Randomized Controlled Trial Clinical Trial
The nursing home at night: effects of an intervention on noise, light, and sleep.
The sleep of nursing home residents is fragmented by frequent awakening episodes associated, at least in part, with environmental variables, including noise and light changes. The purpose of this study was to improve sleep by reducing the frequency of nighttime noise and light changes. ⋯ The significant reductions in noise and light events resulting from the intervention did not lead to significant improvements in the day sleep and most night sleep measures. An intervention that combines both behavioral and environmental strategies and that addresses daytime behavioral factors associated with poor sleep (e.g., excessive time in bed) would potentially be more effective in improving the night sleep and quality of life of nursing home residents.

To examine the presence or absence of dementia, and the prevalence rates for different dementias, in patients with and without adult onset diabetes (AODM). ⋯ In our study, AD diagnosed clinically and AODM did not co-occur, whereas AODM was associated with vascular dementia diagnosed clinically. Conversely, in non-Alzheimer, nonvascular dementias diagnosed clinically, the rates of AODM were equivalent to those in nondemented patients. These findings are in agreement with some, but not all, previous studies.
