INTRODUCTION The aim of this study was to determine whether the degree of fluid responsiveness in critically ill septic patients is related to baseline mixed venous oxygen saturation (SvO2) levels. We also sought to define whether fluid responsiveness would be less likely in the presence of a high SvO2 (>70%). METHODS This observational study was conducted in a 32-bed university hospital medi...

OBJECTIVE Evaluate male patients with diagnosed chronic prostatitis, elevated serum prostate-specific antigen (PSA) to find out whether medical treatment with antibiotics and anti-inflammatory drugs can lower serum PSA, and consequently decrease the prostate cancer detection rate in patients with post-treatment PSA<4 ng/mL. MATERIALS AND METHODS This prospective study evaluated 142 male patie...

BACKGROUND AND PURPOSE The Carotid Revascularization Endarterectomy Versus Stenting Trial was completed with a low stroke and death rate. A lead-in series of patients receiving carotid artery stenting was used to select the physician-operators for the study, where performance was evaluated by complication rates and by peer review of cases. Herein, we assess the potential contribution of statist...

We investigated the pattern of inheritance of maternal meiotic errors responsible for a high frequency of triploid progeny in a selected line of chickens. For the genetic analysis, F1 and backcross populations were produced from crosses between normal diploid individuals of the triploidy line and a control line. Triploid embryos were produced by 35% and 67% of reciprocal F1 females and by 24% a...
