Community-associated methicillin-resistant Staphylococcus aureus (CA-MRSA) in Portugal:

Methicillin-resistant Staphylococcus aureus (MRSA), a human pathogen confined to hospitals (HAMRSA) for over 30 years have been emerging worldwide in the last two decades as a leading cause of severe infections in healthy individuals in the community (CA-MRSA). Despite its clinical significance, in the beginning of our studies no information existed on the prevalence, and population structure of CA-MRSA in Portugal. Moreover, it remained to be clarified how CA-MRSA emerged in our country. In particular, it was not known if CA-MRSA emerged locally by acquisition of the staphylococcal cassette chromosome mec (SCCmec) by established methicillin-susceptible S. aureus (MSSA) in the community, if they were imported from abroad or have escaped from the hospital.(...)

Unraveling maternal and fetal genetic factors protecting from Pregnancy Associated Malaria in the mouse

Malaria is one of the most devastating diseases in the world. In Plasmodium endemic regions, pregnant women are among the most vulnerable groups. Pregnancy Associated Malaria (PAM) threatens both maternal and foetal lives. Despite differences between human and mouse placentas PAM mouse models recapitulate key pathological features of human PAM. Here we describe new PAM models of mid gestation infection in the C57BL/6 mouse.(...)

Caracterização dos padrões de mortalidade e identificação dos pontos negros de mortalidade da fauna na A21

A monitorização da mortalidade da fauna nas estradas tem vindo a receber mais atenção no decorrer dos anos sendo uma temática em que ainda existe potencial para investigação assim como de propostas para medidas de mitigação. Em Portugal, os estudos mais desenvolvidos são geralmente realizados por concessionárias como a Infraestruturas de Portugal, a Brisa entre outras. Reconhece-se a importância desta temática devido aos impactes negativos a nível ecológico e ambiental resultantes da expansão da rede viária. Um fator agravante é a fraca sensibilidade dos condutores para a presença de animais na estrada e problemas devido às caraterísticas da estrada. Existem espécies que são atraídas para a estrada para se alimentarem da vegetação envolvente ou de cadáveres de outros animais, para realizarem a termorregulação ou por simplesmente precisarem de atravessar a estrada regularmente sendo por isso mais propícias a serem atingidas por veículos. A presença de animais na estrada pode acarretar riscos de acidentes assim como perdas humanas e financeiras. Deste modo, as concessionárias implementam estudos de monitorização da mortalidade da fauna nas estradas para perceberem os locais com maior número de atropelamentos, quais as espécies mais afetadas e assim conseguirem introduzir medidas de minimização que podem ser desde vedações a passagens próprias para a fauna. O objetivo deste trabalho consistiu na caracterização dos padrões de mortalidade e identificação dos pontos negros de mortalidade da fauna na autoestrada nº 21 (A21), bem como a sua relação com o habitat envolvente. Conclui-se que os animais mais afetados são os coelhos seguindo-se as cobras e as corujas e mochos. Através do buffer do habitat envolvente e do teste estatístico de Spearman não se conseguiu provar a influência do habitat envolvente sobre a mortalidade. Finalmente, foram propostas algumas medidas de minimização para os pontos negros identificados.

Healthcare- Associated infections: An analysis of costs in a Portuguese Hospital

Hospital-acquired infections (HAIs) delay healing, prolong Hospital stay, and increase both Hospital costs and risk of death. This study aims to estimate the extra length of stay and mortality rate attributable to each of the following HAIs: wound infection (WI); bloodstream infection (BSI); urinary infections (UI); and Hospital-acquired pneumonia (HAP). The study population consisted of patients discharged in CHLC in 2014. Data was collected to identify demographic information, surgical operations, development of HAIs and its outputs. The study used regressions and a matched strategy to compare cases (infected) and controls (uninfected). The matching criteria were: age, sex, week and type of admission, number of admissions, major diagnostic category and type of discharge. When compared to matched controls, cases with HAI had a higher mortality rate and greater length of stay. WI related to hip or knee surgery, increased mortality rate by 27.27% and the length of stay by 74.97 days. WI due to colorectal surgery caused an extra mortality rate of 10.69% and an excess length of stay of 20.23 days. BSI increased Hospital stay by 28.80 days and mortality rate by 32.27%. UI caused an average additional length of stay of 19.66 days and risk of death of 12.85%. HAP resulted in an extra Hospital stay of 25.06 days and mortality rate of 24.71%. This study confirms the results of the previous literature that patients experiencing HAIs incur in an excess of mortality rates and Hospital stay, and, overall, it presents worse results comparing with other countries.

Which communication strategy should a male luxury (fashion) brand – associated with a luxury car brand – develop, in order to increase its awareness in Europe

This work project explores how a male luxury (fashion) brand (subsidiary) that is associated with a luxury car brand (parent company) should develop its communication strategy in order to increase awareness in Europe. For this purpose a quantitative research was conducted. The aim was to find out whether the company in question had low brand awareness among European luxury consumers. Hereafter, a qualitative research revealed important insights in regard to luxury communication among male luxury consumers. Both the results of the research and the recommendations of luxury experts laid the foundation for the development of a solution-oriented communication strategy. The result of the analysis crystallizes the importance of the shared heritage and the synergistic effects, of which the subsidiary should make vast use when communicating.

Regret associated with past and future messes under a maximizing mind-set

Promotions can make you happy if you get the “best” deal or miserable if you miss it. Previous research on this topic has shown that people favor products associated with a past miss to products associated with a future miss, and people in a maximizing mind-set, i.e. people who search for the best in different domains, feel more regret in a consumption domain. This research confirms that consumers prefer purchasing a product associated with a past miss (Experiments 1 and 2) and that regret levels are higher when participants come across the future miss, under the maximizing mind-set (Experiment 2). These studies add to the notion that information on regret might prompt people to make decisions towards a more optimistic outcome.
