Association between Serum Insulin-Like Growth Factor-1 and Neurological Severity in Acute Ischemic Stroke

Background and PurposeSerum insulin-like growth factor-1 (IGF-1) is known to have a neuroprotective effect. This study aimed to determine the effects of serum IGF-1 on the severity and clinical outcome of acute ischemic stroke (AIS).MethodsThis study included 446 patients with AIS who were admitted to Hallym University Sacred Heart Hospital within 7 days of stroke onset from February 2014 to June 2017. Serum IGF-1 levels were measured within 24 hours of admission. Stroke severity was measured using the National Institutes of Health Stroke Scale (NIHSS) score at admission, and the functional outcome at 3 months after symptom onset was assessed using the modified Rankin Scale score. The effects of serum IGF-1 levels on stroke severity and 3-month functional outcomes were analyzed using multivariate logistic regression analysis.ResultsThis study evaluated 379 patients with AIS (age 67.2±12.6 years, mean±standard deviation; 59.9% males) after excluding 67 patients who had a history of previous stroke (n=25) or were lost to follow-up at 3 months (n=42). After adjusting for clinically relevant covariates, a higher serum IGF-1 level was associated with a lower NIHSS score at admission (adjusted odds ratio=0.44, 95% confidence interval=0.24–0.80, p=0.01), while there was no significant association at 3 months.ConclusionsThis study showed that a higher serum IGF-1 level is associated with a lower NIHSS score at admission but not at 3 months. Further studies are required to clarify the usefulness of the serum IGF-1 level as a prognostic marker for ischemic stroke.

Relationships between Alcohol Intake and Ischemic Stroke Severity in Sex Stratified Analysis for Japanese Acute Stroke Patients

BackgroundThe aim of this study is to evaluate in the relationships between alcohol intake and ischemic stroke severity in Japanese stroke patients.MethodsOf a total of 101,165 registered cases of stroke in Japan, patient data of total strokes (n = 60,836), cardiogenic strokes (n = 11,894), and noncardiogenic strokes (n = 29,129) were extracted. The National Institutes of Health Stroke Scale (NIHSS) score at admission and the modified Rankin Scale (mRS) score at discharge were used. Significant alcohol consumption in regard to stroke severity at admission and discharge was identified by multivariate adjusted logistic regression analysis.ResultsAmong all subject and males, nondrinkers had significantly poorer NIHSS scores of cardiogenic strokes as did those consuming greater than or equal to 60 g/day, whereas there was a significant difference in past heavy drinkers with noncardiogenic strokes. Among females, nondrinkers had a significance of cardiogenic stroke and non-cardiogenic strokes. Among all subjects and males, 20-39 g/day and 40-59 g/day were significantly associated with protective effects on mRS severity of cardiogenic strokes, whereas 40-59 g/day also had significant protective effects for noncardiogenic strokes. Among females, greater than or equal to 60 g/day had a significant protective effect for cardiogenic strokes.ConclusionsFor males, alcohol intake of less than 60 g/day played a protective role in functional prognosis at discharge and showed a J-shape relationship. For females, although there was a limitation that the number of female drinkers was small, negative effects were shown at admission with less consumption than males.     

Association between Histone Deacetylase 9 Gene Polymorphism and Stroke in Chinese Han Population

ObjectiveTo explore the correlation between the polymorphism of histone deacetylase 9 gene (rs1060499865, rs723296, rs957960) and ischemic stroke (IS) in Chinese Han population in Dali region. MethodsThis study included 155 IS patients and 128 healthy physical examinees. TaqMan-polymerase chain reaction technology and multivariate logistic regression were performed. ResultsIn the case group, there was no polymorphism of rs1060499865 observed in the two groups; whereas on the rs723296 locus the frequencies of C allele and TC genotype were significantly higher than that in the control group, alleles C and T were associated with a 2.158-fold increase in IS risk, and genotypes TC and TT were associated with a 2.269-fold increase in IS risk. The locus rs957960 exhibited no significant difference between the two groups. ConclusionAn association between rs723296 and the risk of IS was found in the Chinese Han population in Dali region. No significant association was found between rs1060499865, rs957960 and IS in the Chinese Han population in Dali region.     

Association Between Troponin Levels and Visceral Infarction in Patients with Acute Ischemic Stroke

BackgroundVisceral infarctions appear to be more common in patients with embolic stroke subtypes, but their relation to troponin elevation remains uncertain.MethodsAmong patients with acute ischemic stroke enrolled in the Cornell AcutE Stroke Academic Registry (CAESAR) from 2011 to 2016, we included those with troponin measured within 24 hours from stroke onset and a contrast-enhanced abdominal computed tomographic scan within 1 year of admission. A troponin elevation was defined as a value exceeding our laboratory's upper limit of normal (.04 ng/ mL) in the absence of a clinically recognized acute ST-segment elevation myocardial infarction. Visceral infarction was defined as a renal or splenic infarction as ascertained by a single radiologist blinded to patients’ other characteristics. Multivariable logistic regression was used to evaluate the association between elevated troponin and visceral infarction.ResultsAmong 2116 patients registered in CAESAR from 2011 to 2016, 153 patients had both a troponin assay and a contrast-enhanced abdominal computed tomographic scan, of whom 33 (21%) had an elevated troponin and 22 (14%) had a visceral infarction. The prevalence of visceral infarction was higher among patients with an elevated troponin (30%; 95% confidence interval [CI], 16%-49%) than among patients without an elevated troponin (10%; 95% CI, 5%-17%) (P = .003). After adjustment for demographics and comorbidities, we found a significant association between elevated troponin and visceral infarction (odds ratio, 3.9; 95% CI, 1.5-10.4).ConclusionsAmong patients with acute ischemic stroke, elevated troponin was associated with visceral infarction. Our results demonstrate that poststroke troponin elevation may indicate the presence of underlying embolic sources.

The Effect of C-Reactive Protein on Functional Outcome in Ischemic Stroke patients

This study was performed to evaluate the effect of C-reactive protein (CRP) measured within 24 hr after stroke onset on functional outcome in ischemic stroke patients. The medical records of 28 first-ever hemiplegic ischemic stroke patients with the lesions on the middle cerebral arterial territory were reviewed. Subjects were classified into experimental group (serum CRP ≥ 0.5 mg/dL) and control group (serum CRP < 0.5 mg/dL) based on the level of serum CRP measured within 24 hr after stroke onset. Serum CRP measured within 24 hr after stroke onset was significantly correlated with functional scales in ischemic stroke patients.     

Association between Mapuche Ethnicity and Stroke: A Case-Control Study

Background: There is evidence of a greater incidence of stroke in native populations and minorities. A total of 34% of the population in the Araucanía Region is indigenous. The association between Mapuche ethnicity and stroke is unknown. The aim of the study was to estimate the magnitude of the association between Mapuche ethnicity and stroke occurrence in patients admitted to the Dr. Hernán Henríquez Aravena Hospital (HHHA) in Temuco, Chile. Methods: We performed an incident case–control-paired study with patients hospitalized with an acute stroke in the internal medicine service and controls from other medical services at the HHHA. One control was selected for each case, matched by gender and age (±5 years). Results: A total of 104 nonconsecutive cases of stroke were included. The proportion of Mapuche individuals was similar between cases and controls (27.9% and 32.7%, respectively, P = .45). Hypertension and overweight-obesity were associated with stroke. Low socioeconomic status, rurality, diabetes, and smoking were associated with Mapuche ethnicity. In the conditional logistic regression model, Mapuche ethnicity was not associated with stroke. The odds ratio was .75 (P = .47, 95% confidence intervals: .35-1.62). Conclusions: There is no statistically significant evidence in the study to support the hypothesis of an association between Mapuche ethnicity and stroke. None of the control variables modified the effect of ethnicity on stroke.
