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 study investigates the effects of exercise on older people's cognitive and affective functions, and the possible underlying neurobiological pathways.
This study aims to prospectively assess the asthma control and management of asthma patients who are on step 4, 5 asthma of GINA in Hong Kong (on at least medium-dose ICS-LABA as controller therapy for asthma) and also observe their exacerbations over 2 years. In addition, this study will also assess patients who are on biologics for their suitability and outcome. The investigators hope this study will be able to provided data regarding the management and outcome of patients who have difficult-to-treat and severe asthma. The investigators plan to build a biologic registry for asthma that would be able to help local doctors to gain experience to the use of these new and expensive medications. This is a multi-centre study involving public hospitals in Hong Kong. This study is important as this will generate local data for healthcare planning for severe asthma in Hong Kong.
The Hong Kong Jockey Club Charities Trust has supported CUHK to launch a three-year project 'CUHK Jockey Club HOPE4Care Programme' to implement four evidence-based advanced rehabilitation technologies in 40 local elderly day care centres and rehabilitation centres, to benefit the community. Our research team had developed the "Augmented Reality (AR) Rehabilitation Training System" that can be used as tools for rehabilitation by individuals who have suffered from a stroke or elderly. The system facilitates an active rehabilitative exercise.
tACS has the potential to directly induce cortical alterations in the intrinsic neural oscillation at specific frequencies, and the brain could mirror the induced frequencies of the external source of oscillations from the stimulation. Hence, tACS with matching stimulation frequency could be an effective means of enhancing brain oscillatory activity to potentially induce synaptic plasticity for restoration of damaged brain functions. However from the existing studies of applying tACS over the M1 in healthy and diseased brains, there is a wide range of applied stimulation frequencies and varied neuromodulation effects on motor behavior or cortical excitability at different frequencies. In this proposal, subject-specific stimulation frequency and latency will be identified.
Objectives: The aim of this randomised controlled clinical trial is to evaluate surgical accuracy and efficiency of computer-assisted jaw reconstruction using 3D-printed patient-specific titanium surgical plates versus conventional plates. Hypothesis to be tested: The investigators hypothesize that compared to conventional surgical plates, 3D-printed patient-specific surgical plates improve surgical accuracy and efficiency of computer assisted jaw reconstruction. Design and subjects: This is an open-label, prospective, double-arm, and single-centre randomised controlled clinical trial. Patients with maxillary or mandibular neoplastic, inflammatory and congenital diseases who require immediate or secondary reconstructive surgery will be invited to participate in the study. Study instruments: 3D-printed patient-specific titanium surgical plates and conventional plates. Main Outcome Measures: The primary endpoint is the accuracy of reconstruction. The secondary endpoints include the accuracy of osteotomy, reconstruction time, total operative time, intraoperative blood loss, length of post-operative hospital stay, and postoperative adverse events. Data analysis: The accuracy parameters, reconstruction time, total operative time, intraoperative blood loss, length of post-operative hospital stay will be presented as mean values with standard deviations. The post-operative adverse events will be calculated and presented as frequency with standard deviation. Expected results: This randomised control trial will prove improved accuracy and efficiency of reconstruction using 3D printed patient-specific titanium surgical plates. This study is expected to provide high-level evidence to push forward the popularity of using 3D medical printing technology in surgical field.
Flow dynamics in the liver is altered in different hepatobiliary and cardiac pathologies, causing changes in hepatic vasculatures sizes and flow pattern changes which can be assessed by ultrasound (USG) study. Before one can use these measurements and observations to diagnose pathologies, a clear grasp of normality is crucial. In the field of pediatrics, this is particularly challenging as the normal range of measurements may change with age, weight, height, gender and race of children. Taking hepatic veno-occlusive disease as an example, current literature is conflicting regarding whether sonographic findings show consistent association with the disease. Sonographic findings therefore now have limited role in contributing to the diagnosis. This may be related to the lack of a robust age corrected normal range of measurement for reference. Existing literature shows that the normal portal vein diameter varies with age, weight and height and possibly gender. Literature for normal measurements of hepatic vein and hepatic artery in children is lacking. In this study, the investigators aim to conduct a prospective, cross-section observational study to establish the normal measurements ranges of hepatic vein, hepatic artery and portal vein in healthy children in the investigators' locality. Flow patterns, including qualitative assessment and quantitative measurements of resistive index and flow velocities will also be assessed. These age corrected normal measurements will be very helpful in the diagnosis and follow-up of hepatobiliary and cardiac pathologies associated with alterations in dynamics of hepatic circulation.
This randomized controlled trial aims to examine the efficacy of two integrative body-mind-spirit interventions, compared to a health education active control, in promoting adaptive emotional regulation and quality of life of children with eczema and their parent caregivers in Hong Kong. It also aims to examine the interdependent associations between children and their parent caregivers' baseline primary outcomes and the post-intervention changes in primary outcomes.
The ELASTO-SURGERY study aims to evaluate the prognostic role of portal hypertension evaluated by non-invasive methods in predicting post-operative morbidity (at 90 days) and mortality (at 365 days) in patients with advanced chronic liver disease undergoing elective extrahepatic surgery.
Management of ACLF is mainly supportive. The poor outcomes lead physicians to consider liver transplantation as an option, even if controversial. In sicker recipients, LT results in immediate survival, but poor medium-term survival rates in some studies. The scarcity of deceased donors obliges to maximize LT success. Alternative strategies, as living-donor LT, should be explored. LDLT has impressive results in Eastern centers, but it is restrained in Western countries, due to potential life-threatening complications in the donor.
This study is aimed to elucidate the factors affecting the remodeling process of arteriolosclerosis under current practice recommendations. Such knowledge may improve the understanding of cerebral small vessel disease (cSVD) mechanism, define pharmacological therapy and suggest treatment target.
