Activated clotting time value as an independent predictor of postoperative bleeding and transfusion.

Objectives: Activated clotting time (ACT) is commonly used to monitor anticoagulation during cardiac surgeries. Final ACT values may be essential to predict postoperative bleeding and transfusions, although ideal values remain unknown. Our aim was to evaluate the utility of ACT as a predictor of postoperative bleeding and transfusion use.

Anticoagulation Management in V-V ECMO Patients: A Multidisciplinary Pragmatic Protocol.

(1) Background: Extracorporeal membrane oxygenation (ECMO) is a complex procedure affecting both the risk of thrombosis and bleeding. High-quality data to personalize anticoagulation management in ECMO are lacking, resulting in a high variability in practice among centers. For this reason, we review coagulation methods and monitoring and share a pragmatic proposal of coagulation management, as performed in our high-volume ECMO Referral Centre; (2) Methods: We revised the anticoagulation options and monitoring methods available for coagulation management in ECMO through PubMed search based on words including "anticoagulation," "coagulation assays," "ECMO," "ELSO," and "ISTH"; (3) Results: Actual revision of the literature was described as our routine practice regarding ECMO anticoagulation and monitoring; (4) Conclusions: No coagulation test is exclusively predictive of bleeding or thrombotic risk in patients undergoing ECMO support.

Full-Dose Azacitidine in 5 Days Versus 7 Days With a Weekend Break in Myelodysplastic Syndromes: A Retrospective Cohort Study.

Introduction: Apart from transplantation, only azacitidine demonstrated a survival benefit in a phase III study in higher-risk myelodysplastic syndromes (MDS). The approved regimen is 75 mg/m/day for 7 consecutive days, imposing a logistic challenge for outpatient weekend administration. Schedules with 5 days and 7 days with a weekend break (5 + 2) have been used for convenience despite the lack of strong scientific support.

COVID-19-associated Coagulopathy Characterization using Rotational Thromboelastometry in a Prospective, Observational Cohort Study: The HemoCoV Study.

Introduction: COVID-19-associated coagulopathy includes systemic and endothelial inflammation with coagulation dysregulation related to immunothrombosis. The aim of this study was to characterize this complication of SARS-CoV-2 infection in patients with moderate to severe COVID-19.

Methods: An open-label, prospective observational study conducted in patients with COVID-19 moderate to severe acute respiratory failure admitted to an intensive care unit (ICU).

Hemophagocytic Lymphohistiocytosis Secondary to Chronic Lymphocytic Leukemia Progression.

Hemophagocytic lymphohistiocytosis (HLH) is an acute, rare systemic hyperinflammatory disorder caused by a dysregulated immune cell function and massive cytokine release, often leading to multiple organ involvement and failure. Fever, hepatosplenomegaly, cytopenia, elevated liver enzymes, hypertriglyceridemia, and hyperferritinemia are the hallmarks of the disease. Its primary (genetic) form is typically observed in pediatric patients and its secondary, acquired form is seen in adult patients with an underlying autoimmune, malignant, or infectious disease.

Therapeutic Options in Refractory Evans Syndrome: A Case Report.

Evans syndrome is a rare autoimmune disease, characterized by at least two immune cytopenias, most frequently anemia and thrombocytopenia and rarely immune neutropenia. It has a variable clinical presentation and is rarely diagnosed in adults. It can be idiopathic or secondary to lymphoproliferative disease, infections, autoimmune diseases, drugs, and immunodeficiencies in about 50% of cases.
