Barriers to pretransplant immunization: a qualitative interview study of pediatric solid organ transplant stakeholders.
Investigators described the experiences and beliefs of pediatric transplant stakeholders regarding factors that contribute to low pre-transplant immunization rates. Five central themes emerged: gaps in knowledge about timing and safety of pre-transplant immunizations; lack of communication, coordination, and follow-up between team members; lack of centralized immunization records; subspecialty clinics functioning as the medical home for transplant candidates, but not able to provide all needed immunizations; and differences between organ type in prioritization and completion of pre-transplant immunization. The authors recommended new tools to overcome these barriers and to increase immunization rates in transplant candidates.

A community divided: post-transplant live vaccine practices among Society of Pediatric Liver Transplantation (SPLIT) centers.
The goal of this study was to assess current post-transplant live vaccine practices at individual pediatric liver transplant centers following the updated AST guidelines. Using email surveys with a 93% response rate, findings showed that only 29% of centers offered live vaccines post-transplant, with each center using different eligibility criteria for live vaccines. The main reasons for a center not offering post-transplant live vaccines were safety concerns and inability to reach group consensus.

Impact of acuity circles on outcomes for pediatric liver transplant candidates.
In December 2018, UNOS approved an allocation scheme based on recipients' geographic distance from a deceased donor ("acuity circles"). Previous analyses suggested acuity circles (AC) would reduce waitlist mortality overall, but their impact on pediatric subgroups was not considered. In this study, the investigators applied Scientific Registry of Transplant Recipients data from 2011-2016 towards the Liver Simulated Allocation Model (LSAM) to compare outcomes by age and illness severity for the UNOS-approved AC and the existing Donor Service Area (DSA)/Region-based allocation schemes.

Determinants of length of stay after pediatric liver transplantation.
In this study, the investigators sought to identify factors that were associated with LOS following pediatric (<18 years) liver transplantation in order to provide personalized counseling and discharge planning for recipients and their families. They concluded that while center-level practices accounted for substantial variation in LOS, consideration of donor and recipient factors could help clinicians provide more personalized counseling for families of pediatric liver transplant candidates.

Projected 20- and 30-year outcomes for pediatric liver transplant recipients in the United States.
Researchers aimed to use national registry data and parametric models to project 20- and 30-year post-transplant outcomes for recently transplanted pediatric liver transplant (LT) recipients. Using Scientific Registry of Transplant Recipients data, they found that projected long-term outcomes for recently transplanted pediatric LT recipients are excellent, reflective of substantial improvements in medical care, and informative for physician-patient education and decision making in the current era.

Under-immunization of pediatric transplant recipients: a call to action for the pediatric community.
This article is a call to action for pediatric solid organ transplant recipients to receive their recommended immunizations. Vaccine-preventable infections (VIPs) occur in 1 in 6 pediatric transplant recipients and these hospitalizations result in significant morbidity, mortality, graft injury, and cost. There has been an increase in the overall population in non-medical vaccine exemptions, which reduces herd immunity and creates greater risk for patients undergoing or already having received transplants.

Utility of autopsy among pediatric allogeneic hematopoietic stem cell transplant recipients: one last chance to learn?
Researchers conducted a retrospective cohort study of children undergoing allogeneic hematopoietic stem cell transplant (HSCT) at Duke University who died of any cause in 1995 and 2016. They found no associations between autopsy performance and patient age, sex, HSCT indication, or HSCT donor. Additionally, the proportion of autopsies with an unexpected diagnosis did not change during the study period. The researchers conclude that the utility of autopsy in this patient population remains high despite a reduction in the identification of unexpected infections.

Fifteen-year trends in pediatric liver transplants: split, whole deceased, and living donor grafts.
This study evaluated changes in patient and graft survival for pediatric liver transplant recipients since 2002, and to determine if these outcomes vary by graft type (whole liver transplant, split liver transplant [SLT], and living donor liver transplant [LDLT]). It concluded that in recent years, outcomes after the use of technical variant grafts are comparable with whole grafts, and may be superior for LDLT.

Impact of race and ethnicity on outcomes for children waitlisted for pediatric liver transplantation.
This study sought to determine whether outcomes on the waitlist (ie, mortality, deceased donor liver transplantation [DDLT], and living-donor liver transplantation [LDLT]) varied by race/ethnicity. It concluded that, compared to Caucasian children, African-American children are less likely to use LDLT but have higher rates of DDLT and similar survival on the waitlist.
