Active clinical trials for "Insulin Resistance"

Surgery induces insulin resistance lasting for 2-3 weeks. We wanted to elucidate if stress-metabolic, medical conditions carry the same effect.

Therapeutic effectiveness of coldness in relieving pain and reducing inflammation has been known for many years now. Over that time, various coldness therapies have gained in popularity, including winter swimming, snow baths or whole body cryostimulation (WBC) . Recent researches have shown positive effects of WBC on metabolic profile, low-to-moderate chronic inflammation and related diseases (e.g., obesity). WBC could be, thus, intended as an adjuvant method in the treatment of dysmetabolic conditions, such as overweight or obesity. WBC is a cheap easily accessible practice, with a few well-defined contraindications and limited non severe possible adverse events, if performed in specialized centres. At the same time, in sport science appears data, which indicated on inhibition of adaptive changes induced by regular training. The primary aim is to define, through a randomized controlled approach, the relative effectiveness of up to 20 consecutive sessions of either WBC, high-intensity intermittent training (HIIT), or their combination (WBC and HIIT) in improving the metabolic status of overweight and obese subjects. The effects will be assessed, at different time-points, in terms of insulin sensitivity and modification in the profile of hormones regulating the energy metabolism (adipokines, myokines, bone-derived hormones) and the inter-organ cross-talk.

This pilot study is designed to investigate the effect of water-only fasting and refeeding on the homeostatic model of insulin resistance (HOMA-IR), a measure of insulin resistance.

This observational pilot study will assess the effects of water-only fasting on body composition and insulin resistance

This research was planned to determine the level of nesfatin-1, known as satiety hormone, in type 2 diabetes, insulin diabetes and obesity patients and to determine whether there is a relationship between patients' energy intake levels. Additionally, it was aimed to evaluate the relationship between patients' nesfatin-1 values and serum glucose, insulin, lipid concentrations.

The purpose of this study is to determine whether night time eating that coincides with elevated endogenous melatonin impairs glucose tolerance, particularly in carriers of the MTNR1B risk allele.

This research study will examine how ethnic/racial background, body composition (%body fat), and the location of body fat affect the ability of the hormone insulin to promote uptake of blood sugar in persons who are 19 to 45 years of age. When insulin is ineffective in promoting blood sugar uptake, this condition is termed "insulin resistance." Insulin resistance plays a major role in the development of chronic metabolic diseases (such as type 2 diabetes, cardiovascular disease, and cancer), many of which differ with race. Previous studies suggest that insulin resistance is higher in African-Americans (AA) vs. European-Americans (EA). However, results from these studies remain unclear due to different testing measures used for insulin resistance as well as differences in body fat between individuals. Results from this research study may help explain why insulin resistance differs with genetic background and may guide development of personalized treatment strategies with implications for several chronic metabolic diseases (e.g., type 2 diabetes, cardiovascular disease, and cancer).

Millions of women suffer from overactive bladder, and the changes in bladder function affect their quality of life. The study team believes that it needs to be better understand why women get overactive bladder in the first place so that better treatments can eventually be offered. The purpose of this study is to determine why women with insulin resistance are more likely to get overactive bladder. Overactive bladder is a type of bladder control problem that can cause some women to have bladder leakage. This problem is more common in women with diabetes and pre-diabetes, but it isn't known why.

African Americans are at a substantially greater type 2 diabetes risk compared to Caucasians; however, very little data are available on the effects of exercise training on type 2 diabetes risk factors in at risk African Americans. The present proposal will evaluate the effects of 6 months of moderate versus vigorous intensity aerobic exercise training on fitness, insulin sensitivity, mitochondrial capacity, skeletal muscle oxidative/insulin sensitivity markers, adiposity, and quality of life in African Americans.

The aim of this study is to determine whether carnosine supplementation in overweight/obese individuals can improve insulin secretion and/or insulin resistance by decreasing sub clinical inflammation. The investigators hypothesise that carnosine supplementation will reduce type 2 diabetes and cardiovascular risk factors by lowering chronic low-grade inflammation (CLI), oxidative stress, advanced glycation end products (AGEs), and advanced lipoxidation end products (ALEs). Aim :To determine the capacity of carnosine supplementation to decrease major risk factors for type 2 diabetes and cardiovascular disease and identify metabolic pathways involved, specifically by: Reducing diabetes risk (insulin sensitivity; secretory function and glucose tolerance) Improving cardiovascular risk factors (lipids; arterial (aortic) stiffness; central blood pressure (cBP); endothelial function). Decreasing the CLI, oxidative stress, AGEs, and ALEs, and increase detoxification of reactive carbonyl species (RCSs).
