Education needs in palliative care and advance care planning of Italian residents in neurology: an online survey.

BACKGROUND AND PURPOSE: Most neurological diseases have a chronic and progressive clinical course, with patients living for extended periods with complex healthcare needs. Evidence from other countries suggests that palliative care (PC) is insufficiently integrated in the care of these patients. This study aims to identify PC and advance care planning (ACP) knowledge and the perceived preparedness of Italian residents in neurology. METHODS: This is a cross-sectional online survey of physicians attending the 36 Italian neurology residency programmes. RESULTS: Of 854 residents, 188 (22%) participated. Their mean age was 28.4 ± 2.0 years; 49% were women; 45% were from the north, 23% from the centre and 32% from the south of Italy. Few residents (6%) reported that a teaching course in PC was part of the graduate programme, and 3% of the postgraduate programme. During their residency, 9% of participants received PC training, and 18% ACP training. Only 13% reported to have participated in the ACP process, half within their neurology residency programme. Residents considered PC support very/extremely important in all the pre-specified clinical situations, with values ranging between 78% and 96%. Over 70% of residents revealed education needs, particularly concerning ACP. CONCLUSIONS: Our data confirm the need for improving PC training in the graduate and postgraduate curriculum. This, together with collaboration and joint training of neurology and PC, is essential to improve the quality and continuity of care and respond to the complex needs of people with neurological disorders causing severe disability.

Cross-cultural validity and reliability of the comprehensive assessment of acceptance and commitment therapy processes (CompACT) in people with multiple sclerosis.

PURPOSE: The Comprehensive assessment of Acceptance and Commitment Therapy (CompACT) is a 23-item questionnaire measuring psychological flexibility, a quality of life protective factor. An 18-item version was recently produced. We assessed validity and reliability of CompACT, and equivalence of paper and electronic (eCompACT) versions in people with multiple sclerosis (PwMS) in Italy, Germany and Spain. METHODS: We used confirmatory factor analysis and assessed CompACT-23 and CompACT-18 measurement invariance between the three language versions. We assessed construct validity (Spearman's correlations) and internal consistency (Cronbach's alpha). Test-retest reliability (intraclass correlation coefficient, ICC) and equivalence of paper and eCompACT (ICC and linear regression model for repeated measures) were assessed in subsamples of PwMS. RESULTS: A total of 725 PwMS completed the study. The three-factor structure of the CompACT-23 showed poor fit (RMSEA 0.07; CFI 0.82; SRMR 0.08), while the fit of the CompACT-18 was good (RMSEA 0.05; CFI 0.93; SRMR 0.05). Configural and partial metric invariance were confirmed, as well as partial scalar invariance (reached when five items were allowed to vary freely). The CompACT-18 showed good internal consistency (all alpha ≥ 0.78); and test-retest reliability (all ICCs ≥ 0.86). Equivalence between paper and eCompACT was excellent (all ICCs ≥ 0.86), with no mode, order, or interaction effects. CONCLUSION: Results support using the refined CompACT-18 as a three-factor measure of psychological flexibility in PwMS. Paper and eCompACT-18 versions are equivalent. CompACT-18 can be used cross-culturally, but sub-optimal scalar invariance suggests that direct comparison between the three language versions should be interpreted with caution.

User appraisal of a booklet for advance care planning in multiple sclerosis: a multicenter, qualitative Italian study.

OBJECTIVES: Implementation of advance care planning (ACP) in people with progressive multiple sclerosis (PwPMS) is limited. We aimed to involve users (PwPMS, significant others, and healthcare professionals involved in PwPMS care) in the evaluation and refinement of a booklet to be used during the ACP conversations. METHODS: This qualitative study consisted of cognitive interviews with PwPMS and significant others and a focus group with healthcare professionals from three Italian centers. We analyzed the interviews using the framework method and the focus group using thematic analysis. RESULTS: We interviewed 10 PwPMS (3 women; median age 54 years; median Expanded Disability Status Scale score 6.0) and three significant others (2 women; 2 spouses and one daughter). The analysis yielded three themes: booklet comprehensibility and clarity, content acceptability and emotional impact, and suggestions for improvement. Twelve healthcare professionals (7 neurologists, 3 psychologists, one nurse, and one physiotherapist) participated in the focus group, whose analysis identified two themes: booklet's content importance and clarity and challenges to ACP implementation. Based on analysis results, we revised the booklet (text, layout, and pictures) and held a second-round interviews with two PwPMS and one significant other. The interviewees agreed on the revisions but reaffirmed their difficulty in dealing with the topic and the need for a physician when using the booklet. CONCLUSIONS: Appraisal of the booklet was instrumental in improving its acceptability and understandability before using it in the ConCure-SM feasibility trial. Furthermore, our data reveal a lack of familiarity with ACP practice in the Italian context.

Postpartum relapse risk in multiple sclerosis: a systematic review and meta-analysis.

The influence of pregnancy on the course of multiple sclerosis (MS) has long been controversial. While historical evidence suggests a substantial decline in relapse rates during pregnancy followed by a rebound in the postpartum period, more recent work yielded equivocal results. We performed a systematic review and meta-analysis on data from cohort studies to determine whether women with MS experience increased relapse rates after delivery. A systematic literature search was conducted in the databases MEDLINE and Epistemonikos on the topic 'motherhood choice in MS' in March 2022. We included cohort studies assessing the association between pregnancy and MS relapse activity defined by the annualised relapse rate after 3, 6, 9 and 12 months post partum. Furthermore, information about disease-modifying therapies (DMT) and breast feeding was considered, if available. 5369 publications were identified. Of these, 93 full-text articles on MS relapse activity during the postpartum period were screened. 11 studies including 2739 pregnancies were eligible. Women with MS showed a significantly increased relapse rate in the first 6 months post partum, compared with preconception with the incidence rate ratio (IRR) almost doubled in the first 3 months post partum (1.87, 95% CI 1.40 to 2.50). However, at 10-12 months post partum, the IRR decreased significantly (0.81, 95% CI 0.67 to 0.98). Subanalysis on influencing parameters suggested that preconceptional DMTs (IRR for highly-effective DMTs 2.76, 95% CI 1.34 to 5.69) and exclusive breast feeding (risk ratio 0.39, 95% CI 0.18 to 0.86) significantly influenced postpartum relapse risk. Increased postpartum annualised relapse rate and possible modifiers should be considered in counselling women with MS who are considering pregnancy.

Improvements in quality of life over 2 years with cladribine tablets in people with relapsing multiple sclerosis: The CLARIFY-MS study.

BACKGROUND: Multiple sclerosis (MS) negatively affects health-related quality of life (HRQoL). OBJECTIVE: To evaluate HRQoL in people with highly active relapsing MS treated with cladribine tablets (CladT; 3.5 mg/kg cumulative dose over 2 years) in CLARIFY-MS. METHODS: Changes in the MS quality of life (MSQoL)-54 scores were analysed using a repeated mixed-effects linear model. Subgroup analyses were performed for participants who were pretreatment-naïve and those pretreated with disease-modifying therapies (DMTs) before initiating CladT. Safety and tolerability of CladT were also assessed. RESULTS: MSQoL-54 physical (mean change = 4.86; 95% confidence interval (CI) = 3.18, 6.53) and mental health (4.80; 95% CI = 3.13, 6.46) composite scores (primary endpoints) showed significant improvement at Month 24 versus Baseline (p < 0.0001). Changes in the MSQoL-54 scores were consistent across the pretreatment-naïve and DMT-pretreated subgroups. No new severe or opportunistic infections occurred. Most post-baseline lymphopenia events were Grade 1-2 in severity. Transient Grade-3 lymphopenia was observed in 19.7% (95/482) of participants. Grade-4 lymphopenia was not observed. CONCLUSIONS: CladT treatment significantly improved the mean MSQoL-54 physical and mental health composite scores over 2 years. CladT efficacy in HRQoL, relapse rates and Expanded Disability Status Scale scores demonstrates its multidimensional effects in MS treatment.

Applying multidimensional computerized adaptive testing to the MSQOL-54: a simulation study.

BACKGROUND: The Multiple Sclerosis Quality of Life-54 (MSQOL-54) is one of the most commonly-used MS-specific health-related quality of life (HRQOL) measures. It is a multidimensional, MS-specific HRQOL inventory, which includes the generic SF-36 core items, supplemented with 18 MS-targeted items. Availability of an adaptive short version providing immediate item scoring may improve instrument usability and validity. However, multidimensional computerized adaptive testing (MCAT) has not been previously applied to MSQOL-54 items. We thus aimed to apply MCAT to the MSQOL-54 and assess its performance. METHODS: Responses from a large international sample of 3669 MS patients were assessed. We calibrated 52 (of the 54) items using bifactor graded response model (10 group factors and one general HRQOL factor). Then, eight simulations were run with different termination criteria: standard errors (SE) for the general factor and group factors set to different values, and change in factor estimates from one item to the next set at < 0.01 for both the general and the group factors. Performance of the MCAT was assessed by the number of administered items, root mean square difference (RMSD), and correlation. RESULTS: Eight items were removed due to local dependency. The simulation with SE set to 0.32 (general factor), and no SE thresholds (group factors) provided satisfactory performance: the median number of administered items was 24, RMSD was 0.32, and correlation was 0.94. CONCLUSIONS: Compared to the full-length MSQOL-54, the simulated MCAT required fewer items without losing precision for the general HRQOL factor. Further work is needed to add/integrate/revise MSQOL-54 items in order to make the calibration and MCAT performance efficient also on group factors, so that the MCAT version may be used in clinical practice and research.

Italian cross-cultural adaptation of the patient-reported outcome measure of ataxia.

BACKGROUND: The patient-reported outcome measure of ataxia (PROM-Ataxia) is the first patient-reported questionnaire specifically developed for use in patients with cerebellar ataxia. The scale was recently designed and validated in English language, and it consists of 70 items encompassing all aspects associated with the patient experience, including physical and mental health and their consequences on activities of daily living. The aim of the study was to translate and culturally adapt into Italian the PROM-Ataxia questionnaire, before assessing its psychometric properties. METHODS: We translated and culturally adapted into Italian the PROM-Ataxia following the ISPOR TCA Task Force guidelines. The questionnaire was field tested via cognitive interviews with users. RESULTS: The Italian patients found that the questionnaire was complete, and no significant contents related to the physical, mental, and functional dimensions were missing. Some items were found redundant or ambiguous. Most of the identified issues pertained to semantic equivalence, and a few to conceptual and normative equivalence, while the questionnaire did not contain any idiomatic expression. CONCLUSIONS: The translation and cultural adaptation of the PROM-Ataxia questionnaire in the Italian patient population represent the pre-requisite for the subsequent psychometric validation of the scale. This instrument may be valuable for cross-country comparability that would allow the merging of the data in collaborative multinational research studies.

Health professional involvement in the formulation of research questions: findings from the Italian guideline on palliative care in adults with glioma.

BACKGROUND: In 2017, the European Association of Neuro-Oncology (EANO) published the guideline for palliative care in adults with glioma. The Italian Society of Neurology (SIN), the Italian Society for Palliative Care (SICP), and the Italian Association for Neuro-Oncology (AINO) joined forces to update the guideline, and adapt it to the Italian context. AIM: We involved patients, caregivers, and (herein presented) healthcare professionals (HPs) in the formulation of the guideline clinical questions. DESIGN AND PARTICIPANTS: Online survey of Italian HPs experienced in the care of patients with glioma. Participants rated the importance of 14 pre-specified intervention topics on a 0/10 scale and gave their free comments. RESULTS: Of 244 participants, 149 (61%) were palliative medicine (PM) HPs and 95 Neuro HPs. Their mean age was 48.9 years, 63% were women, and 48% had over 12 years of experience in the care of glioma patients. Physicians were 68%, followed by nurses (28%), psychologists (7%), therapists (3%), and social workers (2%). Most HPs rated the pre-specified topics as important (score ≥ 7) or critical (score ≥ 9), with some differences between PM and Neuro HP groups. There were 58 free comments: 46 (78%) on nine pre-specified topics, and 13 on four new topics, three of which were guideline-pertinent ("caregiver's support and education"; "family physician's training in neuro-oncology"; and "PM HPs' training in neuro-oncology"). CONCLUSIONS: Participation in the survey was high and information-rich, between-group rating differences reflecting HP background. Participants endorsed the 14 intervention topics devised by the guideline panel and identified three additional topics.

Patient and carer involvement in the formulation of research questions: findings from the Italian guideline on palliative care in adults with glioma.

BACKGROUND: In 2017, the European Association for Neuro-Oncology (EANO) published the guideline for palliative care (PC) in adults with glioma. The Italian Society of Neurology (SIN), the Italian Association for Neuro-Oncology (AINO), and the Italian Society for Palliative Care (SICP) joined forces to update and adapt this guideline to the Italian context and aimed to involve patients and carers in the formulation of the clinical questions. METHODS: During semi-structured interviews with glioma patients and focus group meetings (FGMs) with family carers of deceased patients, participants rated the importance of a set of pre-specified intervention topics, shared their experience, and suggested additional topics. Interviews and FGMs were audio-recorded, transcribed, coded, and analyzed (framework and content analysis). RESULTS: We held 20 interviews and five FGMs (28 carers). Both parties considered the pre-specified topics as important, chiefly information/communication, psychological support, symptoms management, and rehabilitation. Patients aired the impact of focal neurological and cognitive deficits. Carers reported difficulties in dealing with patient's behavior and personality changes and appreciated the preservation of patient's functioning via rehabilitation. Both affirmed the importance of a dedicated healthcare path and patient's involvement in the decision-making process. Carers expressed the need to be educated and supported in their caregiving role. CONCLUSIONS: Interviews and FGMs were well informative and emotionally challenging. Both parties confirmed the importance of the pre-specified topics, and carers suggested one additional topic: education/support to caregivers. Our findings strengthen the importance of a comprehensive care approach and of addressing the needs of both patients and their family carers.

Diagnosis and treatment of Chiari malformation type 1 in children: the International Consensus Document.

BACKGROUND: Chiari malformation type 1 (CM1) is a rare condition where agreed classification and treatment are still missing. The goal of this study is to achieve a consensus on the diagnosis and treatment of CM1 in children. METHODS: A multidisciplinary panel formulated 57 provisional statements based on a review of the literature. Thirty-four international experts (IE) participated in a Delphi study by independently rating each statement on a 4-point Likert scale ("strongly disagree," "disagree," "agree," "strongly agree"). Statements that were endorsed ("agree" or "strongly agree") by < 75% of raters were re-formulated, or new statements were added, and another Delphi round followed (up to a maximum of three). RESULTS: Thirty-five IE were contacted and 34 agreed to participate. A consensus was reached on 30/57 statements (52.6%) after round 1. Three statements were added, and one removed. After round 2, agreement was reached on 56/59 statements (94.9%). Finally, after round 3, which took place during the 2019 Chiari Consensus Conference (Milan, Italy), agreement was reached on 58/59 statements (98.3%) about four main sections (Definition and Classification, Planning, Surgery, Isolated Syringomyelia). Only one statement did not gain a consensus, which is the "definition of radiological failure 24 month post-surgery." CONCLUSIONS: The consensus document consists of 58 statements (24 on diagnosis, 34 on treatment), serving clinicians and researchers following children with CM1. There is a clear need for establishing an international network and registry and to promote collaborative studies to increase the evidence base and optimize the long-term care of this patient population.

Diagnosis and treatment of Chiari malformation and syringomyelia in adults: international consensus document.

BACKGROUND: Syringomyelia and Chiari malformation are classified as rare diseases on Orphanet, but international guidelines on diagnostic criteria and case definition are missing. AIM OF THE STUDY: to reach a consensus among international experts on controversial issues in diagnosis and treatment of Chiari 1 malformation and syringomyelia in adults. METHODS: A multidisciplinary panel of the Chiari and Syringomyelia Consortium (4 neurosurgeons, 2 neurologists, 1 neuroradiologist, 1 pediatric neurologist) appointed an international Jury of experts to elaborate a consensus document. After an evidence-based review and further discussions, 63 draft statements grouped in 4 domains (definition and classification/planning/surgery/isolated syringomyelia) were formulated. A Jury of 32 experts in the field of diagnosis and treatment of Chiari and syringomyelia and patient representatives were invited to take part in a three-round Delphi process. The Jury received a structured questionnaire containing the 63 statements, each to be voted on a 4-point Likert-type scale and commented. Statements with agreement <75% were revised and entered round 2. Round 3 was face-to-face, during the Chiari Consensus Conference (Milan, November 2019). RESULTS: Thirty-one out of 32 Jury members (6 neurologists, 4 neuroradiologists, 19 neurosurgeons, and 2 patient association representatives) participated in the consensus. After round 2, a consensus was reached on 57/63 statements (90.5%). The six difficult statements were revised and voted in round 3, and the whole set of statements was further discussed and approved. CONCLUSIONS: The consensus document consists of 63 statements which benefited from expert discussion and fine-tuning, serving clinicians and researchers following adults with Chiari and syringomyelia.

Identifying Progression in Multiple Sclerosis: New Perspectives.

The identification of progression in multiple sclerosis is typically retrospective. Given the profound burden of progressive multiple sclerosis, and the recent development of effective treatments for these patients, there is a need to establish measures capable of identifying progressive multiple sclerosis early in the disease course. Starting from recent pathological findings, this review assesses the state of the art of potential measures able to predict progressive multiple sclerosis. Future promising biomarkers that might shed light on mechanisms of progression are also discussed. Finally, expansion of the concept of progressive multiple sclerosis, by including an assessment of cognition, patient-reported outcomes, and comorbidities, is considered. ANN NEUROL 2020;88:438-452.

Viability of a MSQOL-54 general health-related quality of life score using bifactor model.

BACKGROUND: MSQOL-54 is a multidimensional, widely-used, health-related quality of life (HRQOL) instrument specific for multiple sclerosis (MS). Findings from the validation study suggested that the two MSQOL-54 composite scores are correlated. Given this correlation, it could be assumed that a unique total score of HRQOL may be calculated, with the advantage to provide key stakeholders with a single overall HRQOL score. We aimed to assess how well the bifactor model could account for the MSQOL-54 structure, in order to verify whether a total HRQOL score can be calculated. METHODS: A large international database (3669 MS patients) was used. By means of confirmatory factor analysis, we estimated a bifactor model in which every item loads onto both a general factor and a group factor. Fit of the bifactor model was compared to that of single and two second-order factor models by means of Akaike information and Bayesian information criteria reduction. Reliability of the total and subscale scores was evaluated with Mc Donald's coefficients (omega, and omega hierarchical). RESULTS: The bifactor model outperformed the two second-order factor models in all the statistics. All items loaded satisfactorily (≥ 0.40) on the general HRQOL factor, except the sexual function items. Omega coefficients for total score were very satisfactory (0.98 and 0.87). Omega hierarchical for subscales ranged between 0.22 to 0.57, except for the sexual function (0.70). CONCLUSIONS: The bifactor model is particularly useful when it is intended to acknowledge multidimensionality and at the same time take account of a single general construct, as the HRQOL related to MS. The total raw score can be used as an estimate of the general HRQOL latent score.

The management of Chiari malformation type 1 and syringomyelia in children: a review of the literature.

In anticipation of the "Chiari and Syringomyelia Consensus Conference" held in Milan in 2019, we performed a systematic literature review on the management of Chiari malformation type 1 (CM1) and syringomyelia (Syr) in children.We aimed to summarize the available evidence and identify areas where consensus has not been reached and further research is needed.In accordance with PRISMA guidelines, we formulated seven questions in Patients-Interventions-Comparators-Outcomes (PICO) format. Six PICOs concerned CM1 children with/without additional structural anomalies (Syr, craniosynostosis, hydrocephalus, tethered cord, and cranio-vertebral junction anomalies), and one PICO Syr without CM1. We searched Medline, Embase, Cochrane, and NICE databases from January 1, 1999, to May 29, 2019. Cohort studies, controlled and randomized clinical trials (CCTs, RCTs), and systematic reviews were included, all pertinent only to patients ≤ 18 years of age.For CM1, 3787 records were found, 460 full texts were assessed and 49 studies (46 cohort studies, one RCT, and two systematic reviews) were finally included. For Syr, 376 records were found, 59 full texts were assessed, and five studies (one RCT and four cohort studies) were included. Data on each PICO were synthetized narratively due to heterogeneity in the inclusion criteria, outcome measures, and length of follow-up of the included studies.Despite decades of experience on CM1 and Syr management in children, the available evidence remains limited. Specifically, there is an urgent need for collaborative initiatives focusing on the adoption of shared inclusion criteria and outcome measures, as well as rigorous prospective designs, particularly RCTs.

Assessing measurement invariance of MSQOL-54 across Italian and English versions.

PURPOSE: The Multiple Sclerosis Quality of Life-54 (MSQOL-54) is a specific multiple sclerosis (MS) health-related quality of life inventory consisting of 52 items organized into 12 subscales plus two single items. No study was found in literature assessing its measurement invariance across language versions. We investigated whether MSQOL-54 items provide unbiased measurements of underlying constructs across Italian and English versions. METHODS: Three constrained levels of measurement invariance were evaluated: configural invariance where equivalent numbers of factors/factor patterns were required; metric invariance where equivalent factor loadings were required; and scalar invariance where equivalent item intercepts between groups were required. Comparative fit index (CFI), root mean square error of approximation (RMSEA), and standardized root mean square residual (SRMR) fit indices and their changes between nested models were used to assess tenability of invariance constraints. RESULTS: Overall, the dataset included 3669 MS patients: 1605 (44%) Italian, mean age 41 years, 62% women, 69% with mild level of disability; 2064 (56%) English-speaking (840 [41%] from North America, 797 [39%] from Australasia, 427 [20%] from UK and Ireland), mean age 46 years, 83% women, 54% with mild level of disability. The configural invariance model showed acceptable fit (RMSEA = 0.052, CFI = 0.904, SRMR = 0.046); imposing loadings and intercepts equality constraints produced negligible worsening of fit (ΔRMSEA < 0.001, ΔCFI = - 0.002, ΔSRMR = 0.002 for metric invariance; ΔRMSEA = 0.003, ΔCFI = - 0.013, ΔSRMR = 0.003 for scalar invariance). CONCLUSIONS: These findings support measurement invariance of the MSQOL-54 across the two language versions, suggesting that the questionnaire has the same meaning and the same measurement paramaters in the Italian and English versions.

Reliability and acceptability of the Multiple Sclerosis Quality of Life-29 questionnaire in an English-speaking cohort.

BACKGROUND: Multiple Sclerosis Quality-of-Life Questionnaire-54 (MSQoL-54) is a disease-specific instrument for assessing health-related quality of life (HRQoL). Due to the number of items, the time taken to complete it is long. A shorter 29-item version, Multiple Sclerosis Quality-of-Life Questionnaire-29 (MSQoL-29) is yet to be evaluated in English. OBJECTIVE: To assess reliability and acceptability of English version of MSQoL-29. METHODS: Among 100 participants with MS who first completed both MSQoL-54 and MSQoL-29, 91 completed MSQoL-29 after 4-8 weeks. We looked for internal consistency (Cronbach's alpha), acceptability, reliability (intraclass correlation coefficients (ICCs)) and agreement (Bland-Altman plots). RESULTS: ICCs were strongly positive between MSQoL-54 and MSQoL-29 (Physical Health Composite (PHC) -ICC = 0.914, confidence interval (CI) = 0.872-0.942; Mental Health Composite (MHC) - ICC = 0.875, CI = 0.814-0.916) and between the two MSQoL-29 (PHC - ICC = 0.970, CI = 0.955-0.980; MHC - ICC = 0.937, CI = 0.904-0.958). On Bland-Altman plots, the MSQoL-29 scores of 95% of participants during two visits were within the limits of agreement (LOAs). Time taken to complete MSQoL-29 was 7.2 ± 2.9 minutes and MSQoL-54 was 19.79 ± 5.4 minutes (p = 0.0001). CONCLUSION: MSQoL-29 has good test-retest reliability in English-speaking population and was quicker to complete.

eMSQOL-29: Prospective validation of the abbreviated, electronic version of MSQOL-54.

BACKGROUND: We recently devised a shortened version of the 54-item Multiple Sclerosis Quality of Life (MSQOL-54) in paper (MSQOL-29, consisting of 25 items forming 7 subscales and 4 single items, and one filter question for 3 'sexual function' items) and electronic format (eMSQOL-29). OBJECTIVES: To prospectively assess eMSQOL-29 psychometric properties, acceptability/equivalence versus MSQOL-29. METHODS: Multiple sclerosis (MS) patients ( n = 623; Expanded Disability Status Scale (EDSS) range 0.0-9.0) completed eMSQOL-29, Hospital Anxiety and Depression Scale, Functional Assessment of MS (FAMS), European Quality of life Five Dimensions-3L, and received EDSS and Symbol Digit Modalities Test (SDMT). Equivalence versus MSQOL-29 was assessed in 242 patients (randomized cross-over design). RESULTS: 'Sexual function' items were filtered out by 273 patients (47%). No multi-item scale had floor effect, while five had ceiling effect. Cronbach's alpha range was 0.88-0.90. Confirmatory factor analysis showed good overall fit and the two-factor solution for composite scores was confirmed. Criterion validity was sub-optimal for 'cognitive function' (vs SDMT, r = 0.25) and 'social function' (vs FAMS social function, r = 0.38). eMSQOL-29 equivalence was confirmed and its acceptability was good. CONCLUSION: eMSQOL-29 showed good internal consistency, factor structure and no floor effect, while most subscales had some ceiling effect. Criterion validity was sub-optimal for two subscales. Equivalence and acceptability were good.

Randomized controlled trial of a home-based palliative approach for people with severe multiple sclerosis.

BACKGROUND: Evidence on the efficacy of palliative care in persons with severe multiple sclerosis (MS) is scarce. OBJECTIVE: To assess the efficacy of a home-based palliative approach (HPA) for adults with severe MS and their carers. METHODS: Adults with severe MS-carer dyads were assigned (2:1 ratio) to either HPA or usual care (UC). At each center, a multi-professional team delivered the 6-month intervention. A blind examiner assessed dyads at baseline, 3 months, and 6 months. Primary outcome measures were Palliative care Outcome Scale-Symptoms-MS (POS-S-MS) and Schedule for the Evaluation of Individual Quality of Life-Direct Weighting (SEIQoL-DW, not assessed in severely cognitively compromised patients). RESULTS: Of 78 dyads randomized, 76 (50 HPA, 26 UC) were analyzed. Symptom burden (POS-S-MS) significantly reduced in HPA group compared to UC ( p = 0.047). Effect size was 0.20 at 3 months and 0.32 at 6 months, and statistical significance was borderline in per-protocol analysis ( p = 0.062). Changes in SEIQoL-DW index did not differ in the two groups, as changes in secondary patient and carer outcomes. CONCLUSION: HPA slightly reduced symptoms burden. We found no evidence of HPA efficacy on patient quality of life and on secondary outcomes.

Information provision for people with multiple sclerosis.

BACKGROUND: People with multiple sclerosis (MS) are confronted with a number of important uncertainties concerning many aspects of the disease. These include diagnosis, prognosis, disease course, disease-modifying therapies, symptomatic therapies, and non-pharmacological interventions, among others. While people with MS demand adequate information to be able to actively participate in medical decision making and to self manage their disease, it has been shown that patients' disease-related knowledge is poor, therefore guidelines recommend clear and concise high-quality information at all stages of the disease. Several studies have outlined communication and information deficits in the care of people with MS. However, only a few information and decision support programmes have been published. OBJECTIVES: The primary objectives of this updated review was to evaluate the effectiveness of information provision interventions for people with MS that aim to promote informed choice and improve patient-relevant outcomes, Further objectives were to evaluate the components and the developmental processes of the complex interventions used, to highlight the quantity and the certainty of the research evidence available, and to set an agenda for future research. SEARCH METHODS: For this update, we searched the Cochrane Multiple Sclerosis and Rare Diseases of the Central Nervous System Group Specialised Register, which contains trials from CENTRAL (the Cochrane Library 2017, Issue 11), MEDLINE, Embase, CINAHL, LILACS, PEDro, and clinical trials registries (29 November 2017) as well as other sources. We also searched reference lists of identified articles and contacted trialists. SELECTION CRITERIA: Randomised controlled trials (RCTs), cluster-randomised controlled trials, and quasi-randomised trials comparing information provision for people with MS or suspected MS (intervention groups) with usual care or other types of information provision (control groups) were eligible. DATA COLLECTION AND ANALYSIS: Two review authors independently assessed the retrieved articles for relevance and methodological quality and extracted data. Critical appraisal of studies addressed the risk of selection bias, performance bias, attrition bias, and detection bias. We contacted authors of relevant studies for additional information. MAIN RESULTS: We identified one new RCT (73 participants), which when added to the 10 previously included RCTs resulted in a total of 11 RCTs that met the inclusion criteria and were analysed (1387 participants overall; mean age, range: 31 to 51; percentage women, range: 63% to 100%; percentage relapsing-remitting MS course, range: 45% to 100%). The interventions addressed a variety of topics using different approaches for information provision in different settings. Topics included disease-modifying therapy, relapse management, self care strategies, fatigue management, family planning, and general health promotion. The active intervention components included decision aids, decision coaching, educational programmes, self care programmes, and personal interviews with physicians. All studies used one or more components, but the number and extent differed markedly between studies. The studies had a variable risk of bias. We did not perform meta-analyses due to marked clinical heterogeneity. All five studies assessing MS-related knowledge (505 participants; moderate-certainty evidence) detected significant differences between groups as a result of the interventions, indicating that information provision may successfully increase participants' knowledge. There were mixed results on decision making (five studies, 793 participants; low-certainty evidence) and quality of life (six studies, 671 participants; low-certainty evidence). No adverse events were detected in the seven studies reporting this outcome. AUTHORS' CONCLUSIONS: Information provision for people with MS seems to increase disease-related knowledge, with less clear results on decision making and quality of life. The included studies in this review reported no negative side effects of providing disease-related information to people with MS. Interpretation of study results remains challenging due to the marked heterogeneity of interventions and outcome measures.

Biomarkers predict outcome in Charcot-Marie-Tooth disease 1A.

BACKGROUND: Charcot-Marie-Tooth disease type 1A (CMT1A) is the most common inherited neuropathy, a debilitating disease without known cure. Among patients with CMT1A, disease manifestation, progression and severity are strikingly variable, which poses major challenges for the development of new therapies. Hence, there is a strong need for sensitive outcome measures such as disease and progression biomarkers, which would add powerful tools to monitor therapeutic effects in CMT1A. METHODS: We established a pan-European and American consortium comprising nine clinical centres including 311 patients with CMT1A in total. From all patients, the CMT neuropathy score and secondary outcome measures were obtained and a skin biopsy collected. In order to assess and validate disease severity and progression biomarkers, we performed qPCR on a set of 16 animal model-derived potential biomarkers in skin biopsy mRNA extracts. RESULTS: In 266 patients with CMT1A, a cluster of eight cutaneous transcripts differentiates disease severity with a sensitivity and specificity of 90% and 76.1%, respectively. In an additional cohort of 45 patients with CMT1A, from whom a second skin biopsy was taken after 2-3 years, the cutaneous mRNA expression of GSTT2, CTSA, PPARG, CDA, ENPP1 and NRG1-Iis changing over time and correlates with disease progression. CONCLUSIONS: In summary, we provide evidence that cutaneous transcripts in patients with CMT1A serve as disease severity and progression biomarkers and, if implemented into clinical trials, they could markedly accelerate the development of a therapy for CMT1A.
