Effects of Jugular Vein Occlusion on Cardiovascular Parameters in Horses During Exercise on a Treadmill

The purpose of the present investigation was to examine the effects of unilateral and bilateral jugular vein occlusion by temporary surgical ligature on the heart rate and arterial and venous blood pressure in sedentary horses during progressive treadmill exercise. Six horses performed three exercise tests (ET). ET1, considered the control, was performed in horses without jugular occlusions. ET2 and ET3 were performed with unilateral and bilateral occlusion by temporary surgical ligature of the jugular veins, respectively. Heart rate, arterial pressure, and pressure of the occluded jugular vein were evaluated. Clinically, the horses presented apathy, head edema, congested mucous membranes, increased capillary refill time, and dysphagia. These signs were observed with the unilateral jugular vein occlusion and became more evident with the bilateral occlusion. Comparing ETs, no differences were observed in heart rate. However, jugular occlusions promoted a decrease in the mean arterial pressure and a severe increase in jugular pressure. Head edema caused by the jugular vein occlusion in the horses could interfere with the autonomic cardiovascular regulation of arterial blood pressure during exercise, likely leading to an impairment of tissue perfusion. Jugular occlusion, even unilateral, also causes severe head venous congestion, leading to venous hypertension that was aggravated by exercise, which could risk development of cerebral edema and neurological damage. The present results obtained from sedentary horses are preliminary data that lead us to suggest that sport horses presenting jugular occlusive thrombophlebitis, even unilateral, may be prevented from performing athletic activities. © 2013 Elsevier Inc.

Is peripheral blood cell balanced altered by the use of fresh frozen bone block allografts in lateral maxillary ridge augmentation?

Background: The relationship between the immune response and red and white blood cell homeostasis is cited in literature, but no studies regarding the balance of these cell populations following maxillary bone-graft surgeries can be found. Aim: The aim of this study was to evaluate the possible impairments in the blood cell balance following fresh-frozen allogeneic bone-graft augmentation procedures in patients who needed maxillary reconstruction prior to implants. Material and Methods: From 33 patients elected to onlay bone grafting procedures, 20 were treated with fresh-frozen bone allografts and 13 with autologous bone grafts. Five blood samples were collected from each patient in a 6-month period (baseline: 14, 30, 90, and 180 days postsurgery), and the hematological parameters (erythrogram, leukogram, and platelets count) were accessed. Results: All evaluated parameters were within the reference values accepted as normal, and significant differences were found for the eosinophils count when comparing the treatments (30 days, p=.035) and when comparing different periods of evaluation (allograft-treated group, baseline×180 days, p≤.05 and 90×180 days, p≤.01; autograft-treated group, 30×90 days, p≤.05 and 30×180 days, p≤.05). Conclusions: Both autologous and fresh-frozen allogeneic bone grafts did not cause any impairment in the red and white blood cell balance, based on quantitative hemogram analysis, in patients subjected to maxillary reconstruction. © 2011 Wiley Periodicals, Inc.

Estudo da utilização do balanced scorecard na gestão da qualidade e excelência operacional aplicadas a projetos de engenharia em sistemas de potência

The expansion of the electrical system is currently a subject of great importance to the development of Brazil. For its realization, large projects are needed, requiring large-scale investment and realization processes of great complexity. Thus, this type of project has a high strategic importance for the performance of companies that conduct. Seeking a way to determine a method to align traditional practices for measuring quality to the corporate strategic needs, this work is the study of the use of the balanced scorecard methodology, applying quality management and operational excellence, with a focus on projects in power systems. We analyzed some cases of successful application of the methodology in business segments in the next study, culminating in a proposed model of the method

Análise da implementação do balanced scorecard em uma fornecedora de tecnologia da informação

Many companies have invested substantial resources in recent years in implementing the Balanced Scorecard, a strategic management tool that embraces not only financial perspectives, but also three other perspectives that create an overall and long-term vision of the company. The purpose of this article is to analyze, through interviews and action research, the implementation of the Balanced Scorecard in a provider of information technology and suitability for the company area Alliances and Channels, identifying determinants factors that exist in the literature and contributing to a greater understanding around this strategic management tool. The study shows that the implementation of the company was not successful, but the area of Alliances and Channels suit tool in order to find good results and two new determinants, other than those existing in the literature, were found

Facial type measurements influence on transverse dimensions of normal occlusion arches

Objective – To correlate facial type measurements of Caucasian individuals with transverse dimensions of normal occlusion arches. Methods – Twenty-one pairs of dental models were selected according to the following inclusion criteria: presence of all permanent teeth from 1 st molar to 1 st molar; normal occlusion; no prosthetic crowns; no previous orthodontic treatment and 2 mm or less of crow- dings or spacings. The cephalometric measurements of lateral cephalometric X-ray of the same individuals were taken and tabulat ed. To evaluate the repetition of arch measurements, paired Student’s t-test and Pearson's correlation coefficient were used. The r elationship between the measurements was analysed by using the Pearson’s correlation. Results – The repetition of the measurements showed high correlation and no systematic error. In the comparison between the measurements, a moderate negative correlation was observed b et- ween facial axis angle and the measurements Upper and Lower 6-6, whereas a positive correlation was observed between dentition height and the latter. Conclusion – It was observed a negative correlation between facial axis angle and upper and lower inter-molar distance as well as a positive correlation between dentition height and upper and lower inter-molar distance.

Modificação de forma e dimensões dos arcos superior e inferior obtidas em modelos de estudo após expansão rápida da maxila com o aparelho hyrax

The aim of an orthodontic treatment is the achievement of a balanced, esthetic and, most of all, stable, intra and inter arches relationship. A common problem observed in occlusion is posterior crossbite and atresic maxilla. This problem may be treated by slow expansion, rapid expansion or surgically assisted expansion. For the present study cast models of 14 children between 7 and 11 years old were evaluated. There were 7 male and 7 female subjects that presented posterior crossbite and needed rapid maxillary expansion. The Hyrax appliance performed the therapy for correction of this transversal alteration, which is a common possibility in the treatment of this malocclusion. It was observed that the distance between the upper first molars and upper cuspids increased significantly; the length of the upper arch decreased and its perimeter increased significantly. At the lower arch there were no dimensional changes.
