The COVID-19 pandemic, an environmental neurology perspective.

Neurologists have a particular interest in SARS-CoV-2 because the nervous system is a major participant in COVID-19, both in its acute phase and in its persistent post-COVID phase. The global spread of SARS-CoV-2 infection has revealed most of the challenges and risk factors that humanity will face in the future. We review from an environmental neurology perspective some characteristics that have underpinned the pandemic. We consider the agent, SARS-CoV-2, the spread of SARS-CoV-2 as influenced by environmental factors, its impact on the brain and some containment measures on brain health. Several questions remain, including the differential clinical impact of variants, the impact of SARS-CoV-2 on sleep and wakefulness, and the neurological components of Long-COVID syndrome. We touch on the role of national leaders and public health policies that have underpinned management of the COVID-19 pandemic. Increased awareness, anticipation and preparedness are needed to address comparable future challenges.

Frequency and Referral Patterns of Neural Antibody Studies During the COVID-19 Pandemic: Experience From an Autoimmune Neurology Center.

OBJECTIVE: To determine whether the frequency of paraneoplastic or autoimmune encephalitis antibodies examined in a referral center changed during the COVID-19 pandemic. METHODS: The number of patients who tested positive for neuronal or glial (neural) antibodies during pre-COVID-19 (2017-2019) and COVID-19 (2020-2021) periods was compared. The techniques used for antibody testing did not change during these periods and included a comprehensive evaluation of cell-surface and intracellular neural antibodies. The chi-square test, Spearman correlation, and Python programming language v3 were used for statistical analysis. RESULTS: Serum or CSF from 15,390 patients with suspected autoimmune or paraneoplastic encephalitis was examined. The overall positivity rate for antibodies against neural-surface antigens was similar in the prepandemic and pandemic periods (neuronal 3.2% vs 3.5%; glial 6.1 vs 5.2) with a mild single-disease increase in the pandemic period (anti-NMDAR encephalitis). By contrast, the positivity rate for antibodies against intracellular antigens was significantly increased during the pandemic period (2.8% vs 3.9%, p = 0.01), particularly Hu and GFAP. DISCUSSION: Our findings do not support that the COVID-19 pandemic led to a substantial increase of known or novel encephalitis mediated by antibodies against neural-surface antigens. The increase in Hu and GFAP antibodies likely reflects the progressive increased recognition of the corresponding disorders.

Virtual Adaptation of an International Exchange Program in Medical Education.

Medical education has drastically transformed during the COVID-19 pandemic. Measures such as adopting telemedicine visits, minimizing the number of trainees on service, discontinuing external rotations, and converting in-person to online didactics have been broadly and swiftly implemented. While these innovations have promoted greater interconnectivity amongst institutions and made continuing medical education possible, international exchange programs in medical education are still largely disrupted. In response to the changing guidelines and restrictions necessitated by the COVID-19 pandemic, the authors used Kern's six-step approach to design and implement a virtual curriculum to replace the in-person activities of the 2020-2021 Neurology Peru-Rochester exchange program (NeuroPro). Twenty-seven trainees participated in this virtual adaptation. The average daily attendance was ≥85% and the program was rated 9/10 on average in a feedback survey (63% response rate). The median percentage of correct answers during the pre-test was 64% and it increased to 79% during the post-test (P = 0.003). Virtual adaptation of international exchange programs in medical education is feasible to safely continue international collaborative efforts to promote symbiotic building of local expertise and cross-cultural exchange during the ongoing COVID-19 pandemic and beyond.

Audio or Video? Access to Pediatric Neurology Outpatient Services Varies by the Type of Telehealth, Especially for Black Children.

BACKGROUND: Children of minority race/ethnicity face barriers to accessing specialty services. During the COVID pandemic, health insurance companies reimbursed telehealth services. Our objective was to evaluate the effect of audio versus video visits on children's access to outpatient neurology services, particularly for Black children. METHODS: Using Electronic Health Record data, we collected information about children who had outpatient neurology appointments in a tertiary care children's hospital in North Carolina from March 10, 2020, to March 9, 2021. We used multivariable models to compare appointment outcomes (canceled vs completed, and missed vs completed) by visit type. We then conducted similar evaluation for the subgroup of Black children. RESULTS: A total of 1250 children accounted for 3829 scheduled appointments. Audio users were more likely to be Black and Hispanic, and to have public health insurance than video users. Adjusted odds ratio (aOR) for appointments completed versus canceled was 10 for audio and 6 for video, compared to in-person appointments. Audio visits were twice as likely as in-person visits to be completed versus missed; video visits were not different. For the subgroup of Black children, aOR for appointments completed versus canceled for audio was 9 and video was 5, compared to in-person appointments. For Black children, audio visits were 3 times as likely as in-person visits to be completed versus missed; video visits were not different. CONCLUSIONS: Audio visits improved access to pediatric neurology services, especially for Black children. Reversal of policies to reimburse audio visits could deepen the socioeconomic divide for children's access to neurology services.

The relationship of online pre-recorded neurology mini-lectures to medical student assessment: a pilot study.

INTRODUCTION: eLearning has become an essential part of medical education. However, there is a lack of published research on student engagement with online pre-recorded mini-lectures and its relation to assessment. The aim of this pilot study is to explore the relationship between newly introduced neurology pre-recorded mini-lectures and undergraduate medical students engagement and assessment. This may encourage the wider use of mini-lectures in undergraduate medical curricula. METHODS: The engagement of medical students with 48 online pre-recorded neurology mini-lectures was assessed through a Learning Management System. To measure engagement, data was stratified according to the number of watched/downloaded mini-lectures. A point system was used (out of 5): - 1 point = watching/downloading 0-10 mini-lectures, 2 points = watching/downloading 11-20 mini-lectures, 3 points = watching/downloading 21-30 mini-lectures, 4 points = watching/downloading 31-40 mini-lectures and, 5 points = watching/downloading 41-48 mini-lectures. The students' engagement was correlated with their neurology assessments [Objective Structured Clinical Examination (OSCE), and knowledge-based assessment 10 Multiple Choice Questions (MCQs) and one 10-mark Short Answer Question, (SAQ)], internal medicine grade and annual grade point average (GPA) using the Pearson correlation coefficient. RESULTS: The mean engagement of 34, Year 5, medical students is 3.9/5. There is a significant positive correlation between engagement and internal medicine grade (r = 0.35, p = 0.044). There is a moderate correlation between engagement and neurology OSCE (r = 0.23), annual Year 5 GPA (r = 0.23), neurology knowledge-based score (r = 0.22) and composite neurology knowledge/OSCE (r = 0.27). The knowledge-based assessment included SAQ and MCQs: there was a moderate correlation with SAQ (r = 0.30), but a weak negative correlation with the MCQs (r =-0.11). Sub-groups analysis comparing the top- and low- or non- engaging students made these weaker correlations stronger. CONCLUSION: This pilot study indicates a high rate of engagement with an online pre-recorded mini-lectures resource and evidence of moderate correlation between engagement and assessment. Online pre-recorded mini-lectures should be used more in delivering the curriculum contents of the clinical clerkships. Further studies are needed to evaluate the relation and the impact of the mini-lectures on assessment.

An eye to the future: Acute and long-term neuro-ophthalmological and neurological complications of COVID-19.

COVID-19 has had a significant impact on the global population and has produced compelling evidence of non-pulmonary organ dysfunction, including the nervous system. It is vital that specialists in ophthalmology and neurology are informed of the potential complications of COVID-19 and gain a deeper understanding of how COVID-19 can cause diseases of the nervous system. In this review we detail four possible mechanisms by which COVID-19 infection may result in neurological or neuro-ophthalmological complications: (1) Toxic and metabolic effects of severe pulmonary COVID-19 disease on the neural axis including hypoxia and the systemic hyper-inflammatory state, (2) endothelial dysfunction, (3) dysimmune responses directed again the neuroaxis, and (4) direct neuro-invasion and injury by the virus itself. We explore the pathological evidence for each of these and how they may link to neuro-ophthalmological disorders. Finally, we explore the evidence for long-term neurological and neuro-ophthalmological complications of COVID-19, with a focus on neurodegeneration.

A Multidisciplinary Pediatric Neurology Clinic for Systematic Follow-up of Children with Neurologic Sequelae of COVID-19.

Clinical guidance on outpatient follow-up of children hospitalized with acute neurologic complications of SARS-CoV2 infection is needed. We describe the clinical infrastructure of our pediatric neurology post-Covid clinic, including our clinical evaluation and cognitive testing battery specific to this patient population, and a case series of our initial patient cohort. Our findings demonstrate cognitive sequelae in all 4 of our patients months following acute SARS-CoV2 infection with neurologic complications including acute disseminated encephalomyelitis, posterior reversible encephalopathy syndrome, viral encephalitis, and gait difficulties. Verbal and executive function domains were predominantly affected in our cohort, even in patients who did not endorse symptomatic or academic complaints at follow-up. Our recommendations include systematic clinical follow-up for children following hospitalization with SARS-CoV2 infection with a comprehensive cognitive battery to monitor for cognitive sequalae and to assist with developing an individualized education plan for the child as they return to school.

Reduction of No-Show Rate for New Patients in a Pediatric Neurology Clinic.

BACKGROUND: The rate of patients not keeping their appointments at our children's hospital outpatient pediatric neurology clinic (no-shows) was high. We conducted a quality improvement project to reduce no-show rates and improve operational efficiency. Specifically, we aimed to decrease the new patient no-show mean rate from 7% to 4% at the main campus and from 17% to 12% at the south campus. METHODS: After reviewing the previous literature on this topic and institutional data, we used the simplified failure mode and effects analysis (sFMEA) to identify the key drivers. Of the patients at the main campus who failed to keep their appointment, 84% had not confirmed their appointment. Errors in inpatient/family contact information, limited use of the electronic patient portal, and miscommunication were other key drivers identified. Three Plan-Do-Study-Act (PDSA) cycles were completed over seven months. The key interventions we implemented were bidirectional text triage, telephone reminders, and promoting the use of the electronic patient portal. A run chart was used to assess the results of these interventions. RESULTS: A statistically significant shift was noted in the run chart for the median rate of no-shows, which declined from 7% to 4% at the main campus and 17% to 10% at the south campus. CONCLUSION: We were able to successfully reduce no-shows among new patients in the neurology clinic. The limitations of our study include unknown external factors, the potential impact of COVID-19, and the brief length of the study.

Black Patients Matter in Neurology: Race, Racism, and Race-Based Neurodisparities.

Black people living in the United States suffer disproportionate morbidity and mortality across a wide range of neurologic conditions. Despite common conceptions to the contrary, "race" is a socially defined construct with little genetic validity. Therefore, racial health inequities in neurology ("neurodisparities") are not a consequence of biologic differences between races. Instead, racism and associated social determinants of health are the root of neurodisparities. To date, many neurologists have neglected racism as a root cause of neurologic disease, further perpetuating the problem. Structural racism, largely ignored in current neurologic practice and policy, drives neurodisparities through mediators such as excessive poverty, inferior health insurance, and poorer access to neurologic and preventative care. Interpersonal racism (implicit or explicit) and associated discriminatory practices in neurologic research, workforce advancement, and medical education also exacerbate neurodisparities. Neurologists cannot fulfill their professional and ethical responsibility to care for Black patients without understanding how racism, not biologic race, drives neurodisparities. In our review of race, racism, and race-based disparities in neurology, we highlight the current literature on neurodisparities across a wide range of neurologic conditions and focus on racism as the root cause. We discuss why all neurologists are ethically and professionally obligated to actively promote measures to counteract racism. We conclude with a call for actions that should be implemented by individual neurologists and professional neurologic organizations to mitigate racism and work towards health equity in neurology.

The Top 100 Most Cited Neurosurgical Articles on COVID-19: A Bibliometric Analysis.

BACKGROUND: The first case of coronavirus disease 2019 (COVID-19) was reported in December 2019 in Wuhan, China. This study uses a bibliometric analysis of the top 100 most cited neurosurgical COVID-19-related articles to date to identify and determine their characteristics. METHODS: The Scopus library was searched for all published articles on neurosurgery and COVID-19. The main keywords were used for the search "neurosurgery, neurosurgical, and COVID-19". English language articles reporting on neurosurgical aspects during COVID-19 were included in the study. The retrieved top 100 articles were analyzed, and the following characteristics were noted for each article: 1) article title, 2) year of publication, 3) citations, 4) first author, 5) corresponding author, 6) names of other authors, 7) journal name 8) article type, 9) study focus and 10) involvement of the patient. RESULTS: Our search obtained articles published from December 2019 until 29 March 2022. It was observed that 93% of the documents were published in 2020. The top 100 articles have been cited 2649 times in total. The most cited article was "Factors Associated with Surgical Mortality and Complications among Patients with and without Coronavirus Disease 2019 (COVID-19) in Italy" by Doglietto F. et al., published in JAMA Neurology in June 2020, with 124 citations. CONCLUSIONS: This analysis facilitated in making evidence-based clinical decisions and drawing the attention of researchers to identify and contribute to the increasing scientific work by identifying the top 100 most cited neurosurgical COVID-19-related articles published.

Can Tele-Neuro-Ophthalmology Be Useful Beyond the Pandemic?

PURPOSE OF THE REVIEW: Neuro-ophthalmologists rapidly adopted telehealth during the COVID-19 pandemic to minimize disruption to patient care. This article reviews recent research on tele-neuro-ophthalmology adoption, current limitations, and potential use beyond the pandemic. The review considers how digital transformation, including machine learning and augmented reality, may be applied to future iterations of tele-neuro-ophthalmology. RECENT FINDINGS: Telehealth utilization has been sustained among neuro-ophthalmologists throughout the pandemic. Adoption of tele-neuro-ophthalmology may provide solutions to subspecialty workforce shortage, patient access, physician wellness, and trainee educational needs within the field of neuro-ophthalmology. Digital transformation technologies have the potential to augment tele-neuro-ophthalmology care delivery by providing automated workflow solutions, home-based visual testing and therapies, and trainee education via simulators. Tele-neuro-ophthalmology use has and will continue beyond the COVID-19 pandemic. Digital transformation technologies, when applied to telehealth, will drive and revolutionize the next phase of tele-neuro-ophthalmology adoption and use in the years to come.

[Neurointensive care medicine and COVID-19]. / Neurointensivmedizin und COVID-19.

This review article summarizes important findings on the interfaces between the coronavirus disease 2019 (COVID-19) pandemic and neurology with an emphasis of the implications for neurointensive care medicine. More specifically, the prevalence, pathomechanisms and impact of neurological manifestations are reported. The most common neurological manifestations of critically ill COVID-19 patients are cerebrovascular complications, encephalopathies and intensive care unit-acquired weakness (ICUAW). A relevant direct pathophysiological effect by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) itself has not yet been established with certainty. In fact, indirect systemic inflammatory processes triggered by the viral infection and side effects of intensive care treatment are much more likely to cause the reported sequelae. The impact of the pandemic on patients with neurological disorders and neurointensive care medicine is far-reaching but not yet sufficiently studied.
