Hepatitis B virus (HBV) infection is a major health problem, causing thousands of deaths each year worldwide. Although current medications can often inhibit viral replication and reduce the risk of liver carcinoma, several obstacles still hinder their effectiveness. These include viral resistance, prolonged treatment duration, and low efficacy in clearing viral antigens. To address these challenges in current HBV treatment, numerous approaches have been developed with remarkable success. Among these strategies, small-interfering RNA (siRNA) stands out as one of the most promising therapies for hepatitis B. However, naked siRNAs are vulnerable to enzymatic digestion, easily eliminated by renal filtration, and unable to cross the cell membrane due to their large, anionic structure. Therefore, effective delivery systems are required to protect siRNAs and maintain their functionality. In this review, we have discussed the promises of siRNA therapy in treating HBV, milestones in their delivery systems, and products that have entered clinical trials. Finally, we have outlined the future perspectives of siRNA-based therapy for HBV treatment.

This study evaluated the association between HIV risk perception and sociodemographic and behavioral characteristics among cisgender female sex workers in the five regions of Brazil. A cross-sectional, multicenter study using respondent-driven sampling was used. Sex workers over 18 years of age and who reported commercial sex in the past four months were included.

Enteroviruses can infect various human organs, causing diseases such as meningitis, the common cold, hand-foot-and-mouth disease, myocarditis, pancreatitis, hepatitis, poliomyelitis, sepsis, and type 1 diabetes. Currently, there are no approved treatments for enterovirus infections. In this study, we identified a synergistic combination of orally available, safe-in-man pleconaril, AG7404, and mindeudesivir, that at non-toxic concentrations effectively inhibited enterovirus replication in human cell and organoid cultures.

Duck Hepatitis B virus (DHBV) infection model is extensively utilized as an animal model for studying human hepatitis B virus infection and for comparative research. 557 liver samples from geese and ducks were collected in parts of Guangdong province, southern China. The overall prevalence of DHBV was 45.

Background: This study examines Hepatitis C virus (HCV) screening scenarios to meet World Health Organization (WHO) elimination targets (incidence ≤5 per 100,000, mortality ≤2 per 100,000) and assesses their timeframes and cost-effectiveness.
Methods: A closed cohort model of Koreans aged 30-79 in 2020 projected HCV incidence and mortality over 20 years. Economic evaluations used a dynamic transmission model, considering prevalent and annual incident cases.

Background And Aims: We investigated associations between body mass index (BMI) and hepatocellular carcinoma (HCC) in patients with hepatitis B (HBV) C (HCV) virus infection, alcoholic liver disease (ALD), non-alcoholic fatty liver disease (NAFLD), and liver cirrhosis (LC).
Methods: We followed 350,608 Korean patients with liver disease who underwent routine health examinations from 2003-2006 until December 2018 via national hospital discharge records. Multivariable adjusted hazard ratios (HRs) per 5-kg/m2 BMI increase (BMI ≥25 kg/m2) for HCC risk were calculated using Cox models.
