Is systematic training in opioid overdose prevention effective?

The objectives were to analyze the knowledge about overdose prevention, the use of naloxone, and the number of fatal overdoses after the implementation of Systematic Training in Overdose Prevention (STOOP) program. We conducted a quasi-experimental study, and held face-to-face interviews before (n = 725) and after (n = 722) implementation of systematic training in two different samples of people who injected opioids attending harm reduction centers. We asked participants to list the main causes of overdose and the main actions that should be taken when witnessing an overdose. We created two dependent variables, the number of (a) correct and (b) incorrect answers. The main independent variable was Study Group: Intervention Group (IG), Comparison Group (CG), Pre-Intervention Group With Sporadic Training in Overdose Prevention (PREIGS), or Pre-Intervention Group Without Training in Overdose Prevention (PREIGW). The relationship between the dependent and independent variables was assessed using a multivariate Poisson regression analysis. Finally, we conducted an interrupted time series analysis of monthly fatal overdoses before and after the implementation of systematic program during the period 2006-2015. Knowledge of overdose prevention increased after implementing systematic training program. Compared to the PREIGW, the IG gave more correct answers (IRR = 1.40;95%CI:1.33-1.47), and fewer incorrect answers (IRR = 0.33;95%CI:0.25-0.44). Forty percent of people who injected opioids who received a naloxone kit had used the kit in response to an overdose they witnessed. These courses increase knowledge of overdose prevention in people who use opioids, give them the necessary skills to use naloxone, and slightly diminish the number of fatal opioid overdoses in the city of Barcelon

A crustal deformation study of the Charlevoix seismic zone in Quebec

La présente recherche porte sur l’utilisation de données de nivellement géométrique de premier ordre et de données GPS de haute précision pour quantifier les déformations locales causées principalement par le rebond postglaciaire dans la zone sismique de Charlevoix, la région de l’Est du Canada avec l’activité sismique la plus élevée. Pour le nivellement, une partie du réseau canadien de premier ordre, mesuré entre 1909 et 1991, est analysée pour des lignes de nivellement mesurées plus d’une fois. Pour le GPS, un réseau de points géodésiques de premier ordre le long du fleuve Saint-Laurent a été remesuré par GPS en 1991 et en 2005. Le changement des coordonnées de ces points géodésiques permet de déterminer les vitesses horizontales et verticales et d’en tirer de l’information sur la déformation de la croûte terrestre dans cette région. Les résultats obtenus sont en accord avec les résultats de précédents levés GPS sur les piliers du Canadian Base Network (CBN) dans l’Est du Canada ainsi qu’avec les modèles géophysiques de rebond postglaciaire.The present research concerns the use of first order spirit levelling and high precision GPS measurements to quantify the local deformations caused mainly by postglacial rebound in the Charlevoix seismic zone, the region with the highest concentrated seismic activity in eastern Canada. For the levelling, part of the Canadian first order network, measured from 1909 to 1991, is analyzed for repeating levelling lines. For GPS, a part of a first order geodetic network along the Saint Lawrence was surveyed by GPS in 1991 and 2005. The coordinate changes of these geodetic points allows for the determination of horizontal and vertical velocities leading to information on the crustal deformation of this region. The results obtained agree quite well with previous GPS surveys conducted on Canadian Base Network (CBN) pillars in eastern Canada and also with geophysical postglacial rebound (PGR) models
