Active clinical trials for "Sleep Wake Disorders"

This study will inform the field about underlying mechanisms associated with infant sleep problems and will deepen the understanding of the intervention process. The study will provide detailed information on the intervention process itself and will explore how behavioral sleep interventions affect broader infant outcome.

The proposed research project is aimed at further characterization of sleep problems and evaluation of their impact in children and adults with TSC, excluding epilepsy as contributing factor. Questionnaire-based studies have shown that sleep problems occur in up to half of the children and a third of adults with tuberous sclerosis complex (TSC). However, there is only limited information on the nature of sleep problems and their impact on patients with TSC and their families.

There is a well-documented but poorly understood relationship between headache disorders (e.g. migraine, cluster headaches, awakening headaches, etc.) and sleep disorders. One hypothesis includes an underlying disorder known as obstructive sleep apnea (OSA) with low overnight oxygen saturations and possibly elevated carbon dioxide levels which result in awakening headache. Bruxism, or grinding of the teeth, has also been anecdotally associated with headache. The converse of these arguments is that the patient may have a primary headache disorder, for example migraine, leading to disordered sleep patterns or insomnia. The true relationship between the two, as alluded above, is unknown. The actual prevalence of the two disorders occurring simultaneously is not known. There have been several small, retrospective studies which have attempted to evaluate this relationship. One of these studies evaluated those patients diagnosed with OSA who were given the standard of care therapy - continuous positive airway pressure (CPAP) - and found that headaches among these patients were improved after using CPAP. Again, this was a small, retrospective study. We propose a study whereby patients who are referred for polysomnography (PSG, or "sleep study") are consented, then surveyed on the presence or absence of headache. A brief questionnaire is followed up with a more detailed questionnaire to characterize whether this headache that the patient has is truly a headache disorder. Following the survey and PSG, the patient's sleep study parameters are evaluated to see whether there are certain correlations between what has been recorded and the particular headache disorder present. Lastly, if the patient was diagnosed with OSA and fitted with a CPAP device, the patient will be queried several weeks later to evaluate whether there was improvement or cessation of the headache disorder.

It is recommended by the American College of Obstetricians and Gynecologists' Committee on Obstetric Practice that all obstetricians screen each women for postpartum depression and anxiety with a validated instrument. Although much effort is made, the contributing factors still lack in the literature due to its multi-factorial nature and complexity. In addition, the effects of prenatal education classes remain understudied. Therefore, this study aims to demonstrate the prevalence, characteristics and contributing factors of the postpartum depression. In addition, the change in prevalence and characteristics of the postpartum depression among women who had prenatal classes and not will also be assessed.

Comparison of the prevalence of obstructive sleep apnea (OSA), measured by polysomnography in normal weight patients with central obesity by body mass index (BMI) and waist hip ratio (WHR), with normal weight patients without central obesity by BMI and WHR. Evaluation of arterial stiffness and vascular age in normal weight patients with central obesity and in normal weight patients without central obesity. Determination of the exercise response characteristics in OSA patients.

The aim of this study is to observe the sleep and activity patterns of pre-menopausal breast cancer patients taking tamoxifen using a wrist-worn internet of things device and questionnaires.

The development of sleep wake cycles is indicative of child's neurocognitive functions. Caffeine therapy is commonly used in neonatal intensive care units for treatment of apnea of prematurity (AOP), to reduce mechanical ventilation, and improve the success of extubation. In addition, it is suggested to be associated with positive long-term outcomes on pulmonary function and neurodevelopment. However, it is still not clear how caffeine therapy affects the sleep architecture and neurodevelopment of preterm infants. Furthermore, optimal dosing and timing of caffeine therapy is controversial. We aimed to evaluate the effects of caffeine therapy on sleep architecture and neurodevelopment in preterm infants during the first year of life. A prospective observational case-control study will be conducted. Forty preterm infants aged between 28 to 34 gestational weeks admitted to the Marmara University Neonatal Intensive Care Unit (NICU) from May 2020 to May 2021 will be included. Infants with neonatal risk factors for poor neurodevelopmental outcomes will be excluded. Duration, timing and cumulative dosage of caffeine therapy will be calculated. Follow up outcome for neurodevelopment and sleep architecture of preterm infants who received caffeine therapy will be compared with those who did not receive caffeine therapy. Sleep and activity behavior recorded by actigraphy, sleep diary and polysomnography at 6, and 12 months corrected age will be compared to noncaffeine group. Neurodevelopment will be assessed by neurological examination defined by Hammersmith, Ages and Stages Questionnaire (ASQ-2), and Bayley Scales of Infant and Toddler Development.

Sleep disorders are common in patients who have chronic kidney disease (CKD). Insomnia is reported in up to 50% of patients treated with hemodialysis compared to 12% of a control population. Restless leg syndrome (RLS) and periodic limb movement disorder (PLM) have been described in 30 to 70% of patients with end stage kidney disease (ESKD). Patients with CKD have also been reported to have a very high prevalence of sleep apnoea disorder. Conventional hemodialysis and peritoneal dialysis do not appear to improve sleep disorders in patients with CKD. There is emerging evidence that nocturnal HD can lead to improvements in sleep quality. Transplantation is thought to improve sleep-related disorders in some but not all patients. Project Aims The aims of this project were three-fold: To perform detailed assessment of sleep quality in a cohort of Irish patients with ESRD To assess the feasability and tolerability of unattended home PSG and wrist actigraphy as diagnostic tools in this cohort To assess the impact of a change in RRT modality on sleep quality in Irish patients with ESRD

RATIONALE: Studying samples of blood in the laboratory from patients with breast cancer may help doctors learn more about changes that occur in DNA and identify biomarkers related to fatigue. PURPOSE: This research study is studying biomarkers associated with fatigue in patients with early-stage breast cancer treated with metformin or placebo on NCIC-CTG-MA.32.

ADHD is often associated with sleep difficulties. Attention-deficit/hyperactivity disorder (ADHD) is the most common problem presented to children mental health services. The disorder affects approximately 5 % of school-age children. The core symptoms of this disorder include varying degrees of inattention, impulsiveness and restlessness. In addition to the core symptoms, ADHD is associated with other problems (e.g. academic underachievement, poor social relations and sleep disturbances). Despite clinical observations of sleep problems in children with ADHD, there is little empirical research on this topic. The prevalence, type of sleep problems, and significance of these sleep disturbances in children with ADHD remain undocumented. The objective is to determine the relationship of sleep problems to attention deficit/hyperactive disorder, comorbid disorders, and the effect of stimulant treatment.
