Preoperative pain neuroscience education combined with knee joint mobilization for knee osteoarthritis : a randomized controlled trial
2017
Abstract: Objectives: This study aimed to first compare the effects of a preoperative treatment combining pain neuroscience education (PNE) with knee joint mobilization versus biomedical education with knee joint mobilization on central sensitization (CS) in patients with knee osteoarthritis, both before and after surgery. Second, we wanted to compare the effects of both interventions on knee pain, disability, and psychosocial variables. Materials and Methods: Forty-four patients with knee osteoarthritis were allocated to receive 4 sessions of either PNE combined with knee joint mobilization or biomedical education with knee joint mobilization before surgery. All participants completed self…
Design considerations of a randomized clinical trial on a cognitive behavioural intervention using communication and information technologies for man…
2013
Background Psychological treatments have been successful in treating chronic low back pain (CLBP). However, the effect sizes are still modest and there is room for improvement. A way to progress is by enhancing treatment adherence and self-management using information and communication technologies (ICTs). Therefore, the objective of this study was to design a trial investigating the short- and long-term efficacy of cognitive behavioural treatment (CBT) for CLBP using or not ICTs. A secondary objective of this trial will be to evaluate the influence of relevant variables on treatment response. Possible barriers in the implementation of CBT with and without ICT will also be investigated. Met…
Neural Correlates of Deficits in Pain-Related Affective Meaning Construction in Patients With Chronic Pain Disorder
2013
OBJECTIVE Psychological and neural mechanisms of the affective dimension of pain are known to be disturbed in patients with chronic pain disorder. The aim of this functional magnetic resonance imaging study was to assess the neurofunctional and behavioral measures underlying the ability to construct pain-related affective meaning in a painful situation by comparing 21 clinically and psychometrically well-characterized patients with persistent non-nociceptive somatoform pain with 19 healthy controls. METHODS The functional magnetic resonance imaging task involved viewing pictures depicting human hands and feet in different painful and nonpainful situations. Participants were asked to estimat…
Risk factors for depression and anxiety in painful and painless diabetic polyneuropathy: A multicentre observational cross‐sectional study
2021
BACKGROUND Despite the high prevalence of depression and anxiety in chronic pain conditions, current knowledge concerning emotional distress among painful diabetic polyneuropathy (pDSPN) and other diabetes mellitus (DM) sufferers is limited. METHODS This observational multicentre cohort study employed the Hospital Anxiety and Depression Scale, the Beck Depression Inventory II and the State-Trait Anxiety Inventory to assess symptoms of depression and anxiety in several groups with diabetes, as well as in a control group. The study cohort included 347 pDSPN patients aged 63.4 years (median), 55.9% males; 311 pain-free diabetic polyneuropathy (nDSPN) patients aged 63.7 years, 57.9% males; 50 d…
Catastrophic risks and the pricing of catastrophe equity put options
2021
In this paper, after a review of the most common financial strategies and products that insurance companies use to hedge catastrophic risks, we study an option pricing model based on processes with jumps where the catastrophic event is captured by a compound Poisson process with negative jumps. Given the importance that catastrophe equity put options (CatEPuts) have in this context, we introduce a pricing approach that provides not only a theoretical contribution whose applicability remains confined to purely numerical examples and experiments, but which can be implemented starting from real data and applied to the evaluation of real CatEPuts. We propose a calibration framework based on his…
Pressure stability field of Mg-perovskite under deep mantle conditions: A topological approach based on Bader's analysis coupled with catastrophe the…
2019
Abstract The pressure stability field of the Mg-perovskite phase was investigated by characterizing the evolution of the electron arrangement in the crystal. Ab initio calculations of the perovskite structures in the range 0–185 GPa were performed at the HF/DFT (Hartree-Fock/Density Functional Theory) exchange–correlation terms level. The electron densities, calculated throughout the ab-initio wave functions, were analysed by means of the Bader's theory, coupled with Thom's catastrophe theory. To the best of our knowledge the approach is used for the first time. The topological results show the occurrence of two topological anomalies at P~20 GPa and P~110 GPa which delineate the pressure ra…

Abstract The fatigue life of thermally sprayed Al2O3- and Cr2O3-based coatings has been studied under low-energy (0.7–5 mJ) impact conditions. A threshold impact energy and amount of repetitions the coatings can endure with said energy before catastrophic failure was obtained. The catastrophic failure was determined to occur when the fracture mode of the coating switched from brittle cone cracking to quasi-plastic radial cracking. The results are examined relative to the microstructural features along with other properties of the coatings - hardness and cavitation resistance. The experiment provided a new approach for a straightforward comparison of the micro-scale impact fatigue life of th…
Les catastrophes naturelles au Moyen Âge (XIIe-XVe siècle)
2017
International audience; Catastrophe : le terme renvoie dans nos représentations contemporaines à des images de destruction, de désorganisation sociale et éventuellement de mort de masse. Les événements tels que les inondations, les tremblements de terre, les tempêtes, etc., sont inévitablement pensés sur le mode du drame et de la tragédie. Viennent à l'esprit la nécessité de comprendre l'événement à travers un bilan des pertes matérielles et surtout humaines, la détresse des populations sinistrées, le devoir gouvernemental et non-gouvernemental de développer l'aide humanitaire, et le nécessaire travail de mémoire d'un malheur collectif. C’est en considérant ce faisceau de réaction en tant q…
