The continuing need for dornase alfa for extracellular airway DNA hydrolysis in the era of CFTR modulators.

Introduction: The availability of cystic fibrosis transmembrane conductance regulator (CFTR) modulators opens the possibility of discontinuing some chronic pulmonary therapies to decrease cystic fibrosis (CF) treatment burden. However, CFTR modulators may not adequately address neutrophilic inflammation, which contributes to a self-perpetual cycle of viscous CF sputum, airway obstruction, inflammation, and lung function decline.

Areas Covered: This review discusses the emerging role of neutrophil extracellular traps in CF and its role in CF sputum viscosity, airway obstruction, and inflammation, based on a literature search of PubMed (1990-present).

Disposition and Follow-up for Low-Risk Febrile Infants: A Secondary Analysis of a Multicenter Study.

Objective: American Academy of Pediatrics guidelines recommend that febrile infants at low risk for invasive bacterial infection be discharged from the emergency department (ED) if primary care provider (PCP) follow-up occurs within 24 hours. We aimed to (1) assess the association between having electronic health record (EHR) documentation of a PCP and ED disposition and (2) describe documentation of potential barriers to discharge and plans for post-discharge follow-up in low-risk febrile infants.

Methods: We conducted a secondary analysis of a multicenter, cross-sectional study of low-risk febrile infants.

Management of race, ethnicity, and language data in the pediatric emergency department.

In this secondary analysis of a multicenter investigation, we describe several gaps in the collection and management of pediatric race, ethnicity, and language data. These findings highlight the ongoing need for reliable data management processes as a crucial step toward advancing pediatric health equity.

Baicalin alleviates angiotensin II-induced cardiomyocyte apoptosis and autophagy and modulates the AMPK/mTOR pathway.

As a main extraction compound from Scutellaria baicalensis Georgi, Baicalin exhibits various biological activities. However, the underlying mechanism of Baicalin on hypertension-induced heart injury remains unclear. In vivo, mice were infused with angiotensin II (Ang II; 500 ng/kg/min) or saline using osmotic pumps, followed by intragastrically administrated with Baicalin (5 mg/kg/day) for 4 weeks.

Anxiety among youth with food allergy.

Objective: Anxiety is among the major psychological concerns for children living with food allergy (FA). Yet research exploring the variables driving anxiety symptoms in FA remains sparse, and most studies still utilize homogeneous samples to assess anxiety symptoms. The current study seeks to evaluate the rates of clinically significant anxiety symptoms among a diverse sample of youth with FA and examine whether a heightened risk perception of FA outcomes and FA burden (vs.

Gut permeability is associated with lower insulin sensitivity in youth with perinatally acquired HIV.

The relationships between alterations in the intestinal barrier, and bacterial translocation with the development of metabolic complications in youth with perinatally acquired HIV (YPHIV) have not been investigated. The PHACS Adolescent Master Protocol enrolled YPHIV across 15 U.S.

Obesity and Extracorporeal Membrane Oxygenation.

Obesity is increasing in prevalence worldwide and carries a theoretical increased risk of morbidity and mortality in critical illness, including hypercoagulability, thrombosis, and renal dysfunction. Obesity has historically been considered a relative contraindication to candidacy for extracorporeal membrane oxygenation (ECMO); however, recent research has suggested that obesity may be associated with improved outcomes in ECMO. This review was conducted to assess and synthesize the existing literature on ECMO outcomes in the obese population.

Major adverse events in youth-onset type 1 and type 2 diabetes: The SEARCH and TODAY studies.

Aims: To determine contemporary incidence rates and risk factors for major adverse events in youth-onset T1D and T2D.

Methods: Participant interviews were conducted once during in-person visits from 2018 to 2019 in SEARCH (T1D: N = 564; T2D: N = 149) and semi-annually from 2014 to 2020 in TODAY (T2D: N = 495). Outcomes were adjudicated using harmonized, predetermined, standardized criteria.

Race, Ethnicity, Language, and the Treatment of Low-Risk Febrile Infants.

Importance: Febrile infants at low risk of invasive bacterial infections are unlikely to benefit from lumbar puncture, antibiotics, or hospitalization, yet these are commonly performed. It is not known if there are differences in management by race, ethnicity, or language.

Objective: To investigate associations between race, ethnicity, and language and additional interventions (lumbar puncture, empirical antibiotics, and hospitalization) in well-appearing febrile infants at low risk of invasive bacterial infection.

IGJ and SPATS2L immunohistochemistry sensitively and specifically identify BCR::ABL1+ and BCR::ABL1-like B-acute lymphoblastic leukaemia.

Therapeutic management and prognostication for patients with B-acute lymphoblastic leukaemia (B-ALL) require appropriate disease subclassification. BCR::ABL1-like B-ALL is unique in that it is defined by a gene expression profile similar to BCR::ABL1+ B-ALL rather than a unifying recurrent translocation. Current molecular/cytogenetic techniques to identify this subtype are expensive, not widely accessible, have long turnaround times and/or require an adequate liquid biopsy.

Challenges of Nutrition Support in Pediatric Patients Requiring Extracorporeal Membrane Oxygenation.

Nutrition support in critically ill infants and children remains an integral part of providing optimal care for these patients. The pediatric patient requiring extracorporeal membrane oxygenation therapy faces specific challenges to the provision of suitable nutrition support. In this review, we aimed to summarize the existing literature around some of the more challenging aspects of delivering appropriate nutrition to children receiving extracorporeal membrane oxygenation.

Mechanical ventilation during pediatric extracorporeal life support.

Purpose Of Review: To discuss the role of ventilator induced lung injury (VILI) and patient self-inflicted lung injury in ventilated children supported on extracorporeal membrane oxygenation (ECMO).

Recent Findings: While extracorporeal life support is used routinely used every day around the globe to support neonatal, pediatric, and adult patients with refractory cardiac and/or respiratory failure, the optimal approach to mechanical ventilation, especially for those with acute respiratory distress syndrome (ARDS), remains unknown and controversial. Given the lack of definitive data in this population, one must rely on available evidence in those with ARDS not supported with ECMO and extrapolate adult observations.

Hemodynamic Effects of a High-Frequency Oscillatory Ventilation Open-Lung Strategy in Critically Ill Children With Acquired or Congenital Cardiac Disease.

Objectives: To study the hemodynamic consequences of an open-lung high-frequency oscillatory ventilation (HFOV) strategy in patients with an underlying cardiac anomaly with or without intracardiac shunt or primary pulmonary hypertension with severe lung injury.

Design: Secondary analysis of prospectively collected data.

Setting: Medical-surgical PICU.

Definition, Incidence, and Epidemiology of Pediatric Acute Respiratory Distress Syndrome: From the Second Pediatric Acute Lung Injury Consensus Conference.

Objectives: In 2015, the Pediatric Acute Lung Injury Consensus Conference (PALICC) provided the first pediatric-specific definitions for acute respiratory distress syndrome (pediatric acute respiratory distress syndrome [PARDS]). These definitions have since been operationalized in cohort and interventional PARDS studies. As substantial data have accrued since 2015, we have an opportunity to assess the construct validity and utility of the initial PALICC definitions.

The obesity paradox: Retinopathy, obesity, and circulating risk markers in youth with type 2 diabetes in the TODAY Study.

Aim: To understand the relationship of obesity and 27 circulating inflammatory biomarkers to the prevalence of non-proliferative diabetic retinopathy (NPDR) in youth with type 2 diabetes.

Methods: Youth with type 2 diabetes who participated in the TODAY (Treatment Options for Type 2 Diabetes in Adolescents and Youth) study were followed for 2-6.5 years.

The use of tobramycin for Pseudomonas aeruginosa: a review.

Introduction: is a common respiratory pathogen that contributes to chronic pulmonary infection in individuals with cystic fibrosis. Guidelines recommend early intervention upon positive culture. Tobramycin has in vitro activity against Gram-negative bacteria, including , and TOBI Podhaler is indicated for the management of individuals with cystic fibrosis with infection.

Three Years of X + Y Scheduling: Longitudinal Assessment of Resident and Faculty Perceptions.

Objective: Five pediatric residency programs implemented true X + Y scheduling in 2018 where residents have continuity clinic in "blocks" rather than half-day per week experiences. We report the impact X + Y scheduling has on pediatric resident and faculty perceptions of patient care and other educational experiences over a 3-year timeframe.

Methods: Electronic surveys were sent to residents and faculty of the participating programs prior to implementing X + Y scheduling and annually thereafter (2018-2021).

Gut Dysfunction Markers Are Associated With Body Composition in Youth Living With Perinatally Acquired Human Immunodeficiency Virus.

Background: The association between gut dysfunction and body fat composition in youth living with perinatal human immunodeficiency virus infection (YPHIV) has not been investigated.

Methods: We included YPHIV aged 7-19 years from the Pediatric HIV/AIDS Cohort Study Adolescent Master Protocol with plasma available within 6 months of baseline whole-body dual energy x-ray absorptiometry (DXA) and HIV RNA ≤1000 copies/mL within 3 months of baseline DXA and a second DXA 2 years later. Plasma markers of bacterial translocation and gut barrier dysfunction (lipopolysaccharide binding protein [LBP], zonulin, and intestinal fatty acid binding protein [I-FABP]) were measured at baseline by enzyme-linked immunosorbent assay and log10 transformed.

A Human Trafficking Educational Program and Point-of-Care Reference Tool for Pediatric Residents.

Introduction: Trafficked youth experience complex health issues such as substance abuse, severe physical trauma, and sexual health problems, with many entering trafficking between 15 and 17 years old. There is increasing awareness of the need to educate pediatric health care providers on identifying and aiding trafficked children; however, critical gaps in the literature exist regarding educational sessions specific to the human trafficking of pediatric patients. Our objective was to implement and evaluate a survivor-informed educational session for pediatric resident physicians to improve identification of and assistance to trafficked youth in the clinical setting.

Sudden Death in the Young: Information for the Primary Care Provider.

There are multiple conditions that can make children prone to having a sudden cardiac arrest (SCA) or sudden cardiac death (SCD). Efforts have been made by multiple organizations to screen children for cardiac conditions, but the emphasis has been on screening before athletic competition. This article is an update of the previous American Academy of Pediatrics policy statement of 2012 that addresses prevention of SCA and SCD.

Metric Development for the Multicenter Improving Pediatric Sepsis Outcomes (IPSO) Collaborative.

Background: A 56 US hospital collaborative, Improving Pediatric Sepsis Outcomes, has developed variables, metrics and a data analysis plan to track quality improvement (QI)-based patient outcomes over time. Improving Pediatric Sepsis Outcomes expands on previous pediatric sepsis QI efforts by improving electronic data capture and uniformity across sites.

Methods: An expert panel developed metrics and corresponding variables to assess improvements across the care delivery spectrum, including the emergency department, acute care units, hematology and oncology, and the ICU.

Impact of X+Y Scheduling on Pediatric Resident and Faculty Perceptions of Education and Patient Care.

Purpose: Traditional half-day per week continuity clinic experiences can lead to fragmented education in both the inpatient and outpatient arenas. Five pediatric residency programs were granted the ability from the ACGME to create X+Y scheduling where residents have continuity clinic in "blocks" rather than half-day per week experiences. The aim of this study is to assess the impact X+Y scheduling has on pediatric resident and faculty perceptions of patient care and other educational experiences.

Development of a Quality Improvement Learning Collaborative to Improve Pediatric Sepsis Outcomes.

Pediatric sepsis is a major public health problem. Published treatment guidelines and several initiatives have increased adherence with guideline recommendations and have improved patient outcomes, but the gains are modest, and persistent gaps remain. The Children's Hospital Association Improving Pediatric Sepsis Outcomes (IPSO) collaborative seeks to improve sepsis outcomes in pediatric emergency departments, ICUs, general care units, and hematology/oncology units.

Shared Mental Models Among Clinical Competency Committees in the Context of Time-Variable, Competency-Based Advancement to Residency.

Purpose: To evaluate response process validity evidence for clinical competency committee (CCC) assessments of first-year residents on a subset of General Pediatrics Entrustable Professional Activities (EPAs) and milestones in the context of a national pilot of competency-based, time-variable (CBTV) advancement from undergraduate to graduate medical education.

Method: Assessments of 2 EPAs and 8 milestones made by the trainees' actual CCCs and 2 different blinded "virtual" CCCs for 48 first-year pediatrics residents at 4 residency programs between 2016 and 2018 were compared. Residents had 3 different training paths from medical school to residency: time-variable graduation at the same institution as their residency, time-fixed graduation at the same institution, or time-fixed graduation from a different institution.

International Practice Patterns of Antibiotic Therapy and Laboratory Testing in Bronchiolitis.

Background And Objectives: International patterns of antibiotic use and laboratory testing in bronchiolitis in emergency departments are unknown. Our objective is to evaluate variation in the use of antibiotics and nonindicated tests in infants with bronchiolitis in 38 emergency departments in Pediatric Emergency Research Networks in Canada, the United States, Australia and New Zealand, the United Kingdom and Ireland, and Spain and Portugal. We hypothesized there would be significant variation, adjusted for patient characteristics.
