The study aims to evaluate the performance of selected, high-volume, highly specialized, Italian Breast Centers at the time of COVID-19 pandemic (year 2020), compared to pre-pandemic time (year 2019), highlighting differences in terms of clinical presentation of breast cancer (BC) and therapeutic strategies.Patients' data were provided by the Senonetwork data warehouse Senonet. In order to examine changes in the surgical and oncological management of BC patients during different phases of COVID-19 pandemic, we took advantage of a selection quality indicators (QIs). We performed the analyses in two time-frames, from July to September (Jul-Sep) (2019 versus 2020) and from October to December (Oct-Dec) (2019 versus 2020).Our analysis did not show any statistically significant difference in terms of diagnosis, surgical, oncological and radiation therapy procedures between the two trimesters 2019 and 2020. Nevertheless, we observed statistically significant differences, favoring 2020, when analyzing time-to surgery and time-to radiotherapy. On the other hand, we observed a significant reduction of neoadjuvant chemotherapy and we did not recollect any data on a major use of neoadjuvant endocrine therapy.In Italian Breast Centers, partners of Senonetwork, we could not observe any treatment delay or change in standard clinical practice for BC care during the 2020 pandemic year, compared to 2019 pre-pandemic year. This finding is in contrast with the globally reported decrease in the performance of the Italian Breast Centers due to the COVID-19 pandemic, and has to be linked to the sharp selection of Senonetwork Breast Centers.

Fitness for work (FFW) in health care workers poses multidisciplinary challenges because of management problems scientific and ethical implications and the implementation of preventive interventions in health care settings. All the relevant stakeholders, including the General Manager, Medical Director, worker's representative, the person responsible for prevention and protection, forensic medicine expert, the person responsible for prevention and health safety at public administration level, commented on: danger to third parties; FFW formulation; human resource management; stress; professional independence; role of the person responsible for prevention and protection and of the person responsible for prevention at public administration level; professional responsibilities. Opinions are reported regarding the main problems related to the role of the Occupational Physician in FFW formulation, such as the difficult balance between autonomy and independence, limited turnover and aging of workforce, need of confidentiality and respect for professional status of the HCW prevalence of susceptibility conditions, rights and duties of stakeholders. The most significant result was the request by the Lombardy Region for more quality in risk assessment and health surveillance; to maintain uniform conduct over all the local health authorities, to allow the board in charge of examining appeals against FFW to fully cooperate with the occupational physician; due attention to the person/worker; the opportunity to convene referral boards for complex FFW management; the challenge of stress management and the need for an observatory for psychological discomforts; the importance of the ICOH Code of Ethics and avoidance of conflicts of interests; the need for individual risk assessment and risk management; the concept of sharing responsibilities and of a real multidisciplinary approach.

Tuberculosis (TB) is still a threat for healthcare workers (HCW), due to the non decreasing incidence, the spread of drug-resistance, the introduction of new tests for the screening, the relevant costs of surveillance of exposed subjects. These issues implicate a revision of activities to prevent TB in health-care settings.A multidisciplinary working group, led by occupational physicians, examined the activities to prevent TB performed in 9 Italian hospitals and reviewed the literature, with the aim to formulate evidence-based procedures.In the considered hospitals, 23.000 HCW are classified as exposed to TB, out of 32.000 HCW exposed to biological risks; yearly, about 6000 subjects are screened for preventive, periodical or post-exposure surveillance and 110-130 chemoprophylaxis are prescribed. A high proportion of HCW (54-75%) refused or interrupt to assume the drugs. In the period 2004-2008, 14 occupational TB were diagnosed (9/100.000 HCW exposed to biological risks).Critical issues are the availability of a specific, written TB control plan, including risk assessment, protocols for identifying, evaluating, managing infectious TB patients, health surveillance, education programs, specifically addressed to increase Standard Precaution adoption and compliance to the screening and to adequate risk perception. Risk assessment identify HCW to be included in TB testing (characterized by low positive predictive value), unrecognized TB and environmental control needed; TB risk classification should include no more than 3 or 4 classes and performed by assessing the issues suggested in the Italian guideline. Tubercolin skin test should be used for HCW screening, adding in vitro test in specific circumstances (for example, skin test positivity in BCG vaccinated HCW); the frequency of the screening should not exceed 2 years. Periodical revision of preventive activities should follow up to date scientific literature and need appropriate data computing.

The biological risk from exposure to bloodborne pathogens in health care environments represents a frequent prevaand widespread risk, involving a large number of exposed workers. On the basis of the available scientific innovations, the recent legislation regarding health and safety of workers and the experiences of SIMLII guidelines on health surveillance (HS) workers exposed to biological risk, a multicenter study was carried out, involving nine relevant hospitals and about 32 000 healthcare workers (HCW). A review of the literature was performed, with particular reference to the last 10 years. For each hospital, protocols of HS have been examined according to tasks and biological risk from bloodborne viruses (HBV, HDV, HCV, HIV) as well as management of HCW infected with this pathogens. Differences of risk management in the hospitals, in relationship also with recommendations of the literature have been evaluated. The literature supplies important indications for HS management of HCW exposed to bloodborne pathogens, with relevant information also for patient safety. Preventive examinations are in line with the recommendations of literature and similar across the hospitals for HCV and HIV, while they are different for HBV. Periodic surveillance was different for the frequency, among the hospitals and also as compared to national SIMLII guidelines. As for management, no differentiation among the hospitals was detected as referred to different risk of exposure, while differences were observed around definitions of restrictions. Finally, good medical practices to support occupational physicians in the prevention and management of HCWs’ exposed to biological risks are suggested

Background. Nosocomial transmission of varicellazoster virus, certain paramixovirus and rubivirus might pose a risk of morbidity for varicella (V), rubella (R), mumps (Mu) and measles (Me) in health care workers (HCW), patients and coworkers. International literature and European legislation recommend preventive interventions to minimize the risk. Methods. A literature review and a seroprevalence study were carried out in 9 hospitals located in north and central Italy, in order to evaluate risk assessment, health surveillance and fitness for work of HCW exposed to V, R, Mu and Me. Antibodies (Ab) against V, R, Mu and Me were determined. For a subgroup of 4 hospitals; sociodemographic, occupational data and sera were collected and analyzed. Results. About 36000 tests on about 9000 HCW were analyzed. Differences in seroprevalence ratios (V 85.7-95.1%, R 47-96.8%, Me 71.4-97.8%, Mu 52.5-87.6%) were detected. In a subgroup, a relevant number of non immune HCW was also found among women in fertile age and areas at higher risk. Statistically significant differences were detected only for selected variables and viruses. Discussion and conclusions. Data of multicenter study confirm literature evidences and allow to define good medical practices for manage and minimize the risk of nosocomial transmission of V, R, Me and Mu. Recommendation are issued about serologic screening on HCW exposed to all 4 viruses thorough the modern analytical techniques, in order to assess risk on individual a group basis and to select priorities for intervention. Vaccination should be prescribed for those HCW non immune, selecting areas and HCW according to priorities.

Introduction. The influenza illness is a concern for health care workers (HCW) due to the potential nosocomial transmission and sickness absenteeism. Immunization and Isolation Precautions might be effective preventive measures. Aims. To formulate recommendations on vaccination in healthcare settings. Methods. A multidisciplinary working group, led by occupational physicians (OP), examined the information on seasonal influenza immunisation campaign in 9 Italian hospitals in the period 2005-2009 and reviewed scientific evidence. Results. Many health organizations recommend vaccination of HCW. The literature shows that seasonal influenza vaccination of healthy adult have a modest effect in reducing work day lost; there is no evidence that it affects transmission or it prevents the disease in elderly residents. These observations might be conditioned by methodological limitations. Further studies are required to avoid the risk of bias and in pediatric settings. The rate of flu vaccination among HCW is widely variable and it depends on individual risk perception and information about efficacy and side effects. In the considered hospitals, in the fiveyears period the vaccination rate ranged between 0 and 29%: the median value was 16-17% in 2005, 2008 and 2009 (only against H1N1 influence), 11% and 13% in 2007 and 2006 respectively. OP participation in the vaccination campaign seems to increase the immunization rate. Discussion. Seasonal influenza immunization of HCW might be effective. We recommend to formalize written procedures in health care settings, to perform data computing and to periodically revise immunization activities and promotion and scientific litterature, with the aim to appropriately address resources.

The board of the Thematic Section on Preventive Medicine for Health Care Workers of the Italian Society of Occupational Medicine and Industrial Hygiene (SIMLII) programmed a national conference on occupational risks of health care workers to be held in late 2009. Main topics will be: a) biohazards; b) biomechanical risk; c) psychosocial factors. Three different working groups were established to tackle critical aspects and suggest practical recommendations to occupational health professionals. Preliminary issues are presented while final results will be presented at the conference on September 2009.

A longitudinal study was implemented in an unpolluted rural area of northern Italy (near Venice), before the start of the operation of a large oil-burning thermoelectric power plant, in order to investigate the effects of the future exposure to air pollution and to elucidate the natural history of obstructive airways diseases. During the first cross-sectional survey, a sample of the general population (n=3,300, 8 to 64 yr of age) performed several lung function tests, and information on risk factors and on the presence of respiratory symptoms were obtained by a standardized questionnaire. There were 712 subjects who were classified as normal on the basis of rigid criteria and who were able to perform satisfactorily a single-breath CO diffusing capacity (DLCOsb) test. The DLCOsb values showed an increase with height and age early in life and a later decrease with age. Two age groups were selected to determine an age at which DLCOsb stopped increasing and began to decline. Reference equations were computed (using age and height) in these 2 different age groups in each of the sexes. Similar equations were calculated for the total lung capacity derived from single-breath helium dilution measurements. The DLCOsb values in this study were higher than reported by other investigators. The method of selection of the study population, the strict criteria for normal, as well as technical, differences probably explain this finding. Reference equations for diffusing capacity corrected to lung volume (DL/VA) were computed only for adults (much greater than 20) in both sexes, because age and height coefficients in young subjects were insignificant.(ABSTRACT TRUNCATED AT 250 WORDS)

A longitudinal epidemiological respiratory study has been started in the North of Italy to investigate the natural history of obstructive airways disease and the long-term effect of SO2 exposure. The first cross-sectional study was completed in this unpolluted area before the activation of a thermoelectric power plant (500 tons of SO2 produced daily). Follow-up surveys are planned after pollution emission starts for a period of ten years. A sample (n = 3289) representative of the general population was drawn from the villages of the area according to the different risks of pollution exposure. Subjects completed questionnaires and performed lung function tests, including forced expiratory (FVC) manoeuvres. For 801 'normal' subjects, prediction equations have been derived in age/sex groups for slow vital capacity (VC) and variables from the FVC manoeuvre. Comparisons with predictions of other studies are reported. Differences among FVC predictions were found, indicating that the use of different criteria for determination of the FVC manoeuvre end-point can affect results. In 'normals' VC was higher than FVC in older subjects. The difference between VC and FVC may be hypothesized as an epidemiological indication of the ageing effect on the mechanical properties of the ventilatory system.
