Our analysis indicated a potential contribution of the localized atherosclerotic process to END in SSSIs. Precautionary measures might be used for SSSIs suggestive of atherosclerotic pathologies.

Even 1 to 2 times a week of MVPA might be beneficial to prevent a first-ever stroke in the general population, although a quantitative validation of the questionnaire is needed. From a public health perspective, we need to encourage inactive people to start exercising with more-achievable goals.

Background and Purpose- Despite early aneurysm repair and aggressive management for complications, subarachnoid hemorrhage (SAH) results in at least 25% mortality rate and 50% persistent neurological deficit. We investigated whether ceria nanoparticles which have potent antioxidative activities can protect against subarachnoid hemorrhage via attenuating fatal brain injuries. Methods- Uniform, 3 nm, water-dispersed ceria nanoparticles were prepared from short sol-gel reaction of cerium (III) ions

In our retrospective analysis of a prospective registry, early antithrombotic (within 24 hours after initiation) administration did not increase hemorrhages after recanalization treatment. Early antithrombotic therapy may be advantageous for a subset of stroke patients despite the current guidelines.

Systemic inflammatory response syndrome (SIRS) is self-destructive and uncontrollable inflammatory response of the whole body triggered by infection, trauma, or a variety of severe injuries. Although reactive oxygen species play a pivotal role in the development of SIRS, the trials with conventional antioxidants have failed to improve patient outcome. Ceria nanoparticles (CeNPs) have potent, autocatalytic reactive oxygen species scavenging activities, which may have sufficient therapeutic effect

Background and Purpose- For patients with emergent large vessel occlusion who may not benefit from timely recanalization treatment, maintaining adequate cerebral perfusion to prevent penumbral tissue loss is a key therapeutic strategy. Cerebral perfusion should be proportional to systemic blood pressure (BP) due to the loss of autoregulation properties in ischemic brain tissue. We hypothesized that acute fluctuations in BP would lead to aggravated penumbral tissue loss in persistent large vessel

To develop deep learning models for predicting Interoperative hypotension (IOH) using waveforms from arterial blood pressure (ABP), electrocardiogram (ECG), and electroencephalogram (EEG), and to determine whether combination ABP with EEG or CG improves model performance. Data were retrieved from VitalDB, a public data repository of vital signs taken during surgeries in 10 operating rooms at Seoul National University Hospital from January 6, 2005, to March 1, 2014. Retrospective data from 14,140

Intracerebral hemorrhage with lower mean HU of hematoma at presentation is more likely to undergo hematoma expansion. This finding suggests the potential presence of clot contraction process that reinforces hemostasis in intracerebral hemorrhage.

Incorporation of post-EVT NIHSS score conferred better discrimination power to the statistical models for functional recovery. Post-EVT NIHSS score may be an appropriate baseline factor when evaluating an intervention after hyperacute period.

Patients with increased tachycardia burden during stroke unit stay have poor functional outcome. Countermeasures against worsening factors might be utilized for patients with increased tachycardia burden.

We propose a weighted ensemble model for ICH detection, trained on large-scale, strongly annotated CT scans, as no model can capture all aspects of complex tasks.

We report a rapidly deteriorating coronavirus disease 2019 (COVID-19) patient, a-58-year-old woman, with severe acute respiratory distress syndrome and shock with hyperpyrexia up to 41.8°C, probably due to the cytokine storm syndrome. Considering extracorporeal membrane oxygenation (ECMO) as the last resort, we applied therapeutic temperature modulation for management of hyperpyrexia. The patient demonstrated rapid improvement in oxygenation and shock after achieving normothermia, and fully reco
