title: APPLICABILITY OF A GENERIC QUESTIONNAIRE FOR QUALITY OF LIFE ASSESSMENT FOR ASTHMATIC CHILDREN

description: ABSTRACT Objective: To determine the applicability of the generic instrument Pediatric Quality of Life Inventory (PedsQL 4.0) to assess health-related quality of life of asthmatic children compared to the specific instrument Pediatric Asthma Quality of Life Questionnaire (PAQLQ). Methods: This research involved the evaluation of 30 children aged seven to eleven years, who had been diagnosed with asthma for at least six months prior to research. Both quality of life questionnaires were applied to children by an interviewer over the period of one day. Data were analyzed using the Statistical Package for the Social Sciences (SPSS) 20.0, with significance level set at 5%. Results: No differences in quality of life was found when genders were compared. Asthmatic children classified as practitioners and non-practitioners of physical activity had different scores in the physical health-related domain (PedsQL 4.0). The scores of children with different levels of asthma severity and control were significantly different in two out of three domains evaluated by PAQLQ. When assessed by PedsQL 4.0, no significant difference was observed as to quality of life of children with different levels of asthma control and severity. Quality of life measurements of asthmatic children by PedsQL 4.0 and PAQLQ instruments had a moderate and significant correlation (r=0.415, p=0.02). Conclusions: PedsQL 4.0 could distinguish children practicing different levels of physical activity, but it was not sensitive enough to distinguish health-related quality of life among children with different levels of asthma severity and control.

title: External Validation of European System for Cardiac Operative Risk Evaluation II (EuroSCORE II) for Risk Prioritization in an Iranian Population

description: Abstract Introduction: The European System for Cardiac Operative Risk Evaluation II (EuroSCORE II) is a prediction model which maps 18 predictors to a 30-day post-operative risk of death concentrating on accurate stratification of candidate patients for cardiac surgery. Objective: The objective of this study was to determine the performance of the EuroSCORE II risk-analysis predictions among patients who underwent heart surgeries in one area of Iran. Methods: A retrospective cohort study was conducted to collect the required variables for all consecutive patients who underwent heart surgeries at Emam Reza hospital, Northeast Iran between 2014 and 2015. Univariate and multivariate analysis were performed to identify covariates which significantly contribute to higher EuroSCORE II in our population. External validation was performed by comparing the real and expected mortality using area under the receiver operating characteristic curve (AUC) for discrimination assessment. Also, Brier Score and Hosmer-Lemeshow goodness-of-fit test were used to show the overall performance and calibration level, respectively. Results: Two thousand five hundred eight one (59.6% males) were included. The observed mortality rate was 3.3%, but EuroSCORE II had a prediction of 4.7%. Although the overall performance was acceptable (Brier score=0.047), the model showed poor discriminatory power by AUC=0.667 (sensitivity=61.90, and specificity=66.24) and calibration (Hosmer-Lemeshow test, P&lt;0.01). Conclusion: Our study showed that the EuroSCORE II discrimination power is less than optimal for outcome prediction and less accurate for resource allocation programs. It highlights the need for recalibration of this risk stratification tool aiming to improve post cardiac surgery outcome predictions in Iran.

title: SURFACE RUNOFF OF RAINFALL IN AN EXPERIMENTAL PLANTATION OF MACAÚBA PALM (Acrocomia aculeata) UNDER DIFFERENT FORMS OF MANAGEMENT

description: ABSTRACT Several studies have been conducted aiming to explore the commercial potential of the macaúba palm. However, research on the hydrological processes of this crop are scarce. Thus, we aimed to quantify the surface runoff in a macaúba plantation subjected to different crop management techniques, from September 2012 toAugust 2013. We established 10 plots for surface runoff quantification; each plot had a 63-m² area, was delimited by metallic foils and had a gallon to collect runoff water at its outlet. Plots consisted of three treatments and three repetitions, plus one control plot, each having four macaúba plants. Treatments were as follows: treatment one (T1) - with no soil conservation technique being implemented; treatment two (T2) - with a narrow-base terrace 40 cm wide and 30 cm deep; treatment three (T3) - with bean being planted during the rainy months, forming vegetation strips; and control treatment (T0) - with no macaúba plants, with spontaneous vegetation growing throughout the entire plot and with no soil conservation technique being implemented. Surface runoff differed among treatments. T2 was the treatment with lowest runoff and also the one that demanded the highest precipitation volume for surface runoff to occur. Our results indicate that both the cover and the use of soil conservation techniques are closely related to surface runoff, which in turn affects the occurrence of erosion and infiltration.

title: CABG and Preoperative use of Beta-Blockers in Patients with Stable Angina are Associated with Better Cardiovascular Survival

description: Abstract Objective: In contrast to unstable angina, optimal therapy in patients with stable angina is debated. Our aim was to evaluate the outcomes of patients with stable angina scheduled for isolated coronary artery bypass grafts and the effect of preoperative use of beta-blockers. Overall and cardiovascular survivals were our primary outcome. Operative mortality and postoperative complications along with subgroup analysis of diabetic patients were our secondary outcomes. Methods: Retrospective evaluation of patients with stable angina scheduled for isolated coronary artery bypass grafts was included. Pre- and postoperative variables were extracted from the institution database. Survival was obtained from the National Registry. Results: We included 282 patients with stable angina, with a mean age of 65.6±9.5 years. 26.6% were female and 38.7% had diabetes. Three-vessel disease was present in 76.6% of patients. Previous beta-blocker treatment was evident in 69.9% of patients. 10-year overall survival in the whole population was 60.5% (95% confidence interval [CI]: 50.3-70.7%). Operative mortality during the study period was 3.5%. Patients with preoperative use of beta-blocker therapy had better overall survival (9.0 years, 95%CI: 8.6-9.5) than those without treatment (7.9 years, 95%CI: 7.1-8.8 years; P=0.048). Predictors for overall survival were: hypertension, diabetes, and age. Predictors for cardiovascular survival in diabetic patients were: beta-blocker use, gender, and age. Conclusion: Coronary artery bypass grafts surgery in patients with stable angina carries low operative mortality, postoperative complications, and excellent long-term cardiovascular survival. The preoperative use of beta-blockers in diabetic patients is associated with better cardiovascular survival after coronary artery bypass grafts.

title: Optimization of structural brickwork laying joints in concrete blocks

description: Abstract One of the challenges in the investigation of structural masonry is the correlation between the thickness of the laying joints and the global resistance of the masonry. Many authors developed experimental correlations in the attempt to establish an analytical relation between the joint thickness and the resistance of the masonry. All these projects indicate that there are many parameters and considerations to be analyzed in the understanding this relation and in understanding the collapse of the masonry as a whole. Thus, in an attempt to contribute with this field of study, the present paper investigates the influence of the thickness of the mortar laying joint in the resistance of the masonry structure. With the objective of experimentally establishing a relation between the joint thickness and the resistance of the masonry, rupture trials were held to the axial compression of three block prisms laid with five series of thicknesses: 8mm, 12.5mm, 10mm, 15mm and 20mm. The physical and mechanic description of all the components that made up the masonry were done separately, complying with the regulations. Through a simplified statistical analyses, presented at the end of this study, values of resistance of each series of prisms associated to a specific thickness for the laying joint are shown. Through the comparison of the specific results of the analyzed specimen, we arrived at the suggestion of a better performance joint and it was also possible to establish a behavioral tendency, through the comparison of results, helping in the understanding of how the block-joint set behave monolithically from the determination of the individual characteristics of each element. Which is one of the keys that will permit the constructions of a behavioral model capable of assisting structural analysts in their structural masonry dimensioning techniques.

title: Assessment of flatulence causing agents in Chickpea (Cicer arietinum L.) and their possible removal

description: Abstract Flatulence and fullness of stomach is one of the most common problem associated with chickpea primary due to presence of some oligosaccharides and phenols. In this investigation Desi and Kabuli varieties were compared for these oligosaccharides and phenolic compounds. Furthermore, the effect of different processing and cooking methods such as soaking, cooking and germination in the reduction of these antiphysiological factors were are also studies. Maximum tannic acid (0.90 ± 0.20%) was observed in Parbat and C-44 while minimum (0.60 ± 0.04%) in Karak-2. Stachyose contents ranged between 1.10 ± 0.05 (Karak-3) to 1.42 ± 0.02% (Parbat) while raffinose was 0.63 ± 0.05(Karak-3) to 0.81 ± 0.02% (Dasht). The highest tannic acid content was reduced up to 50% in C-44 by cooking of 72 hours germinated seeds. Stachyose and raffinose contents were completely removed after 72 hours germination. Present studies revealed that cooking after germination is the most effective method to reduce the anti-nutritional factors of chickpea. Individually, soaking and cooking also contributed to the loss of the same factors but to a lesser extent.

title: Metal-Resistant Rhizobacteria Change Soluble-Exchangeable Fraction in Multi-Metal-Contaminated Soil Samples

description: ABSTRACT There is a complex interaction between various components of the soil ecosystem, including microbial biomass and soil chemical contaminants such as heavy metals and radionuclides, which may greatly affect the efficiency of bioremediation techniques. The aim of this study was to investigate microbial capacity to change pH, changes in the metal soluble-exchangeable fraction, and effects of initial heavy metal contents on soil samples in microbial solubilization/immobilization capacity. The soil samples used in this study were collected at a known metal-contaminated site. Three highly metal-resistant bacteria were isolated from rhizosphere soil samples collected on weed species identified as Senecio brasiliensis, Senecio leptolobus, and Baccharis trimera. A completely randomized experimental design in a factorial arrangement was used, with three replicates. In general, with an acid pH, the isolates neutralized the contaminated growth media. In a neutral or basic initial pH, increases in pH were observed in the media, so these bacteria have an alkalizing effect on the growth media. Soluble metal contents were quite different and depend on the microbial species and heavy metal contents in the soil samples. The soluble-exchangeable fraction of metal such as Cu, Zn, Ni, Cr, Cd, Pb, and Ba may be unavailable after inoculation with heavy metalresistant rhizobacteria. A promising approach seems to be the application of inoculants with metal-resistant bacteria in bioremediation of multi-metal-polluted environments to improve the efficiency of this environmentally friendly technology.
