Filter by:The aim of this study is to acquire impedance measurements of the adult human body with a novel bioimpedance device housed inside a watch case and to compare derived estimates of body composition measured by dual-energy x-ray absorptiometry (DXA) and other bioimpedance analysis (BIA) systems.
The purpose of this study is to evaluate safety and efficacy of twice-daily ARD-101 in subjects at least one year after bariatric surgery (sleeve gastrectomy or gastric bypass).
This pilot study is an active control randomized controlled trial with a sample size of 30 that will consist of 2 groups, to evaluate the effects of a one-month alternate day intermittent energy restriction (AltER) intervention on body weight, body composition, resting metabolic rate in college students with obesity as compared to a standard reduced calorie diet (RCD). Among the 30 participants, 15 will be randomized into the experimental group that will receive the AltER intervention while the other 15 will be a part of the active control group that will follow a RCD. The study will be conducted at the Texas Tech University Nutrition and Metabolic Health Initiative.
With the prevalence of obesity soaring and the absence of an effective and safe treatment that is low-cost and always feasible, the use of food supplements has gained attention for the potential benefits in the absence of significant safety concerns. Cinnamon (CC) and Withania somnifera (WS) are plant-based supplements reported to be effective in improving metabolic health and body composition, the first mainly acting on insulin resistance and the second on energy expenditure and leptin resistance, as shown in preclinical and some clinical studies. Their association, possibly synergistic leveraging different mechanisms of action, has never been studied. This was a double-blind placebo-controlled study. Patients with overweight or obesity were prescribed a mildly hypocaloric diet with CC 300 mg plus WS 150 mg tid for 4 weeks in a cross over design and anthropometric parameters together with safety outcomes were collected.
Obesity is defined as the accumulation of excessive fat, attributed to the maintenance of a positive energy imbalance between calorie intake and expenditure. Obesity contributes to the development of many comorbidities such as type 2 diabetes, cardiovascular diseases, hypertension, metabolic syndrome, and dyslipidemias, among others. Dyslipidemias indicate a high concentration of lipids in the blood. Dyslipidemias cause more than 4 million premature deaths per year. The pathogenesis of obesity is complex as it involves environmental, sociocultural, physiological, medical, behavioral, genetic, epigenetic, and many other factors. On the other hand, the causes of dyslipidemias can be: genetic / hereditary (primary dyslipidemias) or an inadequate lifestyle (secondary dyslipidemias). Sufficient evidence indicates that lifestyle, mainly diet, plays a decisive role in the development of diseases such as obesity and dyslipidemias, in addition to that, recent research shows the importance of individual genetic predisposition to suffer from diseases. Data based on genome-wide association studies suggest a genetic predisposition for obesity and dyslipidemias with identification of various genes and genetic variations associated with these conditions. In this sense, the postulates of nutrigenetics as applied science are emphasized, since it states that food components can act on the human genome, directly or indirectly, to alter the expression of genes and gene products; diet can potentially compensate or accentuate the effects of genetic polymorphisms; and the consequences of a certain diet depend on the balance of health and disease states and the genetic background of an individual. Therefore, when advising a change in diet and lifestyle as prevention and as part of the treatment for obesity and dyslipidemias, it is considered that a nutrigenetic intervention, that is, the administration of a diet designed according to genotypic characteristics and personal phenotypic, will have a much greater positive impact on the health status of people with detected genetic variations that make them susceptible to these pathologies. For this reason, the implementation of nutrigenetic interventions could be a timely and successful avant-garde treatment to mitigate various cardiometabolic diseases such as dyslipidemias and others that are highly prevalent worldwide.
To determine the effect of aerobic exercise training on arterial stiffness and hemodynamics in obese adults. Proper evidence on the effect of aerobic exercise training on both arterial stiffness and hemodynamics are sparsely present in obese adults whereas separate studies were done in mainly hypertensive and cardiovascular disease populations.
Over 70% of U.S. adults have overweight or obesity. Currently, the most efficacious behavioral intervention for obesity is standard behavioral treatment (SBT), often composed of group sessions, calorie goals, and physical activity goals. With this approach, participants often lose 8-10% of the person's baseline weight, and also decrease risk for cardiovascular disease. Long-term weight loss, however, is limited; many participants return to baseline weight within five years following treatment. One reason SBT may not create long-term weight loss may be due to treatment components that teach participants to rely on external methods for changing eating decisions (e.g., counting calories, restricting certain foods), rather than internal cues of hunger and satiety. Because individuals with obesity report significant challenges with adhering to these cues, augmenting behavioral interventions with appetite self-regulation training may be a solution. Thus, the investigator propose to examine the feasibility and acceptability of a 6-month remotely-delivered appetite regulation + lifestyle modification intervention to treat obesity.
The benefits of nutritional interventions with dietary restrictions are associated with improvement and preservation of mitochondrial function. Evidence suggests that dietary restrictions, including modifications in caloric intake (caloric restriction), or in the timing of food intake (e.g., intermittent fasting), play an important role in stimulating cell and mitochondrial autophagy, favoring the elimination of old and dysfunctional mitochondria. In addition to the observed effects on mitochondrial function, there is evidence that intermittent fasting, caloric restriction, and the ketogenic diet also generate changes in gut microbiota and microbial metabolite composition. The main aim of this study is to evaluate the effect of intermittent fasting, caloric restriction and ketogenic diet on mitochondrial function determined by respirometry in monocytes, modulated by the gut microbiota in subjects with obesity. An open randomized controlled clinical trial will be conducted with 80 participants divided by a draw in 4 nutritional interventions groups for 1 month, each for 20 participants, then participants will receive 550 mg of rifaximin and will finish the study with the assigned nutritional intervention for another month of follow-up. Knowledge of these dynamics will allow us to explore and understand the relationship between metabolites from the gut microbiota and their effect on mitochondrial function associated with the dietary interventions mentioned above.
1. Study Objective - To assess the effect of HSG4112 on body weight - To evaluate the safety and tolerability of HSG4112 2. Background Glaceum Inc. has evaluated the safety, tolerability, and pharmacokinetic/pharmacodynamic properties of HSG4112 in healthy subjects through its Phase 1 trials, and is planning to perform this Phase 2a trial to assess the safety and efficacy of HSG4112 in overweight and obese patients. 3. Number of Subjects This study is a Phase 2a clinical trial designed to evaluate the safety and efficacy of HSG4112 following multiple-dose administration. The subject sample size estimate for the primary efficacy endpoint was based on total body weight, and assumes repeated measurement of body weight occurs at Baseline and every 4 weeks thereafter during the 12-week treatment period. Based on similar weight loss studies with obesity drugs, the covariance matrix for body weight change over time is estimated as AR(1) (sigma = 3.07, rho = 0.9). Thus, with 20 subjects completing each treatment group, this study can detect a mean difference of 6 kg between HSG4112 and matching placebo treatments with 80% power, assuming a two-sided α-level of 0.05. Therefore, the target sample size for this study is 20 subjects/group. 4. Study Design and Protocol This study is a randomized, double-blind, placebo-controlled, parallel-groups trial. Subjects deemed eligible to participate in this study based on the inclusion/exclusion criteria will be assigned a subject number and randomized to one of the 4 treatment groups - 1 group receiving placebo - in a 1:1:1:1 ratio. Subjects will be randomized to double-blind treatments and will receive a once-daily oral dose of the investigational product for 12 weeks according to the study protocol. Body weight and obesity/metabolism-related parameters will be evaluated to assess the efficacy of HSG4112. Assessments including measurement of vital signs, 12-lead ECG, clinical laboratory tests, pregnancy test, physical examination, and adverse event monitoring will be performed to evaluate the safety and tolerability of HSG4112. Blood samples will be collected for pharmacokinetic assessment and samples from subjects who have signed the consent form for the exploratory genetic research will undergo analysis to detect PON2 gene polymorphism.
