Radiological diagnosis of hepatocellular carcinoma does not preclude biopsy before treatment.

Background & Aims: The diagnosis of hepatocellular carcinoma (HCC) in patients with cirrhosis relies on non-invasive criteria based on international guidelines. The advent of systemic therapies warrants reconsideration of the role of biopsy specimens in the diagnosis of HCC. Accordingly, we investigated the diagnostic performance of the LI-RADS 2018 and the AASLD 2011 criteria.

Peptidylarginine deiminase 4 and ADAMTS13 activity in bacteraemia.

infection is associated with increased levels of neutrophil extracellular traps (NETs) and von Willebrand factor (VWF), and with reduced activity of ADAMTS13 (a disintegrin and metalloproteinase with thrombospondin type 1 motifs, member 13). Peptidylarginine deiminase 4 (PAD4) contributes to NET formation and inactivates ADAMTS13 . The role of PADs in the dynamics of NETs, VWF and ADAMTS13 has not yet been studied.

Management of Bleeding and Hemolysis During Percutaneous Microaxial Flow Pump Support: A Practical Approach.

Percutaneous ventricular assist devices (pVADs) are increasingly being used because of improved experience and availability. The Impella (Abiomed), a percutaneous microaxial, continuous-flow, short-term ventricular assist device, requires meticulous postimplantation management to avoid the 2 most frequent complications, namely, bleeding and hemolysis. A standardized approach to the prevention, detection, and treatment of these complications is mandatory to improve outcomes.

Emicizumab for acquired haemophilia A: A case series.

Background: Emicizumab is approved to prevent bleeding in patients with congenital haemophilia A with or without inhibitors. However, no randomized trials addressed the efficacy of emicizumab in acquired haemophilia A (AHA).

Aims: To report the clinical and biochemical response of emicizumab in AHA.

Impairment of Angiogenesis-Driven Clot Resolution Is a Key Event in the Progression to Chronic Thromboembolic Pulmonary Hypertension: Validation in a Novel Rabbit Model.

Background: Chronic thromboembolic pulmonary hypertension (CTEPH) is a life-threatening condition and rare complication of acute pulmonary embolism. Mechanisms underlying impaired clot resolution and in sustained fibrothrombotic obstruction of the pulmonary arterial bed remain poorly understood. Since defective angiogenesis correlated to defective clot resolution based on observations in surgical material from patients with CTEPH, we aimed to validate its crucial pathogenic role by intrathrombus inhibition of angiogenesis in a novel CTEPH rabbit model.
