    A Mixed Methods Study on the Effect of Flipping the Undergraduate Medical Classroom

    The flipped classroom model is increasingly being adopted in healthcare education, despite the fact that recent systematic reviews in the nursing and medical education literature suggest that this method of instructional design is not inherently better or worse than the traditional classroom. In this study, we used a sequential, explanatory mixed methods design to assess the impact of flipping the hepatology classroom for preclinical medical students. Compared to students in the traditional classroom, students in the flipped classroom had significantly lower mean (SD) ratings of their learning experiences (3.48 (1.10) vs. 4.50 (0.72), p < 0.001, d = 1.10), but better performance on the hepatology content of the end-of-course examination (78.0% (11.7%) vs. 74.2 (15.1%), respectively, p < 0.01, d = 0.3). Based upon our qualitative data analyses, we propose that the flipped classroom induced a change in the learning process of students by requiring increased preparation for classroom learning and promoting greater learner autonomy, which resulted in better retention of learned material, but reduced enjoyment of the learning experience. This dissonance in outcomes is captured in the words of one flipped classroom student: “…I hated it while I was learning it, but boy did I remember it…”. Based upon our dissonant outcomes and the inconsistent findings in the literature, we feel that there is still equipoise regarding the effectiveness of the flipped classroom, and further studies are needed to describe ways of making the flipped classroom a more effective (±more enjoyable) learning experience.

    Spontaneous Regression of Hepatocellular Carcinoma and Review of Reports in the Published English Literature
    (2019-03-31) Chohan, Moaz B. Y.; Taylor, Nick; Coffin, Carla; Burak, Kelly W.; Bathe, Oliver F.
    Background. Spontaneous regression of hepatocellular carcinoma (HCC) is a rare event, although it has been described by numerous groups. The long-term fate of individuals experiencing an SR is not well described, and the underlying mechanism(s) of SR are unknown. Case Presentation: A 79-year-old Asian female with metastatic HCC taking only valsartan for hypertension had a marked reduction in tumor dimension in the primary tumor and the pulmonary metastases. Serum alpha-fetoprotein (AFP) decreased from 17,833 μg/L to 26 μg/L. Her disease progressed after 71 months, and she died shortly after. In a review of 66 patients with SR reported in the English literature, median survival was 83 months. Median survival in 37 cases that underwent resection after SR was 108 months. Conclusions. The case and a review of the literature illustrate that SR is often durable and associated with an excellent prognosis. Understanding the underlying mechanism of SR may point to novel therapeutic strategies.
