Une approche communicationnelle de la professionnalisation au sein des Instituts de formation en soins infirmiers en France
2013
Dans un contexte de fortes mutations et de réflexion autour du devenir des métiers de la santé et de l’appareil de formation qui leur est dédié en France, les formateurs et les directeurs des Instituts de Formation en Soins Infirmiers sont amenés à travailler à la construction et à la promotion du projet pédagogique de leur établissement. Au quotidien, leurs pratiques individuelles montrent combien leur lecture de la réalité de travail est singulière et se trouve en partie corrélée à leur professionnalité. A partir des significations que chacun d’eux exprime, la coopération entre ces professionnels semble se construire très progressivement à la croisée des problématiques communicationnelles…
Fuzzy motion control strategy for cooperation of multiple automated vehicles with passengers comfort
2008
This paper considers motion control for a cooperative system of automated passenger vehicles. It develops a cooperative scheme based on a decentralized planning algorithm which considers the vehicles in an initial open chain configuration. In this scheme the trajectories are intersections-free, and each trajectory is planned independently of the others. To ensure the stabilization of each vehicle in the planned trajectory, a fuzzy closed loop motion control is presented, where, based on the properties of the Fuzzy maps, the Lyapunov’s stability of the motion errors is demonstrated for all the vehicles. Based on the ISO 2631-1 standard, the saturation property of the Fuzzy maps guarantees lo…
The role of Interleukin-2 during the activation of cytotoxic T-lymphocytes
1983
Der vorliegende Artikel stellt eine Ubersicht dar Uber die derzeitigen Vorstellungen des Zusammenwirkens zellularer und humoraler Faktoren, die zu T-Zell-vermittelten zytotoxischen Immunreaktionen fuhren. Da im Ablauf derartiger Immunreaktionen hormonahnliche Wachstumsfaktoren (interleukine) eine entscheidende Rolle spielen, liegt der Schwerpunkt der Diskussion auf der Beschreibung dieser Mediatoren; insbesondere wird die Bedeutung von Interleukin-2 (Il-2) diskutiert. Il-2 ist ein losliches, nicht antigenspezifisches Glykoprotein mit einem Molekulargewicht von 15 000 Dalton (humanes Il-2) bzw. 30 000 Dalton (murines Il-2). Es wird in vitro von T-Helfer-Lymphozyten sezerniert, die in der Mau…
Physical activity of children: a global matrix of grades comparing 15 countries.
2014
The Active Healthy Kids Canada (AHKC) Report Card on Physical Activity for Children and Youth has been effective in powering the movement to get kids moving by influencing priorities, policies, and practice in Canada. The AHKC Report Card process was replicated in 14 additional countries from 5 continents using 9 common indicators (Overall Physical Activity, Organized Sport Participation, Active Play, Active Transportation, Sedentary Behavior, Family and Peers, School, Community and Built Environment, and Government Strategies and Investments), a harmonized process and a standardized grading framework. The 15 Report Cards were presented at the Global Summit on the Physical Activity of Child…
Perceived Stress and Mild Cognitive Impairment among 32,715 Community-Dwelling Older Adults across Six Low- and Middle-Income Countries
2018
<b><i>Background:</i></b> Perceived stress may be a modifiable risk factor for mild cognitive impairment (MCI) and ultimately dementia, but studies on this topic from low- and middle-income countries (LMICs) are lacking. <b><i>Objective:</i></b> We assessed the association between perceived stress and MCI in six LMICs (China, Ghana, India, Mexico, Russia, and South Africa) using nationally representative data. <b><i>Methods:</i></b> Cross-sectional, community-based data on individuals aged ≥50 years from the World Health Organization’s Study on Global Ageing and Adult Health were analyzed. The definition of MCI was base…
Clinical profile and predictors of in-hospital mortality among older patients hospitalised for COVID-19.
2020
Abstract Background the coronavirus disease 2019 (COVID-19) is characterized by poor outcomes and mortality, particularly in older patients. Methods post hoc analysis of the international, multicentre, ‘real-world’ HOPE COVID-19 registry. All patients aged ≥65 years hospitalised for COVID-19 were selected. Epidemiological, clinical, analytical and outcome data were obtained. A comparative study between two age subgroups, 65–74 and ≥75 years, was performed. The primary endpoint was all cause in-hospital mortality. Results about, 1,520 patients aged ≥65 years (60.3% male, median age of 76 [IQR 71–83] years) were included. Comorbidities such as hypertension (69.2%), dyslipidaemia (48.6%), card…
Xid-defective male (CBA/N x C57BL/6)F1 accessory cells present bovine insulin to long-term cultured F1-restricted T-cells
1982
The reactivity of H-2b-restricted murine T cells towards bovine insulin was reported to depend on the expression of Ia. W39, a private specificity of I-Ab, on antigen-presenting cells. Cells of male (CBA/N X B6)F1 mice carrying the mutation xid on the X chromosome lack IA. W39 on the cell surface. These cells are unable to present bovine insulin to primed T cells derived from female (CBA/N X B6)F1 mice. We show here that spleen cells of male (CBA/N X B6)F1 hybrids served perfectly as accessory cells for the insulin-dependent induction of a proliferative response of long-term cultured T cells with (B10 X B10.BR)F1 genotype, restricted to recognizing insulin in the context of F1-unique I-A de…
Arsenic trioxide-based therapy of relapsed acute promyelocytic leukemia: registry results from the European LeukemiaNet
2015
In 2008, a European registry of relapsed acute promyelocytic leukemia was established by the European LeukemiaNet. Outcome data were available for 155 patients treated with arsenic trioxide in first relapse. In hematological relapse (n=104), 91% of the patients entered complete hematological remission (CR), 7% had induction death and 2% resistance, 27% developed differentiation syndrome and 39% leukocytosis, whereas no death or side effects occurred in patients treated in molecular relapse (n=40). The rate of molecular (m)CR was 74% in hematological and 62% in molecular relapse (P=0.3). All patients with extramedullary relapse (n=11) entered clinical and mCR. After 3.2 years median follow-u…
Elective Cancer Surgery in COVID-19-Free Surgical Pathways during the SARS-CoV-2 Pandemic: An International, Multicenter, Comparative Cohort Study
2020
PURPOSE As cancer surgery restarts after the first COVID-19 wave, health care providers urgently require data to determine where elective surgery is best performed. This study aimed to determine whether COVID-19–free surgical pathways were associated with lower postoperative pulmonary complication rates compared with hospitals with no defined pathway. PATIENTS AND METHODS This international, multicenter cohort study included patients who underwent elective surgery for 10 solid cancer types without preoperative suspicion of SARS-CoV-2. Participating hospitals included patients from local emergence of SARS-CoV-2 until April 19, 2020. At the time of surgery, hospitals were defined as having a …
Research in China
2009
My stay in China began in November 1985 with a lecture at the opening of the Max Planck Guest Laboratory in the Institute of Cell Biology at the Chinese Academy of Sciences (CAS) in Shanghai (Hennig, 2000). It marked the beginning of 23 years of research and teaching at the Institute of Cell Biology and other universities throughout China. > Looking back after 23 years, the changes that have taken place in China could not have been predicted in 1985… In January 2001, I accepted a long‐term lectureship offered by the German Academic Exchange Service (DAAD; Bonn, Germany), which, with further support from CAS, allowed me to create my own research group within the Shanghai Institutes for Biolo…
