Background: Acute pyelonephritis is a severe disease which is sometimes difficult to recognize based on clinical symptoms and routinely available diagnostic tests, especially in young children. The aim of this study was to assess the diagnostic value of urinary neutrophil gelatinase-associated lipocalin (uNGAL) as a biomarker of acute pyelonephritis. Methods: In this case-control study we analyzed 134 children (median age 2.5 years) who were admitted to the Pediatric Clinic of University Hospital Centre Osijek, Croatia. Eighty of them had acute pyelonephritis, while 54 children had febrile state of different etiology including cystitis and they represented the control group. uNGAL, white blood cells, C-reactive protein, urinanalysis, urine culture, kidney ultrasound and a dimercaptosuccinic acid scintigraphic scan were done for each child. uNGAL was measured using chemiluminiscent microparticle immunoassay on ARHITECT i1000SR (Abbott Diagnostics, IL, USA). Results: uNGAL values were significantly higher in children with acute pyelonephritis compared to the control groups (113.6 ng/mL vs. 10.2 ng/mL, p<0.001). A receiver operating characteristic curve comparison was done for tested parameters and encouraging results were obtained for uNGAL (AUC=0.952). A cut-off value of 29.4 ng/mL had 92.5% sensitivity and 90.7% specificity. We showed that uNGAL can also serve in differentiating acute pyelonephritis from cystitis (cut-off 38.5 ng/mL), and for differentiation of cystitis from febrile states with etiology other than urinary tract infection (UTI) (cut-off 20.4 ng/mL). Conclusions: uNGAL can be a useful diagnostic biomarker in acute pyelonephritis in children, but also in differentiating cystitis from febrile states other than UTI. © 2016 by De Gruyter 2016.

Aims: The British National Diet and Nutrition 2000/1 Survey data set records on 1,724 respondents (766 males and 958 females) were analyzed in order to assess the potential influences of red and processed meat intakes on cardiovascular risk factors. Methods: Linear regression of the associations of the red, processed, combination of red and processed, and total meat intakes with body mass index (BMI), systolic blood pressure and plasma total cholesterol as cardiovascular risk factors was conducted, paying due attention to the subject age and sex as potential confounders. Results: Linear analyses showed the total meat intake and combined red and processed meat intake to cause a 1.03 kg/m2 rise in BMI each, while the red and processed meat intakes analyzed as separate categories caused 1.02 kg/m2 rise each. The greatest effects were observed on the systolic blood pressure with a 1.7 mm Hg rise for the total and the red and processed meat intakes, 1.5 mm Hg rise for the red meat intake, and 1.02 mm Hg rise for the processed meat intake. There were no associations between different meat intakes and plasma total cholesterol. Discussion and Conclusion: Study results revealed the interquartile ranges of the mentioned meat type intakes to increase BMI by around 1 kg/m 2 and systolic blood pressure by around 1.5 mm Hg, while they had no influence on plasma total cholesterol.
