Comparative analysis of volatile and phenolic composition of alternative wood chips from cherry, acacia and oak for potential use in enology.

The aim of present work was to investigate the phenolic and volatile composition of cherry, acacia, and oak (from different species) wood chips. By the use of HPLC-DAD 18 different phenolic compounds were detected and quantified while for volatile composition, 33 different compounds were detected by GC-MS. In general, wood samples from oak species showed the higher number of phenolic compounds detected, while cherry wood samples showed the lowest levels. In addition, some individual phenolic compounds were detected, specifically in some wood samples, such as robinetin in acacia woods and naringenin in cherry wood. For volatile composition, cherry wood chips samples showed the lowest volatile composition followed by increasing order by acacia, French, Portuguese and American wood chip samples. Oak wood chip samples from American species showed the highest volatile content, as a result of high levels of several specific compounds (furfural, 5-methyfurfural, β-methyl-γ-octalactones, guaiacol, vanillin and siringaldehyde).

Clinical communication and adverse health events: literature review

Abstract Health institutions have an increased risk of occurrence of errors due to their diversity, specificity and volume of services, representing a great concern for health professionals whose main function is to protect the health and lives of their patients. We intend to identify a body of evidence, that shows what the most common adverse events are and what adverse events potentially arise from clinical miscommunications. An integrative literature review using the keywords "Adverse Events", "Patient Safety", "Communication". An inquiry was made on databases PubMed, Web of Science, Scielo and CINAHL, in articles published between January 2010 and March 2016, available in Portuguese and English. Of the 216 articles that emerged were selected eight articles that answered the research questions: what are the most common adverse events that have their origin in communication errors? Analyzing the selected studies, it appears that the most common adverse events arise in the context of obstetrics and pediatrics, in surgical contexts, in the continuity of care and related medication. Patient safety should be seen as a key component of quality in health care, with good management of the risk of fundamental error for the promotion of this security. The knowledge and understanding that communication failures are one of the main factors contributing to the occurrence of errors in the context of health care, allows the subsequent development of strategies to improve this process and thus ensure safer healthcare.

A segurança e qualidade dos cuidados : revisão da literatura

A segurança é um princípio fundamental nos cuidados prestados e exige um complexo sistema de sinergias e um amplo leque de ações para a melhoria da qualidade. É indiscutível que a ocorrência de erros cria uma preocupação constante para os profissionais, sendo primordial fomentar uma cultura de segurança. Este artigo tem por objetivo identificar os fatores determinantes na segurança e qualidade dos cuidados de Enfermagem. Realizou-se uma revisão da literatura, utilizando descritores “Segurança do doente”, “Cultura de Segurança”, “Enfermagem”, “Qualidade dos Cuidados”, emergindo 309 artigos. Efetou-se uma pesquisa na PubMed, SciELO, Web of Science, com artigos publicados entre janeiro de 2010 e março de 2016. Foram selecionados 11 artigos que respondiam à questão de investigação “Quais os fatores determinantes da segurança e qualidade dos cuidados de Enfermagem?“. Dos 11 artigos seleccionados emergiram duas temáticas: a consciencialização do erro e a criação de uma cultura de segurança nas organizações. Este estudo evidencia que a ocorrência de erros constitui uma ameaça à qualidade dos cuidados e segurança dos utentes, contudo, a consciencialização dos riscos e a aplicação de medidas para o desenvolvimento de uma cultura de segurança contribui para a diminuição da frequência e severidade dos erros nas instituições de saúde.
