Filter by:This is a prospective, randomized clinical trial for patients with recurrent type 2 diabetes post-gastric bypass surgery that will compare a 6 month course of canagliflozin monotherapy vs. placebo on clinical outcomes of type 2 diabetes.
New studies are revealing how a high-fat diet could be making the cells of the intestinal lining more likely to become cancerous. The investigators would like to study how obesity influences growth of intestinal stem cells, which could then trigger intestinal tumors. The investigators are proposing a Pilot Study of 20 subjects (comprised of 10 participants from each of two different BMI categories: 20-25 and 35 & above), who will be asked to provide blood, stool, & urine samples, undergo a flexible sigmoidoscopy, and complete food frequency questionnaires
The growing population of obese adults is predicted to create a large public health burden in the next few decades. This study examines function of small blood vessels providing blood flow to skeletal muscles, to test if younger obese individuals (≤40 years old, BMI >30) are already displaying reductions in blood vessel function. This study will test if the signals blood vessels use to increase blood flow are changing in these same subjects. Findings from this study may help create treatments to delay or prevent some of the negative effects of obesity on vascular health.
The investigators aim to show that single use negative pressure dressings can decrease the rate of wound complications in obese women (BMI > 40 kg/m2) undergoing cesarean delivery at a tertiary medical center by randomizing women to receive either a single use negative pressure dressing or the standard dressing after cesarean delivery.
Previous studies have shown that histological changes in the gastric mucosa between obese and non-obese individuals do exist. Understanding these histological differences (between obese and non-obese individuals) might elucidate obesity pathophysiology. However, the data is scarce and even contradictory. Even less is known about the histological characteristics of the duodenal mucosa in obesity and lean states, but several studies already performed hint for some differences. These differences might influence gut hormones composition and function and play a crucial role in the development of obesity and metabolic syndrome. To our best knowledge, in-vivo, human, real-time cellular level comparison of gastric and duodenal mucosa has never been done. This can be now accomplished with pCLE. pCLE, is composed from a miniature microscope assembled in the tip of an optical fiber. This optic fiber is then inserted through the working channel of a standard endoscope, bringing the microscope at the tip of the fiber to close proximity with the tissue. The system applies a blue-light laser that after staining with fluorescein (IV 2.5 ml, 10% fluorescein, once) provides a cellular-level, in-vivo, real time images: the concept of so called "optical biopsies". The system has been used as an auxiliary tool in GI-endoscopy in recent years. This technology has been shown to be useful in identifying objective histological features and even intramucosal bacteria in different tissues.
The primary objective of this study is to evaluate the Carboxipeptidase D (CPD) genotyping as a predictive biomarker of body weight and/or fat mass reduction in obese patients treated with perindopril. There is nonclinical and clinical evidence that a subgroup of human subjects may present a decrease in body weight and/or fat mass following treatment with perindopril. Although the individual characteristics that determine such effect are still unknown, Gene PreDiT SA (Biocant Park, Cantanhede, Portugal) discovered that certain genetic characteristics (e.g., single nucleotide polymorphisms (SNPs) of CPD gene) may play a role and potentially could serve as a potential predictive biomarker of response to perindopril. These promising results, along with the fact that perindopril is a medicine already in use in clinical practice, led Gene PreDiT SA to decide to proceed with the development of a theranostic approach for the treatment of obesity. Such theranostic approach consists on the use of CPD genotyping to identify obese subjects that could present improved body weight and fat mass reduction following treatment with perindopril. The current clinical trial aims to prove the concept and provide data to design further confirmatory studies. Additionally this study will evaluate the association between CPD SNPs genotypes and response to perindopril; the effect of perindopril in waist circumference, waist/hip ratio, and BMI and the tolerability and safety of perindopril in the study population.
Metabolic disorders including hypercholesterolemia and hypertriglyceridemia are present in climacteric women. Carduus marianus is a homeopathic medicine that traditionally has been used for hepatic diseases. It has been used for reducing hypercholesterolemia and hypertriglyceridemia also. The aim of this study is to investigate the most effective dose of Carduus marianus in centesimal scale (6cH, 12cH, 30cH, placebo) plus diet and exercise for reducing hypertriglyceridemia and/or hypercholesterolemia in climacteric women.
The investigators wish to study the effects of alcohol on three forms of bariatric surgery, Roux-en-Y gastric bypass (RYGB), sleeve gastrectomy (SG) and laparoscopic adjustable gastric banding (LAGB) and compare them with a non-surgical group. The surgery is not part of the clinical trial. If insurance does not cover the procedure, then the patient is responsible for payment of the surgical process. The investigators are doing pre and post surgery testing to provide a better understanding of the effect of bariatric surgery-induced weight loss on 1) alcohol absorption, distribution and elimination from the body, 2) the effects of alcohol on mood, and 3) the effects of alcohol on driving.
The purpose of this study is to evaluate the LINX device in patients who have previously undergone laparoscopic sleeve gastrectomy (LSG) for obesity and have chronic gastroesophageal reflux disease (GERD). The study will monitor safety and changes in reflux symptoms.
The purpose of this study is to study interactions between genes, lifestyle environmental factors like foods, nutritional supplements and non-invasive medical devices and health factors that can be measured without specialized medical equipment in order to develop lifestyle recommendations tailored to individual genetics for a host of common chronic health conditions.
