Chronic kidney disease (CKD) is associated with increased cardiovascular events. The relationships between the markers of inflammation and endothelial dysfunction were investigated both before and after living donor kidney transplantation.', 'Twenty-seven renal transplant patients were studied. Eleven patients (six male, five female) were on cyclosporine A, whereas 16 patients (nine male, seven female) were treated with tacrolimus based regimes. Twenty-seven subjects (12 males, 15 females) were studied as controls. Plasma adiponectin, high sensitive C reactive protein (hsCRP), Asymetric dimethyl arginine (ADMA) levels were studied before transplantation and on days 1, 3, 7, 14, and 28. The brachial artery flow mediated dilatation (FMD) was studied before transplantation and on the 28th day.', 'Serum hsCRP and ADMA levels decreased significantly from the first posttransplantation day on each measurement (P<0.001 for all) while the decrement of plasma adiponectin started in the third day (P<0.001 for all). The FMD was lower in the patients than the control group (P<0.001) and improved significantly in the 28th day of transplantation (P<0.001).
Do endothelial functions improve with decrease in asymmetric dimethylarginine ( ADMA ) levels after renal transplantation?

This study investigated the isolated and combined effects of heat [temperate (22\xa0°C/30\xa0% rH) vs. hot (35\xa0°C/40\xa0% rH)] and hypoxia [sea level (FiO2 0.21) vs. moderate altitude (FiO2 0.15)] on exercise capacity and neuromuscular fatigue characteristics.', 'Eleven physically active subjects cycled to exhaustion at constant workload (66\xa0% of the power output associated with their maximal oxygen uptake in temperate conditions) in four different environmental conditions [temperate/sea level (control), hot/sea level (hot), temperate/moderate altitude (hypoxia) and hot/moderate altitude (hot\xa0+\xa0hypoxia)]. Torque and electromyography (EMG) responses following electrical stimulation of the tibial nerve (plantar-flexion; soleus) were recorded before and 5\xa0min after exercise.', 'Time to exhaustion was reduced (P\xa0<\xa00.05) in hot (-35\xa0±\xa015\xa0%) or hypoxia (-36\xa0±\xa014\xa0%) compared to control (61\xa0±\xa028\xa0min), while hot\xa0+\xa0hypoxia (-51\xa0±\xa020\xa0%) further compromised exercise capacity (P\xa0<\xa00.05). However, the effect of temperature or altitude on end-exercise core temperature (P\xa0=\xa00.089 and P\xa0=\xa00.070, respectively) and rating of perceived exertion (P\xa0>\xa00.05) did not reach significance. Maximal voluntary contraction torque, voluntary activation (twitch interpolation) and peak twitch torque decreased from pre- to post-exercise (-9\xa0±\xa01, -4\xa0±\xa01 and -6\xa0±\xa01\xa0% all trials compounded, respectively; P\xa0<\xa00.05), with no effect of the temperature or altitude. M-wave amplitude and root mean square activity were reduced (P\xa0<\xa00.05) in hot compared to temperate conditions, while normalized maximal EMG activity did not change. Altitude had no effect on any measured parameters.
Does combining heat stress and moderate hypoxia reduce cycling time to exhaustion without modifying neuromuscular fatigue characteristics?

To examine the correlation between transcranial Doppler ultrasonography-detected emboli during coronary artery bypass graft surgery with cardiopulmonary bypass and renal dysfunction as determined by the postoperative change in creatinine.', 'Retrospective review of data from the anesthesia and cardiothoracic surgery databases.', 'Tertiary care university hospital.', 'Two hundred eighty-six patients undergoing coronary artery bypass graft surgery.', 'Transcranial Doppler ultrasonography of the right middle cerebral artery was performed after induction of general anesthesia through completion of the operation. Doppler signals were recorded and emboli counts determined using an automated counting system.', 'Renal dysfunction was assessed as the change in creatinine from the preoperative value to the maximum postoperative value (Delta-Cr). There was a significant (p = 0.0003) univariate correlation between postoperative change in creatinine and total number of Doppler-detected emboli. The effect of total number of emboli remained significant (p = 0.0038) in the multivariable analysis after adjustment for covariables (age, sex, number of grafts, left ventricular ejection fraction, hypertension, history of congestive heart failure, diabetes, cardiopulmonary bypass time, preoperative creatinine, and maximum postoperative creatinine).

Do transcranial Doppler emboli count predicts rise in creatinine after coronary artery bypass graft surgery?
