ABSTRACT

Inpatient educational conferences are a key part of internal medicine residency training. Many residencies made conferences virtual during the COVID-19 pandemic, and are now returning to in-person sessions. As we navigate this change, we can seize this opportunity to re-evaluate the role that inpatient conferences serve in resident education. In this paper, we briefly review the history of inpatient educational conferences before offering five recommendations for improvement. Our recommendations include grounding conference formats in educational theory, leveraging the expertise of all potential educators, broadening content to include health equity and justice throughout all curricula, and explicitly focusing on cultivating community among participants. Recognizing that each residency program is different, we anticipate that these recommendations may be implemented differently based on program size, available resources, and current institutional practices. We also include examples of prior successful curricular reforms aligned with our principles. We hope these recommendations ensure inpatient conferences continue to be a central part of residency education for future generations of internal medicine residents.

ABSTRACT

BACKGROUND: Pregnant patients with Marfan's syndrome (MFS) are at an increased risk for adverse aortic outcomes. While beta-blockers are used to slow aortic root dilatation in nonpregnant MFS patients, the benefit of such therapy in pregnant MFS patients remains controversial. The purpose of this study was to investigate the effect of beta-blockers on aortic root dilatation during pregnancy in MFS patients. METHODS: This was a longitudinal single-center retrospective cohort study of females with MFS who completed a pregnancy between 2004 and 2020. Clinical, fetal, and echocardiographic data were compared in patients on- versus off-beta-blockers during pregnancy. RESULTS: A total of 20 pregnancies completed by 19 patients were evaluated. Beta-blocker therapy was initiated or continued in 13 (65%) of the 20 pregnancies. Pregnancies on-beta-blocker therapy experienced less aortic growth compared with those off-beta-blockers (0.10 [interquartile range, IQR: 0.10-0.20] vs. 0.30 cm [IQR: 0.25-0.35]; p = 0.03). Using univariate linear regression, maximum systolic blood pressures (SBP), increase in SBP, and absence of beta-blocker use in pregnancy were found to be significantly associated with greater increase in aortic diameter during pregnancy. There were no differences in rates of fetal growth restriction between pregnancies on- versus off-beta-blockers. CONCLUSION: This is the first study that we are aware of to evaluate changes in aortic dimensions in MFS pregnancies stratified by beta-blocker use. Beta-blocker therapy was found to be associated with less aortic root growth during pregnancy in MFS patients.

ABSTRACT

The pulse oximeter is a ubiquitous clinical tool used to estimate blood oxygen concentrations. However, decreased accuracy of pulse oximetry in patients with dark skin tones has been demonstrated since as early as 1985. Most commonly, pulse oximeters may overestimate the true oxygen saturation in individuals with dark skin tones, leading to higher rates of occult hypoxemia (i.e., clinically unrecognized low blood oxygen saturation). Overestimation of oxygen saturation in patients with dark skin tones has serious clinical implications, as these patients may receive insufficiently rigorous medical care when pulse oximeter measurements suggest that their oxygen saturation is higher than the true value. Recent studies have linked pulse oximeter inaccuracy to worse clinical outcomes, suggesting that pulse oximeter inaccuracy contributes to known racial health disparities. The magnitude of device inaccuracy varies by pulse oximeter manufacturer, sensor type, and arterial oxygen saturation. The underlying reasons for decreased pulse oximeter accuracy for individuals with dark skin tones may be related to failure to control for increased absorption of red light by melanin during device development and insufficient inclusion of individuals with dark skin tones during device calibration. Inadequate regulatory standards for device approval may also play a role in decreased accuracy. Awareness of potential pulse oximeter limitations is an important step for providers and may encourage the consideration of additional clinical information for management decisions. Ultimately, stricter regulatory requirements for oximeter approval and increased manufacturer transparency regarding device performance are required to mitigate this racial bias.

ABSTRACT

Little progress has been made in improving racial, gender, or intersectional diversity within academic internal medicine (IM). Chief Residency fulfills a unique opportunity to target diversity efforts; Chief Residents (CR) are integral in creating an inclusive environment and support system for IM trainees, and the position serves as a steppingstone for future leadership positions within academia. However, the CR selection process often lacks transparency and includes steps that are fraught with bias, thereby disadvantaging underrepresented minority groups from gaining important experience needed to climb the academic ladder. We describe a more standardized selection process that will improve recruitment and selection of more diverse CRs and ultimately improve the recruitment, retention, and promotion of more diverse faculty within academic internal medicine. Key recommendations include an open call for applications, the use of standardized and structured interviews, and the formation of a diverse selection committee to conduct a transparent selection process based on explicitly defined criteria.

ABSTRACT

Health disparities fall along racial lines, in part, due to structural inequalities limiting health care access. The concept of race is often taught in health professions education with a clear biologic underpinning despite the significant debate in the literature as to whether race is a social or biologic construct. The teaching of race as a biologic construct, however, allows for the simplification of race as a risk factor for disease. As health care providers, it is part of our professional responsibility and duty to patients to think and talk about race in a way that is cognizant of broader historical, political, and cultural literature and context. Openly discussing the topic of race in medicine is not only uncomfortable but also difficult given its controversies and complicated context. In response, we provide several evidence-based steps to guide discussions around race in clinical settings, while also hopefully limiting the use of bias and racism in the practice of medicine.

ABSTRACT

Exosomes are 30-150 nm vesicles secreted by a wide range of mammalian cells that can contain microRNA (miRNA). To test if marrow stromal cell (MSC) exosomes could be used as a vehicle for delivery of anti-tumor miRNAs, we transfected MSCs with a miR-146b expression plasmid, and harvested exosomes released by the MSCs. Intra-tumor injection of exosomes derived from miR-146-expressing MSCs significantly reduced glioma xenograft growth in a rat model of primary brain tumor.
