Leisure practice and its relations to cognitive vitality for seniors attending community organizations

The purpose of this study was to explore the relations between certain dimensions of leisure practice and cognitive vitality in seniors and identify which of their sociodemographic and health characteristics (SHC) are related to leisure practice. A cross-sectional analysis of leisure practice, cognitive performance, self-perceived memory and SHC was performed among 294 French-speaking Canadian seniors attending community centres (255 women, average age: 71), by multiple linear regressions and partial correlations controlled for SHC. Outcomes from the project show that the diversity of leisure was related to the Montreal Cognitive Assessment and the California Verbal Learning Test, the frequency of cognitive leisure was associated to the Stroop Test, and the frequency of social leisure showed no significant association. “Paper and pencil games”, “computer use” and “helping a sibling” were related to various cognitive tests. Frequency of leisure (total) was related to gender and education, and diversity of leisure was related to education, age and depression. Study outcomes indicate that diversity of leisure was more related to cognitive vitality than frequency. Future studies should address leisure diversity as a way to promote cognitive vitality among seniors. Moreover, seniors’ characteristics should be considered when seeking to facilitate their participation in leisure activities.Le but de cette étude était d’explorer les relations entre certaines dimensions de la pratique de loisirs et la vitalité cognitive chez des aînés et d’identifier leurs caractéristiques sociodémographiques et de santé (CSS) qui étaient liées à leur pratique de loisirs. Une analyse transversale de la pratique de loisirs, de la performance cognitive, du niveau perçu de la mémoire et des CSS a été réalisée auprès de 294 aînés canadiens parlant français et qui participaient aux activités d’un centre communautaire (255 femmes, âge moyen : 71 ans), par des régressions linéaires multiples et des corrélations partielles contrôlées pour les CSS. Les résultats montrent que la variété des loisirs était liée au Montreal Cognitive Assessment et au California Verbal Learning Test, que la fréquence des loisirs cognitifs était associée au test de Stroop et que la fréquence des loisirs sociaux ne montrait aucune association. Les « jeux papier-crayon », « l’utilisation de l’ordinateur » et « prendre soin d’un proche » étaient reliés à plusieurs tests cognitifs. La fréquence totale des loisirs était liée au sexe et à l’éducation et la variété des loisirs était liée à l’éducation, à l’âge et à la dépression. Les résultats de cette étude montrent que la variété des loisirs était davantage liée à la vitalité comparée à la fréquence des loisirs. De futures études devraient aborder la variété des loisirs comme une manière de promouvoir la vitalité cognitive chez les aînées. De plus, les caractéristiques des aînés devraient être considérées afin de favoriser leur participation aux activités de loisirs dans les centres communautaires

Proceedings of the 3rd Biennial Conference of the Society for Implementation Research Collaboration (SIRC) 2015: advancing efficient methodologies through community partnerships and team science

It is well documented that the majority of adults, children and families in need of evidence-based behavioral health interventionsi do not receive them [1, 2] and that few robust empirically supported methods for implementing evidence-based practices (EBPs) exist. The Society for Implementation Research Collaboration (SIRC) represents a burgeoning effort to advance the innovation and rigor of implementation research and is uniquely focused on bringing together researchers and stakeholders committed to evaluating the implementation of complex evidence-based behavioral health interventions. Through its diverse activities and membership, SIRC aims to foster the promise of implementation research to better serve the behavioral health needs of the population by identifying rigorous, relevant, and efficient strategies that successfully transfer scientific evidence to clinical knowledge for use in real world settings [3]. SIRC began as a National Institute of Mental Health (NIMH)-funded conference series in 2010 (previously titled the “Seattle Implementation Research Conference”; $150,000 USD for 3 conferences in 2011, 2013, and 2015) with the recognition that there were multiple researchers and stakeholdersi working in parallel on innovative implementation science projects in behavioral health, but that formal channels for communicating and collaborating with one another were relatively unavailable. There was a significant need for a forum within which implementation researchers and stakeholders could learn from one another, refine approaches to science and practice, and develop an implementation research agenda using common measures, methods, and research principles to improve both the frequency and quality with which behavioral health treatment implementation is evaluated. SIRC’s membership growth is a testament to this identified need with more than 1000 members from 2011 to the present.ii SIRC’s primary objectives are to: (1) foster communication and collaboration across diverse groups, including implementation researchers, intermediariesi, as well as community stakeholders (SIRC uses the term “EBP champions” for these groups) – and to do so across multiple career levels (e.g., students, early career faculty, established investigators); and (2) enhance and disseminate rigorous measures and methodologies for implementing EBPs and evaluating EBP implementation efforts. These objectives are well aligned with Glasgow and colleagues’ [4] five core tenets deemed critical for advancing implementation science: collaboration, efficiency and speed, rigor and relevance, improved capacity, and cumulative knowledge. SIRC advances these objectives and tenets through in-person conferences, which bring together multidisciplinary implementation researchers and those implementing evidence-based behavioral health interventions in the community to share their work and create professional connections and collaborations

L’entrepreneurship ethnique à Montréal : première esquisse

Cette note de recherche présente une première esquisse de l'étude que nous menons sur l'entrepreneurship ethnique. Elle expose d'abord notre cadre théorique et présente ensuite quelques résultats préliminaires. Nous examinons, dans cette recherche, divers groupes ethniques, tant majoritaires que minoritaires. Pour chacun d'entre eux, nous analyserons l'impact qu'exercent le statut d'immigrant, l'appartenance de sexe, le secteur industriel et le contexte urbain sur l'activité entrepreneur idle. Nous serons ainsi en mesure de mieux cerner et de comprendre, dans une perspective comparative, diverses facettes qui caractérisent ce phénomène.This research note presents a first sketch of a study we are undertaking on ethnic entrepreneur ship. It details first of all our theoretical framework and then presents some preliminary results. For this research, we are studying various ethnic groups, those in the majority as well as the minority. For each of them, we will analyze the impact that immigration status, sex, the industrial sector and urban context play on entrepreneurial activity. We thus hope to be better able to define and understand, in a comparative perspective, various facets which characterize this phenomenon.Esta nota de investigaciôn hace una primera presentación del estudio que estamos realizando sobre las empresas êtnicas. En ella exponemos primero nuestro marco teòrico, y presentamos luego algunos resultados preliminares. En este estudio, examinâmes distintos grupos étnicos, tanto mayoritarios corno minoritarios. Para cada uno de ellos, analizaremos el impacto que tienen sobre la actividad empresarial el estatuto de inmigrante, el sexo, el sector industrial y el contexto urbano. Asi, esperamos poder definir y comprender, en una perspectiva comparativa, distintas facetas que caracterizan este fenòmeno

A Papillary Muscle Repositioning Device for the Elimination of Mitral Regurgitation

Myocardial infarction can induce mitral regurgitation through the displacement of the papillary muscles by 2.5-5mm, leading to pulmonary hypertension, atrial fibrillation, and heart failure. MQP GRG 1601 designed a cantilever papillary muscle repositioning device for the elimination of mitral regurgitation. Insertion occurred through port access surgery, where the muscles would be maneuvered to a position that would allow for proper closure of the mitral valve leaflets. This was tested through simulations, force effect diagrams, and in vitro experiments
