BACKGROUND Whether hearing loss is independently associated with accelerated cognitive decline in older adults is unknown. METHODS We studied 1984 older adults (mean age, 77.4 years) enrolled in the Health ABC Study, a prospective observational study begun in 1997-1998. Our baseline cohort consisted of participants without prevalent cognitive impairment (Modified Mini-Mental State Examination [...
CONTEXT Lower plasma β-amyloid 42 and 42/40 levels have been associated with incident dementia, but results are conflicting and few have investigated cognitive decline among elders without dementia. OBJECTIVE To determine if plasma β-amyloid is associated with cognitive decline and if this association is modified by measures of cognitive reserve. DESIGN, SETTING, AND PARTICIPANTS We studied...
OBJECTIVE Patients with dementia benefit from early assessment and diagnosis. In an attempt to identify factors leading to delay in referral, we investigated socio-demographic, clinical, and functional predictors of greater severity of cognitive impairment in dementia patients presenting to a memory clinic in Saskatoon, Saskatchewan. METHODS Data collection began in 2004 at the Rural and Remo...
The formation of supercavitation after a high-speed projectile enters water has decisive impact on the underwater ballistic and penetration projectile. In this study, Ansysfluent19.0 simulation software is used to study entry chosen at velocities 300, 400, 500, 600 m/s. cavitation characteristics, trajectories, flow-field characteristics are analyzed for 5.8-mm caliber conical flat head project...
Coastal wetlands are considered as important “blue carbon” sink, and mowing management induced by anthropogenic activities is anticipated to profoundly affect soil carbon stocks in coastal wetlands. However, the impacts of on organic (SOC) enzyme mechanisms responsible for associated changes Phragmites australis wetland remain uncertain. We conducted a field manipulation experiment [control (CK...
background: the patterns of facial growth, jaw and tooth size are inherited and are likely to differ among population and races. aim of this study is to evaluate and compare the pattern of third molar (3m) impaction among three different ethnic groups (chinese, indian, malay) of patients attending aimst dental institute, malaysia. materials and methods: dental records and orthopantomographs of ...
As the number of older adults undergoing hemodialysis increases, it is important for nurses to consider cognitive impairment as a contributing factor to non-adherence. The purpose of this exploratory study was to identify cognitive markers that nurses can use to alert them to potential problems with adherence among older adults undergoing hemodialysis. Stories of the health challenge of making ...
Methods: In 1991, 1763 community-dwelling adults aged 65+ participated in the Manitoba Study of Health and Aging (MSHA), which sampled all regions of the province of Manitoba. Baseline measures included age, gender, years of education, the Modified Mini-Mental State Examination (3MS), and rural/urban status. Rural was defined as a census subdivision with a population <20,000 and urban as 20,000...
Mitochondrial DNA sequence variation associated with dementia and cognitive function in the elderly.
Mitochondrial dysfunction is a prominent hallmark of Alzheimer's disease (AD). Mitochondrial DNA (mtDNA) damage may be a major cause of abnormal reactive oxidative species production in AD or increased neuronal susceptibility to oxidative injury during aging. The purpose of this study was to assess the influence of mtDNA sequence variation on clinically significant cognitive impairment and deme...
