Filter by:This project comprises an initial crossover placebo-controlled neurophysiological study to ascertain the effect of acute ketone ester ingestion on motor cortex plasticity, followed by a second 2-week intervention study aimed to compare the effect of a ketogenic diet versus ketone ester supplementation on motor cortex plasticity, resting brain function and structure, and metabolic and neuroendocrine responses.
To examine the acute changes in cardiometabolic and neurocognitive outcomes in response to exercise combined with ketone ester supplement in overweight/obese adults.
The prevalence of obesity and obesity-related diseases are on the rise worldwide. The widely accepted approach in dietary treatment of obesity is the calorie-restricted three meals-three snacks a day diet; however, alternative approaches are needed. This study was conceived with a view to comparing time-restricted eating, a method which can be easily conveyed and applied in overcoming obesity, to a six meals a day diet. 174 participants aged between 18-65 with a BMI>25 kg/m2 were included. Diet lists with similar calorie, macro counts suitable for their respective group were prepared. Anthropometric measurements, blood pressure, blood tests were analyzed before the study and at the end of the 8-week.
This trial aims to evaluate the impact on cardiovascular risk control in individuals in risk of being affected by hepatic steatosis through the implementation of a screening test (Fatty Liver Index) in Primary Care. Medical teams in a primary care center will be divided into 2 groups, with one group using the screening test in their clinical practice. The number of interventions on cardiovascular risk occurring in patients attended by each group of medical teams will be evaluated and compared.
The primary purpose of this project is to observe the effects of Cognitive Behavioral Psychotherapy-based weight-loss mobile application (Bi' Kilo) in 4 essential areas (Anthropometric, Biochemical, Psychometric, Cognitive) in overweight and obese individuals and to test whether these effects will persist after ten weeks. In this context, the original value of the proposed study is that a mobile application will be produced that is suitable for the culture and whose effectiveness has been scientifically proven. In our current project proposal, the measurements of the participants will be evaluated holistically together with both tests and inventories, as well as physical measurements and biochemical data. In this study, the usability of the mobile application to be developed will also be evaluated and reported. The study group of the research will consist of overweight and obese individuals. The first stage will be a pilot study to identify the shortcomings of the Bi'Kilo mobile application. After eliminating the deficiencies of the Bi' Kilo mobile application, a working group will be formed in the second phase of the research. At this stage, the sample will be divided into two different groups within the scope of the study and a study group and a control group will be formed. The study consists of three phases as preparation, implementation, and follow-up. Measurements of the participants will be made at the beginning (Anthropometric, Biochemical, Psychometric, Cognitive), at the end of the six-week implementation phase (Anthropometric), and at the end of the four-week follow-up phase (Anthropometric, Biochemical, Psychometric, Cognitive).
The goal of this clinical trial is to understand how the blood sugar-lowering hormone insulin works in healthy adults versus those who are at risk for type 2 diabetes. The study will use a drug called alpelisib, which interferes with insulin's actions in the body, to answer the study's main question: does the liver continue to respond to insulin's stimulation of fat production even when it loses the ability to stop making glucose (sugar) in response to insulin. Researchers will compare the impact of single doses of both alpelisib and placebo (inert non-drug) in random order (like flipping a coin) in study participants. Participants will be asked to stay twice overnight in the hospital, take single doses of alpelisib and placebo (one or the other on each of the two hospital stays), and receive intravenous (into the vein) infusions of non-radioactive "tracer" molecules that allow researchers to measure the production of glucose (sugar) and fats by the liver. Measurements will be done both overnight, while participants are asleep and fasting (not eating or drinking other than water) and while consuming a standardized diet of nutritional beverages during the following day. The objective is to evaluate the effect of lowering insulin levels, while maintaining constant mild hyperglycemia, on plasma glucose and lipid levels.
The aging population is rapidly increasing, and it is important to identify dietary factors that can prevent disease and promote health in this group. Legumes, such as peanuts, are a plant-based food high in protein and unsaturated fat making this a healthy choice, but are not consumed frequently enough in older adults. Studies have shown that regular nut consumption is associated with lower adiposity and reduced weight gain and inflammation. Given these findings, this study will examine the postprandial effects of meals with 2 levels of saturated fatty acids (SFA) on metabolic endotoxemia, inflammation and satiety, using a randomized cross-over design. The low SFA meal includes peanuts that are high in monounsaturated fatty acids (MUFA) and this will be compared to a high SFA meal. The results of this study have the potential to provide valuable insights into the role of peanuts in promoting health and preventing disease in at-risk older adults.
The CONNECT: "Developing a learning COmmunity to increase eNgagemeNt and Enrollment in cardiovascular Clinical Trials" is comprehensive, participant-centered learning community that provides tailored education on cardiovascular (CV) health and research participation; connects community members to CV-related research; and disseminates CV-related study findings. The overreaching goal of CONNECT is to improve participation of underrepresented communities in CV research, including as women, Black adults, and Latino adults, through increasing participants' clinical trial awareness, trust in biomedical research, and willingness to participate in clinical trials. CONNECT will use digital and community-engaged approaches to identify and recruit 1000 adults with cardiovascular disease or a cardiovascular disease risk factor to join CONNECT. Participants who join CONNECT will receive tailored educational information on CV health and research participation via text message. Participants will also have the opportunity to be matched to ongoing CV research studies based on basic demographic information and areas of interest. The educational information will be sent to participants for 12 months. The investigators hypothesize that CONNECT will increase participants' clinical trial awareness, trust, and willingness to participate in clinical trials and that the proportion of Black and Latin adults and women enrolled in trials that partner with CONNECT will be higher following the use of CONNECT for recruitment.
Obesity represents a serious global health issue with significant consequences, including an increased risk of chronic diseases. Statistics indicate a growing trend of obesity, highlighting the need to seek methods that improve fat tissue metabolism and reduce obesity-related complications. Previous research on animals has shown that betaine, a substance engaged in one-carbon metabolism, may enhance fat oxidation and lower adipose tissue. Therefore, the aim of the research will be to assess the impact of 8-week betaine supplementation on body composition and lipid metabolism markers, as well as expression of genes related to lipid metabolism, in a group of adult women with abdominal obesity. This study is designed in a placebo-controlled, double-blinded, randomized fashion. The participants will be overweight or obese pre-menopausal females. Upon enrollment, participants will be randomly assigned to one of two parallel groups: betaine (3g/d) or placebo. The supplementation period will last for 8 weeks. There will be three study meetings: T1 before supplementation, T2 after 4 weeks of supplementation, and T3 after 8 weeks of supplementation. Blood will be drawn and body composition measured, and adipose tissue biopsy taken at meetings T1 and T3. The T2 meeting will involve only body composition measurement. Study outcomes will include body mass and composition (including body fat percent), lipid profile, and the expression of genes related to lipid metabolism in adipose tissue and peripheral blood mononuclear cells.
Overweight and obesity are at epidemic proportions in the world population as well as in the United States, where nearly 42% of the adult population(1) is considered to meet the definition of obesity, namely a body mass index ("BMI") ≥ 30 kg/m2. Well-established links between obesity and increased morbidities and mortality make treatment of the utmost importance; however, there continues to be a significant unmet need for more effective treatments for obesity. Bariatric surgery is recognized as an effective treatment for obese patients, particularly in more severe cases where surgical restriction of the stomach's capacity and outlet size are considered necessary. The BariClip® is a laparoscopically implanted device for treatment of obesity and serves as an alternative to current existing technology for use in bariatric surgery. The BariClip® is a medical device, non-adjustable, resembling a clip that is placed parallel to the greater curvature of the stomach, causing restriction of the gastric lumen in a vertical fashion. This multi-center, randomized, moderate-lifestyle (program of diet and exercise) controlled pivotal study of the BariClip® device is intended to gather data to objectively support its safety and effectiveness for the treatment of obesity in adults and to ultimately support marketing authorization of this device as a viable alternative to existing bariatric surgical procedures. Specifically, this study aims to look at efficacy of the BariClip® device with regards to weight loss metrics and secondary health metrics and safety of the BariClip® device with regards to serious adverse events.
