Abstract Introduction: patients with COVID-19 undergo changes in leukocyte count, respiratory disorders, and an increase in inflammatory substances. To improve the inflammatory condition, some nutrients can be used, including arginine, omega-3 fatty acids and nucleotides. This study aims to evaluate how oral immunonutrient supplements affects serum C-reactive protein (CRP) levels and lymphocyte count in patients with COVID-19. Methods: in this double-blind clinical trial, we randomized 43 adult patients with COVID-19 to receive a standard high-protein normocaloric supplement (control) or an immunonutrient-enriched supplement (experiment) for 7 days. The primary outcome was to evaluate changes in total lymphocyte count and serum level of CRP. The assessment of risk and nutritional status of these patients was also performed. Results: forty-three patients with mean age of 41.5 (± 1.8) years were followed up, 39.5 % of them women. The mean body mass index was 27.6 (± 0.8) kg/m² and 58.1 % had low nutritional risk. In the experiment group, there was a CRP reduction of 23.6 (± 7.5) mg/L, while in the control branch the decrease was 14.8 (± 12.1) mg/L (p = 0.002). There was an increase in lymphocytes in the experiment group (+367.5 ± 401.8 cells/mm³) and a reduction in the control group (-282.8 ± 327.8 cells/mm³), although there was no statistical significance (p = 0.369). Relative risk (RR) of treatment in reducing CRP by 30 % or more was 4.45 (p < 0.001; 95 % CI, 1.79-11.07). RR in increasing lymphocyte count by 30 % or more was 1.28 (p = 0.327; 95 % CI, 0.67-2.45). Conclusion: we conclude that immunonutrient supplements seem to reduce CRP levels more than standard high-protein normocaloric supplements.

Resumen Introducción: los pacientes con COVID-19 sufren cambios en el recuento de leucocitos, trastornos respiratorios y aumento de sustancias inflamatorias. Para mejorar la condición inflamatoria se pueden usar algunos nutrientes, como la arginina, los ácidos grasos omega-3 y los nucleótidos. Este estudio tiene como objetivo evaluar cómo los suplementos de inmunonutrientes orales afectan a los niveles séricos de proteína C-reactiva (PCR) y al recuento de linfocitos en pacientes con COVID-19. Métodos: en este ensayo clínico doble ciego, aleatorizamos a 43 pacientes adultos con COVID-19 para recibir un suplemento normocalórico estándar alto en proteínas (control) o un suplemento enriquecido con inmunonutrientes (experimento) durante 7 días. El resultado primario fue evaluar los cambios en el recuento total de linfocitos y el nivel sérico de PCR. También se realizó la evaluación del riesgo y el estado nutricional de estos pacientes. Resultados: cuarenta y tres pacientes con edad media de 41,5 (± 1,8) años fueron seguidos, el 39,5 % de ellos mujeres. El índice de masa corporal medio fue de 27,6 (± 0,8) kg/m² y el 58,1 % tenían bajo riesgo nutricional. En el grupo experimental hubo una reducción de la PCR de 23,6 (± 7,5) mg/L, mientras que en la rama de control la disminución fue de 14,8 (± 12,1) mg/L (p = 0,002). Hubo un aumento de linfocitos en el grupo experimental (+367,5 ± 401,8 células/mm³) y una reducción en el grupo de control (-282,8 ± 327,8 células/mm³), aunque no hubo significación estadística (p = 0,369). El riesgo relativo (RR) del tratamiento para reducir la PCR en un 30 % o más fue de 4,45 (p < 0,001; IC 95 %: 1,79-11,07). El RR en el aumento del recuento de linfocitos en un 30 % o más fue de 1,28 (p = 0,327; IC 95 %: 0,67-2,45). Conclusión: se concluye que los suplementos de inmunonutrientes parecen reducir los niveles de PCR más que los suplementos normocalóricos estándar altos en proteína.

Abstract Introduction: glutamine (GLN), the most abundant non-essential amino acid in the plasma, tends to be rapidly depleted in cells in situations of metabolic stress. Some studies have demonstrated the benefits of GLN supplementation on mortality, infection, and length of hospital stay. The objective of this review was to analyze whether parenteral supplementation with GLN has any relevant effect in critically ill surgical patients. Methods: based on a systematic database search, randomized clinical trials (RCTs) published since 1985 were included if they had evaluated the effect of parenteral GLN supplementation in critical surgical patients. The statistical analysis was performed using the RevMan 5.3 software. Results: seven RCTs were eligible for the meta-analysis. Parenteral glutamine supplementation was associated with a non-significant 24 % reduction in mortality (RR = 0.76; 95 % CI: 0.50-1.15). Infections were significantly reduced (RR = 0.60; 95 % CI: 0.45-0.80), and length of hospital stay was 4.09 days shorter (95 % CI: -6.71 to -1.46). Conclusion: parenteral GLN usage in critical surgical patients seems to decrease infection and length of hospital stay, but we could not demonstrate a significant reduction in mortality.

Resumen Introducción: la glutamina (GLN), el aminoácido no esencial más abundante en el plasma, tiende a agotarse rápidamente en las células en situaciones de estrés metabólico. Algunos estudios han demostrado beneficios de la suplementación con GLN en términos de reducción de la mortalidad, las infecciones y la duración de la hospitalización. El objetivo de esta revisión es analizar si la suplementación parenteral de GLN tiene algún efecto relevante para los pacientes quirúrgicos en estado crítico. Métodos: basado en una búsqueda sistemática de bases de datos, se incluyeron ensayos clínicos aleatorizados (ECA) publicados desde 1985 si estos habían evaluado el efecto de la suplementación parenteral de GLN en pacientes quirúrgicos críticos. El análisis estadístico se realizó utilizando el software RevMan 5.3. Resultados: siete ECA fueron elegibles para el metaanálisis. La suplementación parenteral de glutamina se asoció a una reducción no significativa del 24 % en la mortalidad (RR = 0,76; IC 95 %: 0,50-1,15). Las infecciones se redujeron significativamente (RR = 0,60; IC 95 %: 0,45-0,80) y la duración de la estancia de hospitalización fue 4,09 días menor (IC 95 %: -6,71 a -1,46). Conclusión: el uso de GLN parenteral en pacientes quirúrgicos críticos parece disminuir las infecciones y la duración de la estancia hospitalaria, pero no pudimos demostrar una reducción significativa de la mortalidad.

ABSTRACT Grape juices have been valued due to their potential health benefits, which have demanded increased grape productivity and quality. Five grape cultivars grown in Brazil, Isabel Precoce, Carmem, Violeta, Concord and Bordo were evaluated in 2013 and 2014 seasons for bioactive components and also for juice processing quality traits. Production cycle was the longest for Carmem but lower and similar for Violeta, Isabel, Bordo and Concord. Isabel showed higher productivity (5.4 kg∙plant-1) but lowest soluble solids content (16.9 °Brix), anthocyanins (26.7 mg∙100 g-1) and total phenolics (110.7 mg∙100 g-1). The highest anthocyanins contents were observed in Violeta (189.9 mg∙100 g-1) and Bordo (133.8 mg∙100 g-1). These cultivars were also rich in phenolics (356.1 and 239.5 mg∙100 g-1, respectively). The highest anthocyanin and total phenolics concentrations were found in Violeta juice (2.68 and 6.33 g∙L-1) followed by Bordo (1.44 and 2.86 g∙L-1). Isabel juice had the lowest content, 0.14 and 1.29 g∙L-1, respectively. Biogenic amines were found at low concentrations only in the juices. Putrescine and spermidine were the major amines detected in juices. Phenylethylamine was detected only in Bordo juice from 2013 season and tryptamine was detected only in 2014 season. Blends were preferred over varietal juices except for Carmem.

ABSTRACT In the Brazilian Southeast, the production of high quality wines is attained by a new management approach called double pruning. This management changes the harvesting of wine grape (Vitis vinifera L.) from wet summer to dry winter through a two pruning procedures carried out during the year. The first pruning is done during the winter to induce a vegetative cycle (all clusters are removed) and a second pruning is done during the summer to induce the reproductive cycle. In this study, ten different rootstocks were compared in order to optimize yield and wine quality of Syrah vines conducted under autumn-winter season by double pruning approach. Syrah grapevines grafted onto ‘Rupestris du Lot’ and ‘IAC 766’ showed the highest pruning weight, while ‘110 Richter’ and ‘161-49 Courdec’ induced the lowest cane vigor. The average production of two seasons identified ‘IAC 766’, ‘Kober 5BB’ and ‘Rupestris du Lot’ as the most productive rootstocks. In both seasons, the grape quality was more influenced by the plant development status than by rootstocks. ‘Syrah’ wine from vigorous and high yielding rootstocks, ‘IAC 766’ and ‘Rupestris du Lot’, showed satisfactory wine phenolic composition and alcohol/acidity balance. This study showed that vigorous rootstock increased yield without compromising grape and winter wine quality of Syrah grapevines subjected to double pruning management in the Brazilian Southeast.

ABSTRACT O comportamento agronômico da videira Chardonnay, indicada para a produção de vinhos espumantes, está relacionado ao manejo do vinhedo e às condições edafoclimáticas da região de cultivo. O objetivo deste trabalho foi avaliar dois tipos de poda (Cordão Royat e Guyot Duplo) no desenvolvimento vegetativo e produtivo da videira Chardonnay, em região de elevada altitude no Sudeste Brasileiro. Foi utilizado o clone 96 da cultivar Chardonnay, enxertado sobre o porta-enxerto 1103 Paulsen, e sustentado em espaldeira, em um vinhedo comercial localizado a 1.280 m de altitude em Divinolândia (SP). Durante os ciclos de produção de 2014 e 2015, foram avaliados vigor vegetativo, fertilidade de gemas, produção e composição físico-química das bagas. A poda do tipo Royat induziu maior vigor vegetativo e aumentou a fertilidade das gemas, o número de cachos e a produtividade da videira Chardonnay quando comparada à poda Guyot. Apesar do aumento de produtividade, não houve efeito do tipo de poda na qualidade final da uva. Portanto, a escolha do sistema de poda em função das características genéticas da cultivar e sua interação com o ambiente pode proporcionar maior rentabilidade ao vinhedo. Para o cultivo da Chardonnay no Sudeste Brasileiro, com a finalidade de se obterem vinhos espumantes, o sistema Royat é o mais indicado.

ABSTRACT The agronomical responses of Chardonnay, a variety indicated for sparkling wine production, is influenced by the vineyard management and the edaphoclimatic conditions of the region. The objective of this study was to evaluate the effects of two pruning types (Royat and double Guyot) on vegetative and reproductive development of Chardonnay vine growing at high altitude in the Brazilian southeastern region. The experiment was carried out in a commercial vineyard located at 1,280 m of altitude in Divinolândia, São Paulo State, Brazil. The Chardonnay vines (clone 96), grafted onto 1103 Paulsen rootstock and trained in a vertical shoot positioning trellis system, were assessed. Vegetative vigor, bud fruitfulness, production and physicochemical composition of grapes were evaluated during 2014 and 2015 growing seasons. The Royat pruning induced higher vegetative vigor and increased the bud fruitfulness, the cluster number and the productivity of Chardonnay vine when compared to Guyot pruning. Even though the increase on yield was observed, there was no effect of pruning type on grape final quality. Therefore, the choice of pruning method in function of variety genetic characteristics and their interaction with environment can optimize the vineyard profitability. In the Brazilian southeast, the Royat system is the most suitable one to grow Chardonnay for sparkling wines production.

The performance of Syrah grapevine under protected cultivation with different plastic films was evaluated during 2012 and 2013 seasons in South of Minas Gerais State. Agronomical and physiological measurements were done on eight years old grapevines, grafted onto ‘1103 Paulsen’ rootstock cultivated under uncovered conditions, covered with transparent and with diffuse plastic films. Both plastic covers induced the highest shoot growth rate and specific leaf area. The diffuse plastic induced greater differences on leaf area, pruning weight and leaf chlorophyll content as compared to uncovered vines. Grapevines under diffuse plastic also had the lowest rates of photosynthesis, stomatal conductance and transpiration. Leaf starch, glucose and fructose contents were not affected by treatment, but leaf sucrose was reduced by transparent plastic. The leaf and stem water potential were higher under diffuse plastic. In 2013, grapevines under diffuse plastic showed the highest yields mainly due to decreased rot incidence and increased cluster weight. Furthermore, berries under diffuse plastic showed the highest anthocyanins concentration. The use of diffuse plastic induces more agronomical benefits to produce Syrah grape under protected cultivation.

The change of grape (Vitis vinifera) harvest from summer to winter through double pruning management has improved the fine wine quality in southern Brazil. High altitude, late cultivar and grafting combination all need to be investigated to optimize this new viticulture management. For this purpose, this study was carried out during the 2011 and 2012 growing seasons in a high altitude region of the state of Minas Gerais, Brazil, using eight grafting combinations for five year old Cabernet Sauvignon vines. The stem water potential, photosynthetic rate and stomatal conductance were not affected by rootstock type. The rootstocks IAC 766 and 101-14 induced, respectively, the highest and lowest vegetative vigor in Cabernet Sauvignon, as shown by leaf area and pruning weight. In the 2011 growing season, the leaf chlorophyll contents were increased in IAC 766, whereas vines grafted onto 101-14 accumulated more leaf starch, probably due to reduced vegetative and reproductive growth. In general, rootstocks K5BB, 1045P, SO4 and IAC 766 had the highest yield as compared to 1103P and 101-14. Berries from the grapevine with the highest yield did not differ in pH, total soluble solids and acidity. The rootstocks did not influence the anthocyanins and total phenols in both growing seasons. Quality parameters were better in the 2011 than in the 2012 growing season due to better climatic conditions, mainly less rainfall. The best performance of Cabernet Sauvignon was achieved when grafted onto K5BB, 1045P, SO4 and IAC 766 rootstocks.

'Bordô' grapevines (Vitis labrusca) have great relevance to viticulture due to the quality they can impart to wines and juices. However, this cultivar has high variation in yield, ranging from 6 to 11 t ha-1. The use of clones with superior genetic potential related to scions currently marketed may increase crop profitability and revitalize its cultivation. The aim of this study was to evaluate the agronomical responses of twelve clones of the Bordô cultivar selected over a period of 15 years according to yield and quality. The vineyard was planted in 2008. Grape plants were grafted onto '1103 Paulsen' rootstock and trained on vertical shoot positioning. The agronomical evaluations, performed in the 2011, 2012 and 2013 seasons, covered the duration of their phenological cycles, shoot growth, yield per plant, estimated total yield and physicochemical characteristics. Differences were found between clones in terms of phenology, yield components, and berry composition. Clone 6 had the lowest yield, averaging 5.0 t ha-1 whereas clone 13 was the most productive with 14.9 t ha-1. Based on the most productive vineyards in the region (10.8 t ha-1), the adoption of more productive clones can generate an increase in yield of around 38 %.

The aim of this study was to find alternatives to reduce the cost of mass production of the South American fruit fly (A. fraterculus) by looking for locally available products as protein source in the diet of adults to replace the imported product without changing the quality parameters. Two yeast from a Brazilian company were evaluated. The quality parameters showed that the imported hydrolyzed yeast used in the adult diet could be perfectly replaced by the local products tested, with a reduction of over 80% of the cost of the diet. The quality of the produced insects remained the same and there were improvements in some quality parameters such as the volume of eggs produced, number of adults flying and longevity under the stress.

O objetivo deste trabalho foi avaliar a influência de porta-enxertos sobre as características agronômicas, ecofisiológicas e qualitativas da videira 'Syrah' manejada por meio da técnica da dupla poda. As videiras foram enxertadas nos porta-enxertos 'SO4', '110 Richter' e '1103 Paulsen', e sustentadas em sistema espaldeira sem irrigação. Foram avaliadas as características ecofisiológicas, de produção e de composição físico-química das bagas maduras em três safras (2007, 2008 e 2010). Os porta-enxertos não exerceram influência sobre o potencial hídrico de base, que apresentou valores próximos a -0,2 MPa, o que indica que não houve restrição hídrica no solo ao final da maturação (junho). Também não houve diferença significativa quanto à produção. O porta-enxerto '1103 Paulsen' conferiu menor vigor, menor taxa fotossintética e melhores resultados de maturação, para as safras com menores precipitações. Os porta-enxertos '110 Richter' e 'SO4' apresentaram maior vigor nas condições meteorológicas de 2010 e as maiores taxas fotossintéticas para o mesmo período. As condições meteorológicas tiveram efeito significativo na maturação tecnológica e fenólica, com os melhores resultados para os anos mais secos. O porta-enxerto '1103 Paulsen' fornece melhor equilíbrio entre vigor e produção, o que aumenta a qualidade da uva.

The objective of this work was to evaluate rootstock influence on agronomical, ecophysiological and qualitative characteristics of 'Syrah' vines managed by double pruning. Grapevines were grafted onto 'SO4', '110 Richter' and '1103 Paulsen' rootstocks and trained in vertical shoot position, with no irrigation. Ecophysiological characteristics, yield and composition of ripe grapes were evaluated in three crop seasons (2007, 2008 and 2010). Rootstocks did not affect pre-dawn water potential, with values close to -0.2 MPa, indicating that there was no soil water deficit at the end of ripening (June). There was also no significant effect of rootstocks on yield. The rootstock '1103 Paulsen' induced lower vegetative growth, lower photosynthetic rate and the best results for berry maturation for crop seasons with lower amount of rainfall. The rootstocks '110 Richter' and 'SO4' showed higher vigor under the meteorological conditions of 2010 and the greatest photosynthetic rates in the same period. Meteorological conditions significantly affected technological and phenolic ripeness, with best results observed in drought years. The '1103 Paulsen' rootstock provides better balance between vigor and yield, increasing grape quality.

A suscetibilidade a doenças de grande impacto econômico põe em risco a viabilidade econômica da bananicultura. A melhor estratégia para controle destas doenças, do ponto de vista econômico e ambiental, é a utilização de cultivares resistentes. Porém, estas devem apresentar, além de boas características de produtividade, um bom sabor e facilidade para manuseio e transporte como requisitos para aceitação do mercado. Portanto, este trabalho visou a avaliar características pós-colheita do genótipo PA42-44 resistente ao mal-do-panamá, sigatoka-amarela e negra, comparando à cultivar 'Prata-Anã', bastante difundida, porém suscetível às doenças citadas. Para tal, bananas de cada um dos genótipos foram colhidas e armazenadas à temperatura de 22 ± 1°C e umidade relativa de 75 ± 5% até atingirem determinado índice de coloração para avaliação. As bananas foram avaliadas nos índices de coloração 2; 3; 4; 5 e 6, segundo a escala de notas de Von Loesecke. As variáveis avaliadas foram: firmeza, pH, acidez titulável (AT), sólidos solúveis (SS), relação SS/AT e despencamento. Também foi verificado qual dos genótipos amadurece mais rapidamente, analisando a modificação da cor das bananas por 12 dias. Finalmente, foi realizada a análise sensorial para os atributos aparência, aceitabilidade, firmeza e doçura de ambos os genótipos. As bananas PA42-44, quando comparadas à 'Prata-Anã', nos mesmos índices de coloração, encontravam-se em processo mais avançado de amadurecimento. Porém, quando avaliadas em função do período de armazenamento, a 'Prata-Anã' amadureceu mais rapidamente. As bananas PA42-44 são menos firmes e bem mais suscetíveis ao despencamento que as bananas 'Prata-Anã'. Já as características sensoriais dos genótipos foram iguais quanto à preferência.

The production of bananas will always be threatened by diseases of great economical impact that can unable production. The best strategy to control these diseases, economically and environmentally, is the utilization of resistant materials. However, these must have more than good characteristics of production; they should have attractive flavor and easiness in handling and transportation as requisites for market acceptance. Therefore, the objective of this work was the evaluation of post harvest characteristics of the disease resistant genotype PA 42-44 comparing with the 'Prata-Anã' variety commercially accepted, but susceptible to diseases. For that matter, bananas of each genotype were harvested and stored at 22 ± 1°C temperature and 75 ± 5% relative humidity, until they reached the pre-determined color index for evaluation. The bananas were evaluated at the color indexes of 2, 3, 4, 5 and 6 according to the Von Loesecke scale. The variables analyzed were: firmness, pH, titratable acidity (TA), soluble solids (SS), relation SS/TA and finger detachment. It was also studied maturation period through analysis of color alteration of the bananas for 12 days. Finally, a panel test was done for appearance, acceptability, firmness and sweetness for both genotypes. PA42-44 bananas when compared with 'Prata-Anã' bananas in the same coloration index was more ripe. However, when analyzed in relation to storage period 'Prata-Anã' ripened more rapidly. The PA42-44 bananas are less firm and more susceptible to finger detachment than 'Prata-Anã' bananas. The panel test between the genotypes showed similar taste appreciation.
