Filter by:The aim of this study is to investigate the effect of barberry consumption on systolic and diastolic blood pressure, serum lipids, and inflammatory status. The study will involve cases having elevated BP (129/ < 85) and known hypertensive patients on medical treatment. Seventy people will be randomized into two groups, including intervention (barberry) or placebo groups. Before and after of 8 week intervention, 24-hour ambulatory blood pressure monitoring will be done and fasting venous blood sample will be taken to measure plasma lipids. In addition, 24-hour urine will be collected to measure its sodium content and estimate sodium intake.
Purpose: The primary purpose is to determine the combined effects of essential amino acids (EAA) supplementation and high intensity interval training (HIIT) on body composition, muscle characteristics, and muscle architecture in overweight men and women over the course of eight weeks. A secondary purpose is to determine the metabolic effects of EAA supplementation and HIIT on whole body protein turnover, metabolic rate, substrate metabolism, and metabolomics. A tertiary purpose is to evaluate the modulatory effects of sex on body composition, metabolism, metabolic profile, cardiorespiratory fitness, and hunger and satiety in response to EAA supplementation and HIIT. Participants: Healthy overweight and obese men and women (30-50 years) Procedures (methods): In a block randomized design, 78 healthy, overweight or obese men and women will be randomized, to one of four, eight-week intervention groups using a 2:2:2:1 group allocation design: 1) essential amino acids (EAA) supplementation (7.2 grams EAA daily); 2) HIIT, two days per week of cycle ergometry training; 3) EAA + HIIT; or 4) control (CON), receiving no intervention. Measurements of body composition, muscle characteristics, resting metabolic rate, substrate metabolism, and cardiorespiratory fitness will be measured at baseline, 4-weeks, and 8-weeks. Metabolomics and whole body protein turnover will also be measured at baseline and 8-weeks. Subjects will be asked to arrive to testing sessions following a 12 hour fast (except for water), consuming no food, caffeine, or alcohol. Participants will also be asked to abstain from physical activity for 24 hours prior to testing. Subjects will complete one electronic contact (phone/email screening) and up to 22 in-person sessions (enrollment; 5 testing sessions [2 at base, 1 at 4week, 2 at 8week]; 16 training sessions [for HIIT and EAA+HIIT]) over the course of 8 weeks.
Accumulating evidence from prospective observational studies and a large clinical trial suggests that nut intake lowers the risk of cardiovascular disease (CVD). Tree nuts are rich in unsaturated fats, soluble fiber, antioxidants, and phytosterols. The purpose of this study is to compare the effects of low calorie diets with a mixture of nuts in comparison with low calorie diets in improving inflammatory markers in patients with stable coronary artery disease.
This study will compare the systemic and white adipose tissue inflammatory profile of individuals who are classified as lean and obese. Blood and white adipose tissue samples will be collected in the fasted state to assess inflammatory status. There is evidence to suggest that markers of inflammation in the blood and white adipose tissue increase with increasing levels of obesity. However, the white adipose tissue total protein content and phosphorylation of proteins involved in inflammatory pathways has not previously been compared between lean and obese individuals. The investigators hypothesise that obese individuals will have increased levels of inflammation in the blood and white adipose tissue, compared to their lean counterparts.
This is an observational study to examine the cardiovascular mechanisms of increased cardiovascular mortality in those with high activity occupations.
Current approaches in primary prevention for cardiovascular disease are based on probabilistic approaches to estimate risk, using many of the widely available cardiovascular risks scores, with over 100 such scoring systems currently available throughout the world. The rationale for this practice is to select those individuals at greatest risk for more intense targets, reduce risk of treatment to those at minimal risk, and to maximize the cost-effectiveness of treatment. A recent Cochrane Systematic Review assessed the practice of using risk scores to select individuals for the primary prevention of cardiovascular disease. 3 The principal finding of the systematic review was that there was little or no effect of providing clinicians with cardiovascular risk scores when compared to standard of care (5.4% versus 5.3%; relative risk 1.01, 95% confidence intervals 0.95 to 1.08). The authors concluded that there is major uncertainty whether current strategies for providing risk scores and called for further research to address this concern. Extent of coronary artery calcium (CAC) is a strong risk marker for coronary events, with evidence mainly derived from observational studies and from prospective non-randomized studies. CAC, although endorsed for intermediate risk patients, is not widely adopted due to barriers in reimbursement. The cost of the test ranges between 100 and 300 USD in the United States, which may have limited the wide adoption of the test. Whether reducing the cost burden for CAC increases utilization for routine screening and its influence on physician practices and downstream testing is largely unknown. University Hospitals started offering low charge CAC (99$) since 2014. In 2017, University Hospitals started offering CAC for no charge for patients to improve access to this test, which has not traditionally been covered by insurance companies. The impact of no-charge CAC has never been studied.
Traditional randomized clinical trials (RCTs) have provided extremely valuable information on medical therapies and procedures that have changed the way heart diseases are treated. However, despite these contributions, traditional RCTs are costly, the findings may not be applicable to patients unlike those in the study, and the use of trial findings may be infrequent. These limitations may be addressed by incorporating 'big data' in RCTs, which is the emerging field using electronic information that is routinely collected in various large administrative health databases. The Community Heart Outcomes Improvement and Cholesterol Education Study (CHOICES) will test the potential of using 'big data' in a 'real-world' clinical trial to measure outcomes using routinely collected health information. CHOICES aims to increase the use of cholesterol-lowering statin drugs to prevent heart attack and stroke in high-risk health regions across Ontario using a 'toolbox' of interventions. The 'toolbox' of interventions are informational strategies targeted for both patients and family physicians to help improve cholesterol management and contribute to shared decision making for heart healthy goals.
The DASH diet (Dietary Approaches to Stop Hypertension) have been proven to lower risk of cardiovascular diseases. But the DASH diet is inconsistent with Chinese dietary pattern. In this study, based on the typical Cantonese diet, the healthy Cantonese diet is developed according to the DASH diet and the balanced dietary pattern of the Chinese Dietary Guidelines 2016. The randomized control trial is designed to investigate whether the healthy Cantonese diet has benefit to blood pressure, blood lipid, blood glucose and other cardiometabolic biomarkers among adults with cardiometabolic syndrome in Guangdong, China.
Under 50% of patients diagnosed with hypertension and treated in general practice, have reached a blood pressure within the recommended levels of the national guideline. Compliance is the main problem for these patients, but effective tools for increasing patient compliance are missing. The objective is to evaluate the risk-assessment and risk-communication tool: "Your Heart Forecast", to see if it can improve patient compliance, health literacy and empowerment. Patients will be followed in a cluster-randomised controlled trial in the setting of general practice, using surveys at inclusion and after 6 and 12 months. Besides surveys, the participants' blood pressure will be measured as a hard outcome and data will be drawn from various patient databases. After 6 months, qualitative interviews will be conducted, with a subgroup of patients from the intervention group. It is expected to find whether the use of Your Heart Forecast can lower patients' blood pressure and/or increase their compliance, health literacy and empowerment. The aim is to show if an increase in general health literacy and patient empowerment, as measured by Patient Activation Measure(PAM13) can be seen. The investigators hope to reveal whether this software can improve patient compliance and thereby be a reasonable tool to implement in the national blood pressure control program. In further studies, it should be shown if the cost of using this program is far less than expenses for hospitalisation due to complications and comorbidity to hypertension.
Associations between the built environment and health behaviours are robust, however (1) it remains unclear if the behaviours they elicit lead to meaningful improvements in health outcomes, at the population level and (2) little experimental evidence exists supporting these associations. The primary objective of this study is to capitalize on an urban natural experiment to determine if changing the built environment to support physical activity will (1) reduce the burden of CVD within a population and (2) if it's a cost-effective population intervention. An interrupted time series analysis will be performed over a period of 19 years to determine if the expansion of an urban trail network is associated with reductions in major advserse cardiovascular events (MACE) and CVD-related risk factors within a large urban centre in Canada.
