ABSTRACT Objective: to analyze the characteristics of the activation of the yellow code in wards and identify the factors associated with adverse events after the Rapid Response Team. Methods: a cross-sectional study with retrospective analysis of medical records of adults admitted to medical or surgical clinic wards of the University Hospital of São Paulo. Results: among the 91 patients, the most frequent signs of triggers (n=107) were peripheral oxygen saturation of less than 90% (40.2%) and hypotension (30.8%). Regarding the associated factors the research identified each minute of attendance of the Rapid Response Team in the wards increased by 1.2% odds of adverse events (twenty-four unplanned admission in the ICU and one cardiac arrest) in the sample (p=0.014). Conclusions: decreased oxygen saturation and hypotension were the main reasons for the triggering, and the length of care was associated with the frequency of adverse events.

RESUMEN Objetivo: analizar características de la activación del código amarillo en unidades de internación e identificar factores relacionados a ocurrencia de eventos adversos después de la atención del Equipo de Respuesta Rápida. Métodos: estudio transversal con análisis retrospectivo de prontuarios de adultos internados en enfermerías de Clínica Médica o Quirúrgica de hospital universitario de São Paulo. Resultados: entre 91 pacientes, los signos más frecuentes de las activaciones (n=107) fueron saturación periférica de oxígeno inferior a 90% (40,2%) y hipotensión arterial (30,8%). Cuanto a factores relacionados, identificado que cada minuto de atención del Equipo de Respuesta Rápida en enfermerías aumentó en 1,2% la chance de ocurrencia de eventos adversos (24 admisiones no planeadas en Unidad de Cuidado Intensivo y un paro cardíaco) en la amuestra (p=0,014). Conclusiones: caída de saturación de oxígeno e hipotensión arterial fueron los principales motivos de activación, y tiempo de ateción fue relacionado a ocurrencia de eventos adversos.

RESUMO Objetivo: analisar as características do acionamento do código amarelo em unidades de internação e identificar os fatores associados à ocorrência de eventos adversos após o atendimento do Time de Resposta Rápida. Métodos: estudo transversal com análise retrospectiva de prontuários de adultos internados em enfermarias de Clínica Médica ou Cirúrgica de hospital universitário de São Paulo. Resultados: entre os 91 pacientes, os sinais mais frequentes dos acionamentos (n=107) foram saturação periférica de oxigênio inferior a 90% (40,2%) e hipotensão arterial (30,8%). Quanto aos fatores associados, identificou-se que cada minuto de atendimento do Time de Resposta Rápida nas enfermarias aumentou em 1,2% a chance de ocorrência de eventos adversos (24 internações não planejadas em Unidade de Terapia Intensiva e uma parada cardiorrespiratória) na amostra (p=0,014). Conclusões: queda da saturação de oxigênio e hipotensão arterial foram os principais motivos de acionamento, e o tempo de atendimento foi associado à ocorrência de eventos adversos.

ABSTRACT We sought to develop a typology describing structural, production, and socioeconomic characteristics of dairy systems that produce artisanal cheese and compare it with that of systems that produce only raw milk. Data on 204 raw milk producers and 58 artisanal cheese producers in Paraná State, Brazil, were collected through on-site surveys and subjected to descriptive analysis, factor analysis, and means tests. Descriptive analyses were applied to characterize the sample and artisanal cheese production processes. Factor analysis identified the following three typological components: system production capacity, herd breed and milking characteristics, and farmer social characteristics. Farmers were divided into two groups, as follows: non-cheese producers (NCP) and artisanal cheese producers (ACP). Groups of farmers were compared in terms of typological components. It was found that ACP have smaller structure and production scale and focus less on herd breed and practices for improving milk quality than NCP. These results suggest that artisanal cheese production is a strategy to add value to milk that does not meet institutional or market requirements for transactions with the dairy industry, providing a foothold for producers to remain in the dairy business. Groups of farmers (ACP and NCP) do not differ in social indicators of typology.

ABSTRACT Extrapulmonary tuberculosis associated with immune thrombocytopenia (ITP) is extremely rare. A likely association between ITP and pulmonary and lymph node tuberculosis was reported in a 29-year-old male patient. His platelet count decreased to 4,000/µL. Chest tomography revealed mediastinal adenomegaly, lymph node clusters in the aorta, and consolidation in the left upper lung lobe. Immunoglobulin and methylprednisolone were administered intravenously. The histopathology of the left upper lung lobe confirmed tuberculosis. The rifampicin/isoniazid/pyrazinamide/ethambutol regimen was initiated, and the corticosteroids were tapered off. This case suggests an association of tuberculosis with ITP, since the platelet count effectively normalized after tuberculosis treatment.

Abstract Objective The use of a fiber glass post (FGP) type and choice of FGP diameter to restore endodontically treated incisors without ferrule is controversial. This study evaluated survival rate and failure mode of severely compromised central incisors without ferrule rehabilitated using resin-based composite (RBC) with or without FGP with different diameters. Methodology A total of 60 decoronated bovine incisors without a ferrule were endodontically treated and prepared for 1.4, 1.6, and 1.8 mm diameter FGPs (Whitepost System DC 0.5, Fit 0.4, and DCE 0.5; FGM). Half of the teeth received FGPs cemented using dual-cure resin cement (Allcem Core; FGM), the other half were filled using only bulk-fill RBC (OPUS Bulk Fill; FGM). The crowns were directly restored with RBC. The roots were embedded in polystyrene resin and the periodontal ligament was simulated with polyether impression material. Fatigue testing was conducted under 5 Hz cyclic loading at 30 degrees to the incisal edge, beginning at 50 N (5,000 cycles) as a warmup. After, the load was increased 100 N every 15,000 cycles until fracture occurred. All specimens were subjected to transillumination, micro-CT analysis, and digital radiography before and after fatigue testing. Fracture mode was classified according to severity and repair potential. Data were analyzed with Kaplan-Meier survival test and post hoc log-rank test (α=0.05) for pairwise comparisons. Results Using FGP significantly increased the number of cycles to failure, irrespective of FGP diameters (p=0.001). The FGP diameters had no statistically significant effect on cycles to failure or failure mode. Conclusion Using FGP without ferrule improved survival rate of structurally severely compromised central incisors compared with rehabilitation without FGP. The diameter of the FGPs had no effect on the survival rate and failure mode.

Abstract This study aimed to identify the best shade level for the growth of Schizolobium parabyba var. amazonicum and Eucalyptus urograndis seedlings to obtain more resilient seedlings with higher quality. We used an entirely randomized design was used, in a 2 x 4-factor scheme, with two species and four levels of shading, comprising 5 repetitions and 6 plants per repetition, totaling 30 plants per treatment. The four shading levels were characterized as follows: T1 (full sun), T2 (50%-shading screen), T3 (plastic), T4 (50%-shading screen plus wool blanket). For the production of Eucalyptus urograndis seedlings, it is recommended an unshaded environment, since one variable showed a significant difference. For the Schizolobium parahyba var. amazonicum species, it is suggested to produce it under shade, where is was achived (50% together with the wool blanket), better results for the most variables.

RESUMO Objetivo: Verificar o efeito do uso do sistema National Early Warning Score (NEWS) na conformidade do intervalo de monitoramento dos sinais vitais com o recomendado em pacientes no pronto-socorro. Método: Estudo quasi-experimental, do tipo antes e depois, realizado em um pronto-socorro com 280 pacientes adultos selecionados por conveniência. O efeito do NEWS na conformidade do intervalo de monitoramento dos sinais vitais com o recomendado pelo sistema foi analisado por regressão linear. Resultados: Na fase Pré-NEWS, foram analisados 143 pacientes (idade média ± desvio-padrão: 54,4 ± 20,5; sexo masculino: 56,6%) e, na fase Pós-NEWS, 137 pacientes (idade média ± desvio-padrão: 55,5 ± 20,8; sexo masculino: 50,4%). Houve conformidade do intervalo de monitoramento dos sinais vitais com o recomendo pelo NEWS em 92,6% dos registros de sinais vitais após adoção desse instrumento. Essa conformidade foi maior na fase Pós-NEWS em 9% (p < 0,001). Conclusão: O uso do sistema NEWS aumentou a conformidade dos intervalos de monitorização dos sinais vitais com o recomendado, porém essa conformidade diminuiu quando o escore NEWS apontou para intervalo menor no monitoramento dos sinais vitais.

ABSTRACT Objective: To verify the effect of using the National Early Warning Score (NEWS) system on the compliance of the vital signs monitoring interval with those recommended for patients in the emergency room. Methods: This is a quasi-experimental, before-and-after study, performed in an emergency room with 280 adult patients selected by convenience. The effect of NEWS on the compliance of the vital signs monitoring interval with those recommended by the system was analyzed by linear regression. Results: In the Pre-NEWS phase, 143 patients were analyzed (mean age ± standard deviation: 54.4 ± 20.5; male: 56.6%) and, in the Post-NEWS phase, 137 patients (mean age ± standard deviation: 55.5 ± 20.8; male: 50.4%). There was compliance of the vital signs monitoring interval with what is recommended by NEWS in 92.6% of vital signs records after adopting this instrument. This compliance was 9% (p < 0.001) higher in the Post-NEWS phase. Conclusion: The use of the NEWS system increased the compliance of the vital signs monitoring intervals with the ones recommended, but this compliance decreased when the NEWS score pointed to a shorter interval in the monitoring of vital signs.

Abstract The objective of this work was to associate the use of biofilms to Lippia sidoides (Lippia) and Morinda citrifolia (Noni) essential oils and their respective major constituents in post-harvest quality components. The evaluations in this study were chromatographic analysis the essential oils, fruit mass reduction effect, total soluble solids, peel color and fruit firmness. Regarding the adjustment and viability of the essential oil concentrations to be used in the treatments, a phytotoxicity test was performed. The main constituent found in Noni essential oil was octanoic acid, while for Lippia essential oil was thymol. The concentration of 3% of Noni and Lippia essential oils was the maximum to reach an acceptable level of phytotoxicity on papaya fruit peel. The paraffin + L. sidoides and paraffin + M. citrifolia treatments achieved the lowest reduction in pulp mass. In relation to total soluble solids, treatments did not show a significant difference. The best result for firmness was found in sunflower oil + noni coating. Sunflower oil + noni and sunflower oil + octanoic acid were the treatments that maintained normal yellow color in fruits for longer time.

Abstract Background Areas simultaneously infested with both glyphosate-resistant sourgrass (Digitaria insularis L.) and fleabane (Conyza spp.) are usual in Brazil. However, there are no effective management strategies to control both species concurrently. Objective The aim was to evaluate the interaction and interval of application of haloxyfop-P-methyl and cloransulam-methyl to effective control sourgrass (from 3- to 4-tillers to flowering stages) and fleabane (12- to 15-cm at the vegetative stage). Methods The experiment was conducted twice in a randomized complete blocks design with four biological replicates. The treatments were composed of sequential applications of haloxyfop-P-methyl (firstly applied) and cloransulam-methyl (secondly applied) and vice-versa. After the first application, the second one was applied in intervals of 3, 6 and 12 days. Haloxyfop-P-methyl and cloransulam-methyl were also applied in sequential (without interval), stand-alone applications of both herbicides and an untreated check. Results All treatments effectively controlled all fleabane plants. Haloxyfop-P-methyl applied ≥ 6 days before cloransulam-methyl controlled 100% of 3- to 4-tillers sourgrass and 60% of flowering sourgrass. Conclusions Therefore, haloxyfop-P-methyl may be applied ≥ 6 days before cloransulam-methyl in a sequential application structure to effectively control fleabane and sourgrass (3- to 4-tillers stage), when present concurrently.

Resumo Este estudo de caso buscou traçar o perfil socioeconômico de participantes de ensaios clínicos em centro de pesquisa brasileiro, analisando suas decisões, motivações e experiências, seu conhecimento sobre riscos, benefícios e cuidados dispensados e o processo de consentimento. Dados de 327 participantes foram coletados, realizando-se entrevistas semiestruturadas com 19 deles. Nas pesquisas executadas no centro estudado houve maior participação de homens, de pessoas com poucos anos de estudo formal e de baixa renda. A maioria é aposentada, não tem assistência privada à saúde e tende a não perceber os efeitos da investigação ou superestimar os benefícios médicos diretos. A busca pelo tratamento médico foi o principal fator que influenciou suas decisões/participação, e a assinatura do termo de consentimento livre e esclarecido não garantiu a expressão da autonomia. Conclui-se que o perfil e o conteúdo dos discursos dos participantes são sensíveis indicadores de vulnerabilidade e desigualdade social.

Abstract This case study aimed to trace the socioeconomic profile of participants in clinical research at a Brazilian research center, analyzing their decisions, motivations, experiences, knowledge of risks, benefits and health care provided, and the consent process. The data of 327 participants were collected, and semi-structured interviews conducted with 19 of them. In the research carried out at the center studied there was a greater participation of men and of people with few years of formal education and low income. Most are retired and have no private health plan, tend not to notice the effects of the investigation, or to overestimate its direct medical benefits. The search for medical treatment was the main factor influencing their decisions/participation, and signing the informed consent form did not guarantee the expression of autonomy. We concluded that the participants’ profile and speeches content are sensitive indicators of vulnerability and social inequality.

Resumo Estudo sobre os participantes de ensaios clínicos na área de oncologia, discutindo o paradoxo entre progresso científico e iniquidade social. Buscou-se conhecer quem são essas pessoas e analisar aspectos envolvidos nas suas decisões, com base em entrevistas e documentos. Houve maior participação feminina. Os participantes tendem a ter poucos anos de estudo formal e baixa renda. A maioria é aposentada e do lar e não tem assistência à saúde privada. Suas decisões giraram em torno da busca pela cura ou melhora, e pela garantia de acesso regular a cuidados integrais de saúde e medicamentos. A assinatura do termo de consentimento livre e esclarecido não garantiu a expressão da autonomia, pois informações essenciais como os objetivos, riscos e cuidados pós-estudo são praticamente desconhecidas. Os participantes da pesquisa tendem a não compreender os objetivos da investigação, ou superestimam os benefícios médicos diretos de sua participação, sem consciência dos riscos envolvidos e do que significa uma pesquisa. Os resultados deveriam incitar ao exercício e ao diálogo mais críticos entre os diferentes atores e instituições envolvidos na área da pesquisa com seres humanos, objetivando promover uma ciência consciente e responsável, que impeça que pessoas sejam colocadas em situação de desigualdade, vulnerabilidade e sofrimento moral.

Abstract This is a study about the participants of clinical trials in the field of oncology that discusses the paradox between scientific advances and social inequality. We sought to get to know these people and to analyze the aspects involved in their decisions based on interviews and documents. Female participation was more expressive. The participants tend to have low schooling and low income. Most of them are retirees and housewives, and do not get assistance from the private health system. Their decisions revolved around the search for cure or recovery, as well as for the assurance of regular access to comprehensive health care and medicines. Signing the free and informed consent form did not guarantee the expression of autonomy, because crucial information, such as the goals, risks and post-study care are virtually unknown. The research participants tend to not understand the goals of the investigation, or they overestimate the direct medical benefits of their participation, and they tend to be unaware of the risks involved and of what does a research mean. The results should stimulate more critical practices and dialogues among the different players and institutions involved in the field of the research with human subjects, with the goal of promoting a science that is conscious and responsible, and that prevents people from being put in situations of inequality, vulnerability and moral suffering.

Resumen Estudio sobre los participantes de ensayos clínicos en el área de oncología, discutiendo la paradoja entre avance científico y desigualdad social. Se buscó conocer quiénes son esas personas y analizar los aspectos involucrados en sus decisiones, con base en entrevistas y documentos. Hubo mayor participación femenina. La tendencia es que los participantes tienen pocos años de estudio formal y bajos ingresos. La mayoría es jubilada y ama de casa, y no tiene asistencia médica privada. Sus decisiones giraron en torno a la búsqueda de la cura o una mejora, y el acceso regular garantizado a la atención médica integral y a los medicamentos. La firma del formulario de consentimiento voluntario e informado no constituyó una expresión de autonomía, ya que información esencial como objetivos, riesgos y cuidados posteriores al estudio es prácticamente desconocida. Los participantes de la investigación tienden a no comprender los objetivos de la investigación, o sobreestiman los beneficios médicos directos de su participación, sin ser conscientes de los riesgos implicados y lo que significa una investigación. Los resultados deberían incitar al ejercicio y al diálogo más críticos entre los diferentes actores e instituciones involucrados en el área de la investigación con seres humanos, a fin de promover un entendimiento consciente y responsable, que impida que las personas sean colocadas en situación de desigualdad, vulnerabilidad y sufrimiento moral.

ABSTRACT Currently, conduct and practices must support health on the best evidence available, subject emphasized in several countries. The purpose of this article is to reflect evidence-based practice in nursing work process. It is theoretical study-reflective, based on scientific literature and critical analysis of authors. Evidence-based practice arises as a movement to use judicious results of scientific research in clinical decision-making. The main challenge for evidence-based care is your implementation, because translating knowledge into action is complex process. That puts us ahead of the challenge the performance of health care professionals in the transformation and adaptation of your clinical practice. It is a fact that the last few decades have marked by an increase in the production of national scientific research to support evidence-based practice; however, the gap between research and practice still prevails. We must educate the professionals, managers, and especially users and patients about the importance of tackling the barriers to the incorporation of this practice, seeking the improvement of work processes in all its dimensions.

RESUMEN Actualmente, prácticas y conductas de salud deben basarse en la mejor evidencia disponible, asunto resaltado en el ámbito académico de diversos países. El objetivo de este artículo es reflexionar acerca de la Práctica Basada en Evidencias en el procedimiento de trabajo de la enfermería. Se trata de un estudio teórico-reflexivo, basado en la literatura científica y el análisis crítico de los autores. La Práctica Basada en Evidencias surge como un movimiento para el uso ponderado de resultados de investigaciones científicas en la toma de decisión clínica. El principal reto para el cuidado basado en evidencias es su aplicación, pues traducir el conocimiento en acción es proceso complejo. Esta reflexión nos pone frente al desafío de la actuación de profesionales de la salud en la transformación y adecuación de su práctica clínica. De hecho, las últimas décadas fueron marcadas por un aumento en la producción de investigaciones científicas nacionales para subvencionar la Práctica Basada en Evidencias, aunque la laguna entre investigación y práctica todavía prevalece. Es necesario concienciar a los profesionales, gestores, y principalmente a usuarios y pacientes sobre la importancia de combatir las barreras para la incorporación de esta práctica, buscando la mejoría de los procedimientos de trabajo en todas sus dimensiones de actuación.

Abstract Objective To analyze the complications deriving from the use and type of peripheral venous catheter in adults. Methods Randomized clinical trial; undertaken at a teaching hospital between 2012 and 2015; 169 adults were included who were hospitalized at clinical and surgical services and needed peripheral venipuncture with an expected dwelling time of more than 96 hours. Through systemized randomization, 90 participants were allocated to the trial group (complete safety catheter) and 79 to the control group (short flexible catheter). Results The general complications rate was 55.62%, with 18.34% of phlebitis, 11.83% infiltration, 11.24% obstruction and 9.47% traction. No significant difference was found between the groups for the occurrence of complications, phlebitis, obstruction and traction. Conclusion The complication rate in peripheral venous catheterization was high but, when compared, without a statistically significant difference, the complete safety catheter showed lower complication rates after the fourth day of survival.

Resumo Objetivo Analisar as complicações decorrentes do uso e tipo de cateter venoso periférico em adultos. Métodos Ensaio clínico randomizado; realizado em um hospital de ensino, no período de 2012 a 2015; incluiu-se 169 adultos internados em unidades clínicas e cirúrgicas que necessitaram de punção venosa periférica e com permanência prevista de mais de 96 horas. A randomização aleatória sistematizada alocou 90 participantes no Grupo Experimental (cateter de segurança completo) e 79 no Grupo Controle (cateter curto flexível). Resultados A taxa geral de complicações foi 55,62%, houve 18,34% de flebite, infiltração 11,83%, obstrução 11,24% e tração 9,47%. Não houve diferença significativa entre os grupos para a ocorrência de complicações, flebite, obstrução e tração. Conclusão A taxa de complicações no cateterismo venoso periférico foi alta, mas quando comparados, sem diferença estatística significativa, o cateter de segurança completo teve taxas menores de complicações após o quarto dia de sobrevida.
