The aim of this research was to evaluate previous serum screening for hepatitis B (total anti-HBc) among blood donation candidates, verifying the link between the variables: gender, age, degree of education and native-born. A transverse study with retrospective data carried out on a target population, blood donation candidates from districts of the interior of Acre State, who came to the Acre Hematology and Hemoterapy Center during the period January to December, 2002. The research indicated reactivity in 54.8% of the total anti-HBc among the 673 candidates included. Greater reactivity of total anti-HBc was observed among males, older candidates and those with lower education levels (p<0.005). Previous serum screening for hepatitis B among blood donation candidates is a viable alternative, since it reduces cost and increases transfusional safety. Attracting female donors, youths and those who have higher education levels, would signify potential blood donors for HEMOACRE.

A study on infant mortality in Rio Branco Acre-Brasil was done with the live childbirths of 1997. with residing mothers whose childbirths took place within the city's limits. The main goals o f the research were to cover the cohort o f living childbirths. according to the constant variables of the living childbirths declaration. as well as the drawing up of the minor"s deaths as of one year old from this cohort. according to sex. death age and main causes o f death. Further studies. from a statistic point of view. covered wich of the constant variables of the declaration would be acting as a risk factor to infant mortality. Conceming living childbirths, a high rate of hospital deliveries was observed, about 99.00%. with 73.26% for natural birth rate and a supremacy of male births over female births. Low weight percentage at birth was around 7.50% on total births. Concemig deaths. a higher figure among male children was noted. Most of them having ocurred in the precocious neonatal period. reaching 53.95% on total deaths. Among the basic causes selected, perinatal causes predominated among the neonatal deaths. followed by congenital anomalies and by natural infections: for the postneonatal period, the infections prevailed. The study of risks factors showed associations statistically significative between death and weight at birth, pregnancy duration. type of pregnancy, condition of pregnancy, number of prenatal visits. mathemal schooling and sex. Associations with type of delivery, parity and mathemal age were not statistically significative. Índice 1-Histórico do registro dos fatos vitais. 2-Importância das estatísticas de mortalidade.
