BACKGROUND Nosocomial infection is an important public health problem in Brazil. 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)
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 assess the magnitude of nosocomial infections (NI) in general hospitals of Belo Horizonte. DESIGN Multicenter point-prevalence study of nosocomial infections. 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)
BACKGROUND A hospital-wide, traditional prospective surveillance for nosocomial infections was commenced in 1992 in Centro Geral de Pediatria in Minas Gerais, Brazil, to describe the epidemiology of nosocomial infection in this pediatric hospital and to implement cross-infection prevention and control policies. METHODS We performed a prospective cohort(More)
PRIMARY OBJECTIVE To determine whether using live actors to increase the reality of the scenario improves knowledge retention in Advanced Cardiac Life Support (ACLS) Courses. MAIN SECONDARY OBJECTIVES: To determine the effects of age, time since graduation from nursing or medicine, sex, medical specialty, and workplace in knowledge retention. METHODS From(More)
Phylogeny is an important field to understand evolution and the organization of life. However, most methods depend highly on manual study and analysis, making the construction of phylogeny error prone. Linear Algebra methods are known to be efficient to deal with the semantic relationships between a large number of elements in spaces of high dimensionality.(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)
OBJECTIVE To analyze infections of the surgical site among patients undergoing clean-wound surgery for correction of femoral fractures. METHODS This was a historical cohort study developed in a large-sized hospital in Belo Horizonte. Data covering the period from July 2007 to July 2009 were gathered from the records in electronic medical files, relating(More)
