600 Clinical Trials for Various Conditions
The investigators have hypothesized that dietary flavonoids reduce insulin resistance and subclinical inflammation secondary to reductions in intestinal inflammation and permeability and that these events are mediated through alterations in gut microbiota composition. To test this hypothesis, 30 overweight/obese men and women will be provided two well-controlled diets that are identical in macronutrient content (Protein, 17% en; Fat, 30% en; Carbohydrate, 53% en), but differ markedly in flavonoid content (Low Flavonoid Diet, 10 mg/1000 Kcals; High Flavonoid Diet, 340 mg/1000 Kcals). All meals for both diets will be prepared and fed for 6 weeks each in a randomized cross-over design with endpoints determined in duplicate during the last week of each diet period.
The purpose of this study is to evaluate the effects of both chronic and acute grape ingestion in a population of men and women at higher risk for both type 2 diabetes and cardiovascular disease (metabolic syndrome).
This study is being conducted to evaluate the efficacy of TA-65, a purified extract of Astragalus root, on insulin resistance, oxidative stress, and inflammation in individuals classified with metabolic syndrome.
Many metabolic complications can develop after liver transplant including: diabetes, high blood pressure, obesity, heart attacks and stroke. The goal of this study is to look at the safety and effect of 2 well known and established diet regimens on the people who had a prior liver transplant and investigate whether it helps with the control of these comorbidities.
The purpose of this study is to determine the dose-dependent impact of 6 month freeze-dried blueberry powder intake on insulin sensitivity and resistance, cardiovascular disease risk factors, and lung and cognitive function in overweight and obese participants with metabolic syndrome. We will also examine acute post-prandial effects of blueberry intake (at baseline and at 6-months).
Linkages between depression and cardiovascular disease have been well documented. These appear to be more than associations, and may reflect causal relationships through a number of proposed pathways, including decreased physical activity, poor dietary habits, medication non-adherence, and a direct impact on inflammatory mediators. Older adults are affected by both depression and heart disease, with increased risk in African American and Latino elderly. The BRIGHTEN-Heart trial tests the hypothesis that an enhanced primary care delivery system intervention which provides evidence-based, patient-centered mental health services targeting depression and cardiovascular risk factors can reduce the risk of development of cardiovascular disease in low-income elderly blacks and Hispanics. BRIGHTEN stands for Bridging Resources of a Geriatric Health Team via Electronic Networking, and in this intervention, specialty providers including geropsychologists, social workers, pharmacists, nutritionists, chaplains, occupational therapists, and others collaborate via the internet as a virtual team. The study will determine if such a virtual interdisciplinary clinical team collaboration can reduce depression in older (age ≥ 65) minority adults with comorbid depression and metabolic syndrome.
This study will compare how well a combination of borage and echium oils will reduce inflammation compared to fish oils and placebo oil in subjects that are diabetic or have metabolic syndrome.
People who are overweight are at increased risk of heart disease. Being overweight and having heart disease are linked in that both involve inflammation. Inflammation refers to the body's first line of defense against infection and injury. Metabolic changes in cholesterol, triglycerides (fat in the blood) and sugar in the blood caused by inflammation are similar to that in some people who are overweight. The investigators wish to examine the effects of inflammation on these metabolic changes that may lead to heart disease.
The goal of this study is to begin to test whether or not pioglitazone, an FDA approved medication used to treat high blood sugar, may be safe and effective in treating Major Depressive Disorder (MDD) in patients with comorbid Metabolic Syndrome (METSYN).
People with psoriasis have significantly higher rates of obesity, diabetes, heart failure and high blood pressure than the general public. The purpose of this study is to determine how substances produced in the fat (inflammatory markers) relate to the risk of heart disease in people with the metabolic syndrome and psoriasis. People with metabolic syndrome have insulin resistance, increased waist size, high blood pressure, or high cholesterol.
Metabolic syndrome consists of a group of co-occuring conditions that increase an individual's risk of developing heart disease, stroke, and diabetes. The purpose of this study is to evaluate the long-term effectiveness of chloroquine, a protein-activation medication, at reducing the progression of atherosclerosis in patients with the metabolic syndrome. Sub-study: Vascular endothelial growth factor(VEGF)and Cardiometabolic Risk, The purpose is to determine if the association of VEGF with atherosclerosis indicates that it should be a marker of the disorder.
Metabolic syndrome consists of a group of co-occuring conditions that increase an individual's risk of developing heart disease, stroke, and diabetes. The purpose of this study is to evaluate the short-term effectiveness of chloroquine, a protein-activation medication, at improving metabolic syndrome.
The metabolic syndrome consists of five concurrent conditions which increase risk of heart disease, stroke, and diabetes. Persons with the metabolic syndrome usually have high triglyceride and low HDL levels and are overweight. Low fat, high carbohydrate diets may not provide the same cholesterol-lowering benefits to obese individuals as they do to non-obese individuals. The purpose of this study is to compare the effects of a low fat, high carbohydrate diet versus a moderate fat, moderate carbohydrate diet on the heart, blood vessels, and cholesterol levels in individuals with metabolic syndrome.
The purpose of this study is to determine the effects of omega-3 fatty acids in the form of fish oil supplementation (approximately 2 grams per day) on the carotid intima-media (CIMT)progression (primary objective) and 2)(Secondary objective) lipid markers such as LDL, apo-B, and LDL buoyancy, on inflammatory burden as measured by CRP, on oxidative stress as measured by urinary isoprostanes, urine microalbumin/creatinine, and serum adiponectin a fat derived hormone in subjects with metabolic syndrome.
The purpose of this study is to examine the effects of clopidogrel compared to placebo on markers of inflammation in subjects with metabolic syndrome who are receiving background therapy including low dose aspirin.
Heart failure is a condition where the heart does not pump enough blood to the rest of the body. People with heart failure may have another condition called the "metabolic syndrome"( having excess fat in the belly, high blood pressure, high fat in the blood, low level of good cholesterol and high blood sugar). People who have both heart failure and the metabolic syndrome often see many doctors. A new clinic has been formed at Ben Taub General Hospital that includes a specialist in heart failure (cardiologist) and in the metabolic syndrome (endocrinologist) as well as patient teaching. The goal of this study is to randomize patients with the metabolic syndrome who are admitted to the hospital for heart failure to this clinic (collaborative care) versus the usual doctor appointments (usual care). The purpose of this study is to see if collaborative care is better medical care than usual care. Specifically, we will see if patients in collaborative care will have: 1. fewer admissions to hospitals for illness 2. better blood pressure, sugar, fat and heart failure control 3. better patient satisfaction and knowledge about their diseases 4. lower levels of inflammation.
The purpose of the study is to test higher versus lower doses of aspirin on markers of atherosclerosis in patients at risk of a first heart attack.
The purpose of this study is to evaluate the efficacy of topiramate compared to placebo in the treatment of obesity in metabolic syndrome. Secondary objectives include topiramate and weight loss effects on lipid levels, HbA1C, insulin resistance, and blood pressure.
The primary goal of this study is to assess the effect of aripiprazole on patients who developed metabolic syndrome while taking other second generation antipsychotic medications.
Oral contraceptives (OCs) are the most widely used method of reversible birth control. However, the long-term cardiovascular safety of the widely used low-dose OCs (ethinyl-estradiol \< 50 mcg) is still debated. Although cardiovascular events are rare in young women whether they use OCs or not, the risks of myocardial infarction and ischemic stroke are increased among users of OCs who have conventional cardiovascular risk factors such as use of tobacco, diabetes or hypercholesterolemia. However, the risk of cardiovascular events in OC users with emerging cardiovascular risk factors (such as obesity and the metabolic syndrome) have not been investigated. Recently, the metabolic syndrome has been linked with the risk of cardiovascular disease. The syndrome is a clustering of risk factors in a single individual, and its underlying cause may be insulin resistance. Whether the metabolic syndrome predicts a higher cardiovascular risk in OC users has not been studied. This is a critical problem because the metabolic syndrome is prevalent in 24% of adults. Until the cardiovascular risks in users of OC are clearly defined, the appropriate use of OC with the least harm would not be possible. The investigator's long-term goal is to understand the best way to prevent and treat cardiovascular disease in women. The objective of this particular project is to obtain pilot data on the extent to which the metabolic syndrome and obesity affects glucose metabolism and cardiovascular risks in women taking OCs. The researchers hypothesize that women with metabolic syndrome and obese women will have worsened glucose metabolism and elevated cardiovascular risks associated with OC use, when compared to normal weight women without the metabolic syndrome. Results of this study will clarify the risk factors for cardiovascular events in women taking OCs, and will serve as pilot data for a National Institutes of Health (NIH) proposal. Once the cardiovascular risk factors of OC users are understood, clinicians can make better informed decisions about contraceptive choices for their patients.
The purpose of this study is to define the mechanism(s) through which Obstructive Sleep Apnea/Hypopnea (OSAH) promotes abnormal metabolic processes which characterize the metabolic syndrome. The investigators hypothesize that the sleep fragmentation and intermittent sleep hypoxia which occur in OSAH patients promote oxidative stress and inflammation which in turn lead to insulin resistance, dyslipidemia, abnormal vascular reactivity and other processes which are consistent with the metabolic syndrome.
This study will determine the effects of a supplement in reducing symptoms of metabolic syndrome, a collection of symptoms that increase the risk for developing heart disease, stroke, and diabetes.
The purpose of this study is to determine whether chromium supplements can reduce symptoms of metabolic syndrome, a collection of symptoms that increase one's risk for developing heart disease, stroke, and diabetes.
Metabolic syndrome is associated with increased inflammatory cytokines and reduced adiponectin, that may be mediated in part by TNF production from abdominal fat. We reasoned that an anti-TNF agent would reduce C-reactive protein (CRP) and increase adiponectin, improving the inflammatory milieu associated with metabolic syndrome.
This study aims to to improve physical activity and metabolic outcomes for breast cancer prevention in South Asian Indian immigrant women.
This study aims to determine the daily rate of endogenous synthesis of oxalate using fasted urine collection and a low-oxalate controlled diet in patients with Metabolic Dysfunction-Associated Steatotic Liver Disease (MASLD).
The goal of this clinical trial is to test the effect of a supplement called MitoQ (mitoquinol mesylate) on bladder symptoms such as urgency and frequency in women 50 years and older who have the metabolic syndrome. The main questions it aims to answer are: * Is the study design feasible and acceptable to participants? * Do participants taking the study drug get any improvement to their bladder symptoms compared to participants taking a placebo (a look-alike substance that contains no drug)? Participants will take 2 capsules of the study drug every morning for 4 months, answer many questions about their health including questions about their bladder health, perform physical and cognitive testing, give blood and urine samples, collect urine over 24 hour periods 3 times over the 4 months of the study, complete 3 day bladder diaries about how much they drink and void, undergo electrocardiograms, have their vitals and measurements (weight, height, waist circumference) taken, participate in 4 visits to the clinical research area and participate in many phone calls of varying length. Researchers will compare participants who were taking capsules containing MitoQ and participants taking capsules not containing MitoQ to see if MitoQ improves their bladder symptoms (urgency, frequency, nocturia, incontinence, etc.)
The objective of this project is to provide evidence that L-Citrulline (CIT) supplementation can improve vascular function in the fasted and acute hyperglycemia conditions in middle-aged and older women with metabolic syndrome.
The purpose of this study is to assess the feasibility of our study procedures/protocols and to look at the potential effects of chiropractic care on people with metabolic syndrome.
Coronary vascular dysfunction is one of the "final common pathways" for the impact of multiple cardiovascular risk factors. The investigators will conduct a randomized, double-blind placebo-controlled study in individuals with the metabolic syndrome and baseline coronary vascular dysfunction to evaluate the impact of vericiguat, a stimulator of soluble guanylyl cyclase, on coronary vascular function using non-invasive cardiac magnetic resonance imaging.
