Commercial enzyme-linked immunosorbent assay versuspolymerase chain reaction for the diagnosis of chronic Chagas disease: a systematic review and meta-analysis

Chronic Chagas disease diagnosis relies on laboratory tests due to its clinical characteristics. The aim of this research was to review commercial enzyme-linked immunosorbent assay (ELISA) and polymerase chain reaction (PCR) diagnostic test performance. Performance of commercial ELISA or PCR for the diagnosis of chronic Chagas disease were systematically searched in PubMed, Scopus, Embase, ISI Web, and LILACS through the bibliography from 1980-2014 and by contact with the manufacturers. The risk of bias was assessed with QUADAS-2. Heterogeneity was estimated with the I2 statistic. Accuracies provided by the manufacturers usually overestimate the accuracy provided by academia. The risk of bias is high in most tests and in most QUADAS dimensions. Heterogeneity is high in either sensitivity, specificity, or both. The evidence regarding commercial ELISA and ELISA-rec sensitivity and specificity indicates that there is overestimation. The current recommendation to use two simultaneous serological tests can be supported by the risk of bias analysis and the amount of heterogeneity but not by the observed accuracies. The usefulness of PCR tests are debatable and health care providers should not order them on a routine basis. PCR may be used in selected cases due to its potential to detect seronegative subjects.

Superfícies do ambiente hospitalar como possíveis reservatórios de bactérias resistentes: uma revisão

O principal objetivo deste estudo é identificar, na literatura, artigos sobre a ocorrência de contaminação das superfícies inanimadas e uma possível disseminação de bactérias resistentes no ambiente hospitalar. Realizou-se um levantamento bibliográfico de artigos publicados nas bases de dados LILACS, MEDLINE, Science Direct, SCOPUS e ISI Web of Knowledge, entre 2000 e 2008. Foram selecionados e analisados vinte e um artigos. Nos estudos analisados, realçou-se a presença de bactérias em monitores, grades de cama, mesas, torneiras, telefones, teclados de computador e outros objetos. Houve predominância de Staphylococcus aureus resistente à meticilina, Clostridium difficile, Acine-to-bacter baumannii e Enterococcus resistentes à vancomicina, sendo fator preditivo a ocupação prévia por pacientes colonizados por tais microrganismos. Verificou-se semelhança entre as cepas isoladas de pacientes colonizados e/ou infectados e as cepas do ambiente por tipificação molecular. Essas evidências reforçam a necessidade de conhecimento e controle de fontes de patógenos no ambiente hospitalar.

Early postnatal hospital discharge: the consequences of reducing length of stay for women and newborns

The objective of this study is to examine the literature and identify most salient outcomes of early postnatal discharge for women, newborns and the health system. An electronic search strategy was designed including the following sources: Web of Science, Scopus, ProQuest and PubMed/MEDLINE, using the following terms: (early AND discharge) OR (length AND stay) AND (postpartum OR postnatal) AND (effect* OR result OR outcome). Content analysis was used to identify and summarise the findings and methods of the research papers. The evidence available is not enough to either reject or support the practice of early postnatal discharge; different studies have reported different outcomes for women and newborns. The need of systematic clinical research is discussed.

Ozônio na esterilização de produtos para assistência à saúde: revisão integrativa da literatura

Estudo de revisão integrativa da literatura com o objetivo de buscar evidências que subsidiem a incorporação do ozônio como agente esterilizante de produtos para saúde. A busca foi realizada nas bases MEDLINE, SCOPUS, COCHRANE, COMPENDEX, INSPEC E ENGINEERING RESEARCH DATABASE, utilizando-se os descritores ozone e sterilization. Foram obtidas cinco publicações, entre 1990 e 2008, que testaram o ozônio como esterilizante. Todas utilizaram o mesmo tipo de investigação (experimental laboratorial) e alcançaram esterilização pelo ozônio, porém com variados escopos e produtos testados, além de diversos procedimentos metodológicos. Tendo em vista a incessante tecnologia de novos produtos, com ampla variedade de conformações e matéria-prima, os achados denotam o ozônio um método promissor, porém ainda em fase inicial de investigação. Mais estudos experimentais ainda são necessários, de maneira a subsidiar evidências mais amplas sobre suas possibilidades e limitações.

Strategies for self-management support by patients with stroke: integrative review

OBJECTIVE To analyze strategies for self-management support by patients with stroke in the light of the methodology of the five A's (ask, advice, assess, assist and arrange). METHODS Integrative review conducted at the following databases CINAHL, SCOPUS, PubMed, Cochrane and LILACS. RESULTS A total of 43 studies published between 2000 and 2013 comprised the study sample. All proposed actions in the five A's methodology and others were included. We highlight the Assist and Arrange, in which we added actions, especially with regard to the use of technological resources and joint monitoring between patients, families and professionals. No study included all five A's, which suggests that the actions of supported self-management are developed in a fragmented way. CONCLUSION The use of five A's strategy provides guidelines for better management of patients with stroke with lower cost and higher effectiveness.
