Obstructive sleep apnea syndrome (OSA) is defined by the association of clinical symptoms - drowsiness in particular - and sleep breathing disorders, objectified by measuring the apnea-hypopnea index (AHI). Apneas and hypopneas during sleep are responsible for micro-arousals and hypoxemia. In the short term, these result in daytime sleepiness with reduced alertness, difficulty driving and carrying out tasks (increased risk of road accidents and accidents at work), memory and concentration problems. , mood disorders. These disturbances lead to an impairment of the quality of life. In the long term, severe OSA (AHI > 30 events/hour) increases all-cause mortality and cardiovascular morbidity. The reference treatment is nasal ventilation by Continuous Positive Airway Pressure (CPAP). In practice, the observance and effectiveness of CPAP are limited by the sometimes difficult acceptance of cumbersome equipment, involving noise pollution and requiring the wearing of night-time equipment that some patients find difficult to bear. The alternative treatment is represented by the mandibular advancement orthosis . Lifestyle and dietary measures are always recommended. To date, no pharmacological treatment has demonstrated its effectiveness in OSA. Studies have shown that the antioxidant capacity of the blood is reduced in patients with OSA. It would be secondary to the cycles of hypoxia and reoxygenation which cause a modification of the oxidative balance, leading to an increase in free radicals. It has been observed that the serum levels of trace elements and heavy metals are higher during OSA, by deterioration of the balance of these substances due to oxidative stress and inflammation. Antioxidant therapies have reduced biomarkers of oxidative stress in apneic patients. A new path of research is opening up with the use of antioxidants and trace elements in OSA. To scientifically support the hypothesis of the action of these supplements based on trace metals on OSA, PRONUTRI wish to conduct a comparative, randomized, double-blind study versus placebo evaluating the effect of a specific complex of trace metals in the OSA.
This project evaluates the morphological predictive factors for prescribing a mandibular advancement device in the therapeutic approach of Obstructive sleep apnea (OSA). The investigators will carry out the project with patients who travel to CUF Tejo Hospital to solve their sleep disturbance, namely cases of obstructive sleep apnea. The investigators designed three groups of 22 individuals each. The investigators will only include individuals after signing the informed consent. In the 1st appointment, the principal investigator will conduct a complete anamnesis and a clinical examination, where several items will be documented: Age, gender, body mass index, mallampati index, neck, and waist circumference. The clinical interview will assess the patient's daytime sleepiness, nighttime snoring, and quality of life through the respective questionnaires: the Epworth Sleepiness Scale (ESS), the snoring severity scale (SSS), and the Sleep Apnea Quality of Life Index (SAQLI). Still, in the 1st consultation, a level III Polysomnography (PSG) will be prescribed to assess the possibility of OSA, and a pharyngeal computed tomography (CT) with cephalometric analysis and recording in maximum comfortable protrusion to evaluate the Upper Airway (UA) and the prognosis of mandibular advancement in case of UA collapse. The other group will perform Drug-Induced Sleep Endoscopy (DISE) and CT with registration in maximum comfortable protrusion. Then, the investigators will make personalized and titled mandibular advancement devices (MAD). The measurements and PSG III questionnaires will be carried out after 1 and 6 months to evaluate the results.
Video-polygraphy or video-polysomnography (vP(S)G) is the reference exam for the diagnosis of obstructive sleep apnea syndrome (OSAS) in children as it allows the detection of the respiratory events presented by the child during sleep. This exam requires a one-night hospitalization and several sensors installed on the child's body, sometimes not well-accepted in children. Portable oximetry is an easier test to perform, better accepted by the child, and gives the desaturation index that may be used for the diagnosis of OSAS because most respiratory events are associated with desaturations. The hypothesis of this study is that the desaturation index obtained by the oximetry performed at the same time with the v(P(S)G) can identify a moderate-severe OSAS in children.
The purpose of this study is to evaluate efficacy of mandibular advancement device (MAD). on treating obstructive sleep apneas, symptoms, Apnea/Hypopnea Index (QHI) and the Respiratory Arousal Index (AHI/REI) and peripheral capillary oxygen saturation (SpO2) Range, PULSE in patients with mild to moderate obstructive sleep apnea/hypopnea syndrome, and evaluating potential dental side effects
Currently, mandibular advancement devices (MAD) are recommended by the American Academy of Sleep Medicine (AASM) as the first treatment a line in cases of mild and moderate OSAS in patients without severe cardiovascular comorbidity and in severe OSAS when treatment with CPAP fails or is rejected. Although oral appliances (OD) have less impact on AHI reduction, both treatments have been shown to have a similar impact on clinical outcomes, including symptomatology and cardiovascular outcomes. In addition, MAD is a treatment that is better tolerated by patients, which results in greater compliance on their part, and therefore a similar efficacy in clinical practice. Its mechanism of action consists of maintaining the patency of the upper airway, preventing collapse. They act by correcting the anatomical imbalance of patients with OSAS, specifically stabilizing and increasing the space of the velopharyngeal airways, reducing their collapsibility. However, the effectiveness of the treatment of this pathology using MAD is limited by the inter-individual preference of the results of the treatment and the lack of information in the correct selection of the appropriate patients. In fact, oral appliances are an effective treatment for 60-70% of patients. Therefore, the precise selection of patients is essential to optimize the results of MAD treatment and thus avoid the necessary costs. This justifies the need to identify phenotypes likely to predict response to MAD treatment.
Obstructive Sleep Apnea Syndrome (OSAS) in children is a significant public health problem whose clinical diagnosis is not specific. The recording of sleep and breathing (polysomnography, PSG) is the reference exam. PSG consists in installing on the child's body electrodes necessary to determine the sleep stages and sensors used to determine the presence of respiratory events during sleep. At-home PSG, compared to hospital PSG, improves sleep quality. PSG is yet an anxious exam due to the multitude of electrodes and sensors. Ventilatory polygraphy (PG) consists of installing only respiratory detectors. The objective of this study is to demonstrate that at-home PG has the same diagnostic value as at-home PSG.
The intended use of the Positive Airway Pressure (PAP) Problems Triaging Tool (TT) is to appropriately triage patients with a PAP-associated problem(s) to a specific intervention(s) based on patient responses. Thus, the proposed research will validate the tool, determine optimal scoring thresholds, and explore the utility of the tool as an indicator for intervention. Our central hypothesis is that the PAP Problems TT will identify treatment barriers that if unaddressed, are predictive of treatment non-adherence.
Serious mental illnesses (SMI) like schizophrenia and bipolar disorder are two of the most disabling and costly chronic illnesses worldwide. A high proportion of adults with schizophrenia and bipolar disorder have sleep disorders, like obstructive sleep apnea (OSA), but tend to be underdiagnosed and undertreated compared to the general population. This study aims to examine feasibility, acceptance, and impact of OSA treatment and how it affects cognitive function in people with SMI.
