Interrelationships between oxidative stress and MMP-9 in subjects with severe obstructive sleep apnea syndrome
2016
Obstructive sleep apnea syndrome (OSAS) is significantly and independently associated with an increased risk of cardiovascular diseases, cerebrovascular events and all-cause mortality and some studies have demonstrated that the incidence of cardiovascular events is related to its severity. Our aim was to examine the oxidative status and the matrix metalloproteases (MMP) profile in a group of subjects with OSAS. We enrolled 48 subjects with OSAS, defined after a 1-night cardiorespiratory sleep study, which were subsequently subdivided in two subgroups according to the severity of OSAS: mild-moderate OSAS = “Low”, severe OSAS = “High”. We measured the parameters of oxidative stress, such as l…
Resumption of Ventilation at the End of Obstructive Sleep Apneas is not Determined by Diaphragmatic Fatigue
1988
In patients affected by obstructive sleep apnea syndrome (OSAS) a progressive increase of the force developed by the respiratory muscles is usually observed during the occlusive phase before upper airway patency is resumed (Onal and Lopata, 1986).

Positive airway pressure level based upper airway collapsibility classification - the European Sleep Apnea Database (ESADA)
2021
Background and objectives: Obstructive sleep apnea (OSA) patients with mild upper airway collapsibility represents a target group for potential non-positive airway pressure (PAP) treatment. We studied the clinical characteristics of this endotypic group in a large Pan-European sleep apnea registry. Methods: A retrospective analysis was performed in 2541 OSA patients with fixed PAP treatment (male 74%, age 53±11 years, body mass index [BMI] 33±6 kg/m2, apnea-hypopnea index [AHI] 41±25 events/h at baseline). Therapeutic PAP level ≤8 cm H2O was used as the cut-off to classify patients with mild upper airway collapsibility (Landry SA et al. Sleep 2017; 40:6). Results: Mean pressure of the PAP t…

Obesity and Obstructive Sleep Apnea
2021
Obstructive sleep apnea (OSA) is characterized by upper airway collapse during sleep. Chronic intermittent hypoxia, sleep fragmentation, and inflammatory activation are the main pathophysiological mechanisms of OSA. OSA is highly prevalent in obese patients and may contribute to cardiometabolic risk by exerting detrimental effects on adipose tissue metabolism and potentiating the adipose tissue dysfunction typically found in obesity. This chapter will provide an update on: (a) the epidemiological studies linking obesity and OSA; (b) the studies exploring the effects of intermittent hypoxia and sleep fragmentation on the adipose tissue; (c) the effects of OSA treatment with continuous positi…
Blood pressure reduction following treatment with positive airway pressure in sleep apnea: data from the European Sleep Apnea Database
2020
Abstract Introduction Positive airway pressure (PAP) treatment modifies blood pressure (BP) in patients with obstructive sleep apnea (OSA). We aimed to explore which factors that influence the BP response to PAP therapy in the European Sleep Apnea Database (ESADA). Methods A total of 2662 OSA patients with PAP therapy ≥90 days were included in the analysis (74% male, age 55±11 years, body mass index 32.3±6.1 kg/m2, 47% hypertensives, apnea-hypopnea index 40±24 events/h, treatment duration 1.0±1.1 years, PAP compliance 5.2±1.9 h/day). Anthropometric data, co-medications and office BP were assessed at baseline and follow-up visit. Results Systolic and diastolic BP were modestly reduced after …
Self-reported sleep duration and cognitive functioning in the general population
2009
This study investigated the relationship between self-reported sleep factors (sleep duration, insomnia, use of sleeping medicine, probable sleep apnoea and feelings of fatigue and tiredness) with cognitive functioning in 5177 people aged 30 years or older from a cross-sectional representative sample of the adult population in Finland (The Finnish Health 2000 Survey). Previous studies have indicated a U-shaped association between increased health risks and sleep duration; we hypothesized a U-shaped association between sleep duration and cognitive functioning. Objective cognitive functioning was assessed with tasks derived from the Consortium to Establish a Registry for Alzheimer's Disease te…
