Filter by:The specific aim of this study is to determine molecular pathways that differentiate metabolically healthy vs unhealthy human phenotypes, and to investigate the therapeutic potential of pro-resolving lipids. Investigators will recruit volunteers that are metabolically healthy or unhealthy that fall within three BMI ranges: lean (18.-24.9 kg/m2), overweight (25.0-29.9 kg/m2) and obese (>30.0 kg/m2). Investigators hypothesize that metabolically healthy individuals have a superior endogenous capacity to regulate an inflammatory/resolving response.
This study will look at how well CagriSema helps people with excess body weight lose weight. CagriSema is a new medicine developed by Novo Nordisk that combines cagrilintide and semaglutide. CagriSema cannot yet be prescribed by doctors. In the study, participant will either get CagriSema or dummy medicine and which treatment participant get is decided by chance. The study will last for about 1½ years for each participant.
Developing and validating a predictive model to estimate the risk of early biliary stasis following bariatric surgery
A body of animal studies as well as observational studies in humans demonstrated that butyrate is one SCFA that has pronounced positive effects on body weight control, inflammation, and insulin resistance. Even though the SCFA hexanoate is less researched, it has been shown to be involved in anti-inflammatory processes. Of note, acute human studies showed that fibre-induced metabolic improvements are linked to higher SCFA levels in the systemic circulation. It has been shown that a butyrate/hexanoate-enriched triglyceride oil enhanced systemic butyrate and hexanoate concentrations for a prolonged time. Yet, it remains to be determined whether a chronic increase in circulating butyrate and hexanoate concentrations translate into long-term benefits. In this study it is hypothesized that a chronic increase of butyrate/hexanoate in the circulation may improve host metabolism and metabolic health by improving adipose tissue function, reducing systemic lipid overflow and inflammation thereby increasing peripheral insulin sensitivity in individual with overweight/obesity and prediabetes.
Rare genetic forms of obesity, so called monogenic obesity are linked to alteration in energy balance involving hypothalamic pathways. More than 60 genes encoding for proteins located in the hypothalamic leptin/melanocortin pathway have been described in the French National Protocol for Diagnostic and Care (PNDS). The natural history of monogenic obesity is characterized by an early onset in childhood, with a major increase in weight in adolescence and young adulthood. The worsening of obesity exposes these patients to severe complications. Severe obesity and eating disorders have a major impact on the quality of life of the person but also of the family and caregivers. Clinical management is complex and requires comprehensive, specialized and multidisciplinary management. But the usual lifestyle approaches have so far shown disappointing results, similarly to bariatric surgery which leads to a more frequent weight regain in the situation of monogenic obesity, justifying new approaches. In this context, evaluating the response to treatment in the particular condition of monogenic obesity is crucial to propose therapeutic options as early as possible to limit weight evolution and its complications. GLP-1 (glucagon-like peptide 1) based innovative therapies have recently emerged as a promising option for treatment of obesity and its complications. This is the case for Semaglutide 2.4mg/week (WEGOVY®), developed by Novo Nordisk. However, there is a lack of data to confirm that semaglutide could be also effective in monogenic obesity. The hypothesis in this study is that treatment with Semaglutide 2.4mg/week (WEGOVY®) could be as effective in monogenic obesities as in common obesity.
This study aims to evaluate the effect of daily intake of a specific combination of different natural histidine-related amino acids in combination with dietary recommendations, in the reduction of visceral fat, as well as their associated comorbidities, in postmenopausal women with abdominal obesity.
Obesity and diabetes share a common insulin resistance pathway and contribute to chronic hyperglycemia. Both high-intensity interval exercise (HIIE) and focused ultrasound (FUS) have been explored in the context of managing insulin resistance in diabetic individuals with abdominal obesity, though they operate through different mechanisms and have different implications.
Metabolic dysfunction-associated steatotic liver disease (MASLD), formerly known as non-alcoholic fatty liver disease (NAFLD), a major global public health concern, is commonly associated with obesity, diabetes, and dyslipidemia. MASLD is currently the most common cause of chronic liver disease affecting about 80% of people with obesity, ranging from simple fat deposits in the liver to Metabolic Dysfunction-Associated Steatohepatitis (MASH), cellular injury, advanced fibrosis, cirrhosis, or hepatocellular carcinoma. Patients with MASH are also at risk for cardiovascular disease and mortality. There is no universally approved medication for MASH. Weight loss remains the cornerstone of MASH treatment. Patients meeting the inclusion and exclusion criteria and who give informed consent will be enrolled in the trial and undergo the baseline liver biopsy (if none available). Approximately 120 patients with MASH and liver fibrosis (F1-F4 in baseline liver biopsy) will be randomized in a 1:1 ratio to metabolic surgery or medical treatment (incretin-based therapies ± other medical therapies for MASH) and followed for 2 years at which time a repeat liver biopsy will be performed for the assessment of the primary end point.
This 12-week pilot study aims to evaluate the feasibility and effectiveness of a dietary intervention targeting diet, obesity, mental health, and the gut microbiome in promoting weight loss and enhancing mental health among obese men and women aged 30-50. Participants, excluding those with specific medical conditions, will be randomly assigned to either an intervention or control group using a meal planning smartphone app. Clinical assessments will include anthropometry, mental health questionnaires, dietary recalls, and stool sample collections. The study's endpoints include program retention, adherence, changes in body weight, mental health, and gut microbiome diversity. Statistical analyses will evaluate intervention effects and the potential mediating roles of the gut microbiome. This pilot study has implications for health policies, public healthcare, digital health companies, and the biotech and pharmacology industries. Future plans involve a large-scale intervention study in multiple countries with ongoing collaborations.
Obesity is a chronic disease characterized phenotypically by an increase in body weight (BMI>30 kg/m2) and by a series of associated pathologies, such as hypertension, diabetes, hepatic steatosis. The association of these pathologies compromises the patient's survival and quality of life. The multifactorial origin of obesity makes its etiopathology difficult to manage. It is often possible to follow only one therapeutic strategy, especially after the so-called standard treatments, such as dietary intervention and physical activity, have not brought benefit to the patient. In these cases, an appropriate treatment for the patient to enjoy significant weight loss is bariatric surgery. Bariatric surgery refers to all those interventions aimed at reducing weight in those suffering from obesity, and treating the diseases associated with it. Among the different types of bariatric surgery, the techniques most used in common clinical practice are intragastric balloons, gastric by pass (RYGB) and sleeve gastrectomy. The choice of the surgeon, assisted by the multidisciplinary team, is binding in the choice of the type of operation to which the patient will be subjected.
