Active clinical trials for "Apnea"

Test the effect of added a single-use Varnum mouthpiece on pharyngeal collapsibility and obstructive sleep apnea (OSA) severity in patients who identify themselves as mouth breathers. Research indicates that nasal breathing not only may improve sleep apnea but it also increases circulation, blood oxygen, and carbon dioxide levels, slows the breathing rate, and improves overall lung volumes. Thus, the investigators will test whether a single-use Varnum mouthpiece can improve pharyngeal collapsibility and OSA severity in mouth breathers.

Purpose of Study: Apnea of Prematurity (AOP) is common, affecting the majority of infants born <34 weeks gestational age (GA). Apnea is accompanied by intermittent hypoxia (IH), which contributes to multiple pathologies, including retinopathy of prematurity (ROP), sympathetic ganglia injury, impaired pancreatic islet cell and bone development, and neurodevelopmental disabilities. Standard of care for AOP/IH includes prone positioning, positive pressure ventilation, and caffeine therapy, none of which is optimal. The objective is to support breathing in premature infants by using a simple, non-invasive vibratory device placed over limb proprioceptor fibers, an intervention using the principle that limb movements facilitate breathing. Methods Used: Premature infants (23-34 wks GA) with clinical evidence of AOP/IH were enrolled 1 week after birth. Caffeine therapy was not a reason for exclusion. Small vibration devices were placed on one hand and one foot and activated in a 6 hour ON/OFF sequence for a total of 24 hours. Heart rate, respiratory rate, oxygen saturation (SpO2), and breathing pauses were continuously collected.

The researchers in this study want to learn how drug BAY2586116 works in patients with obstructive sleep apnea (OSA). OSA is a sleep disorder marked by breathing pauses during sleep due to repetitive obstructions of the upper airway. BAY2586116 is a new drug under development for the treatment of OSA. It blocks protein channels expressed on the surface of the upper airways in small mechanoreceptors (a type of molecule that sense and pass stimulus outside a cell on to the inside of the cell through mechanical gate on the surface of the cell). Thus, the negative pressure reflex alerting the brain of inspiration is triggered more easily leading to a stronger activation of throat muscles. This prevents narrowing or collapse of the upper airways during sleep which is one of the pathological key factors in OSA. Researchers will study the effects of different routes of administration (drops into the nose, spray into the nose or throat or spray into the throat by endoscopy). Endoscopy allows the doctor to look at areas in the throat that cannot be seen with a mirror: a thin tube-like instrument is inserted through the nose to check and give the medication. Different doses of the test drug will be given. They also want to find out if participants experience any medical problems during the study. Patients participating in this study will undergo three study parts. After completing Part A and Part B, participants will be asked to join Part C. In Part A, participants will receive both the test drug and placebo (a placebo looks like the test drug but does not have any medicine in it); in Part B, participants will receive the test drug twice via different routes of administration (drops in nose and spray in nose or throat) and in Part C, the participants would receive the test drug once via spray in throat by endoscopy. The sleep of the participants will be monitored by medical equipment. Participants will be asked to visit the clinic 7 times in 14 weeks in total.

This is a randomized, 3-period, placebo-controlled, crossover study to examine the efficacy and safety of AD182 and AD504 versus placebo in patients with obstructive sleep apnea.

The aim of this study is to assess the efficacy of transcutaneous electrical stimulation of the upper airway muscles in patients with obstructive sleep apnea.

To study the effects of two combination therapies for patients with obstructive sleep apnea (OSA) who have been both intolerant to Positive Airway Pressure (PAP) therapy and sub-therapeutic to oral appliance therapy. Hypothesis 1. There is a difference between Continuous Positive Airway Pressure (CPAP) vs CPAP/Oral Appliance (OA) connect vs CPAP/OA disconnected in terms of: Apnea Hypopnea Index (AHI) reduction Amount of side effects Amount of Leaks Hours of use (compliance) CPAP pressure 2. There is a difference between connected and disconnected for the following symptoms: Epworth sleepiness Scale (ESS) Functional Outcomes of Sleep Questionnaire (FOSQ) Side effects Study Design - randomized prospective parallel

The primary objective of the PLUTO study is to evaluate the safety and tolerability of the ZENS transcutaneous nerve stimulator device in primary snorers and those with mild obstructive sleep apnea. The study will assess the impact of ZENS on snoring frequency, duration, and other relevant sleep parameters. The intended purpose of the investigational device is to deliver a transcutaneous electrical stimulation signal to the hypoglossal nerve in the "ON" phase in order to alter the apnea hypopnea index (AHI), as well as mean snoring burden (intensity, duration), and to deliver no signal in the "OFF" phase of the study as a means for comparison. Subjects utilizing the ZENS Device will experience a reduction in snoring during the "ON" versus "OFF" phase, as quantified by a reduction in the percentage of time per hour of snoring (≥40 dB) in the active ZENS Device ("ON" phase) versus the inactive ZENS Device ("OFF" phase).

Efficacy of Pure Prone Positioning (PPP) treatment in improving apnea-hypopnea index (AHI) and nocturnal oxygen saturation was investigated in mild to moderate Obstructive Sleep Apnea.

The objective of the study is to determine the safety and preliminary efficacy in patients utilizing the aura6000 System for the treatment of Obstructive Sleep Apnea (OSA).

Adipocyte fatty acid binding protein (A-FABP) is a member of the FABP super family, is abundant in adipocytes and macrophages. Regulatory functions of A-FABP in lipid and glucose metabolism have been described, and it is suggested to play an important role in the pathogenesis of metabolic syndrome.We hypothesize that obstructive sleep apnea (OSA) may upregulate A-FABP production and thus causally contribute to metabolic dysfunction. Our group has recently demonstrated that A-FABP, expressed and secreted from adipocytes, is present in the blood stream .The levels of A-FABP correlated with various metabolic variates in the metabolic syndrome. Furthermore, we have obtained novel data in men with a range of sleep disordered breathing showed that the duration of oxygen desaturation correlated with circulating levels of A-FABP, independent of age and waist/body mass index. The current proposal aims to pursue this finding and further explore the role of A-FABP in the association of OSA and metabolic dysfunction.
