The aim of this study was to assess patients’ decisional conflict regarding the choice of a disease-modifying therapy and its associated factors in patients with mid-stage relapsing-remitting multiple sclerosis (RRMS).Methods: A multicenter, non-interventional study was conducted. Adult patients with a diagnosis of RRMS (2017 revised McDonald criteria) and disease duration of 3 to 8 years were included. The level of uncertainty experienced by a patient when faced with making a treatment choice was assessed using the 4-item Decisional Conflict Scale. A battery of patient-reported and clinician-rated measures was administered to obtain information on symptom severity, illness perception, illness-related uncertainty, regret, MS knowledge, risk taking behavior, preferred role in the decision-making process, cognition, and self-management. Patients were recruited during routine follow-up visits and completed all questionnaires online using electronic tablets at the hospital. A multivariate logistic regression analysis was conducted.Results: A total of 201 patients were studied. Mean age (Standard deviation) was 38.7 (8.4) years and 74.1% were female. Median disease duration (Interquartile range) was 6.0 (4.0– 7.0) years. Median EDSS score was 1.0 (0– 2.0). Sixty-seven (33.3%) patients reported a decisional conflict. These patients had lower MS knowledge and more illness uncertainty, anxiety, depressive symptoms, fatigue, subjective symptom severity, a threatening illness perception, and poorer quality of life than their counterparts. Lack of decisional conflict was associated with MS knowledge (Odds ratio [OR]=1.195, 95% CI 1.045, 1.383, p=0.013), self-management (OR=1.049, 95% CI 1.013, 1.093, p=0.018), and regret after a healthcare decision (OR=0.860, 95% CI 0.756, 0.973, p=0.018) in the multivariate analysis.Conclusion: Decisional conflict regarding the selection of a disease-modifying therapy was a common phenomenon in patients with mid-stage RRMS. Identifying factors associated with decisional conflict may be useful to implement preventive strategies that help patients better understand their condition and strengthen their self-management resources.Keywords: multiple sclerosis, disease-modifying therapies, decision-making, decisional conflict, disease-related knowledge, self-management

There is little information on this phenomenon among patients with relapsing-remitting multiple sclerosis (RRMS), one of the most common causes of disability and loss of autonomy in young adults. The aim of this study was to assess state hopelessness and its associated factors in early-stage RRMS.Methods: A multicenter, non-interventional study was conducted. Adult patients with a diagnosis of RRMS, a disease duration ≤ 3 years, and an Expanded Disability Status Scale (EDSS) score of 0– 5.5 were included. The State-Trait Hopelessness Scale (STHS) was used to measure patients´ hopelessness. A battery of patient-reported and clinician-rated measurements was used to assess clinical status. A multivariate logistic regression analysis was conducted to determine the association between patients’ characteristics and state hopelessness.Results: A total of 189 patients were included. Mean age (standard deviation-SD) was 36.1 (9.4) years and 71.4% were female. Median disease duration (interquartile range-IQR) was 1.4 (0.7, 2.1) years. Symptom severity and disability were low with a median EDSS (IQR) score of 1.0 (0, 2.0). A proportion of 65.6% (n=124) of patients reported moderate-to-severe hopelessness. Hopelessness was associated with older age (p=0.035), depressive symptoms (p=< 0.001), a threatening illness perception (p=0.001), and psychological and cognitive barriers to workplace performance (p=0.029) in the multivariate analysis after adjustment for confounders.Conclusion: Hopelessness was a common phenomenon in early-stage RRMS, even in a population with low physical disability. Identifying factors associated with hopelessness may be critical for implementing preventive strategies helping patients to adapt to the new situation and cope with the disease in the long term.Keywords: relapsing-remitting multiple sclerosis, hopelessness, depressive symptoms, workplace difficulties, suicide

The Caregiver Strain Index (CSI) is a brief self-assessment tool for measuring the caregivers’ perceived level of burden. Limited information is available on the psychometric performance of the CSI in MS.Objective: The objective of this study was to assess the factor structure and construct validity of the CSI in MS.Methods: A multicenter, cross-sectional study in adults with relapsing-remitting and primary-progressive MS (McDonald 2010 criteria) was conducted. A non-parametric item response theory (IRT) procedure, Mokken analysis, was conducted to assess the dimensional structure of the CSI. A parametric IRT model for dichotomous responses, Rasch model, was conducted to assess item characteristics. Discriminative validity was assessed comparing the distribution of its overall score between people with mild and moderate-severe disability according to the Expanded Disability Status Scale.Results: A total of 72 MS caregivers were studied. The prevalence of a high level of strain was 23.6% (n=17). Internal reliability was high (Cronbach’s alpha =0.91). According to Mokken analysis, CSI represented a unidimensional construct of caregiver burden although two of the total 13 items (#1 and #13) could not be assigned to any factor by an automatic item selection procedure. Without these items, the scalability moved from a weak (Hi =0.37) to a medium scale (Hi =0.44). However, the item characteristic curve of the Rasch model showed a range of appropriate difficulty and the item and person parameters showed good fit (Andersen likelihood ratio test =18.40, df =11; P-value =0.07; all item values for the infit). The CSI score showed a good discriminative validity between the levels of disability of the care recipient.Conclusion: The CSI questionnaire shows appropriate psychometric characteristics being a useful instrument to assess different aspects of burden in MS caregivers in clinical practice.

Justification. The professors of Communication transfer many of the previously consumed items to the classroom, as a basis for case-studies. Methodology. This paper analyzes, by means of survey techniques, the media consumption of Spanish (Valladolid University) and Mexican professors (La Salle University, Mexico City), assessing their informational habits, their priority, and their perception of quality assigned to the different media, as well as their extent of interactivity with them. Results and conclusions. Findings reveal that the professors' access to press, radio and television, besides being daily, demonstrates the prevalent use of traditional supports and formats; in addition, the latest types of information devices - smartphone, tablet and laptop - show an intermediate penetration among these professionals; finally, we find the fact that the professors interact with journalistic companies primarily through comments on the most relevant news, made in social networks.

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 FROM AUTHOR]

The article focuses on the study which compares the clinical and radiologic efficacy of intravenous methylprednisolone (ivMP) against oral methylprednisolone (oMP) at equivalent high doses for multiple sclerosis (MS) relapse. It states the main outcome of noninferiority at four weeks for improved expanded disability status scale (EDSS) score. It mentions that oMP is not inferior to ivMP in reducing the score of EDSS.

Multiple sclerosis (MS) is a chronic demyelinating disease, which represents a great economic burden to society. Cost-of-illness studies of MS tend to underestimate the intangible costs related to pain, anxiety and helplessness. The purpose of this study was to estimate the intangible costs of MS, and determine whether these costs increase as disability progresses. We studied 211 consecutive patients with MS who attended our MS unit. Patients mean age was 41.6 (SD: 10.7) years, 69% were female, and their mean Expanded Disability Status Scale (EDSS) score was 2.47 (SD: 2.05). Quality-of-life was measured with the EuroQoL visual analogue scale. Quality-adjusted life year (QALY) was calculated for each patient. Patients were grouped into five disability stages according to their EDSS, and QALY was compared between patients and a group of healthy controls matched by age and sex. A benchmark value was ascribed to each QALY lost, and the intangible costs per patient-year were calculated as ϵ0 (EDSS = /0), ϵ1100 (EDSS = /1–3), ϵ8250 (EDSS = 3.5–5.5), ϵ9900 (EDSS = /6–7) and ϵ11 000 (EDSS > /7.5). Sensitivity analysis showed a similar progression of costs. We conclude that intangible costs are relevant in MS, especially when disability increases. Although the method to calculate the costs remains controversial, we consider that they should be included in cost analysis of MS. [ABSTRACT FROM AUTHOR]

In order to ensure sufficient disease activity, patients with relapsing remitting (RR) multiple sclerosis (MS) are often included in randomized placebo-controlled trials, only if they have a high baseline activity. These patients, whose evolution is unusual in the pre-study period, will tend to show a more usual behavior when followed up over a period of time. This phenomenon is known as regression to the mean. Regression to the mean should be taken into account in correctly interpreting long-term studies of cohorts treated without a placebo control group, which use the baseline period as control. The aim of this study was to evaluate the relevance of this phenomenon in a non-treated cohort of RRMS patients, selected with similar criteria to those used in randomized placebo-controlled clinical trials. Forty-four patients with definite RRMS, with two or more relapses in the previous two years, and a baseline EDSS ≤5.5 were prospectively followed. The mean number of relapses spontaneously decreased from 1.72 (SD: 1.4) in the year prior to enrolment, to 1.0 (SD: 1.3) during the first year of follow-up (P < 0.05). Regression to the mean may explain as much as 40% of the reduction in the relapse rate from the baseline period to the period on-study. [ABSTRACT FROM AUTHOR]

Abstract Background Multiple sclerosis (MS) is an incurable chronic disease that predominantly affects young adults. It has a high socio-economic impact which increases as disability progresses. An assessment of the real costs of MS may contribute to our knowledge of the disease and to treat it more efficiently. Our objective is to assess the direct and indirect costs of MS from a societal perspective, in patients monitored in our MS Unit (Baix Llobregat, Catalonia) and grouped according to their disability (EDSS). Methods We analysed data from 200 MS patients, who answered a questionnaire on resource consumption, employment and economical status. Mean age was 41.6 years, mean EDSS 2.7, 65.5% of patients were female, 79.5% had a relapsing-remitting course, and 67.5% of them were receiving immunomodulatory treatment (IT). Patients were grouped into five EDSS stages. Data from the questionnaires, hospital charts, Catalan Health Service tariffs, and figures from Catalan Institute of Statistics were used to calculate the direct and indirect costs. The cost-of-illness method, and the human capital approach for indirect costs, were applied. Sensitivity analyses were performed to strengthen results. Results The mean total annual cost of MS per patient results 24272 euros. This cost varied according to EDSS: 14327 euros (EDSS = 0), 18837 euros (EDSS = 1–3), 27870 euros (EDSS = 3.5–5.5), 41198 euros (EDSS = 6–7) and 52841 euros (EDSS>7.5). When the mean total annual costs was adjusted by the mean % of patients on IT in our Unit (31%) the result was 19589 euros. The key-drivers for direct costs were IT in low EDSS stages, and caregiver costs in high stages. Indirect costs were assessed in terms of the loss of productivity when patients stop working. Direct costs accounted for around 60% of total costs in all EDSS groups. IT accounts from 78% to 11% of direct costs, and decreased as disability progressed. Conclusion The total mean social costs of MS in a cohort from Baix Llobregat (Catalonia) were estimated at 24272 euros per patient/year, and ranged between 14327 euros (EDSS = 0) and 52841 euros (EDSS = 7.5–9.5). Total costs, and particularly informal and direct costs, increased as the disability progressed. IT should be able to delay the progression of disability to be efficient and not only effective.

Abstract: Metabolic disturbances are often associated with epileptic seizures, but the pathogenesis of this relationship is poorly understood. We describe the case of a 48-year-old man who presented with complex partial status epilepticus with visual seizures in the context of ketotic hyperglycemia. The EEG revealed a temporal epileptogenic focus and alterations were apparent on MRI in the acute phase and 4months later. Very few cases of seizures in ketotic patients have been reported because ketone bodies have a protective effect against epilepsy. Seizures in hyperglycemia tend to be partial, and the only reports of visual seizures were due to occipital foci. Neuroradiological alterations have been reported in epileptic seizures, although usually in generalized seizures. The clinical, electrical, and imaging characteristics of this case are interesting and suggest that partial seizures can also cause long-term neuronal damage. [Copyright &y& Elsevier]
