Comparative Study
A population-based analysis of ethnic differences in admission to the intensive care unit after stroke.
Mexican-Americans (MAs) have shown lower post-stroke mortality compared to non-hispanic whites (NHWs). Limited evidence suggests race/ethnic differences exist in intensive care unit (ICU) admissions following stroke. Our objective was to investigate the association of ethnicity with admission to the ICU following stroke. ⋯ No overall association between ethnicity and ICU admission was observed in this community. ICU utilization alone does not likely explain ethnic differences in survival following stroke between MAs and NHWs.

Intracerebral hemorrhage (ICH) is a highly fatal disease with few proven treatments. Data to guide clinician decisions for therapies, including antiepileptic drugs (AED), are limited. Published studies on AED treatment in ICH have provided conflicting results. We investigated the effect of AED treatment on 90-day mortality after ICH in a large prospectively ascertained cohort. ⋯ These results suggest that AED treatment in acute ICH is not associated with 90-day mortality or outcome and that any detected association could arise by confounding by indication, in which the most severely affected patients are those in whom AEDs are prescribed. They provide a cautionary example of the limitations of drawing conclusions about treatment effects from observational data.

Perioperative serum brain natriuretic peptide and cardiac troponin in elective intracranial surgery.
There are some intracranial insults which are associated with cardiac abnormalities. Studies of these abnormalities have never been carried out in elective intracranial neurosurgery for the removal of brain tumors. Our prospective study aims at quantifying serum cardiac troponin T (cTnT) and N-terminal pro-brain natriuretic peptide (NT-proBNP) before and after elective intracranial neurosurgery for tumor resection in patients with no history of cardiac abnormality. ⋯ An intracranial mass effect is associated with higher NT-proBNP serum levels in patients with a brain neoplasm. Following elective intracranial surgery for brain tumor resection NT-proBNP values increase.

Prolonged emergency department length of stay (EDLOS) has been associated with worse patient outcomes, longer inpatient stays, and failure to meet quality measures in several acute medical conditions, but these findings have not been consistently reproduced. We performed this study to explore the hypothesis that longer EDLOS would be associated with worse outcomes in a large cohort of patients presenting with spontaneous intracerebral hemorrhage (ICH). ⋯ We found no effect of EDLOS on neurologic outcome or resource utilization for patients presenting with spontaneous ICH.

Cardiac injury is common after subarachnoid hemorrhage (SAH) and is associated with adverse early outcomes, but long-term effects are unknown. The first aim of this study was to compare the long-term rates of death, stroke, and cardiac events in SAH survivors versus a matched population without SAH. The second aim was to quantify the effects of cardiac injury on the outcome rates. ⋯ SAH survivors have increased long-term mortality and stroke rates compared with a matched non-SAH population. SAH-induced cardiac injury is associated with an increased risk of death and heart failure hospitalization.
