Filter by:Main scientific question: A previous intervention with an anti-inflammatory multifunctional dietary portfolio (MFD) showed remarkable reductions in cardiometabolic (CM) risk markers compared with a well-designed control diet. The study was performed under weight maintenance conditions in healthy subjects in a 4w crossover design (Tovar et al., 2012). MFD consumption also resulted in improved cognitive performance after 4 weeks (Nilsson et al., 2013). The present project will further study the preventive potential of MFD, using its unique properties for identification of new biomarkers and to evaluate the potential role of alterations in the gut microbiota. MFD will be tested in healthy at risk subjects in a randomized parallel design in an eight-week intervention with the test or control diet, respectively, allowing for weight loss. Assessment of standard anthropometric/biochemical markers of CM risk, metabolomics analysis and appetite regulating hormone evaluation are also planned. Associations between the gut microbiota composition and measures of CM risk are also included. The project provides unique opportunities to identify mechanisms for the metabolic impact of MFD, for further exploitation in innovative food and/or dietary concepts. Central hypothesis: The CM-preventive potential of MFD may be boosted in a medium-term trial under conditions allowing for body weight reduction. Expected additional benefits may be recorded as reduced values for conventional CM-related parameters, markers of modified gut microbiota composition and specific changes in blood metabolite profiles. Objectives: - To further improve the effect of MFD on biochemical/anthropometric CM risk markers in healthy subjects by administering the diet under conditions allowing for weight reduction. - To identify MFD-related changes in the gut microbiota associated with improved CM risk markers. - To assess MFD-related modification in metabolic pathways, studied with a metabolomics approach, and to correlate them with conventional clinical outcomes, aiming to identify new markers of altered metabolic risk.
The main objectives of this study are to test the hypotheses that: 1) consumption of beverages sweetened with sucrose will increase risk factors for cardiovascular disease to a greater extent than a naturally-sweetened fruit juice such as orange juice, and 2) chronic psychological stress may augment the adverse metabolic effects of sugar intake. The study intervention consists of 2-week's consumption of 25% of energy as sugar provided either as a sucrose-sweetened beverage or naturally-sweetened orange juice.
Metabolic syndrome (MetS) is a clustering of cardiovascular risk factors characterizing central obesity, insulin resistance, dyslipidemia and high blood pressure. The concept of MetS represents the pre-cardiovascular and pre-diabetic pathologic conditions, which has been a useful tool in prognosing the development of cardiovascular disease and diabetes mellitus. Importantly, interventions applied at the pre-pathologic stage with MetS would be of great clinical and health significance in achieving better preventive and therapeutic outcomes. Yoga, a mind-body exercise, has been suggested to have beneficial effects on dyslipidemia, hypertension and diabetes. A pilot study has demonstrated the trends in the improvement of metabolic parameters in middle-aged adults with MetS but the findings are inconclusive because of the small sample size and brief yoga follow-up period (i.e., 2-month). In addition to the needs of a better designed randomized controlled trial in studying the beneficial effect of yoga in controlling MetS in middle-aged individuals, the investigation on yoga and MetS in elderly population has been lacking. This is important as the potential use of yoga as lifestyle modification in elderly individuals with MetS will result in significant reduction of the prevalence of cardiovascular disease and diabetes. Thus, this study aims to examine the efficacy of yoga exercise in improving metabolic abnormalities in middle-aged and older adults with MetS. In addition to elderly, middle-aged adults are included in the present investigation because of the idea that cardiovascular diseases and diabetes with aging can be mostly prevented by intervention at the middle-age. A randomized controlled trial with repeated measure design will be conducted to examine the effect of 1-year regular yoga training on the MetS parameters in middle-aged and older individuals who are 30-60 and 60-80 years of age, respectively. Primary outcome measures include waist circumference, systolic/diastolic blood pressure, blood glucose, triglyceride, and lipid cholesterol profile whereas secondary outcome measures include self-reported stress and depression levels. This study is anticipated to provide valuable information in exploring the therapeutic role of yoga in managing MetS. As yoga exercise is an economical regimen which can be easily and readily applied to large scale of target population, it is of hope to be practically useful to relieve the burden on cardiovascular disease and diabetes by introducing yoga lifestyle to the management of MetS.
The aim of this study is to explore the role of Canonical β-catenin/Wnt and forkhead box O (FOXO) pathways by means of investigating their target genes in coronary artery disease (CAD) pathogenesis and to examine the effects of resveratrol (RES) on these pathways in CAD patients.
Bed rest produces insulin resistance in healthy volunteers. In this study the investigators aim to investigate the effect of 8 days bed rest on the incretin effect and how alternate daily fasting affects cognitive function and the insulin resistance produced by bed rest. The subjects will be randomized to either 3 meals a day (isocaloric diet), alternate daily fasting or one meal/day every second day (25% of daily calorie need) and four meals/day every second (175% of daily calorie need). The investigators hypothesize: 1. Bed rest reduces the incretin effect 2. Alternate daily fasting improves the cognitive function (memory and concentration) compared to isocaloric diet 3. Alternate daily fasting reduces insulin resistance produced by bed rest compared to isocaloric diet
This study aims to evaluate the effects of enterolignanas of flaxseed on nutritional and inflammatory indicators in male workers of a food industry.
This study is conducted in a cohort of HIV-positive patients on first-line anti-retroviral therapy (ART) in rural health facilities in Lesotho, Southern Africa. It examines virologic treatment failure as well as chronic communicable and non-communicable comorbidities among patients on ART. The study has two phases. Phase 1 consists of a cross-sectional survey to determine prevalence of treatment failure as well as the prevalence of the following comorbidities: diabetes mellitus, arterial hypertension, dyslipidemia, depression, alcohol use disorder, hepatitis B and hepatitis C. Phase 2 is a cohort study, where patients with treatment failure or a comorbidity or both are followed-up for 12 months.
Metabolic syndrome is a condition involving elevated levels of fat in the blood, a tendency towards diabetes, hypertension, and too much fat around the abdomen (an increased waistline). Individuals with metabolic syndrome often have impaired glucose tolerance, which is a condition where blood sugar is normal when fasting (before eating), but is too high after drinking a sugary drink. This is due to an abnormality in the body's sensitivity to insulin (insulin resistance), which is due in part to an inability of the muscle to take up glucose. People with metabolic syndrome have inflammation in their fat tissue and in their blood stream, and the changes in the level of inflammatory chemicals produced by cells in your fat tissues will be studied. One possible source of the inflammation may be the bacteria in the intestine. When individuals eat fatty foods, some of the bacterial products become attached to the fat in their blood and then get directed to fat tissue. The investigators wish to determine whether individuals have an excessive amount of inflammation in their fat tissues, and whether this inflammation comes from the bacteria in their intestines. To determine this, the investigators wish to treat individuals with an antibiotic that reduces the bacteria in their intestines and in their blood, and determine whether this reduces their overall level of inflammation.
Obesity is one of the main causes of the metabolic syndrome, a condition which is becoming more common in Canada and worldwide. Metabolic syndrome is a name for a group of heart disease risk factors that occur together: obesity, diabetes, high blood pressure, and high cholesterol. These patients have a high risk of developing narrowing and blockages of blood vessels which occur when fat and cholesterol build up in the walls of blood vessels and form plaque. This is called atherosclerosis. Plaque buildup leads to stroke, heart attacks, and death. We do not understand the underlying mechanisms of the metabolic syndrome and we do not have a treatment for it. L-carnitine, a dietary supplement, has been shown to treat some components of the metabolic syndrome, but its benefit to reduce plaque in the blood vessels has never been studied. Recently there has been some controversy because a new study showed that L-carnitine could make heart disease worse in some patients. Our goal is to study whether supplementation with L-carnitine does in fact prevent or reduce buildup of plaque in blood vessels of patients with the metabolic syndrome. This novel therapy has the potential to decrease the burden of heart disease in obese and diabetic patients with the metabolic syndrome.
The Metabolic Syndrome is a high prevalence disease worldwide. About a quarter of the adult population suffers the disease. Resveratrol is a substance found in many plants, including grapes, nuts and wine, but it's also found in Polygonum cuspidatum. There is evidence that resveratrol consumption has beneficial effects on glucose and lipids metabolism, blood pressure and body weight. The aim of this study was to evaluate the effect of resveratrol on metabolic syndrome, insulin sensitivity and insulin secretion. The investigators hypothesis was that the administration of resveratrol modifies the metabolic syndrome, insulin sensitivity and insulin secretion.
