title: The effect of a 3% hydroxyapatite paste prophylaxis after different root-scaling procedures in periodontics

description: Abstract Introduction Root-scaling procedures on the root surface show to increase root surface roughness during instrumentation. The use of a prophylactic paste reduces the roughness. Objetive This study evaluated the influence of prophylaxis paste on the surface roughness of root dentin after hand instruments (HI), ultrasonic scalers (US) and rotational instruments (RI) were applied to root surfaces. Material and method Fifty bovine roots were prepared and randomly divided into 10 groups (n=5) in which instrumentation with HI, US, or RI was carried out with or without prophylaxis using either conventional or 3% hydroxyapatite paste; additionally, a control group without treatment was included. The Ra and Rz roughness values were measured using a perfilometer. The morphological aspects of the root surfaces were analysed qualitatively by scanning electron microscopy (SEM). Data were analysed using two-way ANOVA followed by Tukey’s test (α = 0.05). Result The scaling method and the prophylaxis procedure significantly influenced (p &lt; 0.05) root surface roughness. Treatment with US and prophylaxis with 3% hydroxyapatite paste resulted in lower values of Ra (0.14 μm ± 0.02 μm) and Rz (0.89 μm ± 0.18 μm) compared to the other groups. SEM analysis showed smoother and more homogeneous surfaces in the groups with prophylaxis compared to the groups without prophylaxis. There were no substantial differences between the results of applying different pastes. Conclusion The prophylaxis procedure performed with the experimental paste containing 3% hydroxyapatite reduced the roughness of root surfaces treated with HI, US and RI at the same level as the conventional prophylactic paste.

title: Evolutive Study of Rheumatic Carditis Cases Treated with Corticosteroids in a Public Hospital

description: Abstract Background: Rheumatic carditis is a challenge for treatment and secondary prophylaxis, due to severe valve sequelae. Objective: To evaluate the cases of rheumatic carditis in patients under 18 years old treated with corticosteroids. Methods: An observational, longitudinal and retrospective study was carried out on the profile of patients, in the period of 2000-2015. We selected those who received corticosteroid therapy at immunosuppressive doses, for the treatment of carditis and were aged 5 to 18 years. Data were extracted from medical records. Calculations of: averages, standard deviations, medians and interquartile ranges, ratios and 95% confidence intervals were obtained. Chi-square and Wilcoxon tests were applied for comparisons. The level of significance was 5%. Results: Of the 93 cases, 93.53% developed moderate or severe carditis. Mitral regurgitation was detected in 100% of the sample. Pulse therapy was administered in 11.83%. Surgery was performed in 23.69% of patients: mitral, aortic and/or tricuspid valve repair or replacement. The evolution of the cases was favorable in 70.96%. There was a good response among those who received only clinical treatment and those who belonged to the surgical group. The comparison of the initial and posterior valve lesions to the corticoid use was statistically significant (p &lt; 0.001). A difference between the ejection fraction medians was observed (p = 0.048). Hospitalization was required twice or more for 45.16% of the patients. The mortality rate was 5.38%. Conclusions: The patients showed significant clinical improvement. The treatment was effective, reducing trivalvular impairment.

title: Indexing of clinical trials in LILACS: Assessment of 721 articles published in cardiology journals

description: Abstract Systematic reviews are considered the highest level of evidence for decision making in health care issues. One of the first steps of a SR involves identifying all relevant clinical trials on the topic of interest. However, the retrieval of clinical trials in a database partially depends on the article indexing quality. The aim of this article is to evaluate the adequacy of indexing of clinical trials as a publication type in the LILACS database in a sample of articles published in cardiology journals. This cross-sectional study analyzed the indexing quality of clinical trials published between 2008 and 2009 in cardiology journals indexed in LILACS. Two independent reviewers identified and reclassified all original studies published in these journals as being clinical trials or other types of studies. The result of their classification was compared with the indexing publication type produced by LILACS. A total of 721 articles published in 11 cardiology journals were included. The reviewers classified 63 articles as clinical trials; 44 of these were correctly indexed in LILACS, while 19 were indexed as other types of studies (false negatives). The reviewers classified 658 articles as non-clinical trials; 651 were correctly indexed and 7 were incorrectly indexed in LILACS as being clinical trials (false positives). The sensitivity, specificity and global accuracy of LILACS indexing were 69.8%, 98.9% and 96.4% (695/721), respectively. Almost one third of the clinical trials published in LILACS-indexed Cardiology journals are not adequately indexed. The indexing quality of the studies published in these journals must be improved.

title: School Noise between Fences and Walls: what is free in school?

description: Abstract: Analysing the experience of an image and sound project developed in a public school in the north zone of Rio de Janeiro, this study features reflections on the processes of signification of freedom in school. During the project, students were invited to produce images and sounds related to the theme being free in school. The material produced afforded relevant elements for an analysis of the contribution of youngsters to significations that go beyond a view of school composed merely of students and masters explicators, a term used by Jacques Rancière to analyse the role of teachers. Based on the images made by those students, the study proposes interpretations of schools as spacetimes of conversations.

title: The Adoption of Interorganizational cost Management in a Vehicle Assembly plant in the Greater Region of ABC

description: ABSTRACT It is necessary that organizations define strategies for cost management in interorganizational relationships existing in the Supply Chain (SC), focusing not only on reducing individual costs, but on improviving the competitive advantage of these chains. The Interorganizational Cost Management (ICM) focuses on minimizing costs, creating competitive advantages in relation to competing chains. The objective of this study was to check how the ICM has been applied in the chain of an automotive assembly plant in the Greater Region of ABC (state of São Paulo). In conducting the exploratory research, we inquired of 10 managers in the areas of Procurement, R&D, Supplier Quality Engineering, Logistics and Finance, to identify and analyze the aspects that characterize the practice of ICM in the assembly plant chain. We found that the ICM is adopted in all phases of the life cycle of the product, focused on cost reduction and continuous improvement of processes and products. The results show that the practice of ICM makes the relationships between the assembly plant and its suppliers more profitable and sustainable, and it is a tool capable of delivering benefits to the entire chain. Therefore, it should be included in the strategic management of companies.

title: METHODOLOGY FOR GREEN AND BUILT VOLUME ANALYSIS

description: ABSTRACT Today, in some Brazilian cities, there is the possibility of using high-resolution data and automated classification based on spectral bands. Thus, this article aims to evaluate the association of the NDVI(normalized difference vegetation index) to the use of LiDAR, in order to analyze urban vegetation cover and the changes of the local landscapes. It was observed that the association of the high spatial resolution of an aerophotogrammetric image to the spectral response in the near infrared range allowed the vegetation to be identified. This enabled the documentation, visualization and analysis of a location’s phenomenon, facilitating the investigation of spatial relationships through representation by maps, charts, especially for simulating possible spatial scenarios and thus permitting the evaluation of interventions and predictions to be made, assisting projects or proposed laws and urban parameters.

title: Evaluation of membranes for the treatment of oilfield-produced water

description: Large quantities of water are generated during oil extraction. Reinjection of this effluent is frequently the most suitable option for environmental considerations. For this purpose, the water produced must have characteristics that will prevent the plugging of the reservoir rocks, i.e., suspended solids and oil and grease content must be lower than 5 mg L-1. This work evaluated the performance of membranes for water treatment, based upon long-term experiments with real effluent, evaluating the permeate flux over time and the effluent characteristics. The results indicated that it is possible to obtain a permeate flux with suspended solids content with less than 1 mg L-1 oil and a grease concentration in the range of 1 to 3 mg L-1 using membranes with a pore size of 0,1 (m. After 50 hours of permeation, the permeate fluxes obtained with the polymeric and ceramic membranes were equal to 50 and 300 L h-1 m-2, respectively. With a chemical regeneration procedure, it was possible to recover 95% of the ceramic membrane's original permeability and 30% of the polymeric membrane's permeability. Considering the permeate quality, the regeneration efficiency of the membrane and the fluxes achieved, it is possible to point out the use of ceramic membranes as a potential technology for treating oilfield-produced water, and it has the advantage of being a compact and robust process.
