In October, the CDC reported on the condition and named it multisystem inflammatory syndrome in adults (MIS-A). Questions have been raised regarding possible relationships between MIS-C and certain severe manifestations of COVID-19 in adults.Childrens neurological symptoms, as studied in London in mid-2020, often involved "both the central and peripheral nervous systems," according to a report by the American Academy of Neurology released on 13 April 2021.The official MIS-C Awareness Week is in December - Created by the non-profit organization CircumSTANCE. CircumSTANCE created the first ever Multisystem Inflammatory Syndrome Awareness campaign in 2020, they also created the official "MIS-C Awareness Ribbon". For more information on MIS-C awareness and advocacy, please visit their web site and social media pages. www.abovecircumstances.org

A stress ulcer is a single or multiple mucosal defect which can become complicated by upper gastrointestinal bleeding or physiologic stress. Ordinary peptic ulcers are found commonly in the gastric antrum and the duodenum whereas stress ulcers are found commonly in fundic mucosa and can be located anywhere within the stomach and proximal duodenum. Signs and symptoms
Stress ulcers, as defined by overt bleeding and hemodynamic instability, decreased hemoglobin, and/or need for transfusion, were seen in 1.5% of patients in the 2252 patients in the Canadian Critical Care Trials group study. People with stress ulcers have a longer ICU length of stay (up to 8 days) and a higher mortality (up to 4 fold) than patients who do not have stress ulceration and bleeding. While the bleeding and transfusions associated with the stress ulcerations contribute to the increased mortality, the contribution of factors like low blood pressure, sepsis, and respiratory failure to the mortality independently of the stress ulceration cannot be ignored. Risk factors
Risk factors for stress ulcer formation that have been identified are numerous and varied. However, two landmark studies and one position paper exist that addresses the topic of risk factors for stress ulcer formation:

Non-critically ill medical patients with 2 or more of the following: respiratory failure, sepsis, heart failure, hepatic encephalopathy, jaundice, kidney failure, stroke, hypertension, previous gastrointestinal disease and treatment with corticosteroids, NSAIDS, heparin, or warfarin. In surgical critically ill patients, only those patients who are on a mechanical ventilator for more than 48 hours and/or those with a coagulopathy.
