Filter by:This is a pilot study to determine the safety and efficacy of an investigational product (IHBG-10) on weight change and changes in body composition in subjects who have been taking a stable dose of certain anti-psychotic medications for longer than three months.
This is a pilot study to determine the safety and efficacy of an investigational product (IHBG-10) on weight change and changes in body composition in subjects who have just started taking (for less than three months) certain anti-psychotic medications (Risperdal, Seroquel, and/or Zyprexa).
Scientists have discovered a number of hormones that control our feelings of hunger and fullness. One particular hormone, called GLP-1, has been associated with feelings of hunger and fullness. The overall purpose of this study is to look more closely at how GLP-1 changes these feelings and to observe how these hormones affect the brain's function. To do this, volunteers will be asked to come to the clinic for a screening visit, and 2 study visits. This is an outpatient study with a screening visit which will last about an hour and the two subsequent study visits for about 3 hours each. During the study, patients will receive a drug that blocks the effect of a hormone made in the gut. We will take a series of blood samples to measure hormones and use functional magnetic resonance imaging (MRI) to take pictures of the brain. Understanding the action of these hormones in the brain may eventually lead to new ways to help people avoid obesity or lose weight.
The purpose of this study is to evaluate the effect that weight loss has on the severity of psoriasis in obese subjects. Fifty obese (BMI equal to or greater than 30) patients with moderate to severe plaque psoriasis will be enrolled in a weight loss intervention program. The severity of their psoriasis will be reevaluated at month 3 and month 6 of the program to determine what effect weight loss has had on their psoriasis. Serum TNF-alpha will be measured at month 0 and month 6. The hypothesis that will be tested is that weight loss will lead to a significant improvement in the severity of psoriasis and a reduction in TNF-alpha levels.
The purpose of this study is to determine whether two new airway devices used during anesthesia called iGEL™ and KING-LTS-DTM work well and are safe in obese patients. They both work well in thin patients, but have not been tested in obese patients.
This is a feasibility study to examine the treatment with Metformin, vitamin D with calcium supplement for insulin resistance in obese, black, female teens. The association of low vitamin D levels and decreased insulin sensitivity has been established. Thus, the specific aims of this study are: Specific aim 1: To examine the effect of an 8-week treatment with vitamin D and calcium supplementations on diabetes-related risk factors in obese, black, female teens. Hypothesis 1a: In obese, black, female teens with both insulin resistance and vitamin D deficiency, treatment with vitamin D and calcium supplementation will significantly improve measures of insulin resistance and sensitivity (as determined by the homeostatic model assessment for insulin resistance and whole body insulin sensitivity index measures) when compared to controls not receiving vitamin D and calcium. Hypothesis 1b: In obese, black teen females with both insulin resistance and vitamin D deficiency, treatment with vitamin D and calcium supplementation will significantly improve measures of cardiovascular disease (decreased BMI and improved triglycerides and LDL) when compared to controls not receiving vitamin D and calcium. Specific aim 2: To determine if the addition of Metformin to the 8-week treatment with vitamin D and calcium supplementations improves diabetes-related risk factors in obese, black, female teens. Hypothesis 2a: In obese, black, female teens with both insulin resistance and vitamin D deficiency, treatment with Metformin, vitamin D, and calcium supplementation will significantly improve measures of insulin resistance and sensitivity (as determined by the homeostatic model assessment for insulin resistance and whole body insulin sensitivity index measures) when compared to standard of care or treatment with vitamin D with calcium supplementation alone while controlling for dietary intake of vitamin D and calcium. Hypothesis 2b: In obese, black, female teens with both insulin resistance and vitamin D deficiency, treatment with Metformin, vitamin D, and calcium supplementation will significantly improve measures of cardiovascular disease risk (as determined by the decreased BMI, improved triglycerides and LDL) when compared to standard of care or treatment with vitamin D with calcium supplementation alone while controlling for dietary intake of vitamin D and calcium.
The purpose of this study is to investigate the evolution of daytime partial pressure of carbon dioxide in the blood (PaCO2) after 6 weeks of noninvasive ventilation-pressure support ventilation (NIV-PSV) with target volume versus continuous positive airway pressure (CPAP) alone versus NIV-PSV.
The purpose of this study is to determine laparoscopic sleeve gastrectomy is a safer surgery than the gastric bypass, gives similar weight losses and that the safety of gastric in private pay patients versus insurance patients will be similar. This is a retrospective chart review of intervention charts.
The Pediatric Obesity Research Registry will function to collect and catalog historical and medical chart related clinical data of patients presenting with pediatric obesity and who agree to participate.
Participants will be employees of Genzyme who volunteer to participate in a study on motivating healthy behaviors, involving giving them goals for taking a certain number of steps per day, and increasing that number over time. Participants will wear pedometers and upload their data to a website that allows them to monitor their progress, and have the opportunity to win money based on meeting their step goals. Interested employees will schedule a day and time to complete a health screening at a "Health Fair" at their place of employment, to ensure that they are healthy enough to participate; at this time participants will also complete the investigators baseline dependent measures, and receive a pedometer. After a one-week baseline period during which they wear the pedometer and the investigators establish their typical number of steps per day, eligible participants will then be assigned to one of four treatments - a "no incentive" control condition, and three conditions in which they are entered into different kinds of monetary lotteries if they have met their step goals for that day. Participants' initial goal will be based on their steps during the baseline period, and the goal will increase by 250 steps each week, for a total of 12 weeks. After these 3 months, the incentives portion of the experiment ends, but participants continue to wear their pedometers and upload their data for an additional 6 months. At 3 months, 6 months, and then at the study end at 9 months, participants again complete the investigators dependent measures at follow-up Health Fairs at their place of employment.
