Using the STarT Back Tool: does timing of stratification matter?
No full textIt is likely that individuals with nonspecific LBP (nsLBP) constitute a heterogenic group and targeting treatment appropriately to those most likely to respond is of major relevance. The STarT Back Tool (SBT) has been developed to stratify patients into risk groups to aid management choices. However, there is controversy over its generalisability and uncertainty as to the timing of use. This study investigated whether SBT categorisation early in a course of treatment would prove more prognostic than categorising patients at baseline. Seven hundred and forty nine patients over the age of 16 were recruited at 11 chiropractic clinics within the UK. The SBT was used to categorise these patients at presentation and 2 days following initial treatment with patient characteristics and condition specific markers also collected at baseline. The primary outcome was the Patient Global Impression of Change (PGIC) collected at 14, 30 and 90 days following the initial visit. In this population undergoing chiropractic care, patients had similar outcomes irrespective of their STarT back risk ranking. Multivariate prognostic models included only the post initial visit SBT as an independent predictor of favourable outcome for the medium risk group but only at 30 days. Follow up improvement was dominated by previous improvement in 30 and 90-day models. Over one third of patients swapped SBT risk groups in the 2 day period between initial stratification and post initial visit although there was little difference in eventual improvement at follow-up. Understanding the impact of timing of SBT stratification is indicated
Using the ICF and psychological models of behavior to predict mobility limitations
No full textAims to test the ability of a model that integrates the theory of planned behavior (TPB) into the International Classification of Functioning Disability and Health (ICF) to predict walking limitations in adults awaiting hip or knee replacement surgery. Study Design and Participants: Cross-sectional structural equation modeling study of activity limitations in 190 adults. Method: A postal questionnaire measuring the TPB, ICF and walking limitations. Results: The integrated model accounted for more variance in activity limitations (57%) than either the TPB or ICF alone. Control beliefs (TPB) significantly mediated the relationship between impairment (ICF) and activity limitations. Conclusions: The integrated model provides an interdisciplinary theoretical framework that identifies intervention targets to effect reductions in disability without the need for concomitant reductions in impairment
Comparison of thermal modeling, microstructural analysis, and Ti-in-quartz thermobarometry to constrain the thermal history of a cooling pluton during deformation in the Mount Abbot Quadrangle, CA
No full textGranitic plutons commonly preserve evidence for jointing, faulting, and ductile fabric
development during cooling. Constraining the spatial variation and temporal evolution of temperature
during this deformation could facilitate an integrated analysis of heterogeneous deformation over multiple
length-scales through time. Here, we constrain the evolving temperature of the Lake Edison granodiorite
within the Mount Abbot Quadrangle (central Sierra Nevada, CA) during late Cretaceous deformation by
combining microstructural analysis, titanium-in-quartz thermobarometry (TitaniQ), and thermal modeling.
Microstructural and TitaniQ analyses were applied to 12 samples collected throughout the pluton,
representative of either the penetrative ‘‘regional’’ fabric or the locally strong ‘‘fault-related’’ fabric.
Overprinting textures and mineral assemblages indicate the temperature decreased from 400–5008C to
<3508C during faulting. TitaniQ reveals consistently lower Ti concentrations for partially reset fault-related
fabrics (average: 1264 ppm) than for regional fabrics (average: 31612 ppm), suggesting fault-related
fabrics developed later, following a period of pluton cooling. Uncertainties, particularly in TiO2 activity,
significantly limit further quantitative thermal estimates using TitaniQ. In addition, we present a 1-D heat
conduction model that suggests average pluton temperature decreased from 5858C at 85 Ma to 3328C at 79
Ma, consistent with radiometric age data for the field. Integrated with the model results, microstructural
temperature constraints suggest faulting initiated by 83 Ma, when the temperature was nearly uniform
across the pluton. Thus, spatially heterogeneous deformation cannot be attributed to a persistent
temperature gradient, but may be related to regional structures that develop in cooling plutons.University of Delaware. Department of Geological Sciences

Remembering BC\u27s 1983 Solidarity Uprising — with David Spaner
No full textBio: David Spaner has worked as a feature writer, movie critic, reporter, and editor for numerous newspapers and magazines. David\u27s also been a cultural/political organizer (Yippie, manager of the punk band The Subhumans). He is the author of Dreaming in the Rain and Shoot It! Hollywood, Inc. and the Rising of Independent Film.In 2021, Spaner published a behind-the-scenes book about the Solidarity resistance movement, Solidarity: Canada\u27s Unknown Revolution of 1983 (Ronsdale 2021) documenting the event using intimate storytelling and melding cultural and rebel politics to provide insight into the conflicts that are still with us. It was the largest political protest in the province\u27s history and threatened to end in an all-out general strike.
