Endothelial Damage in JAK2V617F Myeloproliferative Neoplasms with Splanchnic Vein Thrombosis.

Background:  V617F-mutated myeloproliferative neoplasms (MPN) exhibit abnormal proliferation of bone marrow progenitors and increased risk of thrombosis, specifically in splanchnic veins (SVT). The contribution of the endothelium to the development of the prothrombotic phenotype was explored.

Material And Methods:  Plasma and serum samples from V617F MPN patients with (n=26) or without (n=7) thrombotic debut and different treatments, were obtained (n=33).

Circulating extracellular vesicles and neutrophil extracellular traps contribute to endothelial dysfunction in preeclampsia.

Background: Preeclampsia (PE) is a pregnancy complication characterized by hypertension, proteinuria, endothelial dysfunction, and complement dysregulation. Placenta-derived extracellular vesicles (EVs), necessary in maternal-fetal communication, might contribute to PE pathogenesis. Moreover, neutrophil extracellular traps (NETs) play a pathogenic role in other complement-mediated pathologies, and their contribution in PE remains unexplored.

Increased Platelet Adhesiveness in Patients with Venous Thromboembolic Disease.

 Association between global platelet function and the risk of venous thromboembolic disease (VTE) has been proposed, though the mechanisms do not involve increased platelet aggregation. However, platelet adhesiveness has not been systematically explored in VTE patients.  To evaluate platelet adhesive functions in VTE patients.

Smartphone and tablet use pattern in children up to 5 years old in Spain: a cross-sectional study.

to characterize the smartphones and tablets use pattern in a sample of children up to 5 years old and assess with which variables it is associated. cross-sectional study of 410 parents of children up to 5 years of age. Data were obtained from an online questionnaire.
