Active clinical trials for "Hyperglycemia"

A natural sweetener (Stevia Rebaudina Bertoni) reduces blood glucose levels and blood pressure according to various preclinical and clinical studies conducted worldwide. Since it is not found many studies in the literature wich compares Stevia Rebaudiana with saccharin, we've proposed a randomized crossover clinical trial comparing the effects on postprandial capillary blood glucose and blood pressure in healthy adults. Sample: healthy professionals from two health centers in Alava (Kakuabizkarra primary care center and Txagorritxu hospital). Inclusion criteria: Professionals of two health centers of Álava (Lakuabizkarra and Txagorritxu) and active employment status at the beginning of the trial, weighing more than 50kg and age over 18 years. Intervention: 200mg capsules of Stevia or 250mgcapsules of saccharin. Measurements: Capillary blood glucose and blood pressure, fasting and after eating. Evaluation of satiety, hunger and fullness by questionnaire after intake, and at the end of the day. Statistical analysis: Compare the postprandial capillary glucose levels between 8 am and 1 st hour, 2nd hour 3rd hour after intake between treatments by ANCOVA. We will also compare blood pressure before and after intake between treatments. We will also compare by t test or paired Wilcoxom (depending on the nature of the variable) the results of the questionnaire after intake between treatments.

This study aims to determine the most effective strategy of reducing sedentary behavior to improve health. Specifically, we aim to answer the following questions: (a) To determine if there is a significant difference in acute post-prandial glucose response between continuous sitting and two intermittent standing regimes (high frequency, low duration breaks (HFLD) and low frequency, high duration breaks (LFHD)). We hypothesize that intermittent standing (combined HFLD breaks and LFHD breaks regimes) will result in lower overall acute post-prandial glucose compared to continuous sitting. (b) To determine if there is a significant difference in acute post-prandial glucose response between two strategies to reduce sitting with standing (HFLD standing breaks vs. LFHD standing breaks). We hypothesize that the HFLD breaks condition will elicit lower acute post-prandial glucose level compared to the LFHD breaks condition. All eligible participants will be consented and subjected to all three study conditions: (i) Uninterrupted sitting, (ii) HFLD breaks, and (iii) LFHD breaks. The order at which participants were subjected to these conditions will be randomly determined and each condition were performed a week apart. Standardized meals (breakfast and lunch) will be provided during each lab visit and participants will be then be asked to perform their usual work activity using a sit-stand workstation in the lab. Depending on their assigned condition, the participants will be prompted to stand or sit for a given period of time. A continuous glucose monitor will be used to measure glucose response to the intervention while an activPAL device will be used to make sure that participants are compliant with the study protocol.

Type 1 diabetes (T1D) is a lifelong disease which stops the body from producing insulin - an important hormone that controls blood sugar (glucose) levels. People with T1D use insulin replacement therapy, usually in the form of injections, to help control blood glucose levels, however keeping glucose levels within normal ranges is usually a challenge. Mealtime glucose control is fundamental to good diabetes management and are an important contributor to long-term diabetes complications. However, many individuals experience variability in glucose levels around mealtimes. The objective of this study is to establish whether and which parameters are important predictors of mealtime glucose levels in people with T1D. The investigators will monitor glucose levels using the latest glucose monitoring technology and collect blood samples to: Characterise changes in glucose levels in individuals with T1D in response to different meals Determine whether and what food characteristics and personal factors are linked to individual glucose responses to different meals. The investigators will recruit 150 individuals with type 1 diabetes. Firstly participants will attend a preliminary visit, where a blood sample will be donated to study laboratory blood markers of vascular and metabolic health accompanied by a full medical examination in which body composition will be established. During this visit participants will also complete questionnaires about their lifestyle, and be fitted with two wearable devices to monitor glucose levels and physical activity levels under free-living conditions. After 4-weeks of wearing the devices, participants will attend two experimental laboratory visits where breakfast and lunch will be served and blood samples taken. This will enable us to observe glucose and metabolic responses to feeding under controlled conditions.

The average adult in the US consumes over 1/3 of a cup of sugar each day, or nearly 300 calories worth, with the primary sources being from beverages, desserts and sweet snacks, candy, additions to beverages, and foods such as breakfast cereals. This is a risky health behavior, as high added sugar intake relates to higher risk of gaining weight, blood sugar disorders such as type 2 diabetes, plus heart disease and various cancers. Thus, high added sugar intake is problematic, and something in need of reducing. Therefore, the investigators are proposing to test how commercial foods sweetened with a new, FDA approved rare sugar with net zero calories (allulose), that is derived from dried fruits, brown sugar, and maple syrup may impact added sugar intake and usual blood sugar levels. The investigators are doing this by a randomized trial, in which the investigators will recruit participants with abnormal blood sugars (prediabetes or diabetes) or higher metabolic risk (bigger waist and elevated blood pressure or blood cholesterol) and ask them in random order to include foods in their usual dietary intake that are sweetened by regular sugars (regular sugar), foods that are sweetened by the zero calorie rare sugar allulose (low added sugar), or low added sugar intake by higher intake of fresh fruits and minimally processed and sweetened foods in place of usual sweetened foods. The investigators will measure their usual blood sugar levels for each of these 3 different 2- week periods with a blood glucose monitor, along with what they eat each of those periods, their blood pressure, and how the different dietary approaches impact how they feel.

The purpose of this study is to determine whether treatment with sitagliptin reduces the frequency and severity of high blood sugar (hyperglycemia) after cardiac surgery and to determine whether treatment with sitagliptin is effective in maintaining blood sugar control in patients with type 2 diabetes (T2D).

Physical activity performed in the postprandial state has the ability to blunt postprandial glycemia acutely, even as a result of very light or small amounts of postprandial physical activity. Postprandial physical activity decreases postprandial glycemia more effectively than activity performed in the post-absorptive state. However, studies comparing postprandial and postabsorptive physical activity have measured glycemic outcomes in only short periods of time (hours) or have used a very large dose of physical activity. Physical activity have the ability to entail an acute increase in markers of systemic inflammation.Previous studies has also shown that systemic inflammation is increased during glycemic spikes, such as after a high carbohydrate load. Therefore the effect of postprandial physical activity is difficult to predict. One one hand it might increase markers of systemic inflammation. On the other hand it might decrease systemic inflammation as a result of a blunting effect on postprandial glycemia. The effect of physical activity after carbohydrate intake might therefore also differ from postabsorptive physical activity. Purpose of the study: I) The investigators hypothesized that light physical activity performed in the post-prandial sate decrease blood glucose in a day and night cycle compared to the same activity performed in the postabsorptive state and a control day. II) To test whether postabsorptive and postprandial light physical activity do affect markers of systemic inflammation different. 12 participants diagnosed with hyperglycemia but not on hypoglycemic medication took part in a randomized cross-over trial with 3 test days. A control day with no physical activity, and two days similar to the control day except that one of them contained a one hour bout of treadmill walking prior to breakfast and the other a similar exercise bout after breakfast. Continuous glucose monitoring was performed from start of exercise / breakfast until the morning next day (at least 22 hours). Venous blood was also sampled at given timepoints (before exercise / before breakfast, and 1.5, 2.5, 3.5 and 24 hours after breakfast. Dietary intake was individually standardized prior to and during test days.

Raised blood glucose levels can lead to adverse modifications to functional proteins within the body and eventually lead to the development of type 2 diabetes. Fruit polyphenols may help to control glycaemia following a carbohydrate meal or beverage. The aim of this study is to investigate the effects of blackcurrant (BC) and apple (A) extracts on postprandial glycaemia, insulinaemia and plasma gastric inhibitory polypeptide concentrations following a mixed carbohydrate test meal.

This 3-armed randomized controlled trial aims to evaluate the effectiveness of The Microclinic Behavioral Health Program in improving obesity and diabetes risk factors through a behavioral intervention program structured to enhance and promote social-network interactions and social support. The full version of the Microclinic Behavioral Health Program (Full MCP) with program-activated social-network interactions-with shared access to diabetes education, technology, and group support to promote weight and metabolic control through diet, exercise, medication adherence, and blood pressure management. Participants play a role in the collective effort to combat diabetes and solidifying self-management behavioral skills through peer-monitoring and encouragement of lifestyle behaviors. The study may yield valuable information on the impact of social support and social network interactions for enhancing body weight and blood sugar control. We compare the full MCP intervention, to a basic MCP intervention with more limited classroom interaction, and to an parallel monitoring control arm. This Microclinic Behavioral Health Program was established in collaboration with the Royal Health Awareness Society (RHAS) and the Jordanian Ministry of Health (MoH).

Primary Aim: To test the acute effects of olanzapine or ziprasidone administration, in comparison to placebo, on insulin sensitivity in antipsychotic-naïve healthy young men, measured as whole-body dextrose infusion rates (mg/kg/min), hepatic glucose production (glucose rate of appearance [Ra]), primarily muscle glucose utilization (glucose rate of disappearance [Rd]), and adipose tissue related free fatty acid production (glycerol rate of appearance [Ra]). We hypothesize that olanzapine, but not ziprasidone, will result in acute decreases in insulin sensitivity. Secondary Aim: To test the acute effects of olanzapine or ziprasidone on insulin signaling pathways in antipsychotic naïve healthy young men. We hypothesize that olanzapine, but not ziprasidone, will result in acute alterations in insulin signaling.
