Macro-forma como estratégia de organização do espaço urbano : acessibilidades

Em primeiro lugar, procura-se perceber de um modo geral, as relações entre a arquitectura e sociedade. Para isso, torna-se necessário analisar diferentes épocas, uma vez que estas relações são mutantes ao longo do tempo. O desenvolver do tema desenvolvimento urbano permite perceber a cidade como um organismo, e de que forma é que ela é afectada pela sociedade. Numa outra perspectiva, o tema das acessibilidades permite perceber os problemas de acesso nas cidades, e de que forma é que este pode ser melhorado. Torna-se fundamental perceber as relações da sociedade com os diferentes elementos do espaço público e que tipo de sentimentos lhes estão associados. Os diferentes elementos do espaço público das cidades são analisados de modo a perceber as diferentes realidades que lhe são inerentes. Assim é possível proceder a uma análise do território da área de intervenção com maior rigor. A partir da análise do território, é possível caracterizar o local através das suas potencialidades e problemas, definindo uma estratégia de intervenção. É desenvolvida uma proposta de intervenção para uma área da cidade de Viseu, que resulta de toda a base teórica e analítica do local, sendo proposto um projecto de arquitectura para a área de intervenção.On first place, I’ve looked in general way the relationships between arquitecture and society. For this is necessary to analyzed the different periods because the same relationships are always changing.The development of the theme “urban development” allows to understand of the city us an organism the same way how she is affected by the society. On the other way the theme “accessibility” allows to understand the problems of the access on cities and the same way how can be in proved. Is fundamental to understand the relationships of the society with the different elements of public space and the feelings that are associated by them. The different elements of public space of the cities are analyzed of one way to understand the reality that can be inherent. That way is possible to proceed of the analysis of the territory of the area of intervention with much better stringency. From the analysis of the territory it’s possible characterize the local with your potential and problems which as define one strategic of intervention. It developed an intervention in Viseu, which result a theoretical and analytical on the location chosen, being proposal to us on project of architecture on the area of intervention

Eight years of experience

Copyright © 2017 Sociedade Portuguesa de Cardiologia. Publicado por Elsevier España, S.L.U. All rights reserved.INTRODUCTION: Aortic stenosis is the most prevalent type of valvular disease in Europe. Surgical aortic valve replacement (SAVR) is the standard therapy, while transcatheter aortic valve implantation (TAVI) is an alternative in patients at unacceptably high surgical risk. Assessment by a heart team is recommended by the guidelines but there is little published evidence on this subject. The purpose of this paper is to describe the experience of a multidisciplinary TAVI program that began in 2008. METHODS: The heart team prospectively assessed 473 patients using a standardized approach. A total of 214 patients were selected for TAVI and 80 for SAVR. Demographic, clinical and procedural characteristics and long-term success rates were compared between the groups. RESULTS: TAVI patients were older than the SAVR group (median 83 vs. 81 years), and had higher surgical risk scores (median EuroSCORE II 5.3 vs. 3.6% and Society of Thoracic Surgeons score 5.1 vs. 3.1%), as did the patients under medical treatment only. These scores were unable to assess multiple comorbidities. Patients' outcomes were different between the three groups (mortality with SAVR 25% vs. TAVI 37.6% vs. conservative therapy 57.6%, p=0.001). CONCLUSIONS: The heart team program was able to select candidates appropriately for TAVI, SAVR and conservative treatment, taking into account the risk of both invasive treatments. The use of a prospective standardized heart team approach is recommended, but requires continuous monitoring to ensure effectiveness in a timely manner.publishersversionpublishe

Data from Portuguese centers

© 2022 Sociedade Portuguesa de Cardiologia. Published by Elsevier España, S.L.U.INTRODUCTION: During the Covid-19 pandemic there has been a general belief that hospital admissions for non-infectious causes, especially cardiovascular disease, have fallen. OBJECTIVES: To assess the impact of the pandemic on admissions for ST-elevation myocardial infarction (STEMI) during the first pandemic wave. METHODS: We performed a multicenter retrospective analysis of consecutive patients presenting with STEMI in two Portuguese hospital centers in two sequential periods - P1 (March 1 to April 30) and P2 (May 1 to June 30). Patients' clinical data and hospital outcomes were compared between the two periods for the years 2017 to 2019 and for 2020. RESULTS: During P1 in 2020, a reduction in the number of STEMI patients was observed in comparison with previous years (26.0±4.2 vs. 16.5±4.9 cases per month; p=0.033), as well as an increase in the number of mechanical complications (0.0% vs. 3.0%; p=0.029). Percutaneous coronary interventions in the setting of failed thrombolysis were more frequent (1.9% vs. 9.1%; p=0.033). An overall trend for longer delays in key timings of STEMI care bundles was noted. Mortality was higher during P1 compared to previous years (1.9% vs. 12.1%; p=0.005). CONCLUSIONS: During the first Covid-19 wave fewer patients presented with STEMI at the catheterization laboratory for percutaneous coronary intervention. These patients presented more mechanical complications and higher mortality.proofepub_ahead_of_prin

An unpredictable event?

Cardiotoxicity is common, with coronary artery disease being an important risk factor. We report the case of an acute coronary syndrome presumably induced by 5-FU, in a patient with previously unknown and asymptomatic coronary artery disease, with and estimated intermediate risk for cardiovascular events. Pre-chemotherapy risk evaluation and optimal patient care are still not standardized in this clinical scenario.publishersversionpublishe
