Mepolizumab as an effective treatment in a case of hypophysitis in eosinophilic granulomatosis with polyangiitis
Granulomatosis or eosinophilic granulomatosis with polyangiitis (GPA/EGPA) can affect multiple organs resulting in heterogeneous symptoms and phenotypes. Pituitary gland dysfunction rarely occurs in GPA (1–3%) and even less in EGPA (two case reports). Here, we report a case of a 51-year-old female patient with a four-year history of EGPA who presented with new polydipsia and polyuria. Laboratory testing and magnetic resonance imaging (MRI) confirmed pituitary gland dysfunction caused by a hypophysitis. Therapeutic adjustment with a switch from dupilumab to mepolizumab resulted in a decrease in clinical symptoms, inflammation in MRI, and normalization of C-reactive protein in serum. This case underlines hypophysitis as a rare organ involvement also in EGPA. Moreover, this case demonstrates the responsiveness of neuroinflammatory manifestations to the recently approved anti-interleukin-5 monoclonal antibody mepolizumab as a new potential treatment option
Appeals to evidence for the resolution of wicked problems: the origins and mechanisms of evidentiary bias
Wicked policy problems are often said to be characterized by their ‘intractability’, whereby appeals to evidence are unable to provide policy resolution. Advocates for ‘Evidence Based Policy’ (EBP) often lament these situations as representing the misuse of evidence for strategic ends, while critical policy studies authors counter that policy decisions are fundamentally about competing values, with the (blind) embrace of technical evidence depoliticizing political decisions. This paper aims to help resolve these conflicts and, in doing so, consider how to address this particular feature of problem wickedness. Specifically the paper delineates two forms of evidentiary bias that drive intractability, each of which is reflected by contrasting positions in the EBP debates: ‘technical bias’ - referring to invalid uses of evidence; and ‘issue bias’ - referring to how pieces of evidence direct policy agendas to particular concerns. Drawing on the fields of policy studies and cognitive psychology, the paper explores the ways in which competing interests and values manifest in these forms of bias, and shape evidence utilization through different mechanisms. The paper presents a conceptual framework reflecting on how the nature of policy problems in terms of their complexity, contestation, and polarization can help identify the potential origins and mechanisms of evidentiary bias leading to intractability in some wicked policy debates. The discussion reflects on whether being better informed about such mechanisms permit future work that may lead to strategies to mitigate or overcome such intractability in the future
Once the shovel hits the ground : Evaluating the management of complex implementation processes of public-private partnership infrastructure projects with qualitative comparative analysis
Much attention is being paid to the planning of public-private partnership (PPP) infrastructure projects. The subsequent implementation phase – when the contract has been signed and the project ‘starts rolling’ – has received less attention. However, sound agreements and good intentions in project planning can easily fail in project implementation. Implementing PPP infrastructure projects is complex, but what does this complexity entail? How are projects managed, and how do public and private partners cooperate in implementation? What are effective management strategies to achieve satisfactory outcomes? This is the fi rst set of questions addressed in this thesis. Importantly, the complexity of PPP infrastructure development imposes requirements on the evaluation methods that can be applied for studying these questions. Evaluation methods that ignore complexity do not create a realistic understanding of PPP implementation processes, with the consequence that evaluations tell us little about what works and what does not, in which contexts, and why. This hampers learning from evaluations. What are the requirements for a complexity-informed evaluation method? And how does qualitative comparative analysis (QCA) meet these requirements? This is the second set of questions addressed in this thesis
Living with the dead:emergent post-mortem digital curation and creation practices
This chapter explores the emergent digital dimension of contemporary Western mourning, by utilising a historical framework and a postmodern, post-disciplinary and practice theory lens, in order to critically discuss how the ruptures of loss and the presence of the dead are radically manifesting in the digital age. We begin with a contextual overview of the historical landscape of mourning, its perceived decline and the twentieth century gaze toward private grief, before proceeding to introduce the paradigm of continuing bonds and the social presence of the dead. From this contextualisation, the chapter then introduces twenty-first century digital mourning through a discussion of the emergent practices which curate and create the spectral presence of the dead online. We argue that mourning has not collapsed, but is radically manifest in ways currently unaccounted for and invisible within the dominant filter of memorialisation. Finally, we introduce a range of potential implications and challenges that will be faced by HCI researchers and designers of systems supporting the ‘End of Life’, by highlighting the emerging socio-cultural complexity in need of consideration when designing technologies for bereavement support
