Sleep
-
To formulate the first classification of sleep related disorders and abnormal sexual behaviors and experiences. ⋯ A broad range of sleep related disorders associated with abnormal sexual behaviors and experiences exists, with major clinical and forensic consequences.
-
To evaluate the influence of chronotype on sleep stages and quantitative sleep EEG when sleep pressure is increased and sleep schedule remains constant. ⋯ These results add further support to a postulated difference in homeostatic sleep regulation between morning types and evening types, with morning types showing indications of a higher homeostatic response to sleep disruption.

The relationship of subjective sleep quality, pain, and quality of life in advanced cancer patients.
Cancer patients have been reported to complain about poor quality of sleep. This study evaluated the quality of sleep in this group, utilizing demographic data and clinical features of the cancers as assessment criteria. A secondary aim was to evaluate the correlation between the self-rated questionnaire for the quality of sleep with other instruments used in measuring pain and quality of life. ⋯ Quality of sleep in patients suffering from stage IV cancer was significantly decreased. Demographic data and clinical variables of cancers did not affect the PSQI Global Sleep Quality score. The use of the mediation model also provides evidence that quality of sleep, quality of life, pain, and opioids are strictly correlated each other.

To clarify the relationship between sleep instability and subjective complaints in patients with upper airway resistance syndrome (UARS). ⋯ Compared with age- and sex-matched controls, patients with UARS have higher electroencephalogram arousal indexes and important non-rapid eye movement sleep disturbances that correlate with subjective symptoms of sleepiness and fatigue. These disturbances are identifiable with sensitive measures such as CAP analysis but not with traditional diagnostic scoring systems.

The aim of the present study was to assess, intraindividually, the relationship among slow eye movements, electroencephalogram (EEG) power, and subjective measures of sleepiness during a 40-hour sleep deprivation comparing 2 experimental conditions: eyes-open and eyes-closed. ⋯ Results suggest that subjective and EEG changes associated with higher sleepiness are paralleled by an increase in slow eye movement activity, but this relationship exists almost exclusively with the eyes closed. Hence, its use in practical and operational contexts seems limited.
