Telework and its effects on mental health during the COVID-19 lockdown.

OBJECTIVE: During the Covid-19 pandemic, many governments promoted the adoption and development of telework to reduce some of the consequences of the current health crisis on the economy and favor social distancing. The aim of this web-based cross-sectional study was to assess the consequences of the Covid-19 pandemic on job organization, exploring the effects of lockdown measures on the psychological distress and perceived well-being of workers experiencing telework. SUBJECTS AND METHODS: A web-based cross-sectional survey has been used to collect data. The participants answered the questionnaire from April 1 to April 30, 2020. The questionnaire consisted of three sections, which investigated: 1) demographic and occupational variables, 2) lifestyle and habits variables, 3) psychological distress and perceived well-being. The General Health Questionnaire (GHQ-12) has been used to evaluate psychological distress and the 5-item World Health Organization Well-Being Index (WHO-5) to explore subjective well-being. RESULTS: Psychological distress was associated with educational level, with habits, and with reporting poor well-being. Poor well-being was associated with a higher job demand during pandemic, lifestyle and habits variables, and psychological distress. CONCLUSIONS: This is one of the first studies exploring the consequences of the COVID-19 pandemic and lockdown measures on the perceived well-being and psychological distress of workers experiencing telework. It is mandatory to pay more and more attention to the mental health of teleworkers, considering the increasing diffusion and adoption of this type of work organization.

Work-Related Stress Questionnaire (WRSQ): a new tool to assess psychosocial risks at workplaces.

INTRODUCTION: Work-related stress (WRS) can harm both physical and mental health but it shouldn't only be considered in its negative sense. The evaluation of WRS cannot be separated from the analysis of the subjective perception of workers, usually made by questionnaires. The aim of this pre-pilot study is to identify a new questionnaire capable of exploring as many psychosocial risk domains as possible and with a high internal consistency. MATERIAL AND METHODS: A first version of the questionnaire was administered to a convenience sample selected on a voluntary basis; both socio-demographic and work-related data were collected. A single item test was conducted on a group of 50 workers in order to assess whether the questions were confusing and to understand if they could be improved. The study sample completed the questionnaire at time 1 and time 2 (after 3 days). The 33-item version of the questionnaire was web-based in Google Form. Cronbach's alpha and Pearson's r were calculated. RESULTS: The analysis of the 33-item questionnaire at time 1 shows an excellent reliability with Cronbach's alpha coefficients of 0.93. At time 2 Cronbach's alpha coefficients was 0.94. Based on the test-retest score, the items with the highest scores were selected as part of the final version of the questionnaire (10-item). The reliability of this 10-items version is high with a Cronbach's alpha coefficients of 0.86 both at time 1 and at time 2. Two items have been chosen to explore the "emotional demand" and "dealing with technology". CONCLUSIONS: The pre-pilot study provided a questionnaire with high reliability and high repeatability. In its final version, the questionnaire investigates different psychosocial risk domains and represents a possible useful tool for assessing worker's exposure to them. The Authors reserve to administer the questionnaire to a larger population.

Work-related stress risk and preventive measures of mental disorders in the medical environment: an umbrella review.

OBJECTIVE: Work-related stress (WRS) is widespread among medical doctors. WRS not only affects the physician's mental and physical well-being, but also patient care quality and the overall efficiency of the healthcare system. The aim of this study is to conduct a systematic review of the current preventive measures against mental disorders, work-related stress, and burnout among physicians. MATERIALS AND METHODS: The presentation of this systematic review is in accordance with the PRISMA statement. The methodological quality of the selected studies was assessed with specific rating tools: INSA, Newcastle Ottawa Scale, JADAD scale, and AMSTAR. English publications only were selected. No restrictions applied for publication type. Reviewers excluded articles not concerning the following topics: WRS prevention, WRS risk factors and mental disorders among physicians. Reviewers also excluded findings of less academic significance, editorial articles, individual contributions, purely descriptive studies published in scientific conferences. RESULTS: Online search returned 4748 references on the following databases: PubMed (1638), Scopus (3108) and Cochrane Library (2). 36 studies were included in this review (thereof, 13 reviews and 23 original articles). Narrative reviews were rated on the INSA scale. The mean, median, and modal rating was 6. This indicates an intermediate-high quality of these studies. Systematic reviews were rated on the AMSTAR scale. The mean and median rating was 9, and the modal rating was 8. This indicates a high quality of these studies. The scores assigned to the original articles have a mean, median, and modal rating of 7. This also indicates an intermediate-high quality of these studies. CONCLUSIONS: Work-related stress and mental disorders seem to be widespread among medical practitioners. It is already a priority to adopt preventive measures against these phenomena. However, there is still no consensus on what the most effective measures are. Additional research is needed to formulate evidence-based recommendations.

Bullying at work and work-related stress in healthcare workers: a cross sectional study.

BACKGROUND: Bullying is a serious and growing problem affecting a significant proportion of healthcare professionals, a professional category exposed to work-related stress. Workplace bullying has been defined as a set of negative behaviours consisting in harassment, offense or negative influence on work that are directed to the members of the organization and that occur regularly and repeatedly over a period, becoming part of the context of work. STUDY DESIGN: We performed a cross-sectional study using the HSE questionnaire and defining the sample size considering the number of healthcare workers of a big hospital and then calculating it with EpiInfo™ software. 191 people have been enrolled. METHODS: The study was divided into three steps. The first one to identify, among the workers, those who were exposed to bullying at work and those who were not. The second one has been aimed at assessing the presence of work-related stress through the administration of the HSE questionnaire. The third step has been aimed at performing the statistical analysis of the data. For each single domain explored by the questionnaire the score obtained was treated as a linear variable and the median and interquartile range (IQR) was calculated. After, a non-parametric analysis (Wilcoxon rank-sum test) was performed in order to define the statistical significance of the observed differences. RESULTS: All the 191 questionnaires were self-administered by the Health Care Workers under study and correctly filled in without any multiple or missing responses. Considering the scores obtained to question n. 21, that investigates "bullying at work", we obtained two groups: High-Exposure Group (total, males and females), and Low-Exposure Group (total, males and females). In the High-Exposure Group, two critical domains were found: Demands and Control (total, male and female samples). The differences with the Low-Exposure Group were statistically significant. In the Low-Exposure Group the critical domain was Manager Support (total and female samples). The differences with the High Exposure Group were not statistically significant. CONCLUSION: This study aimed to show how the exposure to bullying can influence the perception of psychosocial risks. It seems that the workers most exposed to bullying also have worse scores on the HSE questionnaire, particularly for two domains: Demands and Control. That is consistent with the most recent scientific literature.

Early diagnosis of hearing loss: otoacoustic emissions evoked by distortion products and pure-tone audiometry: Preliminary findings.

OBJECTIVE: Literary studies underline the effectiveness of distortion product otoacoustic emissions (DPOAEs), which are not affected by the collaboration of the subject examined, in the early diagnosis of hearing loss. Aim of the study is to compare the objective technique of DPOAEs with respect to the pure-tone audiometry in early diagnosis of hearing loss. MATERIALS AND METHODS: The clinical research was carried out on 852 workers. All subjects underwent pure-tone audiometry, tympanometry and distortion products. RESULTS: The results show: a) a prevalence of subjects with impaired DPOAEs higher than the prevalence of subjects with impaired audiometries in the studied samples; and, after division by gender: b) a prevalence of subjects with impaired DPOAEs higher than the prevalence of subjects with impaired audiometries only in men; c) a prevalence of impaired DPOAEs and of impaired audiometries in men higher than in women. CONCLUSIONS: The results suggest the higher effectiveness of DPOAEs compared to pure-tone audiometry in making an early diagnosis of hearing loss.

Liver damage in automotive and industrial workers of the glass.

OBJECTIVE: High doses of organic solvents can cause hepatic disease. We investigated whether exposure to low doses of solvents in automotive and industrial workers may lead to changes in liver tests. METHODS: We studied the liver parameters (glutamic oxaloacetic transaminase (GOT), glutamic-pyruvic transaminase (GPT), gamma-glutamyl-traspeptidasi (γ-GT), alkaline phosphatase (PHA), total (TB) and direct bilirubin (DB) of 24 workers exposed to organic solvents and of 30 unexposed controls. RESULTS: A significant increase of GOT, GPT and γ-GT was found in exposed workers compared to unexposed controls workers. The ratio GPT/GOT was significantly higher among the exposed compared to controls. CONCLUSIONS: The results confirmed the hypothesis that exposure to low doses of solvents may determine a liver damage.

Relationship between occupational exposure to cadmium, transaminases and γ-GT in workers exposed to urban stressors.

BACKGROUND: The exposure to Cd has been linked to many disease and liver is the major target organ of Cd toxicity following acute or chronic exposure.No study has ever evaluated the association between liver function tests and exposure to Cd present in urban air in outdoor workers. MATERIALS AND METHODS: In order to assess the relationship between the exposure to urban Cd and the associated changes in liver functionality markers, we conducted a study on 110 municipal policemen divided into 2 groups according to their tasks: 60 traffic policemen and 50 drivers, underwent tests for the determination of the urinary values of Cd correlated with the blood levels of transaminases and ?-GT. Moreover we investigated the exposure to Cd in the air through a personal dosimetry on a subgroup of 40 subjects (20 traffic policemen 20 police drivers). RESULTS: The results showed that the average personal exposure to air Cd was significantly higher in traffic policemen than drivers. Furthermore, in the subset of 40 subjects and in the total sample of 110 subjects, the mean values of urinary Cd were significantly higher in traffic policemen rather than in the police drivers. No significant difference was observed in the mean values of liver functionality in both groups. CONCLUSIONS: Due to the few studies on the effects of the exposure to Cd in big cities, the results of the present study offers useful information about occupational exposure to Cd on the road and in the car and the lack of effects on liver function.

[Exposure to cadmium and plasma cortisol in workers exposed to urban stressor]. / Esposizione a cadmio e cortisolo plasmatico in lavoratori esposti a stressor urbani.

OBJECTIVES: The aim of this study is to estimate the exposure to Cd in a group of roadmen compared to a group of drivers by environmental monitoring and biological monitoring of blood and urinary Cd. It aims to evaluate whether exposure to Cd can affect plasma cortisol. MATERIALS AND METHODS: The initial sample was composed by 130 employees of Municipal Police Force (roadmen and drivers). After administration of a clinical-anamnestic questionnaire were excluded 50 subjects who presented confounding factors and 30 subjects who weren't comparable. On a final sample of 25 drivers and 25 roadmen were conducted environmental monitoring of Cd, biological monitoring of urinary and blood Cd and assessment of cortisol. RESULTS: Personal exposure to Cd in air was significantly higher in roadmen compared to drivers (p = 0.015). Urinary and blood Cd were significantly increased in roadmen compared to drivers (p = 0.18 and p = 0.025). There weren't significant differences in plasma cortisol between drivers and roadmen (p> 0.05). The multiple linear regression analysis shows that urinary and blood Cd are dependent on the environment Cd levels and on the job (driver or roadmen) (p = 0.014 and p = 0.012) and plasma cortisol isn't dependent on blood and urinary Cd. CONCLUSIONS: The results show a higher concentration of Cd in roadmen both in air and urine and they don't indicate an influence of exposure to low doses of Cd on plasma cortisol.

Professional exposure to ionizing radiations in health workers and white blood cells.

BACKGROUND: The aim of this study is to estimate if low dose of occupational exposure to ionizing radiations can cause alterations of plasma concentrations of total white blood cells, lymphocytes, monocytes and granulocytes (eosinophils, basophils, neutrophils), in the health workers of a big hospital. METHODS: 266 non smokers subjects of both sexes (133 health workers and 133 controls) were included in this study, compared on the basis of sex, age and working seniority. The complete blood count (CBC) was performed in all included workers. RESULTS: The differences between the mean values were compared using Student T-test for unpaired data. The frequencies of the single variables were compared using Chi (2) test with Yates correction. The differences were considered significant when the P values were < 0.05. The mean values and the distribution of the mean values of total white blood cell were significantly decreased in health workers of both sexes compared to controls. The average values of granulocytes neutrophils were significantly low in female health workers compared to female controls. CONCLUSIONS: The obtained results suggest that low dose of occupational exposure to ionizing radiations is able to influence some lines of the hematopoietic system in exposed workers.

Perceived stress and stress-related parameters.

BACKGROUND: The purpose of this study is to evaluate, using a questionnaire developed by our research group, whether occupational exposure to physical, chemical and psychosocial urban stressors can lead to alterations in perceived stress in a group of both male and female outdoor workers. The study also examines possible correlations between the levels of stress as inferred from the scores of the questionnaire and the levels of certain stress-related parameters (prolactin levels, consumption of coffee, chocolate, alcohol and cigarette smoking). METHODS: We evaluated a final sample of 480 subjects (342 male and 138 female). All workers included in the study were divided into three groups on the basis of scores of the questionnaire. RESULTS: About 60% of workers showed a moderate or severe stress condition, with a statistically significant prevalence of female workers and younger subjects. There was a statistically significant correlation between the questionnaire score and the mean levels of stress-related parameters. The increase of perceived stress increases significantly the mean levels of prolactin and the consumption of coffee, chocolate and cigarettes. There was no statistically significant differences for alcohol consumption. CONCLUSIONS: The results show that exposure to chemical physical and psycho-social urban stressors can influence perceived stress in outdoor workers. The questionnaire used in our research could be an useful instruments for physicians during the health surveillance visits

Arsenic and peripheral blood count in workers exposed to urban stressors.

OBJECTIVES: Previous studies have shown that arsenic at high doses can alter the hematopoietic system. The purpose of the present study is to see whether the same problems may be caused by chronic exposure to low doses. MATERIALS AND METHODS: A sample of 349 policemen of a big urban city was divided into 3 groups according to levels of urinary arsenic. The subjects were further divided according to gender, smoking habits, and work task. We calculated indices of correlation (r) and multiple linear regression (ß), between urinary arsenic, RBC, WBC, HB, HT, MCV, MCH, MCHC, platelets, reticulocytes and leukocyte formula (percentage of lymphocytes, monocytes, neutrophils, eosinophils and basophils). It was also calculated Student's t and chi-square test between the various groups to check for any differences. RESULTS: We found several statistically significant indices of correlation and regression (p(two-tailed) <0.05) between urinary arsenic, red blood cells, white blood cells, hemoglobin, hematocrit, reticulocytes, and all the cell lines of the white series. CONCLUSIONS: Chronic exposure to low doses of arsenic seems to cause decrease in red blood cells, hematocrit and hemoglobin. However, this response is dependent on the amount of absorbed dose, according to an ormetic mechanism. With regard to the white series, arsenic seems to provoke an inflammatory response; the scarcity of literature" available, and the great variety of results, however, not allow us to definitely characterize the damage caused by this metal on white series.
