Il messianismo ebraico

Questa raccolta di saggi rappresenta un tentativo di evidenziare e analizzare la peculairità del messianismo ebraico: le sue fonti, la sua storia e i modi diversi e anche contraddittori in cui è stato recepito e attualizzato nel pensiero ebraico del Novecento. Nel Novecento, il messianismo ha svolto spesso una funzione di intensificazione di momenti prettamente filosofici - di filosofia della storia, per esempio - etici e politici, ma raramente, nei diversi pensatori che vi hanno attinto, si riscontra un'analisi approfondita o almeno accurata della tradizione religiosa e testuale da cui l'idea messianica trae origine

Automated classification of focal breast lesions according to S-detect: validation and role as a clinical and teaching tool

Abstract PURPOSE: To assess the diagnostic performance and the potential as a teaching tool of S-detect in the assessment of focal breast lesions. METHODS: 61 patients (age 21-84 years) with benign breast lesions in follow-up or candidate to pathological sampling or with suspicious lesions candidate to biopsy were enrolled. The study was based on a prospective and on a retrospective phase. In the prospective phase, after completion of baseline US by an experienced breast radiologist and S-detect assessment, 5 operators with different experience and dedication to breast radiology performed elastographic exams. In the retrospective phase, the 5 operators performed a retrospective assessment and categorized lesions with BI-RADS 2013 lexicon. Integration of S-detect to in-training operators evaluations was performed by giving priority to S-detect analysis in case of disagreement. 2\u2009 7\u20092 contingency tables and ROC analysis were used to assess the diagnostic performances; inter-rater agreement was measured with Cohen's k; Bonferroni's test was used to compare performances. A significance threshold of p\u2009=\u20090.05 was adopted. RESULTS: All operators showed sensitivity >\u200990% and varying specificity (50-75%); S-detect showed sensitivity >\u200990 and 70.8% specificity, with inter-rater agreement ranging from moderate to good. Lower specificities were improved by the addition of S-detect. The addition of elastography did not lead to any improvement of the diagnostic performance. CONCLUSIONS: S-detect is a feasible tool for the characterization of breast lesions; it has a potential as a teaching tool for the less experienced operators

HIPK2 Cooperates with KRAS Signaling and Associates with Colorectal Cancer Progression

Abstract Homeodomain-interacting protein kinase 2 (HIPK2) is an evolutionary conserved kinase that has gained attention as a fine tuner of multiple signaling pathways, among which those commonly altered in colorectal cancer. The aim of this study was to evaluate the relationship of HIPK2 expression with progression markers and mutational pattern and gain insights into the contribution of HIPK2 activity in colorectal cancer. We evaluated a retrospective cohort of colorectal cancer samples by IHC for HIPK2 expression and by next-generation sequencing (NGS) for the detection of mutations of cancer associated genes. We show that the percentage of HIPK2-positive cells increases with tumor progression, significantly correlates with tumor–node–metastasis (TNM) staging and associates with a worse outcome. In addition, we observed that high HIPK2 expression significantly associates with KRAS mutations but not with other cancer-related genes. Functional characterization of the link between HIPK2 and KRAS show that activation of the RAS pathway either due to KRAS mutation or via upstream receptor stimulation, increases HIPK2 expression at the protein level. Of note, HIPK2 physically participates in the active RAS complex while HIPK2 depletion impairs ERK phosphorylation and the growth of tumors derived from KRAS mutated colorectal cancer cells. Overall, this study identifies HIPK2 as a prognostic biomarker candidate in patients with colorectal cancer and underscores a previously unknown functional link between HIPK2 and the KRAS signaling pathway. Implications: Our data indicate HIPK2 as a new player in the complex picture of the KRAS signaling network, providing rationales for future clinical studies and new treatment strategies for KRAS mutated colorectal cancer. </jats:sec

Obstetric Outcomes in Women on Lithium: A Systematic Review and Meta-Analysis

Background/Objectives: Lithium taken during pregnancy was linked in the past with increased risk for foetal/newborn malformations, but clinicians believe that it is worse for newborn children not to treat the mothers&rsquo; underlying psychiatric illness. We set to review the available evidence of adverse foetal outcomes in women who received lithium treatment for some time during their pregnancy. Methods: We searched four databases and a register to seek papers reporting neonatal outcomes of women who took lithium during their pregnancy by using the appropriate terms. We adopted the PRISMA statement and used Delphi rounds among all the authors to assess eligibility and the Cochrane Risk-of-Bias tool to evaluate the RoB of the included studies. Results: We found 28 eligible studies, 10 of which met the criteria for inclusion in the meta-analysis. The studies regarded 1402 newborn babies and 2595 women exposed to lithium. Overall, the systematic review found slightly increased adverse pregnancy outcomes for women taking lithium for both the first trimester only and any time during pregnancy, while the meta-analysis found increased odds for cardiac or other malformations, preterm birth, and a large size for gestational age with lithium at any time during pregnancy. Conclusions: Women with BD planning a pregnancy should consider discontinuing lithium when euthymic; lithium use during the first trimester and at any time during pregnancy increases the odds for some adverse pregnancy outcomes. Once the pregnancy has started, there is no reason for discontinuing lithium; close foetal monitoring and regular blood lithium levels may obviate some disadvantages of lithium administration during pregnancy
