Physical activity levels in Portuguese high school physical education

The main aim of this study was to evaluate the physical activity (PA) levels of high school Portuguese students during physical education (PE) and investigate the association of PA levels with students’ goal orientation and intrinsic motivation. Forty-six students from three high schools participated. Heart rate telemetry and pedometry were used to assess PA and the Borg rate of perceived exertion scale was used to measure perceived exertion. Thirty PE lessons were monitored. The results indicated that high school PE lessons involve low levels of PA. Students engaged in moderate to vigorous PA (MVPA) only in about one-third (29.7 minutes) of the official PE scheduled time (90 minutes) and perceived exertion as light. In general, students seemed to be positively motivated toward PE and mainly task goal orientated. Boys felt more enjoyment/interest and perceived their competence in more positive ways than girls. The number of steps and the rate of perceived exertion were associated with levels of PA measured by heart rate telemetry. Intrinsic motivation and goal orientation were not related with MVPA

Dieta mediterrânica - um desafio para a cooperação entre a cultura e a saúde nos próximos anos

A “Dieta Mediterrânica” levada à letra é um modo de viver, próprio das pessoas que vivem perto do mar, no meio das terras. Do grego - “modo de viver” e do latim - mar medi terraneum – “o mar no meio das terras”. Para compreender a Dieta Mediterrânica (DM), é pois necessário refletir sobre o facto de durante séculos, Fenícios, Gregos, Romanos, Árabes e todos os outros povos desta região, terem tido um mar interior navegável, capaz de permitir a partilha de saberes, utensílios, genes, plantas e animais. Que infuenciaram decisivamente o nosso modo de pensar e maneira de viver

Childhood Obesity Surveillance Initiative: COSI Portugal 2013

Inclui "fact sheet" distribuída na sessão de apresentação do relatório.Ficheiros do relatório e factsheets atualizados em setembro de 2015.O Childhood Obesity Surveillance Initiative (COSI)/World Health Organization Regional Office for Europe é o sistema europeu de vigilância nutricional infantil coordenado pelo Gabinete Regional Europeu da Organização Mundial da Saúde (OMS). Tem como principal objetivo criar uma rede sistemática de recolha, análise, interpretação e divulgação de informação descritiva sobre as caraterísticas do estado nutricional infantil de crianças dos 6 aos 8 anos, que se traduz num sistema de vigilância que produz dados comparáveis entre países da Europa e que permite a monitorização da obesidade infantil a cada 2-3 anos

Anticoagulantes orais diretos, antídotos e possíveis interações

Monografia realizada no âmbito da unidade de Estágio Curricular do Mestrado Integrado em Ciências Farmacêuticas, apresentada à Faculdade de Farmácia da Universidade de CoimbraA terapêutica anticoagulante foi, durante um longo período e até há pouco tempo, baseada em fármacos anticoagulantes orais antagonistas da vitamina K, que permitem tratar e prevenir riscos associados à trombose venosa, com grande expressão mundial e associada a uma elevada morbilidade e mortalidade. A varfarina e o acenocumarol são ainda fármacos bastante utilizados, dos quais se conhece a eficácia e precauções a ter para uma terapêutica eficaz. No entanto, a margem terapêutica estreita, variedade e quantidade de interações e a necessidade de monitorização periódica desta terapêutica revelava-se inconveniente e até uma ameaça para a sua plena eficácia. Na sequência destas desvantagens surgiram recentemente opções revolucionárias na terapêutica anticoagulante. As novas moléculas aprovadas e atualmente comercializadas em Portugal são o dabigatrano, rivaroxabano e apixabano. Estes fármacos, denominados de anticoagulantes diretos, vieram beneficiar o doente ao proporcionar uma terapêutica eficaz que não o obriga a monitorizações periódicas. Apresentam um início de ação mais rápido e não estão sujeitos a um número de interações tão grande quanto os antagonistas da vitamina K. A sua maior desvantagem já está a ser atualmente corrigida uma vez que já se encontra disponível o antídoto para o dabigatrano, o idarucizumab, estando em fase de aprovação o andexanet alfa para o rivaroxabano e apixabano. Para além destes, a aripazina é um antidoto geral de anticoagulantes que está em estudos clínicos. Também os antídotos específicos dos novos anticoagulantes apresentam a vantagem em relação à vitamina K por não terem atividade protrombínica.Anticoagulant therapy was for a long time and until recently, based on vitamin K antagonist oral anticoagulant drugs, which treat and prevent venous thrombosis associated risks, with a great expression in world society and a high morbidity and mortality associated. Warfarin and acenocoumarol were and still are widely used drugs, which are known for its efficacy and precautions to take for an effective therapy. However, the narrow therapeutic window, variety and quantity of interactions and the need for periodic monitoring, reveals inconvenient and even a threat to the full effectiveness of the therapy. In the result of the disadvantages, recently have arisen revolutionary options in the anticoagulant therapy. The new approved and currently marketed molecules in Portugal are dabigatran, rivaroxaban and apixaban. These drugs are direct anticoagulants and are used to benefit the patient by providing an effective therapy that does not require periodic monitoring. They have a faster onset of action and are not subject to a number of interactions as large as the vitamin K antagonists. The biggest drawback is being corrected since, there is now available the antidote to dabigatran, the idarucizumab and is on the approval stage the andexanet alfa for rivaroxaban and apixabano. In addition to these, the aripazin is a general anticoagulant antidote that is on clinical studies. Also the specific antidotes for the new anticoagulants have the advantage of not showing prothrombotic activity compared to the vitamin K

Portuguese Food and Nutrition Action Plan

Background and objectives: In Portugal there is a coexis- tence of high prevalence of obesity with high levels of food in- security. Food insecurity may lead to the increasing of health inequalities, namely by an unequal distribution of obesity and other diet-related chronic diseases through the most vulne- rable groups. This situation prompted the Portuguese Health Ministry to define the National Program of Healthy Eating as a priority program, which aims to improve the population ́s nutritional status by promoting availability and physical/eco- nomic access to healthy foods thus creating conditions for all citizens to valorize, consume and integrate them into their daily routines.Methods: Launched on March 2012, after consultation with partners and civil society, this is the first formal food and nu- trition action plan in Portugal. Until that date, Portugal did not have a formal and integrated strategy.Results: The strategy determined five objectives: (1) increa- se knowledge about food consumption and nutritional sta- tus of the population, its determinants and consequences (2) improve the consumer's knowledge to make them able to do more informed decisions (3) improve the availability of certain types of foods, particularly in schools, workplaces and other public institutions (4) identify and promote integrated and crossed-actions with other society sectors that encourage the consumption of healthy foods and (5) improve the qualifica- tion of professionals who can influence knowledge, attitudes and behaviours in the food field. This strategy aims to combine economic growth with improving the nutrition situation and intends to integrate the local health regions and municipalities in a solid and structured nationally program, paying special at- tention to health inequalities.Conclusions: This program follows the recent recommen- dations of the WHO and EC, and pretends to be a multisecto- rial program, involving stakeholders on healthy eating promo- tion, addressing the current challenges of the double burden of malnutrition and the health inequalities

Adequação dos exames de radiologia solicitados por um departamento de emergência: um estudo retrospetivo

Imaging tests are essential for diagnosis in the emergency context and convey clinical information that is essential to assess the appropriateness of the tests and improve their interpretation. Therefore, we aimed to analyze the imaging tests requested by the Emergency Department in a district hospital.info:eu-repo/semantics/publishedVersio
