Efeitos do tratamento com Hidrogel na cicatrização de úlceras venosas de membros inferiores: revisão sistemática

Chronic venous disease (CVD) is evident among the chronic diseases and affects the elderly population and primarily is responsible for leg ulcers in this population. The use of dressings in the care of a venous ulcer is a fundamental part of the treatment for healing, however, evidence to assist in choosing the best dressing is scarce. The main objective of this study was to evaluate the effectiveness of treatment with hydrogel in the healing of venous ulcers using search methods, synthesis of information and statistical research through a systematic review and meta-analysis. Randomized controlled trials were selected in the following databases: CENTRAL; DARE; NHS EED; MEDLINE; EMBASE; CINAHL. Beyond these databases three websites were consulted to identify ongoing studies: ClinicalTrials.gov, OMS ICTRP e ISRCTN. The primary outcomes were analyzed: complete wound healing, incidence of wound infection and the secondary were: changes in ulcer size, time to ulcer healing, recurrence of ulcer, quality of life of participants, pain and costs of treatment. Four studies are currently included in the review with a total of 250 participants. The use of hydrogel appears to be superior to conventional dressing, gauze soaked in saline, for the healing of venous leg ulcers; 16/30 patients showed complete healing of ulcers (RR 5,33, 95%CI [1,73,16,42]). The alginate gel was shown to be more effective when compared to the hydrogel dressing in reduction of the wound area; 61,2% (± 26,2%) with alginate e 19,4% (± 24,3%) with hydrogel at the end of four weeks of treatment. Manuka honey has shown to be similar to the hydrogel dressings in percentage of area reduction. This review demonstrated that there is no evidence available about the effectiveness of the hydrogel compared to other types of dressings on the healing of venous leg ulcers of the lower limbs, thus demonstrating the need of future studies to assist health professionals in choosing the correct dressing.

O Processo de revisão do benefício de prestação continuada-BPC: uma lógica de exclusão ou inclusão social

This research comprises a study about the social assessment performed by the Social Worker in the review process of the Benefit of Continued Installment. The Benefit of Continued Installment was implemented in 1996 and guarantees a minimum salary to the deficiency person and to an elder with sixty five years or more and that proves not to have ways to support neither himself/herself nor his/her own family. It is a demand to include in the BPC that the maximum income of a family does not exceed ¼ of minimum salary and that every two years this benefit to be revised to evaluate its continuity based in its original conditions. This study was carried out in the municipality of Natal/RN, with thirteen social workers, being the collection of data performed through interviews and social assessments of the users that count with the benefit. The results show that the users selected by the criterion of the income, present a profile of poverty and deprivations demonstrated through several situations survived in its daily life, indicative of vulnerability. It was demonstrated that the Social workers has relative autonomy in the evaluations along with the users and that it denotes the necessity of inclusion. However, by following the imposed criteria, it corroborates with the logic of exclusion. So, it is identified in the Municipality of Natal/RN, following the orientation given the politics of social work at national level, the implementation of revision of the BPC, for the social workers, from rigorous processes of selection and exclusions

Garantia literária: elementos para uma revisão crítica após um século

This study contributes to a critical synthesis of the principle of literary warrant, initially formulated by Hulme in 1911. Hulme proposed that the terms of a classification system should be derived from the literature to be classified, rather than based on purely theoretical considerations. Founding literary warrant on literature which is actually documented rather than on scientific or philosophical classifications or on the supposed authority of the first classificationists implied a clear departure from the conceptions of Harris and Dewey, who had used the classifications of Bacon and Leibniz as models. The validity of this principle over the past century is studied by means of diverse documental data (entries in dictionaries, retrieval by Google, etc.), as it is recognized as a main methodological element for classification standards and systems. This study also discusses the situation with respect to the top-down or bottom-up methodologies of system design. Three traditional applications of literary warrant are described as well as three new applications are suggested, in light of its methodological potential. It is possible to conclude that this principle will find increasing applications in other contexts, within and beyond Information Science.

Revisão por pares na Revista Brasileira de Educação Especial

O artigo discute algumas questões relativas ao procedimento de revisão por pares na avaliação de originais submetidos a um periódico. Essa avaliação é aceita como necessária para assegurar a qualidade científica de artigos publicados, já que a integridade da literatura especializada é considerada essencial para o desenvolvimento da ciência. Entretanto, há críticas à revisão por pares, incluindo o longo tempo decorrido entre a entrega dos originais e a publicação, o tempo e a energia despendidos pelos autores e revisores, a subjetividade na avaliação e outros problemas que podem introduzir vieses na área. A Revista Brasileira de Educação Especial, que adota a avaliação cega por pares, tem-se mostrado relativamente versátil. O tempo médio entre o recebimento dos originais e o aceite final, depois de passar pela revisão por pares e conseqüente ajuste por parte dos autores, é de cerca de cinco meses e meio. Na literatura especializada, encontram-se sugestões como a eliminação de avaliação e publicação de todos os textos submetidos, em meios eletrônicos, menos onerosos e mais versáteis, deixando que os próprios leitores façam a sua avaliação. A análise procedida conclui que a revisão por pares é necessária. Aponta a necessidade de se realizarem discussões sobre a própria avaliação, para que se desenvolvam procedimentos mais eficientes de controle de qualidade das publicações. Sugere que a avaliação efetiva é feita pela própria comunidade acadêmica, após a publicação, mediante reconhecimento coletivo do valor científico da publicação, na forma de impacto que pode causar sobre novas investigações e construção do conhecimento na área.
