    Trabalho de projecto apresentado para cumprimento dos requisitos necessários à obtenção do grau de Mestre em Comunicação de CiênciaÉ possível comunicar a complexidade das disciplinas científicas e provocar o debate sobre ciência de uma forma atractiva? É possível fazê-lo e, ao mesmo tempo, criar um gosto pela sua discussão junto de um público jovem? E se a essas preposições adicionássemos acompanhamento musical? O projecto “Os Sons da Ciência” começa por apresentar duas certezas: a tecnologia tem multiplicado infinitamente as possibilidades que temos para ouvir música; e um pouco por todo o lado, estrelas bem conhecidas do mundo da música interpretam canções e contam histórias que se referem a temas, conceitos, visões, reflexos ou atitudes perante temas científicos. Partindo destas premissas, montámos um projecto de comunicação de ciência que pretende provocar diálogo, envolvimento e participação de vários públicos-alvo. Insere-se na filosofia do paradigma de comunicação Science and Society. Pretendemos, assim, trabalhar em torno de temas musicais temas já existentes onde a ciência se manifesta de alguma forma, dando-lhes nova roupagem. Cientistas, comunicadores e músicos portugueses serão convidados a trabalhar a partir de doze temas bem conhecidos do público – de David Bowie a Gilberto Gil, de Björk a Fausto Bordalo Dias – e dar-lhes nova direcção. Dos músicos espera-se que reinterpretem, segundo o seu estilo, um tema que lhes seja atribuído. Dos investigadores/comunicadores, que produzam um texto a partir desse tema musical, que deverá reincidir sobre a ciência presente nessa música. Desta constante interacção, espera-se que nasçam formas originais de comunhão com o público. Parece-nos evidente que, numa sociedade democrática, é fundamental partilhar com os cidadãos conteúdos sobre ciência e tecnologia cada vez mais presente no seu quotidiano. Mas também nos parece claro que esse esforço de partilha e debate desses temas deve (também) procurar meios e métodos informais, bem próximos das paixões humanas, para que seja realmente eficaz

    Esta pesquisa teve como objetivos identificar as representações sociais de mulheres sobre o câncer do colo do útero, e descrever a relação dessas representações sociais para o cuidado preventivo. A abordagem utilizada foi do tipo qualitativo-exploratório, adotando a teoria das representações sociais como suporte teórico-conceitual. Duas técnicas de coleta foram utilizadas para obtenção dos dados: a livre associação de palavras e a entrevista semidirigida com perguntas abertas. Para a interpretação dos dados foi utilizada a técnica de análise temática. A pesquisa teve como resultado duas unidades temáticas: câncer cérvico-uterino - uma ferida tratável e o preventivo - o fazer por temer. Observou-se que as mulheres temem muito o câncer cérvico-uterino e, por esse motivo, admitem a importância da realização do exame preventivo, considerando-o como um ato de cuidado com a própria saúde.Esta investigación tiene como objetivo identificar las identificar las representaciones sociales de mujeres sobre el cáncer del cuello uterino; y describir la relación de esas representaciones sociales para el cuidado preventivo. El abordaje utilizado fue cualitativa - exploratoria, adoptando como soporte teórico conceptual la teoría de las representaciones sociales. Para obtención de los datos se utilizaron tres técnicas de recolección: la asociación libre de palabras, la entrevista semi dirigida con preguntas abiertas y la observación libre. Para la interpretación de esos datos, fue utilizada la técnica de análisis de contenido temático. La investigación tuvo como resultado de las unidades temáticas: cáncer cérvico-uterino: una herida tratable y el preventivo: El hacer por temer. Durante toda la investigación, se observo que las mujeres temen mucho tener cáncer cérvico - uterino, y por ese motivo, admiten la importancia de la realización del examen preventivo y lo consideran como un acto de cuidado con la propia salud.This research aims to identify women's social representations of women regarding cervical cancer and describe the relationship of these social representations with preventive care. The study used a qualitative-exploratory approach, with the theory of social representations as the theoretical-conceptual support. Data collection was performed using two techniques: the free association of words and the semi-directed interview with open questions. The thematic analysis technique was used for data interpretation. The research resulted in two thematic units: cervical cancer: an early treatable wound and the screening test: taking because of fearing. It was observed that women have great fear of having cervical cancer and, therefore, recognize the importance of the screening test and see it as an act of self-care towards their health

    Introduction: Compared to bare-metal stents (BMS), drug-eluting stents reduce stent restenosis and improve subsequent revascularization rates. The impact on patients’ survival has been the subject of debate. Objective: To assess the long-term (10-year) survival of patients undergoing percutaneous coronary intervention (PCI) with first-generation sirolimus-eluting stents (SES) in comparison with BMS. Methods: In a single-center registry, 600 consecutive patients who underwent successful PCI with SES between April 2002 and February 2003 were compared to 594 patients who underwent PCI with BMS between January 2002 and April 2002, just before the introduction of SES. Clinical and procedural data were collected at the time of intervention and 10-year survival status was assessed via the national life status database. Results: All baseline characteristics were similar between groups except for smaller stent diameter (2.84±0.38 vs. 3.19±0.49 mm; p<0.001), greater stent length (18.50±8.2 vs. 15.96±6.10 mm; p<0.001) and higher number of stents per patient (1.95 vs. 1.46, p<0.001) in the SES group. Overall five- and 10-year all-cause mortality was 9.6% (n=110) and 22.7% (n=272), respectively. The adjusted HR for 10-year mortality in patients undergoing PCI with SES was 0.74 (95% CI 0.58-0.94; p=0.013), corresponding to a relative risk reduction of 19.8%. Other than PCI with BMS, older age, chronic kidney disease, chronic obstructive pulmonary disease and lower ejection fraction were independent predictors of 10-year mortality. Conclusion: To date, this is the longest follow-up study ever showing a potential survival benefit of first-generation sirolimus-eluting stents versus bare-metal stents, supporting prior observations on their sustained efficacy and safety relative to contemporary BMS.publishersversionpublishe

    Funding Information: The authors wish to acknowledge the invaluable contributions of Paulo Leal regarding data acquisition and management, and John Henderson for statistical consultancy. Publisher Copyright: © 2021 Sociedade Portuguesa de CardiologiaIntroduction and Objectives: Use of invasive physiological assessment in patients with coronary artery disease varies widely and is perceived to be low. We aimed to examine adoption rates as well as patterns and determinants of use in an unselected population undergoing invasive coronary angiography over a long time frame. Methods: We retrospectively determined the per-procedure prevalence of physiological assessment in 40 821 coronary cases performed between 2007 and 2018 in two large-volume centers. Adoption was examined according to procedure type and patient- and operator-related variables. Its association with relevant scientific landmarks, such as the release of clinical trial results and practice guidelines, was also assessed. Results: Overall adoption was low, ranging from 0.6% in patients undergoing invasive coronary angiography due to underlying valve disease, to 6% in the setting of stable coronary artery disease (CAD); it was 3.1% in patients sustaining an acute coronary syndrome. Of scientific landmarks, FAME 1, the long-term results of FAME 2 and the 2014 European myocardial revascularization guidelines were associated with changes in practice. Publication of instantaneous wave-free ratio (iFR) trials had no influence on adoption rates, except for a higher proportion of iFR use. In 42.9% of stable CAD patients undergoing percutaneous coronary intervention there was no objective non-invasive evidence of ischemia, nor was physiological assessment performed. Younger operator age (4.5% vs. 4.0% vs. 0.9% for ages 55 years, respectively; p<0.001) and later time of procedure during the day (2.9% between 6 and 8 p.m. vs. 4.4% at other times) were independent correlates of use of invasive physiology. Conclusions: Our study confirms the low use of invasive physiology in routine practice. The availability of resting indices did not increase adoption. Strategies are warranted to promote guideline implementation and to improve patient care and clinical outcomes.publishersversionpublishe

    © 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

    Abandono do tratamento de tuberculose em co-infectados TB/HIV

    Get PDF
    Este estudo objetivou analisar os motivos que levam os pacientes coinfectados TB/HIV a abandonar o tratamento da TB e conhecer a conduta da equipe de saúde frente a esse abandono. A abordagem foi qualitativa. Utilizou-se a entrevista semiestruturada, aplicada a quarenta e cinco profissionais que atuam em uma Unidade de Referência no Pará. Após análise temática, foram construídas duas unidades: fatores relacionados aos doentes que dificultam adesão ao tratamento da TB; e fatores relacionados ao serviço que contribuem para o abandono. Mostrou-se, com relação aos pacientes, que a baixa condição socioeconômica foi o fator mais frequente que propicia o abandono. Também efeitos adversos dos medicamentos, uso de drogas lícitas, e pouca motivação pessoal facilitam esse desfecho. Quanto ao Serviço, as questões relacionadas à estrutura física, organização do processo de trabalho e acesso mostraram-se relevantes para não adesão. Os resultados apontam para a necessidade de alterar as práticas desenvolvidas nos Serviços

    No full text
    Context: Endo-PTC are used during endodontic treatment; however, until now no study evaluated the cleaning of dentin walls after use of different Endo-PTC formulations. Aims: The aim of this study was to assess qualitatively, by means of scanning electron microscopy (SEM) images, the cleaning of dentin walls of root canals after chemomechanical preparation (CMP) using Endo-PTC cream and Endo-PTC light associated to 2.5% sodium hypochlorite and 17% ethylenediamine tetraacetate (EDTA). Materials and Methods: Forty single-rooted human maxillary central incisors with straight canals and fully formed apex were selected. The specimens were randomly divided into four groups depending on the type of Endo-PTC and the final rinse with 17% EDTA. After CMP, all specimens were sectioned and processed for observation of the apical thirds by using SEM. Three calibrated evaluators attributed scores to each specimen. Statistical Analysis Used: The differences between irrigation protocols were analyzed with Kruskal-Wallis test followed by Bonferroni adjustment for multiple comparisons. The significance level was set at α = 0.05. Results: The use of Endo-PTC cream or Endo-PTC light did not influence the smear-layer (SL) removal (P > 0.05). When EDTA were used, it was obtained the best cleaning results with no significant difference between the substances (P < 0.05). Conclusions: It can be concluded that EDTA is essential to promote SL removal which was not affected by the type of Endo-PTC formulation
