There are about 3491 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 study aims to examine whether listening to natural sounds in a noisy (traffic) environment compared to traffic noise only impacts behavioural, cognitive, affective, and physiological markers associated with attention restoration. Attention restoration will be examined as an aspect of cognitive fatigue.
The health benefits of fruits and their importance in a healthy diet have long been known. Several intervention studies have included the promotion of fruit as part of the healthy diet and epidemiologic evidences have demonstrated that a diet rich in fruits is associated with the reduction in the risk of many chronic diseases, including type 2 diabetes. Such beneficial health effects of fruits could be attributed to the presence of dietary fiber, micronutrients (vitamins and minerals), antioxidants and phytochemicals found in them. However, up to our knowledge, no study has investigate the time-course effects on the co-ingestion of fruits with other food product on postprandial glycaemic response (GR) and insulinaemic response (IR). The time-course effect will be examined in this study in order to determine its optimal effect on GR and IR. The investigators also aimed to compare the effects of varying micronutrients content in fruits on GR and IR.
A study in Finland found that a multidomain intervention of physical activity, nutritional guidance, cognitive training, social activities and management of vascular risk factors slowed cognitive decline in healthy older adults at increased risk of cognitive decline. A 6-month pilot study was initiated in Singapore, which demonstrated the cultural feasibility and practicality of the FINGER interventions and a set of locally adapted interventions in an Asian population. The SINGER study is a 2-year randomized controlled trial that aims to test the efficacy and safety of these lifestyle changes, including diet and cardiovascular risk factor management, cognitive and physical exercises, in delaying cognitive decline in older adults at risk of dementia.
Using a 3-arm randomized controlled trial, the investigators aim to rigorously evaluate the effects of two front-of-pack (FOP) food labels on diet quality. The first food label is a modified version of Chilean warning FOP label and the second food label is a modified version of French FOP label, Nutri-Score. The investigators used an experimental online grocery store, called NUSMart, which is similar in design to commercial web-based grocery stores to test these two FOP labels. Participants were randomly assigned to one of the following arms and asked to complete a one-time hypothetical shop. Arm 1: Participants experienced a default version of NUSMart which replicated the traditional shopping experience of online grocery stores with no FOP labels (Control). Arm 2: Same as Arm 1 NUSMart except that Chilean warning FOP labels were displayed on less healthy food and beverages. Products with specific nutrients (i.e. sugar, sodium, saturated fat, energy) falling outside the bounds of the thresholds defined by the Chilean warning labels were depicted with the warning labels on them. Arm 3: Same as Arm 1 NUSMart except that Nutri-Score FOP labels along with % sugar per serving were displayed on all food and beverages. These labels score products on the basis of 7 nutrients (calories, saturated fats, sugar, salt, fibre, protein and percentage of fruits, vegetables and nuts) from A to E (best to worst). To ensure that participants understood what Nutri-Score labels mean and how they work, an introductory video was shown before shopping. The investigators hypothesize the following: Hypothesis 1: Diet quality, as measured by weighted average Nutri-Score point of shoppers' final baskets, will be greatest in Arm 3, followed by Arm 2, followed by Control. Hypothesis 2: Grams of sugar per serving/ milligrams of sodium per serving/ grams of saturated fat per serving/ calories per serving will be least in Arm 2, followed by Arm 3, followed by Control.
Phantom limb pain (PLP), defined as pain felt in the missing portion of the amputated limb following amputation, occurs in a significant percentage of patients who undergo limb amputation and it is among the most difficult chronic pain syndromes to treat. Its incidence has been reported to be around 70% though a local pilot study in 2013 reported the incidence to be 25%. The investigators aim to determine the actual incidence of PLP by conducting a single-centre prospective cohort study and identify risk factors associated with PLP. Subsequently, the investigators will use identified risk factors to develop and validate a risk prediction model for PLP after amputation surgery and design interventional studies aimed at reducing the development of PLP in high risk patients.
With an ageing population, fragility fractures secondary to osteoporosis are on a increasing trend. Proximal humerus fractures are common fractures which account for a significant proportion of these fragility fractures. They significantly affect patients function and independence particularly in the elderly. Currently, treatment options range from conservative treatment with an arm sling to fixation either with plates or intramedullary devices to arthroplasty ranging from a hemiarthroplasty to the latest reverse shoulder arthroplasty. While is there has been a global trend towards surgical treatment for such fractures, there is significant controversy regarding the best treatment with many studies reporting disappointing functional outcomes including residual shoulder pain, limitation in shoulder motion and decreased quality of life regardless of treatment option selected. In this day and age where healthcare cost is a big concern both at the individual patient level but at a government level as well, evaluating the cost effectiveness of treatment becomes essential as well. Currently in Singapore, there have been a significant trend of an increased use of surgical treatment of proximal humerus fractures however we have very little data in our local context not only to evaluate the clinical effectiveness but also the cost effectiveness of surgical treatment in comparison to conservative treatment. The primary aim of the study is 1. To understand the epidemiology and prognostic factors for proximal humerus fractures - Incidence - Health service utilization - clinical and functional outcomes 2. To estimate the relative cost-effectiveness of surgical vs non-surgical treatment pathways for managing patients with proximal humerus fractures. We hypothesize that surgical fixation of the proximal humerus is both clinically and cost effective
A Phase 2/3 Study of Evorpacept (ALX148) in Combination With Trastuzumab, Ramucirumab, and Paclitaxel in Patients With Advanced HER2-overexpressing gastric/GEJ adenocarcinoma.
Work-related musculoskeletal disorders (WRMSD) among sonographers/radiographers are prevalent in the healthcare industry. This pilot study will evaluate the use of a robotic assisted ultrasonography system (ROBUST) against the conventional abdominal ultrasound scanning procedure. The ROBUST will be developed to provide 6 degrees of freedom to allow radiographers to perform abdominal scanning without having to reach over patients. 10 sonographers with at least 5 years of experience will be recruited from SGH and SKH, to perform abdominal ultrasound scans on healthy volunteers. Each sonographer will be randomly assigned to scan a volunteer using conventional abdominal ultrasound scanning procedure and with ROBUST respectively. The study will be done in 2 phases, separated by at least a 1-month interval between scans. Phase 1: Scanning of volunteer using conventional abdominal ultrasound scanning procedure. Phase 2: Scanning of volunteer using ROBUST. Outcome measures will include ultrasound image quality, sonographer feedback and comfort level as well as satisfaction feedback from healthy volunteers. A panel of 4 reviewers, consisting of 2 radiologists and 2 senior radiographers will be invited to grade the images, using a 3-point Likert scale. The duration of each scanning will be recorded. The comfort level reported by sonographers will be assessed using the SGH Comfort Level Survey. In addition, the comfort level of healthy volunteers will also be assessed using a satisfaction questionnaire.
The specific aim of the study will be to investigate the incidences and risk factors for postoperative delirium (POD) after hip fracture surgery in elderly patients aged ≥ 65 years in five different Southeast and East Asian countries. The secondary objectives are outlined below: 1. To investigate factors in the hospital environments, such as noise levels, ambient lighting, nursing ratios, ward bedding and climate control, that contribute to similarities and/or differences in POD occurrences in different countries and health systems 2. To investigate patient factors, such as disease burden, mental health, education levels, and socioeconomic factors, that contribute to similarities and/or differences in POD occurrences in different countries and health systems 3. To quantify the direct and indirect costs, as well as resource utilization, resulting from the development of POD in each country
Work-related musculoskeletal disorders (WRMSD) among sonographers/radiographers are prevalent in the healthcare industry. This study will evaluate the use of a robotic assisted ultrasonography system (ROBUST) against the conventional abdominal ultrasound scanning procedure. The ROBUST will be developed to provide 6 degrees of freedom to allow radiographers to perform abdominal scanning without having to reach over patients. 6 sonographers with at least 5 years of experience will be recruited from SGH and SKH, to perform abdominal ultrasound scans on 50 patients. Patients will be screened by the radiographers in the study team for their suitability in the participation during their scheduled appointments and will be invited to undergo scanning with the ROBUST upon agreement. Outcome measures will include ultrasound image quality, sonographer feedback and comfort level as well as satisfaction feedback from patients. A panel of 4 reviewers, consisting of 2 radiologists and 2 senior radiographers will be invited to grade the images, using a 3-point Likert scale to compare the images taken with ROBUST against the images taken conventionally prior to using the ROBUST. The duration of each session will be recorded. The comfort level reported by sonographers will be assessed using the SGH Comfort Level Survey. In addition, the comfort level of participating patients will also be assessed using a satisfaction questionnaire. The investigators hypothesize that there is no difference in imaging quality and comfort levels of sonographers and patients between a conventional ultrasound scan and scanning with the ROBUST. The investigators also hypothesize that there would be a reduction in the risk of WRMSD among sonographers with reduction in ergonomic risk factors.
