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 prostate gland is a clinically important male accessory sex gland and vital for its production of semen. Prostate cancer (PCa) is now ranked 3th in annual incidence of male cancer and ranked 5th for cancer-related death in men in Hong Kong which accounts for about 10.9 deaths per 100,000 persons. Its incidence is rising rapidly, almost tripled in the past 10 years. Fortunately, with the improvement in awareness of the disease and also increasing use of serum prostate specific antigen for early case identification, many patients are diagnosed at an earlier stage. However, unlike other malignancy, PCa is characterized by its slow progression nature. Therefore, some patients with low grade low volume disease might never suffered from PCa related complications or mortality. As a result, recent year, there is an increase use a more conservative approach, active surveillance (AS), for management of early prostate cancer. The principle of AS is selecting patients with low risk of disease and offered them regular monitoring, instead of radical local therapy, unless patient's cancer was noticed to progressing. By using this approach, patients might avoid possible complications related to treatment. Currently, people could use some clinical parameters, imaging and repeated prostate biopsy to assess and monitor the aggressiveness/ progression of PCa. However, these parameters suffered from defects, such as low correlation to the final PCa pathology or not readily repeatable for patients. Therefore, there is a need to identify more easy, safe and repeatable monitoring of the aggressiveness of prostate cancer. Exosome is genetic materials secreted by cells and could be measured in various body fluid. There are some studies suggested it is a potential marker for PCa diagnosis and monitoring. The aim of this study is to investigate the relationship of urinary exosome and the aggressiveness of prostate cancer.
This study was set out 1) Evaluate the impact of Diabetic Peripheral Neuropathy (DPN) and DPN-P (Diabetic Peripheral Neuropathic Pain) on the overall Quality of Life (QoL) in elderly with Diabetic Mellitus (DM) and 2) Evaluate the association between cognition impairments and DM in the elderly, and the contributions of DPN and/or DPN-P
Background: The relationship between the frequency of high-intensity interval training (HIIT) and the resultant adaptations is largely unclear. Purpose: This study examined the effects of different frequencies of HIIT compared to moderate-intensity continuous training (MICT) on body composition and cardiovascular biomarkers in overweight or obese adults. Methods: This study was a randomized, controlled, single-blinded trial. Fifty-six overweight or obese men aged between 18 and 30 years were randomly assigned to no-intervention control (CON; n=14), MICT performed thrice weekly (MICT×3/wk; n=9), HIIT performed thrice weekly (HIIT×3/wk; n=14), HIIT performed twice weekly (HIIT×2/wk; n=10), and HIIT performed once weekly (HIIT×1/wk; n=9). Each HIIT session consisted of 12 × 1-min bouts at 90% heart rate reserve (HRR), interspersed with 11 × 1-min bouts at 70% HRR (HIIT×3/wk: 69 min/wk; HIIT×2/wk: 46 min/wk; HIIT×1/wk: 23 min/wk). Aerobic capacity, resting heart rate, body composition, waist circumference, blood pressure, endothelial function, fasting blood glucose and lipids, circulatory adipokines and inflammatory biomarkers were examined at baseline, after 4 weeks and 8 weeks of intervention.
Osteoarthritis (OA) is a common and debilitating disease, For the majority of patients, pain in OA is episodic in nature. The experience of pain is generated or modified by nociception, neuropathic symptoms, psychological and personality factors, genetic influences, past painful experiences, comorbid conditions, and expectations related to future pain Previous studies have shown psychological well-being has been significantly associated with disability in patients with OA, and anxiety has been found to be associated with knee pain in women. Previous studies also found that there are large interindividual differences among persons with knee osteoarthritis (OA) with respect to psychological function. Psychological strengths and weaknesses are evaluated among new patient with osteoarthritis presented to joint replacement clinic, to facilitate our understanding of those patients need, and correlating with their radiological and clinical findings. Psychological strengths and weaknesses, positive and negative affects are evaluated in form of questionaires.

Our research question is: Are changes in sleep duration that occur naturally over school holidays associated with changes in blood pressure (BP) in sleep-deprived adolescents? In this study, the investigators will take advantage of changes in sleep duration that occur during school holidays in adolescents who are sleep deprived (>6 months' history of sleeping <8 hours per night during school term). The investigators will monitor the changes in ambulatory BP and sleep duration over a period of 3 weeks which consist of a week at school, followed by a week of holiday when natural sleep extension takes place, and then another week of school after the holiday. Sleep-wake cycle will be recorded throughout the whole study period with actigraphy and sleep diary. Twenty-four hour ambulatory BP monitoring will be performed on the same weekday during each study week, when salivary cortisol will also be collected. The primary outcome measure is the difference in ambulatory BP parameters between school term and holiday. A control group without sleep deprivation (history of sleeping >8 hours per night) will also be studied concurrently It is hypothesized that changes in sleep duration are negatively associated with changes in BP. If this study confirms our hypothesis, sleep extension can be used as a relatively inexpensive and simple behavioural intervention in the management and prevention of blood pressure abnormalities. More importantly positive results from this project will provide background information on which government and local school policy can be based and altered for the betterment of our youths.
This project examines the effects of implementing sport education model in university required physical education lessons on perceived physical literacy and physical activity levels of the students.
The incidence of prostate cancer is increasing in Hong Kong, as well as that of recurrent or metastatic prostate cancer. Androgen deprivation therapy (ADT) is the standard treatment for recurrent or metastatic prostate cancer, with side effects such as obesity, type 2 diabetes mellitus, metabolic syndrome, osteoporosis and cognitive impairment. With the improvement of treatment, the 5-year survival rate of recurrent and metastatic prostate cancer is up to 20%, and therefore increases the chances of developing such side effects. Due to the introduction of next generation sequencing, investigators have more knowledge of the microbiota in our body, particularly the gut microbiota. Different studies have related gut dysbiosis with obesity, type 2 diabetes mellitus and metabolic syndrome. If investigators can show that ADT is leading to gut dysbiosis, this could be a way in preventing or treating the side effects of ADT. This study aims to identify whether ADT in patients with prostate cancer will have different composition in their gut and urine microbiota.
The study is conducted to improve knowledge about the epidemiology of Lipoprotein(a) in patients with established cardiovascular disease (CVD).
Colorectal Cancer is the commonest cancer diagnosed for both genders combined in Hong Kong. In 2015 16.6% of all new cancer cases registered on the Hong Kong registry were cancer of colon and rectum. With recent development in oncological and surgical treatments for rectal cancer, many patients are receiving sphincter-preserving surgery with low colorectal or coloanal anastomosis to avoid permanent stoma. Up to 80% of patients who has undergone low anterior resection (LAR), suffer from severe bowel dysfunction post operatively. Patients may suffer from a wide range of symptoms from incontinence, frequency, and urgency to constipation and feelings of incomplete emptying. This combination of symptoms after LAR is referred to as Low Anterior Resection Syndrome (LARS) which is associated with negative impact on quality of life (QoL). Originally, it was thought that these symptoms were due to early postoperative changes. Many studies report that the majority of patients experience longterm changes in quality of life after LAR. Therefore, a large number of patients worldwide are suffering from unpredictable, poor bowel function postoperatively affecting their day-to-day activity and quality of life. The cause of LARS is often multifactorial and difficult to define. Unfortunately, there is no cure for LARS at present. This trial is designed to use Fecobionics, a new Hong Kong based innovation of a simulated stool, to provide new mechanistic insights regarding anorectal physiological function post low anterior resection to understand the condition better to improve their treatment options.
A multicenter, international prospectively collected patient cohort undergoing high-risk spinal cord level surgery or spinal osteotomy procedures will be enrolled to establish the incidence of intraoperative alerts in high-risk spinal cord cases, and explore factors associated with mitigating injury. Baseline, intraoperative, and postoperative characteristics, including demographics, radiological features, lower extremity motor score (LEMS), procedure, anesthetic agents used, and baseline blood pressure will be recorded for either adult patients or pediatric patients.
