Filter by:Background: - Being overweight may cause low-level inflammation. This inflammation may cause some of the medical problems of obesity, like high blood sugar (diabetes) and heart disease. This study will test whether a medication called colchicine can improve metabolism in adults who are overweight but have not yet developed diabetes. Objectives: - To learn whether colchicine improves sugar regulation and metabolism. Eligibility: - Healthy overweight adults18 to 100 years old. Design: - Participants must fast before each visit, including the screening visit. - Participants will be screened with blood tests,urine tests, medical history, and physical exam. They will have to drink sugar water, and have blood drawn to find out if they are healthy. - For visit 1, participants will have a medical history and physical exam and answer questions. They will have blood taken with an intravenous (IV) line, give urine sample, and give 2 stool samples.. - Also, subjects will get sugar water through one IV. Blood will be drawn from the other. This measures sugar and insulin levels. During this, participants will lie in a bed and can watch TV. - Participants will have a full-body X-ray, lying on a table while a camera passes over them. They will also have an abdominal CT scan, lying on a table that moves through a ring that takes pictures. - Participants will have a small fat tissue sample taken from their abdomen. It is like getting a mini-liposuction. - Participants will be given the study drug or placebo. They will take it twice daily for 3 months. - For visit 2, participants will have blood tests, urine tests, medical history, and physical exam. - For visit 3, participants will repeat the tests in visit 1.
The hypothesis of the present study is that physical training can oppose detrimental changes in cardiovascular and metabolic health associated with estrogen loss after menopause.
This study is a pilot study to investigate whether intake of lean or fatty fish, or lean meat would affect parameters related to health in healthy non-obese adults, and will serve as basis for future calculation of group sizes in coming studies. Participants consumed 750g/week of fillets of fish or meat for 4 weeks. Hypothesis: High intake of either lean or fatty fish will not affect serum concentrations of lipids and inflammatory markers as well as improve glucose tolerance during the 4 week intervention period when compared to lean meat intake.
People with type 1 diabetes need regular insulin injections or continuous delivery of insulin using a pump. Keeping blood sugars in the normal range is known to reduce long term complications. However, achieving treatment goals can be very difficult due to the risk of low glucose levels (hypoglycaemia). One solution is to use a system where the amount of insulin injected closely matches the blood sugar levels on a continuous basis. This can be achieved by what is known as a "closed loop system" where a small glucose sensor placed under the skin communicates with a computer containing an algorithm that drives a subcutaneous insulin pump. Previous studies conducted under carefully controlled clinical research facility environment, in Cambridge, United Kingdom, as well as several other centres have shown that closed-loop glucose control is superior to usual insulin pump therapy. The next logical step in the development pathway is to test closed loop systems in the home environment. An essential requirement for conducting closed-loop studies outside clinical research facility is an automated system where wireless data transmission takes place between the glucose sensor and insulin pump. The purpose of the present study is to evaluate the efficacy and safety of automated overnight closed-loop, in children and adolescents with type 1 diabetes, using a novel system which has greatest potential for use in the home setting. The study will take place at a clinical research facility on two occasions, using a standardised protocol. The performance of the closed-loop system will be evaluated on day 1 of continuous glucose monitoring (CGM) sensor life as compared to on days 3 to 4 of sensor life. Data and experience gained from this study will be used for further refinements and development of the system for future home use.
Montmorillonite (MONT) is a phyllosilicate layered mineral with unique physicochemical properties, such as swelling and cation exchange capability. The aim of this project is to study, in healthy volunteers, the in vivo ability of MONT to reduce protein intestinal uptake. Furthermore, the study analyzed in vitro the MONT ability of immobilizing proteins.
This is a phase 1, randomized, double-blind, placebo-controlled, multiple ascending dose study to assess the safety, tolerability, pharmacokinetic (PK), immunogenicity, and pharmacodynamic (PD) effects of REGN1500 in patients with a metabolic disorder.
Insulin resistance is closely associated with apparition of type 2 diabetes mellitus; it is an independent risk factor and predicts future cardiovascular events. Hyperinsulinemic euglycemic clamp is a validated method to assessment of insulin resistance and It is also the gold standard technique. However, the complexity and length of this technique render it unsuitable for routine clinical use. In this study, the investigators use a new technique to provide precise, objective, fast and automated quantification of insulin resistance with camera SPECT. They compare the results with those of the measurement of hyperinsulinemic euglycemic clamp in population with or without insulin resistance. The proposed study is to validate this new non-invasive imaging technique for evaluation of insulin resistance in patients with or without insulin resistance with a comparison with hyperinsulinemic euglycemic clamp.
Obstructive sleep apnea(OSA) is an important identifiable cause of hypertension. Previous study has suggested that OSA significantly increases cardiovascular morbidity and mortality, especially in patients with pre-existing cardiovascular disease.The standardized treatment of moderate/severe OSA is continuous positive airway pressure (CPAP). Most of short-term trials indicated that CPAP treatment reduced BP in patients with OSA. But relevant studies have a relative short duration with only but few more than one year. In our opinion, they are not sufficient to detect the real effect of CPAP on reduction in BP. Besides, the impact of OSA on metabolic disorder is still unclear.We hypothesized that long-term CPAP treatment could reduce blood pressure and improve metabolic disorder in patients with coronary heart disease (CHD)and OSA.
The purpose of the study is to determine whether carrier status for any type of glycogen storage disease (GSD) predisposes the carrier to GSD markers, like high cholesterol, by testing blood, urine, and saliva samples.
Peritoneal Dialysis (PD) is a commonly used treatment for end stage renal failure, and the most commonly used dialysate contains unphysiological amounts of glucose, a high proportion of which is absorbed. Recent analysis of the Global Fluid Study, has established that in non-diabetic prevalent patients on PD a random glucose level is dependent on dialysate glucose load and is a predictor of death. By utilising clinical data and additional biosamples collected for the NIHR funded PD-CRAFT study, the investigators aim to confirm this finding, define the relationship between dialysate glucose exposure according to prescription regimes and glycaemia, define the most useful biomarker to monitor glycaemia , and establish the role that impaired insulin sensitivity plays in blood glucose levels. Furthermore the investigators will explore the hypothesis that insulin resistance is associated with disturbance of the carnitine/acetyl-carnitine equilibrium that might benefit from intra-peritoneal carnitine supplementation. PD-CRAFT is an observational cohort study of 3000 prevalent PD patients collecting detailed clinical data, including glucose exposure and samples of dialysate. and blood which will be stored in the UK BioCentre. Follow up is for up to 2 years or endpoint (death, technique failure). Multivariate regression will be used to establish determinants of the non-fasting blood glucose and other measures of glycaemia, in particular different dialysis regimes, (e.g. modality, dwell lengths, fill volumes, and dialysate type and concentration specifically seeking to identify prescriptions that minimise the systemic effects) combined with measures of insulin resistance. The investigators will establish whether blood glucose predicts survival in an adjusted analysis (~300 endpoints needed) using Cox regression and explore the relationship of other biomarkers to survival.
