Impact of barriers and motivators on intention and confidence to undergo hereditary cancer genetic testing.

Genetic testing for hereditary cancer syndromes can provide lifesaving information allowing for individualized cancer screening, prevention, and treatment. However, the determinants, both barriers and motivators, of genetic testing intention are not well described. A survey of barriers and motivators to genetic testing was emailed to adult patients eligible for genetic testing based on cancer diagnosis who previously have not had genetic testing (n = 201). Associations between barriers/motivators with testing intention and confidence were examined first by correlation followed by multivariable linear regression model holding constant potential covariates. Seven barrier items from two domains (logistics and genetic testing knowledge) were found to significantly negatively correlate with genetic testing intention. Unexpectedly, three barrier items had significant positive correlation with genetic testing intention; these were related to family worry (passing a condition on to future generations) and testing knowledge (needing more information on the genetic testing process and what it has to offer). Ten barrier items had significant negative correlation with confidence to get a genetic test and encompassed four domains: stigma, insurance/genetic discrimination, knowledge, and cost. All motivator items were associated with intention to get a genetic test, while none were associated with confidence. Multivariable analysis yielded six total barriers (five from the knowledge domain, one from cost domain) and two motivators (relieved to know and treatment impact) that were significantly associated with genetic testing intention or confidence when controlling for demographic characteristics. These findings indicate the need for tailored interventions to amplify motivating factors and counter-message barriers to enhance patient motivation and confidence to undergo testing.

Family Recall of and Response to Germline Pathologic Variants Found on Paired Tumor-Germline Sequencing in Pediatric Oncology.

PURPOSE: Paired tumor-germline sequencing can identify somatic variants for targeted therapy and germline pathogenic variants (GPVs) causative of hereditary cancer/tumor predisposition syndromes. It is unknown how patients/families in pediatric oncology use information about an identified GPV. We assessed recall of germline results and actions taken on the basis of findings. METHODS: We completed phone surveys with patients (and/or their parent) with GPVs identified via a single academic medical center's paired tumor-germline sequencing study. Seven hundred forty pediatric (aged 0-25 years) oncology patients were enrolled in this sequencing study between May 2012 and August 2021. Ninety-six participants (13.0%) had at least one GPV identified and were therefore eligible for this survey. The parent/guardian (for patients younger than 18 years or deceased patients) or patients themselves (if 18 years or older) were contacted. Survey topics included germline result recall, experience with genetic counseling, changes to patient's cancer treatment/screening, sharing of results with family members, and lifestyle changes. RESULTS: Fifty-three surveys (response rate, 55.2%) were completed between October 2021 and June 2022. Thirty-seven (69.8%) respondents correctly recalled the identified GPV. Discussing results with a genetic counselor (P = .0001), having a GPV related to the cancer/tumor diagnosis (P = .002), and non-Hispanic White race/ethnicity (P = .02) were associated with accurate recall. Twenty-five respondents (47.2%) reported a change in the child's cancer treatment and/or screening recommendations, 17 respondents (32.1%) made a lifestyle change on the basis of the results, and 44 respondents (83.0%) shared results with at least one family member. CONCLUSION: While most respondents remembered that a GPV was identified in the patient, some did not recall having a GPV found, and others recalled germline findings incorrectly. Future work may determine patient/family preferences for timing/method of result return to optimize patient recall and use of germline results.

Parents' judgments of children's gender-typed play indicate qualities of the early-life caregiving environment.

Play is critical for children's development but is the target of significant gender stereotyping. Early in life, parents must navigate these stereotypes on behalf of their children. This study examined typologies of caregivers' judgments toward their infants' future engagement with toys and activities considered typical of same- and different-gender peers, and whether these judgments indicated qualities of the child-rearing environment. We conducted a latent profile analysis on a sample of 501 families with infant children in a large city in the Western United States (501 mothers, 388 fathers; 69% White, 16% Latinx, 8% African American). Results showed that parents could be classified as androgynous, stereotyped, counterstereotyped, or gender-impartial in their preferences for their child's toys and activities. Mothers who displayed androgynous and counterstereotyped preferences-primarily conveying approval different-gender-typed play-were rated higher on objective assessments of the quality of the home environment and parent-child interactions. How parents orient to cultural gendered messages for children's play may have implications for the overall parenting environment. We discuss implications for research and practice.

Psychosocial factors impacting barriers and motivators to cancer genetic testing.

BACKGROUND: Only a small proportion of patients who qualify for clinical genetic testing for cancer susceptibility get testing. Many patient-level barriers contribute to low uptake. In this study, we examined self-reported patient barriers and motivators for cancer genetic testing. METHODS: A survey comprised of both new and existing measures related to barriers and motivators to genetic testing was emailed to patients with a diagnosis of cancer at a large academic medical center. Patients who self-reported receiving a genetic test were included in these analyses (n = 376). Responses about emotions following testing as well as barriers and motivators prior to getting testing were examined. Group differences in barriers and motivators by patient demographic characteristics were examined. RESULTS: Being assigned female at birth was associated with increased emotional, insurance, and family concerns as well as increased health benefits compared to patients assigned male at birth. Younger respondents had significantly higher emotional and family concerns compared to older respondents. Recently diagnosed respondents expressed fewer concerns about insurance implications and emotional concerns. Those with a BRCA-related cancer had higher scores on social and interpersonal concerns scale than those with other cancers. Participants with higher depression scores indicated increased emotional, social and interpersonal, and family concerns. CONCLUSIONS: Self-reported depression emerged as the most consistent factor influencing report of barriers to genetic testing. By incorporating mental health resources into clinical practice, oncologists may better identify those patients who might need more assistance following through with a referral for genetic testing and the response afterwards.

The Michigan Genetic Hereditary Testing (MiGHT) study's innovative approaches to promote uptake of clinical genetic testing among cancer patients: a study protocol for a 3-arm randomized controlled trial.

BACKGROUND: Although most cancers are sporadic, germline genetic variants are implicated in 5-10% of cancer cases. Clinical genetic testing identifies pathogenic germline genetic variants for hereditary cancers. The Michigan Genetic Hereditary Testing (MiGHT) study is a three-arm randomized clinical trial that aims to test the efficacy of two patient-level behavioral interventions on uptake of cancer genetic testing. METHODS: The two interventions being tested are (1) a virtual genetics navigator and (2) motivational interviewing by genetic health coaches. Eligible participants are adults with a diagnosis of breast, prostate, endometrial, ovarian, colorectal, or pancreatic cancer who meet the National Comprehensive Cancer Network (NCCN) criteria for genetic testing. Participants are recruited through community oncology practices affiliated with the Michigan Oncology Quality Consortium (MOQC) and have used the Family Health History Tool (FHHT) to determine testing eligibility. The recruitment goal is 759 participants, who will be randomized to usual care or to either the virtual genetics navigator or the motivational interviewing intervention arms. The primary outcome will be the proportion of individuals who complete germline genetic testing within 6 months. DISCUSSION: This study addresses patient-level factors which are associated with the uptake of genetic testing. The study will test two different intervention approaches, both of which can help address the shortage of genetic counselors and improve access to care. TRIAL REGISTRATION: This study has been approved by the Institutional Review Board of the University of Michigan Medical School (HUM00192898) and registered in ClinicalTrials.gov (NCT05162846).

A retrospective cohort study of genetic referral and diagnosis of Lynch syndrome in patients with cutaneous sebaceous lesions.

Immunohistochemistry (IHC) of cutaneous sebaceous lesions (SL) can be used to screen patients for Lynch syndrome (LS). There is little data on rates of genetic referral and outcomes of genetic testing for patients with SL. This single-center retrospective study characterizes 400 + patients with SL, including IHC results, genetics referrals, and outcomes of genetic testing. Retrospective chart reviews were performed for patients with a pathology-confirmed diagnosis of SL at the University of Michigan between January 2009 and December 2019. 447 patients with 473 SL were identified. Excluding 20 patients with known LS, IHC was conducted in 173 (41%) patients. 92/173 (53%) patients had abnormal results. 69 of these 92 (75%) patients were referred to genetics. 32 additional patients were referred with normal IHC (n = 22) or without IHC (n = 10). Of 101 patients referred, 65 (64%) were seen and 47 (47%) completed genetic testing. 7/47 (15%) had pathogenic variants associated with LS, six with concordant abnormal IHC and one without IHC. Cancer genetics referral of patients with SL, particularly for lesions with abnormal IHC, yields a significant rate of LS diagnosis. Providers should consider genetics referral for patients with SL.

Motivational interviewing for genetic counseling: A unified framework for persuasive and equipoise conversations.

Genetic counselors (GCs) have traditionally been trained to adopt a position of equipoise or clinical neutrality. They provide information, answer questions, address barriers, and engage in shared decision-making, but generally, they do not prescribe a genetic test. Historically, GCs have generally been trained not to persuade the ambivalent or resistant patient. More recently, however, there has been discussion regarding when a greater degree of persuasion or directionality may be appropriate within genetic counseling (GC) and what role MI may play in this process. The role for "persuasive GC" is based on the premise that some genetic tests provide actionable information that would clearly benefit patients and families by impacting treatment or surveillance. For other tests, the benefits are less clear as they do not directly impact patient care or the benefits may be more subjective in nature, driven by patient values or psychological needs. For the former, we propose that GCs may adopt a more persuasive clinical approach while for the latter, a more traditional equipoise stance may be more appropriate. We suggest that motivational interviewing (MI) could serve as a unifying counseling model that allows GCs to handle both persuasive and equipoise encounters. For clearly beneficial tests, while directional, the MI encounter can still be non-directive, autonomy-supportive, and patient-centered. MI can also be adapted for equipoise situations, for example, placing less emphasis on eliciting and strengthening change talk as that is more a behavior change strategy than a shared decision-making strategy. The core principles and strategies of MI, such as autonomy support, evocation, open questions, reflective listening, and affirmation would apply to both persuasive and equipoise encounters. Key issues that merit discussion include how best to train GCs both during their initial and post-graduate education.

Integrating Medical Genetics Into Precision Oncology Practice in the Veterans Health Administration: The Time Is Now.

PURPOSE: Increased access and utilization of tumor profiling of cancers in our veteran population uncovered a modest number of potentially pathogenic germline variants (PPGVs) that require genetics referral for follow-up evaluation and germline sequencing. Challenges identified specific to the veteran population include paucity of genetics providers, either at a veteran's VA facility or nearby non-VA facilities. We sought to investigate the number of veterans who would benefit from having such resources at both local and national levels. METHODS: Annotated clinical reports of mutations identified by tumor-only profiling and medical records of veterans with solid tumors at the Veterans Administration Ann Arbor Healthcare System (VA AAHS) between 2015 and 2020 were reviewed. PPGVs were identified according to society recommendations (such as ESMO and American Board of Medical Genetics and Genomics), expert review, and/or previously published criteria. After the analysis of our local VA population, these same criteria were then applied to veterans in the National Precision Oncology Program (NPOP). RESULTS: Two hundred eight veterans underwent tumor profiling at the VA AAHS over the defined time period. This included 20 different primary tumor sites with over half (n = 130) being advanced cancer at diagnosis. Of these, 18 veterans (8.5%) had mutations suggestive of a PPGV. Applying these criteria to the larger NPOP database (n = 20,014), a similar percentage (6%) of PPGVs were identified. CONCLUSION: These results indicate a PPGV frequency (6%-9% of veterans) consistent with the prevalence of inherited cancer predisposition syndromes in the general population, underscoring the need for medical genetics as part of standard oncologic care for veterans. We explore current and future care delivery models to optimize incorporation of medical genetics and genetic counseling to best serve veterans needing such services.

Case Report of Cardiopulmonary Arrest During Pregnancy due to Opioid Overdose.

In the United States, the number of deaths related to overdose of heroin and other opioids, specifically among women of reproductive age, has been rising. This case report adds new knowledge to the limited scientific literature currently available. We describe the care of a 30-year-old pregnant (31.4 weeks gestation) woman who was found unresponsive from a suspected opioid overdose in a friend's home. In response to an unwitnessed cardiopulmonary arrest, the team initiated therapeutic hypothermia 12 hours after the event. Multiple interdisciplinary teams came together to care for this woman and fetus. Information sharing among care providers from multiple disciplines is needed to build expertise in managing the care of pregnant women who experience opioid overdose.

Systematic review of studies on measurement properties of instruments for adults published in the American Journal of Occupational Therapy, 2009-2013.

OBJECTIVE: We describe the methodological quality of recent studies on instrument development and testing published in the American Journal of Occupational Therapy (AJOT). METHOD: We conducted a systematic review using the COnsensus-based Standards for the selection of health status Measurement INstruments (COSMIN) checklist to appraise 48 articles on measurement properties of assessments for adults published in AJOT between 2009 and 2013. RESULTS: Most studies had adequate methodological quality in design and statistical analysis. Common methodological limitations included that methods used to examine internal consistency were not consistently linked to the theoretical constructs underpinning assessments; participants in some test-retest reliability studies were not stable during the interim period; and in several studies of reliability and convergent validity, sample sizes were inadequate. CONCLUSION: AJOT's dissemination of psychometric research evidence has made important contributions to moving the profession toward the American Occupational Therapy Association's Centennial Vision. This study's results provide a benchmark by which to evaluate future accomplishments.

Mast cell biology: introduction and overview.

In recent years, the field of mast cell biology has expanded well beyond the boundaries of atopic disorders and anaphy laxis, on which it has been historically focused. The biochemical and signaling events responsible for the development and regulation of mast cells has been increasingly studied, aided in large part by novel breakthroughs in laboratory techniques used to study these cells. The result of these studies has been a more comprehensive definition of mast cells that includes added insights to their overall biology as well as the various disease states that can now be traced to defects in mast cells. This introductory chapter outlines and highlights the various topics of mast cell biology that will be discussed in further detail in subsequent chapters.

Collagen distribution and expression of collagen-binding alpha1beta1 (VLA-1) and alpha2beta1 (VLA-2) integrins on CD4 and CD8 T cells during influenza infection.

Most viral infections occur in extralymphoid tissues, yet the mechanisms that regulate lymphocytes in these environments are poorly understood. One feature common to many extralymphoid environments is an abundance of extracellular matrix. We have studied the expression of two members of the beta(1) integrin family of collagen-binding receptors, alpha(1)beta(1) and alpha(2)beta(1) (CD49a, VLA-1 and CD49b, VLA-2, respectively), on CD4 and CD8 T cells during the response to influenza infection in the lung. Flow cytometry showed that whereas T cells infiltrating the lung and airways can express both CD49a and CD49b, CD49a expression was most strongly associated with the CD8+ subset. Conversely, though fewer CD4+ T cells expressed CD49a, most CD4+ cells in the lung tissue or airways expressed CD49b. This reciprocal pattern suggested that CD4 and CD8 T cells might localize differently within the lung tissue and this was supported by immunofluorescent analysis. CD8+ cells tended to localize in close proximity to the collagen IV-rich basement membranes of either the airways or blood vessels, whereas CD4+ cells tended to localize in the collagen I-rich interstitial spaces, with few in the airways. These observations suggest that CD4 T cell interaction with the tissue microenvironment is distinct from CD8 T cells and support the concept that CD4+ T cells in peripheral tissues are regulated differently than the CD8 subset.
