Association between Ideal Cardiovascular Health and aortic stiffness in Italian adolescents. The MACISTE study.

BACKGROUND AND AIMS: Ideal Cardiovascular Health (ICH), defined as optimal levels of cardiovascular (CV) health factors and behaviors, has been reported to be very low in adults and children, with consequent several negative health outcomes and higher CV risk. The present study investigated the burden of ICH among Italian adolescents and its association with carotid-femoral pulse wave velocity (cf-PWV). METHODS AND RESULTS: 387 healthy adolescents (mean age 17.1 ± 1.4 years) attending the "G. Donatelli" High School in Terni, Italy, were evaluated. ICH was assessed through clinical evaluation, laboratory measures and interviewer-administered questionnaires. Cf-PWV was measured by arterial tonometry (SphygmoCor). For each ICH metric, a score of 2 was assigned for ideal levels, 1 for intermediate, and 0 for poor. All subjects showed at least one ICH metric, whereas none showed all ICH 7 metrics. The average number of ICH metrics was 4.3 ± 1.1. The highest rates were observed for fasting blood glucose (98%), whereas an ideal healthy diet was achieved only by 8% of subjects. The Cf-PWV was inversely and linearly associated with the sum of ICH metrics (p = 0.03) and the ICH score (p < 0.01). At the multivariate analysis, the association between ICH score and cf-PWV remained significant after adjustment for age, sex, heart rate, mean arterial pressure and other confounders (p = 0.04). CONCLUSION: ICH is relatively uncommon among Italian adolescents and inversely related to cf-PWV. Our results showed a detrimental association between CV unhealthy factors and behaviors with increased aortic stiffness, which starts developing at an early stage of the lifespan.

Trichophyton verrucosum infection in cattle farms of Umbria (Central Italy) and transmission to humans.

Trichophyton verrucosum is the most common ringworm agent in cattle. Epidemiology of cattle dermatophytoses in Central Italy is not clear. Its diffusion among cattle and herdsmen was investigated in 20 Umbrian farms, Central Italy. Hairs and scales were taken from 395 animals and 31 workers. Typical ringworm was present in 71.7% of cattle under 6 months and in 11% of animals over 6 months. T. verrucosum was isolated from 98.9% of symptomatic heads and was the most prevalent dermatophyte in all herds investigated (isolated in 18 of the 20 farms). T. mentagrophytes var. mentagrophytes was found in 16 symptomatic and in eight asymptomatic young animals. Prevalence of asymptomatic carriers of both species was significantly higher in young heads (21.1% vs. 8.1%) and the age below 6 months was the only statistically significant risk factor associated with dermatophytosis. About the workers, all the 14 men with lesions were positive for T. verrucosum; copresence of T. verrucosum and Microsporum gypseum was noticed in one case. Results indicate a high diffusion of T. verrucosum among both animals and humans in Umbrian farms and confirm the dermatophyte infection as a public health problem. Periodic epidemiological surveys, treatment of sick livestock and workers, cleaning/sanitisation of herds and vaccination programmes may be useful in controlling the infection.
