Finding Value in Pediatric Liver Transplantation: When Does Volume Matter?
J Surg Res
January 2025
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.

Pancreas
January 2025
Department of Surgery, Division of Hepato-Pancreato-Biliary Surgery and Liver Transplantation, University Medical Center Groningen, University of Groningen, the Netherlands.
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.

Helsinki University Hospital, Abdominal Centre, Transplantation and Liver Surgery, and University of Helsinki, Helsinki, Finland.
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.
PLoS One

Department of Surgical Pathology, Kyoto Prefectural University of Medicine, Kyoto, Japan.
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.

Department of Hepatobiliary and Pancreatic Surgery, The First Affiliated Hospital of Zhengzhou University, Zhengzhou, China.
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.
