobial resistance.

Background: Basal cell carcinomas (BCCs) are often misdiagnosed as benign lesions, leading to inappropriate laser ablation. Misidentification may cause delays in proper diagnosis and surgical intervention, potentially affecting patient outcomes. Objective: We investigated the percentage of patients with BCC who were inappropriately treated with laser ablation following the introduction of dermoscopic examination reimbursement and analyzed their clinical and histological characteristics. Methods: We retrospectively reviewed the data of 106 patients with histologically confirmed BCC after reimbursement for dermoscopic examinations was implemented. Results: Among the 106 patients pathologically diagnosed with BCC, 11 patients (10.4%) had a history of laser ablation after being misdiagnosed with a benign lesion. All patients had pigmented BCCs on their faces, with the cheeks and nose (36.4% each) being the most frequent sites of involvement. The mean time between laser treatment and hospital visits was 30.9 months, and six patients (54.5%) were diagnosed with BCC within 1∼5 years after laser ablation. Of the 11 patients, six were treated by dermatologists, two by non-dermatologists, and two by non-licensed personnel. Nine patients showed at least one classic dermoscopic pattern, and the most common dermoscopic finding was the presence of multiple blue/gray globules (7/10, 70.0%). No recurrence after wide excision was observed during the last follow-up. Conclusion Despite dermoscopic examination reimbursement, our findings indicate that approximately 10.0% of BCCs are still misdiagnosed as benign lesions, as reported in a previous study. Therefore, when a malignancy is suspected, dermoscopic examination and biopsy should be considered to ensure an accurate diagnosis and facilitate appropriate treatment.

Purpose: This study evaluated the clinical outcomes and prognostic factors in patients with borderline resectable pancreatic cancer (BRPC) and locally advanced pancreatic cancer (LAPC) treated with upfront FOLFIRINOX followed by local-regional therapy (LRT), surgical resection (SR), and radiotherapy (RT). We aimed to identify specific patient subgroups for which RT may serve as a reasonable alternative to SR for local tumor control. Methods: We retrospectively analyzed 116 patients (SR group, n= 70; RT group, n= 46) at a single center between 2015 and 2020. Survival outcomes were compared based on LRT modalities, focusing on identifying subgroups in which RT provided an efficacy comparable to that of SR. Results: Among 116 patients, the SR group achieved a significantly higher 5-year overall survival (OS) than the RT group (27.1% vs. 8.7%, P< 0.0001), despite similar progression-free survival (P= 0.23). Significant prognostic factors for OS included carbohydrate antigen 19-9 (CA19-9) response in BRPC (P= 0.02) and radiologic partial response in LAPC (P= 0.05). Subgroup analysis revealed that, while SR provided a survival advantage in CA19-9 responders, no significant difference in OS was observed between SR and RT in CA19-9 non-responders (P= 0.37). Conclusion Although surgery remains the gold standard, RT may be considered a justifiable local alternative for CA19-9 non-responders and surgically ineligible patients with LAPC, yielding comparable outcomes in these specific, biologically unfavorable subgroups.

Objectives: 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. 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 5460 ESD cases from 5250 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.

Background/Aims: Endoscopic anti-reflux therapy is a therapeutic option for gastroesophageal reflux disease (GERD), providing durable effects. However, clinical data from Korea remain limited. This study evaluates the clinical outcomes of endoscopic radiofrequency Stretta therapy in Korean patients. Methods: A retrospective analysis was conducted on 71 patients with GERD who underwent Stretta therapy at 2 tertiary hospitals in Korea between November 2015 and July 2021. Clinical outcomes, including patient satisfaction, medication cessation or reduction, and complications, were evaluated. Pre- and post-procedural esophageal manometry and 24-hour pH monitoring test results were also analyzed. Results: Patient satisfaction rates at 1, 6, and 12 months post-procedure were 54.7% (35/64), 70.0% (28/40), and 75.0% (21/28), respectively. Medication cessation or reduction was achieved in 31.2% (20/64) at 1 month, 70.0% (28/40) at 6 months, and 67.9% (19/28) at 12 months. Esophageal manometry (n = 21) showed no significant changes in mean lower esophageal sphincter pressure (18.7 mmHg [2.5-52.9] vs 17.4 mmHg [0.0-43.0], P = 0.702) or mean integrated relaxation pressure (8.2 mmHg [0.0-28.0] vs 10.1 mmHg [0.0-31.0], P = 0.840). The 24-hour pH monitoring (n = 18) demonstrated a nonsignificant decrease in acid exposure time (pH < 4) from 2.3% (0.0-8.4) to 1.6% (0.0-7.3) (P = 0.182). Similarly, the DeMeester score decreased non-significantly from 8.4 (0.8-27.7) to 6.6 (0.8-21.8) (P = 0.352). No procedure-related complications occurred. Conclusion Endoscopic radiofrequency Stretta therapy appears to be a safe treatment option for GERD and may provide favorable patient satisfaction and medication reduction.

Sparganosis is a rare parasitic infection caused by Spirometra species. Although it was relatively common in the past, it is now often overlooked. In this study, we review cases diagnosed through histopathological examination at a single institution in recent years to raise awareness of this neglected parasitic disease. Methods: We retrospectively analyzed cases of human sparganosis identified in the pathology archives of a single institution in South Korea between 2004 and 2025. A comprehensive review was conducted, including demographic data, clinical features, lesion locations, imaging findings, exposure history (such as dietary habits), and histopathologic findings. Results: A total of 15 patients were identified, including 10 females and 5 males, with a mean age of 65.1 years. Lesions were most commonly located in the lower extremities and breast. Imaging findings were largely nonspecific, with ultrasonography being the most frequently used modality. In most cases, clinical suspicion of sparganosis was absent, and excision was performed under the impression of a benign or malignant tumor. Histologically, variably degenerated parasitic structures were identified within granulomatous inflammation. However, preserved features such as calcospherules and tegumental structures facilitated definitive diagnosis. Conclusions: This study underscores the importance of recognizing the characteristic histopathological features of sparganosis, which can allow for accurate diagnosis even in the absence of clinical suspicion. Although rare, sparganosis remains a relevant diagnostic consideration in endemic regions, particularly in East Asia.
