A cell-based Papain-like Protease (PLpro) activity assay for rapid detection of active SARS-CoV-2 infections and antivirals.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and its variants are a continuous threat to human life. An urgent need remains for simple and fast tests that reliably detect active infections with SARS-CoV-2 and its variants in the early stage of infection. Here we introduce a simple and rapid activity-based diagnostic (ABDx) test that identifies SARS-CoV-2 infections by measuring the activity of a viral enzyme, Papain-Like protease (PLpro).

Magnetic Resonance Imaging Availability Reduces Computed Tomography Use for Pediatric Appendicitis Diagnosis.

Objectives: To determine if introducing magnetic resonance imaging (MRI) as an imaging option for children with suspected appendicitis and an inconclusive ultrasound reduces computed tomography (CT) use.

Methods: This is a retrospective cohort study of patients aged 5 to 18 years who presented to a pediatric emergency department (ED) with suspected appendicitis. Rates of CT use 1 year before and 1 year after MRI availability are compared.

Levetiracetam in toxic seizures.

Background/objectives: The use of levetiracetam (LEV) in the management of drug-induced seizures has not been systematically investigated. Repetitive and continuous seizures that do not respond to benzodiazepines require second line therapy. Levetiracetam has a unique receptor binding site, rapid absorption, no known cardiac effects at therapeutic doses, and is theoretically a good candidate for use in drug-induced seizures.
