<p>Este trabalho teve por objetivo avaliar o desenvolvimento de clones de <em>Pyrostegia venusta </em>em diferentes tipos de substratos. O experimento foi conduzido em delineamento inteiramente casualizado, com 06 tratamentos e 10 repetições, cada repetição foi constituída por um tubete de polietileno com capacidade de 103cm<sup>3</sup>. Os tratamentos testados foram: (T1) 100% de areia lavada; (T2) 50% areia lavada + 50% substrato comercial Plantmax®; (T3) 100% de substrato comercial Plantmax®; (T4) 50% areia lavada + 50% de esterco bovino; (T5) 1/3 areia lavada + 1/3 esterco bovino +1/3 de Plantmax® e (T6) 50% esterco bovino + 50% de Areia lavada. Após 30 dias foram avaliados o número de estacas sobreviventes, comprimento do broto (cm), número de folhas, comprimento da folha (cm), número de raízes e comprimento da raiz principal (cm). Os dados foram submetidos a análise de variância e as médias comparadas pelo teste de Tukey a 5% de probabilidade. Por meio da análise de variância (p&lt;0,01), detectou-se significância estatística, para as variáveis, sobrevivência das estacas e número de brotos por estaca de <em>P. venusta</em>, quando cultivadas em substrato composto por 50% areia lavada + 50% substrato comercial Plantmax®. Essa mistura apresenta a vantagem de ser mais econômica quando comparado ao substrato comercial Plantmax®, sendo portanto, recomendada na produção de mudas de <em>cipó-de-São João</em><em>.</em></p><p align="center"><strong><em>Utilization of different substrates in the propagation of Pyrostegia venusta by cuttings</em></strong></p><p><strong>Abstract</strong><strong>: </strong>The experiment was carried out in a completely randomized design with 06 treatments and 10 replicates, each replicate consisted of polyethylene plastic tube the size of 103cm<sup>3</sup>.

O feijão-caupi (Vigna unguiculata L. Walp), é uma leguminosa herbácea, considerada principal fonte protéica vegetal para famílias de baixa renda no Brasil. Cultivado em regiões de clima quente úmido e semiárido, torna-se uma opção para a região nordeste, uma vez que pode servir como alternativa de fonte de renda aos pequenos e médios produtores. Nesse sentido, objetivou-se avaliar as características produtivas de genótipos de feijão-caupi irrigados com água salina. Os tratamentos consistiam da combinação de dois fatores: Salinidade da água de irrigação (A1 - água de abastecimento com 0,8dSm-1 e A2 - solução salina 4,8 dSm-1) e Genótipos de feijão-caupi (G1 - MNC04-762F-9, G2 - MNC04-762F-3, G3 - MNC04-762F-21, G4 - MNC04-769F-62 e G5 - MNC04-765F-153). Combinados os fatores, no delineamento inteiramente casualizado, resultaram em 10 tratamentos (2 níveis de salinidade x 5 genótipos), com 4 repetições. A irrigação com água salina se deu aos 12 DAS. As variáveis analisadas foram o número de vagens por planta (NVP), comprimento da vagem por planta (CVP), número de grãos por vagem (NGV), número de grãos por planta (NGP) e peso dos grãos por planta (PGP). A salinidade da água de irrigação reduziu consideravelmente as características produtivas de genótipos de feijão-caupi.Production components of bean-cowpea genotypes irrigated with saline waterAbstract: Cowpea (Vigna unguiculata L. Walp) is a herbaceous legume, considered main vegetable protein source for low-income families in Brazil. Grown in hot humid climates and semi-arid, it becomes an option for the northeast region, since it can serve as an alternative income source to small and medium producers. In this sense, the objective was to evaluate the production characteristics of cowpea genotypes irrigated with saline water. The treatments consisted of the combination of two factors: Irrigation Water Salinity (A1 - water supply with 0,8dSm-1 and A2 – saline solution 4.8 dSm-1) and cowpea genotypes (G1 - MNC04-762F -9, G2 - MNC04-762F-3 G3 - MNC04-762F-21 G4 - G5 and MNC04-769F-62 - MNC04-765F-153). Combined factors, a completely randomized design, resulted in 10 treatments (2 levels of salinity x 5 genotypes) with four repetitions. The irrigation with saline water given to the 12 days after sowing (DAS). The variables were the number of pods per plant (NP), pod length per plant (PL), number of seeds per pod (SP), number of grains per plant (GP) and weight of grains per plant (WGP). The salinity of the irrigation water significantly reduced the productive characteristics of cowpea genotypes.

Background Recent investigations indicated that nonalcoholic fatty liver disease (NAFLD), a hepatic component of metabolic syndrome (MS), is associated with an increased risk of cardiovascular disease (CVD). Accordingly, we were interested in exploring the frequency of NAFLD in peritoneal dialysis (PD) patients and analyzing factors in PD patients associated with NAFLD occurrence. In addition, we were interested in investigating whether NAFLD is associated with higher CVD risk in our PD patients. Methods In the present cross-sectional study, we analyzed 58 PD patients. The controlled attenuation parameter (CAP) was used to detect and quantify liver steatosis with the help of transient elastography (TE) (FibroScan, Echosense SA, Paris, France). A carotid ultrasound was performed in all patients to measure carotid intimae media thickness (IMT) and plaque as surrogate measures of increased CVD risk, and we investigated their association with NAFLD. Results Nonalcoholic fatty liver disease was present in 74.1% of PD patients. Peritoneal dialysis/nonalcoholic fatty liver disease patients had statistically greater daily (136.5 ± 62.6 vs 93.6 ± 36.1; p = 0.02) and monthly (4,095.3 ± 1,877.7 vs 2,806.6 ± 1,083.2; p = 0.02) glucose load in comparison to the non-NAFLD/PD patients. In the next step, we were interested in analyzing what demographic and clinical characteristics in our PD patients are associated with a higher NAFLD occurrence. Presence of diabetes mellitus (DM), arterial hypertension (AH), dyslipidemia, body mass index > 25 kg/m2, and daily glucose load > 100 g were associated with NAFLD occurrence. Peritoneal dialysis patients with NAFLD showed more carotid atherosclerosis than PD patients without NAFLD. In addition, CAP values (as indicator of liver steatosis) showed strong positive association with IMT (r = 0.801; p < 0.0001). Nonalcoholic fatty liver disease was a strong predictor of carotid atherosclerosis in PD patients. Conclusion Nonalcoholic fatty liver disease is highly prevalent in PD patients. Peritoneal dialysis patients with NAFLD are at high risk of atherosclerosis. Assessment of NAFLD in PD patients may be helpful for CVD risk stratification.

Background Biocompatible fluids for peritoneal dialysis (PD) have been introduced to improve dialysis and patient outcome in end-stage renal disease. However, their impact on hydration status (HS), residual renal function (RRF), and dialysis adequacy has been a matter of debate. The aim of the study was to evaluate the influence of a biocompatible dialysis fluid on the HS of prevalent PD patients. Methods The study population consisted of 18 prevalent PD subjects, treated with standard dialysis fluids. At baseline, 9 patients were switched to a biocompatible solution, low in glucose degradation products (GDPs) (Balance; Fresenius Medical Care, Bad Homburg, Germany). Hydration status was assessed through clinical evaluation, laboratory parameters, echocardiography, and bioimpedance spectroscopy over a 24-month observation period. Results During the study period, urine volume decreased similarly in both groups. At the end of the evaluation, there were also no differences in clinical (body weight, edema, blood pressure), laboratory (N-terminal pro-brain natriuretic peptide, NTproBNP), or echocardiography determinants of HS. However, dialysis ultra-filtration decreased in the low-GDP group and, at the end of the study, equaled 929 ± 404 mL, compared with 1,317 ± 363 mL in the standard-fluid subjects ( p = 0.06). Hydration status assessed by bioimpedance spectroscopy was +3.64 ± 2.08 L in the low-GDP patients and +1.47 ± 1.61 L in the controls ( p = 0.03). Conclusions The use of a low-GDP biocompatible dialysis fluid was associated with a tendency to overhydration, probably due to diminished ultrafiltration in prevalent PD patients.

Background Although higher body mass index (BMI) is associated with better outcomes in hemodialysis patients, the relationship in peritoneal dialysis (PD) patients is less clear. We aimed to synthesize the results from all large and high-quality studies to examine whether underweight, overweight, or obesity is associated with any significantly different risk of death in peritoneal dialysis patients. Methods We searched MEDLINE, EMBASE, Web of Science, CINAHL, and Cochrane CENTRAL, and screened 7,123 retrieved studies for inclusion. Two investigators independently selected the studies using predefined criteria and assessed each study's quality using the Newcastle-Ottawa Quality Assessment Scale. We meta-analyzed the results of the largest studies with no overlap in their data sources. Results We included 9 studies ( n = 156,562) in the systematic review and 4 studies in the meta-analyses. When examined without stratifying studies by follow-up duration, the results of the studies were inconsistent. Hence, we pooled the study results stratified based upon their follow-up durations, as suggested by a large study, and observed that being underweight was associated with higher 1-year mortality but had no significant association with 2- and 3- to 5-year mortalities. In contrast, being overweight or obese was associated with lower 1-year mortality but it had no significant association with 2-, and 3- to 5-year mortalities. Conclusion Over the short-term, being underweight was associated with higher mortality and being overweight or obese was associated with lower mortality. The associations of body mass with mortality were not significant over the long-term.
