AIM: To assess the diagnostic accuracy of common carotid artery intima media thickness (CIMT) for coronary artery disease (CAD) detection in patients with obstructive sleep apnoea (OSA). MATERIALS & METHODS: Patients with clinically suspected OSA prospectively underwent polysomnography (PSG), ultrasound CIMT measurement and coronary computed tomography angiography (CTA). An average CIMT of ≥0.9 mm in either common carotid artery designated as a positive test...

In this paper, we present an approximation method for principal component analysis (PCA) and apply it to estimating the respiration from the overnight ECG signal. The approximation method is computationally fast with low memory requirements. We compare it to a full PCA method which is applied to segments of the ECG. Features were calculated from the two ECG derived respiration signals (EDR) and classifiers trained to detect obstructive sleep apnoea (OSA). The Extreme Learning Machine and Linear Discriminant classifier were used to classify the recordings...

We investigated using heart rate variability (HRV), ECG derived respiration and cardiopulmonary coupling features (CPC) calculated from night-time single lead ECG signals to classify one-minute epochs for the presence or absence of sleep apnoea. We used the 35 training recordings of the M.I.T. Physionet Apnea-ECG database. Performance was assessed with leave-one-record-out cross-validation. The best classification performance was achieved using the CPC features in conjunction with the time-domain based HRV parameters...

BACKGROUND AND OBJECTIVE: Mandibular movements (MMs) and position during sleep reflect respiratory efforts related to increases in upper airway resistance and micro-arousals. The study objective was to assess whether MM identifies sleep-disordered breathing (SDB) in patients with moderate to high pre-test probability. METHODS: This was a prospective study of 87 consecutive patients referred for an in-laboratory sleep test. Magnetometer-derived MM signals were incorporated into standard polysomnography (PSG)...

BACKGROUND AND OBJECTIVE: Clinical and epidemiological cohort studies have shown that obstructive sleep apnoea (OSA) is a common but largely undiagnosed disorder in senior subjects, where progressive deterioration of the pathology would be expected as a consequence of the ageing processes. Our study examines the longitudinal progression of OSA over a 7-year period in a community-based sample of healthy subjects. METHODS: The sample consisted of 284 volunteers, aged >65 years (52% women, 48% men) accepting clinical and instrumental follow-up at 7 years...

BACKGROUND: There are limited data on outcomes of hypoxaemic respiratory failure (HRF), especially in non-ICU settings. AIM: To assess outcomes in HRF (without multi-system disease and not requiring early intubation) directly admitted to a Respiratory High Dependency Unit (R-HDU). METHODS: Retrospective, cohort study of HRF compared to Hypercapnic Respiratory Failure (HCRF) in a R-HDU (2007-2011). Patient characteristics (age, gender, pre-morbid status, diagnoses) and outcomes (non-invasive ventilation (NIV) use, survival, ICU admission) were assessed...

BACKGROUND: Resistant hypertension is highly prevalent among the general hypertensive population and the clinical management of this condition remains problematic. Different approaches, including a more intensified antihypertensive therapy, lifestyle modifications, or both, have largely failed to improve patients' outcomes and to reduce cardiovascular and renal risk. As renal sympathetic hyperactivity is a major driver of resistant hypertension, renal sympathetic ablation (renal denervation) has been recently proposed as a possible therapeutic alternative to treat this condition...

BACKGROUND: Paediatric obstructive sleep apnoea syndrome (OSAS) is a highly prevalent condition carrying increased risk for impaired cognitive and cardiovascular function. The standard diagnosis consists of full-night polysomnography (PSG), but limited access to PSG leads to substantial under-diagnosis. The use of a validated and simple diagnostic screening tool to predict OSAS could prioritise night sleep recordings in children at risk of OSAS, and help in clinical decision-making. OBJECTIVE: This study aimed to prospectively assess the performance of the French version of the severity hierarchy score (SHS) in paediatric OSAS...

BACKGROUND: Catheter-based renal sympathetic denervation (RSD) significantly reduces blood pressure in patients with resistant hypertension, who commonly have obstructive sleep apnoea (OSA). These patients are considered particularly responsive to the antihypertensive effects of RSD, but additional benefits of metabolic control on sleep apnoea severity have not been thoroughly investigated. METHODS: The effect of RSD was evaluated prospectively in a cohort of patients with OSA (apnoea-hypopnea index (AHI) ≥15 events per hour and an Epworth Sleepiness Scale (ESS) score ≤9) and treatment resistant hypertension...

STUDY OBJECTIVES: To clinically validate the Flinders Fatigue Scale (FFS) as a brief measure of daytime fatigue, and to derive cut-off scores to classify fatigue severity. METHOD: The FFS was administered to 439 adult volunteers from the general population, 292 adults with insomnia, 132 adults with Obstructive Sleep Apnoea (OSA) and 66 adults with Chronic Fatigue Syndrome/Myalgic Encephalomyelitis (CFS/ME), together with the Fatigue Severity Scale (FSS) and the Epworth Sleepiness Scale (ESS)...

BACKGROUND: Sleep-disordered breathing (SDB) and Cheyne-Stokes respiration (CSR) are associated with shorter survival in patients with heart failure (HF). A novel treatment method for this patient group is unilateral phrenic nerve stimulation by the remedē® system, a transvenously implantable neurostimulation device, which has recently been studied in a large randomized, controlled trial. Previous literature has shown efficacy and safety of the treatment with this first-generation device, but hardly any data is available on long-term clinical parameters, the remedē® device's battery lifetime, device exchangeability, lead position stability, surgical accessibility and manageability...

STUDY OBJECTIVES: The aim of this study is to investigate changes in regional cerebral blood flow (rCBF) in awake people with untreated severe obstructive sleep apnoea (OSAs) compared with good sleepers (GSs). DESIGN: Arterial spin labelling perfusion imaging was used to quantify cerebral perfusion based on resting-state functional magnetic resonance imaging (MRI). SETTING: Lying supine in a 3.0-T magnetic resonance imaging scanner in the night was done...

Jia Li, Qianwen Ming, Weihong Lin
Sudden unexpected death in epilepsy (SUDEP) is a major cause of death in patients with refractory epilepsy, particularly those with chronic epilepsy. The physiopathological mechanisms underlying SUDEP have not been elucidated. Autonomic dysregulation of cardiac or respiratory function is thought to underlie SUDEP. Here, we present a summary of available evidence on the involvement of the insular lobe in the regulation of cardiorespiratory function. Ictal discharge that originates in the cortex can, primarily or secondarily, involve the insula lobe through epileptogenic signal networks, leading to cardiorespiratory dysfunction, central apnoea, arrhythmias, and sudden death in patients with epilepsy...

OBJECTIVES: Intracapsular tonsillectomy (tonsillotomy) has been used internationally, mainly in the management of obstructive sleep apnoea, rather than recurrent tonsillitis, with little published data evaluating its use for this latter indication. We present long-term prospective data from 500 paediatric cases undergoing Coblation(®) intracapsular tonsillectomy, for both obstructive and infective indications. DESIGN: Prospective case series, March 2013-January 2016, all with completed follow up...

BACKGROUND: Among authors studying morphological determinants of the Obstructive Sleep Apnoea (OSA) controversies exist on the location of the narrowest area within the pharynx critical for development of obstruction. Those disagreements primarily revolve around differences between obese and nonobese OSA patients. Determination whether the location and size of the narrowest area within the pharynx differentiates the obese and nonobese OSA patients. MATERIALS AND METHODS: A population of 55 subjects was investigated after being diagnosed with OSA in the Polysomnography Laboratory of the Department and Clinic of Otolaryngology in the Medical University of Warsaw...
