Análise de custo-efectividade da terapêutica de ressincronização cardíaca : avaliação da selecção baseada na dessincronia mecânica

RESUMO - A Terapêutica de Ressincronização Cardíaca (TRC) apresenta benefícios significativos na classe funcional, função ventricular, hospitalização e mortalidade. É uma técnica com custos elevados e, com os actuais métodos de selecção de doentes, a taxa de não-respondedores ronda os 30%. Objectivo: Compreender se a inclusão da dessincronia mecânica (DM) na selecção de doentes para TRC contribui para a sua relação custo-efectividade, na perspectiva do Serviço Nacional de Saúde português. Metodologia: Estudo prospectivo baseado em coortes histórias de 12 meses de dois grupos submetidos a TRC com desfibrilhador, o grupo de intervenção com doentes seleccionados com inclusão da DM (n=133) e o de controlo com selecção baseada exclusivamente nas recomendações internacionais (n=71). Reuniram-se dados clínicos e de custos nos 12 meses subsequentes à implantação, para cálculo do rácio custo-efectividade incremental (RCEI). Resultados: O grupo de intervenção apresentou uma sobrevivência de 91% e o de controlo de 93%, aos 12 meses (p=0,335). O grupo de intervenção apresentou 60 re-internamentos e o de controlo 46 re-internamentos por qualquer causa aos 12 meses (p=0,032), com RCEI=6.886,09€/re-internamento evitado. O grupo de intervenção apresentou 19 re-internamentos e o de controlo apresentou 31 re-internamentos por Insuficiência Cardíaca (IC) descompensada aos 12 meses (p<0,001), com RCEI=2.686,26€/re-internamento por IC descompensada evitado. Relativamente à melhoria da classe funcional e da fracção de ejecção não foi possível estabelecer associações com custos (p>0,05). Conclusão: É seguro afirmar que recomendar a selecção com inclusão da DM, nos hospitais com capacidade instalada, é um passo positivo na redução de custos com re-internamentos de doentes com TRC.

Introduction: digital methods and tools for historical research

As an introduction to a series of articles focused on the exploration of particular tools and/or methods to bring together digital technology and historical research, the aim of this paper is mainly to highlight and discuss in what measure those methodological approaches can contribute to improve analytical and interpretative capabilities available to historians. In a moment when the digital world present us with an ever-increasing variety of tools to perform extraction, analysis and visualization of large amounts of text, we thought it would be relevant to bring the digital closer to the vast historical academic community. More than repeating an idea of digital revolution introduced in the historical research, something recurring in the literature since the 1980s, the aim was to show the validity and usefulness of using digital tools and methods, as another set of highly relevant tools that the historians should consider. For this several case studies were used, combining the exploration of specific themes of historical knowledge and the development or discussion of digital methodologies, in order to highlight some changes and challenges that, in our opinion, are already affecting the historians' work, such as a greater focus given to interdisciplinarity and collaborative work, and a need for the form of communication of historical knowledge to become more interactive.

Lime mortars with ceramic wastes: characterization of components and their influence on the mechanical behaviour

Considering the fundamental importance of preserving the built heritage and of ensuring the good performance achieved by incorporating ceramic particles in lime mortars in ancient times, it is important to study solutions that use materials the available today, in order to produce mortars intended to repair and replace the old ones. Solutions incorporating industrial ceramic waste might be profitable for several reasons, namely for economic, environmental and technical aspects. In this paper, seven ceramic waste products collected from ceramics factories are characterized. Their mineralogy, dimensional features and pozzolanicity were determined. Three of these products, with different particle size fractions (obtained directly from milling, dust only and fragment fractions only), were selected, incorporated into air lime mortars, and their mechanical strength was determined. In the present work, evidence of mechanical efficiency, when common sand or air lime were partially replaced by ceramic wastes, was made clear, drawing attention to the sustainability of this type of mortars, hence, encouraging further research.
