elastic scattering and reaction cross-section data at incident energies below, atop
and above the Δ-resonance are analyzed using the full Klein-Gordon equation using
an optical potential. Analytic forms of the potential are determined using the inverse
scattering theory in those cases where phase shift analyses were available. The
Coulomb effect is incorporated using Stricker’s prescription. Both elastic scattering
data and the reaction cross sections between 120 and 400 MeV are well reproduced.
Both real and imaginary parts of the potential are local. The potential points determined
by the inverse scattering theory in the interior region at 230 MeV clearly establish
that the real part is repulsive. This remains the case at higher incident energies.
The real part turns repulsive above the resonance, whereas the imaginary part reflects
the dominance of surface absorption, which is maximum near atop the Δ-resonance
and then falling off at higher energies.
Introduction: Rapid and
appropriate family risk assessment and triage of patients are essential for
patients presenting to a symptomatic breast unit and international criteria for
review are well established. Family History Risk Assessment Software (FaHRAS)
is a computerized program, involving different modalities of risk assessment,
which is available but has not been widely assessed. Aims: This study evaluated
the FaHRAS software scoring of family history risk. Its analysis was compared
to multi-tool family history risk assessment models in a cohort of 353 patients
on a historic family history waiting list. Methods: A recent published pilot
study assessed and categorized family history risk in 353 patients on a
historic family history waiting list, according to international guidelines
including NICE criteria, Gail and IBIS risk estimates. The current study
involved a reassessment of all 353 patients using the FaHRAS software program
to determine its accuracy and ease of use. Patient demographics and time
required to perform the analysis were documented. Results: FaHRAS identified 73
(20.7%) patients had an IBIS family history score of 17% or greater and 89
(25.2%) patients met the NICE guidelines criteria for management beyond primary
care. In the previous study, this was 79 (22.4%) and 112 (31.7%) respectively.
Using the largest denominator (NICE guidelines), 264/353 (74.8%) patients could
be discharged to primary care using FaHRAS. Using this largest denominator,
FaHRAS also identified a total of 28 (7.9%) patients requiring referral to
tertiary care while the previous study identified 3 (0.8%). Conclusion: This is
one of the first studies to validate FaHRAS, which is accurate and easy to use.
FaHRAS system can enable clinicians to become more efficient gatekeepers to
