Background: \- Cardiometabolic diseases are medical disorders that can occur together and affect the heart. They increase the risk of developing heart disease and diabetes. One disorder, psoriasis, is an inflammation that mostly affects the skin but can affect the entire body. Another disorder, atherosclerosis, is a process in which cholesterol is gradually deposited on the wall of arteries. This causes arteries to harden and become less flexible. Many cells that cause psoriasis also cause atherosclerosis. Researchers want to look at the relationship between cardiometabolic diseases and psoriasis. Objectives: \- To study the relationship between psoriasis and cardiometabolic diseases. Eligibility: \- Individuals at least 18 years of age who have psoriasis. Design: * Participants will be screened with a physical exam and medical history. * Participants will have up to seven outpatient visits over the 4 years. The first visit will be a screening visit. Visits 2 will be12 months after visit 1. Visits 3, 4, and 5, will be scheduled yearly for the next 3 years. If participants have a psoriasis flare with more severe symptoms, they may have an extra visit. Those who leave the study early will have a final visit with the full series of tests. * At visits 1, 2,and 5, and any flare visits, participants will have a physical exam and medical history. They will provide blood and urine samples, as well as optional tissue biopsies. They will also have heart function tests. Imaging studies, as well as optional photographs of affected areas, will be performed. These tests will also be performed at the final visit. * At visits 3 and 4, participants will have a physical exam and medical history. They will also provide blood and urine samples, and have heart function tests.
NCT07547098
This is a single-center observational registry study aiming to establish a structured clinical and multimodal imaging database for cardiovascular-kidney-metabolic (CKM) populations and to support lifecycle follow-up and outcome management. Adult patients aged 18-80 years with cardiovascular, kidney, and/or metabolic diseases or key data for CKM phenotyping will be enrolled at the First Affiliated Hospital of Fujian Medical University. The study integrates retrospective data entry and prospective follow-up, including clinical records, laboratory tests, medications, electrocardiography, echocardiography, vascular function assessment, carotid and abdominal ultrasound, bone density, coronary CTA and post-processing data. The primary outcome is the first occurrence of a cardiorenal composite endpoint. Participants will be followed for up to 5 years through active annual follow-up and passive monthly data updates to support risk stratification, real-world evidence generation, and CKM management pathway optimization.
NCT04888923
Background: Environmental exposures like pollution, diet, and stress can help cause human diseases, or make them worse. Researchers want to better understand how injury and inflammation are caused by these exposures. They want to collect biological and environmental samples and other data. They may use the samples to measure a range of factors, like hormones, toxins, and chemicals. This will help them improve their studies. Objective: To identify and understand how environmental exposures contribute to human disease. Eligibility: Healthy adults ages 18 and older Design: Participants will be screened with questions about their health history, demographics, and medicines they take. Participants may give blood, hair, stool, saliva, and/or urine samples. They may have a skin punch biopsy to collect skin cells. They may give fingernail or toenail clippings. They may give a sample of exhaled breath. Participants may give a sputum sample. They will inhale a saline mist and cough mucus into a cup. Participants may have their nasal passages brushed, scraped, or washed. Participants may give cheek cell samples. They will swish mouthwash and spit it into a cup. Participants who produce sperm may give samples. Participants may have bronchoscopy to collect fluid. A saline solution will be put into their lung and then suctioned out, washing areas of the lung. Participants may have a pelvic or transvaginal ultrasound. They may have lung function tests. Participants may collect household dust, urine, or stool at home. Participants will complete surveys about their health, diet, and exposures. Participation will last for one or more study visits. Participants may be contacted in the future to take part in other studies.

This study will be conducted to evaluate the efficacy and safety of a single dose of nexiguran ziclumeran (NTLA-2001) compared to placebo in participants with ATTRv-PN.
NCT06003153
The goal of this research study is to evaluate the pathophysiologic mechanisms by which genetic variation impacts response to an FDA-approved medication commonly used to treat type 2 diabetes called oral semaglutide (Rybelsus) and to characterize the physiological response to a mixed meal tolerance test (MMTT) before and after a 14-day treatment with oral semaglutide. The investigators will do this by measuring factors in the blood, such as sugars, fats, metabolites, and proteins, after eating a standardized breakfast meal at the first visit and after taking 14 doses of oral semaglutide over two weeks before the second study visit. The food (mixed meal breakfast) we will be studying is specially prepared to contain a set amount of protein, carbohydrates, and fat. The investigators hypothesize that understanding how the acute biochemical response to oral semaglutide differs by genetic variation will generate insight into drug mechanisms and type 2 diabetes pathophysiology.

Individuals of Chinese heritage are the largest and fastest growing segment of the US Asian population. US Chinese have sociodemographic characteristics and culture that differ substantially from other US Asians, and therefore, differ in social determinants of health, health status, and disease risk. US Chinese adults are at increased risk for cardiometabolic disease, related conditions (obesity, type 2 diabetes mellitus, hypertension), and systemic inflammation that promotes disease onset and progression. Immigration to a new country can substantially impact the gut microbiome which may promote systemic inflammation. Pilot interventions indicate a high-fiber diet rich in whole grains reduced inflammation and improved obesity. Additionally, the United States Department of Agriculture (USDA) supported, evidence-based HomeStyles intervention has demonstrated feasibility, acceptability, and efficacy in improving lifestyle behaviors and home environments associated with obesity risk in families. A lack of linguistically, culturally tailored interventions to their specific health needs makes it difficult for US Chinese to implement healthy lifestyle behaviors and reduce health risks. Interventions tailored for US Chinese that could attenuate modifiable cardiometabolic risk factors, understand physiological sequelae, and bridge health equity are not currently available. Thus, the overall goal of this project is to test the efficacy of HomeStyles in improving health outcomes in US Chinese. Project aims are to: A) Culturally adapt the HomeStyles intervention through community-engaged approaches. B) Conduct a 10-week, 2-armed Randomized Controlled Trial (RCT) to test HomeStyles intervention efficacy on health outcomes (dietary intake, physical activity, self-efficacy, HbA1C, waist circumference, and BMI), hypothesizing that participants randomized to the treatment condition will have greater improvements in health outcomes than control comparators. C) Examine associations between intervention participation and gut microbiota/systemic inflammation and test hypotheses that a whole-grain rich diet adopted by those in the intervention group will increase anti-inflammatory gut bacteria, reduce inflammatory gut bacteria, and lower systemic inflammation.
NCT01143454
Background: \- Researchers are interested in studying individuals who have known or suspected metabolic, inflammatory or genetic diseases that may put them at a high risk for heart diseases or diseases of their blood vessels. Depending on the condition being studied, both affected and nonaffected individuals may be asked to provide blood and other samples and may undergo tests to evaluate the heart, blood vessels and lung function. The testing is tailored to the individual and/or condition being studied. Nonaffected individuals may include relatives of affected individuals and healthy nonrelated volunteers. Objectives: \- To study individuals who have or are at risk for cardiovascular diseases, and in some cases their unaffected relatives and healthy volunteers. Eligibility: \- Individuals between 1 and 100 years of age. Participants may be healthy volunteers, individuals with cardiovascular diseases, or unaffected relatives of individuals with cardiovascular diseases. Design: * Participants will have some or all of the following tests, as directed by the study researchers: * Photography of the face and full body * Body measurements * Radiography, including chest or limb x-rays * Metabolic stress testing to study heart and muscle function * Echocardiography to study heart function * Magnetic resonance imaging (MRI) studies, including cardiovascular MRI, angiography, and contrast MRI, to study heart function and performance * Computed tomography (CT) angiogram to obtain images of the heart and lungs * Positron emission tomography (PET) imaging to study possible fat infiltration of the heart * Six-minute walk test to study heart, lung, and muscle function and performance * Vascular ultrasound to study blood vessel walls * Blood, tissue, and other specimens will be collected for research and testing, and will be taken either as part of the clinical study or during surgical procedures. * Follow-up studies may be performed under separate research protocols.

NCT06619834
The goal of this clinical trial pilot study is to test the feasibility, acceptability, and preliminary efficacy of a combined intervention strategy of 1) technology-supported financial navigation to address economic burden of disease and 2) peer support both to facilitate linkages to clinical care and community resources to address social risks and improve participants\' diabetes self-management. The main aims of this pilot study are: * To examine the feasibility and acceptability of technology-supported financial navigation and financial navigation with peer support * To examine trends in preliminary efficacy of technology-supported financial navigation and peer support versus financial navigation-alone on 1) A1c and blood pressure (primary outcomes), and 2) out-of-pocket costs, treatment-related financial stress, cost-related non-adherence behaviors, diabetes distress, diabetes self-care behaviors, and uptake of social care assistance (secondary outcomes). The investigators will assess whether a combined intervention of technology-supported financial navigation and peer support will produce trends in superior diabetes and social care outcomes to financial navigation alone via a 2-arm randomized controlled trial. Participants will * Complete 3 survey appointments at baseline, and 3 and 6 months. Each appointment will consist of a survey assessment, an HbA1C test, and two blood pressure readings over the phone. * Be randomized to either financial navigation only or financial navigation and peer support.

A pragmatic, randomized clinical trial to evaluate the effect of a heart failure (HF) risk assessment and prevention strategy incorporating HF clinical risk scores (WATCH-DM) with cardiac biomarker (NT-proBNP) paired with a clinical decision support tool to implement an intensive prevention strategy among patients with high risk focused on implementation of evidence-based HF preventive therapies.
NCT07420023
High-glycaemic foods contribute to elevated risk of obesity, type 2 diabetes, and cardiometabolic disease. Replacing digestible carbohydrates with dietary fibres is known to reduce postprandial glycaemic excursions, enhance satiety, and support beneficial microbial fermentation. However, limited evidence exists on how interactions between different isolated fibres within a processed food matrix may modulate these responses, particularly when such interactions could recreate structural features of intrinsic plant fibre networks that naturally restrict starch accessibility and alter fermentation dynamics. This randomized, single-blinded, placebo-controlled crossover trial will investigate how isolated dietary fibres, alone and in combination, influence metabolic and microbial responses when incorporated into a commonly consumed cereal-based food (scone). Overweight but otherwise healthy adults (BMI 25-\<30 kg/m²) will consume seven fibre-enriched scone formulations across two consecutive mornings per intervention phase. Outcomes include postprandial glycaemic response measured via continuous glucose monitoring (primary outcome), perceived satiety and energy intake, gastrointestinal symptoms, fermentation dynamics via breath hydrogen and methane, and gut microbiota composition assessed through 16S rRNA sequencing. This study will generate novel insights into potential synergistic interactions between isolated fibres within a food matrix and their consequences for glycaemic control, satiety, microbial fermentation, and community. Findings will inform next-generation food design strategies aimed at replicating complex intrinsic fibre structures to enhance the health impact of processed foods.

Fitness is one of the best predictors for heart and brain disease. To increase ones fitness, the American Heart Association (AHA) says to exercise at least 150 minutes per week or 75 minutes per week if really hard. These exercise guides are pretty effective, however not everyone will get the same results. What individuals do outside of the exercise bout can influence the effectiveness of exercise. One of these factors is our time sitting, which has caused the phrase "sitting is the new smoking". Other studies have said that the metabolic benefits of exercise are decreased when you exercise after a few days of low activity (less than 5,000 steps per day). This is important in that exercise may not be able to fully offset these times of inactivity. However, these studies were only looking at different fats in the blood. As exercise increases fat burn up to 10 times in the muscle, more research is needed to understand how inactivity affects the muscle during exercise and after exercise. This study will help answer two questions: 1) How does a day of sitting a lot affect the muscle's ability to respond to exercise? and 2) How does a day of sitting a lot affect carbohydrate and fat burn during and after a bout of exercise? The investigators will answer these questions by having people complete one day of inactivity (less than 5,000 steps) or normal activity (more than 8,500 steps). Subjects will then come in the next day to bike somewhat hard for 1 hour. The investigators will take blood samples before, during, and after exercise to measure energy sources. The investigators will also collect pieces of skeletal muscle before and after exercise to see how the muscle responded to exercise. This study is significant for the publication of exercise guidelines to minimize risk of heart and metabolic diseases.
NCT06580184
The goal of this waitlist control clinical trial is to learn if the tailored LEARN 2 platform can prevent HIV-related comorbidities with shared risk factors in men ages 18 and older living with HIV. The main question\[s\] are: 1. Can the virtual environment improve quality of life among these participants? 2. Does the LEARN 2 platform effectively serve as prevention education for HIV comorbidity shared risk factors? Researchers will compare participants receiving the LEARN2 virtual environment intervention to those in a waitlist control group to see if the intervention leads to improvements in quality of life and reductions in risk factors. Participants will be asked to: 1. Engage with the virtual environment weekly. 2. Participate in virtual live health educator sessions. 3. Complete daily assessments of personal health behaviors through Ecological Momentary Assessment.

NCT01174875
This study aims to examine the role of genetic and epigenetic factors, maternal nutrition, lifestyle, emotional health, and other environmental factors in pregnancy or postpartum period that can influence future maternal risk of metabolic and mental wellness, including body weight changes. The study will recruit women in early pregnancy and later follow their children after birth, tracking both the mother and child until the child reaches at least 20 years of age.
NCT05236374
The objective of the current study is to test the overarching hypothesis that the beef nutritive matrix is uniquely suited to direct dietary zinc to cellular compartments for improved metabolic function, leading to a greater effect on health outcomes. Specifically, whether beef, as a component of a healthy meal, will promote the absorption of zinc into cells, where the zinc will have greater effects on zinc-dependent metabolic processes supporting cardiovascular health. To maximize the observability of these beef-related effects, individuals who are 55- to 70-year-old who generally have a higher risk of zinc deficiency and cardiovascular disease will be enrolled.
NCT07386665
Type of Study: Clinical Trial Goal: The goal of this clinical trial is to investigate how performing exercise at different times of day (morning vs. evening) affects liver fat, cardiometabolic health, and gut microbiota in postmenopausal women. Participant Population/Health Conditions: The study will involve 63 sedentary postmenopausal women (aged 45-75) diagnosed with metabolic dysfunction-associated steatotic liver disease. Main Questions: The main questions this study aims to answer are: * Does morning exercise reduce hepatic fat more effectively than evening exercise? * How does time-of-day-specific exercise influence cardiometabolic markers? * Do changes in gut microbiota contribute to the metabolic effects of exercise timing? Participants Will: Be randomized into one of three groups: morning exercise, evening exercise, or a usual-care control group. Follow the assigned regimen for 12 weeks. The exercise groups will perform supervised aerobic and resistance training three times per week. Provide blood, stool, and imaging data before and after the intervention to determine the effects of the intervention. Comparison Group: Researchers will compare the effects of morning vs. evening exercise (and usual care) on hepatic fat reduction and cardiometabolic improvement, as well as changes in gut microbiota.
