Purpose: Although some medications trigger the worsening of myasthenia gravis (MG), their clinical influence on patients with MG has not been significantly evaluated. We aimed to investigate whether the risk of clinical worsening of MG increases after administering cautionary drugs in patients with MG. Materials and Methods: This retrospective case-control study was based on the medical records of patients diagnosed with MG between 2007 and 2020. We analyzed the risk of MG worsening in patients exposed to cautionary drugs during the risk period, defined as 6 months from the first exposure to cautionary drugs. The risk of MG worsening in the exposed patients was compared to that in the non-exposed patients, who were individually matched in a 1:1 ratio with exposed cases for sex, age, thymoma, and autoantibodies. Results: Of the 2002 patients diagnosed with MG, 552 (27.6%) were exposed to cautionary drugs. Neuromuscular blocking agents (320 patients) and beta blockers (66123 person-days) were the most frequently prescribed medications. After exact matching, 220 exposed and 220 non-exposed patients were enrolled. The incidence rate of clinical worsening during the risk period was significantly higher in the exposed patients than in the non-exposed patients (odds ratio=4.09; 95% confidence interval, 1.88–8.90;p<0.001). Clinical worsening was observed in 31 (14.1%) of the exposed patients and in 8 (3.6%) of the non-exposed patients. Conclusion The administration of cautionary drugs increased the risk of clinical worsening in patients with MG. Clinicians should be aware of this risk when cautionary drugs need to be administered.

Purpose: Pancreas transplantation (PT) is a definitive treatment for diabetes mellitus (DM), restoring endogenous insulin secretion and improving glycemic control. Despite its efficacy, PT is less common in South Korea compared to Western nations. This study aims to report the clinical outcomes of PT over 2 decades at a single center, focusing on surgical techniques, complications, and graft survival. Methods: A retrospective analysis of 69 PT recipients at Seoul National University Hospital between January 2002 and December 2023 was conducted. Data on recipient and donor demographics, surgical details, immunosuppressive regimens, and graft outcomes were collected. Graft survival was evaluated using Kaplan-Meier analysis, with subgroup comparisons using the log-rank test. Graft failure was defined as graft removal, PT re-registration, insulin dependence exceeding 0.5 units/kg/day for more than 90 days, or patient death. Results: Among the 69 recipients, 50 (72.5%) had type 1 DM, and 18 (26.1%) had type 2 DM. Simultaneous pancreaskidney (SPK) transplantations comprised 84.1% (n = 58), and pancreas-after-kidney (PAK) transplantations accounted for 10.1%. The 1-year and 5-year death-censored pancreas graft survival rates were 92.7% and 89.6%, respectively, with no significant difference between SPK and PAK (P = 0.330). Graft failure occurred in 10 patients, primarily due to pancreatitis and rejection. Donor-related factors, particularly anoxic brain injury, were significantly associated with lower graft survival (P = 0.045). Conclusion PT outcomes in this cohort align with international standards, emphasizing the importance of donor selection and tailored immunosuppression. Expanding PT indications to include selective type 2 DM patients could benefit South Korea’s PT programs with adequate resource allocation.

Purpose: Since 1995, the Korean Gastric Cancer Association (KGCA) has been periodically conducting nationwide surveys on patients with surgically treated gastric cancer. This study details the results of the survey conducted in 2023. Materials and Methods: The survey was conducted from March to December 2024 using a standardized case report form. Data were collected on 86 items, including patient demographics, tumor characteristics, surgical procedures, and surgical outcomes. The results of the 2023 survey were compared with those of previous surveys. Results: Data from 12,751 cases were collected from 66 institutions. The mean patient age was 64.6 years, and the proportion of patients aged ≥71 years increased from 9.1% in 1995 to 31.7% in 2023. The proportion of upper-third tumors slightly decreased to 16.8% compared to 20.9% in 2019. Early gastric cancer accounted for 63.1% of cases in 2023.Regarding operative procedures, a totally laparoscopic approach was most frequently applied (63.2%) in 2023, while robotic gastrectomy steadily increased to 9.5% from 2.1% in 2014.The most common anastomotic method was the Billroth II procedure (48.8%) after distal gastrectomy and double-tract reconstruction (51.9%) after proximal gastrectomy in 2023.However, the proportion of esophago-gastrostomy with anti-reflux procedures increased to 30.9%. The rates of post-operative mortality and overall complications were 1.0% and 15.3%, respectively. Conclusions The results of the 2023 nationwide survey demonstrate the current status of gastric cancer treatment in Korea. This information will provide a basis for future gastric cancer research.

Heart failure (HF) is a major cause of mortality and morbidity in South Korea, imposing substantial physical, emotional, and financial burdens on patients and society. Despite the high burden of symptom and complex care needs of HF patients, palliative care and hospice services remain underutilized in South Korea due to cultural, institutional, and knowledge-related barriers. This position statement from the Korean Society of Heart Failure emphasizes the need for integrating palliative and hospice care into HF management to improve quality of life and support holistic care for patients and their families. By clarifying the role of palliative care in HF and proposing practical referral criteria, this position statement aims to bridge the gap between HF and palliative care services in South Korea, ultimately improving patient-centered outcomes and aligning treatment with the goals and values of HF patients.
