BACKGROUND Cryptococcosis is the most common mycosis of the central nervous system. It may develop in immunocompetent and immunocompromised patients, the latter representing most cases. The most common presentation of the disease is meningitis, whereas intra-axial lesions in the form of cryptococcoma are less frequent with a greater tendency to present in immunocompetent patients. The presentation of pituitary cryptococcoma is exceptional. To the best of the authors’ knowledge, there is only one case published in the medical literature. OBSERVATIONS The authors present the case of a 30-year-old male without a relevant medical history. He was referred to our center with a pituitary mass on magnetic resonance imaging and panhypopituitarism. The patient underwent endonasal endoscopic transsphenoidal tumor resection, and a histopathological diagnosis of pituitary cryptococcoma was made. Medical management included fluconazole and intravenous amphotericin. LESSONS This case underscores the neurosurgical and medical management of an exceptional clinical presentation of pituitary cryptococcoma in an immunocompetent patient. To the best of the authors’ knowledge, there is only one case published in the medical literature. This case provides an invaluable review of the clinical, imaging, and therapeutic considerations regarding this exceptional clinical entity.

Se concluye que la gestión de tutoría influye positivamente para el liderazgo personal y propósito de vida en tiempos de COVID 19 de estudiantes de educación universitaria.

4 pages, 5 figues, 1 table.-- XV Reunión Nacional de Cuaternario, Bizkaia Aretoa-Bilbao, 1-5 julio 2019, The capacity of fluvial potholes to trap sediments led to the hypothesis that these deposits could serve as historical records. A sediment core, obtained from an erosion pothole, was studied. 11 samples (22 cm depth) were obtained. The 210Pb dating indicated that, in general, the pothole was gradually filled in the last 33-35 years. Using trace metals as indicators (Cu, Pb and V) it was possible to estimate their natural background (61±27mgCu·kg-1, 72±45 mgPb·kg-1 and 19±4 mgV·kg-1). After calculating the normalized enrichment factor (NEF), the core showed indexes indicative of possible-moderate contamination for Cu and Pb (average contents 141±45 mgCu·kg-1 and 141±46 mgPb·kg-1), particularly in a layer (1993-2009) that seems to be a mixture of sediments of different ages, coinciding in time with human interventions in the local environment. Sediments trapped in potholes (as traps) showed potential to be used as historical records

Since the 1980s, research into entomopathogenic nematodes (EPNs) in Latin America has produced many remarkable discoveries. In fact, 16 out of the 117 recognized species of EPNs have been recovered and described in the subcontinent, with many more endemic species and/or strains remaining to be discovered and identified. In addition, from an applied perspective, numerous technological innovations have been accomplished in relation to their implementation in biocontrol. EPNs have been evaluated against over 170 species of agricultural and urban insects, mites, and plant-parasitic nematodes under laboratory and field conditions. While much success has been recorded, many accomplishments remain obscure, due to their publication in non-English journals, thesis dissertations, conference proceedings, and other non-readily available sources. The present review provides a brief history of EPNs in Latin America, including current findings and future perspectives.

2 pages.-- XV International Estuarine Biogeochemistry Symposium, Vigo, June 04-05 2019, Trace metals have a great ecological and environmental significance due to their toxicity and accumulative behavior. Most of them have increased their concentration due to human activities, impacting in their biogeochemical cycles and generating a high pressure, particularly in coastal environments. San Simon Bay is a shallow embayment located in the innermost zone of the Ría of Vigo (NW Spain). The bay supports mariculture activities of great economic importance hence, the presence of potentially toxic elements like Cd requires some vigilance. Their mobility, biological availability and potential toxicity is dependent on their chemical forms and partitioning within sediments. A gravity core (230 cm depth) was retrieved in San Simon Bay and cut into 10-cm (n = 23). Sequential extraction was performed according to the method of Campanella, et al. (1995), 5 fractions were obtained: (F1) Cd present in ion-exchange form and bound to carbonates, (F2) Cd in the reductive phase bound to manganese-iron oxides, (F3) Cd weakly bound to organic matter, (F4) Cd strongly bound to organic matter, (F5) Cd bound to sulfides. The results showed that Cd concentrations ranged from 0.1 to 2.1 mg kg-1. Cadmium exhibited considerable presence in the F1 (i.e. exchangeable and bound to carbonates) and F4 (i.e. strongly bound to organic matter) fractions. More than 75% of the total Cd was found in F1 fraction above 100 cm depth, involving a potential risk of contamination in the San Simon Bay. Moreover, Cd showed a high susceptibility to complexation with organic matter compounds, especially below 100 cm where F4 fraction reached more than 55% Cd total at some depths. In conclusion, Cd showed higher mobility and bioavailability in the surface layers remaining bound to organic matter in depth, This research was co-funded by the Spanish Ministry of Economy and Competitiveness, and the European Regional Development Fund (CGL2012-33584), and by Xunta de Galicia Project (GRC2015/020)

Este artigo tem como objetivo mensurar o impacto do aumento da demanda final da indústria de base florestal. Como instrumento de análise utiliza-se a matriz de contabilidade social do Estado do Paraná de 1998. Foi necessário calcular o multiplicares da matriz. Os efeitos de uma injeção nas variáveis exógenas sobre os segmentos de Madeira e Mobiliário e de Papel e Papelão resultaram em choques de demanda mais intensos dentro do próprio setor. Observa-se que o ramo de Madeira e Mobiliário tem maiores ligações com as atividades relativas ao setor terciário; já o segmento de Papel e Papelão, com atividades que necessitam embalagem. Conclui-se que, apesar da agregação das atividades econômicas da matriz de contabilidade social paranaense, foi possível identificar os principais impactos decorrentes do aumento da demanda final.The present article aims at measuring the final demand impact on the forest-based industry by using the 1998 State of Paraná social accounting matrix as the analysis tool. We also had to calculate the matrix multipliers. The increased effects of exogenous activity on the Wood/Furniture and Paper/Pulp activities brought a more intense demand shock to that sector. We noticed that the Wood and Furniture activity is mostly connected with the tertiary sector activities, while the Paper and Pulp activity is mostly connected with activities that need packing. Finally, we could identify the main impacts originated by an increased final demand in spite of the reduction in the number of Paraná Social Accounting Matrix economic activities.
