Although ultrasonography (US) remains the most widely used diagnostic imaging modality for routine evaluation of the fetus, magnetic resonance (MR) imaging has become an invaluable complement to US in all cases in which additional information is desirable. While the ability of US to detect fetal abnormalities is limited in cases such as maternal obesity,(More)
The aim of this study was to assess infectious complications in transrectal ultrasound-guided prostate biopsy (TRUSPB), comparing two groups of patients: one group with antibiotic prophylaxis and the other without prophylaxis. A total of 1,018 TRUSPBs were performed from April 1996 to July 2003. No antibiotic prophylaxis was given in the first 614; the(More)
Exercises after arteriovenous fistula (AVF) creation may help to improve maturation; however, their usefulness has only been examined in indirect, non-comparative studies or small trials. Between June 2013 and November 2014, we included all ambulatory patients with stages 5-5D chronic kidney disease who were candidates for the creation of a native AVF in(More)
In Portugal, due to the combination of climatological and ecological factors, large wildfires are a constant threat and due to their economic impact, a big policy issue. In order to organize efficient fire fighting capacity and resource management, correct quantification of the risk of large wildfires are needed. In this paper, we quantify the regional risk(More)
PURPOSE Access blood flow (Qa) measurements are one of the most important components in vascular access monitoring programs, even though these indirect methods have only been validated with high-flux hemodialysis (HF; pump flow [Qb] 300 mL/min). This study was to assess the utility from thermodilution (BTM) with respect to the saline dilution method (SDM)(More)
• This work overviews some developments on the estimation of the Receiver Operating Characteristic (ROC) curve. Estimation methods in this area are constantly being developed, adjusted and extended, and it is thus impossible to cover all topics and areas of application in a single paper. Here, we focus on some frequentist and Bayesian methods which have(More)

PURPOSE To describe radiologic findings, embolization technique, and clinical outcomes in patients with renal subcapsular hematoma and diffuse cortical hemorrhage. MATERIALS AND METHODS Ten patients with renal subcapsular hematoma and diffuse cortical hemorrhage were reviewed. Nine of the 10 had undergone procedures (nephrostomy, n = 4; biopsy, n = 4;(More)
To evaluate the efficacy and safety of the hydrodynamic thrombectomy catheter (AngioJet DVX) in the salvage of thrombosed hemodialysis vascular grafts. A retrospective study was designed, including all patients with occluded arteriovenous grafts treated with the AngioJet system between 2007 and 2014 in our institution. Outcomes included technical success,(More)
