    Correlates of College Student Engagement: An Internal Replication

    Though being behaviorally active in the classroom is associated with attractive outcomes, many college students are disengaged. This study examines potential correlates of classroom engagement. Across two waves of data collection, with the second wave providing an internal replication challenge, three variables were consistently related to active classroom engagement. Higher self-esteem, less texting while driving, and lower externally oriented thinking predicted self-report of classroom engagement. Together, the three variables accounted for sixteen percent of the variance in engagement. Adding a fourth variable, gender, led to twenty percent of the variance in engagement being explained

    “Teaching in a War Zone”: A Collective Reflection on Learning from a Diversity Course in Contentious Times

    Diversity courses in teacher education often become sites of conflict and contestation. Numerous proposals have been put forward on how to address these conflicts and contestations through pedagogical interventions and teaching innovations. However, such proposals rarely take into account the impact of broader sociopolitical forces on classroom interactions and learning. In this collective reflection, we document our experiences of navigating a diversity course in highly contentious times when anti-critical race theory campaigns resulted in widespread bans on the teaching of “divisive concepts.” We explore critical incidents and challenging situations to capture the erosion of civility and engagement with evidence. In the context of society-wide attacks on truth, we call on educators, researchers, and advocates to raise their voices in public and political arenas to sustain democracy

    Effect of angiotensin-converting enzyme inhibitor and angiotensin receptor blocker initiation on organ support-free days in patients hospitalized with COVID-19

    IMPORTANCE Overactivation of the renin-angiotensin system (RAS) may contribute to poor clinical outcomes in patients with COVID-19. Objective To determine whether angiotensin-converting enzyme (ACE) inhibitor or angiotensin receptor blocker (ARB) initiation improves outcomes in patients hospitalized for COVID-19. DESIGN, SETTING, AND PARTICIPANTS In an ongoing, adaptive platform randomized clinical trial, 721 critically ill and 58 non–critically ill hospitalized adults were randomized to receive an RAS inhibitor or control between March 16, 2021, and February 25, 2022, at 69 sites in 7 countries (final follow-up on June 1, 2022). INTERVENTIONS Patients were randomized to receive open-label initiation of an ACE inhibitor (n = 257), ARB (n = 248), ARB in combination with DMX-200 (a chemokine receptor-2 inhibitor; n = 10), or no RAS inhibitor (control; n = 264) for up to 10 days. MAIN OUTCOMES AND MEASURES The primary outcome was organ support–free days, a composite of hospital survival and days alive without cardiovascular or respiratory organ support through 21 days. The primary analysis was a bayesian cumulative logistic model. Odds ratios (ORs) greater than 1 represent improved outcomes. RESULTS On February 25, 2022, enrollment was discontinued due to safety concerns. Among 679 critically ill patients with available primary outcome data, the median age was 56 years and 239 participants (35.2%) were women. Median (IQR) organ support–free days among critically ill patients was 10 (–1 to 16) in the ACE inhibitor group (n = 231), 8 (–1 to 17) in the ARB group (n = 217), and 12 (0 to 17) in the control group (n = 231) (median adjusted odds ratios of 0.77 [95% bayesian credible interval, 0.58-1.06] for improvement for ACE inhibitor and 0.76 [95% credible interval, 0.56-1.05] for ARB compared with control). The posterior probabilities that ACE inhibitors and ARBs worsened organ support–free days compared with control were 94.9% and 95.4%, respectively. Hospital survival occurred in 166 of 231 critically ill participants (71.9%) in the ACE inhibitor group, 152 of 217 (70.0%) in the ARB group, and 182 of 231 (78.8%) in the control group (posterior probabilities that ACE inhibitor and ARB worsened hospital survival compared with control were 95.3% and 98.1%, respectively). CONCLUSIONS AND RELEVANCE In this trial, among critically ill adults with COVID-19, initiation of an ACE inhibitor or ARB did not improve, and likely worsened, clinical outcomes.
