title: Nitrogen sources on yield, mineral nutrition and bromatology of Cyclanthera pedate

description: ABSTRACT Caygua fruits (Cyclanthera pedata) are used both in cooking and for medicinal purposes. However, few studies on this species, considered a non-conventional vegetable, can be found in literature. This study aimed to assess the responses of caygua crop to green manure and mineral nitrogen fertilization, in relation to marketable fruit productivity, nutrient content in leaves and fruits and bromatological composition. The study was carried out in a randomized block design with four treatments and five replicates: 1) control (without nitrogen); 2) 60 kg ha-1 nitrogen (urea form); 3) green manuring using Cajanus cajans and 4) green manuring using Crotalaria juncea. The plots consisted of three caygua lines with four plants per line (spacing 2x1 m). In the treatments using green manure, three lines of these respective legumes were cultivated. We evaluated marketable fruit productivity, nutrient contents in fruits and leaves and bromatological composition of the fruits. Production of caygua fruits was higher in the treatment consisting of urea application (23.6 t ha-1), followed by Crotalaria juncea (15.6 t ha-1), Cajanus cajans (14.8 t ha-1) and control (9.2 t ha-1). Treatments did not influence the nutrient contents in fruits and leaves and the bromatological composition. However, in relation to higher productivity, the amounts of nutrients absorbed by plants and accumulated in fruits were higher in treatments using mineral fertilization due to the higher yield. The bromatological analysis of fruits showed considerable contents of crude protein and ether extract, highlighting the potential of this species to human diet.

title: Conservation of both hematocrit and liver regeneration in hepatectomies: a vascular occlusion approach in rats

description: ABSTRACT Background: Hepatectomies promote considerable amount of blood loss and the need to administrate blood products, which are directly linked to higher morbimortality rates. The blood-conserving hepatectomy (BCH) is a modification of the selective vascular occlusion technique. It could be a surgical maneuver in order to avoid or to reduce the blood products utilization in the perioperative period. Aim: To evaluate in rats the BCH effects on the hematocrit (HT) variation, hemoglobin serum concentration (HB), and on liver regeneration. Methods: Twelve Wistar rats were divided into two groups: control (n=6) and intervention (n=6). The ones in the control group had their livers partially removed according to the Higgins and Anderson technique, while the rats in the treatment group were submitted to BCH technique. HT and HB levels were measured at day D0, D1 and D7. The rate between the liver and rat weights was calculated in D0 and D7. Liver regeneration was quantitatively and qualitatively evaluated. Results: The HT and HB levels were lower in the control group as of D1 onwards, reaching an 18% gap at D7 (p=0.01 and p=0.008, respectively); BCH resulted in the preservation of HT and HB levels to the intervention group rats. BCH did not alter liver regeneration in rats. Conclusion: The BCH led to beneficial effects over the postoperative HT and serum HB levels with no setbacks to liver regeneration. These data are the necessary proof of evidence for translational research into the surgical practice.

title: Access to oral healthcare services of adolescents of a large-size municipality in northeastern Brazil

description: Abstract: The aim of this study was to describe and evaluate access to oral health services among adolescents enrolled in public schools of Campina Grande, Paraíba, Brazil, a large-size municipality in the Northeast of Brazil. An observational, descriptive, analytical, quantitative, and cross-sectional study was carried out through a school survey, in which four validated questionnaires were applied to 438 adolescents aged 12 to 19 years. Data were processed using the SPSS statistical software version 20.0, with bivariate analysis and multivariate analysis through Poisson regression. About 90.9% of adolescents reported having visited the dentist at least once; however, when considering the last 6 months, this percentage fell to 48.4%. Adolescents used private services (50.2%) or the public service (49.8%). About 70.6% of interviewees reported dental treatment (61.1%) as the main reason for seeking the service. Through multivariate analysis, it was observed that the demand for the service was higher among female adolescents (60.5%, p &lt;0.001); the other variables did not present statistically significant differences. In conclusion, the access to oral healthcare services reported by adolescents was good, but there is still a considerable part of this population with no access. Variables that presented significant associated with dental services were gender and toothache history, but only gender remained significant in the multivariate model.

title: Effect of ethanol-wet bonding on porosity and retention of fiberglass post to root dentin

description: Abstract: This in vitro study aimed to assess the effects of different pretreatments used to adapt glass-fiber posts cemented to root canals with different resin cements, regarding porosity percentage and bond strength. Twelve bovine incisor roots were prepared with Largo drills. After post space preparation, the specimens were randomized into two types of pretreatment groups (n = 3): water-wet bonding and ethanol-wet bonding. After the post were cemented, the roots were stored in 100% humidity at room temperature for 7 days. The samples were scanned by microcomputed tomography (micro-CT). Images were reconstructed by NRecon software, and CTAn software was used to analyze the porosity percentage (%) at the luting interface. Evaluation of the push-out bond strength was performed by serially cutting the roots, and submitting the slices to testing. Additionally, the resin cement post-gel shrinkage values (%) were measured using the strain-gauge method (n = 10). Data were analyzed by two-way ANOVA, Tukey's test and Student's t test (a = 0.05). The roots prepared with ethanol-wet bonding using RelyX™ U200 had significantly lower porosity in the coronal and apical thirds (p &lt; 0.05). The group prepared with ethanol-wet bonding using RelyX™ ARC presented better bond strength results in the coronal and apical thirds (p &lt; 0.05). RelyX™ ARC (0.97%) produced a higher post-gel shrinkage value than RelyX™ U200 (0.77%). Canals pretreated with ethanol-wet bonding presented better outcomes in regard to porosity percentage and push-out bond strength.

title: Phyllodistomum vaili(Plagiorchiida: Gorgoderidae) infecting Parupeneus rubescens (Perciformes: Mullidae): morphology and phylogeny

description: Abstract Knowledge of the Arabian Gulf fish’s parasite fauna is very poor. Until recently, only scattered reports from different locations are known for ecto- and endoparasites. Therefore, the present study aimed to investigate the digenean species that infects one of the most economically fish species in the Arabian Gulf, the rosy goatfish Parupeneus rubescens . One plagiorchiid species has been described, belonging to the Gorgoderidae family, and has been named as Phyllodistomum vaili Ho, Bray, Cutmore, Ward & Cribb, 2014 based on its morphological and morphometric characteristics. In order to accurately classify and characterize this plagiorchiid species, molecular analysis was carried out using both nuclear 18S and 28S rRNA gene regions and revealed that the present plagiorchiid species was associated with other species belonging to the Gorgoderidae family and deeply embedded in the Phyllodistomum genus, closely related to the previously described P. vaili (gb| KF013187.1, KF013173.1). The present study therefore revealed that the species Phyllodistomum is the first account as endoparasites from the rosy goatfish inhabiting the Arabian Gulf.

title: Statistical analysis of the design procedure used in reinforced concrete pipes

description: Abstract Structural design procedures are based on simplified hypotheses that attempt to approximate the actual behaviour. Depending on the adopted hypothesis, the design procedure may not satisfactorily describe the structural actual behaviour. Such condition occurs in the design of reinforced concrete pipes, where there are uncertainties related especially on the internal forces and the installation type of the pipe. Moreover, the main design hypothesis is that the cross section is plane and perpendicular to the deformed axis. Based on materials resistance principles it is known that this hypothesis is unsatisfactory to pipes with aspect ratio lower than ten. Note that the commercial reinforced concrete pipes usually present aspect ratio well below ten. In the light of the foregoing, the main objective of this paper is to analyse the accuracy of the design procedure for reinforced concrete pipes. Therefore, statistical processes were used to compare design values with experimental results. The comparisons in this paper showed that the design procedure results in oversized pipes.

title: Epidemiological and deontological aspects of traffic mortality in Roraima

description: Abstract This is a longitudinal and descriptive study evaluating epidemiological and deontological aspects of traffic mortality in Roraima by comparing data from the Legal Medical Institute of Roraima, the Violence and Accident Surveillance System and the Mortality Information System. Most of the victims were men (85.2%), brown-skinned (81.5%), living in an urban area (81.5%), single (66.7%), between 15 and 34 years old (54.9%). The most common injuries were contusion (96.2%) and fracture (75.5%). The body parts most affected were the head (69.8%), lower limbs (66%) and face (54.7%). The main cause of death was head trauma (43.4%). The comparison of data evidenced underreporting of traffic mortality in Roraima. Constant reflection is essential to establish ethical parameters for the professionals involved, and the integration between health agencies and the Legal Medical Institute is recommended to create a database to support policies adapted to the local reality.

title: Implications of domestic dogs in the epidemiology of Rickettsia parkeri strain Atlantic rainforest and Rangelia vitalii in Southeastern Brazil

description: Abstract This study aimed to evaluate the occurrence of diseases transmitted by Amblyomma ovale in 61 dogs monitored for three years through collections of ticks and blood, interviews, telemetry and camera traps in three areas of Serra do Mar State Park, Brazil. Blood samples were used to investigate infection by Rangelia vitalii by real-time TaqMan PCR and Rickettsia parkeri by IIFA. The collected ticks were submitted to conventional PCR to investigate the presence of R. parkeri . These data were compared with the monitoring results and interviews with the owners. Dogs considered as companion presented a risk of infection by R. parkeri strain Mata Atlantica 5.4 times higher than those not considered as companion (p = 0.009). Dogs that had at least one A. ovale collected during the campaigns had a 10 times higher risk of infection by R. parkeri strain Mata Atlantica than those who did not (p = 0.009). One dog positive for R. vitalii by real-time TaqMan PCR was parasitized by A. ovale frequently during monitoring. Sequenced ompaA - positive DNA samples had 100% identity of R. parkeri strain Mata Atlantica clone As106. From the findings, it is urgent to control domestic dogs around rainforests to reduce zoonoses transmission.

title: Educational Predictors for the Retention of Physicians in Remote and Unassisted Areas: a Narrative Review

description: Abstract: This is an international narrative review study, which had the objectives of identifying and understanding the determining educational aspects for the retention of physicians in remote and unassisted areas. Through search on databases, we selected ten articles about medical education institutions and programs that increased the recruitment and retention levels for their alumni in areas where there was shortage of professionals, which clarified the educational aspects associated to such results, and which were considered as predictors for the retention of physicians. The main predictors found were: selection processes that prioritized the admission of students who were previously linked to places where there was a shortage of physicians; the creation of curricular frameworks based on problem-based methodologies focused on local health issues, with an emphasis in primary care and Family and Community Medicine approaches; and the quality of the educational experiences, especially in the primary care environment in rural or remote areas, which, in turn, involve the educational trajectory and experience of professors, as well as the infrastructure and localization of the medical schools in strategic areas. The placement of school is such areas allow close proximity between the professors to the reality of the vulnerable communities. The results of the review still point out that the retention of physicians in unassisted areas demands the confrontation of social, cultural, economic and political factors, which frequently transcend the governability of educational institutions. They also reiterate the need for a wider conceptual uniformity among research studies in order to ensure more solid scientific evidence about the subject, and the importance of conducting studies that contemplate the Latin-American context, specifically Brazil, where the literature on the topic is still scarce.

title: High Incidence of Herpes Simplex Virus-1 in Cord Blood and Placenta Infection of Women in Southern Brazil

description: Abstract Objective Estimate the prevalence of human herpesvirus type 1 HSV-1 DNA in placental samples, its incidence in umbilical cord blood of newborns and the associated risk factors. Methods Placental biopsies and umbilical cord blood were analyzed, totaling 480 samples, from asymptomatic parturients and their newborns at a University Hospital. Nested polymerase chain reaction (PCR) and gene sequencingwere used to identify the virus; odds ratio (OR) and relative risk (RR) were performed to compare risk factors associated with this condition. Results The prevalence of HSV-1 DNA in placental samples was 37.5%, and the incidence in cord blood was 27.5%. Hematogenous transplacental route was identified in 61.4% from HSV-1+ samples of umbilical cord blood paired with the placental tissue. No evidence of the virus was observed in the remaining 38.6% of placental tissues, suggesting an ascendant infection from the genital tract, without replication in the placental tissue, resulting in intra-amniotic infection and vertical transmission, seen by the virus in the cord blood. The lack of condom use increased the risk of finding HSV-1 in the placenta and umbilical cord blood. Conclusion The occurrence of HSV-1 DNA in the placenta and in cord blood found suggests vertical transmission from asymptomatic pregnant women to the fetus.
