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.
Objectives: Obstructive sleep apnoea (OSA) exhibits variable susceptibility to end-organ morbidities. Previous studies suggest that physiological sequelae in individuals with OSA promote changes in microbiome, which also interact with metabolic and inflammatory mediators. Therefore, microbiome and metabolomic profiling could potentially reveal the pathological processes underlying OSA. The primary objectives of our study are 1)To investigate the differences in the composition of nasal and stool microbiome between children with OSA and non-OSA controls; 2)To investigate the differences in the urine metabolomic profiles between children with OSA and non-OSA controls. Hypothesis to be tested: The microbiome composition and urine metabolomic profiles are different between children with OSA and non-OSA controls. Changes in microbiome composition are associated with specific urine metabolomic and inflammatory profiles in children with OSA. Design and subjects: A prospective case-control study. Chinese children aged 6-11 years old with habitual snoring and polysomnography (PSG) confirmed OSA will be recruited as cases. Non-OSA healthy children will be recruited as controls. All subjects will undergo evaluation including questionnaires, anthropometric measurements, PSG, blood, urine, nasal and stool sampling. Primary outcome measures: Microbiome and metabolomic profiles in children with OSA compared to non-OSA controls. Analysis: Comparisons of the microbiome and metabolomic profiles between OSA children and controls. Correlations of microbiome and metabolomic profiles with inflammatory biomarkers and PSG measurements will be evaluated by regression analysis. Expected results: This study will provide novel data regarding microbiome and metabolomic profiles, and their relationship with inflammatory biomarkers in children with OSA.
Objectives: Variability of clinical phenotypes in childhood obstructive sleep apnoea (OSA) has prompted research for biomarkers to identify patients at risk of developing OSA-related complications. Upper airway inflammation is documented in children with OSA. Whether it is related to end-organ morbidities and systemic inflammation is under-explored. The primary objectives of our study are 1)To evaluate inflammatory biomarkers with the use of nasal epithelial lining fluid (NELF) collected by nasal strips as a representation of upper airway inflammation in children with OSA compared to non-OSA controls; 2) To evaluate the associations between NELF biomarkers with ambulatory blood pressure (ABP) outcomes in children with OSA. Hypothesis to be tested: Inflammatory biomarkers in NELF in children with OSA are altered when compared with non-OSA controls and correlated with ABP outcomes. Design and subjects: A prospective case-control study. Non-obese Chinese children aged 6-11 years old with habitual snoring (≥3 nights per week) and polysomnography (PSG) confirmed OSA (OAHI of ≥1/hour) will be recruited as cases. Non-OSA children with OAHI < 1 event/h will be recruited as controls. All subjects will undergo evaluation including questionnaires, anthropometric measurements, PSG, 24-hour ABP measurement, blood and NELF sampling. Primary outcome measure: Profile of inflammatory biomarkers in the NELF. Analysis: Correlations between NELF inflammatory biomarkers with polysomnographic and ABP measurements will be evaluated by regression analysis. Expected results: This study will provide novel and important information regarding upper airway inflammatory biomarkers in children with OSA and their relationship with blood pressure outcomes.
Researchers are looking for a better way to treat people who have advanced non-small cell lung cancer (NSCLC) with specific genetic changes called human epidermal growth factor receptor 2 (HER2) mutations. Advanced NSCLC is a group of lung cancers that have spread to nearby tissues or to other parts of the body or that are unlikely to be cured or controlled with currently available treatments. HER2 is a protein that helps cells to grow and divide. A damage (also called mutation) to the building plans (genes) for this protein in cancer cells leads to a production of abnormal HER2 and therefore abnormal cell growth and division. The study treatment, BAY 2927088, is expected to block the mutated HER2 protein which may stop the spread of NSCLC. The main purpose of this study is to learn how well BAY 2927088 works and how safe it is compared with standard treatment, in participants who have advanced NSCLC with specific genetic changes called HER2 mutations. The study participants will receive one of the study treatments: - BAY 2927088 twice every day as a tablet by mouth, or - Standard treatment in cycles of 21 days via infusion ("drip") into the vein. The treatment will continue for as long as participants benefit from it without any severe side effects or until they or their doctor decide to stop the treatment. During the study, the doctors and their study team will: - take imaging scans, including CT, PET, MRI, and X-rays, of different parts of the body to study the spread of cancer - check the overall health of the participants by performing tests such as blood and urine tests, and checking - heart health using an electrocardiogram (ECG) - perform pregnancy tests for women - ask the participants questions about how they are feeling and what adverse events they are having. An adverse event is any medical problem that a participant has during a study. Doctors keep track of all adverse events, irrespective if they think it is related or not to the study treatment.
The goal of this clinical trial is to test the effectiveness of brief behavioural economic intervention in promoting smoking cessation among smokers in the community.
The goal of this clinical trial is to examine the effectiveness of a Virtual Reality (VR) social avoidance intervention in reducing social avoidance symptoms among adolescents with special educational needs. Participants will complete tasks in the VR scenario with increasing difficulty and learn that they can cope in situations that they previously avoid. We hypothesize that, comparing with usual care (i.e. waitlist control), the intervention group will experience a significant reduction on social avoidance symptoms after treatment and this benefit will persist till 1-month follow-up.
The goal of this pre-post study is to enhance the health and wellness of the residents in the Concordia Tsat Sing Kong Transitional Housing Estate. This study aims to evaluate the effectiveness of the Green Oasis (GO) wellness program in: 1. Increase health awareness and engaging in health promoting activities, including more physical activities/walking, gardening. 2. Enhance happiness and quality of life. Participants will: - complete physical exercises, gardening, and interact with the GO website - receive health talks
The goal of this study is to evaluate the feasibility, acceptability, safety and preliminary efficacy of a chatbot-based mindfulness-based stress reduction (MBSR) intervention for university students with depressive symptoms. A rule-based MBSR chatbot will be developed and evaluated with a single-group pretest-posttest study for university students aged 18 or above in Hong Kong reporting depressive symptoms, followed by the collection of their subjective feedback. The intervention will last eight weeks. The primary clinical outcome is depression levels, with a range of secondary outcomes including stress, anxiety and mindfulness levels.
This prospective, randomised, double-blinded cross-over study aims to compare the effectiveness of auricular acupuncture (AA) with placebo sham acupuncture (PSA) in reducing dental anxiety, pain perception and physiological responses to stress and anxiety among adolescents during orthodontic extractions. Adolescents aged between 10-19 years old who are undergoing orthodontic treatments requiring bilateral premolar extractions will be invited to complete a validated questionnaire to record their dental anxiety level, oral health knowledge, attitudes, practices, demographic and socio-economic factors. During orthodontic extractions, physiological responses including heart rate and oxygen saturation will be measured with a fingertip pulse oximeter throughout the process. The participants will be allocated randomly to one of the two groups in the study. Group 1-- auricular acupuncture in their first orthodontic extraction visit and placebo sham acupuncture in their second orthodontic extraction visit. Group 2-placebo sham acupuncture in their first orthodontic extraction visit and auricular acupuncture their second orthodontic extraction visit. Both acupuncture interventions will be carried out by a Hong Kong registered Chinese medical practitioner. The acupuncture needles are kept in place for 20 minutes to exert its effect before the dental extraction. Placebo sham acupuncture will not cause any harm, but the acupuncture points have no reported effect on stress relief. The extraction of premolars will be performed by a Hong Kong registered dentist. Local anesthesia is injected to numb the respective site, then the premolar will be removed with forceps, followed by stopping the bleeding by biting firmly on gauze.
The goal of this waitlist control study is to evaluate the benefits of online game pedagogy to evaluate the readiness of health care students for interprofessional learning in nursing students. Interprofessional (IP) collaboration is a core competence of health care education to enable effective teamwork and improve health outcomes. Taking into account the characteristics of our students and the pragmatic issues, v-Care (Virtual Care) is a novel strategy to deliver Interprofessional Education using gamification. Colleagues from nursing (SN), rehabilitation sciences (RS) and health technology and informatics (HTI) will collaborate in the design of v-Care, and implement and evaluate it effectiveness in nursing, physiotherapy and radiography related subjects. To evaluate the effectiveness of interprofessional learning of the health faculty students using a multi-player point-and-click on line motivational game. Theoretical Framework The v-Care design is based on the Self-Determination Theory (SDT) and Motivational Gamification. Outcomes: The primary outcome is to improve the readiness for interprofessional learning. A peer learning community will be established to improve the motivation to learn based on SDT: (1) autonomy, (2) competence and (3) relatedness.
HCC is a huge healthcare burden in Hong Kong and is one of the top 5 cancers in terms of incidence and mortality in Hong Kong. Patients with advanced HCC are treated with immunotherapy-based combination atezolizumab plus bevacizumab as first-line treatment as a standard of care. At the moment, there is limited evidence to guide subsequent treatments after patients progressed on atezolizumab plus bevacizumab. Oligoprogression is a term used to describe patients who had limited progression (usually less than 3 sites) on systemic therapy, with the rest of the lesions controlled. Previous studies in non-HCCs have shown that addition of locoregional treatment (e.g. radiotherapy) may prolong the use of systemic therapy, resulting in improved survival, but this has been relatively unexplored for HCC. In this prospective, single-arm study, we aim to evaluate the treatment outcome, efficacy and safety of the addition of radiotherapy to oligoprogressive sites for patients who had limited progression on atezolizumab plus bevacizumab.
