title: Efficacy and safety of a single radiofrequency ablation of solid benign non-functioning thyroid nodules

description: ABSTRACT Objective The objective of our study is to evaluate the clinical outcomes and safety of radiofrequency thermal ablation (RFA) for benign thyroid nodules (BTNs) over a 1-year follow-up. Subjects and methods This is a monocentric retrospective study. Forty-eight patients with solid, non-functioning BTNs were treated by RFA using a 17G internally cooled electrode. We categorized thyroid nodules as small (≤ 12 mL), medium (12 to 30 mL), or large (over 30 mL). BTNs volume reduction, thyroid function, cosmetic and compressive score changes and side effect evaluation at 6 and 12 months were evaluated. Results BTN volume decreased significantly from baseline to 6 (mean percentage decrease of BTN volume was 66.8 ± 13.6%, p &lt; 0.001). At 12 months, the mean percentage reduction of BTN volume compared to six months was 13.7 ± 17.1% (p &lt; 0.001). At 6-month, symptom score had improved significantly (p &lt; 0.001) while it does not change significantly between 6 and 12 months. In particular, symptom score improved significantly in the medium (p &lt; 0.001) and large (p &lt; 0.01) subgroups. Cosmetic score improved significantly between baseline and 6 months (p &lt; 0.001) and between 6 and 12 months (p &lt; 0.01). In all the subgroups, cosmetic score improved significantly between baseline and 6 months, while between 6 and 12 months it improved significantly only in the large group (p &lt; 0.05). RFA was well tolerated. Only one patient experienced permanent right paramedian vocal cord palsy. Conclusions A single RFA treatment was effective in reducing BTNs volume, in particular small and medium nodules. Cosmetic score improved in all treated BTNs while symptom score only got better in the medium and large BTNs.

title: METHIONINE PLUS CYSTINE TO LYSINE RATIO IN DIETS FOR TAMBAQUI JUVENILES

description: ABSTRACT The objective of this study was to determine the appropriate ratio of methionine plus cystine to lysine in rations for tambaqui (Colossoma macropomum) juveniles, with initial weights of 0.28 ± 0.08 g and 0.94 ± 0.33 g. A randomized block design consisting of six treatments, five replicates in two blocks, and 20 fish per replicate was implemented. Six isolisinic (1.45%), isoenergetic, isophosphoric, and isocalcic diets, containing different ratios of methionine plus cystine to digestible lysine (50%, 55%, 60%, 65%, 70%, and 75%) were used. Performance and feed efficiency variables, including body composition (moisture, protein, and fat), daily protein deposition rate, daily fat deposition rate, and nitrogen retention efficiency, were evaluated. The specific growth rate and feed conversion presented quadratic effects, with maximum effects from the digestible methionine plus cystine to lysine ratio of 64.4% and 64.8%, respectively. The increase in digestible methionine plus cystine intake resulted in a linear reduction in body fat content with the elevation of the digestible methionine plus cystine to lysine ratio. The digestible methionine plus cystine to lysine ratio recommended in rations for tambaqui fingerlings is 64.8%.

title: Quality & finality: characteristics of Brazilian bioethics

description: Abstract This paper considers the 25 years of publication of Revista Bioética. In addition to outlining the current status of the journal, it will discuss the criteria currently used for measuring the quality of scientific publications, considering the specific nature of this field of study and research, and particularly theoretical aspects focused on the Brazilian reality. As a transdisciplinary field, bioethics permeates several areas of knowledge, encompassing the Biomedical Sciences, Law, Philosophy and Social Sciences in order to respond to conflicts and impasses related to life and health. As a result, the consolidation of Bioethics in Brazil should be considered a gradual process, which covers both professional training in a broad and narrow sense, as well as its insertion as a transversal discipline in Health and Law degrees and related areas that can benefit from bioethical reflection.

title: THE PORT REGION OF RIO DE JANEIRO IN THE 19TH CENTURY: DEMOGRAPHIC AND SOCIAL ASPECTS

description: Abstract This brief article aims at analyzing the port region of Rio de Janeiro in the 19th century, through its urban evolution, in a manner consistent with the demographic dynamics imposed on the city in the global, national and regional spheres. Based on its economic and social characteristics, marked by the operation of the port with the busiest traffic of people and goods in the Southern hemisphere, we will try to demonstrate how the port parishes supported a great population density, being the most populous of the largest and capital city of the Brazilian Empire. We will also try to trace an ethnic-social profile of the population that occupied the region, demonstrating their common character: the poverty.

title: Thermal resistance and conductivity of recycled construction and demolition waste (RCDW) concrete blocks

description: Abstract In Brazil, studies to reuse construction and demolition waste are a special issue because a large amount of this material has been delivered to the public landfills and in illegal places. Some researchers have suggested reusing this material in building elements, such as bricks or blocks. It is possible to find a lot of researches in physical/mechanical characterization, while little effort has been made to characterize recycled construction and demolition waste blocks (RCDW) for their thermal properties. The aim of this work was to characterize the RCDW thermal resistance and conductivity in order to provide subsidies for a building's thermal performance analysis. The hot-box method was adapted, together with measuring techniques with a heat-flow meter to determine the RCDW thermal properties. The results indicated that the RCDW block overall thermal resistance and thermal conductivity in the solid region was within the intervals of 0.33≤RT≤0.41m2KW-1 and 0.60≤l≤0.78Wm-1K-1, respectively. The lower resistance and conductivity values are justified by the presence of aggregate with a lower density and lower thermal conductivity than the natural aggregate.

title: THE RIVERS, THE CITY AND THE MAP AS AN OBJECT OF ANALYSIS OF LANDSCAPE DYNAMICS

description: Abstract Historical cartography has been increasingly important in understanding the landscape transformations, especially in the urban environment where different historical records are used. The present work aims at identifying and comparing, from historical and current records, the changes occurred in the three main rivers that cut the genesis area of the city of Petrópolis (Quitandinha, Palatino and Piabanha). The main research material consists of the Koeler Map (1846), a document that guides the urban planning of the city of Petrópolis, which was designed in line with the drainage network, produced in a 1: 5,000 scale and the most recent cartographic base of the city (1999) in scale 1: 10,000. The georeferencing and vectorization of the Koeler Map made it possible to perform different measurements, such as river width and winding. Later, the same procedures were performed on the most recent cartographic base of the city, in order to create comparative parameters for changes in the course of the rivers and their floods. The results show the suppression of four river islands and a decrease of sinuosity of the rivers with a variation of +0.575% to -2.436%. In the Quitandinha river were recorded the biggest changes and the largest flood record (97%), indicating that changes in the drainage network are significant elements in understanding flood dynamics.

title: BIBLIOMETRIC ANALYSIS OF THE RESEARCH IN TRANSLATION STUDIES AND INTERPRETATION AT DOCTORAL LEVEL IN BRAZIL

description: Abstract This article derives from an international collaboration between the UFRN and BITRA (Bibliography in Interpreting and Translation – University of Alicante, Spain) in which, given the paucity of data about academic production dealing with Brazilian Translation Studies (TS), we attempt to throw some light about the nature and evolution of TS in Brazil. Our main aim is to present a critical overview of TS in Brazil based on the mining of doctoral theses submitted to Brazilian federal, state or private universities. To this end, we mined BITRA, institutional repositories, the IBICT and the theses and dissertations repository of the CAPES. The systematization of the data was performed following thestructure of BITRA, which will be presented in this article together withother bibliometric methodological criteria. As a result, we identified 374Ph.D. theses dealing with TS and submitted to Brazilian universities, allof which will comprise our main corpus.

title: Copper Cobalt Magnetic Ceramic Materials Characterization at Terahertz Frequencies

description: ABSTRACT: This study presents the complex index of refraction and the complex permittivity of a magnetic ceramic material made of copper, cobalt, and iron oxides. The index of refraction and the extinction coefficient of the CuCo-ferrite exhibit an almost frequency independent behavior and were averaged to n = 3.62 ± 0.05 and k = 0.06 ± 0.02, respectively, over the frequency range from 0.2 to 1 THz. The corresponding complex permittivity was ε' = 13.12 ± 0.35 for the real part and ε'' = 0.46 ± 0.15 for the imaginary one. The absorption coefficient and the transmittance of the CuCo-ferrite were also determined. The absorption coefficient exhibits a dip at ~0.35 THz, which corresponds to a peak in transmittance at this frequency. The impact of the observations on the potential realization of novel THz electronic devices is discussed.

title: Deaths related to differentiated thyroid cancer: a rare but real event

description: ABSTRACT Objective The present study describes the clinical and tumor characteristics of patients that died from differentiated thyroid cancer and reports on the cause and circumstances of death in these cases. Subjects and methods Retrospective analysis of all the differentiated thyroid cancer (DTC) related deaths at a single institution over a 5-year period, with a total of 33 patients. Results Most of the patients were female (63.6%), with a mean age at diagnosis of 58.2 years. The most common histologic type was papillary (66.7%) and 30.3% were follicular. The distribution according to the TNM classification was: 15.4% of T1; 7.7% T2; 38.4% T3; 19.2% of T4a and 19.2% of T4b. Forty-four percent of cases were N0; 20% N1a and 36.6% of N1b. Twelve patients were considered non-responsive to radioiodine. Only one of the patients did not have distant metastases. The most common metastatic site was the lung in 69.7%. The majority of deaths were due to pulmonary complications related to lung metastases (17 patients, 51.5%), followed by post-operative complications in 5 cases, neurological disease progression in 3 cases, local invasion and airway obstruction in one patient. Median survival between diagnosis and death was reached in 49 months while between disease progression and death it was at 22 months. Conclusion Mortality from DTC is extremely rare but persists, and the main causes of death derive from distant metastasis, especially respiratory failure due to lung metastasis. Once disease progression is established, median survival was only 22 months.
