Purpose of review: Living donor transplantation offers patients with end-stage renal disease faster access to transplant and better survival and quality of life than waiting for a deceased donor or remaining on dialysis. While many people state they would be willing to help someone in need through kidney donation, there are education and communication barriers to donor candidate identification. These barriers might be mitigated by technological innovations, including the use of social media...

REVIEW
Robert L Gottlieb, Shelley A Hall
Purpose of Review: The landscape of abdominal organ transplantation has been altered by the emergence of curative direct-acting antiviral agents for hepatitis C. Expansion of the thoracic donor pool to include the hearts and the lungs from hepatitis C-positive donors holds promise to increase available donor organs. Recent Findings: Case reports have documented separate lung and heart transplant patients who acquired, and then were cured of, donor-derived hepatitis C using these newer, more effective therapies...

REVIEW
Christopher J E Watson, Ina Jochmans
Purpose of Review: The purpose of this review was to summarise how machine perfusion could contribute to viability assessment of donor livers. Recent Findings: In both hypothermic and normothermic machine perfusion, perfusate transaminase measurement has allowed pretransplant assessment of hepatocellular damage. Hypothermic perfusion permits transplantation of marginal grafts but as yet has not permitted formal viability assessment. Livers undergoing normothermic perfusion have been investigated using parameters similar to those used to evaluate the liver in vivo...

Purpose of Review: The goal of this paper is to highlight the major challenges in the translation of human pluripotent stem cells into a clinical setting. Recent Findings: Innate features from human induced pluripotent stem cells (hiPSCs) positioned these patient-specific cells as an unprecedented cell source for regenerative medicine applications. Immunogenicity of differentiated iPSCs requires more research towards the definition of common criteria for the evaluation of innate and host immune responses as well as in the generation of standardized protocols for iPSC generation and differentiation...

REVIEW
Clifford D Miles, Scott Westphal, AnnMarie Liapakis, Richard Formica
Purpose: The number of simultaneous liver-kidney transplants (SLKT) performed in the USA has been rising. The Organ Procurement and Transplantation Network implemented a new policy governing SLKT that specifies eligibility criteria for candidates to receive a kidney with a liver, and creates a kidney waitlist "safety net" for liver recipients with persistent renal failure after transplant. This review explores potential impacts for liver patients and the kidney waitlist. Recent Findings: Factors that have contributed to the rise in SLKT including Model for End-stage Liver Disease (MELD)-based allocation, regional sharing for high MELD candidates, and the rising incidence of non-alcoholic steatohepatitis will continue to increase the number of liver transplant candidates with concurrent renal insufficiency...

PURPOSE OF REVIEW: For the more than 636,000 adults with end-stage renal disease (ESRD) in the U.S., kidney transplantation is the preferred treatment compared to dialysis. Living donor kidney transplantation (LDKT) comprised 31% of kidney transplantations in 2015, an 8% decrease since 2004. We aimed to summarize the current literature on decision aids that could be used to improve LDKT rates. RECENT FINDINGS: Decision aids are evidence-based tools designed to help patients and their families make difficult treatment decisions...
