Filter by:Metabolic Syndrome (MS) is a well-known group of obesity-related metabolic disorders including insulin resistance (IR), dyslipidemia and hypertension (HTN). In addition, overweight has a causal relationship with a chronic low grade systemic inflammatory condition and increased intestinal permeability. Over the last decade, this multiplex disorder has progressively become a major worldwide public health problem, because of its association with increased risk of type 2 diabetes mellitus (DM2), atherosclerotic cardiovascular disease and all-cause mortality. Scientific evidence for measures to improve cardiometabolic and intestinal health by non-pharmaceutical means are of urgent need. Administration of the flavonoid hesperidin to those at risk may have beneficial effects on glucose / insulin metabolism, lipid metabolism, blood pressure, heart rate, pro-inflammatory and oxidative stress biomarkers and gut barrier function. Objective: To determine the 12-week effect of daily administration of hesperidin on the main cardiometabolic disorders related to MS as assessed by investigation of glucose/insulin metabolism, blood lipid profile, blood pressure, heart rate, body composition and gut barrier function in subjects at risk for MS. Study design: This is a randomized, double-blind, placebo-controlled study with parallel design. Study population: Healthy (male/female) volunteers, age 18-65, at risk for metabolic syndrome (presenting with 2 out of 5 of the components from NCEP-ATP-III criteria). Intervention: Participants will be randomly assigned to one of the intervention groups. One group will receive one daily dose of hesperidin capsules while the other group receives identical looking placebo capsules for a period of 12 weeks. The capsules will have to be ingested with a glass of water every morning just before breakfast. Main study parameters/endpoints: The primary efficacy parameter of this study is the oral glucose tolerance test (OGTT), a validated surrogate endpoint to study the β-cell function and insulin sensitivity. Secondary endpoints entail the evaluation of effects of daily administration of hesperidin on lipid profile (blood measurements), blood pressure and heart rate, body composition, low-grade inflammation biomarkers (blood measurements) and gut barrier function (blood measurements, fecal samples, urine collection).
Project title: A randomized controlled trial of whole soy diet in place of red/processed meat and high fat dairy products on metabolic features in postmenopausal women Objectives: Metabolic syndrome (MetS) is an escalating public health problem especially in postmenopausal women. Traditional whole soy foods are rich in unsaturated fats, high quality plant protein and various bioactive phytochemicals that could benefit on MetS. The aim of the study is to examine the effect of whole soy replacement diet on the features of MetS among postmenopausal women. Hypothesis to be tested: Whole soy diet in place of red or processed meat and high fat dairy products will significantly improve metabolic features. Design and subjects: This will be a 12-month randomized, single-blind, controlled trial among 208 postmenopausal women with high risk of MetS or early MetS. Study instruments: After 4 weeks' run-in, participants will be randomly allocated to either of two intervention groups, whole soy replacement group or control group, each for 6 months. Interventions: Subjects in whole soy group will be required to include 4 servings of whole soy foods (containing 25g soy protein) into their daily diet isocalorically replacing red or processed meat and high fat dairy products. Subjects in the control group will remain an usual diet. Main outcome measures: The outcome measures will include the indices of metabolic features as well as a 10-year risk for ischemic cardiovascular disease. Data analysis: The changes and %change of the metabolic features at 6- and 12-month will be compared among the two groups. Expected results: Whole soy diet substitution of high saturated fat and cholesterol rich animal products will notably decrease the risk of MetS.
The objective of the Project is to assess the effect of traditional food on the expression of micro-ribonucleic acid (miRNA), which regulate genes related to glucose metabolism. It will be a randomized experimental research. The research hypothesis is that consumption of traditional food will resolve biomarkers of glucose-related anomalies. Students of The Academic Division of Health Sciences (DACS for its initials in Spanish) will be invited to participate and they will be divided randomly in two groups. The experimental group will receive daily, five days per week, during three months, a lunch based on traditional Mesoamerican food emphasizing local produce. The experimental group will be provided an equivalent ratio of fast food from the school cafeterias. In both groups, at the start and end of the protocol, values of lipid, glucose, reactive protein C, alanine aminotransferase, and glycosylated hemoglobin profiles will be determined through spectrophotometric methods. The levels of expression of five miARN involved in regulating genes related to glucose metabolism (miR-320, miR-33a/b, miR-145, miR-335, and miR-124a) will be determined also by means of PCR amplification techniques. Statistical analyses will be based on two-way ANOVA, with a Dunnet's test procedure to find significance in measurements; significance will be set at p ≤ 0.05.
The purpose of this study is to determine whether the Chinese formula AMP-1915 has effect on Metabolic Syndrome (MS) in MS patients. Half of patients received AMP-1915, while the other half received placebo.
Legumes are generally recognized as healthy dietary components, and although beans and legumes are recommended in food guidelines in North America, guidelines vary in regards to how much and how often these foods should be consumed. Furthermore, although North American and European guidelines recommend dietary pulses for glycemic control, dietary pulses and other legumes are not specifically suggested for controlling blood pressure and maintaining heart health. To improve evidence-based guidance for legume recommendations, the investigators propose to conduct a systematic review of clinical studies to assess the effect of eating legumes in exchange for other foods on blood pressure in humans. The systematic review process allows the combining of the results from many small studies in order to arrive at a pooled estimate, similar to a weighted average, of the true effect. The investigators will be able to explore whether eating legumes has different effects in different demographics, and whether or not the effect of legumes depends on how much/often they are eaten. The findings of this proposed knowledge synthesis will help improve the health of Canadians through informing recommendations for the general public, as well as those at risk of heart disease and diabetes.
This is a Phase 2, open-label, single-arm study of the safety and tolerability of PBI-4050 800 mg daily oral administration in type 2 diabetes patients with metabolic syndrome. A total of 12 patients will initially be enrolled for study participation. A Data Safety Monitoring Board (DSMB) will continuously review data obtained from the 12 patients. When the 12 patients have completed at least one month of study treatment, the DSMB will meet and determine whether additional patients may be enrolled or the study should be stopped. If the safety is deemed acceptable to continue with the study, the study will enroll a maximum of 36 patients.
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 purpose of this study is to evaluate the effects of both chronic and acute grape ingestion in a population of men and women at higher risk for both type 2 diabetes and cardiovascular disease (metabolic syndrome).
This study is being conducted to evaluate the efficacy of TA-65, a purified extract of Astragalus root, on insulin resistance, oxidative stress, and inflammation in individuals classified with metabolic syndrome.
The main objective of this study is to investigate the role of female sex hormones in relation to insulin resistance in a controlled human experimental model of menopause and to explore whether exercise and/or hormone treatment (HT) can compensate for loss of endogenous sex hormone production by maintaining insulin sensitivity and metabolic activity at a level equivalent to what is seen in premenopausal women. Loss of ovarian function is associated with an increased incidence of metabolic disease including metabolic syndrome, type 2 diabetes and cardiovascular disease. This increased disease incidence seems to be related to changes in body composition including decreased skeletal muscle mass and increased visceral fat mass as well as decreased whole body fat oxidation and energy expenditure. Regular physical activity decreases general mortality among other things by increasing fat free mass and insulin sensitivity and hereby prevents metabolic syndrome and cardiovascular disease - conditions seen with an increased incidence after menopause and could therefore be a possible treatment. In the present study the Investigators will assess the role of sex hormones in a model of menopause where healthy women are undergoing planned bilateral oophorectomy due to risk of hereditary ovary cancer. The use of this model makes it possible to control the time point for loss of ovarian function and hereby investigate the timeframe and possible contributing factors in a strictly controlled model. 48 premenopausal women will be included in the study. The study is conducted in women who have already been offered surgical oophorectomy. The first 2 months the study will be an observational cohort study. Hereafter the patients will be allocated to one of four groups (n=12) in a randomized controlled trial, addressing the effects of 6 months of exercise with or without HT. Type of surgery has been decided before inclusion based on medical indications. The women will be offered HT according to national guidelines, but the choice is up to them. Randomization applies only to the training intervention. Firstly the Investigators aim at investigating the role of endogenous female sex hormones and HT in relation to insulin resistance, whole body fat oxidation and -energy expenditure, changes in visceral fat mass and fat free mass after oophorectomy. Secondly, the Investigators wish to study the molecular mechanisms behind the oophorectomy-induced insulin resistance with a focus on insulin signaling in skeletal muscle and fat tissue. Lastly, the investigators aim to explore whether exercise and/or HT can compensate for loss of endogenous female sex hormone production by maintaining IS and metabolic activity, hereby preventing future incidents of metabolic disease in relation to menopause. All in all, this project will contribute with new knowledge concerning the question of how endogenous female sex hormones affect insulin sensitivity and metabolic functioning and how exercise may be used as a disease preventive modality for middle-aged women.
