Filter by:The goal of this observational prospective project is to study the metabolic alterations during normal and complicated pregnancies, obtaining an early detection of metabolic changes, offering new insights into future prevention and treatment strategies for both mother and offspring. Primary objectives: - measurement of maternal blood adipokine levels, during the first trimester of pregnancy, in two groups of women (high and low risk), in order to identify early markers which, in conjunction with the medical history, can identify women at increased risk of developing GDM - ultrasound measurement of adipose tissue deposits at ectopic sites, comparing low- and high-risk women, and assessing the effect of pregnancy on these deposits. - Identification, by targeted ultrasound assessment, of fetuses at increased risk of macrosomia. Secondary objectives: - Evaluation of the prevalence of GDM and its complications in a population of low- and high-risk women. - Evaluation of neonatal complications in children born to low- and high-risk mothers (need for resuscitation, hypoglycaemia, hypocalcaemia, admission to neonatal intensive care unit). The participants will be recruited during first trimester ultrasound after signing the informed consent.
The goal of this observational study is to compare serum glucose and lipid metabolism levels between health volunteers and vitiligo patients. The main question it aims to answer is whether vitiligo is related to glucose and lipid metabolism disorders. Participants will complete a vitiligo questionnaire and test serum levels of indicators related to glucose and lipid metabolism. Researchers will compare vitiligo patients with healthy volunteers to see if there is a correlation between vitiligo and disorders of glucose and lipid metabolism.
The purpose of this study is to analyze the effects of GLP-1RA on blood glucose, body weight, glucose and lipid metabolism and fat distribution in overweight/obese patients with type 2 diabetes mellitus.
This study is a prospective, randomized, open-label, multi-center trial. The primary objective of the study is to assess whether XZK 1200mg/d, compared to atorvastatin 20mg/d, has a favorable impact on HbA1c levels at 24 weeks of treatment in dyslipidemia patients with prediabetes
GLADS is a cross-sectional, observational study assessing free-living diet, physical activity, sleep, and glucose profile over a 2-week period in healthy adult men and women.
Caffeine containing energy drinks (CCED) are beverages that typically contain mixtures of simple sugars, caffeine and may contain vitamin, mineral and/or herbal preparations. In Canada, the consumption of CCEDs among adolescents is a regular occurrence and a common part of the everyday diet. Contributing to the obesity epidemic in youth is the consumption of energy drinks; yet no data on the metabolic responses to CCEDs exists. This study will examine the metabolic implications of CCED consumption in adolescents, aged 13-19 years. The investigators hypothesize that CCEDs will impair glucose tolerance by ~30% in lean adolescents and the primary cause of the insulin resistance will be caffeine. Obese individuals will experience a similar level of glucose impairment, but a greater rise in blood glucose compared to their lean counterparts (i.e. higher starting glucose level). For many, this additional, caffeine-induced rise will expose them to hyperglycemia, putting some individuals in the glucose intolerant or transient diabetic range. It is hypothesized that continued metabolic insult resulting from CCEDs may predispose susceptible individuals to chronic metabolic diseases later in life. The investigators will also examine the genetic basis of caffeine-induced glucose intolerance. This gene-diet interaction could explain why caffeine may be much more metabolically harmful for some individuals compared to others. The study of 'metabolomics' will also be utilized to analyze caffeine and caffeine metabolites such as theobromine, theophylline, and xanthine. This will be accomplished using Nuclear Magnetic Resonance (NMR) spectroscopy. Results from this study will have the potential to alter current perceptions that CCED are 'harmless' and will have far reaching implications for both medical professionals and legislators alike.
Hyperglycemia is a well-known cardiovascular risk factor. It has also been shown that episodes of hyperglycemia increase the risk for cardiovascular diseases despite return to normoglycemia, a phenomenon termed 'glycemic or metabolic memory'. The molecular mechanism underlying this phenomenon remains unclear. Cardiovascular events, such as myocardial infarction and stroke are caused by atherosclerosis, which is characterized by low grade inflammation of the vascular wall, including accumulation of innate immune cells such as monocytes and macrophages. The investigators hypothesize that chronic hyperglycemia shifts intracellular metabolism of innate immune cells towards glycolysis and changes the epigenetic state of (progenitors of) innate immune cells (monocytes and macrophages), which reprograms these cells towards a more aggressive, pro-atherogenic phenotype, thereby accelerating atherosclerosis. In this study, the investigators aim to test this hypothesis. This research will reveal whether the innate immune cells of patients with chronic hyperglycemia show a durable shift in intracellular metabolism and epigenetic changes and whether this associates with vascular inflammation.
Overview- In this study, overweight or obese, sedentary participants (age=35-55 years, n=20) will be randomized to a 12-week control period or an aerobic exercise intervention. Those randomized into the control group will then complete the exercise intervention subsequently. The planned energy expenditure per week of exercise will be 10-12 kilocalories per kilogram of body weight per week. Participants will complete three non-consecutive exercise sessions per week. Body weight, resting metabolic rate via indirect calorimetry, peak oxygen consumption (VO2peak) through graded exercise testing, fasting blood samples, CGM, sleep and dietary habits via self-report, and physical activity monitoring will be completed at prior to and following the aerobic exercise intervention.
After meals, the level of glucose rises in the circulation. In some individuals who are overweight and older, blood glucose can rise to levels which can damage tissues and cause health problems. Usually the hormone insulin, released from the pancreas, effectively lowers blood glucose. However, in overweight and older people insulin is less effective. Certain foods can lower the rise in blood glucose, particularly proteins. This works by increasing the release of a hormone from the gut called Glucagon-Like Peptide 1 (GLP-1), which in turn increases the release of insulin. A Component of milk left over after cheese making, termed Whey protein, is particularly good at releasing GLP-1. Whey protein is used as a food additive and taken as a supplement to help build muscle. Whey protein is a mixture of proteins which the investigators have modified to be more effective at lowering blood glucose. Using laboratory tests the investigators identified a protein present in Whey that does not increase levels of GLP-1 and removed it. It's removal raises the levels of other proteins which are more effective. In this study, the investigators would like to test the effectiveness of the "modified" whey protein. To do this, 30 older, overweight volunteers will be recruited and given the modified whey protein, a normal whey protein or a mixture of amino acids and then a breakfast meal to raise their blood glucose levels. These drinks will be given in a randomised sequence 1 week apart. On each visit, blood samples to measure blood glucose and related hormone levels will be taken. As GLP-1 can also have an effect on appetite, the investigators will measure the effect of the modified whey protein on subsequent appetite in the volunteers by asking them how hungry they feel.
In this explorative randomized clinical study, the investigators aim to study metabolic, cellular, and molecular changes that occur during weight loss in obese subjects with and without type 2 diabetes. Using novel "imiomics" (imaging technique using PET/MR bioinformatics) analyses to examine possible metabolic differences between energy restricted diet and gastric by-pass surgery on whole-body and tissue specific insulin sensitivity, glucose tolerance, metabolite and protein profiles, fatty acid metabolism, ectopic fat content, and gene expression in adipose tissue. This study aims to identify novel biomarkers and drug targets for type 2 diabetes as well as validate promising and established biomarkers in an interventional model for improved glucose metabolism.
