New carioca bean cultivars are being introduced into the market necessitating their evaluation under trade conditions, which often require storage under ambient conditions. We therefore evaluated the darkening and hardening processes of six carioca bean genotypes each representing regular and slow darkening trait during storage under ambient conditions for five months to elucidate their relationship as a breeding strategy. Storage time adversely affected color characteristics (L*, a*, b*, C* and ΔE) depending on bean genotype, whereas hardness and resistance to cooking increased during storage independent of the lignification process. Bean darkening and hardening occurred during storage at different intensities in each genotype and were not always correlated. BRSMG-Madrepé rola, a slow darkening genotype, was unaffected (resistant to storage conditions), whereas BRS-Pontal with regular tegument darkening, was highly susceptible to storage conditions reflected in extended cooking time and darkening (low L* values). Principal component and cluster analyses on 8 constituents analyzed in this study demonstrate the difference in color characteristics, cooking time and hardness as major factors in segregating the bean genotypes. Seed coat color is an important but inappropriate single parameter for predicting the resistance to cooking or hardness induced by storage of carioca beans under ambient conditions. Development of carioca bean genotypes resistant to storage conditions is essential in reducing food losses during postharvest.

This study aims to evaluate tissue healing efficacy in burn patients treated with 1% silver sulfadiazine versus other treatments. This is a systematic literature review and meta-analysis of randomized clinical trials performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyzes (PRISMA) and PICO strategy, registered in the International Prospective Register of Systematic Reviews (PROSPERO) under the number CRD42017081057. The review found 71 studies in MEDLINE/Pubmed, 1 in Clinical Trials, 19 in the Cochrane Library, and 4 in LILACS in five manual searches. Of these, 81 studies were pre-selected. After independent analysis by two reviewers, only 11 studies met the inclusion criteria for the review. All studies (n = 11) using alternative treatments to silver sulfadiazine were shown to be superior in the mean time for complete wound healing, with statistically significant differences between experimental and control groups (p <0.00001); mean difference (- 4.26), 95% CI [- 5.96, - 2.56].

Objetivo: Levantar as medidas preventivas utilizadas para diminuir o risco de Pneumonia por Ventilação Mecânica na Unidade de Terapia Intensiva. Metodologia: Trata-se de uma revisão integrativa da literatura na qual foram consideradas as seguintes etapas de seleção: identificação da questão da pesquisa, busca na literatura, categorização e avaliação dos estudos, interpretação dos resultados e síntese do conhecimento, sendo selecionados para esta pesquisa artigos publicados entre os anos de 2011 a 2017. Resultados: Foram localizados 108 artigos sendo 101 na base Pubmed e 7 na base de dados Literatura Latino Americana, por meio de cruzamento dos descritores. Após exclusão a partir do título foram selecionados 25 artigos, estes passaram por leitura na íntegra, excluindo-se os duplicados. A amostra obteve um total de 7 artigos que assim entraram nesta revisão de literatura. Conclusão: Os resultados evidenciam que as principais ações para prevenção da Pneumonia por Ventilação Mecânica é a assepsia, seja por higiene das mãos ou por limpeza dos conectores dos ventiladores.Descritores: Ventilação Mecânica; Enfermagem; Pneumonia; Cuidados Intensivos.
