Purpose: The aim of the study is to determine if clot distribution in acute pulmonary embolism (PE) correlates with morphometric measurements of right heart function, reflux in inferior vena cava (IVC), and pleuroparenchymal findings.
Materials And Methods: A total of 692 computed tomography pulmonary angiographies with PE were enrolled, and patients were grouped according to clot localization. Parenchymal findings, morphometric measurements of right heart function, and contrast reflux in IVC were noted.
Results: Differences were found between groups for most measurements, and central PE was associated with significantly higher right ventricle (RV) and pulmonary artery diameters, ratio of RV diameter to left ventricle (LV) diameter (RV/LV) ≥ 1, and IVC reflux.
Conclusions: Significant association was present among clot distribution in PE, morphometrics, IVC reflux, and pleuroparenchymal findings.

Background: Antithrombotic medications are essential for the management of abnormal clot formation. However, their availability, pricing, and affordability in Ethiopia, particularly in Addis Ababa, have not been comprehensively studied.
Methods: A cross-sectional study was conducted in Addis Ababa, Ethiopia to assess the availability, pricing, and affordability of essential antithrombotic medicines.

Viscoelastic testing evaluates the formation and lysis of a clot over time, allowing more complete assessment of patient hemostasis in real time, whereas traditional tests, such as prothrombin time and partial thromboplastin time, only measure coagulation factor function. Patient-side viscoelastic coagulation monitors are easy to use, portable, and provide faster turnaround time than commercial laboratories. Viscoelastic testing requires only 0.

Background And Objectives: The liver, a vital metabolic organ, is always susceptible to various diseases that ultimately lead to fibrosis, cirrhosis, acute liver failure, chronic liver failure, and even cancer. Optimal and specific medicine delivery in various diseases, hepatectomy, shunt placement, and other surgical interventions to reduce liver damage, transplantation, optimal preservation, and revival of the donated organ all rely on a complete understanding of perfusion and mass transfer in the liver. This study aims to simulate the computational fluid dynamics of perfusion and the temporal-spatial distribution of a medicine in a healthy liver to evaluate the hemodynamic characteristics of flow and medicine transport with the purpose of more effective liver treatment.

Introduction: Since mechanical thrombectomy has allowed ischaemic stroke thrombus retrieval, the exhaustive study of this material has enabled better understanding of the potential physiopathological processes involved in thrombus formation.
Development: Thrombotic pathways involved in the different vascular beds share common mechanisms, causing difficulties in the identification of specific patterns associated with stroke aetiology. However, other factors such as clot formation time, associated inflammatory status, or activation of additional immune and coagulation pathways (neutrophil extracellular trap [NET] delivery, platelet aggregation, endothelial activation, and von Willebrand Factor release) have been described as determinants in thrombus characteristics.

Purpose And Methods: This prospective study aims to diagnose the etiology of non-focalized fever lasting between 5 and 28 days in the islands of La Palma and El Hierro (Canary Islands, Spain) during 2021, using serology and PCR.
Results: The etiological profile described in this study aligns with that of fever of intermediate duration (FID), with zoonoses being the primary cause. Murine typhus (MT) is identified as the leading cause, followed by Q fever (QF).
