Améliorer la prise en charge de l'hypertension arterielle en favorisant la collaboration avec les pharmaciens et les infirmières [Team-based care involving pharmacists and nurses to improve the management of hypertension].

Only half of hypertensive patients has controlled blood pressure. Chronic kidney disease (CKD) is also associated with low blood pressure control, 25-30% of CKD patients achieving adequate blood pressure. The Community Preventive Services Task Force has recently recommended team-based care to improve blood pressure control. Team-based care of hypertension involves facilitating coordination of care among physician, pharmacist and nurse and requires sharing clinical data, laboratory results, and medications, e.g., electronically or by fax. Based on recent studies, development and evaluation of team-based care of hypertensive patients should be done in the Swiss healthcare system.

Optimization of floor cleaning coverage performance of a random path-planning mobile robot

Floor cleaning is a typical robot application. There are several mobile robots aviable in the market for domestic applications most of them with random path-planning algorithms. In this paper we study the cleaning coverage performances of a random path-planning mobile robot and propose an optimized control algorithm, some methods to estimate the are of the room, the evolution of the cleaning and the time needed for complete coverage.

Devenir charrùa dans l'Uruguay de l'après dictature Entre mémoires fragmentées et « sens du collectif ». Une ethnographie audiovisuelle en collaboration.

Dans cette recherche, je me suis intéressée à la genèse des rapports sociaux construisant un collectif, dans l'articulation être nommé et se nommer. En Uruguay, pays construit sur un imaginaire social dit "sans indiens", mon travail a consisté à essayer de comprendre les conditions historiques, sociales et politiques d'émergence de collectifs de personnes réclamant l'appartenance à une identité autochtone précise, l'identité charrùa. J'ai démontré qu'il s'agit d'un processus en cours, individuel et collectif, qui a des temporalités diverses, qui a néanmoins émergé depuis une vingtaine d'années, dans le contexte de la post-dictature et celui géopolitique de l'autochtonie, dans une articulation local/global. L'analyse dévoile que l'identité charrùa est l'enjeu du rapport social qui est la lutte politique contre l'exclusion. Cette identité accompagne l'état-nation depuis sa fondation. Figure duelle, cette identité contient les traces des violences internes dans un continuum de mémoires fragmentées et entrelacées. Elle est aussi promesse de devenir en tant que modèle identitaire parvenu à l'autonomie et conservant le « sens du collectif ». Anthropologue engagée, me situant dans une perspective décoloniale, j'ai proposé aux personnes avec qui j'ai effectué cette recherche, d'élaborer une ethnographie collaborative, la caméra et les films se situant au coeur du terrain, compris comme espace relationnel de construction d'une connaissance partagée. -- My research is based on the genesis of social relations which build up a collective, structured on being named and be named. My work in Uruguay, country built on a social construct called "without Indians", was to try to understand the historical, social and political conditions of emerging collectives. These claim the belonging of a precise indigenous identity, the charrua identity. I showed that the current process, which is individual and collective, with different temporalities, emerged twenty years ago, in the post-dictatorship context as well as the geopolitical context of indigeneity, in a local/global structure. The analysis reveals that the charrua identity is the stake of the social relation which is political fight against exclusion. This identity accompanies the nation state since its foundation. Dategory dual, this identity keeps the traces of the internal in the continuum of the fragmented and intertwined memories. This is also the becoming promise of an identity model, which reaches autonomy and keeps the "sense of collective". As an involved anthropologist, I worked from a decolonization point of view. I suggested that the people who went through the research with me, should work out a collaborative ethnography, the video camera and the movies being set in the middle of the fieldwork. This one is conceived as a relational space of construction of a shared knowledge.

Mobile or fixed bearing for total knee arthroplasty? Ambulatory gait analysis results

Background: Mobile-bearing knee replacements have some theoretical advantages over fixed-bearing devices. However, very few randomized controlled clinical trials have been published to date, and studies showed little clinical and subjective advantages for the mobile-bearing using traditional systems of scoring. The choice of the ideal outcome measure to assess total joint replacement remains a complex issue. However, gait analysis provides objective and quantifying evidences of treatment evaluation. Significant methodological advances are currently made in gait analysis laboratories and ambulatory gait devices are now available. The goal of this study was to provide gait parameters as a new objective method to assess total knee arthroplasty outcome between patients with fixed- and mobile-bearing, using an ambulatory device with minimal sensor configuration. This randomized controlled double-blind study included to date 14 patients: the gait signatures of four patients with mobile-bearing were compared to the gait signatures of nine patients with fixed-bearing pre-operatively and post-operatively at 6 weeks, 3 months and 6 months. Each participant was asked to perform two walking trials of 30m long at his/her preferred speed and to complete a EQ-5D questionnaire, a WOMAC and Knee Society Score (KSS). Lower limbs rotations were measured by four miniature angular rate sensors mounted respectively, on each shank and thigh. A new method for a portable system for gait analysis has been developed with very encouraging results regarding the objective outcome of total knee arthroplasty using mobile- and fixed-bearings.

Note méthodologique sur la collaboration entre praticiens dans le secteur ambulatoire. [Methodologic note on the collaboration between practitioners in the ambulatory care sector].

There are still few studies about the collaboration between ambulatory practitioners (physicians and paramedical services). Nevertheless, the interest seems to be growing for this aspect of health care; it involves indeed basic organisational problems as well as fundamental questions about quality of care and its economic implication. A basic problem is rooted in the inevitable contradiction of the efforts towards a highly qualified-i.e. specialised-care on the one hand and those towards continuity on the other hand.
