Tracheobronchopexy to Avoid Tracheostomy in Esophageal Atresia Patients With Severe Life-Threatening Tracheobronchomalacia.

Background: Esophageal atresia (EA) is associated with tracheobronchomalacia (TBM), which in its most severe form, causes blue spells, brief resolved unexplained events (BRUEs) that can require cardiopulmonary resuscitation (CPR), and positive pressure ventilation (PPV) or ventilator dependence, often requiring tracheostomy. We study the role of tracheobronchopexy, as an alternative to tracheostomy, in EA patients with severe life-threatening TBM.

Methods: We reviewed EA patients who underwent tracheobronchopexy for blue spells, BRUEs, and failure to wean PPV or extubate from February 2013 to September 2021 at two institutions.

Gender gap in surgical societies awards.

Introduction: Despite remarkable progress, gender inequality in medicine remains a significant issue. This disparity extends beyond clinical practices and educational programs; it is also evident in the recognition and awards received by surgeons. Underrepresentation of women in Surgical Society awards is a multi-layered issue that needs a holistic approach since these awards are used to hire, promote, and advance surgeons.

Enhanced Accumulation and Penetration of Magnetic Nanoclusters in Tumors Using an 8-Magnet Halbach Array Leads to Improved Cancer Treatment.

Nanoparticles have gained attention as drug delivery vehicles for cancer treatment, but often struggle with poor tumor accumulation and penetration. Single external magnets can enhance magnetic nanoparticle delivery but are limited to superficial tumors due to the rapid decline in the magnetic field strength with distance. We previously showed that a 2-magnet device could extend targeting to greater tissue depths.

Cystic masses of the pediatric lung: update on congenital pulmonary airway malformation and its differential diagnosis.

Localized cystic lung lesions in pediatric patients encompass a spectrum of benign and rare malignant conditions that are quite distinct from cystic lung disease arising in adulthood. The majority have historically fallen under the diagnostic category of "congenital pulmonary airway malformation," a term that has been used to denote a diverse group of diseases ranging in etiology from ectopia to bronchial atresia to mosaic oncogenic mutation or neoplasia. This article reviews the clinical characteristics, gross and histologic features, and pathogenetic underpinnings of congenital pulmonary airway malformation as well as lesions that enter its histologic differential diagnosis.

Look above the IRP: predicting abnormal confirmatory testing in patients with esophagogastric junction outflow obstruction.

Background: Esophagogastric junction outflow obstruction (EGJOO) is a manometric diagnosis based on Chicago Classification version 4.0 (CC4.0) that requires confirmatory testing for clinical relevancy.

Characterization of gallbladder disease in metachromatic leukodystrophy across the lifespan.

Metachromatic leukodystrophy (MLD) is a progressive demyelinating disorder resulting from the toxic accumulation of sulfatides. The stereotyped neurodegeneration of MLD is well understood, and cases are categorized into subtypes by age at neurologic onset: late infantile (LI), juvenile (J), and adult. The systemic burden of disease, such as gallbladder involvement, however, is less well characterized.

Genetic modifiers of asthma response to air pollution in children: An African ancestry GWAS and PM polygenic risk score study.

Rationale: Ambient air pollution (AAP) is linked to asthma outcomes, but predicting individual risk remains challenging. Understanding genetic contributors to AAP sensitivity may help overcome this gap.

Objectives: To determine if single nucleotide polymorphisms (SNPs) are associated with AAP sensitivity in children with asthma.

Health care transition quadruple aim outcomes for IDD: Scoping review.

Purpose: Structured HCT models addressing planning, transfer, and integration into adult care for adolescents and young adults with childhood-acquired chronic conditions are becoming more prevalent. However, consensus on outcome measures to assess health care transition (HCT) interventions particularly for intellectual and developmental disabilities (IDD) population is lacking. This scoping review identified potential HCT outcome measures for young adults (aged 18-26) with IDD using the Quadruple Aim Framework.

Dynamic contrast-enhanced magnetic resonance lymphangiography: a simple algorithm for image interpretation.

Dynamic contrast-enhanced magnetic resonance lymphangiography is a high-resolution imaging technique that has emerged as the preferred method for evaluating lymphatic anatomy and flow dynamics due to its precise anatomical detail. The lymphatic system has a complex anatomical distribution, and variability is common among individuals with cardiac abnormalities, particularly congenital heart disease. Lymphatic imaging has recently been revolutionized by the introduction of MR lymphangiography.

UHRF1 ubiquitin ligase activity supports the maintenance of low-density CpG methylation.

The RING E3 ubiquitin ligase UHRF1 is an established cofactor for DNA methylation inheritance. The model posits that nucleosomal engagement through histone and DNA interactions directs UHRF1 ubiquitin ligase activity toward lysines on histone H3 tails, creating binding sites for DNMT1 through ubiquitin interacting motifs (UIM1 and UIM2). However, the extent to which DNMT1 relies on ubiquitin signaling through UHRF1 in support of DNA methylation maintenance remains unclear.

The RNA chaperone protein ProQ is a pleiotropic regulator in enteropathogenic Escherichia coli.

Enteropathogenic Escherichia coli (EPEC) is a gastrointestinal pathogen that affects individuals of all age groups, with infections ranging from subclinical colonization to acute or persistent diarrhea. The bacterium's ability to cause diarrhea depends on the locus of enterocyte effacement (LEE) pathogenicity island. Although regulation of the LEE has been systematically characterized, until the last decade, studies mainly focused on its transcriptional control.

Global Genotype by Environment Prediction Competition Reveals That Diverse Modeling Strategies Can Deliver Satisfactory Maize Yield Estimates.

Predicting phenotypes from a combination of genetic and environmental factors is a grand challenge of modern biology. Slight improvements in this area have the potential to save lives, improve food and fuel security, permit better care of the planet, and create other positive outcomes. In 2022 and 2023 the first open-to-the-public Genomes to Fields (G2F) initiative Genotype by Environment (GxE) prediction competition was held using a large dataset including genomic variation, phenotype and weather measurements and field management notes, gathered by the project over nine years.

Providing pediatric neurocritical education across the ages: Bridging of neonatal neurocritical care into pediatric neurocritical care training.

Pediatric neurocritical care is a field dedicated to providing specialized assessment and care of critically-ill children with neurologic disease or at risk of neurologic compromise. Fellowship programs for providers interested in specializing in pediatric neurocritical care are growing and developing to meet the needs of trainees and the patient populations that they serve. Fetal and neonatal neurocritical care fellowship remains a separate opportunity for training; however, inclusion of fetal and neonatal neurology education into pediatric neurocritical care broadens understanding of normal and pathologic anatomy and physiology, diagnostic interpretation of the developing brain, targeted management interventions, family counseling and prognostication, and long-term optimization of outcomes.
