New Technologies of Information / Communication offer the option of using a virtual learning environment (VLE), which allows for greater interactivity in daily nursing education urging educators to rethink their teaching practices. The aim of this study was to report the experience of the use of virtual environment in nursing education from the perspective of students. The discipline "Nursing Education: Trends and Challenges" was given to 78 students from the 4th semester of undergraduate nursing, from which 48 answered a questionnaire with closed and, among these, 33 answered an open question about the use of AVA. Students considered the AVA a facilitating tool of learning, the process of knowledge construction and interaction between students, teachers and tutors enriching thus the sharing of ideas and allowing a meaningful and collaborative learning. The study revealed the need for enhancement of use of VLE in teaching undergraduate nursing.
Introduction: Marginal discrepancies may lead to cement washout and marginal leakage, damaging periodontal and pulp tissues or causing premature loss of the restoration. Purpose: This study evaluated the influence of application site of provisional cement on the marginal adaptation of provisional crowns. Material and Methods: Four different application sites of provisional cement (Temp Bond NE, Kerr Corporation) were used for cementation of provisional crowns on phantom teeth prepared for full crown restorations, performing 4 experimental groups (n=10): cement applied to all internal surfaces of the crown (CAO); cement applied to all internal surfaces of the crown, except for the occlusal surface (CA); cement applied to the cervical crown margin (CM); and cement applied to the cervical tooth margin (TM). A comparison microscope (Mitutoyo America Corporation) was used to measure the distances between the internal tangents of two circular marks, one made on the provisional crown and one made apical to the tooth preparation margin, in areas corresponding to buccal, lingual, mesial and distal surfaces. Marginal adaptation was determined before and after cementation, with 0.0001-mm accuracy. Data were analyzed statistically by ANOVA and Tukey's test at 5% significance level. Results: Mean values of marginal opening obtained for each group were: CAO: 145 μm; CA: 67 μm; CM: 46 μm; TM: 34 μm. CA, CM and TM presented significantly lower marginal openings than CAO (p<0.05). Conclusion: complete filling of the crown with provisional cement, including the occlusal surface, provided grater marginal discrepancies when compared to the other methods evaluated.

any temporary cements are commercially available; therefore, it is necessary to indicate them for each clinical requirement with regard to the tensile strength of prosthetic retainers. Thus, the purpose of this study was to compare the retention of provisional crowns cemented with eight temporary cements, over full crown preparations with standardized mechanical principles as height, taper, and length. For that purpose, eighty human first premolars received full crown preparation with standardized height and taper. Provisional crowns were fabricated and luted with eight brands of temporary cements. Twenty four hours after cementation, the restorations were submitted to tensile strength test in a universal testing machine and the data submitted to ANOVA and Bonferroni tests. Mean tensile strength values ranged from 20.1N for Nogenol cement to 67.5N for Hydro C cement. Statistically significant difference (p<0.05) was found between Hydro C and the other groups, except for Temp Bond and Rely X Temp, which presented statistically significant difference when compared to Freegenol and Nogenol temporary cements. The crowns cemented with Hydro C cement were more retentive that than those cemented with the other cements, except for Rely X Temp and Temp Bond. The less retentive crowns were those cemented with Nogenol and Freegenol temporary cements. Uniterms: Temporary cements; Tensile strength; Tooth crown preparation. uitas marcas de cimentos temporários estão disponíveis no mercado odontológico, sendo necessário adequá-los a cada necessidade clínica no que diz respeito à resistência à remoção dos retentores protéticos. Assim, o objetivo desse estudo foi avaliar a retenção de coroas provisórias cimentadas com oito cimentos temporários sobre preparos para coroa total com princípios mecânicos padrozinados como altura, conicidade e extensão. Para isso, oitenta primeiros pré-molares humanos receberam preparos para coroa total com altura e conicidade padronizadas. Coroas provisórias foram confeccionadas e cimentadas com oito marcas de cimentos temporários. Vinte e quatro horas após a cimentação, as restaurações foram tracionadas em uma máquina universal de ensaios e os dados submetidos aos testes estatísticos de ANOVA e Bonferroni. Os valores médios de resistência à tração variaram de 20,1 para o Nogenol a 67,5 para o Hydro C. Diferença estatisticamente significante (p<0.05) foi encontrada entre o cimento Hydro C e os outros grupos, com exceção do Rely X Temp e do Temp Bond, que apresentaram diferença estatisticamente significante quando comparados aos cimentos Freegenol e Nogenol. As coroas cimentadas com Hydro C foram mais retentivas do que aquelas cimentadas com os outros cimentos com exceção do Rely X Temp e do Temp Bond. As coroas menos retentivas foram aquelas cimentadas com os cimentos Nogenol e Freegenol.

Introduction: Urinary tract infections in the community setting are quite common. It is necessary to be aware of antibiotic susceptibility patterns in order to provide rational empirical therapy. The aim of this study is to determine the frequency and antimicrobial susceptibility of the strains responsible for urinary tract infections in primary health care, in the district of Coimbra, Portugal.Material and Methods: In this observational and cross-sectional study, we analyzed 7134 positive urine cultures of outpatient laboratories in the district of Coimbra, over one year. In most cases, a positive culture was defined by a threshold of 105 colony-forming units per milliliter and was conducted by the automated system VITEK® 2, by bioMérieux. We used descriptive and inferential statistics to determine the prevalence and antimicrobial susceptibility of bacteria and to ascertain whether there were differences associated with sex and age.Results: From the total of positive cultures, 83.4% pertained to females and 41.0% to individuals over 75 years old. Escherichia coli was the most frequent strain (63.9%), although its prevalence was lower (p < 0.001) in males and individuals over 75 years old. Its susceptibility to fosfomycin and nitrofurantoin was higher than 95% and with ciprofloxacin and trimethoprim/sulfamethoxazole it was lower than 80%. Resistances were more frequent (p < 0.001) in males and in the elderly.Discussion: Escherichia coli was the most frequent strain, revealing less resistance to fosfomycin and nitrofurantoin. Antimicrobial susceptibility was lower in the elderly and in males, populations in whom empirical therapy may be less successful.Conclusion: In order to improve clinical results, we recommend periodic surveillance of antimicrobial susceptibility, which could enable the provision of efficient information to clinicians, namely those who prescribe empirically for such infections, as well as standardization of identification methods of bacterial strains diagnosis and of the antibiotic kits to be tested.
