Atividade física e Saúde Pública : políticas e estratégias de ação intersectorial na promoção de health-enhancing physical activity (HEPA) em Portugal

RESUMO - INTRODUÇÃO: A promoção de health-enhancing physical activity (HEPA), entendida como atividade física para a saúde, revela-se um dos aspectos fulcrais do trabalho de ação intersectorial da saúde pública e um dos principais desafios atuais no combate a esta pandemia da inatividade física de consequências na saúde, económicas, ambientais e sociais. A inatividade física está identificada como sendo um dos fatores de risco que contribui largamente para a mortalidade global. Análises às abordagens políticas de promoção da atividade física para a saúde são importantes instrumentos de sistematização da informação relacionada com o estudo deste problema. OBJETIVOS: É objetivo deste estudo analisar políticas e estratégias de ação intersectorial na promoção da atividade física para a saúde em Portugal. Em específico, elencar e analisar: 1) principais políticas e estratégias atuais dos diferentes sectores; 2) consideração de qual é o papel do sector da saúde no assunto; 3) fatores-chave e critérios de sucesso para a implementação de políticas de promoção de HEPA. METODOLOGIA: Estudo qualitativo, descritivo e transversal, por meio de entrevistas semiestruturadas e abertas pelos sectores da saúde, educação, desporto, transportes/planeamento urbano e ação social; análise documental, relativamente aos últimos 3 anos, com análise de conteúdo quanto aos critérios de sucesso presentes. RESULTADOS: Foram encontradas várias categorias nas dimensões macroambiente, microambiente e individual dos determinantes da atividade física no trabalho dos diferentes sectores; o sector da saúde não foi habitualmente considerado como devendo proporcionar administração para a ação intersectorial neste domínio; foram identificados os critérios: com menor expressão no material analisado, aos quais é atribuída maior importância e aqueles com menor aplicabilidade nos documentos analisados. CONCLUSÕES: Não podemos afirmar que exista uma abordagem política/estratégica integrada de abrangência nacional, operacional, no que respeita à promoção da atividade física para a saúde. São limitadas as conclusões pelas características inerentes ao tipo de estudo desenhado, no entanto, pensamos ter contribuído para descrever as principais políticas e estratégias de ação intersectorial na promoção de HEPA em Portugal. Estudos mais abrangentes em termos de níveis de governação, sectores envolvidos e período temporal deverão ser desenvolvidos de forma a potenciar o desenvolvimento da atividade física e saúde pública.

Structuring for glocalization

Globalization and localization seem to be opposite concepts – a thesis and its antithesis. Nonetheless, managers seem to be able to handle the paradox posed by these two contradicting tensions by enacting, via action, a synthesis that allows for the co-presence of a high level of global integration and local adaptation (instead of a compromise between both), which has been labeled glocalization. We discuss how the concept of improvisation allows this synthesis by developing the two poles that ground it, namely ‘glocal’ strategy and ‘glocal’ organization. Global advantage requires a dialectical capability that organizations rarely achieve, and the importance of which orthodox management theory rarely recognizes.

Exposição a ozono em cabinas de avião

RESUMO - O ozono é o principal componente da poluição fotoquímica do ar. Como agente irritante do aparelho respiratório, os seus efeitos sobre a saúde caracterizam-se, essencialmente, por tosse, dispneia, desconforto torácico e alterações da função pulmonar, encontrando-se também associadas à exposição ambiental a O3 tanto uma maior frequência e gravidade de crises de asma como a ocorrência de quadros clínicos de irritação conjuntival. É sobretudo a partir dos anos 50, com a descoberta de concentrações elevadas de ozono em ambientes de trabalho respeitantes à actividade de soldadura «a arco», que aquele gás passa a ser encarado como factor profissional de risco. No início dos anos 60 surgem os primeiros estudos de exposição a O3 em cabinas de avião, suscitados pela ocorrência, em tripulantes e passageiros, de queixas clínicas de irritação do tracto respiratório. Esta sintomatologia era, até então, atribuída à acção de outros factores, designadamente o sistema de ventilação e o baixo teor de humidade do ar. Posteriormente, alguns estudos revelaram que, em voos comerciais subsónicos, os teores elevados de O3 observados no interior das cabinas poderiam ser provocados pela sua insuficiente destruição nos sistemas de entrada de ar.O presente estudo, efectuado em voos de longo curso realizados em aeronaves Airbus A340-300 numa única rota comercial, teve por objectivo avaliar a exposição a ozono no ar interior em cabina de avião. Os teores médios de concentração de ozono observados foram inferiores aos valores susceptíveis de provocarem efeitos adversos sobre o aparelho respiratório. Como valor máximo instantâneo, foi atingida a concentração de 152 ppb. Adicionalmente, foi constatada a influência das estações do ano nos teores de O3. O conjunto dos resultados obtidos permite concluir que as concentrações de ozono no ar interior nas cabinas de avião estudadas são inferiores às correspondentes concentrações máximas admissíveis, tendo, em todos os voos, sido observado o cumprimento da norma da FAA respeitante à protecção da exposição ao ozono em cabinas de aeronaves de aviação comercial.

Assessing the efficacy of the Mental Health Gap Action Programme (mhGAP) training for non-specialized health workers in Ethiopia

RESUMO: A OMS lançou em 2008, o Programa de Acção do Gap em Saúde Mental (mhGAP) para suprir a falta de cuidados, especialmente em países de rendimento baixo e médio, para as pessoas que sofrem de perturbações mentais, neurológicas e de uso de substâncias (MNS). Um componente crucial do mhGAP é representado pelo esforço no sentido da integração da saúde mental nos cuidados de saúde primários. Na Etiópia, o mhGAP foi monitorizado durante 3 anos, graças a um projeto de demonstração implementado em clínicas selecionadas em quatro regiões do país. A fase de demonstração de mhGAP na Etiópia traduziu-se principalmente na formação de profissionais de saúde não especializados, fornecendo-lhes orientação e supervisão apoiada para a utilização de medicamentos psicotrópicos essenciais e na coordenação com o Ministério Etíope Federal da Saúde, Hospital Amanuel de Saúde Mental e as Secretarias Regionais de Saúde ( RHBs ). O presente trabalho investigou a eficácia do pacote de formação mhGAP através de uma análise das pontuações dos participantes no pré- e pós-testes. A análise estatística mostrou - com uma exceção - que a melhoria dos formandos é estatisticamente significativa, o que sugere que os conhecimentos dos participantes é melhorada na fase de pós-teste. A eficácia do pacote de formação mhGAP para profissionais de saúde não especializados é uma evidência promissora de que os mesmos podem ser treinados com sucesso para realizar um pacote básico de intervenções para a prestação de cuidados e tratamento para pessoas com perturbações mentais, neurológicas e de uso de substâncias. Este trabalho destaca, também, várias limitações não apenas inerentes ao próprio projecto de investigação tais como o número limitado de respostas que foram analisadas e a falta de dados de uma das quatro regiões onde mhGAP foi testado na Etiópia. As principais limitações decorrem de facto da abordagem global limitar as intervenções de saúde mental ao programa de formação e supervisão dos trabalhadores de cuidados de saúde primários . Este processo só será bem sucedido se, juntamente com outras intervenções - que vão desde o desenvolvimento de currículos para o desenvolvimento de uma legislação de saúde mental -, fôr incluído numa estratégia mais abrangente para a reforma da saúde mental e desafiar o status quo.-----------ABSTRACT:In 2008, WHO launched the Mental Health Gap Action Programme (mhGAP) to address the lack of care, especially in low- and middle- income countries, for people living with mental, neurological and substance use (MNS) disorders. A crucial component of mhGAP is represented by the endeavor towards integration of mental health into primary health care. In Ethiopia, mhGAP has been piloted for 3 years thanks to a demonstration project implemented in selected clinics in 4 regions of the country. The demonstration phase of mhGAP in Ethiopia has mainly translated into training of non-specialized health workers, providing them with mentorship and supportive supervision, availing essential psychotropic medications and coordinating with the Ethiopian Federal Ministry of Health, Amanuel Mental Health Hospital and the Regional Health Bureaus (RHBs). The present paper investigated the efficacy of the mhGAP training package through an analysis of the participants’ scores at pre-test and post-test. The statistical analysis showed - with one exception - that the improvement of trainees is statistically significant, therefore suggesting that the knowledge of participants is improved in the post-test phase. The efficacy of the mhGAP training package on non-specialized health workers is promising evidence that non-specialized health-care providers can be successfully trained to deliver a basic package of interventions for providing care and treatment for people with mental, neurological and substance use disorders. However, this paper also highlights several limitations, which are not only inherent to the research itself, such as the limited number of scores that was analyzed, or the lack of data from one of the four regions where mhGAP has been piloted in Ethiopia; major limitations occur in fact in the overall approach of confining mental health interventions to training and supervising primary health care workers. This process will only be successful if coupled with other interventions – ranging from curricula development to development of a mental health legislation - and if it is included in a more comprehensive strategy to reform mental health and challenge the status quo.

Achieving better service level results, through improvements in procedures

This project aims to prepare Worten Empresas (WE) fulfilling the increasing market demand through process changings, focusing on the Portuguese market, particularly on internal B2B clients1. Several methods were used to measure the current service level provided - process mapping, resources assessment, benchmark and a survey. The results were then used to compare against service level actually desired by WE’s customer, and then to identify the performance gaps in response times and quality of the follow-up during the sales process. To bridge the identified gaps, both a set of recommendations and an implementation plan were suggested to improve and monitor customer experience. This study concluded that it is possible to fulfill the increasing level of demand and at the same time improve customer satisfaction by implementing changes at the operations level.

Res Publica: Citizenship and Political Representation in Portugal, 1820-1926

The term res publica (literally “thing of the people”) was coined by the Romans to translate the Greek word politeia, which, as we know, referred to a political community organised in accordance with certain principles, amongst which the notion of the “good life” (as against exclusively private interests) was paramount. This ideal also came to be known as political virtue. To achieve it, it was necessary to combine the best of each “constitutional” type and avoid their worst aspects (tyranny, oligarchy and ochlocracy). Hence, the term acquired from the Greeks a sense of being a “mixed” and “balanced” system. Anyone that was entitled to citizenship could participate in the governance of the “public thing”. This implied the institutionalization of open debate and confrontation between interested parties as a way of achieving the consensus necessary to ensure that man the political animal, who fought with words and reason, prevailed over his “natural” counterpart. These premises lie at the heart of the project which is now being presented under the title of Res Publica: Citizenship and Political Representation in Portugal, 1820-1926. The fact that it is integrated into the centenary commemorations of the establishment of the Republic in Portugal is significant, as it was the idea of revolution – with its promise of rupture and change – that inspired it. However, it has also sought to explore events that could be considered the precursor of democratization in the history of Portugal, namely the vintista, setembrista and patuleia revolutions. It is true that the republican regime was opposed to the monarchic. However, although the thesis that monarchy would inevitably lead to tyranny had held sway for centuries, it had also been long believed that the monarchic system could be as “politically virtuous” as a republic (in the strict sense of the word) provided that power was not concentrated in the hands of a single individual. Moreover, various historical experiments had shown that republics could also degenerate into Caesarism and different kinds of despotism. Thus, when absolutism began to be overturned in continental Europe in the name of the natural rights of man and the new social pact theories, initiating the difficult process of (written) constitutionalization, the monarchic principle began to be qualified as a “monarchy hedged by republican institutions”, a situation in which not even the king was exempt from isonomy. This context justifies the time frame chosen here, as it captures the various changes and continuities that run through it. Having rejected the imperative mandate and the reinstatement of the model of corporative representation (which did not mean that, in new contexts, this might not be revived, or that the second chamber established by the Constitutional Charter of 1826 might not be given another lease of life), a new power base was convened: national sovereignty, a precept that would be shared by the monarchic constitutions of 1822 and 1838, and by the republican one of 1911. This followed the French example (manifested in the monarchic constitution of 1791 and in the Spanish constitution of 1812), as not even republicans entertained a tradition of republicanism based upon popular sovereignty. This enables us to better understand the rejection of direct democracy and universal suffrage, and also the long incapacitation (concerning voting and standing for office) of the vast body of “passive” citizens, justified by “enlightened”, property- and gender-based criteria. Although the republicans had promised in the propaganda phase to alter this situation, they ultimately failed to do so. Indeed, throughout the whole period under analysis, the realisation of the potential of national sovereignty was mediated above all by the individual citizen through his choice of representatives. However, this representation was indirect and took place at national level, in the hope that action would be motivated not by particular local interests but by the common good, as dictated by reason. This was considered the only way for the law to be virtuous, a requirement that was also manifested in the separation and balance of powers. As sovereignty was postulated as single and indivisible, so would be the nation that gave it soul and the State that embodied it. Although these characteristics were common to foreign paradigms of reference, in Portugal, the constitutionalization process also sought to nationalise the idea of Empire. Indeed, this had been the overriding purpose of the 1822 Constitution, and it persisted, even after the loss of Brazil, until decolonization. Then, the dream of a single nation stretching from the Minho to Timor finally came to an end.

Comparação entre sistemas de saúde oral de 8 países da união europeia e intervenções por estes desenvolvidas no seguimento das linhas de atuação definidas pela Organização Mundial de Saúde para o ano 2020

RESUMO - Hoje, facilmente se poderá constatar que as doenças orais possuem uma expressiva influência perante a saúde geral, não apenas pela presença da condição por si só, mas também a nível pessoal, social e económico. O seu reflexo traduz-se em parte, no absentismo escolar e laboral, diminuição considerável de produtividade e eficiência, falta de atenção e objetividade. Pelo que é então considerado, um grave problema de saúde pública, afetando de forma mais expressiva, grupos socioeconomicamente desfavorecidos. O acompanhamento e análise do desenvolvimento de iniciativas internacionais, no que ao seguimento das recomendações da Organização Mundial de Saúde diz respeito, poderá ser um ótimo beneficio e impulso para a identificação e aplicação de novos planos de ação. O presente projeto, pretendeu contribuir para a identificação de duas propostas de intervenção em saúde oral ajustadas ao alcance das recomendações da OMS que simultaneamente possam sejam proveitosas para a resolução dos problemas de saúde oral nacionais. Foi realizado um estudo observacional, descritivo e retrospetivo onde foram recolhidos dados acerca de 8 Sistemas de Saúde Oral europeus, previamente selecionados segundo critérios específicos, e iniciativas de saúde oral por eles desenvolvidas. Por fim, foram eleitas duas iniciativas de interesse, possíveis de aplicação futura. Os resultados do estudo apontam para a existência de diferentes iniciativas, enquadradas com as recomendações da OMS. De entre as mesmas, destaca-se uma implementada em 2009, na Suécia, que estando essencialmente assente num acessível subsidio anual fixo pago por cada indivíduo adulto, procura fundamentalmente preservar os esforços de prevenção aplicados nas últimas décadas.

Information provision improvement with a geofencing event-bases system

Nowadays there is a big percentage of the population, specially young users, which are smartphone users and there is a lot of information to be provided within the applications, information provision should be done carefully and should be accurate, otherwise an overload of information will be produced, and the user will discard the app which is providing the information. Mobile devices are becoming smarter and provide many ways to filter information. However, there are alternatives to improve information provision from the side of the application. Some examples are, taking into account the local time, considering the battery level before doing an action and checking the user location to send personalized information attached to that location. SmartCampus and SmartCities are becoming a reality and they have more and more data integrated every day. With all this amount of data it is crucial to decide when and where is the user going to receive a notification with new information. Geofencing is a technique which allows applications to deliver information in a more useful way, in the right time and in the right place. It consists of geofences, physical regions delimited by boundaries, and devices that are eligible to receive the information assigned to the geofence. When devices cross one of these geofences an alert is pushed to the mobile device with the information.

Rigid pavements distresses - pavement condition index evaluation

Pavements require maintenance in order to provide good service levels during their life period. Because of the significant costs of this operation and the importance of a proper planning, a pavement evaluation methodology, named Pavement Condition Index (PCI), was created by the U.S. Army Corps of Engineers. This methodology allows for the evaluation of the pavement condition along the life period, generally yearly, with minimum costs and, in this way, it is possible to plan the maintenance action and to adopt adequate measures, minimising the rehabilitation costs. The PCI methodology provides an evaluation based on visual inspection, namely on the distresses observed on the pavement. This condition index of the pavement is classified from 0 to 100, where 0 it is the worst possible condition and 100 the best possible condition. This methodology of pavement assessment represents a significant tool for management methods such as airport pavement management system (APMS) and life-cycle costs analysis (LCCA). Nevertheless, it has some limitations which can jeopardize the correct evaluation of the pavement behavior. Therefore the objective of this dissertation is to help reducing its limitations and make it easier and faster to use. Thus, an automated process of PCI calculation was developed, avoiding the abaci consultation, and consequently, minimizing the human error. To facilitate also the visual inspection a Tablet application was developed to replace the common inspection data sheet and thus making the survey easier to be undertaken. Following, an airport pavement condition was study accordingly with the methodology described at Standard Test Method for Airport Pavement Condition Index Surveys D5340, 2011 where its original condition level is compared with the condition level after iterate possible erroneous considered distresses as well as possible rehabilitations. Afterwards, the results obtained were analyzed and the main conclusions presented together with some future developments.

On an organizational level: How can the emergency department at Rouge Valley Centenary hospital improve their wait times?

The prolonged wait times may arguably put into question the Canadian Health Act of 1984. Statistics show throughput wait times are 5.5 hours and output wait times for admitted patients are 32.4 hours. After probing and analyzing best practices through a qualitative/quantitative Value Stream Mapping and a qualitative SWOT Analysis; Team Triage and an Overcapacity Protocol is suggested to improve non-admitted patients wait times by 1.89 hours and admitted patients wait times by 16 hours by eliminating wasteful steps in the patient process and upon overcapacity, effectively sharing already stabilized and admitted patients with all wards in the hospital.

Strengthening to seismic action of reinforced columns with rectangular cross-section

The first part of this research work regards the assessment of the mathematical modelling of reinforced concrete columns confined with carbon fibre (CFRP) sheets under axial loading. The purpose was to evaluate existing analytical models, contribute to possible improvements and choose the best model(s) to be part of a new model for the prediction of the behaviour of confined columns under bending and compression. For circular columns, a wide group of authors have proposed several models specific for FRP-confined concrete. The analysis of some of the existing models was carried out by comparing these with several tested columns. Although several models predict fairly the peak load only few can properly estimate the load-strain and dilation behaviour of the columns. Square columns confined with CFRP show a more complex interpretation of their behaviour. Accordingly, the analysis of two experimental programs was carried out to propose new modelling equations for the whole behaviour of columns. The modelling results show that the analytical curves are in general agreement with the presented experimental curves for a wide range of dimensions. An analysis similar to the one done for circular columns was this turn carried out for square columns. Few models can fairly estimate the whole behaviour of the columns and with less accuracy at all levels when compared with circular columns. The second part of this study includes seven experimental tests carried out on reinforced concrete rectangular columns with rounded corners, different damage condition and with confinement and longitudinal strengthening systems. It was concluded that the use of CFRP confinement is viable and of effective performance enhancement alone and combined with other techniques, maintaining a good ductile behaviour for established threshold displacements. As regards the use of external longitudinal strengthening combined with CFRP confinement, this system is effective for the performance enhancement and viable in terms of execution. The load capacity was increased significantly, preserving also in this case a good ductile behaviour for threshold displacements. As to the numerical nonlinear modelling of the tested columns, the results show a variation of the peak load of 1% to 10% compared with tests results. The good results are partly due to the inclusion of the concrete constitutive model by Mander et al. modified by Faustino, Chastre & Paula taking into account the confinement effect. Despite the reasonable approximation to tests results, the modelling results showed higher unloading, which leads to an overestimate dissipated energy and residualdisplacement.
