Risks of bariatric surgery among patients with end-stage renal disease.
Pretransplant morbid obesity among patients with end-stage renal disease (ESRD) is a significant predictor of delayed access to transplant and inferior posttransplant patient and kidney allograft outcomes. In this study, the authors performed an analysis of perioperative safety of bariatric surgery in obese patients with ESRD using a national registry capturing greater than 95% of bariatric operations.

Immunization status at the time of liver transplant in children and adolescents.
In this research letter, the authors quantified the percentage of patients at Society of Pediatric Liver Transplantation centers who were up to date for their age on immunizations at the time of transplant, and determined whether demographic and clinical factors were associated with immunization status at the time of transplant. They concluded that further research is needed to understand barriers to immunization in the pediatric transplant population and called for novel tools that provide pretransplant vaccine education and enhance communication between primary care and subspecialty clinicians.

Acute care surgery for transplant recipients: a national survey of surgeon perspectives and practices.
This study is a survey of acute care surgeons (ACS) and transplant surgeons on their attitudes as to who would feel comfortable operating on transplant patients for nontransplant-related issues. The researchers conducted a national survey of ACS and transplant surgeons and obtained 230 ACS responses and 240 from transplant surgeons. While both ACS and transplant surgeons felt care is better at transplant centers and if the patient requires acute surgery they should be transferred to a transplant center, the ACS still felt comfortable operating and performing laparoscopy on transplant recipients.

Digital wings: innovations in transition readiness for adolescent and young adult transplant recipients.
This article reports on two multi-stakeholder symposia organized by The Johns Hopkins University School of Medicine on February 2, 2018, and January 11, 2019, to address the problem of high graft failure in adolescent and young adult solid organ transplant recipients. Additionally, data collected from recipients demonstrated a substantial gap in how this population uses technologies for health-related activities, alongside an increased interest in an app to help them manage their transplant.

Systematic review with meta-analysis on transplantation for alcohol-related liver disease: very low evidence of improved outcomes.
Under the hypothesis that, while liver transplantation for patients with alcohol-related liver disease (ALD) may improve mortality and relapse, findings will be limited by pre-specified causes of heterogeneity, researchers conducted a systematic review. Data from 10 studies comparing use of liver transplant in ALD to no-transplant was analyzed. Primary outcome of both was short- and long-term mortality and relapse. The results of the review indicate that liver transplantation for ALD patients suggests reduced mortality and relapse in heterogeneous, institution-specific populations. The authors note that, to understand efficacy of transplanting ALD, their research approach must change.

Association of pretransplant and posttransplant program ratings with candidate mortality after listing.
The Scientific Registry of Transplant Recipients (SRTR) is responsible for understandable reporting of program metrics, including transplant rate, waitlist mortality, and posttransplant outcomes. SRTR developed five-tier systems for each metric to improve accessibility for the public. In this study, the researchers investigated the associations of the five-tier assignments at listing with all-cause candidate mortality after listing, for candidates listed July 12, 2011-June 16, 2014.

Comparing Scientific Registry of Transplant Recipients posttransplant program-specific outcome ratings at listing with subsequent recipient outcomes after transplant.
To improve accessibility of program-specific reports to patients, the Scientific Registry of Transplant Recipients released a 5-tier system for categorizing 1-year posttransplant program evaluations. Whether this system predicts subsequent posttransplant outcomes at the time patients are waitlisted has been questioned. IN this study, researchers investigated the association of tier at listing and the corresponding continuous score used for tier assignment, which ranges from 0 (poor outcomes) to 1 (good outcomes), with eventual 1-year posttransplant graft survival.

Limited health literacy and adverse outcomes among kidney transplant candidates.
More than one-third of US adults have limited health literacy, putting them at risk of adverse clinical outcomes. In this study the investigators evaluated the prevalence of limited health literacy among 1578 adult kidney transplant (KT) candidates (May 2014-November 2017) and examined its association with listing for transplant and waitlist mortality in this pilot study. The investigators concluded that limited health literacy may be a salient mechanism in access to KT; programs to aid candidates with limited health literacy may improve outcomes and reduce disparities.

The association of preoperative cardiac stress testing with 30-day death and myocardial infarction among patients undergoing kidney transplantation.
This study examined whether the use of preoperative cardiac stress testing of patients undergoing kidney transplantation reduced 30-day- death and myocardial infarction post-transplantation. ESRD patients 40 years or older with primary Medicare insurance between 2006 and 2013 were identified using the United States Renal Data System. In a matched cohort of 17,304 patients, there was little difference in 30-day post-transplantation mortality and myocardial infarction between those receiving a stress test and those who did not.

The relationship between the C-statistic and the accuracy of program-specific evaluations.
The C-statistic of the risk-adjustment model is often used to judge the accuracy of program evaluations. However, the C-statistic depends on the variability in risk for individual transplants and may be inappropriate for determining the accuracy of program evaluations. This simulation study investigated the association of the C-statistic with several metrics of program evaluation accuracy, including categorizing programs into the 5-tier system and identifying programs for regulatory review.

Better graft outcomes from offspring donor kidneys among living donor kidney transplant recipients in the United States.
This study used Scientific Registry of Transplant Recipients data 2001-2016 to evaluate death-censored graft failure (DCGF) and mortality for recipients of offspring versus nonoffspring living donor kidneys, using Cox regression models with interaction terms. The investigators found that kidneys from offspring donors provided lower graft failure and comparable mortality.
