127 Clinical Trials for Various Conditions
Participants will be 60-80 y men and women who vary their physical activity (steps/day) while their lipid metabolism is studied (n=24). Thereafter, another group (n=60) will perform 6 months of exercise training focused on developing maximal cycling power, during which their changes in muscle mass and practical function will be carefully measured.
The Western diet pattern or standard American diet is a modern dietary pattern that is characterized by high intakes of meat, pre-packaged foods, fried foods, high-fat dairy products, eggs, refined grains etc. When considering the role of saturated fat, it may be prudent to advise limiting all foods that contain saturated fats, including unprocessed/minimally processed meat, eggs, whole dairy in addition to processed, pre-packaged foods; however, this reductionist approach fails to take into account the food matrix and overall diet in which these nutrients are consumed. Epidemiological evidence suggests that increased modern, pre-packaged food consumption is a major risk factor for metabolic disease by promoting inflammation. Based on these data, the investigators hypothesize that the pro-atherogenic effect of the Western diet is caused by the pro-inflammatory effects of consuming large amounts of modern ultra-processed foods, and that consumption of a similar amount of fat from minimally processed beef, poultry, dairy, eggs, as part of an unprocessed diet will positively impact inflammatory markers and lipoprotein profiles of study participants when compared to a diet rich in modern ultra-processed foods.
Currently, controlled studies are lacking which test the benefits of: 1) ω3 PUFA; and 2) heat therapy on improving vascular-metabolic-microbiota health in Hispanic American populations. The investigator's objective is to determine if this modality (heat therapy i.e., warm water immersion, hot tubs) combined with dietary interventions (increased fish and/or fish oil intake) may be feasible treatments to improve cardiovascular risk factors and reduced comorbidities in Hispanic populations.
This study plans to learn more about puberty blockers and cross (testosterone and estradiol). There is not much known about how these medications affect hormone levels, heart health and overall general health in young transgender individuals.
The goal of this clinical trial is to determine the effectiveness of using a freeze-dried wild blueberry powder on cardiometabolic health, cognitive function, and gut microbiota composition in adult women with prediabetes.
This study investigates the potential of vericiguat, a soluble guanylate cyclase stimulator, to improve cardiometabolic health in obese Black individuals with insulin resistance by directly enhancing cyclic guanosine monophosphate (cGMP) activity. Given that this population has been shown to have lower cGMP activity and the association of lower cGMP activity with increased cardiometabolic disease risk, the proposed study hypothesizes that augmenting cGMP activity in obese individuals will improve insulin sensitivity and energy expenditure. This study is a placebo-controlled randomized trial involving 200 Black obese participants with insulin resistance, assessing the effects of vericiguat on insulin sensitivity, resting, and exercise-induced energy expenditure over 12 weeks. Additionally, it will explore changes in brown adipose tissue and gene expression related to energy metabolism in white adipose tissue, aiming to provide insights into how increasing cGMP activity may improve cardiometabolic health in Black obese individuals.
The primary aim of this randomized clinical trial is to compare the effects of three different HIIT protocols and a control group on cardiometabolic health in young adults with obesity. Participants will be randomly assigned to one of the following three groups, with each having varying work-to-rest ratios: 1) HIIT-A, 2) HIIT-B, 3) HIIT-C, and 4) control group. HIIT-A, HIIT-B, and HIIT-C groups will participate in six sessions of a running based HIIT program over a 2-week training period. Pre-clinical markers of cardiovascular disease, blood lipids and fasting glucose will be measured at the following three time points: baseline, post-intervention, and 2 weeks after the training cessation (i.e., measure for detraining effect). All measurements will be performed three days before the training program and three days after the intervention to avoid the effect of the last training session. Afterwards, the detraining test will be measured 2 weeks post intervention.
This pilot pre-post trial will address a gap in knowledge related to addressing modifiable risk factors for cardiometabolic disease through treating residual insomnia, sleep difficulties that remain after successful treatment of another condition, in the context of PTSD in understudied older adults. This study provides a non-medication treatment for PTSD called Cognitive Processing Therapy (CPT) followed by a non-medication sleep education and treatment program (Cognitive Behavioral Therapy for Insomnia, CBT-I) for sleep problems that remain after completing PTSD treatment in older adults with PTSD. The aims of this project are to evaluate 1) the added benefits of treating residual insomnia on sleep and PTSD symptoms; 2) the added benefits of treating residual insomnia following CPT on cardiometabolic risk biomarkers and quality of life; and 3) the durability of the sleep, PTSD, cardiometabolic and quality of life benefits of treating residual insomnia following CPT at 6-month follow-up in older adults with PTSD.
Natriuretic Peptides (NP) are hormones produced by the heart, and they have a wide range of favorable metabolic benefits. Lower levels of these hormones are associated with an increased likelihood of the development of diabetes and poor cardiometabolic health. Obese and Black individuals have \~30% lower levels of NP and are at a greater risk of developing cardiovascular (CV) events as compared to lean and White counterparts. Some people have common genetic variations that cause them to have \~20% lower NP levels. Similar to other low NP populations, these individuals with low NP genotype (i.e., carrying a common genetic variation called rs5068) are at a greater risk of developing cardiometabolic diseases. By understanding the NP response following the exercise challenge and the glucose challenge in individuals with genetically lower NP levels will help us understand how to improve cardiometabolic health in them.
Over half of American adults have overweight or obesity and are at high risk of developing type 2 diabetes and cardiovascular diseases. Although caloric restriction has many health benefits, it is difficult to sustain overtime for most people. Time restricted eating (TRE), a novel type of intermittent fasting, facilitates adherence to the intervention and results in weight loss and improvement of metabolism. The investigators propose to examine the efficacy of self-monitoring and TRE (10-h/d) vs. self-monitoring and habitual prolonged eating duration (HABIT) (13 hours/d) on weight loss and body composition, metabolic function and circadian biology, in metabolically unhealthy adults aged 50 to 75 y old, with overweight or obesity. The investigators hypothesize that TRE, compared to habitual long duration of eating, will decrease cardiovascular risk burden.
Black individuals are more likely to have decreased insulin sensitivity which results in a high risk for the development of cardiometabolic disease. The reasons for this are incompletely understood. Natriuretic peptides (NPs) are hormones produced by the heart that play a role in regulating the metabolic health of an individual. Low circulating level of NPs is an important contributor to increased risk for diabetes. The NP levels are relatively lower among Black individuals thus affecting their metabolic health and putting them at a higher risk for diabetes. This study aims to test the hypothesis that by augmenting NP levels using sacubitril/valsartan, among Black Individuals one can improve their metabolic health (as measured by insulin sensitivity \& energy expenditure) and help establish the role of NPs in the underlying mechanism behind increased risk for cardiometabolic disease in these population.
Traditional medical treatments are often based on research done exclusively in males, and recent research efforts in the physiology community have highlighted critical sex differences in disease presentation and progression. For example, the relative risk of fatal heart disease is 50% greater in obese, diabetic women as compared to their male counterparts, and women appear to respond differently to lifestyle interventions such as exercise compared with men. Chronic passive heat exposure (hot tub use) provides alternative or supplemental therapeutic potential for improving cardiovascular and metabolic health in obese women. In addition, passive heat exposure may offer specific cellular protection from stresses like a lack of blood flow (ischemia), which is the primary cause of fatal coronary heart disease. This study is investigating the possible cardiovascular and metabolic health benefits of chronic passive heat exposure, and whether regular hot tub use (3-4 days per week for 8-10 weeks) may reduce obese womens' cardiometabolic risk. The investigators are examining cardiovascular health through blood pressure, blood vessel stiffness, sympathetic ('fight or flight') activity, and responsiveness to stresses like increased or decreased blood flow. The investigators are also examining metabolic health through an oral glucose tolerance test and a subcutaneous fat biopsy. The goal of this research is to develop a therapy targeted toward the specific health needs and complications of obese women, in an effort to improve cardiovascular and metabolic health and provide therapeutic alternatives in this high-risk population.
Forty-eight prediabetic men and women (50-75 years of age) will participate in a 6-week feeding study in which they will randomized to receive either 10 g/day of inulin or placebo. All subjects will be fed an isocaloric diet (50% carbohydrate, 35% fat, 15% protein,) controlled for micronutrient content for 6 weeks to avoid the potential confound of individual differences in diet on gut microbiota. Measurements of intestinal permeability, insulin sensitivity, and skeletal muscle metabolic flexibility will be made prior to and following the controlled feeding period. Stool samples will be collected to assess gut microbial communities.
The purpose of this study is to determine whether consumption of 355 ml of watermelon juice will: 1. improve cardiovascular and overall metabolic health markers like blood pressure, heart rate, stiffness/flexibility of your arteries (blood vessels), blood sugar, cholesterol), and gut hormones 2. contribute to the body's ability to protect itself from the potential cell damage caused by harmful chemical compounds (produced when skin is exposed to ultraviolet (UV) B light, for example). This will be evaluated by measuring how resistant your skin is to the damage from UVB light exposure, as well as several markers of bodily stress blood and urine. This will be determined immediately after consuming the juice (to evaluate the effects the juice has on health right away), as well as after 4 weeks of daily juice consumption (to evaluate the effects the juice has on health when consumed consistently over time).
This study aims to see if a 12-week exercise program designed to reduce long periods of inactivity is feasible in newly diagnosed lymphoma participants receiving R-CHOP or POLA-R-CHP chemotherapy treatments, and whether it can improve heart health and reduce chemotherapy drug side effects.
The Trajectory study aims to determine whether childhood aerobic fitness, sleep quality, and diet quality predict cardiometabolic health during puberty and early adulthood, independently of adiposity.
A pilot randomized control trial (RCT) to examine the efficacy of a culturally tailored mindfulness intervention upon fasting cardiometabolic factors (including markers of glycemic control) and inflammatory gene expression in n=60 (n=30 intervention, n=30 wait-list control) low-income Spanish-speaking Latina pregnant women. The study will be conducted in partnership with MOMS, a nonprofit community organization that serves low-income pregnant and postpartum women.
Volunteers for the study are asked to participate in two laboratory sessions. In the first laboratory session, volunteers are asked to provide a blood sample which will be used to measure factors related to health. Participants also complete questionnaires related to demographic and health-related information and undergo evaluations of their body composition. In the second laboratory visit, participants are asked to have cardiovascular, neuroendocrine, and inflammatory activity measured during a brief period of rest and during a short challenging psychological task. Participants will also complete questionnaires. The study is designed to examine the associations between experiences such as trauma and resiliency with changes in bodily systems during a challenge and current health.
This randomized clinical trial aims to evaluate the effects of consuming two different doses of pulses (1.5 cups/week or 3 cups/week) in individuals with baseline intake below 1.5 cups/week, compared to a control group receiving standard nutrition education based on the United States Department of Agriculture's (USDA) My Plate guidelines. The main question the Pulses study aims to answer is: • What is the effect of increasing pulse consumption (in a dose-response manner) on specific cardiometabolic risk factors, including LDL-C, CRP, HBA1C, and blood pressure compared to standard nutrition education? For secondary outcomes, this study aims to answer the following: • Does increased pulse consumption improve the following: overall serum lipid profile (Total cholesterol (TC), HDL-C, Triglycerides (TG), diet quality (measured by the Healthy Eating Index), and participants self-reported satisfaction with life (SWLS) and Satisfaction with Food-related Life (SWFoL). All participants will attend biweekly classes and food demonstrations. The pulses groups will learn to prepare various pulse-based recipes, while the control group will receive guidance on preparing healthy meals following the USDA MyPlate recommendations.
The goal of this clinical trial is to learn how exercise and diet quality affect the health of adolescents with obesity. The main questions it aims to answer are: * Does exercise improve cardiometabolic health in adolescents with obesity? * Does enriching the diet with fruits and vegetables (FV) improve cardiometabolic health in adolescents with obesity? * Do exercise and FV diet together provide greater health benefits than either alone in adolescents with obesity? Researchers will compare four groups to see how exercise and diet impact health: * Standard Care Group: Receives the usual care for obesity. * Exercise Group: Receives weekly exercise coaching and participates in a 12-week exercise program. * Diet Group: Receives weekly dietary coaching and eats a diet enriched with fruits and vegetables for 12 weeks. * Combined Exercise and Diet Group: Receives both exercise and dietary programs, namely weekly exercise and dietary coaching, participation in a 12-week exercise program, and daily consumption of fruits and vegetables for 12 weeks. During the 12-week study, participants will attend three study visits to: * Provide blood, stool, and urine samples. * Answer questions about health, sleep, diet, and physical activity. * Undergo body scans to measure fat, lean, and bone mass. * Complete blood vessel function and liver fat content assessments. * Assess resting exergy expenditure. * Complete fitness tests. * Wear a fitness tracker to monitor physical activity and sleep patterns.
This project is part of the ACHIEVE GREATER (Addressing Cardiometabolic Health Inequities by Early PreVEntion in the GREAT LakEs Region) Center (IRB# 100221MP2A), the purpose of which is to reduce cardiometabolic health disparities and downstream Black-White lifespan inequality in two cities: Detroit, Michigan, and Cleveland, Ohio. The ACHIEVE GREATER Center involves separate but related projects that aim to mitigate and understand health disparities in risk factor control of chronic conditions, (hypertension, heart failure, and coronary heart disease) which drive downstream lifespan inequality. The present study is the prospective observational cohort component of ACHIEVE P1- EPI (Project 1) of the ACHIEVE GREATER Center and serves to characterize the population of patients with blood pressure (BP) levels above normal attending The Wayne Health Mobile Health Unit (MHU) events to better understand key factors (e.g., social determinants of health) that convey information about baseline BP levels and related clinical outcomes (e.g., follow-up clinic visits, BP control).
The goal of this clinical trial is to evaluate the effect of daily fresh watermelon consumption for 6-weeks on gut health, including microbiome diversity, gut barrier and immune function in young adults with overweight and obesity. The main questions it aims to answer are: 1. Will consuming fresh watermelon daily for 6-weeks will improve intestinal barrier health and increase microbiome diversity such as an increased population of beneficial 'probiotic' bacteria when compared to control participants consuming a low-fat snack? 2. Will consuming fresh watermelon daily for six-weeks will improve other health measures, including body-composition, blood pressure, blood vessel function, blood lipid profiles, and measures of inflammation, as compared to control participants consuming a low-fat snack for the same time period?
The objective of the UDECIDE study is to demonstrate adherence to decentralized clinical trials among underrepresented groups with cardiometabolic conditions .
The goal of this clinical trial is to assess the impact of table grape consumption on gut microbiome, intestinal permeability, systemic inflammation, and vascular function in healthy overweight men and women aged 45-70 years. The main questions it aims to answer are: * Does daily grape intake alter intestinal microbiome composition and intestinal permeability? * Are changes in gut microbiota and intestinal permeability correlated with changes in cardiometabolic risk factors (inflammation, vascular function, lipid profiles)? * Does response to grape intake on gut microbiota, intestinal permeability, cardiometabolic and inflammatory markers differ between men and women? * Are metabolic pathways modified by grape consumption able to explain the link between gut health and cardiometabolic factors? Researchers will compare freeze-dried grape powder to placebo powder to see if grape powder improves cardiometabolic risk factors. Participants will * Consume the powder dissolved in water twice daily for 3 weeks * Follow their usual diet, modified to limit polyphenol-rich foods * Visit the clinic at the beginning and end of the intervention for vascular measurements and blood sample collection * Complete a 3-day 24-hour dietary recall and collect stool sample before each visit
Accordingly, the purpose of this study is to evaluate the efficacy of 1) supplementation with Synbiotic (Plexus® Triplex), 2) commercially-available Probiotic, or 3) placebo control over 30 days on the gut microbiome, cardiometabolic health, body weight and body composition in healthy individuals.
Recently a dietary recommendation of 400 - 600 mg/ day has been proposed for the reduced risk of developing cardiovascular disease. Dietary flavanols can be obtained from the intake of foods such as tea, cocoa, wine, berries and apples. Incorporating Chardonnay Marc (the skins and seeds of Chardonnay grapes) into the diet can be an additional source of dietary flavanols. Like other flavanol-rich foods, Chardonnay Marc provides fiber and polysaccharides that may benefit gut health. This study seeks pilot data on the impact of the daily incorporation of Chardonnay Marc powder into the diet on markers of gut and cardiometabolic health.
This study is investigating the benefits of lean beef consumption on cardiometabolic health and gut microbiome.
The purpose of this study is to collect preliminary data on the feasibility, acceptability, and potential effects of a novel, remotely delivered resistance training program.
Rural communities in the southern U.S. suffer a disproportionate burden of morbidity and mortality from cardiometabolic disease, with traditional risk factors explaining only a modest proportion of the excess burden of disease. There is considerable evidence that multiple dimensions of sleep health, including sleep duration, efficiency, timing, and regularity, as well as the disorders sleep apnea and insomnia, affect cardiometabolic disease risk. However, there is currently a lack of systematically developed sleep data in rural populations. The RURAL Sleep Study is an ancillary study to a recently initiated longitudinal epidemiology study in rural Appalachia and Mississippi Delta (the RURAL Study). The RURAL Sleep Study will add measures of sleep health to the complex individual, social and environmental factors and health outcome measures being evaluated by the RURAL Study, by incorporating minimally burdensome measures of multiple dimensions of sleep health. The results are expected to inform health care providers, public health officials, and the general public of the prevalence, risk factors, and consequences of impaired sleep health in these rural communities, providing a critical basis for prevention, recognition, and management of sleep disorders and improvement of sleep and cardiometabolic health.
The purpose of this randomized controlled trial is to evaluate the impact of a multidimensional sleep health promotion intervention on blood pressure, glycemic control indicators, anthropometric markers of adiposity, and lifestyle factors in Hispanic/Latina/o/x adults. Participants will be randomized into an intervention or a control group. The control arm will receive standard Life's Essential 8 cardiovascular health educational materials. The intervention arm will additionally receive a multi-component intervention aimed at improving sleep health based on evidence-based sleep hygiene education and established behavior change techniques that include personalized sleep health feedback, goal setting and establishing a sleep health plan, coaching, self-monitoring, and addressing light and noise in the sleep environment. Mixed methods will be used to understand implementation determinants, processes, and outcomes, ensuring the successful completion and future expansion of this intervention.
