Awareness of Meningococcal disease among travelers from the United Kingdom to the meningitis belt in Africa

Meningococcal disease causes considerable morbidity and has a high case-fatality rate. In the United Kingdom, the meningococcal quadrivalent vaccine is recommended for travelers visiting the meningitis belt of Africa. We analyzed 302 responses to a cross-sectional study conducted in 2010 of travelers who had visited the meningitis belt recently or were shortly due to travel there. Using the results of an online questionnaire, we assessed knowledge and understanding of meningococcal disease and likelihood of uptake of meningococcal immunization before travel. Meningococcal vaccine uptake was 30.1%. Although global scores in the questionnaire did not correlate with vaccine uptake, knowledge of the meningitis belt and knowledge of certain key symptoms or signs were statistically associated with high vaccine uptake. We conclude that improved education of travelers may improve vaccine uptake before travel to the meningitis belt in Africa

The factors influencing car use in a cycle-friendly city: the case of Cambridge.

Encouraging people out of their cars and into other modes of transport, which has major advantages for health, the environment and urban development, has proved difficult. Greater understanding of the influences that lead people to use the car, particularly for shorter journeys, may help to achieve this. This paper examines the predictors of car use compared with the bicycle to explore how it may be possible to persuade more people to use the bicycle instead of the car. Multivariable logistic regression was used to examine the socio-demographic, transport and health-related correlates of mode choice for work, shopping and leisure trips in Cambridge, a city with high levels of cycling by UK standards. The key findings are that commuting distance and free workplace parking were strongly associated with use of the car for work trips, and car availability and lower levels of education were associated with car use for leisure, shopping and short-distanced commuting trips. The case of Cambridge shows that more policies could be adopted, particularly a reduction in free car parking, to increase cycling and reduce the use of the car, especially over short distances

Session 2A: \u3cem\u3ePanel Discussion: Developing Post-Incident Risk Communication Guidelines for Intentional Water Contamination Events\u3c/em\u3e

This panel will discuss emerging findings from a US EPA-funded research project intended to improve risk communication for post-incident decontamination and clearance activities associated with intentional contamination of a water system. The session will center around Phase II of the study, which focuses on extending the Phase I case study findings that were presented at last year’s KWRRI Symposium, to identify ways in which disparate stakeholder groups in metropolitan areas differentially perceive risk and subsequent risk communication efforts

Sub-wavelength diffraction-free imaging with low-loss metal-dielectric multilayers

We demonstrate numerically the diffraction-free propagation of sub-wavelength sized optical beams through simple elements built of metal-dielectric multilayers. The proposed metamaterial consists of silver and a high refractive index dielectric, and is designed using the effective medium theory as strongly anisotropic and impedance matched to air. Further it is characterised with the transfer matrix method, and investigated with FDTD. The diffraction-free behaviour is verified by the analysis of FWHM of PSF in the function of the number of periods. Small reflections, small attenuation, and reduced Fabry Perot resonances make it a flexible diffraction-free material for arbitrarily shaped optical planar elements with sizes of the order of one wavelength.Comment: 5 pages, 4 figure

An examination of writing pauses in the handwriting of children with Developmental Coordination Disorder.

This article has been made available through the Brunel Open Access Publishing Fund.Difficulties with handwriting are reported as one of the main reasons for the referral of children with Developmental Coordination Disorder (DCD) to healthcare professionals. In a recent study we found that children with DCD produced less text than their typically developing (TD) peers and paused for 60% of a free-writing task. However, little is known about the nature of the pausing; whether they are long pauses possibly due to higher level processes of text generation or fatigue, or shorter pauses related to the movements between letters. This gap in the knowledge-base creates barriers to understanding the handwriting difficulties in children with DCD. The aim of this study was to characterise the pauses observed in the handwriting of English children with and without DCD. Twenty-eight 8-14 year-old children with a diagnosis of DCD participated in the study, with 28 TD age and gender matched controls. Participants completed the 10 min free-writing task from the Detailed Assessment of Speed of Handwriting (DASH) on a digitising writing tablet. The total overall percentage of pausing during the task was categorised into four pause time-frames, each derived from the literature on writing (250 ms to 2 s; 2-4 s; 4-10 s and >10 s). In addition, the location of the pauses was coded (within word/between word) to examine where the breakdown in the writing process occurred. The results indicated that the main group difference was driven by more pauses above 10 s in the DCD group. In addition, the DCD group paused more within words compared to TD peers, indicating a lack of automaticity in their handwriting. These findings may support the provision of additional time for children with DCD in written examinations. More importantly, they emphasise the need for intervention in children with DCD to promote the acquisition of efficient handwriting skill

Isolated brachydactyly type E caused by a HOXD13 nonsense mutation: a case report

<p>Abstract</p> <p>Background</p> <p>Brachydactyly type E (BDE; MIM#113300) is characterized by shortening of the metacarpal, metatarsal, and often phalangeal bones, and predominantly affects postaxial ray(s) of the limb. BDE may occur as an isolated trait or as part of a syndrome. Isolated BDE is rare and in the majority of cases the molecular pathogenesis has so far not been resolved. Originally, the molecular cause of isolated BDE has been unravelled in 2 families and shown to result from heterozygous missense mutations in the homeodomain of the <it>HOXD13 </it>gene. Since the initial manuscript, one further <it>HOXD13 </it>mutation has been reported only in a single family manifesting isolated BDE.</p> <p>Case Presentation</p> <p>In this paper, we report on a Polish family exhibiting isolated BDE caused by a novel nonsense heterozygous <it>HOXD13 </it>mutation. We investigated a Polish female proband and her father, both affected by isolated BDE, in whom we identified a nonsense heterozygous mutation c.820C > T(p.R274X) in the <it>HOXD13 </it>gene. So far, only two missense <it>HOXD13 </it>substitutions (p.S308C and p.I314L), localized within the homeodomain of the HOXD13 transcription factor, as well as a single nonsense mutation (p.E181X) were associated with BDE. Both missense changes were supposed to alter DNA binding affinity of the protein.</p> <p>Conclusion</p> <p>The variant p.R274X identified in our proband is the fourth <it>HOXD13 </it>mutation, and the second truncating (nonsense) mutation, reported to result in typical isolated BDE. We refer our clinical and molecular findings to the previously described <it>HOXD13 </it>associated phenotypes and mutations.</p

Handwriting speed in children with Developmental Coordination Disorder: Are they really slower?

Changes resulting from the publishing process, such as peer review, editing, corrections, structural formatting, and other quality control mechanisms may not be reflected in this document. Changes may have been made to this work since it was submitted for publication. Copyright @ 2013 Elsevier B.V.Handwriting difficulties are often included in descriptions of Developmental Coordination Disorder (DCD). They are cited as the most common reason for referral to health professionals following parent and teacher concerns about slow and untidy writing. The aim of this study was to compare handwriting performance in English children with and without DCD across a range of writing tasks, to gain a better understanding of the nature of ‘slowness’ so commonly reported. Twenty-eight 8–14 year-old children with a diagnosis of DCD participated in the study, with 28 typically developing age and gender matched controls. Participants completed the four handwriting tasks from the Detailed Assessment of Speed of Handwriting (DASH) and wrote their own name; all on a digitising writing tablet. The number of words written, speed of pen movements and the time spent pausing during the tasks were calculated. The findings confirmed what many professionals report, that children with DCD produce less text than their peers. However, this was not due to slow movement execution, but rather a higher percentage of time spent pausing. Discussion centres on the understanding of the pausing phenomenon in children with DCD and areas for further research.Oxford Brookes Universit

Session 2A: \u3cem\u3eDeveloping Post-Incident Risk Communication Guidelines for Intentional Water Contamination Events\u3c/em\u3e

This panel will discuss a US EPA-funded research project intended to improve risk communication for post-incident decontamination and clearance activities associated with intentional contamination of a water system. The study incorporates two complementary methods conducted in successive phases. The recently-completed first phase included robust case study analyses of risk communication related to recent and significant contamination incidents. The second phase, which is currently underway, will identify ways in which disparate stakeholder groups in a metropolitan area differentially perceive risk and subsequent risk communication efforts

Keeping Allergen Names Clear and Defined

The World Health Organization/International Union of Immunological Societies (WHO/IUIS) Allergen Nomenclature Sub-Committee was established in 1986 by leading allergists to standardize names given to proteins that cause IgE-mediated reactions in humans. The Sub-Committee’s objective is to assign unique names to allergens based on a critical analysis of confidentially submitted biochemical and clinical data from researchers, often prior to publication to preserve consistency. The Sub-Committee maintains and revises the database as the understanding of allergens evolves. This report summarizes recent developments that led to updates in classification of cockroach group 1 and 5 allergens to animal as well as environmental and occupational allergens. Interestingly, routes, doses, and frequency of exposure often affects allergenicity as does the biochemical properties of the proteins and similarity to self and other proteins. Information required by the Sub-Committee now is more extensive than previously as technology has improved. Identification of new allergens requires identification of the amino acid sequence and physical characteristics of the protein as well as demonstration of IgE binding from subjects verified by described clinical histories, proof of the presence of the protein in relevant exposure substances, and demonstration of biological activity (skin prick tests, activation of basophils, or mast cells). Names are assigned based on taxonomy with the abbreviation of genus and species and assignment of a number, which reflects the priority of discovery, but more often now, the relationships with homologous proteins in related species
