title: DOES SURGEON SPECIALIZATION CHANGE THE PROXIMAL HUMERAL OSTEO-SYNTHESIS APPROACH?

description: ABSTRACT Objective: To evaluate the choice of surgical approach among Brazilian orthopedists and whether shoulder surgery specialty training or duration of experience influences the decision-making. Methods: A questionnaire on the preferred approach and complications was administered to orthopedic surgeons with and without shoulder specialization training. The chi-square test or Fisher's exact test was applied. Results: We interviewed 114 orthopedists, 49 (43.0%) traumatologists, 36 (31.5%) specialist surgeons, and 29 (25%) shoulder surgery specialist residents. In cases of fracture without dislocation, specialized training and duration of experience did not influence the approach used (primarily deltopectoral). In cases of fracture/dislocation, 97.2% of the specialists versus 82.1% of the traumatologists opted for the deltopectoral approach (p = 0.034). In cases of fractures/dislocation, 92.5% of surgeons with more than 5 years of experience and 78.7% with less than 5 years of experience opted for the deltopectoral approach (p = 0.032). Conclusion: Specialization in shoulder surgery did not influence surgeons' approaches to manage fractures without dislocation. In cases of fracture/dislocation, shoulder surgery specialization training and duration of experience were associated with selection of the deltopectoral approach. Level of Evidence V, Expert opinion.

title: THE PERIODICITY OF CHEMICAL ELEMENTS AND THE MATERIALS PERFORMANCE: A COMPLEMENT FOR THE COMPREHENSION OF THE PERIODIC TABLE

description: The United Nations (UN) has proclaimed 2019 as the International Year of the Periodic Table of Chemical Elements (IYPT 2019). For that reason, it is considered pertinent to highlight the importance of the periodic system in the scientific and technological development of the chemistry; therefore, a discussion of some applications of the periodicity of the elements for designing new materials is carried out. In this work, some periodic trends of both molecules and complex structures of materials are discussed, by selecting different cases of the chemical periodicity applied to improve and design steels with higher wear resistance, prepare refractory materials and synthesize chalcogenides glasses, among others. Finally, the proposed subjects and the regularities argued in this work are considered complementary contexts of exceptional interest to motivate the meaningful learning of the periodic table taking into account the current scientific and technological researches.

title: Motor skills assessments: support for a general motor factor for the Movement Assessment Battery for Children-2 and the Bruininks-Oseretsky Test of Motor Proficiency-2

description: Abstract Objective To evaluate the construct validity and model-based reliability of general and specific contributions of the subscales of the Movement Assessment Battery for Children-2 (MABC-2) and Bruininks-Oseretsky Test of Motor Proficiency-2 (BOT-2) when evaluating motor skills across a range of psychiatric disorders. Methods Confirmatory factor analysis (CFA) and bifactor analysis were conducted on BOT-2 data from 187 elementary school students (grades 1 to 6) (mean age: 113 ± 20 months; boys: n = 117, 62.56%) and on MABC-2 data from 127 elementary school students (grade 1) (mean age: 76 ± 2 months; boys: n = 58, 45.67%). Results The results of the CFA fit the data for multidimensionality for the BOT-2 and presented poor fit indices for the MABC-2. For both tests, the bifactor model showed that the reliability of the subscales was poor. Conclusions The BOT-2 exhibited factorial validity with a multidimensional structure among the current samples, but the MABC-2 showed poor fit indices, insufficient to confirm its multidimensional structure. For both tests, most of the reliable variance came from a general motor factor (M-factor), therefore the scoring and reporting of subscale scores were not justified for both tests.

title: Barriers and facilitators perceived by people with bipolar disorder for the practice of exercise: a qualitative study

description: Abstract Introduction Exercising regularly has benefits for people with bipolar disorder. Nevertheless, as a group, these patients tend to be less physically active than the general population and little is known from the viewpoint of the patients about the barriers and facilitators to such a practice. Objective To know the barriers and facilitators perceived by people with bipolar disorder for the practice of exercise. Methods This study had a descriptive, qualitative, exploratory nature. The investigation method used for data collection was a semi-structured in-depth interview, using grounded theory as theoretical framework. Results The data analysis generated two main areas of interest: adherence to regular physical exercise (barriers and facilitators) and the participants’ exercise history and perception of disease management, as described below. The main findings were: most of our sample did not exercise regularly, nor knew how exercise can positively influence their disorder; with regard to adherence to physical exercise, the presence of symptoms and stigma were the most important barriers to the practice of physical exercise. Social support, especially from family and friends, could be a facilitator to the practice of exercise. Conclusions Even considering the limitations for generalization of qualitative and exploratory studies, understanding perceived barriers and facilitators for the practice of exercise among people who suffer with bipolar disorder may contribute to the promotion of activities in which people with mental illness can participate.

title: Effect of Omega 3 and Vitamin B12 on the spermogram, histomorphometry of the reproductive organs and body temperatures with infrared thermography in Wistar rats

description: ABSTRACT The objective of this study was to study the effect of Omega 3 and vitamin B12 on spermogram, histomorphometry of reproductive organs and body temperature with infrared thermography in Wistar rats. Sixteen rats were used in four groups (n= 4) who received daily injections for 30 days. Control Group - saline solution; Group Omega 3 - fish oil 1g/kg; Group B12 - vitamin B12 3μg and Group Omega 3 + B12 - fish oil 1g/kg and vitamin B12 3μg. Thermographic images of body were obtained. On the 30th day the rats were sacrificed and analyzes of sperm morphology and histomorphometry were performed. Data were submitted to analysis of variance and Tukey's test at 5%. The surface temperature of the scrotum was higher in group B12 (P&lt; 0.05). There were no differences between groups (P&gt; 0.05) for eyeball temperatures. There was a correlation between scrotal temperature and distal cytoplasmic droplet (P= 0.678). Elevation of scrotum temperature results in an increase in the percentage of distal cytoplasmic droplets. The temperature of the eyeball is not significantly influenced by Omega 3 and vitamin B12. Omega 3 reduces the seminiferous epithelium and vitamin B12 minimizes this effect.

title: ISOLATION AND FRACTIONATION OF HUMIC SUBSTANCES PRESENT IN WATER WITH THE USE OF ANION-EXCHANGE RESINS AND ULTRAFILTRATION

description: ABSTRACT Natural water treatment requires emphasis on humic substances (HS) removal because of disinfection by-product formation possibilities. Thus, detailed research on HS structure and properties is necessary. Two model solutions of different origin were used in this study. A100, A200, A400, A870 and DEAE-cellulose anion exchange resins were used for the one-stage isolation of HS. Model solutions and eluates from the respective resins were subjected to filtration using regenerated cellulose 1, 5 and 10 kDa MWCO ultrafiltration membranes. The results allowed ranking of analyzed anionites according to the isolation capacity of HS: DEAE &gt;&gt; A870 &gt; A100 &gt; A400 &gt; A200. Analysis of the HS molecular size distribution shows that hydrophilic compounds of low molecular weight (MW) are dominant in natural water, whereas in the Aldrich humic acid solution and in the eluates after each resin, large MW hydrophobic compounds are predominant.

title: IMPROVEMENT OF THE BIOCHEMICAL METHANE POTENTIAL OF FOOD WASTE BY MEANS OF ANAEROBIC CO-DIGESTION WITH SWINE MANURE

description: ABSTRACT Food waste (FW) has potential for use by means of anaerobic digestion (AD). However, some characteristics of FW affect process stability and methane (CH4) production. Using biochemical methane potential (BMP) tests, this study assessed the improvement of CH4 production and hydrolysis of FW by means of anaerobic co-digestion (AcoD) with swine manure (SM). Different FW:SM ratios were studied under conditions with (WN) and without (NN) nutrients. The highest CH4 production was obtained for the FW:SM 60:40 ratio in the WN and SN conditions with values of 72.87 and 62.83 mL CH4 g VS-1, respectively. This showed that AcoD of FW with SM presented synergistic effects, since increases of 27 (WN) and 13% (NN) were obtained in comparison with the mono-digestion of FW. There was also an improvement in the process stability (α index &gt; 0.7), but there were no favorable effects with respect to the hydrolysis of FW.

title: EFFECT OF THE COMBINATION OF ENZYMATIC PREPARATIONS ON THE AQUEOUS EXTRACTION YIELD OF THE OIL FROM THE PULP OF Euterpe oleracea FRUIT

description: ABSTRACT This work aimed to study the effect of the combination of four commercial enzymatic preparations (Celluclast 1.5 L, Viscozyme L, Ultrazym AFP, and Shearzyme 500 L) on the aqueous extraction yield of the oil from the pulp of Euterpe oleracea fruit. The enzymatic preparations were tested individually and in combinations of two, three and four, in triplicate. The negative control presented the lowest extraction yield (34.91%). The tests performed with the isolated enzymatic preparations presented an average increase in the extraction yield of approximately 30% compared to the negative control, confirming the important role of the enzymes in the extraction process. The tests performed with the combination of more than two enzymatic preparations increased the extraction yield by approximately 90% compared to the negative control, demonstrating the advantage of using combinations of enzymes. Among the different tests, those performed with the combination of three enzymatic preparations, including the cellulase class-type enzyme, Celluclast 1.5 L, stood out by presenting a high extraction yield (&gt; 65%) and being statistically equal to the one using all four, which is interesting for the industry due to the reduced cost of the process.

title: The Use Of Team-Based Learning As An Evaluation Method On The Medicine Course

description: ABSTRACT Adult education presupposes the use of active teaching and learning methodologies that propose challenges to be overcome by students, with the teacher acting as facilitator and guiding the process. The objective of this study was to report the use of Team-Based Learning (TBL) as one of the methods used to evaluate students in the subject Teaching-Service interaction in the Community (IESC), of the Medicine Course. TBL was applied with two classes IESC classes. The experience gained through the application of TBL, instead of the traditional test, demonstrated some relevant aspects, for example: in the preparation, it is fundamental that the student is committed to studying the proposed topics; the use of application was an innovative strategy that motivated the academics to participate actively in the process; the performance of the team took precedence over individual performance. The concepts learned were put into practice in the IESC field classes, since they involve observation of real clinical cases in the Health Units and in the community, using the theoretical knowledge acquired, in the interventions. The application of TBL proved to be an efficient evaluation method in the IESC, which is based on the perspective of interaction and collaborative processes. The use of the technological resource as a tool sparked the students’ interest, minimizing the stress that usually occurs during the traditional assessment. It is important that health training courses provide a review, to ensure that traditional teaching practices are not given too much weight, at the expense of active learning practices.

title: Social inequality, human development and fertility pattern in Brazil, 2000-2010

description: Abstract Objectives: to analyze the fertility pattern in Brazil and its relationship with human development in the Brazilian federation units in 2000 and 2010. Methods: this is an ecological study whose unit of analysis was the Brazilian Federative Units in the period of 2000 and 2010. The fertility was assessed considering the social (HDI), inequality, (Gini, Theil and Income Ratio) and fertility indicators (fertility rate and mean age of fertility). Results: Brazil has been experiencing a rapid fertility transition. The pattern of fertility curves changed in all Federative Units between 2000 and 2010, with a reduction in cusp size and postponement of fecundity. This change was more evident among the Federative Units with better development and lower inequality. The correlation between social and fertility indicators lost strength in the period, corroborating the transition hypothesis. Conclusions: there is a direct relation between the fecundity and inequality indicators, and inversing human development. Changes should be taken in consideration in the age structure of the population, as well as inequality indicators, for better planning in public policies for public health.

title: Análise do Impacto das Políticas de (Des)Oneração da Folha de Pagamento na Economia Brasileira

description: Abstract In 2012 the Brazilian Federal Government adopted a payroll tax exemption, but in 2015 such policy was reviewed and changed by removing part of the exemption. The goal is to evaluate the economic impacts of these policies using a computable dynamic and multisectoral general equilibrium model developed for the Brazilian economy. The results show that the exemption policy would imply a cumulative growth impact of 0,34% in GDP, while the new policy leads to a cumulative growth impact −0,37%. This result is explained by the sectoral distortions resulting from the changes in the exemption policy which increases the cost of payroll in capital-intensive sectors as well as in their production cost of these goods, leading to reductions in the aggregated investment rate.

title: Knowledge management for the sustainable development of the semi-arid region in Northeastern Brazil

description: ABSTRACT: The objective of this study was to analyze the knowledge management perception in managers of a public university in the Brazilian Northeastern Semiarid Region, especially their tactical and strategic processes to produce knowledge about this region. The analysis was conducted according to the perspective of administrators at this university with a view to the sustainable development of the region. This was a qualitative descriptive study. All data were collected through structured interviews, using a questionnaire based on the Knowledge Management Diagnosis as a structuring model. Results showed that Knowledge Management is still a maturing practice. However, knowledge management is making institutional changes feasible and generating organization capacity to implement solutions and promote the sustainable development of the semi-arid region in the Northeastern Brazil.
