    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

    Com o objetivo de avaliar a variabilidade espacial de propriedades do solo e produção de cafĂ© em diferentes SuperfĂ­cies GeomĂłrficas (SG) na regiĂŁo do Alto ParanaĂ­ba, MG, instalaram-se duas malhas de 200 x 850 m com intervalos regulares de 50 m, com 68 pontos amostrais cada uma, sob cultivo de cafĂ©. As amostras de solo foram coletadas na profundidade de 0-0,20 m, nos pontos de intercessĂŁo dessas malhas. A produção de cafĂ© foi avaliada em duas colheitas de grĂŁos em coco das plantas mais prĂłximas da intercessĂŁo de linhas das malhas. Calcularam-se as estatĂ­sticas descritivas e realizou-se a anĂĄlise geoestatĂ­stica de propriedades do solo e produção da cultura de cafĂ©. As propriedades quĂ­micas e granulomĂ©tricas de solos intensamente manejados, possuem dependĂȘncia do relevo, mesmo de pequena expressĂŁo. A produção de cafĂ© apresentou dependĂȘncia espacial em ambas as superfĂ­cies e maior variabilidade na SG II. Os limites entre as superfĂ­cies geomĂłrficas podem representar limites de locais especĂ­ficos de manejo.<br>With the objective to evaluate the spatial variability of the soil properties and coffee production in different geomorphic surfaces (GS) in the region of the high ParanaĂ­ba, MG, two regular grids of 200 x 850 m with intervals of 50 m were installed with 68 sampling points under coffee crop. The soil samples were collected at 0-0.20 m depth at the intersection points of these grids. The coffee production was evaluated in plants closer to the intersection of the grid point. Descriptive statistics and geostatistics analysis of the soil properties and production of coffee crop were performed. The chemical and textural properties of soil intensely managed possess dependence of the relief, even for small expression. The coffee production presented spatial dependence in both surfaces and largest variability in GS II. The limits between the geomorphic surfaces can represent limits of specific places of management
