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.
The primary objective is to demonstrate that treatment with etelcalcetide (AMG 416) is not inferior to treatment with cinacalcet for lowering serum intact parathyroid hormone (PTH) levels by > 30% from baseline among participants with chronic kidney disease (CKD) and secondary hyperparathyroidism (SHPT) who require management with hemodialysis.
Diabetes Mellitus (DM) is a well-recognized public health issue worldwide. DM can lead to many complications resulting in morbidity and mortality, approximately 70% of DM related deaths were attributed to cardiovascular diseases (CVD). Objectives: To develop 10-year risk prediction models for CVD, end stage renal disease (ESRD) and all-cause mortality among Chinese patients with DM in primary care. Hypotheses: 1. Patient socio-demographic, clinical parameters, disease characteristics and treatment modalities are predictive of 10-year risk of CVD, ESRD and all-cause mortality. 2. Risk prediction models developed from this study should have over 70% of discriminating power. Design and Subjects: 10-year retrospective cohort study. All Chinese patients who were clinically diagnosed to have DM and were receiving care in the public (Hospital Authority) primary care clinics on or before 1 July 2006 will be followed up until 31 December 2016. Main outcomes measures: For total CVD, CHD, stroke, heart failure, ESRD, all-cause mortality 1. 10-year incidence; 2. Predictive factors Data analysis: Two thirds of subjects will be randomly selected as the training sample for model development. Cox regressions will be used to develop sex-specific 10-year risk prediction models for each outcome. The validity of models will be tested on the remaining one third of subjects by Harrell C statistics and ROC Expected results: Risk prediction models will enable accurate risk stratification and cost-effective interventions for Chinese DM patients in primary care.
This study intends to investigate the three dimensional (3D) effect of bracing on the adolescent idiopathic scoliosis (AIS). In particular, it will look at the relationship between frontal deformity correction and changes in the sagittal profile and apical vertebral rotation (AVR) during bracing. The investigators hypothesise that if the thoracic frontal deformity can be controlled with bracing, there will be spontaneous correction of the sagittal plane and rotation deformity through coupling.
Aim to test the effectiveness of different incentive models for increasing the follow-up response rate in the current smoker subject.
The purpose of this study is to identify the flexibility radiograph(s) that can most accurately predict the curve behaviour after surgical correction of AIS. With these findings, the investigators hope to give further guidance for the selection of fusion levels and to incorporate different dynamic radiographs into the Lenke Classification, leading to a more universal application that can consistently lead to good surgical and clinical outcome.
Evidence suggests that affirming the self can help people to make changes in their health behavior. Typically, people affirm a personally-important value, but evidence suggests that affirming the values of family ("familial self-affirmation") might exert stronger effects. The aim of the present study is to examine the effects of familial self-affirmation versus standard self-affirmation versus a control group on smoking cessation.
To investigate the effect of caffeine on ocular circulation by using Optical Coherence Tomography and Optical Coherence Tomography Angiography. This study will evaluate blood supply to the inner and outer retina after consumption of 200mg caffeine capsule, in particular its effect in high myopes.
This study will examine the use of cognitive behavioural therapy (CBT) and acupressure in treating insomnia in Chinese adults. The main components of CBT for insomnia (CBT-I) includes psychoeducation, sleep restriction, stimulus control, cognitive restructuring, and relaxation. CBT-I is widely used in western countries but it fails to address patient preference among Chinese adults with insomnia, as demonstrated in a previous study examining the subjective experience of chronic insomnia in Hong Kong Chinese adults. The study revealed that Chinese adults showed distrust in hypnotics and preferred traditional Chinese medicine (TCM) which was believed to be more natural. In order to maximize the therapeutic effects of psychological interventions for insomnia, integrative medicine with a combination of CBT-I and TCM could be an alternative to address insomnia in the Chinese population. Acupressure, a non-invasive therapy, is commonly used in TCM. It is suggested that acupressure can induce relaxation and improve sleep quality. Some studies have demonstrated the separate efficacy of CBT-I and acupressure in treating insomnia. However, few studies have examined the effect of their combination.
This study aims to evaluate the effectiveness of the Smoke-free Teens Programme in strengthening youth's knowledge and attitude on smoking and health. The objectives are: i. To evaluate Smoke-free Teens' change in knowledge on smoking hazards, attitudes towards smoking, tobacco control and smoking cessation, and practices for promoting smoking prevention and cessation, ii. To evaluate the process and quality of smoke-free programmes organized by the Smoke-free Teens in their schools/community, and iii. To measure the number of people whom the Smoke-free Teens will deliver the smoke-free messages to.
Obstructive sleep apnea (OSA) is a common form of sleep-disordered breathing (SDB). Weight reduction has always been advocated in patients with OSA who are overweight and may lead to improvement in the severity of OSA. Previous study reported a randomized controlled trial of dietician-led lifestyle modification program (LMP) in 104 patients and found that LMP group had significantly more weight loss and reduced OSA severity, and the response was sustained after 8 months. This study is aimed to compare the effect of weight loss or CPAP alone on subclinical inflammation, insulin resistance and blood pressure in patients with obesity and moderate-to-severe obstructive sleep apnea, stratified according to the degree of craniofacial restriction. The study plans to recruit consecutive patients who have been referred to the Respiratory Clinic at the Prince of Wales Hospital with clinical suspicion of sleep-disordered breathing with specific study entry criteria including an age of 18 or more, body mass index (BMI) >25 kg/m2, and moderate to severe OSA diagnosed by home sleep study. Patients having conditions that will affect the serum level of hsCRP will be excluded.
