Occurrence of Centrouropoda almerodai and Uroobovella marginata (Acari: Uropodina) phoretic on the Red Palm Weevil in Malta

The unwanted introduction of the Red Palm Weevil (RPW) coincides with the spread in Malta of two species of Uropodid mites associated with this weevil. Usually, adult RPW carry phoretic forms of C. almerodai which are attached to the underside of elytra, and U. marginata that prefers exposed surfaces of sternum, pygidium, head and legs. These mites use adult RPW to abandon dead palms and to colonize newly infested host-plants. Their role as plant pests is however negligible. Even the plant pathogen conidia, Curvularia which are carried by the mites, seem unable to germinate in palms under laboratory conditions. Both Centrouropoda almerodai and Uroobovella marginata are established in the Ma…

SARS-CoV-2 infection and venous thromboembolism after surgery: an international prospective cohort study

SARS-CoV-2 has been associated with an increased rate of venous thromboembolism in critically ill patients. Since surgical patients are already at higher risk of venous thromboembolism than general populations, this study aimed to determine if patients with peri-operative or prior SARS-CoV-2 were at further increased risk of venous thromboembolism. We conducted a planned sub-study and analysis from an international, multicentre, prospective cohort study of elective and emergency patients undergoing surgery during October 2020. Patients from all surgical specialties were included. The primary outcome measure was venous thromboembolism (pulmonary embolism or deep vein thrombosis) within 30 da…
