Antecedents: Hi ha escassa informació disponible sobre l’atròfia cerebral global i de substància gris i blanca (SG i SB) en l'esclerosi múltiple primària progressiva (EMPP) i en la seva relació amb paràmetres clínics i de ressonància magnètica (RM); per altra banda, les anomalies en el teixit cerebral d’aparença normal poden contribuir a la discapacitat. Objectiu: Avaluar els mecanismes subjacents a la progressió de la malaltia en les primeres fases de l'EMPP emprant eines de volumetria cerebral i calculant les concentracions de metabòlits mitjançant la imatge de RM per espectroscòpica de protons (IRME) a l'inici de l'estudi i després d'un any de seguiment, i avaluant la seva relació amb els paràmetres clínics i radiològics convencionals. Mètodes: Quaranta-tres pacients amb EMPP dins dels 5 anys primers anys de malaltia i 45 subjectes sans s’inclogueren a l'inici de l'estudi per a l’anàlisi volumètric; després d'un any 31 pacients tingueren un segon examen de RM volumètrica; per als estudis d’IRME, hi havia 41 pacients amb EMPP i 44 subjectes sans disponibles a l'inici de l'estudi i després d'un any es disposava de 21 parells d’estudis (basal – 12 mesos) de pacients amb vòxels de SG cortical i 24 parells d’estudis de pacients amb vòxels de substància blanca d’aparença normal (SBAN) utilitzables. Per als estudis d'atròfia, es va adquirir una seqüència 3D inversion-prepared fast spoiled gradient recall (3DFSPGR); les dades d’IRME es varen adquirir d’un volum situat immediatament superior al sostre dels ventricles laterals emprant una seqüencia point resolved spectroscopy (PRESS). Els anàlisis volumètrics es van realitzar emprant els programes SPM99 (Statistical Parametric Mapping 99) i SIENA (Structural Imaging Evaluation, using Normalization, of Atrophy). Les imatges cerebrals varen ser segmentades en SB, SG, i líquid cefaloraquidi, calculant-se els valors de les fraccions de parènquima cerebral total (FPC), SB (FSB), i SG (FSG). Utilitzant SIENA es va obtenir el percentatge de canvi de volum cerebral (PBVC). Les concentracions de colina (Cho), fosfocreatina (Cr), myo-inositol (Ins), N-acetil-aspartat total (tNAA), i glutamat-glutamina (Glx) es van estimar a través del programari Linear Combination Model (LCModel). Es varen determinar els volums de lesió en seqüències ponderades en T2 i en T1 que realçaven amb gadolini. Es varen obtenir les puntuacions en les escales Expanded Disability Status Scale (EDSS) i Multiple Sclerosis Functional Composite (MSFC) per a cada pacient. Les anàlisis estadístiques es varen realitzar utilitzant les proves apropiades en cada moment per tal d’investigar l'associació entre els paràmetres volumètrics i metabòlics i els corresponents a les valoracions clíniques i de RM convencional, i per avaluar el canvi en aquests paràmetres després d'un any. Resultats i conclusions: S’ha observat pèrdua de volum cerebral global, que afecta tant la FSG com la FSB, als pacients amb EMPP a l'inici de la malaltia per damunt el que s’observa en una mostra de controls sans. Tant la FSG com la FSB s’associen als paràmetres clínico-radiològics convencionals. S’observen disminucions significatives en FPC i FSG al cap de l’any, però no en FSB. Els canvis en FSB es poden predir per la quantitat d'inflamació visible per RM a l'inici de l'estudi, mentre que els canvis en FSG no es poden predir per cap paràmetre. A la SG cortical, les concentracions de tNAA i Glx són més baixes en pacients que en controls. A la SBAN, el tNAA s'ha trobat reduït (encara que en menor mesura) i l’Ins elevat en pacients en comparació amb controls. A la SG cortical el tNAA i a la SBAN l’INS s'han trobat associats amb els paràmetres clínics i radiològics. No s'han detectat canvis significatius de concentració de cap dels metabòlits a cap teixit al cap d’un any., Background: There is little information available on global and on grey and white matter (GM and WM) atrophy in primary progressive multiple sclerosis (PPMS) and on their relationship with clinical and with other magnetic resonance imaging (MRI) measures; on the other hand abnormalities in normal-appearing brain tissues may contribute to disability in PPMS, where fewer lesions are seen on conventional imaging. Aim: To evaluate the mechanisms underlying disease progression in the early phase of PPMS, focusing on axonal loss as assessed by volumetric MRI measures of WM and GM, and by measuring metabolite concentrations in normal-appearing white matter (NAWM) and cortical GM using proton magnetic resonance spectroscopic imaging (MRSI) at baseline and after one year of follow-up and to assess their relationship with clinical outcomes. Methods: Forty-three patients with PPMS within 5 years of symptom onset and 45 control subjects were included at baseline for the volumetric study; after one year 31 patients returned for a second volumetric MRI examination; for the MRSI examinations 41 patients with PPMS and 44 control subjects were available at baseline (final availability of usable voxels vary according to tissue and group) and 21 pairs of patients yielded usable cortical GM voxels and 24 patients yielded usable NAWM voxels after one year. For atrophy studies, a 3D inversion-prepared fast spoiled gradient recall (3DFSPGR) sequence was acquired; for spectroscopy studies, MRSI data were acquired from a volume located superior to the roof of the lateral ventricles using a point resolved spectroscopy (PRESS) localization sequence. Volumetric analyses were performed at baseline and follow-up using SPM99 (Statistical Parametric Mapping 99) and SIENA (Structural Imaging Evaluation, using Normalization, of Atrophy) software; brain scans were segmented into WM, GM, and cerebrospinal fluid, and brain parenchymal (BPF), WM (WMF), and GM fractions (GMF) normalized against total intracranial volumes were estimated. Using SIENA the percentage brain volume change (PBVC) over one year was obtained. Concentrations of choline-containing compounds (Cho), phosphocreatine (Cr), myo-inositol (Ins), total N-acetyl-aspartate (tNAA), and glutamate-glutamine (Glx) were estimated using proton MRSI using the Linear Combination Model (LCModel) software. T2-weighted and T1-weighted gadolinium-enhancing lesion volumes were also determined. Expanded Disability Status Scale (EDSS) and Multiple Sclerosis Functional Composite (MSFC) scores were recorded in all patients. Statistical analyses were performed using appropriate tests to investigate the association between volumetric and metabolic parameters with those obtained from clinical and conventional MRI assessments, and to evaluate change in these parameters after one year. Results & conclusions: Brain atrophy, affecting both GMF and WMF, has been found to be present early in the course of PPMS exceeding what is observed in a sample of healthy controls after adjusting for significant variables. Both GMF and WMF are related to clinical and MRI lesion-related parameters. Significant decreases in BPF and GMF can be observed after one year, but cannot be detected in the WMF. WMF changes can be predicted by the amount of MRI-visible inflammation at baseline, whereas GMF changes cannot be predicted by any clinical or MRI parameter investigated. In cortical GM, concentrations of tNAA and Glx have been found to be lower in patients as compared to control subjects. In NAWM, tNAA has also been found to be reduced (although to a lower extent) and Ins to be increased in patients as compared to control subjects. In cortical GM tNAA and, in NAWM, Ins levels have been found to correlate with clinical parameters. No changes have been detected in either cortical GM or NAWM for any of the metabolite concentrations after one year of follow-up.

BRAIN stimulation ,NEUROPLASTICITY ,SENSORY conflict ,TRANSCRANIAL direct current stimulation ,CENTRAL nervous system ,REHABILITATION - Abstract
Although the number of disease-modifying treatments for people with multiple sclerosis (pwMS) has meaningfully increased in the past years, targeting repair or compensation for central nervous system damage associated with the disease process remains an important clinical goal. With this aim, neurorehabilitation is a powerful approach targeting central nervous system plasticity. Another driver of brain plasticity is non-invasive brain stimulation (NIBS), receiving recent attention in neurology, particularly for its potential synergy with neurorehabilitation and as add-on treatment for several neurological conditions, from pain to fatigue to sensorimotor and cognitive deficits. In this review, we will resume the evidence exploring the neurobiological basis of NIBS and its applications to MS-related conditions. [ABSTRACT FROM AUTHOR]

REHABILITATION ,MULTIPLE sclerosis ,CLINICAL trials - Abstract
Rehabilitation is an essential aspect of symptomatic and supportive treatment for people with multiple sclerosis (MS). The number of randomised controlled trials (RCTs) for rehabilitation interventions in MS has increased over the last two decades. The design, conduct and reporting quality of some of these trials could be improved. There are, however, some specific challenges that researchers face in conducting RCTs of rehabilitation interventions, which are often 'complex interventions'. This paper explores some of the challenges of undertaking robust clinical trials in rehabilitation. We focus on issues related to (1) participant selection and sample size, (2) interventions – the 'dose', content, active ingredients, targeting, fidelity of delivery and treatment adherence, (3) control groups and (4) outcomes – choosing the right type, number, timing of outcomes, and the importance of defining a primary outcome and clinically important difference between groups. We believe that by following internationally accepted RCT guidelines, by developing a critical mass of MS rehabilitation 'trialists' through international collaboration and by continuing to critique, challenge, and develop RCT designs, we can exploit the potential of RCTs to answer important questions related to the effectiveness of rehabilitation interventions.

TREATMENT programs ,REHABILITATION ,DECISION making ,LEARNING goals ,CONSTRUCTION planning - Abstract
Shared decision-making occurs when the decision is 'preference sensitive'. It consists of identifying the different treatment options (choice talk), considering the advantages and disadvantages of each option (option talk), and then supporting making the decision in the light of an individual's experiences and values (decision talk). It is most effective when working with an 'activated patient', that is, one who is prepared for the shared decision-making role. In rehabilitation, many decisions are preference sensitive. These decisions may be framed as 'goal setting'. Skilled clinicians can support patients to learn goal setting skills until the person has the skills to maintain health supporting behaviours most of the time, only seeing a clinical team at times of change or crisis. The steps in goal setting can be summarised as building empathy, creating a contract, identifying priorities, summarising the conversation, articulating the goal, defining actions, building coping plans, and then reviewing progress. Working with people with MS can extend beyond working with individuals to a consideration of what people with MS want from services. This can result in the co-production and co-design of services, as well as the identification of research priorities as exemplified by the James Lind Alliance. [ABSTRACT FROM AUTHOR]

BEHAVIOR ,BEHAVIOR therapy ,CLINICAL trials - Abstract
A critical aspect of many rehabilitation interventions for people with multiple sclerosis (MS) is incorporating strategies that support behavior change. The main purpose of this topical review was to summarize recent randomized clinical trials (RCTs) of rehabilitation interventions in which participants learn and apply skills or engage in healthy behaviors. The Capability, Opportunity, Motivation, and Behavior (COM-B) framework was used to broadly classify behavior-change strategies. The included RCTs varied widely in terms of dosing, delivery format, and types of interventionist. Commonly used behavior-change strategies include education, persuasion, and training. We recommend that researchers and clinicians use frameworks like Behavior Change Wheel and Behavior Change Technique Taxonomy to describe and classify intervention strategies used to promote behavior change. We also recommend more sophisticated RCTs be conducted (e.g. sequential multiple assignment randomized trial and three-arm RCTs) to better understand ways of promoting behavior change in rehabilitation interventions.

NEUROPSYCHOLOGICAL tests ,MULTIPLE sclerosis ,TEST validity ,ACTIVITIES of daily living - Abstract
In neurological diseases such as multiple sclerosis (MS), a neuropsychological assessment is often requested to assist clinicians in evaluating the role of cognition in a patient's level of everyday functioning. To be effective in this charge, it is assumed that performance on neuropsychological tests is related to how a person may function in everyday life, and the question is often asked: "Are neuropsychological tests ecologically valid?" In this review, we synthesize the literature that examines the use of neuropsychological tests to assess functioning across a variety of everyday functioning domains in MS (i.e. driving, employment, instrumental activities of daily living (IADLs)). However, we critically examine the usefulness of asking this broad question regarding ecological validity, given the psychometric and conceptual pitfalls it may yield. While many neuropsychological tests may be generally considered "ecologically valid" in MS, it is much more helpful to specify for whom, under what circumstances, and to what degree.

MULTIPLE sclerosis ,WEIGHT loss ,BRAIN ,REHABILITATION ,PREVENTION - Abstract
Persons with multiple sclerosis (MS) experience cognitive and physical decline despite more effective disease-modifying therapies (DMTs), and symptomatic treatments currently have limited efficacy. The best treatment of MS disability may, therefore, be prevention of decline. Here, we present a working model of reserve and brain maintenance, with a focus on modifiable risk and protective factors. At disease onset, patients have varying degrees of reserve, broadly conceptualized as the dynamic availability of cerebral resources to support functional capacity. A clinical focus on prevention aims to minimize factors that deplete reserve (e.g. disease burden, comorbidities) and maximize factors that preserve reserve (e.g. DMTs, cardiovascular health). We review evidence for cardiovascular health, diet, and sleep as three potentially important modifiable factors that may modulate cerebral reserve generally, but also in disease-specific ways. We frame the brain as a limited capacity system in which inefficient usage of available cerebral capacity (reserve) leads to or exacerbates functional deficits, and we provide examples of factors that may lead to such inefficiency (e.g. poor mood, obesity, cognitive-motor dual-tasking). Finally, we discuss the challenges and responsibilities of MS neurologists and patients in pursuing comprehensive brain maintenance as a preventive approach. [ABSTRACT FROM AUTHOR]

WEARABLE technology ,NEUROLOGICAL disorders ,MULTIPLE sclerosis ,DISEASE management - Abstract
Wearable sensors are designed to be worn on the body or embedded into portable devices (e.g. smartphones and smartwatches), allowing continuous patient-based monitoring, objective outcomes measuring, and feedback delivering on daily-life activities. Within the medicine domain, there has been a rapid increase in the development, testing, and use of wearable technologies especially in the context of neurological diseases. Although wearables represent promising tools also in multiple sclerosis (MS), the research on their application in MS is still ongoing, and further studies are required to assess their reliability and accuracy to monitor body functions and disability in people with MS (pwMS). Here, we provided a comprehensive overview of the opportunities, potential challenges, and limitations of the wearable technology use in MS. In particular, we classified previous findings within this field into macro-categories, considered crucial for disease management: assessment, monitoring, intervention, advice, and education. Given the increasing pivotal role played by wearables, current literature suggests that for pwMS, the time is right to shift from a center-based traditional therapeutic paradigm toward a personalized patient-based disease self-management. On this way, we present two ongoing initiatives aimed at implementing a continuous monitoring of pwMS and, consequently, providing timely and appropriate care interventions. [ABSTRACT FROM AUTHOR]

In the last decade, rehabilitation technology has been developed, investigated, and entered specialized clinical settings. In this chapter, we first discuss the potential of rehabilitation technology to support the achievement of key factors in motor recovery, such as delivering massed practice with good movement quality but also question task-specificity and cognitive motor control mechanisms. Second, we discuss available technology-supported rehabilitation methods for improving gait, balance and fitness, and upper limb function. Finally, we discuss considerations in relation to the professional workforce in order to deliver optimal rehabilitation. [ABSTRACT FROM AUTHOR]

Background: Neural plasticity represents the substrate by which the damaged central nervous system (CNS) re-learns lost behaviors in response to rehabilitation. In persons with multiple sclerosis (MS), rehabilitation can therefore exploit the potential of neural plasticity to restore CNS functions beyond the spontaneous mechanisms of recovery from MS-related damage. Methods: Here, we reviewed the currently available evidence on the occurrence of mechanisms of structural and functional plasticity following rehabilitation, motor, and/or cognitive training. We presented both data gained from basic laboratory research on animal models and data on persons with MS obtained by advanced magnetic resonance imaging (MRI) techniques. Results: Studies on physical and environmental enrichment in experimental MS models showed beneficial effects mediated by both immune modulation and activity-dependent plasticity, lowering tissue destruction and restoring of CNS network function. Translational researches in MS people demonstrated structural and/or functional MRI changes after various interventions, but their heterogeneity and small sample sizes (5–42 patients) raise concerns about the interpretation and generalization of the obtained results. Discussion: We highlighted the limitations of published studies, focusing on the knowledge gaps to be filled in terms of neuropathological correlations between changes detected in animal models and changes detected in vivo by neuroimaging.

Purpose: Brain volume estimates from magnetic resonance images (MRIs) are of great interest in multiple sclerosis, and several automated tools have been developed for this purpose. The goal of this study was to assess the agreement between two tools, NeuroQuant® (NQ) and FMRIB's Integrated Registration Segmentation Tool (FIRST), for estimating overall and regional brain volume in a cohort of patients with a clinically isolated syndrome (CIS). In addition, white matter lesion volume was estimated with NQ and the Lesion Segmentation Toolbox (LST). Methods: One hundred fifteen CIS patients were analysed. Structural images were acquired on a 3.0-T system. The volume agreement between methods (by estimation of the intraclass correlation coefficient) was calculated for the right and left thalamus, caudate, putamen, pallidum, hippocampus, and amygdala, as well as for the total intracranial volume and white matter lesion volume. Results: In general, the estimated volumes were larger by NQ than FIRST, except for the pallidum. Agreement was low (ICC < 0.40) for the smaller structures (amygdala and pallidum) and fair to good (ICC > 0.40) for the remaining ones. Agreement was fair for lesion volume (ICC = 0.61), with NQ estimates lower than LST. Conclusions: Agreement between NQ and FIRST brain volume estimates depends on the size of the structure of interest, with larger volumes achieving better agreement. In addition, concordance between the two tools does seem to be dependent on the presence of brain lesions. [ABSTRACT FROM AUTHOR]

- Abstract
Optic neuritis is a common feature in multiple sclerosis (MS) and in two other autoimmune demyelinating disorders such as Aquaporin-4 IgG (AQP4-IgG) antibody-associated neuromyelitis optica spectrum disorder (NMOSD) and myelin-oligodendrocyte glycoprotein antibody-associated disease (MOGAD). Although serological testing is critical for differentiating these different autoimmune-mediated disorders, magnetic resonance imaging (MRI), which is the preferred imaging modality for assessing the optic nerve, can provide valuable information, suggesting a specific diagnosis and guiding the appropriate serological testing.

- Abstract
La esclerosis múltiple (EM) es una enfermedad inflamatoria desmielinizante del sistema nervioso central. Su evolución es muy variable entre individuos, como también lo es la respuesta de éstos al tratamiento. Las medidas clínicas de actividad son solo parcialmente útiles para predecir los cambios en la evolución de la enfermedad. Además, la resonancia magnética (RM), aunque altamente sensible para detectar lesiones, presenta solo una moderada correlación con la evolución de la discapacidad. El daño neuroaxonal sobre las lesiones como en el tejido cerebral aparentemente normal es probablemente la causa subyacente de discapacidad permanente. Las medidas de atrofia cerebral mediante RM reflejan la pérdida tisular y es posible obtenerlas actualmente mediante programas informáticos de procesamiento de imagen. No obstante, el papel de la atrofia como biomarcador pronóstico en EM es poco conocido, por lo que se planteó investigar su valor en situaciones de práctica clínica habitual, como son la predicción del riesgo de conversión a EM clínicamente definida (EMCD) tras un síndrome clínico aislado (SCA) y la predicción de progresión de la discapacidad a pesar de iniciar terapia modificadora de la evolución de la enfermedad (TME). Para ello, se analizaron los exámenes de RM de dos cohortes prospectivas: 1)cohorte SCA, compuesta de 176 pacientes con un SCA, en los que se realizó un examen de RM convencional a los 3 meses del inicio de los síntomas y al año y que fueron seguidos un mínimo de 2 años; 2)cohorte TME, compuesta de 105 pacientes con EMCD que iniciaron TME con interferón β (IFNβ), en los que se realizó un examen de RM convencional previamente al inicio de IFNβ y al año, y que fueron seguidos ≥2 años y hasta completar 4 años. Los análisis volumétricos se realizaron mediante los programas SIENA (Structural Imaging Evaluation, using Normalization, of Atrophy) para el cálculo del porcentaje de cambio del volumen cerebral (PCVC) y SPM (Statistical Parametric Mapping) para, Multiple sclerosis (MS) is an inflammatory demyelinating disease of the central nervous system. Its evolution varies widely among individuals, and so is their response to treatment. Measures of MS clinical activity are only partially useful to predict changes in the evolution of the disease. On the other hand, magnetic resonance imaging (MRI), although highly sensitive to detect lesions, only has a moderate correlation with the evolution of disability. The axonal damage in both lesions and normal-appearing white matter is probably the underlying cause of permanent disability. The measures of brain atrophy by MRI reflect tissue loss and it is possible to obtain them nowadays, using softwares for image processing. However, there is little information on the clinical relevance of atrophy as a prognostic biomarker in MS, so we set out to investigate whether the measurement of brain atrophy can be useful in routine clinical practice situations, such as predicting the risk of conversion to clinically definite MS (CDMS) after a clinically isolated syndrome (CIS) and the prediction of disability progression after starting disease-modifying drugs (DMD). For this purpose, the images from the MRI scans of two prospectively followed cohorts of patients were analyzed: 1) CIS cohort, composed of 176 patients with CIS, in which conventional MRI scans were performed at 3 months of the onset of symptoms and one year after, and that were followed up at least 2 years; 2) DMD cohort, composed of 105 CDMS patients who started their first immunomodulatory therapy with interferon β (IFNβ), in which conventional MRI scans were performed prior to starting IFNβ therapy and one year after, and that were followed up a minimum of 2 years and up to 4 years. Volumetric analyses were performed using SIENA (Structural Imaging Evaluation, using Normalization, of Atrophy) software for determining the percentage brain volume change (PBVC), and SPM (Statistical Parametric Mapping) software for calculat

- Abstract
Premi Extraordinari de Doctorat concedit pels programes de doctorat de la UAB per curs acadèmic 2017-2018, La esclerosis múltiple (EM) es una enfermedad crónica, inmunomediada y degenerativa que afecta principalmente a adulto jóvenes, siendo la segunda causa de discapacidad neurológica en esas edades. De forma temprana, los pacientes con EM presentan una pérdida de volumen cerebral (VC) que se ha relacionado con el grado de discapacidad concurrente así como con el que ocurrirá durante el seguimiento. La mayoría de los tratamientos aprobados hoy en día para el manejo de la enfermedad, han demostrado poseer un efecto beneficioso sobre la pérdida de VC. Sin embargo, en algunos casos no se han podido demostrar diferencias significativas, especialmente durante los primeros meses tras el inicio del tratamiento. En este sentido, es importante tener en cuenta que la presencia de inflamación debida a la enfermedad, tiene un impacto sobre la medida de VC. Los pacientes que inician un tratamiento, ya sea en contexto de un ensayo clínico o en la práctica clínica habitual, suelen ser pacientes con importante actividad clínica (en forma de brotes) y radiológica (con lesiones que realzan tras la administración de gadolinio en la RM cerebral). La resolución de esta inflamación dará lugar una pérdida de VC inicial más acelerada durante los primeros meses de tratamiento; este fenómeno se ha descrito como el efecto de pseudoatrofia. Este proyecto de tesis doctoral se centra en el estudio y conocimiento del efecto de pseudoatrofia cerebral en los pacientes que inician tratamiento con natalizumab e interferón beta, con el objetivo último de comprender mejor la dinámica del cambio de VC en estas circunstancias y poder ofrecer mejores herramientas de monitorización clínica y radiológica a nuestros pacientes. La principal hipótesis de trabajo de la tesis doctoral fue que el cambio de VC que ocurre durante el primer año de tratamiento con natalizumab e interferón beta se relacionará con la presencia de actividad inflamatoria basal o pre-tratamiento. Además, el cambio de volumen cerebral observad, Multiple sclerosis (MS) is a chronic, immune-mediated and degenerative disease that primarily affects young adults. It is the second cause of neurological disability in this age group. Brain volume (BV) loss is known to occur since very early stages of the disease and it has been related to relevant clinical outcomes such as neurological disability. Most of the treatments currently approved for the management of the disease, have demonstrated a beneficial effect on BV loss. However, in some cases significant differences could have not been demonstrated, especially during the first few months after treatment onset. In this regard, it is important to note that the presence of inflammation due to the disease could have an impact on the extent of BV loss. Patients starting treatment usually present with significant clinical (relapses) and radiological (gadolinium-enhancing lesions) disease activity. The resolution of this inflammation will result in a more rapid loss of initial BV during the first months of treatment; this phenomenon has been described as the pseudoatrophy effect. This doctoral thesis focuses on the study and knowledge of the pseudoatrophy effect in patients starting treatment with natalizumab and interferon beta, in order to better understand the dynamics of BV loss in these circumstances and to offer better tools for monitoring our patients. The main hypothesis was that the BV loss occurring during the first year of treatment with natalizumab and interferon beta would relate with baseline inflammatory disease activity. In addition, BV loss occurring during the first year of treatment with natalizumab and interferon beta, will affect differently grey and white matter, especially in patients with baseline inflammatory disease activity. With these assumptions we studied two cohorts of patients who started treatment in our centre and that had amenable brain magnetic resonance imaging (MRI) at baseline and one year after treatment onset with natalizumab an

- Abstract
© 2016 Springer-Verlag Berlin Heidelberg Introduction: Regional brain volume estimation in multiple sclerosis (MS) patients is prone to error due to white matter lesions being erroneously segmented as grey matter. The Lesion Segmentation Toolbox (LST) is an automatic tool that estimates a lesion mask based on 3D T2-FLAIR images and then uses this mask to fill the structural MRI image. The goal of this study was (1) to test the LST for estimating white matter lesion volume in a cohort of MS patients using 2D T2-FLAIR images, and (2) to evaluate the performance of the optimized LST on image segmentation and the impact on the calculated grey matter fraction (GMF). Methods: The study included 110 patients with a clinically isolated syndrome and 42 with a relapsing-remitting MS scanned on a 3.0-T MRI system. In a subset of consecutively selected patients, the lesion mask was semi-manually delineated over T2-FLAIR images. After establishing the optimized LST parameters, the corresponding regional fractions were calculated for the original, filled, and masked images. Results: A high agreement (intraclass correlation coefficient (ICC) = 0.955) was found between the (optimized) LST and the semi-manual lesion volume estimations. The GMF was significantly smaller when lesions were masked (mean difference -0.603, p < 0.001) or when the LST filling technique was used (mean difference -0.598, p < 0.001), compared to the GMF obtained from the original image. Conclusion: LST lesion volume calculation seems reliable. GMFs are significantly reduced when a method to correct the contribution of MS lesions is used, and it may have an impact in assessing GMF differences between clinical cohorts., Postprint (author's final draft)

- Abstract
Background and objectives: Treatment of spasticity poses a major challenge given the complex clinical presentation and variable efficacy and safety profiles of available drugs. We present a systematic review of the pharmacological treatment of spasticity in multiple sclerosis (MS) patients. Methods: Controlled trials and observational studies were identified. Scientific evidence was evaluated according to pre-specified levels of certainty. Results: The evidence supports the use of baclofen, tizanidine and gabapentin as first-line options. Diazepam or dantrolene could be considered if no clinical improvement is seen with the previous drugs. Nabiximols has a positive effect when used as add-on therapy in patients with poor response and/or tolerance to first-line oral treatments. Despite limited evidence, intrathecal baclofen and intrathecal phenol show a positive effect in severe spasticity and suboptimal response to oral drugs. Conclusion: The available studies on spasticity treatment offer some insight to guide clinical practice but are of variable methodological quality. Large, well-designed trials are needed to confirm the effectiveness of antispasticity agents and to produce evidence-based treatment algorithms.

- Abstract
Els estudis epidemiològics d'Esclerosi Múltiple (EM) a nivell mundial mostren un augment generalitzat en la prevalença i un increment en la incidència, fonamentalment en les latituds més baixes, considerades inicialment zones de baix risc. Així, el sud d'Europa és una zona clau per a l'estudi de les tendències epidemiològiques actuals de l'EM. A Catalunya existia poca informació epidemiològica de l'EM. El gran impacte sanitari i socioeconòmic d'aquesta malaltia fa imprescindible conèixer la seva freqüència i distribució. En aquesta tesi doctoral es realitza una caracterització de l'epidemiologia de l'EM a Catalunya mitjançant l'estudi dels paràmetres epidemiològics descriptius més rellevants (incidència anual i prevalença). Per a l'estudi d'incidència es van incloure tots aquells pacients amb sospita d'EM entre l'1 de gener de 2009 i el 31 de desembre de 2009 que residissin a Catalunya en el moment d'inici de la simptomatologia. Cada pacient va ser seguit fins a la seva eventual confirmació del diagnòstic d'EM (criteris de McDonald 2005). Perquè la recollida de dades fos exhaustiva, i el projecte tingués viabilitat a llarg termini, s'ha iniciat el Registre d'Esclerosi Múltiple de Catalunya, de base poblacional, prospectiu i multicèntric. Al llarg dels 5 anys d'estudi (2009-2013) el registre ha comptat amb la participació de 44 hospitals de Catalunya que han notificat un total de 1003 pacients. Es va determinar la cobertura del registre mitjançant una anàlisi de captura-recaptura amb una font de dades independent, resultant: un 42% per a Catalunya (amb variabilitat segons províncies), un 90% a Girona i el 15% a Tarragona. Amb la intenció de minimitzar l'impacta de la possible infra-declaració de casos, el càlcul d'incidència es va limitar a la província de Girona. El Registre va incloure 183 pacients que van experimentar un primer brot a Girona entre gener de 2009 i desembre de 2013. Dels casos, 51 van iniciar els símptomes en 2009 resultant en una incidència de 3,6, Los estudios epidemiológicos de Esclerosis Múltiple (EM) a nivel mundial muestran un aumento generalizado en la prevalencia y un incremento en la incidencia, fundamentalmente en las latitudes más bajas, consideradas inicialmente zonas de bajo riesgo.

Therefore, southern Europe becomes a key area for the study of current epidemiological trends of MS. In Catalonia there is a lack of epidemiological data on MS and due to its health and economic impact, it is essential to know its frequency and distribution. This work involves the characterization of the epidemiology of MS in Catalonia by studying the most relevant descriptive epidemiological parameters (incidence and prevalence). The incidence study included all patients with suspected MS between January 1, 2009 and December 31, 2009 resident in Catalonia at the time of the onset of symptoms. Each patient was followed until the eventual diagnosis confirmation (McDonald criteria 2005). In order to performe an exhaustive data collection and make sure the project would have long-term viability, the population-based Multiple Sclerosis Registry of Catalonia was launched. Throughout five years of evaluation (2009-2013) 44 hospitals throughout Catalonia paricipated in the registry and reported a total of 1003 patients. The coverage was determined by a capture-recapture analysis with an independent source of data resulting in 42% for Catalonia, with variability by province (90% in Girona and 15% in Tarragona). In order to minimize the impact of the under-reporting, the calculation of incidence was narrowed to the province of Girona. The registry included 183 patients experiencing a first attack suggestive of MS in Girona from January 2009 to December 2013. Of these, 51 had the onset of symptoms in 2009 resulting in an incidence of 3.6 per 100,000 (95% CI: 2.4 - 5.3); 4.3 (95% CI 2.5 to 7.1) for women and 2.9 (95% CI: 1.4 to 5.2) for men. The adjusted incidence rate for the European population was 3.29 (95% CI: 3.2 to 3.3). The prevalence study was conducted in Osona, where a previo

Background: Brain atrophy in multiple sclerosis (MS) patients is present since the very early stages of the disease and it has been related to long-term disability. Objective: To estimate brain volume (BV) at 15 years after a clinically isolated syndrome (CIS) and to evaluate its relationship with disease outcomes. Methods: From a prospective cohort including patients presenting with a CIS, 54 patients with a brain magnetic resonance imaging (MRI) performed 15 years after CIS were included. Brain parenchymal fraction (BPF), grey matter fraction (GMF) and white matter fraction (WMF) at 15-year follow-up were obtained. Regression analyses were conducted to predict BV loss and reaching an Expanded Disability Status Scale (EDSS) of 3.0 in that 15-year period. Results: In multivariable analyses, lower values of BPF and WMF were significantly associated with being male, presenting 3–4 Barkhof criteria at baseline, presenting a second relapse, and with a decision to start treatment. In the multivariable logistic regression analysis, only lower GMF was associated with a greater risk of reaching EDSS 3.0 (odds ratio (OR) = 0.24, p = 0.028). Conclusion: Lower BPF and WMF 15 years after CIS are associated with previous markers of inflammatory disease. Lower GMF 15 years after a CIS is associated with an increased risk of reaching an EDSS of 3.0. [ABSTRACT FROM AUTHOR]

Background: The usefulness of performing a spinal cord (SC) magnetic resonance imaging (MRI) in all clinically isolated syndromes (CIS) is controversial. Objective: To assess the value of SC lesions for predicting multiple sclerosis (MS) diagnosis and disability accrual in CIS. Methods: Concerning SC lesions and MS diagnosis (2010 McDonald), adjusted Cox regression analyses were performed in increasingly specific CIS groups: all cases (n = 207), non-SC CIS (n = 143), non-SC CIS with abnormal brain MRI (n = 90) and non-SC CIS with abnormal brain MRI not fulfilling 2010 MS (n = 67). For the outcome Expanded Disability Status Scale (EDSS) ≥3.0, similar analyses were performed in all cases (n = 207), non-SC CIS (n = 143) and SC CIS (n = 64). Performance at 2 years was assessed for all outcomes. Results: The presence of SC lesions increased MS risk 2.0–2.6 times independently of factors like brain lesions. If considering lesion number, the risk ranged from 1.6 to 2.1 for one lesion to 2.4–3.3 for ≥2. SC lesions increased the short-term disability risk around fivefold, better demonstrated in non-SC CIS. SC lesions were very specific for evolution to MS and showed very high sensitivity for EDSS ≥3.0. Conclusion: SC lesions are independent predictors of MS in all CIS and contribute to short-term disability accrual. SC MRIs in CIS could be useful to estimate their prognosis. [ABSTRACT FROM AUTHOR]

Objective: To investigate the association between activity during interferon-beta (IFNβ) therapy and disability outcomes in patients with relapsing–remitting multiple sclerosis (RRMS). Methods: A longitudinal study based on two previously described cohorts of IFNβ-treated RRMS patients was conducted. Patients were classified according to clinical activity after 2 years (clinical cohort) or to clinical and radiological activity after 1 year (magnetic resonance imaging (MRI) cohort). Multivariate Cox models were calculated for early disease activity predicting long-term disability. Results: A total of 516 patients from two different cohorts were included in the analyses. Persistent clinical disease activity during the first 2 years of therapy predicted severe long-term disability (clinical cohort). In the MRI cohort, modified Rio score and no or minimal evidence of disease activity (NEDA/MEDA) did not identify patients with risk of Expanded Disability Status Scale (EDSS) worsening. However, a Rio score ≥ 2 (hazard ratio (HR): 3.3, 95% confidence interval (CI): 1.7–6.4); ≥3 new T2 lesions (HR: 2.9, 95% CI: 1.5–5.6); or ≥2 Gd-enhancing lesions (HR: 2.1, 95% CI: 1.1–4) were able to identify patients with EDSS worsening. Conclusion: Although early activity during IFNβ therapy is associated with poor long-term outcomes, minimal degree of activity does not seem to be predictive of EDSS worsening over 6.7-year mean follow-up.
