Background And Aims: Gastric intestinal metaplasia (GIM) is a gastric cancer precursor. Narrow-band imaging (NBI) may improve detection of GIM. We compared detection of GIM with high-definition white-light (HD-WL) endoscopy, NBI, and mapping biopsies in a population with increased gastric cancer risk.

Background And Aim: Some studies suggest that narrow-band imaging (NBI) can be more accurate at diagnosing gastric intestinal metaplasia and dysplasia than white-light endoscopy (WLE) alone. We aimed to assess the real-time diagnostic validity of high resolution endoscopy with and without NBI in the diagnosis of gastric premalignant conditions and to derive a classification for endoscopic grading of gastric intestinal metaplasia (EGGIM).

Methods: A multicenter prospective study (five centers: Portugal, Italy, Romania, UK, USA) was performed involving the systematic use of high resolution gastroscopes with image registry with and without NBI in a centralized informatics platform (available online).

Background: A specific diagnosis of a lower respiratory viral infection is often difficult despite frequent clinical suspicion. This low diagnostic yield may be improved by use of sensitive detection methods and biomarkers.

Methods: The prevalence, clinical predictors and inflammatory mediator profile of respiratory viral infection in serious acute respiratory illness were investigated.

Background: Studies have reported the presence of KI polyomavirus (KIPyV) and WU polyomavirus (WUPyV) in respiratory secretions of young patients. So far, evidence has not supported a link between infections with either virus and respiratory tract disease; however, there has not been a large comparison of KIPyV-infected patients to age-matched patient groups.

Methods: A retrospective study comparing clinical aspects of KIPyV-positive patients with respiratory syncytial virus (RSV)-positive, WUPyV-positive, and respiratory-virus negative patients.
