Returning Individual Research Results from Digital Phenotyping in Psychiatry.

Psychiatry is rapidly adopting digital phenotyping and artificial intelligence/machine learning tools to study mental illness based on tracking participants' locations, online activity, phone and text message usage, heart rate, sleep, physical activity, and more. Existing ethical frameworks for return of individual research results (IRRs) are inadequate to guide researchers for when, if, and how to return this unprecedented number of potentially sensitive results about each participant's real-world behavior. To address this gap, we convened an interdisciplinary expert working group, supported by a National Institute of Mental Health grant. Building on established guidelines and the emerging norm of returning results in participant-centered research, we present a novel framework specific to the ethical, legal, and social implications of returning IRRs in digital phenotyping research. Our framework offers researchers, clinicians, and Institutional Review Boards (IRBs) urgently needed guidance, and the principles developed here in the context of psychiatry will be readily adaptable to other therapeutic areas.

Returning incidentally discovered Hepatitis C RNA-seq results to COPDGene study participants.

The consequences of returning infectious pathogen test results identified incidentally in research studies have not been well-studied. Concerns include identification of an important health issue for individuals, accuracy of research test results, public health impact, potential emotional distress for participants, and need for IRB permissions. Blood RNA-sequencing analysis for non-human RNA in 3984 participants from the COPDGene study identified 228 participants with evidence suggestive for hepatitis C virus (HCV) infection. We hypothesized that incidentally discovered HCV results could be effectively returned to COPDGene participants with attention to the identified concerns. In conjunction with a COPDGene Participant Advisory Panel, we developed and obtained IRB approval for a process of returning HCV research results and an HCV Follow-Up Study questionnaire to capture information about previous HCV diagnosis and treatment information and participant reactions to return of HCV results. During phone calls following the initial HCV notification letter, 84 of 124 participants who could be contacted (67.7%) volunteered that they had been previously diagnosed with HCV infection. Thirty-one of these 124 COPDGene participants were enrolled in the HCV Follow-Up Study. Five of the 31 HCV Follow-Up Study participants did not report a previous diagnosis of HCV. For four of these participants, subsequent clinical HCV testing confirmed HCV infection. Thus, 30/31 Follow-Up Study participants had confirmed HCV diagnoses, supporting the accuracy of the HCV research test results. However, the limited number of participants in the Follow-Up Study precludes an accurate assessment of the false-positive and false-negative rates of the research RNA sequencing evidence for HCV. Most HCV Follow-Up Study participants (29/31) were supportive of returning HCV research results, and most participants found the process for returning HCV results to be informative and not upsetting. Newly diagnosed participants were more likely to be pleased to learn about a potentially curable infection (p = 0.027) and showed a trend toward being more frightened by the potential health risks of HCV (p = 0.11). We conclude that HCV results identified incidentally during transcriptomic research studies can be successfully returned to research study participants with a carefully designed process.

Clarifying the Ethics and Oversight of Chimeric Research.

This article is the lead piece in a special report that presents the results of a bioethical investigation into chimeric research, which involves the insertion of human cells into nonhuman animals and nonhuman animal embryos, including into their brains. Rapid scientific developments in this field may advance knowledge and could lead to new therapies for humans. They also reveal the conceptual, ethical, and procedural limitations of existing ethics guidance for human-nonhuman chimeric research. Led by bioethics researchers working closely with an interdisciplinary work group, the investigation focused on generating conceptual clarity and identifying improvements to governance approaches, with the goal of helping scholars, funders, scientists, institutional leaders, and oversight bodies (embryonic stem cell research oversight [ESCRO] committees and institutional animal care and use committees [IACUCs]) deliver principled and trustworthy oversight of this area of science. The article, which focuses on human-nonhuman animal chimeric research that is stem cell based, identifies key ethical issues in and offers ten recommendations regarding the ethics and oversight of this research. Turning from bioethics' previous focus on human-centered questions about the ethics of "humanization" and this research's potential impact on concepts like human dignity, this article emphasizes the importance of nonhuman animal welfare concerns in chimeric research and argues for less-siloed governance and oversight and more-comprehensive public communication.

Responding to signals of mental and behavioral health risk in pragmatic clinical trials: Ethical obligations in a healthcare ecosystem.

BACKGROUND: Ethical responsibilities for monitoring and responding to signals of behavioral and mental health risk (such as suicidal ideation, opioid use disorder, or depression) in general clinical research have been described; however, pragmatic clinical trials (PCTs) raise new contextual challenges. METHODS: We use our experience with the PRISM (Pragmatic and Implementation Studies for the Management of Pain to Reduce Opioid Prescribing) program, which is a component of the Helping End Addiction Long-Term (HEAL) Initiative, to provide examples of research studying nonpharmacologic interventions for pain that collect sensitive data. Members of the PRISM Ethics and Regulatory Core and Patient-Centered Outcome Core Working Group discussed and refined considerations and recommendations. RESULTS: PCT researchers can help identify the extent of their ethical obligations to monitor and respond to signals of potential behavioral and mental health risks by understanding and aligning stakeholder expectations; considering characteristics of the trial and study population; defining triggers, thresholds, and responsibilities for action; identifying appropriate response mechanisms and capabilities; integrating responses with health systems; and addressing privacy. Based on such an assessment, researchers should proactively identify if, when, and how a response will be triggered. Doing so necessitates that stakeholders understand their roles in managing such risks. Finally, consent forms and other study disclosures should clearly state what if any responses might be taken. CONCLUSION: Early and ongoing bi-directional communication with relevant stakeholders is critical to identifying and meeting the ethical challenges for PCTs when managing and responding to behavioral and mental health data that potentially signal elevated risk to individuals.

Expert Perspectives on Oversight for Unregulated mHealth Research: Empirical Data and Commentary.

In qualitative interviews with a diverse group of experts, the vast majority believed unregulated researchers should seek out independent oversight. Reasons included the need for objectivity, protecting app users from research risks, and consistency in standards for the ethical conduct of research. Concerns included burdening minimal risk research and limitations in current systems of oversight. Literature and analysis supports the use of IRBs even when not required by regulations, and the need for evidence-based improvements in IRB processes.

Skin cancer multiplicity in lung transplant recipients: a prospective population-based study.

BACKGROUND: Lung transplant recipients are at high risk of skin cancer, but precise annual incidence rates of treated skin cancers per patient are unknown. OBJECTIVES: To perform a prospective assessment of the total burden of histologically confirmed squamous cell carcinoma (SCC) and basal cell carcinoma (BCC) and associated factors in lung transplant recipients. METHODS: A population-based cohort of 125 Queensland lung transplant recipients aged 18 years and over, recruited between 2013 and 2015, were followed to the end of 2016. All underwent dermatological skin examinations at baseline and annually thereafter and patients self-reported all interim treated skin cancers, which were verified against pathology databases. Standard skin cancer risk factors were obtained via questionnaire, and details of medications were acquired from hospital records. RESULTS: During a median follow-up time of 1·7 years, 29 (23%) and 30 (24%) lung transplant recipients with a median duration of immunosuppression of 3·3 years developed SCC and BCC, respectively. The general population age-standardized incidence rates of SCC and BCC were 201 and 171 per 1000 person-years, respectively (based on first primary SCC or BCC during follow-up); however, on accounting for multiple primary tumours, corresponding incidence rates were 447 and 281 per 1000 person-years. Risk of multiple SCCs increased around sixfold in those aged ≥ 60 years and in those with previous skin cancer, and increased around threefold in those treated with the antifungal medication voriconazole. Multiple BCC risk rose threefold from age 60 years and tenfold for patients with previous skin cancer. CONCLUSIONS: Lung transplant recipients have very high incidence of multiple primary skin cancers. Close surveillance and assiduous prevention measures are essential.

Indoor hospital air and the impact of ventilation on bioaerosols: a systematic review.

Healthcare-acquired infections (HAIs) continue to persist in hospitals, despite the use of increasingly strict infection-control precautions. Opportunistic airborne transmission of potentially pathogenic bioaerosols may be one possible reason for this persistence. Therefore, this study aimed to systematically review the concentrations and compositions of indoor bioaerosols in different areas within hospitals and the effects of different ventilation systems. Electronic databases (Medline and Web of Science) were searched to identify articles of interest. The search was restricted to articles published from 2000 to 2017 in English. Aggregate data was used to examine the differences in mean colony forming units per cubic metre (cfu/m3) between different hospital areas and ventilation types. A total of 36 journal articles met the eligibility criteria. The mean total bioaerosol concentrations in the different areas of the hospitals were highest in the inpatient facilities (77 cfu/m3, 95% confidence interval (CI): 55-108) compared with the restricted (13cfu/m3, 95% CI: 10-15) and public areas (14 cfu/m3, 95% CI: 10-19). Hospital areas with natural ventilation had the highest total bioaerosol concentrations (201 cfu/m3, 95% CI: 135-300) compared with areas using conventional mechanical ventilation systems (20 cfu/m3, 95% CI: 16-24). Hospital areas using sophisticated mechanical ventilation systems (such as increased air changes per hour, directional flow and filtration systems) had the lowest total bioaerosol concentrations (9 cfu/m3, 95% CI: 7-13). Operating sophisticated mechanical ventilation systems in hospitals contributes to improved indoor air quality within hospitals, which assists in reducing the risk of airborne transmission of HAIs.

Time since intercourse (TSI) data from a large-scale casework study of penile-vaginal penetration allegations using Sperm Elution​™.

Time since intercourse (TSI) expectations are dependent on the method used to recover spermatozoa from vaginal swabs. TSI data following Sperm Elution™ is presented from a large scale study of 2269 cases of penile-vaginal penetration sexual assault allegations analysed by Cellmark Forensic Services and is compared to published TSI data generated using two different water-based elution methods Sperm Elution recovered spermatozoa in 32% of cases analysed where the alleged offence had occurred 3-4 days previously, significantly above the level detected using other elution methods. The improvements afforded by Sperm Elution in the ability to generate clearly distinguishable male DNA profiles from samples containing low levels of spermatozoa, and the recovery of further spermatozoa from swabs previously subjected to water-based elution methods are also discussed.

Clinical comparison of actinic changes preceding squamous cell carcinoma vs. intraepidermal carcinoma in renal transplant recipients.

Intraepidermal carcinoma (IEC) is a type of in situ squamous cell carcinoma (SCC), although progression of IEC is rare. We sought to investigate differences between the actinic skin changes preceding the development of both SCC and IEC. Photographs of 63 skin sites at which either SCC or IEC subsequently developed in 37 renal transplant recipients (RTRs) were examined for features of actinic change. We found that areas of skin with an actinic keratosis (AK) > 1 cm2 in size were four times more likely to develop SCC as opposed to IEC (OR = 4.42; 95% CI 1.25-15.60). Skin sites with ≥ 25% of the area affected by AK were again four times more likely to develop SCC than IEC. These results highlight the scale of visible actinic damage required for development of SCC compared with IEC, emphasizing the importance of treating areas of skin with marked visible actinic change to reduce SCC risk in RTRs.

The Final Rule: When the Rubber Meets the Road.

The Common Rule originally issued in 1991 and last amended in 2005 is scheduled to be replaced on January 19, 2018 by a revised Common Rule (the final rule). The goal of the revisions is to modernize and improve applicability of the rule to a research landscape that has dramatically changed since 1991. Translating these changes into action will require comprehensive understanding of the final rule and detailed implementation planning by Human Research Protection Programs. This paper presents select changes that require substantial attention; including for example: expansion of the exempt category, changes to continuing review requirements, changes to the informed consent form and the use of single IRBs for domestic multi-site research. In addition, myriad policies, procedures and workflows will have to be developed, drastically rewritten, or just mildly tweaked.

Actinic keratosis-related signs predictive of squamous cell carcinoma in renal transplant recipients: a nested case-control study.

BACKGROUND: Squamous cell carcinoma (SCC) and intraepidermal carcinoma (IEC) commonly arise in actinically damaged skin. OBJECTIVES: To identify clinical features of actinic change that correlate with an increased risk of SCC or IEC in the short-to-medium term as guidance for prioritizing field treatment. METHODS: In a nested case-control study, cases were renal transplant recipients who developed an incident SCC or IEC within 18 months following baseline examination and photography. Controls without SCC or IEC were matched to cases on age, sex and duration of immunosuppression. Predefined skin sites on the head, neck and upper limbs were examined using baseline photographs to assess objectively the following features of actinic damage: presence of actinic keratosis (AK) patch (defined as AK > 1 cm2 ), number of AK patches, number of AKs and area affected by AK. Odds ratios (ORs) and 95% confidence intervals (CIs) were calculated using McNemar's test to identify differences in SCC/IEC risk combined and SCC risk alone between case and control skin sites. RESULTS: Thirty-nine cases were matched to 39 controls. Significant associations with the presence of an AK patch, number of AK patches, number of AKs and area affected by AKs were identified. The presence of an AK patch conferred an 18-fold increased risk of SCC (OR 18·00, 95% CI 2·84-750) and more than a sixfold increased risk of SCC/IEC combined (OR 6·60, 95% CI 2·56-21·66). CONCLUSIONS: AK patches are predictive of SCC/IEC development within 18 months. This can be used to guide site selection for field treatment in patients with widespread actinic damage.

Implementation of Electronic Consent at a Biobank: An Opportunity for Precision Medicine Research.

The purpose of this study is to characterize the potential benefits and challenges of electronic informed consent (eIC) as a strategy for rapidly expanding the reach of large biobanks while reducing costs and potentially enhancing participant engagement. The Partners HealthCare Biobank (Partners Biobank) implemented eIC tools and processes to complement traditional recruitment strategies in June 2014. Since then, the Partners Biobank has rigorously collected and tracked a variety of metrics relating to this novel recruitment method. From June 2014 through January 2016, the Partners Biobank sent email invitations to 184,387 patients at Massachusetts General Hospital and Brigham and Women's Hospital. During the same time period, 7078 patients provided their consent via eIC. The rate of consent of emailed patients was 3.5%, and the rate of consent of patients who log into the eIC website at Partners Biobank was 30%. Banking of biospecimens linked to electronic health records has become a critical element of genomic research and a foundation for the NIH's Precision Medicine Initiative (PMI). eIC is a feasible and potentially game-changing strategy for these large research studies that depend on patient recruitment.

Removal versus retention of asymptomatic third molars in mandibular angle fractures: a randomized controlled trial.

The treatment dilemma provided by asymptomatic third molars in mandibular angle fractures remains controversial. This prospective randomized controlled trial was undertaken to determine whether there is an advantage to extraction or retention of the third molar whilst repairing a mandibular angle fracture. Sixty-four patients were allocated randomly to the two treatment groups. All underwent open reduction and internal fixation (ORIF) with standard postoperative care. The primary outcome measure was uncomplicated fracture healing. Secondary measures were surgical duration, malocclusion, wound healing, nerve injury, and return to theatre. All patients had uncomplicated fracture healing. The incidence of nerve injury was 16% for the retention group compared with 39% for the removal group (P=0.038). The average operating time for ORIF and third molar retention cases was 58.5min and for ORIF and third molar removal cases was 66.3min (P=0.26). There was no statistically significant difference between groups for wound healing, occlusion outcomes, or return to theatre. Given the additional risk of nerve injury and the additional operating time required for removal of a third molar, in the absence of an absolute indicator for removal of the third molar, it appears justifiable to advise retaining the tooth in the line of a mandibular angle fracture.

Returning a Research Participant's Genomic Results to Relatives: Analysis and Recommendations.

Genomic research results and incidental findings with health implications for a research participant are of potential interest not only to the participant, but also to the participant's family. Yet investigators lack guidance on return of results to relatives, including after the participant's death. In this paper, a national working group offers consensus analysis and recommendations, including an ethical framework to guide investigators in managing this challenging issue, before and after the participant's death.

Return of Genetic Research Results to Participants and Families: IRB Perspectives and Roles.

We surveyed IRB chairs' perspectives on offering individual genetic research results to participants and families, including family members of deceased participants, and the IRB's role in addressing these issues. Given a particular hypothetical scenario, respondents favored offering results to participants but not family members, giving choices at the time of initial consent, and honoring elicited choices. They felt IRBs should have authority regarding the process issues, but a more limited role in medical and scientific issues.

Canadian Research Ethics Board Leadership Attitudes to the Return of Genetic Research Results to Individuals and Their Families.

Genomic research may uncover results that have direct actionable benefit to the individual. An emerging debate is the degree to which researchers may have responsibility to offer results to the biological relatives of the research participant. In a companion study to one carried out in the United States, we describe the attitudes of Canadian Research Ethics Board (REB) chairs to this issue and their opinions as to the role of the REB in developing related policy.

Harmonization and streamlining of research oversight for pragmatic clinical trials.

The oversight of research involving human participants is a complex process that requires institutional review board review as well as multiple non-institutional review board institutional reviews. This multifaceted process is particularly challenging for multisite research when each site independently completes all required local reviews. The lack of inter-institutional standardization can result in different review outcomes for the same protocol, which can delay study operations from start-up to study completion. Hence, there have been strong calls to harmonize and thus streamline the research oversight process. Although the institutional review board is only one of the required reviews, it is often identified as the target for harmonization and streamlining. Data regarding variability in decision-making and interpretation of the regulations across institutional review boards have led to a perception that variability among institutional review boards is a primary contributor to the problems with review of multisite research. In response, many researchers and policymakers have proposed the use of a single institutional review board of record, also called a central institutional review board, as an important remedy. While this proposal has merit, the use of a central institutional review board for multisite research does not address the larger problem of completing non-institutional review board institutional review in addition to institutional review board review­and coordinating the interdependence of these reviews. In this article, we describe the overall research oversight process, distinguish between institutional review board and institutional responsibilities, and identify challenges and opportunities for harmonization and streamlining. We focus on procedural and organizational issues and presume that the protection of human subjects remains the paramount concern. Suggested modifications of institutional review board processes that focus on time, efficiency, and consistency of review must also address what effect such changes have on the quality of review. We acknowledge that assessment of quality is difficult in that quality metrics for institutional review board review remain elusive. At best, we may be able to assess the time it takes to review protocols and the consistency across institutions.
