Filter by:Insulin resistance can be assessed by the euglycaemic clamp technique. To date, this is the golden standard, but it is not suited for clinical practice. A 13C glucose breath test will be tested as a valid alternative. The curve of the exhaled 13C CO2 as a function of glucose metabolism can be correlated to the curve of the glucose disposal rate obtained via the clamp technique.
The purpose of this study is to define the effect of ultrasound exposure of the liver in the region of the porta hepatis on glucose homeostasis and insulin resistance in healthy subjects.
The first aim of this study is to describe maternal hormonal and inflammatory changes during pregnancy in women that differ metabolically (limited to women with type 2 diabetes, gestational diabetes and/or overweight). The second aim of this study is to examine maternal hormonal, inflammatory and metabolic factors associated with insulin sensitivity in human pregnancy.
Impaired fasting glucose (IFG) is a condition that precedes diabetes and increases the risk of developing it. Studies support the hypoglycemic effect of Cynara cardunculus (Cs) extracts due to the content of chlorogenic acid, which is a potent inhibitor of glucose 6-phosphate translocase and of dicaffeoylquinic acid derivatives that modulate the activity of alpha-glucosidase. Given this background, we investigated whether a new highly standardized Cs extract could improve glycaemic control, insulin sensitivity and other metabolic parameters (total, HDL and LDL cholesterol, Triglycerides, ApoB, ApoA, waist circumference, Visceral adipose tissue by DXA) in overweight subjects with newly diagnosed IFG.
To evaluate the effect of estradiol with or without a prior gonadotropin releasing hormone analogue on insulin sensitivity and vascular function in transgender females compared to cisgender controls.
Assessment of Gastric Bypass combined with Vertical Sleeve Gastrectomy as primary treatment for patients with severe clinical obesity. Average percentage of total weight loss and percentage excess weight loss will be computed at 6 months, one year and then annually. Comorbid conditions, quality of life measures, appetite and satiety measures and adverse events will be tracked.
This study is investigating the effect of different intensities of exercise on levels of the hormone, ghrelin. In addition, we will be examining the relationship between any exercise induced changes in ghrelin and insulin sensitivity, obesity, and vascular function.
This is a 12-month, single center, three-arm parallel design, double-blind, randomized clinical trial, to compare the effects of supplemental dietary fiber and metformin (MET) alone and in combination over 12 months on glucose metabolism (insulin resistance [IR]), inflammation and BMI in adolescents with obesity and IR, and to assess the relationship between therapeutic intervention(s) and changes in gut microbiome composition and function. Since MET and FIBER have been shown to reduce weight and increase insulin sensitivity through distinct but overlapping mechanisms of action, our central hypothesis is that the combination of FIBER + MET will have a synergistic effect and be more effective than FIBER or MET alone in improving metabolic function (IR) and reducing BMI and inflammation in adolescents with obesity, IR and family history (FM) of T2DM. .
Familial Partial Lipodystrophy type 2 (FPLD2) is a heterogeneous group of rare lipodystrophy due to autosomal dominant mutation in LMNA encoding Lamin A/C. Lamins A and C form with the B-type lamins the lamina network underlying the nuclear envelope. Lamins are major components that provide structural and mechanical stability for the nucleus ubiquitously. Lamins are also key epigenetic regulator. Mutations in LMNA are involved in different inherited pathologies as Emery-Dreifuss muscular Dystrophy, Limb Girdle muscular dystrophy, dilated cardiomyopathy and conduction system disease, Charcot Marie Tooth Disorder type 2, mandibuloacral dysplasia, Hutchinson Gilford progeria and Dunnigan-type-familial partial lipodystrophy (FPLD2). Inherited lipodystrophy prevalence is reported around 1.3 to 10 cases per million worldwide and FPLD2 is the most frequent of all. Nevertheless, recent reports with systematic screening in all non-obese patients with type 2 diabetes or metabolic syndrome found higher prevalence of lipodystrophy up to 1/7000 subjects. FPLD2 remain a rare group of disease and only relatively small and heterogeneous cohorts of patients are reported. For this reason it is difficult to fully decipher all aspects of this rare group of diseases. The "typical" FPLD2 is associated with missense mutation affecting the arginin residue in position 482 (p.R482Q,p.R482W,p.R482L). Patients harbouring mutation in other spot are considered to have "atypical" lipodystrophy. The "typical" FPLD2 start around puberty with progressive subcutaneous fat loss in upper limbs, gluteo-femoral adipose tissue and trunk and fat accumulation in the cervicofacial area, neck, upper trunk, labia majora and visceral fat. Resulting from the inability to store fat, patients affected by inherited lipodystrophy develop severe metabolic syndrome and its complications: type 2 diabetes (DT2), dyslipidaemia, nonalcoholic fatty liver disease (NAFLD) and premature cardiovascular disease (CVD). In 2006 a specific mutation of LMNA has been described in a patient originated from La Réunion living in France mainland. To date this mutation have only been reported in patient native from La Réunion and is called 'Reunionese' mutation and consist in a G insertion after nucleotide 5670 (codon 654) in the prelamin-A-specific exon 11 (g.5670_5671insG) p.T655fsX49 that lead to a longer and non farnelysated prelamin A lacking the C-terminal CSIM motif. As a result, nonfarnelysated mutated prelamin A accumulated in the cells leading to oxidative stress and premature cell senescence. The 'Reunionese' mutation is expressed in 2 forms either homozygous or heterozygous. Homozygous patients present with more severe phenotype and cardiac laminopathy. The aim of our study is to update the characterization of the patients diagnosed with the 'Reunionese' mutation. The investigators report here the largest cohort of patient with FPLD2 due to one single LMNA mutation either homozygous or heterozygous.
The purpose of this prospective randomized controlled study is to evaluate the impact of a six-month digitally administered behavioral change program on body weight, glycemic control and other metabolic parameters in obese adults with insulin resistance, prediabetes or type 2 diabetes as compared to conventional high-intensity lifestyle intervention program administered at a specialized department of a university hospital.
