Preparing Neurology Residents and Advanced Practice Providers for the COVID-19 ICU-A Neurocritical Care Led Intervention.

Background And Purpose: With the surge of critically ill COVID-19 patients, neurology and neurosurgery residents and advanced practice providers (APPs) were deployed to intensive care units (ICU). These providers lacked relevant critical care training. We investigated whether a focused video-based learning curriculum could effectively teach high priority intensive care topics in this unprecedented setting to these neurology providers.

Suspected Lower Extremity Ischemia After End-to-Side Femoral Arterial Grafting for VA-ECMO.

Lower extremity ischemic complications are frequently encountered after femoral cannulation for venoarterial extracorporeal membrane oxygenation (VA-ECMO). Many are attributed to mechanical obstruction of distal arterial blood flow related to intraluminal positioning of the arterial cannula. Routine use of distal perfusion catheters is ineffective at eliminating the development of these serious complications.

How Cardiac Anesthesiology Can Help "STEM" the Tide of Under-representation of Minorities in Science and Medicine.

The field of medicine is built upon science, technology, engineering, and math (STEM), yet the United States is rapidly falling behind when it comes to educating the next generation in these disciplines, especially under-represented populations. The authors reflect on existing educational literature surrounding efforts to promote interest in STEM among students and under-represented populations. The authors advocate for greater efforts toward the development of youth programing.

Use of Methohexital and Dexmedetomidine for Maintenance of Anesthesia in a Patient With Mitochondrial Myopathy: A Case Report.

Provision of anesthesia for patients with mitochondrial disorders is associated with a unique set of challenges. These disorders are rare, which complicates efforts to develop high quality, evidence-based guidelines to inform the perioperative management of those who suffer from them. Accordingly, case reports remain an important source of information regarding their care.

Propofol at clinically relevant concentrations increases neuronal differentiation but is not toxic to hippocampal neural precursor cells in vitro.

Background: Propofol in the early postnatal period has been shown to cause brain cell death. One proposed mechanism for cognitive dysfunction after anesthesia is alteration of neural stem cell function and neurogenesis. We examined the effect of propofol on neural precursor or stem cells (NPCs) grown in vitro.

Networked T cell death following macrophage infection by Mycobacterium tuberculosis.

Background: Depletion of T cells following infection by Mycobacterium tuberculosis (Mtb) impairs disease resolution, and interferes with clinical test performance that relies on cell-mediated immunity. A number of mechanisms contribute to this T cell suppression, such as activation-induced death and trafficking of T cells out of the peripheral circulation and into the diseased lungs. The extent to which Mtb infection of human macrophages affects T cell viability however, is not well characterised.

Delayed environmental enrichment reverses sevoflurane-induced memory impairment in rats.

Background: Anesthesia given to immature rodents causes cognitive decline, raising the possibility that the same might be true for millions of children undergoing surgical procedures under general anesthesia each year. We tested the hypothesis that anesthesia-induced cognitive decline in rats is treatable. We also tested if anesthesia-induced cognitive decline is aggravated by tissue injury.

Selective deficits in the expression of striatal-enriched mRNAs in Huntington's disease.

We have identified and cataloged 54 genes that exhibit predominant expression in the striatum. Our hypothesis is that such mRNA molecules are likely to encode proteins that are preferentially associated with particular physiological processes intrinsic to striatal neurons, and therefore might contribute to the regional specificity of neurodegeneration observed in striatal disorders such as Huntington's disease (HD). Expression of these genes was measured simultaneously in the striatum of HD R6/1 transgenic mice using Affymetrix oligonucleotide arrays.
