In-person classroom instruction and risk of SARS-CoV-2 infection among undergraduates at Indiana University, Fall 2020.

To examine how in-person classroom instruction was related to risk of SARS-CoV-2 infection in undergraduate students. Indiana University undergraduate students (n = 69,606) enrolled in Fall 2020, when courses with in-person and remote instruction options were available. Students participated weekly in mandatory SARS-CoV-2 RT-PCR asymptomatic testing by random selection, supplemented with symptomatic testing as needed.

SARS-CoV-2 reinfections in a US university setting, Fall 2020 to Spring 2021.

Background: SARS-CoV-2 reinfections are a public health concern because of the potential for transmission and clinical disease, and because of our limited understanding of whether and how well an infection confers protection against subsequent infections. Despite the public health importance, few studies have reported rigorous estimates of reinfection risk.

Methods: Leveraging Indiana University's comprehensive testing program to identify both asymptomatic and symptomatic SARS-CoV-2 cases, we estimated the incidence of SARS-CoV-2 reinfection among students, faculty, and staff across the 2020-2021 academic year.

Perfectionism, impostor phenomenon, and mental health in medicine: a literature review.

Objectives: The aims of this review, focused on medical students, residents, and physicians, were a) to determine the levels of perfectionism and prevalence of impostor phenomenon, b) to assess the relationship between perfectionism, impostor phenomenon, and mental health, and c) explore how medical culture may influence these personality characteristics.

Methods: A narrative literature review was conducted. Search terms were entered into PubMed, PsychINFO, Web of Science, EMBASE, and Google Scholar without date or geographic restrictions.
