Lifestyle factors, such as diet, physical activity and sleep, are associated with the development of many chronic diseases. The objective of The Manitoba Personalized Lifestyle Research (TMPLR) study is to understand how these lifestyle factors interact with each other and additional factors, such as an individual's genetics and gut microbiome, to influence health. This is an exploratory cross-sectional observational cohort study of adults, with extensive phenotyping by objective health and lifestyle assessments, and retrospective assessment of early life experiences, with retrospective and prospective utilization of secondary data from administrative health records. A planned non-random convenience sample of 840 Manitobans aged 30-46 recruited from the general population, stratified by sex (equal males and females), body mass index (BMI; 60% of participants with a BMI >25 kg/m2), and geography (25% from rural areas,). These stratifications were selected based on Manitoba demographics. Body composition and bone density will be measured by dual energy x-ray absorptiometry. Blood pressure, pulse wave velocity, and augmentation index will be measured on two consecutive days. Chronic disease risk biomarkers will be measured in blood and urine samples. DNA will be extracted for genetic analysis. A fecal sample will be collected for microbiome analysis.
The Canadian Australasian Randomized Trial of Screening Kidney Transplant Candidates for Coronary Artery Disease (CARSK) will test the hypothesis that eliminating the regular use of non-invasive screening tests for CAD AFTER waitlist activation is not inferior to regular (i.e., annual) screening for CAD during wait-listing for the prevention of Major Adverse Cardiac Events. Secondary analyses will assess the impact of screening on the rate of transplantation, and the relative cost-effectiveness of screening.
The validity and applicability of different clinical risk scoring models in a variety of settings of interventional cardiology is evaluated in a retrospective and continuing prospective single-center registry at University Hospital Düsseldorf. Risk-adapted safety interventions are additionally tested.
The purpose of this study is to examine how the environment and neighborhood characteristics affects the health of the area residents. The study will help determine how changing neighborhood characteristics, such as green space, affect heart health, risk factors for other diseases, sense of well- being or neighborhood cohesion.
Patients who are on chronic dialysis and 70 and older are frequently on multiple medications including statins. However, the benefit of statins in dialysis patient population is uncertain. Several randomized trials showed no benefit of statins on mortality in dialysis patient population. Guidelines recommend not starting statins in patients on dialysis who are not already taking them. However, there are no guidelines on what to do in patients who are already taking statins. The investigators are doing a short pilot study to discontinue statin in our dialysis patient population and evaluating the effects on discontinuation of statins on quality of life, cognition, as physical strength.
The Investigator hypothesize that Dapagliflozin will improve EPC number and function AND Saxagliptin in addition to Dapagliflozin (additive effect) may improve EPC number and function even more than Dapa alone, compared to placebo. The Investigator propose a 3-arm randomized, parallel group, longitudinal study of 16-week intervention duration. Participants will be randomized to 3 groups: Group A: Dapa (10 mg) + Saxa Placebo, Enroll n=15, retain n=12 Group B: Dapa (10 mg) + Saxa (5 mg), Enroll n=15, retain n=12 Group C: Dapa Placebo + Saxa Placebo, Enroll n=15, retain n=12
Informal caregivers play an integral role in managing complex, chronic disease patients providing services equivalent to an estimated economic value of $470 billion. The inclusion of informal caregivers in the healthcare team can improve care coordination and make health care safer by reducing potential medical errors caused by miscommunication. the investigators reason that a properly designed PHR with a simplified user interface and easy access to relevant content can improve the management of chronic diseases and better integrate caregivers and patients into the healthcare team.
This is a cross-sectional retrospective study of laboratory records of patients who take electrolytes blood tests containing the data of the serum potassium level. This study is an observational one, and there is no intervention into routine clinical practice either in terms of therapy, or special examinations.
This study will assess the amount of energy that the heart will deliver to the central circulation and the efficiency of that energy transfer, in patients undergoing a coronary artery bypass graft operation. Measurements will be taken just after induction of anaesthesia and repeated just after the end of the operation. The total energy delivered by the heart will be calculated by multiplying a pressure curve from the artery in the hand with the instantaneous ultrasound recorded cardiac output flow curve. The energy responsible for the acceleration of the blood volume, known as oscillatory power will also be calculated. The energy transfer will be calculated using a mathematical model based upon other ultrasound and blood pressure recorded variables. We would like to see if any alteration in energy delivered is in part due to impairment in energy transfer or alteration of fraction of oscillatory power rather than a change in total energy production. We would also like to study if there are changes in the oscillatory power after cardiac bypass surgery. The patients will be sampled sequentially into the study. We are not aware of any such studies undertaken in humans previously.
