Thromboelastography to Detect Hypercoagulability and Reduced Fibrinolysis in Coronavirus Disease 2019 Acute Respiratory Distress Syndrome Patients.

Objectives: Microvascular thrombosis contributes to acute respiratory distress syndrome pathophysiology and has been demonstrated in coronavirus disease 2019-associated acute respiratory distress syndrome. Clinical laboratory measurements of coagulation and disseminated intravascular coagulation, such as coagulation factor function, platelet count, and fibrinogen, may not fully reflect the extent of microvascular thrombosis present in these patients. We investigated thromboelastography in patients with coronavirus disease 2019-associated acute respiratory distress syndrome with the objective of characterizing suspected coagulopathy and impaired fibrinolysis.

New developments in the management of moderate-to-severe hemophilia B.

Hemophilia B is an X-linked genetic deficiency of coagulation factor IX (FIX) activity associated with recurrent deep tissue and joint bleeding that may lead to long-term disability. FIX replacement therapy using plasma-derived protein or recombinant protein has significantly reduced bleeding and disability from hemophilia B, particularly when used in a prophylactic fashion. Although modern factor replacement has excellent efficacy and safety, barriers to the broader use of prophylaxis remain, including the need for intravenous (IV) access, frequent dosing, variability in individual pharmacokinetics, and cost.

Mantle Cell Lymphoma: First-line Therapy in Patients Not Eligible for Stem Cell Transplantation.

Mantle cell lymphoma is a distinct subtype of non-Hodgkin's lymphoma, which has historically been associated with a poor prognosis. It is now recognized as a heterogeneous disease with variable biologic and clinical behavior. Treatment paradigms have evolved along two lines.
