Resumo Este artigo apresenta os impactos da pandemia nos sistemas de saúde e as repercussões nas condições de trabalho e saúde mental dos profissionais de saúde e trabalhadores invisíveis da saúde no contexto da COVID-19. Apresenta a mortalidade entre os profissionais da saúde destacando a necessidade de melhores condições de trabalho e de segurança para os trabalhadores da saúde e melhora da gestão pública. Enfatiza as recomendações da OMS/OPAS, a necessidade de vacinação equânime, incluindo os países mais pobres e as populações mais vulneráveis. Relata os impactos da interrupção dos serviços essenciais em saúde, como para as doenças crônicas e infecciosas, e os prejuízos causados pela disseminação de informações falsas pela rede social, e lembra da necessidade de veiculação de informações corretas e seguras na saúde.

Abstract This article discusses the impacts of the COVID-19 pandemic on health systems and its effects on the working conditions and mental health of health professionals and invisible health workers. It presents data on deaths among health professionals, highlighting the need for better and safer working conditions and improvements in public management. We emphasize WHO/PAHO recommendations and the need for equitable vaccine distribution, including poor countries and vulnerable populations. We also highlight the impacts of interrupting essential health services, such as the treatment of chronic conditions and infectious disease prevention, and the damage caused by the dissemination of fake news, stressing the need to improve access to correct and safe health information.

ABSTRACT Background: In order to standardize a thrombin generation() protocol, we analyzed the analytical variables and sensitivity of this test to hypo/hypercoagulability states. Methods: The effect of the tissue factor concentration and the intra- and interassay precision were analyzed. To evaluate the hypercoagulability status, the plasma of women under an oral contraceptive was tested, while plasma from hemophilia A patients at 1, 3 and 7 days after recombinant FVIII infusion, and lyophilized plasma deficient in FVII or FVIII were used for the evaluation of hypocoagulability. Results: The intra-assay coefficient of variation was <10% with 1 and 5 pM of low and high TF. The oral contraceptive users showed increased thrombin generation in comparison to non-users, which was more pronounced with low TF (endogenous thrombin potential ETP) p = 0.0009; peak p = 0.0009; lagtime p = 0.0008). In relation to the FVIII-deficient plasma, a higher TG was observed as FVIII levels were increased and a better discrimination was obtained for different concentrations of FVIII with low TF (ETP p < 0.0001; peak p < 0.0001; lagtime p = 0.0004). Using low TF, plasma from hemophilia A patients showed higher TG values after 1 day of recombinant FVIII infusion vs after 3 days (ETP p < 0.0001; peak p < 0.0001; lagtime p = 0.0407), while the lowest values were observed after 7 days. With FVII-deficient plasma, thrombin generation was lower than normal plasma and a more pronounced difference was observed with high TF compared to low TF (ETP p < 0.0001; peak p < 0.0001; lagtime p < 0.0001). Conclusion: Under our conditions the thrombin generation test seems to be sensitive to evaluation of hyper/hypocoagulability states. Standardization of the thrombin generation test may have an application in the evaluation of bleeding and thrombotic disorders.
