title: Dietary patterns of Brazilian adolescents: results of the Brazilian National School-Based Health Survey (PeNSE)

description: The objectives of this study were to identify dietary patterns in Brazilian adolescents, describe their distributions in Brazil's State capitals and Federal District, and analyze the correlations with the Municipal Human Development Index (HDI-M). The study analyzed a sample of 60,954 ninth-graders from public and private schools who participated in the National School-Based Health Survey (PeNSE) in 2009. Cluster analysis was used to characterize dietary patterns. Three patterns were identified: healthy (27.7%), unhealthy (34.6%), and mixed (37.7%). Adolescents in the country's Southeast, South, and Central West regions showed a higher proportion of the healthy eating pattern. HDI-M showed a positive correlation with the healthy pattern and a negative correlation with the mixed pattern. The identification of different dietary patterns within and between regions and according to HDI-M highlights the need for better knowledge of each local context in terms of both the magnitude of events and the examination of determinants within these different realities.

title: PRODUCTION, CHARACTERIZATION AND USAGE OF A NOVEL DISULFONIC ACID-FUNCTIONALIZED IONIC LIQUID AS A HIGHLY EFFICIENT AND DUAL-FUNCTIONAL CATALYST FOR THE SYNTHESIS OF 1,8-DIOXO-9,10-DIARYL-DECAHYDROACRIDINES

description: We have produced a novel ionic liquid {N,N,N',N'-tetramethylethylene-diaminium-N,N'-disulfonic acid trifluoroacetate ([TMEDSA][TFA]2)}, and identified it by analysis of 1H NMR, 13C NMR, 19F NMR, mass, TG (thermogravimetry) and DSC (differential scanning calorimetry) data. Then, we have applied [TMEDSA][TFA]2 as a dual-functional catalyst for the production of 1,8-dioxo-9,10-diaryl-decahydroacridines by the multi-component reaction of dimedone with arylaldehydes and primary amines. Furthermore, we have proposed a plausible and attractive mechanism based on dual-functionality of the catalyst. Due to dual-functionality of [TMEDSA][TFA]2 (possessing acidic and basic sites), and also possessing two sites of each, it was highly effective and general, and produced the products in high yields.

title: Critical incidents involving Semiology during practical activities of nursing undergraduates

description: ABSTRACT Objective: To identify critical incidents (situations, behaviors and feelings) during practical activities, involving knowledge and skills related to the discipline of Semiology and Semiotics. Method: Descriptive research using the critical incident technique, with the Snow Ball technique for the selection of participants and an instrument for collection of data. The reports were categorized according to the elements of the critical incident (situations, behaviors and feelings). Results: A total of 62 reports from senior (n = 46), sophomore and junior (n = 16) students were analyzed. The students were predominantly female (90.3%). The majority described a situation of a physical examination, expressed mastery of the skills necessary for the activity and reported positive feelings. Conclusion: The reports showed that the knowledge and skills acquired in the discipline allowed for a development of practical activities with familiarity and positive feelings. The importance that the students attribute to the recognition of the activities by the professor, the patient and family stands out.

title: EVALUATION OF THE GRAPHENE OXIDE (GO) ROLE IN THE PHOTOCATALYTIC GENERATION OF HYDROGEN IN BINARY (GO-CdS) AND TERNARY (Pt-GO-CdS) SYSTEMS

description: Water splitting is a promising process to produce hydrogen from friendly feedstock and solar energy. In this work we have evaluated binary (GO-CdS) and ternary (Pt-GO-CdS) hybrid photocatalysts for hydrogen production assisted by visible light irradiation. Cadmium sulfide and composites with GO were prepared by sonochemical and thermal methods. GO addition took place by different strategies: during the synthesis or by mechanical mixture. A variety of configurations was tested and the best performance in hydrogen production among all materials was the ternary photocatalyst named Pt(GO/CdSTT), whose hydrogen production rate was 651 µmol gcat-1 h-1. Such material was obtained by thermal method with GO addition during the synthesis. Additionally, the XRD and Raman analyses have confirmed the GO photoreduction during photocatalytic hydrogen evolution.

title: Reproductive and vegetative behavior of hybrid jabuticaba tree under flowering induction

description: ABSTRACT Brazil is one of the countries with the greatest vegetal diversity in the world, especially for the Myrtaceae family, to which the jabuticaba tree belongs. Its fruits are of great acceptability, but it is little explored commercially, because it takes a long time to reach the production stage. This study aimed to evaluate the vegetative and reproductive behavior of hybrid jabuticaba trees under flowering induction treatments. A randomized block design was used, with the following treatments: calcium carbide, etefon, paclobutrazol, daily irrigation management and control. Growth and reproductive development data were evaluated. For vegetative growth, there was no difference among the treatments, demonstrating no negative effect. On the other hand, paclobutrazol showed to be the most promising treatment, because it anticipates flowering, is effective in induction and results in a higher production.

title: Symptoms of Depression, Anxiety and Stress in Drug Users undergoing Treatment in Therapeutic Communities

description: Abstract Symptoms of depression, anxiety and stress may interfere negatively in the progress of treatment of substance abusers. This study aimed to evaluate the levels of depression, anxiety and stress in men and women undergoing treatment for substance use disorder in therapeutic communities, relating such levels with the type of substance used and sociodemographic data. We used a Sociodemographic and Drug Use Data Questionnaire and the DASS-21. Participants included 115 men and 53 women on treatment (M=32 years; SD=8.7). Most were users of tobacco and crack, the latter associated with women. Tobacco and other drug users who were unemployed were associated with higher levels of depression, anxiety, and stress symptoms in the DASS-21. The results do not allow a causal relationship between the variables, but highlight the relevance of including in the treatments, strategies for smoking cessation and professional reintegration. Such strategies may help to reduce the symptoms evaluated by the DASS-21, improving living conditions for coping with substance use disorders.

title: INFLUENCE OF EXTRACTION PROCESS ON FLAVONOID CONTENT FROM Cnidoscolus quercifolius POHL (EUPHORBIACEAE) AND ANTIOXIDANT ACTIVITY

description: Cnidoscolus quercifolius Pohl is a Brazilian medicinal plant from Caatinga biome and possesses several pharmacological properties. Phytochemical investigations have attributed some of these properties to the presence of flavonoids. In this paper, we report the influence of the extraction process on the flavonoid content obtained from leaves of C. quercifolius and its antioxidant activity. A factorial design 22 was performed, using temperature and agitation as independent variables. Qualitative and quantitative analyzes of the extracts were performed by HPLC-DAD. Rutin and apigenin were identified in the extracts and chosen as analytical markers. Pareto chart and Surface response plots suggested that rutin content was increased up to 3.93 times when temperature was employed during the extraction process. However, apigenin content was significantly reduced in the method whose temperature or agitation were used (p&lt;0.05). A higher antioxidant activity was observed in extracts whose rutin extraction was favored, suggesting that this flavonoid contributes at least in part to the antioxidant potential of the species.

title: TEACHERS AND STUDENTS ON FACEBOOK: COLLABORATION AS A WAY OF POTENTIATING AGENCY

description: ABSTRACT: The aim of this study is to describe how the use of Facebook groups influence teachers and students to become collaborative agents. In order to understand how such process occurs, this article follows the Cultural-Historical Activity Theory principles (LEONTIEV, 1978; VYGOTSKY, 1987; ENGESTRÖM, 2015), and is methodologically based on the Critical Collaborative Research (MAGALHÃES, 1998). Data used in this study was collected from the newsfeed of six groups on Facebook, one group being composed by teachers and five groups with teachers and students, and from questionnaires that were answered by teachers and students in different moments. Data was analyzed following the socio-discursive interactionism (BRONCKART, 1999) and conversational analysis (KERBRAT-ORECCHIONI, 2006). Our results suggest that participants present an evolution in relation to agency and, due to the collaborative aspect of the research, it was possible to expand the activities beyond the initial research goals.

title: Effectiveness of the monitoring program for ensuring the quality of water treated for dialysis in the state of São Paulo

description: ABSTRACT Introduction: Chronic kidney failure is a disease that affects the functions of the kidneys and can cause irreversible kidney failure over time. Among the main factors that cause this disease are hypertension and diabetes mellitus. The number of patients presenting this clinical condition has been increasing in Brazil, leading to an increase in renal replacement therapy, such as hemodialysis. Material and methods: In the state of São Paulo, a joint action between the Adolfo Lutz Institute, the Sanitary Surveillance Center, and the Sanitary Surveillance Groups have promoted the State Program for the Monitoring of Water Treated for Dialysis since 2007 to evaluate the chemical and microbiological quality of the water used in dialysis in compliance with the current legislation. Objective: This study aimed to evaluate the monitoring program developed between 2010 and 2016 as a tool for corrective action when unsatisfactory results are observed. Results: The level of satisfactory results during the period varied from 85.8 to 98.0%, indicating an increase in the adequacy of the dialysis services in producing water with adequate quality for patient health. Conclusion: The design adopted in the state monitoring program is highly effective based on new collections after the joint actions of the Sanitary Surveillance System and the State Dialysis Services.

title: Femoral fractures in elderly Brazilians: a spatial and temporal analysis from 2008 to 2012

description: Fractures in the elderly (≥ 60 years) have a major public health impact and take a heavy social and economic toll. This article aimed to describe spatial and time trends in femoral fractures among elderly men and women in all regions of Brazil. Bayesian descriptive analyses of spatial and time series were performed on data obtained from the Hospital Information System of the Brazilian Unified National Health System, using Poisson regression for femoral fractures in individuals 60 years of age or older from 2008 to 2012. There were more than 181,000 femoral fractures during this period, predominantly in women, without important spatial correlations or temporal differences. Despite the lack of temporal and spatial correlations, the number of femoral fractures in elderly Brazilians was high, with heavy financial and social costs. Public health policies are urgently needed to control predisposing factors for femoral fractures in elderly Brazilians.
