Active clinical trials for "Insulin Resistance"

We aim to test the efficacy of a new method for determining individual insulin sensitivity (IS) based on sensor-augmented-insulin pump (SAP) data in order to customize the insulin to carbohydrate ratio (CR) in adolescents with type 1 diabetes (T1D). To date, the individual insulin sensitivity (IS) could only be investigated by intensive and invasive research techniques that are not feasible to perform in an outpatient setting for pediatric patients with diabetes. Recently published studies have demonstrated the efficacy of an algorithm to calculate the patient specific insulin sensitivity to customize the CR for adult patients with T1D. The algorithm has been validated in adult patients, however not yet investigated in the pediatric population with T1D. The aims of our study are: to customize the CR of pediatric subjects with T1D using the individualized insulin sensitivity index (ISind) to improve post-prandial blood glucose control after a standard meal. to test, under free living condition (at home), the efficacy of the customized CR in improving post-prandial glycemic control for pediatric subjects with T1D. This approach would have at least two potential benefits for pediatric patients with T1D: To provide a non-invasive tool for individualizing their home insulin therapy; To offer a reliable instrument for adjusting the meal bolus of the current hybrid closed loop (HCL) systems to account for the inter-subject variability in insulin action.

The purpose of this randomized study is to assess the efficacy of a mobile application for the improvement of blood pressure and insulin resistance in people with metabolic abnormalities.

Given the data on the active ingredients of Totum-63, this research aims to evaluate the effect of its chronic consumption (24 weeks) on glucose and lipid homeostasis and especially on fasting plasma glucose in volunteers with abdominal obesity associated with impaired glucose tolerance or untreated type 2 diabetes and hypertriglyceridemia. This clinical study is designed to estimate the effect of Totum-63, active ingredient of Valedia, on several glucose and lipid homeostasis related parameters since these data are still unknown for this specific dietary supplement formula. Collected data will provide more reliable information which may be used to plan a subsequent larger main study.

The present study examined the effect of Montmorency tart cherry juice and capsules on functional and blood-based cardio-metabolic markers in humans with Metabolic Syndrome. Participants received a single bolus of Montmorency tart cherry juice, Montmorency tart cherry capsules and placebo in a random, crossover trial. Outcome variables were measured immediately pre- and up to 5 hours post-bolus. It was hypothesised that Montmorency tart cherry juice and capsules would improve cardio-metabolic markers. Furthermore, it was hypothesised that Montmorency tart cherry capsules would be more beneficial than Montmorency tart cherry juice due to increased bioavailability of phytochemicals.

A substudy of TMC114FD2HTX4004 that will perform glucose tolerance testing, adipose testing and MRI scan at baseline, 12 and 24 weeks post switch of ART medications.

During last decades, an excessive intake of sugars has been observed in westernized countries, mainly due to the consumption of sugar-rich soft drinks. Epidemiological studies have pointed out a positive correlation between the consumption of such drinks and the risk of obesity, diabetes, and cardiovascular diseases. Therefore, there is a growing trend looking for new non-caloric alternatives (sweeteners) in order to reduce the sugar content of foodstuffs without losing their sweetness and tastefulness. However, some questions regarding sweeteners have recently arisen as their effects after long-term consumption have not been fully unravelled. They could also contribute to a higher caloric intake and to disrupt the gut microbiota. Besides seeking new alternatives for the high intake of sugar-rich drinks, there is a need for increasing the consumption of fruits and vegetables among general public. Developing new products to stretch the shelf-life of fresh fruits, preserving their nutrients, and reducing the energetic content of fruit juices should also be accomplished. In this sense, lemon juice has been proposed as an interesting ingredient in the elaboration of soft drinks due to its distinctive aroma and high nutritive value. Its combination with maqui berry juices contributes to stabilize the colour and phenolic compounds that both products contain (mainly flavanones for lemon juice and anthocyanins for maqui). The beneficial effects of these vegetal foodstuffs and their phenolic substances on glucose intolerance have been reported.The aim of BEBESANO is studying the beneficial effects of sugar-free, rich-in-phytochemicals drink consumption on postprandial hyperglycaemia, in order to provide alternatives to excessive sugar intake and counteract the postprandial response linked to sugar consumption in subjects with low levels of chronic inflammation such as overweight people. Moreover, BEBESANO will shed light on the interactions of food constituents with the main pathways involved in the lipid and glucose metabolism, oxidative stress, inflammation, and hormonal regulation in overweight population.

Previous work of the investigators demonstrated the anti-obesity and anti-steatosis potential of the Amazonian fruit camu-camu (CC) in a mouse model of diet-induced obesity [1]. It was demonstrated that the prebiotic role of CC was directly linked to higher energy expenditure stimulated by the fruit since fecal transplantation from CC-treated mice to germ-free mice was sufficient to reproduce the effects. The full protection against hepatic steatosis observed in CC-treated mice is of particular importance since nonalcoholic fatty liver disease (NAFLD) is one of the most common causes of chronic liver disease. Thirty percent of adults in developed countries have excess fat accumulation in the liver, and this figure can be as high as 80% in obese subjects. NAFLD is an umbrella term encompassing simple steatosis, as well as non-alcoholic steatohepatitis which can lead to cirrhosis and hepatocellular carcinoma in up to 20% of cases. Up to now, except for lifestyle changes, no effective drug treatment are available. Previous work has suggested that CC possesses anti-inflammatory properties and could acutely reduce blood pressure and glycemia after a single intake. While CC could represent a promising treatment for obesity and fatty liver, no studies have thoroughly tested this potential in humans. Therefore, a robust clinical proof of concept study is needed to provide convincing evidence for a microbiome-based therapeutic strategy to counteract obesity and its associated metabolic disorders. The mechanism of action of CC could involve bile acid (BA) metabolism. BA are produced in the liver and metabolized in the intestine by the gut microbiota. Conversely, they can modulate gut microbial composition. BA and particularly, primary BA, are powerful regulators of metabolism. Indeed, mice treated orally with the primary BA α, β muricholic (αMCA, βMCA) and cholic acids (CA) were protected from diet-induced obesity and hepatic lipid accumulation. Interestingly, the investigators reported that administration of CC to mice increased the levels of αMCA, βMCA and CA. Primary BA are predominantly secreted conjugated to amino acids and that deconjugation rely on the microbial enzymatic machinery of gut commensals. The increased presence of the deconjugated primary BA in CC-treated mice indicate that a cluster of microbes selected by CC influence the BA pool composition. These data therefore point to an Interplay between BA and gut microbiota mediating the health effects of CC. Polyphenols and in particular procyanidins and ellagitannins in CC can also be responsible for the modulation of BA that can impact on the gut microbiota. Indeed, it has been reported that ellagitannins containing food like walnuts modulate secondary BA in humans whereas procyanidins can interact with farnesoid X receptors and alter BA recirculation to reduce hypertriglyceridemia. These effects are likely mediated by the remodeling of the microbiota by the polyphenols. In accordance with the hypothesis that the ultimate effect of CC is directly linked to a modification of the microbiota, fecal transplantation from CC-treated mice to germ-free mice was sufficient to recapitulate the lower weight gain and the higher energy expenditure seen in donor mice.

This is a research study to see if the addition of cinnamon to a provided food plan would improve insulin resistance in gynecological cancer patients. One study suggests that patients with gynecological cancers are more likely to be insulin resistant and/or have higher levels of fasting insulin. The study will be 24 weeks in length.

The purpose of the meal study is to investigate acute effects on satiety and inflammation of advanced glycation endproducts (AGE) in healthy overweight subjects. The AGE content of the meal is affected by food preparation methods: frying/grilling versus boiling/steaming.

Rationale: The investigators hypothesize that a change in dietary fat quality (an increase in unsaturated fatty acids) may modulate fuel partitioning within the type 2 diabetic muscle towards less accumulation of lipid metabolites and an improved insulin sensitivity. Objective: The contribution of dietary vs endogenous fat sources to lipid overflow in the circulation and to skeletal muscle lipid uptake and storage in obese insulin resistant subjects vs obese insulin sensitive controls. The acute effect of meals with various fatty acid composition ((high saturated (SFA) vs polyunsaturated (PUFA) vs monounsaturated (MUFA)) on skeletal muscle lipid uptake and storage, fatty acid mediated gene expression and postprandial insulin sensitivity in obese insulin resistant subjects. Study design: single-blind randomized cross-over trial Study population: obese males (35-70 years) with or without insulin resistance Intervention: 1 test meal 3 test meals with a different fatty acid composition Main study parameters/endpoints: More insight whether dietary fat quality may modulate circulating lipids and skeletal muscle fatty acids handling, and may affect oxidative capacity and lipid storage in parallel to an increased insulin sensitivity.
