RESUMEN

Analysis of biomedical images requires computational expertize that are uncommon among biomedical scientists. Deep learning approaches for image analysis provide an opportunity to develop user-friendly tools for exploratory data analysis. Here, we use the visual programming toolbox Orange ( http://orange.biolab.si ) to simplify image analysis by integrating deep-learning embedding, machine learning procedures, and data visualization. Orange supports the construction of data analysis workflows by assembling components for data preprocessing, visualization, and modeling. We equipped Orange with components that use pre-trained deep convolutional networks to profile images with vectors of features. These vectors are used in image clustering and classification in a framework that enables mining of image sets for both novel and experienced users. We demonstrate the utility of the tool in image analysis of progenitor cells in mouse bone healing, identification of developmental competence in mouse oocytes, subcellular protein localization in yeast, and developmental morphology of social amoebae.

RESUMEN

BACKGROUND: The use of targeted therapies has recently increased. Pharmacogenetic tests are a useful tool to guide patient treatment and to test a response before administering medicines. Pharmacogenetic tests can predict potential drug resistance and may be used for determining genotype-based drug dosage. However, their cost-effectiveness as a diagnostic tool is often debatable. In Germany, 47 active ingredients are currently approved. A prior predictive test is required for 39 of these and is recommended for eight. The objective of this study was to review the cost-effectiveness (CE) of pharmacogenetic test-guided drug therapy and compare the application of drugs with and without prior genetic testing. METHODS: A systematic literature review was conducted to identify the CE and cost-utility of genetic tests. Studies from January 2000 until November 2015 were searched in 16 databases including Medline, Embase, and Cochrane. A quality assessment of the full-text publications was performed using the validated Quality of Health Economic Studies (QHES) instrument. RESULTS: In the majority of the included studies, the pharmacogenetic test-guided therapy represents a cost-effective/cost-saving treatment option. Only seven studies lacked a clear statement of CE or cost-savings, because of uncertainty, restriction to specific patient populations, or assumptions for comparative therapy. Moreover, the high quality of the available evidence was evaluated. CONCLUSION: Pharmacogenetic testing constitutes an opportunity to improve the CE of pharmacotherapy. The CE of targeted therapies depends on various factors including costs, prevalence of biomarkers, and test sensitivity and specificity. To guarantee the CE comparability of stratified drug therapies, national and international standards for evaluation studies should be defined.

RESUMEN

To meet and work with teenagers may be a challenge for caregivers as adolescence is a period when youths try to establish autonomy. Although asthma is an increasing problem worldwide, few studies have addressed professional caregivers' motives and actions. Therefore, the aim of this study was to describe professional caregivers' strategies in their work with teenagers with asthma. Grounded theory, inspired by Glaser, was used to uncover the phenomenon. The informants were seven professional caregivers who worked at an eight-day asthma camp for teenagers in Sweden. Participant observations and interviews were used, and the first author collected the data and participated in the activities. Findings show that professional caregivers' core concern is to assist teenagers with asthma to take command. This core concern gives rise to five strategies: showing respect, being at hand, promoting own responsibility, promoting to exceed boundaries and promoting reflections. In professional caregivers' attempt to assist teenagers to take command some differences are seen in the way they support boys and girls. One conclusion drawn from our study is that the provisional theory of 'Assisting teenagers with asthma to take command' is not only suitable for professional caregivers working at asthma camps; it may, in some degree, also be used as a source of inspiration for professional caregivers in other settings.

RESUMEN

Adolescence is a period when teens normally revolt against being dependent. For teens with asthma this period may be even more difficult to deal with, as they also have to deal with their illness. Since few studies describe this phenomenon, the aim of this study was to provide a theoretical understanding of how teens with asthma manage their everyday life in relation to their disease. A grounded theory research design, according to Glaser, was used to uncover the phenomenon. The study was undertaken at a camp for teenagers with asthma during the summer of 2003. Twelve girls and 11 boys with moderate to severe asthma participated in the study. Participant observations and interviews were used, and the first author collected the data and participated in the activities. The findings reveal a theoretical model which shows that teens' core concern is not to let the disease get the upper hand over life. To manage this core concern the teens were found to use three strategies: keeping a distance to the disease, challenging the disease and taking the disease into consideration. Boys mainly kept a distance to the disease while girls mainly kept the disease into consideration. Challenging the disease seemed to be a strategy used by both girls and boys. The teens' strategies were not studied close to their everyday life, but a conclusion drawn from our study was that the provisional theory in many respects can be transferred to their everyday life, even though further research is needed to develop this provisional theory in other settings.
