Bariatric Surgery for morbid obesity is indicated when BMI \> 40 kg/m2 without comorbidities or BMI \> 35 kg/m2 with co-morbidities. Different surgeries performed for obesity are classified as restrictive, malabsorptive, and hybrid procedures. Because laparoscopic surgery has increased the interest and growth of bariatric surgery, soaring demand for laparoscopic bariatric surgery from patients has boosted the boom in bariatric surgery worldwide. Achieving pneumoperitoneum is the initial and one of the most crucial steps in any laparoscopic surgery, giving the surgeon working space to operate on a particular organ/organ system. Usually, pneumoperitoneum is achieved either by a closed technique with a veress needle or an open technique with many variations like finger assisted or the conventional open technique. Given the excess amount of subcutaneous fat in morbidly obese patients, putting a veress needle to achieve pneumoperitoneum successfully is particularly challenging which takes a toll on the operating surgeon when he/she is trying to locate the midline one can either overshoot to cause omental emphysema or undershoot getting lost in the subcutaneous fat. It is usually done in the supra umbilical area. Sometimes, due to previous surgical scars other sites are preferred. Sonography is routinely used by radiologists with negligible radiation exposure. Anesthesiologists in the operating room have used it for many assisted procedures like central line insertion / giving nerve blocks. It can also be used in obese patients undergoing metabolic surgery to assist in creating pneumoperitoneum by a veress needle. Advantages of Intraoperative ultrasonography in this particular study : 1. To quantify the thickness of subcutaneous fat 2. To visualise the linea alba and guide the veress needle safely into the peritoneal cavity 3. Real-time visualisation of the pneumoperitoneum created 4. Avoid complications like omental emphysema, bowel or vascular injury
NCT04095117
The aim of this study is to evaluate the use of the sagittal abdominal diameter (SAD) as a potential predictor of the skin to epidural space distance (SESD) and to compare its accuracy versus that of the BMI as a previously validated predictor

Quasi-experimental, multicentre, before and after. Primary care, hospital units and nursing homes, and the patients attended at both. Implementation of evidence-based recommendations by application of a multifaceted implementation strategy (training, audit, context analysis, local strategies design, feedback, facilitation). Data will be collected at baseline and, during the first year of follow up, at months (4,8,12)
NCT00960414
The purpose of this study is to compare two approaches to a diet and exercise-based weight loss program.
NCT05328791
Meditation interventions, including mindfulness-based approaches, can be effective in reducing psychological stress . Mindfulness meditation, which cultivates awareness of present-moment experience with a nonjudging attitude, is theorized to promote adaptive self-regulation,which is thought to be key to maintaining long-term eating habits and appetite regulation.In the light of this information, in this study, it is aimed to observe the effect of mindfulness approach on body weight and eating behaviours.
NCT06186622
The main purpose of this study is to determine effect of orforglipron capsule formulation on the amount of digoxin, rosuvastatin, acetaminophen, midazolam, and simvastatin (each given alone and together with orforglipron) that enters the bloodstream and how long it takes the body to eliminate them when administered orally in healthy overweight and obese participants. In addition, the effect of the orforglipron tablet on the amount of simvastatin that enters the bloodstream and how long it takes the body to eliminate it will be evaluated. The study will also assess the effect of sodium bicarbonate when administered alone with simvastatin versus orforglipron capsule containing sodium bicarbonate administered with simvastatin. The safety and tolerability of orforglipron and information about any side effects experienced will be collected. Study will be conducted in two parts, with part 1 and 2 lasting up to approximately 23 and 24 weeks each, including the screening period.
NCT06508242
Obesity has emerged as a risk factor in the onset of bone, muscle and adipose tissue impairments that are further aggravated by vitamin D deficiency. A link of an active bone-muscle-adipose axis is represented by Wnt pathway. This study will test the hypothesis that vitamin D improves bone, muscle, and adipose tissue health through a positive modulation of Wnt pathway. It will be carried out a double-blind, placebo-controlled study of cholecalciferol supplementation in vitamin D-deficient obese adults. Specific aims will be: 1) to test the direct effect of vitamin D on Wnt signaling in bone, muscle, and adipose tissue; 2) to evaluate muscle mass and strength; 3) to assess changes in vitamin D status across different administration strategy (weekly, fortnightly, monthly). This study will provide not only insight of new mechanisms involved in the pathophysiology of obesity-related musculoskeletal impairments but also evidence for new treatment recommendations for vitamin D deficiency in obesity.
NCT06506175
The study is being conducted to evaluate the effects of different dosage regimen on the pharmacokinetics of HRS9531 tablets in healthy subjects.
NCT06457711
Obesity is a significant health issue that increases the risk of serious cardiovascular problems. In recent years, two dietary methods, the Ketogenic Diet (KD) and Intermittent Fasting (IF), have become popular for their potential to treat obesity and its related issue, hypertension. While both diets are known for their effectiveness in weight loss, their specific impacts on blood pressure (BP) and overall heart health risks are less understood especially in menopausal women. The main goal of this study was to investigate how the Ketogenic Diet and Intermittent Fasting compare to a regular, unrestricted diet (referred to as Free Diet or FD) in terms of their effects on clinic blood pressure levels in menopausal women. Additionally, the study looked at changes in Body Mass Index (BMI), the percentage of total body weight loss, body fat percentage, waist and hip measurements, the ratio of waist-to-hip size, and the Phase Angle (PhA), which is a measure of the body's overall health status.

Evaluation of PREPL activity in healthy controls and known or possible PREPL deficient patients
NCT06486961
For several decades, scientists have reported encouraging effects of physical activity on functional capacities and quality of life among patients with obesity. However, regular daily physical activity remains limited in these individuals. People with obesity generally show lower adherence to physical activity, with 40% not meeting the recommendations of 2.5 to 3 hours of moderate physical activity per week set by the French National Authority for Health to be considered physically active. Since physical activity is the primary energy expenditure that can be targeted, the priority is to make it appealing through exercise programs tailored to individual needs, abilities, and preferences. To achieve this, using music to facilitate walking appears relevant. Studies show that individuals adhere to physical activity and incorporate it into their routines only if they find it enjoyable. Walking to music is more motivating and enjoyable. Moreover, the rhythm of music enhances the functioning of biological systems involved in walking. Tailored physical activity is a major preventive lever to implement for individuals with obesity. It is essential during the initial weight loss phase and during weight maintenance. The overall objective of this study is to propose a digital tool capable of modifying the behavior of individuals with obesity to reduce sedentary behavior in their daily lives. Synchronized walking to the rhythm of music should help train obese patients towards a virtuous cycle leading to slowed weight gain, reduced associated health problems, and improvements in mental health and quality of life.
NCT03177148
In this cluster randomized effectiveness trial, pediatric primary care practices will be recruited from the American Academy of Pediatrics' national Pediatric Research in Office Settings (PROS) practice-based research network, as well as the client database of the Physician's Computer Company (PCC) - an Electronic Health Record (EHR) vendor. We will recruit 18 practices. 9 practices will be randomized to the Intervention arm and 9 practices to Usual Care. Intervention arm practices will select 1-2 pediatric clinicians, including pediatricians (PED) and nurse practitioners (NP), to receive in-person training in Motivational Interviewing (MI), behavioral therapy, billing and coding, and study procedures. Usual Care practices will select 1-2 pediatric clinicians to receive billing / coding and study protocol training only, via telephone and webinar; they will be offered in-person MI training at the close of the trial. Around 316 parents of overweight or obese children (BMI \> 85th percentile for age and gender) between 3 and 11 years of age at baseline that are patients of participating Intervention arm clinicians will be enrolled. Over 24 months, these parents may receive up to 4 in-person, MI-based counseling sessions with a trained pediatric clinician and up to 6 telephone counseling sessions with an MI-trained Registered Dietician (RD). There will be no study-specific contact with parents or their children in Usual Care practices during the trial - they will continue to receive usual care. EHR and billing data for all 3-11 year old children within all participating practices will be extracted by PCC to permit determination of the effectiveness of the intervention versus usual care on change in BMI z-score among 3 groups: 1) all eligible children in the Intervention arm), 2) all eligible children whose parent actively participates in the trial , and 3) all 3-11 year old children in all participating practices.
NCT06500299
It is a multicenter, randomized, double-blind, placebo-controlled phase II clinical trial to evaluate the safety and efficacy of HDM1002 tablets in overweight and obese adults.
NCT06501326
STUDY OBJECTIVE: To explore the clinical efficacy and safety of liraglutide in obesity combined with metabolism-associated fatty liver disease (MAFLD). INTERVENTION PROGRAM: All subjects underwent dietary control and exercise therapy, and controlled smoking and alcohol consumption. During the 3 months of the trial, men were instructed to follow a diet of 1,500 to 1,800 kcal per day and women followed a diet of 1,200 to 1,500 kcal per day. All three diets included 40 to 55 percent carbohydrates, 15 to 20 percent protein and 20 to 30 percent fat. During the 3-month trial period, subjects performed at least 150 minutes of moderate-intensity exercise per week with an energy expenditure of 1500 kcal/week or more. Other medications containing the same ingredients as orlistat and liraglutide were prohibited during the trial period. After randomization, the control group was treated with lifestyle intervention + orlistat until the end of follow-up. Trial group 1 was treated with lifestyle intervention + liraglutide. Trial group 2 was treated with lifestyle intervention + liraglutide + orlistat for a total treatment and follow-up period of 3 months.
NCT06499597
Today, obesity is a global health problem and can lead to serious health complications. Bariatric surgery is recognized as an effective treatment option to achieve long-term weight loss and health improvement in overweight or obese individuals. However, appropriate tools are needed to assess the physical activity levels of patients before and after bariatric surgery and to guide rehabilitation processes after surgery. The Duke Activity Index (DAI) is a scale used to assess activities of daily living and was developed at Duke University Medical Center. The DAI has been widely used to determine patients' physical functioning and monitor their activity levels in various health conditions and post-surgical recovery processes. The aim of this study was to evaluate the psychometric properties of the DAI and to examine whether it is an effective tool for determining physical activity levels in patients who are candidates for bariatric surgery.
NCT06263621
The goal of this this intervention is to test the degree to which a portion size labeling intervention influences consumer selection of smaller portions at two large cafés. The main question it aims to answer is: Do consumers order fewer calories when the portion size label for the smaller entree is called "standard" instead of "small"? Participants will order lunch as usual in the two cafes (one intervention, one control) for 5.5 months, and all order items will be recorded in the check-out system. One cafe will receive the labeling intervention, while the other will not. Researchers will compare the average calories per order between the two cafes to see if there are differences.
NCT06494566
The study evaluates diet supplementation of Omega-3 fatty acids after surgical treatment of obesity in adults. Half participants will receive diet supplementation of Omega-3 fatty acids, while the other half will receive placebo.
NCT04847271
Background: physical inactivity is a main cause of childhood obesity. Physical activity on prescription (PAP) is an evidence-based intervention for adults, but has not been evaluated in children with obesity. Aim: to evaluate the feasibility of a PAP intervention for children with obesity by assessing both clinical patient outcomes and implementation outcomes. Method: a single-arm clinical trial in which children with obesity participate in a 4-month PAP intervention. Measurement points are baseline and 4 months, with long-term follow-ups at 8 and 12 months. Population: children with obesity. Intervention: physical activity on prescription (PAP). Patient outcomes: physical activity level/pattern (including sedentary time), BMI, waist circumference, metabolic risk markers, health-related quality of life, self-efficacy for physical activity, motivation for physical activity. Implementation outcomes: coherence, cognitive participation, collective action, and reflexive monitoring in relation to PAP (the four core constructs of the Normalization Process Theory); appropriateness, acceptability and feasibility of PAP; barriers and facilitators for implementing PAP; recruitment and attrition rates, and intervention fidelity and adherence.
