NCT ID: NCT04896671 Completed - Clinical trials for Broad Autism Phenotype

Physical Exercise Training to Enhance Executive and Social Functions

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

Background and study aims: Executive functions (EF) and social functions are important for self-regulation, problem solving, and attaining future goals yet they are impaired in Autism Spectrum Disorder (ASD). Physical exercise (PE) is found to enhance these central cognitive and social impairments in ASD. While limited research has begun to target these impairments in clinical samples, the presence of sub-clinical traits of ASD (refer to as broad autism phenotype (BAP)) in the general population is more common than the 1% prevalence of ASD. Therefore, it is crucial to study these impairments in the sub-clinical individuals. This study aims to investigate the effectiveness of PE in enhancing the EF and social functions in the BAP adolescents. Method: Participants will be recruited from the local community and they should be between the age of 7-20 years without any psychiatric disorders. Expected results: PE is predicted to be effective in reducing the EF and social impairments in these adolescents. Implications: These findings can inform us with the knowledge to design a community-based PE training targeting EF problems in these adolescents with BAP in the local context. Ultimately, this training can be incorporated to the curriculum of the primary and secondary schools targeting BAP and associated impairments in adolescents.

NCT ID: NCT04891796 Completed - Clinical trials for Survey on Tobacco Control

Tobacco Control Policy-related Survey 2020

Start date: March 12, 2021
Phase:
Study type: Observational

Aim: to collect further information on issues related to tobacco control which should be addressed and advocated in further tobacco control measures in Hong Kong The objectives of this policy-related survey by landline and mobile telephone are as follows: 1. to update information on prevalence of conventional cigarettes, e-cigarettes, heat-not-burn tobacco products and waterpipe tobaccos ; 2. to investigate the effects of new pictorial health warning policy in the public; 3. to investigate the level of public support on current and future tobacco control measures and taxation; 4. to address the timely impacts of smoke-free policies, public support for further tobacco control measures and assist COSH in shaping policy direction for government; Current study is a cross-sectional retrospective landline and mobile telephone survey based on questionnaires. The target sample size is planned to be 5,100 Hong Kong residents, including 1,700 current, ex and never smokers respectively. All three smoking status are to be evenly sampled by landline and mobile telephone. All data will be collected using a Computer Assisted Telephone Interview (CATI) system, which allows real-time data capture and consolidation. All interviews shall be conducted anonymously except for those who are willing to participate subsequent studies pictorial warning opinion. Analysis of survey data will aim to identify current opinion on tobacco control policies and implications for future policies. All eligible subjects who complete the telephone survey will be included in the analysis. Comparison with past trends conducted by previous landline and mobile phone surveys and, where possible, extrapolation of future trends will be explored. Weightings will be applied to adjust for the sex and age of Hong Kong population, and to handle the over-sampling issues of ex- and current smokers. The data analysis will be conducted by experienced statisticians in the applicants' team.

NCT ID: NCT04890223 Completed - Smoking Cessation Clinical Trials

Efficacy of Brief MI Delivered Via Mobile Instant Messaging to Help Unmotivated Smokers With Chronic Diseases to Quit

Start date: June 1, 2021
Phase: N/A
Study type: Interventional

This study aims to examine the efficacy of brief MI delivered by mobile instant messaging tools in promoting smoking cessation among unmotivated smokers with chronic diseases. Participants in the intervention group will receive a brief MI intervention while the control group will receive a placebo intervention.

Improving Sleep With the Far-infrared Emitting Pyjamas

Start date: July 15, 2021
Phase: N/A
Study type: Interventional

The aim of this study is to explore the effects of a far-infrared emitting pyjamas on improving sleep in adults with poor sleep.

NCT ID: NCT04884672 Completed - Myopia Clinical Trials

PMCF Study on SMILE Treatment of Myopia With and Without Astigmatism

Start date: July 9, 2021
Phase:
Study type: Observational

The primary objective of this PMCF investigation is to systematically collect safety and effectiveness data with the VISUMAX 800 laser in clinical daily routine SMILE use for the purpose of post market surveillance.

NCT ID: NCT04878198 Completed - Clinical trials for Autism Spectrum Disorder

Treatment of Sleep Disturbance in Children With ASD

Start date: December 2, 2022
Phase: N/A
Study type: Interventional

This RCT study aims to compare effectiveness physical exercise and melatonin supplement on treating sleep disturbance in children with ASD. A four-arm randomized controlled trial with equal allocation ratio to the three intervention groups (i.e., jogging; melatonin supplement, combine jogging and melatonin supplement) and one placebo-control group will be conducted . Actigraph device and sleep log will be used for sleep assessment. 6-sulfoxymelatonin from 24-h and first morning urinary samples. The investigators will monitor the changes of four sleep parameters (sleep onset latency, sleep efficiency, wake after sleep onset and total sleep duration) and the 24-h and first morning melatonin level throughout the whole study.

NCT ID: NCT04870996 Completed - Schizophrenia Clinical Trials

RCT of tDCS Combined With Cognitive Training in Schizophrenia

Start date: August 23, 2019
Phase: N/A
Study type: Interventional

Given the superior effects of CT augmented tDCS in healthy subjects, the aim of the current study was to examine whether the effect of CT on cognition can be enhanced with concurrent anodal tDCS in schizophrenia patients. A double-blinded randomised controlled trial design was utilised and cognitive performances were examined at baseline (T0), immediately after the intervention (T1) and one month post-intervention (T2). It was hypothesized that concurrent CT with tDCS would result in greater and more sustainable cognitive improvement than CT alone because of increased susceptibility to neuroplasticity changes of the underlying activated network (Bikson et al., 2013; Orlov, O'Daly, et al., 2017). The effects of concurrent CT with tDCS were also assessed using blinded assessments of psychotic, negative symptoms, affective symptoms, psychosocial functioning, subjective quality of life (QOL) and tolerability in the two groups.

NCT ID: NCT04868331 Completed - Clinical trials for Adolescent Idiopathic Scoliosis

Cardiovascular Responses in Adolescent Idiopathic Scoliosis Girls

Start date: May 18, 2021
Phase: N/A
Study type: Interventional

The aims of this pilot study are to determine the metabolic demand and exercise intensity level of E-Fit exercise intervention by evaluating the cardiovascular responses in AIS girls and whether the cardiovascular responses for AIS girls performing E-Fit will behave in the same way as compared to healthy controls. We hypothesise that 1) the metabolic demand and exercise intensity of E-Fit exercise intervention is equivalent to moderate-to-vigorous level; and 2) AIS girls have different cardiovascular responses as compared to healthy controls

This is a prospective study of IOP in Intravitreal injections to evaluate: 1. IOP effect of intravitreal injection 2. IOP response to prophylactic beta blocker or Prostaglandin vs control (Hypromellose) over multiple time periods 3. IOP response in correlation to number of injections, IOL, type of anti VEGF, co morbidities

Thromboxane B2 and Platelet Function Testing as Measures of Aspirin Resistance in Hong Kong Chinese Patients

Start date: April 2, 2015
Phase:
Study type: Observational

The hypotheses of the study are that the diagnostic accuracy of Multiplate® device for diagnosis of aspirin resistance is comparable to the serum TXB2 assay and that certain genetic polymorphisms and phenotypic factors significantly influence the antiplatelet effect of aspirin and contribute to aspirin resistance observed in this study.
