Objective: To study the effects of cluster of differentiation 40 ligand immunoglobulin (CD40LIg) gene-modified bone marrow mesenchymal stem cells (MSCs) on liver graft rejection in rats.
Methods: The orthotopic liver transplantation models were established with DA rats as the donors and Lewis rats as the recipient. MSCs infected with the recombinant adenoviruses containing CD40LIg gene were infused into the liver graft after transplantation. The liver function, survival of the recipient rats and the morphological changes of the liver grafts were observed after the transplantation. The serum levels of the cytokines interferon-γ (INF-γ) and interleukin-2 (IL-2) in the recipient rats were quantified by ELISA.
Results: The survival of the recipient rats receiving transplantation of genetically modified MSCs (group D) was significantly prolonged compared with that of the control group (group A), MSCs group (group B) and gene transfection group (group C); the survival of groups B and C were significantly longer than that of group A (F=7.615, P<0.05). The level of serum alanine aminotransferase, total bilirubin, IL-2 and INF-γ were significantly higher in group A than in the other 3 groups (F=8.738, P<0.05). HE staining of the liver grafts showed severe acute rejection in group A, mild acute graft rejection in groups B and group C, but no rejection in group D.
Conclusion: CD40LIg gene-modified MSCs can prolong the survival of the recipient rats and suppress graft rejection following liver transplantation.

Adjuvant Chemotherapy After Resection of Localized Pancreatic Adenocarcinoma Following Preoperative FOLFIRINOX.
JAMA Oncol
January 2025
Amsterdam UMC, location University of Amsterdam, Department of Surgery, Amsterdam, the Netherlands.
Importance: The effect of adjuvant chemotherapy following resection of pancreatic adenocarcinoma after preoperative (m)FOLFIRINOX (combination leucovorin calcium [folinic acid], fluorouracil, irinotecan hydrochloride, and oxaliplatin in full or modified dosing) chemotherapy on overall survival (OS) is unclear because current studies do not account for the number of cycles of preoperative chemotherapy and adjuvant chemotherapy regimen.
Objective: To investigate the association of adjuvant chemotherapy following resection of pancreatic adenocarcinoma after preoperative (m)FOLFIRINOX with OS, taking into account the number of cycles of preoperative chemotherapy and adjuvant chemotherapy regimen.
Design, Setting, And Participants: This retrospective cohort study included patients with localized pancreatic adenocarcinoma treated with 2 to 11 cycles of preoperative (m)FOLFIRINOX followed by resection across 48 centers in 20 countries from 2010 to 2018.

Department of Infectious Diseases, Hospices Civils de Lyon, Service des Maladies Infectieuses et Tropicales, 103 Grande Rue de la Croix-Rousse, Lyon, 69004, France.
Purpose: Abdominal wall reconstruction is a common surgical procedure, with a post-operative risk of mesh-associated infection of which management is poorly known. This study aims to comprehensively analyze clinical and microbiological aspects of mesh infection, treatment modalities, and associated outcomes.
Methods: Patients with abdominal mesh infection were included in a retrospective observational cohort (2010-2023).
Transesophageal echocardiography monitoring for liver transplantation: where are we now?

Intraoperative hemodynamic monitoring is crucial for managing patients with end-stage liver disease (ESLD) undergoing orthotopic liver transplantation (OLT) due to their complex cardiovascular and pulmonary abnormalities. Traditionally, pulmonary artery catheterization (PAC) has been the standard for hemodynamic monitoring during OLT. However, the use of transesophageal echocardiography (TEE) has increased due to its real-time visualization of cardiac and vascular structures, which aids in managing hemodynamic instability during the three surgical phases of OLT: pre-anhepatic, anhepatic, and neo-hepatic.

Background & Aims: Venous thromboembolism (VTE) is a recognized complication of acutely ill patients, but its incidence and risk factors in those with cirrhosis are uncertain.
Methods: We retrospectively studied a consecutive cohort of cirrhosis patients non-electively admitted to our medical unit to determine the rates of symptomatic VTE during hospitalization. Firstly, we explored associations with baseline, clinical and laboratory characteristics using logistic regression.

Hepatocellular carcinoma (HCC) and biliary tract cancers (BTC) pose significant diagnostic and therapeutic challenges. Magnetic resonance imaging (MRI) and multiphase computed tomography (CT) have been the preferred imaging modalities for diagnosis, staging, and surveillance of patients with these malignancies. The best clinical outcomes depend on the appropriate selection of treatment options from the tools available in neo-adjuvant therapy, surgical resection, locoregional therapy, liver transplantation, and adjuvant therapy.
