Kidney Transplant Populations at High Risk for Allograft Loss Identified

March 16 Article in Renal & Urology News Highlighting Recent Publication in Transplantation DIrect

Investigators have identified 2 distinct populations at high risk for graft loss after kidney transplantation. Risk factors at baseline suggest approaches to management, according to investigators.

Among 5752 solitary kidney transplants performed 2006-2018, graft loss occurred in 21.6% of patients, including 9.6% with graft failure and 12.0% with death with a functioning graft (DWFG).

How a game-changing transplant could treat dying organs

Early success with a procedure called a mitochondrial transplant offers a glimmer of hope for people fighting for survival after cardiac arrest, stroke, and more.

Young Stroke Victims' Hearts Might Not Be as Good for Transplantation

by Crystal Phend, Contributing Editor, MedPage Today March 14, 2022

UNOS data suggest interaction by age and mode of brain death

Hearts donated after death from stroke presented a higher mortality risk to the recipient if the donor was under age 40, a study showed.

In terms of recipient mortality, an analysis of the United Network for Organ Sharing (UNOS) registry showed no overall effect of stroke as a cause of donor brain death on outcomes, similar to what other contemporary series have shown.

However, there was more to it, with a "nonintuitive" interaction by donor age (P=0.008), reported Shinobu Itagaki, MD, MSc, of Mount Sinai Medical Center in New York City, and colleagues in the Journal of the American College of Cardiology.

3D Planning Cut Post-Op Complications in Kids' Liver Transplants

by Zaina Hamza, Staff Writer, MedPage Today March 15, 2022

— But little effect on graft, patient survival rates

Use of advanced preoperative 3D planning for pediatric liver transplant patients receiving larger grafts was associated with lower risk of postoperative complications, a small retrospective study in Taiwan found.

What Happens in the Brain When an Organ Transplant is Rejected?

By Christian Thorsberg - Discover - Mar 14, 2022 8:00 AM

— The brain-organ connection is complex. Here’s what surgeons look for before, during and after a transplantation.

Livers outnumber people in Catherine Kling’s operating room at the University of Washington Medical Center. On this particular day, the extra organ — the only one ex-vivo, cleaned and sitting on ice — arrived just hours before the transplantation, the culmination of a thoughtful and time-consuming process of diagnoses, donor locating, evaluations and transportation, all sequenced by many expert pairs of eyes and hands.

NEW! TTS Research Grants Program

TTS will provide funding to three individual investigators to support their research in transplantation. The spectrum of studies includes basic, clinical/epidemiological and translational. This individual should have spent five years or less performing research in transplantation (and/or immunology relating to transplant) since obtaining their last doctoral degree (PhD, MD, PharmD, or equivalent). One of these research grants will be preferentially designated to TTS members from a low- or middle-income country.
General Information
  1. The three seeding grants, at $25,000 each, will provide support to clinical, basic and translational scientists working within the field of transplantation. Research must commence on September 1st 2022 and conclude on 31st October, 20, 2024.

  2. Up to $25k per year for up to 2 years with requirement for annual reporting. The extra 2 months is intended to provide buffer for start-up, i.e. 14 months first period and 12 months second period

  3. The research start date cannot be deferred for any reason.

  4. Applications must be submitted in full by June 1st 2022 in order to be reviewed.

  5. The recipient will sign a letter of agreement with TTS. Payments will be issued to the recipient’s institution by TTS, and the recipient will report to the TTS Research Grant Committee.
Research Focus
The 2022 TTS Research Grant will fund research that encompasses epidemiologic, clinical, translational, and basic studies as well as studies to expand access to transplantation, including, but not limited to: Improving global access to transplantation and outcomes of transplantation.

Early in his career, Dr. Starzl recognized the importance of deceased donation. He pioneered many facets of transplantation, including immunosuppressive drug development, organ preservation, tissue matching, surgical transplant technology, and developed the team approach to organ transplantation; thus paving the way for the success and acceptance of heart, lung, pancreas, intestinal, liver, and kidney transplantation. The international impact of the fruits of seven decades of commitment to transplantation is shown by estimates of over 600 000 Americans and millions of patients around the world that have received a life-saving organ transplantation. He was also credited as having trained over 1,000 medical and surgical transplant specialists over his 50 years in clinical medicine, many of whom have gone on to successfully develop their own transplant
