Introduction: Young children with type 1 diabetes (T1D) may be at particularly high risk of cognitive decline following diabetic ketoacidosis (DKA). However, studies of cognitive functioning in T1D typically examine school-age children. The goal of this study was to examine whether a single experience of DKA is associated with lower cognitive functioning in young children.

A history of Lyme disease can complicate the interpretation of Lyme disease serology in acutely symptomatic patients. We prospectively enrolled children undergoing evaluation for Lyme disease in the emergency department of one of eight participating Pedi Lyme Net centers. We selected symptomatic children with a Lyme disease history (definite, probable, or none) as well as an available research biosample.

Our objective was to explore recent trends in enteral antibiotic treatment of children with Lyme meningitis.
Methods: Using codes for case identification, we performed a multicenter retrospective study of patients ≤21 years of age presenting to a pediatric hospital contributing to the Pediatric Health Information System who were diagnosed with Lyme meningitis from 2015 to 2020.
Objectives: To identify independent predictors of and derive a risk score for invasive herpes simplex virus (HSV) infection.
Methods: In this 23-center nested case-control study, we matched 149 infants with HSV to 1340 controls; all were ≤60 days old and had cerebrospinal fluid obtained within 24 hours of presentation or had HSV detected. The primary and secondary outcomes were invasive (disseminated or central nervous system) or any HSV infection, respectively.
Lyme disease is commonly diagnosed by serologic response to Borrelia burgdorferi and related species, but the relationship between serologic targets and clinical features is unknown. We developed a multiantigen Luminex-based panel and evaluated IgG responses in 527 children 1 to 21 years of age assessed for Lyme disease across 4 Pedi Lyme Net emergency departments, including 127 Lyme cases defined by either an erythema migrans (EM) lesion or positive C6 enzyme immunoassay followed by immunoblotting and 400 patients considered clinical mimics. Of 42 antigens tested, 26 elicited specific reactivity in Lyme patients without marked age-dependent variation.

Study Design: We performed an 8-center prospective cohort study of children undergoing emergency department evaluation for Lyme disease limited to those who had an ECG obtained by their treating clinicians. The study cardiologist reviewed all ECGs flagged as abnormal by the study sites to assess for ECG evidence of carditis.
Objective: Fluid replacement to correct dehydration, acidosis, and electrolyte abnormalities is the cornerstone of treatment for diabetic ketoacidosis (DKA), but little is known about optimal fluid infusion rates and electrolyte content. The objective of this study was to evaluate whether different fluid protocols affect the rate of normalization of biochemical derangements during DKA treatment.
Research Design And Methods: The current analysis involved moderate or severe DKA episodes ( = 714) in children age <18 years enrolled in the Fluid Therapies Under Investigation in DKA (FLUID) Trial.
Objective: In Lyme disease endemic areas, Lyme and septic arthritis often present similarly. A published septic knee arthritis clinical prediction rule includes 2 high-risk predictors: absolute neutrophil count of 10,000 cells/mm3 or greater and erythrocyte sedimentation rate of 40 mm/h or greater. The objective of the study was to externally validate this prediction rule in a multicenter prospective cohort.

We sought to broadly validate this clinical prediction rule in children with meningitis undergoing evaluation for Lyme disease.
Methods: We performed a patient-level data meta-analysis of 2 prospective and 2 retrospective cohorts of children ≤21 years of age with cerebrospinal fluid pleocytosis who underwent evaluation for Lyme disease.
Importance: Acute kidney injury (AKI) occurs commonly during diabetic ketoacidosis (DKA) in children, but the underlying mechanisms and associations are unclear.
Objective: To investigate risk factors for AKI and its association with neurocognitive outcomes in pediatric DKA.
Design, Setting, And Participants: This cohort study was a secondary analysis of data from the Pediatric Emergency Care Applied Research Network Fluid Therapies Under Investigation in DKA Study, a prospective, multicenter, randomized clinical trial comparing fluid protocols for pediatric DKA in 13 US hospitals.
In 2015, we founded Pedi Lyme Net, a pediatric Lyme disease research network comprising 8 emergency departments in the United States. Of 2,497 children evaluated at 1 of these sites for Lyme disease, 515 (20.6%) were infected.

Research Design And Methods: We prospectively enrolled 758 children, 6-18 years old, who presented with DKA in a randomized multisite clinical trial evaluating intravenous fluid protocols for DKA treatment. DKA was moderate/severe in 430 children and mild in 328 children.
Objectives: To characterize hemodynamic alterations occurring during diabetic ketoacidosis (DKA) in a large cohort of children and to identify clinical and biochemical factors associated with hypertension.
Study Design: This was a planned secondary analysis of data from the Pediatric Emergency Care Applied Research Network Fluid Therapies Under Investigation in DKA Study, a randomized clinical trial of fluid resuscitation protocols for children in DKA. Hemodynamic data (heart rate, blood pressure) from children with DKA were assessed in comparison with normal values for age and sex.
Published Lyme meningitis treatment studies are limited by outcome measures that cannot capture day-to-day differences in clinical improvement. Our goal was to use expert consensus to develop a daily measurement instrument for assessing clinical improvement in children with Lyme meningitis. We assembled a panel of 24 nationally recognized Lyme disease experts to develop a pediatric daily symptom measurement instrument.
