    Uma alimentação equilibrada e saudável na infância é determinante para o desenvolvimento físico e psíquico da criança, e é sobretudo nesta fase que se desenvolvem os gostos e preferências alimentares, que determinação as escolhas, e que terão, consequentemente, uma influência notória na saúde. Em Portugal, de acordo com o Inquérito Alimentar Nacional e de Atividade Física, em 2017, as crianças (< 10 anos) tinham uma ingestão média de açúcares livres de 41,8 g/dia, de gordura saturada de 21,9 g/dia e de sal de 5,3 g/dia. Em 2020, foi determinado o teor de gordura e de sal de 24 tipos de produtos de pastelaria (pães de leite sem recheio, com recheio e/ou com pepitas; croissants com e sem recheio). Os teores de gordura total variaram entre 9,22 e 29,4 g/100 g e os teores de sal variaram entre 0,537 e 1,17 g/100 g. Todos os produtos analisados encontram- -se acima da meta fixada pela EIPAS (0,3 g de sal por 100 g). Conclui-se que é necessário desenvolver estratégias para a reformulação progressiva destes alimentos e assim possibilitar a oferta de produtos com um perfil nutricional mais adequado às necessidades em saúde pública.A balanced and healthy diet in childhood is crucial for the child's physical and mental development, and it is mainly at this stage that food taste and preferences are developed, which will determine choices and will have a notable influence on health. In Portugal, according to the National Food and Physical Activity Survey, in 2017, children (< 10 years) had an average intake of free sugars of 41.8 g/day, of saturated fat of 21.9 g/day and 5.3 g/day of salt. In 2020, the fat and salt content of 24 types of pastry products (non-filled and/or filled sweet breads; croissants with and without filling) were determined. The total fat contents varied between 9.22 and 29.4 g/100 g, and the salt contents varied between 0.537 and 1.17 g/100 g. All the analyzed products are above the target set by EIPAS (0.3 g of salt per 100 g). In summary, it is necessary to develop strategies for the progressive reformulation of these foods and thus enable to offer products with a nutritional profile more suited to public health needs.info:eu-repo/semantics/publishedVersio

    High frequency of Fredrickson's phenotypes IV and IIb in Brazilians infected by human immunodeficiency virus

    BACKGROUND: Human immunodeficiency virus (HIV) infection is very prevalent in Brazil. HIV therapy has been recently associated with coronary heart disease (CHD). Dyslipidemia is a major risk factor for CHD that is frequently described in HIV positive patients, but very few studies have been conducted in Brazilian patients evaluating their lipid profiles. METHODS: In the present work, we evaluated the frequency and severity of dyslipidemia in 257 Brazilian HIV positive patients. Two hundred and thirty-eight (93%) were submitted to antiretroviral therapy (224 treated with protease inhibitors plus nucleoside reverse transcriptase inhibitors, 14 treated only with the latter, 12 naive and 7 had no records of treatment). The average time on drug treatment with antiretroviral therapy was 20 months. None of the patients was under lipid lowering drugs. Cholesterol, triglyceride, phospholipid and free fatty acids were determined by enzymatic colorimetric methods. Lipoprotein profile was estimated by the Friedewald formula and Fredrickson's phenotyping was obtained by serum electrophoresis on agarose. Apolipoprotein B and AI and lipoprotein "a" were measured by nephelometry. RESULTS: The Fredrickson phenotypes were: type IIb (51%), IV (41%), IIa (7%). In addition one patient was type III and another type V. Thirty-three percent of all HIV+ patients presented serum cholesterol levels ≥ 200 mg/dL, 61% LDL-cholesterol ≥ 100 mg/dL, 65% HDL-cholesterol below 40 mg/dL, 46% triglycerides ≥ 150 mg/dL and 10% have all these parameters above the limits. Eighty-six percent of patients had cholesterol/HDL-cholesterol ratio ≥ 3.5, 22% increased lipoprotein "a", 79% increased free fatty acids and 9% increased phospholipids. The treatment with protease inhibitors plus nucleoside reverse transcriptase inhibitors increased the levels of cholesterol and triglycerides in these patients when compared with naïve patients. The HDL-cholesterol (p = 0.01) and apolipoprotein A1 (p = 0.02) levels were inversely correlated with the time of protease inhibitor therapy while total cholesterol levels had a trend to correlate with antiretroviral therapy (p = 0.09). CONCLUSION: The highly varied and prevalent types of dyslipidemia found in Brazilian HIV positive patients on antiretroviral therapies indicate the urgent need for their early diagnosis, the identification of the risk factors for CHD and, when needed, the prompt intervention on their lifestyle and/or with drug treatment

    O artigo explora dimensões geopolíticas da toponímia, registradas em documentos cartográficos, desde as reformas empreendidas pelo consulado pombalino em meados do século XVIII, até às primeiras décadas do século XIX, em meio ao processo de afirmação do Estado imperial pós-colonial.This paper explores the geopolitical dimensions of toponymy as registered in cartographic documents dating from the reforms pushed through by the consulate of Marquis of Pombal in the mid 18th century to the early decades of the 19th century, as the post-colonial imperial State established itself

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

    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.
