Magnetic resonance imaging and optical coherence tomography correlations in multiple sclerosis beyond anatomical landmarks.
2020
Abstract Objective To investigate multiple sclerosis (MS) optical coherence tomography (OCT) cross-sectional correlations with central nervous system (CNS) magnetic resonance imaging (MRI). Material and methods Peripapillary retinal nerve fiber layer (pRNFL), ganglion cell layer (GCL), inner plexiform layer (IPL), inner (INL) and outer nuclear layer (ONL) of 54 relapsing remitting (RRMS) and 38 progressive (PMS, 9 primary and 29 secondary) patients were measured. With less than 3 months brain parenchymal fraction (BPF), spinal cord (SC), total gray matter (GM) and white matter volumes were calculated. Demographical and clinical data was compared according to the history of optic neuritis (H…
A novel automated segmentation method for retinal layers in OCT images proves retinal degeneration after optic neuritis.
2015
Aim The evaluation of inner retinal layer thickness can serve as a direct biomarker for monitoring the course of inflammatory diseases of the central nervous system such as multiple sclerosis (MS). Using optical coherence tomography (OCT), thinning of the retinal nerve fibre layer and changes in deeper retinal layers have been observed in patients with MS. Here, we first compare a novel method for automated segmentation of OCT images with manual segmentation using two cohorts of patients with MS. Using this method, we also aimed to reproduce previous findings showing retinal degeneration following optic neuritis (ON) in MS. Methods Based on a 5×5 expansion of the Prewitt operator to efficie…
Comparison of the intestinal microbiome of italian patients with multiple sclerosis and their household relatives
2021
Multiple sclerosis (MS) is a chronic immune-mediated disease of the central nervous system, caused by a combination of genetic and environmental factors. In recent years, a role in MS pathogenesis was assigned to the gut microbiota. However, different signatures of gut dysbiosis have been shown to depend on environmental factors, like diet and lifestyle. In this study, we compared the gut microbiome in MS patients and their household healthy relatives sharing lifestyle and environmental factors. Faecal metagenomic DNA was extracted and the V3–V4 regions of the conserved bacterial 16S ribosomal RNA gene were amplified and sequenced. While overall bacterial communities were similar, specific …
Protein kinase CK2 governs the molecular decision between encephalitogenic T H 17 cell and T reg cell development
2016
T helper 17 (TH17) cells represent a discrete TH cell subset instrumental in the immune response to extracellular bacteria and fungi. However, TH17 cells are considered to be detrimentally involved in autoimmune diseases like multiple sclerosis (MS). In contrast to TH17 cells, regulatory T (Treg) cells were shown to be pivotal in the maintenance of peripheral tolerance. Thus, the balance between Treg cells and TH17 cells determines the severity of a TH17 cell-driven disease and therefore is a promising target for treating autoimmune diseases. However, the molecular mechanisms controlling this balance are still unclear. Here, we report that pharmacological inhibition as well as genetic ablat…
Unmet needs and gaps in the identification of secondary progression in multiple sclerosis: a Southern Italy healthcare professionals' perspective
2022
Abstract Objective Multiple sclerosis (MS) is a chronic disease with different clinical courses and a tendency to worsening. The relapsing–remitting MS presents acute onset and relapses of neurological symptoms, followed by their remission. This form can convert to secondary progressive MS (SPMS) with irreversible neurological worsening and disability. The identification of signs, symptoms, markers of progression, and strategies to manage MS patients is mandatory to allow early identification of those at higher risk of conversion to SPMS, for prompt intervention to cope with the progression of the disease. Methods A panel of Italian experts from Southern Italy have reviewed the current know…
Selected psychometric aspects of the Polish version of the Liverpool Self-efficacy Scale
2020
BackgroundSelf-efficacy expresses the individual’s belief in their ability to take up and continue actions in order to achieve a particular result and cope with various life events. For people with multiple sclerosis (MS), self-efficacy is an im-portant resource because it affects how they adapt to the disease, and influences their motivation, health-related behavior and physical activity. It also has a great impact on their quality of life. Because of the lack of tools for meas-uring self-efficacy in Polish patients with multiple sclerosis, the goal of the current study was to develop a Polish language version of the Liverpool Self-efficacy Scale (LSES) and assess its validity and reliabil…

MULTIPLE SCLEROSIS: PHYSICAL ACTIVITY AND WELL-BEING
2017
Multiple sclerosis (MS) is a chronic disease that affects central nervous system (CNS) – coexists in brain, spinal cord and optic nerves. It can process in three different courses: remitting, progressive and progressive-relapsing. Although there is still no cure for MS, effective strategies are available to modify the disease course, reduce number of relapses, rate of progressions and development of new lesions. Nowadays, moderate physical performance is strongly recommended: besides having positive effects on the body, it can have a positive effect on the psychophysical wellbeing. Essentially there are 3 types of training protocols: aerobic (endurance training), strength training (resistan…
RUOLO DELL’ESERCIZIO FISICO NELLA QUALITÀ DI VITA DI SOGGETTI CON SCLEROSI MULTIPLA. ROLE OF EXERCISE IN THE QUALITY OF LIFE IN SUBJECTS WITH MULTIPL…
2012
La sclerosi multipla è una patologia neurodegenerativa cronica che ha un impatto considerevole sullo stato fisico, psicologico e sociale dei pazienti, influenzando negativamente la loro qualità di vita. Tra i fattori contribuenti ad una ridotta qualità di vita sono inclusi la presenza di dolore, spasmi, sindromi depressive, l’aumento della fatica e la riduzione della forza muscolare, mobilità ed autonomia nella deambulazione. Accanto alla medicina convenzionale, varie forme di medicina complementare ed alternativa, tra cui l’esercizio fisico, sono utilizzate dai soggetti con sclerosi multipla. Tuttavia, poche sono le prove scientifiche a sostegno della loro efficacia nel ridurre i sintomi d…
