RESUMO: Este trabalho teve como objetivo avaliar o efeito da calagem (com e sem) e do biocarvão (com e sem) sobre o crescimento e a produção de forragem do sorgo forrageiro cv. BRS Ponta Negra e nas propriedades químicas do Neossolo Quartzarênico no ambiente Semiárido. O delineamento experimental foi em blocos casualizados, com tratamentos em esquema fatorial 2x2, correspondendo a aplicação ou não do calcário (0 e 2,5 t ha-1) e do biocarvão (0 e 12,5 t ha-1). O biochar era produzido a partir de galhos de caju. O experimento foi conduzido em parcelas de 16 m² onde foi cultivada a cultivar de sorgo forrageiro BRS Ponta Negra. Foram avaliadas as características químicas do solo, os atributos de produção e as características estruturais da cultivar de sorgo estudada. Não houve interação entre os fatores. O uso do biochar aumentou o pH e os teores de Ca e P no solo e contribuiu para o aumento da massa da panícula (2,51 t ha-1 de MS). A aplicação de calcário afetou o teor de Ca no solo, assim a dose de 2,5 t ha-1 resultou em maiores valores de diâmetro do colmo (15,25 mm), massa da panícula e massa do colmo (2,63 e 7,50 t ha-1 de MS, respectivamente). Portanto, esses resultados permitem traçar estrategias de uso do calcário e biochar para produção forrageira em ambientes semiáridos com solos arenosos. Pois, esses materias melhoram alguns atributos quimicos do solo e a produção do sorgo forrageiro. Vale ressaltar que as condições edofoclimáticas podem alterar os padrões de resposta observados nesta pesquisa. Portanto, a pesquisa em outras regiões é essencial.

ABSTRACT: This research evaluated the effect of liming (with and without) and biochar (with and without) on sorghum cv. BRS Ponta Negra growth and Arenosol chemical properties in the Semiarid environment. The experimental design was in randomized blocks, with treatments in a 2x2 factorial scheme, corresponding to the application or not of lime (0 and 2.5 t ha-1) and biochar (0 and 12.5 t ha-1). Biochar was produced from cashew branches. The experiment was conducted in 16 m² plots where the forage sorghum cultivar BRS Ponta Negra was cultivated. The soil chemical characteristics, the production attributes, and the structural characteristics of the sorghum cultivar studied were evaluated. There was no interaction between factors. The use of biochar increased the pH and Ca and P contents in the soil and contributed to increasing the panicle mass (2.51 t ha-1 of DM). Lime application affected the soil Ca content as the dose of 2.5 t ha-1 resulted in higher values of culm diameter (15.25 mm), panicle mass, and culm mass (2.63 and 7.50 t ha-1 of DM, respectively). Therefore, these results allowed to outline strategies for the use of limestone and biochar for forage production in semiarid environments in sandy soils. Because, these materials improve some chemical attributes of the soil and the production of forage sorghum. It is noteworthy that edophoclimatic conditions can change the response patterns observed in this research. Therefore, research in other regions is essential.

Resumo Objetivos: determinar a frequência de sintomas de estresse, ansiedade e depressão em pacientes sintomáticos para COVID-19 e avaliar os fatores associados. Métodos: entre maio / junho de 2020, foi realizado um estudo transversal prospectivo com participantes sintomáticos para COVID-19 (n = 300). Foi aplicado um questionário online e o DASS-21 para avaliar a saúde mental dos participantes. Resultados: observou-se que 28,6%, 29,7% e 27% dos participantes apresentaram sintomas graves/extremos para estresse, ansiedade e depressão, respectivamente. A realização do teste para a COVID-19 constituiu-se como fator de proteção para o desenvolvimento de sintomatologia psíquica, uma vez que mostrou associação significativa nas baixas frequências de depressão grave/extrema [odds ratio (OR)]= 0,26; p=0,002) e de estresse (OR=0,39; p=0,01). Conclusão: os indivíduos sintomáticos para COVID-19 constituem um grupo vulnerável que podem apresentar elevada sintomatologia para depressão, ansiedade e estresse. A identificação da frequência de morbidade psiquiátrica e seus fatores associados podem contribuir para o desenvolvimento de estratégias de saúde mental visando a prevenção e mitigação do impacto psicológico na população sintomática de COVID-19 durante a pandemia.

Abstract Objectives: to determine the frequency of stress, anxiety, and depression symptoms in symptomatic patients for COVID-19. To evaluate the associated factors involved in these variants. Methods: between May/June of 2020, it was conducted a prospective cross-section study with symptomatic participants for COVID-19 (n=300). It was applied an online questionnaire and the DASS-21 to evaluate the mental health of participants. Results: it was observed that 28.6%, 29.7% and 27% of the participants showed severe/extreme levels symptoms of stress, anxiety, and depression, respectively. The testing for COVID-19 application had constituted a protective factor for the development of psychiatric morbidity, once it had shown significant association in the low frequencies of severe/extreme depression [Odds Ratio (OR)]= 0.26; p=0.002) and stress (OR=0.39; p=0.01). Conclusion: individuals that are symptomatic for COVID-19 are a vulnerable group that may present high symptomatology for depression, anxiety, and stress. The identification of psychiatric morbidity frequency and its associated factors may contribute for the development of mental health strategies aiming at the prevention and mitigation of psychological impact in COVID-19 symptomatic population during the pandemic.

ABSTRACT OBJECTIVE To estimate the prevalence of clinical signs and symptoms of severe/extreme stress, anxiety, and depression, as well as their associated factors, among Brazilians during social distancing. METHODS This is a cross-sectional study conducted in April/May 2020 with 3,200 Brazilians over 18 years old. Respondents’ sociodemographic and clinical data were collected using an online questionnaire, which also included the 21-item Depression, Anxiety and Stress Scale (DASS-21) to assess emotional symptoms. Unadjusted and adjusted prevalence ratios and their respective 95% confidence intervals were estimated using Poisson regression models with robust variance. RESULTS Our results show the prevalence of severe/extreme stress was 21.5%, anxiety 19.4%, and depression 21.5%. In the final model, sociodemographic, clinical, and Covid-19-related factors were associated with severe/extreme stress, anxiety, and depression in Brazilians during social distancing due to the Covid-19 pandemic. We found the main factors associated with severe/extreme depression to be young women, brown, single, not religious, sedentary, presenting reduced leisure activities, history of anxiety and depression, increased medication use, and Covid-19 symptoms. CONCLUSION This study may help develop and systematically plan measures aimed to prevent, early identify, and properly manage clinical signs and symptoms of stress, anxiety, and depression during the Covid-19 pandemic.

O objetivo da investigação foi analisar vazões extremas ocorridas entre 9 e 14 de abril de 2011 na bacia do Rio Araguari-AP. A metodologia consistiu de três etapas principais: 1) re-análise da precipitação estimada pelo Modelo BRAMS (Brazilian in Development Regional Atmospheric Model System),utilizando como suporte a sinótica do mesmo período; 2) análise de vazão nas seções de monitoramento hidrológico em Porto Platon, Capivara e Serra do Navio (ADCP-Accustic Doppler Profiller Current); 3) análise estatística da série histórica de vazões máximas em Porto Platon utilizando distribuição de Gumbel. Observou-se que o modelo BRAMS capturou parcialmente o padrão do sistema de precipitação quando comparado com a análise sinótica e com os dados da literatura, mas demandando ainda otimização na representação de respostas hidrológicas extremas. Em Porto Platon foi registrada uma vazão recorde de 4036 m3/s, cujo comportamento foi analisado sob a ótica dos mecanismos disponíveis de monitoramento no Estado. Concluiu-se que tais eventos extremos são pouco detectáveis e oferecem riscos consideráveis aos usuários da bacia. A previsão de vazão, baseada na série hidrológica disponível, era de 100 anos de retorno, mas as análises revelaram que este período seria de 360 anos, indicando significativa fragilidade do sistema de previsão de eventos extremos no Estado.

The objective of this investigation was to analyse the extreme river flows which have occurred between 9 and 14 April 2011 in the Rio Araguari-AP. The methodology consisted of three main steps: 1) re-analysis of precipitation estimated by the BRAMS (Brazilian Development in Regional Atmospheric Model System) model using the synoptic of the same period as support, 2) analysis of streamflow in sections of hydrological monitoring in Porto Platon, Capivari and Serra do Navio (ADCP-Accustic Profiller Doppler Current); 3) statistic analysis of the time series of maximum river flows in Porto Platon using Gumbel distribution. It was observed that the BRAMS system partially captured the standard precipitation when compared with the synoptic analysis and literature data, but the extreme hydrological responses representation still needs an optimization. In Porto Platon a flow record of 4036 m3 /s was recorded, whose behavior was analyzed from the perspective of the available monitoring mechanisms in the State. It was concluded that such extreme events are poorly detectable and offer considerable risks to users of the basin. The stream flow prediction based on available hydrological series was 100 years recurrence, but the analysis have revealed that this period would be 360 years, indicating significant deficiency of the prediction system of extreme events in the State.

OBJETIVOS: descrever o perfil epidemiológico e clínico das pacientes admitidas com o diagnóstico de sepse puerperal de origem pélvica em uma Unidade de terapia intensiva (UTI) obstétrica. MÉTODOS: um estudo de corte transversal, de fevereiro a agosto de 2010, foi conduzido. Foram investigados os casos de sepse puerperal de origem pélvica admitidas na UTI obstétrica do Instituto de Medicina Integral Prof. Fernando Figueira (IMIP) - Recife - Brasil. As variáveis analisadas foram: idade, procedência, realização de pré-natal, via de parto, uso de sonda vesical, uso de cateter venoso central, intubação, uso de droga vasoativa, realização de relaparotomia, o número de relaparotomias realizadas, realização de histerectomia, ocorrência de complicações e óbito. RESULTADOS: identificamos 77 admissões por sepse, sendo 35 puerperal de origem genital. A idade média foi de 22,6 anos, a maioria procedente de cidades do interior do estado. 52,9% das mulheres tinham até 20 anos. 62,5% eram primíparas e 68,6% haviam sido submetidas a cesárea. Em relação à temperatura, 42,8% das pacientes apresentaram valores abaixo de 35ºC ou acima de 37,8ºC. Complicações ocorreram em 45,7% das pacientes. Diálise foi indicada em 40% e droga vasoativa utilizada em 22,9%. Histerectomia foi realizada em 44,1% das pacientes, sendo necessário relaparotomia em 54,3%. CONCLUSÕES: a sepse puerperal de origem genital é doença grave, que acomete mulheres jovens de baixa paridade. A freqüência de complicações e de procedimentos invasivos nesse grupo de mulheres é alto o que implica em alta morbidade e mortalidade. Conhecer de forma mais detalhada esse grupo de pacientes contribui com o conhecimento atual sobre a doença, melhorando a preparação dos centros para lidar a sepse puerperal de origem genital.

OBJECTIVES: to describe the clinical and epidemiological profile of patients admitted with the diagnosis of puerperal sepsis of pelvic origin in an intensive care unit (ICU). METHODS: a cross-sectional study, from February to August 2010 was conducted. Cases of puerperal sepsis from pelvic origin admitted to the ICU obstetric Institute of Integrative Medicine Professor Fernando Figueira (IMIP) - city of Recife - Brazil were investigated. The variables were: age, origin, conducting pre-natal, delivery route, use of urinary catheter, central venous catheter, intubation, vasoactive drugs, conducting relaparotomy, the number of performed relaparotomies, performing hysterectomies, the incidence of complications and death. RESULTS: 77 identified admissions for sepsis, and 35 postpartum. The mean age was 22.6 years, most coming from towns of the state. 52.9% of women were aged 20 years. 62.5% were primiparous and 68.6% had undergone cesarean section. Concerning temperature, 42.8% of patients had values below 35ºC or above 37.8ºC. Complications occurred in 45.7% of patients. Dialysis was indicated in 40% and vasoactive drug used in 22.9%. Hysterectomy was performed in 44.1% of patients, in 54.3% relaparotomy necessary. CONCLUSIONS: genital puerperal sepsis is a serious disease that affects young women with low parity. The frequency of complications and invasive procedures in this group of women is high, which implies a high morbidity and mortality. Describing this group of patients contributes with current knowledge about the disease, improving the preparation of the Centers for dealing with genital puerperal sepsis.
