FSTL5 expression is a marker of Group C metastatic medulloblastomas
INTRODUCTION: Medulloblastoma (MB) is the most commonmalignant
brain tumor in children. Four different molecular subgroups are recognized,
which differ in gene expression, genomic aberrations, histology, demographics
and survival:WNT and SHH groups, having specific mutations in the homonymous
pathway, and groups C and D having several genetic alternations
not specific to a single pathway. The gene for follistatin-like protein 5, FSTL5,
is overexpressed in nonSHH/nonWNT MBs poorly characterized. Highexpression
of FSTL5 is significantly associated with reduced event-free and
overall survival in non-WNT/non-SHHMBs. The major aim of this project is
to study the FSTL5 expression level in pediatric MBs with metastasis at the
onset. METHOD: We investigated the protein expression of biomarkers involved
in metastatic pathways by IHC and FSTL5 expression level by
RT-PCR in 26 metastatic MBs samples and correlated these data with the outcomes
by Kaplan-Meier statistic analysis. RESULTS: 83% of Group C MBs
showed high level of FSTL5 while none of these presented down-expression.
Low-expression level of FSTL5 was find in 60% of SHH MBs and none
showed over-expression. Kaplan-Meier test revealed that, in our cohort, highexpression
ofFSTL5didnot correlatewithworse outcomewhile lowexpression
of FSTL5 was associated with good prognosis and the co-presence of FSTL5
with other biomarkers correlated with poorer prognosis. CONCLUSION:
FSTL5 is a marker of Group C in medulloblastomas with metastasis at the
onset and the results highlighted decreased FSTL5 expression as a marker of
good prognosis. Group C MBs have characteristic molecular features that
confirm the poorest outcome also inMBs with metastasis at the onset
El mantenimiento para las "Estaciones del Arte" en Nápoles
Las “Estaciones del Arte” nacen a partir de un proyecto promovido por la Administración Municipal de Nápoles, junto con la Empresa Metronapoli, para realizar un plan estratégico de fomento y localizar en la línea 1 el eje portador de la movilidad con la construcción de nuevas estaciones, que se convierten en ocasión de recualificación urbana para algunos puntos neurálgicos de la ciudad.
De las 34 estaciones del Sistema Metronapoli, 13 son aquellas definidas como “Estaciones del Arte”, 9 de la línea uno (Tab. 1) y 4 de la línea seis, diseñadas por: Óscar Tusquets Blanca, Karim Rashid, Atelier Mendini, Gae Aulenti, Domenico Orlacchio, Michele Capobianco y Renato Miano.
La propuesta de los proyectistas de acuerdo con el crítico de arte Achille Bonito Oliva, encargado por el Ayuntamiento de Nápoles de la dirección artística, ha transformado los espacios de tránsito de las estaciones en lugares de encuentro con el arte contemporáneo para los ciudadanos que diariamente utilizan las líneas 1 y 6. Se trata de una asignación insólita del arte, en un lugar de paso, definido a menudo como “non luogo” del transporte público, que se vuelve una escenografía de una operación cultural de gran envergadura, en la que se ven implicados los nombres más importantes del arte contemporáneo.
Con su patrimonio artístico compuesto por unas 200 obras realizadas por 95 artistas Metronapoli constituye un ejemplo único de museo descentrado y distribuido en el área urbana, que exprime el deseo de querer interactuar e integrarse con el territorio, contribuyendo no solamente a mejorar la movilidad urbana sino también a dar un valor adicional a la ciudad desde el punto de vista ético y estético, e incidiendo en el ámbito socio-cultural. Con este proyecto, el arte contemporáneo encuentra una amplia difusión en la capital de la región Campania desde el año 1995, cuando por entonces la administración promovió un proyecto denominado «gli Annali delle Arti» y otras iniciativas dirigidas a un público a menudo poco atraído por este género de arte.Tópico 2: Patrimonio Arquitectónico, Ingenieril y Arqueológico (urbano, rural, industrial, religioso, funerario).

The Role of Major Salivary Gland Ultrasound in the Diagnostic Workup of Sicca Syndrome: A Large Single-Centre Study
(1) Objective: To determine the diagnostic accuracy of major salivary gland ultrasonography (SGUS) in primary Sjogren's syndrome (SS), we used the Outcome Measures in Rheumatology Clinical Trials (OMERACT) scoring system on a large single-centre cohort of patients with sicca syndrome. (2) Method: We retrospectively collected the clinical, imaging and serological data of all the patients referred with a suspicion of SS who underwent SGUS and minor salivary glands biopsy. (3) Results: A total of 132 patients were included. The SGUS scores were correlated between the two sides (p < 0.001). The diagnostic cut-off for SS (AUROC: 0.7408) was 6 for the SGUS-global sum (sensitivity: 32.43%; specificity: 96.84%). The cut-off with the highest specificity for SS diagnosis was 7. In the patients with a final diagnosis of SS, the mean SGUS score was significantly higher (p < 0.001) than that of the non-SS patients (3.73 vs. 1.32 for the SGUS-global sum). A significant correlation was demonstrated between the SGUS scores and final SS diagnosis (p < 0.001), biopsy positivity (p < 0.001), ANA positivity (p = 0.016), Ro-SSA positivity (p = 0.01), and gland fibrosis (p = 0.02). (4) Conclusions: SGUS, using the OMERACT scoring system, has moderate sensitivity and high specificity for the diagnosis of SS. The scoring showed a strong and direct correlation with all the clinical hallmarks of SS diagnosis, such as the positivity of a labial salivary gland biopsy, ANA and Ro-SSA statuses, and salivary gland fibrosis. Because of its high specificity, a SGUS-global score > 6 could be therefore employed for the diagnosis of SS in the case of ANA negativity or the unavailability of a biopsy
Clinical, laboratory and ultrasonographic findings at baseline predict long-term outcome of polymyalgia rheumatica: a multicentric retrospective study : Polymyalgia rheumatica predicted by ultrasonographic findings polymyalgia rheumatica outcome predicted early by ultrasound
To assess the rate of PMR who, during the follow-up, undergo a diagnostic shift as well as to assess which clinical, laboratory and US findings are associated to a diagnostic shift and predict the long-term evolution of PMR. All PMR followed-up for at least 12 months were included. According to the US procedures performed at diagnosis, patients were subdivided into four subgroups. Clinical data from follow-up visits at 12, 24, 48 and 60 months, including a diagnostic shift, the number of relapses and immunosuppressive and steroid treatment, were recorded. A total of 201 patients were included. During the follow-up, up to 60% had a change in diagnosis. Bilateral LHBT was associated with persistence in PMR diagnosis, whereas GH synovitis and RF positivity to a diagnostic shift. Patients undergoing diagnostic shift had a higher frequency of GH synovitis, shoulder PD, higher CRP, WBC, PLT and Hb and longer time to achieve remission, while those maintaining diagnosis had bilateral exudative LHBT and SA-SD bursitis, higher ESR, lower Hb and shorter time to remission. Cluster analysis identified a subgroup of older patients, with lower CRP, WBC, PLT and Hb, lower PD signal or peripheral synovitis who had a higher persistence in PMR diagnosis, suffered from more flares and took more GCs. Most PMR have their diagnosis changed during follow-up. The early use of the US is associated with a lower dosage of GCs. Patients with a definite subset of clinical, laboratory and US findings seem to be more prone to maintain the diagnosis of PMR
An update of the evolving epidemic of blaKPC carrying Klebsiella pneumoniae in Sicily, Italy, 2014: Emergence of multiple Non-ST258 Clones
Background: In Italy, Klebsiella pneumoniae carbapenemase producing K. pneumoniae (KPC-Kp) strains are highly endemic and KPC producing CC258 is reported as the widely predominating clone. In Palermo, Italy, previous reports have confirmed this pattern. However, recent preliminary findings suggest that an epidemiological change is likely ongoing towards a polyclonal KPC-Kp spread. Here we present the results of molecular typing of 94 carbapenem non susceptible K. pneumoniae isolates detected during 2014 in the three different hospitals in Palermo, Italy. Methods and Results: Ninety-four consecutive, non replicate carbapenem non susceptible isolates were identified in the three largest acute general hospitals in Palermo, Italy, in the six-month period March-August 2014. They were characterized by PCR for β-lactam, aminoglycoside and plasmid mediated fluoroquinolone resistance genetic determinants. The mgrB gene of the colistin resistant isolates was amplified and sequenced. Clonality was assessed by pulsed field gel electrophoresis and multilocus sequence typing. Eight non-CC258 sequence types (STs) were identified accounting for 60% of isolates. In particular, ST307 and ST273 accounted for 29% and 18% of isolates. CC258 isolates were more frequently susceptible to gentamicin and non-CC258 isolates to amikacin. Colistin non susceptibility was found in 42% of isolates. Modifications of mgrB were found in 32 isolates. Conclusions: Concurrent clonal expansion of some STs and lateral transmission of genetic resistance determinants are likely producing a thorough change of the KPC-Kp epidemiology in Palermo, Italy. In our setting mgrB inactivation proved to substantially contribute to colistin resistance. Our findings suggest the need to continuously monitor the KPC-Kp epidemiology and to assess by a nationwide survey the possible shifting towards a polyclonal epidemic
Definitive childlessness in women with multiple sclerosis: a multicenter study
The frequency of definitive childlessness in women with multiple sclerosis (MS) may be higher than in the general population. MS may also affect decisions on the delivery procedure and on breast-feeding issues. Aim of the study was to assess the frequency of childlessness and its possible causes, the proportion of cesarean deliveries (CD), and the frequency of breast-feeding in patients and controls who have reached the end of their reproductive period. Female MS patients (>43 years) and controls (>45 years) filled out a questionnaire. We enrolled 303 patients and 500 controls. MS was associated with a higher frequency of childlessness (22 vs 13%) and less patients were in a stable relationship (83 vs 89%). There was no difference in the reported rates of infertility and miscarriages, while elective abortions were more frequent in patients (20 vs 12%). MS did not significantly affect the frequency of CD or of breast-feeding. MS-related reasons for childlessness, reported by 16% of childless patients, included disability/fear of future disability, fear of genetically transmitting MS, fear of not starting/discontinuing treatments, and discouragement by physician. Definitive childlessness is more frequent in women with MS compared to controls. A portion of voluntary childlessness may be avoided through correct/tailored information to patients
Diagnostic accuracy of OGUS, Southend halo score and halo count in giant cell arteritis
Objectives: Ultrasound has a paramount role in the diagnostic assessment of giant cell arteritis (GCA); Southend halo score (HS), halo count (HC), and OMERACT GCA Ultrasonography Score (OGUS) are the first quantitative scores proposed in this setting. The aim of this study was therefore to assess the diagnostic accuracy of these scores in a real-life scenario, as well as to evaluate their optimal cutoff, also with respect to disease extent, sex, and age. Methods: We retrospectively collected clinical, serological, and US findings of all patients referred for the first time to our vasculitis clinic in the suspicion of GCA. Results: A total of 79 patients were included, and a definite diagnosis of GCA was made in 43 patients. For OGUS, the ROC curve showed an optimal cut point of 0.81 (sensitivity 79.07% and specificity 97.22%). For HC and HS, the optimal cutoff values were > 1.5 (sensitivity 76.7% and specificity 97.2%) and > 14.5 (sensitivity 74.4% and specificity 97.2%), respectively. No relevant differences were assessed when patients were stratified according to disease extent, age, and sex. Compression sign (CS) was positive in 34 of 38 patients with cranial GCA and negative in all controls and LV-GCA. Conclusion: All three scores display good sensitivity and excellent specificity, although the cutoff was slightly different than proposed. In particular, for OGUS, a threshold of 0.81 could be employed for diagnostic purposes, although it was developed solely for monitoring. Due to its high sensitivity and specificity, CS should be always assessed in all patients referred with a suspicion of cranial GCA
Ultrasound description of cortical-entheseal bone remodeling in peripheral entheses of patients with psoriasis and nonspecific musculoskeletal symptoms
Aims: ultrasound (US) diagnosis of enthesitis is burdened of low specificity, especially when it is performed in patients with psoriasis (PsO) but without clinical psoriatic arthritis (PsA), because of mechanical, dysmetabolic and age-related concurrent enthesopatic changes. We propose a novel US score to quantify the cortical-entheseal bone remodeling burden of several peripheral entheses, aiming to improve the specificity of US for PsA-related enthesitis, and to evaluate its diagnostic value in PsO patients with subsequent diagnosis of psoriatic arthritis (PsO/PsA). Methods: clinical and US data of 119 consecutive patients with moderate/severe PsO and nonspecific musculoskeletal symptoms, were included in this retrospective study. PsO patients underwent a multi-joint US examination and a subsequent rheumatologic visit to evaluate concurrent PsA clinical diagnosis, in a scenario of real clinical practice. The cortical-entheseal bone remodeling has been evaluated with a morphologic gray-scale US score named “CERTUS” (Cortical-Entheseal Remodeling Tuscany Ultrasonographic Score, range 0-36), grading the combination of both enthesophytes and erosions in a semiquantitative scale. A variant of CERTUS, with Power Doppler (PD), was calculated too (CERTUS-PD, range 0-48), scoring PD signals into erosions. The sum of the scores obtained for 12 peripheral entheses was used as global score for statistic aims. The new bone formation at extensor tendon entheses at distal inter-phalangeal (DIP) joints were also recorded. Results: a clinical diagnosis of PsO/PsA was made in 48/119 PsO patients (40.3%), showing older age (p<0.001), higher BMI (p=0.015), prevalence of metabolic syndrome (p=0.014) and smoking habit (p<0.001). CERTUS (AUROC 0.814) showed a highest specificity cut-off=11 (sensitivity 41.4%, specificity 100%), whereas CERTUS-PD (AUROC 0.828) showed a highest specificity cut-off=13 (sensitivity 37.9%, specificity 100%). CERTUS and CERTUS-PD correlated with both other validated US scores as Belgrade Ultrasound Enthesitis Score (BUSES) (p<0.001), DACTylitis glObal Sonographic (DACTOS) score (p=0.05 and p=0.031 respectively), amount of synovitis (p=0.036 and p=0.04 respectively), enthesitis (p<0.001) and entheseal new bone formation on DIP joints (p=0.029 and p=0.031 respectively). Conclusions: the scoring system named CERTUS (and its variant with PD) is a quick tool to quantify cortico-entheseal bone remodeling burden in PsO patients, improving the specificity of US to diagnose patients with subclinical PsA-related enthesitis
Impact of age and cardiovascular risk factors on the incidence of adverse events in patients with rheumatoid arthritis treated with Janus Kinase inhibitors: data from a real-life multicentric cohort
Inhibiting Janus Kinases (JAK) is a crucial therapeutic strategy in rheumatoid arthritis (RA). However, the use of JAK inhibitors has recently raised serious safety concerns. The study aims to evaluate the safety profile of JAKi in patients with RA and identify potential risk factors (RFs) for adverse events (AEs). Data of RA patients treated with JAKi in three Italian centers from January 2017 to December 2022 were retrospectively analyzed. 182 subjects (F:117, 64.3%) underwent 193 treatment courses. 78.6% had at least one RF, including age >= 65 years, obesity, smoking habit, hypertension, dyslipidemia, hyperuricemia, diabetes, previous VTE or cancer, and severe mobility impairment. We identified 70 AEs (28/100 patients/year), among which 15 were serious (6/100 patients/year). A high disease activity was associated with AEs occurrence (p = 0.03 for CDAI at T0 and T6; p = 0.04 for SDAI at T0 and T6; p = 0.01 and p = 0.04 for DAS28ESR at T6 and T12, respectively). No significant differences in AEs occurrence were observed after stratification by JAKi molecules (p = 0.44), age groups (p = 0.08) nor presence of RFs (p > 0.05 for all of them). Neither the presence of any RFs, nor the cumulative number of RFs shown by the patient, nor age >= 65 did predict AEs occurrence. Although limited by the small sample size and the limited number of cardiovascular events, our data do not support the correlation between cardiovascular RFs-including age-and a higher incidence of AEs during JAKi therapy. The role of uncontrolled disease activity in AEs occurrence should by emphasized
