Effect of body temperature of heavy broiler breeders on resistance to heat of their progeny

This trial aimed at studying the effects of the body temperature (BT) of heavy broiler breeders (HBB) on the productive parameters and the resistance to heat of the broilers of their progeny. The experiment was done on two phases: (1) measurements on breeders were done in the commercial hatchery, whereas (2) the tests on broilers were done in the poultry unit of UCV. In phase 1, 280 HBB of line L1 (Ross x Ross) and 280 HBB of line L2 (Hybro) were tested for their rectal body temperature (BT) and level of hyperventilation (LH) during periods of high ambient temperature. The animals were split into two groups: higher BT (HBT, 41.26±0.01°C) and lower BT (LBT, 40.9±0.08°C). Egg production, fertility and hatchability were recorded. A total of 400 chicks (100 of lower of higher parent BT for both lines) were raised in same environmental conditions, and tested for BT, LH and productive parameters. Egg production did not differ between breeders HBT or LBT. Fertility was significantly higher in L2 (98.5±0.08) than in L1 (96.02±0.61). In phase 2 weight gain, feed intake and feed conversion did not differ between animals issued from lower or higher BT parents. At day 36 during a heat challenge (TA=37°C), the BT of animals from L2 issued from parents of higher BT was higher (43.2±0.092 vs 42.7 ± 0.08, p<0.01) whereas this difference was not significant in line L1. Mortality during heat challenge was also 40% higher for these animals. These results suggest than there can be a heritability of BT characteristics, which could have an effect on the resistance of broilers to heat stress. (Résumé d'auteur

A pauta da política externa brasileira para a América Latina no foro de São Paulo durante os governos Lula (2003-2010), e sua influência sobre os processos decisórios em política externa no Brasil

O I Encontro Internacional de Política Externa Latino-Americana, aconteceu nos dias 14, 15 e 16 de setembro de 2015 em Foz do Iguaçu/PR, a partir de uma iniciativa do Núcleo de Pesquisa de Política Externa Latino-Americana (NUPELA), formado por professores e estudantes da Universidade Federal da Integração Latino-Americana (UNILA).O projeto de trabalho ora apresentado objetiva, analisar e descrever as propostas de Política Externa Brasileira para a América Latina defendidas pelo PT no Foro de São Paulo durante os anos do governo Lula (2003-2010) a fim de averiguar se houve ou não influência de tais propostas sobre as agenda da política Externa Brasileira durante os governos de Lula da Silva. Faz-se necessário, para tanto, um estudo cuidadoso acerca dos processos decisórios em Política Externa, que por conseguinte envolve a análise do MRE/Itamaraty. Busca-se apreender as linhas gerais das propostas de política externa do PT nos encontros anuais do Foro, que reúne partidos declarados como de esquerda na América Latina.Núcleo de Pesquisa de Política Externa Latino-Americana (NUPELA); Universidade Federal da Integração Latino-Americana (UNILA

Survival Probability in Patients with Sickle Cell Anemia Using the Competitive Risk Statistical Model.

The clinical picture of patients with sickle cell anemia (SCA) is associated with several complications some of which could be fatal. The objective of this study is to analyze the causes of death and the effect of sex and age on survival of Brazilian patients with SCA. Data of patients with SCA who were seen and followed at HEMORIO for 15 years were retrospectively collected and analyzed. Statistical modeling was performed using survival analysis in the presence of competing risks estimating the covariate effects on a sub-distribution hazard function. Eight models were implemented, one for each cause of death. The cause-specific cumulative incidence function was also estimated. Males were most vulnerable for death from chronic organ damage (p = 0.0005) while females were most vulnerable for infection (p=0.03). Age was significantly associated (p ≤ 0.05) with death due to acute chest syndrome (ACS), infection, and death during crisis. The lower survival was related to death from infection, followed by death due to ACS. The independent variables age and sex were significantly associated with ACS, infection, chronic organ damage and death during crisis. These data could help Brazilian authorities strengthen public policies to protect this vulnerable population
