Filter by:The purpose of this survey is designed to investigate the treatment status of hypertensive patient with metabolic syndrome-related risk factors treated with candesartan cilexetil tablets (Blopress Tablets), as well as to assess relationships between risk factors (example, visceral fat accumulation) and the incidence of cerebrovascular/cardiovascular events in an exploratory manner.
The hypothesis of this study is that the daily consumption of 480 ml tart cherry juice for twelve weeks will improve blood pressure and arterial stiffness by improving endothelial-mediated vasodilation and vascular sympathetic activity and favorably altering biochemical markers associated with cardiovascular risk. 28 men and women between the ages of 20 and 40 who have three of the five features of metabolic syndrome as defined by the Adult Treatment Panel III will be included in the study. After a two-week run-in phase, eligible men and women will be randomly assigned to one of two treatment groups: 1) 480 ml tart cherry juice or 2) 480 ml control drink daily for twelve weeks. After an initial telephone screening, all participants will be requested to report to the study site for their first visit. On the first visit (screening), participants will be provided with verbal and written explanation of the project. They will then be asked to sign an informed consent form, followed by measuring waist circumference, resting brachial blood pressure, fasting serum triglycerides, high density lipoprotein cholesterol, and glucose levels to confirm metabolic syndrome. Baseline assessments will be performed for medical history, medication use, dietary intake, and physical activity. Qualified participants will be scheduled for their second visit two weeks later (actual baseline data collection) and randomly assigned to their treatment group. On the second (baseline) visit between the hours of 7-10 A.M., blood pressure and vascular function will be measured followed by blood draw. Anthropometrics will be measured. Participants will be provided with their assigned treatment and will receive standard instructions on how to fill out daily diaries for their treatment, and for food and physical activity records. Blood pressure, vascular function, blood draw, and anthropometric, body composition, diet, and physical activity assessments will be repeated at 6- (third visit), and 12-week (final visit) intervals. All cardiovascular measurements will be performed between 7:00 to 10:00 A.M., in a quiet temperature-controlled room in the supine position after an overnight fast and 12 hours after the abstinence of caffeine and/or 24 hours after the last bout of moderate to heavy physical activity.
Magnesium is an essential mineral found in many foods; rich sources include whole grains, green leafy vegetables, coffee, and legumes. Magnesium is a critical cofactor in >300 enzymatic reactions, including those related to energy metabolism. Reduced magnesium intake and serum concentrations have been detected, both cross-sectionally and prospectively,in type 2 diabetes and insulin resistance, hypertension, dyslipidemia, and cardiovascular diseases. Different studies have reported inadequate magnesium intake and low serum magnesium concentrations may correlated also with metabolic syndrome, defined as a cluster of metabolic disorders including obesity, hypertension, dyslipidemia and impaired glucose tolerance or diabetes mellitus. Previous studies on this subject, however, reported contradicting results. Some investigations reported inadequate magnesium intake and low serum magnesium concentrations while others did not. To our knowledge, the epidemiological evidence on the relation between dietary magnesium intake and risk of metabolic syndrome has not yet been summarized.Therefore, the investigators will perform a systematic review and dose-response meta-analysis to assess the association between dietary and circulating magnesium level and risk of metabolic syndrome.
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.
Coleus forskohlii extract contains the bioactive compound, forskolin. Preliminary studies have shown that forskolin can increase fat metabolism thus reduce fat accumulation in both animals and humans. It has been suggested that forskolin may also suppress appetite thus reduce energy intake and results in weight loss. This study will evaluate the appetite suppressant properties of Coleus forskohlii extract. In addition the effect on central obesity and risk factors of metabolic syndrome will also be investigated.
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.
Introduction: Overall, 10 - 15% of couples seek specialist help once in their lives when a spontaneous pregnancy does not occur. These couples are defined subfertile when there is at least one year of unprotected intercourse without conceiving. Subfertility can have different causes which can be diagnosed with a basic fertility work-up. Unfortunately, the subfertility in 25% of the couples still remains unexplained. Hypothesis: The investigators hypothesize that cardio-metabolic and hemodynamic abnormalities reducing cardiovascular reserves relate to circulatory redistribution at the expense of uterine perfusion and with it women's fertility. This could especially be important in the subgroups with an unexplained subfertility and a decreased ovarian reserve. Interventions to improve these abnormalities could lead to better results in fertility treatment, better obstetric outcome and reduced lifelong health risks. Objective: The investigators want to examine specific cardio-metabolic and cardiovascular parameters in women of subfertile couples. The investigators want to evaluate the prevalence of metabolic syndrome in all women who are assessed for subfertility compared to healthy parous women. Furthermore in the women with an unexplained subfertility or with (signs of) a decreased ovarian reserve the cardiovascular profile will be studied consisting of the uterine artery pulsatility index (PI) as measure of uterine perfusion, the plasma volume as measure of venous reserve capacity, the intima media thickness of the carotid arteries as proxy of chronic strain and the endothelial function, measured by flow mediated dilatation (FMD) of the brachial artery. Study design: Cross-sectional Study population: The study group consists of subfertile women between 18 and 41 years who visit the fertility clinic in the Maastricht University Medical Centre with a primary or secondary subfertility. Women with an unexplained subfertility or with (signs of) a decreased ovarian reserve are evaluated for their cardiovascular profile. The control group consists of women with a history of an uneventful spontaneous pregnancy. Main study parameters: 1. Prevalence of metabolic syndrome in subfertile women 2. The cardiovascular profile, in women with an unexplained subfertility or with (signs of) a decreased ovarian reserve, consisting of: - The uterine artery pulsatility index - The plasma volume - The intima media thickness (IMT) - The endothelial function of the vascular system (FMD)
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
