ABSTRACT
The Erice 56 Charter titled "Impact of the environment on the health: from theory to practice" was unanimously approved at the end of the 56th course of the "International School of Epidemiology and Preventive Medicine G. D'Alessandro" held from 3rd to November 7, 2019 in Erice - Sicily (Italy) and promoted by the Study Group of "Environment and Health" of the Italian Society of Hygiene, Preventive Medicine and Public Health. The course, that included lectures, open discussions and guided working groups, was aimed to provide a general training on epidemiological and toxicological aspects of the environmental health impact, to be used by public health professionals for risk assessment, without forgetting the risk communications. At the end of the course 12 key points were agreed among teachers and students: they underlined the need of specific training and research, in the perspective of "One Health" and "Global Health", also facing emerging scientific and methodological issues and focusing on communication towards stakeholders. This Discussion highlight the need to improve knowledge of Health and Environment topic in all sectors of health and environmental prevention and management.

The mutagenic activity of airborne particulate matter collected in Pisa, a small nonindustrial town located in Italy, has been monitored over 1 year using the Ames Salmonella Test. Airborne particulate was collected on fibreglass filters using a Hi-Vol sampler and extracted by sonication and Soxhlet acetone extraction in sequence. TA 98 and TA 100 salmonella strains gave positive results with the great majority of samples. The mutagenicity trend fits with a harmonic regression with a peak during December/January and inversely correlates with the temperature. No correlations were observed with other meteorological conditions such as wind, cloud, rainfall, atmospheric pressure, and humidity. The ratio between mutagenicity/microgram of particulate matter with S9 and that without S9 remains more or less constant regardless of seasonal fluctuations, suggesting that during cold months quantitative increases of mutagens onto particulate matter have probably occurred. The comparison of air mutagenicity in different sites suggests that motor vehicle exhaust fumes are the major source of air pollution. Finally, because of high-traffic volume, air mutagenicity at street level is comparable to that observed in several metropolitan areas all over the world.

Hypertriglyceridemia has frequently been found both in subjects with AIDS and in asymptomatic HIV-positive ones. In order to evaluate the importance of hyperlipemia as an index of the clinical evolution of HIV infection, the levels of triglycerides, total cholesterol and CD4 lymphocytes were determined over a period of 2 years in 8 haemophiliacs with AIDS, 13 asymptomatic HIV-positive and 45 HIV-negative haemophiliacs attending the Operative Unit of Coagulation Disorders of the University of Pisa. The mean concentration of triglycerides and incidence of hypertriglyceridemia were significantly higher in haemophiliacs with AIDS, compared with HIV-negative subjects (p<0.0001), while the triglycerides values of asymptomatic HIV-positives fell between those of the other groups. Cholesterol levels were lower in HIV-positive haemophiliacs and in those with AIDS compared with HIV-negatives. No correlation was found between triglyceride levels and those of CD4 lymphocytes.
