Multiple Sclerosis (MS) is a heterogeneous disorder of the central nervous system (CNS) that begins as an inflammatory autoimmune disorder mediated by auto-reactive lymphocyte followed by microglial activation and chronic degeneration. The etiology of Multiple Sclerosis (MS) is unknown but several data support the hypothesis of possible infectious agents which may act as a trigger for the pathogenic cascade. Human endogenous retrovirus (HERV-W/MSRV), Epstein Barr Virus (EBV) and Mycobacterium avium ss. paratuberculosis (MAP) have been associated to Multiple Sclerosis. In this study, we evaluated the humoral response against different peptides: the human endogenous retrovirus HERV-Wenv73-88, MAP106c121-132 from MAP, EBNA1 400-413 from EBV and the homologous human peptide MBP85-98 in a cohort of MS patients treated with natalizumab. Results showed a statistically significant difference in the response against the HERV-W peptide in MS patients after two years of natalizumab treatment.

Objective: To explore whether the inflammatory activity is higher in white matter (WM) tracts disrupted by paramagnetic rim lesions (PRLs) and if inflammation in PRL-disrupted WM tracts is associated with disability in people with multiple sclerosis (MS).
Methods: Forty-four MS patients and 16 healthy controls were included. 18 kDa-translocator protein positron emission tomography (TSPO-PET) with the C-PK11195 radioligand was used to measure the neuroinflammatory activity.

To demonstrate the prevalence of malnutrition risk in a specific rehabilitation setting. The secondary aim of the study was to compare Malnutrition Screening Tool (MST) and Malnutrition Universal Screening Tool (MUST) with Nutritional Risk Screening-2002 (NRS-2002). Patients diagnosed with stroke, anoxic brain injury, spinal cord injury, multiple sclerosis, arthritis, neuromuscular diseases, Parkinson's disease, and lymphedema who were admitted to a rehabilitation hospital were included.

The corpus callosum can reveal a "butterfly" pattern on imaging in various conditions, including glioblastoma, primary central nervous system lymphoma, tumefactive multiple sclerosis, and toxoplasmosis. Early differentiation among these conditions is crucial to avoid aggressive treatments. In one case, a 70-year-old woman with a history of multiple sclerosis experienced a neurological decline.

While numerous reviews have assessed the association between traumatic brain injury (TBI) and various mental and physical health outcomes, a comprehensive evaluation of the scope, validity, and quality of evidence is lacking. Here we present an umbrella review of a wide range of health outcomes following TBI and outline outcome risks across subpopulations. On 17 May 2023, we searched Embase, Medline, Global Health, PsycINFO, and Cochrane Database of Systematic Reviews for systematic reviews and meta-analyses.
