AI Article Synopsis
- As the population ages, physicians face challenges with patients on antiplatelet medications who require urgent neurosurgeries, leading to the need for better assessments of platelet activity.
- The Multiplate® device was tested on 21 patients with a history of antiplatelet use, successfully providing results in under 15 minutes and indicating that certain patients had reduced platelet activity even when on aspirin.
- The device showed promise in evaluating treatment effectiveness by demonstrating significant increases in platelet activity after administering haemostatic measures, suggesting it could enhance care for patients needing urgent neurosurgical intervention.
Article Abstract
Objective: As the population ages, physicians encounter a growing number of patients who are treated with antiplatelet agents and present with severe conditions requiring urgent neurosurgical therapy. Standard laboratory investigations are insufficient to evaluate platelet activity and furthermore, it is difficult to evaluate effects of haemostatic measures on platelet function. In this article we report our initial experiences with the point-of-care device Multiplate® for assessment of platelet activity in neurosurgical emergencies on patients with a reported intake of antiplatelet medication.
Methods: Multiplate® assessment of antiplatelet activity was carried out in 21 non-consecutive patients with a reported intake of antiplatelet medication (aspirin: n=21, clopidogrel: n=3, ticragrelor: n=1) and urgent admission to our hospital because of conditions such as intracranial haemorrhage requiring urgent neurosurgical therapy. Analysis was repeated in order to evaluate the effectiveness of haemostatic drugs and platelet concentrate transfusion on platelet activity in six patients.
Results: No technical difficulties occurred and in all cases, results were obtained within 15 min. On admission, patients' arachidonic acid induced platelet activity was reduced by 44.4±33.5% (range: -79.7% to +44.3%) compared to the lower reference limit. Two patients had a normal platelet activity despite a reported intake of aspirin. Haemostatic measures significantly increased arachidonic acid induced platelet activity by 100±66% (p<0.005).
Conclusion: The Multiplate® device allowed rapid assessment of antiplatelet agent activity and evaluation of haemostatic measures on platelet activity. Further studies with larger patient numbers are needed, but this device may represent a valuable tool to improve treatment modalities in patients treated with antiplatelet medication and conditions requiring urgent neurosurgical therapy.

Introduction: Elbow ailments are common, but conventional treatment modalities have shortcomings, offering only interim pain relief rather than targeting the underlying pathophysiology. The last two decades have seen a marked increase in the use of autologous peripheral blood-derived orthobiologics (APBOs), such as platelet-rich plasma (PRP), to manage elbow disorders. Platelet-rich plasma (PRP) is the most widely used APBO, but its efficacy remains debatable.

Myeloproliferative neoplasms (MPNs) are clonal hematopoietic stem cell disorders commonly characterized by excessive production of blood cell lineages. The JAK2 V617F mutation plays a crucial role in the pathogenesis of these conditions, often leading to thrombotic complications. Here, we present the case of a 21-year-old man who presented with acute abdominal pain and was found to have portal vein thrombosis with splenomegaly.

Quinoline is a highly privileged scaffold with significant pharmacological potential. Introducing a carbonyl group into the quinoline ring generates a quinolone ring, which exhibits promising biological properties. Incorporating a carboxamide linkage at different positions within the quinoline and quinolone frameworks has proven an effective strategy for enhancing pharmacological properties, particularly anticancer potency.
