Gravidez na adolescência: determinante para prematuridade e baixo peso

Prematurity and low birth weight are public health problems. This paper aims to relate the occurrence of premature labors and low birth weight with adolescent pregnancy. We performed a literature review about the socioeconomic and cultural conditions of adolescent pregnancy and perinatal results. Through bibliographical data, we identified observational and systematic review articles that deal with the subject. The literature analysis permits us to conclude that adolescent pregnancies as well as the socioeconomic and cultural environment in which the young mother is inserted are associated with the increased frequency of prematures and low birth weight babies. The development and the implementation of effective public policies directed to that population are necessary to a better approach of the problem.

Measures of quality of life in children with cochlear implant: systematic review

The use of cochlear implant (CI) in children enables the development of listening and communication skills, allowing the child's progress in school and to be able to obtain, maintain and carry out an occupation. However, the progress after the CI has different results in some children, because many children are able to interact and participate in society, while others develop limited ability to communicate verbally. The need for a better understanding of CI outcomes, besides hearing and language benefits, has spurred the inclusion of quality of life measurements (QOL) to assess the impact of this technology. OBJECTIVE: Identify the key aspects of quality of life assessed in children with cochlear implant. METHOD: Through a systematic literature review, we considered publications from the period of 2000 to 2011. CONCLUSION: We concluded that QOL measurements in children include several concepts and methodologies. When referring to children using CI, results showed the challenges in broadly conceptualizing which quality of life domains are important to the child and how these areas can evolve during development, considering the wide variety of instruments and aspects evaluated.

Terapia pulpar em dentes decíduos: possibilidades terapêuticas baseadas em evidências

Introduction: Pulpotomy of primary teeth has been the treatment of choice in cases of inflammation of the coronal pulp caused by caries or trauma with no involvement of the radicular pulp, thus avoiding the premature loss of the teeth. Not only is the diagnosis of the inflamed dental pulp required for this therapy to succeed, but also the selection of an effective and biocompatible medicament. However, none of the drugs available and recommended for pulpotomy therapy present all the requirements of an ideal pulp capping agent. Objective: Through a systematic literature review, between the years of 2000 and 2011, focusing in randomized clinical trials, systematic reviews and meta-analysis, aiming to analyze and discuss based on alternatives for the treatment of pulpotomy in human deciduous teeth. Conclusion: Scientific evidences showed that the medicaments and techniques influence were few. Thus, further and well-designed studies are suggested for clarification. The information generated in such experiments may contribute to a better understanding of the mechanisms of pulp therapy to new therapeutic approaches aimed at improving pulp therapy in deciduous teeth.

Radiation therapy for Graves' ophthalmopathy: a systematic review and meta-analysis of randomized controlled trials

PURPOSE: To evaluate the efficacy of radiotherapy (RT) with total dose of 20 Gy (RT 20 Gy) in the treatment of Graves' ophthalmopathy. METHODS: A systematic review and meta-analysis of randomized controlled trials was performed comparing RT 20 Gy with or without glucocorticoid to clinical treatments for Graves' ophthalmopathy. The MEDLINE, EMBASE, Cochrane Library databases and recent relevant journals were searched. Relevant reports were reviewed by two reviewers. Response to radiotherapy was defined as clinical success according to each trial. We also evaluated the quality of life and whether RT to produce fewer side effects than other treatments. RESULTS: A total of 8 randomized controlled trials (439 patients) were identified. In the subgroup analysis, the overall response to treatment rates was better for: RT 20 Gy plus glucocorticoid vs glucocorticoids alone, OR=17.5 (CI95% 1.85-250, p=0.04), RT 20 Gy vs sham RT, OR= 3.15 (CI95%1.59-6.23, p=0.003) and RT 20Gy plus intravenous glucocorticoid vs RT 20Gy plus oral glucocorticoid, OR=4.15(CI95% 1.34-12.87, p=0.01). There were no differences between RT 20 Gy versus other fractionations and RT 20 Gy versus glucocorticoid alone. RT 20 Gy with or without glucocorticoids showed an improvement in diplopia grade, visual acuity, optic neuropathy, lid width, proptosis and ocular motility. No difference was seen for costs, intraocular pressure and quality of life. CONCLUSION: Our data have shown that RT 20 Gy should be offered as a valid therapeutic option to patients with moderate to severe ophthalmopathy. The effectiveness of orbital radiotherapy can be increased by the synergistic interaction with glucocorticoids. Moreover, RT 20 Gy is useful to improve a lot of ocular symptoms, excluding intraocular pressure, without any difference in quality of life and costs.

Mortes evitáveis em vítimas com traumatismos

OBJETIVO: Descrever métodos e estimativas de mortalidade proporcional por mortes evitáveis e tipos de não conformidades do atendimento relacionadas a esses eventos. MÉTODOS: Revisão sistemática de publicações sobre mortes evitáveis em vítimas com traumatismos entre 2000 e 2009. Foi realizada pesquisa nas bases de dados Lilacs, SciELO e Medline utilizando-se a estratégia de busca com as palavras-chave "trauma", "avoidable", "preventable", "interventions" e "complications", e os descritores em ciências da saúde "death", "cause of death" e "hospitals". RESULTADOS: Identificaram-se 29 artigos publicados no período, com predomínio de estudos retrospectivos (96,5%). Os métodos mais comumente utilizados para definir a evitabilidade do óbito foram painel de especialistas ou pontuação de índices de gravidade, tendo sido empregadas as seguintes categorias: evitável, potencialmente evitável e não evitável. A média da mortalidade proporcional por mortes evitáveis dos estudos foi de 10,7% (dp 11,5%). As não conformidades mais comumente relatadas nas publicações foram sistema inadequado de atendimento ao traumatizado e erro na avaliação e tratamento. CONCLUSÕES: Observaram-se falhas na uniformização dos termos empregados para categorizar as mortes e as não conformidadades encontradas. Portanto, sugere-se a padronização da taxonomia da classificação das mortes e dos tipos de não conformidades observadas.

Práticas baseadas em evidências publicadas no Brasil: identificação e reflexão na área da prevenção em saúde humana

Revisão integrativa de estudos brasileiros sobre práticas baseadas em evidências (PBE) acerca da prevenção em saúde humana, publicados em periódicos Web of Science/JCR, de outubro de 2010 a abril de 2011. O objetivo foi identificar as especialidades que mais realizaram estes estudos, seus enfoques e abordagens metodológicas. A partir de critérios de inclusão, foram selecionados 84 trabalhos publicados majoritariamente em periódicos de saúde pública, focalizando a atenção primária e abrangendo também questões clínicas e diversas especialidades. Variaram também os enfoques de prevenção e as abordagens metodológicas, predominando a revisão sistemática sem metanálise. Os resultados indicam que não há uma única maneira de conceituar e praticar a PBE na prevenção e sua aplicação pode não ser apenas para obtenção de prova irrefutável para instrumentalizar ações de intervenção. Constitui um campo infindável de conhecimentos, em construção, para análise e maior compreensão de fenômenos em saúde.

Diferenças de gênero sobre expectativas do uso de álcool

CONTEXTO: Estudos indicam que expectativas sobre o uso de álcool podem contribuir para o início e a manutenção do consumo da droga e modular de forma diferente o comportamento do beber de homens e de mulheres. OBJETIVOS: Descrever e analisar diferenças de gênero sobre expectativas relacionadas ao uso de álcool em artigos da literatura indexada. MÉTODOS: Foram pesquisados artigos empíricos originais no período de 2000 a 2011 nos indexadores PubMed, SciELO, Lilacs e PsycInfo. RESULTADOS: Foram selecionados 32 estudos, sendo apenas dois de origem latino-americana. Expectativa de facilitação social foi a mais observada para ambos os gêneros. Homens apresentaram maior diversidade de expectativas sobre os efeitos do uso de álcool. Intervenções baseadas na redução de expectativas positivas parecem mais eficazes entre os homens. CONCLUSÃO: Expectativas são um importante fator de risco para o uso de álcool, independentemente do gênero. A consideração das diferenças de gênero sobre expectativas pode beneficiar o manejo clínico de problemas associados ao consumo de álcool e direcionar ações preventivas para o risco de abuso e dependência.

Contributions from the systematic review of economic evaluations: the case of childhood hepatitis A vaccination in Brazil

The aim of this study was to present the contributions of the systematic review of economic evaluations to the development of a national study on childhood hepatitis A vaccination. A literature review was performed in EMBASE, MEDLINE, WOPEC, HealthSTAR, SciELO and LILACS from 1995 to 2010. Most of the studies (8 of 10) showed favorable cost-effectiveness results. Sensitivity analysis indicated that the most important parameters for the results were cost of the vaccine, hepatitis A incidence, and medical costs of the disease. Variability was observed in methodological characteristics and estimates of key variables among the 10 studies reviewed. It is not possible to generalize results or transfer epidemiological estimates of resource utilization and costs associated with hepatitis A to the local context. Systematic review of economic evaluation studies of hepatitis A vaccine demonstrated the need for a national analysis and provided input for the development of a new decision-making model for Brazil.

A systematic review of mercury ototoxicity

Mercury is neurotoxic, and numerous studies have confirmed its ototoxic effect. However, the diagnosis and follow-up of mercury exposure require understanding the pathophysiology of the chemical substance. Based on a systematic literature review, this study aimed to demonstrate whether mercury is ototoxic and to analyze its mechanism of action on the peripheral and central auditory system, in order to contribute to the diagnosis and follow-up of exposure. This was a systematic review of studies published on the effects of mercury exposure on the auditory system. The full text of the studies and their methodological quality were analyzed. The review identified 108 studies published on the theme, of which 28 met the inclusion criteria. All the articles in the analysis showed that mercury exposure is ototoxic and produces peripheral and/or central damage. Acute and long-term exposure produces irreversible damage to the central auditory system. Biomarkers were unable to predict the relationship between degree of mercury poisoning and degree of lesion in the auditory system.

Active cutaneous warming systems to prevent intraoperative hypothermia: a systematic review

This study analyzed the evidence available in the literature concerning the effectiveness of different active cutaneous warming systems to prevent intraoperative hypothermia. This is a systematic review with primary studies found in the following databases: CINAHL, EMBASE, Cochrane Register of Controlled Trials and Medline. The sample comprised 23 randomized controlled trials. There is evidence in the literature indicating that the circulating water garment system is the most effective in maintaining patient body temperature. These results can support nurses in the decision-making process concerning the implementation of effective measures to maintain normothermia, though the decision of health services concerning which system to choose should also take into account its cost-benefit status given the cost related to the acquisition of such systems.

Knowledge management in health: a systematic literature review

Knowledge has been used as a resource for intelligent and effective action planning in organizations. Interest in research on knowledge management processes has intensified in different areas. A systematic literature review was accomplished, based on the question: what are the contributions of Brazilian and international journal publications on knowledge management in health? The sample totaled 32 items that complied with the inclusion criteria. The results showed that 78% of journals that published on the theme are international, 77% of researchers work in higher education and 65% have a Ph.D. The texts gave rise to five thematic categories, mainly: development of knowledge management systems in health (37.5%), discussion of knowledge management application in health (28.1%) and nurses' function in knowledge management (18.7%).
