Texto completoThis thesis describes the work carried out during four treks, each over 10-11 days, from 1400m to 5000m in the Nepal Himalaya and further work performed during several two-night sojourns at the Barcroft Laboratory at 3800m on White Mountain in California, USA. Nineteen volunteers were studied during the treks in Nepal and seven volunteers were studied at White Mountain. All subjects were normal, healthy individuals who had not travelled to altitudes higher than 1000m in the previous twelve months. The aims of this research were to examine the effects on sleep, and the ventilatory patterns during sleep, of incremental increases in altitude by employing portable polysomnography to measure and record physiological signals. A further aim of this research was to examine the relationship between the ventilatory responses to hypoxia and hypercapnia, measured at sea level, and the development of periodic breathing during sleep at high altitude. In the final part of this thesis the possibility of preventing and treating Acute Mountain Sickness with non-invasive positive pressure ventilation while sleeping at high altitude was tested. Chapter 1 describes the background information on sleep, and breathing during sleep, at high altitudes. Most of these studies were performed in hypobaric chambers to simulate various high altitudes. One study measured sleep at high altitude after trekking, but there are no studies which systematically measure sleep and breathing throughout the whole trek. Breathing during sleep at high altitude and the physiological elements of the control of breathing (under normal/sea level conditions and under the hypobaric, hypoxic conditions present at high altitude) are described in this Chapter. The occurrence of Acute Mountain Sickness (AMS) in subjects who travel form near sea level to altitudes above 3000m is common but its pathophysiology not well understood. The background research into AMS and its treatment and prevention are also covered in Chapter 1. Chapter 2 describes the equipment and methods used in this research, including the polysomnographic equipment used to record sleep and breathing at sea level and the high altitude locations, the portable blood gas analyser used in Nepal and the equipment and methodology used to measure each individual’s ventilatory response to hypoxia and hypercapnia at sea level before ascent to the high altitude locations. Chapter 3 reports the findings on the changes to sleep at high altitude, with particular focus on changes in the amounts of total sleep, the duration of each sleep stage and its percentage of total sleep, and the number and causes of arousals from sleep that occurred during sleep at increasing altitudes. The lightest stage of sleep, Stage 1 non-rapid eye movement (NREM) sleep, was increased, as expected with increases in altitude, while the deeper stages of sleep (Stages 3 and 4 NREM sleep, also called slow wave sleep), were decreased. The increase in Stage 1 NREM in this research is in agreement with all previous findings. However, slow wave sleep, although decreased, was present in most of our subjects at all altitudes in Nepal; this finding is in contrast to most previous work, which has found a very marked reduction, even absence, of slow wave sleep at high altitude. Surprisingly, unlike experimental animal studies of chronic hypoxia, REM sleep was well maintained at all altitudes. Stage 2 NREM and REM sleep, total sleep time, sleep efficiency and spontaneous arousals were maintained at near sea level values. The total arousal index was increased with increasing altitude and this was due to the increasing severity of periodic breathing as altitude increased. An interesting finding of this research was that fewer than half the periodic breathing apneas and hypopneas resulted in arousal from sleep. There was a minor degree of upper airway obstruction in some subjects at sea level but this was almost resolved by 3500m. Chapter 4 reports the findings on the effects on breathing during sleep of the progressive increase of altitude, in particular the occurrence of periodic breathing. This Chapter also reports the results of changes to arterial blood gases as subjects ascended to higher altitudes. As expected, arterial blood gases were markedly altered at even the lowest altitude in Nepal (1400m) and this change became more pronounced at each new, higher altitude. Most subjects developed periodic breathing at high altitude but there was a wide variability between subjects as well as variability in the degree of periodic breathing that individual subjects developed at different altitudes. Some subjects developed periodic breathing at even the lowest altitude and this increased with increasing altitude; other subjects developed periodic breathing at one or two altitudes, while four subjects did not develop periodic breathing at any altitude. Ventilatory responses to hypoxia and hypercapnia, measured at sea level before departure to high altitude, was not significantly related to the development of periodic breathing when the group was analysed as a whole. However, when the subjects were grouped according to the steepness of their ventilatory response slopes, there was a pattern of higher amounts of periodic breathing in subjects with steeper ventilatory responses. Chapter 5 reports the findings of an experimental study carried out in the University of California, San Diego, Barcroft Laboratory on White Mountain in California. Seven subjects drove from sea level to 3800m in one day and stayed at this altitude for two nights. On one of the nights the subjects slept using a non-invasive positive pressure device via a face mask and this was found to significantly improve the sleeping oxyhemoglobin saturation. The use of the device was also found to eliminate the symptoms of Acute Mountain Sickness, as measured by the Lake Louise scoring system. This finding appears to confirm the hypothesis that lower oxygen saturation, particularly during sleep, is strongly correlated to the development of Acute Mountain Sickness and may represent a new treatment and prevention strategy for this very common high altitude disorder.

Texto completoWell before the development of severe alcohol-related neurological complications such as Korsakoff’s syndrome (KS), patients with Alcohol Use Disorder (AUD) exhibit variable brain damage and cognitive deficits, as well as sleep disturbances. Although it is well established that sleep contributes to brain and cognitive functioning, its involvement in brain damage and cognitive deficits in AUD remains poorly understood. The objective of this thesis was to investigate subjective and objective sleep quality in AUD and KS patients, and its relationships with brain structure and function. Our results show that sleep complaint must be interpreted with regard to the severity of brain alterations and cognitive impairments in AUD and KS patients. Moreover, we showed a high prevalence of sleep apnea in these patients. REM sleep abnormalities are specifically observed in KS patients and related to the severity of memory deficits. Regarding AUD patients, we highlight the contribution of the severity of withdrawal syndrome in slow wave sleep decrease, and its effects on brain and cognitive functioning. Hence, similarities and differences of sleep architecture have been found in the two clinical forms (AUD and KS). These sleep modifications could depend on the severity of alcohol withdrawal and be involved in the pathophysiology of alcohol-related structural brain damage and cognitive impairment. These results encourage evaluating and managing both alcohol withdrawal and sleep modifications to improve patients’ prognosis at discharge from Addiction department

Background: There is a 10-20% decline in blood pressure (BP) relative to daytime wakefulness during nocturnal sleep (BP dipping) in humans, but some does not have this BP change (BP non-dipping). It has been reported that the non-dipping profile is more prevalent among hypertensive populations, and is a risk factor for cardiovascular disease. However, little is known of the underlying mechanism. We have previously shown that the degree of BP dipping is associated with the sleep-wake cycle and autonomic functioning in normotensive Wistar-Kyoto rats (WKYs). Hypothesis: Spontaneously hypertensive rats (SHRs) with a non-dipping profile have an exaggerated disruption of both autonomic functioning and sleep than do WKYs with a non-dipping profile. Materials and Methods: Polysomnographic recording was performed by telemetry in WKYs and SHRs over 24 hours. We used spectral analysis of heart rate variability as autonomic nervous system activity and analyzed electroencephalogram and electromyogram parameters for sleep structure. BP dipping = systolic BP (SBP) during dark awake (AW) – SBP during light quiet sleep (QS) / SBP during dark AW x 100%. Results: According to the human definition of BP dipping (10%), 26% of WKYs were dippers (≥10% dip) and 74% were non-dippers (<10% dip), whereas in SHRs, 59% were dippers and 41% were non-dippers. Regarding autonomic functioning, both parasympathetic activity and baroreflex sensitivity in sleep during the light period were lower in SHR non-dippers than in WKY non-dippers. Regarding sleep structure, compared with WKY non-dippers, SHR non-dippers spent more time in wakefulness and less time in sleep during the light period and the opposite during the dark period; moreover, delta power% of QS was lower throughout the light-dark cycle. Correlation analysis revealed that vascular sympathetic activity during dark AW and baroreflex sensitivity during light QS were correlated with the BP dipping percentage in WKYs. However, cardiovascular variables did not appear to be related to BP dipping percentage in SHRs. Conclusions: SHR non-dippers have more severe degrees of poor sleep quality and impaired autonomic functioning than do WKY non-dippers, which may account for a higher cardiovascular risk in this population.

Texto completoBackground: Benzodiazepines (BZD) and related drugs are consumed chronically by a large part of the elderly population with chronic insomnia. However, this use in this population is criticized for the risk of associated side effects. Cognitive behavioral therapy for insomnia (CBT-I) is the first-line treatment for insomnia because of its efficacy and safety. Objective: The objective of this project is to assess changes in sleep quality, macroarchitecture and sleep microarchitecture after withdrawal from BZD in the elderly with chronic insomnia. Then, we study the effect of CBT-I coupled with withdrawal on the same variables of interest. We hypothesize that weaning will be accompanied by an improvement in the subjective sleep quality (decrease in Insomnia Severity Index (ISI) and increase in sleep efficiency (SE)) and a modification of certain distinct variables: sleep spindle and stage N3 (increase in the percentage at stage N3 and decrease in the density of sleep spindles). In addition, we hypothesize that these changes will be more pronounced with CBT-I coupled with weaning. Methods: 41 participants (mean age: 69.39 ± 6.88 years) were randomized into 2 groups; stratified for age, duration and dose of BZD and relatives consumed: the weaning+CBT-I group (N = 23) and the weaning group (N = 18). All participants complete a 16-week weaning plan with follow-up, and at the same time, only the therapy group receives CBT-I. Data acquisition is carried out before and after weaning from questionnaire (ISI), sleep diary (SE) over a period of 14 days, and by polysomnographic recordings (stage N3 and density of sleep spindles). Results: 60.98% of participants (weaning+CBT-I group: 60.87%; weaning group: 61.11%) succeeded in completely stopping their medication after withdrawal. A decrease in ISI (F(1.40) = 4.36, p = 0.04) and in sleep spindle density (F(1.36) = 7.18, p = 0.01) was observed after weaning. Finally, CBT-I coupled with weaning showed a greater increase in SE (Sleep Diary; F(1.35) = 6.75, p = 0.01) compared to the control group. Conclusion: The weaning plan with follow-up makes it possible to obtain complete weaning in a majority of participants, without any significant worsening of their quality of sleep being observed. The addition of CBT-I during withdrawal from BZD and related products resulted in a greater improvement in self-reported sleep quality (Sleep Diary: SE).

In this thesis, we proposed the identification and prediction methods of obstructive sleep apnea (OSA), using traditional machine learning and recent deep learning approaches. The human’s physiological signal Electrocardiogram (ECG) was used to identify and predict the occurrence of OSA. The differences of using different architectures were compared. This study is composed of three parts, the first part is the traditional machine learning (ML) identification. The architecture can be divided into signal processing, feature extraction, feature normalization and classification. The features include time domain, frequency domain, EDR (ECG-derived respiratory) waveform and other efficient features such as focusing on the spectra of the baseline wander. The support vector machine was employed in this study to be classifier. The effectiveness of different kinds of feature selector were discussed. The second part is to explore the use of deep learning (DL) architecture. Convolutional Neural Network (CNN) was employed in this study. Both ECG and its Fourier spectrum were used as inputs to and the effects were studied. Both architectures used the Leave-One-Person-Out (LOPO) cross-validation to testify the performance of the classifiers. The third part is about OSA prediction. The ECG signals within 1 to 4 minutes before the occurrence of OSA were analyzed the performance of OSA occurrence prediction by using different system architectures were compared. The Five-Fold cross-validation was employed to test the performance of the methods. The results show that the recognition rate of the first part (Traditional ML) can reach 87.27%, and the second part (Recent DL) which used the time and spectra signals achieved an accuracy of 90.14%. When the Traditional ML and the Recent DL were used in the third part, the best OSA occurrence prediction rate were 71.25% and 96.58% , respectively. Both traditional and deep learning architectures were published in the literatures to identify of sleep apnea and the recognition rate ranged from 82% to 89%. Very few papers were devoted to OSA prediction. Comparatively, this study proposed novel features and deep learning architectures to identify and predict the occurrence of OSA. More reliable cross validation methods were used to testify the performance of classifier. The results showed that the identification rate is significantly higher than the relevant papers and the prediction accuracy is high, which demonstrated the superiority of the proposed identification and prediction architectures in our study. With the impressive results in the identification and prediction of OSA, we ported the model trained by the deep learning frameworks into a real-time OSA detection system. The result demonstrate the possibility of using this approach for medical purpose which to assist the clinical professional in treating OSA an important auxiliary tool.
