    INTRODUCTION: Contralateral carotid occlusion (CCO) is considered a high-risk condition for patients undergoing carotid artery endarterectomy (CEA). Patients with a CCO may be intolerant to carotid cross-clamping during CEA, thus prone to postoperative adverse neurological outcomes. Patients with CCO may also have a higher burden of atherosclerotic disease, leading to a higher rate of cardiovascular events. METHODS: A Medline search was performed in order to identify publications focused on the impact of CCO on outcomes after CEA. RESULTS: Patients with CCO present a higher incidence of intolerance to carotid cross-clamping. The rates of shunt use are higher in patients with CCO. In the postoperative period, patients with CCO show a higher rate of stroke. Evidence regarding the effect of CCO on long-term outcomes remains controversial, with most studies reporting a lack of association between CCO and adverse long-term outcomes after CEA. CONCLUSION: Patients with CCO have an increased risk of postoperative adverse outcomes. The best strategy for this group of patients should be based on a case-by-case approach

    Microglia have been increasingly implicated in neurodegenerative diseases (NDs), and specific disease associated microglia (DAM) profiles have been defined for several of these NDs. Yet, the microglial profile in Machado–Joseph disease (MJD) remains unexplored. Here, we characterized the profile of microglia in the CMVMJD135 mouse model of MJD. This characterization was performed using primary microglial cultures and microglial cells obtained from disease-relevant brain regions of neonatal and adult CMVMJD135 mice, respectively. Machine learning models were implemented to identify potential clusters of microglia based on their morphological features, and an RNA-sequencing analysis was performed to identify molecular perturbations and potential therapeutic targets. Our findings reveal morphological alterations that point to an increased activation state of microglia in CMVMJD135 mice and a disease-specific transcriptional profile of MJD microglia, encompassing a total of 101 differentially expressed genes, with enrichment in molecular pathways related to oxidative stress, immune response, cell proliferation, cell death, and lipid metabolism. Overall, these results allowed us to define the cellular and molecular profile of MJD-associated microglia and to identify genes and pathways that might represent potential therapeutic targets for this disorder.This work was supported by Fundação para a Ciência e a Tecnologia (FCT) (PTDC/NEUNMC/3648/2014) and COMPETE-FEDER (POCI-01-0145-FEDER-016818).

    Actas do Colóquio Internacional Psicologia e Educação. ISPS Instituto Universitário. Junho 2015As sociedades de hoje e consequentemente as comunidades educativas deparam-se hoje em dia com grandes desafios, alguns dos quais decorrentes da diversidade e da heterogeneidade dos diferentes intervenientes e contextos aos quais é necessário dar respostas adequadas. Deste modo, é importante refletir sobre esta(s) nova(s) realidade(s) e investigar sobre as suas caraterísticas de modo a encontrar respostas adequadas aos desafios que esta diversidade nos coloca e exige. Este livro pretende dar mais um contributo para esta reflexão ao reunir um conjunto de trabalhos que foram apresentados no âmbito do 13º Colóquio Internacional de Psicologia e Educação organizado pelo Departamento de Psicologia da Educação e pelo Centro de Investigação em Educação do ISPA-Instituto Universitário, entre 25 e 27 de Junho de 2015. Neste colóquio, investigadores e profissionais de diferentes áreas refletiram sobre estas mudanças sociais, culturais e científicas e sobre o papel da Psicologia e da Educação para a compreensão e procura de respostas perante estes novos desafios. A variedade de temas aqui reunidos reflete, de algum modo, parte da diversidade com que os profissionais da Psicologia e da Educação se deparam no dia-a-dia da sua intervenção. Não só se contemplam problemáticas em contextos mais formais como a escola ou as instituições educativas, como também em contexto familiar, evidenciando a importância cada vez maior do papel que se atribui às famílias enquanto parceiros no processo educativo. Os temas contemplados abrangem múltiplas problemáticas atuais que colocam desafios constantes aos profissionais da Psicologia da Educação na sua prática, e que se prendem não só com aspetos ligados à disrupção e bullying, ou respostas a crianças com necessidades educativas especiais, mas também a aspetos transversais ao processo educativo e de aprendizagem de todos os alunos, como a sua motivação ou o papel das emoções.info:eu-repo/semantics/publishedVersio

Methods: Multicenter, prospective, observational study of a cohort of preterm infants born with gestational age (GA) < 32 weeks or birth weight < 1500 g in eight Portuguese neonatal intensive care units. All demographic, clinical, and laboratory data from the first week of life were collected. Univariate logistic regression was used to assess risk factors for ROP and then multivariate regression was performed. Results: A total of 455 infants were included in the study. The median GA was 29.6 weeks, and the median birth weight was 1295 g. One hundred and seventy-two infants (37.8%) developed ROP. Median values of erythrocytes (p < 0.001), hemoglobin (p < 0.001), hematocrit (p < 0.001), mean corpuscular hemoglobin concentration (p < 0.001), lymphocytes (p = 0.035), and platelets (p = 0.003) of the group of infants diagnosed with ROP any stage were lower than those without ROP. Mean corpuscular volume (MCV) (p = 0.044), red blood cell distribution width (RDW) (p < 0.001), erythroblasts (p < 0.001), neutrophils (p = 0.030), neutrophils-lymphocytes ratio (p = 0.028), and basophils (p = 0.003) were higher in the ROP group. Higher values of MCV, erythroblasts, and basophils remained significantly associated with ROP after multivariate regression. Conclusion: In our cohort, the increase in erythroblasts, MCV, and basophils in the first week of life was significantly and independently associated with the development of ROP. These CBC parameters may be early predictive biomarkers for ROP.Open access funding provided by FCT|FCCN (b-on).

    SARS-CoV-2 introductions and early dynamics of the epidemic in Portugal

    Get PDF
    Genomic surveillance of SARS-CoV-2 in Portugal was rapidly implemented by the National Institute of Health in the early stages of the COVID-19 epidemic, in collaboration with more than 50 laboratories distributed nationwide. Methods By applying recent phylodynamic models that allow integration of individual-based travel history, we reconstructed and characterized the spatio-temporal dynamics of SARSCoV-2 introductions and early dissemination in Portugal. Results We detected at least 277 independent SARS-CoV-2 introductions, mostly from European countries (namely the United Kingdom, Spain, France, Italy, and Switzerland), which were consistent with the countries with the highest connectivity with Portugal. Although most introductions were estimated to have occurred during early March 2020, it is likely that SARS-CoV-2 was silently circulating in Portugal throughout February, before the first cases were confirmed. Conclusions Here we conclude that the earlier implementation of measures could have minimized the number of introductions and subsequent virus expansion in Portugal. This study lays the foundation for genomic epidemiology of SARS-CoV-2 in Portugal, and highlights the need for systematic and geographically-representative genomic surveillance.We gratefully acknowledge to Sara Hill and Nuno Faria (University of Oxford) and Joshua Quick and Nick Loman (University of Birmingham) for kindly providing us with the initial sets of Artic Network primers for NGS; Rafael Mamede (MRamirez team, IMM, Lisbon) for developing and sharing a bioinformatics script for sequence curation (https://github.com/rfm-targa/BioinfUtils); Philippe Lemey (KU Leuven) for providing guidance on the implementation of the phylodynamic models; Joshua L.
