title: Prevalence of Maternal Morbidity and Its Association with Socioeconomic Factors: A Population-based Survey of a City in Northeastern Brazil

description: Abstract Purpose To identify the prevalence of maternal morbidity and its socioeconomic, demographic and health care associated factors in a city in Northeastern Brazil. Methods A cross-sectional and population-based study was conducted, with a design based on multi-stage complex sampling. A validated questionnaire was applied to 848 women aged between 15 and 49 years identified in 8,227 households from 60 census tracts of Natal, the capital of the state of Rio Grande do Norte (RN), Brazil. The main outcome measure was maternal morbidity. The Poisson regression analysis, with 5% significance, was used for the analysis of the associated factors. Results The prevalence of maternal morbidity was of 21.2%. A bivariate analysis showed the following variables associated with an increased number of obstetric complications: non-white race (prevalence ratio [PR] =1.23; 95% confidence interval [95%CI]: 1.04-1.46); lower socioeconomic status (PR = 1.33; 95%CI: 1.12-1.58); prenatal care performed in public services (PR = 1.42; 95%CI: 1.16-1.72): women that were not advised during prenatal care about where they should deliver (PR = 1.24; 95%CI: 1.05-1.46); delivery in public services (PR = 1.63; 95%CI: 1.30-2.03); need to search for more than one hospital for delivery (PR = 1.22; 95%CI: 1.03-1.45); and no companion at all times of delivery care (PR = 1.25, 95%CI: 1.05-1.48). The place where the delivery occurred (public or private) and the socioeconomic status remained significant in the final model. Conclusion Women in a worse socioeconomic situation and whose delivery was performed in public services had a higher prevalence of maternal morbidity. Such an association reinforces the need to strengthen public policies to tackle health inequalities through actions focusing on these determinants.

title: Prediction of genetic gains with selection between and within S2 progenies of papaya using the REML/Blup analysis

description: Abstract: The objective of this work was to predict the genetic gains with selection of superior individuals within papaya (Carica papaya) progenies using the REML/Blup analysis. Thirty-six S2 progenies, originated from the Calimosa and Tainung 1 hybrids, and two commercial control checks were evaluated in a randomized complete block design, with four replicates. The following traits were evaluated: heights of plants and first fruit; stem diameter at 12 and 18 months; number of days required for fruiting; number, mass, and average mass of commercial fruit; and number and mass of carpelloid and pentandric fruit. The magnitudes of the genetic parameters indicated that the variability present in most of the characters allows greater genetic gain if the selection is made at the progeny level, and not in individual plants. For selection among progenies, PROT-268, PROT-74, PROT-55, and PROT-22 were the most promising, with the greatest genetic gain for the studied characters. In the selection among and within progenies, the prediction of the gains is higher for the increase in the expression of the number of commercial fruit and for the decrease in the expression of pentandric fruit.

title: Incidence of musculoskeletal injuries in professional soccer players from Aracaju/SE-Brazil.

description: Abstract AIMS To verify the incidence of injuries in professional soccer athletes in Aracaju-SE and to identify associated factors. METHODS This was an observational, prospective cohort study involving 39 healthy athletes, followed for seven months and evaluated on four occasions (start on preseason and two evaluations with three months of interval between each) through data collection sheet and orthopedic physical examination. RESULTS Participants were 20 athletes from Club Sportivo Sergipe and 19 from Associação Desportiva Confiança, with mean age of 26 years (CI 95%: 25.2-28 years), and mean career time of 9.6 years (CI 95%: 7.9-11.3 years). The 13 (2.4 / 1000 hours) diagnosed injuries occurred almost exclusively in the lower limbs and thigh muscle stretch was the most common injury. Injuries were mostly mild to moderate (69%). There was no significant association with any of the variables analyzed. CONCLUSION Low incidence of injuries was observed in this study. Predominantly, lesions occurred on non-rainy days and were due to trauma. Lower limbs were the most affected location and thigh stretch was the most common injury.

title: KINETIC AND THERMAL DECOMPOSITION STUDIES OF RIGID POLYURETHANE FOAMS MODELED BY ARTIFICIAL NEURAL NETWORKS

description: Kinetic models of solid thermal decomposition are traditionally used for individual fit of isothermal experimental data. However, this methodology presents unacceptable errors in some regions of the data. To solve this problem, a neural network was adopted in this work. The implemented algorithm uses the rate constants as predetermined weights between the input and intermediate layer and kinetic models as activation functions of neurons in the hidden layer. The contribution of each model in the overall fit of experimental data is calculated as the weights between the intermediate and output layer. In this way, the phenomenon is better described as a sum of kinetic processes. Two rigid polyurethane foam samples: loaded with Al2O3 and no inorganic filler were used in this work. The R3 and D2 models described the thermal decomposition kinetic process for all temperatures for both foams with smaller residual error. However, the network, combining the kinetic models, presented residual errors on average 102 times lower compared to these individual models. The determined activation energy is 12.44 kJ mol-1 higher for the loaded foam. This result corroborates the use of this material as flame retardant, even with the presence of a small amount of charge in its structure.

title: Yield performance of soybean and corn subjected to magnesium foliar spray

description: Abstract: The objective of this work was to evaluate the effect of magnesium foliar spray on yield performance of soybean (Glycine max) and corn (Zea mays) cultivated in soil with adequate levels of base saturation and magnesium content in Brazil. The field trials were conducted on a Typic Hapludox cultivated with soybean and corn in the 2013/2014 and 2014/2015 crop seasons, respectively. Treatments consisted of Mg rates (50, 100, 250, 500, 1,000 and 1,500 g ha-1 and a control without Mg) applied during the V4, R1, and R5.1 (soybean) or V4 and R2 (corn) phenological growth stages as magnesium sulfate heptahydrate (MgSO4∙7H2O). The SPAD index, leaf Mg content, grain yield, and 100-grain weight were evaluated. The Mg foliar spray increased the SPAD index in soybean and the leaf Mg content in corn. The Mg rates of 540 and 890 g ha-1 increased in 325 and 737 kg ha-1 the yield performance of soybean and corn, respectively, regardless of the phenological growth stages. The Mg application during the reproductive stages increased in 2% the 100-grain weight for both crops. Foliar spraying of Mg improves the yield performance in soybean and corn crops.

title: Motor control assessment of community-dwelling older adults with depressive symptoms

description: Abstract AIMSThe purpose of this study was to investigate how depressive symptoms mediate different motor control requirements in elderlies and to assess the concurring effects fomented by the interaction between aging and depressive symptoms, providing indirect measures of brain functionality. METHODS Sixty-eight elderlies were paired in terms of age and gender and were equally distributed into depressed and nondepressed groups, according to their score on the Beck Depression Questionnaire. The participants performed the Grooved Pegboard Test placing and withdrawing pegs while execution time and error rate were measured. RESULTS This investigation revealed that depressive symptoms exert a broad effect upon motor control, although that the symptom intensity, as well as the interaction between aging and depression intensity, were exclusively correlated with withdrawal task, suggesting that there is a greater effect upon motor acts with higher frontal lobe requirements. CONCLUSION The discrimination of motor control aspects provides a valuable contribution for the understanding of the underlying neurophysiology of the interaction between aging and depression as it represents an indirect measure of cerebral dysfunction. Further, these findings may still have clinical implications, as they can promote more rational approaches to the elaboration of preventive measures that help maintain the functional capability of depressed elderlies.

title: HIGH PRESSURE BEHAVIOR OF CRYSTALLINE DIHYDROXYLAMMONIUM 5,5'-BISTETRAZOLE-1,1'-DIOLATE: FIRST-PRINCIPLES STUDY

description: Density functional theory (DFT) periodic calculations were performed to study the geometrical and electronic structures of energetic compound dihydroxylammonium 5,5'-bistetrazole-1,1'-diolate (TKX-50) under the pressure ranging from 0 to 400 GPa. The optimized crystal structure by the local density approximation (LDA) with CA-PZ functional matches well with the experimental values under the ambient pressure. When the structural transformations occur under the pressure of 126, 288, and 334 GPa, with the pressure increasing, the lattice constants, unit cell volume, total energy, interatomic distances, bond angles, atomic charges, and bond populations of TKX-50 change gradually. First of all, TKX-50 is rearranged in the crystal and the improvement of the molecular planarity occurs. Next, structural transformation appears with the distortion of the tetrazole rings. Finally, the rotation of molecular conformation occurs. The results of the band gap and density of states show that TKX-50 crystal, with the increase of pressure, undergoes an electronic transition from the semiconductor to the metallic system. These results provide basic information for the high pressure behavior of crystalline TKX-50.

title: Pain during tracheal aspiration in patients with traumatic brain injury undergoing mechanical ventilation

description: ABSTRACT BACKGROUND AND OBJECTIVES: Victims of traumatic brain injury, in intensive care units, frequently experience pain. Tracheal aspiration is a procedure with nociceptive potential routinely carried out in these patients. The objective of this study was to evaluate the effectiveness of tracheal aspiration in patients with traumatic brain injury undergoing mechanical ventilation. METHODS: Prospective study conducted in two intensive care units of a general public hospital in Aracaju, Sergipe, Brazil. During three days, 300 observations were carried out in 20 victims of traumatic brain injury. The pain was assessed using the Brazilian version of the Behavioral Pain Scale and the physiological parameters of heart rate and blood pressure (systolic and diastolic). The sedation depth was measured by Ramsay scores and the Richmond Agitation Sedation Scale. The Friedman test, ANOVA, and the Bonferroni post hoc test were used to verify the existence any differences in pain scores and physiological parameters at the different moments of the evaluation. A 5% statistical significance was accepted. RESULTS: The sample was predominantly comprised of men, young, from the interior of the State, with no comorbidities and with severe traumatic brain injury. Fentanyl and midazolam were the most used drugs for sedation and analgesia. There was a high prevalence of pain (70.0-85.5%). The pain scores were significantly higher during the tracheal aspiration, and the physiological parameters did not present any statistically significant increase. CONCLUSION: Valid and trustworthy behavioral scales, as the Behavioral Pain Scale, should be incorporated into the routine of the intensive care units to guide analgesia and sedation management, especially to prevent suffering during these painful procedures.
