The study will look at how two different forms of semaglutide reach and stay in the blood after injection. None of the two forms of semaglutide have been approved by the authorities to treat obesity, but it has been approved as a treatment for diabetes mellitus. Participants will get 1 of the 2 forms of semaglutide - which one is decided by chance. Participants will get the medicine as an injection under the skin of the belly using a pen-injector. The type of pen-injector is different for the two forms of semaglutide. The study staff will teach participants how to inject the medicine. Participants will take an injection once a week and will get a total of 21 injections of study medication. The study will last for about 27-30 weeks. Participants will have 25 study visits with the study doctor. For 2 of the visits, participants will stay in the clinic for 3 days and 2 nights. Participants may have to stop the study if the study doctor thinks that there are risks for their health. Women cannot take part if they are pregnant, breast-feeding or planning to become pregnant during the study period.
This is a prospective non-randomized unicentric clinical trial, characterized by the inclusion of obese (BMI> 35) male with subfertility (sperm count showing low sperm counts and / or motility and / or morphology and / or DNA fragmentation). Patients selected at the endocrinology obesity HC-FMUSP outpatient will be submitted to very low calorie diet (VLCK) for 6 months, being reassessed clinically and laboratorially monthly.
Food insecurity is associated with an increased risk of obesity. The availability of a default option (i.e., option a consumer selects if no active choice is made) has been shown to effectively nudge consumer behavior. An online default option (i.e., prefilled grocery shopping cart) was previously shown to positively impact the food purchases of individuals with food insecurity.The present study aims to extend these findings bye examining efficacy of an online default option in enhancing the nutritional quality of online grocery purchases in individuals with food insecurity over the course of a month.
The aim of this trial is to examine the feasibility of a larger-scale intervention study (regional study in schools run by the Ministry of Education) to increase the consumption of fruits and vegetables in schools towards reducing percentages of childhood obesity prevalence rates by at least 0.5% every two years for all children, using an organic-based healthy eating intervention package for primary school children and their parents.
Data on pharmacokinetics of rivaroxaban after bariatric surgery and in morbid obesity are sparse. The aim of this study is to assess the pharmacokinetic and pharmacodynamic parameters of rivaroxaban, used at a therapeutic anticoagulant dose, in patients with previous bariatric surgery, with sleeve gastrectomy or gastric bypass, and in morbid obese subjects. Four groups of 16 subjects per group are studied: Morbid obese subjects / Subjects who have undergone gastric bypass surgery / Subjects who have undergone sleeve gastrectomy surgery / Non-operated control subjects matched for age and BMI with operated subjects. All patients (obese, surgical patients, and controls) will receive rivaroxaban 20mg once daily during 8 days. Blood samples will be taken predose (Baseline) and 0.5, 1, 2, 3, 6, 9, 12 and 24h post rivaroxaban administration at day1 and day8. PK and PD parameters will be compared between groups in order to explore the impact of bariatric surgery, type of surgery and body mass index on the pharmacological profile of rivaroxaban.
The study team's objective is to test the effect of supermarket discount levels on fruit and vegetable (F&V) and non-caloric beverage purchasing and consumption, as well as health outcomes. The study team will implement this economic intervention in a local supermarket chain to assess the effects of a 32-week intervention of fruit and vegetable (F&V) and non-caloric beverage discounts of 30%, 15%, and 0% (control group) on purchasing, dietary intake, and health outcomes, including body weight and composition, blood pressure, and biochemical markers of cardiovascular disease risk. The 32-week intervention will be preceded by an 8-week baseline and will have a follow-up period of 16 weeks. There will be no discounts in effect during the baseline and follow-up periods.
There is a lot of research on weight loss. In spite of the research on the subject, obesity is a growing disease all through the world. The results of recent reviews and meta-analyzes show that psychological interventions had small effect on weight loss. The investigators propose a different approach to changing eating behaviors with relevance to weight management and hypothesize that participants in the active interventions will significantly improve their eating behaviors than the ones in the control group. The results will improve the psychological interventions for weight loss.
The purpose of the present study is to determine if prebiotic supplementation can, through changes in the intestinal gut microbiota, lead to improvements in knee function and physical performance and reduce knee pain in adults with obesity and idiopathic metabolic knee osteoarthritis. We hypothesize that prebiotics will reduce systemic and local (knee joint) inflammation, thus improving knee function, lower pain medication use, and enhance performance of daily life activities.
Poor diets are known risk factors for chronic diseases, and in recent years, food labelling has been increasingly sought-after as a cost-effective intervention to help stem the rising trend in chronic diseases. In efforts to promote a healthy diet, the Singapore Health Promotion Board (HPB) supplements traditional nutrition labelling with the Healthier Choice Symbol (HCS), which identifies food items within a specific category of foods as healthier choices. The original logos were enhanced to include additional information focusing on particular macronutrients, taking one of two themes; it either indicates that a product contains more of a healthier ingredient, or less of a less healthy ingredient. However, to date, no published studies have assessed the role of the original and enhanced HCS logos in influencing food choices. There is a lack of scientific evidence on the role of the existing symbols in assisting consumers make healthier food purchasing decisions. There are also concerns over the unintended consequences of health claims made based on a single aspect of nutrient content, without considering other aspects. That is the goal of this effort. Specifically, the investigators propose to conduct the following: Use a three arm randomized controlled trial (RCT) and an experimental fully functional web-based grocery store to assess the causal effect of the new HCS logos on measures of diet quality either alone, or in combination with a complementary front-of-package (FOP) label: Physical Activity Equivalents (PAEs), which provides information on how long one would need to engage in a certain activity (e.g., jogging) to burn off one serving of the product. The investigators hypothesize that the greatest reduction in calories per serving (primary outcome) will occur in the HCS plus PAEs arm, followed by HCS only, and no logo control arm.
