Positivity to p-ANCA in patients with status epilepticus
BACKGROUND: Status epilepticus (SE) may occur in the setting of several internal or neurologic diseases. Anti-neutrophilic cytoplasmic antibodies (ANCA) are a group of Ig that may be observed in patients with different autoimmune disorders but are particularly associated with systemic vasculitis named ANCA-associated-vasculities (AAV). We herein report 3 patients with SE and positivity to p-ANCA. CASE PRESENTATION: One patient had a catastrophic evolution and died 5Â months after disease onset. The other two patients had a good outcome and remained seizure-free at 30Â months and 5Â years of follow-up respectively. CONCLUSION: This report highlights the importance of considering ANCA dosage in patients with SE of unclear origin
Involvement of fractalkine and macrophage inflammatory protein-1 alpha in moderate-severe depression.
Moderate-severe depression (MSD) is linked to overexpression of proinflammatory cytokines and chemokines. Fractalkine (FKN) and macrophage inflammatory protein-1 alpha (MIP-1alpha) are, respectively, members of CX3C and C-C chemokines, and both are involved in recruiting and activating mononuclear phagocytes in the central nervous system. We analysed the presence of FKN and MIP-1alpha in sera of untreated MSD patients and healthy donors. High FKN levels were observed in all MSD patients as compared with values only detectable in 26% of healthy donors. MIP-1alpha was measurable in 20% of patients, while no healthy donors showed detectable chemokine levels. In conclusion, we describe a previously unknown involvement of FKN in the pathogenesis of MSD, suggesting that FKN may represent a target for a specific immune therapy of this disease
Brivaracetam as Early Add-On Treatment in Patients with Focal Seizures: A Retrospective, Multicenter, Real-World Study
Introduction In randomized controlled trials, add-on brivaracetam (BRV) reduced seizure frequency in patients with drug-resistant focal epilepsy. Most real-world research on BRV has focused on refractory epilepsy. The aim of this analysis was to assess the 12-month effectiveness and tolerability of adjunctive BRV when used as early or late adjunctive treatment in patients included in the BRIVAracetam add-on First Italian netwoRk Study (BRIVAFIRST). Methods BRIVAFIRST was a 12-month retrospective, multicenter study including adult patients prescribed adjunctive BRV. Effectiveness outcomes included the rates of sustained seizure response, sustained seizure freedom, and treatment discontinuation. Safety and tolerability outcomes included the rate of treatment discontinuation due to adverse events (AEs) and the incidence of AEs. Data were compared for patients treated with add-on BRV after 1-2 (early add-on) and >= 3 (late add-on) prior antiseizure medications. Results A total of 1029 patients with focal epilepsy were included in the study, of whom 176 (17.1%) received BRV as early add-on treatment. The median daily dose of BRV at 12 months was 125 (100-200) mg in the early add-on group and 200 (100-200) in the late add-on group (p < 0.001). Sustained seizure response was reached by 97/161 (60.3%) of patients in the early add-on group and 286/833 (34.3%) of patients in the late add-on group (p < 0.001). Sustained seizure freedom was achieved by 51/161 (31.7%) of patients in the early add-on group and 91/833 (10.9%) of patients in the late add-on group (p < 0.001). During the 1-year study period, 29 (16.5%) patients in the early add-on group and 241 (28.3%) in the late add-on group discontinued BRV (p = 0.001). Adverse events were reported by 38.7% and 28.5% (p = 0.017) of patients who received BRV as early and late add-on treatment, respectively. Conclusion Brivaracetam was effective and well tolerated both as first add-on and late adjunctive treatment in patients with focal epilepsy
Alterations in the α2 Ύ ligand, thrombospondin-1, in a rat model of spontaneous absence epilepsy and in patients with idiopathic/genetic generalized epilepsies
Objectives
Thrombospondins, which are known to interact with the α2Ύ subunit of voltage-sensitive calcium channels to stimulate the formation of excitatory synapses, have recently been implicated in the process of epileptogenesis. No studies have been so far performed on thrombospondins in models of absence epilepsy. We examined whether expression of the gene encoding for thrombospondin-1 was altered in the brain of WAG/Rij rats, which model absence epilepsy in humans. In addition, we examined the frequency of genetic variants of THBS1 in a large cohort of children affected by idiopathic/genetic generalized epilepsies (IGE/GGEs).
Methods
We measured the transcripts of thrombospondin-1 and α2Ύ subunit, and protein levels of α2Ύ, Rab3A, and the vesicular glutamate transporter, VGLUT1, in the somatosensory cortex and ventrobasal thalamus of presymptomatic and symptomatic WAG/Rij rats and in two control strains by real-time polymerase chain reaction (PCR) and immunoblotting. We examined the genetic variants of THBS1 and CACNA2D1 in two independent cohorts of patients affected by IGE/GGE recruited through the Genetic Commission of the Italian League Against Epilepsy (LICE) and the EuroEPINOMICS-CoGIE Consortium.
Results
Thrombospondin-1 messenger RNA (mRNA) levels were largely reduced in the ventrobasal thalamus of both presymptomatic and symptomatic WAG/Rij rats, whereas levels in the somatosensory cortex were unchanged. VGLUT1 protein levels were also reduced in the ventrobasal thalamus of WAG/Rij rats. Genetic variants of THBS1 were significantly more frequent in patients affected by IGE/GGE than in nonepileptic controls, whereas the frequency of CACNA2D1 was unchanged.
Significance
These findings suggest that thrombospondin-1 may have a role in the pathogenesis of IGE/GGEs
La forme financiarisĂ©e de la relation de crĂ©dit des collectivitĂ©s locales. De la crise Ă lâinstitutionnalisation
La thĂšse porte sur les Ă©volutions de la relation de crĂ©dit des collectivitĂ©s locales et Ă©tudie les diffĂ©rentes formes que celle-ci a pu prendre au cours du temps. Elle dĂ©veloppe une approche institutionnaliste oĂč la relation de crĂ©dit et ses transformations historiques sont saisies Ă partir des rĂ©gulations qui encadrent, au niveau institutionnel et de maniĂšre plus ou moins lĂąche, la demande de crĂ©dit Ă©manant des collectivitĂ©s locales, dâune part, et lâoffre de crĂ©dit des acteurs financiers, dâautre part. Tout particuliĂšrement, sur la pĂ©riode rĂ©cente, elle met en Ă©vidence lâĂ©mergence et lâinstitutionnalisation dâune « forme financiarisĂ©e », caractĂ©risĂ©e par lâutilisation de produits financiers distribuĂ©s sur les marchĂ©s financiers dans la gestion de dette des collectivitĂ©s locales.The thesis focuses on the evolutions of local authoritiesâ credit relationship and studies the various forms it has taken over time. It develops an institutionnalist approach in which credit relationship, and its historical transformations, are captured from the regulations that frame, more or less loosely, the credit demand from local authorities on the one hand, and the credit supply of financial actors on the other. More particularly, and over the recent period, the thesis highlights the emergence and the institutionnalization of what I identify as a âfinancialized formâ, characterized by the use of financial products, made available by financial markets, in local authoritiesâ debt management
Benjamin Lemoine, Lâordre de la dette. EnquĂȘte sur les infortunes de lâĂtat et la prospĂ©ritĂ© du marchĂ©
Benjamin Lemoine propose dans cet ouvrage de mettre en cause lâĂ©vidence de la dette de lâĂtat telle quâelle est dĂ©sormais connue, Ă savoir comme des titres financiers dont les taux dâintĂ©rĂȘt sâimposent aux Ătats. Les dĂ©bats publics ne questionnent plus cette forme de financement mais vĂ©hiculent une vision pathologique de la dette quâil faudrait rĂ©duire au plus vite. Le premier constat rĂ©alisĂ© consiste ainsi Ă souligner cet Ă©cart entre une technique de financement de lâĂtat, exclue des dĂ©bats,..
Dexia, ou la faillite dâune rĂ©gulation du crĂ©dit local par le marchĂ©
Caught in the torment of the 2008 and the 2011 financial crises, Dexia, the historical lender to local government, was saved from bankruptcy by the Belgian and French states late in 2011. The paper looks back on the genesis of this rescue by developing an historical and institutionalist perspective of changes in local government borrowing and its regulation by the state. It sheds light on the changeover from administered regulation â where central government as from the 1950s strictly shaped supply and demand for credit in its own interest â to market-based regulation â when the state withdrew from local government lending in the 1980s. Once state-controlled, Dexia was privatized in 1993 and embarked on a strategy directed at the financial markets. That strategy collapsed in 2008, requiring state intervention of last resort to avoid contagion spreading to the financial system and a credit crunch for local government. Having created market-based regulation of local government borrowing in the 1980s, it was left to the state to âfoot the billâ for the excesses of market regulation
The financialized form of the French local authorities' credit relationship. From the crisis to institutionnalization.
La thĂšse porte sur les Ă©volutions de la relation de crĂ©dit des collectivitĂ©s locales et Ă©tudie diffĂ©rentes formes que celle-ci a pu prendre au cours du temps. Tout particuliĂšrement, sur la pĂ©riode rĂ©cente, nous mettons en Ă©vidence lâĂ©mergence et lâinstitutionnalisation de ce que nous identifions comme une « forme financiarisĂ©e », caractĂ©risĂ©e par lâutilisation de produits financiers distribuĂ©s sur les marchĂ©s financiers dans la gestion de dette des collectivitĂ©s locales. Nous dĂ©veloppons une approche institutionnaliste oĂč la relation de crĂ©dit, et ses transformations historiques, sont saisies Ă partir des rĂ©gulations qui encadrent, de maniĂšre plus ou moins lĂąche, la demande de crĂ©dit Ă©manant des collectivitĂ©s locales, dâune part, et lâoffre de crĂ©dit des acteurs financiers, dâautre part. Nous cherchons notamment Ă rendre compte de la maniĂšre dont les interactions entre demande et offre de crĂ©dit sont conditionnĂ©es et en partie dĂ©terminĂ©es au niveau institutionnel. Deux types de pratiques dâemprunts que nous qualifions de financiarisĂ©s sont au centre de ce travail : lâemprunt structurĂ© et lâemprunt obligataire. Nous suivons le dĂ©veloppement Ă partir des annĂ©es 1990 des produits structurĂ©s qui seront au centre de la crise des emprunts dits « toxiques », ainsi que les formes de gestion puis de sortie de cette crise (2004-2015). Sur la mĂȘme pĂ©riode, des Ă©missions obligataires groupĂ©es de collectivitĂ©s locales sont dĂ©veloppĂ©es et vont dĂ©boucher sur la crĂ©ation de lâAgence France Locale (AFL), dont nous suivons la structuration (2004-2018). Nous montrons que la pĂ©riode dâincertitude qui sâouvre Ă compter de la crise financiĂšre de 2008 contribue paradoxalement Ă la poursuite et lâinstitutionnalisation du recours, pour les collectivitĂ©s locales, Ă des produits faisant appel aux marchĂ©s et investisseurs financiers. Ce rĂ©sultat nâĂ©tait pas Ă©crit dans la mesure oĂč la crise des emprunts toxiques nourrit une vive critique dâune forme financiarisĂ©e qui sâĂ©tait dĂ©veloppĂ©e « par le bas » dans un contexte de libĂ©ralisation financiĂšre pour le prĂȘt aux collectivitĂ©s locales et de dĂ©centralisation. Le moment de rĂ©flexion institutionnelle, qui sâouvre avec la crise, conduit les acteurs Ă tenter de dissocier la « mauvaise » finance de la « bonne » pour mieux pouvoir continuer Ă recourir Ă des formes dâemprunt financiarisĂ©es. LâenquĂȘte par entretiens (n= 61) et la collecte dâune abondante littĂ©rature grise se sont organisĂ©es principalement autour du dĂ©cryptage des outils de gestion, dispositifs de gestion de crise et rĂ©glementations qui structurent la relation de crĂ©dit. Nous les dĂ©codons sous lâangle des conventions quâils incorporent et des prĂ©supposĂ©s quâils rendent lĂ©gitimes, ce qui nous permet dâen souligner les effets de sĂ©lection et de disciplinarisation. En ce qui concerne lâemprunt structurĂ©, ce travail est complĂ©tĂ© par une analyse statistique et Ă©conomĂ©trique portant sur les communes « intoxiquĂ©es » et permettant de discuter des dĂ©terminants du dĂ©veloppement du recours Ă ce type dâemprunt.The thesis focuses on the evolutions of local authoritiesâs credit relationship and studies the various forms it has taken over time. More particularly, and over the recent period, the thesis highlights the emergence and the institutionnalization of what I identify as a âfinancialized formâ, characterized by the use of financial products, made available by financial markets, in local authoritiesâdebt management. The thesis develops an institutionnalist approach in which credit relationship, and its historical transformations, are captured from the regulations that frame, more or less loosely, the credit demand from local authorities on the one hand, and the credit supply of financial actors on the other. The paper aims especially to investigate the ways in which interplays between credit demand and supply are conditioned and partly determined at an institutional level. Two types of debt practices that this paper identifies as âfinancializedâ are at the core of this work : structured debt and bond debt. The thesis follows the development, from the 1990âs onwards, of structured loans which played a key role in the âtoxix loan crisisâ, as well as the subsequent management and resolution of that crisis (2004-2015). Over the same period, local authoritiesâ joint bonds issues became organized and led to the creation of Agence France Locale, the structuring of which is described in this thesis (2004-2018). The period of incertainty, following the 2008 financial crisis, has seen paradoxically the continuation and the institutionnalization of the use, by local authorities, of financial products that were appealing to markets and financial investors. This result was not given insofar as the toxic loans crisis led to a strong critique of the âfinancialized formâ (which has spread âfrom the bottomâ, within a context of financial liberalization of local authoritiesâ loans and of decentralization). The post-crisis institutionnal thinking led the actors to attempt to dissociate âbadâ finance from âgoodâ finance in order to have better access to financialized forms of debt. The interview-based survey (n=61) and the collection of an abundant grey literature were organised mainly around the decoding of management tools, crisis management devices and regulations which structure local authoritiesâ credit relationship. The thesis decodes them from the perspective of the conventions they incorporate and the premises which make them look legitimate, and this allows us to emphasize their effects of selection and disciplining. With regard to structured loans, the research is supplemented with a statistical and econometric analysis which focused on the municipalities which have fallen intro the trap of toxic loans, which enables a discussion of the determinants in the development of this type of loan
