Abstract
BACKGROUND Spontaneous intracerebral hemorrhage (sICH) is a major health concern and has high mortality rates up to 52%. Despite a decrease in its incidence, fatality rates remain unchanged; understanding and preventing of factors associated with mortality and treatments for these are needed. Blood pressure variability (BPV) has been shown to be a potential modifiable factor associated with clinical outcomes in patients with traumatic intracerebral hemorrhage and sICH. Few data are available on the effect of intracranial pressure (ICP) variability (ICPV) and outcomes in patients with sICH. The goal of our study was to investigate the association between ICPV and BPV during the first 24 h of intensive care unit (ICU) admission and external ventricular drain (EVD) placement, and mortality in patients with sICH who were monitored with an EVD. METHODS We conducted a single-center retrospective study of adult patients admitted to an ICU with a diagnosis of sICH who required EVD placement during hospitalization. We excluded patients with ICH secondary to other pathological conditions such as trauma, underlying malignancy, or arteriovenous malformation. Blood pressure and ICP measurements were collected and recorded hourly during the first 24 h of ICU admission and EVD placement, respectively. Measures of variability used were standard deviation (SD) and successive variation (SV). Primary outcome of interest was in-hospital mortality, and secondary outcomes were hematoma expansion and discharge home (a surrogate for good functional outcome at discharge). Descriptive statistics and multivariable logistic regressions were performed. RESULTS We identified 179 patients with sICH who required EVD placement. Of these, 52 (29%) patients died, 121 (68%) patients had hematoma expansion, and 12 (7%) patients were discharged home. Patient's mean age (± SD) was 56 (± 14), and 87 (49%) were women. The mean opening ICP (± SD) was 21 (± 8) and median ICH score (interquartile range) was 2 (2-3). Multivariable logistic regression found an association between ICP-SV and ICP-SD and hematoma expansion (odds ratio 1.6 [1.03-2.30], p = 0.035 and odds ratio 0.77 [0.63-0.93] p = 0.009, respectively). CONCLUSIONS Our study found an association between ICPV and hematoma expansion in patients with sICH monitored with an EVD. Measures of ICPV relating to rapid changes in ICP (ICP-SV) were associated with a higher odds of hematoma expansion, whereas measures relating to tight control of ICP (ICP-SD) were associated with a lower odds of hematoma expansion. One measure of BPV, sytolic blood pressure maximum-minimum (SBP max-min), was found to be weakly associated with discharge home (a surrogate for good functional outcome at hospital discharge). More research is needed to support these findings.

Abstract
Blood pressure variability, the variation of blood pressure during a certain period, results from the interaction of hemodynamic, neuronal, humoral, behavioral, and environmental factors. Cerebral autoregulation is impaired in acute cerebrovascular disease. In these patients, increased blood pressure variability may provoke or exacerbate secondary brain injury. In fact, available data showed that increased Blood pressure variability is associated with worse outcomes after acute ischemic stroke, intracerebral hemorrhage, and aneurysmal subarachnoid hemorrhage. Consequently, blood pressure variability may represent a usual modifiable therapeutic target. This concept this particularly attractive because reduction of blood pressure variability can be feasible in regions with lower resources and can be applicable to patients with various forms of acute stroke. Prospective studies are needed to further clarify the relationship between blood pressure variability and secondary brain damage, and the determinants of blood pressure variability in different clinical populations. Ultimately, cerebrovascular disease-specific randomized controlled trials aimed at reducing blood pressure variability, irrespective of the absolute blood pressure values, are needed to determine if reduction of blood pressure variability can improve outcomes in patients with acute cerebrovascular disease.

Abstract
INTRODUCTION Blood pressure variability (BPV) has been shown to correlate with intraparenchymal hematoma progression (HP) and worse outcomes in patients with spontaneous intracerebral hemorrhage (sICH). However, this association has not been elucidated in patients with traumatic intraparenchymal hemorrhage or contusion (tIPH). We hypothesized that 24 h-BPV from time of admission is associated with hemorrhagic progression of contusion or intraparenchymal hemorrhage (HPC), and worse outcomes in patients with tIPH. METHOD We performed a retrospective observational analysis of adult patients treated at an academic regional Level 1 trauma center between 01/2018-12/2019. We included patients who had tIPH and ≥ 2 computer tomography (CT) scans within 24 h of admission. HP, defined as ≥30% of admission hematoma volume, was calculated by the ABC/2 method. We performed stepwise multivariable logistic regressions for the association between clinical factors and outcomes. RESULTS We analyzed 354 patients' charts. Mean age (Standard Deviation [SD]) was 56 (SD = 21) years, 260 (73%) were male. Mean admission hematoma volume was 7 (SD =19) cubic centimeters (cm3), 160 (45%) had HP. Coefficient of variation in systolic blood pressure (SBPCV) (OR 1.03, 95%CI 1.02-1.3, p = 0.026) was significantly associated with HPC among patients requiring external ventricular drain (EVD). Difference between highest and lowest systolic blood pressure (SBPmax-min) (OR 1.02, 95%CI 1.004-1.03, p = 0.007) was associated with hospital mortality. CONCLUSION SBPCV was significantly associated with HP among patients who required EVD. Additionally, increased SBPmax-min was associated with an increase in mortality. Clinicians should be cautious with patients' blood pressure until further studies confirm these observations.

Abstract
PURPOSE OF REVIEW Nontraumatic intracerebral hemorrhage (ICH) is the second most common type of stroke. This article summarizes the basic pathophysiology, classification, and management of ICH and discusses the available evidence on therapy for hematoma, hematoma expansion, and perihematomal edema. RECENT FINDINGS Current available data on potential therapeutic options for ICH are promising, although none of the trials have shown improvement in mortality rate. The literature available on reversal of anticoagulation and antiplatelet agents after an ICH and resumption of these medications is also increasing. SUMMARY ICH continues to have high morbidity and mortality. Advances in therapeutic options to target secondary brain injury from the hematoma, hematoma expansion, and perihematomal edema are increasing. Data on reversal therapy for anticoagulant-associated or antiplatelet-associated ICH and resumption of these medications are evolving.

Abstract
INTRODUCTION Intracerebral haemorrhage (ICH) is associated with high morbidity and mortality. Blood pressure (BP) control is one of the main management strategies in acute ICH. Limited data currently exist regarding intracranial pressure (ICP) in acute ICH. The relationship between BP lowering and ICP is yet to be fully elucidated. METHODS We conducted a systematic review to investigate the effects of BP lowering on ICP in acute ICH. The study protocol was registered on PROSPERO (CRD42019134470). RESULTS Following PRISMA guidelines, MEDLINE, EMBASE and CENTRAL were searched for studies on ICH with BP and ICP or surrogate measures. 1096 articles were identified after duplicates were removed; 18 studies meeting the inclusion criteria. Dihydropyridine calcium channel blockers (CCBs) were the most common agent used to lower BP, but had a varying effect on ICP. Other BP-lowering agents used also had a varying effect on ICP. DISCUSSION AND CONCLUSION Further work, including large observational or randomized interventional studies, is needed to develop a better understanding of the effect of BP lowering on ICP in acute ICH, which will assist the development of more effective management strategies. TRIAL REGISTRATION The study protocol was registered on PROSPERO (CRD42019134470) on 29/05/2019.

Abstract
Background Spontaneous intracranial hemorrhage (sICH) is associated with high mortality. Little information exists to guide initial resuscitation in the emergency department (ED) setting. However, blood pressure variability (BPV) and mechanical ventilation (MV) are known risk factors for poor outcome in sICH. Objectives The objective was to examine the associations between BPV and MV in ED (EDMV) and between two ED interventions - post-MV sedation and hyperosmolar therapy for elevated intracranial pressure - and BPV in the ED and in-hospital mortality. Methods We retrospectively studied adults with sICH and external ventricular drainage who were transferred to a quaternary academic medical center from other hospitals between January 2011 and September 2015. We used multivariable linear and logistic regressions to measure associations between clinical factors, BPV, and outcomes. Results We analyzed ED records from 259 patients. There were 143 (55%) EDMV patients who had more severe clinical factors and significantly higher values of all BPV indices than NoEDMV patients. Two clinical factors and none of the severity scores (i.e., Hunt and Hess, World Federation of Neurological Surgeons Grades, ICH score) correlated with BPV. Hyperosmolarity therapy without fluid resuscitation positively correlated with all BPV indices, whereas propofol infusion plus a narcotic negatively correlated with one of them. Two BPV indices, i.e., successive variation of blood pressure (BPSV) and absolute difference in blood pressure between ED triage and departure (BPDepart - Triage), were significantly associated with increased mortality rate. Conclusion Patients receiving MV had significantly higher BPV, perhaps related to disease severity. Good ED sedation, hyperosmolar therapy, and fluid resuscitation were associated with less BPV and lower likelihood of death.

Abstract
OBJECTIVE Patients with spontaneous intracranial hemorrhage (sICH) have poor outcomes, in part because of blood pressure variability (BPV). Patients with sICH causing elevated intracranial pressure (ICP) are frequently transferred to tertiary centers for neurosurgical interventions. We hypothesized that BPV and care intensity during transport would correlate with outcomes in patients with sICH and elevated ICP. METHODS We analyzed charts from adult sICH patients who were transferred from emergency departments to a quaternary academic center from January 1, 2011, to September 30, 2015, and received external ventricular drainage. Outcomes were in-hospital mortality and the Glasgow Coma Scale on day 5 (HD5GCS). Multivariable and ordinal logistic regressions were used for associations between clinical factors and outcomes. RESULTS We analyzed 154 patients, 103 (67%) had subarachnoid hemorrhage and 51 (33%) intraparenchymal hemorrhage; 38 (25%) died. BPV components were similar between survivors and nonsurvivors and not associated with mortality. Each additional intervention during transport was associated with a 5-fold increase in likelihood to achieve a higher HD5GCS (odds ratio = 5.4; 95% confidence interval, 1.7-16; P = .004). CONCLUSION BPV during transport was not associated with mortality. However, high standard deviation in systolic blood pressure during transport was associated with lower HD5GCS in patients with intraparenchymal hemorrhage. Further studies are needed to confirm our observations.
