Benefits on cognition from docosahexaenoic acid (DHA, 22 : 6 n-3) intake are absent in humans carrying apolipoprotein E ε4 allele (APOE4), the most important genetic risk factor for Alzheimer's disease (AD). To test the hypothesis that carrying APOE4 impairs DHA distribution, we evaluated plasma and brain fatty acid profiles and uptake of [(14) C]-DHA using(More)
Carrying the apoE ε4 allele (E4+ ) is the most important genetic risk for Alzheimer’s disease. Unlike non-carriers (E4- ), E4+ seem not to be protected against Alzheimer's disease when consuming fish. We hypothesised that this may be linked to a disturbance in n-3 DHA metabolism in E4+. The aim of the present study was to evaluate [13C]DHA metabolism over(More)
BACKGROUND Docosahexaenoic acid (DHA) kinetics appear to change with intake, which is an effect that we studied in an older population by using uniformly carbon-13-labeled DHA ((13)C-DHA). OBJECTIVE We evaluated the influence of a fish-oil supplement over 5 mo on the kinetics of (13)C-DHA in older persons. DESIGN Thirty-four healthy, cognitively normal(More)
Optimizing heath care services for seniors in emergency departments (ED) is a core component of the “Senior Friendly Hospital Approach” being implemented in Quebec. We measured the availability of geriatric expertise in Quebec EDs and its relationship with ED characteristics such as university affiliation, number of stretchers, and geographical location. We(More)
