Background: This study was performed to evaluate the prognostic utility of a positive T wave in lead augmented vector right (TaVR) and elevated E/e′ ratio in predicting major adverse cardiovascular events (MACE) in patients receiving maintenance hemodialysis. Methods: We retrospectively examined 296 adults on thrice-weekly hemodialysis with baseline electrocardiography and transthoracic echocardiography (October 2018–April 2024). TaVR positivity was T-wave amplitude, >0 mV and high E/e′, ≥19. Primary outcome was the first MACE—cardiovascular death, myocardial infarction, stroke, heart-failure admission, or revascularization. Multivariable Cox models adjusted for clinical covariates; incremental value was gauged with Harrell’s C-index, integrated discrimination improvement (IDI), and continuous net reclassification improvement (NRI). Sensitivity analysis was performed using a guideline-recommended E/e′ threshold of ≥15 to assess robustness. Results: Over 56.5 months (1,325 patient-years), 118 MACE occurred (8.9/100 patient-years). Incidence was higher with TaVR positivity than negativity (16.0/100 patient-years vs. 3.7/100 patient-years; log-rank p < 0.001). Adjusted hazard ratios were 3.19 (95% confidence interval [CI], 2.00–5.08) for TaVR and 2.92 (95% CI, 1.71–4.96) for high E/e′. Adding both markers to the clinical model increased the C-index from 0.65 to 0.75 (Δ 0.10) and improved IDI (0.10) and NRI (0.16) (all p < 0.01). A significant negative interaction (hazard ratio, 0.21; p = 0.01) indicated complementary but partly overlapping information. Sensitivity results were similar. Conclusion TaVR positivity is a strong independent electrocardiography predictor of cardiovascular events in hemodialysis. Combining TaVR with E/e′ adds prognostic value and supports a pragmatic two-step strategy— electrocardiography triage followed by focused echocardiography—for cardiovascular risk stratification in this high-risk population.

Purpose: Many breast cancer patients experience genitourinary syndrome of menopause (GSM) symptoms. Concerns about systemic absorption limit the use of local estrogen therapy, and clinicians are often hesitant to prescribe it to breast cancer survivors.Therefore, other treatment options are essential. The aim of this study was to examine the safety and effectiveness of fractional CO2 laser treatment in breast cancer survivors experiencing GSM. Materials and Methods: Each woman received three fractional CO2 treatments at 4-week intervals between sessions: baseline (V1), 4-week follow-up (V2), 8-week follow-up (V3), and a final follow-up at 12 weeks (V4). Breast cancer survivors who had one or more symptoms related to GSM qualified for inclusion in this study. Severity of symptoms was assessed with a visual analog scale (VAS) at baseline and every follow-up visit. We also measured GSM objectively using the vaginal health index score (VHIS) at every visit. At V4, patients evaluated their satisfaction with laser therapy using a 5-point Likert scale. Results: Twenty-four women were included in the study. Almost all symptoms showed improvement based on mean VAS score after treatment. Vaginal dryness and urgency improved after the second treatment. After completion of all treatments, all symptoms except frequency showed improvement. VHIS increased significantly after completion of laser treatment (8.5±3.1 at baseline vs. 16.2±2.9 at V4; p<0.001). Conclusion Fractional CO2 laser treatment appears to be an effective and safe method in breast cancer survivors with GSM.

With the increasing emphasis on diversity, equity, and inclusion (DEI) in organizations and institutions, academic societies in gastroenterology and hepatology are beginning to take actionable steps toward achieving DEI. The successful implementation of DEI initiatives leads to excellence in the field, improved patient outcomes, particularly in areas where health disparities are prevalent, and advances in the gastrointestinal discipline. Such implementation also results in a workforce that better reflects the growing diversity of the population. This review defines DEI and introduces the DEI policies and strategies adopted by the academic societies of gastroenterology in other countries. This paper proposes strategies to integrate DEI better into the Korean Society of Gastroenterology, emphasizing the importance of embedding DEI into the culture and strategic framework. The key strategies include establishing a DEI committee, setting clear targets, and conducting formal assessments to measure DEI progress. This study focused on enhancing workforce diversity, particularly among women and young doctors, and advocates for the need to support their academic development through male allyship and the promotion of equitable and inclusive academic cultures.

Purpose: Biliary atresia (BA) is a rare but progressive cholangiopathy and the leading cause of pediatric liver transplantation worldwide. The Korean Association of Pediatric Surgeons (KAPS) has conducted three national surveys (2001, 2011, and 2023) to assess long-term trends in the diagnosis, treatment, and outcomes of BA. This study provides a comparative analysis of the 2nd and 3rd national surveys, with reference to selected findings from the 1st survey. Methods: This study included 453 patients from the 3rd national survey (2011–2021) and 435 patients from the 2nd survey (2001–2010), all of whom underwent Kasai portoenterostomy. Data were collected via electronic case report forms from pediatric surgical centers nationwide. Comparisons were made regarding demographics, clinical features, diagnostic patterns, operative details, follow-up outcomes, and survival. Kaplan–Meier analysis was used to evaluate long-term survival. Results: The mean number of BA patients per year remained stable between surveys (43.5 in the 2nd, 41.18 in the 3rd), though centralization of care increased, with 61.5% of cases managed by two major institutions in the 3rd survey. The median age at surgery decreased, and the use of preoperative imaging (especially magnetic resonance cholangiopancreatography) increased. The 10-year native liver survival rate declined from 59.8% to 53.7%, while overall 10-year survival improved slightly (92.9% to 93.2%). Postoperative complications, such as cholangitis and liver failure, persisted but were better categorized. The 3rd survey also reported improved mortality (4.9%) and reduced follow-up loss (11.5%) compared to the 2nd survey. Conclusion While overall survival after Kasai operation has remained high and even improved, native liver survival has slightly declined. The findings reflect earlier diagnosis, more consistent diagnostic imaging, and increasing centralization of care. These trends underscore the importance of long-term nationwide data collection in guiding future strategies for BA management in Korea.

Purpose: This study aims to investigate and compare the incidence, demographic characteristics, clinical manifestations, preoperative diagnostic methods, anatomical classifications, associated anomalies, operative treatments, and postoperative outcomes of patients with intestinal atresia treated by the members of the Korean Association of Pediatric Surgeons (KAPS) through three nationwide surveys. Methods: KAPS conducted 3 national surveys in 1998, 2010, and 2024 to examine the patients diagnosed with intestinal atresia. In preparation for the survey, we developed a customized case registration form to obtain data on patient sex, birth weight, gestational age, clinical manifestations, preoperative diagnostic methods, anatomical types, associated anomalies, operative treatments, and postoperative outcomes. Authorized KAPS members completed the case registration form. Results: The first, second, and third national surveys included 218, 222, and 236 individuals diagnosed with intestinal atresia, respectively. The male-to-female ratios were 1.5:1, 1.1:1, and 1.1:1, respectively. The first, second, and third national surveys revealed that 34.3%, 43.3%, and 53.4% of patients were born before 37 weeks of gestation, respectively. Additionally, 28.7%, 32.0%, and 40.7% of patients had a birth weight under 2,500 g. In the third national survey, duodenoduodenostomy was the most common procedure, performed in 70 out of 82 patients diagnosed with duodenal atresia. Resection and anastomosis were the main surgical procedures conducted in 47 out of 54 cases of jejunal atresia and 74 out of 92 cases of ileal atresia. The mortality rates in the first, second, and third national surveys were 13.8%, 3.6%, and 1.3% respectively, with the lowest rate observed in the third national survey. Conclusion These national surveys offer valuable insights into the current state of intestinal atresia, including specific surgical interventions and postoperative outcomes in South Korea. For pediatric surgeons aiming to enhance their understanding of intestinal atresia and its treatment options, these surveys could be an indispensable resource and guide.

Antiviral therapy is an essential treatment for chronic hepatitis B (CHB) infection. Although hypophosphatemia is an important adverse effect of antiviral agents, its clinical significance remains unclear. We investigated the incidence and clinical consequences of hypophosphatemia in a large cohort of CHB patients. Methods: This retrospective cohort study included CHB patients who started antiviral therapy between 2005 and 2015 and continued it for at least 1 year. Patients with decompensated liver cirrhosis, diabetes mellitus, hypertension, concomitant diuretic administration, and end-stage renal disease were excluded. The primary outcome was a change in renal function. Secondary outcomes included the incidence of infection and changes in serum potassium, uric acid, and total carbon dioxide (tCO2). Results: Among the 4,335 patients, hypophosphatemia developed in 75 (1.7%). During the median 2-year follow-up period, patients with hypophosphatemia showed a lower estimated glomerular filtration rate than those in the control group. The incidence of infection and changes in serum potassium, uric acid, and tCO2 were similar between groups. Conclusion: Hypophosphatemia was associated with a renal function decline in patients with CHB receiving antiviral therapy.
