No Correlation between Blood Benzene Levels and Luteinizing Hormone Plasma Values in Outdoor Workers.

Objective: The purpose of the study is to evaluate whether low-dose exposure to benzene, an environmental pollutant to which male and female traffic policemen are daily exposed to could cause alterations in plasma luteinizing hormone (LH) levels.

Methods: From an initial sample of 1594 workers, we only selected 95 workers of whom study we knew the values of late-shift benzene and LH hormone. All subjects underwent biological monitoring (final blood benzene evaluation) and luteinizing hormone dosing.

Work related stress and blood glucose levels.

Aim: The aim of the study is to evaluate work-related subjective stress in a group of workers on a major Italian company in the field of healthcare through the administration of a valid "questionnaire-tool indicator" (HSE Indicator Tool), and to analyze any correlation between stress levels taken from questionnaire scores and blood glucose values.

Material And Methods: We studied a final sample consisting of 241 subjects with different tasks. The HSE questionnaire - made up of 35 items (divided into 7 organizational dimensions) with 5 possible answers - has been distributed to all the subjects in occasion of the health surveillance examinations provided by law.

Work-related stress in healthcare workers.

Background: In the assessment of work-related stress it is crucial to find the factors that generate and increase it in order to identify categories of individuals at risk, to plan interventions for prevention, elimination or reduction of risk. The aim of the study is to assess the subjective stress in 68 workers of a large Italian company dealing with human health, through the use of a questionnaire-indicating tool, elaborated by the Italian National Institute for insurance against accidents at work (INAIL) and developed by the Health and Safety Executive (HSE).

Methods: We studied a final sample of 68 individuals (34 drivers/rescuers and 34 video display unit (VDU) operators).

[Arterial pressure in workers exposed to urban stressors].

The aim of this study is to evaluate whether occupational exposure to urban stressors could cause alterations of systolic and diastolic blood pressure in "outdoor" workers. The research was conducted on a sample of 101 municipal policemen. The sample was divided in 2 groups according to length of service: group A (length of service between 1 and 15 years) and group B (length of service > 15 years).

[Prolonged exposure to urban pollutants and arterial blood pressure: a whole evaluation of our researches].

Aim: A significant relationship between exposure to cadmium and PAHs from urban air pollution and blood pressure has already been found. The aim of the study is to evaluate if other urban pollutants maintain a similar relationship in outdoor workers.

Materials And Methods: 349 subjects of both sexes were enrolled in the study; we evaluated values of environmental and biological monitoring of respirable dust, arsenic, lead, benzene, toluene, xylene and we measured blood pressure (BP) in upright and in supine position; to analyze data we used multiple linear regression.
