Identifying Gaps and Missed Opportunities for Intravenous Thrombolytic Treatment of Inpatient Stroke
Background: Inpatient stroke-codes (ISC) have traditionally seen low treatment rates with IV-thrombolytic (IVT). The purpose of this study was to identify the predictors of true stroke, prevalent IVT-treatment gap and study the factors associated with such missed treatment opportunities (MTO).Methods: A retrospective chart review identified ISC from March 2017 to March 2018. Clinical, radiographic and demographic data were collected. Primary analysis was performed between stroke vs. non-stroke diagnoses. Dichotomous variables were analyzed using Chi-Square test of proportions and continuous variables with Wilcoxon-Ranked-Sum test. Significant factors were then tested in a multivariate logistic regression model for independence.Results: From 211 ISC, 36% (n = 76) had an acute stroke. Hemorrhagic stroke (HS) was present in 5.7% (n = 12). Of the remaining 199, 44% (n = 87) were IVT-eligible but only 3.4% (n = 3) were treated. Of the remaining 84 IVT-eligible-but-untreated patients, 69(82.1%) were mimics, while 15 (17.9%) had an ischemic stroke (IS), constituting a MTO of 1 in 6 IVT-eligible patients, with National Institutes of Health Stroke Scale (NIHSS) ≤4 being the commonest deterrent. Independent predictors of stroke were ejection fraction (EF)
In conclusion, available evidence from aggregate data supported a modest advantage of ticagrelor-involving regimens for the primary stroke prevention in CAD compared with other antiplatelet regimens after the trade-off between reducing IS and inducing ICH, where more benefits might be expected from long-term and low-dose use of tica grelor among patients with chronic coronary syndrome. Further collaborative meta-analysis of individual participant data from well-designed and statistically-powered trials would be needed to generate high quality evidence on this issue.
ConclusionsThis retrospective study suggests that SHPD may play a protective role in HT appearance and evolution, which requires verification by a randomized clinical trial.
CONCLUSIONS: The prevalence of stroke in this cohort was 3.1%. Ischemic strokes had a bimodal presentation, occurring either early after SLE diagnosis or after a several-year delay. Half of the hemorrhagic strokes occurred>10 years after the diagnosis of SLE. Clinical outcome was usually good with a relatively low recurrence rate.

Abstract Thrombolytic therapy with recombinant tissue plasminogen activator (rtPA) in ischaemic stroke has been associated with neurotoxicity, blood brain barrier (BBB) disruption and intra-cerebral hemorrhage. To examine rtPA cellular toxicity we investigated the effects of rtPA on cell viability in neuronal, astrocyte and brain endothelial cell (bEnd.3) cultures with and without prior exposure to oxygen-glucose deprivation (OGD). In addition, the neuroprotective peptide poly-arginine-18 (R18D; 18-mer of D-arginine) was examined for its ability to reduce rtPA toxicity. Studies demonstrated that a 4- or 24-h expos...
CONCLUSIONS: Prior stroke and atrial fibrillation are independent risk factors for early ICHs (within 12 h) after intravenous thrombolysis with alteplase. PMID: 32115471 [PubMed - as supplied by publisher]
Conclusion: The clinical guidelines are still the main reference for guiding clinical practice, and the main thrombolytic standards and contraindications for treatment still need to be conformed. On this basis, for individualized patients, clinicians must accurately judge the cause of acute stroke, to make optimal choice, reduce disability and mortality, and improve quality of life of patients.
AbstractThere were limited studies comparing the anterior (AC) and posterior (PC) circulation acute ischemic strokes (AIS). Our study aimed to evaluate distinct features of AC and PC strokes regarding clinical, vascular risk, pathogenesis and outcome factors after endovascular procedures. This multicenter prospective study registered 873 patients with acute large occlusion of anterior circulation stroke (ACS) and posterior circulation stroke (PCS). Patients who underwent endovascular procedures were included in this study. The differences in ACS and PCS regarding baseline characteristics, post-operative intracranial hemorr...
CONCLUSION: Unenhanced CT is a mainstay of acute phase imaging due to its availability and, sensitivity and specificity for detecting acute haemorrhage. Several imaging features can be identified on CT and, along with clinical information, can provide some certainty in diagnosis. For those suitable and where diagnostic uncertainty remains CT angiogram, time-resolved CT angiography and catheter angiography can help identify underlying AVMs, aneurysms, cavernomas and vasculitides. MRI is more sensitive for the detection of subacute and chronic haemorrhage and identification of underlying mass lesions. PMID: 32008532 [PubMed - in process]
iak S Abstract Stroke, increasingly recognised in children in recent years, is an important cause of long-term morbidity and disability. It can be classified by the stroke type as either arterial ischaemic stroke (AIS), haemorrhagic stroke (HS), or cerebral sinovenous thrombosis (CSVT). Furthermore, perinatal and childhood stroke can be distinguished. A wide range of conditions associated with paediatric stroke has been identified, which differ significantly from those in adults. A paediatric stroke can also present with a variety of symptoms and signs, both specific and non-specific. Because of the diversity of t...
CONCLUSIONS: Low EPA/AA ratio at baseline and treatment without statins could predict mortality, recurrent ischemic stroke, cardiovascular and peripheral artery diseases, and hemorrhagic stroke among patients with acute ischemic stroke. The combination of baseline EPA/AA ratio and statin therapy could be critical in predicting the long-term prognosis of ischemic stroke patients. PMID: 31969533 [PubMed - as supplied by publisher]
