Filter by:The investigators will conduct a single-arm mixed methods pilot study to estimate weight loss as well as the percentage of participants who achieve 5% weight loss in a 16-week, Low-Carbohydrate Diabetes Prevention Program (LC-DPP). Weight loss from the pilot LC-DPP cohort will be compared to weight loss outcomes from previously published DPP studies. The investigators will also evaluate secondary outcomes including change in physical activity, mental health, psychosocial functioning, and hemoglobin A1c over the 6-month study period.
Overweight/obese Chinese and prediabetes will be recruited and divided into three age-matched groups including high intensity exercise, moderate intensity exercise, and non-exercise groups. The exercise program will consist of three sessions per week over the course of 12 weeks, under the supervision of our in-house exercise specialists and physiologists. The effects of exercise on glucose and lipid profiles, insulin sensitivity and adiposity will be evaluated.
BACKGROUND AND OBJECTIVES: Cardiovascular disease is the leading cause of death despite huge primary and secondary prevention policies with a strong economic burden. The primary objectives of the ILERVAS project are: (i) to identify unknown factors involved in the presence of atherosclerosis, metabolic syndrome, pre-diabetes and hidden kidney disease in a low/moderate cardiovascular risk population; (ii) to identify unknown factors involved in the progression of atherosclerosis, metabolic syndrome, pre-diabetes and hidden kidney disease in a low/moderate cardiovascular risk population; (iii) to Assess of the impact of arterial ultrasound on cardiovascular events and mortality in a low/moderate cardiovascular risk population. METHODS: Randomized intervention study. From 2015 to 2018, 16,660 participants (8,330 in the intervention group (Mobile Unit Follow-up Group) and 8,330 in the no intervention group (Electronic Medical History Follow-up Group )) aged between 45 and 70 years without a previous history of cardiovascular disease and with at least one cardiovascular risk factor will be randomly selected across the province of Lleida, Spain.
Recently, various sodium glucose cotransporter 2 (SGLT2) inhibitors have been approved for the treatment of type 2 diabetes mellitus. Empagliflozin is a preparation of this class of substances. SGLT2 inhibitors also lead to a reduction in body weight in addition to their blood glucose lowering effect. The basis for this is probably the calorie loss by the increased glucose excretion over the urine. However, this weight-reducing effect is lost after a few weeks of treatment and the body weight subsequently stabilizes at a lower level than before. However, patients continue to lose energy via the urine. Hence, the weight stabilization could be due to an increased energy intake as a possible consequence of a changed brain setpoint for the body weight. As the main weight loss is achieved during the first 6-8 weeks of treatment, the investigators assume that the underlying central nervous mechanisms will be present after this time. Furthermore, clinical-experimental observations show that treatment with empagliflozin promotes endogenous glucose production in the liver. This presumably compensatory mechanism also occurs after only a few weeks of treatment. The common mechanism, which could be based both on energy intake and on the endogenous glucose production effect, is still unclear. The investigators suspect that regulatory circuits in the brain contribute to these observed effects. In fact, several studies in animals as well as initial clinical studies in humans show that the brain is involved in eating behavior and peripheral metabolism. In particular, effects of the hormone insulin modulate the dietary intake via the brain, thereby affecting human body weight. Many of the experiments on the insulin sensitivity of the human brain used a specific approach to the selective delivery of insulin into the brain: the application of insulin as a nasal spray. Although this application route has no therapeutic value, this technique allows the administration of insulin to the central nervous system with little effect on the circulating insulin levels. By combining nasal insulin administration with functional MRI, regional insulin sensitivity of the brain can be quantified. The investigators recently found that the insulin action of the brain (stimulated by nasal insulin) regulates both endogenous glucose production and peripheral glucose uptake during hyperinsulinemic euglycemic glucose clamps. The signals from the brain seem to reach the periphery via the autonomic nervous system in order to modulate metabolic processes. A central brain area in this regard is the hypothalamus. This brain region receives afferents over various systems such as the autonomic nervous system and various endocrine systems (including insulin). The investigators recently characterized the hypothalamus as an insulin-sensitive brain area in humans. The hypothalamus is the key area for homeostatic control throughout the body. Since the dietary intake and the endogenous glucose production are modulated by a hypothalamic insulin effect in humans, we suspect that the observed effects of SGLT2 inhibitors on both processes could be due to altered insulin activity in the brain. Since the SGLT2 inhibition by empagliflozin modulates the autonomic nervous system in the kidneys, signals from the kidney may be transmitted to the brain via the autonomic nervous system, thereby changing specific setpoints, including e.g. insulin sensitivity of the brain. In order to test this hypothesis, a precise phenotyping of prediabetic volunteers with regard to regional brain insulin sensitivity as well as the brain effect on metabolism before and after 8 weeks of treatment with empagliflozin compared to placebo is planned.
Background: A significant proportion of pre-diabetics, show macro and micro vascular complications associated with hyperglycaemia. Although many trials have demonstrated the efficacy of lifestyle and pharmaceutical interventions in diabetes prevention, no trial has evaluated the extent to which mid- and long-term complications can be prevented by early interventions on hyperglycaemia. Aims: To assess the long-term effects on multiple complications of hyperglycaemia of early intensive management of hyperglycaemia with linagliptin, metformin or their combination added to lifestyle intervention (LSI) (diet and physical activity), compared with LSI alone in adults with non-diabetic intermediate hyperglycaemia (IFG, IGT or both). Study Design: Investigator initiated (non-commercial), long-term, multi-centre, randomised, partially double blinded, placebo controlled, phase-IIIb clinical trial with prospective blinded outcome evaluation. Participants will be randomised to four parallel arms: 1) LSI + 2 placebo tablets/day; 2) LSI + 2 Metformin tablets of 850 mg/day; 3) LSI + 1 Linagliptin tablets of 5 mg/day and 1 placebo; 4) LSI + 2 tablets of a fixed-dose combination of Linagliptin 2.5mg and Metformin 850 /day. Active intervention will last for at least 2 years. Setting and population: Males and Females with pre-diabetes (IFG, IGT or both) aged 45 to 74 years selected from primary care screening programs in 14 clinical centres from 10 countries: Australia, Austria, Bulgaria, Greece, Italy, Kuwait, Poland, Serbia, Spain and Turkey and . (N=1000) Main Outcomes: The primary endpoint is a combined continous variable: "the microvascular complication índex" (MCI) composed by a linear combination of the Early Treatment Diabetic Retinopathy Study Scale (ETDRS) score (based on retinograms), the level of urinary albumin to creatinine ratio, and a measure of distal small fibre neuropathy (sudomotor test by SUDOSCAN), measured during baseline visit and at 24th and 48th month visits after randomisation. In addition, serological biomarkers of inflammation, vascular damage, non-alcoholic fatty liver disease, insulin secretion, measures of quality of life, sleep quality, neuropsychological evaluation and endothelial function will be also evaluated in a subset of participants.
The lifestyle intervention program focusing on healthy dietary habit and exercise effectively prevents progression to diabetes. Thus, the purpose of this study was to assess the effectiveness of lifestyle intervention program on pre-diabetics subjects in Taiwan.
The objective of this trial is to compare the effects of a healthy, lean beef diet and an average American, United States Department of Agriculture (USDA) style diet, that is low in saturated fatty acids (SFA), on insulin sensitivity in men and women with risk factors for diabetes mellitus.
Individuals with prediabetes are at increased risk for developing diabetes. Higher hemoglobin A1c's (6.1-6.4%) are associated with a high risk of developing diabetes. It is known that programs such weight management classes and one-on-one counseling with registered dieticians can lead to weight loss and decrease the risk of diabetes. However, engagement of Kaiser Permanente Colorado members in these activities is low. The purpose of this study is to determine which of three outreach methods is most effective in increasing engagement in these activities.
The primary purpose of this pilot study is to test a novel head worn light device (Re-Timer®) as an intervention to improve glucose metabolism in people with prediabetes. The hypothesis is that morning light treatment will improve glucose metabolism. This is a pilot study and the data from this project will be used to develop a larger clinical trial.
This pilot study aims to determine whether adding a sleep extension and sleep hygiene intervention to an existing lifestyle improvement program improves its efficacy for weight loss in those at risk for diabetes and cardiovascular disease. Half of the participants will receive the Centers for Disease Control's standard PreventT2 program and half of the participants will receive the same program with an additional sleep intervention.
