Growth and carbon turnover of Piaractus mesopotamicus Holmberg, 1887 (Osteicthyes: Characidae): contribution of extruded feed and natural food.

Piaractus mesopotamicus, is a fish usually farmed in semi-intensive systems with access to natural food and supplementary feed. This study evaluates effects of feed allowance on the productive performance, carbon turnover and proportions of nutrient (carbon) contribution of feed and natural food for the growth of pacu. Juvenile fish were stocked in fiberglass tanks and fed to 100, 75, 50, 25, 0% apparent satiety (ApS), with a practical, extruded (C4 photosynthetic pathway) feed in a randomized design trial (n=3); plankton production for simulated semi-intensive farming system condition was induced by chemical fertilization. A control treatment was set up in tanks devoid of natural food. Data on muscle stable carbon isotope ratios were used to study carbon turnover using a relative growth-based model. Low variation of the δ13C impaired fitting a turnover model curve for the 0 and 25 % ApS treatments. Fish of the 100% and 75% ApS treatments reached circa 95% and 82.85% of the carbon turnover, respectively. Extruded feed was the main nutrient source for the growth of pacu in the semi-intensive, simulated farming condition. The current study contributes to the knowledge of the relationship between feeding rates and carbon turnover rates in the pacu muscle.

Microencapsulation of Bacillus subtilis and oat ß-glucan and their application as a synbiotic in fish feed.

To improve survival during storage and exposure to adverse conditions, Bacillus subtilis was microencapsulated with oat ß-glucan by spray-drying technology. The characterisation of the microcapsules was designed to compare free and microencapsulated cells through exposure to simulated gastric fluids (SGF) throughout storage for 90 days at different temperatures. The characterisation included analysis of efficiency, morphology, moisture, water activity, hygroscopicity, particle size, and zeta potential. The microcapsules presented a particle size of 1.5 ± 0.34 µm and an encapsulation efficiency of 77.9 ± 3.06%. After SGF, the survival of microencapsulated cells was 8.4 ± 0.07 log CFU mL-1 while that of free cells was 7.6 ± 0.06 log CFU mL-1. After 90 days of storage, only microencapsulated cells remained above 6 log-unit of viability. In conclusion, spray-drying technique combined with the addition of oat ß-glucan proved to be an efficient method to protect B. subtilis under storage and SGF with potential application in fish feed.

Food and Nutrition Surveillance System: temporal trend of coverage and nutritional status of adults registered on the system, Brazil, 2008-2019. / Sistema de Vigilância Alimentar e Nutricional: tendência temporal da cobertura e estado nutricional de adultos registrados, 2008-2019.

OBJECTIVE: To analyze the temporal trend of Food and Nutrition Surveillance System (SISVAN) coverage and nutritional status of adults undergoing follow-up in the Brazilian Primary Health Care, 2008-2019. METHODS: This was an ecological time series study using data on Brazilian macro-regions. The annual percent change in the classification of nutritional status and total coverage was estimated using the Prais-Winsten regression model. RESULTS: A total of 115,034,534 records were identified in the period. Coverage increased from 5.0% in 2008 to 10.6% in 2019, with an annual change of 8.4%, 95% confidence interval (95%CI 6.7;10.0). Obesity and overweight showed a rising trend between 2008 and 2019, with an annual change of 6.4% (95%CI 5.3;7.3) and (1.8%; 95%CI 1.2;2.5) respectively, while underweight (-7.0%; 95%CI -8.0;-6.1) and eutrophy (-3.8%; 95%CI -4.1;-3.4) decreased in the period. CONCLUSION: There was an improvement in SISVAN coverage, with an increase in overweight and obesity among the population studied.

Feed intake and gene expression of appetite-regulating hormones in Salminus brasiliensis fed diets containing soy protein concentrate.

Dourado (Salminus brasiliensis) is a large carnivorous fish with high commercial value for which sustainable aquaculture relies on the substitution of expensive dietary animal protein sources in aquafeeds, in particular fish meal (FM), by cheaper plant protein, such as soy protein concentrate (SPC). This study aimed at evaluating feed intake and gene expression of appetite- regulating hormones [orexin, cocaine and amphetamine regulated transcript (CART), leptin, cholecystokinin (CCK) and peptide YY (PYY)] in the intestine, pyloric caeca and hypothalamus of juvenile dourado fed diets containing graded levels of SPC and FM as dietary protein sources for a period of three weeks. Increasing dietary plant protein contents reduced daily feed consumption and the expressions of the anorexigenic hormone CCK in the anterior intestine and in pyloric caeca and PYY in pyloric caeca. No changes were detected in the hypothalamic expression of appetite-regulating hormones, suggesting that gastrointestinal hormones are more involved in the decrease in feeding induced by plant protein diets than central appetite-regulating systems.

Renal Health: Providing Information and Technological Tools to Empower Patients to Live Better with Kidney Disease.

Chronic kidney disease (CKD) is a growing Public Health problem. Recent evidence points that low education and poor socio-economic conditions are associated with higher risk of developing CKD and progressing to dialysis or transplantation need. Hence patient empowerment through health education and qualification with technological tools that allows better treatment adherence may play an important role in the achievement of optimal clinical outcomes. The Renal Health is a multidisciplinary project created at the University of Fortaleza, northeast Brazil, in 2015, aiming to create novel educational material and technological tools for people with CKD, in different treatment modalities, including dialysis and transplant. The products developed so far in the project include an application for smartphones aiming to help patients in dialysis and transplant in their treatments, including schedule for medications, with alarms, water ingestion control, laboratory tests results, and medical appointments' agenda, besides all information regarding CKD. The other tools include a medication box, an insole for weight control (both are in the prototype phase), connection with smartbands (for vital signs monitoring) and multimedia educational tools, including a profile in the Instagram and a channel in YouTube. Since the first release of the application in the virtual stores, there were more than 1,000 downloads, predominantly in Brazil, although the app is also available in English and Spanish. All these tools represent innovative ways of patient empowerment and may be increasingly present in daily life. Further studies are required to assess the impact of these tools in patients' outcomes, including CKD progression and mortality.

Evaluation of the 'Gestação' application from the perspective of semiotics: pregnant women's views. / Avaliação do aplicativo "Gestação" na perspectiva da semiótica: o olhar das gestantes.

Evaluating health-related applications is necessary for their adequacy and dissemination in society. The GestAção application was evaluated based on the opinion of 13 pregnant women followed up in prenatal care consultations at three public health services and at a private institution in Fortaleza, Ceará, Brazil. Data emerged from an evaluation carried out from June to December 2017, including semi-structured interviews. Data were analyzed from content analysis in thematic and semiotic modality. Thus, the theme "meanings attributed to the application by pregnant women" emerged, which is associated with the following cores of meaning: provision of safe and diverse information; possibility of changing behavior and motivations for using the application. It is considered that semiotics allowed to understand the meanings attributed to the application from the interaction of pregnant women with the tool. The GestAção application was considered satisfactory, motivating to use, informative, safe and promoter of changes in the context of gestational health. Participants' views allow the evaluated technology to compose strategies aimed at promoting health care for pregnant women.

A ferramenta foi avaliada positivamente pelos participantes, com Índice de Validação de Conteúdo médio de 0,88. Os avaliadores apontaram, dentre outras funcionalidades, a capacidade da ferramenta em promover interatividade, mobilização e engajamento social, além de contribuir com a captação e a fidelização de doadores de sangue.

Abstract Blood donation is a social practice that helps treat diseases and maintain public health. The DoeSangue application was designed and developed to support donor recruitment and loyalty, strengthening health promotion and social engagement. We aimed to assess the DoeSangue application from the perspective of hematology and hemotherapy experts. A methodological, applied and qualitative research was carried out from September 2015 to July 2017 in Fortaleza, Ceará. The study was based on Participatory Interaction Design associated with Symbolic Interactionism. After conducting the first two steps, application design and development in a laboratory and assessment by donor users, the application was validated by eight experts from the Fortaleza's public blood center. For data collection, the 'application validation form with experts' was used based on a Likert-type scale, and a focus group was conducted. The tool was positively assessed by participants, with an average Content Validation Index of 0.88. Evaluators pointed out, among other features, the tool's ability to promote interactivity, mobilization and social engagement, in addition to contributing to gathering and loyalty of blood donors.

Avaliação do aplicativo "Gestação" na perspectiva da semiótica: o olhar das gestantes / Evaluation of the 'Gestação' application from the perspective of semiotics: pregnant women's views

Resumo A avaliação de aplicativos voltados à saúde é necessária para a sua adequação e disseminação na sociedade. O aplicativo GestAção foi avaliado com base na opinião de 13 gestantes acompanhadas em consultas pré-natais, em três serviços públicos de saúde e em uma instituição privada, em Fortaleza, Ceará, Brasil. Os dados emergiram do processo avaliativo realizado de junho a dezembro de 2017, incluindo entrevistas semiestruturadas, tendo sido analisados a partir da análise de conteúdo na modalidade temática e da Semiótica, resultando no tema "significados atribuídos ao aplicativo pelas gestantes", a qual se associa aos seguintes núcleos de sentido: fornecimento de informações seguras e diversificadas; possibilidade de mudança de comportamento e motivações para a utilização do aplicativo. Considera-se que a Semiótica permitiu compreender os significados atribuídos ao aplicativo, a partir da interação das gestantes com a ferramenta, indicando o GestAção como satisfatório, motivador ao uso, informativo, seguro e promotor de mudanças no contexto da saúde gestacional. O olhar das participantes possibilita que a tecnologia avaliada possa compor as estratégias voltadas à promoção e aos cuidados à saúde das gestantes.

Abstract Evaluating health-related applications is necessary for their adequacy and dissemination in society. The GestAção application was evaluated based on the opinion of 13 pregnant women followed up in prenatal care consultations at three public health services and at a private institution in Fortaleza, Ceará, Brazil. Data emerged from an evaluation carried out from June to December 2017, including semi-structured interviews. Data were analyzed from content analysis in thematic and semiotic modality. Thus, the theme "meanings attributed to the application by pregnant women" emerged, which is associated with the following cores of meaning: provision of safe and diverse information; possibility of changing behavior and motivations for using the application. It is considered that semiotics allowed to understand the meanings attributed to the application from the interaction of pregnant women with the tool. The GestAção application was considered satisfactory, motivating to use, informative, safe and promoter of changes in the context of gestational health. Participants' views allow the evaluated technology to compose strategies aimed at promoting health care for pregnant women.

The Renal Health Instagram: An Analysis of Comments.

Chronic kidney disease (CKD) is a Public Health problem affecting a considerable number of patients worldwide. CKD treatment is complex and requires patients' education. Based on this we have created technological tools, including an application for smartphones and a profile on Instagram (Renal Health) aiming to educate patients to self-monitor and cope with their disease, to increase adherence to treatment. In this study, we have analyzed the spontaneous feedbacks patients, and other people have posted on the Renal Health Instagram (comments) to investigate which information was needed the most by which types of patients. During the first 15 months since the release of this profile, there were 3380 followers, a total of 449 posts, with 36,079 "likes". Most of the followers were patients and parents, they gave spontaneous testimonials of their experiences with having kidney disease, and were thankful for the information provided and for the response we gave to their questions. From the analysis of the comments, we found that information on nutrition, physical activities and kidney transplant were the most discussed and valued. Our results also showed that the main use of this medium for dialysis and transplant patients was to share their experience. The Renal Health Instagram was considered a good digital platform of trusted information for both patients and the general population and also a space for sharing experiences in the context of kidney disease epidemics.

Resiliência: uma análise a partir das características sociodemográficas da população brasileira / Resilience: an analysis based on the sociodemographic characteristics of the Brazilian population / Resiliencia: análisis de las características sociodemográficas de la población brasileña

Objetivou-se analisar o efeito de dados sociodemográficos sobre o nível de resiliência de uma parcela da população brasileira. Para tanto, contou-se com uma amostra nacional não probabilística composta por 2.038 participantes, que responderam à Escala de Resiliência desenvolvida por Wagnild e Young. Os dados foram analisados por meio de estatística descritiva e bivarida com auxílio do software SPSS (Statistical Package for Social Science). Entre os resultados, verificou-se uma média geral baixa nos índices de resiliência (M = 124,60; DP = 22,69). Constatou-se também indicativos de que pessoas com determinadas características sociodemográficas têm maior tendência à resiliência: pessoas com religião, com maior nível de escolaridade, divorciados/casados, aposentados, sem piercing, não fumante, sem histórico de desistência ou repetição em anos escolares. Conclui-se que tais características podem estar relacionadas à capacidade da pessoa ser resiliente, mas não ser determinante, no nível de resiliência. Essas informações são primordiais para compreender os fatores que predispõem à resiliência da população. (AU)

The objective of this study was to analyze the effect of sociodemographic data on the level of resilience of a portion of the Brazilian population. For this purpose, a non-probabilistic national sample composed of 2,038 participants answered the Resilience Scale developed by Wagnild and Young. Data were analyzed using descriptive and bivariate statistics with the help of SPSS (Statistical Package for Social Sciences) software. Among the results, there was a low overall mean in resilience indices (M = 124.60, SD = 22.69). There were also indications that people with certain sociodemographic characteristics tend to be more resilient: people who are religious, with a higher education level, divorced / married, retired, without piercing, non- smoker, without a history of dropout or repetition in school years. It can be concluded that such characteristics may be related to a person's ability to be resilient, but not determinant, in the level of resilience. This information is essential to understand the factors that predispose the population to resilience. (AU)
