[Paper Published] Conceptual Framework Reorganizing Obstetric DIC Pathophysiology Published in Thrombosis Research

### Overview

Medical Education Co., Ltd. (Suginami-ku, Tokyo; CEO: Takashi Ochiai) is pleased to announce that a research paper titled "Toward an endothelium-centered framework for obstetric disseminated intravascular coagulation: Harmonizing pathophysiology, diagnosis, and treatment," authored by Dr. Ryo Kamidani and colleagues at Gifu University Graduate School of Medicine, has been published in the academic journal *Thrombosis Research*.

This review paper reorganizes the pathophysiology of obstetric Disseminated Intravascular Coagulation (DIC) from a new perspective focusing on vascular endothelial injury. MEDICAL FIG., operated by Medical Education Co., Ltd., was responsible for producing the conceptual figure (Figure) included in this paper.

### Figure Used in This Research

The conceptual figure reorganizes obstetric DIC pathophysiology from two perspectives: "placental/amniotic fluid-derived hemostatic load" and "vascular endothelial injury." It illustrates how multiple causes converge into a common endothelial pathology, leading to final clinical symptoms.

### Role of the Figure in This Research

In this study, various diseases causing obstetric DIC are organized by etiology. It presents a pathological framework where each cause leads to hypercoagulation, hyperfibrinolysis, and microcirculatory disturbances through vascular endothelial injury (endothelial glycocalyx damage).
The produced Figure was designed as a bird's-eye view conceptual diagram to reorganize obstetric DIC pathophysiology—which cannot be fully explained by the traditional "bleeding type/thrombotic type" dichotomy—around the core factors of hemostatic load and endothelial damage.

### Key Considerations in Figure Production

The Figure was created as an introductory conceptual diagram for the review paper. Information is organized in a three-stage structure: etiology, pathogenesis, and clinical symptoms, reconstructed as a flowchart where multiple causes converge into common endothelial pathology. Special care was taken in the illustration of the endothelial glycocalyx to ensure expressions that minimize interpretational differences among experts.
