Filter by:Obstructive sleep apnea (OSA) is an extremely common disease with inadequately explored neurocognitive consequences. The investigators will study OSA patients before and after treatment to understand how OSA changes decision making abilities, and whether treatment can reverse such cognitive changes. These results could provide deeper insight into how OSA affects decision making either temporarily or permanently, and provide another rationale or motivation for treatment of OSA in adults.
The current study combines two treatments for obstructive sleep apnea (OSA), oral appliances and supplemental inspired oxygen. The following aims will be tested: Aim 1. To determine whether supplemental inspired oxygen further reduces OSA severity (apnea-hypopnea index) in patients using an oral appliance. Aim 2. To determine whether baseline OSA phenotypes can predict the efficacy of oral appliances versus supplemental oxygen versus both treatments in combination. We will test whether responders to oral appliances have distinct pathophysiological characteristics compared with oxygen responders.
The purpose of this project is to determine whether obstructive sleep apnea (OSA) treatment with positive airway pressure therapy (CPAP) can delay the progression of cognitive impairment in patients with amnestic Mild Cognitive Impairment (MCI) as measured by cognitive testing, and brain magnetic resonance imaging (MRI) scans. Study participants will be assessed at baseline, six-month (cognitive tests only) and one-year follow-up.
This two-site randomized clinical trial will investigate and compare three treatments for insomnia in patients who have been diagnosed with and treated for sleep apnea: online cognitive behavioral therapy (OCBT), therapist-directed cognitive behavioral therapy (TCBT), and standard clinical care. 384 patients will be recruited and will attend up to 15 visits over 10 months. Visits will include baseline assessment, treatment visits, and post-treatment follow-up visits. Visits will involve completion of questionnaires, meeting with therapists, and a physical exam.
Telemonitoring for Positive Airway Pressure (PAP) therapy might help to establish and maintain long-term therapy adherence and thus support the beneficial effects of PAP therapy on long-term outcomes.
Rehabilitation results in a decrease of the perimeters of the limb with lymphedema by a decrease in the amount of liquid of the affected limb, with movement of the intracellular liquid towards the trunk and the neck then into the jugular-subclavian confluence, the superior vena cava and right atrium without modification of extracellular fluid. No study have evaluated the prevalence of sleep apnea syndrome in this population and the effect of this treatment on sleep apnea syndrome.
Obstructive sleep apnea (OSA) is a condition where the patient's breathing cease during sleep due to collapse of the oro-pharynx. The consequences are reduced quality of sleep, increased risk for developing cardiovascular disease and increased risk of accidents caused by daytime sleepiness. Among Norwegians 30-65 yrs, the prevalence of OSA are estimated to 16%. The golden standard in OSA-treatment is Continuous Positive Airway Pressure (CPAP). This is effective and must be used for life. However, CPAP-treatment might be uncomfortable for the patient, with poor compliance as a result. An alternative is Mandibular Advancing Splints (MAS), which is perceived as less troublesome and may initiate higher compliance. Through mapping of patient characteristics, the researchers investigate which patient-type benefits most from two different treatment-devices. The aim of the study is to assess how the MAS treatment differ from the CPAP treatment in respect to efficacy, compliance and impact on health related quality of life among patient diagnosed with mild/moderate OSA. All OSA patients referred to the Ear- Nose- Throat-department (ENT) at University Hospital, Northern-Norway (UNN) and St.Olavs Hospital were invited to participate in the study. The sample size at completion of the study should be 140 patients. Participants in the trial were randomly allocated to the two treatment groups, and assessed after 4 and 12 months of treatment. Data were collected through anamnesis, clinical examination, clinical photos, radiographs and questionnaires concerning general health related quality of life (SF36), oral health, cognitive aspects (HADS), sleep quality (PSQI), daytime sleepiness (Epworth's Sleepiness scale) and compliance.
Primary aim: The MOSAIC trial aims to assess the impact of a mandibular advancement device (MAD) on Apnea-Hypopnea Index (AHI) in Asian patients with Heart Failure with reduced Ejection Fraction (HFrEF) and obstructive sleep apnea (OSA). The investigators hypothesize that the AHI was 60% lower after 3-month treatment with MAD than with sham MAD. Secondary aims: The investigators also aim to determine i. the interaction between ethnicity (Chinese, Malay, Indians) and the effects of MAD in lowering AHI; ii. the effect of MAD on cardiac remodeling (LVEDVI assessed by cardiac magnetic resonance imaging [CMR]); iii. the characteristic craniofacial skeletal anatomy (using coned beam computed tomography [CT]) associated with OSA in Asian patients with HFrEF; iv. the association between self-reported adherence to MAD and cardiac remodeling; v. the effects of MAD on biomarkers of HF (N-terminal pro-B-type natriuretic peptide [NT-proBNP],high sensitivity cardiac troponin T [hs cTnT], high-sensitivity C-reactive protein [hs-CRP], and ST2); Rationale: OSA is associated with incident HF. The investigators will study Asian patients because a body of evidence suggests mechanisms for OSA differ between Asians and Caucasians. While obesity is the major contributing factor in Caucasians, craniofacial skeletal anatomy (short mandible, maxilla, and cranial base and a large mandibular volume) plays an important role in the development of OSA among Asians. Using cone beam CT, it has been shown that Asians have shorter mandibular, maxillary, and cranial base lengths and a greater mandibular volume compared with Caucasians. Using a MAD to adjust maxillary-mandibular juxta-positioning to maintain a patent airway may be an ethnic-specific approach to treat OSA in Asians.
This study seeks to understand the physical, physiologic and biologic features that predispose a woman to the development of obstructive sleep apnea once they are exposed to the cardiopulmonary and metabolic physiological changes of pregnancy. Knowing these specific predictive factors can help identify a population at risk and guide clinicians to develop suitable targeting screening strategies.
The main goal of this French multicenter observational cohort study is to prospectively collect data assessing the impact of the Adaptative Servo-Ventilation treatment on the quality of sleep of patients with central or combined sleep apnea syndrome (SAS) out of Heart Failure (HF) with altered ejection fraction, with a predominant central SAS.
