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: Overactive bladder (OAB) symptoms may improve following surgical correction of cystocele. This study aimed to evaluate changes in urgency, the primary symptom of OAB, and identify factors associated with improvement in urgency after surgical treatment for cystocele. Methods: We conducted a retrospective analysis of medical records for patients who underwent surgical treatment for cystocele and had preoperative urgency measuring ≥3 on a 5-point urinary sensation scale. Patients were categorized into 2 groups based on their urgency status 3 months postsurgery: those with improved urgency and those without improvement. Improvement was defined as a reduction of 2 or more points on the scale following surgery. We compared preoperative clinical and urodynamic factors between the 2 groups. Results: A total of 137 patients were included in the study, with 98 (71.5%) showing improvement in urgency symptoms after surgery. The improved group had a significantly higher prevalence of preoperative urgency urinary incontinence (UUI) (62.2% vs. 30.8%, P=0.001) and bladder outlet obstruction (43.9% vs. 20.5%, P=0.011) compared to the nonimproved group. Urodynamic evaluations indicated that the detrusor pressure at maximum flow rate (PdetQmax) was significantly higher in the improved group than in the nonimproved group (P=0.004). Multivariate logistic regression analysis identified preoperative UUI, higher PdetQmax, and lower vaginal parity as independent predictors of improvement in urgency postoperatively. Conclusions Preoperative UUI, higher PdetQmax, and lower vaginal parity were significant predictors of postoperative improvement in urgency. Both clinical and urodynamic factors may help identify patients with cystocele and preoperative urgency who are most likely to benefit from anatomical correction.

Background: Left bundle branch block (LBBB) significantly increases the risk of left ventricular systolic dysfunction (LVSD) due to cardiac dyssynchrony. Although artificial intelligence–enabled electrocardiography (AI-ECG) mod‑ els show promise in detecting LVSD, their performance in LBBB patients remains underexplored. We hypothesized that an AI-ECG model clinically validated for detecting LVSD would accurately detect LVSD and predict future clinical outcomes in LBBB patients. Methods: In this retrospective multicenter study, 5,689 expert-validated LBBB ECGs collected from 2,813 patients between 2016 and 2024 were analyzed using a previously developed and validated AI-ECG model. LVSD was defined as an ejection fraction of ≤ 40%. Model performance was assessed using the area under the receiver operating char‑ acteristic curve (AUROC), the area under the precision-recall curve (AUPRC), sensitivity, and specificity. Patients were stratified into high- and low-risk groups based on a threshold that achieved 90% sensitivity. A Kaplan–Meier analysis was used to compare clinical outcomes. Results: Among the 2,813 LBBB patients (mean age, 70.7 years; male sex, 43.7%), hypertension and a history of heart failure were common. The AiTiALVSD model showed strong diagnostic performance for LVSD (AUROC, 0.930 [95% CI, 0.924–0.937]; AUPRC, 0.913 [95% CI, 0.902–0.923]; sensitivity, 0.979; specificity, 0.473). During the mean follow-up of 4.1 years, high-risk patients had significantly higher hazards than low-risk patients for all-cause mortality (adjusted hazard ratio [HR], 1.87; 95% CI, 1.53–2.28), implantable cardioverter defibrillator/cardiac resynchronization therapy implantation (adjusted HR, 15.2; 95% CI, 7.51–30.77), and cardiovascular hospitalization (adjusted HR, 1.11; 95% CI, 0.96–1.28). Conclusions AiTiALVSD effectively detects LVSD and stratifies long-term cardiovascular risk in LBBB patients, support‑ ing its clinical utility for early detection and patient management.

Objectives: This study aimed to analyze the level of job satisfaction and burnout among dental hygienists in Jeju Province and the relationship between them to provide baseline information for the improvement of the work environment and prevention of burnout. Methods: A 60-question online survey was distributed to dental hygienists working in dental institutions in Jeju. A total of 143 responses were obtained. Statistical analyses were performed using IBM SPSS Statistics (version 23), and statistical significance was set at P<0.05. The analysis methods included frequency analysis, descriptive statistics, Student’s t-test, one-way ANOVA, nonparametric tests such as the Mann–Whitney U-test and Kruskal–Wallis test, correlation analysis, and multiple regression analysis. Results: The scores for job satisfaction and burnout were 3.26±0.58 and 3.06±0.40 points, respectively, out of Likert 5 points. Job satisfaction was significantly different according to the type of medical institution, intention to change jobs, position, and age. Particularly, participants in their 40s had higher job satisfaction than those in their 30s. Job burnout was significantly higher in the group that intended to change jobs. Job satisfaction and burnout showed a significant negative correlation, whereas turnover intention showed a negative correlation with job satisfaction and a positive correlation with job burnout. Conclusions The factors influencing job satisfaction among dental hygienists in Jeju were a higher education level and intention to change jobs. In addition, the intention to change jobs influenced job burnout. Future follow-up studies with larger sample sizes are needed.

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.

Objectives: Management strategies for subepithelial lesions (SELs) measuring 1–2 cm remain undefined in most guidelines due to limited data. We aimed to establish a practical clinical approach by analyzing the long-term outcomes of SELs in this size range. Methods: We retrospectively reviewed cases of gastric SELs measuring 1–2 cm between 2011 and 2023. We reviewed esophagogastroduodenoscopy and endoscopic ultrasound images, alongside data from abdominal computed tomography, biopsy results, and long-term follow-up records. Results: Gastric SELs were initially identified in 648 patients. Of these, 88 patients (mean age, 57.1±10.6 years; 60% women) had lesions measuring 1–2 cm and underwent further evaluation or surveillance. The mean lesion size determined by endoscopy was 13.7±3.3 mm. Among the 52 patients with histological confirmation, 24 (46%) were diagnosed with gastrointestinal stromal tumors (GISTs), whereas the remainder had benign lesions. Most gastric SELs were located in the fundus and upper body. Pathological analysis indicated that the majority of GISTs were low-risk. Three GISTs were stratified as moderate-to-high risk; notably, one measured 0.9 cm upon pathological examination. The median surveillance period for the 28 patients without histological confirmation was 55 months (range, 43–115 months). Two of these patients underwent endoscopic or wedge resection due to tumor enlargement; both lesions were histologically confirmed as low-risk. Conclusions Approximately half of the gastric SELs measuring 1–2 cm were GISTs, representing an intermediate- to high-risk tumors. Given that GISTs in the upper stomach were associated with elevated risk even when smaller than 2 cm, we recommend strict short-term surveillance for such lesions.

Purpose: To evaluate the clinical characteristics, etiologies, and treatment outcomes of pediatric macular holes (MHs). Methods: The medical records of pediatric patients under 18 years of age diagnosed with MHs at Severance Hospital between January 2005 and December 2022 were retrospectively reviewed. Data regarding etiology, MH diameter, treatment methods, and both visual and anatomical outcomes were analyzed. Results: Among 15 patients (16 eyes), traumatic MHs were identified in 7 cases (46.7%), while non-traumatic causes included Stargardt disease, familial exudative vitreoretinopathy, and vitreomacular traction. No statistically significant differences were observed between the traumatic and non-traumatic groups in terms of age, MH diameter, or initial and final best-corrected visual acuity (BCVA). However, there was a significant difference in sex distribution, with all traumatic cases occurring in males, whereas only 3 of the 9 non-traumatic eyes were male (p = 0.01). Surgical intervention was performed in 13 eyes, achieving anatomical closure in 62.5% (10 eyes). The three eyes without closure (37.5%) were all non-traumatic cases. BCVA (logMAR) significantly improved from a median of 1.00 preoperatively to 0.70 postoperatively (p = 0.013). Among the three eyes that did not undergo surgery, one demonstrated spontaneous closure, and another achieved closure following medical treatment. Conclusions Pediatric MHs may arise from various ocular conditions beyond trauma. Surgical intervention was effective, particularly for traumatic MHs, while non-traumatic cases demonstrated a lower closure rate. In some instances, spontaneous or medically induced closure occurred without surgical management. Further multicenter studies with larger cohorts are warranted to establish definitive management guidelines for pediatric MHs.

Background/Aims: Helicobacter pylori may protect against immune-mediated disorders such as inflammatory bowel disease (IBD) and asthma. This study evaluated whether eradication was associated with IBD and asthma in Korean children. Methods: Data were collected from the Korean National Health Insurance information on patients younger than 18 years and without a prior diagnosis of IBD or asthma from January 2007 to September 2020. Patients confirmed with H. pylori infection were divided into the eradication and non-eradication group. We compared the incidence of IBD and asthma in infected patients with an age, and sex-matched control group. Results: In total, 979,663 patients were selected based on the inclusion criteria and 2,779 patients were included based on the exclusion criteria. The occurrence of IBD in infected patients was statistically significant (p < 0.05) but there was no association of infection with asthma. There was no association with eradication and the development of IBD and asthma. The infected group had a shorter duration till diagnosis of IBD than the control group. Conclusions Our study found H. pylori infection to be associated with the development of IBD in children. However, eradication does not increase IBD and asthma in children.

Background: A novel botulinum toxin type A (Protoxin; Protox Inc.) has been developed. Objective: To evaluate the efficacy and safety of the newly developed Protoxin compared to the approved drug onabotulinumtoxinA (OBoNT) in moderate to severe glabellar lines. Methods: Adults with a glabellar line Facial Wrinkle Scale (FWS) score of 2 (moderate) or 3 (severe) were enrolled in the study. Subjects were randomized in a 1:1 ratio to receive either Protoxin or OBoNT. A total of 20 units of botulinum toxin was injected at five sites in the glabellar region (4 units at each site). FWS scores were assessed at baseline and at weeks 4, 8, 12, and 16 post-injection. The primary endpoint was the proportion of subjects at week 4 who had a reduction of 2 or more points in FWS and a final score of 0 (none) or 1 (mild). Results: A total of 274 subjects were randomized, of whom 78.1% were female. At week 4 post-treatment, the improvement rate of glabellar lines was 62.22% in the Protoxin group and 62.96% in the OBoNT group. The lower limit of the two-sided 95% confidence interval (−12.24%) exceeded the −15% margin, confirming the non-inferiority of the new drug. Safety profiles were comparable between the two groups. Conclusion Protoxin demonstrated efficacy and safety profiles comparable to those of OBoNT in the treatment of moderate to severe glabellar lines.
