AI Article Synopsis
- The study examines heart transplant effectiveness in Italy, focusing on the impact of donor age on patient survival rates.
- Data from 2,504 adult heart transplant patients showed a 1-year graft survival rate of 83.1%, with lower survival rates for donors over 55.
- Findings indicate that the relationship between donor age and transplant success is complex, with a peak risk of graft failure at age 47.3 and variations based on the recipient's sex.
Article Abstract
Background: Only half of the patients waiting for a heart transplant undergo surgery, whereas several patients continue to die while on the waiting list. Donor organ availability still represents a major problem with respect to reducing the length of the cardiac transplant waiting list. One option to improve donor availability is the use of so called "marginal donors." The aims of the present study are to analyze the short-mid term survival of cardiac transplanted patients in Italy, and investigate the effect of donor age on prognosis.
Methods: A prospective cohort study including all adult patients who underwent heart transplantations in Italy was used to analyze the main factors contributing to organ survival.
Results: From 1995-2002, 2,504 adult subjects underwent a cardiac transplant, and were followed up for a period of 540.9 days. Overall, 1-year graft survival was 83.1%. Organs from donors older than 55 years had a lower survival than organs from younger donors. By multivariate analysis, both donor's and recipient's age seem to be important determinants of graft survival. A more sophisticated analysis shows that the trend of the risk of graft failure according to donor's age is not linear, with a peak at age 47.3 years, and differs according to sex.
Conclusions: Results from the present analysis suggest that the association between heart transplant survival and donor's age is not a linear one, but follows a complex mathematical model, with influences of sex, at least in our sample.

The Association of Epstein-Barr Virus Donor and Recipient Serostatus With Outcomes After Kidney Transplantation : A Retrospective Cohort Study.
Ann Intern Med
January 2025
Renal-Electrolyte Division, University of Pittsburgh Medical Center, Pittsburgh, Pennsylvania (M.C.-P., R.B.M., C.M.P.).
Background: Prior studies indicate that 1% to 4% of Epstein-Barr virus (EBV)-seronegative recipients of EBV-seropositive donor (EBV D+/R-) kidneys develop posttransplant lymphoproliferative disorder (PTLD). However, these estimates are based on limited data that lack granularity.
Objective: To determine the associations between pretransplant EBV D+/R- and recipient EBV-seropositive status (R+) and the outcomes of PTLD and graft and patient survival among adult kidney transplant recipients.
Outcomes of Liver Transplant for Hepatic Epithelioid Hemangioendothelioma.

Division of Transplantation Surgery, Department of Surgery, Johns Hopkins Hospital, Baltimore, Maryland, USA.
Introduction: Hepatic epithelioid hemangioendothelioma (HEH) is a rare indication of liver transplant with limited evidence.
Methods: Adult recipients undergoing first-time liver-only transplant from 2002 to 2021 in the United States were identified using the UNOS/OPTN database. We compared post-transplant outcomes of recipients receiving liver transplant for HEH versus other diagnoses.
Role of Locoregional Therapy on Survival After Living Donor Liver Transplantation for Hepatocellular Carcinoma--Experience from a High-volume Center.

Background: Locoregional therapy (LRT) in patients with hepatocellular carcinoma (HCC) before liver transplantation (LT) has a role in improving the tumor biology and post-LT survival outcome apart from downstaging and bridging. We retrospectively analyzed our database of adult living donor liver transplants (LDLT) for HCC, to compare the survival outcomes in Group-1 (upfront-LT, HCC within Milan/UCSF/AFP<1000 ng/ml) and Group-2 (LT post-LRT, HCC beyond UCSF/irrespective of tumor burden with AFP>1000 ng/ml). We also explored the risk factors for recurrence on follow-up.

Background: Currently, there are no standardized guidelines for graft allocation in heart transplants (HTxs), particularly when considering organs from marginal donors and donors after cardiocirculatory arrest. This complexity highlights the need for an effective risk analysis tool for primary graft dysfunction (PGD), a severe complication in HTx. Existing score systems for predicting PGD lack superior predictive capability and are often too complex for routine clinical use.

Aim: This retrospective study explored the association between donor and recipient sex on hospital-onset sepsis (HO-sepsis) and Hb changes in critically ill patients receiving red blood cell (RBC) transfusions.
Methods: Data from 2010-2020 were extracted from an academic hospital's clinical database and a blood supplier's donor database.
