Successful Va Ecmo On An Adolescent Pre-B Cell Acute Lymphoblastic Leukemia Patient With Necrotizing Fasciitis From Clostridium Septicum, Jenna Miller, Johanna I. Orrick, Cara Holton, David Juang

Manuscripts, Articles, Book Chapters and Other Papers

Extracorporeal membrane oxygenation (ECMO) has historically been avoided in oncological patients due to perceived risks. However, recent literature suggests improved survival rates for pediatric oncology patients. Additionally, necrotizing fasciitis from Clostridium septicum is associated with high morbidity and mortality, especially in patients with preexisting malignancies. Few studies have explored the outcomes of ECMO in patients with both necrotizing fasciitis and hematologic malignancies. We present a case of a 16-year-old male with pre-B cell acute lymphoblastic leukemia (ALL) and Clostridium septicum necrotizing fasciitis successfully supported with veno-arterial (VA) ECMO. The patient underwent induction chemotherapy for ALL but developed severe septic shock …

The Label Of Low Effort: Exploring Teachers’ Effort-Related Language, Meritocratic Beliefs, And Attribution-Based Responsibility Assignments, Kelly A. Larson

Doctorate in Education

Educators play an integral role in the academic success and future educational trajectory of their students. Yet, in an unjust, hyper-individualistic education system grounded in a meritocratic myth, even the most well-intentioned teachers have a tendency to explain students’ underperformance through a self-protective, deficit-based attribution process that puts the onus of academic achievement almost entirely on students and their families. This recursive cycle is especially damaging for students who do not exhibit effort in normalized, Eurocentric ways. This study examines how teachers’ attributions and responsibility assignments for students’ perceived low-effort behavior are shaped by inequitable meritocratic beliefs and reinforced through …
