Fisiopatologia da microcirculação coronária e perfusão do miorcárdio : ecocardiografia de contraste do miocárdio e doppler transtorácico

RESUMO: Este trabalho tentou contribuir para a caracterização da fisiopatologia da microcirculação coronária em diferentes formas de patologia com o auxílio da ecocardiografia transtorácica. Com a aplicação da ecocardiografia Doppler transtorácica foi efectuado o estudo da reserva coronária da artéria descendente anterior e com a ecocardiografia de contraste do miocárdio foram analisados parâmetros de perfusão do miocárdio como a velocidade da microcirculação coronária, o volume de sangue miocárdico e a reserva de fluxo miocárdico. Estas técnicas foram utilizadas em diferentes situações fisiopatológicas com particular interesse na hipertrofia ventricular esquerda de diferentes etiologias como a hipertensão arterial, estenose aórtica e cardiomiopatia hipertrófica. Também na diabetes mellitus tipo 2 e na doença coronária aterosclerótica, estudámos as alterações da microcirculação coronária. Com a mesma técnica de ecocardiografia de contraste do miocárdio foi analisada a perfusão do miocárdio num modelo experimental animal sujeito a uma dieta aterogénica. Além das conclusões específicas em relação a cada um dos trabalhos efectuados há a referir como conclusões gerais a sua fácil aplicabilidade e exequibilidade em âmbito clínico, a sua reprodutibilidade e precisão. Quando comparadas com técnicas consideradas de referência mostraram resultados com significativa correlação estatística. Em todos os doentes e nos grupos controle foi possível comprovar e quantificar o gradiente de perfusão transmural em repouso e durante a acção de stress vasodilatador, relevando a importância da perfusão sub-endocárdica na função do ventrículo esquerdo. O estudo da microcirculação coronária no grupo de doentes com hipertrofia ventricular esquerda revelou que no grupo com hipertensão arterial existe disfunção da microcirculação coronária ainda antes de se observar aumento de massa do ventrículo esquerdo, e que esta disfunção é diferente em função da geometria ventricular. Nos doentes com estenose aórtica foi demonstrado que além da disfunção da microcirculação coronária, explicada pelo fenómeno de hipertrofia, existe outro componente extrínseco que depois de corrigido através de cirurgia de substituição valvular, conduziu a uma parcial normalização dos valores de reserva coronária. Na cardiomiopatia hipertrófica observou-se uma grande heterogeneidade de perfusão transmural e foi documentado, em imagens de ecocardiografia de contraste do miocárdio e após análise paramétrica, a ausência de perfusão do miocárdio na região sub-endocárdica durante o stress vasodilatador de reserva coronária diminuídos em fases precoces de evolução da doença. Foi demonstrado que a reserva coronária na DM2 em fases mais avançadas estava significativamente diminuída. Descrevemos também em doentes com DM2 e sem doença coronária angiográfica a existência de disfunção da microcirculação coronária. Durante o stress vasodilatador, observámos e documentámos neste grupo de doentes, a existência de defeitos de perfusão transitórios ou de diminuição da velocidade da microcirculação coronária. No grupo de doentes com doença coronária confirmámos o interesse da avaliação da reserva coronária após intervenção percutânea na definição de prognóstico pós EAM, em termos de recuperação funcional do ventrículo esquerdo. Em doentes com BCRE e de difícil estratificação de risco, foi possível calcular o valor de reserva coronária e estratificar o risco de doença coronária. Num modelo experimental animal demonstrámos a exequibilidade da técnica de ECM, e verificámos que nessas condições experimentais, uma sobrecarga aterogénica na dieta, ao fim de 6 semanas, comprometia severamente a reserva coronária. Estes resultados foram parcialmente reversíveis quando à dieta foi adicionada uma estatina. Estas técnicas pela sua não invasibilidade, fácil acesso, repetibilidade e inocuidade perspectivam-se de grande utilidade na caracterização de doentes com disfunção da microcirculação coronária, nas diferentes áreas de diagnóstico, terapêutica e prevenção. A possibilidade de adaptar a técnica em modelos experimentais animais também nos parece poder vir a ter grande utilidade em investigação.----------------ABSTRACT: This work is intended to be a contribution to the study of coronary microcirculation applying new echocardiographic techniques as transthoracic Doppler echocardiography of coronary arteries and myocardial contrast echocardiography. Coronary flow reserve may be assessed by transthoracic Doppler echocardiography, and important functional microcirculation parameters as microcirculation flow velocity, myocardial blood volume and myocardial flow reserve may be evaluated through myocardial contrast echocardiography. Microcirculation was analysed in different pathophysiological settings. We addressed situations with increased left ventricular mass as systemic arterial hypertension, aortic stenosis and hypertrophic cardiomyopathy. Also coronary microcirculation was studied in type 2 Diabetes and in different clinical forms of atherosclerotic coronary artery disease. Specific and detailed conclusions were withdrawn from each experimental work. In the overall it was concluded that these two techniques were important tools to easily assess specific pathophysiological information about coronary microcirculation at bed side which would be difficult to get through other techniques. When compared with gold standard techniques, similar sensibility and specificity was found. Because of their better temporal and spatial resolution it was possible to analyse the importance of transmural perfusion gradients, both in basal and during vasodilatation, and their relation to ischemia, and mechanical wall kinetics, as wall thickening and motion. Coronary microcirculation dysfunction was found in systemic arterial hypertension early evolution stages, also related to different left ventricular geometric patterns. Different etiopathogenical explanations for aortic stenosis coronary microcirculation dysfunction were analysed and compared after aortic valve replacement. Transmural myocardial perfusion heterogeneity pattern was observed in hypertrophic cardiomyopathy which was aggravated during adenosine challenge. Coronary microcirculation dysfunction was diagnosed in type 2 diabetes both with coronary artery disease and with normal angiographic coronary arteries. Dynamic transitory subendocardial perfusion defects with adenosine vasodilatation were visualized in these patients.In patients with left branch block, transthoracic Doppler echocardiography was able to suggest a coronary reserve cut-off value for risk stratification. Also it was possible with this technique to calculate coronary flow reserve and predict restenosis after PTCA Again, in an experimental animal model, applying myocardial contrast echocardiography technique it was possible to study the consequences of an atherogenic diet and statins action on the coronary microcirculation function. Because these techniques are easily performed at bed side, are harmless, use no ionizing radiation and because of their repeatability, reproducibility and accuracythey are promissory tools to assess coronary microcirculation. Both in clinic and research areas these techniques will probably have a role in clinical diagnosis, prevention and therapeutically decision.

Identification of dengue viruses in naturally infected Aedes aegypti females captured with BioGents (BG)-Sentinel traps in Manaus, Amazonas, Brazil

IntroductionIn Manaus, the first autochthonous cases of dengue fever were registered in 1998. Since then, dengue cases were diagnosed by the isolation of viruses 1, 2, 3, and 4.MethodsOne hundred eighty-seven mosquitoes were collected with BioGents (BG)-Sentinel traps in 15 urban residential areas in the Northern Zone of Manaus and processed by molecular tests.ResultsInfections with dengue viruses 1, 2, 3, and 4 and a case of co-infection with dengue viruses 2 and 3 were identified.ConclusionsThese findings corroborate the detection of dengue in clinical samples and reinforce the need for epidemiological surveillance by the Health authorities.

Flood resilient housing recovery models: a theoretical case study in Maldives

Natural disasters are events that cause general and widespread destruction of the built environment and are becoming increasingly recurrent. They are a product of vulnerability and community exposure to natural hazards, generating a multitude of social, economic and cultural issues of which the loss of housing and the subsequent need for shelter is one of its major consequences. Nowadays, numerous factors contribute to increased vulnerability and exposure to natural disasters such as climate change with its impacts felt across the globe and which is currently seen as a worldwide threat to the built environment. The abandonment of disaster-affected areas can also push populations to regions where natural hazards are felt more severely. Although several actors in the post-disaster scenario provide for shelter needs and recovery programs, housing is often inadequate and unable to resist the effects of future natural hazards. Resilient housing is commonly not addressed due to the urgency in sheltering affected populations. However, by neglecting risks of exposure in construction, houses become vulnerable and are likely to be damaged or destroyed in future natural hazard events. That being said it becomes fundamental to include resilience criteria, when it comes to housing, which in turn will allow new houses to better withstand the passage of time and natural disasters, in the safest way possible. This master thesis is intended to provide guiding principles to take towards housing recovery after natural disasters, particularly in the form of flood resilient construction, considering floods are responsible for the largest number of natural disasters. To this purpose, the main structures that house affected populations were identified and analyzed in depth. After assessing the risks and damages that flood events can cause in housing, a methodology was proposed for flood resilient housing models, in which there were identified key criteria that housing should meet. The same methodology is based in the US Federal Emergency Management Agency requirements and recommendations in accordance to specific flood zones. Finally, a case study in Maldives – one of the most vulnerable countries to sea level rise resulting from climate change – has been analyzed in light of housing recovery in a post-disaster induced scenario. This analysis was carried out by using the proposed methodology with the intent of assessing the resilience of the newly built housing to floods in the aftermath of the 2004 Indian Ocean Tsunami.

Sustainable urban planning: parameters to the operational process

In modern society, energy consumption and respect for the environment have become essential aspects of urban planning. The rising demand for alternative sources of energy, coupled with the decline in the construction sector and material usage, gives the idea that the thinking on modern cities, where attention is given to reduced energy consumption, savings, waste recycling and respect for the surrounding environment, is being put into practice. If we examine development of the city over recent centuries, by means of the theories of the most famous and influential urban planners, it is possible to identify the major problems caused by this type of planning. For this reason, in recent urban planning the use of systems of indicators that evaluate and certify land environmentally and energetically guides the master plan toward a more efficient city model. In addition the indicators are targeted on key factors determined by the commissioner or the opportunities the territory itself provides. Due the complexity of the environmental mechanics, the process of design and urban planning has become a challenging issue. The introduction of the indicators system has made it possible to register the life of the process, with a spiral route that allows the design itself to be refined. The aim of this study, built around the creation of a system of urban sustainability indicators that will evaluate highly eco-friendly cities, is to develop a certification system for cities or portions of them. The system will be upgradeable and objective, will employ real data and will be concerned with energy production and consumption.

Dispondo de si : autonomia, género e envelhecimento nos quotidianos de saúde

Esta tese de doutoramento tem como objectivo geral compreender as experiências de autonomia individual na actual geração de adultos mais velhos, enquadrados pelas construções identitárias de género e assumindo como plataforma de observação as vivências quotidianas de saúde. Para tanto, justifica-se a centralidade do valor da autonomia individual na contemporaneidade, para depois se problematizar o conceito a partir de uma perspectiva feminista, com base na conceptualização proposta por este corpo teórico. O feminismo propõe a adopção do conceito de autonomia relacional, que ao reconhecer a natureza social do self e das identidades, é capaz de proporcionar uma leitura crítica e contextualizada da autonomia de cada sujeito, por integrar não só as especificidades, estímulos, oportunidades e contingências de um tempo e de um espaço social, como também o poder resolutivo, transformador e de resistência da agência individual. A vivência da velhice constitui, cada vez mais, um exercício de individualidade. No envelhecer, a vivência da saúde ganha especiais contornos. Não só porque o cuidar de si se tornou um aspecto biográfico de progressiva acentuação, como também por ser este um tempo da vida em que os dilemas, inquietações e exigências com o corpo se acentuam. A individualização dos trajectos biográficos que nas sociedades contemporâneas surge com cada vez maior expressão sugere a importância do estudo das diferentes ecologias sociais, com base na precisão e no detalhe. A tese adoptou uma estratégia metodológica de estudos de casos, concretizada num estudo de caso múltiplo, de tipo qualitativo. Os sentidos conferidos às experiências da autonomia individual pela actual geração de adultos mais velhos, nos seus quotidianos de saúde, mobilizam e matizam diferentes modelos culturais, iluminando a ideia de uma transição sociocultural que abandona parcialmente certos aspectos, mas que mantém tantos outros. No envelhecer, a vivência da autonomia individual é mediatizada por diferentes performatividades femininas e masculinas, tendo sido três os espaços principais de expressão social da autonomia, resultantes do seu cruzamento com o género, enquanto dimensão de análise principal. Tem-se que estas diferenças entre espaços factoriais vêm demonstrar o hibridismo dos posicionamentos resultante da crescente individualidade das trajectórias de vida. Face à saúde, a capacidade de adaptação e de auto-gestão mais positivos relacionam-se, face às mulheres, com a expressão singular de uma maior individualidade e, face aos homens, com o valor social conferido a diferentes masculinidades.

Improving selective collection of urban waste using a business intelligence system

Today recovering urban waste requires effective management services, which usually imply sophisticated monitoring and analysis mechanisms. This is essential for the smooth running of the entire recycling process as well as for planning and control urban waste recovering. In this paper we present a business intelligence system especially designed and im- plemented to support regular decision-making tasks on urban waste management processes. The system provides a set of domain-oriented analytical tools for studying and characterizing poten- tial scenarios of collection processes of urban waste, as well as for supporting waste manage- ment in urban areas, allowing for the organization and optimization of collection services. In or- der to clarify the way the system was developed and the how it operates, particularly in process visualization and data analysis, we also present the organization model of the system, the ser- vices it disposes, and the interface platforms for exploring data.

Diversity of sand flies in domiciliary environment of Santarém, state of Pará, Brazil: species composition and abundance patterns in rural and urban areas

This paper aimed to evaluate the richness, abundance and frequency of sand fly occurrence in rural and urban areas American visceral Leishmaniasis -AVL is endemic in the study area of Santarém municipality, Pará state. Sand flies were collected during 1995-2000, using CDC light traps placed in neighborhoods and rural areas of the municipality. A total of 53.454 individuals and 26 species of sand flies were collected. The most abundant species in both urban and rural environments was Lutzomyia longipalpis, vector of AVL in the area. The highest species richness by capture was in rural area. In all years sampled, the largest number of species of sand fly collected was always in rural areas. The species of sand flies in urban and rural area were similar in 11 species. In the rural area other 11 species were found, a total of 22 species. Shannon-Wiener index ranged from 0.12 to 0.84 at rural areas and 0.08 to 0.34 at urban ones. In general, rural localities showed higher diversity (H') of phlebotomines than urban ones. Individual-based rarefaction curves for each area demonstrated that urban localities had the lowest expected number of phlebotomine species and the richest rural ones reach higher expected values with lower amount of individuals than urban sites. The most frequent species were Lutzomyia longipalpis, Evandromyia carmelinoi and Bichromomyia flaviscutellata.
