Analysis of the dynamic changes in the soft palate and uvula in obstructive sleep apnea-hypopnea using ultrafast magnetic resonance imaging

, 2014
Apnea and the respiratory cycle are dynamic processes in obstructive sleep apnea-hypopnea (OSAH), which occur only during sleep. Our study aimed to observe the dynamic changes in the soft palate and the uvula during wakefulness and sleep using ultrafast ...

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

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 ...

Early sleep apnea treatment in stroke (eSATIS) – a multicentre, randomised controlled, rater‐blinded, clinical trial: The association of post‐stroke cognition with sleep‐disordered breathing and its treatment

Journal of Sleep Research, Volume 34, Issue 2, April 2025.
Summary Sleep‐disordered breathing (SDB) is linked to cognitive dysfunction. Although SDB is common in stroke patients, the impact of SDB and its early treatment on cognitive functioning after stroke remains poorly investigated. Therefore, we explored the association between SDB and post‐stroke cognitive functioning, including the impact of early SDB ...

Sex‐based disparities in dopamine agonist response in patients with restless legs syndrome

Journal of Sleep Research, Volume 34, Issue 2, April 2025.
Summary This study aimed to investigate sex‐related differences in the response to ropinirole and pramipexole in patients with restless legs syndrome (RLS). By analysing clinical parameters and polysomnographic (PSG) findings, we sought to elucidate the potential factors related to sex disparities modulating treatment responses and sleep quality in RLS.
