Metrology of two wearable sleep trackers against polysomnography in patients with sleep complaints

Journal of Sleep Research, Volume 34, Issue 2, April 2025.
Summary Sleep trackers are used widely by patients with sleep complaints, however their metrological validation is often poor and relies on healthy subjects. We assessed the metrological validity of two commercially available sleep trackers (Withings Activité/Fitbit Alta HR) through a prospective observational monocentric study, in adult patients ...

Intermittent hypoxia increases lipid insulin resistance in healthy humans: A randomized crossover trial

Journal of Sleep Research, Volume 34, Issue 2, April 2025.
This scheme illustrates the main results of the present study showing an increase in circulating free fatty acids (FFA) that are likely to be related to several mechanisms like decrease in FFA insulin sensitivity and increase in FFA production. Significant changes are labelled in white, and non‐significant or hypothesis are labelled in pale green ...

Association between obstructive sleep apnea (OSA) and COVID‐19 severity

Journal of Sleep Research, Volume 34, Issue 2, April 2025.
Summary Obstructive sleep apnea and sleep‐related hypoxia have been associated with higher rates of hospitalization and mortality among patients with Coronavirus disease 2019 (COVID‐19). We further explored the association between obstructive sleep apnea, COVID‐19 severity and related mortality.

The dynamics of cyclic‐periodic phenomena during non‐rapid and rapid eye movement sleep

Journal of Sleep Research, Volume 34, Issue 2, April 2025.
Summary Sleep is a complex physiological state characterized by distinct stages, each exhibiting unique electroencephalographic patterns and physiological phenomena. Sleep research has unveiled the presence of intricate cyclic‐periodic phenomena during both non‐rapid eye movement and rapid eye movement sleep stages. These phenomena encompass a spectrum

The effects of simulated obstructive apnea and hypopnea on arrhythmic potential in healthy subjects [PDF]

, 2018
Preliminary evidence supports an association between OSA and cardiac dysrhythmias. Negative intrathoracic pressure, as occurring during OSA, may provoke cardiac dysrhythmias.

Feasibility and usability of three consecutive nights with self‐applied, home polysomnography

Journal of Sleep Research, Volume 34, Issue 2, April 2025.
Summary In‐laboratory polysomnography, the gold‐standard for diagnosing sleep disorders, is resource‐demanding and not conducive to multiple night evaluations. Ambulatory polysomnography, especially when self‐applied, could be a viable alternative. This study aimed to assess the feasibility and reliability of self‐applied polysomnography over three ...
