Accuracy of pathogen diagnostic codes for acute hematogenous musculoskeletal infections in children.

Administrative databases are powerful tools for pediatric research but lack patient-level microbiology results. This study aimed to determine the accuracy of pathogen discharge diagnosis codes for children hospitalized with acute hematogenous musculoskeletal infections (MSKIs). Medical records for 244 children hospitalized with acute hematogenous MSKIs were manually reviewed to determine which bacterial pathogen, if any, was identified for each MSKI based on microbiology results obtained during the hospitalization.

When to Use Rectangular Waveforms in Dielectrophoresis Application to Increase Separation and Sorting Efficiency.

In this study, the influence of using rectangular waveforms is comprehensively investigated on the separation and sorting efficiency of dielectrophoretic (DEP) processes. Besides positive effects on DEP experiments, cases of a diminished force due to rectangular waveforms are investigated and discussed. This investigation encompasses two primary experimental setups.

Clinical Impact of Pleural Fluid Streptococcus pneumoniae Polymerase Chain Reaction Testing in Children With Complicated Pneumonia.

Background: While Streptococcus pneumoniae (Spn) is the leading cause of pediatric complicated community-acquired pneumonia (cCAP), it is infrequently recovered by culture-based methods. We studied the real-world clinical impact of an Spn polymerase chain reaction (PCR) assay for pleural fluid.

Methods: This pre-post quasi-experimental cohort study compared pathogen detection, antibiotic usage, and outcomes in children hospitalized with cCAP requiring pleural effusion or empyema drainage at Children's Hospital Colorado between 2016 and 2023.

Multimodal Surveillance Model for Enterovirus D68 Respiratory Disease and Acute Flaccid Myelitis among Children in Colorado, USA, 2022.

Surveillance for emerging pathogens is critical for developing early warning systems to guide preparedness efforts for future outbreaks of associated disease. To better define the epidemiology and burden of associated respiratory disease and acute flaccid myelitis (AFM), as well as to provide actionable data for public health interventions, we developed a multimodal surveillance program in Colorado, USA, for enterovirus D68 (EV-D68). Timely local, state, and national public health outreach was possible because prospective syndromic surveillance for AFM and asthma-like respiratory illness, prospective clinical laboratory surveillance for EV-D68 among children hospitalized with respiratory illness, and retrospective wastewater surveillance led to early detection of the 2022 outbreak of EV-D68 among Colorado children.
