Introducción: Las nuevas tecnologías (NT) están cada vez más presentes en el ámbito biomédico. Utilizando la definición de consenso de NT del Comité Ad-Hoc de Nuevas Tecnologías de la Sociedad Española de Neurología (SEN), se evalúa su impacto en la neurología española a través de las comunicaciones de las reuniones anuales de la SEN. Material y métodos: Se define el concepto de NT en neurología como una tecnología novedosa o aplicación de una tecnología anterior, caracterizada por un cierto grado de coherencia persistente en el tiempo, con potencial de tener impacto en el presente y futuro de la neurología. Se plantea un estudio descriptivo tomando como fuente las comunicaciones de las reuniones de la SEN desde 2012 hasta 2018 y analizando los tipos de NT empleadas, la subespecialidad, así como su distribución territorial. Resultados: De las 8.139 comunicaciones presentadas, 299 estaban relacionadas con NT (3,7%), incluyendo 120 pósteres y 179 comunicaciones orales, variando desde el 1,6% en 2012 hasta el 6,8% en 2018. Los tipos de tecnología mayormente representados fueron neuroimagen avanzada (24,7%), biosensores (17,1%), electrofisiología y neuroestimulación (14,7%) y telemedicina (13,7%). Las áreas neurológicas con mayor empleo de NT fueron trastornos del movimiento (18,4%), enfermedades cerebrovasculares (15,7%) y demencias (13,4%). Madrid fue la comunidad que presentó más comunicaciones (32,8%), seguida por Cataluña (26,8%) y Andalucía (9,0%). Conclusiones: Las comunicaciones sobre NT siguen una tendencia creciente. El número de NT empleadas ha ido aumentando de manera paralela a la disponibilidad tecnológica. Se encontraron comunicaciones en todas las subespecialidades neurológicas, con una distribución geográfica heterogénea.(AU)

Introduction: New technologies (NT) are increasingly widespread in biomedicine. Using the consensus definition of NT established by the New Technologies Ad-Hoc Committee of the Spanish Society of Neurology (SEN), we evaluated the impact of these technologies on Spanish neurology, based on communications presented at Annual Meetings of the SEN. Material and methods: We defined the concept of NT in neurology as a novel technology or novel application of an existing technology, characterised by a certain degree of coherence persisting over time, with the potential to have an impact on the present and/or future of neurology. We conducted a descriptive study of scientific communications presented at the SEN's annual meetings from 2012 to 2018, analysing the type of NT, the field of neurology, and the geographical provenance of the studies. Results: We identified 299 communications related with NT from a total of 8,139 (3.7%), including 120 posters and 179 oral communications, ranging from 1.6% of all communications in 2012 to 6.8% in 2018. The technologies most commonly addressed were advanced neuroimaging (24.7%), biosensors (17.1%), electrophysiology and neurostimulation (14.7%), and telemedicine (13.7%). The neurological fields where NT were most widely employed were movement disorders (18.4%), cerebrovascular diseases (15.7%), and dementia (13.4%). Madrid was the region presenting the highest number of communications related to NT (32.8%), followed by Catalonia (26.8%) and Andalusia (9.0%). Conclusions: The number of communications addressing NT follows an upward trend. The number of NT used in neurology has increased in parallel with their availability. We found scientific communications in all neurological subspecialties, with a heterogeneous geographical distribution.(AU)

Global synergistic actions to improve brain health for human development.

The global burden of neurological disorders is substantial and increasing, especially in low-resource settings. The current increased global interest in brain health and its impact on population wellbeing and economic growth, highlighted in the World Health Organization's new Intersectoral Global Action Plan on Epilepsy and other Neurological Disorders 2022-2031, presents an opportunity to rethink the delivery of neurological services. In this Perspective, we highlight the global burden of neurological disorders and propose pragmatic solutions to enhance neurological health, with an emphasis on building global synergies and fostering a 'neurological revolution' across four key pillars - surveillance, prevention, acute care and rehabilitation - termed the neurological quadrangle. Innovative strategies for achieving this transformation include the recognition and promotion of holistic, spiritual and planetary health. These strategies can be deployed through co-design and co-implementation to create equitable and inclusive access to services for the promotion, protection and recovery of neurological health in all human populations across the life course.

[Current Situation and Issues in Transitional Medicine: A Pediatric Neurology Viewpoint].

The transition from pediatric neurology to adult neurology is not easy for patients with childhood-onset neurological or muscular diseases. The reasons can be broadly categorized into patient-related and transition system issues. To resolve these issues, the following are important: 1)promoting awareness of the necessity of future transition among patients and their families during childhood, 2)establishing a transition support team to coordinate the transitions and collect information about medical institutions for adults that can accept patients who need transition, and above all, 3)facilitating close communication and information sharing between the concerned adult and pediatric neurologists.

Low online search interest in teleneurology before and during COVID-19 pandemic: an infodemiological study.

BACKGROUND: The conduct of patient consults greatly changed during the time of the COVID-19 pandemic. There was a decrease in face-to-face patient consults and enhanced utilization of virtual consults. Infodemiological studies, using Google Trends, focus on internet search trends that may reflect public interest and awareness in diseases and as a proxy of public health risk perception. OBJECTIVES: We aimed to investigate the online behavior of internet users on teleneurology, telehealth, and telemedicine during the time of the pandemic, as reflected in search volume indices (SVI) projected in Google Trends. METHODS: We used the data from Google Trends to quantify the interest of internet users in teleneurology, telehealth, and telemedicine. These keywords were entered in Google Trends as search terms. Data included were searches conducted from 2016 to 2020 to depict the transition into the pandemic. RESULTS: The SVI of teleneurology was unchanged during the 5-year period search relative to the SVIs of telehealth and telemedicine. Contrary to the noted worldwide increase in the SVI of telehealth and telemedicine during the year of pandemic, teleneurology's SVI remained stable despite the increase of its utilization. Focusing on teleneurology, the highest SVI was observed in 2018. CONCLUSION: There was an increase in the SVI of telehealth and telemedicine, possibly implying an increase in the general awareness of these virtual methods of health care, as catalyzed by the pandemic. However, the stable SVI of teleneurology may signify that the public awareness regarding it remained unchanged despite the increase in application in clinics and hospitals.

Patient perspectives in pediatric neurology: a critical shift in the paradigm of outcome measurement.

This review explores children's self-reported outcome measurements in pediatric neurology. We examine the following questions: (1) What is meant by patient-reported health, functioning, and quality of life outcomes? (2) How can patients express whether the interventions they receive do more good than harm? (3) Why and how should pediatric neurology patients help determine the outcomes of interest? (4) What tools and recommendations are available to evaluate the outcomes of interest? Applying patients' perspectives across the processes of evaluation of medical interventions has become an important expectation. These developments, consistent with current healthcare goals, coincide with the evolution of pediatric neurology into a sophisticated diagnostic-interventional field that aims to prolong survival, decrease impairments and symptoms, and improve patients' well-being - the recognized essential endpoints of interest in all medicine.

Secondary Immunodeficiency and Risk of Infection Following Immune Therapies in Neurology.

Secondary immunodeficiencies (SIDs) are acquired conditions that may occur as sequelae of immune therapy. In recent years a number of disease-modifying therapies (DMTs) has been approved for multiple sclerosis and related disorders such as neuromyelitis optica spectrum disorders, some of which are frequently also used in- or off-label to treat conditions such as chronic inflammatory demyelinating polyneuropathy (CIDP), myasthenia gravis, myositis, and encephalitis. In this review, we focus on currently available immune therapeutics in neurology to explore their specific modes of action that might contribute to SID, with particular emphasis on their potential to induce secondary antibody deficiency. Considering evidence from clinical trials as well as long-term observational studies related to the patients' immune status and risks of severe infections, we delineate long-term anti-CD20 therapy, with the greatest data availability for rituximab, as a major risk factor for the development of SID, particularly through secondary antibody deficiency. Alemtuzumab and cladribine have relevant effects on circulating B-cell counts; however, evidence for SID mediated by antibody deficiency appears limited and urgently warrants further systematic evaluation. To date, there has been no evidence suggesting that treatment with fingolimod, dimethyl fumarate, or natalizumab leads to antibody deficiency. Risk factors predisposing to development of SID include duration of therapy, increasing age, and pre-existing low immunoglobulin (Ig) levels. Prevention strategies of SID comprise awareness of risk factors, individualized treatment protocols, and vaccination concepts. Immune supplementation employing Ig replacement therapy might reduce morbidity and mortality associated with SIDs in neurological conditions. In light of the broad range of existing and emerging therapies, the potential for SID warrants urgent consideration among neurologists and other healthcare professionals.

The COVID-19 pandemic has had a profound impact on neuroscientists, including those involved in translational research. In this NeuroView, we discuss the positive and negative effects of the pandemic on preclinical research and clinical studies in humans.

Top Priorities for Cerebroprotective Studies-A Paradigm Shift: Report From STAIR XI.

Despite years of basic research and pioneering clinical work, ischemic stroke remains a major public health concern. Prior STAIR (Stroke Treatment Academic Industry Roundtable) conferences identified both failures of clinical trial design and failures in preclinical assessment in developing putative ischemic stroke treatments. At STAIR XI, participants in workshop no. 1 Top Priorities for Neuroprotection sought to redefine the neuroprotection paradigm and given the paucity of evidence underlying preclinical assessment, offer consensus-based recommendations. STAIR proposes the term brain cytoprotection or cerebroprotection to replace the term neuroprotection when the intention of an investigation is to demonstrate that a new, candidate treatment benefits the entire brain. Although "time is still brain," tissue imaging techniques have been developed to identify patients with both predicted core injury and penumbral, salvageable brain tissue, regardless of time after stroke symptom onset. STAIR XI workshop participants called this imaging approach a tissue window to select patients for recanalization. Elements of the neurovascular unit show differential vulnerability evolving over differing time scales in different brain regions. STAIR proposes the term target window to suggest therapies that target the different elements of the neurovascular unit at different times. Based on contemporary principles of rigor and transparency, the workshop updated, revised, and enhanced the STAIR preclinical recommendations for developing new treatments in 2 phases: an exploratory qualification phase and a definitive validation phase. For new, putative treatments, investigators should carefully characterize the mechanism of action, the pharmacokinetics/pharmacodynamics, demonstrate target engagement, and confirm penetration through the blood-brain barrier. Before clinical trials, testing of candidate molecules in stroke models could proceed in a comprehensive manner using animals of both sexes and to include significant variables such as age and comorbid conditions. Comprehensive preclinical assessment might include multicenter, collaborative testing, for example, network trials. In the absence of a proven cerebroprotective agent to use as a gold standard, however, it remains speculative whether such comprehensive preclinical assessment can effectively predict clinical outcome.

Neurology in a Pandemic.

The adaption of online or virtual technologies to deliver care, to meet professionally, and to interview has transformed child neurology. Although these technologies were brought to bear out of necessity, it is hoped that in a postpandemic world, these useful tools will continue to benefit the field. Here we discuss the tools and their future.

Innovations in Neuro-Oncology.

Although outcomes for many brain tumors, especially glioblastomas, remain poor, there have been significant advances in clinical and scientific understanding of neuro-oncologic disease. Tumor molecular profiling has become a critical component of clinical practice, allowing more accurate pathologic diagnosis and enhanced clarity of the pathogenesis of both primary and metastatic brain tumors. The development of cerebral organoids carries exciting potential to provide representative models of tumor growth and potential drug efficacy, while new radiology techniques continue to improve clinical decision making. New adaptive trial platforms have been developed to rapidly test therapies and biomarkers with good scientific rationale. Lastly, growth and development of neuro-oncology clinical care teams aim to further improve patients' outcomes and symptoms, especially at the end of life.

Current Status and Future Strategies for Mentoring Women in Neurology.

The American Academy of Neurology's (AAN) 2017 Gender Disparity Report identified improving mentorship as a key intervention to fill the leadership and pay gaps for women in neurology. Here we summarize the literature on mentoring women, provide an outline of ideal components of programs geared toward closing gender gaps, and present a mentoring program for AAN members. The strategies discussed share similarities with those for closing gaps related to race, ethnicity, and religion. Developing effective mentorship and sponsorship programs is essential to ensure a sufficiently diverse pool of academic faculty and private practitioners and to establish equal representation in leadership roles in this field.

Neurology and neuropsychiatry of COVID-19: a systematic review and meta-analysis of the early literature reveals frequent CNS manifestations and key emerging narratives.

There is accumulating evidence of the neurological and neuropsychiatric features of infection with SARS-CoV-2. In this systematic review and meta-analysis, we aimed to describe the characteristics of the early literature and estimate point prevalences for neurological and neuropsychiatric manifestations.We searched MEDLINE, Embase, PsycINFO and CINAHL up to 18 July 2020 for randomised controlled trials, cohort studies, case-control studies, cross-sectional studies and case series. Studies reporting prevalences of neurological or neuropsychiatric symptoms were synthesised into meta-analyses to estimate pooled prevalence.13 292 records were screened by at least two authors to identify 215 included studies, of which there were 37 cohort studies, 15 case-control studies, 80 cross-sectional studies and 83 case series from 30 countries. 147 studies were included in the meta-analysis. The symptoms with the highest prevalence were anosmia (43.1% (95% CI 35.2% to 51.3%), n=15 975, 63 studies), weakness (40.0% (95% CI 27.9% to 53.5%), n=221, 3 studies), fatigue (37.8% (95% CI 31.6% to 44.4%), n=21 101, 67 studies), dysgeusia (37.2% (95% CI 29.8% to 45.3%), n=13 686, 52 studies), myalgia (25.1% (95% CI 19.8% to 31.3%), n=66 268, 76 studies), depression (23.0% (95% CI 11.8% to 40.2%), n=43 128, 10 studies), headache (20.7% (95% CI 16.1% to 26.1%), n=64 613, 84 studies), anxiety (15.9% (5.6% to 37.7%), n=42 566, 9 studies) and altered mental status (8.2% (95% CI 4.4% to 14.8%), n=49 326, 19 studies). Heterogeneity for most clinical manifestations was high.Neurological and neuropsychiatric symptoms of COVID-19 in the pandemic's early phase are varied and common. The neurological and psychiatric academic communities should develop systems to facilitate high-quality methodologies, including more rapid examination of the longitudinal course of neuropsychiatric complications of newly emerging diseases and their relationship to neuroimaging and inflammatory biomarkers.
