New guideline updates urinary infection guidance for children ages 8 days to 5 years

This clinical practice guideline updates earlier guidance on urinary tract infections in children from 8 days through 5 years of age. It reviews evidence and provides recommendations for evaluation, antibiotic treatment, imaging, and assessment of related conditions. The guideline reports that most key recommendations are based on low or very low certainty evidence.

Review finds uncertainty about molecular testing for urinary infections

A systematic review examined 12 studies of molecular tests for urinary tract infections in adults, including two randomized trials with 830 participants. The review found that PCR-based tests were more sensitive than standard urine cultures and were linked with short-term symptom improvement in both trials, but the tests were less specific and the overall clinical evidence remains limited.

Drug-resistant Proteus bacteria on vegetables matched urinary infection strains

A study in southern Brazil found that Proteus mirabilis from retail vegetables shared close genetic relationships, resistance genes and virulence features with isolates from community-acquired urinary tract infections. The findings identify food-associated bacteria as a possible reservoir of lineages linked to human disease, although the study did not prove transmission.

Researchers report stone cultures were linked with more sepsis after urinary stone procedures

A prospective observational study of 143 people undergoing procedures for urinary stones compared pre-surgery urine cultures with cultures taken from the stones during surgery. Stone cultures were positive more often and were associated with postoperative sepsis, while pre-surgery urine culture results were not significantly associated with sepsis. Because this was an observational study, the findings show associations rather than cause and effect.
