Filter by:The aim of this study was to compare the metabolic effects of consuming whole barley bread and whole wheat bread, in healthy subjects. Also, to investigate the effect of whole grain flour on mineral status.
This study aims to assess the effects of hazelnuts, cocoa, and the combination of both on vascular reactivity and metabolic profile. Participants, divided in six groups, will receive one of these breakfast integrations for 14 days: group 1) 30 g peeled hazelnuts; group 2) 30 g unpeeled hazelnuts; group 3) snack with 30 g peeled hazelnuts; group 4) snack with 2.5 g cocoa powder; group 5) snack with 30 g peeled hazelnuts and 2.5 g cocoa; group 6) empty snack, control group.
The aim of this study is to compare the effects of emulsification and lipid droplet size on gastric emptying rate, and to determine if the change in gastric emptying rate can in turn influence postprandial glycemic, insulinemic and lipidemic responses.
Growth hormone (GH) induces fat metabolism. The mechanisms underlying the fat metabolizing effects of GH remain elusive. However, it is known that insulin suppresses fat metabolism, and GH inhibits the expression of certain insulin-dependent signaling proteins. We therefore hypothesize that the fat metabolizing effects of GH depend on abrogation of insulin-dependent signaling pathways. In order to investigate the fat metabolizing effects of GH, we'll analyze consecutive adipose tissue biopsies taken after GH exposure and GH blocking, respectively. Knowledge of the effects of growth hormone and fat metabolism can in shot-sight as well as in long-sight have great importance for the understanding of growth disorders from overweight and type 2 diabetes to malnutrition and eating disorders.
Growth hormone (GH) is essential for longitudinal bone growth and somatic development. These protein anabolic effects require sufficient nutritional supply. During fasting and caloric restriction GH predominantly promotes fat metabolism. GH counteracts the effect of insulin in many tissues, of which insulin-stimulated glucose uptake in skeletal muscle has been most extensively studied. Substrate competition between elevated free fatty acids and glucose is suggested as a mechanism, and this hypothesis can be tested mechanistically by means of acipimox, which is a nicotinic acid that suppresses the fat metabolizing effects of GH. The hypothesis is, that the suppressive effect of GH on insulin-stimulated glucose uptake in skeletal muscle is obviated by acipimox-induced inhibition of fat metabolism. In order to investigate this, eight adult hypopituitary patients with documented GH-deficiency will be studied in the presence and absence of GH and acipimox, respectively, and biopsies from skeletal muscle and subcutaneous adipose tissue will be analyzed. Knowledge of the effects of growth hormone and fat metabolism can in shot-sight as well as in long-sight have great importance for the understanding of growth disorders from overweight and type 2 diabetes to malnutrition and eating disorders.
The purpose of this study is to evaluate the feasibility of using a quantitative EEG method to evaluate neurodevelopment in newborns and to evaluate whether subtle neurodevelopmental deficits can be detected in newborns from mothers with gestational diabetes mellitus (GDM) compared to control newborns. The second purpose of this study is to determine whether cord blood concentration in docosahexaenoic acid (DHA), an omega-3 fatty acid, is similar in neonates of well-controlled mothers with gestational diabetes mellitus (GDM) compared to control mothers, and to evaluate whether this contributes to neonates neurodevelopment status.
In this pre-post observational study, the investigators will enroll and follow a cohort of about 50 adults undergoing sleeve gastrectomy surgery for weight loss. Pre-operatively and at 6 and 12 months post-operatively, the investigators will use state-of-the-art metabolic and imaging techniques to evaluate calcium metabolism and skeletal health. Specific outcomes include intestinal calcium absorption capacity, bone mineral density (BMD) assessed by dual-energy X-ray absorptiometry (DXA) and quantitative computed tomography (QCT), and bone structure assessed by QCT and high-resolution peripheral QCT (HR-pQCT).
Objective: To compare short-term and medium-term effectiveness of a multimodal program that integrates a program of therapeutic exercise, medication review, adequacy of diet and health education, compared with standard medical practice in improving neuromuscular and physiological status on frail elderly. Another aim is to analyze the maintenance of these effects by monitoring long-term (12 months) from the start of the intervention. Design: Randomized controlled trial Scope / Study subjects: recruited frail elderly in Basic Health Zone of Malaga. Methods: The subjects to be included in the study (after meeting inclusion / exclusion) will be randomized into two groups: a control group whose intervention will be to review medication + adequacy of diet + health education (physical activity recommendation (within a comprehensive advice on healthy lifestyles) and an experimental group whose intervention will be a Multimodal Intervention: therapeutic exercise + review medication + adequacy of diet + health education program. Sociodemographic, Clinical and monitoring Variables will be collected at baseline. Moreover, tracking variables will be collected at 2 and 6 months after starting the intervention and at 3 and 6 months after the end of the intervention (monitoring). The monitoring variables that will be measured are: BMI , general health, fatigue, brittleness, Motor Control, Attention - Concentration - Memory, Motor Memory , spatial orientation, grip strength, balance (static - semi-static and dynamic ), gait speed and metabolomic variables. One descriptive analysis of the sociodemographic variables of the participants will be performed. Further the change on the variables intra-subjects (pre-post intervention) and inter-subjects (experimental group vs control group) will be calculated. For the intra-subject analysis will be performed a ANOVA-one factor analysis. The intersubject outcome variables will be compared between the two groups in each moments of data collection, using the student t-test or Wilconxon (depending of the sample distribution). The level of significance was set at P ≤ 0.05.
The HEPAFIT Study aims to examine whether a 6-months physical education program has benefits on hepatic metabolism and cardiovascular health as well as on selected physical fitness and mental health outcomes among adolescent overweight/obese from Bogota, Colombia.
In healthy individuals, the body responds to glucose (sugar) ingestion by reducing the amount released from the liver. At the same time, skeletal muscles increase the rate at which they remove the glucose from the bloodstream, via the actions of the hormone insulin. This ensures that blood glucose levels remain in a controlled range. However, in developed countries, diseases such as metabolic syndrome and type 2 diabetes are becoming prevalent, due to dietary modifications and a reduction in physical activity. As one of the prominent barriers to regular physical activity is a lack of time, finding ways to maximize the health benefits of exercise is a priority for researchers. The investigators want to understand potential differences in the effects of six weeks of aerobic training, with the exercise performed either after breakfast or after a prolonged fast. Specifically, this research aims to investigate whether there is a difference in the change in processes implicated in glucose regulation and secondly, in subsequent eating and physical activity behaviors. By investigating these changes this work will explore how exercise and nutrition can be optimized to benefit health and weight loss.
