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…
Second trimester uterine arteries pulsatility index is a function of placental pathology and provides insights on stillbirth aetiology: A multicenter matched case-control study
Introduction: The aim of this study was to investigate the relationships between maternal vascular malperfusions (MVM) and second trimester uterine arteries pulsatility index (UtA-PI) in cases of stillbirth (SB), compared to live-birth (LB) matched controls. Methods: This was a multicentre, observational, matched case-control study performed at five referral maternity centres over a 4-year period including SB and LB control pregnancies at high-risk for preeclampsia (PE) and/or fetal growth restriction (FGR), matched and stratified for UtA-PI MoM quartiles values of the SB cases. Logistic regression was used to assess the rates of each MVM finding, within each increasing MoM quartile subcate…
