Obese Veterans Enrolled in a Veterans Affairs Medical Center Outpatient Weight Loss Clinic Are Likely to Experience Disordered Sleep and Posttraumatic Stress.

Study Objectives: This cross-sectional study aimed to characterize sleep patterns, the quality and duration of sleep, and estimate the prevalence of common sleep disorders and posttraumatic stress disorder (PTSD) in a hospital-based Veterans Affairs MOVE! (Managing Overweight Veterans Everywhere) clinic.

Methods: Participants completed five instruments: the Pittsburgh Sleep Quality Index (PSQI), Smith's Measure of Morningness/Eveningness, Restless Legs Syndrome Rating Scale, the STOP Questionnaire, and the Posttraumatic Stress Disorder (PTSD) Checklist - Civilian Version (PCL-C).

Results: Enrolled Veterans (n = 96) were mostly male (78%), African American (49%), mean age 58 (standard deviation [SD] 10.

Effects of obstructive sleep apnea on sleep quality, cognition, and driving performance in patients with cirrhosis.

Background & Aims: In patients with cirrhosis, sleep disturbances are assumed to result from hepatic encephalopathy (HE). The effects of obstructive sleep apnea (OSA) on cognition, sleep parameters, or driving in patients with cirrhosis are unclear.

Methods: We performed a cross-sectional and prospective study of 118 subjects.

Effect of obstructive sleep apnea on the sleep architecture in cirrhosis.

Study Objectives: Sleep disturbances in cirrhosis are assumed to be due to hepatic encephalopathy (HE). The interaction between cirrhosis, prior HE, and obstructive sleep apnea (OSA) has not been evaluated. We aimed to evaluate the additional effect of cirrhosis with and without prior HE on the sleep architecture and perceived sleep disturbances of OSA patients.
