The study objective was to validate a semi-quantitative food frequency questionnaire (FFQ) specifically designed to measure dietary vitamin K intake. A 50-item FFQ was interviewer-administered and compared with data previously obtained from 5-day food records. Thirty-nine community-dwelling healthy men and women aged 65 to 85 years were recruited from the(More)
A population-based cohort study design was used to estimate persistence rate, re-initiation rate after discontinuation, and adherence level among incident users of oral antidiabetics (OADs), and to investigate predictors of non-persistence and non-adherence. Incident OAD users were identified using healthcare databases of residents covered by the public(More)
PURPOSE To study the association between malnutrition and aspiration pneumonia (AP) in patients from active geriatric units and describe patients who developed AP. METHODS Cases of AP were identified from archived medical charts of two active geriatric units between 2001 and 2007 (n=2238). The prevalence of neurologic disorders, dysphagia and malnutrition(More)
An increasing body of evidence points to a role for vitamin K in brain physiology through its participation in sphingolipid metabolism and biological activation of the vitamin K-dependent protein Gas6. One hypothesis is that vitamin K may also play a role in the pathogenesis of Alzheimer's disease. A recent study found that patients with early-stage(More)
OBJECTIVES To assess quality-of-care processes and to examine whether care processes are associated with short-term postdischarge outcomes in older vulnerable hospitalized patients. DESIGN Retrospective study. SETTING Forty-nine Geriatric Assessment Units. PARTICIPANTS Patients aged 65 and older who were admitted to a Geriatric Assessment Unit for a(More)
OBJECTIVES Increased dietary intake of vitamin K, a fat-soluble nutrient involved in brain health and function, has been associated with better cognitive performance in older adults. Our objective was to determine whether the dietary vitamin K intake was associated with the presence and severity of subjective memory complaint among older adults. STUDY(More)
Evidence is accumulating that vitamin K could have a role in cognition, especially in aging. Using data from the Québec Longitudinal Study on Nutrition and Successful Aging (NuAge), a cross-sectional analysis was conducted to examine the associations between vitamin K status, measured as serum phylloquinone concentrations, and performance in verbal and(More)
Elderly living in nursing homes and long-term care units are well-known to be vulnerable to dehydration. Insufficient water intake contributes to suboptimal hydration status and leads to decreased quality of life and global health status. Based on published studies, 32 to 96% of nursing home residents had insufficient water intake and more than 50% drank(More)
