The aim of this research is to summarize the current knowledge regarding the application of augmented reality in occupational safety training programs, particularly in the healthcare sector. Three databases (PubMed, Scopus, Web of Science) were searched for articles published between 1992 and 2017 on health and safety training for healthcare professionals, with particular attention to the use of augmented reality; for this purpose, a search string was created. Augmented reality represents a great opportunity in the training of health workers, being able to implement the workers’ knowledge and perception of the risks. It is therefore important to have a multidisciplinary approach that manages the opportunities and risks of these new tools in a well-defined framework, increasingly taking advantage of the former and reducing the latter, to guide health care workers in adopting correct and safe behaviours that favour the reduction of injuries and occupational diseases.

The study aimed to investigate the tobacco smoking prevalence, habits and awareness among a cohort of healthcare students from a university hospital in southern Italy and the associations with socio-demographic determinants. A secondary outcome was to estimate the educational needs to receive information on smoking-related risk factors. Five hundred and forty-nine students completed a self-administered questionnaire (180 male and 369 female, average age 25 yo, ±5.9 SD), enrolled from October 2018 to November 2019 at the University of Naples ‘Luigi Vanvitelli’, and the collected data were analysed by descriptive and inferential statistical analysis. The sample’s prevalence of current smokers was 25.3%, without a significant sex difference. The multiple logistic regression model showed the link between smoking habits and alcoholic beverage consumption (p < 0.001) and living with smokers (p = 0.003). The enrolled cohort does not seem to need more information about the risks of cigarette smoking (p = 0.028). The data analysis and the comparison with the current literature allowed the authors to hypothesise a training model to be adopted within a workplace health promotion programme managed by an occupational physician. This model included targeted training for smoking dissuasion, focusing on sex and gender, cohabitant’s influence, and combined addiction management. Further research will focus on the effectiveness of these proposed models.

Objective: The development of a vaccine against hepatitis B virus (HBV) is one of the improvements in strategy prevention during the last decades. Aim: To evaluate HBV-related vaccine status in healthcare workers (HCW) exposed to biological risk. Methods: The serum markers for HBV were collected from HCWs in two tertiary care hospitals in Naples (Italy). Multivariate statistical analysis was then performed to identify associated factors linked to the long-term immunogenicity of the HCWs. Results: All HBV vaccinated individuals were screened for whole marker patterns; all were HBsAg/anti-HBc negative. Of individuals, 20% had an anti-HB antibody titre < 10 IU/L. Multivariate statistical analysis highlighted that women were more protected than men (73.6% vs. 26.4%, P < 0.05). Additionally, nurses seem to maintain a higher antibody titre than doctors and other staff, such as auxiliary technicians ( P < 0.05). Conclusions: Our data support the evidence of a strong immunogenicity against HBV, assessed through the circulating antibody titre, when prophylactic vaccination is conducted in non-infantile age, particularly for women. The outcome of the study supports the central role of occupational physicians within the hospital districts in terms of primary prevention and maximum protection of HCWs.

Healthcare workers are at an increased risk of contracting Mycobacterium tuberculosis infection. Tuberculin skin test (TST) and interferon gamma release assay (IGRA) represent the available tests most used for the diagnosis of latent tuberculosis infection (LTBI). Different borderline zones have been proposed for defining conversions and reversions to improve the interpretation of the IGRA test results as part of serial testing. From 2012 to 2017, 5468 health students of an Italian University Hospital were screened for tuberculosis infection through the execution of the TST and, in case of positivity, of the QuantiFERON-TB&reg, Gold In-Tube assay (QFT&ndash, GIT). The QFT&ndash, GIT is considered &ldquo, borderline&rdquo, with values from 0.35 to 0.99 IU/mL. Among the students who performed the QFT&ndash, GIT assay, 27 subjects presented a range of values defined as borderline. The QFT&ndash, GIT was repeated after 90 days on 19 subjects with borderline values and showed a negativization of the values in 14 students and a positive conversion in three cases, while for two students, a borderline value was also found for the second test, with a 74% regression of the borderline cases. The introduction of QuantiFERON borderline values is a useful assessment tool to bring out LTBI case candidates for chemoprophylaxis.

Objective To estimate the three-year cumulative risk of work-related upper limb disorders (WRULDs) in a cohort of automotive industry workers and to provide a first test of the ability of the European Assembly Worksheet (EAWS) methodology to predict WRULDs. Methods 292 workers were investigated by reviewing workers' medical records during the period from 2012-2015 to determine their exposure to biomechanical overload according to EAWS risk scores (0-25, low risk, Green zone; 26-50, medium risk, Yellow zone; >50, High risk; Red zone). Results The risks were 0.83%, 5.71%, and 11.88% for the Control (unexposed), Green and Yellow Groups, respectively. Only the comparison between the Yellow/Control Groups was significant (p = 0.0014). In total, we observed 17 cases of musculoskeletal disorders (MSDs) (14 symptomatic and 3 cases detected by physical examination). Conclusions The EAWS is a useful tool for the preliminary risk assessments of biomechanical overload among automotive industry workers. The finding of mainly non-specific disorders highly suggests that health surveillance should aim to identify not only full-blown diseases but also symptomatic cases.

Manual patient handling (MPH) is a major occupational risk in healthcare settings. The aim of this study was to propose an MPH training model involving interdisciplinary aspects. A scheduled training program was performed with 60 healthcare workers (HCWs) from a hospital in Naples, Italy, providing training divided into three sections (occupational health&mdash, section one, physical therapy&mdash, section two, psychosocial section&mdash, section three) and lasting six hours. Fifty-two HCWs performed the training session. In section one, a questionnaire about risk perception related to specific working tasks was administered. Section two provided specific exercises for the postural discharge of the anatomical areas most involved in MPH. The last section provided teamwork consolidation through a role-playing exercise. The training program could also be useful for risk assessment itself, as they can examine the perceptions of the specific risk of the various workers and incorrect attitudes and therefore correct any incorrect procedures, reducing exposure to specific risks in the field. This pilot study proposes a training model that explores all aspects related to MPH risk exposure and also underlines the need for standardization of this formative model, which could represent a useful tool for studying the real effectiveness of training in workplaces.

Biomechanical overload represents one of the main risks in the industrial environment and the main possible source of musculoskeletal disorders and diseases. The aim of the this study is to introduce new technologies for quantitative risk assessment of biomechanical overload, by integrating surface electromyography (sEMG) with an innovative motion-capture system based on inertial measurement units (IMU). The case study was carried out in collaboration with Fiat Chrysler Automobiles Italy S.p.A. and deals with the analysis of the “central tunnel cabinet assembly” activity, performed by two workers of assembly lines during a working task, which lasts about one minute. The electromyography signals were acquired bilaterally, in three different body regions on the right and on the left side of the Erector Spinae, during standard working activities; the progression of trunk postures (flexion-extension, lateral flexion and twisting) was tracked by using an inertial motion-capture system made of wearable inertial sensors, to evaluate the alignment of the major body segments, using a developed algorithm. Data analysis showed kinematic and muscular activity patterns consistent with the expected ones. In particular, data show that the proposed technologies can be integrated and simultaneously used during workers’ real performing activities. Data quality also demonstrates that both types of sensors, EMG electrodes and IMU, not influenced each other, neither by electromagnetic noise usually present in an industrial environment. The results of this study show feasibility and usefulness of the integration of kinematic and electromyography technologies for assessing the biomechanical overload in production lines.

Objective A systematic review and meta-analysis was conducted to evaluate the agreement between Tuberculin Skin Test (TST) and Quantiferon (QFT) in screening for tuberculosis (TB) infection among healthcare workers (HCWs) and to estimate associations between TST and QFT agreement and variables of interest, such as Bacillus Calmette-Guérin (BCG) vaccination and incidence of TB. Methods Cross-sectional and longitudinal studies on HCWs, published in English until October 2013, comparing TST and QFT results, were selected. For each study Cohen’s κ value and a 95% confidence interval were calculated. Summary measures and indexes of heterogeneity between studies were calculated. Results 29 studies were selected comprising a total of 11,434 HCWs. Cohen’s κ for agreement between TST and QFT for 24 of them was 0.28 (95% CI 0.22 to 0.35), with the best value in high TB incidence countries and the lowest rate of BCG vaccination. Conclusion Currently, there is no gold standard for TB screening and the most-used diagnostic tools show low agreement. For evidence-based health surveillance in HCWs, occupational physicians need to consider a number of factors influencing screening results, such as TB incidence, vaccination status, age and working seniority.
