Active clinical trials for "Hyperglycemia"

The purpose of this study is to develop and test modified milk protein products to determine the effects of amino acids on food intake, satiety, insulin secretion and glucose control by insulin-independent action in healthy adults.

The study aims to assess whether a nutritional drink taken before conception and continuing through pregnancy, assists in the maintenance of healthy glucose metabolism in the mother and promotes offspring health.

Consumption of carbohydrate containing foods or sugary drinks brings about changes to the blood glucose levels. After a meal or drink, blood glucose rises until it reaches a peak concentration usually after 30 minutes. When the body senses the increase in blood glucose, a hormonal process involving insulin takes place to ensure that the glucose is taken up from the blood for storage and where it is needed for energy in the body. This process then brings about a decrease in the concentration of glucose until it reaches approximately the starting concentration. The original concentration of glucose is attained approximately 2 hours after eating or drinking a carbohydrate food or sugary drink respectively in healthy people. Different carbohydrates and sugary drinks have different effects on blood glucose response depending on the amount as well as the type of carbohydrate. Those that give rise to a high glucose response compared to a reference carbohydrate (usually glucose) are said to be high glycaemic index (GI) foods and those with a lower glucose response compared to a reference carbohydrate (usually glucose) are said to be low glycaemic index (GI) foods. Research has shown that diets that give rise to a high glucose response are associated with a number of abnormalities like increased risk of metabolic syndrome. Metabolic syndrome mostly comprises of insulin resistance and glucose intolerance which gives an increased risk of type 2 diabetes. It also gives rise to other conditions like high blood pressure (arterial hypertension), elevated blood insulin levels (hyper-insulinemia), elevated amounts of fat in the liver (fatty hepatosis) and elevated amounts of lipids in the blood (dyslipidemia). After type 2 diabetes become clinically apparent, the risk of cardiovascular disease also rises. Research has also shown that foods/drinks which raise blood glucose levels gradually (low GI) rather than rapidly (high GI) have health benefits which include reducing the risk of metabolic syndrome. Laboratory studies have shown that polyphenols found in fruits, vegetables and plant based foods have a positive effect on carbohydrate metabolism and can lower the blood glucose levels. This research will determine whether the presence of polyphenols in the diet has any lowering effect on the blood glucose levels and hence the glycaemic index of foods. This will be determined by asking volunteers to consume commercially available food supplements together with white bread and then determining the glycaemic response. The blood glucose response of bread will be determined initially as a control reference. All will be consumed in random order. Analysis will be done by measuring blood glucose response after consumption of the control reference meal and the test meal containing polyphenols and then determining the incremental area under the glucose curve. POMEGRANATE AND OLIVE STUDIES WILL BE TREATED SEPARATELY FOR PURPOSES OF PUBLISHING RESULTS. EACH STUDY WILL AIM TO HAVE AT LEAST 16 PARTICIPANTS.

Hypothesis: A beverage with a resistant starch will blunt and sustain the post-prandial rise in blood glucose and insulin concentrations compared to beverage with maltodextrin (an easily digested carbohydrate).

Primary research question: What is the effect of indoor rowing, under the ideal circumstances of a laboratory setting, on glucose control in adults with impaired glucose control? Secondary research question: Is it possible to develop a full-scale study of the benefits of indoor rowing under the usual circumstances of a community setting? Why? It is good practice to conduct a small pilot study before embarking on an expensive full-scale study. What? Around 150 minutes of aerobic exercise and around 150 minutes of resistance exercise per week are necessary to meet prevailing recommendations for adults with impaired glucose control. Around 120 minutes of indoor rowing per week might be a less time-consuming alternative to prevailing recommendations because indoor rowing involves a combination of aerobic and resistance exercise. Who? Twenty men and postmenopausal women aged 45-65 years with impaired glucose regulation, such as those with type 2 diabetes. Eligible volunteers will not have smoked in the last year, will not have exercised regularly in the last six months, and will not be taking any form of diabetes medication other than metformin. Eligible volunteers will have stable weight and a body mass index of 25-40. Where and how? Before and after the exercise intervention, glucose control (postprandial blood glucose concentrations) will be assessed at Leicester Diabetes Centre and cardiac function (MRI) will be assessed at Glenfield Hospital. During the exercise intervention, participants will use an indoor rower three times per week for 12 weeks at Leicester Diabetes Centre. Participants will be taught how to row correctly and the duration and intensity will gradually increase. In order to inform the design of a full-scale trial, recruitment rate will be assessed, adherence will be monitored, and a third party will interview participants to find out if the intervention and assessments are feasible and acceptable.

The purpose of this study is to test whether using extra doses of aspart insulin to correct blood sugars before meals improves the care of patients with type 2 diabetes in the hospital who are already receiving the standard of care treatment with glargine and aspart insulin injections to control blood sugar levels. Studies done in the past indicate that blood sugar levels are controlled on the standard treatment of insulin and that most patients do not need the small extra dose of insulin at bedtime. The investigators want to test if there is any benefit to giving patients extra doses of insulin during the day to correct the high blood sugars.

Those that give rise to a high glucose response compared to a reference carbohydrate (usually glucose) are said to be high glycaemic index (GI) foods and those with a lower glucose response compared to a reference carbohydrate (usually glucose) are said to be low glycaemic index (GI) foods.(1) Research has shown that diets that give rise to a high glucose response are associated with a number of abnormalities like increased metabolic syndrome (2). Metabolic syndrome mostly comprises of insulin resistance and glucose intolerance which gives an increased risk of type 2 diabetes. (3) It also gives rise to other conditions like high blood pressure (arterial hypertension), elevated blood insulin levels (hyper-insulinemia), elevated amounts of fat in the liver (fatty hepatosis) and elevated amounts of lipids in the blood (dyslipidemia). After type 2 diabetes become clinically apparent, the risk of cardiovascular disease also rises. (4) Research has also shown that foods/drinks which raise blood glucose levels gradually (low GI) rather than rapidly (high GI) have health benefits which include reducing the risk of metabolic syndrome (5). In vitro studies have shown that polyphenols found in fruits, vegetables and plant based foods have a positive effect on carbohydrate metabolism and can lower the blood glucose levels. (6) This research will determine whether the presence of polyphenols in the diet has any lowering effect on the blood glucose levels and hence the glycaemic index of foods. This will be determined by asking volunteers to consume polyphenol rich drink/food together with white bread and determine the glycaemic response. The GI of bread will be determined initially as a reference. Analysis will be done by measuring blood glucose response to white bread alone as reference and then to white bread with test sample containing polyphenols and then determine GI and see how the GI of bread will be affected. Other analyses to be done are plasma insulin, glucagon, gastric inhibitory polypeptide (GIP) and glucagon like peptides-1 (GLP-1) as they all relate to glycaemic response. Study hypothesis is that glucose metabolism will be affected. NOTE: Only healthy participants undertook the study (Hence metabolic syndrome participants not part of the study) Only glucose and insulin were analysed in the plasma (hence GIP, GLP-1 and glucagon not part of end points)

The purpose of this study is to investigate how millet incorporation into different baked product types influences glycemic response and satiety.

Normal glucose uptake and metabolism in skeletal muscles are essential to keep blood glucose within normal range and hence, insulin resistance (possibly mediated by inflammatory processes) in skeletal muscle is a major pathogenic factor in type 2 diabetes. Physical activity seems to be of essential importance in the prevention and treatment of type 2 diabetes. Myokines are proteins secreted from skeletal muscle that can execute important biological functions locally in the muscle (paracrine) or in other organs like the brain, heart and pancreas (endocrine). Evidence suggest that several interleukines and other cytokines are secreted by skeletal muscles. In the present project, the investigators will explore the relation between secreted myokines from muscle cells, insulin resistance and glucose metabolism before and after 12 weeks of exercise intervention. Subjects with normal as well as impaired glucose metabolism will be included in the study.

80 children aged 5-13, BMI≥85%, will be recruited to a program for the treatment of overweight children.The intervention group will use the app "Just Dance Now" and The control group will be exposed to the usual program without the app. Measurements will be performed at the beginning of the program, the end and 3 months after completion of the intervention.
