Fact or Myth? Black Patients Do Not Want to Participate in Clinical Trials.

Objectives: To assess strategies for optimizing participation of underserved minorities in a blood-based early CRC detection test study (PREEMPT CRC; NCT04369053) at a hospital serving primarily Black patients.

Methods: Culturally sensitive, racially congruent research staff approached patients undergoing average-risk screening colonoscopy. Consent/study procedures were synchronized with clinical appointments.

Rebound in Fecal Testing, Colonoscopy Utilization, and Colorectal Neoplasia Detection During the COVID-19 Pandemic.

Introduction: The COVID-19 pandemic reduced colorectal cancer (CRC) screening, but the rebound in testing and outcomes after the pandemic has not been widely reported. We evaluated CRC test utilization and colorectal neoplasia detection among screening eligible patients in a large health system in 2020 and 2021, compared with 2019 (prepandemic).

Methods: Using a retrospective cohort study design, fecal immunochemical test (FIT) and colonoscopy utilization, FIT positivity, and neoplasia detection were evaluated annually in 2019-2021 among Kaiser Permanente Northern California patients aged 50-75 years overall and by sex, age, race and ethnicity, and spoken language preference.

Colorectal Cancer Screening and Social Needs.

Introduction: Colorectal cancer (CRC) is the second leading cause of cancer death in the United States. While patient-reported barriers have been previously described, few studies have analyzed how patients' social needs affect screening rates.

Methods: This cross-sectional study includes 3,443 Kaiser Permanente (KP) patients ages 50 to 75 years who completed the 2020 KP National Social Needs Survey.

Field-Induced Antiferromagnetic Correlations in a Nanopatterned Van der Waals Ferromagnet: A Potential Artificial Spin Ice.

Nano-patterned magnetic materials have opened new venues for the investigation of strongly correlated phenomena including artificial spin-ice systems, geometric frustration, and magnetic monopoles, for technologically important applications such as reconfigurable ferromagnetism. With the advent of atomically thin 2D van der Waals (vdW) magnets, a pertinent question is whether such compounds could make their way into this realm where interactions can be tailored so that unconventional states of matter can be assessed. Here, it is shown that square islands of CrGeTe vdW ferromagnets distributed in a grid manifest antiferromagnetic correlations, essential to enable frustration resulting in an artificial spin-ice.
