Active clinical trials for "Metabolic Syndrome"

This cross-over study investigates health effects of dietary intake of whole walnuts towards cardiovascular risk factors in adults under low cardiovascular risk. Investigators hypothesize that daily intake of whole nuts as a replacement meal, would improve cardiovascular risk factors, including traditional risk factors and molecular biomarkers. The participants are randomly assigned to receive either study treatment, or no treatment, and are crossed after five weeks. The study subjects are instructed to continue with their habitual diet and physical activity.

The order in which the different components of a meal are eaten may have impact on the postprandial metabolic responses to carbohydrates, fat and proteins. This study will compare blood lipids and glycemia regulation following lunches of identical composition but varying the order of intake of the different meal components.

A randomized placebo controlled trial to determine if increased dietary fiber will prevent weight gain, inhibit adiposity and reduce perceived stress levels in residents at the Waco Family Health Center as the result of changes in distal gut microbiota composition and function.

This study evaluates dietary green tea extract to improve gut health and inflammation in persons with metabolic syndrome and healthy adults. Participants will complete two phases of intervention in random order in which they will consume green tea extract or placebo for one month and then switch to the opposite treatment for an additional month.

Introduction: The consumption of non-nutritive sweeteners (NNS) has been increasing in recent years, as an alternative to replace sugars and reduce the additional intake of carbohydrates, with the idea of reducing the risk of developing obesity, metabolic syndrome, and diabetes. However, recent evidence shows that their chronic intake induces endocrine alterations that may have an important contribution to the increase in body weight. Few studies have explored the acute effects of NNS beverage consumption on endocrine response, and to date, the evidence has been inconsistent regarding post-drinking effects and potential health risks. Objective: To evaluate the effect of 3 different types of cola beverages, compared with carbonated water, on glucose, insulin, glucagon, and appetite-regulating hormones during the first 120 minutes after ingestion. Methods: A triple-blind, randomized crossover controlled trial was carried out in which 20 healthy adult individuals (10 men and 10 women) were included. With a washout period of one week (7 days) and fasting for 8 hours, each participant consumed orally 355 mL of carbonated water (CAR), and the 3 different cola beverages sweetened with sucrose (SUC), aspartame/acesulfame K (ASP), and sucrose/stevia (STE), in its commercial presentation. The serum levels of glucose, insulin, glucagon, GLP-1, GIP, PYY, leptin, pancreatic polypeptide, and ghrelin were determined during the administration of each one of the drinks before the intake of the drink and later at 30, 60, 90, and 120 minutes. Statistical analysis: A descriptive analysis of the variables was performed. The global response of glucose, insulin and appetite-regulating hormones was estimated and the Area Under the Curve (AUC) was obtained using a trapezoidal model and analyzed for each outcome by one-factor ANOVA. An ANOVA for repeated measures was performed considering treatment and time as factors, and comparisons were made with the carbonated water as a control using the Bonferroni test. P values less than 0.05 were considered statistically significant. Ethical considerations: Our institution's Research, Bioethics, and Biosafety committees authorized the project. All the participants were informed about the objective, the procedures, and the possible adverse effects considered within the study, and they signed the informed consent before the start of the interventions.

The goal of this clinical trial is to provide evidence, through an extreme exercise prescription (1,144 km of road cycling on seven consecutive days), that weight loss is not the appropriate outcome to evaluate the effects of exercise on abdominal adiposity and ectopic fat depots (e.g. liver fat and epi/pericardial fat) in eleven recreational middle-aged male cyclists (aged 50 to 66 years) without symptoms of cardiovascular disease. The main questions it aims to answer are: If energy intake is substantially increased to compensate energy expenditure and prevent weight loss following an extreme exercise prescription, will significant changes in body composition and body fat distribution be observed? Will these changes translate into improvements in the cardiometabolic health profile even in the absence of weight loss? Participants will be asked to partake in several evaluations: fasting plasma lipoprotein-lipid profile and inflammation markers, glycated hemoglobin, cardiorespiratory fitness, submaximal exercise test including measurement of energy expenditure, resting and exercise blood pressure and heart rate, evaluation of regional adiposity, liver fat content, epi/pericardial fat, nutritional quality, and level of physical activity. After baseline evaluations, participants will be asked to alternately bike 208 km and 104 km per day on a pre-specified course for seven consecutive days. They will be accompanied during each of the seven bike rides by research professionals in a recreational vehicle. Participants' weight, body composition and waist circumference will be measured under standardized conditions in the morning after an overnight fast and after the exercise. Their heart rate will be continuously monitored, and participants will wear accelerometers to estimate their daily exercise-related energy expenditure. Foods and fluids will be provided to participants and recorded. At the end of the 1,144 km/ 7-days bike ride, baseline evaluations will be repeated with the exception of the maximal exercise treadmill test, nutritional quality, and level of physical activity. To facilitate the conduct of the protocol, the eleven participants will be evaluated and followed in two distinct groups.

The estrogenic deficit characteristic of the climacteric stage is accompanied by a high incidence of health problems, such as the presence of Metabolic Syndrome risk factors that contribute to the increase of cardiovascular diseases. Objective: To determine the effect of a nursing intervention based on self-care aimed at improving the control of two metabolic syndrome risk factors (abdominal obesity and arterial hypertension) and health-related quality of life in climacteric women. Material and methods: Quasi-experimental study, non-equivalent control group design with women between 40 and 59 years old who present two risk factors of the Metabolic Syndrome (abdominal obesity and arterial hypertension) from two type C Health Centers of District 17D03 of Quito, Ecuador. Among one of the conceptual hypotheses, the researchers have Conceptual hypothesis 1: Climacteric women of the experimental group after the intervention of Nursing based on self-care improve two risk factors of MS with respect to those of the comparison group. A sample of 40 women was selected for experimental group and 40 for comparison group. Instruments and measurements: Abdominal Circumference, Blood Pressure, Menopause Rating Scale, International Physical Activity Questionnaire (IPAQ). Women in both groups received the usual care and those in the experimental group received a Nursing Intervention with technological support that included individual face-to-face nursing counseling, group education and physical activity sessions through a virtual platform for 12 weeks. Ethical requirements were considered. Expected results: It is expected that after the Nursing Intervention based on self-care the women of the experimental group will decrease the parameters of abdominal circumference, blood pressure and improve health-related quality of life.

Rationale: Subjects with the metabolic syndrome have an increased risk of developing cardiovascular disease and a twofold risk of developing hypertension. A functional food ingredient with the ability to improve arterial stiffness, microcirculation and/or the ability to reduce blood pressure could potentially contribute to the delay or prevention of a range of cardiovascular diseases and could provide additional complimentary alternatives to pharmacological and lifestyle based interventions in the maintenance of cardiovascular health. Objective: To assess the acute (2h) and short term (2 days and 4 week) effects of daily administration of 5g of NWT03 (an egg-protein hydrolysate) on carotid-radial Pulse Wave Velocity (cr-PWV). Secondary objectives are to assess its effects on carotid-femoral PWV, characteristics of microcirculation, systolic and diastolic blood pressure, lipid and lipoprotein metabolism, glucose metabolism and incretins. Study design: Investigators propose to carry out a randomized, double-blind, placebo controlled crossover study. Study population: Eligible subjects will be male or female, non-smokers between 18-75 years of age and will be otherwise healthy, but meeting at least three criteria of the Metabolic Syndrome (MetS). It is estimated that 80 otherwise healthy subjects with MetS will be randomised, to result in a minimum of 72 evaluable subjects (drop out maximal 10%) at the end of the study. Intervention: Subjects will be randomly allocated to receive 5g of NWT-03 and placebo, once daily, on separate occasions, for a period of 4 weeks and with a washout period between the two interventions of typically 4 weeks. However, this period may be shortened by 2 weeks or extended by 8 weeks, depending on the availability of the subject. Total study duration will be 10 - 16 weeks, depending on the duration of the washout period. Main study parameters/endpoints: Measurements will be performed at the start and end of each 4-week intervention period. Effects of NWT-03 supplementation will be calculated as the absolute differences between values obtained at each period. The main study endpoint is the change in cr-PWV. Nature and extent of the burden and risks associated with participation, benefit and group relatedness: Before the study starts, subjects will be screened to determine eligibility during a screening visit. During this visit, body weight, height, waist circumference and blood pressure will be measured and a venous blood sample (10 mL) will be collected. During the study, subjects will receive NWT-03 and placebo powders in random order and are asked to consume it on a daily basis. At visits 2, 3, 4, 5, 6 and 7 (days 0, 2, 27, 56, 58 and 83 of the study), cr-PWV, cf-PWV and office blood pressure will be recorded. A fundus photograph and a blood sample (20mL) will be taken in fasting condition. 2 hours after intake of the designated study product cr-PWV, cf-PWV and office blood pressure will again be measured and another fundus photograph will be taken. Additionally, a blood sample (20 mL) will be collected. Thus, in total 270 mL blood will be drawn. A pregnancy test will be taken in females of childbearing potential at visits 2 and 5. Subjects will be asked to fill out a food frequency questionnaire and to provide a spot urine sample at visits 4 and 7. Furthermore, subjects will be asked to keep a study diary throughout the duration of the study. Total time investment for the subjects will be approximately 19 hours. Apart from bruises or hematoma, rarely induced by blood sampling, no risks are associated with participation in this study.

The objective of the study is to investigate effects of inorganic sodium nitrite on the cardiometabolic and hormonal disturbances observed in a targeted population of overweight/obese adults with metabolic syndrome and hypertension, at risk for insulin resistance and endothelial dysfunction.

Potato is one of the world's most popular foods and is widely accepted as a staple food. The objective of this study is to determine the effect of consuming instant mashed potatoes with and without fat on glycemic response, subjective appetite and food intake. It is hypothesized that mashed potato with added fat (as it is usually consumed) will result in lower glycaemic response and subjective appetite, and reduced subsequent food intake.
