Active clinical trials for "Obesity"

The Canadian pediatric obesity epidemic has led to great interest in evaluating weight management care for obese children and families. Investigation is warranted since obesity is linked to risk factors for chronic diseases including type 2 diabetes mellitus (T2DM) and cardiovascular disease (CVD). Over the past 25 years, many interventions have studied the role of healthy lifestyle behaviours to help obese children achieve and maintain a healthy weight. A contemporary view of pediatric weight management interventions includes parents as a fundamental recipient of treatment. These interventions recognize the influence parents have on the lifestyle behaviours of their children. While such parent-based interventions have helped establish the role of education and behavioural theory in facilitating lifestyle changes, we believe an equally important intervention element is a focus on the role of cognitions in helping to interpret behaviour change and change maintenance. Our study incorporates cognitive behaviour theory (CBT) into an intervention for parents of obese children and compares it to a more traditional modality based on psycho-education (PEP). Hypothesis: Obese 8 - 12 year old children (n=45) whose parents complete a 16-session, group-based, CBT intervention will achieve greater reductions in adiposity as well as improvements in physiological risk factors for T2D, lifestyle behaviours, and psychosocial outcomes at post-intervention as well as 6- and 12-months follow-up versus children (n=45) whose parents complete a 16-session, group-based, psycho-education intervention . Primary Objective: To compare the impact of two weight management interventions (CBT versus PEP) for parents of obese children on child BMI z-score. Secondary Objective: To measure a comprehensive set of physiological, behavioural and psychosocial outcomes in obese children and parents pre- and post-intervention. We expect obese children whose parents complete the CBT intervention will experience greater reductions in BMI z-score vs. children whose parents complete the PEP intervention. We anticipate that improvements in parenting style, family stress, and lifestyle behaviours will be important to improve adiposity, lifestyle behaviours, and risk factors for T2DM and CVD in obese children.

This is a randomized clinical trial assessing the outcome of two surgical strategies to treat severe obesity; laparoscopic gastric bypass and laparoscopic VBG. Main outcome is weight loss and weight loss maintenance but other factors as body composition, eating pattern, metabolic normalisation, energy expenditure will also be assessed.

Stanford GOALS is a large-scale, community-based randomized controlled trial of an innovative, interdisciplinary, multi-component, multi-level, multi-setting (MMM) approach to treating overweight and obese children. Primary Research Question: Will a 3-year, innovative, interdisciplinary, multi-component, multi-level, multi-setting (MMM) community-based intervention to treat overweight and obese children significantly reduce BMI compared to an enhanced standard care/health and nutrition education active comparison intervention?

Eighteen patients were given a dose of 2g Cefazolin in anesthetic induction, supplemented with 1g delivered through continuous infusion during surgery. Adipose samples, obtained at the beginning and end of surgery, were analyzed using high performance liquid chromatography. Some published studies suggest that the dose of 2g does not supply the minimum inhibitory concentration for principal causal agents of surgical site infection. To determine the concentration of Cefazolin in adipose tissue of patients undergoing bariatric surgery and to evaluate the relationship between concentrations obtained and body mass index (BMI).

Aim 1 - The primary aim of the study is to assess whether group counseling is a non-inferior intervention compared to the usual care of individual counseling in the management of childhood obesity. In order to achieve this aim, the investigators will compare the mean change in BMI after 6 months of intervention in the two study arms. Aim 2 - The secondary aim of the study is to determine if the change in BMI is associated with changes in the dietary composition, physical activity and metabolic profile.

During laparoscopic bariatric surgery, adequate muscle relaxation is important to maintain good surgical conditions. To achieve this muscle relaxation, neuromuscular transmission blocking agents, such as rocuronium (Esmeron®) are used. It sometimes happens that there is still some neuromuscular blocking activity left in the patient on awakening from anesthesia. This is called residual curarization and is known to cause postoperative complications such as impairment of respiratory function. Sugammadex (Bridion®) is a novel drug which selectively binds rocuronium (Esmeron®). It allows for reversing of neuromuscular transmission blocking activity. Until now, all studies with sugammadex were performed in non-obese patients. Obese patient have a high risk to suffer from post-operative respiratory failure. Therefore it is vital to avoid residual curarization. Sugammadex might be an important factor. Obese patients have a large total body weight different from ideal body weight. Recent research demonstrated that the dose for the neuromuscular blocking agent rocuronium (Esmeron®) needs to be calculated on the patients' Ideal Body Weight rather than on Total Body Weight. At this moment no data is available on the dose-response relationship of sugammadex in morbidly obese patients. We hypothesize that in morbidly obese patients sugammadex should be dosed on ideal bodyweight, instead of total bodyweight.

The purpose of this study is to compare the 6- and 12-month weight changes associated with lifestyle interventions delivered in a large group or small groups of participants. It is hypothesized that participants receiving treatment in a small group will have greater weight loss than those assigned to a larger group.

The purpose of this study is to determine whether exenatide can cause weight loss in patients with a history of craniopharyngioma or other brain lesion.

The purpose of this study is to determine the utility of an hypocaloric diet with or without bread in patients with overweight and obesity

Obesity is a heightened state of inflammation in which production of cytokines and matrix metalloproteinases (MMPs) result in loss of function of insulin receptors and insulin resistance. Doxycycline (DOX) is a potent MMP inhibitor. We hypothesize that DOX will enhance insulin sensitivity and decreases inflammation in obese participants with type 2 diabetes (DM2).
