Wada教授の研究室は、心肺停止後の全身虚血再灌流障害やDICに伴う凝固・線溶系の制御異常が、急性肺障害(ALI/ARDS)や多臓器障害症候群(MODS)に与える影響を、血管新生関連因子(sVEGFR2、Ang2)や凝固・線溶系マーカーの動態に基づいて解明しています。特に、SARS-CoV-2感染に伴うコagulopathyや、心肺蘇生後のハイファイブリノリシス状態が臨床予後に及ぼす影響を、分子メカニズムと臨床的バイオマーカーの両面から研究しています。

Angiogenic factors and their soluble receptors, particularly sVEGFR2 and Ang2, are thus considered to be valuable predictive biomarkers in the development of ALI/ARDS associated with critical illness and mortality in ALI/ARDS patients.
Whole-body ischemia and reperfusion due to cardiac arrest and subsequent return of spontaneous circulation constitute post-cardiac arrest syndrome (PCAS), which consists of four syndromes including systemic ischemia/reperfusion responses and post-cardiac arrest brain injury. The major pathophysiologies underlying systemic ischemia/reperfusion responses are systemic inflammatory response syndrome and increased coagulation, leading to disseminated intravascular coagulation (DIC), which clinically
DIC, especially DIC with hyperfibrinolysis, affects the outcome of patients with iTBI. Low blood pressure-induced tissue hypoperfusion does not contribute to hyperfibrinolysis in this type of DIC.
Thromboplasminflammation in coronavirus disease 2019 (COVID-19) coagulopathy consists of angiotensin II (Ang II)-induced coagulopathy, activated factor XII (FXIIa)- and kallikrein, kinin system-enhanced fibrinolysis, and disseminated intravascular coagulation (DIC). All three conditions induce systemic inflammation <i>via</i> each pathomechanism-developed production of inflammatory cytokines. Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) downregulates angiotensin-converting enzyme
A “modular repertoire of contention” denotes prevalent forms of interaction that are used by a variety of actors against a variety of targets for a variety of issues in a variety of locations. Modular repertoires are important in the literature of contentious politics and social movements because of their transferability across different contentious contexts. This study addresses three limitations in the literature. First, discussion about modular repertoires to date has been framed as if some f
The fibrinolytic phenotype of DIC during the early phase of post-CPR more frequently results in SIRS and MODS, especially in patients with hyperfibrinolysis, and affects the outcome of OHCA patients.
We observed a marked imbalance between Ang1 and Ang2 in favor of Ang2 in PCAS patients, and the effect was more prominent in non-survivors. Angiogenic factors and their soluble receptors, particularly Ang2 and Ang2/Ang1, are considered to be valuable predictive biomarkers in the development of organ dysfunction and poor outcomes in PCAS patients.
<b>Background:</b> Traumatic brain injury (TBI)-associated coagulopathy is a widely recognized risk factor for secondary brain damage and contributes to poor clinical outcomes. Various theories, including disseminated intravascular coagulation (DIC), have been proposed regarding its pathomechanisms; no consensus has been reached thus far. This study aimed to elucidate the pathophysiology of TBI-induced coagulopathy by comparing coagulofibrinolytic changes in isolated TBI (iTBI) to those in non-T
Why do citizens demand certain kinds of citizenship rights rather than another in a given context? This article extends the idea of political and cultural opportunities to Mexico's authoritarian context to explore why Mexicans, who had prioritized social rights over other rights, came to emphasize political rights in a context of neoliberalism. In particular, I ask how this transformation from social protests to political protests happened when neither political nor cultural opportunities appear
Trauma patients die from massive bleeding due to disseminated intravascular coagulation (DIC) with a fibrinolytic phenotype in the early phase, which transforms to DIC with a thrombotic phenotype in the late phase of trauma, contributing to the development of multiple organ dysfunction syndrome (MODS) and a consequently poor outcome. This is a sub-analysis of a multicenter prospective descriptive cross-sectional study on DIC to evaluate the effect of a DIC diagnosis on the survival probability a
The systemic thrombin generation accelerated by insufficient antithrombin control leads to the consumption of platelets and coagulation factors associated with hyperfibrin(ogen)olysis. These changes are collectively termed disseminated intravascular coagulation with the fibrinolytic phenotype.
Two phenotypes of disseminated intravascular coagulation (DIC) are systematically reviewed. DIC is classified into thrombotic and fibrinolytic phenotypes characterized by thrombosis and hemorrhage, respectively. Major pathology of DIC with thrombotic phenotype is the activation of coagulation, insufficient anticoagulation with endothelial injury, and plasminogen activator inhibitor-1-mediated inhibition of fibrinolysis, leading to microvascular fibrin thrombosis and organ dysfunction. DIC with f
Abstract Background The development of disseminated intravascular coagulation (DIC) in patients with sepsis has been repeatedly confirmed as a factor associated with poor prognosis. Anticoagulant therapy has been expected to improve sepsis patient outcomes, whereas no randomized controlled trials have demonstrated the survival benefit of anticoagulant therapies in non-specific overall sepsis. Patient selection based on the component of “high disease severity” in addition to “sepsis with DIC” has
The debate about the rise of civil society in Mexico suggests that the processes of political and economic liberalization are multiple and uneven and, thus, have different and contradictory effects on different social groups. This study takes such arguments into account and examines the nature of collective identities and social networks that are more likely to be mobilized in the rising civil society. Who, with what types of social networks and identities, are the active actors in this rising c
