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.
As a major breakthrough of acute stroke treatment over the past decade, endovascular thrombectomy (EVT) drastically improved neurological recovery and survival in patients with large vessel occlusion (LVO) ischemic strokes in major clinical trials. Nevertheless, much remained uncertain about the implementation of scientific evidence of EVT into real-world benefits. For instance, healthcare policies that influence critical time-matrices, endovascular thrombectomy techniques that may enhance success rate or prevent complications, or advanced imaging techniques that allow precise prognosis or expansion of treatment populations, should be evaluated. On the other hand, capturing LVO patients who were not able to undergo EVT may reveal the gap between clinical trials and real-world practice in the Asia-Pacific. In this multicenter prospective collaboration across the Asian-Pacific, the investigators aim to evaluate the determinants of effective EVT in the real-world setting.
Horticultural therapy is one of the effective interventions for the person with dementia(PWD) which could increase their time engaging in leisure activities and decrease their time doing nothing. However, there are some limitations and constraints for PWD to participate in the horticultural therapy especially in the high-density cities (e.g. Hong Kong). This study aims to investigate the feasibility and preliminary effects of adopting home-based technology-enhanced horticultural activities. The program will consist of three face-to-face (F-T-F) horticultural activity training session for a group of 6-8 participants and then biweekly telephone follow-up for 8-week home-based horticultural intervention. Program evaluation will be conducted through focus groups with 15 participants with different levels of stress reduction after the intervention. It is hypothesized that the PWD and their caregiver will have a significant improvement in the cognitive function and behavioral symptoms of the PWD, an increase in the positive caregiving experience in the family caregivers, a reduction of the caregivers' level of stress and depressive symptoms, and enhancement of the quality of life of the family caregivers after the intervention.
Objectives: This study aims to explore the feasibility, acceptance, and efficacy of online group-based dual-task training as an intervention for improving cognitive function among community-dwelling older adults. Hypothesis to be tested: We hypothesize that after the intervention, there will be an improvement in the participants' cognitive function as compared with pre-intervention status and with the control group. Also, lower-limb muscle strength and psychosocial wellbeing will be improved after the intervention. Design and subjects: This is a randomised controlled feasibility study. The target population is community-dwelling older adults with access to an online meeting platform. About 75 participants will be recruited and randomised to the intervention and attention control groups in a ratio of 2:1. Intervention group will receive 60 minutes of online group-based dual-task training twice a week for 12 weeks led by a trained facilitator. Cognitive training components include arithmetic operation, verbal fluency, and upper limb/finger movement. Physical training components are chair-based exercises. The training components will be selected using a co-design approach. Instruments: Memory Inventory in Chinese (MIC), Digit Span Test, Victoria Stroop Test, Montreal Cognitive Assessment 5-Minutes (Hong Kong Version). Main outcome measures: Subjective memory complaints as measured by MIC.
The spontaneous passage rate for ureteral stone less than 1cm causing acute ureteral obstruction is about 50%. Previous Cochrane review has concluded that alpha blocker is likely to increase stone passage rate, reduce time to stone passage, analgesic use and hospitalisations. The European Association of Urology Guideline also recommends giving alpha blockers as Medical Expulsive Therapy to patients with distal ureteric stones >5mm. However there is heterogeneity in different alpha blockers. Silodosin is a recently introduced selective alpha blocker which has a much higher selectivity for the alpha-1-A receptor (17-fold compared with tamsulosin). From previous animal studies, ureteral contraction is mainly mediated by the alpha-1-A receptor, hence silodosin maybe more effective in increasing stone passage compared with tamsulosin. Previous studies and meta-analysis has shown superiority of silodosin over tamsulosin on earlier stone passage and less pain. However, there is no data on Chinese population. The investigators would like to compare the efficacy and side effect profile of Silodosin versus tamsulosin on improving stone passage rate and hence reduce rate of further intervention for stone clearance.
This is an open-label, Phase 2 study of bomedemstat (IMG-7289), an inhibitor of lysine-specific demethylase 1 (LSD1), in combination with JAK inhibition (JAKi) in patients with myelofibrosis.
This is an investigator-initiated, prospective, single-centre, non-randomized, all-comers registry that evaluates the safety and efficacy of any Paclitaxel Drug-Coated Balloon (DCB) for the treatment of coronary de novo lesion, in-stent restenosis, and small vessel disease in patients with coronary artery disease in Hong Kong. The recruitment time frame of this study is 1 year from 1st January 2022 to 30th December 2022.
Heart failure (HF) is one of the most important reasons for hospital admission and is associated with high mortality and morbidity. After discharge, up to 40% of patients are readmitted within 6 months and 1-year post-discharge mortality is high. The cost burden of treating patients with HF is high and ~80% of healthcare costs are related to hospital admissions. Sodium-glucose cotransporter-2 (SGLT2) inhibitor is considered one of the four foundational therapies (ACE-I or ARNI, beta-blockers, MRA, and SGLT2 inhibitors) for HFrEF. In particular, empagliflozin has been shown in randomized controlled trials to reduce the combined risk of cardiovascular death or HF hospitalization in HF patients with both reduced ejection fraction (HFrEF) and preserved ejection fraction (HFpEF). However, guidelines do not specify the sequence and the timing of which therapy to be commenced. The timing of SGLT inhibitors initiation in the treatment of acute HF is not established. In particular, new-onset acute HF is a group which is understudied in the major trials to date. This study aims to evaluate the efficacy and safety of in-hospital initiation of empagliflozin in patients hospitalized for new onset acute HF, regardless of LVEF for up to 90 days of follow-up.
Background Cardiac Resynchronization Therapy (CRT) is proven to improve survival and heart function of patient with certain electrical conduction abnormality and heart failure. However, in patient with certain electrical conduction abnormality, being nonresponder is observed in up to 40% in patient receiving CRT. Conventionally the surgical approach of CRT is to implant one pacing lead in the right heart and one in the left heart to resynchronize the contraction and the pacing lead in the left heart is usually placed in the posterior or lateral portion of the left heart. However, this single approach may not be optimal, especially for those patients with conduction abnormality known to have no response to CRT. Purpose of the clinical investigation The purpose of the Activation Pattern and Acute Hemodynamics of His and Left Bundle Pacing is to study the acute effect on the heart function and conduction abnormality of His and left bundle pacing in conventional CRT candidate. During CRT implantation, Hisbundle lead and Left bundle pacing lead will be placed and the acute effect on heart function will be studied by a wire placed in the left ventricle of the heart and the activation pattern will be studied by a noninvasive global mapping system. The pacing approach that optimally corrects conduction abnormality and improvement on the heart function acutely will be determined

The purpose of the Electrical Activation Guided CRT for Nonresponders Study is to study the effectiveness of an addition of Hisbundle pacing approach to CRT nonresponder by direct His-bundle pacing to improve the responder rate of nonresponder of conventional CRT and a tailored made approach to CRT procedure by using a noninvasive globally mapping system studying the electrical conduction under different approaches to delivery CRT. The pacing approach that optimally corrects conduction abnormality will be determined before the actual addition of new lead procedure. Conduct of the Investigation This study will include 18 patients already implanted with device delivering conventional CRT that known to have no response to the conventional CRT after 6 months of the CRT therapy from Prince of Wales Hospital, Hong Kong. You will be followed in the device clinic as per usual care after your participation in the study is completed.
Cardiac resynchronization therapy (CRT) is an established therapy for symptomatic heart failure patients. However, there are still 30 to 40% of studied patients being nonresponder to CRT. The plausible reasons of lack of effect of CRT in these patients include relative less baseline electrical dyssynchrony. The aim of our study is to investigate whether there is an optimal configuration of CRT delivery that varies between patients with different pattern of activation delay.
