âLetâs pull these technologies out of the ivory towerâ: The politics, ethos, and ironies of participant-driven genomic research
This paper investigates how groups of âcitizen scientistsâ in non-traditional settings and primarily online networks claim to be challenging conventional genomic research processes and norms. Although these groups are highly diverse, they all distinguish their efforts from traditional university- or industry-based genomic research as being âparticipant-drivenâ in one way or another. Participant-driven genomic research (PDGR) groups often work from âlabsâ that consist of servers and computing devices as much as wet lab apparatus, relying on information-processing software for data-driven, discovery-based analysis rather than hypothesis-driven experimentation. We interviewed individuals from a variety of efforts across the expanding ecosystem of PDGR, including academic groups, start-ups, activists, hobbyists, and hackers, in order to compare and contrast how they relate their stated objectives, practices, and political and moral stances to institutions of expert scientific knowledge production. Results reveal that these groups, despite their diversity, share commitments to promoting alternative modes of housing, conducting, and funding genomic research and, ultimately, sharing knowledge. In doing so, PDGR discourses challenge existing approaches to research governance as well, especially the regulation, ethics, and oversight of human genomic information management. Interestingly, the reaction of the traditional genomics research community to this revolutionary challenge has not been negative: in fact, the community seems to be embracing the ethos espoused by PDGR, at the highest levels of science policy. As conventional genomic research assimilates the ethos of PDGR, the movementâs âdemocratizingâ views on research governance are likely to become normalized as well, creating new tensions for science policy and research ethics
Examining the ethical and social issues of health technology design through the public appraisal of prospective scenarios : a study protocol describing a multimedia-based deliberative method
Background: The design of health technologies relies on assumptions that affect how they will be implemented,
such as intended use, complexity, impact on user autonomy, and appropriateness. Those who design and
implement technologies make several ethical and social assumptions on behalf of users and society more broadly,
but there are very few tools to examine prospectively whether such assumptions are warranted and how the public
define and appraise the desirability of health innovations. This study protocol describes a three-year study that relies
on a multimedia-based prospective method to support public deliberations that will enable a critical examination
of the social and ethical issues of health technology design.
Methods: The first two steps of our mixed-method study were completed: relying on a literature review and the
support of our multidisciplinary expert committee, we developed scenarios depicting social and technical changes
that could unfold in three thematic areas within a 25-year timeframe; and for each thematic area, we created video
clips to illustrate prospective technologies and short stories to describe their associated dilemmas. Using this
multimedia material, we will: conduct four face-to-face deliberative workshops with members of the public (n = 40)
who will later join additional participants (n = 25) through an asynchronous online forum; and analyze and integrate
three data sources: observation, group deliberations, and a self-administered participant survey.
Discussion: This study protocol will be of interest to those who design and assess public involvement initiatives
and to those who examine the implementation of health innovations. Our premise is that using user-friendly tools
in a deliberative context that foster participantsâ creativity and reflexivity in pondering potential technoscientific
futures will enable our team to analyze a range of normative claims, including some that may prove problematic
and others that may shed light over potentially more valuable design options. This research will help fill an
important knowledge gap; intervening earlier in technological development could help reduce undesirable effects
and inform the design and implementation of more appropriate innovations
Big data, open science and the brain: lessons learned from genomics
The BRAIN Initiative aims to break new ground in the scale and speed of data collection in neuroscience, requiring tools to handle data in the magnitude of yottabytes (1024). The scale, investment and organization of it are being compared to the Human Genome Project (HGP), which has exemplified âbig scienceâ for biology. In line with the trend towards Big Data in genomic research, the promise of the BRAIN Initiative, as well as the European Human Brain Project, rests on the possibility to amass vast quantities of data to model the complex interactions between the brain and behavior and inform the diagnosis and prevention of neurological disorders and psychiatric disease. Advocates of this âdata drivenâ paradigm in neuroscience argue that harnessing the large quantities of data generated across laboratories worldwide has numerous methodological, ethical and economic advantages, but it requires the neuroscience community to adopt a culture of data sharing and open access to benefit from them. In this article, we examine the rationale for data sharing among advocates and briefly exemplify these in terms of new âopen neuroscienceâ projects. Then, drawing on the frequently invoked model of data sharing in genomics, we go on to demonstrate the complexities of data sharing, shedding light on the sociological and ethical challenges within the realms of institutions, researchers and participants, namely dilemmas around public/private interests in data, (lack of) motivation to share in the academic community, and potential loss of participant anonymity. Our paper serves to highlight some foreseeable tensions around data sharing relevant to the emergent âopen neuroscienceâ movement
Integrating genomics into clinical oncology: Ethical and social challenges from proponents of personalized medicine
The use of molecular tools to individualize health care, predict appropriate therapies and prevent adverse health outcomes has gained significant traction in the field of oncology, under the banner of âpersonalized medicine.â Enthusiasm for personalized medicine in oncology has been fueled by success stories of targeted treatments for a variety of cancers based on their molecular profiles. Though these are clear indications of optimism for personalized medicine, little is known about the ethical and social implications of personalized approaches in clinical oncology. The objective of this study is to assess how a range of stakeholders engaged in promoting, monitoring, and providing personalized medicine understand the challenges of integrating genomic testing and targeted therapies into clinical oncology. The study involved the analysis of in-depth interviews with 117 basic scientists, clinician-researchers, clinicians in private practice, health professional educators, representatives of funding agencies, medical journal editors, entrepreneurs, and insurers whose experiences and perspectives on personalized medicine span a wide variety of institutional and professional settings. Despite considerable enthusiasm for this shift, promoters, monitors and providers of personalized medicine identified four domains which will still provoke heightened ethical and social concerns: (1) informed consent for cancer genomic testing, (2) privacy, confidentiality, and disclosure of genomic test results, (3) access to genomic testing and targeted therapies in oncology, and (4) the costs of scaling up pharmacogenomic testing and targeted cancer therapies. These specific concerns are not unique to oncology, or even genomics. However, those most invested in the success of personalized medicine view oncologistsâ responses to these challenges as precedent-setting because oncology is farther along the path of clinical integration of genomic technologies than other fields of medicine. This study illustrates that the rapid emergence of personalized medicine approaches in clinical oncology provides a crucial lens for identifying and managing potential frictions and pitfalls that emerge as health care paradigms shift in these directions
After the revolution? Ethical and social challenges in âpersonalized genomic medicineâ
Personalized genomic medicine (PGM) is a goal that currently unites a wide array of biomedical initiatives, and is promoted as a ânew paradigm for healthcareâ by its champions. Its promissory virtues include individualized diagnosis and risk prediction, more effective prevention and health promotion, and patient empowerment. Beyond overcoming scientific and technological hurdles to realizing PGM, proponents may interpret and rank these promises differently, which carries ethical and social implications for the realization of PGM as an approach to healthcare. We examine competing visions of PGMâs virtues and the directions in which they could take the field, in order to anticipate policy choices that may lie ahead for researchers, healthcare providers and the public
Aging Expectations Predict Subjective Cognitive Decline Among Community-Dwelling Older Adults
Purpose: Subjective cognitive decline (SCD), or perceived decline in cognition, is a precursor to mild cognitive impairment, a prodrome of Alzheimerâs disease. SCDâs predictive utility is limited as it is impacted by multiple psychosocial factors. Expectations regarding aging among older adults have been linked to self-efficacy and health-related outcomes; however, their relationship with SCD is unknown. The aim of this cross-sectional study was to investigate the relationships between older adultsâ aging expectations regarding physical, mental, and cognitive health, and SCD.
Methods: An online survey of community-dwelling adults aged 65 years or older (n=582, M(SD)=71.36(4.80)) with no history of dementia or cognitive impairment was conducted in the United States. Measures included the Expectations Regarding Aging scale (ERA-12), the Everyday Cognition scale (ECog-12), as well as demographics and self-reported health. General linear models demonstrated relationships between the physical, mental, and cognitive expectations subscales of the ERA-12 and ECog-12 scores.
Results:All three domains of aging expectations regarding physical health (b(SE)=-0.033(0.007), p
Conclusion: Older adults\u27 aging expectations were predictive of subjective cognitive decline (SCD) across all domains, indicating a broader impact beyond cognitive function alone. Future research should explore whether this relationship holds in other patient populations, including middle-aged adults and different ethnic groups and whether interventions to modify aging expectations may promote positive perceptions of cognitive function among older adults, which can improve cognitive outcomes.https://jdc.jefferson.edu/aoa_research_symposium_posters/1012/thumbnail.jp
Temporal, Spectral, and Polarization Dependence of the Nonlinear Optical Response of Carbon Disulfide
Carbon disulfide is the most popular material for applications of nonlinear optical (NLO) liquids, and is frequently used as a reference standard for NLO measurements. Although it has been the subject of many investigations, determination of the third-order optical nonlinearity of CS2 has been incomplete. This is in part because of several strong mechanisms for nonlinear refraction (NLR), leading to a complex pulse width dependence. We expand upon the recently developed beam deflection technique, which we apply, along with degenerate four-wave mixing and Z-scan, to quantitatively characterize (in detail) the NLO response of CS2, over a broad temporal range, spanning 6 orders of magnitude (âŒ32 fs to 17 ns). The third-order response function, consisting of both nearly instantaneous bound-electronic and noninstantaneous nuclear contributions, along with the polarization and wavelength dependence from 390 to 1550 nm, is extracted from these measurements. This paper provides a self-consistent, quantitative picture of the third-order NLO response of liquid CS2, establishing it as an accurate reference material over this broad temporal and spectral range. These results allow prediction of the outcome of any NLR experiment on CS2

Gatekeepers or Intermediaries? The Role of Clinicians in Commercial Genomic Testing
BACKGROUND: Many commentators on ââdirect-to-consumerââ genetic risk information have raised concerns that giving results to individuals with insufficient knowledge and training in genomics may harm consumers, the health care system, and society. In response, several commercial laboratories offering genomic risk profiling have shifted to more traditional ââdirect-to-providerââ (DTP) marketing strategies, repositioning clinicians as the intended recipients of advertising of laboratory services and as gatekeepers to personal genomic information. Increasing popularity of next generation sequencing puts a premium on ensuring that those who are charged with interpreting, translating, communicating and managing commercial genomic risk information are appropriately equipped for the job. To shed light on their gatekeeping role, we conducted a study to assess how and why early clinical users of genomic risk assessment incorporate these tools in their clinical practices and how they interpret genomic information for their patients.
METHODS and FINDINGS: We conducted qualitative in-depth interviews with 18 clinicians providing genomic risk assessment services to their patients in partnership with DNA Direct and Navigenics. Our findings suggest that clinicians learned most of what they knew about genomics directly from the commercial laboratories. Clinicians rely on the expertise of the commercial laboratories without the ability to critically evaluate the knowledge or assess risks.
CONCLUSIONS: DTP service delivery model cannot guarantee that providers will have adequate expertise or sound clinical judgment. Even if clinicians want greater genomic knowledge, the current market structure is unlikely to build the independent substantive expertise of clinicians, but rather promote its continued outsourcing. Because commercial laboratories have the most ââskin in the gameââ financially, genetics professionals and policymakers should scrutinize the scientific validity and clinical soundness of the process by which these laboratories interpret their findings to assess whether self-interested commercial sources are the most appropriate entities for gate-keeping genomic interpretation
Patient-Provider Communication about Cognition and the Role of Memory Concerns: A Descriptive Study
Introduction 40% of Alzheimerâs disease cases could be delayed or prevented with early intervention1 Early detection remains challenging due to lack of consensus regarding screening, time constraints Subjective memory decline (SMD): âthe perception of a decline in memory ability when objective cognitive testing indicates normal performance.â2 Linked to early stages of Alzheimerâs Disease and mild cognitive impairment (MCI) Older adults with SCD up to 4 times more likely to develop MCI or dementia3 Older adults consider severity of problems, potential benefits or consequences of disclosing concerns, as well as past interactions with healthcare providers when discussing cognition4 Most older adults do not seek help until cognitive problems are severe and affect activities of daily living5 Previous work has not examined the role of SMD and memory concerns on discussions about cognitio
