An Efficient Model for Designing Medical Countermeasure Just-in-Time Training During Public Health Emergencies.

Rapidly training numerous staff and volunteers to distribute and dispense medical countermeasures is challenging because of limited resources and evolving information during public health emergencies. The Applied Learning and Development Team within the Division of State and Local Readiness at the Centers for Disease Control and Prevention (CDC) proposes just-in-time training (JITT) templates that can be rapidly customized and implemented early in any public health emergency. The proposed template model aligns with modular training design research to increase relevance and rapid deployment of training. Two case studies are described to demonstrate the potential for training templates to support medical countermeasure responses: (1) customization and implementation of a JITT to prepare staff to work on a CDC task force during the 2016-2017 Zika virus response and (2) a new modular, customizable course to teach the basics about working at a point-of-dispensing site. Flexible JITT templates in these cases reduce the burden on emergency planners and trainers, allowing for rapidly developed, customized training viable for all emergency responses.

Hermes transposon distribution and structure in Musca domestica.

Hermes are hAT transposons from Musca domestica that are very closely related to the hobo transposons from Drosophila melanogaster and are useful as gene vectors in a wide variety of organisms including insects, planaria, and yeast. hobo elements show distinct length variations in a rapidly evolving region of the transposase-coding region as a result of expansions and contractions of a simple repeat sequence encoding 3 amino acids threonine, proline, and glutamic acid (TPE). These variations in length may influence the function of the protein and the movement of hobo transposons in natural populations. Here, we determine the distribution of Hermes in populations of M. domestica as well as whether Hermes transposase has undergone similar sequence expansions and contractions during its evolution in this species. Hermes transposons were found in all M. domestica individuals sampled from 14 populations collected from 4 continents. All individuals with Hermes transposons had evidence for the presence of intact transposase open reading frames, and little sequence variation was observed among Hermes elements. A systematic analysis of the TPE-homologous region of the Hermes transposase-coding region revealed no evidence for length variation. The simple sequence repeat found in hobo elements is a feature of this transposon that evolved since the divergence of hobo and Hermes.
