Reação de fase aguda e sua relação com o desempenho de cavalos em competição de longa distância / Acute phase reaction and its relationship with performance horses competing long distance

O exercício físico é um dos estímulos fisiológicos mais estressantes que um animal pode sofrer e, dependendo de sua intensidade, sugere-se que possa gerar uma reação mediada por proteínas de fase aguda (PFA). O objetivo deste estudo foi caracterizar a reação de fase aguda e sua relação com o desempenho de cavalos submetidos a uma competição de longa distância. O experimento foi desenvolvido durante a Marcha de Resistência anual promovida pela Associação Brasileira de Criadores de Cavalos Crioulos (ABCCC), composta por um percurso de 750km percorrido durante 15 dias. Foram avaliados 23 equinos, os quais foram divididos em dois grupos, sendo o grupo 1 composto pelos 10 primeiros colocados na competição e o grupo 2 formado pelos 13 animais que concluíram a competição em colocações inferiores ou foram desclassificados antes de terminar a prova. Efetuaram-se coletas sanguíneas em repouso (dia 0) e no último dia de competição, e foi realizado o teste de eletroforese em gel de poliacrilamida contendo dodecil sulfato de sódio (SDS-PAGE) para identificar as proteínas (albumina, haptoglobina, ceruloplasmina, transferrina, imunoglobulina G, imunoglobulina A, glicoproteína ácida e proteína de peso molecular de 23kDa). Os resultados demonstraram que o exercício físico imposto influenciou de forma significativa (P<0,0001) as concentrações séricas de haptoglobina, ceruloplasmina, imunoglobulina A, glicoproteína ácida e proteína de peso molecular de 23kDa. Quando comparados os resultados dos grupos estudados, observou-se que a concentração de haptoglobina após a competição foi superior no grupo de animais com baixo desempenho (grupo 2). Conclui-se que a competição de longa duração é capaz de gerar reação de fase aguda e que o monitoramento da concentração de haptoglobina pode ser um sinalizador de processo inflamatório e baixo desempenho.(AU)

Exercise is one of the most stressful physiologic stimuli that an animal might suffer, depending on its intensity it may generate a reaction mediated by acute phase proteins (APP). The aim of this study was to characterize the acute phase reaction and its relation to performance horses subjected to long distance competition. The experiment was conducted during the annual March of Resistance promoted by the Brazilian Association of Crioulo Horse Breeders (ABCCC), composed of a 750km route traveled during 15 days. 23 horses which were divided in two groups, one group composed by the 10 best placed horses and the second group consisting of 13 animals that have completed the competition in other positions or were disqualified before concluding the race were evaluated. All horses at the beginning of the competition (day 0) and on the last day of competition were subjected to collection of blood and SDS-polyacrylamide gel (SDS-PAGE) electrophoresis was used to measure APPs concentrations (albumin, ceruloplasmin, transferrin, haptoglobin, acid glycoprotein, immunoglobulin G, immunoglobulin A and a protein with molecular weight of 23 kDa). By the evaluation of the results, it was observed that exercise had a highly significant influence (P<0.0001) in the serum concentrations of the ceruloplasmin, haptoglobin, acid glycoprotein, immunoglobulin A and protein with molecular weight of 23kDa. When comparing the results of the study groups it was observed that the concentration of haptoglobin after the competition was higher in the group of animals with low performance (group 2). We conclude that the long term competition is able to generate acute phase reaction and monitoring the concentration of haptoglobin may be an indicator of inflammation and low performance.(AU)

Mortalidad perinatal en gestaciones múltiples: Hospital Miguel Servet, Zaragoza, España: 2000-2009 / Perinatal mortality in multiple pregnancies: Hospital Miguel Servet, Zaragoza, España: 2000-2009

Objetivos: Evaluar la mortalidad perinatal (MP) de las gestaciones múltiples del Hospital Miguel Servet de Zaragoza (2000-2009). Método: Análisis, sobre un total de 44.401 recién nacidos (RN) >500 gramos, de 92 nacidos muertos ó fallecidos antes de los 28 días de vida procedentes de gestaciones múltiples. Los datos se recogieron en un formulario siguiendo las recomendaciones de la FIGO y la novena Clasificación Internacional de Enfermedades (CIE). Resultados: La MP ampliada global fue de 40,42/1000 nacidos. Analizada por el número de RN, la MP de los embarazos gemelares fue 34,65/1000 nacidos y la de las gestaciones triples 80,65/1000. La mortalidad fetal fue 11,86/1000 nacidos y la neonatal (MN) 28,56/1000 nacidos vivos. La MP estándar fue 14,06/1000. Esta MP constituye el 22,89 por ciento de la MP total del Hospital, y la MN de los múltiples el 35,33 por ciento de la mortalidad neonatal total. Un 97,83 por ciento fueron pretérminos; 72,83 por ciento fueron <1000 gramos y 88,05 por ciento <1500 gramos. La causa última fue inmadurez extrema, <1000 gramos (72,83 por ciento). Hubo un 18,48 por ciento de rotura prematura (RPM) de membranas, 17,39 por ciento de partos pretérminos espontáneos sin otra causa aparente, y 13,04 por ciento de malformaciones congénitas y cromosomopatías. Conclusión: La MP en múltiples está gravada por la prematuridad, y el bajo peso extremo. La MP de ambos gemelos ocurre en el bajo peso extremo (87,50 por ciento <1000 gramos), y sus causas más frecuentes son RPM (21,88 por ciento) con corioam-nionitis (12,50 por ciento) y el síndrome de transfusión feto-fetal (18,76 por ciento).

Objective: To evaluate Hospital Miguel Servet perinatal mortality (PM) in multiple pregnancies (2000-2009), valuing its evolution and distribution according to gestational age and birth weight. Maternal and fetal causes are analized. Methods: 44,401 newborns of >500 grams or 22 weeks gestational age, were studied. The total number of perinatal deaths in multiple pregnancies was 92 containing late neonatal deaths (to 28 days of live). The data for each case of perinatal mortality were recorded in a form following FIGO recommendations and the 9th International Classification Diseases. Results: Extended PM rate in multiple pregnancies was 40.42/1000 newborns, PM in twins was 34.65/1000, and in triplet births 80.65/1000. Fetal mortality was 11.86/1000 newborns and neonatal mortality 28.56/1000 live births. Standard PM was 14.06/1000 newborns. The MP of the multiple pregnancies was the 22.89 percent of total MP, and multiple pregnancies neonatal mortality 35.33 percent of total neonatal mortality. According to gestational age, 97.83 percent were preterm deliveries (90 newborns). Considering birth weights, 72.83 percent were extremely low birth weight (<1000 grams), and 88.05 percent were <1500 grams. Main cause of death was extreme immaturity (<1000 grams). Premature rupture of membranes (PROM) was presented in 18.48 percent, of the cases, spontaneous preterm labor without apparent cause in 17.39 percent, and congenital malformations and chromosomopaties (13.04 percent). Conclusions: PM in multiple pregnancies is encumbered by prematurity and extremely low birth weight. PM in both twins was associated with extremely low birth weight (87.50 percent < 1000 grams), and main causes of death were PROM (21.88 percent) with chorioamnionitis (12.50 percent), and twin-to-twin transfusion syndrome (18.76 percent).
