The Health Education for Persons with Multiple Sclerosis (HEMS) program was developed in response to the need for interventions aimed at increasing physical activity for individuals with Multiple Sclerosis (MS). It was developed and evaluated using Drum and colleagues (2009) guidelines for implementing health promotion programs for individuals with disabilities. The purpose of this feasibility study is to describe the development, implementation, and evaluation of the HEMS program. Thirteen individuals with MS completed the 8-week health education program...

Interferon beta (IFNß) is a common treatment used for multiple sclerosis (MS) which acts through the activation of the JAK-STAT pathway. However, this therapy is not always effective and currently there are no reliable biomarkers to predict therapeutic response. We postulate that the heterogeneity in the response to IFNß therapy could be related to differential activation patterns of the JAK-STAT signaling pathway. Our aim was to evaluate the basal levels and the short term activation of this pathway after IFNß stimulation in untreated and IFNß treated patients, as well as according to therapeutic response...

Transforming growth factor-beta (TGF-β) is a pleiotropic cytokine that has been shown to influence the differentiation and function of T cells. The role that TGF-β plays in immune-mediated disease, such as multiple sclerosis (MS), has become a major area of investigation since CD4(+) T cells appear to be a major mediator of autoimmunity. This review provides an analysis of the literature on the role that TGF-β plays in the generation and regulation of encephalitogenic and regulatory T cells in experimental autoimmune encephalomyelitis (EAE), an animal model of MS, as well as in T cells of MS patients...

Highly multiplexed point of care tests could improve diagnostic accuracy and differential diagnostic capacity in for instance emergency medicine and low resource environments. Available technology platforms for POC biomarker detection are typically simplex or low-plexed, whereas common lab-based microarray systems allow for the simultaneous detection of thousands of DNA or protein biomarkers. In this study, we demonstrate a novel suspension particle array platform that utilizes 900 μm bricks for POC amenable colorimetric biomarker detection with an encoding capacity of over two million...

There is a long history of research on acetylcholine (ACh) function in myelinating glia, but a resurgence of interest recently as a result of the therapeutic potential of manipulating ACh signaling to promote remyelination, and the broader interest in neurotransmitter signaling in activity-dependent myelination. Myelinating glia express all the major types of muscarinic and nicotinic ACh receptors at different stages of development, and acetylcholinesterase and butyrylcholinesterase are highly expressed in white matter...

Ribbing disease, or multiple diaphyseal sclerosis, is a rare diaphyseal sclerosis of unknown etiology. Patients with this pathology usually present with asymmetric pain limited to the lower extremities. Though all efforts are made to relieve the progressive pain associated with Ribbing disease, no medical or surgical treatments have been established yet. In this case report, we followed up a Ribbing case with sclerotic bone fenestration for 5 years. The radiological changes and the clinical effects are described, and the different Ribbing treatments are then briefly reviewed...

Hashimoto's thyroiditis (HT) is the most common organ-specific autoimmune disease and is believed to be a predominately T cell-mediated autoimmunity. Signal transducer and activator of transcription (STAT)3 is a crucial transcription factor of T cell-mediated immunity, with key roles in the proliferation and migration of T helper (Th) cells, differentiation of Th cells into Th17 cells, and the balance between Treg cells and Th17 cells. Flavonoid luteolin has been shown to markedly inhibit Tyr705 activation/phosphorylation of STAT3 and exert anti-inflammatory effects in multiple sclerosis...

Fingolimod is an oral sphingosine-1-phosphate (S1P) receptor modulator and the first oral therapy for relapsing-remitting multiple sclerosis. Its use has been complicated by a low rate of cystoid macular edema usually in the first 3 months after commencement of the medication. We report the case of a 34-year-old male with relapsing-remitting multiple sclerosis, who developed acute anterior uveitis on day 5 of fingolimod treatment. He responded to appropriate treatment and cessation of drug, but developed low-grade chronic anterior uveitis without cystoid macular edema...

: MicroRNAs (miRNA) play an important role in post-transcriptional gene regulation of several physiological and pathological processes. In multiple sclerosis (MS), a chronic inflammatory and degenerative disease of the CNS, and in its mouse model, the experimental autoimmune encephalomyelitis (EAE), miRNA dysregulation has been mainly related to immune system dysfunction and white matter (WM) pathology. However, little is known about their role in gray matter pathology. Here, we explored miRNA involvement in the inflammation-driven alterations of synaptic structure and function, collectively known as synaptopathy, a neuropathological process contributing to excitotoxic neurodegeneration in MS/EAE...

The Gram-negative, rod-shaped, anaerobe bacteria Tissierella praeacuta was first described in 1908 by Tissier. However, during the past decade, Clostridium hastiforme has been recognised as a later synonym of T. praeacuta. C. hastiforme/T. praeacuta has only rarely been described in previous literature as a cause of human infection. We present here a case report of C. hastiforme/T. praeacuta bacteraemia secondary to pyometra in a 64-year-old woman with a history of multiple sclerosis and an intrauterine device inserted three decades earlier...

We examined progranulin (PGRN) levels in cerebrospinal fluid (CSF) samples during the acute phase in 15 patients with neuromyelitis optica spectrum disorders (NMOSD) and compared the results with those from 17 patients with multiple sclerosis (MS), 30 patients with other inflammatory neurological diseases (OIND), and 20 non-inflammatory controls (NIC). CSF PGRN levels of NMOSD patients were significantly higher than those of MS patients and NICs. These levels correlated with CSF interleukin-6 levels, CSF cell counts, CSF protein levels, improvements in the Expanded Disability Status Scale score, and affected total spinal cord lesion length in the NMOSD patients...

The d-mannuronic acid (M2000) is a novel nonsteroidal anti-inflammatory drug that has immunosuppressive effects together with antioxidant property. M2000 has shown a notable efficacy in experimental models of multiple sclerosis, rheumatoid arthritis, and nephrotic syndrome. In this work, the effect of M2000 on the treatment of Alzheimer's disease (AD) was performed by Morris water maze experiment, and the immunological assessments were carried out by Western blot, apoptosis (procaspase-3, Bax/Bcl2, P53), enzymatic (superoxide dismutase [SOD]), and nonenzymatic oxidative stress (malondialdehyde [MDA]) tests...

Multiple sclerosis has become an ever-increasing challenge to neurologists. With the release of the latest medications on the market, Brazilian neurologists feel divided between following their patients' evolution in accordance with the strict rules established by the Brazilian Ministry of Health regarding drug distribution, or following disease progression and worsening in accordance with the evidence in the literature. Therefore, a systematic review of the main published treatment guidelines was conducted and an escalating therapy proposed for guiding multiple sclerosis patient treatment in Brazil...

Reactive astrocytes are strongly induced by central nervous system (CNS) injury and disease, but their role is poorly understood. Here we show that a subtype of reactive astrocytes, which we termed A1, is induced by classically activated neuroinflammatory microglia. We show that activated microglia induce A1 astrocytes by secreting Il-1α, TNF and C1q, and that these cytokines together are necessary and sufficient to induce A1 astrocytes. A1 astrocytes lose the ability to promote neuronal survival, outgrowth, synaptogenesis and phagocytosis, and induce the death of neurons and oligodendrocytes...
