Effective and Time-Efficient Implementation of a Flipped-Classroom in Preclinical Medical Education.

The flipped classroom (FC) model of instruction has inherent barriers to implementation in medical education due to amount of content taught versus time allotted, the widespread adoption of interdisciplinary course structure causing a plethora of instructors responsible for content delivery, and trends to reduce the number of weeks to teach preclinical foundational science. Here we report on a FC model executed in an interdisciplinary endocrinology block in a time-saving manner, while preserving student preferences and satisfaction and improving written assessment performance. In this study, traditional lectures were 100% replaced with pre-session assignments (custom video modules) resulting in less time (- 9 h) spent on first pass learning. In-person, active-learning, case-based sessions were created (+ 8 h) to complete the FC model and achieve higher level understanding. Written assessment performance in the endocrinology block was compared between two cohorts: the FC model and traditional lecture model. The FC model cohort outperformed the traditional lecture cohort on written, multiple-choice assessments (both in-house and NBME assessments). Furthermore, a measured (survey data) student preference for the FC model was observed.

Descriptors in Letters of Recommendation for Otolaryngology Residency Across Gender, Race, and Time.

OBJECTIVE: To determine whether differences exist in the descriptors used in letters of recommendations for Otolaryngology - Head and Neck Surgery (OHNS) residency candidates, comparing race and gender as depicted in visual letters of recommendation (VLORs) from the 2014 and 2019 application cycles. DESIGN: Four hundred thirty-three LORS (284 narrative LORs and 149 standardized LORs) and 63 medical student performance evaluations for 104 candidates who interviewed at the University of Cincinnati OHNS residency program in 2014 and 2019 were analyzed. Descriptors from LORs and medical student performance evaluations were collected by two reviewers and QSR NVivo 12 was used to generate a word cloud that grouped words by synonym and weighted them by frequency. Reviewers coded these synonyms into one of eight descriptor categories. Race and gender were self-reported from residency applications. The average of each category frequency for each race and gender were compared using student t-tests. SETTING: University of Cincinnati OHNS Residency Program. PARTICIPANTS: 104 OHNS applicants that interviewed at the University of Cincinnati in 2014 and 2019. RESULTS: Of the 104 candidates reviewed, 39 were female (37.5%). 66/104 (63%) of applicants identified as white, 31/104 (30%) as non-white, and 7/104 (7%) preferred not to say. No significant differences were found between male vs female descriptors. However, white applicants had more "leadership" descriptors (1.3% vs 0.5%, p = 0.01) and fewer "intelligence" words (6.6% vs 4.8%, p = 0.02) than non-white applicants. Applicants in 2019 were described with more team player (14.2% vs 9.6%, p < 0.0001), leadership (1.6% vs 0.7%, p = 0.047), and reserved (1.7% vs 0.7%, p = 0.02) words, but fewer grindstone (25.2% vs 32.1%, p < 0.0001) and ability/agentic (27.9% vs 32.6%, p < 0.0001) words than applicants in 2014. CONCLUSIONS: In VLORs for OHNS residency, male and female applicants are described similarly, but white applicants are described as leaders more frequently and as intelligent less frequently than non-white counterparts. Regardless, it is encouraging to see applicants described with a more humanistic vocabulary in 2019.

Circadian Biology in Obstructive Sleep Apnea.

Obstructive sleep apnea (OSA) is a complex process that can lead to the dysregulation of the molecular clock, as well as 24 h rhythms of sleep and wake, blood pressure, and other associated biological processes. Previous work has demonstrated crosstalk between the circadian clock and hypoxia-responsive pathways. However, even in the absence of OSA, disrupted clocks can exacerbate OSA-associated outcomes (e.g., cardiovascular or cognitive outcomes). As we expand our understanding of circadian biology in the setting of OSA, this information could play a significant role in the diagnosis and treatment of OSA. Here, we summarize the pre-existing knowledge of circadian biology in patients with OSA and examine the utility of circadian biomarkers as alternative clinical tools.
