Background: The Living Kidney Donor Profile Index (LKDPI) was developed in the United States to predict graft outcomes based on donor characteristics. However, there are significant differences in donor demographics, access to transplantation, proportion of ABO incompatibility, and posttransplant mortality in Asian countries compared with the United States. Methods: We evaluated the clinical relevance of the LKDPI score in a Korean kidney transplant cohort by analyzing 1860 patients who underwent kidney transplantation between 2000 and 2019. Patients were divided into three groups according to LKDPI score: <0, 1–19.9, and ≥20. Results: During a median follow‐up of 119 months, 232 recipients (12.5%) experienced death‐censored graft loss, and 98 recipients (5.3%) died. High LKDPI scores were significantly associated with increased risk of death‐censored graft loss independent of recipient characteristics (LKDPI 1–19.9: HR 1.389, 95% CI 1.036–1.863; LKDPI ≥20: HR 2.121, 95% CI 1.50–2.998). High LKDPI score was also significantly associated with increased risk of biopsy‐proven acute rejection and impaired graft renal function. By contrast, overall patient survival rates were comparable among the LKDPI groups. Conclusion: High LKDPI scores were associated with an increased risk of death‐censored graft loss, biopsy‐proven acute rejection, and impaired graft renal function among a Korean kidney transplant cohort.

Background: Considering the increasing possibility of emergency situations in dental clinics over time, we conducted this study to evaluate the changes in the knowledge and practical skills of students of dental school before and after retraining for 2 years after the initial education on basic life support (BLS) of the American Heart Association (AHA). Methods: All third-year students of dental school who had received the same education on BLS provider training of the AHA 2 years earlier were included in this study. Among them, 98 students were asked to answer a questionnaire about BLS knowledge and conduct a practical skills assessment of high-quality cardiopulmonary resuscitation using Little Anne QCPR before and after retraining. Results: After retraining, the level of BLS knowledge increased in all 7 categories, and BLS performance increased in all 19 subcategories. Comparison of the QCPR numerical data items before and after retraining showed that all items after retraining met the criteria recommended by the AHA. Conclusion: Students of dental school had low levels of knowledge and practical skills of BLS before retraining after 2 years from the initial education and had high levels after retraining. Therefore, BLS training must be updated periodically, and more effective education methods are required to maintain BLS knowledge and practical skills., Competing Interests: Competing Interests: The authors have declared that no competing interest exists., (© The author(s).)
