Anthropometric evaluation and micronutrients intake in patients submitted to laparoscopic Roux-en-Y gastric bypass with a postoperative period of ≥1 year

Backgroung - Bariatric surgery is indicated as the most effective treatment for morbid obesity; the Roux-en-Y gastric bypass (RYGB) is considered the procedure of choice. However, nutritional deficiency may occur in the postoperative period as a result of reduced gastric capacity and change in nutrients absorption in the gastrointestinal tract. The prescription of vitamin and mineral supplementation is a common practice after RYGB; however, it may not be sufficient to prevent micronutrient deficiencies. The aim of this study was to quantify the micronutrient intake in patients undergoing RYGB and verify if the intake of supplementation would be enough to prevent nutritional deficiencies. Methods - The study was conducted on 60 patients submitted to RYGB. Anthropometric, analytical, and nutritional intake data were assessed preoperatively and 1 and 2 years postoperatively. The dietary intake was assessed using 24-h food recall; the values of micronutrients evaluated (vitamin B12, folic acid, iron, and calcium) were compared to the dietary reference intakes (DRI). Results - There were significant differences (p < 0.05) between excess weight loss at the first and second year (69.9 ± 15.3 vs 9.6 ± 62.9 %). In the first and second year after surgery, 93.3 and 94.1 % of the patients, respectively, took the supplements as prescribed. Micronutrient deficiencies were detected in the three evaluation periods. At the first year, there was a significant reduction (p < 0.05) of B12, folic acid, and iron intake. Conclusions - Despite taking vitamin and mineral supplementation, micronutrient deficiencies are common after RYGB. In the second year after surgery, micronutrient intake remains below the DRI.

Epidemiologic transition in northern Angola: discussion of cumulative results from CISA (Health Research Centre of Angola)

The 41 years of armed conflict (1961 to 2002) resulted in a poor development of the health care and education infrastructures, and forced the relocation of people to safer places, namely major urban cities like Luanda. This phase was characterized by typical demographic, nutritional and epidemiological profiles. With the end of this period Angola has been repeatedly ranked as one of the three fastest growing economies in the world, and along with the social stabilization and globalization, the country is facing the introduction of new medical technologies, improvement of health sys-tems and services, better access to them, and overall better quality of life. These changes could also be translating into socio-cultural, demographic and nutritional changes which in turn may leading to changes in the epidemiological profile of the country. Thus, the emergence of non-communicable diseases are likely to become an increasingly im-portant public health problem in Angola. Also, considering that several infectious diseases persist, our weakened health system will have to face a double burden. Thus, disease surveillance data on non-communicable diseases to determine their prevalence and impact, along with the major behavioural risk factors like consumption of tobacco, alcohol, diets and physical inactivity are urgently needed.

Demand for and availability of online support to stop smoking

OBJECTIVES: Estimate the frequency of online searches on the topic of smoking and analyze the quality of online resources available to smokers interested in giving up smoking. METHODS: Search engines were used to revise searches and online resources related to stopping smoking in Brazil in 2010. The number of searches was determined using analytical tools available on Google Ads; the number and type of sites were determined by replicating the search patterns of internet users. The sites were classified according to content (advertising, library of articles and other). The quality of the sites was analyzed using the Smoking Treatment Scale- Content (STS-C) and the Smoking Treatment Scale - Rating (STS-R). RESULTS: A total of 642,446 searches was carried out. Around a third of the 113 sites encountered were of the 'library' type, i.e. they only contained articles, followed by sites containing clinical advertising (18.6) and professional education (10.6). Thirteen of the sites offered advice on quitting directed at smokers. The majority of the sites did not contain evidence-based information, were not interactive and did not have the possibility of communicating with users after the first contact. Other limitations we came across were a lack of financial disclosure as well as no guarantee of privacy concerning information obtained and no distinction made between editorial content and advertisements. CONCLUSIONS: There is a disparity between the high demand for online support in giving up smoking and the scarcity of quality online resources for smokers. It is necessary to develop interactive, customized online resources based on evidence and random clinical testing in order to improve the support available to Brazilian smokers.

Using remote labs in education: two little ducks in remote experimentation

A book about remote labs and engineering education begs to begin with the question, “Why do engineering programs include lab work?” Although this may seem like a given and not worth discussing, whenever we’re faced with innovative ideas, it’s important to “put everything on the table” in order to reassess its value to our program or goals. What is it about lab work that is of value to students? Are there elements of traditional labs that we could let go of? Are there elements that we don’t want to lose? These questions can help us to clarify how and why labs are integrated into an engineering education program.

Advances and challenges in oral health after a decade of the “Smiling Brazil” Program

ABSTRACT OBJECTIVE To analyze oral health work changes in primary health care after Brazil’s National Oral Health Policy Guidelines were released. METHODS A literature review was conducted on Medline, LILACS, Embase, SciELO, Biblioteca Virtual em Saúde, and The Cochrane Library databases, from 2000 to 2013, on elements to analyze work changes. The descriptors used included: primary health care, family health care, work, health care policy, oral health care services, dentistry, oral health, and Brazil. Thirty-two studies were selected and analyzed, with a predominance of qualitative studies from the Northeast region with workers, especially dentists, focusing on completeness and quality of care. RESULTS Observed advances focused on educational and permanent education actions; on welcoming, bonding, and accountability. The main challenges were related to completeness; extension and improvement of care; integrated teamwork; working conditions; planning, monitoring, and evaluation of actions; stimulating people’s participation and social control; and intersectorial actions. CONCLUSIONS Despite the new regulatory environment, there are very few changes in oral health work. Professionals tend to reproduce the dominant biomedical model. Continuing efforts will be required in work management, training, and permanent education fields. Among the possibilities are the increased engagement of managers and professionals in a process to understand work dynamics and training in the perspective of building significant changes for local realities.

A mobile robot platform for open learning based on serious games and remote laboratories

Within the pedagogical community, Serious Games have arisen as a viable alternative to traditional course-based learning materials. Until now, they have been based strictly on software solutions. Meanwhile, research into Remote Laboratories has shown that they are a viable, low-cost solution for experimentation in an engineering context, providing uninterrupted access, low-maintenance requirements, and a heightened sense of reality when compared to simulations. This paper will propose a solution where both approaches are combined to deliver a Remote Laboratory-based Serious Game for use in engineering and school education. The platform for this system is the WebLab-Deusto Framework, already well-tested within the remote laboratory context, and based on open standards. The laboratory allows users to control a mobile robot in a labyrinth environment and take part in an interactive game where they must locate and correctly answer several questions, the subject of which can be adapted to educators' needs. It also integrates the Google Blockly graphical programming language, allowing students to learn basic programming and logic principles without needing to understand complex syntax.

Immunohistochemical molecular phenotypes of gastric cancer based on SOX2 and CDX2 predict patient outcome

Background Gastric cancer remains a serious health concern worldwide. Patients would greatly benefit from the discovery of new biomarkers that predict outcome more accurately and allow better treatment and follow-up decisions. Here, we used a retrospective, observational study to assess the expression and prognostic value of the transcription factors SOX2 and CDX2 in gastric cancer. Methods SOX2, CDX2, MUC5AC and MUC2 expression were assessed in 201 gastric tumors by immunohistochemistry. SOX2 and CDX2 expression were crossed with clinicopathological and follow-up data to determine their impact on tumor behavior and outcome. Moreover, SOX2 locus copy number status was assessed by FISH (N = 21) and Copy Number Variation Assay (N = 62). Results SOX2 was expressed in 52% of the gastric tumors and was significantly associated with male gender, T stage and N stage. Moreover, SOX2 expression predicted poorer patient survival, and the combination with CDX2 defined two molecular phenotypes, SOX2+CDX2- versus SOX2-CDX2+, that predict the worst and the best long-term patients’ outcome. These profiles combined with clinicopathological parameters stratify the prognosis of patients with intestinal and expanding tumors and in those without signs of venous invasion. Finally, SOX2 locus copy number gains were found in 93% of the samples reaching the amplification threshold in 14% and significantly associating with protein expression. Conclusions We showed, for the first time, that SOX2 combined with CDX2 expression profile in gastric cancer segregate patients into different prognostic groups, complementing the clinicopathological information. We further demonstrate a molecular mechanism for SOX2 expression in a subset of gastric cancer cases.

Educação alimentar infantil: potencialidades de estudantes de educação de infância

Resumo: Na promoção de comportamentos alimentares saudáveis ao longo da vida. que deve iniciar-se o mais precocemente possível, a educação alimentar é um elemento chave. O jardim-de-infância é um espaço efectivo na implementação de projectos de educação alimentar, onde os educadores de infância são actores imprescindíveis. Este estudo teve como objectivo desenvolver uma metodologia apropriada para identificar as capacidades de estudantes de educação de infância e avaliar as suas aptidões no contexto da educação alimentar infantil. A população alvo do estudo foram estudantes do 4ºano da licenciatura em educação de infância de instituições públicas e privadas da área metropolitana de Lisboa (n=287). Construiu-se um videograma, integrador dos domínios da aprendizagem (cognitivo e afectivo) e dos factores associados aos comportamentos em saúde (predisponentes, capacitadores e de esforço). A construção dos questionários estruturou-se em: conhecimentos-atitudes-comportamentos.Pretendia-se que os estudantes transmitissem a sua opinião, de acordo com os questionários.Os estudantes manifestaram conhecimentos, no âmbito da alimentação infantil e da utilidade e aplicabilidade da educação alimentar.Nenhum estudante apresentou conhecimentos negativos, numa escala de zero a 18 valores, 86,9% obtiveram uma classificação entre 11 e 17 valores e 13,1% a classificação máxima.A atitude dos estudantes revelou-se consensual com o desejável, 98,5% apresentaram atitudes positivas face aos aspectos estruturadores das actividades de educação alimentar.No domínio do "saber fazer" 51,0% dos estudantes demonstraram fragilidades no seu desempenho/comportamento. Em conclusão, a utilização do questionário demonstrou ser apropriado para a medição dos conhecimentos, das atitudes e como forma de os estudantes, após visionarem o videograma, espelharem o seu desempenho/comportamento face à representação do educador de infância. A taxa de resposta nunca foi inferior a 98,9% (n=284). No domínio dos conhecimentos, os estudantes manifestaram concepções positivas no campo da alimentação infantil e da educação alimentar. As atitudes enfatizaram-se no domínio afectivo, nos aspectos relacionais e comunicacionais. No domínio dos comportamentos, 91,8% dos estudantes apresentaram dificuldades na identificação dos aspectos menos correctos do desempenho dos actores do video, o que pode sugerir lacunas no âmbito do "saber fazer". Abstract:Nutrition education is key element to promote lifelong healthy eating behaviours and it must begin since early stages of life. Nursery schools are an effective space in the implementation of nutrition education projects, where the nursery teachers are indispensable actors. The aim of this study was to develop an appropriate methodology to identify nursery education student´s skills and evaluate their attitudes in the childhood nutrition education's context. The study's population were students of the 4th degree in private and public nursery education universities in Lisbon metropolitan area (n=287). A video integrator of learning domains (cognitive and affective) and of factors associated with health behaviours (predisposing, enabling and reinforcing) was developed. Questionnaire´s construction was structured in: knowledge-attitudes-behaviours.According to the questionnaires students were asked to transmit their opinion. Students revealed knowledge, in the scope of the childhood nutrition and in utility and applicability of nutrition education. No students presented negative results in knowledge ina zero - 18 scale; 86,9% students obtained a classification between 11 and 17 and the maximum classification was obtained by 13.1% students. Student's attitude was according to win the desirable, 98,5% student´s revealed positive attitudes in the nutrition education's structure aspects of chilhood activities.In the domain of the "know to do" 51,0% of students showed fragilities in their performance/behaviour. In conclusion, the questionnaire´s utilization confirm to be appropriated in measurement knowledge and attitudes and also, after watching the video, as a way for students reflect their performance/behaviour face to the nursery teacher´s representation. Answer´s rate was never lower than 98.9% (n=284). In the knowledge's domain students demonstrated positive conceptions in the childhood nutrition and nutrition education's fields. Attitudes were emphasized in the effective domain in the communication and relational aspects. In behaviour's domain 91.8% students presented difficulties in identifying the less correct aspects of the video actor's performance what may suggest gaps in the "know to do" scope.

Alimentação e saúde : uma abordagem epidemiológica de estudantes universitários

Resumo: A alimentação e o estado nutricional são factores determinantes do estado de saúde e sabe-se hoje que os mecanismos da patogénese de várias doenças crónicas não-transmissíveis podem ocorrer no início da idade adulta. A alimentação é influenciada por uma multiplicidade de factores, entre os quais se contam a importância atribuída à alimentação, o peso e imagem corporal e a percepção dos riscos associados à escolha de alimentos. Esta investigação teve como objectivos analisar, em estudantes universitários até aos 30 anos de idade, o estado nutricional, a importância atribuída a alimentação, as percepções do peso e da imagem corporal e a percepção do risco de doença relacionada com a alimentação. Os objectivos foram cumpridos através de dois desenhos de estudo distintos: estudo descritivo transversal e estudo de caso-controlo. Avaliou-se o peso, altura e os perímetros da cintura e da anca e construiu-se um questionário de auto-preenchimento para recolher a restante informação. Encontraram-se valores para a prevalência de obesidade e excesso de peso de, respectivamente, 6,5% e 24,3% e concluiu-se que existe uma percepção incorrecta do peso e da imagem corporal, mais frequente entre os indivíduos obesos. Os obesos também consideram a alimentação menos importante que os indivíduos normoponderais. A análise da percepção dos riscos revela que os inquiridos consideram que factores como a obesidade e a inactividade física são menos prejudiciais para a saúde do que factores como as alterações climáticas ou as radiações de telefones móveis. Verificaram-se também diferenças entre sexos nos parâmetros estudados: relativamente às mulheres, os homens sobrestimam mais frequentemente o peso e a imagem corporal, consideram a alimentação menos importante, julgam-se em menor risco de doença e classificam os factores de risco estudados como menos prejudiciais. Conclui-se que as estratégias de educação alimentar e de promoção da saúde devem considerar as diferenças registadas entre sexos e a importância atribuída à alimentação e as percepções do risco, do peso e da imagem corporal. Abstract: Nutrition and nutritional status are health determinants and it’s accepted that the mechanisms for the pathogenesis of several chronic non-communicable diseases can occur in early adult age. Nutrition is influenced by a large number of factors, including the value placed on food, weight and body image and the risk perception associated with food choice. Consequently, the analysis of the factors that can influence food behaviour and food choice in young adults can be useful for the control and prevention of nutrition related disease. The objectives of this research were to analyse, in college students up to 30 years of age, nutritional status, value placed on nutrition, weight and body image perceptions and the risk perception of nutrition related disease. Two study designs were used: cross-sectional and case-control. Weight, height and waist and hip circumference were measured and a questionnaire was built to collect the remaining information. Prevalences of 6,5% for obesity and 24,3% for excess weight were found, along with the existence of biased weight and body image perceptions, more frequent in obese subjects. Obese subjects also placed less value on nutrition than non-obese. Risk perception analysis shows that risk factors like obesity and physical inactivity are considered less hazardous than risk factors like climate changes and mobile phone radiation. Men, comparatively to women, overestimated more frequently their weight and body image, placed less value in nutrition, considered themselves less disease susceptible and classified the risk factors studied as less hazardous. The conclusions of this study show that nutrition education and health promotion strategies should consider the gender related differences reported and, also, the value placed on nutrition and weigh, body image and risk perceptions.

A teaching-learning sequence of colour informed by history and philosophy of science

In this work, we present a teaching-learning sequence on colour intended to a pre-service elementary teacher programme informed by History and Philosophy of Science. Working in a socio-constructivist framework, we made an excursion on the history of colour. Our excursion through history of colour, as well as the reported misconception on colour helps us to inform the constructions of the teaching-learning sequence. We apply a questionnaire both before and after each of the two cycles of action-research in order to assess students’ knowledge evolution on colour and to evaluate our teaching-learning sequence. Finally, we present a discussion on the persistence of deep-rooted alternative conceptions.
