The Impact

Introduction Controversies remain on whether post-stroke complications represent an independent predictor of poor outcome or just a reflection of stroke severity. We aimed to identify which post-stroke complications have the highest impact on in-hospital mortality by using machine learning techniques. Secondary aim was identification of patient’s subgroups in which complications have the highest impact. Patients and methods Registro Nacional de Ictus de la Sociedad Española de Neurología is a stroke registry from 42 centers from the Spanish Neurological Society. Data from ischemic stroke patients were used to build a random forest by combining 500 classification and regression trees, to weight up the impact of baseline characteristics and post-stroke complications on in-hospital mortality. With the selected variables, a logistic regression analysis was performed to test for interactions. Results 12,227 ischemic stroke patients were included. In-hospital mortality was 5.9% and median hospital stay was 7(4–10) days. Stroke severity [National Institutes of Health Stroke Scale > 10, OR = 5.54(4.55–6.99)], brain edema [OR = 18.93(14.65–24.46)], respiratory infections [OR = 3.67(3.02–4.45)] and age [OR = 2.50(2.07–3.03) for >77 years] had the highest impact on in-hospital mortality in random forest, being independently associated with in-hospital mortality. Complications have higher odds ratios in patients with baseline National Institutes of Health Stroke Scale <10. Discussion Our study identified brain edema and respiratory infections as independent predictors of in-hospital mortality, rather than just markers of more severe strokes. Moreover, its impact was higher in less severe strokes, despite lower frequency. Conclusion Brain edema and respiratory infections were the complications with a greater impact on in-hospital mortality, with the highest impact in patients with mild strokes. Further efforts on the prediction of these complications could improve stroke outcome.

The Impact

Objectives: Telestroke is the application of telemedicine to stroke care. We estimated the effect of participation in a telestroke network on in-hospital mortality in the state of Georgia, and explored its impact on mitigating the difference in mortality for patients admitted in nighttime compared to those admitted in daytime. Methods: We selected patients with ischemic stroke from 15 non-teaching hospitals in the Georgia’s Paul Coverdell Acute Stroke Registry from 2005 to 2016. We applied a quasi-experimental study design by classifying patients from 4 hospitals that participated in a telestroke network in 2009 as the treatment group, and patients from 11 hospitals that were not covered by the telestroke network as the comparison group. All selected hospitals are located in non-Metropolitan Areas. We compared mortality between treatment and comparison groups in 2005 - 2008 (pre-participation period for treatment group) and in 2009 - 2016 (post-participation period for treatment group), and estimated difference in in-hospital mortality attributable to participation in a telestroke network by applying a difference-in-differences approach, while adjusting for patients’ age, sex, race/ethnicity, insurance coverage, arrival mode, ambulatory status prior to the current stroke, stroke severity, medical history of atrial fibrillation/flutter and hospital admission time. Results: The mortality among ischemic stroke patients decreased in all selected hospitals over the last decade. Participation in a telestroke network significantly decreased in-hospital mortality by 3.2% (p-value= 0.003). There was a positive association between nighttime admission and in-hospital mortality in the entire patient sample. After controlling for the effect of participation in a telestroke network, the nighttime effect on mortality still remained significant (odds ratio=1.25, 95% confidence interval: 1.10 - 1.42). Conclusions: Acute ischemic stroke patients admitted in hospitals participating in a telestroke program had a more pronounced reduction in in-hospital mortality. However, telestroke coverage did not alter the effect of nighttime admission on in-hospital mortality.

The Impact

Background and Purpose: Clinical outcome and mortality after endovascular thrombectomy (EVT) in patients with ischemic stroke are commonly assessed after 3 months. In patients with acute kidney injury (AKI), unfavorable results for 3-month mortality have been reported. However, data on the in-hospital mortality after EVT in this population are sparse. In the present study, we assessed whether AKI impacts in-hospital and 3-month mortality in patients undergoing EVT.Materials and Methods: From a prospectively recruiting database, consecutive acute ischemic stroke patients receiving EVT between 2010 and 2018 due to acute large vessel occlusion were included. Post-contrast AKI (PC-AKI) was defined as an increase of baseline creatinine of ≥0.5 mg/dL or &gt;25% within 48 h after the first measurement at admission. Adjusting for potential confounders, associations between PC-AKI and mortality after stroke were tested in univariate and multivariate logistic regression models.Results: One thousand one hundred sixty-nine patients were included; 166 of them (14.2%) died during the acute hospital stay. Criteria for PC-AKI were met by 29 patients (2.5%). Presence of PC-AKI was associated with a significantly higher risk of in-hospital mortality in multivariate analysis [odds ratio (OR) = 2.87, 95% confidence interval (CI) = 1.16–7.13, p = 0.023]. Furthermore, factors associated with in-hospital mortality encompassed higher age (OR = 1.03, 95% CI = 1.01–1.04, p = 0.002), stroke severity (OR = 1.05, 95% CI = 1.03–1.08, p &lt; 0.001), symptomatic intracerebral hemorrhage (OR = 3.20, 95% CI = 1.69–6.04, p &lt; 0.001), posterior circulation stroke (OR = 2.85, 95% CI = 1.72–4.71, p &lt; 0.001), and failed recanalization (OR = 2.00, 95% CI = 1.35–3.00, p = 0.001).Conclusion: PC-AKI is rare after EVT but represents an important risk factor for in-hospital mortality and for mortality within 3 months after hospital discharge. Preventing PC-AKI after EVT may represent an important and potentially lifesaving effort in future daily clinical practice.

ASSOCIATION BETWEEN HISTORY OF HEART DISEASE AND SEVERITY OF ACUTE FIRST-EVER ISCHEMIC STROKEABSTRACTIntroduction: History of heart disease such as atrial  fibrillation, angina pectoris, myocardial infarction, heart failure has a role on ischemic stroke severity.Aim: This research aims to find the association between history of heart disease and stroke severity using NIHSS score on acute ischemic stroke patients in Atma Jaya hospital during 2014-2018.Method: This research used cross-sectional method with two-sided fisher’s exact test. With total sampling, samples retrieved from secondary sources in Atma Jaya hospital during 2014-2018 resulting 236 subjects. Stroke severity measured by NIHSS score during admission, categorized with severe stroke (15-42) and non-severe stroke (0-14).Result: There is a significant association between history of AF (p=0.046) on first-ever ischemic stroke severity. Acute first-ever ischemic stroke patients who are  >18 years old with history of AF has a tendency of 5,2 times to have severe stroke compared with patients without AF. Other history of heart disease has no significant association towards stroke severity.Discussion: In accordance with previous research, our findings suggest a significant association between history of atrial fibrillation and acute first-ever ischemic stroke severity in which there is a tendency of more severe stroke compared wth patients without AF. Unlike previous findings, this research shows no significant association between history of heart failure and stroke severity due to limited data characteristic  of ejection fraction preventing us to include patient with ejection fraction below 30%. This limitation may also allow history of angina pectoris and myocardial infarction to be insignificant.Keywords:  Atrial  fibrillation,  heart  failure,  ischemic  stroke,  myocardial  infarction,  National  Institutes  of Health Stroke ScaleABSTRAKPendahuluan: Riwayat penyakit jantung seperti atrial fibrilasi, angina pektoris, infark miokardium, gagal jantung memiliki peran terhadap keparahan stroke iskemik.Tujuan: Mengetahui hubungan riwayat penyakit jantung dengan tingkat keparahan stroke berdasarkan skor NIHSS pada pasien stroke iskemik akut di RS Atma Jaya pada tahun 2014-2018.Metode: Penelitian potong lintang terhadap data sekunder pasien stroke iskemik pertama kali yang dirawat di RS Atma Jaya pada tahun 2014-2018. Keparahan stroke diukur berdasarkan National Institutes of Health Stroke Scale (NIHSS) masuk dengan kategori severe stroke (skor 15-42) dan non-severe stroke (0-14).

Level Of Consciousness

Background: Impaired level of consciousness (LOC) on presentation after acute ischemic stroke (AIS) may affect outcomes and the decision to withdraw life-sustaining treatment (WLST). We aim to investigate the outcomes and their trends after AISby the LOC on stroke presentation. Methods: We studied 238,989 cases with AIS in the Florida Stroke Registry from 2010-2019. Pearson chi-squared and Kruskall-Wallis tests were used to compare descriptive statistics. A multivariable-logistic regression with GEE accounted for basic demographics, comorbidities, stroke severity, location, hospital size and teaching status. Results: At stroke presentation, 32,861 (14%) cases had impaired LOC (mean age 77, 54% women, 60 white%, 19% Black, 16% Hispanic). Compared to cases with preserved LOC, impaired cases were older (77 vs. 72 years old), more women (54% vs. 48%), had more comorbidities, greater stroke severity on NIHSS ≥ 5 (49% vs. 27%), higher WLST rates (3% vs. 0.6%), and greater in-hospital mortality rates (9% vs. 3%). In our adjusted model however, no significant association was found between impaired LOC and in-hospital mortality, or length of stay. Those with preserved LOC were more likely discharged home/rehab (OR 0.7, 95%CI 0.6-0.8, p<0.0001) and more likely to ambulate independently (OR 0.7, 95%CI 0.6-0.9, p=0.001). Trend analysis (2010-2019) showed decreased mortality, increased length of stay, and increased rates of discharge to home/rehab in all irrespective of LOC status. Conclusion: In this large multicenter registry, AIS cases presenting with impaired LOC had more severe strokes at presentation. Although LOC was not associated with significantly worse in-hospital morality, it was associated with higher rates of WLST and more disability among survivors. Future efforts should focus on biomarkers of LOC that discriminates the potential for early recovery and reduced disability in acute stroke patients with impaired LOC.

The Impact

The incidence of stroke has been a major task for medics and relatives globally. Stroke is the second most frequent disease with high morbidity as well as mortality worldwide. This is a very short and focus review on edaravone therapy. Due to the success story of edaravone in the management of stroke, it could be beneficial for severe stroke patients. The impact of edaravone was highest in the most severely afflicted stroke patients with National Institutes of Health Stroke Scale (NIHSS) scores ≥15 during admission. Large-artery atherosclerosis or cardioembolism stroke subtypes had the highest NIHSS scores. On the other hand, decompressive craniectomy is the resection of part of the skull so that edematous brain tissue can herniate outside. It is thus advocated that, edaravone therapy could be a substitute for decompressive craniotomy for large ischemic stroke in remote facilities with no neurosurgeons.

Protein Levels

Translocator protein 18 kDa (TSPO) has been used as a biomarker of brain injury and inflammation in various neurological diseases. In this study, we measured the level of TSPO in acute ischemic stroke patients and determined its association with the degree of stroke severity and its ability to predict stroke functional outcomes. In total, 38 patients with moderate to severe acute ischemic stroke were enrolled. Demographic information, cerebral risk factors, and stroke severity were examined at the baseline. The National Institutes of Health Stroke Scale, modified Rankin Scale, and Barthal Index were assessed at discharge as measures of poor functional outcomes and severe disability. The baseline fasting plasma TSPO level was assessed within 24 h after the incident stroke and during hospitalization (on days 8–10). The proportion of patients with poor functional outcomes was significantly higher in the higher-TSPO group (compared to the lower group) in terms of clinical worsening (odds ratio (OR) = 11.69, 95% confidence interval (CI) = 2.08–65.6), poor functional outcomes (OR = 10.5, 95% CI = 1.14–96.57), and severe disability (OR = 4.8, 95% CI = 1.20–19.13). Plasma TSPO may be intimately linked with disease progression and worse functional outcomes in acute ischemic stroke patients.

Background: stroke is the second leading cause of death and disability worldwide. The most significant factors for early mortality are age, severity of stroke (NIH stroke scale), atrial fibrillation (AF) and hypertension. Objective: elucidate the factors correlated with unfavorable outcome and mortality after ischemic stroke. Design/Setting: retrospective descriptive study conducted at the Botucatu Medical School Hospital. Methods: this study included 515 stroke patients, aged at least 18, admitted to ICU and stroke-unit between January/2017-December/2018. Baseline data, comorbidities and risk factors were collected and relation to unfavorable outcome and in-hospital mortality were evaluated. Unfavorable outcome was defined as dependency (modified Rankin Scale mRs 4–5). Results: overall, in-hospital mortality rate was 15% (77) and unfavorable outcome 36.7% (189). The patients average age was 69.18±13.08, and NIHSS at admission 9.27±8.41. NIHSS at admission and pre-morbid mRs were independently associated with unfavorable outcome, as each NIHSS point was responsible for 22% outcome increase. Both higher NIHSS and AF were independently associated with in-hospital mortality, increasing the death risk 19% and 3.5 times respectively. Conclusion: the main factor associated with overall in-hospital mortality and unfavorable outcome was stroke severity.

Background:Fatigue affects 33-77% of stroke survivors. There is no consensus concerning risk factors for fatigue post-stroke, perhaps reflecting the multifaceted nature of fatigue. We characterized post-stroke fatigue using the Fatigue Impact Scale (FIS), a validated questionnaire capturing physical, cognitive, and psychosocial aspects of fatigue.Methods:The Stroke Outcomes Study (SOS) prospectively enrolled ischemic stroke patients from 2001-2002. Measures collected included basic demographics, pre-morbid function (Oxford Handicap Scale, OHS), stroke severity (Stroke Severity Scale, SSS), stroke subtype (Oxfordshire Community Stroke Project Classification, OCSP), and discharge function (OHS; Barthel Index, BI). An interview was performed at 12 months evaluating function (BI; Modified Rankin Score, mRS), quality of life (Reintegration into Normal living Scale, RNL), depression (Geriatric Depression Scale, GDS), and fatigue (FIS).Results:We enrolled 522 ischemic stroke patients and 228 (57.6%) survivors completed one-year follow-up. In total, 36.8% endorsed fatigue (59.5% rated one of worst post-stroke symptoms). Linear regression demonstrated younger age was associated with increased fatigue frequency (β=-0.20;p=0.01), duration (β=-0.22;p<0.01), and disability (β=-0.24;p<0.01). Younger patients were more likely to describe fatigue as one of the worst symptoms post-stroke (β=-0.24;p=0.001). Younger patients experienced greater impact on cognitive (β=-0.27;p<0.05) and psychosocial (β=-0.27;p<0.05) function due to fatigue. Fatigue was correlated with depressive symptoms and diminished quality of life. Fatigue occurred without depression as 49.0% of respondents with fatigue as one of their worst symptoms did not have an elevated GDS.Conclusions:Age was the only consistent predictor of fatigue severity at one year. Younger participants experienced increased cognitive and psychosocial fatigue.

Background Limited national-level information on temporal trends in comprehensive stroke center capabilities and their effects on acute ischemic stroke patients exists. Aims To examine trends in in-hospital outcomes of acute ischemic stroke patients and the prognostic influence of temporal changes in comprehensive stroke center capabilities in Japan. Methods This retrospective study used the J-ASPECT Diagnosis Procedure Combination database and identified 372,978 acute ischemic stroke patients hospitalized in 650 institutions between 2010 and 2016. Temporal trends in patient outcomes and recombinant tissue plasminogen activator (rt-PA) and mechanical thrombectomy usage were examined. Facility comprehensive stroke center capabilities were assessed using a validated scoring system (comprehensive stroke center score: 1–25 points) in 2010 and 2014. The prognostic influence of temporal comprehensive stroke center score changes on in-hospital mortality and poor outcomes (modified Rankin Scale: 3–6) at discharge were examined using hierarchical logistic regression models. Results Over time, stroke severity at admission decreased, whereas median age, sex ratio, and comorbidities remained stable. The median comprehensive stroke center score increased from 16 to 17 points. After adjusting for age, sex, comorbidities, consciousness level, and facility comprehensive stroke center score, proportion of in-hospital mortality and poor outcomes at discharge decreased (from 7.6% to 5.0%, and from 48.7% to 43.1%, respectively). The preceding comprehensive stroke center score increase (in 2010–2014) was independently associated with reduced in-hospital mortality and poor outcomes, and increased rt-PA and mechanical thrombectomy use (odds ratio (95% confidence interval): 0.97 (0.95–0.99), 0.97 (0.95–0.998), 1.07 (1.04–1.10), and 1.21 (1.14–1.28), respectively). Conclusions This nationwide study revealed six-year trends in better patient outcomes and increased use of rt-PA and mechanical thrombectomy in acute ischemic stroke. In addition to lesser stroke severity, preceding improvement of comprehensive stroke center capabilities was an independent factor associated with such trends, suggesting importance of comprehensive stroke center capabilities as a prognostic indicator of acute stroke care.
