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.
The rate of falls in patients after total knee arthroplasty (TKA) is high and related to lower limb muscle weakness and poor balance control. However, since routine post-TKA rehabilitation is uncommon, it is paramount to explore alternative strategies to enhance balance and physical functioning in post-TKA patients. As Tai Chi is a proven strategy for improving balance in older people, the proposed study aims to determine the feasibility and acceptability of a 12-week community-based post-TKA multimodal Tai Chi program and to collect preliminary data with respect to the efficacy of such a program in improving balance and physical functioning in post-TKA patients as compared to usual postoperative care.
Iron deficiency anaemia is a common condition among colorectal surgical patient. Untreated anaemia would lead to increase in blood transfusion, surgical complications and mortality. Treatment with oral iron sulphate is poorly tolerated due to side effects. Intravenous iron supplement provides an alternative way to rapidly replace iron deficit during the preoperative period among surgical patients. Evidence is growing for its effect in rising hemoglobin level and reducing blood transfusion, at the same time supporting its safety profile. The investigators plan for a single-centered, randomized controlled trial to examine the effect of intravenous iron compared to standard care in terms of hemoglobin level/serum ferritin increment, need for blood transfusion, duration of hospital stay, quality of recovery and surgical complication rate, as well as safety profile among colorectal cancer surgical patients in Hong Kong. The investigator propose the following pilot RCT for exploring the effect size and study process in conducting the above-mentioned large-scale RCT.
As part of the ZOSTER-006 and ZOSTER-022 pivotal trials of the HZ/su vaccine, all study participants completed quality of life (QoL) questionnaires. The only questionnaires encoded into the data base were those from participants who developed a suspected shingles episode during the study. The purpose of this study is to allow for the encoding and analysis of questionnaires for all subjects enrolled in ZOSTER-006 and ZOSTER-022. The aim is to assess the baseline frailty of subjects enrolled in these studies and to investigate whether this population is representative of the general population.
The objective of the study is to compare the bioavailability of a generic product of paracetamol (immediate-release) with that of a reference product when administered to healthy volunteers under fasting condition. The test product is Fortolin Tab 500mg manufactured by Fortune Pharmacal Co. Ltd., and the reference product is Panadol Caplet 500mg manufactured by GlaxoSmithKline (Dungarvan) Ltd. The plasma pharmacokinetic data of paracetamol obtained from two formulations will be used to evaluate the interchangeability of the products.
In recent decades, following an increased longevity in Hong Kong, there is a drastic increase in the prevalence chronic conditions, including chronic pain, seems to be the main reasons of suffering for many older adults. This condition not only pose a burden to the whole family but also the healthcare system. While conventional treatment of chronic pain using pharmacotherapy and non-pharmacological treatments has been effective for managing symptoms, owing to the adverse side effects caused by anti-psychotic drugs and the short effective period incurred by non-pharmacological interventions, development of alternative and non-pharmacological approaches for the management of pain is of urgent need. Research has shown that aromatherapy (both administered through inhalation and therapeutic massage) has been effective in reducing showing pain-relieving effects. These findings support the premise that aromatherapy and the investigators hope to provide further evidence to support the use of aromatherapy as an evidence-based mainstream intervention for pain relief in older adults with chronic pain. Whilst there is sufficient evidence to support the effectiveness of aromatherapy, few studies compared the effectiveness of the use of aromatherapy by inhalation and/or therapeutic massage. The investigators aim to address the above research gaps on the clinical application of aromatherapy on chronic pain, with a focus on comparing the differential effectiveness between administration by inhalation and administration by therapeutic massage. The proposed research aims to (1) test the efficacy and effectiveness of aromatherapy on the symptom management of chronic pain in older adults; (2) compare the effects of aromatherapy-scent (i.e., inhalation) and aromatherapy-touch (i.e., therapeutic massage) in older adults with chronic pain. This study also explores the benefits of aromatherapy on cognitive functioning, functional performance and social engagement as secondary outcomes. A randomized, controlled, and single blinded trial is proposed. 120 older adults with chronic pain will be randomly assigned to aroma inhalation (intervention), aroma-touch or wait-list (control) treatments. Pain intensity and subjective changes in mood states (primary outcome), cognitive functioning, functional performance and social engagement (secondary outcome) will be assessed three times: pre-treatment, mid-treatment, post-treatment. If the study hypotheses are supported, the findings will provide empirical support for a treatment option that could improve manage the symptoms of patients diagnosed with chronic conditions, and also improve cognitive functioning, functional performance, and social engagement of older adults.
This is an international multicentre prospective cohort study to validate the Bayes theorem based algorithms for the screening of pre-eclampsia (PE) in the first-trimester of pregnancy.
Malnutrition has long been linked to postoperative complications and adverse outcomes in a variety of surgical fields , such as increased susceptibility to infection, delayed wound healing, and increased frequency of decubitus ulcers. In particular, it is a modifiable risk factor, as evident by studies that have associated optimization of preoperative nutrition with improved surgical outcomes. Therefore, it is important to identify these patients who are at risk so that appropriate nutritional support can be implemented. A range of options for nutritional status assessment have been proposed; a comprehensive assessment may include measurements of dietary intake, clinical assessment, anthropometric measurements, and biochemical measurements of serum protein, micronutrients and metabolic parameters . Many of the signs of malnutrition, however, only manifest in extreme cases. Thus it is crucial to identify sensitive markers that can be utilized to screen for clinical as well as subclinical malnutrition patients. In orthopaedic patients, the prevalence of clinical and subclinical malnutrition has been reported to be up to 42.4%. Common markers of malnutrition that have been studied include low serum albumin as a marker of protein status, low total lymphocyte count (TLC), and excessively high or low body mass index (BMI). They have been compared against various adverse surgical outcomes, including surgical site infections (SSI), delayed wound healing, unplanned intubation and ICU admission , postoperative anemia and cardiac complications , and length of hospital stay. However, conflicting results have been reported; for example, while hypoalbuminemia (serum albumin <3.5mg/dL) have been associated with increased risk of SSI and longer than average hospital stay, its effect on wound healing is less clear - Marin et al. reported no significant predictive value of hypoalbuminemia on wound healing, yet Greene et al. reported a 5-time increase in frequency of major wound complication. The purpose of this retrospective cohort study was to identify biomarkers of malnutrition in patients undergoing elective total knee arthroplasty (TKA) that are predictive of adverse in-hospital postoperative complications, which would facilitate the identification of at risk patients for nutritional optimization before surgery. Six-hundred and twenty-six patients who underwent elective TKA between 2013 and 2017 in the Prince of Wales Hospital in Hong Kong were reviewed; the preoperative serum albumin, TLC, and BMI were compared against in-hospital postoperative complications.
