Suivi citoyen des indicateurs des alĂ©as dâĂ©rosion cĂŽtiĂšre et de submersion marine : crĂ©ation de lâapplication smartphone et tablette CoastAppli et expĂ©rimentation Ă GuissĂ©ny (FinistĂšre)
International audienceLes alĂ©as cĂŽtiers (Ă©rosion, submersion, migration dunaire) et les dynamiques cĂŽtiĂšres sont souvent mĂ©connus par le grand public. Or, dans un contexte de changement climatique et dâĂ©volution de la lĂ©gislation (loi « Climat et rĂ©silience » en 2021) sur la gestion des alĂ©as et des risques cĂŽtiers (risque(s) combinant alĂ©a(s) et enjeu(x)), le suivi de lâĂ©volution du littoral au travers dâindicateurs des alĂ©as cĂŽtiers (position du trait de cĂŽte, niveau de la plage, niveau dâeau sur un repĂšre lors dâune submersion, etc.) devrait ĂȘtre lâaffaire de tous. JusquâĂ prĂ©sent, aucune application citoyenne pour smartphone ou tablette ne permettait de suivre conjointement les indicateurs des alĂ©as cĂŽtiers dâĂ©rosion et de submersion, alors que ces deux alĂ©as sont souvent liĂ©s. Pour y remĂ©dier, dans le cadre dâun projet de recherche et de formation (2019-2022) regroupant des Ă©tudiants en gĂ©ographie, en biologie et en informatique, nous avons crĂ©Ă© lâapplication Android CoastAppli. CoastAppli, qui vise un public large (habitants, touristes, scolaires, gestionnaires du littoral, etc.) et a Ă©tĂ© expĂ©rimentĂ©e Ă GuissĂ©ny (FinistĂšre) entre janvier et octobre 2022 auprĂšs de 86 personnes, permet de rĂ©aliser un suivi citoyen des indicateurs dâalĂ©as cĂŽtiers. GrĂące Ă lâimplication des utilisateurs sur les quatre sites de cette commune, les rĂ©sultats soulignent la fiabilitĂ© des donnĂ©es quantitatives (jusquâĂ une erreur globale de ± 4 cm) et/ou qualitatives, ainsi que la haute frĂ©quence dâacquisition (mensuelle). Par ailleurs, cela semble un bon moyen pour comprendre, discuter et rĂ©flĂ©chir entre acteurs du territoire aux dĂ©fis de gestion du littoral dâaujourdâhui et de demain

Increased Tpeak-Tend interval is highly and independently related to arrhythmic events in Brugada syndrome
International audienceRisk stratification in Brugada syndrome (BS) remains controversial. The time interval between the peak and the end of the T wave (Tpe interval), a marker of transmural dispersion of repolarization, has been linked to malignant ventricular arrhythmias in various settings but leads to discordant results in BS
Can CoastAppli (a citizen science smartphone app) improve monitoring and understanding of coastal hazards to support coastal management?
International audienceCoastal erosion and flooding remain unknown hazards and elected officials and coastal managers may have difficulty discussing these phenomena with the general public. However, a better knowledge of the evolution of these hazards, through citizen science, can help raise awareness of coastal dynamics among the general public and thus meet the current and future challenges of coastal management. During the OSIRISC project (2016-2020), funded by the Fondation de France, coastal managers wanted to set up a smartphone app to save time during their field surveys, while allowing citizens to perform some measurements. How to create a citizen science app on coastal hazards that is reliable and intelligible and that guarantees the sustainable support of participants (professionals and non professionals)? Within the framework of the observatory of coastal risks in Brittany (OSIRISC), protocols for measuring hazards 1) with common tools (benchmarks such as the size of one's finger, qualitative data with photographs) or cheap tools (tape measure, laser distance meter...), 2) applicable to all types of coasts (beach, cliffâŠ) have been co-designed with the managers and integrated into the android app called CoastAppli. Co-funded by EUR ISblue (the interdisciplinary graduate school for the blue planet), Sea-Eu and Interreg AGEO projects, CoastAppli is currently being tested for 6 months (until April 2022) in the municipality of GuissĂ©ny (Brittany, France) by grade school students, coastal managers and citizens. The feedback from this test will allow us to know: i) the reliability of the measurements; ii) whether the app meets the expectations of the coastal managers by saving time for data collection in the field; iii) the app ability to be understood and educative; iv) the sustainability of the commitment of the citizens. These results are essential to validate the application before a future deployment that is intended in Brittany, then in France and beyond

Relation of outcomes to ABC (Atrial Fibrillation Better Care) pathway adherent care in European patients with atrial fibrillation: an analysis from the ESC-EHRA EORP Atrial Fibrillation General Long-Term (AFGen LT) Registry
International audienceAbstract Aims There has been an increasing focus on integrated, multidisciplinary, and holistic care in the treatment of atrial fibrillation (AF). The âAtrial Fibrillation Better Careâ (ABC) pathway has been proposed to streamline integrated care in AF. We evaluated the impact on outcomes of an ABC adherent management in a contemporary real-life European-wide AF cohort. Methods and results Patients enrolled in the ESC-EHRA EURObservational Research Programme in AF General Long-Term Registry with baseline data to evaluate ABC criteria and available follow-up data were considered for this analysis. Among the original 11â096 AF patients enrolled, 6646 (59.9%) were included in this analysis, of which 1996 (30.0%) managed as ABC adherent. Patients adherent to ABC care had lower CHA2DS2-VASc and HAS-BLED scores (mean ± SD, 2.68â±â1.57 vs. 3.07â±â1.90 and 1.26â±â0.93 vs. 1.58â±â1.12, respectively; Pâ<â0.001). At 1-year follow-up, patients managed adherent to ABC pathway compared to non-adherent ones had a lower rate of any thromboembolic event (TE)/acute coronary syndrome (ACS)/cardiovascular (CV) death (3.8% vs. 7.6%), CV death (1.9% vs. 4.8%), and all-cause death (3.0% vs. 6.4%) (all Pâ<â0.0001). On Cox multivariable regression analysis, ABC adherent care showed an association with a lower risk of any TE/ACS/CV death [hazard ratio (HR): 0.59, 95% confidence interval (CI): 0.44â0.79], CV death (HR: 0.52, 95% CI: 0.35â0.78), and all-cause death (HR: 0.57, 95% CI: 0.43â0.78). Conclusion In a large contemporary cohort of European AF patients, a clinical management adherent to ABC pathway for integrated care is associated with a significant lower risk for cardiovascular events, CV death, and all-cause death
Impact of partial steps and momentum advection schemes in a global ocean circulation model at eddy-permitting resolution
Series of sensitivity tests were performed with a z-coordinate, global eddy-permitting (1/4Âș) ocean/sea-ice model (the ORCA-R025 model configuration developed for the DRAKKAR project) to carefully evaluate the impact of recent state-of-the-art numerical schemes on model solutions. The combination of an energy-enstrophy conserving (EEN) scheme for momentum advection with a partial step (PS) representation of the bottom topography yields significant improvements in the mean circulation. Well known biases in the representation of western boundary currents, such as in the Atlantic the detachment of the Gulf Stream, the path of the North Atlantic Current, the location of the Confluence, and the strength of the Zapiola Eddy in the south Atlantic, are partly corrected. Similar improvements are found in the Pacific, Indian, and Southern Oceans, and characteristics of the mean flow are generally much closer to observations. Comparisons with other state-of-the-art models show that the ORCA-R025 configuration generally performs better at similar resolution. In addition, the model solution is often comparable to solutions obtained at 1/6 or 1/10Âș resolution in some aspects concerning mean flow patterns and distribution of eddy kinetic energy. Although the reasons for these improvements are not analyzed in detail in this paper, evidence is shown that the combination of EEN with PS reduces numerical noise near the bottom, which is likely to affect current-topography interactions in a systematic way. We conclude that significant corrections of the mean biases presently seen in general circulation model solutions at eddy-permitting resolution can still be expected from the development of numerical methods, which represent an alternative to increasing resolution
