Article Synopsis
  • The study investigated adverse neonatal outcomes in children born to mothers with different eating disorders, including anorexia nervosa (AN), bulimia nervosa (BN), and eating disorder not otherwise specified (EDNOS).
  • It analyzed data from over 1.5 million births in Denmark from 1991 to 2015, comparing outcomes based on whether the eating disorder diagnosis was recent (within 2 years of conception) or past (over 2 years before conception).
  • Findings showed that recent eating disorders, especially AN, were linked to higher risks of low birthweight, small-for-gestational-age, and preterm birth, emphasizing the need for better prevention and monitoring of eating disorders during pregnancy.

Eating disorders (EDs) commonly co-occur with other psychiatric and neurodevelopmental disorders including attention-deficit/hyperactivity disorder (ADHD) and autism spectrum disorder (ASD); however, the pattern of family history and genetic overlap among them requires clarification. This study investigated the diagnostic, familial, and genetic associations of EDs with ADHD and ASD. The nationwide population-based cohort study included all individuals born in Denmark, 1981-2008, linked to their siblings and cousins.

Article Synopsis
  • This study examines the links between eating disorders (EDs), attention-deficit/hyperactivity disorder (ADHD), and autism spectrum disorder (ASD) in a large population from Denmark spanning those born between 1981 and 2008.
  • It found significantly higher risks for developing EDs in individuals diagnosed with either ADHD (almost double) or ASD (over two and a half times more likely).
  • Mediation analysis indicated that mood or anxiety disorders might explain a substantial portion of the relationship between ADHD or ASD and EDs, highlighting potential genetic links between anorexia nervosa and these conditions.

Background: Diffuse midline glioma (DMG) is an aggressive pediatric central nervous system tumor with strong metastatic potential. As localized treatment of the primary tumor improves, metastatic disease is becoming a more important factor in treatment. We hypothesized that we could model craniospinal irradiation (CSI) through a DMG patient-derived xenograft (PDX) model and that CSI would limit metastatic tumor.

Aims: People with type 1 diabetes have a higher risk for cardiovascular disease (CVD). Reduced heart rate variability (HRV) is a clinical marker for CVD. In this observational study using continuous HRV measurement across 26 days, we investigated whether psychological stressors (diabetes distress, depressive symptoms) and glycaemic parameters (hypo- and hyperglycaemic exposure, glycaemic variability and HbA ) are associated with lower HRV in people with type 1 diabetes.

Introduction: The aim of this study was to determine the psychometric properties of the 12-Item Hypoglycemia Impact Profile (HIP12), a brief measure of the impact of hypoglycemia on quality of life (QoL) among adults with type 1 (T1D) or type 2 diabetes (T2D).

Research Design And Methods: Adults with T1D (n=1071) or T2D (n=194) participating in the multicountry, online study, 'Your SAY: Hypoglycemia', completed the HIP12. Psychometric analyses were undertaken to determine acceptability, structural validity, internal consistency, convergent/divergent validity, and known-groups validity.

Overexpression of Exportin-1 (), a key regulator of nuclear-to-cytoplasmic transport, is associated with inferior patient outcomes across a range of adult malignancies. Targeting XPO1 with selinexor has demonstrated promising results in clinical trials, leading to FDA approval of its use for multiple relapsed/refractory cancers. However, XPO1 biology and selinexor sensitivity in childhood cancer is only recently being explored.

Article Synopsis
  • - The study aimed to review how hypoglycemia affects the quality of life (QoL) in children and adolescents with type 1 diabetes by analyzing relevant existing research from various databases.
  • - A total of 27 studies were included, but findings were inconclusive due to inconsistent definitions of hypoglycemia and QoL across the studies.
  • - The research highlights a need for more in-depth studies using specific QoL measures for hypoglycemia, as current evidence on its impact on QoL is limited and insufficient.

Brain tumors are the most common solid tumor in children, and low-grade gliomas (LGGs) are the most common childhood brain tumor. Here, we report on 3 patients with LGG harboring previously unreported or rarely reported RAF fusions: FYCO1-RAF1, CTTNBP2-BRAF, and SLC44A1-BRAF. We hypothesized that these tumors would show molecular similarity to the canonical KIAA1549-BRAF fusion that is the most widely seen alteration in pilocytic astrocytoma (PA), the most common pediatric LGG variant, and that this similarity would include mitogen-activated protein kinase (MAPK) pathway activation.

Pediatric high-grade gliomas (pHGG) comprise a deadly, heterogenous category of pediatric gliomas with a clear need for more effective treatment options. Advances in high-throughput molecular techniques have enhanced molecular understanding of these tumors, but outcomes are still poor, and treatments beyond resection and radiation have not yet been clearly established as standard of care. In this review, we first discuss the history of treatment approaches to pHGG to this point.
