Background: Accurate prognostication of unfavorable outcome made at the early onset of stroke is important to both the clinician and the patient management. This study was aimed to develop a nomogram based on the integration of parameters to predict the probability of 3-month unfavorable functional outcome in Chinese acute ischemic stroke patients. Methods: We retrospectively collected patients who underwent acute ischemic stroke at Stroke Center of the Nanjing First Hospital (China) between May 2013 and May 2018. After exclusion, the study population includes 1,025 patients for nomogram development. The main outcome measure was 3-month unfavorable outcome (modified Rankin Scale > 2). Multivariable logistic regression analysis was used to develop the predicting model, and stepwise logistic regression with the Akaike information criterion was utilized to find best-fit nomogram model. We incorporated the creatinine, fast blood glucose, age, previous cerebral hemorrhage, previous valvular heart disease, and NHISS score (COACHS), and these factors were presented with a nomogram. We assessed the discriminative performance by using the area under curve (AUC) of receiver-operating characteristic (ROC) and calibration of risk prediction model by using the Hosmer-Lemeshow test. Results: Multivariate analysis of the 1,025 patients for logistic regression helped identify the independent factors as National Institutes of Health Stroke Scale score on admission, age, previous valvular heart disease, fasting blood glucose, creatinine, and previous cerebral hemorrhage, which were included in the COACHS nomogram. The AUC-ROC of nomogram was 0.799. Calibration was good (p = 0.1376 for the Hosmer-Lemeshow test). Conclusions: The COACHS nomogram may be used to predict unfavorable outcome at 3 months after acute ischemic stroke in Chinese population. It may be also a reliable tool that is effective in its clinical utilization to risk-stratify acute stroke patients.

Abstract Background Insulin resistance is associated with the occurrence of stroke and atherosclerotic disease. However, the relationship between insulin resistance and the prognosis of acute ischemic stroke in nondiabetic patients is unclear. We hypothesized that insulin resistance may affect short-term functional recovery after acute ischemic stroke in nondiabetic patients. Methods Between May 2014 and December 2016, 1377 consecutive patients with acute ischemic stroke were enrolled from a prospectively maintained stroke registry. After excluding patients with transient ischemic attacks (TIA), pre-stroke disabilities, diabetes mellitus, and patients with incomplete evaluations, 517 patients were included in the study. The homeostasis model assessment of insulin resistance (HOMA-IR) score was used to evaluate the degree of insulin resistance. The factors associated with poor functional outcomes were analyzed using multivariate logistic regression. Results The patients with the highest quartile of log HOMA-IR index scores were younger and had higher fasting blood glucose, total cholesterol, triglycerides, low-density lipoprotein, and HbA1c levels. Multivariate logistic regression analysis revealed that log HOMA-IR scores were independently associated with poor prognosis after adjusting for age and sex and p < 0.1 in univariate analysis. Conclusion Insulin resistance measured by the HOMA-IR index was associated with the poor functional outcome of non-diabetic stroke patients. This evidence supports treating insulin resistance in acute ischemic stroke patients with blood glucose levels within the normal range.

ABSTRACT Objective We aimed to develop a model to predict unfavorable outcome in patients with acute ischemic stroke treated with intravenous thrombolytic therapy (IVT), based on simple variables present on admission. Methods Retrospective analysis of acute ischemic stroke patients treated with IVT in a hospital in Rio de Janeiro. Clinical and radiographic variables were selected for analysis. Multivariate logistic regression was used to develop a predictive model. Results We analyzed a total of 82 patients. Median National Institutes of Health Stroke Scale (NIHSS) on admission was 9 (3–22), 40.2% presented with a hyperdense artery sign (HAS), 62% had identifiable early parenchymal changes and 61.6% experienced a favorable outcome. An NIHSS score of > 12 on arrival, age > 70 and the presence of HAS were associated with the outcome, even after correction in a logistic regression model. Conclusion An NIHSS > 12 on arrival, presence of HAS and age > 70 years were predictors of unfavorable outcome at three months in patients with acute ischemic stroke treated with IVT.

BACKGROUND: Although hyperglycemia in acute stroke is associated with poor stroke outcomes, it remains unclear whether blood glucose variability are also associated with stroke outcomes. In this study, we examined the relationships between daily blood glucose variability and early neurological outcome in acute ischemic stroke patients with diabetes mellitus. METHODS: Subjects were a total of 329 acute ischemic stroke patients (216 male, 70.9 ± 9.6 years) who were either already undergoing treatment for diabetes or had a hemoglobin A1c level of >5.8% at admission from July 2006 to June 2009. The consecutive morning fasting blood glucose (BG) levels were evaluated during 7 days from admission and described as mean and successive variation (SV). The unfavorable outcome was defined by a modified Rankin Scale score of 4 to 6 at discharge. RESULTS: The patients with unfavorable outcome (n=86) were older (75.7 ± 10.5 vs. 69.2 ± 8.6 years, p<0.001), more frequently female (47.7% vs. 29.6%, p=0.003), less commonly had dyslipidemia (40.7% vs. 60.9%, p=0.001), less commonly took oral hypoglycemic agents (30.2% vs. 53.5%, p<0.001), and had higher NIHSS scores (median 9 vs. 3, p<0.001) than those without. The mean BG levels and SV levels in patients with unfavorable outcome were higher than those in patients without (163.3 ± 39.0 vs. 147.9 ± 34.0 mg/dl; p<0.001 and 33.7 ± 24.9 vs. 23.2 ± 15.3 mg/dl; p<0.001, respectively). SV levels was independently associated with unfavorable outcome (OR 1.023, 95%CI 1.004-1.042, p=0.015) using logistic regression analysis controlling age, sex hypertension systolic blood pressure, NIHSS score at admission and insulin use during hospitalization, which are selected using stepwise method. However mean BG levels did not remained as factor, which associated with unfavorable outcome with step wise method. CONCLUSION: Increased blood glucose variability, but not mean BG, was independently related to unfavorable outcome at discharge in acute ischemic stroke patients with diabetes mellitus.

Background: Dysphagia is associated with poor outcome in stroke patients. Studies investigating the association of dysphagia and early dysphagia screening (EDS) with outcomes in patients with acute ischemic stroke (AIS) are rare. The aims of our study are to investigate the association of dysphagia and EDS within 24 h with stroke-related pneumonia and outcomes. Methods: Over a 4.5-year period (starting November 2007), all consecutive AIS patients from 15 hospitals in Schleswig-Holstein, Germany, were prospectively evaluated. The primary outcomes were stroke-related pneumonia during hospitalization, mortality, and disability measured on the modified Rankin Scale ≥2-5, in which 2 indicates an independence/slight disability to 5 severe disability. Results: Of 12,276 patients (mean age 73 ± 13; 49% women), 9,164 patients (74%) underwent dysphagia screening; of these patients, 55, 39, 4.7, and 1.5% of patients had been screened for dysphagia within 3, 3 to <24, 24 to ≤72, and >72 h following admission. Patients who underwent dysphagia screening were likely to be older, more affected on the National Institutes of Health Stroke Scale score, and to have higher rates of neurological symptoms and risk factors than patients who were not screened. A total of 3,083 patients (25.1%; 95% CI 24.4-25.8) had dysphagia. The frequency of dysphagia was higher in patients who had undergone dysphagia screening than in those who had not (30 vs. 11.1%; p < 0.001). During hospitalization (mean 9 days), 1,271 patients (10.2%; 95% CI 9.7-10.8) suffered from stroke-related pneumonia. Patients with dysphagia had a higher rate of pneumonia than those without dysphagia (29.7 vs. 3.7%; p < 0.001). Logistic regression revealed that dysphagia was associated with increased risk of stroke-related pneumonia (OR 3.4; 95% CI 2.8-4.2; p < 0.001), case fatality during hospitalization (OR 2.8; 95% CI 2.1-3.7; p < 0.001) and disability at discharge (OR 2.0; 95% CI 1.6-2.3; p < 0.001). EDS within 24 h of admission appeared to be associated with decreased risk of stroke-related pneumonia (OR 0.68; 95% CI 0.52-0.89; p = 0.006) and disability at discharge (OR 0.60; 95% CI 0.46-0.77; p < 0.001). Furthermore, dysphagia was independently correlated with an increase in mortality (OR 3.2; 95% CI 2.4-4.2; p < 0.001) and disability (OR 2.3; 95% CI 1.8-3.0; p < 0.001) at 3 months after stroke. The rate of 3-month disability was lower in patients who had received EDS (52 vs. 40.7%; p = 0.003), albeit an association in the logistic regression was not found (OR 0.78; 95% CI 0.51-1.2; p = 0.2). Conclusions: Dysphagia exposes stroke patients to a higher risk of pneumonia, disability, and death, whereas an EDS seems to be associated with reduced risk of stroke-related pneumonia and disability.

Cognitive decline is a significant complication that affects most stroke survivors. Early detection of cognitive decline in ischemic stroke patients and identification of risk factors improves their clinical outcomes. This study aimed to determine the characteristics of cognitive status in the sub-acute phase of ischemic stroke. A cross-sectional study was conducted on 89 sub-acute ischemic stroke patients in three hospitals in West Nusa Tenggara recruited consecutively from August 2019 to April 2020. The data collected were demographic and clinical characteristics, cognitive status, and functional outcome. The association between clinical and demographic characteristics and cognitive decline was analyzed using logistic regression. In addition, the relationship between cognitive status and functional outcomes of these patients was examined using the chi-square test. This study revealed that the prevalence of cognitive decline in these subjects was 71.9%. Multiple logistic regression showed that age was the only characteristic associated with cognitive decline in the subjects (OR = 5.12,95% CI = 1.08-24.28). Furthermore, the frequency of cognitive decline in these subjects was significantly associated with functional outcomes (p-value =0.014). Thus, there was a high prevalence of cognitive decline in sub-acute ischemic stroke patients associated with increasing age and poor functional outcomes.

Abstract Background: Stroke-associated pneumonia (SAP) is a major complication after stroke, oral microorganisms are important contributors to SAP. Here, we aimed to investigate whether the oral hygiene was associated with SAP and related risk factors of them in patients with acute ischemic stroke. Methods: We performed a cross-sectional study that recruited 331 patients with acute ischemic stroke from two medical centers. A series of assessments were performed to evaluate the neurological status and habits of oral hygiene. According to whether the oral hygiene was abnormal and SAP occurred, univariate analyses were performed in cohort 1 (normal / abnormal oral hygiene groups) and cohort 2 (SAP / non-SAP groups). Multiple logistic regression analyses were conducted to confirm risk factors of oral cleanliness and SAP in stroke patients. Results: A total of 12 and 8 independent variables were included in the model 1 and 2 analysis. After adjusting for confounders, multivariable logistic regression analysis showed that oral cleanliness was not only closely related to SAP (OR=2.219, P=0.026), dental caries (OR=1.292, P=0.005) and age (OR=1.030, P=0.006) in model 1, but also an independent risk factor for predicting SAP (OR=1.678, P=0.001) in model 2. Barthel index was a protective factor for oral cleanliness (OR=0.986, P=0.019) and SAP (OR=0.977, P=0.002) in ischemic stroke patients. Conclusions: Mutually primary risk roles of abnormal oral cleanliness and SAP exist in patients with acute ischemic stroke. Dental caries and aging are important risk factors for oral health disorders. Improving the activities of daily living would have protective effects on both oral hygiene and SAP prevention in stroke patients.

Background and Purpose: Hyperintense vessel sign on FLAIR (HVS) has been described in hyperacute stroke patients with arterial occlusion. It’s a surrogate marker for stroke severity in patients with acute ischemic stroke of the anterior circulation. We aimed to reveal the clinical significance of HVS in patients with acute posterior circulation infarction. Methods: This observational study is based on a single-center prospective registry study. Inclusion criteria were: symptomatic ischemic stroke patients who have lesions only in posterior circulation; and taken initial MRI within 14 days from onset.An unfavorable outcome was defined as mRS score of 2 to 6 at 3 months from the onset. First investigation is to estimate whether HVS could be related to the subtype of acute ischemic stroke (cohort A). Second, the correlation between HVS and mRS at 3 months was evaluated (cohort B). Results: From October 2012 to May 2019, consecutive 1,079 ischemic stroke subjects were screened, including 277 in cohort A (191 male, median age 64 years) and 240 in cohort B (165 male, median age 66 years, Figure A). In cohort A, HVS was independently associated with intracranial artery dissection (OR 5.228; 95% CI 2.270-12.039; p = 0.001) and large-artery atherosclerosis (OR 3.582; 95% CI 1.244-10.317; p = 0.018, Figure B). In cohort B, HVS was not a factor independently associated with unfavorable outcome (OR 2.925; 95% CI 0.881-9.714; p = 0.080). Conclusions: HVS in patients with posterior circulation infarct suggests intracranial artery dissection or large-artery atherosclerosis, but does not have impact on their clinical courses.
