title: Does Cystatin C have a role as metabolic surrogate in peritoneal dialysis beyond its association with residual renal function?

description: ABSTRACT Introduction: It has been suggested that cystatin C levels are modified by obesity and inflammation. Furthermore, cystatin C has been associated with cardiovascular events and mortality outcomes. Aim: To study the association of cystatin C with the metabolic profile and cardiovascular disease of peritoneal dialysis patients. Methods: Data collected included clinical, laboratorial, and multifrequency bioimpedance assessment of 52 stable peritoneal dialysis patients. Minimal residual renal function was defined as &gt; 2mL/min/1.73m2. Results: Serum cystatin C was not significantly associated with peritoneal or urinary cystatin C excretion. Negative correlation of cystatin C with normalized protein catabolic rate (rho -0.33, p = 0.02) and a trend towards positive correlation with relative body fat (rho 0.27, p = 0.05) were not independent from residual renal function. Cystatin C was not significantly associated with cardiovascular disease (p = 0.28), nor with glycated hemoglobin (p = 0.19) or c-reactive protein (p = 0.56). In the multivariate model, both age and diabetes were the strongest predictors of cardiovascular disease (odds ratio 1.09, p = 0.029 and odds ratio 29.95, p = 0.016, respectively), while relative body fat was negatively associated with cardiovascular disease (p = 0.038); neither cystatin C (p = 0.096) nor minimal residual renal function (p = 0.756) reached a significant association with cardiovascular disease. Conclusions: In this group of peritoneal dialysis patients, cystatin C did not correlate with the metabolic or inflammatory status, nor cardiovascular disease, after adjustment for residual renal function.

title: A possible relationship between gluconeogenesis and glycogen metabolism in rabbits during myocardial ischemia

description: ABSTRACT Ischemia is responsible for many metabolic abnormalities in the heart, causing changes in organ function. One of modifications occurring in the ischemic cell is changing from aerobic to anaerobic metabolism. This change causes the predominance of the use of carbohydrates as an energy substrate instead of lipids. In this case, the glycogen is essential to the maintenance of heart energy intake, being an important reserve to resist the stress caused by hypoxia, using glycolysis and lactic acid fermentation. In order to study the glucose anaerobic pathways utilization and understand the metabolic adaptations, New Zealand white rabbits were subjected to ischemia caused by Inflow occlusion technique. The animals were monitored during surgery by pH and lactate levels. Transcription analysis of the pyruvate kinase, lactate dehydrogenase and phosphoenolpyruvate carboxykinase enzymes were performed by qRT-PCR, and glycogen quantification was determined enzymatically. Pyruvate kinase transcription increased during ischemia, followed by glycogen consumption content. The gluconeogenesis increased in control and ischemia moments, suggesting a relationship between gluconeogenesis and glycogen metabolism. This result shows the significant contribution of these substrates in the organ energy supply and demonstrates the capacity of the heart to adapt the metabolism after this injury, sustaining the homeostasis during short-term myocardial ischemia.

title: Correlations of condition factor and gonadosomatic, hepatosomatic and lipo-somatic relations of Leptodactylus macrosternum (ANURA: Leptodactylidae) in the Brazilian Semi-arid

description: ABSTRACT The objective of this study was to assess variations of the condition factor (K1) in relation to the gonadosomatic- RGS and energy reserves (hepatosomatic - RWL and liposomatic - RFB relations) of Leptodactylus macrosternum and their relationship to climate variation in the Northeast of Brazil, Caatinga area, state of Paraiba. The animals were captured fortnightly through active collecting, between January and December 2013. Significant differences were observed in the monthly variations of K1, RGS and RFB indices in male and female L. macrosternum over the months of collection. In males, K1 showed no significant relationship with the other variables. In females, RGS values only show notable correlations with RWF and K1 values. K1 values showed significant correlations with all other weight and length ratios. Climate change in the HFOB region showed significant relationships with the variation of the indexes evaluated, with the exception of RWF. The variation of K1, RGS, RWL and RFB values over the months of collection as well as their relation with the local climatic variation, showed a brief reproductive activity for the species.

title: Evidence of Efficacy of Retirement Education Programs: An Experimental Study

description: Abstract This study evaluates the efficacy of three retirement education programs, long, brief and testimony, using an experimental design with a control group and six month follow-up in a sample of public servants (N = 30). We used the scale for behavioral change in retirement planning, subjective well-being and future time perspective and satisfaction questionnaire. Data were analyzed by descriptive, nonparametric statistics and content analysis. There were no statistically significant differences between groups. Effect size analyzes revealed positive effects of long intervention in future time perspective and life satisfaction, as well as positive effects of the control group on occupational-social investment, autonomy and well-being. The evidences are inconclusive about interventions efficacy.

title: Forage potential of native ecotypes of Paspalum notatum and P. guenoarum

description: ABSTRACT The Paspalum genus includes several species that are important for livestock in Rio Grande do Sul, such as P. notatum and P. guenoarum, typical of native pastures of the Pampa biome. The aim of this study was to investigate forage production and chemical composition of four ecotypes of these species in relation to the cv. ‘Pensacola’ (P. notatum). Ecotypes of P. guenoarum (Azulão and Baio) and P. notatum (André da Rocha and Bagual) and the cv. ‘Pensacola’ were evaluated for two years, during which four cuts/year were made. The work was carried out under field conditions at the Agronomic Experimental Station of the Federal University of Rio Grande do Sul (30°05’S; 51°39’W), in a completely randomized design. P. guenoarum stood out for higher productivity and greater tolerance to cold; the Azulão ecotype showed more autumn production in relation to the other ecotypes. Crude protein content ranged from 14 (Baio) to 15% (‘Pensacola’); for neutral detergent fiber, the variation was 68 (Azulão) to 71% (‘Pensacola’) and for acid detergent fiber there was a variation of 38 (‘Pensacola’) to 43% (Baio). The data demonstrates the potential of native genotypes for use as cattle feeding in southern Brazil.

title: Brachial vein transposition: an alternative to hemodialysis arteriovenous graft

description: Abstract Background There is currently a worldwide effort to increase the options for autogenous hemodialysis access. Objectives To evaluate patency and complications of brachial vein transposition compared to other autogenous hemodialysis accesses. Methods A retrospective evaluation of 43 patients and 45 procedures. Patients who did not have adequate superficial veins according to duplex scanning were allocated to brachial vein transposition. The sample was thus divided in two groups, as follows: A: brachial vein transposition n=10 and B: other autogenous accesses n=35. Results There were no statistical differences between the two groups in terms of age diabetes, systemic arterial hypertension, dyslipidemias, arteriopathies, neoplasms, kidney disease stage, donor artery diameter, recipient vein diameter, systolic blood pressure in the operated limb, postoperative ischemia, hematoma, or infection. There were no statistical differences in terms of patency on day 7: A 80% vs. B 90% p=0.6, on day 30: A 80% vs. B 86% p=0.6, or on day 60: A 60% vs. B 80% p=0.22. There were statistical differences between the groups for number of previous fistulae A 1.0 ± 0.44 vs. B 0.6 ± 0.3 p = 0.04 and upper limb edema A: 20% x B 0% p = 0.04. A vein with diameter of less than 3 mm was associated with an increased risk of early occlusion (RR = 8 p = 0.0125). During the study period there were no procedures using grafts. Conclusions Transposition of brachial vein is an alternative to arteriovenous graft.

title: Safety of Antarctic krill (Euphausia superba) as food source: its initial fluoride toxicity study

description: Abstract Antarctic Krill, rich in many nutrients, is supposed to be one of the strategic food sources. However, it is not acceptable for direct consumption as traditional food, as its high content of fluoride is harmful to adults and children. Therefore, the safety of fluoride residue in Antarctic krill for food production should be investigated. In this research, the fluoride toxicity in Antarctic Krill was evaluated through mice feeding experiment. Their body weight was found not to be influenced by fluoride. However, dental fluorosis was observed in the krill group and the NaF group. Fluoride content in liver, kidney, urine, and bones are significantly different (P&lt;0.05) among these three groups, which amount to plateau during the first ten days of feeding, except the fluoride in bone which keeps increasing all through the experimental time. Furthermore, less amount of fluoride was determined in the krill group compared with the amount in NaF group, even if they have the same concentration of fluoride. Besides, lesions in livers, kidneys and bones of the two experimental groups were observed through histopathological studies.

title: Determination of the longitudinal sensitivity of the AVVQ-Brazil Quality of Life Questionnaire to non-surgical treatment of chronic venous disease

description: ABSTRACT Background Sensitivity determines the efficiency and quality of construction of an assessment measure, but studies of the subject are scarce in the literature. Objective To evaluate the longitudinal sensitivity of the AVVQ-Brazil to clinical changes after treatment for chronic venous disease (CVD). Methods A longitudinal intervention study, with 112 chronic venous patients receiving elective treatment, assessed with CEAP, VAPS, AVVQ-Brazil, and VEINES-QOL/Sym at pre-treatment (baseline) and post-treatment (4 weeks). Differences in the scores for the scales at different times were evaluated using Student’s t test for paired samples and Wilcoxon’s z, which were also used to asses individuals by CEAP grade and assessment time. Effect size, confidence intervals, and partial η2 were used to determine the sensitivity of changes in scale scores over time. Correlations between changes in the scores of the same scales and between different scales were measured using Pearson coefficients, Spearman coefficients, and Kendall’s tau-b coefficient. Results The mean age of the patients was 59.51 years. The majority were female (82.1%), with standing for prolonged periods (49.1%), had completed secondary (22.3%) or higher (25%) education, and had CEAP C2 (28.6%) or C6 (32.1%) clinical severity. The following results were observed: mean scale scores reduced from baseline to post-treatment, except for the Extent of Varicosities domain of the AVVQ-Brazil and the VEINES-QOL/Sym scales; sensitivity was low for the AVVQ-Brazil and its domains and for the VAPS, and was from low to high for the other scales; there were improvements or maintenance of CEAP grade after treatment; and moderate to excellent correlations between changes in scale scores over time. Conclusions The AVVQ-Brazil is sensitive to longitudinal clinical changes after treatment for CVD and is an important measure for assessment of QoL and of disease severity in Brazil.

title: INCONSISTENCY AND CORRECTION OF THE GERMAN AMORTIZATION SYSTEM

description: ABSTRACT The amortization systems, also called as amortization methods, are used to compute the installment value that a client must disburse (or spend) to pay off a loan or financing with the number of installments and the interest rate agreed for the loan or financing. This paper shows that the German Amortization System makes an inconsistent use of the interest paid in advance in its definition and generates an effective interest rate higher than the contracted, which makes this system abusive and unfair to the clients. In this article, two forms of correcting the German Amortization System are also proposed, making the effective interest rate equals to the contractual interest rate.

title: Differences in soil electrical resistivity tomography due to soil water contents in an integrated agricultural system

description: Abstract: The objective of this work was to characterize the spatial variability of soil electrical resistivity due to different soil moisture contents, in an integrated agricultural system. Soil electrical resistivity (ER) was measured with the Automatic Resistivity Profiling (ARP) contact sensor in two dates, in 2016, in a 9.7-ha area with different soil moisture contents. The obtained maps indicated that ER allowed delimiting the regions within the study area and pointing out differences in the movement and accumulation of water in the soil horizons. Although there is a trend of reduction in ER values with increasing soil moisture, the spatial correlation structure of ER is similar.
