Effects of Multi-strain Bacillus Spore Probiotics on Growth, Digestive Function, and Gut Microbiota in Cesarean-Delivered Neonates

Infants born by cesarean section commonly show early weight loss and slower recovery of birth weight, together with characteristic patterns of gut microbiota dysbiosis marked by reduced Bifidobacterium and Bacteroides and increased Proteobacteria. This early microbial alteration has been associated with functional gastrointestinal disorders (FGIDs), including colic, regurgitation, and changes in stool frequency and consistency, which may in turn affect early growth and overall gastrointestinal functioning. Probiotic supplementation is considered a safe and feasible strategy to support microbial restoration and improve digestive function during the first months of life. In this study, researchers propose that daily supplementation with multi-strain Bacillus spore probiotics may help support healthy early growth, reduce functional gastrointestinal symptoms, and promote a more balanced gut microbiota in cesarean-delivered infants. The objective of this study is to evaluate the safety and efficacy of two oral probiotic formulations, LiveSpo PREG-MOM and LiveSpo CONSY, containing multi-strain B. subtilis ANA46, B. clausii ANA39, and B. coagulans ANA40 at respective 3 and 4 billion colony-forming units (CFU)/5 mL ampoule, administered 1 ampoule daily, during the first 90 days of life. The study examines effects on growth, digestive symptoms, immune markers, and microbial composition. Study Design: This randomized, blind, controlled clinical trial will enroll 180 healthy full-term cesarean-born infants at Hanoi Obstetrics and Gynecology Hospital. Intervention Description: Participants will be randomly assigned to three groups (n = 60 each). All groups will receive one 5-mL ampoule daily for 90 days: LiveSpo PREG-MOM, LiveSpo CONSY, or placebo. Stool samples will be collected at several follow-up time points to assess digestive health and microbial development. All products will be provided in blinded and coded packaging to maintain objectivity. Study Duration: 12 months

The Role of Microbiome in Recurrent Obesity Before and After Antibiotic/Placebo Treatment

This past century witnessed a significant increase in the prevalence of obesity. Successful weight loss maintenance is defined as losing at least 10% of the initial body weight and maintaining it for at least one year. However, keeping a low body weight is rarely maintained, as 80% of people who lost 10% of their body weight will return to their initial weight within a year. Although there is no agreement as to what contributes to the recurrent weight regain phenomenon (also known as 'weight cycling' or 'yo-yo diet'), it is strongly associated with the risk of developing metabolic risk factors and their complications, including heart disease and all-cause mortality. Altering the gut microbiota is one method to treat disease states associated with gut bacteria. Antibiotics consumption is known to influence host glycemic response through changes induced in microbiome composition and function. Therefore, it may be a possible pathway to jumpstart changes in the gut microbiota. This study will determine whether microbiome modulation might be a possible future target against recurrent obesity in humans and whether orally administered antibiotic treatment post-weight loss might be an effective intervention to prevent weight regain.

Reset: Enhancing Weight Loss in a Digital Intervention

The goal of the Reset trial is to learn about the optimal combination of dietary behavior strategies in a fully digital weight loss intervention. The intervention is designed for adults with overweight or obesity. The investigators will examine the impact on weight loss of four dietary strategies: 1) limiting Red Zone Foods (i.e., foods that are high in calories and low in nutrition), 2) limiting eating windows, 3) increasing protein intake, and 4) increasing fiber intake. Each of these strategies will include goal setting, daily self-monitoring, and tailored feedback. The investigators will recruit 208 participants. Broadly, adults with overweight or obesity who live in the U.S. will be eligible. The weight loss intervention will last 12 weeks. All participants will be asked to track their body weight daily and complete weekly behavioral lessons and action plans to promote healthy eating and physical activity. All study tasks will occur remotely. Assessment of body weight and survey measures will occur at the beginning of the trial ("baseline"), and at 1 month and 3 months. The Multiphase Optimization Strategy (MOST) framework will be used to identify which combination of the dietary behavior strategies results in the greatest weight loss. In total, there will be 16 treatment conditions.

Mitigation of Cardiovascular Disease Risks in Children With Extreme Obesity

The goal of this clinical trial is to learn if the drug semaglutide changes markers of disease risk as it relates to weight in children ages 12-15 years old who are obese (class 2 or 3). The main questions it aims to answer are: * How do the rate of weight loss, body mass index (BMI), body composition, heart structure and function, and exercise ability interact with one another in the study population at enrollment? * How do risk markers of disease change over the study in the study participants who are given semaglutides to help with weight loss? * Are there differences in the above factors between males and females and are there key factors to help improve the outcomes? Participants will be given semaglutide for this study. During the course of the study, participants will: * have two cardiac MRI scans OR two cardiac echocardiograms (one before starting semaglutide and one around 12 months after taking the drug) * have body composition and fitness levels assessed twice (before semaglutide and around 12 months after taking it) and have urine specific gravity (USG) measured * have extra blood drawn when labs their doctor orders are already being drawn (once at the beginning of the study, once around 6 months after enrollment, and once at the end of the study) * have follow up visits with the study doctor * be asked to take a pregnancy test if they are female and have started menstruation

Effects of GLP-1 RAs on Human Lactation Outcomes

There is increasing interest in using GLP-1 Receptor Agonist (GLP-1 RA) medications after pregnancy. This study is designed to determine if these medications affect breastmilk production or the nutritional makeup of breastmilk. The main questions the study will address are: * Does GLP-1 RA-induced weight loss increase or decrease breastmilk production? * Does GLP-1 RA-induced weight loss affect the nutritional composition of milk, including milk fat content? Researchers will assess milk production rates before and after mothers begin taking injected GLP-1 RA medications to decrease their body weight. Weight loss will be confirmed with 7-day body weight averages. Participants will: * Weigh themselves and report measurements daily. * Participate in 2-3 morning study visits over approx. 2.5-4.5 months (approx. 3-3.5hrs each). During each visit, participants will: * Use a study provided breastpump to express milk 3 times hourly for measurement of hourly milk production. * Provide 1-3 oz of milk for further study. * Answer questions about breastfeeding patterns.

Effect of Endoscopic Sleeve Gastroplasty in Patients With Obesity and MASH: A Randomized Controlled Trial

Metabolic dysfunction-associated steatotic liver disease (MASLD) is the most common chronic liver disease globally. While weight loss through lifestyle modification is the standard treatment, most patients regain weight limiting ultimate improvement in liver disease. On the other end of the spectrum, bariatric surgery has shown promise in the treatment of MASLD/metabolic dysfunction-associated steatohepatitis (MASH) due to its efficacy in inducing weight loss. Nevertheless, its adoption has been hindered by the perceived invasiveness of surgery. Over the past decade, endoscopic sleeve gastroplasty (ESG) has gained recognition as a promising minimally-invasive approach to weight loss. The procedure involves utilizing a Food and Drug Administration (FDA)-authorized endoscopic suturing device to reduce the gastric volume by 70%. Studies reveal that ESG is associated with approximately 18.2% weight loss at one year after the procedure, with sustained results for at least 10 years. Nevertheless, the effect of ESG on MASH remains unknown. In this study, the investigators will compare ESG + lifestyle modification versus lifestyle modification alone in treating histologic MASH. The study will randomize patients to one of two different treatment options: ESG + lifestyle modification or lifestyle modification alone.

Effect of Weight Loss on Physical and Cardiac Performance in People With Obesity and Heart Failure

The benefit of weight loss in patients with obesity and heart failure with reduced ejection fraction (HFrEF) is controversial. Semaglutide has shown cardiovascular (CV) risk-reduction and impact on CV risk factors including overweight, dysglycaemia and hypertension in subjects with type 2 diabetes (T2D). The STEP-HFpEF (Semaglutide Treatment Effect in People With Obesity and HFpEF) recently demonstrated, at 1-year, to not only reduce weight considerably, but also significantly improve health-related quality of life, functional status scores and 6-min walk distance in patients with heart failure with preserved ejection fraction (HFpEF). Also, the recently concluded SELECT trial was the first CV outcome trial with semaglutide in patients with overweight or obesity and established CV disease, including heart failure (but no T2D). Semaglutide demonstrated a 20% reduction in MACE, defined as the composite of cardiovascular death, non-fatal myocardial infarction, and non-fatal stroke. These landmark findings have important implications for clinicians -as they mean that weight loss and/or semaglutide as anti-obesity pharmacotherapy could be a treatment strategy for secondary prevention of CV disease in patients with overweight or obesity. It is, however, unknown whether weight loss with either calorie-restricted diet or semaglutide has beneficial effects in obese subjects with heart failure and reduced ejection fraction. Also it is unclear whether semaglutide has cardiovascular benefits irrespective of starting weight and amount of weight loss. Purpose: The study aims to investigate whether weight loss treatment with semaglutide is superior to weight loss with calorie-restricted diet in improving peak oxygen uptake in patients with obesity and heart failure with reduced ejection fraction.

Simplifying Diet Tracking in a Digital Weight Loss Intervention

The purpose of this study is to compare two approaches for tracking dietary intake in a 12-month fully digital weight loss intervention: (1) Simplified approach: track Red Zone Foods (e.g., foods high in calories and low in nutritional value) vs. (2) Detailed approach: track all foods and their corresponding calories. In essence, this is a head-to-head comparison of two tracking approaches; the investigators are evaluating whether weight loss is comparable over 12 months, or whether one approach will have greater weight loss. The investigators will recruit 328 adults. Broadly, adults with overweight or obesity who live in the United States will be eligible. The weight loss intervention will last 12 months. All participants will be asked to track their dietary intake + body weight + steps daily as well as complete weekly behavioral lessons and action plans to promote healthy eating and physical activity. All study tasks will occur remotely. Assessment of body weight and survey measures will occur at the beginning of the trial ("baseline"), and at 1, 6, 12, and 18 months.

Metabolic Health, Bones and Nuts During Weight Loss in Adults

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 several dietary pattern studies indicate that nuts and legumes are associated with better bone health. In addition, our preliminary translational data indicates that a higher monounsaturated fatty acid (MUFA) intake is associated with improved bone mineral density (BMD) and quality. Given these findings, the proposed study aims to examine the impact of consuming peanut products on bone health, metabolic health (e.g., serum glucose, insulin, lipids and inflammation), markers of brain and sleep health, and physical function in overweight and obese older adults before and after a six-month weight loss intervention using a randomized controlled design. The results of this study have the potential to provide valuable insights into the role of peanuts as a sources of fatty acids in promoting health and preventing disease in at-risk adults.

Adipocyte-Derived Extracellular Vesicles, Weight Loss, and Endothelial Function

Changes in adipose tissue biology are now recognized as a key factor underlying the increased risk of metabolic and cardiovascular disease with obesity. Clinical interest in adipocyte-derived extracellular vesicles (Ad-EVs) has intensified due to their potential as circulating biomarkers of adipose tissue health and systemic messengers, regulators and mediators of cardiometabolic health and disease with obesity. The investigators hypothesize that elevated Ad-EVs in adults with obesity will be negatively associated with endothelium-dependent vasodilation. Furthermore, the investigators hypothesize that in adults with obesity, intentional weight loss-induced reduction in circulating Ad-EVs is associated with greater endothelium-dependent vasodilation.
