Coronavirus disease 2019 (COVID-19) is known to cause multi-organ dysfunction 1 – 3 during acute infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), with some patients experiencing prolonged symptoms, termed post-acute sequelae of SARS-CoV-2 (refs. 4 , 5 ). However, the burden of infection outside the respiratory tract and time to viral clearance are not well characterized, particularly in the brain 3 , 6 – 14 . Here we carried out complete autopsies on 44 patients who died with COVID-19, with extensive sampling of the central nervous system in 11 of these patients, to map and quantify the distribution, replication and cell-type specificity of SARS-CoV-2 across the human body, including the brain, from acute infection to more than seven months following symptom onset. We show that SARS-CoV-2 is widely distributed, predominantly among patients who died with severe COVID-19, and that virus replication is present in multiple respiratory and non-respiratory tissues, including the brain, early in infection. Further, we detected persistent SARS-CoV-2 RNA in multiple anatomic sites, including throughout the brain, as late as 230 days following symptom onset in one case. Despite extensive distribution of SARS-CoV-2 RNA throughout the body, we observed little evidence of inflammation or direct viral cytopathology outside the respiratory tract. Our data indicate that in some patients SARS-CoV-2 can cause systemic infection and persist in the body for months.

The selective estrogen receptor modulator tamoxifen inhibits the development of AAAs in male rats in association with an up-regulation of catalase and inhibition of aortic wall neutrophil infiltration.

ECMO is the next step in the algorithm for management of severe respiratory failure unresponsive to conventional care.

Patients supported with venovenous extracorporeal membrane oxygenation are at risk for intra-abdominal hypertension and abdominal compartment syndrome. Flow through the return cannula may be compromised in these patients, resulting in inadequate support and end-organ malperfusion. Early decompressive laparotomy can mitigate these complications and potentially improve outcomes. Here we review a series of nine patients undergoing early decompressive laparotomy for abdominal compartment syndrome at a single institution and propose an algorithmic approach to the management of these patients.

Mechanically assisted single ventricle parallel circulation can be established in a single ventricle animal model. This strategy could potentially provide MCS of a single ventricle circulation. Studies with longer duration of support are required to assess adequacy of support and long-term sustainability.
