title: The Effectiveness of Coronary Artery Bypass Grafting in Patients with Left Ventricular Dysfunction

description: ABSTRACT Introduction: Coronary artery bypass grafting (CABG) in patients with left ventricular dysfunction (LVD) remains a surgical challenge and is still controversial. The aim of this study was to evaluate the effectiveness of CABG in patients with LVD. Methods: This retrospective study included a total of 160 consecutive patients (133 males, 27 females, mean age 62.1±10.12 years [range 37 to 86 years]) who had a left ventricular ejection fraction (LVEF) ≤ 45% determined by echocardiography and underwent elective isolated CABG between September 2013 and December 2018. Preoperative echocardiographic data, such as ejection fraction, left ventricular (LV) end-systolic diameter, and LV end-diastolic diameter, were collected and evaluated. Preoperatively, 85 (53.13%) patients were in New York Heart Association functional class III or IV and the mean LVEF was 38.65±5.72% (range 20 to 45). Results: The overall hospital mortality was 5% (eight patients). Late follow-up was obtained in 152 (90%) cases (median follow-up time was 56,5 [3-87] months postoperatively). During follow-up, mortality developed in 11.3% (16 patients). Mean LVEF increased significantly from 38.78±5.59% before surgery to 43.29±8.46% after surgery (P&lt;0.01). Mean late survival, freedom from coronary reintervention, and congestive heart failure rates were 86.3±3.3%, 88.7±3.9%, and 89.4±3.1%, respectively. Conclusion: In patients with LVD, CABG can be performed with low postoperative morbidity and mortality rates. Patients with LVD could benefit from coronary bypass surgery regarding postoperative LV systolic function and higher quality of life.

title: Exchange of germoplasm and genetic diversity to enrichment the Desmanthus genebank

description: ABSTRACT The genus Desmanthus presents wide ecogeographical distribution and complex taxonomy. Desmanthus pernambucanus (L.) Thellung, popularly known in Brazil as Jureminha, is a leguminous species native to the Northeast region of Brazil, which stands out by its high protein content, resistance to droughts, and by presenting no toxicity to animals. The objective of this work was to evaluate the genetic diversity of 15 progenies from the Commonwealth Scientific and Industrial Research Organization (CSIRO; Australia), through germplasm exchange for enrichment of the Desmanthus genebank of Embrapa Tabuleiros Costeiros, in Nossa Senhora das Dores, SE, Brazil. Fifteen ISSR markers were used, from which 8 were selected. The progenies identified as 242, 245, 246, 255, and 268 were the most genetically distant, and the most recommended to be introduced to the genebank.

title: Early screening for cold tolerance in sugarcane breeding

description: Abstract The objective of this work was to evaluate the efficiency of early screening in the selection of sugarcane (Saccharum spp.) families for cold tolerance in a controlled environment. Fourteen sugarcane families were evaluated for leaf damage and chlorophyll content, in a controlled environment and in the field, after cold stress. The variance components and genotypic values of the families were estimated via REML/BLUP, as well as the genetic correlations between variables and environments. The heritabilities in the narrow sense and for family averages showed values above 0.23 and 0.76, respectively, and a genetic coefficient of variation above 13%, which confirmis the existence of variability and enables selection in both environments. The genetic correlations ranged from 0.59 to 0.88 and were significant for all combinations of variables and environments. The average coincidence index for the families between environments was 60% for the selected group and 85% for the unselected group. The early screening in the first stages of selection is efficient in breeding for cold tolerance in sugarcane families.

title: Plot size and number of repetitions in forage wheat

description: ABSTRACT Forage wheat (Triticum aestivum L.) is an annual crop, alternative for use as a ground cover crop in the winter period, in production systems in southern Brazil. Given its magnitude, research with field experiments is carried out and plot size definition is of great importance in the experimental design. The objectives of this study were to estimate the plot size and number of repetitions to evaluate the fresh matter of forage wheat and to investigate the variability of plot size among agricultural years, sowing dates and cultivars. Thirty-six uniformity trials were conducted (two agricultural years × three sowing dates × two cultivars × three repetitions). Plot size was determined by the method of maximum curvature of the coefficient of variation model. The number of repetitions was determined for experiments in completely randomized and randomized block designs in scenarios formed by the combinations of i treatments (i=3, 4, …, 50) and d least significant differences among treatment means to be detected as significant by the Tukey test, at 5% of significance, expressed as a percentage of the overall mean of the experiment (d=5%, 10%, …, 30%). The plot size to evaluate the fresh matter of forage wheat is 4.05 m2. Seven repetitions are sufficient to identify the fresh matter in completely randomized designs and randomized block designs with up to 50 treatments, making it possible to obtain least significant difference lower than or equal to 20% of the mean of the experiment.

title: Morphological responses of maize hybrids under competition with hairy beggarticks

description: ABSTRACT The study of competitive interactions between crops and weeds can be an important tool in integrated weed management. The objective of this work was to evaluate the competitive ability of maize hybrids in the presence of hairy beggarticks, testing different proportions of plants in the associations. For maize hybrids (Dekalb 230 PRO3, Pioneer 30F53 VYH, Brevant 2B433 PW, and Syngenta 505 VIP3) and for hairy beggarticks, the final density was 20 individuals pot-1, which was determined in preliminary experiments. Experiments were carried out on a substitutive series, on different combinations of the species, varying the relative proportions (100:0, 75:25, 50:50, 25:75, and 0:100%). The analysis of species competitiveness was performed using diagrams applied to the substitutive experiments and relative competitiveness indices. The maize hybrids showed less loss when reducing the morphological variables of the hairy beggarticks and demonstrated superiority in competitive ability in relation to the weed. Competition occurred between maize hybrids in the presence of hairy beggarticks, being negatively affected, regardless of the proportion of plants, causing reductions in plant height, stem diameter, leaf area, and dry mass. An average reduction of 10% and 86% of the MS of maize hybrids and weed was observed, respectively, when comparing the absence of competition with any associated densities, intraspecific competition being more harmful than interspecific. Maize hybrids and hairy beggarticks compete for the same environmental resources, with the crop being more competitive than the competitor.

title: Genetic diversity pattern of Passiflora spp. in Boyacá, Colombia

description: Abstract The objective of this work was to characterize the genetic diversity, using ISSR markers, of 70 genotypes of five species of Passiflora spp. in Boyacá, Colombia. For molecular characterization, samples of young leaves were collected from 11 municipalities of the Boyacá department. Genetic similarity was used to cluster the genotypes by the UPGMA method, and genetic structure was evaluated by the Bayesian model. Eight ISSR primers produced 138 loci. The formed cluster consists of two populations, with most individuals of the same species but from different geographic origins. The percentage of polymorphic loci is higher than 80%. The average value of heterozygosity is between 0.29 and 0.36 for population I and II, respectively, and the values of polymorphic information content are low. A moderate genetic differentiation (0.16) and high gene flow (3.35) are observed.

title: Biochemical differences in the initial growth of sugarcane varieties cultivated under different potassium doses and water conditions

description: ABSTRACT Sugarcane varieties have distinct biochemical and productive capacities, which are accentuated under water and nutrient stress conditions. Water stress promotes biochemical changes in plants, such as the overproduction of reactive oxygen species (ROS) that, depending on the concentration, degrade photosynthetic pigments. Current research indicates that K+ plays an important role in increasing yield and tolerance to water stress. This study evaluated the effect of different K+ levels on the initial growth of two sugarcane varieties under two water conditions. The experiment was conducted in a greenhouse using randomized blocks, with four replications, five K+ doses (0; 0.5; 1; 2 and 6 mmol L-1), two sugarcane varieties (RB92579 and RB992506), and two water conditions (hydrated plants and water stress). Data were analyzed in a 5×2×2 factorial scheme. Leaf carbohydrates, photosynthetic pigments, antioxidant enzyme activity (catalase, superoxide dismutase and ascorbate peroxidase) and dry matter production were assessed. K+ doses promoted an increase in plant dry mass. The RB992506 variety had lower APX activity and higher levels of photosynthetic pigments, carbohydrates and dry matter than its RB92579 counterpart. Water conditions and interactions between factors had no effect on the variables studied. RB992506 is a promising variety and more tolerant to water stress due to its superior biochemical and productive traits when compared to RB92579.

title: Computed tomography fluoroscopy-guided percutaneous biopsy of pulmonary nodules ≤ 10 mm: retrospective analysis of procedures performed during the COVID-19 pandemic

description: Abstract Objective: To evaluate the diagnostic performance of computed tomography (CT) fluoroscopy-guided percutaneous transthoracic needle biopsy (PTNB) in pulmonary nodules ≤ 10 mm during the coronavirus disease 2019 pandemic. Materials and Methods: Between January 1, 2020 and April 30, 2022, a total of 359 CT fluoroscopy-guided PTNBs were performed at an interventional radiology center. Lung lesions measured between 2 mm and 108 mm. Of the 359 PTNBs, 27 (7.5%) were performed with an 18G core needle on nodules ≤ 10 mm in diameter. Results: Among the 27 biopsies performed on nodules ≤ 10 mm, the lesions measured &lt; 5 mm in four and 5-10 mm in 23. The sensitivity and overall diagnostic accuracy of PTNB were 100% and 92.3%, respectively. The mean dose of ionizing radiation during PTNB was 581.33 mGy*cm (range, 303-1,129 mGy*cm), and the mean biopsy procedure time was 6.6 min (range, 2-12 min). There were no major postprocedural complications. Conclusion: CT fluoroscopy-guided PTNB appears to provide a high diagnostic yield with low complication rates.

title: Total Thoracoscopic Surgery for Late Mitral Paravalvular Leakage Repair in A Beating Heart

description: Abstract Paravalvular leakage (PVL) after mitral valve replacement is a troublesome complication that may lead to severe symptoms and reoperation. Previous case reports on total thoracoscopic cardiac surgery without aortic cross-clamping for repairing late PVL are rare. We describe a 64-year-old man who had undergone aortic and mitral valve replacement via median sternotomy eight years earlier, and who recently developed cardiac failure due to severe tricuspid regurgitation (TR) and PVL in the posterior mitral annulus. During total thoracoscopic surgery with using the beating heart technique, direct closure of the PVL was achieved via pledgeted mattress sutures, and tricuspid valvuloplasty was routinely performed to treat TR. This case indicated that total thoracoscopic surgery on a beating heart may be an excellent option for treating PVL concomitant with TR.
