RESUMO
BACKGROUND: The phytochemical content present in blueberries has generated great interest, especially in the nutra-pharmaceutical industry, where it is known as the "super fruit" due to its prevention and treatment of neurodegenerative diseases (cardiovascular diseases, diabetes, and cancer, among others). OBJECTIVES: This study evaluated the functional potential of fresh blueberries and dried blueberries using forced convection by measuring phytochemical content to conclude if this drying technology is convenient for prolonging the product's shelf life. METHODS: For this purpose, antioxidant activity, phenolic content, total anthocyanins, and total flavonoids of 'Biloxi' blueberry cultivars were determined. Fresh and dried blueberries' results were studied. Fruit extracts were analyzed to determine antioxidant activity using 2,2-diphenyl-1-picrylhydrazyl (DPPH) as a free radical, total phenolic content with Folin-Ciocalteu reagent, total anthocyanins by pH differential method, and total flavonoids by Aluminum Chloride method. RESULTS: Results for fresh blueberries yielded ranges of antioxidant activity (90.8-93.9% Free radical scavenging rate), total phenolic content (275 to 645mgGAE/100gFW), total anthocyanins content (28.55 to 43.75mgCy3G/100gFW) and total flavonoids content (159.92 to 335.75mgQE/100gFW). For the forced convection oven process, ranges of antioxidant activity (85.5-92.6% Free radical scavenging rate), total phenolic content (261 to 308mgGAE/100gFW), total anthocyanins content (4.74 to 5.12mgCy3G/100gFW) and total flavonoids content (30.66±0.38mgQE/100gFW) were obtained. CONCLUSIONS: In general, blueberries studied proved to have similar concentrations of functional properties compared to a wide variety of cultivars grown around the globe. Furthermore, higher concentrations of phytochemical content than those reported previously for strawberries, blackberries, and raspberries were evidenced. Although dried blueberries studied proved to have diminished phytochemical content, this functional component content stands out among the fruits market and give nutritional value to end consumers. Drying processes could potentially increase the commerce of blueberries by significantly reducing their perishable nature
CONTEXTO: El contenido fitoquímico presente en los arándanos ha generado gran interés, especialmente en la industria nutra-farmacéutica donde es conocido como una "super fruta" debido a su ayuda en la prevención y tratamiento de enfermedades neurodegenerativas, enfermedades cardiovasculares, diabetes, cáncer, entre otras. OBJETIVOS: Este estudio evaluó el potencial funcional de arándanos frescos y deshidratados por convección forzada mediante la determinación de su contenido fitoquímico con el objetivo de concluir si esta tecnología de secado es conveniente para aumentar la vida útil del producto. MÉTODOS: Para este propósito, se determinó la actividad antioxidante, el contenido fenólico, las antocianinas totales y los flavonoides totales de cultivos de arándanos 'Biloxi' La información recopilada de la literatura fue analizada. Se estudió el contenido en compuestos funcionales en arándanos frescos y deshidratados. Los extractos de fruta fueron analizados para determinar actividad antioxidante por medio de 2,2-Difenil-1-Picrilhidrazilo (DPPH) como radical libre, fenólicos totales con el reactivo Folin-Ciocalteu, antocianinas totales usando el método diferencial de pH y flavonoides totales con el método de Cloruro de Aluminio. RESULTADOS: Para los arándanos frescos se obtuvieron rangos de actividad antioxidante de 90.8-93.9% Tasa de captación de radicales libres, contenido fenólico total de 275-645mgEAG/100gPF, contenido de antocianinas totales de 28.55-43.75mgCy3G/100gPF y contenido total de flavonoides de 159.92-335.75mgEQ/100gPF. Para los arándanos deshidratados por convección forzada, se obtuvieron rangos de actividad antioxidante de 85.5-92.6% Tasa de captación de radicales libres, contenido fenólico total de 261-308mgEAG/100gPF, contenido de antocianinas totales de 4.74-5.12mgCy3G/100gPF y contenido total de flavonoides de 30.24-30.96mgEQ/100gPF. CONCLUSIONES: En general, los arándanos estudiados probaron tener concentraciones similares de propiedades funcionales comparados con una amplia variedad de cultivos alrededor del mundo. Además, fueron evidenciadas concentraciones más altas de contenido fitoquímico comparadas con las reportadas previamente para fresas, moras y frambuesas. Aunque los arándanos secos estudiados demostraron tener menor contenido fitoquímico, la cantidad de estos componentes funcionales destaca dentro del mercado de las frutas y dan valor nutricional a los consumidores. Los procesos de secado pueden potencialmente incrementar el comercio de arándanos derivado de una disminución significativa en su naturaleza perecedera

BACKGROUND: Care and support of children with physical or mental disabilities are accompanied with serious concerns for parents, families, healthcare institutions, schools, and their communities. Recent studies and technological innovations have demonstrated the feasibility of providing therapy and rehabilitation services to children supported by computer games. OBJECTIVE: The aim of this paper is to present HapHop-Physio, an innovative computer game that combines exercise with fun and learning, developed to support cognitive therapies in children. METHODS: Conventional software engineering methods such as the Scrum methodology, a functionality test and a related usability test, were part of the comprehensive methodology adapted to develop HapHop-Physio. RESULTS: The game supports visual and auditory attention therapies, as well as visual and auditory memory activities. The game was developed by a multidisciplinary team, which was based on the Hopscotch® platform provided by Fraunhofer Institute for Digital Media Technology IDMT Institute in Germany, and designed in collaboration with a rehabilitation clinic in Colombia. HapHop-Physio was tested and evaluated to probe its functionality and user satisfaction. CONCLUSION: The results show the development of an easy-to-use and funny game by a multidisciplinary team using state-of-the-art videogame technologies and software methodologies. Children testing the game concluded that they would like to play again while undergoing rehabilitation therapies.
RESUMO
BACKGROUND: Stress-related disorders have become one of the main health problems in many countries and organizations worldwide. They can generate depression and anxiety, and could derive in work absenteeism and reduction in productivity. OBJECTIVE: Design, develop, and evaluate an mHealth App for the prevention of Burnout Syndrome following the recommendations of standard User-Centered Design methodologies. RESULTS: 1) A descriptive cross-sectional study was performed on a sample of 59 faculty members and workers at the University of Cauca, Colombia using the Maslach Burnout Inventory as an instrument for measuring Burnout, accompanied by a demographic and technological questionnaire. 2) Three prototypes of the mHealth App were iteratively developed following the recommendations provided by the ISO Usability Maturity Model and the ISO User-Centered Design model. 3) Usability tests of the system were performed based on the ISO 9126 standard. CONCLUSIONS: The results obtained are considered positive, particularly those regarding user's satisfaction measured using the System Usability Scale.

PROBLEM: Stress-related disorders have become one of the main problems of public health in many countries and of worldwide organizations, and they are expected to become more common in the forthcoming decades. OBJECTIVE: This article aims at providing a systematic review and a descriptive evaluation of the interventions supported by ICT for the prevention and treatment of occupational stress. METHODS: A systematic review of five databases (EBSCO, The Cochrane Library, PubMed, ScienceDirect and IEEEXplorer) was carried out. RESULTS: This article provides a quantitative and qualitative description of 21 studies about occupational stress interventions supported by ICT. The following factors were considered for the analysis: impact of the intervention, design of the study, type of intervention, purpose of the intervention, type of instrument for the measurement of occupational stress, and type of ICT used. CONCLUSIONS: The systematic review demonstrated that interventions supported by ICT for the prevention and treatment of occupational stress are scarce but effective.
