title: Polyclonal anti T-lymphocyte antibody therapy monitoring in kidney transplant recipients: comparison of CD3+ T cell and total lymphocyte counts

description: ABSTRACT Objective: To investigate the correlation between total lymphocyte and CD3+ T cell counts in peripheral blood in renal transplant patients treated with anti-thymocyte globulin, and discuss related outcomes. Methods: A single-center, retrospective study involving 226 patients submitted to kidney transplant between 2008 and 2013, and treated with anti-thymocyte globulin for induction or treatment of cellular rejection. Doses were adjusted according to CD3+ T cell or total lymphocyte counts in peripheral blood. Results: A total of 664 paired samples were analyzed. The Spearman's correlation coefficient was 0.416 (p&lt;0.001) for all samples combined; the overall Kappa coefficient was 0.267 (p&lt;0.001). Diagnostic parameters estimated based on total lymphocyte counts were also calculated using the number of CD3+ T cells (gold standard), with a cut off of &gt;20 cells/mm3. Conclusion: Total lymphocyte and CD3+ T cell counts in peripheral blood are not equivalent monitoring strategies in anti-thymocyte globulin therapy.

title: Influence of sediment distribution on the relationships among reservoir yield, spill, and evaporation losses

description: ABSTRACT This study shows how the sedimentation process in reservoirs affects the yield-spill-evaporation losses in reservoirs of Ceará State, Brazilian Northeast. Reservoirs are assumed to have, initially, inverted conical shape. Three forms of sedimentation were investigated: type 1, with deposition occurring parallel to the wetted perimeter; type 2, deposition distributed proportionally to the water depth; and, type 3, deposition concentrated in the reservoir bottom. These sedimentation patterns were found in many reservoirs in Ceará, with capacity ranging from about 0.5 to 100 hm3. Nevertheless, type 2 pattern was the most frequent. In this paper, five large reservoirs, over 100 hm3, were studied using Monte Carlo approach, and considering the silting over the time horizon. It was found that sediment distribution can significantly affect the yield-spill-evaporation trade-off on large reservoirs. Type 1 results have the lowest impact on reservoir yield, followed by type 2 and type 3. For Cedro reservoir, the yield would go to zero in 2115, assuming a type 3 deposition pattern. These results reinforce the need for monitoring sedimentation in large reservoirs in the Brazilian semiarid region. In addition, this study provides a relatively simple methodology to predict the impact of siltation on reservoir yield-spill-evaporation relationships, for the three most found patterns of sedimentation.

title: A pilot study comparing bovine mesenteric artery and expanded polytetrafluoroethylene grafts as non-autogenous hemodialysis options

description: Abstract Background Many dialysis patients do not have the necessary conditions for construction of a native arteriovenous fistula (AVF). Expanded Polytetrafluoroethylene (ePTFE) vascular prostheses are the most widely-used option, but it is known that they are inferior to native vein AVFs. Objectives To identify a graft with superior performance to ePTFE, comparing their results with those of AVFs made from bovine mesenteric arteries treated with L-Hydro technology (Labcor Laboratories ®). Methods A prospective and controlled study of 10 patients with AVFs constructed with ePTFE and 10 patients with L-Hydro bioprostheses, matched for comorbidities. The variables studied were: primary patency, assisted primary patency, and secondary patency, surgical manipulability, and prevalence of infections. The performance of prostheses was assessed by duplex-scan and repeated consultations with health professionals at hemodialysis clinics. The chi-square test was used for statistical analysis. Results After 1 year of postoperative follow-up, secondary and primary patency rates were higher for L-Hydro than ePTFE AVFs. Fewer interventions were needed to maintain AVF patency in the L-Hydro AVF group. The most common complication was graft thrombosis, which was more frequent in the ePTFE group. While the figures indicate more favorable outcomes in the L-Hydro AVFs, this could not be confirmed with the statistical treatment employed. Conclusions The L-Hydro graft appears to be a valuable alternative option for AVFs, since it seems to require fewer interventions to maintain patency when compared to ePTFE grafts.

title: Potentialities and limitations of agricultural use in soils of semi-arid region of the state of Bahia

description: Abstract The objective of this study was to evaluate the potentialities and limitations of the agricultural use of representative classes of semi-arid regions of the state of Bahia, based on the pedological and evaluation of their soil characteristics. Five areas were selected where trenches were opened to collect samples for the analyses: Eutric Haplustept which presents vulnerability to physical and chemical degradation due to poor drainage with risks of erosion, waterlogging, salinization and compaction but having good natural fertility; Abrupt Kandiustalf with high vulnerability to physical degradation due to the presence of gravel and pebbles which may limit the development of deep rooting plants and mechanization but also with good natural fertility; Typic quartzipsaments and Typic Eutrustalf with no limitations related to drainage as low risk of compaction but featuring limitation of low moisture-holding capacity and nutrients; and Arenic Haplustulf wose characteristics are high vulnerability to degradation due to the drainage limitation related to the Btx horizon cementing in addition to low natural fertility and therefore is not recommended to agricultural use. However, in general, they feature no serious impediments for agricultural use. The amounts of OM is low in all soils but the use of management systems aiming at their accumulation and maintenance in appropriate levels will contribute to the CEC increase as well as to improve the chemical and physical properties.

title: Sexually Transmitted Infections Detected by Multiplex Real Time PCR in Asymptomatic Women and Association with Cervical Intraepithelial Neoplasia

description: Abstract Objective To determine the frequency of sexually transmitted infections (STIs) in asymptomatic women and the association of STIs with cervical intraepithelial neoplasia (CIN). Methods A cross-sectional studywas performed, enrollingwomen examined in a general gynecology clinic and in a colposcopy referral center fromOctober 2014 to October 2015. The colposcopy groupconsisted of 71women, and the general gynecologygroupconsisted of 55 women. Cervical samples were collected for cervical cytology and a multiplex realtime polymerase chain reaction (PCR) was developed to detect human papillomavirus (HPV) and the STIs caused by the following microorganisms: Chlamydia trachomatis, Mycoplasma hominis, Mycoplasma genitalium, Ureaplasma urealyticum, and Neisseria gonorrhoeae. A multivariate analysis was performed by logistic regression, considering the significance level of 0.05. Results The general frequency of STIs was: 46.8% (HPV); 27.8% (C. trachomatis); 28.6% (M. genitalium); 0.8% (M. hominis); 4.8% (U. urealyticum); and 4.8% (N. gonorrhoeae). The significant risk factors for CIN were: HPV infection (odds ratio [OR] = 2.53; p = 0.024); C. trachomatis (OR = 3.04; p = 0.009); M. genitalium (OR = 2.37; p = 0.04); and HPV and C. trachomatis coinfection (OR = 3.11; p = 0.023). After the multivariate analysis, a significant associationwas found betweenHPVand CIN(OR = 2.48; 95% confidence interval [95%CI]: 1.04-5.92; p = 0.04); and between C. trachomatis and CIN (OR = 2.69; 95%CI: 1.11-6.53; p = 0.028). Conclusion The frequency of STIs was high in asymptomatic patients. Infections by HPV and C. trachomatis were independently associated with the presence of CIN. The high frequency of STIs in asymptomatic women suggests the need for routine screening of these infections.

title: Index-based and compliance assessment of water quality for a Brazilian subtropical reservoir

description: ABSTRACT The Passaúna catchment is part of the Upper Iguaçu watershed and includes a water supply reservoir for over 500,000 inhabitants of Curitiba metropolitan region. The aim of this study was to establish the state of reservoir water quality, and whether it has undergone any recent medium- and long-term variations. A physical-chemical-biological assessment was undertaken using nine indicators and three indexes: Water Quality Index (WQI), Trophic State Index (TSI) and Shannon-Weaver Index (H’) for macroinvertebrate diversity. Compliance with the prescribed quality standards for the water body was verified using frequency curves. Two WQI calculation approaches were contrasted to test for conditions of partial data unavailability. Temporal trends in key parameters were assessed using Spearman’s rank correlation coefficient. WQI results from 1991-2014 indicated that the water quality may be classified as good and improved in the final decade of such period, while most TSI results were in the oligotrophic/mesotrophic range, but with no significant temporal trend. The biodiversity result of H’=1.6 obtained with data acquired in 2014 indicated a moderately degraded ecosystem that is typically associated with flow regulation and a degree of water quality impairment. Such a multi-indicator integrated physical-chemical-biological monitoring approach comprised a robust framework for assessments of medium-long term aquatic health.

title: Intake, apparent digestibility, rumen fermentation and nitrogen efficiency in sheep fed a tropical legume silage with or without concentrate

description: Abstract Legume silage can increase the forage quality of the diets as well as supply it with nitrogen, calcium and phosphorus. The objective was to evaluate the intake, apparent digestibility, rumen fermentation and nitrogen efficiency in sheep fed a tropical legume silage with or without concentrate. Twelve crossbred sheep with an average initial body weight of 32.2 ± 1.26 kg, with six animals cannulated in the rumen were distributed into four 3 × 3 Latin squares. The treatments were 1) Stylosanthes silage without concentrate (StS), 2) Stylosanthes silage with concentrate (StS+C), and 3) corn silage with concentrate (CS+C). StS diet showed lowest intake, except for neutral detergent fiber (NDF). The diets StS+C and CS+C showed similar intake of dry matter (DM) and crude protein. The intake of total digestible nutrients was higher for CS+C diet than diets StS+C and StS. Animals fed CS+C diet had lowest ruminal pH. The nitrogen use efficiency was similar for the diets with concentrate. In conclusion, StS+C diet replacing CS+C diet decreases the intake of total digestible nutrients.

title: The subprime crisis and the fourth dimension of capitalism - an Marxist approach

description: Abstract This paper aims to study the central importance assumed by the derivatives market in the dynamics of contemporary capitalism, focusing in particular on the credit derivatives market and its contribution to the formation and the outbreak of the financial crisis that impacted the U.S. and the world economy in 2007/2008. This dimension is marked by the derivative form, that changes the property relations, introduces new agents and motivations, increases financial integration between the agents and transforms the pricing logic of the major financial markets. Therefore, the paper describes the transformation that the American mortgage market went through,, arguing that such changes gain renewed vigor and are only completed with the rise and growth of credit default swaps (CDS) and synthetic CDOs, that were fundamental to the maintenance of low interest rates on mortgages, thus contributing directly to the bubble in the property market that resulted in the economic crisis.
