There are about 3715 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.
There have been previous reports of using High-intensity focused ultrasound (HIFU) as a feasible thermal ablative treatment for relapsed Graves' disease. In recent years, radiofrequency ablation (RFA) has become another promising alternative for thermal ablation of benign thyroid nodules. RFA has the advantage of avoiding a surgical scar, organ preservation and being an ambulatory procedure. It utilizes a small caliber radiofrequency electrode, which is inserted into the thyroid gland percutaneously. The active tip of the RF electrode would induce frictional heat in the surrounding tissue, causing a thermal ablative effect. The direct application of energy of RFA to tissue is different from that in HIFU, in which energy is transmitted through the skin of the patient from the transducer. To our knowledge, studies of follow-up after RFA of Graves' disease have not been published. Given the previous successful experience with HIFU, we would like to explore the feasibility, safety and efficacy of RFA as an alternative thermal ablation option for relapsed Graves' disease. Thus, the purpose of this prospective study is to assess the efficacy and safety of US-guided RFA for the treatment of relapsed Graves' disease.
This study aims to examine the effectiveness of a 12-week home-based telerehabilitation programme on improving subjective well-being among community-dwelling older people with frailty. The main question it aims to answer is - Could home-based psychoeducation significantly enhance subjective well-being in older adults with frailty in the community? Participants will receive 12 weekly online group-based sessions at their homes. The content for the experimental group and control group is different: - Intervention group: psychoeducation - Control group: physical health education Participants will receive three home visits for data collection. Some of participants in experimental group will receive interview for process evaluation.
It is a single-center, prospective study, which will be conducted in a tertiary academic hospital (Prince of Wales Hospital). All subjects will undergo a paired examination of HemoPill® acute capsule and oesophago-gastro-duodenoscopy (OGD).
The current study is a pilot for the GRF project entitled "Predicting illness trajectories in fully remitted major depression using concurrent TBS/fNIRS". The project aims to determine whether immediate prefrontal excitability modulated by intermittent theta-burst stimulation (iTBS) is altered in remitted major depressive disorder (rMDD) and therefore classifies as a potential trait marker to predict the incidence of recurrence. In the present cross-sectional study, we will recruit four clusters of population, including patients diagnosed with rMDD, currently depressed patients with varying numbers of episodes, healthy subjects, and never-depressed healthy subjects with elevated risk for MDD (defined as having a first-degree relative with a history of depression), to investigate the relationship between the number of prior episodes, cognitive function, and TBS-induced instantaneous brain activity change in the presumed neuropathological prefrontal cortex (PFC).
The objective of the study is to establish the safety profile of the autologous engineered osteochondral tissues (eOCT) in treating traumatic chondral lesions in patients.
The United States Food and Drug Administration (FDA) approved intermittent theta-burst stimulation (iTBS) in 2018 as a form of repetitive transcranial magnetic stimulation (rTMS). Hospitals worldwide use it to treat major depressive disorder (MDD). It is safe, effective, even for depressed patients unable to respond to standard pharmacological treatment and is more efficient than standard rTMS. In accordance with the approved treatment protocol, patients experience considerable sensory discomfort at a stimulation intensity of 120% of their resting motor threshold (rMT). Antidepressant effects of iTBS are believed to be mediated by modulating prefrontal excitability. There is still a lack of evidence to support the choice of 120% rMT as the optimal stimulation intensity, and the presumed superiority of higher stimulation intensities over lower intensities has yet to be proven. This knowledge gap has clinical implications since more tolerated treatments may lead to greater adherence, resulting in improved outcomes. The current study proposes a randomized, triple-arm, controlled trial to compare the efficacy of iTBS at 75% (iTBS75) and 120% (iTBS120) rMT with sham iTBS (SiTBS). Based on the following considerations, SiTBS was selected to be compared with iTBS75 and iTBS120: SiTBS will reveal placebo antidepressant effects and serve as a control. iTBS75 is selected because iTBS at 80% aMT exhibits significant excitatory effects on the motor cortex and corresponds to approximately 70% rMT. There is however, a distance of about 12.7mm between the coil and the motor cortex, whereas 14.4mm separates the coil from the dorsolateral prefrontal cortex (DLPFC). Accordingly, a resting motor threshold of 70% at the motor cortex corresponds to a distance-adjusted rMT of 75% at the DLPFC. Lastly, iTBS120 is chosen as the standard stimulation intensity in current iTBS depression trials. It is our intention to investigate the potential antidepressant effects of iTBS treatment at a much lower stimulation intensity than the one currently employed by most centers in the United States and approved in these centers. Thus, our study can contribute to establishing a treatment regimen with increased adherence and lower withdrawal rates.
This is a multicenter, multiple expansion cohort, Phase 1 study to evaluate the safety, tolerability, pharmacokinetics, pharmacodynamics, and anti-tumor activity of DR-0201 in adult patients with relapsed or refractory B-cell non-Hodgkin lymphoma.
Pain Management in Older Adults: Pain significantly impacts the well-being of older adults, often leading to diminished physical abilities and a reduced quality of life. Despite this, pain management remains suboptimal, with concerns about medication side effects and a tendency to view pain as a natural aspect of aging. Consequently, many seniors are hesitant to use painkillers. As an alternative, non-pharmacological strategies such as educational programs, physical activity, massage, relaxation techniques, and music therapy are gaining traction. Innovative Non-Drug Solutions: To improve participation in non-medication pain relief methods, we suggest incorporating gaming elements into these programs (GAP). Originating in digital media in 2008, gamification has since spread across various industries. It involves adding game-like elements to activities to boost engagement, experience, and motivation. Project Goals: The aims of this initiative include creating a web-based Gamified Pain Management Program (GAP), engaging older adults with chronic pain in the development of GAP, and gathering their feedback on the program's effectiveness.
The treatment for fistula-in-ano (FIA) remains a challenge to General and Colorectal Surgeons Worldwide. A variety of surgical treatments have been described for high anal fistulas, but none offers the panacea of fistula eradication with guaranteed preservation of continence. This study compares Collagen paste injection to mucosal advancement flap for the treatment of fistula-in-ano.
The proposed study aims to investigate the efficacy of the Dynamic Temporal and Tactile Cueing treatment in Cantonese-English bilingual speakers with childhood apraxia of speech.
