Early High-dosage Atorvastatin Treatment Improved Serum Immune-inflammatory Markers and Functional Outcome in Acute Ischemic Strokes Classified as Large Artery Atherosclerotic Stroke: A Randomized Trial
Abstract: Statins have beneficial effects on cerebral circulation and brain parenchyma during ischemic stroke and reperfusion. The primary hypothesis of this randomized parallel trial was that treatment with 80 mg/day of atorvastatin administered early at admission after acute atherosclerotic ischemic stroke could reduce serum levels of markers of immune-inflammatory activation of the acute phase and that this immune-inflammatory modulation could have a possible effect on prognosis of ischemic stroke evaluated by some outcome indicators. We enrolled 42 patients with acute ischemic stroke classified as large arteries ath...

Evolution of Blood-Brain Barrier Permeability in Subacute Ischemic Stroke and Associations With Serum Biomarkers and Functional Outcome
Conclusion: In patients with moderate-to-severe subacute stroke, three out of four patients demonstrated increased BBB permeability, which decreased over time. The presence of increased BBBP was associated with larger lesion volumes and more severe strokes. We could not detect an association between selected serum biomarkers of inflammation and an increased BBBP in this cohort. No clear association with favorable functional outcome was observed.Trial registration: NCT01954797.

Upregulating microRNA-874-3p inhibits CXCL12 expression to promote angiogenesis and suppress inflammatory response in ischemic stroke.
Abstract Identification of specific biomarkers for ischemic stroke is necessary due to their abilities to improve treatment outcomes. Many studies have demonstrated the involvement of microRNAs (miRNAs) in the pathogenesis and complications of ischemic stroke and patient outcomes. We found that the expression of miR-874-3p was downregulated in clinical samples of ischemic stroke. Thus, the present study explored the potential role of miR-874-3p in ischemic stroke and related mechanisms. A mouse model of ischemic stroke was constructed by middle cerebral artery occlusion. The relationship among miR-874-3p, C-X-C mo...

Duarte, Ivana B.M. da Cruz, Rafael Noal Moresco, Luiz Fernando Freire Royes, Michele Rechia Fighera Oxidative stress and brain inflammation are thought to contribute to the pathophysiology of cerebral injury in acute stroke, leading to apoptosis and cell death. Lipid accumulation may lead to progression of carotid plaques and inflammation, contributing to incre...

Risk of stroke in patients with newly diagnosed multiple myeloma: a retrospective cohort study
This study includes consecutive patients 20 years and older who were newly diagnosed with symptomatic multiple myeloma at Taipei Veterans General Hospital, a tertiary medical center, between January 1, 2002 and December 31, 2014. The primary outcome was stroke development. Patients with head injuries, brain tumors, brain parenchymal invasions, or antecedent malignancies were excluded. Hazard ratios (HRs) of stroke risk factors for multiple myeloma patients were estimated by Cox proportional regression analysis. Overall, 395 patients with a median age of 70 years were investigated. In the median follow‐up period of 18 ...

Regulation of Therapeutic Hypothermia on Inflammatory Cytokines, Microglia Polarization, Migration and Functional Recovery after Ischemic Stroke in Mice.
This study reveals the first evidence for hypothermia mediated regulation on inflammatory factor expression, microglia polarization, migration and indicates that the anti-inflammatory effect is an important mechanism underlying the brain protective effects of a TH therapy.

Inhibition of transient receptor potential vanilloid ‐1 confers neuroprotection, reduces tumor necrosis factor‐alpha, and increases IL‐10 in a rat stroke model
In this study, the effects of TRPV1 agonist (capsaicin) and antagonist (AMG9810) on cerebral ischemia were investigated. Forty male Wistar rats were assigned to the following experimental groups: sham, vehicle) ischemic), AMG9810 (selective TRPV1 antagonist, 0.5 mg/kg; 3 h after stroke), and capsaicin (1 mg/kg; 3 h after stroke). Stroke was induced by permanent middle cerebral artery occlusion and neurological deficits were evaluated 1, 3, and 7 days after stroke. Then, infarct volume, brain edema, body temperature, mRNA expression of TRPV1, and serum concentrations of tumor necrosis factor‐alpha (TNF‐α) and IL‐10 w...

Rates and Predictors of 1 year of Readmission with Seizures in Patients with Stroke and Stroke Subtypes: Analysis of a National Cohort of 557,033 Stroke Patients (P2.245)
Conclusions:Rate readmission of seizure after stroke within first year is low and there may be residual confounding by severity. Our findings do not support a need for routine prophylactic anti-epileptic drug use after stroke.Disclosure: Dr. Chaudhry has nothing to disclose. Dr. Chaudhry has nothing to disclose.

Stroke Mimics in the Acute Setting: Role of Multimodal CT Protocol ADULT BRAIN
CONCLUSIONS: Multimodal CT demonstrated low sensitivity but high specificity in the diagnosis of stroke mimics in the acute setting. The high specificity of multimodal CT allows ruling out stroke and thereby avoiding unnecessary revascularization treatment in patients with diagnosis of a stroke mimic.

Artificial Hibernation by Phenothiazines: A Potential Neuroprotective Therapy Against Cerebral Inflammation in Stroke.
CONCLUSION: This study showed an inhibitory effect of C+P on brain inflammation, which may be partially dependent on drug-induced hibernation, as well as other mechanisms of action by these drugs. These findings further suggest the great potential of C+P in the clinical treatment of ischemic stroke. PMID: 31232236 [PubMed - as supplied by publisher]

Cerebellar Fastigial Nucleus Stimulation in a Chronic Unpredictable Mild Stress Rat Model Reduces Post-Stroke Depression by Suppressing Brain Inflammation via the microRNA-29c/TNFRSF1A Signaling Pathway.
CONCLUSIONS In a rat model, cerebellar fastigial nucleus stimulation reduced the expression of TNFRSF1A by upregulating miR-29c expression, which suppressed the expression of inflammatory cytokines, resulting in reduced severity of post-stroke depression. PMID: 31352465 [PubMed - in process]
