Racial and Ethnic Disparities in Survival Among Patients with Cholangiocarcinoma in the United States: A Systematic Review and Meta-Analysis.

Background: Cholangiocarcinoma (CCA) is an increasing cause of mortality in the U.S.; however, the burden of CCA disproportionately impacts racial and ethnic minority groups.

The path to liver transplantation for low MELD patients: A comparative analysis of deceased and living donor grafts in the perfusion technology era.

Patients with low MELD scores remain at substantial risk for waitlist removal. We investigated modern outcomes and graft utilization for low MELD patients undergoing liver transplant (LT) in the US. Adult LT recipients with low MELD scores (match MELD≤20) from 2022 to 2023 were identified from the UNOS database and stratified by receipt of a donation-after-circulatory-death (DCD), donation-after-brain-death (DBD), or living donor (LD) graft.

Prolonged allograft survival in liver transplantation.

Introduction: Donor age has traditionally been considered a factor associated with allograft failure in liver transplantation. We sought to examine the characteristics and outcomes of all liver allografts with a cumulative age of over 80 years within the US to better understand liver senescence.

Methods: Using the UNOS STARfile, allografts with a cumulative age (sum of age at transplant plus post-transplant survival) of octogenarian, 90-99 nonagenarian, and 100 years or greater (centurion) were identified from all adult transplant recipients between 1990 and 2022.

[Endovascular aortic repair in a patient with secondary aortoenteric fistula and critical lower limb ischemia].

The authors present successful treatment of a patient with aortoenteric fistula and chronic critical lower limb ischemia after previous aortobifemoral bypass grafting (ABF). Examination revealed intimate contact of inferior duodenal wall near proximal anastomosis and thrombosis of the right branch. The patient underwent hybrid surgery, i.

Reported transgenerational responses to in are not robust.

We report our attempt to replicate reports of transgenerational epigenetic inheritance in . Multiple laboratories report that adults and their F1 embryos exposed to the pathogen show pathogen aversion behavior and increased reporter gene expression. However, results from one group show persistence of both through the F4 generation.
