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.
Background: Functional dyspepsia (FD) is one of the commonest digestive disorders. The pathophysiology of functional dyspepsia is uncertain. Risk factors include genetics, gender, age, helicobacter pylori infection, etc. However, few reported the association of genetic contribution to the development of FD and mood disorder. Indication: Functional dyspepsia patients Study center(s): Prince of Wales Hospital, Hong Kong Aims: - To evaluate genetic factors on development of functional dyspepsia & common mood disorders - To evaluate genetic factors on the severity of function dyspepsia & mood disorders - To develop a diagnostic test for classification of functional dyspepsia by plasma ghrelin and serotonin expression - To collect sleep data for future use - To save blood sample for future retrospective diagnostic or genetic examination Study design: Case-control cross sectional study Number of subjects: Total of 1200 subjects (300 FD patients + 300 relatives of FD patients FDR) and (300 Controls + 300 FDR) Patient population: Functional dyspepsia patients age 18-60 Duration of study: 1 May 2012 - 30 April 2013 Primary variable(s): Genetic polymorphisms of targeted genes, plasma ghrelin and serotonin expression Secondary variable(s): FD global symptom assessment and symptom scores Number of visits: 1 Hypotheses: - Shared genetic factors contribute to the development of FD and common psychological disorders - FD patients contribute to suppression of plasma ghrelin and serotonin expression compared to healthy controls
Background Functional community ambulation not only requires a critical level of postural control and walking skills, but also the ability to engage in cognitive tasks while walking (i.e., dual-task walking) and adapt to the constantly-changing environmental contexts. There is evidence showed that dual-task balance and gait performance is significantly impaired after stroke. Increasing evidence also suggests that dual-task balance and gait performance is useful for predicting falls among individuals with stroke. Considering the high clinical relevance of dual-task balance and gait performance, it is essential that stroke rehabilitation adequately addresses dual-task deficits. Developing specific dual-task balance and gait training to enhance dual-task performance is thus necessary to promote community ambulation and reintegration. Study Aim The aim of this Introduction Many individuals after stroke continue to cope with residual physical impairments after discharge from hospital. One of the major problems encountered by people after stroke is community reintegration. Functional community ambulation not only requires a critical level of postural control and walking skills, but also the ability to engage in cognitive tasks while walking (i.e., dual-task walking) and adapt to the constantly-changing environmental contexts. There has been an increasing awareness of the importance of dual-task gait performance in community-dwelling individuals with stroke in the past few years. There is evidence showed that dual-task balance and gait performance is significantly impaired after stroke. Increasing evidence also suggests that dual-task balance and gait performance is useful for predicting falls among individuals with stroke. Considering the high clinical relevance of dual-task balance and gait performance, it is essential that stroke rehabilitation adequately addresses dual-task deficits. Developing specific dual-task balance and gait training to enhance dual-task performance is thus necessary to promote community ambulation and reintegration. Study Aim This will be a single-blinded randomized controlled trial (RCT).The aim of this study is to examine the efficacy of a dual-task exercise program on cognitive-motor interference in balance and walking tasks, balance self-efficacy, participation in everyday activities, community reintegration and incidence of falls among individuals with chronic stroke.
Acute pain service (APS) was introduced in 1990s at Queen Mary Hospital (QMH) as other countries. With accumulation of experience and clinical evidence, APS has been well established. A study conducted in 1997 suggested that monitoring, management protocol and nursing experience were mandatory to the safety for APS. Our recent study showed that pain relief of our post-operative patients using patient controlled analgesic with morphine was still not adequate. The results has driven us to continue the improvement of post-operative outcomes for our surgical patients. Tolerability and safety are always our concerns for patients using our APS. Therefore, the investigators aim to conduct this retrospective study in order to assess if the tolerability and safety of our present APS are adequate or not. The study results will help us to further improve our APS at QMH if necessary.
This clinical trial is the first study to apply neurodynamic mobilization, a nervous system specific therapeutic exercise, on patients with rheumatoid arthritis(RA). Objective of the study is to find out the effect of neurodynamic mobilization for joint inflammation in patients with RA.
To test the hypothesis that hypertensive patients who participate in smart phone based telemonitoring of BP will conduct more home blood pressure monitoring, better self management behavior and greater reduction in blood pressure and better self management behaviour from baseline to 6 months follow up than those patients receiving usual care.
Study hypothesis: Childbearing couples who receive the father inclusive psychoeducation program will have: (a) a lower level of depressive symptoms, (b) a higher level of marital relationship, and (c) a higher level of quality of life at 6 weeks, 6 months and one year postpartum than those who receive the usual perinatal care.
Pain is the way our brain interprets certain bodily sensations. It is very difficult to describe or to put into words as perception and tolerance of pain varies widely between individuals. It is known that age, gender and past experience and memory of past experience all contribute to patients' feelings of discomfort and tolerance of pain, but the reason why some patients actually do not experience any pain at all post surgery is still unknown. Because pain affects every person at some point in their lives, it is of utmost importance that we can find more effective analgesic methods, and provide analgesia tailored to an individual's need as well as discovering new methods which may be able to identify those individuals who are more prone to suffering serious, or chronic pain. It has been proposed that epigenetic modifications may play a role in sensitivity to analgesia and response to trauma, such as post surgery. The effects of epigenetic changes on key genes and the role this plays in analgesia sensitivity and pain perception is deserving of further research. Epigenetics is a growing field of study in which there are genetic modifications that do not involve changes to base sequences in a gene, but that result nonetheless in changes to gene expression. It has long been known that changes in gene expression play an important role in the establishment of pain states. But it is not known whether a priming injury can induce lasting epigenetic marks which would result in an increase in both postoperative acute pain and the risk for chronic pain. Only by fully understanding these epigenetic mechanisms will we be able to offer better drugs for the treatment of pain, and to identify those at high risk of postoperative pain and postsurgical chronic pain. The purpose of this study is to determine whether severity of pain following surgical procedures, such as third molar surgery is related to baseline methylation status of the promoter region of IL-6 and TNF-α and changes in methylation status post surgery.
This is a randomized controlled trial to evaluate the clinical efficacy of combined electro-acupuncture and auricular acupuncture for persistent Iinsomnia in the adult population in Hong Kong.
This is a randomized controlled trial with 12 month sleep education as intervention, followed by a 12 month observational period, to study whether sleep education would improve glycemic control and cardiometabolic profile of sleep deprived type 2 diabetic patients and evaluate the neurohormonal changes associated with sleep education.
This study evaluates the effect of different induction courses in children and adolescents with newly diagnosed acute myeloid leukemia. In the first course patients are randomised to receive either standard anthracycline therapy with mitoxantrone or experimental DaunoXome. In the second course patients are randomised between standard treatment with ADxE (cytarabine, DaunoXome, etoposide) or experimental therapy with FLADx (fludarabine, cytarabine, DaunoXome).
