RESUMEN
Framing the Issue: Medical education programs in the U.S. rely on the aphorism that faculty own the curriculum; that is, the specialized knowledge, skills, and attitudes of a physician are the province of the faculty to be delivered to tuition-paying students. From this view, the learner's role is one of passivity and deference. A contrasting approach, termed curriculum co-creation, frames education as a bi-lateral partnership. Co-creation results from learners, in collaboration with instructors, taking an active role in creating the goals and processes of an educational program. Such a partnership requires substantial revision of the expectations for both learners and instructors. In this Observations article, the idea of co-creation is applied to medical education and an aspirational vision for the role and value of faculty-student co-creation is advocated. Description and Explication: Co-creation partnerships of faculty and students occur in many forms, varying in degree of departure from traditional educational practice. Co-creation principles and partnerships can be deployed for almost all aspects of training including selection and organization of content, effective methods of instruction, and assessment of student learning. The outcomes of co-creation occur at three levels. The most specific outcome of co-creation is characterized by increased student engagement and enhanced learning. Broader outcomes include improved efficacy and value in the educational program and institution while, at the farthest-reaching level, a co-creative process can modify the medical profession itself. Although some specific instructional techniques to promote student involvement and input have historically been deployed in medical education, there is little evidence that students have ever been permitted to share in ownership. Implications for Medical Education: When fully embraced, curricular co-creation will be recognizable through improved student engagement and learning along with a revised understanding of how faculty-student relationships can foment reform in medical education and the culture of the profession. Further scholarship and research will be indispensable to examine how co-creative partnerships can flatten hierarchies within medical education and inspire the medical profession to be more inclusive and effective. Following the model of co-creation is expected to inspire learners by empowering them to participate fully as co-owners of their own education and prepare them to lead medical education in a different direction for the future.
RESUMEN
Regulated exocytosis is an essential process whereby specific cargo proteins are secreted in a stimulus-dependent manner. Cargo-containing secretory granules are synthesized in the trans-Golgi network (TGN); after budding from the TGN, granules undergo modifications, including an increase in size. These changes occur during a poorly understood process called secretory granule maturation. Here, we leverage the Drosophila larval salivary glands as a model to characterize a novel role for Rab GTPases during granule maturation. We find that secretory granules increase in size â¼300-fold between biogenesis and release, and loss of Rab1 or Rab11 reduces granule size. Surprisingly, we find that Rab1 and Rab11 localize to secretory granule membranes. Rab11 associates with granule membranes throughout maturation, and Rab11 recruits Rab1. In turn, Rab1 associates specifically with immature granules and drives granule growth. In addition to roles in granule growth, both Rab1 and Rab11 appear to have additional functions during exocytosis; Rab11 function is necessary for exocytosis, while the presence of Rab1 on immature granules may prevent precocious exocytosis. Overall, these results highlight a new role for Rab GTPases in secretory granule maturation.

INTRODUCTION: Frequent and severe bleeding events (SBE) in patients with inherited qualitative platelet disorders Bernard-Soulier Syndrome (BSS) and Glanzmann Thrombasthenia (GT) can lead to secondary iron deficiency anemia (IDA). SBE are primarily treated with platelet transfusions or recombinant activated factor VII (rFVIIa) infusions. The impact of IDA on bleeding management and disease outcomes is understudied. AIM: To evaluate bleeding management, outcomes, and any association with IDA in pediatric patients with BSS and GT. METHODS: Retrospective chart-review of pediatric patients with BSS or GT followed at a single hemophilia treatment center between 2007 and 2019. RESULTS: We identified 14 patients with BSS (n = 2) or GT (n = 12). Patients received rFVIIa (7%), platelet transfusions (7%), or a combination of both (57%) for SBE. Eleven patients (79%) had IDA requiring oral and/or intravenous iron replacement and 50% required red blood cell transfusions. Due to recurrent SBE and refractory IDA, three patients (21%) received rFVIIa prophylaxis at 90 µg/kilogram 2-3 times/week for ≥15 months. Patients initiated on rFVIIa prophylaxis had a median baseline hemoglobin of 9.8 g/dL (min-max: 8.0-10.7 g/dL) compared to 11.7 g/dL (8.4-13.8 g/dL) for patients treated on-demand. Following initiation of rFVIIa prophylaxis, median hemoglobin and ferritin increased by 1.3 g/dL (0.7-2.5 g/dL) and 14.6 ng/mL (0.2-42.9 ng/mL), respectively, and bleeding rates were reduced by 7-78%. CONCLUSION: IDA is a known complication of recurrent bleeding events in individuals with inherited bleeding disorders. Routine monitoring for IDA may help improve bleeding management and reduce bleed burden in BSS/GT.

Understanding the dynamics of "hot", highly energetic electrons resulting from nonradiative plasmon decay is crucial for optimizing applications in photocatalysis and energy conversion. This study presents an analysis of electron kinetics within plasmonic metals, focusing on the steady-state behavior during continuous-wave (CW) illumination. Using an inelastic spectroscopy technique, we quantify the temperature and lifetimes of distinct carrier populations during excitation. A significant finding is the monotonic increase in hot electron lifetime with decreases in electronic temperature. We also observe a 1.22× increase in hot electron temperature during intraband excitation compared to interband excitation and a corresponding 2.34× increase in carrier lifetime. The shorter lifetimes during interband excitation are hypothesized to result from direct recombination of nonthermal holes and hot electrons, highlighting steady-state kinetics. Our results help bridge the knowledge gap between ultrafast and steady-state spectroscopies, offering critical insights for optimizing plasmonic applications.
RESUMEN
Background: There is no consensus on what constitutes "early" pediatric palliative care (PPC) referral within pediatric oncology. Few studies report outcomes based on PPC timing. Objectives: Investigate associations between early (<12 weeks) or late (≥12 weeks from diagnosis) outpatient PPC consultation with demographics, advance care planning (ACP), and end-of-life (EOL) outcomes. Design: Retrospective chart and database review of demographic, disease, visit data, and PPC/EOL outcomes. Setting/Subjects: Deceased pediatric patients with cancer 0-27 years of age seen at an embedded consultative PPC clinic. Measurements: Patient demographics, disease characteristics, PPC/EOL outcomes: timing/receipt of ACP, hospice enrollment, do-not-resuscitate (DNR) documentation, hospital days in last 90 days of life, concordance between actual and preferred location of death, receipt of cardiopulmonary resuscitation (CPR) at EOL, and death in the intensive care unit. Results: Thirty-two patients received early and 118 received late PPC. Early outpatient PPC was associated with cancer type (p < 0.01). Early PPC (p = 0.04) and ACP documentation (p = 0.04) were associated with documentation of preferred location of death. Early PPC was associated with a preference for home death (p = 0.02). Timing of outpatient PPC was not associated with ACP documentation or other EOL outcomes. In the entire cohort, 73% of PPC patients received hospice, 74% had a DNR order, 87% did not receive CPR at EOL, and 90% died in their preferred location. Conclusions: When using a cutoff of 12 weeks from diagnosis, outpatient PPC timing was only associated with location of death metrics, likely due to high-quality PPC and EOL care among all patients.

Introduction: Opportunities to learn about education theory underpinning medical education are limited in both undergraduate and graduate medical education and predominantly focus on "student as teacher." Key components of education theory relevant to medical education, including learning theory, curricular design, and assessment design, are rarely included in student-as-teacher training. Opportunities for medical students to co-create curricula with faculty are scarce. Methods: We present the case study of a month-long, seminar-style course titled, Applications and Foundations of Education in Medical Education. We describe the course, report student feedback, and identify the value of curriculum co-creation expressed in student reflections. The course was designed by a faculty member with formal medical education training; students co-created their own learning outcomes through self-selected articles and personal reflections on the topics: How do people learn; what is the best way to teach; what is a curriculum; and how should students be assessed? Results: Forty-seven post-clinical students completed the course; 28 completed course evaluations. They strongly agreed that the class met its stated goals (4.89/5) and that faculty teaching (4.93/5) and supervision (4.93/5) were appropriate. Themes from student reflections expressed that the co-creation process was insightful about the profession itself, from the perspective of their own participation in learning how to become a member of the profession. Discussion: This course offered a unique opportunity for medical students to learn medical education beyond the skill of teaching. The course allowed deep immersion into current literature and offered the chance to plan and execute one's own learning.
RESUMEN
CONTEXT: Pediatric palliative care (PPC) improves quality of life and end-of-life outcomes for children with cancer, but often occurs late in the disease course. The Supportive Care Clinic (SCC) was launched in 2017 to expand outpatient PPC access. OBJECTIVES: To describe the inaugural four years (2017-2021) of an academic, consultative, embedded SCC within pediatric oncology. METHODS: Descriptive statistics (demographic, disease, treatment, visit, and end-of-life) and change over time were calculated. RESULTS: During the first four years, 248 patients (51.6% male; 58.1% White; 35.5% Black; 13.7% Hispanic/Latino) were seen in SCC, totaling 1,143 clinic visits (median 4, IQR 2,6), including 248 consultations and 895 follow-up visits. Clinic visits grew nearly 300% from year one to four. Primary diagnoses were central nervous system tumor (41.9%), solid tumor (37.5%), and leukemia/lymphoma (17.3%). The first point of PPC contact became SCC (70.6%) for most referred patients. Among the 136 deceased patients (54.8%), 77.9% had a do-not-resuscitate or Physician Orders for Life Sustaining Treatment in place, and 72.8% received hospice care. When known (n = 112), 89.3% died in their preferred location. The time from SCC consultation to death increased from 74 to 226 days over the four years (P < 0.0001). The proportion of SCC consultations that occurred greater than 90 days from death increased from 39.1% in year one to 85.0% in year four. CONCLUSION: Embedded SCC clinics can be successful, achieve steady growth, improve referrals and timing of PPC, and enhance end-of-life care for children with cancer. Large pediatric cancer centers should include SCC outpatient services.

OBJECTIVES: To investigate the landscape of cognitive impairment (CI) screening for adults with age-related hearing loss (ARHL) among otolaryngologists and audiologists. To identify provider factors and patient characteristics that impact rates of CI screening and referral. METHODS: A 15 question online survey was sent to members of the Georgia Society of Otolaryngology (GSO), Georgia Academy of Audiology (GAA), American Otological Society and American Neurotology Society (AOS/ANS), and posted on the web forum for two hearing disorders special interest groups within the American-Speech-Language-Hearing Association (ASHA). Responses were collected anonymously. Chi-square tests were used to compare responses. RESULTS: Of the 66 included respondents, 61% (n = 40) were otolaryngologists and 35% (n = 23) were audiologists. Respondents were significantly more likely to refer patients for CI assessment than to screen (64% vs 21%, respectively, P < .001). The complaint of a neurological symptom, such as memory loss, would prompt screening or referral for only 27.3% (n = 18) and 51.52% (n = 34) of respondents, respectively. Forty-two percent (n = 28) of respondents suggested CI screening with the MMSE vs 20% (n = 13) with the Montreal Cognitive Assessment. CONCLUSIONS: Despite recommendations for cognitive assessment in high-risk populations, such as older adults with ARHL, the practice of CI screening and referral is not yet commonplace among otolaryngologists and audiologists. These providers have a unique opportunity to assess adults with ARHL for CI and ensure appropriate referral. LEVEL OF EVIDENCE: 5.
RESUMEN
Interleukin-27 (IL-27) is an immunoregulatory cytokine that suppresses inflammation through multiple mechanisms, including induction of IL-10, but the transcriptional network mediating its diverse functions remains unclear. Combining temporal RNA profiling with computational algorithms, we predict 79 transcription factors induced by IL-27 in T cells. We validate 11 known and discover 5 positive (Cebpb, Fosl2, Tbx21, Hlx, and Atf3) and 2 negative (Irf9 and Irf8) Il10 regulators, generating an experimentally refined regulatory network for Il10. We report two central regulators, Prdm1 and Maf, that cooperatively drive the expression of signature genes induced by IL-27 in type 1 regulatory T cells, mediate IL-10 expression in all T helper cells, and determine the regulatory phenotype of colonic Foxp3+ regulatory T cells. Prdm1/Maf double-knockout mice develop spontaneous colitis, phenocopying ll10-deficient mice. Our work provides insights into IL-27-driven transcriptional networks and identifies two shared Il10 regulators that orchestrate immunoregulatory programs across T helper cell subsets.
