Filter by:This proof-of-concept study is being performed to evaluate whether the hypoglossal nerve can be stimulated using a small series of electrodes placed surgically via a percutaneous approach. Minimally invasive off the shelf medical devices will be used and observation of the characteristic physiological responses to stimulation of the HGN, will be assessed.
Sleep is an important factor that influences long-term quality of life with known health consequences. Obstructive sleep apnea, the most prevalent disease that disturbs sleep, is considered a public health problem. Treatment with continuous positive airway pressure is cost effective and reverses the clinical consequences but there is a percentage of patients who do not tolerate it or leave it without treatment and with potential future health complications. Mandibular advancement device can be a valid and well tolerated alternative, it is known that it reduces apnea-hypopnea index, but its effect on the improvement of sleep quality is evaluated by polysomnography that interferes with the quality of sleep. There is an ambulatory monitoring device for sleep quality and circadian rhythms, which can register prolonged periods of time, under natural conditions and at a lower cost than a polysomnography. This pilot project assesses whether mandibular advancement device is an effective and well tolerated alternative in the treatment of obstructive sleep apnea to improve the quality of life and sleep in the medium and long term.
Obstructive Sleep Apnea (OSA) remains underdiagnosed in 2022, as a result of the unawareness of its serious health-related consequences and the lack of diagnosis accessibility. Respiratory polygraphy (PV) is widely used as a screening tool and sometimes a diagnosis test, although polysomnography (PSG) remains the gold standard investigation as it provides complete information about sleep architecture and arousals. Thus, it has been shown that the Apnea Hypopnea Index (AHI) and Respiratory Disorder Index (RDI) are underestimated by PV vs PSG. Approaches to substitute PSG by simpler but equally efficient diagnosis tests have included devices aiming to record complementary signals and to analyze them with Artificial Intelligence. In this context, ASEEGA algorithm has demonstrated its performance for automatic sleep scoring in healthy individuals and patients with various sleep disorders, based on a single channel EEG analysis. This study aims at comparing the real-life performance and feasibility of added single channel EEG automatic sleep scoring using ASEEGA to PV versus standard PV and PSG in adults referred to a regional sleep reference center for suspected OSA. We hypothesize that this approach (1) is as accurate as PSG and more accurate that PV for AHI analysis, and (2) is less time-consuming than PSG.
This clinical investigation is designed to assess the F&P Toffee Nasal and Toffee Nasal Pillows masks in home for use during PAP therapy delivery. The objectives of the investigation are to assess therapeutic efficacy, safety and comfort.
The purpose of the study is to examine the feasibility, acceptability, and initial outcomes of clinical decision support (CDS) and a Sleep Navigation program to enhance primary to specialty care management of pediatric sleep-disordered breathing (SDB).
Obstructive sleep apnea (OSA) is a sleep disorder which is caused because of collapse of airway or inappropriate tongue position. As OSA becomes severe, the physical and psychological aspect might be influenced due to insomnia. In addition, many evidences revealed that OSA is related to cardiovascular disorder. Apnea-hypopnea index (AHI) and epworth sleepiness scale (ESS) are common parameters to evaluate the severity of OSA. Recently, body and tongue fat have certain relation with OSA, and the higher the fat, the more possible to get OSA. To find the treatments for OSA, myotherapy has been proved to improve AHI and ESS. The treat mechanism is speculated that increasing muscle tone around oral and oropharyngeal and decreasing tongue fat. High intensity interval training (HIIT) might be effective to OSA, for it could lower down the total body fat. Furthermore, HIIT is a time-efficient program which can increase exercise adherence. Last, less articles discussed about the effect of supervised verse unsupervised treatment and the effect of mix-model treatment. The purpose of the study is investigating the comparison between supervised HIIT plus myotherapy and unsupervised home exercise plus myotherapy. Method: 40 patients who meets the inclusion criteria will be recruited in this article during 2022/01 to 2022/12. Then, they will be randomly assigned into HIIT plus myotherapy group and home exercise plus myotherapy group. The treatment process will last for 8 weeks. All the outcomes such as AHI,ESS and body fat will be completed before and after 8 weeks treatment. The Wilcox signed test was adopted to analyze the treatment before and after the treatment sessions (time effect). The Mann-Whitney U was applied for the difference before and after treatment between two groups (group effect), and the baseline of two groups was also analyzed by this method. The significant level was set as p value< 0.05. Hypothesis: It is speculated that HIIT plus myotherapy might revealed better outcomes on AHI, ESS, and body fat.
The effect of CPAP on weight and fluid homeostasis will be assessed. Obstructive sleep apnea treatment-naive subjects will randomized to CPAP and control groups. Weight change, and changes in overnight urinary volume, intra and extracelullar volume, plasmatic B-type natriuretic peptide (BNP) and antidiuretic hormone (ADH) and urinary osmolality will be compared between groups.
Expiratory pressure relief (EPR) is a technology designed to improve patient comfort during continous positive airway pressure (CPAP) treatment for obstructive sleep apnea (OSA). The investigators hypothesized that the use of CPAP with EPR is less effective in controlling OSA when compared to CPAP without EPR, applied at the same treatment pressure. The investigators also hypothesized that the CPAP pressure necessary to abolish respiratory events during both manual and automatic CPAP titration with EPR will be greater than the pressure titrated with CPAP without EPR. OSA participants will undergo full polysomnography during CPAP and EPR will be turned on and off in order to test the impact of EPR on airflow and residual AHI.
The objective of this study is to assess the efficacy of the eXciteOSA device amongst a sample of patients with mild OSA. The study is a multi-center, prospective, open-label, randomized, parallel-arm trial of eXciteOSA versus no-therapy for six weeks. Up to 200 participants will be enrolled, in order to randomized n=102.
The purpose of this study is to prospectively compare the effectiveness of a novel personalized approach to the surgical treatment of obstructive sleep apnea (OSA) in children, drug induced sleep endoscopy (DISE) directed surgery versus the standard adenotonsillectomy (AT). This will also serve to test the feasibility of recruiting families for a future randomized protocol comparing the same surgical techniques. It is the investigators' central hypothesis that a personalized DISE-directed surgical approach that uses existing procedures to address the specific fixed and dynamic anatomic features causing obstruction (ie, anatomic endotypes) in each child with small tonsils or Down syndrome will be superior to the currently recommended standard first line approach of AT. This novel approach may improve OSA outcomes and reduce the burden of unnecessary AT or secondary surgery for persistent OSA after an ineffective AT. To test this hypothesis, the investigators will study children aged 2 to 18 years with clinically small tonsils (Brodsky score 1+ or 2+ on a scale 1+ to 4+) OR Down syndrome.
