Coordination between the eIF2 kinase GCN2 and p53 signaling supports purine metabolism and the progression of prostate cancer.

Cancers invoke various pathways to mitigate external and internal stresses to continue their growth and progression. We previously reported that the eIF2 kinase GCN2 and the integrated stress response are constitutively active in prostate cancer (PCa) and are required to maintain amino acid homeostasis needed to fuel tumor growth. However, although loss of GCN2 function reduces intracellular amino acid availability and PCa growth, there is no appreciable cell death.

Guideline Adoption for Community-Acquired Pneumonia in the Outpatient Setting.

Background: The Pediatric Infectious Diseases Society and Infectious Diseases Society of America national childhood community-acquired pneumonia (CAP) guideline encouraged the standard evaluation and treatment of children who were managed as outpatients. Our objectives were to (1) increase adherence to guideline-recommended diagnostics and antibiotic treatment of CAP at 5 pediatric primary care practices (PPCPs) by using quality-improvement methods and (2) evaluate the association between guideline adherence and unscheduled follow-up visits.

Methods: Immunocompetent children >3 months of age with no complex chronic conditions and who were diagnosed with CAP were eligible for inclusion in this stepped-wedge study.
