Question: Context: To examine the effect of short-term improvements in glycaemic control on brachial artery endothelial function as a marker of cardiovascular health.', 'Persons with Type 2 diabetes who were poorly controlled on oral therapy were randomly assigned to monotherapy with repaglinide or combination therapy with repaglinide plus metformin. Brachial artery flow-mediated vasodilation was assessed by ultrasonography at randomization and following 16 weeks of therapy. The primary outcome was change in brachial artery endothelial function from baseline. Comparison of randomized groups was a secondary aim.', 'Eighty-six participants were randomized, and 83 were followed to study completion. Post occlusion brachial artery vasodilation was 3.74% at baseline and 3.82% following 16 weeks of therapy (P = 0.77). The treatment effect was 0.08% (95% CI: -0.48%, 0.64%). No difference was seen between treatment groups (P = 0.69). Overall, A1C was reduced from 8.3% to 7.0%, with a greater reduction in the combination therapy group (from 8.4% to 6.7%) than in the monotherapy group (from 8.3% to 7.3%, p for difference between groups = 0.01). Statistically significant reductions were observed in fasting glucose, and plasminogen activator inhibitor-1. Statistically significant increases were observed for fasting insulin, uric acid, weight and BMI.\Question: Does the combination oral and nutritional treatment of late-onset diabetes mellitus ( CONTROL DM ) trial result?

Answer: Brachial artery endothelial function was not influenced by short-term improvements in glycaemic control. The CONTROL DM group was successful in lowering A1C. Future research should explore more intensive and longer-lasting improvements in glycaemic control on endothelial function. Some data previously published in abstract form (Diabetes 2001; 50 (Suppl. 2): A217).

Question: Context: To test device integrity and objective auditory reaction for cochlear implant patients intraoperatively.', 'Our protocol for intraoperative testing of the implant device includes device electrode impedance test and neural response telemetry (NRT), which measures the electrically evoked auditory nerve compound action potentials (ECAP).', 'We completed electrode integrity tests and NRT intraoperatively on 40 patients with the Nucleus CI24M cochlear implant. We have measured normal implant function on all 40 patients and obtained ECAP results from 39 patients. Out of 33 patients with normal inner ear, typical ECAPs were recorded in 195 electrodes in all 198 testing electrodes(98.5%). In 7 patients with inner ear Mondini dysphasia, affirmative ECAP waveforms were recorded in 26 electrodes in all 42 testing electrodes. The basal electrode ECAP threshold was higher than that of the epical one.\Question: Do [ The intraoperative application of neural response telemetry with the nucleus CI24M cochlear implant ]?

Answer: The intraoperative measurements of device function and NRT are quite simple, quick and with high accuracy. Inner ear malformation is an important factor that may affect NRT results.

Question: Context: In recent years acute rejection has decreased to 10% to 20%. Therefore it is necessary to look for new endpoints in renal transplantation. Serum creatinine and changes in creatinine have been reported to be powerful predictors of long-term kidney transplant survival. Chronic renal allograft nephropathy is the primary cause of long-term graft failure but may appear at any stage in the evolution.', 'Data from 315 patients receiving cadaver donor renal transplants between February 1987 and March 2001 that functioned for 1 year were examined for the influence of demographic characteristics and transplant variables. Creatinine clearance was estimated using the Cockroft-Gault formula. Survival was assessed with the actuarial method. The multivariate analyses were performed using Cox proportional hazard models.', 'The 10-year graft survival showed a relative risk of 2.5 in the univariate analysis when there was more than 10% decrease in renal function at 3 months compared with nadir values. When the decrease was more than 25% of creatinine clearance at the third month, during the evolution and serum creatinine at 3 months introduced in the multivariate model, the latter was not significant, while the other variables had a RR of 4.4 and 10, respectively.\Question: Is evolution of the renal function a better predictor of long-term survival than serum creatinine?

Answer:
The evolution of renal function at 3 months and throughout the evolution were better predictors of graft failure than an isolated serum creatinine value.
