TL;DR: It is suggested that the mere onset of sleep may initiate active processes of consolidation which – once triggered – remain effective even if sleep is terminated shortly thereafter.
Abstract: Summary
Various studies have demonstrated that a night of sleep has a beneficial effect on the retention of previously acquired declarative material. In two experiments, we addressed the question of whether this effect extends to daytime naps. In the first experiment we assessed free recall of a list of 30 words after a 60 min retention interval that was either filled with daytime napping or waking activity. Memory performance was significantly enhanced after napping as opposed to waking but was not correlated with time spent in slow wave sleep or total sleep time within the napping condition. The second experiment was designed to clarify the role of total sleep time and therefore included an additional third group, which was allowed to nap for no longer than 6 min on average. In comparing word recall after conditions of no napping (waking), short napping, and long napping, we found superior recall for both nap conditions in contrast to waking as well as for long naps in contrast to short naps. These results demonstrate that even an ultra short period of sleep is sufficient to enhance memory processing. We suggest that the mere onset of sleep may initiate active processes of consolidation which – once triggered – remain effective even if sleep is terminated shortly thereafter.

TL;DR: The absence of palatal CCC during DISE may predict therapeutic success with implanted UAS therapy, and DISE can be recommended as a patient selection tool for implantation of a UAS system to treat OSA.
Abstract: Study Objectives:To study the possible predictive value of drug-induced sleep endoscopy (DISE) in assessing therapeutic response to implanted upper airway stimulation (UAS) for obstructive sleep ap...

TL;DR: It is reported that a night of sleep increases both veridical and false recall in the Deese-Roediger-McDermott (DRM) paradigm, compared to an equivalent period of daytime wakefulness, and that under certain circumstances sleep can promote false memories over verdical ones, and SWS can be associated with impairment rather than facilitation of declarative memory consolidation.

TL;DR: The findings suggest that sleep disturbance exacerbates symptom severity in the majority of anxiety and related disorders, however, the nature of sleep disturbance often varies as a function of objective versus subjective assessment.

TL;DR: The findings indicate that REM OSA is cross-sectionally and longitudinally associated with hypertension, clinically relevant because treatment of OSA was often limited to the first half of the sleep period leaving most of REM sleep untreated.
Abstract: Rationale: Obstructive sleep apnea (OSA) is associated with hypertension.Objectives: We aimed to quantify the independent association of OSA during REM sleep with prevalent and incident hypertension.Methods: We included adults enrolled in the longitudinal community-based Wisconsin Sleep Cohort Study with at least 30 minutes of REM sleep obtained from overnight in-laboratory polysomnography. Studies were repeated at 4-year intervals to quantify OSA. Repeated measures logistic regression models were fitted to explore the association between REM sleep OSA and prevalent hypertension in the entire cohort (n = 4,385 sleep studies on 1,451 individuals) and additionally in a subset with ambulatory blood pressure data (n = 1,085 sleep studies on 742 individuals). Conditional logistic regression models were fitted to longitudinally explore the association between REM OSA and development of hypertension. All models controlled for OSA events during non-REM sleep, either by statistical adjustment or by stratification....
