Transdermal fentanyl for the treatment of pain caused by osteoarthritis of the knee or hip: an open, multicentre study

BACKGROUND: This study was designed to evaluate the utility of transdermal fentanyl (TDF, Durogesic(®)) for the treatment of pain due to osteoarthritis (OA) of the knee or hip, which was not adequately controlled by non-opioid analgesics or weak opioids. The second part of the trial, investigating TDF in patients with rheumatoid arthritis (RA) is reported separately. METHODS: Current analgesia was optimised during a 1-week run-in. Patients then received 28 days treatment with TDF starting at 25 μg/hr, with the option to increase the dose until adequate pain control was achieved. Metoclopramide was taken during the first week and then as needed. RESULTS: Of the 159 patients recruited, 75 with OA knee and 44 with OA hip completed the treatment phase, 30 knee and 18 hip patients entered the one-week taper-off phase. The most frequently used maximum dose of TDF was 25 μg/hr. The number of patients with adequate pain control increased during the run-in period from 4% to 27%, and further increased during TDF treatment to 88% on day 28. From baseline to endpoint, there were significant reductions in pain (p < 0.001) and improvements in functioning (p < 0.001) and physical (p < 0.001) and mental (p < 0.05) health. Scores for 'pain right now' decreased significantly within 24 hours of starting TDF treatment. TDF was assessed favourably and 84% of patients would recommend it for OA-related pain. Nausea and vomiting were the most common adverse events (reported by 32% and 26% of patients respectively), despite prophylaxis with metoclopramide, which showed limited efficacy in this setting. CONCLUSION: TDF significantly increased pain control, and improved functioning and quality of life. Metoclopramide appeared to be of limited value in preventing nausea and vomiting; more effective anti-emetic treatment may enable more people to benefit from strong opioids such as TDF. This study suggests that four weeks is a reasonable period to test the benefit of adding TDF to improve pain control in OA patients and that discontinuing therapy in cases of limited benefit creates no major obstacles

Rituals of World Politics: On (Visual) Practices Disordering Things

Rituals are customarily muted into predictable and boring routines aimed to stabilise social orders and limit conflict. As a result, their magic lure recedes into the background, and the unexpected, disruptive and disordered elements are downplayed. Our collaborative contribution counters this move by foregrounding rituals of world politics as social practices with notable disordering effects. The collective discussion recovers the disruptive work of a range of rituals designed to sustain the sovereign exercise of violence and war. We do so through engaging a series of ‘world pictures' (Mitchell 2007). We show the worlding enacted in rituals such as colonial treaty-making, state commemoration, military/service dog training, cyber-security podcasts,algorithmically generated maps, the visit of Prince Harry to a joint NATO exercise and border ceremonies in India, respectively. We do so highlighting rituals’ immanent potential for disruption of existing orders, the fissures, failures and unforeseen repercussions. Reappraising the disordering role of ritual practices sheds light on the place of rituals in rearticulating the boundaries of the political. It emphasises the role of rituals in generating dissensus and re-divisions of the sensible rather than in imposing a consensus by policing the boundaries of the political, as Rancière might phrase it. Our images are essential to the account. They help disinterring the fundamentals and ambiguities of the current worldings of security, capturing the affective atmosphere of rituals

Tracking Antigen-Specific T-Cells during Clinical Tolerance Induction in Humans

Allergen immunotherapy presents an opportunity to define mechanisms of induction of clinical tolerance in humans. Significant progress has been made in our understanding of changes in T cell responses during immunotherapy, but existing work has largely been based on functional T cell assays. HLA-peptide-tetrameric complexes allow the tracking of antigen-specific T-cell populations based on the presence of specific T-cell receptors and when combined with functional assays allow a closer assessment of the potential roles of T-cell anergy and clonotype evolution. We sought to develop tools to facilitate tracking of antigen-specific T-cell populations during wasp-venom immunotherapy in people with wasp-venom allergy. We first defined dominant immunogenic regions within Ves v 5, a constituent of wasp venom that is known to represent a target antigen for T-cells. We next identified HLA-DRB1*1501 restricted epitopes and used HLA class II tetrameric complexes alongside cytokine responses to Ves v 5 to track T-cell responses during immunotherapy. In contrast to previous reports, we show that there was a significant initial induction of IL-4 producing antigen-specific T-cells within the first 3–5 weeks of immunotherapy which was followed by reduction of circulating effector antigen-specific T-cells despite escalation of wasp-venom dosage. However, there was sustained induction of IL-10-producing and FOXP3 positive antigen-specific T cells. We observed that these IL-10 producing cells could share a common precursor with IL-4-producing T cells specific for the same epitope. Clinical tolerance induction in humans is associated with dynamic changes in frequencies of antigen-specific T-cells, with a marked loss of IL-4-producing T-cells and the acquisition of IL-10-producing and FOXP3-positive antigen-specific CD4+ T-cells that can derive from a common shared precursor to pre-treatment effector T-cells. The development of new approaches to track antigen specific T-cell responses during immunotherapy can provide novel insights into mechanisms of tolerance induction in humans and identify new potential treatment targets

Duty to God/my Dharma/Allah/Waheguru: diverse youthful religiosities and the politics and performance of informal worship

This article was published in the journal, Social and Cultural Geography [© Taylor & Francis] and the definitive version is available at: http://dx.doi.org/10.1080/14649365.2012.698749This paper draws on a case study of the Scout Movement in the UK to explore the everyday, informal expressions of ‘worship’ by young people that occur outside of ‘designated’ religious spaces and the politics of these performances over time. In analysing the explicit geographies of how young people in UK scouting perform their ‘duty to God’ (or Dharma and so forth), it is argued that a more expanded concept of everyday and embodied worship is needed. This paper also attends to recent calls for more critical historical geographies of religion, drawing on archival data to examine the organisation's relationship with religion over time and in doing so contributes new insights into the production of youthful religiosities and re-thinking their designated domains

Commercial sexual practices before and after legalization in Australia

The nature of sex work changes over time for many reasons. In recent decades around the world, there has been movement toward legalization and control of sex economies. Studies of the possible impact of legalization mainly have focused on sexually transmitted infections and violence, with little attention to change in the diversity of sexual services provided. This study examined the practices of sex workers before and after legalization of prostitution. Cross-sectional surveys of comparable samples of female sex workers were conducted in 1991 (N = 200, aged 16–46 years) and 2003 (N = 247, aged 18–57 years) in Queensland, Australia, spanning a period of major change in regulation of the local industry. In 2003, male clients at brothels and private sole operators (N = 161; aged 19–72 years) were also interviewed. Over time, there was a clear increase in the provision of “exotic” sexual services, including bondage and discipline, submission, fantasy, use of sex toys, golden showers, fisting, and lesbian double acts, while “traditional” services mostly remained at similar levels (with substantial decrease in oral sex without a condom). Based on comparisons of self-reports of clients and workers, the demand for anal intercourse, anal play, and urination during sex apparently exceeded supply, especially in licensed brothels. Within this population, legalization of sex work coincided with a substantial increase in diversity of services, but it appears that in the regulated working environments, clients who prefer high risk practices might not dictate what is available to them
