O câncer do trato gastrointestinal tem sua importância no perfil de mortalidade do Brasil, estando entre os dez mais incidentes do país. A detecção precoce garante uma melhor qualidade de vida para os doentes oncológicos, porém frequentemente estes chegam aos centros de tratamento em fase avançada da doença. O estudo objetiva investigar as dificuldades de acesso ao diagnóstico e tratamento para os pacientes com câncer gastrointestinal atendidos pelo Sistema Único de Saúde. Com este intuito, realizou-se uma pesquisa observacional descritiva e sob a forma de um questionário foram coletados dados de pacientes em tratamento em dois hospitais públicos de Belém, no período de março a junho de 2013. Preencheram os critérios de inclusão 122 pacientes que foram agrupados em diferentes trajetórias de atendimento. Além disso, foram também obtidas informações registradas nos prontuários desses pacientes. A análise dos dados demonstrou que o diagnóstico da doença em 68,1% foi realizado pelo médico generalista; a maior dificuldade, nessa fase, foi o acesso ao diagnóstico gerando gastos com exames, pois a maioria dos pacientes (68,9%) não realizou exames especializados através do Sistema Único de Saúde, mas com recursos próprios. Nos centros/ unidades de referência em oncologia, as dificuldades relatadas por 56 pacientes começam com a marcação da consulta médica, ocorrendo demora do agendamento pela instituição para 94,6% desses doentes. A falta de leito para internação foi apontada como o maior entrave (54.4%) para iniciar a terapêutica cirúrgica, particularmente para o câncer gástrico e de cólon e reto. A análise das trajetórias percorridas pelos doentes, desde o inicio dos sintomas até o atendimento na unidade de referência, revela que o diagnóstico da doença em 50% dos pacientes ocorreu somente após 10 meses do inicio dos sintomas, e o tratamento iniciou só depois de 90 dias do diagnóstico. O tempo que os pacientes permanecem sintomáticos sem um diagnóstico impacta negativamente no prognóstico. Nesta pesquisa, os casos de câncer gástrico e de cólon e reto foram diagnosticados tardiamente (estádio IV e IIIB) e, por conseguinte o tratamento não ocorreu no prazo desejável.

PURPOSE: To analyze the time between the first symptom and treatment in patients treated for breast cancer in public hospitals in the Federal District. METHODS: This was a cross-sectional analysis. We interviewed 250 women diagnosed with breast cancer treated in six hospitals of the State Department of Health of the Federal District from November 2009 to January 2011. The time intervals studied were the time between the detection of the symptoms and treatment subdivided into intervals until and after the first medical appointment. The variables were: age, menopausal status, color, educational level, average monthly household income, origin, reason for the initial consultation, staging, tumor size, laterality, metastasis to axillary lymph nodes, neoadjuvant chemotherapy, and type of surgery. The Mann-Whtney test was used to assess the association of these variables with the time intervals until treatment. RESULTS: The mean age was 52 years, with a predominance of white women (57.6%), from the Federal District (62.4%), with a family income of up to 2 minimum wages (78%), and up to four years of schooling (52.4%). The staging of the disease ranged from II to IV in 78.8% of the women. The time between the first symptom and treatment was 229 days (median). After detection of the first symptom, 52.9% of the women attended a consultation within 30 days and 88.8% took more than 90 days to start treatment. Women with elementary school education had a greater delay to the start of treatment (p=0.049). CONCLUSIONS: There was a significant delay to start treatment of women with breast cancer in public hospitals of the Federal District, suggesting that efforts should be made to reduce the time needed to schedule medical appointments and to diagnose and treat these patients.

Introduction: In the digital environment, metadata influence both in data access and information retrieval and are used as search elements to facilitate locating resources on the Web. Objective: In this perspective, the aim is to present the methodology BEAM, developed in Biblioteca de Estudos e Aplicação de Metadados, of the Research Group “Novas Tecnologias em Informação” in Universidade Estadual Paulista and used to define the metadata for describing information resources. Methodology: The methodology used for the construction of the research is exploratory and bibliographic and was developed based on the theoretical method Chuttur (2011) and the life cycle of data from the DataOne (2012) and also the PDCA cycle and tool 5W1H . Results: The seven steps of the methodology are presented and also the necessary guidelines for their implementation. Conclusions: We conclude pointing BEAM methodology that can be adopted by libraries in the construction of catalogs aimed at meeting the needs of users.

In the paper analyzes the process of knowledge construction in the news regarding the emergence of massive information and communication technologies. In this context, through a qualitative approach, first we examine the potential of production, dissemination, access and use information in a technocratic perspective, and secondly, the negative impacts stemming from the computed mediation, mainly linked to the complexity of policies of democratization of access to information and loss of criticality of science. The focus of this review focuses on the current model of information search and knowledge construction through the Web, outlining aspects inherent to the process in general. Similarly, envision different contributions of information science for the systematization of human knowledge, guided through the social actions of professionals working in various fields, with emphasis on the information representation and retrieval. It is hoped that work can contribute to the current thematic reflection on the production, dissemination and use of information as well as on digital inclusion policies.

Information retrieval has been much discussed within Information Science lately. The search for quality information compatible with the users needs became the object of constant research.Using the Internet as a source of dissemination of knowledge has suggested new models of information storage, such as digital repositories, which have been used in academic research as the main form of autoarchiving and disseminating information, but with an information structure that suggests better descriptions of resources and hence better retrieval.Thus the objective is to improve the process of information retrieval, presenting a proposal for a structural model in the context of the semantic web, addressing the use of web 2.0 and web 3.0 in digital repositories, enabling semantic retrieval of information through building a data layer called Iterative Representation.The present study is characterized as descriptive and analytical, based on document analysis, divided into two parts: the first, characterized by direct observation of non-participatory tools that implement digital repositories, as well as digital repositories already instantiated, and the second with scanning feature, which suggests an innovative model for repositories, with the use of structures of knowledge representation and user participation in building a vocabulary domain. The model suggested and proposed ─ Iterative Representation ─ will allow to tailor the digital repositories using Folksonomy and also controlled vocabulary of the field in order to generate a data layer iterative, which allows feedback information, and semantic retrieval of information, through the structural model designed for repositories. The suggested model resulted in the formulation of the thesis that through Iterative Representation it is possible to establish a process of semantic retrieval of information in digital repositories.

The Information Technology and Communication (ICT) made possible to adapt bibliographic catalogs to the digital environment, giving them more speed, flexibility and efficiency in the information retrieval. The FRBR, as a conceptual model for the bibliographic universe based on entity-relationship modeling, brought to the Librarianship area the possibility of making more efficient operation catalogs. The FRBR model was the first initiative caring about how to accomplish the conceptual modeling of bibliographic catalogs, to do not spend more efforts in individual developments of distinct and inconsistent modeling.However, even many years after its publication, there were few real implementation initiatives. The aim of this study is to present the model, based on its main features and structure, and bring to the discussion some considerations and inconsistencies that, according to the literature, may be the cause of its failure so far. It s based on the national and international literature about conceptual modeling and about the FRBR model.
