Filter by:Patients with multiple sclerosis (MS) struggle on a daily basis with accompanying, "Invisible" symptoms like primary fatigue, pain and emotional-cognitive disorders. With the disease progression, these symptoms only intensify, and in combination with basic physical symptoms, quality of life (QOL) rapidly decreases. An important goal of researchers and clinicians involves improving the QOL of individuals with MS, and the exercise therapy represents potentially modifiable behavior that positively impacts on pathogenesis of MS and these "Invisible" symptoms, thus improving the QOL. However, the main barrier for its application is low motivational level that MS patients experience due to fatigue with adjacent reduced exercise tolerability and mobility, and muscle weakness. Getting individuals with MS motivated to engage in continuous physical activity may be particularly difficult and challenging, especially those with severe disability or Expanded Disability Status Scale (EDSS 6-8). Till now, researchers have focused their attention mainly on the moderate or vigorous intensity of exercise and on cardiorespiratory training in MS patients to achieve improvements in daily life quality, less indicating the exercise content, and most importantly, breathing exercises. In addition, it is investigators intention to make exercise for MS patients more applicable and accessible, motivational and easier, but most important, productive. Investigators think that MS patients experience more stress with aerobic exercise or moderate to high intensity program exercise, and can hardly keep continuum including endurance exercise, or treadmill. Hypothesis: Investigators hypothesis is that 8-weeks of continuous low demanding or mild exercise program with the accent on breathing exercise can attenuate primary fatigue, pain, headaches, emotional-cognitive and sleep dysfunctions in MS patients and provide maintenance of exercise motivation. Investigators also propose that important assistant factor for final goal achievement is social and mental support of the exercise group (EDSS from 0-8) led by a physiotherapist. This will help to maintain exercise motivation and finally make better psychophysical functioning, and thus better QOL.
It is recommended by the American College of Obstetricians and Gynecologists' Committee on Obstetric Practice that all obstetricians screen each women for postpartum depression and anxiety with a validated instrument. Although much effort is made, the contributing factors still lack in the literature due to its multi-factorial nature and complexity. In addition, the effects of prenatal education classes remain understudied. Therefore, this study aims to demonstrate the prevalence, characteristics and contributing factors of the postpartum depression. In addition, the change in prevalence and characteristics of the postpartum depression among women who had prenatal classes and not will also be assessed.
Sleep disorders and disturbances are mostly underestimated in clinical practice. Moreover, this problem is generally neglected by the pregnant themselves. Today, it is important to underline any problem that may have an affect to improve the quality of life during pregnancy. This study assesses the sleep quality, insomnia patterns and obstructive sleep apnea in the second and third trimesters of pregnancy.
Obstructive sleep apnoea (OSA) is characterised by recurrent nocturnal respiratory interruptions, resulting from the total or partial collapse of the upper respiratory ways. This results into sleep fragmentation, metabolic and biological disorders, which alter the neuropsychological and cardiovascular systems. Nowadays, 24% of men and 9% of women aged 30 to 60 years disclose already an asymptomatic and underdiagnosed sleep disorder breathing (SDB). In subjects suffering from cardiovascular disease, prevalence of SDB is higher than in the general population, reaching 87% in people with resistant hypertension, 51% in those with heart failure and 62% in those with atrial fibrillation (to cite a few).The current diagnostic tool for SDB is polysomnography (PSG), but this is an expensive, time-consuming and uncomfortable tool, which limits its wide-spread use despite the high frequency of SDB in general and, even more, in patients suffering from cardiovascular diseases. Several screening devices exist in order to test those patients at risk of SDB, but these have several limitations, since they are not recommended in patients who are asymptomatic for apnoea, in those with cardiorespiratory diseases, nocturnal arrhythmias or neurological and metabolic co-morbidities. In other words, nowadays there isn't an efficient screening tool of SDB, mainly for those with a low pre-test probability of having SDB. Preliminary evidence suggests that the seismocardiography (SCG) and the ballistocardiography (BCG) can detect nocturnal awakening and sleep disturbances with a good sensitivity and accuracy as compared to the state-of-the-art PSG. Simultaneous recording of SCG and BCG is called kinocardiography (KCG) and has not been performed yet during sleep. The main hypothesis tested in this study is that the KCG provides sensitive and accurate measures of obstructive and central apnoea as compared to the state-of-the-art PSG. The secondary hypotheses are related to modifications in the SCG and BCG signals during the apnoea and the effects of continuous positive air pressure (CPAP) therapy. These hypotheses will be tested through a series of studies in normal volunteers and patients, as follow: - Group RESPIRATOIRYSIMUL (Study A): voluntary end-expiratory breathing cessations periods and obstructive voluntary apnoea's (n=46); - Group SBD (Study B): patients admitted for complains of sleep disturbances without cardiovascular and/or respiratory abnormalities which could induce artifacts in the KCG recording (n=50); - Group nCPAP (Study C): patients treated by nCPAP therapy (n=50); - Group UNSELECTED (Study D): unselected consecutive patients (n=100), without recruitment restrictions. Study A is an interventional study on voluntary breath holding in normal volunteers. Studies B, C and D are observational investigations recruiting subjects referred for PSG as required by their medical condition. Because the KCG device is not intrusive, the investigators do not anticipate difficulties in the enrollment. This study will not affect in any manner the regular medical care of the patients admitted to the sleep laboratory. To conclude, SDB is a widespread disease with detrimental health effects and its prevalence is supposed to increase in future years. PSG is the gold standard for diagnosis of SDB but it is an expensive, uncomfortable and time-consuming tool, limiting its use in daily clinical practice. For subjects with a high pre-test probability of SDB, portable, inexpensive and easy-to-use tools have been proposed as sleep monitoring and seem to provide accurate estimates of SDB. Although such devices seem promising, they disclose also several limitations and are not universally accepted as SDB screening devices, mainly in case of low pre-test probability of SBD. The less cumbersome KCG may screen patients for SDB accurately. One of its unique features is also that it can directly identify the consequences of SDB and nCPAP therapy on the cardiovascular system, and in especially the presence of frequently associated cardiac arrhythmias. With a more efficient pre-screening, those who are most likely to be eligible for nCPAP therapy will have a better access to the currently existing sleep laboratory facilities. The present research project has thus the potential of improving SDB patients care and health, at no additional societal costs.
The present project is aimed to contribute with new knowledge concerning how light conditions in the physical environment can be manipulated to alter the sleep and circadian rhythms of individuals with an evening-type circadian rhythm. More precisely, the study will explore whether exposure to blue light (compared to a full spectrum light control condition) during the morning hours advance the circadian rhythms of evening-type individuals, towards that which is more similar to the daily rhythm of morning-type individuals. This study is important as it has been found that evening-type adolescents and adults are at higher risk of poor academic performance and demonstrate lower intellectual performance when tested at their nonoptimal early times of day, and given the fact that most schools and workplaces structure their working hours during such early hours of the day. Such an intervention could thus help evening-type individuals better adjust to the different early day requirements that they are exposed to. The project involves a three-day intervention where participants will be exposed to blue monochromatic light, administered through ceiling mounted light emitting diode (LED)-based room lighting, in the early hours of each morning for a duration of 60 min. The participants' sleep, circadian rhythm and waking function will be assessed both objectively and subjectively. The effects of the intervention are transferable to real life educational and work settings and can thus be applied in naturalistic settings. The intervention is based on the new laboratory infrastructure available at the sleep laboratory situated in Christies gate 12.

This study is aimed to find out Sleep profile differences in children and adolescents with and without ADHD,Relationship between sleep profile disturbance and ADHD symptoms, Impact of sleep disturbance on cognition functions and quality of life.
This study compares the titration pressures achieved through two auto-titrating modalities, a new incremental fixed pressure mode versus routine auto-adjusting pressure mode, in CPAP-naïve obstructive sleep apnea patients. The aim of the study is to verify that this new modality achieves a lower titration pressure.
Sleep disruptions are prevalent complaints in cocaine use disorder (CUD) subjects, either during consumption or withdrawal. Repetitive transcranial magnetic stimulation (rTMS) seem to be a promissing strategy in the treatment of chronic cocaine users. The aim of this study will be to assess the variation on self-perceived sleep quality and drug use variables in individuals with CUD undergoing a rTMS protocol over the left dorsolateral prefrontal cortex (DLPFC).
