Filling the gaps: A community case study in using an interprofessional approach and community-academic partnerships to address COVID-19-related inequities.

Public health challenges rapidly escalated during the COVID-19 pandemic. In response to a severe lack of resources and support in the near western suburbs of Chicago, the COVID Equity Response Collaborative: Loyola (CERCL) was established by an interprofessional team of Loyola University Chicago students, staff, and faculty. CERCL sought to minimize the negative impact of COVID-19 on vulnerable communities, those that are largely Black, Hispanic, or low-income. From April 2020 to the present, the collaborative utilized community-academic partnerships and interdisciplinary collaborations to conduct programming. CERCL's programming included free community-based testing, screening for and assistance with social determinants of health, dissemination of relevant and reliable COVID-related information, provision of personal protective equipment, and facilitation of access to vaccines. With partners, the collaborative conducted 1,500 COVID-19 tests, trained 80 individuals in contact tracing, provided over 100 individuals with specifically tailored resources to address social and legal needs, distributed 5,000 resource bags, held 20 community conversations, canvassed 3,735 homes, and hosted 19 vaccine clinics. Community-academic partnerships with the health system, community and governmental agencies, and the local public health department have been critical to CERCL efforts. The interdisciplinary and interprofessional successes demonstrated in this case study lends the example of a relevant, sustainable, and practical intervention to address nuanced public health issues.

Multigenerational consequences of early-life cannabinoid exposure in zebrafish.

While Δ9-tetrahydrocannabinol (THC) has been widely studied in the realm of developmental and reproductive toxicology, few studies have investigated potential toxicities from a second widely used cannabis constituent, cannabidiol (CBD). CBD is popularized for its therapeutic potential for reducing seizure frequencies in epilepsy. This study investigated developmental origins of health and disease (DOHaD) via multigenerational gene expression patterns, behavior phenotypes, and reproductive fitness of a subsequent F1 following an F0 developmental exposure of zebrafish (Danio rerio) to THC (0.024, 0.12, 0.6 mg/L; 0.08, 0.4, 2 µM) or CBD (0.006, 0.03, 0.15 mg/L; 0.02, 0.1, 0.5 µM). Embryonic exposure at these concentrations did not cause notable morphological abnormalities in either F0 or F1 generations. However, during key developmental stages (14, 24, 48, 72, and 96 h post fertilization) THC and CBD caused differential expression of c-fos, brain-derived neurotrophic factor (bdnf), and deleted-in-azoospermia like (dazl), while in F1 larvae only CBD differentially expressed dazl. Larval photomotor behavior was reduced (F0) or increased (F1) by THC exposure, while CBD had no effect on F0 larvae, but decreased activity in the unexposed F1 larvae. These results support our hypothesis of cannabinoid-related developmental neurotoxicity. As adults, F0 fecundity was reduced, but it was not in F1 adults. Conversely, in the adult open field test there were no significant effects in F0 fish, but a significant reduction in the time in periphery was seen in F1 fish from the highest THC exposure group. The results highlight the need to consider long-term ramifications of early-life exposure to cannabinoids.
