Imaging NRF2 activation in non-small cell lung cancer with positron emission tomography.

Mutations in the NRF2-KEAP1 pathway are common in non-small cell lung cancer (NSCLC) and confer broad-spectrum therapeutic resistance, leading to poor outcomes. Currently, there is no means to non-invasively identify NRF2 activation in living subjects. Here, we show that positron emission tomography imaging with the system x radiotracer, [F]FSPG, provides a sensitive and specific marker of NRF2 activation in orthotopic, patient-derived, and genetically engineered mouse models of NSCLC.

Adapting the Planetary Health Report Card for Graduate Medical Training Programs.

Leading medical organizations recognize climate change as an urgent threat to public health and social justice. Medical students created the Planetary Health Report Card (PHRC) to evaluate and spur climate action in medical schools. Graduate medical trainees lack a similar tool to evaluate and improve their training programs and institutions.

Prevalence of Mild and Severe Cognitive Impairment in World Trade Center Exposed Fire Department of the City of New York (FDNY) and General Emergency Responders.

Background: The emergency personnel who responded to the World Trade Center (WTC) attacks endured severe occupational exposures, yet the prevalence of cognitive impairment remains unknown among WTC-exposed-FDNY-responders. The present study screened for mild and severe cognitive impairment in WTC-exposed FDNY responders using objective tests, compared prevalence rates to a cohort of non-FDNY WTC-exposed responders, and descriptively to meta-analytic estimates of MCI from global, community, and clinical populations.

Methods: A sample of WTC-exposed-FDNY responders (n = 343) was recruited to complete an extensive battery of cognitive, psychological, and physical tests.

Sodium Iodate: Rapid and Clinically Relevant Model of AMD.

Background: Age-related macular degeneration (AMD) is the most common cause of vision loss in people above the age of 50, affecting approximately 10% of the population worldwide and the incidence is rising. Hyperreflective foci (HRF) are a major predictor of AMD progression. The purpose of this study was to use the sodium iodate mouse model to study HRF formation in retinal degeneration.
