As the prevalence of urolithiasis is growing and there has been an increase in technologies and minimally invasive techniques in all areas of surgery, it would be expected that the total number of publications about this disease should increase. We hypothesized if there is also an evident trend towards the increase of urolithiasis related publications in urology journals. We evaluated the publications in five prestigious urology journals over the last decade, in order to perform a bibliometric analysis of every article published related to urinary lithiasis. An electronic search was performed using PubMed and all issues of British Journal of Urology International® (BJU Int), European Urology® (Eur Urol), Journal of Endourology® (J Endourol), Journal of Urology® (J Urol) and Urology® (Urology) were consulted from 2001 to 2010. All articles related to renal and ureteral lithiasis were collected, recorded and analyzed. A total of 30, 847 articles were published in these five prestigious journals. The J Urol was the journal with the most number of articles published per year with an average of 1146 papers. J Endourol was the publication with less publicated articles in this decade, with an average of 231 papers per year. There was a total of 1425 urolithiasis related papers in all journals. The J Endourol was the journal with the greatest number of urolithiasis related articles published in the period of analysis, with a total of 545 articles. The ratio of urolithiasis related articles and the total articles published per year in each journal was analyzed. The J Endourol was the publication with the greatest ratio. Eur Urol was the journal with less publications in urolithiasis, with ratios ranging from 0 in the year of 2010 and 5.3% in the year of 2003, with a decrease in the last years. All the other journals maintained a stable ratio of publications. Urolithiasis as a great subject to urologists practice would be expected to be an important source of original research studies in the more active urology journals. However, our study showed that, during the last decade, there was a steady number of urolithiasis related articles published in several journals.

Nowadays, construction sector tries to implement several options to solve the issues related to concrete. The main goal of this work was to study the effect of biomass fly ash, blended with coal fly ashes or alone, as cement replacement in the mortars properties. Mortars with biomass fly ashes have lower slump value than the reference. Mortars with 20% of cement substitution presents better results for all curing time. However, in the three percentages of substitution, and for all curing periods, the best results were found for mortars composed with biomass fly ashes. This work showed that is possible to use biomass fly ashes as partial cement substituent with good results in terms of durability and quality of concrete. Its utilization at an industrial level of concrete production can decrease the energy and raw materials consumption related to cement production and allows a more sustainable option on the ash management., FCT (Fundação para a Ciência e Tecnologia – Portugal) and to the Doctoral Program Eco-Construction and Rehabilitation for supporting the PhD scholarship (with the reference PD/BD/52661/2014)

After the 1755 earthquake that destroyed Lisbon, an innovative anti-seismic structural system was developed consisting of a timber skeleton, that included timber framed masonry walls. After more than 250 years these structures need rehabilitation to face the present demands. The research presented in this paper aimed at experimentally characterizing the cyclic behaviour of timber framed walls reinforced with three different methods, namely: (i) elastic-plastic dampers on diagonal braces, (ii) reinforcement of timber connections with steel plates, (iii) application of a reinforced rendering. The elastic-plastic damper showed an unsymmetrical behaviour and some difficulties to implement in practice. The strengthening with reinforced render led to an initial stiffness increase but showed a limited deformation capacity. The walls with reinforcing steel plates at the timber connections showed the best behaviour in terms of strength, stiffness and energy dissipation., Después del terremoto de 1755 que destruyó Lisboa, un sistema estructural antisísmico muy innovador fue desarrollado. El sistema consistió en un esqueleto de madera, que incluyó la construcción de muros de mampostería con un entramado de madera. Transcurridos más de 250 años, estas estructuras necesitan rehabilitación para poder hacer frente a los requisitos estructurales actuales. La investigación presentada en este trabajo tiene como objetivo caracterizar experimentalmente el comportamiento cíclico de los muros con entramado de madera reforzados con tres métodos diferentes: (i) amortiguadores elasto-plásticos, (ii) refuerzo de las conexiones de madera con placas de acero, (iii) aplicación de un mortero reforzado. El amortiguador elasto-plástico mostró un comportamiento asimétrico y algunas dificultades para aplicarlo en la práctica. El refuerzo con mortero reforzado condujo a un aumento de la rigidez inicial, pero reveló una capacidad de deformación limitada. Los muros con placas de refuerzo de acero en las conexiones de madera mostraron el mejor comportamiento en términos de resistencia, rigidez y disipación de la energía.

The present paper describes the construction process of a full-scale innovative GFRP-concrete hybrid footbridge, and summarizes the main tests performed. This footbridge is 11 m long, 2 m wide, simply supported, and composed of two pultruded I-shaped GFRP girders (0.2 m x 0.4 m) and a 0.04 thick deck in steel fiber reinforced self-compacting concrete (SFRSCC). To evaluate the static and dynamic behavior of this footbridge, short and long-term load tests, and dynamic tests were performed., (undefined)

Desde a dispersão da mosca-dos-chifres, no Brasil, queixas sobre seu controle aumentaram em todo o país. Um amplo levantamento objetivando avaliar a suscetibilidade da mosca a inseticidas organofosforados (OF) e piretróides foi realizado de outubro de 2000 a abril de 2003. Bioensaios com papéis de filtro impregnados com cipermetrina, permetrina ou diazinon foram conduzidos em 154 populações da mosca-dos-chifres de 14 Estados e 78 municípios. Resistência à cipermetrina, ingrediente ativo presente na maioria dos produtos para controle da mosca-dos-chifres no Brasil, foi detectada em 98,46% das populações, com fatores de resistência (FR) variando de 2,5 a 719,9. Resistência à permetrina (FR ≤ 6,3) foi encontrada em 96,67% das populações testadas, apesar da falta de uso de produtos contendo este princípio ativo. Em geral, resistência a piretróides foi detectada em 97,18% das populações, com frequências acima de 87% em todas as regiões do país. A situação da suscetibilidade da mosca-dos-chifres a inseticidas, no Brasil, pode ser caracterizada por uma elevada suscetibilidade aos organofosforados e ocorrência generalizada de resistência aos piretróides, potencialmente comprometendo a eficácia desses produtos na maioria dos casos. Embora resultados parciais tenham sido apresentados anteriormente, um quadro geral da suscetibilidade da mosca-dos-chifres no Brasil é apresentado pela primeira vez.

Angioedema owing to hereditary deficiency of C1 inhibitor (HAE) is a rare, life-threatening, disabling disease. In the last 2 years, the results of well-designed and controlled trials with existing and new therapies for this condition have been published, and new treatments reached the market. Current guidelines for the treatment for HAE were released before the new trials and before the new treatments became available and were essentially based on observational studies and expert opinion. To provide evidence-based HAE treatment guidelines supported by the new studies, a conference was held in Gargnano del Garda, Italy, from September 26 to 29, 2010. The meeting hosted 58 experienced HAE expert physicians, representatives of pharmaceutical companies and representatives of HAE patients' associations. Here, we report the topics discussed during the meeting and evidence-based consensus about management approaches for HAE in adult/adolescent patients.

O betão autocompactável (BAC) é um material com um comportamento que pode ser considerado intermédio entre o de um fluido e o de um aglomerado húmido de partículas. Podem então ser aplicados conceitos da reologia que permitam caracterizar este material em função de propriedades intrínsecas como a tensão de cedência e a viscosidade. Assim, é essencial o estudo reológico para o desenvolvimento dos betões. O BAC pode ser descrito como uma suspensão de agregados grossos na argamassa constituinte. Como tal, o seu comportamento no estado fresco será condicionado pelas características reológicas da argamassa. Reduzindo a escala de observação, o comportamento das argamassas pode ser avaliado tomando-as como suspensões de agregados finos numa pasta. E sucessivamente, a pasta é uma suspensão de material fino, essencialmente de ligante numa solução líquida de água e adjuvantes. Nestes termos a compreensão do comportamento reológico dos BAC tem de passar pela identificação e avaliação dos parâmetros que condicionam esse comportamento e o das diferentes fases do betão – pasta e argamassa. Com o objectivo de contribuir para o conhecimento científico do comportamento dos BAC foi realizada uma tese de doutoramento da qual se apresentam, nesta comunicação, os resultados obtidos no estudo efectuado em argamassas. Neste estudo pretendeu-se avaliar a variação do comportamento das argamassas em função dos seguintes factores: características da pasta, características da areia e teor da pasta. Nesta avaliação foram efectuados os seguintes ensaios: espalhamento, escoamento no funil e reometria. Na presente comunicação serão divulgados resultados que permitam o estabelecimento de relações entre as diferentes fases das argamassas, que possam ser utilizadas como ferramentas na estimativa do comportamento reológico das argamassas e por conseguinte nos dos BAC. 9 7 10p DM/NB 2010 1 a 2 de Julho

It is generally accepted that menopause significantly modifies cardiovascular risk. The effects of hormone replacement therapy (HRT) on this risk remain controversial. Aim: To study the prevalence of cardiovascular risk factors (RF) in middle-aged women and their changes with aging, menopause and hormone replacement therapy (HRT). Material and methods: cardiovascular risk factors were assessed in 576 women aged 40 to 59 years in 1991-92. Five years later, 467 of these women were reassessed. Results: Sedentarism (87.2%), dyslipidemias (71.5%), high blood pressure (13.5%), obesity (13.1%), smoking (12.4%) and diabetes (2.8%) were the most prevalent RF. Five years later, the prevalence of hypertension increased to 20.9%, the prevalence of obesity increased to 27.3%, smoking increased to 20.8% and diabetes to 5.9%. The prevalence of dyslipidemia did not change, although triglycerides levels rose from 125.9±56.4 to 136.8±63.5 mg/dl (p

Los gestágenos clásicamente han sido relacionado con el cáncer mamario. Por esto, cuando se requiere indicar un anticonceptivos hormonal en una paciente tratada por cáncer de mama, surge la opción del uso de anticonceptivos con gestágenos solos (POP). Algunos estudios sugieren un rol protector de los gestágenos en el cáncer de mama: 1) La progesterona inhibe la proliferación mamaria inducida por el estradiol. 2) Induce apoptosis celular, inhibiendo la síntesis de las proteínas antiapoptóticas, 3) Inhibe enzimas que aumentan la concentración de estrógenos en la mama. Contrariamente, otras investigaciones muestran una acción favorecedora del cáncer de mama: 1) La actividad mitótica en las mamas es máxima durante la fase lútea, período en que predomina la progesterona. 2) En cultivos celulares los gestágenos estimulan la proliferación de algunas líneas celulares de cáncer de mama. 3) El uso de anticonceptivos orales con progestágenos y la medroxiprogesterona de depósito aumentan en mujeres jóvenes el riesgo de cáncer mamario. 4) En el reemplazo hormonal postmenopáusico varios estudios sugieren que la medroxiprogesterona incrementa el riesgo oncogénico. Conclusión: No existen datos que permitan afirmar con certeza que el uso de POP no tiene riesgos en pacientes con cáncer de mama

The application of active control systems to reduce wind vibrations in bridges is a new area of research. This paper presents the results that were obtained on a set of wind tunnel tests of a bridge model equipped with active movable flaps. Based on the monitored position and motion of the deck, the flaps are regulated by a control algorithm so that the wind forces exerted on them counteract the deck oscillations.
