Este estudo objetivou identificar a prevalência dos diferentes tipos de aleitamento e sua relação com variáveis maternas no município de Conchas-SP, totalmente coberto pelo PSF. Foram obtidas informações sobre a alimentação atual das crianças menores de um ano que compareceram à primeira etapa da Campanha de Multivacinação de 2003. As associações foram submetidas ao teste do qui-quadrado, adotando-se 5% como nível de significância estatística. As prevalências do Aleitamento Materno Exclusivo (AME) e do Aleitamento Materno Predominante (AMP), em menores de 4 meses de vida, foram 25,4 e 44,4%, respectivamente, e 66,7% do total de crianças menores de um ano ainda eram amamentadas. A prevalência do AME em menores de 6 meses foi heterogênea, variando de 7,4 a 41,2%, conforme a equipe do PSF de procedência das crianças. Ter passado por dificuldades no início do aleitamento associou-se a menores prevalências de AME e Aleitamento Materno (AM). Esses resultados evidenciam situação distante da recomendada pela Organização Mundial de Saúde e aquela para a qual há evidências de máximo efeito protetor à saúde infantil, reafirmam a necessidade de apoio às mães no período puerperal precoce e demonstram a importância de diagnósticos desagregados por regiões para o planejamento de ações de promoção ao AM.

Both Epstein-Barr virus (EBV) types A and B are found in endemic Burkitt's lymphoma (BL) occurring in equatorial Africa. We studied 17 cases of Brazilian BL previously demonstrated to be EBV-positive to determine the EBV type as well as the presence of a characteristic 30 bp deletion within the 3' end of the latent membrane protein-1 (LMP-1) gene that may be important to the pathogenesis of several EBV-associated neoplasms. All case in which the age was known were children. We found type A EBV in 13 of 14 (93%) evaluable cases, and type B in one case. The LMP-1 deletion was found in 12 of 15 (80%) evaluable cases, including the one case of type B EBV, and a similar high prevalence (59%) of the deletion was detected in EBV-positive normal and reactive lymphoid tissues from individuals from the same geographic region. The high proportion of cases associated with type A EBV suggests that immunodeficiency is not an important factor in the pathogenesis of Brazilian BL, in contrast to endemic African BL. The presence of the LMP-1 deletion in a high prevalence in the normal population in this region is unexplained.

This paper presents a methodology for the placement and sizing evaluation of distributed generation (DG) in electric power systems. The candidate locations for DG placement are identified on the bases of Locational Marginal Prices (LMP's) obtained from an optimal power flow solution. The problem is formulated for two different objectives: social welfare maximization and profit maximization. For each DG unit an optimal placement is identified for each of the objectives.

Objective. The aim of this study was to verify the possibility of lactate minimum (LM) determination during a walking test and the validity of such LM protocol on predicting the maximal lactate steady-state (MLSS) intensity. Design. Eleven healthy subjects (24.2 ± 4.5 yr; 74.3 ± 7.7 kg; 176.9 ± 4.1 cm) performed LM tests on a treadmill, consisting of walking at 5.5 km h -1 and with 20-22% of inclination until voluntary exhaustion to induce metabolic acidosis. After 7 minutes of recovery the participants performed an incremental test starting at 7% incline with increments of 2% at each 3 minutes until exhaustion. A polynomial modeling approach (LMp) and a visual inspection (LMv) were used to identify the LM as the exercise intensity associated to the lowest [bLac] during the test. Participants also underwent to 24 constant intensity tests of 30 minutes to determine the MLSS intensity. Results. There were no differences among LMv (12.6 ± 1.7 %), LMp (13.1 ± 1.5 %), and MLSS (13.6 ± 2.1 %) and the Bland and Altman plots evidenced acceptable agreement between them. Conclusion. It was possible to identify the LM during walking tests with intensity imposed by treadmill inclination, and it seemed to be valid on identifying the exercise intensity associated to the MLSS.
