Filter by:To create a validated computational tool to predict surgical outcomes for pediatric patients with obstructive sleep apnea (OSA). The first line of treatment for children with OSA is to remove their tonsils and adenoids; however, these surgeries do not always cure the patient. Another treatment, continuous positive airway pressure (CPAP) is only tolerated by 50% of children. Therefore, many children undergo surgical interventions aimed at soft tissue structures surrounding the airway, such as tonsils, tongue, and soft palate, and/or the bony structures of the face. However, the success rates of these surgeries is surprisingly low. Therefore, there a need for a tool to improve the efficacy and predict which surgical option is going to benefit each individual patient most effectively. Computational fluid dynamics (CFD) simulations of respiratory airflow in the upper airways can provide this predictive tool, allowing the effects of various surgical options to be compared virtually and the option most likely to improve the patient's condition to be chosen. Previous CFD simulations have been unable to provide information about OSA as they were based on rigid geometries, or did not include neuromuscular motion, a key component in OSA. This project uses real-time magnetic resonance imaging (MRI) to provide the anatomy and motion of the airway to the CFD simulation, meaning that the exact in vivo motion is modeled for the first time. Furthermore, since the modeling is based on MRI, a modality which does not use ionizing radiation, it is suitable for longitudinal assessment of patients before and after surgical procedures. In vivo validation of these models will be achieved for the first time through comparison of CFD-based airflow velocity fields with those generated by phase-contrast MRI of inhaled hyperpolarized 129Xe gas. This research is based on data obtained from sleep MRIs achieved with the subject under sedation. While sedating the patient post-operatively is slightly more than minimal risk, the potential benefits to each patient outweigh this risk. As 58% of patients have persistent OSA postsurgery and the average trajectory of OSA severity is an increase over time, post-operative imaging and modeling can benefit the patient by identifying the changes to the airway made during surgery and which anatomy should be targeted in future treatments.
Cheeks appearance is a screening tool developed based on cheeks observation to identify volume, flaccidity or both to predict people with probable obstructive sleep apnea.
This study aims to evaluate the efficacy of an endoluminal gastric plication using an endoluminal-suturing device to improve severe OSAS in patients with a BMI above or equal to 28 kg/m² until 34.9kg/m².
The purpose of this research is to assess how well people with mild obstructive sleep apnea (OSA) adhere to the eXciteOSA device and specifically examine whether adherence of the device is different with low versus high electrical stimulation. In addition, this research study will assess how well the device affects mild sleep apnea and if it improves sleepiness and quality of life.
Chronic respiratory diseases such as obstructive sleep apnea syndrome (OSA) and chronic obstructive pulmonary disease (COPD) constitute a major public health problem, due to their high prevalence, but especially because of their cardiovascular and metabolic morbidity and mortality and the associated costs for the health system. The organization of long-term management of these diseases is now part of the e-health process, digital health with the use of massive "big data" generated by care and follow-up. Therapeutic patient education and the integration of connected objects will allow personalized therapeutic education support with interventions by local medical staff adapted to the needs of the patients. This will also allow to objectify the effect of treatments such as continuous positive airway pressure (CPAP) for OSA or non-invasive ventilation (NIV) and/or oxygen therapy for COPD, not only on the prevention of respiratory decompensation but also on cardiovascular and metabolic risk factors which are major elements of the prognosis. This project will therefore make it possible to demonstrate the feasibility and to deploy a multi-actor care pathway in the territory. The investigators propose a prospective clinical study, conducted at the Verdun Hospital, with the main objective of studying the evolution of the quality of life of patients with a chronic respiratory pathology, during an integrated management at home for 6 months. The secondary objectives: - To study the evolution of the following parameters, before treatment (at inclusion) and after 6 months of integrated management: 1. Treatment compliance (CPAP or NIV/oxygen therapy) 2. Physical activity 3. Weight 4. Mean arterial pressure 5. Oxygen saturation, heart rate and respiratory rate for COPD patients 6. Severity of COPD for the patients concerned 7. Daytime sleepiness 8. Fatigue 9. Patient acceptability of the use of connected objects - To analyze the trajectories of the measures collected throughout the integrated management to identify specific profiles. - To analyze the daily data of the different connected objects and treatments with regard to the patients' profiles (according to age, gender, comorbidities, OSA or COPD group).
The prevalence of obstructive sleep apnea (OSA) is a significantly higher in people after spinal cord injury (SCI) than in the general population. As a positive pressure therapy (CPAP) is often poorly tolerated, a mandibular advancement device (MAD) can be used for the treatment of OSA. The purpose of this study is to determine the efficacy of MAD in people with SCI and to verify their adherence to the therapy.
Multi-center, open-label, prospective, randomized clinical trial of the aura6000(R) System for the reduction of apnea and hypopneas in adult patients with moderate to severe obstructive sleep apnea who have failed or are unwilling to use positive airway pressure treatment.
Aims of this research are to detect if an improvement in sleep pattern in patients suffering from obstructive sleep apnea (OSA), produces a reduction in pain and dysfunction in the orofacial area by examining variation in temporo-mandibular disorder (TMD) signs and symptoms and if the prevalence of TMDs in OSA patients controlling this disease decreases to levels comparable to healthy subjects. 41 OSA patients will undergo a complete TMD examination prior to start any OSA treatment and after at least 18 months of therapy. Variations in TMD signs and symptoms will be recorded.
Obstructive Sleep Apnea Syndrome (OSA) is one of the most common chronic diseases and is associated with prognostic cardiovascular and metabolic co-morbidities. OSAS is the recurrence of complete (apnea) or partial (hypopnea) collapse of the upper airway during sleep resulting in sleep fragmentation and chronic intermittent hypoxia (ICH) which are the major determinants of cardiovascular and metabolic complications including type 2 diabetes, obesity and non-alcoholic fatty liver. These comorbidities are associated with a change in intestinal microbial ecology. In most cases, there is a reduction in bacterial genetic diversity and more or less specific signatures of cardiovascular and metabolic diseases, making it possible to envisage personalized and innovative therapeutic treatments. In animals exposed to intermittent hypoxia, there is local hypoxia that increases intestinal permeability, produces a reduction in microbiota diversity and favors microbial species that are at the origin of pro-inflammatory factors. Continuous Positive Airway Pressure (CPAP) is the standard treatment for OSA. Its effect on the intestinal microbiota has not yet been evaluated.
This research aims to provide pediatric patients with polysomnography (a sleep study) before and after orthodontic treatment to determine if the extraction of upper premolars for treating excessive overjet results in an increase of the AHI (Apnea Hypopnea Index) compared to similar patients treated without upper premolar extractions.
