Plasmas From Patients With Burn Injury Induce Endotheliopathy Through Different Pathways.

Introduction: The contribution of endothelial injury to the pathogenesis of burn shock is not well characterized. This work investigates potential mechanisms underlying dysregulation of endothelial barrier function by burn patient plasmas.

Methods: Plasma was collected from burn-injured patients (n = 8) within 4 h of admission.

Longitudinal assessment of coagulation potential before, during, and following an in vitro fertilization cycle.

Introduction: The association between estrogen and hypercoagulability is well-established but little is known about coagulation dynamics during IVF. Our goal was to measure coagulation potential prior to, during, and following an IVF cycle and to investigate differences by conception outcome.

Materials And Methods: Patients undergoing IVF with fresh embryo transfer at a single academic center using oral contraceptive pills for cycle batching underwent evaluation of thrombin generation using the calibrated automated thrombogram at multiple points during the IVF cycle.

Placental Maternal Vascular Malperfusion is Associated with Prepregnancy and Early Pregnancy Maternal Cardiovascular and Thrombotic Profiles.

Characteristics of maternal vascular malperfusion (MVM) are frequently observed in placentas from pregnancies impacted by preeclampsia, intrauterine growth restriction, preterm labor, and intrauterine fetal demise. We sought to evaluate the associations of features of MVM with subclinical measures of cardiovascular health and coagulation potential in healthy young women. Sixty-three healthy young women were recruited and assessed prior to pregnancy on cycle day 9 ± 4, at gestational age 90 ± 6 of early pregnancy, and gestational age 216 ± 5 of late pregnancy.

A natural history study of coagulopathy in a porcine 40% total body surface area burn model reveals the time-dependent significance of functional assays.

Various studies have reported discordant results on the magnitude and direction of burn-induced coagulopathy (BIC), which has recently been associated with multiple organ dysfunction syndrome (MODS) and death. The increased mechanistic understanding of BIC is due, in part, to novel assays that have expanded the armamentarium beyond traditional tests like PT and aPTT. Still, BIC is a dynamic process, and the progression is difficult to define in the thermally-injured.
