The MUC5B Promoter Polymorphism is Not Associated With Non-ILD Chronic Respiratory Diseases or Post-transplant Outcome.

Transpl Int 2022 16;35:10159. Epub 2022 May 16.

BREATHE, Department of Chronic Diseases and Metabolism, KU Leuven, Leuven, Belgium.

The MUC5B promoter polymorphism (rs35705950) has been associated with interstitial lung disease (ILD) and with prolonged pre-transplant survival in idiopathic pulmonary fibrosis (IPF), but no information is available regarding its prevalence in other respiratory diseases and its influence on post-transplant outcome. We included the Leuven lung transplantation cohort between 1991 and 2015 ( = 801). We assessed the minor allele frequency (MAF) of the MUC5B variant in the entire study cohort and investigated the influence of recipient MUC5B promoter polymorphism on post-transplant outcome in patients who were transplanted after 2004.

Centralized Organ Recovery and Reconditioning Centers.

Thorac Surg Clin 2022 May;32(2):167-174

Department of Surgery, Washington University School of Medicine, Campus Box 8234, 660 South Euclid Avenue, St Louis, MO 63110, USA; Department of Pathology & Immunology, Washington University School of Medicine, Campus Box 8234, 660 South Euclid Avenue, St Louis, MO 63110, USA.

An increased focus on improving efficiency and decreasing costs has resulted in alternative models of donor management and organ recovery. The specialized donor care facility model provides highly efficient and cost-effective donor care at a free-standing facility, resulting in improved organ yield, shorter ischemic times, decreased travel, and fewer nighttime operations. Ex vivo lung perfusion (EVLP) improves utilization of extended criteria donor lungs, and centralized EVLP facilities have the potential to increase transplant volumes for smaller transplant programs in specified geographic regions.
