Developing an On-Line Interactive Health Psychology Module.

On-line teaching material in health psychology was developed which ensured a range of students could access appropriate material for their course and level of study. This material has been developed around the concept of smaller 'content chunks' which can be combined into whole units of learning (topics), and ultimately, a module. On the basis of the underlying philosophy that the medium is part of the message, we considered interactivity to be a key element in engaging the student with the material. Consequently, the key aim of this development was to stimulate and engage students, promoting better involvement with the academic material, and hence better learning. It was hoped that this was achieved through the development of material including linked programmes and supporting material, small Java Scripts and basic email, forms and HTML additions. This material is outlined as are some of the interactive activities introduced, and the preliminary student and tutor experience described

The Endogenous Th17 Response in NO<inf>2</inf>-Promoted Allergic Airway Disease Is Dispensable for Airway Hyperresponsiveness and Distinct from Th17 Adoptive Transfer

Severe, glucocorticoid-resistant asthma comprises 5-7% of patients with asthma. IL-17 is a biomarker of severe asthma, and the adoptive transfer of Th17 cells in mice is sufficient to induce glucocorticoid-resistant allergic airway disease. Nitrogen dioxide (NO2) is an environmental toxin that correlates with asthma severity, exacerbation, and risk of adverse outcomes. Mice that are allergically sensitized to the antigen ovalbumin by exposure to NO2 exhibit a mixed Th2/Th17 adaptive immune response and eosinophil and neutrophil recruitment to the airway following antigen challenge, a phenotype reminiscent of severe clinical asthma. Because IL-1 receptor (IL-1R) signaling is critical in the generation of the Th17 response in vivo, we hypothesized that the IL-1R/Th17 axis contributes to pulmonary inflammation and airway hyperresponsiveness (AHR) in NO2-promoted allergic airway disease and manifests in glucocorticoid-resistant cytokine production. IL-17A neutralization at the time of antigen challenge or genetic deficiency in IL-1R resulted in decreased neutrophil recruitment to the airway following antigen challenge but did not protect against the development of AHR. Instead, IL-1R-/- mice developed exacerbated AHR compared to WT mice. Lung cells from NO2-allergically inflamed mice that were treated in vitro with dexamethasone (Dex) during antigen restimulation exhibited reduced Th17 cytokine production, whereas Th17 cytokine production by lung cells from recipient mice of in vitro Th17-polarized OTII T-cells was resistant to Dex. These results demonstrate that the IL-1R/Th17 axis does not contribute to AHR development in NO2-promoted allergic airway disease, that Th17 adoptive transfer does not necessarily reflect an endogenously-generated Th17 response, and that functions of Th17 responses are contingent on the experimental conditions in which they are generated. © 2013 Martin et al

Health promotion services for lifestyle development within a UK hospital – Patients' experiences and views

<p>Abstract</p> <p>Background</p> <p>UK public health policy requires hospitals to have in place health promotion services which enable patients to improve their health through adopting healthy behaviours, i.e. health education. This study investigated hospitalised patients' experiences of health education for smoking, alcohol use, diet, physical activity, and weight, and their views concerning the appropriateness of hospitals as a setting for the delivery of health education services.</p> <p>Methods</p> <p>Recently discharged adult hospital patients (n = 322) were sent a questionnaire asking about their smoking, alcohol use, diet, physical activity, and weight. For each of these risk factors, participants were asked whether they agreed with screening for the risk factor, whether they received health education, whether it was "helpful", and if they wanted to change their behaviour. Participants were also asked a set of general questions concerning health education within hospitals.</p> <p>Results</p> <p>190 patients responded (59%). Over 80% agreed with screening for all risk factors. 80% of smokers, 52% consuming alcohol above recommended limits, 86% of obese, 66% consuming less than five fruit and vegetables a day, and 61% of physically inactive participants wanted to change their respective behaviour. However only a third reported receiving health education. While over 60% of patients wanted health education around discharge, the majority of those receiving health education did so at admission. The majority agreed that "hospital is a good place for patients to receive" health education (87%) and that "the hospital should provide patients with details of community organisations that provide" health education (83%). Only a minority (31%) reported a preference for health education from their GP instead of hospital.</p> <p>Conclusion</p> <p>While the delivery of health education to patients within hospital was poor, hospitals are viewed by patients as an appropriate, and in some cases preferred setting for the screening of risk factors and delivery of health education.</p

DESI Complete Calibration of the Color-Redshift Relation (DC3R2): Results from early DESI data

We present initial results from the Dark Energy Spectroscopic Instrument (DESI) Complete Calibration of the Color-Redshift Relation (DC3R2) secondary target survey. Our analysis uses 230k galaxies that overlap with KiDS-VIKING $ugriZYJHK_s$ photometry to calibrate the color-redshift relation and to inform photometric redshift (photo-z) inference methods of future weak lensing surveys. Together with Emission Line Galaxies (ELGs), Luminous Red Galaxies (LRGs), and the Bright Galaxy Survey (BGS) that provide samples of complementary color, the DC3R2 targets help DESI to span 56% of the color space visible to Euclid and LSST with high confidence spectroscopic redshifts. The effects of spectroscopic completeness and quality are explored, as well as systematic uncertainties introduced with the use of common Self Organizing Maps trained on different photometry than the analysis sample. We further examine the dependence of redshift on magnitude at fixed color, important for the use of bright galaxy spectra to calibrate redshifts in a fainter photometric galaxy sample. We find that noise in the KiDS-VIKING photometry introduces a dominant, apparent magnitude dependence of redshift at fixed color, which indicates a need for carefully chosen deep drilling fields, and survey simulation to model this effect for future weak lensing surveys.Comment: 19 pages, 16 figures, submitted to MNRAS, interactive visualizations at https://jmccull.github.io/DC3R2_Overvie

Family Communication in Inherited Cardiovascular Conditions in Ireland

Over 100,000 individuals living in Ireland carry a mutated gene for an inherited cardiac condition (ICC), most of which demonstrate an autosomal dominant pattern of inheritance. First-degree relatives of individuals with these mutations are at a 50 % risk of being a carrier: disclosing genetic information to family members can be complex. This study explored how families living in Ireland communicate genetic information about ICCs and looked at the challenges of communicating information, factors that may affect communication and what influence this had on family relationships. Face to face interviews were conducted with nine participants using an approved topic guide and results analysed using thematic analysis. The participants disclosed that responsibility to future generations, gender, proximity and lack of contact all played a role in family communication. The media was cited as a source of information about genetic information and knowledge of genetic information tended to have a positive effect on families. Results from this study indicate that individuals are willing to inform family members, particularly when there are children and grandchildren at risk, and different strategies are utilised. Furthermore, understanding of genetics is partially regulated not only by their families, but by the way society handles information. Therefore, genetic health professionals should take into account the familial influence on individuals and their decision to attend genetic services, and also that of the media.postprin

Defining ourselves:Personal bioinformation as a tool of narrative self-conception

Where ethical or regulatory questions arise about an individual’s interests in accessing bioinformation about herself (such as findings from screening or health research), the value of this information has traditionally been construed in terms of its clinical utility. It is increasingly argued, however, that the “personal utility” of findings should also be taken into account. This article characterizes one particular aspect of personal utility: that derived from the role of personal bioinformation in identity construction. The suggestion that some kinds of information are relevant to identity is not in itself new. However, the account outlined here seeks to advance the debate by proposing a conception of the relationship between bioinformation and identity that does not depend on essentialist assumptions and applies beyond the narrow genetic contexts in which identity is customarily invoked. The proposal is that the identity-value of personal bioinformation may be understood in terms of its instrumental role in the construction of our narrative identities, specifically that its value lies in helping us to develop self-narratives that support us in navigating our embodied existences. I argue that this narrative conception provides useful insights that are pertinent to the ethical governance of personal bioinformation. It illuminates a wider range of ethical considerations in relation to information access; it accounts for variations in the utility of different kinds of information; and it highlights that the context in which information is conveyed can be as important as whether it is disclosed at all. These arguments are illustrated using an example drawn from psychiatric neuroimaging research

Finishing the euchromatic sequence of the human genome

The sequence of the human genome encodes the genetic instructions for human physiology, as well as rich information about human evolution. In 2001, the International Human Genome Sequencing Consortium reported a draft sequence of the euchromatic portion of the human genome. Since then, the international collaboration has worked to convert this draft into a genome sequence with high accuracy and nearly complete coverage. Here, we report the result of this finishing process. The current genome sequence (Build 35) contains 2.85 billion nucleotides interrupted by only 341 gaps. It covers ∼99% of the euchromatic genome and is accurate to an error rate of ∼1 event per 100,000 bases. Many of the remaining euchromatic gaps are associated with segmental duplications and will require focused work with new methods. The near-complete sequence, the first for a vertebrate, greatly improves the precision of biological analyses of the human genome including studies of gene number, birth and death. Notably, the human enome seems to encode only 20,000-25,000 protein-coding genes. The genome sequence reported here should serve as a firm foundation for biomedical research in the decades ahead
