Background and purpose: Prediction of swallowing function in dysphagic patients with acute stroke is indispensable for discussing percutaneous endoscopic gastrostomy (PEG) placement. We performed a retrospective study using database of a large number of acute ischemic stroke patients to clarify predictors for acquisition of oral intake in chronic phase. Methods: A total 4,972 consecutive acute stroke patients were admitted to our stroke center during 8.5 years; a questionnaire was sent to all the survivors after 3 months of onset. We investigated nutritional access after 3 months of onset in 588 patients who could not eat orally 10 days after admission, and analyzed predictive factors for their acquisition of oral intake. Continuous variables were dichotomized to identify the most sensitive predictors; the cutoff values were investigated by receiver operating characteristics curve analysis. Results: Out of 588 dysphagic patients, 75 died during the 3 months, and 143 (28%) of the residual 513 achieved oral intake after 3 months. In logistic-regression models, age ≤80 years, absence of hyperlipidemia, absence of atrial fibrillation, modified Rankin Scale score 0 before onset, and low National Institutes of Health Stroke Scale (NIHSS) score independently predicted oral intake 3 months after onset. From two different model analyses, NIHSS score ≤17 on day 10 (OR 3.63, 95% CI 2.37-5.56) was found to be a stronger predictor for oral intake than NIHSS score ≤17 on admission (OR 2.34, 95% CI 1.52-3.59). At 3 months, 17/143 (12%) patients with oral intake were living at home, while only 1/370 (0.3%) patients without oral intake were. Conclusion: A quarter of dysphagic patients with acute stroke obtained oral intake 3 months after onset. Clinicians should be cautious about PEG placement for stroke patients with severe dysphagia who were independent prior to the stroke, aged ≤80 years, and show NIHSS score ≤17 on day 10, because their swallowing dysfunction may improve in a few months.

Introduction: Dysphagia occurs in up to two thirds of stroke patients and can lead to serious complications such as aspiration pneumonia, which is also linked to increased morbidity and mortality. Evidence-based guidelines recommend a bedside dysphagia assessment before oral intake in stroke patients regardless of initial stroke severity. Several studies have described registered nurses’ competency in terms of knowledge and skills regarding dysphagia screening. We aimed to examine the rate of aspiration pneumonia compared to the rate of dysphagia screening. Methods: A retrospective analysis of prospectively collected data at a single tertiary stroke center was carried out between January 2017 and June 2020. Data comparison was completed utilizing ICD-10 diagnosis codes to identify aspiration pneumonia in ischemic and hemorrhagic stroke patients. The data was reviewed to compare the compliance of a completed dysphagia screen prior to any oral intake to rate of aspiration pneumonia. Chi square tests were used to assess proportion differences in completed dysphagia screen and proportion of aspiration pneumonia diagnosis in the ischemic and hemorrhagic stroke patients. Results: We identified 3320 patient that met inclusion criteria. 67% were ischemic strokes, 22% were intracerebral hemorrhages and 11% were subarachnoid hemorrhages. Compliance with dysphagia screening decreased from 94.2% (n=1555/1650) in 2017-2018 to 74.0% (n=1236/1670) in 2019-2020, OR=0.17 (95%CI 0.14 - 0.22), p < 0.0001. Aspiration pneumonias increased from 58 (3.5%) in 2017-2018 to 77 (4.6%) in 2019-2020, but this difference was not statistically significant, OR=0.75 (95%CI 0.53 - 1.07), p = 0.11. Conclusion: We noted that the decrease in compliance with completing a dysphagia screen in patients with acute stroke prior to any oral intake was associated with a higher trend of aspiration pneumonia.

Abstract Purpose Mechanical thrombectomy (MT) is the first-line treatment in acute stroke patients presenting with large vessel occlusion (LVO). The efficacy of intravenous thrombolysis (IVT) prior to MT is being contested. The objective of this study was to evaluate the efficacy of MT without IVT in patients with no contraindications to IVT presenting directly to a tertiary stroke center with acute anterior circulation LVO. Materials and Methods We collected the data of 106 acute stroke patients who underwent MT in a single high-volume stroke center. Patients with anterior circulation LVO eligible for IVT and directly admitted to our institution who subsequently underwent MT were included. We recorded baseline clinical, laboratory, procedural, and imaging variables and technical, imaging, and clinical outcomes. The effect of intravenous thrombolysis on 3-month clinical outcome (mRS) was analyzed with univariate tests and binary and ordinal logistic regression analysis. Results Fifty-eight out of the 106 patients received IVT + MT. These patients had 2.6-fold higher odds of poorer clinical outcome in mRS shift analysis (p = 0.01) compared to MT-only patients who had excellent 3-month clinical outcome (mRS 0–1) three times more often (p = 0.009). There were no significant differences between the groups in process times, mTICI, or number of hemorrhagic complications. A trend of less distal embolization and higher number of device passes was observed among the MT-only patients. Conclusions MT without prior IVT was associated with an improved overall three-month clinical outcome in acute anterior circulation LVO patients.

Anticoagulant use, such as heparin, is usually contraindicated in acute stroke patients. We present a study of patients, who were treated with intravenous heparin after a stroke that were also found to have an intraluminal thrombus. Prior studies imply that recanalization is achieved with heparin; however heparin should only prevent thrombus propagation. Therefore it is unclear whether and how IV heparin can achieve recanalization of intraluminal thrombi in acute stroke patients. A retrospective review of all acute stroke patients from a single stroke center who received a therapeutic IV heparin infusion from 5/2006 to 9/2011 were included in the study. We compared patients who had complete/partial recanalization and/or improved flow versus those that did not, with both these groups on a standard intravenous heparin infusion protocol. Demographic data was compared between the groups. Average partial thromboplastin time (PTT) during heparin infusion, time between computed tomography angiographies (CTAs), time from stroke onset to receiving IV heparin, and vessel occluded were also compared between groups. Forty-one patients (19 female, 22 male) were included in the study with a total of 55 vessels (either carotid, middle cerebral artery, anterior cerebral artery, posterior cerebral artery/posterior circulation) having intraluminal thrombi; 31 patients had 41 vessels with either partial or complete recanalization of effected vessels, while 10 patients had 14 vessels that did not have at least one vessel recanalize while on heparin. Using t-test we noted that the average PTT between the vessels that had partial/complete recanalization group (61.74) and non-recanalization group (66.30) was not statistical significantly different (P=0.37).The average time in days on heparin between vascular imaging studies (CTA/conventional angiogram) in the group of vessels with partial/complete recanalization (7.12 days) and the ones with no change (6.11 days) was not significantly different between the two groups (P=0.59). Patient’s vessels receiving heparin for &lt;24 hours <em>versus</em> those &gt;24 hours did not significantly differ either (P=0.17). This study compares patient characteristics associated with recanalization of intraluminal thrombi in acute stroke patients on heparin. Recanalization of intraluminal thrombi are not associated with average PTT or duration on heparin.

Objectives: Animal models have shown that the spleen contracts and contributes to post-ischemic inflammation that may exacerbate brain injury and impair recovery. Translation of these findings in patients is challenging because of a lack of normative spleen volume (SV) data. We created normograms of SV for an adult at-risk population, quantified splenic contraction (SC) in stroke patients, and characterized patients with SC. Methods: We enrolled 158 healthy volunteers (HV) with matching age and gender distribution with that of our stroke center registry. Spleen ultrasounds were performed on 5 consecutive days. We used quantile regression models to identify predictors of SV for HV. Gender and body surface area (BSA) were used to construct percentile based normograms of SV, and the expected pre-stroke SV were calculated, from which SC was quantified. We also enrolled a cohort of 170 patients with acute stroke and intracerebral hemorrhage within 24 hours of symptom onset and performed serial spleen ultrasound measurements during hospitalization. Logistic regression was used to determine factors associated with SC. Results: Normograms for SV in healthy males and females based on BSA were created (Figure 1). Over a 5-day consecutive period of daily spleen measurements, the maximum day to day variation was 10.6 cm3. Based on these findings, stroke patients with a normalized SV below 20 cm3 of their expected SV, were classified as having SC. Excluding stroke mimics, 158 patients were included in the analyses, of which 64 (40.5%) had SC detected within 24 hrs of symptom onset. African-American race, older age, and history of previous stroke were significantly associated with SC (Table 1). Conclusion: The spleen does appear to reduce in size after stroke in some specific subgroups of patients with acute stroke and brain hemorrhage. The biological relevance of SC to the inflammatory response and functional outcomes of stroke patients are currently being studied in our study cohorts.

Purpose: To standardize the care of acute stroke patients who receive IV tPA being transported by ground EMS from a treating hospital to a stroke center. Background: National consensus guidelines exist for the hospital management of patients receiving IV tPA for acute ischemic stroke. Such patients require close monitoring and management to minimize risk of clinical deterioration. Although patients are often emergently transported from local hospitals to a stroke center, there are no treatment specific national guidelines for managing such patients enroute. As a result, there is a need to develop and implement a standardized approach to guide EMS personnel, particularly in states like Georgia where the public health burden of stroke is high. Methods: In 2012, the “Georgia EMS Interfacility Ground Transport Protocol for Patients during/after IV tPA Administration for Acute Ischemic Stroke” was developed in conjunction with the Georgia Coverdell Acute Stroke Registry, the Georgia State Office of EMS, a representative group of Georgia hospitals and EMS providers. Stakeholders were brought together with the goal of creating a unified statewide protocol. The intent was to create a streamlined protocol which could be readily implemented by pre-hospital care providers. Results: Stakeholders discussed challenges and opportunities to change the process of pre-hospital care. Challenges included recognition of the broad diversity of EMS providers representing over 250 agencies in the state. Opportunities included establishing the framework for greater collaboration across organizations and providers. The final protocol was endorsed by both the Georgia Coverdell Acute Stroke Registry and the State Office of EMS, and distributed to all EMS regions in Georgia. EMS agencies are currently implementing the protocol. Conclusion: Engaging a diverse group of statewide stakeholders to develop a new treatment protocol enhances success in implementation and serves to further the public health mission of improving care of acute stroke patients.

Background and Purpose: Diffusion-weighted imaging-Alberta Stroke Programme Early CT Score (DWI-ASPECTS) has been associated with short-term and long-term neurological recovery and outcome in acute stroke patients treated with intravenous tissue plasminogen activator (IV-tPA). However, previous reports did not analyze the DW-ASPECTS based on the presence of major arterial occlusion. We investigated whether initial DWI-ASPECTS can predict the short-term neurological recovery in acute stroke patients with the middle cerebral artery occlusion (MCAO) treated with IV t-PA. Methods: Consecutive acute stroke patients with MCAO treated with IV t-PA within 3 hours of onset were enrolled from 2005 October to 2011 May. All patients were examined using DWI and magnetic resonance angiography on admission. Only patients with horizontal MCAO were included. Neurological deficits were assessed using National Institutes of Health Stroke Scale (NIHSS) score on admission and day 7. On day 7, dramatic recovery (DR) was defined as a ≥10 point reduction or a total NIHSS score of 0 or 1. Good recovery (GR) was a ≥4 point reduction, excluding DR. Worsening was a ≥4 point increase. Results: Seventy-one patients (median age [quartiles]; 77 [70-83], male; 44 [62%]) were enrolled into the study. The median NIHSS score was 18 (12-22). The median DWI-ASPECTS was 4 (6-9). Median DWI-ASPECTS was 7 (6-9) in 27 patients with DR group, 5 (4-9) in 13 with GR group, and 3 (2-6) in 17 with worsening (p<0.001). Median DWI-ASPECTS was 4 (3-6) in 4 (6%) patients with type2-parencymal hematoma within 7 days. Using ROC curve, the optimal cut-off DWI-ASPECTS to differentiate DR group from others was >5 (sensitivity of 85% and specificity of 57%, area under curve [AUC] 0.692, p=0.007), and that for worsening group was <4 (sensitivity of 96% and specificity of 59%, AUC 0.785, p<0.001). Multivariate regression analysis demonstrated that initial DWI-ASPECTS of >5 was significantly associated with DR (OR 9.75, 95%CI 1.41-67.67, p=0.021), and <4 with worsening (OR 15.94, 95%CI 4.01-63.25, p<0.001). Conclusion: DWI-ASPECTS can predict the short-term outcome in acute stroke patients with MCAO treated with IV-tPA.

Background and Purpose: Stroke is the first leading cause of death in China and millions of patients were admitted to various levels of hospitals each year. However, it is unknown how many of these hospitals are able to provide an appropriate level of care for stroke patients since the certification program of comprehensive stroke center (CSC) and primary stroke center (PSC) has not been initiated in China. Method: In 2012, we selected all 554 hospitals that joined into the China Stroke Research Network (CSRN) to start a survey. These hospitals were from 31 provinces or municipalities, covered nearly the entire Mainland China. A six-page questionnaire was sent to each of them to obtain the stroke facility information. We used the same criteria and definitions for CSC, PSC, and minimum level for any hospital ward (AHW) admitting stroke patients with that of the European Stroke Facilities Survey. Results: For all the hospitals in CSRN, 521 (94.0%) returned the questionnaire, 20 (3.8%) met criteria for CSC, 179 (34.4%) for PSC, 64 (12.3%) for AHW, and 258 (49.5%) met none of them and provided a lower level of care. Hospitals meeting criteria for CSC, PSC, AHW, and none of them admitted 70 052 (8.8%), 334 834 (42.2%), 88 364 (11.1%), and 299 806 (37.8%) patients in the whole of last year. There was no 24-hour availability for brain CT scan in 4.3% of hospitals not meeting criteria for AHW, while neither stroke care map nor stroke pathway for patients admission in 81.0% of them. Conclusions: Less than two fifths of Chinese hospitals admitting acute stroke patients have optimal facilities, and nearly half even the minimum level is not available. Our study suggests that only one half acute stroke patients are treated in appropriate centers in China, facilities for hospitals admitting stroke patients should be enhanced and certification project of CSCs and PSCs may be a feasible choice.

Introduction: Vascular imaging after head CT to confirm large vessel occlusion (LVO) for acute stroke patients requires additional time and delays recanalization. We developed the T hrombectomy A cute M echanical re P erfusion A ssessment ( TAMPA ) scale for selecting patients with LVO for direct angiosuite transfer and intervention to improve recanalization time. Methods: The TAMPA scale was developed from our prospectively collected “Get with the Guidelines” database. We included all “stroke alert” patients between 1/2017 and 8/2018 with vascular imaging and National Institutes of Health Stroke Scale scores between 5 and 25. We excluded patients with immediately obvious non-stroke diagnoses, those lacking subsequent vascular imaging, or those with incomplete records. Different variables were collected. The TAMPA scale receiver operating characteristics curve (ROC) was compared with the ROCs of other commonly used scales. Results: 571 eligible patients from 2115 “acute stroke alerts” were identified for developing the TAMPA scale. The scale was established with a combination of 5 items with a total score of 9: CT hyperdense sign, parenchymal hypodensity, lateralizing hemiparalysis, gaze deviation and speech disturbance. A cutoff of ≥ 4 yielded a sensitivity of 68.98%, specificity of 72.91%, false positive rate of 27.09%, and false negative rate of 31.02%. Compared with other scales, such as total NIHSS, C-stat/CPSSS, RACE, FAST-ED and 3I-SS, the TAMPA scale had the best ROC for the selected group of patients. Conclusions: The TAMPA scale accurately predicts presence of clinically amenable LVO in patients with moderate to severe ischemic stroke. Use of the TAMPA scale to identify high probability mechanical embolectomy candidates for direct transfer to the angiosuite could potentially reduce revascularization times and increase treatment rates.

Background Emergency Medical Services (EMS) is a vital link in the overall chain of stroke survival. A Primary Stroke Center (PSC) relies heavily on the 9-1-1 response system along with the ability of EMS personnel to accurately diagnose acute stroke. Other critical elements include identifying time of symptom onset, providing pre-hospital care, selecting a destination PSC, and communicating estimated time of arrival (ETA). Purpose Our purpose was to evaluate the EMS component of thrombolysed acute ischemic stroke patient care at our PSC. Methods In a retrospective manner we retrieved electronic copies of the EMS incident reports for every thrombolysed ischemic stroke patient treated at our PSC from September 2001 to August 2005. The following data elements were extracted: location of victim, EMS agency, times of dispatch, scene, departure, emergency department (ED) arrival, recordings of time of stroke onset, blood pressure (BP), heart rate (HR), cardiac rhythm, blood glucose (BG), Glasgow Coma Scale (GCS), Cincinnati Stroke Scale (CSS) elements, emergency medical personnel field assessment, and transport decision making. Results Eighty acute ischemic stroke patients received thrombolysis during the study interval. Eighty-one percent arrived by EMS. Two EMS agencies transported to our PSC. Mean dispatch-to-scene time was 6 min, on-scene time was 16 min, transport time was 10 min. Stroke onset time was recorded in 68%, BP, HR, and cardiac rhythm each in 100%, BG in 81%, GCS in 100%, CSS in 100%, and acute stroke diagnosis was made in 88%. Various diagnostic terms were employed: cerebrovascular accident in 40%, unilateral weakness or numbness in 20%, loss of consciousness in 16%, stroke in 8%, other stroke terms in 4%. In 87% of incident reports there was documentation of decision-making to transport to the nearest PSC in conjunction with pre-notification. Conclusion The EMS component of thrombolysed acute ischemic stroke patients care at our PSC appeared to be very good overall. Diagnostic accuracy was excellent, field assessment, decision-making, and transport times were very good. There was still room for improvement in documentation of stroke onset and in employment of a common term for acute stroke.
