Bentham, Not Epicurus: The Relevance of Pleasure to Studies of Drug-Involved Pain

There is a disproportionate focus on pain over pleasure in policy-relevant research on drugs. This is unfortunate because theories of and findings on drug-involved pleasure can be used to inform knowledge of drug-involved pain. The cross-fertilization of theories and findings is bolstered by the availability of a conceptual framework that links drug-involved pain and pleasure in a comprehensive, powerful, simple, and instrumental manner. This article proposes such a framework. It consists of four types of drug-involved pain and pleasure: drug-specific corporal; drug-related corporal; economic; and, social. This quaternary scheme is illustrated with findings from four literatures, namely those on methamphetamine use; alcohol-related sexual contact among college students; resource transfer among drug users and dealers; and, relational and communal issues related to drugs. The article concludes with implications for the field

Making drug harms: Punishments for drugs offenders who pose risks to children

Images of children are routinely used in discourses on drugs, offering a compelling rationale for adopting particular policy positions or legislative reforms. However, the importance of childhood to the constitution of drug harms, and the punishment and subjectification of drug users and offenders, have rarely been the subject of enquiry, whether within drug and alcohol studies, criminology or legal studies. Scholarship on criminal sentencing in England and Wales is also relatively sparse, and has been dominated by analyses of the ‘legal-rational’ logic of particular provisions or reforms. This paper, which relies on the premise that drugs and their effects are constituted through discourse, and are thus contingent, variable and unstable, identifies the ‘collateral realities’ (Law, 2011) that are enacted during legislative and judicial attempts to stabilize the harms caused by drugs to children and communities

Lay beliefs of TB and TB/HIV co-infection in Addis Ababa, Ethiopia: a qualitative study

<p>Abstract</p> <p>Background</p> <p>Knowledge about lay beliefs of etiology, transmission and treatment of TB, and lay perceptions of the relationship between TB and HIV is important for understanding patients' health seeking behavior and adherence to treatment. We conducted a study to explore lay beliefs about TB and TB/HIV co-infection in Addis Ababa, Ethiopia.</p> <p>Findings</p> <p>We conducted a qualitative study using in-depth interviews with 15 TB/HIV co-infected patients and 9 health professionals and focus group discussions with 14 co-infected patients in Addis-Ababa, Ethiopia. We found that a predominant lay belief was that TB was caused by exposure to cold. Excessive sun exposure, exposure to mud, smoking, alcohol, khat and inadequate food intake were also reported as causes for TB. Such beliefs initially led to self-treatment. The majority of patients were aware of an association between TB and HIV. Some reported that TB could transform into HIV, while others said that the body could be weakened by HIV and become more susceptible to illnesses such as TB. Some patients classified TB as either HIV-related or non-HIV-related, and weight loss was a hallmark for HIV-related TB. The majority of patients believed that people in the community knew that there was an association between TB and HIV, and some feared that this would predispose them to HIV-related stigma.</p> <p>Conclusion</p> <p>There is a need for culturally sensitive information and educational efforts to address misperceptions about TB and HIV. Health professionals should provide information about causes and treatment of TB and HIV to co-infected patients.</p

The Role of Calcineurin/NFAT in SFRP2 Induced Angiogenesis—A Rationale for Breast Cancer Treatment with the Calcineurin Inhibitor Tacrolimus

Tacrolimus (FK506) is an immunosuppressive drug that binds to the immunophilin FKBPB12. The FK506-FKBP12 complex associates with calcineurin and inhibits its phosphatase activity, resulting in inhibition of nuclear translocation of nuclear factor of activated T-cells (NFAT). There is increasing data supporting a critical role of NFAT in mediating angiogenic responses stimulated by both vascular endothelial growth factor (VEGF) and a novel angiogenesis factor, secreted frizzled-related protein 2 (SFRP2). Since both VEGF and SFRP2 are expressed in breast carcinomas, we hypothesized that tacrolimus would inhibit breast carcinoma growth. Using IHC (IHC) with antibodies to FKBP12 on breast carcinomas we found that FKBP12 localizes to breast tumor vasculature. Treatment of MMTV-neu transgenic mice with tacrolimus (3 mg/kg i.p. daily) (n = 19) resulted in a 73% reduction in the growth rate for tacrolimus treated mice compared to control (n = 15), p = 0.003; which was associated with an 82% reduction in tumor microvascular density (p<0.001) by IHC. Tacrolimus (1 µM) inhibited SFRP2 induced endothelial tube formation by 71% (p = 0.005) and inhibited VEGF induced endothelial tube formation by 67% (p = 0.004). To show that NFATc3 is required for SFRP2 stimulated angiogenesis, NFATc3 was silenced with shRNA in endothelial cells. Sham transfected cells responded to SFRP2 stimulation in a tube formation assay with an increase in the number of branch points (p<0.003), however, cells transfected with shRNA to NFATc3 showed no increase in tube formation in response to SFRP2. This demonstrates that NFATc3 is required for SFRP2 induced tube formation, and tacrolimus inhibits angiogenesis in vitro and breast carcinoma growth in vivo. This provides a rationale for examining the therapeutic potential of tacrolimus at inhibiting breast carcinoma growth in humans

Dangerous drugs, dangerous mothers: Gender, responsibility and the problematisation of parental substance use

If, as many would have it, the ‘drugs problem’ is among the more perilous and uncompromising challenges of our times, parental substance misuse represents one of its most insidious expressions. The past 15 years has seen the ‘hidden harms’ experienced by the children of drug users emerge as a principal concern for national policy actors and local service provision. However, there has been relatively little critique of the assumptions and epistemological foundations underscoring this policy shift, or of the preoccupation with the ‘family’ in drug policy in general. Through examination of seminal policy documents relating to parental substance misuse, and using Carol Bacchi’s ‘What’s the Problem Represented to Be?’ (WPR) approach, this article attends more closely to the formulation of parental drug use as a significant policy problem, and to the family as a principal site for the constitution of drug harms

An Uncertain Dominion: Irish Psychiatry, Methadone, and the Treatment of Opiate Abuse

This paper investigates some productive ambiguities around the medical administration of methadone in the Republic of Ireland. The tensions surrounding methadone maintenance therapy (MMT) are outlined, as well as the sociohistorical context in which a serious heroin addiction problem in Ireland developed. Irish psychiatry intervened in this situation, during a time of institutional change, debates concerning the nature of addiction, moral panics concerning heroin addiction in Irish society and the recent boom in the Irish economy, known popularly as the Celtic Tiger. A particular history of this sort illuminates how technologies like MMT become cosmopolitan, settling into, while changing, local contexts

A Thousand Contradictory Ways: Addiction, Neuroscience, and Expert Autobiography

Neuroscientific accounts of addiction are increasingly influential in health and medical circles. At the same time a diverse, if equally scientifically focused, opposition to addiction neuroscience is emerging. In this struggle over the merits of addiction neuroscience are elements of a uniquely 21st-century public engagement with science. No longer trusted by the public as the unerring source of objective knowledge about the world, science is, at least in some contexts, increasingly treated as just one voice among many. Observing the difficulties this loss of faith in science poses for effective action on pressing issues such as climate change, philosopher Bruno Latour develops a different (ecological) approach to scientific knowledge, one that for the first time allows scientists (and other “moderns”) to understand it for what it really is and locate it “diplomatically” alongside other modes of knowing. In this article, I ask whether a similar innovation is needed to allow more effective understanding of addiction. I explore this question by analyzing two recent, widely discussed, popular books (Marc Lewis’s Memoirs of an Addicted Brain: A Neuroscientist Examines His Former Life on Drugs, 2011 and Carl Hart’s High Price: A Neuroscientist’s Journey of Self-discovery that Challenges Everything You Think You Know About Drugs and Society, 2013) as well as reviews of these books. Written by neuroscientists, and drawing heavily on personal memoir to illustrate and ratify their competing views on drugs and addiction, both books crystallize contemporary dilemmas about science, empiricism, and the nature of evidence and truth. How are we to understand their mix of “scientific fact” and individual self-observation, what does this mix suggest about scientific knowledge, and what are its implications for dominant notions of “evidence-based” drug policy and treatment? I argue that these books both trouble and reinforce our taken-for-granted distinctions between science and personal stories, between objectivity and subjectivity, and note the lost opportunities the books represent for a more searching and productive (Latour might say “ecological”) engagement with science

Intoxicants and the invention of 'consumption'

In 1600 the word ‘consumption’ was a term of medical pathology describing the ‘wasting, petrification of things’. By 1700 it was also a term of economic discourse: ‘In commodities, the value rises as its quantity is less and vent greater, which depends upon it being preferred in its consumption’. The article traces the emergence of this key category of economic analysis to debates over the economy in the 1620s and subsequent disputes over the excise tax, showing how ‘consumption’ was an early term in the developing lexicon of political economy. In so doing the article demonstrates the important role of ‘intoxicants’ – i.e. addictive and intoxicating commodities like alcohols and tobaccos – in shaping these early meanings and uses of ‘consumption’. It outlines the discursive importance of intoxicants, both as the foci for discussions of ‘superfluous’ and ‘necessary’ consumption and the target of legislation on consumption. And it argues that while these discussions had an ideological dimension, or dimensions, they were also responses to material increases in the volume and diversity of intoxicants in early seventeenth-century England. By way of conclusion the article suggests the significance of the Low Countries as a point of reference for English writers, as well as a more capacious and semantically sensitive approach to changes in early-modern consumption practices

Why healthcare workers are sick of TB

Dr Thato Mosidi never expected to be diagnosed with tuberculosis (TB), despite widely prevalent exposure and very limited infection control measures. The life-threatening diagnosis of primary extensively drug-resistant TB (XDR-TB) came as an even greater shock. The inconvenient truth is that, rather than being protected, Dr Mosidi and thousands of her healthcare colleagues are at an increased risk of TB and especially drug-resistant TB. In this viewpoint paper we debunk the widely held false belief that healthcare workers are somehow immune to TB disease (TB-proof) and explore some of the key factors contributing to the pervasive stigmatization and subsequent non-disclosure of occupational TB. Our front-line workers are some of the first to suffer the consequences of a progressively more resistant and fatal TB epidemic, and urgent interventions are needed to ensure the safety and continued availability of these precious healthcare resources. These include the rapid development and scale-up of improved diagnostic and treatment options, strengthened infection control measures, and focused interventions to tackle stigma and discrimination in all its forms. We call our colleagues to action to protect themselves and those they care for
