Primary cell cultures for the personalized therapy in aggressive thyroid cancer of follicular origin.

Thyroid cancer (TC) is the most prevalent endocrine malignancy. More than 90 % of TC is represented by differentiated TC (DTC) arising from the follicular thyroid cells. DTC includes papillary TC (PTC), follicular TC (FTC), and Hürthle cell TC. Anaplastic TC (ATC) accounts for 1% of TC, and it represents 15-40 % of TC death. Current treatment strategies are not completely effective against aggressive DTC or ATC, and mortality is one of the most important challenges. Recently, progresses have been obtained in the understanding of the molecular/genetic basis of TC progression, and new drugs have been introduced [i.e. tyrosine kinase inhibitors (TKIs)], able to block the oncogenic or signaling kinases, associated with cellular growth. Thyroid cell lines, obtained from tumoral cells and chosen for high proliferation in vitro, have been used as preclinical models. Actually, these cells lose the characteristic features of the primary tumor, because they adapt to in vitro growth conditions. For these reasons, the use of these cell lines has important limitations, and more recently human primary cell cultures have been established as monolayer cultures, and investigated for their biological behavior. Moreover, in the past, primary TC cells could be collected only through surgical biopsies, while recently human primary cell cultures can be established also from samples of fine-needle aspiration citology from aggressive dedifferentiated DTC or ATC. Testing in vitro different TKIs in each patient can help to develop new personalized treatments, without using ineffective drugs. In conclusion, personalized medicine and precise oncology, which consider both patients and their disease features, represent the future of the treatment approach, and further progress is needed in this direction.

Heart rate variability, serum cortisol levels and temperament in a sample of workers exposed to occupational stress: a preliminary report.

Work-related stress is an emerging risk for psychiatric occupational disorders including Adjustment Disorders (AD). The aim of this study was to investigate in workers exposed to occupational stress suffering from AD about putative indices of stress and mental health resilience such as serum cortisol (seC) levels, Heart Rate Variability (HRV) and affective temperaments. We consecutively recruited 15 male and 15 female AD patients between workers evaluated for occupational stress at an Italian Occupational Medicine Unit. SeC levels were measured by specific immunoassay. HRV indices were recorded using Task Force® Monitor system (CNSystems, Graz, Austria). Specific questionnaires were used to measure perceived and occupational stress, psychopathological symptoms and temperament. Women presented higher levels of occupational stress, higher High-Frequency HRV (HF-HRV) and lower Low-Frequency HRV (LF-HRV) than men. SeC levels were positively correlated with LF-HRV values and negatively with HF-HRV values. The LF/HF ratio resulted to be inversely correlated with the score of Harm Avoidance temperament dimension and directly with the score of Reward Dependence temperament dimension. In conclusion, in AD patients exposed to occupational stress high seC levels and reward dependence appear to be associated with a pattern of HRV reflecting less mental health resilience.

Diversity & Inclusion: Fitness for Work Through a Personalized Work Plan For Workers With Disabilities and Chronic Diseases According to the Iso 30415/2021.

The recent standard ISO 30415-2021 - Human resources management - Diversity and inclusion -  was developed internationally within the technical committee ISO/TC 260 "Human resources management" (Working group WG 8 "Diversity and inclusion") and underlines the need for actions to create a work environment that is inclusive of diversity (e.g. in terms of health, gender, age, ethnicity, culture). Developing an inclusive work environment requires ongoing commitment and input from the entire organization regarding policies, processes, organizational practices, and individual behavior. As far as the role of occupational medicine is concerned, this direction can be supported by the correct management of disabled workers and workers with chronic pathologies that affect their fitness for duty. The "reasonable accommodation" is the way by which the European Union first, and the United Nations then intended to support the inclusion of disabled people in the world of work. The Personalized Work Plan includes different approaches (organizational, technical, procedural) meant for modifying the work activity envisaged for the disabled worker or for any worker suffering from chronic diseases or dysfunctions. The adoption of the Personalized Work Plan implies the effort of redesigning the workstation, the work procedures, or even the planning of different micro and macro tasks etc., in order to prioritize the adaptation of the working environment to the worker, safeguarding the value of the worker's productivity according to the principle of reasonable accommodation.

Combination Strategies Involving Immune Checkpoint Inhibitors and Tyrosine Kinase or BRAF Inhibitors in Aggressive Thyroid Cancer.

Thyroid cancer is the most common (~90%) type of endocrine-system tumor, accounting for 70% of the deaths from endocrine cancers. In the last years, the high-throughput genomics has been able to identify pathways/molecular targets involved in survival and tumor progression. Targeted therapy and immunotherapy individually have many limitations. Regarding the first one, although it greatly reduces the size of the cancer, clinical responses are generally transient and often lead to cancer relapse after initial treatment. For the second one, although it induces longer-lasting responses in cancer patients than targeted therapy, its response rate is lower. The individual limitations of these two different types of therapies can be overcome by combining them. Here, we discuss MAPK pathway inhibitors, i.e., BRAF and MEK inhibitors, combined with checkpoint inhibitors targeting PD-1, PD-L1, and CTLA-4. Several mutations make tumors resistant to treatments. Therefore, more studies are needed to investigate the patient's individual tumor mutation burden in order to overcome the problem of resistance to therapy and to develop new combination therapies.

Covid-19 vaccine management (Comirnaty and mrna-1273 Moderna) in a teaching hospital in Italy: a short report on the vaccination campaign.

OBJECTIVES: In this article, we aim to share our experience in the hospital reorganization made to conduct the SARS-CoV-2 vaccination campaign, based on the principles of flexibility and adaptability. STUDY DESIGN: A descriptive study. METHODS: The data concerning the organization of the vaccination campaign were taken from the operative protocol developed by the hospital dedicated task force, composed by experts in hygiene, public health, occupational medicine, pharmacists, nurses, hospital quality, and disaster managers. Data about the numbers of vaccine administered daily were collected by the Innovation and Development Operative Unit database. RESULTS: Vaccinations against COVID-19 started across the EU on the 27th of December 2020. The first phase of the vaccination campaign carried out in our hospital was directed to healthcare workers immunization including medical residents, social care operators, administrative staff and technicians, students of medicine, and health professions trainees. The second phase was enlarged to the coverage of extremely fragile subjects. Thanks to the massive employment of healthcare workers and the establishment of dynamic pathways, it was possible to achieve short turnaround times and a large number of doses administered daily, with peaks of 870 vaccines per day. From the 27th of December up to the 14th of March a total of 26,341 doses of Pfizer have been administered. 13,584 were first doses and 12,757 were second doses. From the 4th to the 14th of March, 296 first doses of Moderna were dispensed. It was necessary to implement adequate spaces and areas adopting anti-contagion safety measures: waiting area for subjects to be vaccinated, working rooms for the dilution of the vaccine and the storage of the material, vaccination rooms, post-vaccination observation areas, room for observation, and treatment of any adverse reactions, with an emergency cart available in each working area. CONCLUSIONS: The teaching hospital of Pisa faced the beginning of the immunization campaign readjusting its spaces, planning an adequate hospital vaccination area and providing an organization plan to ensure the achievement of the targets of the campaign. This represented a challenge due to limited vaccine doses supplied and the multisectoral teams of professionals to coordinate in the shortest time and the safest way possible. The organizational model adopted proved to be adequate and therefore exploited also for the second phase aimed to extremely fragile subjects.

[The protection of the worker affected by neoplastic pathologies and the role of the occupational physician for his reintegration into work]. / Le tutele del lavoratore con patologie oncologiche e il ruolo del medico competente per il suo reinserimento lavorativo.

OBJECTIVES: The protection of the worker affected by neoplastic pathologies and his reintegration into work represent subjects of undoubted relevance for the occupational physician. Many are the workers affected by neoplastic diseases and more are those who are able to regain good living conditions and sufficient work capacity to be reintegrated into profitable work. Several rights are related to the assessment of a certain percentage of disability, the recognition of "Handicap in a serious situation", and others according to the requirements of the Italian law for the right to work of disabled people -L. 68/99 s.m.i.-. METHODS: The Occupational Physician manages the oncology patient through the targeted placement ex L. 68/99 s.m.i. or, more often, during the activity of health surveillance has to assess whether the job, considering the risks connected to it, is compatible with the conditions of biological validity of the worker, identifying, possibly, prescriptions or limitations. RESULTS: In our experience, customized working plan is an operational methodology that has proved to be very useful. In practice, the Occupational Physician uses a method to help the back to work of the worker with disability, formalizing before the limits to the performance of the work activity. The assessment of fitness for work is related to a work plan presented by the employer, based on the indications of the occupational physician, based on disability (health conditions / worker's susceptibility) that modulates or avoids job tasks that could prove harmful or aggravating the health condition of the employee. Teleworking and smart working can also be considered among the possible protection measures. CONCLUSIONS: Finally, it is useful to recall the role of INAIL for workers with a recognized neoplastic pathology related to work. With the Italian law 190/2014 art. 1, paragraph 166 are assigned to the INAIL the skills relating to the reintegration and work integration of people with disabilities from work with expenses for the INAIL. There are therefore a number of reference measures by the INAIL and the types of interventions for reintegration are identified..

Myo-inositol in autoimmune thyroiditis, and hypothyroidism.

Myo-inositol (Myo-Ins) plays an important role in thyroid function and autoimmunity. Myo-Ins is the precursor for the synthesis of phosphoinositides, which takes part in the phosphatidylinositol (PtdIns) signal transduction pathway, and plays a decisive role in several cellular processes. In the thyroid cells, PtdIns is involved in the intracellular thyroid-stimulating hormone (TSH) signaling, via Phosphatidylinositol (3,4,5)-trisphosphate (PtdIns(3,4,5)P3) (PIP-3). Moreover, the phosphatidyl inositol 3 kinases (PI3K) family of lipid kinases regulates diverse aspects of T, B, and Tregs lymphocyte behaviour. Different mouse models deficient for the molecules involved in the PIP3 pathway suggest that impairment of PIP3 signaling leads to dysregulation of immune responses and, sometimes, autoimmunity. Studies have shown that cytokines modulate Myo-Ins in thyroid cells. Moreover, clinical studies have shown that after treatment with Myo-inositol plus seleniomethionine (Myo-Ins + Se), TSH levels significantly declined in patients with subclinical hypothyroidism due to autoimmune thyroiditis. The treatment was accompanied by a decline of antithyroid autoantibodies. After treatment serum CXCL10 levels declined, confirming the immune-modulatory effect of Myo-Ins. Additional research is necessary in larger population to evaluate the effect on the quality of life, and to study the mechanism of the effect on chemokines.

Fitness for work in employeers exposed to ionizing radiations with an increased susceptibility to malignancies. / Giudizio di idoneità in laoratori radioesposti ipersuscettibili allo sviluppo di neoplasia.

BACKGROUND: The assessment of fitness for work regarding employees exposed to ionizing radiations and with an increased susceptibility to malignancies requires a particularly complex procedure. OBJECTIVES: To determine, where possible, parameters for the assessment of fitness for work of employees exposed to ionizing radiations, who have increased susceptibility to malignancies. METHODS: To set out suitable criteria for the assessment of fitness for work. RESULTS: Existing laws, technical standards, scientific literature and publications issued by international organizations and dealing with the health and safety of workers exposed to radiations may help establish criteria to inform assessment of fitness for work. CONCLUSIONS: Taking into account the concept of acceptable risk, the application of objective criteria as well as of subjective considerations may allow professionals to make individualised assessments of fitness for work.

Genome-wide identification of replication fork stalling/pausing sites and the interplay between RNA Pol II transcription and DNA replication progression.

BACKGROUND: DNA replication progression can be affected by the presence of physical barriers like the RNA polymerases, leading to replication stress and DNA damage. Nonetheless, we do not know how transcription influences overall DNA replication progression. RESULTS: To characterize sites where DNA replication forks stall and pause, we establish a genome-wide approach to identify them. This approach uses multiple timepoints during S-phase to identify replication fork/stalling hotspots as replication progresses through the genome. These sites are typically associated with increased DNA damage, overlapped with fragile sites and with breakpoints of rearrangements identified in cancers but do not overlap with replication origins. Overlaying these sites with a genome-wide analysis of RNA polymerase II transcription, we find that replication fork stalling/pausing sites inside genes are directly related to transcription progression and activity. Indeed, we find that slowing down transcription elongation slows down directly replication progression through genes. This indicates that transcription and replication can coexist over the same regions. Importantly, rearrangements found in cancers overlapping transcription-replication collision sites are detected in non-transformed cells and increase following treatment with ATM and ATR inhibitors. At the same time, we find instances where transcription activity favors replication progression because it reduces histone density. CONCLUSIONS: Altogether, our findings highlight how transcription and replication overlap during S-phase, with both positive and negative consequences for replication fork progression and genome stability by the coexistence of these two processes.

Cardiac Substrate Utilization and Relationship to Invasive Exercise Hemodynamic Parameters in HFpEF.

The authors conducted transcardiac blood sampling in healthy subjects and subjects with heart failure with preserved ejection fraction (HFpEF) to compare cardiac metabolite and lipid substrate use. We demonstrate that fatty acids are less used by HFpEF hearts and that lipid extraction is influenced by hemodynamic factors including pulmonary pressures and cardiac index. The release of many products of protein catabolism is apparent in HFpEF compared to healthy myocardium. In subgroup analyses, differences in energy substrate use between female and male hearts were identified.

Evaluation of Smallpox Vaccination Coverage and Attitude towards Monkeypox Vaccination among Healthcare Workers in an Italian University Hospital.

(1) Background: In 2022, monkeypox (Mpox) was declared a public health emergency. The European Medicines Agency has authorized the use of Imvanex/Jynneos, a smallpox vaccine, for coverage against pox. Healthcare workers (HCWs) are all considered by the European Centre for Disease Prevention and Control to be at risk, but in Italy, vaccination was offered only to laboratory personnel. The present study aims to investigate smallpox vaccination coverage (VC) that provides protection against Mpox among HCWs in an Italian university hospital and to assess HCWs' attitudes towards the possibility of getting vaccinated against Mpox. (2) Methods: We conducted a cross-sectional survey. 336 HCWs from selected wards were asked to fill out a self-declaration to collect their sex, profession, ward, vaccination status, and attitude toward Mpox vaccination. (3) Results: 60.71% of HCWs involved provided the requested data; 38.7% of them were previously vaccinated against smallpox, which corresponds to 23.5% of the total HCWs in the wards considered. Considering those born before 1979 as vaccinated, VC increases from 23.5% to 41.7%; the percentage of HCWs who adhered to vaccination is 23%; laboratory technicians showed a lower willingness to be vaccinated. The ward with the highest willingness to vaccinate is proctological surgery. (4) Conclusions: Based on our experience, a variability in smallpox VC and in willingness to vaccination has emerged both among different job titles and age categories and across the wards analyzed. Additionally, our survey reveals that vaccination attitudes are higher among HCWs from wards that currently do not have free access to such vaccinations.

Comparison between Standard Expository Cognitive Behavioral Therapy (CBT-E) and Immersive Virtual Reality CBT (CBT-VR) for Rehabilitation of Patients Affected by Occupational Stress Disorders: Study Protocol.

Work-related stress presents a significant impact on work performance and physical health. It has been associated with the onset of a multitude of symptoms that can lead to occupational stress diseases, namely Adjustment Disorder and Post-Traumatic Stress Disorder. The literature has evidenced that "exposure therapy" of cognitive-behavioral training (CBT-E) seems to be the most effective technique to manage stress symptoms, including work stress diseases, and several studies have considered Virtual Reality (VR) as an adjuvant tool to exposure-based psychotherapy (CBT-VR) for the treatment of multiple psychiatric disorders. The aim of this study is to evaluate the effectiveness of CBT with exposure to stressful work scenarios in imaginative (CBT-E) and in immersive virtual reality (CBT-VR) scenarios in a group of workers affected by work-related stress disorders and compare the clinical and physiological outcomes between the two exposure techniques. A long-term goal would be to develop an evidence-based rehabilitation program as a treatment for the reintegration into work of patients affected by these psychiatric disorders.

Effects of altered cellular ultrastructure on energy metabolism in diabetic cardiomyopathy: an in silico study.

Diabetic cardiomyopathy is a leading cause of heart failure in diabetes. At the cellular level, diabetic cardiomyopathy leads to altered mitochondrial energy metabolism and cardiomyocyte ultrastructure. We combined electron microscopy (EM) and computational modelling to understand the impact of diabetes-induced ultrastructural changes on cardiac bioenergetics. We collected transverse micrographs of multiple control and type I diabetic rat cardiomyocytes using EM. Micrographs were converted to finite-element meshes, and bioenergetics was simulated over them using a biophysical model. The simulations also incorporated depressed mitochondrial capacity for oxidative phosphorylation (OXPHOS) and creatine kinase (CK) reactions to simulate diabetes-induced mitochondrial dysfunction. Analysis of micrographs revealed a 14% decline in mitochondrial area fraction in diabetic cardiomyocytes, and an irregular arrangement of mitochondria and myofibrils. Simulations predicted that this irregular arrangement, coupled with the depressed activity of mitochondrial CK enzymes, leads to large spatial variation in adenosine diphosphate (ADP)/adenosine triphosphate (ATP) ratio profile of diabetic cardiomyocytes. However, when spatially averaged, myofibrillar ADP/ATP ratios of a cardiomyocyte do not change with diabetes. Instead, average concentration of inorganic phosphate rises by 40% owing to lower mitochondrial area fraction and dysfunction in OXPHOS. These simulations indicate that a disorganized cellular ultrastructure negatively impacts metabolite transport in diabetic cardiomyopathy. This article is part of the theme issue 'The cardiomyocyte: new revelations on the interplay between architecture and function in growth, health, and disease'.

A Medical Resident with a History of Alcohol Abuse and Suicidal Ideation: A Challenge for Both Psychiatry and Occupational Medicine in the Context of the First Wave of the COVID-19 Pandemic.

This case study draws attention to the hazards of physicians with a history of alcohol addiction and a particular psychopathology framework in the context of occupational health surveillance, particularly during the challenging working conditions brought about by the COVID-19 pandemic. The case involves a hospital resident in her thirties, with a previous history of addiction and attempts at suicide, who was assigned to a COVID-19 unit of an Italian hospital. In this case study, we discuss the preventive intervention put in place in order to protect physicians' health and work. What emerges is the key role that rapid substantive communications between specialists play in formulating an effective strategy for dealing with these conditions. We believe this case is noteworthy for the lessons that can be learned for tailoring prevention and treatment pathways for health care workers with addiction.

Do Autistic Traits Correlate with Post-Traumatic Stress and Mood Spectrum Symptoms among Workers Complaining of Occupational Stress?

The adult autism subthreshold spectrum model appears to be a useful tool for detecting possible vulnerability factors in order to develop mental disorders in the contest of work-related stress. The aim of the present study is to analyze the relationship between autism, mood, and post-traumatic spectrum in a cohort of subjects complaining of work-related stress before the COVID-19 pandemic. The authors carried out a retrospective investigation of both medical records and self-assessment tools of a sample of subjects evaluated at the Occupational Health Department of a University hospital in central Italy. Data showed significant correlations between the AdAS spectrum, TALS-SR, and MOODS total and domain scores. A multiple linear regression evidenced that both the AdAS spectrum and TAL-SR significantly predict the MOODS scores. In particular, mediation analysis showed both a direct and indirect, mediated by TALS-SR, effect of the AdAS Spectrum on the MOODS-SR. These results corroborate the role of autistic traits in influencing the traumatic impact of work-related stress and the development of mood spectrum symptoms.

Affective temperament and mood spectrum symptoms in workers suffering from work-related stress disorders.

INTRODUCTION: Adjustment Disorders (AD) which develop in response to work-related stressors represent a model of psychiatric occupational disease. Major Depressive Episodes (MDE) although often associated to work-related stressors are unlikely recognized by insurance institutes as occupational diseases. Affective temperament and mood spectrum symptoms are possible factors of vulnerability to stress. The aim of this study was to investigate if temperaments and mood spectrum symptoms had a different distribution among workers exposed to occupational stress and suffering from different psychiatric disorders (AD, MDE). METHODS: 156 AD and 97 MDE patients were recruited and evaluated with scales for perceived stress (PSM) and work-related stress (JCQ), for psychopathological symptoms (BDI-II, SAS), for affective temperament (TEMPS-A[P]) and for lifetime mood spectrum symptoms (MOODS-SR). Group comparisons and correlation analyses between variables were performed by parametric or non-parametric statistical tests according to variables distribution. RESULTS: The diagnostic groups did not differ for perceived and occupational stress levels. MDE patients reported significantly higher BDI-II score and MOODS-SR scores than AD ones. The hyperthymic temperament was significantly more frequent in AD than in MDE group. The hyperthymic score, differently from other dimensions of temperament and from mood spectrum components, negatively correlated or did not correlate with psychopathological symptoms severity and perceived stress levels. LIMITATIONS: Predictive limitation because of cross-sectional design. CONCLUSIONS: The hyperthymic temperament as opposed to lifetime subtreshold mood symptoms appears to be more represented in patients suffering from occupational AD than in MDE ones. Acknowledging vulnerability factors to job stress could support clinicians in occupational diseases prevention and management.

Evaluation of the Anti-Spike (RDB) IgG Titer among Workers Employed at the University of Pisa Vaccinated with Different Types of SARS-CoV-2 Vaccines.

With the development of SARS-CoV-2 vaccines, many authors started evaluating the immunization efficacy of the available vaccines mainly through sero-positivity tests or by a quantitative assessment of the IgG against the spike protein of SARS-CoV-2 virus in vaccinated subjects. In this work, we compared the titers resulting from vaccination and tried to understand the potential factors affecting the immune response to the available SARS-CoV-2 vaccines. This study was conducted on 670 volunteers employed at the University of Pisa and undergoing a health surveillance program at the University Hospital of Pisa. For each participant, 10 mL of blood, information about contacts with confirmed cases of COVID-19, age, sex, SARS-CoV-2 vaccination status, previous SARS-CoV-2 infection and symptoms, type of vaccine and the date of administration were collected. In the multivariate analysis, the type of vaccine, the presence of symptoms in SARS-CoV-2 positive individuals, and the distance from the second dose significantly affected the antibody titer; the combined vaccination resulted in a faster decay over time compared with the other types of vaccination. No significant differences were observed between Spikevax and Comirnaty (p > 0.05), while the antibody levels remain more stable in subjects undergoing Vaxzevria vaccination (p < 0.01) compared with mRNA-based ones.

Hyperthermic Intrathoracic Chemotherapy for Malignant Pleural Mesothelioma: The Forefront of Surgery-Based Multimodality Treatment.

INTRODUCTION: Malignant Pleural Mesothelioma (MPM) is characterized by an aggressive behavior and an inevitably fatal prognosis, whose treatment is still far from being standardized. The role of surgery is questionable since a radical resection is unattainable in most cases. Hyperthermic IntraTHOracic Chemotherapy (HITHOC) combines the advantages of antitumoral effects together with those of high temperature on the exposed tissues with the aim to improve surgical radicality. MATERIAL AND METHODS: this is a narrative review on the role of HITHOC in the management of MPM patients. To provide data on the beginnings and the historical evolution of this technique, we searched the available literature by selecting the more exhaustive papers on this topic. RESULTS: from 1994 to date different authors experimented HITHOC following a cytoreductive surgery in MPM, obtaining in most cases a good local control and a better overall survival associated to very low complication rate. CONCLUSIONS: HITHOC may be considered as a safe, feasible and effective procedure although there is a high heterogeneity between different protocols adopted worldwide. More structured studies are needed to reach a unanimous consensus on this technique.

Antimeningococcal Vaccination Coverage Among Healthcare Workers in an Italian University Hospital.

Introduction: Following an outbreak of meningococcal epidemic in 2015 and 2016 in Tuscany, we registered a higher demand for antimeningococcal vaccination (anti-Men ACWY) by Healthcare Workers of the University Hospital of Pisa [Azienda Ospedaliero Universitaria Pisana (AOUP)]. The purpose of this work is to analyze and discuss data on vaccination coverage resulting from this vaccination campaign. Materials and Methods: We conducted a monocentric study about anti-Men vaccination in the healthcare workers of the AOUP following the outbreak of meningococcal meningitis that occurred mainly in the population of the Tuscan provinces of Pisa, Pistoia, Prato, and Florence. The variables under examination were age, sex, educational qualification, and job profile. Department healthcare workers were vaccinated with two types of conjugated tetravalent vaccines for the A, C, Y, and W135 strains. Data were analyzed using the SPSS software. Results: The total population of the workers in AOUP was 7,188 subjects; the population considered in the study was 5,889. Between 2015 and 2017, a total of 2,423 subjects (41.1%) underwent anti-Men vaccination. Women, older HCWs, those with a lower educational qualification, doctors, and the HCWs of the maternal and child department, and imaging department recorded a statistically significant better vaccine compliance. Discussion: The AOUP, implementing the program of the Tuscany Region of vaccination against Neisseria meningitidis, has contributed to reduce the incidence of invasive meningococcal disease. Some critical issues remain in the compliance of some sections of the population, despite the high level of adherence recorded in this case, probably also due to the great media coverage of the event.

Irritable Bowel Syndrome prevalence and work ability in a sample of healthcare workers exposed to occupational stress.

OBJECTIVE: Occupational stress represents a significant precipitating factor in different diseases but its role in Irritable Bowel Syndrome (IBS) needs to be clarified. The present cross-sectional study aimed at investigating the prevalence of IBS diagnosis in a sample of health workers and exploring the potential relationships between IBS, work-related stress levels and work ability. METHODS: 653 health workers undergoing periodical occupational health surveillance at the Occupational and Preventive Medicine Unit of a major University Hospital in central Italy, were consecutively recruited and screened for IBS diagnosis, according to ROMA IV criteria. The rating scales IBS Severity Scoring System (IBS-SSS), Demand-Control-Support Questionnaire (DCSQ) and Work Ability Index (WAI) were used to assess respectively IBS severity, occupational stress and work ability levels. RESULTS: IBS prevalence in the sample was 16.8%. Participants suffering from IBS were characterized by a higher prevalence of psychiatric diagnosis and sleep disturbances, higher levels of job strain and isostrain as well as by lower levels of work ability compared to non affected subjects. Moreover, the severity of IBS correlated positively with occupational stress and both were negatively associated with work ability. CONCLUSIONS: The present results suggest the need for preventive, organizational and management strategies at workplace aimed at protecting the health and well-being but also productivity of the worker with IBS.
