On the first day in the lab, during testing of sleep latency, some fell asleep before the technician had even left the room.
During the study period, 2149 participants were referred for diagnostic testing of sleep apnea.
A cohort of all patients aged ≥18 years referred between July 2005 and December 2007 for diagnostic testing of sleep apnea to the Foothills Medical Centre (FMC) Sleep Centre or community respiratory care companies within the Calgary Health Region (population ∼1.3 million) were identified.
In summary, we found that nocturnal hypoxia was associated with an increased risk of accelerated loss of kidney function in this population referred for diagnostic testing of sleep apnea, suggesting that surveillance of kidney function may be prudent in patients with sleep disordered breathing.
The MOS questionnaire tests six dimensions of sleep, including initiation, maintenance (e.g. staying asleep), quantity, adequacy, somnolence (e.g. drowsiness), and respiratory impairments (e.g. shortness of breath, snoring).
On this background, our finding that with forward testing of retrieval, sleep specifically enhanced memory for the 1st transition is compatible with previous observations showing that sleep enhances memory for weak associations [37].
For each variable tested, the effects of sleep deprivation depend on the design of the test conditions.
The design allows for: (1) the first test of a sleep intervention in this population; (2) the comparison of sequenced CBTi and CPT to attention control followed by CPT, and (3) assessing the roles of neuroendocrine function, inflammatory processes, and objective sleep markers in mediating treatment outcomes.
[ 3] Psychometric testing of this sleep scale has been conducted in ambulatory and hospitalized patient populations.
We ran a randomized cross-over design study under sleep-deprived and non-sleep-deprived driving conditions to test the effects of sleep restriction on real driving performance.
