From intention to action: Assessing need and creating a JEDI toolkit for individuals teaching cancer genetics curriculum.

The effects of systemic racism persist in cancer care and contribute to disparities. Recent publications have shown that injustices and biases continue to affect the field of genetic counseling in the form of microaggressions, barriers to entry, and disparate patient care. Toolkits are one method that can be used to incorporate anti-racist practices to address this need. We sought to identify the current state of coverage of Justice, Equity, Diversity, and Inclusion (JEDI) topics during cancer genetics training across genetic counseling training programs (GCTPs) and utilize this information to create a novel toolkit that would support integration of anti-racist pedagogy into formal genetic counseling curricula. To accomplish this aim, recent learners and program directors/cancer course instructors were surveyed using two novel surveys. The survey responses, which helped to identify the frequency and manner of incorporation of JEDI topics into cancer curricula in GCTPs, led to the development of an educational toolkit. Recent learners and instructors/program directors identified multiple content areas within cancer genetic training in which they felt incorporating JEDI topics would be desired. A toolkit to support the incorporation of anti-racist teaching and practices into cancer genetics training in GCTPs was created. This toolkit can be adapted to focus on topics relevant to the care of other marginalized identities and to support the learning of other healthcare providers receiving cancer genetics education.

Genetic counselors' response types to prenatal patient deferring or attributing religious/spiritual statements: An exploratory study of US genetic counselors.

Research shows religiosity and spirituality (R/S) influence genetic counseling patients' and families' risk perception, decision-making, and coping. No published studies have examined how genetic counselors respond to patient-initiated R/S statements. This exploratory study examined genetic counselors' response types and reasons for their responses to two prenatal patient's R/S statements. Genetic counselors (n = 225) recruited through a National Society of Genetic Counselors eblast completed a survey containing two hypothetical scenarios regarding a prenatal patient's receipt of a trisomy 18 diagnosis. Scenarios were identical except for the last patient statement: "God makes everything possible…we leave things in his hands" (a deferring statement) or "I feel like God is punishing me for something I did" (an attributing statement). Imagining they were the counselor, participants wrote a response to each scenario and provided reasons for their response. Responses were analyzed using the Helping Skills Verbal Response System. MANOVA and chi-square tests, examining differences in response type based on patient statement (deferring or attributing), participant comfort with R/S, and years of experience, yielded a significant multivariate effect for scenario (p < 0.001). Responses to the deferring statement scenario contained a greater proportion of content statements (p < 0.001), closed questions (p < 0.001), and information-giving (p < 0.001). Responses to the attributing statement scenario contained a greater proportion of open questions (p = 0.05), influencing statements (p < 0.001), and affective statements (p = 0.006). Neither comfort with R/S nor genetic counseling experience significantly affected response type. Thematic analysis of reasons for responses yielded nine themes. Most prevalent were exploration (of the patient's statement), validation, correction (of patient's beliefs), and reassurance. The findings reflect stylistic differences in how and why genetic counselors respond to patients.

Fgf10-Hippo Epithelial-Mesenchymal Crosstalk Maintains and Recruits Lung Basal Stem Cells.

The lung harbors its basal stem/progenitor cells (BSCs) in the protected environment of the cartilaginous airways. After major lung injuries, BSCs are activated and recruited to sites of injury. Here, we show that during homeostasis, BSCs in cartilaginous airways maintain their stem cell state by downregulating the Hippo pathway (resulting in increased nuclear Yap), which generates a localized Fgf10-expressing stromal niche; in contrast, differentiated epithelial cells in non-cartilaginous airways maintain quiescence by activating the Hippo pathway and inhibiting Fgf10 expression in airway smooth muscle cells (ASMCs). However, upon injury, surviving differentiated epithelial cells spread to maintain barrier function and recruit integrin-linked kinase to adhesion sites, which leads to Merlin degradation, downregulation of the Hippo pathway, nuclear Yap translocation, and expression and secretion of Wnt7b. Epithelial-derived Wnt7b, then in turn, induces Fgf10 expression in ASMCs, which extends the BSC niche to promote regeneration.

Plasma cell-free mitochondrial DNA declines in response to prolonged moderate aerobic exercise.

Increased plasma cell-free mitochondrial DNA (cf-mDNA), a damage-associated molecular pattern (DAMP) produced by cellular injury, contributes to neutrophil activation/inflammation in trauma patients and arises in cancer and autoimmunity. To further understand relationships between cf-mDNA released by tissue injury, inflammation, and health benefits of exercise, we examined cf-mDNA response to prolonged moderate aerobic exercise. Seven healthy moderately trained young men (age = 22.4 ± 1.2) completed a treadmill exercise trial for 90 min at 60% VO2 max and a resting control trial. Blood was sampled immediately prior to exercise (0 min = baseline), during (+18, +54 min), immediately after (+90 min), and after recovery (R40). Plasma was analyzed for cf-mDNA, IL-6, and lactate. A significant difference in cf-mDNA response was observed between exercise and control trials, with cf-mDNA levels reduced during exercise at +54 and +90 (with or without plasma volume shift correction). Declines in cf-mDNA were accompanied by increased lactate and followed by an increase in IL-6, suggesting a temporal association with muscle stress and inflammatory processes. Our novel finding of cf-mDNA decline with prolonged moderate treadmill exercise provides evidence for increased clearance from or reduced release of cf-mDNA into the blood with prolonged exercise. These studies contrast with previous investigations involving exhaustive short-term treadmill exercise, in which no change in cf-mDNA levels were reported, and contribute to our understanding of differences between exercise- and trauma-induced inflammation. We propose that transient declines in cf-mDNA may induce health benefits, by reducing systemic inflammation.
