VA SHIELD: A Biorepository for Veterans and the Nation.

Background: To address the COVID-19 pandemic and future threats, VA leadership assembled research and clinical teams to coordinate a unified response, which included creating the VA Science and Health Initiative to Combat Infectious and Emerging Life-Threatening Diseases (VA SHIELD).

Observations: VA SHIELD is a comprehensive specimen and data repository. It links specific types of biospecimens with data regarding genetics, exposure, and disease risk by connecting data sources and the collections of biospecimens across clinical and research environments.

Nationwide Genomic Surveillance and Response to COVID-19: The VA SeqFORCE and SeqCURE Consortiums.

Background: The US Department of Veterans Affairs (VA) has dedicated significant resources toward countering the COVID-19 pandemic. Sequencing for Research Clinical and Epidemiology (SeqFORCE) and Sequencing Collaborations United for Research and Epidemiology (SeqCURE) were developed as clinical and research consortiums, respectively, focused on the genetic COVID-19 surveillance.

Observations: Through genetic sequencing, VA SeqFORCE and SeqCURE collaborations contributed to the COVID-19 pandemic response and scientific understanding.

Forest restoration and fuels reduction work: Different pathways for achieving success in the Sierra Nevada.

Fire suppression and past selective logging of large trees have fundamentally changed frequent-fire-adapted forests in California. The culmination of these changes produced forests that are vulnerable to catastrophic change by wildfire, drought, and bark beetles, with climate change exacerbating this vulnerability. Management options available to address this problem include mechanical treatments (Mech), prescribed fire (Fire), or combinations of these treatments (Mech + Fire).

The US Department of Veterans Affairs Science and Health Initiative to Combat Infectious and Emerging Life-Threatening Diseases (VA SHIELD): A Biorepository Addressing National Health Threats.

Background: The coronavirus disease 2019 (COVID-19) pandemic, caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has demonstrated the need to share data and biospecimens broadly to optimize clinical outcomes for US military Veterans.

Methods: In response, the Veterans Health Administration established VA SHIELD (Science and Health Initiative to Combat Infectious and Emerging Life-threatening Diseases), a comprehensive biorepository of specimens and clinical data from affected Veterans to advance research and public health surveillance and to improve diagnostic and therapeutic capabilities.

Results: VA SHIELD now comprises 12 sites collecting de-identified biospecimens from US Veterans affected by SARS-CoV-2.

Effects of Lag Time on Performance on ARRT's Primary Certification and Registration Exams.

Purpose: To investigate how lag time between graduation from an education program and exam date influenced candidates' performance on the American Registry of Radiologic Technologists (ARRT) certification and registration exams for radiography, nuclear medicine technology, radiation therapy, and magnetic resonance imaging.

Methods: Data for this quasi-experimental study were obtained for 39 898 candidates taking the 4 certification and registration exams from January 1, 2017, to December 31, 2019. Comparisons were made between candidates who took their certification exam within 8 weeks of graduation and candidates who waited 9 to 16 weeks after program completion.
