title: Bone meal as a source of phosphorus for forage sugarcane1

description: ABSTRACT Phosphate fertilizers of organic origin may represent a viable alternative for the replacement of mineral fertilizers in the nutrition of crops such as forage sugarcane. This study aimed to investigate the effects of phosphate fertilization with bone meal and single superphosphate on the concentration of phosphorus (P) in the plant tissue, total soluble solids and yield aspects of forage sugarcane. A complete randomized block design was used, in a 2 × 5 factorial scheme, with four replicates. The treatments consisted of combining two phosphorus sources (single superphosphate and bone meal) and five P2O5 doses (0 kg ha-1, 50 kg ha-1, 100 kg ha-1, 150 kg ha-1 and 200 kg ha-1). Sugarcane plants fertilized with the addition of bone meal showed an increase in height and number of nodes (13 % and 15 %, respectively), when compared to the mineral fertilization with single superphosphate. The sugarcane attributes, in response to the P2O5 doses, were described by quadratic functions. The dose of 95.80 kg ha-1 of P2O5 in the bone meal led to the highest concentration of P in the plant tissue (3.60 g kg-1). The comparison between the sources of P at the doses of 100 kg ha-1 and 150 kg ha-1 of P2O5 showed that the total soluble solids content was 8.62 % and 13.84 % higher, respectively, in plants fertilized with bone meal.

title: Evaluation of leguminous species as cover crops associated with sacha inchi1

description: ABSTRACT Sacha inchi (Plukenetia volubilis) is an oilseed crop that has gained importance due to the high contents of proteins and unsaturated fatty acids in its seeds. This study aimed at evaluating the growth characteristics of five leguminous species (Crotalaria juncea,Centrosema macrocarpum,Arachis pintoi,Cannavalia ensiformis and Phaseolus vulgaris) used as cover crops, as well as determining their influence on the sacha inchi yield. A complete randomized block design, with three blocks, was used. C. macrocarpum and C. ensiformis were the most appropriate cover crop species for the local edaphoclimatic conditions because they reached 100 % of soil coverage at six months, in addition to controlling the weeds growth and protecting the soil from erosion. Furthermore, the total leaf biomass at six months was significantly higher in C. macrocarpum, what allowed improving the soil fertility through nitrogen cycling. The use of leguminous cover crops, mainly C. macrocarpum, positively influenced the sacha inchi yield.

title: Humic acids from vermicompost positively influence the nutrient uptake in mangosteen seedlings1

description: ABSTRACT The application of growth promoting substances, such as humic acids, during the formation of fruit seedlings can benefit growth and increase the plant nutrient uptake and translocation. This study aimed to evaluate the effect of the application of humic acid doses (0 mg L-1, 2 mg L-1, 20 mg L-1, 40 mg L-1 and 200 mg L-1) extracted from vermicompost of sugarcane filter cake on the nutrient uptake of seminal mangosteen (Garcinia mangostana L.) seedlings. The experimental design was completely randomized, with 7 replicates for each treatment. The application of humic acids promoted curvilinear increments with quadratic rates for N, P, K, Ca, Mg and S contents from shoots and roots, as well as quadratic increments in the Zn and Mn uptake by shoots. The application of humic acids increased the chlorophyll a and chlorophyll b contents and reduced the carotenoid content. Overall, the regression analysis demonstrated that a dose of 150 mg L-1 is capable of providing the most adequate nutrient uptake by plants, and should be recommended for the production of mangosteen seedlings. Humic acids from vermicompost can provide a better nutrition in mangosteen seedlings at the nursery stage.

title: EFFECTIVENESS OF PHOSPHORUS REMOVAL IN AN SBR USING CO-PRECIPITATION WITH FERRIC CHLORIDE, AND ITS EFFECTS ON MICROBIAL ACTIVITY

description: Abstract The present study evaluated the phosphorus removal in a Sequencing Batch Reactor (SBR - 2,500L) used to treat the wastewater from an office building in two steps: phase I-Enhanced biological phosphorus removal (EBPR) and phase II-co-precipitation using FeCl3 as precipitant. The raw sewage presented a high organic load variation ranging from 0.11 (phase I) to 0.66 (phase II) kgCOD.m-3.d-1. A better phosphorus removal performance was obtained during co-precipitation (from 19.0 to 1.2 mg.L-1 = 93% of efficiency) compared with biological removal (from 15.6 to 9.0 mgL-1 = 42% of efficiency). FISH analyses did not demonstrate a strong PAO inhibition; however, nitrifying and denitrifying organisms (NSO and PAE) showed a significant activity reduction during phase II. Therefore, the bench tests made to obtain the oxygen uptake rate (OUR) revealed a heterotrophic organisms activity significantly lower in phase II (46.8 mgDQOT.L-1) than phase I (211.8 mgDQOT.L-1), indicating metabolic inhibition. The co-precipitation processes enhanced phosphorus removal, bringing the SBR effluent into accord with state law requirements; however, the inhibitory effect of ferric chloride on microorganism activity was highlighted.

title: Adverse reactions to benznidazole in the treatment of Chagas’ Disease: a systematic review of randomized and controlled trials

description: Abstract Background In Brazil, the only drug available for the treatment of Trypanosoma cruzi, which causes Chagas' Disease (CD), is the Benznidazole (BZN) whose the adverse reactions might lead to treatment dropout. Objective The objective of this study is to quantify the proportion of occurrence of adverse effects, to describe them and to identify the risk factors associated with this occurrence. Method This is a systematic review conducted through the standards established by the Preferred Reporting Items in Systematic Reviews and Metanalyses (PRISMA). Only randomized controlled trials were included. Results Five of 134 studies were included. The sample size ranged from 77 to 2854 people, and the age range of the participants ranged from zero to 75 years old. All included studies reported adverse reactions to BZN use. The frequency of adverse reaction was 38% and the most common reaction was the skin rash. The treatment dropout caused by the adverse reactions was cited in three studies and was ranging from 6.4% to 13.4%. Conclusion The adverse reactions caused by the use of BZN varied with the age of patients and the therapeutic scheme of dose and time adopted. Therefore, medical knowledge is imperative for the safe use of BZN and adherence to treatment.

title: A 19-years study of the dental procedures performed in the Brazilian Unified Health System

description: Abstract Background Public health in Brazil has undergone major changes in recent decades. Objective To describe the overview of dental production performed by the Brazilian Unified Health System from 1999 to 2017 in Brazil and its macroregions. Method Data were obtained from the Outpatient Information System (SIA/SUS) and from the Brazilian Institute of Geography and Statistics (IBGE). Procedures rates (per 100,000 inhabitants per year) were established in each macroregion: restorative, prosthetic, collective, endodontic, exodontia, periodontic and preventive procedures. Statistical analysis of the time series was performed using a regression linear model. Results Prosthetic and periodontal procedures were the only ones with a positive linear trend in all Brazilian macroregions (p&lt;0.001). Endodontics did not show a positive trend in Brazil (p=0.173). Restorations showed a growth in the North (p=0.003) and Center-west (p&lt;0.001) macroregions. Exodontia presented a tendency to increase in the North macroregion (p=0.046), while the Midwest presented a decrease of it (p=0.049). Preventive (p=0.042) and collective (p=0.017) procedures showed a decrease in their production during the period. Conclusion Oral health showed great growth within the single health system in the 19 years evaluated. Periodontal procedures and dental prostheses were those with the highest growth trends.

title: Vulvar Tuberculosis-A Rare Manifestation of the Disease

description: Abstract Tuberculosis is an infectious disease caused by Mycobacterium tuberculosis. According to data from the World Health Organization, this disease remains one of the leading causes of death worldwide. Although it most commonly affects the lungs, tuberculosis can compromise any organ. The present study reports a rare case of vulvar tuberculosis in a postmenopausal woman with a history of asymptomatic pulmonary and pleural tuberculosis, with no prior documented contact with the bacillus. Diagnosis was based on vulvar lesion biopsies, with histological findings suggestive of infection and isolation of M. tuberculosis by microbiological culture and polymerase chain reaction (PCR) essays. The lesions reverted to normal after tuberculostatic therapy.

title: Competitive and cooperative incentives in dyadic relationships: a case study in the organic grape chain

description: Abstract Incentive systems aim to motivate and direct the behavior of participants in inter-organizational relationships. Cooperative incentives are based on sharing of benefits and gains generated in relationship, while the competitive ones refer to rewarding suppliers based on their performance relative to other suppliers. Based on the Relational View lens, the study aimed to analyze how competitive and cooperative incentives from the purchasing company influence the economic results of its suppliers. A qualitative research was carried out through a case study, whose unit of analysis was the dyadic relationship in an organic products supply chain. The results showed that the purchasing company uses competitive incentives when it seeks to encourage suppliers to adopt behaviors in order to avoid punishment, especially in relation to productive activities. Cooperative incentives also promote information exchange, knowledge transfer and trust-based relationships. As a theoretical contribution, in the organic production context, it was identified that beyond the influence of competitive and cooperative incentives over the relations between buyer and suppliers there are external factors such as international certification standards and regulations, which exerts a strong influence on the studied relation.

title: Burden, depression and anxiety in primary caregivers of children and adolescents in renal replacement therapy

description: ABSTRACT Introduction: Chronic kidney disease (CKD) is rare in children, but it causes repercussions in several aspects of life, because the disease and treatment cause great changes in the daily lives of the child and his family, increasing the burden on caregivers. Objective: To evaluate the burden of primary caregivers of children and adolescents who undergo renal replacement therapy (RRT). Methods: Cross-sectional, observational study performed at the Pediatric Renal Unit of a school hospital in the Northeast. Forty-nine primary caregivers of pediatric patients with CKD in RRT followed up in our clinic participated in the study. We used validated instruments to assess burden, depression and anxiety. We ran some tests to analyze the findings of burden, depression and anxiety in the sample. Results: Most of the caregivers are the mothers of these children (89.8%), aged between 36 and 45 years (46.9%), have Elementary School education only (55.1%) and reported feeling pain in the body (69.4%), but they did not have chronic disease. The majority of the children have been in RRT from 1 to 3 years (40.8%), aged from 9 to 11 years (30.6%), are male (55.1%), and under hemodialysis (38.8%). The caregivers had a moderate level of burden (2.10), a high prevalence of moderate to severe depression (18.4%) and anxiety (47%), and a strong correlation between burden, depression and anxiety. Conclusions: Caring for a child with CKD is an intense experience, with negative consequences, due to uncertainties about the future and the very care these children require. We need to do something to help these caregivers better manage care, as well as cope with their own feelings.

title: Descriptive analysis of spending on hospitalizations due to ambulatory care sensitive conditions

description: Abstract Background Funding is a problem present throughout the history of the Brazilian Unified Health System (SUS). Health spending in Brazil have always been insufficient to ensure the principles of SUS. Objective To analyze spending on hospitalizations due to ambulatory care for sensitive conditions (HACSC) and their impact on health expenditures. Method This study analyzed spending on health in São Leopoldo, RS, between 2003 and 2012. It is an ecological study using data available from the Informatics Department of Brazil’s National Unified Health System through the Hospital Information System and the Information System of Public Health Budget. Results São Leopoldo’s total health expenditure increased 70.91% in the period, growing 58.52% in per capita spending, and only 21.75% in expenses for primary health care (PHC). Spending on HACSC increased 16.30% and total spending with hospitalization decreased 3.54%. Compared to total health expenditure, the spending on HACSC represented 2.57%, in 2003, and 1.75%, in 2012. Comparing to expenses for PHC, the average spending on HACSC represented 19.43% of expenses on PHC. Conclusion There was an increase in per capita spending on health, but still insufficient. The amounts spent on the ICSAP could represent a significant savings to the health system.
