title: Spontaneous rupture of superficial femoral artery aneurysm: case report

description: Abstract Isolated true aneurysms of the superficial femoral artery (SFA) are rare, accounting for 0.5% of peripheral aneurysms. The literature up to 2012 contains reports of just 103 patients with isolated SFA aneurysms. The main complications are thrombosis, distal embolization, and rupture, which is the most common of the three. The authors report the case of a 55-year-old male patient admitted to the emergency service with pain and a pulsatile mass in the left thigh, subsequently confirmed as rupture of an SFA aneurysm. The patient underwent open aneurysm repair with ligature and revascularization with a reversed saphenous vein bypass.

title: Consistency in the declaration of assets of candidates in the brazilian elections: fiction or reality?

description: Abstract Candidates data in the Brazilian elections of 2010, 2012 and 2014 were compared with information regarding the population in general. A total of 486,832 applications were analyzed. The candidates presented higher age and level of schooling than the Brazilian population in general. As previous research positively correlates age and level of schooling with assets, it can be assumed that the candidates would have greater assets, on average, than the general population. The study showed that candidates had more residencies and vehicles than the general population. However, the percentage of candidates who had bank assets was very low compared to the population. The results point out that a portion of the candidates’ assets is not correctly declared, which creates a serious problem in the principal-agent relationship.

title: Use of FTIR-ATR Spectroscopy Combined with Multivariate Analysis as a Screening Tool to Identify Adulterants in Raw Milk

description: The objective of this study was to use Fourier transform infrared (FTIR) spectroscopy combined with multivariate analysis to identify adulterations in raw milk and in samples from producers. Five levels of concentration of sodium bicarbonate, sodium hydroxide, hydrogen peroxide, starch, sucrose and urea were used. A total of 620 samples previously adulterated, frozen and lyophilized were analyzed in FTIR-attenuated total reflection (ATR) equipment and 15 peaks of the spectra were obtained. With the multiple linear regression method for samples adulterated with sodium bicarbonate, sucrose and urea, a coefficient greater than 75% was obtained, and with artificial neural networks all adulterated samples obtained a percentage of correctness greater than 76.6%, making it possible to identify adulterants from 0.1%. Of the 249 samples of producers analyzed, 2.4% were adulterated. With the use of FTIR allied to the multivariate analysis as a screening method, it was possible to obtain a satisfactory classification for the adulterated samples in this study.

title: Deracemization of sec-Alcohols through Sequential Application of C. albicans and Ketoreductases

description: A biocatalytic cascade process was developed using immobilized cells of the wild type yeast Candida albicans CCT 0776 in calcium alginate beads and a commercially available ketoreductase. The aim was to promote deracemization by stereoinversion of (±)-1-arylethanols in high substrate concentration (above 100 mmol L-1) to prepare the (R)-enantiomers of the alcohols (90-99%), with a high enantiomeric excess (83-99%) after 2 to 19 h. The (R)-1-(3-methoxyphenyl)ethanol, with 70% yield and 91% ee, obtained after 5 h was used to prepare (S)-1-(3-methoxyphenyl)-ethylamine with 60% yield and 91% ee after two steps, a key intermediate in the synthesis of (S)-rivastigmine.

title: IMPACT OF THE APPENDICEAL POSITION ON THE DIAGNOSIS AND TREATMENT OF PEDIATRIC APPENDICITIS

description: ABSTRACT Objective: To investigate how symptoms vary according to the appendiceal position in pediatric patients and to demonstrate that the laparoscopic approach is safe and effective in any appendiceal location by comparing each location to another. Methods: The medical records of 1,736 children aged 14 or younger who underwent laparoscopic appendectomy over a period of 14 years were analyzed retrospectively. Patients were divided according to the position of the appendiceal tip into four groups: anterior, pelvic, retrocecal and subhepatic. The Kruskal-Wallis and chi-square tests were used with the Bonferroni correction, with a significant p&lt;0.05. Results: The appendiceal location was anterior in 1,366 cases, retrocecal in 248 cases, pelvic in 66 cases and subhepatic in 56 cases. There were no significant differences between the groups in terms of patient age and gender. Abdominal pain was the only symptom with statistically significant differences between the groups. The rate of perforated appendicitis was higher in the subhepatic and pelvic positions. Intraoperative complications and conversions were not statistically significant. Technical difficulties and operative time were higher in subhepatic position. The rate of postoperative complications was similar between the different locations, except for bowel obstruction, which was higher in pelvic appendicitis. Conclusions: The clinical symptoms of appendicitis hardly ever change with the position of the appendix. The laparoscopic approach is safe and effective, regardless the appendiceal location.

title: Volatile compounds and quality analysis in commercial medicinal plants of Camellia sinensis

description: ABSTRACT: The interest in the use of green tea (Camellia sinensis) (L.) Kuntze (Theaceae) products have increased in the last few years due to its medicinal properties. In the present study, we proposed that headspace solid phase microextraction, in combination with gas chromatography coupled to mass spectrometric could be an efficient method to assess the volatile compounds and to ensure the quality control of C. sinensis. We have also compared the anatomical leaf of different commercial green tea samples, analyzed the information in their labels and determined the presence of foreign materials, moisture content, total ashes and microorganisms. Among the 30 analyzed samples, six were identified as C. sinensis according to the anatomical study; 83.4% were not in accordance with the specified limits for foreign matter and 6.6% for moisture content. All samples presented total ashes in accordance with the current legislation. The analysis indicated the presence of several different volatile organic compounds, being terpenes, hydrocarbons and alcohols the major ones. Microbiological analysis showed that 13.3% and 16.6% of the samples exceeded the limits for counts of molds and yeasts, and for mesophilic bacteria, respectively. 73.3% presented E. coli above the established sanitary limits.

title: Black Carbon Associated to PM1.0 and PM2.5: Mass Variation due to Combustion of Biodiesel/Diesel Blends (B5, B6, B7 and B8)

description: The present study aims to quantify black carbon (BC), particulate matter (PM1.0 and PM2.5, particles with diameter ≤ 1.0 and 2.5 µm, respectively) levels and their variability during the combustion of biodiesel/diesel blends used in heavy-duty vehicles. The samplings were conducted in the years 2014, 2016 and 2017 inside a semi closed bus station, a direct source of emission from engines burning blends of B5 to B8 biodiesel/diesel. Diesel engines using B5 and B6 presented a high contribution of BC in PM1.0 fraction representing 95 and 98% in mass, respectively. Results obtained from engines fueled with B7 and B8 diesel blends showed about 47% BC mass contribution in fine PM. The ratio PM1.0/PM2.5 remained relatively constant showing that the fine PM mass did not change significantly. Those measurements are important to follow the behavior of the addition of biodiesel in the diesel fuel as well as to help indicate a fingerprint of BC and PM2.5 concentrations in biodiesel increase.

title: Evaluation of an antibacterial orthodontic adhesive incorporated with niobium-based bioglass: an in situ study

description: Abstract This in situ study aimed to evaluate the antibacterial and anti-demineralization effects of an experimental orthodontic adhesive containing triazine and niobium phosphate bioglass (TAT) around brackets bonded to enamel surfaces. Sixteen volunteers were selected to use intra-oral devices with six metallic brackets bonded to enamel blocks. The experimental orthodontic adhesives were composed by 75% BisGMA and 25% TEGDMA containing 0% TAT and 20% TAT. Transbond XT adhesive (TXT) was used as a control group. Ten volunteers, mean age of 29 years, were included in the study. The six blocks of each volunteer were detached from the appliance after 7 and 14 days to evaluate mineral loss and bacterial growth including total bacteria, total Streptococci, Streptococci mutans, and Lactobacilli. Statistical analysis was performed using GLM model - univariate analysis of variance for microhardness and 2-way ANOVA for bacterial growth (p&lt;0.05). The 20% TAT adhesive caused no difference between distances from bracket and the sound zone at 10-µm deep after 7 and 14 days. After 14 days, higher mineral loss was shown around brackets at 10- to 30-µm deep for TXT and 0% TAT adhesives compared to 20% TAT. S. mutans growth was inhibited by 20% TAT adhesive at 14 days. Adhesive with 20% TAT showed lower S. mutans and total Streptococci growth than 0% TAT and TXT adhesives. The findings of this study show that the adhesive incorporated by triazine and niobium phosphate bioglass had an anti-demineralization effect while inhibiting S. mutans and total Streptococci growth. The use of this product may inhibit mineral loss of enamel, preventing the formation of white spot lesions.

title: Malocclusion and dental appearance in underprivileged Brazilian adolescents

description: Abstract Satisfaction with dental aesthetics is a subjective indicator used in epidemiological studies and is related to health behaviours. Little is known about the factors that influence this indicator, particularly among adolescents who live in a situation of social vulnerability. The aim of this study was to investigate the relationship between malocclusion and dental appearance in underprivileged Brazilian adolescents. This analytical cross-sectional study was conducted in Piracicaba, Brazil, and evaluated 884 adolescents from 13 to 19 years of age. The dependent variable was satisfaction with dental appearance, and the independent variables were classified as individual (components of the Dental Aesthetic Index - DAI, sex and age) and contextual (social exclusion index). For statistical analysis, multilevel regression models were estimated. The individual variables were considered Level 1, and the contextual variable was considered Level 2, with a level of significance of 5%. The mean age of the adolescents was 15.3 years. Female adolescents more frequently affirmed that they were satisfied with their dental appearance than did male individuals. There was an increase in dissatisfaction with oral health with the increase in anterior maxillary overjet, midline diastema, larger anterior irregularity in the maxilla, larger anterior irregularity in the mandible, anterior open bite and antero-posterior molar relation. Satisfaction with dental appearance was associated with individual factors such as sex and DAI components.

title: A novel application of nano eggshell/titanium dioxide composite on occluding dentine tubules: an in vitro study

description: Abstract To synthesize Nano eggshell-titanium-dioxide (EB@TiO2) biocomposite and to evaluate its effectiveness in occluding opened dentine tubules. EB@TiO2 was synthesized and characterized using X-ray diffraction (XRD), and Transmission Electron Microscope (TEM). Sixteen simulated bovine dentine discs were prepared and randomly assigned into four groups according to the following treatment (n = 4): Group 1: No treatment; Group 2: eggshell powder; Group 3: EB@TiO2; Group 4: Sensodyne. These were then agitated in a solution of 1g powder and 40mL water for 3hours. Thereafter, each dentine discs from the respective groups were post-treated for 5 min with 2wt% citric acid to test their acid resistant characteristics. Scanning Electron Microscope (SEM) was used to observe the effectiveness of occluded dentine pre-and post-treatment. The cytotoxicity of the synthesized EB@TiO2 was tested using NIH 3T3 assay. ANOVA was used to evaluate the mean values of the occluded area ratio and the data of MTS assay. This was followed by a multi-comparison test with Bonferroni correction (α = .05). The XRD confirmed that EB@TiO2 was successfully modified through ball-milling. The TEM revealed the presence of both spherical and irregular particle shape powders. The SEM result showed that EB@TiO2 could effectively occlude open dentine tubules. Equally, the result demonstrated that EB@TiO2 exhibited the highest acid resistant stability post-treatment. NIH 3T3 assay identified that EB@TiO2 had little effect on the NIH 3T3 cell line even at the highest concentration of 100µg/ml. This study suggests that the application of EB@TiO2 effectively occluded dentine tubules and the occlusion showed a high acid resistant stability.

title: Rheumatic heart disease in the modern era: recent developments and current challenges

description: Abstract Rheumatic heart disease (RHD) remains a major cause of preventable death and disability in children and young adults. Despite significant advances in medical technology and increased understanding of disease mechanisms, RHD continues to be a serious public health problem throughout the world, especially in low- and middle-income countries. Echocardiographic screening has played a key role in improving the accuracy of diagnosing RHD and has highlighted the disease burden. Most affected patients present with severe valve disease and limited access to life-saving cardiac surgery or percutaneous valve intervention, contributing to increased mortality and other complications. Although understanding of disease pathogenesis has advanced in recent years, key questions remain to be addressed. Preventing or providing early treatment for streptococcal infections is the most important step in reducing the burden of this disease.
