    Activity and passivity: class and gender in the case of the artificial hand

    This article analyzes the tension between the active, present body and the absent, passive body in this medical case study, presented by doctor and prosthetist Henry Robert Heather Bigg in his 1885 book Artificial Limbs and the Amputations which Afford the Most Appropriate Stumps in Civil and Military Surgery. I reproduce Bigg's account in its entirety because, to date, Artificial Limbs has not been digitised, although it is held at around a dozen academic libraries in the UK and USA respectively. Bringing attention to and providing a close reading of a source not previously discussed academically sheds new light on the way the disabled body was read by medical professionals in the second half of the nineteenth century. In addition, I consider Bigg's narrative rendering of this unique case study alongside several contemporary sources, including memoirs, novels, short stories, and journal articles. In doing so, I identify how assumptions made by Bigg about the (disabled, female, privileged) hand mirror and echo those in the wider cultural sphere. The sensing hand is an instrument of will, and the creation of such a prosthesis troubles the dynamics of active and passive, touching and touched that Pamela K. Gilbert has identified as crucial to nineteenth-century discourses surrounding the hand. By designing and making this prosthesis, Bigg exerts his professional and masculine agency to make the woman's body assume the position of something beheld rather than embodied

    Insights into implementation planning for point-of-care testing to guide treatment of chronic obstructive pulmonary disease exacerbation: a mixed methods feasibility study

    The purpose of this mixed methods feasibility study was to gain insights into unmet clinical needs, stakeholder preferences and potential barriers and enablers to adoption for planning the implementation of point-of-care testing for earlier detection and guided treatment of chronic obstructive pulmonary disease (COPD) acute exacerbation in the NHS in England. Exacerbations of COPD cause considerable mortality and morbidity. Earlier identification of exacerbations and guided treatment would lead to reduced exacerbation duration, reduced hospitalizations and mortality, improve health-related quality of life, reduce unnecessary treatments (including inappropriate antibiotic prescribing) which could save the NHS over £400 per patient. During the early stages of product design, we took a multi-disciplinary approach to evidence generation, gaining insights from key stakeholders to test the product concept and inform evidence-based implementation planning. Primary data was collected from 11 health care and service professionals involved in the management of acute COPD exacerbations. Overall, participants agreed that by earlier differentiation of acute exacerbation from stable COPD, patients could be started on appropriate treatment. To implement point-of-care testing into clinical practice, evidence is required to demonstrate the accuracy of differentiating between exacerbation etiologies and to provide information on the beneficial impact to the system in terms of optimized management, reduced long-term side effects, admission avoidance, and cost-effectiveness. This research provides an evidence base for future implementation planning of point-of-care testing for earlier detection and guided treatment of COPD acute exacerbation. Moreover, the technology developers can decide whether to refine the product design and value proposition thereby de-risking product development

    ObjectivesThe aim of this study was to develop a comprehensive economic evaluation of the integrated cognitive assessment (ICA) tool compared with standard cognitive tests when used for dementia screening in primary care and for initial patient triage in memory clinics.MethodsICA was compared with standard of care comprising a mixture of cognitive assessment tools over a lifetime horizon and employing the UK health and social care perspective. The model combined a decision tree to capture the initial outcomes of the cognitive testing with a Markov structure that estimated long-term outcomes of people with dementia. Quality of life outcomes were quantified using quality-adjusted life years (QALYs), and the economic benefits were assessed using net monetary benefit (NMB). Both costs and QALYs were discounted at 3.5% per annum and cost-effectiveness was assessed using a threshold of £20,000 per QALY gained.ResultsICA dominated standard cognitive assessment tools in both the primary care and memory clinic settings. Introduction of the ICA tool was estimated to result in a lifetime cost saving of approximately £123 and £226 per person in primary care and memory clinics, respectively. QALY gains associated with early diagnosis were modest (0.0016 in primary care and 0.0027 in memory clinic). The net monetary benefit (NMB) of ICA introduction was estimated at £154 in primary care and £281 in the memory clinic settings.ConclusionIntroduction of ICA as a tool to screen primary care patients for dementia and perform initial triage in memory clinics could be cost saving to the UK public health and social care payer

    Identification of intermediates of in vivo trichloroethylene oxidation by the membrane-associated methane monooxygenase

    The rate and products of trichloroethylene (TCE) oxidation by Methylomicrobium album BG8 expressing membrane-associated methane monooxygenase (pMMO) were determined using 14 C radiotracer techniques. [ 14 C]TCE was degraded at a rate of 1.24 nmol (min mg protein) −1 with the initial production of glyoxylate and then formate. Radiolabeled CO 2 was also found after incubating M. album BG8 for 5 h with [ 14 C]TCE. Experiments with purified pMMO from Methylococcus capsulatus Bath showed that TCE could be mineralized to CO 2 by pMMO. Oxygen uptake studies verified that M. album BG8 could oxidize glyoxylate and that pMMO was responsible for the oxidation based on acetylene inactivation studies. Here we propose a pathway of TCE oxidation by pMMO-expressing cells in which TCE is first converted to TCE-epoxide. The epoxide then spontaneously undergoes HCl elimination to form glyoxylate which can be further oxidized by pMMO to formate and CO 2 .Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/74667/1/j.1574-6968.2000.tb09090.x.pd
