Consent processes for clinical trials involving HIV prevention research have generated considerable debate globally over the past three decades. HIV cure/eradication research is scientifically more complex and consequently, consent processes for clinical trials in this field are likely to pose a significant challenge. Given that research efforts are now moving toward HIV eradication, stakeholder engagement to inform appropriate ethics oversight of such research is timely. This study sought to establish the perspectives of a wide range of stakeholders in HIV treatment (...) and research to inform consent processes for cure research. In total, 68 South African stakeholders participated in two qualitative research modalities. In-depth interviews were conducted with a purposive sample of 42 individuals - audiotaped with consent. Twenty-six stakeholders participated in three focus group discussions. Thematic analysis of transcribed IDIs and FGDs was conducted. The majority of respondents indicated that there could be unique challenges in HIV cure research requiring special attention. In particular, given the complexity of cure science, translation of concepts into lay language would be critical for potential participants to adequately appreciate risks and benefits in early phase research with experimental interventions. Furthermore, to aid understanding of risks and benefits against a background of desperation for a cure, specially trained facilitators would be required to assist with a psychological assessment prior to consent to avoid curative misconceptions. Long-term participant engagement to assess durability of a cure would mean that the consent process would be prolonged, necessitating annual re-consent. Building trust to maintain such long-term relationships would be critical to retain study participants. Unique consent requirements for cure research in South Africa would include significant efforts to maximise understanding of trial procedures, risks and the need for long-term follow-up. However, the psychological dimension of cure must not be underestimated. Beyond an understanding of cure science, the emotional impact of HIV cure advances the discourse from cure to healing. Consequently, the consent process for cure research would need to be enhanced to include psychological support and counselling. This has several important implications for research ethics review requirements for consent in HIV cure research. (shrink)

A simple numerical procedure is presented for the problem of estimating the parameters of models for the distribution of eggs oviposited in a host. The modelling is extended to incorporate both host density and time dependence to produce a remarkably parsimonious structure with only seven parameters to describe a data set of over 3,000 observations. This is further refined using a mixed model to accommodate several large outliers. Both models show that the level of superparasitism declines with increasing host density, (...) and the rate declines over time. It is proposed that the differing behaviours represented by the mixed model may reflect a balance between behavioural strategies of different selective benefit. (shrink)

BackgroundThe ARRIVE (Animal Research: Reporting of In Vivo Experiments) guidelines are widely endorsed but compliance is limited. We sought to determine whether journal-requested completion of an ARRIVE checklist improves full compliance with the guidelines.MethodsIn a randomised controlled trial, manuscripts reporting in vivo animal research submitted to PLOS ONE (March–June 2015) were randomly allocated to either requested completion of an ARRIVE checklist or current standard practice. Authors, academic editors, and peer reviewers were blinded to group allocation. Trained reviewers performed outcome adjudication (...) in duplicate by assessing manuscripts against an operationalised version of the ARRIVE guidelines that consists 108 items. Our primary outcome was the between-group differences in the proportion of manuscripts meeting all ARRIVE guideline checklist subitems.ResultsWe randomised 1689 manuscripts (control: n = 844, intervention: n = 845), of which 1269 were sent for peer review and 762 (control: n = 340; intervention: n = 332) accepted for publication. No manuscript in either group achieved full compliance with the ARRIVE checklist. Details of animal husbandry (ARRIVE subitem 9b) was the only subitem to show improvements in reporting, with the proportion of compliant manuscripts rising from 52.1 to 74.1% (X2 = 34.0, df = 1, p = 2.1 × 10−7) in the control and intervention groups, respectively.ConclusionsThese results suggest that altering the editorial process to include requests for a completed ARRIVE checklist is not enough to improve compliance with the ARRIVE guidelines. Other approaches, such as more stringent editorial policies or a targeted approach on key quality items, may promote improvements in reporting. (shrink)

Military metaphors are pervasive in biomedicine, including HIV research. Rooted in the mind set that regards pathogens as enemies to be defeated, terms such as “shock and kill” have become widely accepted idioms within HIV cure research. Such language and symbolism must be critically examined as they may be especially problematic when used to express scientific ideas within emerging health-related fields. In this article, philosophical analysis and an interdisciplinary literature review utilizing key texts from sociology, anthropology, history, and Chinese and (...) African studies were conducted to investigate the current proliferation of military metaphors. We found the use of these metaphors to be ironic, unfortunate, and unnecessary. To overcome military metaphors we propose to give them less aggressive meanings, and/or replace them with more peaceful metaphors. Building on previous authors' work, we argue for the increased use of “journey” metaphors as meaningful, cross-culturally app... (shrink)

The aim of the article is threefold: to argue and motivate that unnecessary surgery is a worldwide phenomenon, that it exposes patients to unwarranted risks and that patients should actively participate in decision-making and take a shared responsibility to protect their interests. There is a firm belief that the enterprise of medicine is something of value – both intrinsically because being healthy is good and instrumentally since being healthy allows us to do what we wish to, to attain happiness and (...) to live valuable lives. However, this can only hold if treatment is justified in terms of accepted evidence-based criteria. Imperative for all forms of treatment, including costly and invasive investigations, this is particularly true for surgical interventions because no surgery is without risk. Surgery performed outside of the norms of accepted indications constitutes a grave form of assault. Medicine is a noble cause if we stick to the rules and help each other to do so. As professionals, our most fundamental regulation is by ourselves. (shrink)

The transition towards sustainable and just food systems is ongoing, illustrated by an increasing number of initiatives that try to address unsustainable practices and social injustices. Insights are needed into what a just transition entails in order to critically engage with plural and potentially conflicting justice conceptualisations. Researchers play an active role in food system transitions, but it is unclear which conceptualisations and principles of justice they enact when writing about food system initiatives. To fill this gap this paper investigates: (...) Which conceptualisations of justice emerge from the literature related to food system initiatives and which principles of justice do authors use? We developed an initial framework for which we drew on political philosophy literature. We then undertook an extensive review of the food system transitions literature using this framework and were able to identify a range of recognition, distributive, and procedural justice conceptualisations and associated principles of justice. Recognised as subjects of justice were those with a particular role in the food system, people who are marginalised, Indigenous communities, those with experiences of negative consequences of the food system, future generations, and nonhumans. The identified conceptualisations and the developed framework can be used by those involved in food system initiatives to reflect on how they conceptualise justice. We challenge them to be more explicit about who they do and do not recognise as subjects of justice and which principles of justice they use. Such clarity is needed to reflexively enact a just transition towards sustainable and just food systems. (shrink)

Any theory of information needs to comply with what we call the implementation, formalization, and representation constraints. These constraints are justified by basic considerations concerning scientific modelling and methodology. In the first part of this paper, we argue that the implementation and formalization constraints cannot be satisfied because the relation between Shannon information and IIT must be clarified. In the second part of the paper, we focus on the representation constraint. We argue that IIT cannot succeed in satisfying this constraint (...) for semantic contents without offering models for concepts, conceptual roles, and context sensitivity. In the final part of the paper, further complications are raised with respect to the distinction between consciousness and attention, which apply more specifically to the representation constraint. We conclude with some recommendations as to how IIT may succeed in solving these problems, highlighting the advantages and enormous potential of IIT as a scientific theory. (shrink)

Was Metaphysik ist, läßt sich nicht apriorisch bestimmen, sondern zeigt sich erst in den denkerischen Entwürfen eines Ersten und Grundlegenden. Metaphysik ist, wie Philosophie überhaupt, von ihrer Geschichte nicht trennbar. Die philosophische Bedeutung der Periode des Mittelalters für den Gang der abendländischen Metaphysik ist in den letzten Jahrzehnten durch zwei klassische Studien herausgestellt worden.

In prevention and health promotion interventions, screening methods and risk profile assessments are often used as tools for establishing the interventions’ effectiveness, for the selection and determination of the health status of participants. The role these instruments fulfil in the creation of effectiveness and the effects these instruments have themselves remain unexplored. In this paper, we have analysed the role screening methods and risk profile assessments fulfil as part of prevention and health promotion programmes in the selection, enrolment and participation (...) of participants. Our analysis showed, that screening methods and health risk assessments create effects as they objectify health risks and/or the health status of individuals, i.e., they select the individuals ‘at risk’ and indicate the lifestyle modifications these people are required to make in order to improve their health. Yet, these instruments also reduce the group of participants thereby decreasing the possible effect of interventions, as they provide the legitimisation for people to make choices to whether they enrol or not and what lifestyle changes they incorporate into their lives. In other words, they present a space of interaction, in which agency is distributed across the practice nurses, the participants and the instruments. Decisions were not just made upon the projection of the outcomes of these instruments; decisions that were made by both the patients and practice nurses were the resultant of their opinions on these outcomes that were formed in interaction with the instruments.
