RESUMO
BACKGROUND: While 26% of US adults are disabled, only 3.1 to 9.3% of practicing physicians report having a disability. Ableism within medical training and practice diminishes physician diversity and wellbeing and contributes to healthcare disparities. OBJECTIVE: Explore physician barriers to disability equity and inclusion by examining internal medicine (IM) program directors' (PD) perspectives about recruiting and accommodating residents with disabilities (RWD). DESIGN: Qualitative study involving semi-structured virtual interviews (conducted December 2022-September 2023; analyzed through December 2023). PARTICIPANTS: PDs were recruited via email. Purposive sampling captured program diversity in size, location, and affiliations. Convenience sampling ensured PD diversity by gender, race/ethnicity, and age. APPROACH: Coders analyzed thematic and discursive content of interview transcripts to characterize PD perspectives about RWDs and accommodations. KEY RESULTS: Of the 15 programs represented, 4 had ≤ 49 and 8 had ≥ 100 total residents. Three were community-based; the rest had academic affiliations. On average, PDs had 17 (SD 8.2) years in practice. Most (11/15) identified as White race; 8/15 as female; and none as disabled. PDs characterized disability as a source of grit and empathy but also as an intrinsic deficit. They worried RWDs could have unpredictable absences and clinical incompetencies. Perceived accommodation challenges included inexperience, workload distribution, information asymmetry about accommodation needs or options, barriers to disclosure (e.g., discrimination concerns), and insufficient accommodation advertising. Perceived facilitators included advanced planning; clear, publicized processes; and access to expertise (e.g., occupational health, ombudsmen). CONCLUSIONS: PDs held contradictory views of RWDs. PD insights revealed opportunities to alleviate PD-RWD information asymmetry in recruitment/accommodation processes, which could help align needs and improve representation and inclusion.

The myriad microorganisms that live in close association with humans have diverse effects on physiology, yet the molecular bases for these impacts remain mostly unknown1-3. Classical pathogens often invade host tissues and modulate immune responses through interactions with human extracellular and secreted proteins (the 'exoproteome'). Commensal microorganisms may also facilitate niche colonization and shape host biology by engaging host exoproteins; however, direct exoproteome-microbiota interactions remain largely unexplored. Here we developed and validated a novel technology, BASEHIT, that enables proteome-scale assessment of human exoproteome-microbiome interactions. Using BASEHIT, we interrogated more than 1.7 million potential interactions between 519 human-associated bacterial strains from diverse phylogenies and tissues of origin and 3,324 human exoproteins. The resulting interactome revealed an extensive network of transkingdom connectivity consisting of thousands of previously undescribed host-microorganism interactions involving 383 strains and 651 host proteins. Specific binding patterns within this network implied underlying biological logic; for example, conspecific strains exhibited shared exoprotein-binding patterns, and individual tissue isolates uniquely bound tissue-specific exoproteins. Furthermore, we observed dozens of unique and often strain-specific interactions with potential roles in niche colonization, tissue remodelling and immunomodulation, and found that strains with differing host interaction profiles had divergent interactions with host cells in vitro and effects on the host immune system in vivo. Overall, these studies expose a previously unexplored landscape of molecular-level host-microbiota interactions that may underlie causal effects of indigenous microorganisms on human health and disease.

BACKGROUND & AIMS: Cystic fibrosis-related liver disease (CFLD) is a chronic cholangiopathy that increases morbidity and mortality in patients with CF. Current treatments are unsatisfactory, and incomplete understanding of CFLD pathogenesis hampers therapeutic development. We have previously shown that mouse CF cholangiocytes respond to lipopolysaccharide with excessive inflammation. Thus, we investigated the role of the gut-liver axis in the pathogenesis of CFLD. METHODS: Wild-type (WT), whole-body Cftr knockout (CFTR-KO) and gut-corrected (CFTR-KO-GC) mice were studied. Liver changes were assessed by immunohistochemistry and single-cell transcriptomics (single-cell RNA sequencing), inflammatory mediators were analysed by proteome array, faecal microbiota by 16S ribosomal RNA sequencing and gut permeability by FITC-dextran assay. RESULTS: The livers of CFTR-KO mice showed ductular proliferation and periportal inflammation, whereas livers of CFTR-KO-GC mice had no evident pathology. Single-cell RNA sequencing analysis of periportal cells showed increased presence of neutrophils, macrophages and T cells, and activation of pro-inflammatory and pathogen-mediated immune pathways in CFTR-KO livers, consistent with a response to gut-derived stimuli. CFTR-KO mice exhibited gut dysbiosis with enrichment of Enterobacteriaceae and Enterococcus spp., which was associated with increased intestinal permeability and mucosal inflammation, whereas gut dysbiosis and inflammation were absent in CFTR-KO-GC mice. Treatment with nonabsorbable antibiotics ameliorated intestinal permeability and liver inflammation in CFTR-KO mice. Faecal microbiota transfer from CFTR-KO to germ-free WT mice did not result in dysbiosis nor liver pathology, indicating that defective intestinal CFTR is required to maintain dysbiosis. CONCLUSION: Defective CFTR in the gut sustains a pathogenic microbiota, creates an inflammatory milieu, and alters intestinal permeability. These changes are necessary for the development of cholangiopathy. Restoring CFTR in the intestine or modulating the microbiota could be a promising strategy to prevent or attenuate liver disease. IMPACT AND IMPLICATIONS: Severe cystic fibrosis-related liver disease (CFLD) affects 10% of patients with cystic fibrosis (CF) and contributes to increased morbidity and mortality. Treatment options remain limited due to a lack of understanding of disease pathophysiology. The cystic fibrosis transmembrane conductance regulator (CFTR) mediates Cl- and HCO3- secretion in the biliary epithelium and its defective function is thought to cause cholestasis and excessive inflammatory responses in CF. However, our study in Cftr-knockout mice demonstrates that microbial dysbiosis, combined with increased intestinal permeability caused by defective CFTR in the intestinal mucosa, acts as a necessary co-factor for the development of CFLD-like liver pathology in mice. These findings uncover a major role for the gut microbiota in CFLD pathogenesis and call for further investigation and clinical validation to develop targeted therapeutic strategies acting on the gut-liver axis in CF.
RESUMO
Importance: Creating an inclusive and equitable learning environment is a national priority. Nevertheless, data reflecting medical students' perception of the climate of equity and inclusion are limited. Objective: To develop and validate an instrument to measure students' perceptions of the climate of equity and inclusion in medical school using data collected annually by the Association of American Medical Colleges (AAMC). Design, Setting, and Participants: The Promoting Diversity, Group Inclusion, and Equity tool was developed in 3 stages. A Delphi panel of 9 members identified survey items from preexisting AAMC data sources. Exploratory and confirmatory factor analysis was performed on student responses to AAMC surveys to construct the tool, which underwent rigorous psychometric validation. Participants were undergraduate medical students at Liaison Committee on Medical Education-accredited medical schools in the US who completed the 2015 to 2019 AAMC Year 2 Questionnaire (Y2Q), the administrations of 2016 to 2020 AAMC Graduation Questionnaire (GQ), or both. Data were analyzed from August 2020 to November 2023. Exposures: Student race and ethnicity, sex, sexual orientation, and socioeconomic status. Main Outcomes and Measures: Development and psychometric validation of the tool, including construct validity, internal consistency, and criterion validity. Results: Delphi panel members identified 146 survey items from the Y2Q and GQ reflecting students' perception of the climate of equity and inclusion, and responses to these survey items were obtained from 54â¯906 students for the Y2Q cohort (median [IQR] age, 24 [23-26] years; 29â¯208 [52.75%] were female, 11â¯389 [20.57%] were Asian, 4089 [7.39%] were multiracial, and 33â¯373 [60.28%] were White) and 61â¯998 for the GQ cohort (median [IQR] age, 27 [26-28] years; 30â¯793 [49.67%] were female, 13â¯049 [21.05%] were Asian, 4136 [6.67%] were multiracial, and 38â¯215 [61.64%] were White). Exploratory and confirmatory factor analyses of student responses identified 8 factors for the Y2Q model (faculty role modeling; student empowerment; student fellowship; cultural humility; faculty support for students; fostering a collaborative and safe environment; discrimination: race, ethnicity, and gender; and discrimination: sexual orientation) and 5 factors for the GQ model (faculty role modeling; student empowerment; faculty support for students; discrimination: race, ethnicity, and gender; and discrimination: sexual orientation). Confirmatory factor analysis indicated acceptable model fit (root mean square error of approximation of 0.05 [Y2Q] and 0.06 [GQ] and comparative fit indices of 0.95 [Y2Q] and 0.94 [GQ]). Cronbach α for individual factors demonstrated internal consistency ranging from 0.69 to 0.92 (Y2Q) and 0.76 to 0.95 (GQ). Conclusions and Relevance: This study found that the new tool is a reliable and psychometrically valid measure of medical students' perceptions of equity and inclusion in the learning environment.

Purpose The field of ophthalmology must become more reflective of the increasingly diverse U.S. population. This study characterizes students intending to pursue ophthalmology and practice in an underserved area versus other surgical and nonsurgical fields. Subjects Deidentified responses from 92,080 U.S. MD students who matriculated in the academic years beginning from 2007 to 2011 were obtained from the Association of American Medical Colleges (AAMC) Graduation Questionnaires. Methods Study participants were those who fully completed the AAMC Graduation Questionnaire. Chi-squared and multivariate logistical regressions were used for analyses. Results Ophthalmology intending graduates (OIG; n = 1,177) compared with other surgical intending graduates ( n = 7,955) were more likely to be female (adjusted odds ratio [aOR]: 1.46; 95% confidence interval [CI]: 1.28-1.66), Asian (1.71 [1.46-2.01]), and have conducted a research project with a faculty member (1.58 [1.26-1.98]). OIG compared with nonsurgery intending graduates ( n = 35,865) were more likely to have completed a research project with a faculty member (4.78 [3.86-5.92]), to be Asian (1.4 [1.21-1.62]), and have received scholarships (1.18 [1.04-1.34]). OIG were less likely to be female (0.64 [0.57-0.73]) and Black/African American (0.5 [0.33-0.74]). Among OIG, Black/African American students and multiracial students were more likely than non-Hispanic (NH) White students to report intention to practice in underserved areas (IPUA; 14.29 [1.82-111.88] and 2.5 [1.06-5.92]), respectively. OIG with global health experience were more likely to report IPUA (1.64 [1.2-2.25]). Conclusion Females and underrepresented in medicine (URM), respectively, were more likely to be nonsurgery intending graduates than OIG, which, if not addressed, may lead to a persistent underrepresentation of these groups in the field. In addition, URM students, including African American students, were more likely to report IPUA, which further emphasizes the importance of more URM students entering the field to address these growing gaps in medical care. Finally, we recommend increased mentorship to help address these disparities.
