    Improving the Sunscreen Properties of TiO2 through an Understanding of Its Catalytic Properties

    The use of particulate titanium dioxide (TiO2) as an active sunscreen ingredient has raised concerns about potential risks from TiO2-mediated free radical formation. To date, remediation attempts have concentrated on reducing the yield of free radical generation by TiO2 upon sunlight exposure. The problem with this approach is that given the band gap in TiO2, production of radical and the ensuing reactive oxygen species (ROS) is completely normal. Our strategy is based on a nontoxic, biocompatible shell that neutralizes the free radicals by scavenging them with natural antioxidants before they exit the particle. The new lignin@TiO2 composites preserve the scattering and absorption properties of TiO2 because the particles retain their nanoscale dimensions as preferred by the cosmetic industry. Although the target properties for photocatalysis and sun-protection applications are opposite, we argue that exactly the same knowledge is required to optimize either one

    Italy: Health system review

    No full text
    The Health Systems in Transition (HiT) series consists of country-based reviews that provide a detailed description of a health system and of reform and policy initiatives in progress or under development in a specific country. Each review is produced by country experts in collaboration with the Observatory’s staff. In order to facilitate comparisons between countries, reviews are based on a template prepared by the European Observatory, which is revised periodically. The template provides detailed guidelines and specific questions, definitions and examples needed to compile a report

    Italy: Health System Review

    This analysis of the Italian health system reviews recent developments in organization and governance, health financing, health care provision, health reforms and health system performance. Italy has a regionalized National Health Service (SSN) that provides universal coverage largely free of charge at the point of delivery, though certain services and goods require a co-payment. Life expectancy in Italy is historically among the highest in the EU. However, regional differences in health indicators are marked, as well as in per capita spending, distribution of health professionals and in the quality of health services. Overall, Italy's health spending per capita is lower than the EU average and is among the lowest in western European countries. Private spending has increased in recent years, although this trend was halted in 2020 during the coronavirus disease 2019 (COVID-19) pandemic. A key focus of health policies in recent decades was to promote a shift away from unnecessary inpatient care, with a considerable reduction of acute hospital beds and stagnating overall growth in health personnel. However, this was not counterbalanced by a sufficient strengthening of community services in order to cope with the ageing population's needs and related chronic conditions burden. This had important repercussions during the COVID-19 emergency, as the health system felt the impact of previous reductions in hospital beds and capacity and underinvestment in community-based care. Reorganizing hospital and community care will require a strong alignment between central and regional authorities. The COVID-19 crisis also highlighted several issues pre-dating the pandemic that need to be addressed to improve the sustainability and resilience of the SSN. The main outstanding challenges for the health system are linked to addressing historic underinvestment in the health workforce, modernizing outdated infrastructure and equipment, and enhancing information infrastructure. Italy's National Recovery and Resilience Plan, underwritten by the Next Generation EU budget to assist with economic recovery from the COVID-19 pandemic, contains specific health sector priorities, such as strengthening the country's primary and community care, boosting capital investment and funding the digitalization of the health care system
