Active clinical trials for "Chronobiology Disorders"

The specific aims of this studyare to examine the 1) feasibility; 2) acceptability; and 3) preliminary efficacy of a tailored music intervention in home-dwelling older adults with dementia suffering from sleep disruption. Sixty dyads (older adults with dementia and their caregivers) will be randomized to receive the tailored music intervention immediately or following a four week delay.

Cancer related fatigue (CRF) is a stressful and constant tiredness related to cancer and/or its treatment. CRF is the most intense during treatment and can severely interfere with activities of daily living, such as tasks that require physical strength or thinking clearly. Prevalence of CRF has been reported to be as high as 94% during chemotherapy and as high as 34% five years after completion of treatment (Rotonda et al. 2013; Minton & Stone 2008). There is currently no generally-accepted treatment for CRF. However, there is evidence to suggest that light therapy can help with CRF. Non-pharmacological interventions for CRF have also been studied but are costly to implement and involve significant patient burden, particularly among those in active treatment. Given the clinical impact of CRF, the goal of this project is to investigate a novel, low-cost and low-burden intervention for Breast Cancer patients using a particular kind of light treatment called systematic light exposure (sLE) to treat CRF. Two hundred forty-eight breast cancer (BC) patients undergoing adjuvant or neoadjuvant chemotherapy will be recruited from Memorial Sloan Kettering Cancer Center, and City of Hope. The light will be administered by light glasses daily throughout entire duration of chemotherapy. Outcomes will be assessed at eight timepoints during chemo, and a series of follow up assessments at 1 week, 1-month, 3-months and 6-months post-chemotherapy. This study will have major public health relevance as it will determine if an easy-to-deliver, inexpensive, and low patient burden intervention effectively reduces CRF or prevents it from worsening during chemotherapy. Specific Aims: Aim 1: Determine if sLE prevents CRF from worsening in BC patients undergoing chemotherapy Aim 2: Determine whether sLE affects sleep, depression and circadian activity rhythms. Exploratory Aim 3: Investigate sLE normalizes circadian cortisol rhythms. Exploratory Aim 4: Examine whether the effects of sLE on fatigue are moderated/mediated by sleep quality, depression, and/or circadian rhythms.

The mammalian eye serves both visual and non-image-forming functions. New information about the non-image-forming anatomy and physiology of the eye has revealed effects of ocular light stimuli on human circadian rhythms, melatonin suppression, heart rate, pupillary reflexes, cognitive performance, alertness and sleep. The results of the proposed work can be used to make predictions about the effects of light, to make recommendations involving exposure to or avoidance of light, and to design environmental lighting, resulting in improved health and alertness and decreased errors and accidents.

Among the patients with Parkinson's disease, about 40%~50% will suffer from depression, 40% will suffer from anxiety, and 40%~60% will suffer from sleep disorder. These non-motor symptoms of Parkinson's disease will cause great physical and psychological pain and affect the quality of life seriously. Commonly used therapeutic drugs, such as selective serotonin reuptake inhibitor (SSRI) and clonazepam, can cause a variety of side effects, including serotonin syndrome, sexual dysfunction, daytime fatigue, insomnia, residual effects and increased risk of falls. Therefore, a new and more reasonable therapeutic choice should be sought. Agomelatine is a new type of antidepressant with novel mechanism, and can improve sleep structure and circadian rhythm. The aim of this multi-center randomized controlled trial (RCT) is to clarify the role of agomelatine in improving sleep disorders and depression in patients with Parkinson's disease

Circadian clocks are not only found in discrete areas of the brain, but are found in virtually every organ in our bodies, including the heart, lungs and immune system. Disruptions in circadian clocks, or chronopathology, may underlie various forms of cardiovascular, pulmonary, and metabolic disorders. Over the past two decades, molecular geneticists have "cracked" the clock to reveal its core biochemical mechanisms evident in organisms from fruit flies to humans. These mechanistic insights have led to the discovery of links between clock function and an ever-expanding array of prevalent diseases, including heart, lung, metabolic and sleep disorders. Yet the prevalence of circadian disruption in these patient populations is unclear because current tests are not easily applied in clinical settings or have yet to be developed. Here the investigators exploit our newfound understanding of clock mechanisms and the development of new genomic technologies to identify novel complements of clock-regulated genes ("signatures") that will reveal the state of the internal biological clock. This approach will allow us to take a genomic snapshot of clock status from a single blood draw, substantially easing the diagnosis of these individuals with evidence of circadian disruption or misalignment, i.e., chronopathology.

The purpose of this study is to investigate circadian disturbances after breast cancer surgery by means of monitoring sleep and heart-rate variability, by measuring a metabolite of melatonin in urine and by questionnaires and a sleep-diary.

patients 6-25 years old upon diagnostic evaluation will be recruited . study population will comprise of two groups: newly diagnosed IBD patients/ Celiac disease and healthy controls. upon enrollment, subjects will fill out sleeping habits questioners, demographic data, medical history. blood samples will be drawn for CRP and clock gene expression in systemic WBC. intestinal biopsies will be snap frozen for clock gene extraction and amplification only for patients with IBD.

The purpose of this study is to examine, in healthy controls, whether LED lighting that has a color spectrum similar to that of sunlight is able to differentially impact mood, circadian rhythms, sleep, and behavior, as compared to standard fluorescent lighting.

This study evaluates the quality of sleep of patients admitted to medical and intensive care units. All of them will have a clock placed to measure their circadian activity. Also, data will be recorded through questionnaires about the unit, patient habits and medical problems.

The study aims to develop and test a user-friendly, accessible approach to sleep assessment which can function as an initial "triage" of targeted sleep conditions, such as insomnia, insufficient sleep syndrome, sleep apnea syndromes/snoring, and circadian sleep/wake disorders, within the clinical and community population. Specifically, this study will test the validity and reliability of a self-rated, digitized, and cost-effective diagnostic measure with sufficient sensitivity to accurately assess/diagnose common sleep conditions and/or risk for these conditions. Such an approach, would allow for faster assessment of common sleep conditions and disorders, and provide clinical knowledge to the individual, the physician, and if required insurance companies, as to those persons who need more immediate attention or treatment for their sleep condition.
