Combining Human Umbilical Cord Blood Cells With Erythropoietin Enhances Angiogenesis/Neurogenesis and Behavioral Recovery After Stroke
In conclusion, our results suggest that hUCBC infusion in combination with EPO administration demonstrates therapeutic efficacy in the treatment of stroke-induced injury by promoting neurogenesis and angiogenesis. Further research that delineates the therapeutic mechanism of systemically administered hUCBC and EPO is required. Ethics Statement All experimental procedures involving animals were performed in accordance with the Guide for the Care and Use of Laboratory Animals as adopted and promulgated by the U. S. National Institutes of Health and were approved by CHA University Institutional Animal Care & Use Com...

P-016 Relationship between stroke recurrence, infarct pattern, and vascular distribution in patients with symptomatic intracranial stenosis
Conclusion We determined that basilar artery stenosis was most likely to present as a perforator stroke. As expected, patients discharged with suboptimal medical therapy were twice as likely to have a recurrent stroke (29% versus 13%). Among patients with optimal medical therapy, no recurrent strokes were seen in patients with embolic infarct pattern, while 57% recurrence rate was seen in patients with a watershed infarct pattern, suggesting that an embolic infarct pattern on initial presentation is possibly related to underlying plaque instability that is modifiable with optimal medical therapy. On the other hand, initial...

Characteristics of cerebral ischemic stroke based on moyamoya disease and atherosclerosis-associated intracranial arterial stenosis
ConclusionsDiffering from LAS stroke, MMD stroke mainly presents with WSI and does not feature with platelet hyper-aggregation and fragmentation of ulcer plaque. Whereby, focusing on perfusion improvement rather than antiplatelets and statins may be the predominant step in MMD-stroke correction.

Cerebral blood flow evaluation of intensive rosuvastatin therapy in stroke/transient ischemic attack patients with intracranial arterial atherosclerotic stenosis study: Rationale  and design
ConclusionThe CEIRIS trial about the effects of statin on the temporal hemodynamic progression of ICAS may extend our understanding of the basic pathophysiology and mechanisms of stroke in ICAS patients. With the use of computed tomography perfusion, we aim to evaluate the impact of Rosuvastatin on cerebral hemodynamic changes, as well as the downstream perfusion. This trial concerning the effects of statin on the temporal hemodynamic progression of intracranial atherosclerotic stenosis (ICAS) may extend our understanding of the basic pathophysiology and mechanisms of stroke in ICAS patients.

Stenosis Length and Degree Interact With the Risk of Cerebrovascular Events Related to Internal Carotid Artery Stenosis
Conclusion: We found a statistically insignificant tendency for the ultrasound-measured length of sICAS<70% to be longer than that of sICAS≥70%. Moreover, the ultrasound-measured length of sICAS<90% was significantly longer than that of sICAS 90%. Among patients with sICAS≥70%, the degree and length of stenosis were inversely correlated. Larger studies are needed before a clinical implication can be drawn from these results. Introduction Internal carotid artery stenosis (ICAS) causes around one-fifth of ischemic cerebrovascular stroke and has the highest risk of early stroke recurrence...

A Case of Transient Global Amnesia: A Review and How It May Shed Further Insight into the Neurobiology of Delusions
Conclusion In closing, our patient’s episode of TGA combined with her emotional and perceptual response lends credence to the proposal of a “fear/paranoia” circuit in the genesis of paranoid delusions—a circuit incorporating amygdala, frontal, and parietal cortices. Here, neutral or irrelevant stimuli, thoughts, and percepts come to engender fear and anxiety, while dysfunction in frontoparietal circuitry engenders inappropriate social predictions and maladaptive inferences about the intentions of others.[54] Hippocampus relays information about contextual information based on past experiences and the current situat...

Neuroprotective effects and dynamic expressions of MMP9 and TIMP1 associated with atorvastatin pretreatment in ischemia–reperfusion rats
In conclusion, Oral administration of atorvastatin before stroke may reduce the severity in I/R injury and improve neurological outcome by lowering MMP9 levels and elevating TIMP1 levels.

Fool Me Once: An Uncommon Presentation of PE
​BY FREDDIE IRIZARRY-DELGADO; VAROON KAKAIYA; & AHMED RAZIUDDIN, MDAn 86-year-old African-American woman was brought to the ED by her daughter after two days of nutritional neglect, abdominal pain, and altered mental status. Her daughter said her mother felt lightheaded, appeared dehydrated, and vomited nonbilious watery fluid once. The patient had a history of diabetes mellitus type 2, DVT/PE, dementia, and early signs of parkinsonism.Her vital signs were remarkable only for tachypnea (24 bpm). Her troponin I was markedly elevated at 1.7 ng/mL. A D-dimer was ordered because of her history of unprovoked DVT/PE, and i...

Effect of high dose statin preloading on TIMI flow in patients presenting with ST-Elevation Myocardial Infarction undergoing Primary Percutaneous Coronary Intervention
ConclusionHigh intensity statin loading before primary PCI resulted in improved post-procedural TIMI flow, MBG, complete ST-segment resolution and ejection fraction as measured by M-mode but did not decrease incidence of in-hospital MACE.
