Translating cognitive neuroscience to fitness to drive using a neuroergonomic approach

Non-pathological or normal ageing is accompanied by brain alterations that are the result of natural changes occurring with age and our ability to compensate for them. Compared to younger adults, older adults have reduced vision, more difficulties in detecting relevant information they are not intending to and require more time to process sensorial information. Little is known on how these changes affect behaviour in a natural environment. Relying on a translational approach at the frontiers between neurobiology, psychophysics, neuropsychology and epidemiology, we were able to: explore the needs for innovative instrumentations to detect cerebral decline in clinical settings; develop and validate a new computed neuropsychological instrument designed to measure cerebral decline in healthy older adults; explore the link between processing speed and on-road driving performance; and investigate the effects of being able to anticipate on visual processing speed.

Neurorééducation précoce au Centre hospitalier universitaire vaudois: du rêve à la réalité [Early neurorehabilitation in an acute university hospital: from dream to reality].

The need for an early neurorehabilitation pathway was identified in an acute university hospital. A team was formed to draw up and implement it. A neuro-sensorial, interdisciplinary and coordinated therapy program was developed, focused on tracheostomised patients as soon as they were admitted to the intermediate care in neurology and neurosurgery. The impact of this care plan was evaluated by comparing the results obtained with that pertaining to patients treated previously in the same services. The comparison showed a reduction of 48% of the mean duration of tracheostomy, of 39% in the time to inscription in a neurorehabilitation centre and of 20% in the length of stay in the intermediate care. An early neurorehabilitation care program, with an interdisciplinary and coordinated team, reduces complications and lengths of stay.

Enhanced kangaroo mother care for heel lance in preterm neonates: a crossover trial.

OBJECTIVE: To test if enhancing maternal skin-to-skin contact, or kangaroo mother care (KMC) by adding rocking, singing and sucking is more efficacious than simple KMC for procedural pain in preterm neonates. STUDY DESIGN: Preterm neonates (n=90) between 32 0/7 and 36 0/7 weeks' gestational age participated in a single-blind randomized crossover design. The infant was held in KMC with the addition of rocking, singing and sucking or the infant was held in KMC without additional stimulation. The Premature Infant Pain Profile was the primary outcome with time to recover as the secondary outcome. A repeated-measures analysis of covariance was employed for analyses. RESULT: There were no significant differences in any of the 30 s time periods over the 2 min of blood sampling nor in time to return to baseline. Compared to historical controls of the same age in incubator, the pain scores were lower and comparable to other studies of KMC. There were site differences related to lower scores with the use of sucrose in one site and higher scores in younger, sicker infants in another site. CONCLUSION: The sensorial stimulations from skin-to-skin contact that include tactile, olfactory sensations from the mother are sufficient to decrease pain response in premature neonates. Other studies showing that rocking, sucking and music were efficacious were independent of skin-to-skin contact, which, when used alone has been shown to be effective as reported across studies.

Lorsque les électrosensibles racontent : des douleurs chroniques aux pratiques d'auto-éviction

Résumé : Cet article propose une analyse du vécu de personnes électrosensibles et de la façon dont ils ont répondu aux douleurs chroniques. L'approche proposée vise à relater les stratégies de réponse à ces formes de morbidité en valorisant les récits des protagonistes ; plus particulièrement, l'accent est mis sur les dimensions cognitives, sensorielles, émotionnelles, relationnelles et existentielles engendrées par une symptomatologie qui ne correspond à aucune explication scientifique causale. Leurs récits mettent ainsi en perspective des trajectoires de vie avec les conditions sociales, médicales et somatiques dans lesquelles est menée leur quête de santé. Mettre l'accent sur les expériences quotidiennes qui fondent la représentation que les électrosensibles ont de leurs troubles permet de comprendre les raisons et les modalités des formes d'auto-éviction qu'ils pratiquent. La réalisation des modalités de l'auto-éviction sont alors interprétées comme l'aboutissement d'une trajectoire de vie, produit de choix intuitifs - et non stratégiques - basés sur des sensibilités singulières. Il en résulte un regard anthropologique invitant à interpréter l'expérience des douleurs chroniques au prisme des rapports sensibles que les individus entretiennent avec leur corps, les autres et l'environnement. Abstract: This paper analyses the lived experience of electrosensitive people and the way they reply to chronic pain. The approach aims to relate the way they reply to this kind of morbidity by highlighting their narratives; especially by emphasising the cognitive, the sensorial, the emotional, the relational and the existential dimensions produced by a symptomatology that is not scientifically explained. Their narratives put into perspective their life trajectories with the social, medical and somatic conditions that lead their health quest. Focusing on the ordinary, that shapes the representations the electrosensitive people have of their troubles, would allow us to understand the reasons and modalities of auto-eviction practices. Auto-eviction achievement is interpreted as a life trajectory fulfilment produced by intuitive choices - nonstrategic - based on singular sensitivities. As a result, it invites an anthropological interpretation of chronic pain experiences built on the sensitive relationships that individuals have with their body, the others and the environment.
