Filter by:The aim of our study was to assess the levels of inflammatory biomarkers in a large sample of OSA patients and to investigate any correlation between these markers with clinical and polysomnographic (PSG) parameters. Subjects undergone a PSG for OSA diagnosis were recruited. Patients with known comorbidities were excluded from the study. Included patients were grouped according to apnea-hypopnea index (AHI) as mild, moderate and severe. Patients with AHI < 5 served as control group. Demographic, PSG data, serum levels of hs-C-reactive protein (hs-CRP), fibrinogen, erythrocyte sedimentation rate (ESR) and Uric Acid (UA) were measured and compared between groups.
Study of tongue implant for treatment of obstructive sleep apnea
This study is to evaluate a commercial tool on the market (Fitbit®) that also quantifies sleep. No one has studied how pediatric patients perform with it and how accurate it is in measuring their quality of sleep. This study will use the obstructive sleep apnea (OSA) questionnaire completed by parents and Fitbit® together and evaluate how they perform against the polysomnography (PSG).
It is widely accepted that coronary artery disease (CAD) is related to a high mortality. It is predicted that an increase of approximately 21.3 million cardiovascular events and 7.7 million cardiovascular deaths over 2010 to 2030 in China.1 Male sex, diabetes mellitus, hypertension, hypercholesterolemia, obesity and smoking are all traditionally considered as risk factors for CAD. In recent decades, tremendous progress toward the prevention and treatment of traditional cardiovascular risk factors have helped decrease the morbidity and mortality from CAD, but the condition remains a major public health challenge worldwide. Looking into the other potential risk factors (OSA) for CAD, it may help to develop additional preventative strategies and further reduce the incidence and mortality of CAD.
Women with PCOS and OSA, compared to women with PCOS only, have more severe clinical and biochemical features of PCOS and impaired QoL. This is an observational cross-sectional study in a secondary care PCOS clinic in the WISDEM Centre, University Hospital Coventry. The primary aim of this study is to examine the relationship between OSA and impaired QoL in women with PCOS. Study secondary outcomes are to examine the relationship between OSA and the clinical and biochemical features in women with PCOS.
The purpose of this study is to help us understand how HIV and/or Anti-Retroviral Therapy (ART) may predispose individuals to Obstructive Sleep Apnea (OSA). The traditional risk factors for OSA are weight and age. However, people living with HIV on ART seem to have OSA even when they are thin and young. The study involves a detailed physiological sleep study and an MRI of the head and neck to understand the underlying cause of OSA in those with and without HIV.
Obstructive sleep apnea (OSA) is a prevalent disease, and one that is associated with significant negative impact on long-term survival. There is convincing evidence that treatment of OSA can improve outcome in patients with cardiovascular disease, improve blood pressure and blood glucose control, and improve the overall metabolic syndrome. Treatment is usually with continuous positive airway pressure (CPAP). However, many patients face problems with their CPAP interfaces, affecting their compliance and response to treatment. Proper mask fit is important in decreasing air leak and increasing comfort, thus leading to better compliance. Currently, the choice of interfaces depends mainly on the experience of the sleep disorder unit (SDU) technicians. Unsuitable choice of interface not only affects response to treatment but also increases medical costs when interfaces need to be replaced to better fitting ones. It is thus important to develop selection criteria to objectively guide the SDU technicians in choosing the suitable interfaces. The objective of this study is to study the facial profile of patients and look for predictive indices that can be used to objectively guide the choice of appropriate interfaces. Frontal and side profile photographs of patients will be taken and facial measurements will be recorded. Patients will then be given a one monthly trial of each of the 3 interfaces (nasal masks, oronasal masks, nasal cushions) in a randomised order. The patients' subjective perception of each of the interface will be assessed and patients will nominate their preferred interface at the end of the trial. The amount of leak and the hours of adherence for each type of interface will also be analysed. A multinomial logistic regression analysis will then be done to look for facial measurements that will predict the interface that patients will be most satisfied with. Hypothesis That measurement of facial structures and clinical features will be able to predict the best-fit CPAP interface for each patient. Study Objective - To determine anthropometric facial measurements and clinical factors important in achieving a good interface fit for each patient - To derive a prediction rule or equation that will be able to accurately predict which interface a patient should be prescribed
This study is a prospective, multi-center, randomized crossover of the NightBalance SPT compared to APAP for the treatment of Positional Obstructive Sleep Apnea (POSA).
Those patient's that come to the sleep unit and that accept to participate in the study will undergo a polysomnography with the extra of an actigraphy placed in their no dominant arm wrist. The outcomes that will be analyzed are: Time in bed, assumed sleep time, wake time, sleep efficiency, sleep latency, light's on/light's off
The study aimed to examine the effect of Continuous Positive Airway Pressure (CPAP) initiation for newly diagnosed obstructive sleep apnea (OSA) in hospitalized heart failure patients on reducing 30-day hospital readmission rate through a clinical trial.
