Thérapie d’acceptation et d’engagement (ACT) et Mindfulness, un modèle de flexibilité psychologique pour la douleur chronique

2016

Resume La therapie d’acceptation et d’engagement (ACT) et la meditation en pleine conscience appelee egalement Mindfulness sont issues de la troisieme vague des therapies comportementales et cognitives (TCC). Bien que ces therapies aient suscite l’interet des cliniciens et chercheurs internationaux et qu’elles beneficient a present de solides supports empiriques appliques au domaine de la douleur chronique, l’ACT et le Mindfulness restent encore meconnus en France et encore trop peu utilises pour reduire la souffrance des patients douloureux chroniques. Nous presenterons, dans cet article, les concepts theoriques de la therapie d’ACT et du Mindfluness, illustres d’exemples cliniques, mais e…

Synthesis, Stability and Relaxivity of TEEPO-Met: An Organic Radical as a Potential Tumour Targeting Contrast Agent for Magnetic Resonance Imaging

2018

Cancer is a widespread and life-threatening disease and its early-stage diagnosis is vital. One of the most effective, non-invasive tools in medical diagnostics is magnetic resonance imaging (MRI) with the aid of contrast agents. Contrast agents that are currently in clinical use contain metals, causing some restrictions in their use. Also, these contrast agents are mainly non-specific without any tissue targeting capabilities. Subsequently, the interest has notably increased in the research of organic, metal-free contrast agents. This study presents a new, stable organic radical, TEEPO-Met, where a radical moiety 2,2,6,6-tetraethylpiperidinoxide (TEEPO) is attached to an amino acid, methio…

Der gegenwärtige Stand der Blutfiltration - Grundlagen und klinische Bedeutung von Leukozytendepletions- und Mikroaggregatfiltern bei der Bluttransfu…

1993

In this review the role of the latest generation of leukodepletion blood filters and the adverse reaction of leukocytes i.e. alloimmunisation, immunosuppression, nonhaemolytic febrile transfusion reaction, platelet refractoriness, transmission of infectious agents are described and discussed. Leukocyte-poor blood component is indicated for patients with a history of nonhaemolytic febrile transfusion reaction, in avoiding alloimmunisation in patients waiting for transplantation or platelet refractoriness and in preventing CMV-infection. In the review the role of microaggregate filters in transfusion complications, namely, nonhaemolytic febrile transfusion reaction, thrombocytopenia, adult re…

Lung density distribution in dynamic CT correlates with oxygenation in ventilated pigs with lavage ARDS † †This study contains parts of the doctoral …

2003

Background Fast dynamic computed tomography (dCT) has been used to assess regional dynamics of lung inflation and deflation processes. The aim of this study was to relate ventilation-induced changes in lung density distribution, as measured over several respiratory cycles by dCT, to oxygenation and shunt fraction in a lavage acute respiratory distress syndrome model. Methods Six anaesthetized pigs underwent pressure-constant ventilation (F I O2=1.0, inspiratory:expiratory ratio=1:1) before and after induction of lung damage by saline lavage. Mean airway pressure ( P a μ w μ ) was varied (8, 13, 18, 23, 28, 33, and 38 cm H2O) in random order. At each P a μ w μ level, dCT acquisitions were pe…

Temporal dynamics of lung aeration determined by dynamic CT in a porcine model of ARDS

2001

We used dynamic CT to identify two different time constants of lung aeration and their individual contribution to the total increase in cross-sectional lung area in healthy and experimentally damaged lungs. In five healthy pigs, inflation and deflation between 0 and 50 cm H2O was imposed during dynamic (250 ms/image) CT acquisition, and repeated after experimental lung injury by saline lavage. The fractional areas of density ranges, which represent aerated lung parenchyma, were determined planimetrically, and their time for expansion during the manoeuvre was fitted using a bi-exponential model. Thus, two compartments, their sizes, i.e. their relative contributions to lung area aerated by th…
