Factors influencing hepatitis B vaccination intention and behavior among college students in Tibet: Insights from the expanded theory of planned behavior.

Hepatitis B (Hep B) remains a critical public health issue globally, particularly in Tibet, where vaccination rates and influencing factors among college students are yet understudied. This study applies a cross-sectional design to investigate the Hep B vaccination rate among 1,126 college students in Tibet and utilizes the expanded theory of planned behavior (ETPB) to identify vaccination behavior intention (BI) and vaccination behavior (VB). Stratified cluster sampling across three universities was used to assess behavioral attitudes (BA), subjective norms (SN), perceived behavioral control (PBC), past vaccination history (PVH) and vaccination knowledge (VK), and used structural equation modeling (SEM) for model validation and multi-group comparison.

Hepatitis C virus (HCV) elimination in the care cascades for patients receiving invasive procedures remains elusive. This study aimed to evaluate the efficacy of HCV-free Endoscope Procedures Project (CEPP) in the effort toward hospital HCV micro-elimination in Taiwan. An electronic medical record (EMR)-based remind system was introduced into gastrointestinal, surgical, urological, and gynecological departments prior to the endoscopy procedures.

February 2025
Liver Research Center, Beijing Friendship Hospital, Capital Medical University, Beijing, China.
Background And Aim: Discriminating between idiosyncratic drug-induced liver injury (DILI) and autoimmune hepatitis (AIH) is critical yet challenging. We aim to develop and validate a machine learning (ML)-based model to aid in this differentiation.
Methods: This multicenter cohort study utilised a development set from Beijing Friendship Hospital, with retrospective and prospective validation sets from 10 tertiary hospitals across various regions of China spanning January 2009 to May 2023.
Clonal analysis of SepSecS-specific B and T cells in autoimmune hepatitis.
J Clin Invest
January 2025
Institute for Research in Biomedicine (IRB), Bellinzona, Switzerland.
Autoimmune hepatitis (AIH) is a rare chronic inflammatory liver disease characterized by the presence of autoantibodies, including those targeting O-phosphoseryl-tRNA:selenocysteine-tRNA synthase (SepSecS), also known as soluble liver antigen (SLA). Anti-SepSecS antibodies have been associated with a more severe phenotype, suggesting a key role for the SepSecS autoantigen in AIH. To analyze the immune response to SepSecS in patients with AIH at the clonal level, we combined sensitive high-throughput screening assays with the isolation of monoclonal antibodies (mAbs) and T cell clones.

January 2025
How are autoreactive T cells induced and regulated in patients with autoimmune disease? This question lies at the core of understanding autoimmune disease pathologies, yet it has remained elusive due to host variability and the complexity of the immune system. In this issue of the JCI, Kramer and colleagues used autoimmune hepatitis (AIH) as a model to explore the maintenance of autoreactive CD4+ T cells specific to O-phosphoseryl-tRNA:selenocysteine tRNA synthase (SepSecS). The findings provide insight into the interaction between T cells and B cells in AIH pathogenesis that may reflect a shared mechanism among other autoimmune diseases.
