Respiratory safety of lemborexant in adult and elderly subjects with moderate‐to‐severe chronic obstructive pulmonary disease

Journal of Sleep Research, Volume 34, Issue 2, April 2025.
Lemborexant 10 mg, a dual orexin‐receptor antagonist (DORA), did not elicit respiratory depressant effects, as measured by peripheral oxygen saturation (SpO2) or apnea–hypopnea index (AHI), in subjects with moderate‐to‐severe chronic obstructive pulmonary disease (COPD).

Vascular Dynamics During Respiratory Arousal From Sleep Assessed by Oximeter‐Based Vascular Stiffness Measures

Journal of Sleep Research, EarlyView.
ABSTRACT Cortical arousals significantly impact obstructive sleep apnoea (OSA) pathophysiology and cardiovascular consequences, often mediated by sympathetic activation. While pulse oximetry (PPG) provides an accessible reflection of autonomic responses such as changes in pulse rate (PR) and pulse wave amplitude (PWA), the dynamic influence on other ...

Slow Wave Activity During Nocturnal Sleep in Hypersomnolence Disorder

Journal of Sleep Research, EarlyView.
ABSTRACT Slow waves during non‐rapid eye movement (NREM) sleep are associated with the restorative aspects of sleep. Previous research has suggested reduced normalized slow wave activity (SWA), particularly in the first cycle of NREM sleep, as a feature of hypersomnolence disorder (HD); however, the scarcity of existing research highlights the need for

Parapharyngeal Fat Pads as an Obesity‐Related Parameter for Apnea‐Hypopnea Index Severity

Journal of Sleep Research, EarlyView.
ABSTRACT In this study, the association between obstructive sleep apnea severity and the parapharyngeal fat pad volume is examined in a population‐based sample. We included 680 participants who underwent standardised overnight polysomnography between 2008 and 2012 as part of the Study of Health in Pomerania in a sleep laboratory in Greifswald, Germany.

Does Measurement Site Matter? A Comparison Between Finger, Forehead, and Toe Pulse Oximetry Measurements in Polysomnography

Journal of Sleep Research, EarlyView.
ABSTRACT Accurate peripheral blood oxygen saturation (SpO2) measurements are critical for evaluating sleep patients, particularly those with frequent desaturations due to pathological breathing events. We compared synchronised SpO2 measurements obtained from three anatomical sites (finger, forehead and toe) in patients undergoing routine Type 1 ...

The Relationship Between Resting State Quantitative EEG and Daytime Sleepiness Complaints in Parkinson's Disease

Journal of Sleep Research, EarlyView.
ABSTRACT Although many studies have reported the presence of daytime sleepiness in Parkinson's disease (PD), either a weak or no association has been found between self‐reported and current objective measures of daytime sleepiness in this population. Changes in resting state quantitative electroencephalography (qEEG) have been associated with increased

The Effects of Nasal and Multi‐Level Upper Airway Surgery on Upper Airway Collapsibility and Non‐Anatomical Endotypes in People With Obstructive Sleep Apnoea—A Pilot Study

Journal of Sleep Research, EarlyView.
ABSTRACT Nasal breathing is the preferred route of breathing during sleep. Indeed, nasal blockage can cause obstructive sleep apnoea (OSA) in otherwise healthy people. Whilst multi‐level pharyngeal surgery reduces OSA severity, efficacy varies and changes in OSA pathophysiology post‐surgery have not been well characterised.
