Cadre conceptuel du jeu préjudiciable: Une collaboration internationale, troisième édition
- 2018
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Si le jeu est souvent considéré comme un divertissement ou un loisir, pour certaines personnes, qu’il s’agisse de familles ou d’individus, voire de la société en général, il peut avoir des répercussions graves. Depuis des décennies, les effets préjudiciables du jeu font l’objet d’études visant à comprendre les distinctions entre la pratique du jeu et le parcours de vie des problèmes liés au jeu. Le présent ouvrage élabore un cadre conceptuel complet et pertinent au niveau international du « jeu préjudiciable » qui identifie les préjudices au-delà d’une vue basée sur les symptômes et aborde une série de facteurs liés aux risques pour la population, de même qu’aux effets sur la communauté et la société. Les facteurs répertoriés dans le cadre représentent des éléments majeurs liés au jeu et sont tantôt spécifiques (environnement de jeu, exposition, types et ressources), tantôt généraux (culturels, sociétaux, psychologiques et biologiques). Le Cadre a été créé par une équipe internationale de spécialistes interdisciplinaires dans le but de faciliter la compréhension du jeu préjudiciable. Il reflète l’état des connaissances liées aux facteurs d’influence du jeu préjudiciable et a pour but secondaire de servir de guide au développement de programmes de recherche futurs et à l’éducation des personnes chargées de prendre des décisions en matière de jeu préjudiciable. Situé à Guelph, en Ontario (Canada), l’organisme Gambling Research Exchange Ontario ou GREO, anciennement Ontario Problem Gambling Research Centre (OPGRC) a facilité l’élaboration du présent Cadre conceptuel sur le jeu préjudiciable et demeurera responsable d’assurer la mise à jour de celui-ci.

Conceptual framework of harmful gambling: An international collaboration, Third Edition
- 2018
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Although it is seen by many as a form of leisure and recreation, gambling can have serious repercussions for individuals, families, and society as a whole. The harmful effects of gambling have been studied for decades in an attempt to understand individual differences in gambling engagement and the life-course of gambling-related problems. In this publication, we present a comprehensive, internationally relevant conceptual framework of “harmful gambling” that moves beyond a symptoms-based view of harm and addresses a broad set of factors related to population risk, community, and societal effects. Factors included in the framework represent major topics relating to gambling that range from specific (gambling environment, exposure, types, and resources) to general (cultural, social, psychological, and biological). The framework has been created by international, interdisciplinary experts in order to facilitate an understanding of harmful gambling. It reflects the state of knowledge related to factors influencing harmful gambling, and serves a secondary purpose as a guide for the development of future research programs and to educate policy makers on issues related to harmful gambling. Gambling Research Exchange Ontario (GREO) (formerly the Ontario Problem Gambling Research Centre (OPGRC) located in Guelph, Ontario, Canada) has facilitated the development of the Conceptual Framework of Harmful Gambling and retains responsibility for keeping it up-to-date.

- Proximity ligation assay (PLA) is a recently developed strategy for protein analysis in which antibody-based detection of a target protein via a DNA ligation reaction of oligonucleotides linked to the antibodies results in the formation of an amplifiable DNA strand suitable for analysis. Here we describe a faster and more cost-effective strategy to construct the antibody-based proximity ligation probes used in PLA that is based on the noncovalent interaction of biotinylated oligonucleotides with streptavidin followed by the interaction of this complex with biotinylated antibodies.

- Background and aims: The Conceptual Framework of Harmful Gambling moves beyond a symptoms-based view of harm and addresses a broad set of factors related to the risks and effects of gambling harmfully at the individual, family, and community levels. Coauthored by international research experts and informed by multiple stakeholders, Gambling Research Exchange (GREO) facilitated the framework development in 2013 and retains responsibility for regular updates and mobilization. This review article presents information about the revised version of the Conceptual Framework of Harmful Gambling completed in late 2018. Methods: We describe eight interrelated factors depicted in the framework that represent major themes in gambling ranging from the specific (gambling environment, exposure, gambling types, and treatment resources) to the general (cultural, social, psychological, and biological influences). After outlining the framework development and collaborative process, we highlight new topics for the recent update that reflect changes in the gambling landscape and prominent discourses in the scientific community. Some of these topics include social and economic impacts of gambling, and a new model of understanding gambling related harm. Discussion and conclusions: We address the relevance of the CFHG to the gambling and behavioral addictions research community. Harm-based frameworks have been undertaken in other areas of addiction that can both inform and be informed by a model dedicated to harmful gambling. Further, the framework brings a multi-disciplinary perspective to bear on antecedents and factors that co-occur with harmful gambling.

- The detection of weakly expressed proteins and protein complexes in biological samples represents a fundamental challenge. We have developed a new proximity-ligation strategy named 3PLA that uses three recognition events for the highly specific and sensitive detection of as little as a hundred molecules of the vascular endothelial growth factor (VEGF), the biomarkers troponin I, and prostate-specific antigen (PSA) alone or in complex with an inhibitor--demonstrating the versatility of 3PLA.

- Neutralizing antibodies (NAb) able to react to heterologous viruses are generated during natural HIV-1 infection in some individuals. Further knowledge is required in order to understand the factors contributing to induction of cross-reactive NAb responses. Here a well-established model of experimental pathogenic infection in cynomolgus macaques, which reproduces long-lasting HIV-1 infection, was used to study the NAb response as well as the viral evolution of the highly neutralization-resistant SIVmac239. Twelve animals were infected intravenously with SIVmac239. Antiretroviral therapy (ART) was initiated ten days post-inoculation and administered daily for four months. Viral load, CD4(+) T-cell counts, total IgG levels, and breadth as well as strength of NAb in plasma were compared simultaneously over 14 months. In addition, envs from plasma samples were sequenced at three time points in all animals in order to assess viral evolution. We report here that seven of the 12 animals controlled viremia to below 10(4) copies/ml of plasma after discontinuation of ART and that this control was associated with a low level of evolutionary divergence. Macaques that controlled viral load developed broader NAb responses early on. Furthermore, escape mutations, such as V67M and R751G, were identified in virus sequenced from all animals with uncontrolled viremia. Bayesian estimation of ancestral population genetic diversity (PGD) showed an increase in this value in non-controlling or transient-controlling animals during the first 5.5 months of infection, in contrast to virus-controlling animals. Similarly, non- or transient controllers displayed more positively-selected amino-acid substitutions. An early increase in PGD, resulting in the generation of positively-selected amino-acid substitutions, greater divergence and relative high viral load after ART withdrawal, may have contributed to the generation of potent NAb in several animals after SIVmac239 infection. However, early broad NAb responses correlated with relatively preserved CD4(+) T-cell numbers, low viral load and limited viral divergence.
