External Validation of Brief Resolved Unexplained Events Prediction Rules for Serious Underlying Diagnosis.

Importance: The American Academy of Pediatrics (AAP) higher-risk criteria for brief resolved unexplained events (BRUE) have a low positive predictive value (4.8%) and misclassify most infants as higher risk (>90%). New BRUE prediction rules from a US cohort of 3283 infants showed improved discrimination; however, these rules have not been validated in an external cohort.

Relationship between pre-pregnancy body-mass-index and gestational age-specific risk of stillbirth and perinatal death in women with chronic hypertension.

Background: Obesity is a risk factor for stillbirth and perinatal death and is often accompanied by chronic hypertension; however, there are few studies on the relationship between pre-pregnancy BMI and gestational age (GA)-specific rates of stillbirth and perinatal death in women with chronic hypertension.

Objective: The objective of this study was to examine the relationship between pre-pregnancy BMI and GA-specific risk of stillbirth and perinatal death in the presence/absence of chronic hypertension.

Methods: This was a retrospective cohort study of all singleton births in the United States in 2016-17.

Characteristics of a revised quick sequential organ failure assessment score (RqSOFA) to predict in-hospital mortality of patients visiting the emergency department via ambulance: an observational cohort study.

The National Early Warning Score (NEWS), Quick Sequential Organ Failure Assessment (qSOFA), and modified qSOFA (MqSOFA) are scoring systems that rely on vital signs. However, NEWS is time-consuming, qSOFA has low sensitivity, and MqSOFA includes a difficult calculation. To address these issues, we developed the Revised qSOFA score (RqSOFA) that consists of percutaneous oxygen saturation, oxygen usage, Simple Shock Index, and the parameters of qSOFA.

Evaluating renal disease in pediatric-onset anti-neutrophil cytoplasmic antibody-associated vasculitis: disease course, outcomes, and predictors of outcome.

Objectives: We aimed to study the disease course, outcomes, and predictors of outcome in pediatric-onset anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) affecting the kidneys.

Methods: Patients eligible for this study had a diagnosis of granulomatosis with polyangiitis (GPA), microscopic polyangiitis (MPA), or ANCA positive pauci-immune glomerulonephritis, were ≤ 18 years at diagnosis, had renal disease defined by biopsy or dialysis dependence, and had clinical data at diagnosis and either 12- or 24-months. Ambispective data from the ARChiVE/PedVas Registry was used.

The Impact of Public Policy on Equitable Access to Technology for Children and Youth Living with Type 1 Diabetes in British Columbia, Canada.

Structural inequities impede technology uptake in marginalized populations living with type 1 diabetes (T1D). Our objective was to describe hemoglobin A1c (HbA), time in range (TIR), and pump use to evaluate the impact of a universal funding policy for continuous glucose monitoring (CGM) across levels of deprivation in children with T1D in the Canadian province of British Columbia (BC). Patients with T1D and at least one outpatient visit after June 10, 2020 (1-year before universal CGM funding) who were enrolled in the BC Pediatric Diabetes Registry were included ( = 477).
