Background: The aim of the present study was to assess the level of satisfaction of dentists working in primary healthcare (PHC) with a Distance learning (DL) course in pediatric dentistry offered by the TeleHealthRS center, and to the investigate possible associations between the variables indicative of their satisfaction and their performance on the questionnaires applied before and after the course. Methods: The course was offered in 2015 by the Federal University of Rio Grande do Sul (UFRGS) together with the TeleHealthRS center in Brazil. Data were collected on the participants’ personal and professional profile, their pre- and post-course knowledge about pediatric dentistry, and their satisfaction with the course. Student's t-test and the ANOVA test were used to assess the possible associations between the variables indicative of their satisfaction and their performance on the questionnaires applied before and after the course. Results: Overall, the participants were satisfied with the course, however, no statistically significant association was found between the variables indicative of their satisfaction and the grades they earned on the pre- and postcourse questionnaires. Conclusion: The available pediatric dentistry course received positive evaluations from the participants, constituting a possible strategy for the qualification of primary care dentists. Future studies are warranted to further investigate the expectations of DL course participants, aiming to enhance the quality of future editions of this learning modality for pediatric dentistry contents.

This study aims to explore the association between nurses' leadership styles and personal and professional nursing profile and workload. The sample consisted of seven nurses and seven nursing technicians who were grouped into pairs. At the end of three months, nurses were queried regarding what leadership style would be adopted when the nursing technician under their evaluation delivered care to patients admitted to the ICU. Relevant data was analyzed by applying descriptive statistics, Tukey's multiple comparison test and Student's t-test (p< 0.05). Nursing workload reached 80.1% on average. The personal and professional profile variables did not show any relation with the leadership styles chosen by nurses (p>0.05). The determine, persuade, and share leadership styles prevailed. However, whenever the nursing workload peaked, the determine and persuade styles were used (p<0.05).

Background: Primary menstrual pain affects approximately 45-95% of women between 20-25 years of age. A non-invasive method in reducing menstrual pain by relaxing muscle tension is a massage. It brings the structural tension to normal levels and restores correct blood flow in the pelvic region. Aim of the study: The aim of this study was to test the usefulness of a self-massage in reducing the primary menstrual pain. Materials and methods: Out of 180 female students, 34 women aged 19-30 were qualified for the study with the use of a survey. Pittsburgh Sleep Quality Index questionnaire and visual analog pain scale (VAS) were used for the assessment before and after the therapy. Women in the experimental group performed tensegrity selfmassage a few days before the onset of bleeding for two menstrual cycles. Results were analyzed using Student’s t test and one-way analysis of variance (ANOVA). Results: Applying the self-massage statistically proved to significantly reduce the perception of pain (p=0.001) and the number of days with pain (p=0.007) in the experimental group. Within this group, the difference was noted in all participants except one. In addition, a third measurement was taken in order to assess the duration of the effect. The result of the average pain and number of days of pain after the extension was higher than in the second evaluation, but significantly lower than before the experiment. The significance was in accordance with the evaluation of pain, p=0.002 and number of days p=0.03. Evaluation of the quality of sleep in the experimental group was significantly better (p = 0.04) than before treatment. Conclusions: Self-massage reduces primary menstrual pain in women and can be used as an assisted form of self-therapy. It improves the quality of sleep.

Emotional intelligence is the sum of a person's skills and abilities to recognize emotions, to understand the intentions, motivations and desires of other people and their own, as well as the ability to manage their emotions and the emotions of other people in order to solve practical problems. The purpose of the study is to develop and test a methodology for the development of emotional intelligence as a fundamental quality of leadership formation in conjunction with managerial competencies. The study involved 576 students. The following complex of methods was used in the work: theoretical analysis and generalization of scientific and special literature data; conceptual-terminological and systemic-structural analysis; testing: a questionnaire of general empathic tendencies; communicative tolerance; tolerance test; test for assertion; diagnostics of self-esteem and level of aspirations; factorial personality questionnaire by R. Cattell; diagnostics of emotional intelligence N. Hall; pedagogical experiment; analysis and generalization of the results of experimental studies; methods of mathematical statistics. Summing up the results of our research, it should be noted that all thirteen studied parameters showed positive dynamics of their development. Eight of them have significant differences in the results before and after the experiment according to the Student's t-criterion (P ? 0.01): empathy, tolerance, tact, the significance of empathy, the significance of tolerance, the significance of tact, the level of self-esteem and aspirations. It is important to note that for three of them: the significance of empathy, the level of self-esteem and aspirations - the reliability according to the Student's t-criterion is P ? 0.05. Upon completion, N. Hall's emotional intelligence was diagnosed. Of the 70.14% of students with a low level of development of emotional intelligence, at the end of the formative experiment, only 5.90% remained in this group. The proposed methodology includes structural diagnostics of the level of development of emotional intelligence, generalization of the results in order to identify problem areas and the development of recommendations that contribute to the development of emotional intelligence.

The shear-stress sensor function of vascular glycocalyx heparan sulphate and hyaluronic acid was investigated in vivo by assessing flow-mediated dilation before and after their removal. Heparinase III exposure (100 mU·mL−1 for 20 min;n = 6) did not significantly affect flow-mediated dilation of the iliac, from 0.42 ± 0.08 mm (mean ± SEM) to 0.34 ± 0.07 mm after (P = 0.12; paired Student’s t test) for a statistically similar increase in shear stress; 18.24 ± 4.2 N·m−2 for the control and 15.8 ± 3.6 N·m−2 for the heparinase III experiment (P = 0.18). Hyaluronidase exposure (0.14–1.4 mg·mL−1 for 20 min; n = 8) also did not significantly reduce flow-mediated dilation of the iliac, which averaged 0.39 ± 0.08 mm before and 0.38 ± 0.09 mm after (P = 0.11) for a statistically similar increase in shear stress; 11.90 ± 3.20 N·m−2 for the control and 9.8 ± 3.33 N·m−2 for the hyaluronidase experiment (P = 0.88). Removal of both heparan sulphate and hyaluronic acid was confirmed using immunohistochemistry. Neither the heparan sulphate nor the hyaluronic acid components of the glycocalyx mediate shear-stress-induced vasodilation in conduit arteries in vivo.

ABSTRACT The objective of this work was to assess the effect of vegetation on the runoff coefficients of a Caatinga dry tropical forest before and after thinning. Thus, an experiment was conducted with evaluations in three hydrological years (2008, 2011 and 2013) in Iguatu, State of Ceará, Brazil. In 2008, the vegetation consisted of a 30-year regenerating Caatinga forest. The vegetation was subjected to thinning in 2009, 2011 and 2013, removing trees with less than 10-cm diameter at breast height. Hydrological responses were evaluated as a function of daily precipitation water depths, based on cumulative frequency distribution, by dividing precipitation events into three classes (CP) (CP≤30, 30<CP≤50 and CP>50 mm). Significant differences between runoff coefficients before and after vegetation thinning were assessed through the Student's t-test (p<0.01). Before thinning (2008), CP≤30 mm showed the highest runoff coefficient, differing statistically (p<0.01) from the other years. The results of precipitation events of great magnitude (CP>50 mm) indicate that the runoff is greatly dependent on rainfall characteristics and soil moisture conditions. The greater development of herbaceous vegetation due to thinning reduced the surface runoff.

ABSTRACT Context: Presurgical nasoalveolar moulding (PNAM) is a non-surgical method of reshaping the cleft lip, alveolus, palate and the nose to minimize the severity of the cleft deformity, before primary cheiloplastyand palatoplasty. In this context, PNAM proves to be an invaluable asset in the management of unilateral cleft lip and palate. Aims: The study was conducted to evaluate the effi cacy of PNAM in the management of unilateral cleft lip and palate with the following objectives: (1) To assess and compare the degree of reduction in the size of cleft palate and alveolus (pre-PNAM and post-PNAM). (2) To evaluate and compare the improvement in columellar length and correction of columellar deviation (pre-PNAM and post-PNAM). (3) To assess the changes in the position of the alar base and the alar cartilages. Settings and Design: Prospective study. Subjects and Methods: A prospective study consisting of, which included 20 patients with complete unilateral cleft lip and palate was conducted. The age at the start of PNAM treatment of the infants ranged from 2 to 44 days of age reporting to our institute between December 2011 and August 2013. All the patients underwent PNAM therapy before primary cheiloplasty at 6 months of age; clinical parameters were assessed pre- and post-therapy using photographs and dental study models of the maxilla. Statistical Analysis Used: Student's t-test for paired comparisons. Results: Results of the study showed a promising reduction in the cleft size before the surgery, signifi cant improvement in nasal symmetry, including the columellar length on the cleft side. Conclusions: PNAM is a valuable adjunct to our surgical armamentarium in dealing with the challenges of primary closure of unilateral cleft lip and palate thereby enhancing the overall surgical outcome. The advantages of this method include the simplicity of the procedure and improving the quality of surgical repair, particularly in obtaining tension free muscle closure in unilateral clefts.

Formation of student youth’s social activity is the leading task of social education, especially under conditions of information society. If psychological and age traits of students as a social group are to be taken into account, the beneficial means of harmonizing this process is leisure activities. Based on interdisciplinary and integrated approaches, a system of social-pedagogical leisure activities was developed to form social activity of student youth. The aim of this article is to analyze the implementation of the social-pedagogical leisure activities system of student youth’s social activity formation. The task of this article is to study the levels of student youth’s social activity before and after implementing the social-pedagogical leisure activities system and to analyze its effectiveness using the corresponding methods. According to outlined tasks, the following methods and indices were selected and used: relative indices method, grouping method, quantitative and qualitative analysis method, Student’s t-test, graphical method. Thanks to systematic approach to experimental part of the research, it was established that the level of students’ social activity formation has improved: the specific share of young people with low level has decreased significantly, while of those with high level has increased. Group curators have noted the tendencies of young people to organize leisure activities, while students themselves were becoming involved in useful leisure practices that were new to them. Effectiveness of the new system was confirmed using statistical methods.

Abstract Background: Atopic dermatitis (AD) is a chronic inflammatory skin disease that is known to cause a significant adverse impact on the quality of life of patients. Reducing chronic itch that has a complex mechanism is one of the most important challenges in AD treatment.Objective: To evaluate the effect of a temperature-adjustable cryotherapy device on mice with lysophosphatidic acid-induced pruritus.Methods: A temperature and time-adjustable cryotherapy device was used for the treatment of lysophosphatidic acid-induced pruritus of mice in the following conditions: −5℃, 0℃, or 5℃ for 5 sec, 10 sec, or 20 sec. Expression of itch-related biomarkers before and after modulation of temperature was investigated with real-time polymerase chain reaction (PCR) and immunohistochemistry.Results: Expression of itch-related biomarkers was decreased after modulation of temperature. For gene expression, all were decreased at 5℃ for 10 sec and 20 sec, and at 0℃ for 5 sec, 10 sec, and 20 sec. For protein expression, all were decreased at 5℃ for 10 sec and 20 sec, and at 0℃ for 5 sec and 10 sec.Conclusion: This study demonstrates the pruritus-relieving effect of the temperature-adjustable device on mice. This may provide some evidence for future studies on patients with mild AD.

Metallic objects, such as intracanal posts and restorations, may produce severe interference, thus diminishing the quality of CBCT imaging. Objective: The purpose of this study was to analyze the influence of conventional and bioceramic gutta-percha points on the production of artifacts in CBCT images. Methods: Extracted single- -rooted premolar teeth (n=20) were instrumented and scanned with a CBCT device to create three groups: the Control group, the Gutta-Percha group and the Bioceramic Gutta-Percha group. Two types of analysis were executed: an objective one, using the Region of Interest (ROI) to measure the pixel density of each tooth, and a subjective one, to compare the groups’ images. For the statistical analysis, Student’s t-test, descriptive statistics and the frequency distribution analysis were used for both objective and subjective analyses. Results: The agreement between the observers ranged from moderate to excellent. Similar grayscale values were obtained in both the GP and BCGP groups. These results were endorsed by the p-values obtained with Student’s t test. For the subjective analysis, the observers indicated the BCGP group as the one that developed the highest number of artifacts. Conclusions: Both materials produced artifacts in the CBCT images. However, in the subjective analysis, the BCGP group showed higher levels of artifact production than the GP group, which could result in the misdiagnosis of root fracture and in a worse prognosis for that tooth.
