PURPOSE OF REVIEW: The 'Final Rule,' issued by the Health Resources and Service Administration in 2000, mandated that liver allocation policy should be based on disease severity and probability of death, and - among other factors - should be independent of a candidate's residence or listing. As a result, the Organ Procurement Transplantation Network/United Network for Organ Sharing (UNOS) has explored policy changes addressing geographic disparities without compromising outcomes. RECENT FINDINGS: Major paradigm shifts are underway in U...

INTRODUCTION The N terminal prohormone of brain natriuretic peptide (NT proBNP) is secreted by cardiomyocytes in response to increased wall stress resulting from pressure and volume overload. The modified Model for End Stage Liver Disease (modMELD) scale reflects the systemic effect of heart failure (HF), which includes end-organ congestion and subsequent hepatic and renal dysfunction. OBJECTIVES The aim of this study was to assess the prognostic accuracy of NT proBNP and the modMELD score, as well as to compare their usefulness in the risk stratification of patients with end-stage HF awaiting orthotopic heart transplantation (OHT)...

Polycystic kidney disease (PKD) is a genetic disorder characterized by fluid-filled cysts in the kidney and liver that ultimately leads to end-stage renal disease. Currently there is no globally approved therapy for PKD. The Notch signaling pathway regulates cellular processes such as proliferation and de-differentiation, which are cellular hallmarks of PKD. Thus we hypothesized that the Notch pathway plays a critical role in PKD. Evaluation of protein expression of Notch signaling components in kidneys of Autosomal Recessive PKD (ARPKD) and Autosomal Dominant PKD (ADPKD) mouse models and of ADPKD patients revealed that Notch pathway members, particularly Notch3, were consistently upregulated or activated in cyst-lining epithelial cells...

BACKGROUND: Portal vein thrombosis (PVT) develops in cirrhotic patients because of stagnation of blood flow. Transjugular intrahepatic portosystemic shunt (TIPS) creates a low-resistance conduit that restores portal venous patency and blood flow. AIM: The effect of PVT on transplant-free survival in cirrhotic patients undergoing TIPS creation was evaluated. PATIENTS AND METHODS: A multicenter, retrospective cohort study of patients who underwent TIPS creation for cirrhotic portal hypertension was carried out...

Liver fibrosis is a disease that causes high morbidity and has become a major health problem. Liver fibrosis can lead to the end stage of liver diseases (livercirrhosisand hepatocellularcarcinoma). Currently, liver transplantation is the only effective treatment for end-stage liver disease. However, the shortage of organ donors, high cost of medical surgery, immunological rejection and transplantation complications severely hamper liver transplantation therapy. Mesenchymal stem cells (MSCs) have been regarded as promising cells for clinical applications in stem cell therapy in the treatment of liver diseases due to their unique multipotent differentiation capacity, immunoregulation and paracrine effects...

INTRODUCTION: Acute liver failure (ALF) is an indication for emergency liver transplantation (LT). Although centers performing only deceased donor liver transplants (DDLT) have shown improved outcomes in this situation, they still have relatively long waiting lists. An alternative would be living donor liver transplantation (LDLT), which has shown equivalent outcomes in the elective situation but there is limited evidence of its results in ALF. AIM: The purpose of this study was to assess the outcomes in patients with ALF undergoing emergency LDLT in our center in Delhi, India...

BACKGROUND: Semaphorin 7A (SEMA7A) is an immunomodulating protein implicated in lung and liver fibrosis. In autosomal-dominant polycystic kidney disease (ADPKD), the progressive expansion of renal cysts, inflammation, and subsequent renal fibrosis leads to end-stage renal disease (ESRD). SEMA7A may play a role in renal fibrosis and in ADPKD. METHODS: We evaluated Sema7a in a mouse model of renal fibrosis and determined the expression of SEMA7A in human ADPKD kidney...

BACKGROUND: Quantitative T 2 measurements are sensitive to intra- and extracellular water accumulation and myelin loss. Therefore, quantitative T 2 promises to be a good biomarker of disease. However, T 2 measurements require long acquisition times. PURPOSE: To accelerate T 2 quantification and subsequent generation of synthetic T 2 -weighted (T 2 -w) image contrast for clinical research and routine. To that end, a recently developed model-based approach for rapid T 2 and M 0 quantification (MARTINI) based on undersampling k-space, was extended by parallel imaging (GRAPPA) to enable high-resolution T 2 mapping with access to T 2 -w images in less than 2 minutes acquisition time for the entire brain...

BACKGROUND: The relationship between temporal progression of magnetic resonance elastography derived liver stiffness (MRE-LS) and progression of Fontan associated liver disease (FALD) is unknown. To assess this relationship, we hypothesized that progression of MRE-LS correlated with progression FALD severity and clinical outcomes. METHODS: Retrospective review of Fontan patients who had >1 liver MRE, 2010-2016. Annual change in MRE-LS was the quotient of the difference between baseline and subsequent MRE-LS, and the interval between scans...
