title: Actinic cheilitis: histopathological evaluation of 44 cases

description: Objective:To describe the epidemiological, clinical and histopathological aspects in actinic cheilitis.Material and method:We conducted a retrospective study from cases with clinical diagnosis of actinic cheilitis recorded in the histopathology of the Service of Head and Neck Napoleon Laureano Hospital, Paraíba, from 2000 to 2007. We selected 44 paraffin blocks to product new slides. These new sections were stained with hematoxylin and eosin, and histopathological evaluation was performed by two independent examiners, and the changes classified according to OMS. We conducted a descriptive statistical analysis in SPSS for Windows version 13.Result:Of the total sample, 52.3% (23) cases were diagnosed in men and 47.7% (21) in women aged from 27 to 92 years old. Most individuals (81.9%) were over 40 years old. Regarding the histologic features, 68.2% (30) of cases showed some degree of epithelial dysplasia, 36.3% (16) classified as mild dysplasia, 20.4% (9) moderate dysplasia and 11.3% (5) severe dysplasia. In 15.9% (7) cases, squamous cell carcinoma of lip was observed. In epithelial tissue lining lips, the most frequent histologic findings identified were the presence of hydropic degeneration (79.5%) and hypergranulosis (56.8%). Inflammatory infiltrate was observed in 88.6% of cases and 86.4% in solar elastosis.Conclusion:Based on the results of the sample we can conclude that most of the actinic cheilitis lesions fastened lower lip of men over 40 years old. Histopathological analysis revealed that cellular atypia, inflammatory infiltrate and presence of solar elastosis are common features in actinic cheilitis lesions.

title: Evaluation of equations for estimating the consumption of dairy cows

description: SUMMARY The present study aimed to perform a comparison of the predictive power of different equations to estimate intake by dairy cows. The work was conducted through collecting information in literature about body weight, milk yield, days in milk, dry matter intake and fat content of milk of dairy cows raised in Brazil. All this information, with the exception of dry matter intake, were used to predict the dry matter intake with equations of the model: National Research Council (NRC, 2001), Cornell Net Protein and Carbohydrate System (CNCPS, 2004), Agricultural and Food Research Council (AFRC, 1993) and De Freitas et al. (2006). Subsequently, the predictive power of the mathematical equations was compared through the graphical comparison of the standard as Draper and Smith (1966) and Montgomery (2005) and by means of Akaike's criterion (Akaike, 1974) waste. NRC (2001) was the best choice for presenting the ERr = 1, all others showed ERr much greater than 20 and therefore must be considered worse choices. AFRC (1993) has tended to underestimate the predicted values with 76% points above the line of invalidity. Model NRC (2001) is the one that best predicts the dry matter intake of dairy cows under the conditions studied.

title: Collaborative study to evaluate of the crude protein content in feeds using the “Kjeldahl” method

description: SUMMARY A collaborative study was conducted to evaluate the crude protein (CP) content in feeds in seven feed analysis laboratories from institutions linked to the National Institute of Science and Technology in Animal Science (INCT-CA). Were evaluated four samples of different feeds (sugarcane, corn silage, soybean meal and corn grain) and four nitrogen compounds assumed as standards (urea, monobasic ammonium phosphate, ethylene diamine tetraacetic acid and ammonium sulfate) to measure the accuracy of the estimates. Each laboratory analyzed the samples for six days, consecutive or not, with three replicates per sample per day of evaluation. The variances among laboratories and within of laboratories (repeatability) represented 34.5 and 10.3% of the total variation, respectively. The evaluation of nitrogen recovered from the standards showed that 25% of observations presented a significant bias (P&lt;0.001). The overall assessment of the samples demonstrated significant variations (P&lt;0.001) in function of the day of analysis, interaction of material with laboratory, and among laboratories. Additionally, it was found that the variation among laboratories corresponded of 43.6 to 68.2% of the total of random variation, while the repeatability (intra-laboratory variation) represented of 11.9 to 42.8% of reproducibility. The CP contents estimated are dependent of the interaction effect of the evaluated material and laboratory, which reflect the differences between the procedures utilized by each laboratory.

title: Germination of Psidium friedrichsthalianum (O. Berg) Nied. seeds under different temperature and storage conditions

description: Abstract: Psidium friedrichsthalianum is a species whose fruit can be used to make juices, jellies/jams and sweets, and its seedlings serve as rootstocks with resistance to Meloidogyne spp. The aim of this study was to evaluate the performance of seeds of this species at different germination temperatures, and to verify the effects of different moisture levels on their storage in two experiments. In the first, six germination temperatures (15, 20, 25, 30, 35, and 40 ºC) were evaluated, and in the second, seeds with different moisture levels (15.4, 9.8, 9.0, 8.4, and 8.2%) were stored in sealed containers at 20 °C for 0, 1, 3, 6, 9, and 12 months. Seed germination was favored by temperatures of 20 ºC and 25 ºC, reaching 93% and 87%, respectively, along with the highest germination speed indexes (2.582% day1 and 2.568% day-1) and shortest germination times (37.9 and 36.9 days). Temperatures of 30 °C and 35 °C maintained the seeds quiescent, while 40 °C was lethal. In storage, the seeds tolerated desiccation to 8.2% moisture content and could be stored in sealed containers at 20 ºC for 12 months, with germination higher than 70%.

title: Mapping of Environmental Fragility in the Aldeia Velha River Basin, State of Rio de Janeiro, Brazil

description: ABSTRACT This paper presents an approach to mapping the environmental fragility of river basins. The study was performed at the Aldeia Velha river basin, a rainforest watershed located between Rio de Janeiro’s coastal plains and the Serra do Mar highlands. A multiple-criteria analysis was performed involving factors that affect the risk of erosion; these variables were analyze using GIS tools and were integrated by algorithm in order to form a description of the different classes of environmental fragility in the basin. The multicriteria analysis considered the use of a numerical land model, official data, orbital imagery and the opinion of subject-matter experts. A Map of Potential Fragility (MPF) was generated through the collection of secondary information such as soil types, rainfall intensity and terrain slope. This initial map was later combined with a land-use projection to produce a Map of Emerging Fragility (MEF). The mapping results pointed to a highly fragile environment, where more than 70 percent of the basin’s area was classified with high or very high degree of fragility, in both the potential and emerging context. The Apparent Erosion Processes (AEP) were positively correlated in the areas with a higher level of fragility in the final map products, as well as highlighted the locations most prone to the intensification of erosion processes. The models generated important information for land-use planning, enabling affordable and easy upgrade for municipal governments and civil society organizations to monitor high fragility areas.

title: Numerical analysis of reinforced concrete asymmetric cross-section beams under oblique bending

description: Abstract The problem of symmetric cross-section beams under oblique bending is well known to professional designers and academy. In fact, symmetric elements make up most of the cross-sections defined in design. The case of the asymmetric cross-sections is, however, little discussed in literature, but is a particular problem, especially in bridge girder design, joined in loco. The asymmetry generates oblique bending when the load is out of the principal inertia planes. Thus, this article presents a comparison of results between a numerical solution of the elastic curve differential equations, and a Finite Element Model (FEM), for a 10m span reinforced concrete beam, with gutter-shaped asymmetric cross-section, whose only load is its own weight. The required geometric properties were determined by the Green Theorem. From theoretical study, the elastic curve differential equations were obtained, in the vertical and horizontal directions. The angular displacement conditions at the beginning of the span were obtained by the Virtual Work Method. After integration using the Runge-Kutta Method, the maximum displacements in the vertical and horizontal directions, in the middle span, are 0.904cm and 0.611cm, respectively (1.091cm resultant displacement). The Finite Element Model was performed in ANSYS 9.0. The resultant displacement of the numerical model was 1.16cm. Concurrently, the axial stresses were studied in the middle span. The stress results for both approaches (Runge-Kutta and FEM) differed by no more than 8.72%. These results guarantee reliability to the Runge-Kutta integration, from a design view point, to the proposed problem analysis in Serviceability Limit State.

title: Implementation of an Acute Coronary Syndrome Simulation Training Strategy for Emergency Healthcare Professionals

description: Abstract Background: The knowledge on the management of patients with acute coronary syndrome (ACS) is essential to reduce the gap between evidence and practice. Objective: To describe a simulation training strategy for emergency healthcare professionals and provide preliminary data on knowledge acquisition, learners' confidence and prescription of medications after training. Methods: The training was part of the implementation of two myocardial infarction systems of care. It comprehended lectures and simulation-based learning using high and low-fidelity mannequins and actors. It was tested in two phases: the first one in Belo Horizonte and the second one in Montes Claros, both in the state of Minas Gerais. A test was applied before and after training to assess knowledge acquisition. Confidence to perform thrombolysis in ST-elevation myocardial infarction (STEMI) patients was assessed using a questionnaire, and the impact on medication prescription analyzed STEMI patients admitted to hospitals in Montes Claros. Results: In the first phase, 156 professionals answered both tests: 70% of them improved their results and the median number of right answers increased (6, interquartile range [IQR] 5-7; vs 7 ([IQR] 6-9; p &lt; 0.05). In the second phase, 242 professionals answered both tests: 58% of the physicians and 83% of the nurses obtained better test scores. Participants referred a positive impact on their clinical practice, 95% reported feeling very secure when perform fibrinolysis after the training, and there was also an impact on medication prescription. Conclusions: There was an impact on the learners' knowledge acquisition and confidence using our two-phase training model, with evidence of impact on performance.

title: Occupational genetic mapping: axiological prospecting, bioethics and Brazilian legislation

description: Abstract This work aims to verify the status of Brazilian legislation on genetic mapping, focusing on the occupational sphere, in comparison to international legislation, to assess the country’s normative reality regarding social trends related to the recognition of differences and prospective legal opening. This is a review of literature and documents regarding the dialogue between bioethics, occupational medicine and genetics, taking into account that they have human dignity as a common ground. It was concluded that there is a tendency to accept the genetic mapping of workers for research and prevention of illness. Given their common reference and in accordance with the culturalist perspective of the Civil Code, it is inferred that this possibility extends to the genetic identification of workers’ skills for the exercise of their duties.

title: Factors associated to the immunization verification following hepatitis B vaccine among primary care workers

description: Abstract Introduction The verification of immunization following Hepatitis B vaccination is a simple procedure that offers security to the worker and should be a routine action among Primary Health Care workers. However, there is still a lack of discussions on this subject of remarkable relevance. This study aimed to investigate the prevalence of verification of immunization after vaccination against hepatitis B among workers of Primary Health Care and their association with occupational factors, overall health and self-care measures. Methods a cross-sectional study evaluating a sample of 400 workers, with confidence and precision of 95%, between August and December 2011, in the northern city of Minas Gerais. Bivariate analysis and Poisson regression were performed using the Statistical Package for the Social Sciences version 17.0. Results We observed immunity in 25.8% of the 400 workers vaccinated for hepatitis B. Factors associated with the verification were related to the team, working arrangements, contact with biological material and job satisfaction (p&lt;0.05). We found lower prevalence among contract workers and lower education (p&lt;0.05). Conclusion the verification of immunization is not set as routine, we observed a lower rate among contract workers with less training, showing neglect of occupational health.
