In a preliminary study of the ejaculate of 93 men, changes in motility and hypo-osmotic swelling before and after sperm separation by discontinuous Percoll gradients were evaluated. Both parameters improved significantly (P less than 0.01) in Percoll-separated spermatozoa. In a second stage, 99 couples underwent intrauterine insemination of separated semen(More)
BACKGROUND This study aims to describe the healthcare resource utilization and costs of managing renal posttransplant patients over 3 years posttransplant in nine European countries and to stratify them by year 1 glomerular filtration rate (GFR). METHODS A retrospective observational and database analysis of renal transplant patients and a physician(More)
A prospective study on hypotension in hemodialysis was performed in 60 nondiabetic patients at two different dialysate temperatures during 12 months. A 37 degrees C bath (3,723 sessions) was used and after the first 6 months the temperature was changed to 35 degrees C (4,019 sessions). The prevalence of symptomatic hypotension was 15.3% and it was closely(More)
A high prevalence of hypercalciuria has been reported in patients with essential hypertension. Nevertheless, the clinical and therapeutic implications of this finding have scarcely been studied. This study was designed to determine the prevalence of hypercalciuria in an unselected population with essential hypertension and to analyze the relationship(More)
AIMS To study the effect of flap thickness on the visual and refractive outcome of myopic laser in situkeratomileusis (LASIK) surgery. METHODS A total of 196 myopic eyes with spherical equivalent (SE) from -2.00 to -5.00 dioptres which underwent LASIK were studied retrospectively. Uncorrected visual acuity (UCVA), best-corrected visual acuity (BCVA) and(More)
The contributions of membrane biocompatibility, dialysate temperature and sodium concentration to hemodynamic stability during hemodialysis were studied in 8 patients with a high incidence of hemodialysis-induced symptomatic hypotension. Patients were treated during 8 different periods, randomly ordered in each case, resulting from the combination of the(More)
In order to ascertain whether there are abnormalities of nonenzymatic glycosylation in uremia, the levels of nonenzymatically glycosylated hemoglobin (GHb), and total plasmatic glycosylated proteins (PGP) were studied using the thiobarbituric acid (TBA) method, a procedure not interfered with by carbamylation. Total hemoglobin A1 (HbA1) and the A1c fraction(More)
The prevalence of hyperuricemia was investigated in 214 kidney allograft recipients, 81 were on azathioprine and steroids and 133 on cyclosprine (CyA) and low-dose steroids or on triple therapy. All had stable renal function, serum creatinine < 2.5 mg/dl, and a follow-up between 12 and 120 months. At the time of the study, blood and urine samples were(More)
Incidence of intradialytic symptomatic hypotension was significantly reduced by lowering dialysate temperature from 37 degrees C to 35 degrees C. This improvement seems not to be mediated by temperature-induced changes in membrane biocompatibility, since leukocytes, platelets and complement activation were similar in both situations.
ABSTRACT The aim of this study was to compare the accuracy of three kidney function estimating equations: classic Cockcroft-Gault (classic CG), corrected Cockcroft-Gault (corrected CG) and simplified Modification of Diet in Renal Disease (MDRD), in patients with advanced chronic renal failure. The study was made in 84 nondialyzed patients with chronic renal(More)
