Background
Balance impairments are common in people with multiple sclerosis (MS), with reduced ability to maintain position and delayed responses to postural adjustments. Pilates is a popular ...alternative method for balance training that may reduce the rapid worsening of symptoms and the increased risk of secondary conditions (eg, depression) that are frequently associated with physical inactivity.
Objective
In this paper, we aimed to describe the design, development, and usability testing of MS Fitness Intervention Training (MS-FIT), a Kinect-based tool implementing Pilates exercises customized for MS.
Methods
MS-FIT has been developed using a user-centered design approach (design, prototype, user feedback, and analysis) to gain the target user’s perspective. A team composed of 1 physical therapist, 2 game programmers, and 1 game designer developed the first version of MS-FIT that integrated the knowledge and experience of the team with MS literature findings related to Pilates exercises and balance interventions based on exergames. MS-FIT, developed by using the Unity 3D (Unity Technologies) game engine software with Kinect Sensor V2 for Windows, implements exercises for breathing, posture, and balance. Feedback from an Italian panel of experts in MS rehabilitation (neurologists, physiatrists, physical therapists, 1 statistician, and 1 bioengineer) and people with MS was collected to customize the tool for use in MS. The context of MS-FIT is traveling around the world to visit some of the most important cities to learn the aspects of their culture through pictures and stories. At each stay of the travel, the avatar of a Pilates teacher shows the user the exercises to be performed. Overall, 9 people with MS (n=4, 44% women; mean age 42.89, SD 11.97 years; mean disease duration 10.19, SD 9.18 years; Expanded Disability Status Scale score 3.17, SD 0.75) were involved in 3 outpatient user test sessions of 30 minutes; MS-FIT’s usability was assessed through an ad hoc questionnaire (maximum value=5; higher the score, higher the usability) evaluating easiness to use, playability, enjoyment, satisfaction, and acceptance.
Results
A user-centered design approach was used to develop an accessible and challenging tool for balance training. All people with MS (9/9, 100%) completed the user test sessions and answered the ad hoc questionnaire. The average score on each item ranged from 3.78 (SD 0.67) to 4.33 (SD 1.00), which indicated a high usability level. The feedback and suggestions provided by 64% (9/14) of people with MS and 36% (5/14) of therapists involved in the user test were implemented to refine the first prototype to release MS-FIT 2.0.
Conclusions
The participants reported that MS-FIT was a usable tool. It is a promising system for enhancing the motivation and engagement of people with MS in performing exercise with the aim of improving their physical status.
Objective
This study was undertaken to assess the impact of immunosuppressive and immunomodulatory therapies on the severity of coronavirus disease 2019 (COVID‐19) in people with multiple sclerosis ...(PwMS).
Methods
We retrospectively collected data of PwMS with suspected or confirmed COVID‐19. All the patients had complete follow‐up to death or recovery. Severe COVID‐19 was defined by a 3‐level variable: mild disease not requiring hospitalization versus pneumonia or hospitalization versus intensive care unit (ICU) admission or death. We evaluated baseline characteristics and MS therapies associated with severe COVID‐19 by multivariate and propensity score (PS)‐weighted ordinal logistic models. Sensitivity analyses were run to confirm the results.
Results
Of 844 PwMS with suspected (n = 565) or confirmed (n = 279) COVID‐19, 13 (1.54%) died; 11 of them were in a progressive MS phase, and 8 were without any therapy. Thirty‐eight (4.5%) were admitted to an ICU; 99 (11.7%) had radiologically documented pneumonia; 96 (11.4%) were hospitalized.
After adjusting for region, age, sex, progressive MS course, Expanded Disability Status Scale, disease duration, body mass index, comorbidities, and recent methylprednisolone use, therapy with an anti‐CD20 agent (ocrelizumab or rituximab) was significantly associated (odds ratio OR = 2.37, 95% confidence interval CI = 1.18–4.74, p = 0.015) with increased risk of severe COVID‐19. Recent use (<1 month) of methylprednisolone was also associated with a worse outcome (OR = 5.24, 95% CI = 2.20–12.53, p = 0.001). Results were confirmed by the PS‐weighted analysis and by all the sensitivity analyses.
Interpretation
This study showed an acceptable level of safety of therapies with a broad array of mechanisms of action. However, some specific elements of risk emerged. These will need to be considered while the COVID‐19 pandemic persists. ANN NEUROL 2021;89:780–789

Background: Multiple sclerosis (MS) affects the cognitive and motor domains. Muscle weakness often leads to abnormal gait. Several solutions are rising, including the use of passive exoskeletons. ...Objective: The purpose of this study is to evaluate the effect of a first-ever use of a passive exoskeleton on walking ability in people with MS. Methods: We recruited 50 persons with MS. All subjects were assessed using the 2-min walking test, the timed 25-foot walk test, and a two-stage rate of perceived exertion (RPE) without the exoskeleton (T0) and with the exoskeleton (T1). Results: The data showed a significant decrease in walking endurance while the exoskeleton is worn (2-min walking test: T0: 65.19 ± 23.37 m; T1: 59.40 ± 22.99; p < 0.0001) and a not significant difference in walking speed on a shortened distance (T0: 15.71 ± 10.30 s; T1: 15.73 ± 11.86 s; p = 0.25). No significant differences were also found for the effort perception scale (RPE: T0: 13.24 ± 3.01; T1: 13.60 ± 2.9; p = 0.3). Seventy-two percent of subjects reported a positive or neutral global perceived effect. Conclusions: The exoskeleton does not add any fatiguing or negative effects. Although the walking performance decreases, the overall perception of the subjects is positive. Further studies are needed to evaluate the effect of the exoskeleton on gait quality.
Background:
The MuSC-19 project is an Italian cohort study open to international partners that collects data on multiple sclerosis (MS) patients with COVID-19. During the second wave of the pandemic, ...serological tests became routinely available.
Objective:
To evaluate the seroprevalence of anti-SARS-CoV-2 antibodies according to the use of disease-modifying therapy (DMT) in a subset of patients included in the MuSC-19 data set who had undergone a serological test.
Methods:
We evaluated the association between positive serological test results and time elapsed since infection onset, age, sex, Expanded Disability Status Scale score, comorbidities and DMT exposure using a multivariable logistic model.
Results:
Data were collected from 423 patients (345 from Italy, 61 from Turkey and 17 from Brazil) with a serological test performed during follow-up. Overall, 325 out of 423 tested patients (76.8%) had a positive serological test. At multivariate analysis, therapy with anti-CD20 was significantly associated with a reduced probability of developing antibodies after COVID-19 (odds ratio (OR) = 0.20, p = 0.002).
Conclusion:
Patients with MS maintain the capacity to develop humoral immune response against SARS-COV-2, although to a lesser extent when treated with anti-CD20 drugs. Overall, our results are reassuring with respect to the possibility to achieve sufficient immunization with vaccination.

Introduction
Arm and hand function deficits are commonly in people with multiple sclerosis (PwMS). The Arm Function in Multiple Sclerosis Questionnaire (AMSQ) is a novel self-administered instrument ...specifically developed to evaluate upper limb function in MS. The aim of this study was to translate and adapt the AMSQ into Italian and to assess its psychometric properties in PwMS. Validity (structural, construct, and known-groups) and reliability (internal consistency, test-retest, and measurement error) were assessed.
Materials and methods
From June 2017 to February 2018, a prospective cohort of PwMS among those followed as outpatients at the Rehabilitation Services of the Italian Multiple Sclerosis Society (AISM) of Genoa, Padua, and Vicenza was involved in the study. Construct validity of AMSQ was determined by examining correlations with the Italian version of ABILHAND, Modified Fatigue Impact Scale (MFIS), and Functional Independence Measure (FIM).
Results
A total of 234 PwMS were enrolled. The mean AMSQ total score was 67.3 (SD = 38.4). Factor analysis results suggested one factor. As expected, moderate to high correlation coefficients were found between AMSQ and ABILHAND (− 0.79), MFIS (0.50) and its subsets, and FIM (− 0.60) and its subsets involving upper limb functioning. PwMS with higher EDSS reported worse total score of AMSQ than patients with low disability. The internal consistency of the 31 items was high (Cronbach’s
α
, 0.98). Test-retest reliability, as measured with ICC, was 0.96 (95% IC, 0.93–0.98), and measurement error was about 8.3 points showing good reliability.
Discussion
AMSQ has been adapted and validated, it is a reliable questionnaire for Italian PwMS.

Previous studies, dating back to the 1960s disclosed a progressive increase in multiple sclerosis (MS) incidence and prevalence in the Province of Padua. To further analyze whether this trend is the ...effect of the improved diagnostic procedures or is primarily related to a real increase risk of MS, we analyzed MS incidence and prevalence of the 5-year period 2011-2015.
Patients with a diagnosis of MS or clinically isolated syndrome highly suggestive of MS were included in the study. All available sources of clinical and administrative information were evaluated. Mean annual incidence in the 5-year period 2011-2015 and the prevalence on December 31, 2015 were calculated.
The 2011-2015 mean incidence was 6.5/100,000/year, 7.9 for females, 4.1 for males. The overall prevalence was 182/100,000, 241 for females, 116 for males. Compared to the 2000-2009 period, mean age at onset, onset-diagnosis delay and F/M ratio did not significantly change. Since the 1960s, incidence and prevalence of MS linearly increased with no interposed plateau periods.
MS incidence and prevalence further and significantly increased in the period 2011-2015. Our 1965-2015 data indicate a real increased risk of MS and stress a role of exogenous factors in MS susceptibility.
It is unclear how multiple sclerosis (MS) affects the severity of COVID-19. The aim of this study is to compare COVID-19-related outcomes collected in an Italian cohort of patients with MS with the ...outcomes expected in the age- and sex-matched Italian population.
Hospitalization, intensive care unit (ICU) admission, and death after COVID-19 diagnosis of 1,362 patients with MS were compared with the age- and sex-matched Italian population in a retrospective observational case-cohort study with population-based control. The observed vs the expected events were compared in the whole MS cohort and in different subgroups (higher risk: Expanded Disability Status Scale EDSS score > 3 or at least 1 comorbidity, lower risk: EDSS score ≤ 3 and no comorbidities) by the χ
test, and the risk excess was quantified by risk ratios (RRs).
The risk of severe events was about twice the risk in the age- and sex-matched Italian population: RR = 2.12 for hospitalization (
< 0.001), RR = 2.19 for ICU admission (
< 0.001), and RR = 2.43 for death (
< 0.001). The excess of risk was confined to the higher-risk group (n = 553). In lower-risk patients (n = 809), the rate of events was close to that of the Italian age- and sex-matched population (RR = 1.12 for hospitalization, RR = 1.52 for ICU admission, and RR = 1.19 for death). In the lower-risk group, an increased hospitalization risk was detected in patients on anti-CD20 (RR = 3.03,
= 0.005), whereas a decrease was detected in patients on interferon (0 observed vs 4 expected events,
= 0.04).
Overall, the MS cohort had a risk of severe events that is twice the risk than the age- and sex-matched Italian population. This excess of risk is mainly explained by the EDSS score and comorbidities, whereas a residual increase of hospitalization risk was observed in patients on anti-CD20 therapies and a decrease in people on interferon.
Background and purpose
Clinical outcomes of multiple sclerosis (MS) patients affected by coronavirus disease 2019 (COVID‐19) have been thoroughly investigated, but a further analysis on main signs ...and symptoms and their risk factors still needs attention. The objective of this study was to group together and describe based on similarity the most common signs and symptoms of COVID‐19 in MS patients and identify all factors associated with their manifestation.
Method
Logistic and linear regression models were run to recognize factors associated with each pooled group of symptoms and their total number.
Results
From March 2020 to November 2021, data were collected from 1354 MS patients with confirmed infection of COVID‐19. Ageusia and anosmia was less frequent in older people (odds ratio OR 0.98; p = 0.005) and more in smoker patients (OR 1.39; p = 0.049). Smoke was also associated with an incremental number of symptoms (OR 1.24; p = 0.031), substance abuse (drugs or alcohol), conjunctivitis and rash (OR 5.20; p = 0.042) and the presence of at least one comorbidity with shortness of breath, tachycardia or chest pain (OR 1.24; p = 0.008). Some disease‐modifying therapies were associated with greater frequencies of certain COVID‐19 symptoms (association between anti‐CD20 therapies and increment in the number of concomitant symptoms: OR 1.29; p = 0.05). Differences in frequencies between the three waves were found for flu‐like symptoms (G1, p = 0.024), joint or muscle pain (G2, p = 0.013) and ageusia and anosmia (G5, p < 0.001). All cases should be referred to variants up to Delta.
Conclusion
Several factors along with the choice of specific therapeutic approaches might have a different impact on the occurrence of some COVID‐19 symptoms.

Background and purpose
Some studies have shown that air pollution, often assessed by thin particulate matter with diameter below 2.5 µg/m3 (PM2.5), may contribute to severe COVID‐19 courses, as well ...as play a role in the onset and evolution of multiple sclerosis (MS). However, the impact of air pollution on COVID‐19 has never been explored specifically amongst patients with MS (PwMS). This retrospective observational study aims to explore associations between PM2.5 and COVID‐19 severity amongst PwMS.
Methods
Data were retrieved from an Italian web‐based platform (MuSC‐19) which includes PwMS with COVID‐19. PM2.5 2016–2018 average concentrations were provided by the Copernicus Atmospheric Monitoring Service. Italian patients inserted in the platform from 15 January 2020 to 9 April 2021 with a COVID‐19 positive test were included. Ordered logistic regression models were used to study associations between PM2.5 and COVID‐19 severity.
Results
In all, 1087 patients, of whom 13% required hospitalization and 2% were admitted to an intensive care unit or died, were included. Based on the multivariate analysis, higher concentrations of PM2.5 increased the risk of worse COVID‐19 course (odds ratio 1.90; p = 0.009).
Conclusions
Even if several other factors explain the unfavourable course of COVID‐19 in PwMS, the role of air pollutants must be considered and further investigated.
