Modern Earth Observation optical satellite systems, such as Airbus’s Pleiades Neo (PNeo) push the boundaries of high spatial resolution by providing commercial imagery products with up to 30cm ground sampling distance (GSD). To further enhance the quality of the images, the in-space imaging system is usually complemented by on-ground image restoration processing, such as deconvolution and denoising (Latry et al., 2012). Recent advances leverage Convolutional Neural Networks (CNNs) to improve the image restoration quality (K. Zhang et al., 2021a).Single Image Super-Resolution (SISR), or Zoom, the process of obtaining a higher resolution (HR) image from a lower resolved (LR) source, has recently gained traction for both medium resolution sensors such as Sentinel 2 (Lanaras et al., 2018) and high resolution such as Pléiades and GeoEye-1 (Zhu et al., 2020). This process further enhances the resolution of the image to improve downstream applications such as mapping (L. Zhang et al., 2021) and small objects recognition (Shermeyer and Van Etten, 2019). While SISR for remote sensing has been successfully tackled using CNNs (Rohith and Kumar, 2021) the main challenge for reaching acceptable image quality performance lies in the generation of realistic LR/HR training pairs (K. Zhang et al., 2021b). In this paper, we propose:a dedicated simulation chain leveraging extremely-high-resolution (EHR) aerial imagery to generate realistic 30cm Pléiades Neo images and their corresponding fully restored HR equivalent at 15cm GSDA residual-based CNN architecture which we train to jointly restore and zoom the images All contributions are assessed on real PNEO images.We deployed the trained models in a production context, to enhance the full Pléiades Neo products – with a swath of 47k pixels – in an efficient and scalable manner.

International audience; Objectives : The co-occurrence of multiple medical or psychosocial conditions (geriatric syndromes (GS) and age-related diseases) is a growing concern in older people. Given the diversity of these conditions and their complex interactions, our aim was to determine whether they could be structured into synthetic dimensions in order to facilitate the management of multimorbidity.Design : The underlying structure of 10 GSs and 8 age-related diseases was identified using a multiple correspondence analysis (MCA), and confronted to subjective and objective health outcomes.Setting : Community residents from Bordeaux City (France) older than 75 years in 2010Participants : 630 adults aged 75+ years who lived in Bordeaux and participated in the 10-year follow-up of the Three-City study.Measurements : GSs included physical frailty, cognitive impairment and dementia, dependency, depressive symptoms, polymedication, thinness, falls, sensory deficit, social isolation, incontinence. Age-related diseases were cancer, cardiac diseases, peripheral vascular diseases, diabetes, hypertension, pulmonary diseases, osteoporosis, other chronic diseases. Association of the MCA-derived independent dimensions was assessed with 10-year visit subjective health and well-being, and with incident death and entry into institution during the remaining cohort follow-up.Results : Most of the participants (82%) had at least two age-related syndromes or diseases. The MCA structured the 18 conditions into three major dimensions: Degradation (D) driven by GS, Vascular (V), and Psychosocial (P) representing 68.7%, 7.4%, and 5.7% of the total variance, respectively. Dimension D was a strong predictor of future death and institutionalization. Dimensions D and P were strongly associated with current well-being.Conclusions : This work confirmed that multimorbidity is very common among older adults, and demonstrated the essential role of GS as manifestations of aging, even more than age-related diseases.

Researchers often use metabolic measurements in the field over narrow time periods to estimate an organism’s metabolism over large time scales. Here, we measured in situ respiration, calcification and excretion rates of the tropical gastropod Tectus niloticus L. through benthic chamber experiments. Our samples spanned a 21 h time frame and were taken during both the warm and cool seasons. We assessed diel and seasonal variability in metabolic rates, as well as the effect of individual size and the contribution of shell epi- and endobionts. Our results show that metabolic rates vary through time at both diel and seasonal scales, as measured fluxes for respiration and calcification were significantly higher at night during the warm season. This nocturnal pattern was not significant in the cool season. Size effects were significant with higher respiration and calcification rates for small individuals regardless of the season, although the difference tended to be more pronounced in the warm season. We also found that shell epi- and endobionts made an important contribution to respiration, as 40 and up to 100% of total measured fluxes for night and day, respectively, could be attributed to the shell community. More importantly, the direction of the measured flux was occasionally opposite that of the individual trochus, highlighting that the contribution of shell epi- and endobionts must be accounted for in order to achieve an accurate understanding of individual metabolism. Lastly, depending on the time of day and season when measurements are taken, ignoring diel or seasonal variations in metabolic rates could result in important under- or overestimation of the contributions of gastropods to carbon and calcium carbonate fluxes in coastal ecosystems.

Persisting adaptive humoral immunity relies on two key cell types: memory B lymphocytes and long-lived plasma cells. Independently from the specific Ig class they produce, those cells can on one side maintain immunity but on the other side account for dysimmune conditions or hypersensitivity. Stringent control is thus required for both their generation and their survival. Among Ig classes, IgE carries the most powerful pro-inflammatory properties, even at minimal concentration. IgE responses and memory, although protecting against parasites and certain venoms, can inversely mediate devastating effects. The long-term memory of anaphylactic responses against allergens thus stands as the black side of IgE responses, accounting for chronic conditions punctuated with dramatic acute adverse events, some eventually lethal. To manage both their value and their danger, the immune system has evolved with multiple and drastic safeguards around IgE responses, notably ensuring a “B-cell self control” which could now be exploited and reinforced by new specific therapeutic strategies., La persistance de l’immunité humorale adaptative repose particulièrement sur 2 acteurs clés : les lymphocytes B mémoires et les plasmocytes à longue durée de vie. Indépendamment de la classe d’immunoglobuline produite, ces cellules peuvent maintenir tant la protection contre des pathogènes que des manifestations d’hypersensibilité ou d’immunopathologie. Elles requièrent donc une régulation stricte de leur génération comme de leur survie. Parmi toutes les classes d’immunoglobuline produites, l’IgE constitue l’anticorps aux propriétés les plus puissantes, pouvant déclencher des réactions inflammatoires majeures même à doses infimes. Les réponses et la mémoire de classe IgE, au rôle protecteur contre les parasites et certains venins ou toxines, sont conservées par l’évolution chez la quasi-totalité des mammifères. Cependant, les réponses anaphylactiques aux venins peuvent à l’inverse être dramatiques et la mémoire à long terme des sensibilisations et des réactions anaphylactiques contre les allergènes constitue le côté obscur des IgE, responsable de pathologies chroniques ponctuées d’évènements aigus parfois fatals. Face à leur utilité mêlée de dangerosité, l’évolution du système immunitaire a entouré les réponses IgE des cellules B de multiples et stricts garde-fous, un self-control naturel en renfort duquel s’ouvrent aujourd’hui de nouvelles voies thérapeutiques.

International audience; Mangrove forests are highly productive coastal ecosystems that significantly influence global carbon cycling. This study characterized the sources of dissolved organic carbon (DOC), particulate organic carbon (POC) and dissolved inorganic carbon (DIC) and the processes affecting their distributions in a mangrove-influenced estuary located in French Guiana (FG), a region representative of these dynamic systems down drift of the Amazon River. Four sampling cruises were carried out between 2013 and 2015 in surface waters of the estuary during dry and wet seasons. Stable isotopes (δ13DOC, δ13POC, δ13DIC), elemental ratios and optical properties (absorption) were used as proxies to identify different C sources. Property–salinity relationships revealed regions of approximately linear mixing (e.g., alkalinity) or net sources or sinks (e.g., DOC). DIC speciation and isotopic distributions demonstrated dynamic source–sink reaction processes within the estuary. DOC was the major form of organic carbon representing mixtures of terrestrial sources (e.g., pore water, litter leaching) and very high concentration (400–800 µM) compared to other mangrove settings (e.g. Brazilian, Sundarbans, African). Highly negative δ13POC (− 40‰) in the riverine part presumably suggests the role of freshwater phytoplankton in the dry season and methanotrophic sources derived from senescent mangrove deposits or upstream hydrothermal dam during the wet season. Microphytobenthos and marine phytoplankton were the primary sources of POC inshore and DOC offshore, respectively. Mangrove products and benthic microalgae dominated estuarine sources of C in FG coastal waters (~ 10 km, inner shelf region), and there was extensive exchange of C between forest and tidal flat and the estuarine reservoirs.

- Abstract
Aging research aims at developing therapies that delay normal aging processes and some related pathologies. Recently, many compounds and extracts from natural products have been shown to slow aging and/or extend lifespan. Marine sponges and their associated microorganisms have been found to produce a wide variety of bioactive secondary metabolites; however, those from the Southwest of the Indian Ocean are much less studied, especially regarding anti-aging activities. In this study, the microbial diversity of the marine sponge Scopalina hapalia was investigated by metagenomic analysis. Twenty-six bacterial and two archaeal phyla were recovered from the sponge, of which the Proteobacteria phylum was the most abundant. In addition, 30 isolates from S. hapalia were selected and cultivated for identification and secondary metabolites production. The selected isolates were affiliated to the genera Bacillus, Micromonospora, Rhodoccocus, Salinispora, Aspergillus, Chaetomium, Nigrospora and unidentified genera related to the family Thermoactinomycetaceae. Crude extracts from selected microbial cultures were found to be active against seven clinically relevant targets (elastase, tyrosinase, catalase, sirtuin 1, Cyclin-dependent kinase 7 (CDK7), Fyn kinase and proteasome). These results highlight the potential of microorganisms associated with a marine sponge from Mayotte to produce anti-aging compounds. Future work will focus on the isolation and the characterization of bioactive compounds. © 2020 by the authors. Licensee MDPI, Basel, Switzerland.

Introduction La qualite de vie (QdV) devient un enjeu majeur dans l’etude de la progression des maladies, notamment des maladies neurologiques incurables caracterisees par une degenerescence progressive telles que l’atrophie multi-systematisee (AMS). Son etude apporte des informations cruciales sur le ressenti des patients et permet aux cliniciens de mieux les accompagner face a l’aggravation de leur etat de sante. Cependant, la QdV est un concept complique a apprehender, possiblement multidimensionnel et quantifie par un ensemble d’items categoriels. Les methodes statistiques appropriees a son etude restent encore peu diffusees en sante du fait de la complexite des donnees. Dans ce travail, nous decrivons les differentes etapes mises en œuvre pour etudier l’evolution d’une echelle de QdV au travers de l’evolution de l’echelle MSA-QoL specifique a l’AMS. Methodes Les donnees sont issues de la cohorte francaise AMS incluant plus de 600 patients diagnostiques dans le centre de reference maladie rare des CHU de Bordeaux et de Toulouse. Les patients ont un suivi annuel standardise incluant l’evaluation de la QdV par l’echelle MSA-QoL composee de 40 items, quotes de 0 a 4, evaluant les spheres motrices, non-motrices et emotionnelles/sociales. Notre methodologie s’est scindee en quatre etapes : – identifier les dimensions pertinentes mesurees par l’echelle et les items les constituants, par la methode PROMIS basee sur une analyse factorielle ; – etudier la trajectoire de chaque dimension et ses determinants par un modele IRT adapte aux donnees longitudinales ; – decrire la hierarchie d’atteintes des items de chaque dimension et la confronter a la progression de la pathologie (ici le degre de handicap) ; – quantifier l’apport de chaque item a chaque stade de la maladie par le calcul du pourcentage d’information de Fisher et identifier les plus informatifs. Resultats Nous avons identifie quatre dimensions de QdV : motrice, alimentaire, non-motrice et emotionnelle. Ces dernieres, deja partiellement atteintes en debut de suivi, s’aggravent au cours de la maladie, avec une evolution beaucoup plus rapide de la dimension motrice par rapport aux autres dimensions plus progressives. Les vitesses d’aggravation de ces dimensions different notamment selon le sexe, l’âge et les sous-diagnostics de la maladie. Enfin, l’analyse de l’information met en evidence certains items de QdV plus informatifs sur la progression de l’AMS, tels que ceux associes aux mouvements pour la dimension motrice, et la fatigue, les douleurs localisees et l’inconfort la nuit pour la dimension non-motrice. Conclusion Nous apportons avec cette etude de cas concrete, une methodologie complete permettant l’analyse de donnees longitudinales de QdV telles que rencontrees dans un nombre croissant d’etudes cliniques.

International audience; The internal and external mechanical environment plays an important role in tumorogenesis. As a proxy of an avas-cular early state tumor, we use multicellular spheroids, a composite material made of cells, extracellular matrix and permeating fluid. We characterize its effective rheology at the timescale of minutes to hours by compressing the aggregates with osmotic shocks and modeling the experimental results with an active poroelastic material that reproduces the stress and strain distributions in the aggregate. The model also predicts how the emergent bulk modulus of the aggregate as well as the hydraulic diffusion of the percolating interstitial fluid are modified by the preexisting active stress within the aggregate. We further show that the value of these two phenomenological parameters can be rationalized by considering that, in our experimental context, the cells are effectively impermeable and incompressible inclusions nested in a compressible and permeable matrix.

A number of trace metals play essential roles in marine ecosystem structure and biological productivity. Until recently, it has been argued that phytoplankton access primarily dissolved iron, while particulate iron was considered a refractory material with little use biologically and limited interaction with the dissolved pool. In order to assess the transfer mechanisms between sediment-sourced particulate trace metals and the dissolved pool, we conducted a 14-month incubation that reacted resuspended sediments with natural seawater, both originating from the Kerguelen area (KEOPS cruises; Southern Ocean), in the dark, and at concentrations replicating natural conditions. Three types of sediments were investigated (named BioSi, BioSi + Ca, and Basalt), mostly composed of (i) biogenic silica (bSiO2), (ii) bSiO2 and calcite, and (iii) basaltic fragments, respectively. The release of dissolved silicon (dSi), iron (dFe) and manganese (dMn) was monitored regularly throughout the incubation, as well as living bacteria density and Fe organic ligands. Depending on the origin and composition of the sediment, unique dFe and dMn fluxes were observed, including a strong decoupling between dFe and dMn. The basaltic sediment released up to 1.09 ± 0.04 nmol L−1 of dFe and 0.28 ± 0.09 nmol L−1 of dMn, while the biogenic sediments released a higher 3.91 ± 0.04 nmol L−1 and 8.03 ± 0.42 nmol L−1 of dFe and dMn, respectively. Several factors influencing the release and removal of dFe and dMn were discernable at the temporal sampling resolution of the incubation, including the structural composition of the sediment, bacterial abundance, and the formation of manganese oxides. The regular sampling over short timescales and the extended sampling over one year proved to be critical to constrain the processes and exchanges that govern the contribution of the particulate to the dissolved pools. Overall, this incubation provides a strong basis for reassessing the role of resuspended sedimentary particles in the marine biogeochemical cycles of Fe and Mn. Indeed, we show that biogenic silica, calcite-rich and basaltic particles can contribute substantial dissolved Fe and Mn to the overlying water column. In the future, the global extent of this previously overlooked external metal source should be quantified through further process studies and biogeochemical models.

Background Technological advances have improved phenotypical characterisation of blood cells, and flow cytometry is currently used in haematology, infectious disease, systemic auto-immune diseases. Abnormalities of blood B cell subset profile might provide a useful diagnostic tool in systemic auto-immune diseases, especially for primary Sjogren’s Syndrome1 in which the activated B cells to memory B cells ratio is increased. Nevertheless, we observed that some patients suffering from chronic infection had lymphocytes disturbances similar to those observed in primary Sjogren’s Syndrome. Objectives Whipple’disease (WD) is a rare, systemic, disease caused by intracellular gram positive bacterium, Tropheryma Whipplei (TW). No previous study evaluated the role of B cells in WD. The aim of this study was to analyse whether the circulating blood B cell subset disturbances is characteristic of WD. Methods We collected characteristics of all patients coming for inflammatory rheumatism in our rheumatology department between April 2010 and December 2016. All of them had systematically routine examination, immunological tests, lymphocyte subsets in peripheral blood by flow cytometric analysis. We selected among this population those patients who also had PCR for TW for suspicion of WD, and compared the distribution of lymphocyte subsets of those with and without WD. Then, we evaluated their diagnostic value for WD using a ROC curve. Results Among 3494 patients with inflammatory rheumatism, 121 patients (212 visits) had a suspicion of WD and the diagnosis of WD was retained by an expert rheumatologist for 9 (7.4%) (22 visits). T cells and NK cells were not different whereas percentage of circulating memory B cells (IgD-CD38low) was lower (18.0%±9.7% vs 26.0±14.2%, p=0.041) and the ratio of activated B cells to memory B cells higher (4.4±2.0 vs 2.9±2.2, p=0.023), in patients compared with controls. More precisely, the analysis of the frequency of peripheral blood B cells showed that IgD +CD27 – naive B cells were higher (66.2%±18.2% vs 54.6±18.4%, p=0.047) and IgD-CD27 +switched memory B cells lower (13.3%±5.7% vs 21.4±11.9%, p=0.023), in patients compared with the controls. The best diagnostic value was obtained for the IgD +CD27- naive B cells (cut off 70.5, sensitivity 73%, specificity 80%). Conclusions Our study provides data on blood B cells disturbances and a first step towards understandings of immunological abnormalities in WD. These disturbances provide guidance for diagnosis and allow physiopathological hypothesis. Reference [1] Binard A, Le Pottier L, Devauchelle-Pensec V, Saraux A, Youinou P, Pers J-O.

International audience; Context: Telemedicine is proposed as a useful tool to increase efficiency, improve access and the quality of care. The widespread use of telemedicine has created the need to evaluate its efficiency. This implies that we need use appropriate evaluation methods. In this context, what lessons can be learned from previous economic evaluation studies? The first objective was to explore economic evaluation studies of telemedicine in terms of their descriptive analysis, methodological quality and the main shortcomings of the methodology. The second objective was to identify a standardized framework for economic evaluation, with a view to providing a tool for policymakers and stakeholders. Method: The analysis was based on a review of the literature from 2000 to 2013. We identified 286 potential articles. The selection and analysis of the studies led to excluding 159 articles. After reviewing the full-text articles, 74 studies that implemented an economic evaluation for a telemedicine project and 27 systematic reviews on economic evaluation (including 5 French ones) remained. 26 partial economic evaluations that only focus on costs were excluded. A standardised analysis framework was developed in collaboration with a methodological working group, based on the results of literature review and the study of existing projects. Results: Two main results appear: an important heterogeneity of the publications which leads to the impossibility of comparing the results and adjudicate on a possible efficiency of telemedicine and a poor quality of the cost-effectiveness method used for telemedicine. These findings are consistent with those of the systematic reviews of the literature examined. An update of the literature review was made from 2013 to 2017. Economic evaluation protocols are actually more sophisticated. The use of economic evaluation to assess the economic consequences of telemedicine interventions requires adequate use of standard methodology. The French National Authority for Health has proposed the development of an impact matrix showing the expected effects of telemedicine on the various stakeholders. Conclusions: While the results of economic evaluation studies can be criticized in terms of methodology and are not very decisive, the recommendations relating to implementing economic evaluations were identified to promote a coherent development of economic evaluations. The methodological framework presented here is not considered as an end in itself but rather than the beginning of what is hoped will be an ongoing process of telemedicine evaluation.

International audience; Introduction: Telestroke system allows the sharing of medical information and the remote administration of fibrinolysis to a person who has suffered a stroke, regardless of their location. The objective of the present study is to provide a tool to model different care scenarios of a stroke patient and to measure results in terms of efficiency and cost. Materials and methods: We established a decision tree-based analytical model representing five scenarios. The baseline scenario represented the current management of patients in eight accident and emergency departments, two primary stroke units (PSUs) and a comprehensive stroke unit (SU), all connected via a telemedicine tool. Four variants of this first scenario were proposed, based or not on telemedicine. Efficiency criteria were thrombolysis rate; rate of return home; and quality-adjusted life-years. Costs were based on actual patient resources used. Results: Once the model parameters were identified, the results were used to compare the scenarios in terms of cost and efficiency. The different assumptions, transition probabilities, data sources, and efficiency and modelling costs are discussed. Discussion: This model provides a medico-economic evaluation of the Telestroke system. It is an adjustable and scalable model that can be applied in other regions and adapted to other medical fields. Conclusion: telemedicine appears to be a cost-effective modality for the management of stroke. The modelling makes it possible to take into account the regional specificities and the organization of the sector within the territory.

Background New consensual classification criteria for primary Sjogren9s syndrome (pSS) have been recently developed and endorsed by ACR and EULAR. They differ substantially from previously used AECG criteria in that they consider systemic involvement (defined as ESSDAI score ≥1) as well as sicca symptoms as entry criteria before applying a weighted score. Evaluation of the concordance and differences between the two sets of criteria in independent patient populations is mandatory to establish how future clinical studies using the new criteria will be comparable to previously published studies. Major salivary gland ultrasonography (SGUS) has demonstrated promising diagnostic performance in previous studies, but was not included in these new classification criteria. Methods This cross-sectional study was conducted in the monocentric Brittany cohort (DIApSS cohort) of patients with suspected pSS (sicca symptoms, parotidomegaly or extraglandular manifestations suggestive of pSS). All patients had standardized clinical examination, basic biology, immunological tests and minor labial salivary gland biopsy. SGUS in mode B was performed by the same experienced operator, who was blinded to the diagnosis. Agreement between the two sets of criteria was assessed using Cohen9s κ coefficient and the characteristics of discordant patients were detailed. Results 290 patients were prospectively included between 2006 and 2016. Mean age was 55.6±13.2 years, 92.1% were female and mean duration of the symptoms 6.0±6.6 years. More patients fulfilled ACR/EULAR criteria (n=125, 43.1%) than AECG criteria (n=114, 39.3%). 114 patients (39.3%) fulfilled both criteria, 11 (3.8%) fulfilled ACR/EULAR only, 0 AECG only and 165 (56.9%) none of the criteria. Concordance between both criteria was good (kappa=0.9). Compared to patients fulfilling both criteria, patients fulfilling ACR/EULAR but not AECG criteria (n=11) had similar age, similar symptom duration, but less frequent sicca symptoms (eye dryness 18.2% versus 96.5%; mouth dryness 54.5% versus 97.4%, p Conclusions Agreement between AECG criteria and new ACR/EULAR criteria is good suggesting that they select quite similar patients. ACR/EULAR criteria display a slightly higher sensitivity and are able to detect more patients with systemic involvement, but some of these patients did not have pSS according to the physician diagnosis. As previously demonstrated for AECG criteria, SGUS inclusion into ACR/EULAR criteria may further enhance their sensitivity. Disclosure of Interest None declared

To investigate the concordance between walking (WS) and psychomotor speed (PS), correlates of both tasks, and their capacity to predict mortality in the elderly. Seven-year cohort study of 1,365 community-dwelling subjects aged 65-95 years, participating in the Bordeaux sample of the Three City Study, a French prospective cohort designed to evaluate the risk of cognitive decline attributable to vascular risk factors. Participants completed a battery of cognitive assessments including time to complete Trail Making Test A used as a PS measure, and a measure of WS. Socio-demographic determinants, co-morbidities, functional and cognitive evaluation, and incident mortality were taken into account. Mean age was 75.7 (SD ± 5.4) years. WS and TMT-A speed have very low concordance (kappa coefficient=.05). The correlates of each measure were different: mostly clinical co-morbidities for WS, and mostly cognition and function for TMT-A speed. However, TMT-A speed and WS are both independent predictors of death after seven years of follow-up. WS and TMT-A speed could be considered as two different dimensions of age-related slowness, but both performances were associated with higher risk of mortality.

The rehydroxylation (RHX) dating method applicable to virtually all baked clay fragments still requires testing and new developments. Here, we have obtained new weighing measurements from Syrian medieval ceramic fragments. In particular, they allow us to illustrate the scatter in RHX behaviour that may exist between different potsherds of the same age and found at the same archaeological site, thus having experienced the same effective lifetime temperature, and even between samples collected from the same artefact. Thanks to a so-called time-span analysis, we also report on some complexities in data sets previously obtained by Wilson et al. (2009, 2012, 2014).

To investigate the association of the change in practice of leisure and social activities with dementia risk taking into account the evolution of cognitive performances. From the PAQUID prospective cohort re-examined every 2 years until the 20-year follow-up since 1988, 1461 subjects were seen at 10th year of follow-up. Engagement in 10 leisure and social activities was collected at baseline and at the 10-year follow-up visit for 805 subjects. Four categories of change in activity engagement were considered: subjects who remained active; remained inactive; became inactive and became active. Adjustment on confounders (age, gender, educational level, diabetes, stroke and depression) and rate of evolution of cognitive performances was made with the multivariate Cox proportional hazards model. Time to incident cases of dementia occurring between the 10th and the 20th year of follow-up. A total of 258 incident dementia cases were documented. The risk of dementia was lower for subjects remaining or becoming active (cumulative risk of dementia: 30%) compared to those remaining or becoming inactive (52% and 42%, respectively) (p

Resume Introduction Non traitee ou non suivie, l’hypertension arterielle (HTA) accroit le risque d’accident cardiovasculaire de 25 %. L’HTA concerne un francais sur quatre, entre 20 et 65 ans, mais la moitie l’ignore. En effet, le plus souvent asymptomatique, l’hypertension n’est pas toujours detectee aussitot qu’il le faudrait au regard des risques dont elle est porteuse. S’il apparait essentiel de detecter et traiter l’HTA, il est aussi crucial de se mettre en capacite de bien la controler pour prevenir ses complications. C’est pour repondre a cette problematique que Vigisante, un programme de depistage de l’HTA en entreprise et de prise en charge a domicile des salaries hypertendus grâce a des dispositifs communicants et une plate-forme medicalisee a ete deploye. Ce deploiement a ete mene dans le cadre d’une etude experimentale aupres de 50 entreprises de la region Nord-Pas de Calais entre octobre 2011 et avril 2013. L’un des objectifs de ce pilote etait de verifier que le cadre de l’entreprise est adapte pour servir de point de depart a la mise en place d’un programme de suivi medical utilisant les nouvelles technologies d’information et de communication appliquees a la sante. Methode La campagne de depistage de 8 mois a ete operee par une equipe d’infirmieres mises a disposition par Vigisante sur le lieu et pendant le temps de travail, en collaboration avec l’entreprise et les medecins du travail. Elle devait permettre d’inclure les salaries hypertendus connus ou presentant une tension arterielle ≥ 140/90 mmHg. Apres signature du consentement et accord de leur medecin traitant, les participants etaient suivis et accompagnes pendant une duree maximum de 18 mois. Ils suivaient le protocole d’automesure tensionnelle tel que defini par la Societe francaise d’hypertension arterielle, ainsi qu’un programme d’accompagnement hygieno-dietetique intensif adapte au profil de risque. Au terme du programme, des enquetes de satisfaction ont ete menees aupres des participants, de leur medecin traitant et des entreprises. Resultats Vigisante a ete propose a 22 789 salaries actifs. Parmi, 4459 ont participe volontairement au 1 er rendez-vous de depistage. Neuf cent quatre salaries hypertendus se sont presentes au second rendez-vous de depistage et 669 ont donne leur accord pour etre suivis et accompagnes par Vigisante. Quarante et un pour cent des participants avaient une hypertension connue et 59 % une HTA detectee au moment de l’inclusion dans le programme. Cinq cent quarante-neuf medecins traitants ont donne leur accord pour le programme parmi lesquels 227 ont accepte de pratiquer la telesurveillance. La qualite globale du programme a ete jugee « satisfaisante » voire « tres satisfaisante » par 85 % des patients et 96 % des entreprises. Soixante-neuf pour cent des medecins traitants ont constate un impact favorable de Vigisante sur la sante globale de leurs patients. Conclusion La methodologie de deploiement proposee par Vigisante constitue un mode alternatif et pertinent de reperage des risques de sante, a meme d’accelerer le diagnostic et la prise en charge par le medecin traitant dans le cadre du parcours de soins.

[1] Ten archeointensity results have been obtained from brick and ceramic fragments collected in France and precisely dated to between the tenth and eighteenth centuries. Intensity experiments were performed using the Triaxe protocol taking into account cooling rate and thermoremanent magnetization anisotropy effects. Together with our previous results from France and Belgium, we computed a geomagnetic field intensity variation curve for Western Europe covering the past 1100 years. This curve is characterized by a general decreasing trend at the millennial timescale punctuated by three short intensity peaks, during the twelfth century, around 1350–1400 AD and ∼1600 AD. A similar evolution but with smoother variations due to data scatter is also observed in Western Europe and to a lesser extent in Eastern Europe when all available archeointensity data fulfilling quality criteria are used. Comparison of our archeointensity variation curve with the climatic record derived from fluctuations in length of the Swiss glaciers shows a good temporal concordance between all geomagnetic field intensity maxima detected in Western Europe over the past millennium and colder episodes. A comparison is further discussed between these intensity maxima and episodes of low rates of 14C production. A common pattern of variations between both records is recognized between the middle of the tenth and of the beginning of eighteenth centuries. If significant, such coincidences suggest a dual geomagnetic and solar origin for the century-scale climate and radionuclide production variations during at least the past millennium.

Aim Diabetes is known to impair health-related quality of life (HrQol). Our aim was to analyse a comprehensive set of potential determinants of HrQol in a large sample of patients with diabetes. Methods This study is based on the ENTRED 2007 study, a representative sample of adults (18 years and older) with diabetes. Data were extracted from postal self-reported questionnaires (from patients and medical practitioners) and from reimbursements from the National health insurance data system. HrQol was assessed with the MOS SF-12 for mental (MCS) and physical (PCS) component summaries. Multivariate linear regression models were used to analyse the variables associated with HrQol. Results SF-12 MCS and PCS were available in 2832 patients with T2DM, with a mean age 64 years (1715 males, 56%). Lower income, severe hypoglycaemic episodes, hospitalisation ≥24 h, instrumental daily living (IADL) restriction, low satisfaction for social support and an HbA1c within the 8.1–10.0% range were associated with lower MCS rating, whereas an older age and male gender were associated with higher MCS. Older age, female sex, higher BMI, lower income, insulin treatment, macrovascular complications, severe hypoglycaemic episodes, hospitalisation ≥24 h, and IADL restriction were associated with lower PCS values whereas having no need for social support was associated with higher PCS values. Discussion HrQol associated factors are multiple but mainly linked with socio-demographic factors, diabetes complications and satisfaction for social support. A patient centred approach should be tested to prevent impairment of HrQol and thus to decrease the burden of diabetes. Assessment of social support should be included.

International audience; The SPOT 6-7 satellite ground segment includes a systematic and automatic cloud detection step in order to feed a catalogue with a binary cloud mask and an appropriate condence measure. However, current approaches for cloud detection, that are mostly based on machine learning and hand crafted features, have shown lack of robustness. In other tasks such as image recognition, deep learning methods have shown outstanding results outperforming many state-of-the-art methods. These methods are known to produce a powerful representation that can capture texture, shape and contextual information. This paper studies the potential of deep learning methods for cloud detection in order to achieve state-of-the-art performance. A comparison between deep learning methods used with classical handcrafted features and classical convolutional neural networks is performed for cloud detection. Experiments are conducted on a SPOT 6 image database with various landscapes and cloud coverage and show promising results.

International audience; There is agreement that elderly people complain about word finding difficulties, particularly proper names. However, few studies have focused on the prevalence of this complaint in the general population, nor is it clearly known whether it is predictive of dementia. The aim of this study was to fill this gap using the PAQUID cohort. 1,838 people aged 65 or more completed questionnaires and neuropsychological evaluation regularly during 13 years. Results show that the complaint about proper name retrieval concerns 64% of people aged above 65 years, and the complaint about common names 30%. The complaint was not associated with enhanced risk of dementia, whereas short naming tests were. Only a marginal relation was found between these naming tests and word retrieval complaint. This study emphasizes the importance of proper name retrieval complaint in the general population and suggests that elderly subjects can be reassured in the absence of other symptoms.

Background/Aims: This study was designed to develop a practical risk score for predicting 5-year survival after the diagnosis of dementia. Methods: Using the Paquid Study (prospective, population-based, long-term cohort study), we created a prognosis score with incident cases of dementia and validated it in another prospective, population-based, long-term cohort study, the Three City Study. -Results: Among the 3,777 subjects enrolled in the Paquid Study, 454 incident cases of dementia were included in this study. After a 5-year follow-up period, 319 (70.3%) were deceased. The score was constructed from three independent prognostic variables (gender, age at diagnosis and number of ADL restricted). The discriminant ability of the score was good with a c index of 0.754. Sensitivity was 64.7% and specificity 76.3%. In the validation cohort, the discriminant ability of the prognostic score with c statistics was 0.700. Sensitivity was 26.3% and specificity 95.4%. Conclusions: The prognostic factors selected in the predictive model are easily assessable, so this simple score could provide helpful information for the management of dementia, particularly to identify patients with duration of the disease greater than 5 years.

We present a determination of the gluon polarisation Delta g/g in the nucleon, based on the longitudinal double-spin asymmetry of DIS events with Q(2) > 1 (GeV/c)(2) including a pair of large transverse-momentum hadrons in the final state. The data were obtained by the COMPASS experiment at CERN using a 160 GeV/c polarised muon beam scattering off a polarised (LiD)-Li-6 target. The gluon polarisation is evaluated by a Neural Network approach for three intervals of the gluon momentum fraction x(g) covering the range 0.04 < x(g) < 0.27. The values obtained at leading order in QCD do not show any significant dependence on x(g). Their average is Delta g/g = 0.125 +/- 0.060 (stat.) +/- 0.063 (syst.) at average x(g) = 0.09 and a scale of mu(2) = 3 (GeV/c)(2).

A search is performed for a Higgs boson produced in association with a Z boson and decaying into two photons, using the L3 data collected at LEP at a centre-of-mass energy of 189 GeV. All decay modes of the Z are considered. No signal is observed and limits on the branching fraction of the Higgs boson decay into two photons as a function of the Higgs mass are derived assuming a Standard Model production rate. A lower limit on the mass of a fermiophobic Higgs is set at 94.9 GeV at 95% confidence level., Facultad de Ciencias Exactas

The Standard Model Higgs boson is searched for in 233.2 pb−1 of data collected by the L3 detector at centre of mass energies from 192 GeV to 202 GeV. These data are consistent with the expectations of Standard Model processes and no evidence of a Higgs signal is observed. A lower limit on the mass of the Standard Model Higgs boson of 107.0 GeV is set at the 95% confidence level., Facultad de Ciencias Exactas

The S matrix ansatz is a rigorously model independent approach to describe the cross-sections and asymmetries in e+e- annihilation. Using the cross-sections and asymmetries measured with the L3 detector during the 1990 and 1991 running period, we determine the mass and the width of the Z boson, the contributions of the Z exchange and of the yZ interference. Including the polarization of the t lepton in the analysis, the leptonic helicity amplitudes of the scattering process are determined assuming lepton universality. The results are compared with other model independent ansatzes as realized in ZFITTER. A systematic bias of the Z mass due to the yZ interference term is detected, which leads to an underestimation of the error on mz for model independent determinations., Facultad de Ciencias Exactas

The process eqeyaWqWyg is analysed using the data collected with the L3 detector at LEP at a centre-of-mass energy of 188.6 GeV, corresponding to an integrated luminosity of 176.8 pby1 . Based on a sample of 42 selected WqWy candidates containing an isolated hard photon, the WqWyg cross section, defined within phase-space cuts, is measured to q y be: s WW s290"80"16 fb, consistent with the Standard Model expectation. Including the process e e anngg, limits g are derived on anomalous contributions to the Standard Model quartic vertices WqWygg and WqWyZg at 95% CL: y0.043 GeVy2-a rL2-0.043 GeVy2 , y0.08 GeVy2-a rL2-0.13 GeVy2 , y0.41 GeVy2-a rL2-0.37 GeVy2, Facultad de Ciencias Exactas

We present results obtained from a study of the structure of hadronic events recorded by the L3 detector at various centre-of-mass energies. The distributions of event shape variables and the energy dependence of their mean values are measured from 30 GeV to 189 GeV and compared with various QCD models. The energy dependence of the moments of event shape variables is used to test a power law ansatz for the non-perturbative component. We obtain a universal value of Ž 2 the non-perturbative parameter a s 0.537 ± 0.073. From a comparison with resummed O(αs2)QCD calculations, we 0 s determine the strong coupling constant at each of the selected energies. The measurements demonstrate the running of αs as expected in QCD with a value of αs(mZ) = 0.1215 ± 0.0012 (exp) ± 0.0061 (th)., Facultad de Ciencias Exactas

Extra spatial dimensions are proposed by recent theories that postulate the scale of gravity to be of the same order as the electroweak scale. A sizeable interaction between gravitons and Standard Model particles is then predicted. Effects of these new interactions in boson and fermion pair production are searched for in the data sample collected at centre-of-mass energies above the Z pole by the L3 detector at LEP. In addition, the direct production of a graviton associated with a Z boson is investigated. No statistically significant hints for the existence of these effects are found and lower limits in excess of 1 TeV are derived on the scale of this new theory of gravity, Facultad de Ciencias Exactas

A search for rare charmless decays of B0d and B0s mesons has been performed in the exclusive channels B0d(s) →ηη0, B0d(s) →ηπ0 and B0d(s) →π0π0. The data sample consisted of three million hadronic Z decays collected by the L3 experiment at LEP from 1991 through 1994. No candidate event has been observed and the following upper limits at 90% confidence level on the branching ratios have been set: Br(B0d→ηη) −4, Br(B0s →ηη) < 1.5 x 10−3, Br(B0d→ηπ0) < 2.5 x 10−4, Br(B0s→ηπ0) < 1.0 x 10−3, Br(B0d→π0π0) < 6.0 x 10−5, Br(B0s→π0π0) < 2.1 x 10−4. These are the first experimental limits on Bd0→ηη and on the Bs0 neutral charmless modes., Facultad de Ciencias Exactas

Beyond the well-known effect of educational level on cognitive performances, the present study investigates the specific effect of literacy acquisition independently of education.A sample of 175 unschooled elderly participants was selected from a larger Mexican population-based cohort study.The sample of 175 subjects who never went to school was divided in two groups: 109 who never acquired literacy skills and 66 who declared having acquired reading and writing abilities.Cognitive performances on commonly used tests (mini mental state examination, Isaacs set test, free and cued selective reminding test and clock-drawing test) were compared between the two groups taking into account several potentially confounding factors.The participants with reading and writing skills performed better than their counterparts in most tests, even though no difference was observed for the Isaacs Set Test and the delayed recall of the free and cued selective reminding test.Writing and reading skills in elderly people with no formal education influence performances in very commonly used test. Not only educational level but also literacy acquisition should be taken into account when conducting cognitive assessment in very low educated elderly people.

Background: Recently, we demonstrated that the glycoprotein opticin is anti-angiogenic. Here, the underpining mechanism is explored. Results: By binding to collagen, opticin competitively inhibits integrin-mediated endothelial cell adhesion. Conclusion: Opticin inhibits angiogenesis by weakening endothelial cell adhesion to the surrounding extracellular matrix. Significance: Elucidating the regulatory mechanisms of angiogenesis is important for understanding pathology and drug discovery., Opticin is an extracellular matrix glycoprotein that we identified associated with the collagen network of the vitreous humor of the eye. Recently, we discovered that opticin possesses anti-angiogenic activity using a murine oxygen-induced retinopathy model: here, we investigate the underlying mechanism. Using an ex vivo chick chorioallantoic membrane assay, we show that opticin inhibits angiogenesis when stimulated by a range of growth factors. We show that it suppresses capillary morphogenesis, inhibits endothelial invasion, and promotes capillary network regression in three-dimensional matrices of collagen and MatrigelTM. We then show that opticin binds to collagen and thereby competitively inhibits endothelial cell interactions with collagen via α1β1 and α2β1 integrins, thereby preventing the strong adhesion that is required for proangiogenic signaling via these integrins.

Objective: To examine associations between metabolic syndrome (MetS) and its individual components with risk of cognitive decline on specific cognitive functions. Methods: Participants were 4,323 women and 2,764 men aged 65 and over enrolled in the longitudinal Three-City Study. Cognitive decline, defined as being in the worst quintile of the distribution of the difference between baseline score and either 2- or 4-year follow-up, was assessed by the Mini-Mental State Examination (MMSE, global cognitive function), the Isaacs Set Test (IST, verbal fluency), and the Benton Visual Retention Test (BVRT, visual working memory). MetS was defined by National Cholesterol Education Program–Adult Treatment Panel III criteria (at least 3 of 5 cardio-metabolic abnormalities: hypertension, high waist circumference, hypertriglyceridemia, low high-density lipoprotein [HDL] cholesterol, hyperglycemia). Proportional hazards models were adjusted for age, gender, educational level, center, baseline cognitive score, APOE4 genotype, and other potential confounders. Results: MetS at baseline was associated with an increased risk of cognitive decline on MMSE (hazard ratio [HR] = 1.22 [1.08–1.37]; p = 0.001) and BVRT (HR = 1.13 [1.01–1.26]; p = 0.03) but not on IST (HR = 1.11 [0.95–1.29]; p = 0.18). Among MetS components, hypertriglyceridemia and low HDL cholesterol were significantly associated with higher decline on MMSE; diabetes, but not elevated fasting glycemia, was significantly associated with higher decline on BVRT and IST. Conclusions: MetS as a whole and several of its components had a negative impact on global cognitive decline and specific cognitive functions in older persons.

International audience; Background: Worldwide, degenerative eye diseases (age-related maculopathy (ARM), cataract, glaucoma) are the main causes of visual impairment and blindness, which contribute to disability in the elderly. Mainly three types of nutritional factors are investigated for their potential protection against eye ageing: antioxidants; lutein and zeaxanthin (carotenoids which accumulate specifically in the eye); omega 3 polyunsaturated fatty acids. Few epidemiological studies have been conducted in this field, particularly in Europe. Objective: The Alienor (Antioxydants, Lipides Essentiels, Nutrition et maladies OculaiRes) Study aims at assessing the associations of eye diseases with nutritional factors, determined from plasma measurements and estimation of dietary intakes. Design, setting and participants: Subjects were recruited in Bordeaux (France) from the ongoing population-based 3C study. In 2006-2008, 963 subjects from the 3C Study, aged 73 years or more, had an eye examination and will have follow-up eye examinations every 2 years. Measurements: Vascular, genetic and nutritional factors were assessed at baseline (1999-2001) and follow-up examinations of the 3C Study. Eye diseases were classified according to international classifications. Results: Nutritional status and vascular disease and risk factors were similar between participants and non participants, except for a slight difference in plasma triglycerides and HDL-cholesterol. As expected, the prevalence of eye diseases was high: early and late ARM (28.4 % and 5.6 %, respectively), open-angle glaucoma and treated ocular hypertension (4.8 % and 10.0 %, respectively), cataract extraction (45.2 %), retinopathy (8.4 %), retinal vein occlusion (1.1 %), epiretinal membrane (3.9 %), current use of artificial tears (17.3 %). Conclusions: This study confirms the high prevalence of eye diseases in the elderly. Its main strength is the combination of nutritional, vascular and genetic information, collected over a 7 year period of time before the first eye examination. It may help design future interventional studies, which might be common with other age-related disorders, because of common nutritional factors.

The inclusive double-spin asymmetry, A 1 p , has been measured at COMPASS in deep-inelastic polarised muon scattering off a large polarised NH3 target. The data, collected in the year 2007, cover the range Q 2 > 1 ( GeV / c ) 2 , 0.004 x 0.7 and improve the statistical precision of g 1 p ( x ) by a factor of two in the region x 0.02 . The new proton asymmetries are combined with those previously published for the deuteron to extract the non-singlet spin-dependent structure function g 1 NS ( x , Q 2 ) . The isovector quark density, Δ q 3 ( x , Q 2 ) , is evaluated from a NLO QCD fit of g 1 NS . The first moment of Δ q 3 is in good agreement with the value predicted by the Bjorken sum rule and corresponds to a ratio of the axial and vector coupling constants | g A / g V | = 1.28 ± 0.07 ( stat . ) ± 0.10 ( syst. ) .

We present a measurement of semi-inclusive spin asymmetries for positively and negatively charged hadrons from deep inelastic scattering of polarised muons on polarised protons and deuterons in the range $0.003$1 GeV$^2$. Compared to our previous publication on this subject, with the new data the statistical errors have been reduced by nearly a factor of two. From these asymmetries and our inclusive spin asymmetries we determine the polarised quark distributions of valence quarks and non-strange sea quarks at $Q^2$=10 GeV$^2$. The polarised $u$ valence quark distribution, $\Delta u_v(x)$, is positive and the polarisation increases with $x$. The polarised $d$ valence quark distribution, $\Delta d_v(x)$, is negative and the non-strange sea distribution, $\Delta \bar q(x)$, is consistent with zero over the measured range of $x$. We find for the first moments $\int_0^1 \Delta u_v(x) dx = 0.77 \pm 0.10 \pm 0.08$, $\int_0^1 \Delta d_v(x) dx = -0.52 \pm 0.14 \pm 0.09$ and $\int_0^1 \Delta \bar q(x) dx= 0.01 \pm 0.04 \pm 0.03$, where we assumed $\Delta \bar u(x) = \Delta \bar d(x)$. We also determine for the first time the second moments of the valence distributions $\int_0^1 x \Delta q_v(x) dx$., Comment: 17 pages

International audience; The SPOT 6-7 satellite ground segment includes a systematic and automatic cloud detection step in order to feed a catalogue with a binary cloud mask and an appropriate confidence measure. In order to significantly improve the SPOT cloud detection and get rid of frequent manual re-labelings, we study a new automatic cloud detection technique that is adapted to large datasets. The proposed method is based on a modified distributed boosting algorithm. Experiments conducted using the framework Apache Spark on a SPOT 6 image database with various landscapes and cloud coverage show promising results.

We present a new measurement of the virtual photon proton asymmetry $A_1^{\rm p}$ from deep inelastic scattering of polarized muons on polarized protons in the kinematic range $0.0008 < x < 0.7$ and $0.2 < Q^{2} < 100$ GeV$^{2}$. With this, the statistical uncertainty of our measurement has improved by a factor of $2$ compared to our previous measurements. The spin-dependent structure function $g_{1}^{\rm p}$ is determined for the data with $Q^{2} > 1$ GeV$^{2}$. A perturbative QCD evolution in next-to-leading order is used to determine $g_1^{\rm p}(x)$ at a constant $Q^2$. At $Q^{2} = 10$ GeV$^{2}$ we find, in the measured range, $\int_{0.003}^{0.7} g_{1}^{\rm p}(x){\rm d}x = 0.139 \pm 0.006~({\rm stat})\pm 0.008~({\rm syst)} \pm 0.006~({\rm evol})$. The value of the first moment $\Gamma_{1}^{\rm p} = \int_{0}^{1} g_{1}^{\rm p}(x){\rm d}x$ of $g_{1}^{\rm p}$ depends on the approach used to describe the behaviour of $g_{1}^{\rm p}$ at low $x$. We find that the Ellis-Jaffe sum rule is violated. With our published result for $\Gamma_{1}^{\rm d}$ we confirm the Bjorken sum rule with an accuracy of $\approx 15\%$ at the one standard deviation level.

We present a new measurement of the spin-dependent structure function $g_{1}^{\rm d}$ of the deuteron from deep inelastic scattering of 190 GeV polarized muons on polarized deuterons. The results are combined with our previous measurements of $g_{1}^{\rm d}$. A perturbative QCD evolution in next-to-leading order is used to compute $g_{1}^{\rm d}(x)$ at a constant $Q^{2}$. At $Q^{2} = 10$ GeV$^{2}$, we obtain a first moment $\Gamma_{1}^{\rm d} = \int_{0}^{1} g_{1}^{\rm d}{\rm d}x = 0.041 \pm 0.008$, a flavour-singlet axial charge of the nucleon $a_{0} = 0.30 \pm 0.08$, and an axial charge of the strange quark $a_{s} = -0.09 \pm 0.03$. Using our earlier determination of $\Gamma_{1}^{\rm p}$, we obtain $\Gamma_1^{\rm p} - \Gamma_1^{\rm n} = 0.183 \pm 0.035$ at $Q^2 = 10\,\mbox{GeV}^2$. This result is in agreement with the Bjorken sum rule which predicts $\Gamma_1^{\rm p} - \Gamma_1^{\rm n} = 0.186 \pm 0.002$ at the same $Q^2$.

We present a precise measurement of the deuteron longitudinal spin asymmetry A 1 d and of the deuteron spin-dependent structure function g 1 d at Q 2 1 ( GeV / c ) 2 and 4 × 10 −5 x 2.5 × 10 −2 based on the data collected by the COMPASS experiment at CERN during the years 2002 and 2003. The statistical precision is tenfold better than that of the previous measurement in this region. The measured A 1 d and g 1 d are found to be consistent with zero in the whole range of x.

We present a determination of the gluon polarization Δ G / G in the nucleon, based on the helicity asymmetry of quasi-real photoproduction events, Q 2 1 ( GeV / c ) 2 , with a pair of large transverse-momentum hadrons in the final state. The data were obtained by the COMPASS experiment at CERN using a 160 GeV polarized muon beam scattered on a polarized 6 LiD target. The helicity asymmetry for the selected events is 〈 A ∥ / D 〉 = 0.002 ± 0.019 ( stat ) ± 0.003 ( syst ) . From this value, we obtain in a leading-order QCD analysis Δ G / G = 0.024 ± 0.089 ( stat ) ± 0.057 ( syst ) at x g = 0.095 and μ 2 ≃ 3 ( GeV / c ) 2 .
