NCT ID: NCT04752462 Recruiting - Clinical trials for Obstructive Sleep Apnea

Motivational Enhancement - Acute Decompensated Heart Failure and OSA

Start date: May 13, 2021
Phase: N/A
Study type: Interventional

A feasibility randomized controlled trial will be conducted with a 6-month follow up to: Examine the impact of early intensive telemedicine motivational enhancement (TIME) vs standard of care on PAP adherence (n=40/group) and continuity of care at 3 and 6 months post-discharge in patients admitted with ADHF with a new inpatient diagnosis of OSA(REI>5). Assess the effect of early telemedicine integrated with motivational enhancement (TIME) vs standard of care on patient reported outcomes including Functional Outcomes of Sleep questionnaire (FOSQ-10), Kansas City Cardiomyopathy Questionnaire (KCCQ-12). Investigate the impact of early TIME vs standard of care on 6-month hospital readmissions.

NCT ID: NCT04743752 Recruiting - Clinical trials for Non-small Cell Lung Cancer

Obstructive Sleep Apnea Influences Efficacy of PD-1-Based Immunotherapy Against Non-Small Cell Lung Cancer

Start date: February 23, 2021
Phase:
Study type: Observational

This prospective, observational cohort study aims to explore the influence of obstructive sleep apnea(OSA) on the efficacy of PD-1-based immunotherapy in patients with non-small cell lung cancer(NSCLC). Patients who had no prior treatment for advanced NSCLC and are intended to receive PD-1/PD-L1 antibody will be recruited. According to sleep monitor results, participants will be divided into Group NSCLC and Group OSA+NSCLC. Primary outcome is the objective remission rate(ORR).

NCT ID: NCT04726982 Recruiting - Clinical trials for Obstructive Sleep Apnea

Optimal Dosage of Acetazolamide for OSA Treatment

Start date: April 20, 2021
Phase: Phase 4
Study type: Interventional

Acetazolamide, a carbonic anhydrase inhibitor, has received some attention as potential treatment for obstructive sleep apnea (OSA). It produces a metabolic acidosis by excreting bicarbonate, thereby stimulating baseline ventilation. Evidence suggests that acetazolamide primarily improves ventilatory control instability (expressed as loop gain), which is an important contributor to the pathophysiology of OSA. Few studies have assessed the efficacy of acetazolamide in patients with OSA. Since most of them had a small sample size and used different therapeutic dosages, clinical applications are currently limited. Therefore, this study aims to compare the effect of two acetazolamide dosages on the severity and pathophysiology of OSA.

NCT ID: NCT04675268 Recruiting - Clinical trials for Obstructive Sleep Apnea

Variability in Nocturnal Oxygen Parameters in Suspected Obstructive Sleep Apnea (OSA)

VARIOUS
Start date: January 26, 2021
Phase: N/A
Study type: Interventional

The investigators would like to evaluate the variability of oxygen (and PPG) parameters during 7 nights at home. Oxygen (and PPG) parameters will also be evaluated during 1 night at the hospital (diagnostic polysomnography). Based on currently developed algorithms, surrogate apnea-hypopnea index (AHI), cardiovascular status and the variability of these parameters will be evaluated.

NCT ID: NCT04659291 Recruiting - Clinical trials for Obstructive Sleep Apnea

Prospective Study on Patients With Obstructive Sleep Apnea in Hong Kong (PrOSA)

Start date: August 30, 2020
Phase:
Study type: Observational [Patient Registry]

Obstructive sleep apnea syndrome (OSAS) is a common disorder with prevalence rates of at least 4% among the middle-aged male Caucasians and Hong Kong (HK) Chinese populations. It is characterized by repetitive episodes of upper airway obstruction, causing intermittent hypoxia, sleep fragmentation, disabling daytime sleepiness, impaired cognitive function and poor health status. OSAS patients are at increased risks of non-fatal and fatal cardiovascular morbidity and mortality including sudden death, in addition to being more prone to road traffic accidents. However, there is no long term follow up of patients with OSAS on the incidence of cardiovascular disease, compliance on the therapy and the impact of the quality of life. The study is aimed to carry out a prospective observational study assessing the role of OSAS as a possible cause of increased cardiovascular risk and cognitive decline.

NCT ID: NCT04658290 Recruiting - Clinical trials for Obstructive Sleep Apnea

Prevalence of Obstructive Sleep Apnea (OSA) and the Association With Cognitive Impairment

Start date: August 29, 2020
Phase:
Study type: Observational

The study is aimed to carry out an epidemiology study investigating the prevalence of obstructive sleep apnea (OSA) and the association with cognitive impairment.

NCT ID: NCT04634786 Recruiting - Clinical trials for Obstructive Sleep Apnea

Association Between CRSA and OSA

CRSA
Start date: February 6, 2021
Phase:
Study type: Observational

This goal of this study is to know the association between the central serous chorioretinopathy and the obstructive sleep apnea. Many studies have been done in order to assess the association between the central serous chorioretinopathy and obstructive sleep apnea and the results are always controverses actually.

NCT ID: NCT04630535 Recruiting - Clinical trials for Obstructive Sleep Apnea

OSA as a Remote Ischemic Preconditioning in Vascular Surgery

Start date: November 1, 2020
Phase:
Study type: Observational

Ischemia and reperfusion (I/R) injury during abdominal aortic aneurysm (AAA) repair is inevitable and may lead to postoperative multi-organ failure. Remote ischemic preconditioning (short periods of ischemia in anticipation of longer period of ischemia) may act protectively against ischemia. Studies of ischemic preconditioning in patients with AAA are conflicting. Obstructive sleep apnea (OSA) is a sleep disordered breathing syndrome which may have a protective effect against ischemia. The investigators hypothesize that I/R injury will be less pronounced in patients who have OSA and that the extent of I/R injury will inversely correlate with OSA severity. Accordingly, the aim of this study is to compare postoperative complications and markers of I/R in patients undergoing elective AAA repair who do and do not have OSA.

NCT ID: NCT04623463 Recruiting - Clinical trials for Obstructive Sleep Apnea

Effects of Physical Activity on OSA Severity Based on the Level of Fluid Shift

AP-FLUID
Start date: October 20, 2020
Phase: N/A
Study type: Interventional

Obstructive sleep apnea (OSA) is characterized by complete or partial upper-airway collapse during sleep associated with sleepiness. OSA causes severe impairments in quality of life (sleepiness, tiredness, concentration difficulties). Moreover, OSA has adverse consequences on the cardiovascular system by causing intermittent hypoxia, increased sympathetic nervous system activation and vascular endothelial dysfunction. Continuous Positive Airway Pressure (CPAP) and mandibular advanced devices (MAD) remain the two first-line therapies for OSA. However, not all patients are eligible for these treatments or are not able to follow for a lifelong therapy and therefore do not use it consistently. A recent meta-analysis has confirmed that regular physical activity reduces OSA by approximately 28% (Mendelson et al. 2018). However, an important inter-individual variability exists and no study to date has identified characteristics of patients who respond to these interventions. The aim of this Prospective study, single-site, non-randomized 4-week trial is to evaluate the impact of a 4-week physical activity intervention on the apnea-hypopnea index (AHI) in OSA patients based on their baseline fluid shift level. Participants included in the present study will benefit from a 4-week physical activity intervention. Upon the initial visit, a physical activity prescription will be defined and they will be equipped with a physical activity monitor that allows feedback. Participants will then exercise one day per week on-site and 4 days/week on their own. Weekly physical activity will be reviewed weekly with the participant during their on-site visit.
