In organ transplantation, ischemia-reperfusion injury (IRI) has been implicated in delayed graft function (DGF) as well as in short- and long-term complications. Using an autotransplant pig kidney model, changes in renal function and morphology were determined after different periods of cold ischemia in kidneys preserved in the University of Wisconsin solution (UW), high-Na(+) version of UW (HEH) or Celsior (CEL) a newly developed high-Na(+) solution, with or without trimetazidine (TMZ). Kidney function was better preserved in CEL, UW and particularly HEH in combination with TMZ, particularly after 48 and 72 h. Mitochondria integrity was improved in TMZ-preserved groups. This study indicates that TMZ is efficiently protective against IRI even after prolonged preservation and in different preservation solutions.

Impact of Kidney Allocation System 250 Policy on One Year Graft Loss.

Thomas E. Starzl Transplantation Institute, Renal-Electrolyte Division, University of Pittsburgh Medical Center, Pittsburgh, PA. Electronic address:
A new deceased donor kidney allocation system (KAS250) was implemented in March 2021 that prioritizes recipients within a 250 nautical mile radius from the donor hospital. KAS250 was implemented to reduce geographic disparities in access to kidney transplantation. Studies have shown an increase in cold ischemia time (CIT) after KAS250 implementation but the impact on graft outcomes is unknown.

Posttransplant diabetes mellitus (PTDM) is associated with significant morbidity and mortality in liver transplant recipients (LTRs). We used the Organ Procurement and Transplantation Network (OPTN) database to compare the incidence of developing PTDM across the United States and develop a risk prediction model for new-onset PTDM using OPTN region as well as donor-related, recipient-related, and transplant-related factors. All US adult, primary, deceased donor, LTRs between January 1, 2007, and December 31, 2016, with no prior history of diabetes noted, were identified.

Prolonged cold ischemia time (CIT) and neoadjuvant chemotherapy (NACT) can each independently impact the expression of breast cancer-related biomarkers, but their combined effects are not well studied. Herein, we assessed whether prolonged CIT has a higher modulatory effect on post-NACT biomarker expression in breast cancer specimens than in otherwise similar but non-NACT specimens. Our study cohort included 334 biopsy/resection breast cancer specimen pairs in which immunohistochemistry (IHC for estrogen receptor [ER], progesterone receptor [PR], HER2) and HER2 FISH had been performed on both specimens.

Background: Donor livers from older donation after circulatory death (DCD) donors are frequently discarded for transplantation because of the high risk of graft failure. It is unknown whether DCD livers from older donors benefit from dynamic preservation.
Methods: In a multicenter study, we retrospectively compared graft and patient outcomes after transplantation of livers from DCD donors older than 60 y, preserved with either static cold storage (SCS), ex situ sequential dual hypothermic perfusion, controlled oxygenated rewarming, and normothermic perfusion (DHOPE-COR-NMP), or in situ abdominal normothermic regional perfusion (aNRP).
Subnormothermic Machine Perfusion of Neonatal and Small-Sized Pediatric Donor Hearts.

Donor heart machine perfusion enables avoidance of prolonged cold ischemia, however the optimal temperature is yet to be elucidated. Given that maintenance of temperature beyond ambient levels demands significant energy, we sought to determine the suitability of room-temperature perfusion preservation of neonatal/pediatric-sized (5-20 kg) piglet donor hearts. A custom device was fabricated suitable for this purpose, with continuous readout of perfusion pressure, flow rate, temperature, and oxygen saturation.
