Abstract
Objective:
Systemic inflammatory response syndrome (SIRS) and hematoma expansion are both associated with worse outcomes after intracerebral hemorrhage (ICH), but their relationship remains unclear. We sought to determine the association between SIRS and hematoma expansion after ICH.
Methods:
We performed a retrospective cohort study of patients admitted to our hospital from 2013 to 2020 with primary spontaneous ICH with at least two head CTs within the first 24 hours. Patients were excluded if they had a decompressive craniectomy, intracranial vascular lesions or malignancy, or coagulopathy. Hematoma volume was measured using the ABC/2 method; hematoma expansion was defined as 6mL or 33% growth between the first and second scan. We compared patients with and without SIRS using Pearson’s χ2, students T and Wilcoxon rank sum tests. The relationship between admission SIRS and hematoma expansion was assessed using univariate and multivariate regression analysis.
Results:
Of 187 patients with ICH, 73 (39%; mean age 6617, 40% female) met inclusion criteria. Of those, 38 (52%) had SIRS on admission. Admission systolic blood pressure (SBP) was significantly higher in patients with SIRS compared to those without (169 [IQR 133- 205] vs 152 [125- 179] mm Hg, p= 0.02). There was no difference in mean days to first antibiotic administration (6.3 vs 5.6, p=0.78), admission platelets (227 vs 243, p= 0.38) or initial hematoma volume (23 vs 15, p=0.16). Hematoma expansion occurred in 14 patients, 11 (79%) of whom also had SIRS. A significantly greater percentage of patients with SIRS had mRS 4-6 at discharge (87 vs 67%, p=0.05). SIRS was significantly associated with hematoma expansion (OR 4.35, 95% CI 1.10-17.20, p= 0.04) on univariate analysis. The association remained statistically significant after adjusting for admission SBP, platelets, and initial hematoma volume (OR 4.54, 95% CI 1.01-20.60, p= 0.05).
Conclusion:
Presence of SIRS on admission is associated with hematoma expansion within the first 24 hours. Further research is needed to better understand this association, which may enable us to identify early on and treat those patients at highest risk for decompensation.

Abstract
Introduction:
While the thrombotic complications of COVID-19 have been described, there are limited data on its implications in hemorrhagic stroke. The clinical characteristics, underlying stroke mechanism, and outcomes in this group of patients are especially salient as empiric therapeutic anticoagulation becomes increasingly common in the treatment and prevention of thrombotic complications of COVID-19.
Methods:
We conducted a retrospective cohort study of patients with hemorrhagic stroke (both non-traumatic intracerebral hemorrhage and spontaneous non-aneurysmal subarachnoid hemorrhage) who were hospitalized between 3/1/20-5/15/20 at a NYC hospital system, during the coronavirus pandemic. We compared the demographic and clinical characteristics of patients with hemorrhagic stroke and COVID-19 to those without COVID-19 admitted to our hospital between 3/1/20-5/15/20 (contemporary controls) and 3/1/19-5/15/19 (historical controls), using Fischer’s exact test and non-parametric testing. We adjusted for multiple comparisons using the Bonferroni method.
Results:
During the study period, 19 out of 4071 (0.5%) patients who were hospitalized with COVID-19 had hemorrhagic stroke on imaging. Of all COVID-19 with hemorrhagic stroke, only 3 had non-aneurysmal SAH without intraparenchymal hemorrhage. Among hemorrhagic stroke and COVID-19 patients, coagulopathy was the most common etiology (73.7%); empiric anticoagulation was started in 89.5% vs 4.2% of contemporary and 10.0% of historical controls (both with p =<0.001). Compared to contemporary and historical controls, COVID-19 patients had higher initial NIHSS scores, INR, PTT and fibrinogen levels. These patients also had higher rates of in-hospital mortality [84.6% vs. 4.6%, p =<0.001]. Sensitivity analyses excluding patients with strictly subarachnoid hemorrhage yielded similar results.
Conclusion:
We observed an overall low rate of imaging-confirmed hemorrhagic stroke among patients hospitalized with COVID-19. Most hemorrhages in COVID-19 patients occurred in the setting of therapeutic anticoagulation and were associated with increased mortality. Further studies are needed to evaluate the safety and efficacy of therapeutic anticoagulation in COVID-19 patients.

Abstract
Introduction:
The association between race and white matter hyperintensities (WMH) and cerebral microbleeds in patients with intracerebral hemorrhage (ICH) is controversial. We examined the relationship between race and social determinants of health with WMH and microbleeds in ICH.
Methods:
We performed a retrospective study of patients at a tertiary care hospital between 2013 and 2020 who presented with ICH and underwent MRI of the brain. MRIs were evaluated for the presence of microbleeds and WMH severity (defined by the Fazekas scale; severe WMH defined as Fazekas 3). We assessed for an association of sex, race, ethnicity, employment status, median household income by zip code, education level, and insurance status with the severity of WMH or presence of microbleeds.
Results:
We identified 105 patients (median age 65.5 (IQR 53-76); 51% females; 13.2% Black) with ICH who had an MRI of the brain. Median ICH score was 1 [IQR 0-2] and median hematoma size was 15.9 ml (SD 19.7). High school graduation was the highest education level in 13.2%, and 57.5% had private insurance. Median income by zip code was $87,667 (IQR $65,900-$117,923). Severe WMH was observed in 19.8% and 52.8% of patients had microbleeds. There was no significant difference in sex, insurance status or median income for patients with or without severe WMH nor those with or without microbleeds. Severe WMH was more common among older patients (p=0.001), Black patients (p=0.03), patients with hypertension (p=0.03), and those with lower levels of education (p=0.03). In multivariable analyses, Black race was associated with severe WMH when adjusting for age and history of hypertension (OR 6.13 95% CI 1.14-25.98, p=0.01) but the effect size attenuated and the association disappears when adding education level to the model (OR 3.38 95% CI 0.48-23.76, p = 0.2). Age and history of hypertension were associated with presence of microbleeds (p<0.01 for both), but there was no association between presence of microbleeds and Black race or education level.
Conclusion:
Although Black race was associated with severe WMH, this association did not remain after adjusting for level of education. Our findings suggest that social determinants of health can modify the association between race and imaging biomarkers of ICH.

Abstract
BACKGROUND AND IMPORTANCE Spinal cord infarction is rare but can be extremely disabling. Prompt diagnosis and treatment of these infarcts is important for patient outcomes. While intravenous thrombolytic therapy is a well-established form of treatment in circumstances of cerebral stroke, it has only recently been successfully used in a few incidents of spinal cord ischemia. We present a case of anterior spinal artery (ASA) territory ischemia treated with ASA intra-arterial thrombolytic therapy. CLINICAL PRESENTATION A 52-year-old male presented with acute onset of severe lumbar pain, rapidly progressing paraplegia and loss of pain and temperature sensation, with preservation of proprioception and vibratory sensation at the L1 level and below on the right and at the L3 level and below on the left. MRI showed restricted diffusion involving the cord at and below L1 level, with normal cord T2 signal. Digital subtraction spinal angiography showed ASA cutoff in the descending limb at the level of L1. Intra-arterial tissue plasminogen activator (t-PA) combined with verapamil and eptifibatide was administered within the ASA and the patient had significant neurological improvement immediately postoperatively and at 8-month clinical follow-up. CONCLUSION Direct ASA intra-arterial thrombolysis is feasible, and this drug combination might be an effective therapy for spinal stroke.

Abstract
INTRODUCTION The coronavirus disease 2019 (Covid-19) pandemic has led to challenges in provision of care, clinical assessment and communication with families. The unique considerations associated with evaluation of catastrophic brain injury and death by neurologic criteria in patients with Covid-19 infection have not been examined. METHODS We describe the evaluation of six patients hospitalized at a health network in New York City in April 2020 who had Covid-19, were comatose and had absent brainstem reflexes. RESULTS Four males and two females with a median age of 58.5 (IQR 47-68) were evaluated for catastrophic brain injury due to stroke and/or global anoxic injury at a median of 14 days (IQR 13-18) after admission for acute respiratory failure due to Covid-19. All patients had hypotension requiring vasopressors and had been treated with sedative/narcotic drips for ventilator dyssynchrony. Among these patients, 5 had received paralytics. Apnea testing was performed for 1 patient due to the decision to withdraw treatment (n = 2), concern for inability to tolerate testing (n = 2) and observation of spontaneous respirations (n = 1). The apnea test was aborted due to hypoxia and hypotension. After ancillary testing, death was declared in three patients based on neurologic criteria and in three patients based on cardiopulmonary criteria (after withdrawal of support (n = 2) or cardiopulmonary arrest (n = 1)). A family member was able to visit 5/6 patients prior to cardiopulmonary arrest/discontinuation of organ support. CONCLUSION It is feasible to evaluate patients with catastrophic brain injury and declare brain death despite the Covid-19 pandemic, but this requires unique considerations.

Abstract
Background We explored factors associated with admission and discharge code status after nontraumatic intracranial hemorrhage. Methods We extracted data from patients admitted to our institution between January 1, 2013, and March 1, 2016 with nontraumatic intracerebral hemorrhage or subarachnoid hemorrhage who had a discharge modified Rankin Scale (mRS) of 4 to 6. We reviewed data based on admission and discharge code status. Results Of 88 patients who met inclusion criteria, 6 (7%) were do not resuscitate (DNR) on admission (aDNR). Do not resuscitate on admission patients were significantly older than those who were full code on admission (P = 0.04). There was no significant difference between admission code status and sex, marital status, active cancer, premorbid mRS, admission Glasgow Coma scale (GCS), Acute Physiology and Chronic Health Evaluation II (APACHE II) score, or bleed severity. At discharge, 66 (75%) patients were full code (dFULL), 11 (13%) were DNR (dDNR), and 11 (13%) were comfort care. African American and Hispanic patients were significantly more likely to be dFULL than Asian or white patients (P = .01) and less likely to be seen by palliative care (P = .004). Patients with less aggressive code status had higher median APACHE II scores (P = .008) and were more likely to have active cancer (P = .06). There was no significant difference between discharge code status and sex, age, marital status, premorbid mRS, discharge GCS, or bleed severity. Conclusions Limitation of code status after nontraumatic intracranial hemorrhage appears to be associated with older age, white race, worse APACHE II score, and active cancer. The role of palliative care after intracranial hemorrhage and the racial disparity in limitation and de-escalation of treatment deserves further exploration.

Abstract
BACKGROUND AND PURPOSE Acute rehabilitation is known to enhance stroke recovery. However, poststroke lethargy and fatigue can hinder participation in rehabilitation therapies. We hypothesized that in patients with moderate to severe stroke complicated by poststroke fatigue and lethargy early stimulant therapy with modafinil increases favorable discharge disposition defined as transfer to acute inpatient rehabilitation or home. METHODS We retrospectively reviewed a cohort of patients with acute stroke admitted to the stroke service over a 3-year period. All patients 18 years or older with confirmed ischemic or hemorrhagic stroke, an NIHSS greater than or equal to 5 and documentation of fatigue/lethargy in clinical documentation were included. We compared patients that were treated with modafinil 50-200 mg to those managed with standard care. The primary outcome measure was discharge disposition. Secondary outcome was 90 day modified Rankin score (mRS). Statistical significance was determined using chi-square test for association and logistic regression models. Logistic regression models were derived in 2 ways with both raw data and an adjusted model that accounted for age, sex, and NIHSS score to account for the lack of randomization. RESULTS This study included 199 stroke patients (145 ischemic, 54 hemorrhagic). Seventy-two (36.2%) were treated with modafinil and 129 (64.8%) were discharged to acute inpatient rehabilitation, while none were recommended for discharge home. Median NIHSS for modafinil patients was 13.5 versus 11 for standard care patients (P = .059). In adjusted models, modafinil was associated with higher odds of favorable discharge disposition (OR 2.00, 95% CI 1.01-3.95). Favorable outcome at 90 days defined as mRS less than or equal to 2 occurred more frequently with modafinil (5.6% versus 3.3%) but this did not achieve statistical significance (P > .1). These results occurred despite the modafinil group requiring longer ICU stays and having more in-hospital complications such as infections and need for percutaneous gastrostomy tubes. The benefit of modafinil was seen across all subgroups except those with severe stroke (NIHSS ≥ 15). There were no significant adverse events associated with modafinil administration. CONCLUSIONS Modafinil use in acute in-hospital stroke patients with moderate stroke complicated by lethargy and fatigue was associated with improved discharge disposition. Randomized controlled trials are needed to further study the safety, efficacy, and long-term effects of modafinil in this patient population.

Abstract
Background:
Acute rehabilitation is known to enhance stroke recovery. However, post-stroke lethargy and fatigue can hinder participation in rehabilitation therapies. We hypothesized that in patients with moderate to severe stroke, early stimulant therapy with modafinil increases favorable discharge disposition defined as transfer to acute rehabilitation.
Methods:
We retrospectively reviewed a cohort of patients with acute stroke admitted over a 3 year period. Patients were excluded for low NIH Stroke Scale score (below 5) or absence of confirmed stroke on brain imaging. We compared patients that were treated with modafinil 50-200mg to those managed with standard care. The primary outcome measure was discharge disposition. Secondary outcome was modified Rankin Score after discharge. Statistical significance was determined using chi-square test for association and logistic regression models.
Results:
The study cohort included 199 patients (145 ischemic, 54 hemorrhagic). 72 (36.2%) were treated with modafinil and 129 (64.8%) were discharged to acute rehab. Median NIHSS for modafinil patients vs standard care patients was higher but did not reach statistical significance (median (IQR): 13.5 (15) vs 11 (10), p=0.059). In adjusted models, modafinil was associated with higher odds of favorable discharge disposition (OR 2.00, 95% CI 1.01-3.95). Favorable outcome at 90 days (mRS ≤ 2) occurred more frequently with modafinil (5.6% vs. 3.3%) but this did not achieve statistical significance (p>0.1). The benefit of modafinil was seen across all subgroups of patients, except those with severe stroke (NIHSS
>
15). There were no significant complications clearly linked to modafinil administration.
Conclusions:
Modafinil use in acute stroke patients with moderate to severe stroke was associated with improved discharge disposition. Randomized controlled trials are needed to further study the safety, efficacy, and long-term effects of modafinil in this population.

Abstract
BACKGROUND AND PURPOSE Infections are common after intracerebral hemorrhage, but little is known about the risk of serious infection requiring readmission after hospital discharge. METHODS To determine if infections are prevalent in patients readmitted within 30 days of discharge, we performed a retrospective cohort study of patients discharged from nonfederal acute care hospitals in California with a primary diagnosis of intracerebral hemorrhage between 2006 and 2010. We excluded patients who died during the index admission, were discharged against medical advice, or were not California residents. Our main outcome was 30-day unplanned readmission with primary infection-related International Classification of Diseases, Ninth Revision, Clinical Modification code. RESULTS There were 24 540 index intracerebral hemorrhage visits from 2006 to 2010. Unplanned readmissions occurred in 14.5% (n=3550) of index patients. Of 3550 readmissions, 777 (22%) had an infection-related primary diagnosis code. When evaluating primary and all secondary diagnosis codes, infection was associated with 1826 (51%) of readmissions. Other common diagnoses associated with readmission included stroke-related codes (n=840, 23.7%) and aspiration pneumonitis (n=154, 4.3%). The most common infection-related primary diagnosis codes were septicemia (n=420, 11.8%), pneumonia (n=124, 3.5%), urinary tract infection (n=141, 4.0%), and gastrointestinal infection (n=42, 1.2%). Patients with a primary infection-related International Classification of Diseases, Ninth Revision, Clinical Modification code on readmission had higher in-hospital mortality compared with other types of readmission (15.6% versus 8.0%, P<0.001). After controlling for other predictors of mortality, primary infection-related readmissions remained associated with in-hospital mortality (relative risk, 1.7; 95% confidence interval, 1.3-2.2). CONCLUSIONS Infections are associated with a majority of 30-day readmissions after intracerebral hemorrhage and increased mortality. Efforts should be made to reduce infection-related complications after hospital discharge.

Abstract
INTRODUCTION Comparison of rates of ventriculostomy-related infections (VRIs) across institutions is difficult due to the lack of a standard definition. We sought to review published definitions of VRI and apply them to a test cohort to determine the degree of variability in VRI diagnosis. MATERIALS AND METHODS We conducted a PubMed search for definitions of VRI using the search strings "ventriculostomy-related infection" and "ventriculostomy-associated infection." We applied these definitions to a test cohort of 18 positive cerebrospinal fluid (CSF) cultures taken from ventriculostomies at two institutions to compare the frequency of infection using each definition. RESULTS We found 16 unique definitions of VRI. When the definitions were applied to the test cohort, the frequency of infection ranged from 22 to 94% (median 61% with interquartile range (IQR) 56-74%). The concordance between VRI diagnosis and treatment with VRI-directed antibiotics for at least seven days ranged from 56 to 89% (median: 72%, IQR: 71-78%). CONCLUSIONS The myriad of definitions in the literature produce widely different frequencies of infection. In order to compare rates of VRI between institutions for the purposes of qualitative metrics and research, a consistent definition of VRI is needed.

Abstract
Recent clinical studies have suggested that treatment with atypical antipsychotic drugs, such as olanzapine, may slow progressive changes in brain structure in patients with schizophrenia. To investigate the possible neural basis of this effect, we sought to determine whether treatment with olanzapine would inhibit the loss of hippocampal neurons associated with the administration of the excitotoxin, kainic acid, in neonatal rats. At post-natal day 7 (P7), rats were exposed to kainic acid via intracerebroventricular administration. Neuronal loss within the CA2 and CA3 subfields of the hippocampus and neurogenesis within the dentate gyrus of the hippocampus were then assessed at P14 by Fluoro-Jade B and BrdU labeling, respectively. Daily doses of olanzapine (2, 6, or 12 mg/day), haloperidol (1.2 mg/kg), melatonin (10 mg/kg), or saline were administered between P7 and P14. Melatonin is an anti-oxidant drug and was included in this study as a positive control, since it has been observed to have neuroprotective effects in a variety of animal models. The highest dose of olanzapine and melatonin, but not haloperidol, ameliorated the hippocampal neuronal loss triggered by kainic acid administration. However, drug administration did not have a significant effect on the rate of neurogenesis. These results suggest that olanzapine has neuroprotective effects in a rat model of neurodevelopmental insult, and may be relevant to the observed effects of atypical antipsychotic drugs on brain structure in patients with schizophrenia.
