ABSTRACT

T-cell acute lymphoblastic leukemia (T-ALL) is a T-cell malignancy characterized by cell subsets and enriched with leukemia-initiating cells (LICs). ß-Catenin modulates LIC activity in T-ALL. However, its role in maintaining established leukemia stem cells remains largely unknown. To identify functionally relevant protein interactions of ß-catenin in T-ALL, we performed coimmunoprecipitation followed by liquid chromatography-mass spectrometry. Here, we report that a noncanonical functional interaction of ß-catenin with the Forkhead box O3 (FOXO3) transcription factor positively regulates LIC-related genes, including the cyclin-dependent kinase 4, which is a crucial modulator of cell cycle and tumor maintenance. We also confirm the relevance of these findings using stably integrated fluorescent reporters of ß-catenin and FOXO3 activity in patient-derived xenografts, which identify minor subpopulations with enriched LIC activity. In addition, gene expression data at the single-cell level of leukemic cells of primary patients at the time of diagnosis and minimal residual disease (MRD) up to 30 days after the standard treatments reveal that the expression of ß-catenin- and FOXO3-dependent genes is present in the CD82+CD117+ cell fraction, which is substantially enriched with LICs in MRD as well as in early T-cell precursor ALL. These findings highlight key functional roles for ß-catenin and FOXO3 and suggest novel therapeutic strategies to eradicate aggressive cell subsets in T-ALL.

ABSTRACT

Lung cancer is the deadliest cancer type worldwide with ~ 1.8 million deaths per-year. Smoking accounts for ~ 85% of all cases, with a described joint effect with unhealthy diet in lung cancer risk increase. Public health policies to prevent carcinogens exposure, promote smoking cessation and advocacy for healthy nutrition, are therefore highly recommended. Here we have examined the benefits of the Mediterranean Diet (MedDiet) in protecting against some non-communicable diseases including lung cancer, highlighting the epidemiological and biomolecular aspects of MedDiet anti-inflammatory effect and its interaction with smoking habits closely linked to risk of lung cancer. Considering the high incidence and mortality rates of lung cancer, we discussed also about the global impact that a Planeterranean extension of the benefits of MedDiet could have on controlling lung cancer risk. We also debated the impact of personalized nutrition on lung cancer prevention, considering individual heterogeneity in response to diet plans as well as recent advancements on nutri-omics in lung cancer research, with a specific focus on the role of microRNAs (miRNAs) as a promising nutritional molecular hub for lung cancer prevention. We strongly believe that a deep understanding of the molecular link between food components and genetic/epigenetics factors can expand effective intervention strategies.

ABSTRACT

Little is known as to whether there may be any pathogenetic link between pulmonary carcinoids and neuroendocrine carcinomas (NECs). A gene signature we previously found to cluster pulmonary carcinoids, large cell neuroendocrine carcinoma (LCNEC) and small cell lung carcinoma (SCLC), and which encompassed MEN1, MYC, MYCL1, RICTOR, RB1, SDHA, SRC and TP53 mutations or copy number variations (CNVs), was used to reclassify an independent cohort of 54 neuroendocrine neoplasms (NENs) [31 typical carcinoids (TC), 11 atypical carcinoids (AC) and 12 SCLC], by means of transcriptome and mutation data. Unsupervised clustering analysis identified two histology-independent clusters, namely CL1 and CL2, where 17/42 (40.5%) carcinoids and all the SCLC samples fell into the latter. CL2 carcinoids affected survival adversely, were enriched in T to G transversions or T > C/C > T transitions in the context of specific mutational signatures, presented with at least 1.5-fold change (FC) increase of gene mutations including TSC2, SMARCA2, SMARCA4, ERBB4 and PTPRZ1, differed for gene expression and showed epigenetic changes in charge of MYC and MTORC1 pathways, cellular senescence, inflammation, high-plasticity cell state and immune system exhaustion. Similar results were also found in two other independent validation sets comprising 101 lung NENs (24 carcinoids, 21 SCLC and 56 LCNEC) and 30 carcinoids, respectively. We herein confirmed an unexpected sharing of molecular traits along the spectrum of lung NENs, with a subset of genomically distinct aggressive carcinoids sharing molecular features of high-grade neuroendocrine neoplasms.

ABSTRACT

The June 25, 2024 Judgment of the Court of Justice of the European Union is based on the Industrial Emissions (Integrated Pollution Prevention and Control) Directive 2010/75/EU and confirms its applicability to the Taranto steel plant, reiterating that the concept of pollution includes damage to the environment and human health; the health impact assessment of polluting industrial activities, such as the Ilva steelworks in Southern Italy, must constitute an internal act in the procedures for granting and reviewing the operating permission; all pollutants attributable to the plant that are scientifically recognized as harmful to health must be considered in the assessment procedures. In the case of serious and significant danger to the integrity of the environment and human health, the operation of the installation must be suspended. The Judgment highlights important elements on the level of principle and application, which are extraordinarily useful for environment and health personnel, for open-minded and aware local, regional, and national administrators, and above all for the citizens and communities most exposed to pollutants recognized as harmful to health. Preventive environmental health impact assessments gain renewed strength as tools for evaluative and authorized decision-making on production activities, in a sense of full integration between environment and health. The right to environmental and health protection and prevention is an integral part of the defence of human rights, especially in sacrifice zones such as Taranto and many other sites to be reclaimed, considered by the UN as "places where residents suffer devastating physical and mental health consequences and human rights violations".

ABSTRACT

OBJECTIVES: to evaluate the risk profile of hypospadias in Gela, an Italian National Priority Contaminated Site (NPCS) located in Sicily Region (Southern Italy), characterized by a significant excess of hypospadias in newborn residents compared to data from reference on regional, national, and international basis and, until 2014, by the presence of a petrochemical plant. DESIGN: geographical analyses were conducted by comparing the prevalence of the Gela municipality to prevalence found in Sicily, in a territorial area bordering Gela (ALG), and in the NPCSs of Milazzo and Priolo. The geographical comparisons were conducted for the period 2010-2020, the trend within the Gela NPCS was evaluated by comparing two subperiods (2010-2014 and 2015-2020). SETTING AND PARTICIPANTS: children up to 1 year of age with hypospadias resident in the municipality of Gela in the period 2010-2020. MAIN OUTCOMES MEASURES: crude odds ratios (OR) and respective 95% confidence intervals (95%CI) were used to compare the prevalence observed in Gela and that detected in the comparison areas. RESULTS: excess risk for hypospadias was highlighted in 2010-2020 in Gela vs Sicily (OR 4.45; 95%CI 3.45-5.75), vs ALG (OR 4.29; 95%CI 3.02-6.10), and vs the NPCSs of Milazzo (OR 2.32; 95%CI 1.32-4.07) and Priolo (OR 2.37; 95%CI 1.55-3.62). The between-period comparisons in Gela did not show an important difference between 2010-2014 and 2015-2020 (OR 1.37; 95%CI 0.83-2.24), with a prevalence of 98.9 and 72.4 per 10,000, respectively. CONCLUSIONS: the prevalence of hypospadias in 2015-2020 remains very high, although decreasing when compared to 2010-2014 period. The Gela data, despite the refinery being closed after 2014, suggest a complex situation in which multiple risk factors may play a role.

ABSTRACT

BACKGROUND: Atmospheric pollution has been recognized as the greatest environmental threat to human health. The population of the Venafro Valley, southern Italy, is exposed to emissions from a Waste-To-Energy (WTE) and a cement plant and potentially also to another WTE located in the neighboring region of Lazio; also, the vehicular atmospheric pollution situation is critical. In order to assess the environmental health risk of residents in eight municipalities of the Venafro Valley, a retrospective residential cohort study during 2006-2019 was carried out. METHODS: Four exposure classes were defined by natural-break method, using a dispersion map of nitrogen dioxides (chosen as proxy of industrial pollution). The association between the industrial pollution and cause-specific mortality/morbidity of the cohort was calculated using the Hazard Ratio (HR) through a multiple time-dependent and sex-specific Cox regression adjusting for age, proximity to main roads and socio-economic deprivation index. RESULTS: Results showed, for both sexes, mortality and morbidity excesses in the most exposed class for diseases of the circulatory system and some signals for respiratory diseases. Particularly, mortality excesses in both sexes in class 3 for diseases of the circulatory system [men: HR = 1.37 (1.04-1.79); women: HR = 1.27 (1.01-1.60)] and for cerebrovascular diseases [men: HR = 2.50 (1.44-4.35); women: HR = 1.41 (0.92-2.17)] were observed and confirmed by morbidity analyses. Mortality excesses for heart diseases for both sexes [men-class 3: HR = 1.32 (0.93-1.87); men-class 4: HR = 1.95 (0.99-3.85); women-class 3: HR = 1.49 (1.10-2.04)] and for acute respiratory diseases among women [HR = 2.31 (0.67-8.00)] were observed. Morbidity excesses in both sexes for ischemic heart diseases [men-class 3: HR = 1.24 (0.96-1.61); women-class 4: HR = 2.04 (1.04-4.02)] and in class 4 only among men for respiratory diseases [HR = 1.43 (0.88-2.31)] were also found. CONCLUSIONS: The present study provides several not-negligible signals indicating mitigation actions and deserve further investigations. For future studies, the authors recommend enriching the exposure and lifestyle profile using tools such as questionnaires and human biomonitoring.

ABSTRACT

T-cell acute lymphoblastic leukemia (T-ALL) is an aggressive T-cell malignancy characterized by genotypically-defined and phenotypically divergent cell populations, governed by adaptive landscapes. Clonal expansions are associated to genetic and epigenetic events, and modulation of external stimuli that affect the hierarchical structure of subclones and support the dynamics of leukemic subsets. Recently, small extracellular vesicles (sEV) such as exosomes were also shown to play a role in leukemia. Here, by coupling miRNome, bulk and single cell transcriptome profiling, we found that T-ALL-secreted sEV contain NOTCH1-dependent microRNAs (EV-miRs), which control oncogenic pathways acting as autocrine stimuli and ultimately promoting the expansion/survival of highly proliferative cell subsets of human T-cell leukemias. Of interest, we found that NOTCH1-dependent EV-miRs mostly comprised members of miR-17-92a cluster and paralogues, which rescued in vitro the proliferation of T-ALL cells blocked by γ-secretase inhibitors (GSI) an regulated a network of genes characterizing patients with relapsed/refractory early T-cell progenitor (ETP) ALLs. All these findings suggest that NOTCH1 dependent EV-miRs may sustain the growth/survival of immunophenotypically defined cell populations, altering the cell heterogeneity and the dynamics of T-cell leukemias in response to conventional therapies.

ABSTRACT

High-grade serous ovarian carcinoma (HGSOC) is a highly aggressive and intractable neoplasm, mainly because of its rapid dissemination into the abdominal cavity, a process that is favored by tumor-associated peritoneal ascites. The precise molecular alterations involved in HGSOC onset and progression remain largely unknown due to the high biological and genetic heterogeneity of this tumor. We established a set of different tumor samples (termed the As11-set) derived from a single HGSOC patient, consisting of peritoneal ascites, primary tumor cells, ovarian cancer stem cells (OCSC) and serially propagated tumor xenografts. The As11-set was subjected to an integrated RNA-seq and DNA-seq analysis which unveiled molecular alterations that marked the different types of samples. Our profiling strategy yielded a panel of signatures relevant in HGSOC and in OCSC biology. When such signatures were used to interrogate the TCGA dataset from HGSOC patients, they exhibited prognostic and predictive power. The molecular alterations also identified potential vulnerabilities associated with OCSC, which were then tested functionally in stemness-related assays. As a proof of concept, we defined PI3K signaling as a novel druggable target in OCSC.

ABSTRACT

The methodology of health impact assessment (HIA), originally proposed by WHO, is widely used to predict the potential health effects in a community living in a place in which a new project (e.g., an industrial plant) will be implemented. One of the key quantities to calculate the impact (i.e., the number of attributable cases) is the baseline (i.e., before the project implementation) rate of selected diseases in the community. In a recent paper on this journal, this methodology has been challenged. Specifically, the use of baseline rate has been questioned, proposing to use only the fraction of the baseline rate due to the exposures related to the project, and not the rate due to all risk factors for the disease. In this commentary, we argue that the proposal is logically and epidemiologically unsound, and devoid of scientific motivation. The conclusion that the traditional approach overestimates the health impact should be rejected as based on flawed assumptions. On the contrary, the proposal may produce a (seriously biased) underestimation of attributable cases.

ABSTRACT

In the lung, neuroendocrine tumors (NETs), namely typical and atypical carcinoids, and neuroendocrine carcinomas (NECs), grouping small cell carcinoma (SCLC) and large cell neuroendocrine carcinoma (LCNEC), make up for distinct tumor entities according to epidemiological, genetic, pathologic and clinical data. The proper classification is essential in clinical practice for diagnosis, prognosis and therapy purposes. Through an extensive literature survey, three perspectives on lung NENs have been revised: i) criteria and terminology on biopsy or cytology samples of primaries or metastases; ii) carcinoids with elevated mitotic counts and/or Ki-67 proliferation rates; iii) relevance of molecular landscape to identify new tumor entities and therapeutic targets. Furthermore, a dispute about lung NEN development has been raised according to emerging molecular models. We herein provide a pathology update on practical topics in the setting of lung NENs according to the current classification (recent advances). We have also reappraised the development of these tumors by modeling risk factors and natural history of disease (recent controversies). Combining recent advances and controversies may help clarify our biological understanding of lung NENs and give practical information for the clinical decision-making process.

ABSTRACT

BACKGROUND: Confirmed COVID-19 cases have been registered in more than 200 countries, and as of July 28, 2020, over 16 million cases have been reported to the World Health Organization. This study was conducted during the epidemic peak of COVID-19 in Italy. The early identification of individuals with suspected COVID-19 is critical in immediately quarantining such individuals. Although surveys are widely used for identifying COVID-19 cases, outcomes, and associated risks, no validated epidemiological tool exists for surveying SARS-CoV-2 infection in the general population. OBJECTIVE: We evaluated the capability of self-reported symptoms in discriminating COVID-19 to identify individuals who need to undergo instrumental measurements. We defined and validated a method for identifying a cutoff score. METHODS: Our study is phase II of the EPICOVID19 Italian national survey, which launched in April 2020 and included a convenience sample of 201,121 adults who completed the EPICOVID19 questionnaire. The Phase II questionnaire, which focused on the results of nasopharyngeal swab (NPS) and serological tests, was mailed to all subjects who previously underwent NPS tests. RESULTS: Of 2703 subjects who completed the Phase II questionnaire, 694 (25.7%) were NPS positive. Of the 472 subjects who underwent the immunoglobulin G (IgG) test and 421 who underwent the immunoglobulin M test, 22.9% (108/472) and 11.6% (49/421) tested positive, respectively. Compared to NPS-negative subjects, NPS-positive subjects had a higher incidence of fever (421/694, 60.7% vs 391/2009, 19.5%; P<.001), loss of taste and smell (365/694, 52.6% vs 239/2009, 11.9%; P<.001), and cough (352/694, 50.7% vs 580/2009, 28.9%; P<.001). With regard to subjects who underwent serological tests, IgG-positive subjects had a higher incidence of fever (65/108, 60.2% vs 43/364, 11.8%; P<.001) and pain in muscles/bones/joints (73/108, 67.6% vs 71/364, 19.5%; P<.001) than IgG-negative subjects. An analysis of self-reported COVID-19 symptom items revealed a 1-factor solution, the EPICOVID19 diagnostic scale. The following optimal scores were identified: 1.03 for respiratory problems, 1.07 for chest pain, 0.97 for loss of taste and smell 0.97, and 1.05 for tachycardia (ie, heart palpitations). These were the most important symptoms. For adults aged 18-84 years, the cutoff score was 2.56 (sensitivity: 76.56%; specificity: 68.24%) for NPS-positive subjects and 2.59 (sensitivity: 80.37%; specificity: 80.17%) for IgG-positive subjects. For subjects aged ≥60 years, the cutoff score was 1.28, and accuracy based on the presence of IgG antibodies improved (sensitivity: 88.00%; specificity: 89.58%). CONCLUSIONS: We developed a short diagnostic scale to detect subjects with symptoms that were potentially associated with COVID-19 from a wide population. Our results support the potential of self-reported symptoms in identifying individuals who require immediate clinical evaluations. Although these results come from the Italian pandemic period, this short diagnostic scale could be optimized and tested as a screening tool for future similar pandemics.

ABSTRACT

BACKGROUND: the exposure to a coal-fired power plant has been shown to increase mortality both for cardiovascular and respiratory causes among an exposed cohort in comparison with a cohort of unexposed. Hazard ratios between 1.30 and 1.90 were found for cardiovascular and respiratory mortality. OBJECTIVES: to estimate the individual life shortening among the exposed due to power plant emissions. DESIGN: survival for cardiovascular and respiratory disease in the exposed vs unexposed groups was estimated by the Kaplan-Meier method. For each gender and exposure, a fictitious cohort with a cumulative 30-year follow up was built combining three subcohorts of age at entry of 55-64, 65-74, and 75-84 years, with 10 years of follow up each. Survivals at 10 years in the 55-64-year subcohort were used as initial risks for 65-74-year subcohort; then, survivals at 10 years of the 65-74-year subcohort were used as initial risk in the 75-84-year subcohort. Eventually, 30-years cumulative follow up cohorts were obtained by gender and exposure. Individual life-shortening in people exposed was estimated as time from death of an exposed subject to the subsequent time when the unexposed cohort reached the same risk of the exposed subject at that time of the death. Here, it is proposed a method to take into account causes other than those considered. SETTING AND PARTICIPANTS: 144,018 subjects aged 55-74 years at entry of both genders belonging to the open cohort of residents of 12 municipalities (including Savona) from 2001 to 2013 in the area where the coal-fired power plant of Vado-Quiliano (Liguria Region, Northern Italy) is located. MAIN OUTCOME MEASURES: individual life shortening. RESULTS: after 5 years of follow up, the individual life shortening due to cardiorespiratory causes varied between 972 and 1,822 days for males and from 612 and 1,578 days among females. Taking into account other causes of death, reduces slightly (3% for males of 75 years at death) the estimate of life shortening found in this study. The comparison between the cohorts requires that the exposed and unexposed groups are comparable, except for the exposure, and that causes other than those considered are taken into account. Socioeconomic status had been found to have little effect on cause-specific death risk indicating that, at least in terms of socioeconomic status, the exposed and unexposed groups were similar. Taking into account causes other than those considered slightly reduced the found estimates (3% at age 75 in males). According to the proposal, the life-shortening for the considered causes is easy to calculate and provides an individual indicator of damage. Inferring from group statistics individual estimates could be the most controversial point of this approach. The proposed estimates are the most credible estimate of individual damage for each occurred death among the exposed people. CONCLUSIONS: an increased hazard ratio for a wide series of causes is equivalent to a life shortening among the exposed. A method to produce reasonable estimates of life-shortening is proposed as the effect of exposure at individual level. This approach is simple and do not require sophisticated statistical tools. It appears a promising approach for other settings.

ABSTRACT

Environmental Impact Assessments (EIAs) often conclude with a "low" or at least "negligible" final health impact assessment (HIA) of the industrial plant under assessment. We explore the reasons for this - often simplistic - conclusion and offer suggestions on how to extend the assessment focus from just the plant to an appropriate impact area. For many assessments, the conclusions are easily predictable: the application of available risk functions to modest increases in pollution, in the presence of numerically small populations in the areas of greatest fallout and considering rather rare health outcomes, can only result in quantitatively modest health impacts. This is the classic situation of low sensitivity of the observation system due to the impossibility of containing the type II error (false negatives) since we cannot increase the exposed population at will. The risk is to give the green light to an industrial plant in which the apparently null or very limited damage is simply not properly detectable. There is hardly any trace of these elements in the HIA scoping phase. In environmental complex territories, the renewal or authorization of a new plant should consider not only the impact of the individual plant, but also the health profile of the population concerned and the context in which the industrial project is located. An 'HIA area' is therefore configured, aimed at the complex of environmental pressure factors that insist on the same area of impact of the plant. Epidemiology focuses on the exposed population, considers the 'current' state of health, hazard, and risk information from toxicology, and estimates individual exposure and the effects of exposure. The 'HIA area' can assess the impact of the complex of persistent emission sources, considering in the analysis the health status of the exposed population and the presence of specific vulnerabilities. The proposal is in line with what is already foreseen in the Essential levels of care and Environmental technical performance of the National Health Service.A basic condition is the establishment of functions dedicated to integrated environmental and health surveillance to update the health profile and carry out the 'HIA area' as an accompanying tool for local strategic planning. On these issues, the Italian Environment and Health Network (RIAS) has opened a discussion within the network and with any Italian regions.

ABSTRACT

BACKGROUND: Metabolic reprogramming towards aerobic glycolysis in cancer supports unrestricted cell proliferation, survival and chemoresistance. The molecular bases of these processes are still undefined. Recent reports suggest crucial roles for microRNAs. Here, we provide new evidence of the implication of miR-27a in modulating colorectal cancer (CRC) metabolism and chemoresistance. METHODS: A survey of miR-27a expression profile in TCGA-COAD dataset revealed that miR-27a-overexpressing CRCs are enriched in gene signatures of mitochondrial dysfunction, deregulated oxidative phosphorylation, mTOR activation and reduced chemosensitivity. The same pathways were analysed in cell lines in which we modified miR-27a levels. The response to chemotherapy was investigated in an independent cohort and cell lines. RESULTS: miR-27a upregulation in vitro associated with impaired oxidative phosphorylation, overall mitochondrial activities and slight influence on glycolysis. miR-27a hampered AMPK, enhanced mTOR signalling and acted in concert with oncogenes and tumour cell metabolic regulators to force an aerobic glycolytic metabolism supporting biomass production, unrestricted growth and chemoresistance. This latter association was confirmed in our cohort of patients and cell lines. CONCLUSIONS: We disclose an unprecedented role for miR-27a as a master regulator of cancer metabolism reprogramming that impinges on CRC response to chemotherapy, underscoring its theragnostic properties.

ABSTRACT

Motivation: Breast cancer is the most commonly diagnosed malignancy in women and the second cause of cancer death in developed countries. While advancements in early detection and therapeutic options have led to a significant decrease in mortality, response to treatment is affected by the genetic heterogeneity of the disease. Recent genome-wide DNA mutation analyses revealed the existence of hundreds of low-frequency mutated genes, in addition to known cancer drivers: a finding that is prompting research into the impact of these genes on the pathogenesis of the disease. Results: Herein, we describe a strategy towards the characterization of the role of low-frequency mutated genes in breast cancer. Through the combined analyses of publicly available gene expression and mutational datasets, we identified several Cancer Gene Modules (CMs) that we re-organized in Gene Regulatory Networks (GRN) enriched in low-frequency mutated genes. Importantly, these low-frequency mutated genes were mutually exclusive with known cancer drivers. Finally, we provide evidence that gene expression analysis of these mutated GRNs can predict resistance/sensitivity to chemotherapeutic drugs for breast cancer treatment.

ABSTRACT

Achondroplasia is a rare genetic disorder resulting in short-limb skeletal dysplasia. We present the largest European population-based epidemiological study to date using data provided by the European Surveillance of Congenital Anomalies (EUROCAT) network. All cases of achondroplasia notified to 28 EUROCAT registries (1991-2015) were included in the study. Prevalence, birth outcomes, prenatal diagnosis, associated anomalies, and the impact of paternal and maternal age on de novo achondroplasia were presented. The study population consisted of 434 achondroplasia cases with a prevalence of 3.72 per 100,000 births (95%CIs: 3.14-4.39). There were 350 live births, 82 terminations of pregnancy after prenatal diagnosis, and two fetal deaths. The prenatal detection rate was significantly higher in recent years (71% in 2011-2015 vs. 36% in 1991-1995). Major associated congenital anomalies were present in 10% of cases. About 20% of cases were familial. After adjusting for maternal age, fathers >34 years had a significantly higher risk of having infants with de novo achondroplasia than younger fathers. Prevalence was stable over time, but regional differences were observed. All pregnancy outcomes were included in the prevalence estimate with 80.6% being live born. The study confirmed the increased risk for older fathers of having infants with de novo achondroplasia.

ABSTRACT

BACKGROUND: Dandy-Walker (DW) malformation is a rare and severe congenital anomaly of the posterior fossa affecting the development of the cerebellum and the fourth ventricle. OBJECTIVE: The aim of this study was to investigate the epidemiology of DW malformation, using data from the European population-based registries of congenital anomalies in the European Surveillance of Congenital Anomalies network. METHODS: Anonymous individual data on cases of DW malformation diagnosed in 2002-2015 from 28 registries in 17 countries were included. Prevalence, prenatal detection rate, proportions and types of associated anomalies were estimated. Cases of DW variant were considered and analysed separately. RESULTS: Out of 8,028,454 surveyed births we identified a total of 734 cases, including 562 DW malformation cases and 172 DW variant cases. The overall prevalence of DW malformation was 6.79 per 100,000 births (95% CI 5.79-7.96) with 39.2% livebirths, 4.3% foetal deaths from 20 weeks gestational age, and 56.5% terminations of pregnancy after prenatal diagnosis of foetal anomaly at any gestation (TOPFA). The livebirth prevalence was 2.74 per 100,000 births (95% CI 2.08-3.61). The prenatal detection rate was 87.6%. Two-hundred and seventy-three cases (48.6%) had an isolated cerebral anomaly and 24.2, 19.2 and 5.5% cases were associated with other structural non-cerebral anomalies, chromosomal anomalies and genetic syndromes respectively. The prevalence of DW variant was 2.08 per 100,000 (95% CI 1.39-3.13). CONCLUSIONS: This European population-based study provides the epidemiological profile of DW malformation. All birth outcomes were analysed and TOPFA represented more than half of the cases. About 50% of the cases of DW malformation were associated with other non-cerebral anomalies. Large populations and all birth outcomes are essential in epidemiological studies of rare and severe congenital anomalies.

ABSTRACT

In the period 2015-2017 a Health Impact Assessment, HIA, was carried out in the Municipalities of Viggiano and Grumento Nova, in Val D'Agri, where since 2001 the oil first treatment plant, COVA, has been active. HIA envisaged the constant involvement of local communities and a multidisciplinary scientific group. Seven scientific articles have been published on: review of evidence on non-methane hydrocarbons; diffusion model of air pollutants emitted by the COVA; characteristics of the HIA process; investigation on volatile organic compounds, odorous substances and citizens' reports; sample study on respiratory function using spirometry and questionnaire; residential cohort study on mortality and hospitalization; analysis of media outputs in a critical period. The results showed environmental and health impacts related to the population's area of residence. In addition to environmental-health surveillance activities, the preventive HIA approach emerges as a preferential way for reducing communities' exposure to recognized pollutants and sustaining environmental justice options.
