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.

Prevalence of Chagas disease in blood donors at the Uberaba Regional Blood Center, Brazil, from 1995 to 2009

INTRODUCTION: A retrospective study was conducted to assess the occurrence of blood donations that were ineligible due to Chagas disease infection from 1995 to 2009 at the Uberaba Regional Blood Center (HRU), Brazil, verify the tendency of this ineligibility, and describe the epidemiologic profile of the donors. METHODS: Retrospective studies of serological ineligibility due to Chagas disease, statistical analysis by means of the chi-square test and odds ratio, study of the tendencies using a dispersion graph and the linear correlation coefficient (r) were performed. RESULTS: In the period under study, a 0.2% serum prevalence of ineligibility due to Chagas disease was found, with a significant drop in ineligible donations from 2001 to 2009. Among the serum positive-donors, there was a significant predominance among those aged 30 years or above and non-single individuals. CONCLUSIONS: The results show a rate of occurrence that is lower than that described in literature, as well as a progressive drop during the 15 years under assessment. Such results are a consequence of systematic combat of the vector since the 70s and the progressive and consistent increase of returning donors, resulting in a drop of the contamination risk factor by means of blood transfusion and in the improvement of the quality of hemotherapy practices in the HRU.

Epidemiology of the viral hepatitis B and C in female prisoners of Metropolitan Regional Prison Complex in the State of Goiás, Central Brazil

INTRODUCTION: Little information regarding hepatitis B virus (HBV) and hepatitis C virus (HCV) infections among Brazilian female prisoners exists. This study investigated the prevalence and risk factors associated with HBV and HCV infections and identified viral genotypes among female prisoners in Goiás, Central Brazil. METHODS: Women incarcerated in the largest prison in the State of Goiás were invited to participate in the study. All female prisoners were interviewed and tested for the detection of hepatitis B surface antigen (HBsAg), antibodies against HBsAg (anti-HBs), against hepatitis B core antigen (anti-HBc), and antibody against HCV (anti-HCV) by ELISA. HBsAg and anti-HCV positive samples were tested for HBV DNA and HCV RNA and genotyped, respectively. RESULTS: Participants (n=148; 98.6%) completed the study with an overall HBV prevalence of 18.9%. Age >30 years, a low education level, sex with a sexually transmitted diseases carrier, and a male sexual partner serving in the same penitentiary were associated with HBV infections. Only 24% of the women were anti-HBs positive suggesting previous HBV vaccination. Nine female prisoners (6.1%) were anti-HCV positive. Age >40 years, injecting drug use and length of incarceration were statistically associated with anti-HCV antibodies. Five samples were HCV RNA positive and classified as genotypes 1 (subtypes 1a; n=3 and 1b; n=1) and 3 (subtype 3a; n=1). The HBsAg-reactive sample was HBV DNA positive and genotype A. CONCLUSIONS: These findings highlight the necessity of public policies to control hepatitis B and C infections and emphasize the importance of hepatitis B vaccination in prison environments.

Overcoming the “European Paradox”: The role of Regional Innovation Systems (RIS) in translating R&D investments into economic and employment growth

The emergence of the so-called “European Paradox” shows that R&D investment is not maximally effective and that increasing the scale of public R&D expenditures is not sufficient to generate employment and sustained economic growth. Increasing Governmental R&D Investment is far from being a “panacea” for stagnant growth. It is worth noting that Government R&D Investment does not have a statistically significant impact on employment, indicating the need to assess the trade-offs of policies that could lead to significant increases in government expenditure. Surprisingly, Governmental R&D Employment does not contribute to “mass-market” employment, despite its quite important role in reducing Youth-Unemployment. Despite the negative side-effects of Governmental R&D Employment on both GVA and GDP, University R&D Employment appears to have a quite important role in reducing Unemployment, especially Youth-Unemployment, while it also does not have a downside in terms of economic growth. Technological Capacity enhancement is the most effective instrument for reducing Unemployment and is a policy without any downside regarding sustainable economical development. In terms of wider policy implications, the results reinforce the idea that European Commission Research and Innovation policies must be restructured, shifting from a transnational framework to a more localised, measurable and operational approach.

Risk factors associated with hantavirosis fatality: a regional analysis from a case-control study in Brazil

Introduction: In Brazil, hantavirus cardiopulmonary syndrome (HCPS) has a high lethality rate that varies by region. This study aimed to identify the risk factors associated with fatal hantavirosis. Methods: This study was a case-control study that included all laboratory confirmed cases of hantavirosis. The cases were stratified by the different Brazilian regions using data from the Notifiable Diseases Information System. “Cases” were patients who progressed to death, whereas “controls” were patients who were cured. The odds ratio (OR) and the adjusted OR were calculated. Results: Overall, 158 cases and 281 controls were included in this study. In the Midwest region, the cases were 60% less likely to present with flank pain, and the time between the beginning of symptoms and death was shorter than the time between the beginning of symptoms and a cure. In the Southeast region, the cases were 60% less likely to present with thrombocytopenia or reside in rural areas compared to those who progressed to a cure. Additionally, the cases sought medical assistance, notification and investigation more quickly than the controls. In the Southern region, the cases that died were 70% less likely to be male compared to the controls. Conclusions: HCPS manifests with nonspecific symptoms, and there are few published studies related to the condition, so determining a patient's therapeutic strategy is difficult. This study presents findings from different Brazilian regions and highlights the need for further investigations to improve comprehension about regional risk factors associated with hantavirosis and to reduce morbimortality.

Southern Modernisms. Critical Stances through Regional Appropriations. Conference proceedings

The hegemonic definition of Modernism has been subjected to an intense critical revision process that began several decades ago. This process has contributed to the significant broadening of the modernist canon by challenging its primal essentialist assumptions and formalist interpretations in the fields of both the visual arts and architecture. This conference aims to further expand this revision, as it seeks to discuss the notion of “Southern Modernisms” by considering the hypothesis that regional appropriations, both in Southern Europe and the Southern hemisphere, entailed important critical stances that have remained unseen or poorly explored by art and architectural historians. In association with the Southern Modernisms research project (FCT – EXPL/CPC-HAT/0191/2013), we want to consider the entrenchment of southern modernisms in popular culture (folk art and vernacular architecture) as anticipating some of the premises of what would later become known as critical regionalism. It is therefore our purpose to explore a research path that runs parallel to key claims on modernism’s intertwinement with bourgeois society and mass culture, by questioning the idea that an aesthetically significant regionalism – one that resists to the colonization of international styles and is supported by critical awareness – occurred only in the field of architecture, and can only be represented as a postmodernist turn.

Occult HBV infection status among chronic hepatitis C and hemodialysis patients in Northeastern Egypt: regional and national overview

INTRODUCTION: Occult hepatitis B infection (OBI) is considered to be one of the major risks for patients suffering from end-stage renal disease (ESRD) on regular hemodialysis (HD) and patients with chronic hepatitis C virus (HCV) infection. This study compared the prevalence of OBI among these two high-risk groups in the Suez Canal region, Northeastern Egypt, to obtain a better national overview of the magnitude of OBI in this region. METHODS: Serum samples were collected from 165 HD patients and 210 chronic HCV-infected patients. Anti-HCV antibody, hepatitis B surface antigen (HBsAg), total hepatitis B core (anti-HBc) antibody, and hepatitis B surface antibody (anti-HBs) were detected by enzyme-linked immunosorbent assay (ELISA). HCV RNA was detected using a quantitative real-time RT-PCR assay, and HBV was detected using a nested PCR. RESULTS: All patients were negative for HBsAg. A total of 49.1% and 25.2% of the patients in the HD and HCV groups, respectively, were anti-HBc-positive. In addition, more anti-HBs-positive patients were detected in the HD group compared to the HCV group (52.1% and 11.4%, respectively). Three cases were positive for HBV DNA in the HD group, while eighteen positive cases were detected in the HCV group. Both study groups showed significant differences in serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) level as well as anti-HBc, anti-HBs and HBV-DNA positivity. CONCLUSIONS: OBI was more prevalent among chronic HCV patients than HD patients in the Suez Canal region, Egypt, with rates of 8.5% and 1.8%, respectively. However, more precise assessment of this infection requires regular patient follow-up using HBV DNA detection methods.

A presente dissertação foi desenvolvida em colaboração com o Matadouro Regional do Alto Alentejo

COMPOSIÇÃO QUÍMICA E PERCENTUAL DE ADEQUAÇÃO DA DIETA REGIONAL DE MANAUS - AM.

A dieta regional de Manaus foi avaliada nutricionalmente por meio da análise química e percentual de adequação, tomando-se como referencial os padrões da National Academy of Science (19Ô9). A dieta foi elaborada utilizando-se os dados de Shrimpton & Giugliano (1979), para famílias com rendimentos de até dois salários mínimos mensais e preparadae de acordo com as técnicas culinárias habitualmente utilizadas pela população. Doe resultados obtidos, observou-se um déficit calorico de 54,3% para o homem adulto e 13,4% para a mulher adulta. Pas 1906 Kcal totale, os glicídios contribuíram com 60%, lipídios 20% e proteínas 20%. Quantitativamente, as proteínas estavam em níveis adequados, embora parte delas pudessem estar eendo utilizadas com finalidade energética. Dos minerais, o cálcio estava mais deficiente com um percentual de adequação da ordem de 50%. 0 ferro mostrou-se deficiente para a mulher adulta quando comparado com as necessidades recomendadae. Em relação ao teor de retino! proveniente do B-caroteno da dieta, o percentual foi de 12,6% e 15,0% respectivamente para homem e mulher. De acordo com os dados obtidos, concluiu-se que a dieta não atende às recomendações preconizadas para a maioria dos nutrientes estudados.

BIODISPONIBILIDADE DE ZINCO EM DIETA REGIONAL DE MANAUS, AM. ESTUDO EM RATOS

Foi estudada a biodisponibilidade de zinco em ratos recebendo uma dieta regional de Manaus, AM. A dieta foi elaborada segundo os dados de SHRIMPTON & GIUGLIANO, (1979) para famílias com rendimentos inferiores a 2 salários mínimos. O ensaio biológico com ratos da linhagem Wistar se baseou inicialmente, na depleção de zinco e vitamina A na lactação, adaptação dos filhotes com a dieta regional por 7 dias e período de repleção onde se realizou a suplementação com zinco de acordo com as recomendações do "COMMITTEE ON LABORATORY ANIMAL DIETS" (1979). Os resultados nos permitiram concluir que a quantidade de zinco presente na dieta, avaliada pelos parâmetros de medida de biodisponibilidade de zinco como crescimento, concentração nos órgãos e de enzima zinco dependente, foi utilizada adequadamente pelos animais, provavelmente pelos fatores promotores da dieta.

The drought of the century in the Amazon Basin: an analysis of the regional variation of rainfall in South America in 1926

The most severe drought in tropical South America during the 20th century occurred in 1926. This extreme El Nino year is further documented anecdotally, in an update of the river stage observations at Manaus, and in annual rainfall records. The annual rainfall anomaly is an east-west dipole over tropical South America, with drought to the west over the Amazon basin whose discharge is documented at Manaus, and with a surplus to the east and including the Nordeste region of Brazil. Speculations about a role for aerosol in aggravating the drought are discussed.

Portuguese publication in the aim of regional science: a study of articles published in RPER from 2003 to 2015

This paper is a study of the full content of articles published by RPER, the Portuguese Review of Regional Studies, from the time it was launched in 2003 until the first quarter of 2015. RPER is a journal edited by the Portuguese section of the European Regional Science Association, which was established in the first half of the 1980s. The Association (APDR) and the journal are the result of contributions by researchers and technicians from different scientific fields, including mainly Economics, Geography, Sociology, Engineering and Architecture. The main focus of these contributions is the socio-economic life of concrete sites, and the way this life is conditioned by resources and capabilities, the historical and cultural heritage and institutions. Content analysis was undertaken to identify the main subjects chosen during the total period under analysis, the nature of the articles published (theoretical or empirical) and the main analytical framework used. The analysis also covers sub-periods to investigate major trends found in terms of subjects chosen and analytical methods, questioning the rationale behind them. The paper concludes with a few notes regarding the social echo the research received and an identification of the main limitations of the research. In the first part of the article, we conduct a summary review of the genesis and evolution of Regional Science at international level to serve as a basis for the empirical approach developed.

As imigrantes brasileiras no jornalismo impresso regional

O estudo sobre a representação das brasileiras nos media é revisto sob vários aspectos e nos diversos meios de comunicação. Alguns estudos aprofundam a imagem das imigrantes, enquanto outros se concentram nos meios (rádio, televisão e imprensa). Existe ainda uma linha de investigação que se centra nos estudos da recepção. Todavia, verificámos a escassez de um estudo específico sobre a representação deste grupo no jornalismo de proximidade. Esta comunicação tem por objectivo apresentar parte dos resultados sobre a representação dos imigrantes brasileiros nas notícias publicadas durante o ano de 2007 em dois jornais regionais (um português – Diário do Minho – e um italiano – L'Adige). A escolha de um jornal externo ao contexto português foi extremamente enriquecedora para identificar possíveis convergências no tratamento dos imigrantes brasileiros (homens e mulheres) em diferentes contextos sócioculturais. Além disso, tanto Portugal como Itália foram países de forte emigração, influenciando os processos migratórios de ambos. A investigação inicial mostrou uma acentuada assimetria de género, o que nos levou a aprofundar a análise sob este aspecto. Observámos que os jornais analisados, em relação ao tratamento informativo da imigrante brasileira, trabalham na mesma linha dos jornais de âmbito nacional e, mesmo que em escala inferior, continuam a representar estas mulheres com um baixo estatuto, associadas a temas e comportamentos socialmente conotados com a marginalidade. De salientar que as imigrantes brasileiras que têm visibilidade nas peças noticiosas dos dois jornais são geralmente conotadas com a prostituição, clandestinidade, crime e exploração.
