Maximal disease severity of COVID-19 as defined by the Society for Maternal and Fetal Medicine (SMFM) via data-linkage to medical records

- Asymptomatic or presymptomatic disease or presumptive infection is defined as a positive COVID-19 test result with no symptoms.

- Mild disease is defined as flu-like symptoms, such as fever, cough, myalgias, and anosmia without dyspnea, shortness of breath, or abnormal chest imaging.

- Moderate disease is defined by evidence of lower respiratory tract disease with clinical assessment (dyspnea, pneumonia on imaging, abnormal blood gas results, refractory fever of 39.0 °C /102.2 °F or greater not alleviated with acetaminophen) while maintaining an oxygen saturation of greater than or equal to 94% on room air at sea level
.
- Severe disease is defined by a respiratory rate greater than 30 breaths per minute (bpm), hypoxia with oxygen saturation less than 94%, a ratio of arterial partial pressure of oxygen to fraction of inspired oxygen of less than 300, or greater than 50% lung involvement on imaging.

- Critical disease is defined as multi-organ failure or dysfunction, shock, or respiratory failure requiring mechanical ventilation or high-flow nasal cannula.

- Refractory hypoxemia is defined as persistent, inadequate oxygenation and/or ventilation despite substantial and appropriate measures to optimize it and represents a further escalation of severity on the spectrum of disease.

Summary
Brief summary
CO-Sprout clinical trial will investigate whether broccoli sprout powder capsules given to pregnant women infected with SARS-CoV-2 (COVID-19) can help reduce the duration of COVID-19 associated symptoms. Additional outcomes measured will include hospital admissions, maternal respiratory outcomes, obstetric and birthing outcomes, as well as neonatal outcomes. It is hoped that providing pregnant women with this natural supplement during COVID-19 infection, will help reduce the levels of inflammation and improve their symptoms hopefully leading to reduced need for hospital and ICU admissions. Broccoli sprout powder contains the naturally occurring phytonutrient sulforaphane which is hoped to improve maternal and neonatal outcomes during pregnancy from infection with the SARS-CoV-2 virus.
