title: Phosphorus and nitrogen balance in constructed wetlands with Eichhornia crassipes (Mart.) Solms

description: ABSTRACT Improper disposal, even after treatment, of wastewater can cause negative impacts on receiving water bodies. Particularly, substances such as nitrogen and phosphorus can become, depending on their concentrations, toxic to aquatic organisms or produce favorable conditions for the proliferation of a vegetation that can start the process of eutrophication. Constructed wetlands are a wastewater treatment built to mimic the structure of natural wetlands, promoting mechanisms of phytoremediation. Despite E. crassipes be an invasive plant which causes problems in eutrophic lakes and rivers, its use may be interesting in wetlands because it is an ornamental plant, which will increase wastewater treatment system’s acceptance, and it can be reused in crafts, in biofuel production and in animal feed. In this context, the present study aimed to evaluate the efficiency of the retention/removal of total phosphorus and Kjeldahl nitrogen (TKN) present in wastewater by two subsurface horizontal flow constructed wetland system cultivated with Eichhornia crassipes, with a difference of 43 days of cultivation, fixed to a support medium. The concentrations of total phosphorus ranged from 4.5 to 5.1 mg.L-1 in the affluent and from 3.2 to 4.4 mg.L-1 in the effluent of constructed wetlands, whereas NTK concentrations ranged from 95.9 to 104.7 mg.L-1 in the effluent, and from 77.5 to 85.3 mg.L-1 in the effluent.

title: Oil blends with sesame oil in fish diets: oxidative stress status and fatty acid profiles of lambari

description: ABSTRACT The objective of this research was to evaluate the growth performance, oxidative stress, and fatty acid profiles of lambari (Astyanax altiparanae) fed diets containing different lipid sources: soybean oil, linseed oil, and freshwater fish residue oil combined or otherwise with sesame oil (SEO). The fish (mean weight 0.95±0.46 g; mean length 4.21±2.77 cm) were distributed into 24 cages (cage capacity: 0.70 m3; fish density: 276 individuals m−3) in six treatments and four replicates. After 80 days of feeding, they were weighed, and samples were collected for assay of catalase, glutathione reductase (GR), and lactate dehydrogenase (LDH) enzyme activities in muscle and analysis of the fatty acid profiles of polar and neutral fractions of whole eviscerated fish. The addition of SEO reduced docosahexaenoic acid (C22:6n-3, DHA) levels but increased the percentage of highly unsaturated n-3 fatty acids and the DHA: eiocosapentaenoic acid ratio, while reduced GR and LDH enzyme activities in muscle. Thus, certain blends of oils added to fish diets can improve the lipid profile of lambari and protect consumers against reactive oxygen species.

title: PRECORDIAL PAIN, LEUKOCYTOSIS AND BICYTOPENIA IN A TEENAGER WITH SYSTEMIC JUVENILE IDIOPATHIC ARTHRITIS UNDER IMMUNOSUPPRESSIVE THERAPY

description: ABSTRACT Objective: To highlight the importance of the new classification criteria for the macrophage activation syndrome (MAS) in systemic juvenile idiopathic arthritis in order to reduce morbidity and mortality outcome related to this disease. Case description: A 12-year-old female patient with diagnosis of systemic juvenile idiopathic arthritis under immunosuppression therapy for two years developed cough, acute precordial chest pain, tachypnea, tachycardia and hypoxemia for two days. Chest tomography showed bilateral laminar pleural effusion with bibasilar consolidation. The electrocardiogram was consistent with acute pericarditis and the echocardiogram showed no abnormalities. Laboratory exams revealed anemia, leukocytosis and increased erythrocyte sedimentation rate, as well as C-reactive protein rate and serum biomarkers indicative of myocardial injury. Systemic infection and/or active systemic juvenile idiopathic arthritis were considered. She was treated with antibiotics and glucocorticoids. However, 10 days later she developed active systemic disease (fever, evanescent rash and myopericarditis with signs of heart failure) associated with macrophage activation syndrome, according to the 2016 Classification Criteria for Macrophage Activation Syndrome in Systemic Juvenile Idiopathic Arthritis. She was treated for five days with pulse therapy, using glucocorticoids, immunoglobulin and cyclosporine A, with improvement of all clinical signs and laboratory tests. Comments: Myopericarditis with signs of heart failure associated with MAS is a rare clinical presentation of systemic juvenile idiopathic arthritis. Macrophage activation syndrome occurs mainly during periods of active systemic juvenile idiopathic arthritis and may be triggered by infection. Knowledge about this syndrome is crucial to reduce morbidity and mortality.

title: JUVENILE XANTHOGRANULOMA: A CASE REPORT

description: ABSTRACT Objective: To report a rate case of Juvenile xanthogranuloma in a newborn infant. Case description: We present the case of a 31-week preterm newborn with multiple skin lesions whose clinical, histological and immunohistochemical findings allowed the diagnosis of juvenile xanthogranuloma. Currently, the patient has nine months-old, and there is no aggravation of the skin lesions or evidence of extra-cutaneous involvement, particularly ophthalmic. Comments: Juvenile xanthogranuloma is a rare and benign condition, included in the vast group of non-Langerhans histiocytosis. It typically occurs in the pediatric age and may have a neonatal presentation. It affects predominantly the skin, in the form of papules or yellow and/or erythematous nodules and could be asymptomatic, multiple or solitary. Extra-cutaneous involvement, is more common in toddlers and when multiple lesions are present. The eye is the most affected site. We highlight this clinical case by its presentation in the neonatal period and in the form of multiple lesions, which bestows an increased risk of extra-cutaneous involvement, although this has not yet been verified.

title: AGENESIS OF THE POSTERIOR ARCH OF THE ATLAS: AN INCIDENTAL FINDING IN A POLYTRAUMATIZED PATIENT

description: ABSTRACT The first cervical vertebra is subject to numerous anatomical variations. One of these is posterior arch agenesis, which is classified into five distinct morphological types. Together, all types of posterior arch agenesis comprise only 4% of atlas variations. Furthermore, complete agenesis of the posterior arch associated with the presence of the posterior tubercle is rare. This work reports a case of posterior arch agenesis with the presence of the posterior tubercle in a 33 year-old male victim of a motor vehicle collision. Despite being asymptomatic, this anatomical variation can present with headaches and neck pain. It is mostly found as an incidental finding in imaging studies performed by the emergency team and, as a result, it is often misdiagnosed as a C1 fracture. Knowledge of the variations relating to the first cervical vertebra is therefore essential to avoid delays in diagnosis and treatment of polytraumatized patients. Level of evidence V; Case report.

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: PRECONCENTRATION BASED ON COPRECIPITATION USING SILVER CHROMATE AS A CARRIER FOR COPPER DETERMINATION BY FAAS

description: In the present paper, a preconcentration procedure based in the coprecipitation of copper by silver dichromate (Ag2CrO4) and consecutive determination by flame atomic absorption spectrometry (FAAS) was proposed. The experimental factors were optimized from application of the Doehlert matrix and the conditions set: chromate concentration 5.8 × 10-4 mol L-1, silver concentration 1.1 × 10-3 mol L-1, pH 7.3 and disperser concentration HNO3 0.38 mol L-1. Under these conditions, analytical parameters of the procedure were obtained, with the quantification limits of 0.76 µg L-1, precision (based in the relative standard deviation, RSD %) with values lower than 2.7%, and preconcentration factor of 28. The accuracy of the procedure was given by addition/recovery test in water samples groundwater and mineral, and by comparison with results obtained by ICP-MS. The procedure developed presented be simple, sensitive and low cost, thus can be applied in the preconcentration and determination of copper in several water samples.

title: Identification and analysis of enterprise risks associated with the value environment of the Cargill cocoa business

description: Abstract This article seeks to identify and analyze the enterprise risks associated with the value environment of Cargill’s cocoa business. It is a qualitative study using the case study method. To obtain a systemic perspective of the phenomenon, the data was collected by interviewing executives from different areas of the company, submitting their narrative to content analysis. Thus, from the perspective of enterprise risk management, it was identified that the main internal risks arise from cocoa processing, due to the high degree of complexity of the operations, and high added value of the products involved in the system. As for the external risks, the emphasis is on the relations with suppliers, as a result of the dependence of middlemen on the process of buying the raw material. It was also observed that political, legal and social aspects appear as points of attention and important sources of risk in this value system. These results contribute, therefore, to the advancement of the enterprise risk literature in business environments associated with the agribusiness context, while presenting the applicability of scientific models for the identification and classification of these risks. Future studies of a longitudinal nature and contemplating the risks of the chocolate value chain in its completeness are recommended.

title: Dabigatran and warfarin in nonvalvular atrial fibrillation or atrial flutter in outpatient clinic practice in Brazil

description: ABSTRACT Objectives: To compare warfarin and dabigatran for thromboembolic event prevention in patients with nonvalvular atrial fibrillation or atrial flutter. Methods: This was a retrospective cohort of participants with nonvalvular atrial fibrillation or atrial flutter using either warfarin or dabigatran in a reference center in Brazil. Results: There were 112 patients (mean age 65.5 years), with 55.3% using warfarin. The median duration of follow-up was 1.9 years for warfarin and 1.6 years for dabigatran (p = 0.167). Warfarin patients had a higher median of medical appointments per year (8.3 [6.8-10.4] vs 3.1 [2.3-4.2], p &lt; 0.001) and the frequency of minor bleeding was more than four times higher (17.7% vs 4.0%, p = 0.035). Among patients with prior stroke, those using warfarin had 2.6 times more medical appointments for person-years of follow-up (8.5 vs 3.3). There was no major bleeding or embolic event during follow-up period. Conclusion: The dabigatran group had a lower frequency of minor bleeding and number of medical appointments than the warfarin group, without more embolic events or major bleeding.

title: ALTERNATIVE TO THE INVERTED “Y” INCISION IN SCOLIOSIS SECONDARY TO MYELOMENINGOCELE

description: ABSTRACT Objective: To evaluate the healing of the modified inverted “Y” incision in patients with scoliosis due to myelomeningocele. Methods: Retrospective study through medical records review of patients with myelomeningocele surgically treated with a modified inverted “Y” approach between January 2013 and December 2015. Results: We analyzed the medical records of six patients. Two patients progressed with skin complications in the immediate postoperative period and only one of them required surgical intervention for debridement and suturing. In another patient, it was necessary to perform two surgical reviews due to material failure without skin complications in these interventions. Conclusions: The modified inverted “Y” technique is a great alternative to traditional incision and inverted “Y” because it has good results in patients with spina bifida associated with poor skin conditions treated surgically for correction of spinal deformities. Level of Evidence IV; Case series.
