Species and biotypes of Streptococcus bovis causing infective endocarditis.

Introduction: Streptococcus bovis/equinus complex (SBEC) is a major cause of infective endocarditis (IE), although its incidence varies greatly depending on the geographical area. The characteristics of IE caused by Streptococcus gallolyticus susp. gallolyticus are well known; there are hardly any descriptions of IE caused by other species or biotypes.

Derivation and external validation of a simple prediction rule for the development of respiratory failure in hospitalized patients with influenza.

Background: Influenza viruses cause seasonal epidemics worldwide with a significant morbimortality burden. Clinical spectrum of Influenza is wide, being respiratory failure (RF) one of its most severe complications. This study aims to elaborate a clinical prediction rule of RF in hospitalized Influenza patients.

Relationship among Subsp. , and Colorectal Neoplasms in Recurrent Endocarditis: A Historical Case Series.

Objectives: The role of colorectal neoplasms (CRN) as a common potential source of recurrent subsp. (SGG) and (EF) endocarditis remains unstudied. We aimed to investigate what proportion of episodes of recurrent endocarditis are caused by a succession of SGG and EF, or vice versa, and to assess the role of a colonic source in such recurrent episodes.
