Background: Adverse childhood experiences (ACEs) are pervasive and well-recognized as having lasting deleterious effects on the physical and mental health of those who experience them, particularly with accumulated exposure.

Objective: This study seeks to identify the perspectives of interprofessional health providers on their personal and professional experiences with ACEs, ACEs screening, how to work with people with ACEs, and make recommendations for the field.

Participants And Setting: Sixty-two health professionals and PhD students who completed at least one module of an online course and at least one of the accompanying discussion board sub-prompts.

Objective: To understand what longitudinal integrated clerkship (LIC) participants found meaningful and valuable about their experiences while grounded in a communicated narrative sensemaking (CNSM) framework.

Methods: Semi-structured interviews were conducted with a cohort of 3 LIC students and 7 of their 12 preceptors. Interviews were designed to elicit narratives ie time-ordered accounts of events, experiences, or reflections.

Background: The COVID-19 pandemic had large social effects, particularly in the fields of medicine and medical education. Medical organizations in the United States operate in overlapping contexts with interrelated goals inside multiple organizations, and the context of work strongly influenced how organizations were able to respond to COVID-19 restrictions.

Objective: This research examines the experience and impact of COVID-19 on the implementation of a Health Resources and Services Administration grant in a newly formed university medical office with the interrelated goals of health policy, health outreach, and medical education.

Purkinje cells have specialized intrinsic ionic conductances that generate high-frequency action potentials. Disruptions of their Ca or Ca-activated K (KCa) currents correlate with altered firing patterns in vitro and impaired motor behavior in vivo. To examine the properties of somatic KCa currents, we recorded voltage-clamped KCa currents in Purkinje cell bodies isolated from postnatal day 17-21 mouse cerebellum.

Purkinje neurons fire spontaneous action potentials at ∼50 spikes/sec and generate more than 100 spikes/sec during cerebellum-mediated behaviors. Many voltage-gated channels, including Ca channels, can inactivate and/or facilitate with repeated stimulation, raising the question of how these channels respond to regular, rapid trains of depolarizations. To test whether Ca currents are modulated during firing, we recorded voltage-clamped Ca currents, predominantly carried by P-type Ca channels, from acutely dissociated mouse Purkinje neurons at 30-33°C (1 mM Ca).
