Objective: To emphasize the urgent need for research efforts and application of goal-directed therapy in the pediatric transport environment.
Design: Review of existing literature and commentary on current pediatric transport practices.
Conclusions: Pediatric transport has evolved significantly since its inception >2 decades ago. Advancements in technology and therapeutic interventions now afford an opportunity to extend intensive care into the transport environment. However, misapplication of the concept of the golden hour has led to a focus on speed of transfer to tertiary care facilities, often delaying early, goal-directed therapeutic interventions. If we are to further improve outcomes for critically ill children, we must extend early institution of goal-directed therapy into the pretertiary hospital setting and bring expertise to the child.

Lung tissue from human patients and murine models of sickle cell disease pulmonary hypertension (SCD-PH) show perivascular regions with excessive iron accumulation. The iron accumulation arises from chronic hemolysis and extravasation of hemoglobin (Hb) into the lung adventitial spaces, where it is linked to nitric oxide depletion, oxidative stress, inflammation, and tissue hypoxia, which collectively drive SCD-PH. Here, we tested the hypothesis that intrapulmonary delivery of hemopexin (Hpx) to the deep lung is effective at scavenging heme-iron and attenuating the progression of SCD-PH.

Glyphosate, a widely used herbicide globally, has prompted concerns regarding its potential health impacts. This study aimed to explore the link between glyphosate exposure and renal function by combining NHANES, a zebrafish model, and metabolomics. A cross-sectional analysis of 2013-2014 NHANES data investigated the relationship between glyphosate exposure and renal function [albumin-to-creatinine ratio (ACR) and estimated glomerular filtration rate (eGFR)].

In the 21st century, thanks to advances in biotechnology and developing pharmaceutical technology, significant progress is being made in effective drug design. Drug targeting aims to ensure that the drug acts only in the pathological area; it is defined as the ability to accumulate selectively and quantitatively in the target tissue or organ, regardless of the chemical structure of the active drug substance and the method of administration. With drug targeting, conventional, biotechnological and gene-derived drugs target the body's organs, tissues, and cells that can be selectively transported to specific regions.

The cystic fibrosis transmembrane conductance regulator (CFTR) is an anion channel that is dysfunctional in individuals with cystic fibrosis (CF). The permeability of CFTR can be experimentally manipulated though different mechanisms, including activation via inducing the phosphorylation of residues in the regulatory domain as well as altering the gating/open probability of the channel. Phosphorylation/activation of the channel is achieved by exposure to compounds that increase intracellular cAMP, with forskolin and IBMX commonly used for this purpose.

The advent of next-generation sequencing (NGS) has revolutionized the analysis of genetic data, enabling rapid identification of pathogenic variants in patients with inborn errors of immunity (IEI). Sometimes, the use of NGS-based technologies is associated with challenges in the evaluation of the clinical significance of novel genetic variants. In silico prediction tools, such as SpliceAI neural network, are often used as a first-tier approach for the primary examination of genetic variants of uncertain clinical significance.
