title: Predictors of Placebo Response and Remission in Ulcerative Colitis and Crohn’s Disease

description: Ulcerative colitis (UC) and Crohn’s disease (CD) are types of inflammatory bowel disease which affects over 300,000 Canadians. UC affects the large intestine and is characterized by diarrhea, rectal bleeding, abdominal pain, and urgency. CD can affect any area along the gastrointestinal tract, although many patients present with disease in the ileum and colon and experience symptoms including abdominal pain, weight loss, and diarrhea (3). Treatments for UC and CD must demonstrate efficacy and safety to obtain regulatory approval. Clinical trials for UC and CD are designed to assess the effect of a treatment and are often placebo-controlled when assessing novel biologic drugs. Placebo treatments do not contain any ingredients of therapeutic value and are often considered ‘sugar pills’. Despite receiving placebo, patients may still experience an improvement in their condition. Although high placebo response rates in clinical trials have been previously reported, it is unclear what factors may influence the response rate. Previous meta-analyses for UC have suggested factors such as disease duration, severity of disease as determined by endoscopy, rectal bleeding score at baseline, and class of treatment may play a role in placebo response and remission rates (3). The primary objective of this study is to evaluate predictors of clinical response among patients who received placebo treatment. This analysis will improve the design of clinical trials as smaller sample sizes (i.e. fewer patients required in the placebo arm of trials) can reduce the cost and improve trial efficiency. This could lead to reduced time to approval and market availability of novel therapies that can help patients suffering from UC and CD. Participant-level data of patients who received placebo from multiple clinical trials will be pooled and analyzed.

title: Base Saturation on Growth and on Nutrition of Yellow Ipê Seedlings

description: ABSTRACT Yellow ipê (Tabebuia serratifolia) is a forest species with wood potential, but little used in forest plantations because of the lack of information about their production both in the nursery and in the field. Therefore, an experiment was conducted in order to verify the effects of liming on growth and nutrition of T. serratifolia. The lime was mixed with soil dystrophic Red Oxisol with sand loam texture in plastic bags with capacity of 2.5kg. The treatments were in a completely randomized design with five repetitions: control 26.5%; 60%; 70%; 80% e 100% base saturation. After 120 days, were evaluated: height, stem diameter, height and diameter relation, dry biomass and Dickson quality index. The dried plants were submitted to determination of macronutrients content. The better results for growth of T. serratifolia were observed on the level of 70%, mainly because N, K, Ca and Mg were available in adequate concentrations, allowing the increase.

title: Risk factors for Charcot foot

description: Objective Diabetes mellitus is the main cause of Charcot neuroarthropathy and is clinically classified as follows: Charcot foot, acute Charcot foot (ACF) when there is inflammation, and inactive Charcot foot when inflammatory signs are absent. The aim of this study was to identify the risk factors for ACF in patients with type 2 diabetes mellitus.Materials and methods A matched case-control study was conducted to assess the factors associated with acute Charcot foot from February 2000 until September 2012. Four controls for each case were selected 47 cases of ACF and 188 controls without ACF were included. Cases and controls were matched by year of initialization of treatment. Conditional logistic regression was used to estimate matched odds ratios (ORs) and 95% confidence intervals (95% CIs).Results In multivariate analysis, patients having less than 55 years of age (adjusted OR = 4.10, 95% CI = 1.69 – 9.94), literate education age (adjusted OR = 3.73, 95% CI = 1.40 – 9.92), living alone (adjusted OR = 5.84, 95% CI = 1.49 – 22.86), previous ulceration (adjusted OR = 4.84, 95% CI = 1.62 – 14.51) were at increased risk of ACF. However, peripheral arterial disease (adjusted OR = 0.16, 95% CI = 0.05 – 0.52) of 6.25 (1.92 – 20.0) was a protective factor.Discussion The results suggest that PCA in type 2 diabetes primarily affects patients under 55 who live alone, are literate, and have a prior history of ulcers, and that peripheral arterial disease is a protective factor.

title: Establishment of Native Species Through Direct Seeding in Piauitinga River - Sergipe

description: ABSTRACT The direct seeding technique stands out for forest restoration projects due to savings in deployment costs and has been increasingly used. This work was carried out with the objective of assessing emergence, survival and establishment of native forest species, by means of seeds, in riparian areas of Piauitinga River, in the municipality of Lagarto-SE. The species used were Libidibia ferrea var. leiostachya (Benth.) L.P.Queiroz., Cassia grandis L.F., Cecropia pachystachya Trec., Enterolobium contortisiliquum (Vell.) Morong and Guazuma ulmifolia Lam. The field work was performed in a randomized block design (RBD) with four replications in factorial scheme, testing five species with and without treatment for overcoming of dormancy. It was observed that direct sowing is a viable technique for the area of study only for the species L. ferrea var. leiostachya, E. contortisiliquum and Cassia grandis, using seeds with and without dormancy.

title: The style variation in different reading situations: Capixaba variety

description: Abstract The style, along with linguistic and social resources, integrates the study of sociolinguistic variation. Based on W. Labov perspective, who mainly focused on the attention that the speaker pays to his/her own speech when he analysed stylistic variation, this research aims to observe possible stylistic differences between sentence reading (type “Digo palavra baixinho”) and text reading (type children's tale). The parameters analysed for such purposes are the frequencies of the first an second formants (F1 and F2) of stressed and pre-stressed vowels, the duration of those vowels (Dur) and their spectral emphasis (SE). The result confirmed that different styles promote different reactions in readers: the decontextualized sentences reading produced a more monitored speach than the text reading.

title: Diametric Distribution Projection of Ecological Groups in a Mixed Tropical Forest

description: ABSTRACT This study aimed to evaluate the ecological and successional aspects of a subtropical forest fragment by projection of the diameter distribution of different ecological groups, using transition matrix model. Based on measurements of 2009 and 2012 of all trees above 10 cm of DBH, projection of the diameter distribution as well as analysis of forest dynamic were made for three species groups: Pioneer; Non Pioneers, and the whole forest. Simulations of the dynamics of the groups were made until 2027 after method validation. The projection method was adherent in all cases, with higher precision when using the 5cm class interval. The analysis made indicated a gradual substitution tendency of the pioneer species, suggesting a successional advance in the forest fragment under study, as well as an efficiency of the projection method for dynamics analysis of the ecological groups studied.

title: Eucalyptus Litter Capacity of Stock and Water Retention

description: ABSTRACT This research aimed to evaluate the stock and water retention of 15 litter clones and hybrids of the species Eucalyptus, with three years of age. Samples of 1m2 of accumulated litter were collect by repetition. Each sample was separated into fractions consisting of twigs, leaves and amorphous material. The fractions were dried in a forced air kiln until they reached constant weight and, then the dry mass was determined. The water retention capacity was evaluate using the technique established by Blow in 1955. There were no significant differences reagrding litter stock, however, average accumulation was 4.96 Mg.ha–1 and variation between 3.34 to 4.96 Mg.ha–. Fractions contributed in the following descending order: leaf&gt; amorphous material&gt; twigs. Water retention capacity average (WRC) was 249.58%, the value was significantly lower to S-0208, S-0303 and S-0412 clones. The fractions contributed in decreasing order: amorphous material&gt; leaves&gt; twigs. Despite the significant difference between the fractions of WRC, all contribute to total water retention litter.

title: Spatial Variability and Sampling Structures for Forest Fuel Material Estimation

description: ABSTRACT The aim of this work was to model the spatial dependence of fuel material deposition on the ground in a pine stand, and to simulate and evaluate sampling procedures for estimating it. Branches with diameters up to 0.7 cm (A) and from 0.71 to 2.5 cm (B) were collected. Subsequently, the structures of systematic sampling and linear clusters were simulated for 50%, 33% and 23% of the total sample size, and the spatial dependence was evaluated through geostatistical modeling. The systematic sampling was suitable, with representative spatial coverage and accurate estimators, whereas linear clusters were inadequate. The reduction of the number of sample units affected the estimators, but their sampling errors did not exceed 10% for the sample sizes of 23% for class A of fuel material and 50% for class B in the systematic structure, resulting in consistent estimates.

title: Quantifying mean grades and uncertainties from the ratio of service variables: accumulation to thickness. Applied to a phosphate deposit in Southern Mato Grosso, Brazil

description: Abstract Estimating mineral resources of a stratiform mineral deposit is not always a simple activity. Some difficulties can arise in mineral deposits where the thickness is relatively much smaller than the dimensions in the horizontal plane, or because these deposits have suffered events after their genesis, such as thrusts and folds. Usually, in these cases, we use a new variable named accumulation as a product between the average grade and thickness. Then, from these service variables, accumulation and thickness are estimated in a regular grid. Dividing accumulation by thickness, we have the mean grade. However, the mean grade is just an approach because the uncertainties of variables are not considered in this division. This calls for applying the Taylor series to computing, not only the mean grade, but also the associated uncertainty. In this article, we present the satisfactory results of this method applied to quantify the mean grades and uncertainties of the blocks to a stratiform phosphate deposit located in southern Mato Grosso, Brazil.

title: Litterfall and Nutrient Input in a Degraded Area

description: ABSTRACT This study aimed to test the effects of fertilization with organic compost from industrial production of pulp on the litterfall and nutrient input of monospecific plantations in a loan area. The treatments consisted of three doses of the organic compost D10, D15 and D20 (10, 15 and 20 Mg ha-1, respectively), mineral conventional fertilization (DAM) and no fertilization (D0) in land plots (N = 4/treatment/species; 15 x 12 m). Litterfall was monthly collected by two traps (0.72 m2/plot) and sorted out into leaves, twigs, seeds, flowers, fruits and others. We determined the input of nitrogen, phosphorous and potassium. There were no differences among the treatments and between species in terms of total annual litterfall. The higher nutrient input was obtained by DAM, followed by D10, in both plantations. The annual nutrient input was higher for the litterfall on the E. urograndis plantation.

title: Anencephaly: knowledge and opinion of gynecologists, obstetricians and pediatricians in Goiânia

description: Abstract In order to analyze the knowledge and opinion of physicians about anencephaly, a cross-sectional study was performed, including 70 obstetrician-gynecologists and pediatricians of two hospitals in Goiania, Brazil. The interviewees answered a survey of 20 true or false closed questions. Their opinions were evaluated through a 5-subject questionnaire, with 31 affirmations with a Likert-type response scale. Most of the interviewees (70%) affirmed to have attended classes on anencephaly. The average of correct answers was 13.17. The assertive questions with the highest percentage of correct answers were on anencephalic pregnancy (80%) and the distinction between anencephaly and brain death (72%). The questions with the lowest number of correct answers were about the donation of anencephalic born alive babies’ organs (35%) and about the legislation that permits pregnancy termination when anencephaly had been unequivocally diagnosed (47.1%). Among those heard, 30.41% agreed on the fact that anencephalic babies have life. In conclusion, anencephaly is still a controversial topic and physicians need to acquire more knowledge on the subject.
