Aims: To identify the strategies for the prevention of burnout syndrome in nurses; and discuss the results for future interventions that can decrease burnout in these professionals. Design: An integrative review of the literature. Data Sources: PubMed, Lilacs, Medline, Scielo, and Science Direct, from April 2018 to July 2018. Methods: The sources were in all 553 references were found. The following guiding question was: Which interventions for the prevention of burnout in nurses have been applied and have obtained high effectiveness? Results: Based on the inclusion and exclusion factors, 30 studies were selected for analysis. The studies were categorized in individual, group and organizational, being the studies with actions in groups those of greater prevalence. Conclusion: The actions used to cope with burnout were, for the most part, effective, with some demonstrating greater success than others. From the 30 reviewed studies, the results did not obtain satisfactory improvement in burnout in only three interventions: 1) Systematic nursing supervision; 2) Basic nursing care; and 3) Psycho-oncological training program.

Background: The quality of life (QoL) of patients with endometriosis and infertility was assessed in different stages and correlated with the clinical features of the cases. Methods: The present study was a cross-sectional study; 106 women were included, divided in two endometriosis groups (Grade I/II, 26 women, and Grade II/IV, 74 women). All participants attended the Endometriosis and Infertility Outpatient Clinic of the Instituto Ideia Fértil de Saúde Reprodutiva, Faculdade de Medicina do ABC, São Paulo, Brazil, were and responded to the Short Form (SF) Health Survey-36. Convenience sampling was used due to the authors’ access to the study population; however, the sample number was calculated to be sufficient for 95% power in both groups. Results: Homogeneity was observed between Grade I/II and Grade III/IV staging, with similar mean ages (35.27, ±3.64 years and 34.04, ±3.39 years, respectively, p = 0.133); types of infertility (p = 0.535); infertility time (p = 0.654); degrees of pain (p = 0.849); and symptoms common to endometriosis, namely, dysmenorrhea (p = 0.841), dyspareunia (0.466), chronic pelvic pain (p = 0.295), and intestinal (p = 0.573) or urinary (p = 0.809) diseases. Comparisons of median scores in the QoL domains demonstrated that the distributions of QoL and clinical symptoms were significantly related between the types of dyspareunia and the following domains: physical functioning (p = 0.017), role- emotional (p = 0.013), and general health (p = 0.001). Regarding pain outside of menstruation, there was significance in the pain domain (p = 0.017), and degree of pain was significance in physical functioning (p = 0.005) and role-physical (p = 0.011) domains. Conclusions: The present study pointed out that it is not the stage of endometriosis that interferes in the quality of life of women with endometriosis and infertility but rather the clinical manifestations, such as dyspareunia and pain. Thus, we can conclude that the patient’s perception of the disease should be considered in health care and that the losses are independent of the degree of endometriosis in this population with the aggravating factor of infertility.

Background: Patients with breast cancer—the deadliest cancer among women—are at constant risk of developing metastasis. Oxidative stress and hypoxia are common feature of tumor cells that can proliferate even in a resultant metabolic acidosis. Despite the low extracellular pH, intracellular pH of tumor cells remains relatively normal, or even more alkaline due to the action of a membrane protein family known as monocarboxylate transporters (MCTs). The objective of this study was to verify the diagnostic and prognostic value of MCT1, MCT4 and CD147 in tumor and peripheral blood samples of patients with breast cancer undergoing chemotherapic treatment. Methods: Differential expression of MCT1, MCT4 and CD147 obtained by qPCR was determined by 2−ΔΔCq method between biological samples (tumor and serial samples of peripheral) of patients (n = 125) and healthy women (n = 25). Results: tumor samples with higher histological grades have shown higher expression of these markers; this higher expression was also observed in blood samples obtained at diagnosis of patients when compared to healthy women and in patients with positive progression of the disease (metastasis development). Conclusion: markers studied here could be a promising strategy in routine laboratory evaluations as breast cancer diagnosis and prognosis.

Background: Access to the diagnosis and treatment of breast cancer in Brazil is marked by immense inequalities in the provision of specialized assistance, which leads patients to seek treatment outside the place of residence. To evaluate the variations between 2004 and 2014 in the distribution of flow between place of residence and care, and the average distance traveled for treatment of breast cancer in the administrative regions and federal states of Brazil. Method: Analysis of secondary data from the years 2004 and 2014, extracted from the Department of Informatics of the Unified Health System through the Hospital Information System. Data from Hospitalization Release Authorizations were collected, and the maps were created with TabWin 3.6 software. Descriptive analysis was performed on Stata® (StataCorp, LC) 11.0. Results: In the total flow, it was observed that there was a decrease in referrals between 2004 and 2014 in most regions. In 2004 the main direction of flow was in the Midwest and Southeast regions. In 2014, however, the intensity of these admissions was centralized in the Southeast region. In relation to the average distance traveled, the North, Northeast, and Midwest regions had the highest values of displacement. Of the 27 federative units, 17 presented an increase in average distance between these periods. Conclusion: Despite the improvement in the hospitalization of residents, in most regions and federal units, Brazilians still travel great distances when they require treatment for breast cancer.

To analyze the correlation between municipal human development indices (MHDIs) and stroke mortality in residents of Brazilian state capitals in 2010. A secondary data analysis was conducted in 2015 using data for the MHDI and the following dimensions: income, longevity and education which were obtained from the United Nations Development Program. Additionally, we analyzed age-standardized stroke mortality data from the Department of System Information Unified Health of Brazil. We observed a correlation between stroke mortality and MHDIs overall (Pearson r = − 0.563; p = 0.002) and within the following dimensions: income (Spearman’s ρ = − 0.479; p = 0.011), longevity (Pearson r = − 0.510; p = 0.006) and education (Pearson r = − 0.592; p = 0.001). We identified moderate but significant negative correlations between MHDI overall and in its individual dimensions (income, longevity, and age) and stroke mortality in Brazilian capitals. Stroke is the second leading cause of death in industrialized countries and the leading cause of death in Brazil. Therefore, the discovery of factors that may influence the epidemiology of stroke is important for the construction of adequate policies considering to the socioeconomic status in these places and with an emphasis in lower socioeconomic status places.

Previous studies have described significant impact of different types of noise on the linear behavior of heart rate variability (HRV). However, there are few studies regarding the complexity of HRV during exposure to traffic noise. In this study, we evaluated the complexity of HRV during traffic noise exposure. We analyzed 31 healthy female students aged between 18 and 30 years. Volunteers remained at rest seated under spontaneous breathing during 10 minutes with an earphone turned off, and then they were exposed to traffic noise through an earphone for a period of 10 minutes. The traffic noise was recorded from a very busy city street and the sound was comprised of car, bus, and trucks engines and horn (71–104 dB). We observed no significant changes in the linear analysis of HRV. CFP3 (Cohen’sd= 1.28, large effect size) and CFP6 (Cohen’sd= 1.11, large effect size) parameters of chaotic global analysis and Shannon (Cohen’sd= 1.13, large effect size), Renyi (Cohen’sd= 1.06, large effect size), and Tsallis (Cohen’sd= 1.14, large effect size) entropies significantlyincreased(p< 0.005) during traffic noise exposure. In conclusion, traffic noise under laboratory conditions increased the complexity of HRV through chaotic global analysis and some measures of entropy in healthy females.
