Filter by:Post-stroke fatigue (PSF) was defined as 'a subjective feeling of physical and/or mental exhaustion that is unrelated to exertion and does not typically improve with rest'. About 25~85% of first stoke patients had PSF in the first year. Literature review from animal studies suggested the mechanism of post-stroke fatigue may be due to prolonged production of inflammatory cytokines process after stroke. Acupuncture therapy which regulates the inflammatory process may have the potential to ameliorate fatigue symptoms alone with sleep disturbance after stroke. Acupressure which stimulating the same acupoints by manually pressure may make it easy to perform in anytime and anywhere. The effect of circadian based acupressure application on post-stroke fatigue and sleep disturbances need be further examined. The purpose of this two-year study is to (1) explore the distribution of inflammatory cytokines (blood and urine IL-1β, IL-6, TNF-α, IL-8) and post-stroke fatigue and sleep, and (2) examine the effect of circadian-based acupressure application on the inflammatory cytokines (urine and blood IL-1β, IL-6, TNF-α, IL-8), and post-stroke symptoms fatigue and sleep) in ischemic stroke patients with post-stroke fatigue during rehabilitation. Ischemic stroke patients (N=240) will be assessed from the rehabilitation wards. Patients with fatigue (FAS>=24) at assessment (n=78) will be further randomly assigned to the circadian based acupressure application group (AA), or the routine care control group (RC) for 2 weeks. Data of inflammatory cytokines (of IL-1β, IL-6, TNF-α, IL-8), post-stroke fatigue (Fatigue assessment scale), and sleep (Pittsburg Sleep Quality Index and consumer tracker) will be collected. Descriptive statistics, t-test, repeated measure ANOVA, linear/logistic regression or appropriate nonparametric equivalent will be used to compare pre-post differences and to compare differences between groups. Study results will provide information about the mechanism and effect of acupressure application on inflammation and post-stroke fatigue and sleep disturbances in ischemic stroke patients.
The goal of the present clinical descriptive study is to characterize and quantify the potential hormonal chronobiological differences between individuals with type 2 diabetes (T2D) and healthy age and weight-matched controls as either circadian aligned or misaligned. The investigators hypothesize that individuals with T2D have a misaligned and different circadian rhythmicity of circadian biomarkers (melatonin and cortisol) than controls, and that this difference in turn is related to 24h hormonal fluctuations, behaviour, and metabolic-, cardiac-, and cognitive parameters. Participants will be asked to: - fill-out a diary on eating and sleeping habits for 30 days - wear an actigraphy and continuous glucose monitor for 10-14 days - stay overnight at the research facility, including continuous blood sampling and polysomnography
The proposed project aims to disentangle the impact of evening light exposure emitted from tablet devices from the impact of arousing media content on children's sleep regulation, circadian physiology and next-day emotion regulation and executive functioning.
This randomized controlled crossover trial of 36 pregnant individuals with gestational diabetes (GDM) or gestational glucose intolerance (GGI) will: 1. Determine the effects of physical activity (PA) timing, specifically 30 minutes of moderate intensity walking or stepping in the morning (between 5am-9am, within 30-40 minutes of starting breakfast), versus late afternoon/evening (between 4pm-8pm, within 30-40 minutes of dinner) on glucose across the 24-hour cycle. 2. Explore the potential effects of the timing of PA on sleep and mood state.
Disruption of circadian rhythms is frequently observed in patients in the intensive care unit (ICU) and is associated with worse clinical outcomes. The ICU environment presents weak and conflicting timing cues to the circadian clock, including continuous enteral nutrition. The goal of this clinical trial is to evaluate the effect of timing of enteral nutrition on the circadian rhythm in critically ill patients. Patients admitted to the intensive care unit will be allocated to receive either continuous or cyclic daytime (8am to 8 pm) enteral feeding. Differences in circadian rhythms will be assessed by 24h patterns in core body temperature, heart rate variability, melatonin and peripheral clock gene expression. Secondary outcomes include depth of sleep, glucose variability and incidence of feeding intolerance. This study is expected to contribute to the optimalisation of circadian rhythms in the ICU.
Broadly, this study (SCN-BP) seeks to examine sleep and circadian factors that contribute to blood pressure levels at night.
The goal of this study is to learn more about how the time in which participants consume their meals relative to their personalized circadian rhythm influences their overall cardiometabolic health and weight. The investigators are hoping to discover if a circadian-based time restricted eating intervention will improve cardiometabolic health and decrease weight. The protocol is a 46 day prospective cohort study that includes both field and in-laboratory data collection in overweight and obese individuals.
The purpose of this study is to assess the safety and efficacy of Traditional Chinese medicine (TCM) according to Yin Yang theory for treatment of chronic insomnia .
Use huawei wristwatch to record maternal rhythm status and record the VAS score after cesarean section under combined spinal-epidural anesthesia. Based on this study the investigators intend to explore the correlation between maternal circadian rhythm status and postoperative pain after cesarean section.
Surveys indicate that 85% of the adult population consume caffeine on a daily basis. Caffeine acts on sleep homeostatic mechanisms by antagonizing the sleep factor adenosine. Whether and how caffeine also impacts on the circadian regulation of sleep and -wakefulness is fairly unexplored. This study quantifies the influence of regular caffeine intake and its cessation on circadian promotion of sleep and wakefulness, on circadian hormonal markers, well-being, neurobehavioral performance and associated cerebral mechanisms. The knowledge is expected to contribute important insights on recent societal changes in sleep-wake behavior (e.g., shorter sleep duration and delayed sleep phase) and the related increase in people suffering from sleep problems.
