Abstract In banana farming, the bagging of bunches with bags impregnated by pyrethroid insecticide is a practice that prevents damage to fruits caused by insect pests. The aim of this study was to monitor the presence and permanence of bifenthrin residue during the maturation of ‘Grande Naine’ banana by gas chromatography coupled to mass spectrometer in the selective ion mode (GC-MS-SIM). Fruits were from bagged and non-bagged bunches and the extraction of bifenthrin residue from peel and pulp was performed with QuEChERS and LSE-LTP (Liquid-Solid Extraction - Low Temperature Partitioning) methods. The maturation stages were characterized as 1; 3 and 7 depending on the fruit peel color. The bifenthrin recovery percentages in banana peel and pulp obtained by QuEChERS and LSE-LTP methods are between 97% and 117%, and therefore, within the criteria of acceptability for residues of agrochemicals according to the Brazilian legislation and vary according to the matrix. The mean bifenthrin concentrations in the peel of fruits from bagged bunches were 0.34 mg kg -1, 0.29 mg kg -1 and 0.10 mg kg -1 at stage 1 (harvest point); 3 and 7, respectively. No bifenthrin residue was detected in fruit pulp at any maturation stage.

RESUMO Objetivo Mensurar a prevalência de úlcera por pressão e a incidência de queda de pacientes em três hospitais de ensino do Município de São Paulo. Método Estudo quantitativo, exploratório-descritivo. Os dados foram coletados no período de agosto de 2012 a julho de 2013, por meio de um formulário e analisados segundo estatística descritiva e inferencial. Resultados A média anual da prevalência geral de úlcera por pressão (UP) foi de 10,1% e a incidência de queda de pacientes foi de 13,8. Conclusão Os pacientes do Hospital 3 foram os mais vulneráveis às úlceras por pressão e à queda, devido, provavelmente, à agressividade da doença e aos tratamentos complexos a que são submetidos. A aplicação desses indicadores vem possibilitando o benchmarking e a revisão dos protocolos institucionais, tanto assistenciais como gerenciais.

ABSTRACT Objective To measure the prevalence of pressure ulcers and the incidence of patient falls in three teaching hospitals in the city of São Paulo. Method Quantitative, exploratory and descriptive study. Data were collected from August 2012 to July 2013 using a form. They were analyzed according to descriptive and inferential statistics. Results The annual mean of pressure ulcers overall prevalence (PU) was of 10.1%, and the incidence of patient falls was of 13.8%. Conclusion Patients of Hospital 3 were the most vulnerable to pressure ulcers and falls, probably due to the aggressiveness of the disease and the complex treatments these patients were undergoing. Implementation of such indicators has enabled benchmarking and review of both assistance and management institutional protocols.

RESUMEN Objetivo Mensurar la prevalencia de úlcera por presión y la incidencia de caídas de pacientes en tres hospitales de enseñanza en São Paulo. Método Un estudio cuantitativo, exploratorio y descriptivo. Los datos fueron recogidos a partir de agosto 2012-julio 2013, a través de un formulario y analizados mediante estadística descriptiva e inferencial. Resultados el promedio anual de la prevalencia general de úlcera por presión (UP) fue 10,1% y la incidencia de caídas de los pacientes fue de 13,8. Conclusión Los pacientes del Hospital 3 fueron más vulnerables a las úlceras por presión y caída, probablemente debido a la agresividad de la enfermedad y los tratamientos complejos a que son sometidos. La aplicación de estos indicadores ha permitido el benchmarking y la revisión de los protocolos institucionales, tanto de asistencia y de gestión.

The plants used in traditional medicine have been considered an important source of molecules with pharmacological activity, including antitumor. The aim of this study was to present a pharmacological description and the phytochemical components related to antitumor activity of thirty plants commonly cited in Brazil to treat tumors as well as offering an overview of approaches that are necessary for the development of herbal medicines from these resources. In the search for studies with these plants, five database were used (SciELO, Scirus, Scopus, Biological Abstracts and Web of Science), with the following keywords: tumor AND Species AND cancer. We consider all the scientific synonyms of species available in the Tropicos® database (http://www.tropicos.org/). We surveyed papers from the period between 1980 and 2008. Twnety one species (70%) have at least one evaluation of a class of molecule or metabolite isolated against a pharmacological model. Most species (60%) has in vivo studies. Of the thirty plant species, two stood out for having pharmacological studies in vitro, in vivo and clinical with positive results: Chelidonium majus L., Papaveraceae, and Aloe arborescens Mill., Xanthorrhoeaceae. Although there is generally a good activity of species presented here, there is a need for further studies in order to evaluate the possibility of developing some byproduct.
