Tirofiban combined with heparin's effect and safety in the treatment of mild to moderate acute ischemic stroke.
Authors: Qiu T, Li C, Huang L, Xiao H, Deng X, Dai X, Fu S, Wang J, Gong Q, Luo Q, Wang M, He W, Chen M Abstract Tirofiban can be used to treat patients with acute ischemic stroke (AIS), this study was to evaluate the efficacy and safety of tirofiban combined with heparin in the treatment of mild to moderate AIS. A total of 98 patients with mild to moderate AIS randomly were divided into 2 groups within 48 h: the treatment group treated with tirofiban and, and the control group treated with aspirin + clopidogrel. The treatment group was given the same scheme as the control group after the treatment of tirofiban co...

Clinical characteristics of inpatients with Coronavirus disease 2019 and acute ischemic stroke: from epidemiology to outcomes.
This article will elaborate on the clinical features of inpatients with COVID-19 and AIS and the pathophysiological mechanism of AIS under the background of COVID-19. Through a detailed search of relevant studies, we found that the incidence of AIS among COVID-19 patients varied from 0.9% to 4.6%, and AIS has been observed in many people without underlying diseases and cardiovascular risk factors as well as young people. The National Institute of Health Stroke Scale (NIHSS) score of COVID-19 patients with AIS was higher than historical AIS patients, and the proportion of large vessel occlusion (LVO) was about 64.2%. COVID-...

Nomogram Including Neutrophil-to-Lymphocyte Ratio for the Prediction of Stroke-Associated Infections
Stroke has been a leading cause of mortality in China. Stroke-associated infections (SAI) are common complications, occurring in 5–65% of stroke patients. Faced with SAI, clinicians often are placed in a considerable dilemma. On the one hand, preventive overuse of antibiotics will lead to the emergence of drug-resistant bacteria. On the other hand, treatment delay of the infection will likely result in a poor outcome. Therefore, it is necessary to determine the early predictors of post-stroke infection to screen patients with high infection risk for early clinical intervention, thereby promoting and improving survival ra...

Admission blood cell counts are predictive of stroke-associated infection in acute ischemic stroke patients treated with endovascular therapy
AbstractStroke-associated infection (SAI) is a major medical complication in acute ischemic stroke patients (AIS) treated with endovascular therapy (EVT). Three hundred thirty-three consecutive patients with AIS caused by a large vessel occlusion in the anterior circulation who received EVT (142 (42.6%) of them were given IV tPA as bridging therapy) and 337 AIS patients who received IV tPA only (non-EVT) were enrolled in the study and evaluated to determine the association of inflammatory factors on admission with SAI. Among the 333 AIS patients undergoing EVT, SAI occurred in 219 (65.8%) patients. Patients with SAI had hi...

Iodinated Contrast Agents Reduce the Efficacy of Intravenous Recombinant Tissue-Type Plasminogen Activator in Acute Ischemic Stroke Patients: a Multicenter Cohort Study
This study aimed to investigate whether the application of iodinated contrast agents before intravenous (IV) recombinant tissue plasminogen activator (rt-PA) reduces the efficacy in acute ischemic stroke (AIS) patients. To determine whether the application of iodinated contrast agents before intravenous rt-PA reduces the efficacy in AIS patients. We analyzed our prospectively collected data of consecutive AIS patients receiving IV rt-PA treatment in the MISSION CHINA study. Clinical outcome at 3  months was assessed with modified Rankin Scale (mRS) score and dichotomized into good outcome (0–2) and poor outcome (3–6)....

Metabolic syndrome is associated with cognitive impairment after transient ischemic attack/mild stroke, but does not affect cognitive recovery in short term
The metabolic syndrome (MetS) is a cluster of risk factors for cognitive impairment. We aimed to investigate the association between MetS and risk of persistent cognitive impairment in patients with a transient ischemic attack (TIA) or mild ischemic stroke. This is a prospective and observational study in consecutive patients with first-ever TIA or mild stroke (National Institutes of Health Stroke Scale score ≤ 6). Patients underwent Montreal cognitive assessment (MoCA) at hospital admission and day 30 after discharge. We defined cognitive impairment as a MoCA score of ≤26. Persistent cognitive impairment was defin...

Intravenous Thrombolysis Benefits Mild Stroke Patients With Large-Artery Atherosclerosis but No Tandem Steno-Occlusion
In this study, we therefore sought to determine whether the therapeutic benefit of thrombolysis is dependent upon stroke subtype for those with mild stroke. We conducted a retrospective analysis of data from consecutive mild stroke patients (National Institutes of Health Stroke Scale ≤5) with and without recombinant tissue plasminogen activator (rt-PA) therapy. The TOAST (Trial of Org 10172 in acute stroke treatment) criteria was used to determine stroke subtypes. Patients suffering from large-artery atherosclerosis (LAA) were subdivided based upon whether or not they exhibited tandem steno-occlusion, as defined by the a...

Importance of the Intention-to-Treat Principle
To the Editor The recent study by Goyal et al represents the third largest cohort study on patients with large vessel occlusions (LVOs) who present with mild deficits (National Institutes of Health Stroke Scale score, 0-5) and, to our knowledge, the largest meta-analysis regarding this topic. This highlights the growing interest on how to optimally treat such patients.

Challenges of Thrombolysis in a Developing Country: Characteristics and Outcomes in Peru
Background: The availability of intravenous tissue plasminogen activator (IV-tPA) remains limited worldwide, especially in low-income countries, where the burden of disability due to ischemic stroke is the highest. Aims: To evaluate outcomes and safety of IV-tPA at the only Peruvian reference institute for neurologic diseases. Methods: We conducted a prospective, observational study of stroke patients who received IV-tPA between 2009 and 2016. We assessed characteristics associated with good outcome (modified Rankine scale 0-2) at 3 months using a multivariate regression model; and factors correlated with clinical improvem...

Altered static and dynamic voxel-mirrored homotopic connectivity in subacute stroke patients: a resting-state fMRI study
AbstractSixty-four subacute stroke patients and 55 age-matched healthy controls (HCs) underwent a resting-state functional magnetic resonance imaging scan using an echo-planar imaging sequence and high-resolution sagittal T1-weighted images using a three-dimensional magnetization-prepared rapid gradient echo sequence. Static and dynamic voxel-mirrored homotopic connectivity (VMHC) was computed, respectively. The relationships between the clinical measures, including National Institutes of Health Stroke Scale (NIHSS), illness duration, Fugl-Meyer assessment for upper and lower extremities (FMA-total) and size of lesion volu...

Low Levels of Glycemia within the First 48 Hours after Mechanical Thrombectomy for Acute Ischemic Stroke May be Associated with Better Clinical Outcome
Introduction: Many different factors may have an impact on clinical outcome after mechanical thrombectomy (MT) for acute ischemic stroke (AIS). We aimed to investigate levels of serum glycemia (GLY) within the first 48 hours after MT. Subjects and Methods: Consecutive AIS patients were enrolled in the retrospective bi-center study. Neurological deficit was assessed with National Institutes of Health Stroke Scale (NIHSS) and functional outcome after 3 months with modified Rankin scale with a score 0-2 for good outcome.

The Association Between Serum Apelin-13 and the Prognosis of Acute Ischemic Stroke
AbstractWhile a number of studies have reported an association between apelin-13 and ischemic stroke, few have verified its clinical effect. We investigated the prognostic value of serum apelin-13 levels in patients with acute ischemic stroke (AIS). We prospectively recruited 244 AIS patients within 24  h after stroke onset, and 167 healthy controls. We assessed the serum apelin-13 levels using ELISA, and the severity of AIS using the National Institutes of Health Stroke Scale (NIHSS). The primary outcomes included death or major disability (modified Rankin Scale score, 3–6) and major disabilit y (modified Rankin Scale ...
