BACKGROUND: Although cognitive fatigue plays a significant part in Multiple Sclerosis (MS) related impairment, knowledge regarding it is largely lacking. Until now, not many tools are available to a clinician to detect cognitive fatigue. The subjective tools of fatigue have never been reliable.tabl OBJECTIVES: To assess the prevalence and clinical/ demographic profile of cognitive fatigue in MS using novel clinical and electrophysiological measures and to find their accuracy. We also aimed to test the three leading hypotheses - the temporal fatigue, cognitive load and cognitive domain hypotheses of cognitive fatigue in MS...

Intrathecal B-lymphocyte activation is a hallmark of multiple sclerosis (MS), a multi-factorial inflammatory-demyelinating disease of the central nervous system. Such activation has a counterpart in the cerebrospinal fluid (CSF) oligoclonal IgG bands (OCB), whose diagnostic role in MS has been downgraded within the current McDonald's criteria. With a theoretico-practical approach, the authors review the physiopathological basis of the CSF dynamics, and the state-of-the-art of routine CSF analysis and CSF biomarkers in MS...

Cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) is an inherited small vessel disease, manifesting as recurrent ischaemic events, migraine with aura, behavioural disturbance and cognitive decline. We report two patients with CADASIL masquerading as multiple sclerosis (MS). A 23year old female presented with a visual scotoma and was discovered to have a corresponding retinal cotton wool spot. MRI brain revealed diffuse T2 hyperintensities suggestive of demyelination...

In this study, we strove to substantiate the ability of linc-MAF-4 to act as a regulator of pathogenesis during multiple sclerosis (MS). We recruited 34 patients who were diagnosed with MS according to the revised McDonald Criteria. Six patients with MS and 5 healthy volunteers contributed peripheral blood mononuclear cells for microarray analysis. Subsequent knockdown and overexpression of linc-MAF-4 in naive CD4(+) T cells from the additional 28 patients with MS was performed to track changes in CD4(+) T-cell subsets and their function as well as to confirm results from the prior microarray analysis...

The evolution of data exchange in Mass Spectrometry spans decades and has ranged from human-readable text files representing individual scans or collections thereof (McDonald et al., 2004) through the official standard XML-based (Harold, Means, & Udemadu, 2005) data interchange standard (Deutsch, 2012), to increasingly compressed (Teleman et al., 2014) variants of this standard sometimes requiring purely binary adjunct files (Römpp et al., 2011). While the desire to maintain even partial human readability is understandable, the inherent mismatch between XML's textual and irregular format relative to the numeric and highly regular nature of actual spectral data, along with the explosive growth in dataset scales and the resulting need for efficient (binary and indexed) access has led to a phenomenon referred to as "technical drift" (Davis, 2013)...

The majority of patients presenting with a first clinical symptom suggestive of multiple sclerosis (MS) do not fulfill the MRI criteria for dissemination in space and time according to the 2010 revision of the McDonald diagnostic criteria for MS and are thus classified as clinically isolated syndrome (CIS). To re-evaluate the utility of cerebrospinal fluid (CSF) analysis in the context of the revised McDonald criteria from 2010, we conducted a retrospective multicenter study aimed at determining the prevalence and predictive value of oligoclonal IgG bands (OCBs) in patients with CIS...

BACKGROUND: The klotho (Klt)-fibroblast growth factor-23 (FGF-23)-vitamin D axis is the main component of calcium (Ca) and phosphorus (P) metabolisms; on the contrary, it is also secreted from the choroid plexus (CP). PURPOSE: This study is aimed at evaluating serum soluble Klt (sKlt), FGF-23, and 25-(OH)-vitamin D levels in multiple sclerosis (MS) patients. METHODS: Thirty-two relapsing-remitting MS patients (11 males and 21 females; mean age 38...

A Bose-Einstein condensate is used as an atomic source for a high precision sensor. A 5×10^{6}  atom F=1 spinor condensate of ^{87}Rb is released into free fall for up to 750 ms and probed with a T=130  ms Mach-Zehnder atom interferometer based on Bragg transitions. The Bragg interferometer simultaneously addresses the three magnetic states |m_{f}=1,0,-1⟩, facilitating a simultaneous measurement of the acceleration due to gravity with a 1000 run precision of Δg/g=1.45×10^{-9} and the magnetic field gradient to a precision of 120  pT/m...

In patients who present with a clinically isolated syndrome (CIS), whose features are suggestive of multiple sclerosis (MS), fulfilling McDonald 2010 magnetic resonance imaging (MRI) criteria for dissemination in space (DIS) and dissemination in time (DIT) enables a diagnosis of MS. While ⩾1 periventricular lesion is included in the 2010 DIS criteria, earlier McDonald criteria required ⩾3 periventricular lesions to confirm DIS and recent Magnetic Resonance Imaging in Multiple Sclerosis (MAGNIMS)-recommended DIS criteria also require ⩾3 lesions...

In light of the published 2012 International Pediatric Multiple Sclerosis Group definitions for pediatric multiple sclerosis (MS) and related disorders and given that pediatric-onset MS is now formally included in the 2010 McDonald criteria for MS, we sought to review these criteria and summarize their application in children with acquired CNS demyelination. In addition, proposals are made for definitions of no evidence of disease activity and inadequate treatment response that are important because of new therapeutic options and trials...

Approximately one-third of children with an acquired demyelinating syndrome (ADS) will be diagnosed with multiple sclerosis (MS), either at onset according to the 2010 McDonald criteria, or on the basis of clinical or MRI evidence of relapsing disease, in the majority of patients within 2-4 years. ADS in adolescents, female patients, and patients with polyfocal deficits is associated with the highest likelihood of MS, while children with acute disseminated encephalomyelitis, those with documented preceding infection, and ADS presentation in young children more commonly portends a monophasic outcome...

OBJECTIVE: To study the contribution of the symptomatic lesion in establishing multiple sclerosis (MS) diagnosis and prognosis. METHODS: We performed an observational study based on a prospective clinically isolated syndrome (CIS) cohort of 1,107 patients recruited for clinical and brain MRI follow-up from 1995 to 2014. Eligible patients (n = 954) were divided into 4 groups according to baseline MRI: patients with a normal MRI (n = 290); patients with a single asymptomatic lesion (n = 18); patients with a single cord/brainstem symptomatic lesion (n = 35); and patients with more than 1 lesion (n = 611)...

BACKGROUND: Radiologically isolated syndrome (RIS) is a sub clinical demyelinating neurological disorder and to date no biomarker that triggers the seminal event has been identified. As for multiple sclerosis (MS), disease activity and clinical course are unpredictable. In MS, exploratory studies reported increased IL-17 levels in CSF but results in detecting IL-17 in serum at different stage of the disease are controversial. OBJECTIVES: We investigate levels of IL-17 in serum and CSF in patients diagnosed at different stages of demyelinating diseases (RIS, CIS, relapsing remitting (RR) or active multiple sclerosis patients:AMS) as a marker of inflammatory condition...

PURPOSE: To quantify protein changes in the morphologically distinct remodeling zone (RZ) and adjacent regions of the human lens outer cortex using spatially directed quantitative proteomics. METHODS: Lightly fixed human lens sections were deparaffinized and membranes labeled with fluorescent wheat germ agglutinin (WGA-TRITC). Morphology directed laser capture microdissection (LCM) was used to isolate tissue from four distinct regions of human lens outer cortex: differentiating zone (DF), RZ, transition zone (TZ), and inner cortex (IC)...

OBJECTIVE: To determine the prognostic value of selected biomarkers in clinically isolated syndromes (CIS) for conversion to multiple sclerosis (MS) and disability accrual. METHODS: Data were acquired from 2 CIS cohorts. The screening phase evaluated patients developing clinically definite MS (CIS-CDMS) and patients who remained as CIS during a 2-year minimum follow-up (CIS-CIS). We determined levels of neurofascin, semaphorin 3A, fetuin A, glial fibrillary acidic protein, and neurofilament light (NfL) and heavy chains in CSF (estimated mean [95% confidence interval; CI])...

BACKGROUND: Comprehensive epidemiologic data for multiple sclerosis (MS) in Poland are limited. The aim of this cross-sectional population-based study was to determine the incidence and prevalence of MS in the Swietokrzyskie Region (central Poland). METHODS: This study identified MS cases every year between 1 January 2010 and 31 December 2014. The study area population on the prevalence day (December 31, 2014) was 1,263,176 (646,506 women and 616,670 men). A total of 1462 patients with a clinically definite diagnosis of MS according to McDonald's criteria (2005), recorded in the Polish Multiple Sclerosis Registry, were considered for estimation of crude, age- and sex-specific prevalence, and incidence...

Platelet activation is increasingly postulated as a possible component of the pathogenesis of multiple sclerosis (MS), especially due to the increased risk of cardiovascular events in MS. Arachidonic acid cascade metabolized by cyclooxygenase (COX) is a key pathway of platelet activation. The aim of our study was to investigate the COX-dependent arachidonic acid metabolic pathway in blood platelets from secondary progressive multiple sclerosis (SP MS) patients. The blood samples were obtained from 50 patients (man n = 22; female n = 28), suffering from SP MS, diagnosed according to the revised McDonald criteria...

BACKGROUND: Various molecules of the coagulation cascade are thought to have varying roles in the pathophysiology of multiple sclerosis (MS). We aimed to find new information about the effects of the coagulation cascade molecules to develop new therapeutic strategies for MS. MATERIALS AND METHODS: Patients with MS were chosen from among patients who were followed up at our hospital. We examined the thrombomodulin (TM) and activated protein C (APC) serum levels in patients with MS and the healthy controls...

OBJECTIVES: To investigate whether inclusion of lesions in the symptomatic region influences the performance of dissemination in space (DIS) criteria for a diagnosis of clinically definite multiple sclerosis (CDMS) in patients with a clinically isolated syndrome (CIS). METHODS: We studied 30 patients with CIS with brainstem/cerebellar and spinal cord syndromes who had MRI scans at the time of CIS and were followed up for the development of CDMS. We retrospectively applied the McDonald 2010 DIS criteria (excluding all lesions in the symptomatic region) to baseline MRI scans and 2 modified DIS criteria: (1) the inclusion of asymptomatic lesions in the symptomatic region in DIS, and (2) the inclusion of any lesion in the symptomatic region in DIS...
