There are about 3691 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.
The treatment for fistula-in-ano (FIA) remains a challenge to General and Colorectal Surgeons Worldwide. A variety of surgical treatments have been described for high anal fistulas, but none offers the panacea of fistula eradication with guaranteed preservation of continence. This study compares Collagen paste injection to mucosal advancement flap for the treatment of fistula-in-ano.
The proposed study aims to investigate the efficacy of the Dynamic Temporal and Tactile Cueing treatment in Cantonese-English bilingual speakers with childhood apraxia of speech.
This prospective randomized controlled trial will be conducted to investigate Clareon intraocular lens (IOL) stability in vitrectomy patients. The investigator plans to target the patients undergoing cataract surgery. A randomized study will be conducted with 2 arms, one with Clareon IOL versus a second arm using the Tecnis 1 In this non-inferiority study, the investigator will compare Clareon IOL from Alcon with the existing Tecnis 1 IOL from Precision Lens which is the commonly used intraocular lens in combined vitrectomy cases in Hong Kong.
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.
Objectives: To evaluate the effectiveness of active opportunistic screening using point-of-care capillary Hemoglobin-A1c (POC-cHbA1c) testing, compared to venous HbA1c (vHbA1c) testing, in improving detection of type 2 diabetes mellitus (T2DM) among at-risk primary care patients. Design: Pragmatic cluster randomized controlled trial. Setting: 8 public primary care clinics in Hong Kong. Participants: A minimum of 776 patients (97 per clinic) who have ≥1 risk factor for T2DM, but no known diagnosis of DM or DM screening in the past 12 months. Intervention: Participants at intervention clinics (n=4) will be offered free POC-cHbA1c testing on-site, immediately informed of test results and DM risk, and scheduled for confirmatory oral glucose tolerance test (OGTT) if screened positive (i.e. HbA1c≥5.6%). Participants at control clinics will be offered free vHbA1c testing scheduled on a separate day, informed of test results and DM risk via phone, and scheduled for confirmatory OGTT if screened positive. Main outcome measures: Primary outcomes are uptake rate of POC-cHbA1c versus vHba1c testing, and difference in proportion of T2DM detected between intervention and control groups. Secondary outcomes include number-needed-to-screen to detect one more T2DM case. Data analysis: Participants' characteristics and test uptake rates will be summarized by descriptive statistics. Difference in the proportion of T2DM detected between groups will be compared using Chi-squared test. Number-needed-to screen to identify one additional patient with DM will be calculated. Expected results: A greater proportion of T2DM patients will be detected by POC-cHbA1c than vHbA1c due to a higher screening test uptake rate among the studied population.
The aim of the study is to examine the air dispersion pattern and the environmental influence of open airway suction in general ward setting. Secondly, the study is aimed at identifying a simple & practical enclosure device in general ward. Suction will be performed in manikin in supine lying. Nasopharyngeal suction will be performed by physiotherapist with working experience more than 1 years. Besides, surgical mask & enclosure tent will be adopted as the enclosure barrier device in this study. Research Question 1. To assess the extent of the environmental contamination during coughing and simulated airway suction 2. To measure the air particle count during coughing and simulated open airway suction. 3. To evaluate how effective the enclosure barrier in reducing the air particle dispersion during open airway suction.
To examine the immediate and sustained effect of a 4-week combined volitional and reactive step training on fall risks in community-dwelling older fallers.
Lung cancers patients often experience multiple symptoms (e.g. fatigue, dyspnea, distress, depression, sleep disturbance). The current study attempts to explore the efficacy of the Smart Self-Management Support Programme (3S) in improving quality of life of patients using self-management support programme with mobile devices.
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.
Globally, 10 million new traumatic brain injury (TBI) cases are estimated annually, with mild traumatic brain injury (mTBI) accounting for 75-90% of all TBI cases. It is estimated that 40-80% of individuals with mTBI may experience the post-concussion syndrome (PCS), which is characterized by a range of physical, cognitive, and emotional symptoms. Although the underlying basis of cognitive dysfunction of patients with persistent PCS remains to be clarified, converging evidence shows that the clinical symptoms is underpinned by abnormal neural information processing as a result of axonal injury due to mTBI. Recent studies have demonstrated abnormalities in both structural and functional cortical connectivity, and a loss of cortical excitability-inhibitory (E/I) balance after TBI. Yet, there is no consensus for treating chronic symptoms of concussion, and PCS remains a chronic and highly disabling condition. One potential treatment option is transcranial direct current stimulation (tDCS), a non-invasive brain stimulation technique that has been shown to modify behavior by enhancing connectivity between targeted brain areas. However, research on the therapeutic effect of tDCS on PCS symptoms is limited, and the neurologic mechanisms underlying its effects are not well understood. The proposed study aims to address these knowledge gaps by examining the effects of tDCS on the central nervous system function in patients with PCS, with a specific focus on functional cortical connectivity and cognitive functions such as processing speed and executive function. The study also aims to add value to existing evidence by potentially opening new directions for designing intervention programs for the treatment of PCS after mTBI.
