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.

The Woven EndoBridge (WEB) device has FDA approval for treatment of wide-necked intracranial bifurcation aneurysms. It has been shown to result in adequate occlusion in bifurcation aneurysms overall, but its usefulness in the individual bifurcation locations has been evaluated separately only in few case series, which were limited by small sample sizes. In this podcast, JNIS Editor-in-Chief, Dr. Felipe C. Albuquerque, interviews Dr. Nimer Adeeb (1)and Dr. Adam Dmytriw (2) on their paper "Comparing treatment outcomes of various intracranial bifurcation aneurysms locations using the Woven EndoBridge (WEB) device".

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).

Venous sinus stenting (VSS) is a safe, effective, and increasingly popular treatment option for selected patients with idiopathic intracranial hypertension (IIH). Serious complications associated with VSS are rarely reported.

In this podcast, JNIS Editor-in-Chief, Felipe C. Albuquerque, interviews Dr. Kyle Fargen, from the Department of Neurosurgery, Wake Forest University, Winston-Salem, North Carolina, about a case series in which serious complications after VSS were identified retrospectively from multicenter databases. The cases are reviewed and learning points regarding complication avoidance and management are presented in his paper (https://jnis.bmj.com/content/early/2021/04/27/neurintsurg-2021-017361).

In this podcast, we discuss the COMPASS: a trial of aspiration thrombectomy versus stent retriever thrombectomy as first-line approach for large vessel occlusion, comparing patients with and without prior intravenous (IV) alteplase administration. JNIS Editor-in-Chief, Felipe C. Albuquerque, interviews Maxim Mokin, from the Department of Neurosurgery and Brain Repair, University of South Florida, Tampa, USA, about the post hoc analysis. which concludes that prior administration of IV alteplase may adversely affect the efficacy of aspiration, whilst it does not seem to influence the stent retriever first approach to MT in patients with anterior circulation ELVO.

Sexism is common place in one of the most male-dominated subspecialties in medicine. Despite this, the prevalence of women physicians in neurointervention is steadily rising. In this podcast, JNIS Editor-In-Chief, Felipe C. Albuquerque, interviews neurointerventionalists Stephanie H Chen - Department of Neurological Surgery, University of Miami School of Medicine - and Marie-Christine Brunet - Department of Neurological Surgery (NEUR) at McGill University - about the challenges of being a female physician in this field. They are the authors of the first study examining the amount of maternal and fetal radiation exposure during a pregnant neurointerventional fellow’s training. Spoiler alert: the findings suggest that, when optimal radiation safety practices are implemented, the fetal dose of a pregnant neurointerventionalist is negligible.
