Prevention from Sharp Injuries in the Hospital Sector: An Italian National Observatory on the Implementation of the Council Directive 2010/32/EU before and during the COVID-19 Pandemic.

Sharp injuries, determining the risk of bloodborne infections and psychological distress in healthcare workers, may be prevented by a set of strategies, legally enforced in Europe through the Directive 2010/32/EU. To assess its level of implementation in Italy, a national survey was conducted in 2017 and again in 2021, evaluating the progress and possible drawbacks of the COVID-19 pandemic. Altogether, 285 safety managers and 330 nurses from a representative sample of 97 and 117 public hospitals were interviewed using a standardized questionnaire. Knowledge of the Directive requirements decreased significantly, with <60% of participants answering correctly in 2021, and nurses' attendance in specific courses dropped to 25% in 2021 compared to 54% in 2017. Over 75% of hospitals introduced multiple safety-engineered devices (SED), though total replacement occurred in <50% of cases; routine SED availability increased for blood collection (89%) and venous access devices (83%). Incorrect behaviors in handling sharps decreased significantly over time. Nurses' HBV vaccination coverage was high (89% in both surveys); in the last year, 97% were vaccinated against COVID, and 47% against influenza. Average annual injuries per hospital did not increase significantly (32 in 2021 vs. 26 in 2017). In 2017, nurses' perceived safety barriers were working in emergency situations (49%) and lack of resources (40%); in 2021, understaffing (73%), physical fatigue (62%), and handling difficulties while wearing full protective equipment (59%). Safety measures were implemented in Italian hospitals, and although the average injuries per hospital did not show a decrease, these measures could have helped protect healthcare workers during the pandemic, mitigating its potential impact on the increase in situations at risk of injury.

Medium-term effect of sublingual l-glutathione supplementation on flow-mediated dilation in subjects with cardiovascular risk factors.

OBJECTIVE: Supplementation of glutathione (GSH) may be a positive strategy to improve the endogenous antioxidant defense required to counteract many acute and chronic diseases. However, the efficacy of GSH treatment seems to be closely related to type of administration, degree of absorption, and increase of its concentrations. The aim of this study was to test a new sublingual formulation of L-GSH, which enters directly the systemic circulation, to assess its efficacy on circulating biochemical markers of hepatic metabolism, lipid profile, and oxidative stress and on peripheral vascular function compared with placebo in patients with cardiovascular risk factors (CVRF). METHODS: We enrolled 16 healthy men with CVRF in a double-blinded, randomized placebo-controlled crossover study. At each visit, blood samples were collected for biochemistry analyses and peripheral endothelial function (reactive hyperemia index [RHI]) and stiffness were measured by Endo-PAT2000. RESULTS: In the overall population, a decrease in total and low-density lipoprotein cholesterol was highlighted after L-GSH supplementation compared with placebo (P = 0.023 and P = 0.04, respectively). On the contrary, no difference was observed in RHI and oxidative stress markers between L-GSH and placebo in the study population. However, seven participants with baseline abnormal RHI (≤1.67) compared with those with normal RHI showed a significant reduction of arterial stiffness after L-GSH administration, (P = 0.007 and P = 0.037, respectively). CONCLUSIONS: Supplementation of L-GSH compared with placebo influences the lipid profile of patients with CVRF. Sublingual L-GSH may represent a valid prevention of vascular damage in patients with CVRF and endothelial dysfunction.

[Update on the subject of epidemiology of blood-transmitted occupational infections]. / Aggiornamenti in tema di epidemiologia delle malattie infettive occupazionali trasmesse per via ematica.

Healthcare workers (HCW) are exposed to many different pathogens, and cases of occupational infection have been reported involving the vast majority of known and emerging agents. The risk is present during all the phases of patient care and manipulation of biologic materials, and the implementation of Standard Precautions--and biosafety level 2 measures in the laboratory--and Transmission-Based Precautions in all health settings represents the necessary preventive intervention required by law. Percutaneous exposures represent an extremely frequent event in healthcare facilities; among the many pathogens acquired through this type of exposure, those of highest concern due to the frequency of exposure are HIV, HBV and HCV. Over the last 10 years, though the risk of exposure is still not negligible, occupational infection with HBV has become a rare event; conversely, the incidence of acute C hepatitis became significantly higher among HCW (1,6 per 100.000 inhabitants) with respect to the general population (0,6), with a seroconversion rate following an occupational exposure between 0,5% and 1,8%; finally, reports of occupational HIV infection have decreased, probably also as a secondary beneficial effect of antiretroviral treatment in patients and post-exposure prophylaxis in HCW. The Studio Italiano Rischio Occupazionale da HIV (SIROH) documented from 1986 to 2009 one occupational HBV case, 6 HIV cases (the last one in 2007) and 32 HCV cases. In Europe, the Directive 2010/32/EU approved on May 10 2010 requires Member State to implement within three years a global strategy to prevent occupational exposures in the healthcare setting, particularly with respect to needlestick and sharp injuries, including the adoption, based on risk assessment, of devices incorporating safety features. In Italy the introduction of these devices, according to data collected by the SIROH, showed the possibility to decrease percutaneous exposures by 75%, an effect sustained over time if supported by information, education and training.
