title: Non-Linear Model to Describe Growth Curves of Commercial Turkey in the Tropics of Mexico

description: ABSTRACT The objective of this study was to select the best non-linear model that fits the growth curve of turkeys managed under the tropical conditions of Southern Mexico. Data from 481 Hybrid converter turkeys (236 females and 245 males) reared under commercial conditions typical of that region were used. Turkeys were given ad libitum access to feed and water. Body weight was weekly recorded from 1 day to 23 weeks of age. Five non-linear mathematical models (Brody, Gompertz, Logistic, von Bertalanffy and Richards) were chosen to describe the age-weight relationship. The Brody and Richards' models fail to converge. The best fitting model was chosen based on the average prediction error (APE); the multiple determination coefficient R2 and the Akaike information criterion (AIC). In both sexes, von Bertalanffy and Gompertz were the best models. The highest estimates of parameter A (mature weight) for both females and males were obtained with the von Bertalanffy model followed by the Gompertz and Logistic. The estimates of A were higher for males than for females. The highest estimates of parameter k (rate of maturity) for both females and males were, in decreasing order for the Logistic, Gompertz, and von Bertalanffy models. k values for female turkeys was higher than for males. The age at the point of inflection and body weight at the age of point of inflection varied with the model used. The largest values of TI and WI corresponded to the Logistic model. Between sexes, the largest TI and WI values corresponded to males. The best models to describe turkey growth were the von Bertalanffy and Gompertz models, because it presented the highest APE, R2 and AIC values.

title: DEHYDRATION AND SPRAYING OF BURITI PULP (Mauritia flexuosa L.): SHELF-LIFE EVALUATION

description: ABSTRACT The present study aimed to process buriti fruits by dehydration and spraying and to evaluate their shelf-life in polyethylene plastic packaging at different storage temperatures. The edible part of the fruit was dehydrated, crushed and sieved for granule diameter standardization, packaged in polyethylene plastic packaging and stored at different temperatures 24°C (Ambient), 4°C (Cooling) and -12°C (Freezer). Fresh and dehydrated fruits were analyzed for moisture, pH, acidity, total and reducing sugars, proteins, lipids, ashes, carbohydrates, energy, ß-carotene and retinol equivalent. Dehydrated and sprayed buriti was analyzed every 30 days for 150 days of storage for peroxide, acid and iodine indexes and also for microbiological parameters. The constituents that stood out both in fresh and dehydrated and sprayed fruits were: lipids, carbohydrates and consequently, energy and ß-carotene. In relation to shelf-life, all treatments presented good chemical and microbiological stability during the 150 days of storage period. It was concluded that dehydrated and sprayed buriti remained with good chemical and microbiological stability for at least 150 days of storage at temperatures of 4°C and -12°C. It is suggested that this product can be used as an ingredient in formulated foods aimed at supplementation of pro-vitamin A.

title: Consistency evaluation of values of weight, height, and body mass index in Food Intake and Physical Activity of School Children: the quality control of data entry in the computerized system

description: ABSTRACT: Introduction: The quality control of data entry in computerized questionnaires is an important step in the validation of new instruments. The study assessed the consistency of recorded weight and height on the Food Intake and Physical Activity of School Children (Web-CAAFE) between repeated measures and against directly measured data. Methods: Students from the 2nd to the 5th grade (n = 390) had their weight and height directly measured and then filled out the Web-CAAFE. A subsample (n = 92) filled out the Web-CAAFE twice, three hours apart. The analysis included hierarchical linear regression, mixed linear regression model, to evaluate the bias, and intraclass correlation coefficient (ICC), to assess consistency. Univariate linear regression assessed the effect of gender, reading/writing performance, and computer/internet use and possession on residuals of fixed and random effects. Results: The Web-CAAFE showed high values of ICC between repeated measures (body weight = 0.996, height = 0.937, body mass index - BMI = 0.972), and regarding the checked measures (body weight = 0.962, height = 0.882, BMI = 0.828). The difference between means of body weight, height, and BMI directly measured and recorded was 208 g, -2 mm, and 0.238 kg/m², respectively, indicating slight BMI underestimation due to underestimation of weight and overestimation of height. This trend was related to body weight and age. Conclusion: Height and weight data entered in the Web-CAAFE by children were highly correlated with direct measurements and with the repeated entry. The bias found was similar to validation studies of self-reported weight and height in comparison to direct measurements.

title: Hypothyroidism is a Risk Factor for Atrial Fibrillation after Coronary Artery Bypass Graft

description: Abstract Introduction: Few reports in the world have shown a differential effect of hypothyroidism in relation to morbidity and mortality following cardiac surgery. Objective: To determine the association between preoperative hypothyroidism, composite and disaggregated outcomes of mortality and complications in patients undergoing first-time isolated myocardial revascularization surgery. Methods: Historical cohort of patients undergoing myocardial revascularization between January 2008 and December 2014, with 626 patients included for evaluation of the composite and disaggregated outcomes of in-hospital mortality and complications (atrial fibrillation, surgical site infection and reoperation due to bleeding). A logistic regression model was used to determine the association between hypothyroidism and the onset of those outcomes. Results: Cohort of 1696 eligible patients for the study, with 1.8 mortality. Median age, female gender and prevalence of arterial hypertension were all significantly higher among hypothyroid patients. No differences were found in other preoperative or intraoperative characteristics. Hypothyroidism was associated with the presence of the composite outcome, RR 1.6 (1.04-2.4) and atrial fibrillation 1.9 (1.05-3.8). No association with mortality, infections or reoperation due to bleeding was found. Conclusion: Hypothyroidism is a disease that affects females predominantly and does not determine the presence of other comorbidities. Hypothyroidism is a risk factor for the onset of postoperative fibrillation in patients undergoing myocardial revascularization surgery. Postoperative care protocols focused on the prevention of these complications in this type of patients must be instituted.

title: Time Series Forecasting Methods and Hybrid Modeling both Applied on Monthly Average Wind Speed for Regions of Northeastern Brazil.

description: Abstract The objective of this work is to perform time series forecasts of wind speed in terms of monthly averages in the Brazilian Northeast. The following time-series models, Auto-Regressive Integrated Moving Average (ARIMA) and Holt-Winters (HW) were tested, as well as computational artificial intelligence with the use of Artificial Neural Networks (ANN). In addition, two hybrid models were tested, the first with a combination of the ARIMA and ANN models, which work in the literature, and the second is an attempt to combine HW and ANN models. The adjusted series obtained by the hybrid models, are efficient to follow the profile of the observed series of the study regions, with similarities to the data observed in terms of maxima and minima, thus indicating the capacity of the models to represent seasonalities. The calculation of error statistics involving the hybrid (HW and ANN) model obtained the lowest values in Fortaleza, São Luís and Natal, for example, with percent error values of 3.80%, 4.91% and 2.85%, respectively. The reduction of the statistical variables of errors by the hybrid models when comparing the use of the models (ARIMA, HW and ANN) separately may influence the predictions of expected wind velocities.

title: Prevalence of hemoglobin variants in quilombola communities in the state of Piauí, Brazil

description: Abstract Hemoglobin variants (Hb) result from mutations in globin genes, with amino acid substitution in the polypeptide chain. Among the most common structural variants are HbS, HbC, HbD and HbE. The S hemoglobin gene is a high frequency gene across America and Brazil, where it is more frequent in the Southeast and Northeast. The scope of this article is to investigate the presence of hemoglobin variants in 15 quilombos (fugitive slave communities) of Piaui. The sample was of 1,239 people and hemoglobin was screened by high-performance liquid chromatography (HPLC). A questionnaire was applied related to gender, ethnicity and consanguinity. Of the samples analyzed, 5.4% had AS sickle cell trait, while SS and SC sickle cell anemia showed a rate of 0.8%, with AC, AD and DD hemoglobin. Of the 1,069 Afro-descendants, 84 revealed hemoglobin abnormalities, 34 being male 53 being female. There were 13 consanguineous marriages among the 84 hemoglobin alterations. The study of hemoglobin variants in 15 former quilombo communities in the state of Piaui contributes to their education in health in the aspects of genetic inheritance of hemoglobin, a relevant public health issue, providing input for the implementation of the State Program of Sickle Cell Disease of Piaui.

title: The Effect of Treatment Strategy of Chronic Ischemic Mitral Regurgitation on Long-Term Outcomes in Coronary Artery Bypass Grafting

description: Abstract Objective: To investigate the mid- and long-term outcomes of case-based selective strategy of mitral ring annuloplasty during coronary artery bypass grafting in patients with coronary artery disease accompanied by chronic ischemic mitral regurgitation. Methods: 132 patients who were diagnosed ischemic moderate to severe mitral regurgitation undergoing coronary artery bypass grafting in the same center with the same surgical team were divided into 2 groups and investigated retrospectively. Patients undergoing simultaneous mitral ring annuloplasty and coronary artery bypass grafting were enrolled to group 1 (n=58), patients undergoing isolated coronary artery bypass grafting were enrolled in group 2 (n=74). Results: The mean age of the patients were 65.0 ± 9.4 years and 39 (29.5%) of them were female. Preoperative New York Heart Association (NHYA) class (P=0.0001), atrial fibrillation (P=0.006) and the grade of mitral regurgitation (P=0.0001) were significantly different between the groups. Hospitalization for heart failure was required in 6 (10.6%) patients in group 1 and 19 (27.1%) patients in Group 2 (P=0.02). Hospital mortality and one-month postoperative mortality occurred in 2 (3.4%) patients in Group 1 and in 4 (5.4%) patients in Group 2 (P=0.69). Clinical follow-up was completed with 117 (88.6%) patients. Conclusion: Mitral ring annuloplasty in addition to the coronary artery bypass grafting is associated with improved NYHA functional class, increased ejection fraction, decreased residual mitral regurgitation. Further studies are needed to clarify the role of combined surgery on long-term outcomes. With proper tools and according to the decisions made by heart teams, both management strategies can be safely performed.

title: Naturally Occurring Co-infection of Avian Leukosis Virus (subgroups A-E) and Reticuloendotheliosis Virus in Green Peafowls (Pavo muticus)

description: ABSTRACT Most of the neoplastic diseases affecting poultry have a viral etiology, such as Marek’s disease, avian leukosis/sarcoma and reticuloendotheliosis. In the present paper, histopathology and molecular methods were performed, in addition of necropsy and gross morphology evaluation, for the differential diagnosis of these diseases in two green peafowls (Pavo muticus). The affected birds showed non-specific signs, such as depression, anorexia, and diarrhea. At necropsy, diffuse enlargement by several times the normal size of the liver and the spleen was observed. In one of the birds, the liver presented white to grayish discoloration was present, and focal and nodular growths in the other bird. Grossly, the other visceral organs and the peripheral nerves were normal. Microscopically, most of the tumor cells were large and uniform with pleomorphic nuclei. The PCR analysis for Marek’s disease virus (MDV), avian leukosis virus (ALV), lymphoproliferative disease virus (LPDV), and reticuloendotheliosis virus (REV)based on their specific sequences showed the presence of ALV subgroups A-E and REV. According to these results, definitive diagnosis was co-infection of ALV and REV in naturally-infected green peafowls.
