Filter by:Objectives: To evaluate the effectiveness of active opportunistic screening using point-of-care capillary Hemoglobin-A1c (POC-cHbA1c) testing, compared to venous HbA1c (vHbA1c) testing, in improving detection of type 2 diabetes mellitus (T2DM) among at-risk primary care patients. Design: Pragmatic cluster randomized controlled trial. Setting: 8 public primary care clinics in Hong Kong. Participants: A minimum of 776 patients (97 per clinic) who have ≥1 risk factor for T2DM, but no known diagnosis of DM or DM screening in the past 12 months. Intervention: Participants at intervention clinics (n=4) will be offered free POC-cHbA1c testing on-site, immediately informed of test results and DM risk, and scheduled for confirmatory oral glucose tolerance test (OGTT) if screened positive (i.e. HbA1c≥5.6%). Participants at control clinics will be offered free vHbA1c testing scheduled on a separate day, informed of test results and DM risk via phone, and scheduled for confirmatory OGTT if screened positive. Main outcome measures: Primary outcomes are uptake rate of POC-cHbA1c versus vHba1c testing, and difference in proportion of T2DM detected between intervention and control groups. Secondary outcomes include number-needed-to-screen to detect one more T2DM case. Data analysis: Participants' characteristics and test uptake rates will be summarized by descriptive statistics. Difference in the proportion of T2DM detected between groups will be compared using Chi-squared test. Number-needed-to screen to identify one additional patient with DM will be calculated. Expected results: A greater proportion of T2DM patients will be detected by POC-cHbA1c than vHbA1c due to a higher screening test uptake rate among the studied population.
The goal of this observational study is to investigate changes in nocturnal and postprandial glucose and glycogen metabolism in individuals with impaired fasting glucose and impaired glucose tolerance compared to healthy, non-diabetic, overweight participants (15 per group). In addition, it will be investigated if reducing gluconeogenesis, by using the challenge agent Acipimox, in people with prediabetes can increase glucose tolerance and fat oxidation by increased reliance on hepatic glycogen. The main questions this project aims to answer are: - whether there are differences in nocturnal glucose/glycogen metabolism in individuals with impaired fasting glucose, impaired glucose tolerance and healthy overweight controls. - whether there are differences in postprandial glucose/glycogen metabolism in individuals with impaired fasting glucose, impaired glucose tolerance and healthy overweight controls. Participants will visit the university for a screening visit and a visit with overnight stay for measurements of gluconeogenesis, glycogen, and substrate oxidation. A subgroup will receive [18F]-FDG to assess tissue-specific postprandial glucose uptake. Thereafter, 20 prediabetic individuals will follow a 4-day treatment with acipimox to decrease gluconeogenesis, followed by a second overnight visit with similar measurements as mentioned for the first visit.
The main clinical study objective is to confirm the accuracy of the Glyconics-DS spectrometer when used in its intended medical purpose population, i.e., in individuals with unknown diabetes risk. Additionally, this investigation will serve as a pivotal performance evaluation for the associated software for correct delivery of the algorithm-based analysis of the individual diabetes risk. The study will be considered positive if the backend delivery of the chemometrics output is performed correctly as per the cloud-based analysis and its delivery represents the essential medical software to be evaluated in this investigation. The 'true' diabetes risk will be contrasted against values of an internal biomarker indicative of glycaemia, HbA1c, as measured based on standardised, certified methodology.
The goal of the Self-monitoring With Internet Technology to Choose Healthy Diets (SWITCH) study is to examine a 12-week remotely delivered program designed to help adults adopt a healthy dietary lifestyle and lose weight in a diverse cohort of adults with overweight/obesity. The intervention uses a self-determination theory framework to provide a deeper understanding of the factors that influence dietary behavior within the context of tracking. This study incorporates autonomy-supportive strategies to encourage participants to feel more in control of their dietary choices and will provide information and resources to boost participant's competence in achieving their dietary goals. The intervention includes weekly learning modules to support healthy eating and weight loss and daily dietary tracking with visual feedback, all accessible within the SWITCH app.
In the present study the investigators will examine whether people living with prediabetes benefit from an e-health lifestyle intervention of three months.
The goal of this pilot study is to assess the feasibility of the intervention (WB-EMS Training) in a sedentary group of adults with pre-diabetes and to estimate the potential effect sizes. The main goals and questions it aims to answer are: - Acceptability WB-EMS training in sedentary adults with pre-diabetes, - Has WB-EMS training positive effects on HbA1c and other biomarkers? Researchers will compare the intervention group with two control groups to see if WB-EMS training has effects on pre-diabetes.
The proposed research is designed to extend previous research findings building on the knowledge of strawberries as fruits that support a healthy immune and vascular system. The proposed research leverages a recently funded proposal by the USDA to study in greater depth inflammation, glucoregulation and oxidative stress defense and their relation to improving endothelial function and insulin sensitivity. Before and after strawberry intake, blood samples will be collected for monocyte (immune cells and source of inflammatory cytokines) isolation and activation via changes in cellular NF-κB and Nrf-2 (key transcription factors of inflammation/oxidative stress defense) status along with products of their activation (ie., plasma cytokines). Because inflammation and oxidative stress impairs endothelial function and insulin sensitivity, acutely and chronically, investigators will also study changes in vascular and insulin sensitivity status, assessing changes in vascular adhesion molecules, endothelial responsiveness through flow mediated vasodilation (ie., FMD) and insulin sensitivity using the Liquid Meal Tolerance (LMTT) if intravenous glucose tolerance test (IVGTT) method cannot be used due to supply chain issues of sterile Dextrose. Glucoregulation will be assessed by placing a Continuous Glucose monitoring (CGM) machine (Dexcom-6) to participants for 10 days at the beginning and at the end of the study period of intervention. The study will be a randomized, double-blinded, 3-arm parallel, 4-week, dose-response study. Individuals with chronic low grade inflammation will be sought to test the anti-inflammation - vaso-relaxing - insulin sensitivity effects of strawberry.
The research area that focuses on the links between nutrition and health, nutrition and the immune system as well as nutrition-related public health interventions, which often falls into the gap between the agricultural and health domains. The rationale of this project is to study the influence of beneficial diets on the immune system of pre-diabetic patients and its potential to counteract infections. A clinical, an in vitro (cell systems) and an in vivo (animal model) approach will be used to study the influence of a seaweed bioactive supplement and a diet rich in components from a Mediterranean diet on a Salmonella typhimurium infection in prediabetic subjects. At the end of this project, we will provide evidence on the potential of these nutritional interventions to counteract infection, which are of high relevance to the society to reduce the burden of type 2 diabetes (T2DM) and obesity. This research is part of an ongoing research project funded by the Research State Agency (Spain), Health Research Board (HRB, Ireland) and the Medical Research Council (MRC-UKRI, UK) via the NUTRIMMUNE' Grant of the Joint Programming Initiative a Healthy Diet for a Healthy Life (JPI-HDHL).
People with type 2 diabetes are at risk of complications linked with high blood sugars and these are monitored for in healthcare appointments. However, people with type 2 diabetes commonly suffer with additional health conditions that can affect the liver, heart and their breathing while sleeping. These conditions are thought to be caused by a similar underlying process that causes type 2 diabetes, as a result they are very common in people type 2 diabetes. Despite this they are not part of the routine health check for these people. Worryingly, current research suggests that the risk for developing these health problems, and direct complications of type 2 diabetes, can start at blood sugar levels below the threshold of type 2 diabetes. In a group of people said to have prediabetes. These people do not currently undergo annual healthcare appointments to monitor for these health complications or other linked health conditions. This study aims to pilot a new style of clinic to address these issues. The investigators will perform a multi-morbidity assessment, where they will look for several different health problems at the same time. The investigators will be looking at health problems linked with high blood sugars, this will include problems with the liver, heart, nerves, eyes, and participants breathing overnight. They have developed a clinic visit which uses questionnaires, simple examination techniques and modern devices to try and identify these health problems. An important part of healthcare is the burden it places on people with health problems, with this in mind the investigators will be giving the people involved in their study a voice to try and direct future research and healthcare, the investigators will ask them to provide feedback on their experience in taking part in the study and what their thoughts are in undergoing a longer but more comprehensive health appointment.
This single-arm trial of the Cardiovascular Risk Reduction Among People Experiencing Homelessness (CV-Homes) intervention alone (n=8) will test the perception and feasibility of anticipated study procedures.
