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.
There is a lack of data in the literature about the use of low-molecular weight heparin (LMWH) as anticoagulation for nocturnal home hemodialysis (NHHD). This study aims to evaluate the efficacy and safety of LMWH, administered by infusion method, as compared to unfractionated heparin as anticoagulation for NHHD treatment.
This study investigated the effect of mycophenolate mofetil and cyclosphosphamide on lymphocyte subsets in patients with proliferative lupus nephritis. Patients with biopsy-proven Class III/IV+/-V LN were randomized to received: 1) prednisolone (0.8mg/kg/day) plus CTX (1.5-2mg/kg/d) for 6 months) followed by Azathioprine (AZA) (1-1.5mg/kg/d) maintenance; OR 2) prednisolone (0.8mg/kg/d) plus MMF (1g bd) for 6 months, followed by MMF (tapered according to clinical status) as maintenance. The lymphocyte subsets and serum cytokine profiles will be measured at 4-, 12-, and 24-, 36- and 48 weeks after induction treatment. The lymphocyte subsets and serum cytokine profiles will be compared between the two treatment regimens, and also correlated with subsequent risk of relapse.
The goals of this clinical study are to compare the effectiveness, safety and tolerability of study drug, tenofovir alafenamide (TAF), versus placebo in teens and children with CHB and to learn more about the dosing levels in children.
Orthognathic surgery is commonly performed for the treatment of dentofacial deformities. Yet, one of the most prevalent and long-term complication encountered is neurosensory disturbance thus impairing sensation to parts of the face. In Hong Kong, it has been reported that in patients receiving orthognathic surgery, 5.9% experience long-term neurosensory disturbance post-surgery. Melatonin is a neurohormone that is produced and secreted by the pineal gland in the brain. Its main physiological role in humans is to regulate sleep. Oral Melatonin supplements is also used in the management of jetlag and other sleep disorders. Recently, animal and human studies have shown Melatonin to improve tolerance to pain and to have a neuroprotective and neuroregenerative effect after nerve injuries. Hence, it is hypothesized that peri-surgical oral Melatonin supplement can improve neurosensory recovery after orthognathic surgery
This research project will provide insight into the efficacy and safety of aspiration therapy in the management of obesity and its comorbidities in the Asian population, and will determine if there is a role for this novel endoscopic device in the treatment algorithm of obesity in the investigators' local regions.
In Hong Kong, nearly 40% of adults were overweight or obese, and about 60% of total registered deaths were due to four major preventable non-communicable diseases. Many residents are lack of attention to personal healthy lifestyle and family holistic health. This project focuses particularly on the promotion of healthy diet and physical activities enhancement in families through the well-established community network of the Hong Kong Island Women Association (HKIWA). This project includes three major components: Train-the-trainer and -ambassador workshop, community-based family interventions, and public education events. It is expected that knowledge and skills of the community leaders and ambassadors are strengthened through the 'Train-the-trainer and -ambassador' (TTTA) workshops. Furthermore, they are expected to help the implementation of community-based family interventions and public education events on the personal and family holistic health of the community participants.
Chronic obstructive pulmonary disease (COPD) is a common disease worldwide with a high burden on healthcare resources. The prevalence of COPD varied from 11.4 to 26.1% according to a recent multi-city population study using spirometry. In Hong Kong (HK), the prevalence rates of COPD in the elderly population aged ≥60 years were 25.9% and 12.4% based on the spirometric definition of forced expiratory volume in 1s (FEV1)/forced vital capacity (FVC) ratio <70% and the lower limit of normal of the FEV1/FVC respectively. In 2005, the crude mortality rate of COPD was 29.1/100 000, while the crude hospitalization rate was 193/100,000 in HK. In HK, COPD ranked second as a respiratory cause for hospitalization. In those 75 years or older, the hospitalization rate for COPD was as high as 2,225/100,000. The economic burden of COPD on the society is enormous. Previous studies gave information on the overall morbidity, mortality and the prevalence of COPD in HK. One study compared the management of COPD patients in HK with other countries and found that COPD patients in HK were under-treated. No large scale study has looked into the details of COPD patients in HK, like their co-morbidities and how they are being treated and how these factors affect the readmission of these patients. Large prospective studies which incorporate all the potentially relevant variables are required to refine prediction of the important outcomes of AECOPD and thus to inform clinical decision making, for example on escalation of care, facilitated discharge and provision of palliative care.
Circulating tumor DNA (ctDNA) is a highly specific and effective biomarker for the detection of EGFR mutation status. We hypothesise AZD9291 is efficacious in patients with EGFR sensitizing mutations and T790M detected in plasma ctDNA. This is a prospective, open label, multi-centre single arm phase II study assessing the efficacy and safety of AZD9291 monotherapy in patients with stage IIIB or IV harboring sensitising EGFR mutation (exon 19 deletions or exon 21 L858R substitution mutations) and T790M who have progressed following prior treatment with an approved EGFR TKI. Approximately 106 subjects will be enrolled. All patients must have documented radiological progression on EGFR-TKI treatment and on the last treatment administered prior to enrolling in the study.
Introduction: Cerebral small vessel disease (SVD) is associated with age-related disabilities including dementia, depression, physical and functional impairment. Chinese are more prone to developing SVD than Caucasians. Physical exercise may improve multiple negative consequences associated with SVD. Objective and hypothesis to be tested: To examine the effects of a 24-week structured aerobic dance training on cognition, mood, physical and daily functions in stroke and dementia free older adults with SVD, and whether such effects are mediated through improved cerebral vasomotor reactivity (CVR), a marker of cerebral autoregulation which is impaired in SVD. Design and subjects: Rater-blind RCT comparing the effects of 24-week of structured aerobic dance training upon cognition, mood, physical and daily functions on 110 community dwelling, stroke- and dementia-free persons aged ≥65 with MRI evidence of significant SVD, defined as the presence of multiple (≥2) lacunes and/or early confluent or confluent WML. Interventions: Participants are randomized in a 1:1 ratio into a 24-week of structured therapist-led group aerobic dance training with home practice or simple stretching plus health education control group. Main outcome measures: Cognition, mood, physical and daily functions and CVR measured using Transcranial Doppler at baseline, weeks 12, 24 and 36. Data analysis: Intent-to-treat with multiple imputations with treatment efficacy analyzed using mixed effects models. Mediation effects of CVR between aerobic dance training and treatment outcomes tested using mediation models. Expected results: In persons with significant SVD, aerobic dance training improves cognitive, mood, physical and daily functions and such effects are mediated by changes in CVR.
Background: The interactions between human beings and wearable technology like activity trackers equipped with biometric sensors can be linked to health related new learning concepts/instructional methods supporting deep knowledge acquisition, situated, self-regulated and active learning. This personalized, long term interactions where specific information is pushed to the learner contributes to deepen the personal understanding related to the concept of and knowledge about health and has an impact on long term health action process. Design and methods: In order to understand the behavioural change process, a multiple case study including 35 higher education students in Hong Kong from an undergraduate course, BSc Exercise and Health is currently conducted. Each student uses a wearable device (activity tracker) over a period of five months, reflects weekly on emerging personal data, documents their thinking and action in the ePortfolio, and engages in an online forum. The participants enter their experiences with the biometric data, lifestyle adaptations (e.g. more steps), special situations (e.g. hike, heart rate changes during activity) and how these experiences lead to specific searches and actions on the web and/or in their real social network. The ePortfolio will allow the students to critically reflect on their progress and for the researchers to intervene at any time on the issues related to the participants' postings. EHealth literacy is used as indicator for the health action process of the participants. Evidence regarding change in eHealth at the beginning and end of the intervention will be collected with a standard questionnaire detecting eHealth their literacy scale. Scope: By reflecting on the information from their personal activity tracker and documenting it in their own ePortfolio, the students will continuously learn to analyse, search and critically assess health related personal and available digital information, organize it, present and discuss it with peers/tutor. This in turn will enhance critical thinking, raise questions about health related topics, stimulate further inquiry deepen their knowledge about personal health, inducing a healthier lifestyle.
