To evaluate the quality of information about health and medication available on Brazilian websites. A descriptive study with a quantitative approach regarding Brazilian websites, conducted from January to March 2011. The search sites were located using two search phrases: "medication information" and "health information." The choice of variables was based on the Internet information quality criteria of the World Health Organization and the International Code of Ethics for health and services sites on the Internet. The dependent variable was whether the site had information about health or medication. The independent variables were access, appearance, organization, honesty, transparency, responsibility and origin. For statistical analysis, the χ2 and Fisher exact tests were applied, with a significance level of 5%. Of the 37 Brazilian sites analyzed, 24 (64.9%) contained health information and 13 (35.1%) contained medication information. Regarding appearance, organization and access criteria, most sites related to health and medication were easily accessible, easy to understand, used objective language, were updated and organized logically and provided accurate and scientifically grounded information. The honesty criterion differed significantly between sites, and the quality of information presented on health and medication websites showed significant differences, suggesting the need for a more systematic organization of these topics on the Internet.

BACKGROUND AND PURPOSE—: Patients with large vessel occlusion strokes (LVOS) may be better served by direct transfer to endovascular capable centers avoiding hazardous delays between primary and comprehensive stroke centers. However, accurate stroke field triage remains challenging. We aimed to develop a simple field scale to identify LVOS. METHODS—: The Field Assessment Stroke Triage for Emergency Destination (FAST-ED) scale was based on items of the National Institutes of Health Stroke Scale (NIHSS) with higher predictive value for LVOS and tested in the Screening Technology and Outcomes Project in Stroke (STOPStroke) cohort, in which patients underwent computed tomographic angiography within the first 24 hours of stroke onset. LVOS were defined by total occlusions involving the intracranial internal carotid artery, middle cerebral artery-M1, middle cerebral artery-2, or basilar arteries. Patients with partial, bihemispheric, and anterior+posterior circulation occlusions were excluded. Receiver operating characteristic curve, sensitivity, specificity, positive predictive value, and negative predictive value of FAST-ED were compared with the NIHSS, Rapid Arterial Occlusion Evaluation (RACE) scale, and Cincinnati Prehospital Stroke Severity (CPSS) scale. RESULTS—: LVO was detected in 240 of the 727 qualifying patients (33%). FAST-ED had comparable accuracy to predict LVO to the NIHSS and higher accuracy than RACE and CPSS (area under the receiver operating characteristic curve: FAST-ED=0.81 as reference; NIHSS=0.80, P=0.28; RACE=0.77, P=0.02; and CPSS=0.75, P=0.002). A FAST-ED ≥4 had sensitivity of 0.60, specificity of 0.89, positive predictive value of 0.72, and negative predictive value of 0.82 versus RACE ≥5 of 0.55, 0.87, 0.68, and 0.79, and CPSS ≥2 of 0.56, 0.85, 0.65, and 0.78, respectively. CONCLUSIONS—: FAST-ED is a simple scale that if successfully validated in the field, it may be used by medical emergency professionals to identify LVOS in the prehospital setting enabling rapid triage of patients. © 2016 American Heart Association, Inc.

Introduction: There is scientific evidence that shows health contributes to the quality of life. These measurements have not been well guided towards the free response of oral health in people's lives. Objective: This study aimed to investigate the impact of tooth loss on the quality of life of elderly people. Material and methods: Qualitative investigation with descriptive features - which used a random sample out of the total edentulous elderly people, who lived in an institution in Fortaleza, Brazil - was carried out. From 250 residents screened, 72 completely edentulous elderly, with ages from 60 to 79 years were selected. A semi-structured questionnaire was used with closed and opened questions in which the last one was used for the free flow of the interviewee's responses. The content was analysed and codified according to Bardin. Results: In total, 84.7% had attended the dentist to have exodontia. Of them, 81.9% reported difficulties after losing their teeth. Physical dimensions, characterised by the difficulties in eating and social dimensions, because of interference in communication with other people were obtained. Conclusion: Tooth loss causes disorder in the individual's quality of life, mainly when it affects their well-being and appearance. © 2011 The Gerodontology Society and John Wiley & Sons A/S.

This paper analyzes the role of religiosity and the impact of social support in the lives of Brazilian migrants in Japan. Despite being in Japan for over two decades, the Brazilians are not integrated into the local society. This social alienation has a negative effect on the health of the migrants, making them prone to mental and physical distress. The lack of language skills prevents the migrants from looking for professional help, and even if they seek for it they cannot express themselves properly. In this context, the migrants found support among their compatriots and religious groups. This essay is based on ethnographic research carried out in Japan between 2003 and 2006 and focuses on the work and activities of the Catholics among the Brazilian migrants. The data collection was based on 15 semi-structured interviews, which were conducted among the members. Besides the religious support, the group offers the migrants a social support space for their daily lives in Japan. Therefore, the group represents a place of socialization and social support for many Brazilians, which helps them to overcome their feelings of vulnerability. The ecclesiastic power, on the other hand, regulates the migrants' behavior through an ethos and a world view legitimized by the group.

Pattern Recognition | Year: 2012

Today data acquisition technologies come up with large datasets with millions of samples for statistical analysis. This creates a tremendous challenge for pattern recognition techniques, which need to be more efficient without losing their effectiveness. We have tried to circumvent the problem by reducing it into the fast computation of an optimum-path forest (OPF) in a graph derived from the training samples. In this forest, each class may be represented by multiple trees rooted at some representative samples. The forest is a classifier that assigns to a new sample the label of its most strongly connected root. The methodology has been successfully used with different graph topologies and learning techniques. In this work, we have focused on one of the supervised approaches, which has offered considerable advantages over Support Vector Machines and Artificial Neural Networks to handle large datasets. We propose (i) a new algorithm that speeds up classification and (ii) a solution to reduce the training set size with negligible effects on the accuracy of classification, therefore further increasing its efficiency. Experimental results show the improvements with respect to our previous approach and advantages over other existing methods, which make the new method a valuable contribution for large dataset analysis. © 2011 Elsevier Ltd.
