Case-Based Specialty Training for Medical Students to Elicit Social Determinants of Health.

Introduction: Without explicit education and training on how social determinants of health (SDoH) impact patient care and health outcomes, medical schools are failing to effectively equip future physicians to serve their patients. We created this workshop on health equity with a focus on SDoH to help students more effectively communicate with diverse populations. Methods: Third-year medical students and faculty were provided with class guides, learning objectives, role-play vignettes containing clerkship-specific history and physical exams, schedules, and discussion questions during a 2-hour session centered on SDoH. The workshop's impact was measured through mixed-methods analysis of surveys. Results: Based on pre- and postsurvey results from 87 participants, medical students strongly agreed that (1) SDoH factor more into a patient's health outcomes than the clinical encounter (pre: 67%, post: 87%), (2) it is their duty to gather information about SDoH (pre: 86%, post: 97%), (3) neighborhood safety is one of the key SDoH (pre: 88%, post: 97%), (4) they understood the impact of upstream interventions (pre: 35%, post: 93%), (5) they could efficiently screen all patients for SDoH at every medical encounter (pre: 27%, post: 86%), and (6) they could find preliminary resources to quickly assist patients in need of help regarding particular SDoH (pre: 26%, post: 85%). Discussion: This was the first iteration of this workshop; challenges involved piloting the content, time restraints, and organizational structure of the workshop design. Future directions include making SDoH curricula an integral part of undergraduate medical education and diverse clinical environments.

Risk of Severe Acute Respiratory Syndrome Coronavirus 2 Infection Following Prior Infection or Vaccination.

BACKGROUND: The extent to which infection versus vaccination has conferred similarly durable severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) immunity during the Omicron era remains unclear. METHODS: In a cohort of 4496 adults under continued serological surveillance throughout the first year of Omicron-predominant SARS-CoV-2 transmission, we examined incidence of new infection among individuals whose last known antigenic exposure was either recent (<90 days) or remote (≥90 days) infection or vaccination. RESULTS: We adjudicated 2053 new-onset infections occurring between 15 December 2021 through 22 December 2022. In multivariable-adjusted analyses, compared to individuals whose last known exposure was remote vaccination, those with recent vaccination (odds ratio [OR], 0.82 [95% confidence interval {CI}, .73-.93]; P = .002) or recent infection (OR, 0.14 [95% CI, .05-.45]; P = .001) had lower risk for new infection within the subsequent 90-day period. Given a significant age interaction (P = .004), we found that remote infection compared to remote vaccination was associated with significantly greater new infection risk in persons aged ≥60 years (OR, 1.88 [95% CI, 1.13-3.14]; P = .015) with no difference seen in those <60 years (1.03 [95% CI, .69-1.53]; P = .88). CONCLUSIONS: During the initial year of Omicron, prior infection and vaccination both offered protection against new infection. However, remote prior infection was less protective than remote vaccination for individuals aged ≥60 years. In older adults, immunity gained from vaccination appeared more durable than immunity gained from infection.

Melanoma: Does It Present Differently in Darker Skin Tones?

Introduction: There are vast differences in clinical presentations of melanoma across skin tones. Individuals with darker skin tones tend to have a higher prevalence of advanced-stage melanoma, which correlates with increased mortality. We designed this interactive workshop to increase nursing and medical trainees' awareness of the epidemiology, prevention, and treatment of melanoma in individuals of darker skin tones. Methods: The Kern model was used in the design, implementation, and evaluation of the workshop. The 75-minute workshop consisted of a PowerPoint presentation, video-based reflection activities, and case studies. Evaluation consisted of pre- and postworkshop questionnaires. The workshop was implemented two times among 63 nursing students, 11 medical students/residents, and six medical faculty. Results: Seventy-one participants completed the pre- and postworkshop evaluations. A comparison of pre- and postworkshop responses utilizing the Wilcoxon matched-pair signed rank test showed a statistically significant increase in learners' confidence to address each learning objective. Discussion: Through this interactive educational presentation, medical and nursing trainees can gain heightened awareness of melanoma across various skin tones, especially unique presentations in darker skin tones.

Targeting PELP1 oncogenic signaling in TNBC with the small molecule inhibitor SMIP34.

PURPOSE: Triple-negative breast cancer (TNBC) is the most aggressive subtype of breast cancer. Oncogenic PELP1 is frequently overexpressed in TNBC, and it has been demonstrated that PELP1 signaling is essential for TNBC progression. The therapeutic utility of targeting PELP1 in TNBC, however, remains unknown. In this study, we investigated the effectiveness of SMIP34, a recently developed PELP1 inhibitor for the treatment of TNBC. METHODS: To ascertain the impact of SMIP34 treatment, we used seven different TNBC models for testing cell viability, colony formation, invasion, apoptosis, and cell cycle analysis. Western blotting and RT-qPCR were used to determine the mechanistic insights of SMIP34 action. Using xenograft and PDX tumors, the ability of SMIP34 in suppressing proliferation was examined both ex vivo and in vivo. RESULTS: TNBC cells' viability, colony formation, and invasiveness were all decreased by SMIP34 in in vitro cell-based assays, while apoptosis was increased. SMIP34 treatment promoted the degradation of PELP1 through the proteasome pathway. RT-qPCR analyses confirmed that SMIP34 treatment downregulated PELP1 target genes. Further, SMIP34 treatment substantially downregulated PELP1 mediated extranuclear signaling including ERK, mTOR, S6 and 4EBP1. Mechanistic studies confirmed downregulation of PELP1 mediated ribosomal biogenesis functions including downregulation of cMyc and Rix complex proteins LAS1L, TEX-10, and SENP3. The proliferation of TNBC tumor tissues was decreased in explant experiments by SMIP34. Additionally, SMIP34 treatment markedly decreased tumor progression in both TNBC xenograft and PDX models. CONCLUSIONS: Together, these findings from in vitro, ex vivo, and in vivo models show that SMIP34 may be a useful therapeutic agent for inhibiting PELP1 signaling in TNBC.

Office of Diversity, Equity, and Inclusion: Engagement and Leadership Opportunities for Trainees.

Introduction: To achieve a healthier future for all, improving diversity through efforts such as diversifying faculty and leadership in academic medicine is imperative. Therefore, medical trainees (medical students, residents, fellows) from groups underrepresented in medicine (UiM) are encouraged to pursue academic careers and have opportunities to gain faculty leadership skills during their training. Trainees also need exposure to the leadership positions within various offices of an academic institution such as the Office of Diversity, Equity, and Inclusion (DEI). The goal of this module is to expose UiM trainees to the Office of DEI and leadership competencies that can be obtained via service and leadership opportunities with it. Methods: The Kern model was used in the development, implementation, and evaluation of this 75-minute workshop. The workshop consisted of a PowerPoint presentation, reflection exercises, and case discussion to raise trainees' awareness of the Office of DEI and opportunities to become engaged with and develop faculty leadership competencies through the office. Results: Sixty-six diverse learners across three sites completed pre- and postworkshop surveys. Ninety-five percent of participants agreed or strongly agreed that the learning objectives of the workshop had been met. Discussion: Overall, this interactive workshop facilitated learners' awareness of the responsibilities of the Office of DEI and opportunities for learners to develop faculty leadership competencies through engagement. Although primarily evaluated among medical students, the module can be of use to learners and faculty of other health professions programs with an Office of DEI.

Primary adrenal insufficiency masking as an adrenal B-cell lymphoma.

We report here a woman in her 70s presenting with adrenal insufficiency secondary to a primary adrenal lymphoma. The patient had a previous history of aphthous ulcers on dexamethasone and was referred to endocrinology with symptoms of fatigue and orthostasis. Subsequent Cosyntropin stimulation showed primary adrenal insufficiency and adrenal CT demonstrated large infiltrative masses. Adrenal biopsy confirmed the diagnosis of primary adrenal lymphoma of the B-cell type. This case demonstrates the importance of including lymphoma in the differential diagnosis of adrenal insufficiency, particularly in the elderly population and in the setting of negative 21-hydroxlyase antibody results.

A First-in-Class Inhibitor of ER Coregulator PELP1 Targets ER+ Breast Cancer.

Most patients with estrogen receptor alpha-positive (ER+) breast cancers initially respond to treatment but eventually develop therapy resistance with disease progression. Overexpression of oncogenic ER coregulators, including proline, glutamic acid, and leucine-rich protein 1 (PELP1), are implicated in breast cancer progression. The lack of small molecules that inhibits PELP1 represents a major knowledge gap. Here, using a yeast-two-hybrid screen, we identified novel peptide inhibitors of PELP1 (PIP). Biochemical assays demonstrated that one of these peptides, PIP1, directly interacted with PELP1 to block PELP1 oncogenic functions. Computational modeling of PIP1 revealed key residues contributing to its activity and facilitated the development of a small-molecule inhibitor of PELP1, SMIP34, and further analyses confirmed that SMIP34 directly bound to PELP1. In breast cancer cells, SMIP34 reduced cell growth in a dose-dependent manner. SMIP34 inhibited proliferation of not only wild-type (WT) but also mutant (MT) ER+ and therapy-resistant breast cancer cells, in part by inducing PELP1 degradation via the proteasome pathway. RNA sequencing analyses showed that SMIP34 treatment altered the expression of genes associated with estrogen response, cell cycle, and apoptosis pathways. In cell line-derived and patient-derived xenografts of both WT and MT ER+ breast cancer models, SMIP34 reduced proliferation and significantly suppressed tumor progression. Collectively, these results demonstrate SMIP34 as a first-in-class inhibitor of oncogenic PELP1 signaling in advanced breast cancer. SIGNIFICANCE: Development of a novel inhibitor of oncogenic PELP1 provides potential therapeutic avenues for treating therapy-resistant, advanced ER+ breast cancer.

Mistreatment in Residency: Intervening With the REWIND Communication Tool.

Introduction: There is a lack of curricula addressing the alarming rates of resident physician mistreatment. As the ACGME works to address diversity, equity, and inclusion in GME, there has been increasing attention paid to the issue of mistreatment. Previous studies have noted a high prevalence of mistreatment within GME. Despite this, there are few published interventions to address the mistreatment of residents. We developed a workshop for residents to provide an overview of mistreatment in residency and teach them REWIND (relax, express, why, inquire, negotiate, determine), a communication tool to address mistreatment directly. Methods: We designed a 60-minute workshop for residents with didactics on mistreatment in GME, followed by three case discussions. Four case scenarios were developed to represent different types of mistreatment and situations. We implemented the workshop twice and asked participants to self-rate proficiency around the workshop objectives with pre- and postsurveys. Results: A total of 11 GME learners completed both the pre- and postsurveys between the two workshop implementations. GME learners who responded demonstrated significantly higher self-rated proficiency on each objective postworkshop compared to preworkshop (p < .05). Free responses on the survey demonstrated that participants particularly enjoyed the case discussions and wanted more practice with REWIND. Discussion: Our workshop improved participant self-rated proficiency around the mistreatment of resident physicians. The workshop can be used in the future as part of a multifaceted institutional response to mistreatment.

COVID-19 Education for Health Professionals Caring for Spanish-Speaking Patients.

Introduction: The COVID-19 pandemic has disproportionately affected Hispanics in the United States, who make up 18% of US inhabitants but 29% of COVID-19 cases as of June 2021. Recent studies have attributed higher COVID-19 infection, hospitalization, and death rates among Hispanics to social determinants of health. Given that the majority of US Hispanics are bilingual or Spanish-dominant, it is imperative for health care providers to be prepared to discuss COVID-19 prevention and treatment in Spanish. Methods: We developed an interactive workshop aimed at increasing health professionals' confidence in discussing COVID-19 prevention, risk factors, and treatments with Spanish-speaking patients. Learners were expected to have an intermediate level or higher proficiency in medical Spanish. The workshop consisted of a PowerPoint presentation and English/Spanish scripts to facilitate interactive learning. The workshop was evaluated using a postworkshop questionnaire to assess learners' perceived confidence in communicating with Spanish-speaking patients. Results: The workshop was implemented with 70 participants, who had diverse ethnoracial identities and professional roles, at five different medical schools. Fifty-three participants completed the postworkshop questionnaire. More than 50% reported near complete to complete confidence in meeting the three learning objectives. Discussion: With Hispanics being the largest non-White ethnoracial group in the US and being disproportionally affected by COVID-19, it is essential for health professionals to access training tools that allow them to practice medical Spanish. This module can uniquely aid in the preparation of health professionals caring for Spanish-speaking patients who present with COVID-19 symptoms.

LGBTQ+ Worker Protections: Implications for Academic Medicine Today and in the Future.

The Supreme Court's 2020 ruling prohibiting workplace discrimination based on sexual orientation or gender identity ( Bostock v Clayton County ) offers new legal protections for LGBTQ+ employees and allies and new opportunities for academic medicine to advance LGBTQ+ inclusion at their institutions. In this perspective piece, the authors examine the history of LGBTQ+ community recognition, tolerance, protections, and ongoing inclusion and the advocacy efforts led by LGBTQ+ patients, community activists, and medical colleagues. They also examine the current limitations of the court's ruling and recommend future actions to advance workplace and health equity. While recent advancements in equality have not erased chronic barriers to inclusion and advancement, they can pave the way for leaders in research, education, and clinical care to shape national health guidelines and policies that impact the health of all Americans.

The CSF1R-Microglia Axis Has Protective Host-Specific Roles During Neurotropic Picornavirus Infection.

Viral encephalitis is a major cause of morbidity and mortality, but the manifestation of disease varies greatly between individuals even in response to the same virus. Microglia are professional antigen presenting cells that reside in the central nervous system (CNS) parenchyma that are poised to respond to viral insults. However, the role of microglia in initiating and coordinating the antiviral response is not completely understood. Utilizing Theiler's murine encephalomyelitis virus (TMEV), a neurotropic picornavirus, and PLX5622, a small molecule inhibitor of colony-stimulating factor 1 receptor (CSF1R) signaling that can deplete microglia in the CNS; we investigated the role of the CSF1R-microglia axis in neurotropic picornavirus infection of C57BL/6J and SJL/J mice. These mouse strains differ in their ability to clear TMEV and exhibit different neurological disease in response to TMEV infection. CSF1R antagonism in C57BL/6J mice, which normally clear TMEV in the CNS, led to acute fatal encephalitis. In contrast, CSF1R antagonism in SJL/J mice, which normally develop a chronic CNS TMEV infection, did not result in acute encephalitis, but exacerbated TMEV-induced demyelination. Immunologically, inhibition of CSF1R in C57BL/6J mice reduced major histocompatibility complex II expression in microglia, decreased the proportion of regulatory T cells in the CNS, and upregulated proinflammatory pathways in CNS T cells. Acute CSF1R inhibition in SJL/J mice had no effect on microglial MHC-II expression and upregulated anti-inflammatory pathways in CNS T cells, however chronic CSF1R inhibition resulted in broad immunosuppression. Our results demonstrate strain-specific effects of the CSF1R-microglia axis in the context of neurotropic viral infection as well as inherent differences in microglial antigen presentation and subsequent T cell crosstalk that contribute to susceptibility to neurotropic picornavirus infection.

Tuning the Dimensionality of Excitons in Colloidal Quantum Dot Molecules.

Electrically coupled quantum dots (QDs) can support unique optoelectronic properties arising from the superposition of single-particle excited states. Experimental methods for integrating colloidal QDs within the same nano-object, however, have remained elusive to the rational design. Here, we demonstrate a chemical strategy that allows for the assembling of colloidal QDs into coupled composites, where proximal interactions give rise to unique optoelectronic behavior. The assembly method employing "adhesive" surfactants was used to fabricate both homogeneous (e.g., CdS-CdS, PbS-PbS, CdSe-CdSe) and heterogeneous (e.g., PbS-CdS, CdS-CdSe) nanoparticle assemblies, exhibiting quasi-one-dimensional exciton fine structure. In addition, tunable mixing of single-particle exciton states was achieved for dimer-like assemblies of CdSe/CdS core-shell nanocrystals. The nanoparticle assembly mechanism was explained within the viscoelastic interaction theory adapted for molten-surface colloids. We expect that the present work will provide the synthetic and theoretical foundation needed for building assemblies of many inorganic nanocrystals.

Computational and Experimental Analysis of Gold Nanorods in Terms of Their Morphology: Spectral Absorption and Local Field Enhancement.

A nanoparticle's shape and size determine its optical properties. Nanorods are nanoparticles that have double absorption bands associated to surface plasmon oscillations along their two main axes. In this work, we analize the optical response of gold nanorods with numerical simulations and spectral absorption measurements to evaluate their local field enhancement-which is key for surface-enhanced Raman spectroscopic (SERS) applications. Our experimental results are in good agreement with finite element method (FEM) simulations for the spectral optical absorption of the nanoparticles. We also observed a strong dependence of the optical properties of gold nanorods on their geometrical dimension and shape. Our numerical simulations helped us reveal the importance of the nanorods' morphology generated during the synthesis stage in the evaluation of absorption and local field enhancement. The application of these gold nanorods in surface-enhancement Raman spectroscopy is analyzed numerically, and results in a 5.8×104 amplification factor when comparing the values obtained for the nanorod deposited on a dielectric substrate compared to the nanorod immersed in water.

HIV Pre-exposure Prophylaxis Education for Clinicians Caring for Spanish-Speaking Men Who Have Sex With Men (MSM).

Introduction: A growing number of Liaison Committee on Medical Education-accredited allopathic medical schools offer formal bilingual (English and Spanish) medical education, and numerous other schools offer medical Spanish through elective workshops as part of their curricula. One significant health disparity in the Hispanic community is the incidence of HIV among Spanish-speaking men who have sex with men (MSM). Pre-exposure prophylaxis (PrEP) has emerged as an effective strategy to reduce the risk of HIV transmission. Methods: We developed an education module to train clinicians to discuss PrEP with Spanish-speaking MSM. Our module is adapted from an English module on PrEP education. It includes a Spanish-language PowerPoint slide deck with information about PrEP as well as a Spanish-language videotaped scripted clinical encounter. Results: The module was implemented on three occasions with 18 participants, and learners reported increased comfort in discussing and confidence in prescribing PrEP with Spanish-speaking patients. Discussion: This workshop can be incorporated within medical Spanish curriculums offered at health professional schools and community-based organizations dedicated to reducing the HIV burden in the Spanish-speaking Hispanic community.

Office of Medical Education: Opportunities for Trainees to Engage and Lead in Curricular Innovation and Reform.

Introduction: The AAMC prioritizes promoting a diverse and culturally competent workforce which is thought to have a positive impact on the health of people living in the US. There is a lack of diversity in the current landscape of academic medicine and strategies are needed to effect change. This module introduced undergraduate and graduate medical trainees to leadership skills and opportunities in curriculum innovation and reform by learning about and interacting with the office of medical education (OME) at their institutions. Methods: We implemented a workshop using small-group case discussions and didactics to help medical students and residents learn how to: (1) describe the structure and functions of an OME, (2) describe leadership competencies associated with various roles within the OME, and (3) identify opportunities for trainees to engage with the OME on curricular innovation and reform, especially advancing diversity and inclusion. Results: Across three sites, 45 learners completed partial or full workshop evaluations. Of learners, 22 (49%) were not knowledgeable and 13 (29%) were somewhat knowledgeable in identifying leadership opportunities for trainees to become engaged through the OME. There was a statistically significant increase in confidence after the workshop in "discussing an interdisciplinary approach to the creation of a medical education innovation," and, "assessing the need for curricula change." Over 90% of attendees agreed learning objectives were met. Discussion: This workshop succeeded in promoting awareness of the structure and function of OMEs and confidence in seeking opportunities to become engaged in medical education, especially in advancing diversity and inclusion.
