Intraoperative Transcranial Motor-evoked Potential Stimulation Does Not Seem to Cause Seizures.
Intraoperative neurophysiological monitoring is of critical importance in evaluating the functional integrity of the central nervous system during surgery of the central or peripheral nervous system. In a large recent study, transcranial motor-evoked potentials (TcMEPs) were found to be associated with a 0.7% risk of inducing a seizure as diagnosed by clinical observation and electromyography in patients having general anesthesia with intravenous anesthetics. The gold standard for seizure diagnosis, however, is electroencephalography (EEG). The aim of this single-institution retrospective study is to ascertain the risk of intraoperative seizures detected using EEG during surgeries in adult patients undergoing intraoperative monitoring with TcMEPs. ⋯ The intraoperative use of TcMEPs does not seem to cause seizures.

Plaque Characteristics on CT Angiography Do Not Improve the Ability to Predict Hemodynamic Instability During and After Carotid Angioplasty and Stenting.
Hemodynamic instability is commonly seen during carotid angioplasty and stenting. Although prophylactic treatment with anticholinergics is beneficial, selected use in high-risk patients is desirable. This study examines whether plaque characteristics on computed tomography angiography in addition to demographic factors improve predictive capability. ⋯ Individuals without a previous contralateral endarterectomy and/or history of diabetes are at lower risk of hemodynamic instability. The addition of computed tomography angiographic variables does not improve this prediction. Future prospective, randomized work is required to improve our ability to identify and treat individuals at high risk of instability during carotid angioplasty and stenting.

Extracellular Glutamate Concentration Increases Linearly in Proportion to Decreases in Residual Cerebral Blood Flow After the Loss of Membrane Potential in a Rat Model of Ischemia.
Brain ischemia due to disruption of cerebral blood flow (CBF) results in increases in extracellular glutamate concentration and neuronal cell damage. However, the impact of CBF on glutamate dynamics after the loss of the membrane potential remains unknown. ⋯ Our results indicate that residual CBF is an important factor that determines the extracellular glutamate concentration after the loss of membrane potential, and residual CBF would be one of the important determinants of neuronal cell prognosis.

ReviewWomen Representation as First and Corresponding Authors in Neuroanesthesiology and Neurocritical Care Journals: A Retrospective Analysis.
There is limited literature on the representation of women in leading roles in neuroanesthesiology and neurocritical care academia. We aimed to determine the representation of women as first and corresponding authors in articles published in 3 dedicated journals of neuroanesthesiology and neurocritical care during last 5 years. ⋯ Women were underrepresented compared with men as first author of articles published in 3 dedicated neuroanesthesiology and neurocritical care journals over the last 5 years. Women had the lowest representation as authors of Original Research Articles.
