The better to understand and address this problem, we began using the National Nosocomial Infection Surveillance (NNIS) system in five Brazilian hospitals in 1991. METHODS Data were collected prospectively according to the NNIS protocol, by using nosocomial infection(More)

SETTING All of the 11 general hospitals of Belo Horizonte that have more than 20 beds, from August 27 to October 5, 1992. RESULTS Of the 2,339 patients surveyed, 267 patients had(More)

Most molecular analyses, including phylogenetic inference, are based on sequence alignments. We present an algorithm that estimates relatedness between biomolecules without the requirement of sequence alignment by using a protein frequency matrix that is reduced by singular value decomposition (SVD), in a latent semantic index information retrieval system.(More)
OBJECTIVE To investigate preoperative predictive factors of severe perioperative intercurrent events and in-hospital mortality in coronary artery bypass graft (CABG) surgery and to develop specific models of risk prediction for these events, mainly those that can undergo changes in the preoperative period. METHODS We prospectively studied 453 patients who(More)
