Aim: Although bulk fill composites have been widely used as restorative material, there is no consensus regarding the best clinical protocol in terms of composite technique and adhesive system. Therefore, this clinical trial evaluated the clinical performance of bulk fill composites for class I restorations under different protocols. Methods: A randomized clinical trial including 155 class I restorations was conducted using different adhesive systems: conventional technique (phosphoric acid + conventional three-step adhesive system) (Group 1, 2 and 3); or self-etching adhesive system (Groups 4, 5 and 6). Control groups 1 and 4 were restored with conventional composite; groups 2 and 5 with low viscosity bulk fill and conventional composite as occlusal coverage; groups 3 and 6 with high viscosity bulk fill. The FDI criteria was used for clinical evaluation at baseline and after 6 months. Results: All groups showed good clinical performance. At baseline, the adhesive system did not affect postoperative hypersensitivity. After 6 months, group 5 showed a significant reduction in color and translucency; group 6 a reduction in terms of anatomical form and for postoperative sensitivity and an improvement in patient satisfaction (p

Background: The prevalence of metabolic syndrome (MS) varies according to the different definitions available for clinical practice. The study aimed to estimate and compare the prevalence of MS according to the definitions of the American Heart Association (AHA)/National Heart, Lung, and Blood Institute (NHBI), International Diabetes Federation (IDF), and Joint Interim Statement (JIS) in a sample of climacteric women in Brazil. Methods: A population-based cross-sectional study, using a probabilistic sampling by clusters, involved 874 climacteric women. Clinical and anthropometric variables were acquired while fasting, and MS was defined according to three recommendations. To define the agreement between different definitions on MS, we calculated the sensitivity and specificity for the diagnosis of MS based on AHA/NHBI and IDF in relationship to the JIS definition. Results: The prevalence of MS was 56.9% according to the AHA/NHBI definition, 61.6% by the IDF, and 64.8% by the JIS definition, without statistical significance. When prevalence of MS was stratified by climacteric stages, the ability of the different definitions identifying MS was also similar among groups. It was observed that the MS definition proposed by AHA/NHBI identified 87.4% of MS cases from the total cases diagnosed by JIS, with agreement levels by the Kappa index of 0.835. The IDF detected 95.3% of MS cases compared to the JIS definition and the agreement level was 0.934. Conclusions: The study indicates a high prevalence of MS in climacteric women regardless of the definition used (AHA/NHBI, IDF e JIS). We did not observe significant divergences between definitions.

This study aimed to evaluate the validity and precision of the International Physical Activity Questionnaire (IPAQ) for climacteric women using computational intelligence techniques. The instrument was applied to 873 women aged between 40 and 65 years. Considering the proposal to regroup the set of data related to the level of physical activity of climacteric women using the IPAQ, we used 2 algorithms: Kohonen and k-means, and, to evaluate the validity of these clusters, 3 indexes were used: Silhouette, PBM and Dunn. The questionnaire was tested for validity (factor analysis) and precision (Cronbach's alpha). The Random Forests technique was used to assess the importance of the variables that make up the IPAQ. To classify these variables, we used 3 algorithms: Suport Vector Machine, Artificial Neural Network and Decision Tree. The results of the tests to evaluate the clusters suggested that what is recommended for IPAQ, when applied to climacteric women, is to categorize the results into two groups. The factor analysis resulted in three factors, with factor 1 being composed of variables 3 to 6; factor 2 for variables 7 and 8; and factor 3 for variables 1 and 2. Regarding the reliability estimate, the results of the standardized Cronbach's alpha test showed values between 0.63 to 0.85, being considered acceptable for the construction of the construct. In the test of importance of the variables that make up the instrument, the results showed that variables 1 and 8 presented a lesser degree of importance and by the analysis of Accuracy, Recall, Precision and area under the ROC curve, there was no variation when the results were analyzed with all IPAQ variables but variables 1 and 8. Through this analysis, we concluded that the IPAQ, short version, has adequate measurement properties for the investigated population.

This study aims to investigate the prevalence and factors associated with abdominal obesity in climacteric women assisted at Family Health Strategy units of the city of Montes Claros, State of Minas Gerais, Brazil. It is a cross-sectional analytical study. The women were selected by probabilistic sampling from August 2014 to August 2015. A questionnaire containing information referring to sociodemographic and economic characteristics, behavioral characteristics and clinical data was used. To estimate abdominal obesity, the measure of circumference ≥ 88 cm was considered. To analyze the association between abdominal obesity and the independent variables, a bivariate analysis was performed by means of Pearson’s chi-square test (p≤0.25). Subsequently, a multiple Poisson regression analysis with robust variance was performed, through which prevalence ratios with level of significance of 5% (p

This study aims to investigate the association between health conditions and overweight in climacteric women assisted by primary care professionals. It is a cross-sectional study conducted with 874 women from 40 to 65 years of age, selected by probabilistic sampling between August 2014 and August 2015. In addition to the outcome variable, other variables such as overweight/obesity, sociodemographic, reproductive, clinical, eating and behavioural factors were evaluated. Descriptive analyses of the variables investigated through their frequency distributions were performed. Then, bivariate analyses were performed through Poisson regression. For the multiple analyses, the hierarchical Poisson regression was used to identify factors associated with overweight/obesity in the climacteric period. The prevalence of overweight/obesity was 74%. Attending public school (PR: 1.30 - 95% CI 1.14 - 1.50), low schooling (PR: 1.11 - 95% CI 1.01 - 1.23), gout (PR: 1.18 - 95% CI 1.16-1.44), kidney disease (PR: 1.18 - 95% CI 1.05 - 1.32), metabolic syndrome - MS (PR: 1.19 - 95% CI 1.05 - 1.34) and fat intake (PR: 1.12 - 95% CI 1.02 - 1.23) were considered risk factors for overweight. Having the first birth after 18 years (PR: 0.89 - 95% CI 0.82 to 0.97) was shown to be a protective factor for overweight and obesity. The presence of overweight and obesity is associated with socio-demographic, reproductive, clinical and eating habits.

Background Health education actions are strategic actions aimed at health promotion. Moreover, better health education practices have been linked to comprehensive care developed by primary health services. Aim To understand the perception of mothers about the health education developed by the Primary Health Care (PHC) services. Design We adopted a qualitative research approach, conducted using semi-structured interviews, and assuming, as the theoretical reference, the attributes derived from PHC. Pregnant women and mothers of children under 1 year old attended by Brazilian Family Health teams were included. Results Eight pregnant women and twelve mothers of children under 1 year of age participated in the study. These mothers perceive educational actions as necessary only for primiparous mothers. They value the guidance of informal networks and maternity hospitals to the detriment of primary services, and they do not adhere to care that conflicts with their previous knowledge. The evidence shows that the educational actions of the primary health services do not adequately respond to the attributes of community orientation, family focus, and cultural competence. Conclusion It is necessary to modify the educational practices in order to incorporate and value the existing knowledge in the territory, thereby adapting the care guidelines to the local context.
