title: Ebstein's Anomaly: "The One and a Half Ventricle Heart"

description: Abstract Objective: Ebstein's anomaly remains a relatively ignored disease. Lying in the 'No Man's land' between congenital and valve surgeons, it largely remains inadequately studied. We report our short-term results of treating it as a 'one and a half ventricle heart' and propose that the true tricuspid annulus (TTA) 'Z' score be used as an objective criterion for estimation of 'functional' right ventricle (RV). Methods: 22 consecutive patients undergoing surgery for Ebstein's anomaly were studied. Echocardiography was performed to assess the type and severity of the disease, tricuspid annular dimension and its 'Z' score. Patients were operated by a modification of the cone repair, with addition of annuloplasty, bidirectional cavopulmonary shunt (BCPS) and right reduction atrioplasty to provide a comprehensive repair. TTA 'Z' score was correlated later with postplication indexed residual RV volume. Results: There was one (4.5%) early and no late postoperative death. There was a significant reduction in tricuspid regurgitation grading (3.40±0.65 to 1.22±0.42, P&lt;0.001). Residual RV volume reduced to 71.96±3.8% of the expected volume and there was a significant negative correlation (rho −0.83) between TTA 'Z' score and indexed residual RV volume. During the follow-up of 20.54±7.62 months, the functional class improved from 2.59±0.7 to 1.34±0.52 (P&lt;0.001). Conclusion: In Ebstein's anomaly, a higher TTA 'Z' score correlates with a lower postplication indexed residual RV volume. Hence, a complete trileaflet repair with offloading of RV by BCPS (when the TTA 'Z' score is &gt;2) is recommended. The short-term outcomes of our technique are promising.

title: Production of 'Valência' sweet orange on 41 rootstocks in the north of the state of São Paulo, Brazil

description: Abstract: The objective of this work was to select alternative rootstocks to 'Rangpur' lime for 'Valência' sweet orange scions in the northern region of the state of São Paulo, Brazil, based on initial fruit yield. Forty-one rootstocks were evaluated in an experiment carried out in March 2007, in the municipality of Colômbia, in the state of São Paulo. The accumulated fruit yield of 'Valência' sweet orange was assessed in the 2009, 2010, and 2011 crop seasons. The rootstocks 'Sunki' mandarin x Poncirus. trifoliata 'English', 'Malvasio SRA 115' mandarin, 'C-13' “S” citrange, 'Sunki' mandarin x P. trifoliata 'Benecke', 'Valência Rhode Red' sweet orange + 'Volkamer' lemon, 'C-54-4-4 SRA 337' mandarin, 'Cleopatra' mandarin x P. trifoliata 'Rubidoux', and 'À Peau Lisse SRA 267' have potential to replace 'Rangpur' lime in the northern region of the state of São Paulo, Brazil.

title: Effect of Weld Parameters on Residual Stress, Hardness and Microstructure of Dissimilar AA2024-T3 and AA7475-T761 Friction Stir Welded Joints

description: This study presents the effect of the welding parameters variation on the results of forces, temperature, residual stresses and Vickers micro hardness of dissimilar butt joints of AA2024-T3 and AA7475-T761 welded by friction stir welding (FSW). The tool rotational speed, feed rate and tool tilt angle were investigated using the Design of Experiments method. The obtained results of penetration force, temperature in the weld zone compared with the microscopic analysis of the microstructure showed that it is necessary a minimum amount of force and heat input to obtain a defect free weld zone. It was also notable that, friction stir welding has a wide stability range of its most significant parameters - rotational speed and feed rate - which grantee this minimum condition. Micro hardness’ profiles showed the effect of the grain size refinement towards the thermo-mechanically affected zone as well as, the effect of recrystallization inside the nugget. Residual stresses’ profiles showed a tensile stress peak at the shoulder contact area due the pressure with the base material on thermo-mechanically affected zone and the stress relief effect caused by high temperatures in the nugget resulting in a decrease in residual stress value. The most significant variables for residual stress results were rotational speed of the tool and welding feed rate, once their interaction rule the heat input in the weld zone.

title: Antiplatelet Therapy in Breast Cancer Patients Using Hormonal Therapy: Myths, Evidence and Potentialities – Systematic Review

description: Abstract Breast cancer is the most frequently diagnosed tumor in women worldwide, with a significant impact on morbidity and mortality. Chemotherapy and hormone therapy have significantly reduced mortality; however, the adverse effects are significant. Aspirin has been incorporated into clinical practice for over 100 years at a low cost, making it particularly attractive as a potential agent in breast cancer prevention and as an adjunct treatment to endocrine therapy in the prophylaxis of cardiovascular complications. The objective of this study was to evaluate the role of aspirin in reducing the incidence of breast cancer and to evaluate the impact of its use on morbidity and mortality and reduction of cardiovascular events as adjuvant therapy during breast cancer treatment with selective estrogen receptor modulators. A systematic review was performed using the PRISMA methodology and PICO criteria, based on the MEDLINE, EMBASE and LILACS databases. The original articles of clinical trials, cohort, case-control studies and meta-analyses published from January 1998 to June 2017, were considered. Most studies showed an association between the use of selective estrogen receptor modulators and the increase in thromboembolic events. The studies suggest a protective effect of aspirin for cardiovascular events during its concomitant use with selective estrogen receptor modulators and in the prevention of breast cancer. This systematic review suggests that aspirin therapy combines the benefit of protection against cardiovascular events with the potential reduction in breast cancer risk, and that the evaluation of the benefits of the interaction of endocrine therapy with aspirin should be further investigated.

title: Clinical and radiographic evaluation of dental implants in alveolar fissure area

description: Abstract Introduction The cleft lip and palate are malformations that cause important impacts not only aesthetic, auditory and phonetic, but also in the social integration of its bearer. Objective To evaluate the clinical and radiographic aspects of osteointegratable implants in a region of cleft lip and palate installed in a reference center in Salvador, Bahia. Material and method An observational study was carried out in which all the patients who performed osseointegrated dental implants in the area of alveolar fissure were enrolled between September 2014 and October 2016. After analyzing the records, implants were obtained that obtained secondary stability observed through bidigital locking at the time of the installation of the cicatrisers, as well as previous reconstruction with iliac crest graft, type of cleft, as well as complementary grafts performed in an outpatient setting and correlation of these with the success rate of the implants installed in that unit. Result Fifteen implants were installed in 10 patients with different types of fissures. The clinical success rate was 80% of the implants, and radiographically, in only one case there was suspicion of failure in the new bone formation. Conclusion Implants located in a region of fissure in the patients of the reference center in Salvador-Bahia presented clinically secondary stability and suggestive bone neoformation clinically and radiographically at levels similar to those described in the literature.

title: Rites, Rituals and Routine: Feminine Education in Catholic Confessional Schools in the Twentieth Century

description: ABSTRACT By sharing the process of formation of the new generations, the responsibility to teach other social codes to those who would become responsible for the maintenance and transformation of the dynamics of society was shared with educational institutions. Those institutions have commitments, such as offering technical and scientific knowledge based on principles validated by the society in which they are inserted. Brazilian society has belatedly shared with the school the task of training the new generations because of the "development model" adopted. Throughout the national history, access to formal education has only been considered a right recently, especially when it refers to the female portion of the population. Although full access was only achieved later, formal education in Brazil was available in a form, mainly in confessional schools (mostly catholic). In catholic schools during the twentieth century, in addition to the curricular content, there were diverse activities in the routine of the neophytes under their auspices to form character, and their sacred and intellectual conduct. Those activities delineated marks in the memories of those who experienced them or watched them sporadically. Using foundations of cultural history, we collected and analyzed fragments of memories (oral reports) and photographs of former students who attended the Saviniano schools (which taught only the feminine gender) until the 1970s, in Piauí, in order to analyze elements present in catholic schools and to demonstrate, from the school rituals, the constitution of school culture and its maintenance of along the life trajectory of the graduates.

title: Evaluation of dental needle deformation and fractal analysis

description: Abstract Introduction Needle fracture in dental anesthesia is rare, but its occurrence has serious complications and should be avoided. Objective The objective of this study was to evaluate the deformation of dental needles after the application of compression forces. Material and method Needles of the Dencojet and Septoject XL brands in the 27G and 30G gauges (4 groups) were folded in two opposite directions in a mechanical test machine DL200 - EMIC, based on ISO 7885: 2010. The compressive strength of the needles was measured at each fold. At the end, visual inspection was performed on an EK3ST magnifying glass in a magnification of 40× for analysis of needle integrity. Result 30G needles did not present significant differences between them. The largest gauges (27G) presented differences in the first (p = 0.0001) and in the second folding (p = 0.0016). Septoject XL 27G needles have been shown to be much less flexible, providing higher values of resistance to folding. Seventh percent of the Septoject XL 30G group fractured near the cannon. All samples from the Septoject XL 27G group showed fractures after the second fold. Conclusion All the gingival needles tested presented acceptable behavior, even when submitted to critical situations. Dencojet 27G needles have been shown to be more flexible when folded. All Septoject XL 27G needles fractured after the second fold. It is not advisable to bend the dental needles.

title: The Role of Quantitative Aortographic Assessment of Aortic Regurgitation by Videodensitometry in the Guidance of Transcatheter Aortic Valve Implantation

description: Abstract Background: Balloon post-dilatation (BPD) is often needed for optimizing transcatheter heart valve (THV) implantation, since paravalvular leak (PVL) after transcatheter aortic valve implantation is associated with poor outcome and mortality. Quantitative assessment of PVL severity before and after BPD is mandatory to properly assess PVL, thus improving implantation results and outcomes. Objective: To investigate a quantitative angiographic assessment of aortic regurgitation (AR) by videodensitometry before and after BPD. Methods: Videodensitometric-AR assessments (VD-AR) before and after BPD were analysed in 61 cases. Results: VD-AR decreased significantly from 24.0[18.0-30.5]% to 12.0[5.5-19.0]% (p &lt; 0.001, a two-tailed p &lt; 0.05 defined the statistical significance). The relative delta of VD-AR after BPD ranged from -100% (improvement) to +40% (deterioration) and its median value was -46.2%. The frequency of improvement, no change, and deterioration were 70% (n = 43), 25% (n = 15) and 5% (n = 3), respectively. Significant AR (VD-AR &gt; 17%) was observed in 47 patients (77%) before and in 19 patients (31%) after BPD. Conclusions: VD-AR after THV implantation provides a quantitative assessment of post-TAVI regurgitation and can help in the decision-making process on performing BPD and in determining its efficacy.

title: Electronic government services in Brazil: an analysis based on measures of access and users’ internet skills

description: Abstract This article aims to analyze how measures to promote Internet access, and users’ competencies influence the use of electronic government services in Brazil. We adopted Sen’s Capability Approach as theoretical framework in order to analyze the microdata from the ICT Households 2013, a national-wide survey coordinated by the Regional Center for Studies on Development of the Information Society (Cetic.br). The results indicate that for social classes C (middle class), D and E (lower class) the increase in the odds ratio of the use of e-gov services is strongly influenced by both internet access preferably at home or work (individual access) as well as the users’ internet skills.
