Point-of-Care Ultrasound Track in an Academic Family Medicine Department.

Introduction: Point-of-care ultrasound (POCUS) is increasingly being employed in family medicine. Residency tracks can be an effective way to increase mastery in a specific subdiscipline for interested residents, but no studies exist on the implementation of a POCUS track in family medicine. We address this gap in the literature by assessing POCUS use by POCUS track residents compared to non-POCUS track residents and faculty in an academic family medicine department.

Incidence of Newborn Drug Testing and Variations by Birthing Parent Race and Ethnicity Before and After Recreational Cannabis Legalization.

Importance: Thirty-seven US states and the District of Columbia mandate reporting newborns with suspected prenatal substance exposure to the state, and punitive policies that link prenatal substance exposure to newborn drug testing (NDT) may lead to disproportionate reporting of Black parents to Child Protective Services. The impact of recreational cannabis legalization on racial disproportionality in NDT is unknown.

Objectives: To examine variations in the incidence and results of NDT by birthing parent race and ethnicity, variables associated with variation, and changes after statewide legalization of recreational cannabis.

The fat-like cadherin CDH-4 acts cell-non-autonomously in anterior-posterior neuroblast migration.

Directed migration of neurons is critical in the normal and pathological development of the brain and central nervous system. In Caenorhabditis elegans, the bilateral Q neuroblasts, QR on the right and QL on the left, migrate anteriorly and posteriorly, respectively. Initial protrusion and migration of the Q neuroblasts is autonomously controlled by the transmembrane proteins UNC-40/DCC, PTP-3/LAR, and MIG-21.
