Filter by:Our antibiotic studies indicated that cholesterol lowering was seen when fecal bifidobacterial counts were increased. Due to the dangers associated with prolonged antibiotic use we have been funded by the Heart and Stroke Foundation to see if gut bacteria can be modified by non-antibiotic means. Inulin a dietary fiber found in artichokes, chicory, leaks, onion, etc., (which also produces flatulence) has been shown to increase bifidobacteria and also appears to lower serum cholesterol. We will therefore test the fiber to determine its effectiveness in lowering serum cholesterol and whether it can be used to maximize the cholesterol-lowering effects of soy protein foods and viscous fiber foods (e.g. oats and psyllium).
This study is to determine the effects of Lovaza in platelet function studies
The overall objective of the Dietary Protein and Insulin Sensitivity Study is to test the hypothesis that increased protein in a diet with reduced carbohydrate (35% energy) can ameliorate insulin resistance in the absence of weight loss, and that this effect is independent of saturated fat content. Moreover, we will test whether such diets result in beneficial changes in total LDL cholesterol, small, dense LDL, and HDL cholesterol that are also independent of saturated fat intake.
To assess the effects of almonds on coronary heart disease (CHD) risk factors (serum lipids, measurements of oxidative stress and nitric oxide production) when added to the diets of subjects with high cholesterol. Also, to assess whether the amount of almonds consumed (i.e. almond dose) decreases CHD risk factors in a dose dependent manner. We hypothesize that since almonds have been shown to reduce serum lipids, we believe they will also increase nitric oxide levels related to their high levels of arginine and reduce markers of oxidative stress related to their content of bioactive phenolics. We anticipate that a dose-dependent relationship will be observed resulting in greater reductions in risk factors for coronary heart disease when greater doses of almonds are consumed.
The purpose of the study was to determine the effect on recovery after surgery of patients who received a standardized daily protocol of osteopathic manipulative treatment.Patients undergoing elective coronary artery bypass surgery were voluntarily enrolled in the study and assigned to one of three groups.One group received a standardized daily treatment protocol along with conventional care, another received daily similar placebo treatment with conventional care, and a final group received only conventional post surgical care.The research hypothesis was that daily treatment with osteopathic manipulative treatment would reduce hospital stay and hasten recovery from surgery.Persons in the treatment group had earlier discharge, and faster recovery of bowel function and basic mobility.
The hypothesis of this study is that soluble fibre may contribute to a reduction of the low density lipoprotein cholesterol (LDL-c), and the combined effect with a statin may achieve an optimisation of the cholesterol-lowering effects in adults with several cardiovascular risk factors.
Evaluation of the pharmacodynamic profile (antiaggregant profile, balance of prostanoids and nitric oxid) of a ASA-SR (slow-release)formulation in comparison with a ASA NR (normal release), 150 mg, during 12 months of treatment.
Participants will be asked to do the following: 1. A screening session in which you will take part in a diagnostic interview that will take about 2-3 hours to complete and will address your medical history. If you've recently participated in one of Dr. Haupt's or Dr. Newcomer's studies (HRPO #03-1281, 01-0134, or 04-0191) you may not have to complete this screening interview. 2. An ultrasound test of your heart and blood vessels where an ultrasound machine will use sound waves to create images that allow the main blood vessels in your neck to be examined. You will be lying down for the procedure, and a colorless gel will be applied to the side of your neck where the handheld probe (called a transducer) will be placed. The transducer will then be gently moved over each side of your neck. This procedure will take approximately 30 minutes. 3. A magnetic resonance image (MRI) study where the amount of fat in your liver will be measured. The MRI involves having your body painlessly scanned inside a tubular machine, while lying on a table for about 45 minutes. 4. Some routine blood tests to assess glucose (sugar) and lipid (fat) control and liver function, as well as an additional hepatitis screen if you have a history of hepatitis. You will go to the Intensive Research Unit (IRU) or Clinical Trials Unit (CTU) after an 8 to 10-hour overnight fast (except water). Approximately 42 ml (3 tablespoons) of blood will be obtained from you, and you will also have your height, weight, blood pressure, and waist and hip measurements taken. This will take approximately one hour. 5. A dual energy x-ray absorptiometry (DEXA) scan to measure your body fat and body muscle content. The DEXA scan involves lying on a table in a private room wearing a hospital gown for about 15 minutes while a machine silently measures the amount of fat in your body. The DEXA scan is part of the research study and gives the researcher a picture of how much fat is in your body.
The purpose of this research study is to learn whether or not people with bipolar disorder can reduce their risk of heart disease and related conditions by having a Care Manager provide self management and care management.
Physical activity is thought to be a key element in preventing the obesity epidemic and the associated cardiovascular and metabolic diseases. However population-based studies directed at promoting physical activity in youth have shown limited success in obesity prevention. The aim of this study is to assess whether an intervention integrating socioecological changes, which has the potential to induce sustained changes in physical activity, prevents overweight and cardiovascular risk in adolescents.
