NCT ID: NCT06260020 Not yet recruiting - Clinical trials for Autism Spectrum Disorder

Development and Validation of a Comprehensive Module for Management of Sleep Disorders in ASD Children

Start date: February 20, 2024
Phase: N/A
Study type: Interventional

Sleep disorder in autism children is common and it affects the physical, behavior and mental health. There is lack of comprehensive management program/module to treat the sleep disorders in children with ASD. Limited studies evaluating the utility of actigraphy to diagnose sleep disorders in ASD and its validation with PSG are present. Rationale of this study is to develop the comprehensive module and validate it for children with autism spectrum disorders, so as to improve the behavioral outcomes as well. This study also helps to utilize actigraphy as a modality to diagnose sleep disorders in children with autism spectrum disorder as performing PSG in these children is cumbersome and difficult as ASD children tend to have sensory abnormalities.

NCT ID: NCT06199596 Completed - Chronic Insomnia Clinical Trials

Alpha-s1 Casein Hydrolysate on Sleep

Start date: May 1, 2019
Phase: N/A
Study type: Interventional

This study investigates the impact of Aalpha-s1 casein hydrolysate (ACH; Lactium®) on sleep quality in individuals with chronic insomnia, employing both subjective sleep profiles and objective polysomnography (PSG) recordings.

NCT ID: NCT04417556 Completed - Sleep Clinical Trials

Validation of Various Sleep Assessment Tools in SICU

Start date: July 1, 2020
Phase: N/A
Study type: Interventional

Sleep deprivation is common in critical patients and it can cause impair consolidation of memory, cognitive function, metabolic function, immune, neurological and respiratory system as well as worsen the quality of life after discharge. It has been demonstrated that reducing sleep disturbance could attenuate the development of delirium in ICU patients. However, sleep evaluation is only personal perception. There are various methods for sleep monitoring, in which the most commonly mentioned methods include polysomnography, actigraphy, and the Richards-Campbell Sleep Questionnaire (RCSQ). The aims of this study is to validate the accuracy of the Thai-version RCSQ and actigraphy for sleep measurement compared to polysomnography, which is considered as the gold-standard in Thai critically ill patients admitted to surgical intensive care unit.

NCT ID: NCT04340310 Recruiting - Sleep Apnea Clinical Trials

Home Respiratory Polygraphy in Childhood Sleep Apnea-Hypopnea Syndrome (CHILDSLEEP).

CHILDSLEEP
Start date: February 6, 2019
Phase:
Study type: Observational [Patient Registry]

The aims of the study is to assess the diagnostic utility of home respiratory polygraphy (HRP) complemented with polysomnography (PSG) in childhood Obstructive Sleep Apnea-Hypopnea Syndrome (OSAS), as well as its usefulness in the therapeutic decisions. Methods: Children referred with suspected OSAS will be evaluated during one year performing home respiratory polygraphy in all cases. PSG will be chosen in patients with concomitant pathology or according to medical criteria, or complemented with HRP in doubtful cases. Clinical and anthropometric data, severity, technical quality and treatment will be obtained. Patients will be divided in two groups (HRP vs PSG) and compared, and the accuracy from HRP to establish a therapeutic decision it wil calculated. The investigator's hypothesis is that PSG should be recommended only for complex or doubtful cases.

The TOH sleep database was created as a part of the project: "Validation of provincial health administrative data algorithms to identify patients with obstructive sleep apnea (OSA): Feasibility project". Protocol ID: 20170591-01H (AMENDMENT APPROVED on December 19, 2018) to be used for future clinical, research, educational and quality improvement purposes.

NCT ID: NCT03782844 Completed - Clinical trials for Sleep Apnea, Obstructive

Efficacy of Simple Continuous Positive Airway Pressure on Patients With Obstructive Sleep Apnea

Start date: January 2, 2019
Phase: N/A
Study type: Interventional

Obstructive sleep apnea (OSA) is a common and frequently-occurring disease. The incidence of OSA is more than 4% in general population, and as high as 20% - 40% in the elderly. At present, CPAP machines commonly used for OSA treatment includes traditional pressure fixed single-level CPAP machine and automatic pressure regulation CPAP machine. Studies have shown that the CPAP treatment pressure of OSA patients is normally below 11 cmH2O. Since the condition of OSA patients and the required CPAP treatment pressure may change over time, a CPAP machine with automatic pressure regulation function may theoretically better meet the needs of treatment. However, a recent large-scale clinical study with an average follow-up of four years showed that there was little need to change CPAP treatment pressure after titration. Although different types of CPAP have different functions, the basic principle is to keep the upper airway open and unobstructed to eliminate sleep apnea and hypopnea by continuously applying positive pressure to the upper respiratory tract through an air pump. A complex CPAP machine with functions such as pressure regulation, boost delay, end-expiratory pressure release will cost more than a single-function CPAP machine. Some patients from poor areas, even with severe OSA, may give up treatment when they can not afford CPAP machines that have not yet been included in national health insurance in China. In view of the current economic level in China, it is urgent to find an inexpensive and effective CPAP machine for the treatment of OSA and related complications. Recently, Guangzhou Yinghui Medical Technology Co., Ltd.and State Key Laboratory of Respiratory Disease have developed a new simple CPAP machine. The CPAP treatment pressure is fixed at the factory to 6 cm H2O (SKL), 8 cm H2O (SKM) and 10 cm H2O (SKH). Compared to traditional CPAP machine, only a power switch button is attached on the body, and the additional adjustment devices including display screen are removed, which not only reduces the cost of the CPAP machine, but also facilitates the operation of patients.

NCT ID: NCT03477812 Recruiting - Nocturnal Enuresis Clinical Trials

Sleep and Nocturnal Enuresis: Ambulatory Polysomnographic Study

Start date: January 22, 2018
Phase:

Full ambulatory polysomnography at home performed two nights in 30 healthy children and one night in 30 children with mono-symptomatic nocturnal enuresis (15 with polyuria and 15 without polyuria). The children will be aged 7-14 years of age. The sleep will be evaluated on sleep quality, number of periodic limb movements per hour, blood pressure and pulse, beat to beat variation by electrocardiography during sleep, respiration during sleep, nocturnal urine production, and enuresis episodes.

NCT ID: NCT03445962 Completed - Clinical trials for Sleep Apnea, Obstructive

19/5000 (SYNAPSOT21) Predictive Factors of Sleep Apnea Syndrome in Down Syndrome

SYNAPSOT21
Start date: November 15, 2017
Phase:
Study type: Observational

The obstructive sleep apnea syndrome (OSAS) is frequently reported in subjects with trisomy 21. The consequences of this syndrome are expressed in various disorders such as cognitive and cardiovascular alterations. It is also reported a premature exhaustion with the achievement of various professional or recreational activities, as well as an increase in the frequency of daytime sleepiness. In trisomy 21, there are factors that are systematically associated with obstructive apnea. The identification of these factors would make it possible to diagnose OSAS earlier, under-diagnosed in the population with trisomy 21 even though these OSAS are associated with increased cardiovascular risks. The aim of this study is to identify the predictive factors associated with sleep apnea in the trisomy population in order to propose early detection. OSAS treatment in a young adult with Down syndrome could reduce physical fatigue apparition during various activities, reduce daytime sleepiness, and have a positive impact on physical fitness, and therefore more broadly on health.

NCT ID: NCT02549027 Completed - Polysomnography Clinical Trials

A Study to Evaluate the Effects of Single Doses of MK-1064 and MK-6096 on Polysomnography (PSG) (MK-1064-003)

Start date: November 6, 2009
Phase: Phase 1
Study type: Interventional

The purpose of this randomized, double-blind, placebo-controlled, 5-period crossover study is to assess the effect of single oral doses of MK-1064 on latency to persistent sleep (LPS) as measured by polysomnography (PSG) in healthy young male participants, and to evaluate the safety and tolerability of single oral doses of MK-1064 and MK-6096 in healthy young male participants. The primary efficacy hypothesis is that at least one dose of MK-1064 is superior to placebo in decreasing LPS in healthy male participants as assessed by PSG.
