How immigration can change the prevalence of HBV infection in an urban area of Northern Italy
Massimo De Paschale,Maria Teresa Manco,Luisa Belvisi,Carlo Magnani
Microbiology Research , 2011, DOI: 10.4081/mr.2011.e21
Abstract: The introduction of HBV vaccination in Italy has led to a decline in new HBV infections. Increasing immigration over recent years suggests a change in short-term epidemiology of HBV. The aim of this study was to assess the prevalence of HBV infection in the general population living in the catchment area of Legnano Hospital (Northern Italy). In the period 2007-2008, 22,758 inpatients and outpatients were examined for Hepatitis B surface antigen (HBsAg), of whom 1,654 (7.3%) were of foreign origin. Of the 488 patients who were positive for HBsAg (2.1%), 381 (1.8%) were Italian and 107 (6.5%) were born in other countries. In terms of age, the prevalence of HBsAg was significantly higher among non- Italians in every age group (other than those aged >60 and <11 years), and in many of the selected subgroups: the inpatients of some departments (35.4% vs 17.2%), pregnant women (5.3% vs 0.3%), blood donors (4.7% vs 0.1%), and hospital staff (6.4% vs 1.3%). Non- Italians were affected by 16.7% of acute infections and 24.3% of chronic infections; they also accounted for 42.6% of subjects with carrier state, 16.0% of patients with chronic hepatitis, and 12.2% of patients with cirrhosis. In our area, the overall prevalence of HBsAg among Italians is less than 2% (as expected following the introduction of HBV vaccination), but it is significantly higher among patients from areas highly endemic for HBV infection who represent a new reservoir for HBV infection.

Infectious Disease Reports , 2012, DOI: 10.4081/idr.2012.e17
Abstract: Various countries have implemented anti-rubella vaccination campaigns with the main aim of preventing congenital infection. In 2003, Italy joined the European WHO programme for the elimination of congenital rubella and issued a special healthcare plan, one of the objectives of which was to reduce the proportion of rubella-susceptible pregnant women to less than 5% by 2005. The aim of this study was to determine the percentage of seronegative pregnant women after the implementation of this plan. Anti-rubella IgG and IgM antibodies were sought in 2385 pregnant women who attended our hospital for serological screening between 1 July 2008 and 30 June 2010. They included 750 women of foreign origin (31.4%). Eight percent of the women were anti-rubella seronegative: 6.2% of the Italians and 11.7% of the non-Italians. Among the women of foreign origin, the percentage of seronegativity ranged from 5.6% of those coming from Eastern Europe to 17.7% of those coming from Latin America. The level of seropositivity among women of Italian origin is high, although the objective of ensuring less than 5% of susceptible pregnant women has not yet been quite reached in our area. However, particular attention needs to be given to women coming from geographical areas characterised by different epidemiologies and vaccination strategies because the percentage of seronegativity is in some cases double that of Italian women.

Abstract: The fetal consequences of CMV infection make it one of the most serious infections contracted during pregnancy, but the scientific community is divided over the proposed implementation of preventive screening for anti-CMV antibodies. The aim of this study was to assess the incidence and risk of infection during pregnancy in 2817 women who underwent anti-CMV IgG and IgM antibody screening during the period 2005–2007. The prevalence of anti-CMV IgG antibodies was 68.3% (95% CI: 66.6–70.0); the seroconversion rate in the 892 seronegative women was 0.32%; the results of IgG avidity testing revealed an cumulative incidence of 1.4% (95% CI: 0.97–1.83), density incidence of 0.8% (as cases/pregnant woman-trimester) (95% CI: 0.47–1.13), and a risk of infection of 0.5% (95% CI: 0.24–0.76). The screening identified 13 cases of primary infection (84.6% of which occurred in the first trimester of pregnancy). The possibility to identify these cases and consequently to plan appropriate interventions, supports the use of screening during pregnancy, especially in the first trimester when the risk of infection is greater.
Search for Anti-EA(D) Antibodies in Subjects with an “Isolated VCA IgG” Pattern

International Journal of Microbiology , 2010, DOI: 10.1155/2010/695104
Abstract: The presence of an “isolated viral capsid antigen (VCA) IgG” pattern in serum is not easy to interpret without the aid of further tests, such as specific immunoblotting or a virus genome search, that often give rise to organisational and economic problems. However, one alternative is to use an enzyme-linked immunosorbent assay (ELISA) to detect anti-early antigen (EA) antibodies, which can be found in about 85% of subjects with acute Epstein-Barr virus (EBV) infections. The purpose of this work was to search for anti-EA(D) antibodies in 130 samples with an isolated VCA IgG pattern at ELISA screening and classified as being indicative of past (102 cases) or acute (28 cases) infection on the basis of the immunoblotting results. Thirty-seven samples (28.5%) were positive for anti-EA(D), of which 25 (89.3%) had been classified by immunoblotting as indicating acute and 12 (11.8%) past EBV infection. This difference was statistically significant (<.01). The results of our search for anti-EA(D) antibodies correctly identified nearly 90% of acute (presence) or past EBV infections (absence). When other tests are not available, the search for anti-EA antibodies may therefore be helpful in diagnosing patients with an isolated VCA IgG pattern at screening tests.

Introduction The most common manifestation of primary Epstein-Barr virus (EBV) infection is acute infectious mononucleosis, a self-limited clinical syndrome that most frequently affects adolescents and young adults. Serology is one of the cardinal means of diagnosing EBV infection as antibody search for viral capsid antigen (VCA), nuclear antigen (EBNA), and early antigen (EA) makes it possible to define the status of the infection [1, 2]. The three parameters of VCA IgG, VCA IgM, and EBNA-1 IgG generally make it simple to distinguish acute and past infection in immunocompetent patients [3]. The presence of VCA IgG and VCA IgM in the absence of EBNA-1 IgG is indicative of acute infection, whereas the presence of VCA IgG and EBNA-1 IgG in the absence of VCA IgM is typical of past infection. However, the presence of an isolated VCA IgG pattern may appear in about 8% of all subjects with at least one EBV infection marker [4] and may be difficult to interpret because it can be found in patients with prior infection as well as in those with acute infection. In fact, in some cases, VCA IgM may appear 1-2 weeks after VCA IgG, or for a very short time, or at such a low concentration as to be missed by conventional laboratory tests [5]; furthermore, VCA IgM may persist for a long time after acute infection and still

Sociology Mind (SM) , 2012, DOI: 10.4236/sm.2012.21015
Abstract: According to the Lisbon strategy for a knowledge society, entering school plays a significant role for any young immigrant. In Belgium, this issue is very worrying, as equity between native born students and those of foreign origin seems to be lacking. Finally, the situation in French-speaking Belgium is even more difficult than in the Flemish part of the country. Also, this paper aims to explore the strategies in place to welcome and integrate these children. It portrays specific guidance devices for young newcomers and analyzes possible correlations between them and the rate of academic success. In light of particularities of the Belgian educational system especially linked to the fact that we are in a federal state with different languages of reference, our study covers the portion of the federal state where French is the official language. The targeted group is that of newcomers of age to attend secondary school. The method of analysis and synthesis of available information includes both quantitative and qualitative data. Our approach was based on the description and analysis of the context of recognition and knowledge acquisition of young students of foreign origin in secondary education. Our analysis focuses on: accessibility to education and equality of success; adequacy to requirements, consistency and efficiency, as well as effectiveness of the education system; the relevance and specific training of teachers adapted to the newcomers; sustainability of the results: the insertion and future integration of youth; and finally, various linguistic, social and psychological dimensions, as well as citizenship. The report identifies some key elements of the context of schooling for young newcomers and offers brief elements of understanding of the history of immigration in this region. Specific and general practices for integration and schooling of young migrants, including accompanied or unaccompanied minor asylum seekers, are described. Finally, these elements are analyzed in terms of accessibility standards to school education, criteria for adequacy of such education to the specificity of immigrant children and finally, criteria for system effectiveness, and practical tracks are proposed.
Legal Concepts and Multilingual Contexts in Digital Information  [PDF]
Daniela Tiscornia, Maria Teresa Sagri
Beijing Law Review (BLR) , 2012, DOI: 10.4236/blr.2012.33010
Abstract: Analysis of legal documents cannot be reduced to their linguistic expression. When dealing whit legal texts a distinction should be made between the linguistic form (normative statement) and the content (norm). Norms are conceived as the interpreted meaning of linguistic contexts (partitions in a legal text, fragments of judicial decisions, etc). In the interpretative process, legal practitioners make reference to an external system of concepts that can be assumed, even if not universal, at least shared by a large social and cultural community. As a consequence, legal interpretation and legal conceptualization are strongly influenced by cultural, social and political factors and changes in meaning of legal concepts occur within a synchronic localization in different cultures and within a diachronic evolution process of the environment in which they are created. This dynamic nature of legal knowledge poses serious problems in communicating legal information, and even more in the realm of digital communication, where, in order to manage knowledge across national borders, there is a strong demand of shared vocabularies embedding a shared understanding of legal concept. This paper aims at showing how lexical/terminological resources and conceptual structures, such as ontologies, can be constructed by means of the innovative tools provided by ICT, like the Semantic Web languages, the computational linguistic and the ontology engineering techniques. Such semantic resources may have a strategic role in representing meaning evolution and in investigating social and cultural influences in linguistic uses and, as a further goal, solutions offered by ICT for bridging the gap between form and content can also provide innovative visions of theoretical issues.
Open Mass Cultures of Marine Microalgae for Biodiesel Production: Laboratory Approach to Study Species Competition in Mixed Cultures  [PDF]
Marina Mingazzini, Maria Teresa Palumbo
Natural Resources (NR) , 2015, DOI: 10.4236/nr.2015.63016
Abstract: Since the interspecific competition represents a critical issue for biodiesel production in open mass cultures of microalgae, laboratory studies aimed to select competitive species receive significant interest. In this work, a laboratory approach based on the method of multisizing cell counting was developed to monitor the competition course of single algal species grown in mixed cultures. Two marine microalgae, Dunaliella tertiolecta and Phaeodactylum tricornutum, were used to set-up an induced-contamination assay, with the aim to test their competitive capabilities. The evaluation of the oil production by dried biomass extraction was coupled to the growth assay to investigate the effect of competition on oil yield. The adopted experimental approach revealed effective as a method to selectively measure the algal growth of single species in mixed cultures, enabling to evaluate the competitive properties of Dunaliella outgrowing the contaminant species Phaeodactylum. At the end of the experiment the dominant species contributed more than 90% to the total biomass, while no loss of oil production was observed, the oil yield in the mixed being even higher than in the unialgal culture (3.15 vs. 2.28 mg). The outcomes of the induced competition suggest the use of Dunaliella as a competitive oil-producer species and especially support the potential of the experimental approach to be used for preliminary screening to drive species selection for open mass cultures.

Giulia Savarese, Maria Teresa Ingino
Psychology (PSYCH) , 2018, DOI: 10.4236/psych.2018.914164
Abstract: The data collected from disabled university students who participated in a mindfulness workshop in Italy are presented. The workshop activities are also described. These were aimed at reducing stress and improving coping skills, the sense of self and social relationships. This is the first experience of a mindfulness course with university students with varying types of disability. The initial results were positive in creating the following within the participants: a less emotional interpretation of the world; a greater acceptance of their own difficulties; reduced stress; and, at the same time, implementation of various coping methods and improved self-esteem and social interaction.
The Names of Numbers. Linguistic Considerations
Alberto Manco
Studii de Stiinta si Cultura , 2012,
Abstract: The learning of more prevalent systems of numbering usually goes on for tens: for a child, counting up to ten is the first and most important moment of sharing a “standard” numeral piece of knowledge. But that same child lives in a world in which eggs and pastries are counted in dozens, time is measured in sixtieths and their submultiples and an indeterminable number of linguistic expressions refer us to numeral universes that are inferior or different to those based on tens. This article will put forward some considerations on what is decidedly a broad and complex issue that transcends the lexical dimension.
