When rejection comes from within

A new cellular structure responsible for previously unexplained rejection of organ transplants has been identified. This discovery could one day revolutionize transplantation practice by modifying risk assessment of rejection in people who receive heart, lung, kidney, or liver transplants.

AbstractThe overall aim of this scoping review of the literature is twofold: (1) to provide an overview of all instruments that have been used to assess health-related quality of life (HRQoL) after solid organ transplantation and (2) to provide a list of health items they include to support future studies on the development of a new-generation HRQoL instrument. All studies that administered any form of HRQoL instrument to post-transplant solid organ recipients were identified in a comprehensive search of PubMed (MEDLINE), Embase, and Web of Science, with a cut-off date of May 2018. The search used various combinations of t...

Authors: Salehi S, Tran K, Grayson WL Abstract In the past, a diagnosis of organ failure would essentially be a death sentence for patients. With improved techniques for organ procurement and surgical procedures, transplantations to treat organ failure have become standard medical practice. However, while the demand for organs has skyrocketed, the donor pool has not kept pace leading to long recipient waiting lists. Organ preservation provides a means to increase the number of available transplantable organs. However, there are significant drawbacks associated with cold storage, the current gold standard. To addres...

Conclusion: This study demonstrates that organ transplant recipients, and especially children, are at increased risk of postoperative complications after cochlear implantation in comparison with healthy CI recipients.

A history of melanoma within the preceding 5 years is commonly considered a contraindication to solid organ transplantation. We investigated how a pretransplant history of melanoma impacts patient survival and melanoma recurrence. Institutional Review Board approval was obtained, and Duke’s retrospective database was used to identify 4552 patients who underwent a solid organ transplant at Duke University from 1 January 2001 to 31 December 2016. Data with regard to the transplant, melanoma characteristics, rejection episodes, and survival were recorded. Of 4552 patients who underwent a solid organ transplant, 12 (0.3%...

Conclusion Employment status pre-transplant being highly associated with employment status post-transplant, the process promoting return to work should be started well before surgery. Biomedical, psychological and social factors must be taken into account to promote return to work in transplanted patients.

However, due to the mismatch in demand and supply of the organ donors and recipients, organ donation after circulatory death has increased recently all over the world. Kidneys, liver and lungs are being used for transplantation from Donors after circulatory death (DCDDs). Recently, he...

Abstract Despite decades of formidable exploration, multi-organ ischemia-reperfusion injury (IRI) encountered, particularly amongst elderly patients with clinical scenarios, such as age-related arteriosclerotic vascular disease, heart surgery and organ transplantation, is still an unsettled conundrum that besets clinicians. Remote ischemic conditioning (RIC), delivered via transient, repetitive noninvasive IR interventions to distant organs or tissues, is regarded as an innovative approach against IRI. Based on the available evidence, RIC holds the potential of affording protection to multiple organs or tissues, w...

We report that the disruption of excitation-contraction coupling contributes to impaired force generation in the mouse model of Sod1 deficiency. Briefly, we found a significant reduction in sarcoplasmic reticulum Ca2+ ATPase (SERCA) activity as well as reduced expression of proteins involved in calcium release and force generation. Another potential factor involved in EC uncoupling in Sod1-/- mice is oxidative damage to proteins involved in the contractile response. In summary, this study provides strong support for the coupling between increased oxidative stress and disruption of cellular excitation contraction mac...

Abstract BACKGROUND Donor hypernatremia has been associated with reduced graft and recipient survival after heart, liver, kidney, and pancreas transplantation. However, it is unknown what effect donor hypernatremia has on graft and recipient outcomes after lung transplantation. The aim of this study was to investigate the relation of donor hypernatremia with the duration of postoperative mechanical ventilation, the incidence of severe primary graft dysfunction, and survival following lung transplantation. MATERIAL AND METHODS We analyzed all consecutive lung transplantations performed in adult patients at our cent...
