Filter by:This study will investigate why some people have Obstructive Sleep Apnea (OSA) and how the underlying cause may relate to OSA manifestations (including sleepiness and high blood pressure) and response to different therapeutic approaches (ie CPAP, eszopiclone, and supplemental oxygen). Understanding why someone has OSA could affect how best to treat that individual, but may also have an impact on what problems the disease might cause.
This project is designed to test for the first time whether glucose metabolism is differentially impaired by sleep restriction with and without additional exposure to artificial light at night (ALAN).
The purpose of this study is to better understand specific stress-management practices on mood, sleep, and physiology. Participants will be assigned to one of three interventions (they all active interventions - none are a "wait-list"). Each intervention asks participants to engage in a daily practice of 20 minutes per day for 8 weeks. Questionnaires and measures of heart rate and blood pressure will be collected at the start and end of the 8 weeks, including a virtual laboratory visit.
The investigators are conducting a single center, randomized controlled trial testing the impact of a neonatal sleep intervention, the SNOO, on reducing maternal blood pressure (BP) in the postpartum period in women with hypertensive disorders of pregnancy. The SNOO is a responsive bassinet designed to automatically calm and consolidate infants by responding to their cries. Use of the SNOO has been demonstrated to improve infant sleep by 1-2 hours nightly, thus increasing maternal sleep time. The investigators plan for 110 women with pregnancies complicated by gestational hypertension or pre-eclampsia to be randomized 1:1 to either receive and use the SNOO responsive bassinet for their infants, or to receive the usual care of safe sleep education. Women will be followed longitudinally through 6 months postpartum with serial BPs, weights, mood assessments, and subjective and objective sleep assessments. The investigators hypothesize that for women with pregnancies complicated by gestational hypertension or preeclampsia, that poor maternal sleep quality contributes to increased BP in the postpartum period. The investigators further propose that compared to usual care (safe sleep education), an intervention targeted to improve neonatal sleep (the SNOO), and thus maternal sleep, will improve postpartum BP for these women.
Purpose: The purpose is to determine the effect of therapeutic touch on the sleep quality and anxiety of individuals with chronic obstructive pulmonary disease. Material and methods: This study was conducted between March 2018 and March 2019 as a randomized controlled experimental study conducted with pre-test post-test model. In addition to the routine nursing care, therapeutic touch (TT) and study scales were applied to the experimental group for a total of three sessions, once a day and 10 minutes each, for three consecutive days and only study scales were applied to the control group. The data was collected using Personal Information Form, Richard-Campbell Sleep Questionnaire and State Anxiety Inventory.
In developed countries, the acceleration of the general population ageing has been widely described for decades, involving changes in public health policies. Among the health issues arising from this demographic change, the maintenance of cognitive function will be a major challenge in the next years, both in societal and economic terms. In this regard, some pharmacological and behavioural (e.g. physical activity, social involvement, intellectually demanding activities) preventive approaches have been evaluated to improve cognitive function with ageing. Among them, dietary interventions showed a potential interest to prevent cognitive decline during ageing. In this sense, there is a growing interest to find ecological solutions and to meet major societal challenge the use of microalgae as molecule of interest sources is a recent promising approach. Marine environments harbour a huge biological diversity of microalgae that represents a large source of almost untapped bioactive compounds. This biodiversity comprises 200,000 to 2 million species with about 35,000 which are described and 15,000 maintained in culture collections. Microalgae are able to produce bioactive molecules, such as pigments, fatty acids, peptides and sterols. Some of these compounds are unique and specifically found in the marine environment and they could be increasingly used as natural bioactive products for targeted applications. Fucoxanthin is one of the major carotenoid found in microalgae well known for its neuroprotective effect but to our knowledge no human studies were realized. Thus the objective is to evaluate, in healthy older adults, the effect of a 24-week period of daily supplementation of high and low BrainPhyt, doses on cognitive function parameters (Spatial Working Memory scores, Attention and vigilance, episodic memory, executive function), stress, mood, sleep quality and biomarkers.
Objective: Sympathetic activity starts to increase during exercise. At the end of the exercise, while sympathetic activation decreases, parasympathetic activity increases. Sympathetic and parasympathetic excursions achieve homeostasis. Most of the parasympathetic activity effects are vagus code. It is aimed to compare the comparison of exercise and vagus therapy in these healthy individuals.
The main goal of this study is to determine whether exposure to a narrow band of green light (NBGL) improved sleep quality in healthy subjects. This is a within-subject study design that examines NBGL effects on sleep onset, sleep fractures (i.e., how many times per night the subjects wake up), total sleep duration, and sleep quality using high-resolution assessments. To complete the study, each participant will complete a 30-day, daily sleep diary while using white light (i.e., being in regular room light) during the last 2 hours of their waking period. This period will be defined as the baseline/control arm of the study. After completing this phase 1, subjects will receive a lamp designed to emit the narrow band of green light and again be asked to complete a 30-day, daily sleep diary, but this timer while using the NBGL light (i.e., being in what appears green light) during the last 2 hours of their waking period. This period will be defined as the active arm of the study. After completing this phase 2,
Sleep problems are associated with poor blood glucose control, but current diabetes self-management programs do not include sleep education. This study will randomize participants into two groups: one that receives sleep education and one that does not. The researchers expect both groups to experience reductions in blood glucose. The researchers hypothesize that individuals who receive sleep education as part of their diabetes self-management training will experience greater improvements in blood glucose control, as measured by hemoglobin A1c, compared to the control group.
This is a cross-sectional study with an optional intervention that will examine how extreme sleep durations relate to cardiovascular health, physical activity, and sleep quality by studying three groups of participants: short sleepers (≤ 6 hrs), long sleepers (≥ 9 hrs), and average duration sleepers (7-8 hrs). The optional intervention asks participants to maintain an 8-hour per night regular sleep schedule for one week.
