Background: Shortage of size-matched pediatric donors led to the development of surgical techniques to reduce or split livers and thus increase the potential pool of donors. Despite this, neonatal transplantation remains a problem because of the small size of the recipients. Further reduction of the left lateral segment is possible to provide a single segment graft (segment III). We report our experience of transplanting 6 babies using this technique.
Methods: Of 310 children transplanted in our center between October 1989 and March 1998, 6 patients, 2 male and 4 female, median age 37.5 days (range 5 to 92 days), median weight 3.45 kg (range 2.45 to 5.46 kg) were transplanted with a monosegment. The cause of liver failure was neonatal hemochromatosis in 4, retransplantation for hepatic artery thrombosis in 1, and hepatitis B in one. The donor liver was reduced or split to a left lateral segment. Segment II was then resected and discarded before transplantation.
Results: Overall, graft and patient survival is 83.3%. Five patients are alive with good graft function at a mean follow-up of 30.4 months (range 8 to 82 months). One child who was transplanted for hepatic artery thrombosis died from sepsis and multiorgan failure 48 hrs after transplant. None of the survivors had vascular or biliary complications.
Conclusions: Monosegment liver transplantation with segment III appears to be a satisfactory option for treating small babies with liver failure.

Background: Patients undergoing liver transplantation (LT) are at risk of perioperative neurocognitive dysfunction (PND), which significantly affects the patients' prognosis.
Objective: This study used machine learning (ML) algorithms with an aim to extract critical predictors and develop an ML model to predict PND among LT recipients.
Methods: In this retrospective study, data from 958 patients who underwent LT between January 2015 and January 2020 were extracted from the Third Affiliated Hospital of Sun Yat-sen University.

Although living donor liver transplantation has evolved, small-for-size syndrome remains a feared complication. Achieving optimal outflow for the graft with limited donor risk is possible with an experienced team and different techniques. Here we describe the technical aspects of living donor liver transplantation using a right lobe graft, including the different types of grafts, venous reconstructions and the importance of preoperative workup.

Objective: Donor liver preservation methods and solutions have evolved over the last years. Liver sinusoidal endothelial cell (LSEC) barrier function and integrity during preservation is crucial for outcomes of liver transplantation. Therefore, the present study aimed to determine optimal preservation of LSEC barrier function and integrity, using different preservation solutions.

The gut-brain axis is a bidirectional communication pathway that modulates cognitive function. A dysfunctional gut-brain axis has been associated with cognitive impairments during aging. Therefore, we propose evaluating whether modulation of the gut microbiota through fecal microbiota transplantation (FMT) from young-trained donors (YT) to middle-aged or aged mice could enhance brain function and cognition in old age.

Appetite, as the internal drive for food intake, is often dysregulated in a broad spectrum of conditions associated with over- and under-nutrition across the lifespan. Appetite regulation is a complex, integrative process comprising psychological and behavioral events, peripheral and metabolic inputs, and central neurotransmitter and metabolic interactions. The microbiota-gut-brain axis has emerged as a critical mediator of multiple physiological processes, including energy metabolism, brain function, and behavior.
