An 82-year-old recipient of split liver transplantation worldwide: A case report.

Split liver transplantation (SLT) has become an indispensable method for expanding the donor liver pool. However, advanced age in recipients can have significant adverse effects on prognosis. We report the case of an 82-year-old man with chronic liver failure and polycystic liver disease who underwent split right triple lobe donor liver transplantation on October 29, 2021.

Causal associations between changes in lipid profiles and risk of gallstone disease: a two-sample Mendelian randomization study.

Background: Nonalcoholic fatty liver disease (NAFLD) has been linked to gallstone disease (GSD) in observational studies; however, the relationships between certain lipid profiles and GSD remain unclear.

Methods: We adopted a two-sample Mendelian randomization (MR) framework by applying different statistical methods to assess causalities between lipid profiles and GSD. We identified single-nucleotide polymorphisms (SNPs) for blood lipids and NAFLD from separate previous genome-wide association studies (GWASs).

Extracellular vesicles derived from mesenchymal stromal cells as nanotherapeutics for liver ischaemia-reperfusion injury by transferring mitochondria to modulate the formation of neutrophil extracellular traps.

As nanotherapeutics, mesenchymal stromal cell-derived extracellular vesicles (MSC-EVs) are considered a potent alternative for whole-cell therapy and are gradually entering the clinical field of liver diseases. In this study, neutrophil extracellular traps (NETs) formation in liver tissue was verified as a critical factor for liver ischaemia-reperfusion injury (IRI) in both clinical samples and animal models. Human umbilical cord-derived MSC-EVs (hUC-MSC-EVs) might function to reduce the NETs formation and subsequently improve liver IRI.

Norcholic Acid Promotes Tumor Progression and Immune Escape by Regulating Farnesoid X Receptor in Hepatocellular Carcinoma.

Accumulating evidence shows a close association between various types of bile acids (BAs) and hepatocellular carcinoma (HCC), and they have been revealed to affect tumor immune response and progression mainly by regulating Farnesoid X receptor (FXR). Nevertheless, the roles of Norcholic acid(NorCA) in HCC progression remain unknown yet. In this study, herein we demonstrate that NorCA can promote HCC cell proliferation, migration and invasion through negatively regulating FXR.

Upregulation of SKA3 enhances cell proliferation and correlates with poor prognosis in hepatocellular carcinoma.

Hepatocellular carcinoma (HCC) is one of the most aggressive types of malignancy worldwide. However, the mechanism underlying its frequent recurrence remains unclear. Studies have demonstrated that spindle and kinetochore associated complex subunit 3 (SKA3) is highly expressed in colorectal and prostate cancer.

Preoperative identification of microvascular invasion in hepatocellular carcinoma by XGBoost and deep learning.

Purpose: Microvascular invasion (MVI) is a valuable predictor of survival in hepatocellular carcinoma (HCC) patients. This study developed predictive models using eXtreme Gradient Boosting (XGBoost) and deep learning based on CT images to predict MVI preoperatively.

Methods: In total, 405 patients were included.

Feasibility of laparoscopic isolated caudate lobe resection for rare hepatic mesenchymal neoplasms.

Background: Mesenchymal tumors such as perivascular epithelioid cell neoplasm (PEComa) and inflammatory pseudotumor-like follicular dendritic cell sarcoma (IPT-like FDC sarcoma) are relatively uncommon in the liver and are particularly rare in the caudate lobe. The clinical manifestations and available imaging tests lack specificity for hepatic mesenchymal tumors. To the best of our knowledge, no caudate PEComa or IPT-like FDC sarcoma has been completely resected by laparoscopy.

Predictive Value of Age-Bilirubin-International Normalized Ratio-Creatinine Score in Short-Term Survival of Acute-on-Chronic Hepatitis B Liver Failure.

Background/aims: The age-bilirubin-international normalized ratio-creatinine (ABIC) score, which is a predictive model commonly used for alcoholic hepatitis, has not yet been studied in acute-on-chronic hepatitis B liver failure (HBV-ACLF). We aimed to investigate the predictive value of the ABIC score in patients with HBV-ACLF.

Methods: This retrospective study involved 398 patients diagnosed with HBV-ACLF, who were divided into a training cohort of 305 patients and a validation cohort of 93 patients.

Extracellular vesicles derived from human umbilical cord mesenchymal stem cells alleviate rat hepatic ischemia-reperfusion injury by suppressing oxidative stress and neutrophil inflammatory response.

Mesenchymal stem cells (MSCs) have been reported to exert therapeutic effects on immunoregulation, tissue repair, and regeneration from the bench to the bedside. Increasing evidence demonstrates that extracellular vesicles (EVs) derived from MSCs could contribute to these effects and are considered as a potential replacement for stem cell-based therapies. However, the efficacy and underlying mechanisms of EV-based treatment in hepatic ischemia-reperfusion injury (IRI) remain unclear.

Preoperative Alfa-Fetoprotein and Fibrinogen Predict Hepatocellular Carcinoma Recurrence After Liver Transplantation Regardless of the Milan Criteria: Model Development with External Validation.

Background/aims: Patient selection is critically important in improving the outcomes of liver transplantation for hepatocellular carcinoma. The aim of the current study was to identify biochemical measures that could affect patient prognosis after liver transplantation.

Methods: A total of 119 patients receiving liver transplantation for hepatocellular carcinoma were used to construct a model for predicting recurrence.

Systemic Immune-Inflammation Index (SII) is Useful to Predict Survival Outcomes in Patients After Liver Transplantation for Hepatocellular Carcinoma within Hangzhou Criteria.

Background: There is growing evidence that the systemic immune-inflammation index (SII), a novel prognostic biomarker based on peripheral lymphocyte, neutrophil, and platelet counts, is associated with poor prognosis for several tumors. However, the prognostic value of SII in patients with hepatocellular carcinoma (HCC) who undergo liver transplantation (LT) remains unclear. The aim of this study was to determine the correlation between SII and prognosis in these patients.

Cancer-associated fibroblasts induce PDL1+ neutrophils through the IL6-STAT3 pathway that foster immune suppression in hepatocellular carcinoma.

Emerging evidence indicate that cancer-associated fibroblasts (CAFs) affect tumor progression by reshaping the tumor microenvironment. Neutrophils are prominent components of solid tumors and important in cancer progression. Whether the phenotype and function of neutrophils in hepatocellular carcinoma (HCC) are influenced by CAFs is not well understood.

Neutrophil to Lymphocyte Ratio and Platelet to Lymphocyte Ratio as Prognostic Predictors for Hepatocellular Carcinoma Patients with Various Treatments: a Meta-Analysis and Systematic Review.

Background/aims: Systemic inflammatory response (SIR) is widely considered as a preoperative risk factor for hepatocellular carcinoma (HCC) outcomes. The neutrophil to lymphocyte ratio (NLR) and platelet to lymphocyte ratio (PLR), two of the prognostic indices, have been investigated in post-therapeutic recurrence and survival of HCC. Here, we quantify the prognostic value of these two biomarkers and evaluate their consistency in different HCC therapies.
