Perfil de mães e o desfecho do nascimento prematuro ou termo

The birth or delivery under 37 weeks of pregnancy is considered a global public health problem, since it is seen as one of the main risk factors for neonatal morbidity and mortality, particularly in the first week of life. This study had the objective of analyzing the profile of mothers of premature and full-term babies for the outcome of birth. This is an analytical-descriptive and cross-sectional study, with a sample of 109 mothers of all the premature babies and 135 mothers of the randomly selected full-term babies, by drawing, occurred in the period from April to September 2015, in a public maternity. Data were organized on Microsoft Excel 2013; subsequently, there was the analysis of the analytical-descriptive statistics, through Statistica 10, through which the frequencies, proportions, p values, with 5% significance level, through the Chi-square test, were identified. The project was submitted to the Research Ethics Committee of the Federal University of Rio Grande do Norte, receiving a favorable opinion (nº 1047431/2015). This study has enabled us to identify that the socioeconomic profile of mothers of premature and full-term babies showed, in both, low schooling level and low income. In addition, our data point out in the two groups, before and during pregnancy, a high prevalence of sedentariness; statistical significance for overweight and obesity before and during pregnancy, with 42,22% prevalence before pregnancy of mothers of premature babies and 48,62% of mothers of full-term babies; with high blood pressure during pregnancy in 32,11% of mothers of premature babies and 17,04% of mothers of full-term babies. Moreover, pregnancy was only planned in 33,33%, and also unwanted by 21,1% of mothers of premature babies, while 40,37% of mothers of full-term babies planned pregnancy and 17,78% had unwanted pregnancy. With respect to the aggravating factor “illicit drugs”, there was consumption during pregnancy on the part of 8,26% of mothers of premature babies. The most frequent complications were: vaginal bleeding (in 43,12% of mothers of premature babies and 20% of mothers of full-term babies); urinary infection (in 44,95% of mothers of premature babies and 40% of mothers of full-term babies); and stressful pregnancy (in 62,96% of mothers of premature babies and 47,41% of mothers of full-term babies). Accordingly, babies were born with health problems in 58,10% of premature births and there was healthy birth in 96,30% of full-term babies. Therefore, the profile of mothers with obesity and overweight, unwanted pregnancy, user of illegal drugs during pregnancy, stressful pregnancy and vaginal bleeding may be associated with the birth of premature baby as unfavorable and hazardous event for the child’s health.

Mães de neonatos pré-termo hospitalizados: avaliação do apoio social e da sintomatologia ansiogênica

Social support is an important factor throughout one s life, especially in times of crisis. Premature delivery can be considered a crisis, followed by neonatal hospitalization. This type of birth is associated with elevated anxiety, representing risks to maternal mental health and mother-infant relationship. This research aims to investigate whether a relationship exists between perceived social support and the expression of anxiety in mothers of premature, hospitalized newborns. This is a cross-sectional, correlational study, conducted during the period of April to October 2011, using a convenience sample. The sample consisted of seventy mothers with preterm, hospitalized newborns and seventy mothers of full-term newborns. The instruments used were the State-Trait Anxiety Inventory and the Social Support Scale. The results demonstrated a weak negative relationship between intensity-State Anxiety and emotional support as well as a negative relationship in intensity between low to moderate-Trait Anxiety, social support and its dimensions (material support, emotional, information, interaction positive social and emotional). These suggest that the better the perception of social support, the less severe anxiogenic symptoms will be, and the converse is also true. It is noteworthy, therefore, the importance of social support, as well as the importance of health professionals to be aware not only of the physical health of the newborn, but also the psychosocial aspects that pervade the context of preterm birth followed by hospitalization

O exame neurológico do recém-nascido pré-termo não complicado: avaliação pela escala de saint-anne dargassies, e screening pelas escalas de amiel-barrier-shnider modificada e prechtl ao termo

This study compared the evolution of posture, tone and neonatal reflexes in preterm infants without clinical or neurological complications before and after the age of term using the scale of Saint-Anne Dargassies. To reach the age of the term, was applied Scales Amiel-Barrier-Shnider changed and the Prechtl, traditionally used in the evaluation of term newborns, looking for possible changes to the term, while also evaluating the sensitivity of these scales. We studied 20 non-complicated preterm infants, both sexes aged 32-36 weeks, born in Januário Cicco Maternity School, from August 2006 to August 2007. Was applied to the scale of Saint-Anne Dargassies every two weeks until reach the term, and the range of Amiel-Barrier-Shnider changed and the Prechtl, after reaching 39 and 41 weeks. The evaluation result of articular angles was subjected to the test of Friedman ANOVA, significant differences between the three measurements of the scale of Saint-Anne Dargassies only for angles heel-to-ear to term. Neonatal reflexes changed in the period of prematurity were the cardinal points reflexes, Moro reflexes, cross extensions reflex and the automatic walking reflexes. The posture was the parameter which remained unchanged in the three scales. Considering a significance level of 5% by applying Cochran Q Test, it was found that the scale of Saint-Anne Dargassies is more sensitive to detect suspects. With this methodology and the results it was possible to prepare a manuscript: The neurological examination of non-complicated preterm newborns using the Sanit-Anne Dargssies Scale from birth to term: normal or altered? In which we describe that despite the good clinical condition, the RNP show changes in tone and neonatal reflexes. These data are important because though non-complicated RNP need further attention its maturation process, enabling us to detect and intervene early. With these results we can build a scale simplified neurological assessment made with items found most altered during the application of three scales. The development of this project has a multidisciplinary approach, because it involved Paediatric Neurologist, Physiotherapist and Neonatologist, as recommended by PPGCSA

Nascimento de um filho :o significado para o pai

Qualitative study on the meaning of a child s birth to the father. Its general purpose was to comprehend the significance the man attaches to his child s birth and its specific objectives were to identify the man s feelings with regard to his child s birth as well as to verify his attitude toward a child s birth. The study was founded on the theoretical reference system about the man in the gravid-puerperal cycle and the humanization of the assistance. The data were obtained through semistructured interview performed with men accompanying their children s birth whose wives were in the immediate puerperium. This stage occurred in two maternity hospitals in Natal-RN, both of which adopt the principle of safe notherhood in the attendance of women in the process of parturition. The material apprehended from the statements was treated in conformity with the content analysis method in the mode of thematic analysis according to Bardin. Three thematic categories emerged from this process: the father s attitude toward his child s birth, the father s feelings in respect of his child s birth, and the informations received by the father in the course of his child s birth. The speech content was analyzed in accordance with the principles of symbolic interactionism according to Blumer. The results showed that the husbands interact with their respective wives and respond with attitudes of care, help, support, and encouragement within the principles of humanization intermingled with feelings of happiness, restlessness, and suffering leading them to appraise and exalt their consorts. Besides, we verified that the father s attitudes and feelings in the delivery room in the light of symbolic interactionism tend to be influenced by the interaction between him and the attending professionals

Otimização Topológica com Termo-elasticidade Utilizando Elementos Tri3

This work proposes a formulation for optimization of 2D-structure layouts submitted to mechanic and thermal shipments and applied an h-adaptive filter process which conduced to computational low spend and high definition structural layouts. The main goal of the formulation is to minimize the structure mass submitted to an effective state of stress of von Mises, with stability and lateral restriction variants. A criterion of global measurement was used for intents a parametric condition of stress fields. To avoid singularity problems was considerate a release on the stress restriction. On the optimization was used a material approach where the homogenized constructive equation was function of the material relative density. The intermediary density effective properties were represented for a SIMP-type artificial model. The problem was simplified by use of the method of finite elements of Galerkin using triangles with linear Lagrangian basis. On the solution of the optimization problem, was applied the augmented Lagrangian Method, that consists on minimum problem sequence solution with box-type restrictions, resolved by a 2nd orderprojection method which uses the method of the quasi-Newton without memory, during the problem process solution. This process reduces computational expends showing be more effective and solid. The results materialize more refined layouts with accurate topologic and shape of structure definitions. On the other hand formulation of mass minimization with global stress criterion provides to modeling ready structural layouts, with violation of the criterion of homogeneous distributed stress
