Continuous respiration monitoring is an important tool in assessing the patient's health and diagnosing pulmonary, cardiovascular, and sleep-related breathing disorders. Various techniques and devices, both contact and contactless, can be used to monitor respiration. Each of these techniques can provide different types of information with varying accuracy.

Total sleep time (TST) misperception has been reported in obstructive sleep apnea (OSA). However, previous findings on predictors were inconsistent and predominantly relied on single-night polysomnography, which may alter patients' sleep perception. We leveraged advances in wearable sleep staging to investigate predictors of TST misperception in OSA over multiple nights in the home environment.

Article Synopsis
  • Hypocretin deficiency leads to type 1 narcolepsy, which is associated with excessive daytime sleepiness and a high prevalence of overweight and obesity in patients.
  • A study compared energy expenditure in ten males with narcolepsy to nine healthy controls using respiration chamber calorimetry and doubly labelled water.
  • Results showed no significant differences in energy expenditure or physical activity between the two groups, suggesting that weight gain in narcolepsy might be influenced by factors other than metabolism, such as dietary habits.

Article Synopsis
  • * Researchers analyzed data from over 1500 patients and found that women reported higher sleepiness on the Epworth Sleepiness Scale compared to men, with specific age-related trends observed in different patient groups.
  • * Notably, in women with narcoleptic conditions, an increase in daytime sleepiness was linked to age, while weight gain appeared later, suggesting a complex relationship that warrants further research for targeted treatment approaches.
