title: Cardiac Surgery-associated Acute Kidney Injury in Patients with Preserved Baseline Renal Function

description: ABSTRACT Introduction: Cardiac surgery-associated acute kidney injury (CSA-AKI) is a powerful predictor of perioperative outcomes. We evaluated the burden of CSA-AKI in patients with preserved baseline renal function. Methods: The data of 2,162 adult patients who underwent cardiac surgery from January 2005 to December 2020 were analyzed. Logistic regression models were used to determine predictors of CSA-AKI and their associations with hospital mortality up to 30 days. Results: The prevalence of acute kidney injury was 43.0%, and 2.0% of patients required renal replacement therapy. Hospital mortality rate was 5.6% (non-acute kidney injury = 2.0% vs. CSA-AKI = 10.4%, P&lt;0.001), and any degree of CSA-AKI was associated with a significant increase in death rates (stage 1 = 4.3%, stage 2 = 23.9%, stage 3 = 59.7%). Multivariable logistic regression analysis identified age, obesity, left ventricular dysfunction, previous cardiac surgery, and cardiopulmonary bypass duration as predictors of CSA-AKI. Moreover, CSA-AKI was confirmed as independent predictor of hospital mortality for stage 1 (odds ratio, 2.02; 95% confidence interval, 1.16 to 3.51; P=0.013), stage 2 (odds ratio, 9.18; 95% confidence interval, 4.54 to 18.58; P&lt;0.001), and stage 3 (odds ratio, 37.72; 95% confidence interval, 18.87 to 75.40; P&lt;0.001) patients. Conclusion: Age, obesity, left ventricular dysfunction, previous cardiac surgery, and cardiopulmonary bypass duration are independent predictors of CSA-AKI in patients with preserved baseline renal function. The development of CSA-AKI is significantly associated with worse outcomes, and there is a dose-response relationship between acute kidney injury stages and hospital mortality.

title: Evaluation of natural ventilation strategies in school classrooms in a humid subtropical climate

description: Abstract Classrooms are long-stay environments, in which thermal comfort is fundamental to the teaching and learning process. In the context of Covid-19, higher rates of natural ventilation are required, which can affect thermal comfort. This research aimed to investigate 16 natural ventilation strategies in elementary school classrooms regarding energy efficiency, thermal comfort and quality of natural ventilation, in a humid subtropical climate, represented by the city of Santa Maria, RS, considering recommendations from the Federal Government and computer simulations with Ansys CFX ® and EnergyPlus. The following items were analysed: hours spent in thermal comfort, discomfort degree-hours, indoor air velocity, air renewal rates and air humidity. Strategies using cross ventilation and solar chimney, or north-south unilateral ventilation connected to open circulation met the criteria for air renewal, albeit with a 20% or more hours of discomfort due to cold. It was observed that sufficient natural ventilation causes discomfort due to excessive cold. The contribution of this project is to suggest more adequate natural ventilation strategies for classrooms located in humid subtropical climates, demonstrating that they can contribute to improve the quality of natural ventilation compared to conventional solutions.

title: Women, prisons, and freedom: experiences of former female inmates from the prison system in Rio Grande do Sul, Brazil

description: Abstract This article analyzes vulnerabilities and prospects of restructuring the lives of women who experienced maternity in prison. This qualitative study was performed with a thematic analysis of the reports of women released from the prison system who experienced pregnancy and delivery in a female penitentiary in a Southern Brazilian capital. Three thematic categories were identified: “Between rupture and freedom”, a category focused on the description of moments before the borderline date for the child’s stay with the mother in prison, which produces great expectations due to the possibility of women managing to get out of prison along with their child; “Freedom is right there”, which narrates leaving prison and the first social contacts outside this environment; and “Inmate in daily life”, which addresses the difficulties resulting from social exclusion that women were already facing before imprisonment, that is, having the minimum conditions to keep away from the crime dynamics. Leaving the prison system does not necessarily mean freedom. The “identity crossroads” keep following women and their children even after leaving prison. Therefore, vulnerability manifests itself in the same way or more cruelly than before.

title: REACTIONS OF LIMA BEAN (Phaseolus lunatus L.) ACCESSIONS TO Colletotrichum truncatum

description: ABSTRACT Lima bean (Phaseolus lunatus) can be considered as an alternative income and food supply to farmers of the Brazilian Northeast. This crop has faced serious sanitary problems. Among the most important diseases that attack this crop, the anthracnose caused by Colletotrichum truncatum requires greater attention. This study aimed to determine the resistance of lima bean accessions to the isolates of C. truncatum. Detached leaves were used from ten lima bean accessions, originated from production fields in Paraíba State - Brazil. They were artificially inoculated with ten isolates of C. truncatum. The isolates were grown on bean-dextroseagar medium under temperature 27 ± 2 °C and a photoperiod of 12 hours, for fourteen days. The evaluations of the accessions’ resistance to the isolates were performed at 5, 7, 9, 11 and 13 days after inoculation (DAI), adopting a scale of notes, and the results were transformed in the area under the disease progress curve. The research was carried out in completely randomized design, in a 10x10 factorial arrangement (accessions x isolates) with 12 replications. The first symptoms of anthracnose on the detached leaves appeared from the third day after inoculation. The accessions were grouped from highly to moderately resistant or susceptive. The aggressiveness among C. truncatum isolates varied depending on the genetic variability of the lima bean accessions used. Accessions with significant resistance levels to anthracnose can be used as resistance sources in future breeding programs.

title: CLASSIFICATION OF Phaseolus lunatus L. USING IMAGE ANALYSIS AND MACHINE LEARNING MODELS

description: ABSTRACT Image analysis combined with machine learning models can be an excellent tool for classification of fava (Phaseolus lunatus L.) genotypes and is a low-cost system. Fava is grown by family farmers, mainly, in the Northeast and South regions of Brazil, presenting economic and social importance. Evaluations to gather information on qualitative and quantitative characters of seeds enable the description and distinction of genotypes, allowing the evaluation of variability of plant species, which is essential in breeding programs. The use of image analysis is a fast and economic tool for obtaining large quantity of information. Machine learning techniques have been developed and implemented in the agricultural sector due to technological advances and increasing use of artificial intelligence, which enables the automatization of several processes. In this context, the objective of this work was to evaluate different machine learning models to classify fava genotypes, using data obtained through image analysis. Images of fava seeds were captured using a table scanner (HP Scanjet 2004), set to true color mode, arranged upside down inside of an aluminum box fully closed during the capture of the images for an adequate illumination and prevention of environmental noises. The K-Nearest Neighbor, Naive Bayes, Linear Discriminant Analysis, Support Vector Machine, Gradient Boosting, Bootstrap Aggregating, Classification and Regression Trees, Random Forest, and C50 models were used for the study. Linear Discriminant Analysis was the model that presented the highest efficiency for classifying the genotypes, with an accuracy of 90%.

title: Analysis of crystalline nanocellulose dispersion process forthe production of cementitious composites

description: Abstract This paper aims to investigate the dispersion process of aqueous suspensions with crystalline nanocellulose (NCC) for the production of cementitious composites reinforced with crystalline microcellulose (MCC) and polypropylene fibers (FPP). Initially, aqueous solutions with nanocellulose with different levels of surfactant were characterized in terms of dispersion quality through dynamic light scattering, zeta potential and UV-Vis spectroscopy, aiming to determine the ideal surfactant content. Subsequently, the aqueous suspensions were added to the cement/sand mixture to prepare the composites. The properties in the fresh and hardened states were investigated for each addition level. The optimal content of Pluronic to disperse the nanocellulose was 40% in relation to its mass. The results showed a reduction in the workability of the samples. In terms of mechanical performance, the composites of recipe 1 (0.3% FPP, 0.5% MCC and 0.3% NCC) showed increases of around 17% in compressive resistance at 56 days, 18% in elasticity modulus and around 7% in tensile strength in flexion at 28 days.

title: Circumflex Coronary Artery Fistula Draining into Coronary Sinus

description: ABSTRACT Coronary artery fistula draining into the coronary sinus is a rare vascular malformation, and its diagnosis and clinical manifestations usually occur late. We describe the case of a 72-year-old female patient with dyspnea on exertion (New York Heart Association Class III) associated with palpitations. The transthoracic echocardiogram showed significant tricuspid insufficiency. Cardiac catheterization showed aneurysm of the circumflex coronary artery and fistula of this artery draining into the coronary sinus. The patient underwent fistula ligation and tricuspid valve repair, with excellent surgical results.

title: CANONICAL CORRELATIONS BETWEEN MORPHOLOGICAL AND PRODUCTION TRAITS IN SPECIAL TYPES OF RICE

description: ABSTRACT The rich genetic diversity and wide adaptation of rice (Oryza sativa L.) to different environments provide fundamental resources for its conservation and improvement. The analysis of canonical correlations can be used to increase the efficiency of selecting superior genotypes, as several traits are evaluated simultaneously. Thus, this study aimed to compare morphoagronomic traits and estimate the magnitude of the association and interdependence between two groups of traits in genotypes of special types of rice. The experiment was carried out between November 2020 and April 2021 at the Department of Plant Science of the Federal Rural University of Rio de Janeiro (UFRRJ), Seropédica - RJ. The experimental design consisted of randomized blocks, with four replications. Seventeen genotypes were evaluated, five of them consisting of white rice and eleven special types of rice. Two groups of variables were used to determine the canonical correlations, with group I composed of four morphological traits and group II composed of four yield components. Significant differences (P&lt;0.01) were observed between genotypes for the eight evaluated traits. The first, second, and third pairs showed significant canonical correlations at a 5% probability, demonstrating that these groups are not independent. The selection of superior genotypes for production can be based on choosing plants with higher flag leaf thickness, higher height, and lower flag leaf angle.
