Iowa emergency departments lack board-certified emergency physicians: A comprehensive statewide emergency department workforce study.

Introduction: The emergency physician (EP) workforce has been a recent focus after a workforce projection predicted a surplus of EPs by 2030. A previous study of Iowa emergency departments (EDs) demonstrated wide variability in ED staffing patterns and attributed it to the lack of EP job candidates. With the recent increase in emergency medicine (EM) residency positions, the objectives of this study were to understand how Iowa ED physician staffing has changed in regard to presence of board-certified EPs and what operational differences in Iowa EDs may be associated with staffing to provide insight into what may be occurring in other predominantly rural states.

Interlaboratory Measurement of Adeno-Associated Virus: Comparative Quantification of Full and Empty Capsids.

Recombinant adeno-associated virus (AAV) is one of the main viral vector-based gene therapy platforms. AAV is a virus consisting of a ≈25 nm diameter capsid with a ≈4.7 kb cargo capacity.

An Online Resident-as-Teacher Curriculum Improves First-Year Residents' Self-Confidence Teaching in the Clinical Learning Environment.

We implemented an online Resident-as-Teacher curriculum for all incoming residents (PGY1s) to provide them with a basic foundation for effective teaching in the clinical learning environment. The curriculum consisted of 5 asynchronous modules delivered via the web from 2017-2021. Prior to starting the course, the PGY1s completed a self-assessment of their teaching ability (pre-test) and then again 7-8 months after completing the course (post-test).

Comparison of Protein Particle Formation in IgG1 mAbs Formulated with PS20 Vs. PS80 When Subjected to Interfacial Dilatational Stress.

Polysorbates (PS) are nonionic surfactants that are commonly included in protein formulations to mitigate the formation of interfacial stress-induced protein particles and thus increase their long-term storage stability. Nonetheless, factors that dictate the efficiency of different polysorbates in mitigating protein particle formation, especially during the application of interfacial stresses, are often ill defined. Here, we used a Langmuir trough to determine the surface activity of two IgG1 monoclonal antibodies formulated with two different polysorbates (PS20 and PS80) when subjected to interfacial dilatational stress.
