A comparison of institutional review board professionals' and patients' views on consent for research on medical practices.
2016; 13 (5): 555-565
In the context of research on medical practices, which includes comparative effectiveness research and pragmatic clinical trials, empirical studies have begun to raise questions about the extent to which institutional review boards' interpretations and applications of research regulations align with patients' values. To better understand the similarities and differences between these stakeholder groups, we compare and contrast two surveys: one of institutional review board professionals and one of patients, which examine views on consent for research on medical practices.We conducted online surveys of two target populations between July 2014 and March 2015. We surveyed 601 human subjects research professionals out of 1500 randomly selected from the Public Responsibility in Medicine and Research membership list (40.1% response rate), limiting analysis to 537 respondents who reported having had institutional review board experience. We also surveyed 120 adult patients out of 225 approached at subspecialty clinics in Spokane, Washington (53.3% response rate). Our survey questions probed attitudes about consent in the context of research on medical practices using medical record review and randomization. The patient survey included three embedded animated videos to explain these concepts.A majority of institutional review board professionals distinguished between consent preferences for medical record review and randomization, ranked clinicians as the least preferred person to obtain participant consent (54.6%), and viewed written or verbal permission as the minimum acceptable consent approach for research on medical practices using randomization (87.3%). In contrast, most patients had similar consent preferences for research on medical practices using randomization and medical record review, most preferred to have consent conversations with their doctors rather than with researchers for studies using randomization (72.6%) and medical record review (67.0%), and only a few preferred to see research involving randomization (16.8%) or medical record review (13.8%) not take place if obtaining written or verbal permission would make the research too difficult to conduct. Limitations of our post hoc analysis include differences in framing, structure, and language between the two surveys and possible response bias.Our findings highlight a need to identify appropriate ways to integrate patient preferences into prevailing regulatory interpretations as institutional review boards increasingly apply research regulations in the context of research on medical practices. Dialogue between institutional review boards and research participants will be an important part of this process and should inform future regulatory guidance.

A randomized study of multimedia informational aids for research on medical practices: Implications for informed consent.
Participant understanding is a key element of informed consent for enrollment in research. However, participants often do not understand the nature, risks, benefits, or design of the studies in which they take part. Research on medical practices, which studies standard interventions rather than new treatments, has the potential to be especially confusing to participants because it is embedded within usual clinical care. Our objective in this randomized study was to compare the ability of a range of multimedia informational aids to improve participant understanding in the context of research on medical practices.We administered a web-based survey to members of a proprietary online panel sample selected to match national US demographics. Respondents were randomized to one of five arms: four content-equivalent informational aids (animated videos, slideshows with voice-over, comics, and text) and one no-intervention control. We measured knowledge of research on medical practices using a summary knowledge score from 10 questions based on the content of the informational aids. We used analysis of variance and paired t-tests to compare knowledge scores between arms.There were 1500 completed surveys (300 in each arm). Mean knowledge scores were highest for the slideshows with voice-over (65.7%), followed by the animated videos (62.7%), comics (60.7%), text (57.2%), and control (50.3%). Differences between arms were statistically significant except between the slideshows with voice-over and animated videos and between the animated videos and comics. Informational aids that included an audio component (animated videos and slideshows with voice-over) had higher knowledge scores than those without an audio component (64.2% vs 59.0%, p < .0001). There was no difference between informational aids with a character-driven story component (animated videos and comics) and those without.Our results show that simple multimedia aids that use a dual-channel approach, such as voice-over with visual reinforcement, can improve participant knowledge more effectively than text alone. However, the relatively low knowledge scores suggest that targeted informational aids may be needed to teach some particularly challenging concepts. Nonetheless, our results demonstrate the potential to improve informed consent for research on medical practices using multimedia aids that include simplified language and visual metaphors.

"This lifetime commitment": Public conceptions of disability and noninvasive prenatal genetic screening.
American journal of medical genetics. Part A
2016; 170A (2): 363-374
Recently, new noninvasive prenatal genetic screening technologies for Down syndrome and other genetic conditions have become commercially available. Unique characteristics of these screening tests have reignited long-standing concerns about prenatal testing for intellectual and developmental disabilities. We conducted a web-based survey of a sample of the US public to examine how attitudes towards disability inform views of prenatal testing in the context of these rapidly advancing prenatal genetic screening technologies. Regardless of opinion toward disability, the majority of respondents supported both the availability of screening and the decision to continue a pregnancy positive for aneuploidy. Individuals rationalized their support with various conceptions of disability; complications of the expressivist argument and other concerns from the disability literature were manifested in many responses analyzed.

Building a Central Repository for Research Ethics Consultation Data: A Proposal for a Standard Data Collection Tool.
Clinical and translational science
2015; 8 (4): 376-387
Clinical research ethics consultation services have been established across academic health centers over the past decade. This paper presents the results of collaboration within the CTSA consortium to develop a standard approach to the collection of research ethics consultation information to serve as a foundation for quality improvement, education, and research efforts. This approach includes categorizing and documenting descriptive information about the requestor, research project, the ethical question, the consult process, and describing the basic structure for a consult note. This paper also explores challenges in determining how to share some of this information between collaborating institutions related to concerns about confidentially, data quality, and informatics. While there is much still to be learned to improve the process of clinical research ethics consultation, these tools can advance these efforts, which, in turn, can facilitate the ethical conduct of research.

Attitudes Toward Risk and Informed Consent for Research on Medical Practices: A Cross-sectional Survey.
Annals of internal medicine
2015; 162 (10): 690-696
The U.S. Office for Human Research Protections has proposed that end points of randomized trials comparing the effectiveness of standard medical practices are risks of research that would require disclosure and written informed consent, but data are lacking on the views of potential participants.To assess attitudes of U.S. adults about risks and preferences for notification and consent for research on medical practices.Cross-sectional survey conducted in August 2014.Web-based questionnaire.1095 U.S. adults sampled from an online panel (n = 805) and an online convenience river sample (n = 290).Attitudes toward risk, informed consent, and willingness to participate in 3 research scenarios involving medical record review and randomization of usual medical practices.97% of respondents agreed that health systems should evaluate standard treatments. Most wanted to be asked for permission to participate in each of 3 scenarios (range, 75.2% to 80.4%), even if it involved only medical record review, but most would accept nonwritten (oral) permission or general notification if obtaining written permission would make the research too difficult to conduct (range, 70.2% to 82.7%). Most perceived additional risk from each scenario (range, 64.0% to 81.6%).Use of hypothetical scenarios and a nonprobability sample that was not fully representative of the U.S. population.Most respondents preferred to be asked for permission to participate in observational and randomized research evaluating usual medical practices, but they are willing to accept less elaborate approaches than written consent if research would otherwise be impracticable. These attitudes are not aligned with proposed regulatory guidance.National Center for Advancing Translational Sciences at the National Institutes of Health.

Research Ethics Consultation: Ethical and Professional Practice Challenges and Recommendations
2015; 90 (5): 615-620
The complexity of biomedical research has increased considerably in the last decade, as has the pace of translational research. This complexity has generated a number of novel ethical issues for clinical investigators, institutional review boards (IRBs), and other oversight committees. In response, many academic medical centers have created formal research ethics consultation (REC) services to help clinical investigators and IRBs navigate ethical issues in biomedical research. Key functions of a REC service include assisting with research design and implementation, providing a forum for deliberative exploration of ethical issues, and supplementing regulatory oversight. As increasing numbers of academic research institutions establish REC services, there is a pressing need for consensus about the primary aims and policies that should guide these activities. Establishing clear expectations about the aims and policies of REC services is important if REC programs are to achieve their full potential. Drawing on the experiences of a Clinical and Translational Science Award Research Ethics Consultation Working Group, this article describes three major ethical and professional practice challenges associated with the provision of REC: (1) managing multiple institutional roles and responsibilities, (2) managing sensitive information, and (3) communicating with consultation requestors about how these issues are managed. The paper also presents several practical strategies for addressing these challenges and enhancing the quality of REC services.

Demographic and experiential correlates of public attitudes towards cell-free fetal DNA screening.
Journal of genetic counseling
2014; 23 (6): 957-967
This study seeks to inform clinical application of cell-free fetal DNA (cffDNA) screening as a novel method for prenatal trisomy detection by investigating public attitudes towards this technology and demographic and experiential characteristics related to these attitudes. Two versions of a 25-item survey assessing interest in cffDNA and existing first-trimester combined screening for either trisomy 13 and 18 or trisomy 21 were distributed among 3,164 members of the United States public. Logistic regression was performed to determine variables predictive of interest in screening options. Approximately 47% of respondents expressed an interest in cffDNA screening for trisomy 13, 18, and 21, with a majority interested in cffDNA screening as a stand-alone technique. A significantly greater percent would consider termination of pregnancy following a diagnosis of trisomy 13 or 18 (52%) over one of trisomy 21 (44%). Willingness to consider abortion of an affected pregnancy was the strongest correlate to interest in both cffDNA and first-trimester combined screening, although markedly more respondents expressed an interest in some form of screening (69% and 71%, respectively) than would consider termination. Greater educational attainment, higher income, and insurance coverage predicted interest in cffDNA screening; stronger religious identification also corresponded to decreased interest. Prior experience with disability and genetic testing was associated with increased interest in cffDNA screening. Several of these factors, in addition to advanced age and Asian race, were, in turn, predictive of respondents' increased willingness to consider post-diagnosis termination of pregnancy. In conclusion, divergent attitudes towards cffDNA screening--and prenatal options more generally--appear correlated with individual socioeconomic and religious backgrounds and experiences with disability and genetic testing. Clinical implementation and counseling for novel prenatal technologies should take these diverse stakeholder values into consideration.

Views of genetics health professionals on the return of genomic results.
Journal of genetic counseling
2014; 23 (4): 531-538
As exome and whole genome sequencing become clinically available, the potential to receive a large number of clinically relevant but incidental results is a significant challenge in the provision of genomic counseling. We conducted three focus groups of a total of 35 individuals who were members of ASHG and/or NSGC, assessing views towards the return of genomic results. Participants stressed that patient autonomy was primary. There was consensus that a mechanism to return results to the healthcare provider, rather than patient, and to streamline integration into the electronic health record would ensure these results had the maximal impact on patient management. All three focus groups agreed that pharmacogenomic results were reasonable to return and that they were not felt to be stigmatizing. With regard to the return of medically relevant results, there was much debate. Participants had difficulty in consistently assigning specific diseases to 'bins' that were considered obligatory versus optional for disclosure. Consensus was reached regarding the importance of informed consent and pretest counseling visits to clarify what the return of results process would entail. Evidence based professional guidelines should continue to be developed and regularly revised to assist in consistently and appropriately providing genomic results to patients.

Genetic testing of children for predisposition to mood disorders: anticipating the clinical issues.
Journal of genetic counseling
2014; 23 (4): 566-577
Large-scale sequencing information may provide a basis for genetic tests for predisposition to common disorders. In this study, participants in the Coriell Personalized Medicine Collaborative (N = 53) with a personal and/or family history of Major Depressive Disorder or Bipolar Disorder were interviewed based on the Health Belief Model around hypothetical intention to test one's children for probability of developing a mood disorder. Most participants (87 %) were interested in a hypothetical test for children that had high ("90 %") positive predictive value, while 51 % of participants remained interested in a modestly predictive test ("20 %"). Interest was driven by beliefs about effects of test results on parenting behaviors and on discrimination. Most participants favored testing before adolescence (64 %), and were reluctant to share results with asymptomatic children before adulthood. Participants anticipated both positive and negative effects of testing on parental treatment and on children's self-esteem. Further investigation will determine whether these findings will generalize to other complex disorders for which early intervention is possible but not clearly demonstrated to improve outcomes. More information is also needed about the effects of childhood genetic testing and sharing of results on parent-child relationships, and about the role of the child in the decision-making process.

Attitudes towards non-invasive prenatal testing for aneuploidy among US adults of reproductive age.
Journal of perinatology
2014; 34 (6): 429-434
Objective:To determine how adults in the United States view non-invasive prenatal testing using cell-free fetal DNA (cffDNA testing) in order to help estimate uptake.Study Design:A national sample of 1861 US-based adults was surveyed using a validated online survey instrument. The survey was administered by a commercial survey research company. Respondents were randomized to receive a survey about prenatal testing for trisomy 13 and 18 or trisomy 21. Participants were asked to select among testing modalities, including cffDNA testing, and rank the features of testing that they considered most important to decision making.Result:There was substantive interest in the use of cffDNA testing rather than traditional screening mechanisms, with a minority of respondents reporting that they would support the use of both methods in combination. The lower rates of false-negative and false-positive test results and the ability to use the test earlier in the pregnancy were the most highly rated benefits of cffDNA testing. Participants expressed strong support for diagnostic confirmation via invasive testing after a positive result from either screening or cffDNA testing. However, almost one-third of participants reported that they would not endorse the use of either invasive or non-invasive prenatal testing.Conclusion:There appears to be support for uptake of non-invasive prenatal tests. Clinical guidelines should therefore go forward in providing guidance on how to integrate non-invasive methods into the current standard of care. However, our findings indicate that even when accuracy, which is rated by patients as the most important aspect of prenatal testing, is significantly improved over existing screening methods and testing is offered non-invasively, the number of individuals who reported that they would decline any testing remained the same. Attention should therefore be directed at ensuring that the right of informed refusal of prenatal testing is not impacted by new, non-invasive methods.

Focusing on Cause or Cure?: Priorities and Stakeholder Presence in Childhood Psychiatry Research.
AJOB primary research
2014; 5 (1): 44-55
Biomedical research is influenced by many factors, including the involvement of stakeholder groups invested in research outcomes. Stakeholder involvement in research efforts raise questions of justice as their specific interests and motivations play a role in directing research resources that ultimately produce knowledge shaping how different conditions (and affected individuals) are understood and treated by society. This issue is highly relevant to child psychiatry research where diagnostic criteria and treatment strategies are often controversial. Biological similarities and stakeholder differences between attention deficit hyperactivity disorder (ADHD) and autism spectrum disorder (ASD) provide an opportunity to explore this issue by comparing research foci and stakeholder involvement in these conditions.A subset of ADHD and ASD research articles published between 1970-2010 were randomly selected from the PubMed database and coded for research focus, funding source(s), and author-reported conflicts of interest (COIs). Chi-square analyses were performed to identify differences between and within ADHD and ASD research across time.The proportion of ADHD research dedicated to basic, description, and treatment research was roughly similar and remained stable over time, while ASD research showed a significant increase in basic research over the past decade. Government was the primary research funder for both conditions, but for-profit funders were a notable presence in ADHD research, while joint-funding efforts between non-profit and government funders were a notable presence in ASD research. Lastly, COIs were noted more frequently in ADHD than in ASD research.Our study shows significant differences in research foci and funding sources between the conditions, and identifies the specific involvement of for-profit and non-profit groups in ADHD and ASD, respectively. Our findings highlight the relationship between stakeholders outside the research community and research trajectories and suggest that examinations of these relationships must be included in broader considerations of biomedical research ethics.

Reflections on the cost of "low-cost" whole genome sequencing: framing the health policy debate.
2013; 11 (11)
The cost of whole genome sequencing is dropping rapidly. There has been a great deal of enthusiasm about the potential for this technological advance to transform clinical care. Given the interest and significant investment in genomics, this seems an ideal time to consider what the evidence tells us about potential benefits and harms, particularly in the context of health care policy. The scale and pace of adoption of this powerful new technology should be driven by clinical need, clinical evidence, and a commitment to put patients at the centre of health care policy.

Awareness and Acceptable Practices: IRB and Researcher Reflections on the Havasupai Lawsuit.
AJOB primary research
2013; 4 (4): 55-63
In 2003, Havasupai tribe members in Arizona discovered that their DNA samples, collected for genetic studies on Type II diabetes, had been used for studies on schizophrenia, migration, and inbreeding without their approval. The resulting lawsuit brought by the Havasupai reached a settlement in April 2010 in which tribe members received monetary compensation and the return of DNA samples. In this study, we examine the perceptions of Institutional Review Board (IRB) chairpersons and human genetic researchers about the case and its impact on the practice of research.Twenty-minute semi-structured interviews were conducted with 26 Institutional Review Board (IRB) chairs and researchers at six top NIH-funded institutions. Participants were questioned about their knowledge and perceived impact of the Havasupai case and their perceptions of informed consent in genetic research studies.We found that most study participants did not perceive that the Havasupai case had a large impact. However, we identified key concerns and opinions of the case, in particular, increased awareness of culturally sensitive issues with informed consent and secondary uses of samples.The results provide a deeper understanding of how informed consent issues are understood by IRB members and human genetic researchers and the implications for research ethics education.

Ethical, legal, social, and policy implications of behavioral genetics.
Annual review of genomics and human genetics
2013; 14: 515-534
The field of behavioral genetics has engendered a host of moral and social concerns virtually since its inception. The policy implications of a genetic basis for behaviors are widespread and extend beyond the clinic to the socially important realms of education, criminal justice, childbearing, and child rearing. The development of new techniques and analytic approaches, including whole-genome sequencing, noninvasive prenatal genetic testing, and optogenetics, has clearly changed the study of behavioral genetics. However, the social context of biomedical research has also changed profoundly over the past few decades, and in ways that are especially relevant to behavioral genetics. The ever-widening scope of behavioral genetics raises ethical, legal, social, and policy issues in the potential new applications to criminal justice, education, the military, and reproduction. These issues are especially critical to address because of their potentially disproportionate effects on vulnerable populations such as children, the unborn, and the incarcerated. Expected final online publication date for the Annual Review of Genomics and Human Genetics Volume 14 is . Please see http://www.annualreviews.org/catalog/pubdates.aspx for revised estimates.

Best ethical practices for clinicians and laboratories in the provision of noninvasive prenatal testing.
2013; 33 (7): 656-661
OBJECTIVE: The goal of this study is to provide an ethical framework for clinicians and companies providing noninvasive prenatal testing using cell-free fetal DNA or whole fetal cells. METHOD: In collaboration with a National Institutes of Health-supported research ethics consultation committee together with feedback from an interdisciplinary group of clinicians, members of industry, legal experts, and genetic counselors, we developed a set of best practices for the provision of noninvasive prenatal genetic testing. RESULTS: Principal recommendations include the amendment of current informed consent procedures to include attention to the noninvasive nature of new testing and the potential for a broader range of results earlier in the pregnancy. We strongly recommend that tests should only be provided through licensed medical providers and not directly to consumers. CONCLUSION: Prenatal tests, including new methods using cell-free fetal DNA, are not currently regulated by government agencies, and limited professional guidance is available. In the absence of regulation, companies and clinicians should cooperate to adopt responsible best ethical practices in the provision of these tests. © 2013 John Wiley & Sons, Ltd.

Commercial landscape of noninvasive prenatal testing in the United States
2013; 33 (6): 521-531
Cell-free fetal DNA-based noninvasive prenatal testing (NIPT) could significantly change the paradigm of prenatal testing and screening. Intellectual property (IP) and commercialization promise to be important components of the emerging debate about clinical implementation of these technologies. We have assembled information about types of testing, prices, turnaround times, and reimbursement of recently launched commercial tests in the United States from the trade press, news articles, and scientific, legal, and business publications. We also describe the patenting and licensing landscape of technologies underlying these tests and ongoing patent litigation in the United States. Finally, we discuss how IP issues may affect clinical translation of NIPT and their potential implications for stakeholders. Fetal medicine professionals (clinicians and researchers), genetic counselors, insurers, regulators, test developers, and patients may be able to use this information to make informed decisions about clinical implementation of current and emerging noninvasive prenatal tests.

Genetic Counseling for Prenatal Testing: Where is the Discussion About Disability?
JOURNAL OF GENETIC COUNSELING
2012; 21 (6): 814-824
There are little data revealing how genetic counselors talk about disability in the prenatal setting. We performed a qualitative analysis of 93 existing transcripts from simulated patient (SP) genetic counseling sessions conducted in 2003–4 through the Genetic Counseling Video Project. We found that most genetic counselors (95%) focused on the physical aspects of disability while fewer (27%) discussed the social aspects. In addition, few genetic counselors (38%) asked patients about personal experiences with disability. When discussing options available if a pregnancy were diagnosed with a disability, most genetic counselors mentioned termination (86%) while fewer mentioned the continuation of the pregnancy (37%) or adoption (13%). Only half of the genetic counselors asked the SP if she had thought about how she might use the results of prenatal screening. To better facilitate informed decision-making that is consistent with patient values, we recommend genetic counselors engage prenatal patients in a deeper discussion about their ability and willingness to parent a child with a disability.

Cell-free fetal DNA testing for fetal aneuploidy and beyond: clinical integration challenges in the US context
2012; 27 (11): 3123-3131
The recent release of new, non-invasive prenatal tests for fetal aneuploidy using cell-free fetal DNA (cffDNA) has been hailed as a revolution in prenatal testing and has triggered significant commercial interest in the field. Ongoing research portends the arrival of a wide range of cffDNA tests. However, it is not yet clear how these tests will be integrated into well-established prenatal testing strategies in the USA, as the timing of such testing and the degree to which new non-invasive tests will supplement or replace existing screening and diagnostic tools remain uncertain. We argue that there is an urgent need for policy-makers, regulators and professional societies to provide guidance on the most efficient and ethical manner for such tests to be introduced into clinical practice in the USA.

Managing incidental findings and research results in genomic research involving biobanks and archived data sets
GENETICS IN MEDICINE
2012; 14 (4): 361-384
Biobanks and archived data sets collecting samples and data have become crucial engines of genetic and genomic research. Unresolved, however, is what responsibilities biobanks should shoulder to manage incidental findings and individual research results of potential health, reproductive, or personal importance to individual contributors (using "biobank" here to refer both to collections of samples and collections of data). This article reports recommendations from a 2-year project funded by the National Institutes of Health. We analyze the responsibilities involved in managing the return of incidental findings and individual research results in a biobank research system (primary research or collection sites, the biobank itself, and secondary research sites). We suggest that biobanks shoulder significant responsibility for seeing that the biobank research system addresses the return question explicitly. When reidentification of individual contributors is possible, the biobank should work to enable the biobank research system to discharge four core responsibilities to (1) clarify the criteria for evaluating findings and the roster of returnable findings, (2) analyze a particular finding in relation to this, (3) reidentify the individual contributor, and (4) recontact the contributor to offer the finding. We suggest that findings that are analytically valid, reveal an established and substantial risk of a serious health condition, and are clinically actionable should generally be offered to consenting contributors. This article specifies 10 concrete recommendations, addressing new biobanks as well as those already in existence.

Secondary researchers' duties to return incidental findings and individual research results: a partial-entrustment account
GENETICS IN MEDICINE
2012; 14 (4): 467-472
Existing attempts to explain why secondary researchers might have any obligation to return findings to the contributors of genetic samples falter because of the lack of any direct interaction between the secondary researchers and the contributors. The partial-entrustment account of these obligations defended here circumvents this problem by explaining how a chain of special responsibilities can be forged even in the absence of any direct interaction.Genet Med 2012:14(4):467-472.

Human evolutionary genomics: ethical and interpretive issues
TRENDS IN GENETICS
2012; 28 (3): 137-145
Genome-wide computational studies can now identify targets of natural selection. The unique information about humans these studies reveal, and the media attention they attract, indicate the need for caution and precision in communicating results. This need is exacerbated by ways in which evolutionary and genetic considerations have been misapplied to support discriminatory policies, by persistent misconceptions of these fields and by the social sensitivity surrounding discussions of racial ancestry. We discuss the foundations, accomplishments and future directions of human evolutionary genomics, attending to ways in which the interpretation of good science can go awry, and offer suggestions for researchers to prevent misapplication of their work.

Genetic Counseling for Prenatal Testing: Where is the Discussion About Disability?
Journal of genetic counseling
There are little data revealing how genetic counselors talk about disability in the prenatal setting. We performed a qualitative analysis of 93 existing transcripts from simulated patient (SP) genetic counseling sessions conducted in 2003-4 through the Genetic Counseling Video Project. We found that most genetic counselors (95%) focused on the physical aspects of disability while fewer (27%) discussed the social aspects. In addition, few genetic counselors (38%) asked patients about personal experiences with disability. When discussing options available if a pregnancy were diagnosed with a disability, most genetic counselors mentioned termination (86%) while fewer mentioned the continuation of the pregnancy (37%) or adoption (13%). Only half of the genetic counselors asked the SP if she had thought about how she might use the results of prenatal screening. To better facilitate informed decision-making that is consistent with patient values, we recommend genetic counselors engage prenatal patients in a deeper discussion about their ability and willingness to parent a child with a disability.

Cell-free fetal DNA testing: a pilot study of obstetric healthcare provider attitudes toward clinical implementation
2011; 31 (11): 1070-1076
To provide a preliminary assessment of obstetric healthcare provider opinions surrounding implementation of cell-free fetal DNA testing.A 37-question pilot survey was used to address questions around the translation and use of non-invasive prenatal testing using cell-free fetal DNA. The survey was distributed and collected at a Continuing Medical Education course on obstetrics and gynecology.Of 62 survey respondents, 73% were female and 87% held MD/DO degrees. Respondents generally agreed that patients want prenatal diagnostic information to help make decisions about a pregnancy and that cell-free fetal DNA testing would encourage the testing of more patients for more conditions. However, there was an overall lack of knowledge or conviction about using this technology. Genetic counseling and professional society approval were deemed important to implementation, whereas the possibility of direct-to-consumer testing and government regulation produced mixed responses. Respondents indicated that they would be more likely to offer cell-free fetal DNA testing for chromosomal abnormalities and single-gene disorders, but would be cautious with respect to determination of sex and behavioral or late-onset conditions.Preliminary assessment indicates uncertainty among obstetric providers about the details of implementing cell-free fetal DNA testing and suggests expanded research on perspectives of this stakeholder group.

Cell-Free Fetal Nucleic Acid Testing: A Review of the Technology and Its Applications
OBSTETRICAL & GYNECOLOGICAL SURVEY
2011; 66 (7): 431-442
Cell-free fetal nucleic acids circulating in the blood of pregnant women afford the opportunity for early, noninvasive prenatal genetic testing. The predominance of admixed maternal genetic material in circulation demands innovative means for identification and analysis of cell-free fetal DNA and RNA. Techniques using polymerase chain reaction, mass spectrometry, and sequencing have been developed for the purposes of detecting fetal-specific sequences, such as paternally inherited or de novo mutations, or determining allelic balance or chromosome dosage. Clinical applications of these methods include fetal sex determination and blood group typing, which are currently available commercially although not offered routinely in the United States. Other uses of cell-free fetal DNA and RNA being explored are the detection of single-gene disorders, chromosomal abnormalities, and inheritance of parental polymorphisms across the whole fetal genome. The concentration of cell-free fetal DNA may also provide predictive capabilities for pregnancy-associated complications. The roles that cell-free fetal nucleic acid testing assume in the existing framework of prenatal screening and invasive diagnostic testing will depend on factors such as costs, clinical validity and utility, and perceived benefit-risk ratios for different applications. As cell-free fetal DNA and RNA testing continues to be developed and translated, significant ethical, legal, and social questions will arise that will need to be addressed by those with a stake in the use of this technology. Target Audience: Obstetricians & Gynecologists and Family Physicians Learning Objectives: After participating in this activity, physicians should be better able to evaluate techniques and tools for analyzing cell-free fetal nucleic acids, assess clinical applications of prenatal testing, using cell-free fetal nucleic acids and barriers to implementation, and distinguish between relevant clinical features of cell-free fetal nucleic acid testing and existing prenatal genetic screening and diagnostic procedures.

Medical and graduate students' attitudes toward personal genomics
GENETICS IN MEDICINE
2011; 13 (5): 400-408
Medical schools are being approached by direct-to-consumer genotyping companies about genotyping faculty or trainees as a method to "teach" them about the potential implications of genotyping. In thinking about the future incorporation of genotyping into a graduate level genetics course, the purpose of this study was 2-fold: first, to assess knowledge, attitudes, and beliefs of students toward personal genomics as it related to themselves as both as customers and future physicians and as it related to consumers at large, and second, to determine the impact of the course (as taught without genotyping) on knowledge, attitudes, and beliefs.We surveyed first-year medical students and graduate students before and after a core genetics course.After the course, students were less likely to believe that genotyping information would be useful to physicians, patients, or consumers; genotyping would provide information to improve their own personal health; or personal genomic testing services are diagnostic of medical conditions. They were more likely to answer knowledge questions accurately after the course but still had difficulty with clinical interpretation. Despite these changes, a slight majority of students were, and remained, interested in undergoing genotyping themselves. Of note, the number who believed genotyping "would help them understand genetic concepts better than someone else's data" decreased. General curiosity was the most commonly chosen reason for interest in undergoing genotyping, and approximately 50% of respondents expressed concern about confidentiality of results.In conclusion, even without the genotyping process, an educational program about genotyping increased knowledge, particularly about the clinical limitations of genotyping, but student interest in genotyping did not significantly change. Institutions thinking about offering genotyping to their students as part of a learning experience should consider the pros and cons of doing so.

Patently unpatentable: implications of the Myriad court decision on genetic diagnostics
TRENDS IN BIOTECHNOLOGY
2010; 28 (11): 548-551
The recent decision in the case Association for Molecular Pathology et al. v. United States Patent and Trademark Office et al. shocked the biotechnology industry. Although the case could be overturned on appeal, it will probably change how gene patents are written. The effects of the decision might be most strongly felt in the short term by clinical laboratories that develop new genetic tests based on single genes. However, evidence suggests that patents are less effective as an incentive to innovate in the field of genetic diagnostics than for pharmaceuticals. In addition, as genomic technologies move towards whole-genome analysis, policy arguments for patent protection for single genes become less compelling. It is clear that the intellectual property model challenged by the Myriad decision will have to be replaced if new genetic technologies are to achieve their full potential in promoting 'the progress of science and useful arts'.

Research Ethics in the Era of Personalized Medicine: Updating Science's Contract with Society
PUBLIC HEALTH GENOMICS
2010; 13 (6): 378-384
With the completed sequence of the human genome has come the prospect of substantially improving the quality of life for millions through personalized medicine approaches. Still, any advances in this direction require research involving human subjects. For decades science and ethics have enjoyed an allegiance reflected in a common set of ethical principles and procedures guiding the conduct of research with human subjects. Some of these principles emphasize avoiding harm over maximizing benefit. In this paper we revisit the priority given to these ethical principles - particularly the principles that support a cautious approach to science - and propose a reframing of the 'social contract' between science and society that emphasizes reciprocity and meeting public needs.

The "how'' and "whys'' of research: life scientists' views of accountability
JOURNAL OF MEDICAL ETHICS
2009; 35 (12): 762-767
To investigate life scientists' views of accountability and the ethical and societal implications of research.Qualitative focus group and one-on-one interviews.45 Stanford University life scientists, including graduate students, postdoctoral fellows and faculty.Two main themes were identified in participants' discussions of accountability: (1) the "how" of science and (2) the "why" of science. The "how" encompassed the internal conduct of research including attributes such as honesty and independence. The "why," or the motivation for conducting research, was two-tiered: first was the desire to positively impact the research community and science itself, and second was an interest in positively impacting the external community, broadly referred to as society. Participants noted that these motivations were influenced by the current systems of publications, grants and funding, thereby supporting a complex notion of boundary-setting between science and non-science. In addition, while all participants recognised the "how" of science and the two tiers of "why," scientists expressed the need to prioritise these domains of accountability. This prioritisation was related to a researcher's position in the academic career trajectory and to the researcher's subsequent "perceived proximity" to scientific or societal concerns. Our findings therefore suggest the need for institutional change to inculcate early-stage researchers with a broader awareness of the implications of their research. The peer review processes for funding and publication could be effective avenues for encouraging scientists to broaden their views of accountability to society.

Biomedical Scientists' Perceptions of Ethical and Social Implications: Is There a Role for Research Ethics Consultation?
2009; 4 (3)
Research ethics consultation programs are being established with a goal of addressing the ethical, societal, and policy considerations associated with biomedical research. A number of these programs are modelled after clinical ethics consultation services that began to be institutionalized in the 1980s. Our objective was to determine biomedical science researchers' perceived need for and utility of research ethics consultation, through examination of their perceptions of whether they and their institutions faced ethical, social or policy issues (outside those mandated by regulation) and examination of willingness to seek advice in addressing these issues. We conducted telephone interviews and focus groups in 2006 with researchers from Stanford University and a mailed survey in December 2006 to 7 research universities in the U.S.A total of 16 researchers were interviewed (75% response rate), 29 participated in focus groups, and 856 responded to the survey (50% response rate). Approximately half of researchers surveyed (51%) reported that they would find a research ethics consultation service at their institution moderately, very or extremely useful, while over a third (36%) reported that such a service would be useful to them personally. Respondents conducting human subjects research were more likely to find such a service very to extremely useful to them personally than respondents not conducting human subjects research (20% vs 10%; chi(2) p<0.001).Our findings indicate that biomedical researchers do encounter and anticipate encountering ethical and societal questions and concerns and a substantial proportion, especially clinical researchers, would likely use a consultation service if they were aware of it. These findings provide data to inform the development of such consultation programs in general.

Direct-to-consumer genetic tests: beyond medical regulation?
2009; 1 (2): 17-?
The availability of personalized genomic tests, ordered directly by consumers, is rapidly growing. These tests are unlike other genetic or biochemical tests in the sheer amount of data they provide, but interpretation of these genome-wide analyses for health remains uncertain because of the lack of information about environmental and other factors, and because for the vast majority of genetic loci the associations with disease are weak. Although these tests could provide value to customers by offering tools for social networking or genealogy, there are questions about whether and how to regulate these tests and about the extent to which they provide medical information.

Translating genomics into the clinic: moving to the post-Mendelian world.
2009; 1 (1): 7-?
The challenge of genome medicine is not to make a significant move into the clinic over the next five years. The floodgates of genomic research have been opened, and the hopes are that the rising tide will spill over into medical practice in the form of diagnostic tests, risk assessment tools and therapeutics. The ability to perform genome-wide analyses using several different approaches has already provided tantalizing new clues to disease causation and therapeutic targets. Companies have sprung up to use these new technologies to provide information to individuals about predicted health and disease, and about behavioral traits. As exciting as these prospects are, it is far too soon to promise clinically useful information from genomic analyses. We have far to go to assure basic levels of analytical validity or clinical validity of the diagnostic or predictive tools on offer, and to determine their clinical utility in the medical context.

Understanding incidental findings in the context of genetics and genomics
Symposium on Findings in Human Subjects Research - From Imaging to Genomics
WILEY-BLACKWELL PUBLISHING, INC. 2008: 280-?
Human genetic and genomic research can yield information that may be of clinical relevance to the individuals who participate as subjects of the research. It has been common practice among researchers to notify participants during the informed consent process that no individual results will be disclosed, "incidental" or otherwise. However, as genetic information obtained in research becomes orders of magnitude more voluminous, increasingly accessible online, and more informative, this precedent may no longer be appropriate. There is not yet consensus on the responsibilities of researchers to disclose individual research results to research participants. Empirical research suggests that participants want to know individual research results. On the other hand, the increased resolution and power afforded by new genomic analyses may lead to findings of statistical, but not necessarily clinical, significance. This paper addresses the issues to be considered in deciding whether and how to disclose "incidental" findings or other findings of clinical significance that arise in the course of human genomic and genetic research. What research results should be offered, and what should not be offered? For which research should individual results be offered to research participants, when should they be offered, how, and to whom?

Research ethics and the challenge of whole-genome sequencing.
Nature reviews. Genetics
2008; 9 (2): 152-156
The recent completion of the first two individual whole-genome sequences is a research milestone. As personal genome research advances, investigators and international research bodies must ensure ethical research conduct. We identify three major ethical considerations that have been implicated in whole-genome research: the return of research results to participants; the obligations, if any, that are owed to participants' relatives; and the future use of samples and data taken for whole-genome sequencing. Although the issues are not new, we discuss their implications for personal genomics and provide recommendations for appropriate management in the context of research involving individual whole-genome sequencing.

Practical approaches to incidental findings in brain imaging research
2008; 70 (5): 384-390
A decade of empirical work in brain imaging, genomics, and other areas of research has yielded new knowledge about the frequency of incidental findings, investigator responsibility, and risks and benefits of disclosure. Straightforward guidance for handling such findings of possible clinical significance, however, has been elusive. In early work focusing on imaging studies of the brain, we suggested that investigators and institutional review boards must anticipate and articulate plans for handling incidental findings. Here we provide a detailed analysis of different approaches to the problem and evaluate their merits in the context of the goals and setting of the research and the involvement of neurologists, radiologists, and other physicians. Protecting subject welfare and privacy, as well as ensuring scientific integrity, are the highest priorities in making choices about how to handle incidental findings. Forethought and clarity will enable these goals without overburdening research conducted within or outside the medical setting.

Strangers at the Benchside: Research ethics consultation
AMERICAN JOURNAL OF BIOETHICS
2008; 8 (3): 4-13
Institutional ethics consultation services for biomedical scientists have begun to proliferate, especially for clinical researchers. We discuss several models of ethics consultation and describe a team-based approach used at Stanford University in the context of these models. As research ethics consultation services expand, there are many unresolved questions that need to be addressed, including what the scope, composition, and purpose of such services should be, whether core competencies for consultants can and should be defined, and how conflicts of interest should be mitigated. We make preliminary recommendations for the structure and process of research ethics consultation, based on our initial experiences in a pilot program.

Ethical implications of array comparative genomic hybridization in complex phenotypes: points to consider in research
GENETICS IN MEDICINE
2007; 9 (9): 626-631
As with many new diagnostic technologies, the recent rapid emergence of array comparative genome hybridization in clinical genetics provides the power to observe new biological phenomena before their clinical significance is well understood. This raises ethical issues for clinicians when applying the technologies. However, at this early stage of research and development on array comparative genome hybridization, the ethical implications of the conduct of research, as well as how research findings are presented and interpreted, should also be considered by the research, clinical, and ethics communities. These considerations are especially important in the use of array comparative genome hybridization to study complex and common traits. We examined recent publications on autism as an example of the application of array comparative genome hybridization to a complex phenotype. Our goal was to identify points to consider for researchers, clinicians, and patients/families to ensure responsible and ethical design, presentation, and interpretation of these kinds of studies.

Race and ethnicity in genetic research
AMERICAN JOURNAL OF MEDICAL GENETICS PART A
2007; 143A (9): 961-970
Use of race and ethnicity terms in genetic research continues to generate controversy. Despite differing opinions about their basis or relevance, there is some agreement that investigators using these terms should: explain why the terms or categories were used, define them carefully, and apply them consistently. An important question is whether these recommendations are reflected in practice. Here we addressed this question based on 330 randomly selected articles published between 2001 and 2004 that reported on genetic research and used one or more words from a defined list of race, ethnicity, or population terms. The recommendation that authors using race or ethnicity terms explain the basis for assigning them to study populations was met infrequently (9.1%), and articles that used race and ethnicity as variables were no more likely than those that used them only to label a sample to provide these details. No article defined or discussed the concepts of race or ethnicity. With limited exceptions, current practice does not reflect repeated recommendations for using race or ethnicity terms in genetic research. This study provides a baseline against which to measure future trends.

Racial and ethnic categories in biomedical research: There is no baby in the bathwater
Conference on Proposals for the Responsible Use of Racial and Ethnic Categories in Biomedical Research
WILEY-BLACKWELL. 2006: 497-?
The use of racial categories in biomedicine has had a long history in the United States. However, social hierarchy and discrimination, justified by purported scientific differences, has also plagued the history of racial categories. Because "race" has some correlation with biological and genetic characteristics, there has been a call not to "throw the baby out with the bathwater" by eliminating race as a research or clinical category. I argue that race is too undefined and fluid to be useful as a proxy for biology or genetics.

ELSI priorities for brain imaging
AMERICAN JOURNAL OF BIOETHICS
2006; 6 (2): W24-W31
As one of the most compelling technologies for imaging the brain, functional MRI (fMRI) produces measurements and persuasive pictures of research subjects making cognitive judgments and even reasoning through difficult moral decisions. Even after centuries of studying the link between brain and behavior, this capability presents a number of novel significant questions. For example, what are the implications of biologizing human experience? How might neuroimaging disrupt the mysteries of human nature, spirituality, and personal identity? Rather than waiting for an ethical agenda to emerge from some unpredictable combination of the concerns of ethicists and researchers, the attention of journalists, or after controversy is sparked by research that cannot be retracted, we queried key figures in bioethics and the humanities, neuroscience, media, industry, and patient advocacy in focus groups and interviews. We identified specific ethical, legal and social issues (ELSI) that highlight researcher obligations and the nonclinical impact of the technology at this new frontier.

What is in a cause? Exploring the relationship between genetic cause and felt stigma
GENETICS IN MEDICINE
2006; 8 (1): 33-42
Concern over stigma as a consequence of genetic testing has grown in response to the recent increase in genetic research and testing resulting from the Human Genome Project. However, whether a genetic or hereditary basis necessarily confers a stigma to a condition remains unexamined.We performed a qualitative interview study with 86 individuals with one of four conditions: deafness or hearing loss, breast cancer, sickle cell disease, and cystic fibrosis. The first two groups were divided approximately between people who ascribed their conditions to a genetic or hereditary cause and those who did not.Respondents interpreted genetic or hereditary causes and nongenetic causes in a variety of ways. Subjects with breast cancer reported the most consistently negative interpretation of genetic cause. This response concerned future ill health, not an enduring sense of stigma. Deaf and hard of hearing subjects provided the most consistently positive comments about a genetic or hereditary basis to their condition, casting familial hearing loss as a vital component of group and individual identity. Respondents with sickle cell disease and cystic fibrosis offered similar and positive interpretations of the genetic cause of their condition insofar as it meant their conditions were not contagious.Although some subjects report feeling stigmatized as a result of their condition, this stigmatization is not uniformly associated with the condition's cause, genetic or otherwise. Instead, stigma emerges from a variety of sources in the context of the lived experience of a particular condition.

What are gene patents and why are people worried about them?
2005; 8 (4): 203-208
This article examines what it means to patent a gene. Numerous ethical concerns have been raised about the effects of such patents on clinical medical practice as well as on research and development. We describe what kinds of inventions are covered by human gene patents, give several examples and summarize the small body of empirical research performed in the US examining the effects of these patents. There is little evidence that early fears about gene patenting placing substantial restraints on research and clinical medicine have come to fruition. Nonetheless, there are areas of concern, and policy makers, physicians and the public should be alert to ensure that the net social benefits of patenting human genes are maintained.

Forensic genetics and ethical, legal and social implications beyond the clinic
2004; 36 (11): S8-S12
Data on human genetic variation help scientists to understand human origins, susceptibility to illness and genetic causes of disease. Destructive episodes in the history of genetic research make it crucial to consider the ethical and social implications of research in genomics, especially human genetic variation. The analysis of ethical, legal and social implications should be integrated into genetic research, with the participation of scientists who can anticipate and monitor the full range of possible applications of the research from the earliest stages. The design and implementation of research directs the ways in which its results can be used, and data and technology, rather than ethical considerations or social needs, drive the use of science in unintended ways. Here we examine forensic genetics and argue that all geneticists should anticipate the ethical and social issues associated with nonmedical applications of genetic variation research.

Genetic research and health disparities
JAMA-JOURNAL OF THE AMERICAN MEDICAL ASSOCIATION
2004; 291 (24): 2985-2989
Alleviating health disparities in the United States is a goal with broad support. Medical research undertaken to achieve this goal typically adopts the well-established perspective that racial discrimination and poverty are the major contributors to unequal health status. However, the suggestion is increasingly made that genetic research also has a significant role to play in alleviating this problem, which likely overstates the importance of genetics as a factor in health disparities. Overemphasis on genetics as a major explanatory factor in health disparities could lead researchers to miss factors that contribute to disparities more substantially and may also reinforce racial stereotyping, which may contribute to disparities in the first place. Arguments that promote genetics research as a way to help alleviate health disparities are augmented by several factors, including research funding initiatives and the distinct demographic patterns of health disparities in the United States.

Financial conflict-of-interest policies in clinical research: Issues for clinical investigators
2003; 78 (8): 769-774
As industry sponsorship of clinical research grows, investigators' personal financial relationships with those sponsors are under increasing scrutiny. The federal government, some states, and many universities have enacted conflict-of-interest policies to monitor and regulate investigators' financial relationships. Little is known, however, about investigators' awareness of or support for these policies or their attitudes toward regulatory efforts. To explore the possible implications of conflict-of-interest policies for clinical researchers, the authors interviewed active clinical investigators at two institutions where the conflict-of-interest policies differ. The most striking feature of the interviews was the range of perceptions and attitudes expressed by clinical investigators and their implications for administrators, professional societies, and policymakers concerned with conflicts of interest. Fewer than half of the interviewed investigators could accurately describe their campus' conflict-of-interest policy. Many investigators felt that professional societies, the public, and individual investigators were appropriate monitors of conflicts of interest. Many investigators recognized the general risks associated with conflicts of interest, but felt that they personally were not at risk. A fundamental challenge facing administrators and policymakers is to demonstrate to all investigators, both clinical and nonclinical, that the potential for bias, pressure and conflict is relevant to all investigators with industry relationships.

Privacy issues in personalized medicine
2003; 4 (2): 107-112
Pharmacogenomics is the emerging study of why individuals respond differently to drugs. It aims to replace the current 'one size fits all' therapeutic approach with 'personalized medicine' that will use pharmacogenomic tests to predict drug response. In a simple conceptualization, these tests challenge privacy as a result of two factors: how comprehensive is the test and how is the access to samples or digital information controlled. Point-of-care tests are likely to be limited in scope, fit seamlessly into medical records and do not raise qualitatively new ethical and privacy challenges. In order to define practically relevant pharmacogenomic predictive patterns however, large-scale clinical trials and research on human specimens will be required, resulting in large databases of genomic information. The genomic scans' magnitude, stability, implications to kin and ease of dissemination together represent a qualitatively different challenge compared to traditional, self-limited and often temporally transient medical information.

Effects of patents and licenses on the provision of clinical genetic testing services
JOURNAL OF MOLECULAR DIAGNOSTICS
2003; 5 (1): 3-8
The growth of patents that include genetic sequences has been accompanied by concern about their impact on the ability of physicians to provide clinical genetic testing services and to perform research. Therefore, we conducted a survey of clinical laboratory directors that perform DNA-based genetic tests to examine potential effects. We performed a telephone survey between July and September in 2001 of all laboratory directors in the United States who were members of the Association for Molecular Pathology or who were listed on the GENETESTS:org website. One hundred thirty-two of 211 (63%) laboratory directors were interviewed. Ten of these were excluded because they did not conduct DNA-based genetic tests. Almost all performed genetic tests for clinical purposes. Half performed tests for research purposes as well. Twenty-five percent of respondents reported that they had stopped performing a clinical genetic test because of a patent or license. Fifty-three percent of respondents reported deciding not to develop a new clinical genetic test because of a patent or license. In total, respondents were prevented from performing 12 genetic tests, and all of these tests were among those performed by a large number of laboratories. We found 22 patents that were relevant to the performance of these 12 tests. Fifteen of the 22 patents (68%) are held by universities or research institutes, and 13 of the 22 patents (59%) were based on research funded by the United States Government. Overall, respondents reported that their perceptions of the effects of patents on the cost, access, and development of genetic tests, or data sharing among researchers, were negative. In contrast, most respondents felt that patents did not have an effect on the quality of testing. We conclude that patents and licenses have had a significant effect on the ability of clinical laboratories to develop and provide genetic tests. Furthermore, our findings suggest that clinical geneticists feel that their research is inhibited by patents. The effects of patents and licenses on patients' access to tests, and the costs and quality thereof, remains to be determined.

Conflicts of interest in magnetic resonance imaging: issues in clinical practice and research.
Topics in magnetic resonance imaging
2002; 13 (2): 73-77
In the use of magnetic resonance imaging (MRI) in medicine and in the conduct of MRI research, conflicts of interest are routinely generated. These conflicts are not necessarily unique to MRI and are not necessarily considered malpractice or misconduct. It is important, however, for clinicians and researchers to understand what constitutes a conflict of interest and how to mitigate the potential adverse effects of those conflicts on patients and on the integrity of research. It also is important for medical professionals to understand the changes in the clinical and research environments that make conflicts of interest more prevalent and more of a concern to policy makers. Finally, it is important for medical professionals who work with MRI to understand some of the characteristics of MRI that might increase the prevalence of conflicts of interest in clinical practice and research.

Protecting subjects' interests in genetics research
AMERICAN JOURNAL OF HUMAN GENETICS
2002; 70 (4): 965-971
Biomedical researchers often assume that sponsors, subjects, families, and disease-associated advocacy groups contribute to research solely because of altruism. This view fails to capture the diverse interests of many participants in the emerging research enterprise. In the past two decades, patient groups have become increasingly active in the promotion and facilitation of genetics research. Simultaneously, a significant shift of academic biomedical science toward commercialization has occurred, spurred by U.S. federal policy changes. The concurrent rise in both the roles that subjects play and the commercial interests they have presents numerous ethical challenges. We examine the interests of different research participants, finding that these interests are not addressed by current policies and practices. We conclude that all participants should be given a voice in decisions affecting ownership, access to, and use of commercialized products and services, and that researchers and institutions should negotiate issues relating to control of research results and the sharing of benefits before the research is performed.

Patenting human genetic material: refocusing the debate
NATURE REVIEWS GENETICS
2000; 1 (3): 227-231
The biotechnology industry has become firmly established over the past twenty years and gene patents have played an important part in this phenomenon. However, concerns have been raised over the patentability of human genetic material, through public protests and international statements, but to little effect. Here we discuss some of these concerns, the patent authorities' response to them, and ways in which to address these issues and to move the debate forward using current legal structures.

Policies on faculty conflicts of interest at US universities
JAMA-JOURNAL OF THE AMERICAN MEDICAL ASSOCIATION
2000; 284 (17): 2203-2208
Despite federal regulations on faculty conflicts of interest in federally funded research, academic-industry ties are common, and evidence exists that financial considerations bias the research record. Public scrutiny of these ties is increasing, especially in cases where researchers have financial interests in the corporate sponsors of their clinical research.To review policies on conflict of interest at major biomedical research institutions in the United States.Cross-sectional survey and content analysis study conducted from August 1998 to February 2000.The 100 US institutions with the most funding from the National Institutes of Health in 1998 were initially sampled; policies from 89 institutions were available and included in the analysis.Process for disclosure, review, and management of conflicts of interest and specified management strategies or limitations, according to the institutions' faculty/staff conflict of interest policies.Content of the conflict of interest policies varied widely across institutions. Fifty-five percent of policies (n = 49) required disclosures from all faculty while 45% (n = 40) required them only from principal investigators or those conducting research. Nineteen percent of policies (n = 17) specified limits on faculty financial interests in corporate sponsors of research, 12% (n = 11) specified limits on permissible delays in publication, and 4% (n = 4) prohibited student involvement in work sponsored by a company in which the faculty mentor had a financial interest.Most policies on conflict of interest in our sample of major research institutions in the United States lack specificity about the kinds of relationships with industry that are permitted or prohibited. Wide variation in management of conflicts of interest among institutions may cause unnecessary confusion among potential industrial partners or competition among universities for corporate sponsorship that could erode academic standards. It is in the long-term interest of institutions to develop widely agreed-on, clear, specific, and credible policies on conflicts of interest. JAMA. 2000;284:2203-2208.

Commercialization of BRCA1/2 testing: Practitioner awareness and use of a new genetic test
AMERICAN JOURNAL OF MEDICAL GENETICS
1999; 83 (3): 157-163
It was our purpose to determine the characteristics of practitioners in the United States who were among the first to inquire about and use the BRCA1 and BRCA2 (BRCA1/2) genetic tests outside of a research protocol. Questionnaires were mailed to all practitioners who requested information on or ordered a BRCA1/2 test from the University of Pennsylvania (UPenn) Genetic Diagnostics Laboratory (GDL) between October 1, 1995 and January 1, 1997 (the first 15 months the test was available for clinical use). The response rate was 67% of practitioners; 54% (121/225) were genetic counselors, 39% (87/225) were physicians or lab directors. Most physicians were oncologists, pathologists, or obstetrician/gynecologists, but 20% practiced surgery or internal or general medicine. Fifty-six percent (125/225) had ordered a BRCA1/2 test for a patient; most of the rest had offered or were willing to offer testing. Of those who had offered testing, 70% had a patient decline BRCA1/2 testing when offered. Practitioners perceived that patients' fear of loss of confidentiality was a major reason for declining. Nearly 60% of practitioners reported that their patients had access to a genetic counselor, but 28% of physicians who ordered a BRCA1/2 test reported having no such access, despite the GDL's counseling requirement. The proportion of physicians reporting no access to genetic counselors for their patients increased from 22.4% in the first half of the study to 50% in the last half. Many practitioners have an interest in BRCA1/2 testing, despite policy statements that discourage its use outside of research protocols. Practitioner responses suggest that patient interest in testing seems to be tempered by knowledge of potential risks. An apparent increase in patient concern about confidentiality and inability to pay for testing could indicate growing barriers to testing. Although most practitioners reported having access to counseling facilities, perceived lack of such access among an increasing proportion of practitioners indicates that lab requirements for counseling are difficult to enforce and suggests that an increasing proportion of patients may not be getting access to counseling.

Does masking author identity improve peer review quality? - A randomized controlled trial
3rd International Congress on Peer Review in Biomedical Publication
AMER MEDICAL ASSOC. 1998: 240–42
All authors may not be equal in the eyes of reviewers. Specifically, well-known authors may receive less objective (poorer quality) reviews. One study at a single journal found a small improvement in review quality when reviewers were masked to author identity.To determine whether masking reviewers to author identity is generally associated with higher quality of review at biomedical journals, and to determine the success of routine masking techniques.A randomized controlled trial performed on external reviews of manuscripts submitted to Annals of Emergency Medicine, Annals of Internal Medicine, JAMA, Obstetrics & Gynecology, and Ophthalmology.Two peers reviewed each manuscript. In one study arm, both peer reviewers received the manuscript according to usual masking practice. In the other arm, one reviewer was randomized to receive a manuscript with author identity masked, and the other reviewer received an unmasked manuscript.Review quality on a 5-point Likert scale as judged by manuscript author and editor. A difference of 0.5 or greater was considered important.A total of 118 manuscripts were randomized, 26 to usual practice and 92 to intervention. In the intervention arm, editor quality assessment was complete for 77 (84%) of 92 manuscripts. Author quality assessment was complete on 40 (54%) of 74 manuscripts. Authors and editors perceived no significant difference in quality between masked (mean difference, 0.1; 95% confidence interval [CI], -0.2 to 0.4) and unmasked (mean difference, -0.1; 95% CI, -0.5 to 0.4) reviews. We also found no difference in the degree to which the review influenced the editorial decision (mean difference, -0.1; 95% CI,-0.3 to 0.3). Masking was often unsuccessful (overall, 68% successfully masked; 95% CI, 58%-77%), although 1 journal had significantly better masking success than others (90% successfully masked; 95% CI, 73%-98%). Manuscripts by generally known authors were less likely to be successfully masked (odds ratio, 0.3; 95% CI, 0.1-0.8). When analysis was restricted to manuscripts that were successfully masked, review quality as assessed by editors and authors still did not differ.Masking reviewers to author identity as commonly practiced does not improve quality of reviews. Since manuscripts of well-known authors are more difficult to mask, and those manuscripts may be more likely to benefit from masking, the inability to mask reviewers to the identity of well-known authors may have contributed to the lack of effect.

Masking author identity in peer review - What factors influence masking success?
3rd International Congress on Peer Review in Biomedical Publication
AMER MEDICAL ASSOC. 1998: 243–45
In a previous study, we found that masking success was higher at a journal that masked reviewers to author identity. We hypothesized that masking policy or other factors could be associated with masking success.To evaluate differences in success of masking reviewers to author identity at 7 biomedical journals and to identify factors associated with these differences.Written questionnaire.Reviewers at 3 journals with a long-standing policy of masking author identity (Annals of Emergency Medicine, Epidemiology, and Journal of the American Geriatrics Society) and 4 journals without a policy of masking author identity (Annals of Internal Medicine, JAMA, Obstetrics & Gynecology, and Ophthalmology).Masking success (percentage of reviewers successfully masked) and reviewer characteristics associated with masking.There was no significant difference in masking success between journals with a policy of masking (60%) and those without (58%) (P= .92). We found no association between masking success and a policy of masking when adjusted for the reviewer characteristics of age, sex, years of reviewing experience, number of articles published, number of articles reviewed, percentage of time spent in research, editorial experience, or academic rank (odds ratio [OR], 1.3; 95% confidence interval [CI], 0.64-2.8; P=.43). In multivariable analysis of reviewer characteristics, reviewers spending a greater percentage of time in research, the only significant predictor of masking success, were less likely to be successfully masked (OR, 1.01; 95% CI, 1.00-1.02) (P=.04).Masking success appears unrelated to a journal policy of masking, but is associated with reviewers' research experience and could be affected by other characteristics. Using reviewers with less research and reviewing experience might increase masking success, but the effect on review quality is unknown.

Educational material about genetic tests: Does it provide key information for patients and practitioners?
AMERICAN JOURNAL OF MEDICAL GENETICS
1997; 73 (3): 314-320
Genetic testing for common conditions will be used increasingly in primary care, but resources for patient counseling are decreasing. It is also necessary that primary care practitioners be better equipped to do basic genetic counseling. Therefore, the quality of informational materials for practitioners and patients is important. It was unknown how often key elements recommended by policy groups were actually included in such material. It was our aim to determine the content of printed informational material for practitioners and patients on genetic testing. We performed (1) a telephone survey of organizations in the United States that developed genetic tests or services and (2) a content analysis of pamphlets obtained from these organizations to determine the presence of 10 critical elements necessary to evaluate the appropriateness and performance of the tests. Almost 95% (169/178) of organizations responded to our survey; 131/169 (78%) reported using informational materials. We analyzed 115 pamphlets collected from 125/131 (95%) organizations. Elements least frequently included in the pamphlets were risks and benefits, patient rights, and intended use or purpose of the test. Most frequently included were descriptions of the conditions detected by the test, and the appropriate patients for testing. Nearly one half of the pamphlets included some statement about the accuracy of the test, but most of these did not specify whether their statements referred to sensitivity, specificity, or predictive value. Overall, pamphlets tended to contain information that would aid in determining a patient's eligibility for a genetic test, but did not contain sufficient information about the tests themselves. Our results suggest that several critical elements need to be added to enhance informed choices by patients and physicians.

To compare the quality, relevance, and structure of drug studies published in symposium proceedings that are sponsored by drug companies with 1) articles from symposia with other sponsors and 2) articles in the peer-reviewed parent journals of symposium proceedings; and to study the relation between drug company sponsorship and study outcome.Cross-sectional studies of clinical drug studies published in symposium proceedings or their parent medical journals.The proportion of articles with no methods sections (which are necessary to assess quality); methodologic quality and clinical relevance scores; and the proportion of articles with outcomes favoring the drug of interest.Symposia sponsored by single drug companies had more articles without methods sections (10%; 108 of 1064) than did symposia that had other sponsors (3%; 58 of 2314) or symposia that had no mentioned sponsor (2%; 29 of 1663) (P < 0.001). The mean methodologic quality and relevance scores of articles were similar both by type of sponsorship and between articles published in symposia sponsored by single drug companies and articles from the parent journals. Significantly more articles with drug company support (98%; 39 of 40) than without drug company support (79%; 89 of 112) had outcomes favoring the drug of interest (P = 0.01).Articles in symposia sponsored by single drug companies were similar in quality and clinical relevance to articles with other sponsors and to articles published in the parent journals. Articles with drug company support are more likely than articles without drug company support to have outcomes favoring the drug of interest.

FAST MYOSIN HEAVY-CHAINS EXPRESSED IN SECONDARY MAMMALIAN MUSCLE-FIBERS AT THE TIME OF THEIR INCEPTION
JOURNAL OF CELL SCIENCE
1994; 107: 2361-2371
Mammalian skeletal muscle is generated by two waves of fiber formation, resulting in primary and secondary fibers. These fibers mature to give rise to several classes of adult muscle fibers with distinct contractile properties. Here we describe fast myosin heavy chain (MyHC) isoforms that are expressed in nascent secondary, but not primary, fibers in the early development of rat and human muscle. These fast MyHCs are distinct from previously described embryonic and neonatal fast MyHCs. To identify these MyHCs, monoclonal antibodies were used whose specificity was determined in western blots of MyHCs on denaturing gels and reactivity with muscle tissue at various stages of development. To facilitate a comparison of our results with those of others obtained using different antibodies or species, we have identified cDNAs that encode the epitopes recognized by our antibodies wherever possible. The results suggest that epitopes characteristic of adult fast MyHCs are expressed very early in muscle fiber development and distinguish newly formed secondary fibers from primary fibers. This marker of secondary fibers, which is detectable at the time of their inception, should prove useful in future studies of the derivation of primary and secondary fibers in mammalian muscle development.

INSTRUMENTS FOR ASSESSING THE QUALITY OF DRUG STUDIES PUBLISHED IN THE MEDICAL LITERATURE
2nd International Congress on Peer Review in Biomedical Publication
AMER MEDICAL ASSOC. 1994: 101–4
To develop valid and reliable instruments to assess the methodologic quality and clinical relevance of drug studies.We developed an instrument to assess the methodologic quality of articles reporting clinical research and an instrument to measure nonmethodologic measures of quality, such as clinical relevance, generalizability, and adherence to ethical standards. Each instrument was pretested by seven independent, masked reviewers and modified based on interrater agreement and content validity of individual items. We determined correlational validity of the final methodologic quality instrument by comparing quality scores assigned to 10 articles by means of our instrument and a previously published one.Clinical drug studies published in symposium proceedings and peer reviewed biomedical literature.Interrater reliability of overall quality scores, measured by intraclass correlation (r) and Kendall's coefficient of concordance (W), and interrater reliability of individual items, by percentage agreement.The interrater reliability of the pretest methodologic quality instrument was high (r = .89 [95% confidence interval, .73 to .96]; W = 0.64). Correlational validity of the final instrument was suggested by the high degree of concordance with another previously published one (W = 0.74). The interrater reliability of the pretest clinical relevance instrument was moderate (r = .41 [95% confidence interval, .18 to .64]; W = 0.47). Reviewers confirmed the content validity of both instruments.The two instruments we developed, one measuring methodologic quality and one measuring clinical relevance of articles reporting clinical research, are reliable, valid, and applicable to a variety of research designs.

3 SLOW MYOSIN HEAVY-CHAINS SEQUENTIALLY EXPRESSED IN DEVELOPING MAMMALIAN SKELETAL-MUSCLE
1993; 158 (1): 183-199
Myosin heavy chain (MyHC) isoforms show a striking diversity of expression patterns during mammalian development. Using a set of monoclonal antibodies that recognize different epitopes on myosin heavy chain isoforms we show that there exist in human and rat skeletal muscle at least three isoforms of slow twitch myosin heavy chain. To facilitate a comparison of our results to others obtained using different antibodies or species, we have identified cDNAs encoding the epitopes recognized by the three slow antibodies. Using these reagents, we show that the onset of expression of three slow MyHC isoforms is temporally distinct during early gestation. This result suggests that a sequence of MyHC transitions plays an important role in determining muscle fiber function at fetal, neonatal, and adult stages.

EVIDENCE FOR MYOBLAST-EXTRINSIC REGULATION OF SLOW MYOSIN HEAVY-CHAIN EXPRESSION DURING MUSCLE-FIBER FORMATION IN EMBRYONIC-DEVELOPMENT
JOURNAL OF CELL BIOLOGY
1993; 121 (4): 795-810
Vertebrate muscles are composed of an array of diverse fast and slow fiber types with different contractile properties. Differences among fibers in fast and slow MyHC expression could be due to extrinsic factors that act on the differentiated myofibers. Alternatively, the mononucleate myoblasts that fuse to form multinucleated muscle fibers could differ intrinsically due to lineage. To distinguish between these possibilities, we determined whether the changes in proportion of slow fibers were attributable to inherent differences in myoblasts. The proportion of fibers expressing slow myosin heavy chain (MyHC) was found to change markedly with time during embryonic and fetal human limb development. During the first trimester, a maximum of 75% of fibers expressed slow MyHC. Thereafter, new fibers formed which did not express this MyHC, so that the proportion of fibers expressing slow MyHC dropped to approximately 3% of the total by midgestation. Several weeks later, a subset of the new fibers began to express slow MyHC and from week 30 of gestation through adulthood, approximately 50% of fibers were slow. However, each myoblast clone (n = 2,119) derived from muscle tissues at six stages of human development (weeks 7, 9, 16, and 22 of gestation, 2 mo after birth and adult) expressed slow MyHC upon differentiation. We conclude from these results that the control of slow MyHC expression in vivo during muscle fiber formation in embryonic development is largely extrinsic to the myoblast. By contrast, human myoblast clones from the same samples differed in their expression of embryonic and neonatal MyHCs, in agreement with studies in other species, and this difference was shown to be stably heritable. Even after 25 population doublings in tissue culture, embryonic stage myoblasts did not give rise to myoblasts capable of expressing MyHCs typical of neonatal stages, indicating that stage-specific differences are not under the control of a division dependent mechanism, or intrinsic "clock." Taken together, these results suggest that, unlike embryonic and neonatal MyHCs, the expression of slow MyHC in vivo at different developmental stages during gestation is not the result of commitment to a distinct myoblast lineage, but is largely determined by the environment.

BETA-ENOLASE IS A MARKER OF HUMAN MYOBLAST HETEROGENEITY PRIOR TO DIFFERENTIATION
1992; 151 (2): 626-629
In this report, we define a muscle-specific marker, beta-enolase, that distinguishes proliferating myoblasts from different stages of development. Enolase exists as multiple isoforms and in the course of cardiac and skeletal muscle development the beta isoform progressively replaces the alpha isoform. In skeletal muscle, this change in gene expression, unlike most developmental changes in myogenic gene expression, is evident in undifferentiated myoblasts. Whereas myoblasts from fetal tissues express alpha-enolase mRNA, beta-enolase is the predominant mRNA expressed by myoblasts from postnatal tissues. Our results are consistent with the idea that distinct precursor myoblasts contribute to the diversity of fiber types characteristic of muscle tissue at different stages of development.
