Welcome to March 2023 at Pediatric Critical Care Medicine (PCCM). There are three Editor’s Choices articles that each question established opinions and make us delve deeper into the relevant issues and potential implications for practice. The PCCM Connections for Readers focuses on biological mechanism–as a plea to our investigators and research authors, we do need to see more of this type of work at PCCM.


Klowak JA, Bijelic V, Barrowman N, et al; Genomics of Pediatric Septic Shock Investigators: The Association of Corticosteroids and Pediatric Sepsis Biomarker Risk Model (PERSEVERE)-II Biomarker Risk (1).

Are we any closer to solving the question of using corticosteroid therapy in children presenting with septic shock? In this retrospective study of almost 500 children separated into two categories using the PERSEVERE-II biomarker score, the authors tested whether there was an interaction between grouping, corticosteroid use, and outcome. Our editorial sets this information in a historical context, from 2009 to 2021 (2), and makes us think about precision medicine, endotypes, and the contemporary randomized controlled trial (RCT). This new article and editorial follow a theme in PCCM discussed in the September 2022 issue (3), and readers should review the authors’ other relevant work about the difficulty of RCTs in the septic shock population (4,5).


Brown KL, Moinuddin M, Jones A, et al: The Relationship Between Postoperative Complications and Children’s Quality of Life: A Mediation Analysis to Explore the Role of Family Factors (6).

In this multicenter research from the United Kingdom, the authors identified a cardiac postoperative group with multiple morbidities and sought to identify a causal mediation analysis of parental health-related quality of life at 6 weeks after cardiac surgery, and their child’s quality of life at 6 months. Over 400 children contributed to the primary outcome and these new data add insight into the complexity of outcomes and the potential scope of psychological interventions to support parents of children who experience perioperative morbidities. Add this reading to the authors’ recent report on postoperative morbidities and neurodevelopment (7), and we are now building a more complete picture of how best to study late outcomes after critical illness (8,9).


Iliopoulis I, Cooper DS, Reagor JA, et al: Absolute Versus Relative Near-Infrared Spectroscopy in Pediatric Cardiac Patients (10).

My third highlighted article is an analysis of near-infrared spectroscopy (NIRS) data: the devices and the validity of the measurements that we use during clinical care (10). Please read the report and even though it’s not what we thought or taught, our editorial writers argue that NIRS monitoring in patients with complex congenital heart disease is here to stay (11). Also, go back to a little-known Letter to the Editor in the January 2006 issue of PCCM with its powerful insights. In the letter, Britton Chance (1913–2010), the American founder of biomedical photonics and National Medal of Science winner in 1974, wrote to PCCM on the topic of quantification of brain oxygenation in humans in vivo (12).


This month there are two other areas of research that pick up on our previous themes. They are of particular interest because they address mechanism, and we need to understand clinical biology if we are to make progress in our field. The first topic is the endothelial glycocalyx. We have previously published a definitive review about the endothelial glycocalyx as a fundamental determinant of vascular permeability in sepsis (13), and a clinical research observation of glycocalyx degradation products contributing to metabolic acidosis following cardiopulmonary bypass (14). In a single-center research study from Colombia, the authors (same ones that wrote the previous PCCM definitive review) look at the time course of glycocalyx degradation in children with sepsis following a bolus of intravenous fluids (15). The article comes with an editorial (16).

The second topic is the morbidity of hyperoxia. In early 2022 we learned that there are 16 pediatric critical care studies with over 27 thousand patients that, collectively, suggests an association between hyperoxia and greater odds of mortality (17). We now have a mechanistic substudy nested within the pilot feasibility RCT of liberal versus conservative oxygenation targeting (i.e., pulse oximetry > 94% versus 88%−92%, respectively) (18). The authors report redox responses and gene expression of hypoxia-inducible factor 1a in the two oxygenation groups. Hopefully, their hypothesis will be tested in the now completed RCT of oxygen targeting and outcome in pediatrics (19).

Finally, another highlight for me is a narrative essay entitled “The Trip of a Lifetime” (20).
