OBJECTIVE This in vitro study evaluated the effect of commercial whitening dentifrices on erosive tooth wear (ETW) of bovine enamel samples, in comparison with commercial regular dentifrices. METHODOLOGY Sixty bovine crowns were embedded in acrylic resin, polished and then had their baseline profile determined. They were randomly assigned to 5 groups (n=12/group), according to the type of commercial dentifrice to be tested GI – Crest Anti-cavity Regular; GII – Crest 3D White; GIII – Colgate Total 12 Clean Mint; GIV – Colgate Optic White; GV – Placebo (negative control, fluoride-free dentifrice). The samples were submitted to daily erosive and abrasive challenges for 3 days. The erosive challenges were performed 3 times a day by immersing the specimens in 0.1% citric acid solution (pH 2.5) for 90 s. Each day after the first and last erosive challenges, the specimens were subjected to the abrasive challenge for 15 s, using a toothbrushing machine (Biopdi, São Carlos, SP, Brazil), soft toothbrushes and slurry (13 g/ml) of the tested toothpastes (1.5 N). The specimens were kept in artificial saliva between the challenges. The final profile was obtained and the ETW (µm) was calculated. Data were analyzed by Kruskal-Wallis and Dunn’s tests (p less then 0.05). RESULTS All dentifrices tested significantly reduced the enamel wear in comparison with the Placebo, except GIII. The median (95% CI) ETW was 1.35 (1.25-1.46)bc for GI, 1.17 (1.01-1.34)cd for GII, 1.36 (1.28-1.45)ab for GIII, 1.08 (1.04-1.14)d for GIV and 2.28 (2.18-2.39)a for GV. CONCLUSION When dentifrices from the same manufacturer were compared, the whitening dentifrices led to similar or less wear than the regular ones.OBJECTIVE To analyze the scientific literature produced on health education through mobile applications for surgical patients. METHOD An integrative literature review performed through consultation in the following portals and/or databases VHL; PubMed; Web of Science; Scopus; LILACS and CINAHL. The search was guided by the question „What is the evidence on the use of mobile applications in the health education of surgical patients?” conducted from July to September 2017, including articles published from the year 2000 to 2017. RESULTS Five articles published in international journals in English with varied methodological designs were selected. Among the studies found, 60% used an educational intervention through smartphone applications in the pre and postoperative periods, and 40% of the studies had an evidence level of 2B. CONCLUSION The studies showed that the use of smartphone applications in educating and guiding surgical patients was effective. However, there is still a gap in studies which demonstrate surgical patient education through smartphone applications.OBJECTIVE To analyze the characteristics and performance of the teams of the Expanded Family Health and Basic Healthcare Centers (Nasf-AB) of Santa Catarina state. METHOD A multicenter study implementing mixed methods, a sample of 149 municipalities (50.5% of the state) and 359 professionals through applying a survey and collective interviews with five teams of 43 professionals. Quantitative data were analyzed using descriptive statistics, and qualitative data were subjected to thematic analysis. RESULTS There were 11 professions integrated to the Centers with a predominance of psychologists (27%), physiotherapists (18%) and nutritionists (18%). The professionals were mostly women (88%) aged between 30 and 39 years (50.4%), with their performance involving shared care, collective activities of their professional core, group activities and individual care to users. Professionals participate in the intermediation, regulation or evaluation of referrals from Primary Care to other points of the Network. The interviews revealed a set of actions of technical care and technical-pedagogical support and specialized actions. CONCLUSION Despite operational difficulties, the Expanded Family Healthcare Centers have been supporting Family Healthcare teams, strengthening Primary Care.OBJECTIVE To perform criterion validation of the Key Question in Portuguese for screening at-risk alcohol use among users of Primary Healthcare services. METHOD This is a psychometric study conducted with users of a Primary Healthcare service located in the city of São Paulo, Brazil. Participants responded to the Key Question which was applied in conjunction with the Alcohol Use Disorders Identification Test-C for concurrent validation and measurement of psychometric properties. RESULTS The sample consisted of 518 users. The Key Question presented 59% specificity and 99% sensitivity with respect to the Alcohol Use Disorders Identification Test-C in the general population. The accuracy was 81% in relation to this instrument. There was no influence of sociodemographic variables such as gender on the psychometric properties of the Key Question. CONCLUSION The results indicate that the Key Question in Portuguese presented satisfactory psychometric qualities and suggest that its Portuguese version is as efficient for screening at-risk alcohol use as its reference standard, which subsidizes its use in Primary Healthcare.OBJECTIVE To characterize ethnographic research in the area of obstetric nursing regarding its theoretical, methodological and analytical aspects. METHOD An integrative review performed in the MEDLINE®, LILACS, BDENF and CINAHL databases, as well as the SciELO virtual library. RESULTS Thirty (30) articles formed the analytical corpus after screening and reading the primary references in full. The most used methods were ethno-nursing, ethnography and institutional ethnography; the immersion time in the field ranged from 12 visits to 48 months occurring in institutional contexts. The main data collection techniques were observation, individual interviews and training guides for ethno-nursing. The data were organized as themes and subthemes, analyzed through the ethno-nursing analysis guide, implementing the Theory of Diversity and Universality of Cultural Care as theoretical reference. CONCLUSION Ethnographic studies in the area of obstetric nursing are within the scope of microethnographies and are operationalized based on theoretical-methodological nursing references, being useful to analyze the complexity of phenomena involving obstetric nursing care, and focusing on the etic (professional) and emic (women) perspectives.OBJECTIVE To evaluate an educational program based on the principles of self-management with a conventional educational program through quality of life, anxiety and depression instruments within 12 months of starting cancer treatment. METHOD An experimental, randomized, controlled study conducted with head and neck cancer patients treated at a university hospital in the city of São Paulo, Brazil. Patients were randomly divided into two groups the control group submitted to the conventional educational plan, and the experimental group submitted to the educational plan for self-management. Descriptive and analytical statistics were used for the analyzes using the t-test, Fischer’s exact test and Repeated Measures ANOVA. RESULTS Twenty (20) patients were selected. Most participants were male, in advanced stages of disease and undergoing three therapeutic modalities. The control group showed a gradual decrease in quality of life scores during treatment, while the experimental group progressively increased. The correlation was significant between the presence of anxiety and depression symptoms and poor quality of life. Patients in the control group had a significant worsening in social/family well-being (P = 0.02) and the prevalence of additional head and neck cancer-related additional concerns (P = 0.01), while the experimental group had reduced anxiety symptoms (P = 0.001) and improved emotional well-being (P = 0.01). CONCLUSION The educational intervention based on building self-management skills favored quality of life and reduced anxiety and depression. Brazilian Registry of Clinical Trials (RBR 2q53ct).OBJECTIVE To generate reference values for spirometry in Brazilian children 3-12 years of age and to compare those values with the values employed in the equations currently in use in Brazil. METHODS This study involved healthy children, 3-12 years of age, recruited from 14 centers (primary data) and spirometry results from children with the same characteristics in six databases (secondary data). Reference equations by quantile regressions were generated after log transformation of the spirometric and anthropometric data. Skin color was classified as self-reported by the participants. To determine the suitability of the results obtained, they were compared with those predicted by the equations currently in use in Brazil. RESULTS We included 1,990 individuals from a total of 21 primary and secondary data sources. Of those, 1,059 (53%) were female. Equations for FEV1, FVC, the FEV1/FVC ratio, FEF between 25% and 75% of the FVC (FEF25-75%) and the FEF25-75%/FVC ratio were generated for white-, black-, and brown-skinned children. The logarithms for height and age, together with skin color, were the best predictors of FEV1 and FVC. The reference values obtained were significantly higher than those employed in the equations currently in use in Brazil, for predicted values, as well as for the lower limit of normality, particularly in children with self-reported black or brown skin. CONCLUSIONS New spirometric equations were generated for Brazilian children 3-12 years of age, in the three skin-color categories defined. The equations currently in use in Brazil seem to underestimate the lung function of Brazilian children 3-12 years of age and should be replaced by the equations proposed in this study.OBJECTIVE To assess the impact that implementing a checklist during daily multidisciplinary rounds has on the duration of invasive mechanical ventilation (IMV) and length of ICU stay. METHODS This was a non-randomized clinical trial in which the pre-intervention and post-intervention duration of IMV and length of ICU stay were evaluated in a total of 466 patients, including historical controls, treated in three ICUs of a hospital in the city of Caxias do Sul, Brazil. We evaluated 235 and 231 patients in the pre-intervention and post-intervention periods, respectively. The following variables were studied age; gender; cause of hospitalization; diagnosis on admission; comorbidities; the Simplified Acute Physiology Score 3; the Sequential Organ Failure Assessment score; days in the ICU; days on IMV; reintubation; readmission; in-hospital mortality; and ICU mortality. RESULTS After the implementation of the checklist, the median (interquartile range) for days in the ICU and for days on IMV decreased from 8 (4-17) to 5 (3-11) and from 5 (1-12) to 2 ( less then 1-7), respectively, and the differences were significant (p ≤ 0.001 for both). CONCLUSIONS The implementation of the checklist during daily multidisciplinary rounds was associated with a reduction in the duration of IMV and length of ICU stay among the patients in our sample.OBJECTIVE Understand limitations and possibilities in university management performed by nursing managers of the undergraduate nursing course of a public university. METHOD A qualitative study with theoretical and methodological framework anchored in the Grounded Theory. Data collection took place between May and September 2016, and the studied scenario was the Nursing Department of a public university in southern Brazil. RESULTS The entrepreneurial profile and the leadership in interpersonal relations were highlighted among the possibilities, in addition to the co-responsibility in raising public resources to solve the university educational demands; as limitations, the scarcity of financial resources and the high demand for bureaucratic activities which have repercussions on the slowness of university public management processes. CONCLUSION The nursing manager experiences limitations through their actions and interactions with people, and recognizes possibilities in the structure and processes of coordinating issues of collective interest in the university educational context.
