Grafting of Australian purple passion fruit progenies in different native species

O maracujá-roxo (Passiflora edulis), apesar de ser desconhecido no Brasil, pode tornar-se numa fonte de renda alternativa para o agricultor, devido à boa remuneração e aceitação da fruta in natura no mercado europeu. Com o objetivo de avaliar a produção de mudas clonais de maracujá-roxo provenientes da Austrália, foi realizado um experimento no Setor de Fruticultura da Universidade de Brasília entre os meses de maio de 2005 e fevereiro de 2006. O delineamento experimental utilizado foi o de blocos casualizados, com 3 repetições, em arranjo fatorial 7 x 2 x 3, sendo sete porta-enxertos, duas variedades-copa e três épocas de avaliação. A parcela foi formada por 3 plantas úteis. Utilizaram-se como porta-enxertos (PE) as espécies P. serrato digitata, P. nitida, P. coccinea, P. quadrangularis, P. edulis e P. edulis f. flavicarpa híbrido 'EC-2-0' e o híbrido P. coccinea X P. setacea, e como copa (CP), as variedades '96A' e '25' de maracujazeiro-roxo. As estacas enraizadas foram transferidas para sacolas plásticas e mantidas sob nebulização intermitente. A enxertia foi efetuada 30 dias após. As avaliações do índice de pegamento foram efetuadas aos 31 e 61 dias após a enxertia (DAE). As combinações CP/PE (entre "25" e "96 A" X P. nitida), seguidas das combinações ("25" e "96 A" X P. edulis f. flavicarpa híbrido 'EC-2-0'), com 100%, 90%, 90% e 80%, respectivamente, obtiveram alto índice de pegamento aos 61 DAE. A produção de mudas de maracujazeiro-roxo enxertadas nas espécies de maracujazeiro silvestres e comerciais P. nitida, P. quadrangularis, P. edulis f. flavicarpa híbrido 'EC-2-0' e P. edulis é viável do ponto de vista técnico, pois não ocorreram problemas de incompatibilidade, e os enxertos apresentaram alta taxa de pegamento.Purple passion fruit (Passiflora edulis), even though is unknown in Brazil, can be an alternative income for the farmers due to good price and acceptance by the European market. Aiming to evaluate the production of clonal nursery plants of Australian purple passion fruit it was realized at the Fruit Section of University of Brasília an experiment from May 2005 to February 2006. Randomized blocks were used with 3 replications in a factorial arrangement 7 x 2 x 3 with 7 rootstock, 2 varieties and 3 periods of evaluation, where each parcel had 3 plants. P. edulis f. flavicarpa, P. serrato digitata, P. nitida, P. coccinea, (P. coccinea X P. setacea), P. quadrangularis, P. edulis e P. edulis f. flavicarpa 'EC-2-0' were used as rootstock and as a scion the purple passion fruit '96A' and '25' from Australia. The rooted rootstock was transferred to plastic bags and kept under misting condition and grafted 30 days later. The rooting success rate was evaluated 31 and 61 days after grafting (DAG). The scion/rootstock combination ("25" and "96 A" X P. nítida) followed by ("25" and "96 A" X P. edulis f. flavicarpa 'EC-2-0') with 100%, 90%, 90% and 80%, respectively, achieved high success rate 61 DAG. The production of purple passion fruits grafted onto native and commercial species as rootstock P. nitida, P. quadrangularis, P. edulis f. flavicarpa 'EC-2-0' and P. edulis is viable since there is no evidence of incompatibility and the grafted plants showed high percentage of success rate

Rationale, study design, and analysis plan of the Alveolar Recruitment for ARDS Trial (ART): Study protocol for a randomized controlled trial

Background: Acute respiratory distress syndrome (ARDS) is associated with high in-hospital mortality. Alveolar recruitment followed by ventilation at optimal titrated PEEP may reduce ventilator-induced lung injury and improve oxygenation in patients with ARDS, but the effects on mortality and other clinical outcomes remain unknown. This article reports the rationale, study design, and analysis plan of the Alveolar Recruitment for ARDS Trial (ART). Methods/Design: ART is a pragmatic, multicenter, randomized (concealed), controlled trial, which aims to determine if maximum stepwise alveolar recruitment associated with PEEP titration is able to increase 28-day survival in patients with ARDS compared to conventional treatment (ARDSNet strategy). We will enroll adult patients with ARDS of less than 72 h duration. The intervention group will receive an alveolar recruitment maneuver, with stepwise increases of PEEP achieving 45 cmH(2)O and peak pressure of 60 cmH2O, followed by ventilation with optimal PEEP titrated according to the static compliance of the respiratory system. In the control group, mechanical ventilation will follow a conventional protocol (ARDSNet). In both groups, we will use controlled volume mode with low tidal volumes (4 to 6 mL/kg of predicted body weight) and targeting plateau pressure <= 30 cmH2O. The primary outcome is 28-day survival, and the secondary outcomes are: length of ICU stay; length of hospital stay; pneumothorax requiring chest tube during first 7 days; barotrauma during first 7 days; mechanical ventilation-free days from days 1 to 28; ICU, in-hospital, and 6-month survival. ART is an event-guided trial planned to last until 520 events (deaths within 28 days) are observed. These events allow detection of a hazard ratio of 0.75, with 90% power and two-tailed type I error of 5%. All analysis will follow the intention-to-treat principle. Discussion: If the ART strategy with maximum recruitment and PEEP titration improves 28-day survival, this will represent a notable advance to the care of ARDS patients. Conversely, if the ART strategy is similar or inferior to the current evidence-based strategy (ARDSNet), this should also change current practice as many institutions routinely employ recruitment maneuvers and set PEEP levels according to some titration method.Hospital do Coracao (HCor) as part of the Program 'Hospitais de Excelencia a Servico do SUS (PROADI-SUS)'Brazilian Ministry of Healt

Prevalence, associated factors and outcomes of pressure injuries in adult intensive care unit patients: the DecubICUs study

Funder: European Society of Intensive Care Medicine; doi: http://dx.doi.org/10.13039/501100013347Funder: Flemish Society for Critical Care NursesAbstract: Purpose: Intensive care unit (ICU) patients are particularly susceptible to developing pressure injuries. Epidemiologic data is however unavailable. We aimed to provide an international picture of the extent of pressure injuries and factors associated with ICU-acquired pressure injuries in adult ICU patients. Methods: International 1-day point-prevalence study; follow-up for outcome assessment until hospital discharge (maximum 12 weeks). Factors associated with ICU-acquired pressure injury and hospital mortality were assessed by generalised linear mixed-effects regression analysis. Results: Data from 13,254 patients in 1117 ICUs (90 countries) revealed 6747 pressure injuries; 3997 (59.2%) were ICU-acquired. Overall prevalence was 26.6% (95% confidence interval [CI] 25.9–27.3). ICU-acquired prevalence was 16.2% (95% CI 15.6–16.8). Sacrum (37%) and heels (19.5%) were most affected. Factors independently associated with ICU-acquired pressure injuries were older age, male sex, being underweight, emergency surgery, higher Simplified Acute Physiology Score II, Braden score 3 days, comorbidities (chronic obstructive pulmonary disease, immunodeficiency), organ support (renal replacement, mechanical ventilation on ICU admission), and being in a low or lower-middle income-economy. Gradually increasing associations with mortality were identified for increasing severity of pressure injury: stage I (odds ratio [OR] 1.5; 95% CI 1.2–1.8), stage II (OR 1.6; 95% CI 1.4–1.9), and stage III or worse (OR 2.8; 95% CI 2.3–3.3). Conclusion: Pressure injuries are common in adult ICU patients. ICU-acquired pressure injuries are associated with mainly intrinsic factors and mortality. Optimal care standards, increased awareness, appropriate resource allocation, and further research into optimal prevention are pivotal to tackle this important patient safety threat

A progênie MAR20#06 foi a que apresentou a maior porcentagem da massa de frutos da cor amarela. A progênie MAR20#19 apresentou a maior produtividade de frutos de classificação primeira. Para a classificação de frutos com o tamanho 1B, a progênie com a maior produtividade foi a MAR20#15. A progênie PES9 apresentou a maior massa média de frutos de 1A 164,84 g. Na avaliação de doenças em condições de campo a progênie MAR20#29 foi o que apresentou a maior severidade média da bacteriose e a progênie MAR20#29 a que apresentou a maior incidência em 2008 e 2009. A progênie MAR20#24 apresentou em 2009 uma severidade de 3,15% sendo a maior severidade da bacteriose entre as progênies. Todas progênies apresentaram-se moderadamente susceptíveis (MS) em 2008. Em 2009 as progênies MAR20#40, MAR20#24, MAR20#6, FB200 e Redondão apresentaram-se suscetíveis (S) e o restante das progênies apresentaram-se moderadamente suscetíveis (MS) a bacteriose. Para a severidade da septoriose em 2008, não houve diferença significativa, entre as progênies. As progênies FB200 e MAR20#12 apresentaram as maiores severidades da septoriose em 2009. Em 2009, as progênies MAR20#34 e MAR20#49 apresentaram as maiores incidências e severidades da verrugose. Em 2008, todas progênies apresentaram-se moderadamente suscetíveis (MS) e em 2009, as progênies MAR20#15, Roxo e MAR20#1 apresentaram-se moderadamente suscetíveis e o restante das progênies apresentaram-se suscetíveis a verrugose. A progênie EC 3 0 apresentou a maior incidência e a maior severidade do vírus em 2008. A progênie MAR20#15 apresentou a maior severidade do vírus em 2009. Todas as progênies apresentaram-se suscetíveis a virose nos dois anos de avaliação.

However it has serious fitossanitary problems. This work was carried out in order to evaluate passion fruit progenies and reaction to the Cowpea aphid-borne mosaic vírus CABMV, the antracnose (Colletotrichum gloeosporioides), verrugose (Cladosporium herbarum) e a bacteriose (Xanthomonas axonopodis pv. passiflorae) in the federal district. Three experiments were performed. The first one was carried out at Agua Limpa’s farm in Federal Districte to evaluate the yield and reaction of passion fruits progenies to the diseases in 2008 and 2009. The experiment consisted of 26 treatments in randomize complete block design, with 4 replications in plots with 8 plants. Twenty six progenie were assessed: FB-200, FB100, MSCA, Rubi gigante, Redondão, Roxo australiano, PES9, EC-3-0, ECL-7, Gigante Amarelo MAR20#12, MAR20#10, MAR20#41, MAR20#40, MAR20#24, MAR20#2005, MAR20#39, MAR20#1, MAR20#15, MAR20#44, MAR20#19, MAR20#6, MAR20#29, MAR20#34, MAR20#21 e MAR20#49. A harvesting 41 times fruit were evaluated for: yield (Kg/ha), average fruit weight, number of fruits and peel colors. The highest yield were obtained for the progenie MAR20#15 (29.082 kg/ha). This progenies showed the most yield of yellows peel color. The progenies MAR20#15, Redondão, MAR20#01 e ECL 7 were the most productivities in the first 12 months of evaluate. The biggest yield of 2A fruits was observed for the genotype Redondão, 2.836,04 kg/ha. The progenies MAR20#19 showed the biggest average fruit weight of 2A yellow, 226,38g. All the progenies had a production of yellow peel fruit color bigger than pink and purple. The progenie PES9 showed the biggest average weight for the 1A (164,84g) and 1B (129,36g) yellow fruit peel color. Positives correlation were observed between yellow yield fruits and general yield, yield of with percentage of purple fruits, general yield with number of 1B fruits and general yield with yield of fruits 1B. ). The incidence and severity was determinated with diagramatics scale. The progenie MAR20#29 (0,89%), showed the biggest severity for the bacteriosis and the the matirials MAR20#41 (0.34%) e PES 9 (0,29%) had the smaller results to severity. The PES 9 had the smaller progress for the bacterial disease in 2008 and the MAR20#2005 in 2009. In the first year of evaluate, 80,77% of the progenies were considerate moderately susceptible and in the second year all the progenies were susceptible. The progenie MAR20#41 showed the smaller progress to the septoriosis disease in the 2008. In 2009, the progenie MAR20#44 had the smaller one of this disease. The progenie MAR20#44 had the most interesting result of verrugosis disease progress in 2008 and 2009 the MAR20#15 showed the smaller results for this parameter. The most interesting result of virus progress was observed for the progenie MAR20#29 in 2008 and the MAR20#49 in 2009. The second experiment used the clones (propagated asexuality by stake) and the third used the seeds (sexual propagation) of the genotypes cultivated in the Agua limpa’s farm. Two experiments were carried out in the Experimental Area of University of Brasilia to evaluate and select passion fruit progenies with resistance to the antracnosis, verrugosis, bacteriosis and the woodiness virus diseases under greenhouse condictions. The first experiment used stakes (asexuality propagation) colected in the field of Água Limpa’s farmsteads. The progenies used in this experiments were: selection MAR 20#2005, 20#34, 20#06, 20#49 e 20#19, Redondão Gigante Amarelo, Rubi Gigante, MSCA, ECL 7, GA2 e FB200. It was used a experimental design in randomized block, with 12 treatments (progenies), 4 replications, in plots with 6 plants for replication. The progenies Redondão and MAR 20#49 showed the samallers incidences, 68,93 % and 69,64 % to the anatracnosis disease. However the progenie MAR 20#06 showed the highest incidence to this disease, 100%. The MAR20#34, MAR20#06, Redondão and MAR20#49 was considerate moderately resistent, FB200 highly susceptible and all the orders progenies was susceptible to the antracnosis. The progenies Redondão, MAR20#2005, FB200 e MAR20#16 were considerate resistant (R) to the verrugosis and the orders progenies were moderately resistant (MR). The second experiment used the seeds collected of the plants in the field of Agua Limpa’s farm. The progenies used were: selection MAR, 20#01, 20#05, 20#12, 20#15, 20#19, 20#21, 20#36, 20#40, 20#2005, 20#03, 20#06, 20#09, 20#10, 20#24, 20#34, 20#39, 20#46, 20#23 e 20#41, GA2, AR01, AR02, FP01, EC RAM, FB100, MSCA, Rubi gigante, Redondão, Roxo australiano, PES9, EC-3-0, ECL-7, Gigante amarelo, A 09 1, ECL 7 1, A 09 2, FB 200 1, FB 200 2, RED 1, PL1, PL2, PL3, PL4, PL5 e PL7. It was used an experimental design in randomized blocks with 24 treatments (progenies), 4 replication, in plots with 6 plants. The progenies Redondão, MAR20#34 e MAR20#03 were considerate susceptible to the verrugosis and all the orders were moderately resistant to this disease. With the bacterial inoculation, the progenies MAR20#39, GA2 and PL5 were considerate susceptible (S) and the orders were moderately susceptible (MS). In the virus evaluation, all the progenies were moderately susceptible

O presente trabalho teve como objetivo avaliar a produtividade de 14 genótipos cultivados no Distrito Federal. Utilizou-se o delineamento de blocos casualizados, com quatro repetições, 14 tratamentos (genótipos), 8 plantas úteis por parcela. Foram avaliados os 14 genótipos: [PCF-2, EC-RAM, MAR 20#03, MAR 20#09, MAR 20#23, MAR 20#36, MAR 20#46, AR-01, AR-02, Yellow Master FB-200, FP-01, RC-3, GA2, AP-1], totalizando 1.111 plantas por hectare. Após vinte colheitas (período de 9 meses), foram avaliadas as seguintes características: produtividade (kg/ha), massa média de frutos (g), número de frutos e coloração da casca. Na avaliação geral, houve maior rendimento dos genótipos, PCF-2 com 15,8 t/ha, EC-RAM 13,9 t/ ha, FP-01 12,4 t/ha e o AR-01 com 12,3 t/ha. Dos 14 genótipos avaliados, 2 produziram mais que a média nacional de 13 t/ha/ano em 2008 (Banco de dados do IBGE, 2008). A massa média dos frutos variou de 105g para o PCF-2 a 192g para o genótipo AR-01. O número de frutos variou de 33.666 frutos/ha, no genótipo RC 3, a 142.791 frutos/ha no genótipo PCF-2. Todos os genótipos apresentaram maior produção de frutos amarelos, seguido de frutos de cor rosa e de cor roxa.The present work had the objective to evaluate the yield of 14 genotypes cultivated in Brasília. A design with randomized blocks with four repetitions, 14 treatments (genotypes) and 8 plants per plot was used. Fourteen genotypes were assessed: [PCF-2, EC-RAM, MAR 20#03, MAR 20#09, MAR 20#23, MAR 20#36, MAR 20#46, AR-01, AR-02, Yellow Master FB-200, FP-01, RC-3, GA-2, A-1], totalizing 1.111 plants per hectare. Supplementary irrigation was performed. The parameters analyzed, after twenty harvests or 9 months were: yield (kg/ha); average fruit weight, number of fruits and peel color. In the general evaluation, there was a highest yield of genotypes PCF-2 with 15.8 t/ha, EC-RAM 13.9 with t/ha, FP-01 with 12.4 t/ha and o AR-01 with 12.3 t/ha. Among the 14 genotypes evaluated, 2 produced more than the national average of 13 t/ha/year in 2008 (IBGE data, 2008). The average fruit weight ranged from 105g for PCF-2 to 192g for genotype AR-01. These results are to be considered outstanding when compared to other works. The number of fruits ranged from 33,666 fruits/ha in genotype RC-3 to 142,791 fruits/ha in PCF-2. All genotypes showed larger production of yellow fruits, followed by pink and purple fruits

Physical-chemical characteristics of five genotypes of yellow passion fruit cultived in Brasília

O objetivo deste trabalho foi de avaliar as características físico-químicas de cinco genótipos de maracujazeiro-azedo cultivado no Distrito Federal nas épocas de fevereiro, março e abril de 2005. O experimentofoi conduzido na área experimental da Fazenda Água Limpa da UnB, Brasília-DF. Utilizou-se o delineamento em blocos casualizados, com quatro repetições, cinco genótipos, três épocas de avaliação e sete plantas úteis por parcela. Foram avaliados os cinco genótipos: Rubi-Gigante, EC-3-0, EC-L-7, Redondão e Gigante-Amarelo. Os frutos produzidos em abril/2005 apresentam maior comprimento, massa fresca do fruto, da polpa, do suco, acidez titulável, pH e número de sementes. O genótipo Rubi-Gigante apresentou frutos com menor comprimento e maior teor de sólidos solúveis. Os genótipos Redondão e Rubi- Gigante apresentaram as menores relações comprimento/diâmetro. Os genótipos Gigante- Amarelo e Redondão apresentam frutos com menor espessura da casca e maior cavidade ovariana e, consequentemente, maior quantidade de polpa. Este último genótipo também obteve frutos com maior diâmetro, teor de sólidos solúveis e menor pH, sendo esta última característica importante para o processamento, pois frutos com elevada acidez conferem uma diminuição na adição de acidificantes no suco. O formato alongado predomina nos frutos dos cinco genótipos, nas três épocas analisadas.The aim of this work was to evaluate the physical-chemical characteristics of five genotypes of passion fruit cultived in Brasília in three seasons: February, March and April of 2005. The experiment wascarried out in the experimental area of the Água Limpa Farm of the UnB, Brasília-DF. It was used the delineation blocks with four repetitions, five genotypes, three evaluation periods and seven useful plants per share. The five genotypes were evaluated: Rubi Gigante, EC-3-0, EC-L-7, Redondão and Gigante Amarelo. The fruits produced on April/2005 present greater length, fresh fruit of mass, pulp, and juice, titrable acidity, pH and number of seeds. Genotype Rubi Gigante presents fruits with lesser length and highest soluble solids. Genotypes Redondão and Gigante Amarelo present fruits with lesser relation length/diameter. The genotypes Gigante Amarelo and Redondão consequently present fruits with a lesser thickness of the rind and the highest ovarian socket, with a highest amount of pulp. This last genotype also got fruits with the highest diameter, soluble solid and lower pH. This characteristic is important for processing; therefore fruits with high acidity present a reduction in the addition of acidifying in juice. The prolongated format predominated in the fruits of the five genotypes at the three analyzed periods
