The Impact of Hyperthermia and Infection on Acute Ischemic Stroke Patients in the Intensive Care Unit

Abstract As ischemic stroke care advances with more patients eligible for mechanical thrombectomy, so too does the role of the neurosurgeon in these patients. Neurosurgeons are an important member of the team from triage through the intensive care unit. This paper explores current research and insights on the contributions of neurosurgeons in care of acute ischemic stroke patients in the acute setting.

AbstractBackgroundClinically relevant potential drug-drug interactions are considered preventable adverse drug reactions.ObjectiveThe aim of this study was to ascertain the frequency of potential drug-drug interactions in acute ischemic stroke patients and to explore factors associated with occurrence of potentially contraindicated drug-drug interactions.MethodsThis observational retrospective cohort and nested case-control study was carried out among patients treated for acute ischemic stroke at the Neurological Intensive Care Unit in the Clinical Centre Kragujevac, Serbia. The potentially drug-drug interactions for each day of hospitalization were identifi ed using Micromedex® soft ware. Based on the existence or absence of potentially contraindicated drug-drug interactions, the participants were divided into a group of cases (n=111) and the control group (n=444).ResultsA total of 696 patients were analysed. All patients had a minimum of one potential drug-drug interaction during hospitalization. The most common drugs involved in potential drug-drug interactions were aspirin (8.02%), diclofenac (7.49%) and warfarin (7.14%). The number of medications prescribed for simultaneous use during hospitalisation and the use of antipsychotics in therapy signifi cantly increased the likelihood of potentially contraindicated drug-drug interactions aft er adjustment by means of logistic regression for 1.2 and 3 times, respectively.ConclusionsThis study suggests that patients with acute ischemic stroke are frequently exposed to potential drug-drug interactions. It is essential to identify potentially drug-drug interactions in these patients as early as possible in order to prevent adverse drug reactions and ensure safe recovery. Besides, full attention should be paid when adding each new medication in therapy, particularly when a neurologist decides to prescribe antipsychotics, such as risperidone.

Background/Objective: There is growing importance on discovering factors that delay time to intervention for acute ischemic stroke (AIS) patients, as rapid intervention remains essential for better patient outcomes. The management of these patients involves a multidisciplinary effort and quality improvement initiatives to safely increase treatment with intravenous thrombolytic (IV tPa). The objective of this pilot is to evaluate factors of acute stroke care in the emergency department (ED) and the impact they have on IV tPa administration. Methods: A sample of 89 acute ischemic stroke patients that received IV tPa from a single academic medical institution was selected for retrospective analysis. System characteristics (presence of a stroke nurse and time of day) and patient characteristics (mode of arrival and National Institutes of Health Stroke Scale score (NIHSS) on arrival) were analyzed using descriptive statistics and multiple regression to address the study question. Results: The mean door to needle time is 53.74 minutes ( + 38.06) with 74.2% of patients arriving to the ED via emergency medical services (EMS) and 25.8% having a stroke nurse present during IV tPa administration. Mode of arrival ( p = .001) and having a stroke nurse present ( p = .022) are significant predictors of door to needle time in the emergency department (ED). Conclusion: While many factors can influence door to needle times in the ED, we did not find NIHSS on arrival or time of day to be significant factors. Patients arriving to the ED by personal vehicle will have a significant delay in IV tPa administration, therefore emphasizing the importance of using EMS. Perhaps more importantly, collaborative efforts including the addition of a specialized stroke nurse significantly decreased time to IV tPa administration for AIS patients. With this dedicated role, accelerated triage and more effective management of AIS patients is accomplished, leading to decreased intervention times and potentially improving patient outcomes.

The Impact

Introduction : In acute ischemic stroke patients, current guidelines recommend noninvasive vascular imaging to identify intracranial vessel occlusions (VO) that may benefit from endovascular treatment (EVT). However, VO can be missed in CT angiography (CTA) readings. We aim to evaluate the impact of consistently including CT perfusion (CTP) in admission stroke imaging protocols on VO diagnosis and EVT rates. Methods : We included patients with a suspected acute ischemic stroke that underwent urgent non‐contrast CT, CTA and CTP from April to October 2020. Hypoperfusion areas defined by Tmax>6s delay (RAPID software), congruent with the clinical symptoms and a vascular territory, were considered due to a VO (CTP‐VO). Cases in which mechanical thrombectomy was performed were defined as therapeutically relevant VO (EVT‐VO). For patients that received EVT, site of VO according to digital subtraction angiography was recorded. Two experienced neuroradiologists blinded to CTP but not to clinical symptoms, retrospectively evaluated NCCT and CTA to identify intracranial VO (CTA‐VO). We analyzed CTA‐VO sensitivity and specificity at detecting CTP‐VO and EVT‐VO respecitvely. We performed a logistic regression to test the association of Tmax>6s volumes with CTA‐VO identification and indication of EVT. Results : Of the 338 patients included in the analysis, 157 (46.5%) presented a CTP‐VO, (median Tmax>6s: 73 [29‐127] ml). CTA‐VO was identified in 83 (24.5%) of the cases. Overall CTA‐VO sensitivity for the detection of CTP‐VO was 50.3% and specificity was 97.8%. Higher hypoperfusion volume was associated with an increased CTA‐VO detection, with an odds ratio of 1.03 (95% confidence interval 1.02‐1.04) (figure). DSA was indicated in 107 patients; in 4 of them no EVT was attempted due to recanalization or a too distal VO in the first angiographic run. EVT was performed in 103 patients (30.5%. Tmax>6s: 102 [63‐160] ml), representing 65.6% of all CTP‐VO. Overall CTA‐VO sensitivity for the detection of EVT‐VO was 69.9%. The CTA‐VO sensitivity for detecting patients with indication of EVT according to clinical guidelines was as follows: 91.7% for ICA occlusions and 84.4% for M1‐MCA occlusions. For all other occlusion sites that received EVT, the CTA‐VO sensitivity was 36.1%. The overall specificity was 95.3%. Among patients who received EVT, CTA‐VO was not detected in 31 cases, resulting in a false negative rate of 30.1%. False negative CTA‐VO cases had lower Tmax>6s volumes (69[46‐99.5] vs 126[84‐169.5]ml, p<0.001) and lower NIHSS (13[8.5‐16] vs 17[14‐21], p<0.001). Conclusions : Systematically including CTP perfusion in the acute stroke admission imaging protocols may increase the diagnosis of VO and rate of EVT.

The Impact

Introduction/Background information: At the onset of acute stroke symptoms, speed, capability, safety and skill are essential-lost minutes can be the difference between full recoveries, poor outcome, or even death. The Joint Commission's Certificate of Distinction for Comprehensive Stroke Centers recognizes centers that make exceptional efforts to foster better outcomes for stroke care. While many hospitals have been surveyed, Cedars Sinai was the 5 th hospital in the nation to receive this certification. Researchable question: Does Comprehensive stroke certification (CSC) demonstrate a significant effect on volume and quality of care? Methods: We assembled a cross-functional, multidisciplinary expert team representing all departments and skill sets involved in treating stroke patients. We carefully screened eligible patients with acute ischemic stroke We assessed the number of patients treated at Cedars-Sinai with IV-T-pa t 6 months before and then 6 months after CSC and the quality of their care including medical treatment and door to needle time. Results: In the 6 months prior to Joint Commissions Stroke Certification we treated 20 of 395acute stroke patients with t-PA with an average CT turnaround time of 31±19minutes and an average Door to needle time (DTNT) of 68±32minutes. In the 6 months since Joint Commission Stroke Certification we have increased the number of acute stroke patients treated by almost double. There were 37 out of 489(P=0.02, Chi Square) patients treated with IV t-PA with an average CT turnaround time of 22±7minutes (p=0.08, t-test, compared to pre-CSC) and an average DTNT of 61± 23minutes (not different than pre-CSC). Conclusion: We conclude that Joint Commission Certification for stroke was associated with an increased rate of treatment with IV rt-PA in acute ischemic stroke patients. We were not able to document an effect on quality of care. Further studies of the impact of CSC certification are warranted.

Abstract: Acute ischemic stroke (AIS) has been reported in patients with coronavirus disease 2019 (COVID-19). The cause of AIS in COVID-19 patients has not been fully understood, but COVID-19 is known to cause hypercoagulation characterized by increased d-dimer levels, and cytokine storms. Some AIS patients with COVID-19 require intensive care. This study was aimed to determine the description of AIS patients with COVID-19 admitted to the intensive care unit. This was a literature review study using three databases, as follows: Pubmed, ClinicalKey, and Science Direct. The keywords used were acute ischemic stroke AND COVID-19 AND intensive care unit. The results showed that after being selected based on inclusion and exclusion criteria, 10 literatures were obtained. There were 20 subjects and most were female (55%) and age group of 60-69 years old (35%). The most common cardiovascular risk factor was hypertension (80%, n=10). There were some increases in the levels of LDH, CRP, d-dimer, ferritinin, and fibrinogen. On radiological examination performed, there were cases with bilateral pulmonary infiltrate (33%) and ground-glass opacities (67%) (n = 6). In conclusion, the characteristics of AIS patients with COVID-19 admitted to the intensive care room were mostly female, age group 60-69 years, had cardiovascular risk factors for hypertension, had elevated levels of LDH, CRP, d-dimer, ferritinin, and fibrinogen, and had ground-glass opacity on radiological imaging.Keywords: acute ischemic stroke, COVID-19, intensive care unit Abstrak: Stroke iskemik akut telah dilaporkan pada pasien dengan coronavirus disease 2019 (COVID-19).

Age And Sex

Background Temporal trends in life‐sustaining care after acute stroke are not well characterized. We sought to determine contemporary trends by age and sex in the use of life‐sustaining care after acute ischemic stroke and intracerebral hemorrhage in a large, population‐based cohort. Methods and Results We used linked administrative data to identify all hospitalizations for acute ischemic stroke or intracerebral hemorrhage in the province of Ontario, Canada, from 2003 to 2017. We calculated yearly proportions of intensive care unit admission, mechanical ventilation, percutaneous feeding tube placement, craniotomy/craniectomy, and tracheostomy. We used logistic regression models to evaluate the association of age and sex with life‐sustaining care and determined whether trends persisted after adjustment for baseline factors and estimated stroke severity. There were 137 358 people with acute ischemic stroke or intracerebral hemorrhage hospitalized during the study period. Between 2003 and 2017, there was an increase in the proportion receiving care in the intensive care unit (12.4% to 17.7%) and mechanical ventilation (4.4% to 6.6%). There was a small increase in craniotomy/craniectomy, a decrease in percutaneous feeding tube use, and no change in tracheostomy. Trends were generally consistent across stroke types and persisted after adjustment for comorbid conditions, stroke‐center type, and estimated stroke severity. After adjustment, women and those aged ≥80 years had lower odds of all life‐sustaining care, although the disparities in intensive care unit admission narrowed over time. Conclusions Use of life‐sustaining care after acute stroke increased between 2003 and 2017. Women and those at older ages had lower odds of intensive care, although the differences narrowed over time. Further research is needed to determine the reasons for these findings.

The Impact

Background: Sphenopalatine ganglion (SPG) stimulation enhances collateral flow, stabilizes blood-brain barrier, and showed evidence of benefit in patients with confirmed cortical involvement (CCI) when started 8-24h after onset in the ImpACT-24B randomized trial. To characterize SPG stimulation benefit magnitude, we derived number needed to treat (NNT) values based on shifts over all levels of 3 month global disability. Methods: From the distribution of the 7-level modified Rankin Scale (mRS) at 3m in SPG- and sham-stimulation CCI patients, NNT to benefit (NNTB) and NNT to harm (NNTH) values were derived by automated (algorithmic min-max) and expert generation of joint outcome distribution tables. For dichotomized mRS outcomes, net NNT values were derived directly from absolute risk differences. Results: Among 520 patients with confirmed cortical infarction ineligible for thrombolysis, 244 were treated with SPG and 276 with sham stimulation. NNT values for dichotomized and shift mRS outcomes are shown in the Table. Of the 6 possible binary cutpoints on the mRS, 4 showed more favorable outcome with SPG stimulation. The dichotomized endpoint with the greatest group difference was ambulatory and capable of bodily self-care (mRS 0-3), 62.3% vs 51.1%, NNTB 8.9. Across all 6 individual possible dichotomizations of the mRS, the NNTB ranged from 8.9 to -166.7. For shifts by 1 or more levels across all 6 transitions of the mRS, the biologically most plausible NNTB was 5.7 (IQR 5.6-6.5), NNTH 34.5 (IQR 30.3-40.0), and net NNTB 6.8 (IQR 6.5-7.7), These values correlated closely with the automatically derived net NNTB of 5.9. Conclusions: The findings of this pivotal trial indicate that, out of every 1000 CCI patients treated with SPG stimulation, 146 patients will have a less disabled 3-month outcome, including 76 more who will be functionally independent. SPG stimulation can substantially improve the outcome of thrombolysis-ineligible acute ischemic stroke patients.

The Impact

Introduction: To date, few studies have assessed the influence of infection on neurological deterioration (ND) and other outcome measures in acute ischemic stroke. Methods: Patients admitted to our stroke center (07/08-12/10) were retrospectively assessed. Patients were excluded if they had an in-hospital stroke, unknown time of symptom onset, or delay from symptom onset to hospital arrival >48 hours. Positive blood or urine culture, or chest x-ray consistent with pneumonia were classified as infection and stratified according to whether the infection was diagnosed within the first 24 hours of admission or after 24 hours. ND was defined as an increase ≥2 points on the NIHSS score within a 24hr period. Poor functional outcome was defined as a mRS score of 3-6 on discharge. Results: Of the 334 patients included in this study, 78 had an infection (19 on admission). The majority of infections were found in the urinary tract (64%), while pneumonia (37%) and bacteremia (24%) were also common. Infection on admission was predictive of ND (Table 1; OR=2.79, 95% CI 1.18-6.64, p=0.0211) and poor functional outcome (OR=3.0, 95% CI 1.1-7.9, p=0.0182). Developing an infection during acute hospitalization was an even stronger predictor of ND (OR=11.9, 95% CI 5.8-24.5, p<0.0001) and poor functional outcome (OR=56.4, 95% CI 7.7-414, p<0.0001). After adjusting for age, NIHSS at baseline and glucose on admission, the development of an infection during acute hospitalization remained a significant predictor of ND (OR=8.9, 95% CI 4.2-18.6, p<0.0001) and poor functional outcome (OR=41.7, 95% CI 5.2-337.9, p=0.005) while an infection on admission was no longer predictive of ND (OR=1.5, 95%CI 0.59-3.99, p=0.3738) or poor functional outcome (OR=1.09, 95%CI 0.3-3.9, p=0.8984). Conclusion: Our data suggest that ischemic stroke patients who develop an infection during their acute hospitalization are at increased odds of experiencing ND and of being discharged with significant disability.
