Downregulation of miR-99a/let-7c/miR-125b miRNA cluster predicts clinical outcome in patients with unresected malignant pleural mesothelioma

Malignant pleural mesothelioma (MPM) is an aggressive tumor with a dismal overall survival (OS) and to date no molecular markers are available to guide patient management. This study aimed to identify a prognostic miRNA signature in MPM patients who did not undergo tumor resection. Whole miRNA profiling using a microarray platform was performed using biopsies on 27 unresected MPM patients with distinct clinical outcome: 15 patients had short survival (OS < 12 months) and 12 patients had long survival (OS > 36 months). Three prognostic miRNAs (mir- 99a, let-7c, and miR-125b) encoded at the same cluster (21q21) were selected for further validation and tested on publicly available miRNA sequencing data from 72 MPM patients with survival data. A risk model was built based on these 3 miRNAs that was validated by quantitative PCR in an independent set of 30 MPM patients. High-risk patients had shorter median OS (7.6 months) as compared with low-risk patients (median not reached). In the multivariate Cox model, a high-risk score was independently associated with shorter OS (HR=3.14; 95% CI, 1.18-8.34; P=0.022). Our study identified that the downregulation of the miR-99a/let-7/miR-125b miRNA cluster predicts poor outcome in unresected MPM

Le confessioni religiose tra libertà di vivere nella realtà dell'ordinamento statale e potere di creare norme giuridiche all'interno dello Stato. Il caso della Chiesa di Scientology.

L'A. si pone nella prospettiva di delineare il possibile significato della compresenza delle due distinte previsioni, l’una nell’art. 8, l’altra nell’art. 19 della Costituzione, a garanzia del fenomeno associativo religioso. La ricerca è stata redatta, fra l’altro, in considerazione della circostanza che, ad una prima sommaria lettura della Carta Costituzionale, il lettore potrebbe essere indotto a pensare che il fenomeno religioso, ed in particolare quello che si svolge in forma associata, goda di una maggiore preferenza, rispetto a quello che si esprime in forma individuale, per essere più volte disciplinato in Costituzione. Problema, questo, il quale non sembra abbia sinora ricevuto adeguato rilievo dalla dottrina ecclesiasticista che si è meritevolmente impegnata sul tema. Si è posto al riguardo l’interrogativo che nasce dalla presenza di due distinte previsioni costituzionali a garanzia del fenomeno associativo religioso: la prima contenuta nell’art. 8 il quale - com’è noto - regola con novità di linguaggio la posizione dei culti diversi dalla religione cattolica, garantisce alle confessioni religiose l’eguale libertà davanti alla legge, il diritto di organizzarsi secondo i propri statuti ed il potere di concludere intese con gli organi dello Stato; la seconda nell’art. 19 che riconosce la libertà di professare liberamente la propria fede religiosa in qualsiasi forma “individuale o associata”. In ordine ai numerosi problemi che la previsione costituzionale dell’art. 8 solleva, si è riflettuto soprattutto sul dubbio se la fattispecie in essa contemplata sia sostanzialmente ripetitiva e si risolva in un inutile duplicato di quanto disposto dall’art. 19 per la parte che riguarda tale aspetto, oppure se, con ciascuna di tali disposizioni, il legislatore costituzionale abbia voluto conferire uno specifico rilievo a due distinte sfere dell’esperienza giuridica con caratteristiche proprie, per struttura e sistemi di garanzie. L’analisi intrapresa ha interessato anche la ricostruzione della definizione giuridica di confessione religiosa, nonché l’accertamento del carattere confessionale della Chiesa di Scientology alla luce delle sentenze della giurisprudenza costituzionale e di legittimità

OBJECTIVETo present the nurse's integration within materials management of six teaching hospitals of Paraná - Brazil, and to describe the activities performed by nurses within this process.METHODA study of a qualitative approach and descriptive nature, conducted in teaching hospitals in Paraná, between June and August of 2013. The data collection was conducted through semi-structured interviews with eight nurses who worked in materials management; data were analyzed using content analysis.RESULTSThese showed that nurses perform ten categories of activities, distributed into four of the five steps of the materials management process.CONCLUSIONThe nurse, in performing of these activities, in addition to favoring the development of participative management, contributes to the organization, planning, and the standardization of the hospital supply process, giving greater credibility to the work with professionals who use the materials, and to the suppliers

Correlation of the score for subjective pain with physical disability, clinical and radiographic scores in recent onset rheumatoid arthritis

BACKGROUND: To analyse the relationship between subjective pain score and other measures of clinical, radiographic and functional status; in particular Larsen radiographic scores and Health Assessment Questionnaire (HAQ); in patients with severe rheumatoid arthritis (RA) with a disease duration of less than 3 years. METHODS: In this cross sectional study of 105 patients with RA (76 women, 29 men: mean age 50.93; mean disease duration 15.86 months; 71% rheumatoid factor positive) subjective pain was assessed according to the Visual Analog Scale (VAS). Correlation coefficients between pain score and disease activity measures (patients' global assessment of disease by VAS, number of tender and swollen joints, morning stiffness, erythrocyte sedimentation rate [ESR], C-reactive protein [CRP] and titre of rheumatoid factor, radiographic evaluations (Larsen-Dale scores for radiographic damage of the small joints of the hands, wrist and feet), disability measures (health assessment questionnaire [HAQ]), and demographic variables were calculated; hierarchical regression analysis was done with subjective pain score as the dependent variable. RESULTS: The Spearman's correlation coefficient comparing subjective pain and HAQ was 0.421 (p < 0.001), between subjective pain and global assessment of disease and morning stiffness was 0.573 (p < 0.001) and 0.427 (p < 0.001) respectively, and between pain and number of tender and swollen joints 0.037 and 0.050 respectively (p > 0.05). In regression analysis, global assessment of disease by patients explained 32.8% of the variation in pain intensity score, morning stiffness 10.7%, CRP 4.0%, HAQ 3.8% and Larsen-Dale scores explained 2.1%; other variables were not significant in the model. CONCLUSIONS: Pain scores of patients with early severe rheumatoid arthritis are correlated at higher levels with patients' global assessment of disease and with morning stiffness rather than with radiographic or other clinical variables such as number of tender and swollen joints

Measurement of the cross-section of high transverse momentum vector bosons reconstructed as single jets and studies of jet substructure in pp collisions at √s = 7 TeV with the ATLAS detector

This paper presents a measurement of the cross-section for high transverse momentum W and Z bosons produced in pp collisions and decaying to all-hadronic final states. The data used in the analysis were recorded by the ATLAS detector at the CERN Large Hadron Collider at a centre-of-mass energy of √s = 7 TeV;{\rm Te}{\rm V}$and correspond to an integrated luminosity of$4.6\;{\rm f}{{{\rm b}}^{-1}}$. The measurement is performed by reconstructing the boosted W or Z bosons in single jets. The reconstructed jet mass is used to identify the W and Z bosons, and a jet substructure method based on energy cluster information in the jet centre-of-mass frame is used to suppress the large multi-jet background. The cross-section for events with a hadronically decaying W or Z boson, with transverse momentum${{p}_{{\rm T}}}\gt 320\;{\rm Ge}{\rm V}$and pseudorapidity$|\eta |\lt 1.9$, is measured to be${{\sigma }_{W+Z}}=8.5\pm 1.7$ pb and is compared to next-to-leading-order calculations. The selected events are further used to study jet grooming techniques

Search for direct pair production of the top squark in all-hadronic final states in proton-proton collisions at s√=8 TeV with the ATLAS detector

The results of a search for direct pair production of the scalar partner to the top quark using an integrated luminosity of 20.1fb−1 of proton–proton collision data at √s = 8 TeV recorded with the ATLAS detector at the LHC are reported. The top squark is assumed to decay via t˜→tχ˜01 or t˜→ bχ˜±1 →bW(∗)χ˜01 , where χ˜01 (χ˜±1 ) denotes the lightest neutralino (chargino) in supersymmetric models. The search targets a fully-hadronic final state in events with four or more jets and large missing transverse momentum. No significant excess over the Standard Model background prediction is observed, and exclusion limits are reported in terms of the top squark and neutralino masses and as a function of the branching fraction of t˜ → tχ˜01 . For a branching fraction of 100%, top squark masses in the range 270–645 GeV are excluded for χ˜01 masses below 30 GeV. For a branching fraction of 50% to either t˜ → tχ˜01 or t˜ → bχ˜±1 , and assuming the χ˜±1 mass to be twice the χ˜01 mass, top squark masses in the range 250–550 GeV are excluded for χ˜01 masses below 60 GeV
