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.
Introduction: Diabetic mellitus (DM) is a prevalent disease in Hong Kong (HK) and diabetic retinopathy (DR) is one of the most common complications of DM. Screening for DR is a cost-effective method to identify patients who are at risk of vision loss so that timely treatment can be provided to patients. In Hong Kong, the Hospital Authority has recently set up screening services (RAMP) in the government outpatient clinics and all DM patients attending these clinics will be screened at least once every two years and some every six months, according to their individual risks. However, those diabetic patients who attend the private sector for their primary care may not have access to this service. Aim: This study from the University of Hong Kong aims to determine the characteristics of a sustainable approach to setting up an effective and quality-controlled screening service for DR in the private primary care sector of Hong Kong and to estimate the potential benefit to be gained in terms of impact on avoidable vision loss, costs of care and potential for further development of this model in chronic disease care. Methods:A screening centre is being set up and a randomised study carried out in which screening will be offered at three different fee levels to subjects recruited by their general practitioner (GP). The following data will be collected (a) willingness to attend screening at the different fee levels (b) screening findings in terms of DR and other eye diseases (c) risk factors and other characteristics of those screened and unscreened. The information will allow us to estimate the level of fee which best combines effectiveness with sustainability in the longer term.
To assess the infective etiologies by quantitative polymerase chain reaction (qPCR) of acute exacerbation of COPD and asthma who required hospitalization. To identify the HRV subtypes that are associated with COPD and asthmaexacerbations. To assess if the infective aetiologies have associations with the clinical outcome of the patients.
The main purpose of this study is to determine whether nivolumab + chemotherapy is effective as compared to chemotherapy in the treatment of patients with EGFR mutation, NSCLC who failed first line (1L) or second-line (2L) EGFR TKI therapy.
The purpose of this study is to determine whether Nivolumab is effective in the treatment of Relapsed/Refractory Primary Central Nervous System Lymphoma (PCNSL) and Relapsed/Refractory Primary Testicular Lymphoma (PTL)
The primary objective of this study is to evaluate the safety and tolerability of GS-9674 in participants with nonalcoholic steatohepatitis (NASH).
According to the Social Welfare Department statistics, Kwun Tong has been ranked as the highest for the reported cases of elderly abuse (12.3%), the second and fourth highest for the reported cases of battered spouse (9.2%) and child abuse (7.9%) respectively. To strengthen family well-being in the Kwun Tong community, the investigators adopt a community-based participatory (CBP) approach and implement a community-based "Learning Family" campaign in Kwun Tong district with the investigators collaborator, the Christian Family Service Centre (CFSC). The campaign aims to promote family health, happiness, and harmony (3Hs) through cultivating cooperative and self-regulated family learning culture in Kwun Tong district.
Objectives: To examine the efficacy and safety of electroacupuncture (EA) combined with auricular acupuncture (AA) in reducing post-operative pain in patients following abdominal surgery for gynecological diseases. Hypothesis: Acupuncture is effective and safe to reduce postoperative pain during the first 5 days following surgery as compared to a sham control. Design and strategy: This is a randomized, placebo-controlled, subject- and assessor-blind trial. Seventy-two subjects will be recruited and randomized (in 1:1 ratio) to receive either acupuncture treatment or sham control. Subjects in both groups will undergo standard operation procedure and receive post-operative analgesics based on usual care. Study instrument: A 10-point pain Numerical Rating Scale (NRS) will be employed as a primary outcome assessment. Intervention: Subjects in the treatment group will receive EA combined with AA within two hours before operation, post-operation upon arrival to the ward and once a day for the subsequent 5 days. Subjects in the control group will receive non-invasive sham procedure in the same schedule. Main outcome measures: Primary outcome: NRS pain scores will be measured upon recovery, hourly at 6 hours after surgery, then 4-hourly until day 2, 6-hourly until day 3 and once daily until discharge. Secondary outcome: Morphine consumption, post-operative syndromes, quality of recovery questionnaire, SF-6D, EQ-5D-5L and adverse events will be documented and compared between groups. Data analysis: Pain intensity during the first 5 days will be calculated by Area Under the Curve (AUC) of NRS pain scores. AUC between the two groups will be compared by Student's T-test. Expected outcome: AUC of the acupuncture group is expected to be significantly lower than sham acupuncture group.
This study intends to use Play Intervention for Dementia (PID) to promote cognitive functions of people with early to moderate dementia. This is a cluster randomized controlled trial aims to recruit 38 participants from two study sites. Participants will be randomly allocated into intervention or wait-list controlled groups. Both groups will receive the same content of PID programme at different time. The PID consists of 12 weekly sessions. Each session lasts for 45-75 minutes. The PID will be facilitated by a play specialist, trained elderly volunteers, and centre staffs. Cognitive functions will be evaluated with Montreal Cognitive Assessment, Fuld Object Memory Evaluation and Modified Verbal Fluency Test, conducted by a trained research assistant blinded to group allocation. Centre staffs (not involved in the PID) will be interviewed. Every alternate session will be video-taped for understanding the experience of the participants in the PID programme.
Smoking is highly addictive and quitting is difficult. Relapse is common because of withdrawal symptoms such as craving, headache, mood change and irritation. In addition to pharmacotherapy, exercise can acutely reduce craving, withdrawal symptoms and negative affect in regular smokers. Exercise effectively reduces negative affect and attentional bias towards smoking, and hence might relieve craving.Instead of long duration (30+ minutes) exercise, short-bout exercise is more easily adhered to in daily living and achieves similar health gain as long-bout exercise.Handgrip, which enhances training of hand-griping strength, is a common short-bout exercise tool used for lowering blood and arterial pressure.Therefore, this exercise tool might also raise smokers' interest to initiate this simple and effective exercise for quit attempt. This RCT study was proposed by using short-bout exercise (intervention) and healthy diet (control ) for smoking cessation, targeting adult clients who enrolled in smoking cessation service of ICSC, smoke 10 cigarettes or more a day when they initially receive the treatment from ICSC, can access to Internet by using smart phone and interested in participating in an exercise/diet program for smoking cessation. All the participants will be randomized the subjects to one of the RCT groups by using sequentially numbered, opaque sealed envelope method. Participants from both groups will be helped to install a phone application (App) in their smartphone which can send reminders of doing exercise or healthy diet. Also, the participants will enter their smoking and craving data by the App by answering the automatic pooped daily questionnaire. Telephone follow-up will be conducted at 2,6 and 12 months.
This is an observational study using Bronchial-alveolar lavage (BAL) as specimen for GeneXpert, a real time polymerase chain reaction (PCR) test for detection of tuberculosis (TB). Patients suspicious of TB, who require bronchoscopy as part of the investigation procedures, will be recruited for this study over a period of 18 months. Clinical likelihood of TB will be systematically scored according to various clinical parameters. This will determine the pre-test probability. Clinician will decide if anti-TB treatment is to be started and patients will be followed up for a minimal of 18 months. Sensitivity, specificity, positive, negative predictive values and the respective likelihood ratio will be calculated accordingly.
