Transplantation Direct - May 2022 Issue


The May issue of Transplantation Direct covers a wide variety of medical, scientific and ethical topics in transplantation. In kidney transplantation, there are articles on robot assisted versus open procedure surgery outcomes, a proteomics-based approach to detect acute rejection in a Phase III multicenter trial, affects of HLA homozygosity on sensitization likelihood, detecting suboptimal outcomes using the kidney donor profile index, and the cost-effectiveness of polyomavirus screening in transplant recipients. Studies in liver transplantation are presented related to outcomes using pediatric donor organs in adult recipients, to the impact of the recent MMaT policy on transplant waitlist outcomes for HCC patients, and to “textbook outcomes" using UNOS data as a quality metric. In pancreas and islet transplantation, the use of dd-cfDNA to detect rejection in simultaneous pancreas and kidney transplant recipients is evaluated, and a novel – simple - technique is tested for islet isolation in the intra-operative setting of total pancreatectomy with islet-auto-transplantation. Other articles look at PBMC separation idiosyncrasies in transplant recipient patients, as well as review public understanding of the definition and determination death, and characterize industry-related payments to transplant surgeons using data from the “Open Payments Program". Please visit our open access Transplantation Direct website for full details on all of these articles.

Donor-specific Cell-free DNA as a Biomarker in Solid Organ Transplantation. A Systematic Review #TBT

There is increasing interest in the use of noninvasive biomarkers to reduce the risks posed by invasive biopsy for monitoring of solid organ transplants (SOTs). One such promising marker is the presence of donor-derived cell-free DNA (dd-cfDNA) in the urine or blood of transplant recipients.

Procurement of Deceased Donor Parathyroid Glands With the Aid of Near-infrared Autofluorescence Imaging #OpenAccess #TransplantTwitter

Parathyroid allotransplantation is a burgeoning treatment for severe hypoparathyroidism. Deceased donor parathyroid gland (PTG) procurement can be technically challenging due to lack of normal intraoperative landmarks and exposure constraints in the neck of organ donors. In this study, we assessed standard 4-gland exposure in situ and en bloc surgical techniques for PTG procurement and ex vivo near-infrared autofluorescence (NIRAF) imaging for identification of PTGs during organ recovery.

Selected medical students will participate in three workshops by asking questions to the panelists. Additionally, students will attend five other sessions of their choice, and special events, and will participate in TTS 2022 social media activity. Students will be mentored to develop a slide deck presentation with highlights of the sessions attended. Their experience at the Congress, as well as key take-home messages, will be shared with their medical school peers. Their slide decks and other materials from the congress will be featured on the TTS website.
