Item Associação de fatores individuais e familiares com o comportamento da criança na sedação odontopediátrica(Universidade Federal de Goiás, 2016-12-13) Machado, Geovanna de Castro Morais; Costa, Luciane Ribeiro de Rezende Sucasas da; http://lattes.cnpq.br/9906371509661305; Costa, Luciane Ribeiro de Rezende Sucasas da; Batista, Aline Carvalho; Sacono, Nancy Tomoko; Serra-Negra, Júnia Maria Cheib; Gonçalves, Ilda Machado FiúzaObjectives: Moderate sedation is indicated to control children’s behavior during dental care, reducing anxiety and maintaining the child's well-being. However, some sedated children do not present good behavior making it difficult to perform dental procedures. This study investigated the association of possible individual factors (temperament) and family (parents’ dental anxiety, parents’ pain catastrophizing and coping strategies adopted by parents) with the children’s behavior during dental treatment under moderate sedation. Methods: A total of 110 children/parents (<7 years), referred to sedation at Dental Sedation Center (NESO) of the Faculty of Dentistry of the Federal University of Goiás, for not have cooperated during dental care, and their parents, participated of this observational study of data from two clinical trials. Children had two appointments: clinical examination and tooth restoration, with local anesthesia and rubber dam, under moderate sedation. The restorative session was filmed for further evaluation of the children's behavior by trained and calibrated observers. The behavior was assessed using the Ohio State University Behavioral Rating Scale OSUBRS. Positive behavior was considered when the children presented 80% or more of the sum of the scores 1 and 2 (quiet or crying) during the entire session. The children’s stress was evaluated through the increased cortisol levels present in the saliva, collected in three moments: arrival, 25 min after local anesthesia, and 25 min after the end of the procedure. Children’s temperament was assessed through the Children’s Behavior Questionnaire (CBQ) answered by parents. Factors related to parents’ anxiety were thus evaluated: dental anxiety using Corah Dental Anxiety Scale; level of pain catastrophizing through the Pain-Catastrophizing Scale-parents; coping strategies through Brief COPE. Data were analyzed using descriptive statistics and the Chi-square test, Friedman, Wilcoxon, Mann-Whitney, Kruskal Wallis or t-test for independent samples. Results: More than half of the children displayed negative behavior (n = 60 54.5%). Temperament did not associate with the negative behavior of children. Extroversion/surgency (P = 0.03) and the subscales ‘activity level’ (P = 0.04), ‘impulsivity’ (P = 0.04) and ‘smiling/laughter’ (P = 0.01) differed between behavior groups, where children with positive behavior had higher scores than those who had negative behavior. In a sample of 42 children, 31 (73.8%) were reactive to stress during local anesthesia and temperament was not associated with increased levels of children’s stress. Dental anxiety and pain catastrophizing were not associated with negative children’s behavior. Parents of children with negative behavior had higher scores in maladaptive coping and Venting subscale, and lower scores in the Acceptance subscale. Conclusion: Coping strategies adopted by the parents explained, in part, negative or positive children´s behavior. These results have shown that parental coping strategies may have protective or destructive effects on children's behavior. Temperament was not associated with negative behavior and did not influence the children´s stress during the injection of local anesthesia. However, many children were stressed during this procedure, a fact that should be always considered by the professional who assist children under moderate sedation.Item Características de carcaça e carne e concentração de cortisol sérico em bovinos de diferentes grupos genéticos(Universidade Federal de Goiás, 2010-09-10) SANTOS, Aracele Pinheiro Pales dos; RESTLE, João; http://lattes.cnpq.br/7559938697233077; PADUA, João Teodoro; http://lattes.cnpq.br/0308044304591375The aim of this study was to evaluate carcass characteristics, meat and quantify the concentrations of cortisol in animals of different genetic groups finished in feedlot.We evaluated 32 non-castrated male cattle from four different genetic groups, being: Nellore (N), Aberdeen Angus x Nelore (AN), Caracu x Nelore (CN), Guzerat x Nellore (GN). The AN group steers had average daily gain (1.28 kg ± 0.15), weight (from 50.61 ± 627.50 kg) and hot carcass weight (335.87 kg ± 31.48) than the others. The carcass yield was similar between the AN group (53.50 ± 1.30%) and group N (52.50% ± 1.06). Carcass conformation was similar between the AN group (12.12 ± 1.35) and the CN group (10.87 ± 0.83) and physiological maturity was similar between the genetic groups. The AN group showed genetic superiority (P <0.05) compared to others in most of the features that express the musculature of the carcass, being superior in at least 5.4% in carcass length and 6.7% in cushion thickness . In measuring the loin eye area of housing, the AN group (85.09 ± 11.4 cm2) was similar to the CN group (74.50 ± 7.82 cm2) and GN (73.93 ± 14.14 cm2).For fat thickness measured in the housing group AN (5.68 ± 1.16 mm) was higher than other groups. In the assessment of carcass physical composition, the groups were similar in the proportion of muscle (PMU), proportion of bone (POS) and edible portion (PCO), but the proportion of fat (PGO) was similar between the groups AN, GN and N, with a correlation between the PMU and PGO -0.92. The shear strength analysis showed no significant difference between the genetic groups. There was no difference in the thawing water loss and water loss during cooking. For the cortisol values were not significant differences between groups for the collection 1, 2 and 4, but in collecting and killing three group N and AN showed significant differences.
