Soluble urokinase receptor is a biomarker of cardiovascular disease in chronic kidney disease.

Soluble urokinase-type plasminogen activator receptor (suPAR) accumulates in patients with chronic kidney disease (CKD). In various non-CKD populations, suPAR has been proposed as a prognostic marker for mortality and cardiovascular disease. However, it is not known whether suPAR holds prognostic information in patients with mild-to-moderate CKD.

The soluble urokinase receptor is not a clinical marker for focal segmental glomerulosclerosis.

The soluble urokinase receptor (suPAR) promotes proteinuria and induces focal segmental glomerulosclerosis (FSGS)-like lesions in mice. A serum suPAR concentration cutoff of 3000 pg/ml has been proposed as a clinical biomarker for patients with FSGS. Interestingly, several studies in patients with glomerulopathy found an inverse correlation between the estimated glomerular filtration rate (eGFR) and suPAR.

Can we improve the positive predictive value of atypical glandular cells not otherwise specified?

The category of atypical glandular cells (AGC) in gynecologic cytopathology presents many well-documented diagnostic challenges, the most significant related to high interobserver variability, low specificity, and low positive predictive value. The current Bethesda System provides criteria for specific glandular categories including atypical endocervical cells not otherwise specified (AEC-NOS), AEC favor neoplastic, and atypical endometrial cells. The Bethesda System does, however, acknowledge that in some cases AGC cannot be categorized based upon cell of origin, in which case the generic term "atypical glandular cells" (AGC) may be used.

Real-time PCR as a new in vitro biocompatibility method to measure leukocyte response to surface contact in dialysis filter devices.

Introduction: The mortality risk of dialysis patients is still elevated. Even though there is continuous improvement in the biocompatibility of dialysis devices and treatments, there is clinical evidence of a negative inflammatory impact. One dialysis-related risk factor to be considered in this regard may be the repeated blood exposure to foreign filter surfaces.

The role of polymer surface degradation and barium sulphate release in the pathogenesis of catheter-related infection.

Background: Susceptibility to infection and thrombosis of intravascular catheters is increased by surface irregularities, which might be prevented by coating.

Methods: BaSO4 release from conventional haemodialysis catheters (CC) and modified catheters (MC) which had been coated with a surface-modifying additive (SMA) was assessed in vivo and in vitro. For the in vivo part, patients were randomized to receive a temporary CC or MC, with crossover after 1 week.

The role of deeper levels and ancillary studies (p16(Ink4a) and ProExC) in reducing the discordance rate of Papanicolaou findings of high-grade squamous intraepithelial lesion and follow-up cervical biopsies.

Background: Discordant results of cervical biopsy histology after a cytologic diagnosis of high-grade squamous intraepithelial lesion (HSIL) are often attributed to sampling variation. The purpose of the current study was to determine whether deeper levels and ancillary staining (p16(Ink4a) and ProExC) reduce the discordant rate.

Methods: A total of 246 cases of HSIL were retrieved from the computerized database from 2005 and 2006.

Validity of sampling error as a cause of noncorrelation.

Background: Sampling error is a common explanation of noncorrelation in women whose Papanicolaou (Pap) tests show high-grade intraepithelial lesions (HSIL) but whose follow-up cervical biopsies show only cervical intraepithelial neoplasia (CIN) 1, koilocytosis, or reactive/inflammatory changes. The purpose of this study was to demonstrate the validity of sampling error in this setting by determining the proportion of negative colposcopic cervical biopsies in women with HSIL who subsequently undergo cone/loop electrode excision procedure (LEEP) biopsies or repeat cervical biopsies that confirm the diagnosis of high-grade CIN (HGCIN).

Methods: In all, 368 cases of HSIL were retrieved from the computerized database from January 1, 2003 to December 31, 2005.

Prolonged catheter survival in intermittent hemodialysis using a less thrombogenic micropatterned polymer modification.

Adequate vascular access is a major prerequisite for hemodialysis treatment. Catheter related complications, in particular thrombus formation, are frequent, difficult to handle, and cost intensive. We investigated whether a new surface modified catheter containing a microdomain structure is beneficial for catheter survival.
