Filter by:Obesity is epidemic in Australia, and current preventative strategies have had limited success in alleviating this health crisis. While numerous options are available for treatment of obesity, most do not result in sustained weight reduction. Obesity results from an imbalance between energy intake and expenditure, therefore new methods that correct this imbalance are essential for effective long-term treatment. Rodent studies show that brown adipose tissue (BAT) can burn more energy than any other tissue in the body, therefore targeting BAT to increase its activity (energy burning rate) and quantity in humans is potentially a powerful tool for the treatment of obesity and related diseases. BAT has only recently been irrefutably identified in adult humans therefore little is known about how it functions in humans.
The aim of Prevent CardioKids is to evaluate to what extend disturbed vascular function markers are already present in children of different weight categories and whether these are age dependent. Also differences - and relationships - between vascular function measurements and plasma biomarkers between lean and overweight/obese children will be compared.
Heart disease and stroke are the number one killers world-wide. When someone has hypertension, the constantly elevated blood pressure damages their blood vessels and the organs that they supply blood to. This causes stroke, heart attack, heart failure, kidney failure and dementia. Finding and lowering high blood pressure to normal with lifestyle changes and if necessary medications, lowers the risk of these outcomes. Canada has high rates of blood pressure control compared to other countries in the world, due in large part to the successful dissemination of hypertension guidelines. However remote and disadvantaged communities have not been as successful and need additional measures to help achieve the same level of blood pressure control as the rest of the country. The DREAM-GLOBAL team has extensive experience working with Canada's Aboriginal Communities and a large community in Tanzania. The DREAM-GLOBAL project will integrate innovations in technology with the implementation of guidelines-based blood pressure control and through partnerships with experts in government and industry, overcome barriers to lowering blood pressure in Canada's Aboriginal Communities, and in a community in Tanzania. Tools will be developed and tested that will close the circle of care around people with hypertension by bringing measurement data to the medical record and health care provider and also sending useful medical feedback to the person with hypertension via secure data servers and routine SMS messaging on cell phones. The system will be tested for effectiveness of diagnosing and also for managing hypertension. To begin the process of preventing hypertension, the team will also explore with an Aboriginal community how to create policies to reduce the sodium content in their food. If proven effective, DREAM-GLOBAL can also become a platform for managing other chronic diseases.
The epidemic data shows that prehypertension is associated with cardiovascular disease, and heavy dietary salt intake could improve the developing of hypertension. We detected the risk factors of coronary atherosclerosis of prehypertensive patients with different levels of salt intake. The aim of this multicenter prospective, randomized controlled study is to evaluate regular physical exercise and salt diet effects on progression of coronary artery disease in patients with prehypertension.
Cardiovascular disease (CVD) is the leading cause of mortality in patients with end-stage renal disease (ESRD), which means that it is important to find out risk factors of CVD in order to prevent or treat it. In recent years, there has been more and more recognition of a very high prevalence of CV calcification in the ESRD population. Many observational cohort studies have shown that CV calcification in these patients can predict mortality, CV mortality and morbidity. Electrolyte imbalance is easily found in the ESRD patients which may result in vessel calcification. Calcification leads to arterial stenosis and increasing arterial stiffness and then heart afterload, both contribute to the development of CVD. Besides, metabolic syndrome, insulin resistance, and dyslipidemia pave the way for a chronic, immune-mediated vascular inflammation and cardiovascular disease. These factors are prevalent in ESRD patients, which would also cause arterial stiffness. Arterial stiffness and stenosis would increase the risk of CV events and mortality. Aortic pulse wave velocity is strongly associated with the presence and extent of atherosclerosis and constitutes a forceful marker and predictor of cardiovascular risk. At the same time, high prevalence of peripheral artery occlusion disease (PAOD) should also be found while arterial stiffness and stenosis, which would increase the condition of infection and gangrene. Thus, life safety and quality would be influenced severely and early detection might prevent future amputation. Uremic patients also have a higher risk for metabolic syndrome. Therefore, more studies to evaluate the condition of arterial stiffness and PAOD, especially in HD patients, are needed for future management and preventions of CV related morbidity and mortality.
Many conditions and cardiovascular diseases (including stroke) are better managed with regular exercise training. The expected effects are partial reversal of adverse effects on heart and blood vessel structure and function, improved glycemic, tension and weight control. Physiologically, the aorta maintains low left ventricular after-load, promotes optimal sub-endocardial coronary blood flow, and transforms pulsatile into laminar blood flow. Increased aortic stiffness may ultimately contribute to left ventricular dysfunction. Regular exercise training is likely to decrease the pulse wave velocity (a measure of the aortic compliance). Some subjects seem more responsive than others, and they may not expect the same benefit of exercise training. To the best of our knowledge, this has not been explained yet.
Background: - Past studies suggest that the best way to improve heart health in the Black community is through community-based programs. Researchers will partner with DC community leaders. They will collect information about the health and health needs of people in mostly Black churches in DC. They will study things that affect heart health, like diabetes, blood pressure, cholesterol, and weight. They will also study how technology can keep track of activities and health. The information will show the health needs of this church-based community. Objectives: - To create an intervention for future programs to improve heart health in African-American churches in Washington, DC. Eligibility: - Adults ages 19 to 85 who attend one of the study churches. Design: - Participants will visit their church for a 4-hour health exam. They will have their blood pressure and body measurements taken. They will have a drop of blood taken from their finger with a small needle. This blood will be tested for blood sugar and cholesterol. Participants will be given the results of these tests. - Participants will answer questions about their health. - All participants will be given an activity monitor to wear for 1 month. The activity monitor is worn around the wrist. Some participants will also receive an activity monitor that is worn around the waist. Participants will be given instructions on how to wear the activity monitors and follow the results on a website. - At the end of 1 month, participants will return one device (they can keep the other). They may receive a gift card for completing the study.
We analyze retrospectively the relationship between traditional cardiovascular risk factors as hypertension, obesity, dislipidemia and diabetes and hand or knee osteoarthritis and we compare the results with a control groups of patients with soft tissue disease with no other rheumatologic condition.
Clopidogrel is crucial as antiplatelet treatment in patients undergoing percutaneous coronary intervention (PCI) with stent implantation and during one year after PCI, to prevent atherothrombotic complications. However, clopidogrel is ineffective in certain patients due to genetic mutation in CYP2C19 gene a specific enzyme in the liver required for metabolism of clopidogrel. Therefore, the purpose of this study is to test these patients genetically at bedside and prescribe an alternative drug such as Ticagrelor (90 mg twice daily) or prasugrel ( 10mg once daily or 5mg once daily if the patient older than 75 years or a body weight < 60kg) if they are carriers of the allele 2 or 3 of the mutated gene.
The purpose of the CAMONA study is to demonstrate the feasibility of cardiovascular molecular calcification (CMC) assessment by means of 18F-sodium-fluoride (18F-NaF) positron emission tomography (PET) computed tomography (CT) in a prospective cohort of healthy control subjects and subjects with cardiovascular disease.
