Filter by:Patients with chronic pain who use opioids appear to be at increased risk for breathing issues during sleep, termed sleep disordered breathing (SDB). Treatment of SDB often consists of use of a device during sleep that provides continuous positive airway pressure (CPAP) via a mask interface. The goal of this study is to determine whether patients with chronic pain who use opioids and have SDB might benefit from the use of CPAP in terms of sleep quality, pain, quality of life, and other measures. In addition, the study will examine whether these individuals are able to adhere to CPAP, which will be important for future studies. Lastly, we anticipate that CPAP won't work for everyone due to the changes that opioids can cause in breathing patterns. We will examine how often CPAP is ineffective, and whether we can predict which individuals are least likely to resolve their SDB with CPAP.
The aim of this research is to determine the effect of foot reflexology applied to primiparous women who had cesarean section in the postpartum period on pain, fatigue, sleep quality and lactation. This research is a randomized controlled trial. The study was conducted in Şanlıurfa, which has the highest fertility rate in Turkey.
This research aims to determine the effect of acupressure applied to nurses actively working in internal clinics on sleep quality and fatigue during the COVID-19 pandemic process. This research hypothesizes that acupressure improves sleep quality and reduces fatigue.
Circadian clocks shift later (delay) with the progression of puberty; this shift contributes to late sleep onsets in older adolescents. Early school start times, however, force teenagers to awaken earlier than their spontaneous wake time and the opportunity for sleep shortens. Chronic circadian misalignment and sleep restriction are at their peak during late adolescence, and are associated with various negative outcomes. Morning bright light exposure from light boxes can shift rhythms earlier (phase advance) to facilitate earlier sleep onset, and reduce circadian misalignment and the associated risks. Studies of adults, however, indicate that restricted sleep and exposure to evening light due to late bedtimes make morning bright light less effective in producing advances. Pilot data collected from adolescents mimic this finding, but also suggest that staying awake late in normal household lighting and the subsequent sleep restriction before and during a 3-day morning bright light regimen, can shift the system in the wrong direction (phase delay). The overarching goal of this study is to examine the dose of sleep restriction and evening household light that prevents the desired phase advance to morning bright light in adolescents aged 14-17 years. Study 1 aims to construct a sleep restriction with normal household evening light dose-response curve to determine the point at which morning bright light begins to lose its effectiveness. The investigators hypothesize that the circadian system will advance with sufficient sleep, but with increasing sleep restriction/evening light, circadian rhythms will not shift or will delay despite the phase advancing morning bright light. Study 2 will test whether reducing evening light exposure by wearing sunglasses before bedtime during sleep restriction can facilitate phase advances. The main outcome measures to build the dose-response curve will be phase shifts of the central circadian clock marked by the dim light melatonin onset (DLMO) and total sleep time measured from actigraphy in the laboratory. Secondary outcomes include cognitive performance, sleepiness, and mood.
Objective: The aim of this study is to investigate the effectiveness of Chiropractic care on pain, quality of life and sleep in pregnant women compared to a control group. The study is designed as non-randomized controlled trial. Forty-two pregnant women at least on the 14th week of gestation will be included. Control group will include women receiving regular care, but no chiropractic care. Care will extend for 4 weeks. Outcomes measures include sleep quality, pain and quality of life questionnaires.
The lockdowns and restrictions associated with the COVID-19 have created a seismic shift in where work is done. Prior to the pandemic, approximately 20% of individuals were working from home while during the pandemic, more than 70% of individuals worked from home. While it is unlikely that such a large percent of the population will remain working from home, the vast support from workers for such work arrangements and the potential increase in productivity means that there will likely be a revision of the work place with more individuals working from a home office environment than have done so in the past. One unintended aspect of working from home is a reduction in light exposure, especially in the contrast between the daytime and evening. Offices converted from bedrooms, basements, and kitchens are often illuminated in the recommended 50-100 lux range, as opposed to the approximately 500 lux of most offices. While this light intensity is sufficient to work or read by, it may be insufficient to maintain adequate mental and physical health. In addition to light allowing us to consciously perceive the world around us, light can also induce a variety of changes in physiology that can impact our health, notably inducing shifts in the timing of circadian rhythms, suppressing the onset of melatonin production, and increasing alertness with subsequent changes to sleep latency and architecture. These changes in sleep and circadian rhythms have been associated with a variety of pathologies including increased risk of metabolic, psychiatric, cognitive, and cardiovascular disorders, in addition to overall longevity. Development of an adequate prophylactic countermeasure for the circadian desynchrony to which home office workers are exposed is a critical step in maintaining the health of these individuals. There are two main studies. The first study (Years 1-2) will be an in-laboratory determination of the threshold of light needed to minimize the negative impact of nocturnal light exposure. The second study (Years 3-4) will be a field study applying this threshold to determine if whether in situ use of this light intensity during the day improves health and safety among home office workers. Current CT.gov represents the second part of this study i.e. "Study 2: The Impact of Daytime Light Intensity in Home Workplaces on Health and Well-being". In study 2, investigators will examine a series of participants (N=36), each of whom will participate in a five-week experiment. Each participant will have a screening visit at their home. The study will be conducted over five successive one-week periods with two cohorts of participants experiencing the same series of lighting interventions. All data collection will be performed during the working days (Monday - Friday) when participants are exposed to the lighting in their home offices.
The purpose of this study is to systematically examine the impact of different intensities of daytime light and the subsequent impact that such exposure has on non-image forming responses to light in the evening.
This study aims to characterise associations between day-to-day sleep, activity, meal schedules, well-being and continuous glucose profiles in a cohort of free-living healthy, young adults. Multi-day data will be collected using wearables and smartphone-based measures in field settings.
The hiSG Sleep Health Study seeks to investigate the efficacy of education + goal-based programmes for the promotion of healthy sleep habits and to evaluate its impact on daytime sleepiness and mental health.
Hypothesis: Veterans with PTSD prescribed clonidine will demonstrate improvements in PTSD symptoms, including daytime, nighttime, and sleep-related behaviors.
