Analysis of blood coagulation was done on samples of blood collected from ten donors undergoing combined platelet and leukapheresis using the Haemonetics Model 30 Blood Processor. Blood samples were obtained from the donors prior to, during, and following pheresis. Blood was also obtained from the blood-return line after the first collection of leukocytes and platelets, but before it was returned to the donor. Although the citrate anticoagulant was returned to the donor and there were some decreases in the concentrations of fibrinogen, platelets, and factors V and VIII, there were no changes of sufficient degree to suggest that development of a potential bleeding disorder. In addition there was no evidence to suggest that any activation of blood coagulation occurred during the pheresis or that thrombogenic substances were returned to the donors. Combined platelet and leukapheresis using the Haemonetics Model 30 Blood Processor, therefore, do not appear to subject the donor to risks for either bleeding or thrombotic complications.

Background: The usual antithrombotic treatment for symptomatic intracranial atherosclerotic stenosis (ICAS) consists of dual treatment with clopidogrel and aspirin for 90 days followed by aspirin alone but the risk of recurrent stroke remains high up to 12 months. The Comparison of Anticoagulation and anti-Platelet Therapies for Intracranial Vascular Atherostenosis (CAPTIVA) trial was designed to determine whether other combinations of dual antithrombotic therapy are superior to clopidogrel and aspirin.
Methods: CAPTIVA is an ongoing, prospective, double-blinded, three-arm clinical trial at over 100 sites in the United States and Canada that will randomize 1683 high-risk subjects with a symptomatic infarct attributed to 70-99% stenosis of a major intracranial artery to 12 months of treatment with (1) ticagrelor (180 mg loading dose, then 90 mg twice daily), (2) low-dose rivaroxaban (2.

Traumatic hemorrhage and infection are major causes of mortality in wounds caused by battlefield injuries, hospital procedures, and traffic accidents. Developing a multifunctional nano-drug capable of simultaneously controlling bleeding, preventing infection, and promoting wound healing is critical. This study aimed to design and evaluate a nanoparticle-based solution to address these challenges effectively.

: Autologous platelet-rich plasma (PRP) transfusions are a relatively new treatment method used in different fields of medicine, including the field of reproductive medicine. One of the applications of these concentrated platelet infusions is the treatment of endometrial receptivity, which is a key factor for embryo implantation. There are implications that PRP infusions can lead to increased endometrial thickness, endometrial receptivity, and significantly elevated clinical pregnancy rates.

Cartilage repair remains a critical challenge in orthopaedic medicine due to the tissue's limited self-healing ability, contributing to degenerative joint conditions such as osteoarthritis (OA). In response, regenerative medicine has developed advanced therapeutic strategies, including cell-based therapies, gene editing, and bioengineered scaffolds, to promote cartilage regeneration and restore joint function. This narrative review aims to explore the latest developments in cartilage repair techniques, focusing on mesenchymal stem cell (MSC) therapy, gene-based interventions, and biomaterial innovations.

Acute myeloid leukemia (AML) is an aggressive cancer with variable treatment responses. While clinical factors such as age and genetic mutations contribute to prognosis, recent studies suggest that CT attenuation scores may also predict treatment outcomes. This study aims to develop a nomogram combining clinical and CT-based factors to predict treatment response and guide personalized therapy for AML patients.
