Whole blood thrombin generation hypercoagulable profile in a patient with hemolytic crisis due to paroxysmal nocturnal hemoglobinuria: a case report
No full textParoxysmal nocturnal hemoglobinuria (PNH) is a rare hematological disorder characterized by intravascular hemolysis, bone marrow failure, and increased thrombotic risk. Previous studies using plasma thrombin generation tests in PNH patients yielded conflicting results. Given the central role of cellular blood components in PNH, we hypothesized that whole blood thrombin generation (WB-TG) may provide a more comprehensive assessment of patients' coagulation profile. We report the case of a 25-year-old woman with PNH and admitted to Padova University Hospital for hemolytic crisis following an influenza A virus infection. WB-TG performed upon admission revealed a hypercoagulable profile vs. healthy controls. The patient was immediately initiated on corticosteroids with good response (i.e., hemoglobin values) and subsequent resolution of hemolysis within ten days. Antithrombotic prophylaxis was administered and no thrombotic events occurred. WB-TG may be a valuable tool in the clinical management of PNH, particularly for the early identification of hypercoagulability and tailoring anticoagulant regimens

Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
