Deteção e Quantificação Precoce de Clostridium perfringens em Frangos de Crescimento Rápido e de Plumagem Branca na Região de Lisboa e Vale do Tejo

Clostridium perfringens é uma bactéria anaeróbia Gram positiva, formadora de esporos e produtora de toxinas capazes de causar um amplo espectro de doenças em humanos e animais. Em frangos de crescimento rápido e de plumagem branca pode causar lesões e manifestações clínicas severas como enterite necrótica aviária (ENA), associada a uma baixa eficiência produtiva e avultadas perdas económicas. Neste estudo pretendeu-se avaliar a utilização de um teste de ensaio imunocromatográfico de fluxo lateral, o Clostridium FirstTestTM, para deteção e quantificação precoce de C. perfringens em frangos de crescimento rápido e plumagem branca e posterior relação entre a presença do agente e as características dos bandos (peso médio à chegada, idade dos bandos à amostragem), fatores ambientais (densidade populacional, temperatura ambiente, humidade da cama) e os indicadores de produção (ganho médio diário, Índice de Conversão Alimentar e percentagem de mortalidade). Para tal, foram analisadas amostras fecais de trinta bandos, em dezoito explorações integradas, na Região de Lisboa e Vale do Tejo. De acordo com a classificação do Clostridium FirstTestTM, dos trinta bandos amostrados entre o décimo primeiro e o décimo quinto dia de vida, 30 % foram classificados como “Positivo” (n=9) e 10 % foram classificados como “Muito Positivo” (n=3); apresentando concentrações médias de C. perfringens de 0,1322 ng/ml e 0,3267 ng/ml, respectivamente. Os restantes bandos, 60% (n=18), foram considerados “Normal” e apresentaram concentrações médias de C. perfringens de 0,0283 ng/ml. As amostras fecais dos bandos classificados de “Positivo” e “Muito Positivo” foram posteriormente sujeitas a análise microbiológica apresentando ambos os grupos unidades formadoras de colónias (UFC), identificadas como C. perfringens. Verificou-se que não existe relação entre os resultados do Clostridium FirstTestTM e as características dos bandos, os fatores ambientais e os indicadores de produção. Verificou-se uma diminuição dos níveis de C. perfringens nos bandos sujeitos a tratamento.

Günter Strauss e a Colecção de Minerais do Museu Mineiro do Louzal

Günter Strauss is Ph.D. in geology from the University of Munich in 1965. He is a German living by long time in Spain. Naw he is a SAPEC High Advisser His doctoral thesis, submitted in 1965, with the title "About the Geology of the Province of pyrite Southwest of the Iberian Peninsula and its oil fields, especially in the pyrite mine Louzal - Portugal" Systematized the term" Iberian Pyrite Belt ", called for the deposits of iron ore cuprífera, rich in sulfur and other metallic minerals, which occurs between the rivers Sado and Guadalquivir, where they settled several mining complexes, of Louzal, Rio Tinto, through Castro Verde, Santo Domingo and Tharsis. Local mining tradition with an ancient where today seeks to preserve the legacy and memory of mining through measures to enhance equity. The result of work carried out Louzal then formed the basis of geological and documentary collection that has survived and has been proposed for cultural units under the activities of the mining museum Louzal. The richness and importance of this collection, consisting of several hundred documents, geological samples classified, minerals and cartography, comes from its presence Situ"In its state of preservation, that despite the various threats it is still within reach of their preservation, and the relative rarity of such collections, with the units of mining production. This communication aims to reveal the contribution of Mr Strauss for the formation of this collection and submit his proposal for cultural units, with the hope that those responsible for safeguarding them understand the need for its preservation and dissemination. So discuss the scientific and professional way Günter Strauss, a geologic formation of the estate of Mines Louzal, and the draft musealization proposition.

O Cuidador de Enfermagem e o Cuidar em Uma Unidade de Terapia Intensiva; The Nursing Caregiver and the Caring in Intensive Care Units

There are several aggressive factors in Intensive Care Units (ICU), which reach not only patients, but the nursing caregivers, since they participate in complex procedures and death of patients. Nursing caregivers may have difficulties on their daily work routine that can influence the way of care. The goal of this study was to identify the aspects of nursing caregivers working in adult ICU. It is a describe-exploratory study with qualitative approach, developed among 21 ICU adult nursing caregivers of a school hospital in Paraná. The data were collected in May and July, 2009 by recorded and transcribed semi-structured interviews. Four categories for analysis were identified: the aspects of ICU assistance, the meaning of healthcare for the nursing caregivers, the understanding of healthcare positive aspects and disclosing the difficulties of caring. The results revealed that caring is related to some factors such as mixed feelings, the mental and physical damage caused by stress; the understanding of total caring, scientific-technique procedures, family engagement in the assistance and humanization. The positive aspects are related to the welfare due to satisfaction in the work done and recognition of work. The difficulties involved death situations, psychological and biological damages, establishing links with patients and the uncaring toward the nursing caregivers.
