Study Objective: Animal data suggest that Δ(9)-TetraHydroCannabinol (Δ(9)THC) stabilizes autonomic output during sleep, reduces spontaneous sleep-disordered breathing, and blocks serotonin-induced exacerbation of sleep apnea. On this basis, we examined the safety, tolerability, and efficacy of dronabinol (Δ(9)THC), an exogenous Cannabinoid type 1 and type 2 (CB1 and CB2) receptor agonist in patients with Obstructive Sleep Apnea (OSA).
Design And Setting: Proof of concept; single-center dose-escalation study of dronabinol.
Participants: Seventeen adults with a baseline Apnea Hypopnea Index (AHI) ≥15/h. Baseline polysomnography (PSG) was performed after a 7-day washout of Continuous Positive Airway Pressure treatment.
Intervention: Dronabinol was administered after baseline PSG, starting at 2.5 mg once daily. The dose was increased weekly, as tolerated, to 5 mg and finally to 10 mg once daily.
Measurements And Results: Repeat PSG assessments were performed on nights 7, 14, and 21 of dronabinol treatment. Change in AHI (ΔAHI, mean ± SD) was significant from baseline to night 21 (-14.1 ± 17.5; p = 0.007). No degradation of sleep architecture or serious adverse events was noted.
Conclusion: Dronabinol treatment is safe and well-tolerated in OSA patients at doses of 2.5-10 mg daily and significantly reduces AHI in the short-term. These findings should be confirmed in a larger study in order to identify sub-populations with OSA that may benefit from cannabimimetic pharmacologic therapy.

Background: Patients with obstructive sleep apnea (OSA) frequently experience sleep disturbance and psychological distress, such as depression and anxiety, which may have a negative impact on their health status and functional abilities. To gain a more comprehensive understanding of the symptoms of depression, anxiety, and sleep disturbance in patients with OSA, the current study utilized network analysis to examine the interconnections among these symptoms.
Methods: Depressive and anxiety symptoms were evaluated using the Hospital Anxiety and Depression Scale (HADS), and sleep disturbance symptoms were evaluated using the Pittsburgh Sleep Quality Index (PSQI).

Obstructive sleep apnea (OSA) patients have varying degrees of cognitive impairment, but the specific pathogenic mechanism is still unclear. Meanwhile, poor compliance with continuous positive airway pressure (CPAP) in OSA prompts better solutions. This study aimed to identify differentially expressed genes between the non-obese OSA patients and healthy controls, and to explore potential biomarkers associated with cognitive impairment.

As available treatments in obstructive sleep apnea are all associated with side-effects or adherence problems, there is a need for alternative treatment options. In this randomized, open, parallel-group intervention study, the effect of head extension by cervical collar was evaluated in patients with moderate obstructive sleep apnea. One-hundred patients with moderate obstructive sleep apnea (apneas and hypopneas per estimated hours asleep = respiratory events index: 15-30) were randomized to either lifestyle intervention, or cervical collar in combination with lifestyle intervention.

Nearly one billion individuals worldwide suffer from obstructive sleep apnea (OSA) and are potentially impacted by related neurodegeneration. TFEB is considered a master regulator of autophagy and lysosomal biogenesis, but little is known about its role in neuronal oxidative stress and resultant injury induced by OSA. This study aimed to investigate these issues.

Aim: Sleep apnoea syndrome (SAS) is a common sleep disorder associated with heightened cardiovascular risks, yet sex-specific differences in these risks remain unclear.
Methods: This retrospective observational cohort study utilized the JMDC Claims Database, covering >5 million individuals in Japan. We analyzed data from 4,173,702 individuals (2,406,930 men, 1,766,772 women) after excluding those with central SAS, cardiovascular disease, and incomplete lifestyle questionnaire data.
