OBJECTIVE To assess the effects of didgeridoo playing on daytime sleepiness and other outcomes related to sleep by reducing collapsibility of the upper airways in patients with moderate obstructive sleep apnoea syndrome and snoring. DESIGN Randomised controlled trial. SETTING Private practice of a didgeridoo instructor and a single centre for sleep medicine. PARTICIPANTS 25 patients aged ...

Upper airway compliance indicates the potential of the airway to collapse and is relevant to the pathogenesis of obstructive sleep apnea. We hypothesized that compliance would vary over the rostral-to-caudal extent of the pharyngeal airway. In a paralyzed isolated upper airway preparation in cats, we controlled static upper airway pressure during magnetic resonance imaging (MRI, 0.391-mm resolu...

Objective: One of the most common side effects spinal anesthesia (SA) is hypotension. The aim study was to evaluate efficacay inferior vena cava (IVC) diameter measurements, perfusion index (PI) and pleth variability (PVI) values in determining risk developing hypotension after SA. Materials Methods: This conducted on 81 patients who underwent transurethral prostatectomy. Before administration ...

When a study outcome is rare in all strata used for an analysis, the odds ratio estimate of causal effects will approximate the risk ratio; therefore, odds ratios from most case-control studies can be interpreted as risk ratios. However, if a study outcome is common, the odds ratio will be further from 1 than the risk ratio. There is debate regarding the merits of risk ratios compared with odds...

association has been described with similar results and could be due to a combination of the effects of obesity and diffuse airway obstruction. Obesity is known to be a major risk factor for OSA linked with increased neck circumference and amounts of peripharyngeal fat, which could narrow and compress the upper airway; obesity may also play a role by reducing lung volumes. Obesity affects ERV b...

The constraint satisfaction probem (CSP) is a well-acknowledged framework in which many combinatorial search problems can be naturally formulated. The CSP may be viewed as the problem of deciding the truth of a logical sentence consisting of a conjunction of constraints, in front of which all variables are existentially quantified. The quantified constraint satisfaction problem (QCSP) is the ge...

Introduction: Measures of carotid artery flow or inferior vena cava diameter were recently shown to predict fluid responsiveness. Both are relatively superficial large vessels which can provide straightforward ultrasound evaluation & high-qualityimages.Methods: Our study is a prospective observational on 30 mechanically ventilated septic shock patients in ICUto assess the responsivenessby m...
