OBJECTIVE To evaluate the characteristics and outcomes of patients with cancer admitted to several intensive care units. Knowledge on patients with cancer requiring intensive care is mostly restricted to single-center studies. DESIGN : Prospective, multicenter, cohort study. SETTING Intensive care units from 28 hospitals in Brazil. PATIENTS A total of(More)
BACKGROUND This study was undertaken to evaluate the clinical characteristics and outcomes of patients with cancer requiring nonpalliative ventilatory support. METHODS This was a secondary analysis of a prospective cohort study conducted in 28 Brazilian ICUs evaluating adult patients with cancer requiring invasive mechanical ventilation (MV) or(More)
INTRODUCTION Sedation overuse is frequent and possibly associated with poor outcomes in the intensive care unit (ICU) patients. However, the association of early oversedation with clinical outcomes has not been thoroughly evaluated. The aim of this study was to assess the association of early sedation strategies with outcomes of critically ill adult(More)
BACKGROUND AND OBJECTIVES Sepsis represents the major cause of death in the ICUs all over the world. Many studies have shown an increasing incidence over time and only a slight reduce in mortality. Many new treatment strategies are arising and we should define the incidence and features of sepsis in Brazil. METHODS Prospective cohort study in sixty-five(More)
PURPOSE To identify the veins draining from the pancreatic tail to the lienal vein and its possible relationship with the loss of the distal splenorenal shunt selectivity. METHODS Thirty eight human blocks including stomach, duodenum, spleen, colon and pancreas, removed from fresh corpses, were studied with the replenish and corrosion technique, using(More)
INTRODUCTION Cancer patients are at risk for severe complications related to the underlying malignancy or its treatment and, therefore, usually require admission to intensive care units (ICU). Here, we evaluated the clinical characteristics and outcomes in this subgroup of patients. MATERIALS AND METHODS Secondary analysis of two prospective cohorts of(More)
OBJECTIVE To study the functional and morphological features of splenic autoimplants in rats subjected, or not, to postoperative hyperbaric oxygen therapy. METHODS One hundred and five male Wistar rats, weighing 251.6 g ± 29.5 g, were studied ot early (11th day) and late (70th day ) postoperative periods.

OBJECTIVE To evaluate the incidence of urinary tract infections due to Trichosporon spp. in an intensive care unit. METHODS This descriptive observational study was conducted in an intensive care unit between 2007 and 2009. All consecutive patients admitted to the intensive care unit with a confirmed diagnosis were evaluated. RESULTS Twenty patients(More)
Removal of low-density lipoproteins from plasma by dextran sulfate adsorption (DSA) in FH patients entails a decrease in plasma levels of thyroid hormones (-28.5% and -18.7%, respectively, for T3 and T4). This suggests that FH patients have a greater than normal fraction of thyroid hormones bound to lipoproteins, due to their expanded lipoprotein pool.
