VITAL-IMPACT: Improving Cardiometabolic Health in Black Individuals Through Therapeutic Augmentation of Cyclic Guanosine Mono-Phosphate Signaling Pathway

VITAL-IMPACT
Start date: May 1, 2024
Phase: Phase 2
Study type: Interventional

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.

NCT ID: NCT06250270 Recruiting - Metabolism Clinical Trials

Effects of Casein Protein on Metabolism When Taken Prior to Sleep and in the Morning

Start date: October 1, 2022
Phase: Phase 1
Study type: Interventional

The purpose of this study is to investigate the effect of casein protein consumption both prior to sleep as well first thing in the morning on metabolism (increase satiety and appetite, lower resting metabolic rate, and lower blood sugar levels), when compared to nighttime protein or placebo consumption alone. Protein itself is a macronutrient that not only helps the body repair itself, and play a critical role in growth, it also aids in increasing satiety and decreasing appetite. Casein protein specifically is slow digesting dairy protein which may impact the body's metabolism for a longer period than other dairy proteins such as whey. The literature demonstrates nighttime protein ingestion prior to sleep increases metabolic rate and satiety the next morning. However, there appears to be no data on the metabolic effects of protein ingested both at night and in the morning.

NCT ID: NCT06174480 Not yet recruiting - Exercise Clinical Trials

Evaluation of the Response to Hypoxia at Rest and During Exercise in a Healthy Subject After a Cryostimulation Exposure

CRYOX
Start date: January 25, 2024
Phase: N/A
Study type: Interventional

Many information is available regarding human adaptations to cold or hypoxia. Adaptations to these environments and physical exercise constitute responses to physiological stress aimed at amplifying the organism's reactions and improving its performance. However, studies conducted so far to understand these adaptations and their underlying mechanisms have been organized in a dissociated manner, with each study focusing on only one of these specific situations (cold, hypoxia, or exercise). Understanding cross-adaptations is crucial, as human beings are often simultaneously exposed to several of these stimuli, and understanding this cross-exposure can be considered a prerequisite for pre-acclimatization strategies to these different environments. Cross-adaptations has been defined as follows: "It simply involves considering that long-term exposure (either continuous or intermittent) to a given unfavorable environment not only increases tolerance to that particular environment but also leads to gains or losses of tolerance to other unfavorable factors that the adapted organism had never encountered before." When specifically examining cross-adaptations to cold and hypoxia, only one study focusing on the human model is available. The lack of perspectives and positions regarding the results calls for further investigations. The main objective of this study is to assess the effect of repeated exposures to cryostimulation on the variation of the respiratory exchange ratio in hypoxia during exercise.

Metabolic Responses to Exercise and Recovery

Start date: April 1, 2023
Phase: N/A
Study type: Interventional

Exercise benefits health through diverse metabolic processes and is central to healthy ageing. However, intense exercise also challenges the body, causing cellular damage that must be repaired. This means that we need to identify the level of exercise that can optimise health, and this level might potentially differ by age and sex. Our research aims to tackle this question, by studying the metabolic responses of the body both to exercise and during the subsequent recovery in 48 healthy and active participants between the ages of 8-10, 23-27 and 53-57. Participants will complete an inclusion questionnaire and, if eligible, be invited to visit the exercise laboratory 4-5-hours. We will collect questionnaire data and body measurements before participants undertake exercise on a treadmill. Biological samples (blood from adults only and saliva from everyone) will be collected at three time points (before, right after and one hour after exercise).

NCT ID: NCT06082726 Recruiting - Metabolism Clinical Trials

The Systemic Concentration of Short-Chain Fatty Acids After Delivery in the Small and Large Intestine of Healthy Volunteers

Sistine
Start date: October 9, 2023
Phase: N/A
Study type: Interventional

The goal of this crossover study is to evaluate the systemic availability of short-chain fatty acids (SCFA) that are either administered in the small intestine or the colon in healthy volunteers. The main question it aims to answer is whether the site of administration affects the amount of SCFA that reaches the systemic circulation. On two test days participants will ingest capsules filled with SCFA that are specifically delivered in the small intestine or the colon. After ingestion, blood samples will be collected at regular time points.

NCT ID: NCT06054607 Recruiting - Metabolism Clinical Trials

Effect of Short-chain Fatty Acids on Aerobic Endurance

Start date: July 21, 2023
Phase: N/A
Study type: Interventional

Randomized, double-blind, placebo-controlled crossover study designed to determine the effects of increasing colonic short-chain fatty acid (SCFA) content on aerobic endurance in healthy adults, and to identify underpinning mechanisms. In random order, healthy physically active adults will consume provided diets low in fiber and supplemented with SCFA-enriched high amylose maize starch (a poorly digested resistant starch considered a fermentable fiber) or low amylose maize starch (a rapidly digestible starch) for 1-week separated by a ≥2-week washout. At the end of each intervention period, participants will complete an endurance exercise bout followed by a time trial. Biological samples will be collected to assess muscle and whole body metabolism, gut microbiota, inflammation, and gastrointestinal function.

NCT ID: NCT06033898 Recruiting - Metabolism Clinical Trials

Inactivity Duration on Lipid Metabolism

Start date: October 1, 2023
Phase: N/A
Study type: Interventional

The purpose of the study is to investigate the effect of different periods of physical inactivity on postprandial lipid metabolism in the morning after exercise by measuring plasma triglyceride levels and fat oxidation (burning). The study is a crossover intervention with all healthy participants performing three trials varying in length of physical inactive (12 hours, 24 hours, and 36 hours). All trials include a physical activity control phase (>10,000 steps/24hr), a physical inactive phase (<1,000 - 1,500 steps/12hr), a moderate intensity cycling session, and a high-fat tolerance test.

NCT ID: NCT06016530 Recruiting - Nutrition, Healthy Clinical Trials

Multi-level Molecular Profiling of Stress Exposure Under Standardized Food Intake: A Clinical Study

Start date: March 21, 2023
Phase: N/A
Study type: Interventional

Nutrition plays a crucial role in preventing various diseases, including cardiovascular and metabolic conditions. Moreover, it is gaining increasing attention in the context of preventing and treating psychiatric disorders. However, limited knowledge exists concerning the effects of food intake and stress on metabolism over time. To enhance the understanding of this subject, blood components in healthy volunteers will be examined during a standardized diet, focusing on the interaction between nutrition and stress. Physiological stress will be induced by subjecting participants to sleep deprivation for over 36 hours. Hormonal influences related to the female menstrual cycle are particularly taken into account in female participants. In conclusion, comprehending these processes can improve the understanding of nutritional physiology and contribute to advancements in clinical practice.
