Background: New employees generally demonstrate lower productivity than experienced colleagues in non-healthcare sectors, but there is limited evidence on how tenure affects physician productivity.

Objective: To evaluate the association between tenure and clinical productivity for attending physicians in the Veterans Health Administration (VHA) and explore whether this relationship differs by prior VHA residency or fellowship training.

Design: Retrospective cohort evaluation.

Identifying the molecular effects of human genetic variation across cellular contexts is crucial for understanding the mechanisms underlying disease-associated loci, yet many cell types and developmental stages remain underexplored. Here, we harnessed the potential of heterogeneous differentiating cultures (HDCs), an in vitro system in which pluripotent cells asynchronously differentiate into a broad spectrum of cell types. We generated HDCs for 53 human donors and collected single-cell RNA sequencing data from over 900,000 cells.

Background: Mothers with mild to moderate depression in pregnancy are at risk of developing postpartum depression. Midwife-led continuity of care may support maternal mental health throughout the perinatal period. Research is needed to better understand how continuity of care may support mothers experiencing depression in pregnancy.

Pannexin 1 (PANX1) is upregulated in many cancers, where its activity and signalling promote tumorigenic properties. Here, we report a novel ∼25 kDa isoform of human PANX1 (hPANX1-25K) which lacks the N-terminus and was detected in several human cancer cell lines including melanoma, osteosarcoma, breast cancer and glioblastoma multiforme. This isoform was increased upon CRISPR/Cas9 deletion targeting the first exon near M1, suggesting a potential alternative translation initiation (ATI) site.
