Hepatocellular carcinoma (HCC) surveillance is recommended by liver professional societies but lacks broad acceptance by several primary care and cancer societies due to limitations in the existing data. We convened a diverse multidisciplinary group of cancer screening experts to evaluate current and future paradigms of HCC prevention and early detection using a rigorous Delphi panel approach. The experts had high agreement on twenty-one statements about primary prevention, HCC surveillance benefits, HCC surveillance harms, and the evaluation of emerging surveillance modalities.

We aimed to validate these criteria by determining whether they are associated with risk of adverse outcomes.
Methods And Results: Patients without prior hepatic decompensation or hepatocellular carcinoma (HCC) who underwent LS and platelet measurements (n=17,076), were categorized as follows: no cACLD (LS 2.
Introduction: The controlled attenuated parameter (CAP) score derived from vibration-controlled transient elastography (VCTE, i.e., FibroScan) is a well-validated marker of hepatic steatosis.

We aimed to develop models to predict 30-day COVID-19 hospitalization and death in the Omicron era for contemporary clinical and research applications.
Methods: We used comprehensive electronic health records from a national cohort of patients in the Veterans Health Administration (VHA) who tested positive for SARS-CoV-2 between March 1, 2022, and March 31, 2023.
Introduction: COVID-19 triggers prothrombotic and proinflammatory changes, with thrombotic disease prevalent in up to 30% SARS-CoV-2 infected patients. Early work suggests that aspirin could prevent COVID-19 related thromboembolic disorders in some studies but not others. This study leverages data from the largest integrated healthcare system in the United States to better understand this association.

We aimed to determine the prevalence, clinical characteristics, surveillance rates, treatment allocation, and outcomes of alcohol-associated HCC.
Methods: Medline and Embase were searched from inception to January 2023.
Importance: The risk of hepatocellular carcinoma (HCC) declines over time after hepatitis C virus (HCV) cure by direct-acting antiviral (DAA) therapies. Liver society guidelines recommend continuing HCC screening for these patients, but data on screening outcomes are lacking.
Objective: To evaluate the association of HCC screening after HCV cure with overall survival.
Geographic variation in hardship, especially health-related hardship, was identified prior to and during the pandemic, but we do not know whether this variation is consistent among Veterans Health Administration (VHA)-enrolled veterans, who reported markedly high rates of financial hardship during the pandemic, despite general and veteran-specific federal policy efforts aimed at reducing hardship. In a nationwide, regionally stratified sample of VHA-enrolled veterans, we examined whether the prevalence of financial hardship during the pandemic varied by US Census region. We found veterans in the South, compared with those in other census regions, reported higher rates of severe-to-extreme financial strain, using up all or most of their savings, being unable to pay for necessities, being contacted by collections, and changing their employment due to the kind of work they could perform.

Methods: We conducted a target trial emulation study in the Veterans Health Administration comparing nirmatrelvir-ritonavir treated versus matched untreated veterans at risk for severe COVID-19 who tested positive for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) from April 2022 through March 2023.
Background: Hepatocellular carcinoma (HCC) surveillance in patients with cirrhosis is associated with improved survival. Provision of HCC surveillance is low in the US, particularly in primary care settings.
Aims: To evaluate current hepatitis C virus (HCV) and HCC surveillance practices and physician attitudes regarding HCC risk-stratification among primary care and subspecialty providers.
Background: The Veterans Health Administration provides care to more than 100,000 Veterans with cirrhosis.
Aims: This implementation evaluation aimed to understand organizational resources and barriers associated with cirrhosis care.
Methods: Clinicians across 145 Department of Veterans Affairs (VA) medical centers (VAMCs) were surveyed in 2022 about implementing guideline-concordant cirrhosis care.
Importance: Research demonstrates that SARS-CoV-2 infection is associated with increased risk of all-cause hospitalization. However, no prior studies have assessed the association between SARS-CoV-2 and potentially preventable hospitalizations-that is, hospitalizations for conditions that can usually be effectively managed in ambulatory care settings.
Objective: To examine whether SARS-CoV-2 is associated with potentially preventable hospitalization in a nationwide cohort of US veterans.
Significance: The molecular mechanisms driving the progression from nonalcoholic fatty liver (NAFL) to fibrosing steatohepatitis (NASH) are insufficiently understood. Techniques enabling the characterization of different lipid species with both chemical and spatial information can provide valuable insights into their contributions to the disease progression.
Aim: We extend the utility of stimulated Raman scattering (SRS) microscopy to characterize and quantify lipid species in liver tissue sections from patients with NAFL and NASH.
Background: Unhealthy alcohol use (UAU) is particularly dangerous for people with chronic liver disease. Liver clinics may be an important setting in which to provide effective alcohol-related care by integrating evidence-based strategies, such as brief intervention and medications for alcohol use disorder. We conducted qualitative interviews with clinical stakeholders and patients at liver clinics in four Veterans Health Administration (VA) medical centers to understand barriers and facilitators of integrating alcohol-related care and to support tailoring of a practice facilitation implementation intervention.

Objective: To determine the rates, clinical setting, risk factors, and symptoms associated with the documentation of International Statistical Classification of Diseases Tenth Revision (ICD-10), code U09.9 for post-COVID-19 condition after acute infection.
Background: It is unclear whether the risk of hepatocellular carcinoma (HCC) decreases over time following hepatitis C virus (HCV) eradication.
Aim: To determine if patients who have accrued longer time since sustained virologic response (SVR) have a lower risk of HCC than those with less time since SVR METHODS: We conducted a retrospective cohort study of all HCV-infected Veterans Affairs patients who achieved SVR before 1 January 2018 and remained alive without a diagnosis of HCC as of 1 January 2019 (n = 75,965). We ascertained their baseline characteristics as of 1 January 2019 (time zero), including time accrued since SVR and followed them for the subsequent 12 months for incident HCC.
Background: COVID-19 has been linked to the development of many post-COVID-19 conditions (PCCs) after acute infection. Limited information is available on the effectiveness of oral antivirals used to treat acute COVID-19 in preventing the development of PCCs.
Objective: To measure the effectiveness of outpatient treatment of COVID-19 with nirmatrelvir-ritonavir in preventing PCCs.
