Nutritional guide for a modern woman: a strategy for health education

"In the present article, we introduce a Health Education instrument that stems from a refection on the lay knowledge, salutogenic habits and daily nutritional practices of modern women in our current society. We developed a guide aimed at modern women, where the different food groups and food hygiene and safety measures are addressed. The guide includes eleven original pictograms that help the reader to locate and look up specific issues. The guide employs the label reading and interpretation principles, following the nutrition traffic-light internationally instituted, for it renders scientific information on nutrition clear and accessible to the general population. We believe that using this guide as a central strategy in health promotion will lead its users to adopt essential changes in their eating patterns and, in so doing, contribute to prevent diseases associated to bad eating habits. We also emphasize the role of mass media in spreading the conveyed information."

Semi-supervised and compound classification of network traffic

This paper presents a new semi-supervised method to effectively improve traffic classification performance when very few supervised training data are available. Existing semisupervised methods label a large proportion of testing flows as unknown flows due to limited supervised information, which severely affects the classification performance. To address this problem, we propose to incorporate flow correlation into both training and testing stages. At the training stage, we make use of flow correlation to extend the supervised data set by automatically labelling unlabelled flows according to their correlation to the pre-labelled flows. Consequently, a traffic classifier achieves excellent performance because of the enhanced training data set. At the testing stage, the correlated flows are identified and classified jointly by combining their individual predictions, so as to further boost the classification accuracy. The empirical study on the real-world network traffic shows that the proposed method significantly outperforms the state-of-the-art flow statistical feature based classification methods.

Ethical considerations in preventive interventions for bipolar disorder

AIM: Early intervention and prevention of serious mental disorders such as bipolar disorder has the promise of decreasing the burden associated with these disorders. With increasing early and preventive intervention efforts among cohorts such as those with a familial risk for bipolar disorder, there is a need to examine the associated ethical concerns. The aim of this review was to examine the ethical issues underpinning the clinical research on pre-onset identification and preventive interventions for bipolar disorder.

METHODS: We undertook a PubMed search updated to November 2014 incorporating search terms such as bipolar, mania, hypomania, ethic*(truncated), early intervention, prevention, genetic and family.

RESULTS: Fifty-six articles that were identified by this method as well as other relevant articles were examined within a framework of ethical principles including beneficence, non-maleficence, respect for autonomy and justice. The primary risks associated with research and clinical interventions include stigma and labelling, especially among familial high-risk youth. Side effects from interventions are another concern. The benefits of preventive or early interventions were in the amelioration of symptoms as well as the possibility of minimizing disability, cognitive impairment and progression of the illness. Supporting the autonomy of individuals and improving access to stigma-free care may help moderate the potential challenges associated with the risks of interventions.

CONCLUSIONS: Concerns about the risks of early identification and pre-onset interventions should be balanced against the potential benefits, the individuals' right to choice and by improving availability of services that balance such dilemmas.

Statistical detection of online drifting twitter spam

Spam has become a critical problem in online social networks. This paper focuses on Twitter spam detection. Recent research works focus on applying machine learning techniques for Twitter spam detection, which make use of the statistical features of tweets. We observe existing machine learning based detection methods suffer from the problem of Twitter spam drift, i.e., the statistical properties of spam tweets vary over time. To avoid this problem, an effective solution is to train one twitter spam classifier every day. However, it faces a challenge of the small number of imbalanced training data because labelling spam samples is time-consuming. This paper proposes a new method to address this challenge. The new method employs two new techniques, fuzzy-based redistribution and asymmetric sampling. We develop a fuzzy-based information decomposition technique to re-distribute the spam class and generate more spam samples. Moreover, an asymmetric sampling technique is proposed to re-balance the sizes of spam samples and non-spam samples in the training data. Finally, we apply the ensemble technique to combine the spam classifiers over two different training sets. A number of experiments are performed on a real-world 10-day ground-truth dataset to evaluate the new method. Experiments results show that the new method can significantly improve the detection performance for drifting Twitter spam.

The sensitivity of mapping methods to reference data quality:training supervised image classifications with imperfect reference data

The accuracy of a map is dependent on the reference dataset used in its construction. Classification analyses used in thematic mapping can, for example, be sensitive to a range of sampling and data quality concerns. With particular focus on the latter, the effects of reference data quality on land cover classifications from airborne thematic mapper data are explored. Variations in sampling intensity and effort are highlighted in a dataset that is widely used in mapping and modelling studies; these may need accounting for in analyses. The quality of the labelling in the reference dataset was also a key variable influencing mapping accuracy. Accuracy varied with the amount and nature of mislabelled training cases with the nature of the effects varying between classifiers. The largest impacts on accuracy occurred when mislabelling involved confusion between similar classes. Accuracy was also typically negatively related to the magnitude of mislabelled cases and the support vector machine (SVM), which has been claimed to be relatively insensitive to training data error, was the most sensitive of the set of classifiers investigated, with overall classification accuracy declining by 8% (significant at 95% level of confidence) with the use of a training set containing 20% mislabelled cases.

Consumers knowledge about dietary fibre : Results of a survey questionnaire in Hungary and Romania

Dietary fi bres (DFs) are essential components of the balanced diet. Even though the adequate level of their consumption can be ensured from several natural (e.g. fruit, vegetables, legumes) and ‘artifi cial’ sources (e.g. functional foods), the consumed levels are below the recommendations. To analyse the Hungarian and Romanian consumers’ knowledge level, their perceptions of the health benefi ts associated with fi bre, as well as the recognition of the potential information sources, a survey questionnaire was conducted with the total of 713 consumers. Results showed that the level of knowledge about DFs was not adequate. Internet was found to be widely used and identifi ed as one of the most appropriate information sources to encourage the consumption of DF. It was a favourable result that three-quarter of the respondents was interested in the topic of healthy food consumption; however, just less than half of them took into consideration the label information during their shopping decisions. To increase the consumption of DF and to support the responsibility and conscious consumer decisions steps must to be done (e.g. education of children, pointing out of the sources). For this purpose, modern information technology and communication channels fi tting to the consumers’ cultural and personal particularities can be utilized.

Knowledge and attitudes towards dietary fibers - romania vs other european countries

Aim: The aim of our study was to evaluate the Romanian’s knowledge and attitudes regarding dietary fibers compared with other European countries. Materials and methods: We made a cross-sectional survey (part of multinational project from CI&DETS Research Centre, Instituto Politecnico Viseu, Portugal, with reference PROJ/CI&DETS/2014/0001) based on a questionnaire applied in 2015, over 670 Romanian consumers, focused on the attitudes and knowledge towards ingestion of foods rich in fibers. We used the software SPSS for statistics. Results: Our results showed that the knowledge about dietary fibers and also the ingestion of food products rich in fibers were low. The female participants ate more whole grains and fruits than males and pay more attention to food labelling, the Romanian people prefer to stay and eat home than at restaurants especially in rural areas, and the knowledge about fiber’s benefits was significantly related to high education and urban location. Comparing to other European countries, Romania had the highest level of knowledge about dietary fibers definition followed by Portugal, Turkey and Hungary, but the lowest regarding the fibers importance for health after Macedonia, Turkey and Latvia. Conclusion: We sustain the needs for more efficient community interventions and proper information about the importance of dietary fibers for our health and also for the dissemination of the nutritional standards among Romanian population.

Romanian Knowledge and Attitudes regarding Dietary Fibers

Presently, the scientists recognize the health benefits of food fibers in the menu and also plant food sources are at high interest both for general population and food companies. The food companies are responsible for a clear nutrition labelling that will assist consumers to make informed and healthy choices and health providers has to inform the population about the benefits of fibers.The aim of our study was to evaluate the Romanian knowledge and attitudes regarding dietary fibers from food products. We made a qualitative survey based on a questionnaire applied in 2015, over a period of 6 months, over 670 Romanian consumers. It was focused on testing the attitudes and knowledge towards ingestion of foods rich in fibers. For all data analysis we used the software SPSS, from IBM Inc. Our results showed that the knowledge about dietary fibers and also the ingestion of food products rich in fibers were low, and most of the subjects didn’t have any interest to read the nutritional information from food labels. The female participants ate more whole grains and fruits than males and pay more attention to food labelling. Romanian people prefer to stay and eat home than at restaurants especially in rural areas, and the knowledge about fibers benefits was significantly related to education and urban location. We underline the needs for more efficient community interventions and proper information about the importance of dietary fibers for our health and also to improve and disseminate nutritional standards and diet recommendation among population.

Atitudes da população portuguesa em relação à fibra alimentar

Introdução: A fibra dietética (FD) tem feito parte da dieta humana desde há milénios, embora os seus benefícios tenham sido reconhecidos, principalmente, nas últimas décadas. Objetivos: Porque a FD é um componente importante de uma dieta saudável, o objetivo deste trabalho foi avaliar os hábitos de consumo dos Portugueses, bem como o seu conhecimento sobre os alimentos ricos em fibras e as suas atitudes em relação à rotulagem dos alimentos. Métodos: Foi realizado um estudo descritivo transversal usando uma amostra não-probabilística de 382 participantes. Resultados: Os resultados mostraram que a ingestão de alimentos ricos em fibras, como frutas, vegetais e cereais, foi muito menor do que a ingestão recomendada. Os resultados também indicaram que a maioria das pessoas não presta a atenção desejada à rotulagem de alimentos ou à informação nutricional. Conclusões: O nível geral de conhecimento sobre FD foi considerado insatisfatório, e, portanto, é necessário mais educação nutricional e desenvolver esforços para informar as pessoas acerca da importância da FD como parte da sua dieta diária.

Att bekämpa det onda eller främja det goda : Fyra verksamhetsperspektiv på individer i våldsbejakandemiljöer samt preventionsarbete runt dessa

To fight evil or promote good: Four organizational perspectives on individuals inviolent environments and prevention work around them. The purpose of this article is to examine organizational understandings and perceptions that can affect the current work with defectors from and members in violent and extremist environments. The empirical material consists primarily of answers to open questions in a survey, where professionals from four organizations are represented: social services, school, police and politics. The material is analyzed with direct qualitative content analysis and shows two contradict approaches to the problem; one that argues for ”fighting the evil” and another that argues for ”promoting the good”. The theoretical framework presented is Erving Goffmans’ frame analysis, Howard S. Beckers’ labelling process and Ingrid Sahlins’ discussion about different kinds of prevention strategies. The results show how organizational understandings and perceptions are far from uniform but rather disparate, and also that assumptions made by professionals have wide implications – often related to morally based approaches grounded on notions of good and evil.

Comparison of medication policies to guide nursing practice across seven Victorian health services

Objectives The objective of this paper is to review and compare the content of medication management policies across seven Australian health services located in the state of Victoria. Methods The medication management policies for health professionals involved in administering medications were obtained from seven health services under one jurisdiction. Analysis focused on policy content, including the health service requirements and regulations governing practice. Results and Conclusions The policies of the seven health services contained standard information about staff authorisation, controlled medications and poisons, labelling injections and infusions, patient self-administration, documentation and managing medication errors. However, policy related to individual health professional responsibilities, single- and double-checking medications, telephone orders and expected staff competencies varied across the seven health services. Some inconsistencies in health professionals' responsibilities among medication management policies were identified. What is known about the topic? Medication errors are recognised as the single most preventable cause of patient harm in hospitals and occur most frequently during administration. Medication management is a complex process involving several management and treatment decisions. Policies are developed to assist health professionals to safely manage medications and standardise practice; however, co-occurring activities and interruptions increase the risk of medication errors. What does this paper add? In the present policy analysis, we identified some variation in the content of medication management policies across seven Victorian health services. Policies varied in relation to medications that require single- and double-checking, as well as by whom, nurse-initiated medications, administration rights, telephone orders and competencies required to check medications. What are the implications for practitioners? Variation in medication management policies across organisations is highlighted and raises concerns regarding consistency in governance and practice related to medication management. Lack of practice standardisation has previously been implicated in medication errors. Lack of intrajurisdictional concordance should be addressed to increase consistency. Inconsistency in expectations between healthcare services may lead to confusion about expectations among health professionals moving from one healthcare service to another, and possibly lead to increased risk of medication errors.

Analysis of mammalian cell proliferation and macromolecule synthesis using deuterated water and gas chromatography-mass spectrometry.

Deuterated water (²H₂O), a stable isotopic tracer, provides a convenient and reliable way to label multiple cellular biomass components (macromolecules), thus permitting the calculation of their synthesis rates. Here, we have combined ²H₂O labelling, GC-MS analysis and a novel cell fractionation method to extract multiple biomass components (DNA, protein and lipids) from the one biological sample, thus permitting the simultaneous measurement of DNA (cell proliferation), protein and lipid synthesis rates. We have used this approach to characterize the turnover rates and metabolism of a panel of mammalian cells in vitro (muscle C2C12 and colon cancer cell lines). Our data show that in actively-proliferating cells, biomass synthesis rates are strongly linked to the rate of cell division. Furthermore, in both proliferating and non-proliferating cells, it is the lipid pool that undergoes the most rapid turnover when compared to DNA and protein. Finally, our data in human colon cancer cell lines reveal a marked heterogeneity in the reliance on the de novo lipogenic pathway, with the cells being dependent on both 'self-made' and exogenously-derived fatty acid.

The influence of eco-label knowledge and trust on pro-environmental consumer behaviour in an emerging market

Consumers are increasingly concerned about the negative environmental implications of purchasing goods, which in turn shape their behaviour. Yet, there are indications that consumers do not always act on these concerns, causing an attitude–behaviour gap. For consumers to make ecologically responsible purchases, they need relevant product environmental information. Therefore, marketers and firms are increasingly integrating more detailed environmental information in their offerings, including eco-labels with externally validated information. This study integrates consumers’ knowledge and trust in eco-labels with their environmental knowledge to determine how these affect pro-environmental consumer behaviour (PECB). The findings suggest environmental and eco-label knowledge is positively associated with attitudes towards the environment, and that positive environmental attitudes and trust in eco-labels affect PECB. This implies that firms, policy-makers and accreditation organisations (i.e. labelling) can educate consumers about eco-labels and the environment to increase PECB. Such strategies will also build consumer knowledge and trust in eco-labels, necessary for facilitating PECB.

Investigating Angiotensin II in cardiac remodelling and the counter-regulatory actions of Angiotensin-(1-9)

Cardiovascular diseases (CVDs) including, hypertension, coronary heart disease and heart failure are the leading cause of death worldwide. Hypertension, a chronic increase in blood pressure above 140/90 mmHg, is the single main contributor to deaths due to heart disease and stroke. In the heart, hypertension results in adaptive cardiac remodelling, including LV hypertrophy to normalize wall stress and maintain cardiac contractile function. However, chronic increases in BP results in the development of hypertensive heart disease (HHD). HHD describes the maladaptive changes during cardiac remodelling which result in reduced systolic and diastolic function and eventually heart failure. This includes ventricular dilation due to eccentric hypertrophy, cardiac fibrosis which stiffens the ventricular wall and microvascular rarefaction resulting in a decrease in coronary blood flow albeit an increase in energy demand. Chronic activation of the renin-angiotensin-system (RAS) with its effector peptide angiotensin (Ang)II plays a key role in the development of hypertension and the maladaptive changes in HHD. Ang II acts via the angiotensin type 1 receptor (AT1R) to mediate most of its pathological actions during HHD, including stimulation of cardiomyocyte hypertrophy, activation of cardiac fibroblasts and increased collagen deposition. The counter-regulatory axis of the RAS which is centred on the ACE2/Ang-(1-7)/Mas axis has been demonstrated to counteract the pathological actions of Ang II in the heart and vasculature. Ang-(1-7) via the Mas receptor prevents Ang II-induced cardiac hypertrophy and fibrosis and improves cardiac contractile function in animal models of HHD. In contrast, less is known about Ang-(1-9) although evidence has demonstrated that Ang-(1-9) also antagonises Ang II and is anti-hypertrophic and anti-fibrotic in animal models of acute cardiac remodelling. However, so far it is not well documented whether Ang-(1-9) can reverse established cardiac dysfunction and remodelling and whether it is beneficial when administered chronically. Therefore, the main aim of this thesis was to assess the effects of chronic Ang-(1-9) administration on cardiac structure and function in a model of Ang II-induced cardiac remodelling. Furthermore, this thesis aimed to investigate novel pathways contributing to the pathological remodelling in response to Ang II. First, a mouse model of chronic Ang II infusion was established and characterised by comparing the structural and functional effects of the infusion of a low and high dose of Ang II after 6 weeks. Echocardiographic measurements demonstrated that low dose Ang II infusion resulted in a gradual decline in cardiac function while a high dose of Ang II induced acute cardiac contractile dysfunction. Both doses equally induced the development of cardiac hypertrophy and cardiac fibrosis characterised by an increase in the deposition of collagen I and collagen III. Moreover, increases in gene expression of fibrotic and hypertrophic markers could be detected following high dose Ang II infusion over 6 weeks. Following this characterisation, the high dose infusion model was used to assess the effects of Ang-(1-9) on cardiac structural and functional remodelling in established disease. Initially, it was evaluated whether Ang-(1-9) can reverse Ang II-induced cardiac disease by administering Ang-(1-9) for 2-4 weeks following an initial 2 week infusion of a high dose of Ang II to induce cardiac contractile dysfunction. The infusion of Ang-(1-9) for 2 weeks was associated with a significant improvement of LV fractional shortening compared to Ang II infusion. However, after 4 weeks fractional shortening declined to Ang II levels. Despite the transient improvement in cardiac contractile function, Ang-(1-9) did not modulate blood pressure, LV hypertrophy or cardiac fibrosis. To further investigate the direct cardiac effects of Ang-(1-9), cardiac contractile performance in response to Ang-(1-9) was evaluated in the isolated Langendorff-perfused rat heart. Perfusion of Ang-(1-9) in the paced and spontaneously beating rat heart mediated a positive inotropic effect characterised by an increase in LV developed pressure, cardiac contractility and relaxation. This was in contrast to Ang II and Ang-(1-7). Furthermore, the positive inotropic effect to Ang-(1-9) was blocked by the AT1R antagonist losartan and the protein kinase A inhibitor H89. Next, endothelial-to-mesenchymal transition (EndMT) as a novel pathway that may contribute to Ang II-induced cardiac remodelling was assessed in Ang II-infused mice in vivo and in human coronary artery endothelial cells (HCAEC) in vitro. Infusion of Ang II to mice for 2-6 weeks resulted in a significant decrease in myocardial capillary density and this was associated with the occurrence of dual labelling of endothelial cells for endothelial and mesenchymal markers. In vitro stimulation of HCAEC with TGFβ and Ang II revealed that Ang II exacerbated TGF-induced gene expression of mesenchymal markers. This was not correlated with any changes in SMAD2 or ERK1/2 phosphorylation with co-stimulation of TGFβ and Ang II. However, superoxide production was significantly increased in HCAEC stimulated with Ang II but not TGFβ. Finally, the role of Ang II in microvesicle (MV)-mediated cardiomyocyte hypertrophy was investigated. MVs purified from neonatal rat cardiac fibroblasts were found to contain detectable Ang II and this was increased by stimulation of fibroblasts with Ang II. Treatment of cardiomyocytes with MVs derived from Ang II-stimulated fibroblasts induced cardiomyocyte hypertrophy which could be blocked by the AT1R antagonist losartan and an inhibitor of MV synthesis and release brefeldin A. Furthermore, Ang II was found to be present in MVs isolated from serum and plasma of Ang II-infused mice and SHRSP and WKY rats. Overall, the findings of this thesis demonstrate for the first time that the actions of Ang-(1-9) in cardiac pathology are dependent on its time of administration and that Ang-(1-9) can reverse Ang II-induced cardiac contractile dysfunction by acting as a positive inotrope. Furthermore, this thesis demonstrates evidence for an involvement of EndMT and MV signalling as novel pathways contributing to Ang II-induced cardiac fibrosis and hypertrophy, respectively. These findings provide incentive to further investigate the therapeutic potential of Ang-(1-9) in the treatment of cardiac contractile dysfunction in heart disease, establish the importance of novel pathways in Ang II-mediated cardiac remodelling and evaluate the significance of the presence of Ang II in plasma-derived MVs.
