Abstract
Acute stroke is one of the most common neurologic emergencies encountered by emergency clinicians. While point of care ultrasound has been a core part of emergency clinicians' training and practice for many years, the use of specialized ultrasound modalities in the care of acute ischemic stroke has not been as widely adopted. This review discusses the use of ultrasound in acute stroke, with a focus on applications of interest to emergency clinicians. Transcranial Doppler, carotid Doppler, microembolic signal detection, transthoracic echocardiography, evaluation for collateral circulation and optic nerve sheath diameter measurement are discussed in a case-based format, with a focus on practical applications for emergency clinicians.

Abstract
RATIONALE New evidence is available examining the use of corticosteroids in sepsis, acute respiratory distress syndrome (ARDS) and community-acquired pneumonia (CAP), warranting a focused update of the 2017 guideline on critical illness-related corticosteroid insufficiency. OBJECTIVES To develop evidence-based recommendations for use of corticosteroids in hospitalized adults and children with sepsis, ARDS, and CAP. PANEL DESIGN The 22-member panel included diverse representation from medicine, including adult and pediatric intensivists, pulmonologists, endocrinologists, nurses, pharmacists, and clinician-methodologists with expertise in developing evidence-based Clinical Practice Guidelines. We followed Society of Critical Care Medicine conflict of interest policies in all phases of the guideline development, including task force selection and voting. METHODS After development of five focused Population, Intervention, Control, and Outcomes (PICO) questions, we conducted systematic reviews to identify the best available evidence addressing each question. We evaluated the certainty of evidence using the Grading of Recommendations Assessment, Development, and Evaluation approach and formulated recommendations using the evidence-to-decision framework. RESULTS In response to the five PICOs, the panel issued four recommendations addressing the use of corticosteroids in patients with sepsis, ARDS, and CAP. These included a conditional recommendation to administer corticosteroids for patients with septic shock and critically ill patients with ARDS and a strong recommendation for use in hospitalized patients with severe CAP. The panel also recommended against high dose/short duration administration of corticosteroids for septic shock. In response to the final PICO regarding type of corticosteroid molecule in ARDS, the panel was unable to provide specific recommendations addressing corticosteroid molecule, dose, and duration of therapy, based on currently available evidence. CONCLUSIONS The panel provided updated recommendations based on current evidence to inform clinicians, patients, and other stakeholders on the use of corticosteroids for sepsis, ARDS, and CAP.

Abstract
Introduction/Aims Muscle ultrasound has high utility in clinical practice and research; however, the main challenges are the training and time required for manual analysis to achieve objective quantification of morphometry. This study aimed to develop and validate a software tool powered by artificial intelligence (AI) by measuring its consistency and predictability of expert manual analysis quantifying lower limb muscle ultrasound images across healthy, acute, and chronic illness subjects. Methods Quadriceps complex (QC [rectus femoris and vastus intermedius]) and tibialis anterior (TA) muscle ultrasound images of healthy, intensive care unit, and/or lung cancer subjects were captured with portable devices. Automated analyses of muscle morphometry were performed using a custom-built deep-learning model (MyoVision-US), while manual analyses were performed by experts. Consistency between manual and automated analyses was determined using intraclass correlation coefficients (ICC), while predictability of MyoVision -US was calculated using adjusted linear regression (adj.R 2 ). Results Manual analysis took approximately 24 hours to analyze all 180 images, while MyoVision - US took 247 seconds, saving roughly 99.8%. Consistency between the manual and automated analyses by ICC was good to excellent for all QC (ICC:0.85-0.99) and TA (ICC:0.93-0.99) measurements, even for critically ill (ICC:0.91-0.98) and lung cancer (ICC:0.85-0.99) images. The predictability of MyoVision-US was moderate to strong for QC (adj.R 2 :0.56-0.94) and TA parameters (adj.R 2 :0.81-0.97). Discussion The application of AI automating lower limb muscle ultrasound analyses showed excellent consistency and strong predictability compared with human analysis. Future work needs to explore AI-powered models for the evaluation of other skeletal muscle groups.

Abstract
Despite the growing use of point of care ultrasound (POCUS) in contemporary medical practice and the existence of clinical guidelines addressing its specific applications, there remains a lack of standardization and agreement on optimal practices for several areas of POCUS use. The Society of Point of Care Ultrasound (SPOCUS) formed a working group in 2022 to establish a set of recommended best practices for POCUS, applicable to clinicians regardless of their training, specialty, resource setting, or scope of practice. Using a three-round modified Delphi process, a multi-disciplinary panel of 22 POCUS experts based in the United States reached consensus on 57 statements in domains including: (1) The definition and clinical role of POCUS; (2) Training pathways; (3) Credentialing; (4) Cleaning and maintenance of POCUS devices; (5) Consent and education; (6) Security, storage, and sharing of POCUS studies; (7) Uploading, archiving, and reviewing POCUS studies; and (8) Documenting POCUS studies. The consensus statements are provided here. While not intended to establish a standard of care or supersede more targeted guidelines, this document may serve as a useful baseline to guide clinicians, leaders, and systems considering initiation or enhancement of POCUS programs.

Abstract
As the scope of point-of-care ultrasound (POCUS) expands in clinical medicine, its application in neurological applications offers a non-invasive, bedside diagnostic tool. With historical insights, detailed techniques and clinical applications, the chapter provides a comprehensive overview of neurology-based POCUS. It examines the applications, emphasizing its role when traditional neuroimaging is inaccessible or unsafe as well advocating for its use as an adjunctive tool, rather than a replacement of advanced imaging. The chapter covers a range of uses of neuro POCUS including assessment of midline shift, intracranial hemorrhage, hydrocephalus, vasospasm, intracranial pressure, cerebral circulatory arrest, and ultrasound-guided lumbar puncture.

Abstract
BACKGROUND The early management of polytrauma patients with traumatic spinal cord injury (tSCI) is a major challenge. Sparse data is available to provide optimal care in this scenario and worldwide variability in clinical practice has been documented in recent studies. METHODS A multidisciplinary consensus panel of physicians selected for their established clinical and scientific expertise in the acute management of tSCI polytrauma patients with different specializations was established. The World Society of Emergency Surgery (WSES) and the European Association of Neurosurgical Societies (EANS) endorsed the consensus, and a modified Delphi approach was adopted. RESULTS A total of 17 statements were proposed and discussed. A consensus was reached generating 17 recommendations (16 strong and 1 weak). CONCLUSIONS This consensus provides practical recommendations to support a clinician's decision making in the management of tSCI polytrauma patients.

Abstract
Acute brain injuries, such as traumatic brain injury and ischemic and hemorragic stroke, are a leading cause of death and disability worldwide. While characterized by clearly distict primary events-vascular damage in strokes and biomechanical damage in traumatic brain injuries-they share common secondary injury mechanisms influencing long-term outcomes. Growing evidence suggests that a more personalized approach to optimize energy substrate delivery to the injured brain and prognosticate towards families could be beneficial. In this context, continuous invasive and/or non-invasive neuromonitoring, together with clinical evaluation and neuroimaging to support strategies that optimize cerebral blood flow and metabolic delivery, as well as approaches to neuroprognostication are gaining interest. Recently, the European Society of Intensive Care Medicine organized a 2-day course focused on a practical case-based clinical approach of acute brain-injured patients in different scenarios and on future perspectives to advance the management of this population. The aim of this manuscript is to update clinicians dealing with acute brain injured patients in the intensive care unit, describing current knowledge and clinical practice based on the insights presented during this course.

Abstract
The COVID-19 pandemic has evolved since the publication of the initial American Society of Echocardiography (ASE) statements providing guidance to echocardiography laboratories. In light of new developments, the ASE convened a diverse, expert writing group to address the current state of the COVID-19 pandemic and to apply lessons learned to echocardiography laboratory operations in future pandemics. This statement addresses important areas specifically impacted by the current and future pandemics: (1) indications for echocardiography, (2) application of echocardiographic services in a pandemic, (3) infection/transmission mitigation strategies, (4) role of cardiac point-of-care ultrasound/critical care echocardiography, and (5) training in echocardiography.

Abstract
Cerebral autoregulation (CA) is a physiological mechanism that maintains constant cerebral blood flow regardless of changes in cerebral perfusion pressure and prevents brain damage caused by hypoperfusion or hyperperfusion. In recent decades, researchers have investigated the range of systemic blood pressures and clinical management strategies over which cerebral vasculature modifies intracranial hemodynamics to maintain cerebral perfusion. However, proposed clinical interventions to optimize autoregulation status have not demonstrated clear clinical benefit. As future trials are designed, it is crucial to comprehend the underlying cause of our inability to produce robust clinical evidence supporting the concept of CA-targeted management. This article examines the technological advances in monitoring techniques and the accuracy of continuous assessment of autoregulation techniques used in intraoperative and intensive care settings today. It also examines how increasing knowledge of CA from recent clinical trials contributes to a greater understanding of secondary brain injury in many disease processes, despite the fact that the lack of robust evidence influencing outcomes has prevented the translation of CA-guided algorithms into clinical practice.

Abstract
OBJECTIVE This article reviews the neurologic complications encountered in patients admitted to non-neurologic intensive care units, outlines various scenarios in which a neurologic consultation can add to the diagnosis or management of a critically ill patient, and provides advice on the best diagnostic approach in the evaluation of these patients. LATEST DEVELOPMENTS Increasing recognition of neurologic complications and their adverse impact on long-term outcomes has led to increased neurology involvement in non-neurologic intensive care units. The COVID-19 pandemic has highlighted the importance of having a structured clinical approach to neurologic complications of critical illness as well as the critical care management of patients with chronic neurologic disabilities. ESSENTIAL POINTS Critical illness is often accompanied by neurologic complications. Neurologists need to be aware of the unique needs of critically ill patients, especially the nuances of the neurologic examination, challenges in diagnostic testing, and neuropharmacologic aspects of commonly used medications.

Abstract
BACKGROUND AND PURPOSE Ultrasound-derived diagnosis of transverse venous sinus stenosis (TVSS) may have a promise given recent exploration of its role in pathophysiology of intracranial hypertension and availability of interventions like venous stenting. We investigated transverse venous sinus (TVS) insonation using transcranial color-coded duplex (TCCD) to establish normative values, inform on inherent physiological variability, and other measures to allow future studies on testing the construct validity of TCCD venous in diagnosing TVSS. METHODS An institutional review board-approved prospective observational study evaluated 20 healthy volunteers to define TCCD-based measures for the TVS. Comparatively, the basal vein of Rosenthal, deep middle cerebral veins, and internal jugular veins were insonated. We report on physiological variability including the intrasubject, intersubject, and side-to-side variability; gradient of TVS velocities on each side from medial to lateral insonation; and the relationship between TVS and other insonated venous structures. RESULTS Fifteen out of 20 subjects had the TVS insonated bilaterally, and five had unilaterally (four right, one left). TVS velocities had comparable intrasubject variability to other intracranial veins insonated and lower velocity-based variability than the pulsatility index. There was significant side-side variability in TVS-derived measures without discernible patterns. Insonating TVS from medial to lateral revealed a gradient with a bimodal peak in ultrasound-derived velocities. We did not find discernible relationships between TVS and other veins for TCCD-derived measures. CONCLUSIONS These results can inform future studies validating the normative values in a larger sample and help explore the role of TCCD venous in the diagnosis of venous sinus stenosis.

Abstract
OBJECTIVES Critically ill patients are at high risk of acute brain injury. Bedside multimodality neuromonitoring techniques can provide a direct assessment of physiologic interactions between systemic derangements and intracranial processes and offer the potential for early detection of neurologic deterioration before clinically manifest signs occur. Neuromonitoring provides measurable parameters of new or evolving brain injury that can be used as a target for investigating various therapeutic interventions, monitoring treatment responses, and testing clinical paradigms that could reduce secondary brain injury and improve clinical outcomes. Further investigations may also reveal neuromonitoring markers that can assist in neuroprognostication. We provide an up-to-date summary of clinical applications, risks, benefits, and challenges of various invasive and noninvasive neuromonitoring modalities. DATA SOURCES English articles were retrieved using pertinent search terms related to invasive and noninvasive neuromonitoring techniques in PubMed and CINAHL. STUDY SELECTION Original research, review articles, commentaries, and guidelines. DATA EXTRACTION Syntheses of data retrieved from relevant publications are summarized into a narrative review. DATA SYNTHESIS A cascade of cerebral and systemic pathophysiological processes can compound neuronal damage in critically ill patients. Numerous neuromonitoring modalities and their clinical applications have been investigated in critically ill patients that monitor a range of neurologic physiologic processes, including clinical neurologic assessments, electrophysiology tests, cerebral blood flow, substrate delivery, substrate utilization, and cellular metabolism. Most studies in neuromonitoring have focused on traumatic brain injury, with a paucity of data on other clinical types of acute brain injury. We provide a concise summary of the most commonly used invasive and noninvasive neuromonitoring techniques, their associated risks, their bedside clinical application, and the implications of common findings to guide evaluation and management of critically ill patients. CONCLUSIONS Neuromonitoring techniques provide an essential tool to facilitate early detection and treatment of acute brain injury in critical care. Awareness of the nuances of their use and clinical applications can empower the intensive care team with tools to potentially reduce the burden of neurologic morbidity in critically ill patients.

Abstract
BackgroundPatients with severe acute brain injuries (SABI) are at risk of living with long-term disability, frequent medical complications and high rates of mortality. Determining an individual patient’s prognosis and conveying this to family members/caregivers can be challenging. We conducted a webinar with experts in neurosurgery, neurocritical care, neuro-palliative care, neuro-ethics, and rehabilitation as part of the Curing Coma Campaign, which is supported by the Neurocritical Care Society. The webinar discussed topics focused on prognostic uncertainty, communicating prognosis to family members/caregivers, gaps within healthcare systems, and research infrastructure as it relates to patients experiencing SABI. The purpose of this manuscript is to describe the themes that emerged from this virtual discussion.MethodsA qualitative analysis of a webinar “Prognostic Humility and Ethical Dilemmas in Acute Brain Injury” was organized as part of the Neurocritical Care Society’s Curing Coma Campaign. A multidisciplinary group of experts was invited as speakers and moderators of the webinar. The content of the webinar was transcribed verbatim. Two qualitative researchers (NK and BM) read and re-read the transcription, and familiarized themselves with the text. The two coders developed and agreed on a code book, independently coded the transcript, and discussed any discrepancies. The transcript was analyzed using inductive thematic analysis of codes and themes that emerged within the expert discussion.ResultsWe coded 168 qualitative excerpts within the transcript. Two main themes were discussed: (1) the concept of prognostic uncertainty in the acute setting, and (2) lack of access to and evidence for quality rehabilitation and specialized continuum of care efforts specific to coma research. Within these two main themes, we found 5 sub-themes, which were broken down into 23 unique codes. The most frequently described code was the need for clinicians to acknowledge our own uncertainties when we discuss prognosis with families, which was mentioned 13 times during the webinar. Several strategies were described for speaking with surrogates of patients who have had a severe brain injury resulting in SABI. We also identified important gaps in the United States health system and in research to improve the care of patients with severe brain injuries.ConclusionAs a result of this webinar and expert discussion, authors identified and analyzed themes related to prognostic uncertainty with SABI. Recommendations were outlined for clinicians who engage with surrogates of patients with SABI to foster informed decisions for their loved one. Finally, recommendations for changes in healthcare systems and research support are provided in order to continue to propel SABI science forward to improve future prognostic certainty.

Abstract
OBJECTIVE Significant variations exist in the use of respiratory muscle ultrasound in intensive care with no society-level consensus on the optimal methodology. This systematic review aims to evaluate, synthesize, and compare the clinimetric properties of different image acquisition and analysis methodologies. DATA SOURCES Systematic search of five databases up to November 24, 2021. STUDY SELECTION Studies were included if they enrolled at least 50 adult ICU patients, reported respiratory muscle (diaphragm or intercostal) ultrasound measuring either echotexture, muscle thickness, thickening fraction, or excursion, and evaluated at least one clinimetric property. Two independent reviewers assessed titles, abstracts, and full text against eligibility. DATA EXTRACTION Study demographics, ultrasound methodologies, and clinimetric data. DATA SYNTHESIS Sixty studies, including 5,025 patients, were included with 39 studies contributing to meta-analyses. Most commonly measured was diaphragm thickness (DT) or diaphragm thickening fraction (DTF) using a linear transducer in B-mode, or diaphragm excursion (DE) using a curvilinear transducer in M-mode. There are significant variations in imaging methodology and acquisition across all studies. Inter- and intrarater measurement reliabilities were generally excellent, with the highest reliability reported for DT (ICC, 0.98; 95% CI, 0.94-0.99). Pooled data demonstrated acceptable to excellent accuracy for DT, DTF, and DE to predicting weaning outcome after 48 to 72 hours postextubation (DTF AUC, 0.79; 95% CI, 0.73-0.85). DT imaging was responsive to change over time. Only three eligible studies were available for intercostal muscles. Intercostal thickening fraction was shown to have excellent accuracy of predicting weaning outcome after 48-hour postextubation (AUC, 0.84; 95% CI, 0.78-0.91). CONCLUSIONS Diaphragm muscle ultrasound is reliable, valid, and responsive in ICU patients, but significant variation exists in the imaging acquisition and analysis methodologies. Future work should focus on developing standardized protocols for ultrasound imaging and consider further research into the role of intercostal muscle imaging.

Abstract
BACKGROUND AND PURPOSE Transcranial ultrasonography (TCU) can be a useful diagnostic tool in evaluating intracranial pathology in patients with limited or delayed access to routine neuroimaging in critical care or austere settings. We reviewed available literature investigating the diagnostic utility of TCU for detecting pediatric and adult patient's intracranial pathology in patients with intact skulls and reported diagnostic accuracy measures. METHODS We performed a systematic review of PubMed® , Cochrane Library, Embase® , Scopus® , Web of Science™, and Cumulative Index to Nursing and Allied Health Literature databases to identify articles evaluating ultrasound-based detection of intracranial pathology in comparison to routine imaging using broad Medical Subject Heading sets. Two independent reviewers reviewed the retrieved articles for bias using the Quality Assessment of Diagnostic Accuracy Studies tools and extracted measures of diagnostic accuracy and ultrasound parameters. Data were pooled using meta-analysis implementing a random-effects approach to examine the sensitivity, specificity, and accuracy of ultrasound-based diagnosis. RESULTS A total of 44 studies out of the 3432 articles screened met the eligibility criteria, totaling 2426 patients (Mean age: 60.1 ± 14.52 years). We found tumors, intracranial hemorrhage (ICH), and neurodegenerative diseases in the eligible studies. Sensitivity, specificity, and accuracy of TCU and their 95% confidence intervals were 0.80 (0.72, 0.89), 0.71 (0.59, 0.82), and 0.76 (0.71, 0.82) for neurodegenerative diseases; 0.88 (0.74, 1.02), 0.81 (0.50, 1.12), and 0.94 (0.92, 0.96) for ICH; and 0.97 (0.92, 1.03), 0.99 (0.96, 1.01), and 0.99 (0.97, 1.01) for intracranial masses. No studies reported ultrasound presets. CONCLUSIONS TCU has a reasonable sensitivity and specificity for detecting intracranial pathology involving ICH and tumors with clinical applications in remote locations or where standard imaging is unavailable. Future studies should investigate ultrasound parameters to enhance diagnostic accuracy in diagnosing intracranial pathology.

Abstract
BACKGROUND Transcranial Doppler ultrasonography (TCD) is a portable, bedside, noninvasive diagnostic tool used for the real-time assessment of cerebral hemodynamics. Despite the evident utility of TCD and the ability of this technique to function as a stethoscope to the brain, its use has been limited to specialized centers because of the dearth of technical and clinical expertise required to acquire and interpret the cerebrovascular parameters. Additionally, the conventional pragmatic episodic TCD monitoring protocols lack dynamic real-time feedback to guide time-critical clinical interventions. Fortunately, with the recent advent of automated robotic TCD technology in conjunction with the automated software for TCD data processing, we now have the technology to automatically acquire TCD data and obtain clinically relevant information in real-time. By obviating the need for highly trained clinical personnel, this technology shows great promise toward a future of widespread noninvasive monitoring to guide clinical care in patients with acute brain injury. METHODS Here, we describe a proposal for a prospective observational multicenter clinical trial to evaluate the safety and feasibility of prolonged automated robotic TCD monitoring in patients with severe acute traumatic brain injury (TBI). We will enroll patients with severe non-penetrating TBI with concomitant invasive multimodal monitoring including, intracranial pressure, brain tissue oxygenation, and brain temperature monitoring as part of standard of care in centers with varying degrees of TCD availability and experience. Additionally, we propose to evaluate the correlation of pertinent TCD-based cerebral autoregulation indices such as the critical closing pressure, and the pressure reactivity index with the brain tissue oxygenation values obtained invasively. CONCLUSIONS The overarching goal of this study is to establish safety and feasibility of prolonged automated TCD monitoring for patients with TBI in the intensive care unit and identify clinically meaningful and pragmatic noninvasive targets for future interventions.

Abstract
BACKGROUND AND PURPOSE Many studies have explored the possibility of using cranial ultrasound for discerning intracranial pathologies like tumors, hemorrhagic stroke, or subdural hemorrhage in clinical scenarios where computer tomography may not be accessible or feasible. The visualization of intracranial anatomy on B-mode ultrasound is challenging due to the presence of the skull that limits insonation to a few segments on the temporal bone that are thin enough to allow transcranial transmission of sound. Several artifacts are produced by hyperechoic signals inherent in brain and skull anatomy when images are created using temporal windows. METHODS While the literature has investigated the accuracy of diagnosis of intracranial pathology with ultrasound, we lack a reference source for images acquired on cranial topography on B-mode ultrasound to illustrate the appearance of normal and abnormal structures of the brain and skull. Two investigators underwent hands-on training in Cranial point-of-care ultrasound (c-POCUS) and acquired multiple images from each patient to obtain the most in-depth images of brain to investigate all visible anatomical structures and pathology within 24 hours of any CT/MRI imaging done. RESULTS Most reproducible structures visible on c-POCUS included bony parts and parenchymal structures. Transcranial and abdominal presets were equivalent in elucidating anatomical structures. Brain pathology like parenchymal hemorrhage, cerebral edema, and hydrocephalus were also visualized. CONCLUSIONS We present an illustrated anatomical atlas of cranial ultrasound B-mode images acquired in various pathologies in a critical care environment and compare our findings with published literature by performing a scoping review of literature on the subject.

Abstract
OBJECTIVE Given the challenges of patient-provider communication in neurocritical care lacking robust decision-making tools on prognostication, we investigated concordance in perceptions of communication among participants in family discussions and assess the different domains of communication that affect these perceptions. METHODS Prospective observational study conducted over 4 months in a tertiary-level academic medical center neurocritical care unit. Our study involved family discussions regarding plan of care for admitted patients observed by a neutral observer. All participants completed a survey. The first four questions rated the understanding of the discussion and general satisfaction; the remaining questions were open-ended to assess the quality of communication by the physician leading the discussion. Responses were scored and compared among participants using a Likert scale. A difference of < 1 in scores among participants was rated as concordance, whereas that of > 1 was designated as discordance. All open-ended responses were classified into six domains. RESULTS We observed 35 family discussions. Questions 1 to 3 inquiring on general satisfaction, impact, and understanding of treatment options yielded 99 cross-comparisons per question (297 compared responses). Most responses were either "Strongly Agree" or "Agree," with "Neutral" or "Disagree" responses being more prevalent in Question 2 regarding the impact of the conversation. Overall concordance of responses between participants was 88% with a lower rate of concordance (72%) on Q2. Further open-ended questions queried observers on specific physician-spoken content, and answers were analyzed to identify domains that affected the perception of quality of communication. Education was the most frequently cited domain of communication in response to open-ended questions. Among family and neutral observers, empathy was frequently listed, whereas providers more often listed family engagement. CONCLUSION Overall, satisfaction was high among providers, families, and the observer regarding the quality of communication during family discussions in the unit. Perceptual differences emerged over whether this communication impacted healthcare decision-making during that encounter.

Abstract
PURPOSE OF REVIEW This article discusses neurologic complications encountered in the postoperative care of neurosurgical patients that are common or key to recognize in the immediate postoperative period. The major neurosurgical subspecialty procedures (cerebrovascular neurosurgery, neuro-oncology, epilepsy neurosurgery, functional neurosurgery, CSF diversion, endovascular neurosurgery, and spinal surgery) are broadly included under craniotomy procedures, endovascular/vascular procedures, and spinal procedures. This article focuses on the range of complications inherent in these approaches with specific scenarios addressed as applicable. RECENT FINDINGS The morbidity and mortality related to neurosurgical procedures remains high, necessitating ongoing research and quality improvement efforts in perioperative screening, intraoperative management, surgical approaches, and postoperative care of these patients. Emerging research continues to investigate safer and newer options for routine neurosurgical approaches, such as coiling over clipping for amenable aneurysms, endoscopic techniques for transsphenoidal hypophysectomy, and minimally invasive spinal procedures; postoperative monitoring and care of patients after these procedures continues to be a key component in the continuum of care for improving outcomes. SUMMARY Postoperative care of patients undergoing major neurosurgical procedures is an integral part of many neurocritical care practices. Neurosurgeons often enlist help from neurologists to assist with evaluation, interpretation, and management of complications in routine inpatient settings. Awareness of the common neurologic complications of various neurosurgical procedures can help guide appropriate clinical monitoring algorithms and quality improvement processes for timely evaluation and management of these patients.

Abstract
OBJECTIVES Point-of-care ultrasound (PoCUS) has been integrated into undergraduate medical education. The COVID-19 pandemic forced medical schools to evolve clinical rotations to minimize interruption through implementation of novel remote learning courses. To address the students' need for remote clinical education, we created a virtual PoCUS course for our fourth-year class. We present details of the course's development, implementation, quality improvement processes, achievements, and limitations. METHODS A virtual PoCUS course was created for 141 fourth-year medical students. The learning objectives included ultrasound physics, performing and interpreting ultrasound applications, and incorporating PoCUS into clinical decisions and procedural guidance. Students completed a 30-question pre- and posttest focused on ultrasound and knowledge of clinical concepts. PoCUS educators from 10 different specialties delivered the course over 10 days using video-conferencing software. Students watched live scanning demonstrations and practiced ultrasound probe maneuvers using a cellular telephone to simulate ultrasound probe. Students completed daily course evaluations that were used as a continuous needs assessment to make improvements. RESULTS A total of 141 students participated in the course; all received a passing grade. The mean pre- and posttest scores improved from 58% to 88% (p < 0.001) through the course duration. Daily evaluations revealed the percentage of students who rated the course's live scanning sessions and didactic components as "very well" increased from 32.7% on day 1 to 69.7% on day 10. The end-of-course evaluation revealed that 91% of students agreed they received effective teaching. CONCLUSIONS In response to the COVID-19 pandemic, our multispecialty faculty expeditiously developed a virtual PoCUS curriculum for the entire fourth-year class. This innovative course improved students' ultrasound knowledge, image interpretation, and clinical application while utilizing novel techniques to teach a hands-on skill virtually. As the demand for PoCUS instruction continues to increase, the accessibility of virtual training and blended learning will be beneficial.

Abstract
A trend in the increasing use of prescription psychoactive drugs (PADs), including antidepressants, antipsychotics, and mood stabilizers, has been reported in the United States and globally. In addition, there has been an increase in the production and usage of illicit PADs and emergence of new psychoactive substances (NPSs) all over the world. PADs pose unique challenges for critical care providers who may encounter toxicology issues due to drug interactions, side effects, or drug overdoses. This article provides a summary of the toxicologic features of commonly used and abused PADs: antidepressants, antipsychotics, mood stabilizers, hallucinogens, NPSs, caffeine, nicotine, and cannabis.

Abstract
Background Simulation is used in critical care for skill development, formative assessment, and interprofessional team performance. Healthcare educators need to balance the relatively high cost to deliver simulation education with the potential impact on healthcare quality. It is unclear how to prioritize simulation in critical care education, especially considering interprofessional needs across adult and pediatric populations. The objective of this study was to prioritize topics for critical care educators developing simulation-based educational interventions. Methodology A modified Delphi process was used to identify and prioritize critical care topics taught using simulation. We disseminated a multi-institutional survey to understand critical care simulation topics using a three-round modified Delphi technique. An expert panel was recruited based on their expertise with simulation-based education through the Society for Simulation in Healthcare and the Society of Critical Care Medicine lists. Critical care topics originated using content derived from multiple critical care board examination contents. Additional content for a critical care simulation-based curriculum was generated. Results Consensus and prioritization were achieved in three rounds, with 52 simulation experts participating. The first Delphi round surveyed priority topics in critical care content and generated additional topics for inclusion in round two. The second Delphi round added the content with the highest-ranked items from round one to generate a set of simulation-based topic priorities. The third Delphi round asked participants to determine the importance of each priority item taught via simulation compared to other modalities for clinical education. This round yielded 106 topics over four domains categorized into (1) Diagnosis and Management of Clinical Problems, (2) Procedural Skills, (3) Teamwork and Communication Skills, and (4) General Knowledge and Knowledge of Technical Adjuncts. Conclusions The modified Delphi survey revealed a prioritized, consensus-based list of topics and domains for critical care educators to focus on when creating a simulation-based critical care curriculum. Future work will focus on developing specific simulation-based critical care curricula.

BACKGROUND Hands-on ultrasound experience has become a desirable component for undergraduate medical education (UGME) curricula throughout medical schools in the United States (US) to enhance readiness for future training. Ultrasound integration can be a useful assistive educational method in undergraduate medical education to improve anatomy and physiology skills. Relatively few medical schools have integrated ultrasound experiences formally into their 4-year medical school curriculum due to limitations of a resource intensive set up. METHODS We undertook a scoping review of published UGME ultrasound curricula integrated into all four years in peer-reviewed as well online literature. In addition, we provide a narrative review of our institutional experience in conceptualization, design and implementation of UGME ultrasound curriculum driven by need to address the fading knowledge in anatomy and physiology concepts beyond pre-clinical years. RESULTS Integrated ultrasound curriculum at WFSOM utilizes focused ultrasonography as a teaching aid for students to gain a more thorough understanding of basic and clinical science concepts taught in the medical school curriculum. We found 18 medical schools with ultrasound curricula published in peer-reviewed literature with a total of 33 ultrasound programs discovered by adding Google search and personal communication CONCLUSIONS: The results of the review and our institutional experience can help inform future educators interested in developing similar curricula in their undergraduate programs. Common standards, milestones and standardized competency-based assessments would be helpful in more widespread application of ultrasound in UGME curricula.

Abstract
Laminectomy, a common neurosurgical procedure that decompresses the spinal cord, is the definitive surgical treatment for spinal epidural abscesses. Although complications after laminectomy occur infrequently, they can cause significant morbidity and health care resource usage. These complications include soft tissue collections like a persistent and/or new abscess or a hematoma. The preferred method of diagnosis for spinal soft tissue collections is magnetic resonance imaging. However, traditional neuroimaging poses significant challenges in patients with spinal hardware due to metallic artifact precluding appropriate visualization of anatomy and pathology. This was a case of a patient with extensive spinal hardware where visualization of the spinal cord by postoperative sonography was made feasible by a lack of bone after a laminectomy. Point-of-care ultrasound, a convenient bedside tool with the ability to detect soft tissue collections easily, was used to monitor for postoperative recurrence of a spinal epidural abscess in this patient. Patients with an intact spine do not have adequate acoustic windows due to posterior vertebral anatomy. In postlaminectomy patients without posterior vertebral structures, sonography may offer a diagnostic modality for postoperative monitoring. Ultrasonographers can employ spinal cord sonography, particularly when the indication for decompressive laminectomy was a localized fluid collection or abscess.

Abstract
BACKGROUND AND PURPOSE Patients with acute ischemic stroke receive computed tomography angiogram (CTA) and digital subtraction angiogram (DSA) for clinical evaluation. Current guidelines lack in defining indications for transcranial Doppler (TCD) and/or carotid duplex ultrasonography (CUS) in acute stroke evaluation or follow-up cerebrovascular imaging after reperfusion. We investigated the clinical utility of performing additional TCD/CUS after reperfusion in guiding postacute care stroke management. METHODS Retrospective review of acute ischemic stroke patients admitted to a comprehensive stroke center with CTA head and neck and/or DSA followed by TCD/CUS. Cases were reviewed by two authors to determine if TCD/CUS provided additional diagnostic information to aid management. A nominal group process, using a third author, achieved consensus in cases of disagreements. RESULTS Only 25 of 198 patients had CTA or DSA followed by TCD/CUS. Ten (40%) cases showed new clinical information from CUS aiding management. Of those with TCD, 5 patients (22.7%) had findings that impacted management. These clinical scenarios included detection of mobile thrombus requiring anticoagulation; distinguishing carotid near-occlusion from occlusion; confirming hemodynamic significance of intra/extracranial stenosis helping emergent stenting/endarterectomy; detecting hyperperfusion on TCDs causing symptoms; and establishing chronicity of carotid stenosis based on collateral flow patterns, which deferred further intervention. DISCUSSION Our experience shows that TCD/CUS may offer additional diagnostic information assisting postacute care management in small subset of patients with acute ischemic stroke. Larger studies are needed to research the clinical impact and cost-effectiveness of additional imaging and inform clinical guidelines for selecting patients who will benefit from these additional studies.

Abstract
BACKGROUND AND PURPOSE Ischemic stroke can occur in 20-55% of patients with infective endocarditis (IE) with 75% occurring during the first 2 weeks of treatment. CT or MRI brain can diagnose the sequelae of stroke but transcranial Doppler (TCD) can document active embolization. We undertook a retrospective review of our patient cohort and a systematic review of literature to assess the role of TCD in early diagnosis and management of ischemic stroke in IE. METHODS Retrospective chart review and literature review. RESULTS We found 89 patients with stroke caused by IE at our institution from December 2011 to April 2018. TCDs were obtained on 26 patients; 16 were abnormal for cerebrovascular abnormalities. Only 4 patients had 30-minute emboli monitoring performed, of which one revealed emboli. We found 3 studies investigating the role of TCDs in IE that showed promise in its use as a predictive tool in stroke risk stratification. CONCLUSIONS Presence of embolization in the form of high-intensity transient signals (HITS) detected on TCDs can be used for early diagnosis of IE, assessing efficacy of antibiotic therapy, and stratification of stroke risk in IE. This can aid further research into testing preventative interventions for reducing stroke burden in IE such as earlier valvular surgery or vacuum-assisted vegetation extraction.

Abstract
OBJECTIVE The emergence of coronavirus disease 2019 (COVID-19) presents a challenge for neurologists caring for patients with preexisting neurologic conditions hospitalized for COVID-19 or for evaluation of patients who have neurologic complications during COVID-19 infection. We conducted a scoping review of the available literature on COVID-19 to assess the potential effect on neurologists in terms of prevalent comorbidities and incidence of new neurologic events in patients hospitalized with COVID-19. METHODS We searched MEDLINE/PubMed, CINAHL (EBSCO), and Scopus databases for adult patients with preexisting neurologic disease who were diagnosed and hospitalized for COVID-19 or reported incidence of secondary neurologic events following diagnosis of COVID-19. Pooled descriptive statistics of clinical data and comorbidities were examined. RESULTS Among screened articles, 322 of 4,014 (8.0%) of hospitalized patients diagnosed and treated for COVID-19 had a preexisting neurologic illness. Four retrospective studies demonstrated an increased risk of secondary neurologic complications in hospitalized patients with COVID-19 (incidence of 6%, 20%, and 36.4%, respectively). Inconsistent reporting and limited statistical analysis among these studies did not allow for assessment of comparative outcomes. CONCLUSION Emerging literature suggests a daunting clinical relationship between COVID-19 and neurologic illness. Neurologists need to be prepared to reorganize their consultative practices to serve the neurologic needs of patients during this pandemic.

Abstract
Prolonged mechanical ventilation promotes diaphragmatic atrophy and weaning difficulty. The study uses a novel device containing a transvenous phrenic nerve stimulating catheter (Lungpacer IntraVenous Electrode Catheter) to stimulate the diaphragm in ventilated patients. We set out to determine the feasibility of temporary transvenous diaphragmatic neurostimulation using this device. DESIGN Multicenter, prospective open-label single group feasibility study. SETTING ICUs of tertiary care hospitals. PATIENTS Adults on mechanical ventilation for greater than or equal to 7 days that had failed two weaning trials. INTERVENTIONS Stimulation catheter insertion and transvenous diaphragmatic neurostimulation therapy up to tid, along with standard of care. MEASUREMENTS AND MAIN RESULTS Primary outcomes were successful insertion and removal of the catheter and safe application of transvenous diaphragmatic neurostimulation. Change in maximal inspiratory pressure and rapid shallow breathing index were also evaluated. Eleven patients met all entry criteria with a mean mechanical ventilation duration of 19.7 days; nine underwent successful catheter insertion. All nine had successful mapping of one or both phrenic nerves, demonstrated diaphragmatic contractions during therapy, and underwent successful catheter removal. Seven of nine met successful weaning criteria. Mean maximal inspiratory pressure increased by 105% in those successfully weaned (mean change 19.7 ± 17.9 cm H2O; p = 0.03), while mean rapid shallow breathing index improved by 44% (mean change -63.5 ± 64.4; p = 0.04). CONCLUSIONS The transvenous diaphragmatic neurostimulation system is a feasible and safe therapy to stimulate the phrenic nerves and induce diaphragmatic contractions. Randomized clinical trials are underway to compare it to standard-of-care therapy for mechanical ventilation weaning.

Abstract
Chronic kidney disease (CKD) independently increases the risk of stroke and small vessel disease (SVD). This study compared SVD and a transcranial Doppler (TCD)-based marker of intracranial vascular resistance (pulsatility index, PI) in post-stroke patients with and without CKD. Between January 2015 and December 2017, 118 individuals with stable eGFR (50 with CKD) had cerebral MRI and TCD within three months of a stroke. The means of bilateral PI in anterior (anterior cerebral [ACA] and middle cerebral arteries [MCA]) and posterior vessels (posterior cerebral [PCA] and vertebral arteries [VA]) were computed. CKD strongly correlated with higher distal resistance (median CKD ACA PI 1.2, IQR 1.0 to 1.35 vs. controls 0.91 IQR 0.79 to 1.1 [p < 0.0001]; median MCA PI 1.14 IQR 1.03 to 1.39 vs. controls 0.93 IQR 0.79 to 1.1 [p < 0.0001]) and MRI SVD burden (median CKD SVD 4.98 × 104 IQR 2.66 to 7.76 × 104 voxels vs. controls median SVD 6.7 × 103 IQR 2.4 to 24.0 × 103 [p < 0.0001]). In conclusion, in patients with recent stroke, CKD is an independent determinant of increased intracranial vascular resistance in both anterior and posterior cerebral circulations. MRI SVD volume is significantly associated with anterior and posterior circulation PI.

Abstract
Simulation-based medical education is a technique that leverages adult learning theory to train healthcare professionals by recreating real-world scenarios in an interactive way. It allows learners to emotionally engage in the assessment and management of critically ill patients without putting patients at risk. Learners are encouraged to work at the edge of their expertise to promote growth and are provided with feedback to nurture development. Thus, the training is targeted to the learner, not the patient. Despite its origins as a teaching tool for neurological diseases, simulation-based medical education has been historically abandoned by neurocritical care educators. In contrast, other critical care educators have embraced the technique and built an impressive foundation of literature supporting its use. Slowly, neurocritical care educators have started experimenting with simulation-based medical education and sharing their results. In this review, we will investigate the historical origins of simulation in the neurosciences, the conceptual framework supporting the technique, current applications, and future directions.

Abstract
BACKGROUND Neurological complications in liver failure are common. Often under-recognized neurological complications are seizures and status epilepticus. These may go unrecognized without continuous electroencephalography (CEEG). We highlight the observed electro-radiological changes in patients with grade III/IV hepatic encephalopathy (HE) found to have seizures and/or status epilepticus on CEEG and the associated neuroimaging. METHODS This study was a retrospective review of patients with West Haven grade III/IV HE and seizures/status epilepticus on CEEG. RESULTS Eleven patients were included. Alcohol was the most common cause of HE (54.5%). All patients were either stuporous/comatose. The most common CEEG pattern was diffuse slowing (100%) followed by generalized periodic discharges (GPDs; 36.4%) and lateralized periodic discharges (LPDs, 36.4%). The subtype of GPDs with triphasic morphology was only seen in 27.3%. All seizures and/or status epilepticus were without clinical signs. Magnetic resonance imaging (MRI) was available in six patients. Cortical hyperintensities on diffusion weighted imaging sequence were seen in all six patients. One patient had CEEG seizure concomitantly with the MRI. Seven patients died prior to discharge. CONCLUSION Seizures or status epilepticus in the setting of HE were without clinical findings and could go unrecognized without CEEG. The finding of cortical hyperintensity on MRI should lead to further evaluation for unrecognized seizure or status epilepticus.

Abstract
AIM To conduct a systematic review and meta-analysis to understand the timing and factors associated with anti-programmed cell death protein-1 (PD-1)/anti-programmed cell death protein-1 ligand (PD-L1) inhibitor-induced Type 1 diabetes. METHODS We searched MEDLINE, EMBASE, SCOPUS and Cochrane databases (August 2000-2018) for studies of any design on immune checkpoint inhibitors. A total of 71 cases were reviewed from 56 publications. Comparisons were made using Fisher's exact and Student's t-tests. RESULTS The mean ± sd age at Type 1 diabetes presentation was 61.7±12.2 years, 55% of cases were in men, and melanoma (53.5%) was the most frequent cancer. The median time to Type 1 diabetes onset was 49 (5-448) days with ketoacidosis in 76% of cases. The average ± sd HbA1c concentration was 62 ± 0.3 mmol/mol (7.84±1.0%) at presentation. All cases had insulin deficiency and required permanent exogenous insulin treatment. Half of the cases had Type 1 diabetes-associated antibodies at presentation, and those with antibodies had a more rapid onset (P=0.005) and higher incidence of diabetic ketoacidosis (P=0.02) compared to people without antibodies. CONCLUSIONS Many people developed Type 1 diabetes within 3 months of initial PD-1/PD-L1 inhibitor exposure. People presenting with Type 1 diabetes-associated antibodies had a more rapid onset and higher incidence of ketoacidosis than those without antibodies. Healthcare providers caring for people receiving these state-of-the-art therapies need to be aware of this potential severe adverse event.

Abstract
AbstractIntracerebral hemorrhage (ICH) accounts for only 10 to 15% of all strokes but remains a significant cause of morbidity and mortality. Despite lengthy stays in critical care units, only one-half of those experiencing an ICH survive after 30 days, and those who do are often left with considerable disability. Treatment has traditionally focused on minimizing the hemorrhage expansion and reducing clot volume through both medical and surgical means. Management of ICH is a complex and multidisciplinary process. This review will discuss a few common etiologies, explore the pathophysiology of secondary neuronal injury after ICH, review the basics of ICH imaging with computed tomography and magnetic resonance imaging, and highlight latest practices in medical and surgical management. Secondary injury mechanisms such as perihematomal edema and disordered cerebral autoregulation are discussed as potential targets for new treatment modalities. Emergent treatment in the “golden hour” after ictus provides a template of measures to adopt from initial contact with emergency medical services, to the emergency department, and thereafter, triage to the intensive care unit. Medical management including blood pressure control, hemostasis, and coagulopathy reversal are discussed and evidence from trials such as INTERACT 2, ATACH 2, and ANNEXA-4 are given a clinical context. Surgical management including intracranial pressure monitoring, surgical evacuation with open craniotomy, and minimally invasive approaches such as stereotactic-guided aspiration and thrombolysis, ultrasound-induced thrombolysis, image-guided stereotactic endoscopic aspiration, and stereotactic ICH underwater blood aspiration are enumerated. The outcomes and relevance of STICH, MISTIE, and CLEAR trials to present surgical care are elaborated. The review summarizes the current guidelines for the treatment of ICH and the latest literature in the field they are based upon. It aims to provide a concise article beneficial to the emergency physicians and neurointensivists/neuroanesthesiologists.

Abstract
Brain ultrasonography can be used to evaluate cerebral anatomy and pathology, as well as cerebral circulation through analysis of blood flow velocities. Transcranial colour-coded duplex sonography is a generally safe, repeatable, non-invasive, bedside technique that has a strong potential in neurocritical care patients in many clinical scenarios, including traumatic brain injury, aneurysmal subarachnoid haemorrhage, hydrocephalus, and the diagnosis of cerebral circulatory arrest. Furthermore, the clinical applications of this technique may extend to different settings, including the general intensive care unit and the emergency department. Its increasing use reflects a growing interest in non-invasive cerebral and systemic assessment. The aim of this manuscript is to provide an overview of the basic and advanced principles underlying brain ultrasonography, and to review the different techniques and different clinical applications of this approach in the monitoring and treatment of critically ill patients.

Abstract
Background: Patients with intracerebral hemorrhages (ICHs) have higher incidence of seizures. Previous studies have suggested that location and size of hemorrhage may increase epileptogenicity. We aim to evaluate seizure development risk factors from clinical examination, imaging, and continuous electroencephalography (cEEG) in critically ill patients with ICH. Methods: We reviewed 57 consecutive patients with ICH admitted to a neurocritical intensive care unit over a 24-month period who were monitored on cEEG. Their demographic and examination data, ICH score, Glasgow Coma Scale (GCS), location of bleed, cEEG patterns, and discharge status were analyzed. Results: Sixteen (28%) patients from our study cohort had seizures at a mean duration of 7.46 h from cEEG hookup. Fifteen (93%) of those patients had only electrographic seizures. The finding of lateralized periodic discharges (LPDs) was significantly (P = 0.019) associated with seizures. Other variables, such as ICH score, size and location of hemorrhage, GCS, mental status, and other cEEG patterns, were not significantly associated with seizures. Conclusion: We found that LPDs were predictive of seizures in ICH patients. cEEG for longer than 24 h is preferred for detection of seizures as they occurred at a mean later than 7 h and most were without clinical signs.
