title: Early and late neuropathological features of meningoencephalitis associated with Maraba virus infection

description: Maraba virus is a member of the genus Vesiculovirus of the Rhabdoviridae family that was isolated in 1983 from sandflies captured in the municipality of Maraba, state of Pará, Amazônia, Brazil. Despite 30 years having passed since its isolation, little is known about the neuropathology induced by the Maraba virus. Accordingly, in this study the histopathological features, inflammatory glial changes, cytokine concentrations, and nitric oxide activity in the encephalon of adult mice subjected to Maraba virus nostril infection were evaluated. The results showed that 6 days after intranasal inoculation, severe neuropathological-associated disease signs appeared, including edema, necrosis and pyknosis of neurons, generalized congestion of encephalic vessels, and intra- and perivascular meningeal lymphocytic infiltrates in several brain regions. Immunolabeling of viral antigens was observed in almost all central nervous system (CNS) areas and this was associated with intense microglial activation and astrogliosis. Compared to control animals, infected mice showed significant increases in interleukin (IL)-6, tumor necrosis factor (TNF)-α, interferon (INF)-γ, MCP-1, nitric oxide, and encephalic cytokine levels. We suggest that an exacerbated inflammatory response in several regions of the CNS of adult BALB/c mice might be responsible for their deaths.

title: Histological Changes in Category 2 Animal Byproducts under the Influence of a Ferment Preparation

description: Abstract The paper deals with the possibility of processing category 2 animal byproducts with a ferment preparation. We chose collagen-rich cattle lips and ears as the category 2 byproducts for our study. The selected samples were processed in the following sequence: fixation, rinsing with running water, densifying the samples, slicing into sections, dying sections, and enclosing the sections under cover glass. The pathohistomorphologic changes found in the control samples significantly differ both before the processing and after the use of the ferment preparation Protepsin, which caused destructive metabolic and hydrolytic processes in the dense connective tissue of the ear and lip framework and led to softening of the muscle parenchyma of the organs.

title: Behavioral response of Biomphalaria glabrataexposed to a sublethal concentration of Euphorbia miliivar. hislopii latex

description: Abstract The Euphobia milii var. hislopii latex has been tested in the control of schistosomiasis but its action in the locomotor activity of Biomphalaria glabrata is unknown. The objective of this work was to study the locomotor and reproductive behaviors of B. glabrata exposed to E. milii var. hislopii latex. For this, 96 snails were individually exposed to the latex (LC50 - 0.53 mg / L) for 24 hours. The specimens were submitted to biomonitoring for image analysis to record the locomotor parameters at different times: before exposure (control), one day post exposure (group 1 d-p-e) and 30 days post exposure (group 30 d-p-e). The reproductive parameters were recorded weekly for 10 weeks. All locomotor activities of group 1 d-p-e decreased significantly. The egg/egg mass ratio decreased the week after exposure while there was an increase in the hatching rate. After 30 days, these reproductive parameters were similar to those observed in these same snails before exposure. However, the number of hatched snails declined after exposure until the end of the experiment. The influence of the latex in the parameters of B. glabrata added further evidence that this natural water-soluble product can be an important tool for the control of schistosomiasis.

title: Health promotion in schools: speeches, representations, and approaches

description: ABSTRACT Objectives: to analyze speeches, representations, and approaches on health and health promotion in schools, materialized in the speech of teachers. Methods: a qualitative study, of the case study type, carried out with 17 teachers from the municipal and state educational network. The data were obtained from interviews and analyzed by the Content-Oriented Discourse Analysis. Results: medical-sanitary and clinical-biological discourses predominated. Health is represented as the absence of disease, reflecting approaches that prioritize healthy habits and changes in behavior. Problematization of social determinants occurs in projects, in an intersectorial partnership. Final Considerations: carrying out projects of health promotion in schools ignores the solidification of partnerships and the construction of new speeches that represent it as quality of life conditioned by social, economic, and cultural factors as well as strategies for the ideological repositioning of those actors who act in this setting.

title: Bryophyte communities across the ecological succession process in the Caxiuanã National Forest, Pará, Brazil

description: Abstract Bryophytes play an important role in the process of ecological succession: conditioning the environment favourably for the emergence of subsequent groups. The objective of this study was to investigate the distribution of bryophyte communities in a cronossequence in the Caxiuanã National Forest, Pará, Brazil. To this end, biological material was collected in forest remnants with different successional stages based on regeneration age: Stage I (0 – 10 years), Stage II (10 - 25), Stage III (&gt; 25) and Stage IV (primary forests). Density, richness and composition of species were compared between successional stages and the occurrence of possible indicator-species was investigated. The identified taxa were also classified by guilds of tolerance to solar radiation and colonized substrate. Composition of species was the variable that most contributed to understanding the distribution of bryophyte communities throughout successional stages, with eight species identified as potential indicators of some successional stages. Generalist species predominated in all stages. The richness of sun tolerants, in turn, decreased with the progress of succession, while shade tolerants increased. The land use history and land cover can influence the availability and quality of substrates and consequently their colonization by bryophytes in the different stages.

title: Private health insurance coverage-related lawsuits

description: ABSTRACT Objectives: to analyze lawsuits brought by beneficiaries of health insurance operators. Methods: this was a cross-sectional descriptive study carried out in a large-capacity private health insurance operator using data collected by the company from 2012 to 2015. Results: ninety-six lawsuits were brought by 86 beneficiaries regarding medical procedures (38.5%), treatments (26.1%), examinations (14.6%), medications (9.4%), home care (6.2%), and other types of hospitalization (5.2%). The procedures with the highest number of lawsuits were percutaneous rhizotomy; chemotherapy; treatment-related positron-emission tomography scans; and for medications relative to antineoplastic and Hepatitis C treatment. Conclusions: the lawsuits were filed because of the operators’ refusal to comply with items not established in contracts or not regulated and authorized by the Brazilian National Regulatory Agency for Private Health Insurance and Plans, refusals considered unfounded.

title: Factors associated with the discontinuance of outpatient follow-up in neonatal units

description: ABSTRACT Objectives: to identify predisposing and enabling factors as well as the health needs associated with the discontinuance of outpatient follow-up of newborns who were hospitalized at neonatal intensive care unit. Methods: cross-sectional study, using the behavioral model of health services use. The study was composed of 358 mothers and newborns referred to the outpatient follow-up after discharge. Characterization, perception of social support, postnatal depression, and attendance to appointments data were collected, analyzed by the R software (3.3.1). Results: outpatient follow-up was discontinued by 31.28% of children in the first year after discharge. In multiple regression analysis, the chance of discontinuance was higher for newborns who used mechanical ventilation (OR = 1.68; 95%CI 1.04-2.72) and depended on technology (OR = 3.54; 95%CI 1.32-9.5). Conclusions: predisposing factors were associated with the discontinuance of follow-up; enabling factors and health needs did not present a significant association. Children with more complex health conditions require additional support to participate in follow-up programs, thus ensuring the continuity of care.

title: Associated factors with uncontrolled glycemic status in diabetic patients treated in the Unified Health System in Southwest of Bahia

description: Abstract Background Diabetes mellitus is an important public health issue, responsible for great morbidity and significant public health burden. A glycated hemoglobin, which assessed mean blood glucose in the past sixty days, has been an important tool in preventing comorbidities. Objective To evaluate the prevalence of glycemic and metabolic uncontrolled and associated factors used in the central laboratory of southwest Bahia Method This is a cross-sectional study conducted with 352 diabetic patients treated at the Laboratory of the Unified Health System. Results The study demonstrated more than two thirds of the patients (70.2%) described lack of glycemic control. Multivariate analysis showed that receiving fewer visits from community health workers OR 1.96 (1.05 - 3.65) and not have comorbidities associated OR 1.86 (1.05 - 3.30) were associated with poor glycemic control. Conclusion The results suggested the need to improve patient care with a health team sensitive to the practices for better metabolic control. The best action of the health team can contribute to health promotion and better quality of life for patients and impact on the reduction of health costs by reducing hospitalizations and procedures related to diabetes complications.

title: In vitro callus induction and development of Vernonia condensata Baker with embryogenic potential

description: ABSTRACT Vernonia condensata Baker has been traditionally used in folk medicine for the treatment of several inflammatory and infectious processes. Overexploitation of this plant species has drastically reduced its population in its natural habitat (Cerrado). Therefore, tissue culture tools, such as somatic embryogenesis, can be used as an alternative method for rapid and large-scale plant regeneration. The objectives of this study were to induce callogenesis in Vernonia condensata from different types of explants and to evaluate the structural aspects of the development of pro-embryogenic masses of this species by means of histological analyses. The formation of calli was induced from leaf explants and internodal segments, which were inoculated in EME medium supplemented with 50 g L-1 sucrose, 0.5 g L-1 malt extract and 2.68 μM NAA, plus varying concentrations of BAP (0.00, 2.22, 4.44 or 8.88 μM). After 40 days, the following morphogenetic traits were evaluated: intensity of callus formation, intensity of oxidation, callus texture, and morphogenesis. The calli with embryogenic masses were analyzed by light and scanning electron microscopy. Both types of explants were responsive regarding callogenesis, with the BAP concentration of 4.44 μM promoting the formation of friable calli associated with a larger percentage of calli with embryogenic masses. Cells from leaf explants and internodal segments were able to dedifferentiate and change into embryonic structures.

title: Nutritional status and physiological parameters of maize cultivated with sewage sludge

description: ABSTRACT The use of sewage sludge as a source of nutrients and organic matter for agricultural soils is a well-established practice. However, few reports highlight the effect of the nutrients and potentially toxic elements provided by organic wastes application on the plant physiological parameters, such as photosynthetic activity and stomatal conductivity. We performed a greenhouse experiment with maize exposed to a dystrophic red Latosol amended with mineral fertilizer and different rates of sewage sludge with the following objectives: i) assess the nutrients and metal uptake translocation and distribution in plants and ii) evaluate the relationship between plant physiological parameters and yield indicators under the study conditions. The application of sewage sludge increased the soil organic matter, pH, and the amounts of available Ca, S, and Mg, comparing to the mineral fertilizer treatment. The plants promote a higher translocation of macronutrients to the shoots in the sewage sludge treatments, which results in higher photosynthetic activity, stomatal conductivity, and maize yield parameters. Moreover, the trace elements, which can cause toxicity in small concentrations, were founded mainly in the roots, which indicates a plant defense mechanism.

title: Thermodynamic properties of moisture desorption isotherms of ryegrass (Lolium multiflorum L.) seeds

description: ABSTRACT Studies about the thermodynamic properties of ryegrass seeds are necessary to improve post-harvest processes, relating the factors that affect product quality with the interaction between water and its chemical components. Given the importance of recognizing and understanding the intrinsic behavior of water in ryegrass seeds and providing data for the improvement of industrial drying equipment, this work aimed to calculate and evaluate the thermodynamic properties of moisture desorption of ryegrass seeds as a function of the equilibrium moisture content. Ryegrass seeds with initial moisture content of 10.4 (% d.b.) was used. The equilibrium moisture content of seeds was determined by static-gravimetric method at different temperatures (10, 20, 30, 40, and 50 °C) and water activity values (between 0.10 and 0.90), in three repetitions. The Chung Pfost model presented the best fit to the experimental data. It was observed that the integral isosteric desorption heat increased as the equilibrium moisture content decreased, ranged from 2499.95 to 4241.96 kJ kg-1 in the moisture content range 2.80 to 22.10 (% d.b.). Differential entropy also increased with decreasing equilibrium moisture content, as did Gibbs free energy, being positive for all temperature studied, indicating that ryegrass seeds desorption is a non-spontaneous process. The enthalpy-entropy compensation theory was satisfactorily applied to the sorption phenomenon, being controlled by enthalpy.
