Sanctuary Farm Prescription in Adolescents

The goal of this research study is to learn if an 8-week produce prescription program (in partnership with a local urban farm) can increase fruit and vegetable consumption in overweight teens and improve their blood pressure and weight. The main questions are: * Is a produce prescription program in overweight teens feasible? * Will a produce prescription with educational videos increase weekly fruit and vegetable intake? * Will a produce prescription with educational videos improve blood pressure and weight for height? Researchers will compare the teens' fruit and vegetable intake, blood pressure and weight for height before and after the produce prescription. Researchers will also see how feasible it is by measuring the number of produce prescriptions are picked up by the families and how many educational videos are viewed. Participants will: * complete questionnaires related to their diet and nutrition * measure their blood pressure and weight at the beginning and end of the study * obtain weekly produce prescriptions

Training App for Inhibitory Control Towards Food

The aim of this project is to test the feasibility, acceptability and clinical impact of a mobile app-based intervention (FoodTraining) to strengthen food-related inhibitory control over 4 weeks, in a sample of people with eating or weight disorders (i.e. obesity, binge-eating disorder (BED), or bulimia nervosa (BN)) receiving standard outpatient treatment (i.e., treatment as usual (TAU) encompassing guided self-help or psychotherapy, pharmacological therapy or diet). The training will be offered in addition to TAU (experimental group) and compared to TAU alone (control group). Participants will complete questionnaires to measure eating behaviour, eating disorder psychopathology, symptoms of anxiety, depression and stress, social functioning and quality of life at baseline, 4 and 8 weeks. They will also complete momentary assessments using a mobile application (FoodTracker) to report on food intake along with related thoughts, emotions, and behaviours and will wear small, non-invasive sensors to track real-time fluctuations in glucose levels for 15 days. Participants will also perform a food-related go-no go task and a food-related temporal discounting task at baseline, 4 and 8 weeks. Finally, this study will pilot the use of a semi-structured interview to characterise the history of weight, the appetite system, eating-related habits in the family and learning of eating behaviours and attitudes in people with eating or weight disorders.

Evaluating the Impact of GLP-1 Receptor Agonists With Total Neoadjuvant Therapy in Rectal Cancer

The goal of this clinical trial is to see if adding a weight loss medication (GLP-1 receptor drug) to patients with an increased BMI receiving treatment for rectal cancer prior to surgery (total neoadjuvant chemoradiotherapy) improves cancer outcomes. The main questions it aims to answer is 1. Does the drug increase weight loss in rectal cancer patients with a high BMI 2. Does the drug improve response rates to chemotherapy and radiotherapy 3. Does the drug improve survival outcomes and if cancer returns Researchers will compare this drug in one group against a group of patients receiving preoperative total neoadjuvant chemoradiotherapy without the drug Patients will be required to 1\) take the GLP-1 receptor agonist drug during TNT or just having TNT alone as per standard hospital protocols Body weight will be measured at three predefined time points: 1. Baseline: Prior to initiation of semaglutide or TNT 2. Pre-TNT: Start of TNT (for the intervention arm, this is 4 weeks after semaglutide initiation) 3. Post-TNT: Within 7 days following completion of TNT and prior to definitive surgery Patients will complete their treatment and go on to have surgery as per standard methods for treating rectal cancer

A Prospective Randomnised Controlled Trial Comparing Overall Patient Compliance in a Bariatric Surgical Pathway Using the Standard Versus a More Intensified and Interactive Version of the "Get Ready" Smartphone Application.

The aim of this study is to assess the impact of a newly intensified digital platform following bariatric surgery. This will be measured using several questionnaires. The following objectives will be evaluated: the exact amount of weight loss achieved preoperatively with the preparatory diet; the occurrence of dumping symptoms; the assessment of quality of life (QOL); and compliance with supplement intake. By examining the impact of an enhanced digital platform, we aim to address critical questions regarding the effectiveness of improved patient support in the digital domain. Moreover, given the increasing prevalence of bariatric surgery as a therapeutic option for obesity, it is of utmost importance to identify strategies to optimize patient education and support through digital tools. This study not only contributes to the scientific understanding of digital support in bariatric care but also has important implications for the further development of the "Get Ready" application, ensuring that it remains at the forefront of providing comprehensive and patient-centered support in the evolving landscape of bariatric surgery.

Spontaneous Breathing Trials Using Pressure Support or T-Piece in Overweight and Obese Patients

This study aims to find out which method of spontaneous breathing trial (SBT) better helps overweight and obese ICU patients prepare for extubation, which is the removal of the breathing tube. The two methods being compared are pressure support ventilation (PSV) and the T-piece. Participants are adults with a body mass index (BMI) of 25 or higher who have been on a breathing machine (invasive mechanical ventilation) for more than 24 hours. Before removing the breathing tube, participants will be randomly assigned to receive either a PSV or a T-piece trial for 1 hour. After that, doctors will decide if they are ready for extubation. The main question this study wants to answer is: Which method leads to a higher rate of successful extubation-defined as not needing to be reintubated within 72 hours?

Probiotic Intervention for Digestive Health in Obese Patients Initiating GLP-RA Treatment

Obesity is a prevalent chronic disease affecting 17% of the French population. Treatment involves multiple factors, with pharmacotherapy playing an increasingly important role. GLP-1 receptor agonists (GLP1 RAs) are considered revolutionary in obesity treatment, with three approved molecules available in France: liraglutide, semaglutide, and tirzepatide. These treatments, combined with a healthy lifestyle, induce significant weight loss: 9% with liraglutide, 15% with semaglutide, and 20% with tirzepatide. The most common adverse events (AEs) associated with GLP-1 RAs are gastrointestinal (GI) disorders, including nausea, vomiting, diarrhea, and abdominal pain. These AEs are dose-dependent and often decline over time. In phase 3 trials, semaglutide 2.4 mg showed higher rates of GI AEs compared to placebo, but most were mild to moderate and transient. GI AEs led to dose reduction or temporary treatment interruption in 12.5% of participants, with few permanent discontinuations. Probiotics, are live microorganisms that benefit the host by improving gut microflora. Probiotics has been clinically proven to benefit gastrointestinal health. Probiotics may reduces symptoms of irritable bowel syndrome (IBS), improves gut barrier function, reduces inflammation, and decreases the incidence of C. difficile infection (CDI) in patients taking antibiotics. Probiotics is therefore theorized to potentially reduce GI side effects associated with GLP-1 RA treatment for obesity. Hypothesis Probiotics will prevent and limit the digestive disorders induced by GLP-1 R agonists, particularly during the dose escalation period. This would allow better digestive tolerance of the treatments, limiting the number of definitive treatment interruptions, facilitating compliance and dose escalation with a larger number of subjects at full dose and therefore with better systemic exposure to the compounds, a key factor in their effects on weight loss.

Validation of Heart Rate Monitors in Overweight and Obese Young Adults

Overweight and obesity are defined as an excessive accumulation of body fat that affects health. According to data from the World Health Organization (WHO), in 2022, there were 2.5 billion adults aged 18 years and older who were overweight, of whom 890 million were obese. In other words, 43% of adults aged 18 years and older were overweight, and 16% of them were obese. Overweight and obesity are key risk factors for various chronic diseases such as diabetes, hypertension, cardiovascular disease, and even some types of cancer. There is evidence that mortality from cardiovascular disease, and the incidence of cancer and diabetes, varies according to the amount of physical activity. In the context of high levels of sedentary time, higher levels of moderate to vigorous physical activity are recommended. There are various ways to treat overweight and obesity, the main ones usually being lifestyle changes, such as following a healthy diet and regular physical activity, as well as following pharmacological treatments. In this project, the focus will be on the fat metabolism generated during moderate physical activity. There are physical activity interventions aimed at increasing fat metabolism that may potentially reduce the symptoms of metabolic diseases such as obesity and type 2 diabetes. For this purpose, it is important to understand the factors that increase or decrease fat oxidation. Factors such as exercise intensity and duration are important to understand when determining maximum fat oxidation (FatMax). The aim is to develop comprehensive research that will generate knowledge and evidence on health issues with social impact through the evaluation of commercial technologies and innovative actions that promote the prevention, treatment, and resolution of national health problems such as obesity.

Studying the Influence of LEAP2 on Integrated Endocrine Control of Eating During Semaglutide Treatment

This clinical study investigates how blocking the hunger-related ghrelin receptor affects appetite and metabolism in individuals with obesity who are treated with semaglutide (a GLP-1 receptor agonist). LEAP2, a naturally occurring hormone that inhibits the ghrelin receptor, is used as the investigational compound. The objective of the study is to clarify how the ghrelin system functions when appetite is suppressed by semaglutide treatment. Participants will receive either LEAP2 or placebo during two experimental visits in a randomized, double-blind, crossover design. The investigators will assess food intake, appetite sensations, glucose metabolism, and hormonal responses. By examining the interaction between semaglutide and ghrelin signaling, the study aims to improve understanding of how multiple appetite-regulating systems interact and whether additional hunger signals remain active during GLP-1 treatment. The findings may inform the development of future treatments for individuals with obesity.

Effectiveness of a Family Support Model for Prevention and Management of Overweight and Obesity in Children 6-12 Years

The study will evaluate a coherent model of family support including school health care, primary health care and pediatric clinics. The model combines two evidence based programs: the universal "A Healthy School Start" provided to all children and their families during grade 1 and the targeted parental support program "More and Less" provided to parents of children with overweight or obesity. The hypothesis is that combining the Healthy School Start and More and Less programs in a coherent model will increase the collaboration between regional and municipal stakeholders, ensure early identification of families in need, ultimately improving prevention and treatment of childhood overweight and obesity. The aim of this study is to evaluate the implementation of a coherent model of family support provided through school and primary health care.

The Impact of a Weight Reduction Intervention on Clinical Outcomes in Patients With Obesity and COPD

Obesity and COPD are increasingly common and often coexist, worsening health outcomes such as reduced lung function, exercise capacity, and increased systemic inflammation. While COPD was historically associated with underweight, obesity is now more prevalent among these patients and poses new challenges. Despite some evidence that weight loss may improve lung function, comprehensive interventions have not been fully studied. The TRIO-COPD study aims to evaluate a 20-week program combining energy restriction, adequate protein intake, and structured exercise in COPD patients with obesity. The study will assess: Primary outcome: -Exercise capacity (6-minute walking test). Secondary outcomes: -Lung function (spirometry and lung volumes), -symptoms ( assessed via questionnaires), body composition (fat mass, fat-free mass, waist circumference), and inflammatory markers (e.g., IL-6, CRP, CC16). A subgroup will also undergo sputum analysis. The study addresses a critical gap, aiming to determine whether structured weight reduction can improve COPD symptoms, reduce inflammation, and limit muscle loss-advancing understanding of obesity's impact on COPD and providing evidence for potential treatment guidelines.

Fueling Strong Hearts for a Strong South Carolina

South Carolina is home to many survivors of stroke. After leaving the hospital and finishing therapies, stroke survivors often do not have the supports they need to fully recover. Many live with problems for a long time after their stroke, such as trouble walking or doing everyday tasks like cleaning, grocery shopping, or cooking. Research suggests that healthy habits, like moving more, eating well, and being at a healthy weight, can improve most of these disabilities. These habits can be hard to form alone though, especially in rural areas that may not have many healthy foods or places to exercise. Research-based programs can help people form healthy habits. These programs have not been tested in stroke survivors who have different needs though. The goal of this research project is to test StrongPeople StrongHearts, a health program, to see if it helps stroke survivors in South Carolina make better choices for their health and improve their quality of life. The program will be delivered online so that survivors in rural areas can be in the program. One group will also receive a weekly grocery box tailored to their needs to improve access to healthy foods. This study could help increase access to research-based programs for stroke survivors who do not have the supports they did soon after their stroke. This step is important for stroke survivors' long-term health and quality of life, the mission of the American Heart Association.

The MB-EAT Smart Teen Study

This two-phase, double-blind, balanced, parallel-group randomized controlled trial evaluates the feasibility, usability, engagement, and clinical impact of an app-based adaptation of the Mindfulness-Based Eating Awareness Training (MB-EAT) program for adolescents living with obesity. MB-EAT, has been shown to reduce binge eating episodes, improve food-related self-control, and decrease depressive symptoms in adults with obesity. The app based program promotes mindful awareness and self-regulation in response to hunger and satiety cues, without caloric restriction. Youth aged 12-17.5 years who are waitlisted or have recently been waitlisted for treatment at the Centre for Healthy Active Living (CHAL) at the Children's Hospital of Eastern Ontario (CHEO) will be enrolled in a 4-week app-based MB-EAT program (Phase 1, n=10) to evaluate feasibility, usability, and engagement. Phase 2 is a 12-week randomized controlled trial with 160 participants who will be randomized to the experimental arm (app-based MB-EAT program; 60-90 minutes/week) or an active comparator arm (app-based psychoeducation) to evaluate whether the MB-EAT program improves disinhibited eating. At the end of the intervention, 20 participants will be randomly selected for interviews to explore their experiences with the app. Additional secondary outcomes in Phase 2 include depressive symptoms, anxiety symptoms, emotion regulation, dispositional mindfulness, food craving, mindful eating, body image, health-related quality of life, impact of weight on quality of life, internalized weight bias, food impulsivity, and food reinforcement.

PHArmaCokinetics of methYLphenidate in Adult Patients With Attention-Deficit /Hyperactivity Disorder

PHACYLOB PHArmaCokinetics of methYLphenidate in adult patients with Attention-Deficit Hyperactivity Disorder (ADHD) : comparison between patients with and without OBesity. Its aim is to determine whether, for a comparable treatment dose, there are differences in the pharmacokinetic of methylphenidate between ADHD patients with obesitý and ADHD patients but without obesitý. More specifically, we will assess whether blood concentrations of methylphenidate (MPH; long acting form) are significantly higher or lower in either group at different times of the day. To meet this objective, we are conducting this pharmacokinetic clinical trial with blood sampling and repeated clinical measurements just prior to MPH administration (= at T0) and then, at different times after administration, i.e. at times (T): T 30 minutes, T 1 hour, T2h, T3h, T4h, T6h, T8h after MPH administration. As far as MPH is concerned, this is the usual treatment. However, we may hypothesize that the distribution in the body may differ according to weight: hence the interest of this study

Evaluation of the Care Provided to Patients Who Underwent Bariatric Surgery and Were Lost to Follow-up 5 Years After Surgery

In 2025, bariatric surgery combined with nutritional and psychological support is one of the most effective treatments for patients with morbid obesity. (2)(3) However, it causes various deficiencies, such as vitamin and iron deficiencies, which justify lifelong personalised vitamin supplementation and, consequently, lifelong medical supervision. The latest recommendations from the French National Authority for Health (Haute Autorité de Santé) clearly state that patients must commit to lifelong medical follow-up after bariatric surgery. (HAS, February 2024, R94). R94. Regular biological monitoring after bariatric surgery is recommended: three times in the first year and then once or twice a year thereafter. Within the OBESEPI cohort (clinical trial number NCT02663388), which comprises patients who underwent surgery at Nancy University Hospital between 2013 and 2018, we observed that over 50% of patients were lost to follow-up five years after surgery.

Proof of Concept in the Prevention of Post-bariatric Sarcopenia: Simulated Activation of the "Gravitostat"

Due to its mechanical and metabolic functions, muscle loss leads to resistance to weight loss during caloric restriction, particularly in patients with obesity. The recent discovery of a "gravitational" homeostatic system, induced by an additional load to body weight, suggests the existence of a new weight control mechanism. Such a "gravitostat" would ensure a form of weight homeostasis mediated by afferent signals originating from osteocytes in response to gravity perception. This hypothesis, initially derived from animal studies, has more recently been tested in humans. It shows that "activation of the gravitostat" through artificial increases in body weight facilitates body weight reduction without affecting lean mass (LM). Therefore, this "gravitostat" could contribute to preserving LM despite the loss of fat mass , whereas its decline may compromise muscle mass and function after bariatric surgery, despite undeniable improvements in comorbidities. The present study aims to reduce the "metabolic load" (i.e., decreasing insulin resistance and inflammation) to promote muscle protein anabolism, while maintaining the "mechanical load" (by preserving initial body weight during weight loss induced by bariatric surgery) in order to activate the "gravitostat" and preserve muscle mass and function. Currently, there are no clear recommendations or strategies to prevent muscle loss in patients who have undergone bariatric surgery. This simple concept, applied during drastic muscle loss, should help improve muscle health.
