Corona Virus Disease 2019 in situ arterial and venous thrombosis in critically ill patients: a case series

Background Corona Virus Disease 2019 (COVID-19) pneumonitis associated with severe respiratory failure carries a high mortality. Coagulopathy has emerged as a significant contributor to thrombotic complications. Case summary We describe two cases of severe COVID-19 pneumonitis refractory to conventional mechanical ventilation and proning position, transferred to our specialist centre for cardiorespiratory failure. Cross-sectional imaging demonstrated concurrent venous and aortic thrombosis with end-organ ischaemic changes. One patient received thrombolysis with a partial response. This could not be offered to the other patient due to a recent haemorrhagic event. Both patients died of multi-organ failure in the hospital. Discussion Concurrent aortic and venous thromboses are rare. This finding in COVID-19 cases, who were both critically ill patients, likely reflects the strongly thrombogenic nature of this illness which ultimately contributed to poor outcomes. The absence of deep vein thrombosis or a potential systemic source of embolism suggests in situ thrombosis. Further, the management of anticoagulation and thrombolysis is challenging in patients where an attendant bleeding risk exists

Open Area, Open Data: Advances in Reflexive Archaeological Practice

This article presents a holistic and reflexive process for archaeological fieldwork from inception to publication. The opportunities afforded by maturing digital techniques allowed fundamental rethinking of field and laboratory practice paradigms. A number of normally unquestioned aspects of archaeological praxis were examined with the goal of reorganising information dynamics. Instead of a series of disparate processes in the field and field laboratory and during study and publication phases, a heterarchically-organised common information framework bonded all aspects of work traditionally only brought together in post-excavation processing, replacing disparate datasets and encompassing ongoing processes such as excavation recording, finds processing and final analyses. Recording uses a common interface based on the iDig iPad app, and analyses use 3D GIS based on comprehensive photogrammetry and an underlying all-encompassing data engine. The development and application of the process are described with reference to the excavations, study and publication of the EBA site of Keros, Cyclades, Greece.Stavros Niarchos Foundation A.G.
