The Role of Sub-mental Ultrasonography in Diagnosing Obstructive Sleep Apnea and Its Correlation With Subjective Scales

Start date: February 11, 2019
Phase:
Study type: Observational

The investigators hypothesize that sub-mental ultrasonography measures are strongly correlated with the severity of Obstructive Sleep Apnea Syndrome and the related specific subjective scales.

NCT ID: NCT03829956 Recruiting - Clinical trials for Obstructive Sleep Apnea

Intraoral Tongue Stimulation for Treatment of Primary Snoring

Start date: April 1, 2018
Phase: N/A
Study type: Interventional

Intraoral Neuromuscular Training for Treatment of Snoring Objective Studies show that improving pharyngeal muscle tone can ameliorate obstructive sleep apnoea (OSA) and snoring. The study uses an intra-oral stimulation device (SnooZeal) aimed at a population of snorers. The aim of this study is to assess the efficacy of intra-oral neuromuscular stimulation training during wakefulness on snoring. Methods This is a prospective study, recruiting 55 patients from the sleep clinics. In this study, subjects will use the intra-oral stimulation device once a day for 20 minutes each time for a period of 6 weeks. During these 6 weeks, subjects will complete a daily diary of the device use and any side effects or adverse events. Partners also complete a daily snoring score. Subjects will be followed-up for a further 2 weeks after treatment. They will complete Pittsburgh Sleep Quality Index (PSQI) and subjective sleep quality questionnaires for a further 2 weeks. Partners will also complete the post treatment snoring scores. Sleep study will be repeated. Outcome measures The objective evaluation will be based on pre- and post-treatment sleep studies, visual analogue scale (VAS) snoring scores, PSQI and subjective sleep quality questionnaire. All side effects and adverse events will be reported and acted upon according to the risk management structure.

Effect of Longitudinal Sleep Monitoring on Diagnosis and Treatment Decision in Patients With Suspected Obstructive Sleep Apnea

ELSA
Start date: February 1, 2019
Phase:
Study type: Observational

Obstructive sleep apnea (OSA) is a highly prevalent sleep-disordered breathing disease, caused by recurrent episodes of partial or complete collapse of the upper airway during sleep, resulting in intermittent hypoxia, fragmented sleep, fluctuations in blood pressure, and increased sympathetic nervous system activity. A single-night sleep study (i.e. respiratory polygraphy or polysomnography) is currently considered to be the gold standard for diagnosing OSA. However, recent studies suggest a significant intra-individual night-to-night variability of respiratory events, leading to the hypothesis that one single-night study might not reflect an accurate picture of the disease. Part A: Patients with suspected obstructive sleep apnea, referred to our clinic, undergo the regular diagnostic procedure recommended by the current guidelines. In addition to the in-hospital single-night sleep study, these patients will perform 14 nights of pulse-oximetry at home. By computing and analysing sensitivity and specificity of every additional night, the investigator will answer the questions how many nights of sleep monitoring by home oximetry are necessary to diagnose OSA reliably, and how longitudinal sleep monitoring could reduce the number of false-negative and false- positive results compared to the in-hospital single-night study. Part B: Based on the patients' data of part A, the investigator will develop a questionnaire and present anonymized cases to experts in the field of sleep medicine. Thereby, the investigator will evaluate if the additional information of repeated nocturnal pulse-oximetries changes the experts' decision making regarding diagnosis and treatment of OSA. In a second step, the investigator will perform a classical Delphi study with a panel of experts in sleep medicine to establish consensus on repeated sleep studies and how they should be used for diagnosis and treatment in patients with suspected OSA.

Validation of a Simplified MATRx Plus

Start date: March 1, 2019
Phase:
Study type: Observational

Sleep apnea (OSA) is a condition in which the air passage in the throat closes or partly closes during sleep and repeatedly interrupts breathing. The standard treatment for sleep apnea is continuous positive airway pressure (CPAP), but it is not suitable for all patients. Another treatment is to use an oral appliance in your mouth when you sleep. The appliance covers the upper and lower teeth and acts to pull the lower jaw forward, opening the throat passage and allowing normal breathing. Oral appliance therapy does not treat sleep apnea effectively in everyone. In order to identify the people in whom oral appliance therapy will work, Zephyr Sleep Technologies has invented a feedback-controlled device that tests various positions of the lower jaw. This commercially available device, known as MATRx plus, is a Health Canada approved and FDA cleared motorized dental positioner that can be used in an overnight sleep study performed in the home. Temporary dental impression trays cover your upper and lower teeth. These are attached to a small motor that slowly and gently pulls your lower jaw forward under the control of a computer in response to real-time breathing events. The commercial MATRx plus device uses measures of airflow from a nasal cannula and blood oxygen saturation from a pulse oximeter to guide the movement of the lower jaw during the test. Though the test is accurate, the equipment can be somewhat cumbersome to apply. The purpose of the study is to validate a simplified version of the test that requires fewer sensors and sleep time.

Association Between Obstructive Sleep Apnea and Bruxism

Start date: March 1, 2019
Phase:
Study type: Observational

The objective of this retrospective observational study will be to investigate the between the Obstructive Sleep Apnea Syndrome (OSAS) and Sleep Bruxism (SB), in individuals diagnosed through polysomnography (PSG).

NCT ID: NCT03804827 Not yet recruiting - Clinical trials for Obstructive Sleep Apnea

Sleep Disordered Breathing in Acute Congestive Heart Failure

Start date: January 14, 2019
Phase:
Study type: Observational

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.

Global Self-management Telematic Support for Patients With Obstructive Sleep Apnea.

TELESAS
Start date: March 2019
Phase: N/A
Study type: Interventional

This clinical trial compares the usual follow-up to a program of telematic control and self-management in a group of patients with severe obstructive sleep apnea-hypopnea syndrome (OSAHS), few symptoms and treated with continuous positive airway pressure (CPAP). The objective of the intervention is to achieve a CPAP compliance of ≥4 hours per day in at least 90% of the subjects.
