Filter by:The aim of this study is to assess the impact of 5-hydroxytryptophan (5-HTP) supplementation on sleep quality and gut microbiome composition in older adults with normal cognition vs. mild cognitive impairment (MCI) using a randomized controlled trial.
Investigators will enroll up to 20 participants from 3 Children's Hospital of Philadelphia (CHOP) primary care locations. The primary objective is to determine the whether the Sleep Well! behavioral sleep intervention is feasible to be implemented in primary care offices and acceptable to families. The direction and magnitude of change in child sleep from pre-intervention to post-intervention will also be examined.
The aim of this study is to examine the neurobehavioural responses to two successive cycles of sleep manipulation nights and recovery nights in adolescents, and to determine the benefits of napping on cognitive performance, alertness and mood. Using a split-sleep design, 60 participants, aged 15 to 19 years old, are divided into a nap and a no-nap group. Both groups undergo two cycles of sleep manipulation nights and recovery nights over a period of 15 days. The no-nap group receives an 8-hour sleep opportunity on sleep restriction nights, with no daytime nap opportunity. The nap group receives a 6.5-hour sleep opportunity on sleep restriction nights, and has a 1.5-hour nap opportunity the following afternoon.
Alterations in sleep and the sleep / wake cycle, which are particularly common in Alzheimer's disease patients, could represent an early biomarker for cognitive decline and onset of dementia . Moreover, these disturbances in activity rhythms and sleep patterns represent modifiable factors and therefore potential targets for the prevention of certain neurodegenerative disorders. The main objective of this study will be to test the hypothesis that elderly people without major cognitive impairment who have circadian rhythm disorders of the sleep / wake cycle have structural and / or functional abnormalities in the central nervous system and more specifically of the hippocampal function which could represent a risk factor for the occurrence of cognitive impairment. Indeed, although many studies in both humans and animals suggest the existence of links between sleep alterations and age-related cognitive impairment, the causality of these observations is still not clear. This description of the anatomical and functional substratum of sleep / wake cycle alterations occurring in an elderly population will be based on joint analysis of multimodal brain imaging (MRI) and neuropsychology actimetry data. The SoRyMA-AMImage 3 protocol will correspond to the 2nd actimetry measurement point and the 3rd MRI measurement point of a larger population-based cohort AMImage. This project will collect data from the sleep / wake cycle (actimetry) from a sample of 100 patients included in AMI / AMImage 2 and relate them to brain imaging data (MRI). The main objective of the protocol is the evaluation of the link between changes in sleep and cycle parameters during aging and hippocampal functioning (through fMRI and neuropsychological score of hippocampal dependant tasks). The actimetry variables measured at the two follow-up (4 years apart) will make it possible to measure the degradation of the sleep and cycle parameters (through the reduction of sleep duration, sleep time, increase in sleep fragmentation and decrease in the relative amplitude of the rhythm). This framework will provide access to a very large amount of data that can be cross-referenced with actimetry data; the longitudinal character of this data collected over a decade will also make it possible to work on the evolution of the actimetry parameters and its relationship with the cognitive and clinical evolution of the subjects. Thus, these data will make it possible to study the prognostic value of the analyzed actimetry parameters in association with very complete clinical and neuropsychological data.
The purpose of this study is to evaluate whether undergraduate students completing a course focused entirely on sleep at a major urban university evidence positive changes in their sleep patterns compared to students completing a similar-level course (without any discussion of sleep) in the same department (Psychology) at the same university (UH). Potential changes in sleep patterns across the semester will be examined as well as whether putative changes in sleep can be linked with academic and mental health outcomes.
Presented as an online survey, this study seeks to better understand how Thorne customers are using and experiencing the new Hemp Oil + product and how they feel it compares in the marketplace. Hemp Oil + is a combination product with a proprietary blend of hemp, clove, black pepper, hops, and rosemary extracts. People who have independently elected to purchase and use Hemp Oil + before the study starts will be invited to voluntarily participate. If they meet study requirements and give consent they will answer questions online about their experience with Hemp Oil +. Questions address general demographics and wellness, general impressions of the product, how it compares to other products, and any effect it has had on their gastrointestinal health, physical discomfort, sleep, and mood. The survey is expected to take 15-30 min of participant time. Data will be analyzed to determine whether the customer experience with Hemp Oil + is as favorable as it seems from anecdotal reports. Analysis will also be conducted to find patterns that can inform future studies, marketing, and customer education efforts.
The investigators hypothesize that chronic insufficient sleep is associated with diminished endothelium-dependent nitric oxide-mediated vasodilation and endothelial tissue-type plasminogen activator release in adults with elevated blood pressure. Furthermore, the investigators hypothesize that the postulated diminishment in endothelial vasodilator and fibrinolytic function with insufficient sleep will be due, at least in part, to increased oxidative stress. Furthermore, increasing sleep duration and improving sleep quality will increase both endothelium-dependent nitric oxide-mediated vasodilation and endothelial tissue-type plasminogen activator release in adults with elevated blood pressure. Increases in endothelial vasodilator and fibrinolytic function will be due, at least in part, to reduced oxidative stress.
The aim of this study was to compare the depression and sleep disturbances of operated endometriosis patients before and after the operation. The main objective here is to provide data on how patients' psychological states and sleep patterns are affected by the symptoms of endometriosis and how these effects can be corrected. In this way, it is aimed to determine whether the patients have psychological support needs and to give the planned treatment due to endometriosis in the early period. As a secondary goal, it is planned to keep the patients in follow-up with their improved sleep and psychological conditions, and to improve their adherence to treatment and quality of life.
The researchers' implement and measure the effects of a singing group intervention program for older adults, with an RCT design, in a natural context, on the health, well-being and cognitive function of older adults.
The aim of this trial is to evaluate the efficacy of an intervention (delivered through a smartphone) for improving the mood, physical activity, and sleep of medical interns.
