Multicenter Study Clinical Trial
Predictors of Successful Weaning from Veno-Arterial Extracorporeal Membrane Oxygenation After Coronary Revascularization for Acute Myocardial Infarction Complicated by Cardiac Arrest: A Retrospective Multicenter Study.
While veno-arterial extracorporeal membrane oxygenation (VA-ECMO) has been utilized to resuscitate and stabilize hemodynamics in patients of acute myocardial infarction (AMI) complicated by cardiac arrest (CA), it is essential to predict the possibility of weaning from ECMO to determine further strategies, including use of ventricular assist device. We aimed to determine predictors of successful weaning from VA-ECMO in the early phase of ECMO treatment. ⋯ Successful weaning from VA-ECMO was predicted by post-PCI TIMI flow grade, MAP at 4 h, and serum lactate at 24 h after VA-ECMO initiation in patients of AMI complicated by CA. Furthermore, in patients who failed to wean from ECMO, LVEF did not recover within 48 h. In such patients, adjunctive use of other circulatory mechanical devices must be considered.

Prognostic Value of Tissue Oxygen Saturation Using a Vascular Occlusion Test in Patients in the Early Phase of Multiorgan Dysfunction Syndrome.
Multiple organ dysfunction syndrome (MODS) is a common disease pattern in intensive care units which is associated with an increased mortality. The aim of this study was to investigate whether a near-infrared spectroscopy (NIRS)-based noninvasive ischemia-reperfusion test (vascular occlusion test) using the parameter of tissue oxygen saturation (StO2) contains prognostic information for patients in the early phase of MODS. ⋯ Impaired values of the VOT-parameters OS and RS are associated with an increased 28-day mortality in patients in the early phase of MODS.

We analyzed the Nationwide Registry database on sepsis to examine the effects of an anticoagulation therapy, especially with rh-thrombomodulin (rh-TM) and/or antithrombin (AT) III agent, in septic disseminated intravascular coagulation (DIC) patients. In 3,193 patients enrolled after the exclusion, we investigated the association with in-hospital mortality using Cox proportional hazards models. DIC was diagnosed using the Japanese Association of Acute Medicine (JAAM) and the International Society of Thrombosis and Hemostasis (ISTH) criteria. ⋯ Septic DIC patients were divided into 3 groups: Group 1, no anticoagulation therapy for DIC; Group 2, received rh-TM and/or AT III; and Group 3, received only "other anticoagulants." In JAAM DIC patients, Group 2 did not show an independent association with a reduced risk of in-hospital mortality (hazard ratio [HR]: 0.86; 95% confidence interval [CI]: 0.73-1.01]) as compared with Group 1. However, in ISTH DIC patients, Group 2 showed an inverse association with the risk of in-hospital mortality (HR 0.74; 95% CI: 0.60-0.92) as compared with Group 1, but the same was not true for Group 3 (HR 0.73; 95% CI: 0.47-1.14). The present results support previous findings of the beneficial effects of anticoagulation therapies in septic DIC, also expands the importance of using rh-TM and/or AT agent for septic overt DIC.

Angiopoietin Level Trajectories in Toddlers with Severe Sepsis and Septic Shock and Their Effect on Capillary Endothelium.
Angiopoietins are postulated diagnostic biomarkers in children and adults with severe sepsis and septic shock. The diagnostic value of angiopoietins in children less than 5 years old has not been established, nor has their effect on permeability in the capillary microvasculature. We aim to determine if levels of angiopoietin-1 or -2 (angpt-1, -2) are diagnostic for severe sepsis/shock in young children and whether they affect the permeability of cultured human dermal microvascular endothelial cells (HDMEC). ⋯ Angpt-2 levels and the angpt-2/1 ratio are appropriate diagnostic biomarkers of severe sepsis/septic shock in children less than 5 years old. Neither angpt-1 nor -2 affects basal HDMEC permeability alone or modulates TNF induced capillary leak.

Teg Lysis Shutdown Represents Coagulopathy in Bleeding Trauma Patients: Analysis of the Proppr Cohort.
Thrombelastography (TEG) fibrinolysis shutdown after trauma is associated with increased mortality due to hypercoagulability-associated organ failure. However, a lack of mechanistic data has precluded the development of novel interventions to treat shutdown. ⋯ Low TEG LY30 does not reflect shutdown of enzymatic fibrinolysis with hypercoagulability, but rather a coagulopathic state of moderate fibrinolysis with fibrinogen consumption and platelet dysfunction that is associated with poor outcomes.
