American Journal of Transplantation: Volume 15, Number 3, March 2015

  • First Published: 18 February 2015

On the cover this month: Transplantation has always been viewed as a multispecialty discipline, dependent on the aggregate actions of many diverse professionals. As healthcare reform moves us to more explicitly value the actions involved in care delivery, transplant clinicians will need to determine how best to establish compensation methods that recognize the complexity of the profession. This month, Abouljoud et al (page 601) present a novel model for establishing value for the purpose of setting compensation. Also see the editorial comment by Abecassis and Pearson (page 579) and a related brief communication on transplant surgeon burnout by Jesse et al (page 772).

The AJT Report

  • Pages: 575-576
  • First Published: 18 February 2015

Despite movement in the United States toward cost-saving bundled payments to physicians, the Centers for Medicare and Medicaid Services issued a final rule for the 2 015 Medicare Physician Fee Schedule that unbundles 10- and 90-day global payments, and that allows only zero-day payment for surgical services. This month, “The AJT Report” talks to transplant surgeons about what the new paymen t provisions mean for their practices. Also in this issue, we take a look at China's recent announcement that it has ceased the use of organs from executed prisoners effective this year, a policy met with both support and skepticism from the transplant community.

  • Pages: 581-582
  • First Published: 18 February 2015

Although the initial experience with Share 35 liver allocation has enhanced regional sharing for sick liver transplant candidates while increasing organ utilization and national transplant volume, potential costs with regard to system efficiency and the impact on mid- to long-term posttransplant outcomes remain to be delineated.

Blockade of CD40–CD154 Costimulatory Pathway Promotes Long-Term Survival of Full-Thickness Porcine Corneal Grafts in Nonhuman Primates: Clinically Applicable Xenocorneal Transplantation

  • Pages: 628-641
  • First Published: 12 February 2015

Using a pig-to-nonhuman primate full-thickness corneal transplant model, the authors show that programmed administration of antibodies to CD154 (CD40 ligand) significantly prolongs corneal xenograft survival; markedly reduces inflammatory cellular infiltrations into the graft; almost completely blocks xenoantigen-triggered increases in Th1-associated cytokines, chemokines, and C3a in the aqueous humor; and effectively controls systemic expansion of memory T cells and anti-Gal/donor pig-specific antibodies.
