This study is a randomized, placebo-controlled, double-blind, two-arm trial of N=94 apparently healthy men and women to be recruited at a single investigational center in Northeast Ohio. Subjects will attend three study visits. During Visit 1, subjects will be screened for participation (i.e., medical history, physical exam, routine blood work, background baseline diet). Over the next 12 weeks, subjects will attend Visits 2 (baseline) and 3 (week 12), wherein assessments of body weight, waist circumference, urinary ketones, serum glucose, insulin, liver enzymes as well as other biomarkers of metabolic health, quality of life (SF-36 questionnaire), and various visual analog scales (VAS) for appetite, satiety, and cravings will be made.
This study is investigating the effects of 8 weeks of supplementation with Glucodia™, on glucose parameters, triglycerides and body weight as compared to a placebo. Half of the subjects will be administered Glucodia™, while the other half will receive placebo.
Background: - Rates of diabetes and heart disease in women are increasing. Early recognition of risk could help women live longer and healthier lives. Race and ethnicity may affect the best kinds of tests to use to screen for these conditions. Researchers want to compare risk factors for diabetes and heart disease in African, African-American, and white women. Doing so may help identify the most effective screening test for each group. This study will look at healthy African, African-American, and white women who are federal employees and contractors. Objectives: - To study risk factors for diabetes and heart disease in African, African-American, and white women. Eligibility: - Healthy African, African-American, and white women between 30 and 65 years of age who are federal employees or contractors. - For this study, African women must be born in Africa and have immigrated to the United States, and report that both parents are Africans. African-American women must self-identify as African-Americans, born in the United States, and have parents who both self-identify as African-American born in the United States. White women must self-identify as white and have parents who also self-identify as white. Design: - Participants will have four visits to study their risk factors for diabetes and heart disease. - The first visit is a screening visit. Participants will be screened with a physical exam and medical history. Blood and urine samples will be collected. They will also have an EKG test. Participants will also be shown how to fill out a 3-Day Food Record and wear an activity monitor called an accelerometer. The food record will keep track of how much participants eat for 3 consecutive days, including 1 non-working day. The accelerometer device will be worn for 3 days to monitor movement. - At the second visit, participants will have blood tests, an oral glucose tolerance test, and body fat measurements. They will also fill out questionnaires, review the food record, and have two imaging studies. - At the third visit, participants will have a longer glucose tolerance test. During the test, participants will receive both glucose and insulin and blood samples will be collected over several hours. Participants will receive lunch at the clinical center after the test. - At the fourth visit, participants will have a meal test. They will fast for 12 hours before the test. Participants will eat a specific meal and have blood samples taken during and after they eat. - Participants will discuss the results of these tests with the study doctors.
The investigators previously established that there was a high burden of disease among all categories of staff at the University of the West Indies, St. Augustine and in many ways, this group is typical of the working class of the Caribbean population. Many had poor lifestyle behaviors, 23.8% had Metabolic Syndrome (MS) with many having one or more MS components. Since most time is spent at work, the workplace is understandably the most logical location to address issues pertaining to health, disease prevention and wellness and on-site programs have yielded many health and other benefits to employees and employers alike. Onwards of the 1980s, numerous studies have been done on work-site intervention programs and these have shown that if a company is able to identify employees at risk for developing health problems and then intervene, health risks and the resulting medical problems are reduced. Such a program, if tailored to meet the needs of participants, may yield similar benefits among the staff of the University of the West Indies.
The purpose of this study is to assess the safety and efficacy of a natural health product among participants with elevated LDL cholesterol and triglyceride levels.
African Americans have a higher prevalence of vascular disease than Caucasians. Vascular disease can lead to heart attacks, strokes and even amputations. Insulin, a hormone which is secreted by the pancreas, affects not only glucose and fat metabolism but also vascular disease. Impairment of insulin s ability to remove glucose from the circulation is known as insulin resistance. To overcome insulin resistance the pancreas secretes extra insulin. These high levels of insulin affect circulating triglyceride levels by both promoting production of triglyceride by the liver and interfering with clearance of triglyceride from the circulation. Triglyceride in turn contributes to the development of vascular disease by causing both inflammation and hypercoagulability. Surprisingly African Americans are more insulin resistant and have a higher rate of vascular disease than Caucasians but have lower triglyceride levels. Because of the high rate of vascular diseases in African Americans, our aim is to determine if the adverse effects of triglyceride occur at a lower level in African Americans than Caucasians. To achieve this goal we will determine if there are differences in the effect of a meal on triglyceride levels and vascular function in a representative cohort of African American and Caucasian women. For this study we will enroll 96 women (48 African American and 48 Caucasian women). We are recruiting women because ethnic differences in triglyceride are even greater in women than men. We are enrolling women between the ages of 18 and 65 years. The study will involve several outpatient visits to the NIH Clinical Center. The first visit will be a screening to determine eligibility. At the second visit a test to measure insulin resistance will be performed. This test is called a frequently sampled intravenous glucose tolerance test. The third visit will be for the test meal. Before and at 2, 4 and 6 hours after the meal, blood will be drawn and vascular function measured. Vascular function is determined by taking blood pressure and then measuring blood flow in the arm with ultrasound. It is possible that individual differences in diet could affect the results of the vascular study on the day of the test meal. Therefore for 7 days prior to the test meal, the NIH Clinical Center will provide to each participant all their meals in the form of either trays or meals in a box. These meals will be consistent with the typical American diet and be 33% fat, 15% protein and 52% carbohydrate. In designing these meals, the dietician will take into account individual food preferences. This study is being performed in collaboration with the Harvard School of Public Health, the University of Texas Southwestern Medical Center and Indiana University. Therefore some blood drawn during Visits 2 and 3 will be sent coded, without personal identifiers, to each institution for analyses. ...
