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.
Objectives: To evaluate efficacies of two online and theory-based interventions [HC: health communication only and HC-MI health communication plus motivational interviewing (MI)] in increasing uptake of three doses of HPV vaccines within the 9-month follow-up period among Hong Kong Chinese men who have sex with men (MSM). Hypothesis: The HPV vaccination rate of the three groups would be in the order HC-MI group > HC group > Control group. Design and subjects: A three-arm randomized controlled trial (RCT) will be conducted (n= 624). With informed consent, anonymous surveys will be conducted at baseline, Months 3, 6, and 9. Inclusion criteria: 1) HK Chinese men aged >18, 2) oral or anal intercourse with men in the last six months; 3) no intention to leave HK for one month consecutively within the next 12 months, 4) regular internet access, and 5) willing to be followed up by phone. Study instruments: Structured questionnaires Interventions: 1) Group HC: exposure to web-based, interactive and theory-based health communication promoting HPV vaccination uptake; 2) Group HC-MI: same exposure as Group HC plus MI; and 3) Group C: exposure to online materials about mental health (control group). Main outcome measures: Uptake of three doses of HPV vaccination within the follow-up period. Data analysis and expected results: Intention-to-treat analysis, General Estimation Equation (GEE) and Cox regression methods will be used. Significance differences in HPV vaccination uptake rates will be found among the three groups.
This trial is to compare the efficacy of NOAC(Novel Oral Anticoagulants) with edoxaban vs. dual antiplatelet therapy (DAPT) for prevention of leaflet thrombosis (documented by cardiac CT imaging) and cerebral embolization (documented with brainDiffusion-weighted (DW) magnetic resonance (MR) imaging) in patients without an absolute indication for chronic oral anticoagulation (OAC) after successful transcatheter aortic valve replacement(TAVR).
This is a single center, inpatient, open label pharmacodynamic study to determine the effect of 5 g and 10 g doses of Sodium Zirconium Cyclosilicate (ZS) administered once daily (qd) for 4 days on potassium and sodium excretion in healthy Chinese subjects on a standardized, low sodium and high potassium diet.
Aims: To enhance mental well-being of adolescents, adults and their families by creating a positive, happy and joyful environment in the community. Targets: Parents aged 12-59 and their family members in Hong Kong. Methods: Joyful Parenting Pilot Project will adopt the public health and family-focused approach, under the brand name of "Joyful@HK Campaign". Evidence-based and Evidence Generating approach with vigorous study design, both qualitative (e.g. focus groups) and quantitative (e.g. randomised controlled trial), will be used to evaluate the overall programme effectiveness including follow-up of at least one month ("best science"). To ensure the practicability and sustainability of the CBEP, we will engage community partners with strong track records of "best practice" to design, plan, and implement the intervention. This project will use innovative and integrated positive psychology and public health theories and methods to plan brief, simple, and cost-effective intervention. Significance: By using "best science" in the design and evaluation of intervention programme, and the "best practice" of the partners' skills, experience and strong connection with service targets in the community, the intervention, if proven to be effective, for promoting sharing, mind and enjoyment and enhancing mental wellbeing can be further developed and widely disseminated to and adopted by the practitioners in the health and social service sectors for replication and improvement to benefit the whole population.
This study will evaluate the efficacy and safety of midostaurin in combination with daunorubicin/cytarabine induction, high dose cytarabine consolidation and midostaurin single agent continuation therapy in newly diagnosed patients with FLT3-mutated acute myeloid leukemia (AML).
Building upon our previous groundwork including the development of the FAMILY MOVE app and the pilot study, we will further evaluate the effectiveness of a simple parent-child partner exercise programme delivered by our FAMILY MOVE app on children's health-related quality of life through a single blinded randomized placebo-controlled trial (RCT). This RCT will sample 286 low-income parent-child pairs recruited from low income families in the community. Study participants will be randomized after baseline assessment by an independent statistician using computer randomization tool with 1:1 allocation ratio to either the FAMILY MOVE app intervention group or the HK FitNuts app control group. After both groups have completed the intervention study and follow up measurements at 1 month, 6 months and 12 months after intervention, the control group will receive the same FAMILY MOVE app. Outcome assessments will be conducted by a trained interviewer blinded to the subject group allocation at baseline, 1 month, 6 months and 12 months after intervention.
Malignant pleural effusion can occur in up to half of the patients with metastatic disease. It can cause shortness of breath to patients and so far there is no protocol on its management. The study is looking at patients with malignant pleural effusion and aims to identify its prognostic factors. Pleural fluid and blood analysis will be performed as in the standard of care and results will be collected at the start of diagnosis. This will not affect subsequent management plan. Patients' disease course will be followed up and progress data will be collected. Data will then be analysed to identify relevant prognostic factors.
Diagnosis and treatment of tuberculosis are often delayed in hospitalized patients, leading to worse outcomes. Rapid diagnosis of tuberculosis currently relies on microscopy and molecular techniques, which have limitations including low sensitivity and high cost.Highly sensitive diagnostic technique is needed for more accurate rapid diagnosis of tuberculosis to aid earlier initiation of antituberculous therapy. Detection of Mycobacterium tuberculosis (MTB) antigens in the bloodstream can potentially allow early diagnosis of tuberculosis. This study aims to evaluate the diagnostic performance of a novel assay using nanotechnology to detect MTB antigens in patients admitted to hospital with suspected pulmonary and/or extrapulmonary tuberculosis. Blood will be taken from eligible patients, and will be sent to the School of Biological and Health Systems Engineering, Arizona State University, for detection of 10-kDa culture filtrate protein (CFP-10) and the 6 kDa early secretory antigenic target (ESAT-6), two antigens specific for MTB, using the Nanodisk-MS assay. Investigations, including microscopy, culture, MTB polymerase chain reaction (PCR), and imaging, will be performed for diagnosis of tuberculosis. The diagnostic performance of Nanodisk-mass spectrometry (MS) assay will be evaluated.
Objectives To evaluate the efficacy of a program promoting HIV self-testing (HIVST) with online real-time counselling (HIVST-online) among men who have with men (MSM) in Hong Kong. Participants Inclusion criteria are: i) Hong Kong Chinese speaking males aged ≥ 18 years old, ii) self-report having had anal sex with at least one man in the last six months, iii) willing to leave contacts (mobile phone and/or social media account), and iv) having access to online face-to-face communication tools like Line, Skype, or Facetime. Those having been diagnosed as HIV positive will be excluded. Design A total of 350 eligible MSM will be recruited and invited to participate the program, including 120 HIVST-online users in a HMRF project (ref#11120791) (re-testers), and 230 new prospective HIV testers (new-testers) through outreaching at gay venues (bars and saunas), internet and social media, and referrals made by participants. A brief baseline telephone survey will be conducted among all participants they are exposed to the components of the health promotion program. All participants will be followed up at Month 6 by phone/social media for outcome and process evaluation. Main outcome measures The primary outcome is whether the participant has taken up our HIVST-online service during a 6-month follow-up period. This behavioural outcome will recorded objectively by the HIVST administrators. Among those who had not taken up HIVST at Month 6, they will be contacted by social media to ask a few questions to assess secondary outcomes, which include: 1) whether having taken up any form of HIV testing other than HIVST-online and 2) intention to take up HIVST-online or other forms of HIV testing in the next six months. Process evaluation of the health promotion components (e.g., online video, MI, and project webpage) and the HIVST-online service (e.g., delivery of the HIVST kits, appointment making with HIVST administrators, pre- and post-test counseling) will also be conducted.
Introduction: Chronic obstructive airway disease (COPD) is common condition in old age and the perception of hypoxia is often impaired in some COPD patients. Therefor it is need to monitor oxygen saturation in older people with COPD. A finger wearable device has been developed to measure oxygen saturation and heart rate variability. The investigators therefore will perform a cross sectional study to evaluate the clinical application of this finger wearable device in the detection and management of COPD in older people. Subject and method: 100 COPD subjects and 200 community dwelling older people without diagnosis of COPD will be recruited. Physical functioning and lung function test will be performed. Subjects will wear a finger wearable device to monitor heart rate variability and oxygen saturation and wear another wrist wearable device (Actigraph) to monitor physical activity and sleep for 6 days at the same time. Statistical analysis: Statistical analysis will be made to examine the potential association between oxygen saturation and physical activity and sleep, and the association between heart rate variability and physical activity and sleep.
