Competing realities, uncertain diagnoses of infectious disease: Mass self-testing for COVID-19 and liminal bio-citizenship.

Diagnoses of infectious diseases are being transformed as mass self-testing using rapid antigen tests (RATs) is increasingly integrated into public health. Widely used during the COVID-19 pandemic, RATs are claimed to have many advantages over 'gold-standard' polymerase chain reaction tests, especially their ease of use and production of quick results. Yet, while laboratory studies indicate the value of RATs in detecting the SARS-CoV-2 virus antigen, uncertainty surrounds their deployment and ultimate effectiveness in stemming infections. This article applies the analytic lens of biological citizenship (or bio-citizenship) to explore Australia's experience of implementing a RAT-based mass self-testing strategy to manage COVID-19. Drawing on Annemarie Mol's (1999, The Sociological Review, 47(1), 74-89) concept of ontological politics and analysing government statements, scientific articles and news media reporting published during a critical juncture of the strategy's implementation, we explore the kind of bio-citizenship implied by this strategy. Our analysis suggests the emergence of what we call liminal bio-citizenship, whereby citizens are made responsible for self-managing infection risk without the diagnostic certitude this demands. We discuss how the different realities of mass self-testing interact to reinforce this liminal citizenship and consider the implications for the sociology of diagnosis.

The relatives of people with depression: A systematic review and methodological critique of qualitative studies.

Being a close relative of a person with depression can take a heavy toll on the former, but these relatives are increasingly made responsible for taking on extensive carer roles. Research on relatives of people with depression is currently dominated by a focus on "carer burden" and although such a focus can explain many relatives' experiences and daily lives, it provides very limited insight into the everyday life of a person living with someone with depression. Therefore, we scoped qualitative research on people who are relatives of people living with depression and identified knowledge gaps caused by explicit or implicit theoretical or methodological assumptions. We conducted an exhaustive literature search in CINAHL, PubMed, PsycINFO, Sociological Abstracts, and Eric. In total, 34 publications were included, their quality evaluated and their findings mapped and summarized. We identified four interrelated and overlapping themes that dominated the findings of the publications: (a) recognition of "depression", (b) emotional responses, (c) interruptions of relationships, and (d) a staged psychosocial process. The vast majority of studies presented de-contextualized and underinterpreted analyses assuming a homogeneity of (illness) experiences and disregarded the important influence of social contributors to social relationships, connectedness, and mental health problems.

Artificial Intelligence in Long-Term Care: Technological Promise, Aging Anxieties, and Sociotechnical Ageism.

This article explores views about older people and aging underpinning practices and perceptions of development and implementation of Artificial Intelligence (AI) in long-term care homes (LTC). Drawing on semi-structured interviews with seven AI developers, seven LTC staff, and four LTC advocates, we analyzed how AI technologies for later life are imagined, designed, deployed, and resisted. Using the concepts of "promissory discourse" and "aging anxieties", we investigated manifestations of ageism in accounts of AI applications in LTC. Despite positive intentions, both AI developers and LTC staff/advocates engaged in simplistic scripts about aging, care, and the technological capacity of older people. We further uncovered what we termed sociotechnical ageism-a form that is not merely digital but rests on interacting pre-conceptions about the inability or lack of interest of older people to use emerging technologies coupled with social assumptions about aging, LTC, and technological innovation.

'A platform for goodness, not for badness': The heuristics of hope in patients' evaluations of online health information.

Patient advocates and activists are increasingly relying on online health information that can assist them to manage their health condition. Yet once online, they will confront diverse information whose veracity and utility are difficult to determine. This article offers a sociological analysis of the practical methods, or heuristics, that patient advocates and activists use when making judgements about the credibility and utility of online information. Drawing on the findings from interviews with fifty Australian patient advocates and activists, it is argued that these individuals' use of these heuristics reflects their hopes that information can help them manage their condition which may, in some cases, override fears and uncertainties that arise during searches. The article identifies the common 'rules-of-thumb'-or what we call the 'heuristics of hope'-that patient advocates/activists may use to make judgements and highlights the dangers of over-reliance on them, especially regarding clinically unproven, potentially unsafe treatments. Analyses of the heuristics of hope, we conclude, can assist in understanding the dynamics of decision-making and the role that affect plays in online patient communities which is crucial in an age characterised by the rapid circulation of emotionally charged messages, often based on hope.

Searching for diagnostic certainty, governing risk: Patients' ambivalent experiences of medical testing.

Diagnosis is pivotal to medicine's epistemic system: it serves to explain individual symptoms, classify them into recognizable conditions and determine their prognosis and treatment. Medical tests, or investigative procedures for detecting and monitoring disease, play a central role in diagnosis. While testing promises diagnostic certainty or a definitive risk assessment, it often produces uncertainties and new questions which call for yet further tests. In short, testing, regardless of its specific application, is imbued with meaning and emotionally fraught. In this article, we explore individuals' ambivalent experiences of testing as they search for diagnostic certainty, and the anxieties and frustrations of those for whom it remains elusive. Combining insights from sociological work on ambivalence and the biopolitics of health, and drawing on qualitative interviews with Australian healthcare recipients who have undergone testing in the context of clinical practice, we argue that these experiences are explicable in light of the contradictory impulses and tensions associated with what we term 'bio-subjectification'. We consider the implications of our analysis in light of the development of new tests that produce ever finer delineations between healthy and diseased populations, concluding that their use will likely multiply uncertainties and heighten rather than lessen anxieties.

From the margins to mainstream: How providers of autologous 'stem cell treatments' legitimise their practice in Australia.

This article examines how Australian providers of unproven autologous 'stem cell treatments' legitimise these products and their practices. We focus on the strategies employed by providers in their efforts to create and sustain a market for procedures that have yet to be proven safe and clinically efficacious. Drawing on the work of Thomas Gieryn and Pierre Bourdieu and the findings of research involving an analysis of direct-to-consumer online advertising of clinics that sell purported 'stem cell treatments' and interviews with clinicians who provide them, we examine the mechanisms by which medical legitimacy for these products is established and defended. We argue that Australian providers employ a number of strategies in order to create medical legitimacy for the use and sale of scientifically unproven therapies. A key strategy employed by providers of stem cell treatments is to use markers of social distinction, drawing strongly on the symbols of science, to confirm their legitimacy and differentiate their own practices from those of other providers, who are posited as operating outside the boundary of accepted practice and hence illegitimate. We argue there is a paradox at the heart of the autologous stem cell treatment market. Providers aim to create legitimacy for their work by emphasising the potential benefits of their 'treatments', their expertise and the professionalisation of their practices in an environment where regulators are yet to take a firm stance; they are also required to undertake the challenging task of managing patients' hopes and expectations that both enable and potentially jeopardise their operations and revenue. We conclude by suggesting that providers' creation of symbolic capital to establish medical legitimacy is a crucial means by which they seek to bring unproven 'stem cell treatments' from the margins of medicine into the mainstream and to portray themselves as medical pioneers rather than medical cowboys who exploit vulnerable patients.

Managing risks or generating uncertainties? Ambiguous ontologies of testing in Australian healthcare.

Medical testing promises to establish certainty by providing a definitive assessment of risk or diagnosis. But can those who rely on tests to offer advice or make clinical decisions be assured of this certainty? This article examines how Australian health professionals, namely clinicians, microbiologists, specialist physicians and health policymakers, delineate the boundary between certainty and uncertainty in their accounts of medical testing. Applying concepts from science and technology studies, and drawing on qualitative data from a sociological study of testing in Australian healthcare, we consider how professionals ascribe meaning to testing and test results. As we argue, for these health professionals, the 'evidence' that testing generates has ambiguous ontological significance: while it promises to provide diagnostic certainty and clear direction for advice or treatment, it also generates uncertainties that may lead to yet further tests. Our analysis leads us to question a key premise of testing, namely that it is possible to establish certainty in medical practice via the measurement of individual health risks and disease markers. Against this dominant view, the responses of the health professionals in our study suggest that uncertainty is intrinsic to testing due to the constantly changing, unstable character of 'evidence'. We conclude by considering the implications of our analysis in light of healthcare's increasing reliance on sophisticated technologies of 'personalised' testing using genetic information and data analytics.

Feeling less alone online: patients' ambivalent engagements with digital media.

Digital media offer the chronically ill, especially those who experience related isolation, unparalleled opportunities to connect with others. This article asks, how do these individuals ascribe meaning to and use these media to manage their condition and related isolation? Using the concepts of affordance and emotional community, and drawing on the findings from an Australian study on patients' use of digital media, we examine individuals' ambivalent ascriptions of media, which are both feared and distrusted for the risks they present and embraced as invaluable tools of social connection. We argue that this ambivalence is explicable in terms of the communities to which the chronically ill belong which are founded on strong emotional bonds. In a context in which individuals tend to feel isolated through pain and/or stigmatisation, digital media may offer powerful means for sharing and affirming their experiences, the subjective benefits of which may outweigh the perceived risks. The article discusses the functions and features of digital media that the chronically ill value and distrust and concludes by considering the implications of our analysis for strategies to address the needs of people who feel isolated as a consequence of their condition.

Navigating the cartographies of trust: how patients and carers establish the credibility of online treatment claims.

Digital media offer citizens novel ways of 'enacting' health and illness, and treatment and care. However, while digital media may so 'empower' citizens, those searching for credible information will be confronted with various, often-conflicting claims that may have 'disempowering' effects. This article uses Gieryn's concept of the 'cultural cartography' to explore the criteria that patients and carers employ in establishing the credibility of information on alleged treatments. Drawing on data from interviews with Australian patients and carers who have travelled or considered travelling abroad for unproven commercial stem cell treatments, the article examines how individuals assess rival sources of epistemic authority - science-based and non-science-based - as they search for credible information. As we argue, in a context where conventional treatment options are perceived to be limited or non-existent - which is likely to be the case with those suffering severe, life-limiting conditions - and the credibility of sources uncertain, matters of opinion and belief are prone to being interpreted as matters of fact, with potentially far-reaching implications for citizens' health. Revealing the mechanisms by which individuals ascribe credibility to health information, we conclude, has become crucial as digital media assume a growing role in health and healthcare and governments encourage citizens to become 'digitally literate'.

Matters of fact and politics: Generating expectations of cancer screening.

Many countries, including Australia, the United Kingdom and the United States have established national screening programs in the effort to advance the early diagnosis of cancers. Australia has population screening programs for breast, bowel and cervical cancers, and this article focuses on breast and cervical cancer screening as the two longest running programs in Australia. While these screening programs are well-established and report relatively high participation rates, the effectiveness of population screening is a contested issue, subject to significant, ongoing debate about its purported benefits (Armstrong, 2019). In this article, we draw on ideas from sociology of science on the construction of scientific facts to analyse how evidentiary claims are presented in policy documents for Australia's breast and cervical cancer screening programs, and the implications for those who are the targets of screening. We explore how screening-related information assumes the status of scientific 'facts', and argue that presenting information as neutral and objective obscures the political choices involved in its generation. Importantly, some of the claims presented in the policy documents have a tendency to emphasise the benefits, and minimise the risks and harms of population-based screening. In doing so, we suggest that the current national policies may be contributing to sustaining expectations of screening that are higher than warranted. Higher expectations may bring with them unintended societal and economic costs to the public. We conclude by noting how deeply ingrained socio-cultural meanings of cancer shape public expectations of the protective value of screening, which allows current screening approaches to become further entrenched and resistant to challenge.

Citizens' use of digital media to connect with health care: Socio-ethical and regulatory implications.

Digital technologies promise to transform practices of health, medicine and health care and 'power' economies. In expectation of their presumed future benefits, governments in recent years have invested heavily in new technology initiatives and have sought to engender 'digital literacy' among citizens. This article introduces papers and expands on themes arising from a special issue that explores the socio-ethical and regulatory implications of citizens' use of digital media to connect with health care. We set the scene by examining the promissory discourse that attaches to digital technologies as applied to health care, and its role in shaping actions, and then consider the longer term prospects and implications of digitalisation for conceptions of citizenship and established categories and distinctions. As we argue, given the history of new technologies, the longer term implications of digitalisation are likely to differ significantly from those envisaged. Digital technologies promise radical positive disruption. Yet many uncertainties accompany their development and future applications and likely implications. Making reference to papers in the special issue and the wider literature, the article considers the prospects of digitalisation in medicine and health care in light of the colonisation of the Internet by powerful technology companies, the shift in capitalist economies from processes of production to technologies of prediction, evidence of inequalities in access to the Internet and related devices, and the growing number of data breaches involving personal health information. We draw attention to the failure of governments to engage citizens in substantive deliberations about digitalisation and its future potential implications and the ultimate democratic deficit that this represents. We ask, what does it mean to 'regulate' digital media in a context in which data are widely viewed as the 'new oil'? While we have no straightforward answers, we suggest that recent legislative efforts (e.g. General Data Protection Regulation in Europe) and growing calls for 'algorithmic accountability' have the potential to temper the more harmful aspects of digitalisation.

Recovery Within Injury Compensation Schemes: A System Mapping Study.

Purpose Many industrialised nations have systems of injury compensation and rehabilitation that are designed to support injury recovery and return to work. Despite their intention, there is now substantial evidence that injured people, employers and healthcare providers can experience those systems as difficult to navigate, and that this can affect injury recovery. This study sought to characterise the relationships and interactions occurring between actors in three Australian injury compensation systems, to identify the range of factors that impact on injury recovery, and the interactions and inter-relationships between these factors. Methods This study uses data collected directly from injured workers and their family members via qualitative interviews, analysed for major themes and interactions between themes, and then mapped to a system level model. Results Multiple factors across multiple system levels were reported by participants as influencing injury recovery. Factors at the level of the injured person's immediate environment, the organisations and personnel involved in rehabilitation and compensation processes were more commonly cited than governmental or societal factors as influencing physical function, psychological function and work participation. Conclusions The study demonstrates that injury recovery is a complex process influenced by the decisions and actions of organisations and individuals operating across multiple levels of the compensation system. Changes occurring 'upstream', for instance at the level of governmental or organisational policy, can impact injury recovery through both direct and diffuse pathways.

Altered VEGF Signaling Leads to Defects in Heart Tube Elongation and Omphalomesenteric Vein Fusion in Quail Embryos.

Formation of the endocardial and myocardial heart tubes involves precise cardiac progenitor sorting and tissue displacements from the primary heart field to the embryonic midline-a process that is dependent on proper formation of conjoining great vessels, including the omphalomesenteric veins (OVs) and dorsal aortae. Using a combination of vascular endothelial growth factor (VEGF) over- and under-activation, fluorescence labeling of cardiac progenitors (endocardial and myocardial), and time-lapse imaging, we show that altering VEGF signaling results in previously unreported myocardial, in addition to vascular and endocardial phenotypes. Resultant data show: (1) exogenous VEGF leads to truncated endocardial and myocardial heart tubes and grossly dilated OVs; (2) decreased levels of VEGF receptor 2 tyrosine kinase signaling result in a severe abrogation of the endocardial tube, dorsal aortae, and OVs. Surprisingly, only slightly altered myocardial tube fusion and morphogenesis is observed. We conclude that VEGF has direct effects on the VEGF receptor 2-bearing endocardial and endothelial precursors, and that altered vascular morphology of the OVs also indirectly results in altered myocardial tube formation.

The shifting politics of patient activism: From bio-sociality to bio-digital citizenship.

Digital media provide novel tools for patient activists from disease- and condition-specific communities. While those with debilitating conditions or disabilities have long recognised the value of collective action for advancing their interests, digital media offer activists unparalleled opportunities to fulfil their goals. This article explores the shifting politics of 'activism' in the increasingly digitally mediated, commercialised context of healthcare, asking: what role have digital media played in the repertoire of activists' strategies? And, to what extent and how has the use of such media impacted the very concept of activism? Building on sociological ideas on emergent forms of 'biological citizenship' and drawing on findings from an analysis of available media, including television and print news reportage, online communications, published histories and campaign material and other information produced by activists in HIV/AIDS and breast cancer communities, we argue that digital media have profoundly shaped how 'activism' is enacted, both the goals pursued and the strategies adopted, which serve to broadly align contemporary patient communities' interests with those of science and business. This alignment, which we characterise as 'bio-digital citizenship', has involved a fundamental reorientation of 'activism' from less of a struggle for rights to more of a striving to achieve a public profile and attract funding. We conclude by calling for a reconceptualisation of 'activism' to more adequately reflect the workings of power in the digital age, whereby the agency and hopes of citizens are central to the workings of political rule.

The Advanced Solid State Lasers 2017 Conference (ASSL) was held from October 1 to 5, 2017. It was an extraordinary conference at the Nagoya Congress Center in Nagoya, Japan. ASSL 2017 again suggested an impressive platform where miscellaneous perceptions with a variety of approaches to optics, photonics, sensing, laser technology, laser systems, and solid state lasers were presented. This international meeting was highly selective, leading to high level contributions through one plenary conference, 17 invited presentations, 70 regular talks, and 121 posters. The present joint issue of Optics Express and Optical Materials Express features 27 articles written by ASSL 2017 authors and covering the spectrum of solid-state lasers from materials research to sources, and from design innovation to applications.

'No one here's helping me, what do you do?': addressing patient need for support and advice about stem cell treatments.

AIM: This article examines how those who contemplate purported stem cell treatments (SCTs) negotiate available information sources and the adequacy of current approaches to guidance and support. MATERIALS & METHODS: Qualitative interviews undertaken with people who had contemplated or undergone purported SCTs for a range of conditions (n = 24 and n = 27, respectively), as well as professionals who are frequently asked about SCTs (n = 20) were analyzed. RESULTS: Our findings reveal the difficulties for individuals in discriminating between different sources of information on SCTs and the limitations of current responses. CONCLUSION: In the context of contending information about SCTs informal ('accidental') advisors potentially play a crucial role in supporting patients. Additional approaches are also required to better address patients' needs.

Stuck in the middle: The emotional labours of case managers in the personal injury compensation system.

BACKGROUND: Case managers within injury compensation systems are confronted with various emotional demands. OBJECTIVE: Employing the concept of emotional labour, this paper explores distinctive aspects of these demands. METHODS: The findings are drawn from focus groups with 21 Australian case managers. RESULTS: Case managers work was characterised by extra-role commitments, emotional control, stress and balancing tensions arising from differing stakeholder expectations about outcomes related to compensation and return to work. CONCLUSIONS: By examining the experiences of case managers, the findings add to the literature on the emotional labour of front line service workers, especially with respect to the demands involved in managing the conflicting demands of work.
