AI Article Synopsis
- The study investigates the prevalence of asymptomatic bacteriuria among preadolescent girls (ages 9-13) and its potential impact on future pregnancies.
- Out of 327 girls tested, 7 were found with asymptomatic bacteriuria, resulting in a prevalence rate of 2.1%, primarily linked to Escherichia coli.
- The nitrite test demonstrated high effectiveness for screening, with a sensitivity of 1.0 and negative predictive value of 1.0, suggesting it is a reliable method for early detection.
Article Abstract
Background: The detection of asymptomatic bacteriuria in preadolescent girls may be important due to its effects on subsequent pregnancies.
Objective: To describe the prevalence of asymptomatic bacteriuria in preadolescent girls and the value of the nitrite test for screening.
Material And Methods: Cross-sectional study in girls aged 9 to 13 years. Bacteriuria was defined as the growth of > 100,000 CFU/mL in 2 consecutive urine specimens.
Results: Three hundred and twenty seven girls were included. Asymptomatic bacteriuria was found in 7 girls, so the prevalence was 2.1% (95% CI, 1 to 4.4%). Escherichia coli was the isolated agent in all the cases. Focused interrogatory found history of urinary symptoms in 6 girls. The utility values of the nitrite test were: sensitivity, 1; specificity, 0.9; positive likelihood ratio, 10; and negative predictive value, 1.
Conclusions: The prevalence of asymptomatic bacteriuria in preadolescent girls in this Mexican study is similar to the one reported internationally; it is reasonable to consider its early detection to avoid its effects on future pregnancies. Nitrite test seems to be good for screening.

Prevalence and risk factors of antibiotic resistance for urinary tract infections in patients presenting to a Belgian tertiary care emergency department: testing the national guidelines against the local setting.
Acta Clin Belg
January 2025
Internal Medicine department, UZ Brussel, Internal Medicine Research Group, Vrije Universiteit Brussel, Brussels, Belgium.
Objectives: Urinary tract infections (UTIs) are an important cause of empiric antibiotic (over)treatment at the emergency department (ED). To enhance empiric antibiotic choices, mapping the national and local microbiology and antimicrobial resistance (AMR) patterns is crucial. This study aims to examine resistance patterns at a Brussels ED and to identify risk factors for AMR to evaluate current treatment guidelines and help combat AMR.

Importance: Enterococcus faecalis urinary tract infection (UTI) is common in postmenopausal females and these bacteria create biofilms that may reduce treatment efficacy. The role of local vaginal estrogen therapy in susceptibility to E. faecalis infection is unclear.

Article Synopsis
- Asymptomatic bacteriuria (ASB) is the presence of bacteria in urine without urinary tract infection symptoms, and treating it is generally not helpful.
- The study aimed to lower unnecessary antibiotic treatment for ASB in emergency departments (EDs) in the Netherlands using an educational and feedback-based strategy.
- Results showed a decrease in urinalyses ordered and a reduction in treatment duration for ASB patients, but there was no significant drop in the inappropriate use of antibiotics.
Validation and generalizability of an asymptomatic bacteriuria metric in critical access hospitals.

Article Synopsis
- The study aimed to adapt the Inappropriate Diagnosis of UTI (ID-UTI) measure for use in Critical Access Hospitals (CAHs), assessing its feasibility, validity, and reliability.
- Only 40% of participating CAHs met the target for case submissions, with the ID-UTI metric showing high specificity (100%) but low sensitivity (48.5%) compared to physician reviews.
- While the adapted measure was reliable (93% agreement), challenges remain in ensuring its consistent application across CAHs.
The rise, fall, and resurgence of phage therapy for urinary tract infection.

In the face of rising antimicrobial resistance, bacteriophage therapy, also known as phage therapy, is seeing a resurgence as a potential treatment for bacterial infections including urinary tract infection (UTI). Primarily caused by uropathogenic , the 400 million UTI cases annually are major global healthcare burdens and a primary cause of antibiotic prescriptions in the outpatient setting. Phage therapy has several potential advantages over antibiotics including the ability to disrupt bacterial biofilms and synergize with antimicrobial treatments with minimal side effects or impacts on the microbiota.
