title: Fracture resistance of abutment screws made of titanium, polyetheretherketone, and carbon fiber-reinforced polyetheretherketone

description: Fractured abutment screws may be replaced; however, sometimes, the screw cannot be removed and the entire implant must be surgically removed and replaced. The aim of this study was to compare the fracture resistance of abutment retention screws made of titanium, polyetheretherketone (PEEK) and 30% carbon fiber-reinforced PEEK, using an external hexagonal implant/UCLA-type abutment interface assembly. UCLA-type abutments were fixed to implants using titanium screws (Group 1), polyetheretherketone (PEEK) screws (Group 2), and 30% carbon fiber-reinforced PEEK screws (Group 3). The assemblies were placed on a stainless steel holding apparatus to allow for loading at 45o off-axis, in a universal testing machine. A 200 N load (static load) was applied at the central point of the abutment extremity, at a crosshead speed of 5 mm/minute, until failure. Data was analyzed by ANOVA and Tukey’s range test. The titanium screws had higher fracture resistance, compared with PEEK and 30% carbon fiber-reinforced PEEK screws (p &lt; 0.05). In contrast, no statistically significant difference was observed between the fracture resistance of the PEEK and the 30% carbon fiber-reinforced PEEK screws (p&gt; 0.05). Finally, visual analysis of the fractions revealed that 100% of them occurred at the neck of the abutment screw, suggesting that this is the weakest point of this unit. PEEK abutment screws have lower fracture resistance, in comparison with titanium abutment screws.

title: Prevalence and factors associated with surfactant use in Brazilian Neonatal Intensive Care Units: A multilevel analysis

description: Abstract The treatment with exogenous surfactant reduces mortality and the risk of complications in preterm newborns with Respiratory Distress Syndrome. Higher usage levels have been associated with individual and institutional factors. The study aimed to identify these factors associated with use of this technology in 16 public Brazilian Neonatal Units using logistic multilevel analysis. In a sample of 630 newborns the use at some time was 82.6%. Only 24.7% made use of this technology up to two hours after birth. An intraclass correlation of 0.30 showed that 30% of the variance in the use of exogenous surfactant could be assigned to the contextual level. In the final model, a greater severity score (SNAPPE-II) was associated with increased surfactant use (OR = 2.64), whereas being small for gestational age (SGA) (OR = 0.59) was associated with lower use of this technology. At the contextual level the number of beds in the unit &gt;15 (OR = 5.86), units with higher complexity (OR = 1.73) or units with implemented Kangaroo Mother Care (OR = 2.91), especially units in Rio de Janeiro state (OR = 16.17) were associated with greater surfactant use. Although individual clinical features explained most of the variation in the use of this technology, factors linked to the institution were also of utmost importance.

title: Vaccine confidence and hesitancy in Brazil

description: Despite the overall benefits of immunization, vaccine hesitancy has been a growing trend and has been associated with the resurgence of vaccine-preventable diseases. The aim of this study was to assess vaccine confidence and hesitancy in Brazil, as part of a wider project to map vaccine confidence globally. One thousand subjects were interviewed, either online or face-to-face, based on a general questionnaire regarding perceptions on vaccines and vaccination. Further exploratory questions were used with the subset of respondents who were parents of children aged under 5. Such questions extracted information regarding vaccination behavior, opinions on vaccination and government health services, and vaccine hesitancy. Reasons for hesitancy were classified as relating to confidence, convenience and/or complacency, and the population was also analyzed socio-demographically. The results showed that overall confidence in immunization was higher than confidence in family planning services, community health workers and emergency services. Seventy-six people reported hesitancy to vaccinate. The commonest reasons for hesitancy were issues with confidence (41.4%), efficacy/safety of the vaccine (25.5%) and concerns about adverse events (23.6%). The sociodemographic analysis revealed that vaccine hesitancy was associated with marital status, level of education and income. Despite overall vaccine confidence being high, a clear trend toward lower levels of confidence was associated with higher levels of hesitancy, which warrants on-going monitoring, due to the dynamic and changing nature of vaccine hesitancy.

title: Does the light source affect the repairability of composite resins?

description: The aim of this study was to examine the effect of the light source on the microshear bond strength of different composite resins repaired with the same substrate. Thirty cylindrical specimens of each composite resin—Filtek Silorane, Filtek Z550 (3M ESPE), Gradia Direct Anterior (GC), and Aelite Posterior (BISCO)—were prepared and light-cured with a QTH light curing unit (LCU). The specimens were aged by thermal cycling and divided into three subgroups according to the light source used—QTH, LED, or PAC (n = 10). They were repaired with the same substrate and a Clearfil Repair Kit (Kuraray). The specimens were light-cured and aged for 1 week in distilled water at 37 °C. The microshear bond strength and failure modes were assessed. There was no significant difference in the microshear bond strength values among the composite resins, except for the Filtek Silorane group that showed significantly lower bond strength values when polymerized with the PAC unit compared to the QTH or LED unit. In conclusion, previously placed dimethacrylate-based composites can be repaired with different light sources; however, if the composite to be repaired is silorane-based, then using a QTH or LED device may be the best option.

title: A proposal for the creation of a system to monitor cases of malignant mesothelioma in Curitiba, Paraná, Brazil

description: The study proposes the creation of a system to monitor cases of malignant mesothelioma in the municipality of Curitiba, Paraná State, Brazil, based on the Italian model. This diagnosis-type action-research project featured exploratory and planning phases conducted from July 2015 to May 2017. The following search tools were used: Hospital-Based Cancer Registries Integrator with specific morphologies for mesothelioma; Hospital-Based Cancer Registry with codes C38.4 and C45 of the International Classification of Diseases, 10th revision, and/or records coded by the ICD-O with topographies C38 and C48; Population-Based Cancer Registry of the Curitiba Municipal Health Department, with the same codes. The study also identified, analyzed, and adapted to the Brazilian reality the model, questionnaires, and registry software for mesothelioma from Lombardy, Italy. Fifteen cases of mesothelioma were recorded in the Hospital-Based Cancer Registries Integrator. Two cases were recorded in the University Hospital-Based Cancer Registry and 16 in the Cancer Hospital. There were 317 cases recorded in the Population-Based Cancer Registry during the same period. Although some information was complete, data were lacking on patients’ occupational history, thereby preventing the determination of a causal nexus. Given a predicted increase in cases of mesothelioma in the coming decades and the response to court cases, the implementation of registries has become essential to facilitate knowledge and follow-up on the determination of the causal link and specific sources of asbestos exposure in the country.

title: Sleep bruxism and anxiety level in children

description: This study evaluated the association of level of anxiety in children with and without sleep bruxism (SB). The study was performed with 84 six- to eigth-years-old children, divided into two groups: with bruxism (BG) and without bruxism (CG). Following the criteria purposed by American Academy of Sleep Medicine (AASM) to determine SB, the presence of tooth wear has been verified through clinical examinations, and the parents have answered a questionnaire about their children’s behavior and habits. Additionally, the State-Trait Anxiety Inventory for Children (STAIC) was applied to parents of the selected patients. Data analysis revealed a statistical significant difference between the groups (Student’s t-test, p= 0.0136). Based on the results, anxiety assessment revealed that children with bruxism have reached higher levels in the STAIC scale than the non-bruxism group. Therefore, it indicates a direct relationship between the presence of anxiety disorder and the onset of bruxism in children.

title: A practical approach to the teaching of electromagnetism using low cost induction motor

description: Abstract The paper describes the development and construction of a low-cost three-phase induction open motor for the teaching of electromagnetism in the disciplines of physics and electrical machines of the technical courses. Voltage stabilizer scrap materials were used in the construction of the prototype. Today's computers have built-in power supplies with advanced technology that eliminates the use of voltage stabilizer modules. As results, many of these modules are no longer used, becoming scrap and generating disposal problems for the environment. The motor was implemented and works satisfactorily for the intended purpose. The prototype is used in the practical classes of electromagnetism and electric machines of the technical level courses in electrotechnology and technology in industrial automation. In these classes several phenomena of electromagnetism related with the induction motor are discussed.

title: Looking to the blue sky with colored patterns

description: Abstract This work presents a simple alternative technique to observe the polarization of the skylight on Earth. Using a birefringent material and a polarizer to look at the polarized light from the blue sky, it is possible to see a colored pattern that is associated to the birefringence of the material and the polarized light. Three different ways to polarize the light are also discussed in the context of the proposed experiment.

title: Mortality by road traffic accidents in adolescents and young people, Brazil, 1996-2015: will we achieve SDG 3.6?

description: Abstract This paper aims to analyze the main characteristics of Road Traffic Accidents (RTA) mortality in Brazil for the period 1996-2015, focusing on the 10-29 years’ age group. This is a two-step study consisting of (i) a bibliographic review on the topic of traffic violence in Brazil, and (ii) a study on RTA mortality in the Mortality Information System (SIM). The former situates the state of the art of scientific production on the theme and produces the theoretical reference for the analysis of the latter. During the period, about 39,000 people died by RTA, of which about 13,200 adolescents and young people died. The country should curb mortality to somewhere around 19,500/year and, among adolescents and young people, to 6,500/year to achieve SDG 3.6. With the establishment of the Brazilian Traffic Code (CTB), RTA mortality rate fell between 1997 and 2000. The rate increased in the subsequent decade. The focus on adolescents and young people help us understand that, in the post-CTB and Prohibition, male black and brown motorcyclists became the main victims. The literature provides data analysis and shows that reduction is currently submitted to an articulated discussion that involves worker’s health, gender, employment, urban mobility and advertising policies. Concerning SDG, this means that achieving SDG 3.6 is a process that involves interacting with policies targeting other SDGs.

title: Young population, sexually-transmitted diseases and rights. National and regional scenario in Argentina

description: Abstract In the context of social and demographic studies of sexual and reproductive health, this paper discusses the situation of young people in Argentina, emphasizing the problems revolving around Sexually Transmitted Diseases (STDs) and the compliance with sexual rights. This work aims to study the calendars and characteristics of the onset of sexual life in young Argentinean people and to describe the current situation of knowledge, practices, and access related to sexual life. Based on data from the National Survey on Sexual and Reproductive Health ( 2013) we worked with the universe of young people between 15 and 29 years of age (n = 2,084 women, n = 1,872 men, without weighting) and analyzed the differences in the calendars of the onset of sexual life, as well as the knowledge and prevention of STDs by gender sex, age groups, household income and geographical regions.A national scenario was found featuring marked tendencies in the calendars of first sexual intercourse by gender sex, as well as in the knowledge about STDs. However, the analysis by region and household income in each gendersex showed high heterogeneities, which would indicate certain limitations in the access to sexual education and the effective compliance of people’s rights, as well as an increased risk to contracting STDs in specific social groups.
