title: Rates and methods of phosphorus application in cabbage crop

description: ABSTRACT The efficiency of phosphate fertilization may be reduced by incorporating the fertilizer to the soil using a rotary tiller, which is a method commonly adopted to grow vegetables. This study aimed to evaluate the yield of cabbage crop and the efficiency of phosphate fertilization based on rates and application methods of P to the soil. Four experiments were carried out [two using broadcasting application (0 kg ha-1, 200 kg ha-1, 400 kg ha-1, 800 kg ha-1 and 1,600 kg ha-1 of P2O5) and two using localized application (0 kg ha-1, 80 kg ha-1, 160 kg ha-1, 320 kg ha-1 and 640 kg ha-1 of P2O5, combined with the presence or absence of phosphating - application of 200 kg ha-1 of P2O5 by broadcasting)] in two growing sites [one with low (A) and another with high (B) content of P, both showing a very clayey texture]. The rates of 252 kg ha-1 and 284 kg ha-1 of P2O5 were estimated to obtain the maximum economic productivity in the broadcasting application at the sites A and B, respectively. The best rates were 183 kg ha-1 and 146 kg ha-1 of P2O5 with the localized application of P without phosphating at the sites A and B, respectively. To obain 95 % of maximum yield, the recovery efficiency was 48.9 % and 30.0 % at the sites A and B, respectively. For the localized application of P in the absence of phosphating, these values were 44.6 % and 60.4 % at the sites A and B, respectively. With phosphating, the recovery efficiency decreased significantly. The localized application of P is more efficient than the broadcasting application to supply nutrients and increase the cabbage yield.

title: Physiological quality of Urochloa brizantha seeds submitted to priming with calcium salts

description: ABSTRACT Seed priming provides a variety of benefits, including seed invigoration and reduced dormancy. Urochloa brizantha seeds are typically primed with difficult-to-acquire potassium nitrate (KNO3). In this sense, calcium salts stand out as an alternative, but it is important to determine whether they provide the same benefits as potassium nitrate. This study aimed to evaluate the physiological quality of U. brizantha seeds after priming with calcium salts, and compare the results to those obtained with potassium nitrate. Seeds were submitted to priming with calcium nitrate [Ca(NO3)2] and calcium sulphate (CaSO4) at -0.55 MPa and -1.10 MPa, for 12 h and 24 h, and potassium nitrate (KNO3) at -1.10 MPa for 12 h, as well as to no priming (control). A completely randomized design, with ten treatments and four repetitions, was used. Priming promoted a higher germination percentage and lower seed dormancy, with a greater seedling emergence in a shorter time period. CaSO4 did not differ from KNO3 in shoot dry weight of seedlings, but reduced the electrical conductivity of seeds. Calcium nitrate and calcium sulfate show a promising potential for use in the osmotic priming of Urochloa brizantha (BRS Piatã cultivar) seeds, since they are as efficient as potassium nitrate, as well as less costly and easier to purchase. Calcium sulfate priming at -0.55 MPa for 12 h, at 25 ºC, is recommended to replace the potassium nitrate solution.

title: Biochar and mucuna increase papaya plant growth and nutrition, as well as soil fertility

description: ABSTRACT The association between biochar and green manure in the papaya crop may be a promising management technique, mainly in its first growth stage. This study aimed to evaluate the effects of biochar and green manure (Mucuna aterrina) on the growth and nutrition of Carica papaya seedlings, as well as on soil fertility. The experiment followed a randomized block design (5 blocks), in a 2 x 2 factorial arrangement: with and without mucuna and with and without biochar. The biochar or mucuna application significantly increased the papaya plant shoot and root growth, as well as the chemical features of the soil, whereas their joint application did not provide synergistic effects, except for the leaf P concentration. The application of biochar and biochar + mucuna enabled a fast initial increase in plant height. However, it also showed a visible N deficiency, despite the increased N, P, K, Ca and Mg accumulation and use efficiency in the plants. The effect of the biochar/mucuna joint application is synergistic for the leaf P content and plant height. The individual or joint application of biochar and mucuna increases the papaya plant growth and nutrition and maintains the soil fertility.

title: Evaluation of platelet concentrate prescription in pediatric patients at a tertiary care hospital

description: ABSTRACT Objective: To verify the adequacy of platelet concentrate prescription by pediatricians in different pediatric sectors of a general hospital. Methods: A cross-sectional study evaluating 218/227 platelet concentrate records in children and adolescents (zero to 13 years old), from January 2007 to April 2015, by the pediatricians of the emergency room, sick bay and intensive care unit. The requisitions were excluded in patients with hematological diseases and those without the number of platelets. Results: Children under 12 months received 98 platelet concentrates (45.2%). Most of the transfusions were prophylactic (165; 79%). Regarding the transfusion site, 39 (18%) were in the emergency room, 27 (12.4%) in the sick bay and 151 (69.6%) in the intensive care unit. The trigger, prescribed volume and platelet concentrate subtype were adequate in 59 (28.2%), 116 (53.5%) and 209 (96.3%) of the transfusions, respectively. Patients with hemorrhage presented adequacy in 42 (95.5%), while children without bleeding presented in 17 (10.3%). The most common inadequacy related to volume was the prescription above recommendation (95; 43.8%). Eight platelet concentrates were prescribed with subtype requests without indication. Conclusion: The results obtained in this study showed that transfusion of platelet concentrate occurred more adequately in children with active bleeding compared to prophylactic transfusion. There was a tendency to prescribe high volumes and platelet subtypes not justified according to current protocols. The teaching of transfusion medicine should be more valued at undergraduate and medical residency.

title: The gender role in the relationship between food-related perceived resources and quality of life among ecuadorian elderly

description: Abstract Individuals not only have a set of personal resources to carry out their activities, they also have a perception with respect to the availability of these resources. As people age, personal food-related perceived resources (FPR) become increasingly important, and these influence their quality of life (QOL). Since men and women differ in aspects like education, consumption and pensions, this study seeks to identify the gender role in the relationship between FPR and QOL among Ecuadorian elderly. The sample included elderly people of both sexes in the city of Guayaquil, Ecuador, with the application of stratified random sampling. The instrument included: FPR scale, satisfaction with food-related life scale (SWFLS) and the satisfaction with life scale (SWLS). The results indicated that those men and women who have a better perceived satisfaction with their economic situation are in physically and mentally good health, assign greater importance to family, are more satisfied with their food-related life, and have a higher number of FPR and therefore a better QOL. A relevant conclusion is that SWFLS and FPR are predictors of QOL among Ecuadorian elderly and that gender helps to explain the sign and magnitude of the relationship between these variables.

title: Prevalence of Systemic Arterial Hypertension and Associated Factors Among Adults from the Semi-Arid Region of Pernambuco, Brazil

description: Abstract Background: Systemic arterial hypertension is a substantial public health problem responsible for millions of deaths per year worldwide. However, little is known about the epidemiology of this disease in areas distant from large urban centers in Brazil. Such information is necessary to plan health promotion strategies. Objective: To estimate the prevalence of hypertension and determine its associated factors in adults residing in the semi-arid region of the state of Pernambuco, Northeastern Brazil. Method: This is a cross-sectional study conducted with a random sample of male and female adults. Individuals with systolic blood pressure ≥ 140 mm/Hg and/or diastolic blood pressure ≥ 90 mm/Hg and those who reported being under treatment with antihypertensive drugs were considered hypertensive. We collected data on demographic, socioeconomic, behavioral, and anthropometric characteristics, as well as health and nutrition. The statistical analysis used Pearson’s chi-square test, the chi-square test for trend, and multivariate Poisson regression analysis. A p-value &lt; 0.05 in the final model was considered indicative of statistical significance. Results: The sample consisted of 416 individuals, and the prevalence of hypertension was 27.4% (95%CI 23.2 - 32.0). In the final model, the independent predictors of hypertension were age of 40 years or older (p = 0.000), low economic class (p = 0.007), smoking (p = 0.023), overweight determined by the body mass index (p = 0.003), and reduced glucose tolerance/diabetes mellitus (p = 0.012). Conclusion: The prevalence of hypertension was high and related to important risk factors. Thus, prevention and control strategies are recommended.

title: Physiological potential and initial development of soybean plants as a function of seed treatment

description: ABSTRACT Seed treatment is a process that helps to control insects and soil-borne pathogens, besides allowing a given crop to reach its maximum production potential and protect its seedlings. This study aimed to evaluate the physiological performance of seeds and the initial development of soybean, as a function of seed treatment. The study was based on a completely randomized design, with five treatments [imidacloprid + thiodicarb (75 + 225 g a.i. 100 kg-1 of seeds); chlorantraniliprole (62.5 g a.i. 100 kg-1 of seeds); cyantraniliprole (72 g a.i. 100 kg-1 of seeds), fipronil + thiophanate-methyl + pyraclostrobin (5 + 45 + 50 g a.i. 100 kg-1 of seeds); and control (seeds without treatment)]. Initially, the physiological quality of the seeds was evaluated by determining the first germination count, final germination and accelerated aging, with four replications. After that, the effect of the seed treatment on the soybean plant development was evaluated by analyzing the leaf area, number of leaves, shoot height, root and shoot dry mass and fresh mass of root nodules, with ten replications. The seed treatment with fipronil + pyraclostrobin + thiophanate-methyl allows an increased germination when the seeds are subjected to the accelerated aging test, besides an increment in the shoot height and leaf area of the plants.

title: Ocular surface evaluation in pediatric Hashimoto's thyroiditis without thyroid-associated ophthalmopathy

description: ABSTRACT Purpose: We aimed to assess ocular surface characteristics in children with Hashimoto's thyroiditis without thyroid-associated ophthalmopathy and compare the results with those of healthy children. Methods: Twenty-two children with Hashimoto's thyroiditis (Group 1) and 20 healthy children without any ocular and/or systemic disorder (Group 2) were enrolled in the study. Ocular Surface Disease Index questionnaire, tear film osmolarity measurement (TearLab Osmolarity System, San Diego, CA, USA), Schirmer and tear film breakup time tests, meibography, and conjunctival brush cytology were performed and compared the results between the groups. Results: The study group included 19 girls and 3 boys in Group 1 and 12 girls and 8 boys in Group 2 (p=0.081). Thyroid-associated ophthalmopathy was not identified in any of the patients. Mean tear film osmolarity was 310.23 ± 11.98 mOsm/l in Group 1 and 313.60 ± 15.03 mOsm/l in Group 2 (p=0.424). Mean Schirmer test score was lower in Group 1 (14.91 ± 6.27) compared with Group 2 (23.60 ± 5.63) (p=0.001). Mean tear film breakup time was lower in Group 1 (11.78 ± 4.07) compared with Group 2 (15.1 ± 1.6) (p=0.013). Moreover, mean meibomian gland area loss was 25.01% ± 10.04% in Group 1 and 16.54% ± 6.02% in Group 2 (p=0.002). Conjunctival cytologic analysis in Group 1 revealed grade 0 changes in 6 patients (27.3%), grade 1 changes in 14 patients (63.6%), and grade 2 changes in 2 patients (9.1%), whereas 18 patients (90%) had grade 0 changes and 2 patients (10%) had grade 1 changes (p=0.001) in Group 2. Conclusions: The study demonstrates several ocular surface changes in children with Hashimoto's thyroiditis. These findings may indicate a tendency for dry eye in pediatric Hashimoto's thyroiditis patients without clinical evidence of thyroid-associated ophthalmopathy.

title: Decision making from the perspective of nursing students

description: ABSTRACT Objective: To analyze the decision making of students from a nursing higher school and understand how they make decisions in the care process. Method: A qualitative study with an exploratory and descriptive approach was carried out with the case study method. Results: Six types of decision making were categorized by the students as follows: Decision about communication (15 record units [RU]); Decision about understanding (14 RU); Decision about intervention (9 RU); Decision about timing (5 RU); Decision about targeting (4 RU); and Decision about management (0 RU), with a total of 47 RU. Final considerations: Analysis of the learning diaries showed that students make more decisions regarding communication with patients and understanding of the care situation, than with the acting decision.

title: Decentralising scientific publishing: can the blockchain improve science communication?

description: We present a decentralised solution for managing scientific communication, based on distributed ledger technologies, also called blockchains. The proposed system aims to solve incentive problems displayed by traditional systems in scientific communication and publication. A minimal working model is presented, defining roles, processes, and expected results from the novel system. The proposed solution is viable, given the current status of blockchain technology, and should lead to a rethinking of current practices and their consequences for scientific communication.
