[Circadian rhythm sleep disorders]

22 Sep 2009 BACKGROUND: Circadian rhythm sleep disorders often lead to sleepiness and insomnia. These disorders are characterized by a misalignment between the intrinsic circadian rhythm and the external social and physical environment. MATERIAL AND METHOD: ... Read more...

Discharge profiles of identified GABAergic in comparison to cholinergic and putative glutamatergic basal forebrain neurons across the sleep-wake cycle.

21 Sep 2009 Whereas basal forebrain (BF) cholinergic neurons are known to participate in processes of cortical activation during wake (W) and paradoxical sleep (PS or P, also called REM sleep), codistributed GABAergic neurons have been thought to participate in ... Read more...

Association of resident fatigue and distress with perceived medical errors.

21 Sep 2009 CONTEXT: Fatigue and distress have been separately shown to be associated with medical errors. The contribution of each factor when assessed simultaneously is unknown. OBJECTIVE: To determine the association of fatigue and distress with ... Read more...
