Cost and Cost-Effectiveness of the Mediterranean Diet: An Update of a Systematic Review.

It is well known that the Mediterranean diet (DM) is beneficial for health, as years of research globally have confirmed. The aim of this study was to update a previous systematic review that assessed the cost-effectiveness of adherence to the DM as a strategy for the prevention of degenerative diseases by evaluating the economic performance of this diet. The research approach utilized three electronic databases: PubMed, Scopus, and Web of Science. A comprehensive search was conducted to retrieve articles based on a PRISMA-compliant protocol registered in PROSPERO: CRD 42023493562. Data extraction and analysis were performed on all included studies. One thousand two hundred and eighty-two articles were retrieved, and once duplicates and irrelevant articles were removed, fifteen useful articles were reviewed. The studies indicated a clear link between dietary habits, health, and economic aspects related to dietary cost and health spending. Recognizing the significant health benefits associated with adopting DM and the potential savings on health care spending, it is important for national public health programs to consider policies that support this lifestyle.

Mini-Z validation for burnout and stress evaluation: an observational study.

BACKGROUND: The Mini-Z is a questionnaire created to evaluate the levels of burnout in healthcare workers. It consists of 10 items rated using a 5-point Likert scale and one open question. It explores three outcomes (burnout, stress and satisfaction) and seven drivers of burnout (work control, work chaos, teamwork, values alignment with leadership, documentation time pressure, EMR use at home, and EMR proficiency). The aim of this study is to validate the Italian version of the Mini-Z, comparing it with the other most used scales. MATERIALS AND METHODS: We recruited a sample of 120 healthcare professionals and administered all three questionnaires to each of them, after which we compared the answers and the scores of the results. A cross-sectional study among healthcare workers was conducted from May to July 2022. An online questionnaire was sent, by e-mail, to 120 healthcare workers (60.8% male, 39.2% female), aged between 18 and 60 years old (26.8% between 25 and 38 years old). They were invited to answer to an anonymous survey, consisting of three assessment instruments: Copenhagen Burnout Inventory (CBI), Maslach Burnout Inventory (MBI) and Mini-Z Inventory 2.0. The Mini-Z 2.0 is a new and easier tool to assess burnout syndrome, actually validated only in English. It was translated into Italian by reverse translation. Cronbach's Alpha coefficient, a statistical index, was used to assess its reliability. The last phase of the study compared the Mini-Z, the CBI and the MBI, by means of Pearson's coefficient, to highlight the Mini-Z's ability to be used for Burnout assessment. RESULTS: The analysis of the results showed that 18.3% of the interviewed healthcare professionals scored equal (2.5%) or higher (15.8%) than 40. The average percentage value was 33.35%, with a standard deviation of 6.3%. This emphasises, therefore, that this portion of employees is more or less satisfied with their working environment. The remaining portion of employees, on the other hand, 81.7%, scored below 40, emphasising an unpleasant and unjoyful working environment. DISCUSSION AND CONCLUSIONS: Burnout is very common among employees and especially among healthcare workers and a routine assessment seems to be necessary to be able to prevent the syndrome. The Italian version of the Mini-Z includes ten items, is more user-friendly and aims to assess not only Burnout subscales, as in the previous tests, but also well-being factors and has applied a rigorous approach, including forward translation, back translation and cognitive debriefing.

Workplace Bullying in Italy: A Systematic Review and Meta-Analysis.

BACKGROUND: Within any work environment, employees may be affected by "workplace bullying", a form of violent and repeated social behavior towards subordinates and colleagues. This review aimed to investigate the prevalence of bullied workers in Italy, the causes of the phenomenon, and the consequences at physical, psychological, and organizational levels. METHODS: We included observational studies and systematic reviews examining the prevalence of bullied workers and the causes and consequences in Italian workplaces. Data extraction and analysis were performed on all included studies. The research strategy included three electronic databases (PubMed, Scopus, and Web of Science). A comprehensive search was done to retrieve articles based on a PRISMA-compliant protocol registered in PROSPERO: CRD 42023394635. RESULTS: One hundred eighty-four articles were retrieved, and once duplicates and irrelevant articles were removed, 42 useful articles were reviewed. The mean pooled prevalence, calculated based on workers complaining of mistreatment, was 6.7% (SD: 4,09) and increased significantly to 17.0% (SD: 12.88) when considering only healthcare workplaces. Causes include how impaired mental health and high workload reinforce the possibility of being bullied in the workplace, resulting in a worsening of the worker's quality of life (physical and psychological) and the work organization with increased absenteeism and job changes. CONCLUSIONS: Workplace bullying is a very present phenomenon within workplaces in Italy. In light of this, it is necessary to put prevention plans in place and find solutions to maintain optimal organizational well-being in the work environment.

Evaluation of the Factors Associated with Reinfections towards SARS-CoV-2 Using a Case Control Design.

OBJECTIVE: The risk of reinfection with SARS-CoV-2 has been rapidly increased with the circulation of concerns about variants. So, the aim of our study was to evaluate the factors that increase the risk of this reinfection in healthcare workers compared to those who have never been positive and those who have had only one positivity. METHODS: A case-control study was carried out at the Teaching Hospital Policlinico Umberto I in Rome, Sapienza University of Rome, in the period between 6 March 2020 and 3 June 2022. Cases are healthcare workers who have developed a reinfection with the SARS-CoV-2 virus, while controls were either healthcare workers who tested positive once or those who have never tested positive for SARS-CoV-2. RESULTS: 134 cases and 267 controls were recruited. Female gender is associated with a higher odds of developing reinfection (OR: 2.42; 95% CI: 1.38-4.25). Moreover, moderate or high alcohol consumption is associated with higher odds of reinfection (OR: 1.49; 95% CI: 1.19-1.87). Diabetes is also associated with higher odds of reinfection (OR: 3.45; 95% CI: 1.41-8.46). Finally, subjects with increased red blood cell counts have higher odds of reinfection (OR: 1.69; 95% CI: 1.21-2.25). CONCLUSION: From the prevention point of view, these findings indicate that particular attention should be paid to subjects with diabetes mellitus, women and alcoholic drinkers. These results could also suggest that contact tracing represents a fundamental approach model against the SARS-CoV-2 pandemic, together with the health information of participants.

Synergistic Effect between SARS-CoV-2 Wave and COVID-19 Vaccination on the Occurrence of Mild Symptoms in Healthcare Workers.

BACKGROUND: Since the beginning of the pandemic, five variants of epidemiological interest have been identified, each of them with its pattern of symptomology and disease severity. The aim of this study is to analyze the role of vaccination status in modulating the pattern of symptomatology associated with COVID-19 infection during four waves. METHODS: Data from the surveillance activity of healthcare workers were used to carry out descriptive analysis, association analyses and multivariable analysis. A synergism analysis between vaccination status and symptomatology during the waves was performed. RESULTS: Females were found at a higher risk of developing symptoms. Four SARS-CoV-2 waves were identified. Pharyngitis and rhinitis were more frequent during the fourth wave and among vaccinated subjects while cough, fever, flu syndrome, headache, anosmia, ageusia, arthralgia/arthritis and myalgia were more frequent during the first three waves and among unvaccinated subjects. A correlation was found between vaccination and the different waves in terms of developing pharyngitis and rhinitis. CONCLUSION: Vaccination status and viruses' mutations had a synergic effect in the mitigation of the symptomatology caused by SARS-CoV-2 in healthcare workers.

The Relationship between Working Night Shifts and Depression among Nurses: A Systematic Review and Meta-Analysis.

BACKGROUND: For many years, occupational physicians have debated whether there is a link between working the night shift and depression and other co-occurring mental health issues, with an emphasis on work-related, biological, individual, and environmental factors. We performed this systematic review and meta-analysis to estimate the overall association between sleep deprivation and depression among nurses working night shifts. METHODS: A systematic search was carried out across the electronic databases PubMed, Scopus, and Web of Science from inception to 30 September 2022, for studies that reported a relationship between estimated night shift work and depression in nurses. The outcomes were measured using the odds ratio (OR) and matching 95% confidence interval (CI). The I2 statistic was used to assess heterogeneity. The Grading of Recommendations Assessment, Development and Evaluation technique was used to evaluate the quality of the evidence, and the Newcastle-Ottawa Scale was utilized to assess the methodological quality of each of the included studies. We determined the overall relationship between working nights and the onset of depression. RESULTS: A total of 20 studies were included in the systematic review. Furthermore, 8 studies were included in the meta-analysis due to their common use of the OR as an effect measure. The 8 studies gave an overall estimate indicating a statistically significant association between night shift work and depression among nurses (OR = 1.49 95% CI: 1.26, 1.76). The prediction interval for the overall estimate was (0.995, 2.231). This implies that the true OR in a future study would most likely fall within this range, with a 95% certainty. CONCLUSIONS: The outcome of this systematic review and meta-analysis showed a significant association between night shift work, the circadian and sleep disruption it causes, and the risk of depression in nurses. This demonstrates that nurses who work night shifts are at risk of developing depression.

The effects of bullying on healthcare workers: an umbrella review of systematic reviews and meta-analyses.

OBJECTIVE: This umbrella review will provide a broad overview of the prevalence of vertical and horizontal bullying, the departments and the workers most affected by these attacks. METHODS: We included systematic reviews and meta-analyses examining the effects of bullying on healthcare workers. Data extraction and analysis was performed on all included studies. The research strategy was undertaken in May 2021 and included three electronic databases (PubMed, Scopus and Web of Science): a total of 435 articles were retrieved from the Abstract and, once duplicates and irrelevant articles were removed, a total of 19 useful articles were reviewed. A comprehensive search was done to retrieve articles based on a PRISMA compliant protocol registered in PROSPERO: CRD 42021268082. RESULTS AND DISCUSSION: The general prevalence goes from 2 to 100%; for the individual healthcare workers, the highest prevalence is among nurses, 9-100%, followed by doctors 11.50-78.10%. Due to the heterogeneity of the studies, the other healthcare workers such as midwives, radiology technicians, administrative, employees were grouped and their prevalence goes from 3.30 to 100%. The results show that female nurses are significantly more likely to be abused than their male colleagues (women 3.60-100%; men 2.00-64.40%). The workplace in many studies was relevant for bullying: in particular, the most affected departments were emergency departments (2-100%) followed by intensive care units (17-84.80%). CONCLUSIONS: Bullying is extremely present among health workers and must be adequately countered. It will be necessary to carry out further studies to deepen the knowledge on this matter.

Analysis of Knowledge, Attitudes and Behaviours of Health Care Workers towards Vaccine-Preventable Diseases and Recommended Vaccinations: An Observational Study in a Teaching Hospital.

Background: Recommended vaccinations are the cheapest and most effective measure to reduce the risk of transmission and related complications, especially in high-risk healthcare settings. This study aimed to evaluate the knowledge, attitudes and behaviours of HCWs in relation to national recommendations. Methods: A transversal study was conducted through administration of a questionnaire by personal interview. The following care units were involved: Paediatric, Neonatal, Cardiac Surgery and General Intensive Care Units and Infectious Diseases Unit. Results: The study sample comprised 308 HCWs. Half the sample were aware of the vaccination recommendations, with occupation and age found to be predictive factors (OR = 9.38, 95%CI: 2.07−42.41; OR = 0.36, 95%CI: 0.22−0.60). A higher percentage defined the diseases as a risk for their patients' health, although this perception was lower in the over-40 age group. In several cases, there were statistically significant differences between the care units (p < 0.001). Around three-quarters of the sample agreed that vaccination should be mandatory; willingness to undergo a future booster vaccination was statistically correlated with the variables of age and care unit (p < 0.001, p = 0.03). Conclusion: The protection of health in the workplace can be achieved through some strategic actions, such as the implementation of educational strategies, and protocols for the monitoring of immunocompetence and the improvement of vaccination.

Prevalence of SARS-CoV-2 infection and associated risk factors: A testing program and nested case-control study conducted at Sapienza University of Rome between March and June 2021.

Background: To safely resume in-person activities during the COVID-19 pandemic, Sapienza University of Rome implemented rigorous infection prevention and control measures, a successful communication campaign and a free SARS-CoV-2 testing program. In this study, we describe the University's experience in carrying out such a program in the context of the COVID-19 response and identify risk factors for infection. Methods: Having identified resources, space, supplies and staff, from March to June 2021 Sapienza offered to all its enrollees a molecular test service (8.30 AM to 4 PM, Monday to Thursday). A test-negative case-control study was conducted within the program. Participants underwent structured interviews that investigated activity-related exposures in the 2 weeks before testing. Multivariable conditional logistic regression analyses were performed. Adjusted odds ratios (aORs) and 95% confidence intervals (95% CIs) were calculated. Results: A total of 8,959 tests were administered, of which 56 were positive. The detection trend followed regional tendencies. Among 40 cases and 80 controls, multivariable analysis showed that a known exposure to a COVID-19 case increased the likelihood of infection (aOR: 8.39, 95% CI: 2.38-29.54), while having a job decreased it (aOR: 0.23, 95% CI: 0.06-0.88). Of factors that almost reached statistical significance, participation in activities in the university tended to reduce the risk (aOR: 0.32, 95% CI: 0.09-1.06), while attendance at private gatherings showed an increasing risk trend (aOR: 3.48, 95% CI: 0.95-12.79). Age, gender, activities in the community, visiting bars or restaurants, and use of public transportation were not relevant risk factors. When those students regularly attending the university campus were excluded from the analysis, the results were comparable, except that attending activities in the community came close to having a statistically significant effect (aOR: 8.13, 95% CI: 0.91-72.84). Conclusions: The testing program helped create a safe university environment. Furthermore, promoting preventive behavior and implementing rigorous measures in public places, as was the case in the university setting, contributed to limit the virus transmission.

Susceptibility towards Chickenpox, Measles and Rubella among Healthcare Workers at a Teaching Hospital in Rome.

Immunization is the best protection against chickenpox, measles and rubella. It is important to identify and immunize susceptible healthcare workers to prevent and control hospital infections. Our aim was to estimate the susceptibility level of healthcare workers at a Teaching Hospital in Rome concerning these diseases and the factors associated to the susceptibility. Methods: a cross sectional study was carried out at the Department of Occupational Medicine of the Umberto I General Hospital of Rome. Participants were recruited during routine occupational health surveillance. As far as inclusion criteria, the following professionals were considered: doctors, nurses, laboratory technicians and other health professionals. Concerning the exclusion criteria, patients with HIV, cancer and diseases of the immune system, and acute illness or fever more than 38.5 °C, were not included in the study. A blood sample was tested for the presence of antibodies against measles, rubella and chicken pox. Results: 1106 healthcare professionals were involved in the study (41.8% nurses, 30.4% doctors, 12.3% laboratory technicians, 15.1% other health professionals): 25 (2.3%), 73 (6.6%) and 35 (3.2%) of these were susceptible to measles, rubella and chicken pox, respectively. The only variable associated with susceptibility of measles was age (p < 0.001). Furthermore, there was evidence of an association between various susceptibilities, particularly between measles and chickenpox (OR: 4.38). Conclusion: this study showed that even if the majority of our healthcare professionals are immunized for MRV, it is necessary not to underestimate the seronegativity of non-immune ones. All health professionals should be vaccinated to ensure safety for patients, especially the weakest.

Flu Vaccination among Healthcare Professionals in Times of COVID-19: Knowledge, Attitudes, and Behavior.

The seasonal flu vaccine is the most important way to prevent influenza epidemics, so it is useful to increase the awareness of health professionals. The aim of our study is to evaluate knowledge, attitudes, and behavior about flu vaccination among healthcare professionals in times of COVID-19. METHODS: A cross sectional study was carried out between November 2020 and April 2021. Participants were recruited in teaching hospital 'Policlinico Umberto I' of Rome. A survey of 24 questions about flu vaccination was administered, evaluating their knowledge, attitude, and practice about this topic. RESULTS: 872 healthcare professionals were involved in the study (36.9% men, 63.1% women). More than 90% of the HCWs, especially physicians, recognize the importance of getting influenza vaccination: The main reasons for not getting vaccinated were fear of vaccine side effects (20.3%) and fear of the needle (6.4%). Nevertheless, 40.7% of the healthcare providers consider mandatory vaccination as unethical, especially if they work in low-intensity wards. CONCLUSION: a high percentage of healthcare workers agree with the importance of influenza vaccination and only a small percentage is still opposed. It is therefore important to continue to promote the influenza vaccination through communication and health education programs.

Prevalence and Risk Factors of Bullying and Sexual and Racial Harassment in Healthcare Workers: A Cross-Sectional Study in Italy.

BACKGROUND: This cross-sectional study aims to evaluate the prevalence and socio-demographic factors associated with workplace bullying, sexual harassment and racial harassment among Italian health workers. METHODS: We recruited 3129 participants using an online Italian translation of the 'Workplace Violence in the Health Sector Country Case Studies Research Instruments Survey' (WVHS) questionnaire. Data were analyzed with univariate (chi-square) and multivariate (multiple logistic regression) analysis. RESULTS: Univariate analysis shows that females are significantly more affected by bullying (16.4% vs. 12.3%) and sexual harassment (2.4% vs. 1.3%). On the other hand, males are significantly more affected by racial harassment (3.1% vs. 2.0%). Multivariate analysis shows higher odds of being affected by bullying (OR = 1.30; 95% CI (1.03, 1.64)) and sexual harassment (OR = 2.08; 95% CI (1.04, 4.00)) for females, and higher odds of undergoing racial harassment (OR = 1.55; 95% CI (0.95, 2.53)) for males. CONCLUSION: This analysis of work situations looks to identify those risk factors, existing or potential, that increase the probability of episodes of violence. A group of work or other subjects identified by direction will have to evaluate the vulnerability of workplaces and establish more effective preventive actions to be adopted.

Assessment of the Impact of COVID-19 Lockdown on the Nutritional Status and Lipid Profile of Employees in a Teaching Hospital in Rome: A Retrospective Cohort Study.

Background: on the 9 March 2020, the Italian government declared a state of lockdown on the entire national territory aimed at reducing the spread of SARS-CoV-2, causing strong repercussions for people's lifestyles. The aim of the study was to analyze the impact of the lockdown on the nutritional status and lipid profile of employees of an Italian teaching hospital. Methods: an observational retrospective cohort study was carried out at the Department of Occupational Medicine of the Umberto I General Hospital of Rome, including all employees who underwent two consecutive occupational medical examinations before and after the first lockdown (9 March 2020−18 May 2020). Employee medical records were used as a data source. Results: 1014 employees were involved in the study (50.6% nurses, 31% physicians, 14.8% technical staff, 3.6% administrative staff). Post lockdown BMI, total cholesterol and LDL values increased statistically significantly compared to pre lockdown ones. Nurses showed a significant association with increased BMI (p < 0.001), while workers with heart disease were inversely associated with total cholesterol (p < 0.001) and LDL (p < 0.001). Conclusion: this study showed that lockdown had a significant impact on employees' lifestyles. Further studies are needed to understand changes in health-related behaviors, such as diet and physical activity, of specific categories of workers over time under lockdown conditions.
