Aneurysmal subarachnoid hemorrhage (aSAH) is associated with high socio-economic burden. Prothrombotic states of early brain injury (EBI) and delayed cerebral ischemia (DCI) after aSAH determine morbidity and mortality. To understand how activated platelets might contribute to such prothrombotic states, we studied trends in coated-platelets during EBI and DCI periods. ⋯ Differences between peak coated-platelet levels and baseline levels were larger, on average for those with DCI [18.1 ± 9.6 vs. 10.6 ± 8.0; p = 0.03], MOCA < 26 [17.0 ± 7.8 vs. 10.7 ± 7.4; p = 0.05] and mRS 3-6 [24.8 ± 10.5 vs. 11.9 ± 7.6; p = 0.01]. Coated-platelet trends after aSAH predict DCI and short-term clinical outcomes. The degree of rise in coated-platelets is also associated with adverse clinical outcomes.

Observational StudyPreoperative Thromboelastographic Profile of Patients with Congenital Heart Disease: Association of Hypercoagulability and Decreased Heparin Response.
To describe the demographic and thromboelastographic characteristics of patients with congenital heart disease presenting with decreased heparin response before cardiac surgery. ⋯ Decreased response to heparin before cardiac surgery in patients with congenital heart disease is associated with preoperative hypercoagulability identified using a viscoelastic test. Additional studies are needed to better understand the etiology of decreased heparin response and potential clinical strategies to improve anticoagulation management.

The prevalence and impact of hypercoagulability (hypo) in severely injured patients early after injury remains unclear. We hypothesize that the predominant phenotype of postinjury coagulopathy is hypercoagulability (hyper) and it is associated with increased mortality. ⋯ These data support the ongoing need for goal directed resuscitation in trauma patients, it appears the optimal resuscitation strategy should be targeted towards normalization of coagulation status as both early hyper and hypocoagulability are associated with increased mortality.

Review Meta AnalysisScreening for occult cancer in idiopathic venous thromboembolism - Systemic review and meta-analysis.
Idiopathic venous thromboembolism (VTE) may be associated with an occult malignancy. Early detection of cancer might be translated to a better prognosis for these patients. However, the efficacy of extensive screening for cancer in patients with idiopathic VTE is controversial. ⋯ Extensive screening for malignancy after idiopathic VTE does not affect mortality rates. Yet, it yields more cancer diagnoses shortly after the VTE event. Further research is needed to determine whether extensive screening might be proper for specific high risk populations.

Elevated red blood cell distribution width (RDW) has been associated with thrombotic disorders including myocardial infarction, venous thromboembolism, and ischemic stroke, independent of other inflammatory and coagulation biomarkers. The purpose of this study was to determine whether elevated RDW is associated with cerebral infarction and poor outcome after aneurysmal subarachnoid hemorrhage (aSAH). ⋯ RDW elevation is associated with cerebral infarction and poor outcome after aSAH. Further evaluation of this association is warranted as it may shed light on mechanistic relations between anemia, inflammation, and thrombosis after aSAH.
