title: Evaluation of two amoxicillin protocols for antibiotic prophylaxis in implant placement surgeries

description: ABSTRACT Objective The aim of this study was to evaluate the effectiveness of two amoxicillin protocols for antibiotic prophylaxis in implant placement surgeries. Methods A clinical study was performed with 66 volunteers of both genders (mean 51,9 ± 2,5 years) that met the inclusion criteria and were randomly assigned into 2 groups: Group 1 (n=35) - oral administration of amoxicillin (2g) 1 hour before the surgical procedure and Group 2 (n=31) oral administration of amoxicillin (2g) 1 hour before the surgical procedure and 500mg every 8 hours during 7 days after the surgeries. The following clinical parameters were evaluated: adverse reactions, pain and implants failure. The pain was evaluated in the surgery day (before, immediately after and at night), 24h, 48h, 72h and one week after the surgery and other clinical parameters were evaluated in daily appointments until the third postoperative day, 7 days and three months after the surgeries. Data were analyzed and statistical significance was 5%. Results Adverse reactions (headache, diarrhea, stomachache and nauseas) and implant failure occurred only in G2 (4 volunteers and 3 implants, respectively). Regarding pain, higher values for G2 on “at the night (p=0.0043), 24h (p=0.0013), 48h (p=0.0187) e 72h (p=0.0445) were observed. Conclusion The present study showed that a single dose of amoxicillin was effective in antibiotic prophylaxis in implant placement surgeries, suggesting that the use of amoxicillin in the postoperative period did not bring additional benefit.

title: Performance of calves receiving probiotic containing “Bacillus subtilis” and “Bacillus licheniformis”

description: SUMMARY Twenty-four Holstein calves were utilized and received 4L/d of liquid diet consisting of commercial milk replacer, and had free access to water and starter concentrate. Weaning occurred at the 8th week of age. Animals were distributed in a randomized block design, in the following treatments: 1) Control - without supplementation with probiotic, 2) Supplementation: 2g/d of Bacillus subtilis and Bacillus licheniformis, via milk replacer. Every week calves were weighted and body measurements were taken. Blood samples were drawn weekly for determination of hematocrit, glucose, total protein, urea and albumin. Fecal samples were weekly collected for lactic acid bacteria, enterobacteria couting and fecal pH determination. Concentrate starter intake and fecal scores were monitored daily. Body weight, average daily gain, and corporal measurements were not affected by the supplementation of probiotic; however, presented a significant age effect. The fecal score, fecal pH and starter intake were not affected by probiotic supplementation. However, starter intake and fecal pH were affected by age due to calves’ natural growth. The acid lactic bacteria count was higher than the count of enterobacteria during the whole evaluation period. Only enterobacteria were affected by the age of animals, while acid lactic bacteria remained constant despite little variations. Blood parameters were also not affect by supplementation of probiotic, but all of them, except albumin concentrations, were influenced by age. The supplementation with probiotic containing Bacillus subtilis and Bacillus licheniformis via milk replacer presented no benefits in dairy calves performance or metabolism and did not reduced the occurrence of diarrhea.

title: Comminution circuits for compact itabirites

description: Abstract In the beneficiation of compact Itabirites, crushing and grinding account for major operational and capital costs. As such, the study and development of comminution circuits have a fundamental importance for feasibility and optimization of compact Itabirite beneficiation. This work makes a comparison between comminution circuits for compact Itabirites from the Iron Quadrangle. The circuits developed are: a crushing and ball mill circuit (CB), a SAG mill and ball mill circuit (SAB) and a single stage SAG mill circuit (SSSAG). For the SAB circuit, the use of pebble crushing is analyzed (SABC). An industrial circuit for 25 million tons of run of mine was developed for each route from tests on a pilot scale (grinding) and industrial scale. The energy consumption obtained for grinding in the pilot tests was compared with that reported by Donda and Bond. The SSSAG route had the lowest energy consumption, 11.8kWh/t and the SAB route had the highest energy consumption, 15.8kWh/t. The CB and SABC routes had a similar energy consumption of 14.4 kWh/t and 14.5 kWh/t respectively.

title: Configuration Study of Structurally Integrated Thermal Protection Systems for a Sub-Orbital Platform

description: ABSTRACT: The atmospheric hypersonic flight of sub-orbital and space vehicles generates aerodynamic heating and high wall heat fluxes, inducing high temperatures on the vehicle's structures and affecting their mechanical behavior, besides degrading the operation of board equipment. Furthermore, since payload preservation is always mandatory, the use of efficient Thermal Protection Systems (TPS) is a key-requirement for any spacecraft design. As an outcome, designing the TPS is a critical aspect of any rocket development program, since an undersized system may result in catastrophic failure, and an oversized one implies increased mass and cost. Sub-orbital platforms are a low-cost alternative for microgravity research. A sub-orbital platform (SARA) is being developed by Instituto de Aeronáutica e Espaço (IAE) for such an application, and its current design uses a conventional layer of cork as TPS to protect its lateral surface, with the trade-off of large mass. Alternatively, a Thermally Integrated Structural Sandwich Core (TISSC), which consists of a structural sandwich panel in a three-layer plate with two face sheets and the core, presents advantages such as lightweight, low maintenance, insulation as well as load bearing capabilities, and low life-cycle cost. In this work, a TISSC is proposed to replace SARA's current TPS. The main contribution of the presented methodology is to couple the aerodynamic heating, heat transfer in porous insulation and thermo-structural analyses of the proposed configuration in order to evaluate the TISSC TPS performance. The results are compared with those obtained for the current SARA TPS design, showing improvements in thermal insulation and structural strength, as well as a remarkable mass reduction.

title: THE SCIENTIFIC CINEMA IN ARGENTINA AT THE BEGINNING OF THE 20TH CENTURY: BETWEEN EDUCATION AND ENTERTAINMENT

description: AbstractThe first scientific Argentine films were custom-made products shot by the same production companies, and with the same formal, thematic and market strategies that those of commercial cinema. Thus, far from being a material accesible only to specialists, these films were often exhibited in movie theatres, promoted in magazines and newspapers of the time and some of them even became bockbusters. From the analysis of some of the most relevant films on the subject, we will show that just as cinema became an integral part of the medical-scientific world of the time, so too science became an important component of the entertainment industry from the very same origins of the medium.

title: Association between diabetes and causes of dementia: Evidence from a clinicopathological study

description: ABSTRACT. Background: Diabetes mellitus is a risk factor for dementia, especially for vascular dementia (VaD), but there is no consensus on diabetes as a risk factor for Alzheimer's disease (AD) and other causes of dementia. Objective: To explore the association between diabetes and the neuropathological etiology of dementia in a large autopsy study. Methods: Data were collected from the participants of the Brain Bank of the Brazilian Aging Brain Study Group between 2004 and 2015. Diagnosis of diabetes was reported by the deceased's next-of-kin. Clinical dementia was established when CDR ≥ 1 and IQCODE &gt; 3.41. Dementia etiology was determined by neuropathological examination using immunohistochemistry. The association of diabetes with odds of dementia was investigated using multivariate logistic regression. Results: We included 1,037 subjects and diabetes was present in 279 participants (27%). The prevalence of dementia diagnosis was similar in diabetics (29%) and non-diabetics (27%). We found no association between diabetes and dementia (OR = 1.22; 95%CI = 0.81-1.82; p = 0.34) on the multivariate analysis. AD was the main cause of dementia in both groups, while VaD was the second-most-frequent cause in diabetics. Other mixed dementia was the second-most-common cause of dementia and more frequent among non-diabetics (p = 0.03). Conclusion: Diabetes was not associated with dementia in this large clinicopathological study.

title: Legal proceedings to obtain medicines in Ribeirão Preto

description: Abstract This study aims to characterize lawsuits pleading for medicines in Ribeirão Preto, São Paulo, Brazil. A descriptive and cross-sectional study was carried out, which included all such judicial processes in the municipality between January 1999 and June 2014. Most of the time, public agents were responsible for legal representation (81.8% of cases), most of the prescriptions came from the private system (50.10%), and only 3% of prescribers concentrated nearly 30% of the cases. Diabetes and attention deficit hyperactivity disorder were the most prevalent diseases; with analogous insulins and methylphenidate being the most required drugs. It is concluded that, on average, 30% of the city’s budget for the purchase of medicines is spent on medicines obtained through the courts. Approval CEP-FCFRP/USP 2.598.720

title: VISUAL SEARCH AND DECISION-MAKING OF VOLLEYBALL COACHES

description: ABSTRACT The research aimed at comparing the decision making of volleyball coaches through visual search strategies (number and duration of visual fixations) based on their years of experience. The sample consisted of thirty-four volleyball coaches (n = 34) with a mean age of 32.5 ± 9.4 years. Thus, two groups were formed: beginners (2.8 ± 1.9 years of practice) and experienced (19 ± 7.2 years of practice). To assess the tactical knowledge related to aspects of decision-making, the coaches conducted the analysis of the end-attack scenes of the Declarative Tactical Knowledge Test in Volleyball. The results not related significant differences to the visual strategies, decision-making and declarative tactical knowledge in the analysis of the scenes between the two groups (p&gt; 0.05), and the power of the effect ranged from small to moderate for the analyzed variables. In this context, it was noticed that the visual strategies used between the coaches with different times of experience were similar.

title: Standard obesogenic diet: the impact on oral health in children and teenagers at the Recôncavo Baiano - Brazil

description: AbstractThe aim of this study is to evaluate the influence of dietary patterns on the occurrence of dental caries. Using a population-based, cross-sectional study design, we assessed a sample of 1.439 children aged 6-13 years who were enrolled in public schools in the municipality of São Francisco do Conde, Bahia state, Brazil. Oral examinations for dental caries were performed by two dental surgeons (Kappa = 0.72) in the school environment under natural light with the aid of a wooden spatula and gauze. Dietary intake was assessed using the qualitative-quantitative food frequency questionnaire. A questionnaire on the demographic and socioeconomic conditions was applied to the families. The Poisson multivariate analysis was performed for statistical purposes. Considering both dentitions, the prevalence of caries was 82.14% and 37.3% in the permanent and deciduous dentitions, respectively. The identified dietary patterns were classified into “standard obesogenic" and "prudent." The results showed statistically significant association between the obesogenic dietary pattern and dental caries; the proportion of students with dental caries was 1.4 times higher among those who most frequently consumed foods that constitute a standard obesogenic diet (PR = 1.40, 95% CI: 1.04-1.96) compared to those who less frequently consumed these types of foods. A positive association between the obesogenic dietary pattern and dental caries was found in the students investigated. Therefore, the promotion of healthy eating habits and nutritional habits should be encouraged to prevent dental caries in children and adolescents.
