Background: Transplantation is widely considered the gold standard method of kidney replacement therapy. Despite compelling evidence for biological sexual dimorphisms, the role of donor and recipient sex matching in transplantation is undefined.
Methods: The UK historical cohort study explores the impact of donor and recipient sex on allograft survival, in children receiving their first deceased donor transplant. Nationwide registry data were collected for 1316 transplant procedures performed from January 1, 1999, to December 31, 2019.
Results: Male donor-male recipient transplantation occurred most frequently (35%), followed by female donor-male recipient (23%), male donor-female recipient (22%), and female donor-female recipient (20%). The median follow-up time was 7.03 years (IQR: 2.89-12.4 years), with a total of 10,326 person-years. Male donor-male recipients were associated with the highest 10-year kidney allograft survival (72.8% [95% CI 68.3-77.8]) and male donor-female recipients with the lowest (64% [95% CI 57.7-71.1]). Multivariable Cox regression demonstrated for male donor transplantation, the risk of kidney allograft failure was 1.46 times greater for female (compared to male) recipients, after adjusting for acquired recipient age, recipient/donor age at transplantation, mismatched HLA A/B/DR, waitlist time, cold ischemia time, CMV seropositivity, donor hypertension, and donor diabetes (HR 1.46 [95% CI. 1.06-2.01], p = 0.02). There was no evidence for an independent effect of donor or recipient sex in other combinations.
Conclusion: This study highlights the complex relationship between donor and recipient sex and pediatric kidney allograft survival, which require further mechanistic evaluation.

Primary-lobe-based trilobed and quadrilobed flaps for reconstruction of nasal tip skin defects.
JPRAS Open
March 2025
Department of Plastic and Craniofacial Surgery, MITERA Hospital, Hellenic Healthcare Group (HHG), 6 Erithrou Stavrou str., 151 23 Maroussi, Attica, Greece.
Background: Despite a variety of principles proposed for drawing trilobed and quadrilobed flaps for the reconstruction of nasal skin defects, the application of these principles in a detailed and reliable way remains questionable.
Methods: We present a novel method for drawing trilobed and quadrilobed flaps to cover nasal tip skin defects. The method is based on the use of templates corresponding to four trilobed flaps with overall angles of 60°, 70°, 80°, and 90°, and two quadrilobed flaps with angles of 90° and 105°.
Human leukocyte antigen and donor-specific antibodies in liver transplantation.

In this article, we comment on an article published in a recent issue of the . We specifically focus on the roles of human leukocyte antigen (HLA) and donor-specific antibodies (DSAs) in pediatric liver transplantation (LT), as well as the relationship between immune rejection after LT and DSA. Currently, LT remains the standard of care for pediatric patients with end-stage liver disease or severe acute liver failure.

Introduction: Approximately 50% of patients with C3 glomerulopathy (C3G) and primary immune complex-mediated membranoproliferative glomerulonephritis (IC-MPGN) reach kidney failure 10 years after diagnosis. Because these patients are generally young, the majority will be listed for kidney transplantation (KTx). However, reported outcomes in patients transplanted for C3G and IC-MPGN are heterogeneous and conflicting, because they are mainly based on retrospective monocentric studies.

Marginal liver grafts, such as those from cardiac death donors and donors with steatotic organs, are highly vulnerable to ischemia-reperfusion injury. In addition, ex situ graft alteration, either by reduction or splitting, will prolong the static cold storage time and amplify the ischemia-reperfusion injury. Hypothermic oxygenated machine perfusion has the potential to end the oxygen deprivation during preservation and accordingly improve outcomes in some marginal grafts that have been traditionally discarded.

>From the Department of Pathology, Imam Reza Hospital, Mashhad University of Medical Sciences, Mashhad, Iran.
Objectives: Liver transplant is the most effective therapeutic option for patients with end-stage liver disease, nonalcoholic steatohepatitis, and acute liver failure. We evaluated whether the percentage of hepatic fat percentage affected transplant outcomes to determine whether livers with varying severity of macrosteatosis should be considered suitable for donation.
Materials And Methods: We analyzed data from 381 patients with liver failure who received liver transplant at Montaseriyeh Hospital in Mashhad, Iran, between 2013 and 2022.
