INTRODUCTION Adenotonsillar hypertrophy (AH) is considered the most common cause of upper respiratory tract obstruction among children. It results in a spectrum of symptoms from mouth breathing, nasal obstruction, hyponasal speech, snoring, and obstructive sleep apnea (OSA) to growth failure and cardiovascular morbidity. Adenotonsillectomy is a typical strategy for patients with AH, but may lea...

Cardiovascular and thermophysiological changes accompany the decision to fall asleep. A relationship between core body temperature and heart rate variability (HRV) especially during the sleep onset episode is suggested, but only few data are available, investigating a relationship between skin temperature and HRV at this time span. This study was aimed to elucidate the pattern of body temperatu...

Some studies have shown that people living near a mobile phone base station may report sleep disturbances and discomfort. Using a rat model, we have previously shown that chronic exposure to a low-intensity radiofrequency electromagnetic field (RF-EMF) was associated with paradoxical sleep (PS) fragmentation and greater vasomotor tone in the tail. Here, we sought to establish whether sleep dist...

Typical disposable Ag/AgCl electrodes have potential drawbacks from a long-term measurement perspective. Particularly, they can cause an allergic reaction of the skin and can detach in case of sweating during physical activity or sleep. As they are disposable, the electrodes cannot be removed for cleaning. They must be connected to a device with separate cables, which adds to the wearer’s disco...

Background: There is a well-established reciprocal relationship between pain and poor sleep. Therefore, we evaluated whether an approved sleep-promoting drug, lemborexant (LEM), could improve sleep in older adults who reported both insomnia pain. Methods: Study E2006-G000-304 (NCT02783729) was 1-month, placebo (PBO)- active-controlled study subjects (age ≥55y) with disorder. Those reporting som...
