Filter by:SYSDIET (Systems biology in controlled dietary interventions and cohort studies) is one of the three centres in the NCoE Food, Nutrition and Health, 2007-2011. It consists of 12 partners from five Nordic countries working on multidisciplinary fields of science related to nutritional biology. The main objective of SYSDIET is to reveal mechanisms by which Nordic foods and diets could be modified to promote health and prevent insulin resistance, type 2 diabetes and cardiovascular diseases, all of which being connected to metabolic syndrome. Furthermore, the aim is to build up a Nordic platform for cohort studies and carefully conducted multi-centre dietary intervention studies, where novel nutritional systems biology tools can be applied besides human studies also in animal and cell culture studies. In order to achieve the main objective a Nordic multi-centre randomized controlled human intervention study is being conducted in 2009-2010 in 6-8 centres of SYSDIET consortium. Health of the Nordic populations has substantially improved during the last 30 years. This is due e.g. to marked decline in cardiovascular morbidity and mortality. However, during the last 10-20 years increasing obesity and sedentary lifestyle have resulted in an increase of metabolic syndrome and type 2 diabetes. Having this background, the aim of the SYSDIET consortium is to carry out a controlled, randomized dietary intervention study in persons with features of metabolic syndrome to find out the effects of a healthy Nordic food on major abnormalities in metabolic syndrome. Altogether 167 persons aged 30 to 65 years were recruited from 6-8 centers (40-60 subjects/center) of the SYSDIET cohort. The main inclusion criterion is BMI 27-38 kg/m2. The subjects should also have at least two other IDF criteria for metabolic syndrome. Recruited persons will start the study by following their conventional diet for one month as a run-in period. After that subjects will be randomly assigned into Experimental- or Control-diet-group for 6 months. Experimental diet is rich in whole grain products, berries, fruits, vegetables and fish, and its fat intake is modified according to current Nordic recommendations. Control diet is based on the current information of the mean dietary intake and food consumption. The diets will be realized according to eating habits in each Nordic country.
The purpose of the FIT-O study was to estimate the prevalence of having a caregiver (paid and/or informal) among hospitalized cardiac patients by demographic factors such as patient age and race/ethnicity, and to link caregiver status to clinical outcomes following hospitalization. A secondary aim was to collect anonymous family tree data to provide an estimate of the number of first degree family members, their basic demographics, and the distance at which they live from the medical center.
While there is now undisputable evidence relating elevated plasma low-density lipoprotein (LDL) cholesterol levels to an increased risk of coronary heart disease (CHD), it is being increasingly recognized that a significant proportion of CHD events occur in individuals characterized by a cluster of additional metabolic and physiological perturbations now defined as the metabolic syndrome. Epidemiological and clinical evidence have shown us that nutritional factors, often in conjunction with obesity, play a pivotal role in the pathophysiology of the metabolic syndrome. In that regard, accumulating evidence suggest that a Mediterranean-style diet (MedDiet) may beneficially modify several components of the metabolic syndrome including plasma triglycerides (TG) and high-density lipoprotein (HDL) cholesterol levels, insulin resistance, waist circumference and markers of vascular inflammation. However, the physiological mechanisms underlying the cardioprotective effects of the MedDiet on features of the metabolic syndrome and the importance of body weight reduction in maximizing these effects represent key issues that have yet to be investigated. The general objective of the study is to investigate for the first time in a controlled feeding study the mechanisms and factors underlying the impact of the MedDiet, with and without weight loss on the dyslipidemic features of the metabolic syndrome.
1. Measurements of peak oxygen uptake (VO2peak) during passive leg cycling (PLC) combined with arm crank ergometry (ACE), leg vascular occlusion (100mmHg above systolic BP) combined with ACE, and FES isometric contractions combined with ACE in spinal cord injured (SCI). All the above mentioned parameters will be compared to Functional Electrical Stimulated (FES) lower extremity cycling combined with ACE (FEShybrid). The hypothesis is that VO2peak is significantly higher during FES hybrid cycling when compared to peak and submaximal PLC, leg vascular occlusion and ACE. But the values for VO2peak during FES isometric contractions combined with ACE is not significantly different from FES hybrid cycling. 2. Comparison of sub-maximal and peak VO2 values during arm crank (ACE) and wheelchair ergometry (WCE) in persons with spinal cord injury. The hypothesis is that wheelchair propulsion due to higher energy expenditure show higher work output and VO2peak than ACE. 3. Does 6 weeks of maximal strength training improve SCI subjects performance during WCE? WCE after 6 weeks maximal strength training is less strenuous owing to better work economy/ efficiency. 4. Effect from aerobic high intensity hybrid training on stroke volume (SV) and VO2peak in spinal cord injured men. 8 weeks of high intensity 4 times 4 interval training at 85-90% of peak heart rate during hybrid cycling. Hypothesis; VO2peak and SV will be significantly increased from training.
This research focuses on communication practices between patients and health care professionals, like nurses, doctors, or physician assistants. The goal is to help improve communication about heart health issues. This pilot (or Beta) study is designed to test our ability to recruit an appropriate sample of participants, and determine our ability to deliver and evaluate the effects of a web-based intervention. The investigators hypothesize that exposure to the intervention will result in measurable changes in self-reported knowledge, attitudes and behavior regarding communication between patients and health care professionals. Participants in this research study are being recruited from the people who currently receive care at the Richmond Family Health Center of the Oregon Health & Science University. People who participate in this study will be between 55 and 70 years old, speak English as their preferred language, and have one of several possible diagnoses related to heart health. These could include, for example, hypertension, diabetes, asthma, or obesity. Additionally, the investigators are recruiting a small number of health care professionals from the Richmond Family Health Center. Their participation will be similar to but separate from the participation of patients. All participants will take two web-based surveys. Some participants will use a web-based tool that hopes to help improve communication between health care professionals and patients. The surveys contain questions that explore the knowledge, attitudes, and behaviors of participants related to heart health and communication between health care professionals and patients. Data analysis will focus upon identifying any changes that occurred in knowledge, attitudes, or behaviors with respect to health communication after using the web-based tool, as well as learning about what influences the quality and nature of communication between health care professionals and the patients they serve.
This study is funded by the American Heart Association. The goal of this research is to prevent early cardiovascular damage before symptoms develop for persons with HIV infection. Evidence suggests that taking low doses of blood pressure and cholesterol medication reduces risk for heart disease in persons who are at increased risk (such as the case with HIV infection). Participants who are taking HIV treatment with an 'undetectable' viral load, and who do NOT need treatment for high blood pressure or cholesterol may be eligible to enroll. Participants will take a low dose cholesterol medication (or placebo) and a low dose of a blood pressure medication (or a placebo), and will be seen at 3 study visits over 4 months.
The final purpose of this study is to determine whether bronchodilation and cigarette smoking in Chronic Obstructive Pulmonary Disease (COPD) patients interact, resulting in an increase of cardiovascular disease. The aim of this part of the study is to demonstrate the basic mechanism: Does increased respiratory function after administration of a bronchodilator in patients with COPD lead to elevated pulmonary retention of the harmful compounds in inhaled cigarette smoke and to short-term biological effects associated with cardiovascular disease?
The investigators' aim is to implement an intervention to increase aspirin prophylaxis use among patients that is patient initiated, optimizes use of physician and staff time, appropriately compensates staff, provides clinicians with tools necessary for managing aspiring prophylaxis, and ensures continuous management.
The main objective is to elucidate the acute effects of an oral intake of either saturated, monounsaturated or polyunsaturated fatty acids on peripheral blood mononuclear cells (PBMC) whole genome expression of obese and type 2 diabetic obese subjects.
The investigators hypothesize that the degree to which older generally healthy but sedentary men and women improve a number of cardiovascular (CV) disease risk factors with 6 months of highly-standardized endurance exercise training will be a function of common genetic variations in candidate genes.
