Cardiovascular Risk Factor clinical trials at UC Cancer

8 research studies open to eligible people

Showing trials for
  • A Study of the Effect of Orange Juice or Sugar-Sweetened Beverages on Risk Factors for Type 2 Diabetes and Cardiovascular Disease

    “In this study, the study team will provide meals and either sugar-sweetened beverages or orange juice.”

    open to eligible people ages 18-50

    The objectives of this proposal are to address the gaps in knowledge regarding the metabolic effects of consuming orange juice, the most frequently consumed fruit juice in this country, compared to sugar-sweetened beverage.

  • Activity Trackers for Improving BP

    open to eligible people ages 8-30

    The study aims to determine if use of physical activity trackers coupled with provider feedback will increase awareness of young adults of their physical fitness and improve blood pressure levels. The goal of this pilot study is feasibility, with a secondary goal of examining potential effect sizes for planning purposes for a larger randomized controlled trial.

  • Habitual Diet and Avocado Trial

    open to eligible people ages 25 years and up

    The Habitual Diet and Avocado Trial will evaluate the effects of providing one avocado per day for recommended consumption over a 6 month period in a cohort of approximately 1000 free-living participants with increased waist circumference in comparison with a control group that will maintain their habitual diets. Participants will be recruited and screened at 4 clinics in 4 locations: Pennsylvania State University; Loma Linda University; UCLA, and Tufts University (250 per site).

  • Healing Our Hearts Minds and Bodies: CVD Reduction in Persons With HIV

    open to eligible people ages 18 years and up

    "Healing our Minds and Bodies" (HHMB) uses a a hybrid type II effectiveness/implementation study design to increase both patient and organizational readiness to address trauma and CVD risk among African American and Latino persons living with HIV or AIDS (PLWHIV).

  • Short-Term Cardiovascular Effects of E-Cigarettes: Influence of Device Power

    open to eligible people ages 21 years and up

    This study will examine the short-term cardiovascular (CV) effects of e-cigarette device power in a randomized, crossover clinical and behavioral pharmacology study of experienced adult e-cigarette users (N=21). The specific aim is to determine the impact of e-cigarette power on nicotine pharmacology, systemic exposure to toxic volatile organic compounds (VOCs), and short-term cardiovascular effects.

  • The Effect of Daily Mango Intake on Cardiovascular Health

    open to eligible females ages 50-70

    In the current proposal the investigators seek to evaluate the acute and short-term effects of mango intake on vascular and platelet function in postmenopausal women between 50 and 70 years old. Our aims are 1) to determine if two weeks of daily mango intake will result in favorable changes in measures of vascular function, as measured using peripheral arterial tonometry (PAT) and platelet reactivity, in overweight and obese postmenopausal women. 2) to determine if two weeks of daily mango intake will change the fermentation capacity of gut microbiota. Investigators hypothesize that the daily intake of 330 grams of mango (2 cups) will significantly increase PAT while reducing platelet aggregation after 2 hours and two weeks of daily intake.

  • The Effects of a Mobile Health Intervention and Health Coach Text Messaging on Cardiovascular Risk of Older Adults

    open to eligible people ages 60 years and up

    This study, "Fitness Intensive Therapy (Get FIT) to Promote Healthy Living in Older Adults", will test a mobile-health based intervention which includes use of a Fitbit activity tracker for 3 months, a smartphone application that tracks daily food intake, and one 45 minute counseling session to create personal goals and provide patient education by a health coach; versus Get FIT+ (the same items) plus personalized text messages focusing on participant's activity and nutrition progress as monitored in the app, from the health coach for 3 months. The investigators will measure the impact on participant's diet, physical activity, clinical outcomes, psychosocial well-being, and engagement.

  • Walnut Study

    “Postmenopausal Women Needed for a Research Study”

    open to eligible females ages 45-65

    This study seeks to confirm and extend previous finding that four weeks of daily intake of 40 g of walnuts improve microvascular function, increasing the reactive hyperemia index (RHI), effects which were greatest in individuals with the worst initial RHI and correlating to circulating levels of vasoactive plasma epoxides. The current trial will enroll postmenopausal women who are at risk for cardiovascular disease due to their menopausal status and increased central adiposity. The initial trial focused on non-esterified (i.e. plasma) derived oxylipins, but substantial and unique changes were also observed in the esterified lipoprotein pool. The current study will add the esterified lipoprotein pool, important, as the mechanisms by which walnut intake influences endothelial function are currently undefined, but may include lipoprotein induced modulation of vascular hemostasis. As a secondary objective, primary metabolism and urolithin metabotype will be analyzed as a way to capture the influence of potential differences in habitual diet and metabolism on physiologic response. Therefore, this study will combine measures of cardiovascular physiology, metabolomics, and walnut-derived metabolite analyses to assess the 12 week influence of 40 g of daily walnut intake on the health of overweight and obese postmenopausal women.
