Article Synopsis
  • This review discusses the noninvasive evaluation of cardiac autonomic nervous system activity (ANSA) through easily accessible parameters like heart rate (HR) and heart-rate variability (HRV), highlighting their importance in risk assessment for sudden cardiac death.
  • The translation of these parameters from controlled lab settings to real-world ambulatory environments faces challenges due to various uncontrolled factors such as blood pressure changes and physical activity.
  • To improve the accuracy of ANSA evaluations in everyday settings, the authors suggest using a multi-sensor and multiparametric approach, along with data fusion and machine-learning techniques.

Mean disease alleviation measures the effectiveness of Obstructive Sleep Apnea (OSA) treatments. It combines a patient's adherence to treatment normalized to their total sleep time and the treatment's efficacy as determined by the change in the apnea-hypopnea index. This metric fails to capture the patient's OSA-related symptoms, which are a key component and, in some cases, the primary component, of determining response to treatment.

Article Synopsis
  • The study investigates how obstructive sleep apnea (OSA) affects cognitive function, focusing on the role of hypoxemia (hypoxic burden) as a potential cause of white matter injuries in the brain.
  • Researchers analyzed data from 587 older adults, measuring the association between hypoxic burden and white matter hyperintensity volume (WMH), while considering other factors like ventilatory burden and arousal burden.
  • Findings revealed that an increase in hypoxic burden correlated with higher WMH volume, highlighting the importance of oxygen desaturation in understanding brain health in individuals with OSA.

Objective: Since 2011, otolaryngologists aiming to become certified in sleep medicine have had to complete an ACGME accredited sleep medicine fellowship. In addition to standard sleep medicine and sleep surgery fellowships, several institutions have developed hybrid ACGME sleep medicine programs that incorporate sleep surgery training. Our primary aims were to understand the balance between sleep medicine and surgical training requirements and the surgical volume of recent graduates across the three pathways.

Article Synopsis
  • - Recent studies found no cardiovascular benefits of CPAP treatment in adults with coronary artery disease (CAD) and obstructive sleep apnea (OSA), particularly among patients with excessive daytime sleepiness (EDS).
  • - A secondary analysis of the RICCADSA trial showed that after one year, adverse cardiovascular outcomes were not significantly different between patients with and without EDS who were not treated or nonadherent to CPAP.
  • - However, among patients who used CPAP for at least 4 hours a night, those without EDS had a significantly lower risk of serious cardiovascular events compared to those with EDS.

Obstructive sleep apnea (OSA) is unrecognized in as high as 80% of patients before surgery. When untreated, OSA increases a surgical patient's propensity for airway collapse and sleep deprivation lending to a higher risk for emergent re-intubation, prolonged recovery time, escalation of care, hospital readmission, and longer length of stay. We have reviewed the evidence regarding diagnostic performance of OSA screening methods and the impact of perioperative management strategies on postoperative complications among patients with diagnosed or suspected OSA who are undergoing orthopedic surgery.

Obstructive sleep apnea (OSA) is common in adults with coronary artery disease (CAD). OSA that occurs predominantly during rapid-eye movement (REM) sleep has been identified as a specific phenotype (REM-predominant OSA) in sleep clinic cohorts. We aimed to examine the association of REM-predominant OSA with excessive sleepiness, functional outcomes, mood, and quality of life in a CAD cohort, of whom 286 OSA patients with total sleep time ≥ 240 min, and REM sleep ≥ 30 min, were included.

Article Synopsis
  • There is uncertainty among international cardiologists about the advantages of diagnosing and treating obstructive sleep apnea (OSA) to improve outcomes in patients with atrial fibrillation (AF).
  • A survey of 863 cardiologists across 16 countries revealed mixed responses regarding OSA treatment, with only a third referring AF patients for OSA screening despite 70% believing randomized controlled trials are needed for better evidence.
  • While many cardiologists thought that treating both OSA and AF was more effective than treating AF alone, there remains a gap in practice, as only about half of the screened patients were prescribed CPAP therapy for OSA.

Purpose: Hypoglossal nerve stimulation (HNS) has been shown to treat obstructive sleep apnea (OSA) effectively. The aim of this study was to compare HNS with positive airway pressure (PAP) treatment regarding outcome parameters: (1) sleepiness, (2) apnea-hypopnea index (AHI), and (3) effectiveness.

Methods: Propensity score matching with nearest neighbor algorithm was used to compare outcomes of HNS and PAP therapy in a real-world setting.

Study Objectives: Upper airway stimulation (UAS) is an alternative treatment for obstructive sleep apnea that must be activated nightly. Although the implanted device offsets the mask- or pressure-related side effects often associated with continuous positive airway pressure therapy, some UAS recipients do not use the therapy consistently. This study qualitatively explored factors associated with UAS usage in obstructive sleep apnea patients.

Study Objectives: Upper airway stimulation (UAS) therapy is effective for a subset of obstructive sleep apnea (OSA) patients with continuous positive airway pressure (CPAP) intolerance. While overall adherence is high, some patients have suboptimal adherence, which limits efficacy. Our goal was to identify therapy usage patterns during the first 3 months of therapy to enable targeted strategies for improved adherence.

Unlabelled: The American Academy of Sleep Medicine (AASM) recommends that hypopneas be identified using a definition that is based on a ≥ 30% decrease in airflow associated with a ≥ 3% reduction in the oxygen saturation or an arousal (H3A) for diagnosis of obstructive sleep apnea (OSA) in adults. This conflicts with the Centers for Medicare & Medicaid Services definition, which requires a ≥ 4% decrease in the oxygen saturation to identify a hypopnea (H4) and does not acknowledge arousals. In 2018, the AASM Board of Directors constituted a Hypopnea Scoring Rule Task Force with a mandate to "create a strategy for adoption and implementation of the AASM recommended adult hypopnea scoring criteria among members, payers and device manufacturers.
