Whereas the gap between organ supply and demand remains a worldwide concern, resuscitation of out-of-hospital traumatic cardiac arrest (TCA) remains controversial. The aim of this study is to evaluate, in a prehospital medical care system, the number of organs transplanted from victims of out-of-hospital TCA. This is a descriptive study. ⋯ Out-of-hospital TCA should be resuscitated just as medical CA. With a steady prevalence in our network, 19% of admitted TCA survived to discharge, and 11% became organ donors. It is essential to raise awareness among rescue teams that out-of-hospital TCA are an organ source to consider seriously.

Randomized Controlled Trial
One-year results of a prospective, randomized trial comparing two machine perfusion devices used for kidney preservation.
Studies have shown beneficial effects of machine perfusion (MP) on early kidney function and long-term graft survival. The aim of this study was to investigate whether the type of perfusion device could affect outcome of transplantation of deceased donor kidneys. A total of 50 kidneys retrieved from 25 donors were randomized to machine perfusion using a flow-driven (FD) device (RM3; Waters Medical Inc) or a pressure-driven (PD) device (LifePort; Organ Recovery Systems), 24 of these kidneys (n = 12 pairs; 48%) were procured from expanded criteria donors (ECD). ⋯ Interstitial fibrosis and tubular atrophy were significantly more common in the FD group - 45% (5/11) vs. 0% (0/9) (P = 0.03) in PD group. There were no differences in creatinine levels between the groups. Machine perfusion using a pressure-driven device generating lower pulse stress is superior to a flow-driven device with higher pulse stress for preserving kidney function.

Donation after cardiac death liver transplant recipients have an increased frequency of acute kidney injury (AKI). This suggests that hepatic ischemia-reperfusion injury may play a critical role in the pathogenesis of AKI after liver transplantation. The aim of this single-center study was to determine if hepatic ischemia-reperfusion injury, estimated by peak peri-operative serum amino-transferase (AST), is associated with AKI following donation after brain death (DBD) liver transplantation. ⋯ The incidence of AKI in patients with a peak AST of <1500, 1500-2999 and ≥ 3000 U/l was 26.1%, 39.8% and 71.2%, respectively (P < 0.001). On multiple logistic regression analysis, peak AST was independently associated with the development of AKI (P < 0.001). In conclusion, hepatic ischemia-reperfusion injury demonstrates a strong relationship with peri-operative AKI in DBD liver transplant recipients.

Macrophage activation syndrome (MAS) is a rare, potentially fatal condition, which most frequently complicates rheumatological conditions and is often associated with liver dysfunction. In this case report of a patient with MAS, acute liver failure developed despite conventional immunosuppressive therapy. ⋯ A recent diagnosis of Adult Onset Still's Disease (AOSD) provides additional supporting evidence that the initial presentation was caused by MAS. While transplantation in the context of systemic disease remains controversial, this first reported case of successful adult liver transplantation for acute liver failure caused by MAS raises an interesting clinical dilemma.

The growth in living kidney donation has been accompanied by greater racial diversity. Most information on post-donation health comes from single-center studies of dominantly Caucasian cohorts. Recent linkage of U. ⋯ Thus, based on concerns for higher risks of long-term end-organ damage, it may be reasonable to consider race within the living donor selection process, such as use of more stringent exclusion criteria among non-Caucasian living donors with baseline elevated blood pressure. Recently identified associations of coding variants in the apolipoprotein L1 (APOL1) gene with nondiabetic renal failure in African Americans raise promise of APOL1 genotyping as a novel tool for risk stratifying African American potential donors, but more data are needed to understand implications for post-donation outcomes. To tailor counseling and informed consent, focused attention to long-term medical outcomes among non-Caucasian living donors is needed, and should include assembly of healthy non-donor controls for assessment of attributable risks of donation.
