Effect of a Single Shot Sciatic Nerve Block Combined with a Continuous Femoral Block on Pain Scores After Knee Arthroplasty. A Randomized Controlled Trial  [PDF]
R Carvalho, L Calixto, JP Bragana
Open Journal of Anesthesiology (OJAnes) , 2012, DOI: 10.4236/ojanes.2012.24025
Abstract: Background and Purpose: Postoperative pain after knee arthroplasty (TKA) is reported as severe in up to 60% of patients. Continuous femoral nerve blocks (CFNB) are a choice for major knee repair, but controversies remain about the need of supplemental sciatic nerve blocks (SNB) for better analgesia. Our aim is to assess the effect of the association of a SNB to a CFNB to reduce postoperative pain after TKA. Methods: A prospective randomized, single blinded, controlled study, on 50 patients undergoing TKA. Control group received a CFNB before general anesthesia; in the intervention group a single shot SNB was added after the CFNB was done. After the end of surgery all patients started a continuous local anesthetic infusion through the femoral catheter in the PACU (post-anesthesia care unit). Pain scores were measured in the PACU and at 12 h and 24 h postoperative using a visual analog scale (VAS). Results: VAS pain scores (mm) were lower and statistically significant for the intervention group up to 12 h postoperative: PACU admission mean VAS = 59.4 vs 30.2, P = 0.001; at 12 h mean VASr = 26.1 vs 9.2, P = 0.006; at 24 h mean VASr = 30.1 vs 32.7, P = 0.723. Conclusions: The association of a single shot SNB with a CFNB significantly reduces postoperative pain scores after TKA up to 12 h. At 24 h there are no differences between groups.
A cultura do algod?o e a quest?o da integra??o entre pre?os internos e externos
Coelho, Alexandre Bragana;
Revista de Economia e Sociologia Rural , 2004, DOI: 10.1590/S0103-20032004000100008
Abstract: este artigo tem como objetivo analisar a intera??o entre pre?os internos e externos do algod?o nas últimas duas décadas para determinar se a abertura comercial ocorrida na década de 90 representou um aumento da influência dos pre?os externos sobre os pre?os internos da pluma no país. para este fim, a metodologia escolhida foi a análise de co-integra??o, especificamente o procedimento de johansen. os resultados obtidos com a análise da amostra completa indicam que o mercado brasileiro e o norte-americano podem ser considerados perfeitamente integrados. dividindo a amostra, os resultados referentes à década de 80 mostram que o mercado brasileiro de algod?o em pluma pode ser considerado como um mercado fechado neste período, enquanto na década de 90 os resultados indicam que o mercado brasileiro pode ser considerado integrado aos mercados internacionais.

Registros documentais no cinema da Revolu??o Mexicana
Bragana, Maurício de;
História (S?o Paulo) , 2007, DOI: 10.1590/S0101-90742007000200008
Abstract: this article shows the connections between cinema and history in the two first decades in xx century in mexico. the cinema arrived in mexico in a session dedicated to porfirio díaz. the president soon became the first star movie in mexican cinema, interested in its publicity potencial. the movies were seen as historical documents that pointed the true. the mexican revolution redefined the cinema role showing the social movement by the contact between the filmaker and the national politic moment. the development of the revolution after its battle phase, and the process of institucionalization of its discourse in the official sphere removed the protest power from the documental images. the image of zapata dead body went all the country through and became a emblem of this project.
Parametros para o estudo da sinestesia na música
Bragana, Guilherme Francisco Furtado;
Per Musi , 2010, DOI: 10.1590/S1517-75992010000100010
Abstract: this paper studies the relationship between synaesthesia as a neurological condition and synaesthesic metaphor. it aims at investigating synaesthesia as a way of conscious listening and proposes a synaesthesic listening of the 5th movement joie du sang des étoiles of olivier messiaen's turangal?la, including an analysis of the relationship between the elements found in the synaesthesic listening and the structure of the work. relating analysis and phenomenology, it also suggests a systematization of synaesthesics categories, departing from the sound as the primary sensation among the most common sensations.
Estatística em psiquiatria
Pereira, Basilio de Bragana;
Revista Brasileira de Psiquiatria , 2001, DOI: 10.1590/S1516-44462001000300010
Abstract: this paper presents the paradigms of data analysis-based research work. it shows how the advances in computer sciences have influenced this process, allowing complex systems to be modeled and analyzed. some fields in psychiatry where statistical analyses are important are assessed, and suggestions are given on how to improve the collaboration between psychiatrists and statisticians.
Corpo, imagem e registro colonial no Corazón Sangrante de Astrid Hadad
Bragana, Maurício de;
Revista Estudos Feministas , 2011, DOI: 10.1590/S0104-026X2011000200006
Abstract: in this article, we present a discussion about the use of the heart as an important allegorical element of recognition of a collective identity in latin america. the work of astrid hadad, a mexican performer-cabaretera, of maya-lebanese origin, points to the criticism of a control policy that organizes gender models in mexico. the experience of colonization in latin america was guided by discursive strategies which employed the heart as an important allegory of subordination, especially that of women. in her video clip corazón sangrante, using the linguistic strategies of the melodrama, hadad uses the ambiguity of irony to approach this issue, pointing to colonial marks in the contemporary mexican culture.

On the Periodic Cauchy problem for a coupled system of third-order nonlinear Schr?dinger equations
Marcia Scialom,Luciana Bragana
Mathematics , 2014,
Abstract: We investigate some well-posedness issues for the initial value problem (IVP) associated to the system \begin{equation} \{ \begin{array} [c]{l} 2i\partial_{t}u+q\partial_{x}^{2}u+i\gamma\partial_{x}^{3}u=F_{1}(u,w)\\ 2i\partial_{t}w+q\partial_{x}^{2}w+i\gamma\partial_{x}^{3}w=F_{2}(u,w), \end{array} . \end{equation} where $F_{1}$ and $F_{2}$ are polynomials of degree 3 involving $u$, $w$ and their derivatives. This system describes the dynamics of two nonlinear short-optical pulses envelopes $u(x,t)$ and $w(x,t)$ in fibers (\cite{31}, \cite{14}). We prove periodic local well-posedness for the IVP with data in Sobolev spaces $H^{s}(\mathbb{T)\times} H^{s}(\mathbb{T)}$, $ s\geq 1/2$ and global well-posedness result in Sobolev spaces $H^{1}(\mathbb{T)\times }H^{1}(\mathbb{T)}$.
FBC desulfurization process using coal with low sulfur content, high oxidizing conditions and metamorphic limestones
Bragana, S. R.;Castellan, J. L.;
Brazilian Journal of Chemical Engineering , 2009, DOI: 10.1590/S0104-66322009000200015
Abstract: a metamorphic limestone and a dolomite were employed as so2 sorbents in the desulfurization of gas from coal combustion. the tests were performed in a fluidized bed reactor on a bench and pilot scale. several parameters such as bed temperature, sorbent type, and sorbent particle size at different ca/s molar ratios were analyzed. these parameters were evaluated for the combustion of coal with low-sulfur/high-ash content, experimental conditions of high air excess and high o2 level in fluidization air. under these conditions, typical of furnaces, few published data can be found. in this work, a medium level of desulfurization efficiency (~60%) for ca/s = 2 was obtained.
