Resumen En la región semiárida de Paraíba, el caupí es el principal producto de la agricultura familiar. El cultivo tiene baja productividad debido a lluvias irregulares y condiciones climá ticas desfavorables. Además, la productividad también se ve afectada por el uso deficiente de las tecnologías de producción. Con el objetivo de superar estas limitaciones y aumentar la eficiencia de la selección de cultivares superiores, se llevó a cabo un extenso estudio utili zando modelos biométricos en caupí. Este primer trabajo tuvo los siguientes objetivos: i. Cuantificar los efectos directos e indirectos de los componentes primarios y secundarios en la producción de granos; ii. Identificar variables con mayor potencial para la selección de cultivares de caupí en la región semiárida de Paraíba y iii. Determinar las estrategias de selección más adecuadas para el conjunto de variables evaluadas. El experimento se llevó a cabo en un campo experimental en el Centro de Ciencia y Tecnología Agroalimentaria de la Universidad Federal de Campina Grande. Se evaluó la influencia de 6 componentes primarios y 6 componentes secundarios de la producción sobre la variable rendimiento de grano. Los datos se sometieron a ANAVA y se estimaron parámetros genéticos. También se realizaron correlaciones y análisis de ruta. Se identificaron variables con mayor potencial para la selección de cultivares superiores de caupí en la región semiárida de Paraíba. Se encontró que la variable rendimiento de vaina es la más prometedora para la selección de cultivares con mayor rendimiento de grano debido a la magnitud de los efectos fenotípico y genotípico. La selección directa y la selección simultánea son las estrategias más adecuadas para el conjunto de variables evaluadas. Sin embargo, para maximizar las ganancias gené ticas, se continuó el estudio a través de índices de selección.

Abstract In the semi-arid region of Paraíba, cowpea has low productivity due to irregular rainfall and poor use of production technologies. An extensive study aimed at selecting more productive cultivars was conducted using biometric models. This first work had the following objectives: i. Quantify direct and indirect effects of primary and secondary compo nents on grain production; ii. Identify variables with greater potential for cultivar selection in the semiarid region of Paraíba and iii. Determine the most appropriate selection strat egies for the evaluated variables. The experiment was conducted in an experimental field. The influence of 6 primary and 6 secondary production components was evaluated on grain yield. Data were subjected to ANOVA. Genetic parameters, correlations and path analysis were estimated. Given the strong direct phenotypic and genotypic effects, pod yield results the most promising variable for higher grain yield selection. Direct and simultaneous selec tions are the most suitable strategies for the set of evaluated variables. However, further studies on selection indices are necessary to maximize genetic gains.

Resumen En la región semiárida de Paraíba, el caupí (Vigna unguiculata (L.) Walp) es el prin cipal producto de la agricultura familiar. El cultivo tiene baja productividad debido a lluvias irregulares y al uso de cultivares de baja productividad. Con el objetivo de superar estas limitaciones y aumentar la eficiencia de la selección de cultivares superiores, se llevó a cabo un extenso estudio utilizando modelos biométricos en caupí, con los siguientes obje tivos: i. Estimar las ganancias genéticas de los componentes de la producción; ii. Identi ficar el modelo de índice de selección que proporciona las mayores ganancias mediante la selección simultánea de un conjunto de variables y iii. Seleccionar cultivares con mayor productividad. El experimento se llevó a cabo en el campo experimental del Centro de Ciencia y Tecnología Agroalimentaria de la Universidad Federal de Campina Grande. Se evaluaron 13 variables relacionadas con la productividad. Los datos se sometieron a ANOVA y las medias se agruparon según la prueba de Scott y Knott p≤ 0,05. También se estimó el coeficiente de heredabilidad de cada variable. Las ganancias genéticas se estimaron utili zando las siguientes metodologías: respuesta correlacionada, índice de selección clásico, suma de rango e índice basado en las ganancias deseadas. Se encontró que la selección directa del componente de rendimiento de la vaina secundaria proporciona ganancias genéticas significativas en rendimiento de grano. Entre las metodologías utilizadas, el índice de selección clásico proporcionó una mayor distribución de las ganancias genéticas para rendimiento de grano y para los componentes primarios de producción. Estos resultados permiten concluir que los cultivares Costela de vaca, BRS Marataoã y Paulistinha pueden seleccionarse para cultivo y explotación en la región semiárida de Paraíba.

Abstract Low cowpea productivity (Vigna unguiculata (L.) Walp) in the semi-arid region of Paraíba is due, among other factors, to poor-quality cultivars. This research tested biometric models intending to increase productivity of superior cultivars with the following objectives: i. Estimate genetic gains in production components; ii. Identify the selection index model providing the greatest gains through simultaneously selecting a set of variables, and iii. Select cultivars with higher productivity. The experiment was carried out in the experimental field of the Agrifood Science and Technology Center of the Federal University of Campina Grande. Eight cultivars and 13 variables were evaluated. Data were subjected to ANOVA and means were grouped using the Scott and Knott test. Genetic gains were estimated by correlated response, classic selection index, rank sum and index based on desired gains. Direct selection of the secondary pod yield component provides significant genetic gains in main grain yield. Among the methodologies used, the classic selection index provided greater distribution of genetic gains for main grain yield and primary production components. These results allow concluding that Costela de vaca, BRS Marataoã and Paulistinha cultivars should be selected for cultivation and commercial exploitation in the semiarid region of Paraíba.

RESUMO: O presente estudo teve como objetivo avaliar se os índices obtidos com Canopeo e GreenSeeker (NDVI) em Megathyrsus maximum são capazes de estimar altura de plantas, massa de matéria seca, componentes morfológicos e teor de proteína bruta e fibra em detergente neutro em diferentes dias de crescimento. Cinco parcelas de 5 × 25 m de capim M.maximum foram definidas: sub parcelas de 1 × 1 m foram avaliadas a cada três dias, nas quais a pastagem apresenta 3, 6, 9, 12, 15, 18, 21, 24, 27 e 30 dias de rebrota. A sub parcela foi avaliada quanto à altura do dossel e acúmulo de massa. O índice do Canopeo (IC) obtido em maior altura foi menor do que o obtido em menor altura. A maior altura de medição aumentou o NDVI em relação a 0,10 m. Os maiores índices foram observados desde 18 dias de rebrota. Exceto para o IC avaliado a 0,10 m de altura, os índices não foram correlacionados com a composição química da forragem. IC e NDVI correlacionaram-se positivamente com a altura da planta, massa de MS e índice foliar, e negativamente com o índice de colmos. Assim, menores alturas de avaliação para IC e NDVI podem ser um bom preditor da altura da forragem. Valores de 0,83 e 85,8 para NDVI e IC, respectivamente, indicam um momento adequado para o início do pastejo de Megathyrsus maximum.

ABSTRACT: This study determined whether Canopeo and GreenSeeker measurements in Megathyrsus maximus can estimate plant height, dry matter mass, morphological components, and content of crude protein and neutral detergent fiber at different days of growth. Five plots of 5 × 25m M. maximus grass were defined: subplots of 1×1m were evaluated every three days, in which the pasture shows 3, 6, 9, 12, 15, 18, 21, 24, 27, and 30 days of regrowth. The subplot was evaluated for canopy height and mass accumulation. The canopeo index (CI) obtained at a higher height was lower than those obtained at a smaller height. Higher measurement height increased the normalized difference vegetation index (NDVI) relative to 0.10 m. The highest indexes were observed since 18 d of regrowth. Except for the CI evaluated at 0.10 m of height, the indexes were not correlated to the chemical composition of the forage. The CI and NDVI were positively correlated to plant height, dry matter mass, and leaf index, whereas both were negatively correlated with stalk index. Thus, lower evaluation heights for CI and NDVI can be a good predictor of forage height. Values of 0.83 and 85.8 for NDVI and CI, respectively, indicated an appropriate time to start the grazing of M. maximus.

Abstract: Erythrina velutina Willd is a native Fabaceae with wide occurrence, mainly in the Caatinga Domain with multiple uses. This study aimed to compare the vulnerability/tolerance of seeds of four accessions of E. velutina to osmotic stresses. Four replications were conducted with 25 seeds, germinated in osmotic solutions of NaCl or PEG up to -1.73 MPa. Seeds that did not germinate after 14 days were recovered in distilled water. Obtained data were fitted in Boltzmann curves and t50 and synchrony were evaluated. A probit analysis was performed, and hydrotime and halotime models were constructed. In distilled water, the germination curve was similar for all accessions. When the concentration of salt or PEG in the substrate increased, the accessions differentiated into two groups. Two accessions - Jutaí 2012 and Jutaí 2015 - maintained high germination up to -0.86 MPa NaCl, while Caboclo 2008 and Caiçara 2011 accessions presented a lower germination speed. The hydrotime and halotime analyses separated the germination response of accessions according to their physiological quality and tolerance to osmotic and saline conditions. Seeds viability was maintained at both stresses, since germination was reestablished at distilled water, thus constituting a crucial response for this species’ survival and conservation.

Resumo: Erythrina velutina Willd é uma Fabaceae nativa com ampla ocorrência, principalmente no Domínio Caatinga com múltiplos usos. O objetivo deste estudo foi comparar a vulnerabilidade/tolerância de sementes de acessos de E. velutina a estresses osmóticos. Foram semeadas quatro repetições com 25 sementes em soluções osmóticas de NaCl ou PEG até -1,73 MPa. As sementes não germinadas após 14 dias foram recuperadas em água destilada. Os dados obtidos foram ajustados em curvas de Boltzmann e t50 e sincronia foram avaliados. Uma análise probit foi realizada e modelos de hidrotempo e halotempo foram construídos. Em água destilada, a curva de germinação foi semelhante para os acessos. Quando a concentração de sal ou PEG no substrato aumentou, os acessos se diferenciaram em dois grupos. Dois acessos - Jutaí 2012 e Jutaí 2015 - mantiveram alta germinação até -0,86 MPa NaCl, enquanto os acessos Caboclo 2008 e Caiçara 2011 apresentaram menor velocidade de germinação. As análises de hidrotempo e halotempo separaram a resposta germinativa dos acessos de acordo com sua qualidade fisiológica e tolerância às condições osmóticas e salinas. A viabilidade das sementes foi mantida em ambos os estresses, pois a germinação foi restabelecida em água destilada, sendo uma resposta crucial para a sobrevivência e conservação desta espécie.

Resumen: En | Texto: En | PDF: En

Abstract This study aimed to apply selection indexes in situations in which F2 populations and their parents are evaluated simultaneously in field trials to predict population genotypic values and selecting the best populations. Fifteen F2 soybean populations were evaluated for number of days to flowering and to maturity and grain yield. The data was analyzed using restricted maximum likelihood/best linear unbiased prediction (REML/BLUP) to obtain genotypic effects, variance components and accuracies. Four selection methods were compared: genotypic values of the F2 populations (gF2), combined index with the mean genotypic value of parents and F2 population (Ia) and two indexes that add (to gF2 and to Ia) and consider genetic variability within populations (Ib and Ic). The index Ia presented a result similar to that obtained with the gF2 selection method. Selection indexes (Ib and Ic) based on several sources of information were more efficient than selection based on gF2 values only.

Abstract The objective of this work was to evaluate the initial adaptive performance of Israeli mango tree cultivars grown in the submedian region of the São Francisco Valley, Brazil. The experiment was carried out from January 2019 to July 2020 using seedlings of the Omer and Shelly cultivars, at six months after transplanting, at a 3×6 m spacing. The experimental design was randomized complete blocks in a 2×3 factorial arrangement, corresponding to the two Israeli mango tree cultivars and the number of branches after formative pruning (three, four, and five branches), with four replicates. Biometric, biochemical, and photosynthetic variables were analyzed, differing between the evaluation times after pruning. The Omer cultivar is more vigorous than Shelly, and formative pruning with three, four, and five branches is recommended for both mango cultivars under the cultivation conditions of the São Francisco Valley.

Resumo O objetivo deste trabalho foi avaliar o desempenho adaptativo inicial de cultivares de mangueiras israelenses cultivadas na região do Submédio do Vale do São Francisco, Brasil. O experimento foi realizado de janeiro de 2019 a julho de 2020, tendo-se utilizado mudas das cultivares Omer e Shelly, aos seis meses após o transplante, em espaçamento de 3×6 m. O delineamento experimental foi em blocos ao acaso, em arranjo fatorial 2×3, correspondente às duas cultivares de mangueiras israelenses e ao número de ramos após a poda de formação (três, quatro e cinco ramos), com quatro repetições. Foram analisadas variáveis biométricas, bioquímicas e fotossintéticas, que diferiram entre as épocas de avaliação após as podas. A cultivar Omer é mais vigorosa que a Shelly, e a poda formativa com três, quatro e cinco ramos é recomendada para ambas as cultivares de manga nas condições de cultivo do Vale do São Francisco.

Abstract The aim of this study was to explore associated variables with sense of coherence (SOC), and dental environment stress (DES) in a sample of dental students. All undergraduate (n = 474) and graduate (n = 105) dental students enrolled in the first semester of 2020 at a public university in southern Brazil were invited to participate. Data collection was performed by an online questionnaire, which included information related to sociodemographic and educational characteristics, biopsychosocial factors, aspects related to feelings experienced in the COVID-19 pandemic, and the SOC scale. The study outcome (DES) was measured by a validated tool. Linear regression analyses were performed to identify the associations between the outcome and all independent variables. A total of 408 students were included (response rate: 70.5%). The overall mean score of the DES scale was 73.95 (SD: 24.13). Students with higher SOC scores were observed to have significantly lower DES scores (βGRADUATE: -0.376; 95%: -0.482 to -0.271; βUNDERGRADUATE: -0.478; 95%:-0.658 to -0.297). Female undergraduate students (β: 11.788; 95%CI: 7.161–16.415) had higher DES scores compared with undergraduate male students. In addition, the presence of anxiety symptoms when providing dental care to patients with symptoms or suspected COVID-19 infection was associated with higher DES scores (β: 10.460; 95%CI: 5.644–15.277) among undergraduate dental students. The level of stress was higher in non-white undergraduate students than white (β: 8.912; 95%CI: 3.581–14.244). Among both undergraduate and graduate dental students, higher SOC scores were associated with lower DES.

Resumo Os incêndios ocorrem devido às ações antrópicas e causam problemas socioambientais no Nordeste do Brasil (NEB). Portanto, este estudo avaliou a variabilidade espaço-temporal dos focos de calor (FC) nas três mesorregiões climáticas de Alagoas: Sertão, Leste e Agreste Alagoano. Os dados de FC foram obtidos do Banco de Dados de Queimadas (BDQueimadas) entre 1998-2020. A série temporal de FC foi submetida às análises estatísticas descritiva, exploratória e multivariada aplicada aos 102 municípios alagoanos. Com base no agrupamento hierárquico identificaram-se três grupos homogêneos (G1, G2 e G3) no Sertão e dois grupos homogêneos de FC no Agreste e Leste Alagoano (G1 e G2). Alguns municípios não formaram grupos (NA), tais como: Belo Monte (26,83 ± 25,87 focos), Limoeiro de Anadia (54,48 ± 38,65 focos), Penedo (262,83 ± 183,80 focos) e Coruripe (553 ± 369,40 focos). A variabilidade interanual dos FC em Alagoas está associada com atividades agrícolas, desmatamento, novas áreas para a criação de animais e colheita da cana-de-açúcar. Na avaliação espacial via densidade de FC por município utilizou-se o período total (1998-2020) e os anos de destaque na série temporal (2012 e 2019). O maior registro de densidade de FC no período total encontra-se na mesorregião do Leste Alagoano e não se descarta que os anos em destaque sejam influenciados pela ocorrência de seca e períodos de estiagens em Alagoas.

Abstract Fires occur due to anthropic actions and cause socio-environmental problems in Northeast Brazil (NEB). Therefore, this study evaluated the spatiotemporal variability of fire focis (FF) in the three climatic mesoregions of Alagoas: Arid Zone, East and Hinterland Alagoano. FF data were obtained from the Queimadas Database (BDQueimadas) between 1998-2020. The FF time series was submitted to descriptive, exploratory, and multivariate statistical analysis applied to 102 municipalities in Alagoas. Based on the hierarchical grouping, three homogeneous groups were identified (G1, G2 and G3) in the Arid Zone and two homogeneous groups of FF in the Hinterland and East Alagoas (G1 and G2). Some municipalities did not form groups (NA), such as: Belo Monte (26.83 ± 25.87 foci), Limoeiro de Anadia (54.48 ± 38.65 foci), Penedo (262.83 ± 183.80 foci) and Coruripe (553 ± 369.40 foci). The interannual FF variability in Alagoas is associated with agricultural activities, deforestation, new areas for animal husbandry and sugarcane harvest. In the spatial evaluation via FF density per municipality, the total period (1998-2020) and the years highlighted in the time series (2012 and 2019) were used. The highest FF density record in the total period is found in the East Alagoas mesoregion and it is not ruled out that the highlighted years are influenced by the occurrence of drought and dry periods in Alagoas.

ABSTRACT BACKGROUND: Acute kidney injury (AKI) is a frequent complication during the postoperative period following liver transplantation. Occurrence of AKI in intensive care unit (ICU) patients is associated with increased mortality and higher costs. OBJECTIVE: To evaluate occurrences of moderate or severe AKI among patients admitted to the ICU after liver transplantation and investigate characteristics associated with this complication. DESIGN AND SETTING: Single-center retrospective cohort study in a public hospital, Belo Horizonte, Brazil. METHODS: Forty-nine patients admitted to the ICU between January 2015 and April 2017 were included. AKI was defined from a modified Kidney Disease Improving Global Outcomes (KDIGO) score (i.e. based exclusively on serum creatinine levels). RESULTS: Eighteen patients (36.7%) developed AKI KDIGO 2 or 3; mostly KDIGO 3 (16 out of the 18 patients). Lactate level within the first six hours after ICU admission (odds ratio, OR: 1.3; 95% confidence interval, CI: 1.021-1.717; P = 0.034) and blood transfusion requirement within the first week following transplantation (OR: 8.4; 95% CI: 1.687-41.824; P = 0.009) were independently associated with development of AKI. Patients with AKI KDIGO 2 or 3 underwent more renal replacement therapy (72.2% versus 3.2%; P < 0.01), had longer hospital stay (20 days versus 15 days; P = 0.001), higher in-hospital mortality (44.4% versus 6.5%; P < 0.01) and higher mortality rate after one year (44.4% versus 9.7%; P = 0.01). CONCLUSION: Need for blood transfusion during ICU stay and hyperlactatemia within the first six postoperative hours after liver transplantation are independently associated with moderate or severe AKI. Developing AKI is apparently associated with poor outcomes.

ABSTRACT Thermal treatment can modify undesirable characteristics of some woods, dimensional instability, and excessive water adsorption. The present research work aimed to assess the effect of thermal treatment on the physical properties of clone GG100 Eucalyptus wood. Wood samples were obtained from 9 year-old trees. Samples were subjected to three types of thermal treatment (T1, T2, and T3). In T1, the wood was kept in a laboratory kiln at 100 °C for 180 min. In T2, hydrothermal treatment was performed in an autoclave at 120 °C for 120 min. In T3, the combined autoclave and laboratory kiln treatments were employed. The properties evaluated were apparent density (ρa); mass loss (ML); longitudinal (βl), radial (βr), tangential (βt), and volumetric shrinkage (βv); anisotropic factor; and equilibrium moisture content. The treatments caused a decrease of ρa and increase of ML. The Equilibrium Moisture Content (EMC) was lowest for T3, and had a negative correlation with ML, βt, and ∆v. The Pearson correlation analysis indicated the results of the thermal treatments were similar, but T1 presented the lowest variation of the physical properties compared to the other treatments, giving it the best predictability for practical uses.

Resumen: En | Texto: En | PDF: En

Abstract Aim: To determine the somatotype profile and level of physical activity in older adults. Methods: Seventy-two older adults were divided into two groups: frail (F = 33) and non-frail (NF = 39). Frailty status was determined using the Tilburg Frailty Indicator (TFI), somatotype using the Heath and Carter method, and physical activity by the International Physical Activity Questionnaire (IPAQ). Results: Somatotype analysis showed a predominance of endomorphy (F = 6.54 ± 1.65 vs NF = 6.12 ± 2.07 p ≤ 0.350) followed by mesomorphy (F = 3.44 ± 1.62 vs NF = 3.15 ± 2.19, p ≤ 0.531) and ectomorphy (F = 0.82 ± 0.99 vs NF = 0.95 ± 0.86 p ≤ 0.163), but no significant differences were observed between groups. Regarding PA, twenty-eight participants (84.7%) of the F group were classified as sedentary and insufficiently active and twenty-one (53.8%) of NF were classified as active and very active. This difference in PA explains the higher total energy expenditure found in NF (median 1,087.43; IAQ = 3,954.30) when compared to F (median = 0.0; IAQ = 462.64 p ≤ 0.001). The frailty group presented a higher endomorphic component as well as lower levels of physical activity and energy expenditure. Conclusion: Endomorphy was the predominant somatotype in F and NF older adults, followed by mesomorphy and actomorphy this profile can affect activities of daily living, functional capacity, and independent living and be associated with chronic diseases.

Resumen: En | Texto: En | PDF: En

ABSTRACT Objective To evaluate the predictive value of positron emission computed tomography or magnetic resonance (PET-CT and PET-MRI) using gallium-68-labeled prostate-specific membrane antigen (68Ga-PSMA) in lymph node involvement in prostate cancer. Methods A retrospective study comprising 91 patients diagnosed with prostate cancer between 2016 to 2020, who underwent 68Ga-PSMA PET-CT or PET-MRI for staging before prostatectomy. The patients were divided into Group 1, with 65 patients with satisfactory pathological lymph node analysis, and Group 2, with 91 patients representing the sum of patients with pathological lymph node analysis and those with postoperative prostate-specific antigen within 60 days after surgery. Receiver Operating Characteristic curves were used to assess accuracy of predictive capacity of imaging exams for lymph node involvement. Results Regarding local clinical staging, the groups showed similar results, and 50% were classified as staging T2a. The accuracy of 68Ga-PSMA PET-CT for prostate cancer lymph node staging was 86.5% (95%CI 0.74-0.94; p=0.06), with a sensitivity of 58.3% and specificity of 95%. The accuracy of 68Ga-PSMA PET-MRI was 84.6% (95%CI 0.69-0.94; p=0.09), with a sensitivity of 40% and specificity of 100%. Considering both 68Ga-PSMA PET-CT and PET-MRI, the accuracy was 85.7% (95%CI 0.76-0.92; p=0.015), with sensitivity of 50% and specificity of 97%. Conclusion The imaging tests 68Ga-PSMA PET-CT and PET-MRI were highly accurate to detect preoperative lymph node involvement, and could be useful tools to indicate the need for extended lymph node dissection during radical prostatectomy.
