Active clinical trials for "Obesity"

The main objective is to investigate chronobiological aspects of childhood obesity studying the potential relationship between meal patterns and circadian rhythmicity in a cross-sectional sample of obese, overweight and normal weight children/adolescent.

Today sleeve gastrectomy is the most performed bariatric procedure worldwide. Since 2005 it is gaining popularity as a single procedure. Long term data is scarce. In this retrospective study long term follow-up in relation to weight loss, comorbidities, re-do and revisional surgery is getting analyzed.

A prospective observation study to screen adult obese (BMI ≥30 kg/m2) patients who were newly admitted to the medical intensive care units and turned out to be diagnosed as Obesity hypoventilation syndrome(OHS). The investigators purpose is to look into the prevalence, predictive factors, and outcomes of OHS in these critically ill patients.

Pseudohypoparathyroidism type 1a (PHP1a) is a rare disease that causes childhood obesity and learning difficulties. This study will investigate eating behaviors and perform cognitive testing on children with PHP1a. The investigators will compare their results to those of healthy siblings and other obese children.

The hypothesis of this study was that gastric bypass (GBP) ameliorates gastroesophageal reflux disease (GERD) in morbidly obese patients.

Objective: to assess the health and economic outcomes (weight lost, change in control of chronic diseases such as diabetes, quality of life, work productivity, health care cost, etc) associated with bariatric (weight-loss) surgery for 200 severely obese patients who undergo bariatric surgery as part of the Mississippi State Employees' Life and Health Insurance Plan's Obesity Treatment Program (OTP). 2. Patient Characteristics: Inclusion criteria: Eligible bariatric surgical candidates who are enrolled in the OTP (100 patients per year for 2 years). The Plan's criteria includes, but is not limited to 1) enrollment in the plan for at least 12 consecutive months prior to September 1, 2009; 2) completion of the HealthQuotient health risk assessment through the Plan's wellness and health promotion program; 3) a Body Mass Index (BMI) of >40 kg/m2, or a BMI >35 kg/m2 with two or more co-morbidities such as diabetes, hypertension, sleep apnea or asthma; 4) two or more physician-supervised weight loss attempts within the last 24 months; 5) age 18 years or older; and 6) consent to provide personal and medical information to the Plan. Prior to surgery, each site administers a psychiatric evaluation to ensure the patient is psychologically stable for surgery. Exclusion criteria: any patient who does not meet criteria above or who declines to participate. Surgeries will take place only at Certified Bariatric Surgery Centers of Excellence (COE), of which, there are currently 3 in the state. The 3 COEs exist with 4 outpatient medical offices (1 COE is composed of 2 independent surgeon practices) Patients will be recruited at each site once they are approved by the OTP. 3. Design: prospective, observational, multi-center, longitudinal study of outcomes and resource utilization associated with OTP. Estimates of obesity and comorbidities' impact will be obtained from the outpatient medical office for the COEs. Medical charts, databases and medical/pharmacy claims will be the source of information. Surveys on quality of life, productivity, and patient satisfaction will be administered directly to patients. Database claim information will be obtained in future and is not a part of current IRB application. 4: Procedures: After obtaining informed consent, patients will be administered surveys at baseline, as well as at follow-up visits. Additional data will be obtained via patient charts, databases, and medical/pharmacy claims.

The purpose of this study is to determine whether verification of correct tube placement after endotracheal intubation in the obese patient can be conducted as fast with ultrasound as with the conventional method of combined auscultation and capnography. The investigators hypothesize that ultrasound is a faster method for verifying correct endotracheal tube placement in the obese patient than combined auscultation and capnography.

Although instruments such as pedometers and heart rate monitors are helpful for those who use exercise to maintain their weight, they do not actually measure calories expended, which is a critical piece of information necessary for sustained weight management. The purpose of this study is to determine the accuracy of a new device that measures calories burned based upon heat produced by the body. Since heat production is directly proportional to calories burned, this device has the potential to accurately measure energy expended in many different settings.

The problem point of the Prader-Willi Syndrome (PWS) patient is the obesity which is intense and the plasma ghrelin level which increases unusual from the recently PWS patients was discovered. The Ghrelin is endogeneous ligand of growth hormone secretagogue receptor with peptide hormone and the location is 3p26-p25. Becomes the secretion even from nervous system but from dignity X/A cell it is secreted mainly and growth is important even in the vagal control against food and intake and a dignity function even on the action outside which promotes the secretion which drives it operates. It increases food intake specially and in order to accomplish the action which diminishes fat utilization the obesity with the week cause which it does the mortar it is thought. Active the ghrelin of the form is essential in hormonal activity of the ghrelin and appetite and growth hormone it participates to the secretion promotion which drives. Action of the Ghrelin measuring the quantitative change in middle acylated of the PWS patient ghrelin in order to happen after the acylation initially by one interest ghrelin which is attempted the appetite of the PWS patient is is controlled the method it will be able to prove the thing directly, it used the RIA kit and the ELISA it will be able to measure kit it will be able to measure the whole ghrelin to pick the PWS patient and the blood of the normal army and active ghrelin it measured a change.

This study will assess various published staging tools to assess the health impacts of obesity on individuals. The aim is to identify benefits and drawbacks, and thus help Obesity Centres and GPs better assess obese individuals as well as better identify who benefits most from having weight loss treatment.
