Unlabelled: We report a case of a 65-year-old obese female who developed a unilateral nasal cerebrospinal fluid leak after starting autotitrating positive airway pressure therapy for obstructive sleep apnea. The cerebrospinal fluid leak was confirmed by β-2 transferrin testing of the nasal fluid, as well as by identification of the leak through the anterior cribriform plate after administration of intrathecal fluorescein. The cerebrospinal fluid leak was successfully repaired endoscopically, and autotitrating positive airway pressure was reinitiated 1 month postoperatively.

Article Synopsis
  • Untreated obstructive sleep apnea (OSA) in acute ischemic stroke (AIS) patients increases health risks, making diagnosis and treatment difficult in this demographic.
  • The study involved 27 AIS inpatients at Cleveland Clinic, where portable monitoring (PM) was used to identify OSA, and those with severe cases were offered therapy called auto-titrating positive airway pressure (APAP).
  • Despite high ratings for ease of use of the PM device, only a small percentage of patients continued using the APAP treatment consistently, revealing significant barriers and the need for more research on better screening and treatment strategies for OSA in AIS patients.

Article Synopsis
  • This study compares the effectiveness of first-line auto-adjusting positive airway pressure (aPAP) therapy and second-line hypoglossal nerve stimulation (HGNS) therapy for treating obstructive sleep apnea (OSA) in patients who meet specific criteria.
  • Both therapies were analyzed based on pre- and post-treatment data, showing that after treatment, aPAP significantly reduced the apnea-hypopnea index (AHI) compared to HGNS, which had a higher AHI post-treatment.
  • Despite the higher AHI in the HGNS group, patients reported feeling less sleepy after treatment than those using aPAP, suggesting that HGNS may improve subjective sleepiness even if it doesn't reduce apnea events as much.

Background: The current standard treatment for obstructive sleep apnea (OSA), continuous positive airway pressure (CPAP), is characterized by a low adherence rate due to various factors including circuit-dependent carbon dioxide (CO) rebreathing, which can exacerbated by disparate factors, such as low PAP, use of auto-titrating PAP or ramps. However, risk factors for rebreathing are often overlooked or poorly understood in clinical practice. Therefore, our objective was to evaluate the extent of rebreathing occurring with commonly used CPAP masks across varying PAPs, tidal volumes, and respiratory rates.

Unlabelled: PURPOSE   : Continuous positive airway pressure (CPAP) is often the treatment of choice for obstructive sleep apnea (OSA). Short-term adherence and early perceived benefits are the best predictors of long-term adherence. The aim of this study was to determine the effect of telemonitoring in the first period of treatment with CPAP (auto-titrating PAP) on compliance and the long-term outcome.

Background: Obstructive sleep apnoea (OSA) involves repeated breathing pauses during sleep due to upper airway obstruction. It causes excessive daytime sleepiness and has other health impacts. Continuous positive airway pressure (CPAP) therapy is effective first line treatment for moderate to severe OSA.
