ABSTRACT The objective of this study was to evaluate the effect of combinations of nitrogen, phosphorous and potassium doses on the production components of custard-apple irrigated with saline waters. The experiment was conducted in a greenhouse, using a Neossolo Regolítico (Entisol) of clay loam texture in Campina Grande-PB, Brazil. The treatments were distributed in a randomized block design, in a 2 × 8 factorial scheme, with three replicates, corresponding to two levels of electrical conductivity of water - ECw (0.8 and 3.0 dS m-1) and eight combinations of fertilization with nitrogen, phosphorus and potassium (100-100-100; 100-100-125; 100-125-100; 100-125-125; 125-100-100; 125-100-125; 125-125-100 and 125-125-125% of the recommendation, for the third year of cultivation). The combination of 100-100-100% corresponded to 100, 60 and 60 g of N, P2O5, K2O per plant per year, respectively. High concentrations of salts in the irrigation water reduced the number of fruits, fresh fruit mass, total number of seeds and mass of seeds of custard-apple. Plants achieved the best development when grown under 125-100-100, 125-125-125 and 100-100-100% combinations of N-P-K recommendation. Irrigation with ECw of 3.0 dS m-1 associated with the 100-125-125% combination of fertilization increased the average mass and height of the custard-apple fruits.
RESUMO Objetivou-se com este estudo avaliar o efeito das combinações de doses de nitrogênio, fosforo e potássio nos componentes de produção da pinheira irrigadas com águas salinas. O experimento foi desenvolvido em casa de vegetação, utilizando-se de um Neossolo Regolítico (Entisol) de textura franco- argilosa em Campina Grande-PB. Os tratamentos foram distribuídos em delineamento experimental em blocos ao acaso, em esquema fatorial 2 × 8, com três repetições, sendo dois níveis de condutividade elétrica da água - CEa (0,8 e 3,0 dS m-1) e oito combinações de adubação com nitrogênio, fósforo e potássio (100-100-100; 100- 100-125; 100-125-100; 100-125-125; 125-100-100; 125-100-125; 125-125-100 e 125-125-125% da recomendação, referente ao terceiro ano de cultivo). A combinação de 100-100-100% correspondeu a 100, 60 e 60 g de N, P2O5, K2O por planta anual, respectivamente. As altas concentrações de sais na água de irrigação diminuiu o número de frutos, a massa fresca de frutos, número total e a massa de sementes da pinheira. As plantas de pinha alcançaram o melhor desenvolvimento quando cultivadas nas combinações 125-100-100; 125- 125-125 e 100-100-100% de N-P-K recomendação. A irrigação com CEa de 3,0 dS m-1 associada com a combinação de adubação 100-125-125% aumentou a massa média e altura dos frutos de pinheira.

ABSTRACT ‘BRS F183’ (Potira) is a late-maturing and red skin potato cultivar, suitable for French fry processing, due to tuber high dry matter content of long oval shape, large size, light yellow flesh, and light fry color. It is also suitable for the fresh market due to its attractive tubers of intense red color, smooth skin and shallow eyes. In six trials, ‘BRS F183’ showed average tuber yields that did not differ from ‘Asterix’. The marketable yield was relatively high, reaching 98.5% in the tropical ecosystem. Larger tubers of ‘BRS F183’ than ‘Asterix’ were also observed in the autumn crop of the subtropical ecosystem. In most of the trials, the dry matter content was higher than that of ‘Asterix’, varying from 20.5 to 23.0%. A very low incidence of tuber disorders was observed in ‘BRS F183’, with the secondary growth lower than ‘Asterix’. ‘BRS F183’ presented medium tuber dormancy. Tuber glucose content suitable for French fry processing (≤1.2 mg g-1 of fresh mass) was shown by ‘BRS F183’ after harvest and storage at 7.5°C, 8.9°C and 20°C for up to 180 days, while ‘Asterix’ was suitable up to 120 days after storage at 8.9ºC. ‘BRS F183’ is moderately resistant to early blight and moderately susceptible to late blight. It is susceptible to PVY, PLRV, and root-knot nematode. Field observations indicate that resistance/susceptibility to soft rot, black scurf, and bacterial wilt of ‘BRS F183’ is not different from the main cultivars grown in the country. However, higher susceptibility to common scab was shown in some validation tests. ‘BRS F183’ was released in 2020 by Embrapa, as a product of the breeding program developed by Embrapa Temperate Agriculture and Embrapa Vegetables.
RESUMO ‘BRS F183’ (Potira) é uma cultivar de batata de maturidade tardia e película vermelha, adequada ao processamento de palitos pré-fritos, devido ao alto teor de matéria seca dos tubérculos de formato ovalado longo, tamanho grande, polpa amarela clara e coloração clara de fritura. Também é indicada para o mercado fresco devido a seus tubérculos atrativos de cor vermelha intensa, película lisa e olhos rasos. Em seis ensaios, ‘BRS F183’ apresentou rendimentos de tubérculos que não diferiram de ‘Asterix’. O rendimento comercial foi relativamente alto, chegando a 98,5% no ecossistema tropical. Tubérculos maiores da ‘BRS F183’ que ‘Asterix’ foram também observados na safra de outono do ecossistema subtropical. Na maioria dos ensaios, o teor de matéria seca foi superior ao da ‘Asterix’, variando de 20,5 a 23,0%. Baixa incidência de desordens dos tuberculos foi observada na ‘BRS F183’, com o crescimento secundário menor que ‘Asterix’. ‘BRS F183’ apresentou dormência média dos tubérculos. Teor de glicose dos tubérculos adequado para processamento de palitos pré-fritos (≤1,2 mg g-1 de massa fresca) foi apresentado pela ‘BRS F183’, após a colheita e armazenamento a 7,5°C, 8,9°C e 20°C por até 180 dias, enquanto de ‘Asterix’ foi adequado até 120 dias após armazenamento a 8,9°C. ‘BRS F183’ é moderadamente resistente à pinta preta e moderadamente suscetível à requeima. É suscetível a PVY, PLRV e nematóide das galhas. Observações de campo indicam que a resistência/suscetibilidade à podridão mole, crosta preta e murcha bacteriana da ‘BRS F183’ não é diferente das principais cultivares cultivadas no país. No entanto, maior suscetibilidade à sarna comum foi observada em alguns testes de validação. ‘BRS F183’ foi lançada em 2020 pela Embrapa, como produto do programa de melhoramento desenvolvido pela Embrapa Clima Temperado e Embrapa Hortaliças.

ABSTRACT OBJECTIVE To estimate the evolution of the prevalence of SARS-CoV-2 virus infection among residents aged 18 years or over in the municipality of São Paulo. METHODS This is a population-based household survey conducted every 15 days, between June and September 2020, and January and February 2021. In total, the study comprised 11 phases. The presence of antibodies against SARS-CoV-2 was identified in venous blood using a lateral flow test, Wondfo Biotech. In the last phase, the researchers combined it with an immunoenzymatic test, Euroimmun. The participants also answered a semi-structured questionnaire on sociodemographic and economic factors, and on social distancing measures. Prevalence estimates and the 95% confidence interval were estimated according to regions, Human Development Index, sex, age group, ethnicity, education, income, and variables associated with risk or prevention of infection. To compare the frequencies among the categories of each variable, the chi-square test with Rao-Scott correction was used, considering a significance level of 5%. RESULTS In total, 23,397 individuals were interviewed and had their samples collected. The estimated prevalence of antibodies against SARS-CoV-2 ranged from 9.7% (95%CI: 7.9–11.8%) to 25.0% (95%CI: 21.7–28.7). The prevalence of individuals with antibodies against the virus was higher among black and brown people, people with lower schooling and income, and among residents of regions with lower Human Development Index. The lowest prevalences were associated with recommended measures of disease protection. The proportion of asymptomatic infection was 45.1%. CONCLUSION The estimated prevalence of the infection was lower than the cumulative incidence variation, except for the last phase of the study. The differences in prevalence estimates observed among subpopulations showed social inequality as a risk of infection. The lower prevalence observed among those who could follow prevention measures reinforce the need to maintain social distancing measures as a way to prevent SARS-CoV-2 infection.

OBJECTIVES: To compare demographic/clinical/laboratory/treatments and outcomes among children and adolescents with laboratory-confirmed coronavirus disease 2019 (COVID-19). METHODS: This was a cross-sectional study that included patients diagnosed with pediatric COVID-19 (aged <18 years) between April 11, 2020 and April 22, 2021. During this period, 102/5,951 (1.7%) of all admissions occurred in neonates, children, and adolescents. Furthermore, 3,962 severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) detection samples were processed in patients aged <18 years, and laboratory-confirmed COVID-19 occurred in 155 (4%) inpatients and outpatients. Six/155 pediatric patients were excluded from the study. Therefore, the final group included 149 children and adolescents (n=97 inpatients and 52 outpatients) with positive SARS-CoV-2 results. RESULTS: The frequencies of sore throat, anosmia, dysgeusia, headache, myalgia, nausea, lymphopenia, pre-existing chronic conditions, immunosuppressive conditions, and autoimmune diseases were significantly reduced in children and adolescents (p<0.05). Likewise, the frequencies of enoxaparin use (p=0.037), current immunosuppressant use (p=0.008), vasoactive agents (p=0.045), arterial hypotension (p<0.001), and shock (p=0.024) were significantly lower in children than in adolescents. Logistic regression analysis showed that adolescents with laboratory-confirmed COVID-19 had increased odds ratios (ORs) for sore throat (OR 13.054; 95% confidence interval [CI] 2.750-61.977; p=0.001), nausea (OR 8.875; 95% CI 1.660-47.446; p=0.011), and lymphopenia (OR 3.575; 95% CI 1.355-9.430; p=0.010), but also had less hospitalizations (OR 0.355; 95% CI 0.138-0.916; p=0.032). The additional logistic regression analysis on patients with preexisting chronic conditions (n=108) showed that death as an outcome was significantly associated with pediatric severe acute respiratory syndrome (SARS) (OR 22.300; 95% CI 2.341-212.421; p=0.007) and multisystem inflammatory syndrome in children (MIS-C) (OR 11.261; 95% CI 1.189-106. 581; p=0.035). CONCLUSIONS: Half of the laboratory-confirmed COVID-19 cases occurred in adolescents. Individuals belonging to this age group had an acute systemic involvement of SARS-CoV-2 infection. Pediatric SARS and MIS-C were the most important factors associated with the mortality rate in pediatric chronic conditions with COVID-19.

ABSTRACT The aim of this study was to evaluate the effect of different methods of hydrogen peroxide application on biomass production and quality in soursop seedlings under salt stress. The study was conducted in a greenhouse, in a Psammitic Regolithic Neosol of a sandy-loam texture. The treatments were distributed in a completely randomised design, in a 5 x 4 factorial scheme, with five levels of electrical conductivity for the irrigation water - ECw (0.6, 1.2, 1.8, 2.4 and 3.0 dS m-1) and four methods of hydrogen peroxide application (Control, application by soaking the seeds, application by spraying, and application by soaking and spraying), with two plants per plot and four replications. From 0.6 dS m-1, the salinity of the irrigation water inhibited dry matter production and altered the leaf morpho-physiological index of the soursop seedlings 145 days after sowing. The method of hydrogen peroxide application by soaking the seeds minimised the effect of salt stress on root dry matter production and the quality of the soursop seedlings, and increased leaf succulence, standing out as a tolerance mechanism to salt stress. The application of hydrogen peroxide by soaking the seeds favoured an increase in the root to shoot ratio in soursop exposed to salinity of the irrigation water.
RESUMO Objetivou-se com o presente trabalho, avaliar o efeito de diferentes métodos de aplicação de peróxido de hidrogênio sobre a produção de biomassa e qualidade de mudas de gravioleira sob estresse salino. O estudo foi conduzido em casa de vegetação, utilizando-se de um Neossolo Regolítico Psamitico de textura franco-arenosa. Os tratamentos foram distribuídos em delineamento inteiramente casualizados, em arranjo fatorial 5 x 4, sendo cinco níveis de condutividade elétrica da água de irrigação - CEa (0,6; 1,2; 1,8; 2,4 e 3,0 dS m-1) e quatro métodos de aplicação de peróxido de hidrogênio - (Testemunha; aplicação por embebição das sementes; aplicação por pulverização e aplicação por embebição e pulverização), com duas plantas por parcela e quatro repetições. A salinidade da água de irrigação a partir de 0,6 dS m-1 inibiu a produção de biomassa seca e altera os índices morfofisiológicos foliares de mudas de gravioleira, aos 145 dias após o semeio; O método de aplicação de peróxido de hidrogênio por embebição das sementes minimizou o efeito do estresse salino sobre a produção de biomassa seca radicular e na qualidade das mudas de gravioleira e aumentou da suculência foliar, destacando-se como mecanismo de tolerância ao estresse salino; A aplicação de peróxido de hidrogênio por embebição das sementes favoreceu o aumento da relação raiz/parte aérea da gravioleira quando exposta a salinidade da água de irrigação.

RESULTS In total, 23,397 individuals were interviewed and had their samples collected. The estimated prevalence of antibodies against SARS-CoV-2 ranged from 9.7% (95%CI: 7.9–11.8%) to 25.0% (95%CI: 21.7–28.7). The prevalence of individuals with antibodies against the virus was higher among black and brown people, people with lower schooling and income, and among residents of regions with lower Human Development Index. The lowest prevalences were associated with recommended measures of disease protection. The proportion of asymptomatic infection was 45.1%. CONCLUSION The estimated prevalence of the infection was lower than the cumulative incidence variation, except for the last phase of the study. The differences in prevalence estimates observed among subpopulations showed social inequality as a risk of infection. The lower prevalence observed among those who could follow prevention measures reinforce the need to maintain social distancing measures as a way to prevent SARS-CoV-2 infection.

OBJECTIVE: Coronavirus disease 2019 (COVID-19) is associated with high mortality among hospitalized patients and incurs high costs. Severe acute respiratory syndrome coronavirus 2 infection can trigger both inflammatory and thrombotic processes, and these complications can lead to a poorer prognosis. This study aimed to evaluate the association and temporal trends of D-dimer and C-reactive protein (CRP) levels with the incidence of venous thromboembolism (VTE), hospital mortality, and costs among inpatients with COVID-19. METHODS: Data were extracted from electronic patient records and laboratory databases. Crude and adjusted associations for age, sex, number of comorbidities, Sequential Organ Failure Assessment score at admission, and D-dimer or CRP logistic regression models were used to evaluate associations. RESULTS: Between March and June 2020, COVID-19 was documented in 3,254 inpatients. The D-dimer level ≥4,000 ng/mL fibrinogen equivalent unit (FEU) mortality odds ratio (OR) was 4.48 (adjusted OR: 1.97). The CRP level ≥220 mg/dL OR for death was 7.73 (adjusted OR: 3.93). The D-dimer level ≥4,000 ng/mL FEU VTE OR was 3.96 (adjusted OR: 3.26). The CRP level ≥220 mg/dL OR for VTE was 2.71 (adjusted OR: 1.92). All these analyses were statistically significant (p<0.001). Stratified hospital costs demonstrated a dose-response pattern. Adjusted D-dimer and CRP levels were associated with higher mortality and doubled hospital costs. In the first week, elevated D-dimer levels predicted VTE occurrence and systemic inflammatory harm, while CRP was a hospital mortality predictor. CONCLUSION: D-dimer and CRP levels were associated with higher hospital mortality and a higher incidence of VTE. D-dimer was more strongly associated with VTE, although its discriminative ability was poor, while CRP was a stronger predictor of hospital mortality. Their use outside the usual indications should not be modified and should be discouraged.

ABSTRACT The cultivation of soursop has increased in recent years due to the advance of agribusiness and due to its use by the pharmaceutical industry. As a source of vitamin C, calcium, carbohydrates and antioxidant substances, soursop helps to protect the human body against oxidative stress, acting in the prevention of a series of chronic degenerative disorders. In this context, the objective of present study was to evaluate the effects of foliar sprays with salicylic acid to mitigate the effects of salt stress on the morphophysiology of soursop. The study was conducted in a greenhouse, in a randomized block design and a 5 × 4 factorial arrangement, with five levels of electrical conductivity of irrigation water - ECw (0.8-control; 1.6; 2.4; 3.2 and 4.0 dS m-1) and four concentrations of salicylic acid - SA (0; 1.2; 2.4 and 3.6 mM), with three replicates. Foliar application of SA at concentrations between 1.2 and 1.6 mM mitigated the effects of salt stress on stomatal conductance, CO2 assimilation rate, transpiration and instantaneous carboxylation efficiency of soursop at 480 days after transplanting. Spraying with SA at concentrations between 1.3 and 1.6 mM induced acclimatization to salt stress in soursop plants, since the percentage of intercellular electrolyte leakage was reduced and the growth was favored by the application of SA, even when exposed to salinity. Irrigation with ECw above 0.8 dS m-1 reduced the relative water content in the leaves of soursop cv. Morada Nova.
RESUMO O cultivo da graviola tem aumentado nos últimos anos em função do avanço da agroindústria e pela utilização na indústria farmacêutica. Em razão da fruta ser fonte de vitamina C, cálcio, carboidratos e substâncias antioxidantes, além de auxiliar na proteção contra o estresse oxidativo, atuando na prevenção de uma série de distúrbios crônico degenerativos. Nesse contexto, objetivou-se avaliar os efeitos de pulverizações foliares com o ácido salicílico na mitigação dos efeitos do estresse salino na morfofisiologia da gravioleira. O estudo foi conduzido em casa de vegetação, no delineamento de blocos casualizados e arranjo fatorial 5 × 4, com cinco níveis de condutividade elétrica da água de irrigação - CEa (0,8-controle; 1,6; 2,4; 3,2 e 4,0 dS m-1) e quatro concentrações de ácido salicílico - AS (0; 1,2; 2,4 e 3,6 mM), com três repetições. A aplicação foliar do AS entre as concentrações de 1,2 e 1,6 mM amenizou os efeitos do estresse salino sobre a condutância estomática, a taxa de assimilação de CO2, a transpiração e a eficiência instantânea da carboxilação da gravioleira aos 480 dias após o transplantio. A pulverização com AS com concentrações entre 1,3 e 1,6 mM induziu a aclimatação ao estresse salino na gravioleira, visto que, as plantas tiveram a porcentagem de extravasamento de eletrólitos reduzidos e o crescimento beneficiado pela aplicação de AS, mesmo quando expostas a salinidade. A irrigação com CEa acima de 0,8 dS m-1 reduziu o teor relativo de água nas folhas da gravioleira cv. Morada Nova.

Abstract Background Vascular ultrasonography is the imaging exam of choice for initial screening for left common iliac vein compression, which is an asymptomatic finding that can be detected in up to 25% of some patient samples. Objective To determine, using vascular ultrasonography, whether findings of left common iliac vein compression in asymptomatic women are different when assessed in the prone and standing positions. Methods This is a cross-sectional observational study of 50 adult female volunteers with no symptoms of pelvic venous compression. The parameters assessed with vascular ultrasonography in the prone and standing positions were diameters and maximum velocities of the left common iliac vein at the point at which it crosses behind the right common iliac artery and before this point, in addition to left common iliac vein velocity indices at the crossing. Results Eight cases of significant compression of the left common iliac vein were identified when assessed in prone position (16%) and just two cases (4%) were identified in the standing position. Left common iliac vein diameters were statistically larger (p = 0.002) at the point where it crosses behind the right common iliac artery in the standing position and velocities and velocity indices were statistically higher (p < 0.001) in the prone position. No significant compression of the left common iliac vein was identified in the standing position when velocity indices were normal in the prone position. Conclusions There was no difference in detection of significant compression of the left common iliac vein when assessed in the standing position in comparison with assessment in the prone position. However, the study showed that anatomic compression of the left common iliac vein may be reduced in the standing position.
Resumo Contexto A ultrassonografia vascular é o exame de imagem de escolha para rastreamento inicial da compressão na veia ilíaca comum esquerda, cujo achado assintomático pode ser encontrado em até 25% em algumas casuísticas. Objetivo Identificar, pela ultrassonografia vascular, se há diferença na avaliação da compressão na veia ilíaca comum esquerda em mulheres assintomáticas em decúbito dorsal e ao ortostatismo. Métodos Trata-se de um estudo observacional transversal em 50 mulheres voluntárias, sem sintomas de compressão venosa pélvica. Os parâmetros avaliados pela ultrassonografia vascular em decúbito dorsal e ao ortostatismo foram os diâmetros e as velocidades máximas na veia ilíaca comum esquerda no local do cruzamento com a artéria ilíaca comum direita e antes desse cruzamento, além dos índices de velocidade na veia ilíaca comum esquerda no local do cruzamento. Resultados Foram identificados oito casos de compressão significativa na veia ilíaca comum esquerda na avaliação em decúbito dorsal (16%) e somente dois casos (4%) ao ortostatismo. Os diâmetros na veia ilíaca comum esquerda foram estatisticamente maiores (p = 0,002) no local de cruzamento com a artéria ilíaca comum direita ao ortostatismo, e as velocidades e índices de velocidades foram estatisticamente maiores (p < 0,001) em decúbito dorsal. Não houve identificação de compressão significativa na veia ilíaca comum esquerda em ortostatismo quando os índices de velocidades estavam normais em decúbito dorsal. Conclusão Não houve diferença na detecção de compressão significativa da veia ilíaca comum esquerda ao ortostatismo em relação ao decúbito dorsal; no entanto, o estudo mostrou que pode haver menor compressão anatômica da veia ilíaca comum esquerda em posição ortostática.

OBJECTIVES: To prospectively evaluate demographic, anthropometric and health-related quality of life (HRQoL) in pediatric patients with laboratory-confirmed coronavirus disease 2019 (COVID-19) METHODS: This was a longitudinal observational study of surviving pediatric post-COVID-19 patients (n=53) and pediatric subjects without laboratory-confirmed COVID-19 included as controls (n=52) was performed. RESULTS: The median duration between COVID-19 diagnosis (n=53) and follow-up was 4.4 months (0.8-10.7). Twenty-three of 53 (43%) patients reported at least one persistent symptom at the longitudinal follow-up visit and 12/53 (23%) had long COVID-19, with at least one symptom lasting for >12 weeks. The most frequently reported symptoms at the longitudinal follow-up visit were headache (19%), severe recurrent headache (9%), tiredness (9%), dyspnea (8%), and concentration difficulty (4%). At the longitudinal follow-up visit, the frequencies of anemia (11% versus 0%, p=0.030), lymphopenia (42% versus 18%, p=0.020), C-reactive protein level of >30 mg/L (35% versus 0%, p=0.0001), and D-dimer level of >1000 ng/mL (43% versus 6%, p=0.0004) significantly reduced compared with baseline values. Chest X-ray abnormalities (11% versus 2%, p=0.178) and cardiac alterations on echocardiogram (33% versus 22%, p=0.462) were similar at both visits. Comparison of characteristic data between patients with COVID-19 at the longitudinal follow-up visit and controls showed similar age (p=0.962), proportion of male sex (p=0.907), ethnicity (p=0.566), family minimum monthly wage (p=0.664), body mass index (p=0.601), and pediatric pre-existing chronic conditions (p=1.000). The Pediatric Quality of Live Inventory 4.0 scores, median physical score (69 [0-100] versus 81 [34-100], p=0.012), and school score (60 [15-100] versus 70 [15-95], p=0.028) were significantly lower in pediatric patients with COVID-19 at the longitudinal follow-up visit than in controls. CONCLUSIONS: Pediatric patients with COVID-19 showed a longitudinal impact on HRQoL parameters, particularly in physical/school domains, reinforcing the need for a prospective multidisciplinary approach for these patients. These data highlight the importance of closer monitoring of children and adolescents by the clinical team after COVID-19.

ABSTRACT The search for alternatives that enable the use of saline waters in agriculture has become constant. In this context, the objective was to evaluate the effects of salicylic acid in mitigating salt stress effects on the growth and gas exchange of soursop cv. ‘Morada Nova’. The study was conducted in a greenhouse, in the municipality of Campina Grande - PB, Brazil. Treatments were distributed in randomized blocks, in a 5 x 4 factorial arrangement, corresponding to five levels of electrical conductivity of irrigation water - ECw (0.8; 1.6; 2.4; 3.2 and 4.0 dS m-1) and four concentrations of salicylic acid - SA (0; 1.2; 2.4 and 3.6 mM), with three replicates. Irrigation with saline water compromised the growth and gas exchange of soursop cv. ‘Morada Nova’. However, exogenous application of salicylic acid induced tolerance to salt stress in soursop plants, as their growth, transpiration, stomatal conductance, photosynthesis and instantaneous carboxylation efficiency were favored by the application of salicylic acid, even when exposed to water salinity.
RESUMO A busca por alternativas que possibilitem o uso de águas salinas na agricultura tem se tornado constante. Neste contexto, objetivou-se, avaliar os efeitos do ácido salicílico na mitigação do estresse salino no crescimento e nas trocas gasosas da gravioleira cv. Morada Nova. O estudo foi conduzido em casa de vegetação, no município de Campina Grande - PB. Os tratamentos foram distribuídos em blocos casualizados, em arranjo fatorial 5 x 4, sendo cinco níveis de condutividade elétrica da água de irrigação - CEa (0,8; 1,6; 2,4; 3,2 e 4,0 dS m-1) e quatro concentrações de ácido salicílico - AS (0; 1,2; 2,4 e 3,6 mM), com três repetições. A irrigação com águas salinas comprometeu o crescimento e as trocas gasosas da gravioleira cv. Morada Nova. Entretanto, a aplicação exógena do ácido salicílico induziu a tolerância ao estresse salino a gravioleira, visto que, as plantas tiveram seu crescimento, transpiração, condutância estomática, fotossíntese e eficiência instantânea da carboxilação beneficiadas pela aplicação do ácido salicílico, mesmo quando expostas a salinidade da água.

ABSTRACT The aimed of this study was to evaluate the attenuating action of nitrogen doses on leaf cell membrane damage, dry biomass production and leaf area in the formation of yellow passion fruit seedlings irrigated with saline water. Treatments were arranged in a randomized block design, in split plots, corresponding to five levels of irrigation water salinity (plot) (ECw) (0.3; 1.0; 1.7; 2.4 and 3.1 dS m-1) and five doses of nitrogen fertilization (subplot) (60; 80; 100; 120 and 140% of 300 mg of N dm-3), which were repeated in five blocks. Plants were grown in pots (Citropote®) with a volume of 3,780 mL, which were filled with a mixture of soil, aged bovine manure and sawmill residue (shaving) in a ratio of 2:1:0.5, respectively. Waters with different levels of salinity were applied from 40 to 85 days after sowing, when the plants were in transplanting conditions. At 85 days after sowing, the percentage of cell damage based on electrolyte leakage, variables of dry biomass, leaf area and specific leaf area were evaluated. Increment in irrigation water salinity reduces the biomass accumulation of yellow passion fruit seedlings; The increase in nitrogen dose did not mitigate the effect of salinity, which reduced cell membrane integrity, making the plant more sensitive.
RESUMO Objetivou-se estudar a ação atenuante de doses de nitrogênio sobre o dano à membrana celular das folhas, a produção de fitomassa seca e a área foliar na formação de mudas de maracujazeiro amarelo irrigadas com água salina. Para tanto, foi usado o delineamento experimental em blocos casualizados, com os tratamentos dispostos em parcelas subdivididas, estudou-se cinco níveis de salinidade da água de irrigação (parcela) (CEa) (0,3;1,0; 1,7; 2,4 e 3,1 dS m-1) e cinco doses de adubação nitrogenada (subparcela) (60; 80; 100; 120 e 140%) de 300 mg de N dm-3), que foram repetidos em cinco blocos. As plantas foram cultivadas em citropotes com volume de 3.780 mL, que foram preenchidos com uma mistura de solo, esterco bovino curtido e resíduo de serraria (maravalha) na proporção de 2:1:0,5, respectivamente. A aplicação das águas com diferentes salinidades ocorreu no período de 40 a 85 dias após a semeadura, época em que as plantas estavam em condições de transplante. Aos 85 dias após a semeadura, estudaram-se o percentual de dano celular, por meio do extravasamento de eletrólitos, variáveis de fitomassa seca, a área foliar e área foliar especifica. O incremento na salinidade da água de irrigação reduz o acúmulo de fitomassa das mudas de maracujazeiro amarelo; O aumento na dose de nitrogênio não mitigou o efeito da salinidade, que reduziu a integridade da membrana celular, proporcionando maior sensibilidade à planta.

OBJECTIVES: We designed a cohort study to describe characteristics and outcomes of patients with coronavirus disease (COVID-19) admitted to the intensive care unit (ICU) in the largest public hospital in Sao Paulo, Brazil, as Latin America becomes the epicenter of the pandemic. METHODS: This is the protocol for a study being conducted at an academic hospital in Brazil with 300 adult ICU beds dedicated to COVID-19 patients. We will include adult patients admitted to the ICU with suspected or confirmed COVID-19 during the study period. The main outcome is ICU survival at 28 days. Data will be collected prospectively and retrospectively by trained investigators from the hospital’s electronic medical records, using an electronic data capture tool. We will collect data on demographics, comorbidities, severity of disease, and laboratorial test results at admission. Information on the need for advanced life support and ventilator parameters will be collected during ICU stay. Patients will be followed up for 28 days in the ICU and 60 days in the hospital. We will plot Kaplan-Meier curves to estimate ICU and hospital survival and perform survival analysis using the Cox proportional hazards model to identify the main risk factors for mortality. ClinicalTrials.gov: NCT04378582. RESULTS: We expect to include a large sample of patients with COVID-19 admitted to the ICU and to be able to provide data on admission characteristics, use of advanced life support, ICU survival at 28 days, and hospital survival at 60 days. CONCLUSIONS: This study will provide epidemiological data about critically ill patients with COVID-19 in Brazil, which could inform health policy and resource allocation in low- and middle-income countries.
