Background: Most personal exposures to UV radiations occur from outdoor activities and several studies detected a significant association between skin cancer and outdoor occupation.
Objective: The aim of the study was to ascertain the prevalence of photoaging signs in a population of Italian farmers and in a population of indoor workers taking account of confounding factors.
Methods: 169 farmers and 198 indoor workers were classified for skin phototype and for skin photoaging, moreover 13 variables were taken into account. Marginal permutation tests were adopted for statistical analysis.
Results: Farmers were significantly older than the indoor workers. In workers occupationally exposed to UV photoaging increased with increasing age and years of occupational exposure to sunlight The distribution of skin phototype did not show significant differences in the two populations, while farmer showed a higher degree of photoaging than indoor workers.
Conclusions: Even if farmers were older than the in door workers it seems that outdoor work produces a higher degree of photoaging.

Dental operations inherently involve a high risk of airborne cross-infection among medical staff and patients due to the exposure of respiratory secretions, which contain pathogenic microorganisms and typically spread in the form of aerosols. In order to contribute to the understanding of aerosol dynamics during dental operation and efficiently mitigate their dispersion and deposition through appropriate ventilation, 3D numerical simulations and full-scale experimental measurements were performed in this study. The indoor airflow distribution and dynamic aerosol behaviors observed under three optimized ventilation schemes (Scenario I-III) were compared with those observed under the current ventilation system.

Biophilic workplace design has been proposed as an effective strategy to increase employee well-being in open-plan offices. To expand our understanding of why and for whom indoor nature exposure increases well-being, the aim of this study was to evaluate vigor as a mediator and to examine whether nature relatedness is a direct antecedent of nature exposure or a moderator of the relationship between exposure to nature and vigor. Based on longitudinal data obtained from a two-wave panel design with white-collar workers in open-plan offices (Study 1, n = 345; Study 2, n = 291), using a rival model strategy and two dependent variables, i.

Objective: assessment of probable exposure levels from radon and NORM in workplaces within the context of justi fying radiation protection plans in an existing exposure situation.
Materials And Methods: Materials regarding the assessment of naturally occurring radioactive material (NORM) con tent in tailing from mining and processing industries in Ukraine and assessments of contamination levels of industri al sites of oil and gas enterprises were used for estimating the probable range of effective doses (ED) of workers fromNORM at industrial enterprises.

Department of Internal Medicine, Faculty of Medicine, University of Manitoba, Winnipeg, MB, Canada.
Background: This study characterized the risk of new-onset asthma among workers in Manitoba, Canada.
Methods: Accepted time loss claims from the Workers' Compensation Board of Manitoba from 2006 to 2019, containing workers' occupations and industries, were linked with administrative health data from 1996 to 2020. After restricting the cohort to the first claim per person in an occupation and applying age and coverage exclusions, the cohort comprised 142,588 person-occupation combinations.
