Increasingly, narrative and creative arts approaches are being used to enhance recovery after traumatic brain injury (TBI). Narrative and arts-based approaches congruent with Indigenous storytelling may therefore provide benefit during the transition from hospital to home for some Indigenous TBI patients. This qualitative study explored the use and impact of this approach as part of a larger, longitudinal study of TBI transition with Indigenous Australians.
A combined narrative and arts-based approach was used with one Indigenous Australian artist to describe his transition experiences following TBI. Together with the researchers and filmmaking team, the artist was involved in aspects of the process. The artist contributed two paintings, detailing the story of his life and TBI. Based on the artworks, a film was co-created. Following the viewing of the film, impacts of the narrative and arts-based process were examined through semi-structured interviews with the artist, a service provider and a family member. Multiple sources of data were used in the final thematic analysis including transcripts of the interviews and filming, paintings (including storylines) and researcher notes.
Positive impacts from the process for the artist included positive challenge; healing and identity; understanding TBI and raising awareness.
This approach may enable the individual to take ownership over their transition story and to make sense of their life following TBI at a critical point in their recovery. A combined narrative and arts-based approach has potential as a culturally responsive rehabilitation tool for use with Indigenous Australians during the transition period following TBI.
Patients suffering from an out-of-hospital cardiac arrest (OHCA) associated with an initial shockable rhythm have a better prognosis than their counterparts. The implications of recurrent or refractory malignant arrhythmia in such context remain unclear. The objective of this study is to evaluate the association between the number of prehospital shocks delivered and survival to hospital discharge among patients in OHCA.
This cohort study included adult patients with an initial shockable rhythm over a 5-year period from a registry of OHCA in Montreal, Canada. The relationship between the number of prehospital shocks delivered and survival to discharge was described using dynamic probabilities. The association between the number of prehospital shocks delivered and survival to discharge was assessed using multivariable logistic regression.
A total of 1,788 patients (78% male with a mean age of 64 years) were included in this analysis, of whom 536 (30%) received treatments from an advanced care paramedic. A third of the cohort (583 patients, 33%) survived to hospital discharge. The probability of survival was highest with the first shock (33% [95% confidence interval 30%-35%]), but decreased to 8% (95% confidence interval 4%-13%) following nine shocks. A higher number of prehospital shocks was independently associated with lower odds of survival (adjusted odds ratio=0.88 [95% confidence interval 0.85-0.92], p < 0.001).
Survival remains possible even after a high number of shocks for patients suffering from an OHCA with an initial shockable rhythm. However, requiring more shocks is independently associated with worse survival.
Every nuclear weapons program for decades has relied extensively on illicit imports of nuclear-related technologies. This book offers the most detailed public account of how states procure what they need to build nuclear weapons, what is currently being done to stop them, and how global efforts to prevent such trade could be strengthened. While illicit nuclear trade can never be stopped completely, effective steps to block illicit purchases of nuclear technology have sometimes succeeded in slowing nuclear weapons programs and increasing their costs, giving diplomacy more chance to work. Hence, this book argues, preventing illicit transfers wherever possible is a key element of an effective global non-proliferation strategy.
Three different types of bivalent influenza virus vaccine, a whole virus, an aqueous-surface-antigen vaccine and an adsorbed-surface-antigen vaccine were tested at three dosage levels in volunteers primed with respect to only one of the haemagglutinin antigens present in the vaccines.
The local and systemic reactions to all three vaccine types were mild in nature and, following first immunization, the aqueous-surface-antigen vaccine was the least reactogenic. The serum haemagglutination-inhibiting antibody response to the A/Victoria/75 component of the vaccines, to which the volunteer population was primed, was greatest following immunization with the aqueous-surface-antigen vaccine; the greatest antibody response to the A/New Jersey/76 component of the vaccines was observed following immunization with whole virus vaccine.
We report on our ongoing imaging efforts to detect brown dwarfs orbiting solar-type stars and other brown dwarfs. We study the properties of brown dwarf companions as a function of primary mass. Our results indicate that the frequency of brown dwarf companions around solar-type stars for separations larger than about 40 AU is non-negligible. The frequency of brown dwarf binaries is about 20%. There is a dearth of brown dwarf binaries with separations larger than ∼20 AU. We propose that brown dwarf systems are a scaled down version of stellar systems, which probably form via triggered collapse of small molecular cores.
We present the results of a search for low-mass companions around a sample of young, solar-analog stars using the Hōkūpa'a adaptive optics instrument mounted on the Gemini North 8 m telescope. Out of 31 stars observed, one binary brown dwarf system was found as a companion to the star HD 130948 (HIP 72567), as confirmed by proper motion and near-IR spectra. Orbital motion between the two brown dwarfs was measured, but our 14 month time baseline is inadequate to accurately measure the system's dynamical mass. Upcoming spectroscopic observations of the brown dwarfs will measure their lithium absorption lines to provide a more accurate age estimate of the system. The eventual dynamical mass determination coupled with the age determination will provide a valuable check of brown dwarf evolutionary models.
The effect of mild head injury on event-related potential (ERP)
correlates of Stroop task performance was explored with the
aim of further elucidating the basis of processing impairments
after mild head injury. Computer- and card-based Stroop tasks
were employed to assess attention function. A sequence of
incongruent color words were presented followed by a sequence
of congruent color words (printed in congruent colors). Control
performance was equivalent on computer- and card-based versions
of the incongruent task and faster on the congruent card task
than the preceding congruent computer task. The mild head injury
group were as fast as controls on the computer-based task but
made more errors. However, they were relatively slower on both
the congruent and incongruent parts of the card-based task and
made more errors in the incongruent task. ERP correlates of
computer-based Stroop task performance suggested a greater
allocation of attention resources in the incongruent condition
in both groups in the form of relatively greater negativity
in the latency range 350 to 450 ms with a distribution consistent
with the activation of the anterior cingulate gyrus. In addition
the mild head injured group showed relatively greater enhancement
than the control group in this latency range in both congruent
and incongruent conditions. There was, however no evidence of
reduced amplitude P1, N1, N2, or P3b deflections. Trails, digit
symbol, digit span and auditory verbal learning tests (AVLT)
were also administered. Mild head injured participants were
impaired only on the AVLT. The finding of greater ERP negativity
in the mild head injured group is consistent with greater
allocation of attention resources to achieve equivalent performance
in the computer-based Stroop task. (JINS, 2002,
The CV PQ Gem is thought by many to be the first truly ‘Intermediate’ Polar in that it displays characteristics typical of the synchronous and high magnetic field strength (B ~10–230MG) AM Her systems as well as those of the asynchronous (and much weaker magnetic field strength) Intermediate Polar systems. Here we present the results of quasi-simultaneous optical photopolarimetric and EUVE observations.
The conditions leading to thermal runaway in metal oxide varistors are discussed in terms of its power dissipation. An equivalent circuit is used to rationalize the similarities and differences between the DC and 60 Hz ac behavior.
