To determine the prevalence of glaucoma in obstructive sleep apnea (OSA) patients and compare it with that of patients without OSA. Patients investigated for OSA using polysomnography at the sleep center of King Abdulaziz University Hospital were invited to participate in this cross-sectional case series study. American Academy of Sleep Medicine guidelines were used to diagnose OSA. Recruitment of patients with and without OSA was conducted from December 2013 to September 2015. Exclusion criteria included topical and systemic steroid use and presence of other ocular diseases. Two criteria, cup/disc ratio and visual field defects, were necessary for a glaucoma diagnosis. Among 84 adults enrolled, 44 (52%) had a confirmed diagnosis of OSA. Glaucoma prevalence was higher among individuals with OSA (16%) than among non-OSA individuals (8%), a difference that was not statistically significant. A consistent trend, which was not statistically significant after adjusting for cofounders, toward more glaucomatous changes was observed in OSA subjects. Although a trend toward higher glaucoma prevalence was observed in OSA patients, the difference was not statistically significant. As many variables contribute to the development of the two conditions, larger cohorts are needed to evaluate associations between glaucoma and OSA.

Studies focusing on the effects of lifestyle strategies on patients with obstructive sleep apnea (OSA) that go beyond body weight and explore body composition are currently scarce and inconclusive. The aim of this study was to evaluate the effects of a 12-month intensive life intervention program (ILI), based on a hypocaloric Mediterranean diet, on changes in the body composition parameters as assessed by abdominal computed tomography (CT) and the cardiorespiratory profile of patients with severe OSA and grade I-II obesity, compared to patients receiving standard care. Resultts:Thirty-four patients (30 males and four females) were randomly assigned to an intervention group (IG) ( = 18) or a control group (CG) (n = 16).

Challenges in Obstructive Sleep Apnea Management in Elderly Patients.

J Clin Med

December 2024

Department of Pulmonary Medicine, Saint-Pierre University Hospital, Brussels, Belgium and Université Libre de Bruxelles, 1000 Brussels, Belgium.

With the aging of the population, obstructive sleep apnea (OSA) in elderly patients is now more commonly seen in clinical practice. In older people, sleepiness is less marked than in younger patients, but insomnia symptoms are more common. Comorbidities are numerous and related to cardiometabolic and cognitive conditions.

: Obstructive sleep apnea (OSA) is recognized as an independent risk factor for diabetes mellitus type 2 (T2DM) development, which is twice as common in patients with OSA compared to non-OSA patients. : This study aimed to investigate changes in oxygen metabolism and their role in T2DM development among OSA patients through epigenetic processes via , , and enzymatic processes via SIRT1 and HIF-1α. : Based on polysomnography, apnea-hypopnea index and the presence of T2DM patients were divided into three groups: control group ( = 17), OSA group ( = 11), OSA&T2DM ( = 20) group.

: Continuous positive airway pressure (CPAP) is used to treat patients with obstructive sleep apnea (OSA) and has proven clinical efficacy for this condition. However, the objective method to determine the appropriate CPAP level for treatment is still unclear. Patients with OSA typically exhibit irregular respiratory efforts due to obstruction or narrowing of the upper airway during sleep.

Transoral robotic surgery (TORS) for tongue base reduction (TBR) and/or epiglottic surgery is an effective treatment option for selected patients with moderate to severe obstructive sleep apnoea (OSA). This systematic review aims to provide an up-to-date overview of current practices and challenges associated with TORS for OSA. PubMed and Embase databases were searched up to December 2022 following PRISMA guidelines.
