The Propagation of Race and Racial Differences as Biological in Preclinical Education.

Modern scientific research has demonstrated that race is a social construct rather than a biological construct. Yet, medical education research suggests that medical faculty still sometimes characterize race and racial differences as biological during lectures. To explore this dynamic, we reviewed (1) how race is presented in the preclinical curriculum of an undergraduate medical institution and (2) how preclinical faculty both define race and attribute disparate health outcomes to race. In part 1 of the study, the authors conducted a retrospective summative content analysis of all first-year preclinical lectures during the 2018-2019 academic year. In part 2, the authors administered a survey to preclinical faculty on the understanding of race, and responses were assessed through conventional content analysis. A number of faculty suggested a biological basis for racial differences during lectures, though survey results suggested that the majority characterize race as a social construct. Faculty knowledge of race and racial differences as a social construct was not reflected in the majority of the curricular analysis. Instead, the lectures showed that faculty predominantly discussed race without context (e.g., as a standalone epidemiological statistic or an unexplained factor of risk, diagnosis, prognosis, or treatment), or with a biological context. We conclude that there is a discrepancy between preclinical faculty knowledge of race and the presentation of race and racial differences in lectures. This discrepancy has implications on medical education. We offer possible explanations for this discrepancy as well as resources for preclinical faculty development to bridge this gap.

Enabling exercise prescription for survivors of cancer.

Although exercise is widely recommended for survivors of cancer, readily implementable approaches for evaluating exercise tolerance enabling exercise prescriptions at appropriate levels of cardiovascular exertion are not always available. We evaluated the utility of modified Harvard Step tests within the context of a standard physical examination for fitness evaluation and exercise prescription for survivors of cancer across a range of age, BMI and exercise history. While 52% of presenting individuals with a past cancer diagnosis were able to complete a 3-min test at pace with a reduced 9-in. step, adoption of self-determined pacing, test duration and completion on a flat surface enabled relative fitness rating and appropriate exercise prescription for the remaining survivors. Younger age and more vigorous exercise histories correlated with completion of the standard 3-min test at pace, but all 9-in. formats led to exercise prescriptions more vigorous than current activity. The physical examination setting expedited inclusion of core and specific muscle group strength testing. The approach is adaptable to a range of health care settings, providers, and patients, providing a shared opportunity for providers and patients to evaluate exercise tolerance. It can be used to further expand incorporation of exercise testing and prescription into routine care.
