Dyadic Yoga For Head And Neck Cancer Patients Undergoing Chemoradiation And Their Family Caregivers, Kathrin Milbury, David I Rosenthal, Yisheng Li, An Thuy Ngo-Huang, Smitha Mallaiah, Sania Yousuf, Clifton D Fuller, Carol Lewis, Eduardo Bruera, Lorenzo Cohen

Faculty, Staff and Student Publications

Objectives: Concurrent chemoradiation to treat head and neck cancer (HNC) may result in debilitating toxicities. Targeted exercise such as yoga therapy may buffer against treatment-related sequelae; thus, this pilot RCT examined the feasibility and preliminary efficacy of a yoga intervention. Because family caregivers report low caregiving efficacy and elevated levels of distress, we included them in this trial as active study participants.

Methods: HNC patients and their caregivers were randomized to a 15-session dyadic yoga program or a waitlist control (WLC) group. Prior to randomization, patients completed standard symptom (MDASI-HN) and patients and caregivers completed quality of life (SF-36) assessments. …

A Qualitative Interview Study To Determine Barriers And Facilitators Of Implementing Automated Decision Support Tools For Genomic Data Access, Vasiliki Rahimzadeh, Jinyoung Baek, Jonathan Lawson, Edward S Dove

Center for Medical Ethics and Health Policy Staff Publications

Data access committees (DAC) gatekeep access to secured genomic and related health datasets yet are challenged to keep pace with the rising volume and complexity of data generation. Automated decision support (ADS) systems have been shown to support consistency, compliance, and coordination of data access review decisions. However, we lack understanding of how DAC members perceive the value add of ADS, if any, on the quality and effectiveness of their reviews. In this qualitative study, we report findings from 13 semi-structured interviews with DAC members from around the world to identify relevant barriers and facilitators to implementing ADS for genomic …

Inclusion Of Adoption As A Pregnancy Management Option In Prenatal Genetic Counseling Practice, Emma Billings

Dissertations and Theses (Open Access)

Prenatal genetic counselors are essential to providing education, psychosocial support, and guidance on pregnancy options to patients who receive a fetal diagnosis of an anomaly or genetic condition. Therefore, genetic counselors should be well-educated on comprehensive pregnancy management options consisting of parenting, abortion, and adoption. The landscape of adoption education in genetic counseling practice was last characterized in 2010 by Perry and Henry, revealing substantial variability in both the inclusion of adoption-specific education in genetic counseling program (GCP) curricula and the discussion of pregnancy options with patients in prenatal practice. As a result, the authors published a call to action …

Center for Medical Ethics and Health Policy Staff Publications

Importance: Polygenic embryo screening (PES) is a novel technology that estimates the likelihood of developing future conditions (eg, diabetes or depression) and traits (eg, height or cognitive ability) in human embryos, with the goal of selecting which embryos to use. Given its commercial availability and concerns raised by researchers, clinicians, bioethicists, and professional organizations, it is essential to inform key stakeholders and relevant policymakers about the public's perspectives on this technology.

Objective: To survey US adults to examine general attitudes, interests, and concerns regarding PES use.

Design, setting, and participants: For this survey study, data were collected from 1 stratified …

Patient Interest In And Clinician Reservations On Polygenic Embryo Screening: A Qualitative Study Of Stakeholder Perspectives, D Barlevy, I Cenolli, T Campbell, R Furrer, M Mukherjee, K Kostick-Quenet, S Carmi, T Lencz, G Lázaro-Muñoz, S Pereira

Center for Medical Ethics and Health Policy Staff Publications

Purpose: We explored and compared perspectives of reproductive endocrinology and infertility specialists (REIs) and in vitro fertilization (IVF) patients regarding polygenic embryo screening (PES), a new type of preimplantation screening that estimates the genetic chances of developing polygenic conditions and traits in the future.

Methods: Qualitative thematic analysis of semi-structured interviews with US-based REIs and IVF patients.

Results: Clinicians and patients often held favorable views of screening embryos for physical or psychiatric conditions, though clinicians tended to temper their positive attitudes with specific caveats. Clinicians also expressed negative views about screening embryos for traits more frequently than patients, who generally …

Methods: Semi-structured interviews with (1) investigators conducting FTLD research that includes genetic data collection and/or analysis and (2) participants enrolled in a single site longitudinal FTLD study.

Results: Analysis of the interviews identified three meta themes: perspectives on data sharing, experiences with enrollment and participation, and data management and security as …

Achieving Procedural Parity In Managing Access To Genomic And Related Health Data: A Global Survey Of Data Access Committee Members, Jonathan Lawson, Vasiliki Rahimzadeh, Jinyoung Baek, Edward S Dove

Center for Medical Ethics and Health Policy Staff Publications

Data access committees (DACs) are critical players in the data sharing ecosystem. DACs review requests for access to data held in one or more repositories and where specific constraints determine how the data may be used and by whom. Our team surveyed DAC members affiliated with genomic data repositories worldwide to understand standard processes and procedures, operational metrics, bottlenecks, and efficiencies, as well as their perspectives on possible improvements to quality review. We found that DAC operations and systemic issues were common across repositories globally. In general, DAC members endeavored to achieve an appropriate balance of review efficiency, quality, and …

Investigating The Roles And Responsibilities Of Institutional Signing Officials After Data Sharing Policy Reform For Federally Funded Research In The United States: National Survey, Jinyoung Baek, Jonathan Lawson, Vasiliki Rahimzadeh

Center for Medical Ethics and Health Policy Staff Publications

Background: New federal policies along with rapid growth in data generation, storage, and analysis tools are together driving scientific data sharing in the United States. At the same, triangulating human research data from diverse sources can also create situations where data are used for future research in ways that individuals and communities may consider objectionable. Institutional gatekeepers, namely, signing officials (SOs), are therefore at the helm of compliant management and sharing of human data for research. Of those with data governance responsibilities, SOs most often serve as signatories for investigators who deposit, access, and share research data between institutions. Although …

Opportunities And Challenges For The Use Of Deep Brain Stimulation In The Treatment Of Refractory Major Depression, Prashin Unadkat, Joao Quevedo, Jair Soares, Albert Fenoy

Faculty, Staff and Student Publications

Major Depressive Disorder continues to remain one of the most prevalent psychiatric diseases globally. Despite multiple trials of conventional therapies, a subset of patients fail to have adequate benefit to treatment. Deep brain stimulation (DBS) is a promising treatment in this difficult to treat population and has shown strong antidepressant effects across multiple cohorts. Nearly two decades of work have provided insights into the potential for chronic focal stimulation in precise brain targets to modulate pathological brain circuits that are implicated in the pathogenesis of depression. In this paper we review the rationale that prompted the selection of various brain …

Building Effective Mentoring Relationships During Clinical Ethics Fellowships: Pedagogy, Programs, And People, Trevor M Bibler, Ryan H Nelson, Bryanna Moore, Janet Malek, Mary A Majumder

Center for Medical Ethics and Health Policy Staff Publications

How should clinical ethicists be trained? Scholars have stated that clinical ethics fellowships create well-trained, competent ethicists. While this appears intuitive, few features of fellowship programs have been publicly discussed, let alone debated. In this paper, we examine how fellowships can foster effective mentoring relationships. These relationships provide the foundation for the fellow's transition from novice to competent professional. In this essay, we begin by discussing our pedagogical commitments. Next, we describe the structures our program has created to assist our fellows in becoming competent ethicists. We then outline the kinds of knowledge, skills, and professional attributes mentors should possess. …

Early use of genome sequencing (GS) in the diagnostic odyssey can reduce suffering and improve care, but questions remain about which patient populations are most amenable to GS as a first-line diagnostic test. To address this, the Medical Genome Initiative conducted a literature review to identify appropriate clinical indications for GS. Studies published from January 2011 to August 2022 that reported on the diagnostic yield (DY) or clinical utility of GS were included. An exploratory meta-analysis using a random effects model evaluated DY based on cohort size and diagnosed cases per cohort. Seventy-one studies met inclusion criteria, comprising over 13,000 …

The Ddhd2-Stxbp1 Interaction Mediates Long-Term Memory Via Generation Of Saturated Free Fatty Acids, Isaac O Akefe, Saber H Saber, Benjamin Matthews, Bharat G Venkatesh, Rachel S Gormal, Daniel G Blackmore, Suzy Alexander, Emma Sieriecki, Yann Gambin, Jesus Bertran-Gonzalez, Nicolas Vitale, Yann Humeau, Arnaud Gaudin, Sevannah A Ellis, Alysee A Michaels, Mingshan Xue, Benjamin Cravatt, Merja Joensuu, Tristan P Wallis, Frédéric A Meunier

The phospholipid and free fatty acid (FFA) composition of neuronal membranes plays a crucial role in learning and memory, but the mechanisms through which neuronal activity affects the brain's lipid landscape remain largely unexplored. The levels of saturated FFAs, particularly of myristic acid (C14:0), strongly increase during neuronal stimulation and memory acquisition, suggesting the involvement of phospholipase A1 (PLA1) activity in synaptic plasticity. Here, we show that genetic ablation of the PLA1 isoform DDHD2 in mice dramatically reduces saturated FFA responses to memory acquisition across the brain. Furthermore, DDHD2 loss also decreases memory performance in reward-based learning and spatial memory …

Mendelian randomization has been widely used to assess the causal effect of a heritable exposure variable on an outcome of interest, using genetic variants as instrumental variables. In practice, data on the exposure variable can be incomplete due to high cost of measurement and technical limits of detection. In this paper, we propose a valid and efficient method to handle both unmeasured and undetectable values of the exposure variable in one-sample Mendelian randomization analysis with individual-level data. We estimate the causal effect of the exposure variable on the outcome using maximum likelihood estimation and develop an expectation maximization algorithm for …

International Consensus On Sleep Problems In Pediatric Palliative Care: Paving The Way, Anna Mercante, Judith Owens, Oliviero Bruni, Magda L. Nunes, Paul Gringras, Shirley Xin Li, Simonetta Papa, Ulrika Kreicbergs, Joanne Wolfe, Boris Zernikow, Ana Lacerda, Franca Benini, Pediatric Sleep And Palliative Care Group

Journal Articles: Munroe-Meyer Institute

OBJECTIVE: Sleep problems constitute a common and heterogeneous complaint in pediatric palliative care (PPC), where they often contribute to disease morbidity and cause additional distress to children and adolescents and their families already facing the burden of life-threatening and life-limiting conditions. Despite the significant impact of sleep problems, clinical evidence is lacking. The application of general pediatric sleep recommendations appears insufficient to address the unique challenges of the PPC dimension in terms of disease variability, duration, comorbidities, complexity of needs, and particular features of sleep problems related to hospice care. Therefore, we initiated an international project aimed at establishing a …

Perspectives From Cystinosis: Access To Healthcare May Be A Confounding Factor For Variant Classification, Chen-Han Wilfred Wu, Alicja Tomaszewski, Louisa Stark, Fernando Scaglia, Ewa Elenberg, Fredrick R Schumaker

Faculty, Staff and Students Publications

Genetic variability persists across diverse populations, and it may impact the characterization of heritable diseases in different ancestral groups. Cystinosis is a metabolic disease caused by pathogenic variants in the CTNS gene causing the cellular accumulation of cystine. We attempted to assess the currently poorly characterized prevalence of cystinosis by employing a population genetics methodology. However, we encountered a significant challenge due to genetic variations across different populations, and the consideration of potential disparities in access to healthcare made our results inconclusive. Pathogenic CTNS variants were identified in a representative global population cohort using The Human Gene Mutation Database (HGMD) …

The Relationship Of Neighborhood Disadvantage, Biological Aging, And Psychosocial Risk And Resilience Factors In Heart Failure Incidence Among Black Persons: A Moderated Mediation Analysis, Ganga S Bey, James R Pike, Anthony S Zannas, Qian Xiao, Bing Yu, Amil M Shah, Priya Palta

Faculty, Staff and Student Publications

Objectives: Deprived living environments contribute to greater heart failure (HF) risk among non-Hispanic Black persons, who disproportionately occupy disadvantaged neighborhoods. The mechanisms for these effects are not fully explicated, partially attributable to an insufficient understanding of the individual factors that contribute additional risk or resilience to the impact of neighborhood disadvantage on health. The objective of this study was, therefore, to clarify the complex pathways over which such exposures act to facilitate more targeted, effective interventions. Given the evidence for a mediating role of biological age and a moderating role of individual psychosocial characteristics in the neighborhood disadvantage-HF link, we …

An Ewas Of Dementia Biomarkers And Their Associations With Age, African Ancestry, And Ptsd, Mark W. Miller, Erika J. Wolf, Xiang Zhao, Mark W. Logue, Sage E. Hawn

Psychology Faculty Publications

Background

Large-scale cohort and epidemiological studies suggest that PTSD confers risk for dementia in later life but the biological mechanisms underlying this association remain unknown. This study examined this question by assessing the influences of PTSD, APOE ε4 genotypes, DNA methylation, and other variables on the age- and dementia-associated biomarkers Aβ40, Aβ42, GFAP, NfL, and pTau-181 measured in plasma. Our primary hypothesis was that PTSD would be associated with elevated levels of these markers.

Methods

Analyses were based on data from a PTSD-enriched cohort of 849 individuals. We began by performing factor analyses of the biomarkers, the results of which …

Aims: Health care transition (HCT) to adult care and young adult disease self-management is a multi-step process involving three major stakeholders - the adolescent, the caregiver, and the provider. Preparation gaps exist within each of these stakeholder groups. This paper presents the development of the Intervention to Promote Autonomy and Competence in Transition-aged Youth (IPACT), a multi-level (adolescent, caregiver, provider), multi-modal (interactive skill building sessions, educational materials, videos) intervention to address gaps in all three stakeholder groups simultaneously and help support achieving the three core elements of HCT planning.

Methods: Eight processes were utilized to develop the IPACT intervention, including …

Public Perspectives On Investigative Genetic Genealogy: Findings From A National Focus Group Study, Jacklyn Dahlquist, Jill O Robinson, Amira Daoud, Whitney Bash-Brooks, Amy L Mcguire, Christi J Guerrini, Stephanie M Fullerton

Center for Medical Ethics and Health Policy Staff Publications

Background: Investigative genetic genealogy (IGG) is a technique that involves uploading genotypes developed from perpetrator DNA left at a crime scene, or DNA from unidentified remains, to public genetic genealogy databases to identify genetic relatives and, through the creation of a family tree, the individual who was the source of the DNA. As policymakers demonstrate interest in regulating IGG, it is important to understand public perspectives on IGG to determine whether proposed policies are aligned with public attitudes.

Methods: We conducted eight focus groups with members of the public (N = 72), sampled from four geographically diverse US regions, …

As the federal government continues to expand upon and improve its data sharing policies over the past 20 years, complex challenges remain. Our interviews with U.S. academic genetic researchers (n=23) found that the burden, translation, industry limitations, and consent structure of data sharing remain major governance challenges.

Interrogating The Value Of Return Of Results For Diverse Populations: Perspectives From Precision Medicine Researchers, Caitlin E Mcmahon, Nicole Foti, Melanie Jeske, William R Britton, Stephanie M Fullerton, Janet K Shim, Sandra Soo-Jin Lee

Center for Medical Ethics and Health Policy Staff Publications

Background: Over the last decade, the return of results (ROR) in precision medicine research (PMR) has become increasingly routine. Calls for individual rights to research results have extended the "duty to report" from clinically useful genetic information to traits and ancestry results. ROR has thus been reframed as inherently beneficial to research participants, without a needed focus on who benefits and how. This paper addresses this gap, particularly in the context of PMR aimed at increasing participant diversity, by providing investigator and researcher perspectives on and questions about the assumed value of ROR in PMR.

Methods: Semi-structured interviews with a …

Choosing Your “Healthiest” Embryo After Dobbs: Polygenic Screening And Distinctive Challenges For Truth In Advertising And Informed Consent, Dov Fox, Sonia Suter, Meghna Mukherjee, Stacey Pereira, Gabriel Lázaro-Muñoz

Center for Medical Ethics and Health Policy Staff Publications

Polygenic embryo screening ("PES") analyzes embryos for hundreds or thousands of genomic loci to generate risk scores that estimate genetic susceptibility to conditions and traits compared to the general population. The technology is commercially marketed directly to consumers. Companies focus mostly on medical conditions, sometimes in ways that oversell its advantages and efficacy, encouraging fertility patients to "choose your healthiest embryo" and "protect your future child from genetic risks." The advertising of PES trades on norms of children's health and good parenting and reinforces those normative ideals. While it is easy to assume PES will be constrained in practice by …
