There are about 3753 clinical studies being (or have been) conducted in Hong Kong. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
As the global prevalence of food allergy steadily increases, tree nut (TN) becomes one of the main triggers of food-allergic reactions and food anaphylaxis. Since there is no effective cure, TN-allergic patients and their families must continue to live with this chronic, disabling condition while avoiding allergens and responding to allergic reactions with emergency treatment. An emerging experimental treatment for food allergy is oral immunotherapy (OIT). Tree nut OIT appears promising in preliminary studies but there are concerns about the high risk of adverse reactions to TNs used in the treatment. The rate of remission with TN OIT is also lacking. Identification of OIT regimes with increased efficacy and safety is urgently needed. The investigators revealed that boiled cashews had lower allergenic potential but retained mast cell reactivity. The aim of this proposed study is to investigate the efficacy and safety of a novel treatment strategy for TN-allergic individuals, whereby the investigators hypothesized that consuming increasing quantities of boiled cashews can induce desensitization/ remission to roasted tree nuts in children with cashew allergies.
This is a randomized controlled trial aimed to1) examine the effect of a self-administered acupressure intervention on head and neck cancer patients with xerostomia (primary outcome) relative to oral health education control; 2) examine the effect of self-administered acupressure on secondary outcomes, including quality of life and severity of symptoms of head and neck cancer patients; 3) evaluate patients' expectancy of acupressure; 4) explore the acceptability of self-administered acupressure for head and neck cancer patients with xerostomia. We hypothesize that self-administered acupressure has better effect on xerostomia for head and neck cancer patients comparing to oral health education. Acupressure will also benefit head and neck cancer patients on quality of life and severity of symptoms. Head and neck cancer patients may have good acceptability of self-administered acupressure.
To conduct a feasibility trial to examine the feasibility and acceptability of conducting a randomized controlled trial that evaluates the effect of the survivorship care intervention on patient-reported outcomes, defined as symptom distress and health-related quality of life.
Constraint induced movement therapy (CIMT) is based on the theoretical basis that constraining the unaffected limb following injury of the brain such as stroke can help overcome learned non-use. It comprises of constraint of the unaffected limb, massed tasks practice with the affected limb and a behavioral contract known as the transfer package whereby use of the affected limb is extended to the real-world situations. home-based rehabilitation is likely to be cost-effective, and it may reduce cost for patients in terms of hospital charges and transport fares. However, one of the major problems with the existing home-based CIMT protocols is that, they used number of hours spent carrying out tasks practice as the measure of intensity of practice, and it has been argued that, such method is not clear and it does not reflect the correct intensity of practice.

To audit and compare outcome between PWH, CUHK Medical Centre, and with other bariatric surgery centers in Hong Kong (Hong Kong Bariatric & Metabolic Surgery Registry) 3. To compare outcome with the regional/international center databse for benchmarking performance of HK bariatric surgery
Anterior cruciate ligament (ACL) tear is common. It accounts for over 50% of all knee injuries. Anterior cruciate ligament reconstruction (ACLR) with hamstring tendon (HT) autograft is the common graft choice for ACLR. However, the outcomes of donor site healing and recovery of muscle strength of HT are not satisfactory, resulting in hamstring muscle weakness and hamstring strength deficit during deep knee flexion, which may lead to hamstring strain after ACLR. Moreover, activation of the hamstring muscle is vital for maintaining dynamic knee joint stability and preventing excessive ACL shear forces. The presence of hamstring muscle deficits after surgery therefore affects the function of the reconstruction ACL. A previous study has reported that the hamstring muscle showed nearly 20% strength deficit at 4 months after ACLR with hamstring autograft Pulsed electromagnetic field (PEMF) treatment is a non-invasive therapy that has been shown to enhance muscle cell activity and accelerate tissue repair. In clinic, PEMF treatment has been reported to be safe. This study aims to conduct a double-blinded, placebo-controlled randomised clinical trial to investigate the effects of PEMF therapy for improving the tissue regeneration and strength of the HT donor site in ACLR patients with HT autograft.
Insomnia is a common complaint in peri-menopausal women. Acupressure might be a potential way to treat insomnia. Although acupressure can be self-administered, it is uncertain that whether the effects of self-administered acupressure are comparable to that of the practitioner-administered acupressure, due to the variability in patients' capability of mastering the acupressure technique and self-compliance. Previous studies seemingly suggested that self-administered acupressure may improve sleep quality, their conclusion on the efficacy of self-administered acupressure for insomnia was limited due to the lack of standardized subjective and objective sleep assessments and unclear diagnostic method of insomnia. To fill out this research gap, the proposed study will explore the effectiveness of self-acupressure for improving sleep in perimenopasual women using an RCT approach.
Osteoarthritis (OA) is a progressive disease of the synovial joints that causes joint pain and limitation of function resulting in considerable morbidity and impairment of quality of life. Knee OA is the most common type of OA, and symptomatic knee OA is highly prevalent among people aged over 50 years. With the increasing aging population, worldwide prevalence of knee OA is expected to be rising. The goals of treatment are to reduce pain, maintain or improve joint mobility, minimize functional impairment and improve quality of life. When conservative management, which includes structured land-based exercise programs, aquatic exercise, education and appropriate analgesic medications, fails, surgical approach can be considered. Unicompartmental knee arthroplasty (UKA) has become an alternative to TKA in cases of end-stage OA that are limited to a single compartment. Patients who underwent UKA have a quicker recovery, lower risk of complications, and improved range of motion. Physiotherapy rehabilitation is an integral part of good knee arthroplasty outcome. Conventional post-operative physiotherapy rehabilitation, which includes range of motion exercises, muscle strengthening exercises, balance and gait training, have been shown to have improvement in range of motion, muscle strength and functional outcome measures of patients. Recently, hydrotherapy is gaining its popularity as being incorporated into one of the components in the rehabilitation after knee arthroplasty. Studies reported that hydrotherapy could decrease pain, and improved physical function, strength and quality of life for patients after total hip or knee arthroplasty. However, there are no studies to investigate the effect of hydrotherapy on patients after UKA. With the increasing popularity of UKA as a surgical alternative in patients with end-stage single-compartmental OA, it is worth investigating the effects of hydrotherapy on the clinical outcomes of patients following UKA.
The trial is designed to examine whether Yizhi Baduanjin could slow down and improve in memory, logical thinking and cerebral function in patients with mild cognitive impairment (MCI). 30 MCI patients will be recruited and randomly assigned to Yizhi Baduanjin intervention group control group for 6 months. The primary outcome is changes in Montreal Cognitive Assessment (MoCA) questionnaire; other outcome includes Cognitive Function Assessment questionnaire.
Obstructive sleep apnoea (OSA) in children is a prevalent sleep disorder associated with a wide spectrum of morbidities, including neurobehavioural, cardiovascular, and metabolic complications. Positional OSA (POSA) is one of the distinct clinical phenotypes in which obstructive respiratory events occur predominantly while sleeping in the supine position. As the majority of the OSA events in POSA occur in the supine position, positional therapy has become a reasonable non-invasive treatment strategy. The primary objectives of our study are 1) To investigate the feasibility of positional therapy in children with positional OSA; 2) To investigate the efficacy of positional therapy in children with positional OSA. Hypothesis to be tested: 1) Positional therapy is feasible in children with positional OSA. 2) Positional therapy is efficacious in children with positional OSA by reducing the severity of the OSA as measured by the obstructive apnoea hypopnoea index. Design and subjects: A prospective case-control study. 20 children aged 6 to 17 years of age with positional OSA (POSA) will be invited to join the study. Primary outcome measures: Feasibility of the use of positional device therapy; the change in the OAHI between the baseline diagnostic PSG and the home sleep study using a positional device therapy. Statistical Analysis: Continuous data will be presented as mean and standard deviation or median with the interquartile range depending on its distribution, whereas categorical data will be shown as proportions. Changes in sleep study parameters between the baseline PSG and the home sleep study using the positional device will be compared using Wilcoxon signed rank tests. Within-subject differences in the secondary outcome parameters will be tested by paired t-tests, McNemar tests, and marginal homogeneity tests for continuous, dichotomous, and categorical data respectively. Expected results: Positional therapy is practicable and efficacious in children with positional OSA by reducing the severity of the OSA.
