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.
This prospective, randomised, double-blinded cross-over study aims to compare the effectiveness of auricular acupuncture (AA) with placebo sham acupuncture (PSA) in reducing dental anxiety, pain perception and physiological responses to stress and anxiety among adolescents during orthodontic extractions. Adolescents aged between 10-19 years old who are undergoing orthodontic treatments requiring bilateral premolar extractions will be invited to complete a validated questionnaire to record their dental anxiety level, oral health knowledge, attitudes, practices, demographic and socio-economic factors. During orthodontic extractions, physiological responses including heart rate and oxygen saturation will be measured with a fingertip pulse oximeter throughout the process. The participants will be allocated randomly to one of the two groups in the study. Group 1-- auricular acupuncture in their first orthodontic extraction visit and placebo sham acupuncture in their second orthodontic extraction visit. Group 2-placebo sham acupuncture in their first orthodontic extraction visit and auricular acupuncture their second orthodontic extraction visit. Both acupuncture interventions will be carried out by a Hong Kong registered Chinese medical practitioner. The acupuncture needles are kept in place for 20 minutes to exert its effect before the dental extraction. Placebo sham acupuncture will not cause any harm, but the acupuncture points have no reported effect on stress relief. The extraction of premolars will be performed by a Hong Kong registered dentist. Local anesthesia is injected to numb the respective site, then the premolar will be removed with forceps, followed by stopping the bleeding by biting firmly on gauze.
Left main coronary artery (LMCA) is a major branch of coronary artery and supplies a large bulk of myocardium. Revascularization by either surgical coronary bypass grafting (CABG) or percutaneous coronary intervention (PCI) is recommended for significant unprotected LMCA disease, with CABG being preferred if there is significant involvement in other coronary arteries1,2. CABG has been demonstrated to confer survival benefit over medical therapies patients with LMCA in earlier clinical trials3,4,5. However, these trials were performed before the wide adoption of modern medical therapies such as antiplatelet and statin. Antiplatelet agents, for example, was only used in 32% of all patients in the Coronary Artery Surgery Study3. Modern day medical treatment for stable coronary artery diseases have been shown to be non-inferior to revascularization in both the COURAGE and ISCHEMIA trials6,7. However, patients with LMCA involvement were mostly excluded from both of these studies. In Hong Kong, the average waiting time for an elective CABG for stable patients with LMCA is around 18 months, during which time the patients are treated with modern medical therapies including high-intensity statin and antiplatelet.
There have been previous reports of using High-intensity focused ultrasound (HIFU) as a feasible thermal ablative treatment for relapsed Graves' disease. In recent years, radiofrequency ablation (RFA) has become another promising alternative for thermal ablation of benign thyroid nodules. RFA has the advantage of avoiding a surgical scar, organ preservation and being an ambulatory procedure. It utilizes a small caliber radiofrequency electrode, which is inserted into the thyroid gland percutaneously. The active tip of the RF electrode would induce frictional heat in the surrounding tissue, causing a thermal ablative effect. The direct application of energy of RFA to tissue is different from that in HIFU, in which energy is transmitted through the skin of the participants from the transducer. Studies of follow-up after RFA of Graves' disease have not been published. Given the previous successful experience with HIFU, the investigators would like to explore the feasibility, safety and efficacy of RFA as an alternative thermal ablation option for relapsed Graves' disease. Thus, the purpose of this prospective study is to assess the efficacy and safety of US-guided RFA for the treatment of relapsed Graves' disease.
The research protocol outlines a pilot study for a home-based and group-based tele-exercise program designed for breast cancer survivors. The study is a randomized controlled trial (RCT) led by Dr. Yang Gao from Hong Kong Baptist University, with multiple other investigators from Kwong Wah Hospital and the university itself. Breast cancer is identified as the most prevalent cancer among women globally and in Hong Kong. The document states that adjuvant therapies post-surgery, such as radiation and chemotherapy, can have both short-term and long-term side effects, which may affect the survivors' physical and mental health. The study is based on evidence that physical activity levels often decrease after a breast cancer diagnosis and that exercise can mitigate the side effects of treatment, improving health and quality of life. The pilot aims to test the acceptability and feasibility of a 12-week tele-exercise program that combines psychological theories and behaviour change techniques, transitioning from supervised to unsupervised exercise to build sustainable exercise habits. The study will enrol 24 patients, randomly assigning them to an intervention group or an active control group. The intervention group will receive 12 online training sessions plus 4 psychological counselling sessions, whereas the control group will receive educational essays on exercise and health. The training sessions for the intervention group will include various exercises with increasing intensity and duration over the 4 weeks, monitored by a pulse oximeter to ensure exercises are done at the appropriate heart rate. The sessions will be led by qualified coaches, with Dr. Gao overseeing quality control.
The current study aims to implement the Activity Breaks intervention and evaluate its effectiveness on outcome measures of executive function (EF), physical activity (PA), and sedentary behaviour (SB) in school children.
The main objective of the study is to assess the pharmacokinetics (PK) of AMG 133 after a single subcutaneous (SC) administration in overweight or obese Chinese participants.
Compare the effects of prefabricated foot orthoses with and without metatarsal pads on pain intensity in the 2nd to 4th metatarsophalangeal joints, foot and ankle functional abilities as well as the occurrence of plantar callosities among patients with central metatarsalgia.
The purpose of this study is to estimate the effect size of the Chit-Chat intervention on ACP engagement among family members of older adults with multi-morbidity.
Consequences of the compromised vascular system in diabetes mellitus (DM) are among the most devastating complications. Reduction in blood flow and oxygen uptake of skeletal muscle leads to muscle fatigue and impaired skeletal muscle post-exercise adaptation. Recent studies showed that intermittent vacuum therapy (IVT) augments the blood flow of the foot in people with DM. This pilot study investigates the effects of combined IVT and aerobic exercise in improving lower limb muscle oxygenation and distal circulation in individuals with DM. Positive results of the study shed light on strategy that enhances the effectiveness of aerobic exercise in people with DM.
This is a prospective parallel group, double-blinded randomized controlled trial. Subjects are randomized into two groups - the intervention group and waitlist control group. Subjects received resistance, aerobic, flexibility and balance exercise training; and nutritional supplement containing β-hydroxy β-methylbutyrate (HMB). The intervention group would first receive the intervention during the 12-week study period. Meanwhile, the waitlist control group would receive 12 weeks of conventional care. After the study period, they would receive the same intervention.
