Stolic RV, et al. - Researchers determined the factors (including relevant clinical and laboratory parameters) that might impact the function of arteriovenous fistulas (AVFs), which are the preferred form vascular access for hemodialysis (HD). They analyzed 2-year data obtained from the computerized patient record system in the Clinic of Urology and Nephrology, Clinical Center, Kragujevac, Serbia, and examined patients who had requested re-creation of AVFs as a secondary procedure. They found that maintenance of fistula patency was a compelling need following successful establishment of an AVF. Magnesium, triglycerides, smoking, antiplatelet therapy, and type of HD (bicarbonate vs hemodiafiltration) were identified as the statistically significant predictors impacting the duration of the fistula, as observed in the univariate logistic regression analysis. A significant association of high concentrations of magnesium and antiplatelet therapy with the length of AVF function was revealed in the multiple logistic regression model.
