Objective. Febrile urinary tract infection (UTI) is a common problem among children. The diagnosis and management of acute pyelonephritis is a challenge, particularly during infancy. The distinction between acute pyelonephritis and UTI without renal involvement is very important, because renal infection may cause parenchymal scarring and thus requires more aggressive investigation and follow-up monitoring. However, this distinction is not easy among children, because common clinical findings and laboratory parameters are nonspecific, especially among young children. In an attempt to differentiate acute pyelonephritis from febrile UTI without renal lesions in a group of 100 children, we measured serum levels of procalcitonin (PCT), a new marker of infection. The objective of the study was to determine the accuracy of PCT measurements, compared with C-reactive protein (CRP) measurements, in diagnosing acute renal involvement during febrile UTI and in predicting subsequent scars, as assessed with ^99mTc-dimercaptosuccinic acid (DMSA) scintigraphy. Design. Serum CRP levels, erythrocyte sedimentation rates, leukocyte counts, and PCT levels were measured for 100 children, 1 month to 13 years of age, admitted for suspected febrile UTI (first episode). Renal parenchymal involvement was evaluated with DMSA scintigraphy within 5 days after admission. The DMSA study was repeated 6 months later if the initial results were abnormal. Results. The mean PCT level was significantly higher in acute pyelonephritis than in UTI without renal lesions (4.48 ± 5.84 ng/mL vs 0.44 ± 0.30 ng/mL). In these 2 groups, the mean CRP levels were 106 ± 68.8 mg/L and 36.4 ± 26 mg/L, mean erythrocyte sedimentation rates were 79.1 ± 33 mm/hour and 58.5 ± 33 mm/hour, and leukocyte counts were 18 492 ± 6839 cells/mm³ and 16 741 ± 5302 cells/mm³, respectively. For the prediction of acute pyelonephritis, the sensitivity and specificity of PCT measurements were 83.3% and 93.6%, respectively; CRP measurements had a sensitivity of 94.4% but a specificity of only 31.9%. Positive and negative predictive values for prediction of renal involvement with PCT measurements were 93.7% and 83% and those with CRP measurements were 61.4% and 83.3%, respectively. When inflammatory markers were correlated with the severity of the renal lesions, as assessed with DMSA scintigraphy, a highly significant correlation with both PCT and CRP levels was found. However, when the 2 parameters were correlated with renal scarring in follow-up scans, a significant positive association was found only for PCT levels. Conclusions. Serum PCT levels may be a sensitive and specific measure for early diagnosis of acute pyelonephritis and determination of the severity of renal parenchymal involvement. Therefore, this measurement could be useful for the treatment of children with febrile UTIs, allowing prediction of patients at risk of permanent parenchymal renal lesions.

Sustainable Development Goals (SDGs) and 2030 Agenda represent global development programs. Education can widen the acknowledgement of their relevance and their applications. This survey aims to assess awareness, knowledge and attitudes towards SDGs and sustainability among first-year students in nine Italian Universities. A Likert scale-based online questionnaire of 70 items was compiled by students from March to July 2019. It examined knowledge and expectations referred to sustainable development concepts, indicators and documents/models accounting for sociodemographic variables. Statistical analyses performed were Chi-square test, Fisher’s Exact test, Kendall’s W correlation coefficient, univariate and multivariate analysis. The questionnaire was completed by 1676 students. A low percentage referred a good knowledge of SDGs and 2030 Agenda, most of them had never attended related educational activities previously. Better knowledge of SDGs and 2030 Agenda was observed in case of previous specific educational activities (p < 0.001). The expectation towards university guaranteeing an education on SDGs was high, both for personal wisdom and for usefulness in future professional context. A significant difference (p < 0.001) in such expectations was found, as healthcare students were less interested than colleagues of other areas. The results showed low knowledge but interest towards sustainable development. A scheduled implementation of academic initiatives should be considered.
