    <p>Abstract</p> <p>Background</p> <p>The purpose of this study was to conduct a scoping review of the literature about the establishment and impact of quality and safety team initiatives in acute care.</p> <p>Methods</p> <p>Studies were identified through electronic searches of Medline, Embase, CINAHL, PsycINFO, ABI Inform, Cochrane databases. Grey literature and bibliographies were also searched. Qualitative or quantitative studies that occurred in acute care, describing how quality and safety teams were established or implemented, the impact of teams, or the barriers and/or facilitators of teams were included. Two reviewers independently extracted data on study design, sample, interventions, and outcomes. Quality assessment of full text articles was done independently by two reviewers. Studies were categorized according to dimensions of quality.</p> <p>Results</p> <p>Of 6,674 articles identified, 99 were included in the study. The heterogeneity of studies and results reported precluded quantitative data analyses. Findings revealed limited information about attributes of successful and unsuccessful team initiatives, barriers and facilitators to team initiatives, unique or combined contribution of selected interventions, or how to effectively establish these teams.</p> <p>Conclusions</p> <p>Not unlike systematic reviews of quality improvement collaboratives, this broad review revealed that while teams reported a number of positive results, there are many methodological issues. This study is unique in utilizing traditional quality assessment and more novel methods of quality assessment and reporting of results (SQUIRE) to appraise studies. Rigorous design, evaluation, and reporting of quality and safety team initiatives are required.</p

    Lawson criterion for ignition exceeded in an inertial fusion experiment

    For more than half a century, researchers around the world have been engaged in attempts to achieve fusion ignition as a proof of principle of various fusion concepts. Following the Lawson criterion, an ignited plasma is one where the fusion heating power is high enough to overcome all the physical processes that cool the fusion plasma, creating a positive thermodynamic feedback loop with rapidly increasing temperature. In inertially confined fusion, ignition is a state where the fusion plasma can begin "burn propagation" into surrounding cold fuel, enabling the possibility of high energy gain. While "scientific breakeven" (i.e., unity target gain) has not yet been achieved (here target gain is 0.72, 1.37 MJ of fusion for 1.92 MJ of laser energy), this Letter reports the first controlled fusion experiment, using laser indirect drive, on the National Ignition Facility to produce capsule gain (here 5.8) and reach ignition by nine different formulations of the Lawson criterion

    OBJETIVO: Verificar se a área dos orifícios velofaríngeos obtida após o retalho faríngeo (RF) durante a respiração de repouso (AVFr) é um indicador do grau de fechamento velofaríngeo durante a fala (AVFf). MÉTODOS: Os sujeitos foram 62 pacientes com fissura de palato, associada ou não à fissura de lábio, de ambos os gêneros, com idades entre seis e 32 anos, submetidos ao RF há, pelo menos, 12 meses. AVFr e AVFf foram determinadas por meio da técnica fluxo-pressão. Valores de AVFr inferiores a 0,500 cm² foram considerados subnormais. A AVFf foi classificada como adequada (0-0,049 cm²), marginal (0,050-0,199 cm²) ou inadequada (>0,200 cm²). A associação entre os valores de AVFr e AVFf pós-cirúrgicos foi analisada por meio de um modelo de regressão logística. RESULTADOS: Após o RF, 92% dos pacientes com valores de AVFr subnormais (<0,500 cm²) apresentaram fechamento velofaríngeo adequado. A proporção de pacientes com valores de AVFr normais (>0,500 cm²) e fechamento velofaríngeo adequado foi menor, porém ainda expressiva (55%). Não houve associação estatisticamente significante entre as duas variáveis. CONCLUSÃO: A maioria dos pacientes com retalho largo apresentou fechamento velofaríngeo adequado durante a fala. Entretanto, os resultados mostraram que as dimensões dos orifícios velofaríngeos durante a respiração de repouso não podem predizer a eficácia do retalho faríngeo para a fala.<br>PURPOSE: To investigate whether postoperative velopharyngeal orifice area during nasal breathing at rest (VPAb) can predict velopharyngeal closure during speech (VPAs). METHODS: The subjects were 62 patients with cleft palate, associated or not with cleft lip, of both genders, with ages between six and 32 years, who underwent pharyngeal flap surgery (PFS) at least 12 months before the evaluation performed for this study. VPAb and VPAs were assessed using the pressure-flow technique. VPAb values below 0.500cm² were considered subnormal. VPAs was categorized as adequate (0-0.049cm²), borderline (0.050-0.199cm²) or inadequate (>0.200cm²). A logistic regression model analyzed the association between VPAb and VPAs. RESULTS: After PFS, 92% of the patients with subnormal VPAb values (<0.500cm²) presented adequate velopharyngeal closure. The percentage of patients with normal VPAb values (>0.500cm²) who also presented adequate closure was smaller, but still significant (55%). The association between VPAb and VPAs values was not statistically significant. CONCLUSION: Most patients with large flaps presented adequate velopharyngeal closure during speech. However, the findings show that the velopharyngeal orifice area during breathing is not a good predictor of the effectiveness of the pharyngeal flap for speech
