Background: Obstructive sleep apnea (OSA) occurs when the blockage of the airway causes a person to stop breathing involuntarily for 10 seconds or more throughout the night during sleep. Pediatric OSA can be especially concerning and can have long-term effects. Researchers want to see how a monitoring device called near-infrared spectroscopy (NIRS) compares with the traditional techniques used in children s sleep studies. Objective: To learn about oxygen levels in the brain and limbs in children with and without sleep apnea using a wearable, point-of-care biosensor. Eligibility: Children aged 3-12 who have OSA and plan to receive treatment (OSA group) or who do not have OSA (NORM group). Design: Participants will be screened with a review of their medical records. If they have taken part in other NIH studies, that data will be reviewed as well. Participants in the NORM group will have 1 overnight study visit. Those in the OSA group will have 2 overnight study visits. Participants will do an overnight sleep study. They will have a physical exam and medical history. They will have a sleep study electroencephalography (EEG). For this, electrodes will be placed on their head. They will wear a gauze cap to keep the electrodes in place. Two NIRS probes made of a soft silicon will be placed on their forehead and arm. They will follow their normal bedtime routine. Their parent will stay overnight. The OSA group will have a second study visit 2 weeks to 12 months after they start treatment for their sleep apnea. They will repeat the sleep study.

Insomnia is one of the most common sleep disorders and affects approximately 10 - 40% of the population across different age groups in Hong Kong. Cognitive behavioral therapy for insomnia (CBT-I) is the first line treatment for adult insomnia due to its comparable effect to medication in short term but is more sustainable in the long run. However, only a few sufferers have received CBT-I, due to limited accessibility, lack of trained sleep therapists, time costing and geographical limitations. To increase CBT-I accessibility, different formats of CBT-I have been proposed. Empirical evidence including ours consistently suggested that self-help digital CBT-I is effective in improving sleep while its augmentation with a guided approach could further enhance the treatment gain. Previous evidence has suggested that although self-help CBT-I could lead to positive outcomes, the drop out rate is quite high and maybe less effective for patients with comorbidity or high level of distress. Thus, a stepped-care approach to CBT-I that utilizes online self help and therapist-guided modes of delivery might be a potential way to facilitate efficient dissemination of effective insomnia treatment resources. The effectiveness of the stepped care model will be evaluated in a real world setting using stepped-wedge cluster randomized controlled design. The program will be rolled out to different districts in Hong Kong sequentially in 18 districts over 4 steps with a eqaully spaced time periods.
NCT06655649
Obstructive Sleep Apnea (OSA) is a common medical disorder that is associated with reduced quality of life and higher risk of cardiovascular disease. Treatments for OSA and limited and not well tolerated. Our lab has shown that a low carbohydrate, high fat ketogenic diet (KD) can reduce OSA severity. Since it can be challenging to adhere to a ketogenic diet, the investigators propose that ingesting exogenous ketones can be an alternative method to improve OSA. Specifically the investigators will examine the effect of taking a commercially available product (Ketone-IQ) at bedtime on overnight ketones and sleep quality. The investigators will also examine the effect of Ketone-IQ on sleep apnea severity, compared to placebo. This project will examine the pharmacokinetics, tolerability, and sleep impacts of ingesting exogenous ketones before sleep in patients with sleep apnea, while under treatment for OSA. \[Aim 2: Examine the preliminary efficacy of ingesting exogenous ketones before sleep on OSA\]

The purpose of this randomized clinical trial is to characterize the effects of two exercise interventions, high-intensity interval training (HIIT) and continuous moderate-intensity exercise (CME), on sleep and inflammation in older people living with HIV (PWH). This study is a sub-study associated with The High Intensity Exercise Study to Attenuate Limitations and Train Habits in Older Adults with HIV (HEALTH-HIV; NCT04550676). The investigators propose the following aims: Aim 1. Compare the effectiveness of HIIT and CME exercise interventions on sleep in older PWH. Aim 2. Quantify inflammation markers associated with sleep quality (self-report surveys) in older PWH at baseline, between (week 8) and after exercise interventions (HIIT and CME) (week 16). The investigators hypothesize HIIT will lead to greater improvement in sleep quality (duration and quality) compared to CME and older PWH who experience poor sleep quality and the CME intervention will have increased inflammation markers compared to older PWH who experience better sleep quality and the HIIT intervention. The intervention is being delivered by research personnel at the University of Washington associated with the HEALTH-HIV study (NCT04550676). Data for this study will only be collected at the University of Washington site of the HEALTH-HIV study.
NCT00071786
This study will examine how depression, anxiety, and migraine run in families. It will help in defining the risk factors for physical, mental, and health problems-as well as define ways that those problems may be prevented and treated. A broad range of ages among family members will be included to evaluate the patterns of how these disorders are expressed throughout people's lives. Children of all ages will be included, and those ages 8 to 17 will be interviewed directly. Assessments will be collected through criteria of the Diagnostic and Statistical Manual of Mental Disorders IV as well as the spectrum, or range, of mood disorders and co-existing conditions. A member of the study team will visit the participants at home or will do an interview by telephone. Participation will take approximately 3 to 4 hours. Children will complete questionnaires given by the research team as well as questionnaires that they will do by themselves. The questions will pertain to the children's health, including physical and mental health and medical history, social relationships, problems, skills, and ways of dealing with important or stressful issues in their lives. These questionnaires will take up to 1 hour to complete. Health history gathered from adult participants will pertain to height, weight, exercise, and general function. Women will be asked about the use of oral contraceptives, estrogen, and progesterone. In addition, there will be questionnaires on personality and temperamental traits, that is, behavior and impulsiveness. Questions will also involve social intuition, family and other environmental factors, general functioning, and basic demographics such as ethnicity, race, socioeconomic status, marital status, education level, and employment history. Families enrolled in this phase of the research will be invited to participate in the next phase. There would be follow-up to evaluate the development of mood disorders, subtypes, and syndromes across the lifespan.
NCT07082218
Following adolescent concussion, poor sleep health is common and relates to the development of persisting post-concussion symptoms, and uninjured adolescents (independent of concussion) also commonly experience sleep insufficiency. Given the sparse guidance that exists for clinicians to provide evidence-based sleep health recommendations for adolescents with a concussion, the primary objectives of this prospective randomized clinical trial of adolescents with a recent concussion are to discover if a multidimensional and prescriptive sleep health intervention leads to: 1) faster symptom resolution time, better sleep quality, or longer sleep duration; and 2) improved sleep habits, mental health, or academic engagement, relative to standard-of-care post-concussion sleep health guidance. Findings from this research will provide the basis for more precise sleep health recommendations for adolescents who experience a concussion.
NCT05956964
The goal of this trial is to learn about how restricted sleep and not bearing weight on the leg affects muscle strength and posture control. Participants will walk exclusively on one leg, sleep at differing intervals, and complete posture tests, muscle strength tests, and muscle imaging. Researchers will compare adequate sleep and restricted sleep to see if muscle strength and posture are affected.
NCT07406620
This observational study is being undertaken as a part of a Master of Research (MRes) in Clinical Research programme. Its goal is to learn about how continuous positive airway pressure (CPAP) therapy changes the complexity of body signals in adults with obstructive sleep apnoea (OSA). The main question it aims to answer is: \- How does the complexity of physiological signals (specifically oxygen saturation, heart rate, and heart rate variability) change in adults with OSA from before to after three and six months of CPAP treatment? It will use data from individuals who took part in an earlier trial, called 3DPiPPIn, which tested the use of 3D-printed, customised masks CPAP masks through sleep studies.
NCT07225686
This Phase 3 clinical trial is designed to evaluate the efficacy and safety of maridebart cafraglutide compared to placebo over a 52-week period in adults with obstructive sleep apnea (OSA) who are receiving positive airway pressure (PAP) therapy and are living with overweight or obesity.
NCT01115686
The initial hypothesis is that branched-chain aminoacids (BCAA) administration could be beneficial to patients suffering from sleep apnea syndrome (SAS), the aim of the present work is to verify this hypothesis. The literature data demonstrate that a BCAA complementation improves the physical performances, protects lean mass and increases VO2 max during training. We demonstrated earlier that this complementation can cure at less partly the hypoxemia of chronic obstructive pulmonary patients by a stimulation of respiratory centres.
NCT07047092
Chronic obstructive pulmonary disease (COPD) is a major public health problem with 212.3 million prevalent cases of COPD worldwide and 3.3 million deaths related to COPD in 2019. Obstructive sleep apnoea (OSA) is the most common sleep disordered breathing. It is estimated that almost 1 billion adults have OSA worldwide. Given the increasing prevalence of obesity, co-morbid OSA is frequently seen in patients with COPD. Co-morbid OSA has been shown to increase mortality, to reduce quality of life and to favour acute exacerbation of COPD. For those admitted for a life-threatening exacerbation of COPD requiring an intensive care admission for acute hypercapnic failure, they are more likely to get readmitted. For those admitted for an acute exacerbation in any ward, they are more likely to be re-admitted for another exacerbation within 180-days if their OSA is not treated. Unfortunately, data regarding the best management of OSA in patients with co-morbid COPD are lacking as they were often excluded from clinical trials involving patients with COPD. Therefore, CPAP or NIV are administered without scientific evidence establishing which treatment is the most appropriate.
NCT07631494
Delirium affects up to 83% of mechanically ventilated patients in the Intensive Care Unit (ICU), often leading to longer hospital stays and long-term memory or cognitive problems. While standard care protocols (such as the ABCDEF bundle) exist, they are often difficult to implement fully due to their complexity and the heavy workload on nursing staff. To address these challenges, this study introduces a 'Precision Nursing' approach by integrating Artificial Intelligence (AI) and Virtual Reality (VR). We will implement an AI-driven system to assist nurses in making personalized care decisions more efficiently. Additionally, interactive VR technology will be used to stimulate patients' cognitive function and encourage early mobility. Our goal is to reduce the clinical burden on healthcare providers while significantly improving recovery outcomes for ICU patients.
NCT06949644
The goal of this observational study is to characterize the pupil light response in patients with delayed sleep-wake phase disorder. A subset of participants will take part in a clinical trial to determine if increasing serotonin can alter the circadian response to light. The main questions it aims to answer is: Are there differences in the light response in patients with delayed sleep-wake phase disorder? Does citalopram increase melatonin suppression in patients with delayed sleep-wake phase disorder? Participants will complete activity and melatonin testing at home to determine their circadian timing. This will be followed by an eye test looking at the pupil response to different light stimuli. A subset of participants will complete two inpatient admissions where melatonin levels will be sampled and they will be exposed to a bright light. During one round of testing they will receive a placebo and in the other round of testing they will take a single dose of citalopram, a selective serotonin reuptake inhibitor.
NCT06283017
This proof-of-concept study is being performed to evaluate whether the hypoglossal nerve can be stimulated using a small series of electrodes placed surgically via a percutaneous approach. Minimally invasive off the shelf medical devices will be used and observation of the characteristic physiological responses to stimulation of the HGN, will be assessed.
NCT07580170
The aim is to investigate whether the tissue-preserving tonsil surgery technique is as effective as complete tonsil removal in the treatment of obstructive sleep apnea. The primary outcome measure is the change in the apnea-hypopnea index (AHI) before surgery and at 4-6, 24, and 60 months after surgery.
NCT07610343
Patients with cognitive decline are frequently comorbid with sleep disorders which may in turn aggravate cognitive decline. Sedative dose dexmedetomidine improved sleep quality but incresed bradycardia and hypotension; low dose dexmedetomidine produce less side effects, but the sleep promoting effects are relatively weak. Low dose esketamine also has sleep-promoting effects but may produce neuropsychiatric side effects. Both dexmedetomidine and esketamine are approved for intranasal administration. We suppose that intranasal administration of dexmedetomidine-esketamine combination may improve sleep quality and therefore cognitive function in older ptients with Alzheimer's disease cognitive impairment and sleep disorders.

This study is a multi-center, double-blind, placebo-controlled, randomized Phase 3 trial to assess the safety and efficacy of AXS-12 in narcoleptic subjects with cataplexy and excessive daytime sleepiness (EDS).
NCT07160868
The OSADA (Obstructive Sleep Apnoea in Difficult Asthma) trial is an open-label, randomized control trial investigating the impact of diagnosing and treating obstructive sleep apnoea (OSA) on a asthma control in patients with difficult-to-control asthma. Participants will undergo home-based sleep studies to assess for OSA and are then allocated to one of three arms: 1) Patients with OSA treated with CPAP (intervention group), 2) Patients with OSA not treated for OSA (control group) and 3) Patients without OSA (reference group). The primary objective is to evaluate whether treating OSA improves asthma control, symptom burden, and quality of life compared to untreated OSA and to patients without OSA. Secondary outcomes include exacerbation rates, sleep quality, and healthcare utilization. This trial aims to clarify the contribution of OSA to poor asthma control and the potential benefits of integrated sleep and respiratory care in this complex population.
NCT07434921
The goal of this randomized controlled educational study is to learn whether a structured, theory-based program can help reduce drowsy driving among college students (18 years and older) in Nevada. Drowsy driving means driving when you are very sleepy, tired, or struggling to stay alert. It is a serious safety problem because it can slow reaction time, reduce attention, and increase the risk of crashes, injuries, and even deaths. Many college students have irregular sleep schedules due to classes, jobs, late-night studying, and social activities, which can increase tiredness and increase the likelihood of drowsy driving. Research question 1. Is there a statistically and practically significant difference in the mean score of drowsy driving behavior in the experimental group (Multi-Theory Model (MTM)-based intervention, Stay Awake, Stay Alive©) and the comparison group (standard AAA (American Automobile Association)program-based intervention) from pre-intervention to post-intervention to two-week follow-up 2. Is there a statistically and practically significant difference in the mean score (pre-intervention to post-intervention to two-week follow-up) for the intent to initiate reducing drowsy driving between the experimental (MTM-based intervention, Stay Awake, Stay Alive©) and comparison (standard AAA program-based intervention) groups? 3. Is there a statistically and practically significant difference in the mean score (pre-intervention to post-intervention to two-week follow-up) for the intent to sustain the reduction of drowsy driving between the experimental (MTM-based intervention, Stay Awake, Stay Alive©) and comparison (standard AAA program-based intervention) groups? Researchers will compare two groups to see which approach leads to greater improvement: Group 1: MTM-based "Stay Awake, Stay Alive" program (interactive weekly sessions designed using behavior change theory). Group 2: Standard drowsy driving education program, AAA (American Automobile Association) based education. By comparing these groups, researchers can see whether the MTM-based program provides added benefit beyond standard education alone. Both groups receive the same overall time and attention, so differences in results can be linked more clearly to the program's strategies rather than to simply receiving education. Participants will: * Complete a short screening to confirm eligibility (for example, being 18+ and having recent experiences of drowsy driving) * Provide informed consent before any study activities begin * Be randomly assigned to one of the two programs * Attend four weekly sessions (about 75 minutes each) over 4 weeks, with a short break and refreshments during sessions * Complete surveys at three time points: Baseline (before the program begins), Post-intervention (after week 4), and Follow-up (after two weeks) * Answer questions about their drowsy driving behavior and related influences, such as fatigue triggers, barriers to sleep, confidence to avoid driving when sleepy, and supports that make safe choices easier. The study will measure changes in drowsy driving behavior and in MTM-related factors that may explain why these changes occur. For example, the MTM-based program helps students think about the benefits of avoiding drowsy driving (and the risks of continuing it), build behavioral confidence to choose safer options, and identify practical environmental supports (such as a safe place to rest, asking a friend for a ride, using ride-share or public transportation, or adjusting trip timing). It also supports emotional transformation (turning concern into motivation), practice for change (setting goals and tracking progress), and building a supportive social environment (friends and family encouraging safer choices). During the sessions, participants may learn and practice real-world skills such as recognizing early warning signs of sleepiness (heavy eyelids, frequent yawning, drifting lanes, missing exits), using short rest breaks and safe "pull-over" plans, managing schedules to reduce late-night driving, and creating a personal action plan for high-risk situations (after work shifts, long study nights, or long-distance travel). The follow-up survey helps researchers see whether any improvements continue beyond the end of the 4-week program. At the end of the study, results will help colleges, public health professionals, and road safety programs understand what types of education are most effective for preventing drowsy driving in young adults. If the MTM-based program is effective, it could be adapted and used more widely to improve student safety and reduce injuries related to drowsy driving. Participants who complete the final follow-up survey will receive an incentive.
NCT07152262
This study aims to investigate the effects of different phases of the menstrual cycle on gait spatiotemporal characteristics, pelvic kinematics, and sleep quality in healthy women aged 18-35 years with regular menstrual cycles. Participants will be assessed in three phases of the cycle: early follicular (days 1-3), ovulation (days 7-9, confirmed by ovulation test), and luteal (days 20-23). Gait parameters and pelvic kinematics will be evaluated using the BTS-G walk sensor system, while sleep quality will be assessed with the Pittsburgh Sleep Quality Index (PSQI). The study seeks to determine whether physiological and hormonal changes during menstrual phases lead to measurable differences in gait, pelvic motion, and sleep quality.
