Randomized Controlled Trial
Free recall of word lists under total sleep deprivation and after recovery sleep.
One task that has been used to assess memory effects of prior total sleep deprivation (TSD) is the immediate free recall of word lists; however, results have been mixed. A possible explanation for this is task impurity, since recall of words from different serial positions reflects use of distinct types of memory (last words: short-term memory; first and intermediate words: episodic memory). Here we studied the effects of 2 nights of TSD on immediate free recall of semantically unrelated word lists considering the serial position curve. ⋯ Prior TSD spared episodic memory, short-term phonological memory, and interference, allowed the development of recall strategies, but may have decreased the advantage of using these strategies, which returned to normal after recovery sleep.

Randomized Controlled Trial
The effect of exercise training on obstructive sleep apnea and sleep quality: a randomized controlled trial.
To evaluate the efficacy of a 12-week exercise training program for reducing obstructive sleep apnea (OSA) severity and improving sleep quality, and to explore possible mechanisms by which exercise may reduce OSA severity. ⋯ Exercise training had moderate treatment efficacy for the reduction of AHI in sedentary overweight/obese adults, which suggests that exercise may be beneficial for the management of OSA beyond simply facilitating weight loss.

Randomized Controlled Trial Multicenter Study
The performance of two automatic servo-ventilation devices in the treatment of central sleep apnea.
This study was conducted to evaluate the therapeutic performance of a new auto Servo Ventilation device (Philips Respironics autoSV Advanced) for the treatment of complex central sleep apnea (CompSA). The features of autoSV Advanced include an automatic expiratory pressure (EPAP) adjustment, an advanced algorithm for distinguishing open versus obstructed airway apnea, a modified auto backup rate which is proportional to subject's baseline breathing rate, and a variable inspiratory support. Our primary aim was to compare the performance of the advanced servo-ventilator (BiPAP autoSV Advanced) with conventional servo-ventilator (BiPAP autoSV) in treating central sleep apnea (CSA). ⋯ BiPAP autoSV Advanced was more effective than conventional BiPAP autoSV in the treatment of sleep disordered breathing in patients with CSA.

Randomized Controlled Trial Multicenter Study
Race and residential socioeconomics as predictors of CPAP adherence.
There are few established predictors of CPAP adherence; poor adherence limits its effectiveness. We investigated whether race, education level, and residential economic status predict CPAP adherence in participants enrolled in a trial with standard access to treatment. ⋯ Black race and lower socioeconomic residential areas are associated with poorer adherence to CPAP in subjects with standardized access to care and treatment. Disparities remain despite provision of standardized care in a clinical trial setting. Future research is needed to identify barriers to adherence and to develop interventions tailored to improve CPAP adherence in at risk populations.
