Neural and Cognitive Consequences of COVID-19 Survival
Recruiting
The novel coronavirus SARS-CoV-2 infection, COVID, continues to rage throughout the world with 115,000,000 confirmed cases and over 2,500,000 deaths (as of Mar 3, 2021). This translates to millions of people surviving COVID19 infection. While the lungs are ground zero, COVID tears through organ systems from brain to blood vessels. We are now beginning to see people recover but complain of ongoing problems, including lingering cognitive problems, depression, and anxiety. We have brought together... Read More

COVID-19 Outcome Prediction Algorithm
Recruiting
Severe acute respiratory syndrome coronavirus 2-mediated coronavirus disease (COVID-19) is an evolutionarily unprecedented natural experiment that causes major changes to the host immune system. We propose to develop a test that accurately predicts short- and long-term (within one-year) outcomes in hospitalized COVID-19 patients broadly reflecting US demographics who are at increased risk of adverse outcomes from COVID-19 using both clinical and molecular data. We will enroll patients from a hos... Read More
