Peripheral vascular responses to acute administration of natural progesterone were studied in 12 postmenopausal women (mean +/- SD age 50.3 +/- 4.8 years) with no evidence of cardiovascular disease. According to a randomized, double-blind protocol, all subjects were given natural progesterone as a vaginal cream, able to produce a rapid peak and decay of plasma hormone concentrations, or matched placebo, with crossover after a 1-week washout period. Forearm blood flow and peak flow after ischemic stress (ml/100 ml/min), local vascular resistance (mm Hg/ml/100 ml/min), venous volume (ml/100 ml), and venous compliance (ml/100 ml/mm Hg) were measured by strain-gauge venous occlusion plethysmography at baseline and after progesterone or placebo administration. Plasma norepinephrine concentrations were determined by high-performance liquid chromatography with electrochemical detection. Progesterone sharply decreased forearm blood flow (p <0.01) through an increase in local vascular resistance (p <0.01). Measures of venous function remained unchanged. Although the hormone increased circulating norepinephrine concentrations (p <0.05), there were no significant changes in mean arterial pressure or heart rate. Furthermore, progesterone reduced the local vasodilator capacity, shown by a decrease in forearm delta flow (difference between peak flow and basal flow, p <0.05). Compared with the well-known effect of estrogen, progesterone exerted an opposite action on peripheral vascular responsiveness. Peripheral circulatory changes may be attributed to a direct activity of progesterone on the arterial wall and may in part reflect a modulation of the hormone on peripheral sympathetic tone. Consideration must be given to the hypothesis that the addition of progestin may attenuate the beneficial effects of unopposed estrogen replacement therapy in postmenopausal women.

Physical activity is known to convey protection against several cancers. However, results on the risk of lymphoma overall and its subtypes have been inconsistent. The aim of this study was to investigate occupational and recreational physical activity in relation to risk of lymphoma subtypes adjusting for established occupational risk factors. We applied standardized tools to assess energy expenditure at work and in recreational physical activities to the questionnaire information on lifetime work and exercise history in 1117 lymphoma cases, including Hodgkin lymphoma, and B-cell (including chronic lymphocytic leukemia, and multiple myeloma) and T-cell non-Hodgkin's lymphoma (NHL) subtypes, and 1207 controls who took part in the multicentre European EpiLymph case-control study. We calculated the risk of lymphoma (all subtypes), B-cell NHL and its most represented subtypes, and Hodgkin's lymphoma (all subtypes) associated with weekly average Metabolic Equivalent of Task (MET-hours/week) and cumulative MET-hours of lifetime recreational, occupational, and total physical activity, with unconditional logistic regression and polytomous regression analysis adjusting by age, centre, sex, education, body mass index, history of farm work and solvent use. We observed an inverse association of occupational, and total physical activity with risk of lymphoma (all subtypes), and B-cell non-Hodgkin's lymphoma among women, and an upward trend in risk of Hodgkin's lymphoma with recreational and total physical activity among men, for which we cannot exclude chance or bias. Our results suggest no effect of overall physical activity on risk of lymphoma and its subtypes., Competing Interests: Declaration of Competing Interest Mariagrazia Zucca reports was provided by EpiLymph paper on physical activity.

Background: The evidence linking the use of household pesticides and the risk of lymphoma is scanty., Methods: We explored the hypothesis in a population-based case-control study on lymphoma conducted in Sardinia, Italy, in 1998-2004, including 325 cases and 465 population controls and data on lifetime frequency, seasonality, and years of use of household insecticides and potential confounders. We calculated the risk of lymphoma (all subtypes) and its major subtypes associated with using household insecticides in three time windows (up to 1978, from 1979-2001, and 2002 onwards) with unconditional logistic regression adjusting by age, sex, education, and occupational exposure to pesticides., Results: Household insecticides did not increase risk of lymphoma (all subtypes), Hodgkin's lymphoma, B-cell lymphoma, and the major B-cell lymphoma subtypes. The risk of multiple myeloma (MM) but not the other subtypes showed a non-significant upward trend ( p = 0.203) with increasing quartiles of days of use in the time window when propoxur was the most popular household insecticide., Conclusions: Our results suggest no association between the household use of insecticides and the risk of lymphoma. Further studies are warranted to confirm or discard an association between MM risk and the use of propoxur.

Background: Previous research has shown an excess risk of COVID-19 among several occupations, but data on public transport workers are scarce. To investigate the occupational risk posed by contact with the public, we followed up the incidence of COVID-19 in a cohort of public transport workers., Methods: We identified the incident cases of COVID-19 between 1 September 2020 - 6 May 2021 in a cohort of 2,052 employees of a public transport agency in Sardinia, Italy. The diagnosis of COVID-19 was based on a positive molecular test. To calculate the expected events, we applied the age- and gender-specific incidence rates of the regional population in the same time period to the correspondent strata of the study cohort. We estimated the relative risk (RR) of COVID-19 as the ratio between the observed and the expected events and its 95% confidence interval (95% C.I.) among the total cohort and in two sub-cohorts: bus drivers, and the rest of the personnel (administrative staff, train and metro drivers, workers in the mechanical shop, and in the railroad maintenance, and security)., Results: Bus drivers run an elevated risk of COVID-19 (RR = 1.4, 95% C.I. 1.07 - 1.79). There was no excess risk among the sub-cohort including the rest of the personnel., Conclusions: Our study suggests an excess risk of COVID-19 among bus drivers even in a relatively low incidence area, which could imply inadequacy of the preventive measures in place. Further, larger size studies with detailed information on personal and lifestyle characteristics are warranted.

Background: Night shift work can disrupt circadian rhythm and cause chronic sleep deprivation, which might increase the risk of lymphoma through immunosuppression and oxidative stress., Material and Methods: We investigated the association between night shift work and risk of lymphoma subtypes in 867 incident cases and 774 controls, who participated in a multicentre Italian study between 2011 and 2017. Based on questionnaire information, occupational experts assessed the lifetime probability of night shift work, the total number of night shifts and years of night shift work among study participants. OR and 95% CI for lymphoma and its major subtypes associated with night shift work was calculated with logistic regression, adjusting by age, gender, education, study area, marital status and family history of haemolymphatic cancer., Results: Ever working night shifts was associated with an increase in the risk of chronic lymphocytic leukaemia (CLL) (OR 1.9, 95% CI 1.14 to 3.32), which was highest after a 15-34 years latency. However, there was not a linear increase in risk by probability of exposure, years of night shift work, nor lifetime number of night shifts whether under rotating or permanent work schedules. Risk of lymphoma overall, B cell lymphoma (BCL), its major subtypes other than CLL, and other less prevalent BCL subtypes combined did not show an association., Conclusions: We found conflicting evidence of an association between night shift work and the risk of CLL. We did not observe an association with other lymphoma subtypes., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2022. No commercial re-use.

A few reports have described increasing trends and spatial distribution of multiple myeloma (MM). We used a validated database including the 1606 cases of MM diagnosed in Sardinia in 1974-2003 to explore its time trend, and we applied Bayesian methods to plot MM probability by administrative unit on the regional map. Over the 30 years of observation, the MM standardized incidence rate (standard world population, all ages) was 2.17 × 10 -5 (95% CI 2.01-2.34), 2.29 (95% CI 2.06-2.52) among men, and 2.06 (95% CI 1.83-2.28) among women. MM incidence increased by 3.3%/year in 1974-2003, in both males and females, particularly among the elderly and in the high incidence areas. Areas at risk tended to cluster in the north-eastern part of the region. A higher proportion of elderly in the resident population, but not socioeconomic factors, nor livestock farming, was associated with higher incidence rates. The steep upward time trend and the spatial clustering of MM suggest interactions between genetic and environmental determinants that might be more efficiently investigated in the areas at risk., (© 2022.

Background: Determining the proportion of susceptible workers can represent a first step to the biological risk assessment related to measles, mumps, rubella and varicella exposure. This study aimed to assess the immunity against measles, mumps, rubella and varicella viruses in a cohort of female school workers., Methods: A cross-sectional seroepidemiological study in a sample of 263 school workers undergoing routine annual workplace health surveillance program was conducted. As part of the health surveillance program, serum samples were collected and tested for measles, mumps, rubella and varicella IgG antibodies., Results: Overall seropositivity was 90.5%, 85.2%, 94.7% and 97.3% for measles, mumps, rubella and varicella, respectively. In relation to mumps occupation-specific seropositivity, a statistically significant difference was observed, showing the lowest prevalence of protected individuals in other occupation groups. Moreover, in relation to rubella, school workers born in Centre Italy had the lowest seropositivity of protective antibodies and the difference between groups was statistically significant. Measles and rubella seropositivity showed a significant decrease after 2015., Conclusions: This study showed a relevant proportion of school workers susceptible to the aforementioned diseases. These results highlighted the need for proper health surveillance and immunological controls in school workers, especially for females, and provided useful insights to policymakers to select effective strategies aimed at containing the risk of vaccine-preventable diseases at schools.

Background: The International Agency for Research on Cancer (IARC) recently classified glyphosate, the most used herbicide worldwide, as a probable human carcinogen. We inquired into the association between occupational exposure to glyphosate and risk of lymphoma subtypes in a multicenter case-control study conducted in Italy., Methods: The Italian Gene-Environment Interactions in Lymphoma Etiology (ItGxE) study took place in 2011-17 in six Italian centres. Overall, 867 incident lymphoma cases and 774 controls participated in the study. Based on detailed questionnaire information, occupational experts classified duration, confidence, frequency, and intensity of exposure to glyphosate for each study subject. Using unconditional regression analysis, we modelled risk of major lymphoma subtypes associated with exposure to glyphosate adjusted by age, gender, education, and study centre., Results: Very few study subjects (2.2%) were classified as ever exposed to glyphosate. Risk of follicular lymphoma (FL) was elevated 7-fold in subjects classified as ever exposed to glyphosate with medium-high confidence, 4.5-fold in association with medium-high cumulative exposure level, 12-fold with medium-high exposure intensity, and 6-fold with exposure for 10 days or more per year. Significant upward trends were detected with all the exposure metrics, but duration. The overall p-value for an upward trend with four independent metrics was 1.88 × 10 - 4 . There was no association with risk of lymphoma (any subtype), Non Hodgkin Lymphoma, B-cell lymphoma, or the major lymphoma subtypes other than FL., Conclusions: Our findings provide limited support to the IARC decision to classify glyphosate as Group 2A human carcinogen.

Background: The main anthropic sources of exposure to airborne benzene include vehicular traffic, cigarette smoke, and industrial emissions., Methods: To detect early genotoxic effects of environmental exposure to benzene, we monitored environmental, personal, and indoor airborne benzene in children living in an urban area and an area near a petrochemical plant. We also used urinary benzene and S-phenylmercapturic acid (S-PMA) as biomarkers of benzene exposure and urinary 8-hydroxydeoxyguanosine (8-OHdG) as a biomarker of early genotoxic effects., Results: Although always below the European Union limit of 5 μg/m 3 , airborne benzene levels were more elevated in the indoor, outdoor, and personal samples from the industrial surroundings compared to the urban area ( p = 0.026, p = 0.005, and p = 0.001, respectively). Children living in the surroundings of the petrochemical plant had urinary benzene values significantly higher than those from the urban area in both the morning and evening samples ( p = 0.01 and p = 0.02, respectively). Results of multiple regression modelling showed that age was a significant predictor of 8-OHdG excretion, independent of the sampling hour. Moreover, at the low exposure level experienced by the children participating in this study, neither personal or indoor airborne benzene level, nor personal monitoring data, affected 8-OHdG excretion., Conclusions: Our results suggest the importance of biological monitoring of low-level environmental exposure and its relation to risk of genotoxic effects among children.

Objectives This study aimed to estimate the risk of lymphoma and its major subtypes in relation to occupational exposure to specific organic dusts. Methods We explored the association in 1853 cases and 1997 controls who participated in the EpiLymph case-control study, conducted in six European countries in 1998-2004. Based on expert assessment of lifetime occupational exposures, we calculated the risk of the major lymphoma subtypes associated with exposure to six specific organic dusts, namely, flour, hardwood, softwood, natural textile, synthetic textile, and leather, and two generic (any types) groups: wood and textile dusts. Risk was predicted with unconditional regression modeling, adjusted by age, gender, study center, and education. Results We observed a 2.1-fold increase in risk of follicular lymphoma associated with ever exposure to leather dust [95% confidence interval (CI) 1.01-4.20]. After excluding subjects who ever worked in a farm or had ever been exposed to solvents, risk of B-cell lymphoma was elevated in relation to ever exposure to leather dust [odd ratio (OR) 2.2, 95% CI 1.00-4.78], but it was not supported by increasing trends with the exposure metrics. Risk of Hodgkin lymphoma was elevated (OR 2.0, 95% CI 0.95-4.30) for exposure to textile dust, with consistent upward trends by cumulative exposure and three independent exposure metrics combined (P=0.023, and P=0.0068, respectively). Conclusions Future, larger studies might provide further insights into the nature of the association we observed between exposure to textile dust and risk of Hodgkin lymphoma.

Objectives: To explore the time trend and geographical distribution of childhood leukaemia incidence over the territory of the Italian region of Sardinia., Setting: All hospitals departments, diagnostic centres and social security agencies in Sardinia were regularly screened in 1974-2003 to identify, register and review the diagnoses of incident cases of haematological malignancies (HM)., Participants: The whole child population aged 0-14 resident in Sardinia., Primary and Secondary Outcome Measures: Incidence and time trend of childhood HM and childhood acute lymphoblastic leukaemia (ALL) over the study period, and use of Bayesian methods to plot the probability of areas with excess incidence on the regional map., Results: Overall, 675 HM cases, including 378 ALL cases, occurred among children aged 0-14 years resident in Sardinia in 1974-2003, with an incidence rate of 6.97×10 -5 (95% CI 6.47 to 7.51) and 3.85×10 -5 (95% CI 3.48 to 4.26), respectively. Incidence of HM and ALL showed an upward trend along the study period especially among females. Three communes out of the 356 existing in 1974, namely Ittiri, Villa San Pietro and Carbonia, stand out as areas with excess incidence of HM and ALL in particular and another, Carloforte, for ALL only., Conclusions: Our results might serve as convincing arguments for extending the coverage of routine cancer registration over the whole Sardinian population, while prompting further research on the genetic and environmental determinants in the areas at risk., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2020.

Background: Biomechanical overload due to patients' manual handling represents a relevant contributor to chronic low back pain (LBP). Fear of movement (also known as kinesiophobia) and catastrophising may influence the development of chronic complaints and lower performances also in working environments, despite these issues are poorly investigated., Aim: The aim of this study is twofold: 1) to evaluate the levels of kinesiophobia and catastrophizing in a sample of health personnel with chronic LBP and employed in activities specifically requiring patients' manual handling; 2) to appraise the influence of these factors on disability., Design: Cross-sectional observational study., Setting: Four Italian hospitals., Population: Sixty-four healthcare workers suffering from nonspecific low back pain, exposed to the spinal risk of biomechanical overload due to patients' manual handling., Methods: We assessed kinesiophobia, catastrophizing and disability by means of validated questionnaires (the Tampa Scale of Kinesiophobia [TSK], the Pain Catastrophizing Scale [PCS], and the Oswestry Disability Index [ODI], respectively). Values of central tendency and dispersion of the variable of interest were calculated, along with the association among variables through multiple linear regression analysis., Results: The results showed presence of kinesiophobia (TSK=34.0; IQR=28.2-42.09), catastrophizing (PCS=20.5; IQR=10.2-29.0) and disability (ODI=28.8; IQR=13.5-40.0) in the population enrolled. Disability was significantly predicted by kinesiophobia and catastrophizing (R2=0.529 P=0.00003)., Conclusions: Kinesiophobia and catastrophizing are present in health workers with chronic LBP involved in patients' manual handling and are linked to disability. Further investigations in this field are recommended to investigate a role for cognitive-behavioral strategies aimed at managing catastrophizing and kinesiophobia to increase working abilities., Clinical Rehabilitation Impact: The assessment of catastrophizing and kinesiophobia is crucial in health workers engaged with patients' manual handling and suffering from chronic LBP.

Background: Evidence linking risk of lymphoma and B-cell lymphoma subtypes to ionizing radiation is inconclusive, particularly at low exposure levels., Methods: We investigated risk of lymphoma (all subtypes), B-cell lymphomas, and its major subtypes, associated with low-level occupational exposure to ionizing radiation, in 2346 lymphoma cases and 2463 controls, who participated in the multicenter EpiLymph case-control study. We developed a job-exposure matrix to estimate exposure to ionizing radiation, distinguishing between internal and external radiation, and we applied it to the lifetime occupational history of study subjects, We calculated the Odds Ratio (OR) and its 95% confidence interval (95% CI) for lymphoma (all subtypes combined), B-cell lymphoma, and its major subtypes using unconditional, polytomous logistic regression adjusting for age, gender, and education., Results: We did not observe an association between exposure metrics of external and internal radiation and risk of lymphoma (all subtypes), nor with B-cell lymphoma, or its major subtypes, at the levels regularly experienced in occupational settings. An elevated risk of diffuse large B cell lymphoma was observed among the most likely exposed study subjects with relatively higher exposure intensity, which would be worth further investigation., Conclusions: Further investigation is warranted on risk of B cell lymphoma subtypes associated with low-level occupational exposure to external ionizing radiation, and to clarify whether lymphoma should be included among the cancer outcomes related to ionizing radiation.

Breast cancer is one of the most common diseases worldwide, mainly affecting the female gender. Considering the increase of breast cancer incidence and the decrease of mortality due to news diagnostic and therapeutic tools, the return to work issue after treatment is going to be very common in the next years. Occupational physicians therefore need to face the return to work and the fitness for work of workers previously diagnosed with breast cancer with a sufficient cultural and technical background. In addition to individual characteristics preceding the diagnosis, clinical outcome, lifestyles and occupational variables are the most impactful factors on return to work that need to be taken into account. The aim of this work is to analyze these factors and discuss the central role of occupational physicians in the decision-making process of returning to work in breast cancer survivors., Competing Interests: The authors declare no conflict of interest.

Background : In spite of the reduced exposure level, and its ban in numerous countries, compensation claims for asbestos-related diseases are far from decreasing. Methods : We used retrospective exposure assessment techniques to explore respiratory function and a computerized tomography (CT) scan in relation to past asbestos exposure in 115 male workers retired from an acrylic and polyester fiber plant. Based, on detailed information on exposure circumstances, we reconstructed a cumulative exposure estimate for each patient. Results : Time-weighted average exposure in our study population was 0.24 fibers/ml (95% confidence inteval (CI) 0.19-0.29), and the average cumulative exposure was 4.51 fibers/mL-years (95% CI 3.95-5.07). Exposure was elevated among maintenance workers, compared to other jobs ( p = 0.00001). Respiratory function parameters did not vary in relation to the exposure estimates, nor to CT scan results. Risk of interstitial fibrosis showed a significant upward trend (Wald test for trend = 2.62, p = 0.009) with cumulative exposure to asbestos; risk associated with 5.26 fibers/mL-years or more, was 8-fold (95% CI 1.18-54.5). Conclusions : Our results suggest that a CT scan can detect pleuro-parenchymal lung alterations at asbestos exposure levels lower than previously thought, in absence of respiratory impairment. Further studies are required to validate our techniques of retrospective assessment of asbestos exposure.

Objectives: Arsenic is a toxic metal ubiquitous in the environment and in daily life items. Long-term arsenic exposure is associated with severe adverse health effects involving various target organs. It would be useful to investigate the existence of metabolic alterations associated with lifestyle and/or with the environment. For this purpose, we studied the correlation between urinary arsenic levels and urinary proton nuclear magnetic resonance spectroscopy ( 1 H NMR) metabolomics profiles in a non-occupationally nor environmentally arsenic exposed general population. Methods: Urine samples were collected from 86 healthy subjects. Total and non-alimentary urinary arsenic (U-naAs) levels, namely the sum of arsenite, arsenate, monomethylarsonate and dimethylarsinate, were measured and 1 H NMR analysis was performed. Orthogonal Projection to Latent Structures was applied to explore the correlation between the metabolomics profiles and U-naAs levels. Results: Despite the extremely low U-naAs levels (mean value = 6.13 ± 3.17 µg/g creatinine) of our studied population a urinary metabolomics profile related to arsenic was identified. Conclusion: The identified profile could represent a fingerprint of early arsenic biological effect and could be used in further studies as an indicator of susceptibility, also in subjects exposed to a low arsenic dose, with implications in occupational health, toxicology, and public health.

: Background: Work-related stress is a potential cardiovascular risk factor, but the underlying mechanism is not fully explained. The autonomic nervous system control of cardiac function might play a specific role; therefore, monitoring the QT interval in the electrocardiogram can highlight an autonomic imbalance induced by occupational stressors. The aim of our study was to explore the QT interval parameters as early indicators of imbalance of the autonomic cardiac function in relation to work-related stress., Methods: During 2015-2016 annual workplace health surveillance, we measured work-related stress in 484 workers of a logistic support company using the Health and Safety Executive (HSE) tool. We assessed the frequency-corrected QT (QTc) interval and the QT index (QTi) on the electrocardiogram of each participant, and collected demographic and clinical data. We compared the QTc values by the four Karasek's categories (active/passive jobs, low/high strain job), and by job support (present/lacking), and conducted multivariate analysis to adjust for possible confounders., Results: The results of the multivariate regression analysis showed that QTc was prolonged among workers operating at a specific site where stress level was found to be elevated. Regular physical activity showed a beneficial effect against QTc prolongation. We did not observe an effect on QTc length by the cross-combined Karasek's categories of job control, job demand, and job support., Conclusions: Our study suggests subclinical effects of conditions associated with work-related stress on the autonomic regulation of cardiac function. Further research is warranted to elucidate the combined effect of work organization and lifestyle factors on autonomic cardiac function., Competing Interests: The authors declare no conflict of interest.

The institution of specific Occupational Health and Safety (OHS) training programs open to international trainees from developing countries in some European, American and Asian universities is now a well-established reality. Courses and seminars that focus particularly on this subject, widely varying in approach and duration, have been held for years at these universities; these academic institutions have combined their potential to attract students from developing countries with the scheduling of interesting lectures and training activities, depending on the availability of funds sufficient to cover travel and lodging costs. Interdisciplinarity is the key to the entire program and is its main strength, as the trainees have the opportunity to condense the technical notions and methodological aspects of different disciplines (occupational health, industrial hygiene, safety management, ergonomics) in one course. We firmly believe that these programs are a precious instrument for the training of occupational health professionals from low-income countries, as they are able to address their choices correctly, hopefully achieving the goal of reducing the human costs of development., Competing Interests: The authors have no competing interests to declare., (© 2018 The Author(s).

Purpose: The purpose of this study was to investigate patients' and caregivers' health needs for a re-orientation program based on principles of health promotion in an Oncology Department from an Italian University Hospital., Method: A Cross-sectional design with qualitative and quantitative approaches was used. Participants included cancer patients and their caregivers. Information about disease concerns were collected using a survey form. Information about healthy lifestyle was obtained using motivational interviews. Information about perceived quality of oncology services was collected by a self-administered questionnaire., Results: A total of 403 information requests were collected about patients' disease, 203 motivational interviews were carried out, and 219 questionnaires were collected. Overall, the results showed that patients and caregivers have healthy lifestyles even if meat consumption was high. Weak points were: poor physical space organization in the Service, long waiting times, and limited access to healthcare providers for patients., Conclusions: This study revealed the need for an approach based on health-promotion principles, with a particular focus on patient wellbeing and quality of life. The study increases awareness about the influence that an environment has on patient health, thus suggesting that changes in culture, attitude, and health services re-organization are crucial to meet total needs of the individual as a whole process., (Copyright © 2017 Elsevier Ltd.

(1) Background: The assessment of airborne particulate matter (PM) and ultrafine particles (UFPs) in battlefield scenarios is a topic of particular concern; (2) Methods: Size distribution, concentration, and chemical composition of UFPs during operative military training activities (target drone launches, ammunition blasting, and inert bomb impact) were investigated using an electric low-pressure impactor (ELPI+) and a scanning electron microscope (SEM), equipped with energy-dispersive spectroscopy (EDS); (3) Results: The median of UFPs, measured for all sampling periods and at variable distance from sources, was between 1.02 × 10³ and 3.75 × 10³ particles/cm³ for drone launches, between 3.32 × 10³ and 15.4 × 10³ particles/cm³ for the ammunition blasting and from 7.9 × 10³ to 1.3 × 10⁴ particles/cm³ for inert launches. Maximum peak concentrations, during emitting sources starting, were 75.5 × 10⁶ and 17.9 × 10⁶ particles/cm³, respectively. Particles from the drone launches were predominantly composed of silicon (Si), iron (Fe) and calcium (Ca), and those from the blasting campaigns by magnesium (Mg), sulphur (S), aluminum (Al), iron (Fe), barium (Ba) and silicon (Si); (4) Conclusions: The investigated sources produced UFPs with median values lower than other anthropogenic sources, and with a similar chemical composition., Competing Interests: Upon mandate from the Manager of the University Hospital of Cagliari, Doctor Marcello Campagna is the Occupational Physician of the Quirra Interforce Firing Range. Nanoparticle emission during military operational activity is currently the object of a lawsuit.

Objectives: (1)H NMR-metabolomic approach was used to investigate QTc interval correlation with plasma metabolic profiles in shiftworkers., Methods: Socio-demographic data, electrocardiographic QTc interval and plasma metabolic profiles from 32 male shiftworkers, were correlated by multivariate regression analysis., Results: We found a positive correlation between QTc interval values, body mass index, glycemia and lactate level and a negative correlation between QTc interval and both pyroglutamate and 3-hydroxybutyrate plasma level., Conclusions: Our analysis provides evidence of the association between clinical, metabolic profiles and QTc interval values. This could be used to identify markers of early effects and/or susceptibility in shiftworkers.

Background and Aim: Health care workers are exposed to several job stressors that can adversely affect their wellbeing. Workplace incivility is a growing organizational concern with the potential to create workplaces harmful to individuals' wellbeing and increase occupational health risks. Based on the Job Demands-Resources (JD-R) model, the purpose of the present study was to investigate the role of two resources (organizational empowerment and job control) on individuals' well-being (emotional exhaustion) and attitude at work (unit affective commitment)., Materials and Methods: A total of 210 hospital workers completed a self-administered questionnaire that was used to measure organizational empowerment, workplace incivility, job control, exhaustion, and affective commitment. Data were collected in 2014. Data were examined via linear regression analyses., Results: The results showed that workplace incivility was positively related to emotional exhaustion and negatively related to affective commitment. Workplace empowerment was positively related to affective commitment and negatively related to emotional exhaustion. Furthermore, the positive relationship between workplace empowerment and affective commitment was significantly moderated by job control., Conclusion: Our results found support for the JD-R model. Specifically, results showed the buffering effect of job control in the relationship between empowerment and affective commitment. Our findings may concretely contribute to the stress literature and offer additional suggestions to promote healthy workplaces.

Objectives: to compare the patterns of a 17 beta-estradiol (E(2)) gel containing 0.6 mg/g (1.5 mg E(2) per day, Gelestra); with the transdermal delivery system (Estraderm TTS 50) applied every 3 days over a 14-day period to women in spontaneous or surgical menopause., Methods: a single centre, open, randomised, parallel-group study was conducted. A total number of 33 postmenopausal women were enrolled. In 23 of them the menopause occurred spontaneously, while 10 women were bilaterally ovariectomized. Randomly, the subjects were treated with Estraderm TTS 50 (no. 8) or with Gelestra (no. 14). The pharmacokinetic study of the drugs was performed at the seventh, ninth and 14th day in Gelestra treated women and at the first, third and second day in Estraderm TTS 50 treated women. In fact, the seventh, ninth and 14th day of percutaneous treatment corresponds to the first, third and second day of application of the transdermal system application. Blood samples were taken by each subject at baseline and 1, 2, 3, 4, 8, 12 and 24 h after the gel or transdermal system application. In almost all samples the level of E(2) and estrone (E(1)) were evaluated. Statistical analysis was performed by comparing the two groups of treatment. The following parameters were assessed: mean E(2) and E(1) concentrations, E(2) peak serum concentration within interval from 0 to 72 h (C(max)), E(2) trough concentration within interval from 0 to 72 h (C(min)), area under the E(2) time concentration curve in the interval from 0 to 72 h (AUC((0-72))), the average E(2) concentration during the measurement interval, calculated by dividing AUC((0-72)) by 72 h (C(av)), E(1)/E(2) ratio, and percentage fluctuation (%Fluct) which is equal to 100 (C(max)-C(min)/C(max))., Results: there was no significant difference in E(2) C(av) between the two treatments. However, significant differences in favour to the gel on the first day (first h) and on third day (72nd h) and in favour to the patch at the second day (48th h) were detected. C(max), E(1)/E(2) ratio and AUC((0-72)) were not statistically different, while a significantly higher C(min) for the gel was observed. Furthermore, the 90% confidence interval for AUC((0-72)) ratio (0.83-1.10) was within the commonly applied bioequivalence acceptance range (0.80-1.25). The %Fluct was significantly lower for Gelestra than for Estraderm TTS 50., Conclusions: although the mean E(2) and E(1)concentrations, C(max), E(1)/E(2) ratio and the AUC((0-72)) did not differ between the two E(2) treatments, the Gelestra treatment showed a lower day-to-day variation over the three day application, than the Estraderm TTS 50.

We studied 16 postmenopausal women with mild to moderate hypertension according to a randomized, double-blind protocol. They received patches of transdermal estradiol-17beta rated to deliver 100 mg/day of substance or matched placebo. A 24-hour ambulatory blood pressure (BP) monitoring was performed at baseline and after drug administrations. Our data show that estradiol-17beta exerts beneficial effects, both in lowering elevated BP levels and in maintaining a uniform BP control over 24 hours. Estrogen replacement therapy could be considered when significant changes in BP occur during the postmenopausal period.
