The COVID-19 pandemic presents a significant challenge to the global health care system. Implementing timely, accurate, and cost-effective screening approaches is crucial in preventing infections and saving lives by guiding disease management. ⋯ This study developed and validated three machine learning prediction models for COVID-19 mortality based on accessible clinical features. The RF model showed the best performance among the three models. The nine variables identified in the models may warrant further investigation as potential prognostic indicators of severe COVID-19.

Biatrial thrombus is a rare condition that is typically associated with a patent foramen ovale (PFO). ⋯ This is a case of a 75-year-old man with history of heavy alcohol use found down with altered sensorium. He was hypothermic and in atrial fibrillation with rapid ventricular rate and was subsequently found to have a biatrial thrombus with no evidence of PFO. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Biatrial thrombus presents the unique danger of progressing to both pulmonary embolus and acute embolic disease (including stroke); both are life-threatening diagnoses that can be prevented by means of identifying and treating this rare and dangerous condition.
