Genetic Testing Integration Panels (GTIPs): A Novel Approach for Considering Integration of Direct‐To‐Consumer and Other New Genetic Tests into Patient Care

There has been a dramatic increase in the number of genetic tests available but few tests have practice guidelines. In addition, many tests have become available outside of clinical settings through direct‐to‐consumer (DTC) companies and several offer tests not considered standard of care. To address several practical challenges associated with the rapid introduction of clinical and DTC genetic tests, we propose that genetic counselors and geneticists organize expert panels in their institutions to discuss the integration of new tests into patient care. We propose the establishment of Genetic Testing Integration Panels (GTIPs) to bring together local experts in medical genetics, genetic counseling, bioethics and law, health communication and clinical laboratory genetics. We describe key features of this approach and consider some of the potential advantages and limitations of using a GTIP to address the many clinical challenges raised by rapidly emerging clinical and DTC genetic tests.Peer Reviewedhttps://deepblue.lib.umich.edu/bitstream/2027.42/147023/1/jgc40374.pd

Marketing the Research Missions of Academic Medical Centers: Why Messages Blurring Lines Between Clinical Care and Research Are Bad for both Business and Ethics.

Academic Medical Centers (AMCs) offer patient care and perform research. Increasingly, AMCs advertise to the public in order to garner income that can support these dual missions. In what follows, we raise concerns about the ways that advertising blurs important distinctions between them. Such blurring is detrimental to AMC efforts to fulfill critically important ethical responsibilities pertaining both to science communication and clinical research, because marketing campaigns can employ hype that weakens research integrity and contributes to therapeutic misconception and misestimation, undermining the informed consent process that is essential to the ethical conduct of research. We offer ethical analysis of common advertising practices that justify these concerns. We also suggest the need for a deliberative body convened by the Association of American Medical Colleges and others to develop a set of voluntary guidelines that AMCs can use to avoid in the future, the problems found in many current AMC advertising practices

White matter damage and cognitive impairment after traumatic brain injury

White matter disruption is an important determinant of cognitive impairment after brain injury, but conventional neuroimaging underestimates its extent. In contrast, diffusion tensor imaging provides a validated and sensitive way of identifying the impact of axonal injury. The relationship between cognitive impairment after traumatic brain injury and white matter damage is likely to be complex. We applied a flexible technique—tract-based spatial statistics—to explore whether damage to specific white matter tracts is associated with particular patterns of cognitive impairment. The commonly affected domains of memory, executive function and information processing speed were investigated in 28 patients in the post-acute / chronic phase following traumatic brain injury and in 26 age-matched controls. Analysis of fractional anisotropy and diffusivity maps revealed widespread differences in white matter integrity between the groups. Patients showed large areas of reduced fractional anisotropy, as well as increased mean and axial diffusivities, compared with controls, despite the small amounts of cortical and white matter damage visible on standard imaging. A stratified analysis based on the presence or absence of microbleeds (a marker of diffuse axonal injury) revealed diffusion tensor imaging to be more sensitive than gradient-echo imaging to white matter damage. The location of white matter abnormality predicted cognitive function to some extent. The structure of the fornices was correlated with associative learning and memory across both patient and control groups, whilst the structure of frontal lobe connections showed relationships with executive function that differed in the two groups. These results highlight the complexity of the relationships between white matter structure and cognition. Although widespread and, sometimes, chronic abnormalities of white matter are identifiable following traumatic brain injury, the impact of these changes on cognitive function is likely to depend on damage to key pathways that link nodes in the distributed brain networks supporting high-level cognitive functions
