Exposure to Endocrine Disruptors (Di(2-Ethylhexyl)phthalate (DEHP) and Bisphenol A (BPA)) in Women from Different Residing Areas in Italy: Data from the LIFE PERSUADED Project.

Phthalates and bisphenol A (BPA) are plasticizers used in many industrial products that can act as endocrine disruptors and lead to metabolic diseases. During the LIFE PERSUADED project, we measured the urinary concentrations of BPA and Di(2-ethylhexyl)phthalate (DEHP) metabolites in 900 Italian women representative of the Italian female adult population (living in the north, centre, and south of Italy in both rural and urban areas). The whole cohort was exposed to DEHP and BPA with measurable levels above limit of detection in more than 99% and 95% of the samples, respectively. The exposure patterns differed for the two chemicals in the three macro-areas with the highest urinary levels for DEHP in south compared to central and northern Italy and for BPA in northern compared to central and southern Italy. BPA levels were higher in women living in urban areas, whereas no difference between areas was observed for DEHP. The estimated daily intake of BPA was 0.11 µg/kg per day, about 36-fold below the current temporary tolerable daily intake of 4 µg/kg per day established by the EFSA in 2015. The analysis of cumulative exposure showed a positive correlation between DEHP and BPA. Further, the reduction of exposure to DEHP and BPA, through specific legislative measures, is necessary to limit the harmfulness of these substances.

Italian Children Exposure to Bisphenol A: Biomonitoring Data from the LIFE PERSUADED Project.

A human biomonitoring (HBM) study on bisphenol A (BPA) in Italian children and adolescents was performed within the LIFE PERSUADED project, considering the residing areas, sex and age. The median urinary BPA level was 7.02 µg/L, with children living in the South of Italy or in urban areas having higher levels than those residing in the North or in rural areas. Children aged 4-6 years had higher BPA levels than those aged 7-10 and 11-14 years, but no differences were detected between sexes. The exposure in Italian children was higher compared to children from other countries, but lower than the HBM guidance value (135 µg/L). The estimated daily intake was 0.17 µg/kg body weight (bw) per day, about 24-fold below the temporary Tolerable Daily Intake of 4 µg/kg bw per day established by the European Food Safety Authority. However, this threshold was exceeded in 1.44% of the enrolled children, raising concern about the overall exposure of Italian young population.

Biomonitoring of Bis(2-ethylhexyl)phthalate (DEHP) in Italian children and adolescents: Data from LIFE PERSUADED project.

The Bis(2-ethylhexyl)phthalate (DEHP), a widespread plasticizer, is considered an endocrine disrupting chemical with main toxicological effects on reproductive and metabolic systems. Human biomonitoring (HBM) studies are promoted to evaluate the background exposure levels. In the frame of LIFE PERSUADED project, the HBM study measured DEHP main metabolites (mono-(2-ethylhexyl) phthalate, MEHP; 2-ethyl-5-hydroxy-hexylphthalate, MEHHP; 2-ethyl-5-oxo-hexylphthalate, MEOHP) in Italian children and adolescent (4-14 years old) according to geographical macro-areas and areas, age and sex. Children from the South and the Centre of Italy showed higher median levels of DEHP, as a sum of its metabolites (48.14 and 47.80 µg/L), than those from the North (39.47 µg/L; p = 0.0090 and 0.0004, respectively). Considering the total population, boys are more exposed than girls (only as urinary volume), and children aged 4-6 years have higher median levels than those 7-10 and 11-14 years old. The derived reference values (RV95) for DEHP in children is 168 µg/L. The relative metabolic rates of DEHP, the background levels and, thus, the RV95, vary with the geographical area, age and sex, indicating that all these parameters should be considered in the risk assessment.

[The UNESCO brand in the prosecco hills: opportunity or new health risk?] / Il marchio UNESCO sulle colline del prosecco: opportunità o nuovo rischio per la salute?

The historical hill-site zone of Prosecco's wine production was recognised as a UNESCO World Heritage Site. This area is part of the province of Treviso, an area where in recent years many lands have been occupied by the viticulture to produce this type of wine, due to a growing demand of prosecco, especially on international markets. Currently viticulture occupies 31% of the total agricultural area of the province. This is determining an important alteration of the landscape of the area, with serious loss of biodiversity. Even more, this intensive cultivation requires the use of many pesticides (in 2018, 4,622 tons were sold, equivalent to more than 36 kg per hectare of arable land), that are harmful to the health of the population. They can cause acute effects by inhalation or contact during the treatment of the vines, and chronic effects for the continuous intake of small doses through contaminated waters. To safeguard the environment and health, two actions are needed: to reduce the use of pesticides by promoting organic production; to restore biodiversity by promoting other crops besides the vineyards. Our hope is that belonging to the UNESCO heritage world list favours these actions.

Management of cryptorchidism: a survey of clinical practice in Italy.

BACKGROUND: An evidence-based Consensus on the treatment of undescended testis (UT) was recently published, recommending to perform orchidopexy between 6 and 12 months of age, or upon diagnosis and to avoid the use of hormones. In Italy, current practices on UT management are little known. Our aim was to describe the current management of UT in a cohort of Italian children in comparison with the Consensus guidelines. As management of retractile testis (RT) differs, RT cases were described separately. METHODS: Ours is a retrospective, multicenter descriptive study. An online questionnaire was filled in by 140 Italian Family Paediatricians (FP) from Associazione Culturale Pediatri (ACP), a national professional association of FP. The questionnaire requested information on all children with cryptorchidism born between 1/01/2004 and 1/01/2006. Data on 169 children were obtained. Analyses were descriptive. RESULTS: Overall 24% of children were diagnosed with RT, 76% with UT. Among the latter, cryptorchidism resolved spontaneously in 10% of cases at a mean age of 21.6 months. Overall 70% of UT cases underwent orchidopexy at a mean age of 22.8 months (SD 10.8, range 1.2-56.4), 13% of whom before 1 year. The intervention was performed by a paediatric surgeon in 90% of cases, with a success rate of 91%. Orchidopexy was the first line treatment in 82% of cases, while preceded by hormonal treatment in the remaining 18%. Hormonal treatment was used as first line therapy in 23% of UT cases with a reported success rate of 25%. Overall, 13 children did not undergo any intervention (mean age at last follow up 39.6 months). We analyzed the data from the 5 Italian Regions with the largest number of children enrolled and found a statistically significant regional difference in the use of hormonal therapy, and in the use of and age at orchidopexy. CONCLUSIONS: Our study showed an important delay in orchidopexy. A quarter of children with cryptorchidism was treated with hormonal therapy. In line with the Consensus guidelines, surgery was carried out by a paediatric surgeon in the majority of cases, with a high success rate.
