This study indicates a higher circulation of HEV in HIV-infected patients, whereas a low prevalence of HEV antibodies in the general Italian population was shown. Chronic hepatitis with HEV alone was absent, while it was present in subjects with HIV-HEV, co-infected with hepatitis B virus (HBV) and/or hepatitis C virus (HCV).

Background: Screenings for infectious diseases in asymptomatic immigrants currently takes place when receiving new arrivals. Aims: We describe the frequency of infections in a cohort of newly arrived asymptomatic immigrants in Southern Italy. Methods: We studied a cohort of 238 Sub-Saharan African and Asian men hosted at a reception centre (CARA) in Foggia between January and December 2015. The tuberculin skin test for diagnosis of latent tuberculosis infection (LTBI) and serology/virology testing for HBV, HCV, HIV were performed. Results: From this cohort, 205 individuals agreed to be tested for serological/virological markers only, while 82 agreed to be tested for LTBI only; 49 people agreed to have both tests. Among those tested for virological markers, 23/205 (11.2%) were HBsAg positive; 12/23 (52.2%) individuals had chronic active hepatitis; 77/205 (37.6%) individuals had only anti-HBc positivity. HCV infection was present in 8/205 (3.9%) individuals, and chronic HCV infection, was diagnosed in only two people. Only 2/205 (1.0%) individuals presented with anti-HIV and HIV-RNA positivity. We found LTBI in 29.6% of TB-tested individuals. Conclusions: Asymptomatic immigrants are at increased risk for some infections, mainly HBV and tuberculosis.

The increase in international competition and the constant research for improving reliability and reducing costs have spurred the applications of the system monitoring to power plant; the monitoring function are extremely useful for a plant management purposes and fault diagnosis. In particular Failure Detection and Isolation strategies monitor system operations for degradation and, if detected, classify the failure source. In this paper, after a brief description of the different approaches at the FDI problem, we consider the model-based methods (analytical redundancy) and in particular the parameter identification of a system on the basis of observed inputloutput data. Some algorithms have been developed inside an European project (TOPand the monitoring system realized by Elsag Bailey Energy & Industry Division can now add to the standard functions these tools for the fault detection routines. An illustrative example of an industrial application is given.
