Clinical Full-Time Equivalent in PICUs: Survey of the U.S. Pediatric Critical Care Chiefs Network, 2020-2022.

Objectives: To inform workforce planning for pediatric critical care (PCC) physicians, it is important to understand current staffing models and the spectrum of clinical responsibilities of physicians. Our objective was to describe the expected workload associated with a clinical full-time equivalent (cFTE) in PICUs across the U.S.

Retrospective observational study of chloral hydrate use in mechanically-ventilated pediatric intensive care unit (PICU) patients 2012-2017.

Chloral hydrate (CH) has long been utilized as a pediatric procedural sedation agent. However, very little is published describing CH use in a pediatric intensive care unit (PICU) setting. The aim of this retrospective observational cohort study was to investigate and describe the use of CH in mechanically-ventilated, critically ill children at a large pediatric tertiary referral hospital.

Multi-center retrospective study of children with sickle cell disease admitted to pediatric intensive care units in the United States.

Data on outcomes and interventions for children with sickle cell disease (SCD) admitted to a pediatric intensive care units (PICU) are unknown. We provide the first comprehensive multi-center report on PICU interventions associated with death, the need for invasive respiratory support or stroke among critically ill children with SCD. We collected retrospective multi-center cohort data from January 1, 2012 to December 31, 2019 utilizing the Virtual Pediatric Systems, LLC database.

Guidance for Structuring a Pediatric Intermediate Care Unit.

The purpose of this policy statement is to update the 2004 American Academy of Pediatrics clinical report and provide enhanced guidance for institutions, administrators, and providers in the development and operation of a pediatric intermediate care unit (IMCU). Since 2004, there have been significant advances in pediatric medical, surgical, and critical care that have resulted in an evolution in the acuity and complexity of children potentially requiring IMCU admission. A group of 9 clinical experts in pediatric critical care, hospital medicine, intermediate care, and surgery developed a consensus on priority topics requiring updates, reviewed the relevant evidence, and, through a series of virtual meetings, developed the document.

Variations in analgesic, sedation, and delirium management between trauma and non-trauma critically ill children.

Introduction: Studies have shown the benefit of intensive care unit (ICU) bundled protocols; however, they are primarily derived from medical patients. We hypothesized that patients and their medication profiles are different between critically ill medical, surgical, and trauma patients.

Methods: The Pediatric Health Information System 2017 dataset was used to perform a retrospective cohort study of critically ill children.

Testing positive pressure delivered from commercial and WHO-style pediatric bubble CPAP devices.

Background/aim: Low-cost commercial bCPAP devices have been deployed in resource-limited settings to treat neonatal respiratory failure. The use of these devices has increased access to pediatric respiratory support for infants. However, constrained resources may result in substitution of recommended consumables and/or use in older age groups.

Derangement of Arginine and Related Amino Acids in Children Undergoing Surgery for Congenital Heart Disease With Cardiopulmonary Bypass.

Unlabelled: Arginine is a conditionally essential amino acid, the precursor for nitric oxide and a key factor in cell proliferation, protein synthesis, and energy metabolism. When there is increased demand in the setting of inflammation, ischemia-reperfusion injury, and organ dysfunction, endogenous arginine production falls short, and external supplementation may be necessary. The goal of this study was to assess changes in concentrations of plasma arginine, citrulline, ornithine, glutamine, and plasma arginase in infants and children undergoing surgery for congenital heart disease with cardiopulmonary bypass.

Outcomes Using a Postoperative Protocol in Pediatric Single-Stage Laryngotracheal Reconstruction.

Objectives: The aim of this study was to evaluate single-stage laryngotracheal reconstruction (ssLTR) outcomes before and after the implementation of a postoperative care protocol in pediatric patients.

Methods: A case-control study with chart review was conducted at 2 tertiary academic centers from 2010 to 2016. Pediatric patients who underwent ssLTR with a postoperative care protocol were compared with those who did not receive care under this protocol.

Early Suppression of Macrophage Gene Expression by .

is an intracellular parasite that resides mostly in macrophages. Both the parasite genome and the clinical disease manifestations show considerable polymorphism. Clinical syndromes caused by include localized cutaneous (CL), mucosal (ML), and disseminated leishmaniasis (DL).

LRRC8A channels support TNFα-induced superoxide production by Nox1 which is required for receptor endocytosis.

Leucine Rich Repeat Containing 8A (LRRC8A) is a required component of volume-regulated anion channels (VRACs). In vascular smooth muscle cells, tumor necrosis factor-α (TNFα) activates VRAC via type 1 TNFα receptors (TNFR1), and this requires superoxide (O) production by NADPH oxidase 1 (Nox1). VRAC inhibitors suppress the inflammatory response to TNFα by an unknown mechanism.

Pediatric posterior reversible encephalopathy syndrome presenting with isolated cerebellar edema and obstructive hydrocephalus.

In this report, the authors describe the case of a teenage boy who presented with hypertensive emergency, posterior reversible encephalopathy syndrome, and hydrocephalus due to fourth ventricle outlet obstruction. Posterior reversible encephalopathy syndrome is a well-characterized but uncommon syndrome in children that is generally triggered by severe hypertension. The unusual clinical picture of this patient, who had isolated cerebellar edema leading to obstructive hydrocephalus, has been rarely described in children.

Variable expressivity and clinical heterogeneity can complicate the diagnosis and management of Pfeiffer syndrome.

We report here a newborn female infant with striking features consistent with severe Pfeiffer syndrome (PS). Pfeiffer syndrome is a rare craniofacial disorder that has an autosomal dominant mode of inheritance (OMIM 101600). Our patient had unexpected differences between her clinical features and those predicted from her genetic tests.

Genetic admixture in Brazilians exposed to infection with Leishmania chagasi.

Visceral leishmaniasis (VL) in northeast Brazil is a disease caused by infection with the protozoan Leishmania chagasi. Infection leads to variable clinical outcomes ranging from asymptomatic infection to potentially fatal disease. Prior studies suggest the genetic background of the host contributes to the development of different outcomes after infection, although it is not known if ancestral background itself influences outcomes.

Macrophage and T-cell gene expression in a model of early infection with the protozoan Leishmania chagasi.

Visceral leishmaniasis is a potentially fatal infectious disease caused by the protozoan parasite Leishmania infantum/chagasi in the New World, or by L. donovani or L. infantum/chagasi in the Old World.

Genetic predisposition to self-curing infection with the protozoan Leishmania chagasi: a genomewide scan.

The protozoan Leishmania chagasi can cause disseminated, fatal visceral leishmaniasis (VL) or asymptomatic infection in humans. We hypothesized that host genetic factors contribute to this variable response to infection. A family study was performed in neighborhoods of endemicity for L.
