In the past months, mass vaccination represented the turning point of the global battle against the COVID-19 pandemic, an unprecedented challenge for physicians, healthcare professionals, health systems and pharmaceutical companies. More than 6 billion doses of vaccine have been administered to date, covering nearly 50% of the world’s population. Although the vaccination campaign is still thwarted by spread of fake news disseminated by a ubiquitous antivaxxer movement, accumulating real-life data1 confirm the favourable safety profile already demonstrated in phase III clinical trials.2 Despite the lack of a steady literature evidence,3 the potential role of vaccines in promoting autoimmunity continues to intrigue many researchers. The theoretical basis of this association relies on the possible molecular mimicry between macromolecular components of the vaccine and specific human proteins and the exuberant immune response elicited by adjuvants contained in vaccines.4 Adverse events (AEs) associated with COVID-19 vaccines are usually mild and mainly restricted to injection site reactions. Interestingly, among systemic AEs, arthralgia is one of the most common.2 To the best of our knowledge, only isolated cases5 of arthritis developed after COVID-19 …

Asbestos is one of the major worldwide occupational carcinogens. The global burden of asbestos-related diseases (ARDs) was estimated around 231,000 cases/year. Italy was one of the main European asbestos producers until the 1992 ban. The WHO recommended national programs, including epidemiological surveillance, to eliminate ARDs. The present paper shows the estimate of the burden of mortality from ARDs in Italy, established for the first time. National standardized rates of mortality from mesothelioma and asbestosis and their temporal trends, based on the National Institute of Statistics database, were computed. Deaths from lung cancer attributable to asbestos exposure were estimated using population-based case-control studies. Asbestos-related lung and ovarian cancer deaths attributable to occupational exposure were estimated, considering the Italian occupational cohort studies. In the 2010–2016 period, 4400 deaths/year attributable to asbestos were estimated: 1515 from mesothelioma, 58 from asbestosis, 2830 from lung and 16 from ovarian cancers. The estimates based on occupational cohorts showed that each year 271 deaths from mesothelioma, 302 from lung cancer and 16 from ovarian cancer were attributable to occupational asbestos exposure in industrial sectors with high asbestos levels. The important health impact of asbestos in Italy, 10–25 years after the ban, was highlighted. These results suggest the need for appropriate interventions in terms of prevention, health care and social security at the local level and could contribute to the global estimate of ARDs.

Objectives The aim of this study was to estimate the attributable proportion (AP) of mesothelioma resulting from living in or close to major Italian industrially contaminated areas. Methods For populations living close to 39 sites of "national priority for remediation", incident mesothelioma cases were extracted from the Italian National Mesothelioma Registry (ReNaM) in the period 2000‒2011. Each site was classified in one of seven asbestos risk groups (RG) on the basis of the type of industrial plants. RG were ranked by the a priori evidence on asbestos risk. The AP for each RG was calculated as the meta-analytic estimate of AP of sites of the same group by gender and age class (0–64, 65–74, ≥75 years). The sex ratio (men/women) was computed for each RG. Results Among men, the AP by age class had the same gradient in each RG, with the highest values in the age class 0–64 years and the lowest in the ≥75 class; in the age class 0–64 years, the AP was positive in each RG, >90% in the presence of asbestos cement factories and harbors with shipyards. Among women, the overall AP decreased by RG, with negative values in the last two ranked RG; the AP by age class was variable without a definite gradient. The sex ratio was close to one only in the RG "only asbestos-cement factories"; the highest value (9.6) was observed in the age class 0–64 years in the RG "harbors with shipyard". Conclusions The integration of a geographic- and case-based approach provides valuable insights into occupational and environmental determinants of mesothelioma risk in industrially contaminated sites.

Background This study is part of a national plan of epidemiological surveillance of malignant mesothelioma (MM) mortality in Italy. The paper shows the results of malignant peritoneal mesothelioma (MPeM) mortality study in Italian Regions and municipalities. Methods National Bureau of Statistics data for MPeM municipal mortality (ICD-10, Code C45.1) were analyzed in the time-window 2003–2014: mortality standardized rates (reference Italian population, census 2011), temporal trends of the annual national rates, Standardized Mortality Ratios and a municipal clustering analysis were performed. Results 747 deaths for MPeM were recorded (0.10/100,000): 464 in men (0.14/100,000) and in 283 women (0.07/100,000). No significant MPeM mortality temporal trend was found. Seventeen municipalities showed excesses of mortality for MPeM in at least one gender and/or overall population. Four clusters in male population, and one in women were identified. Conclusions The study identifies some areas where remediation activities and/or health care actions may be warranted.

Objectives To investigate subclinical and clinical abnormalities in retinal and choroidal vascular plexuses in patients with SSc by means of optical coherence tomography angiography (OCT-A). Methods A total of 20 consecutive SSc patients were recruited and compared with 20 healthy subjects. Quantitative analysis of vessel density (VD), choriocapillaris plexus flow index (CCP-FI) and choroidal vascularity index were performed on OCT-A images in the superficial capillary plexus (SCP), deep capillary plexus (DCP) and CCP for all patients. Images were further reviewed by two independent readers for the assessment of qualitative abnormalities, including tortuosity, rarefaction areas, megacapillaries and macular-foveal capillaries. Results The DCP-VD in the whole scan and in the perifoveal, superior, inferior, nasal and temporal regions was significantly lower in the SSc group. The CCP-FI was significantly higher in SSc patients. When comparing SSc patients with and without digital ulcers, significantly decreased SCP-VD was demonstrated in the whole, perifoveal, superior, inferior, temporal and nasal regions. No difference in any of the OCT-A parameters was observed when comparing patients with and without interstitial lung disease. Qualitative analysis of OCT-A revealed at least one abnormality in 95% of patients. Conclusion We showed the ability of OCT-A to disclose early ocular vascular abnormalities in patients with SSc. Our results may represent a hypothesis-generating basis for exploring the potential role of OCT-A in diagnosis, monitoring and prognosis stratification in SSc.

Malignant mesothelioma (MM) is a rare neoplasm caused by asbestos. Mortality from MM in ≤50 years old people, considering the long latency, is likely related to asbestos exposure in childhood. Mortality from MM (C45, ICD10 code) is described among ≤50 years (ys) old people in Italy, in 2003-2016. National and regional Standardized Rates (SRs) were computed by age-class. The North-South trend of regional SRs, increasing in50ys age-class, showed a flat cline in ≤50ys old people. Municipal Standardized Mortality Ratios (SMRs) were computed, with respect to regional figures, for ≤50 ys old population. In Italy, 487 people ≤50 ys old died from MM, in 2003-2016 (2.5% of all MM deaths), corresponding to 35/year. The highest SMRs were observed in Northern Regions, the most industrialized areas. Exceeding SMRs were found in 10 municipalities where former asbestos-cement plants, shipyards, and a quarry contaminated by fluoro-edenite fibres were present. Early mortality from MM, proxy of childhood environmental asbestos exposure, deserves particular concern.

to analyse the asbestos-related diseases risk among the former workers of Sacelit asbestos-cement plant, operating in San Filippo del Mela (Sicily: 1958- 1993).cohort study.228 subjects were employed in Sacelit from 1958 to 1993. Due to the available observation periods, the analyses of the different outcomes were performed for the subjects alive at the beginning of the respective follow up periods: mortality (1986-2018) was analysed for 204 subjects (177 men, 27 women), hospitalization (2001-2016) for 164 workers (139 men, 25 women) and the incidence of mesothelioma (1998-2016) was estimated for 178 subjects (153 men, 25 women).mortality (Standardized Mortality Ratio: SMR) and hospitalization (Standardized Hospitalization Ratio: SHR) from specific diseases were analysed. Incidence (Standardized Incidence Ratio: SIR) of mesothelioma cases was detected, also. SMR (1986-2014), SHR (2001-2016) and SIR (1998-2016), with 95% Confidence Intervals, were computed with respect to the regional rates, with STATA11.in the men cohort, mortality from lung (17 cases, SMR 2.83) and pleural cancers (5 cases, SMR 30) and from asbestosis (15 cases, SMR 1,930) was in excess. The risk of hospitalization was in excess, in both genders, from lung cancer (men: 6 cases, SHR 4.1; women: 2 cases, SHR 8.6) and asbestosis (men: 17 cases, SHR 1,304; women: 6 cases, SHR 2,455). The incidence of mesothelioma was in excess in men (5 cases, SIR 23.9); no female cases of mesothelioma were observed.a high occurrence of asbestos-related diseases in the cohort, particularly among men, was observed. The excess of hospitalization from asbestosis and lung cancer was highlighted also in women. The prosecution of the on-going health surveillance plan is particularly appropriated.

A yearlong sampling campaign (2012–2013) was conducted in six major cities of the Veneto region to investigate the spatial-temporal trends and the factors affecting the polycyclic aromatic hydrocarbon (PAHs) variations and identify the local sources. Sixty samples per city were collected for analyses in every alternate month (April, June, August, October, December, and February): 10 samples per sampling site in 10 consecutive days of the months selected. Samples were ultrasonically extracted with acetonitrile and processed through high-performance liquid chromatography. Total Σ-PAH concentrations ranged from 0.19 to 70.4 ng m−3 with a mean concentration of 11.5 ng m−3. The mean benzo[a]pyrene (BaP) concentration reached 2.0 ng m−3, which is two-times higher than the limit set by the European Union. BaP contributed for 17.4% to the total concentration of PAHs, which showed the same pattern across the region with maxima during cold months and minima in the warm period. In this study, PAHs showed an inverse relationship with temperature, solar radiation, wind speed, and ozone. According to this study, biomass burning for household heating and cooking, followed by gaseous PAHs absorption on particles due to low atmospheric temperature, were the main reasons for increasing PAHs concentration in winter. Health risk, evaluated as lifetime lung cancer risk (LCR), showed a potential carcinogenic risk from the airborne BaPTEQ six-fold higher in the cold season than in the warm one. Diagnostic ratios and conditional probability functions were used to locate the sources, and results confirmed that local emission, overall domestic heating, and road transport exhausts were responsible for higher concentration rates of PAHs as well as of PM2.5.

Background: Recent evidence demonstrated a potential role of complement C3 as a candidate biomarker of cardiometabolic risk in the general population.Objective: Aim of the present study was to investigate the correlation between complement C3 levels and comorbid type 2 diabetes (T2DM) in rheumatoid arthritis (RA) patients.Methods: For the present study, 40 consecutive diabetic RA patients (RA/T2DM(+) group) and 80 consecutive RA patients without diabetes (RA/T2DM-group) were recruited.Results: Patients in the RA/T2DM(+) group were significantly older (p < 0.0001), had a longer RA duration (p < 0.0001) and higher disease activity (p = 0.006) compared to controls. Moreover, patients in the RA/T2DM(+) group had significantly higher levels of ESR (p < 0.0001), CRP (p < 0.0001) and complement C3 (p < 0.0001). A logistic regression model was built to ascertain the effect of selected variables (age, RA duration, BMI, ESR, C3, lnCRP, corticosteroid use) on the likelihood that patients have T2DM. Longer RA duration, ESR and C3 were associated with an increased likelihood of being classified as T2DM. Finally, we built ROC curves to evaluate the predictivity of RA duration, complement C3 and the combination of both variables on the likelihood of being diagnosed with T2DM. The area under the ROC curve was 0.79 (p < 0.0001) for RA duration, 0.71 (p < 0.0001) for complement C3 and 0.89 (p < 0.0001) for the combination of both variables.Conclusion: According to our data complement C3 levels can predict the presence of T2DM in RA patients.

Numerous municipalities in Italy currently experience asbestos health impact, in particular excesses of pleural mesothelioma incidence and mortality. This paper presents an integrated analysis of epidemiological studies and communication actions in affected municipalities to highlight how communication has been implemented depending on health impact evidence and involvement of local stakeholders.Four case studies are identified concerning industrial and natural sources of asbestos exposure having different diseases burden. This integrated analysis benefited from multidisciplinary skills.Evidence of different stakeholders engagement is presented to emphasize their role in the communication process. Similarities and differences among case studies allowed us to identify lessons-learned to be transferred in other asbestos contaminated sites.The adoption of communication strategies and practices, since the very early evidence of asbestos health impact, represents a relevant contribution for epidemiological and health surveillance, particularly for those communities where asbestos health impact has only been recently reported.

Objective.The purpose of the ULISSE study was to evaluate the prevalence of clinical and ultrasonographic (US) entheseal involvement in patients with psoriatic arthritis (PsA), psoriasis, and fibromyalgia syndrome (FMS).Methods.In this cross-sectional multicenter study, patients with PsA and psoriasis (not taking systemic therapy) and FMS underwent a clinical evaluation of the entheses, and a B-mode and power Doppler examination of 6 pairs of entheses.Results.The study analyzed 140 patients with PsA, 51 with psoriasis, and 51 with FMS. Clinical and US examinations were performed in 1960 and 1680 entheses in the PsA group, and 714 and 612 entheses both in the psoriasis group and in the FMS group. In both per-patient and per-enthesis evaluation, the frequency of entheseal tenderness was higher in patients with FMS (92% of the patients and 46% of the entheses, compared with 66%/23% in the PsA group and 59%/18% in the psoriasis group). With US examination, signs of entheseal involvement were more frequent in both the per-patient and per-enthesis evaluation in PsA and psoriasis (about 90% of patients in both the PsA and psoriasis groups and 75% of patients in the FMS group had at least 1 site affected, and 54%, 41%, and 27% of the pairs of entheses in, respectively, PsA, psoriasis, and FMS patients showed at least 1 enthesis involved).Conclusion.The ULISSE study indicated that enthesitis is a common feature in patients with PsA, those with psoriasis, and in those with FMS if only clinical examination is used. US entheseal assessment showed findings more consistent with the 3 disorders.

AIM: Vascular damage and fibrotic process represent the pathophysiological hallmarks of systemic sclerosis (SSc). Peripheral microangiopathy can be early detected by nailfold videocapillaroscopy (NVC), whereas recent studies suggest that ultrasound real time elastosonography (US-RTE) can be a useful tool to evaluate the reduction of skin elasticity. The aim of our study was to investigate possible correlations between NVC microvascular alterations and finger tissue stiffness evaluated with US-RTE in SSc subjects. METHODS: 20 subjects (16 women and 4 men) who met the ACR criteria for SSc were recruited. All subjects underwent complete clinical examination, NVC and US-RTE evaluation. US-RTE was carried out on both the hands, at the level of the palmar surface of the distal phalanx of the fingers. RESULTS: 10 subjects showed limited disease subset (LSS) and 10 showed diffuse disease subset (DSS). Eight patients had 'Early/Active' NVC pattern and 12 had 'Late' NVC pattern. DSS subjects showed highest skin stiffness values when compared to both LSS (p = 0.03) and healthy subjects (p = 0.002). Multiple regression analysis shows an independent association between Late NVC pattern and skin stiffness (R2 = 0.24, p = 0.027). CONCLUSION: This study demonstrates, for the first time, a strong relationship between microvascular alterations and skin stiffness, evaluated with US-RTE, in SSc patients.

To describe the baseline characteristics of the patients enrolled in the QUality of life in patients with Axial SpondyloARthritis (QUASAR) study in terms of quality of life (QoL), disease activity, therapy adherence, and work ability in a real-world setting.QUASAR is an Italian multicentre, prospective 12-month observational study, including consecutive adult patients classified as axial spondyloarthritis (axSpA) according to the Assessment of SpondyloArthritis international Society criteria for axSpA.Of 512 patients enrolled in 23 rheumatology centres, 80.7% had ankylosing spondylitis (AS) and 19.3% had non-radiographic axSpA (nr-axSpA). Mean ages were 34.1±13.3 years at axSpA symptoms onset and 39.5±13.0 years at diagnosis. Of the patients, 51.4% presented with ≥1 extra articular manifestation (EAM); the most common were psoriasis (17.8%) and uveitis (16.4%). Patients with nr-axSpA and AS had similar EAM rates, disease activity, and QoL. Biologic disease-modifying anti-rheumatic drugs (bDMARDs; 83.2%) were the most commonly received medication, followed by conventional synthetic DMARDs (22.9%) and non-steroidal anti-inflammatory drugs (NSAIDs; 16.6%). At baseline, higher treatment satisfaction was reported with bDMARDs which, together with NSAIDs, were associated with the best overall scores for disease activity, function, and QoL in the overall population and AS subgroup.QUASAR is the first Italian prospective study that comprehensively evaluated a large axSpA patient sample in a real-world setting. This interim analysis at baseline confirmed that i) patients with AS and nr-axSpA have similar QoL and disease burden, ii) nearly all axSpA patients receive treatment, and iii) bDMARDs and NSAIDs, overall, yield better disease activity and QoL.

A yearlong sampling campaign (2012-2013) was conducted in six major cities of the Veneto region to investigate the spatial-temporal trends and the factors affecting the polycyclic aromatic hydrocarbon (PAHs) variations and identify the local sources. Sixty samples per city were collected for analyses in every alternate month (April, June, August, October, December, and February): 10 samples per sampling site in 10 consecutive days of the months selected. Samples were ultrasonically extracted with acetonitrile and processed through high-performance liquid chromatography. Total Σ-PAH concentrations ranged from 0.19 to 70.4 ng m

Malignant mesothelioma (MM) is causally linked to asbestos exposure with an estimated etiological fraction of 80% or more.Standardized rates of all mesothelioma (C45, ICD-10) and malignant pleural mesothelioma (C45.0, ICD-10) mortality in Italy were computed at national and regional levels, for the period 2003-2014. Standardized Mortality Ratios (SMRs, with 95% Confidence Intervals) were calculated for each of the 8047 Italian municipalities, for both diseases, with respect to Regional figures. A geographical clustering analysis at municipal level was performed, applying SatScan methods.In Italy, 16,086 persons (about 1,340/year) died for MM, in analysed period. National Standardized rates of MM mortality are 3.65/100,000 in men and 1.09/100,000 in women, with an increasing annual trend, among male population. The highest rates were found in men from Northern Regions. Significant clusters (p 0.10) were found corresponding to areas that hosted major asbestos-cement plants, naval shipyards, petrochemical plants and refineries. Furthermore, excesses were found corresponding to chemical and textile industries; the latter involving, particularly, female population. Excesses were found also in areas near the chrysotile mine of Balangero, and in Biancavilla, a town with a stone quarry contaminated by fluoro-edenitic fibres; an excess of MM mortality was observed among male population living in a minor island where a Navy shipyard is located.Mortality for mesothelioma in Italy is still increasing, twenty-six years after the asbestos ban. Epidemiological surveillance of mesothelioma mortality allows to detect the temporal trend of the disease and highlights previously unknown or underestimated sources of asbestos exposure.

Nailfold Video Capillaroscopy (NVC) is a simple and powerful tool used in rheumatology to recognize morphological and/or functional abnormalities in the microcirculation. Despite its key role in the early diagnosis of Systemic Sclerosis (SSc), its diffusion is confined to central public hospitals. In this paper, the design and fabrication of a low-cost NVC platform are presented, which enables a distributed measuring station for improving the diffusion of this technique in a non-hospital setting. An automated measuring system is implemented for the evaluation of quantitative NVC parameters assisting in the interpretation of a non-specialist. Comparison between the scores obtained from a commercial capillaroscope and the proposed device showed an overall good agreement.

OBJECTIVES: This study aimed to (i) describe mesothelioma incidence in the Italian national priority contaminated sites (NPCS) on the basis of data available from the Italian National Mesothelioma Registry (ReNaM) and (ii) profile NPCS using Bayesian rank analysis. METHODS: Incident cases of mesothelioma and standardized incidence ratios (SIR) were estimated for both genders in each of the 39 selected NPCS in the period 2000–2011. Age-standardized rates of Italian geographical macro areas were used to estimate expected cases. Rankings of areas were produced by a hierarchical Bayesian model. Asbestos exposure modalities were discussed for each site. RESULTS: In the study period, 2683 incident cases of mesothelioma (1998 men, 685 women) were recorded. An excess of mesothelioma incidence was confirmed in sites with a known past history of direct use of asbestos (among men) such as Balangero (SIR 197.1, 95% CI 82.0–473.6), Casale Monferrato (SIR 910.7, 95% CI 816.5–1012.8), and Broni (SIR 1288.5, 95% CI 981.9–1691.0), in sites with shipyards and harbors (eg, Trieste, La Spezia, Venice, and Leghorn), and in settings without documented direct use of asbestos. The analysis ranked the sites of Broni and Casale Monferrato (both genders) and Biancavilla (only for women) the highest. CONCLUSIONS: The present study confirms that asbestos pollution is a risk for people living in polluted areas, due to not only occupational exposure in industrial settings with direct use of asbestos but also the presence of asbestos in the environment. Epidemiological surveillance of asbestos-related diseases is a fundamental tool for monitoring the health profile in NPCS.

Background Since more than 50 years glucocorticoids represent the milestone in the treatment of inflammatory diseases, including rheumatoid arthritis (RA). However, many patients with RA present a circadian rhythm in symptoms severity with a significant worsening in the morning, that correlates with cyclic changes in circulating hormones and cytokines. Classical steroid therapy given in the morning fails to intercept this pathophysiological phenomenon. In the last years, a novel formulation of prednisone has been developed in order to better fit these variations, improve efficacy and minimize adverse events (chronotherapy). This modified-release (MR) prednisone is administered in the evening at 10.00 p.m. and absorbed after about 4 hours. Methods In this article, we reviewed the recent clinical trials evaluating the efficacy of MR prednisone in RA patients, including two randomized controlled double-blind clinical trials Circadian Administration of Prednisone in Rheumatoid Arthritis - 1 (CAPRA-1) and CAPRA-2 and other nonrandomized observational studies. Results According to the available evidence, MR prednisone seems effective in ameliorating morning stiffness in RA patients. Conclusion In conclusion, the use of MR prednisone in the treatment regimen could be a costeffective choice in a significant proportion of RA patients, particularly in those with a clinical phenotype characterized by morning stiffness or morning recrudescence of pain. With regards to the safety, MR prednisone adverse events profile does not differ from that of IR glucocorticoids.

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.

in Italy, National Priority Contaminated Sites (NPCSs) are defined as of concern for remediation; most of them are sites with a long-lasting industrial activity.the study aims to estimate the burden of disease from mesothelioma in NPCSs.mesothelioma incidence in the period 2000-2011 was estimated for the populations residing in the 39 Italian NPCSs. Data were taken from the Italian National Mesothelioma Registry (ReNaM). NPCSs were ranked into risk groups (RGs) on the basis of the presence of the following asbestos-exposing activities: 1. asbestos-cement plants; 2. asbestos mines; 3. harbours with shipyards; 4. illegal dumping sites containing asbestos; 5. petrochemicals and/or refineries, and/or steel plants; 6. chemical plants and/or landfills without explicit mention of asbestos. For the population residing in each NPCS, crude rates per 100,000 per year and number of observed minus expected cases (Obs-Exp) by gender were computed. Expected cases were calculated using the age-class rates of a reference population (the geographical macroarea of every NPCS). For every RG, the meta-analytic estimate of the attributable proportion (AP), i.e., the proportion of cases attributable to the local context, was computed, being the AP for each NPCS expressed as (Obs-Exp/Obs) x100.the total number of mesothelioma cases estimated in the considered period of 12 years is 2,741 (2,048 males, 693 females). The total number of Obs-Exp cases was 1,531 (1,178 in males, 353 in females). In males, crude rate ranges from 71.5 in the RG1 to 3.0 in RG4, while in females it ranges from 48.4 in RG1 to 0.6 in RG4. In males, AP in RGs from 1 to 3 is over 65%, in RG4 is 59%, in RG5 is 30%, in RG6 is -14%. AP in females gradually drops from 95% in RG1 to -64% in RG6.the burden of mesothelioma in populations residing in NPCSs is high, with an AP gradient consistent with the a priori RG. This burden impacts on females in a different way: rates are lower than male ones; AP is similar to male ones in the RGs 1 and 3.

The purpose of the SENTIERI-ReNaM Project is to analyse the incidence of mesothelioma in Italian National Priority Contaminated Sites (NPCSs) in order to estimate the health impact of asbestos on resident populations, disentangling the role of occupational and environmental exposures. SENTIERI Project has provided the relevant information on geographic and demographic structure of NPCSs and on existing sources of contamination. The Italian National Mesothelioma Registry (ReNaM), that covers the whole country through its Regional Operational Centres (CORs), has made available the procedures for estimating the incidence of mesothelioma in NPCSs and for assessing occupational and environmental asbestos exposure of the individual cases. The synergy between these two epidemiological surveillance systems lay also the ground for communication programmes with the affected communities.

Background: Metabolic disorders are known to alter the mechanical properties of tendons. We sought to evaluate the prevalence of asymptomatic Achilles tendon enthesopathic changes in patients with type 2 diabetes mellitus (T2DM) without peripheral neuropathy. Methods: We recruited 43 patients with T2DM and 40 controls. Neuropathy was excluded with the Michigan Neuropathy Scoring Instrument. Bilateral ultrasonography of the Achilles tendon enthesis was performed. Results: Patients with T2DM had a higher prevalence of hypoechogenicity (26.7% versus 2.5%; P = .0001), entheseal thickening (24.4% versus 8.7%; P = .007), and enthesophytes (74.4% versus 57.5%; P = .02). No differences were found in the number of patients with erosions (1.2% versus 0%; P > .99), cortical irregularities (11.6% versus 3.7%; P = .09), bursitis (5.8% versus 3.7%; P = .72), or tears (2.3% versus 1.2%; P > .99). The mean ± SD sum of abnormalities was higher in patients with T2DM (1.5 ± 1.1 versus 0.7 ± 0.6; P < .0001), as was the percentage of bilateral involvement (72.1% versus 45.0%; P = .01). Mean ± SD thickness did not differ between patients and controls (4.4 ± 1.1 mm versus 4.2 ± 0.8 mm; P = .07). Conclusions: According to our data, there is an elevated prevalence of asymptomatic Achilles tendon enthesopathic changes in patients with T2DM independent of peripheral neuropathy.

In the last years, an increasing interest in molecular imaging has been raised by the extending potential of positron emission tomography [PET]. The role of PET imaging, originally confined to the oncology setting, is continuously extending thanks to the development of novel radiopharmaceutical and to the implementation of hybrid imaging techniques, where PET scans are combined with computed tomography [CT] or magnetic resonance imaging[MRI] in order to improve spatial resolution. Early preclinical studies suggested that 18F–FDG PET can detect neuroinflammation; new developing radiopharmaceuticals targeting more specifically inflammation-related molecules are moving in this direction. Neurological involvement is a distinct feature of various systemic autoimmune diseases, i.e. Systemic Lupus Erythematosus [SLE] or Behcet’s disease [BD]. Although MRI is largely considered the gold-standard imaging technique for the detection of Central Nervous System [CNS] involvement in these disorders. Several patients complain of neuropsychiatric symptoms [headache, epilepsy, anxiety or depression] in the absence of any significant MRI finding; in such patients the diagnosis relies mainly on clinical examination and often the role of the disease process versus iatrogenic or reactive forms is doubtful. The aim of this review is to explore the state-of-the-art for the role of PET imaging in CNS involvement in systemic rheumatic diseases. In addition, we explore the potential role of emerging radiopharmaceutical and their possible application in aiding the diagnosis of CNS involvement in systemic autoimmune diseases.

The cohort study aims to test the hypothesis of an association between specific exposure/s and adverse health outcomes. The cohorts include the subjects who experience the exposure/s and are followed up over time to ascertain the health outcomes. This contribution presents the database for the analysis of mortality studies which is made available for public institutions carrying out cohort studies in Italy. The rates were computed from official mortality data from ISTAT. The database contains 141 causes or groups of causes for the years 1970-2012 ensuring correspondence with subsequent editions of ICD (International Classification of Diseases) VIII, IX and X.

The territory around the industrial Sicilian area of Priolo, Italy, has been defined as a contaminated site (CS) of national priority for remediation because of diffuse environmental contamination caused by large industrial settlements. The present study investigates the spatial distribution of cancer into the CS territory (period 1999-2006). Different geographical methods used for the evaluation of the impact of industrial air pollutants were adopted. Using the database of Syracuse Province Cancer Registry, gender-specific standardised incidence ratios were calculated for 35 tumour sites for the CS overall and for each municipality included in the CS. A cluster analysis for 17 selected neoplasms was performed at micro-geographical level. The identification of the priority index contaminants (PICs) present in environmental matrices and a review of their carcinogenicity have been performed and applied in the interpretation of the findings. The area has a higher cancer incidence with respect to the provincial population, in particular excess is registered among both genders of lung, bladder and breast cancers as well as skin melanoma and pleural mesothelioma and there is an a priori evidence of association with the exposure to PICs. The study highlights the need to provide different approaches in CSs where several exposure pathways might be relevant for the population. The presence of potential sources of asbestos exposure deserves specific concern.

Objectives To evaluate the correlation between inflammatory measures and whole-body insulin sensitivity in psoriatic arthritis (PsA) patients. Methods For the present study, 40 nondiabetic PsA patients were recruited. A standard oral glucose tolerance test (OGTT) was performed. The insulin sensitivity index (ISI), insulinogenic index (IGI) and oral disposition index (ODI) were calculated from dynamic values of glucose and insulin obtained during OGTT. Results In our study population, mean ISI was 3.5 ± 2.5, median IGI was 1.2 (0.7–1.8), mean ODI 4.5 ± 4.5. In univariate correlation analysis, ISI correlated inversely with systolic blood pressure (sBP) (R = -0.52, p = 0.001), diastolic blood pressure (dBP) (R = -0.45, p = 0.004) and complement C3 (R = -0.43, p = 0.006) and ODI correlated inversely with sBP (R = -0.38, p = 0.02), dBP (R = -0.35, p = 0.03) and complement C3 (R = -0.37, p = 0.02). No significant correlations were found between analyzed variables and IGI. In a stepwise multiple regression, only complement C3 entered in the regression equation and accounted for approximately 50% of the variance of ISI. Using a receiver operating characteristic (ROC) curve we identified the best cut-off for complement C3 of 1.32 g/L that yielded a sensitivity of 56% and a specificity of 96% for classification of insulin resistant patients. Conclusions In conclusion, our data suggest that serum complement C3 could represent a useful marker of whole-body insulin sensitivity in PsA patients.

Rheumatoid arthritis (RA) is a chronic inflammatory disease characterized by an excess of cardiovascular disease (CVD) risk, estimated to be at least 50% greater when compared to the general population. Although the widespread diffusion of type 2 diabetes mellitus (T2DM) awareness, there is still a significant proportion of patients with T2DM that remain undiagnosed. Aim of this cross-sectional study was to evaluate the prevalence of undiagnosed diabetes and prediabetes in RA patients. For the present study, 100 consecutive nondiabetic RA patients were recruited. Age- and sex-matched subjects with noninflammatory diseases (osteoarthritis or fibromyalgia) were used as controls. After overnight fasting, blood samples were obtained for laboratory evaluation including serum glucose, total cholesterol, high-density lipoprotein (HDL)-cholesterol, low-density lipoprotein (LDL)-cholesterol, triglycerides, uric acid, erythrocyte sedimentation rate (ESR), high sensitivity C-reactive protein (hs-CRP), rheumatoid factor (RF), and anti-Cyclic Citrullinated Peptide Antibodies (ACPA). A standard Oral Glucose Tolerance Test (OGTT) with 75 g of glucose was performed and blood samples were collected at time 0, 30, 60, 90, and 120 minutes, for measurement of plasma glucose concentrations. The prevalence of impaired fasting glucose (IFG) (9/100 vs 12/100, P = 0.49), impaired glucose tolerance (IGT) (19/100 vs 12/100, P = 0.17), and concomitant IFG/IGT (5/100 vs 9/100, P = 0.27) was similar between groups, whereas the prevalence of diabetes was significantly higher in RA patients (10/100 vs 2/100, P = 0.02). In a logistic regression analysis, increasing age (OR = 1.13, 95% CI 1.028–1.245, P = 0.01) and disease duration (OR = 1.90, 95% CI 1.210–2.995, P = 0.005) were both associated with an increased likelihood of being classified as prediabetes (i.e. IFG and/or IGT) or T2DM. A ROC curve was built to evaluate the predictivity of disease duration on the likelihood of being diagnosed with T2DM. The area under the ROC curve was 0.67 (95% CI: 0.56–0.78, P = 0.004). We identified the best cut-off of 33 months that yielded a sensitivity of 61% and a specificity of 70% for classification of T2DM patients. According to our data, RA seems to be characterized by an elevated prevalence of undiagnosed diabetes, especially in patients with longer disease duration.

INTRODUCTION: Spatial distribution of mortality from pleural mesothelioma (which in the ICD-10 Revision has a specific code: C45.0) in Italy for the period 2003-2009 is described. Previous mortality studies at national level employed the topographic code "Malignant neoplasms of pleura", because of unavailability of a specific code in ICD-9 Revision for pleural mesothelioma. METHODS: Standardized mortality ratios were computed for all municipalities, using each regional population as reference; for municipalities in Regions with rate higher than the national rate, the latter has been used as reference. SMRs were computed specifically also for each Italian Polluted Sites "of national concern for environmental remediation" (IPS) with asbestos exposure sources, composed by one or more municipalities, using regional rate as reference. Spatial Scan Statistics procedure, using SatScan software, was applied in cluster analysis: the country was divided into geographic macro-areas and the relative risks (RR) express the ratio of risk within the cluster to the risk of the macro-area outside the cluster. Clusters with p-value < 0.10 were selected. RESULTS: The national standardized annual mortality rate was 1.7 cases per 100 000. Several areas with evident burden of asbestos-related disease were detected. Significant clusters were found in correspondence to asbestos-cement industries (e.g. Casale Monferrato, women: RR = 28.7), shipyards (e.g. Trieste, men: RR = 4.8), petrochemical industries (e.g. Priolo, men: RR = 6.9) and a stone quarry contaminated by fluoro-edenite fibres (Biancavilla, women: RR = 25.9). Some of the increased clusters correspond to IPS. CONCLUSIONS: The results may contribute to detect asbestos exposure and to set priorites for environmental remediation.

Background An epidemic of asbestos-related diseases is ongoing worldwide. Mortality from malignant pleural neoplasms in Italy was analyzed, to estimate the health impact of asbestos at national and local level. Methods Mortality from ICD-9 code 163 was considered, in the time-window 1995–2002, using National Bureau of Statistics data. National and regional standardized rates and municipal Standardized Mortality Ratios (SMR) were calculated. Municipal clusters were identified by applying Spatial Scan Statistics procedure. Relative risks (RR) express the ratio of risk within the cluster to the risk outside the cluster. Results The national standardized annual mortality rate was 1.9 per 100,000. Significant clusters corresponded to asbestos-cement industries (Casale Monferrato: RR = 11.63), shipyards (Monfalcone, RR = 7.43), oil refineries (Falconara, RR = 2.52), petrochemical industries (Priolo, RR = 3.81). Conclusions The present study confirms malignant pleural neoplasms mortality as a suitable indicator of asbestos exposure at geographic level. In addition to asbestos-cement industries and shipyards, other industrial settings are associated with pleural neoplasm mortality. Am. J. Ind. Med. 55:11–24, 2012. © 2011 Wiley Periodicals, Inc.

Rheumatoid arthritis (RA) is characterized by increased insulin resistance, a well-known risk factor for diabetes and cardiovascular diseases. The aim of the present study was to evaluate the effect of abatacept on insulin sensitivity in RA patients with moderate to severe disease despite treatment with methotrexate. Fifteen RA patients were recruited for the present study. Patients were evaluated at time 0 and after 6 months of the treatment with i.v. abatacept at the dosage recommended for weight range. Evaluation included oral glucose tolerance test (OGTT) at both time points. Insulin sensitivity was estimated with insulin sensitivity index (ISI) by Matsuda, a measure of whole-body insulin sensitivity. ISI significantly increased after the treatment with abatacept from 3.7 ± 2.6 to 5.0 ± 3.2 (P = 0.003) with a mean difference of 1.23. Analysis of glucose and insulin values during OGTT revealed a reduction of both glucose (303.9 ± 73.4 mg/dL min versus 269.2 ± 69.5 mg/dL min, P = 0.009) and insulin (208.4 ± 119.7 mg/dL min versus 158.0 ± 95.3 mg/dL min, P = 0.01) area under the curves (AUCs). Accordingly also glycated hemoglobin significantly improved (5.5 ± 0.4% versus 5.3 ± 0.3%, P = 0.04). No significant differences were found for measures of β-cell function insulinogenic index (1.11 ± 1.19 versus 1.32 ± 0.82, P = 0.77) and oral disposition index (2.0 ± 5.4 versus 6.0 ± 6.0, P = 0.25). Treatment with abatacept seems to be able to improve whole-body insulin sensitivity in RA patients without affecting β-cell function.

Subsequent to the detection of a cluster of mesothelioma cases in the Sicilian town of Biancavilla, located at the slopes of Etna volcano, ad hoc epidemiological studies and environmental monitoring suggested an etiological role of an asbestiform fiber present in a stone quarry. The fiber was shown to constitute a new mineral species named fluoro-edenite. Fluoro-edenitic fibers were found in the materials extracted from the quarry and used in the local building industry, as well as in soils. Besides the risk of mesothelioma, residents in Biancavilla showed a significantly increased mortality from chronic obstructive pulmonary disease, which was particularly evident among women. In the light of these findings, Biancavilla was defined a site of national interest for environmental reclamation. The first preventive action involved termination of quarrying activity, covering with asphalt of roads previously paved with local soil materials, and removal of sources of dust in the urban area. Concurrent to the implementation of environmental cleanup, some specific "second generation" studies are now being designed and performed, namely morbidity surveys based on hospital discharge cards, monitoring of fibers in sputum and health surveillance in selected population groups. In this frame, special emphasis is given to the issue of communication, both to the general public and to target groups like family doctors, teachers, and media professionals. This experience could represent a useful basis for the elaboration of a strategy to approach similar environmental issues.

Background and history: Italy was the main asbestos producer and one of the greatest consumers in 20th century Europe until the asbestos ban was introduced in 1992. Asbestos exposure affected the population in a wide range of working environments, namely mining and marketing of asbestos, asbestos cement production, shipyards and textile industries. This also determined a widespread environmental asbestos exposure affecting the surrounding communities. Methods: To investigate the drivers and difficulties of the process leading to the asbestos ban and its subsequent implementation, we focused on stakeholder involvement, environmental health policies, capacity building and communication. Results: In the past three decades, stakeholder involvement has been instrumental in advancing the industrial asbestos replacement process, prevention and remediation interventions. Furthermore, involvement also contributed to the integration of environmental and health policies at national, regional and local levels, including capacity building and communication. In a global public health perspective, international scientific cooperation has been established with countries using and producing asbestos. Discussion and Conclusions: Key factors and lessons learnt in Italy from both successful and ineffective asbestos policies are described to support the relevant stakeholders in countries still using asbestos contributing to the termination of its use.

Background Aim of this study was to evaluate the prevalence of plantar fascia (PF) enthesopathy in Type 2 diabetes mellitus (T2DM) patients without distal peripheral neuropathy (DPN). Methods We recruited 50 T2DM patients without DPN and 50 healthy controls. DPN was excluded using the Michigan Neuropathy Screening Instrument (MNSI). All patients underwent a bilateral sonographicevaluation of the enthesealportion of the PF. Results PF thickness was significantly higher in T2DM patients (p

In a recent epidemiological study, researchers investigated mortality from malignant pleural neoplasms in Italy, and they detected some geographic clusters of cases of this disease. We found a town located in a volcanic area of eastern Sicily to be of special interest. The residents, some of whom were diagnosed with pleural mesothelioma, had never had any relevant exposure to asbestos during their professional lives. The results of an environmental survey suggested that a possible cause of asbestos exposure was the stone quarries near the town. The products of the quarries contain fibrous amphiboles, which are used widely in the local building industry. These fibrous amphiboles were identified as intermediate phases between tremolite and actinolite. Samples were collected from buildings in the town, and concentrations of amphibole fibers were evaluated. Fibrous phases were detected in 71% of the samples, and fiber concentrations ranged from a few thousand to more than 4 x 10(4) fibers/mg of material. In addition, we conducted a study on the mineral fiber lung burden in a pleural mesothelioma case. Many mineral fibers that were classified as the same tremolite-actinolite fibrous amphibole found in the quarries and in the building materials were detected in the lung tissue. The results suggest that the inhabitants of the town we studied had been exposed for several decades to asbestos fibers that were present in the material extracted from the local stone quarries. The material was subsequently used in the building industry, and this has caused an increased risk of pleural mesothelioma in the area.

Background Rheumatic diseases associate with metabolic and cardiovascular disorders [1]. These complications might be a side effect of drugs exposure (i.e. corticosteroids) but also a direct consequence of the widespread systemic inflammation. While the association between inflammatory markers and metabolic disturbance has been extensively explored, few data are available about liver involvement in inflammatory arthritis [2]. Objectives To explore possible association between inflammatory markers and serum indicators of non-alcoholic fatty liver disease (NAFLD) in a sample of unselected inflammatory arthritis subjects. The liver fat score (LFS) and the hepatic steatosis index (HSI) were employed as serum NAFLD markers [3]. Methods Subjects who met ACR/EULAR criteria for rheumatoid arthiritis (RA), CASPAR criteria for psoriatic arthritis (PsA) and ESSG criteria for undifferentiated spondiloarthritis (uSPA) were consecutively recruited for the present investigation. After overnight fasting, the following serum analytes were determined: blood glucose, lipids, insulin, complete blood count, erythrocyte sedimentation rate (ESR), high sensitivity C-Reactive Protein (hsCRP). LFS was calculated with the formula: -2.79 + 1.18 * Metabolic Syndrome (yes=1/no=0) + 0.45 * Type 2 Diabetes (yes=2/no=0) + 0.15 * Insulin + 0.04 * AST - 0.94 * AST/ALT. HIS was calculated with the formula: 8 * ALT/AST + BMI +2, if DM2; +2, if females. Metabolic syndrome was defined according to the criteria of the International Diabetes Federation. Pearson9s or Spearman9s correlation analyses were used as appropriate to test the associations between continuous variables. Not normally distributed variables were log-transformed before analysis. Results Overall, a total of 55 subjects (27 AR, 18 PsA and 10 uSPA) were recruited. The prevalence of female gender was 60%. The mean age was 53.5±9.8. Twenty-four patients were under stable treatment with methotrexate (MTX). In simple correlation analyses, LFS significantly correlated with ESR (r=0.37, p Conclusions The results of the present study, although conducted in a limited sample, demonstrated an interesting association between liver fat indices and inflammatory markers. Our data, if confirmed in other population, might add important information about the relationship linking metabolic complications and rheumatic diseases.
