Análise histomorfométrica do músculo cardíaco de ratos recém natos gerados por matrizes submetidas ao tabagismo passivo associado ao exercício

Maternal smoking during pregnancy causes heart changes, impaired fetal growth, spontaneous abortion and low birth weight. Even in pregnant women exposed to cigarette smoke these changes can be observed. But the exercise is to answer the increased fetal weight, besides the improvement of cardiorespiratory fitness of the pregnant and the fetus. The objective of this study was to analyze the ventricular muscle of young rats subjected to passive smoking associated with aquatic exercise. For the experiments used 24 female rats were divided into: GC (control), GE (exercise protocol in the water), GF(exposed to cigarette smoke) and GEF (exercise protocol on water and exposed to cigarette smoke). On the same day was held the 1st session of the experimental phase of the protocol of exposure to cigarette smoke, which consisted of 30 minutes twice a day, six days a week for three weeks, followed by the first session of the swimming program...

Gravidez na adolescência: determinante para prematuridade e baixo peso

Prematurity and low birth weight are public health problems. This paper aims to relate the occurrence of premature labors and low birth weight with adolescent pregnancy. We performed a literature review about the socioeconomic and cultural conditions of adolescent pregnancy and perinatal results. Through bibliographical data, we identified observational and systematic review articles that deal with the subject. The literature analysis permits us to conclude that adolescent pregnancies as well as the socioeconomic and cultural environment in which the young mother is inserted are associated with the increased frequency of prematures and low birth weight babies. The development and the implementation of effective public policies directed to that population are necessary to a better approach of the problem.

Influência das Alterações Hemodinâmicas Maternas sobre o Desenvolvimento Fetal

Objetivo: avaliar as alterações hemodinâmicas e estruturais cardíacas maternas nos três trimestres da gestação e relacioná-las com a classificação do recém-nascido, de acordo com o peso/idade gestacional. Métodos: foi realizada avaliação ecocardiográfica em 22 gestantes, sem patologias, para estudo do débito cardíaco, pressão arterial média, diâmetro do átrio esquerdo e resistência periférica, em três períodos da gestação: antes da 12ª , na 26ª e na 36ª semanas de gestação. Dezessete gestantes deram à luz recém-nascidos com peso adequado, quatro, recém-nascidos pequenos, e uma gestante, recém-nascido grande para a idade gestacional. Resultados: nas mães que deram à luz recém-nascidos pequenos para a idade gestacional, o débito cardíaco e o diâmetro do átrio esquerdo mantiveram-se inalterados, com tendência de elevação da pressão arterial média e aumento de 28% da resistência periférica, durante a gestação. As mães que deram à luz recém-nascidos adequados para idade gestacional tiveram aumento médio do débito cardíaco de 19% entre o primeiro e segundo trimestres e de 8% entre o segundo e terceiro trimestres da gestação. O diâmetro do átrio esquerdo elevou-se próximo de 9% durante a gestação, com manutenção da pressão arterial média e tendência de queda da resistência periférica. Conclusões: os resultados obtidos nesse trabalho suportam a associação entre adaptação hemodinâmica e peso do RN

Is urine interleukin-8 level a reliable laboratory test for diagnosing late onset sepsis in premature infants?

The present study is aimed to determine serum and urine interleukin-8 (IL-8) levels in premature infants with late onset sepsis (LOS) and to evaluate if urine IL-8 is a useful test for LOS diagnosis. Fifty-six premature infants admitted to the NICU over 1 year had serum and urine IL-8 determined by ELISA. They were divided into three groups: I definite sepsis, II probable sepsis and III non-infected. Results were expressed as mean or median. Differences between groups were assessed by ANOVA, Kruskal-Wallis ANOVA and Dunns Method. Sensitivity, specificity and positive and negative predictive values were calculated and a receiver operator characteristic curve was constructed to determine serum and urine IL-8 accuracy. There were no differences between groups for birth weight, and gestational and post-natal age. Median serum and urine IL-8 levels were significantly higher in GI and GII: 929 x 906 x 625pg/ml; P=0.024, and 249 x 189 x 42pg/mgCr; P< 0.001. Optimal cut-off point was 625pg/ml for serum IL-8 with 69 sensitivity and 75pg/mgCr for urine IL-8 with 92 sensitivity. IL-8 can be determined in urine from premature infants with LOS and is an accurate and feasible diagnosis method.

Genetic and non-genetic effects on calf vigor at birth and preweaning mortality in nellore calves

The objective of the present study was to evaluate the genetic and non-genetic effects that influencevigor at birth and preweaning mortality in Nellore calves. A total of 11,727 records of births that occurred between 1978 and 2006, offspring of 363 sires, were analyzed. Poor calf vigor at birth (VB) and preweaning mortality divided into stillbirth (SB), early mortality (EM) and total mortality (TM) were analyzed as binary variables. Generalized linear models were used for the evaluation of non-genetic effects and generalized linear mixed models for genetic effects (sire and animal models). The incidences were 4.75% for VB, 2.66% for SB, 5.28% for EM, and 7.99% for TM. Birth weight was the effect that most influenced the traits studied. Calves weighing less than 22kg(females) and less than 24kg (males) were at a higher risk of low vigor and preweaning mortality. Preweaning mortality was higher among calves born from cows aged .3 and .11 years at calving compared with cows aged 7 to 10 years. Male calves presented less vigor and higher preweaning mortality than female calves. Selection for postweaning weight did not influence preweaning mortality. The heritability estimates ranged between 0.01 and 0.09 for VB, 0.00 and 0.27 for SB, 0.03 and 0.17 for EM and 0.02 and 0.10 for TM. Stillbirth should be included as a selection criterion in breeding programs of Nellore cattle, alone or as part of a selection index, aiming to reduce preweaning mortality. © 2013 Sociedade Brasileira de Zootecnia.
