Filter by:This project aims to ascertain that novel imaging and metabolic markers can be used to identify as well as to validate and improve the detection of Singapore-Chinese women at increased risk of diabetes.
Despite exercise training decrease blood fasting glicaemy in 'average' terms, there is a wide inter-individual variability after exercise training explored mainly in adults but not in adults with prediabetes comorbidities. Thus, is yet unknown the effects and influence of the concurrent training (CT) eliciting responders (R) and non-responders (NR) cases (i.e., percentage of subjects who experienced a non-change/worsened response after training in some metabolic outcomes).
Obesity and pre-diabetes threatens the overall health and functional independence of older adults but lifestyle weight management for diabetes prevention, soon to be reimbursed by Medicare, can reduce this burden. The current 24-month study will enroll adults, ages 60 and older, through senior community centers and research registries. The investigators will study how two long term weight loss maintenance programs, both using group telephone sessions to support health behavior change, impact meaningful health outcomes. If successful, this project will provide a sustainable intervention model for healthy aging services that can benefit older adults and society.
This research will assess the feasibility of conducting a randomised control trial to evaluate the effectiveness of a 15-minute one-to-one consultation to improve blood glucose control in pre-diabetes. The consultation will take the form of a 15-minute one-to-one consultation between a health-care practitioner and the patient in a primary care setting. Patients with a glycated haemoglobin (HbA1c) of between 42 and 47 mmol·mol-1 will be identified in general practise and will be eligible to participate. They will attend testing sessions at baseline (before the consultation), and at three months and six months post consultation. Body mass index (BMI), waist and hip girth, blood pressure and body composition will be recorded and blood analysed for HbA1c, cholesterol and dietary components. For a three-week period following each visit, urine will be collected, a 5-ml sample on nine occasions, and physical activity will be recorded in a sub group of participants. Urine will be analysed by flow infusion electrospray mass spectrometry (FIE-MS) to determine the metabolic content, providing an indication of the diet over the three-week sampling period. The research objectives are to assess the effectiveness of recruitment strategy and willingness of patients to engage in, and adhere to, the research process; to determine the impact of consultation on health outcome measures, including HbA1c, and to establish participant and practitioner perspectives of the consultation.
A quantitative prospective cohort study will be conducted, where blood samples will be collected at different timings during the IVF protocol, to assess the impact of fertility medications on metabolic parameters of patients undergoing IVF treatment.
The primary objective of the proposed study is to examine and understand the impact of long-term almond consumption on chronic glucose metabolism in subjects with impaired glucose tolerance and/or impaired fasting glucose.
This study will evaluate a VA MyHealtheVet Secure Messaging intervention that uses different intervention messaging strategies designed to increase engagement in behaviors to prevent type 2 diabetes. The investigators will enroll 144 eligible Veterans into a 12-week MyHealtheVet Secure Messaging intervention. Eligible Veterans include those who are currently using MyHealtheVet secure messaging, meet inclusion/exclusion criteria, and have received an HbA1c test within the last 6 months that meets the ADA/CDC classification for prediabetes. Study participants will be surveyed about their engagement in behaviors to prevent TDM2 and mediators of this engagement. After completing a baseline survey, participants will be randomly assigned to receive different novel presentations of information about ways to prevent T2DM through both Secure Messaging and US Mail. The investigators will test the 5 presentations that each: (1) represent an innovative approach from behavioral economics or health psychology with great promise to increase engagement in behaviors to prevent T2DM among patients with prediabetes; and (2) have not been tested in this setting.
This study evaluates the effect of different doses of metformin on the function of endothelium in people with pre-diabetes. One group of the patients will receive metformin in dose: 1500 mg, the second one will receive 3000 mg/day. The parameters from healthy volunteers will be taken only at the study beginning to compare the test results with the parameters from patients with pre-diabetes. This group will be not treated with metformin (no intervention)
Determine the effects of reducing whole-body iron stores in overweight/obese subjects (via one-time blood donation) on adipose tissue iron content, factors regulating iron homeostasis and lipolytic rate in adipose tissue, as well as measures of adipose tissue and whole-body insulin resistance. After a screening visit to determine eligibility, subjects will undergo a battery of tests for the determination of primary outcome measures at baseline. They will then donate 1 unit (~500 mL) of blood (at a local blood donation center) and return for a follow-up testing 4 weeks after blood donation. During the 4-week period between study trials, subjects will be required to maintain a stable body mass and not alter their dietary or physical activity habits.
Physical activity is a first line treatment for patients with type 2 diabetes (T2D), however, the vast majority of patients with T2D do not achieve satisfying glycemic control with physical activity alone, which is why pharmacological treatment with metformin is most often initiated. It is known that metformin and exercise both activates 5' adenosine monophosphate-activated protein kinase (AMPK) in skeletal muscle and liver, and the activation of AMPK results in many different metabolic effects, including improvements in glycemic control. Because of this similarity in mechanism of action, an interaction between metformin and exercise is plausible, but knowledge in the area is sparse. Thus, the aim of this study is to assess the effects of acute physical activity with and without concomitant metformin treatment, in order to investigate whether an interaction between the two occur. Subjects with impaired glucose tolerance will be randomized (1:1) to metformin/placebo treatment in a double-blinded way. Following a treatment run-in period of 17 days, two experimental days (one with acute exercise and one without acute exercise), separated by one week, will be performed in each subject. This registration concerns a sub-study of another study which has previously been registrered at ClinicalTrials.gov (Unique Protocol ID: H-17012307). The specific outcomes in this registration have not previously been registered.
