Glycogen drives tumour initiation and progression in lung adenocarcinoma.

Lung adenocarcinoma (LUAD) is an aggressive cancer defined by oncogenic drivers and metabolic reprogramming. Here we leverage next-generation spatial screens to identify glycogen as a critical and previously underexplored oncogenic metabolite. High-throughput spatial analysis of human LUAD samples revealed that glycogen accumulation correlates with increased tumour grade and poor survival.

Language Barriers in Appendicitis: What is the Cost?

Background: In clinical scenarios, pediatricians prefer patient history over imaging to diagnose pediatric appendicitis because they wish to limit their patients' exposure to radiation. Language barriers between providers and patients with limited English proficiency may increase adverse outcomes, require more imaging studies, and lead to higher costs in cases of pediatric appendicitis.

Methods: We queried the pediatric-National Surgical Quality Improvement Project database for patients under age 16 who received appendectomies from 2011-2021 at a single institution.
