Post-hurricane fluid conservation measures fail to reduce IV fluid use in critically ill children.

Background: There are risks associated with excessive intravenous fluid (IVF) administration in critically ill children. Previous efforts have described opportunities to reduce positive cumulative fluid balance (CFB) in this population but have not been widely implemented. In the wake of Hurricane Helene, a national IVF shortage led to the implementation of IVF conservation guidelines.

Decreased Health Care Utilization in Complex Care Pediatrics After 1 Year with a Remote Examination Device.

Children with medical complexity are a growing population of pediatric patients with high health care utilization. Telemedicine could provide timely and reliable access to care that mitigates the associated burden of transportation and cost of expensive emergency room visits or hospitalizations. This study evaluated the health care utilization of patients in a complex care center (CCC) after a year with a remote examination telehealth device.

Fluid deresuscitation in critically ill children: comparing perspectives of intensivists and nephrologists.

Introduction: Fluid accumulation, presently defined as a pathologic state of overhydration/volume overload associated with clinical impact, is common and associated with worse outcomes. At times, deresuscitation, the active removal of fluid via diuretics or ultrafiltration, is necessary. There is no consensus regarding deresuscitation in children admitted to the pediatric intensive care unit.

Trauma promotes heparan sulfate modifications and cleavage that disrupt homeostatic gene expression in microvascular endothelial cells.

Heparan sulfate (HS) in the vascular endothelial glycocalyx (eGC) is a critical regulator of blood vessel homeostasis. Trauma results in HS shedding from the eGC, but the impact of trauma on HS structural modifications that could influence mechanisms of vascular injury and repair has not been evaluated. Moreover, the effect of eGC HS shedding on endothelial cell (EC) homeostasis has not been fully elucidated.

Myeloid-specific ferritin light chain deletion does not exacerbate sepsis-associated AKI.

Sepsis-associated acute kidney injury (SA-AKI) is a key contributor to the life-threatening sequelae attributed to sepsis. Mechanistically, SA-AKI is a consequence of unabated myeloid cell activation and oxidative stress that induces tubular injury. Iron mediates inflammatory pathways directly and through regulating the expression of myeloid-derived ferritin, an iron storage protein comprising ferritin light (FtL) and ferritin heavy chain (FtH) subunits.

Virtual Reality to Assess Resident Recognition of Impending Respiratory Failure During COVID-19.

Objectives: To assess the performance of pediatric residents in recognizing a decompensating patient with impending respiratory failure and appropriately escalating care using a virtual reality (VR) simulated case of an infant with bronchiolitis after an extended period of decreased clinical volumes during the coronavirus disease 2019 (COVID-19) pandemic.

Methods: Sixty-two pediatric residents at a single academic pediatric referral center engaged in a 30-minute VR simulation on respiratory failure in a 3-month-old admitted to the pediatric hospital medicine service with bronchiolitis. This occurred in a socially distant manner across the Zoom platform during the COVID-19 pandemic (January-April 2021).

Forelimb Resistance Exercise Protects Against Neuromuscular Junction Denervation in the SOD1-G93A Rat Model of ALS.

Introduction: The symptoms of Amyotrophic Lateral Sclerosis (ALS) include muscle weakness and eventual paralysis. These symptoms result from denervation of the neuromuscular junction (NMJ) and motor neuron cell death in the brain and spinal cord. Due to the "dying back" pattern of motor neuron degeneration, protecting NMJs should be a therapeutic priority.

A Precision Medicine Approach to Biomarker Utilization in Pediatric Sepsis-Associated Acute Kidney Injury.

Sepsis is a leading cause of morbidity and mortality in critically ill children, and acute kidney injury (AKI) is a frequent complication that confers an increased risk for poor outcomes. Despite the documented consequences of sepsis-associated AKI (SA-AKI), no effective disease-modifying therapies have been identified to date. As such, the only treatment options for these patients remain prevention and supportive care, both of which rely on the ability to promptly and accurately identify at risk and affected individuals.

Characterizing the frequency of modifiable histological changes observed on surveillance biopsies in pediatric kidney allograft recipients.

Background: Rejection is responsible for just under 50% of graft loss in the pediatric kidney transplant population. Early identification and treatment of allograft injury, specifically modifiable pathologies such as subclinical rejection (SCR), calcineurin inhibitor toxicity, and BK virus nephropathy, may improve allograft survival. Protocol surveillance biopsy (SB) currently offers the earliest opportunity for targeted interventions.
