Intracranial Hemorrhage in Patients with a Left Ventricular Assist Device

BACKGROUND: There is a dearth of literature regarding management and outcomes of patients with a left ventricular assist device (LVAD) for advanced heart failure who develop intracranial hemorrhage (ICH). We conducted a case series from 2 centers highlighting patient outcomes and prognostic factors to help clinicians better understand and care for these high-risk patients. METHODS: A case series from 2 large-volume institutions (defined as large by the Nationwide Inpatient Sample hospital size, i.e., \u3e500 beds both with Departments of Neurosurgery and Advanced Heart Failure-Cardiology) was conducted to clarify the prognosis of patients with an LVAD and ICH. We included patients who were being treated with an LVAD who developed ICH. Patient-specific demographics and data regarding heart failure and intracranial hemorrhage characteristics were collected and analyzed to determine which factors contributed to overall survival. RESULTS: We analyzed 59 unique ICHs in patients being treated with an LVAD for heart failure. Initial Glasgow Coma Scale score, presence of midline shift, and ICH size were factors found to be predictive of mortality. One institution had a sicker patient population including patients with ICH with lower Glasgow Coma Scale score, presence of midline shift, and greater hemorrhage size, which led to overall higher mortality compared with the second institution. CONCLUSIONS: Patients being treated with an LVAD who develop ICH have poor outcomes. Predictive factors for same-admission mortality are lower initial Glasgow Coma Scale score, presence of midline shift, and greater ICH volume

Advanced Scientific Computing Research Network Requirements Review: Final Report 2015

The Energy Sciences Network (ESnet) is the primary provider of network connectivity for the U.S. Department of Energy Office of Science (SC), the single largest supporter of basic research in the physical sciences in the United States. In support of the Office of Science programs, ESnet regularly updates and refreshes its understanding of the networking requirements of the instruments, facilities, scientists, and science programs that it serves. This focus has helped ESnet to be a highly successful enabler of scientific discovery for over 25 years. In April 2015, ESnet and the Office of Advanced Scientific Computing Research (ASCR), of the DOE Office of Science, organized a review to characterize the networking requirements of the programs funded by the ASCR program office. Several key findings resulted from the review - they are discussed in this report, along with the case studies presented at the review
