    BACKGROUND: The use of antiviral medications by HIV negative people to prevent acquisition of HIV or pre-exposure prophylaxis (PrEP) has shown promising results in recent trials. To understand the potential impact of PrEP for HIV prevention, in addition to efficacy data, we need to understand both the acceptability of PrEP among members of potential user groups and the factors likely to determine uptake. METHODS AND FINDINGS: Surveys of willingness to use PrEP products were conducted with 1,790 members of potential user groups (FSWs, MSM, IDUs, SDCs and young women) in seven countries: Peru, Ukraine, India, Kenya, Botswana, Uganda and South Africa. Analyses of variance were used to assess levels of acceptance across different user groups and countries. Conjoint analysis was used to examine the attitudes and preferences towards hypothetical and known attributes of PrEP programs and medications. Overall, members of potential user groups were willing to consider taking PrEP (61% reported that they would definitely use PrEP). Current results demonstrate that key user groups in different countries perceived PrEP as giving them new possibilities in their lives and would consider using it as soon as it becomes available. These results were maintained when subjects were reminded of potential side effects, the need to combine condom use with PrEP, and for regular HIV testing. Across populations, route of administration was considered the most important attribute of the presented alternatives. CONCLUSIONS: Despite multiple conceivable barriers, there was a general willingness to adopt PrEP in key populations, which suggests that if efficacious and affordable, it could be a useful tool in HIV prevention. There would be a willingness to experience inconvenience and expense at the levels included in the survey. The results suggest that delivery in a long lasting injection would be a good target in drug development

    OBJETIVO: O reanimador manual autoinflável é um dispositivo que fornece ventilação com pressão positiva. Pesquisas mostram que, apesar da padronização dos reanimadores manuais autoinfláveis pela American Society for Testing and Materials, diversos fatores afetam o desempenho da ventilação, porém, os resultados são conflitantes. O objetivo desse estudo foi verificar as evidências dos fatores que influenciam a ventilação pulmonar com reanimadores manuais infantil/adulto por meio de uma revisão sistemática da literatura. FONTES DE DADOS: Foram incluídos artigos indexados nas bases Medline, Lilacs e SciELO publicados entre janeiro de 1986 e março de 2011. Utilizaram-se as palavras-chaves: "reanimador manual", "ressuscitador manual", "ventilação manual", "ventilação com pressão positiva", em inglês e português, além de "bag-valve". SÍNTESE DOS DADOS: Foram selecionados 45 artigos, sendo a maioria experimental. Os trabalhos compararam os reanimadores manuais por marcas, modelos e analisaram as características dos profissionais que os utilizam. Estudos verificaram que a eficácia da ventilação com os reanimadores manuais depende da marca, modelo e características funcionais do aparelho utilizado, assim como formação, treinamento e experiência do profissional que os manipula. Outros fatores que podem influenciar são a forma de compressão dos reanimadores manuais, o uso da válvula limitadora de pressão e o fluxo de oxigênio fornecido aos aparelhos. CONCLUSÕES: A variabilidade nos parâmetros ventilatórios fornecidos durante a ventilação com reanimadores manuais não permite uniformizar a técnica, o que prejudica a reanimação cardiopulmonar. Apesar da maioria dos reanimadores manuais parecer estar de acordo com padrões internacionais, os equipamentos devem ser avaliados antes de utilizados no ambiente clínico. Pouco se sabe sobre os modelos pediátricos e neonatais.<br>OBJECTIVE: The manual resuscitator (RM) is a device that provides positive pressure ventilation. Surveys conducted to assess the adequacy of manual resuscitators to American Society for Testing and Materials standards show that several factors affect manual ventilation. However, results are conflicting. The aim of this study was to verify evidence of factors that influence pediatric/adult pulmonary ventilation with manual resuscitator by a systematic review. DATA SOURCE: Original articles indexed in Medline, Lilacs and SciELO published from January 1986 to March 2011. The key-words used were: "manual resuscitator", "manual ventilation", "positive pressure ventilation" in Portuguese and English, as well as "bag-valve". DATA SYNTHESIS: 45 articles were selected, most of them experimental. The studies compared manual resuscitator brands and models, and analyzed the physical characteristics of professionals. The effectiveness of ventilation with manual resuscitator depends on the brand, model and functional characteristics of the equipment. Ventilation also varies with the education, training and experience of the professional who handles the equipment. Other factors that can influence effectiveness are the manual resuscitator compression form, the use of a pressure relief valve and the flow of oxygen provided to the manual resuscitator. CONCLUSIONS: The variability of ventilatory parameters during manual resuscitation does not allow a standardization of the technique, being harmful to cardiopulmonary resuscitation. Although most manual resuscitator seem to follow international standards, the equipment must be evaluated in the clinical settings. There are few studies about pediatric and neonatal manual resuscitator models
