Assessment of volume status and volume responsiveness in the ICU: Protocol for an observational, multicentre cohort study.

Background: Expansion of the intravascular compartment is common to treat haemodynamic instability in ICU patients. The most useful and accurate variables to guide and evaluate a fluid challenge remain debated and incompletely investigated resulting in significant variability in practice. The analogue mean systemic pressure has been reported as a measure of the intravascular volume state.

Delayed medical emergency team calls and associated outcomes.

Objective: To determine whether there was an association between delayed medical emergency team calls and mortality after a medical emergency team review.

Design: This was a prospective observational study.

Setting: A university-affiliated tertiary referral hospital in Porto Alegre, Brazil.

Clinical characteristics and evolution of non-HIV-infected immunocompromised patients with an in-hospital diagnosis of tuberculosis.

Objective: To investigate the characteristics of and risk factors for mortality among non-HIV-infected immunocompromised patients with an in-hospital diagnosis of tuberculosis.

Methods: This was a two-year, retrospective cohort study of patients with an in-hospital diagnosis of tuberculosis. The predictive factors for mortality were evaluated.

Mortality among patients with tuberculosis requiring intensive care: a retrospective cohort study.

Background: To describe the characteristics of patients with tuberculosis (TB) requiring intensive care and to identify the factors that predicts in-hospital mortality in a city of a developing country with intermediate-to-high TB endemicity.

Methods: We conducted a retrospective, cohort study, between November 2005 and November 2007. The patients with TB requiring intensive care were included.

Factors associated with mortality in hospitalized patients with newly diagnosed tuberculosis.

The purpose of this study was to identify clinical and epidemiological factors associated with death in patients with an in-hospital diagnosis of tuberculosis (TB), in a city with a high prevalence of TB and human immunodeficiency virus (HIV) infection. The study was a retrospective, cohort study conducted at a general, tertiary-care, university-affiliated hospital. Patients who began treatment for TB after hospitalization were included.
