- Anaphylaxis is a life-threatening allergic reaction which is rapid in onset. Adolescents living with anaphylaxis risk often lack the knowledge and skills required to safely manage their condition or talk to friends about it. We designed an educational intervention comprising group discussion around videos of simulated anaphylaxis scenarios and a mobile application containing video-based branching anaphylaxis narratives. We trialed the intervention with 36 nut allergic adolescents. At 1-year follow-up participants had improved adrenaline auto-injector skills and carriage, disease- and age-specific Quality of Life and confidence in anaphylaxis management. At 3-year follow-up adrenaline carriage improved further and confidence remained higher. Participants expressed how the education session was a turning point in taking control of their allergy and how the app facilitated sharing about anaphylaxis with others. We contribute insights regarding design of mobile self-care and peer-support applications for health in adolescence, and discuss strengths and limitations of video-based mobile health interventions.

- During a series of HST/STIS observations of Eta Carinae and associatedejecta, we noticed a peculiar emission filament located a few arcsecondsnorth of the central source. While bright in nebular standards, it issubmerged in a sea of scattered starlight until moderately highdispersion, long-slit spectroscopy with the STIS (R 8000) brings theemission lines out. The initial spectrum, centered on 6768A with theSTIS G750M grating, led to identification of twenty lines fromsingly-ionized species including [Sr II], [Fe II], [Ti II], [Ni II], [MnII], and [Co II] (Zethson, etal., 2001, AJ 122, 322). No Balmer emissionis detected from this filament and the Fe II 2507,9 lines, known to bepumped by Lyman alpha radiation in other regions near the centralsource, are not detected. Followup observations have led to detection ofhundreds more emission lines from iron group elements in neutral andsingly-ionized states. Thus far all are excited by less than 10 eV. Thispeculiar nebular emission is thought to be due to very intense stellarradiation, stripped of uv flux shortward of Lyman alpha, bathing aneutral structure. We are systematically identifying the many lines(over 90% identified) and measuring line intensities that will then bemodeled to determine excitation mechanisms, temperature and density. Two[Sr II] and two Sr II lines have now been measured. Bautista, etal. (inpreparation) have modeled the strontium flux ratios and find that largeradiation fluxes and/or high strontium abundances may account for thedetected emission. These observations were supported by STIS GTO fundingand GO funding through the STScI.
