Cutting Edge Therapeutic Insights Derived from Molecular Biology of Pediatric High-Grade Glioma and Diffuse Intrinsic Pontine Glioma (DIPG)

Pediatric high-grade glioma (pHGG) and brainstem gliomas are some of the most challenging cancers to treat in children, with no effective therapies and 5-year survival at ~2% for diffuse intrinsic pontine glioma (DIPG) patients. The standard of care for pHGG as a whole remains surgery and radiation combined with chemotherapy, while radiation alone is standard treatment for DIPG. Unfortunately, these therapies lack specificity for malignant glioma cells and have few to no reliable biomarkers of efficacy. Recent discoveries have revealed that epigenetic disruption by highly conserved mutations in DNA-packaging histone proteins in pHGG, especially DIPG, contribute to the aggressive nature of these cancers. In this review we pose unanswered questions and address unexplored mechanisms in pre-clinical models and clinical trial data from pHGG patients. Particular focus will be paid towards therapeutics targeting chromatin modifiers and other epigenetic vulnerabilities that can be exploited for pHGG therapy. Further delineation of rational therapeutic combinations has strong potential to drive development of safe and efficacious treatments for pHGG patients

Vision-Specific Quality of Life in Patients With Post-Acute Sequelae of COVID-19 (PASC)

Infection with SARS-CoV-2 (COVID-19) involves multiple systems, including those for vision. People with post-acute sequelae of COVID-19 (PASC) have reported many neurological symptoms such as brain fog, memory difficulties, and headache, as well as vision related complaints. We sought to describe PASC-related visual symptoms in a cohort of non- hospitalized individuals presenting to our outpatient neurology practices and undergoing vision-specific quality of life assessments
