There are about 3455 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.
This is a cohort study to understand the role of the human metagenome, and associated metabolites, in health and in various diseased states, in particular obesity as well as sarcopenia. Recruited participants will have their fecal, salivary, urine, serum, and in certain instances, mucosal samples taken, for metagenomic sequencing and metabolite testing. We hope to uncover various differences and signatures in the metagenome and metabolome in various diseased states, with potential future therapeutic applications in personalised medicine.
The SMART app is a mobile application based psychosocial parenting intervention containing educational materials (articles, videos, audios, podcasts) on parenting, an integrated peer support chat function with experienced mothers and an integrated forum for interaction with other mother participants. The goal of this interventional study is to test the effectiveness of a mobile-app health based intervention, SMART, mothers in the perinatal period. The main questions this study aims to answer are: 1. What is the effect of a mobile-based health intervention, SMART, on maternal outcomes? 2. What is the effect of a mobile-based health intervention, SMART, on infant outcomes? 3. What is the cost-effectiveness of using SMART as compared to standard routine care? Researchers will compare results with a control group that will undergo standard routine care.
The goal of this clinical trial is to investigate the repeatability of application of a fully remote method of manufacturing 3D printing of prosthetic sockets for transtibial amputees, and determine user satisfaction of sockets produced through these methods. The study also aims to evaluate the time and cost effectiveness of this production model. The main question[s] it aims to answer are: 1. To determine the repeatability and user satisfaction with transtibial sockets produced using a remote-digital method as compared to conventional manufacturing methods. 2. To determine if transtibial prosthetic users have greater prosthetic satisfaction scores across the 4 Prosthesis Evaluation Questionnaire (PEQ) subscales of Utility (UT), Appearance (AP), Sounds (SO) and Residual Limb Health (RL) with the 3D printed socket fabricated through the remote-digital method compared to the laminate socket made using the conventional method. 3. To determine if transtibial prosthetic users experience greater socket comfort with the 3D printed socket compared to the laminate socket. Participants will receive a 3D printed socket (trial intervention) and a laminate socket (control intervention) and will use each socket for a period of 4 weeks.The order of socket use will be randomised. At the end of each 4 week period, participants will rate their comfort and satisfaction with the socket. At the end of the trial, participants will indicate their preferred socket, which will be fitted to their prosthesis. Participants will attend 6 visits across a total duration of 11 weeks during the course of the study.
Non-communicable diseases (NCDs), such as cardiovascular disease, diabetes, or cancer, and common mental disorders (CMDs), such as depression or anxiety, represent the primary causes of death and disability worldwide, causing major health and financial burdens. Lifestyle behaviours, including physical activity, diet, stress and emotional regulation, tobacco smoking, alcohol consumption, and sleep are important modifiable risk factors associated with the prevention and management of both NCDs and CMDs. LvL UP is a mHealth intervention aimed at preventing NCDs and CMDs in adults from multi-ethnic Southeast Asian populations (Castro et al., 2023). Building upon leading evidence- and theory-based frameworks in the areas of mental health and behaviour change, a multidisciplinary team of researchers developed LvL UP as a holistic intervention centred around three core pillars: Move More, Eat Well, Stress Less. The goal of this pilot study is to assess the feasibility of a Sequential, Multiple Assignment, Randomized Trial (SMART) aimed at (i) evaluating the effectiveness and cost-effectiveness of LvL UP and (ii) establishing the optimal blended approach in LvL UP that balances effective personalized lifestyle support with scalability. The main questions it aims to answer are: 1. What are the intervention's preliminary, short-term effects? What is the intervention's level of engagement? What is the number of dropouts? What is the percentage of missing data? What is the intervention's responder / non-responder rate after week 4? How easy was to recruit the target sample size and which channels worked best? 2. Considering the above pilot study results: What is the overall feasibility of the SMART research protocol in its current form? Are there any changes required for the main trial? This includes: recruitment approach, intervention content and delivery (app, provision of human support), and/or trial assessments (online and in-person).
The purpose of this study is to compare the effectiveness and safety of golcadomide in combination with rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP) chemotherapy vs placebo in combination with R-CHOP chemotherapy in participants with previously untreated high-risk large B-cell lymphoma (LBCL).
The aim of the study is to investigate if hands-on training for basic CCE with virtual reality simulators or guided by artificial intelligence is non-inferior to training by an experienced instructor.
Schizophrenia patients commonly present with persistent negative symptoms which remain the main reason for dysfunction after recovery from an acute episode of psychotic symptoms. Negative symptoms in schizophrenia exact significant burden with no effective pharmacological or behavior treatment options thus far. Neuromodulatory modalities present a novel and alternative treatment approach and recent trials have shown preliminary evidence for the efficacy of intermittent Theta Burst Stimulation (iTBS) to treat negative symptoms in schizophrenia. In this study, we aim to examine the effectiveness of an accelerated iTBS treatment protocol as an augmentation treatment regime for patient in rehabilitation care with persistent negative symptoms. We propose a pragmatic, open label and single arm clinical trial. Forty patients with diagnosis of schizophrenia, who had been stabilized from psychotic symptoms and currently suffering from dominant negative symptoms will be recruited and undergo accelerated iTBS treatment for 5 consecutive sessions each day for 5 working days. Participants will be followed up immediately, 1 month and 3 months after the end of treatment. Clinical assessment includes, BNSS, The Brief Negative Symptom Scale; SANS, Scale for the assessment of negative symptoms; SAPS, Scale for the assessment of positive symptoms; PANSS, Positive and Negative Symptoms Scale; MoCA, Montreal Cognitive Assessment scale; CDSS, Calgary Depression Scale for Schizophrenia: SDS, Sheehans' disability scale and EQ-5D. The primary endpoint of the trial is the change of negative symptoms as assessed by PANSS, negative symptoms subscale immediately after the treatment. This study will determine whether accelerated iTBS is effective to be delivered as an augmentation therapy for patients with persistent negative symptoms. The optimal treatment system for this population can be immediately translated to clinical practice and benefit patients in need.
The goal of this randomized controlled clinical trial is to compare the immediate effectiveness of 3D intra-oral scanners and standard oral hygiene instructions in improving the oral hygiene of 52 subjects. The main question[s] it aims to answer are: - Does a 3D intra-oral scanner facilitate the improvement of oral hygiene in subjects? - Does a 3D-rendered image of plaque-stained teeth confer better visualization to subjects? Prospective Open Cohort study: Patients referred to NUCOHS Periodontology Department will be invited to participate in the study. Included participants will be randomized into the 3D scanner (test) and standard oral hygiene (control) group. Subsequently, both groups will receive personalized oral hygiene instructions before brushing their teeth. The participants will receive plaque disclosing again to compare the differences between baseline and post-intervention. Routine periodontal parameters will be recorded at baseline and researchers will compare the percentage improvement in full mouth plaque scores to see if the test group performed better than the control group. A questionnaire will be given to subjects in the test and control group for qualitative analysis. The study will require 1 visit.
This study aims to examine the effects of dietary nitrate supplementation via beetroot juice on sprint interval cycling exercise performance. Twenty-four participants (male or female) will undertake a randomized, crossover trial where they consume either (i) an isotonic beetroot juice drink containing nitrate (12.9 mmol) for 5 days or (ii) an isotonic sports drink (no nitrate) for 5 days. On Day 5 of each trial, participants will come to the laboratory and 2 hours after consuming their allocated drink will complete a 6 bouts of sprint interval exercise. Power output during cycling will be measured as the primary outcome measure. Salivary and plasma measures of nitrate and nitrite will be taken over the course of the morning on Day 5. After a 5-day washout period participants will crossover and begin their second trial.
This proposal seeks to conduct a pragmatic single arm, open label pilot implementation to validate our individualized functional Magnetic Resonance Imaging (fMRI) connectome-guided localization approach for accelerated TMS among Asian patients with depression. Participants will be patients with Major Depressive Disorder not responding to standard treatment, with no exclusions to fMRI or transcranial magnetic stimulation (TMS) (essentially metal implants in the head) and willing to participate in the pilot. All participants will undergo MRI scans before and after the accelerated TMS treatment. The multi-session hierarchical Bayesian model (MS-HBM) approach will be used to estimate individualized connectome-guided target locations. Patients will undergo accelerated TMS applied to individualized connectome-guided target locations (based on the MS-HBM approach). Patients will undergo 10 sessions (each session lasting 10 min) spread out over 10 hours each day for 5 consecutive working days. All clinical outcome data will be collected for each patient by a pre-defined questionnaire at four time points: at baseline, post-treatment, 1 month and 3 months during follow-up. The clinical outcome data will be analyzed using linear regression or repeated analysis of variance (ANOVA) after adjusting for baseline clinical characteristics and socio-demographics. Trajectories of the clinical outcome data at baseline, post-treatment and all follow-up time points will be plotted and compared with time series statistical analysis models with the other clinical and socio-demographic characteristics included as confounders.
