    Abstract Background: Current guidelines state that clopidogrel and other adenosine-diphosphate receptor antagonists (ADPra) should be stopped for at least 7 days before lumbar puncture (LP). This practice may delay the diagnosis of treatable neurological emergencies and may increase the risk of cardiovascular morbidity due to withholding antiplatelets. We aimed to summarize all cases under our care, in which LP was performed without discontinued ADPra.
    Methods: A retrospective case series study of all patients who underwent LP without interruption of ADPRa or with treatment interruption that was shorter than 7 days. Medical records were searched for documented complications. Traumatic tap was defined as cerebrospinal fluid red cell count ≥ 1000 cell/μL. Incidence of traumatic tap among people who underwent LP under ADPRa was compared to traumatic tap incidence in two control groups: LP under aspirin and LP without any anti-platelet.
    Results: 159 patients underwent LP under ADPRa [Age: 68.4 ± 12.1, Female: 63 (40%), 81 (51%) were treated with both aspirin and ADPRa]. 116 procedures were carried out without any interruption of ADPRa. In the other 43, the median delay between treatment interruption and the procedure was 2 days (range: 1-6 days). Incidence of traumatic tap was 8/159 (5%), 9/159 (5.7%) and 4/160 (2.5%) among those who underwent LP under ADPRa, under aspirin and without any anti-platelet, respectively. [X
    Conclusions: Lumbar puncture without discontinuation of ADP receptor antagonists seems safe. Similar case series may ultimately lead to guidelines change.

    Abstract Background: Disease-modifying therapies (DMTs) for people with multiple sclerosis (pwMS) may decrease vaccine effectiveness. We aimed to explore the association between various DMTs and the risk for breakthrough COVID-19.
    Methods: Population-based data from Clalit Health Services, Israel's largest healthcare organization, were used. PwMS treated with DMTs without prior COVID-19 were followed from the commencement of the mass vaccination campaign in December 2020. The end of follow-up was at the time of COVID-19 infection, the receipt of a third vaccine dose or until the end of August 2021. Time-dependent multivariate Cox proportional hazard models were used to estimate hazard ratios for COVID-19 according to vaccination, DMT, age, gender, disability and comorbidities.
    Results: 2511 PwMS treated with DMTs were included (Age: 46.2 ± 14.6, 70% Female, EDSS: 3.0 ± 2.1). Of whom, 2123 (84.5%) received 2 vaccine doses. On multivariate models that included all pwMS, vaccination was protective (HR = 0.41, P < 0.001). On multivariate models that included only fully vaccinated pwMS cladribine, ocrelizumab, S1P receptor modulators and natalizumab were associated with breakthrough COVID-19 (HR = 6.1, 4.7, 3.7 and 3.3; P = 0.004, 0.008, 0.02 and 0.05, respectively). On multivariate models that included unvaccinated and fully vaccinated pwMS on each DMT separately, a protective trend was noted for vaccination on all DMTs (0.09 < HR < 0.65), except for cladribine (HR = 1.1). This protective trend was not statistically significant on ocrelizumab, S1P receptor modulators and natalizumab. COVID-19 among pwMS was generally mild. Only 2 vaccinated pwMS had a severe infection with eventual recovery.
    Conclusions: Vaccination effectively protects pwMS from COVID-19. An increased risk of breakthrough infection was noted on high-efficacy DMTs, however COVID-19 after vaccination was usually mild.

    Abstract The advent of molecular genetic technologies paved a path for the diagnosis of many neurological disorders. Joint evaluation by a neurologist and a medical genetics specialist can potentially increase diagnostic effectiveness by ensuring the exclusion of non-genetic conditions with similar phenotypes and by rationally selecting appropriate genetic diagnostic tools. Therefore, a monthly adult neurogenetics clinic was established. A retrospective review of medical records of all patients who attended the clinic from April 2015 to March 2019 was conducted. Eighty-two patients were evaluated (age: 47.1 ± 15.7, male: 37(45%), 42 (51%) had a positive family history). Disease duration was typically long (11.4 ± 0.9 years). Futile use of diagnostic modalities was very common (45 (55%) had repeated MRI, 28 (34%) hospitalized for observation in neurologic departments, 12 (14%) had a normal metabolic workup, 4 (5%) with a non-conclusive muscle biopsy, 1 with a normal cerebral angiography). Following clinical evaluation, molecular genetic testing was offered to 67 (82%) patients. In the other 15 (18%), routine workup for the exclusion of non-genetic conditions was not complete; obtainable information regarding family members was missing or that a neurogenetic disorder seemed improbable. Twenty-seven (33%) patients received a definitive diagnosis, either a genetic (23, 28%) or non-genetic (4, 5%). Excluding 4 cases of pre-symptomatic diagnosis, the diagnostic yield was 30%. The adherence to genetic testing recommendations was 62%. The reasons for non-adherence were lack of public funding for the required test (52%) and patient decision not to proceed (48%). Given the frequent futile use of diagnostic modalities, referral of non-genetic conditions with similar phenotypes among neurogenetic disorders, and the complexity of clinical genomic data analysis, a multi-disciplinary neurogenetics clinic seems justified.

    Abstract Background: The applicability of mobile digital technology to promote clinical care of people with multiple sclerosis (pwMS) is gaining increased interest as part of the implementation of patient-centered approaches. We aimed at assessing adherence to a smartphone-based e-diary, which was designed to collect patient-reported outcomes (PROs). Secondary objectives were to evaluate the construct and predictive validity of e-diary derived PROs and to explore the various factors that were associated with changes in PROs over time.
    Materials and methods: In this observational cohort study patients downloaded an MS tailored e-diary into their personal smartphones. Report of PROs was enquired once monthly for a period of one year through a smartphone-based application, using previously validated tools. An e-diary derived bodily function summary score (eBF) was defined as the sum of scores depicting vision, limbs function, pain, bowl/ bladder dysfunction, pseudobulbar affect and spasticity. Multiple linear regression and analysis of covariance were used to determine the association between PROs, clinician-reported outcomes (ClinROs) of disease activity and quality of life (QoL). Regression coefficient analysis was used to compare the slope of change in eBF before and after a relapse.
    Results: 97 pwMS downloaded the e-diary [Female: 64 (66%), EDSS 3.4±2.1]. 76 patients (78%) completed the 12-month study period. 53 patients (55%) submitted ≥75% of requested surveys. Anxiety was negatively associated with adherence to periodic PROs assessments by the e-diary. E-diary derived PROs were significantly correlated with corresponding functional system scores (0.38< r <0.8, P<0.001). eBF score significantly predicted QoL (β = -0.36, P = 0.001) while EDSS did not. Change in eBF score over time was independently associated with the occurrence of an MS relapse (F = 4.4, P = 0.04), anxiety (F = 6.4, P = 0.01) and depression (F = 5.1, P = 0.03). Individual regression slopes of eBF scores were significantly higher pre-relapse than post-relapse (3.0±3.3 vs. -0.8±2.0, P = 0.007).
    Conclusion: Adherence of pwMS to recording in an e-diary collecting PROs was high. Changes in e-diary derived PROs over time predict clinical MS relapses on the group level and thus carry the potential of usage in clinical research as well as for improved MS care in real world setting.

    Abstract Background: Poor sleep quality and sleep disorders are more prevalent in individuals with multiple sclerosis (MS) than in the general population. Poor sleep has been correlated with worse MS outcomes. Sleep efficiency (SE) is one of the most sensitive markers of sleep quality. There is very little written about SE and other polysomnography (PSG) parameters and MS measures.
    Methods: This is a retrospective review of 280 consecutive individuals with MS evaluated by PSGs and other standardized MS measures over 13 years at a comprehensive MS center. In addition, the cohort was assessed with 2 fatigue scales, the Epworth Sleepiness Scale, and the Expanded Disability Status Scale. A comparison of means test (independent
    Results: The PSG measures of SE and Total Sleep Time were significantly different between a group of individuals with MS with a disease duration of more than 5 years vs a group of individuals with MS with a disease duration less than or equal to 5 years. Prevalence of obstructive sleep apnea was 63%, higher than reported in the literature while the prevalence of moderate to severe obstructive sleep apnea was 33.4%, which was lower than reported.
    Conclusions: Longer disease duration and worse disability correlate with sleep quality as measured by SE.

    Abstract Background: Adherence to multiple sclerosis (MS) disease-modifying drugs (DMDs) is essential for realization of their optimal effectiveness and benefits.
    Objective: To evaluate the usefulness and validity of a smartphone-based e-diary as a tool for adherence assessment as well as its effectiveness as a promoter of adherence to DMDs.
    Methods: An MS tailored e-diary (MyMS&Me) reminded patients to take their DMDs on time. DMD intake was self-recorded in the e-diary by the participants. Three methods of adherence evaluation were compared: e-diary derived, retrospective self-reported, and the medication possession rate (MPR). The proportion of patients with poor adherence to DMDs (defined as MPR <80%) among e-diary users was compared with a control group without intervention.
    Results: Sixty-two patients downloaded the e-diary (Female: 41 (66%), Expanded Disability Status Scale 3.2 ± 2.2) and 55 controls were enrolled. The median difference between e-diary-derived adherence and the MPR was -3% (95% limits of agreement: -53% to 12%). The median difference between retrospective self-reported adherence and the MPR was 0.3% (95% limits of agreement: -20% to 42%). The proportion of participants with poor adherence to DMDs was similar in the e-diary and control groups (10% vs. 13%,
    Conclusions: Substantial and clinically important disagreement between methods of medication adherence evaluation was noted. Smartphone reminders did not significantly improve the MPR of DMDs.

    Abstract The pathogenesis of most chronic diseases is complex and probably involves the interaction of multiple genetic and environmental risk factors. One way to learn about disease triggers is from statistically significant associations in epidemiological studies. However, associations do not necessarily prove causation. Associations can commonly result from bias, confounding and reverse causation. Several paradigms for causality inference have been developed. Henle-Koch postulates are mainly applied for infectious diseases. Austin Bradford Hill's criteria may serve as a practical tool to weigh the evidence regarding the probability that a single new risk factor for a given disease is indeed causal. These criteria are irrelevant for estimating the causal relationship between exposure to a risk factor and disease whenever biological causality has been previously established. Thus, it is highly probable that past exposure of an individual to definite carcinogens is related to his cancer, even without proving an association between this exposure and cancer in his group. For multifactorial diseases, Rothman's model of interacting sets of component causes can be applied.

    Abstract Purpose of review: In recent years we notice paradigm shifts in the understanding of multiple sclerosis (MS), leading to important transition in the patients' management. This review discusses some of the recent findings and developments underlying the conceptual changes being translated from 'treating the disease' to 'treating the patient' with MS (PwMS).
    Recent findings: Applying advanced technologies combined with cross-disciplinary efforts in the fields of neuropathology, neuroimmunology, neurobiology, and neuroimaging, together with clinical neurology provided support for the notion that MS is not a single disease but rather a spectrum. Predictive markers of disease subtypes, disease activity and response to therapy are being developed; some already applied to practice, allowing informed management. In parallel, population-specific issues, some genetic-driven, others caused by environmental (sun-exposure, life-style, etc.), gender-related (hormones) and epigenetic factors, are being elucidated. Additionally, patient empowerment-based approaches, including integration of patient-reported outcome measures (PRO) as well as tools to enhance patients' adherence to medications, are being developed, some already provided as part of emerging mobile-health technologies.
    Summary: Developments in the MS field, elucidating disease subtypes and interpopulation diversities, together with integration of patient-centered approaches, allow transition toward precision medicine in MS clinical trials and patient care.

    Abstract Background: Spectral Optical Coherence Tomography (OCT) and Visual Evoked Potentials (VEPs) have both emerged as potentially useful biomarkers of cognitive decline in people with multiple sclerosis (PwMS). Their combined use may provide additional predictive value for identifying disease impact, progression, and remyelination capacity above-and-beyond what is captured using either approach alone.
    Objective: We examined the relationship between OCT/VEP measures and cognitive functioning in 205 PwMS. OCT measures included Retinal Nerve Fiber Layer Volume (RNFLV), Papillo-Macular Bundle Volume (PBMV), and Macular Volume (MV). VEP measures included latency of the P100, and inter-ocular latency. Cognitive performance was evaluated across seven separate domains of performance, and for overall cognition, using the NeuroTrax computerized testing battery.
    Results: Both OCT and VEP measures were significantly correlated with cognitive performance across several domains. Linear regression models that controlled for the influence of visual acuity revealed (1) that reduced MV was significantly predictive of poorer visual-spatial functioning, and (2) that delayed VEP latency was significantly predictive of performance in global cognitive functioning and visual-spatial functioning, after controlling for multiple comparisons. Among PwMS with normal visual acuity, PwMS with a combination of both relatively low MV and delayed VEP latency tended to have poorer performance in the domains of global, executive, and visual-spatial functioning compared to PwMS with both high MV and normal VEP latency.
    Conclusion: Approaches that combine the use of OCT and VEP measures can enhance insight into underlying factors that contribute to variance in cognitive functioning in PwMS.
