Filter by:Polar stays expose people to extreme climate, isolation and confinement. The combination of these factors induces psychological disorders, sleep disorders, immune and endocrine disturbances, and deficiencies. In the TAAF, (French Southern and Antarctic Lands) two types of population coexist: winter residents, exposed to these stressors over long periods, and country people, who benefit from milder conditions and only make short stays. In this context, the investigators have decided to set up this cohort study with the objective of comparing the state of health of the winterers of the TAAF from 2012 to 2017 with that of the country people of the same period, before their stay, during and the year following their return.
Sleep is a physiological function that plays an essential role in many somatic, cognitive and psychological processes. Although there are many criteria for the effectiveness of sleep, its quantity is unanimously recognized as a major determinant of health. Too little sleep is associated with an increase in metabolic, cardiovascular and accidental morbidity and mortality caused by drowsiness while traveling or at work. Today, the time devoted to sleep is in competition with the time devoted to work, transport or new technologies, in a professional or recreational context. Faced with the public health issues thus raised, research has highlighted the interest of studying the relationships between sleep time and socio-demographic factors, beyond the mere involvement of sleep pathologies. However, among these pathologies, the role of insomnia is not negligible: it is in fact the most frequent sleep disorder (16% of French people in 2010) and represents an important source of involuntary reduction in sleep time, likely to increase inappropriate sleepiness during periods of wakefulness, in the context of activities sometimes involving safety. Flight crews are exposed to specific operational constraints, both in civilian and military environments, which may compromise the sleep recovery function (operational fatigue, extended work amplitudes, repetition of jet lag, etc.). These constraints, which are conducive to compromising the required levels of alertness and cognitive performance, are also at risk of cardiometabolic complications. They therefore raise the issue of risk control and maintenance of air safety. The issue of fatigue in pilots remains an essential issue for the safety of flight operations. Several determinants of operational fatigue in air transport have been identified, such as irregular sleep schedules, large, irregular, and sometimes unpredictable activity amplitudes, sleep debt, night flying, and circadian disruptions related to multiple and repeated time zone changes. While these factors have to deal with rules within airlines that are more often based on "work/rest" than "sleep/wake", current legislation and regulations in the aviation industry are now moving towards scientific approaches to fatigue management in commercial aviation, emphasizing the importance of sleep and taking circadian rhythms into account. In the wake of recent work carried out in the general French population, the conduct of a specific study on sleep time, prevalence and factors associated with chronic insomnia and the complaint of drowsiness among aircrew appears relevant. Due to the specific operational constraints mentioned above, chronic insomnia and sleep debt can be assumed to be more frequent among sailors than in the general population. A better consideration of certain sleep disorders in professional aircrew could allow the adaptation of prevention strategies or countermeasures aimed at optimizing the control of risks with regard to flight safety.
The investigators propose to test the use of pramipexole in patients being treated for Opioid Use Disorder to test its ability to reduce symptoms of both Restless Legs Syndrome and protracted opioid withdrawal and thereby promote initiation, engagement, and retention in treatment.
In the past few years, research has provided evidence for a possibility of dampening immune system by one's will after undergoing a specific training program. Aim of this study was to verity the efficacy in affecting both mind and body by assessing psoriasis activity and psychological functioning. Among the members of both of the groups intensity of skin lesions and pruritus were assessed, consultation regarding treatment took place and multiple questionnaires regarding sleep quality, mindfulness and depressive symptoms were distributed. Blood samples were collected to asses intensity of inflammation, including interleukins.
During the study, designated pressure points before and after one month of splint usage will be evaluated as possible indicators of two different splints efficacy.. Two study groups will be formed. The study will be conducted on patients reporting to the Dental Prosthetics Outpatient Clinic of PUM in Szczecin, Poland. Patients aged 18-65 years with probable bruxism, yet requiring splint therapy will be included in the study.
The investigators aim to determine the effect of suvorexant on actigraphically-derived total sleep time in patients with effectively treated restless legs syndrome with persistent insomnia in a two-arm, double-blind, randomized placebo-controlled crossover 2.5-month trial.
The main goal of this study is to determine whether there is a relationship between fremanezumab's ability to prevent migraine and improved sleep quality in migraine patients (fremanezumab is a FDA-approved humanized CGRP monoclonal antibody for the treatment of migraine). This is a within-person study design that examines treatment effects (changes) using high-resolution assessments. To complete the study, each participant will be observed using daily assessments of migraine and sleep outcomes before treatment (baseline: 0 to 30 days), and at 1, 2, and 3 months after treatment (injection 1: days 31-60, injection 2: days 61-90, injection 3: days 91-120). In essence, this creates an interrupted time-series design where repeated interventions are introduced at fixed intervals.
Current methods for assessing circadian timing require sampling over hours (or even up to a day) while the patient is in controlled conditions. The investigators aim to develop a method that can estimate individual circadian time with a single blood sample taken at any time of the day or night. To do this, the investigators will use two state of the art methods, a plasma proteomics-based method to identify a panel of rhythmic proteins (extending our preliminary data) and a whole blood-derived monocyte-based method using a panel of 15 transcripts (to validate and extend a recent study). We will test both methods in a series of patients with circadian rhythm sleep disorders. We will validate separately the proteomics-based biomarker and the monocyte-based transcript biomarker, and also explore whether combining them can improve the accuracy of our timing estimates. In all cases, circadian phase estimates from the biomarker panels will be compared with those derived from plasma or saliva melatonin (the current "gold-standard" circadian phase marker).
Heart failure (HF) is a common and progressive condition associated with significant morbidity and mortality. Only 25-35% of patients survive 5 years after diagnosis.Sleep disorders are frequently found in this population with up to 94% of patients complaining of sleep disorders. Of these, insomnia and sleep disorders are the most common. The frequency of restless legs syndrome (RLS) varies between 4 and 40% depending on the studies. Patients with HF frequently experience poor sleep quality which is associated with deterioration in quality of life, alertness, and mood. Few studies have examined the prognostic impact of sleep disturbances in this population. A greater morbidity and mortality is observed in the event of poor quality sleep or in the presence of sleep breathing disorders . The investigators therefore propose to evaluate the sleep disorders of patients with HF by self-administered questionnaires, hypothesizing that complaints of poor sleep are linked to a poorer cardiovascular prognosis.
Pain is one of the most common causes of healthcare contact and long-term sick leave, with negative consequences on physical and mental health. Poor sleep is common in chronic pain patients. Epidemiological studies indicate that 5-7% of patients with chronic pain are treated regularly with strong opioids. Negative side effects of pain modulating drugs on sleep quality have been reported, which may have negative influence on overall disease management in chronic pain patients. However, to date there are conflicting results regarding the effects of opioids on sleep, since the pain relieving effect of opioids seem to affect sleep positively. There is data suggesting that physical activity has positive effects on both pain perception and sleep quality (and duration). The aim of the study is to explore insomnia and characteristics of sleep in patients with chronic pain and the relationship with physical activity level and opioid use.
