Operational Impacts of the Coronavirus Disease 2019 (COVID-19) Pandemic and Early Recovery Trends: University of Washington Anatomic Pathology Experience.

CONTEXT.­: The coronavirus disease 2019 pandemic, caused by the novel coronavirus severe acute respiratory syndrome coronavirus 2, has resulted in worldwide disruption to the delivery of patient care. The Seattle, Washington metropolitan area was one of the first in the United States affected by the pandemic. As a result, the anatomic pathology services at the University of Washington experienced significant changes in operational volumes early in the pandemic. OBJECTIVE.­: To assess the impact of coronavirus disease 2019 and both state and institutional policies implemented to mitigate viral transmission (including institutional policies on nonurgent procedures) on anatomic pathology volumes. DESIGN.­: Accessioned specimens from January to June 2020 were evaluated as coronavirus disease 2019 and institutional policies changed. The data were considered in these contexts: subspecialty, billable Current Procedural Terminology codes, and intraoperative consultation. Comparable data were retrieved from 2019 as a historical control. RESULTS.­: There was a significant reduction in overall accessioned volume (up to 79%) from prepandemic levels during bans on nonurgent procedures when compared with 2020 pre-coronavirus disease 2019 volumes and historical controls. The gastrointestinal and dermatopathology services were most impacted, and breast and combined head and neck/pulmonary services were least impacted. Current Procedural Terminology code 88305, for smaller/biopsy specimens, had a 63% reduction during nonurgent procedure bans. After all bans on procedures were lifted, the overall volume plateaued at 89% of prepandemic levels. CONCLUSIONS.­: A significant decrease in specimen volume was most strongly associated with bans on nonurgent procedures. Although all departmental areas had a decrease in volume, the extent of change varied across subspecialty and specimen types. Even with removal of all bans, service volume did not reach prepandemic levels.

Kinome and phosphoproteome of high-grade meningiomas reveal AKAP12 as a central regulator of aggressiveness and its possible role in progression.

There is a need to better understand meningioma oncogenesis for biomarker discovery and development of targeted therapies. Histological or genetic criteria do not accurately predict aggressiveness. Post-translational studies in meningioma progression are lacking. In the present work, we introduce a combination of mass spectrometry-based phosphoproteomics and peptide array kinomics to profile atypical and anaplastic (high-grade) meningiomas. In the discovery set of fresh-frozen tissue specimens (14), the A-kinase anchor protein 12 (AKAP12) protein was found downregulated across the grades. AKAP12 knockdown in benign meningioma cells SF4433 increases proliferation, cell cycle, migration, invasion, and confers an anaplastic profile. Differentially regulated pathways were characteristic of high-grade meningiomas. Low AKAP12 expression in a larger cohort of patients (75) characterized tumor invasiveness, recurrence, and progression, indicating its potential as a prognostic biomarker. These results demonstrate AKAP12 as a central regulator of meningioma aggressiveness with a possible role in progression.
