RESUMO

Rising rates of antibiotic resistance in uropathogenic bacteria compromise patient outcomes and prolong hospital stays. Consequently, new strategies are needed to prevent and control the spread of antibiotic resistance in uropathogenic bacteria. Over the past two decades, sizeable clinical efforts and research advances have changed urinary tract infection (UTI) treatment and prevention strategies to conserve antibiotic use. The emergence of antimicrobial stewardship, policies from national societies, and the development of new antimicrobials have shaped modern UTI practices. Future UTI management practices could be driven by the evolution of antimicrobial stewardship, improved and readily available diagnostics, and an improved understanding of how the microbiome affects UTI. Forthcoming UTI treatment and prevention strategies could employ novel bactericidal compounds, combinations of new and classic antimicrobials that enhance bacterial killing, medications that prevent bacterial attachment to uroepithelial cells, repurposing drugs, and vaccines to curtail the rising rates of antibiotic resistance in uropathogenic bacteria and improve outcomes in people with UTI.

RESUMO

Urinary tract infections (UTIs) are a common comorbidity in hospitalized neonates. The current UTI diagnostics have several limitations including invasive collection of urinary samples to ensure sterility, risk of contamination and lack of consensus definitions of UTI based on urine culture. Antimicrobial peptides (AMPs) have been recently utilized as novel biomarkers that can efficiently and accurately diagnose pediatric UTI. However, the concentration of AMPs in neonatal urine is not well-defined. Urine from neonates admitted to a single level IV neonatal intensive care unit was obtained to determine baseline concentration of two AMPs, Ribonuclease 7 (RNase 7) and Beta Defensin-1 (BD-1) and to define the relationship between AMP concentration and gestational age (GA). AMP levels were normalized to urine creatinine. RNase 7 and BD-1 were expressed in neonatal urine (n = 66) regardless of GA and as early as 22 weeks gestation. Urinary concentrations of both AMPs decreased as GA and birthweight increased. The overall median urinary RNase 7/UCr and BD-1/UCr values were 271 ng/mg, and 116 ng/mg, respectively. Median urinary concentrations of RNase 7/UCr for infants born at < 27, 27-32, 33-35 and ≥ 36 weeks were 569, 308, 254, and 124 ng/mg respectively. Similarly, the concentrations of BD-1/UCr at these GA were 166, 115, 108, and 14 ng/mg, respectively. Baseline neonatal urinary concentration of two AMPs (RNase 7 and BD-1) and the variation by GA were identified. This is an essential first step toward the potential utilization of AMPs in improving neonatal UTI diagnostics.

RESUMO

This educational article highlights the critical role of pediatric urology nursing research in improving the care of children with urological conditions. It discusses the multifaceted nature of pediatric urology nursing, addresses challenges such as limited nurse scientists and resource constraints, and highlights the need to overcome barriers to increase research involvement. The authors emphasize the importance of prioritizing research areas, the promotion of collaboration, and the provision of adequate funding and academic time for pediatric nurses to contribute to evidence-based practice, to improve patient outcomes. Furthermore, it highlights the importance of research in advancing nursing practice, shaping protocols, and advocating for the rights and needs of children with urological conditions and their families.

RESUMO

OBJECTIVE: To reveal barriers and opportunities to implement evidence for the management of pediatric kidney stone disease, we determined surgeon and institutional factors associated with preferences for the type of surgical intervention for kidney and ureteral stones. METHODS: We conducted a cross-sectional study of urologists participating in the Pediatric KIDney Stone Care Improvement Network (PKIDS) trial. Questionnaires ascertained strengths of urologists' preferences for types of surgery as well as characteristics of participating urologists and institutions. The outcome was the strength of preferences for ureteroscopy, shockwave lithotripsy, and percutaneous nephrolithotomy for four scenarios for which two alternative procedures are recommended by the AUA guidelines: (1) 2 cm kidney stone, (2) 9 mm proximal ureteral stone, (3) 1.5 cm lower pole kidney stone, (4) 1 cm nonlower pole kidney stone. Principal component analysis was performed to identify unique clusters of factors that explain surgical preferences. RESULTS: One hundred forty-eight urologists at 29 sites completed surveys. Stated preferences were highly skewed except for the choice between ureteroscopy and percutaneous nephrolithotomy for a 1.5 cm kidney stone. Shockwave lithotripsy ownership and local practice patterns most frequently associated with the strength of surgeons' preferences for the type of surgery. Principal component analysis revealed that three clusters of stone, patient, and heterogenous characteristics explained 30% of the variance in preferences. CONCLUSION: There is wide variation in the strengths of preferences for surgical interventions supported by current guidelines that are partially explained by surgeon and institutional characteristics. These results reveal opportunities to develop strategies for guidelines that consider real-world drivers of care.

RESUMO

INTRODUCTION: The ribonuclease (RNase) A superfamily encodes cationic antimicrobial proteins with potent microbicidal activity toward uropathogenic bacteria. Ribonuclease 6 (RNase6) is an evolutionarily conserved, leukocyte-derived antimicrobial peptide with potent microbicidal activity toward uropathogenic Escherichia coli (UPEC), the most common cause of bacterial urinary tract infections (UTIs). In this study, we generated Rnase6-deficient mice to investigate the hypothesis that endogenous RNase 6 limits host susceptibility to UTI. METHODS: We generated a Rnase6EGFP knock-in allele to identify cellular sources of Rnase6 and determine the consequences of homozygous Rnase6 deletion on antimicrobial activity and UTI susceptibility. RESULTS: We identified monocytes and macrophages as the primary cellular sources of Rnase6 in bladders and kidneys of Rnase6EGFP/+ mice. Rnase6 deficiency (i.e., Rnase6EGFP/EGFP) resulted in increased upper urinary tract UPEC burden during experimental UTI, compared to Rnase6+/+ controls. UPEC displayed increased intracellular survival in Rnase6-deficient macrophages. CONCLUSION: Our findings establish that RNase6 prevents pyelonephritis by promoting intracellular UPEC killing in monocytes and macrophages and reinforce the overarching contributions of endogenous antimicrobial RNase A proteins to host UTI defense.

RESUMO

ABSTRACTPurpose:

Literature pertaining to surgical disclosure to the pediatric patient is lacking. We hypothesized parents would find it difficult to disclose urologic surgery to a child.

Materials and Methods:

Parents of patients <5 years old undergoing urologic surgery were contacted for telephone survey. Parents were asked about future plans of surgical disclosure, comfort with disclosure, and any support received.

Results:

98 parents consented to study participation. 87% of surgeries were on the genitalia with 62% being minor genitalia surgery (i.e. circumcision). 70% of parents would tell their child about minor genital surgery while 84% would tell about major genital surgery (p=0.07). 4 of 20 parents of children undergoing hypospadias repair (major genital surgery) did not plan to tell their child about surgery. All parents of children undergoing non-genital surgery would tell. Of all parents planning to tell their children about surgery, only 14% were nervous. 34% of parents would find guidance in talking to their child helpful despite the majority (90%) stating no guidance had ever been provided.

Conclusions:

Parents seem comfortable discussing urologic surgeries with a child but about 1/3 would appreciate further counseling. 20% of parents of children undergoing hypospadias repair hope to avoid telling their child.
