Built environment change for injury prevention: insights from public health professionals across public health units in Ontario, Canada.

Background: Road-related injuries and deaths are among the most significant and avoidable public health problems in Canada. Modifications to the built environment (BE) can reduce injury rates for vulnerable road users (VRUs) and other priority populations who experience disproportionate risk. This paper highlights public health professionals' experiences working in injury prevention across Ontario public health units (PHUs) navigating barriers and facilitators to BE change.

Aggregation unveiled: A sequential modelling approach to bark beetle outbreaks.

Tree-killing bark beetle infestations are a cause of massive coniferous forest mortality impacting forest ecosystems and the ecosystem services they provide. Models predicting bark beetle outbreaks are crucial for forest management and conservation, necessitating studies of the effect of epidemiological traits on the probability and severity of outbreaks. Due to the aggregation behaviour of beetles and host tree defence, this epidemiological interaction is highly non-linear and outbreak behaviour remains poorly understood, motivating questions about when an outbreak can occur, what determines outbreak severity, and how aggregation behaviour modulates these quantities.

Evaluating the Impact of Adjunctive Partial Cryoablation on Dual Checkpoint Inhibitor Immunotherapy Response in a Murine Model.

Purpose To evaluate the impact of adjunctive partial cryoablation on checkpoint inhibitor (CPI) immunotherapy response. Materials and Methods One hundred fifty-six mice (equal number of male and female animals) with dual-implanted tumor models were treated with dual CPI or a vehicle and randomized to treatment of a single tumor with partial cryoablation. Tumors were followed for 60 days following cryoablation for response assessment.

Ambassador Animals Do Not Have a Clear Effect on Visitor Conservation Knowledge and Attitudes Toward Exotic Pets at a Zoo Exhibit.

There is relatively little work examining visitor outcomes of ambassador animal programs, such as whether these programs are educationally effective or unintentionally promote exotic pet ownership. We designed a two-way factorial experiment to test whether ambassador animals enhanced or detracted from the educational outcomes of a zoo exhibit. We surveyed 312 visitors at the Oakland Zoo at a static exhibit focused on the illegal wildlife trade.
