title: Predictors of readmission and long length of stay in elders admitted with neurological disorders in a tertiary center: a real-world investigation

description: ABSTRACT Hospital readmission and long length of stay (LOS) increase morbidity and hospital mortality and are associated with excessive costs to health systems. Objective: This study aimed to identify predictors of hospital readmission and long LOS among elders with neurological disorders (NDs). Methods: Patients ≥ 60 years of age admitted to the hospital between January 1, 2009, and December 31, 2010, with acute NDs, chronic NDs as underpinnings of acute clinical disorders, and neurological complications of other diseases were studied. We analyzed demographic factors, NDs, and comorbidities as independent predictors of readmission and long LOS (≥ 9 days). Logistic regression was performed for multivariate analysis. Results: Overall, 1,154 NDs and 2,679 comorbidities were identified among 798 inpatients aged ≥ 60 years (mean 75.8 ± 9.1). Of the patients, 54.5% were female. Patient readmissions were 251(31%) and 409 patients (51%) had an LOS ≥ 9 days (95% confidence interval 48%–55%). We found no predictors for readmission. Low socioeconomic class (p = 0.001), respiratory disorder (p &lt; 0.001), infection (p &lt; 0.001), genitourinary disorder (p &lt; 0.033), and arterial hypertension (p = 0.002) were predictors of long LOS. Identified risks of long LOS explained 22% of predictors. Conclusions: Identifying risk factors for patient readmission are challenges for neurology teams and health system stakeholders. As low socioeconomic class and four comorbidities, but no NDs, were identified as predictors for long LOS, we recommend studying patient multimorbidity as well as functional and cognitive scores to determine whether they improve the risk model of long LOS in this population.

title: In vitro assessment of the probiotic potential of lactobacilli isolated from Minas artisanal cheese produced in the Araxá region, Minas Gerais state, Brazil

description: ABSTRACT Minas artisanal cheese is made from endogenous starter cultures, including lactic acid bacteria (LAB). Some LAB may possess probiotic potential. Thus, this study aimed to evaluate the in vitro probiotic properties of lactobacilli isolated from Minas artisanal cheeses produced in Minas Gerais. Ten samples of lactobacilli, formerly isolated from those cheeses, were submitted to the following assays: antimicrobial susceptibility, tolerance to artificial gastric juice and biliary salts, production of hydrogen peroxide and antagonism against pathogenic and non-pathogenic micro-organisms. Only L. plantarum (C0) was sensitive to all tested antimicrobials, while the other LAB samples were resistant to at least one drug. Six samples were tolerant to artificial gastric juice, and L. brevis (A6) even grew in that medium. Three samples were tolerant to biliary salts. Only L. brevis (E35) produced hydrogen peroxide. Difference (P&lt; 0.05) was observed among the means of inhibition haloes of lactobacilli against Enterococcus faecalis ATCC 19433 and Lactobacillus plantarum C24 in spot-on-the-lawn assay. All samples of lactobacilli inhibited Escherichia coli ATCC 25922, Salmonella enterica var. Typhimurium ATCC 14028 in co-culture antagonism test (P&lt; 0.0001). Most lactobacilli samples showed in vitro probiotic potential. From the tested samples, L. brevis (A6) presented the best results considering all in vitro probiotic tests.

title: Changes in Cardiac Autonomic Modulation in Women with Breast Cancer Using Aromatase Inhibitors and the Relation with Biochemical Variables

description: Abstract Background: The use of autonomic modulation as a predictor of cardiovascular risk in women with breast cancer is important. Objective: To evaluate the cardiac autonomic modulation of postmenopausal women using aromatase inhibitors for breast cancer treatment, as well as its relation with the following biochemical variables. Methods: Postmenopausal women who did not have breast cancer (n = 33) and postmenopausal women with breast cancer (n = 15). For evaluation of the autonomic modulation the heart rate was recorded beat-to-beat for 30 minutes and the series of RR intervals obtained were used to calculate the following heart rate variability indices: Mean RR ms, SDNN (standard deviation of all normal RR intervals, expressed in milliseconds) ms, Mean HR, RMSSD (square root of the mean of the squared differences between adjacent normal RR interval) ms, NN50 (number of pairs of successive NNs that differ by more than 50 ms) count, pNN50% (proportion of NN50 divided by total number of NNs), RRtri (RR triangular), TINN (triangular interpolation of NN interval) ms, SD1 ms, SD2 ms, LF ms2, HF ms2, LH/HF ms2. The values of biochemical variables (fasting glycemia, triglycerides, HDL-cholesterol, and C-reactive protein) were analyzed by blood sample. Results: Lower values of heart rate variability indices were observed in postmenopausal women with breast cancer in relation to postmenopausal women who did not have breast cancer: Mean RR (p = 0.03); SDNN (p = 0.03); RMSSD (p = 0.03); NN50 count (p = 0.03); pNN50 % (p = 0.03); RRtri (p = 0.02); SD1 (p = 0.01); SD2 (p = 0.02); LF ms2 (p = 0.01); HF ms2 (p = 0.03).There was an inversely proportional correlation between the indices SDNN, SD2, and HFms2 with triglycerides (SDNN p = 0.04; SD2 p = 0.04; HF ms2 p = 0.04). No statistically significant correlations were found between heart rate variability indices and others variables. Statistical significance was set at 5% for all analyses. Conclusion: Women with breast cancer present reduced autonomic modulation and in these women of heart rate variability indices are inversely correlated with triglyceride values.

title: Estudo sobre o impacto da hibridização de fibras em propriedades materiais de compósitos cemenciosos engenhados

description: ABSTRACT Engineered Cementitious Composite (ECC) is a type of improved high-performance fiber reinforced ce-mentitious composites with good tensile, compression and flexural behavior. ECC is known for their strain-hardening behavior under tension and has been increasingly applied in engineering practice. The process of adding two or more fibers in a mix is known as hybridization. The hybrid composite drives benefits from each of the individual fibers added and exhibits improved ultimate strength and strain capacity compared to the mono-fiber composites. The major applications of ECC are structural reinforcement in the construction and also organic fiber hybridization is valid only for underwater conditions and they will provide additional tests concerning burnability or flammability. This work presents the results obtained from three ECC mixes (PVA, PP, STEEL) and four Hybrid Engineered Cementitious Composites (HECC) with different combinations of volume fraction with PVA, PP, STEEL. The experimental studies have been carried out to investigate the mechanical behaviors of ECC and HECC. The results indicate that this hybridation process has a notable achievement in compressive strength, direct tensile strength and flexural strength.

title: The sector elasticities of Brazilian exports: an empirical analysis for the period 1999-2013

description: Abstract The objective of this study is to analyze the performance of Brazilian exports of primary commodities and manufactures for the Asian, NAFTA, European Union and MERCOSUR countries between 1999 and 2013. From an extension of the Imperfect Substitutes Model, elaborated by Goldstein and Khan (1978), the Error Correction Model (ECM) was used to determine the short- and long-term elasticities. The results show that in the trade with these blocks of countries, commodities are more sensitive to external income than to other variables considered in this study. As for manufactures, the results also point to a greater influence of the variable income, except for the block of Asian countries, where the variable relative price seems to be the most important determinant and that exports of manufactured goods are more sensitive to changes in the exchange rate than exports of primary commodities.

title: Characterization of tolerance to citrus leafminer of Citrus and related genera

description: ABSTRACT The aim of this study was to identify resistance of tolerance type in Citrus and Poncirus genotypes towards the citrus leafminer (CLM), Phyllocnistis citrella. The quantitative variables leaf and shoot lengths, leaf width, number of larvae and new shoots, and fresh and dry shoots weights, and qualitative variables associated with foliar damage were evaluated in six Citrus-related genotypes infested with CLM. In preliminary trials with lime Rough lemon (C. jambhiri), the variables that best discriminated the infestation effect of CLM were established as the numbers of larvae and new shoots per plant together with the percentages of partially rolled leaves (PRL), rolled leaves (RL) and total damage (TD = RL + PRL). In subsequent tests with all six genotypes, the variables new shoots per plant, percentage of attacked but not rolled leaves (ANRL), RL and TD were found to be significant. Trifoliata Limeira (P. trifoliata) and hybrid C × R4 (C. sunki × P. trifoliata) presented the lowest percentages of RL and TD and the highest values of ANRL. A cluster analysis was performed considering all the variables analyzed and the most tolerant genotypes for CLM, namely hybridsC × R4, C × R315 (C. sunki × P. trifoliata), M × P222 [C. sinensis × Tangor Murcott (C. reticulata × C. sinensis)] and Trifoliata Limeira (P. trifoliata) were grouped apart from the less tolerant genotypes Sunki mandarin (C. sunki) and lime Rough lemon. In conclusion, genotypes Trifoliata Limeira and its hybrid C × R4 are the most tolerant to CLM.

title: Sampling of cashew nuts as an aid to research for the genetic improvement of cashew tree

description: Abstract: The objective of this work was to estimate sample sizes of cashew (Anacardium occidentale) nuts as an aid to the genetic improvement of cashew tree. Nuts were separated by size: nuts &lt; 17 mm were classified as size 1 (S1); 17 mm ≤ nuts &lt; 19 mm, size 2 (S2); 19 mm ≤ nuts &lt; 23 mm, size 3 (S3); 23 mm ≤ nuts &lt; 25 mm, size 4 (S4); and nuts ≥ 25 mm, size 5 (S5). Sizing the sample for each stratum depends on the variance of nut size and on the error level B allowed for either the estimates or the desired precision in the results. The sample size will be larger the greater the variance of the stratum, the lower the error level allowed for the estimates, or the greater the precision desired in the results. For an error B = 0.2 g, the sample sizes of the S5, S4, and S3 strata were n5 = 42 nuts, n4 = 30 nuts, and n3 = 19 nuts, respectively. In the S5 and S4 strata, with better nut classifications, the average weight was 12.71 and 9.76 g, respectively. The Sm stratum - formed by the mixture of nuts of several sizes - should not be used as a parameter in this context due to its great variability, which is far larger than that of the other strata. Stratified sampling composed of six strata (S1, S2, ..., S5, Sm) is effective for estimating different sizes of nut samples.

title: Occurrence of anti-Leishmania spp antibodies in felines in an endemic area of the State of São Paulo

description: ABSTRACT Visceral leishmaniasis (VL) is a zoonosis with a great impact on public health. Infection in cats has been reported in countries where the disease is endemic. Its role as reservoir is not satisfactorily elucidated, although transmission of the parasite from an infected feline to vector has been reported by xenodiagnosis. The objective of this study was to evaluate the presence of anti-Leishmania spp antibodies in feline animals in an area endemic to LV (Bauru-SP), using the serological tests of Indirect Immunofluorescence Reaction (IFR) and ELISA and variables: gender, age, race and form of creation. Samples of 276 felines were tested, of which 82 were ELISA reagents (29,71%), 17 by IFR (6,15%) and 10 in both tests (3,6%). There was a significant statistical association for the variable form of breeding, where 100% of the wandering animals were seropositive to at least one of the tests (P &lt;0,005). Such association was not found for the other variables analyzed (P &gt;0,05). There was no concordance between the results of the tests, since the ELISA method is more sensitive than the RIFI method.

title: Mechanical behavior of clay soil stabilizedwith glass residue powdered in high-energy and ball mills

description: ABSTRACT The capital of the Amazonas State presents difficulties in the construction of pavements due to the superficial predominance of clay in its geotechnical profile. This material is unsuitable for the construction of sublayers of these urban structures. In the present study, the mechanical behavior of the Manaus-AM typical clay soil was evaluated in its natural condition and when mixed with 5% of powdered glass waste processed in two types of mills (balls and high energy) in order to improve their geotechnical properties. The natural material and its compositions was characterized in relation to their physical properties (liquidity limit, plasticity limit, grain size and compaction) and mineralogical properties, as well as the natural soil mineralogy. According to the direct shear test and the Coulomb rupture criterion, the cohesion and the internal friction angle of the clay soil were determined, as well of the soil compositions with 5% of powdered glass processed in ball mill and 5% of powdered glass processed in high-energy mill. The results showed that there was a significant improvement in the regional soil properties when glass residue is added, both physically and mechanically, with emphasis on the participation of the powdered material processed in the high-energy mill. Therefore, the powdered glass has the potential to be used as granulometric stabilizer in roadways construction, which is an environmental alternative for the disposal of such materials.
