Active clinical trials for "Metabolic Syndrome"

It is of major importance to refine prevention strategies in order to alleviate inflammation, insulin resistance and metabolic syndrome and it appear that improving gut health and microbiota represent a promising strategy. Cranberry-enriched diets may help prevent metabolic syndrome and its associated chronic diseases by a protective effect of gut health and microbiota. It is therefore highly relevant to test the hypothesis that a whole cranberry powder supplements (which include a mixture of polyphenols, free and fiber-associated proanthocyanidins, and fruits fibers) is associated with changes on the gut health and microbiota playing a major role in alleviating inflammation and obesity-associated metabolic disorders.

This study aimed to test the effect of a parenting intervention on metabolic syndrome in African American youth. The investigators hypothesized that a parenting intervention would produce reductions in metabolic syndrome, particularly for those families that started out high in difficulties with parenting.

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.

Health authorities recommend a reduction in added sugars from sugar-sweetened beverages (SSBs) due to risk of obesity and diabetes. As a sugar-reduction strategy, finding the ideal SSB replacement is of the utmost importance. Those who are already consuming SSBs might not easily replace it with water and therefore non-nutritive sweetened beverages (NSBs) present a sweetened alternative, though guidelines recommend water instead of NSBs as a replacement for SSBs. Recent evidence suggests that saccharine, a non-nutritive sweetener, which is not found in NSBs, might induce glucose intolerance by altering gut microbiota in humans. It is currently not known if replacing SSBs with NSBs (which contain low-calorie sweeteners other than saccharine) or water will have any effect on the human gut microbiota and any downstream diabetic risk. The investigators plan to undertake a randomized controlled cross-over trial in 75 healthy adults to assess the effect of replacing SSBs with equal amounts of NSBs or water for 4 weeks on the composition and diversity of human gut microbiota, changes in glucose tolerance and total body fat in those who regularly drink SSBs. Each participant will act as their own control receiving each of the three interventions of SSB, NSB and water for four weeks in random order, each period separated by a four-week wash-out period. All study visits will occur at the Clinical Nutrition and Risk Factor Modification Centre at St. Michael's Hospital. This study will contribute to knowledge that will inform dietary guidelines and public policy with regards to the best possible replacement for SSBs. It will also shed light on the potential mechanism of the adverse effects of NSBs and if the replacement of SSBs by NSBs or water are in fact similar with respect to their effect on gut bacteria and any downstream diabetic risk.

Fasting and postprandial hypertriglyceridemia (HTG) depends on increased production of intestinal triglyceride rich lipoproteins in patients with isolated fasting hypertriglyceridemia. The objective of this study is to compare the serum apoB48 rate after a standardized load test, among patients with isolated hypertriglyceridemia and patients with metabolic syndrome.

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.

The researchers will conduct a study for avoiding the metabolic syndrome in morbid obese patients. Thus, the aim of the present will be determine the effects of a resistance training programme (RT) in preventing or attenuating metabolic syndrome (MetS) in patients with morbid obesity. A second aim will be report the prevalence of non-responders in terms of improvements in MetS markers and other co-variables considered.

Several cytotoxic regimens are related to endothelial cell damage and vascular toxicity. Endothelial dysfunction is implicated in the pathogenesis of all known cardiovascular diseases (CVD) and closely related to the metabolic syndrome. Both CVD and diabetes contributes importantly to total mortality and to breast cancer (BC) specific mortality. In the epidemiological part of the project, the investigators will determine the prevalence and incidence of cardiovascular and metabolic morbidity/mortality in early BC patients compared to the Danish background population. In the clinical part, the investigators will study the changes of endothelial function and metabolic parameters in BC patients receiving chemotherapy. With increasing number of BC survivors, long-term consequences of curative cancer treatment should be studied. The investigators hypothesize that cytotoxic therapy worsens metabolic parameters possibly through endothelial dysfunction. If this is true, the next step will be to evaluate how strict metabolic control will affect prognosis.

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.

Type 2 diabetes mellitus (DM2) is a growing social health problem world-wide, in particular with respect to its contribution to cardiovascular disease. The progressive increase in prevalence of DM2 has reached epidemic proportion and is a major cause of morbidity and mortality in all populations around the world. Conventional stepwise treatment of DM2 generally focuses on controlling blood glucose concentration. However, the risk for side-effects associated with the use of pharmacological intervention often delays initiation of therapy, with the potential implication on worsening morbidity and mortality from complications. On the other hand, non-pharmacological intervention in the form of dietary restrictions, exercise and weight loss, is safe but often difficult to accomplish. The availability of nutrients that affect glucose and lipid metabolism would provide an important practical tool to establish early intervention in newly diagnosed DM2 and perhaps even in patients who are only "at risk" for DM2. The investigators have recently obtained preliminary data on beneficial effects of combined supplementation of lycopene and isoflavones on glucose metabolism of normoglycemic volunteers with insulin resistance. This clinical trial will explore the role of isoflavones and lycopene dietary supplementation in the improvement of glucose metabolism of patients at increased risk or with established but mild DM2. The overall hypothesis is that supplementation of laflavon, provided as a new formulation that increases bioavailability of the individual components (Laflavon CamMedica contains 7 mg of Lycopene and 50 mg of Soy Isoflavones), determines improvement in glucose tolerance and insulin resistance of patients with the metabolic syndrome and also reduces HbA1c in patients with mild DM2.
