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.
Using detailed serial cross-sectional estimates of the age-specific distribution of SARS-CoV-2 Omicron variant-specific antibody positivity levels, we derived age-specific infection attack rates and age-specific population immunity levels and tracked the magnitude of individual-level and population-level waning immunity over time. Our findings will inform health policy makers on devising future public health and social measures and vaccination guidance in response to the ongoing COVID-19 pandemic.
At present there is no cure for food allergy. People with a food allergy need to avoid the food they are allergic to in order to stay safe, but we know that accidental exposure is common. Researchers have begun to look at the effectiveness of 'oral immunotherapy' as a treatment for food allergy but results have been mixed. This study is a randomized controlled trial to evaluate the effectiveness of Fish Immunotherapy (FOIT), with codfish as the primary focus, in inducing tolerance in children with fish allergy compared with Placebo. Children will take increasing doses of codfish protein until a total of 12 months treatment is completed. Children will be tested for fish allergy at the start of the study, at the end of fish treatment T1 (12 months) and T2 (8 weeks) after treatment.
The primary objective of this study is to compare the effect of treatment with olpasiran, to placebo, on the risk for coronary heart disease death (CHD death), myocardial infarction, or urgent coronary revascularization in participants with atherosclerotic cardiovascular disease (ASCVD) and elevated Lipoprotein(a).
Meibomian gland dysfunction (MGD), closely associated with Dry Eye Disease (DED), is a chronic condition where terminal ducts are obstructed and/or glandular secretion changes. The efficacy of traditional treatment options, e.g. eyelid warm compress therapy (EW) is limited with low compliance. This study aims to (1)compare the efficacy and safety of two emerging alternatives- vectored thermal pulsation(VTP) or intense pulsed light and meibomian gland expression(IPL + MGX) with EW therapy; (2)identify factors predicting outcome. This is a prospective, randomized, assessor-masked, active-controlled clinical study. 360 participants (360 study eyes) with mild-to-moderate MGD will be randomized by minimization into three arms equally, receiving either VTP by TearScience-LipiFlow® Thermal Pulsation System (month 0), IPL by Lumenis®️M22 with MGX (month 0, 1, 2, 3) or EW (twice daily). Lubricating eye drops (3% Hypromellose) will be provided for all subjects throughout the study period(15 months). Tear film breakup time will be assessed as primary outcome at month 6, 15. Serial measurements of MG, tear-film, DED-related parameters, intraocular pressure, compliance to EW, factors associated with outcomes and treatment-related complications will be conducted at baseline and each follow-up visit by masked observers at baseline and eight follow-up evaluation (month 0, 1, 2, 3, 4, 6, 9, 12, 15).
This randomized Phase 3 open-label study will compare the efficacy of the T-cell immunoglobulin and immunoreceptor tyrosine-based inhibitory motif (ITIM) domain (TIGIT) monoclonal antibody domvanalimab, the anti programmed cell death protein 1 (PD-1) monoclonal antibody zimberelimab, and multiagent chemotherapy versus the anti PD-1 monoclonal antibody nivolumab and multiagent chemotherapy in the first-line treatment of participants with locally advanced unresectable or metastatic gastric, gastroesophageal junction (GEJ), and esophageal adenocarcinoma.
Spinal cord injury is a multi-sensory, motor and autonomic dysfunction, caused by various types of acute and chronic central nervous system injuries. And it will affect patient's ability to live normally and return to society. Due to lack of physical activity and psychological and environmental factors, the feces remain in the intestine for too long, and there will be excessive water absorption and lead to dryness and difficulty in excretion and it will be constipation. Chinese medicine, acupuncture and acupressure are the treatments of constipation in Traditional Chinese Medicine. Acupressure is a non- invasive intervention which is easy to learn and apply. We have carried out a number of studies on spinal cord injury rehabilitation support and acupressure to solve chronic problems such as constipation and anxiety. And this study aims to investigate the effects of acupressure combined with nursing intervention on constipation and quality of life in community-dwelling spinal cord injury patients.
In recovered COVID-19 patients, emerging global data have reported the presence of long COVID, that is, at least one symptom that an alternative diagnosis cannot explain has been persistent for four or more weeks after the initial infection. We demonstrated previously that almost 80% of recovered COVID-19 patients in Hong Kong suffer from Long COVID for more than 6 months, affecting multiple body systems. In a recent study, the five most common Long COVID symptoms were fatigue, memory problem, difficulty sleeping, anxiety and hair loss. One promising hypothesis is the involvement of the gut microbiota, a collection of the trillions of gut microorganisms that play important immunomodulatory roles against infections. Faecal microbiota transplantation (FMT), which is the infusion of processed faeces from healthy donors to the gut of affected subjects, has shown impressive therapeutic effects for recurrent Clostridioides difficile infection and other emerging indications. Gut microorganisms together with the metabolites in the donated faeces could potentially modulate the gut microbiota of the recipient and treat the dysbiosis associated with pathological health conditions. To date, no study has yet to assess the therapeutic effects of FMT in post-COVID-19 neuropsychiatric conditions.
A double-blinded, randomizepd controlled trial to investigate the treatment effects of pulsed electromagnetic field (PEMF) on end stage of knee osteoarthritis patients with sarcopenia will be carried out. Subjects will be recruited from the Prince of Wales Hospital. Sixty participants age ≥ 60 will be invited to join this trial after informed consent. They will be randomised to any of the 2 groups: intervention group (n=30; PEMF (Quantum Tx) treatment), and control group (n=30; sham treatment with dummy exposure to PEMF). Both group will receive home-based exercise. Baseline measurements include appendicular muscle mass by DXA, bone microarchitecture (XtremeCT II), knee flexion and extension strength by handheld dynamometer, knee flexion and extension range of motion by goniometer, self-reported knee pain (VAS) and function by The Knee Injury and Osteoarthritis Outcome Score (KOOS), International Physical Activity Questionnaire (IPAQ) for assessment of physical activity level, quality of life by SF-36, hand grip test, bioelectrical impedance analysis （BIA）of body composition, postural stability, chair stand test, 30s arm curl test and 6-meter walking test. These measurements will be performed again at middle and end of treatment, 3, 6, and 12 months after commencement of treatment, except DXA, which will not be performed at the midpoint. In addition, blood samples will be taken at baseline, middle, and end of treatment, 3, 6, and 12 months after commencement of treatment, for determing of serum myokines which are reported to be sensitive to PEMF treatment and contribute to myogenesis. The aim of this study is to conduct a double-blinded, randomized controlled trial to investigate the effects of PEMF treatment on muscle gain and pain relief in knee osteoarthritis with sarcopenia elderly in Hong Kong. We hypothesize that PEMF treatment is effective to promote a gain in muscle mass and function and pain relief in knee osteoarthritis with sarcopenia elderlies.
Surgical coronary bypass surgery (CABG) has been demonstrated to confer significant survival benefit over medical therapies patients with LMCA in earlier clinical trials1,2,3 and therefore was the revascularization modality of choice for a long time. Recently, several randomized controlled trials and meta-analyses have shown percutaneous coronary intervention (PCI) to be non-inferior to CABG in the treatment of LMCA disease4,5,6,7,8. PCI is now considered to be an appropriate alternative to CABG for LMCA disease in patients with suitable anatomy9,10. Over recent decades, LMCA PCI has been performed in patients with increasing anatomical complexity and higher risk profiles (e.g. elderly, heart failure, renal failure etc). 11,12. In recent years, remarkable advancement in interventional techniques and technologies such as 2nd/3rd generation DES and potent antiplatelet therapy have contributed to the improvement of PCI success rates and reduction in complications and adverse events. Knowledge related to long term temporal variation of clinical and procedural characteristics and outcomes in patients with LMCA disease treated with PCI will therefore be important to inform and define future treatment strategies. This proposal aims to evaluate time-trends and regional differences in clinical characteristics and outcomes of patients with LMCA disease treated with PCI in the Asia-Pacific region
Background: Communication of information about risk of type 2 diabetes (T2D) alone has not been associated with changes in habitual behaviors among individuals of European ancestry. In contrast, the use of wearable devices that monitor physical activity (PA) has been associated with changes in behavior in some studies. It is uncertain whether risk communication might enhance the effects of wearable devices. We aim to assess the effects on wearable-device-measured PA of communicating genetic risk for T2D alone or in combination with goal setting and activity prompts from a wearable device among overweight or obese East Asians. Methods: In a parallel group, randomized controlled trial, a total of 355 overweight or obese East Asian individuals aged 40-60 years will be allocated into one of three groups: 1 control and 2 intervention groups. Blood samples will be used for estimation of T2D genetic risk and analysis of metabolic risk markers. Genetic risk of T2D will be estimated based on 113 SNPs associated with T2D among East Asians using an established method. All three groups will receive a Fitbit device. Both intervention groups will be given T2D genetic risk estimates along with lifestyle advice, but one of the intervention groups will additionally use Fitbit's step-goal setting and prompt functions. Questionnaires and physical measurements will be administered at baseline, immediately after intervention delivery, and 6 and 12-month post-intervention following standard operating procedures. The primary outcome is time spent in moderate-to-vigorous PA measured through the Fitbit. Secondary outcomes include other parameters of wearable-device-measured PA, sedentary time, and sleep, body mass index, systolic and diastolic blood pressure, five intermediate metabolic risk markers, hand grip strength, self-reported PA, self-reported fruit and vegetable consumption and smoking status, and a list of psychological variables. Discussion: This study will be the first randomized controlled trial using the combination of communication of T2D genetic risk with standard functions of wearable devices in any population. Findings will inform strategies to prevent T2D through lifestyle modification.
