The aim of this work is to analyze the analogy between the episode Nosedive from the Black Mirror series and reality: how social networks can interfere in the behavior, psyche and relationships of the individual in the contemporary society. The research starts from a narrative film analysis of the cited episode, based mainly on the studies of theorists Bauman and Debord on society. The work was divided into three chapters: the first is intended for the conceptualization of the series, the passage from the TV format to the streaming model and the themes that are addressed by Black Mirror. The second will bring the presentation and definition of social networks, the reflections of the use of interaction media and how connections are being established and affected by the virtualization of relationships. In the third chapter, the analysis occurs through the description of the scenes, correlating with the aspects of postmodern society and with the theories brought in chapters one and two. Finally, it was possible to establish affinities between the dystopian universe and the physical world to which people are inserted.

O acompanhamento do paciente crítico é uma das áreas mais complexas e que requerem atenção, portanto, é clara a necessidade de uma equipe de enfermagem capacitada dentro do atendimento da Unidade de Terapia Intensiva, tanto realizando monitorização quanto procedimentos. Objetivo: Apresentar evidências na literatura acerca dos principais dispositivos utilizados para monitoramento hemodinâmico dentro da UTI e da capacitação da equipe de enfermagem no tratamento de pacientes críticos. Metodologia: Foi realizada uma pesquisa de revisão integrativa. Foram utilizados os descritores “monitorização”, “hemodinâmica”, “enfermagem” e “UTI” combinados pelo operador booleano AND, nas bases de dados eletrônicas SCIELO, BDENF e LILACS. Resultados: Foram selecionados 10 estudos, destes, publicados no período de 2008 a 2019, e em sua maioria são do tipo bibliográfico, com Qualis CAPES entre A1 e B1. Discussão: Sendo a Unidade de Terapia Intensiva um setor de alta complexidade e variedade de meios de monitorização, é importante entender a enfermagem como meio de atuação essencial para a reversão do quadro do paciente e que deve estar capacitada para a manutenção e funcionamento dos equipamentos utilizados. Conclusão: O conhecimento vasto do enfermeiro sobre o monitoramento eficaz e efeitos adversos esperados é primordial no socorro imediato, melhorando a qualidade da assistência.

The colors by pair, one of the indicators of the Pfister test, are pre-established combinations of two colors that, when used together, suggest interpretations about emotional dynamics. We looked for validity evidence based on relations with other variables for the use of colors by pair with children. In the Pfister protocols of children between 6 and 11 years, the four most frequent colors by pair were Vd↓Vm↑, La↓Vi↓, Vm↑Br↑ and Vm↑Pr↑. When we compare the protocols of 172 children by age, older children tend to have more colors by pair than the younger children. In addition, we compared the results of the Zulliger test of these children according to presence or absence of the most frequent colors by pair. There were few differences in Zulliger’s performance associated with the colors by pair of the TPC, and more research is needed to understand the meaning of this indicator.

Abstract Objective The “Self-report S4-5 sensory and motor function questionnaire (S4-5Q)” is a short questionnaire that aims to assess the function of the sacral segments, S4 and S5, after a spinal cord injury (SCI), with the purpose of replacing the rectal exam test. The aim of the present study was to carry out a cross-cultural adaptation of the S4-5Q to the Brazilian Portuguese language and to investigate the test-retest reliability of this version. Method The translation and cross-cultural adaptation was performed using the methodology of translation and backtranslation. Initially, translations were done by three independent translators. Their synthesis was then submitted to an expert committee for analysis (SCI health professionals); then, the backtranslation to the original language was sent to the original author and, after all the adjustments, the final version was completed. For test-retest reliability, 24 individuals with chronic SCI were recruited (2 evaluations with an interval of 7 to 14 days between them). Statistical analysis was performed using IBM-SPSS (Version 20, SPSS Inc, Chicago, IL, USA) with data pretabulated in Microsoft Excel (Microsoft Corporation, Redmond, WA, USA). Reliability was tested with Cohen Kappa, and internal consistency with Cronbach α, both adopting p < 0.05 as significant. Results In the reliability analysis, the results of all questions showed almost perfect agreement (Kappa > 0.81) and good internal consistency (Cronbach α: 0.65-0.77) between the questions and final classification. Conclusion The cross-culturally adapted S4-5Q is reliable to be applied to the Brazilian population with chronic SCI to determine their S4-5 sensory and motor function.

The present study aims the development and application of an electrochemical method for simple coumarin determination in aqueous media by using a boron-doped diamond electrode (BDDE). The studies were carried out at pH 8.0 by cyclic voltammetry (CV) and registered an irreversible reduction process controlled by diffusion with the peak potential recorded around -1.6 V. The square wave voltammetry analysis (SWV) showed the reversible behavior of the electrochemical reduction of coumarin at the same pH. Additionally, the reversibility of the process was improved by increasing the solution pH. The chronoamperometry study showed that the coumarin reduction process involves two electrons. From the optimized SWV parameters, the analytical curve was constructed in a linear range between 0.5 × 10-5 and 10.0 × 10-5 mol L-1. The limits of detection and quantification were 1.5 × 10-6 mol L-1 and 4.5 × 10-6 mol L-1, respectively. The coumarin was determined in an aqueous infusion of Mikania glomerata, showing recovery values between 92 and 104%.

Multilayer graphene (G-US) and multilayer graphene muffled (Gm-US) produced by liquid exfoliation ultrasound were used as support for Pd nanoparticles with a load of 20 wt% for application in an alkaline direct ethanol fuel cell (ADEFC) anode. The multilayer graphene–based electrocatalyst (Pd/G-US) exhibited superior current density and less positive onset potential for ethanol oxidation reaction (EOR) than the commercial Pd/C (AA). Also, the Pd/G-US electrocatalyst showed the less positive onset potential for CO oxidation. In ADEFC experiments, the Pd/G-US catalyst exhibited a superior performance with 38 mW cm−2. The findings suggest that the defective graphene structure promotes electron transport, and the presence of oxygenated species increases hydrophilicity facilitating the oxidation of intermediates. Hence, the synthesized material can be considered as promising support for an anode in ADEFC. Graphical abstract: [Figure not available: see fulltext.]

Resumo Objetivo Identificar na literatura nacional e internacional, estudos sobre a eficácia de métodos não farmacológicos na redução da dor do parto. Métodos Revisão integrativa realizada nas bases de dados MEDLINE/PUBMED, SCOPUS, CINAHL, LILACS e BDENF, com recorte temporal entre os anos de 2013 a 2018, em português, inglês e espanhol. Utilizado a metodologia PICo para construir a pergunta de pesquisa e selecionar descritores controlados e não controlados, que foram combinados com os operadores booleanos “AND”, “OR” e “NOT”. Resultados Foram selecionados 19 artigos. Dentre os métodos não farmacológicos encontrados, destacam-se: a acupuntura e suas principais variações (acupressão e auriculoterapia) (29,17%), hidroterapia (25%), exercícios perineais com a bola suíça (16,67%), terapias térmicas (8,33%) e os demais métodos (20,83%). Conclusão A acupuntura e a acupressão agem tanto sobre aspectos fisiológicos da dor como sobre sua subjetividade. O banho quente de aspersão, a musicoterapia, a aromaterapia e as técnicas de respiração promovem o relaxamento e a diminuição dos níveis de ansiedade. As terapias térmicas contribuem para a analgesia local de regiões afetadas pela dor. Os exercícios na bola suíça são importantes para reduzir a dor e adotar a posição vertical, importante na progressão do trabalho de parto.
