[Morpheus syndrome: Psychotic symptoms in a case series of patients with COVID-19]. / Le syndrome de Morpheus : symptômes psychotiques chez une série de cas de patients atteints de la COVID-19.

During the first wave of the COVID-19 epidemic, the Colmar hospital was at the epicenter of the pandemic in France because of a religious gathering that caused a wave of contamination. In order to face the growing wave of admissions in intensive care, the state in partnership with the army set up the operation MORPHEE aiming at transferring intubated patients to other hospitals. On their return to Alsace, the inter-service liaison psychiatry team was called upon for several of them who presented psychotic disorders on waking up, even though they had no previous psychiatric history, and who had resolved spontaneously. These pictures do not correspond to the delirious pictures usually observed in the ICU, such as "reanimatory black-holes" or "near-death-experience". No iatrogenic origin was found and the imaging examinations do not allow to explain this picture; therefore, we cannot exclude that this picture could be a neurological manifestation of COVID-19. The disorder appeared to be spontaneously resolving, so we would urge caution about a drug approach to this problem.

[Do liquid wastes from automated instruments in medical laboratories have their proper microbicide effect?] / Les rejets liquides des automates de biologie médicale ont-ils un effet microbicide propre qui permettrait de s'affranchir de leur traitement pour risque infectieux ?

Liquid wastes from clinical biology automated systems are currently evacuated in the urban network after chemical treatment to eliminate a possible risk of infection. Since these wastes are ecotoxic because of the presence of numerous chemical reagents, we studied their intrinsic microbicidal power towards a selection of infectious agents widely found in clinical specimens. The objective was to determine if an additional anti-infectious treatment before elimination is necessary. Thus, we evaluated the bactericidal effect of liquid wastes of several automated systems towards four bacterial species (Escherichia coli, Staphylococcus aureus, Pseudomonas aeruginosa and Enterococcus faecalis) and their virucidal activity against a non-enveloped virus, resistant in the environment (adenovirus). This effect was determined for different exposure times. Our results showed that the antibacterial activity was highly variable depending on the waste-bacteria pair considered (varying from no activity to complete sterilization of a strong bacterial inoculum). The liquid wastes were on the other hand globally inactive towards adenovirus.

Service dogs in the province of Quebec: sociodemographic profile of users and the dogs' impact on functional ability.

PURPOSE: The objectives of this study were to (1) describe the sociodemographic profile of service dog users, their physical disabilities, main occupations, living environment, and use of technical aids in daily life and (2) evaluate the impact of service dogs on wheelchair travel and picking up objects. METHOD: Sociodemographic and clinical data were collected and various mobility tests were conducted in the service dog users' home environment (n = 199). RESULTS: The service dog users had injuries to the central or peripheral nervous system (55%), spinal cord (33%), or musculoskeletal or orthopedic system (12%). In the wheelchair travel on flat terrain test (n = 67), users travelled a longer distance in a shorter time, improving their average speed to 1.28 m/s with the service dog compared to 0.75 m/s without (p < 0.001). In a wheelchair propelling up a slope, 42% improved with the service dog (n = 60). Mounting a threshold/curb in a wheelchair, 41% improved with the service dog (n = 39). In a test where walkers and wheelchair users picked up three objects off the ground, 44% improved with the service dog (n = 164). CONCLUSION: Service dogs significantly improved wheelchair travel speed and distance on flat and ascending terrain, mounting a threshold/curb and picking up objects off the ground. Implications for Rehabilitation For people with motor impairments: Service dogs are most often used as a technical aid to pick up objects (96%), open doors (36%) and pull the wheelchair during travel (34%). Clients' performance in significant travel in a wheelchair (on flat terrain, on an upslope, mounting a threshold) improved with the service dog compared to their own performance without the dog. Clients' grasping performance (picking up three significant objects off the ground) improved with the service dog compared to their own performance without the dog.

Effects of a mobility assistance dog on the performance of functional mobility tests among ambulatory individuals with physical impairments and functional disabilities.

This study aims to verify whether individuals with physical impairments and ambulatory disabilities perform functional mobility tests faster using an assistance dog for mobility (AD(Mob)). Thirty-four individuals with various physical impairments and functional disabilities performed at least one of the four functional mobility tests within their natural environment during an in-home assessment. Participants randomly performed the 10-meter walk test, the timed up-and-go (TUG) test, and the stair ascent and descent tests with and without an AD(Mob) during an in-home assessment. The main outcome measure was the time needed to complete all tests with and without an AD(Mob). When using an AD(Mob), many participants (> or = 70.4%) were faster when performing the 10-meter walk test (15.7 +/- 8.5s vs. 19.1 +/- 11.2s), TUG test (23.6 +/- 14.2s vs. 27.3 +/- 16.5s), and stair ascent test (18.6 +/- 13.5s vs. 22.4 +/- 17.5s) compared to doing the tests without an AD(Mob). As for the stair descent test, the use of the AD(Mob) had no significant effect on performance (20.7 +/- 15.9s vs. 24.0 +/- 17.1s). When using an AD(Mob), the majority of individuals with physical impairments and functional disabilities significantly improved their performance (i.e., reduced their time) during the 10-meter walk test, the TUG test and the stair ascent test.
