Filter by: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.
Overnight rostral fluid shift is one of the contributing factors for worsening obstructive sleep apnoea (OSA). Fluid shift has been recognized to play a role in the pathophysiology of sleep apnoea. Previous studies shown that fluid from the leg redistributes to the neck at night increases the neck circumference, hence indicating fluid accumulation in the neck. OSA patients are more susceptible to developing upper airway narrowing in response to fluid shift from the leg to the head and neck region. Previous studies were mainly done on Caucasian patients. The pathophysiology of OSA in Caucasian patients and Asian patients are different but both suffer a similar degree of OSA. The investigators would like to investigate if reducing leg swelling by a simple non-invasive intervention of wearing compression stocking during the day can attenuate sleep apnoea, and whether compression stocking is generally acceptable and well-tolerated among the general OSA population in Asia.
This is a randomized, double blind, 2-period, non placebo-controlled crossover study in patients with moderate to severe OSA and controlled hypertension, comparing atomoxetine with AD113
The objective of the study is to define an optimal threshold of the SEMSA-15 scale for obstructive sleep apnea (OSA) perception in patients with OSA to predict 3-month and 1-year continuous positive airway pressure adherence.
Breathing is one of the body's vital functions that occur under normal conditions using the nose. When humans breathe primarily through the mouth instead of the nose, this is referred to as mouth breathing. Snoring and obstructive sleep apnea (OSA) occur frequently in mouth breathers. Mouth breathing impairs oral health, reduces quantity and quality of saliva, and increases dry mouth, risk of developing dental caries, gingival inflammation, bad breath and dry lips. Serious health conditions associated with an obstructed upper airway in those who snore include hypertension, cardiovascular disease and mild cognitive impairment. Oral appliances (OAs) that bring the lower jaw (mandible) forward have been shown to be highly effective in reducing snoring and interruptions in breathing (respiratory events) that occur in those who snore and/or have OSA. The myTAP™ OA (AMI, Dallas, TX) includes an optional mouth shield (MS) that is anticipated to promote nasal breathing. The purpose of this study is to investigate the effects of oral appliance plus mouth shield therapy on sleep cardio-respiratory dynamics (breathing and heart activity) and their effect on improving OSA and oral health, especially of the periodontal tissues, in confirmed mouth breathers who snore and/or have OSA. As many as 70 adults at least 18 years old will be recruited to participate. All participants will wear the OA during sleep for 8 weeks (Phase 1). Half of the participants will be randomly assigned to wear the OA only for the first 4 weeks; all will wear both the OA and MS for the last 4 weeks. Participants will wear an easy-to-use home sleep recording system (NOX T3) for 2 nights at the start of the study and again at 4 weeks and 8 weeks. Based on the investigators' experience, some participants will not have achieved maximal benefit from the OA at 8 weeks, and will require addition adjustment. These participants will enter a second phase of the study where they will have 1 or more sleep studies done at 2 week intervals, and will further adjust their OAs (that is, advance the mandible) to eliminate snoring.
Obstructive sleep apnea (OSA) is a highly prevalent and morbid sleep disorder. Among the factors associated with its pathophysiology, the role of intermittent hypoxia stands out, contributing to the development of oxidative stress and inflammation. It is known that cumulative levels of these factors negatively influence the final portion of the DNA, known as telomere. In this sense, the investigators hypothesize that OSA is capable of accelerating aging process through telomere shortening mediated by inflammatory and oxidative markers. Thus, the aim of this study is to investigate the effect of OSA and its treatment with CPAP on the variation of telomere length and their associated mechanisms. For this, a randomized, double-blind, sham-controlled clinical study with 6 months duration will be conducted. We will recruit male participants with OSA diagnosis (apnea-hypopnea indexe15/hour), aged between 35-65 years and body mass index<35 kg/m2, which will be randomized to use CPAP or sham-CPAP for 6 months. Participants will visit the laboratory 7 times (baseline and after 1, 2, 3, 4, 5 and 6 months) and will be submitted to clinical and otorhinolaryngological evaluation, sleep questionnaires, polysomnography and blood collection for DNA and extraction and measurement of telomere length, as well as the expression of telomerase and oxidative and inflammatory markers (ADMA, homocysteine, cysteine, TBARS, 8-oxodG, TNF-a, IL-6 and IL-10). This project aims to contribute to the elucidation of the effect of OSA on telomere length maintenance, as well as the adjacent mechanisms to this relationship.
BAY2586116 is a new drug in development for the treatment of obstructive sleep apnea. This is a condition that causes breathing to repeatedly stop and start during sleep due to blocked upper airways. This is a study to learn more how safe BAY2586116 is, how it affects the body, how it moves into, through and out of the body in healthy Japanese male participants. The participants will be randomly chosen to receive 1 of 3 different doses of BAY2586116 or to receive a placebo. A placebo looks like a treatment but does not have any medicine in it. The participants will receive their study treatment either 1 single time or once a day for 5 days through a nasal spray. The participants will be in the study for a total of about 12 weeks. They will stay at their study site for either 5 or 9 days, depending on which study treatment they receive. During this time, the doctors will take blood and urine samples and check the participants' health. About 6 to 8 days after the participants receive their last treatment, the researchers will check the participants' health again. The main aim of this study is to learn more about how safe BAY2586116 is compared to the placebo. To answer this question, the researchers will count the number of participants who have medical problems that may or may not be related to the study treatment. These medical problems are also known as "adverse events" while they are in the study.
Wireless telemonitoring is compared with regular nursing procedure in terms of patient satisfaction, adherence to continuous positive pressure (CPAP) treatment and nursing time during the habituation phase of the CPAP therapy in obstructive sleep apnea syndrome (OSAS).
We aimed to investigate the relationship between obstructive sleep apnea (OSA) risk and respiratory inflammation evaluated by the exhaled breath condensate （EBC）interleukin-6 IL-6 and plasma SP-D, based on the Berlin questionnaire (BQ) screening values in an adult, urban community in Beijing, China. Volunteers aged >40 years were recruited from the Shichahai community of central Beijing. Their general information and disease history were recorded. OSA risk was assessed using the BQ. IL-6 in EBC and plasma SP-D were detected by enzyme-linked immunoassay (ELISA)through specimens collected on fasting. The differences in IL-6 and SP-D contents between high-risk and low-risk groups for OSA were compared, and the factors affecting their contents were analyzed.
It is a prospective, single center, single-arm clinical study to enroll a maximum of 25 subjects.
