INTRODUCTION/BACKGROUND:Some living organ donors will decide to donate again at a later date. Evidence has indicated that this practice may have increased in recent years. We evaluated the incidence and outcomes of this practice to inform counseling of potential repeat donors. METHODS:Using SRTR data from 1994 to 2023, we identified 220 repeat living donors and their 415 recipients. We constructed donor comparison groups using weighting by the odds. We described clinical and lab results at 6 months, 1 year, and 2 years post-donation separately for kidney-second donors and liver-second donors. We compared all-cause graft failure for their recipients with those of comparison donors. RESULTS:The annual count of repeat living donors increased from 5 in 2018 to 25 in 2019 (p < 0.001). Of 220 donors, 159 were liver-second donors (72.3%) and 55 were kidney-second donors (25.0). The percentage of nondirected donations increased from 30.5% at first donation to 53.2% at second donation (p < 0.001). Liver-second donors had one death approximately 2.5 years post-donation. Seventeen were re-admitted and 20 experienced complications requiring an interventional procedure or re-operation. Among kidney-second donors, no deaths, re-admissions, or post-donation complications were reported. Post-donation outcomes in both groups were comparable when evaluated against organ-specific comparison donors. Recipients of repeat living donors experienced graft survival similar to recipients of comparison donors. CONCLUSIONS:Repeat living donation may be a safe practice for carefully selected living donors in the short term; however, long term safety is unknown. Outcomes for recipients are similar to recipients of comparison donors.

Use of normothermic regional perfusion (NRP) to enable organ reconditioning and assessment in donation after circulatory determination of death (DCD) is controversial. We conducted a scoping review of peer-reviewed articles, news media, legal literature, and professional society position statements addressing ethical and/or legal issues in use of NRP in controlled DCD from January 1, 2005 to January 5, 2024. Thematic analysis, assessing the four principles of bioethics (autonomy, beneficence, non-maleficence, and justice) and sub-themes identified within each, was conducted for the 112 publications meeting inclusion criteria. More than 30 publications addressed the topic in each of 2022 and 2023, versus ≤6 per year previously. Non-maleficence was the most frequently addressed bioethical principle (111/112 publications), and most varied, with 14 subthemes. Attitudes towards NRP differed by type of NRP: Of 72 publications discussing thoracoabdominal NRP, 22 (30.6%) were 'In Favor', 39 (54.2%) 'Neutral', and 11 (15.3%) 'Against'; of 44 discussing abdominal NRP, 23 (52.3%) were 'In Favor', 20 (45.5%) 'Neutral', and 1 (2.3%) 'Against'. Attitudes differed by authors' country, degree, and affiliation, and by clinical focus of the publishing journal. Overall, our review shows the ethical and legal issues raised by NRP remain unresolved, and debate centered on non-maleficence.

Artificial intelligence (AI) is rapidly transforming healthcare, and the field of kidney transplantation (KT) is no exception. While much of the AI-related work has focused on deceased donor KT, there is a growing body of research applying AI tools to living kidney donation (LKD). This review explores AI's current and potential roles in LKD, focusing on predictive and social applications of AI in LKD. Additionally, we discuss the challenges and limitations of implementing AI in clinical settings and highlight emerging research trends. This review consolidates existing research and provides a foundation for both transplant professionals and data scientists seeking to integrate AI responsibly into living donor programs.

BACKGROUND:Pretransplant functional, motor, cognitive, and academic deficits are common in pediatric patients requiring heart transplantation (HT); some persist post-HT. We assessed the association between these quality of life (QoL) deficits and post-HT outcomes. METHODS:Using SRTR data 2008-2023, we evaluated the functional, motor, cognitive, and academic status of pediatric HT recipients from listing to 15 years post-HT. We compared all-cause graft survival among patients with vs. without pre-HT deficits using Cox regressions. Among patients with a functioning graft at 1 year, we assessed the association between deficits at that time and subsequent graft failure. RESULTS:, p < 0.001). CONCLUSION/CONCLUSIONS:Pediatric HT recipients with decreased functional status are at higher risk for graft failure and mortality. These patients may benefit from early intervention aimed at improving functional status.

In 2022, an interdisciplinary team of subject matter experts was convened to substantially revise the Mass Media sector content of the National Physical Activity Plan. The updated version recognizes the rapid pace at which the media landscape is evolving and includes a new sector name (Media and Communications) and revised strategies and tactics that reflect progress in the development of a national physical activity campaign brand (Move Your Way ®). This commentary summarizes key changes and highlights the importance of ongoing collaboration between physical activity and media professionals to optimize promotion of physical activity through diverse channels.

INTRODUCTION/BACKGROUND:ChatGPT has shown the ability to answer clinical questions in general medicine but may be constrained by the specialized nature of kidney transplantation. Thus, it is important to explore how ChatGPT can be used in kidney transplantation and how its knowledge compares to human respondents. METHODS:We prompted ChatGPT versions 3.5, 4, and 4 Visual (4 V) with 12 multiple-choice questions related to six kidney transplant cases from 2013 to 2015 American Society of Nephrology (ASN) fellowship program quizzes. We compared the performance of ChatGPT with US nephrology fellowship program directors, nephrology fellows, and the audience of the ASN's annual Kidney Week meeting. RESULTS:Overall, ChatGPT 4 V correctly answered 10 out of 12 questions, showing a performance level comparable to nephrology fellows (group majority correctly answered 9 of 12 questions) and training program directors (11 of 12). This surpassed ChatGPT 4 (7 of 12 correct) and 3.5 (5 of 12). All three ChatGPT versions failed to correctly answer questions where the consensus among human respondents was low. CONCLUSION/CONCLUSIONS:Each iterative version of ChatGPT performed better than the prior version, with version 4 V achieving performance on par with nephrology fellows and training program directors. While it shows promise in understanding and answering kidney transplantation questions, ChatGPT should be seen as a complementary tool to human expertise rather than a replacement.
