This study evaluates differences in brain function and cognitive performance in adolescents with type 2 diabetes (T2D) compared to non diabetic controls (both obese and lean) and correlates these changes with obesity, insulin resistance, and glycemic control in youth with T2D.
Nine healthy, moderately fit male volunteers participated in the study. The subjects gave written informed consent after having been informed of any possible risk and discomfort associated with the study. The study was approved by the regional ethics committee in Denmark (Journal number: H-4-2013-071) and performed in accordance with the Declarations of Helsinki II. All subjects underwent 3 clinical investigations (day 1, day 2 and day 5) during a 5 day glycogen supercompensation regime. The subjects were asked to refrain from physical activity and to eat a controlled diet containing 60% carbohydrates (CHO) for 4 days prior to the initial experiments. Upon arrival at the laboratory on day 1, the subjects performed one-legged knee extensor exercise for 1 hour at 80% of PWL interspersed by 5 min bouts at 90% of PWL. This was followed by interval exercise until exhaustion containing 4 min bouts starting at 100% PWL followed by 1 min at 50% of PWL. Upon cessation of exercise the subjects showered and rested in the supine position for 4 hours. Then a 120 min hyperinsulinemic euglycemic clamp was initiated by a bolus insulin injection (9.0 mU/kg, Actrapid, Novo Nordisk, Denmark) followed by continuous insulin infusion (1.42 mU/kg/min insulin) reaching a level of plasma insulin around 100 µU/mL (n=9). At least 2 hours before the insulin clamp, catheters were placed in both femoral, one antecubital and one dorsal hand vein. A heat pad was placed around the lower part of the arm and hand in order to "arterialize" blood drawn from the hand vein. Substrate uptake/release across the legs was calculated by multiplying the arterial-venous (AV) difference in blood substrate concentration by femoral arterial blood flow (measured by ultrasound, Philips DICOM). Blood glucose levels were maintained at the euglycemic predefined target by continuously adjusting the glucose infusion rate (GIR) (20% glucose solution; Fresenius Kabi, Sweden). Concurrent measures of substrate AV differences and blood flow were performed every 20 min. Muscle biopsies from m. vastus lateralis were obtained under local anaesthesia (3-5 ml of Xylocaine, 20 mg/ml.) in the basal- and insulin-stimulated state (120 min) by use of needle biopsy technique. Muscle specimen were frozen within 20 sec in liquid nitrogen and stored at -80°C for further analysis. A new incision was made for every biopsy and spaced 4-5 cm apart. This insulin clamp procedure in combination with basal and insulin stimulated muscle biopsies was repeated in the rested state (without prior exercise) on day 2 and day 5. The subjects arrived in the morning in the overnight fasted state at day 1, day 2 and day 5. During the 5 day supercompensation regime the subjects were provided a predefined isocaloric diet containing 80% carbohydrates, 10% fat and 10% proteins. All food items were handle out to the subjects and compliance of the diet regime was ensured by survey.
The 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.
We investigate the association between Triglyserid-Glucose(TyG) index and prostate cancer in patients undergoing radical prostatectomy.
It will be evaluated whether carnitine, a dietary supplement, reduces liver fat and improves metabolism in individuals who have a high concentration of fat within their liver. Participants will be given either Carnitine or placebo, together with a meal replacement milkshake twice daily for 6 months.
The objective of this study is to investigate the effect ofRutin and Vitamin C combination in comparison with vitamin C alone on the oxidative and antioxidative status , insulin resistance and lipid profile in type 2 diabetic patients.
Probiotics have beneficial effect on obesity related disorders in animal models. Despite a large number of animal data, randomized placebo-controlled trials (RCT) concluded that probiotics have a moderate effect on glycemic control-related parameters. However, effect of probiotics on insulin resistance are inconsistent. In this double-blind single center RCT, effect of alive multistrain probiotic vs. placebo on insulin resistance in type 2 diabetes patient will be assessed.
A quantitative prospective cohort study will be conducted, where blood samples will be collected at different timings during the IVF protocol, to assess the impact of fertility medications on metabolic parameters of patients undergoing IVF treatment.
The main purpose of this study is to study the phenomenon of insulin resistance in patients after carotid revascularization surgery through population-based, randomized, double-blind, placebo-controlled trial.
