Introduction: Alcohol-associated liver disease (ALD) disproportionately impacts men, racial and ethnic minorities, and individuals of low socioeconomic status; however, it's unclear how recent increases in ALD burden have impacted these disparities. We aimed to describe trends in racial, ethnic and socioeconomic disparities in alcohol-associated hospital encounters.
Methods: We conducted a retrospective cohort study of adult hospital encounters with alcohol-associated diagnoses from three health systems between January 2016 and December 2021.
Background: Racial and ethnic disparities have been reported for HCC prognosis, although few studies fully account for clinically important factors and social determinants of health, including neighborhood socioeconomic status.
Methods: We conducted a retrospective multicenter cohort study of patients newly diagnosed with HCC from January 2010 through August 2018 at 4 large health systems in the United States. We used multivariable logistic regression and cause-specific Cox proportional hazard models to identify factors associated with early-stage HCC presentation and overall survival.
Purpose: MRI is a potential alternative to ultrasound for hepatocellular carcinoma (HCC) detection. We evaluated the impact of ultrasound and dynamic abbreviated MRI (AMRI) exam quality on early-stage HCC detection.
Methods: We conducted a multicenter case-control study among patients with cirrhosis (cases with early-stage HCC per Milan Criteria; controls without HCC) who underwent both a liver ultrasound and dynamic contrast-enhanced (DCE) AMRI within 6 months in 2012-2019.
Background & Aims: Guidelines recommend that sub-centimeter nodules on ultrasound be followed with short-interval surveillance ultrasound, given assumed low risk of hepatocellular carcinoma (HCC) and suboptimal diagnostic imaging performance in lesions <1 cm. We performed a systematic review to estimate HCC risk among patients with cirrhosis and sub-centimeter nodules detected on ultrasound.
Methods: We systematically searched Ovid MEDLINE and EMBASE databases for relevant articles published between January 2005 and July 2024.
Article Synopsis
- The study investigates how nativity, neighborhood socioeconomic status (nSES), and ethnic enclave residency affect survival rates in Hispanic patients with hepatocellular carcinoma (HCC).
- Among nearly 10,000 Hispanic patients analyzed, foreign-born individuals exhibited lower mortality rates despite having less favorable disease presentations and treatment access.
- The results indicate that while higher nSES is linked to improved survival, enclave residency alone does not significantly impact outcomes, suggesting a need for further research into the complex interplay of ethnicity, nativity, and neighborhood conditions.
