RESUMEN
OBJECTIVE: The aim of this study is to evaluate whether the exposure to a low dose of nickel could determinate a variation in levels of progesterone in outdoor workers. MATERIALS AND METHODS: Two hundred sixty one subjects were divided by sex, task, age, seniority, and cigarette smoking habit. For each workers was evaluated the dose of blood progesterone and urinary nickel.The statistical analysis was performed. RESULTS: The Pearson correlation showed a statistically significant correlation between urinary nickel levels and progesterone. The multiple linear regression showed a significant correlation between progesterone and urinary nickel in the total sample and in the subgroups of smokers and workers with tasks of traffic direction. CONCLUSIONS: The results of our study suggest that occupational exposure to low doses of nickel present in urban pollution may influence to progesterone levels in outdoor workers.

The study aimed to compare the distortion-product otoacoustic emissions (DPOAEs) with the pure-tone audiometry and to analyze the changes in participants exposed to noise. The results show a prevalence of participants with impaired DPOAEs higher than the prevalence of participants with impaired audiometries in the total sample, in men, and in outdoor workers and a prevalence of impaired DPOAEs and of impaired audiometries in men higher than in women and in outdoor workers higher than in indoor workers. The comparison of mean values between outdoor and indoor workers shows a significant difference only on some frequencies, in the DP-gram. The results suggest a higher effectiveness of DPOAEs compared with the pure-tone audiometry in identifying the presence of any damage in individuals exposed to noise at an early stage.

INTRODUCTION: The aim of our study is to evaluate the changes in systolic and diastolic blood pressure in two occupational categories: outdoor workers (traffic policemen and environment technicians) and indoor workers. MATERIALS AND METHODS: The study was conducted comparing the results obtained from three samples of male workers: 175 outdoor traffic policemen, 175 outdoor environment technicians and 175 indoor workers. The outdoor and indoor groups were made comparable by age, length of service, body mass index, alcohol consumption, smoking status. RESULTS: The mean values of systolic and diastolic blood pressure were found higher in traffic policemen and technicians than in indoor workers, as well as higher values of systolic blood pressure in traffic policemen than in technicians. CONCLUSIONS: The results suggest that outdoor working affects the blood pressure, contributing to an increased cardiovascular risk.

BACKGROUND: Few studies in the literature have examined the effects of benzene on blood cells. AIM: The aim of this study was to evaluate the possible correlation between the blood benzene levels and the blood cell counts. MATERIALS AND METHODS: From a population of 2658 workers, we studied a group of 215 subjects. Each worker underwent blood sampling for the assessment of the blood benzene levels and the blood cell counts. The Mann-Whitney U test for two-mode variables and the Kruskal-Wallis test for more-than-two-mode variables were performed on all subjects. We estimated the Pearson correlation index between the variables in the total sample and the subgroups divided according to sex, the smoking habit, and job. After the main confounding factors were evaluated, multiple linear regression was performed on both the total sample and the subgroups. RESULTS: A significant inverse correlation was found among the blood benzene levels and the white blood cells, lymphocytes, and neutrophils in traffic policemen, motorcyclists, and other outdoor workers. We did not find any significant correlation with any other parameters of blood cell count. DISCUSSION AND CONCLUSIONS: Our results, which must be considered preliminary, indicate that increased blood benzene levels in outdoor workers lead to decreased counts of white blood cells, neutrophils, and lymphocytes, because of possible immune effects. These are worth investigating in the future by specific immune tests.

OBJECTIVES: The aim of this study is to evaluate whether exposure to low concentrations of cadmium (Cd) can have effects on the thyroid hormone level of outdoor workers exposed to urban pollutants. METHODS: The study was conducted on a final sample of 277 individuals (184 males and 93 females). The environmental monitoring of Cd was evaluated through the use of portable dosimeters, while the biological monitoring was achieved through the assessment of urinary Cd and thyroid hormones. The total sample was divided according to sex and task. The Pearson's correlation coefficient among the variables was calculated after subdivision on the basis of sex and task. The multiple linear regression was performed to take into account the major confounding factors. RESULTS: Statistical tests showed a negative correlation between urinary Cd levels and free triiodothyronine and free thyroxine and a positive correlation between urinary Cd and thyroid-stimulating hormone levels. CONCLUSIONS: Our early results seem to point out that occupational exposure to low concentrations of Cd present in urban air affects the thyroid hormone levels in exposed workers.

Nickel (Ni) and Ni compounds are widely present in the urban air. The purpose of this study is to estimate exposure of individuals to Ni and the correlation between this exposure and the values of blood counts in outdoor workers. This study focused on a sample of 101 outdoor workers (55 male and 46 female; 65 nonsmokers and 36 smokers), all employed in the municipal police in a large Italian city. The personal levels of exposure to Ni were assessed through (a) environmental monitoring of Ni present in the urban air obtained from individual samples and (b) biological monitoring of urinary and blood Ni. The blood count parameters were obtained from the hemochromocytometric tests. Pearson correlation coefficients (r) were calculated to assess the association between the blood and urinary Ni and the complete blood count. Multiple linear regression models were used to examine the associations between the complete blood count and the independent variables (age, gender, years of work for current tasks, cigarette smoking habit (current and never smoker), values of airborne Ni, and blood and urinary Ni). Multiple linear regression analysis performed on the total group of 101 subjects confirms the association among the red blood cells count, the hematocrit, and the urinary Ni (R(2) = 0.520, p = 0.025 and R(2) = 0.530, p = 0.030). These results should lead to further studies on the effects of Ni in working populations exposed to urban pollutants. The possibility that the associations found in our study may be partially explained by other urban pollutants (such as benzene, toluene, and other heavy metals) not taken into consideration in this study cannot be ruled out.

The aim of this study is to determine whether in workers exposed to urban pollution the risk of developing overweight and obesity is higher in workers exposed to urban pollution compared to a control group. The study was conducted on 150 volunteers, 75 workers exposed to urban pollution (50 women and 25 men) and 75 indoor workers (50 women and 25 men). Once measured the weight and height and calculated body mass index (BMI) for each worker, the research was based on the comparison, between the two groups, of the mean values of the measurements and of the frequency of workers with BMI index higher than the cut-off of normality. The only statistically significant difference found was for the mean value of weight in women, which was higher among outdoor workers compared to indoor workers. The mean values of BMI and the frequency of workers with BMI higher than normal was higher among outdoor workers compared to indoor workers in both sexes, but not statistically significant. The data suggest that outdoor workers may be subject to an additional risk of developing obesity as a result of exposure to urban air pollution (which, like obesity, is a source of oxidative stress). So, our preliminary study encourages to continue this line of research by implementing the sample and considering all the confounding factors. Furthermore, the results highlight the necessity to take account of gender differences in the context of health surveillance of workers.

The present study shows detailed information about the reliability and validity of the psychosocial risk scale included in the Stress Questionnaire (SQ) developed by our research group. The primary purpose of this work is to test the factor structure of the psychosocial risk scale through a first-order confirmatory factor analysis (CFA) using a large pooled dataset obtained from a population of 2026 employees of 15 Italian medium-large companies. Data were collected by a team of researchers who examined demographic variables, work-related stress, workplace bullying, mental health and other constructs. In addition to these substantive issues, the survey was designed to better understand response bias. After the evaluation of the results we conclude that the psychosocial risk scale reported a satisfactory reliability and validity. In addition, it allowed a careful measurement of work related stress, considering both leader's and follower's perspectives.

The aim of our study is to estimate if the occupational exposure to formaldehyde can cause alterations of leukocytes plasma values in health care workers employed in a big hospital compared to a control group. We studied employees in operating rooms and laboratories of Pathological Anatomy, Molecular Biology, Molecular Neurobiology, Parasitology and Experimental Oncology (exposed to formaldehyde) and employees of the Department of Internal Medicine (not exposed). The sample studied was composed of 86 workers exposed to formaldehyde and 86 workers not exposed. All subjects underwent a clinical-anamnaestic examination and for all subjects were measured the following values: total white blood cells, lymphocytes, monocytes and granulocytes (eosinophils, basophils, neutrophils). Statistical analysis of data was based on calculation of the mean, standard deviation and the distribution into classes according to the nature of each variable. Differences were considered significant when p was < 0.05. The mean and the distribution of values of the white blood cells, lymphocytes, monocytes and eosinophils were significantly higher in male subjects exposed to formaldehyde compared to not-exposed. Not significant differences were found in female subjects exposed compared to not exposed. The results underline the importance of a careful risk assessment of workers exposed to formaldehyde and the use of appropriate preventive measures. The health care trained and informed about the risks he is exposed to should observe good standards of behavior and, where it is not possible to use alternative materials, the indoor concentrations of formaldehyde should never exceed occupational limit values.

The aim of this study was to evaluate the usefulness and specificity of urinary 1-hydroxypyrene (1-OHPu) as a biomarker of the exposure from urban pollution to polycyclic aromatic hydrocarbons (PAHs) among outdoor workers in a meta-analysis. Our meta-analysis was performed according to standard methods, and the results show that the concentrations of 1-OHPu tend to be higher in exposed workers than in unexposed workers (if we exclude two highly heterogeneous articles), in exposed non-smokers than in unexposed non-smokers and in exposed than in unexposed workers who were carriers of the CYP1A1 genotype and in those with the glutathione-S-transferase M1 (-)genotype. These genotypes enhance the effect of exposure, particularly in non-smokers. Smoking reduces the differences between exposed and unexposed subjects. In conclusion, our results suggest that the use of the 1-OHPu biomarker appears to be reliable for studying occupational exposure to PAHs from urban pollution, as long as environmental and behavioural factors are considered.

The aim of this study is to estimate whether the occupational exposure to low dose anesthetic gases could cause alterations of blood parameters in health care workers. 119 exposed subjects and 184 not exposed controls were included in the study. Each worker underwent the complete blood count test (CBC), proteinaemia, leukocyte count, serum lipids, liver and kidney blood markers. The liver blood markers show statistically significant differences in health care workers compared with controls (p<0.05), a statistically significant decrease in neutrophils and an increase of lymphocytes in health care workers compared with controls (p<0.05). The prevalence of values outside the range for GPT, GGT, total bilirubin, lymphocytes and neutrophils was statistically significant in health care workers compared with controls (p<0.05). The results suggest that occupational exposure to low dose anesthetic gases could influence some haematochemical hepatic and hematopoietic parameters in exposed health care workers.

PURPOSE: To evaluate whether the exposure to arsenic (As) causes alterations of liver enzymes in two groups of outdoor workers. METHODS: Total urinary As and the levels of AST/GOT, ALT/GPT, and GGT were measured on 80 traffic policemen and 50 police drivers. Personal air samples were obtained for assessing the exposure to As on a subgroup of 20 traffic policemen and 20 police drivers. RESULTS: Mean values of personal exposure to As, urinary As, AST/GOT, and ALT/GPT were significantly higher in traffic policemen than in the police drivers. Multiple linear regression models showed associations between urinary As and airborne As, ALT/GPT and the job variables, and BMI and urinary As. CONCLUSIONS: These findings contribute toward the evaluation of the hepatic effects of exposure to As in the urban workers.

The aim of our study is to verify whether the exposure to low Ni doses in urban air may have some effects on the prolactin values of outdoor workers exposed to urban pollutants. 334 workers have been included in the study and divided on the basis of gender, job, age, length of service and smoking habits. Each worker underwent urinary Ni and prolactin sampling. The t-test for independent samples, the Mann-Whitney U test for two mode variables (gender, smoking habit), the univariate ANOVA test and the Kruskal Wallis test for the variables in more than two modes (age, length of service and job duties) were performed on the total sample. Pearson's correlation coefficient (p two-tailed) among the parameters was evaluated both in the total sample and after the stratification by gender, smoking habit and job. Multiple linear regression was performed after taking account of the major confounding factors on the total sample and on the subcategories. The statistical tests showed a significant correlation between urinary Ni and prolactin both in the total sample and in the subcategories. We believe that the occupational exposure to low doses of Ni present in urban pollution may influence the prolactin values in exposed workers.

PURPOSE: The aim of this study is to evaluate whether perceived stress in the workplace can be a risk factor able to change the blood counts in a group of male and female outdoor workers of the Municipal Police. The study examines possible relations among the levels of stress, as inferred from the scores of the questionnaire, blood counts and voluptuary habits. METHODS: We evaluated a final sample of 486 subjects (345 males and 141 females). During the medical examination was performed for each subject: a) the administration of the questionnaire to assess the perception of work-related stress, b) the collection of clinical.anamnestic information related to the consumption of coffee, chocolate, alchool and smoking habit, c) the taking of a venous blood sample. All workers included in the study were divided into three groups on the basis of the scores of the questionnaire. RESULTS: About 61% of workers showed a moderate or severe stress condition, with a statistically significant prevalence (p<0.05) of female workers and younger subjects. The increase of perceived stress coincided with a significant decrease (p <0.05) of the mean levels of white blood cells and with a significant increase (p <0.05) of the consumption of coffee, chocolate and smoking habit. There was no statistically significant differences for alcohol consumption. CONCLUSIONS: The results show that the stress induces a reduction of the white blood cells, an increase of coffee and chocolate consumption and of smoking.

OBJECTIVES: In the general population, cadmium seems to be responsible for hypertension, atherosclerosis and an increase in acute coronary events. Therefore, the purpose of this meta-analysis was to analyze controlled studies conducted on cadmium and arterial pressure in occupationally-exposed workers. MATERIALS AND METHODS: After analyzing all the relevant articles found in the literature, 6 publications were selected. RESULTS: A higher prevalence of hypertension and higher values of systolic and diastolic blood pressure were recorded in the exposed subjects. CONCLUSIONS: Cadmium in occupationally-exposed individuals appears to induce an increase in systolic and diastolic blood pressure and an increase in the prevalence of hypertension.

The technological and industrial progress together with the intensification of vehicular traffic and the adoption of new social habits are the cause of an increasing noise pollution with possible negative effects on the auditory system. This study aims to assess the noise exposure levels and the effects on the hearing threshold in outdoor and indoor male workers of a big Italian city. The study was carried out on 357 outdoor male workers, exposed to urban noise and on a control group of 357 unexposed indoor workers. Noise levels were measured in 30 outdoor and indoor areas. The subjects underwent tonal liminal audiometry in order to determine the value of their hearing threshold. During their working activity, outdoor and indoor workers are exposed to different noise levels LEX<80 dB(A). At mid-low frequencies (250-2000 Hz), the results show significant differences in the average values of hearing threshold between the two groups in both ears and for all age classes; there are no significant differences between the two groups at higher frequencies. The outdoor noise levels measured are not usually ototoxic and the hearing loss at mid-low frequencies is not characteristic of the exposure to industrial noise. For these reasons the Authors hypothesize that the results may be due to the combined effect of the exposure to noise and to ototoxic air pollutants. The impairment of speech frequencies is disabling and involves the risk of missed forensic recognition.

The aim of the study was to assess the relationship between occupational exposure to airborne lead (Pb) and alterations in peripheral blood counts in workers of the Municipal Police assigned to different types of outdoor tasks. Then, 337 both male and female subjects were enrolled and divided on the basis of sex, cigarette smoking habit and kind of task. Exposure to airborne Pb, dosage of total blood Pb and peripheral blood count were carried out. A significant positive correlation was detected between the values of total blood Pb and values of plasma reticulocytes (%RET) both in the total sample and for all the classes of the subdivision except for police drivers. Some statistically significant correlations were present but discontinuous for other variables of peripheral blood counts. Results suggest that occupational exposure to low doses of airborne Pb is able to influence lines of the hematopoietic system in exposed workers, with special reference to %RET.

INTRODUCTION: In health care the contact with body fluids, such as saliva or blood is frequent. The aim of our study was to analyze whether the exposure to biological risks in health care, in particular exposure to HBV and HCV, could cause alterations of some liver parameters. MATERIALS AND METHODS: Our study analyzes of 254 health care workers of a big hospital in Rome. The subjects exposed to biological risks were divided into two groups, one exposed to a high biological risk and the other one exposed to a low biological risk, according to individual duties and/or the departments where they carry out their work. We checked the markers for hepatitis B and C in order to highlight a possible infection, the possible vaccine coverage and the control of the antibody titer by previous infection. We measured the values of transaminases, GGT, alkaline phosphatase, total bilirubin and fractional proteinaemia total and electrophoresis. RESULTS: In health care workers exposed to high risk the average values of transaminases, total protein, alkaline phosphatase, gamma GT, total bilirubin were not significant compared to the some values formed in workers exposed to low risk (p > 0.05). Subjects positive for hepatitis B and C were 4% in the group of workers exposed to high risk (class 1) while in the group of workers exposed to low risk (class 2) the percentage of exposed individuals was 0.01% for the hepatitis B and 2.6% for hepatitis C. DISCUSSION AND CONCLUSIONS: We found a small numbers of positive cases of hepatitis B and C in people exposed to biological agents. We did not find alterations of the average values of transaminases, total protein, alkaline phosphatase, gamma GT, total bilirubin and albumin in positive cases, so that we can say that the proper use of personal protective equipment, training and information of workers and the observance of universal precautions are effective in protecting workers.

The new D. Lgs. N 81, 2008 Article 28 paragraph 1 sanctions that the risk assessment must involve all the possible risks to safety and health of workers, including the work-related stress factors. Stressors at work may vary as to: quantity of work assigned, whether excessive or inadequate; lack of recognition or reward for good job performance; degree of responsibility; precariousness of work; emotional pressures exerted on workers; violence and harassment of psychological nature, poor balance between work and private life. The need man has to understand the causes of his psycho-physical and social disease are old. Only the words we use when dealing with the topic has changed over the time: once it was Alienation now it is Burn-out. The concept of alienation, which has been very important over the time, has many different aspects and has had countless interpretations (which have followed one another), the psycho-analytical, the sociological analysis and the Marxist one, Burnout is actually a syndrome characterized by three interrelated dimensions: exhaustion, cynicism and inefficacy. Therefore it is important to prevent, eliminate or reduce problems related to occupational stress. Among preventive measures, the Europe Agreement identified in the management and in the communication the information necessary to define the goals of the company and the role each employee has. Moreover information and formation are considered the necessary elements to increase awareness and understanding of the problem, its potential causes and possible ways of approading it. Our research group, has developed targeted questionnaires, biological indicators and medical instrumental examinations the occupational doctors can make use of to assess these issues.

The aim of this study was to assess whether exposure to urban pollution in outdoor workers, may alter plasma cortisol concentrations also in relation to the effect of smoking and drinking habits. The research was carried out on 498 outdoor police workers, divided into three groups; Group A: traffic policemen (TP), Group B: drivers (D), Group C: Other duties (OD). To evaluate separately the effect of using alcohol and smoking, each group was divided into three subgroups: (1) non-smokers and non-drinkers, (2) smokers and non-drinkers, (3) non-smokers and drinkers. Our results show cortisol mean values were significantly higher in the TP group compared to the D and OD groups without significant differences between the last two groups. The results suggest that exposure to pollutants associated with urban psychosocial stress may play a more important role on plasma cortisol levels than smoking and alcohol.
