Filter by:The primary purpose of this study is to compare the change in blood carotene concentration between a food-based versus nutritional supplement-based intervention. This study will randomize up to 60 healthy volunteers to receive either carotenoid-enriched food; natural, mixed carotenoid supplementation; chlorophyll complex or placebo supplementation. Blood carotene levels will be measured before and after 28 days of supplementation. Preliminary data will also be collected on several biomarkers associated with vascular inflammation and endothelial dysfunction. These biomarkers will be measured before and during a fast food control meal at the beginning and end of the intervention period.
This pilot study will investigate the effects of acute peanut consumption on markers of inflammation, triglycerides and glucose. The hypothesis is that a high glucose/SFA meal will increase postprandial production of the inflammatory marker, C-reactive protein (CRP), and that the addition of peanuts to the control meal will reduce the production of CRP, as well as triglycerides and glucose.
The initial manifestation of symptomatic coronary disease can range from angina (or symptoms of angina), unheralded acute coronary syndrome (ACS), or unheralded coronary death. A better understanding of gender differences in initial presentation of coronary disease and the rate and predictors of progression to subsequent stages in coronary disease could help to identify which gender- specific factors might reduce or slow transition to more serious disease states and improve outcomes. The investigators' research focuses on the role primary care management of cardiovascular risk factors plays in gender differences in the progression to subsequent disease states and to mortality.
Cardiovascular disease (CVD) represents the first cause of mortality in industrialized countries such as Canada and the United States. In that regard, it is being increasingly recognized that a significant proportion of CVD events may be attributable to the presence of a cluster of metabolic and physiological perturbations defined as the metabolic syndrome (MetS). The National Cholesterol Education Program- Adult Treatment Panel III (NCEP-ATP III) has recently proposed a clinical definition to identify individuals with the MetS. This definition is based on the presence of at least three of the following five characteristics: 1- abdominal obesity, 2- hypertriglyceridemia, 3- reduced plasma HDL-C levels, 4- high blood pressure, 5- high fasting blood glucose levels. Recent data have suggested that the MetS based on this definition was associated with a 2 to 5 fold increase in the risk of CVD in men as well as in women. These are alarming figures since it has been suggested that as much as 35 to 45% of female aged > 65 years in the US may have the MetS. It is therefore imperative to develop new preventive strategies that will be efficacious in attenuating the impact of the MetS on the progressing rates of CVD in women. In that context, there is accumulating evidence to suggest that milk and dairy products may beneficially modify several components of the MetS. However, most of the available data to date are based on observational studies or interventional studies with minimal nutritional control. Thus, metabolically controlled studies that document the impact of milk consumption on cardiovascular risk factors associated with the MetS in women defined a priori as having the MetS are utterly lacking. The purpose of this study was to investigate the impact of milk consumption on features of the MetS in menopausal women presenting one or more features of the MetS.
The majority of trans fatty acids consumed by the general population is derived from products that have been formulated using significant amount of hydrogenated vegetable oil (the so-called industrial trans fat). Fat from ruminants also contains small amounts of trans fatty acid, which contribute, although to a smaller extent, to the total dietary intake of trans fatty acids in the general population. The negative impact of consuming industrial trans fat on health, particularly on cardiovascular disease, is being increasingly recognized. Based on data available to date, it is currently not possible to conclude if effects of ruminants and industrial trans fatty acid on cardiovascular risk are different. There is therefore an urgent need for a study that compares the impact of naturally occurring trans fatty acids such as those from dairy products and of trans fatty acids form industrial sources on cardiovascular risk factors as well as their mechanisms of action. The general objective of the study is to investigate the impact of naturally occurring trans fatty acids from dairy products (mainly vaccenic acid) on plasma cholesterol levels and other risk factors for cardiovascular disease.
The purpose of the investigators study is to investigate the impact of a commercial vegetable juice on dietary vegetable intake and select cardiovascular risk factors in a generally healthy population. The study was a 12 week study with 3 groups who received 0, 8 or 16 fluid ounces daily of vegetable juice, along with education on the DASH (Dietary Approaches to Stop Hypertension) diet. All participants came in for 3 study visits at 0, 6 and 12 weeks into the study.
This study proposes to describe how children s hypertrophic cardiomyopathy (HCM) risk status affects family functioning, behaviors, and relationships. HCM is the most common inherited cardiovascular single-gene disorder. Individuals with HCM may experience shortness of breath, chest pain, palpitations, dizziness, syncope, heart failure, and arrhythmias predisposing to sudden cardiac death at any age. Notably, HCM is the most common cause of sudden cardiac death in people under 30 years of age. Genetic testing can identify at-risk individuals; however, the impact of potentially life-altering genetic information on families remains largely unexplored. Increasingly, health care providers are providing the testing in children for conditions like HCM that are life-threatening and medically manageable without the benefit of understanding the psychological consequences. The few studies that have been conducted suggest that genetic testing in children may result in changes to family relationships, parental emotional wellbeing, parenting behaviors, and child functioning in a subset of children. One synthesis of these studies suggests that children as a group show little evidence for maladjustment to risk information, but that parents are affected by the carrier status of their children. The proposed study intends to further this body of knowledge by exploring the impact of children s risk status on families with HCM. Health care providers and researchers can inform their work with HCM families by better understanding the potential impact of genetic risk as an important component of families adaptation to the life-threatening information about their children. The families targeted for this exploratory study will be purposively sampled from those that have been aware of the children s risk status or not at-risk status for HCM for at least 3 months. The cross-sectional design is composed of semi-structured interviews with a parent and, separately, with his/her 13 to 23 year-old child who is either a carrier for HCM, a non-carrier, or at 50% risk for being a carrier. The interview will target issues related to the perceived impact of the child s risk status on family functioning, parenting behaviors and relationships. Data from the parent-child dyads will be analyzed for concordance/discordance along parallel themes. The results of this study may facilitate the understanding of the perceived impact of learning children s HCM risk status, which will inform both clinical care and future research. Importantly, since predictive testing in children for adult-onset diseases is generally discouraged, very little is actually known about its impact on families. Therefore, the study of this unique subgroup of an HCM population that uses clinically indicated predictive testing in childhood offers a preliminary opportunity to learn about predictive testing of minors....
The planned Study will be a retrospective study on the effect of ACE's vs. candesartan on cardiovascular events and on health economic effects in a "real life" setting in Sweden.
Cardiovascular disease (CVD) is the leading cause of death in the United States; more than 80% of veterans have > 2 risk factors for CVD. Our study is one of the first to examine the implementation of a tailored behavioral/educational self-management intervention in primary care clinics designed to improve CVD risk. The proposed study could result in a leap forward in CVD risk management among veterans for several reasons: 1) ) This is a novel extension of our previous interventions that have demonstrated improved BP, now designed to address multiple chronic conditions contributing to CVD risk, particularly hyperlipidemia and diabetes. The study focuses on both multiple CVD-related risk factor management and medication management 2) The intervention is multi-behavioral; it addresses patients' various health behavior (e.g., smoking, diet, and medication adherence). 3) Components of the intervention will include specific recommendations and transportability of intervention application software and tracking packages that will allow clinic managers to implement the intervention if it is effective.
The overall goal of the translational research is to evaluate the processes and outcomes of implementing, in a range of public health agencies, an intense, evidence-based behavioral weight loss intervention with demonstrated effectiveness among midlife low-income women. The intervention was originally studied in a single coordinated community health care center/church setting and delivered by research staff. The investigators will evaluate the intervention's translation and test its effectiveness as implemented by existing staff in six public health agencies supported by local community resources.
