title: Symptomatic bradycardia due to nicotine intoxication

description: ABSTRACT Nicotine is a dangerous substance extracted from tobacco leaves. When nicotine is absorbed in excessive amounts, it can lead to respiratory failure and cardiac arrest. The commercialization of electronic cigarettes (e-cigarettes) has allowed users to directly handle e-cigarette liquid. Consequently, the risk of liquid nicotine exposure has increased. We describe our experience of managing the case of a patient who orally ingested a high concentration of liquid nicotine from e-cigarette liquid. The patient presented with bradycardia and hypotension, which are symptoms of parasympathetic stimulation, together with impaired consciousness. He recovered following treatment with atropine and a vasopressor.

title: Influenza A non-H1N1 associated with acute respiratory failure and acute renal failure in a previously vaccinated cystic fibrosis patient

description: ABSTRACT In the 2014 - 2015 season, most influenza infections were due to A (H3N2) viruses. More than two-thirds of circulating A (H3N2) viruses are antigenically and genetically different (drifted) from the A (H3N2) vaccine component of 2014 - 2015 northern and southern Hemisphere seasonal influenza vaccines. The purpose of this paper is to report a case of seasonal influenza A non-H1N1 infection that occurred in June 2015 in an adult cystic fibrosis patient with severe lung disease previously vaccinated with the anti-flu trivalent vaccine. The patient evolved to respiratory and renal failure (without rhabdomyolysis) and was placed under mechanical ventilation and hemodialysis. The clinical outcome was positive after 39 days of hospital stay. In addition, the patient was clinically stable after 18 months of follow-up. With the recent advances in critical care medicine and in cystic fibrosis treatment, survival with advanced pulmonary disease in cystic fibrosis presents new questions and potential problems, which are still being formulated.

title: Association between estimated glomerular filtration rate and sodium excretion in urine of African descendants in Brazil: a population-based study

description: ABSTRACT Introduction: Excessive salt intake is a risk factor for the development of chronic kidney disease (CKD). Objective: To evaluate the association between estimated glomerular filtration rate (eGFR) and sodium excretion in urine samples of Brazilians of African ancestry. Methods: Cross-sectional, population-based study of 1,211 Brazilians of African ancestry living in Alcântara City, Maranhão, Brazil. Demographic, nutritional, clinical, and laboratory data were analyzed. The urinary excretion of sodium was estimated using the Kawasaki equation. Calculations of eGFR were based on the Chronic Kidney Disease Epidemiology Collaboration equation. Multivariate linear-regression model was used to identify the relationship between sodium excretion and eGFR. Results: Mean age was 37.5±11.7 years and 52.8% were women. Mean urinary excretion of sodium was 204.6±15.3 mmol/day and eGFR was 111.8±15.3 mL/min/1.73m2. According to multivariate linear regression, GFR was independently correlated with sodium excretion (β=0.11; p&lt;0.001), age (β=-0.67; p&lt;0.001), female sex (β=-0.20; p&lt;0.001), and body mass index (BMI; β=-0.09; p&lt;0.001). Conclusions: The present study showed that age, female sex, BMI, and correlated negatively with eGFR. Sodium excretion was the only variable that showed a positive correlation with eGFR, indicating that high levels of urinary sodium excretion may contribute to hyperfiltration with potentially harmful consequences.

title: Chemistry Inspired by the Colors of Fruits, Flowers and Wine

description: ABSTRACT An overview is provided of the status of research at the frontiers of investigation of the chemistry and photochemistry of two classes of natural plant pigments, the anthocyanins and the betalains, as well as of the pyranoanthocyanin pigments formed from anthocyanins during the maturation of red wine. Together, anthocyanins and betalains are responsible for almost all of the red, purple and blue colors of fruits and flowers and anthocyanins and pyranoanthocyanins are major contributors to the color of red wines. All three types of pigments are cationic below about pH 3, highly colored, non-toxic, reasonably soluble in water or alcohol and fairly stable to light. They exhibit good antioxidant or antiradical activity and, as part of our diet, confer a number of important health benefits. Systematic studies of model compounds containing the basic chromophoric groups of these three types of pigments are providing a deeper understanding of the often complex chemistry and photochemistry of these pigments and their relationship to the roles in vivo of these pigments in plants. These natural pigments are currently being exploited as starting materials for the preparation of novel semi-synthetic dyes, pigments and fluorescence probes.

title: Appropriation of School Mathematics Discourses: considerations from the experience of an intercultural training of indigenous teachers

description: Abstract This paper focuses on the ways by which undergraduates of an Intercultural Training Course for Indigenous Teachers appropriate discursive practices of school mathematics, when they evaluate or develop educational proposals to mathematics teaching in the village school. From an empirical material produced when observing this course and adopting ethnographic procedures, we weaved an analysis that enhances the understanding of the processes of appropriation related to the problem of meaning and the question of participation in social practices. Thus, the way the educators in training manage the confrontation between discursive practices of different trends in the field of Mathematics Education and Indigenous Education outlines not only mathematics conceptions and its teaching in the indigenous school, but also possibilities of structuring and analyzing pedagogical proposals that they intend to adopt in their teaching activities.

title: Investigation of the cardiovascular risk profile in a south Brazilian city: surveys from 2012 to 2016

description: ABSTRACT The aim of this study was to investigate the cardiovascular risk profile of the participants recruited from stroke awareness campaigns in Santa Maria RS, Brazil, from 2012 to 2016, using the simplified version of the Framingham Risk Score (FRS). Questionnaires were used to evaluate 1,061 participants from 20 to 74 years old. Data on cardiovascular risk factors were obtained. The prevalence of risk factors and mean FRS for men and women were estimated. The FRS for women was 11.8% (moderate risk) and 24.7% for men (high risk). The vascular age for women was 61.6 years, whereas the vascular age for men was 66 years. Two percent of women had hypertension and diabetes, while both these risk factors were present in 5% of men. Based on the data, the prevalence of stroke risk factors is worrisome, as are the numbers of individuals with moderate and high cardiovascular risk in Santa Maria.

title: Geoprocessing used in the selection of areas for deployment of landfill in the municipality of Conceição das Alagoas (MG), Brazil

description: ABSTRACT Given the large amount of solid waste disposed in open dumps, contaminating the soil, the water and the air, there was a need to improve and adjust the final disposal of such waste. The main objective was to identify potential areas for the construction of a municipal landfill, in order to reduce the environmental impacts generated by incorrect disposal of this waste in the municipality of Conceição das Alagoas, Minas Gerais, Brazil. The methodology used in the survey of potential areas was based on a digital mapping using geographic information system techniques. In the first step, the surveys of restrictive and potential zones in the municipality of Conceição das Alagoas were conducted for the landfill implementation. In the second step, we evaluated all areas inserted in the potential zone, in which six areas were determined as suitable for the landfill deployment according to restriction criteria.

title: OxLDL plasma levels in patients with Alzheimer's disease

description: ABSTRACT Objective: The objective of this study was to characterize the conventional lipid profile, oxLDL levels and ApoE polymorphism in patients with Alzheimer's disease (AD) and in elderly individuals without cognitive impairment. Methods: Eighty elderly individuals were selected and the levels of oxLDL were determined using the ELISA kit, and ApoE gene polymorphism was investigated using polymerase chain reaction-restriction fragment length polymorphism. Results: Significantly reduced levels of oxLDL were observed in patients with AD compared to the control group. A higher frequency of the ApoE ε4 allele was observed in patients with AD compared to controls. No difference was observed for total cholesterol, HDL-C, and LDL-C levels between the two groups, while triglyceride levels were higher in controls compared with patients with AD. Conclusion: The data analyzed together did not reveal significant differences in lipid profiles, including oxLDL levels. However, the importance of lipid changes in the genesis of the disease cannot be ruled out. Nevertheless, the ApoE ε4 allele was significantly more frequent in patients with Alzheimer's dementia in agreement with previous findings in the literature, but this genetic component did not change the levels of oxLDL.

title: Using in situ flow cytometry images of ciliates and dinoflagellates for aquatic system monitoring

description: Abstract Short-period variability in plankton communities is poorly documented, especially for variations occurring in specific groups in the assemblage because traditional analysis is laborious and time-consuming. Moreover, it does not allow the high sampling frequency required for decision making. To overcome this limitation, we tested the submersible CytoSub flow cytometer. This device was anchored at a distance of approximately 10 metres from the low tide line at a depth of 1.5 metres for 12 hours to monitor the plankton at a site in the biological reserve of Barra da Tijuca beach, Rio de Janeiro. Data analysis was performed with two-dimensional scatter plots, individual pulse shapes and micro images acquisition. High-frequency monitoring results of two interesting groups are shown. The abundance and carbon biomass of ciliates were relatively stable, whereas those from dinoflagellates were highly variable along the day. The linear regression of biovolume measures between classical microscopy and in situ flow cytometry demonstrate high degree of adjustment. Despite the success of the trial and the promising results obtained, the large volume of images generated by the method also creates a need to develop pattern recognition models for automatic classification of in situ cytometric images.
