Model projections on the impact of HCV treatment in the prevention of HCV transmission among people who inject drugs in Europe"
Prevention of hepatitis C virus (HCV) transmission among people who inject drugs (PWID) is critical for eliminating HCV in Europe. We estimated the impact of current and scaled-up HCV treatment with and without scaling up opioid substitution therapy (OST) and needle and syringe programmes (NSPs) across Europe over the next 10 years. We collected data on PWID HCV treatment rates, PWID prevalence, HCV prevalence, OST, and NSP coverage from 11 European settings. We parameterised an HCV transmission model to setting-specific data that project chronic HCV prevalence and incidence among PWID. At baseline, chronic HCV prevalence varied from <25% (Slovenia/Czech Republic) to >55% (Finland/Sweden), and <2% (Amsterdam/Hamburg/Norway/Denmark/Sweden) to 5% (Slovenia/Czech Republic) of chronically infected PWID were treated annually. The current treatment rates using new direct-acting antivirals (DAAs) may achieve observable reductions in chronic prevalence (38-63%) in 10 years in Czech Republic, Slovenia, and Amsterdam. Doubling the HCV treatment rates will reduce prevalence in other sites (12-24%; Belgium/Denmark/Hamburg/Norway/Scotland), but is unlikely to reduce prevalence in Sweden and Finland. Scaling-up OST and NSP to 80% coverage with current treatment rates using DAAs could achieve observable reductions in HCV prevalence (18-79%) in all sites. Using DAAs, Slovenia and Amsterdam are projected to reduce incidence to 2 per 100 person years or less in 10 years. Moderate to substantial increases in the current treatment rates are required to achieve the same impact elsewhere, from 1.4 to 3 times (Czech Republic and France), 5-17 times (France, Scotland, Hamburg, Norway, Denmark, Belgium, and Sweden), to 200 times (Finland). Scaling-up OST and NSP coverage to 80% in all sites reduces treatment scale-up needed by 20-80%. The scale-up of HCV treatment and other interventions is needed in most settings to minimise HCV transmission among PWID in Europe. Measuring the amount of HCV in the population of PWID is uncertain. To reduce HCV infection to minimal levels in Europe will require scale-up of both HCV treatment and other interventions that reduce injecting risk (especially OST and provision of sterile injecting equipment
Effects of antiplatelet therapy on stroke risk by brain imaging features of intracerebral haemorrhage and cerebral small vessel diseases: subgroup analyses of the RESTART randomised, open-label trial
Background
Findings from the RESTART trial suggest that starting antiplatelet therapy might reduce the risk of recurrent symptomatic intracerebral haemorrhage compared with avoiding antiplatelet therapy. Brain imaging features of intracerebral haemorrhage and cerebral small vessel diseases (such as cerebral microbleeds) are associated with greater risks of recurrent intracerebral haemorrhage. We did subgroup analyses of the RESTART trial to explore whether these brain imaging features modify the effects of antiplatelet therapy
Biological and clinical insights from genetics of insomnia symptoms
Insomnia is a common disorder linked with adverse long-term medical and psychiatric outcomes. The underlying pathophysiological processes and causal relationships of insomnia with disease are poorly understood. Here we identified 57 loci for self-reported insomnia symptoms in the UK Biobank (n = 453,379) and confirmed their effects on self-reported insomnia symptoms in the HUNT Study (n = 14,923 cases and 47,610 controls), physician-diagnosed insomnia in the Partners Biobank (n = 2,217 cases and 14,240 controls), and accelerometer-derived measures of sleep efficiency and sleep duration in the UK Biobank (n = 83,726). Our results suggest enrichment of genes involved in ubiquitin-mediated proteolysis and of genes expressed in multiple brain regions, skeletal muscle, and adrenal glands. Evidence of shared genetic factors was found between frequent insomnia symptoms and restless legs syndrome, aging, and cardiometabolic, behavioral, psychiatric, and reproductive traits. Evidence was found for a possible causal link between insomnia symptoms and coronary artery disease, depressive symptoms, and subjective well-being
Effects of antiplatelet therapy after stroke due to intracerebral haemorrhage (RESTART): a randomised, open-label trial
Background:
Antiplatelet therapy reduces the risk of major vascular events for people with occlusive vascular disease, although it might increase the risk of intracranial haemorrhage. Patients surviving the commonest subtype of intracranial haemorrhage, intracerebral haemorrhage, are at risk of both haemorrhagic and occlusive vascular events, but whether antiplatelet therapy can be used safely is unclear. We aimed to estimate the relative and absolute effects of antiplatelet therapy on recurrent intracerebral haemorrhage and whether this risk might exceed any reduction of occlusive vascular events.
Methods:
The REstart or STop Antithrombotics Randomised Trial (RESTART) was a prospective, randomised, open-label, blinded endpoint, parallel-group trial at 122 hospitals in the UK. We recruited adults (≥18 years) who were taking antithrombotic (antiplatelet or anticoagulant) therapy for the prevention of occlusive vascular disease when they developed intracerebral haemorrhage, discontinued antithrombotic therapy, and survived for 24 h. Computerised randomisation incorporating minimisation allocated participants (1:1) to start or avoid antiplatelet therapy. We followed participants for the primary outcome (recurrent symptomatic intracerebral haemorrhage) for up to 5 years. We analysed data from all randomised participants using Cox proportional hazards regression, adjusted for minimisation covariates. This trial is registered with ISRCTN (number ISRCTN71907627).
Findings:
Between May 22, 2013, and May 31, 2018, 537 participants were recruited a median of 76 days (IQR 29–146) after intracerebral haemorrhage onset: 268 were assigned to start and 269 (one withdrew) to avoid antiplatelet therapy. Participants were followed for a median of 2·0 years (IQR [1·0– 3·0]; completeness 99·3%). 12 (4%) of 268 participants allocated to antiplatelet therapy had recurrence of intracerebral haemorrhage compared with 23 (9%) of 268 participants allocated to avoid antiplatelet therapy (adjusted hazard ratio 0·51 [95% CI 0·25–1·03]; p=0·060). 18 (7%) participants allocated to antiplatelet therapy experienced major haemorrhagic events compared with 25 (9%) participants allocated to avoid antiplatelet therapy (0·71 [0·39–1·30]; p=0·27), and 39 [15%] participants allocated to antiplatelet therapy had major occlusive vascular events compared with 38 [14%] allocated to avoid antiplatelet therapy (1·02 [0·65–1·60]; p=0·92).
Interpretation:
These results exclude all but a very modest increase in the risk of recurrent intracerebral haemorrhage with antiplatelet therapy for patients on antithrombotic therapy for the prevention of occlusive vascular disease when they developed intracerebral haemorrhage. The risk of recurrent intracerebral haemorrhage is probably too small to exceed the established benefits of antiplatelet therapy for secondary prevention

Le Grand Jeu, entre illusio et lucidité
Lancé par trois bacheliers brillants frais arrivés de Reims, Roger Gilbert-Lecomte, René Daumal et Roger Vailland, le « Grand Jeu » entre sur la scène parisienne avec panache et ferveur en 1928. Noyé dans la nébuleuse des revues d’avant-garde qui naissent et meurent alors dans le sillage du surréalisme d’André Breton, c’est à pas feutrés qu’il en sort, trois ans et trois numéros plus tard, dans le silence de la drogue et des bifurcations. Aventure ambitieuse, exemplaire des générations sponta..
Jeux et enjeux de la polynomie : le cas du poète Roger Gilbert-Lecomte
En 1927, de jeunes et brillants bacheliers créent le groupe du Grand Jeu et lancent sur la place des avant-gardes parisiennes une revue du même nom qui comptera trois numéros, de 1928 à 1930. Parisienne quand elle éclôt, l’aventure a des prémices provinciales : c’est au lycée de Reims que tout a commencé, et Paris n’est que le prolongement étudiant de choses largement engagées dans l’adolescence. Comme cela avait été le cas à Rennes à l’époque d’Alfred Jarry, puis à Nantes autour de Jacques V..
Introduction : Lire, une expérience de relation
International audienceLa didactique de la lecture s'est déplacée, depuis une quinzaine d'années, vers le lecteur, non pas seulement pour mettre en évidence les habiletés ou stratégies que celui-ci peut être amené à développer face aux difficultés d'un texte, mais pour le prendre en compte dans sa qualité de sujet, dont l'expérience, la sensibilité, les pratiques sociales et la culture éducative déterminent des styles et des attitudes de lecture qui varient selon le statut des textes, les supports et la perception qu'il a lui-même des processus de compréhension, d'interprétation et d'appropriation de leurs contenus. C'est donc autour de l'expérience du lecteur et des différentes médiations mises en oeuvre par les enseignants de français langue maternelle et/ou étrangère, que les différentes contributions de ce volume ont été réunies. Linguistes, littéraires et didacticiens proposent ici une réflexion plurielle, faisant dialoguer les disciplines et les approches, théoriques et pratiques, sur l'évolution de la didactique de la lecture et la conception de la littérature, sur les pratiques d'enseignement et les cultures éducatives, sur les spécificités de l'expérience de lecture en langue étrangère ainsi que sur l'évolution des supports, en intégrant, notamment, la relation à l'image. Contributions de : Auréliane Baptiste, Jean-Louis Chiss, Fran- cine Cicurel, Florence Ferran, Emmanuel Fraisse, Anne Godard, Anne-Marie Havard, Vincent Jouve, Dominique Maingueneau, Hélène Merlin-Kajman, Patricia von Münchow, Anne-Claire Rai- mond, Ève-Marie Rollinat-Levasseur, Youmna Tohmé, François Vanoosthuyse et Monica Vlad
