KMT2A-rearranged leukemias are a highly aggressive subset of acute leukemia, characterized by poor prognosis and frequent relapses despite intensive treatment. Menin inhibitors, which target the critical KMT2A-menin interaction driving leukemogenesis, have shown promise in early clinical trials. However, resistance to these inhibitors, often driven by menin mutations or alternative oncogenic pathways, remains a significant challenge.

Cell patterning is essential for organized tissue development, enabling precise geometric arrangement of cells, body axis establishment and developmental timing. Here we investigate the role of physical forces and mechanical cues in organizing and maintaining cell morphological patterns during hindbrain neuropore closure, a critical morphogenetic event in vertebrate development. Through live-imaging in mouse embryos and cell-based biophysical modeling, we demonstrate that active cell crawling and actomyosin purse-string contraction at the neuropore border are insufficient to account for the observed cellular arrangements in space and time.

Article Synopsis
  • - The objective of the study was to review how neonatal status epilepticus (SE) is defined and measured, focusing on literature available on seizure burden in newborns.
  • - The review analyzed 44 studies that primarily included infants with conditions like hypoxic-ischemic encephalopathy, using continuous EEG (cEEG) for SE identification, and mostly defined SE via specific seizure durations.
  • - Key findings revealed significant variability in definitions of neonatal SE, with a consistent trend showing that higher seizure burden was linked to worse outcomes in the 16 studies that explored this relationship.

Adult glioblastoma (GBM) is a highly aggressive primary brain tumor, accounting for nearly half of all malignant brain tumors, with a median survival rate of only 8 months. Treatment for GBM is largely ineffective due to the highly invasive nature and complex tumor composition of this malignancy. MicroRNAs (miRNA) are short, non-coding RNAs that regulate gene expression by binding to messenger RNAs (mRNA).

Objectives: Anti-TIF1γ autoantibodies are associated with malignancy in adult-onset idiopathic inflammatory myopathy (IIM) and this risk is attenuated if patients are also positive for anti-specificity protein 4 (Sp4) or anti-cell division cycle apoptosis regulator protein 1 (CCAR1). In anti-TIF1γ positive US dermatomyositis (DM) patients, anti-Sp4 and anti-CCAR1 autoantibody frequencies are reported as 32% and 43% in adults and 9% and 19% in juveniles, respectively. This study aims to identify the frequency of anti-Sp4 and anti-CCAR1 in adult and juvenile UK anti-TIF1ƴ-positive myositis populations and report clinical associations.

Males typically outperform females in Olympic-style weightlifting, as judged by total weight lifted, and similarly heavier athletes outperform lighter athletes. Current methods can standardise weightlifting performances across body mass to compare different body mass classes, but they do not address the sex gap. This study introduces a novel approach that puts male and female performances on a single unified scale, across the range of body mass, allowing mixed sex teams to be compared.

The molecular basis of hypoprolactinaemia.

Rev Endocr Metab Disord

December 2024

Department of Paediatric Endocrinology, Great Ormond Street Children's Hospital, London, UK.

Hypoprolactinaemia is an endocrinopathy which is typically encountered as part of a combined pituitary hormone deficiency picture. The vast majority of genetic causes identified to date have been in the context of congenital hypopituitarism with multiple co-existent endocrinopathies. This is primarily with its closest hormonal relation, namely growth hormone.

Aims: DNA methylation profiling, recently endorsed by the World Health Organisation (WHO) as a pivotal diagnostic tool for brain tumours, most commonly relies on bead arrays. Despite its widespread use, limited data exist on the technical reproducibility and potential cross-institutional differences. The LOGGIC Core BioClinical Data Bank registry conducted a prospective laboratory comparison trial with 12 international laboratories to enhance diagnostic accuracy for paediatric low-grade gliomas, focusing on technical aspects of DNA methylation data generation and profile interpretation under clinical real-time conditions.

Article Synopsis
  • The study aimed to explore the vaccination rates and effectiveness of SARS-CoV-2 vaccines in children and young people (CYP) with life-limiting neurodisabilities using national hospital data from England between December 2020 and September 2022.
  • Out of 38,067 CYP identified, only 35% received at least one vaccine dose, with higher uptake in older, white children from less deprived areas; upon follow-up, vaccination did not significantly lower hospitalization rates after COVID-19 infection.
  • The vaccine showed significant protection against COVID-19 hospitalizations specifically during the Alpha-Delta variant phase, but had no impact during the Omicron variant phase, highlighting low vaccine uptake and disparities in vaccination by ethnicity and socio

Low-grade gliomas are a cause of severe and often life-long disability in children. Pathology plays a key role in their management by establishing the diagnosis, excluding malignant alternatives, predicting outcomes and identifying targetable genetic alterations. Molecular diagnosis has reshaped the terrain of pathology, raising the question of what part traditional histology plays.

Acute chest syndrome (ACS) is a leading cause of respiratory distress and hospitalisation in children with sickle cell disease (SCD). The aetiology is multifactorial and includes fat embolism, venous thromboembolism, alveolar hypoventilation and respiratory infections, with the latter being particularly common in children. These triggers contribute to a vicious cycle of erythrocyte sickling, adhesion to the endothelium, haemolysis, vaso-occlusion and ventilation-perfusion mismatch in the lungs, resulting in the clinical manifestations of ACS.

Complementary feeding (CF) may influence later eating behaviour and growth. Our previous Randomised Control Trial (RCT) reported that new CF guidelines (NCFGs) implemented in 6-12-month-old infants in Bogota, Colombia, had positive short-term effects on red meat, vegetable and fruit consumption. Here, we assessed the effects of the NCFGs on food consumption, eating behaviour and growth at 6 years of age.
