title: Spatial analysis of the tuberculosis treatment dropout, Buenos Aires, Argentina

description: OBJECTIVE Identify spatial distribution patterns of the proportion of nonadherence to tuberculosis treatment and its associated factors.METHODS We conducted an ecological study based on secondary and primary data from municipalities of the metropolitan area of Buenos Aires, Argentina. An exploratory analysis of the characteristics of the area and the distributions of the cases included in the sample (proportion of nonadherence) was also carried out along with a multifactor analysis by linear regression. The variables related to the characteristics of the population, residences and families were analyzed.RESULTS Areas with higher proportion of the population without social security benefits (p = 0.007) and of households with unsatisfied basic needs had a higher risk of nonadherence (p = 0.032). In addition, the proportion of nonadherence was higher in areas with the highest proportion of households with no public transportation within 300 meters (p = 0.070).CONCLUSIONS We found a risk area for the nonadherence to treatment characterized by a population living in poverty, with precarious jobs and difficult access to public transportation.

title: Association between social capital and self-perception of health in Brazilian adults

description: OBJECTIVE To investigate the association between social capital and social capital and self-perception of health based on examining the influence of health-related behaviors as possible mediators of this relationship.METHODS A cross-sectional study was used with 1,081 subjects, which is representative of the population of individuals aged 40 years or more in a medium-sized city in Southern Brazil. The subjects who perceived their health as fine, bad or very bad were considered to have a negative self-perception of their health. The social capital indicators were: number of friends, people from whom they could borrow money from when needed; the extent of trust in community members; whether or not members of the community helped each other; community safety; and extent of participation in community activities. The behaviors were: physical activity during leisure time, fruits and vegetable consumption, tobacco use and alcohol abuse. The odds ratios (OR) and confidence intervals (CI) 95% were calculated by binary logistic regression. The significance of mediation was verified using the Sobel test.RESULTS Following adjustment for demographic and clinical variables, subjects with fewer friends (OR = 1.39, 95%CI 1.08;1.80), those who perceived less frequently help from people in the neighborhood (OR = 1.30, 95%CI 1.01;1.68), who saw the violent neighborhood (OR = 1.33, 95%CI 1.01;1.74) and who had not participated in any community activity (OR = 1.39, 95%CI 1.07;1.80) had more negative self-perception of their health. Physical activity during leisure time was a significant mediator in the relationship between all social capital indicators (except for the borrowed money variable) and self-perceived health. Fruit and vegetable consumption was a significant mediator of the relationship between the extent of participation in community activities and self-perceived health. Tobacco use and alcohol abuse did not seem to have a mediating role in any relationship.CONCLUSIONS Lifestyle seems to only partially explain the relationship between social capital and self-perceived health. Among the investigated behaviors, physical activity during leisure time is what seems to have the most important role as a mediator of this relationship.

title: Chemical composition, antioxidant activity and development of desserts with azuki beans (Vigna angularis)

description: Abstract In Japan, azuki beans are commonly used in the preparation of desserts and their red seed coats are rich in antioxidants. In Brazil, azuki beans are still little consumed and the bean dessert little known by Brazilians. The aim of this study was to characterize red azuki beans (Vigna angularis) by means of chemical analyses, evaluate the influence of cooking on the total phenolic compound contents and antioxidant activity, and also evaluate the chemical composition of desserts formulated with azuki beans. The results obtained for the chemical composition showed that azuki beans presented high carbohydrate (65.60 g/100 g) and protein (17.87 g/100 g) contents. When compared to raw azuki beans, the cooked beans had lost most of the phenolic compounds, but still maintained nearly half of the antioxidant activity. The azuki bean desserts in the solid and paste forms presented, respectively, high carbohydrate contents (67.09 and 46.20 g/100 g), good protein contents (4.02 and 6.48 g/100 g) and low lipid contents (0.33 and 2.73 g/100 g). The red azuki beans showed good technological potential for use in the processing of bean desserts.

title: Strawberries produced in the semi-arid region of Minas Gerais, Brazil: quality of the frozen fruit and pulp

description: Abstract The freezing of whole strawberries or pulp can provide raw material for the out of season use of strawberries in yogurts, fillings, toppings, ice cream and juices. However, although the consumption is not in natura, the quality of the final product should be satisfactory. This study aimed to evaluate the quality of strawberries produced in the semi-arid region of Minas Gerais, Brazil, frozen either whole or in the form of pulp, during storage. Fruits of the cultivars Tudla, Oso Grande, Albion and Portola were produced in the semi-arid region of Minas Gerais, and after harvesting, were washed, vacuum packed (whole or pulp) and frozen for up to 180 days. The treatments consisted of cultivars (c) and days of storage (d), constituting a double factorial c × d design, using three repetitions of 10 fruits per batch or three pulp-packs, respectively, for the frozen whole fruit assessments. The intensity of the red colour of the whole strawberries or strawberry pulp reduced during storage (reduction of hue). When whole, the cultivars 'Tudla', 'Oso Grande' and 'Portola’ were a lighter red than' Albion ', but in the form of pulp, there was no difference between 'Tudla' and 'Albion'. The 'Oso Grande' strawberries, stored whole or in pulp, showed higher soluble solids contents than those of the other cultivars, and 'Portola' showed the lowest content and also the lowest titratable acidity (when whole). The fruits and pulp of the ‘Tudla’ cultivar were more acidic. During the storage of frozen whole or pulped strawberries produced in the semi-arid region of Minas Gerais, changes occurred in the colour, soluble solids and titratable acidity.

title: Extraction of oleuropein from olive leaves using a hydroalcoholic solvent

description: Abstract Olive leaves contain oleuropein, a substance known for its antioxidant, antimicrobial and antiinflammatory potentials, amongst others. The objective of this work was to study the extraction of oleuropein using a hydroalcoholic solvent. Olive leaves (OL) were macerated at 25 °C with a solvent (S) consisting of a mixture of ethanol and water (70:30 v/v), with OL:S mass ratios equal to 1:8, 1:6 and 1:3, with or without the presence of acetic acid. The highest oleuropein content found in the freeze dried extract (approximately 18 g/100 g) was obtained from the procedure using an OL:S ratio = 1: 3, in the presence of acetic acid. Finally, a test was carried out to verify the effect of the freeze dried extract on the induction time in samples of extra-virgin and refined olive oil, and increases of 3 and 2 hours, respectively, were observed. It was concluded that it is possible to obtain olive leaf extracts using renewable solvents, and that oleuropein can act as a natural antioxidant in olive oil, improving its oxidative stability.

title: Foam-mat drying kinetics for acerola and adjustment of the mathematical models

description: Abstract Acerola (Malpighia emarginata DC) is a fruit rich in nutrients, especially vitamin C, but the in natura fruit is highly perishable and hence processing of the acerola pulp becomes indispensable. The aim of this paper was to study the foam mat drying process of acerola pulp to evaluate the effect of temperature on the drying kinetics of the pulp and fit mathematical models in order to describe the operation. The experiment was carried out with three repetitions. The foam was prepared with 250 mL of the pulp plus 4% of foaming agent and spread evenly in stainless steel trays. The selected drying air temperatures were 50 °C, 55 °C, 60 °C, 65 °C and 70 °C. The moisture ratios were then calculated and the Page, Henderson and Pabis and Lewis mathematical models fitted for each temperature. The Page model showed the highest determination coefficient (&gt; 0.99) and lowest standard error for the regression at all temperatures (&lt;0.03). The proposed generalized model presented a determination coefficient of 0.9933. The Page model and the generalized model were adequate to describe the drying process of the acerola pulp. The moisture contents of the dehydrated products were in accordance with the values established by Brazilian law.

title: The new refugee crisis in Europe: the repulsion-attraction model revisited and the challenges for migration policies

description: Abstract &gt;This paper addresses the challenges resulting from the new refugee flows directed to Europe since the beginning of the second decade of the 21st century. Aiming to explain the new refugee crisis, the push-pull model is revisited and the role of agency – individual motives that induce migration – is confronted with interference from the structure – economic, social and political factors that explain the increase of flows, also attending to the dynamics and operation of the legal framework in the European context. Despite the scarce empirical evidence, we conclude that the new refugee movements pose profound challenges to observational and theoretical analyses, as well as to the existing legal framework. Further studies and new regulatory instruments are needed in order to respond to the size and complexity of such flows.

title: Transverse Sternal Split: a Safe Mini-invasive Approach for Perventricular Device Closure of Ventricular Septal Defect

description: Abstract Objective: Perventricular device closure of ventricular septal defect through midline sternotomy avoids the cardiopulmonary bypass, however, lacks the cosmetic advantage. Perventricular device closure of ventricular septal defect with transverse split sternotomy was performed to add the cosmetic advantage of mini-invasive technique. Methods: Thirty-six pediatric patients with mean age 7.14±3.24 months and weight 5.00±0.88 kg were operated for perventricular device closure of ventricular septal defect through transverse split sternotomy in 4th intercostal space under transesophageal echocardiography guidance. In case of failure or complication, surgical closure of ventricular septal defect was performed through the same incision with cervical cannulation of common carotid artery and internal jugular vein for commencement of cardiopulmonary bypass. All the patients were postoperatively followed, and then discharged from hospital due to their surgical outcome, morbidity and mortality. Results: Procedure was successful in 35 patients. Two patients developed transient heart block. Surgical closure of ventricular septal defect was required in one patient. Mean duration of ventilation was 11.83±3.63 hours. Mean intensive care unit and hospital stay were 1.88±0.74 days and 6.58±1.38 days, respectively. There was no in-hospital mortality. A patient died one day after hospital discharge due to arrhythmia. No patients developed wound related, vascular or neurological complication. In a mean follow-up period of 23.3±18.45 months, all 35 patients were doing well without residual defect with regression of pulmonary artery hypertension as seen on transthoracic echocardiography. Conclusion: Transverse split sternotomy incision is a safe and effective alternative to a median sternotomy for perventricular device closure of ventricular septal defect with combined advantage of better cosmetic outcomes and avoidance of cardiopulmonary bypass.
