Abstract
The relationship between brain diffusion microstructural changes and disability in multiple sclerosis (MS) remains poorly understood. We aimed to explore the predictive value of microstructural properties in white (WM) and grey matter (GM), and identify areas associated with mid-term disability in MS patients. We studied 185 patients (71% female; 86% RRMS) with the Expanded Disability Status Scale (EDSS), timed 25-foot walk (T25FW), nine-hole peg test (9HPT), and Symbol Digit Modalities Test (SDMT) at two time-points. We used Lasso regression to analyse the predictive value of baseline WM fractional anisotropy and GM mean diffusivity, and to identify areas related to each outcome at 4.1 years follow-up. Motor performance was associated with WM (T25FW: RMSE = 0.524, R2 = 0.304; 9HPT dominant hand: RMSE = 0.662, R2 = 0.062; 9HPT non-dominant hand: RMSE = 0.649, R2 = 0.139), and SDMT with GM diffusion metrics (RMSE = 0.772, R2 = 0.186). Cingulum, longitudinal fasciculus, optic radiation, forceps minor and frontal aslant were the WM tracts most closely linked to motor dysfunction, and temporal and frontal cortex were relevant for cognition. Regional specificity related to clinical outcomes provide valuable information that can be used to develop more accurate predictive models that could improve therapeutic strategies.

Abstract
Abstract
Background
There is scarce evidence on fourth doses of SARS-CoV-2 vaccines in chronic kidney disease (CKD) patients. We have evaluated the humoral response and effectivity of the fourth dose in the CKD spectrum: non-dialysis CKD (ND-CKD), hemodialysis (HD), peritoneal dialysis (PD) and kidney transplant (KT) recipients.
Methods
This is a prespecified analysis of the prospective, observational, multicentric SENCOVAC study. In patients with CKD who had received a complete initial vaccination and one or two boosters and had anti-Spike antibody determinations 6 and 12 months after the initial vaccination, we analyzed factors associated to persistent negative humoral response and to higher anti-Spike antibody titers as well as the efficacy of vaccination on COVID-19 severity.
Results
Of 2186 patients (18% KT, 8% PD, 69% HD and 5% ND-CKD), 30% had received a fourth dose. The fourth dose increased anti-Spike antibody titers in HD (P = 0.001) and ND-CKD (P = 0.014) patients and seroconverted 72% of previously negative patients. Higher anti-Spike antibody titers at 12 months were independently associated to repeated exposure to antigen (fourth dose, previous breakthrough infections), previous anti-Spike antibody titers and not being a KT. Breakthrough COVID-19 was registered in 137 (6%) patients, of whom 5% required admission. Admitted patients had prior titers below 620 UI/ml and median values were lower (P = 0.020) than in non-admitted patients.
Conclusions
A fourth vaccine dose increased anti-Spike antibody titers or seroconverted many CKD patients, but those with the highest need for a vaccine booster (i.e. those with lower pre-booster antibody titers or KT recipients) derived the least benefit in terms of antibody titers. Admission for breakthrough COVID-19 was associated with low anti-Spike antibody titers.

Abstract
INTRODUCTION Alemtuzumab is a highly effective drug approved by the European Medicines Agency as a disease-modifying drug for the treatment of relapsing-remitting multiple sclerosis. OBJECTIVE A consensus document was drafted on the management of alemtuzumab in routine clinical practice in Spain. DEVELOPMENT A group of multiple sclerosis specialists reviewed articles addressing treatment with alemtuzumab in patients with multiple sclerosis and published before December 2017. The included studies assessed the drug's efficacy, effectiveness, and safety; screening for infections and vaccination; and administration and monitoring aspects. The initial proposed recommendations were developed by a coordinating group and based on the available evidence and their clinical experience. The consensus process was carried out in 2 stages, with the initial threshold percentage for group agreement established at 80%. The final document with all the recommendations agreed by the working group was submitted for external review and the comments received were considered by the coordinating group. CONCLUSION The present document is intended to be used as a tool for optimising the management of alemtuzumab in routine clinical practice.

Abstract
Introduction
Patients on hemodialysis are at high-risk for complications derived from coronavirus disease-19 (COVID-19). The present analysis evaluated the impact of a booster vaccine dose and breakthrough severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infections on humoral immunity three months after the booster dose.
Methods
This is a multicentric and prospective study assessing IgG anti-Spike antibodies 6 and 9 months after initial SARS-CoV-2 vaccination in patients on hemodialysis that had also received a booster dose before the 6-month assessment (early booster) or between the 6- and 9-month assessments (late booster). The impact of breakthrough infections, type of vaccine, time from the booster and clinical variables were assessed.
Results
A total of 711 patients (67% male, 67 [20-89] years) were included. Of which, 545 (77%) received an early booster and the rest a late booster. At 6 months, 64 (9%) patients had negative anti-Spike antibody titers (3% of early booster and 29% of late booster patients, p = 0.001). At 9 months, 91% of patients with 6-month negative response had seroconverted and there were no differences in residual prevalence of negative humoral response between early and late booster patients (0.9% vs 0.6%, p = 0.693). During follow-up, 35 patients (5%) developed breakthrough SARS-CoV-2 infection. Antibody titers at 9 months were independently associated to mRNA-1273 booster (p = 0.001), lower time from booster (p = 0.043) and past breakthrough SARS-CoV-2 infection (p<0.001).
Conclusions
In hemodialysis patients, higher titers of anti-Spike antibodies at 9 months were associated to mRNA-1273 booster, lower time from booster and past breakthrough SARS-CoV-2 infection.

Abstract
The Crab Nebula is a bright source of gamma rays powered by the Crab Pulsar's rotational energy through the formation and termination of a relativistic electron-positron wind. We report the detection of gamma rays from this source with energies from 5 × 10-4 to 1.1 peta-electron volts with a spectrum showing gradual steepening over three energy decades. The ultrahigh-energy photons imply the presence of a peta-electron volt electron accelerator (a pevatron) in the nebula, with an acceleration rate exceeding 15% of the theoretical limit. We constrain the pevatron's size between 0.025 and 0.1 parsecs and the magnetic field to ≈110 microgauss. The production rate of peta-electron volt electrons, 2.5 × 1036 ergs per second, constitutes 0.5% of the pulsar spin-down luminosity, although we cannot exclude a contribution of peta-electron volt protons to the production of the highest-energy gamma rays.

Abstract
OBJECTIVE Determine the incidence and identify factors associated with potentially avoidable hospital readmissions due to uncontrolled symptoms or minor complications after surgery for gynecologic cancers. METHODS Women who underwent major abdominal or pelvic surgery for a gynecologic malignancy between 2015 and 2017 were identified from the National Surgical Quality Improvement Program targeted hysterectomy dataset. Hospital readmissions within 30 days of surgery were categorized as indicated readmissions or potentially avoidable readmissions by three independent reviewers. Demographic, clinical, and operative covariates were evaluated to determine their association with type of readmission using bivariable tests and adjusted multinomial logistic regression models. RESULTS A total of 20,986 women were identified. 19,814 (94.4%) were not readmitted, 894 (4.3%) were indicated readmissions, and 278 (1.3%) were potentially avoidable readmissions. Among those readmitted, 24% were potentially avoidable readmissions. Presence of ascites, increasing length of stay, and discharge to facility were associated with an increased risk of indicated and potentially avoidable readmissions. Age < 60 years old (RR 1.4, 95%CI 1.1-1.8), BMI ≥ 30 (RR 1.7, 95%CI 1.3-2.3), history of abdominal/pelvic surgery (RR 1.6, 95%CI 1.2-2.1), cervical cancer (RR 2.1, 95%CI 1.4-3.1), and open surgery (RR 2.1, 95%CI 1.4-3.2) were associated with an increased risk of a potentially avoidable readmission but not with increased risk of an indicated readmission. Median time to readmission did not differ between the two readmission groups (indicated = 8 days; avoidable = 7 days; p = .72). CONCLUSIONS Among women with gynecologic cancer, 24% of all unplanned readmissions were attributed to uncontrolled symptoms or minor complications that were potentially avoidable. Age <60 years old, history of previous abdominal/pelvic surgery, obesity, cervical cancer, and open surgery were associated with an increase in risk of a potentially avoidable readmission.

Abstract
INTRODUCTION Cladribine is a prodrug, a synthetic analogue of deoxyadenosine, approved for use as selective immune reconstitution therapy in very active recurring multiple sclerosis in adults. AIMS To review the development of the drug, its mechanism of action and the efficacy and safety data obtained to date, as well as to establish recommendations of Spanish experts for its use in clinical practice. DEVELOPMENT The treatment of multiple sclerosis has been simplified with cladribine tablets, and two short courses of administration for two consecutive years (maximum 20 days) are needed to maintain an efficacy of up to four years after the first dose. Results of clinical trials have demonstrated the safety, tolerability and long-term efficacy of cladribine tablets in patients with recurring multiple sclerosis. Thus, patients treated with cladribine presented a significant reduction in the rate of flare-ups, in the risk of disability progression and in the development of new lesions in magnetic resonance imaging compared to those treated with placebo. In terms of safety, the treated patients had a higher frequency of lymphopenia, in relation to its mechanism of action, and of infections by herpes zoster virus. Long-term results with eight years' follow-up have shown that treated patients are not at greater risk of developing serious events, such as malignant neoplasms or opportunistic infections. CONCLUSIONS Cladribine is the first short-course oral therapy that has been shown to be effective and safe in patients with very active recurring multiple sclerosis, and with a sustained effect over time. The recommendations of Spanish experts on its usage are a fundamental complement to the considerations described by the regulatory agencies.

Abstract
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.

Abstract
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.

Abstract
OBJECTIVE To validate kappa free light chain (KFLC) and lambda free light chain (LFLC) indices as a diagnostic biomarker in multiple sclerosis (MS). METHODS We performed a multicenter study including 745 patients from 18 centers (219 controls and 526 clinically isolated syndrome (CIS)/MS patients) with a known oligoclonal IgG band (OCB) status. KFLC and LFLC were measured in paired cerebrospinal fluid (CSF) and serum samples. Gaussian mixture modeling was used to define a cut-off for KFLC and LFLC indexes. RESULTS The cut-off for the KFLC index was 6.6 (95% confidence interval (CI) = 5.2-138.1). The cut-off for the LFLC index was 6.9 (95% CI = 4.5-22.2). For CIS/MS patients, sensitivity of the KFLC index (0.88; 95% CI = 0.85-0.90) was higher than OCB (0.82; 95%CI = 0.79-0.85; p < 0.001), but specificity (0.83; 95% CI = 0.78-0.88) was lower (OCB = 0.92; 95% CI = 0.89-0.96; p < 0.001). Both sensitivity and specificity for the LFLC index were lower than OCB. CONCLUSION Compared with OCB, the KFLC index is more sensitive but less specific for diagnosing CIS/MS. Lacking an elevated KFLC index is more powerful for excluding MS compared with OCB but the latter is more important for ruling in a diagnosis of CIS/MS.

Abstract
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.

This first part reports on the publication of the new European and American clinical guidelines on the use of disease-modifying treatments and the new diagnostic criteria. It also discusses the strategies for following up patients treated with disease-modifying therapies, reviews cerebral atrophy and biomarkers of neurodegeneration and neuroinflammation, and analyses the role of neuroglia in pathogenesis and treatment. The study examines the natural history of the disease, with the evidence provided by registers, and we anticipate the future thanks to the progress being made in genetics and immunology.

Abstract
Over the past few years, new-generation cell-based assays have demonstrated a robust association of autoantibodies to full-length human myelin oligodendrocyte glycoprotein (MOG-IgG) with (mostly recurrent) optic neuritis, myelitis and brainstem encephalitis, as well as with acute disseminated encephalomyelitis (ADEM)-like presentations. Most experts now consider MOG-IgG-associated encephalomyelitis (MOG-EM) a disease entity in its own right, immunopathogenetically distinct from both classic multiple sclerosis (MS) and aquaporin-4 (AQP4)-IgG-positive neuromyelitis optica spectrum disorders (NMOSD). Owing to a substantial overlap in clinicoradiological presentation, MOG-EM was often unwittingly misdiagnosed as MS in the past. Accordingly, increasing numbers of patients with suspected or established MS are currently being tested for MOG-IgG. However, screening of large unselected cohorts for rare biomarkers can significantly reduce the positive predictive value of a test. To lessen the hazard of overdiagnosing MOG-EM, which may lead to inappropriate treatment, more selective criteria for MOG-IgG testing are urgently needed. In this paper, we propose indications for MOG-IgG testing based on expert consensus. In addition, we give a list of conditions atypical for MOG-EM ("red flags") that should prompt physicians to challenge a positive MOG-IgG test result. Finally, we provide recommendations regarding assay methodology, specimen sampling and data interpretation.

Abstract
The aim of the study was to develop prediction equations for assessing, in vivo, the whole body composition of growing rabbits. The accuracy of the models obtained was externally validated with independent data sets. One hundred fifty rabbits grouped at 5 different ages (25, 35, 49, 63, and 77 d) were used. A body composition analyzer with 4 terminals was used to obtain resistance (Rs; Ω) and reactance (Xc; Ω) values. The distance between internal electrodes (D; cm), body length (Len; cm), and live BW (g) were also registered. Average values of Rs, Xc, impedance (Z), Len, D, and BW were 83.5 ± 23.1 Ω, 18.2 ± 3.8 Ω, 85.6 ± 22.9 Ω, 30.6 ± 6.9 cm, 10.8 ± 3.1 cm, and 1,454 ± 845 g, respectively. At each selected age, animals were slaughtered, ground, and frozen (-20°C) for determining water, fat, CP, ash, and GE (70.5 ± 3.36%, 27.7 ± 7.61% DM, 54.9 ± 5.41% DM, 11.1 ± 1.55% DM, and 2,267 ± 183 kJ/100 g DM, on average, respectively). Fat and GE contents increased with the age, whereas CP, ash, and water contents decreased. A multiple linear regression analysis was used to determine the prediction equations, using BW, Len, and Z data as independent variables. Equations obtained to estimate water (g), CP (g), fat (g), ash (g), and GE (MJ) had coefficient of determination () values of 0.99, 0.99, 0.97, 0.98, and 0.99, respectively, and the relative mean prediction error (RMPE) was 2.79, 6.15, 24.3, 15.2, and 10.6%, respectively. When water was expressed as a percentage, the and RMPE were 0.85 and 2.30%, respectively. When prediction of the content of protein (% DM), fat (% DM), ash (% DM), and energy (kJ/100 g DM) was done, values of 0.79, 0.83, 0.71, and 0.86, respectively, for and 5.04, 18.9, 12.0, and 3.19%, respectively, for RMPE were obtained. It could be concluded that bioelectrical impedance analysis is a good, noninvasive method to estimate, in vivo, whole body composition of growing rabbits from 25 to 77 d of age.

Abstract
For the ninth year in a row the Post-ECTRIMS Meeting has been held in Madrid (Spain) with the aim of presenting and discussing the hottest issues debated at the ECTRIMS Congress by renowned specialists in multiple sclerosis in our country. One outcome of this scientific activity, endorsed by the Spanish Neurology Society, is this review article, which is published in two parts. This second part reflects the current controversy over the management of multiple sclerosis, especially as regards the progressive forms and their differential diagnosis. The work presents the latest advances in remyelination, where the use of the micropillar technique in laboratory stands out, and in neuroprotection, which is reviewed through a study of the optic nerve. Anti-CD20 antibodies are a very promising development and we find ourselves before a new mechanism of action and therapeutic target in cells to which little attention has been paid to date. Another notable fact is the high correlation between the levels of neurofilaments in cerebrospinal fluid and in serum, which could make it possible to avoid the use of cerebrospinal fluid as a biological sample in future studies of biomarkers. The review also provides a preview of the advances in clinical research, which will converge in clinical practice in the future, thereby conditioning the steps that should be taken in the therapeutic management of multiple sclerosis.

Abstract
Background evidence on the effectiveness of interventions to prevent frailty is scarce. Objective to assess the effect of an intervention in preventing frailty progression in pre-frail older people. Study design a randomised, open label, controlled trial with two parallel arms. Population community-dwelling pre-frail older people (≥70 years) consulting in primary care. Intervention nutritional assessment (and derivation to a Nutritional Unit for usual care in the event of nutritional risk) and a physical activity programme including aerobic exercise and a set of mixed strengthening, balance and coordination exercises. Control group patients receiving the usual care. Main outcome measure prevalence of frailty (Fried criteria) at 12 months. Secondary outcomes measures functional capacity (Barthel index), falls and nutritional status (Short-Form Mini Nutritional Assessment) on follow-up at 12 months. Results one hundred and seventy-two participants were recruited and randomised (mean age: 78.3 years; mean number of Fried criteria: 1.45). Thirty-nine participants (22.6%) were dropped out during the study. At follow-up, 4.9% of the intervention group and 15.3% of the control group had evolved to frailty, for a crude odds ratio (OR) of 0.29 (95% confidence interval [CI]: 0.08-1.08; P = 0.052) and an adjusted (by age, gender and number of co-morbidities) OR of 0.19 (95% CI: 0.04-0.95; P = 0.044). Intervention group showed a higher outdoors walking hour per day (0.97 versus 0.73; P = 0.019) but no difference was observed in muscle strength, gait speed or other functional indicators. Conclusion an intervention focused on physical exercise and maintaining good nutritional status may be effective in preventing frailty in community-dwelling pre-frail older individuals. ClinicalTrials.gov identifier NCT02138968.

Abstract
OBJECTIVE Analyse the clinical profile, associated tumour types, and response to treatment of paraneoplastic neurological syndromes associated with antibodies against Ma proteins. METHODS A retrospective study of patients with antibodies against Ma proteins identified in a neuroimmunology laboratory of reference. RESULTS Of the 32 patients identified, 20 showed reactivity against Ma2 only (anti-Ma2 antibodies), 11 against Ma1 and Ma2 (anti-Ma antibodies), and 1 with reactivity against Ma1 only (anti-Ma1 antibodies). The most common clinical presentations were limbic encephalopathy, diencephalic dysfunction, or brainstem encephalopathy, frequently appearing as a combination of these features. Three patients had isolated cerebellar dysfunction with anti-Ma antibodies, and 2 exhibited peripheral nervous system syndrome with anti-Ma2 antibodies. Testicular tumours were the most common neoplasms (40%) in the anti-Ma2 cases. In the group associated with anti-Ma1 antibodies, the most common were lung tumours (36%), followed by testicular tumours. All idiopathic cases were reactive to Ma2. The clinical outcome was significantly better in the anti-Ma2 group. The patient with anti-Ma1 presented with limbic encephalitis and brainstem dysfunction associated with lymphoepithelioma of the bladder. CONCLUSIONS Specifically determining the different reactivities of anti-Ma protein antibodies in order to differentiate between Ma1 and Ma2 antibodies is important because anti-Ma2-associated paraneoplastic syndromes have a better outcome. Lastly, this study is the first to confirm that there may be cases that react exclusively to antibodies against Ma1.

Abstract
Renowned national specialists in multiple sclerosis (MS) met, for the eighth year in a row, to give details of the latest novelties presented at the last ECTRIMS Congress 2015, which are included in this review. One of the highlights at this Congress was the new classification of the phenotypes of MS. Both the diagnostic criteria of the neuromyelitis optica spectrum and the problems involved in the differential diagnosis derived from the lack of definition of the radiological spectrum were reviewed. The microbiota comes to the fore as a possible factor determining the disease, together with extrinsic factors such as tobacco, salt ingestion or vitamin D deficiency. Advances made in immunomodulation are driving the progress being made in the treatment of MS. Ocrelizumab is the first treatment with positive results in the primarily progressive forms and tocilizumab, a drug product for rheumatoid arthritis, stands out as a potential candidate for the treatment of neuromyelitis optica. Certain antibiotics and vitamins could also play a role in the treatment of MS. In this edition of the Congress special attention was paid to personalised therapy. To date, 11 drugs have been approved for use in Europe. There is a need for therapeutic algorithms that help us to choose the best treatment for each patient. Likewise, we need to be able to identify, in the early stages of the disease, the risk of developing disability, so as to be able to design therapeutic strategies. To do so, molecular biomarkers and other predictive tools are required. The problems that still exist in software technology in magnetic resonance hinder its application in daily clinical practice.

Abstract
BACKGROUND Characterization of the main features of pre-frailty may contribute to better understanding the mechanisms involved in the development of frailty. OBJECTIVE To characterize the pre-frail population consulting in primary care centres in Mataró (Catalonia, Spain), to describe the Fried's frailty criteria for this population and to identify the main associated factors. DESIGN Cross-sectional study. SETTING Three primary care centres in Catalonia. PARTICIPANTS Pre-frail subjects recruited from among persons aged 70 years and older consulting primary care centres and screened for frailty according to Fried's criteria. MEASUREMENTS Clinical, nutritional and functional data. RESULTS Frailty prevalence of 31.0% and pre-frailty prevalence of 49.0% were observed. Comorbidity was not especially frequent among elderly individuals classified as pre-frail (except for diabetes with 35.8% prevalence). Functional status and nutritional status were both reasonably satisfactory in pre-frail subjects with mean Barthel score of 98 points and 91% classified as well nourished. Among pre-frail subjects, 35% were obese (body mass index>30); 75% reported pain; 12% had an accidental fall in the previous three months; and the mean number of medications ingested was 6.2. Weakness was the most prevalent frailty criterion (70%), followed by slowness (30%). Weakness was associated with age in men and with pain in women. Poor physical activity was associated with pain. CONCLUSIONS Pre-frailty is very common among elderly subjects consulting primary care centres. Weakness, slowness, diabetes, pain and polypharmacy should alert healthcare professionals to the onset of a frailty process.

Abstract
BACKGROUND Recent studies show an increasing incidence of multiple sclerosis (MS) in southern Europe. Although by its geographical location and genetic characteristics Spain is expected to be similar to other southern European regions, data on incidence are scarce. The aim of this study was to determine the onset-adjusted incidence of MS in the Girona province in Catalonia (Spain). METHODS A prospective incidence study pooling data from the population-based Catalonia MS Registry was performed. Incident cases were defined as patients who had the onset of symptoms compatible with a clinically isolated syndrome (CIS) suggestive of MS in 2009 and fulfilled McDonald-2005 criteria during follow-up. Age- and sex-specific incidence rates were obtained. RESULTS The Registry included 182 patients residing in Girona that presented a CIS from January 2009 to December 2013. Fifty one patients had the onset of symptoms in 2009, of whom 27 patients fulfilled the diagnostic criteria, giving an incidence of 3.6 per 100,000 (CI 95% 2.4-5.3) inhabitants; 4.3 (CI 95% 2.5-7.1) for women and 2.9 (CI 95% 1.4-5.2) for men. The age-adjusted incidence rate for the European population was 3.29 (CI 95% 3.2-3.3). CONCLUSION The incidence estimation derived in this study is consistent with recent epidemiological data of MS in southern Europe suggesting an increase in incidence in this region.

Abstract
For the seventh year in a row the Post-ECTRIMS Meeting has been held in Madrid (Spain). Renowned specialists in multiple sclerosis and national leaders in this area have gathered once again to discuss the novelties presented at the 2014 ECTRIM-ACTRIMS World Congress. That meeting gave rise to this review, which is published in two parts. This second part shows that immunological phenomena are increasingly more present in the pathogenesis of the disease, and that the interaction between inflammation and neurodegeneration is becoming more apparent. Metabolic, mitochondrial dysfunction and oxidative stress phenomena are also involved in axonal degeneration and the experimental models open up the way to promising new therapeutic approaches for regenerative strategies. Although ambitious, inducible neural progenitor cells have become a promising alternative to the conventional treatments with stem cells, and the identification of new genetic variants of susceptibility to multiple sclerosis opens up the way to the discovery of new drugs. Reconsidering the value of old drugs and procedures would be another alternative therapeutic development.

Abstract
For the seventh year in a row the Post-ECTRIMS Meeting has been held in Madrid (Spain). Renowned specialists in multiple sclerosis and national leaders in this area have gathered once again to discuss the novelties presented at the 2014 ECTRIM-ACTRIMS World Congress. That meeting gave rise to this review, which will be published in two parts. One of the main conclusions in this first part is the deeper understanding of the genetic component of multiple sclerosis that we are acquiring, although it is still insufficient unless we bear in mind its interaction with the environmental risk factors of the disease or the impact of comorbidity and healthy habits on the patients' susceptibility and prognosis. In this respect, the authors insist on the fact that, in clinical practice, the cognitive and psychiatric disorders remain under-diagnosed and are rarely taken into account in clinical research. Yet, although scarce, the evidence we have points to the possible benefits of disease-modifying drugs and alternatives to treatment with selective serotonin reuptake inhibitors. Addressing the sub-populations in multiple sclerosis and variants of the disease enhances the importance of an early accurate diagnosis in order to offer patients a safer and more personalised prognosis and treatment. Paediatric multiple sclerosis is ideal for studying the risk factors of the disease but, given its low prevalence, the use of prospective studies raises a number of doubts and there is a preference for conducting collaborative studies.

Abstract
Background and objective: We explored which clinical and biochemical variables predict conversion from clinically isolated syndrome (CIS) to clinically definite multiple sclerosis (CDMS) in a large international cohort. Methods: Thirty-three centres provided serum samples from 1047 CIS cases with at least two years’ follow-up. Age, sex, clinical presentation, T2-hyperintense lesions, cerebrospinal fluid (CSF) oligoclonal bands (OCBs), CSF IgG index, CSF cell count, serum 25-hydroxyvitamin D3 (25-OH-D), cotinine and IgG titres against Epstein-Barr nuclear antigen 1 (EBNA-1) and cytomegalovirus were tested for association with risk of CDMS. Results: At median follow-up of 4.31 years, 623 CIS cases converted to CDMS. Predictors of conversion in multivariable analyses were OCB (HR = 2.18, 95% CI = 1.71–2.77, p < 0.001), number of T2 lesions (two to nine lesions vs 0/1 lesions: HR = 1.97, 95% CI = 1.52–2.55, p < 0.001; >9 lesions vs 0/1 lesions: HR = 2.74, 95% CI = 2.04–3.68, p < 0.001) and age at CIS (HR per year inversely increase = 0.98, 95% CI = 0.98–0.99, p < 0.001). Lower 25-OH-D levels were associated with CDMS in univariable analysis, but this was attenuated in the multivariable model. OCB positivity was associated with higher EBNA-1 IgG titres. Conclusions: We validated MRI lesion load, OCB and age at CIS as the strongest independent predictors of conversion to CDMS in this multicentre setting. A role for vitamin D is suggested but requires further investigation.

Abstract
Neuromyelitis optica (NMO) is an inflammatory autoimmune disease of the central nervous system that preferentially targets the optic nerves and spinal cord. The clinical presentation may suggest multiple sclerosis (MS), but a highly specific serum autoantibody against the astrocytic water channel aquaporin-4 present in up to 80% of NMO patients enables distinction from MS. Optic neuritis may occur in either condition resulting in neuro-anatomical retinal changes. Optical coherence tomography (OCT) has become a useful tool for analyzing retinal damage both in MS and NMO. Numerous studies showed that optic neuritis in NMO typically results in more severe retinal nerve fiber layer (RNFL) and ganglion cell layer thinning and more frequent development of microcystic macular edema than in MS. Furthermore, while patients’ RNFL thinning also occurs in the absence of optic neuritis in MS, subclinical damage seems to be rare in NMO. Thus, OCT might be useful in differentiating NMO from MS and serve as an outcome parameter in clinical studies.

Abstract
The most relevant data presented at the 29th Congress of the European Committee for Treatment and Research in Multiple Sclerosis (ECTRIMS), held in October 2013 in Denmark, were summarised at the sixth edition of the Post-ECTRIMS Expert Meeting, held in Madrid in October 2013, resulting in this review, to be published in three parts. This first part of the Post-ECTRIMS review presents an update on gender differences in multiple sclerosis (MS) as well as new evidence on the impact of sex hormones on the disease. We should consider that there is still much to discover with regard to the genetic components of the disease. Similarly, possible infections and lifestyle habits are added as triggers of the known environmental risk factors for MS. The interaction between genetics and the environment has been increasingly implicated as a cause of susceptibility to MS. With regard to the mechanisms of inflammation, axo-glial proteins, instead of myelin proteins, may be the early antigenic targets, and B cells have been implicated in the production of cytokines toxic to oligodendrocytes. Chitinase 3-like 1 (CHI3L1) is validated as a prognostic marker of conversion to MS, and immunoglobulin M oligoclonal bands and L-selectin could be incorporated as possible measures of the risk stratification strategy in patients treated with natalizumab.

Abstract
UNLABELLED Our aim was to investigate differences in immune mechanisms in multiple sclerosis (MS) relapse, after high-dose oral methylprednisolone (oMP) or intravenous methylprednisolone (ivMP). We measured serum cytokines (IL-2, IL-4, IL-6, IL-10, IL-17, TNF-α and IFN-γ) in 39 of 49 MS patients with moderate-severe relapse, whom were treated with ivMP or oMP in a placebo-controlled, non-inferiority clinical trial. We assessed these cytokine levels at baseline and at 1 and 4 weeks post-treatment. The cytokine levels between oMP and ivMP were similar at any time. Proinflammatory cytokines (IL-6 and IFN-γ) were significantly decreased in both groups at week 1 (p = 0.05 / p = 0.03) and at week 4 (p = 0.04 / p = 0.05). This study provides further confirmatory evidence that oMP is not inferior to ivMP. TRIAL REGISTRATION clinicaltrials.gov identifier: NCT00753792.

Abstract
BACKGROUND There is increasing evidence supporting that neuromyelitis optica (NMO) is an inflammatory humoral mediated disorder associated with NMO-IgG/AQP-4 antibodies. However, little is known about the subsets of B cells and T cells that contribute to the pathogenesis or therapy response. OBJECTIVES To describe the clinical and immunological changes associated with intravenous immunoglobulins (IV-Igs) plus rituximab (RTX) in a patient with a severe acute attack of NMO and intrathecal synthesis of NMO-IgG/AQP-4, who previously did not respond to intravenous methylprednisolone and plasma exchange. METHODS We sequentially analysed the levels of NMO-IgG/AQP-4 by immunohistochemistry, and B and T cells subsets by multiparametric flow-cytometry, in the CSF and peripheral blood (PB), before and alter IV-Igs plus RTX therapy. RESULTS In the CSF before treatment, and compared with PB, there was a higher percentage of CD4(+) T cells and a lower percentage of CD8(+) T cells and CD19(+) B cells. After therapy, the percentage of CD4(+) T cells remained high, and that of CD8(+) T cells increased. The observed decrease in the percentage of CD19(+) B cells was lower than in the PB. When the CSF was compared, it was found that the percentage of effector-memory and effector CD8(+) T cells had increased after therapy, and that of IgM memory B cells and switched-memory B cells decreased. The observed changes paralleled the decrease of NMO-IgG/AQP-4 results to negative and the clinical improvement. CONCLUSIONS Our findings confirm that, besides intrathecal humoral immune response against AQP4, B and T cell subsets are involved in the modulation of inflammation within and outside the central nervous system.

Abstract
INTRODUCTION Natalizumab treatment has been shown to be very efficacious in clinical trials and very effective in clinical practice in patients with relapsing-remitting multiple sclerosis, by reducing relapses, slowing disease progression, and improving magnetic resonance imaging patterns. However, the drug has also been associated with a risk of progressive multifocal leukoencephalopathy (PML). The first consensus statement on natalizumab use, published in 2011, has been updated to include new data on diagnostic procedures, monitoring for patients undergoing treatment, PML management, and other topics of interest including the management of patients discontinuing natalizumab. MATERIAL AND METHODS This updated version followed the method used in the first consensus. A group of Spanish experts in multiple sclerosis (the authors of the present document) reviewed all currently available literature on natalizumab and identified the relevant topics would need updating based on their clinical experience. The initial draft passed through review cycles until the final version was completed. RESULTS AND CONCLUSIONS Studies in clinical practice have demonstrated that changing to natalizumab is more effective than switching between immunomodulators. They favour early treatment with natalizumab rather than using natalizumab in a later stage as a rescue therapy. Although the drug is very effective, its potential adverse effects need to be considered, with particular attention to the patient's likelihood of developing PML. The neurologist should carefully explain the risks and benefits of the treatment, comparing them to the risks of multiple sclerosis in terms the patient can understand. Before treatment is started, laboratory tests and magnetic resonance images should be available to permit proper follow-up. The risk of PML should be stratified as high, medium, or low according to presence or absence of anti-JC virus antibodies, history of immunosuppressive therapy, and treatment duration. Although the presence of anti-JC virus antibodies is a significant finding, it should not be considered an absolute contraindication for natalizumab. This update provides general recommendations, but neurologists must use their clinical expertise to provide personalised follow-up for each patient.

Abstract
There are no specific recommendations in clinical guidelines about the best time, imaging tests, or intervals for following up patients with intracranial aneurysms treated with endovascular techniques. We reviewed the literature, using the following keywords to search in the main medical databases: cerebral aneurysm, coils, endovascular procedure, and follow-up. Within the Cerebrovascular Disease Group of the Spanish Society of Neuroradiology, we aimed to propose recommendations and an orientative protocol based on the scientific evidence for using neuroimaging to monitor intracranial aneurysms that have been treated with endovascular techniques. We aimed to specify the most appropriate neuroimaging techniques, the interval, the time of follow-up, and the best approach to defining the imaging findings, with the ultimate goal of improving clinical outcomes while optimizing and rationalizing the use of available resources.

Abstract
Background: Steroids improve multiple sclerosis (MS) relapses but therapeutic window and dose, frequency and administration route remain uncertain. Objective: The objective of this paper is to compare the clinical and radiologic efficacy, tolerability and safety of intravenous methylprednisolone (ivMP) vs oral methylprednisolone (oMP), at equivalent high doses, for MS relapse. Methods: Forty-nine patients with moderate or severe relapse within the previous 15 days were randomized in a double-blind, noninferiority, multicenter trial to receive ivMP or oMP and their matching placebos. Expanded Disability Status Scale (EDSS) scores were determined at baseline and weeks 1, 4 and 12. Brain MRI were assessed at baseline and at weeks 1 and 4. Primary endpoint was a noninferiority assessment of EDSS improvement at four weeks (noninferiority margin of one point), with further key efficacy assessments of number and volume of T1 gadolinium-enhancing (Gd+), and new or enlarged T2 lesions at four weeks’ post-treatment initiation. Secondary outcomes were safety and tolerability. Results: The study achieved the main outcome of noninferiority at four weeks for improved EDSS score. No differences were found between ivMP and oMP in the number of Gd+ lesions (0 (0–1) vs 0 (0–0.5), p = 0.630), volume of Gd+ lesions (0 (0–88.0) vs 0 (0–32.9) mm3, p = 0.735), or new or enlarged T2 lesions (0 (0–194) vs 0 (0–123), p = 0.769). MP was well tolerated, and no serious adverse events were reported. Conclusions: This study provides confirmatory evidence that oMP is not inferior to ivMP in reducing EDSS, similar in MRI lesions at four weeks for MS relapses and is equally well tolerated and safe. Trial registration: clinicaltrials.gov identifier: NCT00753792

Abstract
The most relevant data presented at the 28th edition of the European Committee for Treatment and Research in Multiple Sclerosis (ECTRIMS) held in October 2012 in France have been summarised in the fifth edition of the Post-ECTRIMS Expert Meeting held in Madrid in October 2012. This review is the result of the meeting, which is being published in three parts. This second part of the Post-ECTRIMS review discusses the biology of recovery and remyelination in multiple sclerosis (MS) as well as the different repair and endogenous and exogenous remyelination strategies currently being evaluated based on the fact that resident microglia and oligodendroglial progenitor cells have been implicated in the remyelination process. This review also discusses the current state and future use of biomarkers in MS and proposes as markers of neurodegeneration the following: T2 lesion volume and brain atrophy using MRI and the loss of the ganglion cell layer as assessed by optical coherence tomography. A greater future utility for double inversion recovery (DIR) sequences is proposed to correlate cognitive impairment with MS impairment, given its higher diagnostic yield in locating and defining cortical lesions. The availability of novel biomarkers in the future requires strict validation. In this context, this paper proposes possible areas of action to improve the current situation and also presents the latest research results in identifying potential candidates with useful diagnostic characteristics, prognostic characteristics, treatment responses, and safety procedures.

Abstract
OBJECTIVE To describe the main characteristics of patients with primary Sjögren syndrome (SS) and white matter abnormalities (WMA) seen by a specialist SS unit. METHODS The study cohort included 321 consecutive patients fulfilling the 2002 classification criteria for primary SS. We retrospectively analyzed the results of neuroimaging studies performed in patients who presented with neurological symptoms. Patients were further evaluated by three neurologists to determine fulfillment of the McDonald criteria for the diagnosis of multiple sclerosis (MS). RESULTS Fifty-one (16%) patients had at least one neuroimaging study, and 25 of these had WMA. WMA were classified as vascular pathological changes in 21 patients: 10 had multiple small focal lesions, 7 had beginning confluence of lesions and 4 had diffuse involvement of the entire region. WMA were classified as inflammatory/demyelinating lesions (MS-like) in 4 patients who fulfilled the MRI Barkhof criteria. Patients with inflammatory/demyelinating lesions were younger (53.7 vs. 73.5 years, P = 0.001) and had a lower frequency of hypertension (25% vs. 86%, P = 0.031) and altered glomerular filtration rate (0% vs. 70%, P = 0.047) in comparison with patients with vascular lesions. The multivariate age-sex adjusted model including the seven variables which were statistically significant in the univariate analysis (antimalarial therapy, leukopenia, anti-La/SSB antibodies, diabetes, hypertension, metabolic syndrome and HDL-c levels) identified hypertension (P = 0.019) and HDL-c levels (P = 0.032) as independent predictors of WMA in primary SS patients. CONCLUSION Neuroimaging studies disclosed WMA in 49% of patients with primary SS and suspected neurological involvement. WMA were identified as vascular pathological changes in 80% of the patients, and hypertension and HDL-c levels as predictive factors for this association.
