Fatores individuais de risco de infeção hospitalar : conhecer para prevenir

RESUMO - Medidas efetivas de prevenção e controlo de infeção, assim como a sua aplicação diária e consistente, devem fazer parte da cultura de segurança dos profissionais de saúde para promover a excelência da prestação de cuidados. Também a identificação dos fatores de riscos individuais de infeção é crucial e indispensável para a adoção de medidas para a gestão desses mesmos riscos. A avaliação do risco pretende determinar a probabilidade que um doente tem de adquirir ou disseminar uma infeção hospitalar (IH) (WIRRAL, 2008) nas unidades de saúde. A avaliação deve ser efetuada na admissão do doente e, de forma periódica durante o internamento, usando uma grelha de avaliação, integrada no processo global de cuidados do doente. Efetuada a avaliação de risco individual, que pressupõe a identificação dos fatores de risco do doente (fatores de risco intrínsecos e extrínsecos) pode ser implementado um plano de cuidados individualizado para os gerir. Pretendeu-se com este estudo identificar os fatores de risco de infeção hospitalar do doente que estão presentes na admissão e/ou que podem surgir durante o seu internamento, para que posteriormente seja possível determinar as medidas de prevenção (gestão do risco) a aplicar individualmente. Foi realizado um estudo de caso-controlo com os doentes internados no Hospital dos Lusíadas em 2011 com o objetivo de, por um lado, determinar os fatores de risco individuais que contribuem para a aquisição da IH e, por outro, caraterizar os fatores de risco para uma futura identificação de possíveis medidas de prevenção e controlo da aquisição e transmissão cruzada da infeção hospitalar. A população em estudo foi constituída pelos doentes que foram internados, entre 1 de Janeiro e 31 de Dezembro de 2011 sendo os casos os doentes em que foi identificada a presença de infeção hospitalar através do programa institucional de vigilância epidemiológica das infeções, tendo os controlos sido selecionados numa razão de 3:1 caso. Foi utilizado um suporte estruturado para a colheita de dados, com a listagem de fatores de risco identificados na revisão bibliográfica e de todos os fatores de risco apresentados pelos doentes em estudo. Os fatores de risco identificados que apresentaram um maior significado estatístico foram: a idade acima dos 50 anos, o género masculino, a administração de antimicrobianos nas três semanas anteriores ao internamento, a colocação de cateter venoso central, a algaliação e, no caso dos doentes cirúrgicos, a cirurgia de urgência e a classificação ASA 3. Após a identificação dos fatores de risco da população estudada neste hospital, é agora possível utilizar a informação obtida e delinear investigações adicionais, objetivando a construção de instrumentos para a identificação de doentes com risco aumentado de infeção.

Ruling the Empire: The Portuguese Colonial Office (1820s-1926)

Portugal was one of the first and most enduring European colonial powers of modern times: 1415 and 1975 mark the beginning and the end of a long empire cycle that left impressive imprints in many places. Since it started, the overseas expansion and the exploration of the colonial resources were closely articulated with state-building and the preservation of national independence. A forerunner at the Great Age of Discoveries, but a latecomer in the era of industrialization, in the 19th and early-20th centuries Portugal was a peripheral country, and the economic gap with the rich and industrialized core of Europe was wide. During this period, however, the country faced the critical challenge of ruling vast and geographically scattered overseas territories, and of preserving them from the greed of strong imperialist powers. This article starts by outlining the major developments in the Portuguese colonial policy over a century, since the 1820s until 1926. The independence of Brazil (1822) was a crucial turning point, which brought about a shift towards Africa. The First Republic (1910-1926), pervaded by a nationalist ideology, gave a new impetus to the efforts towards a more effective colonisation. Symptomatically, a Ministry of Colonies was then established for the first time. Second, it describes and analyses the transformation of the central office for colonial affairs – from a small ministerial department to an autonomous ministry -, stressing the increasing bureaucratic specialisation, the growth of the apparatus and its staff, and the introduction of new criteria for the selection and promotion of permanent officials (namely a higher profile given to careers in local colonial administration). Finally, it presents a collective biography of both the politicians (Cabinet ministers) and the administrators (directors-general) who ran the Colonial Office for a large period of the Constitutional Monarchy (from 1851 to 1910) and during the First Republic, thus enabling to assess the impact of regime change on elite circulation and career patterns.

Semantic enrichment of knowledge sources supported by domain ontologies

This thesis introduces a novel conceptual framework to support the creation of knowledge representations based on enriched Semantic Vectors, using the classical vector space model approach extended with ontological support. One of the primary research challenges addressed here relates to the process of formalization and representation of document contents, where most existing approaches are limited and only take into account the explicit, word-based information in the document. This research explores how traditional knowledge representations can be enriched through incorporation of implicit information derived from the complex relationships (semantic associations) modelled by domain ontologies with the addition of information presented in documents. The relevant achievements pursued by this thesis are the following: (i) conceptualization of a model that enables the semantic enrichment of knowledge sources supported by domain experts; (ii) development of a method for extending the traditional vector space, using domain ontologies; (iii) development of a method to support ontology learning, based on the discovery of new ontological relations expressed in non-structured information sources; (iv) development of a process to evaluate the semantic enrichment; (v) implementation of a proof-of-concept, named SENSE (Semantic Enrichment kNowledge SourcEs), which enables to validate the ideas established under the scope of this thesis; (vi) publication of several scientific articles and the support to 4 master dissertations carried out by the department of Electrical and Computer Engineering from FCT/UNL. It is worth mentioning that the work developed under the semantic referential covered by this thesis has reused relevant achievements within the scope of research European projects, in order to address approaches which are considered scientifically sound and coherent and avoid “reinventing the wheel”.

A GNR e a cooperação entre órgãos da polícia criminal na sociedade do risco. Estudo de caso:

Cooperation between police forces is a topic that is increasingly relevant. The emergence of new threats, as well as looking for new ways to fight crime, require from the, careful monitoring and strict sharing of all relevant information. This Work is entitled “The GNR and cooperation between Criminal Police Bodies in the Risk Society. Case Study: District of Lisbon” and aims to study the cooperation and coordination between police forces in Lisbon district, and verify if there is an parallel between the rule of law and the police procedures. The work is organized in four chapters. The first consists in a theoretical framework to perceive the context and objectives of this work. The second addresses the role of the, the different types of cooperation and instruments that promote cooperation between them. The third presents and analyzes the results. Finally, the fourth and last chapter the conclusions are woven answered the questions derived and starting question, tested hypotheses, and those limitations and future recommendations. In conclusion, the District of Lisbon, there is cooperation, materialized in a constant exchange of information, based on personal and informal relationship between the elements of the various Police Forces.
