Relationship Between Normal-weight Central Obesity and Obstructive Sleep Apnea

Sleep DisorderBody Fat Distribution

Comparison of the prevalence of obstructive sleep apnea (OSA), measured by polysomnography in normal weight patients with central obesity by body mass index (BMI) and waist hip ratio (WHR), with normal weight patients without central obesity by BMI and WHR. Evaluation of arterial stiffness and vascular age in normal weight patients with central obesity and in normal weight patients without central obesity. Determination of the exercise response characteristics in OSA patients.

Inflammation and Neurocognitive Damage Markers in Elderly People With Obstructive Sleep Apnea

Obstructive Sleep ApneaSleep Apnea7 more

The aging process tends to promote an overall increase in inflammation compromising the immunologic system regulation, sleep/wakefulness pattern, and neurocognitive performance. In elders, there is an increase in repetitive arousals during sleep, secondary to breathing interruption by pharynx collapse, generating a transient reduction in oxygen delivery to the brain known as obstructive sleep apnea. This lack in oxygen supply results in an inflammatory process producing brain damage. Some substances present in the blood seem to be associated to neurocognitive damage, like S100β protein, cortisol, interleukin 1-β,6 and TNF-α. In the other way, a substance called brain-derived neurotrophic factor (BDNF) enhances cognitive function, and memory consolidation improvement.

High-resolution Oximetry to Diagnose Obstructive Sleep Apnea

Sleep Apnea

The aim of this study was to compare an overnight digital monitoring device (ODM) with home sleep apnea testing (HSAT) using respiratory flow and effort parameters in a large population sample, who were in a waiting list for Polysomnography (PSG).

Management of Sleep Apnoea Syndrome (SAS) in Patients With Vasovagal Syncope (VVS)

SyncopeVasovagal1 more

This is a multi-centre, registry-based study whose primary objective is to evaluate the effect of treatment for sleep apnoea syndrome (SAS) on the number of syncope/malaise episodes in a population suffering from both idiopathic, recurrent vasovagal syncope/malaises and SAS.

Home Respiratory Polygraphy in Childhood Sleep Apnea-Hypopnea Syndrome (CHILDSLEEP).

Sleep ApneaHome Respiratory Polygraphy Sleep Study3 more

The aims of the study is to assess the diagnostic utility of home respiratory polygraphy (HRP) complemented with polysomnography (PSG) in childhood Obstructive Sleep Apnea-Hypopnea Syndrome (OSAS), as well as its usefulness in the therapeutic decisions. Methods: Children referred with suspected OSAS will be evaluated during one year performing home respiratory polygraphy in all cases. PSG will be chosen in patients with concomitant pathology or according to medical criteria, or complemented with HRP in doubtful cases. Clinical and anthropometric data, severity, technical quality and treatment will be obtained. Patients will be divided in two groups (HRP vs PSG) and compared, and the accuracy from HRP to establish a therapeutic decision it wil calculated. The investigator's hypothesis is that PSG should be recommended only for complex or doubtful cases.

Continuous Positive Airway Pressure (CPAP) Compliance in Obstructive Sleep Apnea

Sleep ApneaObstructive1 more

This study aims to determine the average compliance of a patient under CPAP therapy for obstructive sleep apnea as well as the various factors that influence it.

CPAP Effect on Blood Pressure and Arterial Stiffness in Obstructive Sleep Apnea Patients With Resistant...

HypertensionResistant to Conventional Therapy1 more

Resistant hypertension is defined as uncontrolled blood pressure (BP ≥ 140/90mmHg) despite the current use of three or more antihypertensive drugs at full doses, including a diuretic. Obstructive Sleep Apnea (OSA) is at high risk for cardiovascular morbidity and is highly prevalent in patients with resistant hypertension. The prospective observational POP-ART study will assess the efficacy of continuous positive airway pressure (CPAP) treatment on BP in patients with resistant hypertension and collect data from usual care.

Inflammatory Markers in Infants With Obstructive Sleep Apnea

Obstructive Sleep Apnea Syndrome

Obstructive sleep apnea syndrome (OSAS) is a common disorder in children (2-3%). OSAS in turn, is associated with significant behavioral, learning, and heart problems. Adenotonsillectomy (T&A, meaning the removal of tonsils and adenoids) is the most common treatment for the problem .Diagnosis of OSAS in children is based on overnight polysomnography (sleep study). Recent studies suggest that upper airway and systemic inflammatory changes exists in school-age children and adults with OSAS, and that anti inflammatory therapy can improve respiratory parameters during sleep and reduce adenoid size, similar to surgery. However, there are no data in the literature on inflammatory changes in infants with the disorder. Healthcare resources utilization, a sensitive marker for diseases is consumed by young children (<3y) with OSAS more then healthy children, from their first year of life We hypothesize that infants and young children with OSAS present local inflammatory changes of the airways as well as systemic inflammation (in the blood or urine) that contribute to the learning, growing and heart associated medical problems. The Aims of the present study are to characterize the local and systemic inflammatory changes of young children with OSAS, and to evaluate their associated medical problems at diagnosis and after therapy (T&A) If indeed inflammation is "responsible" for the development of OSAS at such a young age it should be reduced following therapy (i.e. T&A). In such a case bio-markers may become a part of the algorithms for diagnosis and follow up of such patients.
