    Impaired regulation of extracellular matrix remodeling by matrix metalloproteinases (MMPs) and tissue inhibitor of metalloproteinase (TIMP) may contribute to vascular complications in patients with type 1 diabetes. We investigated associations between plasma MMP-1, -2, -3, -9, -10 and TIMP-1, and cardiovascular disease (CVD) or microvascular complications in type 1 diabetic patients. We also evaluated to which extent these associations could be explained by low-grade inflammation (LGI) or endothelial dysfunction (ED). Methods: 493 type 1 diabetes patients (39.5 ± 9.9 years old, 51% men) from the EURODIAB Prospective Complications Study were included. Linear regression analysis was applied to investigate differences in plasma levels of MMP-1, -2, -3, -9, -10, and TIMP-1 between patients with and without CVD, albuminuria or retinopathy. All analyses were adjusted for age, sex, duration of diabetes, Hba1c and additionally for other cardiovascular risk factors including LGI and ED. Results: Patients with CVD (n = 118) showed significantly higher levels of TIMP-1 [ÎČ = 0.32 SD (95%CI: 0.12; 0.52)], but not of MMPs, than patients without CVD (n = 375). Higher plasma levels of MMP-2, MMP-3, MMP-10 and TIMP-1 were associated with higher levels of albuminuria (p-trends were 0.028, 0.004, 0.005 and 0.001, respectively). Severity of retinopathy was significantly associated with higher levels of MMP-2 (p-trend = 0.017). These associations remained significant after further adjustment for markers of LGI and ED. Conclusions: These data support the hypothesis that impaired regulation of matrix remodeling by actions of MMP-2, -3 and-10 and TIMP-1 contributes to the pathogenesis of vascular complications in type 1 diabetes

    International audienceObjectiveTo evaluate the reliability and functional acceptability of the “Synthetic Autonomous Majordomo” (SAM) robotic aid system (a mobile Neobotix base equipped with a semi-automatic vision interface and a Manus robotic arm).Materials and methodsAn open, multicentre, controlled study. We included 29 tetraplegic patients (23 patients with spinal cord injuries, 3 with locked-in syndrome and 4 with other disorders; mean ± SD age: 37.83 ± 13.3) and 34 control participants (mean ± SD age: 32.44 ± 11.2). The reliability of the user interface was evaluated in three multi-step scenarios: selection of the room in which the object to be retrieved was located (in the presence or absence of visual control by the user), selection of the object to be retrieved, the grasping of the object itself and the robot's return to the user with the object. A questionnaire was used to assess the robot's user acceptability.ResultsThe SAM system was stable and reliable: both patients and control participants experienced few failures when completing the various stages of the scenarios. The graphic interface was effective for selecting and grasping the object – even in the absence of visual control. Users and carers were generally satisfied with SAM, although only a quarter of patients said that they would consider using the robot in their activities of daily living.ObjectifÉvaluation de la fiabilitĂ© et de l’acceptabilitĂ© de l’usage d’un robot mobile d’assistance, Synthetic Autonomous Majordomo (SAM) composĂ© d’une base mobile NĂ©obotix avec bras tĂ©lĂ©manipulateur Manus, dotĂ© d’une interface de saisie automatique d’objet.Patients et mĂ©thodesÉtude multicentrique ouverte contrĂŽlĂ©e sous l’égide de l’association APPROCHE. Vingt-neuf patients tĂ©traplĂ©giques d’ñge moyen 37,83 ± 13,3 : 23 blessĂ©s mĂ©dullaires, 2 Locked In Syndrome, 4 autres pathologies. Trente-quatre sujets tĂ©moins d’ñge moyen 32,44 ± 11,2. La fiabilitĂ© de l’interface graphique du systĂšme de commande a Ă©tĂ© Ă©valuĂ©e Ă  travers 3 scĂ©narii comportant diffĂ©rentes Ă©tapes : dĂ©signation de la piĂšce oĂč se trouve l’objet, dĂ©placement de SAM vers l’objet, dĂ©signation de l’objet Ă  saisir avec ou sans contrĂŽle visuel, saisie automatique de l’objet, dĂ©clenchement du retour de SAM. L’usage du robot et son acceptabilitĂ© ont Ă©tĂ© Ă©valuĂ©s par un questionnaire.RĂ©sultatsLe systĂšme est stable et fiable : il y a peu d’échec dans la rĂ©alisation des diffĂ©rentes Ă©tapes des scĂ©narii aussi bien pour les patients que pour les tĂ©moins. L’interface graphique est efficace pour la dĂ©signation et la saisie de l’objet. SAM a Ă©tĂ© bien accueilli par tous les utilisateurs patients et thĂ©rapeutes. Mais seuls les patients envisageraient un transfert de l’utilisation du robot en vie quotidienne
