People with poor insulin sensitivity do not respond normally to elevations in blood sugar. This may increase their risk of developing diabetes in the future. The purpose of this research study is to determine if the nutrient betaine, found in beets, spinach and wheat products, can enhance the production of fetal growth factor 21 (FGF21), a molecule that is believed to promote insulin sensitivity.
The Metabolic Syndrome is a high prevalence disease worldwide. About a quarter of the adult population suffers the disease. Resveratrol is a substance found in many plants, including grapes, nuts and wine, but it's also found in Polygonum cuspidatum. There is evidence that resveratrol consumption has beneficial effects on glucose and lipids metabolism, blood pressure and body weight. The aim of this study was to evaluate the effect of resveratrol on metabolic syndrome, insulin sensitivity and insulin secretion. The investigators hypothesis was that the administration of resveratrol modifies the metabolic syndrome, insulin sensitivity and insulin secretion.
Background To evaluate clinical results, insulin resistance and inflammatory response to trauma in morbidly obese patients undergoing laparoscopic Sleeve gastrectomy who received either traditional preoperative care or treatment following the ACERTO protocol.
The Metabolic Syndrome is a high prevalence disease worldwide. About a quarter of the adult population suffers the disease. Dapagliflozin is an inhibitor of the sodium-glucose co-transporter SGLT2 in the kidney and is a novel treatment for diabetes type 2. Some studies indicate that SGLT2 inhibitors have benefits on blood pressure, triglycerides levels and help to raise the levels of high density lipoproteins cholesterol (c-HDL). The aim of this study is to evaluate the effect of dapagliflozin on metabolic syndrome, insulin sensitivity and insulin secretion. The investigators hypothesis is that the administration of dapagliflozin modifies the metabolic syndrome, insulin sensitivity and insulin secretion.
The investigators seek to examine the metabolic changes that occur amongst obese and lean pregnant women with normal glycemic control as well as pregnant women with diabetes mellitus (gestational diabetes and pre-existing type 2 diabetes mellitus) compared to non-pregnant age matched controls. Given the adaptive tendency of the maternal body to use alternative energy sources such as ketones and free fatty acids rather than glucose and to shunt glucose and amino acids to the fetus, the investigators hypothesize that the amino acid and fatty acid profile will be reflective of this adaptive change and that maternal insulin resistance will result in alterations in this pattern in both the plasma and CSF. Furthermore, the investigators also hypothesize that maternal degrees of insulin resistance will also be reflected in CSF hormonal changes.
A goal of this study is to use a novel methodology to determine whether insulin resistance in women with polycystic ovary syndrome (PCOS) is related to the accumulation of proteins with modifications. This could lead to future research to determine if these modifications interfere with their proper function. Additionally, the investigators will determine how protein quality is affected by exercise training. Aerobic exercise enhances the endogenous oxidant buffering systems which may minimize oxidative damage to proteins. The investigators propose that aerobic exercise minimizes the accrual of modified proteins by increasing the synthesis of new proteins, but also by increasing the degradation and removal of old and damaged proteins. Based on our previous studies the investigators observed that insulin affects plasma protein synthesis and aerobic exercise improves insulin sensitivity not only in muscle but also in liver. The investigators therefore propose that aerobic exercise and related increase in insulin sensitivity (and decline in insulin levels) will reduce accumulation of old and modified skeletal muscle and plasma proteins leading to improved function.
Insulin resistance is closely associated with apparition of type 2 diabetes mellitus; it is an independent risk factor and predicts future cardiovascular events. Hyperinsulinemic euglycemic clamp is a validated method to assessment of insulin resistance and It is also the gold standard technique. However, the complexity and length of this technique render it unsuitable for routine clinical use. In this study, the investigators use a new technique to provide precise, objective, fast and automated quantification of insulin resistance with camera SPECT. They compare the results with those of the measurement of hyperinsulinemic euglycemic clamp in population with or without insulin resistance. The proposed study is to validate this new non-invasive imaging technique for evaluation of insulin resistance in patients with or without insulin resistance with a comparison with hyperinsulinemic euglycemic clamp.
The average American diet consumed by a significant proportion of the adult population, supplies excessive calories and large amounts of saturated fat. Saturated fats can be cleared and used in skeletal muscle, but in obese individuals, biomarkers of saturated fat are found in the blood, along with markers of poor muscle metabolism. Both fats and amino acids are processed by the same metabolic pathways in muscle, and the investigators hypothesize that meals with greater amounts of saturated fat slow muscle metabolism. A better understanding of the interaction of these to metabolites will allow for the development of future medications to treat muscle loss in sick individuals and the elderly.
The childhood obesity epidemic, which falls disproportionately on Latino adolescents, represents a major public health threat to the current generation of youth, and therefore to the health of the nation overall. This project directly addresses the role of psychosocial stress in promoting obesity and metabolic disease risk, and investigates the role of the mind-body CAM intervention of guided imagery in both reducing stress and promoting healthy lifestyle behaviors that could dramatically improve the metabolic health of today's youth.
