The flipped classroom approach in a pediatric anesthesiology fellowship curriculum

Background The flipped classroom approach is well documented to enhance medical education outcomes. Additionally, both the need for online learning materials and the increased demand for medical professionals during the COVID-19 pandemic has made this approach more relevant. The pediatric anesthesiology fellowship curriculum at one institution transitioned from a traditional classroom model to a flipped classroom approach to optimize the educational experience and support learner well-being. Approach Utilizing the American Board of Anesthesiology (ABA) and Accreditation Council for Graduate Medical Education (ACGME) content outlines, a novel, comprehensive curriculum was developed focusing on core clinical material and board review with the goal of providing structured learning while alleviating the burden of completing board review independently to improve work-life balance and reduce the potential for burnout. Evaluation Graduates of the program from 2017 to 2021 evaluated the flipped classroom structure and its perceived impact on their educational outcomes, wellness, and career development via a one-time, voluntary survey. Results indicated improved participation rates and educational benefits with the flipped classroom structure compared to the traditional structure. Fellows preferred the flipped classroom approach to the traditional lecture approach (72.2% vs. 27%), and they preferred custom-made prework material to traditional textbooks and articles. Fellows benefited from having more time for personal activities and other scholarly work, as evidenced by open-ended responses. Implications The flipped classroom structure was perceived as beneficial by pediatric anesthesiology fellows because of increased educational engagement, alleviation of academic burden, and improved wellness due to more time for non-academic activities. Further study is needed to optimize and correlate the new curriculum with objective educational outcomes

Assessing Carbazole Derivatives as Single-Electron Photoreductants

The electron-donating capabilities of carbazoles have stimulated interest in their use as photoinduced single-electron reductants. Due to the modularity of the carbazole, a further broadening and understanding of their reactivity could be achieved by manipulating the structure. Herein, eight carbazole derivatives were synthesized, characterized, and assessed as single-electron photoreductants in the hydrodehalogenation of aryl halides and the arylation of N-methylpyrrole

Initial B-Cell Responses to Transmitted Human Immunodeficiency Virus Type 1: Virion-Binding Immunoglobulin M (IgM) and IgG Antibodies Followed by Plasma Anti-gp41 Antibodies with Ineffective Control of Initial Viremia▿ †

A window of opportunity for immune responses to extinguish human immunodeficiency virus type 1 (HIV-1) exists from the moment of transmission through establishment of the latent pool of HIV-1-infected cells. A critical time to study the initial immune responses to the transmitted/founder virus is the eclipse phase of HIV-1 infection (time from transmission to the first appearance of plasma virus), but, to date, this period has been logistically difficult to analyze. To probe B-cell responses immediately following HIV-1 transmission, we have determined envelope-specific antibody responses to autologous and consensus Envs in plasma donors from the United States for whom frequent plasma samples were available at time points immediately before, during, and after HIV-1 plasma viral load (VL) ramp-up in acute infection, and we have modeled the antibody effect on the kinetics of plasma viremia. The first detectable B-cell response was in the form of immune complexes 8 days after plasma virus detection, whereas the first free plasma anti-HIV-1 antibody was to gp41 and appeared 13 days after the appearance of plasma virus. In contrast, envelope gp120-specific antibodies were delayed an additional 14 days. Mathematical modeling of the earliest viral dynamics was performed to determine the impact of antibody on HIV replication in vivo as assessed by plasma VL. Including the initial anti-gp41 immunoglobulin G (IgG), IgM, or both responses in the model did not significantly impact the early dynamics of plasma VL. These results demonstrate that the first IgM and IgG antibodies induced by transmitted HIV-1 are capable of binding virions but have little impact on acute-phase viremia at the timing and magnitude that they occur in natural infection
