title: Food intake of university students

description: ABSTRACT This narrative literature review aimed to analyze the results of studies on the food intake of university students. A literature search was conducted in July 2014 and updated in July 2016 in the Scopus, MedLine/PubMed, and SciELO databases, using descriptors related to university students and food intake in English and Portuguese. Overall, 37 studies that analyzed university students’ food intake were included in this review, eight of which were conducted in Brazil. The results demonstrated that most university students have unhealthy eating behaviors, such as high intake of fast foods, snacks, sweets, soft drinks, and alcoholic beverages, and low intake of fruits, vegetables, fish, whole grains, and legumes. Undergraduate students of health sciences, such as nursing, nutrition, and medicine, did not have healthier diets. University students’ food intake was characterized as unhealthy, regardless of undergraduate program or sex, especially among students who left the parents’ home and became responsible for their own food. Therefore, there is a need of developing public policies that promote healthy eating habits among students, such as interventions to change their eating habits and increase their access to healthy foods at the university environment.

title: Poisoning in children and adolescents notified at a toxicology center in the Northeast of Brazil

description: Abstract Objective: to analyze the clinical and epidemiological profile of poisoning in children and adolescents under 12years old. Methods: a crosssectional study with analytical component based on poisoning notifications at the Centro de Toxicologia de Pernambuco (Toxicological Center in Pernambuco), carried out in 2012 and 2014. Allergic reactions and contaminated food poisoning were excluded. Sociodemographic characteristics, type of toxic agent, circumstance, place of occurrence, time until care and patients' evolution were analyzed. The distribution of frequencies and associations among the variables through prevalence ratio and the chisquared test was determined. Results: Among 2,843 patients registered, 1,601 (56.3%) were poisoned by chemical substances and 1,242 (43.7%) by poisonous animals. Most lived in urban areas (90.6%) and were attended for care after an hour of the incident (47.6%). The poisoning frequency of chemical substances was higher among children under five years old (PR=2.34; CI95%= 2.142.56) and there was no difference in the sexes (PR=1.00; CI95%= 0.941.07). The predominant medicine (45.0%) for poisoning was between chemical substance and scorpions (77.0%). Poisoning occurred as accidental in 92.2% and 99.6% of chemical substance occurred at home. There were six deaths by chemical intake and two by scorpions.. Conclusions: poisoning in Pernambuco State is considered a public health issue given by its frequency and it occurred mostly with children under 5 years old accidentally and at home.

title: Molecular characterization of progenies of bacurizeiro ( Platonia insignis ) from Marajó Island, northeastern Amazon

description: ABSTRACT The bacurizeiro (Platonia insignis Mart.) is a tree native to the Amazon whose fruit is much used in the gastronomy in the North and Northeast regions of Brazil. Due to its great economic potential for these regions, the species is being conserved in germplasm banks to support genetic breeding programs. The aim of this work was the molecular characterization of P. insignis accessions belonging to the germplasm bank of the Embrapa Eastern Amazon research unit using ISSR (Inter Simple Sequence Repeat) markers. Seventy-eight accessions of P. insignis belonging to 16 progenies were sampled in two different localities on Marajó Island, state of Pará, Brazil. Among the 16 progenies, seven were collected in Soure and nine in Salvaterra. The 78 accessions were genotyped with 23 pre-selected primers. We obtained 121 amplified products, of which 54 were polymorphic. The most polymorphic primers were UBC 834, UBC 899 and UBC 900. Primers UBC810 and UBC884 did not amplify polymorphic bands. Forty-nine markers out of 54 were selected for genetic analyses. AMOVA within and among progenies showed low genetic differentiation (ΦPT = 0.064, P&lt;0.001) with higher diversity within progenies (96%), low genetic differentiation among sampling localities (ΦPT = 0.025, P&lt;0.013), and higher diversity within (98%) than among localities. Clustering by UPGMA based on Jaccard similarities among pairs of accessions did not separate genotypes according to progeny or sampling localitiy. We recommend that new germplasm surveys consider a greater sampling effort within sampling localitites.

title: INSTITUTIONAL PROGRAM OF TEACHING INITIATION (PIBID): PERFORMANCE OF FELLOWS VERSUS NON-FELLOWS

description: Abstract: We report the results of a study with the objective of comparing the academic performance of fellows from the Institutional Program of Teaching Initiation (PIBID) with non-fellows, considering (a) the concept of the courses in the National Student Performance Examination (ENADE) and (b) the turn of operation of these courses. The studied population consisted of 2,193 graduates of the Federal University of Ceará (UFC), referring to the period 2009.2 to 2015.1, of which 1,924 were not PIBID holders (87.7%) and 209 were PIBID scholarship holders (12.3 %). It was verified that the higher averages of academic performance were associated to the alumni graduates of PIBID, regardless of the concept of the course in the ENADE, as well as the turn of operation of this. The results demonstrated the relevance of the PIBID to the training of university students, since substantial differences were identified in the quality of the alumni’s learning, expressed by the higher performance averages, compared to the graduates who were not PIBID scholars.

title: Two mechanisms of oral malodor inhibition by zinc ions

description: Abstract Objectives The aim of this study was to reveal the mechanisms by which zinc ions inhibit oral malodor. Material and Methods The direct binding of zinc ions to gaseous hydrogen sulfide (H2S) was assessed in comparison with other metal ions. Nine metal chlorides and six metal acetates were examined. To understand the strength of H2S volatilization inhibition, the minimum concentration needed to inhibit H2S volatilization was determined using serial dilution methods. Subsequently, the inhibitory activities of zinc ions on the growth of six oral bacterial strains related to volatile sulfur compound (VSC) production and three strains not related to VSC production were evaluated. Results Aqueous solutions of ZnCl2, CdCl2, CuCl2, (CH3COO)2Zn, (CH3COO)2Cd, (CH3COO)2Cu, and CH3COOAg inhibited H2S volatilization almost entirely. The strengths of H2S volatilization inhibition were in the order Ag+ &gt; Cd2+ &gt; Cu2+ &gt; Zn2+. The effect of zinc ions on the growth of oral bacteria was strain-dependent. Fusobacterium nucleatum ATCC 25586 was the most sensitive, as it was suppressed by medium containing 0.001% zinc ions. Conclusions Zinc ions have an inhibitory effect on oral malodor involving the two mechanisms of direct binding with gaseous H2S and suppressing the growth of VSC-producing oral bacteria.

title: Randomized clinical trial of encapsulated and hand-mixed glass-ionomer ART restorations: one-year follow-up

description: Abstract Objective This prospective, randomized, split-mouth clinical trial evaluated the clinical performance of conventional glass ionomer cement (GIC; Riva Self-Cure, SDI), supplied in capsules or in powder/liquid kits and placed in Class I cavities in permanent molars by the Atraumatic Restorative Treatment (ART) approach. Material and Methods A total of 80 restorations were randomly placed in 40 patients aged 11-15 years. Each patient received one restoration with each type of GIC. The restorations were evaluated after periods of 15 days (baseline), 6 months, and 1 year, according to ART criteria. Wilcoxon matched pairs, multivariate logistic regression, and Gehan-Wilcoxon tests were used for statistical analysis. Results Patients were evaluated after 15 days (n=40), 6 months (n=34), and 1 year (n=29). Encapsulated GICs showed significantly superior clinical performance compared with hand-mixed GICs at baseline (p=0.017), 6 months (p=0.001), and 1 year (p=0.026). For hand-mixed GIC, a statistically significant difference was only observed over the period of baseline to 1 year (p=0.001). Encapsulated GIC presented statistically significant differences for the following periods: 6 months to 1 year (p=0.028) and baseline to 1 year (p=0.002). Encapsulated GIC presented superior cumulative survival rate than hand-mixed GIC over one year. Importantly, both GICs exhibited decreased survival over time. Conclusions Encapsulated GIC promoted better ART performance, with an annual failure rate of 24%; in contrast, hand-mixed GIC demonstrated a failure rate of 42%.

title: Incremental Prognostic Value of Conventional Echocardiography in Patients with Acutely Decompensated Heart Failure

description: Abstract Background: Acutely decompensated heart failure (ADHF) presents high morbidity and mortality in spite of therapeutic advance. Identifying factors of worst prognosis is important to improve assistance during the hospital phase and follow-up after discharge. The use of echocardiography for diagnosis and therapeutic guidance has been of great utility in clinical practice. However, it is not clear if it could also be useful for risk determination and classification in patients with ADHF and if it is capable of adding prognostic value to a clinical score (OPTIMIZE-HF). Objective: To identify the echocardiographic variables with independent prognostic value and to test their incremental value to a clinical score. Methods: Prospective cohort of patients consecutively admitted between January 2013 and January 2015, with diagnosis of acutely decompensated heart failure, followed up to 60 days after discharge. Inclusion criteria were raised plasma level of NT-proBNP (&gt; 450 pg/ml for patients under 50 years of age or NT-proBNP &gt; 900 pg/ml for patients over 50 years of age) and at least one of the signs and symptoms: dyspnea at rest, low cardiac output or signs of right-sided HF. The primary outcome was the composite of death and readmission for decompensated heart failure within 60 days. Results: Study participants included 110 individuals with average age of 68 ± 16 years, 55% male. The most frequent causes of decompensation (51%) were transgression of the diet and irregular use of medication. Reduced ejection fraction (&lt;40%) was present in 47% of cases, and the NT-proBNP median was 3947 (IIQ = 2370 to 7000). In multivariate analysis, out of the 16 echocardiographic variables studied, only pulmonary artery systolic pressure remained as an independent predictor, but it did not significantly increment the C-statistic of the OPTMIZE-HF score. Conclusion: The addition of echocardiographic variables to the OPTIMIZE-HF score, with the exception of left ventricular ejection fraction, did not improve its prognostic accuracy concerning cardiovascular events (death or readmission) within 60 days

title: THE USE OF ENGLISH EDUCATIONAL PORTALS IN ESP TEACHING AND LEARNING

description: ABSTRACT: Besides reading and writing, the learning and development of listening and speaking skills have affected and worried a great number of learners, especially in the ESP context. Some studies have focused their attention on finding these difficulties and proposing solutions that can perhaps minimize these problems. Aiming to contribute to the debate, this study investigates listening and speaking activities displayed in five English educational portals with the objective of identifying what kind of pedagogical tasks and exercises are suggested and their textual configuration in the digital context. The results revealed that the majority of activities can be considered as additional instructional materials which can be used in the classroom because of the relevant issues presented. However, to be used directly in the digital context these activities need to be reformulated and adapted to allow teachers and learners to use all the technological resources in an effective and functional way.
