Background: Previous studies have reported higher circulating bile acid levels in patients with HCC compared to healthy controls. However, the association between prediagnostic bile acid levels and HCC risk among patients with cirrhosis is unclear.

Methods: We measured total BA (TBA) concentration in serum samples collected from a prospective cohort of patients with cirrhosis who were followed until the development of HCC, death, or last study date.

Background & Aims: Hepatocellular carcinoma (HCC) risk stratification is an urgent unmet need for cost-effective HCC screening and early detection in patients with cirrhosis to improve poor HCC prognosis.

Methods: Molecular (prognostic liver secretome signature with α-fetoprotein) and clinical (aMAP [age, male sex, albumin-bilirubin, and platelets] score) variable-based scores were integrated into PAaM (prognostic liver secretome signature with α-fetoprotein plus age, male sex, albumin-bilirubin, and platelets), which was subsequently validated in 2 phase 3 biomarker validation studies: the statewide Texas HCC Consortium and nationwide HCC Early Detection Strategy prospective cohorts, following the prospective specimen collection, retrospective blinded evaluation design. The associations between baseline PAaM and incident HCC were assessed using Fine-Gray regression, with overall death and liver transplantation as competing events.

Background And Aims: The original hepatocellular carcinoma early detection screening (HES) score, which combines alpha-fetoprotein (AFP) with age, alanine aminotransferase, and platelets, has better performance than AFP alone for early HCC detection. We have developed HES V2.0 by adding AFP-L3 and des-gamma-carboxy prothrombin to the score and compared its performance to GALAD and ASAP scores among patients with cirrhosis.

Background & Aims: In patients with cirrhosis, continued heavy alcohol consumption and obesity may increase risk of hepatocellular carcinoma (HCC). We examined whether germline susceptibility to hepatic steatosis not only independently predisposes to HCC but may also act synergistically with other risk factors.

Methods: We analyzed data from 1911 patients in 2 multicenter prospective cohort studies in the United States.

Background And Aims: Despite the substantial impact of environmental factors, individuals with a family history of liver cancer have an increased risk for HCC. However, genetic factors have not been studied systematically by genome-wide approaches in large numbers of individuals from European descent populations (EDP).

Approach And Results: We conducted a 2-stage genome-wide association study (GWAS) on HCC not affected by HBV infections.

Background: Inflammatory and metabolic biomarkers have been associated with hepatocellular cancer (HCC) risk in phases I and II biomarker studies. We developed and internally validated a robust metabolic biomarker panel predictive of HCC in a longitudinal phase III study.

Methods: We used data and banked serum from a prospective cohort of 2266 adult patients with cirrhosis who were followed until the development of HCC (n=126).

Background: Obesity is associated with an increased risk of developing cirrhosis. However, body mass index (BMI) and waist-to-hip ratio (WHR) may not be indicative of body composition parameters that predispose to cirrhosis. Bioimpedance analysis (BIA) is a noninvasive cost-efficient method for more detailed estimation of body composition.

Background & Aims: The available risk stratification indices for hepatocellular cancer (HCC) have limited applicability. We developed and externally validated an HCC risk stratification index in U.S.

Article Synopsis
  • Polygenic risk scores (PRS) show potential for improving the prediction of hepatocellular cancer (HCC) risk, but existing data primarily focuses on European populations, leaving a gap in multiethnic U.S. patient research.
  • A study involving 1,644 cirrhosis patients revealed that higher PRS correlates with increased HCC risk—specifically, a 134% risk increase per higher PRS unit and a two-fold risk in the highest PRS group compared to the lowest.
  • While the PRS alone had modest predictive accuracy, integrating it with traditional risk factors improved the model's predictive ability, suggesting PRS could enhance risk stratification for HCC among diverse cirrhosis patients in the

Article Synopsis
  • * Analysis of waitlist outcomes before and after the policy showed that the likelihood of receiving a liver transplant for HCC patients decreased by 20%, especially in low MELD regions where the drop was 41%.
  • * Despite a lower probability of transplantation for HCC patients after the policy, the situation for these patients relative to non-HCC patients improved, and there was no significant increase in the number of patients dropping off the waitlist.

Background And Aims: Etiological risk factors for cirrhosis have changed in the last decade. It remains unclear to what extent these trends in cirrhosis risk factors have changed HCC risk.

Approach And Results: We used data from two contemporary, prospective multiethnic cohorts of patients with cirrhosis: the Texas Hepatocellular Carcinoma Consortium Cohort and the Houston Veterans Administration Cirrhosis Surveillance Cohort.

Owing to the localized line-by-line and layer-by-layer style of material deposition, 3D printing remains an ideal candidate for fabrication of components with tailored properties (also referred to as functionally gradient components). The present work tries to exploit this advantage, in the extrusion-based 3D printing process, to fabricate components with varying set of properties at different locations. The implementation is done using Hilbert area-filling curves with the displacement per unit force (i.

Background: Recurrent hepatitis C virus (HCV) infection of transplanted liver allografts is universal in patients with detectable HCV viremia at the time of transplantation. Direct-acting antiviral (DAA) therapy has been adopted as the standard of care for recurrent HCV infection in the post-transplant setting. However, there are insufficient data regarding its efficacy in liver transplant (LT) recipients with a history of hepatocellular carcinoma (HCC), and the risk of HCC recurrence after DAA therapy is unknown.

Article Synopsis
  • A program was started to help liver transplant patients transition to adult care using important strategies called the Six Core Elements of Transition.
  • They checked if patients were ready to transition by giving them assessments and talking to a psychologist, aiming to improve their readiness scores.
  • After the program, many patients showed better scores and were followed up by adult care doctors, with some needing extra support after their transfer.

Objectives: The Texas Hepatocellular Carcinoma Consortium cohort study investigates risk factors of hepatocellular carcinoma (HCC) and biomarkers for early HCC detection in patients with liver cirrhosis.

Methods: Adult patients with liver cirrhosis are enrolled at 5 clinical centers from 3 cities in Texas, with a target of 5,000 patients. Clinical history, risk factor questionnaires, liver imaging, laboratory data, and blood samples were collected at enrollment and at each 6-month follow-up visit.

Objectives: Giant cell arteritis (GCA) is a vasculitis that affects large and medium sized arteries. The aetiology of GCA is unknown and numerous risk factors have been proposed. In this article, we evaluate the incidence of biopsy-positive GCA in Northern California and assess for seasonal variation.

Historically, visual acuity has been the benchmark for visual function. It is used to measure therapeutic outcomes for vision-related services, products and interventions. Quantitative measurement of suboptimal visual acuity can potentially be corrected optically with proper refraction in some cases, but in many cases of reduced vision there is something else more serious that can potentially impact other aspects of visual function such as contrast sensitivity, color discrimination, peripheral field of view and higher-order visual processing.

Background: Lower serum Cr levels in women as compared to men result in underestimation of renal dysfunction and lower model for end-stage liver disease-sodium scores leading to reduced access to liver transplantation in women compared to men with comparable hepatic dysfunction.

Aim: The aim of this study was to determine the gender differences in serum Cr, cystatin C, and other endogenous glomerular filtration rate (GFR) biomarkers, measured and estimated GFR, Cr clearance, and Cr production rates.

Methods: We measured GFR by iothalamate plasma clearance in 103 patients with cirrhosis and assessed gender differences in GFR, Cr clearance and production rate, serum Cr, cystatin C and other endogenous GFR biomarkers including beta-trace protein, beta-2 microglobulin, and dimethylarginines.
