title: Morphologic criteria of vermiform appendix on computed tomography and a possible risk of developing acute appendicitis

description: Abstract Objective: To evaluate the correlation of morphological criteria of the cecal appendix using computed tomography (CT) and the possible risk of developing acute appendicitis. Materials and Methods: Cases were defined as patients with surgically confirmed acute appendicitis who had undergone CT at least twice: at diagnosis and at least one month prior. Controls were defined as emergency patients with abdominal pain who had undergone abdominal CT that excluded acute appendicitis and had also undergone CT at least one month before. Results: 100 cases and 100 controls were selected for inclusion in the final analysis. Comparisons between the cases and controls revealed the following: mean transverse diameter of 0.6 cm (range, 0.4-1.0 cm) versus 0.6 cm (range, 0.6-0.8 cm; p = 0.37); mean length of 6.6 cm (range, 3.5-9.7 cm) versus 6.6 cm (range, 4.5-8.3 cm; p = 0.87); mean angle of 100° (range, 23-178°) versus 86° (range, 43-160°; p = 0.01); vertical descending orientation in 56% versus 45% (p = 0.2); absence of gas in 69% versus 77% (p = 0.34); and presence of an appendicolith in 17% versus 8% (p = 0.08). Conclusion: Hypothetical risk factors for obstruction of the vermiform appendix detected on CT were not associated with acute appendicitis. That suggests that factors other than those related to mechanical obstruction are implicated in the pathogenesis of acute appendicitis.

title: Comparison of Apgar score, serum lactate, and blood gas analysis in neonates born by elective cesarean section or cesarean section after dystocia

description: ABSTRACT: In some situations, the neonatal mortality rate in dogs can be high, and perinatal and postnatal veterinary care is essential to improve survival. This study to compared the Apgar score, serum lactate levels, and blood gas analysis results in 30 neonates born by elective cesarean section (GCE, n = 18) or cesarean section due to dystocia (GD, n = 12). Neonates were assessed at five time points: T0, at birth; T1, 3 h after birth; T2, 6 h after birth; T3, 12 h after birth; and T4, 24 h after birth. At T0, in the GCE group, 55.6% of the animals presented with adequate vitality, while 38.8% showed moderate changes in the Apgar score. In the GD group, 83.3% of the neonates had severe loss of vitality. At T1, none of the GCE neonates and 8.3% of the GD neonates presented with vitality deficits. Hyperlactatemia was observed in 83.3% of the GD neonates, and mixed acidosis (metabolic and respiratory) was observed at T0 in most neonates in both groups (GCE, 55.6%; GD, 72.7%). Compared to GCE neonates, the acid-base disorders were more severe and their recovery slower in GD neonates. At T0, GD neonates had higher hyperlactatemia and a lower Apgar score (worse vitality) than those of GCE neonates.

title: Hybrid multicriteria and economic engineering model to support decision in fleet management

description: Abstract Purpose: To provide the decision-making agency with a hybrid composite model for a qualified decision and maximize the quality of public management when challenged by the tradeoff between own and leased fleet. Originality/value: The proposed methodology innovates by integrating a framework based on a set of quantitative and qualitative criteria, increasing accuracy of the decision-making process regarding the management of the Ceára Public Safety Secretary’s fleet. With a multicriteria model, one can understand and identify the fundamental criteria in terms of management to select alternatives and avoid making these decisions based only on experience or feeling. Design/methodology/approach: To support the decision-making process regarding the choice or combination between own and leased fleet, optimal solutions are built using a hybrid model that combines techniques from the multi-attribute utility theory (Maut) models of economic engineering with the help of the total cost of ownership (TCO). The alternatives are weighted (considered) qualitatively and quantitatively through the proposed model. Findings: The results confirm the compatibility between the methods used, providing the agency with a methodological tool that qualifies the decision based on a model that reveals the decision-makers’ preferences in terms of relevant attributes to good management, while respecting budgetary constraints.

title: Enhancing Brand Understanding Through Brand Training: a Conditional Process Analysis of Recent Hires at an Airline

description: Abstract Purpose Within internal branding research, the positive association between employee brand training and brand understanding is well established. However, the boundary conditions of this focal relationship have not been researched to date, and insights about the effect of individual differences would be of significant practical value to service organizations. Accordingly, the purpose of this study is to test the moderating effect on the focal relationship of three key individual differences: age, gender, and customer-contact position. Theoretical framework The study is grounded on established constructs and relationships from the internal branding literature. Design/methodology/approach Data were collected at a Latin American airline using a web-based survey. The sample included 225 recently hired employees. The analysis was performed through conditional process models estimated with the PROCESS macro for SPSS. Findings Age moderates the focal relationship, with older employees displaying a weaker impact of brand training on brand understanding, which becomes non-significant after the age of 50. For gender, the moderating effect was not significant. Contact position had a significant negative effect on the focal relationship, i.e. brand training had a weaker impact on brand understanding for contact employees compared to non-contact employees. This is attributed to contact employees’ involvement in service encounters, which provides real-world opportunities to learn about the brand above and beyond formal brand training, opportunities which non-contact employees lack. Practical & social implications of research Training managers in service organizations can use the study results to achieve a greater impact from scarce brand training resources. For gender differences, the findings support a uniform allocation of training resources. For age differences, a differential allocation is advised, with more resources for younger employees, who have lower brand understanding scores and derive a greater impact from brand training. The finding of a diminishing impact of brand training suggests devising alternative means/opportunities for older employees to enhance their brand understanding. Lastly, the results support allocating more training resources to non-contact employees who, when compared to contact employees, have lower brand understanding scores, exhibit a higher impact of brand training, and have fewer non-training opportunities to learn about the brand. The result generalizability is limited by the sample coming from a single organization. Originality/value Within the internal branding research there is little examination of moderating effects for established relationships. This study makes an incremental contribution by testing the effect of three relevant individual differences on the relationship between brand training and brand understanding. The results have practical managerial applications.

title: Water uptake of soybean pods and seeds with different lignin contents

description: ABSTRACT The identification of pod- and seed-related traits of soybean genotypes and their interaction with water uptake can be applied in breeding programs with a view to establishing cultivars developed for the production and maintenance of high-quality seeds. The objective was to evaluate the water uptake of pods and seeds of soybean cultivars with different lignin contents after different soaking periods. The experimental was arranged in a completely randomized, 7×10 factorial design, with four replications. The factors consisted of seven soybean cultivars and 10 soaking periods (1, 2, 3, 4, 5, 6, 7, 8, 24, 48 hours). The pods and seeds were grown in a greenhouse and harvested at the phenological growth stage R8 (at full maturation, when 95% of the pods had mature color). The following traits were evaluated: lignin content in pod and seed coat, moisture content, and rate of water uptake of pods and seeds. Soybean cultivars with pods with high lignin contents have a lower rate of water uptake. The lignin contents of the seed coats, within the chosen limits, did not affect the seed water uptake.

title: Ultrasound elastography in the evaluation of thyroid nodules: evolution of a promising diagnostic tool for predicting the risk of malignancy

description: Abstract The elastic properties of tissue have always been of interest in clinical practice. In the past, the identification of structures that were stiffer on physical palpation would raise the suspicion that “there was something wrong”. With the development and advancement of medicine, there proved to be a true correlation in the prediction of malignancy of a lesion: malignant disease tends to stiffen the affected tissue, either by increased cell proliferation or fibrosis. Palpation is the oldest method for the detection of thyroid nodules, which is informed by the knowledge that malignant thyroid lesions tend to be much harder than benign ones. Unfortunately, palpation is a highly subjective method that is dependent on the size and location of the lesion, as well as on the skill of the physician. In cases where these nodules are very small or are located in deep regions, their detection by palpation is difficult or even impossible. In addition, although a malignant lesion differs in terms of elasticity, it may not have echogenic properties, preventing its detection by conventional ultrasound. Imaging that indicates the stiffness or deformation of tissues, through the use of ultrasound elastography techniques, adds new information related to their structural formation. In this article, we review the basic physical principles of elastography and the evolution of the method for the evaluation of thyroid nodules, as well as the limitations of and future perspectives for its use.

title: The added value of diffusion-weighted imaging in the preoperative assessment of endometrial cancer

description: Abstract Objective: To evaluate the added value of diffusion-weighted imaging (DWI) in the preoperative assessment of myometrial invasion in endometrial cancer, in comparison with T2-weighted imaging (T2WI) and dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI). Materials and Methods: This was a retrospective study involving 44 women with endometrial cancer who underwent preoperative 1.5 T MRI. Two radiologists, both of whom were blinded to the histopathology reports, performed a consensus interpretation of the depth of myometrial invasion and of the stage of the cancer, considering three sets of sequences: T2WI, DCE-MRI+T2WI, and DWI+T2WI. Accuracy, sensitivity, specificity, positive predictive value, and negative predictive value were calculated for each set. The accuracy was compared with p-value adjustment by the Benjamini-Hochberg procedure. Results: Among the 44 patients evaluated, DWI+T2WI demonstrated better diagnostic performance in assessing deep myometrial invasion and correctly staged more patients (n = 41) than did DCE-MRI+T2WI (n = 34) and T2WI (n = 22). The superior diagnostic accuracy of DWI+T2WI was statistically significant in comparison with T2WI (p &lt; 0.05) but not in comparison with DCE-MRI+T2WI (p &gt; 0.05). Conclusion: The addition of DWI apparently improves the diagnostic accuracy of MRI in the preoperative assessment of the depth of myometrial invasion in endometrial cancer, which may be particularly helpful in patients for whom contrast agents are contraindicated.
