Violence against health workers: findings from three emergency departments in the teaching hospital of Padua, Italy

Emergency departments (EDs) are high-risk places for Workplace Violence (WPV). In Italy, this phenomenon is scarcely investigated. The aim of this study is to evaluate the incidence, experiencing and perception of WPV in the general ED (GED), paediatric ED (PED) and obstetric-gynaecological ED (OGED) of the teaching hospital Azienda Ospedaliera in Padua (AOP). We led a cross-sectional study among the GED, OGED and PED staffs, submitting an anonymous questionnaire, regarding personal information, verbal and physical aggression experiences, risk factors and proposals for corrective actions. Our sample consists of 73 people from GED, 45 from OGED and 53 from PED. Aggressions are common. Verbal aggressions are almost never recorded, even in the case of physical aggressions, 41% did not signal the event. Both in GED and in OGED, most of the staff (68.9% and 75.0%, respectively) underwent aggression by neither psychiatric nor substance abuser patients (PSAPs). Physical aggressions are more common in GED than in OGED and in PED; most of professionals were assaulted by PSAPs. In all EDs, verbal or physical assault has been lived through by anger, resignation or fear, rarely by indifference. Professionals think there are structural characteristics and risk factors that could be corrected. They do not know how to manage assaults and would deem it useful training meetings with experts. Our results regarding how staff perceive and experience violence in the ED concern a local situation, that nevertheless reflect current evidence about the topic of WPV which plagues EDs across the globe

Physico-chemical properties of quartz from industrial manufacturing and its cytotoxic effects on alveolar macrophages: The case of green sand mould casting for iron production

Industrial processing of materials containing quartz induces physico-chemical modifications that contribute to the variability of quartz hazard in different plants. Here, modifications affecting a quartz-rich sand during cast iron production, have been investigated. Composition, morphology, presence of radicals associated to quartz and reactivity in free radical generation were studied on a raw sand and on a dust recovered after mould dismantling. Additionally, cytotoxicity of the processed dust and ROS and NO generation were evaluated on MH-S macrophages. Particle morphology and size were marginally affected by casting processing, which caused only a slight increase of the amount of respirable fraction. The raw sand was able to catalyze \u2022OH and CO2\u2022\u2013 generation in cell-free test, even if in a lesser extent than the reference quartz (Min-U-Sil), and shows hAl radicals, conventionally found in any quartz-bearing raw materials. Enrichment in iron and extensive coverage with amorphous carbon were observed during processing. They likely contributed, respectively, to increasing the ability of processed dust to release CO2\u2022\u2013and to suppressing \u2022OH generation respect to the raw sand. Carbon coverage and repeated thermal treatments during industrial processing also caused annealing of radiogenic hAl defects. Finally, no cellular responses were observed with the respirable fraction of the processed powder.
