Background: Fatigue is also an important occupational condition for hairdressers.

Objective: The purpose of this study was to determine the lower extremity fatigue and related factors in hairdressers.

Methods: Lower Extremity Fatigue was assessed with 2 questions containing a 5-point Likert scale. Numerical fatigue rating scale was used to assess general fatigue level, visual analogue scale was used to assess occupational satisfaction, Nottingham Health Profile (NHP) was used to assess health profile, and Cornell Musculoskeletal Discomfort Questionnaire (CMDQ) was used to assess lower quadrant pain profile.

Results: In the assessment of lower extremity pain, statistically significant difference was found between Fatigue and Non-fatigue groups in waist (p:0.018), right knee (p:0.020), left knee (p:0.019) and right lower leg (p:0.023) parameters. In the lower extremity Weighted Scores, there were significant differences between the fatigue and non-fatigue groups in waist (p:0.0001), right upper leg (p:0.018), left upper leg (p:0.009), right knee (p:0.0001) left knee (p:0.0001), right lower leg (p:0.001) and left lower leg (p:0.002). The difference in the Energy, Pain and Physical Mobility sub-dimensions of the Nottingham Health Profile of the hairdressers in 'Fatigue Group' was at a significant level.

Conclusions: In conclusion, the rate of lower extremity fatigue found in hairdressers in the present study was quite high and lower extremity fatigue was associated with lower extremity pain and health profile.

Background: An increased risk of mesothelioma has been reported in various countries for construction workers. The Italian National Mesothelioma Registry, from 1993 to 2018, reported exposure exclusively in the construction sector in 2310 cases. We describe the characteristics of these cases according to job title.

Methods: We converted into 18 groups the original jobs (N=338) as reported by ISTAT codes ('ATECO 91'). The exposure level was attributed at certain, probable and possible in accordance with the qualitative classification of exposure as reported in the Registry guidelines. Descriptive analysis by jobs highlights the total number of subjects for each single job and certain exposure, in descending order, insulator, plumbing, carpenter, mechanic, bricklayer, electrician, machine operator, plasterer, building contractor, painter and labourer.

Results: The cases grow for plumbing in the incidence periods 1993-2018, while, as expected, it decreases for insulator. Within each period considered the most numerous cases are always among bricklayers and labourers, these data confirm the prevalence of non-specialised "interchangeable" jobs in Italian construction sector in the past.

Conclusions: Despite the 1992 ban, the construction sector still presents an occupational health prevention challenge, circumstances of exposure to asbestos may still occur due to incomplete compliance with prevention and protection measures.

Background: The construction industry has a percentage of work-related injuries and fatalities. Workers' perception of occupational hazards exposure can be a proactive management tool in knowing the state of construction site safety performance. This study aimed to assess the hazard perception of on-site construction workers in Ghana.

Methods: Using a structured questionnaire, data was collected from 197 construction workers at live building sites in the Ho Municipality. The data were analyzed using the Relative Importance Index (RII) approach.

Results: The study revealed that on-site construction workers perceived ergonomic hazards as the most frequent, followed by physical, phycological, biological, and chemical hazards. The importance level of RII revealed that long working hours and bending or twisting back during task performance were perceived as the most severe hazards. Long working hours had the highest overall RII ranking, followed by bending or twisting back during task performance, manual lifting of objects or loads, scorching temperatures, and lengthy standing for prolonged periods.

Conclusions: Given the adverse health effects of working for long hours, the management of Ghanaian construction industries needs to reinforce the legislation on working hours to safeguard workers' occupational health. Safety professionals can use the study's findings to improve safety performance in the Ghanaian construction industry.

Background: Health care workers (HCWs) were on the frontline of the current pandemic. We aimed at identifying determinants of SARS-CoV-2 infection and the effectiveness of personal protection equipment (PPE) worn by HCWs before vaccination.

Methods: We abstracted data on SARS-CoV-2 infection based on positive PCR results and sociodemographic characteristics of 38,793 HCWs from public hospitals and public health authorities from 10 European centers. We fitted cohort-specific multivariate logistic regression models to identify determinants of infection and combined the results using random-effects meta-analyses.

Results: The overall prevalence of infection before vaccination among HCWs was 9.58%. Infection was associated with the presence of selected symptoms; no association was found between sociodemographic factors and increased risk of infection. The use of PPE and particularly FFP2/FFP3 masks had a different protective effect during the first and second waves of the COVID pandemic.

Conclusions: The study provides evidence that mask use was the most effective PPE in preventing SARS-CoV-2 infection among HCWs.

The article discusses a recent study on mortality attributable to COVID-19 in Italy and the need for further analysis. The study used a reliable methodology to estimate excess deaths due to the pandemic. However, there are still questions about the specific effects of COVID-19 compared to other factors, such as delayed or missing access to treatment for other illnesses. Analyzing the time course of excess deaths could reveal such effects. There are also open questions about how COVID-19 deaths are classified and reported, which could lead to over or under-diagnosing cases. The article notes that occupational physicians have played an important role in preventing the spread of COVID-19 among workers. A recent study found that personal protective equipment (PPE), particularly masks, effectively reduced the risk of infection among healthcare workers. However, it is still unclear whether Occupational Medicine should incorporate infectious diseases as a major concern or return to its historically agnostic attitude toward communicable diseases. More data on mortality from specific diseases will be needed for further analysis and understanding of the pandemic's effects on mortality rates in Italy.

Background: Italy had a persistent excess of total mortality up to July 2022. This study provides updated estimates of excess mortality in Italy until February 2023.

Methods: Mortality and population data from 2011 to 2019 were used to estimate the number of expected deaths during the pandemic. Expected deaths were obtained using over-dispersed Poisson regression models, fitted separately for men and women, including calendar year, age group, and a smoothed function of the day of the year as predictors. The excess deaths were then obtained by calculating the difference between observed and expected deaths and were computed at all ages and working ages (25-64 years).

Results: We estimated 26,647 excess deaths for all ages and 1248 for working ages from August to December 2022, resulting in a percent excess mortality of 10.2% and 4.7%, respectively. No excess mortality was detected in January and February 2023.

Conclusions: Our study indicates substantial excess mortality beyond those directly attributed to COVID-19 during the BA.4 and BA.5 Omicron wave in the latter half of 2022. This excess could be attributed to additional factors, such as the heatwave during the summer of 2022 and the early onset of the influenza season.

Background: The risk of hepatitis C virus (HCV) infection among emergency responders exposed to human remains, blood/bodily fluids, and/or sewage is unknown. Methods: A cross-sectional study of 3871 World Trade Center General Responder Cohort (WTCGRC) members followed at the Icahn School of Medicine at Mount Sinai, born from 1945-1965, and recruited from 2016-2018 were tested for HCV infection, and prevalence was compared to National Health and Nutrition Examination Survey data from 2003 to 2012. A nested case-control study compared 61 HCV antibody positive cases to 2571 controls. Multivariable logistic regression models adjusting for time of birth, traditional HCV risk factors, and type of work at the World Trade Center (WTC) site, determined if contact with human remains, blood/bodily fluids, and/or sewage at the WTC site was associated with HCV infection. Results: The age-standardized point prevalence of HCV infection among WTCGRC members was 2.98% [95% CI (2.39, 3.56)] and in the US population was 3.33% [95% CI (2.54, 4.11)] [% difference = 0.35%, 95% CI (- 0.31%, 1.01%), P=0.47]. In separate multivariable models, adjusting for possible confounders, contact with human remains was not associated with HCV infection [OR = 1.10, 95%CI(0.63, 1.91), P = 0.74)], contact with blood and/or bodily fluids was not associated with HCV infection [OR = 1.45, 95%CI(0.82, 2.56), P = 0.20], and contact with sewage was significantly associated with HCV infection [OR = 1.72, 95%CI(1.00, 2.98), P = 0.05]. Conclusion: Contact with sewage may increase the risk of HCV infection.

Background: The frequent use of hand-held vibrating tools by construction workers exposes them to hand-transmitted vibration (HTV) and noise. This study investigated the effect of combined exposure to HTV and noise on workers' fatigues under simulated work with a typical building destruction tool.

Methods: The repeated measures study was conducted on 40 construction workers exposed to HTV (5 m/s2 rms with frequencies of 31.5, 63, and 125 Hz), HTV (10 m/s2 rms- 31.5 Hz), noise (90 dBA), and concurrent exposure (noise (90 dBA) + HTV (10 m/s2 rms- 31.5 Hz)) with the typical vibrating hand-held tool for 30 minutes. Electromyography signals determined each worker's fatigue level in the Flexor digitorum superficialis (FDS) muscle in two pre- and post-exposure periods. The subjects also filled out the visual analog scale to evaluate mental fatigue severity subjectively.

Results: The mean difference of muscle fatigue parameters was significant in all scenarios except for the two scenarios of alone exposure to HTV (5 m/s2 -125 Hz and noise exposure (p-value < 0.05). The mean difference of mental fatigue in all scenarios except for the two scenarios of exposure to HTV (5 m/s2 -125 Hz) and exposure to HTV (5 m/s2 -63 Hz) was significant (p-value < 0.05). The most differences in muscle fatigue parameters (Amplitude = 8.16±5.63, Mean frequency=-4.69±3.78) and mental fatigue (4.97±2.38) were observed in the simultaneous exposure to noise and HTV.

Conclusion: Noise exposure alone cannot produce remarkable effects on muscle fatigue but can aggravate the effects of vibrations as a consequence of synergistic interaction. However, the role of noise on perceived mental fatigue was more dominant than the HTV. These findings should be considered to adapt the existing exposure limits to actual work conditions.

Background: The COVID-19 pandemic created an extremely difficult situation for healthcare workers (HCWs) worldwide. We aimed to compare the mental health and professional quality of life of residents and specialist physicians in a cohort of Italian HCWs caring for patients with COVID-19 about two years after the start of the COVID-19 pandemic.

Methods: In November 2021, an online survey investigating the emotional states of depression, anxiety, stress, compassion satisfaction and compassion fatigue was administered to HCWs (N= 78) at the Fondazione Policlinico Universitario A. Gemelli IRCCS, Rome.

Results: Our findings suggest that from 5 to 20% of our cohort of HCWs still showed the effects of the adverse psychological impact of the pandemic and more than half of them experienced medium levels of compassion fatigue as well as a medium level of compassion satisfaction. Our results also show that those with fewer years of clinical practice might be at greater risk of burnout (p= 0.021), anxiety and stress symptoms (both ps= 0.027) and might develop a lower level of compassion satisfaction (p=0.018). Moreover, the factors that potentially contribute to poor mental health, compassion fatigue and compassion satisfaction seem to differ between residents and specialist physicians.

Conclusions: This overview presents one of the first pictures of the long-term effects of the pandemic on the mental health and professional quality of life of an Italian sample of HCWs. Moreover, it also helps identify professionals who are most in need of support and emphasises the importance of improving the psychological and professional wellbeing of these individuals especially during a pandemic-like crisis with long lasting effects.

Background: To examine firefighters (FFs) exposed to high levels of fire smoke and, as a result, to uncover risk factors for dry eye disorder (DED) compared to age-and gender-matched healthy individuals.

Methods: In this cross-sectional study, 51 FFs from the Afyonkarahisar Municipality Fire Department were chosen at random (group 1). A control group (group 2) included 51 age- and gender-matched healthy individuals. The Ocular Surface Disease Index (OSDI) questionnaire was administered after all participants were thoroughly explained the study's objectives and procedures. Then, using a portable hand biomicroscope, an ocular exam was performed on-site. DED was defined as a non-anesthetic Schirmer test result of <10 mm and/or a tear film break-up time (TBUT) of <5 seconds.

Results: Groups 1 and 2 had mean ages of 44.82±7.29 and 44.73±7.41 years, respectively (p=0.946). The median work duration in group 1 was 14 years (min-max: 1-27 years). TBUT test revealed a significantly increased DED prevalence in group 1 than group 2 (p=0.046). Despite the non-significant difference (p=0.276), Schirmer test revealed that group 1 had a higher DED prevalence than group 2. The OSDI score revealed that group 1 had more mild, moderate, and severe DED than group 2 (p=0.359). Longer work duration was associated with a higher DED prevalence (p=0.179).

Conclusions: Given the high prevalence of fire smoke-induced DED in FFs, preventive measures such as regular ocular exams, encouraging personal protective equipment usage, and health education programs can assist in avoiding complications and reducing the burden of ocular diseases.
