Consensus statement of the Spanish Society of Neurology on the treatment of multiple sclerosis and holistic patient management in 2023.

The last consensus statement of the Spanish Society of Neurology's Demyelinating Diseases Study Group on the treatment of multiple sclerosis (MS) was issued in 2016. Although many of the positions taken remain valid, there have been significant changes in the management and treatment of MS, both due to the approval of new drugs with different action mechanisms and due to the evolution of previously fixed concepts. This has enabled new approaches to specific situations such as pregnancy and vaccination, and the inclusion of new variables in clinical decision-making, such as the early use of high-efficacy disease-modifying therapies (DMT), consideration of the patient's perspective, and the use of such novel technologies as remote monitoring. In the light of these changes, this updated consensus statement, developed according to the Delphi method, seeks to reflect the new paradigm in the management of patients with MS, based on the available scientific evidence and the clinical expertise of the participants. The most significant recommendations are that immunomodulatory DMT be started in patients with radiologically isolated syndrome with persistent radiological activity, that patient perspectives be considered, and that the term "lines of therapy" no longer be used in the classification of DMTs (> 90% consensus). Following diagnosis of MS, the first DMT should be selected according to the presence/absence of factors of poor prognosis (whether epidemiological, clinical, radiological, or biomarkers) for the occurrence of new relapses or progression of disability; high-efficacy DMTs may be considered from disease onset.

Assessment of the Interelectrode Distance Effect over the Omnipole with High Multielectrode Arrays.

The development of high-density multielectrode catheters has significantly advanced cardiac electrophysiology mapping. High-density grid catheters have enabled the creation of a novel technique for reconstructing electrogram (EGM) signals known as "omnipole," which is believed to be more reliable than other methods, especially in terms of orientation independence. This study aims to evaluate how distance affects the omnipolar reconstruction of EGMs by comparing different configurations. Using an animal set up of perfused isolated rabbit hearts, recordings were taken using an ad hoc high-density epicardial multielectrode catheter. Inter-electrode distances ranging from 1 to 4 mm were analysed for their effect on the quality of resulting EGMs. Two biomarkers were computed to evaluate the robustness of the reconstructions: the areas contained within the bipolar loops and the amplitudes of the omnipoles. We hypothesised that both bipolar and omnipolar electrograms would be more robust at shorter inter-electrode distances. The results showed that an increase in distance triggers an increase in loop areas and amplitudes, which supports the hypothesis. This finding provides a more reliable estimate of wavefront propagation for the cross-omnipolar reconstruction method. These results emphasise the importance of distance in cardiac electrophysiology mapping and provide valuable insights into the use of high-density multielectrode catheters for EGM reconstruction.Clinical Relevance- The results of this study have direct clinical relevance in the application of the described techniques to recording systems in the cardiac electrophysiology laboratory, enabling clinicians to obtain more precise characterisation of signals in the myocardium.

Assessing discards in an illegal small-scale fishery using fisher-led reporting.

About a third of all marine fish in the world are caught in Small-Scale Fisheries (SSF). SSF are increasingly recognised as essential for food security and livelihoods for vulnerable and economically fragile communities globally. Although individual SSF vessels are usually perceived as having little impact on the ecosystem, the cumulative impact of gear type and number of vessels may be substantial. Bottom trawling is a common fishing method that can greatly influence the marine ecosystem by damaging the seafloor and generating high levels of discards. However, appropriate sampling coverage using on-board observer programmes to collect these data from SSF are rare, as they are expensive and pose logistical constraints. A mobile App was used to assess whether self-reporting by fishers could provide reliable fine-scale information on fishing effort and discards over time in an illegal shrimp trawling fishery in northern Peru. Maps depicting the spatial distribution of trawling effort and the proportion of discards from observers and fishers were compared using the Similarity in Means (SIM) Index, which ranges from 0 when spatial patterns differ completely to 1 when spatial patterns are very similar. High levels of agreement between spatio-temporal patterns of effort (SIM Index = 0.81) and discards (0.96) were found between fisher and observer maps. Moreover, far greater spatial coverage was accomplished by fishers, suggesting that self-reporting via an App represents a useful approach to collect reliable fisheries data as an initial step for effective monitoring and management of these fisheries.

Occurrence of antibiotics and antibiotic-resistant bacteria (ARB) in the Nervión river.

The main hydrometeorological, microbiological and physico-chemical characteristics of the Nervión river were monitored during a year, including 10 antibiotics and the presence of bacteria resistant to these antibiotics among faecal coliforms (FC) and total aerobic bacteria at 22 °C (TAB22). The characteristics of the river water were variable without a clear seasonal component, strongly influenced by rainfall, with a good quality for drinking water production throughout the year according to the physico-chemical parameters. The antibiotic resistant bacteria isolated from the water of the Nervión river were especially resistant to ß-lactams and macrolide antibiotics, highlighting the absence of resistance to derivatives of tetracyclines among strains of TAB22. A third of the isolated strains were multi-resistant to antibiotics with a seasonal component in its presence, with multi-resistant FC more abundant during summer and multi-resistant TAB22 more abundant during winter. The presence of antibiotics in the waters of the Nervión river was not very significant, with total absence of ß-lactams, minocycline and ciprofloxacin. Erythromycin and clarithromycin can be considered ubiquitous with mean concentrations of 2.5 ± 2.3 ngL-1 and 5.7 ± 4.6 ngL-1 respectively, and the presence of sulfamethoxazole and trimethoprim was also noticeable with maximum concentrations of 78.3 ngL-1 for sulfamethoxazole. Dilution due to the increase of rainfall was observed for several analysed antibiotics, but without significant seasonal differences.

[Air pollution and heart rhythm disturbance: A retrospective study]. / Pollution atmosphérique et troubles du rythme cardiaque : une étude rétrospective.

INTRODUCTION: According to many studies, exposure to air pollution increases cardiovascular morbidity and mortality. It has also been shown that the frequency of heart rhythm disorders in Region wallonne is very high. OBJECTIVES: The objective of this study is to test the hypothesis of a link between rhythm disorders measured by cardiac holters and data from devices measuring the concentration of air pollutants present in ambient air. METHODOLOGY: The health data were obtained via the Erasme hospital's cardiology center. This is a retrospective data collection over the last 2 to 5 years. The environmental data are: PM2.5, PM10, NO2, O3 and temperature. The statistical models were based on "cross-case" analyses. RESULTS: An association between PM10 and the number of ESAs was observed. An increase of 10µg/m3 of PM10 increases the number of ESAs by 20% (P=0.040). The number of ESAs increases with age (63% more ESAs when age increases by 10 years). A history of intervention also decreases the number of ESAs (-35%), the same phenomenon is observed for pacemaker wearers (-66%). The strongest association observed between NO2 and ESA with an OR of 1.37 (P=0.027) in the final model. No significant association was observed between the effects of air pollution and VPCs. CONCLUSION: Our analyses resume the effects of the different pollutants on rhythm disorders, the effects adjusted for treatment and co-morbidities. They open the door to other more refined studies based on individual measurements.

INTRODUCTION: For more than a decade, after the ECTRIMS Congress, Spain has hosted the Post-ECTRIMS meeting, where neurologists with expertise in multiple sclerosis (MS) meet to review the new developments presented at the ECTRIMS. AIM: This article, published in two parts, summarises the presentations of the post-ECTRIMS meeting, held online on 16 and 17 October 2020. DEVELOPMENT: This second part highlights the importance of gender and age in understanding the pathology of the disease and optimising its management. The advances made in paediatric MS, from a neuropsychological and neuroimaging point of view, are presented. In turn, special attention is paid to the findings that contribute to a more personalised approach to therapy and to choosing the best treatment strategy (pharmacological and non-pharmacological) for each patient. Similarly, results related to possible strategies to promote remyelination are addressed. Although there are no major advances in the treatment of progressive forms, some quantitative methods for the classification of these patients are highlighted. In addition, the study also includes results on potential tools for assessment and treatment of cognitive deficits, and some relevant aspects observed in the spectrum of neuromyelitis optica disorders. Finally, the results of the papers considered as breaking news at the ECTRIMS-ACTRIMS are detailed. CONCLUSIONS: Most of the advances presented were related to the knowledge of paediatric MS, remyelination strategies and cognitive assessment in MS.

Characteristics of patients with atrial fibrillation prescribed edoxaban in Belgium and the Netherlands: insights from the ETNA-AF-Europe study.

BACKGROUND: Studies on the use of non-vitamin K antagonist oral anticoagulants in unselected patients with atrial fibrillation (AF) show that clinical characteristics and dosing practices differ per region, but lack data on edoxaban. METHODS: With data from Edoxaban Treatment in routiNe clinical prActice for patients with AF in Europe (ETNA-AF-Europe), a large prospective observational study, we compared clinical characteristics (including the dose reduction criteria for edoxaban: creatinine clearance 15-50 ml/min, weight ≤60 kg, and/or use of strong p­glycoprotein inhibitors) of patients from Belgium and the Netherlands (BeNe) with those from other European countries (OEC). RESULTS: Of all 13,639 patients in ETNA-AF-Europe, 2579 were from BeNe. BeNe patients were younger than OEC patients (mean age: 72.3 vs 73.9 years), and had lower CHA2DS2-VASc (mean: 2.8 vs 3.2) and HAS-BLED scores (mean: 2.4 vs 2.6). Patients from BeNe less often had hypertension (61.6% vs 80.4%), and/or diabetes mellitus (17.3% vs 23.1%) than patients from OEC. Moreover, relatively fewer patients in BeNe were prescribed the reduced dose of 30 mg edoxaban (14.8%) than in OEC (25.4%). Overall, edoxaban was dosed according to label in 83.1% of patients. Yet, 30 mg edoxaban was prescribed in the absence of any dose reduction criteria in 36.9% of 30 mg users (5.5% of all patients) in BeNe compared with 35.5% (9.0% of all patients) in OEC. CONCLUSION: There were several notable differences between BeNe and OEC regarding clinical characteristics and dosing practices in patients prescribed edoxaban, which are relevant for the local implementation of dose evaluation and optimisation. TRIAL REGISTRATION: NCT02944019; Date of registration 24 October 2016.

Details are provided concerning the results of phase 3 clinical trials conducted to evaluate the efficacy and safety of two potential disease-modifying treatments for relapsing-remitting multiple sclerosis: ponesimod and ofatumumab. For the progressive forms, both available disease modifying treatments and others still in the research phase are reviewed. In the field of stem cell therapies, the article includes the results of the only clinical trial carried out to date comparing patients with relapsing-remitting multiple sclerosis treated with autologous haematopoietic stem cell transplantation and those treated with disease-modifying therapies. There are no important developments as regards symptomatic treatments, although the European Academy of Neurology has published a guide on palliative care. The various sources of information that collect pharmacovigilance data in the post-marketing setting are reviewed. CONCLUSIONS: Patients diagnosed in recent years tend to have less severe multiple sclerosis, probably due to the fact that it is diagnosed in its milder stages together with the steady increase in the number of treatments available.

[12th Post-ECTRIMS Meeting: review of the novelties from the 2019 ECTRIMS Congress (I)]. / XII Reunión Post-ECTRIMS: revisión de las novedades presentadas en el Congreso ECTRIMS 2019 (I).

INTRODUCTION: Like every year, after the ECTRIMS Congress, renowned Spanish neurologists who are experts in multiple sclerosis presented the main novelties in research in this field at the Post-ECTRIMS Meeting. AIM: To summarise the content presented at the 12th edition of the Post-ECTRIMS Meeting, which took place in September 2019 in Sevilla and is presented in two parts. DEVELOPMENT: This first part addresses the latest studies on vitamin D deficiency and the discrepancies that currently exist regarding its treatment. The advances made in epigenetics allow us to present this approach as a possible biomarker of multiple sclerosis. An account is provided to explain the growing importance of imaging techniques to detect atrophy and other phenomena that occur during the disease, such as changes in iron concentration or remyelination processes, which allow us to further our understanding of the mechanisms of cortical pathology, and the dimensionality of neurodegeneration during its course. Findings related to immunological mechanisms and advances in potential antigen-specific therapies are discussed. The contribution presents the latest studies on the assessment of cognitive impairment and its rehabilitation, which are becoming increasingly important due to the high prevalence of these disorders and the absence of their systematic assessment in clinical practice. Finally, the unmet social and health needs of multiple sclerosis patients in our country are presented, with emphasis on the current deficits in the system of social protection.

Objetivo. Sintetizar el contenido presentado en la XII edición de la Reunión Post-ECTRIMS, que tuvo lugar en septiembre de 2019 en Sevilla y que se presenta en dos partes. Desarrollo. Esta primera parte aborda los últimos estudios sobre el déficit de vitamina D y las discrepancias existentes acerca de su tratamiento. Los avances en epigenética realizados permiten presentar esta aproximación como un posible biomarcador de la esclerosis múltiple. Se explica el creciente protagonismo de las técnicas de imagen para detectar la atrofia y otros fenómenos que acontecen durante la enfermedad, como los cambios en la concentración de hierro o los procesos de remielinización, que nos permiten ganar comprensión sobre los mecanismos de la patología cortical, y sobre la dimensionalidad de la neurodegeneración durante su evolución. Se discuten los hallazgos relacionados con los mecanismos inmunológicos y los avances realizados en las potenciales terapias específicas del antígeno. Se presentan los últimos estudios sobre la evaluación del deterioro cognitivo y su rehabilitación, que cobran cada vez más importancia por la alta prevalencia de estas alteraciones y por la ausencia de su evaluación sistemática en la práctica clínica. Por último, se exponen las necesidades sociosanitarias no cubiertas de los pacientes de esclerosis múltiple en nuestro país, poniendo el acento en los déficits actuales del sistema de protección social.

Review of the novelties presented at the 2018 ECTRIMS Congress: 11th Post-ECTRIMS Meeting (II). / Revision de las novedades presentadas en el Congreso ECTRIMS 2018: XI Reunion Post-ECTRIMS (II).

The Post-ECTRIMS Meeting was held for the eleventh consecutive year in October 2018 in Madrid, with the aim of analysing the advances made in multiple sclerosis that were highlighted at the latest ECTRIMS annual congress. Based on the issues discussed at this meeting, attended by the nation's foremost opinion leaders on multiple sclerosis, two review articles are presented. This second part includes the growing body of evidence confirming the safety of exposure to disease-modifying treatments in women planning a pregnancy, and the beneficial effect of breastfeeding, provided that the disease is not very active. It addresses data showing how the application of the 2017 McDonald criteria in the paediatric population has significantly improved diagnosis compared to the previous criteria. With regard to progressive multiple sclerosis, the results of neuroprotective drugs are inconclusive, but biomarkers are proposed to improve the evaluation of the therapeutic response. Studies on myelin repair treatments suggest that remyelination in multiple sclerosis is possible. Likewise, there are favourable indications for haematopoietic stem cell transplantation, provided that patients are selected appropriately. On the other hand, we also conduct a review of the similarities and differences of the recommendations in the new clinical practice guidelines. Finally, the positive results of cognitive and motor rehabilitation with the use of new technologies point to the systematic incorporation of these tools in the treatment of the disease in the near future.

TITLE: Revision de las novedades presentadas en el Congreso ECTRIMS 2018: XI Reunion Post-ECTRIMS (II).La reunion Post-ECTRIMS se celebro por undecimo año consecutivo el pasado octubre de 2018 en Madrid, con el objetivo de analizar los avances en esclerosis multiple destacados en el ultimo congreso anual ECTRIMS. Fruto de esta reunion, formada por los lideres de opinion en esclerosis multiple de ambito nacional, se presentan dos articulos de revision. En esta segunda parte, se incluye el creciente numero de evidencias que confirman la seguridad de la exposicion a los tratamientos modificadores de la enfermedad en mujeres que planifican un embarazo, y el efecto beneficioso de la lactancia, siempre y cuando la enfermedad no este muy activa. Se abordan los datos que muestran como la aplicacion de los criterios de McDonald de 2017 en poblacion pediatrica ha mejorado considerablemente el diagnostico en comparacion con los criterios anteriores. En cuanto a la esclerosis multiple progresiva, los resultados de los farmacos neuroprotectores son poco concluyentes, pero se proponen biomarcadores para mejorar la evaluacion de la respuesta terapeutica. Los estudios sobre tratamientos de reparacion de la mielina sugieren que la remielinizacion en la esclerosis multiple es posible. De igual manera, se exponen indicios favorables sobre el trasplante de celulas madre hematopoyeticas, siempre que se seleccione adecuadamente a los pacientes. Por otro lado, se revisan las similitudes y diferencias de las recomendaciones de las nuevas guias de practica clinica publicadas. Por ultimo, los resultados positivos de la rehabilitacion cognitiva y motora con el uso de las nuevas tecnologias vaticinan la incorporacion sistematica de estas herramientas en el tratamiento de la enfermedad en un futuro proximo.

[Review of the novelties presented at the 2018 ECTRIMS Congress: 11th Post-ECTRIMS Meeting (I)]. / Revision de las novedades presentadas en el congreso ECTRIMS 2018: XI Reunion Post-ECTRIMS (I).

The Post-ECTRIMS Meeting is an emblematic event in Spain which seeks to review and disseminate the main advances in multiple sclerosis presented at the ECTRIMS annual congress. In October 2018, the eleventh Post-ECTRIMS meeting was held in Madrid and was attended by the country's leading experts in multiple sclerosis. As a result of this meeting, we present two articles which outline the most interesting novelties discussed there. This first part includes the latest results obtained regarding the influence of modifiable and non-modifiable risk factors in multiple sclerosis, with emphasis on the progress made in the field of genetics, where the discovery of genes associated with multiple sclerosis has increased exponentially. The complexity of the immune system is addressed and some contributions are made on autoimmunity mechanisms, in which bidirectional relations are observed between immune cells and cells residing in the central nervous system, such as microglial cells and astrocytes. Biomarkers, both in serum and cerebrospinal fluid as well as in imaging, are gaining more and more attention due to their current and, above all, potential role in the diagnosis and prognosis of the disease and in the evaluation of the efficacy of treatments. Finally, the observations made regarding changes in structural and functional connectivity in patients and their relationship with clinical alterations are presented.

En octubre de 2018, la reunion Post-ECTRIMS celebro en Madrid su undecima edicion, contando con los mayores expertos de ambito nacional en esclerosis multiple. Como resultado de esta reunion, se presentan dos articulos donde se recogen las novedades mas destacadas en la misma. En esta primera parte se incluyen los ultimos resultados sobre la influencia de los factores de riesgo modificables y no modificables en la esclerosis multiple, destacando los progresos realizados en el ambito genetico, donde el descubrimiento de genes asociados a la esclerosis multiple ha aumentado exponencialmente. Se aborda la complejidad del sistema inmune y se realizan algunas aportaciones sobre los mecanismos de autoinmunidad, en los que se observan relaciones bidireccionales entre las celulas inmunes y las celulas residentes del sistema nervioso central, como la microglia y los astrocitos. Los biomarcadores, tanto en suero y liquido cefalorraquideo como de imagen, ganan cada vez mas atencion por su papel actual, y sobre todo potencial, en el diagnostico y pronostico de la enfermedad y en la evaluacion de la eficacia de los tratamientos. Por ultimo, se presentan las observaciones realizadas respecto a los cambios en la conectividad estructural y funcional en los pacientes y su relacion con las alteraciones clinicas.

Persistent but reversible advanced atrio-ventricular block in a heart transplant man induced by dobutamine stress echocardiography.

Dobutamine when used for stress echocardiography (DSE), it rarely causes transient atrio-ventricular (AV) block. We report a heart transplant patient with high cardiovascular risk who developed symptomatic advanced AV block during DSE which persisted after termination of dobutamine administration, necessitating pacemaker implantation. To our knowledge, this is the first published case of persistent high grade AV block in a heart transplant patient induced by DSE.

[Review of the novelties from the 2017 ECTRIMS Congress, presented at the 10th Post-ECTRIMS Meeting (II)]. / Revision de las novedades del Congreso ECTRIMS 2017, presentadas en la X Reunion Post-ECTRIMS (II).

The Post-ECTRIMS Meeting is an emblematic event in the field of multiple sclerosis in Spain. Its chief aim is bring together the country's leading specialist neurologists to analyse the main advances made in multiple sclerosis and to review the most important topics addressed at the ECTRIMS Congress. The tenth Post-ECTRIMS Meeting was held in November 2017. Over the years this event has firmly established itself as an important meeting point where experts from all over the country get together to foster communication, establish synergies and promote and enhance research ultimately aimed at improving the prognosis and quality of life of patients with multiple sclerosis. This second part addresses the different strategies for the management of patients in advanced stages of the disease and the safety of therapy in multiple sclerosis. Likewise, attention is also drawn to the areas that require further scientific and clinical evidence. In this edition, particular importance is given to multiple sclerosis in the paediatric population and ageing in the disease. At the same time emphasis is placed on the need to conduct collaborative studies and to foster greater awareness among specialists regarding the detection and management of the comorbidities in multiple sclerosis.
