title: Body mass index and acoustic voice parameters: is there a relationship?,

description: Abstract Introduction Specific elements such as weight and body volume can interfere in voice production and consequently in its acoustic parameters, which is why it is important for the clinician to be aware of these relationships. Objective To investigate the relationship between body mass index and the average acoustic voice parameters. Methods Observational, cross-sectional descriptive study. The sample consisted of 84 women, aged between 18 and 40 years, an average of 26.83 (±6.88). The subjects were grouped according to body mass index: 19 underweight; 23 normal ranges, 20 overweight and 22 obese and evaluated the fundamental frequency of the sustained vowel [a] and the maximum phonation time of the vowels [a], [i], [u], using PRAAT software. The data were submitted to the Kruskal-Wallis test to verify if there were differences between the groups regarding the study variables. All variables showed statistically significant results and were subjected to non-parametric test Mann-Whitney. Results Regarding to the average of the fundamental frequency, there was statistically significant difference between groups with underweight and overweight and obese; normal range and overweight and obese. The average maximum phonation time revealed statistically significant difference between underweight and obese individuals; normal range and obese; overweight and obese. Conclusion Body mass index influenced the average fundamental frequency of overweight and obese individuals evaluated in this study. Obesity influenced in reducing maximum phonation time average.

title: Short term histopathological effects of GaAlAs laser on experimentally induced TMJ osteoarthritis in rabbits

description: Abstract The aim of this study was to evaluate the biostimulation (BS) effect of the gallium-aluminum-arsenide (GaAlAs) diode laser by histopathology with an experimental osteoarthritis (OA) model in the temporomandibular joints (TMJ) of rabbits, in the early period. GaAlAs diode laser is used for pain reduction in TMJ disorders. Twenty-four adult male New Zealand white rabbits were randomly divided into three equal groups: Control Group (CG), Study Group 1 (SG-1), and Study Group 2 (SG-2). Mono-iodoacetate (MIA) was administered to the right TMJs of all rabbits. The rabbits did not undergo any treatment for four weeks to allow the development of osteoarthritis. In SG-1, laser BS was applied to the rabbits at 940 nm, 5 W, and 15 J/cm2 in continuous wave mode at 48-hour intervals for 14 sessions; and in SG-2, laser BS was applied with the same parameters at 24-hour intervals for 28 sessions. Laser BS was not applied to the rabbits in CG. All rabbits were sacrificed simultaneously. The TMJ cartilage, osteochondral junction, chondrocyte appearance, and subchondral ossification were evaluated histopathologically. There was no statistically significant difference between the groups in terms of cartilage, osteochondral junction, chondrocyte appearance, and subchondral ossification values (p &gt; 0.05). The laser BS protocol used in the study had no positive histopathological effects on TMJ OA in the early period.

title: PERCEPTIONS ON THE IMPORTANCE OF VACCINATION AND VACCINE REFUSAL IN A MEDICAL SCHOOL

description: ABSTRACT Objective: To identify the perception of medical students and physicians on the importance of vaccination and the risks of vaccine refusal. Methods: Cross-sectional study with application of questionnaires about vaccines, vaccine refusal and its repercussions on public and individual health. A sample of 92 subjects was selected from a private medical school: group 1 (53 students from first to fourth grades) and group 2 (39 physicians). Data collected were tabulated in the Microsoft Excel Program and analyzed by Fisher’s exact test. Results: Both groups considered the National Immunization Program reliable and recognized the importance of vaccines, but 64.2% of students and 38.5% of physicians are unaware of the vaccine-preventable infectious diseases in the basic immunization schedule. Most of the interviewees had a personal vaccine registry, but not all had received the 2015 influenza vaccine. Both groups had known people who refused vaccines for themselves or for their children (respectively, 54.7 and 43.3% of students and 59.0 and 41.0% of physicians). The total of 48.7% of physicians had already assisted vaccine refusers. Appointed causes of vaccine refusal were: fear of adverse events, philosophical and religious reasons and lack of knowledge about severity and frequency of diseases. Ethical aspects of vaccine refusal and legal possibilities of vaccine requirements for children are not consensus. Conclusions: Medical students and doctors are not adequately vaccinated and have queries about the vaccination schedule, vaccine safety and vaccine refusal. Improving these professionals’ knowledge is an important strategy to maintain vaccine coverage and address vaccine refusal ethically.

title: A novel ultrasonic tip for removal of filling material in flattened/oval-shaped root canals: a microCT study

description: Abstract The aim of this study was to evaluate the influence of a novel ultrasonic tip as an auxiliary method for removing filling material from flattened/oval-shaped canals. The null hypothesis tested was that this method does not influence removing the filling material in flattened/oval-shaped canals. Forty-five mandibular incisors were selected and randomly divided into three experimental groups (n = 15) according to different protocols for removing root canal filling material. Group R: Reciproc R25/.08, Group RC: Reciproc R25/.08 + Clearsonic tip, and Group CR: Clearsonic tip + Reciproc R25/.08. The teeth were scanned pre and post-operatively by means of a micro-computed tomography system. Data were analyzed using non-parametric Kruskal-Wallis and Dunn tests (p &lt; 0.05). The percentage of residual root canal filling material between the experimental groups was examined. Statistically significant differences between the experimental groups were found in the root canal. Group R had the highest percentage of residual root canal filling material when compared with Groups RC and CR. The lowest percentage of residual root canal filling material was observed in Group CR. In the apical third of the root canal, statistically significant differences were found between the different protocols. The use of the ClearSonic tip followed by the Reciproc 25/.08 file to remove filling material resulted in the lowest percentage of residuals in the whole root canal and in the apical third.

title: EVALUATION OF NUTRITIONAL STATUS IN PATIENTS WITH CYSTIC FIBROSIS ACCORDING TO AGE GROUP

description: ABSTRACT Objective: To evaluate the nutritional profile of the population assisted at a reference center for cystic fibrosis treatment. Methods: Cross-sectional study including patients with cystic fibrosis assisted at a pediatric reference center in São Paulo, Brazil, in 2014. All patients attending regular visits who agreed to participate in the study were included. A questionnaire on dietary habits (24-hour diet recall) and socioeconomic characteristics was applied. Anthropometric data (compared with the reference from the World Health Organization, 2006 and 2007) and pulmonary function data were collected from medical records. Patients were stratified into age groups for statistical analysis. Results: A total of 101 patients were included in the study (59.4% male, 86.4% Caucasian), with median age of 10 years old. Most patients (n=77; 75%) were classified as eutrophic, but lower values of body mass index (BMI) Z scores were observed in schoolchildren and adolescents. The proportion of underweight patients was 10% (n=2) among preschoolers and 35% (n=6) of the school age group. Dietary intake was adequate, and the use of only two supplements (medium chain triglycerides and complete powdered supplement) was associated with adequacy of macronutrient intake. The socioeconomic characteristics did not show any statistical association with the nutritional state or nutritional consumption. Lung function was not significantly different between neither adolescents nor individuals with worse nutritional status in this sample. Conclusions: Most of the patients presented adequate nutritional status and adequate consumption of calories and macronutrients, indicating appropriate nutritional management. New studies focusing on preschool children should be performed to assess if it is possible to reduce the nutritional risk of patients with cystic fibrosis at older ages.

title: What are the effects of population aging on pension systems of Brazil, Spain and France?

description: Abstract The aim of this study is to analyze the impacts of population aging on pay-as-you-go pension schemes in three countries: Brazil, Spain and France. Benefits and contributions are calculated based on current rules and population projections by sex and age group, up until 2100. From 2016 to 2100, the number of old-age benefits in the three countries is expected to increase by 235%, 54% and 73%. By 2050, ceteris paribus, the Brazilian deficit will amount to USD 188 billion, reaching USD 260 billion in 2100. For France and Spain figures will be USD 134 billion and USD 92 billion. In 2100, the Spanish per capita deficit will be the highest: USD 7,200, against USD 5,400 (France) and USD 3300 (Brazil). Two additional exercises are included. The first is the calculation of the Necessary Contribution Rate. By 2016 Brazil’s rate should already be at 40%. For the other countries, the rates should be 23% (France) and 32% (Spain). In 2050, unless some action is taken, the Brazilian rate will surpass an absurd 100%, and by 2100, an unreal 160%. The second exercise was the calculation of the Average Balance Benefit. For Spain, there would be a reduction of USD 884 per month to USD 372 by 2050. For Brazil, the current balance benefit of USD 248 would be reduced, by 2050, to USD 98. Reduction in Brazil (60%) is almost the same as in Spain (58%). The results provide evidence of the need for pension reforms due to aging.

title: Human errors in emergency situations: cognitive analysis of the behavior of the pilots in the Air France 447 flight disaster

description: Abstract On June 1st 2009, the Airbus 330 of Air France that left from Rio de Janeiro to Paris, falls into the Atlantic Ocean killing 228 people on board. One of the causes of the accident mentioned by official agencies were the mistakes made by the pilots, which combined with technical failures led to the loss of control of the plane. Human error was again appointed as the last link in the chain of events leading to the accident and, therefore, as its immediate cause. In this paper it is proposed an alternative explanation, which is not limited to the identification of mistakes made by the crew but proposes an explanation of mistakes. In a cognitive analysis of accidents based on the concept of action and situated cognition, the error is not the point of arrival of the diagnosis of the causes of an accident, but it is its starting point. Like this, resumed the official results of the accident, the specific reference to the expected behavior of pilots in relation to evolving unforeseen and breach of aviation rules during the four minutes leading up to the fall of the aircraft in the ocean. This critical analysis makes room for a more comprehensive explanation of the pilots behavior, based on another frame of reference - the cognitive analysis of accidents - not yet incorporated in the official models of analysis of human factors in safety, and allows to speculate on other actions for prevention.
