title: Infrared Light-Emitting Diode (LED) Effects on Orthodontic Tooth Movement

description: Abstract The present study aimed to analyze the effect of LED phototherapy on the presence of hyalinization and root resorption during orthodontic tooth movement (OTM) in rats and to measure the amount of tooth movement. Eighty rats were allocated into two groups: LED and control (CON), where the LED rats were irradiated with infrared LED (850 nm, 30 mW) for 5 min during the first five days of OTM and where controls were not irradiated. Both groups were subdivided into four subgroups (n=10) according to the date of euthanasia (4, 7, 14 and 21 days). Five out of ten LED21 and five of ten CON21 rats were submitted to micro-computed tomography (μCT); μCT scans were taken on days 0, 7, 14 and 21. For histological study, maxillae were processed to light microscopy using Hematoxylin-Eosin (HE) and Tartrate-Resistant Acid Phosphatase (TRAP) histochemistry. The amount of tooth movement did not differ between LED and CON. Hyalinization was observed at the pressure areas in both groups, and it did not show a statistically significant difference between the groups. Root resorption was also observed in both groups after 7 days and it did not represent any differences between the two groups. LED phototherapy was not able to increase the amount of OTM. Similar characteristics of hyalinization and root resorption were observed in both groups.

title: Relationship between pulmonary function, functional independence, and trunk control in patients with stroke

description: ABSTRACT Stroke often leads to abnormalities in muscle tone, posture, and motor control that may compromise voluntary motor function, thus affecting the motor control required for maintaining the synergy of both peripheral and respiratory muscles. Objective To evaluate respiratory muscle strength, pulmonary function, trunk control, and functional independence in patients with stroke and to correlate trunk control with the other variables. Methods This was a cross-sectional study of patients diagnosed with stroke. We assessed respiratory muscle strength, trunk control as assessed by the Trunk Impairment Scale, spirometric variables, and the Functional Independence Measure. Results Forty-four patients were included. Pulmonary function and respiratory muscle strength were significantly lower than predicted for the study population, and the mean Trunk Impairment Scale score was 14.3 points. The following significant correlations were found between the variables: trunk control vs. maximal inspiratory pressure (r = 0.26, p &lt; 0.05); trunk control vs. forced vital capacity (r = 0.28, p &lt; 0.05); trunk control vs. forced expiratory volume in one second (r = 0.29, p &lt; 0.05), and trunk control vs. the Functional Independence Measure (r = 0.77, p &lt; 0.05). Conclusion The present study showed that respiratory muscle strength, pulmonary function, functional independence, and trunk control are reduced in patients diagnosed with stroke.

title: An overview of the appendicular skeletal anatomy of South American titanosaurian sauropods, with definition of a newly recognized clade

description: Abstract: In the last two decades, the number of phylogenetically informative anatomical characters recognized in the appendicular skeleton of titanosaurian sauropod dinosaurs has increased dramatically with the discovery of new and comparatively complete specimens. Here we provide an overview of the appendicular skeletal morphology of South American titanosaurs and discuss its significance for phylogenetic reconstruction. The appendicular skeletal diversity of South American titanosaurs is substantially greater than was initially appreciated. Moreover, some regions of the appendicular skeleton, such as the pes, exhibit remarkable variability in form. Multiple synapomorphies of Titanosauria and the less inclusive clades Lithostrotia and Saltasauridae consist of characters of the girdles and limbs. Although the phylogenetic definitions of titanosaurian clades such as Saltasaurinae and Lognkosauria are stable, the taxonomic content of these clades has varied in recent analyses depending on the phylogenetic topology recovered. Within Titanosauria, the results of four recent, largely independent analyses support the existence of a derived titanosaurian lineage distinct from the ‘Saltasaurinae line,’ which is herein termed Colossosauria. At present, this clade is mainly comprised by taxa within Lognkosauria and Rinconsauria, and is useful in discussions of titanosaurian lower-level relationships.

title: PRECORDIAL PAIN, LEUKOCYTOSIS AND BICYTOPENIA IN A TEENAGER WITH SYSTEMIC JUVENILE IDIOPATHIC ARTHRITIS UNDER IMMUNOSUPPRESSIVE THERAPY

description: ABSTRACT Objective: To highlight the importance of the new classification criteria for the macrophage activation syndrome (MAS) in systemic juvenile idiopathic arthritis in order to reduce morbidity and mortality outcome related to this disease. Case description: A 12-year-old female patient with diagnosis of systemic juvenile idiopathic arthritis under immunosuppression therapy for two years developed cough, acute precordial chest pain, tachypnea, tachycardia and hypoxemia for two days. Chest tomography showed bilateral laminar pleural effusion with bibasilar consolidation. The electrocardiogram was consistent with acute pericarditis and the echocardiogram showed no abnormalities. Laboratory exams revealed anemia, leukocytosis and increased erythrocyte sedimentation rate, as well as C-reactive protein rate and serum biomarkers indicative of myocardial injury. Systemic infection and/or active systemic juvenile idiopathic arthritis were considered. She was treated with antibiotics and glucocorticoids. However, 10 days later she developed active systemic disease (fever, evanescent rash and myopericarditis with signs of heart failure) associated with macrophage activation syndrome, according to the 2016 Classification Criteria for Macrophage Activation Syndrome in Systemic Juvenile Idiopathic Arthritis. She was treated for five days with pulse therapy, using glucocorticoids, immunoglobulin and cyclosporine A, with improvement of all clinical signs and laboratory tests. Comments: Myopericarditis with signs of heart failure associated with MAS is a rare clinical presentation of systemic juvenile idiopathic arthritis. Macrophage activation syndrome occurs mainly during periods of active systemic juvenile idiopathic arthritis and may be triggered by infection. Knowledge about this syndrome is crucial to reduce morbidity and mortality.

title: The influence of family background on the access to Technical and Vocational Education

description: ABSTRACT This work investigates the influence of family background variables (father’s schooling, mother’s schooling, and family income) on the result of a student’s application to access a Brazilian institution of technical and vocational education. The research used secondary data carried out 19,226 observations, and formulated a conceptual model with three hypotheses. The results were presented in three stages: I - separation of campuses into clusters; II - analysis of multiple regressions; and, III - analysis of logistic regressions. One of the hypotheses was rejected and two were confirmed, indicating that there is a positive effect of the variables family income and father’s schooling, but no statistical significance for the variable mother’s schooling.

title: Sprouting of pre-sprouted sugarcane seedlings and micrometeorological variables under photo-selective nets

description: ABSTRACT Sugarcane is a grass species that stands out worldwide in the production of ethanol. Brazil is the world’s largest producer and leader in exports, responsible for more than 50% of the products that are marketed worldwide. The objective of this study was to investigate the effect of photo-selective nets on micrometeorological variables and on sprouting of pre-sprouted sugarcane seedlings. The experiment was carried out in a protected environment at Universidade Federal Rural de Pernambuco - UFRPE, in a completely randomized design. Seedlings of cultivar RB92579 were obtained by the technique of production of pre-sprouted seedlings. The protected environment was divided into four modules corresponding to the treatments: covered with anti-UV low-density polyethylene plastic: + Solpack® red ultranet net, + Solpack® white net, + Solpack® freshnet net and without shade net. Micrometeorological data of air temperature and substrate temperature were recorded in each module. The first count of emergence, sprouting speed index and sprouting percentage were calculated. Principal component analysis was used to verify the association between the cultivation modules and the micrometeorological and sprouting variables of the seedlings. Air temperature in the protected environment was 8.7% higher than that in the external environment. The white net led to sprouting of 78.93%. The substrate temperature above 30.4 °C favored seedling sprouting. The modules with white net and red ultranet net favored seedling sprouting.

title: Determinants of the use of technical assistance by Brazilian family famers in 2014

description: Abstract This paper analyzes the determinants of the use of technical assistance by Brazilian family farmers in 2014. Using data from the National Survey by Household Samples (PNAD) of 2014, a qualitative probit regression model was estimated, allowing the identification of the magnitude and significance of the effect of each explanatory variable on the probability of using technical assistance in the last agricultural work developed in the enterprise. The results show that the socioeconomic profile, the productive characteristics and the location of the family farmer affect significantly the probability of using technical assistance. It was observed that the fact that an individual with non-white skin, who has as main marketing channel direct sale to the consumer, be transferee or present unspecified condition in relation to the land, has advanced age or low education or income per capita has a statistically significant effect of reducing the probability of using technical assistance. On the other hand, the fact that the individual has as a main marketing channel the sale to companies or cooperatives, has temporary employees or he/she is located in the south region increases this probability. It is concluded, finally, that in-depth studies to better understand these effects can provide support for the improvement of technical assistance actions.

title: Risk Factors for Major Adverse Events after Surgical Closure of Ventricular Septal Defect in Patients Less than 1 Year of Age: A Single-Center Retrospective

description: Abstract Objective: To reveal the risk factors that can lead to a complicated course and an increased morbidity in patients &lt; 1 year old after surgical ventricular septal defect (VSD) closure. Methods: We reviewed a consecutive series of patients who were admitted to our institution for surgical VSD closure who were under one year of age, between 2015 and 2018. Mechanical ventilation (MV) time &gt; 24 hours, intensive care unit (ICU) stay longer than three days, and hospital stay longer than seven days were defined as “prolonged”. Unplanned reoperation, complete heart block requiring a permanent pacemaker implantation, sudden circulatory arrest, and death were considered as significant major adverse events (MAE). Results: VSD closure was performed in 185 patients. The median age was five (1-12) months. There was prolonged MV time in 54 (29.2%) patients. Four patients (2.2%) required permanent pacemaker implantation. Hemodynamically significant residual VSD was observed in six (3.2%) patients. Extracorporeal membrane oxygenation-cardiopulmonary resuscitation was performed in one (0.5%) patient. Small age (&lt; 4 months) (P-value&lt;0.001) and prolonged cardiopulmonary bypass time (P=0.03) were found to delay extubation and to prolong MV time. Low birth weight at the operation was associated with MAE (P=0.03). Conclusion: Higher body weight during operation had a reducing effect on the MAE frequency and shortened the MV duration, ICU stay, and hospital stay. As a conclusion, for patients who are scheduled to undergo VSD closure, body weight should be taken into consideration.

title: Impacts of Different Forms of Poverty Measurement on Variatons of the Personal Wellbeing Index

description: Abstract The aim of this study is to analyze the impact of different forms of poverty measurement on variations of the Personal Well-being Index (PWI) of poor and non-poor individuals. Comparative analyzes were performed with the Student's t-test and Multivariate Analysis of Variance (MANOVA) in a comparative perspective of different forms of poverty measurement. The sample consisted of 731 Brazilian subjects, 57% from a northeastern state and 43% form a southern state, with a mean age of 36,7 years (SD = 16,0). Monetary and multidimensional measures of poverty were used. The results indicate that, regardless of the form of poverty measurement, there is a negative impact on PWI. However, the use of the multidimensional perspective seems to have a greater capacity to identify the psychosocial impacts of poverty.

title: Pervious concrete made with electric furnace slag (FEA): mechanical and hydraulic properties

description: Abstract The objective of this work is to make feasible the use of FEA slag instead of the conventional bulk aggregate in the pervious concrete (PC) production, reaching the minimum parameters required by NBR16416/2015 and ACI 522R-10. This substitution would minimize the use of natural aggregates, besides taking advantage of a residue that has no specific destination. In order to reach the objective, three FEAs with different grain sizes were chosen: 6-10 mm (A), 10-20 mm (B) and finally a mixture of the two previous ones (C) in the proportion 30-70 respectively. In order to evaluate its mechanical behavior, tests of compressive strength and flexural tensile tests were carried out, while the evaluation of the hydraulic behavior, porosity and constant head permeability test were performed. The compressive strength varies from 19-31MPa and 3-4MPa for flexural tensile strength was obtained. In hydraulic terms, the porosity varied from 15-20% and the permeability coefficient was 10-12mm/s. There is also a direct influence of grains of size less than 4.8 mm (small aggregate) on the compressive strength and permeability of PCs. At the end of the results, it was possible to establish a correlation between the compressive strength, the permeability and the percentage of grains inferior to 4.8mm (sand%), being this positive in relation to the studied variables, that is, the mechanical and hydraulics. Therefore, it has been concluded that the total substitution of conventional aggregates by FEA in CoPe manufacturing will comply with the minimum parameters of NBR 16416/2015.
