NCT ID: NCT04621032 Completed - Clinical trials for Obstructive Sleep Apnea

Obstructive Sleep Apnea Destabilizes Myocardial Repolarization Homogeneity

Start date: September 1, 2016
Phase:
Study type: Observational [Patient Registry]

Literature shows that patients with obesity and Obstructive Sleep Apnea (OSA), both occurring independently, are more likely to develop cardiovascular diseases and sudden cardiac death (SCD). Assuming that ventricular depolarization is more stable than repolarization then QT interval parameters may be used for heart muscle repolarization assessment for those groups of patients. There were 121 patients included in the study, both - women and men, aging from 35-65 with visceral obesity. Only healthy patients were included - the ones who were not treated for any chronic disease, taking QT elongating drugs, or were not treated with Continuous Positive Airway Pressure (CPAP) therapy at that time.

NCT ID: NCT04609618 Completed - Clinical trials for Obstructive Sleep Apnea

Evaluatation of Appscent Device Safety and Effectiveness for Relief of Obstructive Sleep Apnea (OSA) Syndrome in Adults.

Start date: October 15, 2020
Phase: Early Phase 1
Study type: Interventional

Obstructive Sleep Apnea (OSA) syndrome is a disorder characterized by repetitive episodes of upper airway obstruction that occur during sleep. The standard treatment for apnea remains a device consisting of a pump and nasal mask that provide continuous positive airway pressure (CPAP). The major disadvantage of CPAP is the relatively low compliance. Appscent developed a non-contact effortless bedside solution based on the following: odors modify respiratory patterns during wake . Mildly trigeminal and pure olfactory odorants do not arouse or wake.

NCT ID: NCT04608331 Completed - Clinical trials for Obstructive Sleep Apnea

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

Start date: January 29, 2021
Phase: Phase 4
Study type: Interventional

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.

NCT ID: NCT04604392 Completed - Clinical trials for Sleep Apnea Syndrome

Evaluation of the Effects of Different Rapid Maxillary Expansion Appliances on Obstructive Sleep Apnea

Start date: July 1, 2016
Phase: N/A
Study type: Interventional

Rapid maxillary expansion (RME) is a commonly used orthodontic treatment in patients with maxillary constriction to provide skeletal expansion, correct posterior crossbite and resolve naso-respiratory problems by reducing oral respiration.The aim of this randomized controlled trial was to evaluate the effects of tooth-borne, tooth tissue-borne and bone-borne RME appliances on sleep quality with polygraphy. The null hypothesis was that there is no difference for the sleep quality between the appliances.

NCT ID: NCT04599803 Completed - Clinical trials for Obstructive Sleep Apnea of Adult

Baseline Sleep Apnea Study #2

Start date: July 8, 2020
Phase: N/A
Study type: Interventional

This is a single group, unblinded, prospective clinical study. This study seeks to understand patient diagnostic and treatment journey and positive airway pressure (PAP) therapy compliance for Verily Sleep Apnea (VSA) program/app users. Participants will enroll remotely and may undergo a home sleep test (HST). Upon confirmation of obstructive sleep apnea (OSA) and prescription of PAP therapy, the participant will begin using the VSA app to supplement PAP treatment. After 90 days of active participation, the participant will be given instructions for follow-up care, as indicated.

Nebula Study - Screener Apps and HSAT vs. PSG Comparison

Start date: October 27, 2020
Phase: N/A
Study type: Interventional

This is a prospective, unblinded, open-label, single group study. All subjects will undergo concurrent screener app, HSAT testing, and in-lab polysomnography.

NCT ID: NCT04581798 Completed - Clinical trials for Periodontal Diseases

Periodontal Disease in Patients With Obstructive Sleep Apnea

Start date: April 12, 2021
Phase:
Study type: Observational

Investigators hypothesize that in patients with obstructive sleep apnea (OSA) the severity of periodontal disease is significantly higher compared to patients without OSA in every aspect, including PI, PD, CAL and BOP. The number of lost teeth is hypothesized to be also higher in patients with obstructive sleep apnea. Purpose: evaluation of periodontal status in patients with obstructive sleep apnea. An analytical cross-sectional study will be conducted at the Department of Therapeutic Dentistry of the Sechenov University, Moscow. Investigators are planning to recruit 100 patients: 1) patients with OSA confirmed by polysomnography -75 participants aged between 35 and 65; 2) patients without OSA -25 participants of a similar age. Patients with obstructive sleep apnea syndrome will be sub-divided into three sub-groups according to OSA severity: 2A group - patients with mild apnea severity; 2B group - patients with medium apnea severity; 2C group - patients with severe apnea. All participants will undergo a dental examination including the following parameters: plaque index (PI; Silness & Loe, 1964), bleeding on probing (BOP), and touch depth of the pocket (PD), the level of clinical attachment loss (CAL). Investigators will also evaluate the number of lost teeth.

NCT ID: NCT04549324 Completed - Sleep Apnea Clinical Trials

Sleep Apnea, Coronary Atherosclerosis and Heart Failure in Diabetes Patients With Nephropathy

SLEEP
Start date: October 1, 2020
Phase:
Study type: Observational

Background: Diabetes, and especially diabetic kidney disease is associated with the development of cardiovascular disease such as calcification in the coronary arteries and heart failure. Sleep apnea is frequent among patients with diabetes and diabetic kidney disease and sleep apnea itself is a solitary risk factor in the development of cardiovascular disease. Nonetheless, sleep apnea is underdiagnosed in diabetes patients because of a discrepancy between sleep apnea severity and actual oxygen deficiency symptoms which makes the diagnosis difficult. For that reason, many diabetics have undiagnosed sleep apnea together with cardiovascular disease. Early discovery of sleep apnea among high risk diabetic patients may therefore be considered crucial before cardiovascular complications develop. For this reason, sleep apnea screening of high-risk diabetics can possibly improve early diagnostics of cardiovascular disease. Aim: This study will seek to establish the association between obstructive sleep apnea (OSA) and coronary calcification and heart failure in patients with diabetic kidney disease. The basic hypothesis of the study is that patients with diabetic kidney disease and concurrent OSA have a higher prevalence and severity of coronary calcification and heart failure compared to patients without OSA. Methods: Diabetic adult patients with scheduled check-ups at Steno Diabetes Center Aarhus, or Department of Renal Medicine on Aarhus University Hospital will be included in the study. Firstly, all included patients are screened for sleep apnea with the devices SomnoTouch® and ApneaLink®. Based on the sleep apnea determination; 40 patients with moderate-severe sleep apnea are compared with 40 patients without sleep apnea. In both groups, the patients are examined for calcification in the coronary vessels using a CT-scan while the function of the heart is examined by ultrasound (echocardiography). The stiffness of aorta is measured and performed using radial artery tonometry (SphygmoCor®). Furthermore, range of blood- and urine samples will be performed The perspectives are that patients with diabetes should be regularly evaluated for sleep apnea and that patients with moderate/severe sleep apnea should undergo further examination for cardiovascular disease even though the patients don't display any symptoms of either cardiovascular disease or sleep apnea.
