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.
This study will examine the effects of smartphone-based lifestyle medicine (LM) for alleviating depressive and anxiety symptoms in Chinese population. Since a range of lifestyle factors are involved in the pathogenesis and progression of depression and anxiety, modifying different lifestyle factors simultaneously, for example, diet, exercise, stress and sleep which are empirically supported by previous reviews, may be effective to reduce depressive and anxiety symptoms. Traditional Chinese medicine concepts will be integrated into the app to increase the acceptability towards mental health treatment. Through this study, we aim to promote evidence-based patient care and to improve help-seeking and access to evidence-based interventions for depression and anxiety.
Diagnosis and treatment of small bowel pathologies remain challenging due to the long length of the small bowel. Obscure gastrointestinal (GI) bleeding with negative upper and lower GI workup, suspected inflammatory bowel disease, and suspected tumors of the small bowel often require small bowel investigation. While video capsule endoscopy (VCE) and computed tomography (CT) enteroclysis (CTE) are often the initial diagnostic modalities for suspected small bowel pathologies and can provide structural information of the small bowel mucosa, biopsy or therapy for the detected pathology could not be performed with VCE or CTE. In patients who require biopsy or therapy of the detected small bowel pathology, deep enteroscopy would be the procedure of choice in modern clinical practice before subjecting patient to surgery. Diagnostic and therapeutic deep enteroscopy can be performed by balloon overtube assisted enteroscopy (eg, double balloon enteroscopy (DBE), single balloon enteroscopy (SBE) or spiral overtube assisted enteroscopy (SE). Despite the difference in equipment design of DBE, SBE, and SE, the concepts for small bowel intubation by pleating the intestine over the endoscope are the same behind these techniques. Depending on the location of the small bowel pathology reported by VCE or CTE, antegrade (oral route), retrograde (anal route), or combined antegrade and retrograde deep enteroscopy for total enteroscopy can be performed.
Objectives: (1) To examine the upper trapezius muscle stiffness using SSI in workers with and without neck/shoulder disorders; and (2) to develop a workplace-based exercise programme to reduce upper trapezius muscle stiffness and to enhance shoulder function and work ability in the working population. Hypotheses to be tested: (1) Workers with neck/shoulder disorders demonstrate increase upper trapezius muscle stiffness when compared to healthy control; and a cutoff value of the upper trapezius stiffness was established for early identification of individuals at risk of having neck/shoulder disorders in the working population; (2) Workplace-based exercise programme can reduce upper trapezius muscle stiffness and enhance shoulder function and work ability in the working population. Design: Part A study: Cross-sectional study; Part B study: randomized controlled trial Subjects: One-hundred office computer workers with or without neck/shoulder pain Study instruments: Supersonic shear wave imaging Main outcome measures: Upper trapezius muscle stiffness, Shoulder Pain and Disability Index (SPADI), Neck Disability Index, Disability of the Arm, Shoulder and Hand (DASH), work ability index (WAI). Data analysis: Between-group comparisons to show differences in the outcome measures will be analyzed using Independent t-test. To compare the treatment effects, repeated-measures analysis of variance test (between-group factor: intervention vs control; within-subject factor: time (baseline, 6 week and 1 year)). Expected results: Workers with neck/shoulder disorders demonstrate increase upper trapezius muscle stiffness when compared to healthy control. Workplace-based exercise programme can reduce upper trapezius muscle stiffness and enhance shoulder function and work ability in the working population.
Liver transplantation is the best treatment option for patients with end-stage liver disease and early unresectable hepatocellular carcinoma. Unfortunately, biliary complication after liver transplantation is still the Achilles' heel, especially in living donor liver transplantation. Early treatment with endoscopy can achieve satisfactory outcomes. Most of the time, biliary anastomotic stricture can be treated by endoscopic retrograde cholangiopancreatography with balloon dilatation with or without plastic stent insertion. Although endoscopic treatment has been reported to have a successful rate of over 70%, multiple sessions of endoscopic treatment, typically 4 to 5 sessions, are frequently required before adequate stricture dilatation is achieved. This is likely secondary to suboptimal post-dilatation splintage. The most common and popular form of splintage is plastic stent insertion. Unfortunately, plastic biliary stent has a small calibre, and therefore even with multiple stents the configuration of buttressing would not provide a circumferential, evenly distributed buttressing effect at the dilated stricture site. Moreover, given the small calibre of the plastic stent, there is higher resistance on the inner surface of the stent, leading to a higher chance of stent blockage. Many studies have suggested that self-expandable metallic stent (SEMS) is superior to plastic stent in terms of patency rate. However, SEMS is generally reserved for malignant stricture due to its permanent nature, as the traditional SEMS is not removable. Recently, retrievable SEMS (r-SEMS) has been developed, and its indications have been extended to include benign disease conditions. It has been reported that a series of 29 patients with biliary anastomotic stricture treated by r-SEMS, and they concluded that r-SEMS was safe and efficacious. Results of the preliminary study on 5 patients at our centre were favourable; all of the patients had no stricture after retrievable metallic stenting for at least 3 months and no complication was encountered.
The proposed trial aims to test the feasibility of ecological momentary intervention on stroke caregivers' psychological distress.
To compare the safety and clinical efficacy (death, overall hospitalization, hospitalization for influenza or pneumonia) of ID QIV delivered via an intradermal device with imiquimod cream pretreatment with conventional intramuscular (IM) standard dose QIV and IM high-dose TIV
The scarcity of deceased donor organ supply has driven the practice of living donor liver transplantation (LDLT). Right lobe LDLT (RLDLT) has developed over the last 10 years to extend the benefit of LDLT to adult patients. With technical refinement, the results have significantly improved but bile duct complications remain the Achilles heel that affects the recipient's long-term outcome.Hepaticojejunostomy (HJ) was originally the standard technique for bile duct reconstruction in RLDLT but in recent years, duct-to-duct anastomosis (DDA) has been adopted by most transplant centers. The advantages of duct-to-duct reconstruction include a shorter operation time, less infection complications, more physiologic enteric functions and easier endoscopic access to the biliary tract but bile duct complication, particularly stricture is the major concern. The development of stricture is likely to be related to the blood supply of the anastomosis. We hypothesize that HJ has a better blood supply and is associated with a lower overall bile duct complication rate than duct-to-duct anastomosis. We propose a randomized trial to test this hypothesis and to compare various outcome measures between HJ and duct-to-duct reconstruction. The results of the study will set the standard for the technique of biliary reconstruction in RLDLT and will further advance this procedure.
This is a prospective clinical trial with each patient serving as his/her own control. Patients will be recruited in three different Hong Kong hospital. All patients at the recruitment centers with ongoing air leak after ≥ 3 days from the initial diagnosis of SSP will be approached by site investigators. Patient consented to enter the study will have their rate of air leak measured on day 3 (or after if enrolled later than day 3) byreplacing the conventional chest drain system with the digital chest drainage device (Thopaz). Autologous blood patch will be instilled if the patient still has persistent air leak on day 5 of chest drain insertion ( or 48 hours of electronic chest drain measurement of airleak).
Patients with severe COPD will be recruited from the Respiratory Outpatient Clinic of Kowloon Hospital. Baseline (pre-intervention) assessment for all recruited subjects will be conducted by one physiotherapist assessor who is blinded to the group allocation of the subject for respiratory function, musculoskeletal performance, physical performance and quality of life. Then, the subjects will be randomly allocated into either the intervention group with therapist-assisted chest wall mobilization exercises, low intensity walking exercise, home exercises and education sessions or the control group with low intensity walking exercise, home exercises and education sessions. The intervention program will last for 6 weeks with 2 sessions / week (i.e. a total of 12 sessions) in accordance to the recommendation for exercise training programs for patients with COPD by the American College of Sports Medicine. Post-program evaluation will be conducted upon program completion at 6 week. A follow-up session on 3 month after the completion of the program will be carried out to evaluate the cumulative effect of the chest wall mobilization program on respiratory function, musculoskeletal performance, exercise performance and quality of life of the patients.
Liver transplantation (LT) is a life-saving procedure for patients with end-stage liver diseases. Although with continuous advancement in technology, it remains a high-risk operation. The goal of LT is not only ensure survival of the patients but also to restore them back to their pre-morbid state with a good quality of life. Neurological sequelae can have major impact on postoperative outcomes after LT and yet the reported literature is scarce. Studies from Western countries showed some evidence on the use of cerebral oximtery in cardiac surgery to prevent neurological mishaps. LT shares similar intra-operative fluctuation of the haemodynamices as in cardiac surgery, causing disturbances in regional cerebral oxygenation and theorectically cerebral oximetry should be of great value as well in LT surgery. Data from a large randomised controlled trial is lacking from the current literatures. We therefore propose a prospective randomized controlled trial on the use of this device in adult LT and see whether its use could reduce neurological mishaps.
