Adaptive Servo-Ventilation In Acute Heart Failure Patients Protecting the Heart and Kidneys
open to eligible people ages 18 years and up
The primary hypothesis of this study is: the use of minute ventilation-adaptive servo-ventilation (MV-ASV) during hospitalization will mitigate deterioration in renal function and prevent kidney injury in patients admitted with acute heart failure (AHF) compared to those receiving usual care. We will validate and extend our pilot study by taking a deeper dive into the effects of ASV on diuretic dose, urine output and new and exciting biomarkers of renal function and kidney injury. If our hypothesis proves correct, it strongly suggests that ASV lessens injury to the kidney and could lead to a new paradigm for the treatment of AHF. When use of high dose of diuretics are anticipated or in whom chronic kidney disease (CKD) or acute kidney injury (AKI) is present on arrival to the Emergency Department, use of MV-ASV might decrease the amount of diuretics needed, allow for continued use of ACE inhibitors, and ultimately mitigate rises in creatinine and decreases in effective glomerular filtration. Since kidney injury is a major factor in those patients with early 30-day readmission following discharge, this therapy could become quite popular.

Effects of Upper Airway Muscle Training on OSA
open to eligible people ages 18-79
Obstructive sleep apnea (OSA) is a common disorder characterized by recurrent collapse of the upper airway during sleep. OSA patients have a small upper airway that is kept patent during wakefulness by a compensatory increase in upper airway (UA) dilator muscle (e.g. genioglossus) activity. At sleep onset this compensation is reduced or lost, resulting in upper airway narrowing or collapse. Previous studies of upper airway muscle training showed variable results on OSA, but so far there has not been any practical, long-term, systematic upper airway muscle training developed or studied as the treatment of OSA. In theory, strengthening the upper airway muscle with exercise training in theory helps maintain a patent airway during sleep. Therefore, investigators aim to test the hypothesis: 1) UA muscle training can improve sleep apnea in some patients with OSA, including those already receiving treatment with PAP or oral appliance therapy. 2) Muscle training is a viable therapy for a definable subset of OSA patients. Investigators hypothesize that patients with OSA who have mild or moderately compromised upper airway anatomy will benefit the most. 3)There will be a positive association between the changes in muscle function and improvement in OSA severity.

Multimodal Sleep Pathway for Shoulder Arthroplasty
open to eligible people ages 18 years and up
The purpose of the study is to investigate the efficacy of sleep medicine in the recovery of orthopaedic shoulder arthroplasty patients. The investigators hypothesize that a multimodal sleep pathway including non-pharmacological sleep hygiene interventions and the use of zolpidem can improve patient sleep, pain control, and subsequent recovery after undergoing total shoulder arthroplasty.

Obstructive Sleep Apnea Endotypes and Impact on Phenotypes of People Living With HIV
open to eligible people ages 18-65
The investigators seek to understand how the different underlying causes of OSA affect the way people living with HIV (PLWH) experience OSA. The investigators also want to understand how symptoms of obstructive sleep apnea improve with treatment, and if this too, is affected by the underlying cause of OSA in that individual

Remote Sleep Apnea Management
open to eligible people ages 18 years and up
Although obstructive sleep apnea, a breathing disorder during sleep, is prevalent and recognized as a major public health concern, most Veterans with this disorder are undiagnosed and therefore untreated. Access to sleep laboratories for testing is limited particularly for those Veterans living in rural areas and Veterans with disabilities that prevent travel to a sleep center. The goal of this study is to compare a web-based telehealth management strategy to in-person management. The telehealth pathway will enable Veterans to be diagnosed and treated without visiting a sleep center. The investigators believe that telehealth management will increase Veterans' access to this specialized care at a cost that is less than in-person delivery but with similar improvements in daytime function.

Self-Management of Continuous Positive Airway Pressure Settings
open to eligible people ages 18-70
Obstructive sleep apnea (OSA) is a major chronic condition affecting the quality of life of millions of Americans. Per the Institute of Medicine new treatment adherence strategies are needed to help improve the quality of care, reduce social and economic costs, and help those with chronic conditions, including OSA, live healthier and more productive lives through better management of their conditions. Adherence with continuous positive airway pressure (PAP) therapy is disappointingly low, and new methods to increase both the use and efficacy of therapy are needed. Historically, patients have not been formally instructed to adjust their pressure settings on their PAP devices; practically, however, allowing patients to adjust their pressure settings fosters engagement, self-confidence, and control with therapy.

The Effect of Melatonin on Sleep and Ventilatory Control in Obstructive Sleep Apnea
open to eligible males ages 18-70
Our hypothesis is that oxidative stress induced during repeated apneas in obstructive sleep apnea (OSA) patients alters the neural control of breathing which destabilizes ventilatory control and exacerbates OSA. Thus antioxidant treatment has the potential to reduce OSA severity. Melatonin is a hormone which regulates sleep patterns, but it is also a potent antioxidant. Melatonin production is suppressed when the eyes register light so people with healthy sleep exhibit a peak in blood serum levels around 2am which then decreases towards morning. OSA patients exhibit lower melatonin levels with a later peak around 6am which then extends later into the day. This abnormal pattern is thought to compound difficulty falling asleep and daytime mental fatigue. Therefore the potential benefits of melatonin treatment in OSA patients are two-fold: most importantly via its antioxidant actions melatonin may reduce chemoreflex sensitivity, stabilize ventilatory control and reduce OSA severity; by normalizing sleep phase melatonin may also allow patients to fall asleep easier and wake more refreshed.

The Pathogenesis of OSA in People Living With HIV
open to eligible people ages 40-79
The purpose of this study is to help us understand how HIV and/or Anti-Retroviral Therapy (ART) may predispose individuals to Obstructive Sleep Apnea (OSA). The traditional risk factors for OSA are weight and age. However, people living with HIV on ART seem to have OSA even when they are thin and young. The study involves a detailed physiological sleep study and an MRI of the head and neck to understand the underlying cause of OSA in those with and without HIV.

Tissue-specific Insulin Resistance in Obstructive Sleep Apnea: Role of Hypoxia
open to eligible people ages 40-70
Obstructive sleep apnea (OSA) is a common condition associated with significant adverse health outcomes. Our overarching hypothesis is that patients with OSA and hypoxia (H-OSA) have greater degrees of insulin resistance in both liver and adipose tissue when compared to those without hypoxia (NH-OSA) thus leading to increased risk for the development of diabetes in the former group.

Whole Body Vibration for OSA
open to eligible people ages 21-60
Obstructive Sleep Apnea (OSA) is a serious medical condition which is increasing in the United States and significantly increases risks for other diseases, morbidity and mortality. The most common treatment for OSA is CPAP (Continuous Positive Airway Pressure), but this intervention has low patient compliance, significant expense ($800-2,000/set), and high inconvenience. Whole Body Vibration (WBV) training is a novel OSA intervention which could have higher patient compliance, low expense, and potentially lower morbidity and mortality and improved quality of life in this increasing patient population.

Chronic Moderate Sleep Restriction in Older Adults
Sorry, in progress, not accepting new patients
Higher rates of mortality have been found both in short sleepers (< 6 hr/night) and long sleepers (> 8 hr/night), but there has been little experimental investigation of the effects of chronic, moderate sleep loss in long or average sleepers. Some scientists argue that older adults might be particularly vulnerable to negative effects of sleep loss, whereas other scientists argue that many older adults spend too much time in bed, and that moderate reduction of time-in-bed could help increase the quality of their sleep, and could even promote health and longevity, particularly in long sleepers. At 4 sites across the US, we will conduct a large (200 people), randomized, controlled, 5- year study to examine whether a 1-hour reduction of time spent in bed for 12 weeks has negative or positive effects on multiple health-related outcomes, including inflammation, sleepiness, body weight, mood, glucose regulation, quality of life, incidence of illness, and incidence of automobile accidents in older long sleepers as compared to older average sleepers.

Extracellular microRNA: Biomarkers of Endothelial Dysfunction in Obese Adolescents & Adults With Obstructive Sleep Apnea
Sorry, not yet accepting patients
Using a prospective observational approach and a clinical trial design comparing the effectiveness of continuous positive airway pressure to diet and exercise, investigators plan to evaluate how obstructive sleep apnea (OSA) leads to endothelial dysfunction in adolescents and young adults and whether treatment of OSA can improve endothelial dysfunction. Concurrently, investigators will measure miR 92a/miR 210 levels in all subjects at baseline and following therapy to determine whether miR 92a/miR 210 levels reliably predict endothelial dysfunction in patients and responses to therapy.

Obstructive Sleep Apnea and Arousal Threshold in Patients With Post-traumatic Stress Disorder
Sorry, currently not accepting new patients, but might later
Obstructive sleep apnea (OSA) has traditionally been attributed only to a collapsible upper airway. However, it is increasingly recognized that multiple additional non-anatomical mechanisms contribute to the disease. Higher rates of OSA in patients with post-traumatic stress disorder (PTSD) than in those without PTSD have been reported however the mechanism behind this increased prevalence has not been investigated. Our hypothesis is that patients with PTSD have a predisposition to OSA due to a lower respiratory arousal threshold (wake up too easily) than patients without PTSD. The goal of this project will be to study and compare the ArTH in patients with PTSD and those without. In addition, we plan to see whether medications can be used to increase the arousal threshold and treat OSA in patients with PTSD.

Sleep Disordered Breathing in Acute Congestive Heart Failure
Sorry, not yet accepting patients
The goal of this study is to determine if sleep disordered breathing results in a measurable degree of overnight myocardial stress/injury in patients with acutely decompensated congestive heart failure. A secondary goal is to determine of a period of medical management attenuates this sleep disordered breathing-induced cardiac injury in this patient population.

Sleep for Stroke Management and Recovery Trial
Sorry, not yet accepting patients
The purpose of this study is to determine whether treatment of obstructive sleep apnea (OSA) with positive airway pressure starting shortly after acute ischemic stroke or high risk TIA (1) reduces recurrent stroke, acute coronary syndrome, and all-cause mortality 6 months after the event, and (2) improves stroke outcomes at 3 months in patients who experienced an ischemic stroke.

Survivorship Care in Reducing Symptoms in Young Adult Cancer Survivors
Sorry, in progress, not accepting new patients
This randomized clinical trial studies survivorship care in reducing symptoms in young adult cancer survivors. Survivorship care programs that identify the needs of young adult cancer survivors and ways to support them through the years after treatment may help reduce symptoms, such as pain, fatigue, sleep disturbance, depression, and distress, in young adult cancer survivors.

Suvorexant: A Dual Orexin Receptor Antagonist for Treating Sleep Disturbance in Posttraumatic Stress
Sorry, not yet accepting patients
Post-traumatic stress disorder (PTSD) is a common consequence of combat that can result in trauma-related hyperarousal and sleep disturbances. Poor sleep, one of the most common complaints in Veterans with PTSD, can be distressing, impair concentration and memory, and contribute to physical health conditions, such as metabolic syndrome, inflammation, and cardiovascular disease. The orexin neuropeptide system underlies both sleep and stress reactivity. Suvorexant, a drug that reduces orexin, improves sleep in civilians, but has not yet been tested in Veterans with PTSD. This study will test whether suvorexant can improve sleep disturbances and PTSD symptoms in Veterans. Suvorexant may benefit Veterans by improving sleep quickly while also reducing PTSD symptoms over the long term, and with fewer side effects that were common in previous medications used to treat these conditions. Improving Veterans' sleep and PTSD symptoms could lead to better emotional and physical well-being, quality of life, relationships, and functioning.

The Effect of Obstructive Sleep Apnea and Its Treatment on Decision Making
Sorry, accepting new patients by invitation only
Obstructive sleep apnea (OSA) is an extremely common disease with inadequately explored neurocognitive consequences. The investigators will study OSA patients before and after treatment to understand how OSA changes decision making abilities, and whether treatment can reverse such cognitive changes. These results could provide deeper insight into how OSA affects decision making either temporarily or permanently, and provide another rationale or motivation for treatment of OSA in adults.

The Impact of Venlafaxine on Apnea Hypopnea Index in Obstructive Sleep Apnea
Sorry, in progress, not accepting new patients
The investigators hypothesis is that obstructive sleep apnea (OSA) patients with a low arousal threshold may wake up too early during a respiratory event, before upper airway muscles can be activated to achieve stable ventilation. Thus, strategies to manipulate the respiratory arousal threshold could potentially improve the quality of sleep and sleep disordered breathing. Agents that raise arousal threshold are therefore likely to benefit some patients with OSA. The overall goal of this project is to determine the importance of the arousal threshold in OSA, determine which patients might benefit from a raised arousal threshold, and test this hypothesis by using pharmacological manipulation of the arousal threshold to achieve this goal.
