Systemic antibiotics for preventing ventilator-associated pneumonia in comatose patients: a systematic review and meta-analysis.

Background: Early-onset ventilator-associated pneumonia (EO-VAP) is the leading cause of morbidity and mortality in comatose patients. However, VAP prevention bundles focus mainly on late-onset VAP and may be less effective in preventing EO-VAP in comatose patients. Systemic antibiotic administration at the time of intubation may have a role in preventing EO-VAP.

Predictors of tuberculosis treatment outcomes.

Objective: To analyze tuberculosis treatment outcomes and their predictors.

Methods: This was a retrospective longitudinal cohort study involving tuberculosis patients treated between 2004 and 2006 at the Instituto de Pesquisa Evandro Chagas, in the city of Rio de Janeiro. We estimated adjusted risk ratios (ARRs) for the predictors of treatment outcomes.
