Summary: Platelets, derived from megakaryocytes, play a vital role in hemostasis and can be used as a platform for disease-targeted drug delivery. Platelet defects can lead to bleeding complications, while platelet-inspired technologies have the potential to improve therapeutic efficacy.

Summary: Selatogrel, a potent and reversible antagonist of the P2Y12 receptor, exhibited strong anti-thrombotic effects in animal models by inhibiting platelet function, preventing blood flow decrease, and dissolving pre-formed platelet thrombi without disrupting hemostatic seals. The findings suggest a potential dual benefit of selatogrel in patients with acute thrombosis.

Summary: This pilot study demonstrated that patients with MGUS, SM and MM have increased platelet reactivity and prothrombotic potential, which is further exacerbated by treatment with Lenalidomide.

Summary: This study aimed to establish a shear-dependent platelet function defect in patients with prolonged platelet function analyser (PFA) closure time without evidence of von Willebrand disease or impaired platelet aggregation. Microfluidic analysis showed significantly lower platelet adhesion and thrombus formation parameters in these patients compared to healthy volunteers. Principal components analysis indicated von Willebrand factor as the primary explanation for PFA prolongation, whereas conventional platelet aggregation explained the reduced thrombus parameters under shear. This suggests a shear-dependent platelet function defect, not detected by static conventional haemostatic tests.

Summary: 1,8-cineole has shown inhibitory effects on platelet activation, thrombus formation, and hemostasis, affecting platelet signaling pathways, granule secretion, and intracellular calcium mobilization. It may act as a potential therapeutic agent to control unwarranted platelet reactivity under various pathophysiological settings.

Summary: Through real-time intravital microscopy in mice, it was found that compared to clopidogrel and ticagrelor, Selatogrel has fewer platelet thrombus formations, better stability of hemostatic seals, and does not interfere with endothelial activation, neutrophil function, and fibrin-mediated stabilization of hemostatic seals.

Summary: Arachidonic acid is a common omega-6 polyunsaturated fatty acid that can produce various biologically active substances. It exists in esterified form in cell membrane phospholipids and is released through the actions of phospholipases, affecting important physiological processes such as blood coagulation and vascular functions.

Summary: A novel series of TGX-221 analogues were synthesized by replacing the 4H-pyrido[1,2-a] pyrimidin-4-one scaffold with a 4H-benzo[e][1,3]oxazin-4-one scaffold. The analogues with an -CH(CH3) NH- linker demonstrated comparable activity to TGX-221 analogues, supported by comparative structure-activity relationship analysis. The analogues containing an -CH(CH3)O- linker exhibited lower activity but still displayed useful structure-activity relationship, including a preferred o-methyl substitution.

Summary: This study aimed to assess the incidence of VTE and bleeding within 30 days following major surgery in patients with ovarian cancer and evaluate the association between VTE and thromboprophylaxis duration. The study found that the cumulative incidence of VTE was considerable in patients with ovarian cancer following major surgery, but extended thromboprophylaxis did not significantly lower the risk of VTE. Overall, the importance of this article is 7 out of 10.

Summary: This review discusses the relationship between trace metals and the hemostatic system. It highlights the importance of maintaining appropriate levels of trace metals and addresses the negative impact of poor diet habits and pollution. The implementation of food and nutrient support is crucial in improving the quality of life, especially in developing countries, and preventing long-term negative outcomes.

Summary: The evaluation of haemostasis is particularly challenging in neonates due to their limited blood volume. The Calibrated Automated Thrombogram (CAT) has successfully elucidated several differences between haemostatic mechanisms in premature and term neonates compared with adults. However, the lack of evidence of CAT as an accurate predictor of neonatal bleeding, blood volume required, and the absence of an evidence-based treatment algorithm for abnormal CAT results limit its current application as a bedside clinical tool for the evaluation of sick neonates.

Summary: In this study, we investigated the adhesive properties of circulating plasma-derived and platelet-derived microvesicles (MVs) and their potential role in thrombus growth. The results showed that both types of MVs weakly bound fibrinogen but did not stably adhere to immobilized fibrinogen. Moreover, the presence of these MVs did not significantly affect thrombus formation. Therefore, MVs present in the plasma of healthy individuals are unlikely to directly contribute to thrombus formation under arterial flow conditions.

Summary: This study analyzed and evaluated leukemia-associated coagulopathy in newly diagnosed pediatric leukemia patients using CCTs and ROTEM. The results showed that fibrinogen and platelets played a significant role in causing coagulopathies in this population. This suggests the utility of using CCTs and ROTEM in the pediatric population to evaluate hemostatic function and guide blood product replacement.

Summary: Thrombotic disease may be underdiagnosed in microgravity conditions, and the underlying factors are still poorly understood. A case of internal jugular vein thrombosis was recently diagnosed in a low-risk female astronaut, and six out of ten additional crew members showed risk factors for jugular venous flow. Observations in space and studies on Earth suggest that microgravity affects blood flow, coagulation, and vascular function.

Summary: This study found that no single PROM covered all aspects considered important by PE patients. PROMs recommended in the ICHOM core set covered most aspects, but worrisome thoughts, hypervigilance around symptoms, and uncertainty of illness were not covered.

Summary: The incidence of cancer-associated stroke has increased with the prolonged survival times of cancer patients. In this study, the researchers focused on the driver gene KRAS and found that KRAS mutations exacerbated neurological deficits after stroke and promoted tumor growth. They also identified the upregulation of pro-inflammatory responses and the promotion of STAT3 phosphorylation in mice with KRAS mutations. Additionally, the researchers found that colorectal cancer patients with stroke onset within 3 months after cancer diagnosis had a worse prognosis.

Summary: This study investigated the gut microbiota metabolites and cytokines, chemokines, and growth factors in patients with ITP and found their association with treatment responsiveness. The findings suggest that imbalanced secretion of cyto(chemo)kins/growth factors and inadequate levels of TMAO are characteristic of patients with ITP.

Summary: This study evaluated the safety of fixed-dose heparin titration boluses in underweight patients with VTE. The results showed that although underweight patients required more frequent holding of heparin, there was no significant increase in bleeding risk.
