A Organização Mundial da Saúde - OMS confirmou a circulação internacional do novo Coronavírus em janeiro de 2020, nomeando-o como COVID-19 e, declarando uma pandemia. É de extrema importância que durante a pandemia, os profissionais de saúde tenham acesso e conhecimento sobre o uso correto dos Equipamentos de Proteção Individual (EPIs) e suas indicações, tomando assim, as devidas precauções na prevenção de infecções. O presente estudo buscou identificar a padronização mundial quanto ao uso dos EPIs utilizados no atendimento a pacientes suspeitos e/ou confirmados de COVID-19 no Brasil, EUA, China, Espanha, Itália e demais países europeus. Os guidelines apresentam a padronização quanto ao uso dos EPIs utilizados no atendimento a suspeitos e/ou confirmados de COVID-19, indo ao encontro das recomendações fornecidas pela OMS. Até o momento, o uso de EPIs é sem dúvida a estratégia mais importante e eficaz para proteger os profissionais de saúde durante a assistência ao paciente com COVID-19.Descritores: Infecções por Coronavírus, Equipamento de Proteção Individual, Pessoal de Saúde, Enfermagem. Recommendations for personal protective equipment to combat COVID-19Abstract: The World Health Organization - WHO confirmed the international circulation of the new Coronavirus in January 2020, naming it as COVID-19 and declaring a pandemic. It is extremely important that during the pandemic, health professionals have access and knowledge about the correct use of Personal Protective Equipment (PPE) and its indications, thus taking appropriate precautions to prevent infections. The present study sought to identify the worldwide standardization regarding the use of PPE utilized to take care of suspected and confirmed patients with COVID-19 in Brazil, USA, China, Spain, Italy and other European countries. The guidelines present a standardization regarding the use of PPE utilized to take care of suspected and confirmed with COVID-19, in line with the recommendations provided by WHO. To date, the use of PPE is undoubtedly the most important and effective strategy to protect healthcare professionals during care for patients with COVID-19.Descriptors: Coronavirus Infections, Personal Protective Equipment, Health Personnel, Nursing. Recomendaciones para el equipo de protección personal para combatir COVID-19Resumen: La Organización Mundial de la Salud - La OMS confirmó la circulación internacional del nuevo Coronavirus en enero de 2020, nombrándolo COVID-19 y declarando una pandemia.

Hydroxyapatite (HA) is a very common material used for biomedical applications. Usually, in order to improve its poor mechanical properties is combined or coated with other high-strength materials.The present paper reports the manufacturing and the biocompatibility behaviour of two different biocomposite coatings consisting of alumina (Al2O3) and hydroxyapatite (HA) using the high velocity oxygen fuel (HVOF) spraying method which were deposited onto the surface of a commercially pure titanium substrate. The biological properties of the Al2O3-HA materials were evaluated by in vitro studies. The morphology of the coatings before and after their immersing in the simulated body fluid (SBF) solution was characterized by scanning electron microscopy (SEM). The results showed an important germination of the biologic hydroxyapatite crystallite on the surface of both coatings.
