Semantic equivalence of the Portuguese version of the Abuse Assessment Screen tool used for the screening of violence against pregnant women

Abstract: INTRODUCAO: Programas de investigacao epidemiologica e de acao no âmbito da violencia familiar estao em franca ascensao, requerendo instrumentos de afericao adaptados e vertidos para o portugues. O objetivo do estudo e avaliar a equivalencia semântica entre o original em ingles e duas versoes para o portugues do instrumento Abuse Assessment Screen (AAS) usado no rastreamento de casos de violencia contra a mulher gravida e recomendar uma versao-sintese para uso corrente. METODOS: O processo de avaliacao de equivalencia semântica envolveu quatro etapas: traducao, retraducao, apreciacao formal de equivalencia e critica final atraves de consultas com especialista na area tematica. RESULTADOS: Para cada item do instrumento apresentam-se os resultados relativos as quatro etapas. O texto cobre cada passo do processo que levou a versao final. As duas versoes mostraram-se bastante semelhantes, com 14 das 15 assertivas similares, embora a segunda versao tenha se mostrado mais adequada, ainda que para alguns itens tenha sido decidido juntar as duas versoes ou mesmo utilizar um item oriundo da versao um. CONCLUSAO: E importante usar mais de uma versao no processo, em varias etapas de avaliacao e de critica, e discutir a pertinencia de se acrescentar uma etapa adicional de interlocucao do instrumento com membros da populacao-alvo.

Risk factors for new-onset diabetes mellitus in adult liver transplant recipients, an analysis of the Organ Procurement and Transplant Network/United Network for Organ Sharing database.

Abstract: OBJECTIVE.: To analyze the risk factors for new-onset diabetes mellitus (NODM) in liver transplant recipients using the Organ Procurement and Transplant Network/United Network for Organ Sharing database. METHODS.: Among 20,172 primary liver recipients (age > or =18 years) transplanted between July 2004 and December 2008 in Organ Procurement and Transplant Network/United Network for Organ Sharing databases, 15,463 recipients without pretransplant diabetes were identified. Risk factors for NODM were examined using multivariate Cox regression analysis. RESULTS.: NODM was reported in 26.4% of recipients (median follow-up, 685 days). Independent predictors of NODM development included recipient age (> or = 50 vs. or = 25 vs. or = 60 vs. <60 year, HR=1.152), diabetic donor (HR=1.151), tacrolimus (tacrolimus vs. cyclosporine, HR=1.236), and steroid at discharge (HR=1.594). Living donor transplant (HR=0.628) and induction therapy (HR=0.816) were associated with a decreased risk of NODM. CONCLUSION.: The incidence of NODM was 26.4% in liver recipients with a median follow-up time of 685 days. Identified risk factors for NODM in liver transplantation were similar to that in kidney transplantation. Some of the identified factors are potentially modifiable, including obesity and the choice of immunosuppressive regimens.

Engineering a future for amphibians under climate change

Abstract: 1. Altered global climates in the 21st century pose serious threats for biological systems and practical actions are needed to mount a response for species at risk. 2. We identify management actions from across the world and from diverse disciplines that are applicable to minimizing loss of amphibian biodiversity under climate change. Actions were grouped under three thematic areas of intervention: (i) installation of microclimate and microhabitat refuges; (ii) enhancement and restoration of breeding sites; and (iii) manipulation of hydroperiod or water levels at breeding sites. 3. Synthesis and applications. There are currently few meaningful management actions that will tangibly impact the pervasive threat of climate change on amphibians. A host of potentially useful but poorly tested actions could be incorporated into local or regional management plans, programmes and activities for amphibians. Examples include: installation of irrigation sprayers to manipulate water potentials at breeding sites; retention or supplementation of natural and artificial shelters (e.g. logs, cover boards) to reduce desiccation and thermal stress; manipulation of canopy cover over ponds to reduce water temperature; and, creation of hydrologoically diverse wetland habitats capable of supporting larval development under variable rainfall regimes. We encourage researchers and managers to design, test and scale up new initiatives to respond to this emerging crisis. © 2011 The Authors. Journal of Applied Ecology

Search for the standard model Higgs boson decaying to W + W - in the fully leptonic final state in pp collisions at √{ s} = 7 TeV

Abstract: A search for the standard model Higgs boson decaying to W+W- in pp collisions at sqrt(s) = 7 TeV is reported. The data are collected at the LHC with the CMS detector, and correspond to an integrated luminosity of 4.6 inverse femtobarns. The W+W- candidates are selected in events with two charged leptons and large missing transverse energy. No significant excess of events above the standard model background expectations is observed, and upper limits on the Higgs boson production relative to the standard model Higgs expectation are derived. The standard model Higgs boson is excluded in the mass range 129-270 GeV at 95% confidence level.
