title: Nephrometry scores and perioperative outcomes following robotic partial nephrectomy

description: ABSTRACT Objectives: Based on imaging features, nephrometry scoring systems have been conceived to create a standardized and reproducible way to characterize renal tumor anatomy. However, less is known about which of these individual measures are important with regard to clinically relevant perioperative outcomes such as ischemia time (IT), estimated blood loss (EBL), length of hospital stay (LOS), and change in estimated glomerular filtration rate (eGFR) after robotic partial nephrectomy (PN). We aimed to assess the utility of the RENAL and PADUA scores, their subscales, and C-index for predicting these outcomes. Materials and Methods: We analyzed imaging studies from 283 patients who underwent robotic PN between 2008 and 2014 to assign nephrometry scores (NS): PADUA, RENAL and C-index. Univariate linear regression was used to assess whether the NS or any of their subscales were associated with EBL or IT. Multivariable linear regression and linear regression models were created to assess LOS and eGFR. Results: The three NS were significantly associated with EBL, IT, LOS, and eGFR at 12 months after surgery. All subscales with the exception of anterior/posterior were significantly associated with EBL and IT. Collecting system, renal rim location, renal sinus, exophytic/endophytic, and nearness to collecting system were significant predictors for LOS. Only renal rim location, renal sinus invasion and polar location were significantly associated with eGFR at 12 months. Conclusions: Tumor size and depth are important characteristics for predicting robotic PN outcomes and thus could be used individually as a simplified way to report tumors features for research and patient counseling purposes.

title: Análise comparativa entre diferentes ensaios porosimétricos em alumina macroporosa

description: ABSTRACT Macroporous ceramics of Al2O3 are being studied due their diverse applications (biomaterials, anode for solid oxide fuel cells, etc.). The pore distribution, size and interconnection are important parameters that can determine physical and mechanical characteristics of these materials. The aim of this study was analyze and compare different methods of porosimetry. For this, we used the mercury intrusion porosimetry (PIM), Archimedes method (MA), micrographic analysis (AM) and nuclear magnetic resonance with CPMG radiofrequency pulses (1H-RMN - CPMG). Samples of macroporous Al2O3 were obtained by the gelcasting method modified by incorporation of polyethylene spheres at different amounts. The results of these porosimetry methods were treated mathematically, and then the Pearson correlation between the pore size distributions were analyzed. The main advantage of the MA was the simplicity to obtain the apparent porosity, although this method did not provide the pore size distribution. The pore size distribution obtained by 1H-RMN - CPMG was similar to those obtained by PIM. The similarity of these results was evidenced by the high value of Pearson correlation (r &gt; 0.962) between these methods. The analysis of pore homogeneity and morphology were better obtained by AM method. Although, when AM were compared with PIM we observed differences in the pore size distribution. These were evidenced by the low value of Pearson correlation (r &lt; 0.048). Thus, unconventional porosimetry methods (1H-RMN - CPMG and AM) could be used as an alternative to conventional (PIM and MA) to characterize macroporous materials.

title: Electrochemical treatment of industrial effluents - alternative for contaminants removal and H2 obtainment

description: ABSTRACT The electrochemical treatment as an alternative technological resource for the treatment of industrial effluents has attracted considerable attention through the last years because of important characteristics such as easy automation, high efficiency and versatility in a short period of time besides requiring less physical space for its units. As the electron is the main “reagent” in an electrochemical process, the use of chemicals is reduced. This and the possibility of using coproducts generated during the electrochemical treatment processes configure relevant opportunities in the actual global energy and sustainability scenario. These technologies may include the use of renewable energy sources such as Hydrogen, a cathodic coproduct of great ambiental and economical interest that could be obtained and stored. In this context, the selection of electrodes materials, especially those for anodic steps, are fundamental. The efficiency and sustainability of the electrochemical processes relies on materials with properties such as low electrochemical impedance and high corrosion resistance besides high electro activity for the oxidation of the compounds of interest. The purpose of this article is to present some of the results of the electrochemical treatment developed by Labcorr aiming the removal of NH3-N and COD from industrial effluents. Electrochemical techniques were used for anodic and cathodic materials selection. The use of NaOCl as indirect oxidant was evaluated. Results indicated that a parallel plate reactor with DSA anodes and carbon steel cathodes and NaOCl injections at the beginning of the treatment process and in an intermediary point was an effective configuration for the removal of the compounds of interest. There is also a good indication of the possibility of nitrite and Hydrogen obtainment. The former could be used as corrosion inhibitor and the later as an energy source for the electrochemical treatment system in a semi-autonomous way.

title: Prostate cancer in renal transplant recipients

description: ABSTRACT As patients with end-stage renal disease are receiving renal allografts at older ages, the number of male renal transplant recipients (RTRs) being diagnosed with prostate cancer (CaP) is increasing. Historically, the literature regarding the management of CaP in RTR's is limited to case reports and small case series. To date, there are no standardized guidelines for screening or management of CaP in these complex patients. To better understand the unique characteristics of CaP in the renal transplant population, we performed a literature review of PubMed, without date limitations, using a combination of search terms including prostate cancer, end stage renal disease, renal transplantation, prostate cancer screening, prostate specific antigen kinetics, immuno-suppression, prostatectomy, and radiation therapy. Of special note, teams facilitating the care of these complex patients must carefully and meticulously consider the altered anatomy for surgical and radiotherapeutic planning. Active surveillance, though gaining popularity in the general low risk prostate cancer population, needs further study in this group, as does the management of advance disease. This review provides a comprehensive and contemporary understanding of the incidence, screening measures, risk stratification, and treatment options for CaP in RTRs.

title: Exogenous Gibberellic Acid Ameliorates Salinity-Induced Morphological and Biochemical Alterations in Portulaca grandiflora

description: ABSTRACT: An investigation was carried out to estimate the NaCl stress and ameliorative effects of Gibberellic Acid (GA3) on Portulaca grandiflora Hook. A crop experiment was conducted (CRBD) where all the pots were irrigated to field capacity. The treatments were given as (T0) control without NaCl, (T1) 80 mM NaCl, (T2) 80 mM NaCl and 50 ppm GA3, (T3) 80 mM NaCl and 75 ppm GA3 and (T4) 80 mM NaCl and 100 ppm GA3. The samples were collected at 90 DAS. It was found that plants subjected to salt stress generally showed a reduction of vegetative growth. GA3 spraying on Portulaca grandiflora with 75 ppm showed a high amelioration effect on growth and on biochemical patterns, which enhanced salt tolerance. In Portulaca grandiflora, data showed that NaCl stress inhibited fresh and dry weight and further introduced significant deviation on some biochemical parameters. However, GA3 partially ameliorated growth and some biochemical parameters of Portulaca grandiflora under NaCl stress.

title: Open radical prostatectomy reproducing robot-assisted radical prostatectomy: Involving antegrade nerve sparing and continuous anastomosis

description: ABSTRACT Purpose: To present modified RRP using the same method as RALP and compare its surgical outcomes with RALP. Materials and Methods: Demographics, perioperative and functional outcomes of the 322 patients that underwent RRP (N=99) or RALP (N=223) at our institution from January 2011 through June 2013 were evaluated retrospectively. Postoperative incontinence and erectile dysfunction are involved functional outcomes. During the modified procedure, the bladder neck was dissected first as for RALP. After dissection of vas deference and seminal vesicle, the prostate was dissected in an antegrade fashion with bilateral nerve saving. Finally, the urethra was cut at the prostate apex. After a Rocco suture was applied, and then urethrovesical anastomosis was performed with continuous suture as for RALP. Results: Perioperative characteristics and complication rates were similar in the RRP and RALP groups except for mean estimated blood loss (p&lt;0.001) and operative time (p&lt;0.001). Incontinence rates at 3 and 12 months after RRP decreased from 67.6% to 10.1 and after RALP decreased from 53.4% to 5.4%. Positive surgical margin rates were non-significantly different in the RRP and RALP groups (30.3% and 37.2%, respectively). Overall postoperative potency rate at 12 months was not significant different in RRP and RALP groups (34.3% and 43.0%). Conclusions: RRP reproducing RALP was found to have surgical outcomes comparable to RALP. This technique might be adopted by experienced urologic surgeons as a standard procedure.

title: INEQUALITY REDUCTION AND DEMOCRACY IN BRAZIL: THE INCLUSION OF OUTSIDERS

description: This article examines the path of economic inequality in Brazil under the current democratic period. It demonstrates that a mechanism of inclusion of outsiders sharply reduced economic inequality. The path of such mechanism is described as being deployed through two sequential phases: (i) in the transition to democracy, the introduction of paradigmatic changes in the model of Brazilian social policies, which had produced a big divide between insiders and outsiders since the 30s; (ii) under universal suffrage, the convergence of conservative and left-wing parties around the preferences of the beneficiaries of those policies, namely minimum wage as well as education and health policies. Such research results challenge the explanatory power of the median voter and the power of the theories of the Left. Instead, they suggest that exogenous changes introduced redistributive policies under a critical juncture, which in turn have given place to endogenous changes in which political competition played a key role.
