Nucleos(t)ide Analog Treatment Discontinuation in Chronic Hepatitis B Virus Infection: A Systematic Literature Review.

Background And Aims: The aim of this systematic literature review (SLR) was to examine outcomes and associated predictors following nucleos(t)ide analog (NA) treatment cessation in adult patients with chronic hepatitis B virus infection.

Methods: The SLR was conducted according to PRISMA methodology. All included studies were quality assessed using appropriate scales or checklists.

Chronic Hepatitis B Costs and Healthcare Resource Utilization in a Japanese Patient Population: A Retrospective Cross-Sectional Analysis.

Introduction: Data on the economic burden of chronic hepatitis B infection in Japan are lacking. This study investigated healthcare resource utilization and costs of chronic hepatitis B infection and liver complications in Japan.

Methods: This non-interventional study used the Medical Data Vision database.

Association of Hepatitis B Surface Antigen Levels With Long-Term Complications in Chronic Hepatitis B Virus Infection: A Systematic Literature Review.

Chronic hepatitis B virus (HBV) infection is a global issue and can lead to cirrhosis and hepatocellular carcinoma (HCC). Hepatitis B surface antigen (HBsAg) is an important marker of HBV infection and HBsAg quantification could be a useful tool in clinical practice. This systematic literature review aimed to explore the association between HBsAg titres and long-term disease outcomes and evaluate the relationship between HBsAg titres, or changes in HBsAg titres, and clinical and treatment characteristics in patients with chronic HBV infection.

Absolute measurement of cellular activities using photochromic single-fluorophore biosensors and intermittent quantification.

Genetically-encoded biosensors based on a single fluorescent protein are widely used to visualize analyte levels or enzymatic activities in cells, though usually to monitor relative changes rather than absolute values. We report photochromism-enabled absolute quantification (PEAQ) biosensing, a method that leverages the photochromic properties of biosensors to provide an absolute measure of the analyte concentration or activity. We develop proof-of-concept photochromic variants of the popular GCaMP family of Ca biosensors, and show that these can be used to resolve dynamic changes in the absolute Ca concentration in live cells.
