title: Public policies, increase in land value and metropolization: the Metropolitan Region of Belo Horizonte and the expansion of the industrial vector

description: Abstract The specificities of land in relation to other goods constitute unique processes of land value increase and land commercialization, in which the involvement of space production agents is a structuring element in the formation of prices. The State, one of these agents, plays a remarkable role, as it has the power to control the possible uses of land and, consequently, to induce activities and enterprises that generate capital attraction. This article discusses the relationship between the State’s action, the increase in land value and Belo Horizonte’s expansion, from its inaugural plan to metropolization, especially in the “west vector”, associated with industrial activities since the beginning of its expansion.

title: Comprehension of informed consent in clinical research

description: Abstract The informed consent form (ICF) is a document which explicitly confirms the consent of a participant in a research project, and should contain all necessary information clarifying the study in which the subject intends to participate. This study evaluates the level of comprehension of an ICF signed by 146 volunteers using a self-administered instrument. The average age of the sample was 47.29 years, and there was a prevalence of women (67.2%), incomplete primary education (53.4%) and no private health care (93.2%). The mean score of correct answers of 146 respondents was 53.1%. There was no association between the percentage of correct answers and the variables of gender, age, education and time of response. There was a significant association between taking the ICF home and the percentage of correct answers. The average value of correct answers found was not acceptable and educational measures must be implemented, seeking an increase in comprehension and the safety of participants.

title: CONTAMINATION POTENTIAL OF SPECIFIC IONS IN SOIL TREATED WITH REJECT BRINE FROM DESALINATION PLANTS

description: ABSTRACT Percolation columns constructed in the Laboratory can predict the degree of contamination in soil due to reject brine disposal and can be a tool for reducing environmental impacts. This study aim to evaluate the mobilization of ions in reject brine from desalination process by reverse osmosis. The mobilization of the contaminant ions in the saline waste was studied in glass percolation columns, which were filled with soil of contrasting textures (eutrophic CAMBISOL, typic dystrophic Red OXISOL, ENTISOL Quartzipsamment). Experiments ware repeated three times each, and the initial and final concentrations of the ion contaminants were analyzed. The pollution potential of this wastewater was determined by the retardation factor and dispersion-diffusion coefficient of K+, Cl- and Na+ for each studied soil. The differences in the displacement curves of the ions present in the saline waste among various soil types were analyzed. The Entisol Quartzipsamment showed a higher forward speed of the ions K+ and Cl- (greater retardation factor, i.e., greater power of the subsurface contamination for these ions). In typic dystrophic Red OXISOL, the ions move with greater ease and therefore produced greater groundwater contamination. In eutrophic CAMBISOL, the low coefficient of diffusion-dispersion in all ions was evaluated (i.e., reduced ion mobility is directly influenced by their exchangeable levels).

title: Brasília and its territory: assimilation of english planning principles into the initial plans for satellite towns

description: Abstract Appropriation of international models and principles by the urban plan of Brasília is one of the topics within the historiography of the capital of Brazil and has contributed to a broader discussion about possible specificities of the modern movement in the country. However, this discussion has tended to be restricted to the design of the nucleus of the city outlined by Lucio Costa in 1957. The aim of this paper is to go beyond the customary emphasis on the Pilot Plan to analyze proposals for organizing the territory of the Federal District and creating satellite towns between the late 1950s and early 1960s. The analysis points out the peculiar assimilation of a set of English ideas and concepts that were in circulation in the field of urban and regional planning during the first half of the twentieth century.

title: Impaired Right Ventricular Function in Heart Transplant Rejection

description: Abstract Background: The practice of screening for complications has provided high survival rates among heart transplantation (HTx) recipients. Objectives: Our aim was to assess whether changes in left ventricular (LV) and right ventricular (RV) global longitudinal strain (GLS) are associated with cellular rejection. Methods: Patients who underwent HTx in a single center (2015 - 2016; n = 19) were included in this retrospective analysis. A total of 170 biopsies and corresponding echocardiograms were evaluated. Comparisons were made among biopsy/echocardiogram pairs with no or mild (0R/1R) evidence of cellular rejection (n = 130 and n = 25, respectively) and those with moderate (2R) rejection episodes (n=15). P-values &lt; 0.05 were considered statistically significant Results: Most patients were women (58%) with 48 ± 12.4 years of age. Compared with echocardiograms from patients with 0R/1R rejection, those of patients with 2R biopsies showed greater LV posterior wall thickness, E/e’ ratio, and E/A ratio compared to the other group. LV systolic function did not differ between groups. On the other hand, RV systolic function was more reduced in the 2R group than in the other group, when evaluated by TAPSE, S wave, and RV fractional area change (all p &lt; 0.05). Furthermore, RV GLS (−23.0 ± 4.4% in the 0R/1R group vs. −20.6 ± 4.9% in the 2R group, p = 0.038) was more reduced in the 2R group than in the 0R/1R group. Conclusion: In HTx recipients, moderate acute cellular rejection is associated with RV systolic dysfunction as evaluated by RV strain, as well as by conventional echocardiographic parameters. Several echocardiographic parameters may be used to screen for cellular rejection.

title: Mandibular and temporomandibular morphologic characteristics of patients with suspected unilateral condylar hyperplasia: a CT study

description: ABSTRACT Introduction: Facial asymmetry associated with unilateral condylar hyperplasia (UCH) is a complicated clinical condition. Objective: The objective of this study was to describe morphological characteristics of the mandible and the temporomandibular joint in patients with facial asymmetry, using computed tomography and 3D reconstruction. Methods: A retrospective observational study was performed with patients displaying facial asymmetry evaluated by single photon emission computed tomography (SPECT)/CT analysis, for suspected UCH, between 2015 and 2018. The following variables were compared between the affected side (producing the asymmetry) and the contralateral side (side to where the jaw is deflected): condylar length, condylar medial and lateral pole length, mandibular ramus length, intra-articular spaces, articular eminence height and position of the posterior wall of the glenoid fossa. Results: Forty-three patients (21 women, mean age: 20.7 ± 7.25 years) with facial asymmetry were included, 19 patients presented right side deviation and 24 patients had left side deviation. Condylar length, lateral pole length, the sum of maximum values and articular eminence height were greater in the affected side (p&lt; 0.05). A positive correlation was found between the position of the posterior wall of the glenoid fossa and the articular eminence height in the affected side (r = 0.442). Conclusions: In patients with suspected UCH, evaluated through CT, craniofacial measurements showed significantly larger condylar length and the condylar sum of maximum values in the affected side. A positive correlation was found between the increased dimensions of the articular eminence and the more posterior position of the glenoid fossa in the affected side.

title: Comparative study of two anaesthetic protocols involving conventional and Vazirani-Akinosi alveolar inferior nerve block for lower third molar extraction

description: INTRODUCTION: The inferior alveolar nerve block has a high percentage of failure in dentistry. To improve this ratio, has been studied different alternatives, as different techniques, as well as anesthetics. OBJECTIVE: Evaluate two different techniques (conventional technique and Vazirani-Akinosi) for inferior alveolar nerve block, and compare them regarding their effectiveness and quantify the percentage of positive aspirations in both techniques. MATERIAL AND METHOD: 160 patients were evaluated for both sex, with 80 undergoing Vazirani-Akinosi technique plus buccal nerve block (G1), and 80 to conventional inferior alveolar nerve block plus buccal nerve block (G2), both groups using a combination of 4% articaine with 1:100.000 epinephrine to buccal nerve block and 2% lidocaine with 1:100.000 epinephrine to inferior alveolar nerve block. We evaluated the amount of positive aspirations, the effectiveness or not of anesthesia (pain) and when it occurred during the surgical procedure. RESULT: There were no statistically significant differences (p = 0.2453) between G1 and G2 observing the positive aspiration. It was obtained efficiency of 90% for both techniques. CONCLUSION: No significant difference between the conventional alveolar inferior nerve block technique and Vazirani-Akinosi alveolar nerve block technique considering the amount of positive aspirations and efficacy, and the use of 4% articaine with 1:100.000 epinephrine in buccal nerve block possibly increased the anesthetic efficacy of both techniques.

title: Vitamin D Deficiency and Cardiovascular Diseases

description: Abstract Vitamin D is considered a steroid hormone with a broad spectrum of action in the human body. Its action arises from the binding of its active metabolite (1α,25-dihydroxyvitamin D) to its receptor (VDR), which is present throughout the body, including vascular smooth muscle cells and cardiomyocytes. Initially, vitamin D deficiency was related only to changes in the musculoskeletal system, but in recent years, researchers have demonstrated its relationship with several pathologies related to other systems, such as cardiovascular diseases. The objective of this study is to review vitamin D’s pathophysiology, describe its relationship with cardiovascular diseases based on the most recent publications, and highlight the results of vitamin supplementation in the prevention of such pathologies.
