Active clinical trials for "Obesity"

About 380 million children and adolescents suffer from overweight and obesity at the global level. Obesity results from the interplay between biological (sex, age, fetal programming, gut microbiota, epigenetics, and genetics) and environmental factors (e.g., unhealthy diet, physical inactivity, stress). Mutations in genes from leptin melanocortin pathway are involved in "non syndromic monogenic obesity", characterized by severe early onset obesity, hyperphagia and endocrine deficiencies. Exact frequencies of mutation in these genes are not precisely evaluated in french children with severe obesity. Moreover new treatment, such seltmelanotide are avalaible in case of certain mutation, leading to a significative weight loss in treated patients.

The goal of this clinical trial is to test whether an adaptation of an evidence-based, couple-based preventive intervention at the transition to parenthood improves reduces obesity risk among infants and parents in military families via improved interparental support and coordination around health lifestyle behaviors and parenting. The main question it aims to answer is whether an adapted, innovative family-focused approach to obesity prevention can reduce rapid infant weight gain, new mothers' postpartum weight retention, and fathers' weight status. Participants randomized to the Healthy Family Foundations (HFF) intervention condition will participate in 10 online group classes (5 prenatal and 5 postnatal). Participants randomized to the control condition will receive standard of care and opportunities for education at their site. Researchers will compare the Healthy Family Foundations (HFF) intervention group with a Standard of Care control group to see if there are differences in weight, coparenting support, parent mental health and parent health behaviors.

This study is a prospective, multicenter clinical trial. The study is planned to be conducted at a qualified clinical trial center, and 30 subjects are planned to be enrolled to evaluate the feasibility and safety of magnetically controlled capsule endoscopy (MCE) system in the examination of gastric disorders in patients with moderate to severe obesity (BMI ≥ 35 kg/m2).

The aim of the study is to set up and validate a reliable and reproducible automated method using preoperative radiological imaging to measure the TSBL in patients undergoing laparoscopic bariatric/metabolic surgery.

The goal of this clinical trial is to compare de effect of vitamin K2 in young adults with overweight or obesity. The main questions to answer are: What is the effect of Vitamin K2 supplementation on methylation, serum concentration of ucOC, cOC, Gas6, leptin, inflammatory markers, cardiometabolic risk factors, and cardiovascular risk in overweight or obese young adults? Participants will be assigned to one of two intervention groups where they will consume Vitamin K2 100 µg per day or cornstarch 500 mg per day for 90 days. If there is a comparison group: Investigators will compare the supplementation group (Vitamin K2) with the placebo group (cornstarch) to see if vitamin K2 supplementation modifies methylation, increases serum vitamin K, osteocalcin, growth arrest-specific 6 protein serum concentration, decreases serum leptin concentration, inflammatory markers and reduces cardiometabolic risk factors and cardiovascular risk.

Using a two-group randomized study design, this study aims to evaluate the effectiveness of the adapted family-centered mHealth tool on child BMI z-score (primary outcome), child dietary behaviors, and parental feeding practices, from baseline to 12-month follow-up, among 200 child-parent dyads. It is hypothesized that children in the experimental group will demonstrate larger BMI-z score improvements between baseline and 12-month follow-up compared to children in the comparison group.

Endoscopic retrograde cholangio-pancreatography (ERCP) is commonly performed under deep sedation to provide amnesia, comfort, and optimal procedural conditions. However, anesthetic drugs commonly used such as midazolam and/or propofol and opioids for sedative endoscopy in clinical practice may depress normal ventilation by blunting central chemoreceptor responsiveness to CO2, and alveolar hypoventilation and predispose patients to upper airway obstruction; all of that can result in hypoxemia, hypercarbia, respiratory acidosis, hypotension, and, in rare cases, brain injury or death.(1-3)

Approximately one half of adults and one-fifth of children have obesity, including 14% of 2-5-year-olds. Early obesity prevention is essential as children who are overweight by age 5 are at increased risk for later obesity. Dietary intake is inextricably linked to weight status, and the majority of young children fail to meet intake recommendations, with socioeconomically disadvantaged and racial/ethnic minority children at increased risk of poor diet quality. However, children's liking of healthier foods predicts their intake, and children can learn to like healthier foods via experience. The current study brings together evidence from the parenting and learning literatures to: 1) examine effects of a novel learning strategy leveraging positive parent-child interactions on 3-5-year-old children's vegetable acceptance and dietary intake, as well as to explore 2) individual differences in learning strategy effects.

The purpose of the study: To develop a differentiated management strategy for obese children based on the analysis of the relationship between their clinical, metabolic, immunological and microbiological status Research objectives: To give a clinical and metabolic characteristic of a group of obese children (age, gender, degree of obesity, body mass index SDS, the presence of complications of obesity, clinical signs of metabolic syndrome, laboratory markers: AlT, AsT, cholesterol, high and low density lipoproteins, uric acid, insulin, leptin). To study the immunological indicators of inflammation in obese children (the level of highly sensitive CRP, proinflammatory cytokines - IL-1b, IL-6, IL-10, IL-18, TNF-α). To assess the state of the intestinal microbiota in obese children by MALDI-TOF mass spectrometry. To analyze the relationship of clinical-metabolic, immunological and microbiological status in obese children and identify markers associated with metabolic syndrome and the formation of complications. Materials and methods: At stage 1, it is planned to conduct a cohort study in a group of school-age children with obesity (n=120) with the study of their clinical, metabolic, immunological and microbiological status. The control group will consist of healthy children of the appropriate age who are not overweight (n= 20). Stage 2 of the study consists in prospective observation of children of the examined group who do not have complications and clinical manifestations of metabolic syndrome for 6 months against the background of standard therapeutic measures (diet, lifestyle correction, physical activity) and repeated clinical and laboratory examination.

Obesity is a common risk factor for the development of obstructive sleep apnea. However, not all subjects with obesity develop obstructive sleep apnea. This study will attempt to determine the mechanistic drivers between obesity and obstructive sleep apnea.
