The Role of Perceived Energy and Self-Beliefs for Physical Activity and Sports Activity of Patients With Multiple Sclerosis and Chronic Stroke

2021

Physical activity counteracts some of the negative consequences associated with chronic neurological diseases. Here, we describe the levels of physical activity (PA) and sports activity (Sport) in patients with multiple sclerosis (pMS, n = 59) and chronic stroke (pStroke, n = 67) and test compliance with the recommendation for health-promoting physical activity of the World-Health Organization (WHO). Secondly, we tested for differences between the groups of patients, and thirdly, we examined relationships between PA and Sport with psychological indicators of perceived energy (fatigue and vitality) and self-beliefs (self-efficacy and self-control). Psychological constructs were assessed with…

Galectin-3 and Lp(a) plasma concentrations and advanced carotid atherosclerotic plaques: Correlation with plaque presence and features

2019

Introduction: atherosclerosis is one of the leading causes of death and morbidity worldwide. It consists in the development of plaques in the intima media layers of arteries due to lipid accumulation and oxidation, causing massive inflammation. We aim to better understand the role of Galectin-3 (Gal-3) and Lipoprotein(a) [Lp(a)] as possible peripheral markers of plaque presence. Methods: Gal-3 and Lp(a) were measured in plasma samples from 99 patients undergoing carotid endarterectomy and 78 healthy controls, by immunometric assays. Plaques were classified histologically, according to the American Heart Association (AHA) guidelines as type Va (fibroatheroma), Vb (mainly calcific) and Vl (co…

Differences in intercellular communication during clinical relapse and gadolinium-enhanced MRI in patients with relapsing remitting multiple sclerosi…

2018

This study was designed based on the hypothesis that changes in both the levels and surface marker expression of extracellular vesicles (EVs) isolated from the cerebrospinal fluid (CSF) may be associated with the clinical form, disease activity, and severity of multiple sclerosis (MS). The analyzes were performed on subjects affected by MS or other neurological disorders. EVs, which were isolated by ultracentrifugation of CSF samples, were characterized by flow cytometry. A panel of fluorescent antibodies was used to identify the EV origin: CD4, CCR3, CCR5, CD19, and CD200, as well as isolectin IB4. The Mann–Whitney U-test and Kruskal–Wallis test were used for statistical analyzes. EVs isol…

Magnetic Resonance Venography of chronic cerebrospinal venous insufficiency in patients with associated multiple sclerosis

2011

Background: Multiple sclerosis (MS) is a chronic disease with not well understood etiology. Recently, a possible association of MS with compromised venous outflow from the brain and spinal cord has been studied (chronic cerebrospinal venous insufficiency – CCSVI). Angioplasties of internal jugular veins (IJV) and azygous vein (AV) have given promising results, with improvements in patients’ clinical status. Material/Methods: 830 patients with clinically defined MS were scanned from the level of sigmoid sinuses to the junction with brachiocephalic veins, as well as at the level of AV. T2-weighted, 2D TOF and FIESTA sequences were used. Results: The examination revealed a slower blood flow in…

Motor imagery in unipolar major depression

2014

International audience; Background: Motor imagery is a potential tool to investigate action representation, as it can provide insights into the processes of action planning and preparation. Recent studies suggest that depressed patients present specific impairment in mental rotation. The present study was designed to investigate the influence of unipolar depression on motor imagery ability. Methods: Fourteen right-handed patients meeting DSM-IV criteria for unipolar depression were compared to 14 matched healthy controls. Imagery ability was accessed by the timing correspondence between executed and imagined movements during a pointing task, involving strong spatiotemporal constraints (spee…

Data from: Is the association between health-related quality of life and fatigue mediated by depression in patients with multiple sclerosis? A Spanis…

2017

Objectives: To determine the mediating effects of depression on health-related quality of life and fatigue in individuals with multiple sclerosis (MS). Design: A cross-sectional study. Setting: Tertiary urban hospital. Participants: One hundred and eight patients (54% women) with MS participated in this study. Outcome measures: Demographic and clinical data (weight, height, medication, and neurological impairment), fatigue (Fatigue Impact Scale-FIS), depression (Beck Depression Inventory-BDI/II) and health-related quality of life (Short-Form Health Survey 36 - SF36) were collected. Results: Fatigue was significantly associated with bodily pain, physical function, mental health and depressio…

Analysis of complement C3 activation products in human atherosclerotic lesions.

1991

Abstract Cleavage of the complement C3 protein is essential for complement activation. Saline extracts of human atherosclerotic lesions were examined by various techniques for the presence of C3 cleavage fragments. Crossed intermediate gel immunoelectrophoresis revealed that native C3 was the predominate C3 protein in extracts and that the C3dg fragment was also detected. SDS-PAGE/ Western blot analyses of lesion extracts employing monoclonal antibodies directed at C3c and C3dg fragment determinants demonstrated molecular weight bands corresponding to the known molecular weights of all the physiologic C3 cleavage fragments, except Cab which is known to have a short half-life. After C3, the …

Linking immune-mediated damage to neurodegeneration in multiple sclerosis: could network-based MRI help?

2021

Abstract Inflammatory demyelination characterizes the initial stages of multiple sclerosis, while progressive axonal and neuronal loss are coexisting and significantly contribute to the long-term physical and cognitive impairment. There is an unmet need for a conceptual shift from a dualistic view of multiple sclerosis pathology, involving either inflammatory demyelination or neurodegeneration, to integrative dynamic models of brain reorganization, where, glia-neuron interactions, synaptic alterations and grey matter pathology are longitudinally envisaged at the whole-brain level. Functional and structural MRI can delineate network hallmarks for relapses, remissions or disease progression, …

Remodeling of Cortical Structural Networks in Multiple Sclerosis

2019

Multiple sclerosis (MS) is one of the most frequent immune-mediated disorders of the central nervous system. Pathological events occurring within the white matter and gray matter compartments can be reliably tracked in vivo by magnetic resonance imaging (MRI) but conventional imaging parameters do not reflect the remodeling processes of the brain. Here, we sought to investigate the reorganization of cortical structural networks in a group of patients with MS. For this, 40 patients (mean age ± standard deviation 31.2 ± 7.0 years, 14 males) with relapsing-remitting MS and 40 healthy subjects (27.1 ± 5.0 years, 14 males) were included in the study. From T1-weighted MR image-derived cortical th…
