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.
Rotator cuff tears are one of the most common conditions encountered in orthopaedic practice leading to significant shoulder pain and functional deficit. The incidence of rotator cuff tears increases with age and previous trauma. Arthroscopic rotator cuff repair (ARCR) is a surgical procedure to reattach the torn edge of the tendon to the underlying bone, which can improve the clinical symptoms of patients. However, the retear rate after arthroscopic repair is as high as 94% (1). The high re-tear rate following cuff repair is due to the lack of a strong tendon to bone integration. The natural healing responses after surgical reattachment are too weak to regenerate strong tendon insertion, primarily owing to insufficient osteogenesis. To enhance the bone-tendon interface (BTI) healing, the investigators have developed a magnesium pin that can be applied to the cuff repair site to improve the BTI healing.This study is a single-center, randomized controlled trial to investigate the effect of using magnesium pin as a suture to augment rotator cuff repair. The intervention groups receives treated using magnesium pin additional to the suture anchor used routinely in clinical practice, whereas the control group receives routine suture anchor for the treatment-as-usual (TAU). The investigators hypothesize the magnesium pin applied in arthroscopic rotator cuff tears can promote BTI healing and reduce the cumulative retear rate with better functional outcomes.
Consequences of the compromised vascular system in diabetes mellitus (DM) are among the most devastating complications. Reduction in blood flow and oxygen uptake of skeletal muscle leads to muscle fatigue and impaired skeletal muscle post-exercise adaptation. Recent studies showed that intermittent vacuum therapy (IVT) augments the blood flow of the foot in people with DM. This pilot study investigates the effects of combined IVT and aerobic exercise in improving lower limb muscle oxygenation and distal circulation in individuals with DM. Positive results of the study shed light on strategy that enhances the effectiveness of aerobic exercise in people with DM.
About 80% of advanced ovarian cancer patients recurred in 2-3 years. Secondary cytoreduction benefits selected patients who have high chance of complete resection. Whether secondary interval surgery can be used at recurrence is not known.
A prospective, randomized controlled study was conducted from August, 2022 to March, 2023 in the neonatal intensive care unit in Queen Mary Hospital, Hong Kong. The aim of this study was to determine whether microdrops Mydrin-P demonstrates similar efficacy as standard Mydrin -P eyedrops applied to neonates undergoing retinopathy of prematurity (ROP) screening exams, also to ascertain the optimal time for eye examination after administration of mydriatics and assess whether the cardiovascular, respiratory and gastrointestinal adverse effects differ between microdrops and standard dose Mydrin-P. Preterm infants were randomized to receive either the standard Mydrin-P eyedrops or the mydriatic microdrops which contained around one-third of the standard Mydrin-P dosage. The primary outcome measured whether a successful ROP examination was conducted. Secondary outcomes included pupil diameters at baselines, 30 minutes, 60 minutes, 120 minutes after eyedrops instillation and at the time of ROP exam as well as adverse effects followed by the mydriatics administration. A total of 18 patients were enrolled in this study with total 46 episodes of ROP recorded. All episodes with microdrops instillation led to successful ROP exams. There was no statistically significant difference between standard eyedrops and microdrops in determining the success of ROP exam (p=0.233). Mean pupil diameter did not differ between the microdrops and standard eyedrops group. At the time of ROP exam, the mean pupil diameter was 5.47mm in the standard eyedrops group and 5.73mm in the microdrops group. The optimal time for ROP exam was 60 minutes to 120 minutes after first dose of mydriatic. Also there was no difference in the occurrence of systemic side effects when compared to standard Mydrin P drops. Hence the study concluded that microdrops have similar efficacy and safety profile compared to standard Mydrin-P eyedrops.
This is a prospective parallel group, double-blinded randomized controlled trial. Subjects are randomized into two groups - the intervention group and waitlist control group. Subjects received resistance, aerobic, flexibility and balance exercise training; and nutritional supplement containing β-hydroxy β-methylbutyrate (HMB). The intervention group would first receive the intervention during the 12-week study period. Meanwhile, the waitlist control group would receive 12 weeks of conventional care. After the study period, they would receive the same intervention.
The goal of this clinical trial is to determine the clinical effectiveness of a Chronic Care Model (CCM) named Risk Assessment and Management Program on Knee OA (RAMP-Knee OA) in adults with knee Osteoarthritis (Knee OA) at 52 weeks. Participants will be screened for eligibility to participate. After confirming eligibility, participants will complete the baseline assessment and be randomized into one of the following groups (n=114 for each group): 1. RAMP Knee-OA group 2. Usual care group Outcomes will be measured at baseline, week 16, week 32, and week 52.
The goal of this clinical trial is to compare pharmacological and non-pharmacological treatment effects on the children with different predicted myopia progression rate measured by modified multifocal electroretinogram. The main questions it aims to answer are: - the effectiveness of using 0.05% atropine and prescribing DIMS lens for myopia control in children with different myopia progression rates - the contribution of L/M cones in juvenile myopia progression and changes of retinal activities under atropine and DIMS treatment. Participants will have baseline and follow-up eye examinations and given either pharmacological treatment with 0.05% atropine or non-pharmacological treatment with DIMS lens for myopia control. Researchers will compare the changes of refractive errors and axial length after different types of interventions and investigate the relations between the parameters of mfERG responses and the thicknesses of retinal layers and choroid.
The goal of this waitlist control study is to evaluate the benefits of virtual reality teaching pedagogy to developing non-technical skills in nursing students. The main question[s] it aims to answer are: 1. What is the relationship between VR training programs and students' situation awareness skills development? 2. What is the relationship between VR training programs and students' communication skills development? 3. What is the relationship between VR training programs and students' satisfaction/self-confidence in learning? 4. What is the relationship between the sense of presence and satisfaction/ self-confidence in learning? 5. How does the student's learning experience after VR training programs? Participants will attend the Virtual Reality training program. Researchers will compare the use of high-fidelity simulation to see if the non-technical skills were developed.
Music has been proven to be beneficial in postoperative care by reducing pain. The effects of music listening to reduce pain postoperatively are well studied among cases undergoing elective orthopaedic surgery. No study has been conducted focusing on pain control among cases with fragility hip fractures in an acute ward setting with non-schedule non-elective orthopaedic operation. In Queen Elizabeth Hospital a standardized analgesic protocol is used for all fragility hip fracture cases unless contraindicated, a suboptimal post-operative pain control is not uncommonly seen. Stepping up analgesics is usually a concern in the elderly with a higher rate of side effects, a safe and simple non-pharmacological intervention for pain control is therefore needed. The aim of this study is to study the effectiveness of incorporating music on pain intensity and mobility with the standard postoperative rehabilitation care of fragility hip fracture in Queen Elizabeth Hospital.
This is a long term follow-up study for chronic hepatitis B (CHB) subjects who have received imdusiran treatment in a prior clinical trial, stopped NA therapy during that trial, and remain off therapy. Subjects may enroll after completing the end of study visit (baseline visit within 12 weeks ± 1 week from the end of study [EOS] visit) from their imdusiran clinical trial (the "parent study"). No interventions will be performed in this study other than blood sample collections, review of current medications, and reporting of any adverse events related to study procedures or NA therapy if restarted. Study participation will be for approximately 2 years (to complete a total of at least 3 years of follow-up while off NA therapy, inclusive of parent study participation).
