Active clinical trials for "Obesity"

You are being asked to take part in this study because either you are a survivor who has a previous history of colorectal cancer or an MD Anderson patient who had a precancerous colorectal polyp or you have a previous history of colorectal cancer, and you have a current adult body mass index (BMI) score of 25 or higher. The BMI score is used as an indicator of the level of body fat, based on height and weight. The goal of this clinical research study is to learn if eating canned, pre-cooked beans can help improve the levels of healthy bacteria in the digestive system and reduce the effects of obesity on cancer risk. This is an investigational study. Up to 80 participants will be enrolled in this study. All will take part at MD Anderson.

With the project proposal we aim to identify serum markers for the characterization of steatosis in subjects affected by essential obesity at a young age. In this case the markers could be useful not only for the development of new diagnostic scores, or for combining them with diagnostic imaging technologies, but also for understanding the metabolic alterations according to the patient's gender, extremely important data in this disease to which only recently has biomedical research started.

Rationale: Weight loss therapies should aim to reduce fat mass while preserving both muscle mass and muscle strength. Consequently, there is a need for validated methods to measure muscle mass and strength. Current methods are either expensive and require trained technicians, or have not been validated in populations with class II/III obesity (BMI > 35 kg/m2). In our previous studies (MUST-MOP and MUSCLE study), we have validated the use of ultrasound (US) for the measurement of lean mass (a proxy for muscle mass) in a population with obesity. These studies showed that the use of US for the measurement of lean mass was feasible, reliable and valid. The aim of the current study is to validate the use of US for the measurement of lean mass after weight loss in a population of bariatric surgery patients. Objective: Primary objective: To assess the validity of US to measure lean mass after weight loss in a population of bariatric surgery patients. Secondary Objectives: To assess de differences in lean mass between DXA and US in this study compared to the MUSCLE-study. To assess how the lean mass has changed after bariatric surgery and the effects of lean mass on total weight loss and resolution of comorbidities To assess whether the change in lean mass has an effect on serum levels of markers for muscle mass. Study design: This study is an observational follow-up study of the MUSCLE study and will take place in the Centre Obesity Northern-Netherlands (CON) at the Medical Centre Leeuwarden (MCL). Study population: The population will consists of participants, who have participated in the MUSCLE study and have received bariatric surgery at the CON / MCL. Main study parameters/endpoints: The main parameters of this study are: lean mass measured by DXA and US. The main endpoint of this study is the validity of the US measurement of lean mass compared to DXA. Nature and extent of the burden and risks associated with participation, benefit and group relatedness: There are no direct benefits for the participants. However, the results of this study can help to further validate the ultrasound as a cheaper and more accessible method to measure muscle mass. This can potentially be used in standard clinical care to assess muscle mass of patients during weight loss. • The additional time investment: during first year follow-up appointment approximately 30 minutes. The risks of most test are minor, even the small amount of radiation exposure, which means the risks and burden of this study outweigh the potentially obtainable knowledge.

Consumption of sweetened beverages, media-viewing, and physical activity patterns are often established during early childhood, and family-based obesity interventions show effectiveness in shaping healthy behaviors and weight outcomes for young children, including Latino children. Missing from these interventions, however, are methods to increase accessibility and dissemination to multiple family caregivers. The proposed work will use a randomized study design to evaluate the impact a family-based early childhood obesity intervention for Latino families that incorporates evidence-based strategies of in-person childhood obesity interventions, mobile phones, and leverages important determinants of Latino health (e.g. familism, language) in order to decrease ethnic disparities in childhood obesity and cardiovascular risk.

General anesthesia and mechanical ventilation decrease pulmonar volume; attenuate small airway closure, atelectasis, and increase the rate of hypoxia and postoperative pulmonary complications. Lung volume in obese patients decreases inversely with the increase in body mass index. Obesity is associated with increased atelectasis, hypoxia and postoperative pulmonary complication rates during anesthesia . Alveolar recruitment maneuver is a technique where high positive end-expiratory pressure (PEEP) is applied for for short periods, follwed by a continuous PEEP appşication throughout surgery. This has become a standard practice during anesthesia in recent years. Oxygen reserve index (ORi) is an index measured with a non-invasive finger-tip sensor and shows the oxygen content of the venous blood. It is effective at high oxygen levels and may indicate the presence of hyperoxia. Our aim is to examine the effect of alveolar recruitment maneuver on oxygenation parameters under anesthesia and the correlation with ORi in morbidly obese patients.

This project aims to move what is currently a specialty-care model for the management of obesity of children and adolescents into the primary care setting.

This study evaluates the relationship between weight loss, circulating inflammatory markers and lipids from 24 patients before and after 6 months of pharmacotherapy as a standard of care for anti-obesity treatment

The present observational cross-sectional study is aimed to assess: the hidden hypercortisolism (HidHyCo) prevalence in a sample of Type 2 diabetes (T2D) patients and the clinical characteristics more frequently associated with the HidHyCo presence and the HidHyCo prevalence in an adequate sample of obese patients without T2D and the clinical characteristics more frequently associated with the HidHyCo presence.

The identification of safe and effective strategies for weight loss and long-term maintenance is critical to reduce the alarming prevalence of obesity worldwide and mitigate obesity-associated health risks. Specifically, Binge Eating (BE) and Food Addiction (FA) behaviors are well known causes of failed weight loss and weight regain. The definitions of their clinical phenotypes are currently evolving. Recent evidence suggests that food choices, behavior and reward may be driven also by taste perception. The hypothesis of this study is that subjects with dysfunctional eating behavior have different taste thresholds compared to obese subjects without eating disorders, and that this characteristic influences food choice and eating behavior. Identifying a difference in the taste thresholds between obese with and without eating disorder will allow us to understand why certain individuals over-consume or binge on densely caloric foods and to give them a tailored dietary treatment so as to maintain weight loss for a long time. The Binge eating and Food Addiction is assessed using Binge Eating Scale and Yale Food Addiction Scale 2.0. Subjects with obesity recruited are divided in 4 groups: without eating disorder, with food addiction (FA), with binge eating (BE) and with FA + BE. In these groups sweet and salty taste will be measured with the 3-Alternative-Forced-Choice method.

It is a randomized parallel arm intervention study in adults with severe obesity. The objective is to demonstrate that within a dietary handling for weight loss, the daily ingestion during 3 months of whole dairy products enriched with milk polar lipids or whole dairy products decreases to a greater extent fasting plasma apolipoprotein B concentrations than the daily ingestion of low-fat dairy products (control group). Metabolic parameters will be assessed before and after the 3-month intervention, both at fasting and in postprandial period after the consumption of standardized meals.
