Insulin Resistance and Vessel Function After Meals: Does Early Intervention Make a Difference?
Insulin ResistanceImpaired Fasting GlucoseThe purpose of this study is to determine whether attenuation/normalization of elevated blood sugar after meals ameliorates vessel wall (endothelial) function in individuals with insulin resistance.
Insulin Signaling in Skeletal Muscle
Insulin SensitivityThe insulin sensitizing effects of metformin and pioglitazone in the skeletal muscle remain unknown. Our group aims to analyze molecular changes within the skeletal muscle of pre-diabetic patients through the use of a clinical trial in humans.
Diabetes Prevention Program (METFIT) in Reducing Insulin Resistance in Stage I-III Breast Cancer...
Anatomic Stage I Breast Cancer AJCC v8Anatomic Stage IA Breast Cancer AJCC v819 moreThis trial studies how well a diabetes prevention program (METFIT) works in reducing insulin resistance in stage I-III breast cancer survivors. METFIT program, a diet and lifestyle intervention, utilizes intermittent fasting to reduce insulin resistance in insulin resistant breast cancer survivors. Intermittent fasting has been shown to have benefits for patients undergoing cancer therapy by improving symptoms such as fatigue in breast cancer patients. Intermittent fasting has also shown potential for decreasing the risk of breast cancer coming back (recurrence). This trial is being done to determine if METFIT program can be successfully and effectively implemented to reduce insulin resistant in breast cancer survivors.

Insulin ResistanceEndothelial DysfunctionThe hypothesis is that GHRP-3 will exert beneficial effects on endothelial function and insulin resistance in older men and women via hormonal (GH, IGF-I, IGFBP-3,-1, insulin) and non-hormonal actions (anti-inflammatory).
Effect of GLP-1 on Microvascular Insulin Responses in Type 1 Diabetes
Type 1 DiabetesInsulin Sensitivity/ResistanceGLP-1 increases skeletal and cardiac microvascular perfusion and improves insulin's microvascular responses in human subjects with T1DM, leading to improved metabolic insulin responses, endothelial function, and increased muscle oxygenation
Effect of Neuromuscular Electrostimulation on Sympathetic Nerve Activity in Patients With Type 2...
Type 2 DiabetesInsulin ResistancePhysical activity (PA) is recommended for the treatment of subjects with type 2 diabetes to increase insulin sensitivity and improve metabolic control. However, adherence to PA is often poor, due to a lack of motivation or due to disabling complications or comorbidities. Neuromuscular electrostimulation (NMES) is a physical treatment commonly used to improve muscle strength and volume in several situations: after stroke, after limb trauma or during chest rehabilitation in deconditioned patients. The investigators have already shown in a first pilot study (manuscript in preparation) that NMES improves insulin sensitivity : in the study ELECTRODIAB (No. ID-RCB: 2011-A00930-41), the investigators showed a 25% insulin sensitivity improvement after a week of daily 25-min bi-quadricipital NMES session, in a population of patients with orally-treated type 2 diabetes. Insulin sensitivity increased up to 50% in the most deconditioned subjects. Discrepancy between this result and the very low energy expenditure measured during sessions suggests that the metabolic effect was not solely mediated by muscle contractions. The investigators hypothesize the involvement of neurological pathways. Indeed, it is demonstrated that the autonomic nervous system is an important regulator of glucose metabolism with pancreatic action, a key role in energy metabolism and a complex relationship with insulin resistance. Muscle activity, whether static (isometric) or dynamic causes changes in sympathetic nerve activity in healthy subjects but its effect in type 2 diabetic subjects is not known. The investigators hypothesize that, in type 2 diabetic subjects, the modulation of sympathetic nerve activity by NMES could be involved in the improvement of insulin sensitivity. To address this question, the investigators propose to assess sympathetic nerve activity with the gold standard method of microneurography before and after a single bi-quadricipital NMES session. The impact of neuro-electro-stimulation (NES) (a sensitive stimulation under muscular threshold) and the impact of voluntary isometric muscle contractions (VC) will also be evaluated. These procedures will also be applied in healthy control subjects.

Effect of Levothyroxine on Serum Adiponectin, Insulin Resistance and Cardiovascular Risk in Patients...
HypothyroidismThe aim of this study is to evaluate plasma adiponectin level, insulin resistance, cardiovascular risk and their correlation (if any) in patients with hypothyroidism and also to investigate the effect of levothyroxine on these parameters. The study may explore the lacunae in present treatment protocol and can suggest the possibilities of add-on therapies for a better management.
