Cirurgia no Aspergiloma Pulmonar: Experiência Mono-Institucional
Correia, Silvia da Silva; Serviço de Pneumologia. Hospital Sousa Martins. Unidade Local de Saúde. Guarda. Portugal.Introdução: O aspergiloma ou micetoma é resultado da colonização saprofítica de uma cavidade pulmonar pelo Aspergillus. A cirurgia do aspergiloma é o único tratamento eficaz a longo prazo mas a alta incidência de complicações no intra e no pós-operatório fazem desta um tema controverso.Objetivos: Análise da experiência de um Centro de Cirurgia Cardiotorácica nos doentes com aspergiloma pulmonar e avaliação dos ...
O campo na cidade: as hortas e os hortelões de Lisboa
Bernardo, João ManuelAgricultural production faces a complex situation related to the unsustainability of many intensive agriculture, biodiversity losses and the necessary compatibilisation of agriculture and nature conservation, increasing use of soils to produce biofuels, decreasing availability at world level of good agricultural soils, climatic contingencies. As a result, prices of agricultural products rise. Apparently the era...
A Natureza, a Ideologia, o Sagrado
Bernardo, João ManuelIn a time of secularization, skepticism regarding ideologies, and general disenchantment, nature occupied a central place. In the context of the sacred-profane opposition of the cultural sociology, the sacred character of nature is briefly analyzed in relation to city vs. nature dichotomy, genetically modified organisms, organic food, and natural products. Nature is also the object of ideologies and social mov...

Fish-based groups for ecological assessment in rivers: the importance of enviro...
Matono, Paula; Bernardo, João Manuel; Ferreira, Maria Teresa; Formigo, Nuno; Raposo Almeida, Pedro; Ilhéu, MariaThe use of river-types is of practical value, serving as groups for which assessment procedures can be developed and applied. An abiotic typology was set by the Portuguese Water Agency, mainly based on 6 major morphoclimatic regions. However, to be biologically meaningful, this typology should fit the distribution patterns of the biological quality elements communities proposed in Water Framework Directive unde...
Effects of hydrological variability on fish assemblages in small Mediterranean ...
Matono, Paula; Bernardo, João Manuel; Oberdorff, Tierry; Ilhéu, MariaSmall Mediterranean streams are shaped by predictable seasonal events of flooding and drying over an annual cycle, and present a strong inter and intra-annual variation in flow regime. Native fish assemblages in these streams are adapted to this natural evironmental variability. The distinction of human-induced disturbances from the natural ones is thus a crucial step before assessing the ecological status of t...

Dispersal and coexistence of two non-native crayfish species (Pacifastacus leni...
Bernardo, João Manuel; Costa, Ana Manuel; Bruxelas, Sofia; Teixeira, AmílcarNE Portugal is one of the most isolated and low populated regions of Western Europe. Recently, two American crayfish species reached this area: signal crayfish Pacifastacus leniusculus coming from Spain and red swamp crayfish Procambarus clarkii in its northward expansion. The dispersion of both species was followed throughout the last decade in river Maçãs (Douro catchment). Our results support the hypothesis ...
Tipologia fluvial para Portugal Continental com base no elemento peixes.
Ilhéu, Maria; Matono, Paula; Formigo, Nuno; Ferreira, Maria Teresa; Almeida, Pedro Raposo; Cortes, Rui; Bernardo, JoãoA definição de tipos de massas de água é uma etapa fundamental do processo de avaliação ecológica preconizado pela Directiva-Quadro da Água (DQA). Só assim é viável definir situações de referência e, comparativamente, classificar o estado ecológico de cada tipo de rio. A necessidade de produzir e aplicar índices piscícolas no âmbito da implementação da DQA justificou a definição de tipos de rios com base no ele...
Desenvolvimento de um índice piscícola para os rios de Portugal Continental.
Matono, Paula; Ilhéu, Maria; Formigo, Nuno; Ferreira, Maria Teresa; Almeida, Pedro Raposo; Cortes, Rui; Bernardo, JoãoThe Water Framework Directive advocates an assessment of ecological quality of rivers based on hydromorphology and biological elements, including fish fauna. This topic has been poorly developed in Portugal, and the existing approaches are mainly based on expert knowledge and not on sensitivity analysis. This work presents the biological metrics responsive to different types of anthropogenic pressures and the b...
