title: Use of artificial sweeteners in Brazil: a household survey approach

description: Abstract: The objective was to estimate the prevalence of artificial sweetener use by the adult Brazilian population and users’ characteristics. Analysis of data from the Brazilian National Survey on Access, Utilization, and Promotion of Rational Use of Medicines (PNAUM, 2014), a nationwide population-based survey. The target outcome was self-reported use of sweeteners by Brazilians 20 years and older. The independent variables were sex, age, major geographic region of Brazil, schooling in complete years, and economic status according to the Brazilian Economic Classification Criterion of the Brazilian Association of Research Companies (ABEP). The health condition indicators were: self-reported noncommunicable diseases (NCDs), number of NCDs, and body mass index (BMI). Prevalence of sweetener use in the Brazilian adult population was 13.4% (95%CI: 12.5-14.3), and it was higher in females and in persons 60 years or older, in the Northeast and Southeast, among individuals from economic classes A and B, and among obese individuals. Persons with chronic diseases (especially diabetes) showed the highest prevalence of use of sweeteners, and their use increased with the number of reported comorbidities. Prevalence of use of artificial sweeteners was 13.4% and was associated with sociodemographic and health characteristics.

title: Malting of preharvest sprouted wheat

description: ABSTRACT Pre-harvest sprouting is one of the most important problems of the wheat crop and it is necessary to find alternative uses for the grain because millers reject the damaged wheat. In the field these grains were stimulated to germinate, due to weather conditions and their metabolic activity was enhanced, the hydrolytic enzymes promoted changes in the proteins and reserve carbohydrates, which reflect on the flour quality. Similar to malting germination has started, but with different intensity and under different conditions. There are some studies about malting of sprouted barley and the malting of rain-damaged wheat could be a possibility worth investigation. The objective of this work was to evaluate the malting of pre-harvest sprouted wheat samples. Four wheat samples were characterized by falling number and germination power; and three of them that were considered sprouted. A randomized standard experimental design was applied and the malting conditions were: moisture content 43%, germination time 78 hours, and germination temperature 12.5 ºC. Malt quality parameters determined were: malting losses, extract, limit attenuation, viscosity, total protein, soluble protein, Kolbach index, alfa and beta-amylase. The malting process resulted in increased soluble protein, FAN, Kolbach index and α-amylase activity, but decreased β-amylase activity for all rain damaged samples. There was no difference among the rain damaged samples for FAN, Kolbach index, α and β-amylase activity, extract, apparent attenuation limit and viscosity. A sound sample malted had higher α and β-amylase activity, extract, and the lowest soluble protein content.

title: Powdered beverage mix with acerola pulp, whey and maltodextrin

description: ABSTRACT Mixing acerola pulp with whey, a by-product of the dairy industry, led to this study, whose aim was the development of a powdered beverage mix of acerola pulp, whey and maltodextrin (DE20). To determine the proportions of the mixture, a simplex-centroid mixture design was used. Different proportions of the mixture were dehydrated in a spray dryer at 175 °C. The results were evaluated in relation to hygroscopicity, moisture and ascorbic acid. Higher proportions of whey and pulp increased hygroscopicity and moisture, while maltodextrin reduced these parameters. An increase in pulp content raised the levels of ascorbic acid. The proportions (m m-1) of 50% acerola pulp, 25% whey and 25% maltodextrin resulted in significantly lower hygroscopicity (8.25 g 100 g-1) and moisture (1.66%), and appreciable levels of ascorbic acid (1492.49 g 100 g-1). The results indicated that the powder obtained shows good stability after 75 days of storage, with 9.20%, 1.79% and 1146.13 g 100 g-1 of hygroscopicity, moisture and ascorbic acid respectively.

title: Extraction and analysis of the parietal polysaccharides of acorn pericarps from Quercus trees

description: Abstract Acorns produced by Quercus trees are currently underexploited and undervalued. To evaluate the commercial and health benefits of acorns, we examined the cell wall components of acorn pericarps from Quercus suber and Quercus ilex, growing in North-Western Algeria. Acorn pericarps were sequentially extracted and the polysaccharide fractions were analyzed by gas liquid chromatography and Fourier-transform infrared spectroscopy. The lignocellulosic fraction was the major component of Q. suber and Q. ilex cell walls (37.19% and 48.95%, respectively). Lower amounts of pectins and hemicelluloses were also found in both species. Hemicellulose extracts from the two species contained xylose as the major monosaccharide (ranging from 36.7% to 49.4%). Galacturonic acid was the major component of hot water- or ammonium oxalate-extracted pectins from both species (ranging from 20.6% to 46.8%). The results reported in this paper reveal that acorn pericarp cell walls from these two oak could be potential sources of bioactive compounds.

title: SEASONAL DYNAMICS OF AGRICULTURAL SOIL COVER IN RUNOFF GENERATION

description: ABSTRACT Seasonal changes in agricultural soil use due to agroclimatic conditions affect the water cycle in watersheds. This study aimed to understand the temporal variation of runoff inherent to the seasonal occupation dynamics of the agricultural soil in the basin that drains the upper valley of the Marrecas River, upstream of the urban perimeter of Francisco Beltrão, PR. The effects of runoff were verified through flow peaks simulated by the HEC-HMS model in twelve monthly soil use scenarios, under seven precipitation return periods. The results indicated a strong relationship between bare soil and flow peaks, temporally delimiting April and March as the largest runoff generators and January and August as the smallest ones. The ratio quantified by rates of increase in flow peaks ranging from 0.78 to 1.64 m3 s−1 per km2 of bare soil. In addition, the survey of historical precipitation data also warns of the generation of large runoff volumes in October. Therefore, the strong correlation between the increase in flow peaks and occupation by bare soil can be quantified with good precision, but it is also necessary to consider historical precipitation records to understand the temporal distribution of runoff and flood risks.

title: How much do we know about the groundwater quality and its impact on Brazilian society today?

description: Abstract Groundwater is an essential resource for society and the environment in Brazil. More than 557 m3/s (17.5 km3/y) are extracted through 2.5 million wells to meet demand in cities and the countryside, generating an economy of R$ 56 billion per year (US$ 14 billion/year). The aquifer has a remarkable function in the hydrological cycle because its large storage regulates the perenniality of rivers, lakes and preserves mangroves, marshes, and vegetation in dry periods. Aquifer discharges maintain between 24% (annual average) and 49% (dry season) of the flow of these surface water bodies. Although studies on groundwater quality are still restricted, it is known that most aquifers still preserve their excellent natural quality. Nevertheless, over the past years, there has been a growing increase in cases of contamination associated with: (i) natural geochemical anomalies (iron, manganese, and fluorine, secondarily, chromium, and barium, and rarely arsenic) due to the dissolution of specific minerals; and (ii) human contaminant activities, related to urban areas without sewage network, or with industrial activities, storage of hazardous products, and solid waste facilities. Among the anthropic compounds commonly handled, the most problematic are the chlorinated organic solvents and heavy metals, and in non-sewage areas, nitrate. The precarious knowledge of aquifer-quality, especially in cities, demonstrates the need to invest in regular and systematic hydrogeological research and mapping projects that drive to the improvement of the practices on aquifer quality protection.

title: Impact responses of slender composite plates for bird-strike testing of fan blades

description: Abstract Bird-strike failure of fan blades is one of the basic challenges for the safety of aircraft engines. Simplified slender blade-like plates are always used to evaluate the impact-induced damage mechanism at design stage. One undesirable issue is the failure at the root of clamped slender plates, which cannot recover the real case of twisted blades. For this purpose, three different strategies were exploited to obtain desirable deformation and stress responses, namely the impact location, additional weight, and the boundary condition. Numerical models of the simplified slender blade and the bird projectile were constructed by using finite element method (FEM) and smoothed particle hydrodynamics (SPH) approaches. The impact deformations and stress distributions were comparatively investigated in detail. The numerical results show that changing the boundary condition is the most effective way to obtain preferable impact responses for further failure analysis of real fan blades. Present results will be useful to future experimental design of simplified bird-strike testing.

title: Who has it worse? Northeastern and Bolivian workers in the São Paulo job market

description: Abstract The article compares income differentials of Bolivian and Northeastern workers in the State of São Paulo based on data from the 2010 Demographic Census. The strategy of comparing internal and international migrants is a way of trying to understand how mechanisms of selectivity, adaptation and discrimination by origin operate. Statistical models were used to control the analyses and to know if Bolivians and Northeastern people with characteristics as similar as possible in terms of census variables, would present a salary differential, leaving the place of birth as the only discriminant variable. From the decomposition of wage differentials, we verify that the productive attributes of these immigrants are valued differently. The analysis shows that Bolivians "do better" when compared to Northeasterners, who find themselves in a worse situation, given the lower valuation of their individual attributes.

title: Characterization of amputees at a large hospital in Recife, PE, Brazil

description: Abstract Background Limb amputation can be defined as a procedure that consists of separating a limb or a segment of a limb from the body. Objectives To describe the profile of limb amputation procedures performed at a large hospital run by the state of Pernambuco (Brazil). Methods Cross-sectional descriptive and retrospective study conducted at a large hospital in the city of Recife, PE. Data were collected from the records of patients who underwent amputations during 2017. Records from patients who had had a limb amputation during 2017 were included, unless data were illegible or missing. Results A total of 328 procedures were performed on 274 patients, the majority of whom were male (57.7%). There was a predominance of lower limb amputations (64.2%), of non-traumatic causes (86.5%), and urgent treatment (96.4%). The majority of patients who underwent amputations remained in hospital for 11 to 25 days (32.1%). The study found that the majority of amputees were discharged (69.7%), although a proportion died. Deaths of lower limb amputees were primarily among elderly women in the age range of 60 to 90 years (76%), females (55%), and patients subjected to a single amputation (91%). Conclusions The data observed in this study are alarming, particularly considering that many of these amputations could have been avoided, since they were caused by complications of diseases that can be prevented and controlled at healthcare services of a lower level of complexity and at a relatively low cost.

title: Dry eye in systemic lupus erythematosus patients

description: Abstract Objective: To study the association of dry eye with lupus disease activity and cumulative damage. To verify if epidemiological, treatment and autoantibody profile of SLE (systemic Lupus erythematosus) patients influence the presence of dry eye. Methods: We studied 70 SLE patients for the presence of dry eye by Schirmer test, disease activity by SLEDAI (SLE-Disease activity index) and cumulative damage by SLICC/ACR DI (Systemic Lupus International Collaborating Clinics/American College of Rheumatology Damage Index). Patients were also submitted to the OSDI (Ocular Surface Disease Index) questionnaire. Epidemiological and treatment data and autoantibody profile were extracted from the charts. Results: Dry eye by Schirmer test was present in 51.4% of the sample. No association of the presence of dry eye with SLEDAI and SLICC DI were found (p = ns). Subjective symptoms of dry eye measured by OSDI showed a modest correlation with SLEDAI (Spearman rho = 0.32). Treatment profile did not influence in the presence of dry eye that was more common in older patients (p &lt; 0.0001). Anti dsDNA had a negative association with the presence of positive Schirmer test (p = 0.0008). Conclusions: Dry eye detected by Schirmer test in SLE patients has no association with disease activity nor cumulative damage. Anti dsDNA seems to have a protective effect in this context.
