title: One-year clinical evaluation of class II bulk-fill restorations in primary molars: a randomized clinical trial

description: Abstract This double-blind, randomized clinical trial aimed to compare the clinical performance and clinical time to restore occluso-proximal cavities in primary molars withbulk-fillresin and conventional resin. A total of 140 class II restorations in primary molars of 65 participants (mean age of 6.7 + 1.5) were placed in two random groups:bulk-filland conventional resin. The restorations were evaluated using FDI criteria at the baseline, 6-month, and one year by a single calibrated examiner, and the clinical restorative time was measured with a digital timer. The success and survival of the restorations were evaluated with Kaplan-Meier graphs. The log-rank test compared the curves. Differences in restorative clinical time were compared using the Mann-Whitney U test. The level of significance was 5%. After one year, 115 restorations were evaluated. The success probability was 88.7% for Filtek Z350 XT and 85.9% for FiltekTM Bulk-fill, and for the survival probability, Filtek Z350 XT presented 90%, and FiltekTM Bulk-fill presented 93.7%. No significant difference was found between the success and survival curves (p=0.62), (p=0.51). The main reason for failure was marginal adaptation.Bulk-fillresinrequired 30% less time than the conventional resin (p&lt;0.001).Bulk-fillresin presented similar clinical performance to the conventional resin and required less restorative clinical time. It is an option to restore class II lesions of primary molars.

title: Cartographic Accuracy Standard (CAS) of the digital terrain model of the digital and continuous cartographic base of the state of Amapá: case study in the city of Macapá

description: Abstract: The Cartographic Accuracy Standard (CAS) is a quality parameter used by the Brazilian standard to estimate the positional quality of cartographic products in their degree of precision, also including altimetry. The Digital and Continuous Cartographic Base of Amapá - BCDCA has a large amount of freely available spatial information, for the study of its territory within the state of Amapá. This project, a partnership between the Government of the State of Amapá and the Directorate of Geographical Services of the Brazilian Army (DSG), obtained a large amount of SAR data by interferometry. Among the resulting products, the Digital Terrain Model - DTM has a wide range of applications: watershed analysis, infrastructure program, diagnosis of environmental risks and so many others. Therefore, the present work aims to evaluate the altimetric data (DTM) provided by the BCDCA through 2172 orthometric points calculated from the Brazilian Network for Continuous Monitoring - RBMC measured in the field in the city of Macapá, capital of the State of Amapá. For the level curves, the results presented class A for the 1: 10 000 scale, at an equidistance of 5 m, showing that the DTM product is highly reliable for urban applications.

title: Cardiomyopathy Induced by Artificial Cardiac Pacing: To Whom, When, Why, and How? Insights on Heart Failure Development

description: ABSTRACT Coordinated and harmonic (synchronous) ventricular electrical activation is essential for better left ventricular systolic function. Intraventricular conduction abnormalities, such as left bundle branch block due to artificial cardiac pacing, lead to electromechanical “dyssynchronopathy” with deleterious structural and clinical consequences. The aim of this review was to describe and improve the understanding of all the processes connecting the several mechanisms involved in the development of artificially induced ventricular dyssynchrony by cardiac pacing, most known as pacing-induced cardiomyopathy (PiCM). The chronic effect of abnormal impulse conduction and nonphysiological ectopic activation by artificial cardiac pacing is suspected to affect metabolism and myocardial perfusion, triggering regional differences in the activation/contraction processes that cause electrical and structural remodeling due to damage, inflammation, and fibrosis of the cardiac tissue. The effect of artificial cardiac pacing on ventricular function and structure can be multifactorial, and biological factors underlying PiCM could affect the time and probability of developing the condition. PiCM has not been included in the traditional classification of cardiomyopathies, which can hinder detection. This article reviews the available evidence for pacing-induced cardiovascular disease, the current understanding of its pathophysiology, and reinforces the adverse effects of right ventricular pacing, especially right ventricular pacing burden (commonly measured in percentage) and its repercussion on ventricular contraction (reflected by the impact on left ventricular systolic function). These effects might be the main defining criteria and determining mechanisms of the pathophysiology and the clinical repercussion seen on patients.

title: THE FOREIGN LANGUAGE IN HIGHER EDUCATION: AN ANALYSIS OF ITS OFFER IN BRAZILIAN UNIVERSITIES

description: ABSTRACT: This study focuses on offering Foreign Language (FL) disciplines in national Higher Education given the demands of the academic and professional spheres through the parameters of the globalized society and its influence on the university internationalization process. Therefore, a brief history of higher education institutions in the country is presented, up to the configuration of recent institutional models, focusing on a new law of 1996, LDB (Guidelines and Bases of the Brazilian Education), which enabled the preparation of the National Curriculum Guidelines (DCN) and the reformulation of the curricula at all levels of education. This way, following the need for mastery of a FL, especially the English Language, considered as an academic lingua franca, a survey was carried out for the provision of FL in undergraduate courses based on opinions and decrees that they have guided their curricula over the last two decades, publicly available on the Ministry of Education and Sports website. By analyzing the files, mentions to the domain of FL were perceived, sometimes defined as FL and the Spanish language. Its offer is mainly related to developing communicative competence and reading ability. Thus, we observed that the FL has the role of allowing access, participation, and dissemination of academic research and extension activities globally, in addition to being related to the performance of the professional in training given current demands.

title: Treatment of swine wastewater in a biological system for disposal in a sandy soil

description: ABSTRACT This work aimed to evaluate the efficiency of a system composed of a UASB reactor followed by post-treatment with an aerobic granular sludge reactor (AGS) in the treatment of swine wastewater (SW) for disposal in sandy soil. The characteristics of the treated effluent and the soil from a disposal site were evaluated, as well as the parameters of mobility of contaminants such as dispersion coefficient (D), dispersivity (λ), delay factor (R), and Péclet number (Pe) were determined. Treated SW was percolated in a permanent flow regime in columns of saturated soil. Elution curves (breakthrough curves) were generated, obtaining the transport parameters by adjusting the solute transport equation in the soil. The soil used was characterized as a quartzene soil with a sandy texture. It was observed that, although the treatment presents high removal efficiencies for COD, BOD, TSS, nitrogen, and phosphorus, the treated SW still did not meet some parameters for surface water discharge or soil disposal based in current legislation. Except for phosphate and potassium, ions showed a tendency to move in the soil and to contaminate the groundwater.

title: Efficiency of trap nests in attracting stingless bees in the central Brazilian Amazon

description: ABSTRACT Obtaining colonies of stingless bees in the wild for the formation or expansion of meliponaries and other purposes is permitted by law in Brazil using bait containers or trap nests, and other non-destructive methods. We tested the efficiency of trap nests made from plastic bottles for attraction and nesting of stingless bees in the central Brazilian Amazon. We used 2-L and 5-L bottles and three types of attractants (cerumen and geopropolis from Melipona seminigra, M. interrupta and a mix of the two). We used 216 trap nests distributed in three experimental areas during 13 months. Visitation by six species of stingless bees in 58 (26.9%) trap nests, and nesting by three species in 12 (5.6%) trap nests in two areas near meliponaries was recorded. There was no significant difference between trap-nest size, nor among attractants for visitation or nesting, suggesting that the availability of cavities or hollows is more important than odor for nesting. Monthly pooled visitation and nesting events were not correlated with monthly rainfall. Based on our results, we can conclude that, despite the low capture rate, the acquisition of swarms through nest traps is a viable alternative to obtain new colonies of stingless bees for meliponaries.

title: Complications of tracheostomy in children: a systematic review

description: Abstract Introduction: Tracheostomy is a procedure that can be associated with several well-described complications in the literature, which can be divided into transoperative, early postoperative and late postoperative. When performed in children, these risks are more common than in adults. Objective: To perform a systematic review of complications, including deaths, in tracheostomized pediatric patients. Methods: A search was carried out for articles in the Latin American and Caribbean Health Sciences Literature and PubMed databases. Cohort studies and series reports were selected, in addition to systematic reviews, published between January 1978 and June 2020, with patients up to 18 years old, and written in English, Spanish or Portuguese. Results: 1560 articles were found, of which 49 were included in this review. The average complication rate was 40%, which showed an association with age, birth weight, prematurity, comorbidities, and emergency procedures. The most common complications were cutaneous lesions and granulomas. Mortality related to the procedure reached up to 6% in children and was mainly related to cannula obstruction or accidental decannulation. Conclusion: Pediatric tracheostomy is associated with several complications. The tracheostomy-related mortality rate is low, but the overall mortality of tracheostomized patients is not negligible.

title: Factors associated with postoperative signs and symptoms in teeth with periapical lesion: a longitudinal study

description: Abstract This study aimed to evaluate the association of the variables age, gender, arch position, tooth length, root canal amplitude, and periapical lesion size with the occurrence of postoperative signs and symptoms (pain, tenderness, and edema) and the use of postoperative analgesics following root canal treatment with foraminal enlargement in single-rooted teeth with apical periodontitis. This prospective longitudinal study included 105 patients requiring root canal treatment of maxillary or mandibular single-rooted teeth with periapical lesion. After root canal treatment in a single session, pain intensity and tenderness were recorded daily for 7 days and on days 14 and 30. Edema was evaluated by two independent evaluators within 48 h, 72 h, and 7 days after treatment. Ordinal and logistic regressions were performed (p &lt; 0.05). Female gender (beta = 1.02; p &lt; 0.01), mandibular teeth (beta = 25.50; p &lt; 0.01), medium root canal amplitude (beta = 0.93; p = 0.03), and edema (beta = 1.88; p &lt; 0.01) were associated with increased postoperative pain and tenderness, while the use of analgesics (beta = -1.82; p &lt; 0.01) and time in days (beta = -0.23; p &lt; 0.01) were associated with a decrease in these signs and symptoms. Edema was considered a risk factor for analgesic requirement (Odds Ratio [OR] = 61.46; p &lt; 0.01). Factors such as gender, arch position, and root canal amplitude were associated with postoperative signs and symptoms. The use of analgesics was more required in edema and was associated with decreased pain.
