Staged thoracoscopic internal traction approach for early repair of long-gap esophageal atresia (LGEA) with distal tracheoesophageal fistula (TEF).

Background: Long-gap esophageal atresia (LGEA) can complicate the management of esophageal atresia (EA) with or without a tracheoesophageal fistula (TEF). This series describes a short interval, staged, thoracoscopic internal traction approach for LGEA with distal TEF to manage complex anastomotic tension or an anatomically impossible esophageal anastomosis.

Methods: A retrospective review (2018-2024) was performed across four tertiary centers to identify patients with LGEA and distal TEF, managed with a staged, thoracoscopic internal traction approach.

Chlorpyrifos induces lung metastases and modulation of cancer stem cell markers in triple negative breast cancer model.

Breast cancer is a major public health problem, and distant metastases are the main cause of morbidity and mortality. Chlorpyrifos is an organophosphate that promotes Epithelial-Mesenchymal Transition-like phenotype in breast cancer cell lines and modulates the Breast Cancer Stem Cells activating two key processes related to the metastatic cascade. Here, we investigated whether Chlorpyrifos may induce distant metastases in an in vivo triple negative tumor model.

Improving Antibiotic Use in Argentine Pediatric Hospitals: A Process Evaluation Using Normalization Process Theory.

Introduction: In the pediatric setting, overprescribing of antibiotics contributes to the rise of multidrug-resistant organisms. Antimicrobial stewardship programs (ASPs) are recommended to optimize antibiotic use and combat resistance. However, the implementation of ASPs in low- and middle-income countries faces several challenges.

Open-label, controlled, phase 2 clinical trial assessing the safety, efficacy, and pharmacokinetics of INM004 in pediatric patients with Shiga toxin-producing Escherichia coli-associated hemolytic uremic syndrome.

Background: Shiga toxin-producing Escherichia coli-associated hemolytic uremic syndrome (STEC-HUS) is a severe condition mainly affecting children. It is one of the leading causes of acute kidney injury in the pediatric population. There is no established therapy for this disease.

Involvement of aquaporins in Shiga toxin-induced swelling and water transport dysfunction in human renal microvascular endothelial cells.

One of the hallmarks of Shiga toxin-producing Escherichia coli-associated hemolytic uremic syndrome (STEC-HUS) is kidney damage. Our previous research demonstrated that Shiga toxin type 2 (Stx2a) decreases cell viability and induces swelling of human glomerular endothelial cells (HGEC). However, Stx2a can disrupt net water transport across HGEC monolayers without affecting cell viability.

Esophageal achalasia: A case report in an adolescent.

Esophageal achalasia is an uncommon disease in pediatrics. With an insidious clinical presentation, diagnosis is delayed. Here we describe a case of esophageal achalasia in a 16-year-old girl, with the typical delay in consultation and diagnosis.

Spontaneous breathing trial in the weaning process from mechanical ventilation in pediatrics: outcome and predictive factors.

Introduction. spontaneous breathing trial (SBT) in weaning from pediatric invasive mechanical ventilation (IMV) is an endorsed practice, its positivity is based on clinical parameters; however, its results could be better documented. Objective.

Optimising antibacterial utilisation in Argentine intensive care units: a quality improvement collaborative.

Background: There is limited evidence from antimicrobial stewardship programmes in less-resourced settings. This study aimed to improve the quality of antibacterial prescriptions by mitigating overuse and promoting the use of narrow-spectrum agents in intensive care units (ICUs) in a middle-income country.

Methods: We established a quality improvement collaborative (QIC) model involving nine Argentine ICUs over 11 months with a 16-week baseline period (BP) and a 32-week implementation period (IP).

[Detection of microorganisms and resistance genes from positive blood cultures using the FilmArray® BCID2 panel: Experience in a pediatric hospital].

The rapid identification of microorganisms that cause bacteremia and their possible resistance markers are extremely important for the timely initiation of effective antibiotic therapy. The FilmArray® panel BCID2 (an automated rapid multiplex PCR assay) detects microorganisms and resistance genes from positive blood cultures within one hour. The aim of this study was to compare the results obtained from the FilmArray® Panel BCID2 and conventional culture in pediatric patients, as well as the reporting times of both methods.

Subjective body-related experiences, and perception of the interventions and empathy of the healthcare team in adolescents with overweight.

Introduction. Overweight adolescents are confronted daily with stereotypes that condition their body image, self-esteem, and mood. Objectives.

ATP-P2X7R pathway activation limits the Tfh cell compartment during pediatric RSV infection.

Background: Follicular helper T cells (Tfh) are pivotal in B cell responses. Activation of the purinergic receptor P2X7 on Tfh cells regulates their activity. We investigated the ATP-P2X7R axis in circulating Tfh (cTfh) cells during Respiratory Syncytial Virus (RSV) infection.

S100 proteins as potential predictive biomarkers of abatacept response in polyarticular juvenile idiopathic arthritis.

Background: Juvenile idiopathic arthritis (JIA) comprises a heterogeneous group of conditions that can cause marked disability and diminished quality of life. Data on predictors of clinical response are insufficient to guide selection of the appropriate biologic agent for individual patients. This study aimed to investigate the propensity of S100A8/9 and S100A12 as predictive biomarkers of abatacept response in polyarticular-course juvenile idiopathic arthritis (pJIA).

Imaging studies in evaluating children with stridor.

Stridor is a symptom of upper airway obstruction and may result from congenital or acquired causes. The diagnosis is usually clinical. If further investigation is necessary for differential diagnosis, endoscopy is the method of choice in most cases.

[Prevalence of hypophosphatemia in children with diabetic ketoacidosis and treatment with subcutaneous regular insulin. Observational study].

Unlabelled: Diabetic ketoacidosis (DKA) is one of the most serious complications of type 1 diabetes mellitus. Its treatment requires fluid and electrolyte replacement and insulin. Hypophosphatemia as a complication of treatment has been scarcely evaluated.

Exome Sequencing Has a High Diagnostic Rate in Sporadic Congenital Hypopituitarism and Reveals Novel Candidate Genes.

Context: The pituitary gland is key for childhood growth, puberty, and metabolism. Pituitary dysfunction is associated with a spectrum of phenotypes, from mild to severe. Congenital hypopituitarism (CH) is the most commonly reported pediatric endocrine dysfunction, with an incidence of 1:4000, yet low rates of genetic diagnosis have been reported.
