Fatores explicativos dos resultados obtidos na medida de independência funcional aplicada a doentes com lesão neurológica

RESUMO - A medicina baseada na evidência e as iniciativas para melhorar a qualidade dos cuidados de saúde, têm aumentado bem como o reconhecimento da necessidade de medir os resultados funcionais em todos os cuidados de saúde. A reabilitação tem dado grande importância à necessidade de existência de instrumentos clínicos sensíveis aos resultados funcionais e, tem procurado instrumentos que possam ser usados em ambientes clínicos. A doença cérebro-vascular não é uma entidade patológica ou clínica única, podendo apresentar-se segundo quadros clínicos distintos. É uma ameaça à qualidade de vida não só pela sua elevada incidência e mortalidade, mas também pela alta morbilidade. Considerando estas premissas, pretendeu-se estudar a influência das características individuais, demográficas e de prognóstico neurológico dos doentes em reabilitação nas avaliações de funcionalidade. Utilizou-se a base de dados do Centro de Medicina de Reabilitação de Alcoitão, com todos os episódios de internamento de adultos (2647) que ocorreram entre 2006 e 2011, avaliados com a Medida de Independência Funcional (MIF). Este estudo revela que as variáveis com maior impacto na MIF, quer ao nível do score motor quer no score cognitivo são: a idade, o tempo de evolução e o tempo de internamento. A MIF não apresenta grandes variações entre grupos de diagnóstico no score motor mas releva valores estatisticamente significativos, no que diz respeito a esta variável, ao nível do score cognitivo. Os resultados deste estudo suportam ainda a validade da escala de avaliação e sugerem que esta fornece informações fundamentais para um bom programa de reabilitação.

Undrestanding postoperative cognitive dysfunction: novel insights

ABSTRACT: Background: Sleep is integral to biological function and sleep disruption can result in both physiological and psychological dysfunction. The acute cognitive consequences of sleep loss has been an active field of recent investigation, evidence suggests that sleep disruption in critically ill older adults can result in acute decrements in cognitive functioning. Surgery activates the innate immune system, inducing neuroinflammatory changes that interfere with cognition. The fact that patients with sleep disorders have an increased likelihood of exhibiting postoperative delirium encourages us to investigate the contribution of perioperative SF to the neuroinflammatory and cognitive responses of surgery. Methods: The effects of 24h sleep fragmentation (SF) and surgery were explored on adult C57BL/6J male mice. SF procedure started at 7 am with the home-cages being placed on a large platform orbital shaker cycled every 120 seconds (30 sec on/90 sec off). This procedure lasted for 24h. Stabilized tibia fracture was performed either before or after the 24h SF procedure. Separate cohorts of mice were tested for systemic and hippocampal inflammation and cognition. Results: Twenty-four hours of SF induced non-hippocampal memory dysfunction and increase in systemic IL-6. SF and surgery caused hippocampal-dependent memory impairment, although memory impairment was not exacerbated by combining SF with surgery. One day after either SF or surgery there was a significant increase in IL6 mRNA and TNF-alpha mRNA. These increments were more pronounced when either pre or post operative SF was combined with surgery. Conclusions: We show that while SF and surgery can independently produce significant memory impairment, perioperative SF significantly increased hippocampal inflammation without further cognitive impairment. The dissociation between neuroinflammation and cognitive decline may relate to our use of a sole memory paradigm that does not capture other aspects of cognition, especially learning.

Rehabilitation and reintegration needs of female inmates and promotion mental health in Georgian prison

RESUMO: As mulheres presas encontram-se num sistema essencialmente dirigido por e concebido para homens. As mulheres que entram na prisão geralmente vêm de ambientes marginalizados e desfavorecidos e muitas vezes têm histórias de violência e abuso físico e sexual. As mulheres presas são um grupo particularmente vulnerável, uma vez que dentro do sistema prisional as suas necessidades de saúde e higiene são muitas vezes negligenciadas. O primeiro passo para o desenvolvimento de programas e práticas sensíveis ao género é compreender as características das mulheres delinquentes e definir fatores de vida específicos que contribuem para a formação do comportamento criminoso de mulheres. Em junho de 2012 foi realizada uma investigação na única prisão feminina da Geórgia, para estudar as necessidades mentais e psicossociais das mulheres presas. O objetivo da pesquisa foi o desenvolvimento de programas de apoio pertinentes para a reabilitação, ressocialização e reintegração, e a elaboração de recomendações práticas para a gestão das prisões. Foi desenvolvido um instrumento de pesquisa (inquérito) com uma fundamentação conceptual baseada em quatro principais teorias: Teoria dos Caminhos (Pathways Theory), teoria do desenvolvimento psicológico da mulher (Theory of Women’s Psychological Development), Trauma e Teorias da Dependência (Trauma and Addiction Theories). Foram inquiridas 120 mulheres presas. Os resultados deste estudo mostram que muitas das necessidades das mulheres presas são diferentes das dos homens e requerem estratégias adaptadas às suas características e situações psicossociais específicas. A maioria das mulheres encarceradas é jovem, enérgica, pode trabalhar, tem profissão e família. As presas sofrem de problemas psicológicos e muitas vezes são rejeitadas pelas suas famílias. Uma parte substancial das mulheres presas tem múltiplos problemas de saúde física e mental. A maioria delas tem filhos e sofre com o facto das crianças estarem a crescer longe da mãe. Com base nos resultados desta investigação é possível elaborar um contexto promotor do planeamento e desenvolvimento de serviços com um enfoque de género na prisão. Na perspetiva de longo prazo, o conhecimento das necessidades básicas e a introdução de programas e serviços com necessidades específicas pertinentes irá beneficiar as presas e as suas famílias, e melhorar a eficácia do sistema de justiça criminal.----------ABSTRACT: Female inmates find themselves in a system essentially run by men for men. Women who enter prison usually come from marginalized and disadvantaged backgrounds and are often characterized by histories of violence, physical and sexual abuse. Female prisoners constitute an especially vulnerable group given their specific health and hygienic needs within the system are often neglected. The first step in developing gender-sensitive program and practice is to understand female offenders’ characteristics and the specific life factors that shape women’s patterns of offending. In June 2012 a research was carried out in the Georgian only female prison facility to assess the mental and psychosocial needs of women prisoners, aiming to develop effective support programs for their rehabilitation, re-socialization and reintegration, as well as to elaborate new recommendations concerning prison management. A survey instrument (questionnaire) was developed within a theoretical framework based on four fundamental theories: Pathways Theory, Theory of Women’s Psychological Development and Trauma and Addiction Theories. Sample size was defined to be 120 surveyed persons. The study showed that needs of incarcerated women were different from those of men, thus requiring approaches tailored to their specific psychosocial characteristics and situations. The basic population of imprisoned women consisted of young, energetic, working-age females, most often with a professional qualification. Female prisoners suffered from psychological problems and are were more likely to be rejected by their families. Most of them had children and suffered that the children were growing without mothers. A substantial proportion of women offenders had multiple physical and mental health problems. Based on the study findings a conceptual framework can be elaborated towards planning and developing gender-sensitive services in prison. In the long-term perspective, acknowledgement of baseline needs and introduction of the relevant needs-specific programs and services may benefit women prisoners as well as their families, improving the effectiveness of the criminal justice system.

Rehabilitation of renders of old buildings in Portugal: survey, supporting methodology proposal and case study

The main purpose of the research is to present a proposal for a methodology to support the rehabilitation project of renders of old buildings in Portugal. To achieve the objective it was considered essential to define the main types of participants and aspects to integrate the proposal. The research methodology consists in an inquiry presented to professional participants in rehabilitation, a market study of materials and products available in Portugal, the design of a methodology proposal and its application to a case study. The inquiry sample totals 24 answers from the targeted professionals. A sequence of relevant supporting procedures consists in the proposal, which aims to provide a supporting methodology to decide and project in this context and also to be tested with its application to the building. This proposal was applied to an old building with load-bearing stone masonry walls and air-lime based renders. It was concluded that the assessment of the building and external renderings’ condition, its diagnosis and of the supporting walls, the definition of intervention, the specification of materials to be used and performance requirements to comply, and also plans for conservation and periodic maintenance, are crucial. From the inquiry, compatibility between materials and complementary roles and points of view of different types of participants in rehabilitation must be highlighted. A proposal for a methodology to support the project could provide useful guidance particularly for architects and construction engineers, and improve the understanding of direct participants on site, therefore contributing for the correct implementation of intervention.

The main purpose of the research is to present a proposal for a methodology to support the rehabilitation project of renders of old buildings. To achieve the objective it was considered essential to define the main types of participants and aspects to integrate the proposal. The research methodology consists in an inquiry presented to several professional participants in rehabilitation, a market study of materials and products available in Portugal, the design of a methodology proposal and its application to a case study. The inquiry sample totals 24 answers from the targeted professionals.
