Telerehabilitation for Post-Hospitalized COVID-19 Patients: A Proof-of-Concept Study During a Pandemic.

Purpose: Telerehabilitation could prevent sequelae from COVID-19. We aimed to assess the feasibility of telerehabilitation; describe pulmonary and functional profiles of COVID-19 patients; and explore the effect of telerehabilitation on improving pulmonary symptoms and quality of life.

Methods: We conducted a pre-experimental, pre-post pilot study.

Identification of a Novel Regulator of Clostridioides difficile Cortex Formation.

Clostridioides difficile is a leading cause of health care-associated infections worldwide. These infections are transmitted by C. difficile's metabolically dormant, aerotolerant spore form.

The effect of artificial X-rays on C-arm positioning performance in a simulated orthopaedic surgical setting.

Purpose: We designed an Artificial X-ray Imaging System (AXIS) that generates simulated fluoroscopic X-ray images on the fly and assessed its utility in improving C-arm positioning performance by C-arm users with little or no C-arm experience.

Methods: The AXIS system was comprised of an optical tracking system to monitor C-arm movement, a manikin, a reference CT volume registered to the manikin, and a Digitally Reconstructed Radiograph algorithm to generate live simulated fluoroscopic images. A user study was conducted with 30 participants who had little or no C-arm experience.
