- Trends of case-fatality rate by acute coronary syndrome in Portugal: Impact of a fast track to the coronary unitPublication . Abreu, D.; Pinto, F.J.; Matias-Dias, C.; Sousa, P.Introduction: Efforts were made to improve management of coronary disease as the fast-track system to the Coronary Unit. We aim to analyse case-fatality rates by acute coronary syndrome in Portugal from 2000 to 2016, mainly the impact of the fast-track system and the proportion of patients that activate the fast-track system. Methods: We analysed monthly acute coronary syndrome case-fatality before and after the implementation of the fast-track system in 2007. Impact of the system was assessed through regression models for interrupted time-series. We calculated annual proportion of fast-track system admissions. Results: After 2007 case-fatality by acute coronary syndrome decreased (β=-1.27, p-value < 0.01). The estimates obtained for ST Elevation Myocardial Infarction suggest a reduction of nearly 86 monthly deaths prevented after 2007. The highest percentage of patients admitted through the fast-track system was 35%. Conclusions: Our results suggest fast-track system may have contributed to a decline in acute coronary syndrome case-fatality. However, more than half of patients were not admitted through the system. This should encourage health authorities to make efforts to ensure compliance.
- Microbiological characterization of different formulations of alheiras (fermented sausages)Publication . Silva, Julieta; Barbosa, Joana; Albano, Helena; Sequeira, Maria; Pinto, Ana; Costa Bonito, Conceição; Saraiva, Margarida; Teixeira, PaulaDifferent ingredients in old recipes are becoming popular and the traditional alheira did not escape to this new trend. The objective of this preliminary study was to characterize microbiologically nine different formulations of alheira from five producers. In this sense, isolates obtained were characterized through different phenotypic and biochemical tests. Their susceptibility to different antimicrobials and the presence of virulence factors was also investigated. Lactic acid bacteria were the predominant microbiota, but pathogenic bacteria as coagulase-positive staphylococci, Listeria monocytogenes and Salmonella spp. as well as indicator organisms were also found. Several virulence factors were produced among the different groups of isolates, with a high incidence of isolates producing β-haemolysis. Along with their potential pathogenic activity, also several antimicrobial resistances were found being the majority of isolates classified as multi-resistant. At our knowledge, this is the first study with these new formulations of alheira. A higher number of products must be analyzed, but we believe that results obtained in this study should help to alert consumers for the need of safe cooking time/temperatures of these products.
