A efectividade de um programa de exercícios terapêuticos na doença osteo-articular no idoso

RESUMO: O presente estudo teve como objectivo avaliar a efectividade de um programa de intervenção de fisioterapia comparativamente ao tratamento conservador (calor húmido, ultra-som e massagem), relativamente à dor e capacidade funcional, no utente idoso com doença osteoarticular do joelho. A amostra foi aleatória, tendo sido seleccionados 20 utentes que respeitaram os critérios de inclusão, e que foram distribuídos aleatoriamente pelos dois grupos de tratamento, 9 no grupo A (experimental) e 11 no grupo B (controle). Todos os utentes deram o seu consentimento informado. Trata-se de um estudo experimental, controlado aleatorizado (RCT). A intervenção em estudo consistiu em 15 sessões de tratamento individuais, efectuadas 3 vezes por semana. O programa terapêutico efectuado pelo grupo A incluiu o tratamento conservador (20 minutos calor húmido, 5 minutos ultra-som (contínuo; 1,5W/cm2) e aproximadamente 10 minutos de massagem local) e o protocolo de exercícios terapêuticos em estudo. Este protocolo de exercícios foi progredindo semanalmente em termos da sua intensidade. Os utentes do Grupo B efectuaram apenas o tratamento conservador (tal como no grupo A). Para avaliar a dor e a capacidade funcional foi utilizado o Questionário knee Injury and Osteoarthritis Outcome Score. A análise dos resultados foi realizada através dos testes Mann-Whitney e Kruskal-Wallis para a comparação entre grupos. Os resultados sugerem não haver diferenças estatisticamente significativos entre os grupos, embora o grupo de controle tenha obtido melhores resultados. O grupo B apresentou uma diminuição da dor de 17,33, comparativamente aos valores de -3,00 no grupo A (p=0,101), e melhoria da capacidade funcional de 13,00, mantendo-se a capacidade funcional igual, no grupo A (0,00) p=0,080). Estes resultados parecem sugerir que não há diferenças significativas entre as duas modalidades de intervenção, realçando a necessidade de continuar a investigar este protocolo de exercícios e a sua efectividade.-----------------ABSTRACT: The aims of this study was to evaluate the effectiveness of a treatment program compared with conventional treatment (post hoots, ultrasound and massage), for the outcomes pain and functional ability in elderly with knee osteoarthritis. The sample was non-probability, and 20 patients have been selected that fulfilled the criteria for inclusion and who were randomly assigned to the two treatment groups, in group A and 11 in group B. All of the patients gave their informed consent. This is an experimental, randomized controlled trial (RCT) with blinded assessment, of comparative design. This study protocol program was carry out in 15 individual treatment sessions, 3x per week. The therapeutic program made by group A consisted of the performance of conservative treatment: 20 minutes of hot packs, 5 minutes of ultrasound (continuous, 1.5 W/cm2) and 10 minutes of massage plus the exercise protocol therapy consisted of: isometric exercises of quadriceps contractions, muscle strengthening for knee and aerobic training. This exercise protocol was progressing every week in terms of its intensity. The users in Group B, only made the conservative treatment (such as in group A). In this study there were evaluated the pain and functional capacity, assessed by questionnaire knee Injury Osteoarthritis Outcome Score. For comparison between groups were used Mann-Whitney and Kruskal-Wallis tests. The results revealed that in group B was that it obtained better results, although they are not statistical significance. The group B show a decrease in pain of 17.33 compared to -3.00 in group A (p = 0.101), and improved capacity functional of 13.00, keeping in group A (0.00) (p = 0.080). However, the differences are not statistically significant. These results show that there are not statistically significant in both treatments, but more studies are needed.

Evidence of spotted fever group rickettsiae in state of Rio de Janeiro, Brazil

Ticks were obtained from dogs from February to September of 1999 at weekly intervals, in the County of Piraí, State of Rio de Janeiro. Four hundred seventy four ixodids were taxonomically identified, 103 Amblyomma cajennense, seven Amblyomma ovale, 209 Rhipicephalus sanguineus, and 155 Amblyomma sp. An hemolymph test associated with Giemsa's stain revealed two specimens in 163 ticks tested (R. sanguineus and Amblyomma sp), containing rickettsia-like organisms. Direct immunofluorescence verified the presence of spotted fever group rickettsia in one specimen of R. sanguineus. Considering the limited information on rickettsiosis in Brazil, principally in relation to the vectors involved in perpetuating it in foci, these preliminary results give us an idea on the importance of infection in ticks, allowing to expand our knowledge on this zoonosis.

A utilidade da demonstração de fluxos de caixa na ótica dos Técnicos Oficiais de contas

O tema Fluxos de Caixa tem cada vez mais importância nas empresas e no relato financeiro das mesmas. Com a entrada em vigor do Sistema de Normalização Contabilística em 2010, tornou-se obrigatória a apresentação da Demonstração de Fluxos de Caixa nas Demonstrações Financeiras das empresas que adotem o regime geral. Segundo a Norma Contabilística e de Relato Financeiro 2 – Demonstração de Fluxos de Caixa, nos seus parágrafos 7 e 8, a Demonstração de Fluxos de Caixa “deve relatar os fluxos de caixa durante o período classificados por atividades operacionais, de investimento e de financiamento. A classificação por atividades proporciona informação que permite aos utentes determinar o impacto dessas atividades na posição financeira da entidade e nas quantias de caixa e seus equivalentes”. Possibilita a avaliação das empresas, a deteção de sinais de fragilidade e ajuda a decidir qual o melhor caminho a seguir. O objetivo central deste trabalho consiste em evidenciar a importância e utilidade da Demonstração de Fluxos de Caixa para os profissionais de contabilidade e para os utilizadores da informação financeira, na ótica dos Técnicos Oficiais de Contas, e será alcançado através de um questionário a este grupo de profissionais. Os resultados obtidos permitiram-nos aferir que os Técnicos Oficiais de Contas consideram esta Demonstração Financeira importante e atribuem-lhe a utilidade que efetivamente representa, isto é, consideram-na uma peça indispensável para a gestão de tesouraria como para a gestão operacional, financeira ou de investimentos de qualquer empresa. Contudo, na sua opinião, esta Demonstração é ainda pouco valorizada pelos utilizadores da informação financeira.

Do Spirituality and Faith Make a Difference? Report from the Southern European Psycho-Oncology Study Group

OBJECTIVE: In the last decade, some attention has been given to spirituality and faith and their role in cancer patients' coping. Few data are available about spirituality among cancer patients in Southern European countries, which have a big tradition of spirituality, namely, the Catholic religion. As part of a more general investigation (Southern European Psycho-Oncology Study--SEPOS), the aim of this study was to examine the effect of spirituality in molding psychosocial implications in Southern European cancer patients. METHOD: A convenience sample of 323 outpatients with a diagnosis of cancer between 6 to 18 months, a good performance status (Karnofsky Performance Status > 80), and no cognitive deficits or central nervous system (CNS) involvement by disease were approached in university and affiliated cancer centers in Italy, Spain, Portugal, and Switzerland (Italian speaking area). Each patient was evaluated for spirituality (Visual Analog Scale 0-10), psychological morbidity (Hospital Anxiety and Depression Scale--HADS), coping strategies (Mini-Mental Adjustment to Cancer--Mini-MAC) and concerns about illness (Cancer Worries Inventory--CWI). RESULTS. The majority of patients (79.3%) referred to being supported by their spirituality/faith throughout their illness. Significant differences were found between the spirituality and non-spirituality groups (p ≤ 0.01) in terms of education, coping styles, and psychological morbidity. Spirituality was significantly correlated with fighting spirit (r = -0.27), fatalism (r = 0.50), and avoidance (r = 0.23) coping styles and negatively correlated with education (r = -0.25), depression (r = -0.22) and HAD total (r = -0.17). SIGNIFICANCE OF RESULTS: Spirituality is frequent among Southern European cancer patients with lower education and seems to play some protective role towards psychological morbidity, specifically depression. Further studies should examine this trend in Southern European cancer patients.

BIWiki - Using a Business Intelligence Wiki to Form a Virtual Community of Practice for Portuguese Master's Students

Web 2.0 software in general and wikis in particular have been receiving growing attention as they constitute new and powerful tools, capable of supporting information sharing, creation of knowledge and a wide range of collaborative processes and learning activities. This paper introduces briefly some of the new opportunities made possible by Web 2.0 or the social Internet, focusing on those offered by the use of wikis as learning spaces. A wiki allows documents to be created, edited and shared on a group basis; it has a very easy and efficient markup language, using a simple Web browser. One of the most important characteristics of wiki technology is the ease with which pages are created and edited. The facility for wiki content to be edited by its users means that its pages and structure form a dynamic entity, in permanent evolution, where users can insert new ideas, supplement previously existing information and correct errors and typos in a document at any time, up to the agreed final version. This paper explores wikis as a collaborative learning and knowledge-building space and its potential for supporting Virtual Communities of Practice (VCoPs). In the academic years (2007/8 and 2008/9), students of the Business Intelligence module at the Master's programme of studies on Knowledge Management and Business Intelligence at Instituto Superior de Estatistica e Gestao de Informacao of the Universidade Nova de Lisboa, Portugal, have been actively involved in the creation of BIWiki - a wiki for Business Intelligence in the Portuguese language. Based on usage patterns and feedback from students participating in this experience, some conclusions are drawn regarding the potential of this technology to support the emergence of VCoPs; some provisional suggestions will be made regarding the use of wikis to support information sharing, knowledge creation and transfer and collaborative learning in Higher Education.

Hearing impairment in patients with tuberculosis from Northeast Brazil

The aim of this paper is to describe the auditory profile of subjects who were given streptomycin treatment for tuberculosis in the years 2000 and 2001, in Recife, Northeast Brazil. The Injury Notification Database at the Municipal Department of Health was consulted and 78 individuals who had been on streptomycin during the period under study were selected. Forty-two individuals were excluded, of whom five were over 59 years of age and two were under 18 years. Nineteen turned out to be deceased, 13 could not be found, two were serving prison terms and one refused to participate. As a result, only 36 subjects participated in the study. These 36 individuals were interviewed and underwent meatoscopy and audiometry. The mean age of the group under study was 38.8 years old and males predominated (79.4%). Twenty-seven patients (75%) showed hearing impairment, the bilateral sensorineural type (63.9%) being the most frequent, mainly affecting the high frequencies over 4000 Hz. In the light of findings showing a high percentage of hearing impairment complaints among users of streptomycin, this issue seems to warrant an in-depth investigation, as does the implementation of an auditory follow-up routine for patients undergoing such chemotherapy for tuberculosis.

Access and information behaviour of European Documentation Centres users in Portugal and Spain: a comparative study

The aim of this study was to undertake a comparative analysis of the practices and information behaviour of European information users who visit information units specialising in European information in Portugal and Spain. The study used a quantitative methodology based on a questionnaire containing closed questions and one open question. The questions covered the general sociological profile of the respondents and their use of European Document Centres, in addition to analysing aspects associated with information behaviour relating to European themes. The study therefore examined data on the preferred means and sources for accessing European information, types of documents and the subjects investigated most. The use of European databases and the Internet to access material on Europe was also studied, together with the reasons which users considered made it easy or difficult to access European information, and the aspects they valued most in accessing this information. The questionnaire was administered in European Document Centres in 2008 and 2010.

Cell surface hydrophobicity and adherence of a strain of group B streptococci during the post-antibiotic effect of penicillin

The minimum inhibitory concentration and post-antibiotic effects of an antimicrobial agent are parameters to be taken into consideration when determining its dosage schedules. The in vitro post-antibiotic effects on cell surface hydrophobicity and bacterial adherence were examined in one strain of group B streptococci. Exposure of the microorganism for 2 h at 37 °C to 1 x MIC of penicillin induced a PAE of 1.1 h. The cell surface charge of the Streptococcus was altered significantly during the post-antibiotic phase as shown by its ability to bind to xylene: hydrophobicity was decreased. Bacterial adherence to human buccal epithelial cells was also reduced. The results of the present investigation indicate that studies designed to determine therapeutic regimens should evaluate the clinical significance of aspects of bacterial physiology during the post-antibiotic period.

XATA 2010 : XML : Associated Technologies and Applications, 8th

These are the proceedings for the eighth national conference on XML, its Associated Technologies and its Applications (XATA'2010). The paper selection resulted in 33% of papers accepted as full papers, and 33% of papers accepted as short papers. While these two types of papers were distinguish during the conference, and they had different talk duration, they all had the same limit of 12 pages. We are happy that the selected papers focus both aspects of the conference: XML technologies, and XML applications. In the first group we can include the articles on parsing and transformation technologies, like “Processing XML: a rewriting system approach", “Visual Programming of XSLT from examples", “A Refactoring Model for XML Documents", “A Performance based Approach for Processing Large XML Files in Multicore Machines", “XML to paper publishing with manual intervention" and “Parsing XML Documents in Java using Annotations". XML-core related papers are also available, focusing XML tools testing on “Test::XML::Generator: Generating XML for Unit Testing" and “XML Archive for Testing: a benchmark for GuessXQ". XML as the base for application development is also present, being discussed on different areas, like “Web Service for Interactive Products and Orders Configuration", “XML Description for Automata Manipulations", “Integration of repositories in Moodle", “XML, Annotations and Database: a Comparative Study of Metadata Definition Strategies for Frameworks", “CardioML: Integrating Personal Cardiac Information for Ubiquous Diagnosis and Analysis", “A Semantic Representation of Users Emotions when Watching Videos" and “Integrating SVG and SMIL in DAISY DTB production to enhance the contents accessibility in the Open Library for Higher Education". The wide spread of subjects makes us believe that for the time being XML is here to stay what enhances the importance of gathering this community to discuss related science and technology. Small conferences are traversing a bad period. Authors look for impact and numbers and only submit their works to big conferences sponsored by the right institutions. However the group of people behind this conference still believes that spaces like this should be preserved and maintained. This 8th gathering marks the beginning of a new cycle. We know who we are, what is our identity and we will keep working to preserve that. We hope the publication containing the works of this year's edition will catch the same attention and interest of the previous editions and above all that this publication helps in some other's work. Finally, we would like to thank all authors for their work and interest in the conference, and to the scientific committee members for their review work.

Estudo das vias de acesso aos cuidados psiquiátricos na equipa de Sintra

Resumo: O estudo das vias de acesso à consulta de Psiquiatria permite identificar os parceiros mais importantes no acesso dos utentes aos serviços psiquiátricos. O modelo de Goldberg-Huxley considera que o acesso às consultas de Psiquiatria se faz principalmente através dos cuidados de saúde primários. Material e Métodos: Para estudar as vias de acesso aos cuidados psiquiátricos utilizamos a Encounter Form, questionário desenvolvido por Gater. Foi também avaliada a classe social dos utentes utilizando a Escala de Graffar. Este inquérito foi passado na Consulta de Psiquiatria de Sintra a utentes de primeira consulta. A amostra estudada foi de 93 utentes. O objectivo do estudo foi conhecer a trajectória do utente desde que teve necessidade de ser consultado até chegar à consulta de Psiquiatria, os sintomas que determinaram a decisão de procurar ajuda e a influência da classe social no tempo de percurso. Resultados: Observa-se que os utentes passam pela Medicina Geral e Familiar em 71 % dos casos, pela Urgência Psiquiátrica em 16,1 % dos casos, pela Medicina Especializada Hospitalar em 10,7 % dos casos e pela Urgência Geral em 1,1 % dos casos. Na escala de Graffar a classe social prevalente é a média (Classe III). O tempo de percurso foi maior que em estudo similar realizado em 1991. A classe Social III foi a que teve tempo de percurso maior. Conclusões: O estudo conclui que o acesso a esta consulta de Psiquiatria se faz principalmente através da Medicina Geral e Familiar. O tempo de percurso é maior que o desejável por falta de recursos humanos.------- ABSTRACT: Introduction: The study of the Pathways to Psychiatric Care identifies the most important partners in accessing psychiatric services. The Goldberg- Huxley model believes that access to Psychiatric consultation is done preferably through the primary health care. Material and Methods: This survey included 93 first-time users of the Psychiatric Consultation of Sintra. The aim was to study the trajectory of the user since he had felt a need to be consulted until the consultation of Psychiatry, the symptoms that led to the decision to seek help and influence of social class in time spent in pathways. This study used the Encounter Form, a questionnaire developed by Gater. Social class of users was also assessed using the Scale of Graffar. Results: We observed that users have contact with General Practitionaires in 71% of cases, the Psychiatric Urgency in 16.1% of cases, the Hospital Medical Specialist in 10.7% of cases and the General Urgency in 1,1% of cases. On the Graffar scale middle class (Class III) was the most prevalent. The travel time spend in pathways was reater than that obtained in a similar study carried out in 1991. Social Class III group had a greater time spent on pathways. Conclusions: The study concludes that access to this Psychiatric consultation is principally through general practice. The time spent in pathways is greater than desirable due to lack of resources.

Sistema aplicacional para o acompanhamento e monitorização de casos de perturbação psicótica

Pretende-se, na presente dissertação, descrever o trabalho desenvolvido e os conhecimentos adquiridos no decorrer do projeto “iCOPE”, realizado no âmbito do curso de Mestrado em Engenharia de Computação e Instrumentação Médica. O projeto consistiu no desenvolvimento de um sistema aplicacional para o auxílio à prestação de serviços e cuidados de saúde a pacientes com doenças psicóticas tanto através de ferramentas de autogestão, como por funcionalidades que permitirão a um terapeuta monitorizar as ocorrências comunicadas pelos respetivos pacientes atribuídos. As tarefas à responsabilidade do autor desta dissertação compreenderam o levantamento e especificação de requisitos funcionais, o desenvolvimento das funcionalidades e interfaces de gestão de utilizadores e administração do sistema, o desenvolvimento das funcionalidades e interfaces para utilização pelos terapeutas e a criação de ferramentas para a instalação do servidor aplicacional central, existindo ainda cooperação no desenvolvimento de funcionalidades e interfaces para utilização pelos pacientes, nomeadamente ao nível da modelização da base de dados e na realização de testes e deteção de erros. Os resultados da avaliação das interfaces desenvolvidas, obtidos por meio da análise de respostas dadas por um grupo de potenciais utilizadores a um inquérito de usabilidade anónimo, demonstraram que estes estão satisfeitos com a solução implementada, havendo, no entanto, margem para futuros melhoramentos e incremento de funcionalidades.
