There are about 3015 clinical studies being (or have been) conducted in Singapore. 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.
Supracondylar humeral fractures are the most common elbow fractures in children and cast immobilization continues to remain as the recommended treatment for modified Gartland's classification Type I and Type IIa injuries. Apart from plaster of Paris and fibreglass casts, the use of waterproof, tubular hybrid mesh (HM) casts have been gaining traction for cast immobilization. Although the use of HM cast has been reported to have similar clinical outcomes and overall patient satisfaction scores to the fibreglass cast, the results of the recent studies are only limited and generalizable only to paediatric distal radius fractures. As the application method of HM and fibreglass casts are fundamentally different, it has not been reported if the difference in application duration between the cast materials is significant and its potential implications in outpatient clinic operation. Hence, through a randomized controlled trial, this study primarily aims to investigate if the clinical outcomes, patient satisfaction and duration of cast application with the HM casts would be comparable with fibreglass casts in children with supracondylar humeral fractures. Through this study, the investigators hope to evaluate the advantages and disadvantages of the respective casting material which may better aid physicians in deciding a more appropriate cast material for treating paediatric supracondylar humeral fractures with cast immobilization and the implications of casting duration on clinic operations.
The purpose of this study is to deliver dual-targeting CAR-T cell therapy (CART 2219.1) as a salvage treatment to patients with relapsed/refractory B-lineage leukaemia in place of stem cell transplant or irradiation.
Using a 3-arm randomized controlled trial, the investigators aim to rigorously evaluate the effects of two different taxation policies on diet quality. The first is an implicit sales tax that will be levied only on beverages in a manner that mirrors the current Kingdom of Saudi Arabia (KSA) beverage taxes and the second is an explicit Nutri-Score (NS) based tiered tax that is levied on all food and beverage products. The investigators will use an experimental online grocery store, called NUSMart, which is similar in design to commercial web-based grocery stores to test these two taxation policies. Participants will be randomly assigned to one of the following arms and asked to complete a one-time hypothetical shop. Arm 1 (Control): Participants will experience a default version of NUSMart which replicates the traditional shopping experience of online grocery stores with no FOP labels. Arm 2 (Implicit Tax): Same as Arm 1 NUSMart except that an implicit tax will be levied only on beverages: a 50% sales tax on carbonated drinks and sugar-sweetened beverages (SSBs) and 100% tax on energy drinks (milk, milk-based products, and natural fruit juice are excluded). Arm 3 (Explicit Tiered Tax): Same as Arm 1 NUSMart except that an explicit tiered tax based on (underlying) NS is levied on (sale price of) all food and beverages. NS assesses overall nutritional quality of products on the basis of 7 nutrients (calories, saturated fats, sugar, salt, fiber, protein and percentage of fruits, vegetables and nuts) from A to E (best to worst). In this arm, the investigators implement a 20% sales tax on the retail price for NS D beverages and 10% for NS D foods along with a 50% sales tax on NS E beverages and 20% on NS E foods. The investigators hypothesize the following: Hypothesis 1: Diet quality of food purchases, measured by the weighted average Nutri-Score point, will be highest in the explicit tiered tax arm, followed by the implicit tax arm, followed by the control. Hypothesis 2: Average calories, sugar, sodium, and saturated fat per serving will be lowest in the explicit tiered tax arm, followed by the implicit tax arm, followed by the control.
Asthma attacks which are moderate-to-severe are typically treated with corticosteroids, but the optimal treatment duration is unknown and treatment responses can be variable. Inadequate treatment may compromise recovery, but increased exposure to corticosteroids is, in turn, associated with drug-related adverse effects. There is a need for a biomarker to guide duration of corticosteroid treatment in asthma attacks. One such candidate biomarker is the blood eosinophil count, which may predict steroid-responsiveness. We hypothesize that the blood eosinophil count can potentially be used as a biomarker to guide the duration of corticosteroids in moderate-to-severe asthma attacks. This study will recruit individuals hospitalized for asthma attack. Participants will be randomized to standard care or blood-eosinophil guided systemic corticosteroid therapy. Subjects in the standard arm will receive oral corticosteroids for a total of 5 days. Subjects in the blood-eosinophil guided arm will receive oral corticosteroids for a total of 5 days if admission eosinophil count is ≥ 0.300 x 10^3/µL, and receive 3 days of oral corticosteroids if the admission blood eosinophil is < 0.300 x 10^3/µL. The rate of treatment failure will be compared between these two groups.
The key objective of the study is to compare the effects of soft tissue augmentation using a volume stable collagen matrix or autogenous connective tissue graft or no soft tissue augmentation in addition to bone grafting/implantoplasty in patients who undergo surgical therapy of peri-implantitis with respect to clinical resolution of the infection.
This is a randomized, blinded, placebo-controlled, dose-ranging Phase 1b study of the safety, PK, and antiviral activity of ABI-H3733 in treatment-naïve or off-treatment chronic Hepatitis B virus (cHBV) subjects that are Hepatitis B e antigen (HBeAg) positive or negative. The study will enroll up to 5 sequential cohorts of 10 subjects each, for a total of up to 50 subjects, randomized 8:2 to receive ABI-H3733 or placebo.
Cannulation of complex arteriovenous fistula (AVF) or graft (AVG) is a challenge to renal nurses. Ultrasound (US) guidance on central and peripheral venous access visualisation has been widely adopted in nephrology and shown to reduce complications of vascular interventions. With broader adoption of handheld US devices in clinical services, renal nurses could acquire this point-of-care technique to increase the successful cannulation rate while facilitating confidence build-up during training and practice. We aim to evaluate the use of handheld US on difficult AVF/AVG cannulation in a hospital-based dialysis unit.
Decision aids are highly recommended for decisions when there is no "right" treatment choice. The goal is to help patients choose a treatment that is consistent with their preferences and to minimize decisional conflict and regret. A case where there is no "right" treatment concerns the decision to undergo dialysis or supportive care (i.e., conservative management) for elderly (aged ≥70) patients with end-stage kidney disease. The investigators propose to develop an interactive web-based decision aid and test its effectiveness via a pre-post study design. This research aims to reduce decisional conflict for elderly ESKD patients and caregivers.
The key objective of this study is to identify the most suitable diet (i.e. high protein, high fat, low GI, high GI) for an individual. Importantly, we further seek to identify the biological determinants of inter-individual variability and to understand how these determinants affect blood glucose. The deep metabolic phenotyping, multi-omics profiling of each subject and fine-mapping of their glycemic responses to different diets will allow us to obtain preliminary data on the mechanistic basis underlying inter-individual dietary glycemic response. Data from this study will form the basis of large clinical trials, the development of novel foods, and/or novel technologies to alter the gut micro-biome for optimal blood glucose control.
