The Cardiac Physiology Underpinning Exsanguination Cardiac Arrest: Targets for Endovascular Resuscitation
Exsanguination leading to cardiac arrest is the terminal phase of uncontrolled hemorrhage. Resuscitative interventions have focused on preload and afterload support. Outcomes remain poor due to several factors but poor coronary perfusion undoubtedly plays a role. The aim of this study is to characterize the relationship between arterial pressure and flow during hemorrhage in an effort to better describe the terminal phases of exsanguination. Male swine weighing 60 kg to 80 kg underwent splenectomy and instrumentation followed by a logarithmic exsanguination until asystole. Changes in hemodynamic parameters over time w...

Bleeding Related Episodes, Thrombotic Events and Platelet Counts Among Immune Thrombocytopenia Patients Receiving Second Line Therapy
CONCLUSIONS: This retrospective real world evidence study compares mean platelet response and burden of both BREs and TEs in ITP patients treated with different second-line treatments. Although there were significant differences in mean platelet counts achieved with the second-line treatments, TEs were observed with similar incidence across all treatments. Patients who received splenectomy had the highest mean platelet counts and also the highest proportion of patients who experienced TEs, though differences in TEs did not reach statistical significance. Incidence proportion of patients with BREs was lower in patients trea...

Validation of Sickle Cell Disease Severity Score in a Cohort of Hemoglobin SC Disease Patients
Conclusion: Despite having been derived from a SCD population that was 26% HbSC, the study was unable to validate the SSS within the cohort of HbSC patients. This may reflect the differences in patient population and/or therapeutic intervention between this cohort and the CSSCD cohort used in the construction of the SSS calculator. While SSS was found to correlate with 3 discrete markers of disease morbidity (TRJV, CVA, creatinine clearance), it appears that a new scoring system is required to accurately predict clinical mortality and morbidity in contemporary cohorts of adult HbSC disease patients.DisclosuresNo relevant c...

Increased Risk of Hemorrhagic and Ischemic Strokes in Patients With Splenic Injury and Splenectomy: A Nationwide Cohort Study
This study revealed that splenic injury and splenectomy were significantly associated with an increased risk of hemorrhagic and ischemic strokes. The results of this study may alert physicians and patients to the complications of splenic injury and splenectomy.
