Il Bilancio d'esercizio delle società di calcio professionistiche. Il caso U.S. Città di Pontedera.

Da uno sguardo sull'evoluzione storico-giuridica del sistema calcio, all'analisi del bilancio delle società di calcio professionistiche passando attraverso la disciplina normativa a cui è sottoposta la redazione del principale strumento di comunicazione economico-finanziaria. Il lavoro svolto si propone di analizzare il bilancio delle società di calcio, evidenziandone le voci tipiche, con particolare attenzione alle società di provincia, nella fattispecie l'U.S. Città di Pontedera. Nell'ultima parte del lavoro si è cercato di valutare le scelte gestionali che hanno consentito alla società U.S. Città di Pontedera di presentare un bilancio "in salute", condizione confermata anche dalla comparazione con bilanci di altre società similari militanti nella stessa categoria

Rituximab suppresses disease activity after natalizumab withdrawal: an exploratory study

Background Natalizumab is highly effective in reducing multiple sclerosis disease activity; however it carries a risk of progressive multifocal leukoencephalopathy, that represents the main reason of drug discontinuation. After natalizumab withdrawal, reactivation of disease is soon observed and, until now, it is not known which treatment strategy should be followed after natalizumab discontinuation. Aim of this study is to evaluate rituximab efficacy in controlling disease activity after natalizumab withdrawal

Successful pregnancy and disease outcomes in a NMOSD patient treated with tocilizumab

Abstract Background Neuromyelitis Optica Spectrum Disorder (NMOSD) is an autoimmune relapsing disease involving the central nervous system with predominant inflammatory attack of optic nerves, spinal cord and area postrema, often leading to severe disability. Women with NMOSD typically experience adverse pregnancy outcomes and high relapse rates during pregnancy and the postpartum period. Case report Herein we present a case of pregnancy in a young NMOSD woman treated with tocilizumab. The course of her pregnancy was clinically unremarkable and treatment whit Tocilizumab was well tolerated. Conclusions This case raises the possibility that the modulation of immune system by inhibitors of the IL-6 pathway could a promising therapeutic option for pregnancy in NMOSD patient

Neutralizing antibodies against IFN‐β in multiple sclerosis: antagonization of IFN‐β mediated suppression of MMPs

Neutralizing antibodies (NAb) against interferon‐β (IFN‐β) develop in about a third of treated multiple sclerosis patients and are believed to reduce therapeutic efficacy of IFN‐β on clinical and MRI measures. The expression of the interferon acute‐response protein, myxovirus resistance protein A (MxA) is a sensitive measure of the biological activity of therapeutically applied IFN‐β and of its reduced bioavailability due to NAb. However, MxA may not be operative in the pathogenesis of multiple sclerosis or the therapeutic effect of IFN‐β. Instead, matrix metalloproteinases (MMPs) are increased in brain tissue, CSF and blood circulation of multiple sclerosis patients and function as effector molecules in several steps of multiple sclerosis pathogenesis. One of the molecular mechanisms by which IFN‐β exerts its beneficial effect in multiple sclerosis is reduction of MMP‐9 expression and increase of its endogenous tissue inhibitor, TIMP‐1. Quantitative PCR measurements of MMP‐2 and MMP‐9, TIMP‐1 and TIMP‐2, and MxA were performed in peripheral mononuclear cells from clinically stable multiple sclerosis patients with relapsing remitting disease course after short‐term and long‐term treatment with IFN‐β. IFN‐β therapy down‐regulated the expression of MMP‐9 and abolished that of MMP‐2 in long‐term, but not short‐term treated multiple sclerosis, while levels of MxA were increased in both instances. The presence of NAb reversed these effects, i.e. led to reduced MxA and increased MMP‐2/MMP‐9 expression levels compared with NAb- patients. In contrast, expression of TIMPs in peripheral blood mononuclear cells remained unaffected by IFN‐β therapy and the presence of NAb. While MxA is able to detect the biological action and reduced bioavailability of IFN‐β on the basis of single injections, only MMP‐9 shows quantitative correlation with the NAb titre. Together with evidence that an imbalance between MMP and TIMP expression is a crucial pathogenetic feature in multiple sclerosis, these findings support the concept of a significant role of NAb in reducing the therapeutic efficacy of IFN‐
