Effect of Wearing a Face Mask on Hand-to-Face Contact by Children in a Simulated School Environment: The Back-to-School COVID-19 Simulation Randomized Clinical Trial.

Importance: Wearing a face mask in school can reduce SARS-CoV-2 transmission but it may also lead to increased hand-to-face contact, which in turn could increase infection risk through self-inoculation.

Objective: To evaluate the effect of wearing a face mask on hand-to-face contact by children while at school.

Design, Setting, And Participants: This prospective randomized clinical trial randomized students from junior kindergarten to grade 12 at 2 schools in Toronto, Ontario, Canada, during August 2020 in a 1:1 ratio to either a mask or control class during a 2-day school simulation.

Genetic simulation for high-stakes conversations.

Background: High-stakes conversations are frequent in Medical Genetics. News shared is often perceived as "bad" and can lead to patient hostility. Breaking bad news (BBN) is therefore a challenging clinical task for physicians and is often included as a foundational skill in medical education.
