Scientific Literature on the Reliability and Validity of the Manchester Triage System (MTS) Protocol: A Integrative Literature Review

OBJECTIVE To analyze the scientific production about the validity and reliability of the Manchester Triage System (MTS) protocol. METHOD A descriptive study of an integrative literature review. Articles on the validity and reliability of the MTS developed with children and adults published between 1999 and 2013 were included. RESULTS 14 articles were selected from a total of 8438, nine of validity and five of reliability. The reliability of the MTS ranged from moderate to almost perfect, with higher intra-evaluation. Regarding validity, the results seem to point to equivalent and satisfactory sensibility and specificity levels of the MTS. The instrument proved to be a good predictor of the need for hospitalization and of hospital mortality. CONCLUSION The reliability and validity of the MTS obtained in the studies is varied. It is recommended that new studies indicate necessary modifications to the MTS so that it is more safely used by nurses.

Espécies de Adelpha Hübner, [1819] (Lepidoptera, Nymphalidae, Limenitidinae) ocorrentes no Rio Grande do Sul, Brasil

Species of Adelpha Hübner, [1819] (Lepidoptera, Nymphalidae, Limenitidinae) occurring in Rio Grande do Sul State, Brazil. Based on literature, collections and sampled butterflies, a list of twelve species of Adelpha Hübner occurring in Rio Grande do Sul State is presented, including host plants. Adelpha epizygis Fruhstorfer, [1916], Adelpha falcipennis Fruhstorfer, [1916], Adelpha goyama Schaus, 1902 and Adelpha isis (Drury, 1782) are new reports to Rio Grande do Sul. The species are illustrated and keyed.

Laboratório químico-prático do Rio de Janeiro: primeira tentativa de difusão da Química no Brasil (1812- 1819)

Until the present date, historians of science have described inaccurately the first laboratory created in Brazil for establishing and divulging Chemistry, namely the "Laboratório Químico-Prático do Rio de Janeiro". During recent research carried out in the Arquivo do Museu Imperial (Petrópolis, RJ), I localized a document entitled "Ensaio histórico analítico das operações do Laboratório Químico-Prático do Rio de Janeiro", which allowed me to gain the relevant information to correct some of the observations made in the first chronicles.

Restriction site heteroplasmy in the mitochondrial DNA of Brycon opalinus (Cuvier, 1819) (Characiformes, Characidae, Bryconiae)

Homoplasmy is a feature usually found in the mtDNA of higher animal taxa. On the other hand, the presence of two classes of mtDNA in the same cell or organism is rare and may appear in length or site variation. Data from mtDNA RFLP analysis of Brycon opalinus populations (Cuvier, 1819; Characiformes, Characidae, Bryconinae) revealed site heteroplasmy from endonuclease NheI digestion. Southern blotting hybridization was used to survey a total of 257 specimens with 24 restriction enzymes. Three different restriction fragment patterns of mtDNA were obtained from NheI digestion. Two individuals from hatchery broodstock were found to have two of them. NheI digests of heteroplasmic individuals yielded two fragments of approximately 1180 and 1260 bp. Despite the low frequency of this type of heteroplasmy in the whole B. opalinus population, the presence of site heteroplasmy in this species supports the evidence of this phenomenon in lower vertebrate groups.
