RESUMEN
OBJECTIVES: We aimed to estimate the fraction of deaths from ovarian cancer attributable to asbestos exposure in Lombardy Region, Italy, using a novel approach that exploits the fact that ovarian cancer asbestos exposure is associated with pleural cancer and other risk factors for breast cancer. METHODS: This ecological study is based on the Italian National Institute of Statistics mortality data. We formulate a trivariate Bayesian joint disease model to estimate the attributable fraction (AF) and the number of ovarian cancer deaths attributable to asbestos exposure from the geographic distribution of ovarian, pleural and breast cancer mortality at the municipality level from 2000 to 2018. Expected deaths and standardised mortality ratios were calculated using regional rates. RESULTS: We found shared dependencies between ovarian and pleural cancer, which capture risk factors common to the two diseases (asbestos exposure), and a spatially structured clustering component shared between ovarian and breast cancer, capturing other risk factors. Based on 10 462 ovarian cancer deaths, we estimated that 574 (95% credibility interval 388-819) were attributable to asbestos (AF 5.5%; 95% credibility interval 3.7-7.8). AF reaches 34%-47% in some municipalities with known heavy asbestos pollution. CONCLUSIONS: The impact of asbestos on ovarian cancer occurrence can be relevant, particularly in areas with high asbestos exposure. Estimating attributable cases was possible only by using advanced Bayesian modelling to consider other risk factors for ovarian cancer. These findings are instrumental in tailoring public health surveillance programmes and implementing compensation and prevention policies.

BACKGROUND: Per- and polyfluoroalkyl substances (PFAS) are associated with many adverse health conditions. Among the main effects is carcinogenicity in humans, which deserves to be further clarified. An evident association has been reported for kidney cancer and testicular cancer. In 2013, a large episode of surface, ground and drinking water contamination with PFAS was uncovered in three provinces of the Veneto Region (northern Italy) involving 30 municipalities and a population of about 150,000. We report on the temporal evolution of all-cause mortality and selected cause-specific mortality by calendar period and birth cohort in the local population between 1980 and 2018. METHODS: The Italian National Institute of Health pre-processed and made available anonymous data from the Italian National Institute of Statistics death certificate archives for residents of the provinces of Vicenza, Padua and Verona (males, n = 29,629; females, n = 29,518) who died between 1980 and 2018. Calendar period analysis was done by calculating standardised mortality ratios using the total population of the three provinces in the same calendar period as reference. The birth cohort analysis was performed using 20-84 years cumulative standardised mortality ratios. Exposure was defined as being resident in one of the 30 municipalities of the Red area, where the aqueduct supplying drinking water was fed by the contaminated groundwater. RESULTS: During the 34 years between 1985 (assumed as beginning date of water contamination) and 2018 (last year of availability of cause-specific mortality data), in the resident population of the Red area we observed 51,621 deaths vs. 47,731 expected (age- and sex-SMR: 108; 90% CI: 107-109). We found evidence of raised mortality from cardiovascular disease (in particular, heart diseases and ischemic heart disease) and malignant neoplastic diseases, including kidney cancer and testicular cancer. CONCLUSIONS: For the first time, an association of PFAS exposure with mortality from cardiovascular disease was formally demonstrated. The evidence regarding kidney cancer and testicular cancer is consistent with previously reported data.

Space-time analysis of mortality risk is useful to evaluate the epidemiologic transitions at the subnational level. In our study, we analysed the death certificate records for lung cancer in Italy in 1995-2016, obtained from the Italian National Institute of Statistics. Our objective was to investigate the spatial-temporal evolution of lung cancer mortality by sex and province of residence (n = 107) using the birth cohort as relevant time axis. We built Bayesian space-time models with space-time interactions. Among males (n = 554 829), mortality peaked in the 1920-1929 cohort, followed by a generalised decline. Among females (n = 158 619), we found novel original evidence for a peak in the 1955-1964 cohort, equivalent to a 35-year delay, with a downward trend being observed thereafter. Over time, the documented north-south decreasing mortality gradient has been replaced by a west-east decreasing gradient. Naples has become the province at highest risk in Italy, both among males and females. This pattern is consistent with an epidemiologic transition of risk factors for lung cancer to the south-west of the country and raises concern, because 5-year age-standardised net survival from the disease in this geographic area is lower than in northern and central Italy. The variability of mortality rates among provinces has changed over time, with an increasing homogeneity for males and an opposite trend for females in the more recent birth cohorts. These unprecedented observations provide evidence for a profound spatio-temporal transition of lung cancer mortality in Italy.

BACKGROUND: Older adults living in long-term care facilities (LTCF) have been severely affected by COVID-19. Hospice care (HC) facilities and palliative care are essential in treating patients dying from COVID-19. In Italy, little is known about the impact of COVID-19 on deaths in LTCF and the care provided in HC to COVID-19 patients. AIM: To assess overall and case-specific mortality in 2020 in LTC and HC facilities in comparison to the previous five years (2015-2019). METHODS: We performed a descriptive study using data derived from the Italian national "Cause of Death" registry-managed by the Italian National Institute of Statistics-on deaths occurred in LTC and HC facilities during 2020 and the period 2015-2019. RESULTS: Number of deaths significantly increased in 2020 compared with 2015-2019 in LTCF (83,062 deaths vs. 59,200) and slightly decreased in hospices (38,788 vs. 39,652). COVID-19 caused 12.5% of deaths in LTCF and only 2% in hospices. Other than COVID-19, in 2020, cancer accounted for 77% of all deaths that occurred in HC, while cardiovascular diseases (35.6%) and psychotic and behavioral disorders (10%) were the most common causes of death in LTCF. Overall, 22% of the excess mortality registered in Italy during 2020 is represented by the deaths that occurred in LTCF. DISCUSSION AND CONCLUSION: LTCF were disproportionally affected by COVID-19, while the response to the pandemic in HC was limited. These data can help plan strategies to limit the impact of future epidemics and to better understand residential care response to COVID-19 epidemic.

The SENTIERI Project analyses the health profile of the populations residing in Italian national priority contaminated sites in specific calendar periods using a cross-sectional approach. An aspect that has not been evaluated so far is the analysis over a long period, for understanding the changes in health profiles over time and studying them also in function of the changes occurred in the territories. This article studies temporal trends by birth cohort and calendar period for overall mortality and lung cancer mortality from 1980 to 2018, separately for men and women, for three sites: Priolo (Sicily Region, Southern Italy), Pitelli (Liguria Region, Northern Italy), and Terni-Papigno (Umbria Region, Central Italy). A method for selecting the temporal model that best fits the data is then proposed. General mortality presents complex temporal profiles when considering cumulative risks, and usually the most important temporal axis is the birth cohort for cumulative SMRs (i.e., after adjusting for trends in the reference population). For lung cancer, the most important time axis is the birth cohort and the age-cohort model is the most appropriate, in particular for men of Priolo and Terni.

This paper describes the development and the envisioned use of concept maps in the framework of the SENTIERI communication strategies as an information and scientific communication tool applied to epidemiological surveillance in contaminated sites. The concept map of SENTIERI 2019-2022 was designed and implemented to foster access to complex scientific information ensuring usability of the contents and communication with the various stakeholders. The concept map aims to promote environmental health literacy in contaminated sites. The methodology adopted to create the map includes the following phases: 1. choice of a dynamic focus question; 2. selection of the representative terms of the addressed topics; 3. elaboration of the glossary of the selected terms; 4. representation of the links among the selected terms; 5. identification of the significant propositions that make explicit the meaning of each link. Online access to the map is guaranteed by the Mindomo software. The use of the concept map promotes active learning of the topics that characterize SENTIERI 2019-2022 through knowledge paths chosen because of the specific interests and learning purposes. The concept map derives from the integration of specific approaches of the epidemiological discipline with those of the social sciences and offers the possibility of developing site-specific maps through the interactions with local actors and the integration of elements related to emerging problems as well as institutional and local interests.

Since 2006, epidemiological surveillance of populations living in Italian contaminated sites has been ongoing (SENTIERI Project). Updated global estimates of mortality (2013-2017) and hospitalization (2014-2018) are reported. The excess deaths (observed-expected) for the main groups of diseases were calculated for all the 46 sites together. Through a random-effect meta-analysis of the standardized mortality and hospitalization rates (SMR/SHR), the pooled SMR/SHR for all the sites and their groupings were estimated. In the 46 sites, 8,342 exceeding deaths (1,668/year) were estimated, 4,353 in males and 3,989 in females, resulting in an excess risk of 2% in both genders. The risk of hospitalization for all causes was in excess of 3%. These excesses are mainly attributable to malignant tumours. In subgroups of sites, exceeding SMRs were observed for all mesotheliomas and pleural mesotheliomas, lung and colorectal cancers in both genders. SHR for all causes were observed in excess in the first year of life (+8%), in the group 0-19 and 20-29 years (+3-5%); no excesses of mortality were observed in the group 0-29 years.

INTRODUCTION ADN OBJECTIVES: The Sixth Report presents the results of the "SENTIERI Project: implementation of the permanent epidemiological surveillance system of populations residing in Italian Sites of Remediation Interest", promoted and financed by the Italian Ministry of Health (Centre for Disease Control and Prevention - CCM Project 2018). The aim of this study is to update the mortality and hospitalization analyses concerning the 6,227,531 inhabitants (10.4% of the Italian population) residing in 46 contaminated sites (39 of national interest and 7 of regional interest). The sites include 316 municipalities distributed as follows: 15 in the North-East (20.3% of the investigated population); 104 in the North-West (12% of the investigated population), 32 in the Centre (12.6% of the investigated population), 165 in the South and Islands (55.5% of the investigated population). Analyses were carried out on the paediatric-adolescent (1,128,396 residents) and youth (665,284 residents) population, and a study on congenital anomalies (CA) was carried out at sites covered by congenital malformation registers. Accompanying the epidemiological assessments, site-specific socioeconomic conditions were examined and an overall estimate of excess risk for populations residing at contaminated sites was drawn up. By means of a systematic review of the scientific literature, the epidemiological evidence on causal links between sources of environmental exposure and health effects was updated to identify pathologies of a priori interest. METHODOLOGY: In the 46 sites included in the SENTIERI Project, mortality (time window: 2013-2017) and hospital admissions (time window: 2014-2018) of the general population of all ages, divided by gender, and of the paediatric-adolescent (0-1 year, 0-14 years, 0-19 years), youth (20-29 years), and overall (0-29 years) age groups, divided by gender, were analysed. In 21 sites, CA diagnosed within the first year of life were studied. Standardised mortality ratios (SMR) and hospitalization ratios (SHR) were calculated with reference to the rates in the regions to which the sites belong. The reference population was calculated net of residents in the sites. CA were studied by calculating the prevalence per 10,000 births and the ratio, multiplied by 100, between the cases observed at the site and those expected on the basis of the prevalences observed in the reference area (region or sub-regional area of belonging, according to the geographical coverage of the registry). The socioeconomic condition studied in the 46 sites is based on the convergence of three deprivation indicators with respect to the reference region: deprivation index at municipal level, deprivation index at census section level, premature mortality indicator (age range 30-69 years) for chronic non-communicable diseases. For the estimation of excess risk for the entire study population, meta-analysis of the mortality and hospitalization risk estimates for each site was carried out and the number of excess deaths estimated for the sites as a whole. The epidemiological evidence was updated through a systematic literature review (January 2009-May 2020), following the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. The search was carried out on the search engines MEDLINE, EMBASE and Web of Science; the quality of the studies included in the review was assessed using the AMSTAR 2 checklist for systematic reviews and the NewCastle-Ottawa Scale for observational studies in the case of cohort and case-control studies and a modified version thereof for ecological and cross-sectional studies. The update was based on the selection of 14 systematic reviews, 15 primary studies, 6 monographs/reports from international scientific organisations on health effects due to the presence of environmental exposure sources. RESULTS: Mortality. The a priori causes of interest that occur most frequently in excess are, in descending order: malignant lung cancer, malignant mesothelioma of the pleura, malignant bladder cancer, respiratory diseases, non-Hodgkin lymphomas, malignant liver cancer, all malignant tumours, malignant colorectal cancer, malignant stomach cancer, total mesotheliomas, malignant breast cancer, and asbestosis. Hospitalization. The a priori causes of interest that occur most frequently in excess are represented in descending order by: respiratory diseases, malignant lung cancer, malignant tumours of the pleura, malignant bladder cancer, malignant breast cancer, malignant liver cancer, asthma, malignant colorectal cancer, all malignant tumours, malignant stomach cancer, non-Hodgkin's lymphomas, acute respiratory diseases, leukaemias. The differences observed between mortality and hospitalization can be attributed to the intrinsic characteristics of the diseases (higher or lower lethality, gender differences in incidence), lifestyles, and occupational phenomena. Age classes. Excesses of general mortality were observed in the first year of life at the Manfredonia, Basso Bacino Fiume Chienti, Litorale Domizio Flegreo and Agro Aversano sites; in the 0-1 year and 0-19 year age groups at Casale Monferrato; in the paediatric age group at Serravalle Scrivia and at the Trento Nord site; in the 0-19 year age group at Sassuolo Scandiano; in the young age group (0-29 years) at the two municipalities of Cerchiara and Cassano (Crotone-Cassano-Cerchiara site). With regard to hospitalization due to natural causes, risk excesses in both genders are found in the first year of life in 35% of the sites (Porto Torres industrial areas, Bari-Fibronit, Basso bacino fiume Chienti, Bolzano, Crotone-Cassano-Cerchiara, Cerro al Lambro, Bologna ETR large repair workshop, Gela, Manfredonia, Massa Carrara, Pioltello Rodano, Pitelli, Priolo, Sesto San Giovanni, Trento Nord, and Trieste). These same sites, with the addition of Casale Monferrato, Cengio e Saliceto, Serravalle Scrivia, and Sulcis-Iglesiente-Guspinese (total: 43% of sites), show excesses for all natural causes, in both genders, even in the paediatric-adolescent age group (0-19 years). Among young adults (20-29 years), the analyses show excesses of hospitalization for all natural causes in both genders in the Bolzano, Crotone-Cassano-Cerchiara, Gela, Manfredonia, Pitelli, Priolo, and Sulcis-Iglesiente-Guspinese sites. Among young women only, excesses for all natural causes are also found in Brescia Caffaro, Brindisi, Broni, Casale Monferrato, Crotone-Cassano-Cerchiara, Falconara Marittima, Fidenza, and Massa Carrara. Congenital anomalies. In the 21 sites investigated for CA, 10,126 cases of CA, validated by participating registers, were analysed out of 304,620 resident births. Genital CA is the subgroup for which the greatest number of excesses was observed (in 6 out of 21 sites). The available evidence does not allow a causal link to be established between the excesses observed for specific subgroups of ACs and exposure to industrial sources, but the results suggest further action. The interpretation of the results appears, in fact, particularly complex as the scientific literature on the association between exposure to industrial sources and AC is very limited. Socioeconomic status. The sites in which the indicators converge to show the presence of fragility are: Litorale Vesuviano area, Val Basento industrial areas, Basso Bacino fiume Chienti, Biancavilla, Crotone-Cassano-Cerchiara, Litorale Domizio Flegreo and Agro Aversano, Livorno, Massa Carrara, Trieste. Global impact. Over the period 2013-2017, an estimated 8,342 excess deaths (CI90% 1,875-14,809) or approximately 1,668 excess cases/year, 4,353 excess deaths among males (CI90% 334-8,372) and 3,989 among females (CI90% -1,122;9,101). The pooled excess risk of general mortality is 2% in both genders (pooled SMR 1.02; CI90% 1.00-1.04). The proportion of excess deaths to total observed deaths is almost constant over time, rising from 2.5% in 1995-2002 to 2.6% in 2013-2017. The number of deaths in absolute value is also very similar between the periods analysed. Deaths from all malignant tumours contribute the most by accounting for 56% of the observed excesses, the excess risk of mortality from malignant tumours across all sites, compared to the reference populations, is 4% in the male population (pooled SMR 1.04; CI90% 1.01-1.06) and 3% among the female population (pooled SMR 1.03; CI90% 1.01-1.05). Hospitalization (2014-2018) in the 46 sites as a whole was in excess of 3% for all causes, in both genders, for all major disease groups (males: SHR pooled 1.03; CI90% 1.01-1.04 - females: SHR pooled 1.03; CI90% 1.01-1.05). The results for the pooled estimates at the 46 sites on the general population, both with regard to mortality and hospitalization, are consistent in indicating excess risk in both genders for all the diseases considered and, in particular, for all malignancies. A total of 1,409 paediatric-adolescent deaths and 999 young adult deaths were observed, and the pooled analysis of mortality across the 46 sites showed no critical issues, with pooled estimates for all causes, perinatal morbid conditions and all malignancies falling short of expectations. The analysis of hospitalizations, on the other hand, showed an excess risk of 8% (males: SHR pooled 1.08; CI90% 1.03-1.13 - females: SHR pooled 1.08; CI90% 1.03-1.14) for all causes in the first year of life, and in paediatric-adolescent and juvenile age of 3-4% among males (age 0-19 years: SHR pooled 1.04; CI90% 1.02-1.06 - age 20-29 years: SHR pooled 1.03; CI90% 1.00-1.05) and 5% among females (in both age groups; SHR pooled 1.05; CI90% 1.02-1.08). The pooled analysis of mortality for the a priori identified diseases reported excesses for specific diseases in the group of sites with sources of exposure associated with them. Mortality from total mesotheliomas is three times higher at sites with asbestos present (males:pooled SMR 3.02; CI90% 2.18-3.87 - females: pooled SMR 3.61; CI90% 2.33-4.88) and that from pleural mesotheliomas more than two times higher at the group of sites with asbestos and port areas (males: pooled SMR 2.47; CI90% 1.94-3.00 - females: pooled SMR 2.43; CI90% 1.67-3.19). Lung cancer was in excess by 6% among males (pooled SMR 1.06; CI90% 1.03-1.10) and 7% among females (pooled SMR 1.07; CI90% 1.00-1.13). In addition, there are excess mortalities for colorectal cancer at sites with chemical plants, by 4 % among males (SMR pooled 1.04; CI90% 1.01-1.08) and 3 % among females (SMR pooled 1.03; CI90% 1.00-1.07) and for bladder cancer among the male population of sites with landfills (+6 %: SMR pooled 1.06; CI90% 1.02-1.11). Among the diseases of a priori interest, stomach and soft tissue cancers are at fault as a cause of death among all the sites considered. LITERATURE REVIEW: The update of the epidemiological evidence underlying the Sixth SENTIERI Report has highlighted in the general population a possible association, previously undiscovered, between certain diseases and residence near petrochemical and steel plants, landfills, coal mines and asbestos sources. CONCLUSIONS AND PERSPECTIVES: Despite the fact that this is an ecological study, and the excesses of pathologies with multifactorial aetiology can never be mechanically attributed solely to the environmental pressure factors that exist or existed in the areas studied, the ability to identify the excesses found in the contaminated sites investigated by the SENTIERI Project confirms the validity of this method of assessing the site-specific health profile, based on the use of epidemiological evidence to identify pathologies of interest a priori. In interpreting the data and lending robustness to what has been observed, comparison with the results obtained in previous Reports is essential. The global estimates give an overall picture that shows excess mortality and hospitalization in these populations compared to the rest of the population, and show how, for specific pathologies, comparable effects are produced at sites with similar contamination characteristics. The themes developed in the in-depth chapters broaden the vision and understanding of the complex interactions between environment and health, describe the possibilities offered by new ways of communicating the results, and confirm the modernity of a Project that began way back in 2006, and that could be grafted onto the objectives of the National Recovery and Resilience Plan within the framework of the Operational Programme Health, Environment, Biodiversity and Climate.

Currently, there are more and more requests for a characterization of the health profile by populations living in areas affected by several types of environmental contaminations, notably for the presence of previously unknown and accidentally discovered landfills. The aim of the present paper is to describe the mortality profile of the residents of Piazzola sul Brenta (Veneto Region, Northern Italy). In this area, it was discovered an environmental contamination of the soil in the nearby of a large school building, where was formerly located a phosphate fertiliser plant. Using cause of death data provided by the Italian National Institute of Health, 10th International Classification 2013-2018, standardised mortality ratios (SMRs) and 90% confidence intervals (CIs) were calculated by gender and specific causes of death. Compared to the provincial reference population, no excess was found, for both genders, for all-causes mortality and for circulatory diseases. However, an excess for malignant tumours was found, 523 observed deaths over 498 expected deaths, an SMR of 105 (IC90% 98-113), and 85% probability of excess cancer mortality; lung cancer (SMR 117; IC90% 100-135) and lympho-hematopoietic tumours (in men only, SMR 134; IC90% 101-178).In light of these results and of the potential human exposure to carcinogenic substances, present results support further epidemiological investigations and environmental remediation.

BACKGROUND: Italy has been the first country at European level to implement a population-based public health registry dedicated to rare diseases. This study describes the current situation of the Italian National Rare Diseases Registry (NRDR) and compares its data with those from the National Hospital Discharge Database (HDD). METHODS: Three rare diseases were analysed: Huntington disease (HD), Hereditary Haemorragic Telangiectasia (HHT) and Prader-Willi Syndrome (PWS), selected for their different characteristics. The two sources (NRDR and HDD) were linked: incidence rate ratio (IRR), sensitivity and predictive positive value (PPV) were calculated. RESULTS: Incidence rates from NRDR and from HDD were compared by age groups, and IRR calculated: 1.08 for HD, 1.41 for HHT, 1.21 for PSW. For HD, sensitivity was 0.52 and PPV 0.48; for HHT sensitivity was 0.71 and PPV 0.52; for PWS the sensitivity was 0.71 and PPV 0.58. We found a strong regional variability in the results. CONCLUSIONS: The integrated use of the two sources helps tracking those cases that are not captured by the Registry; further, it is a precious tool to accurately describe clinical histories of rare disease affected individuals, in terms of concomitant pathologies and medical procedures performed during hospitalization.

OBJECTIVE: The Italian reporting system for thyroid cytology classifies indeterminate lesions as TIR3A (low risk) or TIR3B (high risk) and is meant to provide practical guidance rather than a detailed consideration of morphological features. We aimed to assess which cytological features have the most diagnostic value and whether they are effective in classifying nodules as either TIR3A or TIR3B and in predicting histological outcomes. METHODS: Thyroid fine-needle aspirates from 111 indeterminate nodules were reviewed blinded to clinical information, TIR3A/TIR3B classification, and histology in order to assess which cytological features (pooled into artefacts, smear background, architectural and nuclear atypia, and oncocytes) differentiate TIR3A from TIR3B, and benign from malignant histological outcomes. RESULTS: Of the cytological features examined, those specific for TIR3B included high cellularity, nuclear atypia, oncocyte predominance and transgressing vessels. Features specific for TIR3A included artefacts, low cellularity and oncocyte sparseness. Other features, such as microfollicules/trabeculae, were non-specific. Due to the different distributions of these features, three TIR3B subgroups were identifiable: follicular lesions with oncocytic changes, pure follicular lesions, and follicular lesions with nuclear atypia, whereas no subgroups were identifiable in TIR3A. Nuclear atypia was a significant indicator of malignancy, whereas oncocyte predominance was not a reliable predictor of malignancy. High cellularity and microfollicules/trabeculae were not indicative of any histological outcome. CONCLUSIONS: The majority of the assessed features were good predictors of histological outcomes. The TIR3A category included undefined nodules due to the absence of characterising features, whereas the TIR3B category included nodules with a greater number of distinguishing features.

INTRODUCTION AND OBJECTIVES: This volume provides an update of the health status of the populations living in the National Priority Contaminated Sites (NPCSs) included in the SENTIERI Project. This update is part of an epidemiological surveillance programme carried out in NPCSs, promoted by the Italian Ministry of Health as a further step of a project started in 2006, when the health status of residents in contaminated sites was first addressed within the National Strategic Program "Environment and Health". The Report focuses on five health outcomes: mortality, cancer incidence, hospital discharges, congenital anomalies, and children, adolescents and young adults' health. A key element of SENTIERI project is the a priori evaluation of the epidemiological evidence of a causal association between the considered cause of disease and the exposure. When an a priori evidence is identified, it is given a greater importance in the comment of the study findings. METHODS: The present update of the SENTIERI Project concerns 45 NPCSs including in all 319 Italian Municipalities (out of over 8,000 Municipalities), with an overall population of 5,900,000 inhabitants at the 2011 Italian Census. Standardized Mortality Ratios (SMRs) and Standardized Hospitalization Ratios (SHRs), referring to a time window of 2006-2013, were computed for all the 45 NPCSs, using as a reference the corresponding mortality and hospitalization rates of the Regions where each NCPS is located. Standardized Incidence Ratios (SIRs) were computed by the Italian Association of Cancer Registries (AIRTUM) for the 22 NPCSs served by a Cancer Registry. AIRTUM covers about 56% of Italy, with partly different time-windows. SIRs have been estimated using as reference population the 4 macroareas in which Italy is divided (North-West, North-East, Centre, South). Prevalence of congenital anomalies was computed for 15 NPCSs. RESULTS: An all-cause excess of 5,267 and 6,725 deaths was observed, respectively, in men and women; the cancer death excess was of 3,375 in men and 1,910 in women. It was estimated an excess of cancer incidence of 1,220 case in men and 1,425 in women over a five-year time window. With regard to the diseases with an a priori environmental aetiological validity, an excess for malignant mesothelioma, lung, colon, and gastric cancer, and for non-malignant respiratory diseases was observed. Cancer excess mainly affected NPCSs with presence of chemical and petrochemical plants, oil refineries, and dumping hazardous wastes. An excess of non-malignant respiratory disease was also detected in NPCSs in which steel industries and thermoelectric plants were present. An excess of mesothelioma was observed in NPCSs characterized by presence of asbestos and fluoro-edenite; it was also observed where the presence of asbestos was not reported in the legislative national decrees which define the NPCS areas. It is worth noting that, even if the presence of asbestos is not reported in many NPCSs legislative decrees, petrochemical plants and steel industries, for instance, are often characterized by the presence of a large amount of this mineral that, in the past, was extensively used as an insulating material. For the first time, the present Report includes a focus on the health status of children and adolescents (1,160,000 subjects, aged 0-19 years), and young adults (660,000 subjects, aged 20-29 years). Among infants (0-1 year), an excess of 7,000 hospitalizations was observed, 2,000 of which due to conditions of perinatal origin. In the age class 0-14, an excess of 22,000 hospitalizations for all causes was observed; 4,000 of them were due to acute respiratory diseases, and 2,000 to asthma. Data on cancer incidence for subjects aged 0-24 years were derived from general population cancer registries for twenty NPCSs, and from children cancer registries (age group: 0-19 years) for six NPCSs; 666 cases where diagnosed in the age group 0-24 years, corresponding to an excess of 9%. The main contributions to this excess are from soft tissue sarcomas in children (aged 0-14 years), acute myeloid leukaemia in children (aged 0-14 years) and in the age group 0-29 years, non-Hodgkin lymphoma and testicular cancer in young adults (aged 20-29 years). In seven out of 15 NPCSs, an excess prevalence rate of overall congenital anomalies at birth was observed. Congenital anomalies excesses included the following sites: genital organs, heart, limbs, nervous system, digestive system, and urinary system. CONCLUSIONS: The main findings of SENTIERI Project have been the detection of excesses for the diseases which showed an a priori epidemiological evidence of a causal association with the environmental exposures specific for each considered NPCS. These observations are valuable within public health, because they contribute to priority health promotion activities. Looking ahead, the health benefits of an improved environmental quality might be appreciated in terms of reduction of the occurrence of adverse health effects attributable to each Site major pollutant agents. Due to the methodological approach of the present study, it was not possible to adjust for several confounding factors reported to be risk factors for the studied diseases (e.g., smoking, alcohol consumption, obesity). Even if excesses of mortality, hospitalization, cancer incidence, and prevalence of congenital anomalies were found in several NPCSs, the study design and the multifactorial aetiology of the considered diseases do not permit, for all of them, to draw conclusions in terms of causal links with environmental contamination. Moreover, it must be taken into consideration that economic factors and the availability of health services may also play a relevant role in a diseases outcome. A few observations regarding some methodological limitations of SENTIERI Project should be made. There is not a uniform environmental characterisation of the studied NPCSs in term of quality and detection of the pollutants, because this information is present in different databases which at present are not adequately connected. Moreover, the recognition of a contaminated site as a National Priority Site is based on soil and groundwater pollution, and the available information on air quality is currently sparse and not homogenous. Another limitation, in term of statistical power, is the small population size of many NPCSs and the low frequency of several health outcomes. A special caution must be paid in data interpretation when considering the correspondence between the contaminated areas and the municipality boundaries, as they do not always coincide perfectly: in some cases, a small municipality with a large industrial site, while in other settings only a part of the municipality is exposed to the sources of pollution. Furthermore, all available health information systems are currently accessible at municipality level. The real breakthrough is essentially comprised of the development and fostering of a networking system involving all local health authorities and regional environmental protection agencies operating in the areas under study. The possibility to integrate the geographic approach of SENTIERI Project with a set of ad hoc analytic epidemiological investigations, such as residential cohort studies, case control studies, children health surveys, biomonitoring surveys, and with socioepidemiological studies, might greatly contribute to the identification of health priorities for environmental remediation activities. Finally, as discussed in the last section of the report, there is a need to adopt, in each NPCS, a two-way oriented communication plan involving public health authorities, scientific community, and resident population, taking into account that the history, the cultural frame and the network of relationships specific of each local context play a major role in the risk perception perspective.

The integration of current data sources is now a practice widely used in epidemiology, especially in the environmental field. To better describe the health profile of populations residing in proximity to areas characterized by a "strong environmental pressure", the combined use of multiple indicators (i.e., mortality, hospitalization, cancer incidence) is recommended. To choose an indicator is complex, as indicators should be contextualized and they need to be related to the several issues involved in the studied pathology. This chapter explores the general considerations that are to be addressed both at the time of the study design, during the selection of outcomes and of the proper data sources, and at the time of the discussion of the results, when different and complementary data are compared. A special focus is devoted to the case of mesothelioma.

INTRODUCTION: Peritoneal mesothelioma, a very rare and lethal malignancy, has not been investigated as extensively as pleural mesothelioma, although the role of asbestos exposure in its occurrence is well-known. Data from Italy are relevant, as it was the largest European asbestos producer, and asbestos was widely used in many economic activities. METHODS: A population-based mortality and incidence analysis was performed in Italy. Data sources were the National Multiple-causes-of-death Database (1995-2010) and the Italian Mesothelioma Register (1993-2008). RESULTS: We found an increasing trend of age standardized mortality rates in men, but no clear trend in women; moreover, we showed significant risks of death in several northern regions, formerly heavy asbestos users; finally, mortality/incidence ratios similar for both genders (about 0.8) were estimated. CONCLUSIONS: The study, based on national data, showed a higher risk of mortality from and incidence of peritoneal mesothelioma in areas with formerly heavy exposure to asbestos.

The Report considers three health outcomes - mortality, cancer incidence and hospital discharges - studied using homogenous methods and using data from official sources, namely the National Institute of Statistics (Istat), Italian Network of Cancer Registries (AIRTUM) and the Health Ministry. The timeframes of observation are: 2003-2010 for mortality, 1996-2005 for cancer incidence and 2005-2010 for hospital discharges. The causes of death are those examined by the SENTIERI Project. Hospital discharges are analysed with reference to the main diagnosis. The study of cancer incidence applies to the sites selected by AIRTUM. Statistical parameters (SMR, Standardized Mortality Ratio; SIR, Standardized Incidence Ratio; SHR, Standardized Hospitalization Ratio) were computed with a 90% confidence interval; the estimators were adjusted for age and socioeconomic status.

Of the 18 National Priority Contaminated Sites (NPCSs) analysed in this Report, some have a single source of environmental contamination (such as fluoro-edenite in Biancavilla). In most cases, however, we are looking at multiple heterogeneous sources of contamination. In this respect, the a priori causal evaluation of the association between diseases and environmental exposures in NPCSs, based on epidemiological evidence, can help trace the health impact back to specific types of environmental exposure. There are several cases in which the project's findings have been consistent with a priori evidence: stomach cancer (both genders, excess cancer incidence) in the Fidenza NPCS; stomach cancer (women, excess mortality, cancer incidence and hospital discharges) in the Laguna di Grado e Marano NPCS; excess hospitalisation from respiratory diseases in Brescia-Caffaro, Milazzo and Terni Papigno NPCSs; excesses for non-Hodgkin lymphomas and melanoma (incidence and hospitalisation in men and women) and breast cancer (incidence and hospital discharges, women) in Brescia-Caffaro NPCS. In preorder to properly evaluate the population's health profile, we must also observe whether results remain consistent for all three health outcomes or in both genders. The first is the case of excess mortality, cancer incidence and hospital discharges for bladder cancer (men) in Porto Torres and diseases of the urinary tract in the Basso bacino del fiume Chienti NPCS). Gender consistency is observed, for instance, for all cancer in Bolzano, Porto Torres, Venice, Litorale Domizio Flegreo, Priolo, and Taranto, for all causes in Taranto, Litorale Domizio Flegreo and Trieste. The health impact in the various NPCSs needs to be considered carefully and used as a springboard for further analytical research that could confirm and explain causal links to specific environmental exposures. The observations can, however, already be considered as a basis for mandatory primary prevention measures.

Introduction: SARS-CoV-2 infection has been associated with the onset or persistence of symptoms in the long-term after the acute infection is resolved. This condition known as Post-COVID, might be particularly severe and potentially life-threatening. However, little is known on the impact of post-COVID condition on mortality. Aim of the present study is to assess and quantify Post-COVID deaths in Italy in years 2020 and 2021, based on an analysis of death certificates. Methods: Data from the Italian National Cause of Death Register were analyzed. ICD-10 code U09.9, released by the World Health Organization in September 2020, was used to identify the 'Post-COVID' condition. Numbers of post-COVID deaths from October 2020 to December 2021 were analyzed. Rates of post-COVID deaths were calculated for the year 2021. Results: Between October 2020 and December 2021, 4,752 death certificates reporting post-COVID condition were identified. Of these, 14.9% (n = 706) occurred between October and December 2020 and 85.1% (n = 4,046) in 2021. In 46.0% of post-COVID-related deaths, the underlying cause of death was COVID-19. Other frequent underlying causes were heart disease (14.3% of cases), neoplasms (9.2%), cerebrovascular diseases (6.3%) and Alzheimer's disease and other dementias (5.5%). The mortality rate related to post-COVID conditions in year 2021 was 5.1 deaths per 100 thousand inhabitants and it increased with increasing age. Men showed a higher mortality rate than women (4.3 deaths per 100 thousand in women and 6.0 deaths per 100 thousand in men). Discussion: Post-COVID conditions contributed to a substantial number of deaths in Italy. Strategies to identify the population at risk of severe long-term consequences of SARS-CoV-2 infection and interventions aimed at reducing this risk must be developed.
RESUMEN
Background: Obesity is associated with numerous severe diseases necessitating intensive healthcare for diagnosis and treatment. Most patients with obesity, especially in its severe form, require at least one hospitalization. However, few studies in Italy have assessed the burden of obesity on the National Health System. This study aims to routinely estimate the 'disease burden' by analyzing hospital admissions related to severe obesity. Subjects: We analyzed the medical records of the Italian national hospital discharge database, including all patients older than 18 years discharged with the diagnosis of 'severe obesity'.' We included patients who underwent bariatric surgery, even without an explicit obesity code, such as laparoscopic restrictive gastric procedures, other stomach operations, and high gastric bypass. Special focus was given to those who underwent abdominal reshaping surgery. The cross-sectional survey PASSI in Italy served as an additional data source to estimate. The phenomenon was described using appropriate indicators, including rates and ratios between rates. Linear regression was employed to analyze trends in standardized rates over time. Results: Between 2014 and 2021, a total of 243,325 patients were discharged with a severe obesity code in Italy. Among these patients, 36.8% underwent at least one bariatric surgery procedure. We investigated the types of bariatric surgery procedures performed. The most frequent procedure was "other operations on the stomach," where sleeve gastrectomy is included which also appears to be steadily increasing during the study period together with the gastric bypass, while the gastric bondage is decreasing over time. Conclusion: These findings underscore the significant burden of severe obesity on Italy's healthcare system, a burden that is progressively increasing. The growing utilization of bariatric surgery suggests an escalating trend toward adopting drastic solutions to combat this health issue.

Background/Objectives: Endometriosis is a female chronic inflammatory disease in which endometrial tissue develops outside the uterine cavity. It is a complex pathology, which significantly contributes to morbidity in premenopausal women, leading to chronic pain, infertility, and subfertility negatively impacting physical and emotional well-being and the overall quality of life. The public health burden of endometriosis remains elusive and challenging to determine, and this uncertainty can lead to inadequate healthcare services and treatments. The objective was to estimate the incidence and prevalence of endometriosis in Italy using the hospital discharge records database via a population-based retrospective study, nationwide between 2011 and 2020. Methods: From the National Hospital Discharge Database, we selected all admissions with a diagnosis of endometriosis (ICD-9-CM, codes 617.x), supported by the presence of a procedure code of laparoscopy or any other surgical procedure allowing for direct visualisation of the lesions. The main outcomes measured: incidence and prevalence of endometriosis were estimated for the entire 2011-2020 period and by individual year, analysing the time trend and variability in different geographical areas of Italy. Results: There were a total of 134,667,646 women aged 15-50 years with one or more hospitalisations for endometriosis in all Italian hospitals. The incidence of endometriosis in Italy during this period was 0.839 per 1000 women (CI95% 0.834-0.844), exhibiting a statistically significant decreasing trend over the years. A discernible north-south gradient was observed, with higher rates documented in the northern regions. The prevalence rate stood at 14.0 per 1000 during the same period, and a similar north-south geographical gradient was identifiable in the prevalence rates as well. Conclusions: The utilization of national-level hospital data enables the generation of incidence and prevalence data for endometriosis without variations in methods and definitions, facilitating the evaluation of temporal trends and regional comparisons. Understanding and quantifying this phenomenon is essential for appropriate healthcare planning in various Italian regions.
RESUMEN
BACKGROUND: Excess mortality (EM) can reliably capture the impact of a pandemic, this study aims at assessing the numerous factors associated with EM during the COVID-19 pandemic in Italy. METHODS: Mortality records (ISTAT 2015-2021) aggregated in the 610 Italian Labour Market Areas (LMAs) were used to obtain the EM P-scores to associate EM with socioeconomic variables. A two-step analysis was implemented: (1) Functional representation of EM and clustering. (2) Distinct functional regression by cluster. RESULTS: The LMAs are divided into four clusters: 1 low EM; 2 moderate EM; 3 high EM; and 4 high EM-first wave. Low-Income showed a negative association with EM clusters 1 and 4. Population density and percentage of over 70 did not seem to affect EM significantly. Bed availability positively associates with EM during the first wave. The employment rate positively associates with EM during the first two waves, becoming negatively associated when the vaccination campaign began. CONCLUSIONS: The clustering shows diverse behaviours by geography and time, the impact of socioeconomic characteristics, and local governments and health services' responses. The LMAs allow to draw a clear picture of local characteristics associated with the spread of the virus. The employment rate trend confirmed that essential workers were at risk, especially during the first wave.
