Filter by:The investigators will recruit obese subjects with pre-diabetes or type 2 diabetes for the proposed clinical study for 5 visits. After informed written consent is obtained, subjects will be admitted to the Clinical Research Center, and will undergo upper endoscopic injection of Botox into the duodenal wall. The investigators anticipate that injections of Botox into the duodenal wall will result in significant weight loss and improvements in glucose tolerance and duodenal nutrient sensitivity. Subjects will be studied over a period of 6 months. Subjects will be asked to complete 5 study visits: On the first visit, each subject will undergo an oral glucose tolerance test. At visit 2, subjects will undergo an esophagogastroduodenoscopy procedure for the delivery of Botox to the duodenal wall. Visits 3-5 will be made 1, 3, and 6 months later. On every study visit, body weight and body composition will be recorded and oral glucose tolerance test will be performed. Nutrient sensing test will be performed at visits 1 and 3.
OBJECTIVES: To investigate whether respiratory variations of the inferior vena cava (ΔIVC) and internal jugular vein (ΔIJV) diameters during standardized breathing (ΔIVCST and ΔIJVST) increase after a therapeutic bleeding in spontaneously breathing and obese patients with dysmetabolic hyperferricemia. DESIGN: Prospective, monocentric study in the EFS Nord-de-France blood center. PATIENTS: Obese patients with dysmetabolic hyperferricemia undergoing a therapeutic bleeding. INTERVENTIONS: The investigators performed ultrasound measures and collected clinical parameters before and after a therapeutic bleeding, during a standardized respiratory maneuver. MAIN OUTCOME AND MEASURES: The primary endpoint was the ΔIVCST change induced by a 300 to 500ml therapeutic bleeding. The investigators measured the minimal and maximal IVC and IJV diameters during a standardized respiratory maneuver. ΔIVCST and ΔIJVST were calculated as follows: [(maximal diameter - minimal diameter)/maximal diameter].100.
Incisional negative pressure therapy (INPWT) has previously been shown in certain patient populations to decrease wound healing complications, decrease the rate of hematomas and seromas, as well as have better scar quality. We have found a group of patients, those who have panniculectomies in preparation for renal transplant, with significantly higher rates of wound healing complications. We believe the best way to demonstrate benefits of incisional negative pressure wound therapy will be in this group of patients known to have significantly higher rates of wound complications.
80% of endometrial cancer patients are overweight or obese. Preclinical and clinical data have shown that caloric restriction (CR) protects against organ injury and decreases perioperative morbidity. This is a feasibility trial to evaluate the effect of a 6 week perioperative CR on surgical and patient-reported outcomes in 20 obese newly diagnosed endometrial cancer patients. The intervention will provide individualized CR program, meal replacement products and nutritional counselling sessions.
Prediabetes, characterized by elevated fasting blood sugar or exaggerated blood sugar response to sugar ingestion, effects over 79 million adult Americans and is a precursor to the development of Type 2 diabetes. Importantly, approximately 42% of Iowans (950,000) have diabetes and 32% (670,000) have prediabetes with the majority of those with prediabetes going undiagnosed. Adults with prediabetes demonstrate early signs of cardiovascular and nervous system abnormalities and are at high risk for developing overt diabetes unless aggressive lifestyle (weight loss, exercise) or pharmacological interventions are employed. Interestingly, data in recent years has linked obesity and diabetes to chronic inflammation of the blood vessels and brain areas that regulate blood pressure. Therefore, the current study will test whether a commonly used aspirin-like anti-inflammatory drug called salsalate, will improve blood vessel health and nervous system dysfunction in adults with prediabetes. Eligible subjects will have measurements of blood pressure, blood vessel function in the arms and eyes, assessments of nerve activity, and blood samples taken before and after 4 weeks of ingesting an FDA approved aspirin-like drug called salsalate. The study is important because it will identify a potentially new pharmacological strategy to treat vascular and nervous system abnormalities in overweight and obese adults with early stage type 2 diabetes using an inexpensive, generically available drug with an excellent safety record that has been used for decades to treat chronic inflammatory conditions such as rheumatoid arthritis. If proven effective, this will provide preliminary support for the concept of targeting inflammation as a new clinical approach to treating early diabetes related complications. Furthermore, the current pilot study will provide support for developing a larger clinical trial using salsalate that could potentially then be extended to patients with type 2 diabetes and cardiovascular disease, as well as lead to the development of new anti-inflammatory agents with greater specificity for selective inflammatory pathways.
Overweight and obesity has been associated with a number of adverse pregnancy outcomes in women of reproductive age, including infertility and early pregnancy loss. Recent data suggests that overweight and obese patients are also at increased risk of recurrent pregnancy loss (RPL), a devastating condition that affects 1% of the fertile population. The investigators propose a prospective, randomized controlled trial in which overweight and obese patients with unexplained recurrent pregnancy loss are enrolled in a structured, 6 month, weight loss program or provided routine counseling regarding the importance of weight loss. Pregnancy outcomes will then be followed to assess miscarriage rates. Metabolic outcomes, such as lipid and glucose profiles, will also be evaluated.
