Validação da Échelle Douleur Inconfort Nouveau-Né para a cultura brasileira

RESUMO Objetivo Avaliar a confiabilidade e a validade da versão brasileira da Échelle Douleur Inconfort Nouveau-Né, que mensura a dor prolongada em recém-nascidos. Método Estudo metodológico realizado junto com recém-nascidos. Para a coleta foram utilizadas as versões brasileiras da Échelle Douleur Inconfort Nouveau-Né e da Children’s and Infants’ Postoperative Pain Scale. Para a confiabilidade, foram consideradas a equivalência, mensurada pela concordância entre observadores, e a homogeneidade. Para avaliar a validade, foi considerada a abordagem de construto convergente correlacionando as versões brasileiras da Échelle Douleur Inconfort Nouveau-Né e da Children’s and Infants’ Postoperative Pain Scale. Resultados Compuseram a amostra final 96 recém-nascidos. Na avaliação da confiabilidade, o coeficiente de concordância entre observadores variou entre 0,64 e 0,85 para os itens que compõem o instrumento e 0,96 para o escore total. O alfa de Cronbach foi de 0,82. Na avaliação da validade convergente, o coeficiente de correlação de Spearman entre os valores encontrados para as duas escalas foi de 0,79 (p< 0,0001). Conclusão A versão brasileira da Échelle Douleur Inconfort Nouveau-Né é um instrumento confiável e válido para avaliar a dor prolongada em recém-nascidos

Evaluation of parameters related to libido and semen quality in Zebu bulls naturally infected with Trypanosoma vivax

BACKGROUND: Trypanosomiasis is a disease caused by Trypanosoma (Dutonella) vivax, a hemoprotozoa that can affect bovines. In South America, the sanguineous form is mechanically transmitted from one mammalian host (ruminant) to another by the bite of a blood-sucking insect or by needles contaminated with infected blood. The negative impact of the parasitosis caused by T. vivax infection on the reproductive activity of male and female ruminants is known to reduce fertility. In males, alterations such as degeneration, diffuse or interlobular inflammatory infiltrate found in ovine and bovine testicles, can affect fertility through decreased sperm quality. This study evaluated the impact of natural infection with T. vivax on Zebu bulls from the Central Station of Artificial Insemination (CSAI) with regard to libido and the negative effects caused by this protozoan on semen quality. METHODS: Blood samples of 44 animals were collected to evaluate the presence of the trypomastigote form of T. vivax in blood smears obtained from hematocrit and buffy coat, and antibody titer IgG anti T. vivax in indirect Immunoflorescence (IFI). Furthermore, data related to libido, ejaculate volume, spermatic concentration, and seminal vigor were recorded for these animals employing the criteria of the CSAI. RESULTS: Nine animals (20.45 %) showed T. vivax trypomastigotes and parasitemia between 0.02 and 0.07, and antibody titers from 1:80 to 1:320 in IFI. Twenty nine negative animals in parasitological tests were not reactive in IFI, and six animals presented the antibodies IgG anti T. vivax in IFI. Data on reproductive activity showed that animals infected with T. vivax have a decreased libido and an increased spermatic volume, whereas other factors related to the reproductive process such as spermatic concentration, motility and spermatic force, were unchanged in infected bulls. CONCLUSIONS: The T. vivax infection in Zebu bulls from CSAI caused patent parasitemia, induced a febrile state, promoted reduction in the libido and increased the ejaculate volume. These conditions together may account to decrease the performance of these animals
