A real-world economic analysis of biologic therapies for psoriatic arthritis in Italy: results of the CHRONOS observational longitudinal study
2022
Abstract Background Psoriatic arthritis (PsA) is a chronic, immune-mediated, spondyloarthropathy characterised by musculoskeletal signs and symptoms with associated joint pain and tenderness. The average worldwide PsA prevalence is 133/100,000, while in the Italian population is 90–420/100,000. Traditionally, nonsteroidal anti-inflammatory drugs, glucocorticoid, and disease-modifying antirheumatic drugs have been used in the treatment of PsA. However, for those patients who are not adequately controlled with conventional therapies, the new biologics compounds represent a valid option. Biologic therapies have been shown to be more effective but also more expensive than conventional systemic …
Evolution of Cooperation Patterns in Psoriasis Research: Co-Authorship Network Analysis of Papers in Medline (1942–2013)
2015
BackgroundAlthough researchers have worked in collaboration since the origins of modern science and the publication of the first scientific journals in the eighteenth century, this phenomenon has acquired exceptional importance in the last several decades. Since the mid-twentieth century, new knowledge has been generated from within an ever-growing network of investigators, working cooperatively in research groups across countries and institutions. Cooperation is a crucial determinant of academic success.ObjectiveThe aim of the present paper is to analyze the evolution of scientific collaboration at the micro level, with regard to the scientific production generated on psoriasis research.Me…
SAT0656 DAPSA OR MDA/VLDA CRITERIA FOR DEFINING THE TREATMENT TARGET IN PSORIATIC ARTHRITIS? CROSS-SECTIONAL ANALYSIS FROM A MULTICENTER ITALIAN COHO…
2019
Background: According to international recommendations, psoriatic arthritis (PsA) should be managed by a treat-to-target approach, but the identification of the best tool for defining the target of remission/low disease activity (LDA) is still controversial. Objectives: To evaluate and compare the rates of remission/LDA by comparing Disease Activity in PSoriatic Arthritis (DAPSA) score with Very Low Disease Activity (VLDA)/Minimal Disease Activity (MDA) criteria in a real-life multicentre cohort of PsA patients. Methods: We performed a cross-sectional analysis including the first consecutive 500 PsA patients evaluated in 8 Italian rheumatology centres since September 2017. The rates of pati…
Overexpression of bone morphogenetic protein-6 (BMP-6) in the epidermis of transgenic mice: inhibition or stimulation of proliferation depending on t…
1996
Bone morphogenetic protein-6 (BMP-6) belongs to the family of TGF-beta-related growth factors. In the developing epidermis, expression of BMP-6 coincides with the onset of stratification. Expression persists perinatally but declines after day 6 postpartum, although it can still be detected in adult skin by reverse transcriptase-polymerase chain reaction (RT-PCR) analysis. We constitutively overexpressed BMP-6 in suprabasal layers of interfollicular epidermis in transgenic mice using a keratin 10 promoter. All mice expressing the transgene developed abnormalities in the skin, indicating an active transgene-derived factor. Depending on the pattern of transgene expression, the effects on proli…
Segregation of lipid in Ir-dye/DMPA mixed monolayers as strategy to fabricate 2D supramolecular nanostructures at the air–water interface
2008
A novel pseudospherical fluorinated iridium(III) derivative, Ir-dye/PF6, [Ir(F2-ppy)2(bpy)]PF6 (F2-ppy = 2-(2,4-difluoro)phenylpyridine, bpy = 2,2′-bipyridine), has been organized by using a lipid matrix, DMPA (dimyristoyl-phosphatidic acid), in several molar ratios at the air–water interface. The molecular organization of both components and the degree of miscibility in the different mixed films have been inferred by surface techniques such as π–A isotherms, ellipsometry, reflection spectroscopy, Brewster angle microscopy (BAM), and IR spectroscopy for the LB films, additionally the results have been discussed according to the additivity rule. The equimolecular Ir-dye/DMPA mixture leads to…
Sulfated Lupane Triterpene Derivatives and a Flavone C-Glycoside from Gypsophila repens
2007
A new sulfated lupane triterpene, Gypsophilin (1), and its glucosyl ester, Gypsophilinoside (2) were isolated from the roots of Gypsophila repens whereas a new flavone C-glycoside (3) was obtained from the aerial parts. Their structures were established as (3beta)-3-O-(sulfo)lup-20(29)-en-23,28-dioic acid (1), (3beta)-3-O-(sulfo)lup-20(29)-en-23,28-dioic acid -28-O-beta-D-glucopyranosyl ester (2) and luteolin-7-O-alpha-L-arabinopyranosyl-6-C-beta-glucopyranoside (3) by spectroscopic methods such as 1D and 2D NMR, HR-ESI-MS and FAB-MS.
Blue light irradiation suppresses dendritic cells activationin vitro
2013
Blue light is a UV-free irradiation suitable for treating chronic skin inflammation, for example, atopic dermatitis, psoriasis, and hand- and foot eczema. However, a better understanding of the mode of action is still missing. For this reason, we investigated whether dendritic cells (DC) are directly affected by blue light irradiation in vitro. Here, we report that irradiation neither induced apoptosis nor maturation of monocyte-derived and myeloid DC. However, subsequent DC maturation upon LPS/IFNγ stimulation was impaired in a dose-dependent manner as assessed by maturation markers and cytokine release. Moreover, the potential of this DC to induce cytokine secretion from allogeneic CD4 T …
Psoriātiska artrīta pacientu terapijas izvērtējums P.Stradiņa KUS Reimatoloģijas centrā
2016
Tēmas aktualitāte: pēdējos gados zinātniskās literatūras dati norāda par pētījumiem par NLR, PLR, MPV, CRO lietošanu psoriātiskā artrīta (PsA) pacientu slimības aktivitātes un terapijas efektivitātes novērtēšanā (Kim D.S. et all 2015), (Fu H. et all 2015), (Kisacik B. et all 2008), (Yazici S. et all 2010). Pētījuma mērķis: Izvērtēt PsA pacientu CRO, EGĀ, NLR, PLR un MPV rādītāju noteikšanas nepieciešamību ārstēšanas laikā. Metodes un materiāli: Pētījums izstrādāts P. Stradiņa KUS Reimatoloģijas centrā. Pētījumā iekļauti 39 pacienti, kuriem bija diagnosticēts PsA. PsA pacienti tika sadalīti divās grupās – pēc slimošanas ilguma, un pēc saņemtās terapijas. Šo grupu ietvaros analizējām CRO, EGĀ…
Premessa
2020
Premessa alla raccolta di studi intitolata "Le gipsoteche didattiche di arte e architettura a Palermo. Recupero, conservazione e fruizione delle collezioni di calchi in gesso"
La Gipsoteca del Dipartimento Culture e Società e il valore didattico delle raccolte di calchi in gesso di scultura antica
2020
The recent opening of the Plaster Cast Collection of the Department Cultures and Societies at the University of Palermo, after a long recovery and restoration work, is the starting point for some considerations about today’s possibilities of use of the academic plaster cast galleries of ancient sculpture. These collections, since their origin devoted to serve as a help for teaching the history of ancient art, and above all the Greek sculpture, are still worthy of interest. First of all they attest an important moment of the scientific history of the subject. But they can be also useful for the present study of ancient art, on condition that we are always aware of the functional and decontex…
