Filter by:This survey is designed to investigate the effect of highland barley β-glucan supplementation on the regulatory of blood glucose, gut microbiota and cardiovascular risk fators in subjects with hyperglycemia.
The first aim of this study is to describe maternal hormonal and inflammatory changes during pregnancy in women that differ metabolically (limited to women with type 2 diabetes, gestational diabetes and/or overweight). The second aim of this study is to examine maternal hormonal, inflammatory and metabolic factors associated with insulin sensitivity in human pregnancy.
Impaired fasting glucose (IFG) is a condition that precedes diabetes and increases the risk of developing it. Studies support the hypoglycemic effect of Cynara cardunculus (Cs) extracts due to the content of chlorogenic acid, which is a potent inhibitor of glucose 6-phosphate translocase and of dicaffeoylquinic acid derivatives that modulate the activity of alpha-glucosidase. Given this background, we investigated whether a new highly standardized Cs extract could improve glycaemic control, insulin sensitivity and other metabolic parameters (total, HDL and LDL cholesterol, Triglycerides, ApoB, ApoA, waist circumference, Visceral adipose tissue by DXA) in overweight subjects with newly diagnosed IFG.
To evaluate the effect of estradiol with or without a prior gonadotropin releasing hormone analogue on insulin sensitivity and vascular function in transgender females compared to cisgender controls.
About 14 healthy participants, consume a standardized breakfast combined with either using regular or nicotine-free moist snuff. The metabolic rate is measured every hour for four hours on each occasion starting in the morning. Participants are also randomized to get red wine or non-alcoholic red wine to the meal.
This 12 week placebo-controlled study evaluates the efficacy and safety of E. hallii supplementation.
Childhood obesity is one of the most serious public health problems of the 21st century. It is considered that if there are no changes in prevention and treatment strategies there will be an increase to 70 million obese children by 2025. Of the only pharmacological treatments accepted at this age to improve insulin resistance is metformin, but it can condition gastrointestinal, muscular and hepatic adverse events. Cinnamon is an alternative therapy, which due to its high concentrations of polyphenols, improves insulin resistance by decreasing the proinflammatory environment that occurs in this group of patients, and unlike metformin with less frequent adverse events. The effectiveness of cinnamon has been demonstrated by decreasing insulin resistance in the adult population.
The process of surgery is a controlled trauma to the body. Trauma induces changes in metabolic function that have evolved to help the body survive injury. The normal balance among use of sugar, fat, and protein for energy production is thought to change during trauma and surgery. This altered metabolic function may contribute to adverse outcomes from surgical procedures especially in the setting of patients with obesity or Type 2 Diabetes Mellitus. However, very little is known about the specific changes in metabolism that occur during surgical procedures. The main objective of this project is to describe the metabolic changes that occur during a typical surgical procedure in detail. In order to measure the alterations in the balanced use of sugar, fat, and protein during surgery we will collect blood samples from patients before, during, and after spinal surgical procedures. Subjects will be enrolled in the pre-operative hold area, give informed consent, and have a dedicated peripheral IV catheter placed. We will recruit patients who are normal weight without diabetes, obese without diabetes, and obese with diabetes. The first specific aim is to characterize the metabolic changes in sugar, fat, and protein balance during surgery in metabolically normal subjects. The second specific aim to examine if there are differences in these changes in subjects who are obese or have diabetes. The final specific aim is to measure the changes in metabolism at high resolution using a method called metabolomics, which is analogous to genome profiling. This method measures hundreds of compounds produced in different amounts as metabolic balance changes. The major impacts that may be derived from these data range from a more thorough understanding of metabolism under trauma to identification of new markers for risk stratification and intervention to improve clinical outcomes. These data will help build the foundation for new approaches to understanding the physiological and metabolic responses to stress and trauma.
Purpose/Objectives: To investigate the effect of hyperglucagonemia on insulin action, particularly on adipose tissue. Research Design/Plan: Normal glucose tolerant subjects will be studied. Study subjects will receive a continuous glucagon infusion for 12 hours. Following glucagon infusion, subjects will receive prime-continuous tracer infusions for additional 4 hours to measure adipocyte metabolism. Within 6-8 weeks, subjects will return for a repeat study with normal saline as a control group. Methods: All subjects will have an oral glucose tolerance test prior to participation to confirm they are normal glucose tolerant. Subjects will be admitted to the CRC at 4 PM and will receive a continuous glucagon for 12 hours. At 6 AM on the following morning, subjects will receive prime-continuous tracer infusions of the following for 4 hours (14C-glycerol, 3-3H glucose, and D2O). At 10 AM continuous indirect calorimetry will be performed to determine rates of energy expenditure and glucose/lipid oxidation for 40 minutes. At 6 AM a surgical biopsy of abdominal adipose tissue will be performed for measurement of adipocyte metabolism. At 8 AM, the study team will infuse insulin/glucose to test for insulin sensitivity. Clinical Relevance: The results of this study will help the study team to further understand the pathophysiology of metabolic disturbances that is induced by hyperglucagonemia in type 2 diabetes patients.
Probiotics are defined as live microorganisms that, when administered in adequate amounts, confer a health benefit on the host. Smectite is a natural silicate clay belonging to the dioctahedral smectite class formed from aluminomagnesium silicate. It is not absorbed from the gastrointestinal tract, but binds to intestinal mucous, forms multilayer structure with high plastic viscosity and powerful coating properties hence preserving integrity of the mucus, and has the ability to absorb directly bacterial toxins, bacteria, viruses and bile salts. The current study aim was to conduct placebo-controlled randomize clinical trial for the efficiency of a combination of multiprobiotics with smectite (Symbiter-Forte formulation) as an adjunction to the standard anti-diabetic therapy on IR, glycemic control parameters, β-cells functional activity, anthropometric parameters and markers of a chronic systemic inflammatory response in type 2 diabetes patients.
