Filter by:The objective of this study is to simultaneously acquire sleep and breathing data using the under-mattress Sleeptracker (The Sleeptracker-AI Monitor (Fullpower Technologies, California, USA) during routine PSGs in patients who attend the Woolcock Institute for undergoing investigation for possible obstructive sleep apnoea (OSA).
To evaluate the clinical predictors of OSA in patients with ILD
Current therapies available for obstructive sleep apnea (OSA) have varying degrees of efficacy due to the complex nature of the disorder. A reduction in pharyngeal muscle activity characterizes OSA, and recent research has shown that combining atomoxetine and oxybutynin improves OSA severity. Thus this may be a viable treatment option. However, the specific effects of these agents alone and in combination on pharyngeal muscle activity remain unknown. The current study will look at the impact of each drug on pharyngeal muscles to gain insight into the mechanisms of this combination.
This prospective observational study will enroll 60 moderate-to-severe OSA patients (AHIā§15/hour, 30 obese [BMI>=27] & 30 non-obese [BMI<27]) and 40 age-, gender-, BMI-matched controls without OSA. Venous blood 10 ml will be collected to isolate neutrophils, which are later tested for their ability to produce neutrophil extracellular traps (NETs) under the effect of PMA (phorbol 12-myristate 13-acetate). The test will be repeated if OSA patients receive CPAP therapy (continous positive airway pressure therapy).
The goal of the study is to test the role of telemedicine combined with humidification to check CPAP treatment during the first month to improve adherence and reduce unsolved side effects of therapy.
The presence of protein in urine is a common laboratory finding in children. Although proteinuria is usually benign, it can be a marker of a serious underlying renal disease or systemic disorder. Microalbuminuria can be one of the first subclinical manifestations of endothelial dysfunction and is associated with low grade systemic inflammation. Multiple studies from the adult population suggest that microalbuminuria above the upper quartile is linked with increased risk of coronary heart disease and death even after adjustment for the presence of diabetes mellitus, obesity and hypertension. Obstructive sleep apnea (OSA) has been recognized as an independent risk factor for cardiovascular morbidity related to sympathetic nervous system overflow, metabolic dysregulation, inflammation and endothelial dysfunction secondary to repetitive hypoxia -reoxygenation events. Therefore, there is a need for further studies to investigate the association between OSA and microalbuminuria in children. Furthermore, no studies have thus far investigated the association between other sleep disorders such as periodic limb movement (PLMD) and microalbuminuria in children. Our hypothesis is that children with sleep disorders or short sleep duration have increased risk of proteinuria/microalbuminuria and that treatment and resolution of the sleep problem will be followed by improvement in proteinuria levels.
It is a randomized, double-blind, single-center, 30-day study. Patients aged 35-60 years, with apnea and hypopnea index and respiratory disturbance index normalized with CPAP, and Epworth Sleepiness Scale> 11. Patients undergo baseline and CPAP titration polysomnography, liquor and blood collection, Multiple Sleep Latency Test, anxiety and depression and cognitive assessments.
Drug induced sleep endoscopy (DISE) is an increasingly performed procedure, offering dynamic upper airway evaluation during artificial sleep before surgical treatment for patients with obstructed sleep apnea (OSA). DISE is a safe procedure, easily practicable, valid and reliable. The investigators consider it a fundamental clinical procedure that is essential before choosing the surgical treatment. The investigator's results so far suggest that a multilevel collapse is significantly associated with higher apnea hypopnea index values. The investigators think that the weight did not play a significant role in RDI reduction. Results till now show that tailored surgery based on DISE may leverage sleep surgeries outcome significantly, presenting 70% success rate based on the investigator's experience The aim of this study is to evaluate surgery results in patients who underwent DISE prior to their surgery in comparison to their condition prior to the treatment.
