In rats, c-FOS positive (i.e. “active”) orexinergic neurons were reduced during propofol anesthesia, and restored during emergence. Microinjection of orexin-A into the basal forebrain caused a reduction in burst suppression ratio on EEG, and reduced time to emergence from propofol anesthesia. These results suggest that activation of orexinergic signaling plays a role in emergence from propofol anesthesia.

This review summarizes the published literature on the links between elevations of pro-inflammatory cytokine IL-6 and sleep and vice-versa.

This work presents further evidence of the genetic component (expression of Ntsr1 gene) implicated in the regulation of both sleep and mood disorders.

This work illustrates the effect of sleep disruption in lung function and ventilation.

This study presents a very elegant work that shows a role for glycolytic processes in sleep homeostasis.

The rate of unplanned admission was 7.0% (95% confidence interval [CI] 5.1 to 8.9) in OSA patients compared with 5.6% (95% CI 4.1 to 7.1) in patients without OSA (odds ratio 1.26; 95% CI 0.83 to 1.91; P = 0.246). Median [interquartile range; IQR] hospital length of stay was 7 hr [IQR 5, 8] with OSA and 6 hr [IQR 5, 8] without OSA (P = 0.058). Severity of OSA was not associated with unplanned admission. They did not identify a clinically important increased rate of unplanned admission associated with a prior diagnosis of OSA.
