The evidence base for oxygen for chronic refractory breathlessness: issues, gaps, and a future work plan
Breathlessness or “shortness of breath”, medically termed dyspnoea, remains a devastating
problem for many people and those who care for them. As a treatment intervention,
administration of opioids to relieve breathlessness is an area where progress has been made
with the development of an evidence base. As evidence in support of opioids has
accumulated, so has our collective understanding about trial methodology, research
collaboration and infrastructure that is crucial to generate reliable research results for
palliative care clinical settings.
Analysis of achievements to date and what it takes to accomplish these studies provides
important insights into knowledge gaps needing further research as well as practical insight
into design of pharmacological and non-pharmacological intervention trials in breathlessness
and palliative care.
This paper presents current understanding of opioids for treating breathlessness, what is still
unknown as priorities for future research and highlights methodological issues for
consideration in planned studies.This research received no specific grant from any funding agency in the public, commercial,

Different formulations of 3He and 3H photodisintegration
Different momentum space Faddeev-like equations and their solutions for the
radiative pd-capture and the three-nucleon photodisintegration of 3He are
presented. Applications are based on the AV18 nucleon-nucleon and the Urbana IX
three nucleon forces. Meson exchange currents are included using the Siegert
theorem. A very good agreement has been found in all cases indicating the
reliability of the used numerical methods. Predictions for cross sections and
polarization observables in the pd-capture and the complete three nucleon
breakup of 3He at different incoming deuteron/photon energies are presented.Comment: 18 pages, 9 ps figure

Observation of the Charge Symmetry Breaking d + d -> 4He + pi0 Reaction Near Threshold
We report the first observation of the charge symmetry breaking d + d -> 4He
+ pi0 reaction near threshold at the Indiana University Cyclotron Facility.
Kinematic reconstruction permitted the separation of 4He + pi0 events from
double radiative capture 4He + gamma + gamma events. We measured total cross
sections for neutron pion production of 12.7 +- 2.2 pb at 228.5 MeV and 15.1 +-
3.1 pb at 231.8 MeV. The uncertainty is dominated by statistical errors.Comment: 7 pages, 2 figures, plain Te
Cross section and analyzing power of pol{p}p -> pn pi+ near threshold
The cross section and analyzing power of the pol{p}p -> pn pi+ reaction near
threshold are estimated in terms of data obtained from the pol{p}p -> d pi+ and
pp -> pp pi0 reactions. A simple final state interaction theory is developed
which depends weakly upon the form of the pion-production operator and includes
some Coulomb corrections. Within the uncertainties of the model and the input
data, the approach reproduces well the measured energy dependence of the total
cross section and the proton analyzing power at a fixed pion c.m. angle of
90deg, from threshold to T_p = 330 MeV. The variation of the differential cross
section with pion angle is also very encouraging.Comment: 20 pages, Latex including 4 eps figure
Isoscalar off-shell effects in threshold pion production from pd collisions
We test the presence of pion-nucleon isoscalar off-shell effects in the
reaction around the threshold region. We find that these
effects significantly modify the production cross section and that they may
provide the missing strength needed to reproduce the data at threshold.Comment: 6 pages, REVTeX, twocolumn, including 3 figures (Postscript), uses
