BACKGROUND: Suboptimal continuous positive airway pressure (CPAP) adherence in obstructive sleep apnea (OSA) clinical trials involving predominantly Caucasian males limits interpretability and generalizability. We examined predictors of CPAP adherence in a clinical trial enriched with minorities. METHODS: The Sleep Apnea Stress Study - a randomized double-blind, sham-controlled trial of moderate-severe OSA patients - included participants with complete 8-week adherence data (n=138)...

A growing body of evidence supports a bidirectional relationship between post-traumatic stress disorder (PTSD) and sleep disturbances. Fragmented sleep induced by sleep-related breathing disorders, insomnia, and nightmares impacts recovery and treatment outcomes and worsens PTSD symptoms. Despite recent attention, management of these disorders has been unrewarding in the setting of PTSD. This review summarizes the evidence for empirically supported treatments of these sleep ailments as it relates to PTSD including psychotherapeutic and pharmacologic interventions...

PURPOSE: Obstructive sleep apnea (OSA) is associated with increased levels of systemic inflammatory markers, increased arterial stiffness, and endothelial dysfunction, which may lead to increased cardiovascular risk. We aimed to quantify the effects of continuous positive airway pressure (CPAP) on cardiovascular biomarkers and to establish predictors of response to CPAP. METHODS: We searched PubMed and the Cochrane Library from inception to May 31, 2017. Randomized controlled trials (RCTs) assessing the efficacy of CPAP on high-sensitivity C-reactive protein (hs-CRP), interleukin 6 (IL-6), tumor necrosis factor- alpha (TNF-α), augmentation index (AIx), pulse wave velocity (PWV), and flow-mediated dilatation (FMD) in patients with OSA were selected by consensus...

OBJECTIVE: Untreated obstructive sleep apnea (OSA) is a risk factor for cardiovascular disease including myocardial infarction (MI), congestive heart failure (CHF), and atrial fibrillation (AF). Continuous positive airway pressure (CPAP) is an effective treatment for OSA; however, compliance with CPAP can be challenging for some patients. The objective of this study was to investigate whether uvulopalatopharyngoplasty (UPPP) reduced the risk of cardiovascular complications for patients with OSA...

BACKGROUND: Implantable hypoglossal nerve upper airway stimulation (HNS) is a novel, FDA approved strategy for management of moderate to severe obstructive sleep apnea(OSA) patients with continuous positive airway pressure (CPAP) therapy intolerance or failure. Due to proximity of Cardiac Implantable Electronic Devices (CIED) and this stimulator, interaction between these devices is theoretically possible. OBJECTIVE: The purpose of this study was to assess interactions between implantable hypoglossal nerve upper airway stimulator device and cardiac implantable electronic devices...

The upper airway (UA) in humans is commonly modeled as a Starling resistor. However, negative effort dependence (NED) observed in some patients with obstructive sleep apnea (OSA) contradicts predictions based on the Starling resistor model in which inspiratory flow is independent of inspiratory driving pressure when flow is limited. In a respiratory bench model consisting of a collapsible tube and an active lung model (ASL5000), inspiratory flow characteristics were investigated in relation to upstream, downstream and extra-luminal pressures (denoted as Pus, Pds and Pout, respectively) by varying inspiratory effort (muscle pressure) from -1 to -20 cmH2 O in the active lung...

Respiratory complications are potential causes of death in patients with spinal cord injury (SCI). Nocturnal swallowing could be related to transient arousals, and lead to fragmented sleep in SCI patients. However, the impact of nocturnal swallowing on breathing and sleep physiology in SCI is unknown. The objectives of this study were (1) to determine whether nocturnal swallowing is more common in SCI than in able-bodied subjects, (2) to determine the role of nocturnal swallowing on arousal threshold in SCI individuals with sleep-disordered breathing (SDB), (3) to determine the effect of CPAP treatment on nocturnal swallowing...

BACKGROUND: Mechanical ventilation causes lung injury and systemic inflammatory responses in preterm sheep, and is associated with bronchopulmonary dysplasia (BPD) in preterm infants. Budesonide added to surfactant decreased BPD by 20% in infants. OBJECTIVE: Determine the effects of budesonide and surfactant on injury from high tidal volume (VT) ventilation in preterm lambs. METHODS: Ewes at 125 {plus minus} 1 day GA had fetal surgery to expose fetal head and chest with placental circulation intact...

PURPOSE: Cumulative evidence supports the clear relationship of obstructive sleep apnea (OSA) with cardiovascular disease (CVD). And, adherence to continuous positive airway pressure (CPAP) treatment alleviates the risk of CVD in subjects with OSA. Vascular endothelial growth factor (VEGF), a potent angiogenic cytokine regulated by hypoxia-inducible factor, stimulates the progression of CVD. Thus, whether treatment with CPAP can actually decrease VEGF in patients with OSA remains inconclusive...

A preterm neonate born at 27 weeks, with a birth weight of 555 g, was on continuous positive airway pressure (CPAP) for apnoea of prematurity and initially received total parenteral nutrition (TPN) through the umbilical venous catheter. Peripherally inserted central catheter (PICC) was inserted in the left basilica vein on day 8 to continue TPN. The baby developed respiratory distress with persistent hypoxia after TPN was initiated through the PICC line. The baby required mechanical ventilation due to worsening of respiratory distress, and chest X-ray, as well as ultrasound conducted 12 hours, postinfusion of TPN revealed right-sided pleural effusion...

RATIONALE: General practitioners play a passive role in obstructive sleep apnea (OSA) management. Simplification of the diagnosis and use of a semi-automatic algorithm for treatment can facilitate the integration of general practitioners, which has cost advantages. OBJECTIVE: To determine differences in effectiveness between primary healthcare area (PHA) and in-hospital specialized management protocols during six months of follow-up. METHOD: A multicenter, non-inferiority, randomized, controlled trial with two open parallel arms and a cost-effectiveness analysis was performed in six tertiary hospitals in Spain...

Background: Endothelial dysfunction, a pathophysiologic determinant of atherogenesis, has been found to occur in obstructive sleep apnea syndrome (OSA) and is improved by continuous positive airway pressure (CPAP). However, the efficacy of CPAP therapy is limited by variable adherence. Alternative treatment strategies are needed. The impact of polyphenols on endothelial function has never been evaluated in OSA. Objective: We evaluated the impact of 1-mo supplementation with grape juice polyphenols (GJPs) on the reactive hyperemia index (RHI), a validated measure of endothelial function in patients with severe OSA...

PURPOSE: Previous research has reported that inspiratory muscle weakness is critical to decreased exercise tolerance and exercise tolerance improves with 10 cmH2O pressure support ventilation in patients with chronic obstructive pulmonary disease (COPD).

This report describes the case of a hypertensive 51-year-old male with a 3-year history of peritoneal dialysis. We followed the patient through his diagnosis of severe obstructive sleep apnea (OSA) and treatment with continuous positive airway pressure (CPAP). Therapeutic use of CPAP led to the improvement of not only sleep-related problems, but also cognitive function and quality of life. To our knowledge, this is the first paper describing the benefits of long-term CPAP treatment in an OSA patient undergoing dialysis...

This study aimed to explore lipoprotein metabolism in Obstructive Sleep Apnea (OSA) and the effects of continuous positive airway pressure (CPAP). We studied 15 men with severe OSA (apnea-hypopnea index, AHI ≥30 events/hour) and 12 age, body mass index and waist circumference-matched volunteers without OSA (AHI <5 events/hour). Carotid intima-media thickness (CIMT) was determined by a blind examiner. After 12 hours fasting, a triglyceride-rich chylomicron-like emulsion, labeled with [14C]-cholesterol ester and [3H]-triolein was injected intravenously followed by blood samples collection at pre-established time...
