Definition, Prognosis, and Complication Analysis of Early Allograft Dysfunction in Pediatric Liver Transplantation: A Retrospective Cohort Study.

Background: The definition of early allograft dysfunction (EAD) varies, and has hardly been studied in pediatric transplantation (pLT) since the adult EAD definition is not easily applicable to pLT.

Methods: A retrospective analysis was conducted on consecutive pLT patients aged <18 at the Department of Pediatric Transplantation of Tianjin First Central Hospital from April 2013 to December 2022. The definition of EAD explored in this study is (1) international normalized ratio ≥2.

Post-Liver Transplantation-Burkitt Lymphoma in Children: A Single-Center Study of Clinical Characteristics, Treatment, and Outcomes.

Background: Post-liver transplantation-Burkitt lymphoma (PLT-BL) is an aggressive and life-threatening complication after pediatric liver transplantation. The research on the disease characteristics, treatment, and prognosis of pediatric PLT-BL is limited.

Methods: A retrospective, observational study was performed to analyze the disease characteristics, treatment, and outcomes in 12 pediatric liver transplant (LT) recipients diagnosed with PLT-BL.

Liver transplantation for pediatric patients with congenital heart disease: A single-center study in mainland China.

Background: Liver transplantation (LT) is a serious cardiovascular stressor for patients with end-stage liver disease (ESLD). Data on the effects of cardiovascular diseases on pediatric LT is limited. No study on LT for pediatric patients with ESLD combined with congenital heart disease (CHD) has been reported from mainland China.

Impact of donor age on short-term outcomes after pediatric split liver transplantation.

Background: Donor shortage is an important limitation of liver transplantation (LT). Split liver transplantation (SLT) may increase the sources of donors and reduce the problem of organ shortage. However, there are no standard criteria of the selection of SLT donor, especially regarding the donor age.

Subclinical cardiac abnormalities in children with biliary atresia correlate with outcomes after liver transplantation.

Objective: There are subclinical cardiac abnormalities (SCA) in children with biliary atresia (BA). However, data on the consequences of these cardiac changes after liver transplantation (LT) remain controversial in the pediatric field. We aimed to determine the relationship between outcomes and the subclinical cardiac abnormalities in pediatric patients with BA based on two-dimensional echocardiography (2DE) parameters.

The value of F-FDG PET/CT quantitative indexes in the diagnosis of nondestructive posttransplant lymphoproliferative disorders after pediatric liver transplantation.

Background: Posttransplant lymphoproliferative disease (PTLD) is a serious complication after pediatric liver transplantation (pLT), which may lead to death. F-FDG PET/CT is rarely considered in PTLD after pLT and lacks clear diagnostic guidelines, especially in the differential diagnosis of nondestructive PTLD. The aim of this study was to find a quantifiable F-FDG PET/CT index to identify nondestructive PTLD after pLT.

Impact of different ischemia times on biliary stricture after living donor liver transplantation with biliary atresia.

Biliary atresia (BA) is the most common indication for pediatric liver transplantation, and biliary stricture (BS) remains an Achilles' heel for pediatric living donor liver transplantation (LDLT). We investigated the impact of different ischemia times on BS after LDLT in patients with BA. We retrospectively analyzed patients (<18 y) with BA who underwent LDLT between January 2016 and December 2020.

The impact of portal vein reconstruction on portal vein complications after pediatric living-donor liver transplantation with left lobe graft.

Background: This study aimed to determine whether the different methods of portal vein reconstruction have an impact on the occurrence of portal vein complications after pediatric living-donor liver transplantation with left lobe graft.

Methods: A total of 567 recipients were eligible for enrollment in this study and were divided into the following 2 groups according to the type of portal vein reconstruction: group 1 underwent anastomosis of the left and right bifurcations of the recipient portal vein to the donor portal vein (type 1), whereas group 2 underwent anastomosis of the bevel formed by the main trunk and right branch of the recipient portal vein to the donor portal vein (type 2). Postoperative portal vein complications and recipient and graft survival rates were compared between the 2 groups before and after propensity score matching.

Nomograms for Predicting the Incidence of Late-Onset Acute Cellular Rejection in Patients After Pediatric Liver Transplantation.

Background: Late-onset acute cellular rejection (LACR) is a special type of acute rejection (AR) only rarely studied after pediatric liver transplantation (pLT). Our study aimed to explore the influencing factors of LACR after pLT and establish a nomogram to provide an individualized prediction of LACR after pLT.

Materials And Methods: Data from 640 children who underwent pLT at Tianjin First Central Hospital from January 2016 to December 2019 were collected as part of this retrospective study.

A high environmental composite quality factor score was associated with the risk of sick building syndrome among adults in northeast China.

Objectives: Epidemiological evidence regarding the association between the combination of indoor and outdoor neighborhood pollution and sick building syndrome (SBS) among adults is limited and inconsistent. A cross-sectional study was conducted to investigate the association between the environmental composite quality factor score and SBS among adults.

Methods: This study included 2594 females and 666 males aged 18-77 years enrolled from the Northeast China.

Preparation and Dielectric Properties of SiC/LSR Nanocomposites for Insulation of High Voltage Direct Current Cable Accessories.

The conductivity mismatch in the composite insulation of high voltage direct current (HVDC) cable accessories causes electric field distribution distortion and even insulation breakdown. Therefore, a liquid silicone rubber (LSR) filled with SiC nanoparticles is prepared for the insulation of cable accessories. The micro-morphology of the SiC/LSR nanocomposites is observed by scanning electron microscopy, and their trap parameters are characterized using thermal stimulated current (TSC) tests.
