Filter by:The purpose of this study is to determine whether a modified yoga program helps improve pain and function in elders age 65 years or older living in an assisted living community. Participation in regular physical activity, such as yoga, may improve strength and mobility and decrease pain. This study was developed to ascertain whether a modified yoga program improves pain and function in assisted-living elders, age 65 years and older.
Sleep leads to consolidation of learning in humans, restoring memories that were forgotten over a waking day and protecting memories against future forgetting. Although theories of consolidation have linked sleep spindles seen on electroencephalography to consolidation due to their putative role in hippocampal transfer to the neocortex (Antony et al, 2019; Antony & Paller, 2017), spindles have not yet been linked to consolidation of perceptual learning or generalized learning. Prior research by a collaborator on this project has shown that sleep specifically aids in the consolidation of generalized perceptual learning of speech (Fenn, Nusbaum, & Margoliash, 2003). Subjects show a 10-point reduction in performance after a waking retention period, while no loss is found after a retention period containing sleep (Fenn et al., 2003). Various measurable activities in the brain are associated with memory consolidation during sleep. This project intends study the effect of dexmedetomidine on memory consolidation during sleep Hypothesis 1 The gain in perceptual learning after a 90 minute natural sleep nap will also occur after 90 minutes of a sufficient dose of IV dexmedetomidine to replicate sleep. This result would suggest that consolidation can occur under this anesthetic state of consciousness. Hypothesis 2 The number and quality of sleep spindles seen on EEG in subjects administered dexmedetomidine will correlate with this gain in perceptual learning. This result would suggest that biomimetic sleep spindles are sufficient for producing memory consolidation. Only those subjects capable of giving their own consent will be considered for this study. The study will enroll 20 healthy subjects for this study between the ages of 18 and 35. All volunteers will be fit and healthy, meeting the American Society of Anesthesiologists (ASA) physical status classification ASA 1 (normal healthy subjects) and ASA 2 (stable chronic condition) and of normal body habitus. Prior to the study enrollment, each volunteer will sign an informed consent form. A standard anesthetic medical history will be taken in addition to performing a focused standard pre-anesthetic physical examination in order to rule out active and chronic medical problems.
Subjects will complete an electronic consent form and then fill out questionnaires on a tablet computer. The answers to the questions will be recorded to a secure electronic database, along with the results of a clinical overnight sleep study performed separately from this research study (this research study will not perform any overnight visits). After the overnight study diagnosis researchers will see which answers are most commonly given in association with each diagnosis. In addition, we will assess to what extent the sleep disorder impacts the patient's perception of his/her quality of life.
There is evidence that survivors of childhood cancer have a high prevalence of poor sleep, including symptoms of insomnia. Insomnia is highly comorbid and has been associated with impaired cognitive performance, a range of psychiatric disorders, cardiovascular disease, and reduced quality of life. However, we still lack knowledge about the direct impact of available internet-based insomnia treatment programs for survivors of childhood cancer experiencing insomnia, in addition to how improving insomnia symptoms impacts neurocognitive function and late health morbidities in this population. Therefore, in this study, we will utilize the resources available in the Childhood Cancer Survivor Study (CCSS) to use an accepted, established, efficacious internet-delivered CBTi insomnia treatment program and evaluate the efficacy of this program in adult survivors of childhood cancer. Positive results from this study and our use of an internet-based intervention are likely generalizable and be scalable to the large and geographically diverse population of childhood cancer survivors with chronic health conditions. Primary Objective To examine the efficacy of an eHealth intervention for improving symptoms of insomnia among adult survivors of childhood cancer. Secondary Objectives To examine the impact of an eHealth intervention for insomnia on the clinical severity of insomnia symptoms in adult survivors of childhood cancer. To determine whether treatment of insomnia symptoms will improve neurocognitive function in adult survivors of childhood cancer with both insomnia and neurocognitive impairment. To explore the mediating effects of improved neurocognitive function, emotional distress, and cardiovascular health on the association between insomnia symptoms and quality of life.
Sleep changes rapidly during the first year of life. Brain maturation is accompanied by sleep consolidation in several episode during day and night (daytime naps and night sleep) and progressive organization during the 24h period (more wake during day et more sleep during night). In the first months of life, sleep episodes are frequently interrupted by wake, possibly induced by multiple external and internal stimuli. One of this stimulus could be bladder voiding that is particularly frequent in babies. Only one team worked on the link between sleep and bladder voiding and reported that bladder voiding was associated with cortical arousal during a daytime nap in a little group of babies. In this study, investigators propose to study the relationship between sleep and bladder voiding in a bigger group of infant and during daytime but also nighttime sleep.
Resident wellness and physician burnout are under the spotlight more and more as data begins to show that there is a point of diminishing return on the number of hours in training. In 2003, resident work hours were restricted to less than 80 hours per week averaged over 4 weeks. This change was implemented in response to the robust body of evidence that increased work hours leads to decreased sleep, which in turn leads to medical errors and depression. These factors directly and indirectly lead to worse outcomes for patients. In residency, it is difficult objectively to assess when residents are beginning to experience burnout and depression. The investigators propose a study to determine whether tracking of certain heart rate parameters (resting heart rate and heart rate variability) as well as sleep can correlate to subjective assessment of resident wellness, burnout and depression. The investigators will also compare these measures to biomarkers of stress, such as salivary cortisol. The results of this study may lead to improved understanding of what truly causes burnout and may be an eventual target for intervention to help improve short- and long-term outcomes for resident physicians as well as their patients.
Participants will download a phone-tracking app for a week to track phone usage, providing objective data on usage patterns. Quantitative tasks and questionnaires will also be carried out before and after the tracking period.
The goal of the study is to test the role of telemedicine combined with humidification to check CPAP treatment during the first month to improve adherence and reduce unsolved side effects of therapy.
This is a pilot, prospective, randomized controlled trial of a novel sleep health program versus no sleep intervention in chronic pain patients. The Sleep Health program will consist of weekly home-based videos and digital materials termed "Self-Management for Sleep Care", which will provide participants with information on how to improve their sleep through education on sleep hygiene, relaxation training, and cognitive behavioural components. Patients will be also be screened through undiagnosed sleep apnea. For those determined to have suspected undiagnosed moderate or severe sleep apnea, they will be receive a recommendation for referral to a sleep clinic as part of standard of care. The study aims to evaluate the feasibility and effectiveness of the Sleep Health Program which includes the videos and digital materials and screening for sleep apnea in patients with chronic pain.
The investigators will aim to determine the association of mood disorders (MDO) with preclinical and clinical cardiovascular (CVD) risk factors among children. The investigators will also aim to identify traditional and non traditional predictors of CVD risk among children with MDO.
