Longitudinal study of informed consent in innovative therapy research: experience and provisional recommendations from a multicenter trial of intracerebral grafting.
BACKGROUND: There is an urgent need to assess and improve the consent process in clinical trials of innovative therapies for neurodegenerative disorders.
METHODS: We performed a longitudinal study of the consent of Huntington's disease patients during the Multicenter Fetal Cell Intracerebral Grafting Trial in Huntington's Disease (MIG-HD) in France and Belgium. Patients and their proxies completed a consent questionnaire at inclusion, before signing the consent form and after one year of follow-up, before randomization and transplantation. The questionnaire explored understanding of the protocol, satisfaction with the information delivered, reasons for participating in the trial and expectations regarding the transplant. Forty-six Huntington's disease patients and 27 proxies completed the questionnaire at inclusion, and 27 Huntington's disease patients and 16 proxies one year later.
RESULTS: The comprehension score was high and similar for Huntington's disease patients and proxies at inclusion (72.6% vs 77.8%; P > 0.1) but only decreased in HD patients after one year. The information satisfaction score was high (73.5% vs 66.5%; P > 0.1) and correlated with understanding in both patients and proxies. The motivation and expectation profiles were similar in patients and proxies and remained unchanged after one year.
CONCLUSIONS: Cognitively impaired patients with Huntington's disease were capable of consenting to participation in this trial. This consent procedure has presumably strengthened their understanding and should be proposed before signing the consent form in future gene or cell therapy trials for neurodegenerative disorders. Because of the potential cognitive decline, proxies should be designated as provisional surrogate decision-makers, even in competent patients
Paying for free delivery: dependent self-employment as a measure of precarity in parcel delivery
This article explores supply chain pressures in parcel delivery and how the drive to contain costs to ‘preserve value in motion’, including the costs of failed delivery, underpins contractual
differentiation. It focuses on owner-drivers and home couriers paid by delivery. It considers precarity through the lens of the labour process, while locating it within the supply chain, political economy and ‘instituted economic process’ that define it. Focus on the labour process shows how ‘self-employment’ is used to remove so-called ‘unproductive’ time from the remit of paid labour. Using Smith’s concept of double indeterminacy the article captures the dynamic relationship between those on standard and non-standard contracts and interdependency of effort power and mobility power. It exposes the apparent mobility and autonomy of dependent selfemployed drivers while suggesting that their presence, alongside the increased use of technology, reconfigures the work-effort bargain across contractual status
In, Against and Beyond Precarity: Work in Insecure Times
In this Foreword to the special issue ‘In, Against and Beyond Precarity’ the guest editors take stock of the existing literature on precarity, highlighting the strengths and limitations of using this concept as an analytical tool for examining the world of work. Concluding that the overstretched nature of concept has diluted its political effectiveness, the editors suggest instead a focus on precarization as a process, drawing from perspectives that focus on the objective conditions, as well as subjective and heterogeneous experiences and perceptions of insecure employment. Framed in this way, they present a summary of the contributions to the special issue spanning a range of countries and organizational contexts, identifying key drivers, patterns and forms of precarization. These are conceptualized as implicit, explicit, productive and citizenship precarization. These forms and patterns indicate the need to address precariousness in the realm of social reproduction and post-wage politics, while holding these in tension with conflicts at the point of production. Finally, the guest editors argue for a dramatic re-think of current forms of state and non-state social protections as responses to the precarization of work and employment across countries in both the Global ‘North’ and ‘South’

Ethical principles in machine learning and artificial intelligence: cases from the field and possible ways forward
Decision-making on numerous aspects of our daily lives is being outsourced to machine-learning algorithms and artificial intelligence (AI), motivated by speed and efficiency in the decision process. Machine learning (ML) approaches - one of the typologies of algorithms underpinning artificial intelligence - are typically developed as black boxes. The implication is that ML code scripts are rarely scrutinised; interpretability is usually sacrificed in favour of usability and effectiveness. Room for improvement in practices associated with programme development have also been flagged along other dimensions, including inter alia fairness, accuracy, accountability, and transparency. In this contribution, the production of guidelines and dedicated documents around these themes is discussed. The following applications of AI-driven decision making are outlined: a) Risk assessment in the criminal justice system, and b) autonomous vehicles, highlighting points of friction across ethical principles. Possible ways forward towards the implementation of governance on AI are finally examined

The meta-crisis of secular capitalism
The current global economic crisis concerns the way in which contemporary capitalism has turned to financialisation as a double cure for both a falling rate of profit and a deficiency of demand. Although this turning is by no means unprecedented, policies of financialisation have depressed demand (in part as a result of the long-term stagnation of average wages) while at the same time not proving adequate to restore profits and growth. This paper argues that the current crisis is less the ‘normal’ one that has to do with a constitutive need to balance growth of abstract wealth with demand for concrete commodities. Rather, it marks a meta-crisis of capitalism that is to do with the difficulties of sustaining abstract growth as such. This meta-crisis is the tendency at once to abstract from the real economy of productive activities and to reduce everything to its bare materiality. By contrast with a market economy that binds material value to symbolic meaning, a capitalist economy tends to separate matter from symbol and reduce materiality to calculable numbers representing ‘wealth’. Such a conception of wealth rests on the aggregation of abstract numbers that cuts out all the relational goods and the ‘commons’ on which shared prosperity depends

Dunno if you've any plans for the future: medical student indirect questioning in simulated oncology interviews
<p>Abstract</p> <p>Background</p> <p>This exploratory study investigated the motives of medical students (N = 63) for using indirect questions of the type <it>I don't know if </it>[you have already heard about chemotherapies], <it>I don't know how </it>[you are], or <it>I don't know what </it>[you do for a living] in simulated patient interviews during a communication skills course.</p> <p>Methods</p> <p><it>I don't know </it>questions (IDK-Qs) were observed during the initial evaluation of students' communication skills; they were systematically identified through video screening and subjected to a qualitative content and discourse analysis considering their context, their content, their intent and their effect on the simulated patients. To evaluate the specificity of medical students' IDK-Qs, the data were compared with a data set of oncologists (N = 31) conducting simulated patient interviews in the context of a Communication Skills Training (CST).</p> <p>Results</p> <p>During the interviews, 41.3% of the students asked 1-6 IDK-Qs. The IDK-Qs were attributed to three content categories: medical/treatment questions (N = 24); lifestyle/psychosocial questions (N = 18); and "inviting questions" questions (N = 11). Most of the IDK-Qs had an exploratory function (46/53), with simulated patients providing detailed responses or asking for more information (36/53). IDK-Qs were rare in the oncologist sample compared to the student sample (5 vs. 53 occurrences).</p> <p>Conclusions</p> <p>IDK-Qs showed a question design difference between medical students and oncologists in simulated patient interviews. Among other reasons for this difference, the possible function of IDK-Qs as a protective linguistic strategy and marker for psychological discomfort is discussed.</p
Towards homogenization of total body irradiation practices in pediatric patients across SIOPE affiliated centers. A survey by the SIOPE radiation oncology working group
BACKGROUND AND PURPOSE: To reduce relapse risk, Total Body Irradiation (TBI) is part of conditioning regimens for hematopoietic stem cell transplantation (HSCT) in pediatric acute leukemia. The study purpose was to evaluate clinical practices regarding TBI, such as fractionation, organ shielding and delivery techniques, among SIOPE affiliated radiotherapy centers. METHODS: An electronic survey was sent out to 233 SIOPE affiliated centers, containing 57 questions about clinical practice of TBI. Surveys could be answered anonymously. RESULTS: From over 25 countries, 82 responses were collected. For TBI-performing centers, 40/48 irradiated ≤10 pediatric patients annually (range: 1-2 to >25). Most indications concerned acute lymphoblastic leukemia (ALL) or acute myeloid leukemia (AML). Four different fractionation schedules were used, of which 12 Gy in 6 fractions was applied in 91% for ALL and 86% for AML. Dose reduction to the lungs, mostly to a mean dose of 8-10 Gy, was applied by 28/33 centers for ALL and 19/21 centers for AML, in contrast to much less applied dose reduction to the kidneys (7/33 ALL and 7/21 AML), thyroid (2/33 ALL and 2/21 AML), liver (4/33 ALL and 3/21 AML) and lenses (4/33 ALL and 4/21 AML). Conventional TBI techniques were used by 24/29 responding centers, while 5/29 used advanced optimized planning techniques. CONCLUSION: Across SIOPE, there is a high level of uniformity in fractionation and use of lung shielding. Practices vary regarding other organs-at-risk shielding and implementation of advanced techniques. A SIOPE radiotherapy working group will be established to define international guidelines for pediatric TBI
