Este estudo tem como objetivo apresentar a caracterização da cobertura vegetal e da fauna da área de um empreendimento localizado em Itacoatiara (Estado do Amazonas), sendo parte integrante de um Estudo Ambiental Simplificado. O método escolhido para a coleta de dados primários foi o 'Caminhamento' para obtenção de informações acerca do enquadramento fitogeográfico, da fisionomia, da flora e a caracterização do uso do solo, bem como registrar animais vivos e/ou encontrar seus vestígios. Verificou-se que a área estudada foi intensamente degradada resultado do desmatamento, queimadas e do manejo inadequado da pastagem extensiva há muitos anos. Outrora, o impacto gerado foi negativo com a supressão da vegetação, imediato e direto, irreversível e de forte magnitude, uma vez que a vegetação suprimida perdeu suas características e fisionomias. Essa destruição dos ambientes afetou intensa e diretamente a população dos grupos de animais de interesse deste estudo (aves, répteis, anfíbios e mamíferos). Como as atividades da empresa serão pontuais, com abrangência limitada, em áreas já desmatadas, não haverá impactos negativos significativos sobre a flora e fauna local.

Objectives: Since the beginning of the COVID-19 pandemic, the Spanish Society of Neurology has run a registry of patients with neurological involvement for the purpose of informing clinical neurologists. Encephatopathy and encephalitis were among the most frequently reported complications. In this study, we analyse the characteristics of these complications. Patients and methods: We conducted a retrospective, descriptive, observational, multicentre study of patients with symptoms compatible with encephalitis or encephalopathy, entered in the Spanish Society of Neurology's COVID-19 Registry from 17 March to 6 June 2020. Results: A total of 232 patients with neurological symptoms were registered, including 51 cases of encephalopathy or encephalitis (21.9%). None of these patients were healthcare professionals. The most frequent syndromes were mild or moderate confusion (33%) and severe encephalopathy or coma (9.8%). The mean time between onset of infection and onset of neurological symptoms was 8.02 days. Lumbar puncture was performed in 60.8% of patients, with positive PCR results for SARS-CoV-2 in only one case. Brain MRI studies were performed in 47% of patients, with alterations detected in 7.8% of these. EEG studies were performed in 41.3% of cases, detecting alterations in 61.9%. Conclusions: Encephalopathy and encephalitis are among the complications most frequently reported in the registry. More than one-third of patients presented mild or moderate confusional syndrome. The mean time from onset of infection to onset of neurological symptoms was 8 days (up to 24 hours earlier in women than in men). EEG was the most sensitive test in these patients, with very few cases presenting alterations in neuroimaging studies. All patients treated with boluses of corticosteroids or immunoglobulins progressed favourably. (C) 2021 Sociedad Espanola de Neurologia. Published by Elsevier Espana, S.L.U.
