Factores de riesgo presentes en prematuros menores de 1500 gramos de peso al nacer con displasia broncopulmonar atendidos en el Hospital Nacional Especializado de Maternidad 2011 – 2013.

La investigación se realizó con un universo de 220 pacientes, todos fueron niños prematuros menores de 1500 gramos nacidos entre el año 2011 al año 2013 y atendidos en la unidad de cuidados intensivos e intermedios neonatales del Hospital Nacional Especializado de Maternidad. El diagnóstico de la enfermedad se realizó principalmente basado en la necesidad de oxígeno suplementario por un mínimo de 28 días y según los criterios diagnósticos propuestos por el consenso del Instituto Nacional de la Salud de EE.UU (NICHD/NHLBI/ORD WORSHOP, 2000) (4) Se pudo evidenciar que los prematuros estudiados nacieron con mayor frecuencia a las 29 semanas de edad gestacional (calculadas por el método de Ballard modificado) y con un peso entre los 750 y los 1000 gramos. El tipo de displasia broncopulmonar más frecuentemente diagnosticado fue el de tipo leve y los factores de riesgo relacionados al desarrollo de la enfermedad fueron la presencia de infección materna al momento del parto y la infección posnatal, principalmente la infección asociada a la atención sanitaria (IAAS), la prematurez extrema y el extremado bajo peso al nacer; así como el uso prolongado de oxígeno por más de 55 días. El uso excesivo de líquidos endovenosos y la presencia de un conducto arterioso permeable ocurrieron con menos frecuencia.

ABLE-BODIED WOMANHOOD: DISABILITY AND CORPOREALLY EXCLUSIONARY NARRATIVES IN BLACK AND WHITE WOMEN’S RIGHTS DISCOURSES, 1832-1932

This project is a feminist disability rhetorical analysis of US black and white women’s rights movements from 1832-1932. Guided by Disability and Feminist Theory, it works to identify the presence and use of patterns of disability tropes in women’s rights discourses. From Lucretia Coffin Mott to Sojourner Truth, Elizabeth Cady Stanton to Mary Church Terrell, and Charlotte Perkins Gilman to Addie Hunton, this project interrogates the rhetorical work of dominant narratives and lesser known voices in women’s rights discourses. I argue that early black and white women’s rights advocates often utilized and repeated a disability rhetoric that relied on disability metaphor, narrative prosthesis, and corporeally exclusionary narratives in order to construct definitions of womanhood. Their insistence on cognitive ability as a marker of “fitness” and “ability” provided the foundation for rights arguments based on ableist assumptions of autonomy and citizenship. I also argue that this use of disability rhetoric relied on and furthered a pervasive ableist ideology present not only in many of these movements, but in US society. In the process, US black and white women’s rights discourses have continually elided women with disabilities from women’s rights discourses because their bodies (physically, cognitively, and/or psychologically) did not meet the ableist prerequisites set for claiming women’s rights during this time period.

Ribeira, técnica versus natureza: transformações em prol de um projeto de modernização (1860-1932)

The necessity of the insertion of the capital of Rio Grande do Norte in the world-wide commercial scene and its claim as the seat of political power, in ends of nineteenth and beginning of twentieth century, determined the direction of urban interventions undertaken by government to restructure the city. In that matter, there were several actions of improvements and embellishment in Natal, which had, as a starting point, the adequacy works of the port, located in the Ribeira quarter, with the aim of ending the physical isolation that reinforced its economic stagnation. Besides the problems faced in the opening bar of the Potengi River, and would complement the required improvements, other barriers demonstrate the tension established between the physic-geographic field and the man: the flooded and slope which connected Cidade Alta and Ribeira the first two quarters of the city.The execution of these works demanded knowledge whose domain and application it was for engineering. But, how the actions done for the engineers, in sense to transform natural areas into constructed spaces made possible the intentional conformation of the quarter of the Ribeira in a commercial and politician-administrative center, in the middle of the XIX century and beginning of the XX? Understand, therefore, the employment effects of technology on the physical-geographical Ribeira, is the objective of this work that uses theoretical and methodological procedures of Urban Environmental History, by analyzing the relationship between the environment and the man, mediated by knowledge and use of technologies. The documental research was used, as primary sources, the Messages of the Provincial Assembly Government that later became the Legislative Assembly of Rio Grande do Norte reports and articles on specialized publications, in addition to local newspapers. The work is structured in five chapters. First, some comments about Urban Environmental History (Chapter 1) supplemented with analysis of the conceptual construction of nature in the Contemporary Era and its application in the city (chapter 02), the following chapters (03 and 04) deal with the rise of engineers as a active group in the Brazilian government frameworks and their vision about the nature inside the urban environment and it is studied how the professional technicians dealt with the improvement work of the harbor and in the shock with the natural forces. Other works that would complement this "project" of modernization and had had natural obstacles to be removed the Ribeira flood and slope constitute the subject of the fifth chapter. Finally, some final considerations retake the initial discussions aiming an association between the technique and the nature as junction elements inside the process of constitution of a Modern Natal

Parto hospitalario en embarazadas de consulta externa del Hospital "San Sebastián" del Sigsig. Periodo Octubre de 2011-julio 2012.

Objetivo: Determinar el número de partos intrahospitalarios, en relación al primer control prenatal de las embarazadas de la consulta externa del Hospital “San Sebastián” del Sígsig. Material y métodos: Se realizó un estudio descriptivo en una muestra de 404 embarazadas, que acudieron a su primer control prenatal al Hospital “San Sebastián”, luego se determinó el porcentaje de gestantes que tuvieron el parto en este hospital. Resultados: La prevalencia del parto intrahospitalario en relación al primer control fue del 54.4%: 220 mujeres tuvieron el parto en el hospital. El resto 45.6% gestantes no acudieron al parto en esta institución. La media de edad fue de 25.7 años. La media de años de instrucción fue 7. La media de embarazos fue de 3. Conclusiones: El parto intrahospitalario en relación al primer control en esta zona es bajo: el 54.4% de gestantes, prácticamente solo la mitad, o una de cada dos embarazadas acude para el parto hospitalario; por lo tanto un gran número de gestantes está en riesgo de sufrir complicaciones, debido a que probablemente se den partos domiciliarios, atendidos por comadronas

Ten Year Study on Water Flushing Times and Water Quality in Southern Taylor Slough, Everglades National Park, FL

The purpose of this research was to investigate the effects of wetland restoration on the water balance, flushing time, and water chemistry of southern Taylor Slough, a major water way in Everglades National Park. Water balance and flushing time equations were calculated on a monthly time step from 2001 – 2011. Water chemistry of major ions and nutrients were analyzed and correlated with water flushing times. Results showed that evapotranspiration followed by water volume had the greatest influence on flushing time. The flushing times varied between 3 and 78 days, with longer times observed between October and December, and the shorter times between March and May. Ion concentrations at the coastal areas decreased with increased flushing times. Increased surface water inflow that resulted from restoration projects and water management changes were productive in the rainy season and should result in increased flushing times and decreased ion concentrations in Taylor Slough.

UM OLHAR SOBRE O NORDESTE: A CONTRIBUIÇÃO TÉCNICO-CIENTÍFICA DA REVISTA DA SOCIEDADE DE GEOGRAFIA DO RIO DE JANEIRO - BRASIL (1885-1932)

A criação e os esforços para manter os periódicos das associações profissionais e científicas foram fundamentais para consolidar o processo de formação da cultura técnica moderna no Brasil, a partir da segunda metade do século XIX. Ainda limitadas às dificuldades de circulação e a um reduzido corpo técnico, essas publicações configurariam uma arena pública que incorporou debates nacionais articulados desde então: necessidade de conhecimento e de integração do território, políticas centrais de circulação e comunicação, entre outros. Nesse contexto, a Revista da Sociedade de Geografia do Rio de Janeiro empenhava-se em desvelar um Brasil pouco conhecido. Compreender o papel desse periódico na construção de um pensamento próprio sobre a região Nordeste constitui o objetivo deste trabalho. A análise documental se faz a partir do material publicado entre 1885, ano da sua criação, e 1932, quando divulga artigo emblemático sobre o tema. Os estudos sobre os índices pluviométricos irregulares, a descrição da paisagem física e as crônicas de viagem à região proporcionaram novo olhar cujos contornos aprofundam a discussão acerca da conformação da “dimensão técnica das secas” e permitem o entendimento da formulação dos projetos nacionais (de transformação e controle do território) no âmbito técnico-científico, na virada para o século XX.

On the first tachinid fly (Diptera, Tachinidae) carrying Asclepiadoideae pollinaria in the Neotropical Region

On the first tachinid fly (Diptera, Tachinidae) carrying Asclepiadoideae pollinaria in the Neotropical Region. This paper reports the first Neotropical Tachinidae species possibly associated to pollination of Asclepiadoideae: a female of Euacaulona sumichrasti Townsend, 1908 (Diptera, Tachinidae, Phasiinae, Trichopodini) carrying pollinaria of Gonolobus parviflorus Decne., 1844 (Apocynaceae, Asclepiadoideae, Asclepiadeae: Gonolobinae) attached to its proboscis. The fly specimen was collected in Paraguay, Departamento Canindeyú. The pollinarium is illustrated and described herein. This represents the first anthophilous record to G. parviflorus and to the genus.

Medidas murinométricas e eficiência alimentar em ratos provenientes de ninhadas reduzidas na lactação e submetidos ou não ao exercício de natação

INTRODUÇÃO: Excesso de alimentação no início da vida pode modificar persistentemente consumo e peso corporal. Adoção de exercício físico é uma estratégia útil para evitar excessivo ganho de peso. OBJETIVO: Avaliar o crescimento corporal e a eficiência alimentar em ratos provenientes de ninhada reduzida no aleitamento. MÉTODOS: Ao terceiro dia de vida, ninhadas foram formadas com quatro (GN4) ou 10 animais (GN10), (n = 25). Ao desmame, ratos machos Wistar permaneceram em gaiolas individuais, e, aos 60 (± 2) dias foram subdivididos em sedentários (SED) e exercitados (NAT), formando quatro grupos: GN4SED, GN10SED, GN4-NAT e GN10NAT. Avaliou-se o peso, ganho de peso e taxa específica de ganho de peso, gordura epididimal, índices de massa corporal e Lee, consumo e eficiência alimentar, glicemia e lactemia. RESULTADOS: Aos 21 dias, o GN4 apresentava peso corporal 52% acima do GN10 (P = 0,001). Contudo, aos 30 e 60 dias os pesos não diferiram. Ao final do período, GN10NAT demonstrou menor peso (356,82 ± 23,04) que GN10SED (409,28 ± 17,30). Mas GN4NAT possuía maior peso (417,85 ± 37,91) que GN4SED (413,69 ± 57,45) e GN10NAT. O GN4 exibiu elevada taxa de ganho de peso na lactação, mas, redução da mesma pós-desmame. Independente do tamanho da ninhada, a taxa de ganho de peso reduz com o aumento da idade. Ao final do período, glicemia, gordura epididimal total e relativa, e os índices de Lee e IMC não diferiram entre os grupos. Os valores de lactato antes e após o exercício condizem com esforço de intensidade moderada. Na periadolescência, GN4 apresentou menor ingestão de alimentos, mas sem diferenças na vida adulta. CONCLUSÃO: A redução da ninhada no aleitamento não alterou o peso corporal ou ingestão alimentar persistentemente. Entretanto, o protocolo de natação foi eficaz em reduzir o ganho de peso em animais controles, mas não naqueles de ninhada reduzida.

Morphology and reproduction of Mesophyllum erubescens (Foslie) Me. Lemoine (Corallinales, Rhodophyta) from Southern Brazil

The genus Mesophyllum Me. Lemoine includes around 147 species, of which only three have been referred to the Brazilian coast. Mesophyllum erubescens was originally described from Fernando de Noronha Archipelago, Brazil (type locality). Here we present the first detailed description of M. erubescens based on Brazilian material. Samplings were made through scuba diving at the Biological Marine Reserve of Arvoredo Island, Santa Catarina. The relations of M. erubescens with other similar species, especially from the American Atlantic studied by W.R. Taylor are discussed.

Characterization of aqueous silver nitrate solutions for leakage tests

OBJECTIVE: To determine the pH over a period of 168 h and the ionic silver content in various concentrations and post-preparation times of aqueous silver nitrate solutions. Also, the possible effects of these factors on microleakage test in adhesive/resin restorations in primary and permanent teeth were evaluated. MATERIAL AND METHODS: A digital pHmeter was used for measuring the pH of the solutions prepared with three types of water (purified, deionized or distilled) and three brands of silver nitrate salt (Merck, Synth or Cennabras) at 0, 1, 2, 24, 48, 72, 96 and 168 h after preparation, and storage in transparent or dark bottles. Ionic silver was assayed according to the post-preparation times (2, 24, 48, 72, 96, 168 h) and concentrations (1, 5, 25, 50%) of solutions by atomic emission spectrometry. For each sample of each condition, three readings were obtained for calculating the mean value. Class V cavities were prepared with enamel margins on primary and permanent teeth and restored with the adhesive systems OptiBond FL or OptiBond SOLO Plus SE and the composite resin Filtek Z-250. After nail polish coverage, the permanent teeth were immersed in 25% or 50% AgNO3 solution and the primary teeth in 5% or 50% AgNO3 solutions for microleakage evaluation. ANOVA and the Tukey's test were used for data analyses (α=5%). RESULTS: The mean pH of the solutions ranged from neutral to alkaline (7.9±2.2 to 11.8±0.9). Mean ionic silver content differed depending on the concentration of the solution (4.75±0.5 to 293±15.3 ppm). In the microleakage test, significant difference was only observed for the adhesive system factor (p=0.000). CONCLUSIONS: Under the tested experimental conditions and based on the obtained results, it may be concluded that the aqueous AgNO3 solutions: have neutral/alkaline pH and service life of up to 168 h; the level of ionic silver is proportional to the concentration of the solution; even at 5% concentration, the solutions were capable of indicating loss of marginal seal in the composite restorations; the 3-step conventional adhesive system had better performance regarding microleakage in enamel on primary and permanent teeth.

Natural antioxidant from yerba maté (Ilex paraguariensis St. Hil.) prevents hamburger peroxidation

The aim of this study was to evaluate whether yerba maté alcoholic extracts at very low concentrations (0.01 and 0.1%), prevent/retard lipid peroxidation in beef hamburgers without impairing sensory acceptability. For this TBARs and hexanal levels, fatty acid profile and cholesterol oxides were evaluated as oxidation parameters in beef hamburgers during 90 days' storage. The addition of 0.01% yerba maté ethanolic extracts proved inefficient in restraining the lipid peroxidation while the addition of 0.1% resulted in efficient antioxidant activity. Sensory evaluation of hamburger containing 0.1% yerba maté ethanolic extracts showed good acceptability. Yerba maté ethanolic extracts could entirely or partially replace the phenolic synthetic antioxidants in beef hamburgers only when used at above legally allowed concentrations for antioxidant additives (0.01%).

Change and Aging Senescence as an Adaptation

Understanding why we age is a long-lived open problem in evolutionary biology. Aging is prejudicial to the individual, and evolutionary forces should prevent it, but many species show signs of senescence as individuals age. Here, I will propose a model for aging based on assumptions that are compatible with evolutionary theory: i) competition is between individuals; ii) there is some degree of locality, so quite often competition will be between parents and their progeny; iii) optimal conditions are not stationary, and mutation helps each species to keep competitive. When conditions change, a senescent species can drive immortal competitors to extinction. This counter-intuitive result arises from the pruning caused by the death of elder individuals. When there is change and mutation, each generation is slightly better adapted to the new conditions, but some older individuals survive by chance. Senescence can eliminate those from the genetic pool. Even though individual selection forces can sometimes win over group selection ones, it is not exactly the individual that is selected but its lineage. While senescence damages the individuals and has an evolutionary cost, it has a benefit of its own. It allows each lineage to adapt faster to changing conditions. We age because the world changes.
