Decade-long insights: tracking asbestos-related health impacts among formerly exposed workers in Palermo, Italy.

Background: Asbestos is a foremost occupational carcinogen globally. Despite the prohibition under Law 257/1992, Italy persists as one of the European nations most burdened by asbestos-related diseases (ARDs). This research assessed ARD cases in asbestosexposed workers from the Province of Palermo, Italy, spanning 2010-2021. Methods: Data acquisition utilized the epidemiological dataset from the 'Service of Prevention and Safety on Work Environment' under the Prevention Department of Palermo's Local Health Authority (LHA). Results: Between 2010 and 2021, we identified 245 ARD instances, comprising 163 Asbestosis/Pleural plaques, 41 Lung Cancers, 38 Mesotheliomas, and 3 unspecified cases. Multivariate analysis indicated a notable decline in temporal exposure for mesothelioma (HR=0.933; 95% CI=0.902-0.965) and lung cancer (HR=0.93; 95% CI=0.90-0.978) relative to pleural plaques/asbestosis. Tobacco use displayed a pronounced correlation with lung cancer (smoker HR=64.520 95% CI=13,075-318.390; former smoker HR=20.917 95% CI=4,913-89.048). A significant link was observed between mesothelioma and pleural plaques/asbestosis in those employed in shipbuilding and repair (HR=0.371 95% CI=0.155-0.892). Conclusions: ARDs persist in clinical observations, even following the 1992 cessation of asbestos-related activities, emphasizing an enduring public health challenge. Enhancing prevention strategies is paramount, focusing on amplifying anamnestic and occupational data collection, thereby facilitating superior early diagnosis strategies for these maladies in the occupationally exposed cohort.

Prevalence of smoking habits, attitudes and knowledge on counteractive strategies among a sample of healthcare employees: results of the smoking-free health environments project in the province of Palermo, Italy.

Introduction: Tobacco use is responsible for over 7 million deaths annually, making smoking the leading cause of preventable mortality globally. Over the last two decades in Italy, the prevalence of smoking among physicians has consistently decreased, while it remains higher and is gradually decreasing among non-physician healthcare workers. The aim of this study was to investigate the Prevalence of smoking habits, attitudes, and knowledge on counteractive strategies among employees in the Primary Healthcare Facilities in the Province of Palermo, Italy. Methods: A cross-sectional survey was conducted between June 2020 and December 2020 through a previously validated anonymous questionnaire structured in four sections including 34 items. Data were analyzed using Stata/MP 12.1 statistical software. Results: Overall, 2,645 participants answered the questionnaire. The prevalence of either current or former smokers was 18.6%. Based on the multivariable analysis conducted, a significantly higher frequency of current smokers was observed among male participants (AdjOR: 1.29; CI95%: 1.02-1.64) and those belonging to the Surgical Unit (AdjOR: 1.92; CI95%: 1.27-2.90). Conversely, the prevalence of current smokers was significantly lower among those with at least one child (AdjOR: 0.67; CI95%: 0.49-0.91), with an educational qualification equal to or greater than a graduation degree (AdjOR: 0.56; CI95%: 0.43-0.73), those who considered second-hand smoke harmful (AdjOR: 0.06; CI95%: 0.008-0.60), those who had observed smoking or detected the smell of smoke in their workplace (AdjOR: 0.64; CI95%: 0.45-0.91). Furthermore, the prevalence of current smokers was significantly lower among participants who believed that healthcare professionals could play a crucial role in influencing their patients' lifestyles (AdjOR: 0.67; CI95%: 0.50-0.90) and among those who recommend their patients to quit smoking (AdjOR: 0.35; CI95%: 0.24-0.51). Discussion: The results of the current research demonstrate that, despite the decline in smoking prevalence among physicians, the rate of smokers among healthcare facility employees remains unacceptably high. This underscores the need to re-evaluate current anti-tobacco strategies in the workplace.

Screening for synthetic cannabinoids in hair by using LC-QTOF MS: a new and powerful approach to study the penetration of these new psychoactive substances in the population.

The current analytical technology for the determination of New Psychoactive Substances in biological samples is still largely inadequate, because the immunoassays are unsuitable for the detection of most of these compounds and the use of traditional gas chromatography-mass spectrometry techniques is hampered by the lack of chromatographic standards and mass fragmentation patterns. Taking advantage of the molecular recognition capability of high-resolution mass spectrometry, the present work aimed to apply liquid chromatography-quadrupole-time of flight mass spectrometry for the rapid identification of New Psychoactive Substances in the hair, a peculiar tissue which "keeps memory" of the recent history of drug intake of the subject. All the samples were screened for the presence of 50 different New Psychoactive Substances (synthetic cannabinoids, cathinones and phenethylamines), substances that had been reported officially by the National Early Warning System in the period 2009-2011. Among the 435 samples analyzed, 8 were found "positive" for the following compounds: JWH-018, JWH-073, JWH-081, JWH-250, JWH-122, in a broad range of concentrations (0.010-1.28 ng/mg). Results strongly support the use of hair analysis to monitor the diffusion of new psychoactive drugs in the community.

Analysis of appeals against the ruling of occupational physicians lodged with the Prevention and Occupational Epidemiology Operative Unit, ASP Palermo (Palermo Health Authority), from 2008-2010.

INTRODUCTION: The responsibility of the Department for Prevention and Safety at the workplace of the Palermo Health Authority (ASP) is to monitor and coordinate the activity of occupational physicians operating in Palermo and its province. One of its obligations is to examine appeals "against the judgment of occupational physicians", "..and, after carrying out further investigation, confirm, modify or reverse the ruling itself" (art. 41, par. 6, legislative Decree 81/08). OBJECTIVES: The purpose of this study was to analyze the appeals lodged against a judgment of fitness for work" submitted to the "Health Prevention and Occupational Epidemiology Operative Unit" of the Department of Prevention and Safety at the Workplace of the ASP Palermo, from 2008 to 2010. METHODS: The total number of appeals lodged during the three-year period was 211, 174 of which were finalized. RESULTS: The most frequent job category among the appellants was that of blue-collar workers, in various sectors, covering 44.5% of the subjects under study (93 cases). In 64.2% of the processed appeals (131 cases), the judgment of the physician was modified, while in the remaining 36.8% (73 cases) it was confirmed. The work fitness judgment with restrictions was the category against which most appeals were lodged, and the diseases in question mostly concerned the osteoarticular and cardiovascular systems. CONCLUSION: In a context of continuous change in the labour field and the related risks to the health and safety of workers, the occupational physician must approach the worker in a comprehensive manner, through an assessment of the possible health problems and the working environment in which he/she operates.

Micellar electrokinetic chromatography: a new simple tool for the analysis of synthetic cannabinoids in herbal blends and for the rapid estimation of their logP values.

For the first time a capillary separation based on micellar electrokinetic chromatography (MEKC) with diode array detection (DAD) was developed and validated for the rapid determination of synthetic cannabinoids in herbal blends. Separations were carried out on a 30 µm(ID) × 40 cm uncoated fused silica capillaries. The optimized buffer electrolyte was composed of 25 mM sodium tetraborate pH 8.0, 30 mM SDS and n-propanol 20% (v/v). Separations were performed at 30 kV. Sample injection conditions were 0.5 psi, 10s. Diazepam and JWH-015 were used as internal standards. The determination of the analytes was based on the UV signal recorded at 220 nm, corresponding to the maximum wavelength of absorbance of the molecules, whereas peak identification and purity check were also performed on the basis of the acquisition of UV spectra between 200 and 400 nm wavelengths. Under the described conditions, the separation of the compounds was achieved in 25 min without any significant interference from the matrix. Linearity was assessed within a concentration range from 5 to 100 µg/mL. The intra-day and inter-day imprecision values were below 2.45% for relative migration times and below 10.75% for relative peak areas. The present method was successfully applied to the direct determination of synthetic cannabinoids in 15 different herbal blend samples requiring only sample dilution. In addition, the developed MEKC separation was also applied to estimate the octanol/water partition coefficients (logP) of these new and poorly known molecules.

[Asbestos-related diseases observed in Palermo (Italy) among workers exposed to asbestos]. / Patologie asbesto-correlate osservate a Palermo e Provincia tra lavoratori esposti ad amianto.

The aim of this study was to evaluate cases of asbestos-related diseases in workers exposed to asbestos in the province of Palermo (Italy) from 2005 to 2009. Data were collected from medical records and from reports from the Prevention and Safety in the Workplace Unit of the provincial health authorities of and between Palermo. Multinomial logistic regression showed a significant association between tobacco smoke and lung cancer and between starting work at an early stage and presence of asbestosis and pleural plaques. Results confirm that over eighteen years after the entry into force of Law 257/1992, which established the cessation of all activities related to asbestos, asbestos-related diseases continue being observed in clinical practice and represent a serious public health problem.
