Evidências do cuidado de enfermagem para o conforto/bem-estar dos clientes com dermatoses imunobolhosas: ensaio clínico

O contato com pessoas acometidas por dermatoses imunobolhosas (DI) é impactante devido ao visível sofrimento causado pelo desconforto/mal-estar e comprometimento da autoimagem. Trata-se de um grupo de doenças de evolução crônica cuja manifestação primária e fundamental consiste no desenvolvimento de bolhas e menos frequentemente de vesículas na pele e/ou mucosas. O desafio de cuidar desta clientela justifica-se pelo caráter desfigurante e desconfortante, complexidade e vulnerabilidade a complicações, dentre as quais infecções e infestações, principalmente no ambiente hospitalar, fato agravado pelas drogas imunossupressoras utilizadas para o tratamento. Neste contexto, sobreleva-se a necessidade de ampliação do cuidado de enfermagem, sem limitar-se ao cumprimento das prescrições dos demais profissionais de saúde, objetivando atender às necessidades desta clientela e contemplá-la em todas as suas dimensões. Assim, este estudo teve como objetivo geral: propor uma Tecnologia de Cuidados de Enfermagem ao Cliente com Dermatoses Imunobolhosas (TCECDI) que reconheça padrões de conforto/bem-estar do cliente hospitalizado, antes e após a sua aplicação. A necessidade de trabalhar com dados imprecisos como a subjetividade do conforto/bem-estar, e com um grupo de doenças de incomum acometimento às pessoas, despertou o interesse pela lógica fuzzy, uma teoria que auxilia na compreensão dos conceitos que extrapolam as barreiras da lógica formal, permitindo estabelecer diferentes graus de pertinência dos atributos julgados relevantes, representando uma ferramenta que pode capturar informações subjetivas convertendo-as em valores de pertinência. Os atributos estabelecidos para avaliação do conforto nos três momentos foram: dor, mobilidade, padrão de sono, exposição do corpo e das lesões, conhecimento sobre a doença e autocuidado. Trata-se de um estudo quase experimental, interinstitucional, realizado no período de junho de 2012 a abril de 2013, em unidades de internação especializadas em dermatologia localizadas no Rio de Janeiro e no Mato Grosso do Sul. O delineamento alternativo para o ensaio clínico utilizado foi destinado a um único grupo não randomizado do tipo série temporal. As aferições foram realizadas antes (T0), 24 horas após (T1) e uma semana após (T2) o recebimento da intervenção. Como inexiste grupo controle, em cada sujeito considerou-se o seu próprio controle. Baseando-se nas classificações advindas da lógica fuzzy, na definição de conforto e nos três sentidos técnicos preconizados por Kolcaba: alívio, calma e transcendência,constatou-se a redução significativa no padrão de desconforto. Assim, pode-se afirmar que a implementação da TCECDI interferiu de forma expressiva e positiva nas necessidades de conforto dos sujeitos do estudo. Ao privilegiar a autonomia do enfermeiro e o seu saber específico, esta pesquisa contribuiu para a enfermagem como profissão, preenchendo lacunas nesta área do conhecimento, possibilitando o ensino qualificado, além de estimular entre os profissionais de saúde a reflexão, compreensão e desenvolvimento de outras pesquisas sobre a prática do cuidado em saúde, principalmente em dermatologia.

Avaliação do efeito anti-inflamatório e antiasmático da 15-deoxy-delta-12,14-prostaglandina J2 em modelos murinos de asma

A asma é um distúrbio crônico pulmonar caracterizado por inflamação, obstrução e remodelamento brônquico, levando a sintomas como sibilo, tosse e falta de ar. A terapia antiasmática consiste em corticosteroides inalados e agonistas β2 de curta ou longa duração. O tratamento é limitado por efeitos colaterais e refratariedade de alguns pacientes, justificando a necessidade de novas terapias. Estudos demonstram que a 15-deoxy-delta- 12,14-prostaglandina J2 (15d-PGJ2), um ligante endógeno de receptores ativados por proliferadores de peroxissomos do tipo gama (PPAR-γ), é capaz de reduzir a expressão de citocinas pró-inflamatórias, o que pode resultar em benefícios no tratamento de doenças com esse perfil. O objetivo deste estudo foi avaliar o potencial anti-inflamatório e antiasmático da 15d-PGJ2 em modelos experimentais de asma. Camundongos A/J machos foram sensibilizados nos dias 0 e 7 através de injeção subcutânea (s.c.), contendo ovoalbumina (OVA) e Al(OH)3, e desafiados com 4 instilações intranasais (i.n.) de OVA em intervalos semanais. O tratamento com 15d-PGJ2 (30 e 100 g/Kg, s.c.) foi realizado 30 min antes dos desafios a partir da terceira provocação antigênica. Em outro modelo, camundongos A/J foram desafiados intranasalmente com extrato de ácaro 3 vezes por semana durante 3 semanas. As administrações de 15d-PGJ2 (30, 70 e 100 g/Kg, s.c. e 0,65; 1,5 e 2,3 g/animal, i.n.) foram realizadas a partir da 3 semana, 30 min antes dos desafios. As análises ocorreram 24 h após o último desafio. Nossos resultados mostraram que, em camundongos previamente sensibilizados e desafiados com OVA, a administração de 15d-PGJ2 limitou significativamente o influxo peribrônquico de eosinófilos e neutrófilos, bem como a produção de muco por células caliciformes e fibrose sub-epitelial, além da hiperreatividade das vias aéreas e produção de IL-5. A redução do epitélio brônquico e das citocinas IL-13 e TNF-α foram observadas somente na maior dose administrada. No modelo HDM a inflamação e o remodelamento foram atenuados em todas as doses administradas do composto, enquanto que a hiperresponssividade brônquica foi inibida apenas nas doses de 70 e 100 μg/Kg (via sistêmica) e na dose intermediária dada topicamente (1,5 μg/animal, i.n.). Os níveis de citocinas foram atenuados pelo tratamento subcutâneo, porém somente os níveis de IL-17, eotaxina-1 e TNF-α foram inibidos com a dose intranasal de 0,65 g/animal. O aumento da expressão de NF-κB, induzido por provocação com HDM também foi reduzido significativamente pela administração de 15d-PGJ2. Em conjunto, nossos dados indicam que o tratamento com 15d-PGJ2 inibe alterações cruciais associadas à patogênese da asma, em modelos experimentais distintos da doença, demonstrando possuir grande potencial para controlar e reverter inflamação, hiperreatividade e remodelamento pulmonar desencadeados por provocação alérgica.

Management of water hyacinth, Eichhornia crassipes, in Lake Victoria Basin

Water hyacinth is a free-floating waterweed native to the Amazon River Basin in South America. In its native range, water hyacinth is not an environmental problem, although the weed is one of the most invasive alien plants in freshwater environments. Water hyacinth has the potential to become invasive through fast vegetative reproduction and rapid growth to accumulate huge biomass and extensive cover in freshwater environments. Over the last 150 years water hyacinth has invaded most countries in the tropics and sub-tropics, introduced by man, mainly for ornamental purposes. Such introductions led to the infestation of most freshwater-ways in the southern United States of America, parts of Australia, the pacific islands, and most countries in Asia and Africa. The extensive tightly packed mats of water hyacinth are often associated with devastating socio-economic and environmental impacts. Invasion by the weed has, therefore, often generated urgent costly problems associated with the weed biomass and its management. A classic example of such problems was triggered by the invasion and proliferation of water hyacinth in the Lake Victoria Basin during the 1980s (Freilink 1989, Taylor 1993, Twongo et al., 1995). The weed infestation marked the beginning of a decade of intensive and systematic campaign by the three riparian states (Kenya, Tanzania and Uganda) to bring weed proliferation under control. The discussions in this Chapter span over ten years of dealing with the challenges paused by the imperative to manage infestations of water hyacinth in the Lake Victoria Basin. The challenges included the need to understand the dynamics of water hyacinth infestation; its distribution, proliferation and impact modalities; and the development and implementation of appropriate weed control strategies and options. Most specific examples were taken from the Ugandan experience (NARO, 2002).

Knowledge, perceptions, impacts and roles of lakeside communities and institutions in the sustainable control of water hyacinth

The massive water hyacinth mats that covered water bodies in the 1990s had serious social and economic impacts. They affected fishing, transportation, water quality and health of fishing communities as well as production of goods and services of lake-based institutions (commercial establishments). At peak infestations, the communities and institutions were aware of and participated readily in control effort. However, after the major collapse of hyacinth in 1998, some of them relaxed in their control efforts. The status of knowledge, perception, impacts, preparedness and role of the lakeside communities and institutions to control the weed has, therefore, been monitored since the major resurgence of the weed to find out if the lakeside communities and institutions still perceive water hyacinth as a problem and the extent to which they are prepared to sustain control.

Environmental factors influencing composition, abundance and distribution of water hyacinth

Relationships between nutrient concentrations and water hyacinth biomass and composition have been studied in the shallow inshore bays of lakes Victoria, Kyoga and Albert. Additional information was obtained from Victoria Nile, Albert Nile and Kagera River. In this section, seasonal changes in nutrients and oxygen concentrations are used to explain changes in water hyacinth composition, biomass and distribution in Lake Victoria. Lake Victoria is of particular interest because it experienced strong hyacinth infestations in 1995, a sink in 1998 and resurgence in 2001. The lake has also been extensively sampled and provides time series data in nutrient, oxygen, mixing and thermal stratification which provide an opportunity to relate water hyacinth distribution and biomass to environmental factors. The possible origins and impacts of nutrient loads into Lake Victoria are also discussed in relation to water hyacinth proliferation and distribution especially in relation to known 'hot-spots'.

Application of electrochemical impedance spectroscopy for monitoring allergen-antibody reactions using gold nanoparticle-based biomolecular immobilization method

Gold nanoparticles were used to enhance the immobilization amount and retain the immunoactivity of recombinant dust mite allergen Der f2 immobilized on a glassy carbon electrode (GCE). The interaction between allergen and antibody was studied by electrochemical impedance spectroscopy (EIS). Self-assembled Au colloid layer (Phi = 16 nm) deposited on (3-mercaptopropyl)trimethoxysilane (MPTS)-modified GCE offered a basis to control the immobilization of allergen Der f2. The impedance measurements were based on the charge transfer kinetics of the [Fe(CN)(6)](3-/4-) redox pair, compared with bare GCE, the immobilization of allergen Der f2 and the allergen-antibody interaction that occurred on the electrode surface altered the interfacial electron transfer resistance and thereby slowed down the charge transfer kinetics by reducing the active area of the electrode or by preventing the redox species in electrolyte solution from approaching the electrode. The interactions of allergen with various concentrations of monoclonal antibody were also monitored through the change of impedance response. The results showed that the electron transfer resistance increased with increasing concentrations of monoclonal antibody.

Equivalencia fenomenológica entre fenómenos y equivalencia fenomenológica entre definiciones

Presentamos resultados relativos a la equivalencia matemática y fenomenológica de la definición de límite finito de una sucesión y la definición de sucesión de Cauchy. Para ello enunciamos dos criterios que permiten determinar cuando dos fenómenos son equivalentes y cuando lo son dos definiciones, desde un punto de vista fenomenológico. A continuación y usando estos resultados realizamos avances significativos para demostrar en un futuro próximo que la definición de límite finito de una función en el infinito y la condición de Bolzano-Cauchy, además de ser equivalentes matemáticamente también lo son fenomenológicamente. Para ello enunciamos los fenómenos organizados por la definición de Bolzano-Cauchy que convenimos en llamarla definición de función de Cauchy.

Marco teórico y metodológico para el estudio del límite

Nuestras investigaciones dan cabida, con los mismos métodos, a diferentes nociones del límite, como límite finito de una sucesión o límite finito de una función en un punto. Consideramos tres elementos relacionados: fenomenología, sistemas de representación y pensamiento matemático avanzado. En la primera parte lo explicamos y presentamos ideas de otros marcos teóricos. Hemos usado las mismas herramientas metodológicas para descubrir y estudiar los fenómenos organizados por tres casos de límite finito y para reconocer esos fenómenos en libros de texto. Además, hemos desarrollado instrumentos para mostrar los fenómenos que emplean alumnos y profesores. En la segunda parte describimos los métodos usados para extraer información de libros de texto y alumnos.

Population-Dynamics Of Mytilicola-Intestinalis In Mytilus-Edulis In South West England

The population dynamics of Mytilicola intestinalis Steuer in mussels (Mytilus edulis L.) from the River Lynher, Cornwall, England, have been studied over 3 years. By transplanting uninfested mussels from the River Erme, South Devon, into the Lynher mussel bed, the study was extended to the growth and development of new infestations under natural conditions. Female Mytilicola intestinalis are shown to breed twice, and two generations of parasites coexist for most of the year, with recruitment taking place in summer and autumn. One generation contributes its first brood to the autumn recruits before overwintering and contributing its second brood to the following summer's recruits. The other generation overwinters as juvenile and immature stages to contribute its two broods successively to the summer and autumn recruits. Environmental temperatures are believed to control the rates of development at all stages rather than acting as triggers in the onset or cessation of breeding at specific times. There is no evidence to support the contention that heavily infested mussels are killed, and parasite mortality is shown to be density-independent.

Compound-specific isotope analysis of amino acids: A tool to unravel complex symbiotic trophic relationships

Carbon and nitrogen stable isotope ratios of amino acids (δ13CAA and δ15NAA) have been recently used to unravel trophic relationships in aquatic and terrestrial environments. However, none have studied the specific case of a symbiotic relationship. Here we use the stable isotope ratios of amino acids (AAs) to investigate the link between a scarab larva (Pericoptustruncatus) and its mite guest (Mumulaelaps, Mesostigmata: Laelapidae: Hypoaspidini). Five scenarios for the relationship between larva and mite were proposed and δ13CAA and δ15NAA respective data and patterns helped eliminate those that were inconsistent. The calculated gap of two trophic levels ruled out a parasitic trophic relationship scenario. The trophic relationship between P. truncatus was shown to most likely be commensalistic with the mites feeding on the larva's castings. Alongside this study, a comparison with the stable isotope bulk analysis method was made and demonstrated that the AA method brings a significant refinement to the results by providing a means of determining absolute tropic level without the need for prior knowledge of the isotopic composition of primary source material.
