BHPR research: qualitative1. Complex reasoning determines patients' perception of outcome following foot surgery in rheumatoid arhtritis

Background: Foot surgery is common in patients with RA but research into surgical outcomes is limited and conceptually flawed as current outcome measures lack face validity: to date no one has asked patients what is important to them. This study aimed to determine which factors are important to patients when evaluating the success of foot surgery in RA Methods: Semi structured interviews of RA patients who had undergone foot surgery were conducted and transcribed verbatim. Thematic analysis of interviews was conducted to explore issues that were important to patients. Results: 11 RA patients (9 ♂, mean age 59, dis dur = 22yrs, mean of 3 yrs post op) with mixed experiences of foot surgery were interviewed. Patients interpreted outcome in respect to a multitude of factors, frequently positive change in one aspect contrasted with negative opinions about another. Overall, four major themes emerged. Function: Functional ability & participation in valued activities were very important to patients. Walking ability was a key concern but patients interpreted levels of activity in light of other aspects of their disease, reflecting on change in functional ability more than overall level. Positive feelings of improved mobility were often moderated by negative self perception ("I mean, I still walk like a waddling duck”). Appearance: Appearance was important to almost all patients but perhaps the most complex theme of all. Physical appearance, foot shape, and footwear were closely interlinked, yet patients saw these as distinct separate concepts. Patients need to legitimize these feelings was clear and they frequently entered into a defensive repertoire ("it's not cosmetic surgery; it's something that's more important than that, you know?”). Clinician opinion: Surgeons' post operative evaluation of the procedure was very influential. The impact of this appraisal continued to affect patients' lasting impression irrespective of how the outcome compared to their initial goals ("when he'd done it ... he said that hasn't worked as good as he'd wanted to ... but the pain has gone”). Pain: Whilst pain was important to almost all patients, it appeared to be less important than the other themes. Pain was predominately raised when it influenced other themes, such as function; many still felt the need to legitimize their foot pain in order for health professionals to take it seriously ("in the end I went to my GP because it had happened a few times and I went to an orthopaedic surgeon who was quite dismissive of it, it was like what are you complaining about”). Conclusions: Patients interpret the outcome of foot surgery using a multitude of interrelated factors, particularly functional ability, appearance and surgeons' appraisal of the procedure. While pain was often noted, this appeared less important than other factors in the overall outcome of the surgery. Future research into foot surgery should incorporate the complexity of how patients determine their outcome Disclosure statement: All authors have declared no conflicts of interes

Cenozoic post-rift sedimentation off northwest Britain : recording the detritus of episodic uplift on a passive continental margin

The Cenozoic sedimentary basins on the Atlantic margin of NW Britain contain a remarkable record of tectonically influenced post-breakup sedimentation. We have mapped the distribution and quantified the solid grain volume of four unconformity-bound successions in the region: the Eocene (~6–8 × 104 km3), Oligocene (~2 × 104 km3), MioceneLower Pliocene (~4–5 × 104 km3) and Lower PlioceneHolocene (~4–5 × 104 km3) complementing previous work on the Paleocene succession. Approximately 80% of the total Cenozoic sediment volume on the Atlantic margin of NW Britain was deposited in Eocene and later times. The relative volumes of the Cenozoic succession do not support previous claims that the Paleocene was the main period of Cenozoic uplift and erosion of sediment source areas. Rather, the Cenozoic sedimentary basins on the Atlantic margin of NW Britain record the detritus of four major episodes of Cenozoic uplift of the British Isles (Paleocene, Eocene–Oligocene, Miocene and Pliocene–Pleistocene)

Multiple post-Caledonian exhumation epsiodes across Northwest Scotland revealed by apatite fission track analysis

The post-Caledonian exhumation history of NW Scotland is a controversial issue, with some studies advocating largely continual emergence whereas others suggest dominantly early Palaeogene plume-driven uplift. Apatite fission-track analysis (AFTA) for samples of Precambrian basement and Permian–Cretaceous sediments from onshore and offshore reveal multiple phases of post-Caledonian cooling: Triassic (beginning 245-225 Ma), Cretaceous (140-130 Ma; 110-90 Ma) and Cenozoic (65-60 Ma; 40-25 Ma; 15-10 Ma), all of which are interpreted at least in part as recording exhumation. Basement and sedimentary cover rocks display similar thermal histories, emphasising the regional nature of these episodes and implying that sedimentary outliers represent the remnants of previously more extensive sequences. Significant thicknesses of Jurassic rocks may once have covered NW Scotland. Paleocene palaeothermal effects are most pronounced in the vicinity of igneous centres, probably reflecting combined effects of heating by elevated heat flow, deeper burial and hydrothermal activity. Most of the region underwent kilometre-scale Neogene exhumation. Contrary to the common assumption of monotonic cooling and denudation histories, integration of geological evidence with AFTA data defines an episodic thermal history involving repeated cycles of burial and exhumation. We suggest that onshore passive margins and continental interiors may also best be characterised by similar histories
