Impact of multiple sclerosis comorbidities on quality of life and job activity

Background: Multiple sclerosis (MS) is frequently accompanied by comorbid conditions. Objectives: This study aimed to determine the prevalence of key comorbid conditions in people with multiple sclerosis (pwMS) and assess their impact on quality of life and work-related activities. Methods: A cross-sectional study involving 755 pwMS from two third-level Italian MS centers was conducted. Comorbidities were identified from medical records, and quality of life was assessed using the EQ-5D-3L questionnaire. Work-related challenges were evaluated using the Multiple Sclerosis Questionnaire for Job Difficulties (MSQ-Job). Results: 53.8% of pwMS had at least one comorbidity. Hypertension, depression, and anxiety were the most prevalent. Comorbidity presence was associated with reduced quality of life scores in almost all EQ-5D-3L domains and greater job difficulties in all but one MSQ-Job domain. Conclusion: Comorbidities in pwMS are prevalent and have a profound influence on quality of life and work-related activities. This comprehensive study offers new insights into the role of comorbidities in MS within the Italian context, emphasizing the need for a multidisciplinary approach in MS management. Further research is crucial to deepen our understanding of these findings in the broader Italian MS community.

Can Voice Parameters Provide Cutoff Values to Predict Dysphagia in Individuals with Multiple Sclerosis?

In dysphagia assessment, along with well-defined measurements and signs, voice parameters can potentially support clinical decision as a marker, but more evidence is needed. This study aims to determine the voice parameters that can predict the risk of dysphagia and to determine optimal cutoff values in individuals with multiple sclerosis (IwMS). Seventy-six adults participated in the study, including 39 IwMS and 37 healthy individuals (HI). The study used the Dysphagia in Multiple Sclerosis Questionnaire (DYMUS), Gugging Swallowing Screen (GUSS), and Voice Handicap Index (VHI-10) and recorded voice samples using Praat programme. Voice recordings were taken pre- and post-swallowing. The voice parameters analysed are fundamental frequency (F0), standard deviation F0 (SD F0), jitter (local), shimmer (local), and harmonic-to-noise ratio (HNR). Roc analysis was performed to examine the diagnostic accuracy performance of the risk for dysphagia/penetration. The parameters of IwMS pre-swallowing differed significantly from those of HI on the VHI-10, DYMUS, GUSS scores, and jitter (local), shimmer (local), and HNR. IwMS but not HI exhibited significant differences in shimmer (local) and HNR between the pre- and post-swallowing measurements. In IwMS, GUSS revealed significant differences in shimmer (local) pre- and post-swallowing between the groups with and without dysphagia/penetration. In the ROC analysis results, the area under the curve (AUC) for shimmer (local) pre-swallowing was 73.1% (cutoff = 1.69); post-swallowing, it was 78.6% (cutoff = 1.57). In conclusion, IwMS can be associated with differences in shimmer (local) and HNR parameters, low quality of life-related to voice, and dysphagia/penetration risk. The AUC values for shimmer (local) in IwMS pre- and post-swallowing may help to strengthen diagnostic decisions of dysphagia risk.

Drooling may be Associated with Dysphagia Symptoms in Multiple Sclerosis

During the process of the multiple sclerosis (MS), persons with multiple sclerosis (PwMS) may experience drooling (sialorrhea) issues that are frequently disregarded. The exact cause of drooling in PwMS is poorly understood. This study aims to assess potential risk factors for drooling seen in PwMS. The study included 20 PwMS with drooling and 19 PwMS without drooling. The participants’ sociodemographic data and clinical parameters were noted. To evaluate dysphagia, fatigue, and hypersalivation, the Dysphagia in Multiple Sclerosis Questionnaire (DYMUS), the Fatigue Severity Scale (FSS), and objective saliva flow rate measurement with cottons placed in Stensen ducts and under the tongue (swab test) were used, respectively. The study employed univariate and multivariate logistic regression models to identify the risk factors linked to drooling. Gender, age, disease duration, MS type, and Expanded Disability Status Scale scores did not differ between the two groups. There was a significant increase in the DYMUS and submandibular/sublingual (SM/SL) saliva flow rate values in PwMS with drooling (p = 0.009 and p = 0.019, respectively). However, in our study, hypersalivation was not observed in PwMS with or without drooling. In the univariate model, DYMUS, SM/SL saliva flow rate, and FSS were found to be risk factors for drooling in PwMS. But only DYMUS was shown to be a significant risk factor in the multivariate model obtained by the backward (Wald) elimination method (p = 0.023). Finally, our research is the first to demonstrate the relationship between drooling and the presence of dysphagia symptoms in PwMS. This is a very important study to determine the nature of drooling in PwMS. This finding shows that our study will serve as a reference for choosing the best method for drooling treatment.

Validity and reliability of the Persian version of Recce stigma scale in people with multiple sclerosis and its impact on quality of life.

There is often a fear of social stigma experienced by people with multiple sclerosis (pwMS), which negatively impacts the quality of their lives (QoL). Currently, no Persian-validated questionnaire is available to assess this issue in pwMS. This study aimed to assess the validaty and reliability of the Persian version of Reece Stigma Scale Multiple Sclerosis (RSS-MS) questionnaire for pwMS. This cross-sectional was conducted between January and February 2023 in Isfahan, Iran. The demographic and clinical information and the RSS-MS and Multiple Sclerosis Impact Scale-29 (MSIS-29) questionnaires were recorded from pwMS. The content validity index (CVI) and content validity ratio (CVR) have been used to evaluate validity. To identify the factors supporting the MS-related stigma, an exploratory factor analysis (EFA) was conducted. The present study recruited 194 pwMS. Based on factor analysis, only two factors had eigenvalues ≥ 1.0 and exhibited high internal consistency. The Cronbach's α coefficient for internal consistency of the RSS-MS scale was 0.822. More evidence for the construct validity suggested that having higher levels of stigma is significantly correlated with psychological (r = 0.468, p-value < 0.001) and physical dimensions (r = 0.585, p-value < 0.001) of MSIS-29. Expanded Disability Status Scale, disease duration, and treatment duration did not show a significant correlation with stigma (p-value > 0.05). This study indicated that the modified version of the RSS-MS scale in the Persian language showed acceptable validity and reliability for evaluating the stigma among Persian pwMS. Furthermore, this study emphasizes the cruciality of monitoring and addressing stigma among pwMS, as it can potentially enhance medical, psychological, physical, and QoL outcomes.

Questionnaires for arm function assessment in patients with multiple sclerosis

Arm dysfunction is one of the disabling manifestations of multiple sclerosis (MS), especially in later stages of the disease. Assessment of the functioning of the upper limbs is necessary to objectify the course of MS, determine the effectiveness of therapy, and individualize rehabilitation measures. The tools that assess the upper extremity dysfunction include tests and questionnaires. Questionnaires (patient-reported outcome measures) represent the special importance, since the opinions and preferences of patients themselves help to implement a patient-centered approach to treatment. The article presents a brief description of three multidimensional MS-specific and four unidimensional MS-nonspecific questionnaires that used in assessment of upper limb function in MS patients. The disease-specific unidimensional Arm Function in Multiple Sclerosis Questionnaire (AMSQ), specifically designed to assess the arm use in patients with MS, is discussed in more detail. The use of AMSQ in the Russian population is possible only after the procedure of cultural adaptation and validation of the Russian version.

Assessment of Multiple Aspects of Upper Extremity Function Independent From Ambulation in Patients With Multiple Sclerosis.

Upper extremity function (UEF) is often compromised in multiple sclerosis (MS), although its importance is regularly underrecognized relative to ambulation. We explored the concurrent presence of impairment in UEF and ambulation by examining various aspects of UEF across different levels of ambulation. The cohort consisted of 247 patients with clinically definite MS or clinically isolated syndrome according to the revised 2010 McDonald criteria. The Nine-Hole Peg Test and the Expanded Disability Status Scale were used to stratify patients into clinically different subgroups. For UEF, cerebellar function (finger-to-nose test), pyramidal function (pronator drift test), and the ability to perform a task of activities of daily living (drinking-from-cup test) were examined. Patient-reported limitations of UEF in daily life were assessed using the Arm Function in Multiple Sclerosis Questionnaire. Patients in more severely impaired ambulation groups displayed poorer performance on all UEF measures. Although most patients had normal to mild (n = 147) or moderate (n = 46) ambulatory impairment, 87.7% exhibited some level of UEF impairment as defined using the Nine-Hole Peg Test. Most patients had mild UEF impairment (n = 174), accounting for the largest proportion in all ambulation groups (51.9%-77.8%). A distinct pattern of impairment was found for ambulation and multiple aspects of UEF. Independent assessment of multiple aspects of disability may be helpful in treatment decision-making and could support the development of rehabilitation strategies that specifically target UEF impairment.

Validation of the Spanish version of DYsphagia in MUltiple Sclerosis questionnaire (DYMUS).

Dysphagia is a common symptom in multiple sclerosis that can occur even early in the disease course and can lead to serious complications. Early recognition and treatment can promote comfort, safety and optimal nutritional status. Few dysphagia rating scales are available in Spanish. The aim of this study was to translate the Dysphagia in Multiple Sclerosis Questionnaire (DYMUS) into Spanish and to validate it. Forward and backward translation method was used to translate the original English version of DYMUS into Spanish. A pilot-study with 10 PwMS was carried on in order to improve the intelligibility of the instrument, comprehensibility and content validity of the questionnaire. The questionnaire was filled out by 100 PwMS who were asked a dichotomous question on their swallowing ("Do you have swallowing troubles?"). Descriptive data are presented as median and quartiles for continuous variables and frequency and percentage for categorical ones. Internal consistency reliability was estimated by Cronbach's alfa. Test-retest reliability was estimated by intraclass correlation coefficient. Concurrent validity with a speech and language therapy assessment (SLT-A) was measured with the weighted kappa statistic for the concordance for both dysphagia type and degree categories. Confirmatory factor analysis by means of structural equation models was used to verify the two-factor (solids and liquids) structure of the DYMUS questionnaire. As the goodness of fit evaluation was poor, an additional exploratory factor analysis was carried out. Internal consistency was high. The globus sensation question and the weight loss questions (item 3 and 10) are the least specific with dysphagia symptomatology so they are worst correlated with the sum of the others (item-rest correlation, 0.243 and 0.248, respectively). The test-retest reliability of the DYMUS among 40 patients using ICC was 0.75 (95% CI 0.57 - 0.86). Concurrent validity with SLT-A was poor (weighted kappa 0.37 for dysphagia type and 0.38 for dysphagia degree). The DYMUS questionnaire detected three times more dysphagia (53% versus 17%) than the dichotomous question. Confirmatory factors analysis failed to confirm the bidimensional structure (solid and liquid items) often reported in other validation studies. The subsequent exploratory factor analysis also identified two factors, but with poor interpretability. DYMUS-SP scale is not a sufficiently useful scale to detect dysphagia in PwMS due to the poor concurrent validity and the probable overdiagnosis of the condition; however, it can be helpful as a screening tool when combined with other measures.

Feasibility and usability of a new home-based immersive virtual reality headset-based dexterity training in multiple sclerosis.

Impaired manual dexterity is frequent and disabling in patients with multiple sclerosis (MS), affecting activities of daily living and quality of life. The aim of this study was to evaluate the feasibility, usability and patient engagement/satisfaction of a home-based immersive virtual reality (VR) headset-based dexterity training in persons with multiple sclerosis (pwMS). In addition, preliminary efficacy data on the impact of this new training on manual dexterity were collected. Single arm prospective study. After a waiting period of two weeks, pwMS performed a specifically developed home-based VR headset-based dexterity training using the Oculus quest 2 for two weeks with five training sessions/week, each session for approximately 20 minutes. Primary endpoints were feasibility (measured by the adherence rate), usability (System Usability Scale, SUS) and patient engagement/satisfaction (Custom User Engagement Questionnaire, CUEQ). Secondary exploratory efficacy endpoints, measured before and after the waiting period as well as after the training intervention, were the Nine-hole-Peg-Test (9HPT), Coin rotation task (CRT), Handheld JAMAR dynamometer, Arm Function in Multiple Sclerosis Questionnaire (AMSQ) and the Multiple Sclerosis Impact Scale 29 (MSIS 29). Eleven pwMS (mean age 49 ± 10.87 SD, mean EDSS 4.28 ± 1.48 SD) participated in the study. Feasibility (adherence rate: 81.8%), usability (median SUS score 94 (IQR=78-96)) and patient engagement/satisfaction (median 8 on scale of 1-10) of the VR training was very high. In addition, the CRT for the dominant hand improved significantly after training (p=0.03). The good results on feasibility, usability, and patient engagement/satisfaction qualify this home-based immersive VR headset-based dexterity training approach for the use in home-based neurorehabilitation in pwMS. Improved fine motor skills for the dominant hand suggest preliminary efficacy, but this needs to be proven in a future randomized-controlled trials.

NUTRISEP: Assessment of the nutritional status of patients with multiple sclerosis and link to fatigue

BackgroundFatigue is a common complaint in patients with multiple sclerosis (PwMS) and reduces quality of life. Several hypotheses for the pathogenesis of fatigue in MS are proposed ranging from neurological lesions to malnutrition, but none has been conclusively validated through clinical research. ObjectivesThe goal of this study was to examine the correlation between fatigue and nutritional status and dietary habits in PwMS. MethodsThis was a cross-sectional, multicenter study conducted at 10 French MS centers and enrolling PwMS with an Expanded Disability Status Scale (EDSS) score between 0 and 7. Plasma level of albumin, magnesium, calcium, iron, vitamin D and B12 evaluated nutritional status. A semi-structured eating behavior questionnaire has been developed to evaluate dietary habits. Evaluation of fatigue used specific questionnaire (EMIF-SEP). Quality of sleep was evaluated by visual analogue scale (VAS), depression with Beck Depression Inventory (BDI-II); dysphagia by DYsphagia in MUltiple Sclerosis questionnaire (DYMUS) and taste disorders by gustometry. Association between nutritional deficiencies and different data such as socio-demographic data, disease characteristics, swallowing and taste disorders, food intake, depression and sleep quality was investigated. ResultsA total of 352 patients mean age: 48.1±10.1 years, mean duration of MS: 15.3±9.1 years and median EDSS: 4 were analyzed. Bivariate and multivariate analyses showed a statistically significant correlation between fatigue and depression and use of sleeping pills, while none of the variables related to dietary habits or nutritional status correlated significantly with fatigue. ConclusionsDietary habits and nutritional status have little impact on fatigue and general population nutrition recommendations remain the rule for PwMS. In cases of fatigue, specific attention should be paid to depression and use of sleeping pills.

Development and usability testing of your MS questionnaire: A patient-based digital tool to monitor symptoms of multiple sclerosis.

We describe the development of Your Multiple Sclerosis Questionnaire and present the real-world usability testing results of Your Multiple Sclerosis Questionnaire. The Your Multiple Sclerosis Questionnaire tool was developed in four stages to collect feedback from people living with MS (plwMS), patient organizations, and clinicians on content, format, and applicability. To assess its usability, 13 clinicians across 7 countries completed an online survey after using the tool with plwMS in a total of 261 consultations from September, 2020 to July, 2021. The initial Your Multiple Sclerosis Questionnaire version was based on findings from previous research developing MSProDiscuss™, a clinician-completed tool. Subsequently, insights from plwMS obtained during cognitive debriefing, patient councils and advisory boards led to changes including the addition of mood and sexual problems and the definition of relapse. All 13 clinicians completed the individual survey, whereas 10 clinicians completed the final survey. Clinicians "strongly agreed" or "agreed" that Your Multiple Sclerosis Questionnaire was easy to use and understand (98.5%; 257/261 patient consultations). The clinicians were willing to use the tool again with the same patient (98.1%; 256/261 patient consultations). All clinicians who completed the final survey (100%; 10/10) reported the tool to have a positive influence on their clinical practice, helped patients engage with their MS, facilitated discussion with patients, and complemented neurological assessment. Your Multiple Sclerosis Questionnaire benefits both plwMS and clinicians by facilitating a structured discussion and engaging the plwMS to self-monitor and self-manage. Your Multiple Sclerosis Questionnaire is compatible with telemedicine practice and integration of the tool into electronic health records would enable tracking of the disease evolution and individual monitoring of MS symptoms over time.

Validation of the Czech Version of the Dysphagia in Multiple Sclerosis Questionnaire (DYMUS).

Dysphagia is a common symptom of neurological disease, including multiple sclerosis (MS). The DYsphagia in MUltiple Sclerosis (DYMUS) questionnaire was developed as a screening tool for swallowing problems. The purpose of the present study was to validate the Czech version of the DYMUS questionnaire. We validated the questionnaire on a sample of 435 patients with MS and 135 healthy controls (HC) chosen by accidental sampling from larger, long-term studies conducted by the Prague MS Center. For the purposes of this study, we used both electronic (primary method of distribution) and paper-based (backup) versions of the questionnaire. The internal consistency of the whole scale was satisfactory (Cronbach’s α =0.833). The DYMUS mean score in HC was 0.215 (standard deviation [SD] = 0.776). Normative data suggested a cut-off value for dysphagia between 1 and 2 points. Principal component analysis (PCA) showed a two-factor structure of the adapted scale. However, the structure did not completely correspond to the originally proposed dimensions of dysphagia for solids and liquids; our data supported dropout of item Q10. Criterion validity was proved by the difference in dysphagia between HC and patients MS (U = 25,546, p < 0.001) and by a positive correlation with the EDSS (Kendall’s tau-b = 0.169, p < 0.001) and other patient-reported outcomes. The Czech version of the DYMUS questionnaire is a valid and reliable tool for evaluating swallowing impairment in Czech-speaking patients with MS. Moreover, the questionnaire can be administered electronically, with a paper-based backup.Supplementary InformationThe online version contains supplementary material available at 10.1007/s00455-022-10530-5.

Reliability and validity of the Turkish version of speech pathology-specific questionnaire for persons with multiple sclerosis (SMS-TR)

Purpose The aim of this study is to validate the speech pathology-specific questionnaire for persons with Multiple Sclerosis (SMS) in Turkish. Method A total of 218 participants were included in the study. The study group was composed of 104 persons diagnosed with MS, and the control group was 114 healthy participants without any neurological deficits. The translated version of the SMS was administered to all participants. Test-retest reliability, internal consistency, construct validity, floor and ceiling effects were investigated. Dysphagia in multiple sclerosis questionnaire (DYMUS) was used for criterion validity. Finally, sensitivity and specificity of the SMS-TR was calculated using a ROC curve analysis. Result SMS-TR has an excellent internal consistency (Cronbach’s alpha = 0.92). Item-total correlations range between 0.45 and 0.78. The intraclass correlation coefficient (ICC) obtained for the test-retest indicates a good level of reproducibility (ICC = 0.86). According to confirmatory factor analysis, the fit measures of the scale were found to be acceptable. A significant difference was found between the total SMS scores of the study group and the control group (20.6 ± 10.4 and 1.9 ± 2.8, P < 0.001, respectively). A statistically significant correlation was observed between SMS and DYMUS (r = 0.833, P < 0.001). There were no floor and ceiling effects found in the study group. According to the ROC curve analysis, the area under the curve of SMS–TR was 0.98. The optimal cut-off value was 8, with a sensitivity of 91.3% and a specificity of 95.6%. Conclusion SMS-TR is a valid and reliable patient-reported outcome measure suitable for the assessment of language, speech, and swallowing disorders in persons with MS. A score >8 is an indicator of language, speech, and swallowing pathology for persons.

Tablet app-based dexterity training in multiple sclerosis (TAD-MS): a randomized controlled trial

Purpose Mobile health applications (mHealth apps) may lead to health benefits. In recent years, the use of apps in multiple sclerosis (MS) has increased. Apps to train and improve dexterity in MS are scarce. This study investigated the effectiveness of a tablet app-based home-based training to improve dexterity in individuals with MS. Materials and methods In a randomized controlled trial, two standardized 4-week home-based interventions focussing on different aspects of dexterity and upper limb function were compared. Assessments were done at baseline, post-intervention and 12-week follow-up. The primary endpoint was the Arm Function in Multiple Sclerosis Questionnaire, a dexterity-related measure of patient-reported activities of daily living. Secondary endpoints were dexterous function, grip strength and health-related quality of life. Results Forty-eight individuals were randomly assigned to a tablet app-based program (n = 26) or a control strengthening exercise program (n = 22). No significant differences were found for the primary endpoint (p = 0.35). Some significant differences in favour of the app-group were found in fine coordinated finger movements and strength. No significant differences were found at the 12-week follow-up for all endpoints. Adherence in both groups was above 90%. Conclusions App-based training was not superior compared to a control strengthening exercise program concerning the arm- and hand function from the participant’s perspective. However, app-based training was found to be effective in improving specific dimensions (finger movements and strength), and can easily be applied at home. Therefore, individuals living with MS with impaired dexterity should consider app-based training. Clinical Trial Registration Clinicaltrials.gov NCT03369470.

O5-2 Tele-rehabilitation program ‘Funktionstraining-online' in people with Multiple Sclerosis - preliminary results of a first online survey

BackgroundIn 2019, the German Multiple Sclerosis (MS) Society was certified as a provider for ?Funktionstraining? (FT). FT is an exercise training program developed for people with disabilities or people at risk of disability, takes place weekly and is led by a qualified FT-therapist. It is prescribed by a physician (between 12 and 24 months) and is part of outpatient medical rehabilitation. Due to the COVID-19 pandemic, the tele-rehabilitation concept ‘Funktionstraining-online’ (FT-online) was developed for pwMS. This study examines the FT-online from a participants' point of view within an online survey.MethodsWe developed an online questionnaire that included data of sample characteristics, participants' experiences with FT-online in terms of usability and training content. Further, the survey captured the quality of FT-online and the FT-therapist and compared carefully FT-online with face-to-face training. The standardised questionnaires Self-Efficacy Scale - Short Form (ASKU), the Multiple Sclerosis Questionnaire for Physiotherapists MSQPT and the Fatigue-Questionnaire (WeiMuS) were included. The 103 interviewed people with MS (pwMS) participated in FT-online at least for three months.ResultsData analyses are in process. The response rate was 75% (n = 78). The analysed sample is 53.4±8.1 years old with a disease duration of 18±8.7 years (male=7, female=71). Preliminary results in the ASKU certify a low self-efficacy in the sample (2.25 ±0.67). Qualitative results show the advantages for FT-online in the independence of mobility and infrastructure, flexibility, compatibility within job and family, group feeling in times of social distancing and an increase in quality of life. The disadvantages described by the sample are mainly technical problems and lack of socialising. 35% (n = 27) participants experienced both: FT-online and face-to-face. 44.4% (n = 12) of this sample prefer FT-online, 33.3% (n = 9) prefer the face-to-face training course and 22.2% (n = 6) rate both kinds of training equal.ConclusionsThe implementation of FT-online was an important step to ensure the exercise-related physical activity in pwMS during the COVID-19 pandemic. The descriptive analyses show high potential for FT-online training in pwMS. We are aware of the bias in current data, because of the pandemic situation both the free choice of FT-offers and the pandemic circumstances held influence in study outcomes. First results lead to the conclusion that FT-online may be beneficial for a broad range of persons with neurologic diseases, movement disorders and fatigue episodes and should be considered for future medical rehabilitation.

Cross-sectional and longitudinal correlations between the Arm Function in Multiple Sclerosis Questionnaire (AMSQ) and other outcome measures in multiple sclerosis

BackgroundThe Arm Function in Multiple Sclerosis Questionnaire (AMSQ) is the first validated disease specific patient-reported outcome measure (PROM) designed to assess upper extremity function in patients with multiple sclerosis (MS). ObjectiveTo determine correlations between the AMSQ and established physician- and performance based outcome measures. MethodsIn a cross-sectional cohort of 533 patients correlations between the AMSQ and the Expanded Disability Status Scale (EDSS), its functional systems, the 9-Hole Peg Test (9-HPT) and the Timed-25 Foot Walk (T25FW) were determined. Subgroup analyses were performed as well. Also, correlations were determined in 110 of 533 patients with available longitudinal data. ResultsStrongest correlations were found in the cross-sectional cohort between the AMSQ and the EDSS (β 0.60, p<.001), the 9-HPT dominant hand (β 0.52, p<.001) and 9-HPT non-dominant hand (β 0.46, p<.001), the Pyramidal (β 0.57 p<.001) and the Cerebellar functional system (β 0.54, p<.001) of the EDSS. ConclusionThe moderate correlations between the AMSQ and several established physician- and performance based outcome measures underline that the AMSQ, an easily at long-distance administrable PROM, could be considered as a reliable outcome measure for the monitoring of MS in daily practice. Additional research is needed to support these findings.

Effect of Acupuncture on Cytokine Levels in Persons with Multiple Sclerosis: A Randomized Controlled Trial.

Background: Cytokines have been found to play a role in the disease activity of multiple sclerosis (MS). Previous studies indicate that acupuncture can affect cytokine levels in persons with other inflammatory diseases. Objectives: The aim of this study is to investigate the effect of acupuncture on cytokine levels and health-related quality of life (HRQoL) in persons with MS. Materials and Methods: A single-blind, randomized controlled trial was performed. Participants (n = 66) were randomized into three groups (real acupuncture, sham acupuncture, and reference). Participants in the real acupuncture and sham groups received six treatments during a period of 4 weeks. The serum levels of 11 pro- and anti-inflammatory cytokines (IFNγ, IL-1β, IL-6, IL-8, IL-12p70, IL-13, TNFα, IL-10, IL-4, IL-2, and IL-17A) were assessed at baseline, after 2 and 4 weeks of treatment, and 4 weeks after the final treatment. Changes in HRQoL were assessed using the Functional Assessment of Multiple Sclerosis questionnaire. Results: No statistically significant differences in plasma levels between the three groups were seen for either of the cytokines, nor were there any differences between the groups for HRQoL. Conclusions: In this study, the authors could not demonstrate that a 4-week acupuncture treatment had a measurable effect on the plasma levels of seven selected cytokines or on HRQoL among people with MS. The trial was registered with the ISRCTN registry as ISRCTN34352011.

Validity and reliability of Persian version of the Arm Function in Multiple Sclerosis Questionnaire

Introduction This study aimed to determine the validity and reliability of the Persian version of the Arm Function in Multiple Sclerosis Questionnaire which is a self-report questionnaire for persons with multiple sclerosis (MS). Method This methodological study was performed in the following stages: translation, validity, internal consistency, and test–retest reliability of Persian-AMSQ. The Nine-Hole Peg Test (9HPT), Coin Rotation Task (CRT), and Functional Independence Measure (FIM) for construct validity were used. Psychometric testing was done to ascertain the validity and reliability of the questionnaire. Results In this study, 155 people with MS participated. There were no major linguistic or cultural difficulties in the translation of AMSQ. Face and content validity confirmed by experts and people with MS. The internal consistency was high (Cronbach’s α = 0.99). Test–retest reliability, as measured with intra-class coefficient, was 0.98. Correlations with 9HPT (r = 0.54), CRT (r = 0.16), and FIM (r = −0.54) were significant ( p &lt; 0.05). Conclusion The Persian-AMSQ appears to be a valid and reliable questionnaire for measuring upper extremity dysfunction in MS.

Depression, Anxiety, and Stress Relative to Swallowing Impairment in Persons with Multiple Sclerosis

Dysphagia and symptoms of depression, anxiety and stress are common in persons with multiple sclerosis (MS). We posited a relationship between dysphagia and increased frequency of psychological symptoms. Therefore, the aim of the present study was to examine associations between symptoms of psychological difficulties, use of emotional suppression and cognitive reappraisal strategies, and dysphagia status in persons with MS. One hundred persons with MS were prospectively assessed in multiple domains of functioning: cognitive, psychological, and dysphagia-related. Participants underwent cognitive screening with the Mini Mental State Examination and completed two psychological inventories: The depression, anxiety and stress scale (DASS)-21 and the Emotion Regulation Questionnaire. Further, they completed the dysphagia in Multiple Sclerosis questionnaire. A speech-language pathologist evaluated persons suspected of having dysphagia with the Mann Assessment of Swallowing Ability. Dysphagia was present in 29 persons with MS, and the sample was split accordingly. The two groups differed at baseline with respect to Expanded Disability Status Scale scores. There were significant between-group differences for mental health symptoms and for use of emotional regulation strategies. Accordingly, multivariate logistic regressions showed that increased symptoms of psychological stress, decreased use of cognitive reappraisal strategies, and increased indicators of emotional suppression independently predicted the presence of dysphagia. There was a clear pattern towards poorer psychological well-being in persons with dysphagia compared to those without. Psychological difficulties may contribute to the manifestation or worsening of dysphagia and should be addressed in treatment planning and future investigations. Therapeutic interventions that promote improvement in mental state alongside swallowing function may be highly beneficial.

Accuracy of the Brazilian version of the DYMUS questionnaire for the screening of oropharyngeal dysphagia in multiple sclerosis

BackgroundOropharyngeal dysphagia is a common symptom of many neurological diseases, including Multiple Sclerosis (MS). Early identification of the risk of dysphagia in neurological patients is very important for early referral for specialized evaluations of oropharyngeal swallowing and treatments. The Dysphagia in Multiple Sclerosis (DYMUS) questionnaire has been translated and validated in different countries over the last 10 years. We aimed to analyze the accuracy of the Brazilian Portuguese version of the DYMUS (DYMUS-BR) questionnaire in identifying dysphagia in patients with MS. MethodsThe DYMUS questionnaire and a videofluorographic swallowing study (VFSS) were conducted in 30 patients with MS. Dysphagia was identified by at least one abnormal response and was considered alarming when the DYMUS scores were equal to or higher than 3. Patients were considered to have dysphagia in the VFSS when one or more signs of impairment in the efficiency and/or safety of swallowing were detected. ResultsAccording to the initial self-assessment, 37% (N = 11) of patients with MS self-reported with dysphagia. According to the DYMUS-BR scores, 53% (N = 16) of the patients with MS were classified as having dysphagia. The sensitivity, specificity, and positive and negative predictive values of the DYMUS-BR questionnaire for the detection of dysphagia as measured by the VFSS were 50% [95% confidence interval (CI) 29–71], 78% (95% CI 61–90), 60% (95% CI 42–76), and 70% (95% CI 60–78), respectively. The area under the receiver-operating characteristic curve for detecting dysphagia was 64% (95% CI 49–79). ConclusionThe accuracy of the DYMUS-BR questionnaire is poor to detect mild swallowing impairment in patients with MS. However, we suggest longitudinal follow-up in patients with low DYMUS-BR scores for early detection of oropharyngeal dysphagia.

Comorbidity in a sample of Egyptian patients with multiple sclerosis

Background Comorbidities are commonly associated with multiple sclerosis (MS). Not only do they delay the diagnosis of MS but also deteriorate the quality of life, progress the disease, and perhaps increase health care costs. This study was performed to assess the prevalence of comorbidities in Egyptian patients with MS and to evaluate its effect on the cognitive function, disability, and disease relapse. Patients and methods All patients were subjected to clinical assessment and cognitive evaluation using the mini-mental state examination and the symbol digit modalities test. The relapse was assessed using the Assessing Relapse in Multiple Sclerosis questionnaire. Results The current study included 420 participants. Of them, 310 patients had MS, whereas 110 did not have MS (control group). The most common comorbidities among patients with MS were depression, in 71 (22.9%); anxiety, in 68 (21.9%); and hypertension, in 59 (19.0%). Patients with MS with comorbidities experienced a statistically significant (P&lt;0.001) lower mean of mini-mental state examination (26.61±1.88) and symbol digit modalities test (37.44±9.65), in contrast with those without comorbidity. There was no statistically significant difference between both groups regarding comorbidity count (P=0.507) and individual comorbidities (P&gt;0.05). Conclusion Egyptian patients with MS and comorbidities were more vulnerable to develop cognitive dysfunction and disability, relative to those without. However, the negative effect of comorbidities on disease relapse was not established. Employment of such knowledge in MS treatment protocols might reflect considerably on the quality of life and disease outcomes.
