Abstract: Objective: to describe the experience as nursing students and scholars in two extension projects at the Family Health Program in a community in Vila Isabel /RJ from March/2008 to February/2009. Methodology: activities involved from home visits to the consultations. Results: the performance on these projects made it possible to separate the beneficial experiences in the interdisciplinarity of obstacles in its implementation, such as conflicts in the team to have consensus on actions, lack of organization and the different views of the health-illness process. In addition, most assiduous scholars were the most charged and the relations of hierarchy, many times, influenced the opinions expressed. Observed in nursing education the difficulty in deconstructing the barriers between different disciplines. It was found that these problems range from training and experience of teachers, to the resistance of the models introduced in stages. Conclusion: we want to show how health professionals need to learn, since the graduation, to respect the knowledge of others and to face problems in relations not as obstacles but as challenges that can and should be overcome by new generations.

Abstract: dolabelladienotriol is a product extracted from the brown marine alga dictyota pfaffii from brazil that has been shown to have antiviral activity and low cytotoxicity. our studies have evaluated the acute toxicity of dolabelladienotriol in balb/c mice for ten days after administration of a single dose. among the parameters considered were behavior, weight, biochemical and histological analyses of blood samples taken at three different times (bs.0, bs.1 and bs.2) and optical microscopic examination of organs like liver, kidney, stomach and small intestine. mice deaths were not observed at any dose during the ten day period. there were some changes in the biochemical analysis results for urea nitrogen (bun) and alanine aminotransferase (alt), but the changes were not significantly different from the reference levels of the animals before administration of the substance. histological analyses of tissues were very similar for all animals. the alterations in liver and kidney tissues did not affect the animals′ behavior at any concentration, not even at 50 mg/kg, where the most significant changes in tissues were seen. this study indicates that dolabelladienotriol has low toxicity in administered dose range.

Abstract: objective. to assess the validity of recommendations for use of the 85th and 95th percentiles of body mass index (bmi) of the population in the united states of america as a screening tool to assess overweight/obesity in adolescents. methods. we investigated the relation between bmi and percent body fat in 1 540 adolescents (717 males and 823 females) aged 10 to 17.9 years old from a private high school in niterói, a city in the state of rio de janeiro, brazil. we used bioelectric impedance, with the appropriate equations for adolescents, to estimate percent body fat, which served as the gold standard (30% for girls and 25% for boys) to calculate the sensitivity and specificity of the 85th and 95th percentiles of the united states and brazilian distribution curves of bmi. results. sensitivity and specificity were high (above 80%) for the niterói boys, except for the 85th percentile of the brazilian curve (specificity = 61.8%) and for the 95th percentile of the united states curve (sensitivity = 55.4%). for the niterói girls, the 85th- and 95th-percentile bmi cutoff points, from both the united states and brazilian curves, showed low sensitivity, and that sensitivity decreased with age. specificity was high for the girls, and much higher than it was for the boys. conclusions. these data suggest that using bmi to screen for overweight/obesity in adolescents can generate a high percentage of false-positives for niterói boys and an even higher percentage of false-negatives for niterói girls. a more universal approach to using anthropometric measures to screen for overweight/obesity should be developed, preferably linked to stages of maturation.

For the Niterói girls, the 85th- and 95th-percentile BMI cutoff points, from both the United States and Brazilian curves, showed low sensitivity, and that sensitivity decreased with age. Specificity was high for the girls, and much higher than it was for the boys. Conclusions. These data suggest that using BMI to screen for overweight/obesity in adolescents can generate a high percentage of false-positives for Niterói boys and an even higher percentage of false-negatives for Niterói girls.

Abstract: A hundred Pseudomonas aeruginosa strains from several clinical specimens from five hospitals in Sao Luís-MA were evaluated for biofilm production, prevalence of the gene algD, adhesion to HEp-2 cells and antimicrobial susceptibility. The most affected clinical specimens and hospital sectors were also evaluated. Most isolates were obtained from the tracheal aspirate (21.0%) and the most affected hospital sector was the ICU (43.0%). The antibiotics with the highest sensitivity rate were amikacin, piperacillin/tazobactam, fluoroquinolones, gentamicin and meropenem and the ones with the highest resistance rate were aztreonam, ceftazidime and cefepime. All samples were sensitive to polymyxin B. In relation to the expression of the gene for ESBL, 50.0% (17/34) of the multiresistant strains showed the enzyme TEM. Most strains showed high hydrophobicity and 96% of the isolates produced biofilm on a polystyrene microplate, 52% were capsule producers, 19% showed mannose-sensitive fimbriae and 39% expressed the gene algD. We observed adhesion to HEp-2 cells and to the coverslip. These factors may be reported in the pathogenesis of this bacterium, what represents a potential risk for colonization of medical devices which favor the establishment of chronic nosocomial infections.

Abstract:

The objectives of this study were to evaluate the fermentative and bromatological characteristics of Piata palisadegrass that was ensiled with energetic brans and to assess the costs of different additive levels. This experiment was conducted at the Goiano Federal Institute on the Rio Verde campus in Goiás State, Brazil. The experimental design was entirely random with four replications in a 4 × 5 factorial scheme that included four energetic brans (millet, maize, sorghum and wheat) and five levels (0%, 8%, 16%, 24% and 32%). The energetic brans can be considered as a good source of additives for Piata palisadegrass ensiling, which improves the qualitative and nutritional fermentative characteristics of the silage. The maize and wheat brans were the most efficient for improving the fermentative characteristics of the silage. However, millet bran was the most efficient for improving the bromatological characteristics. In addition, the wheat bran had the greatest influence on the final production cost and the sorghum and millet brans were the most economically feasible. Overall, the addition of 24% bran is recommended due to its beneficial impact on silage quality and the average final production cost of the silage.

Abstract: a study of infant mortality and its components was carried out in a cohort of live born children from hospitals of ribeir?o preto, city of s?o paulo, brazil, whose mothers were interviewed shortly after deliverance. mortality was associated to social classes and birthweight. the uneven distribution of mortality showed that social classes acted as distinct populations and that birthweight was not the only cause of this unballance. lower social classes were associated with higher low birthweight rates and mortality coefficients. the study of infant mortality without taking into account the social differences may show coefficients that underestimate the magnitude of the problem among the poorest population segments.
