Opis:
Sleep-related disordered breathing (SRDB) is a term covering a heterogeneous group of conditions with a similar clinical picture yet different pathogenesis. Nocturnal episodes of obstructive apnoea, leading to repeated periods of desaturation and re-oxygenation, activate chemoreceptors and increase the activity of the sympathetic as well as renin-angiotensin-aldosterone system. Moreover, the generation of free radicals and proinflammatory cytokines increases. All the above mentioned disturbances interfere with the function of endocrine glands. On the other hand, many endocrine disorders are associated with an increased risk of obstructive sleep apnoea syndrome (OSAS). In this paper, we discuss relationships between selected endocrinopathies and OSAS.

Opis:
Obstructive sleep apnea (OSA) is a long-term sleep disorder that causes temporary disruption in breathing while sleeping. Polysomnography (PSG) is the technique for monitoring different signals during the patient’s sleep cycle, including electroencephalogram (EEG), electromyography (EMG), electrocardiogram (ECG), and oxygen saturation (SpO2). Due to the high cost and inconvenience of polysomnography, the usefulness of ECG signals in detecting OSA is explored in this work, which proposes a two-dimensional convolutional neural network (2D-CNN) model for detecting OSA using ECG signals. A publicly available apnea ECG database from PhysioNet is used for experimentation. Further, a constant Q-transform (CQT) is applied for segmentation, filtering, and conversion of ECG beats into images. The proposed CNN model demonstrates an average accuracy, sensitivity and specificity of 91.34%, 90.68% and 90.70%, respectively. The findings obtained using the proposed approach are comparable to those of many other existing methods for automatic detection of OSA.

Opis:
Introduction: Snoring and obstructive sleep apnea (OSA) are associate with a high socio-economic burden. According to statistics snoring is found in 44% of men and 28% of women aged 30 to 60 years. Treatment involves several main approaches including uvulopalatopharyngoplasty with or without tonsillectomy. Preparation for this procedure includes sleep videoendoscopy. Currently, we mainly use two effective agents, propofol and dexmedetomidine. That said, there is still no consensus on which one is safer and better. Material and methods: The study involved 50 people aged 18 to 62 with a history of snoring and OSA, previously ineligible or insensitive to CPAP therapy, thus preparing for surgical treatment of these disorders. All patients were randomized to two study groups: group 1 with propofol as a sedative and group 2 with dexmedetomidine. Each treatment was divided into three periods: (1) initial testing before the use of intravenous hypnotic agents, (2) sedation, and (3) regaining consciousness. In each period, we measured the following parameters: minute ventilation, respiratory rate, oxygen saturation, blood concentration of hypnotic agent, BIS index. Statistical analysis was performed on IBM SPSS Statistics v. 22. Results: The OAA/S scale showed that the recovery time after sedation was longer for dexmedetomidine than for propofol: 38 ± 10 min and 27 ± 3 min, respectively (p value = 0.305, which means no statistically significant difference between the groups). Based on monitoring of circulation and respiratory rate, heart rate tended to decrease with dexmedetomidine seda tion and increase with propofol infusion. Blood pressure tended to drop in both groups, more so with dexmedetomidine. In the post-sedation period, blood pressure stabilized faster in the propofol group than in the dexmedetomidine group, but it was not statistically significant. Conclusion: According to the study results, there was no statistically significant difference between the propofol or dexmedetomidine groups. However, the paper presents a small series of cases, therefore extensive clinical research is needed to clarify the problem further.

Introduction. The epidemic of obesity has led to an increase in the occurrence of obstructive sleep apnea and gastro-esophageal reflux disease. The mechanism of development of gastro-esophageal reflux disease is multifactorial, and studies conducted in the last decade have shed new light on the causes of its development in patients with sleep apnea and obesity. Aim. The aim of the study was to discuss the mechanism of development of gastro-esophageal reflux disease is multifactorial, and studies conducted in the last decade have shed new light on the causes of its development in patients with sleep apnea and obesity and the dysfunction of the lower esophageal sphincter. Material and methods. An analysis of literature regarding gastro-esophageal reflux and obstructive sleep apnea. Results. In obstructive sleep apnea and obesity, high levels of cytokines and insulin resistance are observed, resulting in disorders in the levels of ghrelin – a hormone responsible for normal gastrointestinal motility. Conclusion. The effect of deviations in the ghrelin profile on the development of gastro-esophageal reflux disease remains a matter for further research

Opis:
Obstructive sleep apnea usually requires all-night examination in a specialized clinic, under the supervision of a medical staff. Because of those requirements it is an expensive and a non-widely utilized test. Moving the examination procedure to patients’ home with automatic analysis algorithms involved will decrease the costs and make it available for larger group of patients. The developed device allows all-night recordings of the following biosignals: three channels ECG, thoracic impedance (respiration), snoring sounds and larynx vibrations. Additional information, like patient’s body position changes and electrodes’ attachment quality are estimated as well. The reproducible and high quality signals are obtained using the developed and unobtrusive device.

This paper proposes a comprehensive study on machine listening for localisation of snore sound excitation. Here we investigate the effects of varied frame sizes, and overlap of the analysed audio chunk for extracting low-level descriptors. In addition, we explore the performance of each kind of feature when it is fed into varied classifier models, including support vector machines, k-nearest neighbours, linear discriminant analysis, random forests, extreme learning machines, kernel-based extreme learning machines, multilayer perceptrons, and deep neural networks. Experimental results demonstrate that, wavelet packet transform energy can outperform most other features. A deep neural network trained with subband Energy ratios reaches the highest performance achieving an unweighted average recall of 72.8% from four types for snoring.

Objectives The main aim has been to examine psychometric properties of STOP-Bang (snoring, tiredness, observed apnea, high blood pressure, body mass index (BMI), age, neck circumference, male gender) scoring model (Serbian translation), an obstructive sleep apnea (OSA) screening tool, in a sample of commercial drivers. Material and Methods After formal translation, validation was performed on a sample of bus and truck drivers evaluating test-retest reliability, construct and criterion validity. Overnight polysomnography or cardiorespiratory polygraphy were used for OSA diagnosis purposes. Results One hundred male participants, 24–62 years old, were included. STOP-Bang classified 69% as potential OSA patients. Polysomnography identified OSA in 57% of the sample. Test-retest reliability (Cohen’s κ = 0.89) was adequate. STOP-Bang score was significantly correlated to apnea-hypopnea index (AHI) and OSA severity. Sensitivity was 100% for AHI ≥ 15, highest specificity was 53.5% (AHI ≥ 5). Conclusions STOP-Bang showed good measurement properties, supporting its further use in OSA screening of commercial drivers. Int J Occup Med Environ Health 2016;30(5):751–761

Opis:
Obstructive sleep apnea (OSA) is characterized by recurrent periods of upper airway obstruction (hypopneas and apneas) during sleep. It leads to repeated oxyhemoglobin desaturations, nocturnal hypercapnia, and arousals. Common symptoms include loud snoring with breathing interruptions. Excessive daytime sleepiness and cognitive impairment occur. Obstructive sleep apnea is a major cause of morbidity and mortality in Western society. Its association with an increased risk of development and progression of neurocognitive, metabolic, cardiovascular and oncologic diseases and complications is well described. The significant factor in OSA pathogenesis is reduced muscle tone in the tongue and upper airway. In the recent years, devices providing neurostimulation of the hypoglossal nerve (HGNS) were developed as an alternative for noncompliant CPAP (continuous positive airway pressure) patients. Clinical trials suggest that electrical stimulation of the hypoglossal nerve is effective. This is considered to be one of the targets of neurostimulation in the treatment of obstructive sleep apnea (OSA).

Purpose: The purpose of this study was to determine the presence of dry eye disease and possible treatment options in patients with obstructive sleep apnea and continuous positive airway pressure. Materials and methods: A total of 72 patients (midlife age) with obstructive sleep apnea and continuous positive airway pressure therapy underwent a comprehensive eye examination. Fluorescein staining of the anterior ocular surface and tear break-up test were performed. All of the patients who were diagnosed with dry eye disease received personalized therapy. One month later, re-examination was performed using the same methodology and clinical settings. Results: On the first examination, 48 of 72 patients (66.67%) were diagnosed with dry eye disease. Floppy eyelid syndrome was reported in 26 patients (54.17%) with dry eye disease. The treatment of 40 patients included artificial tear supplements during the day in combination with high-viscosity topical gels before bedtime. In more severe cases (10.42% of all participants), the application of bandage contact lenses for 3 months was necessary. Because of excessive lid laxity, surgical reconstruction of the eyelids was performed in three patients (6.25%). Conclusions: A multidisciplinary approach is essential for obstructive sleep apnea. Practitioners from different specialties must be well acquainted with risk factors, signs, and symptoms. The early detection of dry eye disease in patients with obstructive sleep apnea and appropriate treatments are important for improving the quality of life in this patient group.

Opis:
Obstructive sleep disordered breathing (SDB) is a common clinical problem. An unrecognized and untreated SDB is a serious threat for an intensively developing organism of a child. The consequences of SDB include cardiovascular and neurological complications, growth disorders and enuresis. Therefore, SDB in children becomes an important subject of many scientific investigations, publications and congresses. In 2015 the European Respiratory Society Task Force published a document concerning the conclusions about the diagnostics and treatment of SDB in children and youth from 2 to 18 years of age (Fig. 1). The scientific data from 362 publications were presented in a condensed form of “seven steps”, very useful in diagnosing and treatment planning (1). The authors underline the limited number of the reliable evidence about SDB: prospective studies, randomized double-blinded studies with placebo. The presented evidence was categorized depending on their quality according to the classification of the American Academy of Neurology (ANN) into classes I – IV. Previously, in 2012, the guidelines of the American Academy of Pediatrics on obstructive sleep apnea syndrome (OSAS) in children with tonsillar hypertrophy and/or obesity were published (2, 3) and they were a valuable diagnostic and therapeutic compendium. The European guidelines discussed in this article result from the progress of knowledge in the recent years, they cover the subject broadly, consider rare and difficult cases and present the spectrum of potential therapeutic actions. The aim of the guidelines is a better recognition of SDB, a systematization of diagnosis and treatment at every stage of medical care, including the causes of this disorder and its complications.

Opis:
This paper presents the study of algorithms for derivation of respiration waveform from the electrocardiogram. The problem has considerable clinical impact, because the heart rate and respiration are both driven by the central nervous system, and commonly used low-cost Holter recording may be used for efficient detection of breath disturbances (e.g. apnea). Three methods based on: heart rate, heart position and lung resistance influencing the ECG amplitude were compared in our research. Among 18 volunteers breathing at a controlled frequency all implemented algorithms show acceptable sensitivity of order of 97% in slow breathing phases detection. In fast breathing the sensitivity is reduced to 90%, since the heart beats are too sparse with regard of respiration waveform.

Opis:
Obstructive sleep apnea (OSA) is a common problem. Excessive daytime sleepiness raises a suspicion of OSA, which can be confirmed by polysomnography (PSG). Insomnia, in patients with OSA, often manifests itself as excessive daytime drowsiness. The incidence of insomnia among patients with OSA differs in different studies. Thus, we investigated the incidence of insomnia among our patients. We included 120 patients who underwent a workup due to a suspicion of OSA in the Polysomnography Laboratory, Department of Otolaryngology, Medical University of Warsaw, Poland. Patients completed the Athens Insomnia Scale (AIS). All-night PSG was done with 14-channel recordings (Grass®, USA). The severity of OSA was classified according to the apnea-hypopnea index (AHI) values. There were 96 patients with OSA and 24 patients without OSA who served as controls (their sleep disorders and daytime drowsiness were not caused by OSA). The total AIS scores tended to indicate insomnia in the entire sample and in all different subgroups. The mean AIS score was significantly different between the subgroups differing in the severity of apnea. The mean AIS score correlated significantly with sleep latency, latent sleep, and N2 latency. The mean AIS score did not correlate significantly with the AHI. In conclusion, in patients with OSA, insomnia, measured with the AIS, was associated with the severity of apnea, although this relationship was weak.
