Filter by:The purpose of this study is to measure blood glucose variation in youth prior to and after participation in a healthy lifestyle intervention program. The hypothesis is that youth with more severe obesity and those further along in puberty will have more glycemic variability, and that glycemic variability will be improved by participation in the lifestyle intervention program.
The purpose of this study is to investigate small intestinal remodeling and reprogramming of glucose metabolism in patients with Type 2 Diabetes Mellitus (T2DM) who undergo laparoscopic Roux-en-Y Gastric Bypass (RYGB). Our specific goal is to determine if the gene and protein expression levels of GLUT-1 are up regulated in the Roux limb and whether this is a major mechanism for the remission of T2DM following RYGB. The two aims of the study are: 1) to demonstrate that the basement membrane glucose transporter 1 (GLUT-1) is upregulated in the Roux limb following RYGB, and 2) to demonstrate that the upregulation of GLUT-1 is a major mechanism for the improvement in glycemic control observed in T2DM patients undergoing RYGB.
The investigators hypothesize that staple line reinforcement will result in a higher leak pressure than a non-reinforced staple line closure in the resected gastric specimens from laparoscopic sleeve gastrectomy. The primary endpoint of the study is leak pressure after various staple line treatments. The investigators will also analyze the most common site of specimen leak, association of stomach thickness to leak, association of stomach thickness to performance of the staple line techniques, and a cost analysis.
The purpose of this study is to test an intervention that uses home console video games to encourage increased physical activity among postmenopausal breast cancer survivors.
A 20 episode video game called Mommio simulates parent-child feeding interactions for parents of 3-5 year old children within a storyline addressing a problem commonly reported by parents (getting their 3-5 yo to taste a vegetable, which is often a first step toward eating the vegetable), thereby training parents in effective food parenting practices. This research evaluates whether the 20 episodes targeting barriers identified by parents across five levels of difficulty influences vegetable parenting practices and children's dietary intake. We had to discontinue the study since changes in commercial availability of game development software required reprogramming and available funding did not allow for completion of game programming. Thus, no game evaluation was possible.
The purpose of this study is to verify if postprandial walks are effective in obese pregnant women, as regards to gestational weight gain and typical diseases of that period, as gestational diabetes and preeclampsia. Perinatal outcomes will be observed, such as macrosomia, shoulder dystocia and fetal death.
The primary purpose of this study is to quantify activation of regions of the brain associated with taste, appetite, and reward after viewing high sugar and high fat (HS/HF) images compared to control images following ingestion of (1) an artificially sweetened solution, (2) a sucrose solution, and (3) a tasteless control solution in normal weight vs. obese women. This is a repeated measures study design; hence, data are collected on three days corresponding to the three solutions. Body mass index (BMI) is a between subjects measure. 1. After consuming an artificially sweetened solution and a sucrose solution compared to a tasteless solution, viewing HS/HF food images vs. control images will result in higher activation of taste pathways (frontal operulum and anterior insula (FO/AI)) in the brain. 2. After consumption of a sucrose solution compared to an artificially sweetened solution and a tasteless solution, viewing HS/HF food images vs. control images will result in higher activation of regions of the brain associate with appetite (hypothalamus). 3. After consumption of a sucrose solution compared to an artificially sweetened solution and a tasteless solution, viewing HS/HF food images vs. control images will result in higher activation of regions of the brain associated with reward [amygdala, anterior cingulate cortex (ACC), Orbitalfrontal Cortex (OFC), and ventral tegmental area (VTA), striatum, insula] in obese but not normal weight women. After consuming an artificially sweetened solution compared to a tasteless solution, viewing HS/HF images vs. control images will result in no differences in activation of reward pathways of the brain.
The primary purpose of this study is to quantify activation of regions of the brain associated with appetite and reward after viewing high sugar and high fat (HS/HF) images compared to control images following long-term aerobic exercise. 1. After long-term aerobic exercise compared to a no-exercise control group, viewing HS/HF food images vs. control images will result in higher activation of regions of the brain associate with appetite (hypothalamus). 2. After long-term aerobic exercise compared to a no-exercise control group consumption of a sucrose solution compared to an artificially sweetened solution and a tasteless solution, viewing HS/HF food images vs. control images will result in lower activation of regions of the brain associated with reward [amygdala, anterior cingulate cortex (ACC), Orbitalfrontal Cortex (OFC), and ventral tegmental area (VTA), striatum, insula] in overweight and obese men and women. Exploratory Aims As exploratory aims, investigators will test a preliminary brain connectivity analysis.
Greater time spent in sedentary behaviors, independent of physical activity level, can increase risk of morbidity and mortality. Objective assessments indicate that bariatric surgery patients spend large amounts of time in sedentary behaviors. The present study is the first to test whether a mobile health (mHealth) approach that employs widely adopted smartphone technology to monitor and modify sedentary behaviors as they occur is a feasible and acceptable method of reducing sedentary time in these patients and other obese populations.
Overweight and obese patients will be recruited and randomly assigned to two groups of intervention. To the first group [sulphate-bicarbonate-calcium water and low-calorie diet (SW-D)] will be administered "Acqua Santa di Chianciano"®, associated to a personalized low calorie diet, while the second group [tap water and low-calorie diet (TW-D)] will follow the personalized low calorie diet but will be asked to drink the same quantity of tap water, over a 4 week period. Stool samples will be collected and analyzed for changes in gut microbiota composition. Patients' body weight will be recorded at the beginning and at the end of the study.
