This study investigated everyday associations between one key facet of mindfulness (allocating attention to the present moment) and pain. In Study 1, 89 community-dwelling adults (33–88 years; Mage = 68.6) who had experienced a stroke provided 14 daily end-of-day present-moment awareness and pain ratings. In Study 2, 100 adults (50–85 years; Mage = 67.0 years) provided momentary present-moment awareness and pain ratings three times daily for 10 days. Multi-level models showed that higher trait present-moment awareness was linked with lower overall pain (both studies). In Study 1, participants reported less pain on days on which they indicated higher present-moment awareness. In Study 2, only individuals with no post-secondary education reported less pain in moments when they indicated higher present-moment awareness. Findings add to previous research using global retrospective pain measures by showing that present-moment awareness might correlate with reduced pain experiences, assessed close in time to when they occur.

This paper provides a solution to the active vibration control of a microsatellite with two solar panels. At first, the microsatellite is processed as a finite element model containing a rigid body and two flexible bodies, according to the principles of mechanics, and that the dynamic characteristics are solved by modal analysis. Secondly, the equation involving vibration control is established according to the finite element calculation results. There are several actuators composed of macro fibre composite on the two solar panels for outputting control force. Furthermore, the control voltage for driving actuator is calculated by using fuzzy algorithm. It is clear that the smart structure consists of the flexible bodies and actuators. Finally, the closed-loop control simulation for suppressing harmful vibration is established. The simulation results illustrate that the responses to the external excitation are decreased significantly after adopting fuzzy control.

La stratégie à adopter face à un EDM au décours d’un AVC est délicate. Bien qu’ayant un effet positif sur la récupération fonctionnelle après un AVC, les antidépresseurs IRS risquent d’induire des effets indésirables hémorragiques, notamment cutanéomuqueux et digestifs. Ils pourraient donc majorer le risque d’AVC hémorragique chez les patients les plus fragiles. Les antidépresseurs IRSNa pourraient intervenir à différents niveaux pour majorer ce risque. Cette problématique sera illustrée à travers un cas clinique. Puis, nous détaillerons les mécanismes biologiques impliqués, particulièrement l’inhibition des voies concourant à la formation du caillot. La venlafaxine, par son activité dopaminergique, concourt de façon plus importante à ce risque en majorant la tension artérielle. Dans ce contexte, il paraît nécessaire d’être particulièrement vigilant dans la prescription d’IRS et d’IRSNa chez les populations à risque de saignements et en cas d’interactions potentielles avec un traitement intervenant sur l’hémostase (AINS, antiagrégants plaquettaires, anticoagulants…). L’usage d’autres classes thérapeutiques d’antidépresseur constitue une alternative intéressante.
