Filter by:In this study, we will address cost barriers to participating in summer programs and hypothesize this will lead to marked improvements in children's obesogenic behaviors and a reduction in excessive, unhealthy weight gain over summer.
The objective of this study is to determine the homeostatic mechanisms that counteract weight gain in response to experimental overfeeding.
The relation between obesity and stroke recurrence is still under debate. In this study it has been sought whether baseline obesity is associated with recurrent stroke and major cardiovascular events in a long-time period.
Comparison of the prevalence of obstructive sleep apnea (OSA), measured by polysomnography in normal weight patients with central obesity by body mass index (BMI) and waist hip ratio (WHR), with normal weight patients without central obesity by BMI and WHR. Evaluation of arterial stiffness and vascular age in normal weight patients with central obesity and in normal weight patients without central obesity. Determination of the exercise response characteristics in OSA patients.
The study looks at how the study medicine (NNC9204-1177) affects other medicines in the body. Participants will get the study medicine and 5 other medicines which have all been approved by the authorities. Participants will get 1 injection of the study medicine each week for 11 weeks. The study medicine is injected under the skin in the stomach area. All injections will be given by study staff. Participants will get 5 medicines as tablets, capsules or syrup to be taken with water at the beginning of the study and after 10 weeks of treatment with the study medicine. The study will last for about 4 months. Participants will have 14 visits to the clinic with the study staff and study doctor. Participants will have blood draws and 2 different kinds of electrocardiograms taken during the study. They will be asked about your mental health. People who use any medication, including herbal products, cannot take part in the study. Women cannot take part if pregnant, breast-feeding or planning to become pregnant during the study period or if they use birth control pills or other hormonal birth control products.
Excessive fat in the liver is associated with impairments in metabolic health. Reducing the amount of carbohydrates and fat both have been shown to reduce liver fat. However, not only the amount fats and carbohydrates, but also their quality have been shown to influence liver fat. Diets high in saturated fatty acids (SFA) and diets with a high glycemic index (GI) have been shown to increase liver fat content. However, available data from human dietary intervention studies is limited and these studies did not reflect a realistic diet. In the present study a combination of low GI/SFA on the one hand and high GI/SFA on the other hand is used to reflect realistically a healthy and an unhealthy diet as they are actually consumed by the Dutch population. The primary objective of this study is to investigate whether a two-week low compared to high GI/SFA diet reduces liver fat content. In addition, it will be investigated whether a two- week low compared to high GI/SFA diet reduces DNL, lowers the 24-hour glycemic response, lowers hepatic glycogen content, increases hepatic fat oxidation and changes hepatic lipid composition. Furthermore, the metabolic response to a meal (metabolites related to energy metabolism and substrate oxidation) will be studied upon the low and high GI/SFA diets.
This is a phase I, open-label clinical trial evaluating the safety and efficacy of deoxycholic acid injection for reduction of upper inner thigh fat.
The biggest challenge in obesity management is maintaining weight loss in the long-term. Currently, bariatric surgery is the most effective treatment, leading to sustained weight loss that is not yet achievable with lifestyle intervention (e.g. diet). The reasons behind its success is still not clearly understood, but beneficial changes in the homeostatic and hedonic appetite systems (the two major physiological regulators of appetite), along with the microbiome (known to have a mediatory effect on appetite) have been shown to occur after bariatric surgery. These alterations are in opposition to what is seen after diet-induced weight loss. Today, the component of appetite regulation that drives bariatric surgeys' long-term success is still unknown. By comparing a lifestyle and surgical intervention in parallel, the investigators can observe the impact of a similar magnitude of weight loss on these three domains of appetite regulation simultaneously, thereby illuminating the mechanisms behind bariatric surgerys' success.
A screening modality to help categorize obese pregnant women as high or low probability for heart failure would be helpful in the evaluation of the obese pregnant women with dyspnea. Outside of pregnancy, measurement of brain natriuretic peptide (BNP) or amino-terminal pro-brain natriuretic peptide (NT-proBNP) is recommended in the evaluation of acute dyspnea and in the diagnosis of heart failure. During pregnancy, elevated BNP has been associated with adverse cardiovascular events, while normal BNP levels have been observed in healthy pregnancies. While BNP levels outside of pregnancy have been shown to be lower in obese patients variations in BNP levels by body mass index (BMI) in pregnancy have not been studied. Before BNP can be deemed a reliable screening test for heart failure in obese pregnant women, normal BNP values in the setting of obesity and pregnancy need to be established. We therefore propose the following specific aims: Objective 1: Compare mean plasma NT-proBNP levels in the third trimester, immediately postpartum, and at 4-6 weeks postpartum between obese pregnant women without cardiovascular disease and non-obese pregnant women without cardiovascular disease. We hypothesize that mean plasma NT-proBNP levels in obese pregnant women without pre-existing cardiovascular disease will be significantly lower than levels in non-obese pregnant women. Objective 2: Assess whether plasma NT-proBNP levels in pregnancy correlate with BMI. We hypothesize that there will be an inverse correlation between plasma NT-proBNP levels and BMI in our pregnant cohort similar to that seen outside of pregnancy.
This study seeks to determine whether artificial sweeteners in the context of diet soda may alter the brain's response to food cues and thus impact appetite.
