Opioid sparing anesthesia is extremely important in the post-operative obese population. With more and more obese patients entering the operating room a multi-modal approach to analgesia is crucial. Finding effective alternatives to opioid therapy is the rationale of this proposal. Literature involving ketamine and magnesium in bariatric surgical patients is very sparse.

This goal of this randomized controlled effectiveness trial is to compare the effectiveness of a peer-led health lifestyle intervention (Peer GLB) versus usual care services in two supportive housing agencies in New York City (Pathways to Housing [PTH] and Federation Employment and Guidance Service [FEGS]) serving diverse clients with serious mental illness who are overweight or obese. The intervention follows the Group Lifestyle Balance curriculum derived from the Diabetes Prevention Program and that has been shown to help people achieve clinically significant weight loss (equal to or greater than 5% weight loss of initial weight). The intervention will be delivered by trained peer-specialists employed at the supportive housing agencies and supervised by the study team. Peer GLB is a 12-month group intervention that focuses helping people lose weight by improving people's diet and increasing their physical activity and consists of weekly core group sessions (3 mo.), bi-monthly transitional group sessions (3 mo.), and maintenance monthly sessions (6 mo.). We plan to enroll 300 clients with serious mental illness who are overweight/obese (BMI equal to or greater than 25) from our two supportive housing agencies. Clients will be randomized to either the Peer-led healthy lifestyle intervention or usual care conditions. The primary outcome for this study is achieving clinically significant weight loss (equal to or greater than 5% weight loss from baseline weight) at 12 and 18 months post randomization. The secondary outcomes for this study include overall reductions in weight, waist circumference, blood pressure, and improvements in physical activity, self-efficacy, recovery and health-related quality of life. Repeated assessments will be at baseline, 6, 12 and 18 month post randomization. Primary Hypothesis: Peer GLB participants will have a higher proportion of persons achieving clinically significant weight loss (equal to or greater than 5% weight loss) at 12 and 18 months than UC participants. Secondary Hypothesis: At 6, 12, and 18 months post-randomization, there will be significant reductions in average weight, waist circumference, blood pressure, and significant improvements in physical activity, self-efficacy, recovery, and health-related quality of life in Peer GLB compared to UC.

This study will examine whether hesperidin, a major component of citrus fruits, affects how the body responds to insulin in healthy and obese people. Laboratory studies suggest that hesperidin treatment lowers blood pressure, lowers blood sugar and increases blood flow. This study will see if hesperidin improves insulin resistance or insulin's effects on blood flow in people with insulin resistance. Healthy normal weight or overweight people between 21 and 65 years of age may be eligible for this study. Participants are randomly assigned to take hesperidin or a placebo (inactive dummy pill ) for a 4-week treatment phase.

The population continues to increase in weight. Currently there are no guidelines in the dosing of cefazolin for the obese population. Standard dosing of cefazolin 2 grams for patients <120 kg and 3 grams for patients >120 kg is used as the dose for surgical prophylaxis. This makes no provisions for weight based dosing. There has been some recent data which states this might not be enough for the obese patients. The primary objective of this study is to determine if weight based dosing (30 mg/kg) of cefazolin as surgical prophylaxis for patients undergoing elective gastric bypass/laparoscopic Roux-en-y gastric bypass provides appropriate serum concentrations for a larger percentage of time than the current method of giving the standard 2 or 3 gram doses of cefazolin peri-operatively. The concentration of cefazolin in tissue will also be measured to help assess this question.

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.

The Alberta FYBER Study

May 2015 - December 2019
Too much body-fat has been linked to a low-grade inflammation throughout the body. This inflammation is thought to then cause different diseases, like heart disease and diabetes. A lower amount of inflammation is usually seen in people that follow a high fiber diet. A reason for this is the microbes that live in our gut. Fiber is a main food source for these microbes. This allows fiber to actually change the type of microbes that live in our gut. Also, when fiber gets fermented by these microbes, health-promoting waste products get released. We aim to determine how exactly our gut microbes contribute to the health properties of fiber. We hypothesize that fiber's health properties depend on how the gut microbes respond to the fiber. To test this, we plan to add four different fibers to the diets of healthy overweight and obese individuals for two months. We then will determine how the different fibers affect an individuals' health by looking at how different health markers change from adding the fiber. Following this, we will see how an individual's gut microbes respond to the added fiber. The response will be decided by looking at changes to the microbe community, as well as their ability to ferment the fibers. By connecting health outcomes to the gut microbes' response, we can test if the gut microbes' response to the fiber determines the fiber's ability to effect health. If we can understand how our gut microbes respond to different fibers and the importance of that response. Then we could personalize diets to have a greater impact on improving health.

This is an open label, single-dose, pharmacokinetic study in 9 obese and 9 age-, sex-, ideal body weight- matched non-obese subjects. Qualifying subjects who have completed an informed consent will receive a single intravenous dose of tedizolid with the collection of 11 blood samples over 72 hours post dose.

The purpose of this study is to evaluate the effect of a 7-month social marketing program - Our Year of Healthy Living - in improving preschool children's (3-4 years) diet and physical activity behavior. Our Year of Healthy Living will use social marketing approaches in the child care center to promote the use of healthy diet and physical activity behaviors by children, as well as their teachers and parents. The program will use visual cues, educational materials, activities, and a song to deliver targeted healthy behavior messages that connect the teacher, child, and parents. Centers will implement the Our Year of Healthy Living program in their classrooms over the course of a school year (October-April). Prior to initiation and after completion of the program, researchers will collect information about diet, physical activity, child body mass index (BMI), and center and home environment information from participants. From the beginning of the program to the end, children enrolled in the Our Year of Healthy Living program will have 1) a greater increase in physical activity and decrease in sedentary time, 2) improved diet, and 3) smaller increase in body mass index compared to children in centers that do not complete the program. Additionally, from the beginning of the program to the end, homes and centers that participate in the program will have greater improvements in scores on the home and center environment assessments compared to centers and homes that do not participate.
