Filter by:Though medical treatment has been effective in the treatment of cardiometabolic diseases (including coronary atherosclerosis and diabetes mellitus), the incidence of these disorders continues to be high. Many reasons are responsible, but lifestyle changes, including an increased prevalence of obesity and the metabolic syndrome, are significant for this cause. Diagnosis and treatment of obese patients with hypertension requires that health care providers address the issues of hypertension, glucose intolerance, body weight and dyslipidemia. A sedentary lifestyle and poor cardiorespiratory fitness are not only associated with the (cardio) metabolic syndrome but could actually be considered features of the metabolic syndrome. These issues are significant in the health of certain individuals, who experience greater difficulty in treated BP control, experience increased hypertensive and diabetic complications, and have higher levels of obesity. In this study, the investigators will evaluate the efficacy of the nutritional supplements berberine, alpha-lipoic acid, and picrorhiza (CAR-191) when consumed 30 minutes before meals, on appetite suppression, body composition and weight control. Additionally, the investigators will evaluate the effects of this combination of nutraceuticals on the mechanistic effects of oxidation, inflammation, and vascular function in a high-risk population with the metabolic syndrome. Primary Objective To assess the comparative effect of a combination (known as CAR-191) of berberine (200 mg), alpha-lipoic acid (150 mg), and picrorhiza (100 mg) three times a day, compared to placebo three times a day, on parameters relate to appetite suppression, weight control and body composition in a high risk population with the metabolic syndrome. Secondary Co-objectives To evaluate the effects of CAR-191 versus placebo on changes in: - Endothelial function using noninvasive brachial artery reactivity (BAR) ultrasound - Biomarkers including IL-6, HOMA-IR, HbA1C, hsCRP, adiponectin, plasma/urine isoprostanes, PAI-1, TNFα-II, aldosterone, and glutathione redox ratio - Urinary protein excretion - Clinical chemistry including plasma glucose, blood urea nitrogen, creatinine, total bilirubin, uric acid, transaminases (SGOT/AST, SGPT/ALT), alkaline phosphatase, C-reactive protein, and lipoproteins
Soy protein has a high biological value, and contains several potential health-related nutritional factors, i.e. its amino acids pattern, biological active peptides and non-protein compounds such as isoflavones. In the field of obesity and blood lipids soy protein is well-studied and appreciated; it improves circulating blood lipids and is associated with weight reduction. The effect of soy on insulin resistance, glucose homeostasis and the metabolic syndrome is less frequently studied. However, several molecular mechanisms of action of soy protein make it a promising approach.
Glypican4, CTRP3, CTRP5 are emerging novel adipokines mediating obesity and inflammation related disorders. RBP4 and adiponectin are well known important adipokines. Therefore, we examine the circulating levels of theses adipokines in the subjects with or without metabolic syndrome. Furthermore, we tried to clarify the effect of exercise on the circulating these adipokines.
High intake of insoluble fiber is strongly associated with a reduced incidence of diabetes and cardiovascular events in prospective observation studies. Our primary objective is to compare a life style diabetes prevention program(PRAEDIAS) with and without added insoluble fibers in its effectiveness to prevent incident diabetes type 2 in high risk individuals with impaired glucose tolerance. Subjects with IGT not willing to participate in the intervention will be used as independent controls. Secondary aims are to identify mechanisms of action with regard to body composition, anti-inflammatory and metabolic effects of fibers. We propose a randomized, prospective intervention study. The results will be of general relevance for guidance of fiber intake in the population and will help the food industry to design healthy high fiber foods. Fiber can be added at low cost to numerous foods. Increased fiber intake may therefore provide a simple non-cognitive prevention strategy effective at the population level.
An increased body mass impairs vascular function (VF), an important characteristic of subjects suffering from type 2 diabetes and a risk marker for cardiovascular diseases. However, a wide variety of in vivo VF markers exists each measuring different aspects of VF. Each of these markers addresses a different aspect of the vasculature. Studies comparing under standardized conditions the differences and relationships of the many different VF measurements in lean and abdominally overweight / obese subjects are missing. Also, there is a great need to know which of these markers are sensitive to dietary challenges. Therefore, it is imperative to conduct an extensive study on dietary effects and interrelationships of a broad spectrum of VF measurements and plasma biomarkers in lean and overweight / obese subjects. Focus will be on FMD, a well accepted biomarker for cardiovascular disease. The investigators propose to examine, in a two-way parallel-randomized human intervention study, the effects of weight-loss in abdominally overweight / obese men on VF markers and plasma biomarkers related to low-grade inflammation and vascular activity during the fasting and both the postprandial and hyperinsulinemic state. Furthermore, differences - and relations between - VF measurements and plasma biomarkers will be compared cross-sectionally between lean and abdominally overweight / obese male subjects.
Inflammation has been known to be a pivotal pathogenic mechanism of obesity-related disorders such as type 2 diabetes, metabolic syndrome and atherosclerosis. Adipose tissue functions as a major endocrine organ by adipokine mediated modulation of a number of signaling cascades in target tissues, that has pro-inflammatory or anti-inflammatory activities. Progranulin and CTRP3 are recently discovered novel adipokines. Therefore, the investigators tried to clarify the clinical meaning of these two adipokines in the subjects with or without metabolic syndrome
Since the introduction of antiretroviral therapy life expectancy of HIV-infected persons is rising. Different cohorts are observing an increased risk for cardiovascular diseases in this aging HIV-infected population. Traditional cardiovascular risk factors like smoking are more frequent in HIV-infected persons. For example chronic inflammation due to HIV-infection and metabolic disorders also caused by some antiretroviral substances as special non-traditional risk factors in HIV-infected persons can influence the development of cardiovascular diseases additionally. Therefore new research focus in special risk profile associated with HIV-infection or antiretroviral treatment and prevention for HIV-infected patients is developing. This present study is an ongoing prospective regional multicenter trial that was conducted to analyse the incidence, prevalence and clinical course of cardiovacular disorders in HIV-infected out-patients. Cardiac disorders witch are associated with HIV are pericarditis, pleural effusion, pulmonary hypertension, dilated cardiomyopathy, heart failure, myocarditis, bacterial endocarditis and heart valve disorders. In addition to previously stated disorders of the heart, the premature atherosclerosis of coronary arteries, a further even more important disease of the heart in this patient population, went into the focus of most HIV-researchers and physicians.
The 15-25% of the population of developed countries suffers for metabolic syndrome. It is associated with a 2-4 fold increase in cardiovascular morbility and mortality and with a 5- 9 fold increase in developing type II diabetes. MS prevalence increases after the onset of menopause, because of estrogen deficiency. It is still not clear if menopause itself increases the risk of cardiovascular diseases in al women or only in those that develop MS. Many MS patients that show slight modification in cardiovascular and metabolic parameters are not generally pharmacologically treated since diabetes or alteration in the lipid profile are not evidenced. In this respect it is of importance to develop new therapeutic strategies to prevent and treat MS. Genistein (4,5,7-trihydroxyisoflavone), shown a potentially preventive role on the cardiovascular apparatus in post-menopausal women, may be termed as selective ER modulator (SERM), since it reveals both ER-alpha full agonist and ER-beta partial agonist activity.
The present study investigates the effects of recreational soccer in type 2 diabetic men in regard to muscular, cardiovascular adaptations and glycaemic control. 12 men participate in 6 month structured recreational soccer training and 10 men act as control with no change in lifestyle. Testing consisting of fasting blood samples, muscle biopsies, Dexa-scans, echocardiography, maximal oxygen consumption, Yo-Yo interval test, bloodpressure, Resting heart rate, and endothelial function (Itamar, Endopat)will be performed at baseline, after 12 and 24 weeks, respectively. The study examines the hypothesis that the high-intensity aerobic work profile combined with a high anaerobic turnover from the nature of soccer (accelerations, decelerations, turns, sudden stops) will improve glycaemic control, muscle and cardiac function and taken together will improve the overall health profile in type 2 diabetic men
Obstructive Sleep Apnea (OSA) is commonly associated with factors that increase cardiovascular risk, including Metabolic Syndrome (MS). There is a lack of well-controlled clinical studies investigating the independent effects of OSA in the development of cardiovascular disease, especially evaluating jointly mechanisms involved in these disorders such as inflammatory response, oxidative stress and vascular changes. The investigators hypothesized that in the absence of MetS, the mechanisms involved on cardiovascular consequences in OSA patients would be less important. The purpose of this study is to analyze the effects of OSA in the absence of MS, on inflammatory, oxidative stress and vascular markers; to verify the influence of excessive daytime sleepiness (EDS) on the same parameters; and additionally verify the effects of nasal continuous positive airway pressure (nCPAP)in theses parameters.
