title: Rheological behavior of concentrated tucupi

description: Abstract Tucupi, which is widely enjoyed in the North region of Brazil, is a fermented liquid derived from cassava (Manihot esculenta Crantz) and has been taken abroad for its exotic characteristics. This study aimed to assess the rheological behavior of tucupi with 30, 35, and 40% solids and concentrated at 50, 70, and 90 °C. The rheological data were obtained at 25, 40, 60, and 80 °C with increasing and decreasing shear rates. Rheology at 25 °C indicated that the partial gelification of starch during concentration causes a decrease in the product’s viscosity and, if the concentration is carried out at a temperature that favors total starch gelification, the product’s viscosity increases. Concentrated tucupi behaved as a pseudoplastic fluid, but at 60 and 80 °C with increasing shear rates, the product behaved as a dilatant fluid. Hysteresis were observed in flow curves starting at 40 °C, which characterizes concentrated tucupi as a rheopectic fluid. The Ostwald-de Waele model predicted the product’s flow curves and an Arrhenius-like equation described the dependence of temperature on apparent viscosity for the rheological data obtained with increasing shear rates. The product’s activation energy (E a) values ranged from 16.86 to 25.23 kJ/mol as a function of concentration.

title: Peach palm flour (Bactris gasipae KUNTH): potential application in the food industry

description: Abstract Peach palm flours prepared from the landraces microcarpa (MIF), mesocarpa (MEF), and macrocarpa (MAF) were assessed for their functional and morphological characteristics. The flours had moisture contents in accordance with the current legislation, considerable lipid (≥3.95%) and carbohydrate (≥66.68%) contents, and potential as an energy source (≥300 kcal/100 g). MEF and MAF can be considered rich in dietary fibers since their fiber contents were above 6 g/100 g, which contributes to the nutritional enrichment of products prepared with those flours. The assessment of the technological properties, WAC (≥255%) and OAC (≥65%) showed the peach palm flours can be used as raw material in different products such as breads, cakes, meat products, and breaded foods, thus adding energy, nutritional, and economic value. It is worth pointing out that peach palm is gluten free, hence it is an option for the development of new products targeted at consumers with celiac disease.

title: Use of client-centered virtual reality in rehabilitation after stroke: a feasibility study

description: ABSTRACT Patient-centered virtual reality (VR) programs could assist in the functional recovery of people after a stroke. Objectives: To analyze the feasibility of a rehabilitation protocol using client-centered VR and to evaluate changes in occupational performance and social participation. Methods: This was a mixed methods study. Ten subacute and chronic stroke patients participated in the rehabilitation program using games in non-immersive VR for 40 minutes/day, three days/week, for 12 weeks. Sociodemographic information was collected and the outcome variables included were the Canadian Occupational Performance Measure (COPM) and the Participation Scale. A field diary was used to record the frequency of attendance and adherence of participants and an interview was conducted at the end of program. Results: There were significant and clinically-relevant statistical improvements in the COPM performance score (p &lt; 0.001; CI = 1.29 − 4.858) and in the COPM satisfaction score (p &lt; 0.001; CI = 1.37 − 5.124), with a difference greater than 4.28 points for performance and 4.58 points for satisfaction. The change in the scores for participation was statistically significant (p = 0.046), but there was no clinical improvement (dcohen = −0.596, CI = −1.862 − 0.671). The majority of participants reported more than 75% consecutive attendance of sessions and there was 100% adherence to the program. In the interviews, the participants described their post-stroke difficulties; how the video game motivated their engagement in rehabilitation; and the improvement of occupational performance and social participation after participating in the program. Conclusions: VR is a viable tool for the rehabilitation of stroke patients with functional gains, mainly regarding occupational performance and performance satisfaction.

title: The electric boat charging problem

description: Abstract Paper aims This paper studies a new optimization problem called the Electric Boat Charging Problem (EBCP), which is based on the application of electric mobility in a river transport operation problem. Originality This work pioneers the studies of the electric mobility on the river operations, by proposing the EBCP. This problem includes real features of the electric mobility such as nonlinear charging functions, battery degradation costs, and speed variation. Research method For solving the EBCP, we propose a Mixed-Integer Linear Programming (MILP) formulation. For testing our MILP formulation, we use a set of instances based on a future transport operation. We also analyze the impact of some problem parameters on the objective function, and decision variables. Main findings Our MILP formulation is capable to optimally solve different type of instances in competitive CPU times. The battery capacity and a time limit constraint have and important impact on the objective function and the decision-making variables. Implications for theory and practice We model the EBCP as a MILP formulation. This model allows to optimally solve industrial scale instances. Moreover, using a sensitivity analysis, we unveil that both the battery capacity and the time limit constraint of the EB route are critical parameters.

title: Transvaginal ultrasound in deep endometriosis: pictorial essay

description: Abstract Endometriosis is characterized by the presence of endometrial tissue outside the uterus. When endometrial implants penetrate more than 5 mm into the peritoneum, the condition is referred to as deep pelvic endometriosis. Although laparoscopy is the gold standard test to establish a diagnosis of deep endometriosis, transvaginal ultrasound represents an alternative that can contribute to detection of the disease, because it is an accessible, low-cost, noninvasive examination that allows preoperative planning in cases requiring surgical treatment. However, in clinical practice, transvaginal ultrasound is still not widely used as the first-line examination in suspected cases of endometriosis. This essay describes the findings of deep endometriosis on transvaginal ultrasound, in order to disseminate knowledge of the utility of the technique for the diagnosis of this disease.

title: Simultaneity of behavioral risk factors for chronic non-communicable disease among low-income undergraduate students from a city in southern Brazil

description: Abstract Background Few studies have investigated the prevalence and correlates of risk factors for non-communicable diseases (NCDs) among low-income undergraduate students in Brazil. Objective To investigate the co-occurrence of the main behavioral risk factors for NCDs (physical inactivity, low fruit and vegetables intake, binge drinking and smoking) in this population. Method Cross-sectional study was carried out during 2013, with 766 undergraduate students living in student housing at the Universidade Federal de Santa Maria, RS, Brazil. The simultaneous prevalence of risk factors was evaluated by a score created from the sum of individual behaviors. Poisson regression was applied for evaluating the associated factors with ≥3 risk factors, simultaneously. Results It was observed that 1.8% of students show no risk factor, while 19.5%, 49.3%, 24.9% and 4.5% presented one, two, three and four risk factors, respectively. Male (PR=1.35; 95%CI: 1.08-1.69), overweight/obesity (PR=1.37; 95%CI: 1.08-1.73) and morbidity history (PR=2.09; 95%CI: 1.52-2.87), only in males, were associated with the co-occurrence of risk factors. The combination involving all four risk factors showed a higher prevalence than the expected (O/E=1.76: 95%CI: 1.24-2.50). Conclusion The simultaneous prevalence of risk factors in low-income college students was high, this finding that may help in the formulation of prevention programs and interventions.

title: QT Dispersion Changes after Transcatheter Aortic Valve Implantation in Patients with Aortic Stenosis

description: Abstract Objective: The aim of this study was to evaluate the QT dispersion and echocardiographic parameters in patients before and after transcatheter aortic valve implantation (TAVI). Methods: One hundred and fifty-two patients with severe aortic valve stenosis (AS) were included in our study. Ninety five patients who underwent aortic valve replacement with TAVI were included in the TAVI group and 57 patients, who refused TAVI, were included in the medical treatment group. The QT interval and echocardiographic parameters of all patients were assessed before and after the procedure (first and sixth months and first year). The QT intervals were taken from the onset of the QRS to the end of the T wave. Results: All patients had severe AS. The average mean aortic valve gradient was 46.1±12. Left ventricular internal diastolic diameter (LVIDD) and interventricular septum diastolic thickness (IVSDT) did not change signiﬁcantly after TAVI (P&gt;0.05). QT dispersion, corrected QT dispersion, and mean aortic valve gradient changed signiﬁcantly six months after TAVI (P&lt;0.05). Compared to the medical treatment group, QT dispersion and corrected QT dispersion were significantly decreased at the sixth month in the TAVI group. The incidence of malignant arrhythmias was smaller in the TAVI group than in the medical treatment group. The mortality rate was lower at the first-year follow-up in the TAVI group than in the medical treatment group. Conclusion: Increased QT dispersion is associated with severe symptomatic AS. After TAVI, QT dispersion reduces.

title: Genetic variability in conilon coffee related to grain attributes in an irrigated crop in the Cerrado

description: Abstract: The objective of this work was to quantify the genetic variability of 213 conilon coffee accessions of the Robusta Tropical cultivar, based on chemical characteristics related to the quality of green coffee beans, as well as to identify promising accessions for the breeding program of irrigated conilon coffee in the Brazilian Cerrado. The chemical characteristics evaluated were: protein and caffeine contents, total soluble solids and total lipids, ether extract, pH, and total titratable acidity. The data were subjected to the principal component analysis and cluster analysis based on the similarities observed within the first two principal components using the minimum variance method (Wards) and, as a measure of similarity, the Euclidean distance. The three main components explained 72.64% of the total variation of the data. All characteristics, except pH, were correlated with the first three components. It was possible to separate the genotypes in three clusters, according to the similarities observed in the behavior of the variables. The evaluated accessions present genetic variability regarding the assessed quality characteristics of green coffee beans, and CPAC 160 and CPAC 32 are the most promising for the breeding program of conilon coffee for cultivation under irrigation in the Cerrado.

title: Soil patterns and foliar standards for two cocoa clones in the States of Espírito Santo and Bahia, Brazil

description: ABSTRACT: The objective of this research was to establish soil patterns and foliar standards for clonal crops of cocoa CCN51 and PS1319 in the Atlantic regions within the northern Espírito Santo and southern Bahia States. Samples were collected from September to October 2015, in 45 high productive plots, being 23 plots of clone CCN51 and 22 of clone PS1319. Sufficiency ranges for soil and foliar standards were recommended for cocoa clones CCN51 and PS1319 planted in the Northern Espírito Santo and Southern Bahia states. Differences in the contents of foliar macronutrients K, Ca, Mg, S and micronutrients Fe and Mn, were verified between clones CCN51 and PS1319. Differences reported for standards from different geographical regions confirmed that these standards need to be regional and specific for different cocoa clones.

title: Risk of Obstructive Sleep Apnea and Echocardiographic Parameters

description: Abstract Background: Obstructive sleep apnea (OSA) is a chronic progressive disorder with high mortality and morbidity rate, associated with cardiovascular diseases (CVD), especially heart failure (HF). The pathophysiological changes related to OSA can directly affect the diastolic function of the left ventricle. Objectives: To assess the association of the risk of OSA, evaluated by the Berlin Questionnaire (BQ), and echocardiographic (ECHO) parameters related to diastolic dysfunction in individuals without HF assisted in primary care. Methods: A cross-sectional study that included 354 individuals (51% women) aged 45 years or older. All individuals selected were submitted to an evaluation that included the following procedures: consultation, filling out the BQ, clinical examination, laboratory examination and transthoracic Doppler echocardiography (TDE). Continuous data are presented as medians and interquartile intervals, and categoric variables in absolute and relative frequencies. The variables associated with risk of OSA and at the 0.05 level integrated the gamma regression models with a log link function. A value of p &lt; 0.05 was considered an indicator of statistical significance. Exclusion criteria were presence of HF, to fill out the BQ and patients with hypertension and obesity not classified as high risk for OSA by other criteria. All individuals were evaluated on a single day with the following procedures: medical appointment, BQ, laboratory tests and ECHO. Results: Of the 354 individuals assessed, 63% were classified as having high risk for OSA. The patients with high risk for OSA present significantly abnormal diastolic function parameters. High risk for OSA confirmed positive and statistically significant association, after adjustments, with indicators of diastolic function, such as indexed left atrium volume LAV-i (p = 0.02); E’/A’ (p &lt; 0.01), A (p = 0.02), E/A (p &lt; 0.01). Conclusion: Our data show that patients at high risk for OSA present worsened diastolic function parameters measured by TDE.

title: Potential of figs from cultivars grown in subtropical regions for canning purposes

description: Abstract: The objective of this work was to evaluate the influence of fig (Ficus carica) cultivars grown in subtropical regions on the physicochemical, rheological, and sensorial characteristics of the canned figs. Fresh fruits of the cultivars were analyzed for length, diameter, unit mass, total soluble solids, total titratable acidity, pH, total soluble solids/total titratable acidity ratio, and color. Canned figs were evaluated for titratable acidity, pH, color, texture profile, and sensory characteristics. The different physicochemical characteristics of the fresh figs influenced those of the obtained canned fruits. The canned figs from 'Lemon' and 'Pingo de Mel' presented the lowest and highest pH, respectively, whereas those from 'Troiano' showed the highest total titratable acidity. As for color, after processing, the canned figs, in general, presented a more greenish and darker color than the fresh fruits. The canned figs from 'Brunswick' and 'Troiano' had the lowest acceptance, whereas those from 'Bêbera Branca' and 'Roxo de Valinhos', the greatest. Less acid and softer canned figs are more widely accepted, which can be obtained from all cultivars, except from Brunswick and Troiano.
