OBJECTIVE We set out to assess the dynamics of retinal injury after acute optic neuritis (ON) and their association with clinical visual outcomes. METHODS Thirty-one consecutive patients with acute ON were prospectively analyzed over a 6-month follow-up period. Each month, we used optical coherence tomography (OCT) to assess the thickness of peripapillary(More)
Multiple Sclerosis (MS) is an immune-mediated disease of the Central Nervous System with two major underlying etiopathogenic processes: inflammation and neurodegeneration. The latter determines the prognosis of this disease. MS is the main cause of non-traumatic disability in middle-aged populations. The MS-VisualPath Cohort was set up to study the(More)
BACKGROUND Most patients with multiple sclerosis without previous optic neuritis have thinner retinal layers than healthy controls. We assessed the role of peripapillary retinal nerve fibre layer (pRNFL) thickness and macular volume in eyes with no history of optic neuritis as a biomarker of disability worsening in a cohort of patients with multiple(More)
BACKGROUND In order to retrieve useful information from scientific literature and electronic medical records (EMR) we developed an ontology specific for Multiple Sclerosis (MS). METHODS The MS Ontology was created using scientific literature and expert review under the Protégé OWL environment. We developed a dictionary with semantic synonyms and(More)
OBJECTIVE To identify differences in the metabolomic profile in the serum of patients with multiple sclerosis (MS) compared to controls and to identify biomarkers of disease severity. METHODS We studied 2 cohorts of patients with MS: a retrospective longitudinal cohort of 238 patients and 74 controls and a prospective cohort of 61 patients and 41 controls(More)
OBJECTIVE To assess the decision-making impairment in patients with multiple sclerosis (MS) and how they relate to other cognitive domains. METHODS We performed a cross-sectional analysis in 84 patients with MS, and 21 matched healthy controls using four tasks taken from behavioral economics: (1) risk preferences, (2) choice consistency, (3) delay of(More)
The novelty of this paper is mainly the integration of multi-disciplinary software tools into a control software design environment, namely the Integrated Design Notation (IDN). The IDN supports the design, development and implementation of decentralised distributed control systems. This new environment is based on the UML meta-model standard. The(More)
BACKGROUND Visual recovery after optic neuritis (ON) used to be defined as good, although patients frequently complain of poor vision. METHODS We carried out a prospective study on 38 consecutive patients with acute ON followed monthly for 6 months and evaluated high- and low-contrast visual acuity (HCVA and LCVA, respectively), quality of vision(More)
Monitoring disease burden is an unmeet need in multiple sclerosis (MS). Identifying patients at high risk of disability progression will be useful for improving clinical-therapeutic decisions in clinical routine. To evaluate the role of visual field testing in non-optic neuritis eyes (non-ON eyes) as a biomarker of disability progression in MS. In 109(More)
OBJECTIVE To analyze the characteristics of semantic networks derived from fluency tests in patients with multiple sclerosis (MS). METHODS We built semantic networks by applying co-occurrence statistics to the data from verbal fluency tests performed on patients with MS (n=36) and matched controls (n=200), assessing the differences in network topology.
