Potentially inappropriate medication use among patients with Alzheimer disease in the REAL.FR cohort: be aware of atropinic and benzodiazepine drugs!

Abstract Objective Few studies have investigated potentially inappropriate medication (PIM) use in patients with Alzheimer's disease (AD). The aim of our study was to assess the prevalence of PIM in community-dwelling patients diagnosed with mild-to-moderate AD and identify the clinical factors associated with PIM prescriptions. Methods REAL.FR is a 4-year, prospective, multicenter French cohort of AD patients recruited in centers of expertise. We analyzed patient baseline data at entry into the study. PIMs were assessed using the Laroche list. A multivariate logistic regression was conducted to assess factors associated with PIMs. Results A total of 684 AD patients were enrolled in the study [mean age 77.9±6.8 years, 486 (71.0 %) females]. According to the Laroche list, 46.8 % [95 % confidence interval (CI) 43.0-50.5 %] of the patients had at least one PIM. "Cerebral vasodilators" were the most widely used class of PIM, accounting for 24.0 % (95 % CI 20.9-27.3 %) of all prescriptions, followed by atropinic drugs (17.0 %, 95 % CI 14.1-19.8 %) and long half-life benzodiazepines (8.5 %, 95 % CI 6.4-10.6 %). Atropinic drugs were associated with cholinesterase inhibitors in 16 % of patients. In the multivariate analysis, only two factors, namely, female gender [odds ratio (OR) 1.5, 95 % CI 1.1-2.2] and polypharmacy (≥5 drugs; OR3.6, 95 % CI 2.6-4.5) were associated with prescriptions for PIMs. Conclusions These results reveal that approximately one out of two community-dwelling patients with mild-to-moderate AD treated by AD specialists use PIMs. They also indicate that the characteristics of the disease and the pharmacodynamic/ pharmacokinetic profile of the drugs prescribed are not sufficiently taken into account by physicians when prescribing for AD patients

Buprénorphine haut dosage en médecine ambulatoire (comparaison des modes d'utilisation en Haute-Garonne entre 2000 et 2005)

La buprénorphine haut dosage (BHD) pose des problèmes de trafic et de mésusage. Un plan d'action national de l'Assurance Maladie a été instauré en 2004 pour limiter ces phénomènes. L'objectif de ce travail était de mesurer l'impact de cette mesure sur l'usage rationnel. A partir des données de l'Assurance Maladie, nous avons comparé les nouveaux substitués par BHD en 2000 et 2005. Alors que la proportion d'usagers rationnels de BHD est restée stable, on observe une augmentation de la proportion des consommateurs excessifs et nomades parmi les usagers non rationnels . Enfin, l'exposition aux benzodiazépines n'a pas diminué : si l'exposition au flunitrazépam et au clorazépate 50 mg a diminué, on peut suspecter un détournement d'usage du clonazépam et du bromazépam. Malgré les diverses mesures entreprises, une attention accrue reste recommandée lors de l'instauration de la BHD.TOULOUSE3-BU Santé-Centrale (315552105) / SudocPARIS-BIUM (751062103) / SudocSudocFranceF

Healthcare use according to deprivation among French Alzheimer's Disease and Related Diseases subjects: a national cross-sectional descriptive study based on the FRA-DEM cohort

IntroductionPluriprofessional and coordinated healthcare use is recommended for Alzheimer's Disease and Related Diseases (ADRD). Despite a protective health system, France is characterized by persistent and significant social inequalities in health. Although social health inequalities are well documented, less is known about social disparities in healthcare use in ADRD, especially in France. Therefore, this study aimed to describe healthcare use according to socioeconomic deprivation among ADRD subjects and the possible potentiating role of deprivation by age.MethodsWe studied subjects identified with incident ADRD in 2017 in the French health insurance database (SNDS). We described a large extent of their healthcare use during the year following their ADRD identification. Deprivation was assessed through French deprivation index (Fdep), measured at the municipality level, and categorized into quintiles. We compared healthcare use according to the Fdep quintiles through chi-square tests. We stratified the description of certain healthcare uses by age groups (40–64 years, 65–74 years, 75–84 years, 85 years, and older), number of comorbidities (0, 1, 2–3, 4 comorbidities and more), or the presence of psychiatric comorbidity.ResultsIn total, 124,441 subjects were included. The most deprived subjects had less use of physiotherapy (28.56% vs. 38.24%), ambulatory specialists (27.24% vs. 34.07%), ambulatory speech therapy (6.35% vs. 16.64%), preventive consultations (62.34% vs. 69.65%), and were less institutionalized (28.09% vs. 31.33%) than the less deprived ones. Conversely, they were more exposed to antipsychotics (11.16% vs. 8.43%), benzodiazepines (24.34% vs. 19.07%), hospital emergency care (63.84% vs. 57.57%), and potentially avoidable hospitalizations (12.04% vs. 10.95%) than the less deprived ones.Discussion and conclusionThe healthcare use of subjects with ADRD in France differed according to the deprivation index, suggesting potential health renunciation as in other diseases. These social inequalities may be driven by financial barriers and lower education levels, which contribute to health literacy (especially for preventive care). Further studies may explore them

Calcineurin regulation of cytoskeleton organization: a new paradigm to analyse the effects of calcineurin inhibitors on the kidney.

International audienceCalcineurin is a serine/threonine phosphatase originally involved in the immune response but is also known for its role as a central mediator in various non-immunological intracellular signals. The nuclear factor of activated T cell (NFAT) proteins are the most widely described substrates of calcineurin, but ongoing work has uncovered other substrates among which are the cytoskeleton organizing proteins (i.e. cofilin, synaptopodin, WAVE-1). Control over cytoskeletal proteins is of outmost interest because the phenotypic properties of cells are dependent on cytoskeleton architecture integrity, while rearrangements of the cytoskeleton are implicated in both physiological and pathological processes. Previous works investigating the role of calcineurin on the cytoskeleton have focused on neurite elongation, myocyte hypertrophic response and recently in kidney cells structure. Nuclear factor of activated T cell activation is expectedly identified in the signalling pathways for calcineurin-induced cytoskeleton organization, however new NFAT-independent pathways have also been uncovered. The aim of this review is to summarize the current knowledge on the effects of calcineurin on cytoskeletal proteins and related intracellular pathways. These newly described properties of calcineurin on cytoskeletal proteins may explain some of the beneficial or deleterious effects observed in kidney cells associated with the use of the calcineurin inhibitors, cyclosporine and tacrolimus

Virtual Reality and Physical Activity: Attentional and Behavioral Aspects

International audienceThe present study tested the effects of sensorial inputs on performance and attentional focus during physical training on a computerized ergometer. 18 students were involved in this study. The experimental procedure consisted in a 3x3x4 mixed design, with 3 practice modalities (virtual feedback, virtual feedback and music, virtual and heart rate feedback) 3 course phases (e.g., flat, uphill, downhill) and 4 sessions. The virtual feedback was a video film of the course subjects had to complete. Video display speed was proportional to the subject's pedalling speed. Results show a training effect on the subjects' overall performance and a reduction of the time spent gazing at video feedback across sessions. The results are discussed in terms of the functional status of sensorial stimulation and its interactions with exercise intensity and subject performance
