Purpose: While the symptoms of narcolepsy are often amenable to treatment with sodium oxybate (SXB), the respiratory effects of long-term SXB treatment have not been systematically studied. Recent reports have implicated SXB with several cases of worsening sleep-related breathing disturbances and accidental death. In addition, these patients are at risk for obesity, which may aggravate co-morbid obstructive sleep apnea.
Methods: Based on a review of the literature and the clinical experience of the author, recommendations for the use of SXB in patients with sleep-disordered breathing have been developed.
Results: Among narcolepsy patients with evidence of sleep disordered breathing during baseline polysomnography, SXB should be prescribed only to those patients who fully comply with nasal continuous positive airway pressure therapy. The respiratory status of other SXB-treated patients should be periodically evaluated with nocturnal oximetry.
Conclusions: Based on the currently available data, physicians prescribing SXB should remain vigilant for the possible development of sleep-disordered breathing during long-term treatment with SXB.

Multidimensional characterization of craniofacial skeletal phenotype of obstructive sleep apnea in adults.
Eur J Orthod
December 2024
Professor, Department of Orthodontics, School of Dentistry, Kyung Hee University, Seoul 02453, Republic of Korea.
Objectives: We aimed to characterize a craniofacial skeletal phenotype (CSP) of adult obstructive sleep apnea (OSA) patients from a multidimensional perspective, exploring the impact of transverse skeletal discrepancy (TSD) on multivariable polysomnographic profiles.
Materials And Methods: This retrospective, cross-sectional study included 102 adult OSA patients. Sagittal, vertical, and transverse skeletal patterns were categorized on the cone beam computed tomography images.

Department of Orthodontics, Peking University School and Hospital of Stomatology, Beijing, China.
Background/purpose: Orofacial pain is common in dental practices. This study aimed to explore relationships between orofacial pain and sleep using the UK Biobank dataset and, based on epidemiological associations, to investigate the causal association using genome-wide association studies data.
Materials And Methods: First, a cross-sectional study was conducted with 196,490 participants from UK Biobank.
Severe bradycardia in patients with obstructive sleep apnoea and good early response to CPAP.
Sleep Breath
January 2025
Department of Cardiac and Vascular Diseases, Jagiellonian University Medical College, John Paul II Hospital, Prądnicka 80, Kraków, 31-202, Poland.
Background: Obstructive sleep apnoea (OSA) may lead to heart rhythm abnormalities including bradycardia. Our aim was to ascertain clinical and echocardiographic parameters in patients with OSA in whom severe bradycardia was detected in an outpatient setting, as well as to evaluate the efficacy of CPAP therapy on heart rate normalization at the early stages of treatment.
Methods: Fifteen patients mild, moderate or severe OSA and concomitant bradycardia were enrolled.
Obstructive sleep apnea and structural and functional brain alterations: a brain-wide investigation from clinical association to genetic causality.

Background: Obstructive sleep apnea (OSA) is linked to brain alterations, but the specific regions affected and the causal associations between these changes remain unclear.
Methods: We studied 20 pairs of age-, sex-, BMI-, and education- matched OSA patients and healthy controls using multimodal magnetic resonance imaging (MRI) from August 2019 to February 2020. Additionally, large-scale Mendelian randomization analyses were performed using genome-wide association study (GWAS) data on OSA and 3935 brain imaging-derived phenotypes (IDPs), assessed in up to 33,224 individuals between December 2023 and March 2024, to explore potential genetic causality between OSA and alterations in whole brain structure and function.

Sleep and circadian dysfunction are common nonmotor symptoms in patients with Parkinson disease (PD). Sleep and circadian dysfunction usually have a significant negative impact on quality of life and may also serve as markers to identify patients in the preclinical stage of PD. Sleep disturbances have different types in PD such as insomnia, excessive daytime sleepiness, rapid eye movement sleep behavior disorders, restless legs syndrome, and sleep-disordered breathing.
