OBJECTIVE The aim of this study was to emphasize the significance of internal audits of the blood donor selection process and documentation in a resource-limited country by assessing compliance with the established protocols, and to identify weak areas in the process. MATERIALS AND METHODS This audit reviewed the donor selection process at the blood bank of Liaquat National Hospital & Medical...
This paper reports on and discusses the findings of an online survey initiated by the Donor Sibling Registry of 108 parents of children conceived following oocyte donation. Respondents generally supported early disclosure of donor conception to the child, although some bias in favour of disclosure cannot be excluded, given the recruitment source. Even so, extensive uncertainty regarding the opt...
Background: Oocyte donation and assisted reproductive technology (ART) give women with ovarian failure, advanced reproductive age, inheritable disorders or recurrent implantation failure, the ability to conceive. The success of oocyte donation is reportedly influenced by multiple parameters of the oocyte donor and recipient. The objective of this study was to evaluate the donor and recipient va...
BACKGROUND Policy decisions about opt-in and opt-out consent for organ donation are based on limited evidence. To fill this gap we investigated the difference between deceased and living organ donation rates in opt-in and opt-out consent systems across a 13 year period. We controlled for extensive covariates and estimated the causal effect of consent with instrumental variables analysis. METH...
Donor–donor?–acceptor molecules where the donor? bridges donor and acceptor have different possible interaction pathways for charge transfer.
BACKGROUND There is no reliable serum marker available to monitor incipient pancreas or islet-cell rejection. We tested the hypothesis that quantification of donor-specific genomic DNA in serum (from tissue damage) can serve as a marker of rejection. METHODS Using a recently developed panel of HLA-specific quantitative PCR assays (Q-PCR), we tested 158 sera from 42 pancreas-kidney transplant ...
Transplantation is an effective, life-prolonging treatment for organ failure. Demand has steadily increased over the past decade, creating a shortage in the supply of organs. In addition, the number of deceased organ donors has reached a plateau. Living-donor transplantation is increasingly an option, influenced by favourable clinical outcomes and increased waiting times at most transplant cent...

BACKGROUND A number of alternative donor options exist for patients who fail to find domestic HLA-matched donors for allogeneic hematopoietic stem cell transplantation (allo-HSCT). We assessed physicians' perspectives on allo-HSCT donor selection when a matched domestic donor is not available. METHODS We administered a questionnaire survey to 55 hematologists (response rate: 28%) who attended...
