Medical professionals can oftentimes fall under the category of "second victims", as they experience burnout and moral injury from the impacts of their work. Over the course of a neurointerventionalist's medical career, serious complications in procedures are sadly inevitable. These can be difficult to process, and there are not always the systems in place to provide the support needed, either inside or outside of the hospital. A new survey has been carried out to assess the severity and prevalence of negative psychological effects on physicians who have experienced these complications. Dr. Ansaar Rai¹ joins JNIS Editor-in-Chief Dr. Michael Chen to discuss the original research piece, "Unseen wounds: a multinational investigation of neurointerventionalists on the psychological toll of complications".

High risk factors for stroke such as smoking and blood pressure are not equally represented throughout the patient population. These are just two of the socioeconomic influences on cerebrovascular disease. One way to view this association is through the lens of the Area Deprivation Index (ADI), a measure of neighbourhood-level deprivation, and this was the approach of the study discussed in this episode. The study evaluated the association between the ADI and the treatment of ruptured intracranial aneurysms compared with unruptured intracranial aneurysms across multiple centres. Editor-in-Chief of JNIS, Dr. Felipe C. Albuquerque, interviews Dr. Alexandra Paul¹, author of the paper: Multicenter study of association between socioeconomic status and treatment of ruptured cerebral aneurysms compared to unruptured cerebral aneurysms: insights from 4,517 patients using the area deprivation index

Patients with good motor function outcomes after aneurysmal subarachnoid hemorrhage treatment may still be left with neuropsychiatric effects. They can suffer from such difficult conditions as cognitive dysfunction, depression and sexual dysfunction. Not all of these patients will volunteer their symptoms unprompted on follow-up. This outcome type has had limited study, and became an interest of today's guest, Dr. Jose Danilo Bengzon Diestro (1). JNIS editor-in-chief Dr. Felipe Albuquerque speaks with him on this subject, based on the recently published paper, "Long-term neuropsychiatric complications of aneurysmal subarachnoid hemorrhage: a narrative review".

The 2013 ARUBA trial concluded that medical management alone is superior to medical management with interventional therapy for patients with unruptured brain arteriovenous malformations. A study was conducted to analyze AVM treatment and epidemiologic response to the ARUBA trial. Following ARUBA, there has been a stark decrease in interventions for uAVMs. Nationwide rAVM discharge incidence is inversely correlated with uAVM intervention rate. Less uAVM interventions may lead to a substantial increase in AVM rupture incidence. In this podcast, JNIS Editor-in-Chief, Dr. Felipe C. Albuquerque speaks with Dr. Evan Luther(1) and Dr. Robert Starke(2) about their paper "Unruptured arteriovenous malformation intervention rate is inversely correlated with ruptured AVM discharge incidence" - https://jnis.bmj.com/content/12/suppl_1/a163.

Survival for glioblastoma remains very poor despite decades of research, with a 5-year survival of only 5%. Technological improvements that have revolutionized treatment of ischemic stroke and brain aneurysms have great potential in providing more precise and selective delivery of cancer therapeutic agents to brain tumors. In this podcast, JNIS Editor-in-Chief, Dr. Felipe C. Albuquerque speaks with Dr. Stephen Chen (1)and Dr. Peter Kan (2) about their paper "Perfusion-guided endovascular super-selective intra-arterial infusion for treatment of malignant brain tumors". The paper describes a technique using perfusion guidance to enhance the precision of endovascular super-selective intra-arterial (ESIA) infusions of mesenchymal stem cells loaded with Delta-24 in the treatment of glioblastoma. This technique enhances targeted super-selective delivery of therapeutic agents for brain tumors. Paper available online (https://jnis.bmj.com/content/14/6/533) and in June print issue of JNIS.

Sex disparities in acute ischemic stroke outcomes are well reported with IV thrombolysis. Despite several studies, there is still a lack of consensus on whether endovascular thrombectomy (EVT) outcomes differ between men and women. In this podcast, we discuss the Selection for Endovascular Treatment in Acute Ischemic Stroke (SELECT) study, in which women had similar discharge outcomes as men following EVT, in a propensity-matched cohort, but the improvement from discharge to 90 days was significantly worse in women, suggesting the influence of post-discharge factors. JNIS Editor-in-Chief, Dr. Felipe C. Albuquerque, interviews Johanna Fifi (Department of Neurosurgery, Icahn School of Medicine at Mount Sinai, New York) and Amrou Sarraj (Department of Neurology, Case Western Reserve University School of Medicine, Cleveland, Ohio).

JNIS Associate Editor Joshua Hirsch is joined by Shazam Hussain (Cerebrovascular Center, Cleveland Clinic, Ohio, USA) and David Fiorella (Department of Neurosurgery, Stony Brook University, New York, USA) to discuss the June 2017's editorial in the Journal of Neurointerventional Surgery.
In this commentary, they analyse the conclusions of the study “Public Health Urgency Created by the Success of Mechanical Thrombectomy Studies in Stroke”, published by Circulation, stating that the opinions of Drs Hopkins and Holmes “lead to unwarranted conclusions that have dangerous implications for patient care”.
The authors of the JNIS editorial comment on three major points of controversy: (1) a disregard for training, expertise, and experience in the management of a disease that may lead to death or disability when treating physicians do not have them; (2) a misunderstanding of the fundamental underpinnings of stroke physiology and anatomy; (3) a false association between a real problem (undeveloped systems of care) and a spurious assumption (ie, that there are not enough physicians trained to perform intracranial MT). We examine these concerns below.
The editorial “In defense of our patients” was written on behalf of the Society of NeuroInterventional Surgery, the Cerebrovascular Section of the American Association of Neurological Surgeons and the Congress of Neurological Surgeons, and the Society of Vascular and Interventional Neurology.

In this podcast, Andrew Kofke, from the Departments of Anesthesiology and Critical Care and Neurosurgery, Perelman School of Medicine, University of Pennsylvania, Philadelphia, USA, reveals the details of his JNIS Editor's Choice paper published in the November 2016 issue.
The study concludes that anesthetic techniques and associated physiology used in endovascular management of acute ischemic stroke (EMAIS) are not homogeneous, making any statements about the effects of generic general anesthesia in stroke ambiguous. In "Anesthetic variation and potential impact of anesthetics used during endovascular management of acute ischemic stroke" the authors also conclude that the type of general anesthesia may affect the outcome after EMAIS.

In this podcast, the Editor-in-Chief of JNIS, Robert Tarr, is joined by Ali Alaraj, the corresponding author of the study, "Increased prevalence and rupture status of feeder vessel aneurysms in posterior fossa arteriovenous malformations".
Dr Alaraj, from the Department of Neurosurgery, Neuropsychiatric Institute University of Illinois, Chicago, USA, explains why are posterior cranial fossa arteriovenous malformations (AVMs) more prone to developing associated aneurysms, specifically feeder vessel aneurysms. Feeder vessel aneurysms are more likely to be the source of hemorrhage in the posterior fossa. As such, they may be the most appropriate targets for initial and prompt control by embolization or surgery due to their elevated threat.

In this podcast, Dr Robert Tarr interviews Dr Matthew Gounis and Dr Ajit Puri on their latest study, "Grading of Regional Apposition after Flow-Diverter Treatment (GRAFT): a comparative evaluation of VasoCT and intravascular OCT".
GRAFT is a semi-automated image post-processing software, which uses intuitive two-dimensional representations of wall apposition from either high-resolution contrast-enhanced cone-beam CT (VasoCT) or intravascular optical coherence tomography (OCT) images. The technique brings great prospects of reducing stroke-related complications when treating intracranial aneurysms. It delivers quantitative and visually convenient representations of potential flow diverter malapposition and occasional acute thrombus formation.

On Dec 17th 2014, the NEJM published the results of MR CLEAN; a Dutch study comparing patients treated with intra-arterial thrombolysis to those of a medically managed cohort. The design of this trial was ingenious; focusing attention on patients who appeared to have failed intravenous thrombolysis. The IAT managed group performed quite favorably with respect to this control group.
Three associate editors, Drs. Hirsch, Fiorella and Mocco discuss the impact of MR CLEAN and their personal loss of equipoise in this cohort of patients.

Pretreatment Alberta Stroke Program Early CT Scores (ASPECTS) is associated with clinical outcomes. The rate of decline between subsequent images, however, may be more predictive of outcomes as it integrates time and physiology.
A paper published in the January issue of JNIS retrospectively looked at patients transferred from six primary stroke centers and treated with intra-arterial therapy (IAT). They found patients with faster rates of ASPECTS decay during inter-facility transfers are associated with worse clinical outcomes.
Rob Tarr discusses the work with co-author Rishi Gupta, Wellstar Neurosurgery, Marietta, USA.

The Patient Protection and Affordable Care Act (ACA) became law on 23 March 2010. As part of the law, two independent boards were established. The Patient-Centered Outcomes Research Institute embodies national aspirations for employing comparative effectiveness research in healthcare decision-making, and the Independent Payment Advisory Board is focused on the need for a group of impartial experts to establish anticipatable growth rates for Medicare.
Approximately 4 years after the bill was passed into law, these independent boards are at very different points in their life cycles.
In this podcast, Josh Hirsch, Neuroendovascular Program, Massachusetts General Hospital, Harvard Medical School, Geraldine McGinty, Department of Radiology, Weill Cornell Medical College, New York, and Richard Duszak, Vice Chair for Health Policy and Practice, Department of Radiology and Imaging Sciences, Emory University School of Medicine, give us a status update.
