Background: Direct acting antivirals (DAAs) have demonstrated remarkable efficacy, in achieving hepatitis C viral (HCV) elimination rates higher than 90%. One particular concern associated with treatment failure is the emergence of resistance associated substitutions (RASs) in the genome. The occurrence of RASs highlights the adaptability and resilience of the HCV.

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.

Cathinone metabolism and biliary excretion in an ex-vivo pig liver model: Example of 4-Cl-PVP and eutylone.

Food Chem Toxicol

January 2025

INSERM, Univ Rennes, INRAE, Institut NUMECAN (Nutrition, Métabolismes et Cancer) UMR_A 1341, UMR_S 1317, F-35000, Rennes, France; Laboratoire de toxicologie biologique et Médico-légale, CHU Rennes, Rennes, France.

Objective: Recently, the pig liver model perfused ex vivo using a normothermic machine perfusion (NMP) has been proposed as a suitable model to study xenobiotic metabolism and biliary excretion. The aim of our study is to describe the metabolism of NPS such as cathinones (with a focus on 4-Cl-PVP and eutylone) in blood and bile, using a normothermic perfused pig liver model.

Methods: Livers (n = 4) from male large white pigs, 3-4 months of age and weighing approximately 75-80 kg, were harvested and reperfused onto an NMP (LiverAssist®, XVIVO) using autologous whole blood at 38 °C.

Hepatitis B elimination objectives can only be realised if new patient linkage to care is matched by long-term patient retention in care. We previously showed in adult chronic hepatitis B (CHB) patients that retention in care was inferior in younger patients and in patients from non-Asian ethnicities. The present study explores further the rates and determinants of loss to follow-up in a cohort of 271 young patients (aged 16-21 years at baseline).

Tumor initiating cells escape tumor immunity via CCL8 from tumor-associated macrophages in mice.

J Clin Invest

January 2025

Tumor-initiating cells (TICs) play a key role in cancer progression and immune escape. However, how TICs evade immune elimination remains poorly characterized. Combining single-cell RNA sequencing (scRNA-seq), dual-recombinase-based lineage tracing, and other approaches, we identified a WNT-activated subpopulation of malignant cells that act as TICs in vivo.
