Variation in Antibiotic Susceptibility of Uropathogens by Age among Ambulatory Pediatric Patients
We compared uropathogen antibiotic susceptibility across age groups of ambulatory
pediatric patients. For Escherichia coli (n=5,099) and other Gram-negative rods (n=626), significant
differences (p<0.05) existed across age groups for ampicillin, cefazolin, and
trimethoprim/sulfamethoxazole susceptibility. In E. coli, differences in
trimethoprim/sulfamethoxazole susceptibility varied from 79% in children under 2 to 88% in ages 16-18 (p<0.001) while ampicillin susceptibility varied from 30% in children under 2 to 53% in ages 2-5 (p=0.015). Uropathogen susceptibility to common urinary anti-infectives may be lower in the
youngest children. Further investigation into these differences is needed to facilitate appropriate and prudent treatment of urinary tract infections.This is an author's peer-reviewed final manuscript, as accepted by the publisher.

Risk Factors for SARS-CoV-2 Infection Among US Healthcare Personnel, May-December 2020
To determine risk factors for coronavirus disease (COVID-19) among US healthcare personnel (HCP), we conducted a case-control analysis. We collected data about activities outside the workplace and COVID-19 patient care activities from HCP with positive severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) test results (cases) and from HCP with negative test results (controls) in healthcare facilities in 5 US states. We used conditional logistic regression to calculate adjusted matched odds ratios and 95% CIs for exposures. Among 345 cases and 622 controls, factors associated with risk were having close contact with persons with COVID-19 outside the workplace, having close contact with COVID-19 patients in the workplace, and assisting COVID-19 patients with activities of daily living. Protecting HCP from COVID-19 may require interventions that reduce their exposures outside the workplace and improve their ability to more safely assist COVID-19 patients with activities of daily living
Pediatric SARS-CoV-2 Seroprevalence, Oregon, USA, November 1, 2020–June 30, 2022
We estimated SARS-CoV-2 seroprevalence in children in Oregon, USA, at 6 time points. Seroprevalence increased linearly during November 2020–December 2021 and peaked in February 2022 at 38.8% (95% CI 32.8%–46.5%). We observed no increase in the seroprevalence trend after widespread school reopening. Seroprevalence estimates complement case-based cumulative incidence
Identification of Adenoviruses in Specimens from High-Risk Pediatric Stem Cell Transplant Recipients and Controlsâ–¿
Adenovirus infection is an important cause of morbidity and mortality in stem cell transplant recipients. We report species and type-specific analysis from a prospective study of high-risk adenovirus infections following hematopoietic progenitor cell transplantation prior to, during, and after treatment with cidofovir, as well as species analysis of contemporaneously collected samples from control patients. Nine different adenovirus types representing all six recognized species were identified, and mixed infections were commonly found in this group of patients
