In vitro liver models combined with metabolomics approaches offer promising alternatives to animal testing in toxicology. In this study, we investigated concentration-dependent effects of hydrogen peroxide on the intra- and extracellular metabolome of HepG2 cells using 1H Nuclear Magnetic Resonance spectroscopy.

Systemic Epstein-Barr virus-positive T-cell lymphoma of childhood (STCLC) is a rare and highly aggressive malignancy with a dismal prognosis and no standard curative treatment. This report describes the first reported case of STCLC in a White child who, after experiencing failure with intensive chemotherapy regimens, achieved a complete response following targeted immunotherapy.
Global rates of invasive Group A Streptococcus (iGAS) disease surged from September 2022, exceeding pre-COVID-19 pandemic levels, showing atypical seasonality and disproportionately affecting children. We previously described the epidemiology of iGAS among Australian children from mid-2018 to end 2022 using data from the Paediatric Active Enhanced Diseases network and here provide updated clinical epidemiology for 2023 and 2024 to help inform public health strategies.
Wheezing and asthma exacerbations are leading causes of pediatric hospital admissions. Predicting which children will experience persistent exacerbations remains challenging. Prior research has identified immune endotypes in the nasal epithelium of children with acute asthma and wheezing, characterized by varying balances of interferons and inflammatory markers. Notably, children exhibiting low interferon responses coupled with high inflammation are at an increased risk for recurrent respiratory exacerbations.

Nonvital pulp therapy is a treatment option that can preserve pathologically affected primary teeth and contribute to space maintenance. This retrospective case series examined the healing effects in infected primary teeth after pulpectomy using mineral trioxide aggregate obturation and eruption characteristics of the succedaneous teeth.
Hematopoietic stem cells are defined by their remarkable self-renewal and differentiation capacities, giving rise to progenitors that generate diverse blood and immune cell lineages through the tightly regulated process of hematopoiesis. This process is governed by key transcription factors that control gene expression programs essential for cellular homeostasis, differentiation, and lineage commitment.
Heart valve disease (HVD) can cause morbidity and impairment of quality of life (QOL) both before and after intervention. However, descriptions of the QOL of people with HVD across the disease course are limited. We aimed to collect the experience of people living with HVD through qualitative interviews, focusing on how HVD impacts their self-perceived QOL.
Post-acute sequelae of COVID-19 (PASC), or long COVID, are a public health concern. While most recover from SARS-CoV-2 infections within weeks, some experience persistent symptoms. Here, we quantified the association between repeated SARS-CoV-2 infections and the risk of hospital-diagnosed PASC.
