Abstract

Background and aim: Over 80% (365/454) of the nation’s centers participated in the Italian Society of Nephrology COVID-19 Survey. Out of 60,441 surveyed patients, 1368 were infected as of April 23rd, 2020. However, center-specific proportions showed substantial heterogeneity. We therefore undertook new analyses to identify explanatory factors, contextual effects, and decision rules for infection containment. Methods: We investigated fixed factors and contextual effects by multilevel modeling. Classification and Regression Tree (CART) analysis was used to develop decision rules. Results: Increased positivity among hemodialysis patients was predicted by center location [incidence rate ratio (IRR) 1.34, 95% confidence interval (CI) 1.20–1.51], positive healthcare workers (IRR 1.09, 95% CI 1.02–1.17), test-all policy (IRR 5.94, 95% CI 3.36–10.45), and infected proportion in the general population (IRR 1.002, 95% CI 1.001–1.003) (all p < 0.01). Conversely, lockdown duration exerted a protective effect (IRR 0.95, 95% CI 0.94–0.98) (p < 0.01). The province-contextual effects accounted for 10% of the total variability. Predictive factors for peritoneal dialysis and transplant cases were center location and infected proportion in the general population. Using recursive partitioning, we identified decision thresholds at general population incidence ≥ 229 per 100,000 and at ≥ 3 positive healthcare workers. Conclusions: Beyond fixed risk factors, shared with the general population, the increased and heterogeneous proportion of positive patients is related to the center’s testing policy, the number of positive patients and healthcare workers, and to contextual effects at the province level. Nephrology centers may adopt simple decision rules to strengthen containment measures timely.

Abstract

Garcinoic acid (GA or delta-T3-13'COOH), is a natural vitamin E metabolite that has preliminarily been identified as a modulator of nuclear receptors involved in beta-amyloid (Abeta) metabolism and progression of Alzheimer's disease (AD). In this study, we investigated GA's effects on Abeta oligomer formation and deposition. Specifically, we compared them with those of other vitamin E analogs and the soy isoflavone genistein, a natural agonist of peroxisome proliferator-activated receptor gamma (PPARgamma) that has therapeutic potential for managing AD. GA significantly reduced Abeta aggregation and accumulation in mouse cortical astrocytes. Similarly to genistein, GA up-regulated PPARgamma expression and apolipoprotein E (ApoE) efflux in these cells with an efficacy that was comparable to that of its metabolic precursor delta-tocotrienol and higher than those of alpha-tocopherol metabolites. Unlike for genistein and the other vitamin E compounds, the GA-induced restoration of ApoE efflux was not affected by pharmacological inhibition of PPARgamma activity, and specific activation of pregnane X receptor (PXR) was observed together with ApoE and multidrug resistance protein 1 (MDR1) membrane transporter up-regulation in both the mouse astrocytes and brain tissue. These effects of GA were associated with reduced Abeta deposition in the brain of TgCRND8 mice, a transgenic AD model. In conclusion, GA holds potential for preventing Abeta oligomerization and deposition in the brain. The mechanistic aspects of GA's properties appear to be distinct from those of other vitamin E metabolites and of genistein.

Abstract

Feline large granular lymphocyte (LGL) lymphoma is an uncommon subtype of lymphoma characterized by a grave prognosis and scarce response to chemotherapy. There are limited reports on clinico-pathological and prognostic factors. One-hundred and 9 cats with newly diagnosed LGL lymphoma that underwent initial staging (including hematology, serum biochemistry, thoracic radiographs and abdominal ultrasound), and followed-up were retrospectively evaluated. LGL lymphoma was localized within the gastrointestinal tract with or without extra-intestinal involvement in 91.7% of the cases, and at extra-gastrointestinal sites in 8.3%. Symptoms were frequent. Anemia (31.2%) and neutrophilia (26.6%) were commonly observed, and 14 (12.8%) cats had neoplastic circulating cells. Frequent biochemistry abnormalities included elevated ALT (39.4%) and hypoalbuminemia (28.4%). Twenty (54.1%) of 37 cats had elevated serum LDH. Treatment varied among cats, and included surgery (11%), chemotherapy (23%), corticosteroids (38.5%) and no treatment (27.5%). Median time to progression (MTTP) was 5 days, and median survival time (MST) 21 days. MST was significantly shorter in the case of substage b, circulating neoplastic cells, lack of chemotherapy administration, and lack of treatment response. A small subset of cats (7.3%) survived more than 6 months, suggesting that a more favorable clinical course can be found among LGL lymphoma patients.

Abstract

An increasing number of foreigners was observed in Italy even among chronic dialysis patients. We compared demographic, clinical, treatment characteristics and survival probability between groups of Italian and foreign patients with chronic dialysis in Lazio.We analysed data from the Lazio Dialysis and Transplantation Registry from 2004 to 2012 (4,076 prevalent chronic dialysis patients in 31-12-2012). Among 7,970 incident patients, we evaluated, by country of birth, survival probability by using Kaplan-Meier method and mortality risk, through multiple Cox regression.We observed an increase of foreigners among chronic dialysis patients in Lazio from 2004 (4.4%) up to 2012 (7.6%, test for trend: p0,001). Compared with Italians, foreign patients were younger (53.816.3 vs. 68.713.6) and more frequently: women (42.7% vs. 37.7%), HbsAg-positive (18.1% vs. 13.9%), not vaccinated if HBV susceptible (26.8% vs. 20.9%), late referral (21.6% vs. 12.9%) and suitable for kidney transplantation (21.7% vs. 9.9%). Foreigners compared with Italians had higher survival probability at 1 year (91.9% vs. 84.7%) and 5 years (74,6% vs. 51,5%) after chronic dialysis has been started. We observed a lower mortality risk (HR=0.71;IC95%:0.58-0.87) among foreign patients even after adjustment for many potential confounding factors. Our findings suggest that health status and treatment of end stage renal disease, including access to kidney transplantation, were similar between groups of Italian and foreign patients in Lazio. Observed differences in patients' characteristics were probably attributable to younger age of foreigners. However, further analyses are needed to fully explain higher survival probability in chronic dialysis among foreigners compared with Italians.

Abstract

The lexical coverage of the semantic database ItalWordNet has been extended by adding to the first nucleus of nouns and verbs, a set of adjectives and adverbs and also a set of Proper Names (PNs). Particular cases of polysemy were found in codifying PNs. Sense variation in PNs was verified in linguistic resources and new semantic relations were created in order to represent the sense extension phenomenon in the database. The relationship between the PNs present in IWN and the ontological classification of their belonging classes was highlighted: correspondence between sense variations and ontological variations was examined and the reference to the ontological structure of IWN was of help in recognizing many cases of PNs sense extension.

Abstract

Thesauri are tools which semantically organize a domain of knowledge for operational purposes. Their relational semantics is concerned with methods that connect terms with related meanings and it is important to support information retrieval, enhancing the information recall performance and contributing to improve precision. In fact, the network of relations of a thesaurus has an important semantic function, providing a representation of the meaning of each thesaurus term and a map of the conceptual structure of a subject area. The traditional thesaurus format - as described in international standards - includes the hierarchical, associative and equivalence relationships. However, a rather widespread opinion is that this format should be refined, in order to cope with the current needs of information organization. This paper discusses the possibility of refining the associative relation into a number of sub-kinds by adopting the semantic model of EuroWordNet (EWN), as it was used, according to one of its national versions, ItalWordNet (IWN), taking into account the terminological database Mariterm, which contains terms belonging to the maritime domain. It is also stressed how RT designation and refinement appear to be domain dependent, in the sense that they are associated with the specific features of a knowledge field.

Abstract

Particular uses of PNs with sense extension are focussed on and inspected taking into account the presence of PNs in lexical semantic databases and electronic corpora. Methodology to select ad include PNs in semantic databases is described; the use of PNs in corpora of Italian Language is examined and evaluated, analyzing the behaviour of a set of PNs in different periods of time. Computational resources can facilitate our study in this field in an effective way by helping codify, translate and handle particular cases of polysemy, but also guiding in metaphorical and metonymic sense recognition, supported by the ontological classification of the lexical semantic entities. The relationship between the "abstract" and the "concrete", which is at the basis of the Conceptual Metaphor perspective, can be considered strictly related to the variation of the ontological values found in our analysis of the PNs and their belonging classes which are codified in the ItalWordNet database.

Abstract

A research has been carried on and is still in progress aimed at the construction of three specialized lexicons organized as databases of relational type. The three databases contain terms belonging to the specialized knowledge fields of maritime terminology (technical-nautical and maritime transport domain), taxation law, and labour law with union labour rules, respectively. The EuroWordNet/ItalWordNet model was firstly used to structure the terminological database of maritime domain. The methodology experimented for its construction was applied to construct the next databases. It consists in i) the management of corpora of specialized languages and ii) the use of generic databases to identify and extract a set of candidate terms to be codified in the terminological databases. The three specialized resources are described highlighting the various kinds of lexical semantic relations linking each term to the others within the single terminological database and to the generic resources WordNet and ItalWordNet. The construction of these specialized lexicons was carried on in the framework of different projects; but they can be seen as a first nucleus of an organized network of generic and specialized lexicons with the purpose of making the meaning of each term clearer from a cognitive point of view.

Their relational semantics is concerned with methods that connect terms with related meanings and are designed to support information retrieval, namely enhancing the information recall performance and contributing to improve precision, too. The network of relations of a thesaurus has a semantic function: by means of it, in fact, a representation of the meaning of each thesaurus term is provided, as well as of the conceptual structure of a subject area. The traditional thesaurus format - as described in international standards - includes three basic relationships, two of them at a conceptual level, hierarchical and associative relations, the other mostly at a lexical level, relation of equivalence. However, a rather widespread opinion is that this format should be refined in order to cope with the current needs of information organization. This refinement is necessary to enhance thesaurus suitability for uses in artificial intelligence (AI) and in the Semantic Web environments, as well as to increase possibilities for IR. This paper discusses the possibility of refining the associative relation into a number of sub-kinds by adopting the semantic model of EuroWordNet (EWN), as it was used, according to one of its national versions, ItalWordNet (IWN), to structure a terminological resource for a specific domain. A number of issues that such a work of refinement could imply, and in particular its domain dependence, are also discussed.

Abstract

Based on the EuroWordNet/ItalWordNet model, a terminological database which contains terms belonging to the specialized lexicon of the maritime navigation and transport domain was created. Our lexicographic research aims to give prominence to the frequency of idiomatic expressions and metaphors used in everyday language that come from this cultural environment. This paper deals with a) idiomatic expressions and metaphors of the maritime domain which is considered as "source" domain, b) the use and the frequency of this type of idiomatic expressions and metaphors in a large corpus of Italian contemporary language, c) the semantic codification of metaphors and idiomatic expressions in the terminological database, d) the way the ontological structure of the database can help in metaphorical sense recognition.

Abstract

The users' demand has determined the need to manage the growing new technical maritime terminology which includes very different domains such as the juridical or commercial ones. A terminological database was built by exploiting the computational tools of ItalWordNet (IWN) and its lexical-semantic model EuroWordNet. This paper concerns the development of database structure and data coding, relevance of the concepts of 'term' and 'domain', information potential of the terms, complexity of this domain and detailed ontology structuring recently undertaken and still in progress. Our domain structure is described defining a core set of terms representing the two main sub-domains specified in 'technical-nautical' and 'maritime transport' terminology. These terms are sufficiently general to be the root nodes of the core ontology we are developing. They are mostly domain-dependent, but the link with the Top Ontology of IWN remains, endorsing either general and 'foundation' information, or detailed description directly connected with the specific domain. This structure seems to be the most appropriate to characterize the main conceptual schemas that people of the technical-nautical or maritime transport "world" actually use, namely activity plans, navigation management, etc. Also a set of acronyms has been codified to represent their ever increasing use in maritime terminology. Through the semantic relations linking the synsets, every term 'inherits' the IWN Top Ontology definitions and becomes itself an integral part of the structure. While codifying a term in the maritime database, the reference is at the same time allowed to the Base Concepts of the terminological ontology embedding the term in the semantic network, showing that upper and core ontologies make it possible for the framework to integrate different views on the same domain in a meaningful way.

Abstract

The paper reports on the creation of a terminological subset belonging to the maritime lexical domain; this set of terms is structured according to the design principles of the generic Italian lexical semantic database ItalWordNet, i.e. applying the same semantic relations model and using the possibility of linking the specialised terms to the corresponding closest concepts in WordNet. The main characteristics of the lexical semantic database are also described and, in particular: i) the construction of the terminological wordnet; ii) the approach adopted to connect the terminological database to the generic one; iii) some issues about the mapping between the Italian terms and the Princeton WordNet; iv) a first outline of a specific maritime domain ontology.

37. Metonymic and Metaphorical Uses of Proper Names

Abstract

In this paper we describe a research we are carrying out in the framework of ItalWordNet, a large lexical-semantic database containing semantic information for about 50,000 synsets of nouns, verbs, adjectives, adverbs, and a subset of proper names, which is continuously enriched and updated at the Institute for Computational Linguistics in Pisa. The research concerns the proper names considered from a twofold aspect: their coding in the lexical semantic database and their concrete use, as it is evidenced within a large corpus of the contemporary written Italian language. In particular the semantic relations involving the proper names and their senses (literal, derived and extended) are taken into consideration. Many proper names turn out to be the basis for many extensions of meaning, so in the paper we analyse in the corpus a set of them showing many types of derivates and sense extensions generated by means of lexical rules that operate as "generative factors" (Pustejovsky, 2001). The many contexts of use, analyzed in the corpus, confirm a rich regular polysemy regarding this category of nouns, so, for a set of cases, we propose to represent this phenomenon by introducing specific semantic relations in the database.

Abstract

This paper describes the main characteristics of the ItalWordNet semantic database, built in the context of the SI-TAL Italian National Project, within which a set of integrated resources and tools for the automatic treatment of the Italian language was realized. The database was created by extending the Italian wordnet developed within the EuroWordNet project, by adding: i) adjectives, adverbs and proper nouns (not dealt with in EuroWordNet); ii) a terminological subset related to the economic-financial domain. The relevant changes involved by these extensions both in the linguistic model and in the data structure are also illustrated. In particular, we discuss: i) the overall architecture of the database; ii) the semantic relations used to encode information on synsets; iii) the changes made to the EuroWordNet Top Ontology structure; iv) the specific characteristics of the terminological subset and the solutions adopted to link it to the generic wordnet.

Abstract

Over the last few years there has been much discussion about the relation between types of data, storage devices and system requirements for the preservation of data. This work carried out for the reorganization of the magnetic Archive of the Institute of Computational Linguistics (ILC), is an example of interaction between data management and recovery methods, as well as between data recording system development and evolution of storage devices. Data structure has also been affected by the technological evolution. It has been necessary to rely on an efficient, well-structured and tested data-base management system. Thus a computerized system was implemented for the joint management of normalized cataloguing files and bibliographic data, using the Information Retrieval System CDS/ISIS. A suitable description corresponding to standard criteria is necessary for a reliable tracing of the documents. The correct use of international standards like ISO to process traditional bibliographic information assures the accessibility, readability and consistency of the data.
