This is a single-arm, open label, Phase II study of 12-week use of Roflumilast in stable-state non-cystic fibrosis bronchiectasis subjects. Bronchiectasis refers to a suppurative lung condition characterized by pathological dilatation of bronchi. The predominant aetiology of bronchiectasis in the Western population is related to cystic fibrosis (CF), which is genetically determined. Bronchiectasis due to other causes are generally grouped under the term "non-CF bronchiectasis", which accounts for practically all cases that are seen commonly in Hong Kong and many other Chinese populations. The main pathogenesis of non-CF bronchiectasis involves airway inflammation, abnormal mucus clearance and bacterial colonization, resulting in progressive airway destruction and distortion. This destructive process perpetuates in a vicious circle even when the initial insult has subsided, which is commonly due to an infective process like tuberculosis in Hong Kong. Patients with extensive bronchiectasis present with chronic cough, copious purulent sputum, haemoptysis, progressive lung function loss, and episodes of infective exacerbations. The current treatment strategies mainly focus on targeting the key elements in the pathogenesis of non-CF bronchiectasis. Apart from regular chest physiotherapy and postural drainage to help clearing mucus from bronchiectatic airways, inhalational and parenteral antibiotics have also been used to reduce the bacterial load in destroyed airways, thus controlling and preventing infective exacerbations. In recent years, accumulated evidence has suggested a central role of airway inflammation and immune dysregulation in the evolution of non-CF bronchiectasis. Chronic obstructive pulmonary disease (COPD) is a progressive destructive process on exposure to noxious environmental agents (e.g. tobacco smoke) that affects both the airways (chronic bronchitis) and lung parenchyma (emphysema), leading to loss of lung function and exercise capacity. Both COPD and bronchiectasis share similarities in clinical presentation and pathogenetic mechanisms. Neutrophilic inflammation and bacterial colonization are also the cornerstone in the airways of patients with COPD. Roflumilast, a phosphodiesterase 4 (PDE4) inhibitor, has demonstrated anti-inflammatory activity in COPD resulting in reduction in exacerbation frequency. This is the first-in-class and the only one clinically available PDE4 inhibitor that is approved worldwide (including Hong Kong) for treatment of severe COPD with frequent exacerbations. At the time of writing, the exact role and clinical evidence for roflumilast in dampening airway inflammation in non-CF bronchiectasis is still lacking. Given the common pathogenetic mechanism via neutrophilic inflammation between non-CF bronchiectasis and COPD, as well as the robust clinical activity of roflumilast in COPD, this study is designed to provide initial scientific evidence on the activity of roflumilast on neutrophilic airway inflammation in patients with stable-state non-CF bronchiectasis. This study aims to investigate the effect of 12-week treatment with roflumilast on neutrophilic airway inflammation in stable-state non-CF bronchiectasis.
The study focusses on utilizing neuroimaging modalities, including Electroencephalography (EEG) and Functional Magnetic Resonance Imaging (fMRI) to study the impact of non-invasive brain stimulation on the prefrontal cortex during a cognitive task.
This is an assessor-blinded, randomized controlled trial. A total of 248 elderly people aged ≥65 years with a mid-mild to moderate dementia will be recruited from local nursing and care homes. They will be randomly assigned to routine care, CAT, CAE, and CAT+CAE with n = 62 subjects each group. Subjects assigned to CAT, CAE, and CAT+CAE will respectively receive 2 sessions of CAT, 3 sessions of CAE, and a combination of both per week for 12 weeks. The primary outcome is baseline-to-endpoint change in score of the Montreal Cognitive Assessment (MoCA). Secondary outcomes include various domains of MoCA, functional independence, psychological well-being; sleep quality, and level of pain. A generalized linear mixed-effect model will be used to compare outcomes over time among the four groups.
Healthy eating is a key preventive approach to combat the rising prevalence of non-communicable diseases (NCD) worldwide. The dietary habit established during adolescence has high tendency to continue to adulthood, and is affected by family factors in multiple dimensions. Kerry Group Kuok Foundation (Hong Kong) Limited (KGKF) initiated the Trekkers Family Enhancement Scheme (TFES) in 2012 to empower low-income families in Tung Chung to self-care and development. In response to the persistent unhealthy eating habits among these families despite a series of nutrition workshops incorporating short talks and sharing of healthy recipes, this study aims to investigate the barriers, facilitators and strategies that enable adolescents from low income families to develop a healthy eating habit. Qualitative family interviews of 20 family units, or more until data saturation, of at least one parent and one adolescent (aged 10-19 year old) will be conducted based on deductive thematic approach. Each interview will last for about an hour, be conducted in Cantonese, and audio-taped for transcription in verbatim in Chinese. The data will be coded independently into broad themes in English by two members of the research team. This research can provide an insight into personal and familial factors and potential strategies influencing eating habits of adolescents, which can guide the development of effective interventions to promote healthy eating in low-income families.
This study will examine the effects of a smartphone-based lifestyle medicine (LM) for improving psychological well-being in Chinese population. Since a range of lifestyle factors are involved in the pathogenesis and progression of common mental disorders (e.g., depression and anxiety), modifying different lifestyle factors simultaneously may be effective to improve our psychological well-being. Chinese dietary recommendations will be integrated into the app to increase the acceptability towards mental health intervention. Through this study, we aim to promote evidence-based patient care and to improve help-seeking and access to evidence-based interventions for improving psychological well-being.
This is a pilot study to investigate the usefulness of closure of mucosal defect after gastric endoscopic submucosal dissection (ESD) in patients that are at high risk of post-procedural haemorrhage. Delayed haemorrhage is still an important adverse event of ESD, occurring more frequently for gastric lesions. Risk factors identified for delayed haemorrhage include chronic kidney disease, use of antithrombotic agent, lesion size >20mm, specimen size >30mm. Current established methods to prevent this complications could not completely eliminate the chance of bleeding, especially among high-risk cases. Closure of ESD defect may prevent ongoing exposure of submucosal vessels to gastric acid, and further reduce the risk of delayed haemorrhage. The investigators conduct this study to investigate the effect of closing the defect with endoscopic clips and loop. 30 patients who are undergoing gastric ESD deemed high risk of delayed haemorrhage would be recruited, with closure of defect after resection. The rate of delayed haemorrhage would be compared with historical cohort of patients.
The study is a prospective, single arm, phase II trial aimed to evaluate the efficacy and safety of Tumor Treating Fields (TTFields) concomitant with XELOX for the treatment of unresectable, locally advanced or metastatic Gastroesophageal Junction (GEJ) or Gastric (GC) Adenocarcinoma who were previously untreated with systemic therapy. The device is an experimental, portable, battery operated device for chronic administration of alternating electric fields (termed TTFields or TTF) to the region of the malignant tumor, by means of surface, insulated electrode arrays.
This Project aims to provide social workers and relevant human service professionals with a comprehensive, scientific, and validated service model and suggest a sustainable support framework on the working process of helping and empowering family caregivers of frail elders, reducing caregiving distress, and enhancing caregivers' quality of life. The proposed Project consists of two parts to be conducted in 1 year. The first part focuses on the development and validation of Caregiver Support Model (CSM) with a Randomized Controlled Trial (RCT) study. The second part develops and validates a psycho-education program on empowering family caregivers with another Randomized Controlled design. In the first year, the Project Team have (1) developed and designed different components of the Caregiver Support Model (CSM), including a comprehensive need assessment tool, personalized Caregiver Intervention Plan Guidelines and Template, and online database on caregiver services and community resources, (2) designed a five-session psycho-education program on empowerment. The Caregiver Needs Assessment (CNA) tool was also pilot-tested with 320 community caregivers. Results from the survey, together with the systematic review on caregiver support, will form the backbone of the later CNA implementation. The working model will be validated using RCT design with 400 family caregivers recruited through 4 collaborating NGOs. At the same time, a psycho-education program on empowerment will be developed and validated using RCT design with another 190 caregivers.
Obstructive sleep apnea (OSA) is a common chronic disease and associated with cardiovascular and neurocognitive sequelae. Overweight is a common, reversible risk factor of OSA, and the rapid rise in obesity worldwide may lead to increases in OSA and related adverse health outcomes. Weight-loss interventions, especially comprehensive lifestyle interventions, are associated with improvements in OSA severity, cardiometabolic comorbidities, and quality of life. However, the intensive nature of these programmes often pose a barrier to adherence. Furthermore, although there is strong evidence to support the value of mobile text messaging to promote physical activity and healthy eating in clinical and community settings, messaging has rarely been applied in interventions for overweight OSA subjects. The proposed study aims to examine the feasibility of a brief lifestyle modification programme that makes use of smartphone technology (WhatsApp or WeChat) to empower subjects to start doing simple and easy-to-do exercises that can be easily integrated into daily life for gradual lifestyle change.
