Nebula Study - Screener Apps and HSAT vs. PSG Comparison
Sleep ApneaObstructiveThis is a prospective, unblinded, open-label, single group study. All subjects will undergo concurrent screener app, HSAT testing, and in-lab polysomnography.
Sleep Apnea, Obesity and Pregnancy
ObesityPregnancyMain objective: Determine the prevalence of obstructive sleep apnea syndrome (OSA) in late pregnancy in a population of obese patients . Secondary objectives : Identify risk factors for OSA during pregnancy (age, parity, high blood pressure, snoring , weight, neck circumference, scores on symptoms of sleep apnea, ... ) . Compare perinatal morbidity among obese patients with OSA in late pregnancy with case-controls. Evaluate the evolution of a moderate or severe OSA 6 months after pregnancy. Material and methods Characteristics of the study: Interventional biomedical research Prospective Multicenter nonrandomized study Flow chart Patients will be included between 30 and 36 weeks of amenorrhea (WA) . Will rated from inclusion: age, parity, weight, height, BMI in early pregnancy, neck circumferrence, treated high blood pressure. As recommended in France, the main test results during the pregnancy follow-up will be recorded. At the inclusion visit will be conducted a Berlin Questionnaire and Epworth Score. Screening for OSA by nocturnal polysomnography will be performed between 30 and 36WA. This screening can be performed as an outpatient. In case of proven OSA patients will be offered an appropriate care by today's standards. Whatever the outcome of pregnancy, a second polysomnography will be performed 6 months after childbirth in case of OSA during pregnancy.
Outcome of IV Acetaminophen Use in Laparoscopic Cholecystectomies in Patients at Risk of OSA
CholecystitisCholelithiasis1 moreThe objective of this study is to determine if IV acetaminophen administered intraoperatively can decrease the dose of narcotics required for adequate pain control and shorten recovery time in the PACU specifically in obese patients at risk for obstructive sleep apnea.
Continuous Positive Airway Pressure (CPAP) for Fatigue in Patients With Multiple Sclerosis (MS)...
FatigueMultiple Sclerosis1 moreFatigue is a symptom present in 76 to 92% of people with multiple sclerosis (MS). Fatigue is usually described as an overwhelming sense of tiredness, lack of energy, and feeling of exhaustion which is different from sleepiness. Fatigue is also a symptom commonly seen in people with obstructive sleep apnea (OSA). The overall objective is to develop a non-pharmacological treatment for fatigue in MS. The objective of this study is to evaluate if treatment of OSA with continuous positive airway pressure (CPAP) improves fatigue in MS subjects with OSA and fatigue. This will be a small pilot randomized, double-blind, sham-controlled clinical trial; the control group will be treated with a sham-CPAP machine and intervention group will be treated with an auto-titration CPAP machine. The primary outcome measure will be improvement (decrease) in the Modified Fatigue Impact Scale from baseline. The duration of intervention will be 12 weeks to achieve a clinical response in the treatment group. After this intervention participants in both groups will be offered a referral to the sleep clinic of their preference for formal treatment as per standard of care.
Sedative Effects in Obstructive Sleep Apnea
Obstructive Sleep ApneaThe objective of this study is to determine the effect of dexmedetomidine infusion on the Apnea / Hypopnea Index (AHI) of individuals with previously documented obstructive sleep apnea. We hypothesize that dexmedetomidine infusion may reduce the AHI in patients with obstructive sleep apnea (OSA).
Hypnotics to Improve Polysomnography Yield: Eszopiclone vs Ramelteon?
Obstructive Sleep ApneaThis study is being conducted to determine if eszopiclone is as effective as ramelteon when used as a pre-medication (sleeping pill) in sleep studies performed to diagnose and treat sleep apnea.
Biomarkers in Obstructive Sleep Apnea Surgery
Obstructive Sleep ApneaRecent years have witnessed major advances in the understanding of the hormonal, metabolic, and biochemical changes that occur in obstructive sleep apnea (OSA). This project evaluates the biomarkers that measure the most significant health impacts of this disorder and creates a specimen bank that will facilitate evaluations of additional biomarkers in the future.
Brain Oxygenation and Hemodynamics During Sleep in Obstructive Sleep Apnea Sufferers
Obstructive Sleep Apnea SyndromeThe goal of this trial is to assess the performance of the OxiplexTS-an absolute near-infrared oximeter-as an instrument to measure brain oxygenation and hemodynamics in sleep medicine as well as in the broader field of cardiovascular/cerebrovascular diagnostics.
The Use of Psychomotor Vigilance Testing in the Assessment of Pediatric Obstructive Sleep Apnea...
Pediatric Obstructive Sleep ApneaObstructive sleep apnea results in decreased attentiveness and response times in patients. The objective of this study is to quantify these consequences in pediatric OSA patients using an already established tool for examining the results of sleep deprivation and fragmentation: psychomotor vigilance testing. PVT has been used in children, but has not been studied in pediatric OSA patients. This study aims to employ PVT along the normal course of diagnosis and treatment of pediatric OSA patients in our clinical practice at Arkansas Children's Hospital. The investigators hypothesize that pediatric OSA patients will exhibit decreased PVT scoring when compared to children without OSA, and that PVT can be used to diagnose and monitor treatment outcomes in these patients.
Effect of Treating Sleep Disorder Breathing in Patients With Resistant Hypertension
Sleep ApneaHypertensionThe investigators would like to investigate the effects of treating sleep apnea with a positive airway pressure device, either continuous (titrated) versus auto titrated on the control of blood pressure in patients with Resistant Hypertension.
