Association between sleep quality and quality of life in nursing professionals working rotating shifts

Objective: To analyze the association between sleep quality and quality of life of nursing professionals according to their work schedules. Methods: A prospective, cross-sectional, observational study was conducted between January and December 2010, with 264 nursing professionals, drawn from 989 subjects at Botucatu General Hospital and stratified by professional category. The Pittsburg Sleep Quality Index and the WHOQOL-bref were administered to evaluate sleep quality and quality of life, respectively. Self-reported demographic data were collected with a standard form. Continuous variables were reported as means and standard deviations, and categorical variables were expressed as proportions. Associations were evaluated using Spearman's correlation coefficient. The association of night-shift work and gender with sleep disturbance was evaluated by logistic regression analysis using a model adjusted for age and considering sleep disturbance the dependent variable. The level of significance was p < 0.05. Results: Night-shift work was associated with severe worsening of at least one component of sleep quality in the model adjusted for age (OR = 1.91; 95% CI 1.04; 3.50; p = 0.036). Female gender was associated with sleep disturbance (OR = 3.40; 95% CI 1.37; 8.40; p = 0.008). Quality of life and quality of sleep were closely correlated (R = -0.56; p < 0.001). Conclusions: Characteristics of the nursing profession affect sleep quality and quality of life, and these two variables are associated.

Epithelial-mesenchymal transition occurs in preneoplastic and neoplastic lesions of canine prostate

Background: The epithelial-mesenchymal transition (EMT) is an essential process in the tumor progression and metastasis. In human prostate carcinoma (PCa), the upregulation of cytokeratin and E-cadherin and down-regulation of vimentin have been associated with aggressive phenotype and poor prognosis. Due to the importance of canine cancer model it was evaluated the immunoexpression of AE1/AE3, E-cadherin and vimentin in canine prostatic lesions. Patients and Methods: A total of 75 prostatic tissues formalin-fixed paraffin embedded from dogs was selected: 10 normal prostatic tissues, 20 benign prostatic hyperplasia (BPH), 25 proliferative inflammatory atrophy (PIA) and 20 PCa. AE1/AE3 was detected with a monoclonal antibody (Invitrogen, 180132) at a 1:300 dilution, applied for 45 min at room temperature (RT). The antibody against Vimentin (V9, Invitrogen) and E-cadherin (NCH-38, Dako cytomatiomn) were monoclonal mouse antibodies, used at a 1:300 and 1:200, respectively, for 45 min at RT. The immunolabelling was performed by a polymer method (Histofine, Nichirei Biosciences,). A negative control was performed for all antibodies by omitting the primary antibody and substituting with Tris-buffered saline. The percentage of C-MYC, E-cadherin, and p63- positive cells per lesion was evaluated according to Prowatke et al. (2007). The samples were scored separately according to staining intensity and graded semi-quantitatively as negative, weakly positive, moderately positive, and strongly positive. The score was done in one 400 magnification field, considering only the lesion, since this was done in a TMA core of 1 mm. For statistical analyses, the immunostaining classifications were reduced to two categories: negative and positive. The negative category included negative and weakly positive staining. Chi-square or Fisher exact test was used to determine the association between the categorical variables. Results: All prostatic normal and BPH tissue were positive for cytokeratin, E-cadherin and negative for vimentin. Similarly, all PIA samples were positive for AE1/AE3. From those samples, 48% (12/25) were also positive for vimentin. 55% of PCa (11/25) was positive for vimentin and among these samples 75% (6/11) was also positive for AE1/AE3 and 45% (5/11) was negative for AE1/AE3. PIA and PCa presented a higher number of vimentin positive cells when compared with normal tissue (p=0.032). E-cadherin expression had no statistical difference among diagnosis groups, but we found a higher number of positive cases, with more than 51% of positive immunostaining in BPH and PIA (81.25% and 78.60% of the cases, respectively) than in PCa (55.55%). Conclusion: The carcinogenesis process regarding prostatic epithelial cells in dogs showed higher vimentin protein expression associated with concomitant loss of the cytokeratin and E-cadherin, similar in humans.

Increased cyclooxygenase-2 and vascular endothelial growth factor protein expression is associated with canine prostatic carcionogenesis process

Background: COX-2 is one of the most important prostaglandin involved in urologic cancer and seems to be associated with tumor progression, invasion, and metastasis. In addition, several effects have been reported for VEGF, including inducing angiogenesis, promoting cell migration, and inhibiting apoptosis. COX2 and VEGF up-regulation have been reported in human prostate cancer. Due to the importance of canine natural model for prostate cancer, the aim of this study was to evaluate COX-2 and VEGF protein expression in canine carcinogenic process. Material and Methods: Seventy-four prostatic tissues from dogs were selected to be evaluated for protein expression by immunohistochemistry (IHC), including: 10 normal prostatic tissues, 20 benign prostatic hyperplasias (BPH), 25 proliferative inflammatory atrophies (PIA) and 20 prostatic carcinomas (PCa). COX-2 and VEGF were detected using the monoclonal antibody CX-294 (1:50 dilution, Dako Cytomation and sc-53463 (1:100 dilution, Santa Cruz), respectively. The immunolabelling was performed by a polymer method (Histofine, Nichirei Biosciences). All reaction included negative controls by omitting the primary antibody. The percentage of C-MYC, E-cadherin, and p63- positive cells per lesion was evaluated according to Prowatke et al. (2007). The samples were scored separately according to staining intensity and graded semi-quantitatively as negative, weakly positive (1), moderately positive, and strongly positive. The score was done in one 400 magnification field, considering only the lesion, since this was done in a TMA core of 1 mm. For statistical analyses, the immunostaining classifications were reduced to two categories: negative and positive. The negative category included negative and weakly positive staining. Chi-square or Fisher exact test was used to determine the association between the categorical variables. Results: The COX-2 protein expression was elevated in the cytoplasm of the canine PCa and PIA compared to normal prostate (p=0.002). VEGF protein expression was increased in 94.75% of the PCa and 100% of the PIA compared with to normal prostate (p = 0.001). No difference was found when compared normal prostate with BPH. Conclusions: This study has demonstrated that the carcinogenesis of canine prostatic tissue may be related to gain of COX-2 and VEGF protein expression.

Actitud de los docentes de las facultades de Odontologia Brasilenas ante los aspectos bioeticos, eticos y legales del tratamiento odontológico

The study consist on an analysis of attitude by professors of Brazilian Dental Schools before the aspects bioethical, ethic and legal dental treatment aspects. The data collect occurred by semi-structured questioners send by e-mail and correspondence. It was applied the content analysis, by categorical analysis technique, according to Bardin. About bioethical aspects, 94,6% cited that the decision of treatment should be realized between professional and patient, because it don t interfere on negative form (100%). Everybody consider important the interaction professional/patient, because it establishes the respect and mutual agreement between them (61,8%). Tangent at ethic aspects, 95,5% show all alternatives for determined case, even knowing that can lost patient, explaining on the technique and laical form to clear doubts(61,9%). About legal aspects, 82,4% allege that dental surgeon should treat his patient like consumer whereas offer techniques, materials and know through profession. And, like legal prove on occasional lawsuit, 57,1% mentioned that professional don t need of contract necessarily, but a good documentation about patient and e assigned by him. It concluded that these aspects should be teached always to Dentistry academics, whereas they re inherent at profession, to not stay vulnerable at future ethic, judges and other problems.

Potencial de ocorrência de avarias ambientais em bacias hidrográficas com ocupação rural mediante análise morfométrica

The understanding of the geo-morphological characteristics allows the identification of flood areas and instability slopes among others important features for land use planning. The study of the hydrological net and the analysis of morphometric parameters help in the geomorphologic characterization, providing specific physics indicators that quantify the risks for environmental damages. The present work used Geographic Information Systems (GIS) and carried out the morphometric analysis of two watersheds in the Alto Rio Sorocaba, municipality of Ibiuna (SP). Using digitalized topographic bases in the scale 1:50,000, the main morphometric parameters were extracted and the Digital Elevation Model (DEM) was obtained. Hence the slope, ground illumination, hill orientation and relief feature maps were elaborated. The characteristics for the two watersheds were quite similar, both have low risks for floods and landslides. Therefore, the concave feature is the predominant hill shape for both watersheds. The morphometric parameters directly related to the river density of the watersheds showed some differences, because the Sorocabuçú watershed presents higher value, resulting in a higher level of relief development. Thus, with this characterization it is possible to provide subsidies for environmental planning actions to the area.

Professores de arquitetura diante da questão do desenvolvimento humano e da inclusão social das pessoas com deficiência

Professors of Architecture on the Subject of Human Development and Social Inclusion of People With Disabilities Historical-Cultural Psychology believes that the people appropriate the culture and develop themselves by social interactions. The architect acts indirectly on human development by producing spaces that allow varying levels of interaction between individuals. To know if the Brazilian Architecture courses are graduating professionals who facilitate the social inclusion of people with disabilities, this research aimed to investigate the concepts of Architecture teachers of a public university about this theme. After the interviews, the reports obtained were submitted to the categorical-content analysis method. Technical concepts predominated over reflective ones, except for the architecture concept, classified as a knowledge area which brings gains to human life.
