title: Invasive Versus Conservative Management of NSTEMI Patients Aged ≥ 75 Years

description: Abstract Background The efficiency of invasive management in older patients (≥75 years) with non-ST-segment elevation myocardial infarction (NSTEMI) remains ambiguous. Objectives To assess the efficiency of invasive management in older patients with NSTEMI based on meta-analysis and trial sequential analysis (TSA). Methods Relevant randomized controlled trials (RCT) and observational studies were included. The primary outcomes were all-cause death, myocardial infarction, stroke, and major bleeding. Pooled odd ratio (OR) and 95% confidence interval (CI) were calculated. P &lt;0.05 was considered statistically significant. Results Five RCTs and 22 observational studies with 1017374 patients were included. Based on RCT and TSA results, invasive management was associated with lower risks of myocardial infarction (OR: 0.51; 95% CI: 0.40-0.65; I2=0%), major adverse cardiovascular events (MACE; OR: 0.61; 95% CI: 0.49-0.77; I2=27.0%), and revascularization (OR: 0.29; 95% CI: 0.15-0.55; I2=5.3%) compared with conservative management. Pooling results from RCTs and observational studies with multivariable adjustment showed consistently lower risks of all-cause death (OR: 0.57; 95% CI: 0.50-0.64; I2=86.4%), myocardial infarction (OR: 0.63; 95% CI: 0.56-0.71; I2=0%), stroke (OR: 0.59; 95% CI: 0.51-0.69; I2=0%), and MACE (OR: 0.64; 95% CI: 0.54-0.76; I2=43.4%). The better prognosis associated with invasive management was also observed in real-world scenarios. However, for patients aged ≥85 years, invasive management may increase the risk of major bleeding (OR: 2.68; 95% CI: 1.12-6.42; I2=0%). Conclusions Invasive management was associated with lower risks of myocardial infarction, MACE, and revascularization in older patients with NSTEMI, yet it may increase the risk of major bleeding in patients aged ≥85 years.

title: Production of highly soluble foliar fertilizer in a spouted bed dryer

description: ABSTRACT The drying process can be useful to change the particulate structure, improving the powder solubility. In this study, we investigated the drying of foliar fertilizer in a spouted bed using polyethylene pellets as inert particles to improve its solubility. A 23 factorial experimental design was used to evaluate how the powder yield and moisture were affected by the feeding time, intermittency time, and feed atomizer position. The spouting instability caused powder retention on the bed wall, which decreased the powder recovery efficiency by 2.3-26.6%. Although the powder recovery efficiency was low, the solubility time was reduced by 5.9 times, probably due to particle agglomeration, which increased the amorphous phase of the fertilizer. Design alterations, suggested by the CFD data, can increase spouted bed stability and facilitate centralized spouting. Based on this, the spouted bed drying technique was applied, and it effectively increased the solubility of commercial fertilizer, thus, incorporating more desirable characteristics for field applications.

title: Populism or budgetary endogeneity? Discretionary fiscal policy in Argentina

description: ABSTRACT This paper uses the Fischer equation and Olivera-Tanzi effect to insulate the inflationary endogeneity existing in Argentine public deficit. The outcome is a fiscal policy discretionary measure known as zero inflation budget. Through this measure we examine if the deficit reflects countercyclical policies or populist consumption targets.

title: Tropical Trump, or a very Brazilian tale? Social class resentment as a moderating factor between anti-PT sentiment and the vote for Jair Bolsonaro in 2018

description: Prior analyses of authoritarian populism have linked it to hypotheses referring to cultural backlash and negative partisanship, suggesting that conservative values and hatred of opposing parties fuel the desire for strong leadership. This article adds to the previous literature by testing the influence of social class resentment on Bolsonaro coming to power in Brazil. Based on the AmericasBarometer 2018/19 survey, the analysis highlights the central role of the rejection of the Partido dos Trabalhadores (Workers’ Party) in explaining the propensity to vote for the far-right candidate, and to a lesser extent, the influence of authoritarian values in this case study. Our findings lend some support to the hypothesis of social class resentment as well. Social class resentment was found to significantly moderate the relationship between anti-PT sentiment and voting behavior, which sheds light on Bolsonaro’s ability to capture resentful voters who were disposed to subordinate social redistribution to the defense of previously acquired privileges.

title: Synthesis of Polycardanol Using BF3.O(C2H5)2 as Initiator: Influence of Polymerization Conditions on Reaction Products

description: Cardanol acts to stabilize asphaltene particles in crude oil, but its derivative polycardanol, synthesized with BF3.O(C2H5)2 as initiator, exhibits divergent behavior, acting as both asphaltenes stabilizer and flocculant. This behavior could be related to structural differences in polycardanol samples. Therefore, in this work, we study the influence of some polymerization conditions (monomer purity, initiator concentration, and reaction time) on the structures and molar masses of the reaction products, and the reaction conversion. The materials were characterized by size exclusion chromatography and hydrogen and carbon nuclear magnetic resonance. When reacting with distilled cardanol, the conversion, the molar mass, and the homogeneity of structures increased as increasing initiator concentration in the range tested (1-3% m/m). For both monomers (different purity degrees), when using a lower initiator concentration (1% m/m), the product contained a larger amount of unreacted monomer and different structures were obtained due to the occurrence of rearrangements. The presence of triolefinic molecules in the monomer provoked crosslinked structures for higher initiator concentration (2-3% m/m). This study elucidated the differences among the reaction products of polycardanol.

title: Droplet spectrum characteristics and drift potential of different droplet classes and spray volumes application of atrazine with nicosulfuron

description: ABSTRACT: In this research, the Volumetric Median Diameters (VMDs), Relative Span (RS), percentage of droplets with a diameter smaller than 100 µm (V100), and percentage ofdrift (% drift) of four droplet classes (Fine, Medium, Coarse, and Very Coarse) were analyzedin two spray volumes (77 L.ha-1and 144 L.ha-1) employinga tank-mix of atrazine and nicosulfuron herbicides (2500 + 15 gaiha-1), usingParticle/Droplet Imaging Analyze (PDIA) and wind tunnel techniques. The experiments were performed under Completely Randomized Design, in a 4 × 2 factorial scheme (droplet classes × sprayvolumes). Data underwent analysis of variance and Tukey’s test at 5%, and the correlation between variables was computedconsidering Pearson’s coefficient at 1% and 5%. The VMD of all droplet classes was considerably distinct in the two spray volumes. In both application spray volumes, the minimum VMD for the Coarsedropletclass classification was not attained. The highest means of RS were detectedin the spray volume of 77 L.ha-1. All treatments demonstratedsignificant differences in the analysis of V100 and % drift, with the highest means observed in the Fine droplet (144 L.ha-1) and Medium (77 L.ha-1). A negative correlation existed between VMD × V100 and VMD × % drift and a positive correlation between V100 × % drift in the two spray volumes. RS was negatively correlated with VMD and positively with V100 and % drift, in the spray volume of 77 L.ha-1. In the spray volume of 144 L.ha-1, the correlation between RSand VMD, V100, and % drift was insignificant.

title: Specialized Rehabilitation Centers (CER) in the SUS and the impact of the covid-19 pandemic

description: ABSTRACT OBJECTIVE To analyze the impact of the covid-19 pandemic on the functioning of Specialized Rehabilitation Centers (CER) in the SUS. METHODS An analysis of the variation in outpatient production of the CER was carried out based on data from the Outpatient Information System of the Unified Health System (SIA-SUS) from March 2019 to December 2021. Such results were compared with CER managers’ perceptions about the impacts of the pandemic on the units, measured by a web survey applied between November 2020 and February 2021. Monthly averages of 247 procedures were calculated, organized into 18 groups, for three periods – year before the pandemic (YBP) and first (YP1) and second (YP2) years of the pandemic. Through the online form, information was collected on: operation and organization of services; post-covid-19 rehabilitation; actions to support the needs of users and professionals; strategies and challenges experienced. RESULTS There was a 33.3% reduction in the total number of procedures in YP1 compared to YBP. There were no reductions in procedures performed by nurses and for ostomates. There was greater impairment for group activities, visual therapies and home visits. In YP2, there was a recovery of averages in relation to YBP in 11 groups of procedures, with an increase of 104.1% in Cardiorespiratory Physiotherapy. In the answers to the online form, 91.7% of the managers indicate structural and/or organizational changes in the CER, such as: creation of prioritization criteria for assistance; introduction of telerehabilitation; changes in the work process and; provision of professional training. Half of the CER already treated people with covid-19 sequelae, but not all of them had been trained to do so. Limitations in participation and social support for PWD were identified. CONCLUSIONS There was a severe impact of the covid-19 pandemic on the CER. Added to the damming up of previous demands are those of post-covid-19 users, configuring a challenging picture. It is necessary to strengthen the Care Network for Persons with Disabilities, with expansion and greater integration of services and a more inclusive organization to overcome these challenges.

title: The Constitution, interest and the economy

description: Abstract The promulgation of the Brazilian Constitution of l988, reinstated the so-called Usury Law. According to this old regulament, which was never revoked but that was made ineffective due to the extremely high rates of inflation that we have been experiencing since a long time ago, the rate of interest, in nominal terms, cannot exceed 12% yearly. Aiming to innovate, while at the same time ignoring the ever-present law of supply and demand, the 1988 Constitution established that ceiling in real terms. The paper focuses not only on the difficulties of measuring the effective rate of interest that is charged on bank loans, but also on the almost impossible task of measuring it in real terms. The unavoidable conclusion is that this new version of the Usury Law will be also rendered ineffective in practice.

title: Multi-Analytical Characterization of Rupestrian Precolonial Paintings of Inhuma, Piauí, Brazil

description: The chemical-mineralogical characterization of rupestrian paintings in red, white, black and yellow colors, which decorate the rocky walls from the archaeological sites of Ema and Furna dos Índios (Inhuma, Piauí, Brazil) was performed. The chemical analyses were performed in situ by the non-invasive analytical technique X-ray fluorescence spectrometry (XRF) as well as in laboratory using a non-destructive approach, without previous sample preparation, and Raman microscopy, and scanning electron microscopy coupled with energy dispersive spectroscopy (SEM-EDS) techniques. The results, when together, allowed unequivocal identification of the main substances responsible for the color pigments, namely, hematite (red pigment), gypsum (white pigment), amorphous carbon from charcoal (black pigment) and goethite (yellow pigment).

title: Computation-Guided Support to Experiments by the Exploration of Reaction Mechanisms: Organic Synthesis, Natural Products and Environmental Issues

description: Humankind has experienced a remarkable development since it began to design and optimize chemical reactions to achieve valuable compounds. The key to accomplish these tasks is the proper understanding of how chemical transformations occur at a molecular level, that is, their reaction mechanisms. Based on a suitable mechanistic proposal, experimentalists choose a given chemical protocol to optimize experimental conditions, design new synthetic routes, and circumvent competing reactions. In this context, computational chemistry has become a valuable ally for mechanistic elucidation. We present herein a review of complementary collaborations between experimentalists and theoretical chemists to rationalize processes at the molecular level, focusing mainly on the fields of organic synthesis, natural product chemistry, and systems with environmental interest. Throughout this review, we highlight the ability of computational evaluations to provide answers to questions raised from experiments in a clear and direct way, indicating to experimentalists alternative paths to help them solve their problems.
