Amyloid imaging results from the Australian Imaging, Biomarkers and Lifestyle (AIBL) study of aging.

The Australian Imaging, Biomarkers and Lifestyle (AIBL) study of aging, a participant of the worldwide Alzheimer's Disease Neuroimaging Initiative (ADNI), performed (11)C-Pittsburgh Compound B (PiB) scans in 177 healthy controls (HC), 57 mild cognitive impairment (MCI) subjects, and 53 mild Alzheimer's disease (AD) patients. High PiB binding was present in 33% of HC (49% in ApoE-epsilon4 carriers vs 21% in noncarriers) and increased with age, most strongly in epsilon4 carriers. 18% of HC aged 60-69 had high PiB binding rising to 65% in those over 80 years.

Estimating population-based injury prevention practices.

This study piloted a survey suitable to generate statewide prevalence estimates for injury prevention practices and/or behaviours. A number of prevalence estimates of injury prevention practices and/or behaviours were generated in the pilot. For example, the prevalence of a household smoke alarm was high (732/1000 households) and yet only 44% of households had tested the functionality of the alarm in the 12 months preceding the survey.

Childhood drowning: barriers surrounding private swimming pools.

Objective: To investigate the causes of child drowning and determine the need for changes in the legislation as well as improvements to the inspection and enforcement of current legislation related to barriers surrounding private swimming pools.

Methods: There were 3 stages to the study: a retrospective review of coroner's data, an audit of swimming pool inspections, and in-depth interviews with swimming pool inspectors in Western Australia. The incidence of childhood drowning (per population) and compliance rates of swimming pools (per 1000 swimming pools) to the legislation were measured.
