ABSTRACT: The use of nitrogen (N) in pastoral ecosystems leads to increased productivity, as it allows the plant to elongate its leaves and, therefore, grazing herbivores harvest the green leaves. However, there are very volatile N sources, which can be replaced by ammonium nitrate, which is less volatile and less dependent on the application in rainy days. The treatments are compound of Marandu palisade grass pastures managed under continuous stocking at a canopy height of 25 cm, with different levels of N fertilizer: 0, 75, and 150 kg ha-1year-1, as ammonium nitrate (32% of N), with four replicates (pastures) in a completely randomized design. Nitrogen uptake (54.9, 96.5, 113.8 kg N ha-1) and N nutrition index (0.67, 0.98, 1.15) were different between N level, respectively, 0, 75 and 150 kg ha-1 year-1. The N recovery (58.3, 40.9 %) differed between 75 and 150 kg ha-1 year-1, respectively. The dose of 75 kg N kg ha-1 year-1 results in better N utilization, while the dose of 150 kg N ha-1 year-1 enables greater stocking rate; therefore, requiring less grazing area.

RESUMO: O uso de nitrogênio (N) em ecossistemas pastoris leva ao aumento da produtividade, pois permite que a planta alongue suas folhas e, portanto, os herbívoros colham as folhas verdes. Porém, existem fontes de nitrogênio muito voláteis, que devem ser substituídas por nitrato de amônio, que é menos volátil e menos dependente da aplicação em dias chuvosos. Os tratamentos foram compostos por pastagens de capim-marandu, manejadas sob lotação contínua, na altura do dossel a 25 cm, com diferentes doses de N: 0, 75 e 150 kg ha-1 ano-1, na forma de nitrato de amônio (32% de N), com quatro repetições (piquetes), em delineamento inteiramente casualizado. A absorção de nitrogênio (54,9; 96,5; 113,8 kg N ha-1) e o índice nutricional de N (0,67; 0,98; 1,15) foram diferentes entre as doses de N, respectivamente, 0, 75 e 150 kg ha-1 ano-1. A recuperação de N (58,3; 40,9%) diferiu entre 75 e 150 kg ha-1 ano-1, respectivamente. A dose de 75 kg N kg ha-1 ano-1 resultou em melhor aproveitamento do N, enquanto a dose de 150 kg N ha-1 ano-1 possibilita maior taxa de lotação; portanto, exigindo menos área de pastagem.

ABSTRACT Aedes (Stegomyia) albopictus (Skuse, 1854) was reported in Brazil for the first time in 1986 and has shown marked expansion throughout the Brazilian territory. During a routine activity to control dengue fever conducted by the Division of Entomology of the Municipal Health Department in Rio Branco city, adults and immatures of Culicidae were collected in a peri-urban area. The identified Culicidae forms indicated that they belonged to the species Ae. albopictus. This is the first official record of the presence of Ae. albopictus in the Acre State, confirming its current presence in all Brazilian states.

ABSTRACT Objective To describe and compare the clinical characteristics and outcomes of patients admitted to intensive care units during the first and second waves of the COVID-19 pandemic. Methods In this retrospective single-center cohort study, data were retrieved from the Epimed Monitor System; all adult patients admitted to the intensive care unit between March 4, 2020, and October 1, 2021, were included in the study. We compared the clinical characteristics and outcomes of patients admitted to the intensive care unit of a quaternary private hospital in São Paulo, Brazil, during the first (May 1, 2020, to August 31, 2020) and second (March 1, 2021, to June 30, 2021) waves of the COVID-19 pandemic. Results In total, 1,427 patients with COVID-19 were admitted to the intensive care unit during the first (421 patients) and second (1,006 patients) waves. Compared with the first wave group [median (IQR)], the second wave group was younger [57 (46-70) versus 67 (52-80) years; p<0.001], had a lower SAPS 3 Score [45 (42-52) versus 49 (43-57); p<0.001], lower SOFA Score on intensive care unit admission [3 (1-6) versus 4 (2-6); p=0.018], lower Charlson Comorbidity Index [0 (0-1) versus 1 (0-2); p<0.001], and were less frequently frail (10.4% versus 18.1%; p<0.001). The second wave group used more noninvasive ventilation (81.3% versus 53.4%; p<0.001) and high-flow nasal cannula (63.2% versus 23.0%; p<0.001) during their intensive care unit stay. The intensive care unit (11.3% versus 10.5%; p=0.696) and in-hospital mortality (12.3% versus 12.1%; p=0.998) rates did not differ between both waves. Conclusion In the first and second waves, patients with severe COVID-19 exhibited similar mortality rates and need for invasive organ support, despite the second wave group being younger and less severely ill at the time of intensive care unit admission.

Abstract The objectives of this study were the biostratigraphic and paleobiogeographic interpretations of the calcareous nannofossil records of the Romualdo Formation (Aptian-Albian) in the south-central portion of the Araripe Basin. The methods used to process the samples were decanting, smear slide, centrifugation, and ultra-thin section confection. The taxonomic and biostratigraphic interpretations were carried out through qualitative and quantitative investigations. A total of 11 genera and 17 species of calcareous nannofossils, namely, Biscutum constans, Biscutum sp., Braarudosphaera africana, Braarudosphaera sp., Calculites sp., Discorhabdus ignotus, Hayesites albiensis, Hayesites sp., Nannoconus bucheri, Nannoconus sp., Retecapsa surirella, Rhagodiscus sp., Thoracosphaera sp., Watznaueria barnesiae, Watznaueria sp., Zeughrabdotus erectus, and Zeughrabdotus noeliae were identified. The integrated analysis of three outcrops suggests two distinct marine phases: the first in the Aptian, recognized in two outcrops, and during the Albian age. The genera Hayesites and Nannoconus suggest a strong Tethyan affinity. Differently, other calcareous nannofossils such as Watznaueria, Thoracosphaera, and Braarudosphaera recorded here are considered more resistant, cosmopolitan, and/or opportunistic species. Biscutum and Zeughrabdotus are sensitive calcareous nannofossils because they are more susceptible to dissolution and cannot be surely used to define this paleobiogeography and biostratigraphic range.

Abstract Tracheary elements can be classified as tracheids or vessel elements. In ferns, both cell types and even cells with intermediate characteristics can be observed. For a long time, the methods employed in the study of these cells were questioned and consequently their classification as well. In the present work, we analyze the stem tracheal elements of 13 Aspleniaceae species, occurring in different habitats and belonging to different clades. The samples were cut, dried on a hotplate, metallized, and analyzed in SEM. In general, the Asplenium species analyzed contain elongated conducting cells with oblique end walls, with scalariform thickening on all faces of the cell. The presence of pit membranes, however, varies greatly among species, it being possible to observe species with tracheids, with intermittent perforation plates, and with vessel elements.

Resumo Os elementos traqueais podem ser classificados como traqueídeos ou elementos de vaso. Nas samambaias podem ser observados ambos os tipos de células e até mesmo células com características intermediárias. Durante muito tempo os métodos empregados no estudo dessas células foram questionados e consequentemente a sua classificação também. No presente trabalho analisamos os elementos traqueais do caule de 13 espécies de Aspleniaceae, ocorrendo em diferentes habitats e pertencentes a diferentes clados. As amostras foram cortadas, secas em placa quente, metalizadas e analisadas em MEV. Em geral, as espécies de Asplenium analisadas contêm células condutoras alongadas com paredes terminais oblíquas, com espessamento escalariforme em todas as faces da célula. A presença de membranas de pontoações, entretanto, varia muito entre as espécies, sendo possível observar espécies com traqueídeos, com placas de perfuração intermitentes e com elementos de vasos.

ABSTRACT Objective: The optimal time for a neck ultrasound (US) in the follow-up of papillary thyroid cancer (PTC) after the first year is undetermined. We aimed to verify the utility of routine neck US in the surveillance of patients diagnosed with low- and intermediate-risk PTC with no evidence of disease at the one-year assessment. Materials and methods: We conducted a retrospective longitudinal study of patients with low- and intermediate-risk PTC with normal neck US, unstimulated serum thyroglobulin (Tg) < 1 ng/mL and negative anti-Tg antibodies at the one-year follow-up. Patients were divided into group 1 [undetectable Tg (<0.20 ng/mL)] and group 2 [detectable Tg but < 1 ng/mL]. The negative predictive value (NPV) of the one-year unstimulated Tg at the five-year and last follow-up visits was calculated. Results: We included n = 88 patients in group 1 and n = 8 patients in group 2. No patient from group 1 presented suspicious US findings at the five-year evaluation [NPV: 100.0% (95% confidence interval (CI): 95.5%-100.0%)], and at the last visit, only one patient had developed a lymph node classified as suspicious [NPV: 98.8% (95% CI: 93.2%-100.0%); mean follow-up: 6.7 years]. In group 2, two patients’ USs presented suspicious findings at the five-year evaluation [NPV: 75.0% (95% CI: 34.9%-96.8%)]. At the last visit, only one patient persisted with suspicious findings in the US [NPV: 87.5% (95% CI: 47.4%-99.7%); mean follow-up: 6.5 years]. Conclusion: Low- and intermediate-risk PTC with an excellent response to treatment at the one-year assessment can be safely monitored with regular unstimulated Tg assessments. Conclusions should not be drawn for Tg levels between 0.20-0.99 ng/mL.

O objetivo foi estimar o percentual de pessoas privadas de liberdade no Espírito Santo, Brasil, infectados com o SARS-CoV-2 e apresentar os fatores associados ao resultado positivo. Trata-se de um inquérito sorológico, realizado entre os dias 31 de agosto e 4 de setembro de 2020, nas 34 unidades prisionais do estado. Realizou-se uma entrevista e testes sorológicos para detecção de IgG e IgM no grupo estudado. Foram avaliadas 844 pessoas privadas de liberdade, 265 testaram positivo para COVID-19, indicando uma prevalência de 31,64% (IC9%%: 28,44-34,83). Observou-se associação estatística entre resultado positivo e localização do presídio na região norte (p = 0,001), regime de prisão fechado (p = 0.002) e sexo masculino (p = 0.005). Destaca-se ainda que todos os sintomas foram observados em menor frequência no grupo dos positivos, assim como uma baixa prevalência de comorbidades (0 a 7,1%). Os resultados permitiram conhecer as características dessa população vulnerável a fim de direcionar ações de saúde.

The study aimed to estimate the proportion of prison inmates in the state of Espírito Santo, Brazil, with SARS-CoV-2 infection and to present factors associated with positive test result. This was a serological survey conducted from August 31 to September 4, 2020, in the state’s 34 prison units. An interview and serological tests were performed for detection of IgG and IgM in the group. A total of 844 prison inmates were assessed, 265 of whom tested positive for COVID-19, indicating 31.64% prevalence (95%CI: 28.44-34.83). Statistically significant associations were seen between positive test and location of the prison in the north of the state (p = 0.001), closed imprisonment (p = 0.002), and male gender (p = 0.005). All symptoms were observed less frequently in the group that tested positive, and there was a low prevalence of comorbidities (0 to 7.1%). The results revealed the characteristics of this vulnerable population and can help target health measures.

ABSTRACT BACKGROUND: The fragility of healthcare systems worldwide had not been exposed by any pandemic until now. The lack of integrated methods for bed capacity planning compromises the effectiveness of public and private hospitals’ services. OBJECTIVES: To estimate the impact of the COVID-19 pandemic on the provision of intensive care unit and clinical beds for Brazilian states, using an integrated model. DESIGN AND SETTING: Experimental study applying healthcare informatics to data on COVID-19 cases from the official electronic platform of the Brazilian Ministry of Health. METHODS: A predictive model based on the historical records of Brazilian states was developed to estimate the need for hospital beds during the COVID-19 pandemic. RESULTS: The proposed model projected in advance that there was a lack of 22,771 hospital beds for Brazilian states, of which 38.95% were ICU beds, and 61.05% were clinical beds. CONCLUSIONS: The proposed approach provides valuable information to help hospital managers anticipate actions for improving healthcare system capacity.

Resumo Mesmo no período em que a pandemia de Covid-19 encontrava-se em crescimento no Nordeste do Brasil, iniciou-se a adoção de medidas de flexibilização do distanciamento social. O objetivo do estudo é o de avaliar a pertinência das propostas de flexibilização, tomando-se em conta a situação da pandemia em cada local e o momento em que foram adotadas. Tendo como referência as diretrizes da OMS, foram construídos e analisados indicadores operacionais para cada diretriz, no contexto da região Nordeste. Para análise do comportamento da epidemia, conforme indicadores selecionados, foram usadas técnicas de Joinpoint Trend Analysis, mapas de calor, razão de taxas e comparação da tendência temporal entre capitais e interior dos estados. O pico do crescimento semanal ocorreu em maio-julho/2020 (semanas epidemiológicas 19 a 31). Na maioria das capitais não se observou tendência decrescente simultânea do número de casos e óbitos nos 14 dias prévios à flexibilização. Em todos os estados o quantitativo de testes realizados foi insuficiente. Na semana epidemiológica 24 os percentuais estaduais de ocupação de leitos de UTI/Covid-19 foram próximos ou superiores 70%. A situação epidemiológica das nove capitais dos estados do Nordeste, no momento em que a decisão de flexibilização foi tomada, mostra que nenhuma delas atendia aos critérios e parâmetros recomendados pela OMS.

Abstract Even in the period when the Covid-19 pandemic was on the rise in the Northeast of Brazil, the relaxation of social distancing measures was introduced. The scope of the study is to assess, in the light of the epidemiological-sanitary situation in the region, the suitability of relaxation of social distancing measures. Based on the WHO guidelines for relaxation of social distancing, operational indicators were created and analyzed for each guideline in the context of the Northeast. To analyze the behavior of the epidemic, according to selected indicators, Joinpoint trend analysis techniques, heat maps, rate ratios and time trends between capitals and the state interior were compared. The weekly growth peak of the epidemic occurred in May-July 2020 (epidemiological weeks 19 to 31). In most capitals, there was no simultaneous downward trend in the number of cases and deaths in the 14 days prior to flexibilization. In all states the number of tests performed was insufficient. In epidemiological week 24, the state percentages of ICU/Covid-19 bed occupancy were close to or above 70%. The epidemiological situation of the nine Northeastern state capitals analyzed here did not meet criteria and parameters recommended by the World Health Organization for the relaxation of social distancing measures.

Preeclampsia is a multifactorial disease. Among these factors, untreated hypertension during pregnancy can result in high morbidity and mortality rates and may also be related to the future development of cardiovascular diseases.Therefore, this systematic review aimed to determine the association of previous preeclampsia with the future development of cardiovascular diseases. Studies on the association between preeclampsia and future cardiovascular diseases published in the last 10 years (2009-2019) were identified from the PubMed/Medline (207 articles), Embase (nine articles), and Cochrane (three articles) databases using the keywords “preeclampsia” and “future cardiovascular diseases”, “preeclampsia” and “future heart attack”, and “preeclampsia” and “future cardiac disease”. After applying the inclusion and exclusion criteria, 15 articles were analyzed by systematic review and meta-analysis according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. The meta-analysis and the determination of the quality of the articles were conducted using RevMan software, version 5.3. Statistically significant differences were observed between the control and previous preeclampsia groups with respect to systolic blood pressure (mean difference [MD] 4.32; 95% confidence interval [95%CI] 3.65, 4.99; p<0.001), diastolic blood pressure (MD): 2.11; 95%CI: 1.68, 2.55; p<0.0001), and insulin level (MD: 2.80; 95% CI: 0.50, 5.11; p<0.001). Body mass index (MD: 2.57, 95%CI: 2.06, 3.07; p=0.0001), total cholesterol (MD: 10.39; 95%CI: 8.91, 11.87; p=0.0001), HDL (MD: 2.83; 95%CI: 2.20, 3.46; p=0.0001), and LDL (MD: 1.77; 95%CI: 0.42, 3.13; p=0.0001) also differed significantly between groups. Thus, the results of the present study showed that women with a history of preeclampsia were more likely to develop cardiovascular disease.
