Background: Although there is a worldwide need to expand the donor pool, many cadaveric marginal livers are usually discarded for transplantation. Herein, we report the outcome of a series of patients receiving marginal grafts.
Methods: We analyzed all patients who underwent liver transplantation in our unit from August 2006 to March 2011 (n = 125) with the use of a prospectively collected database. Patients with ≥3 of donor (prolonged hypotensive episodes, donor age >55 years, high vasopressor drug requirement, hypernatremia, prolonged intensive care unit stay, elevated transaminases) and graft-related (cold ischemia >12 hours, warm ischemia time >40 minutes and steatosis >30%) extended criteria were defined as extremely marginal liver grafts (EMLG). The outcomes of patients receiving EMLG were compared with the recipients of grafts without any marginal criteria (ideal grafts).
Results: The EMLG group (n = 36) showed higher operative transfusion requirement (66.6% vs 55.6%) as well as 30-day (11.1% vs 55%) and 1-year (22.2% vs 5.5%) mortality rates, compared with the ideal grafts group (n = 18) but without a significant difference. Other variables, such as major complications, postoperative hemodialysis, ICU and hospital stay, and 1-year survival also were not significantly different.
Conclusions: The liver pool can be safely expanded using EMLG from deceased donors for liver transplantation. These usually discarded liver grafts showed similar early and long-term outcomes compared with ideal organs.

Finding Value in Pediatric Liver Transplantation: When Does Volume Matter?

Department of Pediatric Surgery, Phoenix Children's Hospital, Phoenix, Arizona. Electronic address:
Introduction: Pediatric liver transplantation provides substantial survival benefit. An emphasis on value-based practices has become a central theme in many surgical fields, but have not been well-studied in pediatric transplantation. Given an increasing focus on optimizing outcomes while containing costs, defining value in pediatric liver transplantation warrants investigation.

Objectives: A significant proportion of patients undergoing surgery for pancreatic ductal adenocarcinoma (PDAC) are anemic at the time of resection. In these patients, blood transfusions are omitted due to their potential negative impact on oncological outcomes. The aim of the present study was to determine the prognostic value of preoperative anemia in resected PDAC patients, irrespective of blood transfusion status.

Background: Patients with end-stage kidney disease often prefer home-based dialysis due to higher self-efficacy, which relates to improved medical treatment adherence. Kidney transplantation (KT) success depends on adhering to immunosuppressive medication post-transplant.
Objectives: To investigate whether adherence post-kidney transplantation (KT) and patients' attitudes toward immunosuppression were influenced by their prior dialysis type modality.
Activation of S1PR2 on macrophages and the hepatocyte S1PR2/RhoA/ROCK1/MLC2 pathway in vanishing bile duct syndrome.

Immunologic bile duct destruction is a pathogenic condition associated with vanishing bile duct syndrome (VBDS) after liver transplantation and hematopoietic stem-cell transplantation. As the bile acid receptor sphingosine 1-phosphate receptor 2 (S1PR2) plays a critical role in recruitment of bone marrow-derived monocytes/macrophages to sites of cholestatic liver injury, S1PR2 expression was examined using cultured macrophages and patient tissues. Bile canaliculi destruction precedes intrahepatic ductopenia; therefore, we focused on hepatocyte S1PR2 and the downstream RhoA/Rho kinase 1 (ROCK1) signaling pathway and bile canaliculi alterations using three-dimensional hepatocyte culture models that form obvious bile canaliculus-like networks.

Liver ischemia-reperfusion (IR) injury is a common complication following liver surgery, significantly impacting the prognosis of liver transplantation and other liver surgeries. Betaine-homocysteine methyltransferase (BHMT), a crucial enzyme in the methionine cycle, has been previously confirmed the pivotal role in hepatocellular carcinoma, and it has also been demonstrated that BHMT inhibits inflammation, apoptosis, but its role in liver IR injury remains unknow. Following I/R injury, we found that BHMT expression was significantly upregulated in human liver transplant specimens, mice and hepatocytes.
