Filter by:Inflammation in the adipose (fat) tissue is an important condition leading to metabolic derangements and cardiovascular disease in obese patients. n-3 polyunsaturated fatty acids exert anti-inflammatory effects and prevent adipose tissue inflammation in rodent obesity. This study tests the hypothesis that n-3 polyunsaturated fatty acids ameliorate adipose tissue inflammation in morbidly obese patients.
The aim of this study is to assess that the sleeve gastrectomy can improve the risk benefit than the gastric bypass
Levels of tocotrienol in human tissues following supplementation is not currently known. The objective of this present study is to determine the levels of this form of vitamin E in the human tissues such as skin, heart, lung, liver, adipose tissue, Brain and cerebrospinal fluid (CSF) following oral supplementation
Despite progress in understanding the pathophysiology of obesity, current strategies for its medical management remain largely ineffective. Most efforts have focused on reducing caloric intake or increasing energy expenditure, either through behavior modification (e.g. dieting, regular exercise) alone, or augmented by pharmacologic efforts to decrease appetite, inhibit fat absorption, or alter metabolism. Bariatric surgery remains the only proven long term treatment of morbid obesity. Super morbidly obese (SMO: Body Mass Index (BMI) > 50) and super super morbidly obese (SSMO: BMI > 60) patients lose considerable weight, but stabilize at Body Mass Indexes (BMIs) that are still obese or even morbidly obese after risking considerable morbidity and/or mortality. Among commonly performed bariatric surgeries, a laparoscopic two-stage procedure, in which an initial restrictive procedure is followed after a weight loss of ~100 lbs by a more complex procedure that creates malabsorption, is gaining interest. Initial studies have demonstrated very good long-term weight loss with minimal morbidity, and no operative mortality in these high risk patients. Availability of biospecimens obtained at each stage of this protocol will allow participating scientists a unique opportunity to test in human tissues hypotheses developed in animals. Studies proposed under this application focus on fatty acids and overall fat disposition in fat depots (adipose tissue) of your body, and the role of adipose tissue hormones and inflammatory processes in obesity and its associated health related issues.
The aim of this study is to assess whether the energy you burn daily increases after you have bariatric surgery. Until now, there hasn't been an effective way of measuring all activity on a daily basis. Physical Activity Monitoring System (PAMS) has been created just for this purpose. PAMS is a garment that can be worn under your clothes, that records body position and movement through space. We will use the PAMS along with special water to measure your total daily energy expenditure right before surgery, and again 6 months and 24 months after surgery. Study subjects will be initially recruited from OHSU IRB-Approved advertisements. Interested study subjects will be screened through an informal telephone interview. If there are no health conditions that exclude participation, subjects will be asked to give IRB-approved consent. Subjects will be consenting to undergo three 18 day phases. Each phase will consist of 15 daily visits to the Clinical & Translational Research Center (CTRC), and 3 full day and nights in the CTRC.
Morbid obesity currently affects more than 11 million US adults and is strongly associated with type 2 diabetes, cancer, cardiovascular disease, and arthritis. Bariatric (weight loss) surgical procedures have been shown to significantly reduce body weight and improve the health and quality of life of morbidly obese adults, at least in the short term. However, bariatric surgery also presents substantial risks, including a 10% to 20% risk of serious complications and up to a 2% risk of death in the first 30 days after surgery. Thus, a morbidly obese patient's decision regarding bariatric surgery should be based on his or her evaluation of accurate information on the possible risks and benefits of the various treatment options. Anecdotal reports suggest that bariatric treatment decisions may be more heavily influenced by insurance coverage and reimbursement rates than patient preferences. The main objective of the current proposal is to examine the impact of a bariatric decision aid, Weight loss surgery: Is it right for you?, on decision quality in primary care and bariatric specialty practice settings. We propose a randomized controlled trial to assess the effect of this bariatric decision aid on bariatric-specific measures of patient knowledge, values and choice of weight management strategy. We will also investigate the effect of the decision aid on decisional conflict and decisional self-efficacy and examine medical, psychological, and behavioral factors as mediators and moderators of treatment choice. This information will help to elucidate the value of this decision aid in improving decision quality. The primary aims of this of this research are to: 1. Determine if the bariatric decision aid results in superior bariatric surgery decision quality than an NIH booklet on weight loss surgery ('usual care'). 2. Determine if the bariatric decision aid results in less decisional conflict and superior decisional self-efficacy than usual care. 3. Determine if there is a differential effect of the interventions on decision quality among treatment seekers and non-treatment seekers. 4. Investigate medical, psychological, and behavioral factors as mediators of treatment choice. The secondary aims of this study are to: 1. Understand the current weight control attitudes and practices among morbidly obese patients who are not actively seeking bariatric surgical treatment. 2. Assess the rates of bariatric surgery, health care costs, health care use and outcomes, and changes in BMI over time across the intervention groups, as well as across study subgroups, such as those who did and did not choose to have bariatric surgery. We hypothesize that the decision aid will result in greater knowledge and greater values concordance, less decisional conflict and superior decisional self-efficacy than the NIH booklet.
The purpose of this study is to investigate the relationship between the potential predictive psychological variables and success after bariatric surgery. The investigators will also investigate the purpose of a pre- and postoperative psychological intervention.
The purpose of this study is to determine the natural course of the androgen profile after bariatric surgery in men with obesity related hypogonadotropic hypogonadism.
The purpose of the trial is to determine whether a preoperative lifestyle intervention (targeting diet, exercise, and preparation for surgery) will favorably impact obesity-related parameters prior to bariatric surgery and improve short-term postoperative outcomes.
The primary aim of our study is to test the hypothesis that wound healing is impaired in the patient who has experienced massive weight reduction following gastric bypass for morbid obesity. Specifically we will document post-surgical local complications and evaluate multiple wound healing parameters in two patient populations in a prospective fashion. The test group will consist of patients who have undergone dramatic weight loss and are much in need of a panniculectomy due to excessive skin redundancy. The control group will consist of patients within normal weight ranges who are seeking an abdominoplasty.
