Retrospective analysis of the Italian exit strategy from COVID-19 lockdown.

After the national lockdown imposed on March 11, 2020, the Italian government has gradually resumed the suspended economic and social activities since May 4, while maintaining the closure of schools until September 14. We use a model of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) transmission to estimate the health impact of different exit strategies. The strategy adopted in Italy kept the reproduction number Rt at values close to one until the end of September, with marginal regional differences. Based on the estimated postlockdown transmissibility, reopening of workplaces in selected industrial activities might have had a minor impact on the transmissibility. Reopening educational levels in May up to secondary schools might have influenced SARS-CoV-2 transmissibility only marginally; however, including high schools might have resulted in a marked increase of the disease burden. Earlier reopening would have resulted in disproportionately higher hospitalization incidence. Given community contacts in September, we project a large second wave associated with school reopening in the fall.

Occupational Physicians' Management of Workers With Multiple Sclerosis in Italy: Results From a Survey.

BACKGROUND: This study, conducted on a sample of Italian occupational physicians (OPs), aimed to gather data regarding professional activity and their needs in managing workers with multiple sclerosis. METHODS: A convenience sample of OPs recruited by e-mail invitation to the list of Italian Society of Occupational Medicine members was considered. A total of 220 OPs participated between July and October 2022. An ad hoc questionnaire was developed based on previous survey experiences. It investigated, among others, the characteristics of OP respondents, the evaluation of fitness for work issues, and the OP training and updating needs on multiple sclerosis and work. RESULTS: Ninety-one percent of OPs had to assess the fitness for work of workers with multiple sclerosis during their activity. Sixty-four percent experienced particular difficulties in issuing a fitness for work judgment. Regarding the level of knowledge on multiple sclerosis, 54% judged it sufficient. The "Assessment of fitness for work for the specific task" and the "Role of the OPs in identifying reasonable accommodations" were the most interesting training topics regarding MS management in work contexts chosen by the respondents. CONCLUSIONS: The interest in the work inclusion and job retention of people with disability, particularly the aspects linked to the Identification and implementation of reasonable accommodations, will require integration with the occupational safety and health protection system and will undoubtedly impact the OP's activities.

New global indicator for workers' health: mortality rate from diseases attributable to selected occupational risk factors.

Through sustainable development goals 3 and 8 and other policies, countries have committed to protect and promote workers' health by reducing the work-related burden of disease. To monitor progress on these commitments, indicators that capture the work-related burden of disease should be available for monitoring workers' health and sustainable development. The World Health Organization and the International Labour Organization estimate that only 363 283 (19%) of 1 879 890 work-related deaths globally in 2016 were due to injuries, whereas 1 516 607 (81%) deaths were due to diseases. Most monitoring systems focusing on workers' health or sustainable development, such as the global indicator framework for the sustainable development goals, include an indicator on the burden of occupational injuries. Few such systems, however, have an indicator on the burden of work-related diseases. To address this gap, we present a new global indicator: mortality rate from diseases attributable to selected occupational risk factors, by disease, risk factor, sex and age group. We outline the policy rationale of the indicator, describe its data sources and methods of calculation, and report and analyse the official indicator for 183 countries. We also provide examples of the use of the indicator in national workers' health monitoring systems and highlight the indicator's strengths and limitations. We conclude that integrating the new indicator into monitoring systems will provide more comprehensive and accurate surveillance of workers' health, and allow harmonization across global, regional and national monitoring systems. Inequalities in workers' health can be analysed and the evidence base can be improved towards more effective policy and systems on workers' health.

Par le biais des objectifs de développement durable 3 et 8 ainsi que d'autres mesures, plusieurs pays se sont engagés à protéger et promouvoir la santé des travailleurs en réduisant l'impact des maladies liées au travail. Mais pour évaluer leurs progrès en la matière, il convient de mettre en place des indicateurs estimant l'impact des maladies liées au travail afin de placer le développement durable et la santé des travailleurs sous surveillance. D'après l'Organisation mondiale de la Santé et l'Organisation internationale du Travail, seulement 363 283 (19%) des 1 879 890 décès liés au travail dans le monde en 2016 découlaient de blessures, tandis que 1 516 607 (81%) d'entre eux étaient causés par des maladies. La plupart des systèmes de surveillance qui s'intéressent à la santé des travailleurs ou au développement durable, comme le cadre mondial d'indicateurs pour les objectifs de développement durable, comportent un indicateur relatif à l'impact des accidents de travail. Cependant, rares sont ceux qui possèdent un indicateur concernant l'impact des maladies professionnelles. Pour combler cette lacune, nous dévoilons un nouvel indicateur mondial: le taux de mortalité dû aux maladies attribuables à certains facteurs de risque professionnels classé par maladie, facteur de risque, sexe et catégorie d'âge. Nous exposons le motif politique de l'indicateur, décrivons l'origine des données et les méthodes de calcul, et communiquons et analysons l'indicateur officiel pour 183 pays. Nous fournissons également des exemples de la façon dont l'indicateur peut être utilisé dans des systèmes nationaux de surveillance de la santé des travailleurs et soulignons ses forces et faiblesses. Nous concluons en affirmant que l'intégration de ce nouvel indicateur dans les systèmes de surveillance offrira un suivi plus complet et précis de la santé des travailleurs et ouvrira la voie à une harmonisation des systèmes mondiaux, nationaux et régionaux. Il est possible d'analyser les inégalités en matière de santé des travailleurs et d'en améliorer les bases factuelles afin d'établir des politiques et systèmes plus efficaces dans ce domaine.

A través de los objetivos de desarrollo sostenible 3 y 8 y de otras políticas, los países se han comprometido a proteger y promover la salud de los trabajadores reduciendo la carga de morbilidad relacionada con el trabajo. Para supervisar los avances en el cumplimiento de estos compromisos, debería disponerse de indicadores que reflejen la carga de morbilidad relacionada con el trabajo, a fin de controlar la salud de los trabajadores y el desarrollo sostenible. La Organización Mundial de la Salud y la Organización Internacional del Trabajo estiman que solo 363 283 (19%) de las 1 879 890 muertes relacionadas con el trabajo a nivel mundial en 2016 se debieron a lesiones, mientras que 1 516 607 (81%) muertes se debieron a enfermedades. La mayoría de los sistemas de vigilancia centrados en la salud de los trabajadores o el desarrollo sostenible, como el marco de indicadores mundiales para los objetivos de desarrollo sostenible, incluyen un indicador sobre la carga de las lesiones laborales. No obstante, pocos de estos sistemas cuentan con un indicador sobre la carga de las enfermedades relacionadas con el trabajo. Para subsanar esta carencia, presentamos un nuevo indicador mundial: la tasa de mortalidad por enfermedades atribuibles a factores de riesgo laborales seleccionados, por enfermedad, factor de riesgo, sexo y grupo de edad. Describimos la justificación política del indicador, describimos sus fuentes de datos y métodos de cálculo, e informamos y analizamos el indicador oficial para 183 países. También proporcionamos ejemplos del uso del indicador en los sistemas nacionales de vigilancia de la salud de los trabajadores y destacamos las ventajas y las limitaciones del indicador. Concluimos que la integración del nuevo indicador en los sistemas de vigilancia proporcionará una vigilancia más exhaustiva y precisa de la salud de los trabajadores, y permitirá la armonización entre los sistemas de vigilancia mundiales, regionales y nacionales. Se podrán analizar las desigualdades en la salud de los trabajadores y se podrá mejorar la base de evidencias para lograr políticas y sistemas más eficaces en materia de salud de los trabajadores.

Toxicological evaluation of polycrystalline wools in human lung cells.

Aim: Polycrystalline wools (PCW) are included with Refractory ceramic fibers (RCF) in the alumino-silicates family of High Temperature Insulation Wools (HTIW). IARC includes PCW in the ceramic fibers group and considers them as possible human carcinogens (GROUP 2B). Since PCW toxicity is not yet clear, our aim was to evaluate their toxic and inflammatory effects and to compare them with the known RCF effects.Method: We exposed human bronchial (BEAS-2B) and alveolar (A549) cells to 2-100 µg/mL (2.4 × 103-1.2 × 105 fibers/mL; 2.51 × 103-1.26 × 105 fibers/cm2 of PCW and 7.4 × 103-3.7 × 105 fibers/mL; 7.75 × 103-3.87 × 105 fibers/cm2 of RCF) of the tested fibers to evaluate potential viability reduction, apoptosis, membrane damage, direct/oxidative DNA-damage, cytokine release.Results: In A549, PCW did not induce cytotoxicity and apoptosis but they induced significant dose-dependent DNA-damage, although lower than RCF; only RCF induced oxidative effects. PCW also induced an increase in IL-6 release at 100 µg/mL (1.2 × 105 fibers/mL; 1.26 × 105 fibers/cm2). In BEAS-2B, PCW did not induce cell-viability reduction RCF induced a dose-dependent cell-viability decrease. Both fibers show a dose-dependent increase of apoptosis. In BEAS-2B, PCW also induced dose-dependent DNA-damage, although lower than RCF, and slight oxidative effects similar to RCF. PCW also induced an increase of IL-6 release; RCF induced a decrease of IL-8. Summarizing, PCW induce direct-oxidative DNA-damage although to a lower extent than RCF observed by both mass-based and fiber number-based analysis.Conclusion: For the first time, the study shows the potential toxicity of PCW, usually considered safe, and suggests to perform further in vitro studies, also on other cell types, to confirm these findings.

Changes in work-related stressors before and during the COVID-19 pandemic: differences by gender and parental status.

PURPOSE: The COVID-19 pandemic changed people's working conditions worldwide and research suggests increases in work stressors. However, it is not known to what extent these changes differ by gender or parental status. In the present study, we investigate trends in work stressors and whether these differ by gender and parental status. METHODS: We used cross-sectional time series data of the European Working Conditions Survey of 2015 and Living, Working and COVID-19 survey of spring 2020 to examine trends in work stressors by gender and parental status. Work stressors were working in leisure time, lack of psychological detachment and work-life conflict. We applied three-way multilevel regressions reporting prevalence ratios and reported predicted probabilities and average marginal effects to show trends and differences in changes in work stressors. RESULTS: Our multilevel regression results showed elevated prevalence ratios during the pandemic for working leisure time (PR: 1.43, 95% CI 1.34-1.53), psychological detachment (PR: 1.70, 95% CI 1.45-1.99) and work-life conflict (PR: 1.29, 95% CI 1.17-1.43) compared to before the pandemic. Except for working in leisure time, the increase was more significant among women and mothers. The proportion of work-life conflict in 2020 was 20.7% (95% CI 18.7-22.9) for men and 25.8% (95% CI 24.0-27.6) for women, equalling a difference of 5.1% (p < 0.001). CONCLUSIONS: There is evidence that work stressors increased disproportionately for women and mothers. This needs to be monitored and addressed to prevent widening gender inequalities in the quality of work.

Psychosocial Risks in the Changing World of Work: Moving from the Risk Assessment Culture to the Management of Opportunities.

Increased attention to psychosocial risks and their potential impacts on workers' mental and physical health has flourished due to the changes taking place in the world of work. The changes in the world of work and the recent worldwide events have exacerbated the existing psychosocial risks and brought out new psychosocial risks to be considered for protecting workers' health. This favors the opening up of national and international debate on prioritizing psychosocial risks at work at the policies, strategies, and actions level. This contribution highlights the critical issues to be addressed, the needs to be covered, and the opportunities for better and more effective OSH protection in the workplace. Starting from a definition of psychosocial risks and their potential impacts, we offer an overview of the most recent developments in policies and strategies and the contribution of research in this field over time. A critical reflection on emerging topics, main needs, and challenges for organizations and stakeholders is offered. This time of change poses great concerns but also offers a great opportunity of moving from a culture of assessment to a culture of psychosocial risk management for improving workers' well-being, productivity, and health, where the risk assessment is an important step but not a point of arrival.

Occupational scenarios and exposure assessment to formaldehyde: A systematic review.

The objectives of the systematic review were to: identify the work sectors at risk for exposure to formaldehyde; investigate the procedures applied to assess occupational exposure; evaluate the reported exposure levels among the different settings. An electronic search of Pubmed, Scopus, Web of Science and ToxNet was carried out for collecting all the articles on the investigated issue published from January 1, 2004 to September 30, 2019. Forty-three papers were included in the review, and evidenced a great number of occupational scenarios at risk for formaldehyde exposure. All the included studies collected data on formaldehyde exposure levels by a similar approach: environmental and personal sampling followed by chromatographic analyses. Results ranged from not detectable values until to some mg m-3 of airborne formaldehyde. The riskiest occupational settings for formaldehyde exposure were the gross anatomy and pathology laboratories, the hairdressing salons and some specific productive settings, such as wooden furniture factories, dairy facilities and fish hatcheries. Notice that formaldehyde, a well-known carcinogen, was recovered in air at levels higher than outdoor in almost all the studied scenarios/activities; thus, when formaldehyde cannot be removed or substituted, targeted strategies for exposure elimination or mitigation must be adopted.

[A national survey on occupational safety and health: the role of the health and safety representatives.] / IMPAcT-RLS2: Indagine nazionale sulla salute e la sicurezza sul lavoro: il ruolo dei Rappresentanti dei Lavoratori per la Sicurezza.

SUMMARY: The IMPAcT-RLS2 survey is part of a larger context of INSuLa2 research program; its first edition was conducted in 2014 and targeted to all prevention professionals, investigating occupational health and safety (OSH) protection issues perceived by the various professionals' point of view. The survey addressed to Health and Safety Representatives (HS reps.), focused on three regional contexts, was further implemented in 2016 through the IMPAcT-RLS survey, which involved a sample representative at national level, by company size and economic activity sector consisting of about 2,100 subjects. The survey highlighted the importance of having ever more in-depth information on the role of HS reps. and monitoring their evolution over time. This study arises from the need to create periodic and replicable surveys, aimed at increasing knowledge and awareness of prevention systems and promoting increasingly targeted interventions for improving the protection of OSH.

Occupational impact in COVID-19 pandemic according to one year of compensation claims in Italy.

OBJECTIVES: to evaluate the patterns of occupational COVID-19 cases, based on compensation claims applied to the Italian National Institute for Insurance against Accidents at Work (Inail). DESIGN: descriptive analyses of daily time series of compensation claims applications, geographical distributions, and occupations involved. Multivariate analyses have been performed for identifying significant epidemiological pattern. SETTING AND PARTICIPANTS: compensation claims for COVID-19 injuries received by Inail from March 2020 to February 2021 have been analysed. MAIN OUTCOME MEASURES: daily time series of compensation claims applications in the first year of pandemic and comparatively with population data, patterns of occupations majorly involved in time, territorial clusters. RESULTS: in the observed period, Inail has received 155,684 workers' compensation claims with a first peak (more than 1,000 daily compensation claims) in March 2020 and a second peak (more than 1,500) in November 2020. A time dependent geographical pattern was identified, with the Northern regions formerly affected in the first phase, followed by a diffusion in the Central and Southern regions during the summer period. Health technicians (32% and 42% in male and female, respectively) and physicians (15%and 6%) were the most involved workers. The timing of infection was found to depend by job, with physicians, nurses, and health technicians firstly involved with a spread of about 2 weeks with respect to other jobs. Trend in health workers' vaccination has been found in a clear inverse relationship with the decreasing number of compensation claims, remaining, since February 2021, under one hundred daily cases of occupational COVID-19 compensation claims. CONCLUSIONS: different intensities, timing, and characteristics were found among application claims, which address for different pandemic diffusion paths. Health workers are the firstly and most involved impacted by the pandemic. The use of application claims could be useful and effective in monitoring the occupational component of COVID-19 and his trend in time and space. There is a need to establish an epidemiological surveillance system that includes the assessment of work related risk, supporting the effectiveness of public insurance and welfare system, and to harmonize occupational data collection among countries.

Temporal trend in the compensation claim applications for work-related COVID-19 in Italy.

INTRODUCTION: The SARS-CoV-2 pandemic is an impacting challenge for the occupational medicine and epidemiology. The identification of occupational groups most at risk of exposure is critical in contrasting and preventing the epidemic diffusion. OBJECTIVE: To analyse the compensation claim applications collected by the Italian Workers' Compensation Authority (INAIL) for identifying the occupational patterns and the temporal trend, in comparison with general population data. METHODS: Daily time series of compensation claim applications for COVID-19 injuries in the period March-October 2020, has been analysed, estimating the epidemiological parameters of interest and comparing findings with general population data. RESULTS: In the period March-October 2020, 65,804 compensation claim applications for COVID-19 have been collected by INAIL. The ratio between compensation claims applications and COVID-19 cases in the general population appears decreasing in the period, passing from 20% in the first pandemic period (March-April) to 3-4% in the September-October period. During the summer period, an increase in male and not Italian component and a decrease in mean age, Northern regions, and health care workers contributions to the occupational claims applications have been observed. DISCUSSION: The comparative analyses between occupational and general population data allowed to describe how the so called "second wave" of COVID-19 epidemic in Italy involved the occupational settings less than the other risk factors. There is a need to go towards an -occupational surveillance system for COVID-19 infection, with the aim of monitoring and preventing the occupational risk of infection, supporting insurance system effectiveness and managing vaccination policies.

Implementing Smart Working in Public Administration: a follow up study.

BACKGROUND: Starting from February 2020, in Italy most organizations have had a forced transition to flexible working practice - called "smart working in emergency" - due to the Covid-19 epidemic outbreak. This allowed to continue work activities and services and contributed to contain the risk of infection in different sectors, particularly in the public administration. OBJECTIVES: This follow up study focussed on a panel of 187 workers from the Italian Workers' Compensation Authority taking part to a pilot project "Smart Working in INAIL" from January 2019 to December 2019. The aim was to investigate the effects of work organization on work attitudes, work-life balance and health outcomes before and after the introduction of the smart working. METHODS: The data were collected at two time points through a web-based questionnaire. The first wave aimed to collect information up to one month before the implementation of the smart working. The second wave aimed to collect information about potential changes occurred after one year of smart working. RESULTS: This study showed that high demands, low control and low social support might lead to reduced well-being and less satisfaction with work, and have an effect on work engagement and work-life balance. Particularly, improving social support can moderate the negative impact of high strain on well-being, preventing work-life imbalance and risk of isolation. DISCUSSION: Findings and future perspectives are discussed to support stakeholders in defining policies and practices concerning health and wellbeing at work while preserving productivity, for a successful implementation of smart working in the public administration.

Occupational factors in the COVID-19 pandemic in Italy: compensation claims applications support establishing an occupational surveillance system.

INTRODUCTION: The SARS-CoV-2 pandemic is an impacting challenge for occupational health. Epidemiological surveillance of COVID-19 includes systematic tracking and reporting of the total cases and deaths, but suitable experiences of surveillance systems for identifying the occupational risk factors involved in the COVID-19 pandemic are still missing, despite the interest for occupational safety and health. METHODS: A methodological approach has been implemented in Italy to estimate the occupational risk of infection, classifying each economic sector as at low, medium-low, medium-high and high risk, based on three parameters: exposure probability, proximity index and aggregation factor. Furthermore, during the epidemic emergency, the Italian Workers' Compensation Authority introduced the notation of COVID-19 work-related infection as an occupational injury and collected compensation claims of workers from the entire national territory. RESULTS: According to compensation claims applications, COVID-19 infection in Italy has been acquired at the workplace in a substantial portion of the total cases (19.4%). The distribution of the economic sectors involved is coherent with the activities classified at risk in the lockdown period. The economic sectors mostly involved were human health and social work activities, but occupational compensation claims also include cases in meat and poultry processing plants workers, store clerks, postal workers, pharmacists and cleaning workers. CONCLUSIONS: There is a need to go towards an occupational surveillance system for COVID-19 cases, including an individual anamnestic analysis of the circumstances in which the infection is acquired, for the prevention of occupational infectious risk, supporting insurance system effectiveness and managing vaccination policies.

Occupational asbestos exposure after the ban: a job exposure matrix developed in Italy.

BACKGROUND: Asbestos is a well-known carcinogen for humans. The aim of this study is to develop a tool to estimate occupational asbestos exposure in Italy after the ban using information collected in a national dataset. METHODS: Data were collected from firm registries of workers exposed to asbestos in the period 1996-2016. Descriptive statistics (arithmetic mean, standard deviation, geometric mean and geometric standard deviation) were calculated for the main exposure-related variables (activity sector, occupational group and exposure period). An estimate of workers potentially exposed to asbestos was also performed. RESULTS: A total of 19 704 airborne measurements of asbestos exposure was selected from the national database of occupational exposures in the sectors of asbestos abatement. Overall, a geometric mean of 7.93 f l-1 was found, and chrysotile was the asbestos type that had more exposures (41%). A total of 46 422 workers was estimated to be potentially at asbestos exposure risk. Exposure data were summarized by calendar period, activity sector and occupational group. CONCLUSIONS: The construction of a job exposure matrix for different occupation/industry combinations may allow the assessment of occupational exposure to asbestos in several removal and disposal activities, and the estimate of the risks associated with asbestos-related diseases in epidemiological studies.

Cyto-genotoxic and inflammatory effects of commercial Linde Type A (LTA) nanozeolites on human alveolar epithelial cells.

Nanozeolites (NZs) are increasingly used in several sectors, including catalysts, ion exchange materials or thermal isolators, taking advantage of the major property of NZs to absorb residual water and moisture to preserve the insulation of devices and products, but very few data are available on their toxicity. We investigated the potential cyto-genotoxicity and pro-inflammatory effects of manufactured Linde Type A (LTA)-NZs on human alveolar cells (A549) exposed to 10, 25, 50 and 100 µg/mL. LTA NZs were characterized by dynamic light scattering (DLS). Cell viability, mortality and apoptosis were evaluated by cytofluorimetric assay after 24h exposure. Membrane damage was evaluated by lactate dehydrogenase release and direct and oxidative DNA damage induction by formamide-pyrimidine glycosylase-Comet assay after 4 and 24 h. The induction of pro-inflammatory effects was evaluated in terms of interleukin 6 (IL-6) and IL-8 cytokine release after 24 h by ELISA. We found a slight increase in apoptotic cell percentage at 50 and 100 µg/mL and dead cell percentage at 100 µg/mL after 24 h; slight, but statistically significant, direct DNA damage starting from 25 µg/mL and slight oxidative DNA damage both at 4 and at 24 h; increased release of IL-6 only at the lowest concentration after 24 h. The results show lack of cytotoxicity, early moderate genotoxicity and slight inflammatory effects at the lowest used concentration. These findings represent the first data on potential genotoxic, oxidative and inflammatory effects of LTA NZs and highlight the need to perform further studies to confirm such results.

Prevalence of work related musculoskeletal disorders in Italian workers: is there an underestimation of the related occupational risk factors?

BACKGROUND: Work-related musculoskeletal disorders (WMSDs) represent an important socio-economic burden. The current risk assessment and management involved in the ethiopathogenesis of WMSDs is based on observational tools and checklists, which have some limitations in terms of accuracy and reliability. The aim of this study was to assess WMSD prevalence and identify possible correlations with several socio-demographic and work-related variables in a large cohort representative of Italian workers in order to improve our understanding of the WMSD phenomenon. METHODS: This study includes data from INSuLa, a cross-sectional nationally representative survey of health and safety at work, developed by the Italian Workers' Compensation Authority. A total of 8000 Italian workers were included. Multivariate logistic regression analyses were performed to evaluate the association of independent variables, such as workers' perceptions of exposure to biomechanical/ergonomic and video display unit (VDU) risks (Risk Perceived) and the actual risk exposure (Risk Detected) on Back, Lower and Upper limb pain. Socio-demographic, occupational and other health-related variables were included to investigate possible association with musculoskeletal disorders. RESULTS: Workers perceiving a significant exposure to biomechanical/ergonomic and VDU risks but not included in a health surveillance program for them (Risk Perceived/No Risk Detected) have had significantly higher odds of reporting musculoskeletal disorders. Regarding the biomechanical/ergonomic risk these workers are in the 19-24 age range (39.9%), transportation, warehousing/information and communication sectors (38.9%) and are employed in companies with more than 250 workers (35.8%). Regarding VDU risk, workers are in the 45-54 age range (24.5%), professional, financial and business services (38.0%) and come from companies with more than 250 employees (25.6%). CONCLUSIONS: Within the occupational safety and health management systems an appropriate assessment of occupational risk factors correlated to musculoskeletal disorders (mainly biomechanical/ergonomic and VDU) and the correct definition of their exposure levels is essential to adequately prevent the onset of WMSDs. In this regard, our findings provide useful information to design novel approaches, aimed at improving our understanding of emerging risks, identifying gaps in current risk assessment strategies and enhancing workplace interventions are mandatory to improve the occupational risk assessment and management process and therefore implement the subsequent health surveillance systems.

The Sensor-Based Biomechanical Risk Assessment at the Base of the Need for Revising of Standards for Human Ergonomics.

Due to the epochal changes introduced by "Industry 4.0", it is getting harder to apply the varying approaches for biomechanical risk assessment of manual handling tasks used to prevent work-related musculoskeletal disorders (WMDs) considered within the International Standards for ergonomics. In fact, the innovative human-robot collaboration (HRC) systems are widening the number of work motor tasks that cannot be assessed. On the other hand, new sensor-based tools for biomechanical risk assessment could be used for both quantitative "direct instrumental evaluations" and "rating of standard methods", allowing certain improvements over traditional methods. In this light, this Letter aims at detecting the need for revising the standards for human ergonomics and biomechanical risk assessment by analyzing the WMDs prevalence and incidence; additionally, the strengths and weaknesses of traditional methods listed within the International Standards for manual handling activities and the next challenges needed for their revision are considered. As a representative example, the discussion is referred to the lifting of heavy loads where the revision should include the use of sensor-based tools for biomechanical risk assessment during lifting performed with the use of exoskeletons, by more than one person (team lifting) and when the traditional methods cannot be applied. The wearability of sensing and feedback sensors in addition to human augmentation technologies allows for increasing workers' awareness about possible risks and enhance the effectiveness and safety during the execution of in many manual handling activities.

[Nanomaterials and occupational health: the INAIL research contribution for responsible innovation and risk prevention for workers in Italy]. / Nanomateriali e salute sul lavoro: il contributo dell'INAIL alla ricerca per l'innovazione responsabile e la tutela dei lavoratori in Italia.

SUMMARY: In the last years nanotechnologies and nanoproducts are constantly growing up thanks to their promising benefits for social and economic development. Nanomaterials are increasingly used in our daily life, finding application in many sectors such as textile, automotive, electronic, food, etc. In 2012, the European Commission included nanotechnologies among the Key Enabling Technologies (KETs), which provide the basis for innovation in the present century. In parallel to the growing interest at industrial and production level (estimated at about 11 million of tons per year) the number of workers potentially exposed in all nanomaterials life cycle has increased. Concurrently, concerns about the potential effects on human health arose, attracting the attention by the scientific community, in particular on health and safety issues in workplaces. In Italy the industrial market has evolved in the same direction with important economic investments both public and private. Consequently, numerous research groups belonging to the University, Institutions and Research Centers were involved in the study of the main issues to promote a responsible development of nanomaterials. In this framework, the main aim of this study is to highlight the commitment of Italian research in the field of health and safety of engineered nanomaterials, through the initiatives of Italian Workers Compensation Authority (INAIL) for sustainable development of nanotechnologies.

Efficacy of sodium hypochlorite in the degradation antineoplastic drugs by NMR spectroscopy.

SUMMARY: Antineoplastic drugs are used to treat cancer, having their therapeutic effect by inhibiting the cell division process. Although cancer cells, due to their rapid growth, are more sensitive to the toxic effects of chemotherapeutic agents, healthy cells and tissues may also be damaged. Many studies show acute and chronic toxicity both in patients treated with chemotherapy and in exposed workers. In fact, exposure to these substances can also be linked to the formation of different types of secondary tumors. The International Agency on Research on Cancer (IARC) included some antineplastic drugs in Group 1 (carcinogenic to humans), in Group 2A (probable carcinogens for In recent years, many studies have evidenced the presence of antineoplastic drug contamination on work surfaces, materials and floors and based on these observations, international and national guidelines have been published to limit occupational exposure, with particular attention to procedures post-preparation of chemotherapy to limit as much as possible the accumulation of contaminated residues. The aim of the following study is to determine the effectiveness of the degradation of four antineoplastic drugs: 5-fluorouracil, azacitidine, cytarabine and irinotecan using a low concentration of sodium hypochlorite solution (0.115%). The analytical platform used to monitor the degradation course of the substances under examination was hydrogen nuclear magnetic spectroscopy (1H NMR). In the same experimental conditions the effectiveness of the degradation of the same antineoplastic drugs with a 99.9% ethanol solution was also evaluated. The study showed that the best degradation efficiency (> 90% ) is obtained with the hypochlorite solution after 15 minutes.

The management of psychosocial risks at work: state of the art and future perspectives.

BACKGROUND: Psychosocial risk management represents a current challenge in Occupational Health and Safety (OSH) due to their impacts of such risks on work stress and the rapid changes of the world of work. An effective psychosocial risk management can be carried out on the basis of an integrated multidisciplinary model founded on the risk management paradigm. Over years, the occupational medicine has played an important role at national level in this area, contributing to the creation of an integrated and participatory approach. OBJECTIVES: This study explores the developmental process of psychosocial risk management over time in Europe and Italy, to offer an update on the state of the art at a national level and insights on future perspectives. METHODS: Through a reflection on research developments, in Europe and in Italy, we outline how the knowledge obtained has been translated into policies, which have encouraged the implementation at international and national level of consolidated practices for the management of psychosocial risks. RESULTS: An overview of some key steps of the inclusion of psychosocial aspects in OSH is presented, highlighting the positive impact of the multidisciplinary approach. Moreover, the driving role played by policies for implementation in organizational practice is also highlighted, with particular reference to the Italian example. DISCUSSION: Starting from the existing knowledge, it is necessary to tackle emerging risks by continuing to translate the knowledge obtained from research into policies that have a driving role in the identification and implementation of actions and practical tools.

Assessment of exposure to cobalt and its compounds in Italian industrial settings.

BACKGROUND: Adverse health effects of occupational exposure to cobalt and its compounds are well-documented. OBJECTIVES: The aim of the study is to evaluate exposures to cobalt in Italian industrial settings. METHODS: Data on cobalt and its compounds were collected from an occupational exposure registry. Statistical analysis was carried out for some exposure-related variables (i.e., cobalt compound, activity sector, occupational group, firm size). The number of workers potentially exposed was estimated for selected industrial sectors. RESULTS: Overall 1,701 measurements were analyzed in the period 1996-2016. The geometric mean of cobalt airborne concentration was 0.33 µg/m3. Most exposures occurred in the manufacture of fabricated metal products (50%) and among metal finishing-, plating- and coating-machine operators (42%). A total of 30,401 workers potentially exposed to cobalt was estimated, over 72% were male. CONCLUSIONS: Identifying professional groups at high-risk of exposure can help to control the most dangerous situations for workers' health. Surveillance systems based on occupational exposure registries contribute to support systematic improvement of working conditions.
