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.

RESUMO: A indução do parto visa concentrar os nascimentos para melhor acompanhamento das parturientes e primeiros cuidados aos neonatos. Contudo, mesmo que a técnica de indução de parto, com administração de dexametasona, tenha sido descrita com sucesso desde o final da década de 70, existem estudos escassos que relatam a influência desta técnica sobre o parto em ovinos da raça Santa Inês. Dessa forma, o objetivo do estudo foi avaliar a eficácia da dexametasona em duas doses (8 e 16mg), para a indução do parto de ovelhas Santa Inês com 145 dias de gestação e avaliar os seus efeitos nas características de desencadeamento e finalização do parto. Para este estudo foram utilizadas 58 ovelhas, criadas em sistema extensivo nas fazendas experimentais da UFBA, com prenhez confirmada após inseminação artificial em tempo fixo ou monta controlada. Essas fêmeas foram separadas em três grupos, de acordo com a dose de dexametasona administrada (G1 = 0mg, G2 = 8mg e G3 = 16mg). Destes partos nasceram 79 cordeiros. Foram avaliados o período em horas da indução do parto aos nascimentos, a apresentação fetal ao nascimento, assim como o peso da placenta e o período para o delivramento. Os dados foram analisados pelo pacote estatístico Statistical Analysis System (SAS v.9.0®, 2002) sendo considerado para todas as análises o nível de significância de 5%. Os nascimentos dos grupos induzidos ocorreram em média com 48,4±22,1 horas após a indução, enquanto que as fêmeas com parto não induzido pariram em média 131,96±41,9 horas após aplicação do placebo (P<0,05), confirmando a eficácia de ambas as doses para indução do parto. O período da indução até o parto não diferiu (P>0,05) entre as doses utilizadas. Não ocorreram diferenças no parto em relação à estática fetal, tempo para o delivramento e peso da placenta nos diferentes grupos. Com este estudo, conclui-se que a indução de parto em ovelhas aos 145 dias de gestação com oito e 16 mg de dexametasona é uma técnica eficaz e que não altera o trabalho de parto nas ovelhas da raça Santa Inês.

ABSTRACT: The induction of labor aims to concentrate births to follow up better the parturient and the first care to the neonates. However, even if the labor induction technique with dexamethasone administration has been successfully described since the late 1970s, few studies report the technique of birth development and neonatal vitality in Santa Inês sheep. This study aimed to evaluate the efficiency of dexamethasone use in two doses (8 and 16mg) in labor induction of Santa Inês ewes at 145 days of gestation and to evaluate its effects on the birth characteristics. In this study, 58 ewes were used, raised in an extensive system in the experimental farms of UFBA, with confirmation pregnancy after fixed-time artificial insemination or controlled breeding. These female ewes were separated into three groups according to the dose of dexamethasone administered (G1 = 0mg, G2 = 8mg, and G3 = 16mg). From these births, 79 lambs were born. This study analyzed the period from induction of labor to birth, fetal presentation at birth, the weight of the placenta, and the period for placenta expulsion. The data were analyzed by the Statistical Analysis System (SAS v.9.1.3®, 2002), and the significance level considered for all analyzes was 5%. Births of induced groups occurred on average at 48.4±22.17 hours after induction, while the females with non-induced labor gave birth 131.96±41.9 hours on average after the placebo application (P<0.05), confirming the efficiency of both doses for induction of labor. The period from induction to birth did not differ (P>0.05) between the doses used. There were no differences in delivery about the fetal static relation, time to placental attachment, and weight. With this study, it can be concluded that the induction at 145 days of gestation with eight or 16mg of dexamethasone is a useful technique and does not alter the labor in Santa Inês sheep.

New Schiff base compound N, N’-bis-(4-hexadecanate)-salicylethylenediamine (named IM) was synthesized, and characterized via infrared and nuclear magnetic ressonance spectroscopies. IM was tested as corrosion inhibitor and antioxidant in soybean biodiesel. Corrosion studies were developed with AISI 1020 carbon steel in a three-step accelerated corrosion assay and IM inhibitory activity was evaluated using microscopic techiniques: optical microscopy (OM), scanning electron microscopy (SEM) and atomic force microscopy (AFM). In 750 ppm concentration, IM showed better inhibitory activity compared to commercial compounds tert-butylhydroquinone and pyrogallol, reducing root-mean-square roughness (Rq) from 37.8 to 11.7 nm and peak-peak height (PP) from 454.1 to 120.2 nm after 8 days of immersion. Antioxidant studies were conducted using the PetroOXY equipment. In 250 ppm concentration, IM showed better antioxidant activity as metal chelator, reducing biodiesel oxidation induced by copper on biodiesel. In this concentration, IM increased the induction period from 3.0 to 5.8 h. Furthermore, the new Schiff base acts as an oxygen scavanger. This is a great property because it reduces oxygen concentration in biodiesel, reducing metal corrosion reactions.

Using niobium compounds as heterogeneous catalysts in biodiesel production is a promising methodology from economic and environmental viewpoints. However, the application of niobium catalysts still is a challenge due to the high temperatures and pressures for moderate biofuel yields. Therefore, easily handled and applied materials have been developed to optimize biofuel production, which is the goal of this study. Nb2O5 and ammonium niobium oxalate (AmNO) were activated in reflux and ultrasound-assisted system. Nb2O5 showed better activity under reflux, using methanol. The characterizations conclude that the Lewis-acid sites are determinant for higher conversion rather than surface area. AmNO has better activity also in the reflux system at 70 ºC, against 170 ºC for Nb2O5, reaching above 70% conversion. In addition, reactions in ultrasound-assisted systems are also appealing due to the lower time and temperature, with conversion rates above 40%. Both catalysts showed interesting results under milder conditions than those in the literature.

Abstract This paper presents a thermodynamic model developed for a prototype absorption chiller using NH3/LiNO3 with 10 kW of nominal capacity. The study was undertaken using thermodynamic modeling based on the mass and energy balance, takes the overall heat transfer coefficients into consideration and uses the characteristic equation method. First, the results obtained from the thermodynamic modeling developed were compared with those obtained from the characteristic equations of thermal power activation and the cooling capacity. These showed good agreement with the experimental data, there being maximum relative errors of around 5% for most of the operational conditions of the system. Secondly, a parametric analysis was made by altering the variables, such as temperature, mass flow rate, and configuring the heat dissipation that influences the overall performance of the prototype chiller.

RESUMO A erva-mate (Ilex paraguariensis) tem grande importância socioeconômica na agricultura familiar do Sul do Brasil. A principal doença da erva-mate é a podridão-de-raízes causada por Fusarium spp. Pouco se sabe a respeito da fisiologia deste patógeno, principalmente quanto à agressividade associada à produção de enzimas extracelulares. Neste trabalho, avaliou-se a agressividade de isolados de F. oxysporum e F. solani patogênicos à erva-mate e determinou-se as atividades das enzimas extracelulares catalase, lacase, celulase, caseinase, amilase, protease, lipase e pectinases produzidas por Fusarium spp. em meio de cultura. Foram utilizados seis isolados de F. solani e um isolado de F. oxysporum patogênicos à erva-mate. O isolado de F. oxysporum mostrou-se menos agressivo em relação aos demais isolados de F. solani. Todos os isolados de Fusarium spp. produziram, de maneira semiquantitativa, as enzimas extracelulares catalase, lacase, celulase, caseinase, amilase, protease, lipase e pectinases (poligalacturonase e pectato liase). Entretanto, a quantidade produzida de cada enzima foi significativamente diferente entre os isolados. Com exceção das enzimas lacase e poligalacturonase o isolado M7C1 de F. solani exibiu as maiores médias do índice enzimático e foi também o responsável pelo maior percentual de morte de mudas de erva-mate.

ABSTRACT The yerba-mate (Ilex paraguariensis) has great socioeconomic importance on family farming in Southerm Brazil. One of the main yerba-mate disease is root rotting, caused by Fusarium spp. Little is known about the pathogen physiology, especially regarding the aggressiveness associated with the production of extracellular enzymes. On this work, the aggressiveness of isolates of F. oxysporum and F. solani pathogenic to yerba-mate was evaluated and it was determined the activities of extracellular enzymes catalase, laccase, cellulase, caseinase, amylase, protease, lipase and pectinases produced by Fusarium spp. in culture medium. Six isolates of F. solani and one isolate of F. oxysporum pathogenic to yerba-mate were used. The F. oxysporum isolate proved to be less aggressive in relation to the other F. solani isolates. All isolates of Fusarium spp. produced, on a semiquantitative manner, the extracellular enzymes catalase, laccase, cellulase, caseinase, amylase, protease, lipase and pectinases (polygalacturonase and pectate lyase). However, the quantity produced for each enzyme was significantly different among the isolates. With the exception of the laccase and polygalacturonase enzymes, the M7C1 isolate showed the highest enzymatic index and was also responsible for the highest percentage of yerba-mate seedlings death.

The conventional biodiesel process, although it reaches high conversion yields and productivity, faces problems related to the use of homogeneous catalysts. This work aims to study mixtures of calcium oxide (CaO) and niobium oxide (Nb2O5) as the heterogeneous catalyst. It was used a full 23 factorial design with four central points to analyze how the mass percentage of the oxides, the molar ratio of reactants, and the reaction temperature affect the conversion yield to methyl esters. The best conversion yield was found near to 89% using 1.8% of catalyst, a 1:36 oil to methanol ratio and at 77 ºC as reaction temperature. Finally, it was performed a simplified simulation to compare the heterogeneous catalyst process with the conventional process, and an algorithm to compare the effects of the exit streams of each process would have on the environment. The simulations results display a better performance for the heterogeneous catalyst process studied.

ABSTRACT This study analyzes the in vitro antagonistic activity of Trichoderma sp. isolates against Fusarium subglutinans and evaluates the effect of the pine seeds treatment with Trichoderma sp. on the incidence of root rot. Twelve Trichoderma sp. isolates and two F. subglutinans isolates were included in the study. Trichoderma sp. inhibited F. subglutinans mycelial growth through direct contact with hyphae and the production of volatile antifungal compounds. Pine seeds treatment with the antagonist Trichoderma sp. reduced the incidence of root rot, increased the emergence and initial growth in the height of seedlings, and improved seedling health.

ABSTRACT The objective of this study was to assess variations of the condition factor (K1) in relation to the gonadosomatic- RGS and energy reserves (hepatosomatic - RWL and liposomatic - RFB relations) of Leptodactylus macrosternum and their relationship to climate variation in the Northeast of Brazil, Caatinga area, state of Paraiba. The animals were captured fortnightly through active collecting, between January and December 2013. Significant differences were observed in the monthly variations of K1, RGS and RFB indices in male and female L. macrosternum over the months of collection. In males, K1 showed no significant relationship with the other variables. In females, RGS values only show notable correlations with RWF and K1 values. K1 values showed significant correlations with all other weight and length ratios. Climate change in the HFOB region showed significant relationships with the variation of the indexes evaluated, with the exception of RWF. The variation of K1, RGS, RWL and RFB values over the months of collection as well as their relation with the local climatic variation, showed a brief reproductive activity for the species.

O presente trabalho apresenta uma metodologia simples, rápida e de baixo custo para determinação simultânea de paracetamol (PC) e ibuprofeno (IB) em formulações farmacêuticas por voltametria de pulso diferencial usando eletrodo de diamante dopado com boro (BDD). Os analitos apresentaram picos de oxidação definidos em 0,85 V para o PC e 1,72 V para o IB (vs. Ag/AgCl) sobre o eletrodo de trabalho de BDD em meio de uma solução de H2SO4 0,1 mol L-1 com 10% (v/v) de etanol. As curvas de calibração mostraram uma resposta linear para determinação simultânea dos analitos entre 20 a 400 µmol L-1 (r² = 0,999) e os limites de detecção obtidos pelas regressões foram de 7,1 µmol L-1 e 3,8 µmol L-1 para PC e IB, respectivamente. Os estudos de adição e recuperação nas amostras ficaram próximos de 100% e os resultados foram validados por métodos cromatográficos.

This work presents a simple, fast and low-cost methodology for the simultaneous determination of paracetamol (PC) and ibuprofen (IB) in pharmaceutical formulations by differential pulse voltammetry using a boron-doped diamond (BDD) electrode. A well-defined oxidation peak was observed using the BDD electrode for each analyte (0.85 V for PC and 1.72 V for IB (vs. Ag/AgCl)) in 0.1 mol L-1 H2SO4 solution containing 10% (v/v) of ethanol. Calibration curves for the simultaneous determination of PC and IB showed a linear response for both drugs in a concentration range of 20 to 400 µmol L-1 (r² = 0.999), with a detection limit of 7.1 µmol L-1 for PC and 3.8 µmol L-1 for IB. The addition-recovery studies in samples were about 100% and the results were validated by chromatographic methods.

To choose among the variety of oleaginous plants for biodiesel production, the oil content of several matrices was determined through different low-field ¹H nuclear magnetic resonance (NMR) experiments with varied pulse sequences, namely single-pulse, spin-echo, CPMG, and CWFP. The experiments that involved the first three sequences showed high correlation with each other and with the solvent extraction method. The quality of the vegetable oils was also evaluated on the basis of the existing correlation between the T2 values of the oils and their properties, such as viscosity, iodine index, and cetane index. These analyses were performed using HCA and PCA chemometric tools. The results were sufficiently significant to allow separation of the oleaginous matrices according to their quality. Thus, the low-field ¹H NMR technique was confirmed as an important tool to aid in the selection of oleaginous matrices for biodiesel production.
