INTERVENÇÕES LÚDICAS COM MÃES DE RECÉM-NASCIDOS PRÉ-TERMO HOSPITALIZADOS

Esta pesquisa investiga a influência de intervenções lúdicas na diminuição da ansiedade materna com mães de recém-nascidos pré-termo hospitalizados, em um hospital universitário da Grande São Paulo. São estudadas 30 mães que tiveram parto prematuro, com faixa etária entre 16 e 40 anos e escolaridade até 2º grau, por meio de estudo avaliativo-interventivo-evolutivo. Inicia-se por uma entrevista psicológica semidirigida, com o objetivo de traçar o histórico gestacional, seguida de aplicação da Escala de Ansiedade, Depressão e Irritabilidade IDA, visando identificar o nível de ansiedade materna e do Inventário de Percepção Neonatal IPN-I para verificar a expectativa das mães em relação ao comportamento de choro, alimento e vômito de seus bebês pré-termo. A seguir são efetuadas intervenções grupais lúdicas em 16 encontros, um a cada semana, de 60 minutos, segundo modelo piagetiano, que estimula processos afetivosemocionais e cognitivos. Os dados relativos ao histórico gestacional revelam que 75% das mães encontram-se na segunda gestação e já sofreram aborto ou óbito fetal; têm ida de gestacional média de 31 semanas; peso médio do bebê ao nascer de 1.640g. e tempo de internação médio de 39,93 dias. Na análise do IDA em relação à ansiedade, 75% delas apresentam escore de alta intensidade (11,25), também alto quanto à depressão (10); o escore médio (3,73) da irritabilidade exteriorizada acompanha o da irritabilidade interiorizada (3,23). A correlação entre depressão e ansiedade indica que uma reação emocional segue a outra, não havendo diferença significativa importante entre ambas (p=0,306). O IPN-I comprova que as 30 mães têm expectativas em relação ao próprio filho similares aos bebês em geral, mostrando escores médios de 8,63 e 9,20, respectivamente, confirmados pelo escore 10,0 apontado em 75% da amostra, o que configura uma alta expectativa quanto aos aspectos de sono, alimentação e vômito dos bebês. A análise qualitativa revela que a criação de grupos lúdicos mostra-se favorável, com alta adesão e motivação das mães, favorecendo a diminuição da ansiedade, a adaptação à realidade vivida e a interação mãe-bebê de forma saudável durante a internação. O estudo apresenta a trajetória interventiva de três casos emblemáticos de diferentes níveis de ansiedade, ilustrando esta evolução. Estes dados sugerem que esta modalidade de intervenção caracterize-se como uma medida de prevenção, promoção e preservação da saúde física e psíquica da mãe e do recémnascido prematuro, com repercussões na família e na sociedade.(AU)

Some Applications of Simons’ Inequality

We survey several applications of Simons’ inequality and state related open problems. We show that if a Banach space X has a strongly sub-differentiable norm, then every bounded weakly closed subset of X is an intersection of finite union of balls.

Avaliação da concentração de vitamina A materna e de neonatos prematuros e a termo

Vitamin A is an essential nutrient for many physiological processes such as growth and development, so that their adequate nutritional state is essential during pregnancy and lactation. Lactating women and children in breastfeeding are considered risk groups for vitamin A deficiency and some factors may increase the risk of vitamin A deficiency, such as prematurity. The aim of this work was to evaluate the vitamin A concentration in preterm and term lactating women and newborns by determination of retinol in maternal serum, umbilical cord serum and breast milk collected until 72 hours postpartum. 182 mothers were recruited and divided into preterm group (GPT; n = 118) and term group (GT, n = 64). In preterm group were also analyzed transition milk (7th-15th day; n = 68) and mature milk (30th-55th day; n = 46) samples. Retinol was analyzed by high-performance liquid chromatography (HPLC). Maternal retinol concentration in serum was 48.6 ± 12.3 µg/dL in GPT and 42.8 ± 16.3 µg/dL in the GT (p <0.01). Cord serum retinol was 20.4 ± 7.4 µg/dL in GPT and 23.2 ± 7.6 µg/dL in GT (p> 0.05). Among newborns, 43% of premature and 36% of term had low levels of serum retinol in umbilical cord (<20 µg/dL). In colostrum, the retinol in preterm and term groups had an average of 100.8 ± 49.0 µg/dL and 127.5 ± 65.1 µg/dL, respectively (p <0.05). The retinol average in preterm milk increased to 112.5 ± 49.7 µg/dL in transition phase and decreased to 57.2 ± 23.4 µg/dL in mature milk, differing significantly in all stages (p <0.05). When comparing with the recommendation of vitamin A intake (400 µg/day) GT colostrum reached the recommendation for infants, but in GPT the recommendation was not achieved at any stage. Mothers of premature infants had higher serum retinol than mothers at term; however, this was not reflected in serum retinol of umbilical cord, since premature had lower concentration of retinol. Such condition can be explained due to lower maternal physiological hemodilution and placental transfer of retinol to the fetus during preterm gestation. Comparison of retinol in colostrum showed lower concentrations in GPT; however the transition phase there was a significant increase of retinol content released by the mammary gland of preterm mothers. This situation highlights a specific physiological adaptation of prematurity, likely to more contribute to formation of hepatic reserves of retinol in premature infants.

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.

Caracterização termo-mecânica de interconectores metálicos recobertos com filmes de LaCrO3

The cells unitaria of the solid oxide fuel cell are separated by means of interconnects, which serve as electrical contact between the cells. Lanthanum Chromite (LaCrO3) has been the most common material used as interconnect in solid oxide fuel cells. Reducing the operating temperature around 800 º C of cells to solid oxide fuel make possibilite the use of metallic interconnects as an alternative to ceramic LaCrO3. Metallic interconnects have advantages over ceramic interconnects such as high thermal conductivity, electricity, good ductility, low cost, good physical and mechanical properties. In this work evaluate the thermo-mechanical properties of the metallic substrate and coated metallic substrate with the ceramic LaCrO3 film via spray-pyrolysis, in order to demonstrate the feasibility of using this material as a component of a fuel cell solid oxide. The materials were characterized by X-ray diffraction, oxidation behavior, mechanical strength, optical microscopy (OM) and scanning electron microscopy (SEM). The X-ray diffraction proved the formation phase of the LaCrO3 on the metallic substrate and the identification of the phases formed after the oxidative test and mechanical strength at high temperature. The oxidation behavior showed the increased oxidation resistance of the coated metallic substrate. It was noted that the mechanical resistance to bending of the coated metallic substrate only increases at room temperature. The optical microscopy (OM) has provided an assessment of both the metallic substrate and the LaCrO3 film deposited on the metal substrate that, in comparison with the micrographs obtained from SEM. The SEM one proved the formation of Cr2O3 layer on the metallic substrate and stability of LaCrO3 film after oxidative test, it can also observe the displacement of the ceramic LaCrO3 film after of mechanical testing and mapping of the main elements as chromium, manganese, oxygen, lanthanum in samples after the thermo-mechanical tests.

Estudio del efecto del procesamiento termo mecánico sobre los parámetros de formabilidad en aceros IF para aplicaciones automotrices

En el presente trabajo de investigación se analizó un acero libre de elementos intersticiales estabilizado con Titanio o mejor conocido como acero IF (por sus siglas en inglés Interstitial Free), denominado por la empresa EDDS (Extra Deep Drawing Steel) el cual se utiliza en partes exteriores de los vehículos en donde se requiere que la lámina a estampar cumpla con propiedades muy altas de ductilidad y baja resistencia. Se obtuvo acero IF en sus distintas etapas de procesamiento termo mecánico comenzando por material laminado en caliente, material laminado en frio y por ultimo material recocido y galvanizado en planta, esto con el objetivo de caracterizar y evaluar las propiedades mecánicas de cada etapa. De la etapa final del acero (recocido y galvanizado de planta) se obtuvieron los parámetros de formabilidad (n y R) mediante una prueba de tensión para poder establecer las condiciones a superar con las experimentaciones. El objetivo principal en el laboratorio fue el mejorar, mediante diferentes variables de recocido (tiempo y temperatura) en los tratamientos térmicos, los parámetros n= 0.23 y R=1.56 producidos en planta, y lograr obtener mediante nuevos tratamientos térmicos valores de R> 1.56 al igual que valores de n>0.23. Para simular las temperaturas con tiempos cortos de recocido se implementó un calentamiento por inducción en la bobina del laboratorio. Se pudieron realizar solo 2 pruebas debido al material disponible para este experimento. Ambos experimentos resultaron en una notable mejoría del valor de Lankford R (utilizado como un indicador en la formabilidad de hojas de acero), así como del exponente de endurecimiento por deformación (n), y se logró mantener un poco por encima sus propiedades de esfuerzo de cedencia, esfuerzo último y por ciento de elongación a las obtenidas por el proceso de recocido realizado en planta.
