A Cardiosleep Research Program on Obstructive Sleep Apnea, Blood Pressure Control and Maladaptive Myocardial Remodeling

The objective of this proposal is to evaluate whether mandibular advancement device (MAD) is non-inferior to continuous positive airway pressure (CPAP) in the treatment of obstructive sleep apnea (OSA) and blood pressure reduction. OSA and hypertension are highly prevalent disorders with profound impacts on health. Apart from improving quality of-life, an effective OSA treatment could improve cardiovascular risk partly through blood pressure reduction, particularly in patients with high cardiovascular risk in whom blood pressure control is often suboptimal. Although CPAP is useful, the high non-acceptance and non-adherence preclude its widespread use. East Asians have a restrictive craniofacial phenotype that predisposes them to OSA and the associated cardiovascular stress. CPAP, while considered the first-line therapy for OSA, has failed to improve cardiovascular outcomes in randomized trials till date because it is poorly tolerated. MADs are oral appliances that correct the restrictive craniofacial phenotype present in East Asians by protruding the lower jaw to reduce upper airway collapsibility. MADs are better tolerated than CPAP, and this may be an important determinant of the overall effectiveness in treating OSA, and thus ameliorating the downstream adverse health outcomes. We hypothesize that MADs are non-inferior to CPAP in treating OSA and reducing cardiovascular risk by blood pressure reduction in East Asians. We will recruit East Asian subjects with hypertension and high cardiovascular risk for polysomnography. Patients diagnosed with OSA (n=220) will be randomized to MAD or CPAP groups in a 1:1 ratio for a treatment duration of 6 months. The primary endpoint is the 24-hour mean blood pressure as determined by ambulatory monitoring. The secondary endpoints include sleep-time systolic BP, target blood pressure, cardiovascular biomarkers, and myocardial remodeling. Association between OSA and silent paroxysmal atrial fibrillation will also be determined. If MADs are shown to be effective, the next step is to evaluate our novel device- drug-eluting MAD that the team is developing.

Comparison of High Flow Nasal Cannula Therapy to Nasal Oxygen as a Treatment for Obstructive Sleep Apnea in Infants

This is a small pilot study that will compare High Flow Nasal Cannula (HFNC) therapy to oxygen nasal cannula therapy on infants who have obstructive sleep apnea (OSA) and are scheduled for a clinically ordered sleep study called polysomnography (PSG). The HFNC procedure uses humidified room air delivered by nasal cannula at higher pressures and will test if HFNC can control OSA in infants better or as well as low flow nasal oxygen, the current clinical standard of care. All the infants in the study will have a brief test period of about 3 to 4 hours with the HFNC before participants begin their standard clinical PSG for titration of oxygen by nasal cannula for treatment of OSA.

Obstructive Sleep Apnea Treatment on Cardiovascular Events in Patients With Acute Cardiogenic Pulmonary Edema: CPAP-CARE STUDY.

Despite the advances in the treatment of acute cardiogenic pulmonary edema (ACPE), the readmissions rates and cardiovascular events remain very high. In this context, it is possible that other potential risk factors may influence the poor prognosis of the ACPE. One of these potential candidates is Obstructive Sleep Apnea(OSA). This study was designed to evaluate the impact of OSA treatment with CPAP in consecutive patients with ACPE. The primary outcome will be to evaluate the impact of CPAP on the recurrence of ACPE in the 1-year follow-up.

Medico-economics and QoL of Obese Patients Followed by Medical Analysis Laboratories (BIOSAOS )

Obesity is a major risk factor for obstructive sleep apnea (OSA). However, OSA is still largely under diagnosed in patients with a high cardiovascular risk. In this population the STOP-BANG questionnaire facilitates OSA screening. Moreover, blood bicarbonate concentration is a simple tool to screen for chronic respiratory disease and if elevated, is a marker of cardiometabolic comorbidities in obese patients. A combination of blood bicarbonate concentration and STOP BANG score could provide a cost-effective method of screening for OSA in obese patients. Such screening could enable earlier management and might significantly reduce the costs of treatment and improve the quality of life of patients at 2 years.

Transcutaneous CO2 Monitoring at Home for Children With Neuromuscular Disease

There is an unmet demand for the evaluation of nocturnal hypoventilation in children with NMD. An ambulatory screening tool that can reliably facilitate timely diagnosis and treatment in these children would be invaluable. If an ambulatory, at home, tcCO2 monitoring device is shown to be diagnostically accurate, sleep physicians would be able to triage children on existing waiting lists and optimize screening of nocturnal hypoventilation as recommended by international guidelines.

Dexmedetomidine Supplemented Analgesia in Patients at High-risk of Obstructive Sleep Apnea

Obstructive sleep apnea (OSA) is a common sleep disturbance that can cause intermittent hypoxia, hypercapnia, and sleep structure disorders. The presence of OSA is associated with worse outcomes after surgery including increased incidence of complications. High-flow nasal cannula (HFNC) therapy can improve oxygenation of OSA patients by maintaining a certain positive pressure in the nasopharyngeal cavity. Previous studies showed that, dexmedetomidine supplemented analgesia can improve sleep quality and pain relief. The investigators hypothesize that, for high-risk OSA patients following major non-cardiac surgery with HFNC therapy, dexmedetomidine supplemented analgesia can improve sleep quality. The purpose of this pilot randomized controlled trial is to investigate the impact of dexmedetomidine supplemented analgesia on sleep quality in high-risk OSA patients after major non-cardiac surgery.

Neurocognitive and Health Impact of Sleep Apnea in Elderly Veterans With Comorbid COPD

Cognitive dysfunction in the aging Veteran population is a growing health concern in the Veterans Health System. It is not known whether OSA coexisting with COPD will enhance the risk for cognitive dysfunction. The investigators sought to investigate whether these two highly prevalent diseases, that often co-exist as the 'Overlap Syndrome', combine to enhance cognitive impairment in the elderly Veteran population. Thus, the investigators will study whether elderly patients with Overlap syndrome have increased cognitive deficits compared with OSA or COPD alone. Additionally, treatment of OSA with positive airway pressure (PAP) has been shown to improve neurocognitive function in moderate-to-severe OSA while cognitive decline in COPD may be reversible through treatment with long-term oxygen therapy. The investigators will also study whether treatment with positive airway pressure (PAP) and supplemental oxygen vs PAP alone will improve cognitive function and improve quality of life of elderly Veterans.

Obstructive Sleep Apnea in Survivors of Hodgkin Lymphoma Treated With Thoracic Radiation

While thoracic radiation therapy (TRT) has been a primary component in successful treatment of Hodgkin lymphoma, exposure to this treatment has been associated with significant cardiovascular, cerebrovascular, and pulmonary morbidity in long-term survivors. Survivors of Hodgkin lymphoma (HL) are also at risk for fatigue and excessive daytime sleepiness. Insufficient sleep is recognized as an important public health concern, and is associated with cardiovascular disease, diabetes, obesity, neurocognitive problems, and reduced quality of life and productivity. Survivors of HL, who are already at risk for cardiac and neurologic morbidity due to their treatment exposures, could face catastrophic cardiovascular and cerebrovascular events with the added risk associated with obstructive sleep apnea (OSA). The investigators propose to examine indices of sleep quality using polysomnography, and associated neurocognitive performance, brain MRI, and structure and strength of neck muscles in 220 long-term adult survivors of Hodgkin lymphoma treated with thoracic radiation. OBJECTIVES: To estimate the prevalence of OSA in adult survivors of HL treated with thoracic radiation, and compare the frequency to community controls matched on age, gender, race and body mass index. To identify specific therapeutic factors associated with OSA in adult survivors of HL treated with thoracic radiation. To identify biomarkers of OSA in adult survivors of HL treated with thoracic radiation. To examine associations between OSA and cardiac morbidity and brain integrity in the adult survivors of HL treated with thoracic radiation.

Dilator Muscle Activity in Health and Sleep Apnea

The role of control of peri-pharyngeal muscle tone in the pathogenesis of obstructive sleep apnea (OSA) is obvious: pharyngeal obstruction occurs only during sleep; and pharyngeal collapse occurs in almost all healthy subjects during anesthesia. Better understanding of these control mechanisms may help identifying the central components of the pathogenesis of OSA.
