COVID-19 Vaccination and Medical Liability: An International Perspective in 18 Countries

The COVID-19 vaccination has proven to be the most effective prevention measure, reducing deaths and hospitalizations and allowing, in combination with non-pharmacological interventions, the pandemic to be tackled. Although most of the adverse reactions to vaccination present mild symptoms and serious effects are very rare, they can be the cause of legal action against the healthcare workers (HCWs) who administered it. To highlight differences in the medical liability systems, we performed a search for the three most populous countries in each continent on vaccine injury compensation programs, new laws or policies to protect HCWs administering vaccinations introduced during the COVID-19 pandemic, and policies on mandatory vaccinations, on literature databases and institutional sites. We found that in seven countries the medical liability system is based on Common Law, while in eleven it is mainly based on Civil Law. Considering the application of specific laws to protect HCWs who vaccinate during the pandemic, only the USA and Canada provided immunity from liability. Among the countries we analyzed, fourteen have adopted compensation funds. From an international perspective, our results highlight that in eleven (61.1%) countries medical liability is mainly based on Civil Law, whilst in seven (38.9%) it is based on Common Law

In vitro comparative study on the mechanical behavior of Zirconia and Polyetheretherketone in applied dental sciences

OBJECTIVE: Recently, Zirconia and polyaryletherketone (PEEK) have attracted increasing interest as reliable and safe materials in dental applications, mainly because of their good biomechanical characteristics. The aim of this study was to investigate the response to different loads by prosthetic frameworks for supported fixed partial dentures (FPDs), thus simulating osseointegrated implants. MATERIALS AND METHODS: The specimens were divided into two groups (n= 5 each). Group A: FDPs in zirconia-ceramic; Group B: FDPs in PEEK-composite. These 2 groups were subjected to vertical loads so to evaluate structural deformation; then, they have been analyzed by scanning electron microscopy (SEM) at different magnifications. RESULTS: In tested samples, different types of mechanical failures have been observed. In Zirconia-specimens, chipping is the main failure noticed in this study, mostly in distal margins of the structure. Also, peek-specimens show failure and fracture. CONCLUSIONS: Zirconia and PEEK could be considered both good materials, but several investigations are needed to use these materials as an alternative to metals for fixed partial dentures

Implications of MMP9 for Blood Brain Barrier Disruption and Hemorrhagic Transformation Following Ischemic Stroke.

Numerous studies have documented increases in matrix metalloproteinases (MMPs), specifically MMP-9 levels following stroke, with such perturbations associated with disruption of the blood brain barrier (BBB), increased risk of hemorrhagic complications, and worsened outcome. Despite this, controversy remains as to which cells release MMP-9 at the normal and pathological BBB, with even less clarity in the context of stroke. This may be further complicated by the influence of tissue plasminogen activator (tPA) treatment. The aim of the present review is to examine the relationship between neutrophils, MMP-9 and tPA following ischemic stroke to elucidate which cells are responsible for the increases in MMP-9 and resultant barrier changes and hemorrhage observed following stroke

A new tool to evaluate burnout: the Italian version of the BAT for Italian healthcare workers

Background: Healthcare workers (HCWs) represents one of the highest-risk population to develop burnout symptoms. Recently, a new tool has been designed to measure several dimensions that capture an exhaustive expression of burnout symptoms by six dimensions (i.e., exhaustion; mental distance; cognitive impairment; emotional impairment; psychological distress; psychosomatic complaints). Methods: The current study aims to adapt the Burnout Assessment Tool (BAT) to an Italian Healthcare workers’ sample confirming the original second-order factorial structure. Furthermore, we expected to find good indexes of reliability and validity tests. Participants were 697 Italian Health Care Workers (Female = 68.44%; mean age = 36.47; SD = 11.20). Data were collected by self-report questionnaires submitted by the snowball method. Results: Findings show a good fit of the BAT’s structure, confirming the hypothesized second-order factorial model. Furthermore, good reliability has been established with the study’s measures. Conclusions: The BAT for HCWs is eligible as a new tool to evaluate burnout in the at-risk HCWs as a multi-facet constellation of symptoms

The Dermatological Effects and Occupational Impacts of Personal Protective Equipment on a Large Sample of Healthcare Workers During the COVID-19 Pandemic

Introduction: Working during the Sars-CoV-2 pandemic healthcare workers (HCWs) had to wear Personal Protective Equipment (PPEs) for extended periods of time, leading to an increase in dermatological reactions. The study evaluates the prevalence of adverse skin reactions to PPEs among Italian healthcare workers during the COVID-19 pandemic, and aims to determine whether prolonged PPEs usage poses a significant occupational health risk, by measuring the loss of work days and the eligibility of workers that requested health surveillance due to dermatological PPEs reactions. Materials and Methods: An online ad hoc questionnaire was administered to a sample of Italian HCWs. Questions verted on sociodemographic characteristics, PPEs usage, and occupational well-being. Descriptive analyses and logistic regressions were performed to explore possible associations between variables. Results: Two types of PPEs, Gloves and Masks, were tested. The sample included 1,223 interviewed HCWs, 1,184 gave their consent for participation. A total of 90 medical surveillance visits were requested due to PPEs related dermatological issues: in 30 cases were recognized limitations in working duties and in one case the worker was deemed not fit to keep working. Furthermore, 25 workers had a loss of occupational days due to dermatological issues. A statistically significant correlation was observed with being a nurse or midwife (OR = 1.91, IC = 1.38–2.63, p < 0.001), and being female (OR = 2.04, IC = 1.49–2.78, p < 0.001), which acted as risk factors. Discussion: The enhanced protection measures put in place during the COVID-19 pandemic, highlight the importance of occupational dermatology. This study could contribute to assess the issue, aiming to develop better prevention strategies in the workplace in order to improve well-being of HCWs and reduce the impact of dermatological adverse reactions to PPEs
