Ballistics and wound ballistics of CO2‐powered dart guns in relation to ungulate dart injury and animal welfare

open access: yesWildlife Biology, EarlyView.
Large mammals are darted with dart guns to inject drugs or to collect biopsy tissue for capture, research, or veterinary purposes, especially for procedures involving wild and zoo animals. Darting is invasive and associated with risks of trauma, and severe and fatal dart injuries have been reported.

To guide or not to guide: A randomized study on the use of needle guide for chorionic villus sampling training

open access: yesActa Obstetricia et Gynecologica Scandinavica, EarlyView.
In this randomized study, novice performance improved when a needle guide was used during chorionic villus sampling (CVS) training. Incorporating needle guides into training may help ensure safer practice, particularly as clinical opportunities for skill development decrease. Abstract Introduction Chorionic villus sampling (CVS) is an invasive prenatal
