Routine screening for Helicobacter pylori infection during hospitalization for myocardial infarction does not reduce the risk of upper gastrointestinal bleeding, according to findings from the HELP-MI SWEDEHEART trial, although secondary and subgroup analyses suggest potential clinically meaningful benefits.

New findings reveal a potential mechanism by which Helicobacter pylori exacerbates rheumatoid arthritis

A recent study found that the Helicobacter pylori genome evolves during disease progression and that these genomic changes select for effective colonizers of gastric metaplasia.

A large genome dataset investigates the evolutionary history of Helicobacter pylori and its links to human migration.
