Start date: August 4, 2018
Phase: N/A
Study type: Interventional

NCT ID: NCT03880344 Not yet recruiting - Knee Osteoarthritis Clinical Trials

Investigating the Effectiveness of Vibration Therapy on Sarcopenia in Osteoarthritis Knee Patients

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

Osteoarthritis (OA) is one of the commonest chronic degenerative conditions affecting our aging population. It limits joint movement and causing disability in elderlies due to discordant symptoms such as pain and stiffness. The prevalence of radiologic knee osteoarthritis increases in proportion to age, reaching an astounding 64.1% for patients whom are over 60 years of age. In addition the prevalence of symptomatic knee OA has been shown to be around 10% in people who are 60 years and older.

NCT ID: NCT03880292 Not yet recruiting - Spinal Deformity Clinical Trials

Spinal Deformity Intraoperative Monitoring.

Start date: May 15, 2019
Phase: N/A
Study type: Interventional

A multicenter, international prospectively collected patient cohort undergoing high-risk spinal cord level surgery or spinal osteotomy procedures will be enrolled to establish the incidence of intraoperative alerts in high-risk spinal cord cases, and explore factors associated with mitigating injury. Baseline, intraoperative, and postoperative characteristics, including demographics, radiological features, lower extremity motor score (LEMS), procedure, anesthetic agents used, and baseline blood pressure will be recorded for either adult patients or pediatric patients.

NCT ID: NCT03879902 Recruiting - Fall Patients Clinical Trials

The Characteristics of Falls and Its Potential Predictors

Start date: July 20, 2017
Phase:
Study type: Observational

A prospective study to examine the fall characteristics among elderly faller in Hong Kong and the potential predictors of falls incidence.

NCT ID: NCT03879889 Recruiting - Smoking, Tobacco Clinical Trials

Smoking Reduction Intervention for Smoking Parents of Paediatric Patients in Hong Kong

Start date: February 1, 2017
Phase: Phase 4
Study type: Interventional

A randomized controlled trial to evaluate the effectiveness of smoking reduction interventions for smoking parents in paediatric hospital setting in Hong Kong.

NCT ID: NCT03879343 Recruiting - Clinical trials for Attention Deficit Disorder With Hyperactivity

The Prevalence and Predictors of Gastrointestinal Symptoms in Children With Attention Deficit / Hyperactivity Disorder

Start date: July 1, 2018
Phase:
Study type: Observational

This study is to examine the gut problems in children with attention deficit hyperactivity disorders (ADHD) and is conducted by the Department of Psychiatry of Alice Ho Miu Ling Nethersole Hospital. Children with ADHD who attend our department will be recruited with their parents/guardians' consent. Only the primary caregiver will be invited for an interview to assess the recruited children's gut problems, autistic features, emotional problems, diet pattern and medical history. The data will be compared with normal children who are recruited as control in local primary schools. The aim of this study is to know whether children with ADHD have higher chance of gut problems, and to assess other factors associated with the linkage.

NCT ID: NCT03875872 Active, not recruiting - Acute Pain Clinical Trials

Comparison of Postoperative Outcomes Between Surgeries Anaesthetized With Propofol and Inhalational Anaesthetics

Start date: February 11, 2019
Phase:
Study type: Observational

Propofol used as anaesthesia in surgery had shown small postoperative analgesic benefits over inhalational anaesthetics in some meta-analyses. It was also associated with reduced risk of postoperative nausea and vomiting. Small sample of studies together with high heterogeneity prevented some meta-analyses to confirm propofol's effect for postoperative morphine consumption and other outcomes. Acute Pain Service data bank can provide an alternative way of evaluating postoperative outcomes of propofol anaesthetics through supplying a very large sample size in a more homogeneous setting. Retrospective study comparing propofol and inhalational anaesthetics on postoperative pain matched on patients' demographic and clinical data had been done for liver surgery. Propofol's benefits for postoperative pain and morphine consumption was confirmed but not for adverse effects. This study plans to analyze the postoperative outcome data from an Acute Pain Service data bank in years 2015-17 to compare the anaesthetics of propofol and inhalational anaesthetics. Comprehensive regression adjustment for confounders are performed using all available patients' demographic, clinical and anaesthetic data. All major surgery types are included. Results will provide postoperative outcome differences between propofol and inhalational anaesthetics for all surgeries and for specific type of surgeries. The large sample bank will provide higher probability for detecting outcome difference between the anaesthetics for all the major surgical types.

NCT ID: NCT03875677 Recruiting - Stroke Clinical Trials

High-definition Transcranial Direct Current Stimulation for Facilitating Hand Function Recovery After Stroke

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

Transcranial direct current stimulation (tDCS) had recently been shown having feasibility in modulating cortical excitability transiently during motor training in a noninvasive way. The findings support that tDCS and motor practice can positively promote post-stroke motor learning to improve upper-limb motor recovery after stroke. A randomized controlled trial will be conducted with three groups: HD-tDCS, conventional tDCS and sham HD-tDCS. A 10-session training will be provided to evaluate the effectiveness of transient modulation of cortical excitability through tDCS with clinical assessment scores.

NCT ID: NCT03875625 Recruiting - Diabetes Mellitus Clinical Trials

Change of Adipose Tissues and Triglyceride After Bariatric Surgery or Life-style Intervention

Start date: March 12, 2019
Phase: N/A
Study type: Interventional

The study is aimed - To quantify the change of adipose tissues, triglyceride in liver and pancreas and cholesterol after lifestyle intervention or bariatric surgery. - To test the hypothesis that Brown fat is an independent biomarker for the development of Non Alcoholic Fat Liver Disease (NAFLD) - To study the association among Brown fat, NAFLD and obesity.

NCT ID: NCT03870906 Recruiting - Smoking Cessation Clinical Trials

Smoking Cessation Programme in Workplaces in Hong Kong (Phase IV)

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

Smoking causes cardiovascular and respiratory diseases, cancers and diabetes, and it has been a leading risk factor for death globally. Despite the availability of smoking cessation services locally, most smokers do not use such services. Workplace is one of the most convenient platforms to provide smoking cessation services and over 55% of smokers are employed according to the local population-based survey. However, the effectiveness of a smoking cessation programme conducted in workplace is yet to be examined in Hong Kong, and the attitudes and practices of corporations in promoting smoking cessation are not clear. Thus, this study aims to examine the employers'/ managerial staff's knowledge, attitudes and practices in promoting smoking cessation in workplace and evaluate the smoking behaviors of participants before and after attending a smoking cessation intervention.
