American Journal of Transplantation: Volume 15, Number 10, October 2015

On the cover this month : Paired exchange has emerged as an increasingly accepted means of fostering living donor kidney transplantation. As programs have expanded, practitioners are now moving beyond simple proof‐of‐concept implementation and on to process optimization. This month's AJT features three articles (Bray et al, page 2636 ; Fumo et al, page 2646 ; and Flechner et al, page 2712 ) germane to the incremental improvement of paired exchange processes, particularly those dealing with imperfections and progression failure inherent in processes dependent on complex human interactions. Gentry and Segev provide commentary on page 2539 . Cover image by Ken North, North Design Group .
