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.
Acute promyelocytic leukemia (APL) is characterized by t(15;17)(q24;21) and the fusion gene PML-RARA. We have formulated an oral preparation of As2O3 (oral-As2O3), and shown that it is efficacious for APL in R1, inducing CR2 in more than 90% of patients. Furthermore, in an effort to prevent relapse, we have moved oral-As2O3 forward to the maintenance of CR1. This strategy results in favorable overall-survival (OS) and leukemia-free-survival (LFS), implying that prolonged treatment with oral-As2O3 may prevent relapses. Current protocols have incorporated i.v.-As2O3 in the treatment of newly-diagnosed APL. In regimens comprising i.v.-As2O3, ATRA and chemotherapy, 5-year overall survivals in excess of 90% is achieved. In this study, we evaluate the use of oral-As2O3 and ATRA based induction regimens in newly diagnosed patients with APL. In this study, we evaluate the efficacy and tolerability of frontline oral arsenic trioxide-based regimen in newly diagnosed patients with acute promyelocytic leukaemia
Many studies, including our own, have shown that colorectal cancer (CRC) is related to changes in the microbiome of the colon. However, there are limitations in most studies and questions remained unanswered. Some early data showing that the microbiome in the left vs right colon are different. The aim of this study is to investigate the microbiome (including bacteriome, virome, and fungome) of adenoma/CRC comparing the left (distal to splenic flexure) vs right side (proximal to splenic flexure) of the colon.
NK malignancies consist of two different clinical entities, extranodal NK/T cell lymphoma and aggressive NK leukaemia. Queen Mary Hospital (QMH) had started to use PIGLETS chemotherapy for treatment of NK malignancies since 2013, with promising results. The study in QMH had ended because of successful recruitment in the planned number of subjects. When PIGLETS was used in extranodal NK/T cell lymphoma, patients with stage I/II lymphoma have an overall response rate of nearly 90%, while patients with stage III/IV disease have an overall response rate of around 60%. The figures are comparable to the SMILE chemotherapy previously used. However, PIGLETS regimen carries much lower risk of nephrotoxicity when compared with SMILE. It has since become a standard protocol in management of NK malignancies in our institution. PIGLETS chemotherapy carries two major problems: 1. the name PIGLETS may appear offensive to some religious populations. (e.g. Muslim) 2. significant nausea/vomiting was seen in previous studies, and these could at least be partially alleviated with substance P antagonist aprepitant Thus the investigators decided to start a study, renaming the original PIGLETS regimen into SIMPLE chemotherapy, adding aprepitant as antiemetics and to recruit more patients for evaluation of clinical efficacy. The results of SIMPLE chemotherapy will be compared to SMILE in a non-inferiority trial setting.
This study aims to evaluate the effectiveness of concurrent mirror therapy (MT) and transcutaneous electrical nerve stimulation (TENS) in augmenting the efficacy of the lower limb task-oriented training in people with stroke. It is hypothesize that MT combined with TENS would be superior to sham-mirror therapy with TENS, or MT with placebo-TENS, or control training only in improving lower limb motor functions and walking ability in people with stroke when combined with the lower limb task-oriented training.
Knee osteoarthritis (OA) is a common musculoskeletal disorder among older people. Since the prevalence of knee OA increases with age, it is anticipated that the prevalence and burden of knee OA will increase significantly given the aging population. Total knee arthroplasty (TKA) is used to treat patients with severe knee OA. While TKA has been shown to improve knee pain, function and quality of life of patients with knee OA, up to 50% of patients with post-TKA may suffer from falls within in the first year after TKA. Given that Tai Chi can significantly improve the balance and function of older people, a fall prevention program may improve balance, pain, and function of post-TKA patients. As such, the current 3-arm randomized controlled trial (RCT) aims to compare the effectiveness of a post-operative community-based fall prevention program in improving knee pain, function and balance of patients with unilateral TKA against a group of TKA patients receiving standard post-operative care, and age- and gender-matched asymptomatic controls over 1 year.
Evidence showed that both TENS and passive body heating are potential treatment strategies for improving cognitive functions in people with dementia. It is hypothesized that hat device (Warmth +TENS) over the 4 acupuncture points would induce a greater improvement in cognitive functions and behavioural symptoms when compared with other hat devices (Warmth + placebo-TENS; TENS only; Warmth alone) and Control (hat device with no warmth and no TENS).
Liver cancer is the fifth most common cancer and the second most frequent cause of cancer-related death globally. Hepatocellular carcinoma represents about 90% of primary liver cancers and constitutes a major global health problem. The pattern of HCC occurrence shows a significant geographical imbalance, with the highest incidence rates in East Asia (more than 50% of the cases occurring in China). The aim of this study is to investigate the overall survival (OS) of patients diagnosed with unresectable hepatocellular carcinoma under real-world practice conditions in Asia Pacific region.
Background: Preterm birth is the leading cause of perinatal morbidity and mortality in multiple pregnancies. The medical and educational expenditure and lost productivity associated with preterm birth is very high. Sonoelastography is a new ultrasound technology which has enabled the measurement of tissue stiffness and it has been widely applied in assessment of breast lump and liver cirrhosis. Sonoelastography is potentially useful for the objective assessment of cervical consistency which could be related to risk of preterm birth. Objective: To assess the cervical consistency by shear wave elastography in prediction of preterm birth in multiple pregnancies. Setting: This is a prospective non-interventional observational study. Subjects: Chinese women carrying multiple pregnancies attending antenatal visit are invited to join the study. Method: Demographic data and antenatal history will be obtained. Transvaginal scan for the cervix will be performed by a trained researcher or obstetrician for the assessment of cervical consistency, cervical length, posterior cervical angle and fetal viability. The measurements will be repeated during 5 antenatal visits or separate study visits at 11-15, 16-19, 20-23, 24-27 and 28-32 weeks of gestation. At the end of pregnancy, the delivery data and neonatal outcome will be collected. Sample Size: The risk of preterm birth <34 weeks in twin pregnancies is approximately 20%. A sample size of 120 was determined as being sufficient to test the diagnostic performance of cervical elasticity in mid trimester assuming that the risk of preterm delivery <34 weeks vs >34 weeks is 1:5 and that cervical elasticity area under curve (AUC) of the receiver operating characteristics (ROC) curve was 0.7, with 80% power and alpha of 5%. Data Analysis: Changes in the cervical elastography will be compared using the Student paired two-tailed t test, and in the case of unequal standard deviation (SD), using a Wilcoxon signed-rank paired two-tailed test. For comparison of frequencies, Chi-square test, or a two-sided Fisher exact test will be used where appropriate. Linear regression will be used to assess the correlations. The level of statistical significance is set at p<0.05 (two-sided).
The goal of this study is to develop a large longitudinal cohort of individuals diagnosed with or at high risk for brain diseases (both neurological and psychiatric in nature), in order to identify risk factors that contribute to neurological and psychiatric diseases over time. The investigators seek to capture relevant information from medical records, electronically administered questionnaires and follow up phone-based interviews. The investigators expect to eventually have sufficient power from our dataset to examine risk factors for a variety of brain disorders, both individually and in aggregate. Our ultimate goal is to offer scientifically validated ways to preserve and promote brain health by working with our patients' needs and tracking their progress over time.
It is hypothesized that reappraising intergeneration relationships through perspective-taking will enhance the well-being of adult-child caregivers. Incorporating both psychological and social perspectives, the study makes a unique contribution to address research gaps by evaluating an integrated model of intervention for dementia caregivers. The conceptual model involves the following components: 1) relational insights; 2) self-reflection to integrate the challenges and benefits in caregiving; 3) interpersonal empathy To test the incremental value of perspective-taking reappraisals, the study involves a two-arm randomized controlled trial of 12 weeks of intervention with two conditions: 1) Reappraisal through Perspective Taking and 2) Basic Skill Building. Telephone-administered sessions are integrated with group sessions and home visits to maximize sustainability and accessibility of the intervention. One hundred fifty-four participants will be recruited and randomized. Primary outcomes are reduced depressive symptoms and enhanced psychological well-being for the caregivers. Secondary outcomes include enhanced social support for caregivers and reduced behavioral problems in the care-recipients.
