Association of hyperglycemia and computed tomographic perfusion deficits in patients who underwent endovascular treatment for acute ischemic stroke caused by a proximal intracranial occlusion: A subgroup analysis of a randomized phase 3 trial (MR CLEAN)
Hyperglycemia is highly prevalent in patients with acute ischemic stroke and is associated with increased risk of symptomatic intracranial hemorrhage, larger infarct size and unfavorable outcome. Furthermore, glucose may modify the effect of endovascular treatment (EVT) in patients with ischemic stroke. Hyperglycemia might lead to accelerated conversion of penumbra into infarct core. However, it remains uncertain whether hyperglycemia on admission is associated with the size of penumbra or infarct core in acute ischemic stroke.

Time to Endovascular Reperfusion and Outcome in Acute Ischemic Stroke
ConclusionAmong patients with acute ischemic stroke in routine clinical practice, shorter time to reperfusion was associated with better outcome after endovascular therapy. Standardized workflows and training in endovascular treatment techniques should be promoted nationally to reduce in-hospital delays.

Venovenous extracorporeal membrane oxygenation for coronavirus disease 2019 patients: A systematic review and meta-analysis
CONCLUSION: Although COVID-19 patients may have a higher risk of bleeding, hemorrhagic stroke, and acute kidney injury during ECMO therapy, the survival rate was more than half of the cases. Our data may support the application of VV-ECMO in COVID-19 patients.PMID:35608047 | DOI:10.1177/02676591221104302

Paradoxical venous air embolism detected with point-of-care ultrasound: a case report
We present a case of a critical care patient who presented sudden clinical hemodynamic deterioration after the removal of central venous catheter. Hemodynamic evaluation with point-of-care ultrasound (POCUS) showed bubbles in both right and left heart cavities wherewith air embolism facilitated by heart septal defect was suspected. Therefore, the patient was reintubated, supported with vasopressors and a new CVC was inserted to proceed with air aspiration. Shortly after, the patient ’s hemodynamic status improved in terms of vital signs stabilization. 6 h after the event with optimal perfusion markers and diminished sed...

Regulation of Ncbe in the Choroid Plexus of Mice after Hemorrhage-Induced Hydrocephalus
FASEB J. 2022 May;36 Suppl 1. doi: 10.1096/fasebj.2022.36.S1.R3405.ABSTRACTThe choroid plexus (CP) is a small tissue located inside brain ventricles. It is responsible for the production of most of the cerebrospinal fluid (CSF); approximately 500 mL of CSF per day in the adult human [1, 2]. CSF production occurs as a net result of transcellular movement of salt and water, carried out by various cellular transporters. Ncbe is a sodium-coupled bicarbonate transporter located in the basolateral membrane of the choroid plexus epithelial (CPE) cells. It transports Na+ and HCO3 - into the cell in exchange for Cl- . Ncbe is the m...

CT Perfusion Maps Improve Detection of M2-MCA Occlusions in Acute Ischemic Stroke
A growing body of literature supports mechanical thrombectomy-based endovascular therapy for M2-MCA occlusions in eligible patients with acute ischemic stroke (AIS).1 –5 This is because endovascular treatment for M2-MCA occlusions is technically feasible and leads to improved patient outcomes, despite a potential increased risk of hemorrhage.4,5 Not uncommonly, these patients undergo a single or multi-phase CT angiogram (CTA) study for LVO detection. In patient s who present in the late stroke window (6–24 h since last known normal), the CT Perfusion (CTP) study is generally performed along with a CTA study to aid in patient triage.

Impact of Cerebral Autoregulation Monitoring in Cerebrovascular Disease: A Systematic Review
AbstractCerebral autoregulation (CA) prevents brain injury by maintaining a relatively constant cerebral blood flow despite fluctuations in cerebral perfusion pressure. This process is disrupted consequent to various neurologic pathologic processes, which may result in worsening neurologic outcomes. Herein, we aim to highlight evidence describing CA changes and the impact of CA monitoring in patients with cerebrovascular disease, including ischemic stroke, intracerebral hemorrhage (ICH), and aneurysmal subarachnoid hemorrhage (aSAH). The study was preformed according to the Preferred Reporting Items for Systematic Reviews ...
