Active clinical trials for "Metabolic Syndrome"

The purpose of this study is to determine the effect of various foods and/or food substances such as fats or proteins on the blood glucose and insulin concentrations in people with and without type 2 diabetes.

A number of studies have shown that short duration, high intensity interval training can improve health-related outcomes, such as insulin sensitivity and cardiorespiratory fitness. However, these often use specialized equipment, such as cycle ergometers, which makes it difficult to roll these interventions out for wide-scale use in the general population. This study aims evaluate the effects of a high intensity shuttle running intervention on insulin sensitivity, fitness and related cardiometabolic risk factors in men who are currently inactive. Participants will be randomized into intervention (4 weeks of shuttle running) and control groups. We hypothesize that the shuttle running programme will result in improved insulin sensitivity, fitness and increased fat oxidation at rest compared with the control group.

In Spain, obesity epidemic is one of the leading contributors of chronic disease and disability. Obesity is associated with higher morbidity and all-cause mortality risk especially when fat is stored in the abdominal area (i.e., increased visceral adipose tissue, VAT). Although current approaches such as energy restriction may be effective at reducing body fat and improving cardiometabolic health, their long-term adherences are limited. Time-restricted eating (TRE; e.g., 8 hours eating: 16 hours fasting on a daily basis) is a recently emerged intermittent fasting approach with promising cardiovascular benefits. Results from pioneering pilot studies in humans are promising and suggest that simply reducing the eating time window from ≥12 to ≤8-10 hours/day improves cardiometabolic health. However, currently, there is no consensus regarding whether the TRE eating window should be aligned to the early or middle to late part of the day. The EXTREME study will investigate the efficacy and feasibility of three different 8 hours TRE schedules (i.e., early, late and self-selected) over 12 weeks on VAT (main outcome) and cardiometabolic risk factors (secondary outcomes) in adults with overweight/obesity and abdominal obesity. The final goal of the EXTREME study is to demonstrate the health benefits of a novel and pragmatic intervention for the treatment of obesity and related cardiometabolic risk factors; an approach readily adaptable to real-world practice settings, easy for clinicians to deliver, and intuitive for patients to implement and maintain in their lives.

The study will be conducted on individuals with Metabolic Syndrome. There are many studies showing that aerobic exercise provides significant improvements in waist circumference, fasting glucose, high-density lipoprotein cholesterol (HDL-C), Triglyceride (TG), systolic and diastolic blood pressure (SBP-DBP), and cardiorespiratory fitness on METS parameters. However, although the beneficial effects of physical activity are known, only half of the population adheres to the 150 minutes of moderate-intensity physical activity per week recommendation. High-intensity interval training (HIIT) is a type of training that uses near-maximal intensities in short-term sessions. HIIT has been used to improve compliance because it requires less time to treat patients with cardiometabolic disease. Compared to continuous aerobic exercise, this type of training has been shown to be an effective alternative for improving maximum oxygen consumption (VO2 max), blood pressure, heart function, glucose and lipid metabolism, and markers of oxidative stress and inflammation. In the literature, HIIT has been studied in patients with METS and has been shown to be effective. In addition, a study showed that seven-day respiratory muscle training was also effective on METS parameters, but there is no study showing the long-term effects of respiratory muscle training in this patient group. Therefore, in our study, researchers aimed to show the effects of respiratory muscle training given with HIIT on METS parameters.

Non-alcoholic fatty liver disease (NAFLD) occurs when excess fat is deposited in the liver. Almost all patients also have obesity and insulin resistance (the inability of the body to effectively use insulin). Obesity and NAFLD are intricately intertwined and are increasing in incidence. While weight loss is the most effective therapy for NAFLD, the investigators' efforts are failing and in the next generation it will become the most common cause of liver failure in Canada. Recently, researchers have focused on the potential use of altering the composition of bacteria in the gut (microbiome) to alter absorption of energy from food, deposition of fat and resistance to insulin. This study will determine if transplantation of bacteria from the stool of a healthy volunteer into an individual with metabolic syndrome and NAFLD (i.e. fecal microbiota transplant/FMT) can alter insulin resistance and reduce the amount of fat deposited in the liver. FMT is being studied to treat several clinical conditions and is now standard of care for the treatment of refractory Clostridium difficile infection. Investigators are proposing a randomized controlled pilot study of FMT in 21 patients to determine the feasibility and to inform us of changes needed for a larger study.

The present study aimed to determine the effects of 16 weeks of aerobic interval training on quality of life and a set of clinical biomarkers.

Obesity and the metabolic syndrome (MetS) are rapidly growing problems. Individuals with the MetS are at risk for not only future chronic diseases, but they have a higher prevalence of neuropathy, including cardiac autonomic neuropathy, and have a higher incidence of falls. Currently there are no effective therapies to prevent or reverse the neuropathy seen in the MetS or to reduced the fall risk in this population. This research project will determine if a tailored balance exercise program will have functional benefits and result in a reduced fall risk in the growing population of patients with the MetS and neuropathy.

The purpose of this study is the evaluation of the effects in obese patients with metabolic syndrome on the composition of the intestinal microbiota, markers of the syndrome (hypertension, dyslipidemia, inflammation biomarkers, risk cardiovascular and hepatic steatosis) and other possible metabolites involved.

Investigators planed to conduct a randomized, controlled, crossover trial to examine the effects of daily walnuts intake among Korean subjects with metabolic syndrome. Primary objective of this study was to investigate the effects of daily walnut intake on changes of metabolic syndrome indices in Koreans with metabolic syndrome age over 30 years old. This study was consisted of four periods: run-in, first intervention, wash-out, and second intervention phases. As 16 weeks of first intervention period began after the run-in phase, the subjects were randomly assigned into one of two groups: walnut group and control group. Participants in walnut group consumed 45 grams of walnuts on a daily basis and participants in control group were provided iso-caloric white bread for first 16 weeks. After the first intervention and wash-out period (6 weeks), second intervention which is crossover of first intervention was started during the next 16 weeks. Anthropometric measurements and biochemical analyses were done at the beginning and the end of each intervention (0, 16, 22, and 38 weeks of trial). Habitual diet was randomly observed using 3-day diet record once during each phase. Investigators expected to evaluate 1)effects of walnut ingestion on reverting metabolic syndrome to normal status especially by reducing waist circumference and improving serum levels of triglyceride and high-density lipoprotein, 2)beneficial effects of daily walnut consumption on changes of body composition in the subjects with metabolic syndrome, and 3)regulatory effects of daily walnut intake on inflammatory markers and diabetic markers.

The benzoic acid derivatives sodium and potassium benzoate are preservatives that are commonly added to food and beverages to inhibit microbial growth and prevent spoilage. In the US the major source of benzoate intake is beverages. Studies have shown that piglets or chicks fed low levels of benzoic acid have greater feed efficiency and gain more weight than control fed animals. It has also been shown that benzoic acid inhibits the release of a key metabolic hormone, leptin, from isolated adipocytes (fat cells). Inadequate leptin levels result in increased appetite, decreased metabolic rate, weight gain, insulin resistance and increased diabetes risk. The primary aim of the proposed research is to directly determine if benzoate consumption in human volunteers results in lower levels of leptin, decreased metabolic rate and increased insulin resistance. If so this would implicate benzoic acid as an obesogen and would help inform more effective approaches to obesity prevention and treatment. A secondary aim of the study is to establish a connection between benzoate exposure and biomarkers in urine that can be used to help treat obese patients.
