Objective We explored clinical implications of the new definition metabolic dysfunction-associated steatotic liver disease (MASLD) by assessing its prevalence and associated cardiovascular (CVD) risk. Design From nationwide health screening data, we identified 9 775 066 adults aged 20–79 who underwent examination in 2009. Participants were categorised into four mutually exclusive groups: (1) MASLD; (2) MASLD with increased alcohol intake (MetALD); (3) other combined aetiology (the three...

Hepatocellular carcinoma (HCC) presents unique challenges in both the elderly and adolescent/young adult (AYA) populations, requiring distinct management approaches. Recent epidemiological data show an increasing incidence of HCC age groups, with cases rising significantly AYA showing trends specific regions. The clinical characteristics treatment considerations vary substantially among these populations. Elderly patients typically present hepatitis C virus infection, metabolic...

ABSTRACT Background Antiviral therapy (AVT) reduces the risk of hepatitis B virus–related hepatocellular carcinoma (HCC). Aims The difference in HCC after surface antigen (HBsAg) seroclearance to AVT status was explored. Methods Patients with chronic who achieved HBsAg were retrospectively evaluated. primary outcome development seroclearance. Results Of study population, 1280 (84.2%) and 241 (15.8%) patients without (spontaneous clearance group) (AVT‐induced group), respectively. cumulative...

ABSTRACT Background &amp; Aims Non‐selective β‐blockers (NSBBs) and endoscopic variceal‐ligation (EVL) have similar efficacy preventing first variceal bleeding. Compensated decompensated cirrhosis are markedly different stages, which may impact treatment outcomes. We aimed to assess the of NSBBs vs EVL on survival in patients with high‐risk varices without previous bleeding, stratifying risk according compensated/decompensated stage cirrhosis. Methods By systematic review, we identified RCTs...

Background/Aims: Transarterial radioembolization (TARE) has shown promising results in treating advanced hepatocellular carcinoma (HCC) with portal vein tumor thrombosis (PVTT). However, whether TARE can provide superior or comparable outcomes to tyrosine kinase inhibitor (TKI) patients HCC and PVTT remains unclear. We compared the of TKI therapy treatment-naïve locally segmental lobar PVTT.Methods: This multicenter study included 216 initially treated (n=124) (sorafenib lenvatinib; n=92)...

Background: The platelet-to-white blood cell ratio (PWR) is a hematologic marker of the systemic inflammatory response. Recently, PWR was revealed to have role as an independent prognostic factor for mortality in patients with hepatitis B virus (HBV)-related acute-on-chronic failure (ACLF) and HBV-related liver cirrhosis (LC) acute decompensation (AD). However, still needs be investigated LC AD. In this study, we analyzed whether could stratify risk adverse outcomes (death or transplantation...
