Filter by:Mate or yerba-mate (Ilex paraguariensis A.St.-Hil.) is a native plant from South America highly consumed in this region. Different traditional products (mate, mate tea, chimarrao, tereré) are obtained from the yerba-mate leaves and consumed as herbal tea. Mate is a rich source of bioactive phenolic compounds, mainly caffeoylquinic acids. The richness of different mono- and dicaffeoylquinic acids is a peculiarity of mate derived products. However, in contrast to other plant-based beverages rich in polyphenols like tea or coffee, the research and the industry have yet little explored the potential interest of mate product to promote human health. There has been a growing interest to the development of healthier foods to face the burden of cardiovascular diseases (CVD), especially those naturally rich in bioactive phenolic compounds with protective effects against the development of chronic diseases. Different in vitro and animals studies associate the mate consumption with cardiovascular protection mechanisms. Consistent information about this activity and the long-term consumption effects in humans are scarce. The aim of this study is to assess through a randomized controlled trial the impact of chronic intake of mate on intermediate biomarkers of cardiovascular health in humans and to identify possible involved nutrigenomic mechanisms.
The MADIT S-ICD trial was designed to evaluate if subjects with a prior myocardial infarction, diabetes mellitus and a relatively preserved ejection fraction of 36-50% will have a survival benefit from receiving a subcutaneous implantable cardioverter defibrillator (S-ICD) when compared to those receiving conventional medical therapy. The trial enrollment was stopped in 2018 due to lower than expected enrollment, all subjects enrolled at that time were followed for approximately 5 years.
The present study will assess whether the beneficial effects of a market moderate-alcohol drinking in the form of white wine in humans could be derived from the endogenous formation of hydroxytyrosol (also known DOPET), a potent dietary anti-inflammatory and antioxidant molecule.
A Mediterranean dietary pattern emphasizing an abundance of plant-based foods including nuts, moderate intakes of fish, poultry and low-fat dairy products, and use of extra virgin olive oil as the main source of fat has been associated with reduced risk of cardiovascular disease (CVD), and such a pattern has been advocated by the 2015 U.S. Dietary Guidelines Advisory Committee. The strongest experimental support for this recommendation derives from the success of the recent PREDIMED CVD outcomes trial, and studies indicating that a Mediterranean-style diet improves lipoprotein and oxidative markers of cardiovascular disease risk in comparison to either low-fat or Western dietary patterns. However, in none of these studies were comparisons made between the effects of Mediterranean-style diets with low-/nonfat vs. full-fat dairy foods. The overall objective of the present proposal is to determine whether the inclusion of full-fat rather than low- and nonfat dairy foods in a Mediterranean dietary pattern based on that used in the PREDIMED study results in similar improvements in biomarkers of CVD risk. Specifically, we will test the hypotheses that 1) a standard Mediterranean diet will lower LDL-C and apoB compared to a Western diet; 2) modification of the Mediterranean diet by replacing low-fat dairy products with high-fat dairy (3 servings/day; high-dairy fat Mediterranean diet) will not significantly increase LDL-C and apoB but may raise large buoyant LDL particles compared with a standard Mediterranean diet; and 3) the high dairy fat and standard Mediterranean diets will result in comparable reductions in levels of inflammatory markers and oxidized LDL, and improvements in endothelial function compared to a Western diet.
Statins are known to cause rare but serious side effects such as rhabdomyolysis (breakdown of muscle tissue) but many patients stop taking statins due to less severe symptoms, such as muscle pain or fatigue. This study aims to determine whether symptoms occurring during statin use are caused by statins. The trial will compare patient-reported side effects of statins (20mg atorvastatin) vs. placebo. Patients will be randomized to alternating treatment blocks of either statin or placebo split into six two-month treatment periods. At the end of each period, patients will be asked to self-report side effects using a website or mobile app.
Purpose and aims Tailored internet-based cognitive behavioural therapy (I-CBT) is a new innovative and person-centred method that is promising that may be used to decrease depression in patients with cardiovascular disease (CVD). In patients with CVD, depressive symptoms is a common co-morbidity leading to decreased wellbeing, and increased morbidity and mortality. Depressive symptoms are both underdiagnosed and undertreated in CVD patients. Earlier studies have demonstrated the efficiency of cognitive behavioural therapy (CBT) for many psychiatric conditions, but few studies have evaluated CBT in patients with CVD. The overall purpose of this study is to evaluate the effects of the tailored I-CBT program on reducing depressive symptoms and other patient reported outcomes in patients with cardiovascular disease (CVD) and to explore factors related to implementation of the I-CBT program in clinical cardiac care. The primary aim: -To evaluate the effects of the tailored I-CBT depression program on depressive symptoms. Secondary aims: - To evaluate effects on quality of life´, sleep and anxiety - To evaluate factors that can influence the I-CBT programs effect on depressive symptoms. - To gain knowledge about the I-CBT program, as perceived by patients and health care professionals. - To explore facilitators and barriers to the implementation of the I-CBT program in clinical practice from the perspectives of patients, health care professionals and policymakers.
The purpose of this study is to demonstrate the feasibility and effectiveness of anticoagulation self-monitoring coupled with an educational intervention in a minority underserved population.
Countries throughout the world are facing a growing non-communicable disease (NCD) burden. In developing countries, medicines to treat NCDs are often difficult to access or too expensive for many households. Novartis/Sandoz has recently launched Novartis Access, an initiative to subsidize a basket of NCD medicines sold to purchasers in program countries and delivered through the public and non-profit health sectors. This study will evaluate the impact of Novartis Access on the availability and price of NCD medicines at health facilities and households in Kenya, the first country to receive the program.
Cardiovascular disease (CVD) is the leading cause of death in developed nations and a major health issue in Veterans. Despite a number of different treatments, cardiovascular disease remains a major health burden, thus further treatments are needed. Individuals with obesity and/or diabetes are at particularly high risk for cardiovascular disease, and research suggests that elevated levels of serum amyloid A (SAA) may contribute to cardiovascular disease, particularly atherosclerosis. In preliminary studies in both mouse and human the investigators have identified that SAA appears to shift between lipid particles. SAA is mainly found on high density lipoprotein (HDL) particles; however, the investigators have found that in both mice and humans with obesity and/or diabetes SAA is found on low density lipoprotein (LDL) and very low density lipoprotein (VLDL) particles, and the investigators hypothesize that the presence of SAA on LDL or VLDL makes these particles more likely to cause cardiovascular disease. To determine what leads SAA to shift between lipid particles, SAA knockout mice will be injected with HDL containing SAA then blood collected at several time points over 24 hours, and the lipid particles will be isolated to measure SAA. In some experiments the investigators will compare different isoforms of SAA, different types of HDL particles, or induce expression of enzymes likely involved in shifting SAA between particles. To determine if the presence of SAA makes lipid particles bind vascular matrix more strongly, the investigators will collect carotid arteries and compare the extent of lipid particles bound to the vascular matrix in the vessel wall when the particles have or do not have SAA present. If this research confirms this hypothesis then the presence of SAA on LDL or VLDL may 1) be a new marker indicating humans at highest risk for cardiovascular disease and 2) be a new target of therapy to prevent cardiovascular disease.
Arterial calcification is very common in the incident hemodialysis population, ranging 71-83%.Given that cardiovascular disease is a major cause of mortality in the hemodialysis population, medial arterial calcification may contribute through increased risk of sudden death and congestive heart failure. Applanation tonometry is the method of choice to measure pulse wave velocity and pulse wave analysis. The primary objective will be to assess the effect of a 16 week exercise program on aortic pulse wave velocity as the vascular parameter and gait speed as the physical functioning parameter. The secondary objectives will assess the effect of the exercise program on ultrafiltration rates, weight, SBP, DBP, BNP, hsTroponin, serum calcium, phosphate, albumin, glucose, LDL, HDL, TG, glycated hemoglobin, hemoglobin, CRP, micro RNAs (21, 126, 133, 146a, 221/222 and 210) and hospitalizations.
