There are many unique issues that may make a pathologist's consultation helpful in hemostasis testing. Besides the rapidly expanding knowledge of both bleeding and thrombotic disorders and a wide test menu, hemostasis testing is very sensitive to preanalytical issues (hemolysis, fill volume, time, temperature, storage conditions) and the interference of many commonly prescribed drugs. The pathologist can serve an important role in the evaluation of a patient for a bleeding or thrombotic disorder. Using defined algorithms, hemostasis testing can proceed in a logical fashion and be reported using patient-specific comments that take into account clinical history and medication therapy. This approach can improve the diagnostic process, preventing misdiagnoses and leading to a decreased time to diagnosis and an improved utilization of laboratory resources.

Changes in platelet maturity and reactivity following acute ST-segment elevation myocardial infarction.
Res Pract Thromb Haemost
January 2025
Department of Cardiology, Aarhus University Hospital, Aarhus, Denmark.
Background: Reduced effect of antiplatelet therapy has been reported in patients with ST-segment elevation myocardial infarction (STEMI). This could partly be explained by an increase of highly reactive immature platelets.
Objectives: To investigate changes in platelet maturity and reactivity after acute STEMI.
Vitamin K Antagonist Use and Level of Anticoagulation Control Among Patients at a Tertiary Hospital in Northern Tanzania.

Department of Internal Medicine, Kilimanjaro Christian Medical University College, Moshi, Tanzania.
Background: Vitamin K antagonists (VKA) continue to be the principal anticoagulants for both the treatment and prevention of venous thromboembolism. The use of VKA often requires regular monitoring to avoid over-anticoagulation and prevent thromboembolic complications. The aim was to determine the indication for VKA use and factors associated with suboptimal anticoagulation control among patients in northern Tanzania.

Division of Plastic and Reconstructive Surgery, Department of Surgery, Icahn School of Medicine at Mount Sinai, 10 Union Square East, Suite 2L, New York, 10003, USA.
Purpose: Breast reduction (BR) involves a large surface area of manipulated tissue, increasing the risk of postoperative hematoma. Pulse irrigation (PI) uses a device to deliver intermittent pressurized irrigant intraoperatively. This study aims to evaluate whether the use of PI is associated with reduced incidence of postoperative hematoma after BR.

ACS Appl Bio Mater
January 2025
Technical Institute of Physics and Chemistry, Chinese Academy of Sciences, Beijing 100190, PR China.
Chitosan is generally considered to be a procoagulant effect, which may cause adverse phenomena such as blood clotting when used in small-diameter vascular grafts. However, it also shows good biocompatibility and anti-inflammatory properties, which can facilitate vascular reconstruction. Therefore, it is significant to transition the effect of chitosan from coagulation promotion to antiplatelet while still harnessing its bioactivity.

Department of Hematology, Ankara University School of Medicine, Ankara, Turkey.
Despite numerous reports on the procoagulant activities of G-CSF, the effect of plerixafor on the hemostatic system is not clearly understood. This study aims to evaluate the effects of plerixafor on the hemostatic system when used for autologous stem cell mobilization (ASCM) for poor mobilizers (PM) with lymphoma and multiple myeloma. Patients who were performed ASCM with plerixafor in combination with GCSF were prospectively enrolled.
