Filter by:A drop off in improvement over the months and years after treatment is common. One contributor may be poor memory for the contents of treatment. This study seeks to determine whether text messages containing reminders of the content of sessions will improve treatment outcomes.
Light exposure is on the rise in recent years. In large part because of unintentional illumination from screens that emit light directly into the eyes. Millions of computers, tablets, televisions, and smart-phones are sold worldwide every month and the usage time of these devices is increasing constantly. Today, people are exposed to ongoing light exposure from these device screens, emitting short wave length (SWL) during day and night hours, whether as active or passive users. In sum, artificial light at night (ALAN) seem to affect human circadian rhythmicity (melatonin and thermoregulation) and sleep, with two major factors. First, wavelength of light, with SWL being most detrimental to sleep and rhythms, when compared to LWL (Brianard et al., 2001). Second, a dose-response relationship exists between increasing light intensity and poorer sleep/circadian rhythms (Brianard et al., 1988; West et al., 2011). Based on existing knowledge, we hypothesize that when compared to long wavelength LWL illumination, short wavelength SWL illumination from computer screen will have a more damaging effect on melatonin (MLT) production and secretion, interfering body temperature regulation and affecting sleep quality, efficiency and sleep architecture. In addition, we hypothesized that intensity of the screen illumination will play another important factor on these outcomes, we assume that high intensity compared to low intensity will have more damaging effect on: melatonin, thermoregulation and sleep.
The purpose of this study is to determine the effects of morning bright light therapy on fatigue, sleep disturbances, and circadian activity rhythms in lung cancer survivors.
Purpose: To evaluate the influence of probiotic supplementation on body composition and other markers of health in occupational shift-workers. Participants: Healthy, overweight females (ages 22-55 yrs) who are employed on a shift-working schedule. Procedures (methods): In a randomized, placebo-controlled intervention, subjects will complete 3 different testing sessions (pre-screening, 1 baseline, 1 post-testing session) as well as a 6-week intervention period. Prescreening will include written informed consent, a health history questionnaire, baseline anthropometric measures, assessment of resting heart rate, and exercise protocol familiarization. Baseline testing will involve body composition, a fasted blood draw, mood surveys, and an exercise treadmill test. Subjects will be randomized to a treatment group (multi-strain probiotic or placebo) for 6 weeks of supplementation that includes 2 electronic contacts, followed by post-testing that will occur in the same fashion as baseline testing.
The purpose of the study is to demonstrate that continuous apomorphine treatment during the night compared with placebo improves sleep quality in insomniac patient with Parkinson's disease.
Sleep disturbance is a significant issue in people undergoing dialysis. More than 80% of haemodialysis patients complain of difficulty sleeping. Inadequate sleep can cause poor daytime function and increased risk of motor vehicle incidents. One of the common reasons for sleep disturbance in dialysis patients is sleep apnoea. Sleep apnoea involves pauses in breathing that occur during sleep. Each pause can last only a few seconds or minutes. Severe sleep apnoea reduces oxygen supply and increases risk of heart attack and stroke, which are the leading causes of death in dialysis patients. In this project, the investigators will examine how a change of dialysis treatment might improve sleep. This project will first identify patients at risk of sleep disturbance using surveys and a subsequent sleep study. The investigators will then test different dialysis models to see the effect of dialysis treatment on sleep apnoea. The aim is to find a dialysis model that works better for patients with sleep apnoea.
Background: People who have had a traumatic brain injury (TBI) often have trouble sleeping. TBI may also alter hormones, which can cause poor sleep. Researchers believe that a form of growth hormone releasing hormone (GHRH) might improve sleep in service members and veterans who have had a TBI. Objective: To see if GHRH can improve sleep in people who have had a TBI. Eligibility: Active duty service members or veterans (active duty in the past 10 years) ages 18-45 who have had a TBI in the past 6 months to 10 years. Design: Participants will be screened with: Medical history Physical exam Blood and urine tests Getting ACTH (a hormone) through an intravenous catheter (thin plastic tube) Interview about their mood and alcohol and drug use Questionnaires about their TBI, mood, and sleep Participants will have 2 overnight study visits a couple weeks apart. These will include: Physical exam Urine sample Two intravenous catheters placed. Blood samples will be taken throughout the night. Two shots under the skin of the belly. The shots will be GHRH on one visit and placebo on the other. Spending the night in the sleep lab. Their brain waves will be recorded with electrodes placed on the scalp. A questionnaire in the morning about their sleep Participants will be called a few days after each overnight visit. They will be asked about how they are feeling and to rate their sleep.
The purpose of this study will to be to evaluate the effects of a mobile intervention focused on improving the chronic disease self management skills of individuals with low health literacy. The intervention will provide information that culturally and linguistically tailored to participants' level of health literacy.
Non Rapid Eye Movement (NREM) sleep parasomnias (sleepwalking and sleep terrors) are frequent and disabling sleep disorders characterized by arousal specifically from slow wave sleep (SWS) with dissociated brain activity that may be related to lower nociceptive state. The investigators recently reported frequent subjective complaints of chronic pain, migraine and headache during wakefulness in adult sleepwalkers. They also described frequent analgesia during severe and injuring episodes, suggesting a relationship between dissociated brain activity and nociceptive dysregulation. However, this study did not included objective nociceptive measures and the retrospective assessment of perceived pain during parasomnia episodes over a lifetime span might also introduce a recall bias. The aims of the present study are to measure objective pain sensitivity in patients with NREM parasomnias and matched controls during 1) parasomniac episodes, 2) light NREM sleep and SWS, and 3) wakefulness. Fifteen adults with severe NREM parasomnia and 15 age and sex-matched controls will be recruited. A 25 hours (8 AM to 9 AM) sleep deprivation protocol followed by auditory stimulations during SWS will be used to trigger parasomniac episodes. Thermoalgic stimulations of graduate intensity will be applied during wakefulness (8 PM) to determine the nociceptive threshold. During the recovery sleep following the sleep deprivation, the investigators will apply repeated subthreshold thermoalgic stimulations in NREM stage 2, SWS and triggered parasomniac episodes and report the behavioural/neurophysiologic nociceptive responses. The investigators hypothesized a lower nociceptive threshold during wakefulness in sleepwalkers and a decrease of the arousabiliy during SWS and parasomniac episodes. This study may help to better understand the etiology and mechanisms underlying the clinical enigma of the nociceptive dysregulation in NREM sleep parasomnias.
The purpose of this research is to test the hypothesis that those with non-traditional work schedules (e.g. shift workers) have a higher cardio-metabolic risk than those with traditional work schedules (e.g. day workers), and that both accumulated sleep debt and the degree of circadian disruption predict the elevated cardio-metabolic risk. The findings of this research are expected to increase our understanding of physiologic tolerance to non-traditional work schedules and provide the basis for the development of methods for the early detection of adverse health effects and determine coping strategies for the millions of workers with non-traditional work schedules.
